Embodiment Construction

[0017] Below in conjunction with accompanying drawing and example the present invention is described in further detail. These drawings are all simplified schematic diagrams, which only schematically illustrate the rapid prototyping method of the present invention, and therefore only show the components related to the present invention.

[0018] Such as figure 1 and figure 2 As shown, a stretching type pneumatic artificial muscle of the present invention includes an upper fixed plate 1, an I-shaped joint 3, an upper sliding shaft 4, a pneumatic muscle 5, a fixed rod 6, an upper moving plate 9, and a lower moving plate 10, Lower sliding shaft 11, lower fixed disk 12. Described fixed rod 6 outer surfaces are smooth, and two ends have screw thread, and one end connects upper fixed disc 1, and the other end connects lower fixed disc 12, and four fixed rods 6 and upper fixed disc 1, lower fixed disc 12 form a fixed structure. The pneumatic muscle 5 at the upper end is fixedly co...

Abstract

The invention discloses the stretching type pneumatic artificial muscle. The pneumatic artificial muscle comprises an upper fixing disc, an inner layer rubber tube, an I-shaped connector, an upper sliding shaft, fixed rods, a mesh grid, an outer layer rubber tube, an upper moving disc, a lower moving disc, a lower sliding shaft and a lower fixing disc, wherein the outer surface of the fixed rods are smooth, the two ends of the fixed rods are provided with threads, one ends of the fixed rods are connected with the upper fixing disc, and the other ends of the fixed rods are connected with the lower fixing disc, and the four fixed rods, the upper fixing disc and the lower fixing plate form a fixing structure; the pneumatic muscle is composed of the inner layer rubber tube, an oblique crossingmesh grid and the outer layer rubber tube, the pneumatic muscles at the upper end are fixedly connected with the upper fixing disc and the upper moving disc, and the pneumatic muscle at the lower endis fixedly connected with the lower moving disc and the lower fixing disc; and the pneumatic muscles are inflated and then expands and then drives the moving discs to move in the axial direction. Thestretching type pneumatic artificial muscle is connected between the moving discs and the sliding shafts through the I-shaped connector, so that the complexity of the artificial muscle structure is greatly reduced, the overall structure is more compact, and the stability is high.

Description

technical field [0001] The invention belongs to the field of driving element design, and in particular relates to a tensile type artificial muscle design, in particular adopting an I-shaped joint connection mode, which can provide pulling force and pushing force simultaneously as required while enhancing structural reliability. Background technique [0002] In recent years, artificial intelligence technology has become an important trend in the development of science and technology in the world, and scientists have attached unprecedented importance to the development of robots. In addition to industrial applications, robots have shined in fields such as service, medical care, and disaster relief. As an important part of robot joint drive, the development of artificial muscles restricts the development of robots to a large extent. For example, the Atlas humanoid robot developed by Boston Dynamics in November 2017 has as many joints as humans. It can not only jump over obsta...
