Detailed Implementation

[0044] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0045] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0046] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0047] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0048] With the development of intelligent vehicles, the functions and technologies of automotive lights are constantly evolving, gradually transforming from traditional lighting tools into intelligent vision systems. In particular, the widespread application of digital light processing technology has enabled automotive lights to go beyond simply providing basic lighting functions, achieving more complex and diverse light control and display effects.

[0049] Digital Light Processing (DLP) technology uses microlens arrays and digital signal processing to achieve high-precision light control. This technology allows the headlights to automatically adjust the shape, intensity, and direction of the beam according to different driving environments and needs. For example, when driving at night, the DLP headlights can intelligently adjust the beam based on the distance and position of vehicles ahead, avoiding glare for other drivers while ensuring the driver has optimal visibility. This flexibility not only improves driving safety but also provides more reliable visual support for intelligent driving.

[0050] However, the current process of adjusting the focus of the headlights (7) largely relies on manual operation, which is not only inefficient but also makes it difficult to guarantee the consistency and accuracy of the adjustment. During manual adjustment, workers need to judge and adjust the focus of the headlights (7) based on experience, which is not only time-consuming but also easily affected by human factors, resulting in unstable focusing effects.

[0051] Please see Figure 1 The following describes the headlight focusing adjustment system 7 provided in the embodiments of this application. The headlight focusing adjustment system 7 includes:

[0052] Feeding assembly 1; Feeding assembly 1 is used to confine the headlight 7 to the focus adjustment station;

[0053] Focusing assembly 2; Focusing assembly 2 is used to adjust the focal length of the vehicle headlight 7 located at the focal length adjustment station to the target focal length;

[0054] Fixing component 3; Fixing component 3 is used to fix the focal length of the headlight 7 at the target focal length.

[0055] In this embodiment, the main function of the loading component 1 is to confine the vehicle lamp 7 to the focus adjustment station so that subsequent focusing operations can be performed accurately. Specifically, the loading component 1 can serve only to fix the vehicle lamp 7, or it can simultaneously move and adjust the vehicle lamp 7. The loading component 1 can adopt various structures. For example, the loading component 1 can be a mechanical clamp, using clamps of various shapes and sizes to hold the vehicle lamp 7 and ensure that it is stably placed on the focus adjustment station; the loading component 1 can also be a pneumatic or hydraulic drive device, using air pressure or hydraulic pressure to drive the clamp to open and close, realizing rapid loading and positioning of the vehicle lamp 7; the loading component 1 can also be a conveyor belt or a robotic arm, used to move the vehicle lamp 7 from the storage position to the focus adjustment station.

[0056] The focusing assembly 2 is located at the focus adjustment station and is used to precisely adjust the focus of the headlight 7 until the target focus is achieved. The target focus refers to the ideal focus that the headlight 7 is expected to achieve after focusing. The focusing assembly 2 can be a motor rotation drive system, using a stepper motor or servo motor to drive the lens 72 of the headlight 7 to rotate, thus achieving fine-tuning of the focus. Alternatively, the focusing assembly 2 can be a moving mechanism, moving the headlight 7 to the lens 72 or reflector to achieve fine-tuning of the focus. Furthermore, the focusing assembly 2 can also work in conjunction with sensors and a control system. The sensors detect and provide feedback to the focusing structure, and the control system then controls the precise focusing of the focusing assembly 2.

[0057] Once the focus of the headlight 7 is adjusted to the target focus, the fixing component 3 will function to fix the focus in this position to prevent changes during subsequent operation or transportation. The fixing component 3 can be a mechanical fastening mechanism, such as screw locking, snap locking, etc.; the fixing component 3 can also be fixed by adhesive.

[0058] In this embodiment, the headlight 7 focusing adjustment system can be used to place the headlight 7 onto the loading component 1 manually or automatically. The loading component 1 is used to fix or move the headlight 7 to the focus adjustment position. The focusing component 2 performs a focusing operation on the headlight 7 so that the focus of the headlight 7 reaches the target focus. Once the focus is adjusted to the target value, the fixing component 3 fixes the focus of the headlight 7 at the target focus, thereby completing the focusing of the headlight 7.

