[0003] The vehicle light adjusting device in the related art is provided with adjusting supports to adjust the angle of the corresponding lens, so as to realize the adjustment of the light shape. However, the number of adjusting supports is large and the volume is large, which leads to a large number of parts of the vehicle light adjusting device, a large volume and a high manufacturing cost.

[0004] In order to solve the above problems, the present application provides a light adjusting structure, a vehicle light adjusting device and a vehicle, which aims to solve the problem of a large number of parts, a large volume and a high manufacturing cost of the vehicle light adjusting device in the related art.

[0005] In a first aspect, the present application provides a light adjusting structure, comprising a support, a fixing assembly, a first adjusting assembly and a second adjusting assembly; the support is recessed to form a first mounting portion and a second mounting portion, the first mounting portion is used for mounting a first lens module, and the second mounting portion is used for fixing a second lens module; one end of the fixing assembly is fixed to the first mounting portion, and the other end of the fixing assembly is used for connecting the first lens module; the first adjusting assembly is installed on the first mounting portion and connected with the first lens module, and the first adjusting assembly is used for driving the first lens module to move along a first direction relative to the fixing assembly; the second adjusting assembly is installed on the first mounting portion and connected with the first lens module, and the second adjusting assembly is used for driving the first lens module to move along a second direction relative to the fixing assembly; wherein the first direction is perpendicular to the second direction.

[0006] In the above technical solution, combined with the three-point positioning principle of mechanics, the first lens module can be precisely positioned and connected with the first mounting portion through the fixing assembly, the first adjusting assembly and the second adjusting assembly, and the position of the first lens module on the support is flexibly adjusted through the first adjusting assembly and the second adjusting assembly, so as to change the relative position between the first lens module and the second lens module, adjust the deviation of the light, and meet the different needs of the high beam and the low beam, that is, adjust the light shape of the high beam and the low beam. Secondly, compared with the adjusting supports in the related art, the volume and the occupied space of the fixing assembly, the first adjusting assembly and the second adjusting assembly in the present application are small, and no additional adjusting supports are needed, which reduces the number of parts, reduces the manufacturing cost, simplifies the light adjusting structure, and makes the whole light adjusting structure more compact to save the installation space.

[0007] With reference to the first aspect, in some possible implementation manners, the first mounting portion is provided with a first accommodating groove, a first through hole, a second through hole and a groove are arranged around the first accommodating groove, the first through hole is flush with the groove in the first direction, the second through hole is flush with the groove in the second direction, and the horizontal direction intersects with the vertical direction; the first adjusting assembly is arranged through the first through hole, the second adjusting assembly is arranged through the second through hole, and one end of the fixing assembly is fixed to the groove.

[0008] In the technical solution, the fixing assembly and the position thereof are the positioning point of the first lens module relative to the support, and the first adjusting assembly and the second adjusting assembly and the positions thereof are the movable points of the first lens module relative to the support. The two movable points are flush with the positioning point in the first direction and the second direction respectively, which can ensure that the first lens module can be adjusted in an ideal plane through the movable points, avoid movement and installation errors caused by inclination or deviation, improve the movement accuracy of the first lens module, and thus improve the accurate adjustment of the light shape. In addition, when the two movable points are flush with the positioning point in the horizontal direction and the vertical direction respectively, the force distribution on the first lens module is uniform during movement, which avoids deformation or damage caused by excessive local force, and thus ensures the service life of the first lens module.

[0009] With reference to the first aspect and the implementation manners, in some possible implementation manners, the first adjusting assembly comprises a first connecting piece, a first adjusting piece and a first fixing seat; one end of the first connecting piece is connected with the first lens module; one end of the first adjusting piece is connected with the other end of the first connecting piece, and the other end of the first adjusting piece is arranged through the first through hole; the first fixing seat is fixedly connected with the side of the first mounting portion away from the first connecting piece, and the other end of the first adjusting piece is movably connected with the first fixing seat.

[0010] In the technical solution, the rotation of the first adjusting piece can be converted into linear displacement, and the displacement amount is directly related to the pitch of the first adjusting piece. Therefore, the rotation angle of the first adjusting piece can be accurately controlled to realize fine adjustment of the first lens module in the first direction, and the adjustment accuracy is high. That is, the first lens module can be displaced by rotating the first adjusting piece, so as to realize adjustment of the light shape. In addition, the first fixing seat is fixed to the support, the other end of the first adjusting piece is movably connected with the first fixing seat, that is, the first adjusting piece can rotate relative to the first fixing seat.

[0011] With reference to the first aspect and the above implementation manner, in some possible implementation manners, the first connecting piece is in a column structure, one end of the column structure is recessed to form a limiting portion, and the limiting portion is connected with the first lens module.

[0012] In the technical solution, the limiting portion is arranged to reliably and firmly connect the first screw and the first connecting piece, and the first screw abuts against the limiting portion, that is, the limiting portion also limits the first screw, so that the first screw can be connected with the first connecting piece in place.

