[0003] Headlights are essential components for vehicles. With economic development, users and manufacturers are increasingly demanding a superior user experience. To ensure the beam angle of installed headlights meets user needs, reliable dimming is crucial. According to headlight design specifications, low beams must be adjustable both horizontally and vertically, while high beams must at least be adjustable vertically.

[0004] Existing headlights typically use a ball nut and ball screw to form a dimming axis. Rotating the ball screw converts the rotational motion into translational motion, driving a reflector or module to rotate around the dimming axis, thereby adjusting the light. However, existing technologies lack an indication of the dimming angle, or rely on a level gauge built into the lamp to read the light adjustment position. This built-in level gauge requires extremely precise vehicle positioning during dimming, making precise dimming difficult.

DETAILED DESCRIPTION

[0037] To make the objectives, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Generally, the components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0038] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application as claimed, but merely represents selected embodiments of the present application. It should be noted that, unless there is a conflict, the various features of the embodiments of the present application may be combined with each other, and the combined embodiments are still within the scope of protection of the present application.

[0039] In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," and "right" and the like indicate positions or locations based on the positions shown in the accompanying drawings, or the positions or locations in which the product of this application is typically placed when in use, and therefore should not be construed as limiting this application. Furthermore, the terms "first," "second," and "third," etc., are used solely for purposes of distinction and should not be construed as indicating or implying relative importance.

[0040] It should also be noted that, in the description of this application, unless otherwise specified or limited, the terms "disposed" and "connected" should be understood broadly. For example, they can refer to direct connection, indirect connection through an intermediate medium, or internal connection between two components. Those skilled in the art will understand the specific meanings of these terms in this application.

[0041] An embodiment of the present application provides a dimming indication mechanism 10, as shown in Figures 1 and 2, including: a shell 11 and a sliding member 12 sliding on the shell 11 along a first direction (direction D in Figure 1), a driving component 13 is also provided on the shell 11, the driving component 13 is used to connect with the adjustment component of the vehicle light, and a transmission component 14 is also provided between the driving component 13 and the sliding member 12, so that the sliding member 12 can be driven to move through the transmission component 14 when the driving component 13 drives the adjustment component to rotate, and an indicator 15 is provided on the shell 11 along the first direction, for indicating the rotation angle of the driving component 13 according to the positional relationship between the sliding member 12 and the indicator 15.

[0042] The dimming indicating mechanism 10 provided in the embodiment of the present application is applied to automobile lamps and is used to indicate the specific angle of adjustment of the optical module when adjusting the light output angle of the automobile lamps. Specifically, the dimming indicating mechanism 10 in the embodiment of the present application includes a driving component 13, a transmission component 14 and a sliding member 12, wherein one end of the driving component 13 is connected to the driving source, and the other end of the driving component 13 is connected to the adjustment component of the lamp. The driving component 13 rotates under the drive of the driving source, driving the adjustment component to rotate, and the adjustment component drives the lamp module to rotate to achieve the adjustment of the light output angle of the lamp. On this basis, the driving component 13 is also connected to the sliding member 12 through the transmission component 14. When the driving component 13 is driven to rotate, the transmission component 14 drives the sliding member 12 to move along the first direction. Since the adjustment component and the sliding member 12 share a driving source, the sliding member 12 moves when the adjustment component rotates, that is, the rotation angle has a certain relationship with the movement distance of the sliding member 12. An indicator member 15 is also provided on the housing 11 along the first direction. During the movement of the sliding member 12, the relative position of the sliding member 12 and the indicator member 15 changes. The movement distance of the sliding member 12 can be obtained based on the relative position relationship between the sliding member 12 and the indicator member 15. Since the rotation angle has a certain relationship with the movement distance of the sliding member 12, the rotation angle of the adjustment component can be obtained, so that the dimming indicator mechanism 10 of the embodiment of the present application can display the adjustment angle of the optical module. In addition, since the dimming structure of the present application obtains the rotation angle of the driving member (that is, the rotation angle of the adjustment component) based on the sliding distance of the sliding member 12, it is not related to the state of the vehicle, so there is no requirement for the vehicle's own posture.

[0043] Among them, in order to more intuitively observe and obtain the adjustment status of the optical module, the indicator 15 can be set to an indicator mark or an indicator scale line, and the indicator mark or the indicator scale line displays a specific value at the corresponding position. The value of the adjustment angle can be directly read according to the correspondence between the sliding member 12 and the indicator 15.

