[0024] The present invention will now be described in detail with reference to the accompanying drawings:

[0025] In one embodiment of this utility model, an ADAS calibration fixture is disclosed, with reference to Figure 1-4 As shown, it is a simple ADAS calibration frame, including a base 1, a placement plate 2, and a connecting seat 3; the placement plate 2 is placed above the base 1, and the connecting seat 3 is placed above the placement plate 2; the outer side of the base 1 is provided with a spiral structure to facilitate the adjustment of the height of the calibration frame, and a telescopic structure is provided between the placement plate 2 and the base 1 to facilitate fine adjustment of the height of the placement plate 2; the two sides of the connecting seat 3 are provided with a sliding structure to facilitate the horizontal movement of the target plate 31.

[0026] Specifically, in this embodiment, four side plates 11 are symmetrically arranged on the outer walls of both sides of the base 1, located near the endpoints on both sides of the base 1. Each side plate 11 is equipped with a spiral cylinder 12, the two ends of which extend to the outside of the side plate 11 and are threadedly connected to a threaded rod 13. A handwheel 14 is installed at the top of the threaded rod 13, and a roller 15 is rotatably connected to the bottom. The spiral structure described above is formed by the spiral cylinder 12, the threaded rod 13, the handwheel 14, and the roller 15.

[0027] During use, by turning the handwheel 14, the threaded rod 13 is rotated inside the screw cylinder 12 and slides downward, causing the threaded rod 13 to drive the roller 15 to move downward in sync. At this time, the distance between the base 1 and the ground is increased, so that the calibration frame can slide on uneven surfaces, thereby facilitating transportation.

[0028] In this embodiment, the aforementioned shelf 2 is mounted on the top of the base 1 via a lifting mechanism. The lifting mechanism includes telescopic columns 4 symmetrically mounted on both sides of the top of the base 1. The top of each telescopic column 4 is fixedly connected to the bottom of the shelf 2. The telescopic column 4 can be a hydraulic, pneumatic, or mechanical telescopic rod. Additionally, a lower lead screw 16 is located at the center of the top of the base 1, and an upper lead screw 21 is located at the corresponding position on the bottom of the shelf 2. The lower lead screw 16 and the upper lead screw 21 are coaxially arranged. Both ends of the lower lead screw 16 and the upper lead screw 21 are locked with nuts 8, which are located on the side closest to the base 1 and the shelf 2, respectively. Operating handles 81 are symmetrically arranged on the outer wall of each nut 8. These operating handles 81 can be configured as rotary handles as needed. The telescopic structure described above is constituted by the telescopic columns 4, the upper lead screw 21, the lower lead screw 16, the nuts 8, and the operating handles 81.

[0029] During use, the telescopic function of the telescopic column 4 is used to limit the lifting range of the shelf 2. The nut 8 is positioned by the upper screw 21 and the lower screw 16, and is adjusted by the operating handle 81 on the outer wall of the nut 8. Specifically, rotating the operating handle 81 causes the nut 8 to slide inward on the outer wall of the lower screw 16 and the upper screw 21, so as to adjust the height of the shelf 2.

[0030] In this embodiment, the aforementioned connecting seat 3 is installed on the top of the shelf 2 via a detachable fastening structure, and a laser 5 is installed at the center of the surface of the connecting seat 3. Specifically, the detachable fastening structure includes a concave fastening frame 6 located at the center of the top of the shelf 2, and a convex fastening block 7 embedded therein. The top of the convex fastening block 7 is fixedly connected to the bottom of the connecting seat 3. Further, locking bolts 61 are provided on the outer walls of both sides of the concave fastening frame 6, and threaded holes 71 matching the locking bolts 61 are provided on both sides of the bottom of the convex fastening block 7. The locking bolts 61 penetrate the concave fastening frame 6 and are threadedly connected to the threaded holes 71.

[0031] During use, by rotating the locking bolt 61, one end of it is screwed out to the outside of the threaded hole 71, which facilitates the loosening of the convex fastening block 7. Then, by pulling the connecting seat 3, the lower end of the convex fastening block 7 is slid to the outside of the concave fastening frame 6, and the connecting seat 3 can be removed from the top of the shelf 2 for disassembly and maintenance of the calibration frame, thereby improving the convenience of using the calibration frame.

[0032] In this embodiment, the connecting seat 3 has symmetrically arranged horizontal plates 32 on both outer walls. Each horizontal plate 32 has a transverse guide groove 33 inside. One end of the guide groove 33 extends to the outside of one side of the horizontal plate 32, and a guide block 34 is slidably connected inside it. One end of the guide block 34 extends out of the guide groove 33 and is equipped with a horizontally adjustable target plate 31. The horizontal plates 32, guide grooves 33, and guide blocks 34 constitute the sliding structure described above.

[0033] The above describes an ADAS calibration frame. In use, by manually rotating the handwheel 14, the threaded rod 13 drives the roller 15 to move synchronously, thereby changing the distance between the base 1 and the ground, thus efficiently transferring the ADAS calibration frame. By manually rotating the operating handle 81, the nut 8 slides inward on the outer wall of the lower threaded rod 16 and the upper threaded rod 21. After the height of the placement plate 2 is limited by the telescopic column 4, the height of the connecting seat 3 is adjusted. Then, by pulling the target plate 31 laterally, one end of the guide block 34 slides within the guide groove 33, thus adjusting the horizontal position of the target plate 31 for accurate calibration of the vehicle's ADAS system. When the calibration frame needs to be inspected and maintained, the locking bolt 61 is rotated so that one end is screwed out to the outside of the threaded hole 71. The connecting seat 3 is then pulled back so that the lower end of the convex fastening block 7 slides to the outside of the concave fastening frame 6. The connecting seat 3 can then be removed from the shelf 2, thus completing the use and disassembly of the calibration frame.

[0034] The calibration frame of the present invention is disclosed through the above embodiments. Compared with the prior art, the present invention has the following advantages:

[0035] 1. This utility model, through the combination of a spiral structure and a telescopic structure, is simple to operate, facilitates the adjustment of the height of the connecting seat as needed, and improves the calibration accuracy when using the calibration frame;

[0036] 2. This utility model facilitates the adjustment of the horizontal position of the target plate through the cooperation of the guide groove and the guide block;

[0037] 3. This utility model, through the cooperation of the convex fastening block and the concave fastening frame, allows for disassembly and maintenance according to actual needs, improving the convenience of using the calibration frame;

[0038] 4. This utility model not only achieves the purpose of facilitating transportation, but also improves the calibration accuracy and convenience during use, and has strong practical value.

[0039] The above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
