[0029] The following is in conjunction with the appendix Figure 1-7 The present invention provides a more detailed description of an embodiment of a protective automotive rear combination lamp.

[0030] A type of automotive rear combination light with protective functions, such as Figure 1 , 2 As shown, it includes a lamp housing 1, a lamp shade 2, and a light source 3. The lamp shade 2 covers the light source 3 and is connected to the lamp housing 1. The lamp housing 1 has an integrally formed brim structure 4 on the side facing the lamp shade 2. The brim structure 4 protrudes from the lamp shade 2, and several reinforcing ribs 5 are evenly distributed at the bottom of the brim structure 4.

[0031] Specifically, during installation, the lamp cover 2, lamp source 3, and lamp housing 1 are assembled together to form a complete lighting unit. The protective principle of this automotive rear combination lamp lies in the fact that the lamp housing 1 has a unique brim structure 4 integrally formed on the side facing the lamp cover 2. This brim structure 4 protrudes from the lamp cover 2 and is located on the top side of the lamp housing 1 and is perpendicular to the lamp housing 1. When the vehicle is transporting goods such as sand and gravel, if stones are splashed up, the brim structure 4 can, due to its protruding position, first block the stones, preventing them from directly hitting the lamp source 3, thereby avoiding damage to the lamp source 3. This greatly improves the safety of the lamp source 3, effectively reduces the occurrence of damage to the lamp source 3 due to stone impact, and lowers maintenance and replacement costs. Furthermore, several reinforcing ribs 5 are evenly distributed at the bottom of the brim structure 4. These reinforcing ribs 5 greatly enhance the structural strength of the brim structure 4 itself. When the brim structure 4 is hit by a stone, the reinforcing ribs 5 can disperse the impact force and prevent the brim structure 4 from deforming or being damaged by external force, thereby extending the overall service life of the rear combination lamp, reducing the inconvenience caused by frequent replacement due to damage to the lamp source 3, and ensuring that the rear combination lamp can continuously and stably perform the lighting and signal indication functions during the driving process, thus improving driving safety.

[0032] In this embodiment, as Figure 4 As shown, the lamp housing 1 is a rectangular hollow structure with an opening at one end, and multiple positioning posts 11 are provided inside the lamp housing 1. One end of the positioning post 11 is fixedly connected to the lamp housing 1, and the other end passes through the lamp source 3 and is connected to the lamp cover 2.

[0033] Specifically, during the assembly of the light source 3, mounting holes 311 are provided on the light source 3 at positions corresponding to the positioning posts 11. The light source 3 is fitted into the positioning posts 11 through these mounting holes 311, achieving precise positioning and installation inside the lamp housing 1. Subsequently, when the lamp cover 2 is installed, the other end of the positioning post 11 passes through the light source 3 and connects to the lamp cover 2, allowing the lamp cover 2 to accurately cover the light source 3.

[0034] It is worth noting that the purpose of the positioning post 11 is to ensure the accuracy and stability of the installation of the light source 3 and the lamp cover 2, avoiding problems such as poor lighting effect or loose parts caused by installation deviations. Secondly, it makes the assembly process of the rear combination lamp simpler and more efficient, reducing the debugging time during installation. Furthermore, the stable installation structure helps to improve the overall reliability of the rear combination lamp, enabling it to better resist the influence of external factors such as vibration and bumps during vehicle operation, thus extending the service life of the rear combination lamp.

[0035] In this embodiment, as Figure 6 , 7As shown, a wiring hole 12 is also provided on one side of the lamp housing 1, and a terminal block 13 is connected to the wiring hole 12. The terminal block 13 is fixedly connected to the lamp housing 1.

[0036] Specifically, when connecting the rear combination lamps to the circuit, the external wires are connected to terminal 13. Terminal 13 acts as a bridge, connecting the external power supply to the lamp source 3 circuit inside the lamp housing 1. Furthermore, the good conductivity of terminal 13 ensures stable current transmission, allowing the external power supply to flow smoothly into the lamp housing 1, providing power to the lamp source 3 and enabling it to illuminate normally. This design makes the circuit connection of the rear combination lamps clear and convenient, facilitating installation and improving efficiency. At the same time, the fixed connection of terminal 13 ensures the stability of the connection, preventing loosening or detachment even during vehicle operation, including vibrations and bumps. This guarantees the stability and continuity of the power supply to the rear combination lamps, ensuring their normal operation of lighting and signal indication functions, and providing reliable protection for driving safety.

[0037] It is worth noting that, such as Figure 3 As shown, when the light source 3 is working, it generates heat, which accumulates inside the lamp housing 1. To accelerate heat dissipation, multiple heat dissipation holes 6 are provided on the back of the lamp housing 1, and these holes 6 employ a grille structure. Because air convection occurs inside and outside the lamp housing 1, cool air from the outside enters the lamp housing 1 through the grille-shaped heat dissipation holes 6 and encounters the hot air heated by the light source 3. Hot air rises due to its higher temperature and lower density, while cool air sinks due to its lower temperature and higher density. Under this principle of natural convection, cool air continuously enters the lamp housing 1, mixes with the hot air, and is carried out of the lamp housing 1, discharged into the external environment through the heat dissipation holes 6. The grille structure design ensures smooth airflow into and out of the lamp housing 1 while also preventing dust and debris from entering the lamp housing 1, thus avoiding interference with the normal operation of the light source 3.

