[0025] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0026] Reference below Figures 1-4 A cable according to an embodiment of the present invention is described.

[0027] The present invention proposes a large deformation composite cable based on the cooperative deformation of an elastomer, the large deformation composite cable includes a cable body 10 and an elastomer 30, the cable body 10 includes a first connecting part 11, a second connecting part 12 and a deformation part 13; the first connecting part 11 and the second connecting part 12 are suitable for connecting the cable installation anchor to bear and transmit tension; the deformation part 13 connects the first connecting part 11 and the second connecting part 12; the cable body 10 is constructed in multiple parts, and the large deformation composite cable forms a force axis when subjected to tension; the multiple cable bodies 10 are arranged at circumferential intervals about the force axis; the deformation part 13 protrudes in a plane perpendicular to the force axis, and the multiple deformation parts 13 form a deformation cavity 20 around the force axis; the elastomer 30 is arranged in the deformation cavity 20, and the deformation part 13 is suitable for deforming and squeezing the elastomer 30 when the large deformation composite cable is subjected to tension.

[0028] According to the large-deformation composite cable of the present application, the deformation portion 13 protrudes in a plane perpendicular to the force-bearing axis, and multiple deformation portions 13 form a deformation cavity 20 around the force-bearing axis. In this embodiment, when the first connection portion 11 and the second connection portion 12 of the large-deformation composite cable are subjected to force, the tension is transmitted to the deformation portion 13. The deformation portion 13 has a tendency to contract into the deformation cavity 20 under the action of the tension and simultaneously elongate along the force-bearing axis. Therefore, the large-deformation composite cable has good deformation capacity and can undergo significant deformation under the action of tension. The deformation improves the elongation performance of the large-deformation composite cable, thereby improving the tensile performance of the large-deformation composite cable, overcoming its brittleness and preventing it from being directly broken, making the large-deformation composite cable suitable for working conditions requiring high deformation capacity. At the same time, the elastomer 30 is arranged in the deformation cavity 20. When the deformation part 13 shrinks inward, it will squeeze the elastomer 30, and the elastomer 30 will deform cooperatively. At the same time, the elastic force of the elastomer 30 reacts to the deformation part 13, which can inhibit its inward shrinkage to a certain extent, slow down its deformation, avoid sudden changes in the large deformation composite material cable, increase the stability of the large deformation composite material cable, and improve the load-bearing capacity of the large deformation composite material cable during the deformation process under the condition of certain deformation capacity, so that it is suitable for more working conditions.

[0029] It should be noted that in the related art, the deformation capacity of the composite cable generally only comes from the elastic deformation of the material itself. The elastic deformation capacity of the fiber-reinforced composite materials commonly used for cables is relatively small. For example, the common carbon fiber reinforced composite materials have an elastic deformation capacity of only 1%-2%. However, the present application improves the structure of the composite cable and combines the elastic body 30 for coordinated deformation, so that the entire composite cable can achieve a larger deformation amount. In some embodiments, the deformation amount can reach 5%-10%. Therefore, the composite cable of the present application has a large deformation capacity and is a large deformation composite cable.

[0030] According to the large-deformation composite cable of the present application, due to the presence of the deformation cavity 20, the large-deformation composite cable has excellent deformation capacity. The deformation can improve the elongation and tensile properties of the large-deformation composite cable, thereby preventing it from being directly broken. It can be applied to working conditions with high deformation capacity requirements. At the same time, the cooperative deformation of the elastomer can delay the deformation process, increase the stability of the large-deformation composite cable, and also improve the load-bearing capacity of the large-deformation composite cable during the deformation process. The large-deformation composite cable of the present application has excellent stability and reliability, and can meet the requirements of cable deformation capacity in specific application fields.

[0031] According to some embodiments of the present application, the elastic body 30 is formed with a recess 31 that cooperates with the deformation portion 13, and at least a portion of the deformation portion 13 is located in the recess 31 to limit the circumferential movement of the deformation portion 13 relative to the elastic body 30 along the force axis.

[0032] In this embodiment, since the elastic body 30 is disposed in the deformation cavity 20 surrounded by the deformation portion 13, the elastic body 30 and the deformation portion 13 are at least partially in contact with each other. Figure 2 As shown, by providing a recess 31 and placing at least a portion of the deformation portion 13 in the recess 31, the circumferential movement of the deformation portion 13 relative to the elastic body 30 along the force axis can be limited, thereby preventing the deformation portion 13 from slipping and preventing the elastic body 30 from detaching from the gap between the multiple deformation portions 13 to form a large deformation composite cable.

[0033] According to some embodiments of the present application, the elastomer 30 is provided with multiple pressure gaskets corresponding one-to-one to the deformation part 13, and each pressure gasket is arranged between the elastomer 30 and one of the multiple deformation parts 13, so as to be suitable for bearing the pressure applied by the deformation part 13 and dispersing it to the elastomer 30.

