Abstract

The invention discloses an upper limb exoskeleton based on a parallel driving joint, relates to an assist robot, and aims to solve the problems of poor motion accuracy, large size and small motion range of an upper limb exoskeleton robot. The upper limb exoskeleton comprises a shoulder joint, an elbow joint and a wrist joint, wherein the shoulder joint, the elbow joint and the wrist joint are arranged in sequence; an elbow connecting plate on the elbow joint and a shoulder fixing frame on the shoulder joint are arranged one above the other; a wrist connecting plate on the wrist joint and an elbow fixing frame on the elbow joint are arranged one above the other; a second long connecting slot in the elbow connecting plate is in sliding connection with a first long connecting slot in the shoulder fixing frame; a fourth long connecting slot in the elbow connecting plate is in sliding connection with a third connecting long slot in the elbow fixing frame. The upper limb exoskeleton is applied to assistance of the aged and disabled, medical rehabilitation and the like.

Description

technical field [0001] The invention relates to an assisting robot, in particular to an upper limb exoskeleton based on parallel drive joints. Background technique [0002] At present, the exoskeleton robot can bear the load for the human body and increase the mobility of the human body. It has great application prospects in various aspects, such as military marching, earthquake rescue, and human muscle rehabilitation. However, the existing upper extremity exoskeletons Skeletal design is mostly based on serial structure design, which has poor motion accuracy, and each degree of freedom is driven by a separate motor, which makes the motor burden heavy, resulting in an increase in the size of the motor. However, the existing parallel structures are mostly in the form of connecting rod hinges, and the range of motion is also greatly limited. Contents of the invention [0003] The present invention proposes an upper limb exoskeleton based on parallel drive joints in order to ...