[0014] In the technical solution, when one end of the first adjusting piece extends into the column structure, the buckles at the through grooves of the column structure limit and fix the first adjusting piece, so as to ensure the connection reliability between the first adjusting piece and the first connecting piece. In this way, when the first adjusting piece rotates, the force exerted by the first adjusting piece can be reliably transmitted to the first connecting piece, and then transmitted to the first lens module by the first connecting piece.

[0015] With reference to the first aspect and the above implementation manner, in some possible implementation manners, the other end of the first adjusting piece is provided with a threaded portion, the first fixing seat is provided with a third through hole with a thread, and the threaded portion is arranged in the first through hole and engaged with the thread of the third through hole.

[0016] In the technical solution, when the first adjusting piece rotates, the threaded portion of the first adjusting piece is matched with the thread of the third through hole, so that the first adjusting piece drives the first lens module to correspondingly displace. The movement of the threaded portion is mechanical, and the same displacement is generated by the same number of rotations of the threaded portion each time, so that the consistency and repeatability of adjusting the position of the first lens module are ensured. In addition, when the first lens module is adjusted in place, the threaded portion and the thread of the third through hole are engaged and locked, so that the limiting purpose is achieved, so as to ensure that the first lens module can be kept at the current position after being moved in place.

[0018] In the technical solution, the rotation of the second adjusting member can be converted into linear displacement, and the displacement amount is directly related to the screw pitch of the second adjusting member, so that the fine adjustment of the first lens module in the second direction can be realized by precisely controlling the rotation angle of the second adjusting member, and the adjustment precision is high, that is, the first lens module can be displaced correspondingly by rotating the second adjusting member, so that the light shape is adjusted. Secondly, the second fixing seat is fixed on the support, and the other end of the second adjusting member is movably connected with the second fixing seat, that is, the second adjusting member can rotate relative to the second fixing seat. At this time, the second fixing seat can not only limit the rotation amplitude of the second adjusting member, but also realize the indirect connection between the second adjusting member and the support, so as to avoid the problem that the second adjusting member is separated from the support during rotation and affects the use, thereby improving the rotation reliability of the second adjusting member.

DETAILED DESCRIPTION

[0035] The technical solutions in the present application will be described clearly and exhaustively below with reference to the drawings. In the description of the embodiments of the present application, unless otherwise specified, " / " represents the meaning of or, for example, A / B can represent A or B: "and / or" in the text only represents a description of the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B, which can represent: A exists alone, A and B exist together, and B exists alone, in addition, in the description of the embodiments of the present application, "multiple" means two or more than two.

[0036] Hereinafter, the terms "first", "second", "third", etc. are used only for the purpose of description, and cannot be understood as implying or suggesting relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined with "first", "second", etc. can explicitly or implicitly include one or more of the features.

[0037] Lamps are usually configured in vehicles to achieve high beam and low beam lighting. In order to provide a better lighting effect, vehicles currently usually use a multi-lens combination to achieve high beam and low beam lighting of the vehicle. The multi-lens combination has a small size and a better lighting effect, providing strong brightness and clear lighting boundaries for the driver, and improving the driving experience. Secondly, the shape of the multi-lens combination is diversified, that is, the arrangement of the multi-lens combination can be combined according to actual needs, and the applicability is strong. For different vehicles and vehicle models, the light shape required by the vehicle is also different, and correspondingly, the vehicle is usually also provided with a vehicle light adjusting device to adjust the light shape of the multi-lens combination.

[0038] The vehicle light adjusting device in the related art usually includes a mounting bracket and a plurality of adjusting brackets, a plurality of lenses are respectively fixed on the corresponding adjusting brackets, and the plurality of adjusting brackets are connected with the mounting bracket. The mounting bracket is fixed on the target position of the vehicle body. When the light shape needs to be adjusted, the angle of the corresponding lens is adjusted through the adjusting bracket, so as to achieve the adjustment of the light shape. However, when the vehicle is provided with a plurality of lenses, the vehicle light adjusting device needs to be provided with a corresponding number of adjusting brackets, resulting in a large number of adjusting brackets, a large volume and a large occupied space of the adjusting brackets. Further, the number of parts arranged in the vehicle light adjusting device is large, the structure of the vehicle light adjusting device is complex, the volume is too large, the manufacturing cost is high, and the universality is poor. Secondly, the vehicle light adjusting device needs to install the lens on the adjusting bracket first, and then fix and install the adjusting bracket on the fixed bracket, so the assembly process is complicated.

[0039] Therefore, the embodiment of the present application provides a light adjusting structure, a vehicle light adjusting device and a vehicle. The position of the first lens module on the bracket can be flexibly adjusted through the first adjusting assembly and the second adjusting assembly, so as to change the relative position between the first lens module and the second lens module, so as to adjust the high beam and low beam light shape. The size and occupied area of the first adjusting assembly and the second adjusting assembly are small, and no additional adjusting bracket needs to be arranged, which reduces the volume of the light adjusting structure as a whole, makes it more compact, and has a lower cost.

[0040] The light adjusting structure, the vehicle light adjusting device and the vehicle provided by the embodiment of the present application will be described exemplarily in combination with the drawings.

