Abstract

The invention discloses a flexible transmission upper-limb exoskeleton robot for wearing, relates to a robot for wearing, and aims to solve such problems as low rigidity and weak loading capacity due to an upper-limb exoskeleton robot belonging to a serial connecting structure and caused incapability of safe and reliable life assistance for weak people. A wrist joint mechanism comprises a wrist joint driving fixed wheel, a human body palm fixed piece, a wrist joint moving wheel connecting piece, a wrist joint planet gear, a wrist joint driving rod, a wrist joint driving rod power input wheel, an exoskeleton front arm, an L-shaped connecting piece and a wrist joint steel wire rope; an elbow joint mechanism comprises an elbow joint planet gear, an elbow joint planet gear support frame, a first elbow joint driving fixed wheel, a second elbow joint driving fixed wheel, an elbow joint connecting upper arm frame, a U-shaped frame body and an elbow joint steel wire rope; and a shoulder joint mechanism comprises a shoulder joint planet gear, a shoulder joint driving fixed wheel, an exoskeleton support piece, a jack component, a shoulder joint driving fixed wheel connecting plate, a shoulder joint driving piece, an exoskeleton upper arm, a shoulder joint steel wire rope and an exoskeleton upper arm connecting shaft. The flexible transmission upper-limb exoskeleton robot for wearing is applied to the field of robot operation.

Description

technical field [0001] The invention relates to a wearable robot, in particular to a wearable flexible upper limb exoskeleton robot. Background technique [0002] At present, many countries are facing the problem of population aging, such as China, Japan, and Italy. With the acceleration of the pace of life today, the probability of various motor dysfunctions in the elderly is also increasing year by year. At the same time, people with impaired or disabled physical functions also face the problem of motor dysfunction. Upper limb motor function assistance and upper limb motor function rehabilitation training play a vital role in frail people. The upper extremity exoskeleton can better assist the infirm. At present, the upper extremity exoskeleton robot belongs to the series structure, which has problems such as low rigidity and poor load-bearing capacity. As a result, it cannot be used safely and reliably for the life assistance of the infirm. Therefore, a kind of Robots t...
