Embodiment 2

[0052] In this embodiment, on the basis of the above-mentioned embodiment 1, the driving wheel is replaced by a gear, and the wheel hub side of the wheel is fixedly provided with an external gear ring extending in a direction parallel to its axis, and the gear and the external gear ring engage. The driving wheel will not cause wear to the tread of the wheel, prolonging the service life of the tire. In the forward direction A, the drive wheel 10 is instead arranged on the upper side of the wheel 5 . In this embodiment, the speed regulating device 3 is replaced at the hand-holding position of the vehicle frame 1 . In the electric wheelchair described in this embodiment, there are two wheels 5 symmetrically arranged on both sides of the vehicle frame 1 , and the motor 6 jointly drives the two driving wheels 10 .

[0053] The wheel driving devices in the above embodiments can be produced separately and configured on the wheels that need to be driven,

Abstract

The invention relates to a wheel driving device and a wheelchair, in particular to a wheel driving device and an electric wheelchair. The wheel driving device comprises a driving wheel and a motor fordriving the driving wheel to rotate, and the driving wheel is in detachable driving connection with a wheel. The device solves the technical problems that when an equipment battery of a driving wheelin the prior art is out of power, manual pushing resistance is large and pushing wastes efforts. The wheel driving device and the wheelchair provided with the same are further provided. The wheel driving device electrically drives the wheel when there is power and makes riding or pushing need less efforts when the battery is out of power.

Description

technical field [0001] The invention relates to a wheel driving device and a wheelchair. Specifically, it relates to a wheel driving device and an electric wheelchair. Background technique [0002] Wheelchair is an important tool for rehabilitation. It is not only a means of transportation for physically disabled and handicapped people, but more importantly, it enables them to perform physical exercises and participate in social activities with the help of wheelchairs. Ordinary wheelchairs are generally composed of four parts: frame, wheels, brakes and seat. [0003] Electric wheelchairs in the prior art are based on ordinary wheelchairs, and an electronic power assist system is added to reduce the physical exertion of users. For example, Chinese patent document CN202490112U discloses a portable folding electric wheelchair, which includes a folding chassis, a seat frame, a motor, a lithium battery, a direction console, a seat, and a driving wheel, wherein the motor is inst...
