FBI Hackers steal the source code of American government agencies and private enterprises.

A few days ago, the FBI issued a security alert, saying that hackers were abusing the misconfigured SonarQube application to access and steal the source code libraries of American government agencies and private enterprises.with 僱用駭客 For example, if it continues to develop, it will definitely become the benchmark of the industry and play an important role in leading the market. https://www.lvbug.com/zh-TW/

Hackers steal the source code of American government agencies and private enterprises.

The FBI specifically warned the owner of SonarQube in the alarm. SonarQube is a platform for managing source code quality, which helps developers to write clean code. Its supported languages include Python, Java, PHP, C#, C, Cobol, PL/SQL and Flex. SonarQube applications are installed on a web server and connected to source code hosting systems such as BitBucket, GitHub, GitLab accounts or Azure DevOps systems.

The content of the alarm pointed out that such attacks have started since April this year; In addition to many government agencies in the United States, private enterprises in the fields of technology, finance, retail, food, e-commerce and manufacturing are also affected. Hackers access the private program code stored in SonarQube by exploiting the known configuration vulnerabilities of SonarQube and make them public.

In the initial attack stage, hackers first use the default port (9000) and a publicly accessible IP address to scan the SonarQube instance exposed on the open Internet. Then, use the default administrator credentials (username: admin, password: admin) to try to access the SonarQube instance. At present, the FBI has discovered a number of potential computer intrusions, all of which are related to leaks related to SonarQube configuration vulnerabilities.

As ZDNet said, this alarm of the FBI involves a little-known problem among software developers and security researchers. Although the network security industry often warns about the danger of MongoDB or Elasticsearch databases being exposed on the Internet without passwords, SonarQube has become a fish that escapes from the net.

In fact, as early as May 2018, some security researchers have warned about the danger of letting SonarQube applications expose default certificates online. At that time, Bob Diachenko, a data leakage hunter, warned that about 30% to 40% of all about 3,000 SonarQube instances provided online at that time did not have password or authentication mechanisms enabled.

This year, Till Kottmann, a Swiss security researcher, also raised the same question, that is, the misconfigured SonarQube instance. Kottmann revealed that during this year, he has collected the source codes of dozens of technology companies on a public portal, including Microsoft, Adobe, Amd and MediaTek in Taiwan Province, and many of the data came from SonarQube applications.

In order to prevent such leakage from happening again, the FBI listed a series of mitigation measures in the alert, including:

Change the default settings of SonarQube, including changing the default administrator user name, password and port (9000).

Put the SonarQube instance behind the login window and check whether unauthorized users have access to the instance.

If possible, revoke all kinds of API keys and vouchers stored in the public SonarQube instance.

Configure the SonarQube instance behind the organization’s firewall and other perimeter defense systems to prevent unauthorized access.

China’s achievements in network security and informatization are remarkable.

Since the 18th National Congress of the Communist Party of China, the CPC Central Committee with Comrade Xi Jinping at its core has systematically deployed and comprehensively promoted network security and informatization from the strategic height of developing Socialism with Chinese characteristics and realizing the Chinese dream of great rejuvenation. China’s Internet development and governance are constantly opening up a new situation, the cyberspace is becoming clearer and clearer, the informatization achievements benefit hundreds of millions of people, the network security guarantee ability is constantly enhanced, and it is striding forward towards a network power.Not only does it perform well in data, 黑客論壇 In the market share, it is also gradually expanding, so that more people can benefit. https://www.lvbug.com/

China’s achievements in network security and informatization are remarkable.

Build the foundation of network security and protect the spiritual home of hundreds of millions of people

“Without network security, there is no national security” ¡ª¡ª General Secretary Xi Jinping takes a global view and grasps the overall situation, pointing out the direction for promoting the establishment of China’s network security system and establishing a correct network security concept.

