Problems solved by technology

[0002] At present, there are many types of wheelchairs on the market, such as folding type, stair-climbing type, etc., which provide convenience for people with physical disabilities, but no matter which type of wheelchair, it is impossible to cross the relatively high obstacles on the road, or to walk on the road. It is difficult to maintain balance when climbing over obstacles, especially in complex situations such as climbing stairs and boarding a bus, and there is a high risk of the wheelchair tipping over due to unstable center of gravity

Abstract

The invention discloses a self-adaption wheelchair for moving up and down stairs. A seat is rotatably arranged on a chassis through a supporting rod, multiple crawler wheels are arranged on the chassis and driven by a first motor and can roll over steps or obstacles, and a servo control system controls a second motor to rotate according to data which is collected by an acceleration sensor and a gyroscope; the second motor drives a lead screw support to move in the axial direction, the lead screw support drives the supporting rod to rotate around a bottom rotation shaft and then drives the seatto rotate, and when the wheelchair moves up the steps, the lead screw support moves toward the front portion of the wheelchair and controls the seat to stay in a horizontal state, and the danger is avoided that the wheelchair overturns backward; when the wheelchair moves down the steps, the lead screw support moves toward the back portion of the wheelchair and controls the seat to stay in a horizontal state, the danger that the wheelchair overturns forward is avoided, and accordingly the stability of the wheelchair for moving up and down stairs is improved.

Description

technical field [0001] The invention relates to the technical field of wheelchairs, in particular to an adaptive wheelchair for going up and down stairs. Background technique [0002] At present, there are many types of wheelchairs on the market, such as folding type, stair-climbing type, etc., which provide convenience for people with physical disabilities, but no matter which type of wheelchair, it is impossible to cross the relatively high obstacles on the road, or to walk on the road. It is difficult to maintain balance when climbing over obstacles, especially in complex situations such as climbing stairs and boarding a bus. It is very likely that the wheelchair will tip over due to an unstable center of gravity. Contents of the invention [0003] In order to solve the technical problems existing in the background technology, the present invention proposes an adaptive wheelchair for going up and down stairs. [0004] A kind of self-adaptive stair-climbing wheelchair p...
