[0002] The lens module of automotive lighting fixtures is generally composed of an outer lens, a lens bracket and a light-shaped structure. The light-emitting surface of the outer lens is usually not allowed to be changed. Due to the geometric properties and material characteristics of the outer lens, the sun's rays will be refracted through the light-emitting surface of the outer lens and the light-entering surface and converged in a specific area of ​​the lens bracket, which will cause ablation risk and reduce the performance of the lens module. In order to prevent the risk of ablation of the lens bracket, metal parts such as stamped galvanized plates are usually used.

[0003] Traditionally, metal parts and optical structures adopt a split structure, which requires the metal parts and optical structures to be positioned and installed separately, resulting in a more complicated installation process of the lens module and lower assembly accuracy. At the same time, there are more parts during assembly and the cost is higher.

[0004] Therefore, how to reduce the installation process while ensuring the performance of the lens module has become a technical problem that needs to be solved urgently by those skilled in the art. Utility Model Content

[0040] The core of the utility model is to provide a lens module to reduce the installation process while ensuring the performance of the lens module.

[0041] Another core of the present invention is to provide a lighting fixture having the lens module.

[0042] Another core of the utility model is to provide a vehicle with the above-mentioned lighting fixture.

[0043] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0044] The lens module of the automotive lighting fixture is generally composed of an outer lens 200, a lens holder 100 and a light-shaped structure, wherein the light-emitting surface of the outer lens 200 is usually not allowed to be changed. Due to the geometric properties and material characteristics of the outer lens 200, the sunlight will be refracted through the light-emitting surface of the outer lens 200 and the light-entering surface and converged in a specific area of ​​the lens holder 100. Figure 8 As shown, the sunlight is refracted by the light exiting surface and the light incident surface of the outer lens 200 and converges on the lens holder 100 to form a focusing area 102 on the lens holder 100. At the same time, since the lens holder 100 is generally made of plastic material, if the focusing temperature of this area is greater than the high temperature resistance limit of the lens holder 100 material, ablation risk may occur, resulting in reduced performance of the lens module. In order to prevent the risk of ablation of the lens holder 100, metal parts such as stamped galvanized plates are usually used.

[0045] Traditionally, metal parts and optical structures adopt a split structure, which requires the metal parts and optical structures to be positioned and installed separately, resulting in a more complicated installation process of the lens module and lower assembly accuracy. At the same time, there are more parts during assembly and the cost is higher.

[0046] As modern cars continue to pursue higher performance and appearance of headlights, it is necessary to improve assembly accuracy, reduce installation procedures and reduce costs while ensuring headlight performance.

[0047] For this reason, Figure 1 and Figure 2 As shown, the embodiment of the utility model discloses a lens module, including a lens bracket 100, an outer lens 200 and an optical component 300. By connecting and fixing the optical component 300, which is integrally provided with an optical baffle 301 and an ablation component 302, to the lens bracket 100, the sunlight is blocked from being refracted from the outer lens 200 to the lens bracket 100, thereby ensuring the performance of the lens module. In addition, by simply connecting and fixing the optical component 300 to the lens bracket 100, the positioning and installation of the optical baffle 301 and the ablation component 302 can be achieved at the same time, thereby reducing the installation process of the lens module, improving the assembly accuracy, reducing the number of parts required for assembly, and reducing the cost.

[0048] The following will be combined Figures 1 to 10 The lens module disclosed in the embodiment of the utility model is specifically explained and illustrated.

[0049] Among them, Figure 1 and Figure 2As shown, the outer lens 200 is arranged on the lens holder 100, and the optical component 300 includes an integrally arranged optical baffle 301 and an ablation component 302. The optical baffle 301 can effectively block and gather light to improve the lighting effect. In addition, the optical component 300 is connected to the lens holder 100, and the ablation component 302 is ensured to be located in the focusing area 102 of the outer lens 200 to block the sunlight from being refracted from the outer lens 200 to the lens holder 100, so as to avoid the risk of ablation of the lens holder 100 at the position of the focusing area 102, thereby affecting the performance of the lens module. Since the optical component 300 is integrally provided with the optical baffle 301 and the ablation component 302, during assembly, it is only necessary to connect and fix the optical component 300 to the lens holder 100, so as to realize the positioning and installation of the optical baffle 301 and the ablation component 302 at the same time, thereby reducing the installation process of the lens module, improving the assembly accuracy, and reducing the number of parts required for assembly, thereby reducing the cost.

