By using the automotive headlight illumination performance testing device, problems with vehicle headlights can be detected and corrected in a timely manner, ensuring that the vehicle can provide good lighting effects when driving at night and improving driving safety. For example, utility model patent CN215832975U discloses an automotive headlight detector, including a headlight detector with a bracket fixedly connected to its outer front end. A motor is fixedly connected to the bottom left side of the bracket, and a fixed shaft is fixedly connected to the end of the motor's main shaft. A dustproof cloth is fixedly connected to the center position of the outer side of the fixed shaft. Rollers are provided on both sides of the dustproof cloth, and the rollers are fixedly connected to the fixed shaft. A connecting line is fixedly connected to the outer side of the rollers. In this patent, the sponge brush, dustproof cloth, and connecting line achieve shielding and protection of the headlight detector's detection surface when the device is in use, while also automatically cleaning dust and foreign objects from the detection surface. This ensures the accuracy of automotive light intensity detection, guarantees the normal use of the device, reduces the labor intensity of operators, and avoids potential scratches to the equipment caused by manual cleaning. However, in the existing technology, the device lacks a limiting mechanism after reaching the designated position, making it difficult to limit the device's movement and causing instability when placed at the designated position. Furthermore, the lack of a rotation mechanism makes it difficult to adjust the orientation of the detection device, resulting in inconvenient use. Therefore, improvements are needed. Utility Model Content

[0003] The purpose of this utility model is to provide a vehicle headlight illumination performance testing device, which solves the problems that when the device reaches the designated position, the device lacks a limiting mechanism, making it difficult to limit the device and causing it to be unstable when placed at the designated position. In addition, the device lacks a rotation mechanism, making it difficult to adjust the direction of the main body of the testing device, which makes the device inconvenient to use.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a vehicle headlight illumination performance testing device, comprising a base plate, a support column contacting the upper end of the base plate, a first motor fixedly installed inside the support column, a screw fixedly connected to the lower end of the rotating shaft of the first motor, the screw being rotatably connected to the support column, a bearing fixedly sleeved inside the support column, a screw fixedly sleeved inside the inner ring of the bearing, a connecting block threadedly connected to the outer side of the screw, the connecting block being slidably connected to the support column, a testing device body fixedly installed on the connecting block, a rotating mechanism provided inside the base plate, and a limit mechanism provided at the lower end of the base plate.

[0005] Preferably, the rotating mechanism includes a rotating block, which is rotatably connected inside the base plate. The rotating block is fixedly connected to a support column, and a rotating sleeve is fixedly connected to the outside of the rotating block. An annular groove is formed inside the rotating sleeve, and an annular sleeve is slidably connected inside the annular groove. The annular sleeve is fixedly connected to the base plate. A slot is formed inside the rotating sleeve, and a slider is slidably connected inside the slot. A support ring is fixedly connected to the end of the slider away from the slot. A pull rod is slidably connected inside the base plate, and a spring is provided on the outside of the pull rod. The base plate is slidably connected to the slider. By pulling the slider out of the slot, and then rotating the support column, the slot and the main body of the detection device are rotated to a designated position. Then, the slider is moved to another slot, thereby limiting the movement of the main body of the detection device and allowing for directional adjustment, making the device easy to use.

[0006] Preferably, a pull rod is fixedly connected to the side of the support ring away from the slider, and a handle is fixedly connected to the end of the pull rod away from the support ring. By designing the handle, the pull rod can be moved.

[0007] Preferably, one end of the spring is fixedly connected to the support ring, and the other end of the spring is fixedly connected to the base plate. By designing the spring, the support ring has an elastic force.

[0008] Preferably, the limiting mechanism includes a base, with a base fixedly connected to the lower end of the base plate.

The piston and the threaded sleeve are fixedly connected. By activating the second motor, the threaded rod and threaded sleeve undergo threaded movement. The threaded sleeve moves upward, causing the piston and other components to move upward. The upward movement of the piston expels the gas inside the suction cup, creating negative pressure in the suction cup, which then adheres to the ground, ensuring the device is stably placed in the designated position.

[0009] Preferably, a guide rod is slidably connected inside the guide sleeve, and the guide rod is fixedly connected to the piston. By designing the guide rod, the piston can be guided.

[0011] 1. This utility model is designed with components such as a base, an exhaust hole, a connecting rod, a cylinder, a suction cup, and a second motor. The second motor drives the threaded rod and the threaded sleeve to move in a threaded motion. The threaded sleeve moves upward, which drives the piston and other components to move upward. The piston moves upward and discharges the gas in the suction cup upward, thereby creating a negative pressure in the suction cup, which in turn causes the suction cup to stick to the ground, making the device stable in the designated position.

