Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0056] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention.

[0057] Please refer to Figure 1. In one aspect, this application provides an adjustable bracket 10. In at least one application scenario, the adjustable bracket 10 is used to support the calibration device 20 and can adjust the position of the calibration device 20.

[0058] In some embodiments, the adjustable bracket 10 of this 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. 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 in this embodiment is as follows: after the base 16 and the column 12 are connected, a structure that can support the adjustment component 14 and the fixing component 11 is formed. 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 fixing component 11, so that the fixing component 11 moves with the displacement module 141 in at least one linear direction and rotates with the rotation module 142 around at least one axis, so that the position of the calibration device 20 fixed by the fixing component 11 can be adjusted relative to the base 16 and the column 12.

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

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

[0062] Please refer to Figures 2 and 3 together. For example, in one calibration application scenario, the calibration main frame 30 is placed in front of the vehicle 200. A camera 31 on one side identifies the ranging 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 and align the target 20a by controlling the displacement module 141 and rotation module 142 on the adjustable bracket 10. Furthermore, after completing the placement of the adjustable bracket 10 and determining the position of the target 20a, the target 20a can be disassembled and replaced with a laser level. The laser line projected onto the ground by the laser level serves as the reference line 21 for the calibration pattern. It is understood that this embodiment adjusts the position of the target 20a first and then replaces the laser level, ensuring that the current position of the laser level is the determined position of the target 20a, thus guaranteeing that the projected reference line is in the required position, i.e., located on one side of the vehicle 200 and at a certain distance from the vehicle 200. Furthermore, when the reference line 21 projected by the laser level is tilted, the operator can further control the rotation module 142 on the adjustable bracket 10 to straighten it, thereby facilitating the accurate placement of the calibration pattern 40. It is evident that, in calibration application scenarios, the adjustable bracket 10 of this embodiment enables rapid adjustment of various calibration devices during the calibration process, making the placement of calibration devices faster and more convenient.

[0063] Referring to Figure 4, in some embodiments, the fixing component 11 includes a first connector 111 and a second connector 112. The first connector 111 is connected to the adjusting component 14, and a first positioning part 1111 is provided on the first connector 1111. The second connector 112 is detachably connected to the first connector 111, and a second positioning part 1121 is provided on the second connector 1121 for use in conjunction with the first positioning part 1111. The first positioning part 1111 and the second positioning part 1121 are connected in conjunction, and the second connector 112 is used to fix the calibration device 20.

[0064] Understandably, in this embodiment of the application, the first connector 111 is connected to the adjustment component 14, and the second connector 112 is used to fix the calibration device 20, so that the first connector 111 and the second connector 112 are detachably connected, thereby realizing the quick installation and replacement of the calibration device 20.

[0065] In some embodiments, the first connector 111 and the second connector 112 are detachably connected by at least one of the following methods: magnetic connection, snap-fit ​​connection, bolt and nut connection. For example, one of the first connector 111 and the second connector 112 is provided with a magnetic element, and the other is a magnetically oriented metal structure. Further, one of the first connector 111 and the second connector 112 is provided with a positioning pin, and the other is provided with a positioning hole that engages with the positioning pin, so that the first connector 111 and the second connector 112 are mutually positioned when connected.

[0066] Please refer to Figure 5. In some embodiments, the base 16 includes a first connecting rod 161 and a second connecting rod 162. The first connecting rod 161 is vertically connected to the middle of the second connecting rod 162, and the column 12 is connected to the first connecting rod 161.

[0067] It is understood that the first connecting rod 161 and the second connecting rod 162 of the base 16 in this embodiment of the application are interconnected and form a T-shaped structure, which helps to ensure the stability of the main structure of the support.

[0068] In some embodiments, the adjustable bracket 10 further includes a rib plate 15, which includes a first support surface and a second support surface that are perpendicular to each other. The first support surface abuts against the upper end surface of the base 16, and the second support surface abuts against the bottom outer peripheral surface of the column 12.

[0069] Understandably, in order to improve the structural stability of the column 12, this embodiment of the application provides a rib plate 15 between the base 16 and the column 12 to better connect the base 16 and the column 12, and to prevent the column 12 from tipping over due to imbalance of the center of gravity when supporting the adjustment component 14, the fixing component 11 and the calibration device 20.

