Description

Technical Field

[0001] The present application relates to the field of vehicle lighting technology, and in particular to a lamp structure and a vehicle. Background Art

[0002] The current requirements for headlights are becoming more and more three-dimensional and profound. To achieve this effect, the luminous area mainly uses thick-walled light guides. However, the more three-dimensional the effect, the thicker the thick-walled light guide is, and the greater the size difference from the decorative ring is, the more light will hit the light distribution mirror on its light-emitting surface. When the light hits the edge of the light distribution mirror and the connection between the lamp body, it will present an unnecessary bright spot or reflection effect, which will reduce the exquisiteness of the whole lamp.

[0003] In addition, with the development of the automobile industry, the requirements for automobile lighting systems are getting higher and higher, and the functions are gradually increasing. If two-color injection molding cannot be used to complete the product due to some styling reasons, different parts can be welded together to meet the required production requirements. In the prior art, when welding multiple parts, welding slag will affect the propagation of light from the light-guiding component in the headlight, affect the light-guiding effect of the light-guiding component, and the welding slag and weld will affect the overall appearance of the headlight. Summary of the invention

[0004] The present application aims to solve at least one of the technical problems existing in the prior art and to provide a lamp structure and a vehicle.

[0005] According to one aspect of the present application, the present application provides a lamp structure, including:

[0006] The lamp body has a receiving cavity;

[0007] A light distribution mirror, which covers the opening of the accommodating cavity to block the accommodating cavity;

[0008] Wherein, the light distribution mirror comprises:

[0009] The first light distribution component includes a light entrance part and a light exit part;

[0010] A second light distribution component connected to the light incident portion, the second light distribution component comprising an overlapping surface, and a portion where the overlapping surface is connected to the light incident portion has an overlapping edge;

[0011] Wherein, an angle α is formed between the overlapping surface and the horizontal plane, and α is greater than or equal to 40° and less than or equal to 75°.

[0012] On the other hand, the present application also provides a vehicle, including a tailgate, wherein a trunk cover of the tailgate is provided with any of the above-mentioned lamp structures; and a water retaining assembly is further provided on the trunk cover, wherein the water retaining assembly includes:

[0013] A base body, provided with a through slot opening toward the rear of the vehicle, the through slot being used to accommodate the lamp structure; and

[0014] Two water retaining members are provided and fixedly mounted at opposite ends of the through slot through a connecting structure. The through slot and the two water retaining members cooperate to enclose an accommodating space;

[0015] Wherein, the base has an abutment surface facing the water retaining member; the water retaining member includes a main body and a water retaining portion, the water retaining portion is arranged on the side of the main body, and a portion of the surface of the water retaining portion away from the main body and close to the abutment surface is pressed against the abutment surface.

[0016] The angle α between the overlap surface and the horizontal plane of the present application is greater than or equal to 40° and less than or equal to 75°. After the part of the inclined light emitted from the light-emitting surface of the light-guiding component is incident on the overlap surface, it will be reflected obliquely upward. Compared with the solution in which the overlap surface of the traditional light distribution mirror is set horizontally, it can avoid reflecting the light directly in front of the light-emitting part of the light distribution mirror, so that the light is reflected to an area that is not visible from the front outside, and no obvious bright spot can be seen from the front.

[0017] The present application changes the optical path of the inclined light emitted by the light-guiding component so that the light no longer reflects forward to produce obvious brightness, thereby reducing bright spots or reflections and solving the problem of stray light easily generated when light hits the connection between the light distribution lens and the lamp body.

[0069] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0070] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or mutual communication; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0071] The lamp structure and vehicle lamp in the present application will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0072] In the prior art, the welds and welding slag formed by welding parts between parts in the vehicle lamp affect the propagation of light and reduce the light guiding effect of the light guiding component.

[0073] In order to solve the above technical problems, the embodiment of the present application provides a lamp structure, including a first light guide component and a first decorative component, wherein the first light guide component has a light incident surface and a light emitting surface arranged opposite to each other and a connecting surface connected between the light incident surface and the light emitting 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, wherein 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 guide component, and the first welding leg is welded to the table of the first welding boss. The first welding boss is arranged on the connecting surface of the first light guide 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 guide component, and will not affect its light guiding effect. The following light guide component can be a functional lamp such as a turn signal lamp, a position lamp, a brake lamp, etc., which is not limited by the present application, and the details of the scheme will be elaborated in detail below.

[0074] See also Figure 2 and Figure 3In one embodiment, the lamp structure includes a lamp body 90, a light distribution mirror 91 and a printed circuit board 92, the lamp body 90 has a receiving cavity, the printed circuit board 92 is arranged in the receiving cavity, and the light distribution mirror 91 is covered at the opening of the receiving cavity to block the receiving cavity; the first light guide component 10 and the first decorative member 20 are arranged in the receiving cavity, 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 member 20 is arranged on the connecting surface 12 through a first welding structure 30; the first welding structure 30 includes a first welding boss 30a and a first welding leg 30b, the first welding boss 30a is arranged on the connecting surface 12, the first welding leg 30b is arranged on the surface of the first decorative member 20 facing the first light guide component 10, and the first welding leg 30b is welded on the surface of the first welding boss 30a. The first welding boss 30a is protrudingly arranged on the connection surface 12 of the first light guide member 10. After the first welding boss 30a and the first welding leg 30b are welded, the weld and the welding slag are controlled on the surface of the first welding boss 30a, and the first welding boss 30a protrudes from the connection surface 12, that is, the weld and the welding slag are controlled on the upper part of the connection surface 12 ( Figure 3 In this case, the light passing through 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.

[0075] It should be noted that the welding between the first welding boss 30a and the first welding leg 30b is laser welding (using laser 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 member 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 3 The welding operation is completed by aligning the first welding leg 30b with the first welding protrusion 30a in the horizontal direction (in the horizontal direction) of the first welding protrusion 30a. In order to ensure the welding effect, the welding head (welding laser) is perpendicular to the connecting surface 12 below the first light guide component 10. Figure 3 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 30a, thereby ensuring the light-conducting performance of the first welding component, and the welding width ( Figure 3 The lateral dimension of the first welding leg 30b 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 guiding component 10, the protrusion height of the first welding boss 30a ( Figure 3 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, but is not limited to this.

[0076] In some embodiments, in order to determine the welding position between the first welding boss 30a and the first welding leg 30b before welding, a positioning groove can be set on the surface of the first welding boss 30a, and the first welding leg 30b can be snapped into the positioning groove. While the welding position between the first welding boss 30a and the first welding leg 30b can be quickly determined, the stability between the first welding boss 30a and the first welding leg 30b before welding can be ensured, thereby effectively improving the welding quality.

[0077] See also Figure 3 In one embodiment, the first decorative member 20 is provided with a shielding boss 20a, and the shielding boss 20a is arranged at intervals on the side of the first welding boss 30a close to the light emitting surface 11, that is, the shielding boss 20a is arranged at intervals on the left side of the first welding boss 30a ( Figure 3 viewing angle), and the minimum distance between the table surface of the shielding boss 20a and the connecting surface 12 facing the first decorative member 20 is smaller than the protruding height of the first welding boss 30a. With such an arrangement, when the lamp structure is viewed from the light-emitting surface 11 side, the weld and welding slag are blocked by the shielding boss 20a, thereby ensuring that the welding slag is invisible on the exterior and effectively improving the overall aesthetics.

[0078] It should be noted that the distance between the table surface of the shielding boss 20a and the connecting surface 12 facing the first decorative member 20 is the distance between the shielding boss 20a in the longitudinal direction ( Figure 3 In some embodiments, the top of the shielding boss 20a and the connecting surface 12 facing the first decorative component 20 can be parallel to each other, or the top of the shielding boss 20a and the connecting surface 12 facing the first decorative component 20 can be inclined to ensure that when the lamp structure is viewed from the light emitting surface 11 side, the shielding boss 20a can shield the top of the first welding boss 30a (weld and welding slag).

[0079] See also Figure 2 and Figure 3In one embodiment, the lamp structure further includes a second decorative member 40, which is arranged on the surface of the first light guide member 10 away from the first decorative member 20, that is, the first light guide member 10 is arranged between the first decorative member 20 and the second decorative member 40, and the second decorative member 40 is fixedly arranged on the first light guide member 10 through 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 arranged on the surface of the first light guide member 10 away from the first decorative member 20, the second welding leg 52 is arranged on the surface of the second decorative member 40 facing the first light guide member 10, and the second welding leg 52 is welded on 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 refer 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 is welded to the second welding leg 52 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 conduction of light inside the first light guide component 10, and will not affect its light guiding effect.

