Description

Technical Field

[0001] This utility model belongs to the technical field of vehicle lighting, and in particular relates to a vehicle lighting fixture and a vehicle. Background Technology

[0002] With the steady development of the automotive industry, vehicle lights, as an indispensable key component of automobiles, undertake the important tasks of illumination, information communication, and improving vehicle visibility, and their design and function are constantly evolving. Modern consumers' expectations for vehicle lights are no longer limited to performance and practicality; they also place higher demands on the aesthetics of vehicle lights.

[0003] In related technologies, the design of vehicle lights integrating daytime running lights and ambient lighting faces certain technical bottlenecks. Because daytime running lights must strictly comply with optical regulations regarding brightness and uniformity, the luminous efficacy of ambient lights is limited, making it difficult to achieve a dazzling lighting effect. This design compromise not only weakens the overall visual appeal of the vehicle lights but also lowers the perceived quality of the product, failing to fully meet consumers' pursuit of high-quality, personalized lighting experiences. Utility Model Content

[0004] In view of this, it is necessary to provide a vehicle lamp and a vehicle for solving the above-mentioned technical problems.

[0005] A vehicle lighting fixture includes a thick-walled component, a daytime running light, and an ambient light, wherein the daytime running light and the ambient light are both housed within the thick-walled component; the daytime running light generated by the daytime running light can be emitted outward through the thick-walled component.

[0006] The thick-walled component has a textured surface, and the ambient light generated by the ambient light can illuminate the textured surface and be emitted outward through the textured surface.

[0007] Understandably, by adopting a dual-light-path design, daytime running lights are allowed to directly penetrate the thick-walled component and emit outwards, while ambient light is diffused through the textured surface. This achieves a balance between optical performance and aesthetics, ensuring that the daytime running lights fully comply with optical regulations while significantly enhancing the luminous efficacy of the ambient lights. This not only greatly improves the overall visual appeal and technological sophistication of the vehicle lights but also satisfies consumers' pursuit of high-quality, personalized lighting experiences.

[0008] In one embodiment, the thick-walled member includes a first thick-walled member and a second thick-walled member, wherein the first thick-walled member is disposed outside the second thick-walled member and connected to the second thick-walled member;

[0009] The sunlight passes sequentially through the second thick-walled member and the first thick-walled member and is emitted outward;

[0010] The textured surface is disposed on the first thick-walled member, and the ambient light shines on the textured surface after passing through the first thick-walled member.

[0011] Understandably, the use of a split first thick-walled component and a second thick-walled component to assemble a complete thick-walled component structure can not only significantly reduce the manufacturing difficulty of individual components and improve production yield, but also facilitate the processing and shaping of optical surfaces to meet the needs of independent light output for daylight and ambient light.

[0012] In one embodiment, the first thick-walled member includes a boss through which the daylight rays can be emitted outward;

[0013] Furthermore, the textured surface is disposed on the bottom surface of the boss located below the vehicle height direction.

[0014] It is understandable that using the same boss of the first thick-walled component to simultaneously achieve the light output of daytime running lights and ambient lights allows the daytime running lights and ambient lights to be transmitted efficiently in a shared channel while maintaining their respective characteristics. This design simplifies the complexity of the first thick-walled component, reduces production costs, and is conducive to the lightweight and integrated development of vehicle lighting.

[0015] In one embodiment, a refractive surface, a first reflective surface, and a scattering surface are formed on the first thick-walled member, and the ambient light illuminates the textured surface after passing through the refractive surface, the first reflective surface, and the scattering surface in sequence.

[0016] The scattering surface is disposed on the stepped surface of the first thick-walled member for connecting the boss.

[0017] Understandably, by utilizing the synergistic optical effects of the refractive surface, the first reflective surface, and the scattering surface built into the first thick-walled component, the ambient light is precisely guided and focused onto the textured surface. This not only ensures that the ambient light emitted by the second light-emitting element is efficiently collected and uniformly diffused, but also significantly enhances the light quality and intensity of the ambient light through multiple optical processes, ultimately presenting a brilliant and delicate visual performance.

