Technical Field
[0001] This utility model relates to the field of automotive parts technology, and in particular to an inner lens component, a three-dimensional light-emitting structure, a three-dimensional light-emitting grille, and an automobile. Background Technology
[0002] In the field of automotive design, illuminated exterior grilles, as an innovative element that blends a sense of technology with brand recognition, are gradually becoming a signature feature of new energy vehicles and high-end models. Their core technical architecture is based on a low-power LED array as the light source. Through the refraction and control of optical lenses or the light transmission of light guide structures, uniform light diffusion is achieved, resulting in a soft and continuous luminous effect. Considering that new energy vehicles do not require the airflow guidance function of traditional air intake grilles, illuminated grilles often adopt a closed, integrated design, embedding the light source components and optical structure entirely within the grille frame. They also utilize materials with excellent weather resistance, such as polycarbonate (PC) and acrylic, and are equipped with efficient heat dissipation modules (such as metal heat sinks and heat pipe conduction systems) to ensure long-term stable operation in complex environments such as high temperatures, extreme cold, rain, and snow.
[0003] Furthermore, the intelligent control system of the illuminated grille links with the vehicle status perception module via the vehicle bus, enabling it to drive the lights to present diverse interactive effects based on the vehicle's dynamic behaviors such as unlocking, turning, charging, and acceleration. Examples include a welcoming flowing animation when the vehicle unlocks, dynamic indicator light strips when turning, charging progress indicator light spots, and the illumination of the brand's exclusive logo. This design not only enhances the vehicle's brand recognition and elevates the sense of luxury in its exterior design, but also addresses energy conservation and environmental protection needs thanks to the low energy consumption of LED light sources, making it a prime example of the fusion of function and aesthetics in modern automotive design.
[0004] Currently, the mainstream light-emitting grilles on the market can be divided into two main categories based on their optical design features: "dot matrix" and "line".
[0005] "Dot-matrix" luminous grilles, exemplified by models like the Mercedes-Benz EQS, are designed to create complex luminous patterns through a large number of repeatedly arranged "point light source features." For instance, hundreds of independently controlled micro-LED point light sources are distributed across the grille surface. Each point light source can be individually turned on / off or its brightness adjusted, and the combination of these points forms brand logos, dynamic patterns, or text information. Figure 1As shown, its optical structure typically comprises four core components: the bottom layer is the "LED circuit board," where densely arranged LED chips provide the basic light source; the middle layer is the "diffuse layer," which uses microstructure texture or frosted treatment to scatter the intense light from individual LEDs, ensuring uniform brightness distribution across each dot matrix; the top layer is the "pattern layer," which defines the light-emitting contours of individual dot matrices through partially transparent cutout designs or selective printing of light-shielding inks, achieving imaging functionality; the outermost layer is the "surface clear coat layer," which uses high-hardness UV paint or ceramic coating processes to enhance the overall gloss of the parts and form a wear-resistant and aging-resistant protective layer to resist external scratches and UV corrosion. However, this point-based light-emitting mode has inherent limitations: since there must be physical intervals between point light sources, and the light-emitting range of a single point light source is limited to a small area within a two-dimensional plane, it is a one-dimensional light-emitting characteristic. Therefore, it is difficult to form a continuous, uninterrupted three-dimensional optical effect. When presenting complex shapes such as curved transitions and three-dimensional reliefs, problems such as light breaks or loss of three-dimensionality can easily occur.
