Description

Technical Field

[0001] This invention relates to the field of key robot components technology, and in particular to an ultra-flexible composite cable for intelligent robots. Background Technology

[0002] With the rapid development of intelligent robot technology, higher requirements are being placed on cables, one of the key components. Intelligent robots typically need to perform tasks in complex and dynamic environments, such as industrial assembly, medical services, and home services. These applications require cables to possess extremely high flexibility, bending resistance, torsional resistance, and stable power and signal transmission performance. Especially in robot joints or frequently moving mechanisms, cables must withstand continuous mechanical stress. Improper design can easily lead to internal core displacement, insulation wear, signal interference, or even open circuits, seriously affecting the reliability and service life of the robot. Therefore, developing an ultra-flexible composite cable specifically for intelligent robots not only helps improve the robot's motion flexibility and working accuracy but also ensures the stability of electrical performance during long-term dynamic use, possessing significant engineering application value.

[0003] In practical applications, existing robot cables still have the following shortcomings: 1. The simple stranded or layered structure makes the internal cores prone to relative displacement or loosening under frequent bending or vibration, leading to poor contact, impedance changes, or localized stress concentration, which in turn causes performance degradation or failure. 2. The mixed arrangement of power and control cores, due to insufficient electromagnetic compatibility design, makes high-frequency interference generated during power transmission easily affect the accuracy of control signals, especially in high-speed data transmission scenarios, where the bit error rate increases significantly. 3. Limited flexibility and elastic recovery capabilities make the cables prone to plastic deformation or cracking after long-term use, reducing cable durability. 4. The complex assembly process between components not only increases manufacturing costs but may also lead to delamination or loosening under dynamic loads, affecting the integrity of the overall structure.

[0004] In the field, the performance of cables for robots has been improved through material optimization or structural fine-tuning, such as using highly elastic polymers or adding shielding layers. However, these measures have not fundamentally solved the deficiencies in structural stability and flexibility. Chinese patent CN110752058A discloses a flexible cable for intelligent equipment and its manufacturing process. This solution provides the main support through a central reinforcement member. In the gap formed by the five equally divided power cores and control cores, a central reinforcement member with aviation steel wire rope as its core is set as the tension-bearing main body. Internal sliding is ensured by filling and talc powder. Reinforced PP mesh filler strips coated with talc powder are widely used inside the control core group and during the cable assembly process to provide buffer space for the cores and reduce internal friction to achieve flexibility. A multi-layer sheath and an outer braided layer are used for overall constraint and protection. Through the three-layer structure of the inner sheath, the aramid fiber braided reinforcement layer, and the outer sheath, the cable core is covered, constrained, and tensile-strengthened from the outside. In practical applications, during long-term, high-frequency complex dynamic movements (such as multi-directional bending and torsion at robot joints), the cable core and filler may slip or shift due to the lubrication effect of talcum powder. This leads to decreased cable roundness, structural instability, and consequently, localized stress concentration, accelerating core wear. While the central reinforcement (aviation steel wire rope) can effectively withstand axial tension, its resistance to torsional forces around the axis and radial pressure from the sides is limited. The aramid braided layer primarily enhances axial tensile strength, offering weak constraint against torsion and radial compression. Therefore, in applications requiring multi-dimensional mechanical stress, the cable is prone to twisting deformation or flattening, affecting signal transmission stability and cable lifespan.

[0005] Therefore, how to provide an ultra-flexible composite cable that achieves structural stability while improving flexibility, electromagnetic compatibility, and ease of assembly to meet the urgent needs of intelligent robots for high-performance cables has become a pressing technical problem to be solved. Summary of the Invention

[0006] In view of this, in order to overcome the shortcomings of the prior art, the present invention aims to provide an ultra-flexible composite cable for intelligent robots.

[0007] This invention provides an ultra-flexible composite cable for intelligent robots. The cable includes a central locking frame, multiple radial locking carriers, multiple curved locking walls, an inner sheath, multiple power conductors, multiple control conductors, and an outer sheath. The central locking frame includes a central shaft and multiple locking wings integrally connected to the central shaft. The inner ends of the multiple radial locking carriers are inserted and locked to the inner side of the central shaft. The power conductors are correspondingly arranged between the locking wings of the central locking frame and the radial locking carriers. The control conductors are correspondingly assembled on the radial locking carriers. The curved locking walls are correspondingly arranged between adjacent radial locking carriers. The locking wings of the central locking frame are inserted into the curved locking walls. The inner and outer sheaths are coaxially arranged on the outer side of the curved locking walls.

