Detailed Implementation

[0049] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0050] The specific technical features described in the specific embodiments can be combined in any suitable manner without contradiction. For example, different combinations of specific technical features can form different embodiments and technical solutions. To avoid unnecessary repetition, the various possible combinations of the specific technical features in this invention will not be described separately.

[0051] In the following description, the terms "first," "second," etc., are used merely to distinguish different objects and do not indicate that the objects have the sameness or relationship. It should be understood that the directional descriptions "above," "below," "outside," and "inside" refer to the orientation under normal use conditions, while "left" and "right" refer to the left and right directions shown in the corresponding diagrams, which may or may not be the left and right directions under normal use conditions.

[0052] It should be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element. "A plurality of" means two or more.

[0053] In the description of this application, the orientation or positional relationship of "first direction", "height direction" and "second direction" are based on the orientation or positional relationship shown in the accompanying drawings. The "first direction" is the direction indicated by arrow L1 in the accompanying drawings, the "height direction" is the direction indicated by arrow L2 in the accompanying drawings, and the second direction is the direction perpendicular to the paper of the accompanying drawings. It should be understood that these orientation terms are only for the convenience of describing this application and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0054] In this embodiment, the light guide structure is used to guide the light emitted by the light source to the light emission position. As an example, the light guide structure can be what is commonly referred to in the art as a thick-walled component for automotive lamps. Specifically, a thick-walled component for automotive lamps refers to a wall-shaped member made of a light-transmitting material, which is typically installed inside the lamp housing to improve the focusing and brightness of the light. Furthermore, the thick-walled component for automotive lamps also serves to protect the lamp light source and other structures.

[0055] It should be noted that, unless otherwise specified, the walls described below can be straight walls, curved walls, or walls of any other shape, as long as they can perform the relevant functions.

[0056] Reference Figure 1 and Figure 2 The light guide structure 1 includes an entrance wall 11, an exit wall 12 and at least two reflective walls 13. Light rays incident from the entrance wall 11 are reflected by the at least two reflective walls 13 to different regions of the exit wall 12, so as to form at least two exiting regions in the exit wall 12. The average light intensity of the at least two exiting regions is different.

[0057] In this embodiment, the specific number of reflective walls 13 is not limited. For example, there may be two, three, four or even more. Those skilled in the art can determine the specific number based on the actual desired number of light-emitting areas. The following description will mainly use two reflective walls 13 as an example.

[0058] The specific distribution of the light entrance wall 11, the light exit wall 12, and at least two reflective walls 13 is not limited, as long as the light incident on the light entrance wall 11 is reflected by at least two reflective walls 13 to different areas of the light exit wall 12.

[0059] Taking at least two reflective walls 13, including a first reflective wall 13a and a second reflective wall 13b, as an example, in order to achieve the above effect, a portion of the light rays incident on the incident light wall 11 needs to reach the first reflective wall 13a, and another portion of the light rays needs to reach the second reflective wall 13b.

[0060] As an example, light incident through the incident light wall 11 can be directly refracted onto the first reflective wall 13a and the second reflective wall 13b. By appropriately setting the positional relationship between the incident light wall 11 and the light source 2, as well as the shape of the incident light wall 11, a portion of the light is refracted onto the first reflective wall 13a, and another portion onto the second reflective wall 13b. Alternatively, there can be multiple incident light walls 11, with some refracting light onto the first reflective wall 13a and others onto the second reflective wall 13b. In these embodiments, during actual use, multiple incident light walls 11 can each correspond to multiple light sources 2, or they can share a single light source 2.

[0061] As another example, the light incident on the incident light wall 11 can be reflected to the first reflective wall 13a and the second reflective wall 13b via a reflective structure. This reflective structure can be an external reflector or other reflective walls of the light guide structure 1.

[0062] The first reflective wall 13a and the second reflective wall 13b can achieve a reflective effect through a reflective coating on their inner surfaces, or through a reflective texture structure on their inner surfaces; there is no limitation on which method is used. In order to maximize the utilization of light, the first reflective wall 13a and the second reflective wall 13b should be configured to perform total internal reflection as much as possible.

[0063] In this embodiment, the average light intensity of at least two light-emitting areas formed on the light-emitting wall 12 by the light reflected by at least two reflective walls 13 is different.

[0064] Taking the first reflective wall 13a forming a first light-emitting area 12a on the light-emitting wall 12 and the second reflective wall 13b forming a second light-emitting area 12b on the light-emitting wall 12 as an example, the average light intensity of the first light-emitting area 12a can be greater than that of the second light-emitting area 12b.