[0041] The embodiment of the present application provides a vehicle, which comprises a vehicle body and a vehicle light adjusting device, the vehicle light adjusting device is carried on the vehicle body, and the light shape of high beam and low beam of the vehicle can be adjusted through the vehicle light adjusting device to adapt to different vehicles and vehicle models. Optionally, the vehicle light adjusting device can be integrated in a headlamp assembly of the vehicle body to adjust the light shape of high beam and low beam of the vehicle.

[0042] In order to enable the vehicle light adjusting device to adjust the light shape of high beam and low beam, in an example, the vehicle light adjusting device can comprise a light adjusting structure and a plurality of lens modules, and the plurality of lens modules are arranged on the light adjusting structure. The lens module is used to focus, disperse or redirect the light emitted by the light source (such as a light-emitting diode, a halogen bulb or the like), thereby forming the required illumination mode of the vehicle.

[0043] In this example, when the vehicle needs to realize high beam and low beam, generally, one main lens and one or more auxiliary lenses are arranged, one of the plurality of lens modules is fixed on the light adjusting structure as the main lens, which can also be understood as a reference lens, and the remaining lens modules are installed on the light adjusting structure as auxiliary lenses, which can also be understood as adjustable lenses. The reference lens is used to preliminarily focus the light emitted by the light source, and the auxiliary lens is used to further adjust the direction and distribution of the light, and by adjusting the relative position between the main lens and the auxiliary lens, the refraction angle of the light passing through the lens can be changed, thereby realizing the control of the direction and distribution of the light to realize the uniform illumination of various different beam angles from spotlight to floodlight, and the adjustment flexibility is high. Specifically, when the distance between the main lens and the auxiliary lens increases or decreases, the focal point of the light changes, thereby affecting the propagation direction and intensity distribution of the light, adjusting the deviation of the light, and thereby meeting the different requirements of high beam and low beam, that is, adjusting the light shape of high beam and low beam.

[0044] Optionally, the shape of the light adjusting structure, the number and arrangement mode of the lens modules can be set according to the mounting position of the vehicle model. For example, assuming that the horizontal mounting position reserved for the vehicle is limited (for example, narrow) but the reserved height is high, the plurality of lens modules can be arranged on the light adjusting structure along the horizontal direction, at this time, the shape of the light adjusting structure is a vertical long strip, and the arrangement mode of the lens modules can be arranged along the same line in sequence, staggered or irregularly arranged. Assuming that the horizontal mounting position reserved for the vehicle is wide but the reserved height is limited (for example, low), the plurality of lens modules can be arranged on the light adjusting structure along the vertical direction, at this time, the shape of the light adjusting structure is a horizontal long strip, and the arrangement mode of the lens modules can be arranged along the same line in sequence, staggered or irregularly arranged. That is, the shape of the light adjusting structure, the number and arrangement mode of the lens modules provided by the present application can be set according to the mounting position of the vehicle model, and the present application does not make specific limitations in this regard.

[0045] The vehicle light adjusting device provided by the present application is described below by taking a vehicle light adjusting device including two lens modules (a first lens module and a second lens module) as an example. As shown in Figure 1 , the vehicle light adjusting device can include a light adjusting structure 1, a first lens module 2 fixed to the light adjusting structure 1, and a second lens module 3 mounted to the light adjusting structure 1. It can be understood that the first lens module 2 is fixed to the light adjusting structure, and at this time, the first lens module 2 is not adjustable as a reference lens. The second lens module 3 is mounted to the light adjusting structure 1 instead of being fixed to the light adjusting structure 1, that is, at this time, the light adjusting structure 1 is used as an adjustable lens, and the relative position between the second lens module 3 and the first lens module 2 can be adjusted by adjusting the second lens module 3 through the light adjusting structure 1, so as to adjust the deflection angle of the light, thereby realizing the adjustment of the high / low beam light shape, and the adjustment flexibility is high.

[0046] In order to flexibly adjust the position of the second lens module 3 through the light adjusting structure 1, in one example, please refer to Figure 2 and Figure 3 , the light adjusting structure 1 includes a bracket 11, the bracket 11 is recessed to form a first mounting portion 111 and a second mounting portion 112, the first mounting portion 111 is used for mounting the first lens module 2, and the second mounting portion 112 is used for fixing the second lens module 3. The first mounting portion 111 and the second mounting portion 112 on the bracket 11 are recessed designs, which can ensure that the first lens module 2 and the second lens module 3 can be accurately placed at the predetermined position, so as to reduce the position deviation, thereby realizing the accurate positioning and installation of the first lens module 2 and the second lens module 3 on the bracket 11, and the recessed design makes it easier to align the position during installation, reducing the installation time and difficulty.

[0047] Among them, the second lens module 3 is fixed on the bracket 11 as a reference lens, that is, its position on the second mounting portion 112 cannot be changed, and the second lens module 3 is used as a fixed element to preliminarily focus or disperse the light emitted by the light source, so as to ensure that the light has a certain directionality and intensity distribution when entering the subsequent optical assembly. Secondly, by fixing the second lens module 3 on the bracket 11, the consistency of the optical path can be maintained, and the light path deviation caused by external vibration or other factors can be avoided.

