[0002] With the continuous development of the automotive industry and the increasing aesthetic demands of consumers, automotive lights are no longer limited to traditional functional lighting tools, but are gradually evolving towards personalization, branding, and intelligence. Correspondingly, the structure of automotive lights has become more complex, with sharper and more irregular lines. In existing technologies, mounting holes are often set in the trim ring to install thick-walled components; however, gaps can easily exist between the thick-walled component and the wall of the mounting hole, leading to light leakage, and the complexity of the trim ring's design also increases the difficulty of processing.

[0003] Therefore, improvements to existing technologies are necessary. Utility Model Content

[0004] This application aims to solve at least one of the technical problems existing in the prior art, and to provide an optical module and vehicle light.

[0006] In one embodiment, the first light guide component includes a main body and a snap-fit ​​portion. The first bracket is disposed on the main body, and the snap-fit ​​portion is spaced apart on the side of the main body away from the first bracket, so that a snap-fit ​​space is formed between the snap-fit ​​portion and the main body.

[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. 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.

[0027] 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.

[0028] The optical module and vehicle lights in this application will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] In existing technologies, mounting holes are often set on the decorative ring to install the thick-walled part in the mounting hole; however, gaps can easily exist between the thick-walled part and the wall of the mounting hole, resulting in light leakage, and the processing difficulty of the decorative ring with complex shape will also increase.

[0030] To address the aforementioned technical problems, this application provides an optical module, including a support assembly and a first light guide component. The support assembly includes a first support and a second support, which are separately configured. The first support is disposed on the side of the second support away from the ground. The first light guide component is disposed between the first support and the second support. The first support and the first light guide component are integrally formed, and the second support is detachably connected to the first light guide component. This will be described in detail below.

[0031] See Figure 1 The optical module includes a bracket assembly 10 and a first light guide component 20. The bracket assembly 10 includes a first bracket 11 and a second bracket 12, which are separately arranged. The first bracket 11 is disposed on the side of the second bracket 12 away from the ground. The first light guide component 20 is disposed between the first bracket 11 and the second bracket 12. The first bracket 11 and the first light guide component 20 are integrally arranged, and the second bracket 12 is detachably connected to the first light guide component 20.

[0032] When the bracket assembly 10 (first bracket 11 and second bracket 12) is integrated, the overall volume of the bracket assembly 10 is large and the shape is complex, which is not conducive to the overall design of the headlight and can easily lead to the instability of the bracket assembly 10 structure. In this application, by setting the first bracket 11 and the second bracket 12 separately, the volume of each component (first bracket 11 and second bracket 12) is reduced, thereby reducing the processing difficulty of each component and meeting the complex shape design of the headlight.

[0033] The first bracket 11 and the second bracket 12 are respectively disposed above and below the first light guide component 20. Figure 1 From the perspective of the two sides, the separate design facilitates installation and operation, ensures installation accuracy, and helps improve the lighting effect of the headlights; the first bracket 11 and the first light guide component 20 are integrated, which can avoid gaps between the first bracket 11 and the first light guide component 20. Moreover, the integrated design will not cause the assembly gap (the assembly gap when the first light guide component 20 and the first bracket 11 are separate) to be inconsistent due to the deformation of the parts, which helps to improve the overall appearance and prevents light leakage.

[0034] It should be noted that the first bracket 11 and the first light guide component 20 are integrally formed, which can be formed by two-color injection molding. In some embodiments, other processing methods can also be used, such as welding the first bracket 11 to connect it to the first light guide component 20 as an integral unit, etc., and it is not limited to these.

[0035] In this embodiment, the second bracket 12 is detachably connected to the first light guide component 20, that is, the second bracket 12 and the first light guide component 20 are separately set. When the second bracket 12 and the first light guide component 20 are also integrated (the first bracket 11, the second bracket 12 and the first light guide component 20 are integrated), the overall structure of the optical module is complex, which increases the processing difficulty and manufacturing cost. However, by setting the second bracket 12 and the first light guide component 20 separately, the processing difficulty of the parts can be reduced, and the entire optical module does not need to be replaced during later maintenance and repair, thus reducing the later maintenance and repair cost.

[0036] It is worth mentioning that when the optical module is installed on a vehicle, since the second bracket 12 is detachably connected to the first light guide component 20, in some embodiments there may be a gap between the second bracket 12 and the first light guide component 20. However, when observed by personnel, the second bracket 12 is positioned below the first light guide component 20, which can reduce the adverse effects of the gap.

[0037] It should be noted that the first bracket 11 is located on the side of the second bracket 12 away from the ground, that is, the first bracket 11 is located on the top of the first light guide component 20, and the second bracket 12 is located on the bottom of the first light guide component 20.

