AI Technical Summary
Technical Problem
Existing flexible exoskeleton devices cannot provide structural support and auxiliary force simultaneously, resulting in poor practicality.
Method used
The artificial muscle is driven by a combination of pneumatic actuator and cable. The pneumatic actuator is extended or compressed by a pneumatic pressure regulating component, and the cable drive component provides tension, thus achieving bidirectional assistance.
Benefits of technology
It provides greater driving thrust and tension for joint movement, improves the safety of human-computer interaction, and provides sufficient two-way assistance for people with disabilities.

Abstract
This invention discloses a pneumatic-wire hybrid driven artificial muscle, comprising a pneumatic actuator, a pneumatic pressure regulating component, and a wire drive component. The pneumatic pressure regulating component is connected to the pneumatic actuator and is used to regulate the air pressure in the pneumatic actuator to control its extension or compression. The telescopic end of the wire drive component is fixedly connected to the telescopic end of the pneumatic actuator and is used only to control the actuator's compression. The artificial muscle in this invention employs both pneumatic and wire drive. By utilizing the high rigidity of the pneumatic actuator, it can provide a large driving thrust for joint movement. Simultaneously, the wire drive component enables the artificial muscle to provide a large driving pull. The flexible structure effectively ensures the safety of human-machine interaction, providing sufficient bidirectional assistance for disabled individuals wearing this artificial muscle as a drive device.
