Technical Field

[0001] This invention relates to the field of automotive front bumper lighting technology, specifically to a luminous grille, a design method, a front bumper assembly, and a vehicle. Background Technology

[0002] With the development of technology and the improvement of people's living standards, vehicles are being used more and more widely, and people's requirements for vehicle performance are also getting higher and higher. As part of the front-end device of a vehicle, the grille is one of the symbols of the vehicle brand, and it has functions such as air intake, heat dissipation, reducing air resistance, and appearance decoration.

[0003] Currently, more and more automotive lighting fixtures are employing artistic design methods to meet styling needs, special requirements for light emission, and demands for more artistic aesthetics. A new trend has emerged: how to realize artistic styling within traditional automotive lighting fixtures, maximizing the fulfillment of styling requirements and customer needs. This allows for a greater artistic styling effect, and the realization of artistic automotive appearance largely relies on the support of lighting technology.

[0004] In the prior art, such as a vehicle luminous grille with patent number CN215361210U, a panel is included. The inner surface of the panel has a pattern composed of styling units. When a light source is illuminated, the pattern appears on the outer surface of the panel. This vehicle luminous grille also includes a frame and mounting parts. The frame is fixed to the inner surface of the panel. The mounting parts are arranged on the frame in a number corresponding to the number of styling units, and each mounting part is equipped with a light source that emits light to the styling units. Due to the loading limitation of the mounting parts, each light source corresponds one-to-one with each styling unit. The vehicle luminous grille of this utility model, through the frame fixed to the inner surface of the panel and the mounting parts arranged on the frame, can install light sources, thereby making the styling patterns arranged on the inner surface of the panel visible. Compared with the existing method of assembling ambient light strips, it has a better sense of refinement and usage effect.

[0005] However, the luminous grille does not have an air intake, resulting in poor heat dissipation. When used on larger new energy vehicles, it is difficult to meet the requirements for air intake and heat dissipation, and there is a problem of achieving interactive lighting effects without ensuring air intake.

[0022] In one embodiment, adjusting the structural parameters of the light-emitting grating in the optical simulation model, as well as the distance between the grating assembly and the skin, to obtain the structural parameters and distance corresponding to the expected reflection and transmission effect includes: Adjust the angle between the light source emitting panel and the light-receiving plate, and the angle between the light-receiving plate and the horizontal plane, to obtain the angle between the light source emitting panel and the light-receiving plate and the angle between the light-receiving plate and the horizontal plane corresponding to the expected reflection effect.

[0023] In one embodiment, if the distance between the light source and the inner panel of the grille corresponding to the desired light transmission effect is greater than the maximum distance between the light source and the inner panel of the grille, the distance between the light source and the inner panel of the grille, as well as the distance between the elongated hole of the outer panel of the grille and the light-bearing plate, are readjusted.

[0024] Thirdly, embodiments of this application also provide a front bumper assembly, which includes: Skin; A grille assembly connected to the skin, the grille assembly having an air intake and a light-receiving portion located above the air intake; A light-emitting component is disposed between the grille assembly and the skin.

[0025] In one embodiment, the light-receiving part is formed by all the light-receiving structures, the light-receiving structure includes a light-receiving plate and two connecting plates respectively disposed on both sides of the light-receiving plate, a horizontally disposed shielding plate is provided on the lower side of the light-receiving plate, and an extension plate protruding inward toward the light-receiving plate is provided on the upper part of the skin, the extension plate is disposed horizontally, the extension plate is located above the shielding plate, and partially extends into the projection range of the shielding plate in the vertical direction.

[0026] Fourthly, embodiments of this application also provide a vehicle that includes the aforementioned luminous grille.

[0027] The beneficial effects of the technical solutions provided in this application include: In designing this luminous grille, the grille assembly is used to connect with the skin.

The light-receiving structure design improves the light efficiency, enhances the visual effect, and makes the lighting effect brighter and more uniform, thus improving the aesthetics and recognizability of the vehicle's front face.

Detailed Implementation

[0040] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0041] This application provides a light-emitting grille, a design method, a front bumper assembly, and a vehicle, which can solve the problem that the existing light-emitting grille does not have an air intake, has poor heat dissipation performance, and is difficult to meet the air intake and heat dissipation requirements when used on larger new energy vehicles, thus making it difficult to achieve interactive lighting effects while ensuring air intake requirements.

[0042] like Figure 1 , Figure 3 and Figure 4 As shown, in one aspect, this application provides a light-emitting grid, which includes: The grille assembly 1 is used to connect with the skin 3. The grille assembly 1 is provided with an air intake 11 and a light-receiving part 12 located above the air intake 11. The light-emitting component 2 is disposed between the grille component 1 and the skin 3. The light-emitting component 2 is connected to the grille component 1 and is located above the light-receiving part 12. The light emitted by the light-emitting component 2 is reflected by the light-receiving part 12 and then passes through the grille component 1.

[0043] In designing this luminous grille, grille assembly 1 is used to connect with skin 3. Grille assembly 1 has an air inlet 11 and a light-receiving part 12 located above the air inlet 11. The luminous component 2 is disposed between grille assembly 1 and skin 3, connected to grille assembly 1 and located above the light-receiving part 12. The light emitted by the luminous component 2 is reflected by the light-receiving part 12 and then passes through grille assembly 1. In designing this luminous grille, an optical simulation model of the luminous grille is established; the structural parameters of the luminous grille in the optical simulation model, as well as the distance between grille assembly 1 and skin 3, are adjusted to obtain the structural parameters and distance corresponding to the expected reflection and transmission effect; according to the structural parameters and distance, the luminous component 2 is installed on grille assembly 1. Because the grille assembly 1 has an air intake 11 and the light-emitting component 2 is located between the grille assembly 1 and the skin 3, the light emitted by the light-emitting component 2 is reflected by the light-receiving part 12 and then passes through the grille assembly 1. The light-receiving structure design allows the light emitted by the light-emitting component 2 to pass through the grille assembly 1 after being reflected by the light-receiving part 12, which improves the light efficiency, enhances the visual effect, makes the lighting effect brighter and more uniform, and improves the aesthetics and recognizability of the front of the vehicle. By setting the air intake 11 on the grille assembly 1, the air intake and heat dissipation needs of the front of the vehicle are met, and the lighting effect interaction function is realized. The air intake needs and lighting effect interaction are harmoniously unified, which solves the problem that the existing light-emitting grille does not have an air intake, has poor heat dissipation performance, and is difficult to meet the air intake and heat dissipation requirements when used in larger new energy vehicles, and there is a problem that it is difficult to achieve lighting effect interaction under the premise of ensuring air intake needs.