[0034] Since the contact area between the deformable portion 13 and the elastic body 30 is limited, the pressure exerted by the deformable portion 13 on the elastic body 30 is relatively concentrated. There is a possibility that the pressure in the contact portion is too high and damages the elastic body 30, and it is not conducive to the elastic deformation of the elastic body 30 as a whole. To address this problem, in this embodiment, a pressure gasket (not shown in the drawings) is provided between the elastic body 30 and the deformable portion 13. The pressure gasket is subjected to the pressure of the deformable portion 13 and then transmits the pressure to the elastic body 30, so that the force on the elastic body 30 can be dispersed, thereby making the deformation of the elastic body 30 more uniform. In this embodiment, there is no restriction on the shape of the pressure gasket, but the contact area between the pressure gasket and the elastic body 30 will affect the effect of pressure dispersion. In practice, a specific design can be made accordingly. In some embodiments, the above-mentioned recess 31 may be provided with a pressure gasket, which is connected to the elastomer 30, and the deformation portion 13 abuts against the pressure gasket; the pressure gasket and the elastomer 30 may be connected in a variety of ways such as embedding, bonding, etc., but it should be noted that the connection should not restrict the deformation of the elastomer 30 to ensure that the large deformation composite cable can deform normally.

[0035] It should be noted that the elastic body 30 in the present application can be constructed as an elastic material piece formed by a hard elastic material to adapt to the shape of the deformation cavity 20, or it can be constructed as an elastic structural piece with elastic properties such as a spring.

[0036] According to some embodiments of the present application, the large-deformation composite cable further includes a damping element disposed within the elastic body 30. In this embodiment, when the large-deformation composite cable vibrates under the action of external environmental forces, the damping element can reduce vibrations in the overall structure of the large-deformation composite cable, thereby improving the stability and adaptability of the large-deformation composite cable.

[0037] In addition, the elastic body 30 of this embodiment is combined with the damping element, which can make the stiffness and deformation capacity of the elastic body 30 variable and controllable. By changing the elastic body 30 and the damping element, the overall performance of the large deformation composite cable can be adjusted.

[0038] In this embodiment, the damping force direction of the damping member can be set to be directly opposite to the deformation portion 13, so as to better exert the damping effect.

[0039] In some embodiments, the elastic body 30 is constructed as a plurality of springs radially spaced about the force-bearing axis, each spring corresponding to a deformable portion 13. The inner diameter ends of the multiple springs are connected, and the outer diameter end of each spring can directly abut the deformable portion 13 or the pressure washer, or can abut the deformable portion 13 or the pressure washer through an elastic coating. The springs withstand the pressure applied by the deformable portion 13 along its elastic direction and react to the deformable portion 13 through the elastic force, thereby better exerting the elastic effect of the elastic body 30. Furthermore, the outer sides of the multiple springs can be coated with an elastic coating to facilitate spring installation and use, while also improving the coordination of the deformation of the multiple springs.

[0040] According to some embodiments of the present application, the cable body 10 is constructed as a fiber-reinforced composite material part, which includes fibers, and the fibers are constructed as a plurality of fibers extending along the force axis, and at least part of the fibers protrude in a direction perpendicular to the force axis. In this embodiment, the cable body 10 is constructed as a fiber-reinforced composite material part, and the fiber-reinforced composite material is a composite material formed by laminating, molding or pultruding a reinforcing fiber material, such as glass fiber, carbon fiber, aramid fiber, etc., with a matrix material. Specifically, the cable body 10 is a structure having multiple fiber layers formed by curing a unidirectional fiber prepreg according to a prefabricated template. It should be noted that the unidirectional fiber prepreg is a composite material made by processing fiber bundles and resin through processes such as coating, hot pressing, cooling and laminating. The fibers extend in the same direction as the cable body 10. This is manifested by the fibers extending in the direction of force applied at the first or second connecting portion 11, 12, and bulging perpendicularly to the direction of force applied at the deformable portion 13, extending along the deformable portion 13's morphological direction. When the large-deformation composite cable is subjected to force, the tension is transmitted along the fiber extension direction. The cable body 10 of the large-deformation composite cable in this embodiment exhibits excellent mechanical properties, and the curing process ensures consistent processing.

[0041] According to some embodiments of the present application, each cable body 10 is made of a plurality of twisted strands, each of which is constructed as a fiber-reinforced composite material comprising a plurality of fibers, with the fibers of each strand extending along the strand's extension direction. The cable body 10 of this embodiment can improve the performance and range of use of large-deformation composite cables.

[0042] According to some embodiments of the present application, a plurality of deformation cavities 20 are configured, spaced apart along the force-bearing axis. In this embodiment, the provision of multiple deformation cavities 20 enables the large-deformation composite cable to have multiple deformation sections. The deformation capabilities of these multiple deformation sections are superimposed, enabling the large-deformation composite cable to have a greater deformation capacity and thereby enhancing the tensile strength of the large-deformation composite cable. Furthermore, the provision of multiple deformation cavities 20 in this embodiment disperses the deformation to each deformation section, reducing the deformation pressure of a single deformation section. This also reduces the processing and installation pressure of a single deformation section, thereby improving the stability and reliability of the large-deformation composite cable structure.