[0006] The "linear" illuminated grille, exemplified by models like the BMW 5 Series, emphasizes the styling lines of the vehicle's front end through linear illumination. For example... Figure 2 As shown, its optical principle is to integrate the LED light source at the end of the "transparent light guide". The light is transmitted through total internal reflection in the light guide. When it encounters the "optical teeth" (i.e. tiny sawtooth protrusions or inclined structures) preset on the side of the light guide, the light is refracted and reflected and emitted from the surface of the light guide. After passing through the secondary light homogenization process of the "diffuser", a continuous linear light-emitting band is formed. However, this solution has three significant drawbacks: First, limited by the light transmission efficiency of the light guide, the "linear light source" typically only has 1 to 2 LED heads at both ends of the light guide. After the light undergoes multiple "optical tooth reflections" and scattering by the "diffuser," the energy loss is significant, resulting in a generally low overall brightness, mostly around 200 nits. In strong daylight conditions, it is easily obscured by background light, significantly reducing its visibility. Second, when the daytime lights are off, the exposed "diffuser" (mostly made of milky white or semi-transparent material) differs significantly in color and texture from the surrounding chrome trim and black grille, failing to blend into the overall design and instead creating a visual break, weakening the sense of sophistication of the front design. Third, the light trajectory of the "linear light source" relies entirely on the linear direction of the light guide, only able to display a two-dimensional optical spline shape in a plane, making it difficult to achieve a three-dimensional structure with spatial undulations, let alone present complex curved surface lighting effects, thus limiting the expression of design creativity.
[0007] In summary, existing "dot matrix" and "line" luminous grilles have obvious shortcomings in terms of optical performance and styling integration: either the spacing of the point light sources leads to a lack of three-dimensional effect, or the insufficient brightness and disjointed styling affect the user experience. Moreover, they generally cannot achieve an integrated design without openings or seams, making it difficult to meet the pursuit of continuous three-dimensional luminous effect and overall styling in high-end models.
[0008] Currently, no effective solutions have been proposed for the problems existing in related technologies, such as the presence of partial or slit openings, poor overall shape, and inability to achieve three-dimensional light-emitting effects. Utility Model Content

The plurality of recessed teeth 231 are spaced apart along a first extending direction of the reflective element 220, and each recessed tooth 231 extends along a second extending direction of the reflective element 220, wherein the second extending direction is not parallel to the first extending direction.
[0107] The first extending direction is the rear-to-front direction of the reflective element 220, and the second extending direction is the top-to-bottom direction of the reflective element 220.
[0108] Generally, a number of concave teeth 231 are arranged to cover the reflective element 220.
[0109] The concave tooth 231 can be set perpendicular to the side end face of the reflective element 220, or it can be set at a certain angle to the side end face of the reflective element 220 (i.e., tilted).

[0113] In some of these embodiments, a plurality of concave teeth 231 are distributed at equal intervals.
[0114] In some embodiments, the concave teeth 231 are distributed with non-uniform spacing. This non-uniform spacing includes either a regular change in the spacing between adjacent concave teeth 231 along a first extending direction, or an irregular change in the spacing between adjacent concave teeth 231 along the first extending direction.
[0115] Regular changes are those that occur in only one direction, such as increasing or decreasing.
[0116] Among them, irregular changes are any combination of increasing, decreasing, and constant values, such as increasing + decreasing combination, increasing + constant combination, decreasing + constant combination, increasing + decreasing + constant combination.

[0135] Within each combination, the order can be arbitrary. Taking the increasing + decreasing combination as an example, it can be increasing first and then decreasing, decreasing first and then increasing, or increasing and decreasing alternately.
[0136] In some of these embodiments, at least one depth variation relationship differs from the others.
[0137] In one specific embodiment of the present invention, the optical pattern element 230 includes three patterned regions 232 arranged sequentially. The width of the first patterned region 232 is 1 / 4 of the width of the optical pattern element 230, the width of the second patterned region 232 is 1 / 4 of the width of the optical pattern element 230, and the width of the third patterned region 232 is 1 / 2 of the width of the optical pattern element 230.

[0138] The optical principle of this invention is as follows:
[0139] The light source emits a first light source parallel to the light-emitting surface (which includes several first rays parallel to the light-emitting surface) and a second light source intersecting the light-emitting surface (which includes several second rays intersecting the light-emitting surface);
[0140] Several first rays and several second rays are mixed in the light mixing element 210. Through light mixing, the dispersion of the light source entering the reflective element 220 is high, thereby improving the sidewall brightness of the subsequent structure.
[0141] Several second rays generate reflected rays at the reflective element 220, and the reflected rays shine outward from both sides of the inner lens component 200, thereby forming a lateral optical effect.
