Upper limb carrying power assisting device based on pneumatic muscles

Abstract

The invention discloses an upper limb carrying power assisting device based on pneumatic muscles. The upper limb carrying power assisting device comprises main body mechanical structure design, driver selection and control methods. In the lifting and carrying process of a wearer, for waist joint rotation, loads are transmitted to the legs through structural design, and assistance is achieved through thigh counterforce; for the shoulder joints, ratchet wheel and pawl mechanisms are designed to realize supporting assistance; and as for the elbow joints, assistance is achieved through the pneumatic muscles and line driving. The whole mechanism adopts multi-degree-of-freedom adjustable design and accords with ergonomics; the pneumatic muscles are used as a driver, so that the light weight of the device is realized; and a voice module is used for recognizing the motion intention of the wearer, and then the power assisting device is controlled to operate. Aiming at the working conditions of industrial production, warehouse carrying and the like, a good assisting effect on the waist, shoulder and elbow joints of a user can be achieved.

Description

technical field [0001] The invention belongs to the field of assisting devices, in particular to an upper limb carrying assisting device based on pneumatic muscles. Background technique [0002] Since the industrial age, the idea of ​​developing a device that can combine human intelligence and machine kinetic energy to expand human physical capabilities has been a major engineering research direction. In recent years, with the development of mechanical and electronic engineering, more and more exoskeleton devices have begun to be put into practical tests and applications. [0003] In the future, with the rapid development of my country's industrial strength, the state and enterprises will pay more and more attention to issues such as the working environment and safety of workers; at the same time, with the development trend of "aging" in our society, in the industrial field How to reduce the labor intensity of workers and improve labor efficiency will also become a new hot i...

AI Technical Summary

Problems solved by technology

The motor drive can achieve a more significant boosting effect, but it will be limited by the battery energy endurance, and the motor battery system has a large weight; the passive structure has a light weight and does not need energy supplementation, but the upper limb booster cannot transfer the weight to the ground, so this The boosting effect of similar structures is not significant, and some may even increase the burden on the human body