[0065] As an example, the average light intensity of the first light-emitting area 12a can be made greater than the average light intensity of the second light-emitting area 12b by making the incident light amount of the first reflective wall 13a greater than the incident light amount of the second reflective wall 13b. Here, the incident light amount should be understood as the amount of light per unit reflective area.

[0066] As another example, the average light intensity of the first light-emitting area 12a can be made greater than the average light intensity of the second light-emitting area 12b by making the light reflectance of the first reflective wall 13a greater than that of the second reflective wall 13b.

[0067] Either of the above two methods can achieve different average light intensities in the light-emitting areas. Those skilled in the art can choose one method or combine the two according to actual usage requirements. In comparison, achieving different average light intensities in the light-emitting areas by controlling the amount of incident light from each reflector 13 helps reduce light loss from the light source 2 and obtain better light emission effects. Furthermore, achieving different average light intensities in the light-emitting areas by controlling the light reflectance of each reflector 13 helps reduce costs and allows for more precise control of the average light intensity of each light-emitting area.

[0068] In this embodiment, at least two light-emitting areas with different light intensities can be formed on the light-emitting wall 12 of the light guide structure 1. This allows the light emitted by the vehicle headlights to have a sense of layering, improving the lighting effect. Furthermore, in this embodiment, the above effect can be achieved using the reflective wall 13 of the light guide structure 1 itself, resulting in a simple structure and low cost.

[0069] In some embodiments, along the distribution direction of at least two light-emitting zones, the average light intensity of each light-emitting zone gradually increases or gradually decreases. This light emission method can present a gradient light effect, which helps to further enhance the visual experience. Of course, in some other embodiments, along the distribution direction of at least two light-emitting zones, the average light intensity of each light-emitting zone may first increase and then decrease, or first decrease and then increase. Those skilled in the art can reasonably set the relationship between the average light intensities of each light-emitting zone according to the actual desired light emission effect.

[0070] In the above embodiments, the light intensity at different locations within the light-emitting area can be the same; that is, the light-emitting area itself only presents a uniform light-emitting effect, rather than a gradual light effect.

[0071] Alternatively, the light intensity at different locations within the light-emitting area can be different. More specifically, assuming that each light-emitting area is distributed along the height direction of the light guide structure, the light intensity at different locations within the light-emitting area along the height direction can gradually increase or gradually decrease. That is, each light-emitting area can present a gradient light effect together, and each light-emitting area can present a gradient light effect individually.

[0072] In some embodiments, Figure 1 and Figure 2 The light guide structure 1 includes a beam splitter 14, which reflects the light emitted by the light source 2 to at least two reflective walls 13. In this embodiment, the distribution of incident light is achieved by means of the beam splitter 14, thus eliminating the need for multiple light sources 2, multiple incident light walls 11, and / or external reflection structures to distribute light to at least two reflective walls 13, thereby further reducing the manufacturing and usage costs of the light guide structure 1.

[0073] In this embodiment, the effect of distributing light can be achieved by reasonably setting the position and angle of the beam splitter 14. As an example, the beam splitter 14 may include multiple reflective surfaces at different angles, each corresponding to a multiple reflective wall 13.

[0074] In some embodiments, the beam-splitting wall 14 is configured such that the incident light amounts of at least two reflective walls 13 are different. As mentioned above, this enables the average light intensity of the light-emitting areas corresponding to each reflective wall 13 to be different, and this implementation results in less light loss.

[0075] In some embodiments, at least two reflective walls 13 include a first reflective wall 13a and a second reflective wall 13b, and a beam-splitting wall 14 forms a total reflection zone and a diffuse reflection zone. The total reflection zone reflects light to the first reflective wall 13a, and the diffuse reflection zone reflects light to both the first reflective wall 13a and the second reflective wall 13b.

[0076] It is understood that the reflection efficiency of diffuse reflection is much lower than that of total internal reflection. Therefore, in this embodiment, the amount of incident light from the first reflective wall 13a and the second reflective wall 13b can be different.

[0077] In this embodiment, the specific formation and distribution of the total reflection area and the diffuse reflection area are not limited. Taking the formation of reflective patterns (such as scale-like reflective patterns well known to those skilled in the art) on the beam-splitting wall 14 as an example, the reflective patterns can have smooth parts and rough parts. The smooth parts will reflect light to the first reflective wall 13a (that is, the smooth parts form a total reflection area), and the rough parts will diffusely reflect light (that is, the rough parts form a diffuse reflection area).

