Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0033] In the description of the present application, it should be noted that, unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connecting" should be understood in a broad sense, for example, can be fixedly connected, or can be detachably connected, or integrally connected; can be mechanically connected, or electrically connected or can communicate with each other; can be directly connected, or indirectly connected through an intermediate medium; can be the internal connection of two elements or the interaction relationship between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0034] The optical module and the vehicle lamp in the present application will be described in detail below with reference to the drawings and specific embodiments.

[0035] In the prior art, in order to ensure the lighting effect after the lamp narrows, the depth cannot be shortened, so that the overall strength of the lamp cannot be ensured according to the traditional installation scheme.

[0036] In order to solve the above technical problems, the present application provides an optical module, comprising a first optical unit, a second optical unit and a support; the second optical unit is connected with the first optical unit and is arranged at an angle; the support is arranged between the included angle formed by the first optical unit and the second optical unit, and the support is connected to the first optical unit and the second optical unit respectively. The following will be described in detail.

[0037] Reference is made to Figure 1In an embodiment, the optical module comprises a first optical unit 10, a second optical unit 20 and a support 30; the second optical unit 20 is connected to the first optical unit 10 and arranged at an angle; the support 30 is arranged between the included angle formed by the first optical unit 10 and the second optical unit 20, and the support 30 is connected to the first optical unit 10 and the second optical unit 20 respectively.

[0038] In this embodiment, the first optical unit 10 and the second optical unit 20 are connected by the support 30 arranged between the first optical unit 10 and the second optical unit 20, which can effectively avoid the expansion (the parts of the first optical unit 10 and the second optical unit 20 far away from the connection point of the first optical unit 10 and the second optical unit 20 move away from each other), the contraction (the parts of the first optical unit 10 and the second optical unit 20 far away from the connection point of the first optical unit 10 and the second optical unit 20 move close to each other), the torsion and other phenomena between the first optical unit 10 and the second optical unit 20, which improves the rigidity of the whole optical module and is beneficial to the improvement of the lighting effect.

[0039] The first optical unit 10 and the second optical unit 20 are connected to each other, that is, the first optical unit 10 and the second optical unit 20 are arranged separately, which divides the optical module into multiple parts, avoids the size of a single part being too large, reduces the processing difficulty of each part, improves the dimensional accuracy of the processing of each part, and further improves the consistency of assembly.

[0040] Referring to Figure 2 and Figure 4 In an embodiment, the first optical unit 10 comprises a first reflector 11, a first light guide part 12 and a first decorative ring 13 connected in sequence, that is, the first light guide part 12 is connected between the first reflector 11 and the first decorative ring 13, and the first light guide part 12 is configured to conduct the light emitted by the first reflector 11 to the first decorative ring 13; the second optical unit 20 comprises a second reflector 21, a second light guide part 22 and a second decorative ring 23 connected in sequence, that is, the second light guide part 22 is connected between the second reflector 21 and the second decorative ring 23, and the second light guide part 22 is configured to conduct the light emitted by the second reflector 21 to the second decorative ring 23; the support 30 is connected to the first reflector 11 and the second decorative ring 23.

[0041] In this embodiment, the support 30 is connected with the first mirror 11 in the first optical unit 10 and the second mirror 23 in the second optical unit 20, and the connection positions are staggered, which is beneficial to improve the overall rigidity. When connected with the second mirror 21 in the second optical unit 20, the connection positions of the support 30 on the first optical unit 10 and the second optical unit 20 are close to the same side of the overall optical module (the connection point with the first mirror 11 is close to the light-in side of the first light guide component 12, and the connection point with the second mirror 21 is close to the light-in side of the second light guide component 22), at this time, the support 30 has no limiting effect on the light-out side of the first light guide component 12 and the second light guide component 22, in actual use, it may cause unstable connection between the first optical unit 10 and the second optical unit 20 under the influence of external force, vibration and the like, and further affect the lighting effect of the optical module.

[0042] It should be noted that in some embodiments, the support 30 can of course also be connected to the first mirror 11 and the second mirror 21, and the light-out side of the first mirror 11 and the second mirror 21 can be reinforced by other connection methods, or even in some embodiments, other connection methods can not be added, and it is not limited to this. In addition, the decorative ring (the first decorative ring 13 and the second decorative ring 23) includes a transparent part and a non-transparent part arranged on the side of the transparent part, the transparent part is used for light transmission to ensure that the light of the optical module passes smoothly, and the non-transparent part can shield the internal mounting structure 60 and defects to improve the quality of the vehicle lamp in static state.

[0043] Referring to Figure 6 In some embodiments, the first light guide component 12 is covered on the light-out port of the first mirror 11 by the mounting structure 60, which is arranged on the edge of the light-out port of the first mirror 11 and can be connected by the cooperation of the buckle 61 and the clamping block 62, and the mounting structure 60 is arranged on the surface of the first light guide component 12 facing the first mirror 11 (i.e. the light-in surface of the first light guide component 12), the first light guide component 12 has a shielding effect on the mounting structure 60, and the mounting structure 60 cannot be seen from the light-out side of the first light guide component 12 in the static state of the vehicle lamp, thereby improving the quality of the vehicle lamp in the static state; and the mounting structure 60 does not occupy the space on the side of the first light guide component 12, which is beneficial to the design of the vehicle lamp to meet the individualized design requirements.

[0044] It should be noted that the connection between the second mirror 21 and the second light guide component 22 in the second optical unit 20 can also be connected by the mounting structure 60, which will not be described here.