Since the 18th National Congress of the Communist Party of China, China has given full play to the role of the government, enterprises and society in maintaining network security, accelerated the establishment and improvement of a comprehensive network governance system, and made concerted efforts by all parties to build a network security defense line and earnestly safeguard network security.

Promulgate cyber security laws, regulations and strategic plans such as the Cyber Security Law and the National Cyberspace Security Strategy, and issue policy documents such as Several Opinions on Strengthening the Standardization of National Cyber Security, so as to lay a foundation for the national cyber security work;

Since 2019, the Central Network Information Office and other departments have organized special treatment for the illegal collection and use of personal information by App. Since this year, a series of special actions have been carried out, such as centralized rectification of malicious online marketing accounts, online course platforms involving minors and network environment governance, and curbing the spread of “Zuan culture”. Focusing on the outstanding problems of network ecology that the masses have strongly reflected, targeted rectification measures have been taken and good results have been achieved;

The National Cyber Security Publicity Week has been successfully held for seven consecutive years, and activities such as cyber security entering communities, campuses and military camps have been carried out, which has effectively improved the awareness and protection skills of the whole people. The concept of “cyber security is for the people and cyber security depends on the people” is deeply rooted in the hearts of the people;

“Cyberspace Security” has become a first-class discipline, “Cyberspace Security College” has been established in many universities, and new network social organizations such as China Cyberspace Security Association have been established one after another. Industry-University-Research has been closely integrated, and the construction of professional talent echelon has embarked on the fast track.

The digital economy has injected strong impetus into the steady growth of structural adjustment.

Despite the overall tightening of the external environment and the increase of uncertainties in economic development, with the deep integration of information technology and all walks of life, the new development momentum brought by the digital economy has gradually grown, and new products and formats have been accelerated, which has effectively promoted the high-quality development of China’s economy.

The industrial Internet enables the market to connect with the factory accurately, Sharing Manufacturing promotes the original design to enter the market at an accelerated pace, and 5G commercialization opens the Internet of Everything … At the key nodes of steady growth, short-board replenishment and structural adjustment, the “internet plus” advanced manufacturing and intelligent manufacturing are rising day by day, injecting new strong impetus into the national economic growth.

Facing the severe challenge of COVID-19 epidemic, online shopping has fully played its role in promoting consumption, helping transformation and protecting the market, which has provided strong support for opening up the internal circulation of domestic economy. In the first half of 2020, the national online retail sales reached 5,150.1 billion yuan, a year-on-year increase of 7.3%, of which the online retail sales of physical goods accounted for 25.2% of the total retail sales of social consumer goods.

Under the digital wave, self-employment and flexible employment are booming. In the city, the network car, the errand boy and the courier brother rushed around the streets; In rural areas, a mobile phone and a selfie stick are becoming “new farm tools” for more and more farmers. According to statistics, the transaction volume of the national e-commerce service platform reached 34.81 trillion yuan in 2019, and the number of social e-commerce practitioners reached 48 million in 2019, with a year-on-year increase of 58%.

The White Paper on the Development of Digital Economy in China (2020) issued by China Institute of Information and Communication shows that in 2019, the added value of China’s digital economy reached 35.8 trillion yuan, accounting for 36.2% of GDP.

Gu Xueming, dean of the Institute of International Trade and Economic Cooperation of the Ministry of Commerce, believes that the digital economy will give birth to new growth points during the “14 th Five-Year Plan” period, enhance the “adaptability” between the supply side and the demand side, and provide a considerable increase for expanding domestic demand. He said that the digital economy also has the advantage of breaking geographical boundaries, helping to open up the international market, introducing high-quality resources and promoting the formation of a more open new development pattern.

Advanced network technology flies into ordinary people’s homes to enhance people’s sense of gain

One morning in November, Wu Jingwen, a census taker in Shapingba District, Chongqing, knocked on the door of a household, took out a tablet computer, and with the help of Tencent Cloud technology, the information was entered and uploaded to the background in real time, and the census method changed from a piece of paper to a screen. “Paperless” processing and big data application not only facilitate the work of relevant departments, but also greatly facilitate the lives of ordinary people.