[0080] See also Figure 3 In one embodiment, the orthographic projection of the first welding leg 30b on the plane where the table surface of the first welding boss 30a 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 30a is located, that is, the first welding leg 30b and the second welding leg 52 are horizontally ( Figure 3 The second welding leg 52 is welded on the second welding boss 51 to provide an operating space (providing a welding space for the welding head), and can be on both sides of the first light guide component 10 ( Figure 3 In this embodiment, the shortest distance between the orthographic projection of the first welding leg 30b on the plane where the table surface of the first welding boss 30a is located and the orthographic projection of the second welding leg 52 on the plane where the table surface of the first welding boss 30a is located is L1 mm, satisfying: L1 ≥ 7, such as 7, 8, 9, 10, etc.; when the value of L1 is less than 7, the lateral distance ( Figure 3 The viewing angle) spacing is too small, which is not conducive to the operation of the welding head and affects the welding quality; 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.

[0081] See also Figure 2 and Figure 4In one embodiment, the 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 through a third welding structure 70; and the third welding structure 70 includes a third welding boss 71 and a third welding leg 72, and 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 4 The third welding leg 72 is arranged on the surface of the second decorative part 40 facing the second light guide 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 guide component 60 facing the second decorative part 40), the weld and welding slag will not affect the conduction of light inside the second light guide component 60, and its light guiding effect is effectively improved.

[0082] See also Figure 2 , Figure 3 and Figure 4 In one embodiment, the second decorative member 40 has 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 emitting surface 11, and the second cantilever portion 43 is arranged on a side of the third welding leg 72 close to the light emitting 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 2 4 and 5. The second decorative member 40 and the second decorative member 40 are connected to the first decorative member 40 and the second decorative member 40. The second decorative member 40 and the second decorative member 40 are connected to the second decorative member 40. The second decorative member 40 and the second decorative member 40 are connected to the second decorative member 40. The second decorative member 40 and the second decorative member 40 are connected to the second decorative member 40. The second decorative member 40 and the third decorative member 40 are connected to the second decorative member 40. The second decorative member 40 and the third decorative member 40 are connected to the second decorative member 40. The second decorative member 40 and the third decorative member 40 are connected to the second decorative member 40. Figure 2 The second decorative part 40 is easily shaken 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.

[0083] In some embodiments, in order to prevent the first cantilever portion 41 from interfering with the welding of the first decorative piece 20, during the actual welding operation, the first decorative piece 20 can be first welded to the first light guide component 10, and then the second decorative piece 40 can be welded to the first light guide component 10; by welding in sequence, the first cantilever portion 41 is prevented from interfering with the welding of the first decorative piece 20.

[0084] See also Figure 3 and Figure 4 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 3 The minimum distance between the end of the second cantilever portion 43 away from the third welding leg 72 and the surface of the second light guide member 60 facing the second decorative member 40 is less than the protruding height of the third welding boss 71. In this way, when the lamp structure is viewed from the light emitting surface 11, the weld seams and welding slag on the second welding boss 51 and the third welding boss 71 are blocked by the first cantilever portion 41 and the second cantilever portion 43, ensuring that the welding slag is invisible, and effectively improving the overall aesthetics.

[0085] 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 3 The minimum spacing between the bottom surface of the first light guide member 10 in the viewing angle is the minimum spacing between the free end of the first cantilever portion 41 (the end away from the second welding leg 52) in the longitudinal direction ( Figure 3 viewing angle) and the bottom surface of the first light guide member 10 ( Figure 3 This arrangement ensures that when the lamp structure is viewed from the light-emitting surface 11, the first cantilever portion 41 can shield the table surface (weld and welding slag) of the second welding boss 51; the same is true for the second cantilever portion 43, which will not be repeated here.

[0086] See also Figure 3 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 ( Figure 3 The visual consistency of the first decorative member 20 and the first cantilever portion 41 (seen from the light emitting surface 11 side) improves the overall aesthetics.

[0087] It should be noted that, in the present 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.

[0088] See also Figure 3 The 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 member 40 close to the light-emitting surface 11, which is not conducive 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 member 40 close to the light-emitting surface 11, which is not conducive to visual consistency, and when the value of L2 is larger (that is, the longer the first cantilever portion 41 is), the first cantilever portion 41 is easy to shake, which is not conducive to overall stability. The vibration and impact during actual use will have a greater impact on the first cantilever portion 41. It has been verified that when 7≤L2≤20, the first cantilever portion 41 is not easy to shake, the overall structure is stable, and the visual effect (consistency) is good. At the same time, within this value range, the first cantilever portion 41 has a good shielding effect on the second welding boss 51, and can better shield the weld and welding slag on the second welding boss 51, thereby improving the overall appearance.

[0089] See also Figure 2 The 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. According to the material selection and use requirements of each part in actual production, the corresponding production method is selected.

[0090] The current requirements for the shape of car lights are becoming more and more three-dimensional and profound. To achieve this effect, the luminous area mainly uses thick-walled light guides. The thicker the thick-walled light guide is, the thicker it needs to be. The more light will hit the light distribution mirror on its light-emitting surface. When light hits the edge of the light distribution mirror and the connection between the lamp body, it will present an unnecessary bright spot or reflection, which will reduce the exquisiteness of the whole lamp. Figure 5 It can be seen that a large amount of light will be reflected to the edge of the lens to form stray light and shadow.

[0091] Specifically, the applicant has found that the fundamental reason for the above-mentioned problem is that when the lamp is on, when the light emitted from the light-emitting surface 11 of the thick-walled first light-guiding component 10 hits the overlap between the different color parts in the two-color or multi-color light-distributing lens 91, the highlight surface of the overlap will reflect the light forward of the light-emitting surface of the lamp, directly resulting in stray bright spots or reflections.

[0092] refer to Figure 6 and Figure 7 The light distribution lens 91 comprises:

[0093] The first light distribution component 910 includes a light entrance part 911 and a light exit part 912;

[0094] A second light distribution component 920 connected to the light incident portion 911, wherein the second light distribution component 920 comprises an overlapping surface 921, and a portion where the overlapping surface 921 is connected to the light incident portion 911 has an overlapping edge line;

[0095] Therein, an angle α is formed between the overlapping surface 921 and the horizontal plane, and α is greater than or equal to 40° and less than or equal to 75°.

[0096] The light distribution mirror 91 is a light-transmitting component installed on the light-emitting side of the lamp, and is specifically arranged in the light-emitting direction of the first light guide component 10. In the direction gradually away from the first light guide component 10, the light entrance part 911 and the light exit part 912 of the first light distribution component 910 are arranged in sequence. Most of the light emitted from the light exit surface of the first light guide component 10 enters the first light distribution component 910 through the light entrance part 911, and then is emitted from the light exit part 912 to form the expected light type such as low beam, high beam, etc. Among them, the first light distribution component 910 and the second light distribution component 920 of the light distribution mirror 91 have different colors respectively, and can be specifically formed by two-color injection molding. The second light distribution component 920 is arranged at the edge of the first light distribution component 910, and the second light distribution component 920 is connected to the edge of the lamp body 90.

[0097] Specifically, the angle α between the overlapping surface 921 and the horizontal plane is greater than or equal to 40° and less than or equal to 75°, and part of the inclined light emitted from the light emitting surface of the first light guide component 10 is reflected obliquely upward after being incident on the overlapping surface 921. Compared with the solution in which the overlapping surface 921 of the traditional light distribution mirror is horizontally arranged, it can avoid reflecting the light directly in front of the light emitting portion 912 of the light distribution mirror, so that the light is reflected to an area that is not visible from the outside front, and no obvious bright spot can be seen from the front.

[0098] The present application changes the optical path of the inclined light emitted by the first light guide component 10 so that the light no longer reflects forward to produce obvious brightness, thereby reducing bright spots or reflections and solving the problem of stray light easily generated at the connection between the light distribution lens 91 and the lamp body 90 .

[0099] In some embodiments, the angle α between the overlapped surface 921 and the horizontal plane is greater than or equal to 45° and less than or equal to 75°. In this embodiment, the angle α has a larger range of values. Fig. 9 This is a simulated light distribution diagram when α is 45°. It can be seen that when α is 45°, the light visible from the outside is significantly reduced and the bright spot is significantly weakened. Fig. 9 It can be seen that the brightness of the two-color overlapping part of the edge of the photosensitive lens is significantly reduced, indicating that the amount of light mapped to the two-color overlapping part of the photosensitive lens is significantly reduced.

[0100] Moreover, when α is greater than or equal to 45° and less than or equal to 75°, better light effects are produced; on this basis, further setting shallower leather textures on the overlap surface 921 can achieve excellent light effects. At this time, the specifications of the leather textures can be freely selected, and the depth and roughness of the leather textures are more optional (basically any leather texture model on the market can be selected), and the cost and processing difficulty are lower.

[0101] refer to Fig.10 In some embodiments, the surface of the light path adjustment surface 921a has a dermatoglyphic structure.

