Description

Technical Field

[0001] This application relates to the field of vehicles, and in particular to a lighting assembly for a vehicle and a vehicle. Background Technology

[0002] In related technologies, the vehicle lighting assembly adopts a split design, with different lighting units independently set in the front area of ​​the vehicle body. This results in the lighting assembly occupying too much space, which conflicts with the space configuration requirements of core components such as the battery compartment and drive module of new energy vehicles. Although there are integrated improvement solutions in the existing technology, most designs still rely on multi-layer stacking or split splicing structures. This not only increases the vertical volume of the lighting module, but also lacks a coordinated design between the mounting brackets of optical elements and functional modules. The redundant structure further aggravates the space occupation problem. Currently, there is a space competition between the vehicle lighting system and autonomous driving perception equipment and aerodynamic kits. Therefore, how to improve the space utilization rate of the vehicle lighting assembly has become the technical problem to be solved in this application. Utility Model Content

[0005] According to the embodiments of this application, the vehicle lamp assembly has a bent space formed inside the lamp cover by the angle between the peripheral wall and the light-emitting wall being greater than zero degrees. This allows internal optical components such as the light guide plate to be designed to fit the bent space, reducing space waste. The bent light guide plate extends to fit the peripheral wall and the light-emitting wall, adapting to the bent space and reducing internal gaps. Furthermore, the light-emitting element is placed on a portion of the edge of the light guide plate, avoiding the extra space occupied by the light-emitting element facing the light guide plate directly. This reduces redundant structures and effectively improves the space utilization of the vehicle lamp assembly.

[0006] According to some embodiments of this application, a vehicle lighting assembly includes a light guide plate comprising: a first light guide portion adjacent to the peripheral wall, wherein a light-inlet end face is formed on one side edge of the first light guide portion and the light-inlet end face is directly opposite the light-emitting element; and a second light guide portion connected to the other side edge of the first light guide portion and inclined relative to the first light guide portion, wherein the second light guide portion is disposed adjacent to the light-emitting wall.

[0007] According to some embodiments of the present application, in a vehicle lighting assembly, at least a portion of the first light guide gradually decreases in thickness in the direction from the light-inlet end toward the second light guide.

Since the vehicle according to this embodiment is equipped with the headlight assembly of any of the above embodiments, the vehicle according to this application has a headlight assembly with higher space utilization, which reduces the size of the headlight assembly itself and provides more lateral space for the battery compartment at the front of the vehicle. This allows for a more compact and reasonable arrangement of the battery pack, increasing battery capacity without adding extra vehicle space.

[0032] The embodiments of this application 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 application, and should not be construed as limiting this application.

[0033] The following is for reference. Figures 1-3 A vehicle lighting assembly 100 for a vehicle is described according to an embodiment of this application.

[0034] According to an embodiment of this application, a vehicle lighting assembly 100 includes a housing 1, a lampshade 2, and a light guide plate 3. The housing 1 has an opening 11, and a receiving space 12 is formed inside the housing 1. The lampshade 2 covers at least a portion of the opening 11. A peripheral wall 21 is formed on the lampshade 2 and is in contact with the housing 1. The lampshade 2 also has a light-emitting wall 22 that is in contact with the peripheral wall 21 and is directly opposite at least a portion of the opening 11. The angle between the peripheral wall 21 and the light-emitting wall 22 is α, and α > 0°. The light guide plate 3 is housed in the receiving space 12. At least a portion of the light guide plate 3 is bent to extend and fit against the peripheral wall 21 and the light-emitting wall 22, respectively. A light-emitting element 4 is provided on a portion of the edge of the light guide plate 3.

[0035] In related technologies, the vehicle lighting assembly 100 adopts a split design, with different lighting units independently set in the front area of ​​the vehicle body. This results in the lighting assembly occupying too much space, which conflicts with the space configuration requirements of core components such as the battery compartment and drive module of new energy vehicles. Although there are integrated improvement solutions in existing technologies, most designs still rely on multi-layer stacking or split splicing structures. This not only increases the vertical volume of the lighting module, but also lacks a coordinated design between the mounting bracket 5 of the optical elements and the functional modules. The redundant structure further aggravates the space occupation problem. Currently, there is a space competition problem between the vehicle lighting system and autonomous driving perception equipment and aerodynamic kits.

