Description

Technical Field

[0001] The present application relates to the technical field of vehicle lamps, and in particular to a vehicle lamp module and a vehicle. Background Art

[0002] Pixel headlights are a type of headlight that can project image-like effects. Depending on the road conditions and vehicle speed, pixel lights can adjust the light brightness and control the light imaging effects. They will not overly stimulate the human eye and avoid dazzling conditions, thereby improving the driver's visibility and ensuring driving safety.

[0003] In the related art, pixel car lights adjust the light brightness through a lens group to control the light imaging effect, but the external natural light passing through the lens group is easy to burn the lamp beads of the pixel car lights. Utility Model Content

[0004] The embodiments of the present application provide a vehicle lamp module and a vehicle, which can reduce the light entering from the lens assembly into the light source assembly and prevent the external natural light from burning the light-emitting component.

[0005] The vehicle includes a light source assembly, a lens assembly and a blocking piece, wherein the light source assembly includes a circuit board and a light-emitting component arranged on one side of the circuit board; the lens assembly is located on the side of the circuit board where the light-emitting component is arranged, and is connected to the light source assembly, and the lens assembly is used to receive and radiate the light emitted by the light-emitting component; the blocking piece is located between the circuit board and the lens assembly, and is connected to the lens assembly, and the blocking piece has a light-through hole corresponding to the light-emitting component.

[0006] Based on the headlight module of the embodiment of the present application, when the headlight module is working, the circuit board supplies power to the light-emitting component so that the light-emitting component emits light. The light emitted by the light-emitting component passes through the light-through hole on the blocking plate and enters the lens assembly. After being diverged by the lens assembly, an illumination area is formed in front of the headlight module. Since the light-emitting component generates heat when working, the blocking plate can reduce the heat transferred from the light-emitting component to the lens assembly, and can block the stray light generated by the light-emitting component from entering the lens assembly and affecting the lighting quality of the headlight module.

[0007] When the headlight module is not working, part of the external light will enter the headlight module through the lens assembly. Since the lens assembly has a divergent effect on the light emitted by the light-emitting component, the lens assembly has a focusing effect on the light entering the headlight module from the outside, causing the external natural light entering the headlight module to converge into higher-energy light. At this time, the blocking sheet can block part of the external natural light entering the headlight module from irradiating the circuit board and the light-emitting component, reducing the damage to the circuit board and the light-emitting component caused by the external natural light entering the headlight module, thereby extending the life of the headlight module.

[0008] In some embodiments of the present application, a light absorbing layer is provided on at least one side of the blocking sheet facing the lens assembly.

[0009] Based on the above embodiment, after the blocking sheet is provided with a light-absorbing layer on the side facing the lens assembly, the ability of the blocking sheet to absorb light entering from the outside into the headlight module can be improved, thereby further improving the protection of the blocking sheet to the circuit board and the light-emitting component; after the blocking sheet is provided with a light-absorbing layer on the side away from the lens assembly, the blocking sheet can absorb part of the stray light generated by the light-emitting component, thereby further improving the lighting quality of the headlight module.

[0010] In some embodiments of the present application, the light absorbing layer is a black zinc coating.

[0011] Based on the above embodiments, the black coating has good extinction ability and solar heat absorption ability, which helps the barrier sheet to eliminate stray light emitted by the light emitting element and external natural light, and absorb stray light emitted by the light emitting element and external natural light.

[0012] In some embodiments of the present application, the blocking sheet includes a main body and a connecting portion, the main body having the light-through hole; the connecting portion is connected to the main body, and the connecting portion is connected to the lens assembly.

[0013] Based on the above embodiment, the main body and the light emitting element are spaced apart in the axial direction of the lens assembly, and the blocking sheet is connected to the lens assembly via the connecting portion, which can reduce the heat transferred from the blocking sheet to the lens assembly.

[0014] In some embodiments of the present application, a portion of the edge of the main body forms a positioning edge, and the lens structure is provided with a first positioning member, and the first positioning member abuts against the positioning edge.

[0015] Based on the above embodiment, when the blocking piece is assembled with the lens assembly, the first positioning member is abutted against the positioning edge to achieve positioning of the blocking piece.

[0016] In some embodiments of the present application, the blocking sheet further includes a positioning portion, the positioning portion is connected to the main body, and the positioning portion has a positioning hole; the lens assembly is provided with a second positioning member, and the second positioning member is inserted into the positioning hole.

[0017] Based on the above embodiment, when the blocking piece and the lens assembly are assembled, the second positioning member is inserted into the positioning hole, which can guide the assembly of the blocking piece and the lens assembly and facilitate the subsequent connection between the blocking piece and the lens assembly.

