The embodiments described below with reference to the drawings are exemplary and are intended to explain the present application, and are not to be understood as limiting the present application.

For the purpose of simplification, the components and arrangements of specific examples are described in the following. Of course, they are only examples and are not intended to limit the present application. In addition, the present application can repeatedly refer to numbers and / or letters in different examples. Such repetition is for the purpose of simplification and clarity, and does not itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0036] Below, with reference to the drawings, a vehicle lamp 1 according to the first aspect of the present application is described.

[0037] As Figure 1 , Figure 2 and Figure 6As shown, the vehicle lamp 1 comprises a lamp shell 10, a lamp cover component 20 and an optical component 30. The lamp shell 10 has a mounting cavity 12 therein. The lamp shell 10 is formed with a first mounting opening 14 and a second mounting opening 16 which respectively communicate with the mounting cavity 12. The lamp cover component 20 is arranged at the first mounting opening 14. The optical component 30 is arranged in the mounting cavity 12 and comprises a light source assembly 32, an optical element 34 and a heat dissipation assembly 36. The light source assembly 32 is fixedly connected with the optical element 34. At least one of the light source assembly 32 and the optical element 34 is fixedly connected with the heat dissipation assembly 36. The light source assembly 32 is in heat conduction cooperation with the heat dissipation assembly 36. The heat dissipation assembly 36 is arranged at the second mounting opening 16 and partially exposed outside the lamp shell 10 through the second mounting opening 16. The light emitted by the light source assembly 32 passes through the optical element 34 and then transmits through the lamp cover component 20. The first mounting opening 14 is configured to allow the optical component 30 to pass through and be fitted in the mounting cavity 12.

[0038] As can be seen, the optical component 30 comprises the light source assembly 32, the optical element 34 and the heat dissipation assembly 36. The light source assembly 32 is fixedly connected with the optical element 34. At least one of the light source assembly 32 and the optical element 34 is fixedly connected with the heat dissipation assembly 36. In this way, the structure of the optical component 30 is more stable, and the reliability of the operation of the optical component 30 is improved. The optical component 30 can be assembled in the mounting cavity 12 through the first mounting opening 14. The first mounting opening 14 provides a larger space for the assembly of the optical component 30. Therefore, the optical component 30 can be assembled as a whole in an external environment, and then the assembled optical component 30 is installed in the mounting cavity 12 as a whole, so as to improve the assembly precision of the optical component 30 in the lamp shell 10 and facilitate the modular assembly of the vehicle lamp 1. In this way, by arranging the vehicle lamp 1 to comprise the lamp shell 10, the lamp cover component 20 and the optical component 30, the assembly process can be simplified, and the production efficiency is improved. Meanwhile, the modular design is also convenient for subsequent maintenance and replacement. For example, when a certain component (such as the light source assembly 32 or the optical element 34) in the vehicle lamp 1 fails, the optical component 30 can be easily taken out from the lamp shell 10 for replacement without replacing the entire vehicle lamp 1, thereby reducing the maintenance cost. The external environment refers to a place where the optical component 30 (including the light source assembly 32, the optical element 34 and the heat dissipation assembly 36) is assembled and pre-adjusted before being installed in the mounting cavity 12 of the vehicle lamp 1 as a whole unit.

[0039] It can be understood that the light source assembly 32 can be fixedly connected with the heat dissipation assembly 36, or the optical element 34 can be fixedly connected with the heat dissipation assembly 36, or both the light source assembly 32 and the optical element 34 can be fixedly connected with the heat dissipation assembly 36, so that the optical component 30 is formed as a whole, and the stability of the operation of the optical component 30 is improved.

[0040] The lamp cover part 20 is covered on the first mounting port 14, so that the optical part 30 is in a relatively closed environment, which reduces the possibility of external impurities entering the mounting cavity 12 to affect the normal work of the optical part 30, and facilitates to improve the stability of the vehicle lamp 1.

[0041] Exemplarily, the staff first assembles the light source assembly 32, the optical element 34 and the heat dissipation assembly 36 into an integral whole in the external environment, then assembles the integral optical part 30 into the mounting cavity 12 through the first mounting port 14, and after the optical part 30 is assembled, the lamp cover part 20 is assembled on the first mounting port 14, so as to complete the assembly process of the vehicle lamp 1.

