Bionic lower-limb external bone robot for auxiliary handling

Abstract

The invention relates to a bionic lower limb external bone robot used for auxiliary handling, which consists of the left half part and right half part, the left and right half parts are with the samestructure, and the right half part of the invention includes: the waist module, hip module, thigh module, calf module and ankle joint module; the horizontal end surface far from the micro liquid motorof the L-type lumbar support of the waist module is fixed with a width adjustment plate, the width adjustment plate includes a hanger part and a flat part, the flat section is connected with the horizontal end of the L-type lumbar support. In the flat section, there is a limit groove in the horizontal direction, the width adjustment pressure block is installed in the limit groove, and the width adjustment is achieved by adjusting the sliding pressure of the pressure block in the limit groove. The ear piece is coupled with connecting piece of the lumbar support by shaft and sleeve, and the sleeve is positioned through the pin axis. The robot is easy to wear and the degree of freedom of outreach is increased in the hip joint, and it has biomimetic nature.

Description

technical field [0001] The invention relates to the technical field of power-assisted robots, in particular to a bionic lower-limb exoskeleton robot for auxiliary transportation. Background technique [0002] With the rapid development of the national economy, the manufacturing industry has become an important part of my country's economic development. In the production workshop, pure mechanical automation equipment has high environmental requirements and poor flexibility when handling materials, and most of them are mainly completed by manpower. However, due to the limited physical capacity of the human body when carrying it, the efficiency is relatively low. At the same time, long-term engagement in heavy load handling will cause chronic damage to the human body. Therefore, it is particularly important to invent a lower extremity exoskeleton assisting device that is light in size, strong in wearability, and assists people in efficient transportation. [0003] According ...

AI Technical Summary

Problems solved by technology

A motor plus a harmonic reducer is installed at the hip joint, and the movement of the exoskeleton is sensed and controlled through the encoder and controller, but the hip joint and knee joint only have flexion / extension degrees of freedom, and the ankle joint only has valgus / inversion The degree of freedom is retracted, the width of the waist cannot be adjusted with the human body, and the knee joint is not assisted