[0078] It is understandable that when light undergoes diffuse reflection, the reflected light is directed in all directions. The diffuse reflection area can reflect light to the first reflective wall 13a and the second reflective wall 13b simultaneously. Furthermore, when there are more reflective walls 13, the diffuse reflection area can also reflect light to other reflective walls 13.

[0079] In this embodiment, both the beam-splitting wall 14 and the first reflective wall 13a can be straight walls. The beam-splitting wall 14 can be parallel to the first reflective wall 13a, or the angle between the extending directions of the beam-splitting wall 14 and the first reflective wall 13a can be less than or equal to 20°. In comparison, the parallel arrangement of the beam-splitting wall 14 and the first reflective wall 13a helps to control the angle of the emitted light from the light-emitting wall 12 (the emitted light from the light-emitting wall 12 will be parallel to the incident light from the beam-splitting wall 14). The angle between the extending directions of the beam-splitting wall 14 and the first reflective wall 13a being less than or equal to 20° helps to reduce manufacturing precision requirements and improve design flexibility.

[0080] In some other embodiments, still taking at least two reflective walls 13, including a first reflective wall 13a and a second reflective wall 13b, as an example, the beam-splitting wall 14 can form a first total internal reflection area and a second total internal reflection area. The first total internal reflection area reflects light to the first reflective wall 13a, and the second total internal reflection area reflects light to the second reflective wall 13b, thus achieving light distribution. It should be noted that when more reflective walls 13 are provided, more total internal reflection areas can be provided accordingly.

[0081] In this embodiment, the amount of incident light on the first reflective wall 13a and the second reflective wall 13b can be different by making the first total reflection area and the second total reflection area have different light reflectance ratios. Alternatively, the amount of incident light on the first reflective wall 13a and the second reflective wall 13b can be different by adjusting the positional relationship and area of ​​the first total reflection area and the second total reflection area. The advantage of this implementation is that the amount of incident light on each reflective wall 13 is controllable regardless of the number of reflective walls 13, which helps to achieve a more layered light emission effect.

[0082] In some embodiments, refer to Figure 1 and Figure 2 The light entrance wall 11 and the light exit wall 12 are distributed along the first direction and are staggered in the height direction. The first direction is perpendicular to the height direction.

[0083] As an example, when the light guide structure 1 is actually installed in a vehicle, the first direction is the front-to-back direction of the vehicle, and the height direction is the height direction of the vehicle.

[0084] The fact that the entrance wall 11 and the exit wall 12 are staggered in the height direction means that, in the projection plane perpendicular to the first direction, the projections of the entrance wall 11 and the exit wall 12 are spaced apart along the height direction.

[0085] The beam-splitting wall 14 and at least two reflective walls 13 are both disposed between the entrance wall 11 and the exit wall 12. Here, "the beam-splitting wall 14 and at least two reflective walls 13 are both disposed between the entrance wall 11 and the exit wall 12" means that, in a projection plane perpendicular to the height direction, the projection of the beam-splitting wall 14 and the projection of the at least two reflective walls 13 are assumed to be between the projection of the entrance wall 11 and the projection of the exit wall 12.

[0086] The beam-splitting wall 14 and the light-incident wall 11 are arranged opposite each other along the first direction, and at least two reflective walls 13 are arranged opposite each other to the light-outceasing wall 12 along the first direction.

[0087] The beam splitter 14 and the incident light wall 11 are arranged opposite each other along the first direction, meaning that in the projection plane perpendicular to the first direction, the projections of the beam splitter 14 and the incident light wall 11 at least partially overlap. For example, the projection of the beam splitter 14 completely covers the projection of the incident light wall 11.

[0088] The arrangement of at least two reflective walls 13 opposite to the light-emitting wall 12 along the first direction means that in the projection plane perpendicular to the first direction, the projection of each reflective wall 13 at least partially overlaps with the projection of the light-emitting wall 12. For example, the projection of the light-emitting wall 12 covers the projection of all the reflective walls 13.

[0089] In this embodiment, this distribution method helps to simplify the light guide structure 1, reduce the difficulty and cost of fabrication, and improve the light utilization rate.

[0090] In some embodiments, the top end of the light-emitting wall 12 is connected to the beam-splitting wall 14, and the light-emitting wall 12 extends obliquely away from the light-incident wall 11 along the direction from the top end to the bottom end. The advantage of the oblique extension of the light-emitting wall 12 is that, when applied to vehicles, it can improve the aesthetics of the headlights under natural light. Of course, in some other embodiments, the extension direction of the light-emitting wall 12 may also be parallel to the height direction.