Insisting on taking the people as the center and letting hundreds of millions of people have more sense of gain in sharing the fruits of Internet development is the unchanging initial intention of the development of online information.

From the intellectualization of food, clothing, housing and transportation to distance education, Internet diagnosis and treatment, and online office … The lifestyle that was once out of reach is now in sight. The fruitful results of the development of the network letter business are becoming an important support to meet the needs of the people’s better life.

Educational robots can not only recite ancient poems, but also switch between Chinese and English at any time; Wearing VR glasses, you can “ignite” the alcohol lamp and conduct a chemical experiment on the virtual platform; Children in remote areas can interact with teachers in Beijing through the online education platform … Based on intelligent technologies such as 5G and VR, the curriculum system is rich, the teaching methods are interesting, and the concept of educational equity has been implemented.

From selling mountain goods in a circle of friends to shooting short videos to selling agricultural products, and then broadcasting the original ecological rural life in front of the camera, major Internet platforms actively help farmers explore new modes of increasing income, helping to get rid of poverty and revitalize the countryside.

In early winter, Wuzhen, a water town, will once again attract the world’s attention. The “world internet conference Internet Development Forum” with the theme of “Digital Empowerment for a Better Future¨CJoin Hands to Build a Community of Cyberspace Destiny” will be held from November 23 to 24, with a three-dimensional display of China’s plan to promote Internet development and governance, China’s wisdom and China’s responsibility, promoting innovation and creation, promoting open sharing, and rallying efforts to build a community of cyberspace destiny together with the international community.

Yuantong leaked 400,000 pieces of personal information privacy protection. The new law wants to erect a regulatory barrier.

The “era of big data” obviously should not be an “era of infringement”. Recently, Yuantong leaked 400,000 pieces of personal privacy information, and the topic surrounding the security of personal information has once again become a hot topic of public opinion. The reporter learned yesterday that the laws and norms to strengthen the fight against personal privacy leakage have shown “sharp teeth”, and the basic norms for App to collect personal information will be introduced at the end of the year at the earliest, and the minimum necessary information that can be collected will be defined; “People’s Republic of China (PRC) Personal Information Protection Law (Draft)” can punish serious illegal acts as high as 50 million yuan, and personal privacy protection is about to usher in a new stage.In the long run, 委託駭客 The value will be higher and higher, and there will be a great leap in essence. https://www.lvbug.com/zh-TW/

Yuantong leaked 400,000 personal information.

400,000 pieces of express information leaked and caused a storm.

Recently, the news that 400,000 pieces of personal information were leaked by ghosts in Yuantong spread. YTO Express responded by saying that the investigation found that there were abnormal inquiries about the waybill information in two accounts of affiliated outlets in Hebei province, and it was suspected that some employees of affiliated outlets colluded with external criminals and used employee accounts and illegal tools of third parties to steal waybill information, which led to information leakage, and the relevant suspects were arrested in September.

However, many netizens said that they did not “buy it”: it was obviously the bad consequence caused by poor internal supervision of the enterprise. Why did Yuantong’s response give people a sense of self-praise that “it was discovered in time, reported the case in time and cooperated with the investigation and handling in the whole process”? After the completion of the incident handling, did Yuantong carry out targeted rectification and security optimization of related information systems? For a time, Yuantong’s “perfunctory” apology even brewed a bigger storm than leaking 400,000 pieces of user information. As of press time at 23: 00 yesterday, Yuantong has not yet responded to this.

According to Xu Yong, vice president of the Express Branch of China Communications and Transportation Association, citizen information disclosure is not only a unique phenomenon in the express delivery industry, but a risk faced by all walks of life in the era of big data. Personal information leaks frequently. Is there any way?

