[0004] Vehicle styling is becoming increasingly three-dimensional and personalized, and linkage structures are increasingly being used. For example, headlight systems are currently trending towards different lens modules, split designs, and custom configurations. When adjusting these different lens modules, how can we ensure consistency and mitigate distortion and noise? Summary of the Invention

[0005] Based on this, it is necessary to provide a linkage adjustment device, a headlight system and a vehicle to address at least one of the above problems.

[0006] In the first aspect, the present application provides a linkage adjustment device, which includes: a mounting member; a first adjustment bracket, which is connected to the mounting member by rotation around a first axis, and has a first adjustment point, and the first adjustment point is offset relative to the first axis; a second adjustment bracket, which is connected to the mounting member by rotation around a second axis, and has a second adjustment point, and the second adjustment point is offset relative to the second axis; and a linkage adjustment bracket, which is connected to the mounting member by rotation around a third axis, and has a first linkage point with a ball head connected to the first adjustment point and a second linkage point with a ball head connected to the second adjustment point, the first linkage point and the second linkage point are respectively offset relative to the third axis, the projection of the first axis on the linkage adjustment bracket intersects with the third axis, and the projection of the second axis on the linkage adjustment bracket intersects with the third axis.

[0007] By setting up a linkage adjustment bracket, the postures of the first adjustment bracket and the second adjustment bracket can be adjusted synchronously, and the movements of the first adjustment bracket and the second adjustment bracket are consistent. In addition, by setting up a ball head connection method for the linkage adjustment bracket, the rotation direction of the linkage adjustment bracket can be different from the rotation direction of the adjustment bracket, and the third axis can intersect with the first axis and the second axis, so that the brackets of the linkage adjustment device support each other in different planes, and the structural rigidity is good. The linkage adjustment device can effectively eliminate the influence of the matching clearance and the like on the control accuracy and support stability while ensuring the movement of the mechanism. In addition, the first linkage point and the second linkage point are both spaced apart from the third axis, so that the linkage adjustment bracket has a certain width, which helps to improve the rigidity of the linkage adjustment bracket.

[0008] In some embodiments, the second radial spacing is the same as the first radial spacing; the third radial spacing between the first linkage point and the third axis is the same as the fourth radial spacing between the second linkage point and the third axis.

[0009] With this arrangement, the synchronous movement of the first adjustment bracket and the second adjustment bracket can achieve the same swing angle. When used to adjust two lens modules, the relative position of the two beams of light can be determined based on this arrangement.

[0010] In some embodiments, the second adjustment point, the second axis, the first adjustment point, and the first axis are sequentially arranged along the direction of the third axis.

[0011] With such an arrangement, the first adjustment bracket and the second adjustment bracket can be arranged vertically, and when used to adjust the two lens modules, the height and distance of the illumination range can be adjusted.

[0012] In some embodiments, the first adjustment point and the first fixing point of the first adjustment bracket, and the second adjustment point and the second fixing point of the second adjustment bracket are arranged coplanar.

[0015] With such an arrangement, the lever arm of the linkage adjustment bracket supporting the first adjustment bracket and the second adjustment bracket is short, which helps to improve the rigidity and achieve a good supporting effect.

[0016] In some embodiments, a projection of the first axis on the linkage adjustment bracket is perpendicular to the third axis, and a projection of the second axis on the linkage adjustment bracket is perpendicular to the third axis.

[0017] With this arrangement, the linkage adjustment device has high rigidity, and the linkage adjustment bracket can support the first adjustment bracket and the second adjustment bracket. When the first adjustment bracket and the second adjustment bracket need to be aligned, the linkage adjustment bracket occupies less space in the horizontal direction.

[0019] With such arrangement, the first adjustment bracket can couple two types of rotation adjustments to achieve more precise posture adjustment.

[0020] In some embodiments, the linkage adjustment device also includes a fourth adjustment member, a fifth adjustment member and a sixth adjustment member; the second adjustment bracket has a second adjustment point, a second fixed point and a fourth adjustment point, the second fixed point and the fourth adjustment point are arranged along the second axis, and the second fixed point corresponds to the second adjustment point; the ball head of the fourth adjustment member is connected to the second adjustment point and connected to the second linkage point; the ball head of the fifth adjustment member is connected to the second fixed point and connected to the mounting member; the ball head of the sixth adjustment member is connected to the fourth adjustment point and connected to the mounting member.

