[0031] One of the cores of the utility model is to provide a thick-walled light-guiding structure, the structural design of which can reduce or avoid defects such as dark areas and bright spots at the joints of thick walls, and improve the optical continuity and uniformity of the joints of the thick-walled light-guiding structure.

[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0034] See also Figures 1 to 3 , Figure 1 A schematic structural diagram of a thick-walled light guide structure from a light-emitting side perspective provided in an embodiment of the utility model. Figure 2 for Figure 1 A partial enlarged schematic diagram of the light output side angle at point A in the middle. Figure 3 for Figure 1 A partially enlarged schematic diagram of the light incident side viewing angle at point A in the middle.
[0035] The embodiment of the utility model discloses a thick-wall light-guiding structure, which comprises a first thick-wall component 1 , a second thick-wall component 2 and a first light-emitting element 3 .
[0036] Among them, one end face of the first thick-walled component 1 is a first split surface, which obliquely intersects with the extension direction of the first thick-walled component 1, and the two sides of the first thick-walled component 1 in the extension direction are respectively the light incident side 101 and the light emitting side 102 of the first thick-walled component 1.
[0037] One end face of the second thick-walled component 2 is a second split surface, and the second split surface is obliquely intersected with the extension direction of the second thick-walled component 2. The two sides of the second thick-walled component 2 in the extension direction are respectively the light entrance side 201 and the light exit side 202 of the second thick-walled component 2. The light entrance side 101 of the first thick-walled component 1 and the light entrance side 201 of the second thick-walled component 2 are located on the same side of the thick-walled light-guiding structure. The light exit side 102 of the first thick-walled component 1 and the light exit side 202 of the second thick-walled component 2 are located on the same side of the thick-walled light-guiding structure. The first thick-walled component 1 and the second thick-walled component 2 are in contact and matched with each other through the first split surface and the second split surface, that is, a chamfered matching structure is formed between the first thick-walled component 1 and the second thick-walled component 2. The dimensions of the first thick-walled component 1 and the second thick-walled component 2 from the light entrance side to the light exit side may be the same or different.
[0038] The first thick-walled component 1 and the second thick-walled component 2 adopt a structure that is entirely transparent or partially transparent to ensure that the light emitted by the light-emitting element can be emitted through the first thick-walled component 1 and the second thick-walled component 2 .
[0039] like Figure 3 As shown, the first light-emitting element 3 is arranged on the light-incident side of the first thick-walled component 1, the extension direction of the first light-emitting element 3 is the same as the extension direction of the first thick-walled component 1, and one end of the first light-emitting element 3 passes through the plane where the first slit surface and the second slit surface are located.
[0040] Of course, it should be noted that Figure 1 As shown, a second light emitting element 4 is provided on the light incident side of the second thick-walled component 2 , and the extension direction of the second light emitting element 4 is the same as the extension direction of the second thick-walled component 2 .
[0041] Compared with the prior art, the thick-walled light-guiding structure provided in the embodiment of the utility model designs the joint between the first thick-walled component 1 and the second thick-walled component 2 so that the first thick-walled component 1 and the second thick-walled component 2 are in contact and matched through the first split surface and the second split surface, so that the first light-emitting element 3 can illuminate the joint between the first thick-walled component 1 and the second thick-walled component 2 at the same time. This structure can not only enable multiple thick-walled components to be spliced into continuously changing shapes, increase the diversity of thick-walled component splicing, and realize diversified shapes, but also avoid the generation of defects such as dark areas and bright spots at the joints of two thick-walled components, thereby improving the optical continuity and uniformity of the joints of the thick-walled light-guiding structure.
[0042] Please combine Figure 3 ,refer to Figures 4 to 6 , Figure 4 A schematic structural diagram of a thick-wall light guide structure provided by an embodiment of the present invention in which a first thick-wall component and a second thick-wall component are spliced together from a light-emitting side perspective. Figure 5 for Figure 4 A partial enlarged schematic diagram of the light-emitting side viewing angle at point B in the middle. Figure 6 for Figure 4 A partially enlarged schematic diagram of the light incident side viewing angle at point B in the middle.
