[0042] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0043] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or mutual communication; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0044] The vehicle lamp module and vehicle lamp in the present application will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0045] In the prior art, after the touch film is touched and used for a long time, it is easy to cause the headlight (housing) to become loose, which is not conducive to the stability of the overall installation of the headlight and is prone to abnormal noise during vehicle driving.

[0046] In order to solve the above technical problems, the embodiment of the present application provides a vehicle lamp module, including: a housing, a photometric mirror and a touch film, the housing having a housing cavity and a supporting surface, the housing being arranged on a mounting surface through the supporting surface; a photometric mirror cover being arranged on the housing to block the housing cavity, the photometric mirror being adjacent to the supporting surface; a touch film being applied on the light incident surface of the photometric mirror, and the touch film being arranged on a side of the photometric mirror close to the supporting surface. The following is a detailed description.

[0047] See also Figure 1 and Figure 2 In one embodiment, the vehicle lamp module includes: a shell 10, a photometric lens 20 and a touch film 100, the shell 10 has a receiving cavity 11 and a supporting surface 12, and the shell 10 is arranged on the mounting surface through the supporting surface 12; the photometric lens 20 is covered on the shell 10 to block the receiving cavity 11, and the photometric lens 20 is adjacent to the supporting surface 12; the touch film 100 is laid on the light incident surface of the photometric lens 20, and the touch film 100 is arranged on the side of the photometric lens 20 close to the supporting surface 12.

[0048] The housing 10 is disposed on the mounting surface via the supporting surface 12 . The contact area between the supporting surface 12 and the mounting surface is relatively large, which effectively improves the stability of the housing 10 and the assembly efficiency of the housing 10 . In actual use, different contents are displayed by touching the touch film 100. For example, when the car light module is used for interior lights, the displayed content can be vehicle status related information such as air-conditioning temperature, air volume, volume, etc.; since the touch film 100 is arranged on the side of the photometric mirror 20 close to the supporting surface 12, when the touch film 100 is touched, the stability of the installation of the shell 10 can be guaranteed; when the touch film 100 is arranged on the side of the photometric mirror 20 away from the supporting surface 12, touching the touch film 100 will generate a force on the photometric mirror 20, and the force is far away from the supporting surface 12 (in this embodiment, the force generated by touching the touch film 100 on the photometric mirror 20 is close to the supporting surface 12), that is, the force arm of the force is longer. Under the same force, the farther the touch film 100 is from the supporting surface 12, the greater the torque, and the shell 10 is more easily pushed under the operation of touching the touch film 100, which is not conducive to the stability of the shell 10. Therefore, the setting position of the touch film 100 in this embodiment can ensure the stable installation of the housing 10, avoid the housing 10 from loosening after long-term use, avoid abnormal noise in the vehicle, and at the same time ensure the display quality.

[0049] At the same time, the touch film 100 is arranged on the side of the photosensitive lens 20 close to the supporting surface 12, that is, the touch film 100 is arranged on the edge of the light incident surface of the photosensitive lens 20. The touch film 100 will not occupy the display area of ​​the photosensitive lens 20. The photosensitive lens 20 has a larger display area, which improves the display effect.

[0050] It should be noted that torque is the product of force and lever arm, which represents the rotational effect of force.

[0051] See also Figure 1 , Figure 3 , Fig. 9 as well as Fig.11 In one embodiment, a buffer structure 40 is provided between the housing 10 and the photometric lens 20. The buffer structure 40 includes a mounting seat 41 and an elastic member 42. The mounting seat 41 is provided on the housing 10, and the elastic member 42 is connected to the mounting seat 41. When the photometric lens 20 is covered on the housing 10, the light incident surface of the photometric lens 20 is pressed against the elastic member 42, causing the elastic member 42 to deform.

