Lower limb rehabilitation training wheel

Abstract

The invention relates to a lower limb rehabilitation wheel which is a device for fixing moving tracks in a movable plane through tandem connection of connecting rod mechanisms. The device is driven by a power mechanism, is fixedly arranged below a wheel chair, and can be used for low limb rehabilitation and training activities of the disabled and the old. The lower limb rehabilitation training wheel is composed of a crank rocker mechanism, a parallelogram mechanism, a pedal plate rotating mechanism and a stepping motor (1) fixed on a fixing piece. The crank rocker mechanism is composed of a first crank, a first connecting rod, a second crank and a rocker. The parallelogram mechanism is composed of a second connecting rod, a third connecting rod, a fourth connecting rod, a fifth connecting rod, and a sixth connecting rod. The pedal plate rotating mechanism is composed of a pedal plate rotating piece and a pedal plate. Through simple tandem connection structures such as cranks and rockers, the lower limb rehabilitation wheel can help a patient to conduct rehabilitation training and complete lower limb exercise functions, and quickens the rehabilitation progress. The device is simple in structure and practical, has the advantages of stable exercise and high rigidity, and is low in cost. The realization of the functions mainly depends on driven by a motor. The lower limb rehabilitation wheel has high utilization performance and popularization value.

Description

Technical field [0001] The invention involves the field of rehabilitation equipment technology. Specifically, it is a kind of lower limb rehabilitation training wheelchair.Through the connecting mechanism, a device that can achieve a fixed motion trajectory can be achieved in the XOY plane. This device is driven by the power mechanism and is fixed below the wheelchair. It can be used for the rehabilitation and training activities of the disabled and the elderly. Background technique [0002] The rehabilitation training of some diseases is important to the recovery of physical function.At present, there are many types of lower limb rehabilitation training instruments. According to the degree of complexity, there is a separate sports institution, which is integrated with bed design;Standing.However, the use of leg rehabilitation training institutions for wheelchair sitting position is rarely used.There are few research on the combination of the rehabilitation trainers of the links ...

AI Technical Summary

Problems solved by technology

Existing rehabilitation devices for lower limbs can only achieve standing and sleeping positions, and have a complex structure. They can only perform rehabilitation training in a fixed indoor position, and cannot perform rehabilitation training outdoors or in a sitting position, and even bring additional pain to patients participating in rehabilitation training. hurt and pain
