[0042] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0043] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connection" should be understood in a broad sense, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or electrically connected or can communicate with each other; it can be directly connected, or indirectly connected through an intermediate medium, or the internal communication of two elements or the interaction relationship between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

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

[0045] In the prior art, after the touch film is used for a long time, the vehicle lamp (housing) is prone to loosen, which is not conducive to the stability of the overall installation of the vehicle lamp, and abnormal noise is prone to occur during vehicle driving.

[0046] To solve the above technical problems, the embodiment of the present application provides a vehicle lamp module, comprising: a shell, a light distribution lens and a touch film, the shell has a containing cavity and a supporting surface, the shell is arranged on a mounting surface through the supporting surface; the light distribution lens cover is arranged on the shell to block the containing cavity, the light distribution lens is adjacent to the supporting surface; the touch film is arranged on the light-incident surface of the light distribution lens, and the touch film is arranged on the side of the light distribution lens close to the supporting surface. Details are described below.

[0047] Referring to Figure 1 and Figure 2 In an embodiment, the vehicle lamp module comprises: a shell 10, a light distribution lens 20 and a touch film 100, the shell 10 has a containing cavity 11 and a supporting surface 12, the shell 10 is arranged on a mounting surface through the supporting surface 12; the light distribution lens 20 cover is arranged on the shell 10 to block the containing cavity 11, the light distribution lens 20 is adjacent to the supporting surface 12; the touch film 100 is arranged on the light-incident surface of the light distribution lens 20, and the touch film 100 is arranged on the side of the light distribution lens 20 close to the supporting surface 12.

[0048] The shell 10 is arranged on the mounting surface through the supporting surface 12, the contact area of the supporting surface 12 and the mounting surface is large, which effectively improves the stability of the shell 10 and the assembly efficiency of the shell 10. In actual use, different content display is realized by touching the touch film 100, for example, when the vehicle lamp module is applied to an interior lamp, the display content can be vehicle state related information such as air conditioner temperature, air volume, volume, etc. Since the touch film 100 is arranged on the side of the light distribution lens 20 close to the supporting surface 12, the stability of the shell 10 installation can be ensured when the touch film 100 is touched. When the touch film 100 is arranged on the side of the light distribution lens 20 away from the supporting surface 12, an acting force is generated on the light distribution lens 20 when the touch film 100 is touched, and the distance between the acting force and the supporting surface 12 is far (in this embodiment, the distance between the acting force generated by the touch film 100 on the light distribution lens 20 and the supporting surface 12 is short), that is, the force arm of the acting force is long. Under the same size of the acting force, the farther the touch film 100 is away from the supporting surface 12, the greater the torque is, 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 stability of the shell 10 installation, avoid the loosening of the shell 10 after a long time of use, avoid the abnormal sound of the vehicle, and also ensure the display quality.

[0049] At the same time, the touch film 100 is arranged on the side of the light distribution 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 light distribution lens 20, and the touch film 100 does not occupy the display area of the light distribution lens 20, the light distribution lens 20 has a large display area, and the display effect is improved.

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

[0051] Referring to Figure 1 , Figure 3 , Figure 9 and Figure 11 , in an embodiment, a buffer structure 40 is arranged between the housing 10 and the light distribution mirror 20, the buffer structure 40 comprising a mounting seat 41 and an elastic member 42, the mounting seat 41 being arranged on the housing 10, and the elastic member 42 being connected to the mounting seat 41; when the light distribution mirror 20 is covered on the housing 10, the light entrance surface of the light distribution mirror 20 is crimped on the elastic member 42, so that the elastic member 42 is deformed.

[0052] When the light distribution mirror 20 is installed on the housing 10, the light distribution mirror 20 presses the elastic member 42 arranged on the mounting seat 41 and deforms the elastic member 42, and the elastic member 42 will exert a force on the light distribution mirror 20 from the light entrance surface of the light distribution mirror 20 to the light exit surface, which can ensure the stability of the installation of the light distribution mirror 20 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, and the vibration or external force during the driving of the vehicle will cause the light distribution mirror 20 to shake with the housing 10. By deforming the elastic member 42 to exert a force on the light distribution mirror 20, the light distribution mirror 20 can be resisted, avoiding the shaking between the light distribution mirror 20 and the housing 10 and the abnormal sound during the driving of the vehicle, ensuring the stability of the installation of the light distribution mirror 20 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 axis of the mounting hole 411 being perpendicular to the light entrance surface of the light distribution mirror 20, and the elastic member 42 being inserted into the mounting hole 411; when the elastic member 42 is deformed, the mounting hole 411 can limit the position of the elastic member 42 in the radial direction of the mounting hole 411, avoiding excessive radial displacement of the elastic member 42 when it is deformed, which is not conducive to the stability of the light distribution mirror 20.