[0021] With this arrangement, the second adjustment bracket can couple two types of rotation adjustments to achieve more precise posture adjustment.

[0022] In some embodiments, the linkage adjustment device further comprises at least two adjustment members, each of which is ball-jointed to the third axis of the linkage adjustment bracket and is also connected to the mounting member.

[0023] With this arrangement, the linkage adjustment bracket has good rigidity and can adapt to and absorb the posture changes of the first adjustment bracket and the second adjustment bracket; when used for adjusting the lens module of the vehicle light, it can effectively control the relative position changes of the light patterns formed by different lens modules.

[0024] In some embodiments, the linkage adjustment bracket further has a driving point, and the driving point is configured between the first linkage point and the second linkage point.

[0025] With this arrangement, the linkage adjustment bracket can move in a controlled manner to drive the first adjustment bracket and the second adjustment bracket; the driving point transmits force to the first linkage point and the second linkage point in a relatively balanced manner, and the linkage adjustment bracket has better rigidity.

[0053] refer to Figure 1 , Figure 1 FIG. 1 is a partial structural diagram of a headlight system in an embodiment of the present application. In an exemplary embodiment, the headlight system 1000 includes a linkage adjustment device 1100 , a first lens module 1200 , and a second lens module 1300 .

[0054] For ease of description, a spatial rectangular coordinate system (XYZ) is established, where the X-axis direction can be considered the front-to-back direction, the Y-axis direction can be considered the left-to-right direction (or horizontal direction), and the Z-axis direction can be considered the up-down direction (or vertical direction). The first lens module 1200 and the second lens module 1300 are each configured to transmit light toward the front of the headlight. The projection direction of each lens module can be generally forward along the X-axis and can be tilted downward to illuminate the ground.

[0055] According to the design requirements of the headlight system 1000, the first lens module 1200 and the second lens module 1300 can be designed to be arranged along the Z-axis direction, and the vertical spacing between the two can be greater than 150mm, for example, in the range of 200mm to 300mm. The two modules are far apart. How to achieve adjustment between different modules with such a large span, reduce the adjustment displacement error between different modules, for example, to less than 1.5°, improve control accuracy, and meet the requirements of light pattern consistency is a technical problem that needs to be solved. At the same time, due to the large spacing between the modules, the dynamic rigidity of the linkage adjustment device will cause elastic deformation due to the excessive length of the mechanical transmission chain, and the transmission efficiency will drop significantly, for example, it may reach 62%. It is also easy to produce abnormal noise under high-speed vibration conditions, which is also a technical problem that needs to be solved.

[0056] The embodiment of the present application provides a linkage adjustment device 1100, referring to Figure 1 and Figure 6 In some embodiments, the linkage adjustment device 1100 includes a mounting member 1 , a first adjustment bracket 21 , a second adjustment bracket 31 and a linkage adjustment bracket 41 .

[0057] The mounting member 1 can be a lamp housing or a portion of the lamp housing; alternatively, the mounting member 1 is fixed to the lamp housing. The various components can be mounted within the lamp housing. The mounting member 1 can be a one-piece structure or comprise multiple assembled components.

[0058] The linkage adjustment device 1100 may include a first adjustment component 2, also referred to as a first adjustment subassembly, which may include a first adjustment bracket 21 and other connecting components. The first adjustment bracket 21 is rotatably connected to the mounting component 1 about a first axis Q1. The first axis Q1 may be substantially parallel to the XY plane and may be parallel to or offset from the Y axis. The first adjustment bracket 21 has a first adjustment point 201, which is spaced apart from the first axis Q1 by a first radial distance. For example, the first adjustment point 201 is below the first axis Q1. In other embodiments, the first adjustment point 201 is above the first axis Q1. By offsetting the first adjustment point 201 relative to the first axis Q1, a radial distance between the first adjustment point 201 and the first axis Q1 is ensured. When a force is applied to the first adjustment point 201, the dimension of this distance, i.e., the first radial distance, becomes the moment arm of the force, ensuring that the first adjustment bracket 21 rotates about the first axis Q1 in response to the torque.