[0048] Optionally, the second lens module 3 can be fixed on the second mounting portion 112 through a fastener (such as a screw, a bolt, etc.). For example, Figure 3As shown, the second mounting portion 112 is provided with a second accommodating groove 112A, which is a through groove for accommodating the second lens module 3, and a plurality of threaded holes are arranged around the second accommodating groove 112A, and the corresponding positions of the second lens module 3 are also provided with a plurality of threaded holes. During installation, the second lens module 3 is placed in the second accommodating groove 112A, and the fasteners are arranged in the threaded holes of the second lens module 3 and the second accommodating groove 112A, so as to fix the second lens module 3 in the second mounting portion 112 by the fasteners, and at this time, the second lens module 3 is located in the second accommodating groove 112A. By fixing the second lens module 3 on the recessed second mounting portion 112 by the fasteners, the firmness of the second lens module 3 on the second mounting portion 112 can be stronger, thereby reducing the risk of loosening. The second lens module 3 can also be fixed on the second mounting portion 112 by buckles or other fixing structures, and the present application does not make specific limitations thereto.

[0049] It is worth noting that the second lens module 3 generally includes a lens and a heat dissipation frame body, and the lens is fixed on the heat dissipation frame body. Correspondingly, a plurality of threaded holes can be arranged on the heat dissipation frame body, and the heat dissipation frame body is fixed on the second mounting portion 112 by the fasteners. At this time, part of the heat dissipation frame body is arranged in the second accommodating groove 112A, and the second accommodating groove 112A is a through groove, thereby providing a certain heat dissipation space for the heat dissipation frame body.

[0050] The first lens module 2 is installed on the bracket 11 as an adjustable lens, that is, its position on the first mounting portion 111 can be changed, and by changing the relative position between the first lens module 2 and the reference lens (i.e., the second lens module 3), the light shape of the high beam and the low beam can be changed, thereby adapting to different vehicles or vehicle models.

[0051] In order to realize the adjustment of the first lens module 2, please refer to Figure 2 and Figure 3 As shown, the light adjusting structure 1 further includes a fixing assembly 12, a first adjusting assembly 13, and a second adjusting assembly 14. One end of the fixing assembly 12 is fixed to the first mounting portion 111, and the other end of the fixing assembly 12 is used to connect the first lens module 2. The first adjusting assembly 13 is installed on the first mounting portion 111 and connected with the first lens module 2. The second adjusting assembly 14 is installed on the first mounting portion 111 and connected with the first lens module 2.

[0052] In this example, the first lens module 2 is connected to the support 11 through the fixing assembly 12, the first adjusting assembly 13 and the second adjusting assembly 14, and can be precisely positioned and connected to the support 11 through the fixing assembly 12, the first adjusting assembly 13 and the second adjusting assembly 14 according to the three-point positioning principle of mechanics. At this time, the first lens module 2 can be partially fixed to the first mounting portion 111 through the fixing assembly 12, and the fixing assembly 12 provides a reference position (i.e., a positioning point) of the first lens module 2 relative to the support 11. The first lens module 2 is connected to the first mounting portion 111 through the first adjusting assembly 13 and the second adjusting assembly 14, and the first adjusting assembly 13 and the second adjusting assembly 14 provide an adjustable position (i.e., a movable point) of the first lens module 2 relative to the support 11.

[0053] The first adjusting assembly 13 is used to move the first lens module 2 relative to the fixing assembly 12 in a first direction, and the second adjusting assembly 14 is used to move the first lens module 2 relative to the fixing assembly 12 in a second direction to adjust the relative position between the first lens module 2 and the second lens module 3, wherein the first direction is perpendicular to the second direction.

[0054] Specifically, when the first adjusting assembly 13 and the second adjusting assembly 14 move the first lens module 2, the force is transmitted to the fixing assembly 12 through the first lens module 2. Since the fixing assembly 12 is fixed to the first mounting portion 111, the first lens module 2 will be displaced or rotated under the action of the force, thereby changing the relative position between the first lens module 2 and the second lens module 3 to adjust the deviation of the light rays, thereby meeting the different needs of high beam and low beam, i.e., adjusting the light pattern of high beam and low beam.

[0055] For example, low beam needs to ensure good lighting for the driver within a certain distance (e.g., 30-100 meters) in front while avoiding dazzling the driver of an oncoming vehicle. At this time, the first adjusting assembly 13 and the second adjusting assembly 14 move the first lens module 2 so that the light pattern formed by the first lens module 2 and the second lens module 3 has a horizontal cutoff line that can ensure that the light rays will not shine upward into the eyes of the driver of the oncoming vehicle. High beam needs to provide lighting for a longer distance (usually more than 100 meters), and at this time, the light pattern needs to be an elliptical light pattern to cover a larger illumination range. The first adjusting assembly 13 and the second adjusting assembly 14 move the first lens module 2 so that the light pattern of the first lens module 2 coincides with that of the second lens module 3 to form an elliptical light pattern.