[0070] In some embodiments, the base 16 further includes a first T-shaped structural member 163 and a second T-shaped structural member 164 that cooperate with each other. The first T-shaped structural member 163 and the second T-shaped structural member 164 are disposed opposite to each other. Each of the first T-shaped structural member 163 and the second T-shaped structural member 164 includes a horizontal portion and a vertical portion that are connected to each other. The first connecting rod 161 abuts vertically against the middle portion of the second connecting rod 162. The first connecting rod 161 is disposed between the vertical portion of the first T-shaped structural member 163 and the vertical portion of the second T-shaped structural member 164. The second connecting rod 162 is disposed between the horizontal portion of the first T-shaped structural member 163 and the horizontal portion of the second T-shaped structural member 164. The first T-shaped structural member 163 has a threaded hole on its end face facing the second T-shaped structural member 164. The first connecting rod 161 and the second connecting rod 162 are provided with screws and mounting holes that align with the threaded holes. The screws pass through the mounting holes and the threaded holes in sequence, so that the first T-shaped structural member 163 and the second T-shaped structural member 164 clamp and lock the first connecting rod 161 and the second connecting rod 162. Exemplarily, the rib plate 15 is provided on the first T-shaped structural member 163, and the first supporting surface abuts against the upper end face of the first T-shaped structural member 163.

[0071] In some embodiments, the first connecting rod 161 and the second connecting rod 162 are made of hollow aluminum square tubes, and foot pads are respectively installed on the end of the first connecting rod 161 away from the second connecting rod 162 and the two ends of the second connecting rod 162.

[0072] Please refer to Figure 6. In some embodiments, the rotation module 142 is connected to the fixing component 11, and the displacement module 141 includes a first displacement unit 1411, a second displacement unit 1412, and a third displacement unit 1413.

[0073] The first displacement unit 1411 is connected to the column 12 and can move along the height direction of the column 12. The second displacement unit 1412 is connected to the first displacement unit 1411 and has a first moving part 14121. The first moving part 14121 can move relative to the first displacement unit 1411 in a first linear direction, which is perpendicular to the height direction of the column 12. The second displacement unit 1412 follows the first displacement unit 1411 in the height direction of the column 12. The third displacement unit 1413 is connected to the first moving part 14121 and has a second moving part 14131. The second moving part 14131 is connected to the rotation module 142 and can drive the rotation module 142 to move relative to the second displacement unit 1412 in a second linear direction, which is perpendicular to both the height direction of the column 12 and the first linear direction. The third displacement unit 1413 follows the first moving part 14121 in the first linear direction.

[0074] Understandably, the displacement module 141 in this embodiment of the application is provided with a first displacement unit 1411, a second displacement unit 1412 and a third displacement unit 1413. The first displacement unit 1411 drives the second displacement unit 1412 to move in the height direction of the column 12. The second displacement unit 1412 can drive the third displacement unit 1413 to move relative to the first displacement unit 1411 in the first straight line direction. The third displacement unit 1413 can drive the rotation module 142 to move relative to the second displacement unit 1412 in the second straight line direction, thereby realizing the displacement adjustment of the calibration device 20 in three mutually perpendicular directions.

[0075] Referring to Figure 7, in some embodiments, the first displacement unit 1411 includes a slider 14111 and a first locking member 14112. The slider 14111 is connected to the column 12 and can slide relative to the column 12 in the height direction of the column 12. The slider 14111 is provided with a first threaded through hole, one end of which faces the outer peripheral surface of the column 12, and the other end of which communicates with the outside of the slider 14111.

[0076] The first locking member 14112 includes a first brake pad 141121, a first knob 141122, and a first threaded rod 141123 that mates with a first threaded through hole. The first brake pad 141121 is disposed opposite to the first threaded through hole and is located between the sliding member 14111 and the outer peripheral surface of the column 12. One end of the first threaded rod 141123 passes through the first threaded through hole and is connected to the first brake pad 141121. The other end of the first threaded rod 141123 is connected to the first knob 141122. The first knob 141122 is located outside the sliding member 14111. The first threaded rod 141123 is used to press the first brake pad 141121 against the outer peripheral surface of the column 12 when locked.

[0077] By way of example, in this embodiment of the application, the sliding member 14111 is a sleeve fitted onto the column 12. When the first threaded rod 141123 is loosened, there is no interaction force between the first brake pad 141121 and the outer peripheral surface of the column 12, and the sliding member 14111 can slide relative to the column 12 in the height direction. When the first threaded rod 141123 is tightened, the first brake pad 141121 is pressed against the outer peripheral surface of the column 12 by the push of the first threaded rod 141123, which increases the friction between the first brake pad 141121 and the column 12, thereby locking the sliding member 14111 onto the column 12.