[0059] The first adjustment bracket 21 can be used to install the first lens module 1200. The optical axis of the first lens module 1200 can be perpendicular to the first axis Q1. The first lens module 1200 can be located between the first adjustment point 201 and the first axis Q1.

[0060] The linkage adjustment device 1100 may include a second adjustment assembly 3, which may include a second adjustment bracket 31 and other connecting components. The second adjustment bracket 31 is rotatably connected to the mounting member 1 about a second axis Q2. The second axis Q2 may also be substantially parallel to the XY plane, parallel to the Y axis, or offset relative to the Y axis. The second adjustment bracket 31 has a second adjustment point 301, which is spaced apart from the second axis Q2 by a second radial distance. For example, the second adjustment point 301 is below the second axis Q2. In other embodiments, the second adjustment point 301 is above the second axis Q2. By offsetting the second adjustment point 301 relative to the second axis Q2, a radial distance between the second adjustment point 301 and the second axis Q2 is ensured. When a force is applied to the second adjustment point 301, the dimension of this distance, i.e., the second radial distance, becomes the moment arm of the force, ensuring that the second adjustment bracket 31 rotates about the second axis Q2 in response to the torque.

[0061] The second adjustment bracket 31 can be used to install the second lens module 1300. The optical axis of the second lens module 1300 can be perpendicular to the second axis Q2. The second lens module 1300 can be located between the second adjustment point 301 and the second axis Q2.

[0062] The plane of the second axis Q2 can be parallel to the plane of the first axis Q1, and the second axis Q2 can be parallel to the first axis Q1. When the second axis Q2 is parallel to the first axis Q1, the first adjustment bracket 21 and the second adjustment bracket 31 can rotate in the same direction. For example, the second adjustment bracket 31 is below the first adjustment bracket 21.

[0063] The second radial spacing and the first radial spacing can be the same, and the rotation radius of the second adjustment point 301 relative to the second axis Q2 is the same as the rotation radius of the first adjustment point 201 relative to the first axis Q1. The second adjustment point 301 and the first adjustment point 201 can be set to the same position change. The positions of the first axis Q1 and the second axis Q2 along the X-axis direction can be set to be the same. In other embodiments, the position change amounts of the second adjustment point 301 and the first adjustment point 201 are different, and the positions of the first axis Q1 and the second axis Q2 along the X-axis direction are different. For example, the rotation radius of the first adjustment point 201 is larger, and the position of the first adjustment point 201 can be Figure 1 The structure shown is further to the left than the second adjustment point 301 .

[0064] The linkage adjustment device 1100 may include a linkage adjustment component 4, which may include a linkage adjustment bracket 41 and other connecting parts. The linkage adjustment bracket 41 has a first linkage point 401 and a second linkage point 402. The ball head of the first linkage point 401 is connected to the first adjustment point 201, and the ball head of the second linkage point 402 is connected to the second adjustment point 301. The line connecting the first linkage point 401 and the second linkage point 402 can be determined based on the spatial position of the first adjustment point 201 and the second adjustment point 301, for example, set along the Z-axis. The linkage adjustment bracket 41 is rotatably connected to the mounting member 1 about a third axis Q3. The third axis Q3 can be parallel to the line, and the third axis Q3 can be located in a plane parallel to the XZ plane or in a plane parallel to the YZ plane. The third radial spacing between the first linkage point 401 and the third axis Q3 and the fourth radial spacing between the second linkage point 402 and the third axis Q3 can be the same. In other embodiments, the third radial spacing is different from the fourth radial spacing. For example, the third radial spacing is larger, and the first linkage point 401 is positioned to the left relative to the second linkage point 402 .

[0065] refer to Figure 1When the linkage adjustment bracket 41 rotates forward about the third axis Q3 in the X-axis direction, the first adjustment point 201 and the second adjustment point 301 also rotate forward. The first adjustment point 201 rotates forward about the first axis Q1, causing the emission direction of the first lens module 1200 to tilt forward along the XZ plane. The second adjustment point 301 rotates forward about the second axis Q2, causing the emission direction of the second lens module 1300 to tilt forward along the XZ plane.

