[0005] The reflector includes:

[0006] reflective ontology;

[0007] A cover fitting part is provided at the front end of the reflective body along the light emission direction. The cover fitting part covers the lens and is inserted into the surface of the lens.

[0008] In some embodiments, the cover mating part is provided with a square positioning groove that extends through its inner and outer surfaces, and the lens is provided with a positioning plate on the side near the cover mating part. The positioning plate is shaped to match and is inserted into the square positioning groove.

[0009] In some embodiments, a groove is provided on the inner surface of the cover fitting portion near the lens, the groove matching the surface contour shape of the adjacent lens to accommodate at least a portion of the lens.

[0010] In some embodiments, the wall thickness of different parts of the covering mating portion is the same, or the difference in wall thickness of different parts of the covering mating portion does not exceed 1 mm.

[0011] In some embodiments, the optical module further includes a carrier disposed on the end face of the lens away from the cover mating part, and the bearing surface of the carrier is provided with a groove that conforms to the contour of the end face of the lens for fitting and accommodating the end face of the lens.

[0012] In some embodiments, in the vertical direction along which the lens and the cover are assembled in sequence, the height of the lens is greater than the height of the inner reflecting surface of the reflecting body;

[0013] The wall thickness of different parts of the covering mating part is the same or the wall thickness difference does not exceed 1 mm, and the covering mating part is connected to the reflective body through a stepped structure.

[0014] According to another aspect of this application, a vehicle lamp is provided, including any of the optical modules described above.

[0015] According to another aspect of this application, a vehicle is provided, including the aforementioned vehicle lights.

[0016] The aforementioned optical module has at least the following beneficial technical effects:

[0017] The cover unit covers the lens from above, which on the one hand prevents light from leaking out of the lens surface; on the other hand, it limits the lens from above, restricts the lens's displacement in the vertical direction, reduces the lens's violent vertical vibration with the vehicle during use, and helps to ensure the stability of the position and shape of the emitted light pattern.

[0018] After the cover fitting part is inserted and fitted with the surface of the lens, the relative position between the lens and the reflector in the horizontal direction can be directly restricted. The relative position between the two is stable, which helps to ensure the light emission accuracy and, overall, helps to improve the stability of the position and shape of the emitted light pattern.

[0019] The mating design in this embodiment eliminates the need for fasteners such as bolts, thus avoiding structural weakening caused by drilling screw holes. It also achieves stability comparable to traditional fastening methods through multi-dimensional constraints, while retaining the advantages of lightweight and efficient assembly.

[0042] In the assembly process of headlight modules, the installation of the lens is a crucial step, as its installation accuracy affects the headlight's lighting performance and driving safety. Currently, lens installation methods often use bolts or clips, and the complex installation structure directly increases the assembly difficulty and time cost.

[0043] refer to Figures 1-7 This application provides an optical module, including a reflector 11 and a lens 12 arranged sequentially along the light emission direction, wherein the reflector 11 is configured to reflect light emitted by a light source;

[0044] The reflector 11 includes:

[0045] reflective body 11a;

[0046] The cover fitting part 11b is provided at the front end of the reflective body 11a along the light emission direction. The cover fitting part 11b covers the lens 12 and is inserted into the surface of the lens 12.

[0047] Specifically, the reflector 11 can focus the light emitted by the light source into a preset direction and illuminate the lens 12, thereby presenting a preset light pattern, such as high beam or low beam.

[0048] The cover part 11b covers the lens 12 from above, which can prevent light from leaking out of the surface of the lens 12. On the other hand, it limits the lens 12 from above, restricts the displacement of the lens 12 in the vertical direction, reduces the violent vertical vibration of the lens 12 with the vehicle during vehicle use, and helps to ensure the stability of the position and shape of the light output pattern.

[0049] After the cover fitting part 11b is inserted and fitted with the surface of the lens 12, the relative position between the lens 12 and the reflector 11 in the horizontal direction can be directly restricted. The relative position between the two is stable, which is conducive to ensuring the light emission accuracy and overall helps to improve the stability of the position and shape of the emitted light pattern.

[0050] The mating design in this embodiment eliminates the need for fasteners such as bolts, thus avoiding structural weakening caused by drilling screw holes. It also achieves stability comparable to traditional fastening methods through multi-dimensional constraints, while retaining the advantages of lightweight and efficient assembly.

[0051] refer to Figures 2-5 , Figure 7 In some embodiments, the cover fitting part 11b is provided with a square positioning through groove 11d that extends through its inner and outer surfaces, and the lens 12 is provided with a positioning plate 12c on the side near the cover fitting part 11b. The positioning plate 12c is shaped and interlocked with the square positioning through groove 11d.

[0052] Specifically, when the positioning plate 12c and the square positioning slot 11d are matched and inserted, the relative positions of the lens 12 and the reflector 11 in the horizontal direction can be directly restricted. The stable relative positions of the two are conducive to ensuring the light emission accuracy and, overall, to improving the stability of the position and shape of the emitted light pattern.

[0053] Secondly, the positioning plate 12c and the square positioning slot 11d are shaped and interlocked, which can prevent the lens 12 from rotating relative to the reflector 11 in the horizontal plane; and the covering part 11b can effectively limit the displacement of the lens 12 in the vertical direction through the blocking effect.

[0054] The mating design in this embodiment eliminates the need for fasteners such as bolts, thus avoiding structural weakening caused by drilling screw holes. It also achieves stability comparable to traditional fastening methods through multi-dimensional constraints, while retaining the advantages of lightweight and efficient assembly.

[0055] It is worth noting that in this embodiment, the square positioning slot 11d and the positioning plate 12c are used as examples to describe the insertion and mating method of this application. In other embodiments, other insertion and mating methods can also be used, such as the mating method of the plug and the socket. This application does not limit this.