[0018] In some embodiments of the present application, the main body portion extends toward the circuit board relative to the connecting portion to form a connecting groove, and the lens assembly includes a lens structure and a lens bracket. The end of the lens structure close to the circuit board is located in the connecting groove and is connected to the blocking sheet, and the lens structure is used to receive and radiate the light emitted by the light-emitting component; the lens bracket is connected to the lens structure and to the circuit board.

[0019] Based on the above embodiment, after the connecting groove is formed on the main body, one end of the lens structure is in the connecting groove, that is, at least a portion of the end of the lens structure close to the light-emitting component is wrapped by the groove wall of the connecting groove. When external natural light enters the car light module through the lens structure, the groove wall of the connecting groove can better block the external natural light and absorb the heat of the external natural light.

[0020] In some embodiments of the present application, the blocking sheet has a weight-reducing opening, the weight-reducing opening passes through the blocking sheet at the bend between the main body and the connecting portion, and the weight-reducing opening passes through the blocking sheet at the bend between the bottom wall and the side wall of the connecting groove.

[0021] Based on the above embodiments, the weight-reducing opening can reduce the weight of the blocking piece. At the same time, during the manufacturing process of the blocking piece, the sheet metal needs to be bent to form a main body, a connecting portion and a positioning portion. Since the weight-reducing opening is located at the position where the sheet metal needs to be bent, it is convenient to bend the sheet metal to form the blocking piece.

[0022] In some embodiments of the present application, the lens holder is surrounded by a receiving cavity, and the blocking sheet is located in the receiving cavity.

[0023] Based on the above embodiment, the blocking sheet is in the accommodating cavity, and the lens holder protects the blocking sheet, especially the light absorbing layer on the blocking sheet, to ensure the light extinction and heat absorption capabilities of the blocking sheet.

[0024] In a second aspect, an embodiment of the present application provides a vehicle, comprising the vehicle light module as described above.

[0025] The vehicle according to the embodiment of the present application has the above-mentioned headlight module, so the headlight module has a longer life, which can reduce the maintenance cost of the vehicle according to the embodiment of the present application.

DETAILED DESCRIPTION

[0034] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0035] Pixel headlights are a type of headlight that can project image-like effects. Depending on the road conditions and vehicle speed, pixel lights can adjust the light brightness and control the light imaging effects. They will not overly stimulate the human eye and avoid dazzling conditions, thereby improving the driver's visibility and ensuring driving safety.

[0036] In the related art, pixel car lights adjust the light brightness through a lens group to control the light imaging effect, mainly by diverging the light emitted by the lamp beads so that the pixel car lights form different lighting areas in front of the vehicle. However, on the contrary, the external natural light is focused into higher-energy light after passing through the lens group, which can easily burn the lamp beads of the pixel car lights.

[0037] To solve the above technical problems, please refer to Figures 1 to 3 As shown, the embodiment of the present application provides a vehicle light module and a vehicle, wherein the vehicle light module can reduce the light entering from the lens assembly 100 into the light source assembly 200 , thereby preventing the light emitting element 220 from being burned by external natural light.

[0038] The vehicle includes a light source assembly 200, a lens assembly 100 and a blocking sheet 600. The light source assembly 200 includes a circuit board 210 and a light emitting member 220 disposed on one side of the circuit board 210. The lens assembly 100 is located on the side of the circuit board 210 where the light emitting member 220 is disposed, and is connected to the light source assembly 200. The lens assembly 100 is used to receive and radiate light emitted by the light emitting member 220.

[0039] The blocking sheet 600 is located between the circuit board 210 and the lens assembly 100 and is connected to the lens assembly 100 . The blocking sheet 600 has a light-through hole 611 corresponding to the light-emitting element 220 .

[0040] The circuit board 210 is used to supply power to the light-emitting element 220. The circuit board 210 in the embodiment of the present application may be a PCB (Printed Circuit Board), an FPC (Flexible Printed Circuit board 210), etc. The high hardness of the PCB substrate can provide more stable support for the light-emitting element 220, and a more stable connection relationship with the lens assembly 100; the FPC substrate has good flexibility, which can buffer the impact of vehicle bumps on the light-emitting element 220.

[0041] The light emitting element 220 is used to emit light. The light emitting element 220 in the embodiment of the present application may be an LED (light-emitting diode), and the number of the light emitting elements 220 in the embodiment of the present application may be one or more. In a specific embodiment of the present application, the light emitted by one light emitting element 220 is more concentrated, which is convenient for the lens assembly 100 to diverge the light; the light emitted by multiple light emitting elements 220 is brighter. Please refer to Figure 2 As shown, the light emitting element 220 in the embodiment of the present application can be set as a rectangular structure.

