Problems solved by technology

The five-star wheel-type and crawler-type stair-climbing wheelchairs in the prior art can basically solve the problem that people in wheelchairs go up and down stairs together with the wheelchair, but there are some defects: the five-star-wheel type stair-climbing wheelchair needs manpower to push and pull when going up and down stairs, Therefore, the stability is poor and the safety factor is low; when the crawler-type stair-climbing wheelchair goes up and down the stairs, the nursing staff needs to push the wheelchair to the stairway, and then operate the stepping motor to control the movement of the crawler belt
Crawler-type stair climbing wheelchairs are bulky and heavy, and the manufacturing cost is high. Nursing staff need to undergo certain training to operate proficiently

Abstract

The invention discloses an electric stair climbing wheelchair, which comprises a chair body, planetary wheel groups, a driving mechanism and chair surface adjusting mechanisms, wherein a planetary wheel group is arranged on left and right sides below a chair surface respectively, and is connected integrally through a transmission shaft; a wheel disc frame of each planetary wheel group is a regular geometric plate or a radioactive column; a planetary wheel is arranged at a distal end; the chair surface adjusting mechanisms are arranged one after the other below the chair surface; the main body of each chair surface adjusting mechanism has an oblong-shaped frame structure; the back end of each chair surface adjusting mechanism is hinged on the back part of a chair frame; and the middle front part of each chair surface adjusting mechanism is hinged with the chair frame through a push-pull rod. The electric stair climbing wheelchair disclosed by the invention has a relatively simple structure, is convenient to operate, runs stably, and is safe and reliable.

Description

technical field [0001] The invention relates to a riding vehicle capable of climbing stairs, in particular to an electric wheelchair for climbing stairs. Background technique [0002] There are a large number of disabled and elderly people who need to go out in wheelchairs due to physical defects or diseases. When they live in buildings without elevator facilities, going up and down stairs becomes difficult. The five-star wheel-type and crawler-type stair-climbing wheelchairs in the prior art can basically solve the problem that people in wheelchairs go up and down stairs together with the wheelchair, but there are some defects: the five-star-wheel type stair-climbing wheelchair needs manpower to push and pull when going up and down stairs, Therefore, the stability is poor and the safety factor is low; when the crawler-type stair-climbing wheelchair goes up and down the stairs, the nursing staff needs to push the wheelchair to the stairway, and then operate the stepping mo...
