Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a two-color injection molded luminous grille compatible with AGS. Background Technology

[0002] With the development of the automotive industry, the design of the front face of a car has increasingly become the focus of brand recognition and consumer aesthetic attention. Illuminated car grilles, especially those using LED technology, are gradually becoming a design trend for mid-to-high-end models due to their unique visual effects and sense of technology.

[0003] Traditional light-emitting grilles typically achieve their lighting effect by distributing LED beads inside and covering them with a transparent or semi-transparent lampshade on the outside. This structural design results in poor light uniformity, easily causing a "grainy" or "hot spot" effect, and lacking a sense of sophistication.

[0004] On the other hand, active air intake grille (AGS) technology has been widely adopted to reduce wind resistance and improve fuel economy. The AGS system regulates the airflow into the engine compartment by controlling the opening and closing of the louvers inside the grille. Therefore, traditional grille designs must reserve sufficient air intake channel area free from optical structural interference for the AGS mechanism. Currently, designs combining luminous grilles with AGS systems present spatial contradictions. The installation position of the luminous module in the luminous grille often interferes with the moving parts of the AGS system. Either the performance of the AGS is sacrificed by reducing the opening angle of the blades in the AGS system to accommodate the luminous function, or the area and shape of the luminous area are limited to accommodate the AGS, leading to compromises in product design. Simply placing the luminous area alongside the air intake area would disrupt the overall integrity and aesthetics of the grille design. Utility Model Content

[0005] The purpose of this invention is to provide a two-color injection molded luminous grid that is compatible with AGS, which highly integrates the luminous function with the AGS function, and has a simple, reliable, beautiful and easy-to-manufacture structure.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a dual-color injection molded luminous grid compatible with AGS, including a lamp housing and a lamp cover, wherein the lamp housing and the lamp cover overlap each other to form a receiving cavity, a PCB board is disposed in the receiving cavity, and an LED lamp is mounted on the PCB board, wherein a plurality of light-transmitting parts are integrally formed on the lamp cover for transmitting the light emitted by the LED lamp, and each of the light-transmitting parts is spaced apart and forms an air intake area for accommodating AGS.

[0007] By adopting the above technical solution, the installation positions of the luminous grille and AGS are relatively independent, but the luminous function and AGS function are highly integrated, which improves the space utilization rate, ensures the integrity and aesthetics of the luminous grille, and ensures the performance of AGS. Moreover, the structure is simple, reliable and easy to manufacture.

[0008] A further feature of this invention is that the lampshade is made using a two-color injection molding process, and the light-transmitting part is made of a transparent material.

[0009] By adopting the above technical solution, the sealing effect between the light-transmitting part and the lamp cover body is improved, effectively preventing moisture and dust from entering the cavity from the seam, protecting the PCB board and LED light, and improving the product's durability and reliability.

[0010] A further feature of this invention is that the lampshade includes an ABS injection-molded portion and a PC injection-molded portion, wherein the PC injection-molded portion forms the light-transmitting portion, the ABS injection-molded portion constitutes the lampshade body excluding the light-transmitting portion, and an electroplating layer is provided on the lampshade body.

[0011] By adopting the above technical solutions, a combination of high-quality metallic texture and precise light transmission can be achieved.

[0012] A further feature of this invention is that the lamp housing and the lamp shade constitute a grid structure, the grid structure includes multiple parallel grid strips, and the light-transmitting portion is disposed on the grid strips and distributed along the length direction of the grid strips.

[0013] By adopting the above technical solution, the luminous grille is highly integrated with AGS, resulting in a reasonable layout that effectively increases the product's space utilization and makes the product more compatible.

[0014] A further feature of this invention is that the light-transmitting portion includes an upper light-transmitting portion and a lower light-transmitting portion, and both the upper light-transmitting portion and the lower light-transmitting portion include an upper inclined section, a vertical section and a lower inclined section, wherein the inclination direction of the upper inclined section is opposite to that of the lower inclined section.

[0015] By adopting the above technical solution, the light emitted by the LED lamp is guided and refracted from multiple angles and directions by the light-transmitting part, which effectively increases the light output area and uniformity, avoids the appearance of local bright spots or dark areas, and makes the final light-emitting lines or light bands fuller, more uniform and three-dimensional, thus enhancing the visual aesthetics and premium feel of the product.

[0016] A further feature of this invention is that a light guide is provided inside the receiving cavity, one end of which corresponds to the position of the LED lamp, and the other end extends along the length direction of the light-transmitting part and corresponds to the position of the light-transmitting part.

[0017] By adopting the above technical solution, the light uniformity is good, giving it a high-end feel.

[0018] A further feature of this invention is that a support is provided inside the receiving cavity, and a storage slot for accommodating the light guide is provided on the support. The light guide is fixedly connected to the storage slot, and one end of the support away from the storage slot is fixedly connected to the PCB board.

[0019] By adopting the above technical solution, the fixing strength of each part is higher and the vibration resistance is better.

[0020] A further feature of this invention is that a potting groove is formed at the junction of the lamp housing and the lamp shade, and a sealant is provided on the potting groove.