[0078] Please refer to Figures 7 to 9. In some embodiments, the second displacement unit 1412 includes a first fixing member 14122, a first movable member 14123, and a first adjusting member 14124. The first fixing member 14122 is connected to the sliding member 14111, and the first fixing member 14122 is provided with a first sliding groove 141221, the length direction of which is parallel to the first straight line direction.

[0079] The first movable part 14121 is disposed on the first movable member 14123. The first movable member 14123 includes a first boss 141231 that is adapted to the inner contour of the first slide groove 141221. A first rack 141232 is provided on the table surface of the first boss 141231. The length direction of the first rack 141232 is parallel to the first straight line direction. Parts of the first boss 141231 and parts of the first rack 141232 are both received in the first slide groove 141221.

[0080] The first adjusting member 14124 is mounted on the first fixing member 14122. The first adjusting member 14124 is provided with a first gear 141241 located in the first slide groove 141221. The first gear 141241 is meshed with the first rack 141232. The first adjusting member 14124 is used to drive the first gear 141241 to rotate, so that the first moving part 14121 moves relative to the first fixing member 14122 in the first linear direction.

[0081] In one embodiment, a second threaded through hole extending to the outside is provided on one side wall of the first groove 141221. The second displacement unit 1412 further includes a second locking member 14125, which includes a second brake pad, a second knob, and a second threaded rod that mates with the second threaded through hole. The second brake pad faces the second threaded through hole and is located between the side wall of the first groove 141221 and the side wall of the first boss 141231. One end of the second threaded rod passes through the second threaded through hole and is connected to the second brake pad. The other end of the second threaded rod is connected to the second knob, which is located outside the first fixing member 14122. The second threaded rod is used to press the second brake pad against the side wall of the first boss 141231 when locked.

[0082] Understandably, in this embodiment, the second displacement unit 1412 moves the calibration device 20 in the first linear direction via a gear and rack meshing mechanism. Simultaneously, a second locking member 14125 is configured to lock the device in place. When the second threaded rod is loosened, there is no interaction force between the second brake pad and the side wall of the second boss 141331, allowing the first movable member 14123 to move relative to the first fixed member 14122 in the first linear direction. When the second threaded rod is tightened, the friction between the second brake pad and the side wall of the second boss 141331 increases, thereby locking the first movable member 14123 onto the first fixed member 14122.

[0083] In some embodiments, the third displacement unit 1413 includes a second movable member 14132, a second fixed member 14133, and a second adjusting member 14134. The second moving part 14131 is disposed on the second movable member 14132, and the second movable member 14132 is provided with a second sliding groove 141321, the length direction of the second sliding groove 141321 being parallel to the second straight line direction.

[0084] The second fixing member 14133 is connected to the first moving part 14121. The second fixing member 14133 includes a second boss 141331 that matches the inner contour of the second slide groove 141321. A second rack 141332 is provided on the platform of the second boss 141331. The length direction of the second rack 141332 is parallel to the second straight line direction. Parts of the second boss 141331 and the second rack 141332 are both received in the second slide groove 141321. The second adjusting member 14134 is mounted on the second moving part 14132. The second adjusting member 14134 is provided with a second gear 141341 located in the second slide groove 141321. The second gear 141341 meshes with the second rack 141332. The second adjusting member 14134 is used to drive the second gear 141341 to rotate, so that the second moving part 14131 moves relative to the second fixing member 14133 in the second straight line direction.

[0085] Please refer to Figure 8 again. In one embodiment, a third threaded through hole extending to the outside is provided on one side wall of the second slide groove 141321. The third displacement unit 1413 also includes a third locking member 14135, which includes a third brake pad 141351, a third knob 141352, and a third threaded rod 141353 that cooperates with the third threaded through hole. The third brake pad 141351 is directly opposite the third threaded through hole and is located between the side wall of the second slide groove 141321 and the side wall of the second boss 141331. One end of the third threaded rod 141353 passes through the third threaded through hole and is connected to the third brake pad 141351. The other end of the third threaded rod 141353 is connected to the third knob 141352. The third knob 141352 is located outside the second fixing member 14133. The third threaded rod 141353 is used to make the third brake pad 141351 press against the side wall of the second boss 141331 when locked.