[0142] The technical effects of this utility model are as follows:
[0143] By combining the light mixing effect of the light mixing element with the reflection effect of the reflection element, the brightness of the sidewalls of the subsequent structure can be improved, and a lateral optical effect can be formed, thus making the subsequent structure present a three-dimensional light emission effect.
[0144] Example 2
[0145] This embodiment relates to the three-dimensional light-emitting structure of this utility model.
[0146] An illustrative embodiment of this utility model, such as Figures 5-7 As shown, a three-dimensional light-emitting structure includes a lampshade component 100, an inner lens component 200 as described in Embodiment 1, and a light-emitting component 300. At least a portion of the reflective element 220 of the inner lens component 200 is embedded at the rear end of the lampshade component 100; the light-emitting component 300 is disposed upstream of the inner lens component 200 and is used to emit a first light source parallel to the light-emitting surface and a second light source intersecting the light-emitting surface.
[0147] The first light source passes through the inner lens component 200 and enters the lampshade component 100 to form a positive optical effect, while the second light source is reflected by the inner lens component 200 and enters the lampshade component 100 to form a lateral optical effect.
[0148] In this invention, the first light source includes a plurality of first rays parallel to the light-emitting surface, and the second light source includes a plurality of second rays intersecting the light-emitting surface.
[0149] Several first rays and several second rays are mixed in the light mixing element 210. Through light mixing, the light source entering the reflective element 220 has high dispersion, thus avoiding poor brightness uniformity of the side wall of the lampshade component 100.
[0150] Several second rays generate reflected rays at the reflective element 220. The reflected rays illuminate the sides of the lampshade component 100 from both sides of the inner lens component 200. After the uniform light effect of the lampshade component 100, a lateral optical effect is formed.
[0151] like Figure 8 As shown, the lampshade component 100 includes an intrusion element 110, a diffusion element 120, and a through-slot element 130.

[0152] In this invention, the intrusion element 110, the diffusion element 120, and the through-slot element 130 are prepared by conventional machining methods, including but not limited to integral molding, stamping, and cutting processes.
[0153] In some embodiments, the lampshade component 100 is made of PC material and has a diffusion effect.
[0154] In some embodiments, the lampshade component 100 includes, but is not limited to, an outer lampshade.
[0155] Generally, the intrusion element 110 has a front end face, a rear end face, a left end face, a right end face, a top end face, and a bottom end face.

[0162] Furthermore, each end face of the diffusion element 120 can be a continuous surface or a discontinuous surface (such as a stepped surface).
[0163] There is an angle between the left end face (right end face) and the front end face, which can be any one of acute angle, right angle, or obtuse angle.
[0164] There is an included angle between the left end face (right end face) and the rear end face. This included angle can be any one of acute angle, right angle, or obtuse angle.
[0165] Generally, the left and right end faces are symmetrical about the front end face.
[0166] In some of these embodiments, the diffusion element 120 is the diffusion region of the lampshade component 100.
[0167] For the intrusion element 110, the brightness of the intrusion element 110 can at least reach the brightness of the sidewall of the diffusion element 120.
[0168] For the diffuser element 120, the brightness of the front side of the diffuser element 120 is basically the same as the brightness of the side side of the diffuser element 120.

[0170] In some embodiments, the width of the diffusion element 120 is 15 mm to 20 mm. Preferably, the width of the diffusion element 120 is 17 mm.
[0171] The width of the intrusion element 110 is adjusted according to the width of the diffusion element 120. Generally, it is sufficient to ensure that the brightness of the front side of the diffusion element 120 is basically the same as the brightness of the side side of the diffusion element 120, and that the brightness of the intrusion element 110 is at least equal to the brightness of the sidewall of the diffusion element 120.
[0172] The through slot element 130 is formed on the rear end face of the intrusion element 110.
[0173] The through-slot element 130 is approximately located at the center of the rear end face of the intrusion element 110. Specifically, there is a gap between the left end face (right end face, top end face, and bottom end face) of the through-slot element 130 and the left end face (right end face, top end face, and bottom end face) of the intrusion element 110. That is, the through-slot element 130 is disposed only through the rear end face of the intrusion element 110.

