[0031] The following embodiments are described in detail, with examples illustrated in the accompanying drawings. When the following description refers to the drawings, identical numbers in different figures represent identical or similar elements unless otherwise indicated. The embodiments described in the following embodiments are not intended to represent all possible implementations consistent with the present application. They are merely examples of systems and methods consistent with certain aspects of the present application, as detailed in the claims.

[0032] Before using the testing equipment to test the illumination of vehicle headlights, it must first be parked next to the track. A support leg is installed on each side of the front of the testing equipment. When the support leg is lowered and pressed against the center of the track, the swing arm extends and the measuring probe on the swing arm is aligned with the center of the vehicle head, thus ensuring the accuracy of the subsequent test.

[0033] However, when adjusting the inspection equipment, the driver and an observer at the front of the equipment need to coordinate multiple times to adjust the position of the support legs on the track, combined with manual visual inspection to ensure that the support legs are aligned with the center of the track. This adjustment method is not only time-consuming and labor-intensive, but also has poor adjustment accuracy.

[0034] To solve the above problems, some embodiments of the present application provide a laser positioning device for a detection device. Figure 1 This is a schematic diagram of the structure of the laser positioning device for the detection equipment provided in this application, such as Figure 1 As shown, the laser positioning device includes: a fixed platform 1, a rotating platform assembly 2 and a laser assembly 3. The rotating platform assembly 2 is arranged on the top surface of the fixed platform 1, and two laser assemblies 3 are arranged on the top surface of the fixed platform 1, and the two laser assemblies 3 are respectively arranged on both sides of the fixed platform 1.

[0035] Figure 2 The schematic diagram of the structure of the laser assembly provided in this application is as follows: Figure 2 As shown, the laser assembly 3 includes a laser 31, a mounting tube 32, and a mounting bracket 33. In some embodiments, the laser 31 may be a red dot laser, which emits red light with a longer wavelength and less energy, and is therefore safer.

[0036] The mounting tube 32 is a rectangular block structure. A through hole is provided on one side of the rectangular block of the mounting tube 32. The diameter of the through hole matches the outer diameter of the laser 31. For example, the diameter of the through hole can be 1 mm larger than the outer diameter of the laser 31 so that the laser 31 can be plugged into the mounting tube 32 through this through hole. In order to avoid distinguishing the use direction of the mounting tube 32, threaded holes are provided on the four sides of the mounting tube 32 that are parallel to the axis of the laser 31. The number of threaded holes on each side can be two. The two threaded holes on each side are centered along the axis of the laser 31 and are through holes. In some embodiments, after the laser 31 is plugged into the mounting tube 32, in order to make the plugging of the laser 31 and the mounting tube 32 more stable, a top screw can be screwed into one of the sides of the mounting tube 32 where the threaded hole is provided, and the laser 31 can be tightened with the top screw.

[0037] The mounting bracket 33 is an L-shaped curved plate. One side of the mounting bracket 33 is provided with a mounting hole, allowing the mounting bracket 33 to be secured to the top surface of the fixed platform 1 through the mounting hole. In some embodiments, the mounting hole is an elongated hole, allowing the mounting position of the mounting bracket 33 to be adjusted. The other side of the mounting bracket 33 is provided with a fixing hole and an adjustment hole 34. The fixing hole is used to bolt the mounting bracket 33 to the side of the mounting tube 32 provided with a threaded hole, allowing the mounting tube 32 to be secured to the mounting bracket 33. In some embodiments, the adjustment hole 34 is a fan-shaped hole. Because the fan-shaped hole is an arc, the end and starting points of the arc form an angle, allowing for angle adjustment. After the mounting tube 32 is secured to the fixed bracket 33 through one of the threaded holes, the other threaded hole on the mounting tube 32 is aligned with the adjustment hole 34. Rotating the mounting tube 32 adjusts the angle between the mounting tube 32 and the horizontal plane, thereby adjusting the laser emission direction of the laser 31.

[0038] The fixed platform 1 is a plate-like structure. In the embodiment of the present application, there is no specific restriction on the shape of the fixed platform 1. For example, the fixed platform 1 can be rectangular or circular. In this embodiment, the fixed platform 1 is set as a rectangular plate. Two supporting legs 11 are provided on the bottom surface of the fixed platform 1. The two supporting legs 11 are symmetrically arranged on both sides of the fixed platform 1 along the width direction of the fixed platform 1. The two laser assemblies 3 on the fixed platform 1 are respectively arranged above the two supporting legs 11. In some embodiments, the installation positions of the two laser assemblies 3 can be set by the positions of the two supporting legs 11. Since the mounting hole on the side where the mounting bracket 33 is connected to the fixed platform 1 is a long hole, the center planes of the two supporting legs 11 can be made coplanar with the center planes of the two lasers 31 by adjusting the installation position of the mounting bracket 33.