[0091] In some embodiments, specifically, referring to Figure 1 The angle between the extension direction of the light-emitting wall 12 and the height direction is α1, where α1 is greater than 0° and less than or equal to 30°. α1 being less than or equal to 30° helps to reduce the wall thickness of the light guide structure 1, thereby reducing the difficulty of injection molding. As an example, α1 can be 2°, 5°, 10°, 12°, 15°, 18°, 20°, 22°, 25°, 28°, 30°, etc.

[0092] In some embodiments, refer to Figure 1 and Figure 2At least two reflective walls 13 are distributed along the height direction. As mentioned above, in actual use, the height direction is parallel to the height direction of the vehicle, thus achieving a gradient light effect along the vehicle's height direction.

[0093] In some other embodiments, at least two reflective walls 13 may also be distributed along a second direction, which is perpendicular to the first direction and the height direction, respectively (in... Figure 1 and Figure 2 In the text, the first direction is perpendicular to the paper. In actual use, the second direction can be parallel to the width of the vehicle. Those skilled in the art can determine the distribution of each reflector 13 according to actual usage requirements.

[0094] In some embodiments, refer to Figure 1 and Figure 2 The light guide structure 1 includes a first straight wall 15 and a second straight wall 16 disposed on the bottom side of the first straight wall 15, and both the first straight wall 15 and the second straight wall 16 extend along a first direction.

[0095] The two ends of the light-entry wall 11 along the height direction are respectively connected to the first straight wall 15 and the second straight wall 16.

[0096] The top end of the beam-splitting wall 14 is connected to one end of the first straight wall 15, and the bottom end is connected to the top end of the light-emitting wall 12. Specifically, one end of the beam-splitting wall 14 is connected to the end of the first straight wall 15 that is away from the light-incident wall 11.

[0097] At least two reflective walls 13 are distributed along the height direction, and one end of at least one reflective wall 13 is connected to one end of the second vertical wall 16, specifically, to the end of the second vertical wall 16 away from the light-incident wall 11. Furthermore, one end of at least one reflective wall 13 is connected to the bottom end of the light-outceasing wall 12.

[0098] Taking a reflective wall 13 comprising a first reflective wall 13a and a second reflective wall 13b, with the first reflective wall 13a and the second reflective wall 13b distributed along the height direction as an example, the bottom end of the first reflective wall 13a is connected to the light-emitting wall 12, and the top end is connected to the bottom end of the second reflective wall 13b. The top end of the second reflective wall 13b is connected to the end of the second straight wall 16 away from the light-incident wall 11. It can be understood that in an embodiment where the first reflective wall 13a and the second reflective wall 13b are distributed along a second direction, the opposite ends of the first reflective wall 13a can be connected to the light-emitting wall 12 and the second straight wall 16, and the opposite ends of the third reflective wall 13 are also connected in this way.

[0099] In this embodiment, a first straight wall 15 and a second straight wall 16 are provided between the light entrance wall 11 and the beam splitter wall 14. This increases the travel distance of the light from the light entrance wall 11 to the beam splitter wall 14, thereby allowing the light to be better focused on the beam splitter wall 14 and thus achieving a better light output effect.

[0100] On the other hand, the first straight wall 15 and the second straight wall 16 can also be used to fix the optical guide structure 3 during actual use, thereby improving the installation stability of the optical guide structure 1. As an example, in some embodiments, at least one of the first straight wall 15 and the second straight wall 16 has at least one protrusion 16a formed on the side surface facing away from the other, and the protrusion 16a is used to connect with the external mounting structure 3.

[0101] In some embodiments, the distance between the light-incident wall 11 and the light-outcident wall 12 is not less than 25 mm. This distance range helps to better improve the light focusing effect.

[0102] In some embodiments, along the direction from the incident light wall 11 to the beam-splitting wall 14, the second vertical wall 16 extends beyond the first vertical wall 15. This helps to ensure that the reflective surface of the beam-splitting wall 14 can cover the entire reflective wall 13.

[0103] It is understood that in order for light to be reflected from the beam-splitting wall 14 to the reflector wall 13, and then reflected a second time to the light-emitting wall 12, the beam-splitting wall 14 and the reflector wall 13 need to be tilted relative to the light-emitting wall 12. This tilt angle can be specifically determined by those skilled in the art based on actual usage requirements and manufacturing processes.

