Description

Technical Field

[0001] This utility model relates to the field of automotive lamp cover technology, and in particular to a waterproof fog-proof LED front and rear combined sealed lamp cover. Background Technology

[0002] Automotive headlight covers are transparent or semi-transparent protective components installed on the outside of vehicle headlights. They are usually made of polymer materials such as polycarbonate (PC) or acrylic (PMMA). Their core functions include optical control, physical protection, and aesthetic enhancement, making them a key component of vehicle lighting systems.

[0003] Most existing automotive headlight covers use adhesive sealing, which is a traditional "one-time rigid seal." Once a problem occurs, disassembly and resealing are difficult and costly, and parts are easily damaged during disassembly. After disassembly, residual old adhesive must be thoroughly cleaned. If not cleaned thoroughly, the new adhesive will not be compatible with the old adhesive, creating a "secondary gap." In addition, some models have heating functions. Although the headlights can release water mist when heated, it may cause the adhesive seal to soften, leading to detachment and failure. This needs to be improved. Utility Model Content

[0004] The purpose of this invention is to solve the problems of high difficulty and cost in disassembling and resealing the adhesive seal in the existing technology, and to propose a waterproof fog LED front and rear combined sealing lamp cover.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a waterproof fog-proof LED front and rear combined sealed lamp cover, comprising a vehicle lamp body, a lamp cover, and a connecting device. The lamp cover is slidably connected to the surface of the vehicle lamp body. The connecting device is disposed on the vehicle lamp body and includes a groove. The groove is formed on the vehicle lamp body and penetrates the lamp cover. A fixed shaft is fixedly connected to the inner wall of the groove. A limiting block is rotatably connected to the surface of the fixed shaft. The limiting block is slidably connected to the inner wall of the groove and abuts against the surface of the lamp cover.

[0006] Furthermore, a spring is fixedly connected to the inner wall of the groove, and a stop plate is fixedly connected to the end of the spring away from the groove.

[0007] Furthermore, the abutment plate is slidably connected to the inner wall of the groove, and the side of the abutment plate away from the spring abuts against the limiting hole.

[0008] Furthermore, a slot is provided on the inner sidewall of the groove, and a block is slidably connected to the inner wall of the slot, the block being fixedly connected to the surface of the abutment.

[0009] Furthermore, the lampshade is provided with a drainage device, which includes a drainage hole on the lampshade, and the inner wall of the drainage hole is provided with a mounting groove.

[0010] Furthermore, a fixing block is fixedly connected to the inner wall of the placement slot, a rotating shaft is rotatably connected to the inner wall of the fixing block, a connecting block is rotatably connected to the surface of the rotating shaft, and a triangular plate is fixedly connected to the connecting block.

[0011] Furthermore, there are multiple sets of triangular plates, which are evenly arranged in a circle. A limiting plate is placed on the upper surface of each triangular plate, and the limiting plate is fixedly connected to the fixing block.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, a connecting device is provided to facilitate disassembly and assembly. In specific use, the limiting hole is moved, and the limiting block rotates around the fixed axis. At the same time, the limiting block loses its restraint on the lamp cover. The limiting hole pushes the abutment plate and squeezes the spring. The spring contracts under force. When the limiting block aligns with the through groove on the lamp cover, the lamp cover is pulled to separate the lamp cover from the vehicle lamp body. By setting up a connecting device, a snap-fit ​​structure is used to replace the traditional glue sealing solution to achieve component connection. This not only greatly simplifies the disassembly and assembly process and improves the ease of operation, but also effectively avoids problems such as the glue softening due to heat when the inside of the lamp cover is heated, causing it to fall off or fail. This effectively improves the practicality of the equipment.

[0014] 2. In this utility model, by setting a drainage device, water inside the lamp cover can be easily discharged. In actual use, water inside the lamp cover accumulates at the triangular plate. Due to gravity, the triangular plate and connecting block rotate downward around the axis, and the water inside the lamp cover is discharged from the triangular plate. Under the action of the limiting plate, the triangular plate cannot rotate upward, and external humid air cannot enter the lamp cover from the triangular plate. By setting a drainage device, functional damage to the core components of the vehicle lamp caused by water immersion and corrosion is fundamentally avoided. While extending the service life of the components, the frequency of maintenance caused by component failure is greatly reduced, thereby reducing the long-term vehicle use cost for users and effectively improving the stability of the equipment.

[0023] Please see Figures 1-6 This utility model provides a technical solution: a waterproof fog LED front and rear combined sealed lamp cover, including a vehicle lamp body 1, a lamp cover 2 and a connecting device 3. The lamp cover 2 is slidably connected to the surface of the vehicle lamp body 1, and the connecting device 3 is disposed on the vehicle lamp body 1.

