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] 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, affecting the light-guiding effect of the light-guiding component, and welding slag and welds will affect the overall appearance of the headlight.

[0003] In addition, based on the current styling and structural requirements of the entire vehicle, the shapes of automobile headlights are becoming more and more complex, and the overall size of the headlights is difficult to control, making the positioning space of the lamps smaller and smaller; the points used for positioning and installing headlights in the prior art occupy the already narrow space of the headlights, which is not conducive to the layout design of other components of the headlights, and the installation of the headlights is difficult. 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] A first light guide component is disposed in the accommodating cavity and has a light incident surface and a light emitting surface that are oppositely disposed, and a connecting surface connected between the light incident surface and the light emitting surface; and

[0009] A first decorative piece, fixed to the connecting surface via a first welding structure;

[0010] The first welding structure includes a first welding boss and a first welding leg, the first welding boss is arranged on the connecting surface, the first welding leg is arranged on the surface of the first decorative part facing the first light guide component, and the first welding leg is welded to the surface of the first welding boss.

[0011] On the other hand, the present application provides a vehicle, comprising the lamp structure.

[0012] The present application arranges a first welding boss on the connecting surface of the first light guiding component. The weld and welding slag after the first welding boss is welded to the first welding leg are controlled on the first welding boss. Since the first welding boss protrudes from the connecting surface, the weld and welding slag will not affect the conduction of light inside the first light guiding component, thereby effectively improving its light guiding effect.

[0054] 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.

[0055] 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.

[0056] 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.

[0057] 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.

[0058] 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 first light guide component and the second light guide component can be functional lights such as turn signals, position lights, brake lights, etc., which are not limited by the present application, and the details of the scheme will be elaborated in detail below.

[0059] See also Figure 2 and Figure 3 In 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 3In 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.

[0060] 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.

[0061] 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.

[0062] 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.

[0063] 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).

[0064] See also Figure 2 and Figure 3 In 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.

[0065] 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 3In 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.

[0066] See also Figure 2 and Figure 4 In 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.

[0067] 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 24 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.

[0068] 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.

[0069] 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.

[0070] 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 3The 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.

[0071] 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.

[0072] 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.

[0073] See also Figure 3The 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.

[0074] 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.

[0075] 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.

[0076] 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.

[0077] refer to Figure 6 and Figure 7 The light distribution lens 91 comprises:

[0078] The first light distribution component 910 includes a light entrance part 911 and a light exit part 912;

[0079] 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;

[0080] 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°.

[0081] 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.

[0082] 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.

[0083] 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 .

[0084] 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.

[0085] 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.

[0086] refer to Fig.10 In some embodiments, the surface of the light path adjustment surface 921a has a dermatoglyphic structure.

[0087] 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.

[0088] 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.

[0089] 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.

[0090] 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.

[0091] 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.

[0092] 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.

[0093] 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.

[0094] 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.

[0095] 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.

[0096] 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.

[0097] In the prior art, the points used for positioning and installing the headlights occupy the already narrow space of the headlights, which is not conducive to the layout design of other components of the headlights, and the installation of the headlights is difficult. Fig.11In one embodiment, the lamp includes a positioning structure 2, and the lamp body 90 is positioned and installed on the vehicle frame 4 through the positioning structure 2. The positioning structure 2 includes a plurality of connecting support legs 21 arranged at intervals. In this embodiment, the number of the connecting support legs 21 is four; the connecting support leg 21 has a supporting surface 213. When the lamp is installed on the frame 4, the supporting surface 213 fits with the frame 4, which can ensure the stability of the lamp during installation and effectively improve the assembly quality of the lamp; a connecting point 214 is provided on the supporting surface 213, and the connecting point 214 is used to connect with the frame 4. By using the fixing structure 3 to fix the connection with the frame 4 at the position of the connecting point 214, the orthographic projection of the connecting point 214 on the plane where the supporting surface 213 is located is located outside the orthographic projection of the lamp body 90 on the plane where the supporting surface 213 is located, that is, the connecting point 214 is arranged outside the range of the lamp body 90 ( Fig.11 With this arrangement, the connection point 214 will not occupy the space of the lamp body 90, nor will it interfere with the installation of related components on the lamp body 90; at the same time, the connection point 214 is arranged on the periphery of the lamp body 90, which facilitates the operation of the installer during installation and is beneficial to improving the assembly quality of the lamp.

[0098] By adopting the technical solution provided in the embodiment of the present application, on the plane where the supporting surface is located, by setting the orthographic projection of the connection point used for connecting to the frame outside the orthographic projection of the lamp body, it is possible to avoid the connection point occupying the space of the lamp, which is conducive to the diversified design of the lamp; and the orthographic projection of the connection point is outside the orthographic projection of the lamp body, which facilitates the installation operation of the lamp body on the frame, effectively improves the assembly quality of the lamp body, and ensures the stability of the lamp.

