Knee joint exoskeleton rehabilitation training wheelchair

Abstract

The invention provides a knee joint exoskeleton rehabilitation training wheelchair. The knee joint exoskeleton rehabilitation training wheelchair comprises a wheelchair body; knee joint exoskeleton structures are symmetrically arranged on two sides of the lower side of the wheelchair body; each knee joint exoskeleton structure comprises a double-knee width adjusting mechanism, a knee joint power mechanism, a knee joint inward / outward rotation and shank length adjusting mechanism, and an ankle joint and foot structure; the upper side of each double-knee width adjusting mechanism is connected with a wheelchair rigid cushion through a front sliding groove and a rear sliding groove; the front part of each double-knee width adjusting mechanism is hinged to the corresponding knee joint inward / outward rotation and shank length adjusting mechanism; the rear part of each double-knee width adjusting mechanism is hinged to the corresponding knee joint power mechanism; meanwhile the knee joint power mechanisms are connected with the knee joint inward / outward rotation and shank length adjusting mechanisms to form knee joint power flexion-extension structures; and the ankle joint and foot structures are connected with the knee joint inward / outward rotation and shank length adjusting mechanisms through a shank adjusting plate. Knee joint driving and executing mechanisms are connected with the wheelchair, and the exercise load of a patient in the middle rehabilitation stage is reduced.

Description

technical field [0001] The invention belongs to the technical field of rehabilitation robots, in particular to a knee joint exoskeleton rehabilitation training wheelchair. Background technique [0002] After knee replacement surgery, patients often use passive rehabilitation training devices to perform knee flexion and extension exercise training and lower limb muscle strength training to achieve the purpose of knee joint function recovery. The mode is relatively simple, and the recovery efficiency is relatively low. The dynamic knee rehabilitation training device is more powerful than the passive type, and can realize different training modes in different rehabilitation stages of the patient, increase the flexibility of the knee joint rehabilitation device and improve the patient's muscle control ability, but this kind of equipment compares Huge and expensive. [0003] The training methods of the rehabilitation device are generally lying posture and standing posture. The ...

AI Technical Summary

Problems solved by technology

[0005] In order to overcome the above technical problems, the object of the present invention is to provide a knee joint exoskeleton rehabilitation training wheelchair, which solves the problem that the human-computer interaction of the existing knee joint rehabilitation training device is not supple, poor in comfort, unable to resist impacts outside the plan, training, etc. When the patient's exercise load is too small or too large, it limits the movement of other degrees of freedom of the human knee joint except flexion and extension.
