[0001] The utility model relates to the technical field of lighting detection, in particular to a motor vehicle lighting detection device. Background Art

[0002] A motor vehicle lighting detection device is a device used to inspect and adjust the vehicle lighting system. This device is usually used to ensure that lighting components such as the vehicle's headlamps, tail lamps, and turn signals work properly, and their brightness, irradiation angle and other parameters meet the requirements of road traffic safety regulations.

[0003] Currently, the patent with the publication number CN221078017U discloses a motor vehicle lighting auxiliary detection device, including a detection board and a in-place detection component; the detection board is vertically arranged on a reference plane c, and a low beam height marking line a and a high beam height marking line b are arranged on the marking surface of the detection board; there is a set distance L between the trigger position of the in-place detection component and the marking surface of the detection board; when the vehicle is located on the reference platform c and the front end of the vehicle head is at the trigger position of the in-place detection component, when the vehicle head touches the in-place detection component, the sound and light alarm component gives out a sound and light reminder, and the driver immediately stops the vehicle, turns on the lights, switches between low beam and high beam, and observes the deviation between the position where the light hits the detection board and the low beam height marking line a and the high beam height marking line b, and intuitively judges whether the low beam and high beam heights of the current vehicle meet the requirements.

[0004] However, the above lighting detection device still has the following problems in the actual use process:

[0005] When detecting the vehicle lighting, the driver needs to drive the vehicle onto the detection platform. When the vehicle head triggers the sound and light alarm component, the driver needs to stop immediately. This method requires the driver to have a high reaction ability. If the driver's reaction is a little slower, it may cause the vehicle head to exceed the set position, and then cause the change of the position where the light hits the detection board, resulting in inaccurate detection results. Content of the Utility Model

[0006] Aiming at the deficiencies of the prior art, the utility model provides a motor vehicle lighting detection device to solve the problem that when detecting the motor vehicle lighting at present, due to different driving abilities of different drivers, the vehicle cannot be accurately parked at a specific position, resulting in inaccurate detection data.

[0007] To achieve the above object, the present utility model provides the following technical solution: A motor vehicle lighting detection device includes a reference platform, a detection plate installed on the reference platform, and two infrared sensors. A support cavity is provided on the upper surface of the reference platform. The bottom surface of the support cavity is connected with a power mechanism and a plurality of support components.

The output shaft of the motor is fixedly connected to one end of the lead screw. The other end of the lead screw penetrates through one end of the moving component and is rotatably connected to the inner wall of the support cavity. The slide bar is arranged parallel to the lead screw, and both ends of the slide bar are fixedly connected to both ends of the inner wall of the support cavity respectively. The outer wall of the slide bar is connected to the other end of the moving component.

[0009] Further, the moving component includes two moving blocks. The two moving blocks are respectively sleeved on the outside of the lead screw and the slide bar.

The inner wall of one partition block is rotatably connected to the outer wall of the lead screw, and the inner wall of the other partition block is fixedly connected to the outer wall of the slide bar. And the two partition blocks respectively abut against one end of the two moving blocks.

[0011] Further, the support component includes a rotating shaft, a support roller, and two support blocks.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0024] Please refer to Figures 1 - 5 , a motor vehicle lighting detection device, including a reference platform 1, a detection plate 2 installed on the reference platform 1, and two infrared sensors 3. A support cavity 103 is opened on the upper surface of the reference platform 1. The bottom surface of the support cavity 103 is connected with a power mechanism and a plurality of support components. The other end of the power mechanism is connected with a moving component, the other end of the moving component is connected with a moving plate 4, and the length and width of the moving plate 4 are not less than the length and width of the support cavity 103.

[0025] A motor vehicle lighting detection device in the present utility model is similar in structure to the existing motor vehicle lighting detection devices, such as a motor vehicle lighting auxiliary detection device disclosed in the patent with the publication number CN221078017U. As Figures 1 to 5 shown, when the motor vehicle lighting detection device in the present utility model detects the motor vehicle lighting through the reference platform 1, the driver only needs to drive the vehicle onto the moving plate 4 (the moving plate 4 can be set to be longer and wider than a normal motor vehicle, so that as long as the motor vehicle drives onto the moving plate 4 and the vehicle itself is in a state perpendicular to the detection plate 2, even if the vehicle is not exactly located at the center position of the moving plate 4, it will not affect the detection result). Subsequently, the power mechanism is activated through an external controller (this is prior art, so it will not be described in detail). After the power mechanism is started, the moving plate 4 can be driven by the moving component to move towards the detection plate 2. After moving to the positions of the two infrared sensors 3, when the infrared sensors 3 detect the vehicle, they immediately transmit electrical signals to the external processor (this is prior art, so it will not be described in detail), and the power mechanism is immediately turned off through the external controller, thereby directly stopping the moving plate 4, and thus enabling each motor vehicle to be inspected to accurately stop at a specific position, thereby increasing the detection accuracy.

