Wearable shoulder assisting exoskeleton

Abstract

The wearable shoulder power-assisted exoskeleton comprises a wearable assembly, a power-assisted assembly and an arm supporting assembly, the wearable assembly comprises a waistband provided with a waist fixing plate, the power-assisted assembly comprises a tension spring, a pull rope and a supporting rod, one end of the supporting rod is movably connected and fixed to a base on the waist fixing plate, and the other end of the supporting rod is movably connected and fixed to the waist fixing plate. One end of the tension spring is connected to a support on the supporting rod through a first adjuster, the other end, away from the support, of the tension spring is connected to the adjusting block through a pull rope, and the adjusting block slides in a first sliding groove in the switching block through adjustment of a second adjuster arranged at one end of the switching block. And the adapter block transmits the assisting power generated by the assisting power assembly to the arm supporting assembly connected with the other end of the adapter block. The tension spring is used as an energy storage element to provide constant upward supporting force for the arm of the human body, no power source is needed, and flexibility, comfort and practicability of the exoskeleton can be achieved by adopting a bionic simple mechanical structure.

Description

technical field [0001] The invention relates to the technical field of exoskeletons, in particular to a wearable shoulder assist 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 a...

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
