Abstract

The invention discloses a stair climbing wheelchair capable of crossing obstacles. The stair climbing wheelchair comprises a chair part, a switching mechanism and an auxiliary standing mechanism, wherein the switching mechanism is arranged below the chair part, and is used for switching between roller transmission and the crawler wheel transmission of the stair climbing wheelchair capable of crossing obstacles; the crawler wheel transmission is provided with a first crawler wheel and a second crawler wheel which are connected with each other through a connecting bracket; and the auxiliary standing mechanism is arranged on the lower side of the chair part, and is used for assisting a user in standing. In the horizontal moving process of the stair climbing wheelchair capable of crossing obstacles, the first crawler wheel is positioned in front of the second crawler wheel; and in a stair climbing process, the second crawler wheel is positioned in front of the first crawler wheel. Due to the adoption of the stair climbing wheelchair capable of crossing obstacles, switching between roller transmission and crawler wheel transmission can be realized; and meanwhile, the auxiliary standing mechanism is used for assisting a user in standing, so that the safety and comfort of the stair climbing wheelchair capable of crossing obstacles are enhanced, and the ascending, descending and obstacle crossing stability is ensured.

Description

technical field [0001] The invention relates to the technical field of machinery and control, in particular to an obstacle-climbing wheelchair and a control method for going up and down stairs. Background technique [0002] Wheelchairs are an indispensable means of transportation for the elderly and infirm. But, traditional wheelchair just can't cross when encountering hurdle. Among them, going up and down stairs is the biggest obstacle for these people with disabilities. In 200, the country considered installing elevators for these houses in order to solve the problem of going up and down stairs in these houses, but due to various reasons, the plan was shelved. [0003] At present, the way to solve the problem of wheelchair users crossing the stairs abroad is to use the emergency evacuation transport equipment of the building - the stair climber, which is to temporarily fix the wheelchair on the stair climber, so as to go up and down the stairs. Put it back to the origin...
