Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of this application.

[0032] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections, electrical connections, or mutual communication; they can refer to direct connections or indirect connections through an intermediate medium; they can refer to internal communication between two components or the interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on specific circumstances.

[0033] The following will describe the vehicle lamp structure and vehicle lamp in this application in detail with reference to the accompanying drawings and specific embodiments.

[0034] In the prior art, welds and welding slag formed between parts in a headlight affect the propagation of light and reduce the light-guiding effect of the light-guiding component.

[0035] In order to solve the above technical problems, an embodiment of the present application provides a vehicle lamp structure, including a first light-guiding component and a first decorative component, wherein the first light-guiding component has a light-entry surface and a light-exiting surface arranged opposite to each other, and a connecting surface connected between the light-entry surface and the light-exiting surface; the first decorative component is fixed to the connecting surface by a first welding structure; wherein the first welding structure includes a first welding boss and a first welding leg, the first welding boss is arranged on the connecting surface, the first welding leg is arranged on the surface of the first decorative component facing the first light-guiding component, and the first welding leg is welded to the surface of the first welding boss. A first welding boss is arranged on the connecting surface of the first light-guiding component, and the weld seam and welding slag after the first welding boss and the first welding leg are welded are controlled on the first welding boss. Since the first welding boss protrudes from the connecting surface, the weld seam and welding slag will not affect the conduction of light inside the first light-guiding component, and will not affect its light-guiding effect. This will be explained in detail below.

[0036] See Figure 1 and Figure 2In one embodiment, the vehicle lamp structure includes a first light guide component 10 and a first decorative component 20. The first light guide component 10 has a light incident surface and a light emitting surface 11 arranged opposite to each other, and a connecting surface 12 connected between the light incident surface and the light emitting surface 11. The first decorative component 20 is arranged on the connecting surface 12 through a first welding structure 30; the first welding structure 30 includes a first welding boss 31 and a first welding leg 32. The first welding boss 31 is arranged on the connecting surface 12, and the first welding leg 32 is arranged on the surface of the first decorative component 20 facing the first light guide component 10, and the first welding leg 32 is welded to the surface of the first welding boss 31. The first welding boss 31 is protrudingly arranged on the connecting surface 12 of the first light guide component 10. After the first welding boss 31 and the first welding leg 32 are welded, the weld and the welding slag are controlled on the surface of the first welding boss 31, that is, the weld and the welding slag are controlled above the connecting surface 12 ( Figure 2 The light passing through the interior of the first light guide component 10 will not be disturbed by the weld and welding slag formed by welding, which effectively improves the light guiding effect of the first light guide component 10 and has a simple structure.

[0037] It should be noted that the welding between the first welding boss 31 and the first welding leg 32 is laser welding (laser is used as energy to melt the material to achieve welding between the materials), and the first light guide component 10 is a light-transmitting material, and the first decorative piece 20 is a light-absorbing material. When performing the welding operation, the welding head is moved from the bottom of the first light guide component 10 ( Figure 2 The welding operation is completed by aligning the first welding leg 32 with the first welding protrusion 31 in the horizontal direction (the same below) to ensure the welding effect. The welding head (welding laser) is perpendicular to the connecting surface 12 below the first light guide component 10. In this embodiment, the horizontal direction ( Figure 2 The viewing angle) size is 8mm, which provides a sufficient platform for the welding slag to prevent the welding slag from falling onto the first welding boss 31, thereby ensuring the light-conducting performance of the first welding component, and the welding width ( Figure 2 The horizontal dimension of the first welding leg 32 in the viewing angle is 2 mm, and the welding depth is 0.5 mm. In order to avoid the influence of the weld on the light guiding effect of the first light guide component 10, the protrusion height of the first welding boss 31 ( Figure 2 The longitudinal dimension in the viewing angle is correspondingly greater than 0.5 mm, for example, 1.5 mm. In some embodiments, it is determined according to actual welding requirements and is not limited thereto.