[0056] refer to Figure 2 , Figure 7 The inner surface of the cover fitting part 11b near the lens 12 is provided with a groove 11c, the groove 11c matching the surface contour shape of the adjacent lens 12, so as to accommodate at least part of the lens 12.

[0057] For example, when the lens 12 includes an inner lens unit 12a and an outer lens unit 12b arranged sequentially along the light-emitting direction, taking the cooperation between the inner lens unit 12a and the cover fitting part 11b as an example: the groove 11c of the inner lens unit 12a and the cover fitting part 11b are shaped to match, thereby achieving fitting assembly. On the one hand, compared to a simple vertical arrangement, when the two are fitted together in the vertical direction, it is beneficial to reduce the size of the mating assembly formed by the inner lens unit 12a and the cover mating part 11b in the vertical direction. This is beneficial to reduce the size of the entire optical module in the vertical direction. When installed inside the lamp, it occupies less space inside the lamp and the arrangement is more flexible. Especially in the context of current intelligent vehicle lights, the lamp integrates more functions, and a smaller optical module can reduce the layout difficulty of the internal structure of the entire lamp. On the other hand, when the inner lens unit 12a and the groove 11c of the cover mating part 11b are matched and fitted together, the groove 11c can directly restrict the spatial position of the inner lens unit 12a, making the spatial position of the lens 12 stable. The stable relative position between the two is also beneficial to ensure the light emission accuracy. Overall, it is beneficial to improve the stability of the position and shape of the emitted light pattern.

[0058] refer to Figure 2 The wall thickness of different parts of the covering mating part 11b is the same, or the difference in wall thickness of different parts of the covering mating part 11b does not exceed 1 mm.

[0059] In this embodiment, given that the inner lens unit 12a and the groove 11c of the cover mating part 11b are shaped and matched, this arrangement can further reduce the size of the mating assembly formed by the inner lens unit 12a and the cover mating part 11b in the vertical direction. This will reduce the size of the entire optical module in the vertical direction, and when installed inside the lamp, it will occupy less space inside the lamp and be more flexible in its arrangement. Especially in the context of current intelligent vehicle lights, more functions are integrated inside the lamp, and a smaller optical module can significantly reduce the layout difficulty of the internal structure of the entire lamp.

[0060] refer to Figure 2 , Figure 6 In some embodiments, the optical module further includes a carrier 13 disposed on the end face of the lens away from the cover mating part 11b, and the bearing surface of the carrier 13 is provided with a groove 13a that conforms to the contour of the end face of the lens for fitting and accommodating the end face of the lens.

[0061] For example, the carrier 13 can be a heat sink, capable of supporting the light source plate 14 (which is used to project light onto the reflector 11) that is optically matched with the reflector 11. The end face of the lens 12 away from the cover fitting part 11b is fitted into the groove 13a. The groove 13a can restrict the spatial position of the lens 12 in the horizontal plane, which is beneficial for fixing the lower position of the lens 12 and ensuring the light emission accuracy. Furthermore, the groove 13a and the groove 11c of the upper cover fitting part 11b work together to form a bidirectional positioning in the vertical direction, which can effectively restrict the displacement and tilt of the lens 12 in the vertical direction.

[0062] refer to Figure 2 In some embodiments, in the vertical direction along which the lens 12 and the cover fitting part 11b are assembled in sequence, the height of the lens 12 is greater than the height of the inner reflecting surface of the reflecting body 11a.

[0063] The wall thickness of different parts of the covering mating part 11b is the same or the difference in wall thickness does not exceed 1 mm, and the covering mating part 11b is connected to the reflective body 11a through a stepped structure.

[0064] Specifically, with Figure 2 Taking the cooperation between the inner lens unit 12a and the cover fitting part 11b as an example: the height of the inner lens unit 12a is greater than the height of the reflective body 11a, which is beneficial to collect more light from the reflective body 11a in the height direction and can avoid the light from the reflective body 11a from leaking out and causing stray light.

[0065] With the height of the inner lens unit 12a greater than the height of the inner reflecting surface of the reflective body 11a, different parts of the cover fitting part 11b are designed with equal wall thickness and connected to the reflective body 11a via a stepped structure. This eliminates the need for a smooth connection to the outer contour surface of the reflective body 11a, thus avoiding raising the outer contour surface of the reflective body 11a to the same height as the outer surface of the cover fitting part 11b. This prevents increasing the vertical thickness of the reflective body 11a and saves on material costs. In actual manufacturing, the above-described structure in this embodiment can be formed using bending or stamping processes.

[0066] Furthermore, by adopting a stepped structure for connection, the overall space occupied by the component formed by lens 12 and reflector 11 can be further reduced. This will reduce the size of the entire optical module, and when installed inside the lamp, it will occupy less space inside the lamp and be more flexible in its arrangement. Especially in the context of current intelligent vehicle lights, more functions are integrated inside the lamp, and a smaller optical module can significantly reduce the layout difficulty of the internal structure of the entire lamp.

[0067] Of course, in other embodiments, with the inner lens unit 12a having a large height, the cover fitting part 11b can also be directly and smoothly connected to the reflective body 11a. In this case, there is no need to design a stepped structure, but the mirror body thickness of the reflector 11 needs to be designed to be very large to match the large height of the inner lens unit 12a and the cover fitting part 11b. Obviously, this would require more profile material and the overall space occupied would be larger.

[0068] This application also provides a vehicle light, including the optical modules described above, wherein each optical module can be configured as follows: Figure 1 As shown, they are arranged side-by-side along the width of the vehicle. Each optical module emits light either together or independently, thus enabling the headlights to display the desired light pattern.

[0069] This application also provides a vehicle including the headlights described above.