[0052] When the light distribution mirror 20 is installed on the housing 10, the light distribution mirror 20 squeezes the elastic member 42 provided on the mounting seat 41 and deforms the elastic member 42. The elastic member 42 applies a force from the light incident surface of the light distribution mirror 20 toward the light exit surface to the light distribution mirror 20, which can ensure the stability of the light distribution mirror 20 installed on the housing 10. When the light distribution mirror 20 is actually installed through the fixing structure 30, there may be an assembly gap between the light distribution mirror 20 and the housing 10 after the installation is completed. The light distribution mirror 20 and the housing 10 may shake under the vibration or external force during the driving of the vehicle. The elastic member 42 is deformed to apply a force to the light distribution mirror 20, which can hold the light distribution mirror 20 in place, avoiding the shaking between the light distribution mirror 20 and the housing 10 and the abnormal noise during the driving of the vehicle, ensuring the stability of the light distribution mirror 20 installed on the housing 10, and effectively improving the light type effect of the light exit surface of the light distribution mirror 20.

[0053] In some embodiments, the mounting seat 41 has a mounting hole 411, the axial direction of the mounting hole 411 is perpendicular to the light incident surface of the photosensitive lens 20, and the elastic member 42 is inserted into the mounting hole 411; when the elastic member 42 is deformed, the mounting hole 411 can limit the radial position of the elastic member 42 in the mounting hole 411, thereby avoiding excessive radial displacement of the elastic member 42 when it is deformed, which is not conducive to the stability of the photosensitive lens 20.

[0054] See also Figure 3 and Figure 7 In one embodiment, the photometric lens 20 is connected to the housing 10 via a fixing structure 30; the fixing structure 30 includes a fixing groove 31, a fixing block 32 and a fixing buckle 33; the fixing groove 31 is arranged at intervals on the side of the housing 10 facing the photometric lens 20; the fixing block 32 is arranged on the groove wall of the fixing groove 31; the fixing buckle 33 is arranged on the light incident surface of the photometric lens 20; the fixing buckle 33 is inserted into the fixing groove 31, and the fixing buckle 33 is buckled into the fixing block 32 to limit the relative position of the photometric lens 20 and the housing 10.

[0055] The fixing structure 30 can ensure that the light distribution mirror 20 is fixedly mounted on the housing 10 , and has a simple structure and is easy to install. The fixing groove 31 is arranged on the side of the shell 10 facing the lens 20 (i.e., the peripheral side of the opening of the shell 10, and the lens 20 is used to block the opening), and the fixing buckle 33 is arranged on the light incident surface of the lens 20 (i.e., the surface facing the shell 10). When installing the lens 20, the lens 20 is moved toward the opening of the shell 10, and the fixing buckle 33 enters the fixing groove 31 until the light incident surface of the lens 20 abuts against the elastic member 42 (at this time, the elastic member 42 is not deformed by force), and the lens 20 continues to be moved toward the shell 10 until the fixing buckle 33 is clamped on the fixing block 32, at which time the elastic member 42 is squeezed and deformed; the deformed elastic member 42 will generate a force on the lens 20 to move away from the shell 10, and this force makes the lens 20 tend to move away from the shell 10, which can ensure that the fixing buckle 33 is tightly buckled with the fixing block 32, and ensure that the lens 20 is firmly fixed.

[0056] In this embodiment, the fixing block 32 has a guide surface, and the fixing buckle 33 can better connect with the fixing block 32 through the guide surface; in some embodiments, the end of the fixing buckle 33 away from the light distribution lens 20 can also be provided with a guide surface (such as Figure 8 shown), but not limited to this.

[0057] It should be noted that the number of fixing grooves 31, the arrangement position and the spacing distance between adjacent fixing grooves 31 can be comprehensively considered according to factors such as the specific size of the light distribution lens 20, and are not specifically limited here. In addition, in this embodiment, the light distribution lens 20 and the fixing buckle 33 are integrally arranged, and can be injection molded by polycarbonate material. The fixing buckle 33 has a certain elasticity, which can facilitate the clamping installation of the fixing buckle 33 and the fixing block 32.

