Abstract

The invention relates to a stair-climbing wheelchair which comprises a seat, power wheels and a supporting frame, wherein the seat is arranged above the supporting frame and supported by the supporting frame, and the power wheels are respectively arranged at the rear parts of the two sides of the seat; meanwhile, the stair-climbing wheelchair also comprises rocking levers respectively arranged the two sides of the seat, a chain wheel drive device, a crawler-type bearing wheels, a worm wheel and a worm, wherein the worm is meshed with the worm wheel; the base end of the worm is connected with the chain wheel drive device arranged on the supporting frame; the worm wheel is connected with the power wheels by virtue of the worm so as to adjust the steering angles of the power wheels; one end of the crawler-type bearing wheel is fixedly connected with the chain wheel drive device, the crawler-type bearing wheel is connected with the front end of the supporting frame and the power wheels byvirtue of a crawler, and belt wheels are respectively arranged at the joint of the crawler and the supporting frame and the joints of the crawler and the power wheels. By using the stair-climbing wheelchair provided by the invention, the problem that people suffering lower limb disabilities or incapable of walking normally duo to injuries are difficult to carry out daily travel and walk up and down the stairs can be solved; the stair-climbing wheelchair is simple and reasonable in structure and low in cost; and because of being driven by human power, the wheelchair is energy-saving and environmentally-friendly.

Description

Technical field [0001] The invention relates to a wheelchair for climbing stairs suitable for people with lower limbs disabled or unable to walk normally due to injuries. Background technique [0002] With the development of the city, more and more stairs are used in daily life. For wheelchair users, various stairs have become obstacles to their activities. At present, there are many design inventions for stair-climbing wheelchairs on the market, which mainly change the traditional structure to realize the wheelchair's going up and down, or design the wheelchair as a stair-climbing robot to realize the wheelchair's going up and down. However, the products manufactured by the prior art have complex structures, high costs, and high prices, which are not easily accepted by ordinary wheelchair users. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide a stair climbing wheelchair with simple and reasonable structure, low cost, an...
