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

[0028] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0029] The following will describe in detail the vehicle lighting components and vehicle of this application with reference to the accompanying drawings and specific embodiments.

[0030] In existing technologies, each functional optical module emits light in a single direction, generally parallel to the front and rear directions of the vehicle. Each module occupies internal space in the headlight, which is not conducive to the personalized and flat design of the headlight.

[0031] To address the aforementioned technical problems, this application provides a vehicle lighting assembly, including a first optical module and a second optical module. The second optical module is disposed on the light-incident side of the first optical module, and the main light-emitting direction of the second optical module forms an acute angle with the main light-emitting direction of the first optical module. In a three-dimensional coordinate system, a projection plane η perpendicular to the X-axis is defined. The orthographic projection of the first optical module onto the projection plane η overlaps with the orthographic projection of the second optical module onto the projection plane η. The X-axis is parallel to the main light-emitting direction of the first optical module. This will be described in detail below.

[0032] See Figure 1-2 The vehicle headlight assembly includes a first optical module 10 and a second optical module 20. The second optical module 20 is disposed on the light-incident side of the first optical module 10, and the main light-emitting direction of the second optical module 20 is set at an acute angle to the main light-emitting direction of the first optical module 10. In a three-dimensional coordinate system, a projection plane η is defined perpendicular to the X-axis direction. The orthographic projection of the first optical module 10 on the projection plane η overlaps with the orthographic projection of the second optical module 20 on the projection plane η. The X-axis direction is parallel to the main light-emitting direction of the first optical module 10.

[0033] For ease of explanation, in the following embodiments, the X-axis direction is the forward and backward direction of the vehicle.

[0034] The second optical module 20 is set on the light-incident side of the first optical module 10, and there is an overlap between the orthographic projections of the two optical modules (the first optical module 10 and the second optical module 20, the same below) on the projection plane η. This allows the second optical module 20 to be arranged using the space on the light-incident side of the first optical module 10, reducing the space occupied by the two optical modules in the vertical direction. While meeting the diverse usage requirements of the vehicle headlight (the two optical modules can be set as corresponding functional modules according to the actual usage situation), it can avoid occupying too much space in the vehicle headlight, which is conducive to the arrangement of other components inside the vehicle headlight and also conducive to the flat and personalized setting of the vehicle headlight.

[0035] In addition, the two optical modules are set at an acute angle to each other, which avoids interference between the light from the two optical modules and helps to improve the overall lighting effect. The acute angle setting also allows the light emitted by the two optical modules to be emitted along the front-to-back direction of the vehicle (when the headlight assembly is used as a front light, it is emitted towards the front of the vehicle; when the headlight assembly is used as a rear light, it is emitted towards the rear of the vehicle), which improves the road illumination effect and visual recognition, and enhances driving safety; at the same time, it can also meet the personalized design requirements of the headlights.

[0036] Specifically, in this embodiment, the main light emission direction of the first optical module 10 is parallel to the X-axis direction, that is, the light emitted by the first optical module 10 is directed towards the front of the vehicle, and the light emitted by the second optical module 20 is directed towards the upper right of the front of the vehicle. Figure 1 The first optical module 10 can be applied to traffic lights, and the second optical module 20 can be applied to autonomous driving warning lights. The second optical module 20 emits light towards the upper right, which helps to improve the visual recognition of pedestrians and other drivers, and improves driving safety.

[0037] Of course, in some embodiments, the main light emission direction of the second optical module 20 can also be tilted to the lower right. In practical applications, the second optical module 20 can be used as supplementary lighting, width indicator, etc. Tilting to the lower right is beneficial for illuminating the area near the vehicle body, improving the visibility of the vehicle at night, and can also improve the road lighting effect near the vehicle body in low light conditions. For example, when driving on mountain roads at night, it is beneficial for improving the driver's observation of road conditions (when driving on mountain roads, the road is curved, and it is necessary to observe the road conditions near the vehicle body), thus improving driving safety. In other embodiments, it can also be a module design with other functions, such as welcome lights, etc., and is not limited to this.

[0038] It is worth mentioning that the first optical module 10 and the second optical module 20 can also be used for the same function at the same time. The two optical modules can widen the illumination range and emit light from two directions at the same time, resulting in high visual recognition and good visual effect.

[0039] In some embodiments, the light emitted by the second optical module 20 can also be tilted toward the left and right sides of the vehicle, which helps to widen the illumination width of the headlights in the horizontal direction, and is not limited to this.