[0058] See also Figure 3 and Fig.11 In one embodiment, the vehicle light module has a preset direction, which is parallel to the light incident surface of the photometric lens 20; at least two sets of pre-positioning structures 50 are provided between the photometric lens 20 and the housing 10, and the pre-positioning structures 50 include a positioning plate 51 and a positioning block 52, and the positioning block 52 is provided with a positioning groove 521; the positioning plate 51 is arranged on the light incident surface of the photometric lens 20, the positioning block 52 is arranged on the housing 10, and the positioning plate 51 is clamped in the positioning groove 521 to limit the relative position of the photometric lens 20 and the housing 10 in the preset direction.

[0059] In this embodiment, two groups of pre-positioning structures 50 are arranged at intervals. Before the photosensitive lens 20 is fixed on the shell 10 by the fixing structure 30, the relative position of the photosensitive lens 20 and the shell 10 in a preset direction can be determined by the pre-positioning structure 50, so as to facilitate the installation operation of the photosensitive lens 20; the pre-positioning of the position of the photosensitive lens 20 can be achieved by clamping the positioning plate 51 in the positioning groove 521.

[0060] For example, based on the above embodiment, the fixing structure 30 includes a fixing groove 31, a fixing block 32 and a fixing buckle 33; when installing the photometric lens 20, the photometric lens 20 moves toward the housing 10, and the positioning plate 51 moves toward the positioning groove 521, so that the positioning plate 51 is snapped into the positioning groove 521, thereby limiting the relative position of the photometric lens 20 and the housing 10 in a preset direction; the photometric lens 20 continues to be moved, and the fixing buckle 33 is inserted into the fixing groove 31 and snapped into the fixing block 32, thereby realizing the installation operation between the photometric lens 20 and the housing 10.

[0061] Through the cooperation between the positioning plate 51 and the positioning groove 521, the relative position of the photosensitive lens 20 and the housing 10 in a preset direction is limited, that is, the relative position between the fixing buckle 33 and the fixing groove 31 is limited. After the photosensitive lens 20 is pre-positioned by the positioning plate 51, it can ensure that the fixing buckle 33 and the fixing groove 31 are arranged relative to each other, that is, the fixing buckle 33 can be easily moved into the fixing groove 31, thereby reducing the difficulty of assembly.

[0062] It should be noted that, in some embodiments, the positioning groove 521 can surround the circumference of the positioning plate 51. At this time, when the positioning plate 51 is snapped into the positioning groove 521, the relative position of the photometric lens 20 and the shell 10 in a preset direction can be limited. At this time, the preset direction is any direction parallel to the light incident surface; and the pre-positioning structure 50 can even be set in only one group.

[0063] In some embodiments, the groove wall of the positioning groove 521 only abuts against the plate surface of the positioning plate 51, that is, the displacement of the positioning plate 51 in the direction perpendicular to the plate surface of the positioning plate 51 is limited by the positioning groove 521, and the positioning rod can slide in the positioning groove 521 in the direction parallel to the plate surface of the positioning plate 51. Figure 3 When the pre-positioning structure 50 is provided with two groups, there will be different usage scenarios, such as Figure 3 The positioning grooves 521 are arranged as shown, and the surfaces of the two positioning plates 51 are parallel to each other. When the positioning plates 51 are inserted into the positioning grooves 521, the displacement of the positioning plates 51 in a direction perpendicular to the surface of the positioning plates 51 is limited by the positioning grooves 521. The positioning plates 51 (i.e., the light distribution mirror 20) can move in a direction parallel to the surface of the positioning plates 51. During assembly, there is an assembly margin, and the positioning plates 51 can move so that the fixing buckles 33 are better inserted into the fixing grooves 31.

[0064] Or as Figure 5 The positioning grooves 521 are arranged as shown, and the surfaces of the two positioning plates 51 are perpendicular to each other, which can limit the position of the light distribution lens 20 in any direction parallel to the light incident surface.