[0018] In one embodiment, a patterned surface is formed on the second thick-walled member, the patterned surface being disposed on a connecting surface on the second thick-walled member for connecting the first thick-walled member; and the daylight rays are emitted outward after passing through the patterned surface.

[0019] Understandably, the scattering and refraction of daylight rays by the patterned surface on the second thick-walled component effectively improves the uniformity of daylight ray intensity distribution, eliminating problems of excessively bright or dark spots. This not only ensures that the daylight lamp's light output meets optical regulations but also improves its luminous efficacy, resulting in a softer and more uniform lighting effect, thus satisfying regulatory requirements while maintaining aesthetic appeal.

[0020] In one embodiment, a second reflective surface is also formed on the second thick-walled member, and at least a portion of the daylight rays are reflected by the second reflective surface and then irradiate the patterned surface.

[0021] Understandably, by adopting the optical design of the second reflective surface on the second thick-walled component, and through the precise angle control of the second reflective surface, all daylight rays can be directed to the patterned surface, thus ensuring the efficient utilization of daylight energy and avoiding light loss.

[0022] In one embodiment, the daytime running light includes a first light-emitting element and a first control board, wherein the first light-emitting element is disposed on the first control board and electrically connected to the first control board;

[0023] The ambient light includes a second light-emitting element and a second control board, wherein the second light-emitting element is disposed on the second control board and is electrically connected to the second control board.

[0024] In one embodiment, the first control board and the second control board are connected as an integral structure;

[0025] The second light-emitting element is positioned below the first light-emitting element in the vehicle height direction.

[0026] Understandably, by integrating the first and second control boards, not only can the installation space of the control structure in the vehicle lights be saved and the internal space layout of the vehicle lights be optimized, but the circuit redundancy problem caused by discrete control boards can also be avoided. This design can effectively reduce material costs and production assembly complexity, and can play a role in improving mass production efficiency.

[0027] In one embodiment, the number of the first light-emitting elements is configured to be multiple, and the multiple first light-emitting elements are arranged sequentially at intervals along the width direction of the vehicle;

[0028] And / or, the number of the second light-emitting elements is configured to be multiple, and the multiple second light-emitting elements are arranged sequentially at intervals along the vehicle width direction.

[0029] This application also claims protection for a vehicle including the vehicle lights described above.

[0030] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0031] The vehicle lighting fixture and vehicle for which this application seeks protection employ a dual-light-path design. By allowing daytime running lights to directly penetrate the thick-walled component and emit outwards, while simultaneously allowing ambient light to be refracted and diffused through the textured surface, a balance between optical performance and aesthetic effect can be achieved. This allows the vehicle lighting fixture to significantly enhance the luminous efficacy of the ambient light while ensuring that the daytime running lights fully comply with optical regulations. This not only greatly improves the overall visual appeal and technological sophistication of the vehicle lighting fixture, but also satisfies consumers' pursuit of high-quality and personalized lighting experiences.

Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0040] like Figure 1 , Figure 3 As shown, the vehicle lighting fixture 100 provided in this application includes a thick-walled member 10, a daytime running light 20, and an ambient light 30. Both the daytime running light 20 and the ambient light 30 are housed within the thick-walled member 10. The daytime running light 201 generated by the daytime running light 20 is emitted outward through the light-transmitting thick-walled member 10. A textured surface 40 is provided on the thick-walled member 10, and the ambient light 301 generated by the ambient light 30 can illuminate the textured surface 40 and be emitted outward through it. Here, the textured surface 40 can be composed of fragmented surfaces of varying heights. It should be noted that when the ambient light 301 illuminates the textured surface 40, the fragmented surfaces of the textured surface 40 will project the ambient light 301 at various angles, allowing the human eye to see different fragmented bright surfaces from different angles, thereby achieving a dazzling optical effect.

