Stepping lifting device for disabled persons in city bus

Abstract

The invention discloses a stepping lifting device for the handicapped on a city bus, which relates to the technical field of stepping lifting devices for the disabled. The right side of the helical gear A is fixedly connected. By starting the motor switch, the motor starts to drive the helical gear A to rotate. The helical gear A drives the helical gear B to rotate. Push rod A moves down, push rod A pushes piston A, piston A drives piston B to move to the left, piston B pushes push rod B to drive the rack to move to the left, the gear meshing with the rack starts to rotate, and the gear drives the helical gear C Turning, the helical gear C drives the helical gear D to rotate, the helical gear D drives the threaded rod B to rotate, the bolt B starts to move to the left, and drives the connecting rod A to move to the left to prop up the support platform and achieve the effect of lifting.

Description

technical field [0001] The invention relates to the technical field of stepping lifting devices, in particular to a stepping lifting device for disabled persons in city buses. Background technique [0002] Since the current large buses pay more and more attention to the convenience and comfort of use, and have gradually required to improve the humanization of products, most bus companies are equipped with movable steps for the disabled in the complete vehicle products. At present, most of the movable steps for the disabled are pull-type and flip-type structures. This type of movable step is to add a barrier-free slope from the body to facilitate the passage of the disabled. This type of step is simple in structure, but laborious and cumbersome to operate Special personnel are required to operate on a special trip, and the passability of wheelchairs for the disabled is poor and difficult to operate. Contents of the invention [0003] (1) Solved technical problems [0004]...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a step lifting device for the handicapped in a city bus, which solves the problem that most of the active steps of the handicapped at present are pull-out and overturning structures. Barrier-free slopes are added on the body to facilitate the passage of the disabled. This type of stepping structure is simple, but the operation is laborious and cumbersome, and generally requires a special person to operate it. The passability of wheelchairs for the disabled is poor and the operation is difficult.
