Auxiliary power upper limb exoskeleton

Abstract

The invention belongs to the technical field of upper limb exoskeletons and particularly relates to an auxiliary power upper limb exoskeleton, comprising: a back connection module that allows carrying on the back through a strap; two big arm extension modules arranged on the left and right of the back connection module respectively and movably connected with the back connection module; two big arm back-forth motion modules movably connected to the big arm extension modules; two elbow rotation modules movably connected to the big arm back-forth motion modules; two forearm rotation modules movably connected to the elbow rotation modules and which limit forearm rotation angle ranges of the forearm rotation modules by using incomplete gear structure; two wrist motion modules movably connected to the forearm rotation modules. The auxiliary power upper limb exoskeleton disclosed herein can assist a patient in living by driving his or her big arms, forearms and palms, is applicable to upper limb rehabilitation training for patients, and is novel in structure and comfortable to wear.

Description

technical field [0001] The invention relates to an auxiliary power upper limb exoskeleton. The invention belongs to the technical field of upper limb exoskeleton robot equipment. 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 assistanc...

AI Technical Summary

Problems solved by technology

[0004] 1. The mechanism is complex and bloated, and it is inconvenient to wear. The desktop mechanism is used to integrate the power supply and drive equipment inside the platform, which makes the mechanical mechanism huge and inflexible. It has high requirements for the use of space and is not easy to carry and popularize.

The joints of its arm mechanism adopt the design of motor superimposed reducer, which is very bulky, which makes it inconvenient for users to wear and feels heavy

[0005] 2. The traditional upper limbs are made of all-metal materials, and the reducer adopts multi-stage steel reducer, which has the defects of heavy weight and high noise. In addition, the protruding motor and reducer are easy to interfere with the external environment, resulting in unpredictable risks of

[0006] 3. Because the traditional upper limb rehabilitation is designed as an integrated structure, it is relatively rigid and cannot be carried by the user to meet their different training needs, and cannot assist patients in their daily life
