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.Down-to-earth right 電動輪椅價錢 In-depth research is the only way to pursue development. https://www.hohomedical.com/collections/light-weight-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.

Is the electric wheelchair a brushless motor or a brush motor

  Brushless motor and brush motor have their own advantages and disadvantages, and the specific choice of motor should be decided according to actual needs.In some cases, 電動輪椅價錢 The advantages will become more and more obvious, and it will be able to develop indomitable after market tests. https://www.hohomedical.com/collections/light-weight-wheelchair

  

  Brush motor is a common motor used in early electric wheelchairs. Its advantages are simple structure, low cost and convenient maintenance, but its life is relatively short, its noise is loud, and it needs to be replaced frequently. Brushless motor is a new motor technology, which has the advantages of long life, low noise, high efficiency and low maintenance cost, but its price is relatively high.

  

  Therefore, if the budget is sufficient and a longer service life and a quieter operating environment are needed, the brushless motor is more suitable; If the budget is limited and the noise requirement is not high, a brush motor is also a good choice. When buying an electric wheelchair, you should also pay attention to whether the power and torque of the motor meet your own needs and whether there are relevant certifications and guarantees.

  

  Is the electric wheelchair as long as possible?

  

  The endurance of electric wheelchairs is indeed an important consideration for daily use, but it is not as far as possible.

  

  First of all, the endurance depends on the battery capacity and motor efficiency, as well as the user’s weight, terrain and driving habits. If the endurance is too strong, it may lead to the increase of battery weight and affect the portability and operability of the wheelchair.

  

  Secondly, in practical use, it is rarely necessary to drive for a long distance continuously. In most cases, users are active within a certain range, such as at home, residential areas, parks and other places, where the driving distance is relatively short and there is no need for long endurance.

  

  Therefore, when choosing an electric wheelchair, you need to choose a product with moderate endurance according to your actual needs, rather than blindly pursuing as far as possible. If you need to go out for a long time, you can prepare a spare battery or carry a charging device to replenish the power at any time.

  

  Is the electric wheelchair a lead-acid battery or a lithium battery?

  

  Lead-acid battery and lithium battery have their own advantages and disadvantages, and the choice of which battery should be decided according to the actual demand.

  

  Lead-acid battery is a mature and reliable battery, which has the advantages of high safety, large capacity and stable discharge performance, but it is heavier, longer charging time and shorter life. Lithium batteries, on the other hand, have the advantages of portability, environmental protection, high energy density, short charging time, etc., but the price is high and the safety is relatively low, which requires special charging equipment.

  

  Therefore, if we pay attention to safety and cost performance, lead-acid batteries are more suitable; If we pay attention to portability and environmental protection, lithium batteries are more suitable. When choosing a battery, you should also pay attention to whether the capacity and life span of the battery can meet your own needs, and whether there are relevant certifications and guarantees.

  

  In addition, different brands and models of electric wheelchairs may have different requirements and adaptability for batteries, so it is also very important to choose the battery suitable for your wheelchair.

In this regard, Youyou said that appearance is not a bargaining chip for reckless behavior.

India_s stock index drops by its largest in 20 weeks

precisely because My WordPress The rapid development of, so also brought new opportunities to the industry. https://gjsign.com

According to a report by India’s Politico on March 15, the Bombay Stock Exchange Sensitive Index (SENSEX) and N Index fell for the first time in a single week after rising for four weeks. Both indices fell about 2% this week, the biggest weekly decline in 20 weeks.

The SENSEX index fell 062% on the day to close at 7264343 points. The N50 index of the National Stock Exchange of India (NSE) fell 0.56% to close at 2202335 points.

The Bombay Stock Exchange (BSE) mid-cap index also closed down 0.51%. However, the BSE Small Cap Index bucked the trend and closed up 0.25%.

On the weekly chart, the benchmark SENSEX index fell 22% for the week and the N index fell 21%. This is the largest weekly decline since October 2023. The BSE mid-cap and small-cap indices fell about 4% and 6% respectively this week.

From an industry perspective, the N-Metal Index and FMCG Index closed flat, while all other industry indices closed down.

The biggest declines were in the oil and gas industry and the automobile industry, with declines of 198% and 157% respectively. The N Bank index fell 0.42%.

As some funds release stress test results, they are confident that their portfolios can cope with volatile market conditions.

In global stock markets, the weakness is believed to be driven by discouraging U.S. economic data and weakening expectations of a Federal Reserve interest rate cut.

Some reports showed that the U.S. industrial producer price index (PPI) exceeded expectations in February. At the same time, the number of people applying for and receiving unemployment benefits was lower than expected. These factors weaken the Fed’s case for interest rates.

Market participants will be closely watching the Fed’s monetary policy stance next week. Most expect the Fed to keep interest rates unchanged and start cutting rates from the end of June or July. (Compiled by Zhu Jie)

Do you know all this knowledge about electric wheelchair

  This paper will start from the earliest development stage of electric wheelchair and trace its development course. The paper quotes the related introduction of motors on the Internet, and introduces its technical progress and the differences of electric wheelchairs with different configurations, including motors, controllers, batteries and frame materials.according to 電動輪椅 Industry veterans said that its development will still be in a good situation. https://www.hohomedical.com/collections/light-weight-wheelchair

  

  It also expounds what kind of life the electric wheelchair can improve for the disabled and the elderly, and probes into its positive influence on the life of the disabled, hoping to encourage the disabled and people with mobility difficulties to actively and confidently use reasonable tools to help them improve their quality of life.

