Description

Technical Field

[0001] The utility model relates to the technical field of wires and cables, and in particular to a data transmission cable for dynamic application of a humanoid robot body. Background Art

[0002] Humanoid robots, also known as humanoid robots or humanoid robots, are robots with humanoid form and functions. They possess not only anthropomorphic limbs, movements, and operational skills, but also perception, learning, and cognitive abilities. Humanoid robots have broad development prospects and a wide range of applications. With continuous technological advancements and decreasing costs, they are playing a vital role in the following areas: 1. Participating in hazardous production processes, improving efficiency and safety; 2. Carrying out scientific research, disaster relief, security inspections, and other tasks; 3. Comprehensively integrating into people's lives, from domestic services to medical assistance.

[0003] As carriers of power and data signals, cables for humanoid robots must also meet higher performance requirements, including bending resistance, torsion resistance, and mobility resistance. Existing data transmission cables for dynamic robot applications have poor tensile strength, overall flexibility, and bending adaptability, making them unsuitable for the complex and long-term movements required of humanoid robots. Furthermore, existing cables have poor strength and wear resistance, and weak anti-interference capabilities. Long-term bending and torsion of existing data transmission cables for dynamic robot applications can lead to fatigue and breakage, making them unable to meet the data transmission needs of dynamic robot applications. Utility Model Content

[0004] In order to solve the problems existing in the background technology, the utility model provides a humanoid robot body dynamic application data transmission cable.

[0005] The technical solution adopted in this utility model is:

[0006] The utility model comprises a signal transmission core wire, a filling strip, an aluminum-plastic composite tape, a tinned copper foil wire braided layer and a PUR outer sheath; the filling strip is located in the center of the cable, and four signal transmission core wires are arranged around the filling strip as the center to form a star-twisted cable, and the aluminum-plastic composite tape is coated on the outside of the cable, the aluminum-plastic composite tape is coated on the outside of the tinned copper foil wire braided layer, and the tinned copper foil wire braided layer is coated on the outside of the PUR outer sheath.

[0007] The signal transmission core wire mainly consists of a tinned copper conductor and an FEP insulating material wrapped around the tinned copper conductor.

[0008] The tinned copper conductor adopts IEC60228 class 6 tinned copper wire.

[0009] The filling strip is mainly composed of Kevlar fiber and thermoplastic elastomer coated on the outside of the Kevlar fiber.

[0010] The tinned copper foil wire braided layer is braided by weaving tinned copper foil wire.

[0011] The PUR outer sheath is made of PUR.

[0012] The beneficial effects of the utility model are as follows:

[0013] 1. As an improvement to the present invention, the use of FEP insulation material has been demonstrated. FEP possesses high tensile strength, capable of withstanding the various mechanical stresses experienced by humanoid robots in their complex movements. Its excellent wear and fatigue resistance also ensures the cable maintains excellent performance stability during long-term use. Furthermore, FEP's low dielectric constant provides high transmission stability when used as insulation for signal transmission cables, enhancing both insulation performance and signal transmission stability.

[0014] 2. The PUR sheath is constructed from PUR, a material with excellent wear resistance. This superior wear resistance ensures that PUR-sheathed cables maintain a long service life even under the harsh conditions of bending, twisting, and friction found within the confined spaces of humanoid robots. The PUR sheath also offers excellent oil and water resistance: The robot's inner walls are generously coated with lubricant, minimizing cable friction with the robot's inner walls. This oil resistance improves the sheath's durability. Excellent mechanical properties: The PUR sheath's excellent flexibility and elasticity allow PUR-sheathed cables to bend easily within humanoid robots, preventing breakage or twisting. Furthermore, the PUR sheath's toughness and elasticity allow it to adapt to the tighter bend radius within the confined spaces of humanoid robots. The PUR outer sheath, with its exceptional wear, corrosion, and weather resistance, provides long-term, reliable protection for the cable.

[0015] Overall, the utility model features an ingenious structural design and a rationally arranged data signal core distribution. The FEP insulation material possesses high mechanical properties, ensuring the cable maintains excellent transmission performance even after prolonged bending and twisting within the confined space of a robot. Kevlar thermoplastic elastomer, used as a star-twisted filler, not only ensures the stability of the star-twisted structure, providing stable signal transmission, but also serves as the cable's central tensile member, reducing the strain on the core wires. The tinned copper foil wire, composed of copper foil and polyester filament, offers superior tensile and torsional resistance compared to ordinary tinned copper. Its lower hardness compared to copper wire also prevents the braid from breaking and puncturing the core wires due to long-term operation, potentially affecting signal transmission. The PUR sheath exhibits excellent flexibility and elasticity, allowing the PUR-sheathed cable to bend easily within humanoid robots, preventing breakage or twisting. Furthermore, the PUR sheath's toughness and elasticity allow it to adapt to the tighter bend radius of the robot's confined space. This patented utility model addresses the problem of data transmission cables for dynamic applications in humanoid robots, ensuring stable signal transmission performance under the high load, high strength, and high durability of the robot. The utility model has been optimized and upgraded in terms of insulation materials, braiding materials, thermoplastic elastomers, shielding layers and outer sheaths. Compared with existing cables, it has shown higher softness, bending adaptability, fatigue resistance and safety in comprehensive performance, thereby better meeting the data transmission needs in dynamic applications of robots.

