Problems solved by technology

Whether it is going up or down the stairs, the motor must be started once, which will generate a large current impact on the motor and the battery, which will affect the battery and the service life of the motor.
In order to facilitate the operation of going up and down stairs, the handrails are made relatively long, which is very inconvenient when pushing on ordinary roads

Abstract

The invention provides an energy-saving A type auxiliary electric stair-climbing wheel chair comprising a wheel chair rack, universal wheels, back wheels, a seat chair, seat chair armrests, a power supply switch, a storage battery, a motor, a decelerator, a pedal plate, pedal plate supporting rods, a pedal plate adjusting plate, a landing rack, a controllable air spring combination slow-descending device, a guide wheel, a ratchet combination safety self-locking device, a foldable lengthened armrest device, a double crank linking positioning support rod device and a clutch combination device. The beneficial effects are that the energy-saving A type auxiliary electric stair-climbing wheel chair is simply structured and possesses light weight; the wheel chair can safely and stably come downstairs without help of any power, so energy use can be reduced by 50%; no noise can be caused and environment protection can be achieved; motor starting times can be reduced and current impact to the motor and the storage battery can be reduced, so service life of the motor and the storage battery can be prolonged; and the wheel chair can be flexibly and conveniently pushed on common road surfaces.

Description

Technical field: [0001] The invention belongs to auxiliary vehicles, in particular to an energy-saving A-type auxiliary electric stair climbing wheelchair. Background technique: [0002] At present, all kinds of electric stair-climbing wheelchairs produced in China must use power to go up and down stairs no matter what form they adopt. Going downstairs adopts the reverse operation of going upstairs, which wastes energy and generates noise, which is not conducive to environmental protection. When going downstairs, the operator must pull back hard to ensure that the wheelchair will not roll forward freely. Once the operation is wrong, the person will roll over and cause an accident. There is no safety guarantee. Whether it is going up or down the stairs, the motor must be started once, which will generate a large current impact on the motor and the battery, which will affect the service life of the battery and the motor. For the convenience of going up and down the stairs, t...
