Initially, ADAS technology was used in luxury cars. As the technology matures and product prices tend to fall, automakers have begun to gradually penetrate into mid-range and small cars. It is estimated that in the future, the number of cars equipped with ADAS technology will be very large, so the automotive aftermarket also needs to launch ADAS calibration services.

[0094] The calibration bracket and the calibration device according to the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0095] Reference Figure 1 , Figure 4 and Fig.18 As shown, the calibration bracket provided in the embodiment of the present invention includes a main frame 10 and a calibration seat 20, wherein there are at least two calibration seats 20, which are arranged on the main frame 10 at intervals in the vertical direction, and each calibration seat 20 has a light receiving surface 201 for receiving a planar laser beam 401 emitted by a laser 40 along the longitudinal direction of the vehicle, wherein a centering mark 202 is provided on the light receiving surface 201, and the centering mark 202 is located in the middle position of the calibration seat 20; the centering marks 202 on at least two calibration seats 20 jointly define a centering plane 2021, the centering plane 2021 is perpendicular to the light receiving surface 201, the light receiving surface 201 intersects with the center line of the main frame 10, the center line of the main frame 10 is on the centering plane 2021, and the center line of the main frame 10 extends along the height direction of the main frame 10.

[0096] Among them, the centering mark 202 can be a centering line or a centering point, and the plane laser beam 401 irradiates the two light-receiving surfaces 201 to form a straight line. It can be understood that the laser straight line formed by the projection of the plane laser beam 401 on the surface of the calibration seat 20 will form a certain angle and position deviation with the centering mark 202 on the calibration seat 20, so that during the calibration process, the position of the main frame 10 can be adjusted to adjust the positions corresponding to the two centering marks 202 on the two calibration seats 20 and the plane laser beam 401, so that the laser straight line formed by the plane laser beam 401 on the two light-receiving surfaces 201 coincides with the two centering marks 202, and then calibrates that the center line of the calibration bracket is aligned with the longitudinal center line of the vehicle; it can be understood that when the plane laser beam 401 is projected on the two light-receiving surfaces 201, the two ends of the formed laser straight line coincide with the two centering marks 202 respectively. When one end does not coincide with the centering mark 202, the calibration bracket can be adjusted to make both ends coincide with the two centering marks 202.

[0097] In some other embodiments, when there are more than two calibration seats 20, when adjusting the center line of the calibration bracket to align with the longitudinal center line of the vehicle, it is only necessary to align the two ends of the planar laser beam 401 with the centering mark 202 to complete the calibration of the calibration bracket, and the calibration operation is simple.

[0098] It can be understood that the light receiving surface 201 can be arranged on the calibration seat 20 at an angle, or it can be arranged on the calibration seat 20 in a vertical direction. The centering plane 2021 is located at the center of the main frame 10 and is perpendicular to the light receiving surface 201. During calibration, when the planar laser beam 401 is parallel to the centering plane 2021, the calibration bracket can be adjusted to make the centering plane 2021 and the planar laser beam 401 coincide with each other, and the two ends of the laser straight line formed by the planar laser beam 401 are aligned with the two centering marks 202, thereby completing the calibration.

[0099] The calibration bracket provided by the present invention aligns and calibrates the center line of the calibration bracket with the longitudinal center line of the vehicle by projecting a plane laser beam 401 emitted along the longitudinal center line of the vehicle onto two calibration seats 20 of the main frame 10, so that the plane laser beam 401 is projected on the light receiving surface 201 in a straight line shape, and then the main frame 10 is adjusted so that the two centering marks 202 on the two light receiving surfaces 201 coincide with the straight plane laser beam 401 projected on the light receiving surface 201, so that the center line of the calibration bracket can be calibrated to be aligned with the longitudinal center line of the vehicle, and the calibration operation is convenient, fast and accurate.

[0100] Refer to the figure Figure 1 and Figure 4 As shown, each light-receiving surface 201 has a plurality of calibration scales 203, and the plurality of calibration scales 203 are arranged in sequence and spaced apart in a direction perpendicular to the centering plane 2021. The centering mark 202 is located in the middle position of the plurality of calibration scales 203. The plurality of calibration scales 203 of at least two calibration seats 20 correspond one to one, and the corresponding calibration scale lines 203 jointly define an offset reference plane 2031, and the offset reference plane 2031 is perpendicular to the light-receiving surface 201.