[0066] When the linkage adjustment bracket 41 rotates backward around the third axis Q3 in the X-axis direction, the first adjustment point 201 rotates backward around the first axis Q1, driving the emission direction of the first lens module 1200 to be pressed downward along the XZ plane; the second adjustment point 301 rotates backward around the second axis Q2, driving the emission direction of the second lens module 1300 to be pressed downward along the XZ plane.

[0067] The linked adjustment bracket 41 is capable of synchronously adjusting the posture of the first adjustment bracket 21 and the second adjustment bracket 31. The movements of the first and second adjustment brackets 21 and 31 are highly consistent, and the relative positions of the light patterns formed by the first lens module 1200 and the second lens module 1300 remain unchanged. The cross-section of the rotating shaft of the linked adjustment bracket 41 is different from that of the first and second adjustment brackets 21 and 31. By providing a ball-jointed connection for the linked adjustment bracket 41, the movement is ensured, allowing the third axis Q3 to intersect with the first and second axes Q1 and Q2. The linked adjustment bracket 41 has a certain width along the Y-axis, which helps to improve the rigidity of the linked adjustment bracket.

[0068] The first and second adjustment brackets 21 and 31 can achieve specific coordinated movements based on their design dimensions and positions. This minimizes deformation during movement, ensuring precise movement. This good coordination helps prevent unusual noises.

[0069] When the distance between the first lens module 1200 and the second lens module 1300 is greater than 150 mm, the linkage adjustment device 1100 of the embodiment of the present application can maintain good linkage control. When the distance reaches 300 mm, the transmission error can still be kept less than or equal to 0.3°; when the distance is 200 mm, the transmission error can be less than or equal to 0.2°.

[0070] The second adjustment point 301, the second axis Q2, the first adjustment point 201 and the first axis Q1 can be arranged in sequence along the direction of the third axis Q3. The first adjustment bracket 21 and the second adjustment bracket 31 are arranged vertically. When used to adjust the two lens modules, the height and distance of the illumination range can be adjusted. The first linkage point 401 and the second linkage point 402 can be on the same side of the third axis Q3. When the linkage adjustment bracket 41 rotates, the first linkage point 401 and the second linkage point 402 move synchronously and have the same direction of movement in space. For example, both have a tendency to move forward along the positive direction of the X-axis, or both have a tendency to move backward along the negative direction of the X-axis. In this way, the first adjustment bracket 21 and the second adjustment bracket 31 can be driven to move in the same direction. The two linkage points are located on the same side, which helps to make the overall size of the linkage adjustment bracket 41 small.

[0071] In other embodiments, the second adjustment point 301 and the first adjustment point 201 are located between the second axis Q2 and the first axis Q1. For example, the first linkage point 401 and the second linkage point 402 may be on different sides of the third axis Q3. When the linkage adjustment bracket 41 rotates, the first linkage point 401 and the second linkage point 402 move synchronously but in different directions of movement in space. For example, when the first linkage point 401 has a tendency to move in the positive direction of the X-axis, that is, toward the front, the second linkage point 402 may have a tendency to move in the negative direction of the X-axis, that is, toward the rear; or when the first linkage point 401 has a tendency to move in the negative direction of the X-axis, that is, toward the rear, the second linkage point 402 may have a tendency to move in the positive direction of the X-axis, that is, toward the front. In this way, the first adjustment bracket 21 and the second adjustment bracket 31 can be driven to move in the same direction.

[0072] refer to Figure 2 The first adjustment bracket 21 has a first adjustment point 201, a first fixed point 202, and a third adjustment point 203. The first fixed point 202 and the third adjustment point 203 are arranged along the first axis Q1 and can be located on both sides of the first lens module 1200. The first fixed point 202 corresponds to the first adjustment point 201, and the line connecting the first fixed point 202 and the first adjustment point 201 can be perpendicular to the first axis Q1; the three points of the first adjustment bracket 21 form a right angle.

[0073] The linkage adjustment device 1100 further includes a plurality of adjustment members 5. Specifically, the first adjustment assembly 2 may include a first adjustment member 510, a second adjustment member 520, and a third adjustment member 530. One end of the adjustment member 5 may be a ball head structure, and the other end may be a connecting portion, such as a threaded portion.

