DETAILED DESCRIPTION

[0044] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

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

[0046] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0047] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0048] With the development of smart cars, the functions and technologies of car lights 7 are constantly evolving, gradually transforming from traditional lighting tools to intelligent visual systems. In particular, the widespread application of digital light processing technology has enabled car lights 7 to not only provide basic lighting functions, but also achieve more complex and diverse light control and display effects.

[0049] Digital light processing technology is referred to as DLP technology. It can achieve high-precision light control through micro-lens arrays and digital signal processing. The introduction of this technology enables the headlight 7 to automatically adjust the shape, intensity and direction of the light beam according to different driving environments and needs. For example, when driving at night, the DLP headlight 7 can intelligently adjust the light beam according to the distance and position of the vehicle in front to avoid glare to other drivers while ensuring that the driver has the best field of vision. This flexibility not only improves driving safety, but also provides more reliable visual support for intelligent driving.

[0050] However, currently, the process of adjusting the focus of the headlight 7 mostly relies on manual operation, which is not only inefficient, but also difficult to ensure the consistency and accuracy of the adjustment. During the manual adjustment process, workers need to judge and adjust the focus of the headlight 7 based on experience, which is not only time-consuming, but also easily affected by human factors, resulting in unstable focusing effect.

[0051] See also Figure 1 Now, the focusing adjustment system of the headlight 7 provided in the embodiment of the present application is described. The focusing adjustment system of the headlight 7 includes:

[0052] Feeding assembly 1; the feeding assembly 1 is used to limit the headlight 7 to the focal length adjustment position;

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

[0054] Fixing component 3: The fixing component 3 is used to fix the focal length of the vehicle light 7 at the target focal length.

[0055] In this embodiment, the main function of the loading assembly 1 is to restrict the headlight 7 to the focal length adjustment station so that the subsequent focusing operation can be performed accurately. Specifically, the loading assembly 1 can only play the role of fixing the headlight 7, or it can also play the role of moving and adjusting the headlight 7. The loading assembly 1 can adopt a variety of structures. For example, the loading assembly 1 can be a mechanical clamp, using clamps of various shapes and sizes to clamp the headlight 7 to ensure that it is stably placed on the focal length adjustment station; the loading assembly 1 can also be a pneumatic or hydraulic drive device, which drives the opening and closing of the clamp through air pressure or hydraulic pressure to achieve rapid loading and positioning of the headlight 7; the loading assembly 1 can also be a conveyor belt or a robot arm, which is used to move the headlight 7 from the storage position to the focal length adjustment station.

[0056] The focusing assembly 2 is arranged at the focal length adjustment station, and is used to accurately adjust the focal length of the headlight 7 until the target focal length is reached. The target focal length here refers to the ideal focal length that the headlight 7 is expected to achieve after focusing. The focusing assembly 2 can be a motor rotation drive system, which uses a stepper motor or a servo motor to drive the lens 72 of the headlight 7 to rotate, so as to achieve fine adjustment of the focal length. The focusing assembly 2 can also be a moving mechanism, which achieves fine adjustment of the focal length by moving the headlight 7 to obtain the lens 72 or the reflector. In addition, the focusing assembly 2 can also cooperate with a sensor and a control system, and the focusing structure is fed back by the sensor detection, and the precise focusing of the focusing assembly 2 is controlled by the control system.

[0057] Once the focal length of the headlight 7 is adjusted to the target focal length, the fixing component 3 will function to fix the focal length at this position to prevent changes during subsequent operations or transportation. The fixing component 3 may use a mechanical fastening mechanism, such as screw locking, snap locking, etc. The fixing component 3 may also be fixed by bonding with adhesive.

[0058] When the focusing adjustment system of the headlight 7 of this embodiment is in use, the headlight 7 can be placed on the loading component 1 manually or automatically. The loading component 1 is used to fix or move the headlight 7 to the focal length adjustment station; the focusing component 2 performs focusing operation on the headlight 7 so that the focal length of the headlight 7 reaches the target focal length; once the focal length is adjusted to the target value, the fixing component 3 fixes the focal length of the headlight 7 at the target focal length, thereby completing the focusing of the headlight 7.

