Description

Technical Field

[0001] The present invention relates to the technical field of vehicle lamps, and in particular to a vehicle lamp adjustment system. Background Art

[0002] When a vehicle leaves the factory, its headlights are typically set to a standard illumination range. However, as the vehicle is used, the illumination direction may deviate from this standard due to vehicle load, prolonged vibration, and other factors. Therefore, an internal adjustment mechanism is required to adjust the illumination direction, thereby adjusting the illumination range and improving the lighting effect. This adjustment mechanism generally includes horizontal adjustment: adjusting the left and right direction of the light beam to adjust the width of the illuminated area. An inappropriate width will result in unfocused light; and vertical adjustment: adjusting the beam angle to adjust the height of the illumination. If the height is too high, the ground will not be illuminated clearly; if the height is too low, the illumination distance will be short.

[0003] Most existing headlight adjustment mechanisms are fixed to the lamp housing on the back side of the adjustment bracket, directly acting on the adjustment bracket to rotate the adjustment bracket in the horizontal or vertical direction to change the posture of the lamp group supported by the adjustment bracket. Due to the limited space between the adjustment bracket and the lamp housing, this fixing method limits the structural layout space of the adjustment mechanism, affecting the structural design of the headlight. In addition, the adjustable space is small, and the ratio between the adjustment amount of the adjustment mechanism and the corresponding adjustment amount of the adjustment bracket is small, resulting in poor stability of the adjustment system. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a vehicle light adjustment system that optimizes the position arrangement of the adjustment mechanism so that the adjustment mechanism is easy to install, has high adjustment stability and sufficient space.

[0005] In order to solve the above technical problems, the present invention provides a vehicle light adjustment system, comprising a lamp housing for fixedly connecting to a vehicle body, a dimming bracket arranged in a concave cavity of the lamp housing, and an adjustment mechanism for adjusting the posture of the dimming bracket, the lamp group is fixed on the dimming bracket, the adjustment mechanism comprises a horizontal adjustment mechanism for driving the dimming bracket to rotate around a vertical rotation axis and a vertical adjustment mechanism for driving the dimming bracket to rotate around a horizontal rotation axis, in the concave cavity of the lamp housing, the area where the dimming bracket and the lamp housing are opposite to form a first chamber space, the main body of the horizontal adjustment mechanism or the vertical adjustment mechanism is arranged on the outer side of the first chamber space, so that the output end of the horizontal adjustment mechanism or the vertical adjustment mechanism needs to cross a certain distance to drive the dimming bracket.

[0006] In the above-mentioned headlight adjustment system, by arranging the horizontal adjustment mechanism or the vertical adjustment mechanism on the outside side of the first chamber space, that is, on the side of the dimming bracket, the driving force of the adjustment mechanism is transmitted to the dimming bracket across a certain distance, so that the adjustment mechanism does not need to be strictly arranged in the first chamber space opposite the back side of the dimming bracket. The position arrangement is flexible and will not affect the adjustment action of the dimming bracket. The position of the adjustment mechanism can be set according to the actual environmental requirements, effectively solving the problem that conventional adjustment solutions cannot be arranged due to styling restrictions, optimizing the structural design of the headlight, better meeting the headlight styling, and also making the adjustment space of the adjustment mechanism larger and the adjustment stable.

[0007] Typically, a first universal rotation connection structure is provided between the dimming bracket and the lamp housing, allowing the dimming bracket to freely rotate about the rotation center of the first universal rotation connection structure. The horizontal adjustment mechanism drives the dimming bracket to rotate about a vertical rotation axis, which is a vertical line passing through the rotation center of the first universal rotation connection structure. The vertical adjustment mechanism drives the dimming bracket to rotate about a horizontal rotation axis, which is a horizontal line passing through the rotation center of the first universal rotation connection structure. The adjustment mechanism can be manual with a screw or electric with a motor.

[0008] Preferably, the dimming bracket is a long, uneven sheet-like structure with a certain degree of toughness. As the object being adjusted, the dimming bracket bears the force and has a certain degree of toughness to compensate for slight deviations during adjustment due to component and installation tolerances. It also serves as the main support for the lamp assembly and other structures. The uneven structure enhances strength and facilitates the installation of other components.