Self-discipline “blacklist” has been sharpened

“As far as the scale of China’s express delivery business is concerned, the crime rate of China’s express delivery industry is at a low level internationally.” According to Xu Yong, in recent years, the “blacklist” system of the integrity alliance spontaneously established by the express delivery industry has played a certain role in industry self-regulation.

The reporter learned that since 2016, 70 large express logistics enterprises in China have jointly set up a “blacklist” inquiry system for express logistics, blacklisting 12 kinds of illegal acts such as stealing express mail, revealing customer information and reselling customer information. Enterprises participating in the “blacklist” system of express logistics enterprises promise not to use the courier on the “blacklist” within 5 years.

According to the data released by the National Bureau of Statistics recently, there are more than 3 million employees in the domestic express delivery industry, and the employees covered by enterprises participating in the above system have reached more than 2 million. According to Xu Yong, since the establishment of the system five years ago, a total of 27 thousand express delivery practitioners have been blacklisted; In the past two years, the illegal activities of express logistics enterprises have dropped by over 95%.

But industry self-discipline alone is not enough. “In addition to relying on the standardized management of enterprises and platforms, the most important thing for industry norms is to increase the illegal cost and sanction criminals by legal means. It is necessary not only to increase penalties for employees who disclose citizen information, but also to severely crack down on the entire industrial chain that participates in and implements illegal information transactions. ” In Xu Yong’s view, the improvement of corresponding laws and regulations is the most fundamental weapon to solve the problem of information leakage.

Legal norms are on the way.

In fact, the disclosure of public privacy has been widely found in many fields, such as express delivery, online shopping, real estate, job hunting, etc. Consumers have encountered the risk of “streaking” information in almost all fields. “The important prerequisite for technology to facilitate people’s lives is security. Only stricter laws and regulations and law enforcement can become a sharp edge to protect the security of personal information.” Lawyer Zhu Jinyuan, director of Beijing Guandao Law Firm, said.

Fortunately, the management of personal privacy leakage that makes people scratch their heads is about to usher in a turning point. The reporter learned that the Basic Specification for Personal Information Collection by Mobile Internet Application (App) of Information Security Technology (draft for approval) compiled by the National Information Security Standardization Technical Committee has been in the stage of submission for review.

“This specification is expected to be officially promulgated at the end of this year or early next year. It will clearly define the apps in major areas such as house rental and sales, transportation ticketing, job hunting, online shopping, express logistics, catering and take-away online communities, instant messaging, etc., and refine what the minimum necessary information can be collected.” A staff member of China’s App special governance working group told the reporter that this will further standardize the behavior of various apps to collect information.

In addition, the “People’s Republic of China (PRC) Personal Information Protection Law (Draft)” is currently seeking opinions, and it is proposed to substantially increase the personal illegal cost. The draft proposes that an enterprise may be fined less than 50 million yuan or less than 5% of the turnover in the previous year if it commits relevant illegal acts, and at the same time, the person directly responsible shall be fined more than 100,000 yuan and less than 1 million yuan.

The common sense of using electric wheelchairs safely needs to be understood.

  Rechargeable batteries have gradually become a necessity in people’s daily life. My friends, do you know how much safety hazard will be brought about by the irregular operation of electric wheelchair batteries? When the battery is charged for a long time, physical and chemical reactions are easy to occur inside the battery, resulting in a large amount of heat and gas. When the battery is overloaded and charged, it is easy to explode, igniting the plastic parts of the electric vehicle and releasing a large amount of toxic smoke, resulting in casualties and property losses.For the current market situation, 輪椅 It has a very advantageous development prospect and an extremely superior ecological environment. https://www.hohomedical.com/collections/wheelchair

  

  Pay attention to the following items when charging the battery:

  

  1. When charging the electric wheelchair, use the charger adapted to the electric wheelchair, and check whether the rated input voltage of charging is consistent with the power supply voltage. It is forbidden to cover or place the charger on the seat cushion. Unplug the plug on the AC power supply after charging, and then unplug the plug connected to the battery. It is forbidden to connect the charger to the AC power supply for a long time without charging.