[0041] The vehicle lighting fixture 100 of this application adopts a dual-light-path design. By allowing the daytime running light 201 to directly penetrate the thick-walled component 10 and emit outwards, while the ambient light 301 is refracted and diffused through the textured surface 40, a balance between optical performance and aesthetic effect can be achieved. This allows the vehicle lighting fixture 100 to significantly enhance the light efficiency of the ambient light 30 while ensuring that the daytime running light 20 fully complies with optical regulations. This not only greatly improves the overall visual appeal and technological sophistication of the vehicle lighting fixture 100, but also meets consumers' pursuit of high-quality and personalized lighting experiences.

[0042] like Figure 1As shown, in one embodiment, the thick-walled component 10 includes a first thick-walled component 11 and a second thick-walled component 12. The first thick-walled component 11 is disposed on the outside of the second thick-walled component 12 and connected to the second thick-walled component 12. Specifically, the connection can be made by conventional methods such as snap-fit, screw-fit, or adhesive. That is to say, this embodiment uses a split first thick-walled component 11 and second thick-walled component 12 to assemble a complete thick-walled component 10 structure. This not only greatly reduces the manufacturing difficulty of individual components and improves the production yield, but also facilitates the processing and forming of optical surfaces to meet the independent light output requirements of the daytime ray 201 and the ambient ray 301.

[0043] like Figure 1 As shown, in this embodiment, the daylight ray 201 passes through the second thick-walled member 12 and the first thick-walled member 11 in sequence and is emitted outward.

[0044] like Figure 1 , Figure 3 As shown, in one embodiment, the first thick-walled member 11 includes a boss 110 through which the daytime running light 201 can be emitted outward; and a textured surface 40 is disposed on the lower bottom surface 111 of the boss 110 at a position below the vehicle height direction Z. That is to say, the same boss 110 of the first thick-walled member 11 in this embodiment simultaneously realizes the light output of the daytime running light 20 and the ambient light 30, so that the daytime running light 201 and the ambient light 301 are efficiently transmitted in a common channel while maintaining their respective characteristics. This design simplifies the complexity of the first thick-walled member 11, reduces production costs, and is conducive to the lightweight and integrated development of the vehicle lighting fixture 100.

[0045] like Figure 1 , Figure 3As shown, in one embodiment, a refractive surface 101, a first reflective surface 102, and a scattering surface 103 are formed on the first thick-walled member 11. Ambient light 301 illuminates the textured surface 40 after passing through the refractive surface 101, the first reflective surface 102, and the scattering surface 103 in sequence. The scattering surface 103 is disposed on the stepped surface 112 of the first thick-walled member 11 for connecting the boss 110. In other words, this embodiment utilizes the synergistic optical effect of the refractive surface 101, the first reflective surface 102, and the scattering surface 103 built into the first thick-walled member 11 to precisely guide the transmission of ambient light 301 and focus it onto the textured surface 40. This not only ensures that the ambient light 301 emitted by the second light-emitting element 31 is efficiently collected and uniformly diffused, but also significantly improves the light quality and light intensity of the ambient light 301 through multiple optical processing, ultimately presenting a brilliant and delicate visual performance. It should be noted that when the ambient light 301 is transmitted within the first thick-walled member 11, the ambient light 301 can only be emitted outward from the scattering surface 103 under the reflection of the first reflecting surface 102, thereby preventing the ambient light 301 from leaking. Therefore, the first reflecting surface 102 can be specifically distributed on the part of the first thick-walled member 11 corresponding to the transmission of the ambient light 301.

[0046] Here, the refractive surface 101, the first reflective surface 102, and the scattering surface 103 on the first thick-walled component 11 can be formed by existing processing methods on the first thick-walled component 11, which will not be elaborated here.