[0054] Referring to Figure 3 and Figure 7 , in an embodiment, the light distribution mirror 20 is connected to the housing 10 through the fixing structure 30; the fixing structure 30 comprises a fixing groove 31, a fixing block 32 and a fixing buckle 33, the fixing grooves 31 being arranged on one side of the housing 10 facing the light distribution mirror 20, the fixing block 32 being arranged on the groove wall of the fixing groove 31, and the fixing buckle 33 being arranged on the light entrance surface of the light distribution mirror 20; the fixing buckle 33 is inserted into the fixing groove 31, and the fixing buckle 33 is buckled on the fixing block 32 to limit the relative position of the light distribution mirror 20 and the housing 10.

[0055] The fixing structure 30 can ensure that the light distribution lens 20 is fixedly installed on the shell 10, and has simple structure and convenient installation. The fixing groove 31 is arranged on the side of the shell 10 facing the light distribution lens 20 (i.e. the side of the opening of the shell 10, and the light distribution lens 20 is used to block the opening), and the fixing buckle 33 is arranged on the light-incident surface of the light distribution lens 20 (i.e. the surface facing the shell 10). When the light distribution lens 20 is installed, the light distribution lens 20 is moved towards the opening of the shell 10, the fixing buckle 33 enters the fixing groove 31, and the light-incident surface of the light distribution lens 20 abuts against the elastic piece 42 (at this time, the elastic piece 42 is not stressed to deform). The light distribution lens 20 is continuously moved towards the shell 10 until the fixing buckle 33 is clamped on the fixing block 32, and at this time, the elastic piece 42 is extruded to deform. The deformed elastic piece 42 generates an action force on the light distribution lens 20 away from the shell 10, which makes the light distribution lens 20 have a tendency to move away from the shell 10, can ensure that the fixing buckle 33 and the fixing block 32 are tightly clamped, and can ensure that the light distribution lens 20 is fixedly and firmly installed.

[0056] In the embodiment, the fixing block 32 has a guide surface, and the fixing buckle 33 can better complete clamping 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 (as shown in Figure 8

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

[0058] Referring to Figure 3 and Figure 11 In an embodiment, the vehicle lamp module has a preset direction, which is parallel to the light-incident surface of the light distribution lens 20. At least two groups of positioning structures 50 are arranged between the light distribution lens 20 and the shell 10. The positioning structure 50 includes 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 light distribution lens 20, the positioning block 52 is arranged on the shell 10, and the positioning plate 51 is clamped in the positioning groove 521 to limit the relative position of the light distribution lens 20 and the shell 10 in the preset direction.

[0059] ​In this embodiment, two groups of pre-positioning structures 50 are arranged at intervals. Before the light distribution lens 20 is fixed on the shell 10 through the fixing structure 30, the relative position of the light distribution lens 20 and the shell 10 in the preset direction can be determined through the pre-positioning structure 50, facilitating the installation operation of the light distribution lens 20; the positioning plate 51 is clamped in the positioning groove 521, and the pre-positioning of the position of the light distribution lens 20 is realized.

[0060] For example, on the basis of the above embodiment, the fixing structure 30 includes a fixing groove 31, a fixing block 32, and a fixing buckle 33; when the light distribution lens 20 is installed, the light distribution lens 20 moves towards the shell 10, the positioning plate 51 moves towards the positioning groove 521, so that the positioning plate 51 is clamped in the positioning groove 521, and the relative position of the light distribution lens 20 and the shell 10 in the preset direction is limited; the light distribution lens 20 is continuously moved, the fixing buckle 33 is inserted into the fixing groove 31 and buckled with the fixing block 32, and the installation operation between the light distribution lens 20 and the shell 10 is realized.

[0061] Through the cooperation of the positioning plate 51 and the positioning groove 521, the relative position of the light distribution lens 20 and the shell 10 in the preset direction is limited, that is, the relative position between the fixing buckle 33 and the fixing groove 31 is limited, and after the light distribution lens 20 is pre-positioned through the positioning plate 51, the fixing buckle 33 and the fixing groove 31 can be arranged opposite to each other, that is, the fixing buckle 33 can move towards the fixing groove 31, thereby reducing the assembly difficulty.