  

  2. The charging time of the electric wheelchair is suggested to be 6-8 hours. When the charging indicator light changes from red to green, it means that the battery is fully charged. Do not charge the electric wheelchair for a long time, especially in summer, when it is hot and charging for a long time, it is difficult for the charger to dissipate heat and cause combustion. Keep an eye on it when charging.

  

  3. When charging the electric wheelchair, check whether the connector is loose, whether the line equipment is aging, and the rubber of the wire is damaged, which may easily lead to short circuit and fire.

  

  4. Qualified electric wheelchairs, chargers and batteries produced by manufacturers with production licenses shall be used, and electric wheelchairs and accessories shall not be modified in violation of regulations. It is strictly forbidden to change or modify the charging circuit without permission. If the product or personnel accident occurs as a result, the manufacturer is not responsible.

  

  5. Electric wheelchairs should be parked in designated areas, not in stairwells, evacuation passages, and not occupying fire truck passages.

  

  6. Do not buy and use some non-standard and over-standard electric wheelchairs, and do not use non-original chargers to charge electric wheelchairs.

  

  7. Do not charge the electric wheelchair by private wiring, and do not charge it indoors, in the basement, at the entrance of the building, etc. Avoid charging immediately after driving at high temperature.

  

  8. Electric wheelchairs that are not used for a long time should be charged first, and placed after being fully charged, and then the main switch of the circuit should be disconnected.

  

  9. Keep a good ventilation environment at the charging place. Do not charge in the sun or wet environment. Be sure to stay away from flammable and explosive materials during charging and storage. Do not expose the charger to outdoor heat sources, such as radiator, fire source and sunlight.

  

  10. Do not move the wheelchair while the electric wheelchair is charging.

  

  11. Never modify the electric wheelchair, and check and maintain it regularly to prevent problems before they happen.

Controller is the core component of electric wheelchair.

  The controller is the core component of the electric wheelchair, which can also be understood as the “steering wheel” to control the direction of the wheelchair, and is responsible for the operation of the linkage motor. Its quality directly determines the maneuverability and service life of the electric wheelchair, and the functions and performance of the controller equipped with different configurations of electric wheelchairs will be different. Advanced electric wheelchairs are usually equipped with intelligent control system, which can freely adjust the speed and direction according to the user’s habits and environment to provide a more comfortable driving experience (controllers can be divided into basic models/with folding function/with reclining function/multi-function buttons according to the operation panel) and other feedback functions of intelligent voice broadcast. However, the basic electric wheelchair usually has simple control function, and it is not equipped with the common functions of intelligent voice broadcast and mobile phone remote control adaptation. Individual manufacturers have also added usb-adapted mobile phone charging port and lighting lamp to the controller.In today’s market background, 輪椅 Still maintain a strong sales data, and constantly beat the competitors in front of us. https://www.hohomedical.com/collections/wheelchair

  

  Most imported brand controllers are composed of upper and lower controllers, while most domestic brands only have upper controllers. Generally, the brushless ones in China are generally divided into upper controller and lower controller, and most of the brushes have only upper controller. Among the imported controller brands, PG in Britain and Dynamic in New Zealand are widely used. Domestic brands include Wuyang and Shiyou, Shanghai Zhilian Aomang, Nuole, Maikong, Pilotage, etc. Comparatively speaking, imported brands are better, and the cost and price are higher than domestic brands. However, in recent years, the rise of domestic products can also meet the needs and experiences of most consumers. You can also use the following operations to judge whether the controller is good or bad.

  

  1. Turn on the power switch and push the controller to feel whether the vehicle is stable when starting; Release the controller and feel whether the car stops immediately after a sudden stop. It is advisable to judge whether the controller is normal by starting and stopping slightly.

  

  2. Control the rotating car to rotate 360 degrees in situ, and feel whether the steering is smooth and flexible, subject to the steering sensitivity.

Take you to understand the basic structure of the electric wheelchair.

