Wearable type knee joint power-assisted robot

Abstract

The invention discloses a wearable type knee joint power-assisted robot. The wearable type knee joint power-assisted robot comprises a control system part (1), flexible execution mechanisms (2 and 3), foot sole thin film pressure sensor groups (4 and 5), and the like. The wearable type knee joint power-assisted robot has the advantage that a miniature air pump is used as a pneumatic power source, the flexible execution mechanisms (2 and 3) acting on knee joints adopt the air bag boosting and torsion spring energy accumulation combined type flexible action method, the gait parameters are collected and fed back in real time by the foot sole thin film pressure sensor groups (4 and 5), the flexible execution mechanisms (2 and 3) are controlled in real time by the control system part (1) of the knee joint power-assisted robot, and the flexible torque which assists the bending and extension of the knee joints is provided according to the gait cycle in the people walking process, so that the purpose of flexible walking assisting is realized for persons with degraded lower limb exercise capacity or without lower limb exercise capacity.

Description

technical field [0001] The invention belongs to the field of flexible exoskeleton robot technology and wearable power-assisted robots, in particular to a wearable knee-joint power-assisted robot. Background technique [0002] With the degeneration of muscle strength and cardiopulmonary function in the elderly, the proportion of walking in daily activities gradually decreases, which leads to a sharp increase in the incidence of various diseases. Such a vicious circle eventually leads to the complete loss of exercise capacity. In addition, mild stroke patients will also cause partial disability of lower limb motor ability, affecting the patient's mobility. For the special requirements of the elderly with reduced lower limb movement ability or the partially disabled people with lower limb movement, the wearable knee robot can be easily worn on them. When people walk, the robot can provide assistance to people, so as to reduce the decline in lower limb movement ability The stre...

Problems solved by technology

[0003] At present, the development of most wearable knee-joint robot equipment focuses on the realization of functions, but there are great shortcomings in the design of wearing convenience, which cannot be put on and taken off freely and quickly, and the wearing comfort is not good.

In addition, this type of robot has many parts and its own weight is rel...