[0050] In a specific embodiment, if Figure 3 and Figure 4 As shown, the light-type baffle 301 is made of 0.1mm and 0.5mm metal plates riveted or laser welded, and the two are combined and then riveted with the ablation part 302 to form the light-type component 300. The ablation part 302 can be a metal part such as a stamped galvanized plate, which is not limited in this article. At the same time, in order to avoid the light-type baffle 301 being deformed due to excessive riveting force when the light-type baffle 301 is riveted with the ablation part 302, thereby affecting the lighting effect of the car light, a local gap is reserved at the riveting position of the light-type baffle 301 and the ablation part 302. In this embodiment, the reserved gap can be 0.5mm.

[0051] Further, the outer lens 200 may adopt but is not limited to a light-emitting surface opening diameter of 60 mm, and the material of the outer lens 200 may adopt but is not limited to HK51 glass. In order to ensure that the appearance surface of the outer lens 200, i.e., the light-emitting surface, remains unchanged, the curvature radius of the light-incident surface of the outer lens 200 according to optical requirements is 250 mm. After secondary refraction of light at different angles, a focusing area 102 will be formed on the lens holder 100, such as Figure 8 By arranging the ablation element 302 at the position of the light focusing area 102 of the outer lens 200, the ablation element 302 blocks the light focusing area 102 formed by the secondary refraction of the light on the lens holder 100, thereby preventing the sunlight from being refracted through the light exiting surface and the light incident surface of the outer lens 200 and converging on the lens holder 100 to cause ablation, thereby improving the performance of the lens module, as shown in FIG. Fig. 9 shown.

[0052] Furthermore, if Figure 2 and Figure 6As shown, the lens holder 100 is a cylindrical structure. Among them, the lens holder 100 has a through mounting cavity 101, and the lens holder 100 has two oppositely arranged ends. For the convenience of understanding, the two ends of the lens holder 100 are defined as a first end and a second end, respectively. Among them, the inner diameter of the first end of the lens holder 100 is smaller than the inner diameter of the second end of the lens holder 100. The outer lens 200 is arranged at the first end of the lens holder 100, and the outer diameter of the opening side of the outer lens 200 is larger than the inner diameter of the first end of the lens holder 100 to prevent the outer lens 200 from escaping from the first end of the lens holder 100, and the outer lens 200 is snap-connected with the first end of the lens holder 100. The optical component 300 is located in the mounting cavity 101 and is connected to the second end of the lens holder 100 by a fastener.

[0053] Furthermore, if Figure 3 and Figure 4 As shown, the ablation component 302 includes an ablation bottom plate 3021 and ablation side plates 3022 located on both sides of the ablation bottom plate 3021. The ablation bottom plate 3021, the ablation side plates 3022 and the light-type baffle 301 are arranged to form a light-type component 300 with openings at both ends. In this embodiment, in order to facilitate the riveting fixation of the light-type baffle 301 and the ablation component 302, an extended edge is bent inward on the ablation side plate 3022 to increase the connection area between the ablation side plate 3022 and the light-type baffle 301, thereby improving the convenience of fixing the light-type baffle 301 and the ablation component 302 by riveting. At the same time, in order to ensure that the ablation component 302 completely blocks the focusing area 102 formed by the secondary refraction of light on the lens bracket 100, the ablation component 302 is provided with a shielding portion 3028 on the side of the focusing area 102 facing the outer lens 200. Specifically, the shielding portion 3028 is arranged on the ablation base plate 3021 and close to the side of the outer lens 200. At the same time, the shielding portion 3028 is arranged toward the focusing area 102 side of the outer lens 200 to completely block the focusing area 102 formed by the secondary refraction of light on the lens holder 100, thereby avoiding the risk of ablation on the lens holder 100. In addition, the shielding portion 3028 can play a role in shielding the visible features on the light-emitting element 600, such as the lettering, screws or circuits on the light board, to avoid the visible features from being exposed. Among them, the shielding portion 3028 adopts an arc plate so that the shielding portion 3028 can be completely fitted with the inner wall of the lens holder 100, thereby avoiding the secondary refraction of light on the lens holder 100. In addition, the shielding portion 3028 can be integrally formed with the ablation part 302, or a split structure can be adopted and welded to the ablation base plate 3021, which is not limited in this article.

[0054] The installation method of the optical component 300 needs to meet the requirements of static strength and fatigue strength and avoid powder discharge during vibration. At the same time, it needs to ensure that the cutoff line does not shake during driving, affecting the lighting effect, and that the ablation component 302 is completely blocked in the focusing area 102, such as Figure 5Wherein, α is the offset angle of the light-shaped baffle 301 , h1 is the offset height of the cut-off line, and h2 is the light-focusing area 102 not covered by the ablation element 302 .

