Air elastic energy storage devices are primarily used for drive conversion, such as in cylinders. Furthermore, the preparation of high-performance artificial muscle microfibers is primarily used in intelligent fabrics and humanoid robots.

[0004] In order to help reduce the difficulty of applying elastic cable technology and provide new solutions for the application of elastic cables, it is necessary to develop a system that automatically controls the restraint and release of the restraint device through changes in tension.

DETAILED DESCRIPTION

[0027] To make the objectives, technical solutions, and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other implementations obtained by those of ordinary skill in the art without inventive effort are within the scope of protection of the present invention.

[0028] In the description of the present invention, it should be noted that, unless otherwise specified, the term "plurality" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front," "rear," "head," "tail," etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are intended only to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific direction, be constructed, or operate in a specific direction, and therefore should not be construed as limiting the present invention. Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0029] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; and direct or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of these terms in the present invention depending on the specific circumstances.

[0030] The present invention provides a tension-compression controlled node constraint device system, comprising a first constraint member 1, a second constraint member 2, an auxiliary member 3, and a traction member 4, wherein the first constraint member 1 is connected to the second constraint member 2, and the telescopic state of the second constraint member 2 can control the constraint or release state of the first constraint member 1, and the elastic constraint of the first constraint member 1 and the second constraint member 2 changes, so that the elastic constraint effect of the second constraint member 2 in a certain direction is converted into the elastic constraint of the first constraint member 1 in another direction and performs energy storage or release, and the auxiliary member 3 is connected to the second constraint member 2;

[0031] The elastic constraint mentioned above can refer to visible elastic deformation or changes in the force field. The elastic constraint is formed when the tension-compression controlled node constraint device system is subjected to external forces. At this time, the tension-compression controlled node constraint device system can adapt to the size, shape, and strength of the system.

[0032] There are two ways to connect the auxiliary member 3 and the second restraining member 2. The first connection method is that the traction member 4 bypasses the auxiliary member 3 and is connected to the second restraining member 2. The external force pulling the traction member 4 can change the extension state of the second restraining member 2. The first connection method has a faster response speed, but it is inconvenient to set a delay.

[0033] The second connection method is that the traction member 4 is connected to the auxiliary member 3. The external force pulling the traction member 4 can make the auxiliary member 3 rotate relative to the second constraint member 2 and change the telescopic state of the second constraint member 2. The second connection method is converted by a pressure-rotation motion, which is more conducive to setting the delay control. The present invention provides a tension-compression controlled node constraint device system, in which an elastic cable is connected to the traction member 4. When the elastic cable changes the tension of the traction member 4, the traction member 4 will cause the second constraint member 2 to be subjected to tension through the auxiliary member 3, and then undergo a change in stretching or contraction, so that the first constraint member 1 can be controlled to be telescopic under the change of the telescopic state of the second constraint member 2, thereby realizing that the elastic cable can automatically control the constraint or release of the first constraint member 1 through the change of tension, solving the technical problem of the elastic cable in the prior art that the constraint and release system of the constraint device cannot be automatically controlled by the change of tension.

[0034] As an optional embodiment, the specific structure of the first connection method between the auxiliary member 3 and the second restraint member 2 is: the second restraint member 2 includes a first telescopic frame 21 and a first elastic member 22, the first elastic member 22 is located in the first telescopic frame 21, one end of the first elastic member 22 is connected to the first end corner 211 of the first telescopic frame 21, the auxiliary member 3 is connected to the second end corner 212 of the first telescopic frame 21, and the traction member 4 bypasses the auxiliary member 3 and is connected to the other end of the first elastic member 22; the first telescopic frame 21 can be a diamond structure, the first end corner 211 and the second end corner 212 are located on a diagonal line of the diamond structure, and the first telescopic frame 21 can be other shapes.

[0035] The auxiliary component 3 includes a guide wheel 31 and a connecting frame 32. The guide wheel 31 is rotatably connected to the connecting frame 32. The connecting frame 32 is connected to the second end angle 212. The traction component 4 bypasses the guide wheel 31 and is connected to the other end of the first elastic component 22. The guide wheel 31 is used to change the pulling direction of the traction component 4. When the tension of the elastic cable on the traction member 4 gradually increases, the traction member 4 will pull the first elastic member 22, thereby driving the first end angle 211 and the second end angle 212 to approach each other, thereby compressing the longitudinal direction of the first telescopic frame 21, and the transverse direction of the first telescopic frame 21 will be extended, thereby stretching the third telescopic frame 11, thereby elastically stretching and constraining the second elastic member 12, so that the third telescopic frame 11 is externally constrained; when the tension of the elastic cable on the traction member 4 gradually decreases, the first elastic member 22 will be released, thereby the first end angle 211 and the second end angle 212 are moved away from each other, thereby extending the longitudinal direction of the first telescopic frame 21, and compressing the transverse direction of the first telescopic frame 21, thereby compressing the third telescopic frame 11, thereby elastically retracting the second elastic member 12, so that the third telescopic frame 11 is released from external constraints.

[0036] As an optional embodiment, the second connection mode of the auxiliary member 3 and the second restraining member 2 is specifically structured as follows: the second restraining member 2 includes a second telescopic frame 23 and a threaded rod 24, the threaded rod 24 passes through the second telescopic frame 23, the third end corner 231 and the fourth end corner 232 on the second telescopic frame 23 are both threadedly connected to the threaded rod 24, and the end of the threaded rod 24 is connected to the auxiliary member 3, the second telescopic frame 23 can be a diamond structure, the third end corner 231 and the fourth end corner 232 are located on a diagonal line of the diamond structure, and the second telescopic frame 23 can be other shapes;

[0037] The third end angle 231 and the fourth end angle 232 move in opposite directions. When the threaded rod 24 rotates, the third end angle 231 and the fourth end angle 232 move toward or away from each other.

[0038] The auxiliary component 3 includes a movable plate 33, a movable rotating rod 34, a first rope 35, a second rope 36 and a reset mechanism 37.

When the tension of the elastic rope on the traction member 4 gradually increases, the traction member 4 will pull the movable plate 33 to move along the movable rotating rod 34 in the direction away from the second restraining member 2, and the reset mechanism 37 will be compressed, and then the first rope 35 and the second rope 36 will reduce the number of turns wrapped around the movable rotating rod 34, thereby driving the movable rotating rod 34 to rotate, thereby driving the threaded rod 24 to rotate, and the rotation of the threaded rod 24 will drive the third end angle 231 and the fourth end angle 232 to move toward each other, thereby compressing the longitudinal direction of the second telescopic frame 23, and the transverse direction of the second telescopic frame 23 will be extended, thereby stretching the third telescopic frame 11, thereby elastically stretching the second elastic member 12, so that the third telescopic frame 11 forms External constraint; when the tension of the elastic rope on the traction member 4 gradually decreases, the compression elastic force of the reset mechanism 37 will prompt the movable plate 33 to move along the movable rotating rod 34 in the direction close to the second constraint member 2, and the first rope 35 and the second rope 36 will increase the number of turns around the movable rotating rod 34. At the same time, the movable rotating rod 34 rotates in the opposite direction, thereby driving the threaded rod 24 to rotate in the opposite direction. The rotation of the threaded rod 24 will drive the third end angle 231 and the fourth end angle 232 to move away from each other, thereby extending the longitudinal direction of the second telescopic frame 23, and compressing the transverse direction of the second telescopic frame 23, thereby compressing the third telescopic frame 11, and the second elastic member 12 elastically retracts, so that the third telescopic frame 11 is released from external constraints.
