[0024] Figures 1 to 4 A schematic diagram of a wire harness loop 1 according to an embodiment of this application is shown. Figure 1 As shown, a wire harness loop 1 is provided, comprising: a main body 10 with a hole 11 for a wire harness 2 to pass through, and an inner tube 12 configured to accommodate and guide the wire harness 2; a mating part 20 sleeved on the outside of the main body 10 and configured to fix the main body 10; and a protrusion 14 formed on the outer wall of the inner tube 12, which cooperates with the mating part 20 to provide fixation of the main body 10. According to the wire harness loop 1 of this application, the wire harness 2 can pass through the hole 11 on the main body 10 of the wire harness loop 1, and the wire harness 2 can be tightly fitted into the wire harness loop 1, so that the wire harness loop 1 can safely protect the wire harness.

[0025] Specifically, such as Figure 4 As shown, an opening 21 is formed on the inner wall of the mating part 20, which is configured to allow the protrusion 14 on the outer wall of the inner tube 12 of the main body 10 to pass through, so as to realize the assembly between the main body 10 and the mating part 20. The mating part 20 can be a separate component, fixed to a panel such as a car body or lamp housing by a fixing device, or it can be formed integrally with a panel such as a car body or lamp housing. This application does not make specific limitations, as long as it can mate with the main body 10 of the wire harness loop 1. The number of protrusions 14 and openings 21 can be selected as needed.

[0026] like Figure 4 As shown, the inner wall of the mating part 20 has a platform 22 formed in the height direction, which is used to receive the protrusion 14 on the outer wall of the inner tube 12 of the main body 10. After the main body 10 is inserted into the mating part 20, the main body 10 is rotated until the protrusion 14 on the outer wall of its inner tube 12 reaches the platform 22, completing the assembly between the main body 10 and the mating part 20. The platform 22 contacts the lower surface of the protrusion 14 to prevent the main body 10 from coming out of the mating part 20. The lower surface of the protrusion 14 is preferably flat. The upper surface of the protrusion 14 is preferably inclined to facilitate guidance during assembly.

[0027] In a preferred embodiment, the inner wall of the mating portion 20 is formed with an inclined surface 23 in the height direction, the inclined surface 23 extending from the opening 21 to the platform 22. The inclined surface 23, or slope design, can easily guide the protrusion 14 from the position of the opening 21 on the inner wall of the mating portion 20 to the platform 22.

[0028] In one example, such as Figure 4 As shown, a step 24 is formed between the platform 22 and the inclined surface 23, and the height of the platform 22 is lower than that of the adjacent inclined surface 23. The step 24 can prevent the main body 10 from rotating in the mating part 20 and prevent the main body 10 from coming off the assembled position.

[0029] like Figure 1-3 As shown, the inner tube 12 has a groove 13 for engaging and fixing the wire harness 2. The groove 13 can guide the wire harness 2 and engage and fix it, so that the wire harness loop 1 can safely protect the wire harness 2.

[0030] like Figure 5 As shown, the wire harness loop 1 also includes a washer 30, which is arranged between the main body 10 and the mating part 20. The washer 30 can enhance the friction to a certain extent, prevent relative rotation between the main body 10 and the mating part 20, and also improve the sealing performance of the wire harness loop. The washer 30 is preferably fitted with the main body 10 and the mating part 20 by an interference fit.

[0031] In one example, such as Figure 3 As shown, the main body 10 has a rib 15 formed on the side opposite to the inner tube 12. The rib 15 can enhance the strength of the main body, and at the same time, the main body 10 can be rotated during assembly, thereby facilitating operation.

[0032] In one example, sealant can also be injected into the inner tube 12 of the main body 10 as needed to meet sealing requirements.

[0033] The wire harness loop structure of this application is compact, which can fix the wire harness in a small size, while also preventing relative rotation between the main body and the mating part of the wire harness loop, avoiding undesirable dislodgement, and ensuring stability and reliability.

[0034] The wire harness loop 1 according to an embodiment of this application can be used in any lighting device as an example. The lighting and / or signaling device may include any type of vehicle lighting and / or signal lights, such as headlights, daytime running lights, center high-mounted brake lights, turn signals, position lights, taillights, etc.

[0035] This application also provides a vehicle that includes the aforementioned wire harness loop 1.

[0036] Although this application has been described in conjunction with the accompanying drawings, the embodiments disclosed in the drawings are intended to illustrate preferred embodiments of this application and should not be construed as a limitation thereof.

[0037] While some embodiments of the general concept of this application have been shown and described, those skilled in the art will understand that changes may be made to these embodiments without departing from the principles and spirit of the general concept of this application, the scope of which is defined by the claims and their equivalents.
