A kind of shoulder-assisted lifting exoskeleton

Abstract

The invention discloses a shoulder assistance support exoskeleton. The shoulder assistance support exoskeleton comprises an assistance module, a force transfer module and a main body connecting module; the main body connecting module comprises a waist belt worn on the waist and being adjustable in size; size-adjustable shoulder belts are fixedly connected with the waist belt; the back part of thewaist belt is vertically and fixedly connected with a lower adjusting plate; a lower connecting plate is fixedly connected with an adjustable main connecting plate; the main body connecting module mainly bears total support force; the positions of a first connecting rod and a second connecting rod in the force transfer module can be changed, so that the support force can be transferred, the shoulder moving range is widened, and the shoulder motion flexibility demands are met; the assistance module comprises a main shell, a cam spring energy storage module arranged in the main shell as assistance, and upper arm binding tools fixedly connected to a main shell base; the upper arm binding tools are fixed on the upper arms of users; the assistance module can realize assistance of the human shoulders in a self-adaption mode; the free swing of arms in a non-working section under a chest is not influenced; and the shoulder assistance support exoskeleton has the characteristics of high flexibility, no resistance, portability and easy wearing.

Description

technical field [0001] The invention belongs to the technical field of robots, in particular to a shoulder-assisted lifting exoskeleton. Background technique [0002] In working scenarios such as factories and warehouses, workers need to lift heavy objects for a long time. Repetitive upper limb work can easily lead to upper limb musculoskeletal disorders; manual lifting of heavy objects and prolonged standing can easily lead to low back pain and varicose veins. The shoulder exoskeleton can provide shoulder support. When workers lift heavy objects, it can effectively reduce the stress on the shoulders and enable users to work for a long time, reducing the injury of workers' shoulder muscles. [0003] Existing upper extremity exoskeletons are mostly powered by motors, hydraulic pressure, etc., and are mainly used in the field of rehabilitation. Existing powered upper extremity exoskeletons mainly add motors to joints such as shoulders to assist the arms. However, under the ...

AI Technical Summary

Problems solved by technology

[0005] 1. Existing upper extremity exoskeletons are mostly driven by power. Powered upper extremity exoskeletons are bulky and have short battery life, which is not conducive to the wearing and use of workers in the industrial field.

[0006] 2. The degree of freedom of the exoskeleton is single, and the range of motion is relatively limited, mainly at the shoulder joint, which cannot meet the needs of flexible movement of the human body

[0007] 3. In non-working mode, or when the wearer's arm swings down, the exoskeleton creates resistance to the arm, interfering with the wearer's normal activities