[0104] Taking a reflective wall 13 comprising a first reflective wall 13a and a second reflective wall 13b along the height direction, with the first reflective wall 13a connected to the light-emitting wall 12 and the second reflective wall 13b connected to the second vertical wall 16 as an example, refer to... Figure 1 The dimension of the first reflective wall 13a along the height direction is D1. The distance between the end of the first reflective wall 13a away from the light-emitting wall 12 and the light-emitting wall 12 is D2. The angle between the light-emitting wall 12 and the height direction is α1, and the angle between the second reflective wall 13b and the first direction is α2. In the actual design process, D1 can be specifically determined according to the actual size requirements of the first light-emitting area 12a, the value of D2 can be specifically determined according to the actual light output effect requirements (e.g., desired light intensity) and injection molding requirements, and the value of α1 can be specifically determined according to the actual internal space setting of the lamp, injection molding requirements, and aesthetic requirements. After D1, D2, and α1 are determined, the value of α2 and the dimension of the first reflective wall 13a can be calculated using trigonometric functions.

[0105] In some embodiments, in the projection plane perpendicular to the first direction, the dimension of the first reflective wall 13a along the height direction is D1, where D1 is greater than or equal to 7 mm and less than or equal to 10 mm. For example, it can be 7 mm, 7.5 mm, 8 mm, 8.5 mm, 9 mm, 9.5 mm, 10 mm, etc. This range of values ​​helps to meet the size requirements of the first light-emitting area 12a and also reduces the difficulty of injection molding.

[0106] In some embodiments, along the first direction, the distance between the end of the first reflective wall 13a away from the light-emitting wall 12 and the light-emitting wall 12 is D2, where D2 is greater than or equal to 7 mm, such as 7 mm, 7.5 mm, 8 mm, 8.5 mm, 9 mm, 9.5 mm, 10 mm, etc. This range of values ​​helps to meet the actual light output effect requirements (e.g., light intensity).

[0107] In some embodiments, in a projection plane perpendicular to the first direction, the dimension of the first reflective wall 13a along the height direction is D1, and the dimension of the second reflective wall 13b along the height direction is D3, where the ratio of D3 to D1 is greater than or equal to 2.5 and less than or equal to 5. This ratio helps to obtain a better visual effect. Taking D1 as 7mm as an example, D3 can be 17.5mm, 18mm, 18.5mm, 19mm, 20mm, 21mm, 22mm, 23mm, 24mm, 25mm, 26mm, etc.

[0108] 27mm, 28mm, 29mm, 30mm, 31mm, 32mm, 33mm, 34mm, 35mm, etc. This proportion helps to achieve a better visual effect.

[0109] Embodiments of this application also provide a vehicle lighting assembly, see reference to Figures 3-6 The vehicle headlight assembly includes a mounting structure 3, a light guide structure 1, and a light source 2. The mounting structure 3 forms a first mounting cavity 3a. The light guide structure 1 is disposed in the first mounting cavity 3a. The light guide structure 1 includes an incident light wall 11, an exit light wall 12, and at least two reflective walls 13 connected to each other. Light incident from the incident light wall 11 is reflected by the at least two reflective walls 13 to different areas of the exit light wall 12, so as to form at least two exit light areas in the exit light wall 12. The average light intensity of the at least two exit light areas is different. The light source 2 is disposed opposite to the incident light wall 11.

[0110] In this embodiment, the light guide structure 1 can be the light guide structure 1 described in any of the above embodiments. The relevant technical details of the light guide structure 1 mentioned here and below can be referred to the relevant parts of the light guide structure 1 described above, and will not be repeated here.

[0111] The specific structural form of the mounting structure 3 is not limited, as long as it can form the first mounting cavity 3a for mounting the optical guide structure 1.

[0112] In some embodiments, the light entrance wall 11 and the light exit wall 12 are distributed along a first direction and staggered from each other in the height direction. The first direction and the height direction are perpendicular. The light splitting wall 14 and at least two reflective walls 13 are disposed between the light entrance wall 11 and the light exit wall 12. The light splitting wall 14 is disposed opposite to the light entrance wall 11 along the first direction, and the at least two reflective walls 13 are disposed opposite to the light exit wall 12 along the first direction.

[0113] In some embodiments, refer to Figure 3 The mounting structure 3 includes a first support member 31 and a second support member 32, which together form a first mounting cavity 3a. The formation of the first mounting cavity 3a by the first support member 31 and the second support member 32 helps to increase the contact area between the mounting structure 3 and the optical guide structure 1, thereby improving the installation stability of the optical guide structure 1.