[0044] like Figure 1 , Figure 2 , Figure 7 and Figure 9 As shown, in some optional embodiments, the grille assembly 1 is provided with a plurality of spaced light-transmitting holes 13, the light-transmitting holes 13 are located above the air intake 11, and each light-transmitting hole 13 is provided with a light-bearing structure 14. The light-bearing surface of the light-bearing structure 14 is located below the light-emitting component 2, and the light-bearing surface forms a set angle with the light source orientation of the light-emitting component 2 in the vertical section. All the light-bearing structures 14 together form the light-bearing part 12.

[0045] In this embodiment, the grille assembly 1 has multiple spaced-apart light-transmitting holes 13 located above the air intake 11. Each light-transmitting hole 13 has a light-receiving structure 14, the light-receiving surface of which is located below the light-emitting component 2, and the light-receiving surface forms a set angle with the light source orientation of the light-emitting component 2 in its vertical section. All light-receiving structures 14 together form a light-receiving section 12. The multiple spaced-apart light-transmitting holes 13, together with the light-receiving structures 14, form a continuous light-receiving section 12. The set angle enables directional reflection of light, giving the lighting effect a three-dimensional and layered visual effect. All the light-receiving structures 14 work together to eliminate the fragmented feeling of single-point light transmission, enhance the overall aesthetics and brand recognition of the vehicle's front face, and meet the stringent requirements of high-end models for artistic lighting effects. The special layout of the light-transmitting hole 13 located above the air intake 11 does not affect the air intake function and ensures the light transmission effect of the light-bearing part 12. The design of the light-bearing surface of the light-bearing structure 14 located below the light-emitting component 2 avoids the obstruction of light in the air intake area. This solves the problem that the existing light-emitting grille does not have an air intake, has poor heat dissipation performance, and is difficult to meet the air intake heat dissipation requirements when used in larger new energy vehicles, thus making it difficult to achieve interactive lighting effects under the premise of ensuring air intake requirements.

[0046] In this example, the surface of the light-receiving surface has a rough texture to ensure diffuse reflection and achieve a soft light curtain effect.

[0047] like Figure 7 and Figure 9 As shown, in some optional embodiments, the light-receiving structure 14 includes a light-receiving plate 141 and two connecting plates 142 respectively disposed on both sides of the light-receiving plate 141. The light-receiving plate 141 is inclined, with its upper surface serving as the light-receiving surface. The lower end of the light-receiving plate 141 is connected to the lower side of the light-transmitting hole 13, and its upper end is located inside the grille assembly 1. The width of the light-receiving plate 141 is less than or equal to the width of the light-transmitting hole 13. Both connecting plates 142 are connected to the inner side of the grille assembly 1 and are located at the edge of the light-transmitting hole 13.

[0048] In this embodiment, the specific construction of the light-receiving structure 14 is described. The light-receiving structure 14 includes a light-receiving plate 141 and two connecting plates 142 respectively disposed on both sides of the light-receiving plate 141. The light-receiving plate 141 is inclined, with its upper surface serving as the light-receiving surface. The lower end of the light-receiving plate 141 is connected to the lower side of the light-transmitting hole 13, and the upper end is located inside the grille assembly 1. The width of the light-receiving plate 141 is less than or equal to the width of the light-transmitting hole 13. Both connecting plates 142 are connected to the inner side of the grille assembly 1 and are located at the edge of the light-transmitting hole 13. Both connecting plates 142 are connected to the inner side of the grille assembly 1 and located at the edge of the light-transmitting hole 13, forming a stable support frame. This effectively prevents the light-receiving plate 141 from shifting or deforming under vibration or temperature changes. At the same time, it simplifies the installation process, allowing the light-receiving structure 14 to be quickly and accurately fixed at the light-transmitting hole 13, significantly improving assembly efficiency and product reliability. The light-receiving plate 141 is tilted and its upper surface serves as the light-receiving surface. Its tilt angle can be precisely matched with the light source orientation of the light-emitting component 2, ensuring that the light achieves the best reflection path on the light-receiving plate 141.

[0049] like Figure 2 , Figure 3 , Figure 7 and Figure 9 As shown, in some optional embodiments, the arrangement shape of all the light-transmitting holes 13 matches the upper shape of the air intake 11.

[0050] In this embodiment, the arrangement of all the light-transmitting holes 13 matches the upper shape of the air intake 11. Because the arrangement of the light-transmitting holes 13 matches the upper shape of the air intake 11, light can maintain a consistent reflection path when passing through the light-transmitting holes 13, avoiding the problem of uneven light effect caused by irregular hole positions. Combined with the optimized design of the light-receiving structure 14, the lighting effect forms a continuous and uniform luminous effect above the air intake 11, enhancing the refinement and artistic expression of the lighting effect, and creating a smooth visual transition, avoiding the visual defect of a separation between the air intake structure and the light-transmitting structure in traditional designs. This matching not only ensures functional requirements but also enhances the overall aesthetics of the vehicle's front end, creating a harmonious and unified artistic expression between the lighting effect and the air intake structure, enhancing the vehicle's recognizability and premium feel.

[0051] like Figure 4 and Figure 5 As shown, in some optional embodiments, the light-emitting component 2 includes: Mounting shell 21 is connected to the inner side of grille assembly 1. Mounting shell 21 is located above light-receiving part 12, and the shape of the lower side of mounting shell 21 matches the shape of light-receiving part 12. The light source 22 is disposed inside the mounting housing 21 and is used to emit light that shines on the light-receiving part 12.

[0052] In this embodiment, the specific structure of the light-emitting component 2 is described. The light-emitting component 2 includes a mounting shell 21 and a light source 22. The mounting shell 21 is connected to the inner side of the grille assembly 1 and is located above the light-receiving part 12. The lower shape of the mounting shell 21 matches the shape of the light-receiving part 12. The light source 22 is disposed inside the mounting shell 21 and is used to emit light that illuminates the light-receiving part 12. The precise matching of the lower shape of the mounting shell 21 with the shape of the light-receiving part 12 ensures that the light emitted by the light source 22 can accurately illuminate the light-receiving part 12 and ensures that the light illumination angle at all the light-transmitting holes 13 is consistent, resulting in a high degree of consistency in the light effect of the entire light-receiving part 12. Furthermore, the design of connecting the mounting shell 21 to the inner side of the grille assembly 1 achieves a high degree of integration between the light-emitting component 2 and the grille assembly 1, reducing the number of parts, simplifying the assembly process, and reducing space occupation.

[0053] like Figure 5 As shown, in some optional embodiments, the mounting housing 21 includes a lamp housing 211 and a light-transmitting mask 212. The lamp housing 211 has a U-shaped cross-section, with the opening of the lamp housing 211 facing downwards. The light source 22 is disposed on the top of the lamp housing 211, and the light-transmitting mask 212 is detachably disposed at the opening of the lamp housing 211.