[0056] Thus, combining the three-point positioning principle of mechanics, the first lens module 2 can achieve precise positioning and connection with the first mounting part 111 through the fixing component 12, the first adjustment component 13, and the second adjustment component 14. The position of the first lens module 2 on the bracket 11 can then be flexibly adjusted through the first adjustment component 13 and the second adjustment component 14, thereby changing the relative position between the first lens module 2 and the second lens module 3 to adjust the light deflection, thus meeting the different needs of high beam and low beam, i.e., achieving adjustment of the near and high beam beam patterns. Secondly, compared with the adjustment brackets in related technologies, the fixing component 12, the first adjustment component 13, and the second adjustment component 14 in this application are smaller in size and occupy less space, and there is no need to set up additional adjustment brackets, reducing manufacturing costs while simplifying the dimming structure 1, reducing the number of parts, and making the entire dimming structure 1 more compact, thus saving installation space.

[0057] In one example, please refer to Figures 4 to 6 As shown, the first mounting part 111 is provided with a first receiving groove 111A. The first receiving groove 111A is surrounded by a first through hole 111B, a second through hole 111C, and a groove 111D. The first through hole 111B and the groove 111D are flush with each other along a first direction AA, and the second through hole 111C and the groove 111D are flush with each other along a second direction BB. The first direction AA and the second direction BB intersect. The first adjusting component 13 passes through the first through hole 111B, the second adjusting component 14 passes through the second through hole 111C, and one end of the fixing component 12 is fixed to the groove 111D.

[0058] In this example, please refer to Figure 5 and Figure 6As shown, the bracket 11 includes oppositely arranged first and second faces, the opening of the recess 111D faces the first face of the bracket 11, the bottom wall and the side wall of the recess 111D protrude from the second face of the bracket 11, and one end of the fixing assembly 12 is fixed to the recess 111D and abuts against the side wall of the recess 111D. One end of the fixing assembly 12 is fixed to the recess 111D, at this time, the fixing assembly 12 and the position thereof are the positioning point of the first lens module 2 relative to the bracket 11, the first and second adjusting assemblies 13 and 14 are respectively arranged in the first and second through holes 111B and 111C, at this time, the first and second adjusting assemblies 13 and 14 and the positions thereof are the movement points of the first lens module 2 relative to the bracket 11. Wherein, the two movement points are respectively flush with the positioning point along the first direction AA and the second direction BB, which can ensure that the first lens module 2 can be adjusted in an ideal plane through the movement points, avoid movement and installation errors caused by inclination or deviation, improve the movement accuracy of the first lens module 2, and thus improve the accurate adjustment of the light shape. Secondly, when the two movement points are respectively flush with the positioning point along the horizontal direction AA and the vertical direction BB, the force distribution on the first lens module 2 is uniform during movement, which avoids deformation or damage caused by excessive local force, so as to ensure the service life of the first lens module 2.

[0059] Optionally, the first mounting portion 111 can be a closed frame, or an open frame as shown. Figures 4 to 6 For example, if it is desired to be consistent with the second mounting portion 112, the first mounting portion 111 can be a closed frame, at this time, the first accommodating groove 111A is a through groove in the middle of the closed frame. For another example, if it is desired to reduce weight and cost, the first mounting portion 111 can be an open frame as shown. Figures 4 to 6 Specifically, the actual needs can be set, and the application does not make specific limitations.

[0060] In one example, please refer to Figure 7 and Figure 8 As shown, the first adjusting assembly 13 includes a first connecting piece 131, a first adjusting piece 132, and a first fixing seat 133, one end of the first connecting piece 131 is connected with the first lens module 2, one end of the first adjusting piece 132 is connected with the other end of the first connecting piece 131, and the other end of the first adjusting piece 132 is arranged in the first through hole 111B. The first fixing seat 133 is fixedly connected with the face of the first mounting portion 111 away from the first connecting piece 131, and the first fixing seat 133 is movably connected with the other end of the first adjusting piece 132.

[0061] The two ends of the first connecting piece 131 are connected with the first adjusting piece 132 and the first lens module 2 respectively. When the first adjusting piece 132 rotates, the force is transmitted to the first connecting piece 131 connected with the first adjusting piece 132, so as to drive the first connecting piece 131 to rotate, and the first connecting piece 131 transmits the force to the first lens module 2. At this time, the first lens module 2 will be displaced or rotated under the action of the force. Specifically, when it is needed to move the position of the first lens module 2 in the first direction AA, the other end of the first adjusting piece 132 is rotated by a tool. At this time, the first adjusting piece 132 rotates relative to the first fixed seat 133, and simultaneously drives the first connecting piece 131 connected therewith to rotate. The first connecting piece 131 drives the first lens module 2 fixedly connected therewith to move after rotating, so as to realize the up-and-down translation of the first lens module 2 in the first direction AA, to adjust the relative position between the first lens module 2 and the second lens module 3, and to realize the adjustment of the light shape.