[0065] See also Figure 2 and Fig.11 In one embodiment, the mounting surface is horizontally arranged, and the angle between the light emitting surface of the photometric lens 20 and the supporting surface 12 is β, satisfying: 80°≤β≤85°, for example, 80°, 81°, 82°, 83°, 84°, 85°, etc.

[0066] In this embodiment, the mounting surface is horizontally arranged, that is, the angle between the photometric mirror 20 and the horizontal plane is β. When the value of β is less than 80°, the angle between the photometric mirror 20 and the supporting surface 12 becomes smaller. Figure 2 In the viewing angle, the end of the photosensitive lens 20 away from the supporting surface 12 (the top of the photosensitive lens 20) will be more inclined to the left, so that the center of gravity of the entire headlight will move to the left. Under the action of gravity, the shell 10 will tend to tilt to the left, which is not conducive to the stable installation of the shell 10; and when the value of β is less than 80°, the light emitted from the photosensitive lens 20 will be deflected upward, which is not conducive to the human eye observing the display content of the photosensitive lens 20 in actual use. When the value of β is greater than 85°, the end of the lens 20 away from the supporting surface 12 (the top of the lens 20) will be more inclined to the right, so that the center of gravity of the entire headlight will move to the right. Under the action of gravity, the shell 10 will tend to tilt to the right, which is not conducive to the stable installation of the shell 10; and when the value of β is greater than 85°, the touch area 101 corresponding to the touch film 100 will be close to a vertical state, or even face downward (that is, the light-emitting surface of the lens 20 faces downward), which is not conducive to the touch operation of the touch film 100, and is not conducive to the human eye's poor vision of the display content of the lens 20.

[0067] For example, in some embodiments, the vehicle lamp module is applied to interior lamps, and the display content of the light distribution mirror 20 can be vehicle status related information such as air conditioning temperature, air volume, volume, etc., and different information can be adjusted by touching the touch film 100; the light distribution mirror 20 can ensure that the light emitted from the light distribution mirror 20 is inclined to the upper right ( Figure 2 The touch film 100 is convenient for the driver and passengers to observe the displayed content and adjust the displayed content (i.e., the operation of touching the touch film 100 is convenient), which effectively improves driving safety.

[0068] In some embodiments, the headlight module can also be used on the B-pillar of the vehicle to perform secret unlocking of the vehicle, etc., but is not limited to this; in some embodiments, the angle between the light distribution mirror 20 and the supporting surface 12 can also be set in other ranges, according to the specific layout position of the headlight, to ensure stable installation while facilitating the driver and passengers to observe the displayed content and touch the touch film 100.

[0069] See also Figure 2 In one embodiment, the accommodating cavity 11 includes a first sub-cavity 111 and a second sub-cavity 112 which are interconnected, and the light distribution mirror 20 is covered in the first sub-cavity 111; the second sub-cavity 112 is arranged on a side of the first sub-cavity 111 away from the light distribution mirror 20, and the second sub-cavity 112 is arranged at an end of the first sub-cavity 111 close to the supporting surface 12, for accommodating the wiring harness.

[0070] In this embodiment, the second sub-cavity 112 is arranged at the bottom ( Figure 2 Perspective, the same below), when assembling the headlight, the internal wiring harness can be arranged in the second sub-cavity 112, avoiding the disorder of the wiring harness, which is beautiful and convenient for later maintenance and repair; under the vibration or other external forces during the driving of the vehicle, the wiring harness will shake relative to the other components in the headlight, and the wiring harness will be worn during the shaking process, affecting the service life. By arranging the wiring harness in the second sub-cavity 112, it is possible to effectively prevent the wiring harness from shaking in a large range, reduce wear, effectively improve the service life of the wiring harness, and ensure that the wiring harness is firmly connected to each component. At the same time, after the shell 10 is installed on the vehicle body through the support surface 12, since the wiring harness is close to the support surface 12, the center of gravity of the shell 10 as a whole (including the wiring harness) is biased to the bottom, which effectively improves the stability of the shell 10.

