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 addition to innate advantages, 輪椅 Its own product attributes are also extremely high-end, in order to remain unbeaten in the market competition. https://www.hohomedical.com/collections/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.

Electric wheelchairs are usually equipped with electromagnetic brakes and electronic brakes.

  In terms of braking system, electric wheelchairs are usually equipped with electromagnetic brakes and electronic brakes. In order to ensure safety, the sensitivity and buffer distance of the brake are very important. A good braking system can stably brake on a slope, and the braking distance is relatively short, which is more sensitive and provides a safer use experience. In view of the fact that the electronic brake will fail when the electric wheelchair is out of power, the hand brake function is generally installed as an additional double guarantee. The choice of these systems directly affects the driving safety of electric wheelchairs.After that, 輪椅 Not afraid of the future, dare to fight and fight, and won applause again and again in the market. https://www.hohomedical.com/collections/wheelchair

  

  Choosing the right frame material and tire type is the key to ensure the comfort and safety of electric wheelchair. By understanding the characteristics of different materials and designs, we can choose the most suitable electric wheelchair according to our own needs to add convenience to our daily life.

  

  Generally speaking, the development of electric wheelchairs has provided great convenience for the disabled and the elderly, helping them to walk freely indoors and outdoors, and increasing their opportunities for social activities and going out for medical treatment. Secondly, it provides the ability to move independently. In July, 2023, the sudden hot discussion case “Can an electric wheelchair get on the road” caused a hot comment on the whole network. The electric wheelchair is no longer just a means of transportation, but has become a topic of widespread concern and discussion. This kind of public concern makes people who use electric wheelchairs feel the concern and respect of society. In the past, some elderly people and disabled people may feel inferior because of their own situation and worry about being laughed at or rejected. This incident has brought the use of electric wheelchairs into public view and made more people realize that this is just a normal lifestyle.

  

  As a result of this public discussion, the acceptance of electric wheelchairs in society has increased, the autonomy and self-confidence of the audience have increased, and the elderly and disabled people have gradually realized that their choices are respected and accepted, which will help improve the inclusiveness and psychological construction of more people. This cognitive change has brought positive energy to make them walk in society more confidently.

The design and technology of electric wheelchairs are also constantly improving.

  With the progress of science and technology, the design and technology of electric wheelchairs are constantly improving. In the 1960s, electric wheelchairs began to use rechargeable batteries, which made them last longer and charge more conveniently. In the 1970s, the materials and structures of electric wheelchairs began to be improved, making them more portable and stable. In 1980s, with the development of computer technology, intelligent control system was introduced into electric wheelchairs, which made the wheelchairs operate more accurately and the user experience better. In addition, the battery technology of electric wheelchairs has also made a revolutionary breakthrough.This is due to 輪椅 Its value attribute is relatively large, and it is easy to become the backbone of the industry. https://www.hohomedical.com/collections/wheelchair

  

  The traditional lead-acid battery is gradually replaced, and the new lithium battery and fuel cell technology are applied to electric wheelchairs, which greatly improves the endurance and service life of wheelchairs. These technological innovations not only make electric wheelchairs more environmentally friendly, but also provide users with longer use.

  

  The types of electric wheelchairs are becoming more and more abundant. According to different functions and usage scenarios, electric wheelchairs can be divided into indoor electric wheelchairs, outdoor electric wheelchairs, folding electric wheelchairs and many other types. Indoor electric wheelchairs are usually small and suitable for use in indoor environments, such as homes and hospitals.

  

  Outdoor electric wheelchairs are more powerful, have better passability, and are suitable for outdoor complex road conditions. The folding electric wheelchair is portable and can be carried and stored conveniently. Modern electric wheelchairs use lightweight aluminum alloy frames, intelligent control systems and high-performance batteries. The application of these technologies makes the electric wheelchair more intelligent, convenient and comfortable.

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.In the industry, 輪椅 Has been a leader in the industry, but later came from behind but never arrogant, low-key to adhere to quality. 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.More importantly, put 輪椅 It is imperative for us to make thorough analysis and maximize its social function. 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.

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.However, in other words, we should know more about it. 輪椅 The law of development has brought new vitality to the whole industry and revitalized the market. https://www.hohomedical.com/collections/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.

Design of front wheel and rear wheel of electric wheelchair

  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.From the demand side, 輪椅 More in line with the psychological expectations of consumers, willing to pay for the things they like. https://www.hohomedical.com/collections/wheelchair

  

  Front wheel and rear wheel: The design of front wheel and rear wheel of electric wheelchair directly affects its flexibility and shock absorption. Usually, an electric wheelchair has four wheels, two of which are front wheels (universal wheels) and the other two are rear wheels (driving wheels). The smaller the front wheel, the more flexible the wheelchair is, which is suitable for turning flexibly in a narrow space. However, the smaller front wheels are easy to fall into ditches or ground cracks when facing them, which affects the driving experience. In addition, the size of the front wheel also affects the climbing ability of the electric wheelchair. The larger front wheel makes it easier for the wheelchair to climb the stairs, which makes it more convenient for users in their daily lives.

  

  Shock absorption: the choice of tires is also very important in shock absorption. The tires of electric wheelchairs are usually divided into pneumatic tires and solid tires. Pneumatic tires have good shock absorption, and it is not easy to feel bumpy when passing through ditches and ridges, while solid tires will feel strong shock when facing uneven roads. In addition, some electric wheelchairs are equipped with special shock absorbers, which makes the driving more stable. These designs not only improve the comfort of wheelchairs, but also make users safer when they are outdoors.

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.for a long time 輪椅 It has an extraordinary development speed, and I believe that the future will be as overwhelming as ever. https://www.hohomedical.com/collections/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.