[0062] In this way, the rotation of the first adjusting piece 132 can be converted into linear displacement, and the displacement amount is directly related to the pitch of the first adjusting piece 132. Therefore, the fine adjustment of the first lens module 2 in the first direction AA can be realized by precisely controlling the rotation angle of the first adjusting piece 132, and the adjustment accuracy is high. That is, the first lens module 2 can be displaced correspondingly by rotating the first adjusting piece 132, so as to realize the adjustment of the light shape. Secondly, the first fixed seat 133 is fixed to the support 11, and the other end of the first adjusting piece 132 is movably connected with the first fixed seat 133. That is, the first adjusting piece 132 can rotate relative to the first fixed seat 133. At this time, the first fixed seat 133 can limit the rotation amplitude of the first adjusting piece 132, and can also realize the indirect connection between the first adjusting piece 132 and the support 11, so as to avoid the problem that the first adjusting piece 132 is separated from the support 11 during the rotation process and affects the use, thereby improving the rotation reliability of the first adjusting piece 132.

[0063] In order to enable the first adjusting piece 132 to rotate relative to the first fixed seat 133, in one example, as shown in Figure 8 the other end of the first adjusting piece 132 is provided with a threaded portion 132A, the first fixed seat 133 is provided with a third through hole 133A having a thread, and the threaded portion 132A is arranged in the first through hole 111B and is engaged with the thread of the third through hole 133A.

[0064] When the first adjusting member 132 is rotated in this example, the threaded portion 132A of the first adjusting member 132 is matched with the threads of the third through hole 133A, so that the first adjusting member 132 drives the corresponding displacement of the first lens module 2. The movement of the threaded portion 132A is mechanical, and the same number of rotations each time will produce the same displacement, thereby ensuring the consistency and repeatability of the adjustment of the position of the first lens module 2. Secondly, after the first lens module 2 is adjusted in place, the threads between the threaded portion 132A and the third through hole 133A are locked, thereby achieving the purpose of limiting to ensure that the first lens module 2 can remain in the current position after moving in place.

[0065] In this example, please refer to Figure 7 and Figure 8 It is shown that the first adjusting member 132 is further provided with a limiting ring 132B, which is sleeved on the body of the first adjusting member 132 and adjacent to the threaded portion 132A. When the first adjusting member 132 is threaded through the first through hole 111B, and the limiting ring 132B of the first adjusting member 132 abuts against the first mounting portion 111, it means that the first adjusting member 132 has been installed in place at this time. In this way, by providing the limiting ring 132B on the first adjusting member 132, the installation accuracy of the first adjusting member 132 installed on the first mounting portion 111 can be improved.

[0066] Optionally, the first adjusting member 132 can be an adjustable ball head screw with the above shape. It is worth noting that the rotation direction of the threaded portion 132A can be set according to requirements. For example, when the threaded portion 132A adopts the first rotation direction, when the first adjusting member 132 is rotated to the left, the first lens module 2 will move upwards; when the first adjusting member 132 is rotated to the right, the first lens module 2 will move downwards. For another example, when the threaded portion 132A adopts the second rotation direction (which is opposite to the first rotation direction), assuming that the first direction AA is the vertical direction, when the threaded portion 132A rotates the first adjusting member 132 to the left, the first lens module 2 will move downwards along the first direction AA; when the first adjusting member 132 is rotated to the right, the first lens module 2 will move upwards along the first direction AA. For this, the present application does not make specific limitations.

[0067] Optionally, other cooperation modes (such as sliding rails and sliding blocks) can also be used between the first adjusting member 132 and the first fixed seat 133, and for this, the present application does not make specific limitations.

[0068] One end of the first adjusting member 132 is fixedly connected with the first connecting member 131, and the other end of the first adjusting member 132 is rotatably connected with the first fixed seat 133, in order to realize the reliable connection of the column structure and the first adjusting member 132, and to realize the reliable transmission of force. For example, Figure 8As shown, the first connecting piece 131 can be a column structure, and a plurality of through grooves 131B are formed in the sidewall of the other end of the column structure. Each through groove 131B is provided with a buckle 131C away from the groove wall of the one end of the column structure, and the plurality of buckles 131C abut against one end of the first adjusting piece 132.

[0069] In this example, the column structure is a hollow structure, and one end of the first adjusting piece 132 extends into the hollow structure. At this time, the buckles 131C at the through grooves 131B of the column structure will limit and fix the first adjusting piece 132, so as to ensure the connection reliability between the first adjusting piece 132 and the first connecting piece 131. In this way, when the first adjusting piece 132 rotates, the force exerted by the first adjusting piece 132 can be reliably transmitted to the first connecting piece 131, and then transmitted to the first lens module 2 by the first connecting piece 131.

[0070] Optionally, the number of through grooves 131B and buckles 131C can be set according to actual needs. For example, if it is desired to improve the connection reliability between the first adjusting piece 132 and the first connecting piece 131, at least three through grooves 131B can be arranged on the sidewall of the column structure, and the corresponding buckles 131C are arranged at each through groove 131B to fix and limit the first adjusting piece 132. For another example, if it is desired to save production cost, two through grooves 131B can be arranged on the sidewall of the column structure. The number of through grooves 131B and buckles 131C can also be set according to other needs, and the present application does not make specific limitations.

