The invention relates to the technical field of wheelchair equipment, and in particular to a driving device of a double-tooth-group structure for a wheelchair. The driving device comprises a driving arm, wherein a shifting operator is arranged at the top end of the driving arm; a fixed plate is arranged at the bottom end of the driving arm; a metal flexible shaft is arranged in the driving arm; the top end of the metal flexible shaft is connected to the shifting operator, and the bottom end of the metal flexible shaft is connected to a bidirectional clutch assembly; a swinging fork is arrangedon the bidirectional clutch assembly, and the bidirectional clutch assembly is connected to the fixed plate at the bottom end of the driving arm by virtue of the swinging fork, so that a driving rodcomponent is formed. A shifting mechanism is transmitted by virtue of a straight tooth tooth group, and a bevel tooth group mechanism of a bidirectional clutch is delivered by virtue of the metal flexible shaft, so that a double-tooth-group driving mechanism is formed; by virtue of the bevel tooth group mechanism, shifting is controlled, and by virtue of the bidirectional clutch, switching among three gears, namely a forward gear, a neutral gear and a reverse gear, is conducted; and the driving device is simple in structure, and the driving device, which adopts double-tooth-group structure transmission, is smooth in transmission and high in working efficiency.
Description
【Technical field】 [0001] The invention relates to the technical field of wheelchair equipment, in particular to a driving device with a double tooth set structure for a 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: wheelchair frame, wheels, brake device and seat. In order to facilitate the actions of the above-mentioned groups, a driving device is generally installed on an ordinary wheelchair, so that the wheelchair has power and expands the activity radius of the physically disabled and the handicapped. The traditional electric wheelchair has the following problems. The driving device has problems in acceleration and deceleration and the increase...
