Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automobile parts, in particular to an automobile lamp rear cover which is convenient for heat dissipation installation. Background Art
[0002] With the continuous increase in the number of cars in my country, car lighting accessories have also been well developed. There are several types of car headlights on cars, including halogen lamps, xenon lamps and LED lamps. Among them, the structure of LED lamps is sturdy and not easily affected by vibration. The light output brightness will not drop significantly during use. However, it has become difficult to popularize LED lamps as car headlights. The lamp holder of traditional LED car headlights is connected to the rear cover without a gap. Long-term operation causes the lamp holder to overheat and accumulates between the lamp holder and the lamp cover, affecting the service life of the car lamp. In addition, the connection method between the lamp cover, the lamp holder and the car frame is too simple, which is very easy to cause shaking due to external force or prolonged use. Utility Model Content
[0003] The main purpose of the utility model is to provide a car lamp rear cover that is easy to install for heat dissipation. By arranging partition plates inside and outside the rear cover, a certain gap is provided between the lamp holder, the car frame and the rear cover, thereby enhancing air flow and facilitating heat dissipation; by arranging a mounting plate, a trapezoidal limit block and a U-shaped fixing splint, the rear cover is more tightly connected to the car frame and is not easy to shake.
[0004] In order to solve the above technical problems, the utility model discloses a car headlight rear cover that is easy to install for heat dissipation, including: a cover body, the cover body is provided with an inwardly recessed installation groove, the installation groove is provided with evenly spaced outwardly extending reinforcement plates, partition plates are provided between each reinforcement plate and on the outside of the bottom of the reinforcement plate, and the height of the partition plates is lower than the reinforcement plates; installation plates are arranged around the cover body, fixed ribs are provided around the installation plate, installation holes are provided on the installation plate, trapezoidal limit blocks are provided on both sides of the installation hole, U-shaped fixing splints are provided on both sides of the cover body, the top of the U-shaped fixing splint is provided with an outwardly extending reinforcement edge, and the outside of the U-shaped fixing splint is provided with triangular reinforcement ribs.
[0005] According to one embodiment of the present invention, the cover, the mounting groove, the reinforcing plate, the partition plate, the mounting plate and the U-shaped fixing clamp are integrally formed.
[0006] According to one embodiment of the present invention, the number of the trapezoidal limit blocks is 8 groups.
[0007] According to one embodiment of the present invention, the number of the triangular reinforcement ribs is 5 groups.
[0008] Compared with the existing technology, this application can achieve the following technical effects:
[0009] 1) By setting partitions inside and outside the rear cover, a certain gap is created between the lamp holder, the vehicle frame and the rear cover, which enhances air flow and facilitates heat dissipation. By setting mounting plates, trapezoidal limit blocks and U-shaped fixing splints, the connection between the rear cover and the vehicle frame is tighter and less likely to shake.
[0010] Of course, any product implementing the present utility model does not necessarily need to achieve all of the above technical effects at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The following will describe the implementation methods of the present application in detail with reference to the accompanying drawings and examples, so that the implementation process of how the present application applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.
[0017] Please refer to Figure 1 and Figure 2 , Figure 1 This is a front view of the high-strength automobile engine underguard according to an embodiment of the present application. Figure 2This is a rear view of a high-strength automotive engine underguard according to an embodiment of the present application. As shown, a rear cover for automotive headlights designed for easy heat dissipation installation comprises: a cover body 10 having an inwardly recessed mounting groove 11, within which are evenly spaced, outwardly extending reinforcement plates 20; partition plates 30 disposed between each pair of reinforcement plates 20 and on the outside of the bottom of each reinforcement plate 20, the partition plates 30 being lower than the reinforcement plates 20; mounting plates 40 disposed around the periphery of the cover body 10, each having fixed ribs 41 disposed around the periphery; mounting holes 42 disposed on the mounting plates 40, with trapezoidal stoppers 43 disposed on either side of the mounting holes 42; and U-shaped fixing clamps 50 disposed on either side of the cover body 10, each having an outwardly extending reinforcement edge 60 disposed on the top of the U-shaped fixing clamp 50, and triangular reinforcement ribs 70 disposed on the outer side of the U-shaped fixing clamp 50.
[0018] In the embodiment of the present invention, an inwardly recessed mounting groove 11 is provided on the cover 10 for mounting. Evenly spaced, outwardly extending reinforcement plates 20 are positioned within the mounting groove 11. Separation plates 30 are positioned between each pair of reinforcement plates 20 and on the outside of the bottom of each reinforcement plate 20. Separation plates 30 are positioned lower than the reinforcement plates 20. By providing separation plates 30 inside and outside the rear cover, a gap is created between the lamp holder and the vehicle frame and rear cover, enhancing air flow and facilitating heat dissipation.
[0019] Furthermore, mounting plates 40 are provided around the cover 10 for mounting. Mounting holes 42 are provided on the mounting plates 40, and eight sets of trapezoidal stoppers 43 are provided on either side of the mounting holes 42 to secure the cover 10 in place, ensuring a tight connection to the vehicle frame and preventing it from shaking. Fixed ribs 41 are provided around the mounting plates 40 to further secure the cover 10 in place.
[0020] Furthermore, U-shaped fixing splints 50 are provided on both sides of the cover body 10 to further strengthen the position of the fixed cover body 10, which is both simple and firm. A reinforcing edge 60 extending outward is provided on the top of the U-shaped fixing splint 50 to enhance its strength. Then, triangular reinforcing ribs 70 are provided on the outside of the U-shaped fixing splint 50. The number of triangular reinforcing ribs 70 is 5 groups, which greatly improves the overall strength of the U-shaped fixing splint 50 and makes it less prone to damage.
[0021] Furthermore, the cover body 10, the mounting groove 11, the reinforcing plate 20, the partition plate 30, the mounting plate 40 and the U-shaped fixing splint 50 are integrally formed. By providing the mounting plate 40, the trapezoidal limit block 43 and the U-shaped fixing splint 50, the rear cover is more tightly connected to the car frame and is not easy to shake.
[0022] The above description shows and describes several preferred embodiments of the present application. However, as mentioned above, it should be understood that the present application is not limited to the form disclosed herein and should not be construed as excluding other embodiments. Instead, the present application can be used in various other combinations, modifications, and environments and can be modified within the scope of the present application through the above teachings or the technology or knowledge in the relevant field.