[0008] Optionally, in the intelligent robot ultra-flexible composite cable of the present invention, multiple locking wings are distributed circumferentially at equal intervals in the circumferential direction of the central shaft, and multiple locking wings are distributed in an array at equal intervals in the axial direction of the central shaft.

[0009] Optionally, the intelligent robot ultra-flexible composite cable of the present invention has a locking wing consisting of a wing rod and a first locking part integrally connected to the outer end of the wing rod. The first locking part is generally arrow-shaped, and the side of the first locking part near the wing rod is arc-shaped. Multiple interlocking slots are arranged in an axial array on the central shaft between adjacent locking wings.

[0010] Optionally, the ultra-flexible composite cable for intelligent robots of the present invention includes a radial locking carrier comprising a radial rod portion, a fixing ring portion integrally connected to the outer end of the radial rod portion, and a second locking portion integrally connected to the inner end of the radial rod portion. A circular carrier portion is integrally connected to the middle of the radial rod portion. The fixing ring portion is generally in the shape of an arc bending inward, and the side of the second locking portion near the radial rod portion is in the shape of an arc bending inward.

[0011] Optionally, the ultra-flexible composite cable for intelligent robots of the present invention has a curved locking wall comprising a locking wall body with an overall fan-shaped cross-section. Multiple locking grooves are arranged in an axial array on the inner wall of the locking wall body, and the locking grooves include integrally connected rectangular grooves and arrow-shaped grooves.

[0012] Optionally, the ultra-flexible composite cable for intelligent robots of the present invention has an inner sheath that is generally hollow cylindrical, and multiple fixing grooves are provided at equal intervals along the axial direction on the inner wall of the inner sheath.

[0013] Optionally, in the intelligent robot ultra-flexible composite cable of the present invention, the second locking parts of multiple radial locking carriers are inserted into the inner side of the central shaft through the insertion slot on the central locking frame, and are locked and fixed by the second locking part which is generally arrow-shaped. The second locking part is symmetrically provided with elastic through holes with an elliptical cross section.

[0014] Optionally, in the intelligent robot ultra-flexible composite cable of the present invention, the power wire cores are arranged one-to-one between the locking fins of the central locking frame and the radial rod of the radial locking carrier, and multiple control wire cores are assembled one-to-one within the annular carrier portion of the radial locking carrier.

[0015] Optionally, in the intelligent robot ultra-flexible composite cable of the present invention, the locking fins of the central locking frame are inserted into the locking grooves of the curved locking wall, the first locking part is locked and fixed in the arrow-shaped groove through the rectangular groove, the cross section of the combination of multiple curved locking walls is circular, the side end faces of two adjacent curved locking walls are closely fitted with the radial rod of the radial locking carrier, and the outer side surfaces of two adjacent curved locking walls match the inner arc of the fixing ring of the radial locking carrier.

[0016] Optionally, in the intelligent robot ultra-flexible composite cable of the present invention, the inner sheath is coaxially disposed on the outside of multiple curved locking walls, and the fixing grooves on the inner side of the inner sheath correspond one-to-one to cover and fix the fixing ring of the radial locking carrier.

[0017] The ultra-flexible composite cable for intelligent robots of the present invention, through the synergistic design of materials and structure, has the following beneficial technical effects: 1. The core structural components are all made of high-molecular elastic materials such as silicone rubber, which have excellent elastic deformation capabilities. Combined with the shape and structural design, they can undergo controllable elastic deformation during insertion and under force, rather than rigid resistance. This gives the entire locking system the characteristics of "combining rigidity and flexibility" in dynamic operation, providing stable locking under normal conditions and allowing necessary component deformation to release stress when bending.

[0018] 2. When the cable bends, stress is distributed to individual locking components. Each component can make minute adaptive adjustments and rotations, transforming localized large-curvature bends into multiple small-angle continuous flexible deformations. This allows for repeated bending at extremely small radii while maintaining overall structural integrity, significantly improving bending fatigue resistance. The excellent deformation resistance and bending fatigue resistance enable the cable to withstand long-term, high-frequency dynamic movements of intelligent robots, significantly delaying performance degradation caused by material aging and structural failure, and greatly extending its service life. The modular component design allows for independent manufacturing of each part followed by precise assembly. The plug-in locking mechanism simplifies the process, improving production efficiency and product consistency.

