[0002] With the innovation and continuous development of vehicle technology, headlights have also evolved from the original single lighting attribute to personalized appearance, safe interaction and intelligent driving (small size, high power). The price cost of the headlight module in the headlight has also increased accordingly.

[0003] In the related art, when a headlight is simply bumped or found to be defective during inspection before leaving the factory, the headlight needs to be completely replaced, resulting in high maintenance costs for the headlights on the user's vehicle and high production costs for the headlights on the production side. Summary of the invention

[0004] The embodiments of the present application provide a vehicle lamp, a vehicle lamp module and a vehicle, in order to reduce the maintenance and use costs at the user end and the manufacturing costs at the production end.

In this embodiment, based on the detachable connection between the cover and the housing, that is, after the vehicle lamp leaves the factory, the cover can still be detached from the housing as required, and the cover can be reassembled to the housing. With such a design, when the vehicle lamp module is damaged, the cover can be opened to repair the vehicle lamp module, thereby saving the high cost of replacing the vehicle lamp module. In addition, when the headlight is assembled and tested, if the headlight module is found to be faulty, the headlight module can be repaired by opening the cover without replacing all the headlights, which can reduce production costs. Since the orthographic projection of the headlight module on the plane where the shell opening is located falls within the shell opening in the first direction, it can ensure that the headlight module as a whole can be smoothly removed from the shell opening, so that the headlight module can be easily removed from the small space cavity for easy repair, and the headlight module can be easily replaced, improving the user's subsequent maintenance capabilities for the headlight.

[0006] In some embodiments, the shell includes a plurality of surrounding walls, and in the first direction, the surrounding wall directly opposite to the headlight module and located on the backlight side of the headlight module is set as a first surrounding wall, the first surrounding wall is provided with the shell opening, and the first surrounding wall is provided with a first fixing hole on a side away from the accommodating cavity, and the headlight further includes a first fastener, and the first fastener passes through the cover body and is detachably fixedly connected to the first fixing hole to fix the cover body to the first surrounding wall.

In addition, the structure is simple and the stability is high through the coordinated fixing method of the first fastener and the first fixing hole.

[0007] In some embodiments, a first annular groove is provided on a side of the first surrounding wall away from the accommodating cavity, the shell opening is located in the area surrounded by the first annular groove, and the first fixing hole is located outside the area surrounded by the first annular groove; the vehicle lamp also includes a first sealing ring, which is provided in the first annular groove and clamped between the inner wall of the first annular groove and the cover body.

[0008] In some embodiments, the bottom wall of the first annular groove is provided with an annular protrusion, the annular protrusion protrudes from the bottom wall of the first annular groove in the direction of the cover body, and the annular protrusion surrounds the shell opening. In this embodiment, since the shell opening is located in the area surrounded by the first annular groove, the first fixing hole is located outside the area surrounded by the first annular groove; that is, the position where the first fastener passes through the cover body is located outside the area surrounded by the first annular groove, so that even if the gas passes through the through hole of the cover body for passing the first fastener, it will be blocked outside by the first sealing ring and cannot enter the accommodating cavity from between the first part of the cover body and the first surrounding wall, thereby effectively improving the airtightness between the cover body and the first surrounding wall of the shell.

[0009] In some embodiments, the cover body is provided with a cover body opening, and the vehicle lamp module includes a body, and the body is sealed and connected to the cover body to seal and cover the cover body opening.

In addition, the vehicle lamp module 10 in this embodiment may also be other types of vehicle lamp modules 10 such as a micro-matrix lamp group.

[0054] In some embodiments, the air conditioning system may cool and dissipate heat for the vehicle lamp 100 . For example, the liquid cooling plate of the air conditioning system may be used to cool and dissipate heat for the vehicle lamp module 10 of the vehicle lamp 100 , so as to improve the heat dissipation effect of the vehicle lamp 100 .

[0055] The following is an example of the vehicle lamp 100 provided in the embodiment of the present application in combination with the above application scenario.

[0056] Figure 2 A schematic structural diagram of a vehicle lamp 100 provided in an embodiment of the present application; Figure 3 for Figure 2 The simple structural diagram of the vehicle lamp 100 in the embodiment of the present application is shown in FIG. Figure 1 In the vehicle 1000, it can also be applied to Figure 1 In vehicles 1000 or other means of transportation, such as airplanes, ships, trains, robots, etc., to achieve lighting.

[0057] Reference Figure 2 and Figure 3 The headlight 100 includes a headlight housing 50 and a headlight module 10 located in the headlight housing 50. The headlight module 10 is used to realize the lighting and interactive functions of the headlight 100. The interactive functions of the headlight module 10 include but are not limited to identifying complex road conditions, projecting text or image information on the road, etc.