[0074] The first adjustment member 510 has a ball head connected to the first adjustment point 201. The structure of the first adjustment bracket 21 at the first adjustment point 201 can be a spherical shell, and the first adjustment member 510 can include a ball head structure embedded in the spherical shell. The first adjustment member 510 is connected to the first linkage point 401 and can include a threaded portion. For example, the first adjustment assembly 2 also includes a connecting bracket 22, and the first adjustment member 510 is connected to the first linkage point 401 of the linkage adjustment bracket 41 via the connecting bracket 22.

[0075] The ball head of the second adjusting member 520 is connected to the first fixed point 202, and each point of the first adjusting bracket 21 can be a spherical shell; the second adjusting member 520 is connected to the mounting member 1. The middle part of the second adjusting member 520 can be a fixed external hexagonal nut to lock the threaded section, and a washer can be provided.

[0076] The ball head of the third adjusting member 530 is connected to the third adjustment point 203, and the third adjusting member 530 is connected to the mounting member 1. For example, the ball head structure of the third adjusting member 530 is retractable relative to the adjustment end of the third adjusting member 530. For example, the two ends of the third adjusting member 530 may be threadedly connected. By operating the adjustment end, the distance between the ball head structure and the mounting member 1 can be adjusted.

[0077] refer to Figure 3 The mounting member 1 includes a first slot structure 101, which may include two sliding slots that are opposite to each other along the Y-axis. The third adjusting member 530 may include a slider that can be confined within the first slot structure 101 and can slide along the X-axis to guide the sliding direction of the ball head structure.

[0078] The mounting member 1 also includes a second slot structure 102. The second slot structure 102 may include two slide slots that are opposite to each other along the Y-axis direction, with the two slide slots facing each other, and each slide slot may extend along the X-axis direction. The first adjustment bracket 21 may include two guide columns with the first axis Q1 as the axis, which may be called first guide columns 211, and the two guide columns are respectively arranged in corresponding slide slots, that is, in the second slot structure 102. When the third adjustment member 530 is adjusted, the posture of the guide column in the slide slot will change, for example, it will rotate around the first fixed point 202 in the XY plane. When the first adjustment point 201 is actuated, the guide column can rotate in the slide slot and maintain the spatial posture of the first axis Q1.

[0079] By setting three points on the first adjustment bracket 21, two rotation axes are realized based on the first fixed point 202. By configuring three adjustment members 5 and the movable ball head of the third adjustment member 530, the first lens module 1200 can be manually adjusted. The emission direction of the first lens module 1200 can be adjusted within the horizontal plane to achieve horizontal dimming. In addition, vertical dimming can be achieved through the linkage adjustment component 4. The first adjustment bracket 21 can couple two types of rotation adjustment to achieve more precise posture adjustment.

[0080] In other embodiments, both ends of the third adjusting member 530 may also be electrically adjusted to achieve displacement of the ball head structure relative to the mounting member 1 .

[0081] The linkage adjustment device 1100 may also include multiple bushings 50. For example, a bushing 50 may be provided at each point on the first adjustment bracket 21. The ball head structure of the adjustment member 5 is disposed within the bushing 50, enabling full rotation. The bushing 50 may be elastic, or at least one of the assembly path between the first adjustment bracket 21, the bushing 50, the adjustment member 5 and the mounting member 1, or the assembly path to the linkage adjustment bracket 41 may be loosely fitted. The linkage adjustment device 1100 can achieve linkage between the first adjustment bracket 21 and the second adjustment bracket 31.

[0082] refer to Figure 4 The linkage adjustment device 1100 may further include a fourth adjustment member 540, a fifth adjustment member 550, and a sixth adjustment member 560. These adjustment members 5 may be used to form a second adjustment assembly 3. The second adjustment assembly 3 may have a similar structure and operation to the first adjustment assembly 2.

[0083] The second adjustment bracket 31 has a second adjustment point 301, a second fixed point 302, and a fourth adjustment point 303. The second fixed point 302 and the fourth adjustment point 303 are arranged along the second axis Q2. The second fixed point 302 corresponds to the second adjustment point 301, and the line connecting the second fixed point 302 and the second adjustment point 301 can be perpendicular to the second axis Q2. The three points of the second adjustment bracket 31 form a right angle, and all three points can be spherical shells.

