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 of crawler-type stair-climbing wheelchairs is high. Nurses need to undergo certain training to operate proficiently. In addition, when climbing up and down stairs, it is easy to cause damage to the edge of the stairs, thus damaging the appearance of the stairs
[0003] At present, the invention patent with the patent number 201210136341.2 solves the problem of automatic stair climbing, but there are still defects such as poor safety, poor stability, and inability to operate intelligently.

Abstract

The invention relates to the field of moving devices, and discloses a stair climbing method, a stair climbing wheel set and a stair climbing wheelchair with the wheel set; the stair climbing wheelchair comprises a connecting frame (4); one end of the connecting frame (4) is provided with a telescopic supporting rod (5), the other end of the connecting frame (4) is provided with climbing wheels; the climbing wheels comprise three inner wheels (2) and four outer wheels (3), wherein the connecting frame (4) is provided with inner wheel shafts (20) and outer wheel shafts (30), the outer wheel frame (31) is fixedly arranged on the outer wheel shaft (30) and drives the outer wheel shaft (30) to rotate; an inner wheel driving device (6) and an outer wheel driving device (7) are mounted on the connecting frame (4). The stair climbing mechanism is totally different from common stair climbing machines in the market. The mechanism is simple in structure, low in cost, intelligent in control, convenient to operate, reliable in braking, safe, stable and capable of effectively solving the problem that people having difficulty in moving walk walk up and down stairs.

Description

technical field [0001] The invention relates to the field of mobile devices, in particular to a method for climbing stairs, a wheel set for climbing stairs and a wheelchair for climbing stairs with the wheel set. 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 wh...
