[0020] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0021] With the diversification of car headlight designs, the demand for headlight illumination is also increasing. Daytime running lights are an indispensable type of light for vehicle operation. However, the current daytime running lights generally do not provide adequate illumination and cannot achieve uniform light output over a large area.

[0022] The following is for reference. Figures 1-3 Description of a vehicle lighting assembly according to an embodiment of the present utility model.

[0023] The vehicle lamp assembly 1 according to this utility model includes: a bracket 11, a light guide strip 12, a light-emitting element 13, and an inner lamp cover 14. The bracket 11 extends in a first direction and forms a positioning part 111 arranged in the first direction. The light guide strip 12 is configured to be a plurality of light guide strips arranged in a second direction, and the plurality of light guide strips 12 respectively cooperate with the positioning part 111. The light-emitting element 13 is disposed at one end of the light guide strip 12 and emits light to the plurality of light guide strips 12 respectively. The inner lamp cover 14 is disposed on the bracket 11 and located on the light-emitting side of the light guide strip 12. The inner lamp cover 14 has a light guide pattern on its wall surface facing the light guide strip 12 that is directly opposite to at least one light guide strip 12.

[0024] The vehicle lamp assembly 1 according to this utility model is provided with a bracket 11, which is the basic support structure of the entire vehicle lamp assembly 1. The bracket 11 extends in a first direction, so that the vehicle lamp assembly 1 can better adapt to the layout of the vehicle interior. A positioning part 111 is formed on the bracket 11 along the first direction, which provides a precise installation position for the light guide strip 12 and ensures the stability of the light guide strip 12.

[0025] The light guide strip 12 is the core component of the vehicle lamp assembly 1. The light guide strip 12 can control and change the propagation path and direction of light. Multiple light guide strips 12 are configured in a second direction, increasing the light-emitting area. Each light guide strip 12 can cooperate with the positioning part 111 on the bracket 11, achieving precise positioning and ensuring the stability of the light guide strip 12 assembly. A light-emitting element 13 is disposed at one end of the light guide strip 12, emitting light into the multiple light guide strips 12, providing sufficient light for the light guide strips 12. The light emitted by the light-emitting element 13 enters the light guide strip 12, is reflected within the light guide strip 12, and finally exits through the light-emitting side of the light guide strip 12. An inner lamp cover 14 is disposed on the bracket 11 and located on the light-emitting side of the light guide strip 12. The light emitted from the light-emitting side of the light guide strip 12 illuminates the outside world after passing through the inner lamp cover 14, thereby illuminating the vehicle lamp assembly 1. The inner lamp cover 14 has a light guide pattern formed on the inner wall facing the light guide strip 12. The light guide pattern is directly opposite the light guide strip 12. The light guide pattern can be understood as the texture set on the headlight lens. The light guide pattern can optimize the light output effect of the headlight assembly 1. When light passes through the light guide pattern, it can cause the light to be scattered and refracted, thereby forming a more uniform and softer light output effect. It effectively avoids the problem of light being too concentrated or dazzling, and improves the light output efficiency and uniformity of the headlight assembly 1, as well as the overall lighting quality and visual effect of the headlight assembly 1.

[0026] In some embodiments, multiple light guide strips 12 are stacked in the second direction, and the wall thickness at the connection between two adjacent light guide strips 12 can be 2.5 mm, which can ensure the structural strength of the parts and improve the light efficiency and brightness of the light guide strips 12.

[0027] According to one embodiment of the present invention, each light guide strip 12 has a reflective area extending in a first direction on the side opposite to the inner lampshade 14, and light guide teeth 121 are formed in the reflective area. When light enters the light guide strip 12, total internal reflection occurs, which reduces light loss during propagation in the light guide strip 12. Therefore, a reflective area can be provided on the side of the light guide strip 12 opposite to the light-emitting side and away from the inner lampshade 14. Light guide teeth 121 are provided in the reflective area. The light guide teeth 121 can disrupt total internal reflection within the light guide strip. Light passing through the reflective area no longer undergoes total internal reflection. The light guide teeth 121 change the light transmission path and direction, causing the light to propagate towards the light-emitting side of the light guide strip 12. Furthermore, due to the effect of the light guide teeth 121, light passing through the light-emitting side of the light guide strip 12 will not undergo total internal reflection but will be directly refracted out of the light guide strip 12 and directed towards the inner lampshade 14. The reflective area and light guide teeth 121 allow light to be smoothly extracted from the reflective area, thereby increasing the light extraction efficiency of the light guide strip 12. In addition, the light guide teeth 121 can also make the light mix evenly before it is emitted from the light guide strip 12, thereby improving the uniformity of the final light emitted by the headlight assembly 1.