[0040] In some embodiments, the vehicle light assembly further includes a bracket 30, on which the first optical module 10 and the second optical module 20 are respectively disposed.

[0041] Both the first optical module 10 and the second optical module 20 are mounted on the same bracket 30, which helps to improve the accuracy of the relative position between the two optical modules, thereby improving the overall lighting effect; and the two optical modules share a bracket 30, reducing the installation structure and thus reducing the space occupied inside the headlight.

[0042] In practical applications, the existing bracket 30 of the vehicle headlight can be used to install the optical module. For example, the bracket 30 of the existing first optical module 10 can be used to install the second optical module 20. That is, the second optical module 20 is installed on the bracket 30 of the first optical module 10. The second optical module 20 is installed using the original space of the bracket 30 of the first optical module 10, which avoids the second optical module 20 occupying the internal space of the vehicle headlight, reduces the use of parts, and reduces production costs and installation difficulty. At the same time, it can also improve the versatility of vehicle headlight use and avoid the vehicle headlight having a single function.

[0043] In some embodiments, the second optical module 20 includes a second light guide component 21, a flexible circuit board 22, and a mounting bracket 23. The second light guide component 21 is disposed on the bracket 30, and the flexible circuit board 22 is disposed on the light-incident side of the second light guide component 21 through the mounting bracket 23. The light-emitting surface of the second light guide component 21 is coplanar with the surface of the bracket 30. There is an overlap between the orthographic projection of the mounting bracket 23 on the projection surface η and the orthographic projection of the first optical module 10 on the projection surface η.

[0044] The flexible circuit board 22 (with LED beads on its surface) is made of flexible material and can be bent to a certain extent. Compared with the traditional printed circuit board 12, it can better fit the shape, expand the illumination range of the car lights, meet personalized design needs, avoid step-like splicing seams, and improve the continuity and uniformity of the overall illumination. The light-emitting surface of the second light guide component 21 is coplanar with the surface of the bracket 30 (this surface can be one of the two surfaces opposite to the bracket; in some embodiments, the light-emitting surface of the second light guide component 21 can also be set in the middle of the two surfaces). That is, the light-emitting surface of the second light guide component 21 does not protrude from the bracket 30 and does not occupy the space outside the bracket 30, which helps to reduce the space occupied in the vertical direction. In some embodiments, it will not affect the propagation of the light from the high and low beam modules 40. At the same time, there is an overlap between the orthographic projection of the mounting bracket 23 on the projection surface η and the orthographic projection of the first optical module 10 on the projection surface η. The mounting bracket 23 makes full use of the space on the light-incident side of the first optical module 10, reducing the overall space occupied in the vertical direction.

[0045] It is worth mentioning that, compared with the traditional printed circuit board 12, the flexible circuit board 22 occupies less space and can be placed closer to the light-incident side of the second light guide component 21, thus reducing space occupation.

[0046] It should be noted that in actual use, the flexible circuit board 22 can be bonded to the mounting bracket 23 with transparent silicone adhesive, which is simple in structure, convenient and reliable in use; the second light guide component 21 is set on the bracket 30, that is, the bracket 30 has a through hole, and the second light guide component 21 is embedded in the through hole. The original bracket 30 inside the car light can be used to make a hole and then install the second light guide component 21, which reduces the number of parts used, simplifies the installation structure, and at the same time, can also improve the versatility of the car light.

[0047] In some embodiments, the first optical module 10 includes a first light guide component 11 and a printed circuit board 12. The printed circuit board 12 is disposed on the light-incident side of the first light guide component 11 and on the side of the flexible circuit board 22 away from the second light guide component 21. A projection surface λ is set perpendicular to the main light-emitting direction of the second optical module 20, and there is an overlap between the orthographic projection of the printed circuit board 12 on the projection surface λ and the orthographic projection of the flexible circuit board 22 on the projection surface λ.

[0048] The flexible circuit board 22 is placed on top of the printed circuit board 12. When the flexible circuit board 22 and the LEDs on the printed circuit board 12 are lit, the flexible circuit board 22 can block the light emitted by the LEDs on the printed circuit board 12, preventing the light from affecting the light emission of the LEDs on the flexible circuit board 22. At the same time, the printed circuit board 12 is located on the side of the flexible circuit board 22 away from the second light guide component 21, so the light emitted by the LEDs on the flexible circuit board 22 will not affect the light emitted by the LEDs on the printed circuit board 12, thus improving the lighting effect of the two optical modules.

