Wheelchair and operation method thereof

Abstract

The invention provides a wheelchair and an operation method thereof. According to the technical scheme, hand wheel rings of a traditional wheelchair are removed, and ratchet wheel drive rods capable of resetting automatically are mounted on hubs of vehicle wheels. The ratchet wheel end of each ratchet wheel drive rod is fixed on the hub of the vehicle wheel, and the other end of the ratchet wheel drive rod is a free end, which can carry out reciprocated circular motion around the axle, and act to drive the wheelchair to move. The ratchet wheel drive rods are provided with elastic pieces for connection with a frame, and after acting, under drive of the elasticity of the elastic pieces, the ratchet wheel drive rods automatically reset to the initial position. Due to change of the force application mode and direction, a user can drive with arm force or elbow force, which is far powerful than the wrist force; meanwhile, due to the lever principle of the ratchet wheel drive rods capable of resetting automatically, the patient can relatively conveniently operate the wheelchair and can save abundant force, the patient with the handicapped lower limbs can move for a long distance conveniently, and thus the patient with the handicapped lower limbs is enabled to go out conveniently.

Description

Technical field: [0001] The invention relates to the field of medical equipment, in particular to a wheelchair and an operating method thereof. Background technique: [0002] Wheelchair is an important tool for rehabilitation. It is not only a means of transportation for physically disabled and handicapped people, but more importantly, it enables them to perform physical exercises and participate in social activities with the help of wheelchairs. Ordinary wheelchairs are generally composed of four parts: wheelchair frame, wheels, brake device and seat. [0003] The hand wheel is unique to wheelchairs, and its diameter is usually 5cm smaller than that of the large wheel. It is generally pushed directly by the patient with the wrist. For easy driving, the following changes can be made: (1) Add rubber to the surface of the hand wheel rim to increase friction. ⑵ Add push handles along the circumference of the hand wheel. However, due to the position and size factors of the se...

AI Technical Summary

Problems solved by technology

However, due to the position and size factors of the seat, arm length, and rim, it is not conducive to the occupant to apply force, and the conversion effect of the wrist force is also very poor. , easier to operate? Power conversion works better? What about wheelchairs that are convenient for people with lower limb disabilities to walk long distances and can make travel more convenient for people with lower limb disabilities?