[0102] Specifically, if Fig.10 As can be seen from the light path diagram, the surface of the light path adjustment surface 921a of this embodiment has a leather grain structure which can diffuse and scatter the light irradiated to the surface, turning it into diffusely reflected light, further reducing and weakening the intensity of the reflected light, weakening the stray light effect, and making the bright spots or reflections seen from the outside less obvious.

[0103] refer to Figure 8 In some embodiments, in the direction gradually approaching the overlapping edge (light emitting direction), the overlapping surface 921 includes an optical path adjustment surface 921a and an overlapping edge surface 921b arranged in sequence, and the width L of the overlapping edge surface 921b is 0.5-1.0mm.

[0104] When the overlapping parts of the two-color or multi-color injection molding are all made into leather grain structure, when the surface leather grain treatment is performed on the overlapping surface 921, material leakage occurs on the light incident part 911 of the first light distribution component 910 and also forms a leather grain structure, which leads to a significant deviation between the light effect of the light emitted from the light distribution lens and the expected light effect.

[0105] In this embodiment, an overlapping edge surface 921b with a width L of 0.5-1.0mm along the light emitting direction is reserved on the overlapping surface 921. In this case, the optical path adjustment surface 921a is not directly connected to the light incident portion 911 of the first light distribution component 910 and has a width interval of 0.5-1.0mm. There is an obvious spacing of 0.5-1.0mm between the leather grain structure and the light incident portion 911 of the first light distribution component 910, which can avoid material leakage to the light incident portion 911 of the first light distribution component 910 when performing surface leather grain treatment on the overlapping surface 921, and the light emitted from the light distribution mirror can form the expected complete light pattern.

[0106] refer to Figure 8 In some embodiments, the width L of the overlapping edge surface 921b along the light emitting direction is 0.5 mm. In this embodiment, the width L of the overlapping edge surface 921b takes the minimum value of 0.5 mm, so that the area ratio of the leather grain structure on the entire overlapping surface 921 will be the largest, which can scatter light to the greatest extent, reduce reflected light, basically eliminate stray light, and basically no bright spots or reflections can be seen from the outside.

[0107] Further, such as Figure 8 , the angle β between the cut surface of the light incident portion 911 at the overlapped edge and the overlapped edge surface 921b is 90°±30°. In this embodiment, when the special setting of β being 90°±30° is adopted, even if part of the inclined light hits the narrow overlapped edge surface 921b, the overlapped edge surface 921b will reflect the part of the light obliquely upward, thereby avoiding reflecting part of the light directly in front of the light exit portion 912 of the light distribution lens to produce stray light effect.

[0108] refer to Figure 8 In some embodiments, the angle α between the overlapping surface 921 and the horizontal plane is in the range of 40°-45°, and the depth of the dermatoglyphic structure is in the range of 6-8 μm.

[0109] Specifically, the angle α formed between the overlapping surface 921 (or the optical path adjustment surface 921a) and the horizontal plane is in the range of 40°-45°, which can effectively change the direction of the reflected light and reduce the bright spots or reflections. In this case, a leather grain structure with a depth of 6-8μm, such as the K31 model, can be selected. It has low cost and reduces the difficulty of surface leather grain processing. The solution has the highest cost-effectiveness and is a commonly used choice.

[0110] refer to Figure 8 In some embodiments, the angle α between the overlapping surface 921 and the horizontal plane ranges from 45° to 75°, and the depth of the dermatoglyphic structure ranges from 8 to 10 μm.

[0111] In this embodiment, the angle α formed between the overlapping surface 921 (or the optical path adjustment surface 921a) and the horizontal plane is in the range of 45°-75°, which has a better reflection effect on light and less stray light formed after reflection; in this case, it is appropriate to select a coarser leather texture with a depth range of 8-10μm, such as the leather texture of the K33 model or the K35 model, which is best for eliminating bright spots or reflections, and bright spots or reflections are rarely seen from the front.

[0112] At present, in order to meet the shape of the whole vehicle, more and more decorative parts have appeared. Many decorative parts are connected to the photometric mirror. Due to the special-shaped structure of the decorative parts themselves and the limitation of the shape of the photometric mirror, the installation stability of the decorative parts is not high after being connected to the photometric mirror and they are easy to fall off the photometric mirror.

[0113] See also Figure 11-13 Now, a decorative structure provided in an embodiment of the present application is described. The decorative structure includes a bracket 101 and a decorative member 102. The bracket 101 is used to be detachably connected to the light distribution lens 91, and the decorative member 102 is clamped on the bracket 101 and forms a preset decorative shape on a side away from the bracket 101.

[0114] According to the structure of the bracket 101 and the decorative member 102 provided in this embodiment, the function of the bracket 101 is to connect the decorative member 102 and the light distribution mirror 91. Since the bracket 101 can be flexibly set to be adapted to the shape of the decorative member 102 and the light distribution mirror 91, it can well solve the problem of poor connection stability between the decorative member 102 and the light distribution mirror 91 in the prior art due to the special shapes of the decorative member 102 and the light distribution mirror 91. When the decorative member 102 is indirectly connected to the light distribution mirror 91 through the bracket 101, the bracket 101 can form a better connection stability between the decorative member 102 and the light distribution mirror 91, thereby enabling the decorative member 102 in this application to form a better installation stability, which is far superior to the prior art.

[0115] It can be understood that the manner in which the bracket 101 in this embodiment can be detachably connected to the light distribution lens 91 includes but is not limited to the commonly used clamping, rivet connection, or threaded connection formed by screws 203 or bolts in the art. The clamping method between the decorative member 102 and the bracket 101 can be a damping connection, interference connection, and a clamping method formed by the cooperation of a clamp block and a clamping slot, etc., which are commonly used in the art. Other clamping methods in the art that can make the bracket 101 detachably connected to the light distribution lens 91 and other clamping methods that can make the decorative member 102 clamped to the bracket 101 can be regarded as common variations of the above-mentioned connection methods in this embodiment, and will not be repeated here.

[0116] In another embodiment of the present application, please refer to Figure 11-13The decorative element 102 has a decorative portion 121 for forming a decorative shape and a clamping portion 122 for connecting with the decorative portion 121 , and the decorative element 102 is clamped with the bracket 101 via the clamping portion 122 .

[0117] According to the above structure provided in this embodiment, since the decorative part 102 has independently processed decorative parts 121 and clamping parts 122, this can not only reduce the processing difficulty of the decorative part 102 and enable the decorative part 102 to meet higher appearance requirements, but also enable the decorative part 102 to be more stably clamped to the bracket 101 through the clamping part 122 and improve its own installation stability.

[0118] It can be understood that in order to meet the higher appearance requirements of the decorative part 102, the decorative part 121 and the clamping part 122 in this embodiment can also be set to be detachably connected. For example, in this embodiment, the decorative part 121 and the clamping part 122 can be set to be bonded to each other. By setting the decorative part 102 to be formed by the clamping part 122 and the decorative part 121 being bonded to each other, not only can the decorative part 121 be processed more conveniently to meet higher appearance requirements, but the clamping part 122 can also be processed more conveniently, so that the clamping part 122 can be more stably clamped on the bracket 101, which is conducive to further improving the installation stability of the decorative part 102.

[0119] In addition, the clamping portion 122 that can be separated from the decorative portion 121 and processed independently can be clamped to the bracket 101 in a more flexible manner, which is conducive to significantly reducing the overall structural size of the decorative part 102 and allowing the decorative part 102 provided in this embodiment to meet higher appearance requirements. For example, the clamping portion 122 that can be processed independently in this embodiment can be set as a flat card structure and clamped with the card slot structure set on the bracket 101, so that the above-mentioned technical effect of reducing the overall structural size of the decorative part 102 can be achieved. Of course, other structures in the art that can reduce the size of the clamping structure between the decorative part 102 and the bracket 101 can also be regarded as common variations of the above-mentioned structure in this embodiment, and will not be repeated here.

[0120] In another embodiment of the present application, please refer to Figure 11-13 The decorative structure further includes a buckle 103, which is detachably connected to the clamping portion 122 and the bracket 101 respectively.

[0121] According to the above structure provided in this embodiment, the buckle 103 that can be respectively engaged with the engaging portion 122 and the bracket 101 can not only further reduce the difficulty of processing the decorative component 102, but also enable the engaging portion 122 to be more stably engaged with the bracket 101, thereby effectively improving the installation stability of the decorative component 102.

[0122] It can be understood that the buckle 103 in this embodiment can be set as a commonly used snap-fit ​​structure in the art, and the decorative member 102 and the bracket 101 can be quickly snap-fitted by snapping it into the slot on the bracket 101 or the snap-fit ​​122. Of course, in this embodiment, the buckle 103 can also be provided with a slot corresponding to the bracket 101 and the snap-fit ​​portion 122, and the decorative member 102 and the bracket 101 can also be quickly snap-fitted. In other embodiments of the present application, the buckle 103 can also be set to be integrally formed with the bracket 101 or integrally formed with the snap-fit ​​portion 122, respectively, with a snap-fitting effect similar to that in this embodiment, which will not be repeated here.