[0009] As an improvement to the vehicle light adjustment system of the present invention, the horizontal adjustment mechanism is arranged on one side of the dimming bracket, and a first transmission mechanism is arranged between the output end of the horizontal adjustment mechanism and the horizontal adjustment part corresponding to the dimming bracket. The first transmission mechanism is used to transmit the horizontal movement of the output end of the horizontal adjustment mechanism to the horizontal adjustment part across a certain distance, driving the dimming bracket to rotate around the vertical rotation axis.

[0010] The horizontal adjustment mechanism pushes the horizontal adjustment part to move horizontally, and usually needs to be set on the back side of the dimming bracket. This results in a small adjustable amount of the horizontal adjustment mechanism and limits the fixed installation position of the horizontal adjustment mechanism itself. Therefore, the horizontal adjustment mechanism is set on the lamp housing at a position deviated from the dimming bracket, that is, it is set on one side of the dimming bracket or the first chamber space, and motion transmission is achieved through the first transmission mechanism. The installation space of the horizontal adjustment mechanism and the movement and installation space of the dimming bracket are cleverly avoided, making full use of the concave cavity space of the lamp housing, optimizing the internal structure of the car lamp, and facilitating the design of the car lamp.

[0011] Furthermore, the first transmission mechanism includes a connecting part and a fixing part arranged in sequence along the vertical direction, the connecting part cooperates with the horizontal adjustment part to form a rotating shaft type rotating connection structure, and the axis of the rotating shaft type rotating connection structure coincides with the horizontal rotating shaft, the middle part of the fixing part protrudes toward the side away from the lamp housing to form a cross-shaped structure, and the inner side of the protrusion is fixedly connected to the output end of the horizontal adjustment mechanism.

[0012] The first transmission mechanism is caused to move synchronously with the output end of the horizontal adjustment mechanism through the fixing part, and then the horizontal adjustment point of the dimming bracket is driven to move synchronously through the connecting part, thereby realizing the transmission function of the first transmission mechanism and flexibly designing the horizontal adjustment mechanism at a position on the lamp housing away from the dimming bracket, so that the horizontal adjustment part moves with the movement of the output end of the horizontal adjustment mechanism, driving the dimming bracket to rotate around the vertical rotation axis.

[0013] In addition, the horizontal adjustment part serves as the connection part between the dimming bracket and the horizontal adjustment mechanism. By designing the two into a pivot-type rotating connection structure, and the axis of the pivot-type rotating connection structure coincides with the horizontal axis, the horizontal adjustment part can not only move by bearing the driving force of the connection part, but also rotate relative to the connection part. Then, when the dimming bracket rotates around the horizontal axis, the horizontal adjustment part rotates around the axis of the pivot-type rotating connection structure, without affecting the function of the vertical adjustment mechanism. The structural design is ingenious.

[0014] In addition, the "X"-shaped structure of the fixing portion greatly increases the adjustable range of the horizontal adjustment mechanism, while also optimizing the structural design of the headlight and increasing the stability of the adjustment system. Preferably, the horizontal adjustment mechanism uses a first screw mechanism to achieve manual adjustment.

[0015] Furthermore, the pivot-type rotating connection structure includes the horizontal adjustment part in the shape of an axis and the connecting part in the shape of a sleeve. The horizontal adjustment part is inserted into the sleeve hole of the connecting part and can rotate and slide freely. The axis of the horizontal adjustment part coincides with the horizontal rotating shaft. The connecting part is rotatably arranged on the top of the fixed part so that the axis of the sleeve hole of the connecting part remains colinear with the horizontal rotating shaft.

[0016] By protruding an axis-shaped horizontal adjustment part on one side of the dimming bracket, and cooperating with the sleeve-shaped connecting part to form a rotating shaft-type rotating connection structure, the axis of the horizontal adjustment part is arranged along the main length direction of the dimming bracket, and the axis coincides with the horizontal rotating shaft. At the same time, the horizontal adjustment part can rotate freely in the sleeve hole, so that the horizontal adjustment part can not only accept the driving force of the connecting part, but also serve as a part of the horizontal rotating shaft without affecting the vertical adjustment.

[0017] In addition, when the dimming bracket rotates around the vertical axis, the horizontal adjustment part can slide axially in the sleeve hole to compensate for the position difference caused by the circular motion of the horizontal adjustment part and the linear translation of the connecting part. At the same time, the connecting part can also rotate on the fixed part to keep the axis always coincident with the horizontal axis, so that the horizontal adjustment action of the horizontal adjustment mechanism is smooth and reliable, and there is no torsional stress inside the dimming bracket.

