[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example

[0024] like Figures 1-4 As shown, the utility model provides a technical solution: an automobile wiring harness with an anti-bending structure, comprising: an anti-bending mechanism 1, an auxiliary mechanism 2 is provided on the outside of the anti-bending mechanism 1, the anti-bending mechanism 1 comprises a wire core 11, a transverse plate 15 is provided on the outside of the wire core 11, a force-bearing plate 13 is provided on the top side of the transverse plate 15, the top side of the transverse plate 15 is fixedly connected to one end of the force-bearing plate 13, the other end of the force-bearing plate 13 is provided with an arc-shaped plate 12, the other end of the force-bearing plate 13 is fixedly connected to one end of the arc-shaped plate 12, the top side of the force-bearing plate 13 is provided with a wire harness outer skin 19, the top side of the force-bearing plate 13 is fixedly connected to the inner side of the wire harness outer skin 19, and one side of the transverse plate 15 A side plate 14 is provided, one side of the horizontal plate 15 is fixedly connected to one end of the side plate 14, a connecting ball 16 is provided on the top side of one end of the horizontal plate 15, and the top side of one end of the horizontal plate 15 is fixedly connected to one end of the bottom side of the connecting ball 16, an outer ring 17 is provided on the outside of the connecting ball 16, and the outer side of the connecting ball 16 is movably connected to the inner surface of the outer ring 17, an inner rod 18 is provided on one side of the outer ring 17, one side of the outer ring 17 is fixedly connected to one end of the inner rod 18, the outer side of the inner rod 18 is fixedly connected to the inner wall of the wiring harness outer skin 19, one end of the wiring harness outer skin 19 is fixedly connected to one side of the outer ring 17, and the inner side of the outer ring 17 is movably connected to the outer side of one end of the wire core 11.

[0025] In this embodiment, when the automotive wiring harness with an anti-bending structure is in use, four transverse plates 15 are equidistantly designed on the outside of the wire core 11, and each transverse plate 15 has the same components. First, the two ends of the arc plate 12 are connected to one end of the force-bearing plate 13, and the top side of the force-bearing plate 13 is fixed to the inner side of the wire harness outer skin 19. In this way, when the wire core 11 is subjected to external force, the pressure is first received by the force-bearing plate 13, and then the arc plate 12 is deformed. The arc plate 12 absorbs and disperses the impact force through deformation. If the external force is too large, the degree of bending of the wire core 11 can be reduced under the action of the transverse plate 15, and the bending part is obtained. The outer ring 17 is installed on the outside of the core 11, and the outer ring 17 can rotate slightly when the twisting occurs. The outer ring 17 is the same as the harness sheath 19, and the internal structure strength is increased by the inner rod 18. Therefore, the stress on the core 11 during the twisting process can be effectively reduced, and the line breakage caused by twisting can be avoided. This design makes it difficult for the harness to cause damage to the internal core 11 when subjected to external force.

[0026] In addition, the connecting ball 16 designed between the outer ring 17 and the core 11 allows greater freedom of movement between the outer ring 17 and the core 11 when the outer ring 17 rotates slightly, so that the outer ring 17 will not directly apply additional stress to the core 11 when twisting and moving, thereby reducing potential damage. Example

[0027] like Figure 1-Figure 2 As shown, the auxiliary mechanism 2 includes a wear-resistant layer 21, an anti-corrosion layer 22 is provided on the inner side of the wear-resistant layer 21, the inner side of the wear-resistant layer 21 is fixedly connected to the outer side of the anti-corrosion layer 22, and the inner side of the anti-corrosion layer 22 is fixedly connected to the outer side of the wiring harness outer skin 19.

[0028] In this embodiment, a wear-resistant layer 21 and an anti-corrosion layer 22 are respectively installed on the outer skin of the wiring harness 19, and the anti-corrosion layer 22 is designed on the inner side of the wear-resistant layer 21. The wear-resistant layer 21 is made of polyurethane material, and the anti-corrosion layer 22 is made of polytetrafluoroethylene material. The polyurethane material has excellent wear resistance and can effectively protect the wiring harness from mechanical wear, especially in high friction environments. Polytetrafluoroethylene is used as the material of the anti-corrosion layer 22, which has excellent chemical stability and corrosion resistance. It can resist the erosion of various chemical substances, such as oils, solvents and other corrosive liquids, thereby ensuring the safety and reliability of the wiring harness under harsh working conditions. Therefore, the combination of the wear-resistant layer 21 and the anti-corrosion layer 22 provides a dual protection mechanism. When external wear occurs, the wear-resistant layer 21 is impacted first, and the anti-corrosion layer 22 continues to protect the internal wiring harness from chemical corrosion after the wear-resistant layer 21 is damaged.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