[0123] Please also read Figure 12-14 The light-emitting surface of the light distribution mirror 91 is recessed toward the inside of the lamp to form a receiving groove 201 , and the bracket 101 and the decorative component 102 are located inside the receiving groove 201 .

[0124] According to the above structure provided in this embodiment, by forming the receiving groove 201 on the light-emitting surface of the light distribution mirror 91, the decorative member 102 can not only meet the same curvature surface as the light distribution mirror 91 but also not protrude from the light distribution mirror 91. The receiving groove 201 can also be used to form a protective effect on the bracket 101 and the decorative member 102 inside the receiving groove 201, which is conducive to further improving the installation stability of the decorative member 102.

[0125] It can be understood that the depth of the receiving groove 201 in this embodiment may not be limited, as long as it can accommodate the bracket 101 and the decorative member 102. In other embodiments of the present application, for the sake of the overall structural beauty, the depth of the receiving groove 201 can be set to match the overall height of the decorative member 102 and the bracket 101, so that a more beautiful decorative effect can be achieved. In addition, the shape of the receiving groove 201 is not limited, and can be a circular groove, a square groove, or a polygonal groove commonly used in the art. Similarly, in other embodiments of the present application, for the sake of the overall structural beauty, the shape of the receiving groove 201 can be set to match the overall shape of the decorative member 102 and the bracket 101 to achieve a better decorative effect.

[0126] In another embodiment of the present application, please refer to Figure 12-14 , the light distribution mirror 91 has a plurality of connecting posts 202 protruding from the bottom of the receiving groove 201 along the groove depth direction of the receiving groove 201, and the connecting posts 202 and the bracket 101 are correspondingly formed with screw holes along the extending direction of the connecting posts 202 and are connected to each other through a connecting piece axially inserted into the screw hole. In this embodiment, the groove depth direction of the receiving groove 201 is Fig.12It is understood that the connecting member that can be installed in the screw hole in this embodiment can be a screw 203 or a bolt commonly used in the art. For ease of description, this embodiment is described by taking the connecting member as a screw 203 as an example.

[0127] According to the above structure provided in the present embodiment, the connecting column 202 protruding from the bottom of the accommodating groove 201 in the present embodiment can be provided with a deeper screw hole by utilizing the space in the depth direction of the accommodating groove 201. In this way, when the connecting column 202 and the bracket 101 are connected by the screw 203 installed in the screw hole, the screw 203 and the screw hole can form a larger connection contact area, which is beneficial to further improve the installation stability of the bracket 101, thereby further improving the installation stability of the decorative part 102.

[0128] It is understood that the cross-sectional shape of the connecting column 202 itself in this embodiment is not limited, and can be selected to be a circular, rectangular or polygonal shape commonly used in the art, as long as the purpose of setting the screw hole is met. In addition, the connecting column 202 and the screw hole can also be set at an angle relative to the horizontal direction, so that the screw hole can extend in the height direction of the connecting column 202 to achieve the technical effect of increasing the installation stability of the bracket 101 in this embodiment.

[0129] In another embodiment of the present application, please refer to Figure 12-14 A main positioning column 204 is provided on the light distribution lens 91 . The main positioning column 204 is adjacent to and connected to the connecting column 202 . The main positioning column 204 is slidably connected to the bracket 101 and can provide a sliding guide for the bracket 101 during the threaded connection process between the bracket 101 and the connecting column 202 .

[0130] According to the above structure provided in this embodiment, the main positioning column 204 can not only enable the bracket 101 to be installed in the receiving groove 201 more efficiently through the sliding connection with the bracket 101, but also form a support limit for the bracket 101 after the bracket 101 is installed and fixed, which is beneficial to further improve the installation stability of the bracket 101, thereby further improving the installation stability of the decorative component 102.

[0131] It can be understood that the cross-sectional shape of the main positioning column 204 in this embodiment is not limited, and can be selected to be a circular, rectangular or polygonal structure commonly used in the art. In addition, the main positioning column 204 can also be provided with a positioning structure such as a slide groove, a slide rail, etc., which is used to correspond to the bracket 101 and enable the bracket 101 to slide relative to the positioning column. This embodiment is a preferred embodiment, and the main positioning column 204 is set as a step with a circular cross-section as an example for explanation. In the lamp provided in this embodiment, the main positioning column 204 can use its inclined annular side wall as a positioning structure of the bracket 101 and form abutment against the bracket 101 after the bracket 101 and the connecting column 202 are installed in place, which can provide better installation stability for the bracket 101.

[0132] In another embodiment of the present application, please refer to Figure 12-14 The light distribution mirror 91 is provided with an auxiliary positioning column 205 spaced apart from the main positioning column 204 . The auxiliary positioning column 205 is slidably connected to the bracket 101 and can provide a sliding guide for the bracket 101 during the threaded connection process between the bracket 101 and the connecting column 202 .

[0133] According to the above structure provided in the present embodiment, by providing an auxiliary positioning column 205 that cooperates with the main positioning column 204, not only the efficiency and stability of the bracket 101 during installation can be improved, but the auxiliary positioning column 205 can also cooperate with the main positioning column 204 to form at least two spaced abutment positions on the light distribution mirror 91, which is beneficial to further improve the installation stability of the bracket 101, thereby further improving the installation stability of the decorative component 102.

[0134] It can be understood that the cross-sectional shape of the auxiliary positioning column 205 in this embodiment is not limited, and can be selected to be a circular, rectangular or polygonal structure commonly used in the art. In addition, the auxiliary positioning column 205 can also be provided with a positioning structure such as a slide groove, a slide rail, etc., which is used to correspond to the bracket 101 and enable the bracket 101 to slide relative to the auxiliary positioning column 205. This embodiment is a preferred embodiment, and the auxiliary positioning column 205 is set as a step with a circular cross-section as an example for explanation. In the lamp provided in this embodiment, the auxiliary positioning column 205 can use its inclined annular side wall as a positioning structure of the bracket 101 and form abutment against the bracket 101 after the bracket 101 and the connecting column 202 are installed in place, which can provide better installation stability for the bracket 101.

[0135] Please note that, see Fig.15In this embodiment, the light distribution mirror 91 can be prepared by injection molding, wherein the auxiliary positioning column 205 can be the gate of the light distribution mirror 91 during injection molding, so that the auxiliary positioning column 205 can be formed by using the gate of the light distribution mirror 91, which not only saves the production cost of the light distribution mirror 91, but also can achieve a more stable installation effect of the bracket 101 through the above-mentioned function of the auxiliary positioning column 205, which is far better than the existing technology. In the actual production process, the residual height of the auxiliary positioning column 205 as the gate can be set to 17±0.5mm, and the diameter can be set to 2.3(0,-0.1)mm, so as to ensure that the auxiliary positioning column 205 plays the role of auxiliary positioning and ensure that the bracket 101 will not move on the light distribution mirror 91.

[0136] In other embodiments of the present application, please refer to Fig.16 In order to further reduce the production cost of the light distribution lens 91, the light distribution lens can choose a false three-color injection molding method, in which two of the raw materials (B\C) are completely separated by another raw material (A) to form a mutually spaced B injection molding area 208, a C injection molding area 209 and an A injection molding area 207 located between the B injection molding area 208 and the C injection molding area 209, which has a better cost saving effect.

[0137] In another embodiment of the present application, please refer to Figure 12-14 The bottom of the receiving groove 201 is provided with a plurality of auxiliary positioning surfaces 206 , which match the surface shape of the bracket 101 and can provide sliding guidance for the process of installing the bracket 101 into the receiving groove 201 or removing it from the receiving groove 201 .

[0138] According to the above structure provided in the present embodiment, the auxiliary positioning surface 206 provided at the bottom of the receiving groove 201 can not only enable the bracket 101 to be installed into the receiving groove 201 more efficiently, but also cooperate with the main positioning column 204 and the auxiliary positioning column 205 to limit the bracket 101, thereby preventing the bracket 101 from shaking in the receiving groove 201, which is beneficial to further improve the installation stability of the bracket 101, thereby further improving the installation stability of the decorative component 102.

[0139] It is understood that the shape of the auxiliary positioning surface 206 in this embodiment is not limited, and can be selected as a circular, rectangular or polygonal shape commonly used in the art. In order to facilitate the formation of a sliding guide for the bracket 101, the auxiliary positioning surface 206 in this embodiment can be set to be inclined relative to the horizontal direction, so that the bracket 101 can make the process of the bracket 101 being installed into the receiving groove 201 more stable and fast. In addition, the auxiliary positioning surface 206 protruding from the bottom of the receiving groove 201 in this embodiment can also be set to protrude with a certain thickness or height, so as to ensure good structural strength and enable the lamp provided in this embodiment to be used stably for a long time.

