Electric wheelchair

Abstract

The invention discloses an electric wheelchair. The wheelchair comprises a seat structure, a handrail structure, a seat supporting structure, a front pedal structure, a front wheel hanging structure,a chassis structure, a back wheel supporting structure and a table board structure, according to the rotation direction and rotation quantity of a steering wheel, the front wheel hanging structure cancorrespondingly strengthen the hanging hardness of wheels of the corresponding sides singly, and two back wheels can change the driving direction of the wheelchair under the driving of a toothed belt; a front pedal can be lifted and lowered, adjust the inclination angle, and have a foot sole massaging function, the seat supporting structure has three freedoms and can cooperate with a gyroscope for using, and in the running process, a seat can be dynamically adjusted to be flat; the chassis structure has a damping function, the sitting comfort can be improved better when wheels cross barriers,a control panel is integrated on the handrail structure, an overconstrained structure is adopted for making the connection and relative movements between the backrest of the seat and the seat more reliable and more durable, the table board structure can be conveniently used, and an LED display screen and a horn are integrated on the backrest of the seat.

Description

technical field [0001] The invention relates to an electric wheelchair. Background technique [0002] At present, the aging of the global population is particularly prominent, and the development of special disabled groups has brought about the diversified needs of the elderly health industry and the industrial market for special groups.