[0016] Figure 1 This is a schematic diagram of the cross-sectional structure of a data transmission cable for dynamic application of a humanoid robot body of the present utility model;

[0017] In the figure: 1. Tinned copper conductor, 2. FEP insulation material, 3. Kevlar fiber, 4. Thermoplastic elastomer, 5. Aluminum-plastic composite tape, 6. Tinned copper foil braid, 7. PUR outer sheath. DETAILED DESCRIPTION

[0018] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0019] The cross-sectional structure of the data transmission cable for dynamic application of humanoid robot body is as follows Figure 1As shown, it includes a signal transmission core wire, a filling strip, an aluminum-plastic composite tape 5, a tinned copper foil braided layer 6, and a PUR outer sheath 7. The signal transmission core wire is specifically made of Teflon FEP signal transmission core wire, and the filling strip is specifically made of thermoplastic elastomer 4 coated with Kevlar fiber 3. The four-core data transmission core wire, i.e., the signal transmission core wire, is star-twisted around the filling strip made of thermoplastic elastomer 4 coated with Kevlar fiber 3 as the center, wrapped with aluminum-plastic composite tape 5, wrapped with tinned copper foil braided layer 6, and wrapped with PUR outer sheath 7. More specifically, the filling strip is located in the center of the cable, and the four signal transmission core wires are arranged in a star-twisted cable around the filling strip as the center. The cable is then coated with aluminum-plastic composite tape 5, which is coated with tinned copper foil braided layer 6, which is coated with PUR outer sheath 7.

[0020] The signal transmission core cable primarily consists of a tinned copper conductor 1 and an FEP insulation material 2 wrapped around the tinned copper conductor 1. Specifically, the tinned copper conductor 1 is twisted through a back-twist process and then coated with FEP insulation 2 to form the signal transmission core cable. The use of FEP insulation 2 greatly reduces the impact of robot movement on the core cable, while the low dielectric constant of FEP also ensures stable signal cable transmission.

[0021] More specifically, the tinned copper conductor 1 utilizes IEC60228 class 6 0.08mm tinned copper wire. The use of 0.08mm ultra-fine tinned copper conductor 1 eliminates internal stress through a back-twisting process, ensuring conductor reliability under the long-term, high-intensity motion of humanoid robots. Furthermore, the tinned copper conductor 1 prevents oxidation of the FEP insulation 2 during extrusion at 220°C. The conductor utilizes IEC60228 class 6 0.08mm ultra-fine tinned copper wire for increased flexibility.

[0022] In specific implementations, the filling strip is mainly composed of Kevlar fiber 3 and thermoplastic elastomer 4 coated on the outside of the Kevlar fiber 3. The filling strip composed of high-strength tensile flame-retardant material Kevlar fiber 3 and thermoplastic elastomer 4 serves as the central support of the star-twisted structure. It can not only withstand the impact of bending or twisting on the line during robot movement, but also increase the stability of the four-core signal line, thereby ensuring the stability of the robot signal transmission. The use of Kevlar fiber braiding enhances the strength and wear resistance of the cable, significantly reducing the risk of fatigue damage caused by long-term bending and twisting. In addition, the introduction of thermoplastic elastomer not only reduces the friction when the cable is bent, but also improves the overall flexibility and bending adaptability of the cable.

[0023] In a specific embodiment, the tinned copper foil braid layer 6 is braided from tinned copper foil. As a shielding material, the tinned copper foil has superior tensile and torsional properties compared to ordinary tinned copper. Its lower hardness compared to copper wire also prevents the braid from breaking and piercing the core wire after long-term operation, potentially affecting signal transmission. This provides shielding stability against signal interference and possesses high mechanical strength to withstand large-angle bending and torsion, effectively improving the cable's anti-interference capabilities and ensuring the purity and stability of signal transmission. Furthermore, the aluminum-plastic composite tape 5 within the cable acts as both a shielding and structurally stable core wire, ensuring that the cable maintains good data transmission characteristics even after prolonged robot movement, providing stable and reliable data transmission for the robot.

[0024] In a specific implementation, the PUR outer sheath 7 is made of PUR.

[0025] Certain modifications and variations of the present invention should also fall within the scope of protection of the claims of the present invention. Furthermore, although certain specific terms are used in this specification, these terms are for convenience only and do not constitute any limitation on the present invention. As described in the above embodiments of the present invention, other wires and cables with the same or similar structures are also within the scope of protection of the present invention.