[0042] In addition, the heat dissipation assembly 36 is at least partially exposed outside the lamp shell 10 through the second mounting port 16, and the exposed heat dissipation assembly 36 can more effectively exchange heat with the external environment, helping the light source assembly 32 and other heat generating components to dissipate heat, so that the vehicle lamp 1 can still maintain stable working performance after a long time of work, facilitating to improve the service life of the vehicle lamp 1.

[0043] In some technologies, the vehicle lamp uses the following heat dissipation assembly to dissipate heat for the light source assembly: first, the heat dissipation assembly of the vehicle lamp is entirely located in the mounting cavity, and since the mounting cavity is a relatively closed environment, the heat dissipation effect of the heat dissipation assembly is poor; second, the heat dissipation assembly of the vehicle lamp is at least partially located outside the lamp shell, and the heat dissipation assembly is assembled with the light source assembly and the optical element in the mounting cavity, so that the heat dissipation assembly is not easy to form good adhesion with the light source assembly, the heat transfer efficiency is poor, or the light source assembly is first assembled with the heat dissipation assembly in the external environment to form an integral whole, and then the light source assembly and the heat dissipation assembly are assembled with the optical element in the mounting cavity, and since the assembly environment in the mounting cavity is limited, the assembly of the optical part is more difficult, and the assembly precision of the light source assembly and the optical element is also not high, which affects the working effect of the vehicle lamp.

[0044] In the embodiment of the present application, the light source assembly 32, the optical element 34 and the heat dissipation assembly 36 are first assembled into an integral whole in the external environment, and then the integral optical part 30 is mounted in the mounting cavity 12, so that the optical part 30 in the lamp shell 10 has good assembly precision, facilitating to improve the working effect of the optical part 30, and at the same time, the heat dissipation assembly 36 is at least partially exposed outside the lamp shell 10, so that the vehicle lamp 1 has good heat dissipation performance.

[0045] In some embodiments, the heat dissipation assembly 36 is a metal material such as an aluminum plate which has good heat conduction performance, so that the heat generated by the light source assembly 32 can be quickly transferred to the outside of the lamp shell 10 through the aluminum plate. Compared with using a fan or a water cooling method to dissipate heat for the light source assembly 32, the heat dissipation assembly 36 of the aluminum plate occupies less space in the lamp shell 10, and at the same time, the manufacturing cost is lower.

[0046] As Figure 6As shown, in some embodiments, the lamp housing 10 has a cylindrical portion, and the first mounting port 14 and the second mounting port 16 are respectively formed at both ends of the cylindrical portion. By distributing the first mounting port 14 and the second mounting port 16 at both ends of the cylindrical portion, the internal space of the lamp housing 10 can be utilized to the maximum extent, making the entire vehicle lamp 1 structure more compact and helping to reduce the volume and weight of the vehicle lamp 1. At the same time, the workers can assemble the optical component 30 into the mounting cavity 12 along the axial direction, so that the installation path of the optical component 30 is clearer and the assembly efficiency of the vehicle lamp 1 can be improved.

[0047] In other embodiments of this application, a first mounting port 14 is formed at one axial end of the cylindrical portion, and a second mounting port 16 is formed on the peripheral wall 18 of the cylindrical portion. In this case, the heat dissipation component 36 can be exposed outside the lamp housing 10 at least partially through the second mounting port 16 on the peripheral wall 18 of the cylindrical portion, so that the setting position of the heat dissipation component 36 is more flexible, the axial size of the optical component 30 is reduced, and it is easier to adapt to different installation environments.

[0048] like Figures 1-4 As shown, in some embodiments, the vehicle headlight 1 is configured to satisfy at least one of the following conditions A1 to A4:

[0049] In condition A1, the light source assembly 32 is fixed to the optical element 34 by the first fastener 40, and the light source assembly 32 is fixed to the heat dissipation assembly 36 by the first fastener 40. That is, the light source assembly 32, the optical element 34 and the heat dissipation assembly 36 can be fixed together by the first fastener 40, so that the structure of the optical component 30 is more stable and the number of fasteners used can be reduced.