[0059] In this embodiment, the headlight 7 focusing adjustment system is directly fixed by the fixing component 3 after focusing by the focusing component 2. Compared with manual focusing, it can effectively improve efficiency, adjustment accuracy and stability, reduce human error to a large extent, and is also easier to operate.

[0060] Please refer to the following: Figures 2 to 4 In some embodiments of this application, the feeding component 1 includes a plug-in 12 and a first clamping mechanism 11. The plug-in 12 is used to plug into the vehicle light 7 and is arranged along a first direction. The first clamping mechanism 11 is used to clamp the vehicle light 7 along the first direction.

[0061] In this embodiment, the loading assembly 1 includes a connector 12 and a first clamping mechanism 11. The connector 12 acts as a bridge for positioning the vehicle lamp 7 and the loading assembly 1. By interlocking with a specific part of the vehicle lamp 7, it facilitates rapid positioning of the loading assembly 1 and the vehicle lamp 7, preventing the vehicle lamp 7 from shifting during clamping and fixing. The specific structure of the connector 12 can be designed according to a specific part of the vehicle lamp 7. Typically, the mounting hole, slot, or protrusion of the vehicle lamp 7 can be selected as the specific part. For example, if the specific part is a mounting hole or positioning hole of the vehicle lamp 7, the connector 12 can be a rod-shaped member. The positioning of the vehicle lamp 7 is achieved by inserting the rod-shaped member into the mounting hole or positioning hole. Alternatively, if the specific part is a protrusion of the vehicle lamp 7, the connector 12 can have a structure with a recessed hole. The positioning of the vehicle lamp 7 is achieved by the interlocking of the protrusion and the recessed hole.

[0062] Set plugin 12 along the first direction, which is... Figure 2 The first direction is A, therefore, the headlight 7 and the connector 12 are interlocked and positioned along the first direction. The first direction varies depending on the specific part of the headlight 7 selected. For example, if the mounting hole or positioning hole of the headlight 7 is selected as the specific part, then the axis of the mounting hole or positioning hole is the first direction. This first direction includes two opposing directions, positive and negative.

[0063] The headlight 7 is clamped and fixed by the first clamping mechanism 11, which can be pneumatic, electric, or mechanical. The pneumatic clamping mechanism is driven by air pressure to open and close; the electric clamping mechanism is driven by a motor, which has higher precision and controllability; the mechanical clamping mechanism can use mechanical principles such as springs and levers to achieve a simple clamping function.

[0064] In this embodiment, the first clamping mechanism 11 clamps the vehicle light 7 along the first direction, and the first direction is set along the first direction for the plug-in 12. Therefore, during the clamping process, the first clamping mechanism 11 can realize the insertion and positioning of the plug-in 12 and the vehicle light 7. At the same time, the plug-in 12 can also guide the clamping of the first clamping mechanism 11, thereby ensuring that the vehicle light 7 will not shift during the clamping process.

[0065] During operation, the vehicle light 7 can be placed on the feeding assembly 1 manually or by automated machinery. Make sure that the specific part of the vehicle light 7 is aligned with the plug-in 12 and inserted. The first clamping mechanism 11 clamps the vehicle light 7 along the first direction to achieve stable fixation of the vehicle light 7.

[0066] Please refer to the following: Figure 2 and Figure 3 In some embodiments of this application, the plug-in 12 includes a plug rod 121 for plugging into the first hole of the vehicle light 7.

[0067] The plug-in 12 is a key component in the headlight 7 focusing adjustment system used to connect with the headlight 7. It achieves positioning of the headlight 7 and the feeding assembly 1 by plugging into a specific part of the headlight 7. In this embodiment, the plug-in 12 is a connector rod 121, the shape of which is determined by the shape of the first hole on the headlight 7. The first hole can be a mounting hole or a positioning hole for the headlight 7. The connector rod 121 can be mounted on the bracket of the feeding assembly 1 to ensure its load-bearing performance.