[0019] 3. The power conductors and control conductors are respectively and fixedly placed in an independent and stable space composed of a locking system, which effectively prevents mutual friction between conductors and friction with the sheath, reduces the risk of short circuits or open circuits caused by mechanical damage, and at the same time, the stable physical layout is also conducive to controlling impedance stability and reducing signal crosstalk.

In the circumferential direction of the central shaft 11, the plurality of locking wings 12 are distributed in a circumferentially spaced manner, and in the axial direction of the central shaft 11, the plurality of locking wings 12 are distributed in an array with equal spacing.

[0027] In this embodiment, the locking wing 12 is composed of a wing rod 121 and a first locking part 122 integrally connected to the outer end of the wing rod 121. The first locking part 122 is generally arrow-shaped, and the side of the first locking part 122 near the wing rod 121 is arc-shaped.

Figure 4 As shown, in this embodiment, the curved locking wall 3 includes a locking wall body 31 with an overall fan-shaped cross-section. Multiple locking grooves 32 are arranged in an axial array on the inner wall of the locking wall body 31. Each locking groove 32 includes an integrally connected rectangular groove 321 and an arrow-shaped groove 322. The rectangular groove 321 matches the wing rod 121 of the locking wing 12, and the arrow-shaped groove 322 matches the first locking part 122 of the locking wing 12.

[0030] Figure 5 This is a schematic diagram of the inner sheath of an ultra-flexible composite cable for intelligent robots according to an exemplary embodiment of the present invention. Figure 5 As shown, in this embodiment, the inner protective layer 4 is a hollow cylinder, and multiple fixing grooves 41 are provided at equal intervals along the axial direction on the inner wall of the inner protective layer 4.

[0031] Figure 6 This is a partial structural example of an ultra-flexible composite cable for intelligent robots according to an exemplary embodiment of the present invention. Figure 7 This is a cross-sectional schematic diagram of an ultra-flexible composite cable for an intelligent robot according to an exemplary embodiment of the present invention.

[0032] It should be noted that in this embodiment, the central locking frame 1, the radial locking carrier 2, the curved locking wall 3, and the inner protective layer 4 are all made of polymer materials with excellent mechanical and physical properties and electrical insulation properties, and have excellent elastic deformation capabilities. For example, they are made of silicone rubber, polypropylene, cross-linked polyethylene, thermoplastic polyurethane elastomer, or other suitable materials. This embodiment does not limit the use of such materials.

[0033] like Figures 1 to 7As shown, in this embodiment, the second locking parts 23 of multiple radial locking carriers 2 are inserted into the inner side of the central shaft 11 through the insertion slot 13 on the central locking frame 1, and are locked and fixed by the arrow-shaped second locking parts 23. As an optional example, the second locking parts 23 are symmetrically provided with elastic through holes 25 with an elliptical cross section, so that the second locking parts 23 can generate elastic deformation more efficiently during the insertion and locking process of the radial locking carriers 2.

[0034] The power conductors 5 are arranged one-to-one between the locking fins 12 of the central locking frame 1 and the radial rods 21 of the radial locking carrier 2. Multiple control conductors 6 are assembled one-to-one within the annular carrier portion 24 of the radial locking carrier 2.

[0035] Curved locking walls 3 are arranged one-to-one between adjacent radial locking carriers 2. The locking fins 12 of the central locking frame 1 are inserted into the locking grooves 32 of the curved locking walls 3. Specifically, the first locking part 122 is locked and fixed in the arrow-shaped groove 322 by a rectangular groove 321. The cross-section of the combination of multiple curved locking walls 3 is circular. The side end faces of two adjacent curved locking walls 3 are tightly fitted with the radial rod part 21 of the radial locking carrier 2. The outer side surfaces of two adjacent curved locking walls 3 match the inner arc of the fixing ring part 22 of the radial locking carrier 2.

[0036] The inner protective layer 4 is coaxially disposed on the outer side of multiple curved locking walls 3, and the fixing grooves 41 on the inner side of the inner protective layer 4 correspond one-to-one with the fixing rings 22 of the radial locking carrier 2 to cover and fix them. The outer protective layer 7 is coaxially disposed on the outer side of the inner protective layer 4. For example, in this embodiment, the inner protective layer 4 is made of a polymer material with excellent flexibility, such as neoprene rubber, and the outer protective layer 7 is made of wear-resistant polyurethane elastomer, polyvinyl chloride, or silicone rubber.