[0071] In order to realize the reliable connection of the column structure and the first lens module 2, for example, Figure 8 As shown, one end of the column structure is recessed to form a limiting portion 131A, and the limiting portion 131A is connected with the first lens module 2. In order to facilitate connection, a first screw 2A is usually arranged on the first lens module 2, and the first screw 2A is fixed to the limiting portion 131A. Since the limiting portion 131A is a recessed structure, the first screw 2A can abut against the limiting portion 131A. In this way, by arranging the limiting portion 131A, the reliable and firm connection of the first screw 2A and the first connecting piece 131 can be realized, and the first screw 2A abuts against the limiting portion 131A, that is, the limiting portion 131A also limits the first screw 2A, so that the first screw 2A can be connected to the first connecting piece 131 in place.

[0072] Thus, the first connecting piece 131 can realize reliable connection with the first lens module 2 and the first adjusting piece 132 by setting the limiting part 131A and the through slot 131B, so as to ensure the reliability of force transmission from the first adjusting piece 132 to the first lens module 2 through the first connecting piece 131, thereby improving the reliability of the first lens module 2 in translation based on the rotation of the first adjusting piece 132. Optionally, the first connecting piece 131 can be a ball seat with the above shape or other structures, and the application does not make specific limitations in this regard.

[0073] Optionally, as shown in Figure 7 and Figure 8 , the first fixing seat 133 is further provided with at least one fourth through hole 133B, and the first adjusting assembly 13 further includes at least one third screw 134, and the first mounting part 111 is provided with a corresponding threaded hole at the corresponding position. The third screw 134 is arranged through the fourth through hole 133B and the threaded hole on the first mounting part 111, so as to realize reliable and stable connection of the first fixing seat 133 and the bracket 11. The first fixing seat 133 can also adopt other structures, and the application does not make specific limitations in this regard.

[0074] It is worth noting that compared with the adjusting bracket in the related art, the volume and the occupied area of the first adjusting piece 132 provided by the application are smaller, so that the overall structure of the light adjusting structure is more compact, and the manufacturing cost of the first adjusting piece 132 is lower than that of the adjusting bracket, thereby saving a certain manufacturing cost.

[0075] In one example, as shown in Figure 9 , the second adjusting assembly 14 includes a second connecting piece 141, a second adjusting piece 142, and a second fixing seat 143. One end of the second connecting piece 141 is connected with the first lens module 2. One end of the second adjusting piece 142 is connected with the other end of the second connecting piece 141, and the other end of the second adjusting piece 142 is arranged through the second through hole 111C. The second fixing seat 143 is fixedly connected with the side of the first mounting part 111 away from the second connecting piece 141, and the second fixing seat 143 is movably connected with the other end of the second adjusting piece 142.

[0076] In this example, the two ends of the second connecting piece 141 are connected with the second adjusting piece 142 and the first lens module 2 respectively. When the second adjusting piece 142 rotates, the force is transmitted to the second connecting piece 141 connected with the second adjusting piece 142, so as to drive the second connecting piece 141 to rotate, and the second connecting piece 141 transmits the force to the first lens module 2. At this time, the first lens module 2 will be displaced or rotated under the action of the force. Specifically, when the first direction AA is the vertical direction, the second direction BB is the horizontal direction. When it is needed to move the position of the first lens module 2 in the second direction BB, the other end of the second adjusting piece 142 is rotated by the tool. At this time, the second adjusting piece 142 rotates relative to the second fixed seat 143, and simultaneously drives the second connecting piece 141 connected therewith to rotate. The second connecting piece 141 drives the first lens module 2 fixedly connected therewith to move after rotating, so as to realize the left-right translation of the first lens module 2 in the second direction BB, to adjust the relative position between the first lens module 2 and the second lens module 3, and to realize the adjustment of the light shape.

[0077] In this way, the rotation of the second adjusting piece 142 can be converted into linear displacement, and the displacement amount is directly related to the pitch of the second adjusting piece 142. Therefore, the fine adjustment of the first lens module 2 in the second direction BB can be realized by precisely controlling the rotation angle of the second adjusting piece 142, and the adjustment accuracy is high. That is, the first lens module 2 can be correspondingly displaced by rotating the second adjusting piece 142, so as to realize the adjustment of the light shape. Secondly, the second fixed seat 143 is fixed to the bracket 11, and the other end of the second adjusting piece 142 is movably connected with the second fixed seat 143. That is, the second adjusting piece 142 can rotate relative to the second fixed seat 143. At this time, the second fixed seat 143 can limit the rotation amplitude of the second adjusting piece 142, and can also realize the indirect connection between the second adjusting piece 142 and the bracket 11, to avoid the problem that the second adjusting piece 142 is detached from the bracket 11 during the rotation process, so as to affect the use, thereby improving the rotation reliability of the second adjusting piece 142.

