Illustratively, with further reference to FIG. 9, FIG. 9 shows a side view of the first trim panel, the second trim panel, and the thick-walled light guide panel in an embodiment of the utility model. The first decorative plate 200 includes a first clip 21 and a first bezel 22. The first wreath 22 is integrally coupled to one end of the first clip portion 21, and the first wreath 22 is inclined with respect to the first clip portion 21. The second decorative plate 300 includes a second clip 31 and a second bezel 32. The second bezel 32 is integrally coupled to one end of the second clip portion 31, and the second bezel 32 is inclined corresponding to the second clip portion 31. And the first and second clip portions 21 and 31 are arranged in parallel or nearly in parallel so that an embedding groove 81 accommodating the thick-walled light guide plate 400 is formed between the first and second clip portions 21 and 31.

The decorative pattern is provided on the first decorative ring 22 and the second decorative ring 32, the first decorative ring 22 and the second decorative ring 32 extend from one end of the first clamping part 21 or the second clamping part 31 in a direction away from the first clamping part 21 and gradually deviate from the first clamping part 21 and the second clamping part 31, and a conical decorative groove 82 is formed between the first decorative ring 22 and the second decorative ring 32. The thick-walled light guide plate 400 is mounted in the fitting groove 81, and one end of the thick-walled light guide plate 400 provided with the exit surface 41 extends into the decorative groove 82.

During use, it is found that: the reflective surface 44 is a slope or an arc surface, so that when the first clip portion 21 is pressed on the reflective surface 44, a gap is easily generated between the first clip portion 21 and the reflective surface 44, and meanwhile, the bead plate 500 and the first decorative plate 200 are disposed on the same side of the thick-wall light guide plate 400, which results in that the bead plate 500 leaks from the gap between the first clip portion 21 and the reflective surface 44, so that the front position lamp generates a problem of light leakage. In addition, since a gap exists between the first clip portion 21 and the reflecting surface 44, the structure of the inner bead plate 500 can be observed from a specific angle.

In this embodiment, the thick-walled light guide plate 400 is provided with a raised stopper 43. Specifically, the stopper 43 is formed on the reflecting surface 44. The stopper 43 is located between the bead plate 500 and the first decorative plate 200, such that the stopper 43 blocks the gap between the first clip portion 21 and the reflective surface 44, i.e., the stopper 43 is located on the light path where the light leaks from the gap, and the stopper 43 blocks the light leaking from the gap to avoid the problem of light leakage. At the same time, the stop 43 also blocks the view from the outside of the interior of the headlight structure along the gap.

Further, the second decorative plate 300 is fixedly coupled to the bracket 600. Specifically, as shown in fig. 6, the bracket 600 further includes a joint 62, one end of the second clip 31 is connected to the second decorative ring 32, and the other end of the second clip 31 is provided with a connecting portion 33 that is cooperatively connected to the joint 62.

During the assembly, the first and second decorative panels 200 and 300 are assembled in sequence. Specifically, the first decorative plate 200 is mounted on the bracket 600 before the thick-wall light guide plate 400, and the second decorative plate 300 is mounted after the thick-wall light guide plate 400 is mounted, so that damage caused by sliding of the thick-wall light guide plate 400 between the first decorative plate 200 and the second decorative plate 300 is avoided, and the thick-wall light guide plate 400 can be prevented from being scratched by the first decorative plate 200 and the second decorative plate 300 in the assembly process.

It is understood that the positioning posts that are mutually positioned and matched with the parts of the front position lamp structure can be the same positioning post or different positioning posts.

In some embodiments of the present utility model, the thick-walled light guide plate 400 is injection molded of a transparent PC material, so that the thick-walled light guide plate 400 has good light transmittance and high luminous efficiency. The light emitted by the bead plate 500 is directly emitted through the optical mode of the thick-wall light guide plate 400, so that the light is more uniform, and the lighting effect is more transparent. The light is uniform from the light transmission opening 111 under all angles, and the arrangement space and the interval of the whole lamp are smaller, so that the internal space requirements of different vehicle types can be met.

Further, the exit surface 41 of the thick-walled light guide plate 400 is provided with an optical pattern layer, ensuring uniformity after lighting. Meanwhile, the side surface of the thick-wall light guide plate 400 is provided with an optical skin layer, and the reflective layer 44 is also provided as an optical skin layer, which can effectively shield the internal LEDs and other structures. Specifically, the optical skin layer is provided at least on the side surface of the thick-walled light guide plate 400 to which the first decorative plate 200 and the second decorative plate 300 are attached. The optical dermatoglyph structure on the surface of the thick-wall light guide also plays a role in shielding the lamp beads 52, and after the whole lamp is lighted, the lamp beads 52 and other structures in the whole lamp cannot be seen, so that the attractiveness of the whole lamp in the lighted state is ensured.

It should be noted that the optical skin layer is not disposed on the incident surface 42, so that the light can smoothly pass through the incident surface 42, and the loss caused by the light reflected at the incident surface 42 is reduced, so as to improve the luminous efficiency, and more light can be projected from the emitting surface 41, so as to improve the brightness of the whole lamp after being lighted.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

The above examples illustrate only a few embodiments of the utility model, which are described in detail and are not to be construed as limiting the scope of the claims. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the utility model, which are all within the scope of the utility model. Accordingly, the scope of protection of the present utility model is to be determined by the appended claims.
