Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive lighting parts technology, and in particular to a headlight bumper bracket with an anti-detachment structure. Background Technology
[0002] In the field of automotive body accessories, the headlight bumper bracket is a key load-bearing component connecting the headlight assembly and the bumper, and its vibration resistance and detachment performance directly affect driving safety. Existing headlight bumper brackets mainly use pre-drilled threaded holes on the bracket body to bolt to the vehicle body mounting base, relying on the thread preload to prevent detachment. This method is reliable under static conditions, but under long-term vibration, the bolt connection surface will experience fretting wear, leading to a decrease in the coefficient of friction and thus reducing the preload, which may cause the bumper bracket to detach.
[0003] Therefore, to address the above problems, a headlight bumper bracket with an anti-detachment structure is proposed. When the bumper bracket is subjected to vibration, the vibration energy is transmitted to the snap-fit bracket, which will undergo elastic deformation to dissipate part of the vibration energy. The limiting plate will act as a block to further consume some of the vibration energy. The remaining vibration energy will be conducted and dissipated through the bracket body, thereby reducing the displacement of the headlight bumper bracket caused by vibration and preventing the bumper bracket from falling off. Utility Model Content
[0004] In order to overcome the problem that in the daily use of traditional car headlight bumper brackets, the friction coefficient of the bolt connection surface decreases due to fretting wear under long-term vibration environment, thereby reducing the preload and potentially causing the bumper bracket to fall off.

The headlight mounting plate is provided at the bottom of the bracket body, the bumper connecting plate is provided at the top of the bracket body, and the anti-detachment component is provided on one side of the bracket body. The anti-detachment component includes a limiting plate and a snap-fit bracket. The limiting plate is provided on one side of the bracket body, and the snap-fit bracket is provided on one side of the limiting plate.
[0006] Preferably, by setting a limiting plate and a snap-fit bracket on the side of the bracket body, wherein the limiting plate extends vertically and the snap-fit bracket extends horizontally, when the bumper bracket is affected by vibration, the vibration energy is transmitted to the snap-fit bracket, the snap-fit bracket will undergo elastic deformation to dissipate part of the vibration energy, the limiting plate will act as a block to continue to consume part of the vibration energy, and the remaining vibration energy will be conducted and dissipated through the bracket body, thereby reducing the displacement of the headlight bumper bracket caused by vibration and preventing the bumper bracket from falling off.
[0007] Preferably, the anti-detachment component also includes anti-slip teeth, with anti-slip teeth arranged in an array on the inner side of the snap-fit bracket.
[0008] Preferably, the anti-detachment component also includes a mounting groove and a rubber pad, with the mounting groove provided on the inner side of the limiting plate and a rubber pad provided on the inner side of the mounting groove.
[0009] Preferably, the side of the headlight mounting plate has headlight mounting holes, and there are two sets of headlight mounting holes with an elliptical structure.
[0010] Preferably, the bumper connecting plate has a connecting hole on its side, and multiple sets of flange blocks are arranged in a ring on the inner side of the connecting hole.
[0011] Preferably, the support body is made of aluminum alloy sheet, and the surface of the support body is provided with an anodized layer.
[0012] Preferably, there are two sets of anti-detachment components, which are respectively located on both sides of the bracket body.
[0013] The beneficial effects of this utility model are:
[0014] By setting a limiting plate and a snap-fit bracket on the side of the bracket body, where the limiting plate extends vertically and the snap-fit bracket extends horizontally, when the bumper bracket is affected by vibration, the vibration energy is transmitted to the snap-fit bracket, which will generate elastic deformation to dissipate part of the vibration energy. The limiting plate acts as a block and continues to consume part of the vibration energy. The remaining vibration energy is conducted and dissipated through the bracket body, thereby reducing the displacement of the bumper bracket caused by vibration and preventing the bumper bracket from falling off.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0021] Example 1
[0022] Please see Figure 1 and Figure 2 This utility model provides an embodiment: a headlight bumper bracket with an anti-detachment structure, including a bracket body 1, a headlight mounting plate 2, a bumper connecting plate 3, and an anti-detachment component. The headlight mounting plate 2 is provided below the bracket body 1, and the bumper connecting plate 3 is provided above the bracket body 1. An anti-detachment component is provided on one side of the bracket body 1. The anti-detachment component includes a limiting plate 101 and a snap-fit bracket 102. The limiting plate 101 is provided on one side of the bracket body 1, and the snap-fit bracket 102 is provided on one side of the limiting plate 101.
