Description

Technical Field

[0001] This utility model relates to the field of vehicle lighting technology, specifically to a combination taillight with dynamic lighting effect. Background Technology

[0002] As a professional automotive lighting manufacturer, our company has developed a series of different types of combination taillight products, such as CN220870682U, CN210373272U, and CN210454610U. Although these products are not exactly the same in appearance and function, they have all achieved good economic benefits in the market.

[0003] With technological advancements and evolving fashion trends, automotive lighting products are constantly being upgraded. On one hand, LED headlights are gradually replacing halogen headlights; on the other hand, there is a growing number of headlights with dynamic lighting effects. Therefore, designing a new taillight product that combines these two aspects with a simple structure and low cost is urgently needed. Research reveals that existing taillights of similar types (such as CN217356727U and CN216139911U), while integrating multiple headlight functions, still lack a sense of technology and style in terms of appearance and lighting effects. Utility Model Content

[0004] One of the objectives of this utility model is to provide a novel combined rear light product, which mainly includes a lens, an ADS-turn signal sub-assembly, a position light-brake light sub-assembly, and a lamp housing. The ADS-turn signal sub-assembly and the position light-brake light sub-assembly are directly or indirectly fixedly connected to the lamp housing, and the lens is sealed to the lamp housing.

[0005] In the above solution, both the ADS-turn signal sub-assembly and the position light-brake light sub-assembly include at least one LED module, and multiple LED beads are distributed on each LED module. The lighting method (mainly the lighting timing and lighting sequence) of the LED beads on each LED module is controlled by an LED driver device, thereby realizing a flowing animation lighting effect and the functions of vehicle lights such as position lights, brake lights, turn signals, and ADS marker lights.

[0006] In the above scheme, the ADS-turn signal sub-assembly includes an LED module d and a thick wall. The thick wall is fixedly connected to the LED module d, and the yellow-blue dual-core LED beads on the LED module d face the light-incident surface of the thick wall, while the light-emitting surface of the thick wall faces the light distribution lens. The yellow-blue dual-core LED can be controlled to emit yellow light or blue light, respectively realizing the functions of turn signal and ADS sign light. The lighting logic or priority is that the turn signal takes precedence over the ADS sign light, and the two have the same light emission form and number of LEDs.

[0007] In the above scheme, the LED module d is provided with 3-10 yellow-blue dual-core LED beads, preferably 8 (on one side). The yellow-blue dual-core LED beads are arranged horizontally along a straight line or along a curve from high to low or from low to high. These yellow-blue dual-core LED beads are lit sequentially from one end to the other (e.g., from left to right or from right to left), thereby forming a linear turn signal and ADS sign light sequential animation lighting effect.

[0008] In the above solution, the position light-brake light sub-assembly includes LED module a, LED module b, and LED module c, wherein LED module b is connected to LED module a and LED module c to form a C-shaped structure. Multiple red LED beads, preferably 3-6 beads, are disposed on the same side surface of LED module a, LED module b, and LED module c. These LED beads form a C-shaped light strip, and when they are lit sequentially or simultaneously, they can respectively realize the functions of position lights and brake lights, wherein the position lights have a C-shaped flowing animation lighting effect.

[0009] In the above scheme, the number of LED beads on LED module a and LED module c are equal or unequal, preferably unequal.

[0010] In the above scheme, LED modules a and c are arranged at a certain distance from each other, and the ADS-turn signal sub-assembly (i.e., LED module d) is located between LED modules a and c and aligned with the same side (e.g., the right side) of both.

[0011] In the above solution, the combined rear light also includes a decorative frame, a mounting bracket, and a wiring harness assembly. The ADS-turn signal sub-assembly and the position light-brake light sub-assembly are fixedly connected to the decorative frame and the mounting bracket, respectively, and the mounting bracket is fixedly connected to the lamp housing; one end of the wiring harness assembly is electrically connected to the ADS-turn signal sub-assembly and the position light-brake light sub-assembly, and the other end is electrically connected to the LED driver and the vehicle power supply.

[0012] Compared with existing similar products, the novel combined rear light provided by this utility model has the advantages of simple structure, easy assembly, rich functions, and high expandability. More importantly, the use of multiple spliced ​​LED light sources simultaneously achieves a unique shape and dynamic lighting effect, effectively improving the product's technological feel and recognizability, and is expected to generate good economic benefits after its market launch.

