Abstract

The invention relates to a wheelchair capable of crossing obstacles and assisting in standing. The wheelchair capable of crossing obstacles and assisting in standing comprises a chair part, a switching mechanism and an auxiliary standing mechanism, wherein the switching mechanism is used for switching between roller wheel transmission and crawler wheel transmission of the wheelchair capable of crossing obstacles and assisting in standing; the crawler wheel transmission is provided with a first crawler wheel and a second crawler wheel which are connected through a bracket; and the auxiliary standing mechanism is used for assisting a user in standing. The wheelchair capable of crossing obstacles and assisting in standing adopts a double caterpillar track transmission mode when walking up and down the stairs and crossing obstacles. According to the wheelchair capable of crossing obstacles and assisting in standing, the switching mechanism adopts a five-rod mechanism to compensate the structural error of a four-rod mechanism, so that high-precision motion output is realized or a complicated motion rule is finished, switching between the roller wheel transmission and the crawler wheel transmission is realized, the auxiliary standing mechanism with a parallelogram structure can assist the user in standing, and obstacles can be crossed stably by the double caterpillar track transmission mode in the obstacle-crossing process.

Description

technical field [0001] The invention relates to the technical field of machinery and control, in particular to an obstacle-surmounting and standing-assisting wheelchair and a standing-assisting method thereof. 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 abroad to solve the problem of wheelchair users crossing the stairs is to use the emergency evacuation transport equipment of the building - the stair climber, which is about to temporarily fix the wheelchair on the stair climber, so as to go up and down the stairs. Put...