[0140] In another embodiment of the present application, please refer to Figure 12-14 together. The auxiliary positioning surface 206 is provided with at least two and is respectively close to two groove walls extending along different directions of the accommodating groove 201, and the extending direction of the auxiliary positioning surface 206 is the same as that of the groove wall it is close to.

[0141] According to the above structure provided in this embodiment, at least two auxiliary positioning surfaces 206 can be arranged around the bracket 101, so as to better limit the shaking of the bracket 101 in the accommodating groove 201, which is beneficial to further improving the installation stability of the bracket 101, and thus can also further improve the installation stability of the decorative part 102.

[0142] It can be understood that as Fig.12 shown, the auxiliary positioning surfaces 206 located in different directions can be connected to each other, so as to form a combined auxiliary positioning surface 206 in an "L" shape or a "匚" shape, which is beneficial to forming a better auxiliary positioning effect on the bracket 101.

[0143] Currently, there are more and more through lights at the rear of new energy vehicles. However, due to their relatively long length, the deformation amount of the parts is relatively large. And the existing lamp bodies are usually directly fixed on the vehicle frame. Once the lamp body is deformed, it will cause the lamp body to protrude or be lower than the front surface of the vehicle head after installation, and it cannot match the overall vehicle size, so it can only be scrapped. Moreover, the existing lamp bodies can only be installed at fixed positions and cannot be adjusted, so they cannot be flexibly adapted to different scenarios and different vehicle models, resulting in poor flexibility in the use of existing lamps.

[0144] Please refer to the attached Figures 17-18 . In the embodiment of the present application, the vehicle frame 1 serves as a supporting component for the lamp body, and the vehicle frame 1 is used to support the lamp body module 20. Optionally, the vehicle frame 1 is formed by bending, aluminum extrusion or casting, which is not limited herein. The vehicle frame 1 has a certain rigidity.

[0145] In the embodiment of the present application, the lamp body 90 is assembled on the vehicle frame 1 and is subjected to the supporting force of the vehicle frame 1. At this time, the screw 92 is arranged on the side of the lamp body 90 facing the vehicle frame 1. The screw 92 is embedded in the lamp body 90 and is an integrated connection structure with the lamp body 90, which ensures the connection stability between the screw 92 and the lamp body 90 and improves the hardness of the connection part between the screw 92 and the lamp body 90. The screw 92 is also screwed on the vehicle frame 1, and the distance between the lamp body 90 and the vehicle frame 1 is adjusted through rotational cooperation to adjust the distance between the lamp body 90 and the vehicle frame 1, so as to facilitate changing the position of the lamp body 90 relative to the vehicle frame 1, adapt to different assembly scenarios, ensure the installation flexibility of the lamp body module 20 relative to the vehicle frame 1, and at the same time ensure the versatility of the lamp body.

[0146] At this time, the lamp body 90 is provided with a melting connection area 91a; in the heated state, the screw 92 forms a hot screw 92 and is arranged relative to the melting connection area 91a, so that the screw 92 is embedded in the lamp body 90 by melting, so that the screw 92 is integrally connected to the lamp body 90, thereby ensuring the connection stability between the screw 92 and the lamp body 90 and improving the hardness of the connection between the screw 92 and the lamp body 90.

[0147] Among them, the melting connection area 91a serves as the connecting part between the lamp body 90 and the screw 92. The melting connection area 91a partially melts when heated to adapt to the shape of the screw 92. The combination of the melting connection area 91a and the screw 92 ensures the connection strength of the screw 92 relative to the lamp body 90. At the same time, the screw 92 is subjected to connecting forces in multiple directions in the melting connection area 91a, thereby ensuring the connection stability of the screw 92 relative to the lamp body 90.

[0148] Furthermore, the lamp body 90 is a plastic part, and the lamp body 90 melts when exposed to heat, so that the lamp body 90 softened at high temperature can wrap the head of the screw 92. After the lamp body 90 cools down, it shrinks and forms an integrated structure with the screw 92, so that the screw 92 is integrally connected to the lamp body 90, ensuring the connection stability between the screw 92 and the lamp body 90.

[0149] Therefore, the melting connection area 91a partially melts when heated to adapt to the shape of the screw 92. The combination of the melting connection area 91a and the screw 92 ensures the connection strength of the screw 92 relative to the lamp body 90. At the same time, the screw 92 is subjected to connection forces in multiple directions in the melting connection area 91a, and the connection stability is strong.

[0150] Please refer to the attached Figures 17-18 In the embodiment of the present application, the melting connection area 91a is arranged on the backlight side of the lamp body 90. In addition, the melting connection area 91a is provided with a groove 91b, the size of which is adapted to the size of the head of the screw 92, so as to cover and limit the movement of the head of the screw 92; the head of the screw 92 is restricted by the lamp body 90 in different directions, so that the melting connection area 91a wraps the head of the screw 92 through the inner side wall of the groove 91b, thereby preventing the screw 92 from moving relative to the lamp body 90. At the same time, the head of the screw 92 is squeezed by the inner side wall of the groove 91b in all directions, so as to limit the head of the screw 92 in multiple directions, thereby controlling the connection stability between the head of the screw 92 and the melting connection area 91a, and ensuring the connection strength between the screw 92 and the lamp body 90.

[0151] In the first embodiment, the vehicle frame 1 is provided with a through hole, and the screw 92 is passed through the through hole, so that the screw 92 can be connected relative to the vehicle frame 1 through the through hole; at this time, the screw 92 is passed through the through hole along the axial direction of the through hole, so that the screw 92 can be connected to the vehicle frame 1 through the nut 93, and fixed to the vehicle frame 1, thereby ensuring the connection effect of the vehicle frame 1 and the lamp body 90.

[0152] At this time, a gasket 95 is provided between the rear side wall of the lamp body 90 and the front side wall of the frame 1, and the screw 92 is passed through the gasket 95, and the distance between the lamp body 90 and the frame 1 is adjusted, so that the distance between the lamp body 90 and the frame 1 can be adjusted by adding the gasket 95, thereby facilitating the adjustment of the position of the lamp body 90 relative to the frame 1, and thus adapting to different assembly scenarios. Optionally, the gasket 95 is arranged in a circular shape and has a certain thickness. Based on the thickness of the gasket 95 and the number of the gaskets 95, the distance between the rear side wall of the lamp body 90 and the front side wall of the frame 1 is controlled, thereby controlling the relative position of the lamp body 90 relative to the frame 1.

[0153] Please refer to the attached Figures 17-18 In the first embodiment, the lamp body module 20 is further provided with a nut 93, which is arranged on the side of the frame 1 facing away from the lamp body 90 and is screwed to the screw 92 to clamp the frame 1, so that the nut 93 is combined with the lamp body 90 to limit the position of the frame 1, so as to facilitate the position restriction after adjusting the distance between the lamp body 90 and the frame 1. Optionally, the nut 93 is located on the side of the frame 1 away from the lamp body 90, and the nut 93 is connected to the internal thread of the screw 21. The relative distance of the nut 93 relative to the frame 1 is controlled by rotating the nut 93, so that the frame 1 is approached and squeezed by the nut 93, so that the frame 1 is squeezed based on the nut 93, the gasket 95 and the lamp body 90, so as to achieve the fixation of the frame 1, thereby ensuring the connection effect and connection stability between the frame 1 and the lamp body 90.

[0154] Optionally, there are multiple gaskets 95, the screw 92 is passed through the multiple gaskets 95, and the multiple gaskets 95 are arranged in sequence along the axial direction of the screw 92. By arranging multiple gaskets 95, the distance between the lamp body 90 and the frame 1 is increased, thereby improving the adjustment range of the lamp body 90 relative to the frame 1. At this time, the gasket 95 has a certain thickness, and the distance between the rear side wall of the lamp body 90 and the front side wall of the frame 1 is controlled based on the thickness of the gasket 95 and the number of the gaskets 95, thereby controlling the relative position of the lamp body 90 relative to the frame 1.

[0155] Please refer to the attached Figures 17-18In the first embodiment, the lamp body module 20 also includes a sealing sponge 94, which is located between the rear side wall of the lamp body 90 and the front side wall of the frame 1 and covers the connection between the screw 92 and the lamp body 90. The sealing sponge 94 is sealed and connected to the lamp body 90 under the extrusion of the frame 1, so that the connection between the screw 92 and the lamp body 90 is sealed by the sealing sponge 94, preventing liquid from entering the lamp body 90 through the connection between the screw 92 and the lamp body 90, thereby ensuring the performance of the lighting components in the lamp body 90.

[0156] At this time, the sealing sponge 94 serves as a seal between the rear side wall of the lamp body 90 and the front side wall of the vehicle frame 1 , and seals the connection between the screw 92 and the lamp body 90 , while ensuring the connection stability between the screw 92 and the lamp body 90 .