[0039] like Figure 1As shown, the rotating platform assembly 2 is arranged between the two laser assemblies 3 on the fixed platform 1. The rotating platform assembly 2 includes a base 21, a rotating platform 22, a platform body 23 and a motor 24. The bottom surface of the base 21 is detachably connected to the fixed platform 1, the top of the base 21 is rotatably connected to the rotating platform 22, and the platform body 23 is detachably connected to the rotating platform 22. A connecting plate is provided at the bottom of the base 21, and the base 21 is bolted to the fixed platform 1 through the connecting plate. In some embodiments, the rotating platform 22 is a circular plate structure, and the bottom surface of the platform body 23 is bolted to the top surface of the rotating platform 22. Since the rotating platform 22 is rotatably connected to the base 21, the rotating platform 22 can rotate, thereby driving the platform body 23 to rotate.

[0040] A motor 24 is mounted on the side of the base 21 and secured to the base 21 via bolts. The shaft of the motor 24 is plugged into the interior of the base 21. Rotation of the motor 24 drives the rotating platform 22, which in turn drives the platform body 23. In some embodiments, the motor 24 is a stepper motor, which precisely controls the rotation angle of the rotating platform 22, thereby making the rotation angle of the platform body 23 more precise and enabling higher adjustment accuracy.

[0041] See again Figure 1 , two laser assemblies 3 are also provided on the top surface of the platform body 23. It can be understood that the laser positioning device provided in the embodiment of the present application includes at least four laser assemblies 3. Therefore, in order to better illustrate the laser positioning device of the present application, the two lasers 31 on the marking fixed platform 1 are respectively laser 1# and laser 2#, and the two lasers 31 on the marking platform body 23 are respectively laser 3# and laser 4#. Laser 1# and laser 3# are set on the same side, and laser 2# and laser 4# are set on the same side.

[0042] During installation, the laser emission directions of the two lasers 31 on the fixed platform 1 are opposite, facing the side away from the rotating platform assembly 2. That is, the laser emission directions of laser 1# and laser 2# are facing the outside of the fixed platform 1, so that the laser points emitted by laser 1# and laser 2# can each fall on the front and rear ends of the same track surface. The laser emission directions of the two lasers 31 on the platform body 23 are also opposite, and are respectively the same as the laser emission directions of the two lasers 31 on the fixed platform 1 on the same side. That is, the laser emission direction of laser 3# is the same as that of laser 1# on the fixed platform 1, and the laser emission direction of laser 4# is the same as that of laser 2# on the fixed platform 1, both facing the outside of the fixed platform 1, so that the laser points emitted by laser 3# and laser 4# can respectively fall on the front and rear ends of the track surface.

[0043] During installation, adjust the position of the mounting bracket 33 so that the center planes of the four lasers 31 are coplanar, that is, the center planes of laser 1#, laser 2#, laser 3# and laser 4# are coplanar. At this time, the four lasers 31 are all coplanar with the center plane of the support leg 11. Figure 3 The laser emitting circuit diagram of the laser positioning device provided in this application is as follows: Figure 3 As shown, the laser points emitted by laser 1# and laser 3# fall on the same end of the track surface, and the laser points emitted by laser 2# and laser 4# fall on the same end of the track surface. By adjusting the angle of laser 31, the landing position of the laser point emitted by laser 31 can be adjusted, and by controlling the rotation of motor 24, the landing position of laser 3# and laser 4# on the track surface can be adjusted.

[0044] The line connecting the laser points emitted by marking laser 1# and laser 2# respectively forms straight line A, and the line connecting the laser points emitted by laser 3# and laser 4# respectively forms straight line B. It can be understood that straight line A and straight line B coincide with each other. The rotating motor 24 can adjust the angle between straight line B and the center line of the track surface. The smaller the angle, in some embodiments, the setting direction of laser 3# and laser 4# is set to the width direction of the platform body 23, and the width direction of the platform body 23 where laser 3# and laser 4# are located is more parallel to the center line of the track surface. See again Figure 1 The platform body 23 is internally connected to a swing arm 4, and the measuring probe of the detection equipment is installed on the swing arm 4. Once the width direction of the platform body 23 is parallel to the center of the track surface, the platform body 23 can be positioned, and then the detection equipment can be positioned for subsequent light intensity detection.

[0045] Some embodiments of this application also provide a laser positioning method for detection equipment, which uses the laser positioning device provided in the above embodiments. Since the laser positioning device in the embodiments of this application is used in detection equipment, in this embodiment, the laser positioning device is described using a track as an example. The positioning method includes:

[0046] S10: Place the two supporting legs 11 under the fixed platform 1 of the laser positioning device on the track surface.

