The ends of the two insert rods 20 away from the movable block 3 extend to the outside of the movable block 3 and are welded with a pull block 8. A spring 19 is sleeved on the outside of the two insert rods 20. The height adjustment component two includes two fixed blocks 6 welded to the side of the support plate 2. Block 2 11, with a threaded rod 12 rotatably connected between the two fixed blocks 2 11. The bottom end of the threaded rod 12 passes through a fixed block 2 11 and is welded with a rotating block 21. The threaded rod 12 is externally threaded to a lifting block 14. Two sliders 2 are welded to the side of the lifting block 14. The side of the support plate 2 has two sliding grooves 2 13. The two sliders 2 are slidably connected in the two sliding grooves 2 13 respectively. The horizontal adjustment component includes two fixed blocks 3 23 welded to the side of the support frame 16. A threaded rod 3 22 is rotatably connected between the two fixed blocks 3 23. One end of the threaded rod 3 22 passes through a fixed block 3 23 and is welded with a rotating block 3 18. The threaded rod 3 22 is externally threaded to a threaded sleeve 15. One side of the threaded sleeve 15 is welded to one side of the lifting block 14.

[0032] A millimeter scale is provided on the side of the support plate 2, next to the movable block 3. By rotating the rotating block 5, the rotating block 5 drives the threaded rod 7 to rotate, causing the movable block 3 to rise and fall. The rise and fall of the movable block 3 drives the stereo camera 9 to rise and fall. Combined with the millimeter scale, the height of the stereo camera 9 can be adjusted. The operation is simple and the practicality is improved. A millimeter scale is provided on the upper surface of the support frame 16, and an indicator needle is provided on the upper surface of the threaded sleeve 15. The indicator needle points to the millimeter scale. By pointing the indicator needle to the millimeter scale, the horizontal movement distance of the support frame 16 can be controlled. The stereo camera 9 is electrically connected to the processing controller through a wire. The processing controller is electrically connected to the display terminal through a wire. The processing controller is located inside the display terminal. The stereo camera 9 is a Leica BLK3D stereo camera 9.
[0033] Working Principle: During use, the test stand is aligned with the battery pack of the light truck. The light sources emitted by the two laser lights 17 can be adjusted in length and size to simulate the locking guns corresponding to the two lock holes on the battery pack. The stereo camera 9 takes pictures of the battery pack on the light truck. By identifying the position of the lock holes in the pictures, since the positions of the two lock holes and their corresponding two locking guns on the battery pack are fixed and known, the Leica BLK3D stereo camera 9 combines a calibrated stereo camera 9 with electronic distance measurement technology and advanced algorithms. Based on the algorithm model built into the Leica BLK3D stereo camera 9, it can accurately calculate the distance between the current test stand and the lock hole, as well as the x, y, and z axis values of the test stand relative to the battery pack lock holes. These values are then displayed on the display terminal by the processing controller. Then, by rotating the rotating block 21, the rotating block... The second 21 drives the threaded rod 12 to rotate, causing the lifting block 14 to rise and fall. The rise and fall of the lifting block 14 causes the support frame 16 to rise and fall. Combined with the millimeter scale, the height of the laser light 17 on the support frame 16 can be adjusted. By rotating the rotating block 18, the rotating block 18 drives the threaded rod 22 to rotate, thereby causing the threaded rod 22 and the threaded sleeve 15 to move relative to each other, so that the support frame 16 moves horizontally. Combined with the millimeter scale, the horizontal position of the laser light 17 can be adjusted. The operation is simple, saves time, and improves practicality. After the position is adjusted, turn on the laser light 17 and check whether the light source of the laser light 17 is aligned with the center position of the two lock holes on the battery pack. If they are aligned, it means that the unlocking mechanism lock gun can be aligned with the lock hole, indicating that the movement value is correct. In actual battery replacement, the unlocking mechanism lock gun can be aligned and inserted into the lock hole, thereby performing the unlocking operation.
[0034] By pulling the pull block 8, the pull block 8 moves the insertion rod 20, causing the insertion rod 20 to move into the insertion hole on the stereo camera 9, so that the stereo camera 9 can be removed from the card slot 10, thereby realizing the disassembly of the stereo camera 9. The operation is simple, which facilitates the maintenance or replacement of the stereo camera 9 and improves its practicality.