[0059] The focusing adjustment system of the vehicle headlight 7 of this embodiment directly uses the fixing component 3 to fix after the focusing component 2 is focused. Compared with manual focusing, it can effectively improve efficiency, and has better adjustment accuracy and stability, can greatly reduce manual errors, and is also relatively easy to operate.

[0060] Please refer to Figures 2 to 4 In some embodiments of the present application, the loading assembly 1 includes a plug-in 12 and a first clamping mechanism 11. The plug-in 12 is used to be plugged into the headlight 7. The plug-in 12 is arranged along a first direction, and the first clamping mechanism 11 is used to clamp the headlight 7 along the first direction.

[0061] In this embodiment, the loading assembly 1 includes a plug-in 12 and a first clamping mechanism 11, wherein the plug-in 12 is a bridge for positioning the headlight 7 and the loading assembly 1. By plugging into a specific part of the headlight 7, the loading assembly 1 and the headlight 7 are quickly positioned to prevent the headlight 7 from shifting during the clamping and fixing process. The specific structure of the plug-in 12 can be designed according to the specific part of the headlight 7, and the mounting hole, slot or protrusion of the headlight 7 can usually be selected as the specific part. For example, if the specific part is the mounting hole or positioning hole of the headlight 7, the plug-in 12 can be a rod-shaped member, and the positioning of the headlight 7 is achieved by inserting the rod-shaped member into the mounting hole or positioning hole. For another example, if the specific part is the protrusion of the headlight 7, the plug-in 12 can be a structure with a concave hole, and the positioning of the headlight 7 is achieved by the mutual engagement of the protrusion and the concave hole.

[0062] The plug-in 12 is arranged along a first direction, the first direction being Figure 2 The A direction in the figure, therefore, the vehicle lamp 7 and the plug-in unit 12 are mutually inserted and positioned along the first direction. The first direction is different according to the selection of the specific part of the vehicle lamp 7. For example, if the mounting hole or the positioning hole of the vehicle lamp 7 is selected as the specific part, the axial direction of the mounting hole or the positioning hole is the first direction. The first direction here includes two relative positive and negative directions.

[0063] The headlight 7 is clamped and fixed by the first clamping mechanism 11, and the clamping mechanism can be a pneumatic, electric or mechanical clamp. The pneumatic clamp drives the clamp to open and close by air pressure; the electric clamp is driven by a motor and has higher precision and controllability; the mechanical clamp 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 headlight 7 along the first direction, and the first direction is the setting of the plug-in 12 along the first direction. Therefore, during the clamping process of the first clamping mechanism 11, the plug-in 12 and the headlight 7 can be plugged in and positioned. At the same time, the plug-in 12 can also guide the clamping of the first clamping mechanism 11, thereby ensuring that the headlight 7 will not be offset during the clamping process of the first clamping mechanism 11.

[0065] During operation, the headlight 7 can be placed on the loading assembly 1 manually or by automated machinery, and attention should be paid to aligning a specific part of the headlight 7 with the plug-in 12 for insertion. The first clamping mechanism 11 clamps the headlight 7 along the first direction to achieve stable fixation of the headlight 7.

[0066] Please refer to Figure 2 and Figure 3 In some embodiments of the present application, the plug-in 12 includes a plug-in rod 121, and the plug-in rod 121 is used to be plugged into the first hole of the vehicle lamp 7.

[0067] The plug-in 12 is a key component used to connect with the headlight 7 in the focusing adjustment system of the headlight 7. It is plugged into a specific part of the headlight 7 to achieve the positioning of the headlight 7 and the loading assembly 1. In this embodiment, the plug-in 12 is a plug-in rod 121, and the shape of the plug-in rod 121 is determined according to the shape of the first hole on the headlight 7. The first hole can be a mounting hole or a positioning hole of the headlight 7, and the plug-in rod 121 can be set on the bracket of the loading assembly 1 to ensure its force performance.

[0068] The number of the plug-in rods 121 can be one or more, and the number of the first holes of the headlight 7 must also be one or more, and the two numbers are consistent. The plugging of multiple plug-in rods 121 and multiple first holes can prevent the rotation that may occur when a single plug-in rod 121 is plugged into a single first hole. For example, Figure 2 The embodiment shown in FIG. 1 adopts a method of plugging two plugging rods 121 and two first holes.