[0038] In some embodiments, the first light guide component 20 includes a main body 21 and a snap-fit ​​portion 22. A first bracket 11 is disposed on the main body 21, and the snap-fit ​​portion 22 is disposed at intervals on the side of the main body 21 away from the first bracket 11, so that a snap-fit ​​space 30 is formed between the snap-fit ​​portion 22 and the main body 21. The second bracket 12 includes a fitting portion 121 and a mounting portion 122 that are connected to each other and arranged at an angle. The mounting portion 122 is provided with a snap-fit ​​groove 1221, and the snap-fit ​​portion 22 snaps into the snap-fit ​​groove 1221, so that the fitting portion 121 snaps into the snap-fit ​​space 30.

[0039] In this embodiment, by engaging the snap-fit ​​part 22 with the snap-fit ​​groove 1221, the fitting part 121 can be snapped into the snap-fit ​​space 30, and the fitting part 121 can be tightly attached to the main body part 21, reducing the gap between the fitting part 121 and the main body part 21, which is beneficial to improving the overall appearance and preventing light leakage.

[0040] Multiple snap-fit ​​parts 22 are provided at intervals, and multiple snap-fit ​​slots 1221 are provided accordingly. This can better ensure that the fitting part 121 fits on the main body part 21, avoid gaps caused by dimensional processing errors of the second bracket 12, and make the structure simple, easy to install and use. At the same time, it helps to improve the stability of the installation between the second bracket 12 and the first light guide component 20.

[0041] See Figure 1 as well as Figure 2The contact surface between the first support 11 and the main body 21 is the first surface 40, and the contact surface between the fitting part 121 and the main body 21 is the second surface 50. The line connecting the end of the first surface 40 near the light-emitting side of the main body 21 and the end of the second surface 50 near the light-incident side of the main body 21 is a straight line a. The angle between the straight line a and the horizontal plane λ is α, which satisfies: 20°≤α≤45°, such as 20°, 25°, 30°, 40°, 45°, etc.

[0042] For ease of explanation, the end of the first surface 40 near the light-emitting side of the main body 21 is referred to as the first end, and the end of the second surface 50 near the light-incident side of the main body 21 is referred to as the second end. The value of the included angle α can reflect the difference between the first end and the second end in the lateral direction. Figure 1 The spacing size on the perspective (the same below).

[0043] When α is greater than 45°, the lateral distance between the first and second ends is smaller, and the second end is closer to the first end, meaning the second end is closer to the light-emitting end of the main body 21. Users can more easily observe the second end through the main body 21 (in actual use, the observed second end will form a black line, affecting the overall visual effect of the headlight), which is detrimental to improving the overall visual effect of the headlight. When α is less than 20°, the lateral distance between the first and second ends is larger, and the second end is more biased to the left relative to the first end. Figure 2 (View angle) Although it can avoid observing the black line (within the personnel's view angle, the second end is blocked by the first support 11), the second support 12 occupies more space laterally, which is not conducive to the overall structural layout.

[0044] Therefore, when 20°≤α≤45°, it is possible to avoid observing the second end through the main body 21 and reduce the lateral space occupied by the fitting part 121, thereby improving space utilization.

[0045] It should be noted that the personnel's field of view refers to the angle between the line of sight of a person observing the optical module when the optical module is installed on the vehicle and the horizontal plane λ when the person is standing near the vehicle. This angle is related to the distance between the observer and the vehicle.

[0046] In some embodiments, the second bracket 12 further includes a shielding portion 123, which is disposed on the side of the fitting portion 121 away from the mounting portion 122; a projection surface η is set perpendicular to the main light emission direction of the first light guide component 20, and the orthographic projection of the snap-fit ​​portion 22 on the projection surface η is located within the orthographic projection of the shielding portion 123 on the projection surface η.

[0047] By providing the shielding part 123, the shielding part 123 can be used to attach the latching part 22 (and the latching slot 1221), effectively improving the visual appearance of the optical module. It should be noted that the main light emission direction of the first light guide component 20 is as follows... Figure 1 as well as Figure 2 The direction is shown as X.

[0048] In some embodiments, the first light guide component 20 further includes a first fixing part 23, which is disposed on the side of the snap-fit ​​part 22 away from the fitting part 121; the second bracket 12 further includes a second fixing part 124, which is disposed on the side of the mounting part 122 away from the fitting part 121; the first fixing part 23 is fixedly connected to the second fixing part 124.