[0084] The fourth adjustment member 540 has a ball head connected to the second adjustment point 301, for example, via a bushing 50. The fourth adjustment member 540 is connected to the second linkage point 402 and may be fixed thereto. The fifth adjustment member 550 has a ball head connected to the second fixed point 302 and to the mounting member 1. The sixth adjustment member 560 has a ball head connected to the fourth adjustment point 303 and to the mounting member 1. Both the sixth adjustment member 560 and the third adjustment member 530 may be subassemblies of the dimming mechanism.

[0085] refer to Figure 3The mounting member 1 may include a third slot structure 103 and a fourth slot structure 104. The third slot structure 103 may include two opposing slides along the Z-axis, and the sixth adjustment member 560 may be slidably disposed within the third slot structure 103. The fourth slot structure 104 may include two opposing slides along the Y-axis. The second adjustment bracket 31 may include two guide posts, referred to as second guide posts 311, centered around the second axis Q2. These two guide posts are disposed within the two slides of the fourth slot structure 104. When the sixth adjustment member 560 is manipulated, the second axis Q2 may rotate within the fourth slot structure 104 along the XY plane around the second adjustment point 301, achieving horizontal dimming. When the linked adjustment bracket 41 moves, the guide posts within the fourth slot structure 104 and the entire second adjustment bracket 31 may rotate around the second axis Q2, achieving vertical dimming. The second adjustment bracket 31 can couple these two rotational adjustments to achieve more precise posture adjustment. The guide posts disposed within the slides help ensure balance during displacement.

[0086] refer to Figure 5 The linkage adjustment bracket 41 further includes a third fixing point 403 and a fourth fixing point 404, which are sequentially arranged along the third axis Q3. The third fixing point 403 and the fourth fixing point 404 are located between the first adjustment point 201 and the second axis Q2. This shortens the lever arm of the linkage adjustment bracket 41 supporting the first adjustment bracket 21 and the second adjustment bracket 31, thereby improving the rigidity of the linkage adjustment bracket 41.

[0087] The linkage adjustment bracket 41 also has a fifth fixing point 405 disposed on the third axis Q3. The fifth fixing point 405 is located on the side of the second adjustment point 301 facing away from the second axis Q2, for example, on the lower side along the Z-axis. The fifth fixing point 405, in conjunction with the third fixing point 403 and the fourth fixing point 404, helps support the second linkage point 402, thereby effectively supporting the second adjustment bracket 31.

[0088] The linkage adjustment device 1100 also includes at least two adjustment members 5, such as a seventh adjustment member 570 and an eighth adjustment member (not shown), and may also include a ninth adjustment member 590. These adjustment members 5 can be used to form a linkage adjustment assembly 4. The seventh and eighth adjustment members 570 can be connected to the third and fourth fixing points 403 and 404 respectively via ball joints; the ninth adjustment member 590 can be connected to the fifth fixing point 405 via ball joints. Each adjustment member 5 is connected to the mounting member 1. Each adjustment member 5 is connected to the linkage adjustment bracket 41 along a linear ball joint at the third axis Q3, ensuring that the linkage adjustment bracket 41 can rotate about the third axis Q3. The linkage adjustment device 1100 can adapt to and absorb changes in the posture of the first and second adjustment brackets 21 and 31. When used to adjust the lens modules of a vehicle light, it can effectively control the relative position changes of the light patterns formed by different lens modules.

[0089] The linkage adjustment bracket 41 can be made of ADC12 (JIS H 5302-2006). The first and second adjustment brackets 21 and 31 can also be made of ADC12. For example, the linkage adjustment bracket 41 can be die-cast. Die-cast from 12-gauge aluminum, the linkage adjustment bracket 41 offers excellent rigidity. Reinforcement ribs can be integrally formed. Each point is designed to have at least one angled structure within the YZ plane, with at least two edges of the angled structure designed as flanged edges.

[0090] The linkage adjustment bracket 41 may further include a driving point 406, which is positioned between the first linkage point 401 and the second linkage point 402, for example, in the middle. The linkage adjustment bracket 41 is capable of controlled movement to drive the first and second adjustment brackets 21 and 31. The driving point 406 transmits force evenly to the first and second linkage points 401 and 402, resulting in a relatively strong rigidity of the linkage adjustment bracket 41.