[0049] In some embodiments, the light-emitting surface of the second light guide component 21 is textured.

[0050] The texture can shield the relevant structures on the light-incident side of the second light guide component 21, preventing the internal structure from being seen through the second light guide component 21, which is beneficial to improving the static visual effect of the headlight (second optical module 20); at the same time, the texture can also homogenize the light emitted from the second light guide component 21, improve the lighting effect, and have a good visual effect.

[0051] In some embodiments, the bracket 30 has a first mounting portion 31 and a second mounting portion 32 connected together. A first light guide component 11 is disposed on the first mounting portion 31, and a second light guide component 21 is disposed on the second mounting portion 32. The first mounting portion 31 and the second mounting portion 32 are set at an angle θ, satisfying: 90°≤θ≤120°, such as 90°, 100°, 110°, 120°, etc.

[0052] The angle between the first mounting portion 31 and the second mounting portion 32 reflects the relative position between the second optical module 20 (i.e., the second light guide component 21) and the first optical module 10 (i.e., the first light guide component 11).

[0053] Specifically, when θ is less than 90°, the distance between the first light guide component 11 and the second light guide component 21 is too close, and the angle space formed by the first mounting part 31 and the second mounting part 32 (the light-incident side of the first light guide component 11) is too small, which is not conducive to the arrangement and installation of the second optical module 20. Furthermore, when θ is too small, the angle between the main light-emitting directions of the first light guide component 11 and the second light guide component 21 is too large, and the light easily shines into non-illuminated areas (e.g., ...). Figure 1 In the field of view, the X-axis direction remains unchanged. As the angle between the two main light-emitting directions increases, the direction U is towards the left side of the headlight. The light emitted by the second light guide component 21 is emitted to the left (which is an ineffective light), resulting in a poor overall lighting effect.

[0054] When θ is greater than 120°, the main light output directions of the first light guide component 11 and the second light guide component 21 tend to be parallel. That is, the vertical distance between the side of the second light guide component 21 away from the first light guide component 11 and the first light guide component 11 increases, meaning that the second light guide component 21 occupies more vertical space.

[0055] In some embodiments, the angle between the main light-emitting direction of the first optical module 10 and the main light-emitting direction of the second optical module 20 is β, which satisfies: 65°≤β≤85°, and satisfies: 65°, 75°, 85°, etc.

[0056] When the value of β is less than 65°, the angle between the main light-emitting directions of the two optical modules is small, and light interference is likely to occur between the two optical modules, which is not conducive to improving the overall lighting effect. In addition, the smaller the angle between the main light-emitting directions of the two optical modules, the more volume is occupied in the vertical direction, which is not conducive to the overall flat design. When the value of β is greater than 85°, the main light-emitting direction of the second optical module 20 tends to be emitted in the vertical direction, which is not conducive to the long-distance (distance in the X-axis direction) propagation of light.

[0057] In some embodiments, the vehicle headlight assembly further includes a high beam / low beam module 40, which is disposed on the light-emitting side of the second optical module 20, and in the X-axis direction, the high beam / low beam module 40 is disposed on the side of the second optical module 20 away from the first optical module 10.

[0058] That is, the high and low beam module 40 is positioned to the upper left of the second optical module 20. Figure 1 (View angle) This arrangement avoids mutual interference between the light from the high and low beam modules 40 and the second optical module 20, thus improving the overall lighting effect.

[0059] In practical applications, the second optical module 20 is installed in the part between the high and low beam module 40 and the first optical module 10, which is a reasonable structure and further enhances the versatility of vehicle lighting applications.

[0060] In some embodiments, the vehicle light assembly further includes a housing 50 and a light distribution lens 60. The housing 50 has an accommodating space, and the light distribution lens 60 covers the opening of the housing 50 to seal the accommodating space. The first optical module 10 and the second optical module 20 are accommodated in the accommodating space.

[0061] On the other hand, this application relates to a vehicle including any of the aforementioned headlight components.

[0062] The technical solution provided in this application aims to arrange the second optical module 20 on the light-incident side of the first optical module 10, with the two optical modules overlapping in their orthogonal projections on the projection plane η. This allows the second optical module 20 to utilize the space on the light-incident side of the first optical module 10, reducing the vertical space occupied by the two optical modules. While meeting the diverse usage requirements of the vehicle headlight (the two optical modules can be set as corresponding functional modules according to actual usage), it avoids occupying too much space in the headlight, which is beneficial for the arrangement of other components inside the headlight and for the flat and personalized design of the headlight.
