Detailed Implementation

[0018] The present invention will be further described in detail below with reference to the accompanying drawings.

[0019] Example: A combined automotive luminous grille, such as Figure 1 and Figure 2 As shown, it includes a light-emitting substrate 1, a light-guiding substrate 2, a light-transmitting substrate 3, and a grid plate 4 arranged in sequence. The light-emitting substrate 1, the light-guiding substrate 2, the light-transmitting substrate 3, and the grid plate 4 are detachably connected. The installer and user can achieve stable assembly and use of the light-emitting grid by stably fastening the substrates together, which facilitates the flexible assembly and disassembly of the entire light-emitting grid.

[0020] A light-emitting module is provided on the light-emitting substrate 1. The light-emitting substrate 1 has a driving groove 22 for mounting and fitting the light-emitting module. The light-emitting module, which is fitted into the driving groove 22, includes a circuit board 5 and several LED beads 6. The LED beads 6 are integrated and mounted on the circuit board 5, allowing vehicle users to control the linkage lighting of each LED bead 6 in the circuit board 5 by inputting electrical signals from the vehicle control system, thereby achieving a customized dynamic control effect. Due to the programmability of the lighting control effect among the LED beads 6, in order to fully meet the actual dynamic lighting effect, the combination of the light guide substrate 2 and the light-transmitting substrate 3 effectively ensures the sufficient single-core lighting of the individual LED beads 6, thereby meeting the needs of vehicle users to achieve a dot-matrix dynamic lighting effect.

[0021] The light-emitting substrate 1 is provided with snap-fit ​​grooves 7 around its perimeter, and the light guide substrate 2 is provided with snap-fit ​​ring edges 8 around its perimeter that cooperate with the snap-fit ​​grooves 7. Users only need to snap the light guide substrate 2 onto the light-emitting substrate 1 to achieve stable assembly. Several light guide holes 9 corresponding to the lamp beads 6 are provided in the middle of the light guide substrate 2. When the user covers the light-emitting substrate 1 with the light guide substrate 2, the light emitted by the individual lamp beads 6 is ensured to pass through the designated light guide holes 9. A light guide sleeve 10 is provided inside the light guide hole 9, and a light guide groove 11 is provided in the middle of the light guide sleeve 10. The light emitted by the lamp beads 6 is led out through the light guide groove 11. At the same time, the diameter of the end of the light guide sleeve 10 near the light-transmitting substrate 3 is smaller than the diameter of the end near the light-emitting substrate 1. The optimized structure layout of wide inlet and narrow outlet further improves the focusing and diffusion effect of the individual lamp beads 6. Considering that users need to manually adjust the light during actual use, and to ensure full cooperation between the light guide sleeve 10 and the lamp bead 6, and to flexibly correct the light dispersion of the light guide sleeve 10, an adjustment thread is provided on the inner wall of the light guide hole 9. The light guide sleeve 10 and the light guide hole 9 are connected by a spiral rotation, which facilitates the manual adjustment action of the user.

[0022] Multiple mounting claws 12 are provided around the light-transmitting substrate 3 for mounting and fixing the overall light-emitting grille to the vehicle body bracket. The light-emitting substrate 1 and the light-guiding substrate 2 are snapped together and embedded in the light-transmitting substrate 3. The side wall of the light-emitting substrate 1 is provided with insertion slots 19 that engage with the mounting claws 12, ensuring a stable assembly relationship. At the same time, the light-transmitting substrate 3 is provided with several light-transmitting holes 13 aligned with the light-guiding sleeve 10. A condensing lens 14 is provided in the light-transmitting hole 13. The condensing lens 14 is located in the middle of the light-transmitting hole 13. The light transmitted from the light-guiding substrate 2 on one side is emitted through the condensing lens 14, and the condensing lens 14 in the middle of the light-transmitting hole 13 ensures the independent illumination effect of each light and reduces the mutual interference between the individual light rays.

[0023] The side wall of the light-transmitting substrate 3 is also provided with a fastening bolt 20 that is movably connected. The light-emitting substrate 1 is provided with a fastening hole 21 that is aligned with the fastening hole 21. By locking the fastening bolt 20 with the fastening hole 21, the movement of the light-emitting substrate 1 and the light guide substrate 2 is restricted, thereby improving the overall structural stability of the light-emitting grid.

[0024] The grille plate 4 is movably engaged with the side of the light guide substrate 2 away from the light guide substrate 2. Elastic locking blocks 15 are provided around the grille plate 4, and the light guide substrate 2 has mounting slots 16 that elastically engage with the elastic locking blocks 15. The installer presses and fastens the grille plate 4 into the mounting slots 16. The side wall of the grille plate 4 also has positioning holes 23 that cooperate with fastening bolts 20, further improving the reliability and accuracy of the grille plate 4 assembly. A grille mesh block 17 is provided in the center of the grille plate 4. The grille mesh block 17 has light-emitting grid grooves 18 that cooperate with the light-transmitting holes 13, ensuring that the light emitted from each light-transmitting hole 13 is uniformly emitted from the contour of the fixed light-emitting grid groove 18, efficiently presenting the preset light-emitting grid light effect, and reducing the light interference between multiple light-transmitting holes 13, improving the visibility and uniformity of the light-emitting grid light. Simultaneously, the externally detachable grille plate 4, as the outermost layer of the light-emitting grid, effectively protects the light-emitting substrate 1, etc., and is easily disassembled and replaced as a vulnerable part.

[0025] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
