[0056] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0057] See also Figure 1 On the one hand, an embodiment of the present application provides an adjustable bracket 10. In at least one application scenario, the adjustable bracket 10 is used to support a calibration device 20 and can adjust the position of the calibration device 20.

[0058] In some embodiments, the adjustable bracket 10 of the embodiment of the present application includes a fixing component 11, a column 12, an adjusting component 14 and a base 16. The fixing component 11 is used to fix the calibration device 20, the column 12 is fixedly connected to the base 16, and the adjusting component 14 includes a displacement module 141 and a rotation module 142 connected to each other, one of the displacement module 141 and the rotation module 142 is connected to the column 12, and the other is connected to the fixing component 11, the displacement module 141 is used to drive the fixing component 11 to move in at least one linear direction, and the rotation module 142 is used to drive the fixing component 11 to rotate around at least one axis.

[0059] The structural principle of the adjustable bracket 10 of the embodiment of the present application is: the base 16 and the column 12 are connected to form a structure that can support the adjustment component 14 and the fixed component 11. The adjustment component 14 is connected to the column 12 through one of the displacement module 141 and the rotation module 142, and the other is connected to the fixed component 11, so that the fixed component 11 follows the displacement module 141 to move in at least one linear direction and follows the rotation module 142 to rotate around at least one axis, so that the position of the calibration device 20 fixed by the fixed component 11 can be adjusted relative to the base 16 and the column 12.

[0060] The adjusting component 14 is connected to the fixing component 11 via the displacement module 141 or the rotation module 142, and both can enable the fixing component 11 to move in at least one linear direction and rotate around at least one axis.

[0061] It can be understood that the adjustment component 14 of the adjustable bracket 10 of the embodiment of the present application adopts a displacement module 141 and a rotation module 142, so that the calibration device 20 can be displaced and rotated respectively. Compared with the traditional bracket that can only be adjusted in the height direction, the adjustable bracket 10 of the embodiment of the present application provides more degrees of freedom for adjusting the position of the calibration device 20, and the adjustment operation is more convenient.

[0062] Please also read Figure 2 and Figure 3 For example, in a calibration application scenario, the calibration main frame 30 is placed in front of the front of the vehicle 200, and a side camera 31 is used to identify the distance measuring target 20a on the adjustable bracket 10 to complete the bracket placement and determine the position of the target 20a. The operator can adjust the position of the target 20a and align the target 20a by controlling the displacement module 141 and the rotation module 142 on the adjustable bracket 10. Further, after the placement of the adjustable bracket 10 and the determination of the position of the target 20a are completed, the target 20a can be disassembled and replaced with a laser level, and the laser line projected on the ground by the laser level is used as the placement reference line 21 of the calibration pattern. It can be understood that the embodiment of the present application adjusts the position of the target 20a first and then replaces the laser level, so that the current position of the laser level is the determined position of the target 20a, so as to ensure that the projected reference line is in the required position, that is, located on one side of the vehicle 200 and separated from the vehicle 200 by a certain distance. In addition, when the reference line 21 projected by the laser level is tilted, the operator can further control the rotating module 142 on the adjustable bracket 10 to adjust it, so as to accurately place the calibration pattern 40. It can be seen that in the calibration application scenario, the adjustable bracket 10 of the embodiment of the present application realizes the rapid adjustment of various calibration devices during the calibration process, making the arrangement of the calibration devices faster and more convenient.

[0093] Please review Fig.10 and Fig.11In some embodiments, the first rotating unit 1421 and the second rotating unit 1422 adopt the same structure. Taking the first rotating unit 1421 as an example, the first rotating unit 1421 includes a third fixed member 14212, a third movable member 14213 and a worm 14214. The worm 14214 is connected to the third fixed member 14212 and can rotate relative to the third fixed member 14212. The rotation axis of the worm 14214 is perpendicular to the first axis. The third fixed member 14212 includes an arc track 142122, and the central axis of the arc track 142122 overlaps the first axis. The third movable member 14213 includes a turbine tooth segment and a guide portion 142133. The guide portion 142133 is accommodated in the arc track 142122. The first arc rack 142131 is meshed with the worm 14214. When the first arc rack 142131 is subjected to the force of the worm 14214, the guide portion 142133 moves under the guidance of the arc track 142122, so that the first arc rack 142131 can drive the third movable member 14213 to rotate around the first axis relative to the third fixed member 14212. In one embodiment, the outer contour of the third rotating unit 1423 is a cylinder. The third rotating unit 1423 can be configured with a corresponding rotating structure so that the third axis overlaps with the central axis of its own outer contour, so that the third rotating unit 1423 rotates around the central axis of its own outer contour. The specific structure of the third rotating unit 1423 can be set according to actual needs and is not limited here.

[0094] See also Fig.12 In other embodiments, taking the first rotating unit 1421 as an example, the first rotating unit 1421 includes a third fixed member 14212 and a third movable member 14213, the third fixed member 14212 is installed on the second moving portion 14131, the third fixed member 14212 includes a third gear 142121, the third movable member 14213 includes a second arc-shaped rack 142132, and the third movable member 14213 rotates around the first axis relative to the third fixed member 14212 through the engagement of the second arc-shaped rack 142132 with the third gear 142121.

