[0030] Please refer to Figures 1 to 8 , the light-emitting structure, the front-end light-emitting module and the vehicle provided by the utility model will be described. The light-emitting structure comprises a lamp panel 1, an inner lens panel 2 and a light-blocking support 3 arranged in sequence from back to front. The front side wall of the lamp panel 1 is provided with a light source 11. The inner lens panel 2 is provided with a light dispersing tooth 21 for dispersing light rays. The light dispersing tooth 21 is located on the side of the inner lens panel 2 adjacent to the lamp panel 1. The light-blocking support 3 is provided with a light-emitting hole 33 for emitting light rays outward.

[0031] Compared with the prior art, the light-emitting structure provided by the embodiment can not only disperse the light rays emitted by the light source 11 to form uniform light spots, but also adjust the propagation direction of the light rays so that the light rays are emitted from the light-emitting hole 33 of the light-blocking support 3, thereby realizing uniform illumination of the light rays, greatly improving the light leakage ratio of dark / bright areas, helping to improve the light efficiency and reduce glare, making the light rays brighter and softer, and improving the visual comfort of the driver and passengers.

[0032] In the embodiment, the light dispersing tooth 21 arranged on the rear side of the inner lens panel 2 refracts the light rays. The tooth angle and size of the light dispersing tooth 21 should be adjusted according to the emission angle and radiation area of the light rays, so that the light rays are scattered into uniform light spots and their propagation direction is changed, thereby greatly improving the light leakage ratio of dark / bright areas and effectively preventing the light leakage problem. The position of the light dispersing tooth 21 can be arranged according to the arrangement requirement of the light source 11. The light dispersing tooth 21 can be used to disperse the light rays and emit them to the specified area through the light-emitting hole 33.

[0033] Specifically, the diffusing teeth 21 of the inner lens plate 2 are sawtooth structures protruding towards the light source 11 side, for controlling the distribution of light, having the dual effects of forming light spots by scattering light and changing the direction of light propagation, which can reduce glare and improve haze. Compared with the traditional light uniformity plate, the setting of the inner lens plate 2 can increase the light transmittance by 20%, the brightness of the light source 11 is increased from the original 1400 nit to 1600-2000 nit, and the light leakage ratio is increased from the original 56:1 to 95:1, so that the uniformity of the light is good, avoiding the problem of black frame at the edge position of the traditional light emitting structure, under the condition of ensuring the same brightness level, the power consumption of the light source 11 is less than 0.07 watts, and the whole lamp power is less than 56 watts, which is much smaller than the power consumption of 80 watts of the traditional whole lamp, and can save 30% of energy consumption.

[0034] In some possible implementation manners, the light shielding support 3 adopts the structure as shown in Figure 2 、 Figure 4 、 Figure 7 and Figure 8 . Referring to Figure 2 、 Figure 4 、 Figure 7 and Figure 8 , the light shielding support 3 includes a front plate body 31 and a light shielding strip plate 32, the light emitting hole 33 is arranged through the front plate body 31, and the light shielding strip plate 32 is connected to the rear side of the front plate body 31 and is arranged perpendicularly to the front plate body 31. The light shielding strip plate 32 is provided with a plurality of light shielding spaces 34, and the light emitting hole 33 and the light shielding space 34 are arranged one by one.

[0035] In the embodiment, the light shielding support 3 adopts the combination of the front plate body 31 and the light shielding strip plate 32, and the light shielding strip plate 32 is connected to the rear side of the front plate body 31 and is arranged perpendicularly to the front plate body 31. The light shielding strip plate 32 can be arranged in a transverse, longitudinal or oblique manner, and can be enclosed into a light shielding space 34 corresponding to a single light source 11, so that the light emitted by the single light source 11 can be scattered out through the corresponding light shielding space 34 and the light emitting hole 33, having good light shielding efficiency, ensuring the separate scattering of the light of the single light source 11, ensuring the uniformity of light dispersion, and reducing the light leakage problem of dark / bright areas.

[0036] In some possible implementation manners, the inner lens plate 2 adopts the structure as shown in Figure 2 、 Figure 4 and Figure 6 . Referring to Figure 2 、 Figure 4 and Figure 6The inner lens plate 2 is provided with a plug-in slot 22 opening forward, and the light-blocking strip plate 32 is plugged into the plug-in slot 22. The plug-in slot 22 and the extension of the light-blocking strip plate 32 are consistent in arrangement, which ensures the stability of the relative position between the light-blocking strip plate 32 and the lamp plate 1, and further makes the light-blocking space 34 effectively correspond to the light of the single light source 11, thereby ensuring stable light emission effect. The plug-in mode can effectively seal the light-blocking space 34, thereby avoiding light leakage and waste, and enabling the light to be fully emitted outward through the light emission hole 33.