[0036] The opening 11 of the housing 1 provides a basic space for the installation of subsequent components. The peripheral wall 21 of the lamp cover 2 is connected to the housing 1, and the light-emitting wall 22 is connected to the peripheral wall 21 at an angle of α > 0°. The angle structure formed by the peripheral wall 21 and the light-emitting wall 22 of the lamp cover 2 creates a bent space inside the lamp cover 2. The light guide plate 3 is at least partially bent and extends to fit the peripheral wall 21 and the light-emitting wall 22 respectively, adapting to the bent space. This avoids the regular shape of the internal space of traditional car lights, which makes it difficult for the light guide plate 3 to make full use of every corner and has the problem of idle space. The light guide plate 3 can fill the space enclosed by the peripheral wall 21 and the light-emitting wall 22, reducing the size of the internal gap. It is understandable that on the side of the lamp cover 2 close to the vehicle body, the angle area formed by the peripheral wall 21 and the light-emitting wall 22 is relatively narrow. The bent light guide plate 3 can be embedded in this area to make full use of the space. This not only improves space utilization, but also allows light to be emitted more effectively through the light-emitting wall 22 when it propagates within the light guide plate 3, thus enhancing the lighting effect.

[0037] Meanwhile, by placing the light-emitting element 4 on a portion of the edge of the light guide plate 3, the need for separate installation space for the light-emitting element, as required in traditional vehicle headlight designs, is avoided, further improving space utilization. By integrating the light-emitting element 4 with the edge of the light guide plate 3, it is unnecessary to create separate space for installing the light-emitting element in other locations. The light guide plate 3 acts as a carrier for light propagation; with the light-emitting element 4 positioned on its edge, the light generated by the light-emitting element 4 can directly enter the light guide plate 3 and quickly propagate within it, then be evenly emitted through the light-emitting wall 22. By placing the light-emitting unit 42 on a portion of the edge of the light guide plate 3, the structure is simplified, space occupancy is reduced, and the overall layout of the vehicle headlight assembly 100 becomes more compact and rational. Furthermore, because the light-emitting element 4 is close to the edge of the light guide plate 3, maintenance and replacement of the light-emitting element 4 are more convenient, requiring less disassembly of other components, saving maintenance time and space.

[0038] According to some embodiments of this application, a vehicle headlight assembly 100 includes a light guide plate 3 comprising a first light guide portion 31 and a second light guide portion 32. The first light guide portion 31 is adjacent to a peripheral wall 21, and a light-inlet end face is formed on one side edge of the first light guide portion 31, which is directly opposite to the light-emitting element 4. The second light guide portion 32 is connected to the other side edge of the first light guide portion 31 and is inclined relative to the first light guide portion 31. The second light guide portion 32 is disposed adjacent to a light-emitting wall 22.

[0039] It should be noted that a light-inlet end face is formed on one side edge of the first light guide 31, which is directly opposite to the light-emitting element 4. When the light-emitting element 4 emits light towards the light-inlet end face, the light enters the first light guide 31. The light can be reflected or refracted inside the first light guide 31 and then enter the second light guide 32, ultimately achieving the emission of light. Because the light-emitting element 4 is only set on one side edge, the traditional bidirectional light-inlet scheme avoids the need to reserve space on the other side to place the light source and related components. The internal space requirement of the lamp is greatly reduced, improving the space utilization rate of the lamp assembly 100 inside the lamp, and providing the possibility for the compact and diversified design of the lamp. At the same time, due to the reduction of the light-emitting element 4, the requirements for the heat dissipation structure, driving circuit and secondary optical elements of the light-emitting element 4 are also reduced accordingly, further optimizing the space utilization. By setting a single-sided light-emitting unit 42, the number of components in the lamp assembly 100 is reduced. While achieving the light emission effect, the space occupation is reduced, and the space utilization rate of the lamp assembly 100 is improved.