[0086] Understandably, in this embodiment, the third displacement unit 1413 moves the calibration device 20 in the second linear direction via a gear and rack meshing mechanism. Simultaneously, a third locking member 14135 is configured for locking. When the third threaded rod 141353 is loosened, there is no interaction force between the third brake pad 141351 and the sidewall of the second boss 141331, allowing the second movable member 14132 to move relative to the second fixed member 14133 in the second linear direction. When the third threaded rod 141353 is tightened, the friction between the third brake pad 141351 and the sidewall of the second boss 141331 increases, thereby locking the second movable member 14132 securely to the second fixed member 14133.

[0087] In other embodiments, both the first displacement unit 1411 and the second displacement unit 1412 adopt existing dovetail slides, that is, the structure of the first slide 141221 and the second slide 141321 are both dovetail grooves, and the first boss 141231 and the second boss 141331 are bosses that adapt to the inner contour of the dovetail groove. When it is necessary to disassemble the fixed part and the movable part, the movable part can only be moved relative to the fixed part in the length direction of the dovetail groove until it is disengaged. The adaptive connection between the dovetail groove and the boss can prevent the fixed part and the movable part from disengaging from each other in actual use.

[0088] Please refer to Figures 6 and 11 together. In some embodiments, the rotation module 142 includes a first rotation unit 1421, a second rotation unit 1422, and a third rotation unit 1423.

[0089] The first rotating unit 1421 is connected to the second moving part 14131. The first rotating unit 1421 has a first rotating part 14211, which can rotate relative to the second moving part 14131 about a first axis. The first rotating unit 1421 is used to follow the second moving part 14131 as it moves in a second linear direction. The second rotating unit 1422 is connected to the first rotating part 14211. The second rotating unit 1422 has a second rotating part, which can rotate relative to the first rotating unit 1421 about a second axis. The second axis is perpendicular to the first axis. The second rotating unit 1422 is used to follow the first rotating part 14211 as it rotates about the first axis.

[0090] The third rotating unit 1423 is connected to the second rotating part. The third rotating unit 1423 is provided with a third rotating part. The third rotating part is connected to the fixing component 11. The third rotating part can drive the fixing component 11 to rotate relative to the second rotating unit 1422 around the third axis. The third axis is perpendicular to the first axis and the second axis respectively. The third rotating unit 1423 is used to follow the second moving part 14131 to rotate around the second axis.

[0091] It is understood that the rotation module 142 in this embodiment of the application is provided with a first rotation unit 1421, a second rotation unit 1422 and a third rotation unit 1423 respectively. The first rotation unit 1421 can drive the second rotation unit 1422 to rotate around the first axis, the second rotation unit 1422 can drive the third rotation unit 1423 to rotate around the second axis, and the third rotation unit 1423 can drive the fixed component 11 to rotate around the third axis, thereby realizing the rotation adjustment of the calibration device 20 on three mutually perpendicular rotation axes.

[0092] In some embodiments, at least one of the first rotating unit 1421, the second rotating unit 1422, and the third rotating unit 1423 is provided with an arc-shaped rack and a gear (or worm gear) that mesh with each other. The arc-shaped rack of the rotating unit is connected to the corresponding rotating part. When the gear drives the arc-shaped rack to rotate, the arc-shaped rack drives the corresponding rotating part to rotate.

[0093] Please review Figures 10 and 11 together. In 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 gear 14214. The worm gear 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 gear 14214 is perpendicular to the first axis. The third fixed member 14212 includes an arc-shaped track 142122, and the central axis of the arc-shaped track 142122 overlaps with the first axis. The third movable component 14213 includes a turbine tooth segment and a guide portion 142133. The guide portion 142133 is housed within an arc-shaped track 142122. The first arc-shaped rack 142131 meshes with the worm gear 14214. When the first arc-shaped rack 142131 is subjected to the force of the worm gear 14214, the guide portion 142133 moves under the guidance of the arc-shaped track 142122, allowing the first arc-shaped rack 142131 to drive the third movable component 14213 to rotate relative to the third fixed component 14212 around the first axis. In one embodiment, the outer contour of the third rotating unit 1423 is cylindrical. 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, thereby causing the third rotating unit 1423 to rotate 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] Please refer to Figure 12. In some 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 mounted on the second moving part 14131. The third fixed member 14212 includes a third gear 142121. The third movable member 14213 includes a second arc-shaped rack 142132. The third movable member 14213 rotates relative to the third fixed member 14212 about a first axis through the meshing of the second arc-shaped rack 142132 and the third gear 142121.