[0047] There are two tracks for the locomotive or motor vehicle. Select one of the tracks and place the two support legs 11 under the fixed platform 1 on the track surface. At this time, it is not necessary to consider whether the center plane of the support legs 11 coincides with or is parallel to the center line of the track. It is only necessary to ensure that both support legs 11 are on the track surface.

[0048] S20: adjusting the laser emission directions of the two lasers 31 on the fixed platform 1 respectively so that the laser points emitted by the two lasers 31 fall on the track surface.

[0049] Rotate the mounting tubes 32 of laser 1# and laser 2# respectively to adjust the laser emission directions of laser 1# and laser 2# so that the laser points emitted by laser 1# and laser 2# fall on the track surface. This step is the coarse adjustment of laser 31.

[0050] S30: adjusting the laser emission directions of the two lasers 31 on the platform body 23 respectively so that the laser points emitted by the two lasers 31 fall on the track surface.

[0051] The mounting tubes 32 of laser 3# and laser 4# are rotated respectively to adjust the laser emission directions of laser 3# and laser 4# so that the laser points emitted by laser 3# and laser 4# fall on the track surface.

[0052] S40: If the line connecting the two laser points of the two lasers 31 on the fixed platform 1 is not parallel to the center of the track surface, rotate the platform body 23 so that the line connecting the two laser points of the two lasers 31 on the platform body 23 is parallel to the center of the track surface.

[0053] If the line connecting the two laser points of lasers 1# and 2# is not parallel to the center of the track surface, then the line connecting the two laser points of lasers 3# and 4# is also not parallel to the center of the track surface. In this case, motor 24 is turned on to rotate platform body 23 by a certain angle until the line connecting the two laser points of lasers 3# and 4# is parallel to the center of the track surface. Then, motor 24 is turned off. At this point, the width direction of platform body 23 is parallel to the center of the track surface. Positioning platform body 23 can position the measuring probe of the detection equipment for subsequent illumination detection. Since the rotation angle of platform body 23 is small, the adjustment in S40 is a fine-tuning of laser 31.

[0054] If the line connecting the two laser points of laser 1# and laser 2# on the fixed platform 1 is parallel to the center of the track surface, it means that the line connecting the two laser points of laser 3# and laser 4# is parallel to the center of the track surface, that is, the width direction of the platform body 23 is parallel to the center of the track surface. At this time, by positioning the platform body 23, the measuring probe of the detection equipment can be positioned for subsequent illumination detection.

[0055] In the above steps, to improve positioning accuracy, the landing positions of the laser points emitted by the two lasers 31 on the platform body 23 should be within 5-10 mm of the landing positions of the laser points emitted by the two lasers 31 on the fixed platform 1, that is, the landing position of the laser point emitted by laser 3# should be within 5-10 mm of the landing position of the laser point emitted by laser 1#, and the landing position of the laser point emitted by laser 4# should be within 5-10 mm of the landing position of the laser point emitted by laser 2#. This allows for better comparison and observation of the landing positions of the laser points of laser 1# and laser 3#, as well as the landing positions of the laser points of laser 2# and laser 4#.

[0056] It can be seen from the above technical solution that the embodiment of the present application provides a laser positioning device and method for detection equipment, and the device includes: a fixed platform 1, a rotating platform assembly 2 and a laser assembly 3. Among them, two laser assemblies 3 are provided on the top surface of the fixed platform 1, and the two laser assemblies 3 are respectively arranged on both sides of the fixed platform 1, and the rotating platform assembly 2 is arranged between the two laser assemblies 3 on the fixed platform 1. Two laser assemblies 3 are also provided on the platform body 23 of the rotating platform assembly 2, and the laser assembly 3 includes a laser 31, and the center planes of the four lasers 31 are coplanar. When the line connecting the two laser points of the two lasers 31 on the fixed platform 1 is not parallel to the center of the track surface, the platform body 23 is controlled to rotate, and the line connecting the two laser points of the two lasers 31 on the platform body 23 is adjusted to be parallel to the center of the track surface, so that the detection equipment can be positioned. The laser positioning device provided by the present application does not require the operator to move the fixed platform back and forth multiple times to achieve positioning with the track, which can solve the problem of poor adjustment accuracy when adjusting the detection equipment.

The specific implementation methods provided above are only a few examples under the overall concept of this application and do not constitute a limitation on the scope of protection of this application. For those skilled in the art, any other implementation methods expanded based on the scheme of this application without expending creative work shall fall within the scope of protection of this application.