[0114] In this embodiment, the first support member 31 and the second support member 32 may or may not be connected to each other, and there is no limitation thereto. As an example, the first support member 31 and the second support member 32 are spaced apart along the height direction. One end of the first support member 31 and the second support member 32 along the first direction forms a light inlet 3b corresponding to the light inlet wall 11, and the other end forms a light outlet 3c corresponding to the light outlet wall 12.

[0115] In some embodiments, refer to Figure 4 The mounting structure 3 includes a first decorative panel 33, which is disposed on one side of the light-emitting wall 12 along the height direction. In the projection plane perpendicular to the first direction, the projection of the first decorative panel 33 covers the projection of the light-emitting wall 11 and the light source 2.

[0116] In this embodiment, due to the obstruction of the first decorative panel 33, the user will not be able to observe the light-receiving wall 11 and the light source 2 inside the headlight from the outside of the headlight, as well as the surrounding structure, thus improving the aesthetics of the headlight.

[0117] The structure of the first decorative panel 33 is not limited, as long as it can achieve the above-mentioned blocking function. The surface of the first decorative panel 33 facing away from the light-incident wall 11 and the light source 2 can be formed with decorative patterns, decorative coatings, etc., without any restrictions.

[0118] In some embodiments, the first decorative panel 33 may further cover at least a portion of the projection of the first support 31 and / or the second support 32.

[0119] In some embodiments, refer to Figure 5 A mounting groove 33a is formed on the side of the first decorative panel 33 facing the first support member 31, and a portion of the structure of the first support member 31 is located within the mounting groove 33a. This further enhances the positional stability of the first support member 31, thereby improving the installation positional stability of the light guide structure 1.

[0120] In other embodiments, reference is made to Figure 3 and Figure 4The first decorative panel 33 and the first support member 31 are formed as an integral injection molding structure. The surface of the first decorative panel 33 facing away from the first support member 31 is recessed to form a decorative groove 33b. The first support member 31 has a connecting end for connecting with the first decorative panel 33. In the projection plane perpendicular to the first direction, the projection of the decorative groove 33b covers the projection of the connecting end.

[0121] In this embodiment, the first decorative panel 33 and the first support member 31 are formed as an integral injection-molded structure, which simplifies the assembly process. Furthermore, it can be understood that during the injection molding process, injection shrinkage marks may form on the first decorative panel 33 at the position corresponding to the connection end with the first support member 31. In this embodiment, a decorative groove 33b is formed at this position on the first decorative panel, which can better conceal the injection shrinkage marks and improve the aesthetics.

[0122] The specific structural form of the decorative groove 33b is not limited. As an example, the decorative groove 33b extends along the second direction, which is perpendicular to the first direction and the height direction respectively (that is, the second direction is the direction perpendicular to the paper in the figure). In the projection plane perpendicular to the second direction, the decorative groove 33b forms a V-shaped structure.

[0123] In some embodiments, the light guide structure 1 includes a first straight wall 15 and a second straight wall 16 disposed on the bottom side of the first straight wall 15. Both the first straight wall 15 and the second straight wall 16 extend along a first direction. The two ends of the light-incident wall 11 along the height direction are respectively connected to the first straight wall 15 and the second straight wall 16. The top end of the beam-splitting wall 14 is connected to one end of the first straight wall 15, and the bottom end is connected to the top end of the light-exiting wall 12. One end of at least one reflective wall 13 is connected to one end of the second straight wall 16, and one end of at least one reflective wall 13 is connected to the bottom end of the light-exiting wall 12. A first support member 31 is connected to the first straight wall 15, and a second support member 32 is connected to the second straight wall 16.

[0124] In this embodiment, the first support member 31 can be connected to the first straight wall 15, and the second support member 32 can be connected to the second straight wall 16. In this embodiment, the connection method between the first support member 31 and the first straight wall 15, and the connection method between the second support member 32 and the second straight wall 16 are not limited, such as snap-fitting, bonding, welding, etc.

[0125] In some embodiments, the first support member 31 includes a first support segment 31a and a first inclined segment 31b. The first support segment 31a extends along a first direction, and the first inclined segment 31b is connected to the first support segment 31a. The first inclined segment 31b extends inclinedly toward the bottom side in a direction away from the first support segment 31a. The first support segment 31a is connected to the first straight wall 15, and the first inclined segment 31b is disposed opposite to the beam splitting wall 14.