[0024] The specific setup and function of its connecting device 3 and drainage device 4 will be described in detail below.

[0025] In this embodiment: the connecting device 3 includes a groove 31, which is formed on the headlight body 1 and passes through the lamp cover 2. A fixed shaft 32 is fixedly connected to the inner wall of the groove 31. A limiting block 33 is rotatably connected to the surface of the fixed shaft 32. The limiting block 33 is slidably connected to the inner wall of the groove 31 and abuts against the surface of the lamp cover 2.

[0026] The effect achieved by the above components is as follows: the limiting block 33 fixes the headlight body 1 and the lamp cover 2 together, replacing the glue sealing solution to realize the component connection, and greatly simplifies the disassembly and assembly process.

[0027] Specifically, a spring 34 is fixedly connected to the inner wall of the groove 31, and a stop plate 35 is fixedly connected to the end of the spring 34 away from the groove 31.

[0028] Specifically, the abutment 35 is slidably connected to the inner wall of the groove 31, and the side of the abutment 35 away from the spring 34 abuts against the limiting hole.

[0029] The effect achieved by the above components is to provide support for the limiting block 33 by setting up the spring 34 and the abutment plate 35.

[0030] Specifically, a slot 37 is provided on the inner side wall of the groove 31, and a block 36 is slidably connected to the inner wall of the slot 37. The block 36 is fixedly connected to the surface of the abutment plate 35.

[0031] The effect achieved by the above components is as follows: the slot 37 and the block 36 are provided to support the abutment 35 and prevent the abutment 35 and the spring 34 from falling to the bottom of the groove 31.

[0032] Specifically, the lampshade 2 is provided with a drainage device 4, which includes a drainage hole 41. The drainage hole 41 is opened on the lampshade 2, and the inner side wall of the drainage hole 41 is provided with a mounting groove 42.

[0033] Specifically, a fixing block 43 is fixedly connected to the inner wall of the mounting slot 42, a rotating shaft 44 is rotatably connected to the inner wall of the fixing block 43, a connecting block 45 is rotatably connected to the surface of the rotating shaft 44, and a triangular plate 46 is fixedly connected to the connecting block 45.

[0034] The effect achieved by the above components is that the triangle plate 46 has a certain elasticity. When there is a lot of water inside, the water will fall out of the lampshade 2 due to gravity. After the water is drained, the triangle plate 46 will reset.

[0035] Specifically, there are multiple sets of triangles 46, which are evenly arranged in a circle. A limiting plate 47 is placed on the upper surface of the triangles 46, and the limiting plate 47 is fixedly connected to the fixing block 43.

[0036] The effect achieved by the above components is: the limiting plate 47 is set to prevent the triangular plate 46 from rotating upward, which would cause external humid air to drift into the lampshade 2 and damage the internal parts of the lampshade 2.

[0037] Working principle: The connecting device 3 facilitates disassembly and assembly. In actual use, the limiting hole is moved, and the limiting block 33 rotates around the fixed shaft 32. At the same time, the limiting block 33 loses its restraint on the lamp cover 2. The limiting hole pushes the abutment plate 35 and squeezes the spring 34. The spring 34 is compressed under force. When the limiting block 33 aligns with the through groove on the lamp cover 2, the lamp cover 2 is pulled to separate the lamp cover 2 from the vehicle lamp body 1. By setting the connecting device 3, a snap-fit ​​structure is used to replace the traditional glue sealing solution to achieve component connection. This not only greatly simplifies the disassembly and assembly process and improves the ease of operation, but also effectively avoids problems such as the glue softening due to heat when the inside of the lamp cover 2 is heated, which can cause it to fall off or fail. This effectively improves the practicality of the equipment.

[0038] By setting up a drainage device 4, water inside the lamp cover 2 can be easily drained. In actual use, water inside the lamp cover 2 accumulates at the triangular plate 46. Due to gravity, the triangular plate 46 and the connecting block 45 rotate downward around the pivot 44, and the water inside the lamp cover 2 is drained out from the triangular plate 46. Under the action of the limiting plate 47, the triangular plate 46 cannot rotate upward, and external humid air cannot enter the lamp cover 2 from the triangular plate 46. By setting up a drainage device 4, functional damage to the core components of the vehicle light caused by water immersion and corrosion is fundamentally avoided. While extending the service life of the components, the frequency of maintenance caused by component failure is greatly reduced, thereby reducing the long-term vehicle use cost for users and effectively improving the stability of the equipment.