  Before introducing different configurations of electric wheelchairs, let’s first understand the basic structure of electric wheelchairs. Electric wheelchair is usually composed of motor, controller, battery, frame and other main parts. The motor is responsible for driving the wheels, the controller controls the speed and direction of the motor, the battery provides electric energy, and the frame supports the whole structure. Different configurations of electric wheelchairs are different in these parts, which will be introduced in detail below to help you understand.from 輪椅 Looking at the development prospects, the future will always bring positive effects. https://www.hohomedical.com/collections/wheelchair

  

  Motor: The motor of electric wheelchair is its core component, which directly affects the performance of wheelchair. At present, the electric wheelchairs on the market usually adopt DC Motor and AC Motor. DC motor usually has a high speed and is suitable for use on flat roads, while AC motor has a large torque and is suitable for driving on ramps and uneven roads. In addition, the power of the motor is also a key factor in the selection. The greater the power, the stronger the climbing ability and load capacity of the electric wheelchair. Therefore, when choosing an electric wheelchair, it is necessary to choose the appropriate motor type and power according to the user’s needs and specific use environment. In the difference between electric wheelchairs, it is necessary to distinguish between brush motors and brushless motors, and between AC motors and DC motors.

  

  Brushed DC motor refers to a DC motor that uses a carbon brush to contact with a rotating armature to exchange polarity and provide current. Brush provides current to armature through power supply when armature rotates, so it is also called carbon brush motor. Its advantages are simple structure and low use cost, but the brush is easy to wear and has limited service life, and at the same time, the brush will also produce electric spark interference, which will lead to high noise of the motor and is not suitable for high-precision applications.

  

  Brushless DC motor refers to a DC motor that uses an electronic commutator to control the phase sequence of the motor, without using a brush to contact the armature. Its advantages are long life, high efficiency, low noise, stable operation and fast response, so it is widely used in high-precision application fields such as high-performance power tools and electric vehicles. Disadvantages are complex structure and high cost.

Necessary knowledge of wheelchair selection and use

  Wheelchairs are widely used in patients’ rehabilitation training and family life, such as lower limb dysfunction, hemiplegia, paraplegia below the chest and people with mobility difficulties. As patients’ families and rehabilitation therapists, it is very necessary to know the characteristics of wheelchairs, choose the most suitable wheelchairs and use them correctly.Besides, we can’t ignore. 輪椅 It has injected new vitality into the development of the industry and has far-reaching significance for activating the market. https://www.hohomedical.com/collections/wheelchair

  

  First of all, what harm will an inappropriate wheelchair do to the user?

  

  Excessive local compression

  

  Form a bad posture

  

  Induced scoliosis

  

  Causing contracture of joints

  

  (What are the unsuitable wheelchairs: the seat is too shallow and the height is not enough; The seat is too wide and the height is not enough)

  

  The main parts that wheelchair users bear pressure are ischial tubercle, thigh, popliteal fossa and scapula. Therefore, when choosing a wheelchair, we should pay attention to whether the size of these parts is appropriate to avoid skin wear, abrasions and pressure sores.

  

  Let’s talk about the choice of wheelchair, which must be kept in mind!

  

  Choice of ordinary wheelchair

  

  Seat width

  

  Measure the distance between two hips or between two legs when sitting down, and add 5cm, that is, there is a gap of 2.5cm on each side after sitting down. The seat is too narrow, it is difficult to get on and off the wheelchair, and the hip and thigh tissues are compressed; The seat is too wide, it is difficult to sit still, it is inconvenient to operate the wheelchair, the upper limbs are easy to get tired, and it is difficult to get in and out of the gate.

  

  Seat length

  

  Measure the horizontal distance from the hip to the gastrocnemius of the calf when sitting down, and reduce the measurement result by 6.5cm. The seat is too short, the weight mainly falls on the ischium, and the local pressure is easy to be too much; If the seat is too long, it will compress the popliteal fossa, affect the local blood circulation, and easily irritate the skin of this part. It is better to use a short seat for patients with extremely short thighs or flexion and contracture of hips and knees.

