Electric stair-climbing wheelchair

Abstract

An electric stair-climbing wheelchair is available in nursing type and self-driving type. A track travelling mechanism and a track driving mechanism are disposed on a frame between front wheels and rear wheels. The front wheels are disposed on a seat. The rear wheels are disposed on a rear wheel lifting mechanism. The seat is hinged to the frame. A seat balance mechanism is hinged to a seat support. The rear wheel lifting mechanism is hinged to the frame. A battery module is connected with a track travelling motor, a seat balance motor and a rear wheel lifting motor through a control mechanism. Power output ends of the three motors are connected with the track travelling mechanism, the seat balance mechanism and the rear wheel lifting mechanism through respective transmission mechanisms. The electric stair-climbing wheelchair has the advantages that the self-driving type is added while the nursing type is modified; climbing stairs with rubber tracks is safer; track-aided stair climbing is subjected to stepless speed regulation, and the fear of climbing stairs is eliminated for the disabled; an electric carrier tricycle is specially designed according to the two types, the running speed and distance of the electric carrier tricycle are far beyond those of domestic and overseas like products, and the electric carrier tricycle is low in price and easy to popularize.

Description

technical field The invention relates to an electric stair-climbing wheelchair, which has two models, one is a nursing type, and the other is a self-driving type. The nursing type is used for nursing staff to transport disabled persons, patients and the elderly who cannot walk up and down stairs and to enter and exit various places.

Background technique Prior art is that the patent No. of my invention before is the invention stair-climbing wheelchair of ZL200720103908.0, and its main structure comprises vehicle frame. Foldable seat, front wheel and rear wheel, crawler walking and driving mechanism, seat balance and driving mechanism, rear wheel lifting and driving mechanism, the disadvantages are that the crawler technology is not advanced enough, the foldi...

AI Technical Summary

Problems solved by technology

Foldable seat, front wheel and rear wheel, crawler walking and driving mechanism, seat balance and driving mechanism, rear wheel lifting and driving mechanism, the disadvantages are that the crawler technology is not advanced enough, the folding seat is not practical, and the movable armrest is not enough. It’s easy to use, but the speed of climbing stairs cannot be adjusted, and there is only nursing type, lack of self-driving type