[0071] See also Figure 2 and Figure 3 In one embodiment, the vehicle lamp modules have first directions perpendicular to each other (eg Figure 2 , 3 The middle direction Z, the same below), the second direction (as shown in Figure 2 , 3 The middle direction (shown as X, the same below) and the third direction (as Figure 2 , 3 The first direction is perpendicular to the support surface 12, and the third direction is parallel to the touch film 100. In this embodiment, the first sub-cavity 111 and the second sub-cavity 112 are equal in size in the third direction. In some embodiments, they can be adjusted according to the arrangement positions of other components.

[0072] In this embodiment, in the first direction, the size of the first sub-cavity 111 is h1 mm, and the size of the second sub-cavity 112 is h2 mm, satisfying: 1 / 4≤h2 / h1≤1 / 2, such as 1 / 4, 1 / 3, 1 / 2, etc.; when the ratio of h2 / h1 is less than 1 / 4, the longitudinal direction of the second sub-cavity 112 ( Figure 2 When the second sub-cavity 112 is larger than 1 / 2, the longitudinal dimension of the second sub-cavity 112 is larger, which will occupy more installation space inside the headlight, which is not conducive to the overall design of the headlight. As the longitudinal dimension of the second sub-cavity 112 increases, the center of gravity of the housing 10 and the light distribution mirror 20 will also increase. When the housing is installed through the support surface 12, there is a risk of tipping over, which is not conducive to the stability of the installation. Therefore, when 1 / 4≤h2 / h1≤1 / 2, both the arrangement and storage of the headlight can be guaranteed, and the stability of the installation of the housing 10 can be guaranteed.

[0073] In some embodiments, in the second direction, the size of the first sub-cavity 111 is d1 mm, and the size of the second sub-cavity 112 is d2 mm, satisfying: 1≤d2 / d1≤3 / 2, such as 1, 5 / 4, 3 / 2, etc.; when the ratio of d2 / d1 is less than 1, the lateral direction of the second sub-cavity 112 ( Figure 2 When the value of d2 / d1 is greater than 3 / 2, the lateral dimension of the second sub-cavity 112 is too large, which will occupy more space inside the headlight, and will be unfavorable for the installation of other parts. Therefore, when 1≤d2 / d1≤3 / 2, the stability of the housing 10 installation can be guaranteed, and the occupation of the internal space of the headlight can be reduced.

[0074] See also Figure 2-4 In one embodiment, the vehicle light module further includes a control board 60 and a printed circuit board 70. The control board 60 is disposed on the cavity wall of the first sub-cavity 111 away from the photometric lens 20. The printed circuit board 70 is accommodated in the first sub-cavity 111 through the mounting structure 80, and the printed circuit board 70 is spaced apart from the control board 60.

[0075] The control board 60 is arranged on the cavity wall away from the light distribution lens 20. The distance between the control board 60 and the touch film 100 is relatively large. When the touch film 100 is connected to the control board 60 through a wiring harness, the wiring harness does not need to bend transitionally. The setting of the control board 60 leaves enough installation space, which effectively improves the reliability and service life of the connection between the control board 60 and the touch film 100.

[0076] During assembly, the control board 60 can be fixed to the inner wall of the shell 10 away from the light distribution lens 20 by means of double-sided tape or screw connection. Since the touch film 100 and the second sub-cavity 112 are arranged relative to each other, the second sub-cavity 112 provides an assembly space for the wiring harness connection between the touch film 100 and the control board 60, which is conducive to improving the assembly efficiency.

[0077] In this embodiment, the printed circuit board 70 and the control board 60 are spaced apart, that is, there is a certain space between the printed circuit board 70 and the control board 60, which facilitates the arrangement of the wiring harness between the printed circuit board 70 and the control board 60, and can smoothly arrange the wiring harness into the second sub-cavity 112. In addition, the gap between the printed circuit board 70 and the control board 60 can also effectively isolate heat. When the printed circuit board 70 is working, the heat of the light-emitting unit on the printed circuit board 70 is effectively separated from the control board 60, which reduces the influence of heat on the control board 60 and effectively improves the service life.