[0062] It should be noted that in some embodiments, the positioning groove 521 can surround the circumferential side of the positioning plate 51, and when the positioning plate 51 is clamped in the positioning groove 521, the relative position of the light distribution lens 20 and the shell 10 in the preset direction can be limited, and at this time the preset direction is any direction parallel to the light-incident surface; and the pre-positioning structure 50 can even be provided with 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 in the direction parallel to the plate surface of the positioning plate 51, the positioning plate can slide in the positioning groove 521, such as Figure 3 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 in the direction parallel to the plate surface of the positioning plate 51, the positioning plate can slide in the positioning groove 521, such as Figure 3 As shown in the positioning groove 521 of

[0064] Or asFigure 5 The positioning groove 521 shown is arranged such that the surfaces of the two positioning plates 51 are perpendicular to each other, which can limit the position of the lens 20 in any direction parallel to the incident light surface.

[0065] See Figure 2 and Figure 11 In one embodiment, the mounting surface is horizontally arranged, and the angle between the light-emitting surface of the light-distributing lens 20 and the supporting surface 12 is β, which satisfies: 80°≤β≤85°, such as 80°, 81°, 82°, 83°, 84°, 85°, etc.

[0066] In this embodiment, the mounting surface is horizontal, meaning the angle between the lens 20 and the horizontal plane is β. When β is less than 80°, the angle between the lens 20 and the supporting surface 12 decreases. Figure 2 From a visual perspective, the end of the lens 20 furthest from the support surface 12 (the top of the lens 20) will be more biased to the left, causing the overall center of gravity of the headlight to shift to the left. Under the influence of gravity, the housing 10 will tend to tilt to the left, which is not conducive to the stability of the housing 10 installation. Furthermore, when the value of β is less than 80°, the light emitted from the lens 20 will be deflected upwards, which is not conducive to the human eye observing the content displayed by the lens 20 in actual use. When the value of β is greater than 85°, the end of the lens 20 away from the support surface 12 (the top of the lens 20) will be more biased to the right, causing the center of gravity of the headlight to shift to the right. Under the influence of gravity, the housing 10 will tend to tilt to the right, which is not conducive to the stability of the housing 10 installation. Furthermore, when the value of β is greater than 85°, the touch area 101 corresponding to the touch diaphragm 100 will be close to the vertical state, or even facing downward (i.e., the light-emitting surface of the lens 20 faces downward), which is not conducive to the touch operation of the touch diaphragm 100, and also not conducive to the display content of the lens 20 due to the human eye's optical difference.

[0067] For example, in some embodiments, the headlight module is applied to interior lights, and the display content of the light distribution lens 20 can be vehicle status-related information such as air conditioning temperature, airflow, and volume. Different information can be adjusted by touching the touch diaphragm 100; through the aforementioned setting of the β angle range, the light distribution lens 20 can ensure that the light emitted from the light distribution lens 20 is tilted to the upper right ( Figure 2 The wide viewing angle allows drivers and passengers to easily observe the displayed content and adjust it (i.e., the touch screen 100 is easy to operate), effectively improving driving safety.

[0068] In some embodiments, the headlight module can also be applied to the B-pillar of the vehicle for functions such as secret vehicle unlocking, and is not limited to this. In some embodiments, the angle between the lens 20 and the support surface 12 can be set in other ranges, depending on the specific arrangement of the headlight, to ensure stable installation while facilitating the observation of the displayed content and the touch operation of the touch film 100 by the driver and passengers.

[0069] See Figure 2 In one embodiment, the accommodating cavity 11 includes a first sub-cavity 111 and a second sub-cavity 112 that are interconnected. The light distribution lens 20 is disposed on the first sub-cavity 111. The second sub-cavity 112 is disposed on the side of the first sub-cavity 111 away from the light distribution lens 20, and the second sub-cavity 112 is disposed at the end of the first sub-cavity 111 near the support surface 12, for accommodating the wire harness.

[0070] In this embodiment, the second sub-cavity 112 is located at the bottom ( Figure 2 From the perspective of the camera (the same below), during the assembly of the headlights, the internal wiring harness can be neatly organized in the second sub-cavity 112, avoiding a messy and disorganized appearance while also facilitating later maintenance and repair. During vehicle operation, vibrations or other external forces can cause the wiring harness to sway relative to other components in the headlight, leading to wear and tear and affecting its lifespan. Organizing the wiring harness in the second sub-cavity 112 effectively prevents large-scale swaying, reduces wear, and extends its lifespan, while also ensuring a secure connection between the wiring harness and other components. Furthermore, after the housing 10 is mounted on the vehicle body via the support surface 12, the center of gravity of the housing 10 (including the wiring harness) is biased towards the bottom due to the proximity of the wiring harness to the support surface 12, effectively improving the stability of the housing 10.