[0058] Figure 4The structure of a vehicle light module 10 provided in the embodiment of the present application is schematically shown. The vehicle light module 10 in the embodiment of the present application can be a DLP light group, a micro-matrix light group, an ISC (Interactive Signal Communication) light group, a SIDP (Surrounding Interactive Dynamic Projection) light group, or other light groups. The vehicle light module 10 in the embodiment of the present application can be applied not only to Figure 2 The vehicle lamp 100 in the embodiment may also be applied to lighting systems in other vehicles.

[0059] Reference Figure 4 The vehicle lamp module 10 includes a body 20 and an optical assembly 30. The body 20 is used to connect with the housing 60 of the vehicle lamp 100 to connect the vehicle lamp module 10 to the housing 60 of the vehicle lamp 100. The optical assembly 30 is used to realize the lighting and interactive functions of the vehicle lamp module 10, wherein the interactive functions are as follows: Figure 2 The interactive functions in the embodiment will not be described in detail here.

[0060] The body 20 includes a shell 21 and a fixing portion 22 on the shell 21 . The shell 21 surrounds a receiving cavity 211 . The optical component 30 is disposed in the receiving cavity 211 . The fixing portion 22 is used to fix the shell 21 to the housing 60 of the vehicle lamp 100 .

[0061] It is understandable that the housing 21 and the fixing portion 22 of the body 20 may be integrally formed, or may be connected together later, such as by welding, assembly fixing connection (bolts, screws, etc.) or bonding, etc. The shape of the housing 21 is not specifically limited, and is specifically designed according to a specific installation scenario.

[0062] The optical assembly 30 includes a light source 31 , a lens 32 , a reflector (not shown in the figure), and a processing chip (not shown in the figure).

[0063] The light source 31 can be a light source 31 such as UHP, LED, LASER, etc., and of course, can also be other lighting light sources 31. The light source 31 is disposed in the receiving cavity 211 to emit light.

[0064] The reflector is disposed in the receiving cavity 211 and is used for reflecting the light emitted by the light source 31 so as to be emitted from the lens 32 .

[0065] The number of lenses 32 can be multiple or one. Specifically, the lens 32 is connected to one end of the housing 21. The light emitted by the light source 31 is emitted to the outside of the housing 21 through the lens 32. For the convenience of description, the direction in which the light emitted by the light source 31 is emitted through the lens 32 is set as the light emitting direction, and the position where the light emitted by the light source 31 is emitted is the light emitting side of the lamp module 10. Specifically, the side of the housing 21 where the lens 32 is installed is the light emitting side of the lamp module 10. The direction opposite to the light emitting direction is the backlight direction, and the side opposite to the light emitting side of the lamp module 10 in the first direction X is the backlight side of the lamp module 10. In some embodiments, the first direction X is also the length direction of the lamp module 10 (the length of the lamp module 10 is greater than the width and height of the lamp module 10).

[0066] The processing chip may include a control board and a DMD chip, the light source 31 is refracted on the DMD chip, and the DMD chip emits light onto the projection screen after receiving a control signal from the control board. It is understandable that the processing chip may also include some other functional chips.

[0067] Figure 5 for Figure 2 A schematic structural diagram of a lamp housing 50 of a vehicle lamp 100 in the embodiment; Figure 6 for Figure 5 A partial enlarged schematic diagram of point A in the middle.

[0068] Reference Figure 5 and Figure 6 In some embodiments, the lamp housing 50 includes a shell 60 and a cover 70 .

[0069] In some embodiments, the shell 60 includes a main body 61 and a light-transmitting portion 62. The light-transmitting portion 62 is the front cover of the lamp housing 50 for emitting light. The light-transmitting portion 62 is sealed and bonded to the main body 61 and encloses with the main body 61 to form a receiving cavity 601 having a shell opening 602. Part or all of the headlight module 10 is located in the receiving cavity 601. For example, the lens 32 of the headlight module 10 is located in the receiving cavity 601. For another example, part of the outer shell 21 of the headlight module 10 is located in the receiving cavity 601, and part of it without the outer shell 21 is located outside the receiving cavity 601. For another example, the entire headlight module 10 is located in the receiving cavity 601.

[0070] After the light-transmitting portion 62 is forcibly removed from the main body 61, the connection surface between the main body 61 and the light-transmitting portion 62 will be affected. When the light-transmitting portion 62 is re-bonded, the sealing performance of the connection between the main body 61 and the light-transmitting portion 62 cannot be guaranteed to meet the standard. Therefore, the light-transmitting portion 62 and the main body 61 in this embodiment cannot be disassembled after leaving the factory.

[0071] In some other implementations, the main body 61 and the light-transmitting portion 62 may also be integrally formed to improve the sealing performance of the connection position between the main body 61 and the light-transmitting portion 62 .

[0072] It is understandable that the shapes of the shell 60 and the light-transmitting portion 62 are not specifically limited in this application and may be regular or irregular. The shape of the shell 60 in the accompanying drawings is for reference only and is not a limited shape of the shell 60 in this embodiment.

