Intelligent hand device driven by pneumatic muscle

Abstract

The invention relates to an intelligent hand device driven by pneumatic muscle. The intelligent hand device includes a palm mechanism, a thumb mechanism and four finger mechanisms. The palm mechanismincludes a palm body, a palm cover plate, a thumb sliding block, finger sliding blocks, and the pneumatic muscle which controls the movement of the sliding blocks; the thumb mechanism is internally provided with a thumb connecting rod mechanism, the thumb connecting rod mechanism is connected with the thumb sliding block in the palm mechanism, and the thumb mechanism is driven by the thumb slidingblock and the thumb connecting rod mechanism to realize three degrees of freedom of rotation under the drive of the pneumatic muscle; finger connecting rod mechanisms are arranged in the finger mechanisms, and the finger connecting rod mechanisms are connected with the finger sliding blocks in the palm mechanism, the finger mechanisms are driven to realize two degrees of freedom of rotation through the finger sliding blocks and the finger connecting rod mechanism under the drive of the pneumatic muscle. Compared with the prior art, the intelligent hand device has the advantages of simple mechanism, light weight, convenient assembly and maintenance, reduced power loss and the like.

Description

technical field [0001] The invention relates to the field of medical rehabilitation, in particular to an intelligent hand device driven by pneumatic muscles. Background technique [0002] In recent years, due to accidents such as safety accidents and traffic accidents, the number of limb amputee patients among disabled patients is constantly increasing. According to statistics, the number of disabled people in mainland China has reached more than 60 million, about 5% of the overall population, of which about 30%-40% are upper limb disabled, and about 4 million people have amputated forearm. Certain deficiencies in the body bring inconvenience to their life, study, and work, and subsequently cause various psychological and physical obstacles. [0003] For patients with missing limbs, most of the current electric prosthetic hands are active prosthetic hands and myoelectric signal prosthetic hands. In foreign countries, the German Vincent company and the British RSL Steeper c...

Problems solved by technology

[0004] At present, most of the rehabilitation devices are driven by pure motors, the mechanism is complicated, the device is heavy, and takes up a lot of space; and the motor movement will shake, causing the smart hand to work inaccurately