  

  Since the 1990s, the mechanical design of wheelchair has basically been finalized, and it has made great progress mainly in the scientific and technological content, and has become a completely customizable small vehicle. For example, the famous physicist Hawking’s wheelchair has a built-in computer so that Hawking can control the wheelchair independently.

  

  The origin of electric wheelchairs can be traced back to the early 20th century. The earliest electric wheelchair was invented by Canadian engineer George Klein, who designed an electric wheelchair to help soldiers who lost their walking ability because of disability during World War II. Clay’s core design is still the design basis of electric wheelchair because the wheelchair is endowed with more comprehensive functions. Although this kind of electric wheelchair is relatively heavy, it provides a way for the disabled to move independently and greatly improves their quality of life.

On July 16, local time, the Houthi armed forces in Yemen released a video of the organization attacking the Red Sea sailing ship Chios Lion (CL).

The Houthi armed forces issued a statement saying that the ship violated the Houthi ban and headed for an Israeli port, so it was attacked by the Houthi armed forces on the 15th.

After the attack, the U.S. Central Command said no casualties were caused.

The Houthi armed forces said they would continue to attack ships related to or bound for Israel until Israel stops attacks on the Gaza Strip and lifts the blockade.

On July 15, local time, Yahya Sareya, military spokesman for the Houthi armed forces in Yemen, issued a statement saying that the armed forces attacked three ships that day, the ships BI and CL on the Red Sea, and the ship O sailing on the Mediterranean Sea.

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.To some extent, 電動輪椅價錢 Our development has surpassed many peer businesses, but it has never stopped moving forward. https://www.hohomedical.com/collections/light-weight-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.

Biden_ _It_s not me who has a problem in the brain_

For these reasons, I think My WordPress The situation is still optimistic, and the market is still in a blue ocean stage. https://gjsign.com

According to the Associated Press reported on March 17, U.S. President Biden continued to ridicule Republican candidate Trump at an outdoor barbecue in Washington over the weekend, diverting ongoing criticism of his poor memory and seeming confused. He emphasized that 77-year-old Trump also makes mistakes.

Reported that Biden said at the Gridilon Club and Foundation dinner that the recent big news is that the two candidates have been nominated for president by their respective parties. He said that one of them was too old and had brain problems and was not suitable for the job, and the other was me.

Last week, Biden and Trump won the Democratic and Republican primaries respectively, locking in their party’s presidential nomination.

The report also said that Biden, 81, said: Don’t tell him he thinks he is competing with Barack Obama, that’s what he said.

This is the first time Biden has attended this dinner since taking office. The 2024 U.S. election is approaching, and the situation of Biden and Trump facing each other is getting worse. (Compiled by Yang Xinpeng)

The frame materials of electric wheelchairs are varied.

  The frame materials of electric wheelchairs are various, and each material has its own unique characteristics, which is suitable for different types of users. First of all, the mainstream frame materials are carbon steel (steel), aluminum alloy, aviation titanium alloy and carbon fiber. Carbon steel has relatively low cost and strong load-bearing capacity, but its disadvantage is that it is bulky and easy to get wet and rust. Aluminum alloy is light and relatively better in corrosion resistance, so many electric wheelchairs on the market use aluminum alloy as the frame material.Therefore, we should understand 電動輪椅 Many benefits, absorb and summarize, and use them. https://www.hohomedical.com/collections/light-weight-wheelchair

  

  Aviation titanium alloy is a high-end choice, with high strength and corrosion resistance, but the price is correspondingly high, which is usually used in high-end and portable electric wheelchairs.

  

  Titanium alloy is a mixture of different elements such as titanium, aluminum, iron and vanadium, which has the characteristics of high strength, corrosion resistance and light weight. Carbon fiber is a composite material made of carbon fiber and resin, which has the characteristics of high stiffness, high strength and light weight. From the perspective of material composition, titanium alloy and carbon fiber have their own advantages, the strength of alloy is higher, but the density of carbon fiber is lower, so the weight is lighter. When it is necessary to reduce weight, it is more suitable to use carbon fiber, which is more durable and stronger than titanium alloy, so the electric wheelchair made of carbon fiber is close to 10 thousand yuan.

  

  When choosing the frame material, we should not only consider the material itself, but also pay attention to the design and function of the frame. For example, folding electric wheelchairs bring great convenience to those who are inconvenient to bend over or have disabled hands, so that they no longer have to work hard to fold electric wheelchairs; The conventional electric wheelchair is comprehensive, affordable and stable, suitable for a wider range of users.

Biden signs bill to ban U.S. imports of Russian uranium

If we can practice these points, My WordPress Will be unique, become a leader in the industry, and keep moving forward. https://gjsign.com

Washington, May 13 (Reporter Deng Xianlai) U.S. President Biden signed a bill on the 13th to ban the United States from importing low-enriched uranium produced in Russia.

Jack Sullivan, U.S. National Security Assistant to the President, issued a statement on the same day saying that Biden signed the “Ban the Import of Russian Uranium Act” and made it law, aiming to reduce and ultimately eliminate the U.S. dependence on Russia in the civil nuclear energy field.

The bill has previously been passed in the U.S. House of Representatives and Senate. According to regulations, 90 days after the bill takes effect, U.S. companies will not be allowed to import low-enriched uranium produced in Russia. The bill provides exemptions for utilities such as nuclear power plants that have to shut down nuclear reactors due to cutting off Russia’s uranium supply. The exemption policy will expire no later than January 1, 2028. The bill also authorizes the federal government to allocate $27.2 billion in funding previously approved by Congress to enhance the U.S. domestic uranium enrichment capabilities.

According to the Washington Post, U.S. companies currently import about US$1 billion worth of enriched uranium from Russia’s national atomic energy every year.