[0038] In some embodiments, in order to determine the welding position between the first welding boss 31 and the first welding leg 32 before welding, a positioning groove can be set on the table top of the first welding boss 31, and the first welding leg 32 can be clamped in the positioning groove. While the welding position between the first welding boss 31 and the first welding leg 32 can be quickly determined, the stability between the first welding boss 31 and the first welding leg 32 before welding can be ensured, thereby effectively improving the welding quality.

[0039] See Figure 2 In one embodiment, the first decorative member 20 is provided with a shielding boss 21, which is spaced apart on the side of the first welding boss 31 close to the light-emitting surface 11, that is, the shielding boss 21 is spaced apart on the left side of the first welding boss 31 ( Figure 2 viewing angle), and the minimum distance between the table surface of the shielding boss 21 and the connecting surface 12 facing the first decorative component 20 is less than the protruding height of the first welding boss 31. With this arrangement, when the headlight structure is viewed from the light-emitting surface 11 side, the weld and welding slag are blocked by the shielding boss 21, ensuring that the welding slag is invisible on the exterior and effectively improving the overall aesthetics.

[0040] It should be noted that the distance between the surface of the shielding boss 21 and the connecting surface 12 facing the first decorative member 20 is the distance between the shielding boss 21 in the longitudinal direction ( Figure 2 In some embodiments, the surface of the shielding boss 21 and the connecting surface 12 facing the first decorative component 20 can be parallel to each other, or the surface of the shielding boss 21 and the connecting surface 12 facing the first decorative component 20 can be inclined to each other, so as to ensure that when the headlight structure is viewed from the light-emitting surface 11 side, the shielding boss 21 can block the surface of the first welding boss 31 (weld and welding slag).

[0041] See Figure 1 and Figure 2 In one embodiment, the vehicle lamp structure further includes a second decorative member 40. The second decorative member 40 is disposed on a surface of the first light guide member 10 facing away from the first decorative member 20, that is, the first light guide member 10 is disposed between the first decorative member 20 and the second decorative member 40. The second decorative member 40 is fixed to the first light guide member 10 via a second welding structure 50. The second welding structure 50 includes a second welding boss 51 and a second welding leg 52. The second welding boss 51 is disposed on a surface of the first light guide member 10 facing away from the first decorative member 20, and the second welding leg 52 is disposed on a surface of the second decorative member 40 facing the first light guide member 10. The second welding leg 52 is welded to the surface of the second welding boss 51. The specific welding operation of the second welding structure 50 (the second welding boss 51 and the second welding leg 52) can be referred to the first welding structure 30 in the above embodiment and will not be repeated here. The weld and welding slag after the second welding boss 51 and the second welding leg 52 are welded are controlled on the surface of the second welding boss 51. Since the second welding boss 51 protrudes from the connecting surface 12 (the surface of the first light guide component 10 facing the second decorative part 40), the weld and welding slag will not affect the transmission of light inside the first light guide component 10, and will not affect its light guiding effect.

[0042] See Figure 2In one embodiment, the orthographic projection of the first welding leg 32 on the plane where the table surface of the first welding boss 31 is located is spaced from the orthographic projection of the second welding leg 52 on the plane where the table surface of the first welding boss 31 is located, that is, the first welding leg 32 and the second welding leg 52 are horizontally ( Figure 2 The second welding leg 52 is welded on the second welding boss 51 to provide an operating space (providing welding space for the welding head), which can be set at intervals on both sides of the first light guide component 10 ( Figure 2 In this embodiment, the shortest distance between the orthographic projection of the first welding leg 32 on the plane where the table surface of the first welding boss 31 is located and the orthographic projection of the second welding leg 52 on the plane where the table surface of the first welding boss 31 is located is L1 mm, and the following conditions are met: L1 ≥ 7, such as 7, 8, 9, 10, etc. When the value of L1 is less than 7, the lateral distance ( Figure 2 The value of L1 is determined according to the specific structure of the actual first decorative part 20 and the second decorative part 40; it has been verified that when L1 ≥ 7, it can ensure that the welding head has sufficient welding operation space.

