Lightweight bionic upper-limb exoskeleton rehabilitation robot system

Abstract

The invention discloses a lightweight bionic upper-limb exoskeleton rehabilitation robot system. The system is a device for robot-assisted rehabilitation training. The system comprises a shoulder joint exoskeleton module, an elbow joint exoskeleton module, a wrist joint exoskeleton module and a hand handle module, and all the modules are connected through screws to form the whole system. The robotsystem totally has seven degrees of freedom, wherein the shoulder joints include three degrees of freedom, the elbow joints include two degrees of freedom, and the wrist joints include two degrees offreedom. The shoulder joint module is connected with a back size adjusting module; the elbow joint module is connected with the shoulder joint module and the wrist joint module separately; the wristjoint module is connected with the hand handle module. According to the system, all the joints are driven by a small-sized motor and a speed reducer to move separately, and through the adjustable design, it is guaranteed that the exoskeleton is kept coaxial to the degree of freedom of the human body; through bionic design, the comfort of the system is improved; through the wearable design of the exoskeleton, the problem that the using position of traditional rehabilitation equipment is limited is solved, and the system has the advantage of being light.

Description

technical field [0001] The invention relates to a medical rehabilitation training system, in particular to a light-weight bionic upper limb exoskeleton rehabilitation robot. Background technique [0002] Modern society is an era of high-speed operation, technology is changing with each passing day, people's life rhythm is rapidly accelerating, and life pressure is gradually increasing. In such an environment, loss of mobility or impairment of motor ability will bring a lot of inconvenience to people's life, which greatly affects the quality of life. Therefore, how to help patients regain mobility and live independently and freely has become a research hotspot in the fields of rehabilitation medicine and engineering. At present, traditional medical rehabilitation training is mainly performed by professional rehabilitation therapists with bare hands. Such methods are time-consuming, laborious and tedious for patients themselves, their families and medical staff. Moreover, du...

AI Technical Summary

Problems solved by technology

However, the existing exoskeleton-type upper limb rehabilitation robots have relatively single product functions in the field of rehabilitation, and their application is limited to some joints. Very few integrated products can realize the rehabilitation training of each joint of the upper limbs, and the main structure design of some models is not ideal. , it is impossible to truly simulate the movement of the upper limbs, so it is difficult to meet the requirements of lightness, flexibility and comfort for rehabilitation training of affected limbs