[0050] Optionally, the first fastener 40 is configured to allow the light source assembly 32 and the optical element 34 to be detachably mounted. For example, the first fastener 40 is a threaded fastener (such as a screw), which makes the installation and removal of the light source assembly 32 and the optical element 34 more convenient, facilitates subsequent maintenance and repair, and makes the overall structure more compact and saves space.

[0051] In condition A2, the vehicle lamp 1 also includes positioning components 50. There are multiple positioning components 50, and the multiple positioning components 50 are arranged circumferentially along the second mounting port 16. Each positioning component 50 includes a positioning protrusion 52 and a positioning groove 54 for positioning and engagement. One of the positioning protrusion 52 and the positioning groove 54 is formed on the lamp housing 10, and the other is formed on the heat dissipation assembly 36. By using multiple positioning components 50 arranged circumferentially along the second mounting port 16, each positioning protrusion 52 corresponds to a positioning groove 54, so that the lamp housing 10 and the heat dissipation assembly 36 can be more accurately aligned during assembly, reducing the assembly difficulty of the optical component 30 and facilitating the improvement of the production efficiency of the vehicle lamp 1.

[0052] It can be understood that the positioning protrusion 52 can be located on the lamp shell 10, the positioning recess 54 is located on the heat dissipation assembly 36, or the positioning recess 54 can be located on the lamp shell 10, and the positioning protrusion 52 is located on the heat dissipation assembly 36, so that the setting position of the positioning part 50 is more flexible, and different installation environments can be adapted.

[0053] In condition A3, the vehicle lamp 1 further comprises a sealing member 64, one of the lamp shell 10 and the heat dissipation assembly 36 is provided with a mounting groove 60, and the other is provided with a pressing rib 62, the sealing member 64 is arranged in the mounting groove 60, and the sealing member 64 is arranged around the outer periphery of the second mounting opening 16, the sealing member 64 is sealed between the lamp shell 10 and the heat dissipation assembly 36, and the pressing rib 62 is inserted into the mounting groove 60 to extrude the sealing member 64.

[0054] As can be seen, when the heat dissipation assembly 36 and the lamp shell 10 are assembled, the pressing rib 62 can extrude the sealing member 64, so that the sealing member 64 is tightly fitted between the lamp shell 10 and the heat dissipation assembly 36, thereby improving the sealing performance of the sealing member 64. At the same time, the sealing member 64 is arranged around the outer periphery of the second mounting opening 16, which can fully cover possible water seepage or air leakage points, effectively preventing water, dust and other impurities from entering the mounting cavity 12 of the lamp shell 10, thereby affecting the normal work of the optical component 30.

[0055] In addition, the sealing member 64 is located in the mounting groove 60, so that when the heat dissipation assembly 36 and the lamp shell 10 are assembled, the sealing member 64 can still be kept on the outer periphery of the second mounting opening 16 in a pressed state, so that the working position of the sealing member 64 is more stable, and the sealing effect of the sealing member 64 is improved.

[0056] It can be understood that the mounting groove 60 can be located on the lamp shell 10, and the pressing rib 62 is located on the heat dissipation assembly 36, or the pressing rib 62 can be located on the lamp shell 10, and the mounting groove 60 is located on the heat dissipation assembly 36, so that the setting position of the sealing member 64 is more flexible.

[0057] In condition A4, the vehicle lamp 1 further comprises a second fastener 42, and the lamp shell 10 and the heat dissipation assembly 36 are fixed by the second fastener 42, that is, the optical component 30 and the lamp shell 10 can be fixed by the second fastener 42, so that the optical component 30 is more stable in the lamp shell 10, and the possibility of displacement or loosening of the optical component 30 due to vibration or external force is reduced, thereby maintaining good lighting effect.

