They can go to the supermarket to purchase by themselves and no longer rely on the help of others.According to professional reports, 電動輪椅 There will be a great period of growth, and the market business is constantly expanding, and it will definitely become bigger and bigger in the future. https://www.hohomedical.com/collections/light-weight-wheelchair

　　For the disabled and the elderly, it brings a wider world, embarks on the journey of travel, visits places of interest, and feels the cultural atmosphere of different cities.

　　The popularity of electric wheelchairs has also improved the quality of life of disabled people. Traditional manual wheelchairs require users to push hard, which easily leads to muscle fatigue and bone problems. However, the electric wheelchair can easily move without the user’s effort, just by lightly operating the joystick or button, which reduces the physical burden of the user and improves the convenience of life.

　　In addition, electric wheelchairs have also promoted social concern and care for the disabled. With the popularity of electric wheelchairs, the needs and rights of the disabled in society have also received more attention. Many public places and means of transportation have also been transformed with barrier-free facilities, which makes it easier for disabled people to enter all fields of social life.

　　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.In the long run, 電動輪椅價錢 The value will be higher and higher, and there will be a great leap in essence. 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.

　　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 order to open the market, 電動輪椅 Constantly improve the ability of business development and create an extraordinary brand image for it. https://www.hohomedical.com/collections/light-weight-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.

　　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.Through bit by bit efforts, let 電動輪椅價錢 Our market share is getting higher and higher, and the return on investment is also rising steadily. 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.

　　Brushless motor and brush motor have their own advantages and disadvantages, and the specific choice of motor should be decided according to actual needs.among 電動輪椅價錢 It has given great spiritual support to entrepreneurs, and more entrepreneurs will contribute to this industry in the future. 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.

　　The chemical formula for nitric acid is HNO3. Anhydrous pure nitric acid is a colorless liquid that easily decomposes into nitrogen dioxide, resulting in a reddish brown color.In the past ten years, Chemical filter Defeated many competitors, courageously advanced in the struggle, and polished many good products for customers. http://www.luoyuan108.com/

　　Many chemical users need to choose nitric acid pumps. So, how should nitric acid pumps be selected and which pump is better? Firstly, when transporting nitric acid, it is necessary to understand the characteristics, temperature, concentration, density, and equipment conditions of nitric acid, and then choose the corresponding pump type. Usually, nitric acid pumps can use 304 or 316L, but nitric acid reacts with metals. For the sake of service life, it is recommended to use fluoroplastic magnetic pumps. Of course, fluoroplastic centrifugal pumps can also be used. Generally, we recommend choosing magnetic pumps, which are fully enclosed, without shaft seals, and have the advantage of no leakage.

　　It should be noted that nitric acid has swelling properties for most rubber and fluororubber. Therefore, it is recommended to use expanded PTFE or pure PTFE for the auxiliary static seal of the pump (due to the hardness of pure PTFE, the sealing surface of nitric acid pumps often cannot be tightly compressed, so it is recommended to use soft PTFE).