[0040] The first light guide 31 is adjacent to the peripheral wall 21. The light-inlet end face formed by one side edge of the first light guide 31 is directly opposite to the light-emitting element 4, so that the light emitted by the light-emitting element 4 can enter the light guide plate 3 most directly and efficiently. This avoids the problem of insufficient docking between the light-emitting element 4 and the light guide plate 3, which would cause a lot of light loss during transmission. This provides a sufficient energy basis for the subsequent propagation of light in the light guide plate 3, which not only ensures that the headlight has sufficient brightness, but also improves energy utilization efficiency, reduces energy waste caused by light loss, and reduces the vehicle's power consumption. The second light guide 32 is connected to the other side edge of the first light guide 31 and is inclined relative to the first light guide 31. At the same time, it is set adjacent to the light-emitting wall 22. Since there is an angle α between the peripheral wall 21 of the lamp cover 2 and the light-emitting wall 22, a bent space is formed inside. The inclined design of the second light guide 32 can fit the bent space, making full use of the irregular area inside the lamp cover 2, reducing the internal gap, and also improving the space utilization of the headlight assembly 100.

[0041] According to some embodiments of this application, in a vehicle lighting assembly 100, at least a portion of a first light guide 31 gradually decreases in thickness in the direction from the light-inlet end toward the second light guide 32.

[0042] Understandably, when at least a portion of the first light guide 31 gradually decreases in thickness from the light-inlet end towards the second light guide 32, light enters the light-inlet end face from the light-emitting element 4 and propagates within the light guide. The wider light-inlet end face can accommodate more light entering. As the thickness gradually decreases towards the second light guide 32, the light is gradually guided and concentrated during propagation. In a conventional light guide with uniform thickness, light may experience energy dispersion during propagation due to scattering and other reasons. However, by gradually decreasing the thickness from the light-inlet end towards the second light guide 32, the light continuously adjusts its propagation angle during propagation, efficiently converging towards the second light guide 32. This reduces light loss within the light guide and improves the efficiency of light propagation from the first light guide 31 to the second light guide 32, thereby ensuring that the light emitted from the light-exit wall 22 has sufficient intensity, providing brighter illumination for the vehicle.

[0043] According to some embodiments of the present application, in a vehicle headlight assembly 100, a first light guide portion 31 has a first microstructure 311 for reflecting light formed on the surface of the first light guide portion 31 facing away from the peripheral wall 21; and / or, a second light guide portion 32 has a second microstructure 312 for reflecting light formed on the side facing away from the light emitting wall 22.

[0044] The surface of the first light guide 31 facing away from the peripheral wall 21 forms a first microstructure 311 for reflecting light. After the light enters the light-inlet end face from the light-emitting element 4, it propagates in the first light guide 31. Some light may propagate in the direction away from the peripheral wall 21 for various reasons. The first microstructure 311 prevents the light from escaping from the light guide plate 3, causing light loss and reducing the lighting efficiency. The first microstructure 311 can reflect the light back into the light guide plate 3, so that the light continues to propagate in the light guide plate 3 and is eventually guided out of the light wall 22. When the light is incident on the first microstructure 311 at a certain angle, according to the principle of light reflection, the light will be reflected to a direction that is more conducive to propagation to the second light guide 32, reducing the scattering and loss of light during propagation, improving the utilization rate of light, and making the light entering the second light guide 32 more concentrated and sufficient.

[0045] On the side of the second light guide 32 away from the light exiting wall 22, a second microstructure 312 for reflecting light is formed. After the light propagates from the first light guide 31 to the second light guide 32, it continues to propagate within the second light guide 32. Similarly, the second microstructure 312 can reflect these light rays back towards the light exiting wall 22, allowing them to rejoin the effective propagation path. When the light propagates to the edge of the second light guide 32 and its direction is away from the light exiting wall 22, the second microstructure 312 will reflect the light rays back, changing the direction of light propagation and allowing the light rays to propagate towards the light exiting wall 22, and finally exit from the light exiting wall 22.