[0054] In this embodiment, the specific structure of the mounting housing 21 is described. The mounting housing 21 includes a lamp housing 211 and a light-transmitting mask 212. The lamp housing 211 has a U-shaped cross-section with its opening facing downwards. The lamp source 22 is located at the top of the lamp housing 211. The light-transmitting mask 212 is detachably installed at the opening of the lamp housing 211. The detachable design of the light-transmitting mask 212 allows for the replacement, cleaning, or maintenance of the lamp source 22 without disassembling the entire light-emitting component 2, shortening maintenance time and significantly reducing after-sales maintenance costs. Simultaneously, the U-shaped design of the lamp housing 211 ensures that the light-transmitting mask 212 can be installed quickly and accurately, avoiding assembly errors associated with traditional fixed masks and improving production line efficiency. The downward-facing opening of the lamp housing 211 also effectively prevents rainwater, dust, and other foreign objects from entering the lamp housing through the opening, significantly improving the reliability of the product under harsh weather conditions.

[0055] In this example, the translucent surface of the light-transmitting mask 212 is etched with texture to change the intensity of light transmission.

[0056] like Figure 3 and Figure 9 As shown, in some optional embodiments, the grille assembly 1 is provided with a plurality of fixing points 15, and the lamp housing 211 is provided with a connecting frame 23 corresponding to the fixing points 15. The connecting frame 23 is connected to the fixing points 15 by bolts 4.

[0057] In this embodiment, the grille assembly 1 is provided with multiple fixing points 15, and the lamp housing 211 is provided with a connecting frame 23 corresponding to the fixing points 15. The connecting frame 23 is connected to the fixing points 15 by bolts 4. The layout of the multiple fixing points 15 and the precise correspondence of the connecting frame 23 make the installation position of the lamp housing 211 on the grille assembly 1 precisely controllable. Furthermore, the multiple fixing points 15 are distributed on the grille assembly 1, and with the multi-point support of the connecting frame 23, the force on the lamp housing 211 is more balanced and the stability is better.

[0058] like Figure 3 and Figure 9 As shown, in some optional embodiments, some fixing points 15 are located above the light-receiving part 12, and the remaining fixing points 15 are located within the area where the light-receiving part 12 is located.

[0059] In this embodiment, some fixing points 15 are located above the light-receiving part 12, and the remaining fixing points 15 are located within the area where the light-receiving part 12 is located. Some fixing points above the light-receiving part 12 form an upper support, and the remaining fixing points within the area where the light-receiving part 12 is located form a lower fixation, thus realizing a dual support structure for the light-emitting component 2. This layout makes the stress distribution more uniform and improves the vibration resistance.

[0060] like Figure 1 , Figure 3 and Figure 4 As shown, in some optional embodiments, the grille assembly 1 includes: The inner grille panel 16 is used to connect with the skin 3. The inner grille panel 16 is provided with an air intake 11 and a light-receiving part 12. The light-emitting component 2 is connected to the inner side of the inner grille panel 16. The outer panel 17 of the grille is located on the outside of the inner panel 16 of the grille. The outer panel 17 of the grille is provided with a light-transmitting air intake, which is used to cooperate with the air intake 11 to intake air and to transmit the light reflected by the light-receiving part 12.

[0061] In this embodiment, the structure of the grille assembly 1 is specifically described. The grille assembly 1 includes an inner grille plate 16 and an outer grille plate 17. The inner grille plate 16 is used to connect with the skin 3. The inner grille plate 16 is provided with an air intake 11 and a light-receiving part 12. The light-emitting component 2 is connected to the inner side of the inner grille plate 16. The outer grille plate 17 is located on the outer side of the inner grille plate 16. The outer grille plate 17 is provided with a light-transmitting air intake, which is used to cooperate with the air intake 11 to intake air and to transmit light reflected by the light-receiving part 12. The double-layer structure design of the inner grille plate 16 and the outer grille plate 17 perfectly integrates the air intake function and the light transmission function in space. The light-transmitting air intake on the outer grille plate 17 not only cooperates with the air intake 11 to achieve efficient air intake, but also transmits light reflected by the light-receiving part 12. Furthermore, the double-layer structure design improves the overall strength of the grille assembly 1.

[0062] In this example, the outer grille panel 17 embodies the design and can meet a variety of appearance requirements such as painting and electroplating.

[0063] like Figure 6 and Figure 8 As shown, in some optional embodiments, the air intake 11 includes a left air intake 161 and a right air intake 162 spaced apart. The upper sides of the left air intake 161 and the right air intake 162 are both arc-shaped, and the upper height of the left air intake 161 and the right air intake 162 at the ends away from each other is higher than the upper height of the ends close to each other.

[0064] In this embodiment, the air intake 11 includes a left air intake 161 and a right air intake 162 spaced apart. The upper sides of both the left and right air intakes 161 and 162 are arc-shaped, and the upper height of the ends of the left and right air intakes 161 and 162 that are farther from each other is higher than the upper height of the ends that are closer to each other. The arc-shaped upper side design combined with the height variation optimizes the airflow path and avoids interference with the light reflection of the light-receiving part 12. Furthermore, the higher upper height of the ends of the left and right air intakes 161 and 162 that are farther from each other provides more space for the installation of other components in the grille assembly 1, resulting in better space utilization.

[0065] like Figure 1 , Figure 3 , Figure 4 and Figure 8 As shown, in some optional embodiments, light-emitting components 2 are provided above the left air intake 161 and the right air intake 162, and each light-emitting component 2 is connected to a corresponding electrical control box 5, which is located inside the inner panel 16 of the grille.

[0066] In this embodiment, light-emitting components 2 are provided above both the left air intake 161 and the right air intake 162. Each light-emitting component 2 is connected to a corresponding electrical control box 5, which is located inside the grille inner panel 16. Each light-emitting component 2 is equipped with an independent electrical control box 5, allowing the lighting effects on the left and right sides to be controlled independently, realizing multi-mode lighting effect interaction. The electrical control box 5 is located inside the grille inner panel 16, away from the external environment, effectively preventing the intrusion of rainwater, dust, and other foreign objects, and forms an integrated layout with the light-emitting components 2, avoiding the space occupied by additional wiring harnesses and control modules.

[0067] like Figure 1 and Figure 3 As shown, in some optional embodiments, two electrical control boxes 5 are respectively located above the left air inlet 161 and the right air inlet 162, close to each other at one end.

[0068] In this embodiment, the two electrical control boxes 5 are respectively located above the left air inlet 161 and the right air inlet 162, close to each other. By placing the electrical control boxes 5 above the air inlets, the space between the air inlets is cleverly utilized, avoiding additional occupation of the internal space of the grille assembly 1. Furthermore, this layout allows the position of the electrical control boxes 5 to work synergistically with the air inlet 11. When the airflow passes through the air inlet, it not only provides heat dissipation for the electrical control boxes 5, but also does not interfere with the light reflection path of the light-emitting component 2.

