electric wheelchair

An electric wheelchair, in particular an electric wheelchair that is easy for the implementer to control.

The existing wheelchair is driven by a pusher to facilitate the movement of the injured person. However, for the implementer, when the slope is uphill or the road is bumpy, the weight of the wheelchair plus the injury is The implementer needs a considerable amount of effort to assist the injured and is very labor-intensive.

In order to solve the shortcomings of the traditional old wheelchair, an electric wheelchair with a drive motor on both sides of the wheelchair and an external control unit for the wheelchair armrest is born. The electric wheelchair mainly controls the forward direction or speed of the electric wheelchair by the injured person. The advantages of the driver's load are alleviated, but it is only suitable for the patient who can move his hand and have a clear awareness before he can control the movement of the electric wheelchair. The full-time patient or the demented patient still needs the implementer to further assist the implementation. .

However, with the social structure of the elderly population, which is now younger and younger, the phenomenon of elderly care for the elderly is everywhere. For elderly advocates who are physically weak and whose body may have both diseases, the existing electric wheelchairs cannot be alleviated. The physical exertion of the injury is slightly inadvertent in the implementation process, which may cause harm to the implementer and greatly reduce the willingness of the promoter to assist the injured.

In order to solve the current lack of wheelchairs that are friendly to the implementer, the present invention is based on the existing electric wheelchair, and the control module for controlling the direction and speed of the wheelchair is placed on the push handle of the electric wheelchair, and the injured wheelchair cannot control the electric wheelchair. At the time, the proprietor controls the direction and speed of the electric wheelchair to reduce the burden on the promoter to promote the injury and increase the willingness of the promoter to assist the movement of the injury.

To achieve the above objective, an electric wheelchair includes a wheelchair body, a driving motor module and a control module, wherein: the wheelchair body is provided with a wheelchair seat, and the left and right sides of the wheelchair seat are provided a wheelchair armrest, a wheelchair pusher is arranged on the rear side of the wheelchair seat, two steering wheels are arranged on the front side of the bottom of the wheelchair body, and two driving wheels are arranged on the rear side of the bottom of the wheelchair body; the driving motor module is arranged At the bottom of the wheelchair body, the driving motor module is coupled to and drives two driving wheels. The control module is disposed on the wheelchair push handle, and the control module is electrically connected to the driving motor module.

The control module is detachably disposed on the wheelchair push handle.

The control module is provided with a C-shaped ring that can be selectively engaged with the wheelchair pusher or the wheelchair armrest, and a rocker or a directional key is disposed on the C-ring. .

The control module includes an armrest control unit disposed on the wheelchair armrest and a push handle control unit disposed on the wheelchair push handle.

The armrest control unit and the push handle control unit are respectively provided with an electrical socket, and an electric wire is provided, one end of which is connected to the driving motor module, and the other end is provided with one plug selectively coupled with each electrical socket.

As can be seen from the above description, the present invention has the following advantages:

1. The present invention changes the old electric wheelchair that can be controlled by the injured person only. By setting the control module on the push handle of the electric wheelchair, the pusher controls the electric wheelchair, and easily assists the injured person who cannot operate the electric wheelchair by himself. Mobility reduces the burden on promoters, especially those who are old or in poor health.

2. The electric wheelchair of the present invention further detachably mounts the control module on the armrest or the push handle without changing the existing electric wheelchair structure, and the manufacturer does not need to reproduce the electric wheelchair, and the existing electric motor can be used. Wheelchairs are modified to reduce the burden of manufacturing costs.

Referring to FIG. 1 , a first preferred embodiment of the present invention includes a wheelchair body 10 , a drive motor module 17 , and a control module 15 . The wheelchair body 10 is provided with a wheelchair seat for riding. 12, two wheelchair armrests 11 are disposed on two sides of the wheelchair seat 12, two wheelchair pushers 13 are disposed on the rear side of the wheelchair seat 12, and two steering wheels 14 are disposed on the front side of the bottom of the wheelchair body 10, and two driving wheels 19 The driving motor module 17 is disposed on the rear side of the bottom of the wheelchair body 10 The driving motor module 17 is electrically connected to the two driving wheels 19 and the control module 15 , and the control module 15 includes an armrest control unit 15 a disposed on the wheelchair armrest 11 and a The pusher control unit 15b is provided to the wheelchair pusher 13.

The driving motor module 17 is electrically driven by a battery 18 disposed at the bottom of the wheelchair body 10. The control module 15 controls the driving motor module 17 to drive the driving motor module 17 to the bottom of the wheelchair body 10. The driving wheel 19 rotates, and the driving wheel 19 cooperates with the steering wheel 14 to achieve the purpose of changing the direction of the wheelchair body 10 and regulating the traveling speed. When the first preferred embodiment of the present invention is used, the occupant and the implementer can respectively control the travel of the wheelchair body 10 by operating the armrest control unit 15a and the push handle control unit 15b, or can add a selection by The hand control unit 15a or the changeover switch controlled by the pusher control unit 15b selects a user who can manipulate the present invention by controlling the switch.
