Passive arm assisting exoskeleton

Abstract

The passive arm assisting exoskeleton comprises a wearing assembly, a supporting rod and an arm assisting assembly, a positioning device rotationally connected with the supporting rod is arranged at the bottom of the supporting rod, the positioning device is detachably installed on the wearing assembly, and the top of the supporting rod is hinged to the arm assisting assembly; the arm assisting assembly comprises an assisting generator, an assisting adjuster and a telescopic sleeve hinged to the top of the supporting rod, the assisting adjuster comprises an adjusting block, a grooved wheel and an adjusting knob, the assisting generator comprises a steel wire rope and an elastic element, and the head of the steel wire rope is fixedly connected with a pressing block at the end of the elastic element; the end of the steel wire rope penetrates through the grooved wheel to be fixedly connected with the supporting rod, and the arm assisting assembly transmits assisting force to the arm of a user through the arm hoop sleeve. An external power source is not needed, constant upward supporting force is directly provided for the arms of the human body, the structure is simple, the human engineering is met, dismounting and mounting are convenient, meanwhile, the assisting force can be changed through the assisting force adjuster, and flexibility, comfort and practicability of the exoskeleton are achieved.

Description

technical field [0001] The invention relates to the technical field of exoskeletons, in particular to a passive arm-assisted exoskeleton. Background technique [0002] With the development of society, the society is gradually entering an aging society. In some industries such as construction and decoration, the degree of automation is not high, requiring a lot of manual labor to participate in the scene, or in the scene where the lifting posture needs to be maintained for a long time. The proportion of older workers is still relatively high. Due to their older age and limited physical strength, these workers are prone to physical overdraft and other phenomena due to their older age and limited physical strength. They are prone to physical overdrafts and other phenomena. After working for a long time, their health is affected, and work efficiency is reduced in mild cases, and life safety is threatened in serious cases. [0003] A mechanical exoskeleton is a device that assis...

Problems solved by technology

According to the classification of power sources, it can be divided into powered exoskeletons and passive exoskeletons. Powered exoskeletons can achieve greater power assistance through the design of motors or cylinders, but they are large in size and poor in comfort, and are not suitable for the above scenarios; passive exoskeletons The exoskeleton uses energy storage components such as springs, elastic bands and other components to achieve power assistance

Due to the structure of the human body, it is laborious to lift the arm no matter where the arm is. When the arm is lifted, especially when there are tools or heavy objects on the arm, the shoulder muscles are prone to fatigue after a long time, and the existing The exoskeleton does not have quick disassembly and maintenance, which brings some inconvenience to the actual operation process
