With the rapid development of the automotive industry, existing lighting control systems are no longer able to meet the demands of automotive design and production, necessitating improvements and adjustments. Existing headlights suffer from issues such as insufficient space and uneven lighting on thick-walled components.

[0003] Therefore, how to improve the uniformity of lighting of thick-walled parts has become a technical problem that needs to be solved urgently by those skilled in the art. Utility Model Content

[0004] In view of this, an object of the present invention is to provide a thick-walled component to improve the uniformity of lighting of the thick-walled component.

[0005] Another core of the present invention is to disclose a vehicle lamp comprising the above-mentioned thick-walled member.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A thick-walled component, comprising: a light incident surface, a first reflecting surface, a second reflecting surface, a third reflecting surface, and a light emitting surface; a light source is disposed opposite the light incident surface; light emitted by the light source is irradiated onto the first reflecting surface via the light incident surface, reflected onto the second reflecting surface via the first reflecting surface, reflected onto the third reflecting surface via the second reflecting surface, and emitted through the light emitting surface after being reflected onto the third reflecting surface;

[0008] The incident section is between the light incident surface and the first reflecting surface, and the first reflecting section is between the second reflecting surface and the third reflecting surface. The incident section and the first reflecting section are arranged in parallel with a gap provided between them.

[0009] Optionally, in the above-mentioned thick-walled member, the paths of the light in the incident section and the first reflecting section are in opposite directions.

[0026] In addition to the problems mentioned in the background technology, the existing technology also has the problem of insufficient space for vehicle lights.

[0027] The core of the utility model is to disclose a thick-walled component to improve the uniformity of lighting of the thick-walled component.

[0028] Another core of the present invention is to disclose a vehicle lamp comprising the above-mentioned thick-walled member.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] The structural diagram of the thick-walled part in the prior art is as follows Figure 1-Figure 3 As shown, Figure 1 The method shown is direct projection. The thick-walled component includes a light incident surface 10 and a light emitting surface 50 . Light emitted by a light source 60 enters through the light incident surface 10 and exits from the light emitting surface 50 . Figure 2 and Figure 3 Using side projection, Figure 2 The thick-walled part includes a light incident surface 10 , a first reflective surface 20 and a light emitting surface 50 . Light emitted by the light source 60 is incident through the light incident surface 10 , reflected by the first reflective surface 20 , and then emitted from the light emitting surface 50 . Figure 3 The thick-walled part shown includes a light incident surface 10 , a first reflective surface 20 , a second reflective surface 30 and a light emitting surface 50 . Light emitted by a light source 60 is incident through the light incident surface 10 , reflected by the first reflective surface 20 and the second reflective surface 30 , and then emitted from the light emitting surface 50 .

[0031] The present invention discloses a thick-walled part. Figure 4 As shown, it includes a light incident surface 10 , a first reflection surface 20 , a second reflection surface 30 , a third reflection surface 40 and a light emitting surface 50 .

[0032] Specifically, a light source 60 is disposed directly opposite the light incident surface 10. Light source 60 is preferably an LED particle, and the number of LED particles can be one or more. As shown in the optical path diagram (path indicated by arrows in the figure), light emitted by light source 60 passes through the light incident surface 10 and is irradiated by the first reflective surface 20. This light is then reflected by the first reflective surface 20 to the second reflective surface 30, and then by the second reflective surface 30 to the third reflective surface 40. After being reflected by the third reflective surface 40, it is emitted through the light emitting surface 50. Furthermore, the first reflective surface 20, the second reflective surface 30, and the third reflective surface 40 may be provided with patterns.

[0033] The incident section 1 is located between the light incident surface 10 and the first reflective surface 20, and the first reflective section 2 is located between the second reflective surface 30 and the third reflective surface 40. The incident section 1 and the first reflective section 2 are arranged in parallel with a gap between them. The specific size of the gap can be determined based on actual conditions. This approach can reduce the volume of thick-walled components, save space within the headlight, and improve space utilization.

[0034] In the thick-walled component disclosed in the embodiment of the present invention, light emitted by the light source 60 undergoes multiple reflections before exiting from the light-emitting surface 50, resulting in uniform light and improved lighting uniformity of the thick-walled component. A gap is provided between the incident section 1 and the first reflective section 2, which reduces the volume of the thick-walled component, saving space within the headlight and improving space utilization.

[0035] In some specific embodiments, Figure 4 As shown in the figure, the paths of light in the incident section 1 and the first reflection section 2 are opposite. As shown in the figure, the light path direction in the incident section 1 is from top to bottom, and the light path direction in the first reflection section 2 is from bottom to top. This method can shorten the length of thick-walled parts.

[0036] In other specific embodiments, the light paths in the incident segment 1 and the first reflective segment 2 are in the same direction, that is, the light paths in both the incident segment 1 and the first reflective segment 2 are from top to bottom, i.e., the first reflective segment 2 continues to extend along the length of the incident segment 1. This approach requires sufficient space within the vehicle lamp. Preferably, the light paths in the incident segment 1 and the first reflective segment 2 are in opposite directions.

[0037] Furthermore, if Figure 4 As shown, a second reflecting section 3 is provided between the first reflecting surface 20 and the second reflecting surface 30, that is, the first reflecting surface 20 and the second reflecting surface 30 are not connected. Specifically, the incident section 1 and the first reflecting section 2 extend along the first direction, and the second reflecting section 3 extends along the second direction, and the first direction and the second direction are perpendicular. It should be noted that the first direction can refer to the length direction of the vehicle body or the width direction of the vehicle body, and correspondingly, the second direction refers to the width direction or the length direction of the vehicle body. This solution is suitable for scenarios where the space in the second direction of the headlight is small, but the space in the first direction is large. This solution can save space in the headlight and achieve uniform output light.

[0038] In some specific embodiments, the first reflective surface 20 and the second reflective surface 30 are connected and form a certain angle therebetween. Furthermore, the first reflective surface 20 and the second reflective surface 30 can be arranged vertically.

[0039] Furthermore, if Figure 4As shown, the light emitting section 4 is located between the third reflecting surface 40 and the light emitting surface 50. The light emitting section 4 is arranged parallel to the second reflecting section 3. The path of the light in the light emitting section 4 is the same as or opposite to the path in the second reflecting section 3. Preferably, the paths are the same, that is, the direction of the light path shown in the figure is from left to right.

[0040] In some specific embodiments, optical patterns are provided on the light incident surface 10 and / or the light emitting surface 50 .

[0041] In addition, the embodiment of the present utility model further discloses a vehicle lamp, comprising a light source 60 and the thick-walled member of the above embodiment, and therefore has all the technical effects of the above thick-walled member, which will not be described in detail.

[0042] It should be noted that the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same and similar parts between the various embodiments can be referenced to each other.

Therefore, features specified as "first" or "second" may explicitly or implicitly include one or more of such features.