[0073] In some embodiments, the cover 70 is sealed and connected to the housing 60, and seals the housing opening 602. It should be noted that in this embodiment, the housing opening 602 is sealed and covered by the cover 70, which not only includes a scheme in which the housing opening 602 is completely sealed and covered by the cover 70 itself, but also includes a scheme in which the housing opening 602 is sealed and covered by the cover 70 and other components. For example, in some specific embodiments, the cover 70 also has an opening, and the opening on the cover 70 is sealed by other components, such as the opening on the cover 70 is sealed by the outer shell 21 of the lamp module 10. In this embodiment, the airtightness of the accommodating cavity 601 can be ensured by the cooperation between the cover 70 and the housing 60, and the working environment of the lamp module 10 in the accommodating cavity 601 can be effectively improved, and the service life and light output efficiency can be improved.

[0074] The cover 70 is detachably connected to the housing 60, that is, after the lamp 100 leaves the factory, the cover 70 can still be detached from the housing 60 as required, and the cover 70 can be reassembled to the housing 60, and the sealing performance between the cover 70 and the housing 60 can be ensured. With such a design, when the lamp module 10 is damaged, the cover 70 can be opened to repair the lamp module 10, thereby saving the high cost of replacing the lamp module 10. In addition, when the lamp 100 is assembled and tested, if it is found that the lamp module 10 is faulty, the lamp housing 50 does not need to be scrapped (the main body 61 and the light-transmitting part 62 are disassembled), and the lamp module 10 can be repaired by opening the cover 70. It can be understood that the repair in this embodiment includes repairing the lamp module 10 in the accommodating cavity 601, and also includes repairing the lamp module 10 after it is taken out of the housing opening 602 in some cases.

[0075] In this embodiment, the method of taking out the vehicle lamp module 10 from the housing opening 602 includes first splitting the vehicle lamp module 10 into multiple pieces and taking them out in the accommodating cavity 601, and also includes directly taking out the vehicle lamp module 10 as a whole from the housing opening 602. It is understandable that if the vehicle lamp module 10 is to be taken out as a whole from the housing opening 602, the diameter of the housing opening 602 should be large enough to facilitate the vehicle lamp module 10 to pass through the housing opening 602 as a whole.

[0076] In some embodiments, the housing opening 602 is located at the backlight side of the vehicle lamp module 10, and in the first direction X, the orthographic projection of the vehicle lamp module 10 on the plane where the housing opening 602 is located falls within the range of the housing opening 602. In this embodiment, since in the first direction X, the orthographic projection of the vehicle lamp module 10 on the plane where the housing opening 602 is located falls within the range of the housing opening 602, it can be ensured that the vehicle lamp module 10 as a whole can be smoothly removed from the housing opening 602, so that the vehicle lamp module 10 can be conveniently removed from the accommodating cavity 601 with a smaller space for easy maintenance, and the vehicle lamp module 10 can also be conveniently replaced, thereby improving the subsequent maintenance and repair capabilities of the user end for the vehicle lamp 100.

[0077] Since the housing opening 602 is located on the backlight side of the vehicle lamp module 10, and usually, the length direction of the vehicle lamp module 10 is substantially consistent with the first direction X, and the length of the vehicle lamp module 10 is usually greater than the height and width, the caliber of the housing opening 602 can be effectively reduced, thereby improving the structural strength of the housing 60. In addition, since the housing opening 602 is located on the backlight side of the vehicle lamp module 10, and the fasteners fixing the vehicle lamp module 10 are mostly along the first direction X, it is also convenient to remove and install the fasteners.

[0078] Reference Figure 5 and Figure 6 In some embodiments, the cover body 70 is provided with a cover body opening 701, a part of the cover body 70 is used to be sealed and connected with the shell body 60, and another part of the cover body 70 is sealed and connected with the vehicle light module 10, and the cover body opening 701 is sealed and covered by the vehicle light module 10, and the shell opening 602 is sealed and covered by the cover body 70 and the vehicle light module 10. In this embodiment, the shell opening 602 can be sealed and covered by the cover body 70 and the vehicle light module 10 to ensure the airtightness requirement of the accommodating cavity 601. In addition, a part of the vehicle light module 10 can be connected to the outside of the accommodating cavity 601 through the cover body opening 701, so that the vehicle light module 10 can dissipate a large amount of heat through the part exposed outside the accommodating cavity 601, so as to improve the heat dissipation efficiency of the vehicle light module 10.

[0079] In some embodiments, the cover body 70 includes a first part 71 connected to the shell 60, a second part 72 connected to the body 20, and a connecting portion 73 connected between the first part 71 and the second part 72, and the cover body opening 701 is opened in the middle of the second part 72, wherein the first part 71 and the connecting portion 73 are sealed, and the second part 72 and the connecting portion 73 are also sealed.