[0157] In the second embodiment, the frame 1 is provided with an internal thread, the screw 92 is screwed into the internal thread, and the connection position of the screw 92 and the internal thread is adjusted as the screw 92 rotates, so that the screw 92 can be connected to the internal thread to adjust the distance relative to the frame 1, thereby adjusting the distance of the lamp body 90 relative to the frame 1 to adapt to different assembly scenarios.

[0158] In the present application, the screw 92 is connected to the lamp body 90 and is an integrated connection structure with the lamp body 90, so as to ensure the connection stability between the screw 92 and the lamp body 90, thereby facilitating the improvement of the hardness of the connection between the screw 92 and the lamp body 90; the screw 92 is connected to the frame 1 and is adjusted relative to the frame 1 to adjust the distance between the lamp body 90 and the frame 1, thereby adapting to different assembly scenarios, and ensuring the versatility of the lamp body module 20 relative to the frame 1.

[0159] At the same time, the melt connection area 91a serves as the connecting part between the lamp body 90 and the screw 92. The melt connection area 91a partially melts when heated to adapt to the shape of the screw 92. The melt connection area 91a, in combination with the screw 92, ensures the connection strength of the screw 92 relative to the lamp body 90. At the same time, the screw 92 is subjected to connecting forces in multiple directions in the melt connection area 91a, thereby ensuring the connection stability of the screw 92 relative to the lamp body 90.

[0160] Furthermore, the melting connection area 91a partially melts when heated to adapt to the shape of the screw 92. The melting connection area 91a ensures the connection strength of the screw 92 relative to the lamp body 90. At the same time, the screw 92 is subjected to connection forces in multiple directions in the melting connection area 91a, and has strong stability.

[0161] The melting connection area 91a is provided with a groove 91b, the size of which is adapted to the size of the head of the screw 92; the head of the screw 92 is restricted by the lamp body 90 in different directions, so that the melting connection area 91a wraps the head of the screw 92 through the inner wall of the groove 91b, and the head of the screw 92 is squeezed by the inner wall of the groove 91b in all directions, so that the head of the screw 92 is restricted in multiple directions, thereby ensuring the connection strength between the screw 92 and the lamp body 90.

[0162] There are multiple gaskets 95, and the screw 92 is passed through the multiple gaskets 95. The multiple gaskets 95 are arranged in sequence along the axial direction of the screw 92. By arranging multiple gaskets 95, the distance between the lamp body 90 and the frame 1 is increased, and the adjustment range of the lamp body 90 relative to the frame 1 is improved. At this time, the gasket 95 has a certain thickness. Based on the thickness of the gasket 95 and the number of the gaskets 95, the distance between the rear side wall of the lamp body 90 and the front side wall of the frame 1 is controlled, thereby controlling the relative position of the lamp body 90 relative to the frame 1.

[0163] It is worth noting that the light distribution mirror of the through-lamp is very large, and the flip-down mold method is very difficult to operate. If the mold is installed upright, the gate on the exterior is easily visible, which directly affects the exquisiteness of the entire vehicle. To solve this problem, many gates are currently reserved in front of the functional area. The light and shadow formed after the light hits its surface will affect the light type effect, and the display area will be obviously abrupt. For this purpose, please refer to the attached Figure 19-20 In the embodiment, a cover part 300 is designed to be embedded in the light distribution mirror 91, and the cover part 300 is connected to the light distribution mirror 91 and covers the gate part 21 of the light distribution mirror 91, so that the light distribution mirror 91 covers the gate part 21 through the cover part 300, thereby covering the gate part 21 of the light distribution mirror 91, preventing the gate of the light distribution mirror 91 from being exposed to the external environment, and improving the aesthetics of the light distribution mirror assembly 100. The cover part 300 can be in the shape of a cover strip or a cover block, etc., which is not limited here.

[0164] Please refer to the attached Fig.19 In the embodiment of the present application, the light distribution mirror 91 is provided with a gate portion 21 and a groove 91-1; the groove 91-1 is recessed from the outside to the inside of the light distribution mirror 91, and the notch of the groove 91-1 faces left ( Fig.19 The gate portion 21 is disposed on the inner side wall of the groove 91 - 1 ; the cover portion 300 is accommodated in the groove 91 - 1 , so that the cover portion 300 is fixed to the light distribution mirror 91 through the groove 91 - 1 .

[0165] At this time, the covering portion 300 is accommodated in the groove 91-1, making full use of the space of the groove 91-1. At the same time, the groove 91-1 is formed by the depression of the front side wall of the light distribution mirror 91, and the gate portion 21 is located on the inner side wall of the groove 91-1. The covering portion 300 covers the gate portion 21 while accommodating the groove 91-1, and the covering portion 300 does not exceed the notch of the accommodating groove 91-1, so that the outer side wall of the covering portion 300 and the front side wall of the light distribution mirror 91 form an overall smooth outer surface.

[0166] Please refer to the attached Fig.19 At this time, a connecting portion 22 is provided on the inner wall of the groove 91 - 1 , and the connecting portion 22 and the gate portion 21 are both located on the inner wall of the groove 91 - 1 ; the covering portion 300 is connected to the connecting portion 22 , so that the covering portion 300 can be fixedly connected to the light distribution mirror 91 through the connecting portion 22 .

[0167] At this time, the connecting portion 22 and the gate portion 21 are both on the inner wall of the groove 91-1, and the connecting portion 22 and the gate portion 21 are staggered. When the covering portion 300 is connected to the light distribution mirror 91, the covering portion 300 covers the connecting portion 22 and the gate portion 21 at the same time, so as to hide the connecting portion 22 and the gate portion 21 in the groove 91-1, thereby ensuring the appearance effect of the light distribution mirror 91.

[0168] Please refer to the attached Figure 19-21 In an embodiment of the present application, a support frame 400 is provided between the cover portion 300 and the photometric lens 91, the support frame 400 is located between the cover portion 300 and the photometric lens 91, the support frame 400 is connected to the connecting portion 22, the cover portion 300 is located on a side of the support frame 400 away from the connecting portion 22, and supports the cover portion 300, so that the cover portion 300 is fixedly connected to the connecting portion 22 through the support frame 400, thereby ensuring the stability of the cover portion 300 relative to the photometric lens 91.

[0169] At this time, the support frame 400 serves as a connecting piece between the cover portion 300 and the light distribution lens 91. The support frame 400 is connected to the light distribution lens 91 and supports the cover portion 300, thereby completing an indirect connection between the cover portion 300 and the light distribution lens 91; optionally, the support frame 400 can also serve as a part of the cover portion 300, and the support frame 400 is integrally connected to the cover portion 300, and a direct connection between the cover portion 300 and the light distribution lens 91 is achieved through the support frame 400, which is not limited here.

[0170] Please refer to the attached Figure 19-21At this time, the support frame 400 is detachably connected to the connecting portion 22 and is accommodated in the groove 91-1, so that the support frame 400 can be connected to or detached from the connecting portion 22. When the support frame 400 is connected to the connecting portion 22, the covering portion 300 covers the gate portion 21 as the support frame 400 is connected; when the support frame 400 is detached from the connecting portion 22, the covering portion 300 is opened as the support frame 400 is detached, so as to optimize the gate portion 21.

[0171] At this time, the support frame 400 is detachably connected to the connecting part 22 and can be connected to or detached from the connecting part 22. When the support frame 400 is connected to the connecting part 22, the support frame 400 is accommodated in the groove 91-1 and fully utilizes the internal space of the groove 91-1. At the same time, the support frame 400 extends along the length direction or width direction of the groove 91-1 to expand the supporting area of ​​the support frame 400 and support the covering part 300 through the support frame 400; moreover, the support frame 400 and the covering part 300 jointly perform multiple coverings on the gate part 21, thereby realizing a hidden closed design of the gate part 21.

[0172] Please refer to the attached Figure 19-21 , wherein the connecting portion 22 is a threaded hole; the support frame 400 is provided with a through hole 40a, and the through hole 40a is used for screws to pass through. The screws pass through the through hole 40a and are screwed to the threaded hole, so that the support frame 400 can be detachably connected to the connecting portion 22 through the screws and the threaded holes, thereby facilitating the support frame 400 to be connected to or detached from the connecting portion 22, and further facilitating the covering portion 300 to cover or open the gate portion 21. When the covering portion 300 covers the gate portion 21, the gate portion 21 of the light distribution lens 91 is covered.

[0173] Specifically, a boss portion is protruding from the inner wall of the groove 91-1, and the connecting portion 22 is opened on the boss portion and extends along the axis of the boss portion. Therefore, a threaded hole is opened on the boss portion, and a screw passes through the through hole 40a of the support frame 400 and is screwed to the threaded hole so that the support frame 400 can be squeezed through the head of the screw and the surface of the boss portion, thereby ensuring the connection effect between the support frame 400 and the photometric lens 91. At the same time, the separation effect of the support frame 400 and the photometric lens 91 can be achieved by rotating the screw.

