Problems solved by technology

The former needs manual adjustment of the angle of the crawler when using it, and it does not realize the automation of climbing stairs. Although the latter can climb stairs automatically, the hydraulic system that provides power to adjust the angle of the track cannot accurately adjust the angle of the track, and the cost of the hydraulic system is very high. Oil in the event of a leak can make the wheelchair work environment worse

Abstract

A tracked wheeled transformable wheelchair comprises a wheelchair body and a wheel mechanism driving the wheelchair body to move. Two sides of the bottom of the wheelchair body are provided with a track mechanism, a lifting mechanism driving the track mechanism to ascend and descend, and a control system controlling the lifting mechanism to operate. The track mechanism comprises a main track and an auxiliary track. The rear end of the main track and the front end of the auxiliary track share a same track wheel which is hinged to the wheelchair body through a track support. The rear end of the auxiliary track tilts up to the rear of the wheelchair body. The front end of the main track is connected with the wheelchair body through the lifting mechanism. When the tracks are retracted, the wheelchair can travel as a common wheelchair; after the tracks can be manually lowered and tilted, the wheelchair can climb a staircase.

Description

technical field [0001] The invention relates to a wheelchair which is convenient for people with disabilities to go up and down stairs, in particular to a crawler and wheel type switchable wheelchair. Background technique [0002] Common crawler-type stair-climbing wheelchairs have two types: detachable crawlers and fixed and adjustable crawlers. The detachable track climbing wheelchair needs a special person to install the track on the ordinary wheelchair that matches the track when using it, and manpower is required to assist the wheelchair to climb stairs when working; the track climbing wheelchair can adjust the angle between the track and the wheelchair seat surface , so that the wheelchair can run normally like an ordinary wheelchair, and can also climb stairs when encountering stairs. Most of them use hydraulic jacks as the power to adjust the track, and a hydraulic power system needs to be set on the wheelchair. The former needs manual adjustment of the angle of the...
