Suspension-type gravitational-equilibrium stair climbing vehicle with movable gravity center

Abstract

A suspension-type gravitational-equilibrium stair climbing vehicle with movable gravity center comprises three parts: a travelling part consisting of pieces such as a frame, a front wheel, a rear wheel, a crawler belt and a crawler belt forward-falling preventing device; a gravitational equilibrium part consisting of pieces such as a suspending hanging bracket, a sliding sleeve and a battery and self weight of a person; and a seat moving part consisting of pieces such as a sliding seat, a sliding bar and a connection rod. The suspension-type gravitational-equilibrium stair climbing vehicle with movable gravity center has the advantages that in the processes of facing the front to go upstairs and go downstairs, the suspending hanging bracket is mounted in a center hole of the frame, and gravity is utilized to equilibrate. An angle formed in the processes of going upstairs and going downstairs is utilized to pull an eccentric shaft on the frame, the eccentric shaft is connected with one end of the connection rod, the other end of the connection rod pulls the seat on the sliding bar, and the gravity center is moved forwards in the process of going upstairs and is moved backwards in the process of going downstairs to keep the gravity center of the seat being at the center of the vehicle. The suspension type stair climbing vehicle is simple in structure, low in cost, small in turning radius and capable of being controlled via remote control and programs and rotating by 360 degrees in situ. By the aid of the suspension type stair climbing vehicle, the problem that part of riders need companies is solved, and a company can go together by means of operating on an auxiliary seat. In addition, a vehicular basket can carry goods.

Description

technical field [0001] The present invention is an electric stair-climbing vehicle. Specifically, it uses dual motors to be controlled by the handicapped and the accompanying personnel of the patient. kinds of vehicles. Background technique [0002] Existing stair climbing vehicles are generally hidden under the vehicle by a planetary wheel structure or crawlers and are only used when going up and down stairs. Under the dragging of the auxiliary personnel, the front goes downstairs, while the upstairs is the back, and the auxiliary personnel need to go up the stairs backwards. It is very inconvenient to keep looking backwards, and it is easy to hurt people if the electric car is still walking upwards without falling down. Turning and walking on level ground require the assistance of auxiliary personnel. The electric power of the so-called electric stair climber only plays an auxiliary role, and it must be accompanied by specialized personnel, and only one person can take it...
