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

Abstract

The invention discloses a pneumatic muscle-based upper limb handling assist device, including a main body mechanical structure design, a driver selection and a control method. During the lifting and handling process of the wearer, for the rotation of the waist joint, the load is transmitted to the legs through the structural design, and the counter force of the thigh is used to achieve power assistance; for the shoulder joint, a Jing wheel and claw mechanism is designed to achieve support and assistance; for the elbow joint , using pneumatic muscle plus wire drive to achieve power assistance. The overall mechanism adopts a multi-degree-of-freedom adjustable design, which is in line with ergonomics; the pneumatic muscle is used as the driver to realize the lightweight of the device; the voice module is used to identify the wearer's movement intention, and then control the operation of the power assist device. For industrial production, warehouse handling and other working conditions, it can achieve a better assisting effect on the user's waist, shoulder and elbow joints.

Description

technical field [0001] The invention belongs to the field of assisting devices, in particular to an upper limb handling assisting device based on pneumatic muscles. Background technique [0002] Since the industrial age, the idea of ​​developing a device that combines human intelligence with the kinetic energy of machines to expand human physical capabilities has been a major direction of engineering research. In recent years, with the development of mechatronics engineering, more and more exoskeleton devices have been put into practical experiments and applications. [0003] In the future, with the rapid development of my country's industrial strength, the country and enterprises will pay more and more attention to issues such as the working environment and safety of workers; How to reduce the labor intensity of workers and improve labor efficiency will also become a new hot issue. [0004] At present, the main research on exoskeleton is biased towards lower limbs, and mor...
