Abstract

The invention relates to an electric stair climbing wheelchair. The electric stair climbing wheelchair comprises a frame, armrests, a driving wheel, a driving motor, a steering wheel and a steering wheel controller. A stair climbing driving mechanism comprises a tooth ring, a telescopic tooth electric push rod, telescopic teeth, a hub connecting flange, an eccentric circle, a limiting plate and a shaft sleeve. The tooth ring is installed on the inner side of a hub of the driving wheel through a connecting angle. Telescopic holes are machined in the tooth ring and evenly distributed in the tooth ring, and the telescopic teeth are installed in the telescopic holes of the tooth ring. The eccentric circle is installed on a motor shaft of the driving motor and limited by the limiting plate and the shaft sleeve. A telescopic auxiliary wheel mechanism comprises an auxiliary wheel carrier, a shear type telescopic frame, an electric push rod, a lower guide rod, an auxiliary wheel, an upper guide rod and an auxiliary wheel. The driving wheel can better exert climbing driving force through the telescopic teeth to drive the stair climbing wheelchair to finish stair climbing operation, the electric wheelchair has the upstairs going, downstairs going and normal ride-instead-of-walk driving functions, the problem that old people or people unable to move freely drive the wheelchair and go upstairs and downstairs alone is solved, and the use performance and safety of the electric stair climbing wheelchair are improved.

Description

technical field [0001] The patent of the invention belongs to the technical field of machinery and electric vehicles, and relates to an electric wheelchair for climbing stairs. Background technique [0002] Wheelchairs are means of transportation for people with disabilities and walking difficulties. Among the currently used wheelchairs, there are human-driven and electric-driven types, and these forms of wheelchairs are relatively mature technologies for driving on flat or less sloped ground. 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 wheelchairs, but there are some defects. The five-star wheel type stair-climbing wheelchair needs manpower to push and pull when going up and down the stairs, so 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 staf...