[0046] When the first microstructure 311 of the first light guide 31 and the second microstructure 312 of the second light guide 32 are present simultaneously, they work together to further improve the performance of the vehicle lamp assembly 100. The first microstructure 311 ensures that light propagates efficiently within the first light guide 31 and is guided to the second light guide 32 as much as possible. The second microstructure 312 ensures that the light entering the second light guide 32 can be emitted from the light exit wall 22 to the maximum extent. The combination of the two greatly reduces the loss of light in the entire light guiding process and significantly improves the utilization rate of light. This allows the vehicle lamp to produce a brighter and more uniform lighting effect under the same light source power, improving the efficiency of the vehicle lighting system and also helping to reduce energy consumption.

[0047] According to some embodiments of the present application, a vehicle lighting assembly 100 has a first microstructure 311, which is a plurality of spaced-apart structures on the surface of a first light guide 31, and each first microstructure 311 is configured as a protrusion or a groove; and a second microstructure 312 is a plurality of spaced-apart structures on the surface of a second light guide 32, and each second microstructure 312 is configured as a protrusion or a groove.

[0048] It is understood that the first microstructure 311 consists of multiple protrusions or grooves spaced apart on the surface of the first light guide 31, and the second microstructure 312 consists of multiple protrusions or grooves similarly spaced apart on the surface of the second light guide 32. When light enters the first light guide 31 and encounters the first microstructure 311, the protrusions or grooves reflect and guide the light to the second light guide 32, preventing light escape and excessive scattering, thus improving transmission efficiency. After the light enters the second light guide 32, the second microstructure 312 reflects back any light that may have strayed from the light-emitting wall 22, ensuring uniform light distribution. The two work together to optimize the entire process from light transmission to light emission, improving light utilization and illumination quality, providing good visual support for vehicle driving, and ensuring safety.

[0049] At the same time, the protrusions or grooves can also prevent local areas of the light-emitting wall 22 from being too bright. The protrusions or grooves can reflect the light to relatively dark areas, making the light more evenly distributed inside the light guide plate 3. If the light in a certain area is strong, when the light encounters the protrusions or grooves near that area, it will be reflected to the area with weaker light, thereby making the light intensity of the entire light-emitting surface 12 more uniform, avoiding the appearance of bright spots or dark areas, improving the uniformity of vehicle headlight illumination, and providing the driver with a clearer and more stable lighting vision.

[0050] According to some embodiments of this application, a vehicle headlight assembly 100 has a first microstructure 311 configured as a stepped pattern arranged sequentially on the surface of a first light guide portion 31; and a second microstructure 312 configured as a stepped pattern arranged sequentially on the surface of the first light guide portion 31.

[0051] Both the first microstructure 311 and the second microstructure 312 are stepped patterns arranged sequentially. After light enters the first light guide 31 from the light-emitting element 4, it encounters the stepped pattern and undergoes continuous reflection and refraction on the vertical and inclined surfaces of the steps. Each step acts as a light control unit, causing the light propagation direction to change at multiple angles, initially dispersing and converging in an orderly manner towards the second light guide 32, thus initially optimizing the light distribution. When the light enters the second light guide 32 and encounters the stepped pattern again, it continues to be reflected and refracted at the steps, further fine-tuning the propagation direction. The light in the originally relatively concentrated area is dispersed to a weaker area, making the light distribution in the second light guide 32 more uniform. From the entry to the exit of the light, the first and second microstructures 312 work together to control the light multiple times. With their cooperation, the light finally achieves a uniform distribution on the light-emitting wall 22, presenting a uniform light emission effect, providing the driver with a clear and bright lighting vision, and improving driving safety.

[0052] According to some embodiments of this application, a vehicle headlight assembly 100 further includes a bracket 5, which is disposed within a receiving space 12 and at least a portion of the bracket 5 is bent to fit against a first light guide portion 31 and a second light guide portion 32, respectively. A limiting portion 51 suitable for cooperating with a light guide plate 3 is formed on the bracket 5.