[0126] In this embodiment, a first support segment 31a and a first inclined segment 31b are provided on the first support member 31, which correspond to the first straight wall 15 and the beam splitting wall 14 of the light guide structure 1, respectively. This helps to improve the stability of the connection between the first support member 31 and the light guide structure 1.

[0127] In this embodiment, in the projection plane perpendicular to the first direction, the projection of the first decorative panel 33 can cover the projections of the first support segment 31a and the first inclined segment 31b, thus further enhancing the aesthetic appeal.

[0128] In some embodiments, at least two welding positions are formed on the bottom surface of the first support segment 31a, and the at least two welding positions are distributed along a first direction. The welding positions are welded to the first straight wall 15. In this embodiment, the first support segment 31a is connected to the first straight wall 15 by welding, which can improve the connection strength and help reduce the gap between the first support segment 31a and the first straight wall 15, thereby improving the compactness of the structure.

[0129] In some embodiments, the surface of the first inclined segment 31b facing the beam splitter 14 is formed as a reflective surface. As mentioned above, this will enable the light refracted to the outside by the beam splitter 14 to be reflected back into the optical guide interface, thereby improving light utilization.

[0130] In some embodiments, refer to Figure 4 The top surface of the first support member 31 forms at least two connecting structures for fixing to the external structure, and the at least two connecting structures are distributed along the first direction.

[0131] As an example, the connecting structure is used to fix it to the housing of the vehicle lamp. In this embodiment, at least two connecting structures are provided distributed along the first direction, which helps to improve the connection stability between the first support 31 and the external structure, thereby improving the positional stability of the light guide structure 1.

[0132] In this embodiment, the structural forms of at least two connection structures can be the same or different, and there is no limitation on this.

[0133] In some embodiments, at least one connecting structure includes a connecting arm 311, which, together with a first support segment 31a, forms a plug-in cavity, which is open on one side along a first direction. In actual use, an external structure can be inserted into the plug-in cavity, thereby fixing the connecting structure to the external structure. As an example, a vehicle lamp assembly includes a housing 4, the inner surface of which forms a plug-in wall that inserts into the plug-in cavity.

[0134] It should be noted that each connection structure may include the connecting arm 311, or only some of the connection structures may include the connecting arm 311, while the other part of the connection structure adopts other structural forms (such as threaded fasteners, snap-fit ​​fasteners, etc.).

[0135] In some embodiments, specifically, the connecting arm 311 includes a first sub-arm 3111 and a second sub-arm 3112. The first sub-arm 3111 is connected to the first support section 31a and extends in the height direction, and the second sub-arm 3112 is connected to the top of the first sub-arm 3111 and extends in the first direction.

[0136] This type of connecting arm 311 has good structural strength and can be relatively tightly integrated with the external structure, thereby further improving the connection stability between the first support member 31 and the external structure. As an example, in this embodiment, both the first sub-arm 3111 and the second sub-arm 3112 are straight arms.

[0137] In some embodiments, at least two reflective walls 13 include a first reflective wall 13a and a second reflective wall 13b connected to each other. One end of the first reflective wall 13a is connected to the light-emitting wall 12, and one end of the second reflective wall 13b is connected to the second straight wall 16. The second support member 32 includes a second support section 32a and a second inclined section 32b. The second support section 32a extends along a first direction, and the second inclined section 32b is connected to the second support section 32a. Along a direction away from the second support section 32a, the second inclined section 32b extends inclined away from the bottom side. The second support section 32a is connected to the second straight wall 16, and the second inclined section 32b is disposed opposite to the second reflective wall 13b.

[0138] In this embodiment, a second support section 32a and a second inclined section 32b are provided on the second support member 32, which correspond to the second straight wall 16 and the second reflective wall 13b of the light guide structure 1, respectively. In this way, the positional stability of the light guide structure 1 can be further improved.

[0139] Furthermore, it can be understood that the second reflector wall 13b and the light-emitting wall 12 are arranged opposite to each other, that is, the second inclined section 32b and the light-emitting wall 12 are arranged opposite to each other. Therefore, the second inclined section 32b can also serve to shield other structures behind (such as the rear wall of the headlight housing 4) and improve the aesthetics.

[0140] In some embodiments, the surface of the second inclined segment 32b facing the second reflective wall 13b is formed as a reflective surface, as mentioned above. This helps to reflect the light refracted by the second reflective wall 13b back into the light guide structure 1, reducing light loss and improving light utilization.