[0091] The linkage adjustment bracket 41 can form a first frame structure above the driving point 406 along the Z-axis, and a second frame structure below the driving point 406. The first frame structure is connected to the first linkage point 401. The second frame structure can have a step difference along the X-axis from the first frame structure to avoid the second adjustment assembly 3 and the second lens module 1300.

[0092] The linkage adjustment bracket 41 may further include a third guide post 411. The third guide post 411 and the third axis Q3 are located on either side of the driving point 406. The mounting member 1 may include a sixth slot structure 106. The third guide post 411 is capable of swinging within the sixth slot structure 106. The restraint of the third guide post 411 by the sixth slot structure 106 helps to increase the rigidity of the linkage adjustment bracket 41. The third guide post 411 may be located between the first frame structure and the second frame structure.

[0093] Exemplarily, the second adjustment point 301, the second fixed point 302, the first adjustment point 201, and the first fixed point 202 are substantially located within the same operating plane parallel to the XZ plane, and the driving point 406 may also be relatively close to this operating plane. The first axis Q1 and the second axis Q2 may be parallel, for example, the first axis Q1 and the second axis Q2 are coplanar within a plane parallel to the YZ plane, and the third axis Q3 is perpendicular to the first axis Q1. The linkage adjustment bracket 41 is relatively small and compact, making it easy to adjust the control accuracy of the first adjustment bracket 21 and the second adjustment bracket 31. In other embodiments, the posture of each axis may be designed or adjusted to be non-horizontal and non-vertical.

[0094] When the second adjustment point 301, the second fixing point 302, the first adjustment point 201, and the first fixing point 202 are arranged coplanar, this plane can be tilted relative to the Y-axis; the third axis Q3 can also be tilted relative to the Y-axis to be roughly parallel to this plane. For example, the three points of the first adjustment bracket 21 can form an obtuse angle, and the three points of the second adjustment bracket 31 can also form an obtuse angle. The arrangement direction of the two adjustment brackets can be tilted relative to the Z-axis, achieving different layouts.

[0095] The headlight system 1000 provided in the embodiment of the present application includes a linkage adjustment device 1100, a first lens module 1200 and a second lens module 1300. The linkage adjustment device 1100 is the aforementioned linkage adjustment device 1100. The first lens module 1200 is arranged on the first adjustment bracket 21, for example, in the middle. The second lens module 1300 is arranged on the second adjustment bracket 31, for example, in the middle. The first lens module 1200 and the second lens module 1300 can be linkage-adjusted by the linkage adjustment device 1100, and the light patterns of the first lens module 1200 and the second lens module 1300 are consistent. The first lens module 1200 and the second lens module 1300 can be manually adjusted along the horizontal plane and then fixed at a certain position.

[0096] The headlight system 1000 may further include a drive motor 1400. The drive motor 1400 is used to drive the linkage adjustment bracket 41 to rotate about the third axis Q3, electrically controlling the first lens module 1200 and the second lens module 1300. When the first lens module 1200 and the second lens module 1300 are arranged vertically, the headlight beam can be electrically adjusted.

[0097] The drive motor 1400 may include a stator and a mover. The drive motor 1400 may be a linear motor, and the mover can slide relative to the stator along the X-axis direction, and the end of the mover may be a ball head structure. For example, the stator is threadedly connected with a ball head structure, and after the mover drives the stator to rotate, the ball head structure is displaced relative to the stator along the X-axis direction. The ball head structure of the drive motor 1400 can be connected to the drive point 406 by a ball head, for example, connected to the drive point 406 through a motor ball seat 60. The motor ball seat 60 may be provided with a slide groove, and the ball head structure of the mover can be slidably connected to the motor ball seat 60 along the Y-axis direction.

[0098] The linkage adjustment device 1100 may further include a drive bracket 6. The mounting member 1 may include a fifth slot structure 105. The drive bracket 6 may be slidably connected within the fifth slot structure 105 along the X-axis direction. The fifth slot structure 105 may include two slide grooves opposing each other along the Z-axis direction to constrain the slider of the drive bracket 6. The mover of the drive motor 1400 may be connected to the drive bracket 6, helping to drive the linkage adjustment bracket 41 to move along the X-axis direction. Exemplarily, the mounting member 1 is connected to the drive point 406 of the linkage adjustment bracket 41 via the drive motor 1400, the drive bracket 6, and the motor ball seat 60.

