Problems solved by technology

[0003] At present, the common electric wheelchairs mainly include all-wheel type, star wheel type, crawler type and stepping support type. Among them, the all-wheel type wheelchair needs a special person to move the wheelchair when climbing stairs, which is very heavy and inconvenient and brings great inconvenience to the occupants. Uncomfortable; crawler wheelchairs have a complex structure, and there are bumps when going up and down stairs, and it is inconvenient to use on flat

Abstract

The invention discloses a wheelchair with a stair climbing function. The wheelchair comprises a seat mechanism, seat lifting mechanisms, a crawler driving mechanism and a flat land driving mechanism,wherein the seat lifting mechanisms are symmetrically arranged on seat frameworks on two sides of a seat plate, the tops of seat lifting rods are connected with the seat plate, and seat hydraulic cylinders are fixedly installed on the seat frameworks; the crawler driving mechanism comprises crawlers, a walking mechanism platform and crawler lifting mechanisms, the bottoms of crawler lifting rods of the crawler lifting mechanisms are connected with the walking mechanism platform, and the crawler hydraulic cylinders are fixed at the bottoms of the seat frameworks; the flat land driving mechanismcomprises a pair of rear wheels and a pair of front wheels, the front wheels are fixed below the seat frameworks through front wheel shafts and front wheel supporting frames, and the rear wheels aredriven through a rear driven motor. According to the wheelchair, the transition between the stair climbing process and the flat land driving process is completed through a hydraulic mechanism, so thatthe switching of stair climbing and flat land driving of the wheelchair is smoother and more convenient, and the wheelchair has the advantages of being simple in structure and convenient to use.

Description

technical field [0001] The invention relates to the technical field of electric wheelchairs, in particular to an electric wheelchair with the function of climbing stairs. Background technique [0002] In today's society, China has already entered an aging society. The number of elderly people living in China has reached 132 million. The average annual growth rate of the elderly population is 3.30%, and it continues to grow. In addition, there are about 60 million people with various disabilities. The increasing number of the elderly and the disabled makes it not only a practical need to help the disabled to carry out their daily lives independently, but also a social issue of caring for the mental health of the elderly and the disabled. [0003] At present, the common electric wheelchairs mainly include all-wheel type, star wheel type, crawler type and stepping support type. Among them, the all-wheel type wheelchair needs a special person to move the wheelchair when climbing...
