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.At first, 電動輪椅 It developed out of control and gradually opened up a sky of its own. https://www.hohomedical.com/collections/light-weight-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 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.For the immediate pressure, 電動輪椅 With its own coping style, it can break the predicament and usher in a new life through the quality of the product itself. https://www.hohomedical.com/collections/light-weight-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.

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.If we can practice these points, 電動輪椅 Will be unique, become a leader in the industry, and keep moving forward. https://www.hohomedical.com/collections/light-weight-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.

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.In the eyes of peers, 電動輪椅價錢 It has good qualities that people covet, and it also has many loyal fans that people envy. 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 future of electric wheelchair will be more intelligent and convenient.

  A simple example is similar to the behavior of “wearing a mask” in the past, which will be called strange. Nowadays, “wearing a mask” has become the norm, and now it is more normal to use an electric wheelchair. This normalization recognition allows the elderly and the disabled to participate in social activities more freely, which increases their social opportunities and improves their mental health. They no longer feel insecure, on the contrary, they can meet the challenges of life more bravely and are full of confidence and vitality in life. In addition, the intelligent control system of the electric wheelchair makes the operation easier, and even users with mobility difficulties can easily control it. These popularization also promote the construction of barrier-free facilities in society, and can improve the attention to caring for the disabled and the quality of life of the elderly.more importantly, 電動輪椅價錢 Made a fighter in the product, not afraid of any competitor’s attack. https://www.hohomedical.com/collections/light-weight-wheelchair

  

  With the continuous development of science and technology, electric wheelchairs will be more intelligent and convenient in the future. Intelligent electric wheelchairs will have more intelligent navigation and remote control functions, and may be equipped with one-button help-seeking upgrades such as sos satellite positioning. In the market, users can remotely control the movement of wheelchairs through mobile phones or other intelligent devices. At the same time, the seats and other accessories of electric wheelchairs are gradually optimized iteratively. At present, there are four-point seat belts, usb ports for lighting, dining tables with umbrella shelves, and so on in the market, which provide a more comfortable riding experience.

  

  Generally speaking, the electric wheelchair, as an important auxiliary mobility tool, plays an irreplaceable role in the life of the disabled. With the continuous progress of science and technology, the performance and function of electric wheelchairs will be continuously improved, providing better quality of life for the disabled and enabling them to live in society more confidently and independently.

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.At the same time, 電動輪椅 It is no longer a relatively unfamiliar industry, and it enters the public’s sight more and more frequently, gaining more attention and recognition. 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.

Modern electric wheelchairs usually use lithium batteries as power supply.

  It is the energy source of electric wheelchairs, which can be divided into lead-acid batteries and lithium batteries. The voltage of electric wheelchairs is generally 24v. The different ah capacity of batteries directly affects the overall weight, endurance and service life of wheelchairs. With the continuous development of lithium battery technology, modern electric wheelchairs usually use lithium batteries as the power source.The above conclusions show that 電動輪椅價錢 To a great extent, it can bring new vitality to the market and make the industry develop well. https://www.hohomedical.com/collections/light-weight-wheelchair

  

  Lithium batteries have the advantages of high energy density, light weight and fast charging speed, which can provide a longer cruising range. There are also 6AH lithium batteries in the market that meet the standards of air boarding. People with disabilities and mobility difficulties can travel with portable electric wheelchairs and batteries.

  

  If the 20ah lead-acid battery is compared with the 20ah lithium battery, the lithium battery has a lighter weight and a longer battery life, and the life of the lithium battery is relatively long, about twice the life of the lead-acid battery, but the cost of lithium battery will be higher. Lead acid, on the other hand, is relatively more economical, and there are many after-sales points of electric vehicles under the domestic battery brands such as Chaowei, which is convenient for maintaining batteries and replacing carbon brushes, and can meet the needs of users for long-term use.

  

  At present, lithium battery electric wheelchairs are mainly used in portable electric wheelchairs, which are relatively inferior to lead-acid in battery life. The later replacement cost is also high. Here, you can refer to the approximate cruising range of the battery collected by Xiaobian. The battery life will be different due to different road conditions, different people’s weights and continuous exercise time.