[0068] The number of connector rods 121 can be one or more, and the number of first holes in the corresponding vehicle light 7 also needs to be one or more, with both numbers being consistent. The multiple connector rods 121 and multiple first holes interlock to prevent rotation that might occur when a single connector rod 121 is interlocked with a single first hole. For example, Figure 2 The embodiment shown employs a method of connecting two plug rods 121 and two first holes.

[0069] Please refer to the following: Figure 4 In some embodiments of this application, the first clamping mechanism 11 includes a first clamping part 111 and a second clamping part 112 that can be close to each other. The first clamping part 111 is used to abut against the first side of the mounting part 71 of the vehicle lamp 7, and the second clamping part 112 is used to abut against the second side of the vehicle lamp 7. The first side is the opposite side of the second side.

[0070] The first clamping mechanism 11 is used to clamp and fix the vehicle lamp 7 to facilitate focusing adjustment of the vehicle lamp 7. The first clamping mechanism 11 clamps the vehicle lamp 7 through a first clamping part 111 and a second clamping part 112 that can be brought close to each other. The first clamping part 111 abuts against a first side of the vehicle lamp 7 mounting part 71, and the second clamping part 112 abuts against a second side of the vehicle lamp 7 mounting part 71. The first side is opposite to the second side, meaning the first clamping part 111 and the second clamping part 112 clamp the vehicle lamp 7 mounting part 71 on both sides. The vehicle lamp 7 mounting part 71 is the part where the vehicle lamp 7 is installed and fixed. It has relatively high strength and can support and stabilize the entire vehicle lamp 7. By using the first clamping part 111 and the second clamping part 112 to clamp the vehicle lamp 7 mounting part 71, the stability of the vehicle lamp 7 can be ensured.

[0071] The first clamping part 111 and the second clamping part 112 can be driven by pneumatic, electric or other means, so that they can approach each other to achieve clamping. Figure 4 In the illustrated embodiment, a first clamping mechanism 11 is provided on both sides of the headlight 7. After the headlight 7 is placed, the first clamping part 111 abuts against the upper and lower mounting holes of the headlight 7 mounting part 71, while the second clamping part 112 abuts against the middle of the opposite side of the mounting part 71. The second clamping part 112 is connected to a first cylinder 113 via a lever structure. The first cylinder 113 drives the movement of the second clamping part 112 to bring it closer to the first clamping part 111, thereby clamping the headlight 7. Furthermore, if the headlight 7 has a fixed circuit interface, a corresponding module can be installed on the first clamping mechanism 11 and plugged into it, further ensuring the accuracy of the headlight 7's position.

[0072] Please refer to the following: Figure 5 and Figure 6 In some embodiments of this application, the feeding assembly 1 further includes an abutting mechanism 13, which is used to abut the vehicle light 7 in a second direction, the second direction being perpendicular to the first direction.

[0073] Because there will be a certain gap when the plug-in 12 is connected to the headlight 7, although the plug-in 12 can be kept relatively stable, there is still some wobbling in the second direction perpendicular to the first direction. Figure 5 As shown, the second direction is direction B in the figure, and the first direction is direction A. Direction A is perpendicular to direction B. Therefore, in this embodiment, the feeding assembly 1 also includes an abutting mechanism 13, which is used to abut the vehicle lamp 7 along the second direction, which is perpendicular to the first direction. The first direction is the insertion direction of the plug-in 12, that is, the abutting mechanism 13 can abut the vehicle lamp 7 in a direction perpendicular to the insertion direction of the plug-in 12, thereby reducing the impact on the gaps that may exist when the plug-in 12 and the vehicle lamp 7 are inserted, thus more accurately positioning the vehicle lamp 7, and ensuring that the first clamping mechanism 11 accurately clamps the vehicle lamp 7. The second direction here includes two opposing positive and negative directions.

[0074] The contact mechanism 13 can use an electric or pneumatic telescopic structure to contact the vehicle headlight 7. Figure 6 In the illustrated embodiment, the abutting mechanism 13 includes a second cylinder 132 and an abutting rod 131 driven by the second cylinder 132. The second cylinder 132 can drive the abutting rod 131 to abut against one side of the vehicle headlight 7. The mounting location of the abutting rod 131 is provided with multiple selectable mounting holes, so that the abutting rod 131 can be installed in different mounting holes to adjust the position of the abutting rod 131.