[0099] It should be noted that in this embodiment, the fixing structure 3 includes a fixing hole 31, a bolt 32 and a nut 33. The fixing hole 31 is set on the connecting support leg 21 where the support surface 213 is located. The nut 33 passes through the fixing hole 31 and then continues to pass through the frame 4 and is fastened by the nut 33 (such as Fig.13 As shown), the lamp is installed on the frame 4, with a simple structure and reliable connection. In some embodiments, other forms of fixed structures 3 may be used, but are not limited thereto, as long as a stable connection between the lamp and the frame 4 is ensured, and the stability of the lamp after connection is ensured.

[0100] See also Fig.11 , Fig.14 as well as Fig.16In one embodiment, the connecting support leg 21 includes a connecting portion 211 and a supporting portion 212. The connecting portion 211 is connected to the lamp body 90, and the supporting portion 212 is connected to an end of the connecting portion 211 away from the lamp body 90. That is, through the setting of the connecting portion 211, the supporting portion 212 is separated from the lamp body 90, and the supporting surface 213 is set on the supporting portion 212. Such an arrangement can keep the supporting surface 213 (that is, the connecting point 214) away from the lamp body 90, avoid interference between the supporting portion 212 and the lamp body 90, and facilitate installation operations.

[0101] It should be noted that, in the present embodiment, the connecting portion 211 and the supporting portion 212 are arranged in a plate shape, and a reinforcing rib (not marked in the figure) is arranged between the connecting portion 211 and the supporting portion 212 to strengthen the stability of the connection between the connecting portion 211 and the supporting portion 212, thereby improving the stability of the supporting portion 212. Under the action of external force, the supporting portion 212 is more likely to remain stationary relative to the lamp body 90, thereby improving the stability of the lamp installation; in addition, by spacing the supporting portion 212 from the lamp body 90, the orientation of each supporting portion 212 (in the present embodiment, the supporting portion 212 is in a plate shape, and the orientation is the direction perpendicular to the supporting surface 213, the same below) can be controlled to be consistent, thereby facilitating the installation of the lamp, and multiple supporting portions 212 (supporting surfaces 213) can be simultaneously fitted to the vehicle frame 4 along a predetermined direction, thereby improving the installation efficiency, and ensuring that the orientation of the supporting portion 212 is not restricted by the shape of the lamp itself, thereby improving the designability of the lamp. In some embodiments, multiple support portions 212 can also be arranged flush (that is, the support surfaces 213 of each support portion 212 are arranged coplanarly), and the design of the connecting portion 211 and the support portion 212 can be determined according to specific needs based on one or more factors such as the shape of the frame 4 (the shape for lamp assembly), the design shape of the lamp, and the positioning requirements of the lamp.

[0102] See also Fig.11 In one embodiment, the connecting portion 211 is arranged at the edge of the lamp body 90, so as to avoid the connecting portion 211 occupying the space of the lamp body 90, which is beneficial to the arrangement and installation of various components of the lamp. Such arrangement ensures that the supporting portion 212 does not occupy the space of the lamp body 90.

[0103] See also Fig.11 In one embodiment, the lamp body 90 has at least two side edges 90a. In this embodiment, there are three side edges 90a. An angle is formed between two adjacent side edges 90a and the three side edges 90a are connected end to end in sequence. The connecting support legs 21 are distributed on two adjacent side edges 90a. Such a configuration does not occupy the upper portion of the lamp body 90 ( Fig.11 The space (in the viewing angle) is beneficial to the design of the lamp body 90, can meet the vehicle styling requirements and structural requirements, and provides an operable space above the lamp body 90.

[0104] It should be noted that the number of side edges 90a is determined by the specific structure of the lamp body 90. In some embodiments, the number of side edges 90a can be four or any other number. The arrangement of the connecting support legs 21 meets the positioning requirements of the lamp and ensures the stability of the lamp body 90 after installation. In some embodiments, the side edges 90a have a positioning surface, and the positioning structure 2 also includes positioning pads 23 arranged at intervals on the positioning surface. In some embodiments, the positioning pads 23 can be embedded in the positioning surface or bonded to the positioning surface. When the connecting support legs 21 are arranged on part of the side edges 90a and cannot meet the positioning requirements of the lamp body 90, the positioning pads 23 can be arranged on the positioning surface to stabilize the lamp body 90, so that the lamp body 90 meets the DTS size definition requirements, thereby preventing the lamp body 90 from being deformed when the vehicle is in use, thereby affecting the appearance and use of the lamp. Fig.14 and Fig.16 As shown, three positioning pads 23 are arranged at intervals on the positioning surfaces on the two longer sides 90a of the lamp body 90 to stabilize the lamp body 90. It should also be noted that the vehicle frame 4 is provided with a mounting hole, and the lamp body 90 is embedded in the mounting hole. The positioning surface is the surface of the side 90a of the lamp body 90 that is opposite to the wall of the mounting hole when the lamp body 90 is embedded in the mounting hole. The positioning pads 23 are arranged between the wall of the mounting hole (the vehicle frame 4) and the positioning surface.