[0069] like Figure 1 and Figure 2 As shown, in some optional embodiments, the outer grille panel 17 is provided with a plurality of elongated holes 171 arranged along the height direction. The plurality of elongated holes 171 are spaced apart along the vehicle width direction to form a light-transmitting air intake. The projection area of ​​the elongated holes 171 partially overlaps with the area where the air intake 11 and the light-receiving part 12 are located.

[0070] In this embodiment, the outer grille panel 17 is provided with a plurality of elongated holes 171 arranged along the height direction. The plurality of elongated holes 171 are spaced apart along the width direction of the vehicle to form a light-transmitting air intake. The projection area of ​​the elongated holes 171 partially overlaps with the area where the air intake 11 and the light-receiving part 12 are located. The design that the projection area of ​​the elongated holes 171 partially overlaps with the area where the air intake 11 and the light-receiving part 12 are located allows the outer grille panel 17 to achieve efficient light transmission while maintaining the integrity of the air intake channel.

[0071] like Figure 2 As shown, in some optional embodiments, the number of elongated holes 171 is greater than the number of light-transmitting holes 13, and some elongated holes 171 correspond to light-transmitting holes 13, with the light-transmitting holes 13 located within the projection area of ​​the corresponding elongated hole 171.

[0072] In this embodiment, the number of elongated holes 171 is greater than the number of light-transmitting holes 13, and some elongated holes 171 correspond to light-transmitting holes 13, with the light-transmitting holes 13 located within the projection area of ​​the corresponding elongated hole 171. The greater number of elongated holes 171 than light-transmitting holes 13 significantly increases the number of air intake channels, ensuring heat dissipation. The light-transmitting holes 13 are located within the projection area of ​​the elongated holes 171, allowing light to pass through the elongated holes 171 precisely, enabling the outer grille panel 17 to achieve efficient light transmission while maintaining the integrity of the air intake channels.

[0073] like Figure 1 , Figure 3 and Figure 4 As shown, this application also provides a design method for a light-emitting grille, which is used to design the aforementioned light-emitting grille, including the following steps: Establish an optical simulation model of the light-emitting grating; Adjust the structural parameters of the light-emitting grid in the optical simulation model, as well as the distance between the grid component 1 and the skin 3, to obtain the structural parameters and distance corresponding to the expected light reflection and transmission effect; Based on the structural parameters and spacing, the light-emitting component 2 is installed onto the grille component 1.

[0074] In designing this luminous grille, grille assembly 1 is used to connect with skin 3. Grille assembly 1 has an air inlet 11 and a light-receiving part 12 located above the air inlet 11. The luminous component 2 is disposed between grille assembly 1 and skin 3, connected to grille assembly 1 and located above the light-receiving part 12. The light emitted by the luminous component 2 is reflected by the light-receiving part 12 and then passes through grille assembly 1. In designing this luminous grille, an optical simulation model of the luminous grille is established; the structural parameters of the luminous grille in the optical simulation model, as well as the distance between grille assembly 1 and skin 3, are adjusted to obtain the structural parameters and distance corresponding to the expected reflection and transmission effect; according to the structural parameters and distance, the luminous component 2 is installed on grille assembly 1. Because the grille assembly 1 has an air intake 11 and the light-emitting component 2 is located between the grille assembly 1 and the skin 3, the light emitted by the light-emitting component 2 is reflected by the light-receiving part 12 and then passes through the grille assembly 1. The light-receiving structure design allows the light emitted by the light-emitting component 2 to pass through the grille assembly 1 after being reflected by the light-receiving part 12, which improves the light efficiency, enhances the visual effect, makes the lighting effect brighter and more uniform, and improves the aesthetics and recognizability of the front of the vehicle. By setting the air intake 11 on the grille assembly 1, the air intake and heat dissipation needs of the front of the vehicle are met, and the lighting effect interaction function is realized. The air intake needs and lighting effect interaction are harmoniously unified, which solves the problem that the existing light-emitting grille does not have an air intake, has poor heat dissipation performance, and is difficult to meet the air intake and heat dissipation requirements when used in larger new energy vehicles, and there is a problem that it is difficult to achieve lighting effect interaction under the premise of ensuring air intake needs.

[0075] In some optional embodiments, adjusting the structural parameters of the light-emitting grating in the optical simulation model, as well as the distance between the grating assembly 1 and the skin 3, to obtain the structural parameters and distance corresponding to the expected reflection and transmission effect includes: Adjust the angle between the light source 22 emitting panel and the light-receiving plate 141, and the angle between the light-receiving plate 141 and the horizontal plane to obtain the angle between the light source 22 emitting panel and the light-receiving plate 141 and the angle between the light-receiving plate 141 and the horizontal plane corresponding to the expected reflection effect. Adjust the distance between the light source 22 and the inner panel 16 of the grille, and the distance between the elongated hole 171 of the outer panel 17 of the grille and the light-receiving plate 141, to obtain the distance between the light source 22 and the inner panel 16 of the grille, and the distance between the elongated hole 171 of the outer panel 17 of the grille and the light-receiving plate 141 corresponding to the expected light transmission effect.

[0076] In this embodiment, the structural parameters of the light-emitting grid in the optical simulation model, as well as the distance between the grid assembly 1 and the skin 3, are adjusted to obtain the structural parameters and distances corresponding to the expected reflection and light transmission effect. Specifically, this includes: adjusting the angle between the light-emitting panel of the lamp source 22 and the light-receiving plate 141, and the angle between the light-receiving plate 141 and the horizontal plane, to obtain the angles between the light-emitting panel of the lamp source 22 and the light-receiving plate 141, and the angle between the light-receiving plate 141 and the horizontal plane corresponding to the expected reflection effect; adjusting the distance between the lamp source 22 and the inner plate 16 of the grid, and the distance between the elongated hole 171 of the outer plate 17 of the grid and the light-receiving plate 141, to obtain the distance between the lamp source 22 and the inner plate 16 of the grid, and the distance between the elongated hole 171 of the outer plate 17 of the grid and the light-receiving plate 141 corresponding to the expected light transmission effect. Adjusting the parameters corresponding to the expected reflection effect and the parameters corresponding to the expected light transmission effect separately allows for faster adjustment, a clearer adjustment process, and improved design efficiency.

[0077] In some optional embodiments, if the distance between the light source 22 and the inner plate 16 of the grille corresponding to the desired light transmission effect is greater than the maximum distance between the light source 22 and the inner plate 16 of the grille, the distance between the light source 22 and the inner plate 16 of the grille, as well as the distance between the elongated hole 171 of the outer plate 17 of the grille and the light-bearing plate 141, are readjusted.