[0018] In the above-mentioned technical solution using a connecting part and a fixing part, an auxiliary cover plate for supporting the horizontal adjustment mechanism is provided on the inner side of the lamp housing, and a guide structure is also provided on the auxiliary cover plate. The first transmission mechanism also includes a guide part, and the guide part is used to cooperate with the guide structure to guide the movement of the first transmission mechanism along with the output end of the horizontal adjustment mechanism.

[0019] The guide part guides the translational follow-up of the first transmission mechanism to make the horizontal adjustment smoother. Since the horizontal adjustment mechanism usually adopts an adjusting screw structure and requires an auxiliary cover plate for support, it is convenient to add guide grooves, guide holes and other structures on the auxiliary cover plate to cooperate with the guide part to save materials and processes. The specific guide structure is groove-shaped, and the fixed part slides as a whole in the groove-shaped guide structure. A guide part composed of protrusions is provided on the fixed part, which is embedded in the guide structure to guide the sliding limit. In addition, the guide part can also be a slider, guide column or other structure that is compatible with the guide structure provided on the auxiliary cover plate.

[0020] Preferably, the guide portion is the lower horizontal side of the "X"-shaped structure of the fixing portion, which has a reasonable structural design, occupies a small space, and further optimizes the internal structural design of the headlight.

[0021] As another improvement of the vehicle light adjustment system of the present invention, the vertical adjustment mechanism includes a motor adjustment component, the main body of the motor adjustment component is arranged on the dimming bracket, and a second universal rotation connection structure is provided at the end of the telescopic shaft of the motor adjustment component, the rotation center of which is on the vertical rotation axis, and the second universal rotation connection structure.

[0022] By securing the motor adjustment assembly to the dimming bracket, the dimming bracket and the motor adjustment assembly rotate as a whole about the vertical axis, thereby making the electric adjustment design movable. This shortens the required length of the electric adjustment rod's extension and retraction, increasing stability. Furthermore, the end of the motor adjustment assembly's retractable shaft is universally pivoted on the vertical axis, serving as a support point for the vertical axis. This positional position ensures the vertical axis remains stationary during vertical adjustment, preventing interference between horizontal and vertical adjustments. After adjustment, the structural support remains stable, effectively reducing fluctuations in the low-beam cutoff line. Furthermore, when the motor adjustment assembly drives the dimming bracket to rotate about the horizontal axis, the second universal rotation connection structure slides along the vertical axis, compensating for the positional difference between the electric adjustment itself and the end of the adjustment rod caused by rotation.

[0023] Furthermore, the vertical adjustment mechanism also includes a second adjustment screw mechanism arranged on the lamp housing, and an adapter bracket is provided on the output end of the second adjustment screw mechanism. The adapter bracket supports the second universal rotation connection structure in the horizontal direction and is slidingly connected to the second universal rotation connection structure in the vertical direction.

[0024] The second adjustment screw mechanism is typically arranged horizontally. An adapter bracket is attached to its output end, providing a guide rail for the sliding of the second universal joint. This also allows for adjustment of the initial reference point at the telescopic end of the motor adjustment assembly, thereby manually adjusting the vertical axis to maintain a vertical position. Manual adjustment of the second adjustment screw mechanism is used for factory-installed or repair-grade light pattern calibration. Electric adjustment allows for on-the-fly adjustments to varying vehicle loads and road conditions.

[0025] As another improvement of the vehicle light adjustment system of the present invention, a rotation guide structure is provided between the dimming bracket and the lamp housing, and the rotation guide structure is used to limit the rotation direction of the dimming bracket to the horizontal direction or the vertical direction.

[0026] The rotational movement of the dimming bracket is guided by the rotation guide structure, limiting the dimming bracket to rotate only in the horizontal or vertical direction. Even if the light beam of the lamp group can only be adjusted left and right in the horizontal direction or up and down in the vertical direction, the stability of the adjustment system is increased, and deviations in the rotational adjustment movement caused by the need to make the dimming bracket space structure larger are avoided. Moreover, after adjustment, the rotation guide structure serves as a support point to support the dimming bracket so that it can maintain a stable adjustment position, significantly improving the stability of the headlights.

