The outer surface of each slider 5 is slidably connected to the fixing frame 2. The first motor 3 is started to drive the bidirectional screw 4 to rotate. The rotation of the bidirectional screw 4 will drive the two sliders 5 to move horizontally along the bidirectional screw 4 at the same time. The lengths of the two sliders 5 from the middle position of the bidirectional screw 4 are the same. When the two sliders 5 move, their moving directions are opposite or opposite.

Please refer to Figures 1 and 4. The outer surface of the bidirectional screw 4 is rotatably connected to the fixed frame 2. The inner wall of each slider 5 is rotatably connected to the first connecting plate 6. The inner wall of the fixed frame 2 is slidably connected to the detection plate 7. The outer surface of each first connecting plate 6 is rotatably connected to the detection plate 7. A control panel 8 is fixedly installed on the outer surface of the frame 1. The connection between the sliders 5 and the detection plate 7 is achieved by the first connecting plates 6. During the movement of the two sliders 5, the detection plate 7 is pushed by the two first connecting plates 6 to move vertically along the fixed frame 2. In this way, the lighting heights of different types of vehicles when meeting can be simulated. The detection plate 7 can detect the light intensity of the motor vehicle. The control panel 8 can perform PLC control on the circuits and components inside the frame 1.

Please refer to Figure 3. The outer surface of the first connecting rod 11 is fixedly connected to a plurality of first bevel gears 12, and the outer surface of each first bevel gear 12 is meshed with a second bevel gear 13. The end of each second bevel gear 13 away from the corresponding first bevel gear 12 is fixedly connected to the second connecting rod 14, and the outer surface of each second connecting rod 14 is rotatably connected to a fixed block 17. The outer surface of each fixed block 17 is slidably connected to the frame 1.

The fixed block 17 will move horizontally along the frame 1, and the fixed block 17 will move with the placement box 10.

Please refer to Figure 3. The top of each second connecting rod 14 is fixedly connected to a spur gear 15, the outer surface of each spur gear 15 is meshed with a rack 16, the outer surface of each rack 16 is fixedly connected to a clamping plate 18, and the outer surface of each rack 16 is slidably connected to the corresponding fixed block 17.

When the wheel leaves the support plate 19, the spring 23 pushes the support plate 19 under the action of its rebound force to block and limit the wheel.

The implementation principle of a motor vehicle lighting detection device in an embodiment of the present application is as follows: first, the motor vehicle is driven along the frame 1 to the transmission belt 24. At this time, the wheels on both sides of the vehicle body will crush the support plate 19 and compress the spring 23, and the third connecting rod 22 will enter the corresponding fixed column 21. Then, when the wheel passes, the support plate 19 will be bounced up and support the wheel under the action of the rebound force of the spring 23 to prevent the vehicle from slipping. Then, the second motor 9 is started. The second motor 9 will mesh between the first bevel gear 12 and the second bevel gear 13 and mesh between the spur gear 15 and the corresponding rack 16 so that the rack 16 pushes the corresponding clamping plate 18 to clamp and fix wheels of different sizes. Then, the transmission belt 24 is controlled by the PLC to drive the vehicle body to move horizontally, thereby simulating the shortening of the distance when meeting other vehicles.