[0078] In this embodiment, if the distance between the light source 22 and the inner grille panel 16 corresponding to the desired light transmission effect is greater than the maximum distance between the light source 22 and the inner grille panel 16, the distance between the light source 22 and the inner grille panel 16, as well as the distance between the elongated hole 171 of the outer grille panel 17 and the light-receiving plate 141, are readjusted. When the desired distance between the light source 22 and the inner grille panel 16 exceeds the maximum allowable value, the system readjusts the relevant parameters to optimize the light transmission effect within a feasible range, ensuring optimal product performance. This ensures that all design parameters are within the feasible range for actual manufacturing, avoiding design failures caused by theoretically calculated parameters exceeding physical limitations, and significantly improving the success rate and efficiency of product development.

[0079] like Figures 1-10 As shown, this application also provides a front bumper assembly, which includes: Skin 3; The grille assembly 1 is connected to the skin 3. The grille assembly 1 is provided with an air intake 11 and a light-receiving part 12 located above the air intake 11. The light-emitting component 2 is disposed between the grille component 1 and the skin 3. The light-emitting component 2 is connected to the grille component 1 and is located above the light-receiving part 12. The light emitted by the light-emitting component 2 is reflected by the light-receiving part 12 and then passes through the grille component 1.

[0080] In designing this luminous grille, grille assembly 1 is used to connect with skin 3. Grille assembly 1 has an air inlet 11 and a light-receiving part 12 located above the air inlet 11. The luminous component 2 is disposed between grille assembly 1 and skin 3, connected to grille assembly 1 and located above the light-receiving part 12. The light emitted by the luminous component 2 is reflected by the light-receiving part 12 and then passes through grille assembly 1. In designing this luminous grille, an optical simulation model of the luminous grille is established; the structural parameters of the luminous grille in the optical simulation model, as well as the distance between grille assembly 1 and skin 3, are adjusted to obtain the structural parameters and distance corresponding to the expected reflection and transmission effect; according to the structural parameters and distance, the luminous component 2 is installed on grille assembly 1. Because the grille assembly 1 has an air intake 11 and the light-emitting component 2 is located between the grille assembly 1 and the skin 3, the light emitted by the light-emitting component 2 is reflected by the light-receiving part 12 and then passes through the grille assembly 1. The light-receiving structure design allows the light emitted by the light-emitting component 2 to pass through the grille assembly 1 after being reflected by the light-receiving part 12, which improves the light efficiency, enhances the visual effect, makes the lighting effect brighter and more uniform, and improves the aesthetics and recognizability of the front of the vehicle. By setting the air intake 11 on the grille assembly 1, the air intake and heat dissipation needs of the front of the vehicle are met, and the lighting effect interaction function is realized. The air intake needs and lighting effect interaction are harmoniously unified, which solves the problem that the existing light-emitting grille does not have an air intake, has poor heat dissipation performance, and is difficult to meet the air intake and heat dissipation requirements when used in larger new energy vehicles, and there is a problem that it is difficult to achieve lighting effect interaction under the premise of ensuring air intake needs.

[0081] In this embodiment, the grille assembly 1 has multiple spaced-apart light-transmitting holes 13 located above the air intake 11. Each light-transmitting hole 13 has a light-receiving structure 14, the light-receiving surface of which is located below the light-emitting component 2, and the light-receiving surface forms a set angle with the light source orientation of the light-emitting component 2 in its vertical section. All light-receiving structures 14 together form a light-receiving section 12. The multiple spaced-apart light-transmitting holes 13, together with the light-receiving structures 14, form a continuous light-receiving section 12. The set angle enables directional reflection of light, giving the lighting effect a three-dimensional and layered visual effect. All the light-receiving structures 14 work together to eliminate the fragmented feeling of single-point light transmission, enhance the overall aesthetics and brand recognition of the vehicle's front face, and meet the stringent requirements of high-end models for artistic lighting effects. The special layout of the light-transmitting hole 13 located above the air intake 11 does not affect the air intake function and ensures the light transmission effect of the light-bearing part 12. The design of the light-bearing surface of the light-bearing structure 14 located below the light-emitting component 2 avoids the obstruction of light in the air intake area. This solves the problem that the existing light-emitting grille does not have an air intake, has poor heat dissipation performance, and is difficult to meet the air intake heat dissipation requirements when used in larger new energy vehicles, thus making it difficult to achieve interactive lighting effects under the premise of ensuring air intake requirements.

[0082] In this embodiment, the specific construction of the light-receiving structure 14 is described. The light-receiving structure 14 includes a light-receiving plate 141 and two connecting plates 142 respectively disposed on both sides of the light-receiving plate 141. The light-receiving plate 141 is inclined, with its upper surface serving as the light-receiving surface. The lower end of the light-receiving plate 141 is connected to the lower side of the light-transmitting hole 13, and the upper end is located inside the grille assembly 1. The width of the light-receiving plate 141 is less than or equal to the width of the light-transmitting hole 13. Both connecting plates 142 are connected to the inner side of the grille assembly 1 and are located at the edge of the light-transmitting hole 13. Both connecting plates 142 are connected to the inner side of the grille assembly 1 and located at the edge of the light-transmitting hole 13, forming a stable support frame. This effectively prevents the light-receiving plate 141 from shifting or deforming under vibration or temperature changes. At the same time, it simplifies the installation process, allowing the light-receiving structure 14 to be quickly and accurately fixed at the light-transmitting hole 13, significantly improving assembly efficiency and product reliability. The light-receiving plate 141 is tilted and its upper surface serves as the light-receiving surface. Its tilt angle can be precisely matched with the light source orientation of the light-emitting component 2, ensuring that the light achieves the best reflection path on the light-receiving plate 141.

[0083] In this embodiment, the arrangement of all the light-transmitting holes 13 matches the upper shape of the air intake 11. Because the arrangement of the light-transmitting holes 13 matches the upper shape of the air intake 11, light can maintain a consistent reflection path when passing through the light-transmitting holes 13, avoiding the problem of uneven light effect caused by irregular hole positions. Combined with the optimized design of the light-receiving structure 14, the lighting effect forms a continuous and uniform luminous effect above the air intake 11, enhancing the refinement and artistic expression of the lighting effect, and creating a smooth visual transition, avoiding the visual defect of a separation between the air intake structure and the light-transmitting structure in traditional designs. This matching not only ensures functional requirements but also enhances the overall aesthetics of the vehicle's front end, creating a harmonious and unified artistic expression between the lighting effect and the air intake structure, enhancing the vehicle's recognizability and premium feel.

[0084] In this embodiment, the specific structure of the light-emitting component 2 is described. The light-emitting component 2 includes a mounting shell 21 and a light source 22. The mounting shell 21 is connected to the inner side of the grille assembly 1 and is located above the light-receiving part 12. The lower shape of the mounting shell 21 matches the shape of the light-receiving part 12. The light source 22 is disposed inside the mounting shell 21 and is used to emit light that illuminates the light-receiving part 12. The precise matching of the lower shape of the mounting shell 21 with the shape of the light-receiving part 12 ensures that the light emitted by the light source 22 can accurately illuminate the light-receiving part 12 and ensures that the light illumination angle at all the light-transmitting holes 13 is consistent, resulting in a high degree of consistency in the light effect of the entire light-receiving part 12. Furthermore, the design of connecting the mounting shell 21 to the inner side of the grille assembly 1 achieves a high degree of integration between the light-emitting component 2 and the grille assembly 1, reducing the number of parts, simplifying the assembly process, and reducing space occupation.

