Wheelchair steering gear for elevator for the disabled

Abstract

The invention relates to a wheelchair steering gear for an elevator for the disabled, belonging to the field of reversing equipment. The wheelchair steering gear is composed of a support plate, a screw, a spring, a support plate, a spherical washer, a nut, a pressure plate, an L-shaped lever, a support block, a plunger, a piston rod, a cylinder, a motor, a coupling, a bottom plate, a single chip microcomputer, a power source, an air compressor, a top plate, a rotating shaft, a bearing and a switch. The device adopts pneumatic transmission to realize tire tightening, and uses air as medium, which is inexhaustible, convenient in source, directly discharged after use, and does not pollute the environment. A sound insulation layer is installed on the lower surface of the top plate, which can reduce the influence of the noise of the air compressor on the personnel.; Wheelchair steering is driven by an electric motor so that the wheelchair can be pushed away directly from the elevator door,thereby avoiding the problem of inconvenience of wheelchair steering for the disabled and the potential safety hazard brought about by wheelchair collapse and personnel mobility. Nuts and spherical washers are designed to better accommodate wheelchairs of different sizes.

Description

technical field [0001] The invention relates to a wheelchair steering device for an elevator for the disabled. Specifically, it adopts a special clamping mechanism and relies on a single-chip microcomputer to control the operation of the whole device, which belongs to the field of reversing equipment. Background technique [0002] The existing elevators fail to fully consider the actual needs of disabled people in wheelchairs. Even if the elevators are special for disabled people, it is difficult for disabled people in wheelchairs to turn around after entering the elevator. Usually, they need to enter the elevator from the front and then turn their heads and look backward slowly. There are great potential safety hazards in this process, especially in densely populated places, where the safety of the disabled is difficult to be effectively guaranteed.