[0043] See Figure 1 and Figure 3 In one embodiment, the vehicle lamp structure further includes a second light guide component 60, the second decorative member 40 is arranged between the first light guide component 10 and the second light guide component 60, and the second decorative member 40 is fixedly arranged on the surface of the second light guide component 60 facing the first light guide component 10 by a third welding structure 70; and the third welding structure 70 includes a third welding boss 71 and a third welding leg 72, the third welding boss 71 is arranged on the surface of the second light guide component 60 facing the first light guide component 10 (that is, the third welding boss 71 is arranged on the surface of the second light guide component 60 facing the first light guide component 10 Figure 3 The top surface of the second light-guiding component 60 in the viewing angle), the third welding leg 72 is arranged on the surface of the second decorative part 40 facing the second light-guiding component 60, and the third welding leg 72 is welded on the surface of the third welding boss 71. The specific welding operation of the third welding structure 70 (the third welding boss 71 and the third welding leg 72) can refer to the first welding structure 30 in the above embodiment, and will not be repeated here. The weld and welding slag after the third welding boss 71 and the third welding leg 72 are welded are controlled on the surface of the third welding boss 71. Since the third welding boss 71 protrudes from the connecting surface 12 (the surface of the second light-guiding component 60 facing the second decorative part 40), the weld and welding slag will not affect the transmission of light inside the second light-guiding component 60, effectively improving its light-guiding effect.

[0044] See Figure 1 、 Figure 2 and Figure 3In one embodiment, the second decorative member 40 includes a first cantilever portion 41, a main body portion 42, and a second cantilever portion 43 connected in sequence. The first cantilever portion 41 is arranged on a side of the second welding leg 52 close to the light exit surface 11, and the second cantilever portion 43 is arranged on a side of the third welding leg 72 close to the light exit surface 11. In this embodiment, the first cantilever portion 41, the main body portion 42, and the second cantilever portion 43 are connected in sequence to form an inverted C shape ( Figure 1 4 and 5. The second end of the second decorative piece 40 is welded to the first and second ends of the main body 42. The second end of the second decorative piece 40 is welded to the first and second ends of the main body 42. Figure 1 The second decorative part 40 is easy to shake after welding, which is not conducive to the stability of the overall structure. In actual use, the shaking will affect the stability of the light source, and the user experience of the car light will be poor.

[0045] In some embodiments, in order to avoid interference of the first cantilever portion 41 with the welding of the first decorative piece 20, during the actual welding operation, the first decorative piece 20 can be welded to the first light guide component 10 first, and then the second decorative piece 40 can be welded to the first light guide component 10; by welding in sequence, interference of the first cantilever portion 41 with the welding of the first decorative piece 20 is avoided.

[0046] See Figure 2 and Figure 3 In one embodiment, the minimum distance between the end of the first cantilever portion 41 away from the second welding leg 52 and the surface of the first light guide member 10 facing the second decorative member 40 is less than the protruding height of the second welding boss 51 ( Figure 2The minimum distance between the end of the second cantilever portion 43 distal from the third welding leg 72 and the surface of the second light guide component 60 facing the second decorative member 40 is less than the protruding height of the third welding boss 71. With this arrangement, when viewed from the light-emitting surface 11, the weld seam and welding slag on the second welding boss 51 and the third welding boss 71 are obscured by the first cantilever portion 41 and the second cantilever portion 43, ensuring that the welding slag is not visible and effectively improving the overall aesthetics.