[0026] As Figure 2 and Figure 4 shown, the power mechanism includes a motor 7, a lead screw 8, and a slide bar 13. The outer wall of the motor 7 is fixedly connected to the side wall of the support cavity 103. The output shaft of the motor 7 is fixedly connected to one end of the lead screw 8. The other end of the lead screw 8 penetrates through one end of the moving component and is rotatably connected to the inner wall of the support cavity 103. The slide bar 13 is arranged parallel to the lead screw 8, and both ends of the slide bar 13 are fixedly connected to both ends of the inner wall of the support cavity 103. The outer wall of the slide bar 13 is connected to the other end of the moving component.

[0027] More specifically, when it is necessary to control the movement of the moving plate 4, only the switch of the motor 7 needs to be turned on through the external controller. After the motor 7 is started, the output shaft drives the lead screw 8 to rotate. After the lead screw 8 rotates, it can cooperate with the slide bar 13 at the other end of the support cavity 103 to drive the moving component to move together, and thus drive the moving plate 4 to move.

[0028] As Figure 3 shown, the moving component includes two moving blocks 12. The two moving blocks 12 are respectively sleeved on the outer sides of the lead screw 8 and the slide bar 13. The inner wall of one moving block 12 is threadedly connected to the outer wall of the lead screw 8, and the inner wall of the other moving block 12 is slidably connected to the outer wall of the slide bar 13.

[0029] More specifically, when the lead screw 8 rotates, the moving block 12 on the threaded surface can be driven to move, thereby driving the moving plate 4 above to move together. Since another moving block 12 is sleeved on the sliding rod 13 at the other end of the moving plate 4, the moving plate 4 will not rotate to one side.

[0030] It should be specifically noted here that the cooperation of the lead screw 8 and the sliding rod 13 is only one implementation manner. It is also possible to drive the sliding rod 13 to rotate together by the motor 7 driving the pulley (or gear) to drive the belt (or chain). At this time, the sliding rod 13 can also be set as the lead screw 8, and the specific setting is not limited.

[0031] As Figure 2 and Figure 4 shown, two partition blocks 6 are fixedly connected to the bottom surface of the support cavity 103. The two partition blocks 6 are respectively sleeved outside the lead screw 8 and the sliding rod 13. The inner wall of one partition block 6 is rotatably connected to the outer wall of the lead screw 8, and the inner wall of the other partition block 6 is fixedly connected to the outer wall of the sliding rod 13. And the two partition blocks 6 respectively abut against one end of the two moving blocks 12.

[0032] More specifically, by setting the partition block 6, firstly, it can prevent the moving block 12 from hitting the motor 7 when moving, causing damage to the motor 7. Secondly, it can increase a supporting force for the lead screw 8 and the sliding rod 13.

[0033] As Figure 2 and Figure 4 shown, the support assembly includes a rotating shaft 10, a support roller 11 and two support blocks 9. The lower ends of the two support blocks 9 are fixedly connected to the bottom surface of the support cavity 103. The rotating shaft 10 penetrates through the support roller 11 and the two support blocks 9 and is fixedly connected to the inner wall of the support roller 11. The two ends of the rotating shaft 10 are respectively rotatably connected to the inner walls of the two support blocks 9. The highest point of the support roller 11 abuts against the bottom surface of the moving plate 4.

[0034] More specifically, by setting the support assembly, multiple supporting forces can be provided below the moving plate 4, so as to prevent the moving plate 4 from deforming when a motor vehicle docks above the moving plate 4.

[0035] And since the support roller 11 is in contact with the bottom surface of the moving plate 4, and the support roller 11 rotates inside the two support blocks 9 through the rotating shaft 10, when the moving plate 4 moves, the support roller 11 can also reduce the friction force between it and the moving plate 4.

[0036] As Figure 1 、 Figure 2 and Figure 4 shown, sunken openings 101 are provided on both sides of the support cavity 103. The moving plate 4 is located in the sunken openings 101, and the outer wall of the moving plate 4 is slidably connected to the inner wall of the sunken openings 101.

[0037] More specifically, by providing the recessed opening 101 , the movable plate 4 can be accommodated to avoid occupying external space.

[0038] like Figure 1 , Figure 2 and Figure 4 As shown, openings 102 are formed on both sides of the depression 101 close to the detection plate 2 .

[0039] More specifically, by providing the opening 102, it is possible to prevent external debris from falling into the recessed opening 101 on this side, which would be inconvenient to clean (because the debris on the other side can be directly swept out from one side).

[0040] like Figure 1 and Figure 3 As shown, the upper surface of the movable plate 4 is fixedly connected with a positioning plate 5 .

[0041] More specifically, by setting the positioning plate 5, after the vehicle drives onto the moving plate 4, if the driver feels a pause (after the wheels touch the positioning plate 5), the vehicle can stop, and because of the effect of the positioning plate 5, the driver will not drive too far.

[0042] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
