Abstract

The invention relates to a folding electric wheelchair, aiming at solving the problems that in the prior art, the structural stability of the product is poor, the operability is poor, and the potential safety hazards are high. The folding electric wheelchair comprises a wheelchair bracket, the wheelchair bracket comprises a backrest frame, the backrest frame comprises a connecting part and a supporting part, and the folding electric wheelchair further comprises a seat frame, front wheel carriers and lower connecting rods; the supporting part, the seat frame, the front wheel carriers and the lower connecting rods are connected end to end in sequence to form parallelogram rod groups on two sides of the wheelchair, middle support rods are horizontally mounted at the nodes of the parallelogramrod groups on two sides, telescopic diagonal rods for maintaining the stability of the quadrilateral structure are further mounted at the positions of the diagonal lines of the parallelogram, and twoends of the telescopic diagonal rods are mounted on the corresponding middle support rods. The folding electric wheelchair has the advantages that the wheelchair realizing relatively independent functions and being convenient to fold is obtained, a series of mechanisms convenient for integral adjustment and self-locking are mounted on the wheelchair, while the stability of the whole machine is not influenced, the integral quality of the product is improved.

Description

technical field [0001] The invention relates to the field of auxiliary medical equipment, in particular to a folding electric wheelchair. Background technique [0002] Ordinary wheelchairs are generally composed of four parts: wheelchair frame, wheels, brake device and seat. On the basis of ordinary wheelchairs, hand-operated wheelchairs are equipped with hand-operated devices. On the basis of ordinary wheelchairs, electric wheelchairs add an electronic power assist system to reduce the physical exertion of users. On the basis of electric wheelchairs, intelligent wheelchairs have added positioning movement, standing movement, remote control movement and related Internet + assisted living. It is not only a means of transportation for physically disabled and handicapped people, but more importantly, it enables them to exercise and participate in social activities with the help of wheelchairs. [0003] Foldable wheelchair is one of the common types of wheelchairs. Its main f...