[0012] 2. This utility model designs components such as a rotating block, rotating sleeve, annular groove, annular sleeve, slot, and slider. Pulling the slider moves it out of the slot, and then rotating the support column drives the slot and the main body of the detection device to rotate to a designated position.

[0021] Please see Figure 4The rotating mechanism 8 includes a rotating block 81, which is rotatably connected inside the base plate 1. The rotating block 81 is fixedly connected to the support column 2. A rotating sleeve 82 is fixedly connected to the outside of the rotating block 81. An annular groove 83 is formed inside the rotating sleeve 82. An annular sleeve 84 is slidably connected inside the annular groove 83 and is fixedly connected to the base plate 1. A slot 85 is formed inside the rotating sleeve 82. A slider 86 is slidably connected inside the slot 85. A support ring 87 is fixedly connected to the end of the slider 86 away from the slot 85. A pull rod 88 is fixedly connected to the side of the support ring 87 away from the slider 86. A handle 89 is fixedly connected to the end of the pull rod 88 away from the support ring 87. By designing the handle 89, it is possible to carry... The movable pull rod 88 moves, and the pull rod 88 is slidably connected inside the base plate 1. A spring 810 is provided on the outside of the pull rod 88. One end of the spring 810 is fixedly connected to the support ring 87, and the other end of the spring 810 is fixedly connected to the base plate 1. By designing the spring 810, the support ring 87 has an elastic force. The base plate 1 is slidably connected to the slider 86. By pulling the slider 86, it moves out of the slot 85. Then, the support column 2 is rotated to drive the slot 85 and the detection device body 7 and other components to rotate to the designated position. Then, the slider 86 is moved into another slot 85, thereby limiting the detection device body 7 and other components, thereby allowing the detection device body 7 to be directionally adjusted, making the device easy to use.

[0022] Please see Figure 1 , Figure 2 , Figure 3 , Figure 5 The limiting mechanism 9 includes a base 91, which is fixedly connected to the lower end of the base plate 1. An exhaust hole 92 is provided inside the base 91. A connecting rod 93 is fixedly connected inside the base 91, and a cylinder 94 is fixedly connected to the connecting rod 93. A suction cup 95 is fixedly connected to the outer side of the cylinder 94. A second motor 96 is fixedly installed inside the base 91. A threaded rod 97 is fixedly connected to the lower end of the rotating shaft of the second motor 96. A threaded sleeve 98 is threadedly connected to the outer side of the threaded rod 97. A piston 99 is slidably connected inside the cylinder 94, and a guide sleeve 95 is fixedly connected inside the base 91. 10. A guide rod 911 is slidably connected inside the guide sleeve 910. The guide rod 911 is fixedly connected to the piston 99. By designing the guide rod 911, the piston 99 can be guided. The piston 99 is fixedly connected to the threaded sleeve 98. By starting the second motor 96, the threaded rod 97 and the threaded sleeve 98 are driven to move in a threaded motion. The threaded sleeve 98 moves upward, which drives the piston 99 and other components to move upward. The upward movement of the piston 99 discharges the gas in the suction cup 95 upward, thereby generating negative pressure in the suction cup 95, which in turn causes the suction cup 95 to stick to the ground, making the device stable in the designated position.

[0023] The specific implementation process of this utility model is as follows: When the device reaches the designated position, the second motor 96 is started. The second motor 96 drives the threaded rod 97 to rotate. The rotation of the threaded rod 97 causes threaded movement with the threaded sleeve 98, which in turn causes the threaded sleeve 98 to have a relative displacement. The threaded sleeve 98 moves upward, which drives the piston 99 to move upward. The piston 99 moves upward, which drives the guide rod 911 to move upward. The piston 99 moves upward, which discharges the gas in the suction cup 95 upward, which in turn causes the suction cup 95 to generate negative pressure, which in turn causes the suction cup 95 to stick to the ground, so that the device is placed stably at the designated position.

[0024] When the main body 7 of the detection device needs directional adjustment, pull the handle 89 towards the base plate 1. The movement of the handle 89 moves the pull rod 88, which in turn moves the support ring 87. The movement of the support ring 87 moves the slider 86. Simultaneously, the movement of the support ring 87 compresses the spring 810, causing the slider 86 to move out of the slot 85. Then, the support column 2 is rotated, causing the rotating block 81, rotating sleeve 82, annular groove 83, slot 85, and the main body 7 of the detection device to rotate. After the support column 2, slot 85, and the main body 7 of the detection device rotate to the designated position, the handle 89 is released. The elastic force of the spring 810 pushes the support ring 87 to move, which in turn moves the slider 86 and other components. The slider 86 moves into the slot 85, thereby limiting the movement of the main body 7 of the detection device and thus allowing for directional adjustment of the main body 7 of the detection device, making the device easy to use.