[0085] In this embodiment, the specific structure of the mounting housing 21 is described. The mounting housing 21 includes a lamp housing 211 and a light-transmitting mask 212. The lamp housing 211 has a U-shaped cross-section with its opening facing downwards. The lamp source 22 is located at the top of the lamp housing 211. The light-transmitting mask 212 is detachably installed at the opening of the lamp housing 211. The detachable design of the light-transmitting mask 212 allows for the replacement, cleaning, or maintenance of the lamp source 22 without disassembling the entire light-emitting component 2, shortening maintenance time and significantly reducing after-sales maintenance costs. Simultaneously, the U-shaped design of the lamp housing 211 ensures that the light-transmitting mask 212 can be installed quickly and accurately, avoiding assembly errors associated with traditional fixed masks and improving production line efficiency. The downward-facing opening of the lamp housing 211 also effectively prevents rainwater, dust, and other foreign objects from entering the lamp housing through the opening, significantly improving the reliability of the product under harsh weather conditions.

[0086] In this embodiment, the grille assembly 1 is provided with multiple fixing points 15, and the lamp housing 211 is provided with a connecting frame 23 corresponding to the fixing points 15. The connecting frame 23 is connected to the fixing points 15 by bolts 4. The layout of the multiple fixing points 15 and the precise correspondence of the connecting frame 23 make the installation position of the lamp housing 211 on the grille assembly 1 precisely controllable. Furthermore, the multiple fixing points 15 are distributed on the grille assembly 1, and with the multi-point support of the connecting frame 23, the force on the lamp housing 211 is more balanced and the stability is better.

[0087] In this embodiment, some fixing points 15 are located above the light-receiving part 12, and the remaining fixing points 15 are located within the area where the light-receiving part 12 is located. Some fixing points above the light-receiving part 12 form an upper support, and the remaining fixing points within the area where the light-receiving part 12 is located form a lower fixation, thus realizing a dual support structure for the light-emitting component 2. This layout makes the stress distribution more uniform and improves the vibration resistance.

[0088] In this embodiment, the structure of the grille assembly 1 is specifically described. The grille assembly 1 includes an inner grille plate 16 and an outer grille plate 17. The inner grille plate 16 is used to connect with the skin 3. The inner grille plate 16 is provided with an air intake 11 and a light-receiving part 12. The light-emitting component 2 is connected to the inner side of the inner grille plate 16. The outer grille plate 17 is located on the outer side of the inner grille plate 16. The outer grille plate 17 is provided with a light-transmitting air intake, which is used to cooperate with the air intake 11 to intake air and to transmit light reflected by the light-receiving part 12. The double-layer structure design of the inner grille plate 16 and the outer grille plate 17 perfectly integrates the air intake function and the light transmission function in space. The light-transmitting air intake on the outer grille plate 17 not only cooperates with the air intake 11 to achieve efficient air intake, but also transmits light reflected by the light-receiving part 12. Furthermore, the double-layer structure design improves the overall strength of the grille assembly 1.

[0089] In this embodiment, the air intake 11 includes a left air intake 161 and a right air intake 162 spaced apart. The upper sides of both the left and right air intakes 161 and 162 are arc-shaped, and the upper height of the ends of the left and right air intakes 161 and 162 that are farther from each other is higher than the upper height of the ends that are closer to each other. The arc-shaped upper side design combined with the height variation optimizes the airflow path and avoids interference with the light reflection of the light-receiving part 12. Furthermore, the higher upper height of the ends of the left and right air intakes 161 and 162 that are farther from each other provides more space for the installation of other components in the grille assembly 1, resulting in better space utilization.

[0090] In this embodiment, light-emitting components 2 are provided above both the left air intake 161 and the right air intake 162. Each light-emitting component 2 is connected to a corresponding electrical control box 5, which is located inside the grille inner panel 16. Each light-emitting component 2 is equipped with an independent electrical control box 5, allowing the lighting effects on the left and right sides to be controlled independently, realizing multi-mode lighting effect interaction. The electrical control box 5 is located inside the grille inner panel 16, away from the external environment, effectively preventing the intrusion of rainwater, dust, and other foreign objects, and forms an integrated layout with the light-emitting components 2, avoiding the space occupied by additional wiring harnesses and control modules.

[0091] In this embodiment, the two electrical control boxes 5 are respectively located above the left air inlet 161 and the right air inlet 162, close to each other. By placing the electrical control boxes 5 above the air inlets, the space between the air inlets is cleverly utilized, avoiding additional occupation of the internal space of the grille assembly 1. Furthermore, this layout allows the position of the electrical control boxes 5 to work synergistically with the air inlet 11. When the airflow passes through the air inlet, it not only provides heat dissipation for the electrical control boxes 5, but also does not interfere with the light reflection path of the light-emitting component 2.

[0092] In this embodiment, the outer grille panel 17 is provided with a plurality of elongated holes 171 arranged along the height direction. The plurality of elongated holes 171 are spaced apart along the width direction of the vehicle to form a light-transmitting air intake. The projection area of ​​the elongated holes 171 partially overlaps with the area where the air intake 11 and the light-receiving part 12 are located. The design that the projection area of ​​the elongated holes 171 partially overlaps with the area where the air intake 11 and the light-receiving part 12 are located allows the outer grille panel 17 to achieve efficient light transmission while maintaining the integrity of the air intake channel.

[0093] In this embodiment, the number of elongated holes 171 is greater than the number of light-transmitting holes 13, and some elongated holes 171 correspond to light-transmitting holes 13, with the light-transmitting holes 13 located within the projection area of ​​the corresponding elongated hole 171. The greater number of elongated holes 171 than light-transmitting holes 13 significantly increases the number of air intake channels, ensuring heat dissipation. The light-transmitting holes 13 are located within the projection area of ​​the elongated holes 171, allowing light to pass through the elongated holes 171 precisely, enabling the outer grille panel 17 to achieve efficient light transmission while maintaining the integrity of the air intake channels.

[0094] like Figure 4 and Figure 10 As shown, in some optional embodiments, the light-bearing part 12 is formed by all the light-bearing structures 14. The light-bearing structure 14 includes a light-bearing plate 141 and two connecting plates 142 respectively disposed on both sides of the light-bearing plate 141. A horizontally disposed shielding plate 18 is provided on the lower side of the light-bearing plate 141. An extension plate 31 protruding into the light-bearing plate 141 is provided on the upper part of the skin 3. The extension plate 31 is disposed horizontally and is located above the shielding plate 18, and partially extends into the projection range of the shielding plate 18 in the vertical direction.