[0027] In the above-mentioned technical solution adopting a rotation guide structure, a horizontal rotation guide structure is arranged between the dimming bracket and the lamp housing, and the horizontal rotation guide structure is used to limit the rotation direction to the horizontal direction when the dimming bracket rotates around the vertical rotation axis. The horizontal rotation guide structure includes a first sliding shaft arranged on one side of the dimming bracket and a fixed horizontal groove adapted to the first sliding shaft, the axis of the first sliding shaft coincides with the horizontal rotation axis, the first sliding shaft extends into the fixed horizontal groove, and a gap is arranged between the first sliding shaft and the bottom of the fixed horizontal groove.

[0028] The fixed horizontal groove is used to limit the movement of the first sliding shaft provided on the dimming bracket during the adjustment process. Even if the first sliding shaft slides horizontally in the fixed horizontal groove while the dimming bracket rotates around the vertical rotation axis, and rotates around its own axis in the fixed horizontal groove while the dimming bracket rotates around the horizontal rotation axis, the fixed horizontal groove limits the up and down movement of the first sliding shaft, so that when the dimming bracket rotates around the vertical rotation axis, the rotation direction can only be in the horizontal direction, thereby increasing the stability of the adjustment system.

[0029] Preferably, the fixed horizontal groove is provided on the inner sidewall of the lamp housing, and the first sliding shaft and the shaft-shaped horizontal adjustment portion are arranged on either side of the first universal rotation connection structure, with their axes passing through the rotation center of the first universal rotation connection structure. This ensures a rational structural design of the entire horizontal adjustment mechanism, strong stability, and enhanced stability during the adjustment process.

[0030] In the above-mentioned technical solution adopting a rotary guide structure, a vertical rotary guide structure is arranged between the dimming bracket and the lamp housing, and the vertical rotary guide structure includes a second sliding shaft arranged at the bottom of the dimming bracket and a fixed vertical groove adapted to the second sliding shaft, the axis of the second sliding shaft coincides with the vertical rotating shaft, the second sliding shaft extends into the fixed vertical groove, and a gap is arranged between the end of the second sliding shaft and the bottom of the fixed vertical groove.

[0031] The fixed vertical slot limits the movement of the second sliding shaft provided on the dimming bracket during the adjustment process, so that the second sliding shaft slides in the fixed vertical slot while the dimming bracket rotates around the horizontal axis, and rotates around its own axis in the fixed vertical slot while rotating around the vertical axis. The fixed vertical slot limits the left and right movement of the second sliding shaft, so that when the dimming bracket rotates around the horizontal axis, the rotation direction can only be along the vertical direction, thereby increasing the stability of the adjustment system. It should be noted that the headlights of general vehicles are only adjusted in the vertical direction during normal use to adjust the angle of the light speed and adapt to different road inclinations and loads. Therefore, before leaving the factory, the second sliding shaft is first adjusted vertically, and then horizontal adjustment is performed to adjust the light beam of the lamp group to the standard value. Horizontal adjustment is not required in the future unless the vehicle is returned to the factory or professionally repaired.

[0032] In summary, by adopting the above-mentioned headlight adjustment system, the position of the adjustment mechanism can be adjusted according to the actual environmental requirements, thereby reasonably optimizing the headlight space design, and increasing the adjustable range of the adjustment mechanism, improving the stability of the adjustment process and the illumination stability of the rear light group after adjustment.

DETAILED DESCRIPTION

[0049] The following further describes the specific embodiments of the present invention in conjunction with the accompanying drawings. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention.

[0050] Example 1

[0051] Figure 1-14 FIG. 1 shows a vehicle light adjustment system of the present invention. Figure 1-4 As shown, the vehicle light adjustment system includes a lamp housing 1 for being fixedly connected to the vehicle body, a dimming bracket 2 arranged in the concave cavity of the lamp housing 1, and an adjustment mechanism for adjusting the posture of the dimming bracket 2. The lamp group 3 is fixed on the dimming bracket 2. The adjustment mechanism includes a horizontal adjustment mechanism 4 for driving the dimming bracket 2 to rotate around the vertical rotation axis and a vertical adjustment mechanism 5 for driving the dimming bracket 2 to rotate around the horizontal rotation axis. In the concave cavity of the lamp housing 1, the area where the dimming bracket 2 and the lamp housing 1 are opposite to each other forms a first chamber space. The main body of the horizontal adjustment mechanism 4 or the vertical adjustment mechanism 5 is arranged on the outer side of the first chamber space, so that the output end of the horizontal adjustment mechanism 4 or the vertical adjustment mechanism 5 needs to cross a certain distance to drive the dimming bracket 2.

