Introduction to Electric Wheelchair
With the progress of society, disabled people are more eager to return to the society and live independently, which promotes the continuous improvement and improvement of the performance and quality of wheelchairs. It is a typical example, some advanced electric wheelchairs use a lot of high-tech. Wheelchair Network introduces the function and structure of electric wheelchairs in detail.
The electric wheelchair is used when the patient’s hand function is very weak and cannot drive the ordinary wheelchair, or although it can be driven, but the walking distance is long, the physical strength cannot bear it, or when the body is weak and cannot be driven at all.
The structure of the electric wheelchair is far more complicated than that of the ordinary wheelchair. It mainly includes the following mechanisms:
1. Drive mechanism Powered by 12V or 24V battery, there are front-wheel drive and rear-wheel drive. Front-wheel drive is easy to jump over obstacles.
2. Transmission mechanism There are two types: step-by-step speed change and stepless speed change.
3. Brake mechanism Most of them use the function of motor reversal.
4. Battery Use a 24V car battery, which can be used for 3 to 6 hours on a single charge.
5. Control mechanism There are hand control, head control, tongue control, cheek control, chin control, air control, voice control, etc. In addition to manual control, the other various controls are used for quadriplegic patients. C4 and below injuries, when the respiratory muscles still function, try to use air control. For injuries above C4, the respiratory function is poor, and control methods such as head, tongue, cheek, chin, and voice control can be used, but chin control is the most common.