[0177] Furthermore, the lampshade component 100 also includes a light-transmitting coating element. The light-transmitting coating element covers the surface of the lampshade component 100.
[0178] Specifically, the light-transmitting coating element covers the surface of the intrusion element 110 and the surface of the diffusion element 120.
[0179] In some of these embodiments, the thickness of the light-transmitting coating element is 20–30 μm.

[0181] In some of these embodiments, the light-transmitting coating element is formed using a vacuum electroplating process.
[0182] In this invention, by utilizing a light-transmitting coating element, the lampshade component 100 can transmit light without the need for additional structural features such as "holes" or "slits." Furthermore, in the off state, due to the presence of the light-transmitting coating element, the lampshade component 100 exhibits a metallic decorative effect, enhancing its overall aesthetics and sophistication.
[0183] In some of these embodiments, the light-transmitting coating element includes, but is not limited to, a PVD coating.
[0184] like Figure 9 As shown, the light-emitting component 300 includes at least one first light-emitting element 310, at least one second light-emitting element 320, and at least one third light-emitting element 330. The first light-emitting element 310 is disposed upstream of the inner lens component 200 and is used to emit a first light source parallel to the light-emitting surface and a second light source intersecting the light-emitting surface; the second light-emitting element 320 is disposed upstream of the inner lens component 200 and is used to emit the first light source parallel to the light-emitting surface; the third light-emitting element 330 is disposed upstream of the inner lens component 200 and is used to emit the second light source intersecting the light-emitting surface.

[0191] 5) First light-emitting element 310, second light-emitting element 320 and third light-emitting element 330.
[0192] That is, through the above combination, the light-emitting component 300 can emit a first light source parallel to the light-emitting surface and a second light source intersecting with the light-emitting surface.
[0193] Generally, the first light-emitting element 310, the second light-emitting element 320, and the third light-emitting element 330 are LEDs.
[0194] In some embodiments, there are multiple first light-emitting elements 310. These multiple first light-emitting elements 310 are distributed (e.g., arranged in an array).
[0195] In some embodiments, there are multiple second light-emitting elements 320. These multiple second light-emitting elements 320 are distributed (e.g., arranged in an array).
[0196] In some embodiments, there are multiple third light-emitting elements 330. These multiple third light-emitting elements 330 are distributed (e.g., arranged in an array).
[0197] In implementation methods 2) to 5), different light-emitting elements can be distributed according to actual needs, such as by regional distribution or alternating distribution.
[0198] Furthermore, the three-dimensional light-emitting structure also includes a housing component 400. The housing component 400 has an inner lens component 200 and a light-emitting component 300 inside, and is connected to the lampshade component 100. At least a portion of the lampshade component 100 protrudes from the housing component 400.
[0199] like Figure 10 As shown, the housing component 400 includes a housing element 410 and a mounting element 420. The housing element 410 has an inner lens component 200 and a light-emitting component 300 disposed inside it; the mounting element 420 is disposed through the housing element 410 and is used for the lampshade component 100 to pass through so that at least a portion of the lampshade component 100 protrudes from the housing element 410.
[0200] Specifically, the housing element 410 is provided with a light mixing element 210, a first light-emitting element 310, a second light-emitting element 320, and a third light-emitting element 330; the mounting element 420 is used for the lampshade component 100 to pass through so that at least a portion of the lampshade component 100 protrudes from the housing element 410.
[0201] Generally, the housing element 410 has a front end face, a rear end face, a left end face, a right end face, a top end face, and a bottom end face. The front end face can be flat, curved, or uneven; the rear end face is generally flat; the left end face can be flat, curved, or uneven; the right end face can be flat, curved, or uneven; the top end face can be flat, curved, or uneven; and the bottom end face can be flat, curved, or uneven.
[0202] In addition, each end face of the housing element 410 can be a continuous surface or a discontinuous surface (such as a stepped surface).
[0203] There is an angle between the left end face (right end face) and the front end face, which can be any one of acute angle, right angle, or obtuse angle.
[0204] There is an included angle between the left end face (right end face) and the rear end face. This included angle can be any one of acute angle, right angle, or obtuse angle.