[0023] Please see Figure 3 and Figure 4 In this embodiment, the anti-detachment component also includes anti-slip teeth 103. The inner side of the snap-fit bracket 102 is provided with anti-slip teeth 103, and the anti-slip teeth 103 are distributed in an array. In use, the anti-slip teeth 103 increase the friction coefficient, overcoming the problem of anti-slip failure caused by the decrease in the friction coefficient of the metal contact surface in a humid environment. When contact pressure is applied, the tip of the anti-slip teeth 103 undergoes microscopic plastic deformation, forming a mechanical interlock and generating molecular adsorption force to improve the composite friction coefficient. The anti-detachment component also includes an installation groove 104 and a rubber pad 105. The inner side of the limiting plate 101 is provided with an installation groove 104, and the inner side of the installation groove 104 is provided with a rubber pad 105. In use, the rubber strip absorbs vibration energy by compressing and deforming under the influence of impact energy, and reduces the abnormal noise generated by hard contact between the limiting block and the bumper.
[0024] The side of the headlight mounting plate 2 has headlight mounting holes 201. There are two sets of headlight mounting holes 201. The headlight mounting holes 201 are elliptical in shape. When in use, the elliptical headlight mounting holes 201 are affected by vibration. The long axis of the elliptical headlight mounting holes 201 deforms to absorb displacement, while the short axis remains tight to form an adaptive adjustment, allowing for fine adjustment of the installation position. This solves the assembly difficulty problem caused by the accumulation of headlight installation position tolerances. The side of the bumper connecting plate 3 has connecting holes 301. Multiple sets of flange blocks 302 are arranged in a ring on the inner side of the connecting holes 301. When in use, the multiple sets of flange blocks 302 arranged in a ring prevent cracks from forming in the area around the connecting holes 301 under alternating loads. The bracket body 1 is made of aluminum alloy plate. The surface of the bracket body 1 has an anodized treatment layer. When in use, the aluminum alloy material and the anodized treatment layer improve the corrosion resistance of the bumper bracket. Two sets of anti-detachment components are provided, and the two sets of anti-detachment components are respectively provided on both sides of the bracket body 1.
[0025] Example 2
[0026] Optionally, in actual use, the headlight assembly is first connected to the bracket body through the elliptical mounting hole of the headlight mounting plate 2. The long axis of the elliptical hole allows for fine-tuning of the position during installation to compensate for accumulated tolerances, while the short axis maintains the fastening force. Then, the bumper is connected to the connecting hole 301 of the bumper connecting plate 3. The annular flange block 302 on the inner side of the connecting hole 301 disperses the alternating load stress and prevents cracks in the connecting hole 301 caused by long-term vibration. The anti-loosening components on both sides of the bracket body form a double anti-loosening structure through the limiting plate 101 and the snap-fit bracket 102: when the vehicle vibrates during driving, the snap-fit bracket 102 first undergoes elastic deformation due to its horizontal extension design, absorbing some of the vibration energy; the limiting plate 101 extends vertically to form a rigid block, further consuming the vibration displacement; the remaining energy is conducted to the vehicle body structure through the bracket body, forming a three-level energy dissipation mechanism, significantly reducing the amount of bracket displacement and preventing the risk of detachment.
[0027] Example 3
[0028] The optional snap-fit bracket 102 features an array of anti-slip teeth 103 with a pointed microstructure. Under contact pressure, the tips of the anti-slip teeth 103 undergo microscopic plastic deformation, forming a mechanical interlock with the surface of the mounting base. Simultaneously, the molecular adsorption force enhances the interfacial bonding strength, increasing the composite friction coefficient and effectively resisting the decrease in friction coefficient under humid conditions. The mounting groove 104 inside the limiting plate 101 is fitted with a rubber pad 105. When vibration causes the limiting plate 101 to contact the bumper, the rubber pad 105 absorbs the impact energy through compression deformation, preventing direct metal-to-metal collisions that could produce abnormal noises. The anti-detachment components adopt a symmetrical dual-group layout, respectively located on both sides of the bracket body, ensuring that vibration energy can be effectively dissipated when transmitted from both directions.
[0029] Through the above steps, by setting a limiting plate 101 and a snap-fit bracket 102 on the side of the bracket body 1, wherein the limiting plate 101 extends vertically and the snap-fit bracket 102 extends horizontally, when the bumper bracket is affected by vibration, the vibration energy is transmitted to the snap-fit bracket 102, and the snap-fit bracket 102 will generate elastic deformation to dissipate part of the vibration energy. The limiting plate 101 generates a blocking effect and continues to consume part of the vibration energy. The remaining vibration energy is conducted and dissipated by the bracket body 1, thereby reducing the displacement of the headlight bumper bracket caused by vibration and preventing the bumper bracket from falling off.
[0030] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