[0028] The reflective zone further optimizes the light reflection path, allowing more light to be effectively utilized and directed to the desired light output direction. The light guide teeth 121 increase the number of reflections and angle variations of light within the reflective zone, helping to distribute light more evenly across the entire light-emitting surface. This further enhances the light output uniformity and brightness of the headlight assembly 1, making it suitable for scenarios requiring large-area uniform illumination, such as vehicle daytime running lights, and significantly improving vehicle visibility and driving safety.

[0029] In some embodiments, the shape and size of the light guide teeth 121 can be designed and adjusted according to actual needs to achieve the best light output effect. For example, in some embodiments, the light guide teeth 121 can be constructed as sawtooth, wavy, or other suitable shapes to better control and guide the propagation direction of light.

[0030] According to one embodiment of this utility model, the distance between the reflective area and the light-emitting element 13 is d and satisfies: 70mm≤d≤90mm. Since the light-emitting element 13 is located at the end of the light guide strip 12, the reflective area of ​​the light guide strip 12 needs to be designed to ensure sufficient light output. Specifically, the distance d between the reflective area and the light-emitting element 13 needs to satisfy: 70mm≤d≤90mm, wherein, preferably, d=80mm. A distance of 70mm~90mm between the reflective area and the light-emitting element 13 can ensure that the light is fully reflected and mixed within the light guide strip 12, thereby achieving an ideal light output effect. When d is less than 70mm, the end of the light guide strip 12 will be relatively bright, and the light will not be sufficiently reflected within the light guide strip 12, resulting in uneven light output; while when d is greater than 90mm, the reflective area is too far away from the light-emitting element 13, which will lead to a reduction in the final lateral light output area of ​​the vehicle lamp assembly 1 and a decrease in light output efficiency. Therefore, by controlling the distance between the reflective area and the light-emitting element 13 within the range of 70mm to 90mm, both light emission uniformity and light emission efficiency can be taken into account, thereby improving the overall performance of the vehicle lamp assembly 1.

[0031] According to one embodiment of this utility model, the density of the light guide teeth 121 is gradually increased in the direction away from the light-emitting element 13. The density of the light guide teeth 121 needs to be designed according to the propagation of light within the light guide strip 12. After the light emitted from the light-emitting element 13 enters the light guide strip 12, it gradually attenuates during propagation. By configuring the density of the light guide teeth 121 to gradually increase in the direction away from the light-emitting element 13, sparser light guide teeth 121 can be set in areas with stronger light, allowing most of the light to continue propagating forward; while denser light guide teeth 121 can be set in areas with weaker light, fully disrupting total internal reflection of light, allowing more light to refract out of the light guide strip 12, thereby ensuring the uniformity of light output from the entire light guide strip 12. This effectively improves the uniformity and brightness of light output from the vehicle lamp assembly 1, enabling the vehicle lamp to provide a higher quality and more stable lighting effect when lit, meeting the lighting needs of the vehicle in different driving environments.

[0032] According to one embodiment of the present invention, the positioning part 111 is configured as a receiving groove extending in a first direction, and the receiving groove is configured as a plurality of grooves spaced apart in a second direction, with at least a portion of each light guide strip 12 embedded in the corresponding receiving groove.

[0033] The positioning part 111 adopts a receiving groove design, providing a stable and precise installation position for the light guide strip 12. The receiving groove extends in the first direction, matching the length direction of the light guide strip 12, ensuring that the light guide strip 12 can be smoothly embedded within it. Simultaneously, multiple receiving grooves are spaced apart in the second direction, corresponding to the arrangement of multiple light guide strips 12, ensuring that each light guide strip 12 can find its corresponding installation position. This achieves precise positioning and stable assembly of the light guide strip 12, improving the assembly efficiency of the vehicle lamp assembly 1 and enhancing its overall structural strength, ensuring the stability and reliability of the vehicle lamp assembly 1 during use. The accurate embedding of the light guide strip 12 into the receiving groove and its relative positional relationship with surrounding optical elements (such as the bracket 11, the light-emitting element 13, etc.) are more stable, reducing scattering and loss of light during transmission caused by positional deviation of the light guide strip 12. The light guide strip 12 can more smoothly transmit the light emitted by the light-emitting element 13 to the required position, ensuring the continuity and efficiency of light transmission, thereby improving the luminous effect of the vehicle lamp.