[0095] For example, 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. For example, the anti-detachment structure is configured such that the third fixing member 14212 further includes an arc-shaped track 142122 coaxially arranged with the second arc-shaped rack 142132, and the third movable member 14213 includes a guide portion 142133 cooperating with the arc-shaped track 142122. The guide portion 142133 is housed within the arc-shaped track 142122 and is limited by the arc-shaped track 142122, so that when the third gear 142121 drives the second arc-shaped rack 142132 to rotate around the axis of the second arc-shaped rack 142132, the guide portion 142133 can only move within the arc-shaped track 142122, thereby preventing the third movable member 14213 from detaching from the third fixing member 14212. The specific structures of the second rotating unit 1422 and the third rotating unit 1423 can be set with reference to the first rotating unit 1421 and actual needs, and will not be described in detail here.

[0096] Please refer to Figures 11, 13, and 14 together. In some 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 lead screw and 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 fixing member 14212, a third moving member 14213, a lead screw 14215, and a slider 14216. The third fixing member 14212 is mounted on the second moving part 14131. The third fixing member 14212 includes an arc-shaped track 142122, which is centered on the first axis. The third movable member 14213 includes a guide portion 142133 that cooperates with the arc-shaped track 142122. The guide portion 142133 is housed within the arc-shaped track 142122 and is limited by the arc-shaped track 142122. The lead screw 14215 and the slider 14216 are mounted on the third fixing member 14212 and are connected in a cooperative manner. When the lead screw 14215 rotates relative to the third fixing member 14212, it can drive the slider 14216 to slide along the length direction of the lead screw 14215. When the third movable member 14213 includes a connecting part 142134, a third fixed member 14212, and a third movable member 14213, the connecting part 142134 is connected to the slider 14216, and the connecting part 142134 moves with the slider 14216, causing the third movable member 14213 to rotate around the first axis under the guidance of the arc track 142122.

[0097] The slider 14216 includes a drive post 142161, the axis of which is parallel to the central axis of the arc-shaped track 142122 and perpendicular to the central axis of the lead screw 14215. The connecting portion 142134 has a receiving hole 142135 for accommodating the drive post 142161. The size of the receiving hole 142135 has a margin; exemplarily, the receiving hole 142135 is an elliptical hole or a strip-shaped hole. The area of ​​the receiving hole 142135 accommodating the drive post 142161 changes with the movement of the third movable member 14213. The drive post 142161 pushes the connecting portion 142134 when the slider 14216 moves, causing the third movable member 14213 to rotate around the first axis without interfering with the stroke of the connecting portion 142134.

[0098] In other embodiments, two of the first rotation unit 1421, the second rotation unit 1422, and the third rotation unit 1423 are angular displacement swing tables, and the other is a rotary table. They are combined and connected to achieve rotational adjustment on three mutually perpendicular rotation axes. For specific settings, please refer to the following.

[0099] In some embodiments, each rotating unit may be configured with a locking mechanism. For example, each rotating unit may lock its corresponding rotating part with a corresponding locking mechanism to fix the rotating units to each other. Alternatively, the rotating units may be locked together by a common locking mechanism. For example, the same locking mechanism may be used to lock the rotating parts of each rotating unit simultaneously to fix the rotating units to each other. Taking the first rotating unit 1421 as an example, the locking mechanism may be a brake pad. A brake pad is provided on the third fixing member 14212. When locking, the brake pad is driven to press against the contact surface of the third moving member 14213 to lock the third moving member 14213 through the friction of the brake pad. The locking mechanism may also be a fixed gear plate. For example, a fixed gear plate is provided on the third fixing member 14212. The fixed gear plate is a gear structure that can mesh with the second arc-shaped rack 142132, but cannot mesh with the second arc-shaped rack 142132 for relative rotation. 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 mesh with the second arc-shaped rack 142132. Since the fixed gear plate cannot mesh with the second arc-shaped rack 142132 and rotate relative to it, the second arc-shaped rack 142132 is locked, and the third movable part 14213 and the third fixed part 14212 are relatively fixed.

[0100] In other embodiments, the rotation module 142 may also employ 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.

[0101] In a second aspect, please refer to FIG1 again. This application embodiment also provides a calibration device 100, including a calibration device 20 and an adjustable bracket 10 as described in the above embodiment. The calibration device 20 is mounted on a fixing component 11.

[0102] Among them, the calibration device 20 can be a target, a calibration pattern, a laser level, etc.