[0080] In some embodiments, the first portion 71, the connecting portion 73, and the second portion 72 are all annular, the first portion 71 surrounds the connecting portion 73, the connecting portion 73 surrounds the second portion 72, and the second portion 72 surrounds to form the cover opening 701. It is understandable that the first portion 71, the connecting portion 73, and the second portion 72 can all be circular, rectangular, triangular, or other annular structures.

[0081] Reference Figure 5 and Figure 6 In some embodiments, the housing 60 includes a plurality of surrounding walls 80. Specifically, the plurality of surrounding walls 80 constitute the aforementioned main body portion 61 and the light-transmitting portion 62. In the first direction X, the surrounding wall 80 directly facing the vehicle lamp module 10 and located on the backlight side of the vehicle lamp module 10 is set as a first surrounding wall 81, and the first surrounding wall 81 is provided with a housing opening 602. It should be noted that the shape of the first surrounding wall 81 is not specifically limited. The first surrounding wall 81 is generally plate-shaped, for example, it can be a plane, it can also be a curved surface, and it can also be a combination of a plane and a curved surface. In addition, the number of first surrounding walls 81 forming the housing opening 602 is also not limited, and it can be one first surrounding wall 81 or multiple first surrounding walls 81.

[0082] A first fixing hole 811 is provided on one side of the first surrounding wall 81 away from the accommodating cavity 601 . The vehicle lamp 100 further includes a first fastener 92 . The first fastener 92 passes through the cover body 70 and is detachably fixedly connected to the first fixing hole 811 to fix the cover body 70 to the first surrounding wall 81 .

[0083] Specifically, the first portion 71 is attached to a side of the first surrounding wall 81 away from the accommodating cavity 601 , and the first fastener 92 passes through the first portion 71 of the cover body 70 and is detachably fixedly connected to the first fixing hole 811 to fix the first portion 71 to the first surrounding wall 81 .

[0084] Specifically, a first assembly hole 711 corresponding to the position of the first fixing hole 811 is formed on the first portion 71 , and the first fastener 92 passes through the first assembly hole 711 and is fixedly connected to the first fixing hole 811 .

[0085] In some implementations, the first fixing hole 811 is a threaded hole, and the first fastener 92 is a bolt or a screw.

[0086] In some other implementations, the first fixing hole 811 may also be a pin hole, and the first fastener 92 may be a pin, and the first portion 71 may be fixed to the first surrounding wall 81 by inserting the pin into the pin hole.

[0087] In this embodiment, since the first fastener 92 passes through the cover body 70 and is fixed together with the first fixing hole 811 to fix the cover body 70 to the first surrounding wall 81 of the shell 60, the first fastener 92 can be controlled from the outside of the accommodating cavity 601 to facilitate the disassembly or assembly of the first fastener 92 from the outside of the accommodating cavity 601, so as to facilitate the separation of the cover body 70 from the first surrounding wall 81.

[0088] It is understandable that in some other embodiments, the cover 70 may be detachably connected to the housing 60 by other means such as snap connection, magnetic connection, etc.

[0089] Since the first fastener 92 passes through the cover body 70 and is fixed to the first fixing hole 811, the first assembly hole 711 of the cover body 70 for installing the first fastener 92 is prone to water and air leakage, resulting in that the airtightness of the accommodating cavity 601 cannot meet the requirements. Figure 5 and Figure 6 In some embodiments, a first annular groove 812 is provided on a side of the first surrounding wall 81 away from the accommodating cavity 601, the shell opening 602 is located in the area surrounded by the first annular groove 812, and the first fixing hole 811 is located outside the area surrounded by the first annular groove 812; the vehicle lamp 100 also includes a first sealing ring 93, the first sealing ring 93 is provided in the first annular groove 812, and the first sealing ring 93 is clamped between the inner wall of the first annular groove 812 and the cover body 70, specifically, the first sealing ring 93 is clamped by the first part 71 and the inner wall of the first annular groove 812 to ensure the sealing performance. In this embodiment, since the shell opening 602 is located in the area surrounded by the first annular groove 812, the first fixing hole 811 is located outside the area surrounded by the first annular groove 812; that is, the position where the first fastener 92 passes through the cover body 70 is located outside the area surrounded by the first annular groove 812, so that even if the gas passes through the through hole (first assembly hole 711) of the cover body 70 for passing through the first fastener 92, it will be blocked outside by the first sealing ring 93 and cannot enter the accommodating cavity 601 from between the first part 71 of the cover body 70 and the first surrounding wall 81, thereby effectively improving the airtightness between the cover body 70 and the first surrounding wall 81 of the shell 60.