[0141] In some embodiments, a gap is formed between the second inclined segment 32b and the second reflective wall 13b. As described above, the second inclined segment 32b is disposed opposite to the light-emitting wall 12, that is, it can be observed from outside the vehicle headlight. In this embodiment, a gap is formed between the second inclined segment 32b and the second reflective wall 13b, so that when viewed from outside the vehicle headlight, the light guide structure 1 will appear to be suspended on the second inclined segment 32b, improving the aesthetics.

[0142] In this embodiment, as an example, the distance between the second reflective wall 13b and the second inclined segment 32b along the first direction is greater than or equal to 5mm, such as 5mm, 8mm, 10mm, 12mm, 15mm, 18mm, 20mm, etc.

[0143] In some embodiments, the second support member 32 further includes a third inclined segment 32c connected to the side of the second inclined segment 32b away from the second support segment 32a. The third inclined segment 32c extends inclinedly toward the bottom side in a direction away from the second support segment 32a. The inclination angle of the second inclined segment 32b is greater than that of the third inclined segment 32c. The third inclined segment 32c is spaced apart from and opposite to the first reflective wall 13a.

[0144] In this embodiment, the setting of the third tilting segment 32c can further improve the positional stability of the light guide structure 1, and it can play a similar blocking effect as the second tilting segment 32b, thus improving the aesthetics.

[0145] In some embodiments, the surface of the third inclined segment 32c facing the first reflective wall 13a is formed as a reflective surface. As mentioned above, this helps to reflect the light refracted by the first reflective wall 13a back into the light guide structure 1, reducing light loss and improving light utilization.

[0146] In some embodiments, the third inclined segment 32c extends beyond the light-emitting wall 12 along the first direction. It is understood that the light guide structure 1 may not be the only light-emitting structure in the headlight assembly, and there may be other light-emitting structures on its bottom side. In this embodiment, the third inclined segment 32c extends beyond the light-emitting wall 12 in the first direction, so as to block other light-emitting structures in the headlight assembly, reduce the possibility of interference between them and the light emitted by the light guide structure 1, and improve the light emission effect.

[0147] In some embodiments, the second support member 32 specifically includes a bracket 321 and a second decorative plate 322, with the second decorative plate 322 disposed between the bracket 321 and the light guide structure 1. As mentioned above, the surfaces of the second inclined section 32b, the third inclined section 32c, etc., of the second support member 32 facing the light-emitting wall 12 have a decorative effect and may also have a reflective effect. At the same time, the second support member 32 needs to meet support requirements. Therefore, in this embodiment, the second support member 32 is configured to include a second decorative plate 322 and a bracket 321. The second decorative plate 322 mainly meets the decorative and possible reflective requirements, while the bracket 321 mainly meets the support strength requirements. Compared with an integrated structure, this structural form can reduce the manufacturing difficulty and cost, and helps to better meet the support requirements.

[0148] In this embodiment, the bracket 321 can form a first wall, a second wall, and a third wall corresponding to the second support segment 32a, the second inclined segment 32b, and the third inclined segment 32c, while the second decorative panel 322 can form a first plate surface, a second plate surface, and a third plate surface corresponding to the second support segment 32a, the second inclined segment 32b, and the third inclined segment 32c.

[0149] In some embodiments, refer to Figure 3 and Figure 6 The mounting structure 3 also forms a second mounting cavity 3d, which is formed on the bottom side of the first mounting cavity 3a. The vehicle lamp assembly also includes a signal lamp assembly 5, which is disposed in the second mounting cavity 3d.

[0150] The specific structural form of the second mounting cavity 3d and the signal light assembly 5 is not limited.

[0151] In some embodiments, specifically, the mounting structure 3 includes a third support member 34, which, together with the second support member 32, forms a second mounting cavity 3d. The specific structural form of the third support member 34 is not limited, as long as it meets the installation requirements of the signal light assembly 5.

[0152] In some embodiments, the mounting structure 3 includes a fourth support member 35, which abuts against the side wall of the housing 4 away from the light outlet 3c along the first direction. One end of the first support member 31, the second support member 32, and the third support member 34 along the first direction is connected to the fourth support member 35. In this way, the stability of the relative positions of the first support member 31, the second support member 32, and the third support member 34 can be improved.

[0153] Embodiments of this application also provide a vehicle, the vehicle including the light guide structure 1 as described in any of the above embodiments and / or the lamp assembly as described in any of the above embodiments.

[0154] The vehicle of this application embodiment has all the advantages of the light guide structure 1 and the headlight assembly described in any of the above embodiments, which will not be repeated here.
