Abstract

The invention discloses a variable wheel type stair climbing wheelchair which comprises a frame, a seat and a wheel train mechanism. The seat is arranged on the frame, the wheel train mechanism comprises front wheels and a variable-form rear wheel system, the front wheels are planet wheels and arranged on two sides of the front end of the frame respectively, the variable-form rear wheel system is arranged on two sides of the rear end of the frame, comprises variable-form rear wheels arranged on a drive shaft and include a driving wheel and a driven wheel, the driving wheel can be relatively and rotatably connected with the driven wheel, both the driving wheel and the driven wheel comprise a hub and three equally distributed arcs, and the three arcs are arranged on the outer surfaces of the hub in a surrounding manner. By the aid of the variable wheel type stair climbing wheelchair, the variable-form rear wheels are mutually matched with the planet type front wheels, stability and safety of the wheelchair are improved, and the wheelchair is simply and conveniently operated by a user.

Description

technical field [0001] The invention relates to the field of mechanical equipment, in particular to a stair climbing wheelchair with variable wheels. Background technique [0002] There are a large number of old, weak, sick, and disabled groups in the country. It is inconvenient for outdoor and indoor climbing stairs, and the demand for means of transportation is increasing. In order to solve the practical problems of these special groups, various forms of variable wheel stair-climbing wheelchairs have been adopted at home and abroad, including manual and electric stair-climbing wheelchairs, including crawler type, wheel group type, track type, etc. The Chinese patent publication number is CN101703440A, and the name is an electric stair-climbing wheelchair, which is a kind of crawler-type stair-climbing wheelchair, which uses the crawler to move smoothly and adapt to a wide range of terrain; The wheelchair is a wheeled stair-climbing wheelchair. The front wheel adopts a pla...