[0043] In one embodiment of the utility model, the dimension of the second thick-walled component 2 along the direction from the light incident side 201 to the light emitting side 202 is greater than the dimension of the first thick-walled component 1 along the direction from the light incident side 101 to the light emitting side 102. In this case, the end of the first light-emitting element 3 will be interfered by the second thick-walled component 2, and the second thick-walled component 2 cannot be illuminated. To avoid this situation, an avoidance groove 204 for avoiding the end of the first light-emitting element 3 is provided at one end of the light incident side of the second thick-walled component 2 close to the first thick-walled component 1, such as Figure 6 As shown, the avoidance groove 204 can avoid the first light emitting element 3 , so that the first light emitting element 3 can smoothly extend from the first thick-walled component 1 to the second thick-walled component 2 , thereby illuminating the second thick-walled component 2 .
[0044] To further optimize the above technical solution, in an embodiment of the utility model, a plurality of light guide grooves 205 are arranged on the groove wall of the avoidance groove 204 extending from the light incident side 201 to the light emitting side 202 of the second thick-walled component 2. The light guide grooves 205 extend from the light incident side 201 to the light emitting side 202 of the second thick-walled component 2. The light guide grooves 205 can guide the light of the first light-emitting element 3 to avoid diffuse reflection of the light of the first light-emitting element 3 by the avoidance groove 204, thereby further improving the optical continuity and uniformity of the joint between the first thick-walled component 1 and the second thick-walled component 2.
[0045] Specifically, the cross-sectional shape of the light guide groove 205 includes but is not limited to a triangle, a trapezoid, a rectangle and a semicircle.
[0046] like Figure 7 As shown, in an embodiment of the utility model, the second thick-walled component 2 includes a first part 206 and a second part 207 which are connected in sequence along the extension direction. The size of the first part 206 along the direction from the light incident side 201 to the light emitting side 202 of the second thick-walled component 2 is smaller than the size of the second part 207 along the direction from the light incident side 201 to the light emitting side 202 of the second thick-walled component 2. The second dividing surface is the end surface of the first part 206 away from one end of the second part 207, and an avoidance groove 204 is formed between the first part 206 and the second part 207.
[0047] To further optimize the above technical solution, the dimension of the first part 206 along the direction from the light incident side 201 to the light emitting side 202 of the second thick-walled component 2 is equal to the dimension of the first thick-walled component 1 from the direction from the light incident side 101 to the light emitting side 102. In this way, in the splicing position, the dimension of the first thick-walled component 1 from the light incident side 101 to the light emitting side 102 is the same as the dimension of the second thick-walled component 2 from the direction from the light incident side 201 to the light emitting side 202, which can further improve the optical continuity and uniformity.
[0048] Specifically, the first light-emitting element 3 includes a first light-guiding member and a first light source disposed at one end of the first light-guiding member, and the extension direction of the first light-guiding member is the same as the extension direction of the first thick-walled member 1. The second light-emitting element 4 includes a second light-guiding member and a second light source disposed at one end of the second light-guiding member, and the extension direction of the second light-guiding member is the same as the extension direction of the second thick-walled member 2.
[0049] Of course, it should be noted that the structure of the above-mentioned first light-emitting element 3 and the second light-emitting element 4 is only a preferred implementation scheme provided by the embodiment of the utility model, and is not actually limited to this. For example, the first light-emitting element 3 may include a plurality of first light sources spaced apart along the extension direction of the first thick-walled component 1, and the second light-emitting element 4 may include a plurality of second light sources spaced apart along the extension direction of the second thick-walled component 2.
[0050] like Figure 2 and Figure 5 As shown, the first thick-walled component 1 is provided with a first connecting portion 103, and the second thick-walled component 2 is provided with a second connecting portion 203. The first thick-walled component 1 and the second thick-walled component 2 are detachably connected via the first connecting portion 103 and the second connecting portion 203. The first thick-walled component 1 and the second thick-walled component 2 are fixed to each other via the first connecting portion 103 and the second connecting portion 203 to achieve relative positioning therebetween, so that the splicing structure of the first thick-walled component 1 and the second thick-walled component 2 is more stable, and it is not easy to have the problem of enlarged or uneven gaps at the splicing locations.
[0051] An embodiment of the utility model further provides a vehicle lamp, which includes the thick-walled light-guiding structure as described in the above embodiment. Since the vehicle lamp adopts the thick-walled light-guiding structure in the above embodiment, the technical effect of the vehicle lamp please refer to the above embodiment.
[0052] 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 or similar parts between the various embodiments can be referenced to each other.
[0053] This article uses specific examples to illustrate the principles and implementation methods of the utility model. The above examples are only used to help understand the core idea of the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