[0044] It should be noted that the present application does not limit the first direction, which can be a straight line as shown in Figure 1, or a clockwise or counterclockwise circumferential direction. Specifically, when the first direction is a straight line as shown in Figure 1, the movement of the drive component 13 is rotation, and the movement of the sliding member 12 is direct motion. At this time, the drive component 13 is arranged at one end of the transmission component 14, and the transmission component 14 converts the rotational motion into direct motion. When the first direction is a clockwise or counterclockwise circular motion, the movement of the drive component 13 is rotation, and the movement of the sliding member 12 is also rotation. At this time, the transmission component 14 will transmit the rotational motion. Among them, the specific structure and connection method of the drive component 13 and the transmission component 14 are not limited in the embodiments of the present application, and those skilled in the art can make specific settings according to actual conditions.

[0045] The present application provides a dimming indicator mechanism 10, comprising a housing 11 and a slider 12 that slides on the housing 11 along a first direction. A drive assembly 13 is also disposed along the housing 11. The drive assembly 13 is connected to the adjustment assembly of the vehicle light. When the drive assembly 13 rotates, the adjustment assembly rotates, which in turn adjusts the position of the optical module, thereby adjusting the optical module. A transmission assembly 14 is also disposed between the drive assembly 13 and the slider 12. When the drive assembly 13 drives the adjustment assembly, the transmission assembly 14 drives the slider 12. The adjustment assembly and the slider share a common drive mechanism. Thus, the rotation angle of the adjustment assembly, i.e., the adjustment angle of the optical module, can be inferred based on the distance traveled by the slider 12. An indicator 15 is disposed along the housing 11 along the first direction. The indicator 15 indicates the rotation angle of the drive assembly 13 based on the positional relationship between the slider 12 and the indicator 15. During movement, the position of the slider 12 changes relative to the indicator 15. The change in the position of the slider 12 relative to the indicator 15 can be used to determine the distance traveled by the slider 12, and thus the rotation angle of the adjustment assembly. The embodiment of the present application uses a sliding member 12 that moves simultaneously with the adjustment component to realize the display of the adjusted angle of the optical module. While realizing the display of the adjusted angle of the optical module, there is no requirement for the vehicle's own posture.

[0046] Optionally, as shown in FIG. 2 and FIG. 5 , the driving assembly 13 and the transmission assembly 14 are connected via a gear assembly, so that when the driving assembly 13 rotates, the transmission assembly 14 is driven to rotate.

[0047] The driving assembly 13 moves in a rotational direction. The driving assembly 13 drives the adjusting assembly and the transmission assembly 14 at the same time. The driving assembly 13 and the transmission assembly 14 are connected via a gear assembly to transmit the rotation to the transmission assembly 14 .

[0048] As an practicable manner, the gear assembly includes a first bevel gear 131 arranged on the driving assembly 13 and a second bevel gear 141 arranged on the transmission assembly 14, the first bevel gear 131 is engaged with the second bevel gear 141, and the transmission assembly 14 also includes a screw 142 connected to the second bevel gear 141, the screw 142 extends along the first direction, and a threaded hole 121 is provided on the sliding member 12 corresponding to the screw 142 along the first direction, and the screw 142 is connected to the threaded hole 121 to drive the sliding member 12 to move along the first direction when the screw 142 rotates.

[0049] When the first direction is the D direction as shown in Figure 1, the sliding member 12 moves in a straight line, and the movement mode is direct motion. At this time, the gear assembly needs to convert the rotation mode of the driving assembly 13 into the direct motion mode of the connecting member. The gear assembly is set to the first bevel gear 131 on the driving assembly 13 and the second bevel gear 141 on the transmission assembly 14. The planes where the rotation directions of the two bevel gears are located are perpendicular to each other. The rotation direction is changed so that the rotation direction of the transmission assembly 14 is a rotation perpendicular to the first direction.

[0050] Furthermore, the transmission assembly 14 also includes a screw 142, on which a thread is arranged, which can convert the rotational motion into a linear motion. Specifically, the transmission assembly 14 also includes a screw 142 connected to the second bevel gear 141. When the second bevel gear 141 rotates, the screw 142 rotates accordingly. A threaded hole 121 is provided on the sliding member 12 corresponding to the screw 142. The screw 142 is connected to the threaded hole 121. When the screw 142 rotates with the second bevel gear 141, it drives the sliding member 12 to move along the first direction.

[0051] Setting the first direction as a straight line direction can save space occupied by the dimming indicator mechanism 10 in the width direction, and facilitates installation with the lamp body 20 of the vehicle lamp.

[0052] As an implementable manner, a plurality of weight-reducing holes 143 are provided on the screw rod 142 to reduce the weight of the screw rod 142 .