[0069] Please refer to Figure 4 In some embodiments of the present application, the first clamping mechanism 11 includes a first clamping portion 111 and a second clamping portion 112 which can be close to each other, the first clamping portion 111 is used to abut against the first side of the mounting portion 71 of the headlight 7, and the second clamping portion 112 is used to abut against the second side of the headlight 7, and the first side is the opposite side of the second side.

[0070] The first clamping mechanism 11 is used to clamp and fix the headlight 7 so as to facilitate focusing adjustment of the headlight 7. The first clamping mechanism 11 clamps the headlight 7 through the first clamping portion 111 and the second clamping portion 112 which can be close to each other. The first clamping portion 111 is used to abut against the first side of the mounting portion 71 of the headlight 7, and the second clamping portion 112 is used to abut against the second side of the mounting portion 71 of the headlight 7. The first side is the opposite side of the second side, that is, the first clamping portion 111 and the second clamping portion 112 are clamped on both sides of the mounting portion 71 of the headlight 7, respectively. The mounting portion 71 of the headlight 7 is the part where the headlight 7 is installed and fixed, and it has relatively high strength, and can support and stabilize the entire headlight 7. The mounting portion 71 of the headlight 7 is clamped by the first clamping portion 111 and the second clamping portion 112, so as to ensure the stability of the clamping of the headlight 7.

[0071] The first clamping part 111 and the second clamping part 112 can be driven by pneumatic or electric means, so that the two 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 portion 111 abuts against the upper and lower mounting holes of the mounting portion 71 of the headlight 7, while the second clamping portion 112 abuts against the middle of the opposite side of the mounting portion 71. The second clamping portion 112 is connected to the first cylinder 113 through a lever structure, and the first cylinder 113 drives the movement of the second clamping portion 112 to make it close to the first clamping portion 111, thereby clamping the headlight 7. In addition, if the headlight 7 has a fixed circuit interface, a corresponding module can be provided on the first clamping mechanism 11 to be plugged therein, thereby further ensuring the accuracy of the position of the headlight 7.

[0072] Please refer to Figure 5 and Figure 6 In some embodiments of the present application, the loading assembly 1 further includes an abutment mechanism 13, and the abutment mechanism 13 is used to abut the vehicle lamp 7 along a second direction, and the second direction is perpendicular to the first direction.

[0073] Since there is a certain gap when the plug-in 12 is plugged into the headlight 7, although the plug-in 12 can be stabilized to a large extent, there is still a certain amount of shaking in the second direction perpendicular to the first direction, such as Figure 5 As shown, the second direction is the B direction in the figure, and the first direction is the A direction, and the A direction is perpendicular to the B direction. For this reason, in the present embodiment, the feeding assembly 1 further includes an abutment mechanism 13, and the abutment mechanism 13 is used to abut the headlight 7 along the second direction, and the second direction is perpendicular to the first direction. The first direction is the plug-in direction of the plug-in 12, that is, the abutment mechanism 13 can abut the headlight 7 in a direction perpendicular to the plug-in direction of the plug-in 12, thereby reducing the impact of the gap that may exist when the plug-in 12 and the headlight 7 are plugged in, thereby more accurately positioning the headlight 7, and further ensuring that the first clamping mechanism 11 accurately clamps the headlight 7. The second direction here includes two relative positive and negative directions.

[0074] The contact mechanism 13 can adopt an electric, pneumatic or other telescopic structure to achieve contact with the vehicle lamp 7. Figure 6 In the illustrated embodiment, the abutment mechanism 13 includes a second cylinder 132 and an abutment rod 131 driven by the second cylinder 132. The second cylinder 132 can drive the abutment rod 131 to abut against one side of the vehicle lamp 7. A plurality of selectable mounting holes are provided at the mounting position of the abutment rod 131, so that the abutment rod 131 can be installed in different mounting holes to adjust the position of the abutment rod 131.

