Abstract

The invention discloses an electric wheelchair enabling user to lie down. The electric wheelchair comprises a frame. The front part of the frame is hinged with pedals; the back part of the frame is hinged with a back rest; each pedal is formed by a pedal rod and a pedal plate fixed on the lower end of the pedal rod; two pedal rods are fixed on the front parts of the frame; the two pedal rods are arranged on the left and right sides of the frame in a relative way; the upper end of each pedal rod is hinged with and fixed to the frame; a part of the pedal rod deviating from the upper part of the pedal rod is hinged with and fixed to one end of a front electric telescopic device; the other end of the front electric telescopic device is hinged with and fixed to the front part of the frame; a supporting rod is respectively arranged on the left and right sides of the back rest; the back rest is supported on the upper side of the frame via the supporting rods; the lower ends of the supporting rods are both hinged with and fixed to the frame; a part of each supporting rod deviating from the lower end of the supporting rod is hinged with and fixed to one end of a back electric telescopic device; and the other end of the back electric telescopic device is hinged with and fixed to the back part of the frame.

Description

technical field [0001] The invention relates to an electric wheelchair. Background technique [0002] Usually wheelchairs only have one posture: sitting posture. Users cannot change their posture at will after sitting for a long time. The buttocks muscles will be oppressed for a long time, which will lead to blocked blood circulation. Proper lying down can relieve the pressure on the buttocks, thereby reducing the incidence of bedsores. For this reason, wheelchairs with adjustable backrests and footrests have appeared on the market, but their backrests and footrests are linked, so that the wheelchair has only one lying posture. Wheelchairs are not suitable for all users; and the linkage between the backrest and the pedals makes the structure of the wheelchair very complicated and cannot be folded, which is inconvenient for sellers and users to store and store. Contents of the invention [0003] The object of the present invention is to provide a reclining electric wheelch...