[0205] Generally, the left and right end faces are symmetrical about the front end face.
[0206] The assembly process of the housing component 410 and the lampshade component 100 is a conventional technique in the field, such as plugging and bonding, and will not be described in detail here.
[0207] In some of these embodiments, housing element 410 includes, but is not limited to, housing.
[0208] Mounting element 420 is provided on the front end face of housing element 410. Generally, lampshade component 100 and mounting element 420 are manufactured by conventional machining processes, such as integral molding, stamping, cutting, etc.
[0209] Mounting element 420 is located approximately at the center of the front end face of housing element 410. Specifically, there is a gap between the left end face (right end face, top end face, bottom end face) of mounting element 420 and the left end face (right end face, top end face, bottom end face) of housing element 410.
[0210] In some of these embodiments, the mounting element 420 is a mounting slot.
[0211] The method of using this utility model is as follows:
[0212] When the light-emitting component 300 (first light-emitting element 310, second light-emitting element 320, and third light-emitting element 330) is turned on, the first light source and the second light source emitted by the light-emitting component 300 enter the light mixing element 210. After the light mixing element 210 completes the light mixing, the light is reflected by the reflective element 220 through several concave teeth 231 and then enters the lampshade component 100. After the light source is diffused, it is emitted outward from the side wall and end of the lampshade component 100, so that the lampshade component 100 presents a uniform three-dimensional light-emitting state.
[0213] When the light-emitting components 300 (first light-emitting element 310, second light-emitting element 320, and third light-emitting element 330) are turned off, the light-transmitting coated element presents a metallic effect, forming an overall shape with the surrounding decorative parts.
[0214] The technical effects of this utility model are as follows:
[0215] 1) By combining the inner lens component and the lampshade component, three-dimensional light emission is achieved, which is no longer the traditional one-dimensional dot matrix light or two-dimensional line light;
[0216] 2) The lampshade components do not have traditional perforated structures such as "partial openings" or "slit openings," reducing the sense of disjointedness;
[0217] 3) When the lights are off, the lampshade component uses a PVD coating to form an integrated shape with the surrounding decorative parts, enhancing the sense of unity.
[0218] Example 3
[0219] This embodiment relates to the three-dimensional luminous grille of this utility model and an automobile.
[0220] A three-dimensional light-emitting grid includes a plurality of inner lens components 200 as described in Embodiment 1 or a plurality of three-dimensional light-emitting structures as described in Embodiment 2.
[0221] The three-dimensional luminous grid of this utility model includes the following implementation methods:
[0222] 1) Several three-dimensional light-emitting structures are arranged in parallel to each other;
[0223] 2) Some three-dimensional light-emitting structures are arranged in parallel with each other, and other three-dimensional light-emitting structures are arranged in parallel with each other. The two three-dimensional light-emitting structures are arranged to intersect, such as two three-dimensional light-emitting structures being arranged perpendicularly.
[0224] 3) Several three-dimensional light-emitting structures form a specific shape, for example, multiple three-dimensional light-emitting structures are connected end to end to form a ring structure, or multiple three-dimensional light-emitting structures are arranged radially, etc.
[0225] Furthermore, the aforementioned inner lens component 200, three-dimensional light-emitting structure, and three-dimensional light-emitting grille can be applied to automobiles.
[0226] Furthermore, in automobiles, the inner lens component 200 of Embodiment 1 and the stereoscopic light-emitting structure described in Embodiment 2 can also be applied to the cabin of the automobile as ambient lighting.
[0227] Example 4
[0228] This embodiment relates to a specific implementation of the present invention.
[0229] This embodiment is a specific implementation of the present invention.
[0230] In this embodiment, the three-dimensional light-emitting grid includes an LED light source group (equivalent to the light-emitting component 300 in Embodiment 1), an inner lens (equivalent to the inner lens component 200 in Embodiment 1), a housing (equivalent to the outer shell component 400 in Embodiment 1), and an outer lampshade (equivalent to the lampshade component 100 in Embodiment 1). The LED light source group is composed of multiple LEDs (equivalent to the first light-emitting element 310, the second light-emitting element 320, and the third light-emitting element 330 in Embodiment 1); the inner lens is a PMMA lens; and the outer lampshade is made of diffuser material PC.