[0042] The light hole 611 is used for allowing light emitted by the light emitting element 220 or external natural light to pass through. In the embodiment of the present application, the size of the light hole 611 should be set according to the size of the light emitting element 220. Please refer to Figure 1 As shown, in some embodiments of the present application, the light-through hole 611 is configured as a rectangular hole.

[0043] Based on the vehicle light module of the embodiment of the present application, when the vehicle light module is working, the circuit board 210 supplies power to the light emitting component 220 so that the light emitting component 220 emits light, and the light emitted by the light emitting component 220 passes through the light hole 611 on the blocking plate 600 and enters the lens assembly 100. After being diverged through the lens assembly 100, an illumination area is formed in front of the vehicle light module. Since the light emitting component 220 generates heat when working, at this time, the blocking plate 600 can reduce the heat transferred from the light emitting component 220 to the lens assembly 100, and can block the stray light generated by the light emitting component 220 from entering the lens assembly 100 and affecting the lighting quality of the vehicle light module.

[0044] When the headlight module is not working, part of the external light will enter the headlight module through the lens assembly 100. Since the lens assembly 100 has a divergent effect on the light emitted by the light-emitting component 220, the lens assembly 100 has a focusing effect on the light entering the headlight module from the outside, resulting in the external natural light entering the headlight module and being gathered into high-energy light. This light can release a large amount of heat. At this time, the blocking sheet 600 can reduce the part of the external natural light entering the headlight module from irradiating the circuit board 210 and the light-emitting component 220, thereby reducing the damage caused to the circuit board 210 and the light-emitting component 220 by the external natural light entering the headlight module, thereby extending the life of the headlight module.

[0045] It is understandable that the barrier sheet 600 in the embodiment of the present application can be made by physical matting and chemical matting. Physical matting is to add a matting agent to the coating so that the coating forms a film on the surface of the barrier sheet 600. The coating precipitates on the surface of the coating, making the surface of the coating uneven, increasing the scattering of light and reducing reflection. Chemical matting is to introduce some structures or groups such as polypropylene grafted substances that can absorb light into the coating to obtain low gloss.

[0046] In some embodiments of the present application, the blocking sheet 600 is provided with a light absorbing layer at least on the side facing the lens assembly 100. After the blocking sheet 600 is provided with the light absorbing layer on the side facing the lens assembly 100, the ability of the blocking sheet 600 to absorb light entering the vehicle lamp module from the outside can be improved, further improving the protection of the blocking sheet 600 to the circuit board 210 and the light emitting element 220; after the blocking sheet 600 is provided with the light absorbing layer on the side away from the lens assembly 100, the blocking sheet 600 can absorb part of the stray light generated by the light emitting element 220, further improving the lighting quality of the vehicle lamp module. In the embodiments of the present application, the outer surface of the blocking sheet 600 is provided with a light absorbing layer.

[0047] In some embodiments of the present application, the light absorbing layer is a black zinc coating, which has good extinction ability and solar heat absorption ability, and helps the blocking sheet 600 eliminate the stray light and external natural light emitted by the light emitting element 220, and absorb the stray light and external natural light emitted by the light emitting element 220. The light absorbing layer in the embodiments of the present application can also be configured as other extinction and / or light absorbing materials, such as extinction resin, etc.

[0048] Please refer to Figures 4 to 6 As shown, in some embodiments of the present application, the blocking sheet 600 includes a main body 610 and a connecting portion 620, the main body 610 has the light-through hole 611; the connecting portion 620 is connected to the main body 610, and the connecting portion 620 is connected to the lens assembly 100.

[0049] The main body 610 and the light-emitting component 220 are arranged at an axial interval in the lens assembly 100, and there is no direct contact between the two. The heat generated by the external natural light shining on the blocking sheet 600 will only be transmitted through the air, and the blocking sheet 600 is connected to the lens assembly 100 through the connecting portion 620, which can reduce the heat transferred from the blocking sheet 600 to the light-emitting assembly.

[0050] To ensure that the blocking piece 600 blocks external natural light, in some embodiments of the present application, the axial main body 610 of the lens structure 110 overlaps with the end of the lens structure 110 close to the light-emitting component 220, so that external natural light can only be irradiated onto the blocking piece 600.

[0051] Please refer to Figures 4 to 6 As shown, in some embodiments of the present application, a partial edge of the main body 610 forms a positioning edge 612, and the lens assembly 100 is provided with a first positioning member 111, and the first positioning member 111 abuts against the positioning edge 612. When the blocking sheet 600 and the lens assembly 100 are assembled, the first positioning member 111 abuts against the positioning edge 612 to position the blocking sheet 600.