[0090] In order to further improve the sealing performance between the first portion 71 of the cover body 70 and the first surrounding wall 81, in some embodiments, the bottom wall of the first annular groove 812 is provided with an annular protrusion 91, the annular protrusion 91 protrudes from the bottom wall of the first annular groove 812 toward the cover body 70, and the annular protrusion 91 surrounds the housing opening 602. In this embodiment, since the inner wall of the first annular groove 812 is provided with an annular protrusion 91, and the annular protrusion 91 protrudes from the bottom wall of the first annular groove 812 toward the cover body 70, the contact area with the first sealing ring 93 can be increased, and the contact surface between the annular protrusion 91 and the first sealing ring 93 is a continuously curved surface, so that the sealing performance between the first surrounding wall 81 and the first sealing ring 93 can be improved. Moreover, the airtightness requirement between the cover body 70 and the first surrounding wall 81 can be met without the cover body 70 applying too much pressure to the first surrounding wall 81. When the headlight module 10 uses a processing chip such as a DMD chip whose performance will be affected by too much pressure, the airtightness requirement between the cover body 70 and the first surrounding wall 81 can be met without the cover body 70 applying too much pressure to the first surrounding wall 81. Therefore, under the premise of ensuring the airtightness between the cover body 70 and the first surrounding wall 81, it can be ensured that the DMD chip will not be subjected to too much pressure, thereby not affecting the performance of the DMD chip.

[0091] In some embodiments, a circular protrusion 91 is also provided at a position corresponding to the first circular groove 812 on one side of the first part 71 of the cover body 70 facing the first surrounding wall 81, and the circular protrusion 91 protrudes toward the first surrounding wall 81 from the side of the first part 71 facing the first surrounding wall 81, so that the airtightness between the first sealing ring 93 and the first part 71 of the cover body 70 can be ensured, so as to further reduce the pressure applied by the first part 71 of the cover body 70 to the first surrounding wall 81, thereby reducing the impact on the performance of the DMD chip.

[0092] It is understandable that the number of the first sealing rings 93 and the number of the first annular grooves 812 may be one or more, and the embodiment of the present application does not specifically limit the number of the first sealing rings 93 and the number of the first annular grooves 812.

[0093] Figure 7 for Figure 3 An exploded schematic diagram of a vehicle lamp 100 in the embodiment; Figure 8 for Figure 7 A local enlarged schematic diagram of point B in the middle.

[0094] Reference Figure 7 and Figure 8In some embodiments, the lamp module 10 is sealed and connected to the second portion 72 of the cover 70 through the fixing portion 22, and the cover opening 701 is sealed and covered by the lamp module 10, wherein the fixing portion 22 and the second portion 72 of the cover 70 are detachably connected. In this embodiment, since the fixing portion 22 and the second portion 72 of the cover 70 are detachably connected, the cover 70 can be easily separated from the lamp module 10. When the first portion 71 is separated from the first surrounding wall 81 of the housing 60, the cover 70 can be easily separated from the housing 60 and the lamp module 10, and then the housing opening 602 can be opened, so that the lamp module 10 can be taken out from the housing opening 602 to replace or repair the lamp module 10. In addition, since the second portion 72 is provided with the cover opening 701, part of the lamp module 10 must be exposed outside the accommodating cavity 601 through the cover opening 701, so as to improve the heat dissipation efficiency of the lamp module 10.

[0095] Specifically, the cover opening 701 on the second portion 72 is sealed by the body 20 of the vehicle lamp module 10 .

[0096] Reference Figure 2 and Figure 3 The housing 21 includes an end cap 212 facing the backlight side of the lamp module 10 and a side wall 213 disposed on the end cap 212. The side wall 213 is connected to the periphery of the end cap 212 and encloses the end cap 212 to form a receiving cavity 211. The fixing portion 22 is sealed to the periphery of the end cap 212. The end cap 212 is used to cover the cover opening 701 on the second part 72. The fixing portion 22 is arranged around the end cap 212, and an opening is provided on the end cap 212, so that the fixing portion 22 is sealed and connected to the second part 72, that is, the cover opening 701 can be sealed and covered by the fixing portion 22 and the end cap 212 to ensure the airtightness of the receiving cavity 601.

[0097] In some embodiments, the fixing portion 22 and the end cap 212 are integrally formed, which can reduce the difficulty of processing and improve the sealing of the connection between the end cap 212 and the fixing portion 22. In addition, the connection strength between the end cap 212 and the fixing portion 22 can be improved to improve the fixing stability of the lamp module 10.

[0098] Reference Figure 7 and Figure 8In some embodiments, a fixing hole is provided on the body 20. For the sake of distinction, the fixing hole of the body 20 is set as a second fixing hole 221. Specifically, the second fixing hole 221 is formed on the fixing portion 22. A second assembly hole 721 is provided on the portion of the second part 72 corresponding to the second fixing hole 221. The lamp 100 further includes a second fastener 94. The second fastener 94 passes through the second assembly hole 721 and is detachably connected to the second fixing hole 221. In this embodiment, the second fastener 94 passes through the second assembly hole 721 and is detachably connected to the second fixing hole 221, so that the second part 72 can be fixed to the fixing portion 22, and the fixing portion 22 can be separated from the second part 72, so as to realize the assembly and disassembly between the second part 72 and the fixing portion 22, so as to realize the assembly and disassembly between the lamp module 10 and the cover 70, and to facilitate the maintenance and replacement of the lamp module 10.