[0101] In this embodiment, multiple offset reference surfaces 2031 are parallel to each other, and the centering plane 2021 is located in the middle of the multiple offset reference surfaces 2031. When the calibration bracket is not aligned with the plane laser beam 401, the plane laser beam 401 may be located on any one of the multiple offset reference surfaces 2031, or may be located at a position away from the multiple offset reference surfaces 2031, for example, not irradiated on the light-receiving surface 201 of the calibration seat 20. Therefore, when adjusting the calibration bracket and the plane laser beam 401 for alignment, the plane laser beam 401 is projected onto two light-receiving surfaces 201 by moving the calibration bracket. When the plane laser beam 401 is projected onto any two calibration scales 203, the plane laser beam 401 is located on the corresponding offset reference surface 2031. In order to make the center line of the calibration bracket correspond to the plane laser beam 401, the centering mark 202 is aligned with the plane laser beam 401 by continuing to move and adjust the calibration bracket. Thus, it can be calibrated that the center line of the calibration bracket is aligned with the longitudinal center line of the vehicle, thereby completing the calibration.

[0102] Specifically, the main frame 10 includes an adjustment seat 11, a lifting assembly 12, a slide rail 13 and a locking mechanism 14. The adjustment seat 11 is threaded with a plurality of adjustment legs 111, and the adjustment legs 111 are arranged along the height direction of the adjustment seat 11; the lifting assembly 12 is arranged on the adjustment seat 11 along the centerline direction of the main frame 10, and at least two calibration seats 20 are arranged on the lifting assembly 12 at intervals along the vertical direction, and at least one calibration seat 20 is driven to lift by the lifting assembly 12; the slide rail 13 is detachably mounted on the calibration seat 20, and the length direction of the slide rail 13 is perpendicular to the centering plane 2021; the lifting assembly 12 is connected to the adjustment seat 11 by a locking mechanism 14, and the locking mechanism 14 can be switched between a locked position and an unlocked position; when the locking mechanism 14 is in the locked position, the lifting assembly 12 is locked and fixed on the adjustment seat 11; when the locking mechanism 14 is in the unlocked position, the locking mechanism 14 releases the lock on the lifting assembly 12.

[0103] In this embodiment, when fine-tuning and aligning the calibration bracket with the planar laser beam 401, the main frame 10 uses the adjustment foot 111 to adjust the pitch angle and the roll angle. The adjustment foot 111 passes through the adjustment seat 11 and can be against the ground. During the calibration process, the adjustment foot 111 can stably place the calibration bracket on the ground, and then adjust the adjustment foot 111 according to the position of the planar laser beam 401 on the two light-receiving surfaces 201, so that the adjustment foot 111 drives the main frame 10 to complete the angle adjustment of the pitch angle and the roll angle, so that the two ends of the planar laser beam 401 are aligned with the two centering marks 202; it can be understood that the angle can be fine-tuned when adjusting the adjustment foot 111, thereby making the alignment of the calibration bracket and the longitudinal center line of the vehicle more accurate and the calibration more accurate.

[0104] Among them, after the center line of the calibration bracket is aligned with the longitudinal center line of the vehicle, the length direction of the slide rail 13 is perpendicular to the centering plane 2021 to ensure that the light-receiving surface 201 is perpendicular to the longitudinal center line of the vehicle, and then the front bumper or front wheel center line of the vehicle can be used as the distance measurement reference to calibrate the parallelism between the slide rail 13 and the measurement reference to accurately measure the placement distance between the calibration bracket and the measurement reference.

[0105] It can be understood that the calibration seat 20 is arranged on the lifting assembly 12, and the slide rail 13 is arranged on the calibration seat 20, so that the height of the slide rail 13 can be adjusted by the lifting assembly 12, and then the slide rail 13 is adjusted to a suitable height for calibration; it can be understood that the detachable arrangement between the lifting assembly 12 and the adjustment seat 11 can make it possible to disassemble the lifting assembly 12 and the adjustment seat 11 after the calibration is completed, and the storage is more convenient; and the adjustment seat 11 can be made of cast iron, wherein cast iron is a general term for alloys mainly composed of iron, carbon and silicon. The adjustment seat 11 made of cast iron is heavier as a whole, has better stability, and is more conducive to calibration operations.

