A multifunctional wheelchair

Abstract

The invention relates to a multifunctional wheelchair, and the wheelchair comprises a wheelchair main body (10), a folding chair back (20), a lifting device (30), a pedal supporting device (40), and a downhill buffering device (50), wherein the folding chair back (20) is located at the back of a chair back (101). A side surface of the bottom of a tube body (301) of the lifting device (30) is connected with an inflation pipe (304). The bottom of a supporting rod (401) of the pedal supporting device (40) is connected with one end of a lever (403), and a rotating shaft of a motor (501) of the downhill buffering device (50) is provided with a driving gear (502) which is connected with a connecting shaft (104) of the wheelchair main body (10). According to the invention, the back of the wheelchair can be folded for the leaning of the head of a person. The wheelchair can be lifted through the lifting device (30) according to the needs, and four supporting legs of the pedal supporting device (40) can independently support pedals, thereby bringing convenience to a patient for standing on the ground stably. The downhill buffering device (50) can enable the wheelchair to be limited by a motor braking force during downhill, and can support and fix legs.

Description

[0001] Technical field: [0002] The invention relates to the field of medical equipment, and more specifically relates to a multifunctional wheelchair. [0003] Background technique: [0004] The wheelchair is an important tool for rehabilitation. It is not only a means of transportation for the physically disabled, but more importantly, it enables them to perform physical exercises and participate in social activities with the help of a wheelchair. It is also an indispensable tool for moving patients in a medical environment. Ordinary wheelchairs are generally composed of four parts: wheelchair frame, wheels, brake device and seat. On the basis of ordinary wheelchairs, hand-operated wheelchairs are equipped with hand-operated devices. The backs of ordinary wheelchairs are of ordinary height. When some seriously ill patients need to lean their heads when sitting in wheelchairs, ordinary wheelchairs cannot. It is inconvenient to carry the patient; when some patients stand up ...

AI Technical Summary

Problems solved by technology

The backs of ordinary wheelchairs are of ordinary height. When some seriously ill patients need to lean their heads when sitting in wheelchairs, ordinary wheelchairs cannot. It is inconvenient to carry the patient; when some patients stand up from the wheelchair, they stand on the pedals at the front of the wheelchair with both feet or one foot, because there is no support at the bottom of the pedals, it may cause the patient to fall; push the wheelchair down When going uphill, the wheelchair will accelerate downhill, which may cause the patient to fall due to too fast speed; for some patients with lower limb injuries or leg fractures, the lower limbs need to be supported and fixed, which cannot be done by ordinary wheelchairs. The seat height can be adjusted, the pedals can be supported independently, the downhill has a buffer function, and the legs can support a fixed wheelchair device, so these problems can be solved, so it is very beneficial to design a multifunctional wheelchair