[0052] When in use, the horizontal adjustment mechanism 4 or the vertical adjustment mechanism 5 is set on the outside side of the first chamber space, that is, on the side of the dimming bracket 2, so that the driving force of the adjustment mechanism is transmitted to the dimming bracket 2 across a certain distance. There is no need to strictly arrange the adjustment mechanism in the first chamber space opposite the back side of the dimming bracket 2. The position arrangement is flexible and will not affect the adjustment action of the dimming bracket 2. The position of the adjustment mechanism can be set according to the actual environmental requirements, effectively solving the problem that conventional adjustment solutions cannot be arranged due to styling restrictions, optimizing the structural design of the car lamp, better meeting the car lamp styling, and also making the adjustment space of the adjustment mechanism larger and the adjustment stable.

[0053] A first universal rotating connection structure 6 is provided between the dimming bracket 2 and the lamp housing 1, so that the dimming bracket 2 can rotate freely around the rotation center of the first universal rotating connection structure 6. The horizontal adjustment mechanism 4 drives the dimming bracket 2 to rotate around the vertical rotation axis, and adjusts the illumination condition of the lamp group 3 in the horizontal direction. The vertical rotation axis is a vertical straight line passing through the rotation center of the first universal rotating connection structure 6. The vertical adjustment mechanism 5 drives the dimming bracket 2 to rotate around the horizontal rotation axis, and adjusts the illumination condition of the lamp group 3 in the vertical direction. The horizontal rotation axis is a horizontal straight line passing through the rotation center of the first universal rotating connection structure 6.

[0054] like Figure 3 As shown, the lamp housing 1 is a shell-like structure with a concave cavity. The lamp housing 1 and the lampshade cooperate to form a chamber for placing the lamp group 3. The lamp housing 1 is fixed to the vehicle body by screws and other fixings. The dimming bracket 2 is a long, uneven sheet-like structure with a certain degree of toughness. Generally, in order to reduce the weight of the dimming bracket 2 and maintain its strength, the dimming bracket 2 is designed as a supporting structure composed of a main bracket 201 and an outer bracket 202 fixedly connected. The main bracket 201 is used to connect with the adjustment mechanism to withstand the driving force. The outer bracket 202 is fixed to the main bracket 201 to support the lamp group 3. The two can be made of different materials, which saves cost and weight of the vehicle lamp and also facilitates the support and fixation of other components such as the lamp group 3.

[0055] In addition, if Figure 3 and Figure 5 As shown, the dimming bracket 2 is mounted on the side of the lamp housing 1 away from the vehicle body via a first universal rotation connection structure 6. This first universal rotation connection structure 6 utilizes a first ball head structure, with its fixing point located in the middle of the top edge of the dimming bracket 2 and at the horizontal center of the lamp assembly 3. To ensure that the fixing point of the first ball head structure is located at the center of the vehicle lamp, an inner bracket 44 is provided on the inner sidewall of the lamp housing 1 to securely support the first ball head structure. The lamp assembly 3 is also fixed to the top edge of the dimming bracket 2, and the light beam it emits passes through the lampshade, illuminating the road ahead of the vehicle.

[0056] During use, the first universal rotation connection structure 6, the horizontal adjustment mechanism 4, and the vertical adjustment mechanism 5 provide three support points for the mounting of the dimming bracket 2: the universal rotation point, the horizontal adjustment point, and the vertical adjustment point, thereby forming a triangular mounting structure. Typically, these three support points form a right triangle or a nearly right triangle-shaped support structure. Adjusting the position of the dimming bracket 2 is achieved by moving the horizontal adjustment point or the vertical adjustment point, thereby ensuring that the illumination range of the lamp assembly 3 is appropriately adjusted. The vertical adjustment mechanism 5 is used to drive the dimming bracket 2 to rotate about a horizontal axis passing through the rotation point of the first universal rotation connection structure 6, thereby adjusting the angle of the illumination beam of the lamp assembly 3 and changing the illumination height of the lamp assembly 3. The horizontal adjustment mechanism 4 is used to drive the dimming bracket 2 to rotate about a vertical axis passing through the rotation point of the first universal rotation connection structure 6, thereby adjusting the left and right angles of the illumination of the lamp assembly 3 and changing the illumination width of the two lamp assembly 3. Typically, the horizontal adjustment point is located on the horizontal axis, and the vertical adjustment point is located on the vertical axis.