[0053] As shown in Figures 5 and 8 , multiple lightening holes 143 are provided on screw 142 to reduce the weight of screw 142 and reduce resistance during rotation. Furthermore, when screw 142 is a plastic rod manufactured using an injection molding process, the multiple lightening holes 143 can also reduce the thickness of screw 142, thereby preventing cracks or inadequate molding after cooling after injection molding.

[0054] In addition, in order to reduce the weight of the dimming indicator mechanism 10 , all components of the dimming indicator mechanism 10 , including the driving assembly 13 , the transmission assembly 14 and the sliding member 12 , can be made of plastic.

[0055] Optionally, as shown in Figures 2 and 4, a mounting groove 111 is provided on the shell 11, and the sliding member 12 is installed in the shell 11 through the mounting groove 111. The sliding member 12 includes a sliding portion 122 slidably connected to the two side walls of the shell 11, and a transmission portion 123 connected to the transmission assembly 14, and a threaded hole 121 is provided in the transmission portion 123.

[0056] The sliding member 12 is configured to include a sliding portion 122 and a transmission portion 123 . The sliding portion 122 is slidably connected to both side walls of the housing 11 to achieve sliding. The threaded hole 121 is provided in the transmission portion 123 , so that the transmission portion 123 is connected to the screw rod 142 to achieve transmission.

[0057] As an implementable method, as shown in Figures 1, 2, 4 and 6, the end of the transmission part 123 extending outside the shell 11 is connected to a pressing part 124, the sliding part 122 is elastically connected to the transmission part 123, and there is a gap between the transmission part 123 and the sliding parts 122 on both sides, so that the sliding part 12 can be installed in the shell 11 by pressing the pressing part 124.

[0058] Specifically, the sliding portion 122 is elastically connected to the transmission portion 123, and a pressing portion 124 is provided outside the transmission portion 123 extending out of the shell 11. When the sliding member 12 enters the shell 11, it first turns the side away from the pressing portion 124 toward the mounting groove 111 and then presses. Since the sliding portion 122 is elastically connected to the transmission portion 123, at this time, due to the extrusion of the side wall of the mounting groove 111, the sliding portion 122 approaches the transmission portion 123 and accumulates elastic potential energy. After the sliding portion 122 completely enters the shell 11 through the mounting groove 111, the elastic potential energy is released, and it opens outward and contacts the side wall of the shell 11.

[0059] The sliding member 12 is installed through the installation groove 111, and there is no need to reserve installation openings on both sides of the shell 11, so that the shell 11 as a whole can limit the sliding range of the sliding member 12 at both ends, and the sliding member 12 is installed by pressing, which is convenient and quick.

[0060] As an implementable method, as shown in Figures 4 and 7, two groups of retaining ribs 112 are provided on the inner side wall of the shell 11 extending along the first direction. The retaining ribs 112 are respectively located between the sliding part 122 and the transmission part 123, and the two ends of the retaining ribs 112 are connected to the side wall of the shell 11 to prevent the screw 142 from continuing to rotate when the sliding part 12 slides to the end of the retaining rib 112.

[0061] Specifically, the sliding member 12 slides along the mounting groove 111. When the sliding member 12 slides to the side wall of the housing 11, the sliding member 12 cannot continue to move due to the obstruction of the side wall. At this time, the screw 142 continues to rotate. Since the transmission part 123 is elastically connected to the sliding part 122, when the screw 142 rotates, it squeezes the transmission part 123, causing the transmission part 123 to expand outward, thereby causing the thread on the screw 142 to jump with the thread of the threaded hole 121, damaging the screw 142 and the threaded hole 121. To prevent the above situation from occurring, the embodiment of the present application is provided with two sets of retaining ribs 112 extending along the first direction on the inner side wall of the housing 11. The two sets of retaining ribs 112 are respectively located between the transmission portion 123 and the sliding portions 122 on both sides. In this way, when the sliding member 12 slides to the side wall of the housing 11, the screw 142 continues to rotate. Due to the presence of the retaining ribs 112, the transmission portion 123 cannot expand outward, and the screw 142 cannot continue to rotate, thereby avoiding damage to the threads of the screw 142 and the threaded hole 121. In addition, when the screw 142 cannot continue to rotate, the drive assembly 13 cannot continue to rotate, which is equivalent to sending a prohibition signal.

[0062] Optionally, as shown in FIG4 and FIG6 , a mounting slide 126 communicating with the threaded hole 121 is provided on one side of the transmission portion 123 away from the pressing portion 124 , so that the screw 142 enters the threaded hole 121 through the mounting slide 126 when the pressing portion 124 is pressed.