[0053] The bracket 5 is at least partially bent and respectively attached to the first light guide 31 and the second light guide 32, providing a stable support structure for the light guide plate 3. The bracket 5 is attached to the first light guide 31, which can prevent the first light guide 31 from shifting due to vibration or other reasons during vehicle operation. When the vehicle passes over bumpy roads, the bracket 5 can effectively buffer the impact of vibration on the first light guide 31, ensuring that it is always in the optimal light transmission position. The part of the bracket 5 attached to the second light guide 32 can ensure the stability of the position of the second light guide 32, avoiding its shaking and causing changes in the light transmission path, which would affect the light output effect. At the same time, the limiting part 51 formed on the bracket 5 cooperates with the light guide plate 3, further improving the installation accuracy of the light guide plate 3. The limiting part 51 can more accurately limit the position of the light guide plate 3, so that the light-inlet end face of the first light guide 31 and the light-emitting element 4 are always aligned, ensuring that light can enter the light guide plate 3 efficiently. The second light guide 32 is positioned appropriately relative to the light-emitting wall 22, ensuring that light rays are accurately emitted from the light-emitting wall 22 after propagation through the second light guide 32. In actual production and assembly, the limiting part 51 also provides workers with clear installation references, improving assembly efficiency and quality, and ensuring that each vehicle lamp assembly 100 achieves optimal light transmission performance.

[0054] According to some embodiments of this application, a vehicle headlight assembly 100 includes a light-emitting element 4 comprising a substrate 41, a light-emitting unit 42, and a light-concentrating element 43. The substrate 41 is housed within a receiving space 12, and at least a portion of the substrate 41 is directly opposite the inner edge of a light guide plate 3. The light-emitting unit 42 is disposed on the substrate 41 and emits light toward the light-inlet end face of the first light guide portion 31. The light-concentrating element 43 is disposed between the light-emitting unit 42 and the light-inlet end face and is used to refract the light emitted by the light-emitting unit 42.

[0055] The substrate 41 is at least partially aligned with the inner edge of the light guide plate 3, and the light-emitting unit 42 is disposed on the substrate 41 and emits light towards the light-inlet end face of the first light guide section 31, so that the light emitted by the light-emitting unit 42 can be directly directed to the light-inlet end face, avoiding ineffective scattering of light during transmission and ensuring that the light accurately enters the first light guide section 31. At the same time, the electronic unit disposed on the substrate 41 can precisely control the light-emitting unit 42, such as adjusting the light intensity and frequency.

[0056] The concentrator 43 is positioned between the light-emitting unit 42 and the light-inlet end face. It can refract the light emitted from the light-emitting unit 42. The light emitted from the light-emitting unit 42 is originally divergent. If it directly enters the light-inlet end face, some light will not be able to propagate effectively due to the angle problem. The concentrator 43 concentrates the divergent light through refraction, so that more light enters the light-inlet end face at a suitable angle, thereby improving the light utilization rate and enhancing the lighting efficiency of the vehicle headlight.

[0057] According to some embodiments of this application, a vehicle headlight assembly 100 further includes: a decorative cover 6, which is disposed on the housing 1 and located inside the lamp cover 2, and a refractive plate 61 is formed on the decorative cover 6 facing the light guide plate 3.

[0058] The reflector plate 61 formed on the decorative cover 6, directly opposite the light guide plate 3, illuminates the light emitted from the light guide plate 3. The reflector plate 61 can refract and scatter the light according to design requirements, changing the direction and distribution of light propagation. On one hand, it can make the light diffuse more evenly, avoiding localized over-brightness or under-brightness, thereby improving the uniformity of the headlights. At night, uniform illumination allows the driver to see the entire road more clearly, reducing visual fatigue. On the other hand, the reflector plate 61 can also create unique lighting effects, such as halos and light and shadow changes, adding to the vehicle's appeal and improving its visibility on the road to some extent.

This allows for a more compact and reasonable arrangement of the battery pack, increasing battery capacity without adding extra vehicle space. For the drive module, the saved space can be used to optimize its heat dissipation structure, such as installing larger heat sinks or adding efficient air-cooling pipes, thereby improving the performance and stability of the drive module.