[0105] Among them, DTS (Dimensional Technical Specification) refers to the design requirements for the gaps and face differences between the various components of the interior and exterior of the vehicle. It is an important indicator of the manufacturing quality of the interior and exterior of the vehicle, and also reflects the manufacturing level of the dimensional quality of the vehicle. It defines the nominal values ​​of the gaps, face differences and fillets of the interior and exterior of the vehicle, and defines the tolerance control standards for each nominal value.

[0106] See also Fig.17 In one embodiment, the area of ​​the orthographic projection of the lamp body 90 on the plane where the support surface 213 is located is S1㎝2, and the area of ​​the orthographic projection of the connecting support leg 21 on the plane where the support surface 213 is located is S2㎝2, satisfying: S2 / S1<60%; in this embodiment, the number of connecting support legs 21 is N, where N is an integer greater than three, and in this embodiment, it is set to four. The proportion of the area can intuitively reflect that the connecting support leg 21 does not occupy the space of the lamp body 90, and can provide more installation positions for the other components of the lamp, provide more design space and design methods for each component, and facilitate the installation operation of each component; in addition, the connection support leg 21 is arranged below the lamp body 90 ( Fig.11 Perspective), the space above the lamp body 90 is not occupied. Therefore, the vehicle part above the lamp body 90 can have more design space, leaving more space for the entire vehicle, making the shape more maneuverable, while ensuring the size requirements of the lamp and meeting the yield of its own production.

[0107] It should be noted that, in some embodiments, the value of N can be five or six. Of course, the larger the value of N is, the better. The specific structure of the lamp body 90 needs to be considered. In addition, the impact of vibration, impact and other test items on the fixed structure 3 between the connecting support leg 21 and the frame 4 needs to be considered at the same time. The four connecting support legs 21 of the present application can meet the load requirements of various test items; and when N is greater than 4, the number is large, which will occupy more space around the lamp body 90, which is not conducive to the design and layout of other related components around it.

[0108] See also Fig.11 and Fig.15 In one embodiment, the lamp has a first direction X (eg Figure 14-16 The first direction X is perpendicular to the support surface 213, and the positioning structure 2 further includes latches 22 arranged at intervals, which extend along the first direction X. In the present embodiment, the first direction X is the front-rear direction of the vehicle. When the lamp is assembled, the lamp is moved toward the vehicle along the first direction X until the support surface 213 abuts against the frame 4. Before the support surface 213 abuts against the frame 4, due to the provision of the above-mentioned latch 22, the latch 22 preferentially contacts the latch hole 24 on the frame 4. When the lamp continues to move toward the vehicle, the latch 22 is gradually inserted into the latch hole 24 on the frame 4 until the support surface 213 abuts against the frame 4. Since two latches 22 are arranged at intervals, when the latch 22 is inserted into the latch hole 24, the up, down, left, right and rotation direction of the lamp can be limited. Fig.11 while being able to quickly locate the fixed position between the connection point 214 and the frame 4, thereby improving assembly efficiency.

[0109] It should be noted that, in some embodiments, before the fixing structure 3 is installed, in order to stabilize the lamp body 90 as much as possible, the latch 22 may be arranged at the leftmost and rightmost positions ( Fig.11 The latch 22 does not need an additional installation position and does not occupy the space of the lamp body 90. The latch 22 is arranged on the support surface 213 to ensure that the support surface 213 is fully fitted with the vehicle frame 4, thereby ensuring the assembly quality. In addition, in some embodiments, the first direction X can also be set in other directions, for example, the first direction X points from the main driving side to the co-driving side of the vehicle, etc. At this time, the assembly direction and the orientation of the support surface 213 will also change accordingly, and it is not limited thereto.

[0110] In one embodiment, in order to improve the limitation of the freedom of the lamp by the plug 22, the cross section of the plug 22 perpendicular to the first direction X can be cross-shaped, which can improve the limitation effect of the freedom of the lamp. In order to ensure that the plug 22 is smoothly inserted into the plug hole 24 on the frame 4, at the free end of the plug 22 (i.e., the end away from the lamp body 90) along the direction away from the lamp body 90, the cross-sectional area gradually decreases (such as Fig.15In some embodiments, the latch 22 may also be columnar, and the side wall of the latch 22 is provided with a limiting groove 221, which is matched with the limiting protrusion 241 provided on the wall of the latch hole 24. When the latch 22 is inserted, the limiting protrusion 241 falls into the limiting groove 221 to fix the latch 22 (as shown in FIG. Fig.12 shown), but not limited thereto.

[0111] See also Fig.11 and Fig.17 In one embodiment, the positioning structure 2 includes four connecting support legs 21 and two pins 22, and the two pins 22 are arranged on the supporting surface 213 of the connecting support legs 21, and six positioning pads 23 are arranged at intervals on the side 90a to assist in the positioning of the lamp; in this embodiment, S2=155㎝2, S1=320㎝2, S2 / S1=48%<60%, and the positioning method in this embodiment is analyzed through CAE model analysis, and the result is qualified and meets the DTS size definition requirements.

[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 18-Figure 20 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 18-Figure 20 The 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 18-Figure 20 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 19-21 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 19-21 , 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.19 It 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 19-21 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.