[0037] Specifically, the thickness of the light-blocking strip plate 32 at the end close to the lamp plate 1 is less than the thickness at the end away from the lamp plate 1, and the internal width of the plug-in slot 22 is less than the width at the opening. The change trend of the above-mentioned thickness and width facilitates the guiding effect of the light-blocking strip plate 32 when it is inserted into the plug-in slot 22, improves the plug-in efficiency, and ensures the plug-in precision.

[0038] In some possible implementation manners, the inner lens plate 2 adopts the structure as shown in Figure 4 and Figure 6 . Referring to Figure 4 and Figure 6 , the inner lens plate 2 is arranged outwardly protruding from the light-blocking support 3, and the front end surface of the inner lens plate 2 is embedded with a sealing ring 4, which is located at the outer periphery of the light-blocking support 3 and used to abut against the rear side wall of the light-transmitting skin 5.

[0039] In the embodiment, the front side wall of the inner lens plate 2 is embedded with the sealing ring 4, the front end surface of the inner lens plate 2 is provided with a circumferentially extending embedding slot, the sealing ring 4 is installed in the embedding slot and is arranged outwardly protruding from the front end surface of the inner lens plate 2, which can form an abutting and sealing effect with the rear side wall of the light-transmitting skin 5, thereby avoiding the loss of the light emitted by the inner lens plate 2 and outwardly diverging.

[0040] Further, the sealing ring 4 extends along the circumference and is closed in a ring structure, which has good sealing effect and can effectively prevent external impurities and mosquitoes from entering the light-blocking support 3 to affect the smooth emission of light, thereby ensuring good light transmittance.

[0041] Based on the same inventive concept, the embodiment of the present application further provides a front-end light-emitting module. The front-end light-emitting module comprises, from rear to front, a light-transmitting skin 5, a light-emitting structure and a lamp shell 6 in sequence. The light-transmitting skin 5 comprises a light-transmitting base material and a light-blocking coating layer coated on the light-transmitting base material. The light-blocking coating layer is provided with a light-transmitting hole corresponding to the light emission hole 33 in front and back. The light-transmitting base material is provided with a light-transmitting region 51 corresponding to the light-transmitting hole. The lamp shell 6 is connected with the light-emitting structure. The light-emitting module has simple structure, convenient installation, good light transmittance, and can improve light efficiency and reduce glare, so that the light is brighter and softer, thereby improving the visual comfort of the driver and passenger.

[0042] In this embodiment, the lamp housing 6 is connected to the rear side of the light-emitting structure and can be connected to the vehicle body structure through the lamp housing 6. Light emitted by the light-emitting structure can be emitted outward through the light-transmitting skin 5.

The light-isolating coating layer is located on the rear side wall of the light-transmitting substrate, that is, on the side close to the light-emitting structure. The light-isolating coating layer is provided with light-transmitting holes corresponding to the front and rear of the light-emitting hole 33 for light emission. The area on the light-transmitting substrate where the light-isolating coating layer is not provided forms a light-transmitting area 51 (that is, the area of ​​the light-transmitting substrate corresponding to the light-transmitting holes) so that light can be emitted smoothly from the light-transmitting area 51.

[0044] The translucent base material is made of translucent PP-M10, which offers high light transmittance and excellent energy absorption. PP's high flexural modulus and excellent toughness allow it to effectively absorb collision energy in low-speed collisions, protecting pedestrians.

[0047] In this embodiment, the light-isolating strip 32 of the light-isolating bracket 3 can be inserted into the insertion slot 22 of the inner lens panel 2, effectively defining the vertical and horizontal positions of the light-isolating bracket 3 and the inner lens panel 2. A connector extends through the light-isolating bracket 3, the inner lens panel 2, and the light panel 1, connecting it to the rear lamp housing 6. This further locks the front-to-back position of the light-isolating bracket 3 and the inner lens panel 2, and connects the light-isolating bracket 3, the inner lens panel 2, the light panel 1, and the lamp housing 6 as a whole, ensuring the reliability of the structural connection.

[0048] In one possible implementation, see Figure 4 、Figure 5 and Figure 7 The lamp shell 6 is provided with a forward protruding connecting boss 61, the connecting boss 61 is provided with a threaded sleeve 62 for threadedly connecting the connecting piece, and the light shielding support 3 is provided with a countersunk hole 35 for the connecting piece to penetrate.

[0049] In the embodiment, the end head part of the connecting piece is effectively accommodated by arranging the countersunk hole 35 on the light shielding support 3, so that the connecting piece does not protrude forward from the front end surface of the light shielding support 3, and the flatness of the front end surface of the light shielding support 3 is ensured. The connecting boss 61 protruding forward can be arranged on the lamp shell 6, and the connecting boss 61 is provided with a forward opening threaded hole. The connecting piece is a threaded connecting piece, which can be threadedly matched with the threaded hole, and the light shielding support 3, the inner lens plate 2, the lamp plate 1 and the lamp shell 6 can be effectively connected.