[0095] Exemplarily, the third fixing member 14212 also includes a knob that can drive the third gear 142121 to rotate, and an anti-detachment structure is provided between the third fixing member 14212 and the third movable member 14213 to prevent the third fixing member 14212 and the third movable member 14213 from detaching from each other. In another exemplary embodiment, the anti-slip structure is configured as follows: the third fixed member 14212 also includes an arc track 142122 that can be coaxially arranged with the second arc rack 142132, the third movable member 14213 includes a guide portion 142133 that cooperates with the arc track 142122, the guide portion 142133 is received in the arc track 142122, and is limited by the arc track 142122, so that when the third gear 142121 drives the second arc rack 142132 to rotate around the axis of the second arc rack 142132, the guide portion 142133 can only move in the arc track 142122, thereby preventing the third movable member 14213 from being separated from the third fixed member 14212. The specific structures of the second rotating unit 1422 and the third rotating unit 1423 can be configured with reference to the first rotating unit 1421 and actual needs, and will not be described in detail here.

[0096] Please also read Fig.11 , Fig.13 and Fig.14 In other embodiments, at least one of the first rotating unit 1421, the second rotating unit 1422, and the third rotating unit 1423 is provided with a screw slider mechanism. Exemplarily, the first rotating unit 1421 and the second rotating unit 1422 adopt the same structure. Taking the first rotating unit 1421 as an example, the first rotating unit 1421 includes a third fixed member 14212, a third movable member 14213, a screw 14215, and a slider 14216. The third fixed member 14212 is installed on the second moving part 14131. Among them, the third fixed member 14212 includes an arc track 142122, and the arc track 142122 takes the first axis as the central axis. The third movable member 14213 includes a guide portion 142133 matched with the arc track 142122, and the guide portion 142133 is received in the arc track 142122 and is limited by the arc track 142122. The screw rod 14215 and the slider 14216 are mounted on the third fixing member 14212. The screw rod 14215 and the slider 14216 are connected in cooperation. When the screw rod 14215 rotates relative to the third fixing member 14212, the slider 14216 can be driven to slide in the length direction of the screw rod 14215. The third movable member 14213 includes a connecting portion 142134. When the third fixing member 14212 and the third movable member 14213 are connected, the connecting portion 142134 is connected to the slider 14216, and the connecting portion 142134 moves with the slider 14216, and the third movable member 14213 is rotated around the first axis under the guidance of the arc track 142122.

[0097] The slider 14216 includes a driving column 142161, the axis direction of which is parallel to the central axis of the arc track 142122 and perpendicular to the central axis of the screw rod 14215. The connecting portion 142134 is provided with a receiving hole 142135 for receiving the driving column 142161. The size of the receiving hole 142135 has a margin. For example, the receiving hole 142135 is an elliptical hole or a bar hole. The area of ​​the receiving hole 142135 receiving the driving column 142161 will change with the movement of the third movable member 14213. The driving column 142161 is used to push the connecting portion 142134 when the slider 14216 moves, so that the third movable member 14213 rotates around the first axis without interfering with the moving stroke of the connecting portion 142134.

[0098] In other embodiments, two of the first rotating unit 1421, the second rotating unit 1422, and the third rotating unit 1423 adopt an angular displacement swing table, and the other adopts a rotating table, and rotation adjustment on three mutually perpendicular rotation axes is achieved through a combined connection. The specific settings can be referred to.

[0099] In some embodiments, each rotating unit may be configured with a locking mechanism, for example, each rotating unit locks the corresponding rotating part through the corresponding locking mechanism, so that each rotating unit is fixed to each other. Alternatively, each rotating unit is locked through a common locking mechanism, for example, the rotating parts of each rotating unit are locked at the same time by the same locking mechanism, so that each rotating unit is fixed to each other. Taking the first rotating unit 1421 as an example, the locking mechanism may use a brake pad, and the brake pad is arranged on the third fixed member 14212. When locking, the brake pad is driven to press against the contact surface of the third movable member 14213, so as to achieve the locking of the third movable member 14213 through the friction force of the brake pad. The locking mechanism may also use a fixed toothed disc, for example, a fixed toothed disc is arranged on the third fixed member 14212, and the fixed toothed disc is a gear structure that can mesh with the second arc-shaped rack 142132, but cannot mesh with the second arc-shaped rack 142132 to rotate relative to each other. When the second arc-shaped rack 142132 is driven to rotate, the fixed gear plate moves away from the second arc-shaped rack 142132, and the second arc-shaped rack 142132 is driven to rotate by the third gear 142121; when the second arc-shaped rack 142132 is locked, the fixed gear plate is driven to engage with the second arc-shaped rack 142132. Since the fixed gear plate cannot engage with the second arc-shaped rack 142132 and rotate relative to it, the second arc-shaped rack 142132 is locked, and the third movable member 14213 and the third fixed member 14212 are relatively fixed.

[0100] In other embodiments, the rotation module 142 may also adopt an existing three-dimensional panoramic gear head, which is a photography auxiliary adjustment device that can be rotated and adjusted on three mutually perpendicular axes.