[0075] Please refer to Figure 7 In some embodiments of the present application, the loading component 1 also includes a first adjustment component, the first adjustment component includes a first adjustment mechanism 141, a second adjustment mechanism 142 and a third adjustment mechanism 143 that are interconnected, the first adjustment mechanism 141 is used to adjust the position of the headlight 7 in the third direction, the second adjustment mechanism 142 is used to adjust the position of the headlight 7 in the fourth direction, and the third adjustment mechanism 143 is used to adjust the position of the headlight 7 in the 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 above, the loading assembly 1 can only play the role of fixing the headlight 7, and can also play the role of moving and adjusting the headlight 7 at the same time. In this embodiment, the loading assembly 1 also includes a first adjustment assembly, which can realize the role of moving and adjusting the headlight 7, so as to accurately move the headlight 7 to the focal length adjustment position. The first adjustment assembly includes a first adjustment mechanism 141, a second adjustment mechanism 142 and a third adjustment mechanism 143. The 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 the third direction, the second adjustment mechanism 142 is used to adjust the position of the headlight 7 in the fourth direction, and the third adjustment mechanism 143 is used to adjust the position of the headlight 7 in the 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. It can be seen that the third direction, the fourth direction and the fifth direction actually form a spatial rectangular coordinate system, wherein the third direction, the fourth direction and the fifth direction correspond to one of the X-axis, the Y-axis and the Z-axis respectively. The first adjustment mechanism 141, the second adjustment mechanism 142 and the third adjustment mechanism 143 can adopt a pneumatic or electric drive member in conjunction with a sliding track and other structures, so that the first adjustment mechanism 141 moves along the third direction, the second adjustment mechanism 142 moves along the fourth direction, and the third adjustment mechanism 143 moves along the fifth direction, thereby achieving adjustment of the vehicle lamp 7 in a three-dimensional space. The third direction, the fourth direction and the fifth direction also respectively include two relative directions, positive and negative.

[0077] like Figure 7 In the illustrated embodiment, 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 arranged on the first adjustment component. The three adjustment mechanisms in the first adjustment component are respectively responsible for an X-axis, a Y-axis and a Z-axis. Among them, 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 Figure 8 and Fig. 9In some embodiments of the present 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 headlight 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 headlight 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. The present embodiment includes a second clamping mechanism 21 and a first rotating mechanism 22. The focusing principle of the present 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 to ensure that the lens 72 can stably follow the movement of the first rotating mechanism 22 when adjusting the focal length. The second clamping mechanism 21 can adopt a variety of clamping parts such as a clamping claw type and a chuck type. 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 driving part such as a stepping motor, a servo motor, etc., and can drive the second clamping mechanism 21 to rotate through a synchronous belt, gears, etc.

[0080] When adjusting the focal length, the main part of the headlight 7 is fixed by the loading assembly 1, and at the same time 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, and then drive the lens 72 to rotate relative to the main part of the headlight 7, thereby realizing the adjustment of the focal length of the headlight 7.

[0081] In such Fig. 9 In the illustrated embodiment, the second clamping mechanism 21 includes a clamping cylinder 211 disposed up and down, driving the upper and lower clamping jaws 212 to clamp the lens 72 of the headlight 7. In order to protect the headlight 7, soft rubber is also provided at the contact portion between the clamping jaws 212 and the headlight 7.

[0082] Please refer to Fig.10 and Fig.11 In some embodiments of the present application, the fixing component 3 includes a dispensing mechanism 31 and a curing mechanism 32 , the dispensing mechanism 31 is used to output adhesive to the lens 72 of the headlight 7 , and the curing mechanism 32 is used to cure the adhesive.