[0043] According to some embodiments of the present application, the large deformation composite cable also includes a restraint 40, which forms a limiting hole 44. The limiting holes 44 are constructed to correspond one to one with the cable body 10. A portion of each first connection part 11 or a portion of each second connection part 12 is accommodated in one of the multiple limiting holes 44 to be suitable for converging multiple first connection parts 11 or multiple second connection parts 12.

[0044] In this embodiment, the large-deformation composite cable has two connecting ends suitable for connection to an anchor. Each connecting end is composed of multiple first connecting portions 11 or multiple second connecting portions 12. The load-bearing axis of the large-deformation composite cable runs through the center of the two connecting ends. By providing restraints 40 at the two connecting ends, the multiple first connecting portions 11 or multiple second connecting portions 12 can be converged together. During convergence, the protrusion of each deformable portion 13 is kept radially outward along the load-bearing axis to form a deformation cavity 20.

[0045] In this embodiment, when a large-deformation composite cable is subjected to force at both ends, the tension is distributed to each cable body 10. The deformable portion 13 of the cable body 10, under the tensile force of the first connecting portion 11 and the second connecting portion 12, stretches and deforms along the force axis, squeezing the elastic body 30. The elastic body 30 is simultaneously squeezed and deformed by multiple deformable portions 13. Furthermore, the multiple cable bodies 10 can be constructed identically and arranged symmetrically about the force axis. When a large-deformation composite cable is subjected to force, each cable body 10 has the same deformation capacity, enabling coordinated and synchronized deformation. This ensures uniform force on each deformable portion 13 and ensures stability during the cable deformation process.

[0046] In an embodiment having multiple deformable cavities 20, each cable body 10 further includes multiple intermediate connecting portions, each of which is disposed between two adjacent deformable cavities 20 and connects two deformable portions 13 corresponding to two adjacent deformable cavities 20. To ensure stable connection between the multiple cable bodies 10 between adjacent deformable cavities 20, a restraining member 40 is disposed between adjacent deformable cavities 20 to constrict the corresponding intermediate connecting portions of the multiple cable bodies 10.

[0047] According to some embodiments of the present application, the restraining member 40 includes a first component 41, a second component 42, and a fastener 43. The first component 41 is formed with a first limiting groove, and the second component 42 is formed with a second limiting groove. The first limiting groove and the second limiting groove cooperate to form a limiting hole 44. The first component 41 and the second component 42 are adapted to move closer to or farther away from each other to change the size of the limiting hole 44. The fastener 43 is disposed on the first component 41 and / or the second component 42, and is adapted to connect the first component 41 and the second component 42 and to adjust the spacing between the first component 41 and the second component 42. In this embodiment, the limiting hole 44 formed by the cooperation of the first component 41 and the second component 42 limits the first connecting portion 11 or the second connecting portion 12, preventing the plurality of cable bodies 10 from dispersing when the large-deformation composite cable is subjected to stress, thereby ensuring the stability of the large-deformation composite cable structure. By adjusting the distance between the first component 41 and the second component 42 through the fastener 43, the size of the limiting hole 44 can be adjusted, so that the radial clamping force on the first connection part 11 or the second connection part 12 along the limiting hole 44 can be adjusted to ensure the limiting effect of the limiting hole 44, while facilitating the separation or combination of the first limiting groove and the second limiting groove so that the first connection part 11 or the second connection part 12 can be placed in the limiting hole 44.

[0048] According to some embodiments of the present application, at least one of the first component 41 and the second component 42 is constructed in an annular shape centered on the force-bearing axis, and a plurality of limiting holes 44 are arranged at intervals along the circumference of the force-bearing axis. In this embodiment, by arranging the limiting holes 44 at intervals along the circumference of the force-bearing axis, the relative distance between each cable body 10 and the force-bearing axis is the same, which can ensure that the force on the multiple deformable parts 13 is uniform. Furthermore, the limiting holes 44 can be constructed to be evenly spaced about the force-bearing axis to achieve symmetry between the multiple cable bodies 10 about the center of the force-bearing axis. When the large-deformation composite cable is subjected to force, each cable body 10 can deform in a coordinated manner, making the overall force on the elastic body 30 more uniform, thereby ensuring the stability of the deformation process of the large-deformation composite cable.

[0049] In some embodiments, as Figure 4As shown, the first component 41 is constructed as a cylindrical member, and a plurality of first limiting grooves extending in the axial direction are provided at circumferential intervals on the first component 41; the second component 42 is constructed as an annular member, and a plurality of second limiting grooves extending in the axial direction are provided at circumferential intervals on the inner wall of the second component 42; the first limiting grooves correspond one-to-one with the second limiting grooves, and cooperate to form a limiting hole 44. To facilitate the assembly of the first connecting portion 11, the second connecting portion 12, and the limiting hole 44, the second component 42 is constructed as a combination of two semi-annular members, which are arranged around the first component 41. The two ends of the semi-annular members are each provided with a radially extending ear plate. The corresponding set of ear plates of the two semi-annular members are connected by a fastener 43. By adjusting the spacing between the two semi-annular members, the fastener 43 can adjust the radial spacing between the first component 41 and the second component 42, thereby changing the size of the limiting hole 44. The fastener 43 can be configured as a bolt or a rivet for easy installation and use.
