Abstract

The invention relates to a power wheelchair, comprising a seat part, a running mechanism and a control unit which is positioned between the seat part and the running mechanism. The running mechanism comprises a plurality of chair wheels to realize the displacement of the power wheelchair. The chair wheels are macnum wheels, each of which comprises a wheel body with a circle in the center and a plurality of rollers positioned at the periphery of the wheel body, the axes in the center of each roller and in the center of the wheel body form an acute angle; the running mechanism also comprises a plurality of driver motors corresponding to the macnum wheels respectively, the control unit is electrically connected with the driver motor, receives the operation signals of the wheelchair from the outside and converts the operation signals into command signals; the command signals are output to the driver motor; each macnum wheel is driven independently in a way that the control unit drives the motor. The power wheelchair can respectively drive a plurality of the macnum wheels independently in a way that the macnum wheels can change direction during the process of rotation, thus realizing omnibearing rotation.

Description

technical field [0001] The invention relates to an electric wheelchair, in particular to an electric wheelchair capable of omnidirectional movement. Background technique [0002] In recent years, due to the development and changes of the social structure, the total fertility rate has continued to decline, and the domestic population structure has become aging. Some elderly people have reduced neuromuscular function and motor function, and some people with physical disabilities have musculoskeletal function. Nerve damage requires a lot of relying on wheelchairs for transportation. [0003] At present, the common wheelchair structure can be mainly divided into two types: manual wheelchair and electric wheelchair. Among them, the electric wheelchair can provide more comfortable and convenient mobility assistance for the elderly or people with limited mobility, and is easy to operate. It also provides better climbing force and braking force when used on slopes, so as to provide...