[0083] In this embodiment, the fixing component 3 uses glue dispensing to fix the focal length of the headlight 7. The fixing component 3 is mainly composed of two key parts: a glue dispensing mechanism 31 and a curing mechanism 32. The main function of the glue dispensing mechanism 31 is to output adhesive glue to the headlight 7. The main function of the glue dispensing mechanism 31 is to output adhesive glue to the headlight 7. After the focusing of the headlight 7 is completed, the glue dispensing mechanism 31 can accurately apply the adhesive glue to the lens 72 of the headlight 7 to fix the lens 72, thereby achieving focal length fixation. The main function of the curing mechanism 32 is to cure the adhesive glue, that is, to allow the adhesive glue applied to the lens 72 of the headlight 7 to dry and harden quickly, thereby fixing the lens 72 and maintaining the stability of the focal length. The glue dispensing mechanism 31 can adopt a pneumatic glue dispensing machine, an electric precision glue dispensing machine, etc., and the curing mechanism 32 can be set correspondingly for different adhesives. For example, for thermosetting glue, the curing mechanism 32 can adopt a thermal curing device to accelerate the chemical reaction of the adhesive glue by heating, so that it can be cured quickly. For light-curing glue, the curing mechanism 32 may be a UV curing device, which emits ultraviolet light, and uses ultraviolet light to cause a photochemical reaction in the chemical substances in the adhesive, thereby achieving rapid curing. Fig.11 In the illustrated embodiment, the curing mechanism 32 is a UV curing device.

[0084] Please refer to Fig.10 , Fig.12 and Fig.13 In some embodiments of the present application, the fixing component 3 and the focusing component 2 are located on different sides of the loading component 1; the loading component 1 also includes a second adjustment component, the second adjustment component includes a flipping mechanism 151 and a second rotating mechanism 152, the flipping mechanism 151 is used to flip the lens 72 of the headlight 7 to the side where the fixing component 3 is located, and 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 the area toward the dispensing mechanism 31 in the circumferential direction.

[0085] The headlight 7 is mounted on the loading assembly 1, so the side where the fixing assembly 3 and the focusing assembly 2 are located relative to the loading assembly 1 is the side where the fixing assembly 3 and the focusing assembly 2 are located relative to the headlight 7. In this embodiment, the fixing assembly 3 and the focusing assembly 2 are located on different sides of the loading assembly 1, so that the positions of the fixing assembly 3 and the focusing assembly 2 can be prevented from interfering with each other, so that both have relatively ample space for arrangement.

[0086] However, the fixing component 3 and the focusing component 2 are located on different sides of the loading component 1, so that after the headlight 7 uses the focusing component 2 to adjust the focal length, it is necessary to readjust the position to the side where the fixing component 3 is located in order to fix the focal length. To this end, the loading component 1 of the present embodiment also includes a second adjustment component, and the second adjustment component includes a flipping mechanism 151 and a second rotating mechanism 152, wherein the flipping mechanism 151 can flip the lens 72 of the headlight 7 from the side where the focusing component 2 is located to the side where the fixing component 3 is located after the focusing is completed, so as to perform subsequent fixing operations. The flipping mechanism 151 can adopt a driving device such as a rotating motor and a cylinder, and realize the flipping of the lens 72 through a transmission mechanism such as a connecting rod and a 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 the area toward the dispensing mechanism 31 in the circumferential direction, thereby realizing the dispensing of 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 adopt a driving device such as a rotating motor or a stepping motor to realize the rotation of the vehicle light 7 through a transmission mechanism such as a bearing or a coupling.

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

[0088] In other embodiments, the fixing component 3 and the focusing component 2 are located on the same side of the loading component 1. Although this makes the arrangement of the fixing component 3 and the focusing component 2 more compact, there is no need to set a flipping mechanism 151 to flip the headlight 7. The fixing component 3 can be used to fix the lens 72 of the headlight 7, thereby fixing the focal length of the headlight 7.

[0089] Please refer to Figure 1 In some embodiments of the present application, the focusing adjustment system of the vehicle light 7 further includes:

[0090] Imaging light curtain 4; the imaging light curtain 4 is used to receive and present an image formed by the light emitted by the vehicle lamp 7;

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

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

[0093] The focusing component 2 is used to adjust the focal length of the vehicle light 7 according to the analysis result of the image processing component.

[0094] In this embodiment, the imaging light curtain 4 is mainly used to receive and present the image formed by the light emitted by the headlight 7, so that the image acquisition component 5 can collect the image. The shape and size of the imaging light curtain 4 can be customized according to the type and use requirements of the headlight 7, such as a flat surface, a curved surface or a specific angle design. In order 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 different headlights 7.