[0057] In order to optimize the layout space of the internal adjustment mechanism of the headlight, such as Figure 6 As shown, the horizontal adjustment mechanism 4 is arranged on one side of the dimming bracket 2, and a first transmission mechanism 41 is arranged between the output end of the horizontal adjustment mechanism 4 and the horizontal adjustment part 21 corresponding to the dimming bracket 2. The first transmission mechanism 41 is used to transmit the horizontal movement of the output end of the horizontal adjustment mechanism 4 to the horizontal adjustment part 21 across a certain distance, driving the dimming bracket 2 to rotate around the vertical axis.

[0058] The first transmission mechanism 41 is used to transmit the driving force of the horizontal adjustment mechanism 4 to the dimming bracket 2 across a certain distance, and transfer the force point of the dimming bracket 2 to the empty space at a certain distance on one side of the interior of the headlight, which is convenient for the arrangement of the horizontal adjustment mechanism 4 and has a large adjustable space.

[0059] Optional, such as Figure 7 and Figure 8 As shown, the horizontal adjustment mechanism 4 utilizes a first adjustment screw mechanism 42 for manual adjustment, located in the spare space inside the left headlight of the dimming bracket 2. The first adjustment screw mechanism 42 comprises a vertically arranged first screw 421, a horizontally arranged second screw 422, and a screw connecting sleeve 423 disposed externally of the second screw 422. The first screw 421 is sealed and extends through the lamp housing 1. It can be twisted from the outside, driving the screw connecting sleeve 423 to rotate, thereby driving the second screw 422 inside. The inner end of the second screw 422 is fixedly connected to the fixing portion 412, enabling manual adjustment. To allow the screw connecting sleeve 423 to be rotated and installed, an auxiliary cover 43 is provided on the inner side of the lamp housing 1.

[0060] like Figure 7 and Figure 9As shown, the first transmission mechanism 41 includes a connecting portion 411 that is rotatably connected to the dimming bracket 2 and a fixing portion 412 that is fixedly connected to the output end of the horizontal adjustment mechanism 4. The connecting portion 411 is sleeve-shaped and has a through hole that mates with the dimming bracket 2. The fixing portion 412 protrudes away from the lamp housing 1 in a "F" shape to reserve sufficient adjustable space for the first adjustment screw mechanism 42.

[0061] Optionally, the first transmission mechanism 41 further includes a guide portion 413, which is used to guide the first transmission mechanism 41 to move along with the output end of the horizontal adjustment mechanism 4, so that the horizontal adjustment is more stable and reliable.

[0062] like Figure 8 As shown, the guide portion 413 is composed of protrusions arranged on the sides of the two ends of the X-shaped structure of the fixing portion 412, and the corresponding Figure 10 As shown, the guide structure on the auxiliary cover plate 43 is a guide groove 431 , and the fixing portion 412 is entirely wrapped in the guide groove 431 , allowing the guide portion 413 to guide the entire fixing portion 412 to slide.

[0063] Optionally, the matching structure of the guide portion 413 and the auxiliary cover plate 43 can be used in other ways. The guide portion 413 can be a guide column structure arranged on the fixed portion 412, which is movably inserted into the guide hole at the corresponding position of the auxiliary cover plate 43, or it can be a slider structure, which is embedded in the guide rail at the corresponding position of the auxiliary cover plate 43 and slides.

[0064] like Figure 9 As shown, the top of one side of the main bracket 201 of the dimming bracket 2 protrudes and forms an axis-shaped horizontal adjustment part 21 at the end. The horizontal adjustment part 21 is inserted into the sleeve hole of the connecting part 411 and rotates and slides freely, and the axis of the horizontal adjustment part 21 coincides with the horizontal rotation axis. The connecting part 411 is rotatably fixed on the first transmission mechanism 41 so that the axis of the sleeve hole of the connecting part 411 remains through the rotation center of the first universal rotating connection structure 6.

