[0037] Some embodiments of the present application disclose a fixing member for fixing a vehicle body on a stud 3 of a lamp housing.

[0038] The fixing member comprises a sleeve 1 and a nut 2.

[0039] Specifically, the sleeve 1 can be sleeved on the stud 3, and the sleeve 1 is fixedly connected to the stud 3 to prevent the sleeve 1 from moving along the axial direction of the stud 3;

[0040] The sleeve 1 is provided with a baffle 11 and an external thread 12. The external thread 12 is provided at one end of the sleeve 1, and the end is located at the side of the baffle 11 that is used to abut against the vehicle body. The nut 2 is connected to the sleeve 1 through the external thread 12, and the nut 2 is used to press the vehicle body onto the baffle 11.

[0041] The process of fixing the vehicle body to the stud 3 of the lamp housing through the fixing parts is as follows:

[0042] First, the sleeve 1 is sleeved on the stud 3, and the sleeve 1 and the stud 3 are connected;

[0043] Then, the vehicle body is sleeved on the sleeve 1 until the vehicle body abuts against the baffle 11;

[0044] Finally, the nut 2 is matched with the external thread 12 of the sleeve 1 , and the nut 2 is rotated to press the vehicle body onto the baffle 11 .

[0045] The fixing part disclosed in the present application realizes the fixation of the vehicle body on the stud 3 of the lamp housing by cooperating with a sleeve 1 having a baffle 11 and an external thread 12 and a nut 2. Compared with the method in the prior art of connecting the vehicle body and the stud 3 of the lamp housing by self-tapping a thread 13 hole on the stud 3 with a screw, the stud 3 will not be damaged, and the method of cooperating with the nut 2 and the external thread 12 can meet the requirements of multiple disassembly.

[0046] The sleeve 1 is sleeved on the stud 3 of the lamp housing, and the sleeve 1 only occupies the outer circumference of the stud 3, and the occupied space is small, which is suitable for working conditions where the connection space between the vehicle body and the lamp housing is narrow, especially for use in some narrow spaces such as through-lights.

[0047] like Figure 1 As shown, the length of the sleeve 1 is shorter than the length of the stud 3. After the sleeve 1 and the stud 3 are sleeved and connected, the first end of the sleeve 1 in the axial direction abuts against the end of the stud 3 close to the lamp housing, and the second end of the sleeve 1 in the axial direction does not exceed the end of the stud 3 away from the lamp housing, and the stud 3 is partially exposed outside the sleeve 1.

[0048] The sleeve 1 and the stud 3 form a whole, and the baffle 11 is arranged in the middle of the sleeve 1 in the axial direction. The position of the baffle 11 is designed according to the distance between the lamp housing and the vehicle body to achieve effective support for the vehicle body.

[0049] In this solution, a self-tapping thread 13 is provided in the sleeve 1, and the sleeve 1 is connected to the stud 3 through the self-tapping thread 13. Specifically, the sleeve 1 is tapped on the stud 3 of the lamp housing through the self-tapping thread 13 with the assistance of an effective tool, and the sleeve 1 is threadedly connected with the stud 3 during the tapping process, so that the sleeve 1 is limited in the circumferential direction and the axial direction on the stud 3. It should be noted here that the self-tapping thread 13 in the sleeve 1 is opposite to the external thread 12 of the sleeve 1, so that the nut 2 further locks the sleeve 1 and the stud 3 during the process of tightening the sleeve 1.

[0050] Preferably, the sleeve 1 is a metal sleeve, which not only ensures the strength of the fixing piece, but also has good wear resistance and can be used repeatedly.

[0051] The connection between the sleeve 1 and the stud 3 is not limited to threaded connection, and may also be interference fit between the sleeve 1 and the stud 3 , or a clamping connection between the sleeve 1 and the stud 3 , or an adhesive connection between the sleeve 1 and the stud 3 .

[0052] When the sleeve 1 is connected to the stud 3 by snapping, a snap groove can be provided at the end of the stud 3 away from the lamp housing, and a snap protrusion cooperating with the snap groove is provided on the sleeve 1. The snap connection between the sleeve 1 and the stud 3 is achieved by the cooperation between the snap groove and the snap protrusion.

[0053] The sleeve 1 is not limited to a metal sleeve, but may also be a plastic sleeve.

[0054] The fixing member disclosed in the present application utilizes the original studs 3 on the lamp housing to achieve the connection between the lamp housing and the vehicle body, and does not need to improve the original lamp housing, so the cost is relatively reduced.

[0055] The baffle 11 and the sleeve 1 may be an integral structure or a separate structure.

[0056] In the embodiment where the baffle 11 and the sleeve 1 are an integral structure, the baffle 11 and the sleeve 1 are integrally formed.

[0057] In the embodiment where the baffle 11 and the sleeve 1 are separate structures, the baffle 11 and the sleeve can be connected by welding, threading, or clamping.

[0058] The cross section of the baffle 11 along the direction perpendicular to the axis of the sleeve 1 is hexagonal. In the embodiment where the baffle 11 and the sleeve 1 are integrally formed, an effective tool acts on the baffle 11 to apply a tightening force to the sleeve 1, reducing the difficulty of tapping the sleeve 1 on the stud 3.

[0059] In some embodiments of the present application, the nut 2 is a locking nut, which further improves the stability of the connection between the vehicle body and the lamp housing.

[0060] The nut 2 is not limited to a locking nut, and may be other forms of nuts 2, which are not specifically limited here.

[0061] The present application also discloses a lamp housing, including a lamp housing body, on which a stud 3 is arranged, and a fixing piece, which is a fixing piece recorded in any one of the above solutions.

[0062] Since the fixing member has the above technical effects, the lamp housing having the fixing member also has the same technical effects, which will not be described in detail herein.

[0063] The stud 3 can be a solid column or a hollow column, so as to ensure the connection strength between the vehicle body and the lamp housing.

[0064] The diameter and height of the stud 3 are designed according to the actual distance between the vehicle body and the lamp housing.

[0065] The present application also discloses a through-light, which is a decorative light that runs through the front or rear of a vehicle, forming a through-light shape with a very strong integrity at the front or rear of the vehicle.

[0066] The through-lamp disclosed in the present application includes a lamp housing, which is the lamp housing recorded in any one of the above schemes. Since the lamp housing has the above technical effects, the through-lamp having the lamp housing also has the same technical effects, which will not be repeated here.

[0067] The above description is only a preferred embodiment of the present application and an explanation of the technical principles used, and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. The scope of application involved in the present application is not limited to the technical solution formed by a specific combination of the above-mentioned technical features, but should also cover other technical solutions formed by any combination of the above-mentioned technical features or their equivalent features without departing from the above-mentioned application concept. For example, the above-mentioned features are replaced with the technical features with similar functions disclosed in this application (but not limited to) to form a technical solution.