[0055] For this reason, Figure 3 , Figure 6 and Figure 7 As shown, in a specific embodiment, by connecting one end of the optical component 300 to the second end of the lens bracket 100 through a fastener, and limiting the other end of the optical component 300, the optical component 300 is prevented from shaking when the vehicle is driving. Specifically, the ablation side plate 3022 has a fixed end 3023 and a free end 3025 arranged opposite to each other, and the fixed end 3023 of the ablation side plate 3022 is provided with a connecting portion 3024 connected to the second end of the lens bracket 100, so that the connecting portion 3024 of the ablation side plate 3022 is fixed to the second end of the lens bracket 100 by screws. At the same time, a limiting groove 3026 is provided at the free end 3025 of the ablation side plate 3022, and a limiting protrusion 1011 cooperating with the limiting groove 3026 is provided on the inner wall of the mounting cavity 101 of the lens bracket 100. During assembly, the optical component 300 is extended into the mounting cavity 101 of the lens bracket 100, and at the same time, the limiting groove 3026 of the ablation side plate 3022 is inserted into the limiting protrusion 1011 on the inner wall of the mounting cavity 101 of the lens bracket 100, so that the limiting groove 3026 cooperates with the limiting protrusion 1011 to limit the optical component 300, and the connecting part 3024 of the ablation side plate 3022 is fixed to the second end of the lens bracket 100 by screws, thereby achieving the fixation of both ends of the optical component 300, avoiding the optical component 300 from shaking and deviating when the vehicle is driving.

[0056] Furthermore, if Figure 2 As shown, the lens module also includes a concentrator 400, a heat sink 500 and a light emitting element 600. The concentrator 400 and the heat sink 500 are connected by fasteners, the light emitting element 600 is pressed between the concentrator 400 and the heat sink 500, and a thermal conductive adhesive 501 is filled between the light emitting element 600 and the heat sink 500. Specifically, the concentrator 400 adopts an inner lens, and the light emitting element 600 adopts an LED light board. Among them, the concentrator 400 and the heat sink 500 are connected by screws and the light emitting element 600 is pressed at the same time, and a thermal conductive adhesive 501 is filled between the light emitting element 600 and the heat sink 500 to ensure that the light emitting element 600 transfers heat to the heat sink 500 better and discharges it to the external environment through the heat sink 500.

[0057] Furthermore, if Figure 2As shown, the heat sink 500 is connected to the second end of the lens bracket 100 by screws, so that the concentrator 400 and the light emitting element 600 are located in the mounting cavity 101 of the lens bracket 100. At the same time, since some features of the light emitting element 600 are exposed at the opening of the light type component 300, in order to ensure the appearance requirements, that is, it is required that the visible features on the light emitting element 600, such as the lettering, screws or circuits on the lamp board, cannot be seen from the outside of the outer lens 200, in this embodiment, as shown in FIG. Fig.10 As shown, a shield 3027 for shielding the light emitting element 600 is provided on the ablation member 302. Specifically, the shield 3027 is provided on the ablation base plate 3021 and close to the side of the light emitting element 600. At the same time, the shield 3027 can be integrally formed with the ablation member 302, or can be a split structure and welded on the ablation base plate 3021, which is not limited herein.

[0058] Further, for ease of understanding, the shield 3027 has a free side and a connection side that are relatively arranged, and the connection side of the shield 3027 is connected to a side of the ablation base plate 3021 close to the light emitting element 600. In order to reduce the loss of light and improve the lighting effect, as shown in FIG. Figure 3 As shown, a bending portion 3029 is provided on the free side of the shielding plate 3027 and is arranged parallel to the light-shaped baffle 301 to improve the shielding effect of the shielding plate 3027 and prevent the visible features on the light-emitting element 600 from being exposed. At the same time, a trapezoidal notch is provided on the bending portion 3029 to avoid other parts, such as the concentrator 400.

[0059] Furthermore, if Figure 2 and Figure 3 As shown, in order to prevent glare, the light-shaped baffle 301 is provided with a bending protrusion 3011 for changing the propagation path of the light emitted by the light-emitting element 600. Specifically, the bending protrusion 3011 can be formed on the side of the light-shaped baffle 301 away from the ablation bottom plate 3021 by stamping or bending, so that the light emitted by the light-emitting element 600 can be deflected or the light intensity can be weakened after passing through the concentrator 400, thereby avoiding the discomfort caused by the strong light.