[0052] In the embodiment of the present application, the first positioning member 111 can be configured as a positioning protrusion, and any side wall of the positioning protrusion abuts the positioning edge 612. The shape of the side of the positioning protrusion abutting the positioning edge 612 should correspond to the shape of the positioning edge 612. Preferably, any side wall of the positioning protrusion can be set in contact with the positioning edge 612.

[0053] Please refer to Figures 4 to 6As shown, in some embodiments of the present application, the blocking piece 600 also includes a positioning portion 630, the positioning portion 630 is connected to the main body 610, and the positioning portion 630 has a positioning hole 631; the lens assembly 100 is provided with a second positioning member 112, and the second positioning member 112 is passed through the positioning hole 631; when the blocking piece 600 and the lens assembly 100 are assembled, the second positioning member 112 is passed through the positioning hole 631, which can guide the assembly of the blocking piece 600 and the lens assembly 100 and facilitate the subsequent mutual connection of the blocking piece 600 and the lens assembly 100.

[0054] Please refer to Figure 4 As shown, in some embodiments of the present application, the second positioning member 112 is configured as a positioning column, and after the positioning column passes through the positioning hole 631, the positioning column fits against the hole wall of the positioning hole 631.

[0055] Please refer to Figure 5 as well as Figure 6 As shown, in some embodiments of the present application, the blocking sheet 600 can be configured as a centrally symmetrical structure, that is, the main body 610 is configured as a centrally symmetrical structure, the number of the positioning portions 630 is two, and the two positioning portions 630 are symmetrically arranged about the center of the main body 610, and the number of the connecting portions 620 is two, and the two connecting portions 620 are symmetrically arranged about the center of the main body 610.

[0056] Please refer to Figures 4 to 6 As shown, in some embodiments of the present application, the main body 610 is extended toward the circuit board 210 relative to the connecting portion 620 to form a connecting groove 613, and the lens assembly 100 includes a lens structure 110 and a lens bracket 120. The end of the lens structure 110 close to the circuit board 210 is located in the connecting groove 613 and is connected to the blocking sheet 600. The lens structure 110 is used to receive and radiate the light emitted by the light-emitting component 220; the lens bracket 120 is connected to the lens structure 110 and to the circuit board 210.

[0057] After the main body 610 forms a connecting groove 613, one end of the lens structure 110 is in the connecting groove 613, that is, the groove wall of the connecting groove 613 wraps at least a part of the end of the lens structure 110 close to the light-emitting component 220. When external natural light enters the car light module through the lens structure 110, the groove wall of the connecting groove 613 can better block the external natural light and absorb the heat of the external natural light.

[0058] The lens structure 110 in the embodiment of the present application includes a shell and a plurality of lenses, which are coaxially arranged and arranged in sequence in the shell; in addition, in combination with the above-mentioned lens assembly 100, a first positioning member 111 and a second positioning member 112 are provided, and the first positioning member 111 and the second positioning member 112 are both arranged on the shell.

[0059] Please refer to Figure 5 as well as Figure 6 As shown, in some embodiments of the present application, the blocking sheet 600 has a weight-reducing opening 640, and the weight-reducing opening 640 passes through the blocking sheet 600 at the bending point between the main body 610 and the connecting portion 620, and the weight-reducing opening 640 passes through the blocking sheet 600 at the bending point between the bottom wall and the side wall of the connecting groove 613.

[0060] The weight-reducing opening 640 can reduce the weight of the blocking piece 600. At the same time, during the manufacturing process of the blocking piece 600, the sheet metal needs to be bent to form the main body 610, the connecting portion 620 and the positioning portion 630. Since the weight-reducing opening 640 is located at the position where the sheet metal needs to be bent, it is convenient to bend the sheet metal to form the blocking piece 600.

[0061] In order to prevent the weight-reducing opening 640 from affecting the extinction and heat absorption capabilities of the blocking sheet 600, in some embodiments of the present application, the weight-reducing opening 640 coincides with one end of the lens structure 110 in the connecting groove 613, that is, the lens structure 110 can abut the bottom wall of the connecting groove 613 so that the end of the lens structure 110 blocks the weight-reducing opening 640, thereby preventing the light emitted by the light-emitting component 220 and external natural light from passing through the weight-reducing opening 640.

[0062] Please refer to Figure 4 As shown, in some embodiments of the present application, the lens holder 120 is surrounded by a accommodating cavity 121, and the blocking sheet 600 is located in the accommodating cavity 121. The blocking sheet 600 is protected by the lens holder 120, especially the black zinc coating on the blocking sheet 600, to ensure the extinction and heat absorption capabilities of the blocking sheet 600.
