Disabled person stepping and lifting device of urban bus

Abstract

The invention discloses a disabled person stepping and lifting device of an urban bus. The invention relates to the technical field of disabled person stepping lifting devices and discloses an urban bus disabled person stepping lifting device which comprises a base, the right side of the inner wall of the base is fixedly connected with the right side of a motor, a transmission shaft of the motor is fixedly connected with the right side of a bevel gear A, and the motor is started to drive the bevel gear A to rotate by starting a motor switch. The bevel gear A drives the bevel gear B to rotate,the bevel gear B drives the threaded rod A to rotate, the bolt A starts to move downwards, the bolt A drives the push rod A to move downwards, the push rod A pushes the piston A, the piston A drives the piston B to move leftwards, the piston B pushes the push rod B to drive the rack to move leftwards, and the gear engaged with the rack starts to rotate. The gear drives a bevel gear C to rotate, and the bevel gear C drives a bevel gear D to rotate. The bevel gear D drives the threaded rod B to rotate, the bolt B starts to move leftwards, the connecting rod A is driven to move leftwards so as tosupport the supporting table, and the lifting effect is achieved.

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.

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.
