Electric wheelchair with step climbing function

Abstract

The invention provides an electric wheelchair with a step climbing function. The electric wheelchair comprises a chair body and a front supporting mechanism, wherein a driving shaft is inserted between rear wheels of the chair body in a penetrating mode, the driving shaft is further in transmission connection with a transition shaft through a chain, the front supporting mechanism comprises an upper transverse rod, an electric supporting push rod and a lower transverse rod, the two ends of the upper transverse rod are fixedly connected with the inner side of the bottom of a frame of the chair body respectively, a vertical insertion cylinder is vertically inserted in the middle of the upper transverse rod in a penetrating mode, the electric supporting push rod is inserted into the vertical insertion cylinder in a penetrating mode, a telescopic part at the lower end of the electric supporting push rod is rotationally connected with the middle of the lower transverse rod, and a front protection structure is further connected to the frame at the front end of a cushion of the chair body. The front step-climbing wheel set is put down and makes contact with the ground by controlling the electric supporting push rod, the front side end of the electric wheelchair is supported, adjustment is conducted through the electric adjusting push rod, the inclination of the whole climbing belt and an outer baffle frame is consistent with that of the whole step, the chair body is more stable when going up and down the step, and the overturning phenomenon is avoided.

Description

technical field [0001] The invention belongs to the technical field of electric wheelchairs, and more specifically relates to an electric wheelchair with the function of climbing steps. Background technique [0002] Wheelchair is an important tool for rehabilitation. It is not only a means of transportation for physically disabled and handicapped people, but more importantly, it enables them to use wheelchairs to perform physical exercises and participate in social activities. Electric wheelchairs are based on traditional manual wheelchairs. , Superimposed high-performance power drive device, intelligent control device, battery and other components, transformed and upgraded. [0003] For example, in the patent with the application number: CN202010427671.1, an electric folding wheelchair capable of going up and down steps is disclosed. The wheelchair seat assembly is mounted on the upper part of the wheelchair chassis assembly in a liftable manner through the wheelchair seat ...

AI Technical Summary

Problems solved by technology

[0004] Based on the above, when the traditional wheelchair is going up and down the steps, the moving wheel on the front side leaves the ground, lacks a supporting structure, and is prone to overturning, and in the process of climbing the steps, the front side also lacks a protective structure. Overturning, the patient is easily thrown from the wheelchair, causing injury