[0075] Please refer to the following:Figure 7 In some embodiments of this application, the feeding assembly 1 further includes a first adjustment assembly. The first adjustment assembly includes a first adjustment mechanism 141, a second adjustment mechanism 142, and a third adjustment mechanism 143 connected to each other. The first adjustment mechanism 141 is used to adjust the position of the vehicle lamp 7 in a third direction, the second adjustment mechanism 142 is used to adjust the position of the vehicle lamp 7 in a fourth direction, and the third adjustment mechanism 143 is used to adjust the position of the vehicle lamp 7 in a fifth direction. The third direction is perpendicular to the fourth direction, the fourth direction is perpendicular to the fifth direction, and the fifth direction is perpendicular to the third direction.

[0076] As mentioned earlier, the loading assembly 1 can serve only to fix the headlight 7, or it can simultaneously move and adjust the headlight 7. In this embodiment, the loading assembly 1 also includes a first adjustment assembly, which can move and adjust the headlight 7, thereby accurately moving the headlight 7 to the focus adjustment position. The first adjustment assembly includes a first adjustment mechanism 141, a second adjustment mechanism 142, and a third adjustment mechanism 143. These three adjustment mechanisms are interconnected and together constitute the core of the first adjustment assembly. The first adjustment mechanism 141 is used to adjust the position of the headlight 7 in a third direction, the second adjustment mechanism 142 is used to adjust the position of the headlight 7 in a fourth direction, and the third adjustment mechanism 143 is used to adjust the position of the headlight 7 in a fifth direction. The third direction is perpendicular to the fourth direction, the fourth direction is perpendicular to the fifth direction, and the fifth direction is perpendicular to the third direction. Thus, the third direction, the fourth direction, and the fifth direction actually form a spatial rectangular coordinate system, where the third direction, the fourth direction, and the fifth direction correspond to one of the X-axis, Y-axis, and Z-axis, respectively. The first adjustment mechanism 141, the second adjustment mechanism 142, and the third adjustment mechanism 143 can employ pneumatic or electric drive components in conjunction with sliding rails or similar structures, enabling the first adjustment mechanism 141 to move along a third direction, the second adjustment mechanism 142 to move along a fourth direction, and the third adjustment mechanism 143 to move along a fifth direction, thereby achieving adjustment of the vehicle headlight 7 in three-dimensional space. The third, fourth, and fifth directions each contain two opposing positive and negative directions.

[0077] like Figure 7 In the embodiment shown, the third direction is the Y-axis, the fourth direction is the X-axis, and the fifth direction is the Z-axis. The plug-in 12 and the first clamping mechanism 11 are set on the first adjustment assembly. The three adjustment mechanisms in the first adjustment assembly are respectively responsible for one X-axis, one Y-axis, and one Z-axis. Specifically, the first adjustment mechanism 141 can move and adjust the headlight 7 along the Y-axis, the second adjustment mechanism 142 can move and adjust the headlight 7 along the X-axis, and the third adjustment mechanism 143 can move and adjust the headlight 7 along the Z-axis.

[0078] Please refer to the following: Figure 8 and Figure 9In some embodiments of this application, the focusing assembly 2 includes a second clamping mechanism 21 and a first rotating mechanism 22. The second clamping mechanism 21 is used to clamp the lens 72 of the vehicle lamp 7. The second clamping mechanism 21 is connected to the first rotating mechanism 22. The first rotating mechanism 22 is used to drive the second clamping mechanism 21 to rotate, so as to drive the lens 72 of the vehicle lamp 7 to rotate and focus.

[0079] The focusing assembly 2 is used to adjust the focal length of the headlight 7 to the target focal length. This embodiment includes a second clamping mechanism 21 and a first rotating mechanism 22. The focusing principle of this embodiment is to adjust the focal length of the headlight 7 by rotating the lens 72 of the headlight 7. The second clamping mechanism 21 is used to clamp the lens 72 of the headlight 7, ensuring that the lens 72 stably follows the movement of the first rotating mechanism 22 when adjusting the focal length. The second clamping mechanism 21 can adopt various clamping components such as jaws or chucks. The first rotating mechanism 22 is connected to the second clamping mechanism 21 and is used to drive the second clamping mechanism 21 to rotate, thereby driving the lens 72 of the headlight 7 to rotate to achieve focusing. The first rotating mechanism 22 can adopt a stepper motor, servo motor, or other driving components, and can drive the second clamping mechanism 21 to rotate via a synchronous belt, gears, etc.