[0065] like Figure 11 As shown, the vertical adjustment mechanism 5 includes a motor adjustment assembly 51. The main body of the motor adjustment assembly 51 is mounted on the dimming bracket 2. A second universal rotation connection structure 52 is provided at the end of the telescopic shaft of the motor adjustment assembly 51. The second universal rotation connection structure 52 is slidably mounted on the vertical axis, causing the dimming bracket 2 and the motor adjustment assembly 51 to rotate about the vertical axis as a whole. When the motor adjustment assembly 51 drives the dimming bracket 2 to rotate about the horizontal axis, the second universal rotation connection structure 52 slides along the vertical axis. For vertical adjustment, the motor adjustment assembly 51 is designed to be mounted on the main bracket 201. The motor moves up and down with the main bracket 201, shortening the telescopic rod length of the electric adjuster and increasing stability. While the vehicle is in motion, the beam angle can be electrically adjusted from within the cab.

[0066] Optionally, the vertical adjustment mechanism 5 also includes a second adjustment screw mechanism 53 disposed on the lamp housing 1. An adapter bracket 531 is disposed at the output end of the second adjustment screw mechanism 53. The adapter bracket 531 is vertically slidably connected to the second universal rotation connection structure 52. The second universal rotation connection structure 52 is secured to the vertical shaft via the adapter bracket 531. The adapter bracket 531 can be slidably mounted on a horizontal support plate of the inner bracket 44, thereby enabling the second adjustment screw mechanism 53 to adjust the position of the second universal rotation connection structure 52. When the vehicle leaves the factory, it is adjusted to be directly below the first universal rotation connection structure 6, thereby maintaining the vertical shaft in a vertical position.

[0067] In order to keep the rotation direction of the dimming bracket 2 horizontal or vertical, a rotation guide structure is provided between the dimming bracket 2 and the lamp housing 1 , and the rotation guide structure is used to limit the rotation direction of the dimming bracket 2 to the horizontal direction or the vertical direction.

[0068] In the horizontal direction, Figure 1 、 Figure 12 and Figure 13 As shown, a horizontal rotation guide structure 7 is provided between the dimming bracket 2 and the lamp housing 1. The horizontal rotation guide structure 7 is used to limit the rotation direction of the dimming bracket 2 to the horizontal direction when the dimming bracket 2 rotates around the vertical rotation axis. The horizontal rotation guide structure 7 includes a first slide shaft 71 provided on one side of the dimming bracket 2 and a fixed horizontal slot 72 adapted to the first slide shaft 71. The axis of the first slide shaft 71 coincides with the horizontal rotation axis. The first slide shaft 71 extends into the fixed horizontal slot 72 and slides horizontally within the fixed horizontal slot 72 as the dimming bracket 2 rotates around the vertical rotation axis. As the dimming bracket 2 rotates around the horizontal rotation axis, the first slide shaft 71 rotates around its own axis within the fixed horizontal slot 72. The fixed horizontal slot 72 limits the up and down movement of the first slide shaft 71. Optionally, the fixed horizontal slot 72 is provided on the lamp housing 1.

[0069] The first sliding shaft 71 and the shaft-shaped horizontal adjustment portion 21 are distributed on both sides of the first universal rotation connection structure 6, and the axes pass through the rotation center of the first universal rotation connection structure 6. This makes the structural design of the entire horizontal adjustment mechanism 4 reasonable and stable, and increases the stability of the adjustment process.

[0070] In the vertical direction, Figure 11 and Figure 14As shown, a vertical rotation guide structure 8 is provided between the dimming bracket 2 and the lamp housing 1. The vertical rotation guide structure 8 includes a second slide shaft 81 provided at the bottom of the dimming bracket 2 and a fixed vertical slot 82 adapted to the second slide shaft 81. The axis of the second slide shaft 81 coincides with the vertical rotation axis. The second slide shaft 81 extends into the fixed vertical slot 82 and slides within the fixed vertical slot 82 as the dimming bracket 2 rotates around the horizontal rotation axis. As the dimming bracket 2 rotates around the vertical rotation axis, the second slide shaft 81 rotates around its own axis within the fixed vertical slot 82. The fixed vertical slot 82 limits the left and right movement of the second slide shaft 81. Optionally, the fixed vertical slot 82 is provided at the bottom of the inner bracket 44.

[0071] The fixed vertical slot 82 limits the movement of the second sliding shaft 81 provided on the dimming bracket 2 during the adjustment process, so that when the dimming bracket 2 rotates around the horizontal axis, the rotation direction can only be along the vertical direction, thereby increasing the stability of the adjustment system.

[0072] The final design of the structure of the main support 201 is as follows Figure 14 shown.