[0047] like Figure 1 As shown, in one embodiment, a patterned surface 104 is formed on the second thick-walled member 12. The patterned surface 104 is disposed on the connecting surface of the second thick-walled member 12 for connecting the first thick-walled member 11. Furthermore, the daytime running light 201 is emitted after passing through the patterned surface 104. During this process, the patterned surface 104 on the second thick-walled member 12 can scatter and refract the daytime running light 201, thereby improving the uniformity of the light intensity distribution of the daytime running light 201 and eliminating the problem of excessive or dark light spots in certain areas. This not only ensures that the light output of the daytime running light 20 meets optical regulatory requirements but also improves the luminous efficacy quality of the daytime running light 20, making the lighting effect of the daytime running light 20 softer and more uniform, thus meeting regulatory requirements while also considering aesthetics.

[0048] like Figure 1As shown, in this embodiment, a second reflective surface 105 is also formed on the second thick-walled member 12. At least a portion of the daylight rays 201 are reflected by the second reflective surface 105 and then irradiate the patterned surface 104. This ensures that all the daylight rays 201 are guided to the patterned surface 104, thereby ensuring efficient utilization of the light energy of the daylight rays 201 and avoiding light loss. It should be noted that when the daylight rays 201 are transmitted within the second thick-walled member 12, they can only irradiate the patterned surface 104 under the reflection of the second reflective surface 105. This prevents light leakage of the daylight rays 201. Therefore, the second reflective surface 105 can be distributed on the portion of the second thick-walled member 12 corresponding to the transmission area of ​​the daylight rays 201.

[0049] Here, the patterned surface 104 and the second reflective surface 105 on the second thick-walled component 12 can be formed by existing processing methods on the second thick-walled component 12, which will not be elaborated here.

[0050] like Figure 1 As shown, in one embodiment, the daytime running light 20 includes a first light-emitting element 21 and a first control board 22. The first light-emitting element 21 is disposed on the first control board 22 and electrically connected to the first control board 22, so that the vehicle lighting fixture 100 can use the first control board 22 to control the light-emitting operation of the daytime running light 20.

[0051] like Figure 2 As shown, the number of first light-emitting elements 21 is configured to be multiple, and the multiple first light-emitting elements 21 are arranged sequentially at intervals along the vehicle width direction Y. Specifically, the first light-emitting elements 21 can be configured as LED particles. It should be noted that the specific number of first light-emitting elements 21 can be set according to the specific needs of use, which will not be elaborated here.

[0052] like Figure 1 As shown, in one embodiment, the ambient light 30 includes a second light-emitting element 31 and a second control board 32. The second light-emitting element 31 is disposed on the second control board 32 and electrically connected to the second control board 32. This allows the vehicle lighting fixture 100 to control the light-emitting operation of the second light-emitting element 31 using the second control board 32.

[0053] Similarly, the number of second light-emitting elements 31 is configured to be multiple, and the multiple second light-emitting elements 31 are arranged sequentially at intervals along the vehicle width direction Y. Specifically, the second light-emitting elements 31 can be configured as LED particles. It should be noted that the specific number of second light-emitting elements 31 can be set according to the specific needs of use, which will not be elaborated here.

[0054] like Figure 1As shown, in one embodiment, the first control board 22 and the second control board 32 are connected as a single unit, achieving an integrated design. This not only saves installation space for the control structure in the vehicle lighting fixture 100 and optimizes the internal space layout of the vehicle lighting fixture 100, but also avoids the circuit redundancy problems caused by discrete control boards. This design effectively reduces material costs and production assembly complexity, thus improving mass production efficiency. It should be noted that the integration of the first control board 22 and the second control board 32 can be achieved using existing conventional methods, which will not be elaborated upon here.

[0055] like Figure 1 As shown, the second light-emitting element 31 is disposed below the first light-emitting element 21 in the vehicle height direction Z. That is, the control board structure of this embodiment is configured as a double-sided control board.

[0056] In addition, this application also provides a vehicle including the vehicle lighting fixture 100 described above.

[0057] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0058] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Any appropriate changes and variations made to the above embodiments within the scope of the essential spirit of the present utility model shall fall within the scope of protection claimed by the present utility model.