[0099] The drive bracket 6 can be clamped on both sides along the Y-axis and can be adjusted along the X-axis or Z-axis. The drive motor 1400 propels the drive bracket 6 within the fifth slot structure 105, and the motor ball seat 60 drives the linkage adjustment bracket 41 to rotate along the third axis Q3 formed by the third fixed point 403 and the fifth fixed point 405. The drive point 406 achieves spatial displacement.

There may be two or more lampshades 1010. For example, the upper lampshade 1010 is used to cover the first lens module 1200 and transmit light, and the lower lampshade 1010 is used to cover the second lens module 1300 and transmit light.

[0102] The headlight system 1000 may further include a vertical daytime running light device 1600 and a starry sky light device 1700 .

[0103] The upper lampshade 1010 can cover the first lens module 1200 and the upper and lower daytime running light devices 1500 .

[0104] refer to Figure 9 The headlight system 1000 may further include a housing 1030, which may be disposed between the mounting member 1 and the lampshade 1010. The housing 1030 may have a channel corresponding to the first lens module 1200. The inner wall of the channel may be flared and may be provided with a scattering layer.

[0105] refer to Figures 10 to 12In an embodiment of the present application, an adjustment assembly is provided for separately adjusting the first lens module 1200 or the second lens module 1300. Two adjustment assemblies can be provided to correspond to the two lens modules.

[0106] The adjustment assembly may include a first adjustment bracket 21 having a first adjustment point 201, a first fixing point 202, and a driving point 406. The three points may be arranged substantially in a right triangle and may surround the first lens module 1200. The first adjustment point 201 and the first fixing point 202 may define a first axis Q1.

[0107] At the first adjustment point 201, a first adjustment member 510 can be provided via a bushing 50. At the first fixed point 202, a second adjustment member 520 can be provided via another bushing 50. The ball-shaped structures of the two adjustment members 5 ensure that the first adjustment bracket 21 can rotate about the first axis Q1. The adjustment assembly may also include a locking cover 23 for locking the corresponding bushing 50 at the corresponding point. The first adjustment member 510 and the second adjustment member 520 can be respectively provided on the mounting member 1. The first adjustment member 510 can be indirectly provided on the mounting member 1 via the connecting bracket 22. The position of the connecting bracket 22 relative to the mounting member 1 is adjustable.

[0108] The drive point 406 can be connected to the drive motor 1400 via the motor ball socket 60. The motor ball socket 60 can be snapped onto the drive point 406 along the X-axis, facilitating installation. The drive motor 1400 can be a linear stepper motor, with the mover being a telescopic rod. The drive motor 1400 can be connected to the mounting member 1, thereby being used to push or pull the drive point 406 via the motor ball socket 60. The motor ball socket 60 has a chute, and the mover of the drive motor 1400 includes a ball head that slides within the chute to ensure smooth movement of the first adjustment bracket 21.

[0109] For example, the drive motor 1400 is connected to the drive bracket 6. The drive bracket 6 may be constrained by the slot structure, and the position of the drive bracket 6 relative to the mounting member 1 is adjustable. The stator of the drive motor 1400 may be mounted on the drive bracket 6.

[0110] The adjustment assembly may further include a third adjustment member 530 , which is used to adjust the position of the driving bracket 6 , and then control the predetermined position of the driving point 406 through the driving motor 1400 and the motor ball seat 60 .

[0111] refer to Figure 11 and Figure 12The adjustment assembly also includes an adjustment knob 531. The adjustment knob 531 and the third adjustment member 530 can be meshed and driven, for example, via a bevel gear or gear plate structure. The third adjustment member 530 can be threadedly connected to the drive bracket 6. The adjustment knob 531 can be approximately perpendicular to the X-axis. Turning the adjustment knob 531 can drive the third adjustment member 530 and the drive bracket 6. The adjustment assembly achieves a combination of manual and electric adjustment.