[0045] Referring to Figure 7 and Figure 8In one embodiment, a first reflector 11 is disposed on a mounting surface. The first reflector 11 includes a plurality of first reflective sub-parts 111. The first reflective sub-parts 111 are configured to reflect light incident on the first reflective sub-parts 111 to the light-emitting side of the first reflector 11. The first reflective sub-parts 111 located at both ends of the first reflector 11 are an initial sub-part 111a and an end sub-part 111b. From the initial sub-part 111a to the end sub-part 111b, the orthographic projection of the angle between the principal optical axis of each first reflective sub-part 111 and the principal optical axis of the initial sub-part 111a on the mounting surface gradually increases.

[0046] The angle between the principal optical axis of each first reflector sub-section 111 and the principal optical axis of the initial sub-section 111a gradually increases on the orthographic projection onto the mounting surface. This ensures that the energy emitted by the first reflector 11 at various angles is nearly uniform, preventing the light emitted by the first reflector 11 in a single direction from becoming too concentrated. At the same time, since different first reflector sub-sections 111 emit light in different directions, the irradiance in each direction will not differ significantly. This results in a consistent viewing effect when viewing the lamp from different angles, achieving uniformity of multi-angle observation when the headlights are on and improving the display quality of the headlights.

[0047] The angle between the principal optical axis of each first reflective sub-part 111 and the principal optical axis of the initial sub-part 111a gradually increases on the orthographic projection onto the mounting surface. This means that the light reflected by each first reflective sub-part 111 will not interfere with each other, which is beneficial to improving the lighting effect of the headlights.

[0048] In some embodiments, the orthographic projection of the angle between the principal optical axes of two adjacent first reflective sub-parts 111 on the mounting surface is a fixed value. That is, from the initial sub-part 111a to the final sub-part 111b, the orthographic projection of the angle between the principal optical axis of each first reflective sub-part 111 and the principal optical axis of the initial sub-part 111a on the mounting surface increases by the same amount, making the overall structure of the first reflective mirror 11 more uniform and facilitating the processing and shaping of the first reflective mirror 11. In some embodiments, the angle can be increased to different degrees, and the relevant angles can be set according to factors such as the actual shape of the first reflective mirror 11.

[0049] It should be noted that the principal optical axis of the initial sub-part 111a is as follows: Figure 7 As shown by the middle straight line c, the principal optical axis of the last sub-part 111b is as follows: Figure 7 As shown by the straight line d. The mounting surface η is the base surface of the carrier on which the first reflector 11 is positioned and fixed. For example, when the first reflector 11 is mounted on the carrier surface of the heat sink, the carrier surface of the heat sink is the mounting surface. In some embodiments, the mounting surface η can also be set as... Figure 8The upper side of the first mirror 11 in the visual angle is not limited to this according to the specific installation mode of the first mirror 11. Similarly, the second mirror 21 can also be arranged as the first mirror 11, which will not be described here.

[0050] In an embodiment, the support 30 is provided with two connection positions with the first mirror 11, and one connection position with the second decorative ring 23, and the three connection positions are arranged in a triangular shape.

[0051] In the embodiment, by arranging the connection positions of the support 30 with the first mirror 11 and the second decorative ring 23 at the three corners of the triangle, the triangular structure is stable, which is conducive to improving the overall rigidity; and there are three connection positions in total, which can avoid occupying more internal space and provide sufficient arrangement and installation space for other components, and only three installation connections are needed to realize the improvement of the overall rigidity of the optical module, which is conducive to improving the assembly efficiency.

[0052] In some embodiments, the number of connection positions can also be four, five, etc., which is comprehensively considered according to the product model, size and other factors during actual use, and is not limited to this; the connection mode between the support 30 and the first mirror 11 and between the support 30 and the second decorative ring 23 can be screw connection, bolt pair connection, riveting and other connection modes, which is not specifically limited here, and the selection of the relevant connection mode is made according to the actual production needs.

[0053] Referring to Figure 3 In an embodiment, the end of the second decorative ring 23 close to the first optical unit 10 is connected with the end of the first light guide component 12 close to the second optical unit 20.

[0054] In the embodiment, by connecting the ends of the second decorative ring 23 and the first light guide component 12 close to each other, the connection between the first optical unit 10 and the second optical unit 20 is realized, and the overall strength of the optical module is improved.

[0055] The first mirror 11, the first light guide component 12 and the first decorative ring 13 in the first optical unit 10 are connected to form an integral whole; similarly, the components in the second optical unit 20 are also connected to form an integral whole; in the embodiment, the first optical unit 10 and the second optical unit 20 are preliminarily connected by connecting the second decorative ring 23 with the first light guide component 12 during installation, and then the first optical unit 10 and the second optical unit 20 are finally connected by connecting the support 30 with the first mirror 11 and the second decorative ring 23; the second decorative ring 23 is connected with the first light guide component 12, the first light guide component 12 is connected with the first mirror 11, the first mirror 11 is connected with the support 30, and the support 30 is connected with the second decorative ring 23, so that the components are limited with each other, which is conducive to improving the overall rigidity and connecting the components to form an integral whole, thereby improving the quality of the vehicle lamp.

[0056] In some embodiments, the second decorative ring 23 can be connected with the first mirror 11, but such connection cannot guarantee the stability between the second decorative ring 23 and the first light guide component 12 when an external force or vibration during use acts; in the embodiment, the second decorative ring 23 is connected with the first light guide component 12, which can guarantee the stability of the connection between the two, and the connection through the support 30 (see the foregoing analysis) is conducive to improving the overall rigidity.
