Description

TECHNICAL FIELD

[0001] The utility model relates to a bearing sliding table for ADAS calibration. BACKGROUND

[0002] The sensors in the automobile ADAS system need to be calibrated after the vehicle has an accident or is repaired to ensure that the sensors can work normally. When calibrating the camera in the ADAS system, the calibration instrument needs to be placed in front of the vehicle, the board of the calibration instrument faces the ADAS sensor, and the camera and the board of the calibration instrument are strictly perpendicular, as shown in FIG. Figure 1

[0003] To ensure the perpendicularity between the camera and the instrument, the existing solution is to adjust the foot cups at the bottom of the calibration instrument to change the pitch angle of the board. However, since there are many foot cups, adjusting one foot cup will cause the pitch angle to change, making it difficult to achieve accurate adjustment. At the same time, the adjustment needs to be done by bending over, and after adjustment, it is necessary to stand up again to measure, which is low in efficiency. UTILITY MODEL CONTENTS

[0037] The technical scheme of the utility model will be described in detail below with reference to the drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0038] As Figure 2and Figure 8 A support slide for ADAS calibration includes a base plate and a mounting plate 1. A pulley is mounted on the back side of the base plate, the pulley being used for sliding engagement with a crossbeam 8 of the ADAS calibration system.

[0039] Specifically, such as Figure 2 , Figure 7 As shown, the substrate includes an upper substrate 3, a lower substrate 10, and two insertion rods 9. One end of each insertion rod 9 is fixedly connected to a first optical aperture in the upper substrate 3 or the lower substrate 10 by an interference fit, and the other end is slidably connected to a second optical aperture in the lower substrate 10 or the upper substrate 3, so as to realize the vertical movement of the lower substrate 10 relative to the upper substrate 3.

[0040] like Figure 2 , Figure 6 and Figure 9 The pulleys include two upper pulleys 17 mounted on the upper base plate 3 and two lower pulleys 14 mounted on the lower base plate 10.

[0041] Specifically, a fixing plate 6 is connected to the back side of the upper base plate 3. The fixing plate 6 has an opening on the side near the upper base plate 3. The upper pulley 17 is installed at the opening. One end of the rotating shaft connected to the upper pulley 17 is connected to the fixing plate 6, and the other end is connected to the upper base plate 3. The upper pulley 17 contacts and engages with the top surface of the crossbeam 8. The annular protrusion on the upper pulley 17 engages with the slide rail on the top surface of the crossbeam 8, which serves as a limiting function.

[0042] The lower roller 14 engages with the slide rail on the front side of the crossbeam 8. The lower roller 14 has an annular groove in the middle, which divides the roller body into front and rear parts. The rear part of the roller body is located in the corresponding slide rail, and the annular groove engages with the front edge of the slide rail to limit its movement.

[0043] When the substrate moves along the crossbeam 8, if it encounters an obstacle caused by manufacturing error, the upper substrate 3 and the lower substrate 10 will float adaptively under the action of the pulley, thereby ensuring smooth movement.

[0044] The support slide also includes a locking mechanism for fixing its position. For example... Figure 2 , Figure 4 , Figure 6 and Figure 9 The locking mechanism includes a locking handle 4 mounted on a fixed plate 6 via bearings. A locking block 7 is fixedly connected to the lower end of the locking handle 4, and the locking block 7 is located in a slide rail at the top of the crossbeam 8. Figure 5The locking block 7 is longer than its width, and has inclined surfaces for contacting and engaging with the corresponding slide rail. During movement, the length of the locking block 7 is parallel to the slide rail. After rotating the locking handle 4 90 degrees, its length becomes perpendicular to the slide rail, and the inclined surfaces at both ends contact and press against the inclined surfaces in the slide rail, thus fixing its position. Furthermore, the locking handle 4 has external threads, at which a second locking nut 5 is installed. Rotating the second locking nut 5 to make it press against the fixing plate 6 fixes the angle of the locking handle 4.

[0045] Furthermore, the fixing plate 6 is provided with a position pointer 18, which is used to point to the scale on the crossbeam to indicate the current position.

[0046] like Figure 2 The mounting plate 1 is located on the front side of the substrate. The top of the mounting plate 1 is rotatably connected to the top of the upper substrate 3 via a pivot, so as to realize the pitch rotation of the mounting plate 1 relative to the substrate. The front part of the mounting plate 1 is provided with two mounting shafts 2, the size of which corresponds to the standard hole spacing on the back of the plate.

[0047] like Figure 2 and 3 The bearing slide also includes an elevation adjustment handle 11, a threaded sleeve 15, a spherical bearing 16, and a ball bearing 13.

[0048] The spherical bearing 16 is mounted on the lower base plate 10, and the threaded sleeve 15 is installed in the inner hole of the spherical bearing 16. The threaded rod of the elevation adjustment handle 11 passes through the threaded hole of the threaded sleeve 15 from back to front and engages with the threaded hole. The front end of the elevation adjustment handle 11 is ball-connected to the mounting plate 1 through the ball bearing 13. When the elevation adjustment handle 11 is rotated, the front end of the elevation adjustment handle 11 extends or retracts relative to the lower base plate 10, thereby driving the mounting plate 1 to rotate in pitch relative to the base plate, completing the precise adjustment of the pitch angle until the perpendicularity requirement between the camera and the plate surface is met.

[0049] Furthermore, a first locking nut 12 is also installed on the threaded rod of the elevation adjustment handle 11. When the first locking nut 12 is tightened to fit against the threaded sleeve 15, the elevation angle can be fixed.

[0050] During operation, first open the locking mechanism, then adjust the position of the entire load-bearing slide along the crossbeam 8 so that the plate hanging on the mounting plate 1 is located in the center front of the vehicle. Then operate the locking mechanism to fix the position of the entire load-bearing slide and tighten the second locking nut 5. Next, rotate the elevation adjustment handle 11 until the camera is perpendicular to the plate surface, and finally tighten the first locking nut 12. At this point, the horizontal position and elevation angle of the instrument plate surface meet the requirements, and the calibration work can begin normally.

[0051] It should be noted that, as will be apparent to those skilled in the art, this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. The scope of this utility model is defined by the claims rather than the foregoing description.
