[0002] Driving at night in dim light can obstruct visibility and affect driving safety. Car lights can provide illumination, helping drivers to observe their surroundings and thus improving driving safety.

[0003] Currently, automotive headlights are bonded to their housings using gaskets. This means that if the LED chip inside the headlight is damaged, the gasket must be removed before the housing can be disassembled to replace the chip. Since the gasket is highly adhesive, removing it takes a long time, making it inconvenient to disassemble the housing and replace the LED chip.

[0004] To address the aforementioned deficiencies, a car lamp cover housing disclosed in CN213272482U is described. This housing incorporates fixing and positioning components. By pulling a movable rod, a locking block is engaged in a fixing groove, securing the inner cover to the outer cover. This simplifies assembly and disassembly, reduces disassembly time, improves installation efficiency, and enhances practicality. A drainage channel is included, allowing rainwater to be guided into the channel through drainage holes and then drained through drainage holes, effectively preventing rainwater from entering the outer cover and avoiding water seepage that could affect the car lamp or shorten its lifespan. A sealing ring further prevents rainwater from seeping into the outer cover, further improving its waterproof performance. This invention features a simple structure, reasonable design, convenient disassembly, high practicality, and excellent waterproofing effect.

[0005] In actual use of the above-mentioned device, although the purpose of convenient disassembly and assembly of the outer shell is achieved by using the limiting blocks, there are multiple sets of the limiting blocks. As a result, the limiting blocks need to be operated sequentially during disassembly and assembly, which causes the limiting blocks to disengage from the positioning groove, thus affecting the convenience of disassembly and assembly.

[0006] Therefore, we proposed a car headlight with an easily removable cover that can effectively solve the above problems. Utility Model Content

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Example 1: A car headlight with an easily removable cover solves the problem that existing headlights have multiple sets of limit blocks, which require sequential operation of the limit blocks during disassembly and assembly, causing the limit blocks to disengage from the positioning groove and affecting the ease of disassembly and assembly. The connection between the slider 6 and the slide groove 7 improves the ease of disassembly and assembly. The following is disclosed:

[0034] The front end of the housing 1 is fitted with a lampshade 2; the outer end of the housing 1 is connected to a bracket 3 by bolts, and the rear end of the housing 1 is provided with a heat dissipation groove 4; the outer end of the lampshade 2 is slidably connected with a pin 5, and the rear end of the pin 5 extends into the interior of the housing 1 to form a sliding mechanism, and the rear end of the pin 5 is fixed with a slider 6, the outer end of the slider 6 extends into the interior of the slide groove 7 to form a locking mechanism, and the slide groove 7 is opened inside the housing 1.

[0035] refer to Figures 1 to 4 The housing 1 can be installed on the car using the bracket 3. The LED beads inside the housing 1 illuminate through the lamp cover 2. The heat dissipation groove 4 dissipates the heat generated by the housing 1, thus preventing the housing 1 from overheating due to prolonged use. If the LED beads inside the housing 1 are damaged, the pin 5 is rotated, causing the slider 6 to slide inside the groove 7. After the slider 6 slides to the position, the pin 5 stops rotating, and then the lamp cover 2 is pulled, causing the lamp cover 2 to move, which in turn moves the pin 5. This movement of the pin 5 causes the slider 6 to disengage from the groove 7, thus allowing the lamp cover 2 to be easily separated from the housing 1. The LED beads inside the housing 1 can then be replaced and maintained. By reversing the above operation, the slider 6 will engage with the groove 7, thus allowing for quick assembly and disassembly of the housing 1 and the lamp cover 2.

[0036] Example 2: A car headlight with an easily detachable cover solves the problem of insufficient stability in the connection between slider 6 and slide groove 7 in Example 1. The stability of the connection between slider 6 and slide groove 7 can be improved by the engagement between locking block 8 and locking groove 9. The following is disclosed:

