Wheelchair horizontality regulating mechanism

Abstract

The invention provides a wheelchair horizontality regulating mechanism. The regulating mechanism comprises a gravity center wheel, two crank arm push rods, two connecting lines, and a support shaft, wherein the gravity center wheel and the support shaft are in cross connection, and the gravity center wheel is connected with the two crank arm push rods through the connecting lines. In the regulating mechanism, the gravity center wheel regulation mechanism is used to always keep the stretch force for the vertically downward gravity center when the wheelchair climbs or gets down the stairs; the mobile and stretchable crank arm push rods at the head part allow the front part or the rear part of the seat to be lifted to regulate the horizontality of the wheelchair; and the horizontality regulation of the seat and the stair climbing and getting downstairs of the wheelchair are synchronous, and the regulation amplitude is in proportion to the wheelchair inclination. The invention adopts simple mechanical parts to realize automatic regulation, no additional power is needed for driving, no manual intervention control is needed, and the advantages of low cost, simple structure, and easiness in realization, are achieved.

Description

technical field [0001] The invention relates to the technical field of wheelchairs. In particular, it relates to a mechanism for adjusting the horizontal state of a wheelchair during driving. Background technique [0002] In order to achieve the goal of effectively adjusting and maintaining the level of the wheelchair to achieve the wheelchair going up and down stairs smoothly, there are already many solutions and corresponding wheelchair products at home and abroad. For example, crawler type, planetary wheel type, crank type, eccentric circle type, leg type, and various mixed technology applications. Looking at these wheelchair products, most of them have defects of one kind or another, such as being expensive, bulky, and complicated in structure. Contents of the invention [0003] The purpose of the present invention is to overcome the many deficiencies of the existing ladder wheelchair products in solving the seat level adjustment scheme, and provide a simple structur...