[0080] When adjusting the focal length, the main body of the headlight 7 is fixed by the feeding assembly 1, while the second clamping mechanism 21 clamps the lens 72 of the headlight 7. The first rotating mechanism 22 can drive the second clamping mechanism 21 to rotate, thereby driving the lens 72 to rotate relative to the main body of the headlight 7, thus realizing the adjustment of the focal length of the headlight 7.

[0081] In such Figure 9 In the embodiment shown, the second clamping mechanism 21 includes a clamping cylinder 211 arranged vertically to drive the upper and lower grippers 212 to clamp the lens 72 of the vehicle light 7. In order to protect the vehicle light 7, soft rubber is also provided at the contact part between the grippers 212 and the vehicle light 7.

[0082] Please refer to the following: Figure 10 and Figure 11 In some embodiments of this application, the fixing component 3 includes a dispensing mechanism 31 and a curing mechanism 32. The dispensing mechanism 31 is used to dispense adhesive to the lens 72 of the vehicle light 7, and the curing mechanism 32 is used to cure the adhesive.

[0083] In this embodiment, the fixing component 3 uses adhesive dispensing to fix the focal length of the headlight 7. The fixing component 3 mainly consists of two key parts: an adhesive dispensing mechanism 31 and a curing mechanism 32. The main function of the adhesive dispensing mechanism 31 is to dispense adhesive onto the headlight 7. After the headlight 7 is focused, the adhesive dispensing mechanism 31 can accurately apply the adhesive to the area where the headlight 7 lens 72 needs to be fixed, thereby fixing the lens 72 and thus fixing the focal length. The main function of the curing mechanism 32 is to cure the adhesive, that is, to allow the adhesive applied to the headlight 7 lens 72 to dry and harden quickly, thereby fixing the lens 72 and maintaining the stability of the focal length. The adhesive dispensing mechanism 31 can be a pneumatic dispensing machine, an electric precision dispensing machine, etc., while the curing mechanism 32 can be set accordingly for different adhesives. For example, for thermosetting adhesives, the curing mechanism 32 can use a thermosetting device to accelerate the chemical reaction of the adhesive by heating, so that it cures quickly. For light-curing adhesives, the curing unit 32 can be a UV curing device. The UV curing device emits ultraviolet light, which, when irradiated, causes a photochemical reaction in the chemical substances in the adhesive, thus achieving rapid curing. For example... Figure 11 In the embodiment shown, the curing mechanism 32 uses a UV curing device.

[0084] Please refer to the following: Figure 10 , Figure 12 and Figure 13 In some embodiments of this application, the fixing component 3 and the focusing component 2 are located on different sides of the feeding component 1; the feeding component 1 also includes a second adjustment component, which includes a flipping mechanism 151 and a second rotating mechanism 152. The flipping mechanism 151 is used to flip the lens 72 of the vehicle lamp 7 to the side where the fixing component 3 is located, and the second rotating mechanism 152 is used to drive the vehicle lamp 7 to rotate along its axis so that the lens 72 of the vehicle lamp 7 changes its orientation toward the area of ​​the dispensing mechanism 31 in the circumferential direction.

[0085] The headlight 7 is mounted on the feeding assembly 1. Therefore, the side of the fixing assembly 3 and the focusing assembly 2 relative to the feeding assembly 1 is the same as the side of the fixing assembly 3 and the focusing assembly 2 relative to the headlight 7. In this embodiment, the fixing assembly 3 and the focusing assembly 2 are located on different sides of the feeding assembly 1. This prevents interference between the positions of the fixing assembly 3 and the focusing assembly 2, and allows both to have relatively ample space for arrangement.

