Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0027] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0028] As described in the background section, current installations of light guides require the addition of fixing structures on both sides of the light guide, which affects the uniformity of light output and the loss of light transmission, leading to appearance defects and increased energy consumption.

[0029] To solve the above problems, please refer to Figures 1 to 3This application provides a light guide mounting structure 10, including a first light guide bracket 11, the first light guide bracket 11 having a first arc surface 111 in contact with the circumferential surface of the light guide 20; and a second light guide bracket 12, the second light guide bracket 12 having a second arc surface 121 in contact with the circumferential surface of the light guide 20; wherein, the first light guide bracket 11 and the second light guide bracket 12 are fixedly connected, and the first arc surface and the second arc surface are arranged sequentially around the circumference of the light guide, and the first arc surface 111 and the second arc surface 121 cooperate to clamp the light guide 20.

[0030] For details, please refer to Figure 2 After the first light guide bracket 11 and the second light guide bracket 12 are connected together, the first arc surface 111 and the second arc surface 121 are arranged sequentially around the circumference of the light guide. The first arc surface 111 and the second arc surface 121 work together to clamp the light guide 20. The structure is simple and does not require any other fixing structure. It can ensure that the light guide 20 is firmly installed without obstructing the light guide 20, thus not affecting the uniformity of the light emitted from the light guide 20, and without losing light energy.

[0031] In some embodiments, the first arc surface 111 and the second arc surface 121 are respectively bonded to the circumferential surface of the light guide 20 by ribs.

[0032] Theoretically, a perfect fit between the light guide 20 and the first arc surface 111 and the second arc surface 121 is optimal. However, due to manufacturing errors, a perfect fit is impossible, and gaps will inevitably exist between the surfaces. During use, vibration and friction occur due to these gaps, generating dust, which not only affects the appearance but can also lead to product failure over time. To avoid these problems, the first arc surface 111 and the second arc surface 121 can be designed to fit the light guide 20 with ribs. That is, top ribs are provided on the side of the first arc surface 111 and the second arc surface 121 closest to the light guide 20. The top surface of the top ribs is in close contact with the circumferential surface of the light guide. Because the top surface area of ​​the top ribs is small, the compressive pressure on the circumferential surface of the light guide can be increased under the same clamping force, thereby allowing the light guide 20 to be more securely fixed.

[0033] In some embodiments, please refer to Figure 3 The first arc surface 111 and / or the second arc surface 121 have sinusoidally varying peaks and troughs.

[0034] The first arc surface 111 and the second arc surface 121 have sinusoidally gradient peaks and troughs. The peaks contact the light guide 20, achieving line-to-surface contact and clamping the light guide 20. The troughs do not contact the light guide 20. Since the troughs are smooth, gradient surfaces without abrupt changes, even after light reflection, the uniformity of light emitted from the light guide 20 will not be affected. Therefore, in this embodiment, the first arc surface 111 and the second arc surface 121 are designed as sinusoidally gradient surfaces, which can both lock the light guide 20 and not affect its uniformity.

[0035] In some embodiments, the first light guide bracket 11 includes a first connecting portion 112, and the second light guide bracket 12 includes a second connecting portion 122; wherein the first connecting portion 112 and the second connecting portion 122 are connected by screws or by thermal riveting.

[0036] Please continue to refer to this. Figure 2 The first connecting part 112 and the second connecting part 122 can be connected by screws or by thermal riveting. Since the first connecting part 112 and the second connecting part 122 do not directly contact the light guide 20, but mainly serve as a fixed connection, other common connection methods can also be used, and this application does not limit them.

[0037] In some embodiments, please refer to Figure 1 and Figure 3 The lengths of the first optical guide bracket 11 and the second optical guide bracket 12 are equal to the length of the optical guide 20.

[0038] For example, the light guide 20 can be a cylinder, with the first arc surface 111 and the second arc surface 121 contacting the circumferential curved side surface of the light guide 20. By designing the lengths of the first light guide bracket 11 and the second light guide bracket 12 to be equal to the length of the light guide 20, more comprehensive support can be provided for the light guide 20, making the installation of the light guide 20 more stable.

[0039] In some embodiments, please refer to Figure 2 and Figure 3 The first arc surface 111 and the second arc surface 121 are spliced ​​together to form a third arc surface, which has a sinusoidal gradient surface.

[0040] Specifically, the first arc surface 111 and the second arc surface 121 are closely connected to form the third arc surface. The area of ​​the third arc surface is the sum of the areas of the first arc surface 111 and the second arc surface 121. The third arc surface has a sinusoidally gradient surface; specifically, it has sinusoidally gradient crests and troughs. The crests contact the light guide 20, achieving line-surface contact and clamping the light guide 20. The troughs do not contact the light guide 20. Because the troughs are gradually curved surfaces, even after light reflection, the uniformity of light emitted from the light guide 20 will not be affected. The third arc surface can both lock the light guide 20 in place and maintain the uniformity of light emitted from the light guide 20.

[0041] In some embodiments, the third arc surface contacts the side surface of the light guide 20 and covers at least half of the side surface area of ​​the light guide 20.

[0042] Using a cylindrical light guide 20 as an example, the light guide 20 has a curved side surface, and a third arc surface covers at least half of the area of ​​this curved side surface. For a more intuitive explanation, please refer to [reference needed]. Figure 1 and Figure 2 , Figure 2 for Figure 1 The cross-sectional view of the structure shown along the dashed line AA, from Figure 2 As can be seen, the cross-section of the light guide 20 is circular, and the circumference of this circle is C. The third arc surface is... Figure 2 The curve is represented as an arc with a length of L, where L ≥ C / 2.

[0043] Furthermore, the third arc surface covers at least the lowest point of the light guide 20. In this way, the light guide mounting structure 10 can not only provide clamping force for the light guide 20, but also provide support force for the light guide 20 from below, making the fixation of the light guide 20 by the light guide mounting structure 10 more reliable.

[0044] This application also discloses an optical guide component, please refer to... Figure 1 and Figure 2 The light guide assembly includes a light guide 20 and a light guide mounting structure 10 as described in any of the above embodiments.

[0045] The aforementioned light guide assembly has a simple structure, is firmly installed, and does not affect the uniformity of light output from the light guide 20.

[0046] In some embodiments, the light guide 20 has a cylindrical structure.

[0047] The light guide 20, with its cylindrical structure and curved sides, can fit snugly against the first arc surface 111 and the second arc surface 121 of the light guide mounting structure 10, achieving a secure installation. Furthermore, both the first arc surface 111 and the second arc surface 121 are gradient curved surfaces, which can achieve a uniform light effect.

[0048] This application also discloses a vehicle light, including the light guide component described in the above embodiments.

[0049] The aforementioned vehicle headlights utilize the light guide components described in the preceding embodiments, which can simplify the structure, enhance the aesthetics of the headlights, and simultaneously ensure good light uniformity and reduce energy consumption.

Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.

[0051] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description.