[0174] Please refer to the attached Figure 19-21 In addition, the cover part 300 is located on the side of the support frame 400 away from the connection part 22, and the cover part 300 is detachably connected to the support frame 400, so that the cover part 300 can be connected to or separated from the support frame 400. When the cover part 300 is worn by the outer layer, the cover part 300 can be separated from the support frame 400, and then a new cover part 300 can be reinstalled on the support frame 400, so that the cover part 300 can be replaced.

[0175] Please refer to the attached Figure 19-21 Furthermore, the cover part 300 is snap-connected with the support frame 400, so that the cover part 300 can be detachably connected to the support frame 400 by snap-connection, thereby facilitating the cover part 300 to be connected to or detached from the support frame 400.

[0176] Specifically, the covering portion 300 includes a covering body 31 and a snap-fit ​​arm 32; the supporting frame 400 is provided with a snap-fit ​​portion 41, and the snap-fit ​​portion 41 is snap-fitted with the snap-fit ​​arm 32. At this time, the snap-fit ​​arm 32 is connected to the covering body 31, and the snap-fit ​​portion 41 is snap-fitted with the snap-fit ​​arm 32, so that the covering body 31 is snap-fitted with the supporting frame 400 through the snap-fit ​​portion 41 and the snap-fit ​​arm 32, so that the covering body 31 is detachably connected to the supporting frame 400 through the snap-fit ​​connection, so that the covering body 31 can be connected to or detached from the supporting frame 400. When the covering body 31 is connected to the supporting frame 400, the covering body 31 seals the opening of the groove 91-1 and covers the gate portion 21.

[0177] Please refer to the attached Fig.21 The engaging arm 32 has an elastic effect, so that the engaging arm 32 is engaged with the engaging portion 41 under the elastic effect, and the outer wall of the engaging arm 32 squeezes the inner wall of the engaging portion 41, thereby improving the engagement stability between the engaging arm 32 and the engaging portion 41. Specifically, the cover 30 is an elastic plastic part, and the engaging arm 32 is arranged obliquely relative to the cover body 31. The engaging arm 32 has an elastic effect and is elastically engaged with the engaging portion 41 when inserted into the engaging portion 41, thereby improving the engagement stability between the engaging arm 32 and the engaging portion 41.

[0178] Furthermore, a barb is provided at the end of the locking arm 32. When locked, the barb is located on the side of the locking portion 41 away from the covering body 31, and the barb abuts against the side of the locking portion 41 away from the covering body 31, thereby being restricted by the locking portion 41, preventing the locking arm 32 from moving toward the notch of the groove 10a and separating from the locking portion 41, thereby ensuring the locking stability between the locking arm 32 and the locking portion 41.

[0179] Another aspect of the present application provides a vehicle, including a tailgate, wherein the tailgate is provided with a lighting structure.

[0180] The through-light is usually embedded in the trunk lid of the vehicle's tailgate. Due to the design requirements, the surface of the through-light may be lower than the surface of the trunk lid, so it is easy for water to accumulate on the surface of the through-light's light distribution mirror when it rains or when washing the car. When the trunk lid is opened upward, the through-light also changes space, and the rainwater or cleaning fluid on the surface will flow into the trunk under the action of gravity, affecting normal use.

[0181] In order to solve the above technical problems, the trunk lid of the tailgate provided in the embodiment of the present application includes a water retaining assembly, and water retaining parts are respectively arranged at the opposite ends of the tailgate through groove, so that the through groove and the two water retaining parts cooperate to form an accommodating space, and the liquid can be retained in the accommodating space. When the trunk lid is opened, the liquid will be restricted by the two water retaining parts and will not leak into the trunk due to gravity flow; the water retaining parts are fixed at both ends of the through groove by a connecting structure, so that the water retaining part abuts against the abutting surface, and the two are tightly overlapped to prevent the liquid from flowing out from between the water retaining part and the abutting surface; in addition, the surface of the water retaining part away from the main body and close to the abutting surface is pressed against the abutting surface, that is, the side surface of the water retaining part in the thickness direction abuts against the abutting surface. In this way, the water retaining part will have a larger contact surface with the abutting surface, and the fit between the water retaining part and the abutting surface will be better. This is explained in detail below.

[0182] See also Fig. 22 , Fig.23 and Fig. 27 In one embodiment, the water retaining assembly includes a base 1 and a water retaining member 2. A through groove 1-1 is provided on the base 1. The water retaining member 2 is fixedly arranged at the opposite ends of the through groove 1-1 through a connecting structure. The two water retaining members 2 and the through groove 1-1 together enclose a accommodating space 3. The liquid can be temporarily stored in the accommodating space 3. When the trunk lid is opened and the liquid flows disorderly along the surface of the lens under the action of gravity, the liquid will be restricted by the two water retaining members and will not leak out of the accommodating space 3 and flow into the trunk due to gravity.

[0183] For ease of explanation, the base 1 involved in the following embodiments is a vehicle tailgate, and in some embodiments it can also be set in other forms, not limited to this; a through groove 1-1 is provided on the vehicle tailgate, and the through groove 1-1 can be used for the installation of components such as car lights. When the vehicle tailgate (base 1) is in a closed state, the opening of the accommodating space 3 (the opening opposite to the bottom of the through groove 1-1, the same below) faces the rear side (i.e. the rear side of the vehicle). When the vehicle tailgate is opened, the opening of the accommodating space 3 faces upward (i.e. above the vehicle), and the liquid will gather in the accommodating space 3 under the action of gravity. If the water retaining member 2 is not provided, the liquid will flow from the through groove 1-1 to both sides of the vehicle to the inside of the luggage compartment.

[0184] In some embodiments, the through slot 1-1 is not only Fig. 22 The horizontal setting shown is determined by the shape design of the tailgate, but is not limited to this.

[0185] In this embodiment, the base 1 (vehicle tailgate) has an abutment surface 1-2 facing the water retaining member 2, and the water retaining member 2 includes a main body 2-1 and a water retaining portion 2-2. The water retaining portion 2-2 is arranged on the side of the main body 2-1, and one end of the water retaining portion 2-2 away from the main body 2-1 abuts on the abutment surface 1-2. Through the setting of the connecting structure, the water retaining portion 2-2 is closely fitted with the abutment surface 1-2, thereby preventing the liquid flowing into the accommodating space 3 from flowing out from between the water retaining portion 2-2 and the abutment surface 1-2; at the same time, a part of the surface of the water retaining portion 2-2 away from the main body 2-1 and close to the abutment surface 1-2 is pressed against the abutment surface 1-2 (such as Fig. 27 As shown), that is, after the water retaining member 2 is fixed at both ends of the through groove 1-1 through the connecting structure, the side surface of the water retaining portion 2-2 in the thickness direction (as shown Fig. 27 As shown, the surface where the water retaining portion 2-2 contacts the abutting surface 1-2 (the same below) abuts against the abutting surface 1-2. Such an arrangement can effectively increase the contact area between the water retaining portion 2-2 and the abutting surface 1-2, and the fit between the water retaining portion 2-2 and the abutting surface 1-2 will be better, further preventing the liquid flowing into the accommodating space 3 from flowing out from between the water retaining portion 2-2 and the abutting surface 1-2.

[0186] It should be noted that the abutment surface 1-2 is the lateral direction of the through groove 1-1 ( Fig. 22 The plane around the opening of the substrate 1 (viewing angle) abuts against the water retaining portion 2-2, thereby preventing liquid from flowing out from between the water retaining portion 2-2 and the abutting surface 1-2; the shape of the abutting surface 1-2 is determined according to the specific design of the base 1, and the water retaining portion 2-2 is adapted to the abutting surface 1-2 accordingly.

[0187] See also Fig.24In one embodiment, the water retaining portion 2-2 has a plurality of elastic sub-portions 2-21 and a connecting sub-portion 2-22 connected between two adjacent elastic sub-portions 2-21. In this embodiment, four elastic sub-portions 2-21 are provided; when the water retaining member 2 is installed through the connecting structure, the elastic sub-portion 2-21 is pressed against the abutting surface 1-2, and a force toward the abutting surface 1-2 is applied to the abutting surface 1-2, that is, the elastic sub-portion 2-21 is deformed under pressure, and under the action of the elasticity of the elastic sub-portion 2-21 itself, the elastic sub-portion 2-21 fits more closely with the abutting surface 1-2, thereby improving the water retaining performance; when the water retaining member 2 is installed through the connecting structure, the connecting sub-portion 2-22 is just fitted against the corresponding abutting surface 1-2, that is, no interaction force is generated between the connecting sub-portion 2-22 and the abutting surface 1-2. With such arrangement, after the connecting sub-portion 2-22 is fitted with the abutting surface 1-2, no wrinkles (i.e. no gap) will be generated at the junction between the connecting sub-portion 2-22 and the elastic sub-portion 2-21; when the connecting sub-portion 2-22 is the same as the elastic sub-portion 2-21 (there is an interactive abutting pressure between the connecting sub-portion 2-22 and the abutting surface 1-2), wrinkles (gap) will easily be generated at the junction between the connecting sub-portion 2-22 and the elastic sub-portion 2-21, and liquid will flow out from the wrinkles.