[0095] In this embodiment, the light-receiving part 12 is formed by all the light-receiving structures 14. The light-receiving structure 14 includes a light-receiving plate 141 and two connecting plates 142 respectively disposed on both sides of the light-receiving plate 141. A horizontally arranged shielding plate 18 is provided on the lower side of the light-receiving plate 141. An extension plate 31 protruding inward toward the light-receiving plate 141 is provided on the upper part of the skin 3. The extension plate 31 is arranged horizontally and is located above the shielding plate 18, and partially extends into the vertical projection range of the shielding plate 18. The cooperative design of the shielding plate 18 and the extension plate 31 effectively prevents light from leaking from below the light-receiving plate 141, preventing light from leaking into the interior of the grille and illuminating internal structures such as the radiator, thus preventing structural exposure.

[0096] In this example, the angle α between the light source 22 and the light-receiving plate 141 is between 22° and 23°, the angle β between the light-receiving plate 141 and the horizontal plane is about 60° to 62°, the distance between the light source 22 and the inner plate 16 of the grille is 2-2.5mm, and the distance b between the elongated hole 171 of the outer plate 17 of the grille and the light-receiving plate 141 is about 10mm, in order to achieve the best light effect.

[0097] like Figures 1-10 As shown, on the other hand, this application also provides a vehicle that includes the aforementioned luminous grille.

[0098] In designing this luminous grille, grille assembly 1 is used to connect with skin 3. Grille assembly 1 has an air inlet 11 and a light-receiving part 12 located above the air inlet 11. The luminous component 2 is disposed between grille assembly 1 and skin 3, connected to grille assembly 1 and located above the light-receiving part 12. The light emitted by the luminous component 2 is reflected by the light-receiving part 12 and then passes through grille assembly 1. In designing this luminous grille, an optical simulation model of the luminous grille is established; the structural parameters of the luminous grille in the optical simulation model, as well as the distance between grille assembly 1 and skin 3, are adjusted to obtain the structural parameters and distance corresponding to the expected reflection and transmission effect; according to the structural parameters and distance, the luminous component 2 is installed on grille assembly 1. Because the grille assembly 1 has an air intake 11 and the light-emitting component 2 is located between the grille assembly 1 and the skin 3, the light emitted by the light-emitting component 2 is reflected by the light-receiving part 12 and then passes through the grille assembly 1. The light-receiving structure design allows the light emitted by the light-emitting component 2 to pass through the grille assembly 1 after being reflected by the light-receiving part 12, which improves the light efficiency, enhances the visual effect, makes the lighting effect brighter and more uniform, and improves the aesthetics and recognizability of the front of the vehicle. By setting the air intake 11 on the grille assembly 1, the air intake and heat dissipation needs of the front of the vehicle are met, and the lighting effect interaction function is realized. The air intake needs and lighting effect interaction are harmoniously unified, which solves the problem that the existing light-emitting grille does not have an air intake, has poor heat dissipation performance, and is difficult to meet the air intake and heat dissipation requirements when used in larger new energy vehicles, and there is a problem that it is difficult to achieve lighting effect interaction under the premise of ensuring air intake needs.

[0099] In this embodiment, the grille assembly 1 has multiple spaced-apart light-transmitting holes 13 located above the air intake 11. Each light-transmitting hole 13 has a light-receiving structure 14, the light-receiving surface of which is located below the light-emitting component 2, and the light-receiving surface forms a set angle with the light source orientation of the light-emitting component 2 in its vertical section. All light-receiving structures 14 together form a light-receiving section 12. The multiple spaced-apart light-transmitting holes 13, together with the light-receiving structures 14, form a continuous light-receiving section 12. The set angle enables directional reflection of light, giving the lighting effect a three-dimensional and layered visual effect. All the light-receiving structures 14 work together to eliminate the fragmented feeling of single-point light transmission, enhance the overall aesthetics and brand recognition of the vehicle's front face, and meet the stringent requirements of high-end models for artistic lighting effects. The special layout of the light-transmitting hole 13 located above the air intake 11 does not affect the air intake function and ensures the light transmission effect of the light-bearing part 12. The design of the light-bearing surface of the light-bearing structure 14 located below the light-emitting component 2 avoids the obstruction of light in the air intake area. This solves the problem that the existing light-emitting grille does not have an air intake, has poor heat dissipation performance, and is difficult to meet the air intake heat dissipation requirements when used in larger new energy vehicles, thus making it difficult to achieve interactive lighting effects under the premise of ensuring air intake requirements.

[0100] In this embodiment, the specific construction of the light-receiving structure 14 is described. The light-receiving structure 14 includes a light-receiving plate 141 and two connecting plates 142 respectively disposed on both sides of the light-receiving plate 141. The light-receiving plate 141 is inclined, with its upper surface serving as the light-receiving surface. The lower end of the light-receiving plate 141 is connected to the lower side of the light-transmitting hole 13, and the upper end is located inside the grille assembly 1. The width of the light-receiving plate 141 is less than or equal to the width of the light-transmitting hole 13. Both connecting plates 142 are connected to the inner side of the grille assembly 1 and are located at the edge of the light-transmitting hole 13. Both connecting plates 142 are connected to the inner side of the grille assembly 1 and located at the edge of the light-transmitting hole 13, forming a stable support frame. This effectively prevents the light-receiving plate 141 from shifting or deforming under vibration or temperature changes. At the same time, it simplifies the installation process, allowing the light-receiving structure 14 to be quickly and accurately fixed at the light-transmitting hole 13, significantly improving assembly efficiency and product reliability. The light-receiving plate 141 is tilted and its upper surface serves as the light-receiving surface. Its tilt angle can be precisely matched with the light source orientation of the light-emitting component 2, ensuring that the light achieves the best reflection path on the light-receiving plate 141.

[0101] In this embodiment, the arrangement of all the light-transmitting holes 13 matches the upper shape of the air intake 11. Because the arrangement of the light-transmitting holes 13 matches the upper shape of the air intake 11, light can maintain a consistent reflection path when passing through the light-transmitting holes 13, avoiding the problem of uneven light effect caused by irregular hole positions. Combined with the optimized design of the light-receiving structure 14, the lighting effect forms a continuous and uniform luminous effect above the air intake 11, enhancing the refinement and artistic expression of the lighting effect, and creating a smooth visual transition, avoiding the visual defect of a separation between the air intake structure and the light-transmitting structure in traditional designs. This matching not only ensures functional requirements but also enhances the overall aesthetics of the vehicle's front end, creating a harmonious and unified artistic expression between the lighting effect and the air intake structure, enhancing the vehicle's recognizability and premium feel.