[0099] Specifically, the second portion 72 is attached to a side of the fixing portion 22 away from the receiving cavity 211, and the fixing portion 22 is located on the outer side of the side wall 213 perpendicular to the first direction X, so that when the fixing portion 22 and the second portion 72 are fixed, the normal layout of the optical component 30 in the receiving cavity 211 will not be affected.

[0100] In some implementations, the second fixing hole 221 is a threaded hole, and the second fastener 94 is a bolt or a screw.

[0101] In some other implementations, the second fixing hole 221 may also be a pin hole, and the second fastener 94 may be a pin, and the second portion 72 may be fixed to the fixing portion 22 by inserting the pin into the pin hole.

[0102] It is understandable that in some other embodiments, the second portion 72 may be detachably connected to the fixing portion 22 by other means such as snap connection, magnetic connection, etc.

[0103] In order to ensure that the cover opening 701 on the second part 72 can be sealed, in some embodiments, an annular groove is provided on the body 20. For the sake of distinction, the annular groove on the body 20 is set as the second annular groove 222. Specifically, the second annular groove 222 is provided on the fixing portion 22, the cover opening 701 is located in the area surrounded by the second annular groove 222, the second fixing hole 221 is located in the area surrounded by the second annular groove 222, and is located outside the cover opening 701. The lamp 100 also includes a second sealing ring 95, which is provided in the second annular groove 222. The second fastener 94 passes through the cover 70 and is detachably fixedly connected to the second fixing hole 221 to fix the second part 72 of the cover 70 to the fixing portion 22 of the body 20, and clamp the second sealing ring 95 between the cover 70 and the inner wall of the second annular groove 222. Specifically, the second sealing ring 95 is clamped by the second part 72 and the inner wall of the second annular groove 222 to ensure sealing performance. In the present embodiment, since the cover opening 701 is located in the area surrounded by the second annular groove 222, the second fixing hole 221 is located inside the area surrounded by the second annular groove 222; that is, the position where the second fastener 94 passes through the second portion 72 is located inside the area surrounded by the second annular groove 222, so that even if the gas passes through the through hole (second assembly hole 721) of the second portion 72 for passing through the second fastener 94, it will be blocked outside by the second sealing ring 95 and cannot enter the accommodating cavity 601 from between the second portion 72 of the cover body 70 and the fixing portion 22, thereby effectively improving the airtightness between the fixing portion 22 and the second portion 72 of the cover body 70.

[0104] In order to further improve the sealing performance between the second portion 72 of the cover body 70 and the fixing portion 22, in some embodiments, the bottom wall of the second annular groove 222 is provided with an annular protrusion 91, the annular protrusion 91 protrudes from the bottom wall of the second annular groove 222 in the direction of the second portion 72, and the annular protrusion 91 surrounds the cover body opening 701. In this embodiment, since the inner wall of the second annular groove 222 is provided with an annular protrusion 91, and the annular protrusion 91 protrudes from the bottom wall of the second annular groove 222 in the direction of the second portion 72 of the cover body 70, the contact area with the second sealing ring 95 can be increased, and the contact surface between the annular protrusion 91 and the second sealing ring 95 is a continuously curved surface, so that the sealing performance between the fixing portion 22 and the first sealing ring 93 can be improved. Moreover, the airtightness requirement between the fixing part 22 and the second part 72 can be met without the second part 72 applying too much pressure to the fixing part 22. When the headlight module 10 uses a processing chip such as a DMD chip whose performance will be affected by too much pressure, the airtightness requirement between the fixing part 22 and the second part 72 can be met without the second part 72 applying too much pressure to the fixing part 22. Therefore, under the premise of ensuring the airtightness between the fixing part 22 and the second part 72, it can be ensured that the DMD chip will not be subjected to too much pressure, thereby not affecting the performance of the DMD chip.

[0105] In some embodiments, a ring-shaped protrusion 91 is also provided at a position corresponding to the second ring-shaped groove 222 on a side of the second part 72 of the cover body 70 facing the fixing part 22, and the ring-shaped protrusion 91 protrudes toward the fixing part 22 from the side of the second part 72 facing the fixing part 22, so that the airtightness between the second sealing ring 95 and the second part 72 can be ensured, so as to further reduce the pressure applied by the second part 72 to the fixing part 22, thereby reducing the impact on the performance of the DMD chip.

[0106] It is understandable that the number of the second sealing rings 95 and the number of the second annular grooves 222 may be one or more, and the embodiment of the present application does not specifically limit the number of the second sealing rings 95 and the number of the second annular grooves 222.

