These terms are merely used to distinguish items of information of the same type from each other. For example, first information could also be referred to as second information, and similarly, second information could also be referred to as first information, without departing from the scope of the present invention. Depending on the context, the word "if" as used herein may be interpreted as "when" or "upon" or "in response to determining that".

[0023] In the description of the present invention, it should be understood that orientation or position relationships indicated by the terms "longitudinal", "transverse", "up", "down", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. are based on the orientation or position relationships shown in the drawings, and are merely intended to facilitate and simplify the description of the present invention, rather than indicating or implying that the apparatus or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the present invention.

[0024] Figs. 1 to 4 show a schematic drawing of a wire harness grommet 1 according to an embodiment of the present invention. As shown in Fig. 1, a wire harness grommet is provided, this wire harness 1 ring comprising: a main body part 10, a hole 11 for a wire harness 2 to pass through being formed on the main body part 10, and an inner tube 12 being formed on the main body part 10, the innertube 12 being configured to accommodate and guide the wire harness 2, and a mating part 20, the mating part 20 being fitted around an outer side of the main body part 10, and being configured for fixing the main body part 10; a protrusion 14 is formed on an outer wall of the inner tube 12, the protrusion 14 coordinating with the mating part 20, fixing the main body part 10. According to the wire harness grommet 1 of the present application, the wire harness 2 may pass through the hole 11 on the main body part 10 of the wire harness grommet 1, and the wire harness 2 may be tightly fitted in the wire harness grommet 1 , such that the wire harness grommet 1 may safely protect the wire harness.

[0025] Specifically, as shown in Fig. 4, an opening 21 is formed on an inner wall of the mating part 20, and is configured to allow the protrusion 14 on the outer wall of the inner tube 12 of the main body part 10 to pass through, to realize fitting between the main body part 10 and the mating part 20. The mating part 20 may be an individual component, and is fixed to a vehicle body or a lamp housing or other panel by a fixing device, or may also be formed integrally with a vehicle body or a lamp housing or other panel; the present application does not impose a specific restriction, as long as the mating part is able to cooperate with the main body part 10 of the wire harness grommet 1. The quantities of the protrusion 14 and the opening 21 may be chosen according to requirements.

[0026] As shown in Fig. 4, a platform 22 is formed on the inner wall of the mating part 20 in a height direction, and is used for receiving the protrusion 14 on the outer wall of the inner tube 12 of the main body part 10. After the main body part 10 is inserted into the mating part 20, the main body part 10 rotates, until the protrusion 14 on the outer wall of the inner tube 12 thereof reaches the platform 22, completing fitting between the main body part 10 and the mating part 20. The platform 22 contacts a lower surface of the protrusion 14, preventing the main body part 10 from disengaging from within the mating part 20. The lower surface of the protrusion 14 is preferably a flat surface. An upper surface of the protrusion 14 is preferably an inclined face, to facilitate guiding during fitting.

[0027] In a preferred example, an inclined surface 23 is formed on the inner wall of the mating part 20 in the height direction, and the inclined surface 23 extends from the opening 21 to the platform 22. The inclined surface 23, in other words a slope design, may easily guide the protrusion 14 from the position of the opening 21 on the inner wall of the mating part 20 to the platform 22.

[0028] In an example, as shown in Fig. 4, a step 24 is formed between the platform 22 and the inclined surface 23, and a height of the platform 22 is lower than the inclined surface 23 that is adjacent thereto. The step 24 may prevent the main body part 10 from rotating in the mating part 20, preventing the main body part 10 from deviating in position once fitted.

[0029] As shown in Figs. 1 - 3, a slot 13 is provided on the inner tube 12 for engaging and fixing the wire harness 2. The slot 13 may guide the wire harness 2, while engaging and fixing it, such that the wire harness grommet 1 may safely protect the wire harness 2.

[0030] As shown in Fig. 5, the wire harness grommet 1 further comprises a washer 30, which is arranged between the main body part 10 and the mating part 20. The washer 30 may strengthen a frictional force to a certain extent, preventing relative rotation between the main body part 10 and the mating part 20, while also being able to improve the sealing performance of the wire harness grommet. An interference fit is preferably used before between the washer 30 and the main body part 10 and the mating part 20.

[0031] In an example, as shown in Fig. 3, a rib 15 is formed on one side of the main body part 10 that is opposite the inner tube 12. The rib 15 may strengthen the main body part; moreover, during fitting, the main body part 10 can be rotated by means of the rib 15, thereby facilitating operation.

[0032] In an example, sealing glue may also be poured in the inner tube 12 of the main body part 10 according to requirements, to satisfy sealing requirements.

[0033] The wire harness grommet according to the present application has a compact structure, and, with small dimensions, may fix the wire harness, while also being able to prevent relative rotation between the main body part and the mating part of the wire harness grommet, which prevents unwanted disengagement and is reliably stable.

[0034] The wire harness grommet 1 according to an embodiment of the present application, as an example, may be used in any lighting device. The lighting and / or signalling device may comprise any type of vehicle illuminating lamp and / or signal lamp, for example, a headlamp, daytime running lamp, central high-mounted brake lamp, direction indicator lamp, position lamp, rear brake lamp, etc.

[0035] The present application also provides a vehicle, which comprises the wireharness grommet 1 described above.

[0036] Although the present application has been described with reference to the drawings, the embodiments disclosed in the drawings are intended to provide an exemplary illustration of preferred embodiments of the present application, and should not be construed as limiting the present application.

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