[0058] The second fastener 42 is arranged from the outside of the lamp shell 10 to the lamp shell 10 and the heat dissipation assembly 36, so that the installation process is more intuitive and convenient. Compared with the installation mode of the second fastener arranged from the inside of the lamp shell to the lamp shell and the heat dissipation assembly from the outside to the inside, the staff is provided with more operation space, the staff can more easily pass the second fastener 42 through the lamp shell 10 and fix it to the heat dissipation assembly 36, without complicated internal operation, and at the same time, when it is necessary to maintain or replace parts, it is more convenient to disassemble the fastener from the outside of the lamp shell 10, which reduces the difficulty and cost of maintenance.

[0059] Optionally, the second fastener 42 is configured so that the lamp shell 10 and the heat dissipation assembly 36 are detachably arranged, for example, the second fastener 42 is a threaded fastener (such as a screw), and the installation and disassembly of the lamp shell 10 and the heat dissipation assembly 36 are more convenient, facilitating subsequent maintenance and overhaul, and at the same time, the overall structure is more compact, saving space.

[0060] As shown in Figure 1 , Figure 2 and Figure 5 , in some embodiments, the light source assembly 32 and the optical element 34 are respectively a plurality of, and are arranged one by one, so that the plurality of light source assemblies 32 and the plurality of optical elements 34 are arranged one by one, each light source assembly 32 is in heat conduction cooperation with the heat dissipation assembly 36, and the lamp shade component 20 is further provided with at least one light blocking structure 22, the light blocking structure 22 cooperates with the corresponding optical element 34 to block the light emitted by each of the two adjacent light source assemblies 32 from shining on the other.

[0061] It can be seen that the vehicle lamp 1 has a plurality of light source assemblies 32 and optical elements 34 arranged one by one, so that the vehicle lamp 1 can emit different light beams through different light source assemblies 32 and optical elements 34, facilitating the enrichment of the function of the vehicle lamp 1; each light source assembly 32 is in heat conduction cooperation with the heat dissipation assembly 36, so that the heat generated by each light source assembly 32 during operation can be dissipated by the heat dissipation assembly 36, facilitating the improvement of the stability of the optical component 30; the lamp shade component 20 has a light blocking structure 22, so that the light blocking structure 22 participates in the separation of the plurality of light source assemblies 32 into a plurality of independent light emitting cavities 19, so that the light source assembly 32 is not easy to affect the working effect of another light source assembly 32 when emitting light, that is, each light source assembly 32 emits light independently, and the light is shaped and focused through the corresponding optical element 34, so that the light is projected in a predetermined direction, the light blocking structure 22 effectively reduces the possibility of light cross interference between adjacent light source assemblies 32, so that the illumination area is more clear and distinct.

[0062] As shown in Figure 1 and Figure 2As shown, in some embodiments, the lampshade component 20 includes an outer lampshade 24 and an inner lampshade 26. The inner lampshade 26 covers the first mounting opening 14, and the inner lampshade 26 is provided with an optical structure corresponding to the light source component 32. The optical structure is used to uniformly display the light passing through the optical element 34 on the inner lampshade 26. The light-blocking structure 22 is provided on the inner lampshade 26, and the light-blocking structure 22 is inserted and cooperated with the optical element 34.

[0063] As can be seen, the light-blocking structure 22 participates in dividing the lamp housing 10 into multiple independent light-emitting cavities 19. For example, the light-blocking structure 22 cooperates with the optical element 34 to divide the internal space of the lamp housing 10 into multiple light-emitting cavities 19. Each light-emitting cavity 19 has a corresponding inner lamp cover 26 part with a corresponding optical structure so that the light emitted from the light source assembly 32 passes through the optical element 34 and is emitted through the corresponding optical structure. The optical structure can adjust the direction and angle of the light so that the light emitted from the light source assembly 32 and the optical element 34 can be projected along a predetermined path so as to realize that the vehicle lamp 1 emits different light.

[0064] For example, the light-blocking structure 22 divides the lamp housing 10 into upper and lower spaced light-emitting cavities 19. The inner lamp cover 26 parts corresponding to different light-emitting cavities 19 have different optical structures. The light in the upper light-emitting cavity 19 can be focused on a specific area through the corresponding optical structure, thereby improving the lighting effect and brightness, thus achieving the high beam effect of the vehicle lamp 1. The light in the lower light-emitting cavity 19 can be diffused through the corresponding optical structure, which helps to expand the lighting range and enable the light to cover the target area more widely, thereby achieving the low beam effect of the vehicle lamp 1.