[0107] Since the greater the power of the vehicle lamp module 10, the higher the heat dissipation requirement is, in order to improve the heat dissipation efficiency of the vehicle lamp module 10 in the embodiment of the present application, refer to Figure 3-Figure 8In some embodiments, the vehicle lamp module 10 further includes a radiator 41, and the radiator 41 at least partially extends out of the accommodating cavity 601 from the cover opening 701. First, since the vehicle lamp module 10 is provided with the radiator 41 in this embodiment, the heat dissipation capacity of the vehicle lamp module 10 can be improved by the radiator 41. In addition, since the radiator 41 of the vehicle lamp module 10 can partially extend out of the accommodating cavity 601 from the cover opening 701, the radiator 41 can conduct a large amount of heat from the part outside the cover opening 701 to the outside of the accommodating cavity 601, and effectively dissipate the heat, thereby effectively improving the heat dissipation performance of the vehicle lamp module 10. Moreover, since part of the radiator 41 of the vehicle lamp module 10 is located outside the accommodating cavity 601, the length of the radiator 41 in the first direction X can be appropriately increased without being limited by the space of the accommodating cavity 601. By increasing the length of the radiator 41 in the first direction X, the heat exchange area of ​​the radiator 41 can be increased, thereby effectively improving the heat dissipation effect of the radiator 41 on the vehicle lamp module 10.

[0108] In some embodiments, the heat sink 41 is disposed on the housing 21 of the lamp module 10. Specifically, the heat sink 41 is disposed on the side of the housing 21 away from the light emitting side, that is, on the side of the housing 21 facing the backlight side, and is located in the area surrounded by the second annular groove 222. Since the heat sink 41 is located in the area surrounded by the second annular groove 222, the heat sink 41 will not affect the normal layout of the second sealing ring 95 in the second annular groove 222, and will not affect the sealing performance of the accommodating cavity 601.

[0109] Specifically, the heat sink 41 is disposed on a side of the end cover 212 away from the container, so that a portion of the heat sink 41 can extend from the cover opening 701 out of the receiving cavity 601 to improve heat dissipation performance. It is understood that in some other embodiments, the heat sink 41 may not extend out of the receiving cavity 601.

[0110] In some embodiments, the length of the heat sink 41 in the first direction X is 0.3-2 times the length of the housing 21 in the first direction X. Within this range, the heat sink 41 can meet the heat dissipation requirements of the lamp module 10 and improve the heat dissipation performance.

[0111] In some embodiments, the headlight module 10 further includes a fan 42 , which is connected to a side of the radiator 41 away from the housing 21 . The fan 42 can improve the heat exchange efficiency of the radiator 41 and quickly dissipate the heat on the radiator 41 to further improve the heat dissipation efficiency of the headlight module 10 .

[0112] In some embodiments, the fan 42 extends out of the accommodating cavity 601 through the cover opening 701, so that it will not be restricted by the space of the accommodating cavity 601. The space outside the accommodating cavity 601 can be effectively utilized. Without increasing the volume of the accommodating cavity 601, the fan 42 can greatly improve the cooling effect of the lamp module 10.

[0113] Compared with using the air conditioning system of the vehicle 1000 for heat dissipation, a longer pipeline needs to be arranged to connect the liquid cooling plate of the air conditioning system, which increases the overall layout difficulty of the air conditioning system. In this embodiment, the lamp module 10 dissipates heat through the fan 42, which can be independent of the air conditioning system, can reduce the overall layout difficulty, reduce the manufacturing cost, and can also meet the heat dissipation requirements.

[0114] Reference Figure 3 and Figure 7 In some embodiments, the vehicle lamp 100 further includes a bracket 96 , which is connected to the housing 60 and is located in the accommodating cavity 601 , and the vehicle lamp module 10 is fixed to the bracket 96 .

[0115] Specifically, the fixing portion 22 is attached to the bracket 96, and the fixing portion 22 is located on the side of the bracket 96 facing the cover 70. The fixing portion 22 is provided with a third fixing hole 223. The vehicle lamp 100 further includes a third fastener 97, and the third fastener 97 passes through the third fixing hole 223 and is fixedly connected to the bracket 96 to fix the vehicle lamp module 10 to the bracket 96. Since the third fastener 97 passes through the third fixing hole 223 to fix the fixing portion 22 to the bracket 96, and the fixing portion 22 is located on the side of the bracket 96 facing the cover 70, the direction in which the third fastener 97 penetrates into the third fixing hole 223 is from the backlight side to the light emitting side, and the cover 70 and the housing opening 602 are located on the backlight side of the vehicle lamp module 10, so that the cover 70 is detached from the housing 60, and the third fastener 97 can be conveniently operated through the housing opening 602, and the third fastener 97 is conveniently detached or assembled to improve operability.