[0021] By adopting the above technical solutions, the sealing and heat dissipation problems caused by the long-term exposure of LED lights and PCB boards to vibration, high temperature and humidity, and water vapor corrosion caused by the front of the engine compartment are avoided, thus ensuring the effectiveness of sealing, waterproofing and heat dissipation performance.

[0022] A further feature of this invention is that a through hole is provided on the lamp housing, and a breathing membrane is provided at the opening end of the through hole away from the receiving cavity.

[0023] By adopting the above technical solution, the temperature and humidity difference between the inner cavity of the light-emitting grid and the external space can be effectively adjusted, avoiding problems such as condensation in the inner cavity and cracking due to pressure difference between the inside and outside.

[0024] A further feature of this invention is that the grid structure includes a connecting portion connecting the grid bars, the PCB board includes a first PCB board disposed within the grid bars, and a second PCB board disposed within the connecting portion, wherein the first PCB board and the second PCB board are distributed in parallel.

[0025] By adopting the above technical solution, the centralized PCB board is distributed in a decentralized manner, which effectively increases the heat dissipation area, avoids the accumulation of heat in a single area, thereby significantly reducing the temperature inside the cavity, extending the service life of the entire light-emitting grid, and ensuring the stability of the light effect.

[0026] In summary, this utility model has the following beneficial effects: 1. The lampshade is integrally molded with several light-transmitting sections made of light-transmitting material. Each light-transmitting section is spaced apart and forms an air intake area to accommodate the AGS. This makes the installation positions of the light-emitting grille and the AGS relatively independent, but it also highly integrates the light-emitting function with the AGS function, improving space utilization. It ensures both the integrity and aesthetics of the light-emitting grille and the performance of the AGS. Moreover, the structure is simple, reliable and easy to manufacture.

[0027] 2. The lampshade consists of an ABS injection-molded part and a PC injection-molded part. The PC injection-molded part forms the light-transmitting part, while the ABS injection-molded part constitutes the main body of the lampshade excluding the light-transmitting part. The main body of the lampshade is equipped with an electroplated layer, which on the one hand improves the sealing effect between the light-transmitting part and the main body of the lampshade, effectively preventing moisture and dust from entering the cavity from the seams, protecting the PCB board and LED lights, and improving the durability and reliability of the product. On the other hand, it achieves a combination of high-quality metallic texture and precise light transmission.

[0028] 3. A light guide is installed inside the cavity. One end of the light guide corresponds to the position of the LED light, and the other end extends along the length of the light-transmitting part and corresponds to the position of the light-transmitting part. The light-emitting grid emits light through the LED light on the PCB board. The light is transmitted through the light guide and then the light-transmitting part realizes the display of the light-emitting effect. The light uniformity is good and has a high-end feel.

[0029] 4. The lamp housing has a through hole, and a breathing membrane is installed at the opening end of the through hole away from the housing cavity. This allows air to pass freely while effectively blocking the entry of liquid water and dust. When the air pressure inside the housing cavity decreases, outside air enters the housing cavity through the breathing membrane. When the air pressure inside the housing cavity increases, the air inside the housing cavity is discharged to the outside through the breathing membrane. This achieves the effect of balancing the internal and external pressure difference, effectively regulating the temperature and humidity difference between the inner cavity of the light-emitting grid and the external space, and avoiding problems such as condensation inside the cavity and cracking due to internal and external pressure difference.

[0037] A dual-color injection molded, AGS-compatible luminous grid, such as Figure 1-5 As shown, the device includes a lamp housing 1 and a lamp shade 2, which overlap each other to form a receiving cavity 3. A PCB board 31 is disposed inside the receiving cavity 3, and an LED light is mounted on the PCB board 31. The LED light is mounted on the PCB board 31 via a patch. Several light-transmitting parts 4 are integrally formed on the lamp shade 2. The light-transmitting parts 4 are made of light-transmitting material and are used to transmit the light emitted by the LED light. The light-transmitting parts 4 are spaced apart and form an air intake area 5 for accommodating the AGS. Through the above design, the installation positions of the light-emitting grille and the AGS are relatively independent, but the light-emitting function and the AGS function are highly integrated, which improves the space utilization rate. It ensures both the integrity and aesthetics of the light-emitting grille and the performance of the AGS. Moreover, the structure is simple, reliable and easy to manufacture.

[0038] Preferably, the lampshade 2 is manufactured using a two-color injection molding process. Two-color injection molding refers to injecting two different materials into the same mold, thereby achieving a molding process in which the injection-molded part is formed from two materials. This process is a conventional technical method and will not be described in detail here. The light-transmitting part 4 is made of a transparent material. Through the above design, the sealing effect between the light-transmitting part 4 and the lampshade body 6 is improved, effectively preventing moisture and dust from entering the cavity 3 from the seam, protecting the PCB board 31 and the LED light, and improving the product's durability and reliability.

[0039] Preferably, the lampshade 2 includes an ABS injection-molded part and a PC injection-molded part, wherein the PC injection-molded part forms the light-transmitting part 4, and the ABS injection-molded part constitutes the lampshade body 6 other than the light-transmitting part 4. The surface of the lampshade body 6 is electroplated to achieve a high-flat texture effect. Through the above design, a combination of high-flat metallic texture and precise light transmission is achieved.