Detailed Implementation

[0018] To enable those skilled in the art to fully understand the technical solution and beneficial effects of this utility model, the following detailed description is provided in conjunction with specific embodiments and accompanying drawings. It should be emphasized that the embodiments listed below are merely preferred embodiments of this utility model and do not constitute a limitation thereof. Any simple improvements made based on these embodiments will fall within the protection scope of this utility model.

[0019] The multi-functional combination taillight provided by this utility model uses LED as the light source and realizes the functions of vehicle lights such as position lights, brake lights, turn lights, and ADS logo lights. Furthermore, the position lights, turn lights, and ADS logo lights have a flowing animation lighting effect, which greatly enhances the overall aesthetics and technological feel of the vehicle.

[0020] like Figure 1-4 As shown, the combined rear light mainly includes a bi-color lens 1, a bi-color decorative frame 2, a mounting bracket 3, a thick wall 4, a lamp housing 5, a position braking LED module a 6, a position braking LED module b 7, an ADS turn signal LED module 8, a wiring harness assembly 9, and a position braking LED module c 10. Each LED module has a varying number of LED beads, arranged in a specific manner, and their lighting timing and sequence are controlled by an LED driver. The wiring harness assembly 9 is assembled with the lamp housing 5 to form the lamp housing assembly, while the thick wall 4, the position braking LED modules a 6, b 7, 8, c 10, and the mounting bracket 3 are assembled together to form the mounting bracket assembly.

[0021] The assembly process of the entire rear light assembly includes pre-assembly of the lamp housing assembly, pre-assembly of the mounting bracket assembly, and final assembly, with the specific processes as follows: Pre-installation of lamp housing assembly: The wiring harness assembly 9 passes through the mounting holes on the lamp housing 5 and is fixed to the lamp housing 5, thus completing the pre-installation of the lamp housing assembly.

[0022] Pre-assembly of the fixed bracket assembly: The ADS steering LED module 8 is assembled with the thick wall 4 by hot riveting to form a thick-walled sub-assembly, ensuring that all LED beads on the ADS steering LED module 8 face the light-incident surface of the thick wall 4; then, the position braking LED module a 6, position braking LED module b 7, and position braking LED module c 10 are installed onto the fixed bracket 3 by screws, so that the LED module ac is arranged in a C-shape; then, the thick-walled sub-assembly is installed onto the fixed bracket 3 by screws, so that the ADS steering LED module 8 is surrounded by the C-shaped structure, thus completing the pre-assembly of the fixed bracket assembly.

[0023] Final Assembly: The mounting bracket assembly and the lamp housing assembly are assembled together using screws to form the lamp housing sub-assembly; then, the dual-color decorative frame 2 is snapped onto the lamp housing sub-assembly using its built-in clips. Next, the lamp housing 5 is flipped over and the sealing screws are tightened, thereby locking the dual-color decorative frame 2 to the mounting bracket 3; finally, the dual-color light distribution lens 1 and the lamp housing 5 are sealed and connected using low-temperature hot plate welding, completing the assembly of the entire lamp. The front of the assembled lamp is as shown below. Figure 4 As shown, the area includes a C-shaped position brake light illumination area 11 and an ADS turn signal illumination area 12. These two luminous areas are independent of each other and do not interfere with each other.

[0024] The combined rear light product provided by this utility model has the following two major highlights: Highlight 1: The turn signals and ADS marker lights share a single reflective thick-walled structure. This structure efficiently reflects and refracts the yellow or blue light emitted by the yellow-blue dual-core LED beads (total power approximately 4.4W), achieving the functions of turn signals and ADS marker lights. Furthermore, the unique optical design gives the turn signals and ADS marker lights a crystal-clear visual effect, making them highly aesthetically pleasing and easily recognizable. More importantly, under the control of the LED driver, the individual LED beads of the turn signals and ADS marker lights illuminate sequentially, achieving a flowing dynamic effect. This significantly enhances the warning and visual appeal when the vehicle is turning, improving driving safety and a sense of technology.

[0025] Highlight Two: The position lights / brake lights utilize a high-reflectivity white mounting bracket, reflecting the red light emitted by multiple red LED beads onto the emulsified red area of ​​the dual-color decorative frame, thus achieving the functions of position lights and brake lights. Aesthetically, thanks to the excellent light diffusion characteristics of the emulsified red material, the position lights and brake lights exhibit a uniform and vibrant red light effect. Under the control of the LED drive unit, not only can a flowing animation lighting effect for the position lights be displayed, but also welcoming and farewell animation effects such as breathing can be achieved, adding a dynamic rhythm to the vehicle at night and effectively enhancing the vehicle's nighttime visibility and brand image.
