Portable folding wheelchair

Abstract

Provided is a wheelchair assisting people disabled in lower limbs in moving. Members of the wheelchair such as a seat and a backrest are unfolded or folded through variable geometric structures connected with each other so as to achieve the goal of minimizing an occupied space when the wheelchair is carried. Besides, a manual driving device and an electric driving device can be added to frames of the structures so as to facilitate long-distance walking of the people disabled in the lower limbs. The people disabled in the lower limbs can go out or ride in various vehicles conveniently.

Description

technical field [0001] The invention relates to a wheelchair for assisting mobility of persons with disabilities with lower limbs. The wheelchair can be folded and has a small size, so that people with lower limb disabilities can travel or carry various means of transportation more conveniently. Background technique [0002] Folding wheelchairs that are generally popular in daily life can be reduced in size by folding, but when carrying various vehicles, the storage and placement are still limited by the space of the vehicle. In particular, relying on the arm to paddle the attached wheel as the driving method cannot apply continuous and uninterrupted power to the wheel, so it is not convenient for long-distance walking; the activity space of the handicapped is greatly limited. Because the diameter of the wheel that the arm strokes is relatively large, it is also the biggest obstacle to reducing the volume of the wheelchair. [0003] Although electric wheelchairs reduce the...