[0078] It is worth noting that the directions of the first direction AA and the second direction BB can be limited according to the installation position of the light adjustment structure 1. For example, the first direction AA can be the horizontal direction, and the corresponding second direction BB is the vertical direction. Or the first direction AA is the vertical direction, and the corresponding second direction BB is the horizontal direction. Or the first direction AA and the first direction BB are both directions inclined relative to the horizontal bottom surface. The present application does not make specific limitation on this.

[0079] The second adjusting member 142 and the first adjusting member 141 both drive the first lens module 2 to move, therefore, the structure of the second adjusting member 142 can refer to the structure of the first adjusting member 141, and the function and effect of the second adjusting member 142 can refer to the function and effect of the first adjusting member 141, which will not be repeated here. The second adjusting member 142 adopts the same structure as the first adjusting member 141, which improves the universality of the first adjusting member 141, facilitates production management, and thus saves costs.

[0080] In one example, referring to FIGS. 1 and 2, Figure 7 and Figure 8 The fixing assembly 12 includes a third connecting member 121 and a fastener 122, one end of the third connecting member 121 is connected with the first lens module 2, the other end of the third connecting member 121 is connected with one end of the fastener 122, and the other end of the fastener 122 is inserted and fixed in the groove 111D. In this example, the first lens module 2 is partially fixed on the bracket 11 through the third connecting member 121 and the fastener 122, so as to provide a positioning point for the first lens module 2.

[0081] Optionally, the third connecting member 121 can adopt the ball seat shape of the first connecting member 131 described above, so as to improve the universality of the third connecting member 121 and facilitate production management. The third connecting member 121 can also adopt other structures, which will not be specifically limited herein.

[0082] In order to realize reliable connection of the first lens module 2 with the fixing assembly 12, the first adjusting assembly 13 and the second adjusting assembly 14, in one example, as shown in FIGS. 1 and 2, Figure 2 The first lens module 2 includes a lens 21 and a heat dissipation frame 22, the lens 21 is fixed on the heat dissipation frame 22, and the heat dissipation frame 22 is installed on the dimming structure 1. In this example, a plurality of threaded holes are provided on the heat dissipation frame 22, and the heat dissipation frame 22 is fixedly connected with the fixing assembly 12, the first adjusting assembly 13 and the second adjusting assembly 14 through screws, bolts and other fasteners, and is then installed on the first mounting portion 111 through the fixing assembly 12, the first adjusting assembly 13 and the second adjusting assembly 14. At this time, part of the heat dissipation frame 22 is inserted into the first accommodating groove 111A, and the first accommodating groove 111A is a through groove, which provides a certain heat dissipation space for the heat dissipation frame. In this way, the first lens module 2 can be connected with the bracket 11 through the mounting point provided by the heat dissipation frame 22 itself, without the need to set an additional dimming bracket.

[0083] Optionally, the vehicle dimming device can further include a plurality of third lens modules, which can be arranged on the bracket 11 in the vertical and horizontal directions. The number and arrangement of the third lens modules can be set according to the installation position of the vehicle model, which will not be specifically limited herein.

[0084] Compared with the related art, the present application reduces the adjusting bracket, thereby simplifying the installation process. Exemplarily, the installation steps of the vehicle light adjusting device provided by the present application are as follows: first, the first fixing seat 133 and the second fixing seat 143 are fixed at the corresponding positions of the bracket 11. Then, the first adjusting member 132 is inserted into the first through hole 111B to be movably connected with the first fixing seat 133, the second adjusting member 142 is inserted into the second through hole 111C to be movably connected with the second fixing seat 143, and the third connecting member 121 is fixed in the groove 111D. Secondly, the first connecting member 131, the second connecting member 141 and the third connecting member 121 are fixedly connected with the heat dissipation frame body 22 of the first lens module 2. Then, the installation of the lens module is as follows: first, the second lens module 3 is fixed at the second mounting portion 112 of the bracket 11, and then the first lens module 2 is installed at the first mounting portion 111 through the first connecting member 131, the second connecting member 141 and the third connecting member 121.

[0085] In summary, the present application combines the three-point positioning principle of mechanics, so that the first lens module 2 is precisely positioned and connected with the first mounting portion 111 through the fixing assembly 12, the first adjusting assembly 13 and the second adjusting assembly 14, and then the position of the first lens module 2 on the bracket 11 is flexibly adjusted through the first adjusting assembly 13 and the second adjusting assembly 14, so as to change the relative position between the first lens module 2 and the second lens module 3, adjust the deviation of light, and meet the different needs of high beam and low beam, i.e. adjust the light shape of high beam and low beam. Please refer to Figure 10 and Figure 11 , which are the light shapes of low beam and high beam adjusted by the present application. Secondly, compared with the adjusting bracket in the related art, the fixing assembly 12, the first adjusting assembly 13 and the second adjusting assembly 14 in the present application have smaller volume and occupy less space, and do not need to be provided with an additional adjusting bracket, thereby reducing the manufacturing cost, simplifying the light adjusting structure 1, reducing the number of parts, and making the whole light adjusting structure 1 more compact to save installation space. Correspondingly, there is no need to install the adjusting bracket, thereby simplifying the installation process.
