Abstract

The invention discloses a crawler type wheelchair. The crawler type wheelchair comprises a body. A seat is installed on the body, a drive mechanism is installed on the inner side of the body, and crawler mechanisms are arranged on the two sides of the body and fixedly connected with the drive mechanism. Each crawler mechanism comprises a driving wheel, an installing frame, a first driven wheel set, a second driven wheel set, a third driven wheel set and a conveying belt. The driving wheels are fixedly connected with a drive shaft of the drive mechanism, the installing frames are fixedly connected with the driving wheels, and the first driven wheel sets are away from the ground and are fixedly connected to the installing frames transversely; the second driven wheel sets and the third driven wheel set are close to the ground and are fixedly connected with the installing frames, and the surfaces of the driving wheels, the surfaces of the first driven wheel sets, the surfaces of the second driven wheel sets and the surfaces of the third driven wheel sets are sleeved with the conveying belts. The crawler type wheelchair can achieve the stair climbing function.

Description

technical field [0001] The present invention relates to the field of vehicles for the disabled, more specifically to a crawler wheelchair Background technique [0002] Wheelchairs are an indispensable means of transportation for the elderly and infirm. But, traditional wheelchair just can't cross when encountering hurdle. Among them, going up and down stairs is the biggest obstacle for these people with disabilities. [0003] At present, the way abroad to solve the problem of wheelchair users crossing the stairs is to use the emergency evacuation transport equipment of the building - the stair climber, which is about to temporarily fix the wheelchair on the stair climber, so as to go up and down the stairs. Put it back to the original place after use, and the operation procedure is loaded down with trivial details. Although it can solve the problem of going up and down stairs for wheelchair users, it cannot go up and down stairs in buildings that are not equipped with sta...