[0037] The rear end of the slider 6 is provided with a slot 9, and a block 8 is slidably engaged inside the slot 9. The rear end of the block 8 is slidably connected inside the housing 1. The rear end of the block 8 is connected with a first spring 10, and the rear end of the first spring 10 is connected inside the housing 1 to form a limiting mechanism. There are two sets of sliding grooves 7, which are diagonally arranged. The front end of the sliding groove 7 is open inside the housing 1. The front end of the block 8 is inclined, and there are two sets of the block 8. The inclined surfaces of the front ends of the two sets of block 8 are opposite. The rear end of the block 8 is connected with a pull rope 11, and the rear end of the pull rope 11 is slidably connected inside the housing 1 through a roller 12. The roller 12 is connected inside the housing 1 through a bearing. The middle of the rear end of the pull rope 11 is attached to a top rod 13, and the front end of the top rod 13 extends into the housing 1 to form a sliding mechanism. The outer side of the front end of the top rod 13 is connected with a second spring 14, and the front end of the second spring 14 is connected inside the housing 1.

[0038] refer to Figures 4 to 6 When slider 6 slides, it presses against block 8, causing block 8 to slide inward into housing 1. The movement of block 8 compresses the first spring 10, thus compressing it. After slider 6 reaches its position and engages with groove 7, the force of the first spring 10 pushes block 8 into groove 9, securing it in place. This prevents pin 5 from sliding, improving the stability of pin 5. Furthermore, when disassembling lampshade 2, push rod 13 needs to be pressed down. The movement of the push rod 13 will compress the second spring 14, causing it to be under pressure. The movement of the push rod 13 will also push the pull rope 11 to move, which in turn will cause the pull rope 11 to move and drive the locking block 8 to slide into the housing 1 via the roller 12. This will cause the locking block 8 to disengage from the locking groove 9, allowing the pin 5 to rotate. This facilitates the disassembly of the lamp cover 2. The force of the second spring 14 can push the push rod 13 to reset, thus preventing the push rod 13 from squeezing the pull rope 11 and moving. This improves the stability of the locking block 8 and the locking groove 9.

[0039] Example 3: A car headlight with an easily removable cover solves the problem of insufficient sealing between the housing 1 and the lamp cover 2 in Example 1. The sealing performance of the connection between the housing 1 and the lamp cover 2 can be improved by using a sealing gasket 15. The following is disclosed:

[0040] The rear end of the lampshade 2 fits inside the sealing gasket 15 to form a sealing mechanism, and the sealing gasket 15 is fixed inside the front end of the housing 1, and the sealing gasket 15 is concave.

[0041] refer to Figure 3 and Figure 7When the lampshade 2 moves, it will detach from the seal 15. When the lampshade 2 is installed, it will be inserted into the inside of the housing 1, so that the lampshade 2 will fit between the seal 15 to form a sealing mechanism. Since the seal 15 and the lampshade 2 are connected in a concave-convex manner, the sealing performance of the gap between the housing 1 and the lampshade 2 can be improved, thereby preventing water stains from entering.

[0042] Working principle: When using this type of automotive light with an easily removable cover, first, refer to... Figures 1 to 4 The housing 1 can be installed on the car through the bracket 3. The lamp beads inside the housing 1 can achieve the purpose of illumination through the lamp cover 2. By rotating the pin 5, the pin 5 rotates and drives the slider 6 to slide inside the slide groove 7. After the slider 6 slides to the position, the lamp beads inside the housing 1 can be replaced and maintained. By reversing the above operation, the slider 6 will engage with the slide groove 7, so that the housing 1 and the lamp cover 2 can be quickly disassembled and assembled.

[0043] refer to Figures 4 to 6 When the slider 6 slides, it will press the locking block 8. After the slider 6 moves to the position and engages with the slide groove 7, the slider 6 can be fixed inside the slide groove 7, thereby preventing the pin 5 from sliding. When disassembling the lamp cover 2, it is necessary to press the top rod 13. The movement of the top rod 13 will push the pull rope 11 to move. Then, the pull rope 11 moves and drives the locking block 8 to slide into the housing 1 through the roller 12. The force of the second spring 14 can push the top rod 13 to reset, thus improving the stability of the engagement between the locking block 8 and the slot 9.

[0044] refer to Figure 3 and Figure 7 When the lampshade 2 moves, it will detach from the seal 15. When the lampshade 2 is installed, it will be inserted into the housing 1. Since the seal 15 and the lampshade 2 are connected in a concave-convex manner, the sealing performance of the gap between the housing 1 and the lampshade 2 can be improved.
