Description

Technical Field

[0001] This utility model belongs to the field of automotive lighting clip technology, specifically relating to an anti-detachment plastic clip for a small automotive lighting fixture. Background Technology

[0002] In automotive lighting systems, small lamps are widely used, such as turn signals, brake lights, side marker lights, and interior reading lights. However, existing lamp clip-on structures have significant limitations in practical use, specifically as follows: 1. Existing plastic clips are bulky and difficult to disassemble and assemble: Small lamps have limited installation space, and the existing clip structure is too bulky, which means that tools are needed to disassemble and repair the lamps, which is time-consuming and laborious, and is difficult to adapt to the convenient maintenance needs of small spaces. 2. Cost and maintenance drawbacks of metal clips: Currently, some automotive lights use metal clips. Although they have high mechanical strength, the material cost of metal clips is high, increasing the cost of automobile manufacturing. They are also difficult to maintain, requiring professional tools and operating skills for disassembly, resulting in low maintenance efficiency and increased maintenance costs. Furthermore, long-term use can lead to corrosion and rust, which can reduce the fixing performance. Therefore, we propose a plastic clip to prevent detachment of small automotive lights.

[0016] Please see Figures 1-6 The anti-detachment plastic clip for small automotive lights provided by this utility model includes: The buckle fixing part 1 is fastened into the buckle groove 3 on the headlight body 2. A first buckle engaging protrusion 9 is provided on the side of the buckle fixing part 1 away from the buckle elastic part 7. The buckle fixing part 1 is fastened into the buckle groove 3 on the headlight body 2 through the first buckle engaging protrusion 9. A semi-enclosed through groove 10 is provided on the buckle fixing part 1 corresponding to the outer side of the first buckle engaging protrusion 9, which is used to squeeze the first buckle engaging protrusion 9 and make the first buckle engaging protrusion 9 disengage from the buckle groove 3. The headlight body 2 is provided with a headlight engaging protrusion 6 that is positioned and engaged with the headlight groove 5 on the body sheet metal 4. The snap-fit ​​elastic part 7 is located on the side of the snap-fit ​​fixing part 1 away from the headlight snap-fit ​​protrusion 6. The snap-fit ​​elastic part 7 is elastically snapped into the elastic groove 8 on the body sheet metal 4. The snap-fit ​​elastic part 7 has an arc-shaped structure and a maximum elastic deformation of 5mm. The snap-fit ​​elastic part 7 is provided with a second snap-fit ​​protrusion 11 that matches the elastic groove 8 on the body sheet metal 4. The snap-fit ​​fixing part 1 and the snap-fit ​​elastic part 7 are made of PA66 engineering plastic to form an integrated plastic snap-fit, which has good weather resistance and corrosion resistance, and can adapt to the use of automobiles in various complex environments, while ensuring the service life of the snap-fit. The plastic snap-fit ​​has an overall n-shaped structure with dimensions of 30mm in length, 20mm in width, and 32mm in height. It is compact in size and easy to install in various narrow spaces inside or outside the headlight.

[0017] This utility model's anti-detachment plastic clip is useful when installing small automotive lights, such as... Figure 5As shown, press the buckle fixing part 1 downwards through the first buckle engagement protrusion 9 into the buckle slot 3 on the headlight body 2 until a "click" is heard. The anti-detachment plastic buckle is then installed on the headlight body 2 through the buckle fixing part 1. Then, align the headlight body 2 with the installation position of the body sheet metal 4, so that the headlight engagement protrusion 6 is positioned and engaged in the headlight slot 5 on the body sheet metal 4. Then, press one end of the headlight body 2 corresponding to the anti-detachment plastic buckle, so that the buckle elastic part 7 is elastically engaged into the elastic slot 8 on the body sheet metal 4, and is limited and engaged in the elastic slot 8 by the second buckle engagement protrusion 11. At this time, the buckle elastic part 7 will make a "click" sound. Then check the fit of the headlight body 2. The installation is complete. When removing the headlights, such as Figure 6 As shown, push the headlight body 2 toward the snap-fit ​​elastic part 7 to cause the snap-fit ​​elastic part 7 to be elastically compressed. At this time, the headlight snap-fit ​​protrusion 6 will disengage from the headlight snap-fit ​​groove 5, causing the headlight body 2 to detach from the body sheet metal 4. Then, remove the headlight body 2. Then, use a screwdriver to gently push the snap-fit ​​fixing part 1 to disengage the first snap-fit ​​protrusion 9 from the snap-fit ​​groove 3, thus completing the disassembly of the anti-detachment plastic snap-fit ​​and the headlight body 2. It has the following beneficial effects: 1. Compared to metal buckles, the plastic buckle of this utility model is made of PA66 engineering plastic, which significantly reduces material costs; 2. It allows maintenance personnel to quickly complete disassembly and replacement, significantly shortening maintenance time and reducing maintenance costs; 3. As an independent snap-fit ​​component, it is small in size and does not take up too much space in the vehicle body. It can be adapted to most small lights on the market (turn signals, brake lights, etc.) and has a wide range of applications. 4. The high strength of PA66 material can withstand external forces such as vibration and impact during normal use of the vehicle lights, ensuring stable connection of vehicle light components and eliminating the risk of detachment.

[0018] In summary, the method of using the anti-detachment plastic clip for the small car light provided in this embodiment is as follows: When installing the small car light, press the clip fixing part 1 downwards through the first clip engagement protrusion 9 into the clip slot 3 on the car light body 2 until a "click" is heard. The anti-detachment plastic clip is then installed on the car light body 2 through the clip fixing part 1. Then, align the car light body 2 with the installation position of the body sheet metal 4, so that the car light engagement protrusion 6 is positioned and engaged in the car light slot 5 on the body sheet metal 4. Then, press one end of the car light body 2 corresponding to the anti-detachment plastic clip, so that the clip elastic part 7 is elastically engaged into the elastic slot 8 on the body sheet metal 4, and is limited and engaged in the elastic slot 8 by the second clip engagement protrusion 11. At this time, the clip elastic part 7 will make a "click" sound. Then check the fit of the car light body 2. The installation is complete. When disassembling the headlight, push the headlight body 2 towards the elastic part 7 of the clip to compress the elastic part 7. At this time, the headlight latching boss 6 will disengage from the headlight slot 5, allowing the headlight body 2 to detach from the body sheet metal 4. Then, remove the headlight body 2. Next, use a screwdriver to gently push the clip fixing part 1 to disengage the first clip latching boss 9 from the clip slot 3, thus completing the disassembly of the anti-detachment plastic clip and the headlight body 2.