[0065] The outer lamp cover 24 covers the outside of the inner lamp cover 26, which can effectively prevent dust, moisture and other impurities from the outside from contacting the inner lamp cover 26 and the light source assembly 32 area, helping to keep the inside of the vehicle lamp 1 clean. At the same time, the outer lamp cover 24 can protect the optical component 30 from being impacted by particles (such as gravel) during the vehicle 2's driving process, so that the optical component 30 can have a good working effect and reduce the maintenance cost of the vehicle lamp 1.

[0066] like Figures 1-3 As shown, in some embodiments, the heat dissipation assembly 36 includes a first heat dissipation component 360 and a second heat dissipation component 362 that are thermally connected and fixedly connected. The first heat dissipation component 360 is disposed in the mounting cavity 12 and is thermally connected to the side of the light source assembly 32 that is away from the optical element 34. The second heat dissipation component 362 is disposed at the second mounting port 16 and a portion of the second heat dissipation component 362 is exposed through the second mounting port 16 to the lamp housing 10.

[0067] It can be seen that the first heat dissipation member 360 is in thermal contact with the side of the light source assembly 32 away from the optical element 34, so that the first heat dissipation member 360 does not easily affect the light emitted by the light source assembly 32, so that the optical component 30 has good working effect, and the first heat dissipation member 360 can quickly absorb the heat generated by the light source assembly 32; the second heat dissipation member 362 is at least partially located outside the lamp housing 10, so that the heat generated by the light source assembly 32 during work can be transmitted to the second heat dissipation member 362 through the first heat dissipation member 360, and then transmitted to the outside of the lamp housing 10 by the second heat dissipation member 362, so that the light source assembly 32 can maintain a relatively low temperature during work, thereby prolonging the service life of the light source assembly 32 and improving the lighting efficiency.

[0068] As shown in Figures 1-3 some embodiments, the light source assembly 32 includes a circuit board 320 and a plurality of LED light sources, and the plurality of LED light sources are located on the side of the circuit board 320 facing the optical element 34, i.e. the plurality of LED light sources 322 and the first heat dissipation member 360 are located at both ends of the circuit board 320, so that the first heat dissipation member 360 does not easily affect the normal work of the light source assembly 32, and the first heat dissipation member 360 can transmit the heat generated by the plurality of LED light sources 322 during work to the second heat dissipation member 362, and then the second heat dissipation member 362 transmits the heat to the outside of the lamp housing 10, thereby improving the stability of the work of the light source assembly 32.

[0069] In some embodiments, the side of the light source assembly 32 that cooperates with the first heat dissipation member 360 is provided with a heat-conducting material (such as heat-conducting glue), so as to exchange heat with the first heat dissipation member 360 through the heat-conducting material, and the first heat dissipation member 360 and the second heat dissipation member 362 are also provided with a heat-conducting material, so that the heat generated by the light source assembly 32 during work can be more quickly transmitted to the outside, thereby improving the stability of the operation of the vehicle lamp 1.

[0070] As shown in Figure 1 and Figure 2 some embodiments, the light source assembly 32 and the optical element 34 are each a plurality of, and are one-to-one correspondingly arranged, each light source assembly 32 corresponds to a first heat dissipation member 360, and each light source assembly 32 is fixedly connected with the corresponding first heat dissipation member 360, and all the first heat dissipation members 360 are located on the side of the second heat dissipation member 362 away from the second mounting port 16.

[0071] It can be seen that each light source assembly 32 is fixedly connected with the corresponding optical element 34, and each light source assembly 32 is fixedly connected with the corresponding first heat dissipation member 360, so that the heat generated by each light source assembly 32 can be transmitted to the second heat dissipation member 362 by the corresponding first heat dissipation member 360, thereby improving the heat dissipation efficiency of the vehicle lamp 1, and the corresponding light source assembly 32, optical element 34 and first heat dissipation member can be assembled to form an integral whole in an external environment, thereby simplifying the assembly process of the optical component 30 and improving the assembly precision of the optical element 34.