[0040] As a preferred embodiment, the light-transmitting part 4 is made of anti-aging PC material, which achieves paint-free protection, avoids the use of UV paint protection, and effectively controls costs.

[0041] As a preferred embodiment, the PC material of the light-transmitting part 4 is designed to be milky white, which effectively avoids problems such as fogging and condensation in the interior of automotive exterior lights.

[0042] Preferably, the lamp housing 1 and the lamp shade 2 constitute a grille structure, which includes multiple parallel grille bars 71. The grille bars 71 are preferably vertically arranged. The light-transmitting part 4 is disposed on the grille bars 71 and distributed along the length direction of the grille bars 71. Through the above scheme, the light-emitting grille and AGS are highly integrated, the layout is reasonable, the space utilization of the product is effectively increased, and the product is more compatible.

[0043] Preferably, the light-transmitting part 4 includes an upper light-transmitting part 41 and a lower light-transmitting part 42. Both the upper light-transmitting part 41 and the lower light-transmitting part 42 include an upper inclined section 43, a vertical section 44, and a lower inclined section 45. The inclined directions of the upper inclined section 43 and the lower inclined section 45 are opposite. Through the above design, the light-transmitting part 4 guides and refracts the light emitted by the LED lamp from multiple angles and directions, effectively increasing the light emission area and uniformity, avoiding the appearance of local bright spots or dark areas, and making the final luminous lines or light bands more full, uniform, and three-dimensional, thus enhancing the visual aesthetics and premium feel of the product.

[0044] Preferably, a light guide 32 is also provided in the receiving cavity 3, preferably a rigid injection molded light guide 32. The rigid injection molded light guide 32 has consistent color and brightness in light transmission and higher brightness energy, which enhances the user's sensory experience. One end of the light guide 32 corresponds to the position of the LED lamp, and the other end extends along the length direction of the light-transmitting part 4 and corresponds to the position of the light-transmitting part 4. The light-emitting grid emits light through the LED lamp on the PCB board 31. The light is transmitted through the light guide 32 and then the light-transmitting part 4 realizes the display of the light-emitting effect. The light uniformity is good and has a high-end feel.

[0045] Preferably, the cavity 3 is further provided with a bracket 33, and the bracket 33 has a storage slot 331 for accommodating the light guide 32. The light guide 32 is fixedly connected to the storage slot 331, and the end of the bracket 33 away from the storage slot 331 is fixedly connected to the PCB board 31. The light guide 32, the bracket 33, and the PCB are fixed in pairs as small components by screws, and the components are then fixed to the lamp housing 1 by screws. Through the above structure, the fixing strength of each part is higher and the vibration resistance is better.

[0046] Preferably, a potting groove 8 is formed at the joint between the lamp housing 1 and the lamp cover 2. A sealant 81 is provided on the potting groove 8. The sealant 81 is preferably a high-temperature resistant and water-resistant adhesive, such as silicone sealant, to avoid sealing and heat dissipation problems caused by the LED lamp and PCB board 31 being exposed to the front of the engine compartment for a long time and subjected to harsh environments such as vibration, high temperature and humidity, and water vapor corrosion, thus ensuring the effectiveness of sealing, waterproofing and heat dissipation performance.

[0047] Preferably, the lamp housing 1 has a through hole 11, and a breathable membrane 111 is provided at the opening end of the through hole 11 away from the receiving cavity 3. The breathable membrane 111 is a thin film made of high molecular polymer, which is adhered to the end face of the through hole 11. The breathable membrane 111 allows air to pass freely while effectively blocking the entry of liquid water and dust. When the air pressure in the receiving cavity 3 decreases, outside air enters the receiving cavity 3 through the breathable membrane 111. When the air pressure in the receiving cavity 3 increases, the air in the receiving cavity 3 is discharged to the outside through the breathable membrane 111, thereby achieving the effect of balancing the internal and external pressure difference. The breathable membrane 111 can effectively regulate the temperature and humidity difference between the inner cavity of the light-emitting grid and the external space, avoiding problems such as condensation in the inner cavity and cracking due to internal and external pressure difference.

[0048] Preferably, the grille structure includes a connecting portion 72 connecting the grille bars 71. The PCB board 31 includes a first PCB board 311 disposed within the grille bars 71 and a second PCB board 312 disposed within the connecting portion 72. The first PCB board 311 and the second PCB board 312 are distributed in parallel. Distributing the concentrated PCB boards 31 effectively increases the heat dissipation area, avoids heat accumulation in a single area, thereby significantly reducing the temperature inside the housing cavity 3, extending the service life of the entire light-emitting grille, and ensuring the stability of the light effect. In addition, the second PCB board 312 is embedded in the connecting portion 72, and its rigidity acts as a reinforcing rib, enhancing the structural rigidity of the connecting portion 72 and preventing it from deforming due to vibration or external impact. At the same time, the parallel distribution design allows the fixing points of the two PCB boards 31 to correspond to each other, forming a more stable internal support frame and improving the stability of the entire grille structure.

[0049] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