[0078] See also Figure 2 , Fig. 9 as well as Fig.10 In one embodiment, the vehicle light module further includes a grid bracket 90, which is disposed between the printed circuit board 70 and the light distribution lens 20; the grid bracket 90 has a plurality of first light-transmitting through holes 91 arranged in an array, and the portions of the printed circuit board 70 corresponding to each first light-transmitting through hole 91 are respectively provided with first light-emitting units 71.

[0079] Through the setting of the grid bracket 90, each first light-transmitting through hole 91 corresponds to a first light-emitting unit 71, and different lighting effects can be combined by controlling the lighting of the first light-emitting units 71 in different first light-transmitting through holes 91; the first light-transmitting through holes 91 divide an overall space into multiple small spaces, achieving a grid pixelated lighting effect, and can freely display text, patterns and animations.

[0080] It should be noted that a plurality of first light-emitting units 71 may be provided in each light-transmitting through hole to enhance display diversity, and the color of the first light-emitting unit 71 is set according to the design requirements of the vehicle lamp.

[0081] For example, in some embodiments, the vehicle lights are used for displaying the air-conditioning temperature of the interior lights; when used for displaying the cooling temperature, blue light may be displayed, and when used for displaying the heating temperature, red light may be displayed.

[0082] See also Figure 2 , Fig. 9 as well as Fig.10In one embodiment, the touch film 100 is disposed between the printed circuit board 70 and the lens 20, and the touch film 100 includes a plurality of touch areas 101 arranged in sequence, and a second light-emitting unit 74 is provided at a portion of the printed circuit board 70 opposite to each touch area 101; the grid bracket 90 also has a plurality of second light-transmitting through holes 94, and a second light-transmitting through hole 94 is provided between each touch area 101 and the second light-emitting unit 74 opposite to the touch area 101.

[0083] The second light-transmitting through hole 94 can separate the second light-emitting units 74 corresponding to each touch area 101. When in use, the second light-transmitting through hole 94 can effectively avoid light interference between adjacent second light-emitting units 74; each touch area 101 corresponds to a different function icon, and the lighting of adjacent function icons will not be affected.

[0084] See also Fig. 9 In one embodiment, a vibration motor 120 is connected to the light incident surface of the light distribution lens 20 to provide feedback on the touch film 100 .

[0085] When the driver or passenger touches the touch membrane 100 , the vibration motor 120 vibrates to provide the driver or passenger with touch feedback; during driving, the driver or passenger can perform blind operations, thereby effectively improving driving safety.

[0086] It should be noted that in some embodiments, more vehicle information is displayed, that is, the length of the touch film 100 will increase accordingly. It is necessary to set multiple vibration motors 120 at intervals according to the length of the touch film 100 to ensure that there is good vibration feedback when touching different function icons on the touch film 100.

[0087] See also Figure 3-6 as well as Fig. 9 In one embodiment, the mounting structure 80 includes at least two positioning posts 81, at least two limiting posts 82, a first limiting hole 73, a connecting hole 83, a first positioning hole 72 and a connecting screw; the first positioning hole 72 and the first limiting hole 73 are arranged on the printed circuit board 70, the connecting hole 83 is arranged on the positioning post 81, and the positioning post 81 and the limiting post 82 are arranged on the inner wall of the shell 10 facing the photometric lens 20; the limiting post 82 is inserted into the first limiting hole 73 to limit the relative position of the first positioning hole 72 and the connecting hole 83 in the radial direction of the positioning post 81; the connecting screw is inserted into the first positioning hole 72 and is screwed with the connecting hole 83 to crimp the printed circuit board 70 to the end face of the positioning post 81 facing the photometric lens 20.