[0063] As can be seen from the above, during the installation of the sliding member 12, the sliding member 12 is pressed from top to bottom so that the sliding member 12 partially enters the shell 11, and the screw 142 needs to enter the threaded hole 121. In order to facilitate the entry of the screw 142, an installation slide 126 connected to the threaded hole 121 is provided on the side of the transmission part 123 away from the pressing part 124. When installing the sliding member 12, the screw 142 enters the threaded hole 121 through the installation slide 126.

[0064] As an practicable manner, as shown in Figures 2, 5 and 9, the drive assembly 13 includes an input member 132 and an output member 133 driven along the second direction, the input member 132 is used to connect to the drive source, the output member 133 is used to connect to the adjustment assembly, and the first bevel gear 131 is arranged on the input member 132 or the output member 133.

[0065] The drive assembly 13 is configured to drive an input member 132 and an output member 133 connected to each other, which is convenient for installation. The output member 133 can be installed between the two mounting holes first, and then the input member 132 can be installed from the other side of the shell 11. The input member 132 is connected to the output member 133. In addition, if one of them is damaged, only one needs to be replaced, avoiding the need to replace the entire component.

[0066] When the driving assembly 13 includes an input member 132 and an output member 133 , mounting holes are provided on the housing 11 corresponding to the input member 132 and the output member 133 for respectively engaging the input member 132 and the output member 133 .

[0067] Optionally, as shown in Figure 9, the input member 132 includes a driving part 134, a first bevel gear 131 and a first connecting part 135 connected in sequence, and the output member 133 includes a second connecting part 136, a mounting part 137 and an output part 138 connected in sequence, the first connecting part 135 is connected to the second connecting part 136 to drive the input member 132 and the output member 133. The driving part 134 is used to connect to the driving source, the mounting part 137 is used to connect the output member 133 to the housing 11, and the transmission part 123 is used to connect to the adjustment component.

[0068] Among them, the driving part 134 is used to connect with the driving source. When the driving source is an external hexagon, the driving part 134 can be an internal hexagon as shown in Figure 9. The first bevel gear 131 is used to connect with the second bevel gear 141 to achieve a change in the rotation direction. The first connecting part 135 is connected to the second connecting part 136 to drive the input member 132 and the output member 133 to be connected. The mounting part 137 cooperates with the mounting hole on the shell 11 to achieve the connection between the output member 133 and the shell 11. The output part 138 is used to connect with the adjusting component. When the adjusting component is an internal hexagon, the output part 138 is an external hexagon.

[0069] The above is only a specific embodiment of the present application. Those skilled in the art can make specific arrangements for the driving part 134 , the first connecting part 135 , the second connecting part 136 , the mounting part 137 and the output part 138 according to actual conditions.

[0070] As an implementable manner, as shown in FIG9 , the first connecting portion 135 is a prism, and the second connecting portion 136 is a prismatic groove. The prism extends into the prismatic groove to realize the driving of the output member 133 by the input member 132 .

[0071] The use of prisms and prismatic grooves allows the input member 132 to drive the output member 133 to rotate synchronously, with good synchronization.

[0072] Among them, the specific structure of the prism and prismatic groove is not limited in the embodiment of the present application. For example, it can be a hexagonal prism and a hexagonal hole as shown in Figure 9, or it can be a triangular prism, a quadrangular prism, etc. Those skilled in the art can set it according to actual conditions.

[0073] Optionally, as shown in FIG2 and FIG7 , an outer edge 113 is provided on the side of the housing 11 away from the sliding member 12 , and a plurality of connecting holes 114 are provided on the outer edge 113 for inserting the connecting member to connect the housing to the lamp body 20 .

[0074] In order to facilitate the connection between the dimming indication mechanism 10 and the lamp body 20, an outer edge 113 is provided on the side of the shell 11 away from the sliding member 12, and a plurality of connecting holes 114 are provided on the outer edge 113.

[0087] The present application provides a dimming indicator mechanism, wherein the driving component drives the adjusting component to rotate when the driving component rotates, and adjusts the position of the optical module when the adjusting component rotates, thereby realizing the adjustment of the optical module. When the driving component drives the adjusting component to rotate, the sliding component is driven to move by the transmission component. The adjusting component and the sliding component share a common drive, and the rotation angle of the adjusting component, that is, the adjustment angle of the optical module, can be inferred based on the distance the sliding component moves. During the movement of the sliding component, the position of the indicating component changes relative to the position of the indicating component. The movement distance of the sliding component can be determined based on the change in the position of the sliding component relative to the indicating component, thereby determining the rotation angle of the adjusting component. The embodiment of the present application uses a sliding component that moves simultaneously with the adjusting component to realize the display of the adjustment angle of the optical module. While realizing the display of the adjustment angle of the optical module, there is no requirement for the vehicle's own posture.