[0086] However, since the fixing component 3 and the focusing component 2 are located on different sides of the feeding component 1, the headlight 7 needs to be readjusted to the side of the fixing component 3 after the focusing component 2 is used to adjust the focus in order to fix the focus. Therefore, the feeding component 1 in this embodiment also includes a second adjustment component, which includes a flipping mechanism 151 and a second rotating mechanism 152. The flipping mechanism 151 can flip the lens 72 of the headlight 7 from the side of the focusing component 2 to the side of the fixing component 3 after focusing is completed, so as to perform subsequent fixing operations. The flipping mechanism 151 can use a rotary motor, cylinder, or other driving device, and realize the flipping of the lens 72 through a transmission mechanism such as a linkage or gear. The second rotating mechanism 152 is used to drive the headlight 7 to rotate along its axis, so that the lens 72 of the headlight 7 changes its orientation towards the area of ​​the dispensing mechanism 31 in the circumferential direction, thereby realizing the dispensing of adhesive on the lens 72 in the circumferential direction and ensuring the stability of the focal length of the lens 72. The second rotating mechanism 152 can be driven by a rotary motor, stepper motor or other drive device, and the rotation of the vehicle lamp 7 can be achieved through a transmission mechanism such as bearings and couplings.

[0087] In addition to adjusting the headlight 7 using the second adjustment component, the dispensing mechanism 31 itself can also be adjusted. For example, the dispensing mechanism 31 can be mounted on a slide table, and the distance between the dispensing mechanism 31 and the headlight 7 can be adjusted by the slide table, thereby further ensuring the accuracy of dispensing.

[0088] In some other embodiments, the fixing component 3 and the focusing component 2 are located on the same side of the feeding component 1. Although this makes the arrangement of the fixing component 3 and the focusing component 2 more compact, it is possible to fix the lens 72 of the vehicle light 7 using the fixing component 3 without setting up the flipping mechanism 151 to flip the vehicle light 7, thereby fixing the focal length of the vehicle light 7.

[0089] Please refer to the following: Figure 1 In some embodiments of this application, the headlight focusing adjustment system further includes:

[0090] Imaging light screen 4; Imaging light screen 4 is used to receive and display the image formed by the light emitted by the vehicle headlights 7;

[0091] Image acquisition component 5; Image acquisition component 5 is used to acquire the image formed on the imaging light screen 4;

[0092] Image processing component; The image processing component is used to analyze the images acquired by image acquisition component 5;

[0093] The focusing component 2 is used to adjust the focal length of the headlight 7 based on the analysis results of the image processing component.

[0094] In this embodiment, the main function of the imaging light curtain 4 is to receive and display the image formed by the light emitted by the vehicle headlight 7, so that the image acquisition component 5 can acquire the image. The shape and size of the imaging light curtain 4 can be customized according to the type of vehicle headlight 7 and usage requirements, such as a planar, curved, or specific angle design. To improve the clarity and contrast of the image, the surface of the imaging light curtain 4 can be coated with a special reflective or scattering coating, and different coatings can be selected according to the different vehicle headlights 7.

[0095] The image acquisition component 5 is used to acquire the image formed on the imaging light screen 4 and transmit it to the image processing component. The image acquisition component 5 may include a camera, an image sensor, etc., such as a CCD sensor that converts the captured light image into a digital signal.

[0096] The image processing component analyzes the images acquired by the image acquisition component 5. This component can be an image processor capable of real-time processing and analysis of the acquired images. The image processing component may also include a user interface for displaying analysis results and allowing manual adjustments. Based on the analysis results from the image processing component, the focusing component 2 automatically adjusts the focal length of the headlight 7 to ensure precise focusing of the light. Furthermore, a lux meter can be installed at the location of the shaped light curtain to detect the illuminance of the headlight 7.

[0097] Please refer to the following: Figure 1 In some embodiments of this application, the headlight 7 focusing adjustment system further includes a teleconverter 6, which is used to shorten the optical path of the headlight 7.