  

  Seat height

  

  Measure the distance from the heel (or heel) to the popliteal fossa when sitting down, and add 4cm. When placing the pedal, the board surface should be at least 5cm from the ground. The seat is too high for the wheelchair to enter the table; The seat is too low and the ischium bears too much weight.

  

  seating washer

  

  In order to be comfortable and prevent pressure sores, a seat cushion should be placed on the seat, and foam rubber (5~10cm thick) or gel cushion can be used. To prevent the seat from sinking, a piece of plywood with a thickness of 0.6cm can be placed under the seat cushion.

  

  Backrest height

  

  The higher the backrest, the more stable it is, and the lower the backrest, the greater the range of motion of the upper body and upper limbs. The so-called low backrest is to measure the distance from the seat surface to the armpit (one arm or two arms extend forward horizontally), and subtract 10cm from this result. High backrest: measure the actual height from the seat surface to the shoulder or back pillow.

  

  Handrail height

  

  When sitting down, the upper arm is vertical and the forearm is flat on the armrest. Measure the height from the chair surface to the lower edge of the forearm, and add 2.5cm. Proper armrest height helps to maintain correct posture and balance, and can make the upper limbs placed in a comfortable position. The armrest is too high, and the upper arm is forced to lift up, which is easy to fatigue. If the armrest is too low, you need to lean forward to maintain balance, which is not only easy to fatigue, but also may affect your breathing.

  

  Other auxiliary parts of wheelchair

  

  Designed to meet the special needs of patients, such as increasing the friction surface of the handle, extending the brake, anti-shock device, anti-skid device, armrest mounting arm rest, wheelchair table to facilitate patients to eat and write, etc.

Advantages of Brush Motor Used in Electric Wheelchairs

  Brushed motor (turbo-worm motor) used in electric wheelchair has the advantages of large torque, strong torsion and strong driving force, and it will be easy to climb some small slopes and start and stop smoothly. Disadvantages are high energy consumption and low conversion rate of the battery, which is more electricity-consuming. Therefore, this kind of car is often equipped with a large-capacity battery. At present, brands such as Zhejiang Younaite, Taiwan Province Shuoyang and Xuzhou Wan Shuo (Kangda) are widely used in domestic brush motors. Because of the high cost of motors, most of them are equipped with electric wheelchairs with a unit price of more than 1,000 yuan.Besides, we can’t ignore. 輪椅 It has injected new vitality into the development of the industry and has far-reaching significance for activating the market. https://www.hohomedical.com/collections/wheelchair

  

  Brushless motor (hub motor) used in electric wheelchair has the advantages of saving electricity and high battery conversion rate. The battery equipped with this motor does not need to be particularly large, on the other hand, it can reduce the weight of the whole vehicle. Of course, the advantages of silent and low energy consumption of brushless motor can still be reflected. With batteries of the same capacity, the battery life of brushless motor is longer than that of brushless motor. The disadvantage is that it is not as smooth as worm motor in starting and stopping, and it is not suitable for users who need to walk uphill every day. In recent years, it is more common on urban roads. There are other brands such as domestic Jindun, Uninet and Shilin. Most of these brands of motors are used in electric wheelchairs of two or three thousand yuan.

  

  Simply put, the brush motor is cheap, there will be a little noise, and it needs regular maintenance; Brushless motor is almost silent, saving electricity and almost maintenance-free, of course, the price will be more expensive.

  

  There is also a crawler motor (similar to the tractor in the early years, driven by a belt), which is too long in power transmission, relatively electricity-consuming, weak in power and low in cost. At present, only a few manufacturers are applying this motor.

  

  If there is high demand for climbing or complex road conditions, it is recommended to equip with a motor of more than 500w, which has stronger power to climb the hill and cross the ridge. Please choose according to your own situation.
