electric stair climbing wheelchair

Abstract

The invention discloses an electric stair climbing wheelchair; in applications of climbing up or sliding down a stair, climbing slide shoes make contacts with an intersection line between a horizontal plane and a vertical plane of a stair step; an electric drive unit fixed on the stair climbing wheelchair allows climbing slide guide plates to slide on the climbing slide shoes; the whole stair climbing wheelchair uses a stair step intersection point as a support for rotation; motions can be combined to form an oblique upward motion or an oblique downward motion; the wheelchair support body can transfer between the climbing slide shoes and large wheels, so the stair climbing wheelchair can continuously go up or go down, thus finishing climbing work and providing the stair climbing function. The electric stair climbing wheelchair is excellent in stair climbing performance, stable in motions, small in impact, laborsaving, simple in structure, and convenient in usage.

Description

technical field [0001] The invention relates to an electric appliance with the function of climbing stairs, in particular to an electric wheelchair for climbing stairs. 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 human wheelchairs have entered thousands of households. million households, improving people's quality of life. However, no matter whether it is an electric wheelchair or a manual wheelchair, it is difficult to go up stairs, and most people in China still live in multi-storey buildings without elevators, and they rely on stairs to go up and down, which restricts the promotion of wheelchairs to a certain extent. For this reason, the stair-climbing functio...

Problems solved by technology

However, no matter whether it is an electric wheelchair or a manual wheelchair, it is difficult to go up the stairs. However, most people in China still live in multi-storey buildings without elevators.

For this reason, the stair-climbing function of wheelchairs has become an urgent problem to be solved. Relevant manufacturers have invested a lot of manpower and material resources in research and development. At present, there are many wheelchairs with electric stair-climbing functions. Among them, the structure of the electric star-wheel stair-climbing wheelchair is relatively simple, but this This type of wheelchair has great defects, such as unstable movement and large impact; while the stair-climbing technology of the all-wheel seat self-balancing stair-climbing wheelchair and the movable support rod stair-climbing wheelchair produced by foreign imported technology is relatively mature, but the price is expensive.