[0088] In this embodiment, four positioning posts 81 are provided. Through the setting of the positioning posts 81, the interval between the printed circuit board 70 and the control board 60 can be ensured. The specific effects are detailed in the aforementioned embodiments. When installing the printed circuit board 70, the first limiting hole 73 is first sleeved on the limiting post 82 to limit the printed circuit board 70 in advance to prevent its position from changing in the radial direction of the positioning post 81, which is not conducive to the installation operation. Through the cooperation of the first limiting hole 73 and the limiting post 82, the relative position of the first positioning hole 72 and the connecting hole 83 in the radial direction of the positioning post 81 is limited, which facilitates the installation of the connecting screws and improves the assembly efficiency.

[0089] It should be noted that, in some embodiments, the first limiting hole 73 can be set in a long strip shape, and the printed circuit board 70 can move in a small range, so that the first positioning hole 72 can be better matched with the connecting hole 83, and there is a certain assembly margin, thereby improving the assembly efficiency.

[0090] In some embodiments, the number of the positioning posts 81 may be six, etc., and may be set accordingly according to the size of the printed circuit board 70 to ensure that the printed circuit board 70 is stably installed.

[0091] It should be noted that, in some embodiments, a second positioning hole 92 and a second limiting hole 93 are provided on the grid bracket 90, and the grid bracket 90 is arranged on the surface of the printed circuit board 70 facing the photometric lens 20; when assembling, the printed circuit board 70 is first moved toward the positioning column 81 until the limiting column 82 is inserted into the first limiting hole 73. At this time, the first positioning hole 72 and the connecting hole 83 are arranged oppositely, and the printed circuit board 70 is limited in the radial direction of the positioning column 81, which is convenient for the subsequent connection screws and the connecting holes 83 to be connected; then the grid bracket 90 is moved toward the printed circuit board 70 until the limiting column 82 is inserted into the second limiting hole 93. At this time, the second positioning hole 92 and the connecting hole 83 are arranged oppositely, that is, the positions of the first positioning hole 72, the second positioning hole 92 and the connecting hole 83 in the radial direction of the positioning column 81 are limited, and finally, the printed circuit board 70 is fixed on the end face of the positioning column 81 facing the photometric lens 20 by fastening with the connecting screws and the connecting holes 83, and the grid bracket 90 is fixed on the surface of the printed circuit board 70 facing the photometric lens 20. By inserting the limiting column 82 into the first limiting hole 73 and the second limiting hole 93, the relative positions of the first positioning hole 72, the second positioning hole 92 and the connecting hole 83 on the positioning column 81 in the radial direction are limited, which facilitates the installation of the connecting screws and improves the assembly efficiency; and only one installation of the connecting screws is required to fix both the printed circuit board 70 and the grid bracket 90; in addition, the printed circuit board 70 and the grid bracket 90 are both positioned by the limiting column 82 and the positioning column 81, ensuring that the first light-transmitting through hole 91 is arranged relative to the first light-emitting unit 71 to ensure the lighting effect.

[0092] See also Figure 2 In one embodiment, a decorative film 110 is applied on the light emitting surface of the light distribution lens 20 .

[0093] The decorative film 110 covers the light-emitting surface of the light distribution mirror 20. When the headlight is in a static state (not lit), the headlight presents the effect of decorative patterns. At this time, the color of the decorative patterns has an important influence on the comfort brought by the matching of the whole lamp and the vehicle, and its texture is directly related to the user's experience. When the headlight is lit, the decorative film 110 will be presented with a pixelated pattern effect, such as Fig.12 On the one hand, on the basis of ensuring that the color tone of the decorative pattern is closer to the actual situation, the color of the decorative pattern should be adjusted to make the whole lamp more high-end and atmospheric; on the other hand, as far as the texture of the decorative film 110 is concerned, it is necessary to carefully select the manufacturing process of the film so that it is neither too smooth nor too rough.

[0094] At the same time, in order to ensure the light transmittance, the decorative film 110 should use a film with high transmittance to ensure that the brightness presented meets the design requirements.

[0095] On the other hand, the present application also relates to a vehicle lamp, comprising any one of the aforementioned vehicle lamp modules.

[0096] By adopting the technical solution provided in the embodiment of the present application, the shell 10 is set on the mounting surface through the supporting surface 12.