[0037] In this embodiment, the central locking frame 1 is the mechanical core of the entire cable. Its circumferentially and axially distributed locking wings 12 interlock with the locking grooves 32 on the curved locking wall 3, forming multiple anchoring points that are continuously and equidistantly distributed along the cable axis. This upgrades the traditional linear or surface contact to a three-dimensional locking system, effectively resisting the radial and axial shear stresses caused by frequent bending and torsion, and preventing relative slippage and loosening between internal components.

[0038] As a key connecting component, the radial locking carrier 2 has a second locking part 23 at its inner end that passes through the insertion slot 13 of the central locking frame 1 and is locked to the inner side of the central shaft 11, forming a support skeleton radiating outward from the center. This securely restrains the power wire core 5 between the locking wing 12 and the radial rod 21. At the same time, the fixing ring part 22 is tightly covered by the fixing groove 41 on the inner side of the inner sheath 4, forming a complete force chain transmission path from the center of the cable to the inner sheath. This allows external pressure or torque to be evenly distributed across the entire cross section, avoiding stress concentration and greatly improving the cable's resistance to flattening and torsion.

[0039] Multiple curved locking walls 3, supported at intervals by the radial locking carrier 2, combine together to form a complete circular cross-section. Their side end faces are tightly fitted with the radial rod 21, and their outer side faces match the inner arc of the fixing ring 22, forming a tightly meshed circumferential closed structure. This ensures that the cross-sectional shape maintains a high degree of integrity when the cable is deformed under stress, effectively preventing internal space imbalance and core compression caused by local collapse or deformation.

[0040] Figure 8 This is a schematic diagram of the power conductor of an ultra-flexible composite cable for intelligent robots according to an exemplary embodiment of the present invention. Figure 8 As shown, in this embodiment, the power conductor 5 consists of a power conductor 51 and, from the inside out, an inner shielding layer 52, an insulating layer 53, and an outer shielding layer 54 sequentially covering the outside of the power conductor 51. For example, in practical applications, the power conductor 51 is made of tin-plated annealed copper wire, the inner shielding layer 52 is made of semi-conductive cross-linked polyethylene, the insulating layer 53 is made of thermoplastic elastomer, and the outer shielding layer 54 is made of semi-conductive cross-linked polyethylene material.

[0041] Figure 9 This is a schematic diagram of the structure of the control core of an ultra-flexible composite cable for intelligent robots according to an exemplary embodiment of the present invention. Figure 9 As shown, in this embodiment, the control core 6 comprises two symmetrically twisted control wires 61 and a control sheath 62 covering the outside of the control wires 61. The control wires 61 consist of control conductors 611 and a control insulation layer 612 covering the outside of the control conductors 611. The control conductors 611 are made of tin-plated copper wire bundles, the control insulation layer 612 is made of silicone rubber or flexible polyvinyl chloride, and the control sheath 612 is made of low-hardness TPE (thermoplastic elastomer), such as thermoplastic polyurethane elastomer.

[0042] In practical applications, the ultra-flexible composite cable for intelligent robots in this embodiment of the invention, through the synergistic design of materials and structure, has the following beneficial technical effects: 1. The core structural components are all made of high-molecular elastic materials such as silicone rubber, which have excellent elastic deformation capabilities. Combined with the shape and structural design, they can undergo controllable elastic deformation during insertion and under force, rather than rigid resistance. This gives the entire locking system the characteristics of "combining rigidity and flexibility" in dynamic operation, providing stable locking under normal conditions and allowing necessary component deformation to release stress when bending.

[0043] 2. When the cable bends, stress is distributed to individual locking components. Each component can make minute adaptive adjustments and rotations, transforming localized large-curvature bends into multiple small-angle continuous flexible deformations. This allows for repeated bending at extremely small radii while maintaining overall structural integrity, significantly improving bending fatigue resistance. The excellent deformation resistance and bending fatigue resistance enable the cable to withstand long-term, high-frequency dynamic movements of intelligent robots, significantly delaying performance degradation caused by material aging and structural failure, and greatly extending its service life. The modular component design allows for independent manufacturing of each part followed by precise assembly. The plug-in locking mechanism simplifies the process, improving production efficiency and product consistency.

[0044] 3. The power conductors and control conductors are respectively and fixedly placed in an independent and stable space composed of a locking system, which effectively prevents mutual friction between conductors and friction with the sheath, reduces the risk of short circuits or open circuits caused by mechanical damage, and at the same time, the stable physical layout is also conducive to controlling impedance stability and reducing signal crosstalk.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention.