[0038] The heat dissipation vent 6, with its grille structure design, effectively reduces the internal temperature of the lamp housing 1, preventing the lamp source 3 from experiencing performance degradation and shortened lifespan due to prolonged exposure to high temperatures. This ensures the stability of the lamp source 3, enabling it to emit light continuously and reliably, providing clear and stable illumination and signal indication for the area behind the vehicle. Simultaneously, the heat dissipation vent 6 also reduces the risk of malfunctions caused by overheating, lowers maintenance costs, and improves the overall reliability and durability of the rear combination lamp.

[0039] In this embodiment, as Figure 3 As shown, a fastening bolt 7 is provided at the middle position of the heat dissipation hole 6 in the lamp housing 1, and a fastening nut 8 is threaded onto the fastening bolt 7.

[0040] Specifically, when the rear combination light needs to be installed in a predetermined position on the rear of the vehicle, the fastening bolt 7 can be inserted into the installation cavity, and then the fastening nut 8 can be tightened to secure it firmly, thus completing the installation. Using bolts for fixing provides a reliable connection between the lamp housing 1 and other components, ensuring that the components remain stable and will not easily loosen or fall off even under bumpy and vibrating conditions during vehicle operation, thus protecting the integrity of the overall structure of the rear combination light. Furthermore, it facilitates future maintenance and upgrades of the rear combination light. If it is necessary to replace or add related auxiliary components, it can be quickly disassembled and installed by tightening the fastening nut 8, improving maintenance efficiency, reducing maintenance costs, and enhancing the flexibility and adaptability of the rear combination light in actual use.

[0041] In this embodiment, as Figure 3 As shown, the lamp housing 1 has a buckle 14 on both sides near the top, and the buckle 14 and the lamp housing 1 are integrally formed; the lamp shade 2 has a fastening member 21 on both sides corresponding to the buckle 14 of the lamp housing 1, and the fastening member 21 is engaged with the buckle 14.

[0042] Specifically, when assembling the rear combination light, after the light source 3 is installed on the lamp housing 1, the lamp cover 2 is then placed over the light source 3. Clips 14 are installed on both sides of the lamp housing 1 near the top, with the integrally formed clips 14 extending naturally. Fasteners 21 are provided on both sides of the lamp cover 2 corresponding to the clips 14. When the lamp cover 2 is brought close to the lamp housing 1, the fasteners 21 snap into the clips 14, and with a soft "click," the lamp cover 2 and the lamp housing 1 are initially fastened together. This allows for quick installation and removal of the rear combination light, facilitating maintenance personnel to inspect or replace internal components such as the light source 3, significantly reducing maintenance time.

[0043] In this embodiment, as Figure 4 As shown, the light source 3 includes a fixed panel 31, a backlight panel 32, and an LED lighting source 33. The fixed panel 31 has mounting holes 311 at the positions corresponding to the positioning posts 11, and the mounting holes 311 cooperate with the positioning posts 11. The backlight panel 32 is close to one side of the fixed panel 31, and the backlight panel 32 is electrically connected to the LED lighting source 33. Multiple LED lighting sources 33 are provided, each LED lighting source 33 is composed of multiple light-emitting lamp beads, and the LED lighting sources 33 are arranged in a straight line on the fixed panel 31.

[0044] Specifically, in the internal structure of the automotive rear combination lamp, the light source 3, as the core light-emitting component, is composed of a fixed panel 31, a backlight panel 32, and LED lighting sources 33. When assembling the rear combination lamp, the pre-drilled mounting holes 311 on the fixed panel 31 are precisely aligned with the positioning posts 11 inside the lamp housing 1. The fixed panel 31 is then slowly inserted along the positioning posts 11, with the positioning posts 11 passing through the mounting holes 311, securing the fixed panel 31 firmly inside the lamp housing 1 like a mortise and tenon joint, ensuring its precise positioning. Simultaneously, the backlight panel 32 is connected to the power supply via wires and fixed to the bottom of the fixed panel 31, and is connected to the LED lighting sources 33. At this time, multiple LED lighting sources 33 arranged in a straight line on the fixed panel 31 are also in place. When current is transmitted to the LED lighting sources through the lines, the LED beads, based on the photoelectric effect of semiconductors, efficiently convert electrical energy into light energy, emitting bright light to provide clear illumination and signal indication for the area behind the vehicle.

[0045] The working principle of this utility model:

[0046] When the rear combination light is working, the external wire connects to the circuit of the light source 3 through the terminal 13 on the lamp housing 1. The current flows through the LED lighting source composed of multiple light-emitting beads, causing it to emit light. Then, the positioning post 11 inside the lamp housing 1 cooperates with the mounting hole 311 of the lamp source 3 fixing panel 31 to achieve precise installation. The lamp cover 2 is connected to the lamp housing 1 by the fastener 14 to form a whole. The grid-like heat dissipation holes 6 on the back of the lamp housing 1 promote air convection heat dissipation. The cap structure 4 and its reinforcing ribs 5 resist the impact of stones. The fastening bolt 7 in the middle of the heat dissipation hole 6 can fix the auxiliary components. All parts work together to ensure stable lighting and reliable operation of the rear combination light.

[0047] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
