Description

Artificial muscle device Technical Field The present invention relates to an artificial muscle device. Background Patent document 1 describes a method for contracting an artificial muscle using an electromagnet, wherein a link is connected in a chain-like manner in a plurality of stages to form a chain-like body, and the length of the chain-like body is contracted while controlling the contraction force. Patent document 1 Japanese patent laid-open No. 08-182698 Patent document 2 Japanese patent application laid-open No. 2021-7667 Disclosure of Invention In the artificial muscle contraction method of patent document 1, the weight of the joint is large, and excessive driving energy is required. In addition, there is also a hidden danger that electromagnets contact each other when the artificial muscle is contracted. The present invention has been made to solve the above-described problems, and an object of the present invention is to provide an artificial muscle device that can be reduced in weight. An artificial muscle device according to one aspect of the present invention includes a braided sleeve, an electromagnet disposed inside the braided sleeve and at one end in a telescoping direction, the electromagnet or the magnet disposed inside the braided sleeve and at the other end in the telescoping direction, and a guide that suppresses movement of the electromagnet or the magnet in the telescoping direction. In the artificial muscle device, the electromagnet disposed at the one end portion may be opposed to the electromagnet or the magnet disposed at the other end portion with a space interposed therebetween. In the artificial muscle device, the guide may include a mesh of wires woven so as to constitute the woven sleeve. Effects of the invention The present invention can provide an artificial muscle device that can be reduced in weight.

Detailed Description The specific configuration of the present embodiment will be described below with reference to the drawings. The following description shows preferred embodiments of the present invention, but the scope of the present invention is not limited to the following embodiments. Moreover, not all the structures described in this embodiment are necessary as means for solving the problems. The following description and drawings are omitted and simplified as appropriate for clarity of illustration. In the drawings, the same elements are denoted by the same reference numerals, and repetitive description thereof will be omitted as necessary. < Embodiment 1> The artificial muscle device in this embodiment will be described. The artificial muscle device of the present embodiment relates to a method for driving an artificial muscle using a braided sleeve, and an artificial muscle device. The artificial muscle device of the present embodiment is provided with an electromagnet in a braided sleeve, for example. The artificial muscle device according to the present embodiment contracts the braided tube by an electromagnet. The artificial muscle device using a braided sleeve of patent document 2 uses air pressure to contract the braided sleeve. Therefore, the artificial muscle device of patent document 2 requires a compressor for delivering air pressure to be provided outside, and the device becomes bulky. Further, the artificial muscle device of patent document 2 has a problem that it cannot be driven due to air leakage from the connection portion. Further, it is considered that the artificial muscle is driven by contraction of a bag in which the grease composition is placed in the braided sleeve, but this form has a risk of grease in the braided sleeve leaking out of the bag. Moreover, the weight of the grease becomes equivalent to the weight of the grease, and more driving energy is required. In order to solve the above problems, the present embodiment provides a small artificial muscle device including a braided sleeve, an electromagnet, and the like. Fig. 1 and 2 are block diagrams illustrating an artificial muscle device 1 according to embodiment 1. As shown in fig. 1 and 2, the artificial muscle device 1 of the present embodiment includes a braided sleeve 10, an electromagnet 21, and an electromagnet 22. Fig. 1 illustrates the structure of the artificial muscle device 1 in a non-energized state in which the electromagnets 21 and 22 a