[0071] See Figure 2 and Figure 3 In one embodiment, the headlight modules have a first direction that is perpendicular to each other (e.g., Figure 2 , 3 The middle direction is shown in Z, the same below), and the second direction (as shown in Z). Figure 2 , 3 (As shown in the middle direction X, the same below) and the third direction (such as...) Figure 2 , 3 As shown in the Y direction (the same below), the first direction is perpendicular to the support surface 12, and the third direction is parallel to the touch diaphragm 100. In this embodiment, the dimensions of the first sub-cavity 111 and the second sub-cavity 112 are equal in the third direction. In some embodiments, the dimensions can be adjusted according to the arrangement of the 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, for example, 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 viewing angle (the same below) is small (the value of h1 is constant, the same below), the space left for the wiring harness will also be correspondingly smaller, which is not conducive to the organization of the wiring harness. When the ratio of h2 / h1 is greater 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. Moreover, as the longitudinal dimension of the second sub-cavity 112 increases, the center of gravity of the housing 10 and the lens 20 will also increase, which will pose a risk of tipping over when installed through the support surface 12, which is not conducive to the stability of the installation. Therefore, when 1 / 4≤h2 / h1≤1 / 2, it can ensure both the organization and storage of the wiring harness and the stability of the housing 10 installation.

[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, for example, 1, 5 / 4, 3 / 2, etc.; when the ratio of d2 / d1 is less than 1, the lateral ( Figure 2 The smaller the size (view angle, the same below), i.e., the smaller the area of ​​the support surface 12, the less stable the installation of the housing 10, and the smaller the space left for the wiring harness, which is not conducive to the arrangement of the wiring harness; 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 is not conducive to the installation of other components. Therefore, when 1≤d2 / d1≤3 / 2, the stability of the housing 10 installation can be guaranteed, while reducing the space occupied inside the headlight.

[0074] See Figures 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 in the cavity wall of the first sub-cavity 111 away from the light distribution lens 20. The printed circuit board 70 is housed in the first sub-cavity 111 through the mounting structure 80, and the printed circuit board 70 and the control board 60 are spaced apart.

[0075] The control board 60 is located on the cavity wall away from the lens 20. The distance between the control board 60 and the touch diaphragm 100 is relatively large. When the touch diaphragm 100 is connected to the control board 60 through a wire harness, the wire harness does not need to be bent excessively. 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 diaphragm 100.

[0076] In assembly, the control board 60 can be fixed on the inner wall of the shell 10 away from the light distribution mirror 20 by a fixing mode such as double-sided tape or screw connection. Since the touch film 100 is arranged opposite to the second sub-cavity 112, the second sub-cavity 112 provides an assembly space for the wire harness connection between the touch film 100 and the control board 60, which is beneficial to improve the assembly efficiency.

[0077] In the embodiment, the printed circuit board 70 is spaced apart from the control board 60, that is, there is a certain space between the printed circuit board 70 and the control board 60, which facilitates the arrangement of the wire harness between the printed circuit board 70 and the control board 60, and the wire harness can be arranged and arranged in 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 works, 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] Referring to Figure 2 , Figure 9 and Figure 10 In an embodiment, the vehicle lamp module further includes a grid support 90, which is arranged between the printed circuit board 70 and the light distribution mirror 20. The grid support 90 has a plurality of first light transmission holes 91 arranged in an array, and the portions of the printed circuit board 70 opposite to each first light transmission hole 91 are respectively provided with a first light emitting unit 71.

[0079] Through the arrangement of the grid support 90, each first light transmission hole 91 corresponds to a first light emitting unit 71, and different lighting effects can be combined by controlling the on-off of the first light emitting units 71 in different first light transmission holes 91. The first light transmission hole 91 divides an overall space into a plurality of small spaces, realizes the grid pixelization lighting effect, and can freely display text, patterns and animations.

[0080] It should be noted that a plurality of first light emitting units 71 can be arranged in each light transmission hole to improve the diversity of display, and the color of the first light emitting unit 71 is set according to the design requirements of the vehicle lamp.