[0049] In this embodiment, the fixed connection between the second bracket 12 and the first light guide component 20 is achieved through the cooperation of the first fixing part 23 and the second fixing part 124. The structure is simple and easy to install and use.

[0050] In some embodiments, the first fixing part 23 and the second fixing part 124 extend in the opposite direction of direction X, which can reduce the vertical direction of the optical module ( Figure 1 The space occupied from a visual perspective is conducive to the design of a flattened headlight. In addition, the first fixing part 23 and the second fixing part 124 can be connected by fixing methods such as screws and rivets, and are not limited to these.

[0051] In some embodiments, the contact surface between the first bracket 11 and the first light guide component 20 is a stepped surface.

[0052] The stepped surface design helps to improve the stability of the connection between the first support 11 and the first light guide component 20, thereby enhancing the structural strength.

[0053] In some embodiments, the first bracket 11 and the first light guide component 20 are integrally formed by injection molding. The stepped surface can also reduce the sealing angle of the first light guide component 20, thereby increasing the utilization rate of the first light guide component 20.

[0054] In some embodiments, the optical module further includes a second light guide component 60, which is disposed at intervals on the light-incident side of the first light guide component 20; the light-emitting surface of the second light guide component 60 is a diffusion surface, and the light-incident surface of the first light guide component 20 is a converging surface.

[0055] After passing through the light-emitting surface of the second light guide component 60, the light is diffused, which helps to improve the uniformity of the light. After being diffused by the second light guide component 60, the light is converged after passing through the light-incident surface of the first light guide component 20, which avoids reducing the light flux and thus reducing the brightness. By setting the diffusion surface and the convergence surface, the brightness value of the light (high luminous efficiency) can be guaranteed, and the effect of uniform light emission of the optical module can be achieved.

[0056] In some embodiments, the light-emitting surface of the first light guide component 20 can also be configured as a diffusion surface. After the light is converged into the first light guide component 20, it is diffused out through the light-emitting surface of the first light guide component 20, which effectively improves the illumination range of the light.

[0057] In some embodiments, the first light guide component 20 is provided with a first fixing part 23, and the second bracket 12 is provided with a second fixing part 124. For specific details, please refer to the foregoing embodiments, which will not be repeated here. The first fixing part 23 and the second fixing part 124 extend in the opposite direction along the X direction, which can cover the gap between the first light guide component 20 and the second light guide component 60, and can block stray light (light that does not shine on the first light guide component 20) diffused from the light-emitting surface of the second light guide component 60, which can effectively prevent light leakage.

[0058] In the main light-emitting direction of the first light guide component 20, the distance between the second light guide component 60 and the first light guide component 20 is d, which satisfies: 9 mm ≤ d ≤ 11 mm, such as 9 mm, 10 mm, 11 mm, etc.

[0059] When the value of d is less than 9 mm, the first light guide component 20 and the second light guide component 60 are too close together, resulting in an overall brightness of the optical module that is too bright and does not soften the light. Furthermore, the close distance means that some areas of the light-incident surface of the first light guide component 20 will not receive light (the light is diffused after passing through the light-out surface of the second light guide component 60; the farther away from the light-out surface of the second light guide component 60, the larger the diffusion range, and the closer to the light-out surface of the second light guide component 60, the smaller the diffusion range. Therefore, when the first light guide component 20 and the second light guide component 60 are close together, the light-incident surface of the first light guide component 20 receives a smaller range of light), resulting in a poor overall lighting effect. When the value of d is greater than 11 mm, the two components are too far apart, and more light will be directed towards the non-illuminated areas, causing the brightness of the optical module to decrease.

[0060] In some embodiments, the light-emitting surface of the second light guide component 60 is provided with a frosted texture.

[0061] The frosted leather texture softens the light and prevents glare, while also concealing internal structural details and preventing them from showing through the printed circuit board or other non-display areas, thus enhancing the overall appearance and texture.

[0062] On the other hand, this application also relates to a vehicle light, including any of the aforementioned optical modules.

[0063] The technical solution provided in this application aims to reduce the volume of each component by separately setting the first bracket 11 and the second bracket 12, thereby reducing the processing difficulty of each component and meeting the complex shape design of the vehicle headlight. The first bracket 11 and the second bracket 12 are respectively set on the upper and lower sides of the first light guide component 20. The separate setting facilitates installation and operation, ensures installation accuracy, and helps improve the lighting effect of the vehicle headlight. The first bracket 11 and the first light guide component 20 are integrated, which can avoid gaps between the first bracket 11 and the first light guide component 20. Moreover, the integrated setting will not cause inconsistent assembly gaps due to component deformation, which helps improve the overall appearance and prevents light leakage.
