Embodiment

[0047] The bag type artificial pneumatic muscle that this application relates to is made up of braided network tube 2, air bag 1, two connecting joint components and sponge. The connecting joint that can be communicated with air is made up of the nail 4 with the hole, the tapered top with the hole, the tapered sleeve 10, and the joint with the hole 6. The fully closed connecting joint is made up of a push nail 7 without holes, a conical top, a second conical sleeve and a joint 9.

[0048] The airbag 1 is hollow, and is inflated therein through an airway tube 3 . The air guide tube 3 is integrated with the air bag 1, and is connected with the inflatable device through the hole in the connecting joint assembly communicating with the air. The two ends of the air bag 1 are respectively fixed by the nail 4 with the hole and the tapered top and the nail 7 with the tapered top.

[0049] The nail 4 with a hole is used to fix the air bag 1 and pass the airway tube 3 . The pin 4 with...

Abstract

The invention belongs to the technical field of bionic drivers, particularly relates to a pneumatic muscle, and solves the problems of complicated structure and high production cost of an existing pneumatic muscle. The pneumatic muscle comprises an air bag, a woven mesh pipe is arranged on the outer side of the air bag, the air bag is connected with one end of the woven mesh pipe through a first connector component and connected with the other end of the woven mesh pipe through a second connector component, an air guide pipe is arranged in the air bag, the first connector component comprises an inflatable channel, and the air guide pipe penetrates the inflatable channel. The pneumatic muscle is a capsule-type artificial pneumatic muscle. Compared with an existing pneumatic muscle, an air bag structure of the capsule-type artificial pneumatic muscle is inflated and deformed, a space without needing to be inflated is formed in the middle of an inflated air bag, compressed gas is saved bythe structure, pressure applied onto the air bag is reduced, response time is shortened, and working efficiency is improved.

Description

technical field [0001] The application belongs to the technical field of bionic actuators, and in particular relates to a pneumatic muscle. Background technique [0002] The wave of population aging in the 21st century will sweep across the world and bring severe challenges to social development. As of 2018, my country's elderly population over the age of 60 will exceed 250 million. Due to the decline of their own muscle strength, the elderly have varying degrees of decline in walking ability. In order to improve the walking status of the elderly and prevent the elderly from being injured due to falls, equipment for the purpose of assisting behavior has appeared, among which exoskeleton is the more popular walking aid. Because rigid exoskeletons limit the freedom of the human body, flexible exoskeletons have become a research hotspot. The flexible exoskeleton needs a flexible driver to provide power, and pneumatic muscles are a good choice. Compared with heavy rigid actua...