[0116] In some embodiments, the third fixing hole 223 is disposed opposite to the housing opening 602 in the first direction X, so that the third fastener 97 can be more conveniently disassembled or assembled through the housing opening 602 .

[0117] Specifically, a third assembly hole 961 is provided on the bracket 96 at a position corresponding to the third fixing hole 223 , and the third fastener 97 passes through the third fixing hole 223 and is detachably fixedly connected to the third assembly hole 961 .

[0118] In some implementations, the third assembly hole 961 is a threaded hole, and the third fastener 97 is a bolt or a screw.

[0119] In some other implementations, the third assembly hole 961 may also be a pin hole, and the third fastener 97 may be a pin, and the fixing portion 22 of the lamp module 10 is fixed to the bracket 96 by inserting the pin into the pin hole.

[0120] It is understandable that in some other embodiments, the fixing portion 22 of the vehicle lamp module 10 may be fixed to the bracket 96 by other means such as snap connection, magnetic connection, etc.

[0121] In some embodiments, the third fixing hole 223 is located outside the area surrounded by the connection position of the body 20 and the cover body 70. Specifically, the third fixing hole 223 is located outside the area surrounded by the second annular groove 222, thereby preventing gas from entering the accommodating cavity 601 from the third fixing hole 223, thereby improving the sealing performance of the accommodating cavity 601 of the lamp 100.

[0122] Reference Figure 3 and Figure 7 In some embodiments, the headlight 100 further includes a driving assembly 98, which is connected to the housing 60 and is used to drive the bracket 96 to move relative to the housing 60. In this embodiment, the driving assembly 98 drives the bracket 96 to move relative to the housing 60, so that the position of the headlight module 10 relative to the housing 60 can be adjusted, so that the output light of the headlight module 10 can be adjusted or adjusted in real time, and then the output light of the vehicle 1000 can be adjusted to achieve better lighting and display effects.

[0123] In some embodiments, the drive assembly 98 can drive the bracket 96 to move in the first direction X. In some other embodiments, the drive assembly 98 can also start the bracket 96 to move in a direction perpendicular to the first direction X, or can drive the bracket 96 to move along the first direction X, or can drive the bracket 96 to move in a direction perpendicular to the first direction X.

[0124] In some embodiments, the drive assembly 98 includes a screw 981 and a drive motor (not shown) for driving the screw 981 to rotate. One end of the screw 981 is rotatably fixed to the housing 60, such as being rotatably fixed to the housing 60 through a bearing. The other end of the screw 981 is threadedly connected to the bracket 96, and the drive motor is connected to the screw 981 to drive the screw 981 to rotate. The rotation of the screw 981 can drive the bracket 96 to move along the axial direction of the screw 981.

[0125] In some embodiments, the axial direction of the screw rod 981 is consistent with the first direction X. Thus, the bracket 96 can be driven to move along the first direction X by the driving motor and the screw rod 981 .

[0126] It is understandable that the drive assembly 98 may also be other mechanical structures.

[0127] In order to be able to adjust the output light of the lamp module 10 and ensure the sealing performance and heat dissipation performance of the accommodating cavity 601 of the lamp 100, in some embodiments, a cover opening 701 is opened on the second part 72, and the body 20 of the lamp module 10 is sealed to the second part 72 to seal the cover opening 701, and the connecting part 73 is made of a flexible material so as to be able to produce deformation. In the present embodiment, since the body 20 of the light module 10 is sealed and connected to the second part 72, and the cover opening 701 is sealed and covered, it is possible to ensure that part of the body 20 of the light module 10 is exposed to the outside of the accommodating cavity 601 through the cover opening 701, such as exposing part of the radiator 41 and / or the fan 42 to the outside of the accommodating cavity 601, thereby effectively improving the heat dissipation performance of the light module 10. Moreover, since the first part 71 is sealed and connected to the shell 60, the second part 72 and the fixing part 22 of the body 20 of the light module 10 are sealed and connected, thereby ensuring that the shell opening 602 is sealed and covered through the cover 70 and the body 20 of the light module 10, thereby ensuring the sealing performance of the accommodating cavity 601. In addition, the bracket 96 can be driven to move by the driving assembly 98, and the movement of the bracket 96 drives the flexible material connecting portion 73 to extend and move, so that the cover 70 will not limit the movement of the bracket 96, so as to adjust the position of the bracket 96, and ensure the adjustment of the output light of the headlight module 10 of the headlight 100 in this embodiment. In addition, since the first part 71 and the shell 60 are detachably connected, and the second part 72 and the fixing part 22 of the body 20 are detachably connected, it is also convenient to replace and repair the headlight module 10.

[0128] In some embodiments, the connecting portion 73 is made of rubber or other metal or non-metal flexible materials. It should be noted that the flexible material of the connecting portion 73 has a certain ductility, so as to prevent the connecting portion 73 from breaking or disconnecting when being stretched, so as to ensure the sealing of the accommodating cavity 601.
