Description

Technical Field

[0001] This utility model relates to the field of automotive lighting technology, and in particular to a structure for automotive grille light strips. Background Technology

[0002] The car grille, located at the front of the vehicle and typically in front of the engine radiator, serves not only basic functions such as ventilation, heat dissipation, and protection of internal components, but is also a crucial part of the car's front-end design, playing a key role in the overall appearance and brand recognition. With the development of the automotive industry, the grille design has evolved from a single functional component into an important carrier integrating aesthetic design and a sense of technology.

[0003] To enhance a vehicle's visual impact, technological sophistication, and nighttime visibility, integrating lighting strips into the grille has become a common design trend. These strips are typically used for daytime running lights, position lights, or decorative ambient lighting. However, existing grille light strips still face several technical challenges in practical applications: First, the complex and ever-changing driving environment requires the strips to be exposed to harsh conditions such as rain, dust, and alternating high and low temperatures, necessitating extremely high sealing and waterproofing performance. Second, as an exterior component, the grille light strips must provide uniform and consistent illumination to avoid uneven "zebra effects" or glare, which could affect the visual safety of oncoming vehicles or pedestrians and also contribute to the overall premium feel of the vehicle. Third, the strip structure needs to facilitate secure and reliable installation and fixation to the grille itself.

[0004] Existing automotive grille light strip structures often fall short in terms of waterproof sealing, light efficiency uniformity control, structural robustness, and ease of installation, making it difficult to simultaneously achieve high performance, high reliability, and good visual appeal. Therefore, there is an urgent need for a new type of automotive grille light strip structure to address these issues. Utility Model Content

[0005] The purpose of this invention is to provide a light strip structure for automotive grilles to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A car grille light strip structure includes an upper encapsulation housing, a lower encapsulation housing, and a PCB light board. The upper and lower encapsulation housings are snapped together to form a light strip housing. The PCB light board is installed inside the light strip housing. One side of the lower encapsulation housing has multiple protruding cavities, and a convex mirror is installed on the bottom surface of each protruding cavity. One side of the PCB light board has multiple protrusions that can be snapped into the protruding cavities, and the protrusions correspond to the convex mirrors. The upper encapsulation housing includes a fixed base plate, a cover plate, and multiple light-blocking covers. The fixed base plate and the cover plate are connected together. The fixed base plate is used to connect with the car grille structure to provide support and fixation. The cover plate covers the upper port of the lower encapsulation housing, and the edge gap is connected by sealant. Multiple light-blocking covers are located on the side of the cover plate, correspondingly covering the protruding cavities, and have notches on one side of the bottom and perimeter.

[0007] Based on the above technical solutions, this utility model also provides the following optional technical solutions: In one alternative: multiple convex cavities are arranged at equal intervals and are circular or square in shape; the convex mirror is located at the center of the convex cavity and protrudes outward.

[0008] In one alternative: the lower encapsulation housing is further provided with a plurality of equally spaced internal screw cylinders, and the cover plate is provided with a plurality of mounting through holes. When the cover plate covers the lower encapsulation housing, the plurality of mounting through holes correspond one-to-one with the plurality of internal screw cylinders.

[0009] In one alternative: the upper and lower encapsulation housings are formed by injection molding, and the material is flexible silicone or polycarbonate.

[0010] By adopting the above technical solution, this utility model has the following beneficial effects: This invention utilizes upper and lower encapsulation shells to form a sealed light strip housing, with sealant applied to the connecting edges to effectively isolate it from external environmental corrosion such as rain and dust. This ensures the long-term stable operation of the internal PCB light board, improving product reliability and lifespan. By incorporating equally spaced convex cavities and convex mirrors in the lower encapsulation shell, in conjunction with corresponding protrusions on the PCB light board, light is focused by the convex mirrors and emitted in a regular pattern, forming a uniform and continuous light band. This effectively avoids the "zebra effect" of alternating light and dark areas and glare, enhancing visual comfort and overall aesthetics. This invention integrates the PCB light board, optical components (convex mirrors), and sealed housing into a compact structure, forming an independent and fully functional lighting module. This facilitates production and assembly, and also allows for layout and installation within the lighting grid. Attached Figure Description

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] The left, right, up, and down positions of the various components shown in the attached diagram are just one arrangement method; the specific positions should be set according to specific needs.

[0020] In one embodiment, such as Figure 1-3As shown, a car grille light strip structure includes an upper encapsulation housing 100, a lower encapsulation housing 200, and a PCB light board 300. The upper encapsulation housing 100 and the lower encapsulation housing 200 are snapped together to form a light strip housing. The PCB light board 300 is installed inside the light strip housing. One side of the lower encapsulation housing 200 has multiple protruding cavities 210, and a convex mirror 400 is installed on the bottom surface of each protruding cavity 210. One side of the PCB light board 300 has multiple protrusions 310 that can be snapped into the protruding cavities 210. The protrusions 310 and... The convex mirror 400 corresponds to the upper encapsulation housing 100, which includes a fixed base plate 110, a cover plate portion 120, and multiple light-blocking covers 130. The fixed base plate 110 and the cover plate portion 120 are connected together. The fixed base plate 110 is used to connect with the automotive grille structure to provide support and fixation. The cover plate portion 120 is used to cover the upper port of the lower encapsulation housing 200, and the edge gap is connected by sealant. Multiple light-blocking covers 130 are provided on the side of the cover plate portion 120 and correspondingly cover the outer convex cavity 210. A notch is left on one side of its bottom and circumference.

[0021] In this embodiment of the utility model, the PCB light board 300 is hidden inside the light strip housing formed by the upper encapsulation housing 100 and the lower encapsulation housing 200. The connection between the upper encapsulation housing 100 and the lower encapsulation housing 200 is sealed with sealant to ensure the airtightness of the light strip housing and effectively play a waterproof role. The light tube emitted by the PCB light board 300 is focused and emitted by the convex lens 400, which can form multi-segment light emission. The light-blocking cover 130 guides the light that can pass through the convex lens 400 to one of the directions downward and around. The outer surface of the fixing substrate 110 is fixed to the automotive grille structure by coating it with double-sided adhesive.

[0022] In one embodiment, such as Figure 1-3 As shown, multiple convex cavities 210 are arranged at equal intervals and are circular or square in shape; the convex mirror 400 is located at the center of the convex cavity 210 and protrudes outward; in this embodiment of the present invention, the light emitted by the protrusions 310 in the convex cavities 210 distributed at equal intervals forms a regular light band, avoiding the "zebra effect" of alternating light and dark or strong glare, and reducing visual fatigue.

[0023] In one embodiment, such as Figure 1-3As shown, the lower encapsulation housing 200 is further provided with a plurality of equally spaced inner screw cylinders 220. The cover plate 120 is provided with a plurality of mounting through holes 140. When the cover plate 120 covers the lower encapsulation housing 200, the plurality of mounting through holes 140 correspond one-to-one with the plurality of inner screw cylinders 220. In this embodiment of the present invention, screws can be screwed into the inner screw cylinders 220 through the mounting through holes 140. Therefore, the lower encapsulation housing 200 and the upper encapsulation housing 100 can be fastened together by the cooperation of multiple sets of screws and inner screw cylinders 220, thereby improving the connection firmness between the upper encapsulation housing 100 and the lower encapsulation housing 200.

[0024] The upper encapsulation housing 100 and the lower encapsulation housing 200 are formed by injection molding, and their materials are flexible silicone or polycarbonate. Flexible silicone or polycarbonate has the properties of high and low temperature resistance, which effectively improves the service life of the light strip.