[0072] In addition, by arranging all the first heat dissipation members 360 on the side of the second heat dissipation member 362 away from the second mounting port 16, the internal structure of the vehicle lamp 1 is more compact and orderly, thereby facilitating the miniaturization design of the vehicle lamp 1.

[0073] As shown in Figures 1-4 In some embodiments, the first heat dissipation member 360 includes a first heat exchange part 360a and a second heat exchange part 360b connected by bending, the first heat exchange part 360a is in thermal contact with the light source assembly 32, and the second heat exchange part 360b is in thermal contact with the second heat dissipation member 362.

[0074] It can be seen that the first heat exchange part 360a and the second heat exchange part 360b connected by bending can better fit the first heat dissipation member 360 with the light source assembly 32 and the second heat dissipation member 362, thereby increasing the heat exchange area of the first heat dissipation member 360 and improving the heat dissipation effect of the vehicle lamp 1. At the same time, the first heat exchange part 360a and the second heat exchange part 360b connected by bending can adapt to light source assemblies 32 of different angles and light source assemblies 32 arranged in different ways (for example, multiple light source assemblies 32 are arranged in layers), and the worker can adjust the bending angle of the first heat exchange part 360a and the second heat exchange part 360b according to the relative position of the light source assembly 32 and the second heat dissipation member 362, so as to realize the fit of the first heat exchange part 360a with the light source assembly 32 and the fit of the second heat exchange part 360b with the second heat dissipation member, thereby making the setting position of the light source assembly 32 in the lamp housing 10 more flexible, making the internal structure of the vehicle lamp 1 more compact, and facilitating the miniaturization design of the vehicle lamp 1.

[0075] It can be understood that the first heat exchange part 360a can be completely fitted with the light source assembly 32 to increase the heat exchange area of the first heat exchange part 360a and improve the heat dissipation effect of the vehicle lamp 1, or part of the first heat exchange part 360a can be fitted with the light source assembly 32 to reduce the occupied space of the first heat exchange part 360a in the mounting cavity 12, thereby facilitating the miniaturization design of the vehicle lamp 1.

[0076] As shown in Figure 6As shown, in some embodiments, the first mounting port 14 and the second mounting port 16 are respectively formed at the front and rear ends of the lamp shell 10, the plurality of light source assemblies 32 are arranged in the up-down direction, each optical element 34 is located at the lower side of the corresponding light source assembly 32, and each first heat exchange part 360a is matched at the upper side of the corresponding light source assembly 32.

[0077] It can be seen that the staff can first assemble the light source assembly 32, the optical element 34 and the heat dissipation component into an integral whole in the external environment, and then assemble the optical component 30 into the mounting cavity 12 through the first mounting port 14 at the front end of the lamp shell 10, so that the heat dissipation assembly 36 and the second mounting port 16 are fixedly connected, thereby facilitating the simplification of the assembly process of the vehicle lamp 1.

[0078] In addition, the plurality of light source assemblies 32 are arranged in the up-down direction, each optical element 34 is located at the lower side of the corresponding light source assembly 32, so that the light emitted by the light source assembly 32 can pass through the optical element 34 and then be emitted through the lamp cover component 20, thereby facilitating the reduction of light loss in the propagation process and improving the lighting effect of the vehicle lamp 1.

[0079] The first heat exchange part 360a is matched at the upper side of the light source assembly 32, that is, the optical element 34 and the first heat exchange part 360a are respectively located at the two sides of the light source assembly 32 in the up-down direction, so that the first heat exchange part 360a is not easy to affect the normal work of the optical element 34, and the heat generated by the light source assembly 32 in the work can be quickly transmitted to the second heat exchange part 360b through the first heat exchange part 360a, and then the heat is dissipated to the outside of the vehicle lamp 1 through the second heat dissipation part 362, so that the vehicle lamp 1 is more stable in operation.

[0080] According to the vehicle 2 of the second aspect of the present application, the vehicle 2 comprises the vehicle lamp 1 of the first aspect of the present application.
