Abstract

The invention relates to electric wheelchairs, comprising a frame, and a seat, front wheels, a rear wheel, a steering control mechanism, a driving device, a speed-adjusting control mechanism as well as a brake mechanism all of which are arranged on the frame, wherein two front wheels with adjustable wheel distance are connected to the front end of the frame; a rear wheel is connected to the rear end of the frame; the rear wheel is used as a driving wheel and driven by the driving device so as to drive the two front wheels to rotate; the rear wheel is connected with a steering rotary shaft of the steering control mechanism through a rear folk assembly, and synchronously rotated with the steering rotary shaft to become a universal wheel; and the seat is arranged on the frame through a lifting mechanism. The invention provides inverted three-wheel type electric wheelchairs, which have the advantages of stability, convenience, flexibility, wide application range, and capability of realizing the functions of adjustable wheel distance of the front wheels, rear wheel driving, rear wheel steering, adjustable seat height and the like.

Description

technical field [0001] The invention relates to an electric wheelchair, in particular to an electric wheelchair for the elderly and the disabled. Background technique [0002] Although existing electric wheelchairs can solve the manpower of pushing wheelchairs to a certain extent, such wheelchairs have high requirements on road surface quality, are easy to lean forward and roll over, and the wheel base cannot be adjusted, especially the height of the seat is not fixed. Change, this greatly limits the range of use of this wheelchair and the user's activity space. Contents of the invention [0003] The purpose of the present invention is to overcome the defects existing in the prior art, and provide a stable, convenient, flexible and wide-ranging inverted three-wheeled electric wheelchair, which can realize adjustable front wheel track, rear wheel drive, and rear wheel drive. Features such as steering and seat height adjustment. [0004] The technical solution adopted by t...
