[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figure 1 and Figure 2 as shown, which includes an interior exterior panel 1, a light - transmissive film 2 with a pattern, a light - homogenizing plate 3, a light - concentrating plate 4, and a circuit board 5 with lamp beads;

[0023] The interior exterior panel 1 is a light-transmitting structure, that is, a transparent part, with a diamond-cut surface structure provided on the surface or inside. The light emitted by the ambient light beads hits the surface vertically and diffuses out to form a crystal light-emitting effect. The surface is composed of scratch-resistant materials or made of spray-free materials through two-color injection molding process. Inside, a very thin vacuum plating layer is obtained through vacuum plating process, with uniform coating and consistent color. The color and luster of the plating layer affect the overall appearance of the product. The vacuum plating layer affects the electromagnetic compatibility performance of the structure of this interior crystal light-emitting part, and meets the electromagnetic compatibility performance while ensuring the appearance.

[0024] The light-transmitting film 2 can be customized with texture patterns. When the total assembly light-emitting structure is not lit, the pattern is hardly noticeable. After being lit, the pattern effect is obvious. The pattern is composed of multiple colors.

[0025] The light homogenizing plate 3 is made of optical materials and has a diffusing effect on the optical effect of the ambient light beads, making the lit optical effect more uniform and consistent visually.

[0026] The light concentrating plate 4 is made of optical materials and provides a separate space for each ambient light bead, avoiding color interference between different color changes of the ambient light beads and optimizing the visual effect.

[0027] The interior exterior panel 1, the light-transmitting film 2, the light homogenizing plate 3, the light concentrating plate 4 and the circuit board 5 with beads are snap-connected in sequence from outside to inside. The interior exterior panel 1 and the light concentrating plate 4 are welded and strengthened in the lateral or vertical direction.

[0028] During installation, first, the light concentrating plate 4 and the light homogenizing plate 3 are snap-connected to each other. The snap connection interference amount between the two is at least 0.2 mm, and the overlapping amount is 0.6 - 0.8 mm. The light concentrating plate 4 and the light homogenizing plate 3 are snap-connected to each other. The snap connection interference amount between the two is at least 0.2 mm, and the overlapping amount is 0.6 - 0.8 mm. The light-transmitting film 2 adopts a limiting structure and is fixed on the sub-assembly formed by the light concentrating plate 4 and the light homogenizing plate 3 to form a secondary sub-assembly. The pre-fixed structures are distributed on the left, middle and right. There are openings on the limiting structure. The transverse dimension of the opening is between 5.3 and 6 mm, and the front-back dimension is about between 2.5 and 3 mm. The rear part of the opening is in close contact with the light concentrating plate 4 to ensure the position in the front-back direction. Specifically refer to Figure 2 and Figure 3 shown.

[0029] After the interior exterior panel 1 is snap-connected to the secondary sub-assembly, it is welded to form a tertiary sub-assembly, so that the butt joint between the interior exterior panel 1 and the light concentrating plate 4 forms a weld mark for fixed fitting. The welding direction can be vertical welding or lateral welding. The lateral welding direction is as Figure 4As shown. The welding is made by a specially customized welding tooling, and the welding method is laser welding. The laser energy is controlled to heat the surface of the crystal effect decorative part 1, and the surface heat diffuses to the internal condenser plate 4 through heat conduction. By controlling parameters such as the width, energy, peak power, and repetition frequency of the laser pulse, the crystal effect decorative part 1 and the condenser plate 4 are locally melted to form specific welding marks, so that the two are fixed together. The welding positions are arranged in sections according to the strength requirements, and the welding strength should meet the relevant definitions.

[0030] In addition, continue to refer to Figure 2 and Figure 3 As shown, a bottom cover plate 7 is fixed on one side of the circuit board 5. The bottom cover plate 7 and the circuit board 5 are jointly fixed on the three-stage sub-assembly by screws 6 to form a four-stage sub-assembly. It also includes a microcontroller hardware module 8. The microcontroller hardware module 8 is fixed to the four-stage sub-assembly and is electrically connected to the circuit board 5 through a wire harness and a plug connector. The connector and the microcontroller module are the power supply, signal connection, and control devices for the interior trim parts, providing the energy source and signal source for the lighting of the atmosphere lamp. The operation information of the customer on the large-screen host is transmitted to the atmosphere lamp beads through this device, thereby controlling the brightness change and color change of the lamp beads.

[0031] In the actual use of the vehicle, it can be a single interior crystal effect light-emitting part structure or a combination of multiple structures.

[0032] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