[0047] It should be noted that the first cantilever portion 41 is away from the end of the second welding leg 52 to the first light guide component 10 facing the surface of the second decorative member 40 ( Figure 2 The minimum distance between the bottom surface of the first light guide member 10 in the viewing angle is the minimum distance between the free end of the first cantilever portion 41 (the end away from the second welding leg 52) in the longitudinal direction ( Figure 2 viewing angle) and the bottom surface of the first light guide member 10 ( Figure 2 Such a setting can ensure that when the headlight structure is viewed from the light-emitting surface 11 side, the first cantilever portion 41 can block the table surface (weld and welding slag) of the second welding boss 51; the second cantilever portion 43 is also the same, which will not be repeated here.

[0048] See Figure 2 In one embodiment, the end surface of the first cantilever portion 41 away from the second welding leg 52 is substantially coplanar with the end surface of the first decorative member 20 close to the light emitting surface 11. Such an arrangement can ensure that the upper and lower sides of the first light guide component 10 ( Figure 2 The visual consistency of the first decorative member 20 and the first cantilever portion 41 (seen from the light-emitting surface 11) improves the overall aesthetics.

[0049] It should be noted that, in this embodiment, the basic coplanarity can be that the end face of the first cantilever portion 41 away from the second welding leg 52 is coplanar with the end face of the first decorative component 20 close to the light-emitting surface 11, or the end face of the first cantilever portion 41 away from the second welding leg 52 is parallel to the end face of the first decorative component 20 close to the light-emitting surface 11 and the distance between the two end faces is small, or the end face of the first cantilever portion 41 away from the second welding leg 52 is set at a small angle to the end face of the first decorative component 20 close to the light-emitting surface 11, all of which can ensure visual consistency and enhance the overall aesthetics.

[0050] See Figure 2The longest distance between the end face of the first cantilever portion 41 away from the second welding leg 52 and the side face of the second welding leg 52 close to the light emitting surface 11 is L2 mm, satisfying: 7≤L2≤20, for example, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, etc. When the value of L2 is less than 7, the end face of the first cantilever portion 41 away from the second welding leg 52 is far away from the end face of the second decorative component 40 near the light-emitting surface 11, which is detrimental to visual consistency. When the value of L2 is greater than 20, the end face of the first cantilever portion 41 away from the second welding leg 52 is also far away from the end face of the second decorative component 40 near the light-emitting surface 11, which is detrimental to visual consistency. Furthermore, when the value of L2 is larger (i.e., the longer the first cantilever portion 41), the first cantilever portion 41 is prone to shaking, which is detrimental to overall stability. Vibration and impact during actual use can significantly affect the first cantilever portion 41. It has been verified that when 7 ≤ L2 ≤ 20, the first cantilever portion 41 is less likely to shake, the overall structure is stable, and the visual effect (consistency) is good. Furthermore, within this value range, the first cantilever portion 41 effectively shields the second welding boss 51, effectively shielding the weld and welding slag on the second welding boss 51 and improving the overall aesthetics.

[0051] See Figure 1 The vehicle lamp structure further includes a third decorative member 80, which is formed by injection molding on the surface of the second light guide member 60 away from the second decorative member 40. The corresponding production method is selected according to the material selection and usage requirements of each component during actual production.

[0052] On the other hand, the present application also relates to a headlight, comprising any one of the aforementioned headlight structures, the headlight comprising a lamp body 90, a light distribution mirror 91 and a printed circuit board 92, the lamp body 90 having a receiving cavity, the headlight structure and the printed circuit board 92 being arranged in the receiving cavity, and the light distribution mirror 91 covering the opening of the receiving cavity to seal the receiving cavity.

[0053] By adopting the technical solution provided in the embodiment of the present application, a first welding boss 31 is set on the connecting surface 12 of the first light-guiding component 10. The weld and welding slag after the first welding boss 31 is welded to the first welding leg 32 are controlled on the first welding boss 31. Since the first welding boss 31 protrudes from the connecting surface 12, the weld and welding slag will not affect the conduction of light inside the first light-guiding component 10, thereby effectively improving its light-guiding effect.
