Description

Technical Field

[0001] This utility model belongs to the field of automotive lighting technology, and more specifically, relates to an automotive lighting connection structure. Background Technology

[0002] In the automotive assembly system, headlights, as critical lighting components, require reliable sealing and protection to isolate them from external impurities such as moisture and dust, thus protecting the internal precision optical components. The adjusting nut, as a core component achieving this function, directly determines the assembly quality and long-term reliability of the headlight assembly. However, current technology, in order to balance sealing and adjustment, employs a process of heat-embedding the nut into the lamp body. This increases production steps and manufacturing costs, and also hinders assembly efficiency. Furthermore, the threaded engagement of the nut lacks sealing performance, creating a weakness where media can leak through the gaps in the threaded engagement, entering the lamp body and affecting headlight performance.

[0003] Existing technology includes a headlight mounting structure entitled "A Headlight Mounting Structure that is Easy to Assemble and Not Prone to Dislodgement," with publication number CN116788146A. This technology discloses a headlight mounting structure that is easy to assemble and not prone to dislodgement, comprising a headlight mounting angle on the headlight. The headlight mounting angle is a hollow structure, with an opening at the top for adjusting and fixing headlight mounting fasteners. The side of the hollow headlight mounting angle, corresponding to the opening of the opening, has a limiting structure to prevent the headlight mounting fasteners inside the opening from dislodging. This headlight mounting structure is reasonably designed; the adjusting bolt / nut is inserted into the opening through a spring clip, and limiting ribs on both sides of the opening provide restraint, while the spring clip prevents dislodging. There is no need to reduce the opening size, assembly and adjustment are simple, it is not prone to dislodging, and the structure is stable and reliable.

[0004] However, this technology does not address the technical issues and solutions of this application. Utility Model Content

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: This utility model is a car headlight connection structure. The upper part of the nut is provided with a threaded hole, the lower part of the nut is the closed end of the nut, the bottom of the threaded hole is a receiving cavity, the depth of the threaded hole is greater than the length of the bolt, the side of the nut is provided with a groove, the receiving cavity of the nut of the lamp body is provided with a rib, and the nut is engaged with the rib through the groove.

[0007] The ribs of the lamp body include an upper rib surface and a lower rib surface.

[0008] The nut includes an upper end face of the nut and an upper end face of the groove.

[0009] The aforementioned automotive headlight connection structure has sheet metal openings on its body sheet metal.

[0010] The upper end face of the nut is attached to the body sheet metal, and the bolt shank passes through the sheet metal opening and is screwed into the threaded hole of the nut. The cavity between the lower end face of the bolt shank and the bottom surface of the threaded hole is a receiving cavity.

[0011] The groove is a ring structure, and multiple ribs are arranged at intervals around the perimeter of the arrangement position. The ribs have a through hole in the middle, and the groove of the nut passes through the through hole.

[0018] The following description, with reference to the accompanying drawings, provides a more detailed explanation of the specific embodiments of this utility model, including the shape and structure of each component, the relative positions and connections between the parts, the functions and working principles of each part: As attached Figure 1 - Appendix Figure 3As shown, this utility model is a car headlight connection structure. The nut 2 has a threaded hole 202 at its upper part and a closed end 203 at its lower part. The bottom of the threaded hole 202 is a receiving cavity 205. The depth of the threaded hole 202 is greater than the length of the bolt 4. A groove 201 is provided on the side of the nut 2. A rib 103 is provided in the nut receiving cavity of the lamp body 1. The nut 2 is secured to the rib 103 via the groove 201. This structure addresses the shortcomings of existing technologies by proposing an improved technical solution. In this structural configuration, the components include a lamp body, a nut, body sheet metal, and bolts. The lamp body has a nut mounting position for accommodating the nut. The nut is installed at this nut mounting position. When the nut 2 and lamp body 1 are configured, a recessed groove 201 is provided on the side of the nut 2. The groove 201 has a ring-shaped structure. The nut receiving cavity of the lamp body 1 is provided with a rib 103. Multiple ribs 103 are arranged at intervals around the circumference of the nut 2, with a through hole 104 in the center. When the nut and lamp body are connected, the nut 2 is secured to the rib 103 via the groove 201, ensuring their positions are fixed. The nut 2 has a threaded hole 202 at its upper part, the depth of which is greater than the length of the bolt 4's thread. The bottom of the nut is a closed end. After the bolt 4 connects to the nut 2, the cavity between the lower end face 402 of the bolt and the bottom surface 208 of the threaded hole forms a receiving cavity 205. Even if moisture, dust, or other external impurities enter the threaded structure connecting the bolt 4 and nut 2 through the gap between the nut 2 and the bolt, they will only enter the receiving cavity 205 and will not pass through the nut 2 into the lamp body 1, thus solving the problem of impurity leakage and preventing lamp failure. The automotive lamp connection structure described in this utility model is simple in structure. While achieving a stable connection between the lamp and the body sheet metal, it integrates sealing and adjustment functions, solves the sealing problem at the thread, reduces structural complexity, saves costs, and improves the durability and safety performance of the lamp assembly.

[0019] The rib 103 of the lamp body 1 includes an upper rib surface 101 and a lower rib surface 102. The nut 2 includes an upper nut surface 204 and an upper groove surface 206. In the above structure, the rib 103 is used to mate with the groove, and the thickness of the upper rib surface 101 and the lower rib surface 102, as well as the height of the upper groove surface 206, are controlled so that after the rib and the groove are mated, they can only rotate and will not move axially, ensuring a stable connection.

[0020] The automotive headlight connection structure has a sheet metal opening 301 on the body sheet metal 3. The upper end face 204 of the nut fits against the body sheet metal 3, and the bolt 4 passes through the sheet metal opening 301 and is screwed into the threaded hole 202 of the nut 2. The cavity between the lower end face 402 of the bolt and the bottom face 208 of the threaded hole is a receiving cavity 205. In this structure, the sheet metal opening 301 is used for the bolt shank to pass through, the bolt end fits against the upper surface of the body sheet metal, and the nut fits against the lower surface of the body sheet metal.

[0021] The groove 201 is an annular structure, and multiple ribs 103 are arranged at intervals around the perimeter of the arrangement position. The center of the ribs 103 is a through hole 104, through which the groove 201 of the nut 2 passes. The body sheet metal 3 is placed on the upper end face 204 of the nut 2. After the bolt 4 passes through the sheet metal opening 301, the thread 401 of the bolt is threadedly connected to the threaded hole 202 of the nut 2, so as to achieve a stable assembly of the headlight and the body.

[0022] The lamp body 1 has a raised portion 105 on its upper rib surface 101. The raised portion 105 has a ring-shaped structure around the upper surface of the lamp body, and the inner diameter of the raised portion 105 is larger than the diameter of the nut 2. In this structure, the raised portion is used to prevent most external impurities such as moisture and dust from entering between the body sheet metal and the upper surface of the nut. Even if a small amount of impurities enters, they will be collected by the receiving cavity 205.

[0023] The height of the protrusion 105 is less than the thickness of the upper end face 204 of the nut and the upper end face 206 of the groove. The upper end face 204 of the nut and the upper end face 206 of the groove are arranged in parallel, and the upper end face 206 of the groove and the lower end face 207 of the groove are arranged in parallel. The lamp body 1 and the protrusion 105 are an integral structure.