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

[0096] The image processing component is used to analyze the image collected by the image acquisition component 5. The image processing component can be an image processor that can process and analyze the collected image in real time. The image processing component can also include a user interface for displaying the analysis results and performing manual adjustments. The focusing component 2 automatically adjusts the focal length of the headlight 7 according to the analysis results of the image processing component to ensure accurate focusing of the light. In addition, an illuminance meter can also be set at the position of the molding light curtain to detect the illumination of the headlight 7.

[0097] Please refer to Figure 1 In some embodiments of the present application, the focusing adjustment system of the headlight 7 further includes a telescope 6, which is used to shorten the optical path of the headlight 7;

[0098] Since the illumination distance of the headlight 7 is usually long, and the system site or space for testing is usually unable to directly meet the requirements of the illumination distance of the headlight 7, in this embodiment, the focusing adjustment system of the headlight 7 also includes a telescope 6, which can shorten the optical path of the headlight 7. This means that it can focus a light beam that originally requires a long distance to form a focus within a shorter distance. This is very useful for vehicle design, especially those with limited space, because it allows effective lighting testing within a limited space. The telescope 6 is set at a position corresponding to the lens 72 of the headlight 7, for example, it can be set on the focusing assembly 2. The telescope 6 can usually adopt a relay lens, and the telescope 6 uses the telescope's telescoping effect to achieve the telescoping of the headlight 7 light. Figure 1 Taking the embodiment in the figure as an example, the relay mirror of this embodiment can shrink the image from 10m to 0.9m and ensure that the image is not distorted.

[0099] Please refer to Fig.14In some embodiments of the present application, the focusing adjustment system of the vehicle light 7 also includes a third adjustment component, the imaging light curtain 4 is arranged on the third adjustment component, and 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, wherein the distance adjustment is realized by the distance adjustment mechanism 41, and the distance adjustment mechanism 41 is used to adjust the distance between the imaging light curtain 4 and the feeding component 1, and its purpose is to adjust the distance between the imaging light curtain 4 and the headlight 7 on the feeding component 1. The distance adjustment mechanism 41 can adopt a precise slide rail, a lead screw or a cylinder structure to achieve precise distance control. It can also be equipped with an encoder or a sensor to feedback and adjust the distance in real time. Height adjustment mechanism 42: This mechanism is used to adjust the height of the imaging light curtain 4 so as to receive light from the headlight 7, thereby more accurately reflecting the focusing state of the headlight 7. The height adjustment mechanism 42 can adopt a lifting platform, a bracket or a similar device to achieve precise height control through a motor, pneumatic or hydraulic method. It can also be equipped with an encoder or a sensor to feedback and adjust the height in real time. If an illuminance meter is provided, the illuminance meter and the imaging light curtain 4 are usually installed on the third adjustment component so that the illuminance meter and the imaging light curtain 4 can be adjusted synchronously.

[0101] In addition, see Fig.15 The focusing adjustment system of the headlight 7 usually needs to prevent interference from external light. Therefore, all components can be set in a closed shell 81, and multiple openable doors can be set on the shell 81 to facilitate inspection and maintenance. An openable small door or a blackout cloth can be set at the loading point of the headlight 7. The entire focusing adjustment system of the headlight 7 can be set on a main frame 8, and rollers 82 are set under the main frame 8 for easy movement. Adjustable feet 83 can also be set to provide stable support after moving into place.

[0102] The following is a possible action flow of this embodiment:

[0103] The lamp 7 is manually or automatically loaded onto the loading assembly 1;

[0104] The loading assembly 1 adjusts the headlight 7 to the focal length 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 test of the headlight 7 begins, and the light emitted by the headlight 7 is irradiated onto the imaging light curtain 4. The image acquisition component 5 acquires the image presented on the imaging light curtain 4 and transmits it to the image processing component for analysis;

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

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

[0108] The lens 72 of the headlight 7 is directed toward the fixing assembly 3 by using the second adjusting assembly in cooperation with the first adjusting assembly;

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

[0110] The headlight 7 with a fixed focal length is manually or automatically removed from the loading assembly 1 to complete the focus adjustment of the headlight 7 .
