A barrier-free electric wheelchair

Abstract

The invention provides a barrier-free electrically propelled wheelchair, which comprises a bottom plate, a seat part, a moving part, a driving part, a control part, an angle sensing device and a power supply part, wherein the bottom plate consists of a front bottom plate and a rear bottom plate which are rotatably connected; the seat part is located on the front bottom plate; the moving part consists of front wheels and rear wheels; the driving part is used for driving the front wheels and the rear wheels to rotate; the control part is used for controlling the driving part; the angle sensing device is connected with the driving part; the power supply part is used for supplying power for the electrically propelled wheelchair. As a gear-shaped structure is adopted by the front wheels of the barrier-free electrically propelled wheelchair provided by the invention, the barrier-free electrically propelled wheelchair can be better suitable for transition between the flat ground and stairs; a crawler wheel structure is adopted by the rear wheels, so transition between the stairs and the flat ground can be realized very well, and the barrier-free electrically propelled wheelchair can smoothly move up and down on the stairs; meanwhile, an angle between the rear bottom plate and the front bottom plate can be adjusted according to the actual situation, the barrier-free electrically propelled wheelchair provided by the invention not only is suitable for moving upstairs and downstairs but also is suitable for other ground configurations.
