They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0017] In the description of this utility model, it should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0018] Below with reference to the embodiment and the attached Figures 1 to 3 , the technical solution of the utility model is further elaborated.

[0019] Example 1

[0020] A shock-absorbing automotive high-voltage wire harness comprises: a wire harness body 1 and a shock-absorbing assembly 2, wherein annular protrusions 12 are provided at intervals on the wire harness body 1, and annular grooves 11 are provided between the annular protrusions 12; the shock-absorbing assembly 2 comprises a shock-absorbing pad 21, an adhesive block 22 and a fixing clip 23; a notch 211 is provided at the upper end of the shock-absorbing pad 21, and a clamping cavity 212 extends inward from the notch 211 to clamp the wire harness body 1; the adhesive block 22 is fixed to the bottom of the shock-absorbing pad 21, and the fixing clip 23 is arranged at the bottom of the adhesive block 22.

[0021] like Figures 1 to 3 As shown, the working principle of the present invention is as follows: the notch 211 and the clamping cavity 212 of the shock-absorbing pad 21 are designed to be clamped into the annular groove 11 on the wiring harness body 1, so that the shock-absorbing pad 21 can be tightly fixed on the wiring harness body 1 to form a stable connection. The shock-absorbing pad 21 effectively absorbs the vibration generated during the driving of the car, reduces the damage to the high-voltage wiring harness by the vibration, and improves the durability and reliability of the wiring harness; at the same time, the bottom of the shock-absorbing pad 21 is bonded and fixed to the internal bracket of the car through the bonding block 22 to achieve a stable connection; if the fixed position is not convenient for bonding, it can be clamped and fixed by the fixing clip 23 bonded to the bottom of the bonding block 22. Different fixed connections are performed according to actual conditions to ensure the shock-absorbing performance of the wiring harness.

[0022] As a further preferred embodiment, a heightened shock-absorbing pad 24 is provided at the bottom of the bonding block 22, a second bonding block 25 is provided at the bottom of the heightened shock-absorbing pad 24, and the fixing clip 23 is disposed at the bottom of the second bonding block 25. The heightened shock-absorbing pad at the bottom of the bonding block increases the thickness of the shock-absorbing assembly, thereby improving the shock-absorbing effect. Depending on the actual interior conditions of the vehicle, the thickness of the shock-absorbing assembly can be increased to ensure a stable connection to the bracket at the bottom. The second bonding block at the bottom of the heightened shock-absorbing pad provides additional support for the fixing clip, making it more stable.

[0023] As a further preferred embodiment, circular arc guide grooves 213 are provided on both sides of the upper end of the notch 211. The circular arc guide grooves on both sides of the upper end of the notch enable the shock-absorbing pad to slide more smoothly along the annular protrusion of the wiring harness body, reducing friction during installation and facilitating installation and adjustment of the shock-absorbing pad.

[0024] As a further preferred embodiment, a rubber pad 231 is provided inside the fixing clamp 23. A soft buffer layer is formed between the fixing clamp and the wiring harness body to absorb the impact force generated by vibration.

[0025] As a further preferred embodiment, the pressing grooves 232 on both sides of the fixing clip 23 are located outside the shock absorbing pad 21. The pressing grooves on both sides of the fixing clip are located outside the shock absorbing pad. This design makes it easier to press the fixing clip during installation to fix or release the wiring harness.

[0026] The above describes in detail the preferred embodiments of the present invention. It should be understood that those skilled in the art can make numerous modifications and variations based on the concepts of the present invention without inventive effort. Therefore, any technical solutions that can be derived by those skilled in the art based on the concepts of the present invention through logical analysis, reasoning, or limited experimentation based on the existing technology should be within the scope of protection defined by the claims.
