Balance stair-climbing wheelchair and stair-climbing method thereof

Abstract

The invention relates to the field of electrically-powered wheelchairs, and particularly discloses a balance stair-climbing wheelchair and a stair-climbing method thereof. The technical problems thatin the prior art, stair-climbing wheelchairs move unstably, have large impact and are expensive are mainly solved. The balance stair-climbing wheelchair is characterized by comprising a mechanical system, a track transmission module, an auxiliary wheel, a control sensor system and a whole machine skeleton mechanism, wherein the mechanical system comprises a chassis arranged on two sides of the balance stair-climbing wheelchair; the track transmission module is symmetrically installed on two sides of the chassis; the auxiliary wheel is arranged at the rear end of the balance stair-climbing wheelchair; the control sensor system is arranged in the mechanical system, and controls movement of the mechanical system in cooperation; and the whole machine skeleton mechanism is arranged above the mechanical system. A wheel-track compound scheme is adopted, the advantages of a wheel mechanism and a track mechanism are fully combined, when the balance stair-climbing wheelchair is used on a flat surface, the track transmission module is put away, the balance stair-climbing wheelchair can run like an ordinary electrically-powered wheelchair, and when the balance stair-climbing wheelchair encounters stairs or barriers, the track transmission module can be put down, so that the balance stair-climbing wheelchair conducts stair-climbing motion or passes over the barriers.

Description

technical field [0001] The invention relates to the field of electric wheelchairs, in particular to a balanced stair climbing wheelchair and a stair climbing method thereof. Background technique [0002] At present, there are a large number of people with disabilities among the elderly, disabled and sick in my country. These people constitute a large number of wheelchair demand groups. The huge demand has promoted the rapid development of my country's wheelchair industry in recent years. A large number of electric wheelchairs and manual wheelchairs have entered thousands of households. million households, improving people's quality of life. [0003] However, no matter whether it is an electric wheelchair or a manual wheelchair, it is difficult to go up stairs. Most people in China still live in multi-storey buildings without elevators. [0004] For this reason, the stair-climbing function of wheelchairs has become an urgent problem to be solved. Relevant manufacturers have i...