[0231] The light-emitting principle of this embodiment is as follows:
[0232] The LED light source group includes a light source that enters the inner lens along the normal direction of the light-emitting surface (equivalent to the first light source in Embodiment 1) and a light source that is at a certain angle to the normal direction of the light-emitting surface (equivalent to the second light source in Embodiment 1).
[0233] The light source that enters the inner lens along the normal of the light-emitting surface passes directly through the inner lens and enters the outer lamp cover, forming a positive optical effect;
[0234] When a light source with a certain angle to the normal of the light-emitting surface illuminates the "optical pattern" area of the inner lens (equivalent to the "optical pattern element 230" in Embodiment 1), reflected light is generated in this area. The reflected light passes through the inner lens and illuminates the side of the outer lampshade from both sides of the inner lens. After the light is uniformly distributed by the outer lampshade, a lateral optical effect is formed.
[0235] The surface of the outer lampshade is coated with a PVD layer using a vacuum electroplating process (equivalent to the light-transmitting coating element in Example 1). The PVD coating thickness is 20–30 μm, and the PVD coating has a light transmittance of 10–15%. Using this design, the product's surface does not require additional "cutouts" or "slits" for light transmission. When the product is in the off state, the outer lampshade exhibits a metallic effect due to the PVD coating, serving a decorative purpose without diminishing the product's refined appearance.
[0236] Regarding the "optical pattern" of the inner lens, it consists of equilateral triangular concave teeth (equivalent to concave teeth 231 in Example 1), the depth of which varies along the direction of light transmission. Within the distance from the starting point to the ending point of the optical pattern, the depth varies as follows: the depth in the 0%–25% region of the overall distance transitions from 0.2 mm to 0.18 mm; the depth in the 25%–50% region of the overall distance transitions from 0.18 mm to 0.14 mm; and the depth in the 50%–100% region of the overall distance transitions from 0.14 mm to 0.11 mm.
[0237] The fit between the inner lens and the outer lamp cover is as follows:
[0238] The inner lens includes a light mixing area (equivalent to the light mixing element 210 in Embodiment 1) and a reflection area (equivalent to the reflection element 220 in Embodiment 1), and the outer lamp cover includes an intrusion area (equivalent to the intrusion element 110 in Embodiment 1) and a diffusion area (equivalent to the diffusion element 120 in Embodiment 1).
[0239] The light source first needs to complete the mixing within a mixing zone of at least 12mm width to ensure high dispersion of the light source when it enters the reflection area, thereby avoiding poor brightness uniformity on the sidewalls. (A mixing zone width of less than 12mm can easily lead to insufficient mixing and uneven brightness on the sidewalls; a mixing zone width greater than 12mm will increase unnecessary product weight and light source loss.)
[0240] The width of the diffusion zone is 17mm. This width is adjusted based on simulation results. If the width is too large, the brightness at the end furthest from the light source will be too low, and if the width is too small, the brightness of the sidewalls will be much lower than that of the forward viewing area, affecting the overall effect of the product.
[0241] The width of the intrusion zone is designed flexibly, mainly adjusted according to the width of the diffusion zone. The overall idea is: first, to ensure the brightness and consistency of the front and sides of the diffusion zone; second, to ensure that the brightness of the intrusion zone can reach the brightness of the sidewall of the diffusion zone. This goal is achieved by adjusting the optical pattern of the reflection zone.
[0242] The depth of the intrusion zone is 6mm. Within the intrusion zone, the distance between the inner lens and the lampshade is 0.3mm. The smaller this distance, the better, to ensure no dark areas. However, a distance that is too small may lead to low manufacturing yield and assembly problems.
[0243] The three-dimensional light-emitting grid of this embodiment was simulated using Speos optical simulation software. The LED light source was a single-channel Osram "D6RTB-SKG-Blue_5M_Rays_SPEOS". The normal brightness was approximately 380 nits, and the side brightness was approximately 250 nits.
[0244] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
