Abstract

The invention discloses a crawler-type stair-climbing wheelchair with a seat balance device, which includes a crawler chassis, a seat body, a seat cylinder, a support frame, a position switch, and a wheelchair frame in a frame-type mechanism. The seat body is rotatably connected with the wheelchair frame, the front end of the piston rod of the seat cylinder is fixed on the bottom surface of the seat body on one side of the rotating shaft, the position switch includes contacts and a position switch body, the front end of the crawler chassis and The rear ends are all equipped with contacts, and the positions of the contacts are respectively provided with corresponding position switch bodies when the crawler chassis is in the inclination angle of the state of climbing stairs and the state of descending stairs, and the position switches respectively control Advance and return of the seat cylinder. The present invention triggers the position switch through the contact between the front end or the rear end of the crawler chassis and the wheelchair frame, so that the seat cylinder under the seat body makes a corresponding action, thereby keeping the seat in a stable state, which is conducive to improving the safety of users .

Description

technical field [0001] The invention relates to the technical field of wheelchair manufacturing, in particular to a crawler-type stair-climbing wheelchair with a seat balancing device. Background technique [0002] With the intensification of the aging population in China: by the end of last year, the population over 60 years old in mainland China had reached 220 million, accounting for about 16.1% of the total population. In addition, the number of people with disabilities has reached 40 million. How to help the above-mentioned groups to better integrate into society and live and work in peace and contentment is a major problem that needs to be solved urgently in Chinese society. [0003] Wheelchairs have been used as a means of transportation for special groups of people for a long time, but ordinary wheelchairs cannot be used in complex road conditions such as stairs and ravines, and stair-climbing wheelchairs are needed to help them solve this dilemma. However, in the p...