[0188] For the sake of convenience, in this embodiment, the connection structure includes a connection seat 5 and a connection head adapted to the connection seat 5. The connection seat 5 is arranged on the surface of the main body 2-1 facing the through groove 1-1, and the connection head is arranged on the end surface of the lamp body arranged in the through groove 1-1 facing the main body 2-1 (not shown in the figure). When installing the water retaining member 2, it is only necessary to move the water retaining member 2 along the length direction of the through groove 1-1. Specifically, the water retaining member 2 is moved toward the car light in the through groove 1-1. During the movement, the end of the elastic sub-portion 2-21 away from the main body 2-1 contacts the corresponding abutting surface 1-2, and then Move the water retaining member 2. At this time, the elastic sub-portion 2-21 is deformed due to the pressure. The elastic sub-portion 2-21 fits tightly with the abutting surface 1-2. The side surface of the elastic sub-portion 2-21 in the thickness direction contacts with the abutting surface 1-2, which increases the contact area and effectively improves the water retaining performance. Continue to move the water retaining member 2 until the connecting head is inserted into the connecting seat 5. At this time, the position of the water retaining member 2 is fixed, and the connecting sub-portion 2-22 contacts with the corresponding abutting surface 1-2. The abutting surface 1-2 does not apply force to the connecting sub-portion 2-22 to deform it, that is, no wrinkles will be generated at the junction of the connecting sub-portion 2-22 and the elastic sub-portion 2-21.

[0189] In some embodiments, the relative position between the water retaining member 2 and the base 1 can be adjusted by controlling the height of the connecting seat 5, thereby achieving control over the deformation of the elastic sub-part 2-21; in other embodiments, the arrangement positions of the connecting head and the connecting seat 5 can also be other forms of settings, for example, the connecting seat 5 is set on the main body 2-1, and the connecting head is set on the base 1, but it is not limited to this and is designed according to actual installation requirements.

[0190] See also Fig. 27 In one embodiment, the water retaining portion 2-2 has an abutting sub-portion 2-23, a transition sub-portion 2-24 and a fixed sub-portion 2-25, the transition sub-portion 2-24 is connected between the abutting sub-portion 2-23 and the fixed sub-portion 2-25, the fixed sub-portion 2-25 is fixed to the main body 2-1 through a fixing structure 4, and the abutting sub-portion 2-23 abuts against the abutting surface 1-2 to form a barrier to the liquid; the width of the abutting portion between the abutting sub-portion 2-23 and the abutting surface 1-2 is W mm, satisfying: 2≤W≤10, for example, 2, 3, 4, 5, 6, 7, 8, 9, 10, etc.; when the value of W is less than 2, the contact area between the abutting sub-portion 2-23 and the abutting surface 1-2 is too small, the water retaining performance is poor, and the liquid in the accommodating space 3 is easy to flow from the abutting sub-portion 2-23 to the abutting surface 1-2 When W is greater than 10, the part of the abutting sub-portion 2-23 close to the transition sub-portion 2-24 fits more closely with the abutting surface 1-2 under the action of the transition sub-portion 2-24. On the contrary, at the end of the abutting sub-portion 2-23 far away from the transition sub-portion 2-24, due to the excessively large value of W, the fit between the end of the abutting sub-portion 2-23 far away from the transition sub-portion 2-24 and the abutting surface 1-2 becomes loose as W increases, resulting in poor water-blocking performance, wasting production materials, and increasing production costs. In addition, when W is too large, it is not conducive to the arrangement and connection of other components. It has been verified that when 2≤W≤10, it can not only ensure the close fit between the abutting sub-portion 2-23 and the abutting surface 1-2, thereby improving the water-blocking performance, but also avoid the waste of production materials and reduce production costs.

[0191] See also Fig. 27In one embodiment, the transition sub-portion 2-24 is arranged in an arc shape, and the fillet radius of the transition sub-portion 2-24 is R㎜, which satisfies: 5≤R≤20, such as 5, 10, 15, 20, etc.; the transition sub-portion 2-24 is arranged in an arc shape, which is conducive to the deformation of the abutting sub-portion 2-23 after contact with the abutting surface 1-2, that is, it is conducive to the close fit between the abutting sub-portion 2-23 and the abutting surface 1-2; when the value of R is less than 5, the arc length of the transition sub-portion 2-24 is short, and the transition between the fixed sub-portion 2-25 and the abutting sub-portion 2-23 is not smooth, which is not conducive to the direct fit between the abutting sub-portion 2-23 and the abutting surface 1-2, and the abutting sub-portion 2-2 When 3 is in contact with the abutting surface 1-2, the abutting sub-part 2-23 exerts a greater force on the abutting surface 1-2, that is, the reaction force of the abutting surface 1-2 on the abutting sub-part 2-23 is greater. In some embodiments, the connecting head is easy to pop out from the connecting seat 5, which is not conducive to the stability of the structure; when the value of R is greater than 20, more materials are required to process the water retaining part 2-2, which increases the production cost; it has been verified that when 5≤R≤20, the transition between the fixed sub-part 2-25 and the abutting sub-part 2-23 is smooth, which can not only ensure a better fit between the abutting sub-part 2-23 and the abutting surface 1-2 and improve the water retaining performance, but also save production materials and reduce production costs.

[0192] See also Fig. 27 In one embodiment, the minimum thickness of the abutting sub-portion 2-23 is h1㎜, satisfying: 1≤h1≤1.5, for example, 1, 1.2, 1.3, 1.5, etc. When the value of h1 is less than 1, the abutting sub-portion 2-23 is too thin, which is not conducive to the tightness of the fit between the abutting sub-portion 2-23 and the abutting surface 1-2, and is prone to water leakage; when the value of h1 is greater than 1.5, the abutting sub-portion 2-23 is too thick, and abutting the abutting sub-portion 2-23 against the abutting surface 1-2 requires a large force to overcome the elastic force generated by the deformation of the abutting sub-portion 2-23 itself. In some embodiments, the connecting head is easy to pop out of the connecting seat 5, which is not conducive to the stability of the structure; it has been verified that when 1≤h1≤1.5, it can not only ensure that the abutting sub-portion 2-23 is better deformed to fit closely with the abutting surface 1-2, but also avoid excessive elastic force when the abutting sub-portion 2-23 is deformed.

[0193] See also Fig. 27 In one embodiment, the maximum thickness of the transition sub-section 2-24 is h2㎜, satisfying: 2≤h2≤3, for example 2, 2.5, 3, etc.; when the value of h2 is less than 2, the transition sub-section 2-24 is too thin, and the support for the abutment sub-section 2-23 is insufficient (the abutment sub-section 2-23 cannot be pressed well onto the abutment surface 1-2); when the value of h2 is greater than 3, production materials are wasted and production costs are increased; it has been verified that when 2≤h2≤3, both the support for the abutment sub-section 2-23 can be guaranteed and the production cost can be saved.

[0194] See also Fig.25 and Fig.26In one embodiment, the fixing structure 4 includes fixing holes 4-1 arranged at intervals and fixing protrusions 4-2 adapted to the fixing holes 4-1, and the fixing protrusions 4-2 are inserted into the fixing holes 4-1; in this embodiment, the fixing holes 4-1 are arranged on the main body 2-1, and the fixing protrusions 4-2 are arranged on the water retaining part 2-2, which has a simple structure and reliable connection. In some embodiments, glue can also be applied on the contact surface of the main body 2-1 and the water retaining part 2-2 for bonding, but it is not limited to this.

[0195] The technical solution provided in the embodiment of the present application aims to respectively arrange water retaining members 2 at opposite ends of the through slot 1-1 of the tailgate of the vehicle, so that the through slot 1-1 cooperates with the two water retaining members 2 to form a containing space 3, and the liquid can be retained in the containing space 3. When the trunk lid is opened and the liquid flows disorderly along the surface of the light distribution mirror under the action of gravity, the liquid will be restricted by the two water retaining members and will not leak out of the containing space 3 due to gravity flow; the water retaining members 2 are fixed at both ends of the through slot 1-1 through a connecting structure , so that the water retaining part 2-2 abuts against the abutting surface 1-2, and the two are closely overlapped, which prevents liquid from flowing out from between the water retaining part 2-2 and the abutting surface 1-2; in addition, part of the surface of the water retaining part 2-2 away from the main body part 2-1 and close to the abutting surface 1-2 is pressed against the abutting surface 1-2, that is, the side surface of the water retaining part 2-2 in the thickness direction abuts against the abutting surface 1-2. In this way, the water retaining part 2-2 will have a larger contact area with the abutting surface 1-2, and the fit between the water retaining part 2-2 and the abutting surface 1-2 will be better.