[0102] In this embodiment, the specific structure of the light-emitting component 2 is described. The light-emitting component 2 includes a mounting shell 21 and a light source 22. The mounting shell 21 is connected to the inner side of the grille assembly 1 and is located above the light-receiving part 12. The lower shape of the mounting shell 21 matches the shape of the light-receiving part 12. The light source 22 is disposed inside the mounting shell 21 and is used to emit light that illuminates the light-receiving part 12. The precise matching of the lower shape of the mounting shell 21 with the shape of the light-receiving part 12 ensures that the light emitted by the light source 22 can accurately illuminate the light-receiving part 12 and ensures that the light illumination angle at all the light-transmitting holes 13 is consistent, resulting in a high degree of consistency in the light effect of the entire light-receiving part 12. Furthermore, the design of connecting the mounting shell 21 to the inner side of the grille assembly 1 achieves a high degree of integration between the light-emitting component 2 and the grille assembly 1, reducing the number of parts, simplifying the assembly process, and reducing space occupation.

[0103] In this embodiment, the specific structure of the mounting housing 21 is described. The mounting housing 21 includes a lamp housing 211 and a light-transmitting mask 212. The lamp housing 211 has a U-shaped cross-section with its opening facing downwards. The lamp source 22 is located at the top of the lamp housing 211. The light-transmitting mask 212 is detachably installed at the opening of the lamp housing 211. The detachable design of the light-transmitting mask 212 allows for the replacement, cleaning, or maintenance of the lamp source 22 without disassembling the entire light-emitting component 2, shortening maintenance time and significantly reducing after-sales maintenance costs. Simultaneously, the U-shaped design of the lamp housing 211 ensures that the light-transmitting mask 212 can be installed quickly and accurately, avoiding assembly errors associated with traditional fixed masks and improving production line efficiency. The downward-facing opening of the lamp housing 211 also effectively prevents rainwater, dust, and other foreign objects from entering the lamp housing through the opening, significantly improving the reliability of the product under harsh weather conditions.

[0104] In this embodiment, the grille assembly 1 is provided with multiple fixing points 15, and the lamp housing 211 is provided with a connecting frame 23 corresponding to the fixing points 15. The connecting frame 23 is connected to the fixing points 15 by bolts 4. The layout of the multiple fixing points 15 and the precise correspondence of the connecting frame 23 make the installation position of the lamp housing 211 on the grille assembly 1 precisely controllable. Furthermore, the multiple fixing points 15 are distributed on the grille assembly 1, and with the multi-point support of the connecting frame 23, the force on the lamp housing 211 is more balanced and the stability is better.

[0105] In this embodiment, some fixing points 15 are located above the light-receiving part 12, and the remaining fixing points 15 are located within the area where the light-receiving part 12 is located. Some fixing points above the light-receiving part 12 form an upper support, and the remaining fixing points within the area where the light-receiving part 12 is located form a lower fixation, thus realizing a dual support structure for the light-emitting component 2. This layout makes the stress distribution more uniform and improves the vibration resistance.

[0106] In this embodiment, the structure of the grille assembly 1 is specifically described. The grille assembly 1 includes an inner grille plate 16 and an outer grille plate 17. The inner grille plate 16 is used to connect with the skin 3. The inner grille plate 16 is provided with an air intake 11 and a light-receiving part 12. The light-emitting component 2 is connected to the inner side of the inner grille plate 16. The outer grille plate 17 is located on the outer side of the inner grille plate 16. The outer grille plate 17 is provided with a light-transmitting air intake, which is used to cooperate with the air intake 11 to intake air and to transmit light reflected by the light-receiving part 12. The double-layer structure design of the inner grille plate 16 and the outer grille plate 17 perfectly integrates the air intake function and the light transmission function in space. The light-transmitting air intake on the outer grille plate 17 not only cooperates with the air intake 11 to achieve efficient air intake, but also transmits light reflected by the light-receiving part 12. Furthermore, the double-layer structure design improves the overall strength of the grille assembly 1.

[0107] In this embodiment, the air intake 11 includes a left air intake 161 and a right air intake 162 spaced apart. The upper sides of both the left and right air intakes 161 and 162 are arc-shaped, and the upper height of the ends of the left and right air intakes 161 and 162 that are farther from each other is higher than the upper height of the ends that are closer to each other. The arc-shaped upper side design combined with the height variation optimizes the airflow path and avoids interference with the light reflection of the light-receiving part 12. Furthermore, the higher upper height of the ends of the left and right air intakes 161 and 162 that are farther from each other provides more space for the installation of other components in the grille assembly 1, resulting in better space utilization.

[0108] In this embodiment, light-emitting components 2 are provided above both the left air intake 161 and the right air intake 162. Each light-emitting component 2 is connected to a corresponding electrical control box 5, which is located inside the grille inner panel 16. Each light-emitting component 2 is equipped with an independent electrical control box 5, allowing the lighting effects on the left and right sides to be controlled independently, realizing multi-mode lighting effect interaction. The electrical control box 5 is located inside the grille inner panel 16, away from the external environment, effectively preventing the intrusion of rainwater, dust, and other foreign objects, and forms an integrated layout with the light-emitting components 2, avoiding the space occupied by additional wiring harnesses and control modules.

[0109] In this embodiment, the two electrical control boxes 5 are respectively located above the left air inlet 161 and the right air inlet 162, close to each other. By placing the electrical control boxes 5 above the air inlets, the space between the air inlets is cleverly utilized, avoiding additional occupation of the internal space of the grille assembly 1. Furthermore, this layout allows the position of the electrical control boxes 5 to work synergistically with the air inlet 11. When the airflow passes through the air inlet, it not only provides heat dissipation for the electrical control boxes 5, but also does not interfere with the light reflection path of the light-emitting component 2.

[0110] In this embodiment, the outer grille panel 17 is provided with a plurality of elongated holes 171 arranged along the height direction. The plurality of elongated holes 171 are spaced apart along the width direction of the vehicle to form a light-transmitting air intake. The projection area of ​​the elongated holes 171 partially overlaps with the area where the air intake 11 and the light-receiving part 12 are located. The design that the projection area of ​​the elongated holes 171 partially overlaps with the area where the air intake 11 and the light-receiving part 12 are located allows the outer grille panel 17 to achieve efficient light transmission while maintaining the integrity of the air intake channel.

[0111] In this embodiment, the number of elongated holes 171 is greater than the number of light-transmitting holes 13, and some elongated holes 171 correspond to light-transmitting holes 13, with the light-transmitting holes 13 located within the projection area of ​​the corresponding elongated hole 171. The greater number of elongated holes 171 than light-transmitting holes 13 significantly increases the number of air intake channels, ensuring heat dissipation. The light-transmitting holes 13 are located within the projection area of ​​the elongated holes 171, allowing light to pass through the elongated holes 171 precisely, enabling the outer grille panel 17 to achieve efficient light transmission while maintaining the integrity of the air intake channels.
