Problems solved by technology

Therefore, there is a part of the gas inside the artificial muscle that does not circulate. When the artificial muscle reciprocates for a long time, the temperature of this part of the gas will gradually increase, which seriously affects the service life of the artificial muscle.

Embodiment Construction

[0024] The present invention will be further described below with reference to the drawings and embodiments.

[0025] As shown in Figure 1, a double-opening woven mesh type soft joint artificial muscle includes an inner rubber tube 5, a woven mesh 4 arranged on the outer side of the inner rubber tube 5 along the axial direction, and located at both ends of the inner rubber tube 5 and connected with The end fixing line 2 of the woven net 4 is integrated. The woven net 4 wraps the part of the inner rubber tube 5 between the two ends. The part of the inner rubber tube 5 that is not wrapped by the woven net 4 is used with an external pressure tight line 1 is tightly wound to form a pressure-bearing catheter, and the inner layer of rubber tube 5 is wound with a sealing end compression line 6 outside the adjacent end fixing line 2. The woven net 4 is made of hard material. The woven net 4 is made of a soft material, and an outer rubber tube 3 is arranged outside the inner rubber tube ...

Abstract

The invention discloses a dual-opening mesh grid type flexible joint artificial muscle. The dual-opening mesh grid type flexible joint artificial muscle comprises an inner rubber tube, a mesh grid, end fixing lines and sealed end pressing lines, wherein the mesh grid is arranged on the outer side of the inner rubber tube in the axial direction; the end fixing lines are located at the two ends of the mesh grid and integrated with the mesh grid; the sealed end pressing lines are used for restraining the mesh grid transversely at the two ends; the mesh grid wraps the middle of the inner rubber tube; the two ends, not wrapped with the mesh grid, of the inner rubber tube are densely wound with external pressure-bearing dense lines, so that a pressure-bearing liquid guide tube is formed; and the sealed end pressing lines are arranged close to the end fixing lines and are wound outside the mesh grid to restrain the mesh grid on the inner rubber tube. The dual-opening mesh grid type flexible joint artificial muscle is smoother in connection and not prone to being damaged, and flexible connection between the muscle and a driven object can be achieved.

Description

Technical field [0001] The invention relates to a driving artificial muscle used in the fields of robots, rehabilitation medical equipment, special operation manipulators, automated production lines and the like, in particular to an artificial muscle with soft joints open at both ends. Background technique [0002] Artificial muscles have a large output power to mass ratio. Artificial muscles are widely used in medical rehabilitation equipment and robot joint drive. After the artificial muscle is filled with a certain pressure of gas, it contracts axially and expands radially to produce contraction force. The traditional artificial muscle consists of three parts, the joints at both ends, the inner rubber tube and the outer woven mesh. The connection of the artificial muscle joint part mainly relies on the friction between the joint and the braided mesh and rubber tube. Most of the existing artificial muscles have a single opening, that is, only one joint is used as a ventilatin...