[0098] Since the illumination distance of the vehicle headlight 7 is typically long, and the testing system's venue or space usually cannot directly meet the illumination distance requirements of the vehicle headlight 7, in this embodiment, the vehicle headlight 7 focusing adjustment system also includes a teleconverter 6. The teleconverter 6 can shorten the optical path of the vehicle headlight 7. This means that it can focus a beam of light that originally required a long distance to form a focus within a shorter distance. This is very useful for vehicle design, especially for those models with limited space, as it allows for effective lighting testing within a confined space. The teleconverter 6 is positioned corresponding to the lens 72 of the vehicle headlight 7, for example, it can be positioned on the focusing assembly 2. The teleconverter 6 can typically be a repeater mirror, utilizing the teleconverter's teleconverting effect to achieve teleconverting of the light beam from the vehicle headlight 7. Figure 1 Taking the Chinese embodiment as an example, the relay mirror in this embodiment can shrink the image from 10m to 0.9m and ensure that the image is distortion-free.

[0099] Please refer to the following: Figure 14In some embodiments of this application, the headlight 7 focusing adjustment system further includes a third adjustment component. The imaging light curtain 4 is disposed on the third adjustment component. The third adjustment component includes a distance adjustment mechanism 41 and a height adjustment mechanism 42. The distance adjustment mechanism 41 is used to adjust the distance between the imaging light curtain 4 and the feeding component 1, and the height adjustment mechanism 42 is used to adjust the height of the imaging light curtain 4.

[0100] In this embodiment, the third adjustment component is used to adjust the distance and height of the imaging light curtain 4. The distance adjustment is achieved by a distance adjustment mechanism 41, which adjusts the distance between the imaging light curtain 4 and the loading component 1, specifically to adjust the distance between the imaging light curtain 4 and the vehicle headlight 7 on the loading component 1. The distance adjustment mechanism 41 can employ a precision slide rail, lead screw, or cylinder to achieve accurate distance control. It can also be equipped with an encoder or sensor for real-time feedback and adjustment of the distance. The height adjustment mechanism 42 is used to adjust the height of the imaging light curtain 4 to receive light from the vehicle headlight 7, thereby more accurately reflecting the focusing state of the vehicle headlight 7. The height adjustment mechanism 42 can employ a lifting platform, bracket, or similar device, achieving precise height control through a motor, pneumatic, or hydraulic means. It can also be equipped with an encoder or sensor for real-time feedback and adjustment of the height. If an illuminance meter is installed, it is typically mounted on the same third adjustment component as the imaging light curtain 4 for synchronous adjustment.

[0101] In addition, please see Figure 15 The headlight focusing adjustment system 7 typically needs to prevent interference from external light. Therefore, all components can be housed within a closed housing 81. Multiple openable doors can be installed on the housing 81 for easy access and maintenance. An openable small door or a light-shielding cloth can be installed at the headlight 7's loading area. The entire headlight focusing adjustment system 7 can be mounted on a main frame 8. Casters 82 are installed under the main frame 8 for easy movement, and adjustable support legs 83 can be provided for stable support once in position.

[0102] The following is a possible operation flow for this embodiment:

[0103] The feeding assembly 1 for loading the vehicle lights 7 is loaded manually or automatically.

[0104] The feeding assembly 1 adjusts the headlight 7 to the focus adjustment position, and uses the first adjustment assembly and / or the second adjustment assembly to achieve precise position and angle adjustment of the headlight 7;

[0105] The headlight 7 test begins. The light emitted by the headlight 7 shines on the imaging light screen 4. The image acquisition component 5 acquires the image presented on the imaging light screen 4 and transmits it to the image processing component for analysis.

[0106] Based on the analysis structure of the image processing component, the focal length of the headlight 7 is adjusted;

[0107] The image acquisition component 5 acquires the image presented on the imaging light screen 4 again and transmits it to the image processing component for analysis to determine whether it meets the target focal length requirements;

[0108] With the assistance of the second adjustment component and the first adjustment component, the lens 72 of the headlight 7 is oriented toward the fixed component 3;

[0109] Fixing component 3 fixes the focal length of headlight 7;

[0110] The headlight 7, after being fixed in focus, is unloaded from the loading assembly 1, either manually or automatically, to complete the focusing adjustment of the headlight 7.

[0111] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