[0034] According to one embodiment of this utility model, multiple light guide strips 12 are connected to end plates 15 on the same side. The end plates 15 have fixing holes 151 formed on them, and are connected to the bracket 11 by fasteners passing through the fixing holes 151. The connection of the multiple light guide strips 12 on the same side via the end plates 15 enhances the structural integrity between the light guide strips 12. The fixing holes 151 on the end plates 15 provide precise positions for the fasteners. By connecting the end plates 15 to the bracket 11 or the vehicle body through the fixing holes 151, the end plates 15 and bracket 11 are fixed together. This not only ensures the stable position of the light guide strips 12 in the vehicle lamp assembly 1, preventing loosening or displacement during use, but also improves the overall structural strength and durability of the vehicle lamp assembly 1. During vehicle operation, the vehicle lamp assembly 1 is subjected to various vibrations and impacts. The stable connection between the end plates 15 and the bracket 11 effectively resists these external forces, ensuring the normal operation and light output effect of the vehicle lamp assembly 1.

[0035] In addition, positioning holes can be provided on the end plate 15. During the assembly of the vehicle light assembly 1, the operator can quickly and accurately fix the light guide strip 12 on the bracket 11 through the positioning holes on the end plate 15, which greatly improves the assembly efficiency.

[0036] According to one embodiment of the present invention, at least a portion of the outer edge of the end of the light guide strip 12 is connected to the end plate 15. In the design, the end plate 15 is an indispensable structure at the end of the light guide strip 12, enabling the fixation of the light guide strip 12. In related technologies, the end structure of the light guide strip 12 typically covers the entire outer periphery of the end face of the light guide strip 12. Since the light-emitting element 13 is located at one end of the light guide strip 12, when the light-emitting element 13 emits light, some light rays entering the end face of the light guide strip 12 are affected by the fully covered end structure and cannot enter the light guide strip 12. However, in the present invention, the end structure of the light guide strip 12 is optimized in the vehicle lamp assembly 1. At least a portion of the outer edge of the end of the light guide strip 12 is connected to the end plate 15, rather than being fully covered. This design ensures the fixation function of the end plate 15 for the light guide strip 12 while reducing the obstruction of light by the end plate 15. Specifically, the end plate 15 only connects to a portion of the outer edge of the end of the light guide strip 12, so that the light emitted by the light-emitting element 13 can enter the light guide strip 12 more smoothly, reducing light loss at the end and improving light utilization.

[0037] According to one embodiment of the present invention, the vehicle headlight assembly 1 further includes a cover plate 16, which is disposed at one end of the light guide strip 12 near the light-emitting element 13 and is adapted to block at least a portion of the light guide strip 12. The cover plate 16, disposed at one end of the light guide strip 12 near the light-emitting element 13 and blocking at least a portion of the light guide strip 12, can effectively block some stray light emitted by the light-emitting element 13. During the operation of the vehicle headlight, the light emitted by the light-emitting element 13 does not all follow the ideal path; some light will scatter in unexpected directions. If these stray lights are emitted directly, they may form undesirable optical phenomena such as halos and glare around the headlight, affecting the lighting effect of the headlight and the driver's vision. The blocking effect of the cover plate 16 can prevent these stray lights from escaping, making the light emitted by the headlight more concentrated and pure, thus improving the lighting quality.

[0038] According to one embodiment of the present invention, the vehicle lamp assembly 1 further includes: an outer cover 17, which is disposed at the end of the cover plate 16 and defines an installation space between the outer cover 17 and the bracket 11, wherein at least a portion of the light-emitting element 13 and / or the end plate 15 is housed within the installation space. The outer cover 17, disposed at the end of the cover plate 16 and together with the bracket 11, forms the installation space. At least a portion of the light-emitting element 13 or the end plate 15 can be located within the installation space. The installation space effectively isolates the light-emitting element 13 or the end plate 15 from the influence of the external environment, ensuring the light emission quality of the vehicle lamp assembly 1 and extending the service life of the vehicle lamp assembly 1.

[0039] In some embodiments, the outer surface of the inner lamp cover 14 may be laser-etched with patterns, which can enhance the aesthetics and personalization of the headlight assembly 1. These patterns can be formed into various unique shapes and textures on the surface of the inner lamp cover 14 through a precise laser process, improving the visual effect of the headlight and adding a touch of fashion and technology to the vehicle. At the same time, the design of the laser pattern can also be customized according to different vehicle models and user needs, meeting diverse market demands.

[0040] In some embodiments, the first direction can be understood as the vehicle width direction, and the second direction can be understood as the vehicle height direction.