[0106] Reference Figure 5 and Fig.11 As shown, the lifting assembly 12 includes a hollow seat 121, a slide rod 122, a lifting seat 123 and a driving assembly 124. The hollow seat 121 is fixed on the adjustment seat 11; the slide rod 122 is fixed in the hollow seat 121; the lifting seat 123 is arranged in the hollow seat 121 and is sleeved on the slide rod 122 and can be lifted and lowered; the driving assembly 124 is fixed on the hollow seat 121 and is transmission-connected with the lifting seat 123, and is used to drive the lifting seat 123 to move relative to the hollow seat 121.

[0107] Among them, a bottom plate 126 is fixed to the bottom of the slide bar 122, and the hollow seat 121 is fixed to the bottom plate 126 and contains the slide bar 122. The bottom plate 126 is fixed to the adjusting seat 11 through the locking mechanism 14, so that the slide bar 122 and the adjusting seat 11 are fixed to each other, and then the lifting seat 123, the slide bar 122 and the driving assembly 124 are fixed on the adjusting seat 11 together, and the slide bar 122 can be provided with two linear bearings 1231 fixed at the position of the lifting seat 123 corresponding to the slide bar 122, the linear bearing 1231 is movably sleeved on the slide bar 122, and the lifting seat 123 can be driven to rise and fall in the vertical direction through the driving assembly 124, and the slide rail 13 is installed on the lifting seat 123, so that the lifting seat 123 drives the slide rail 13 to rise and fall to adjust the height of the slide rail 13.

[0108] In addition, a rack 125 is provided on the lifting seat 123, and the rack 125 is parallel to the sliding rod 122 along the length direction. The driving assembly 124 includes a worm 1241, a worm wheel 1242, a gear 1243 and a handwheel 1244. The worm 1241 is rotatably mounted on the hollow seat 121 and is vertically spaced from the rack 125; the worm wheel 1242 is meshed with the worm 1241 for transmission, and the worm wheel 1242 is fixedly connected to a worm wheel shaft (not shown in the figure), one end of the worm wheel shaft is rotatably mounted on the hollow seat 121 and is vertically arranged with the worm 1241, and the other end of the worm wheel shaft extends to one side of the rack 125; the gear 1243 is arranged on the worm wheel shaft and meshes with the rack 125 to drive the rack 125 to move when the worm wheel 1242 rotates; the handwheel 1244 is arranged at one end of the worm 1241 to drive the worm 1241 to rotate.

[0109] In this embodiment, when the lifting seat 123 is raised or lowered, the hand wheel 1244 is rotated to drive the worm 1241 and the worm wheel 1242 for transmission, and the gear 1243 drives the rack 125 to drive the lifting seat 123 to be raised or lowered relative to the hollow seat 121. In some other embodiments, the worm 1241 and the worm wheel 1242 can also be driven by a motor or the like to transmit the transmission, which can make the adjustment method more diversified and simpler and more convenient.

[0110] Reference Figure 4 As shown, the calibration seat 20 includes a connecting portion 204 and a supporting portion 205, the rear end of the connecting portion 204 is connected to the lifting assembly 12; the supporting portion 205 is connected to the connecting portion 204 and extends toward the front end of the connecting portion 204, and the slide rail 13 is detachably mounted on the supporting portion 205. When installing the calibration seat 20, the calibration seat 20 can be fixed to the lifting bracket by passing bolts through the connecting portion 204, and then when installing the slide rail 13, the slide rail 13 can be directly placed on the supporting portion 205, so that the supporting portion 205 supports the slide rail 13, and then the slide rail 13 is fixed, which makes the installation simpler.

[0111] Furthermore, the supporting portion 205 has an installation groove 2051 extending from left to right, and at least two positioning blocks 206 are protruding from the installation groove 2051. The bottom of the slide rail 13 has a positioning groove 134 adapted to the positioning block 206. When the slide rail 13 is installed on the supporting portion 205, the positioning block 206 is embedded in the positioning groove 134.

[0112] It can be understood that when the slide rail 13 is placed on the supporting portion 205, the positioning block 206 and the positioning groove 134 embedded in the bottom of the slide rail 13 are used so that the positioning block 206 can limit and fix the slide rail 13, and the bottom of the slide rail 13 can be fitted with the supporting portion 205, thereby, the slide rail 13 is installed more stably on the supporting portion 205; optionally, the positioning block 206 can be detachably connected to the supporting portion 205, for example, the positioning block 206 can be fixed in the installation groove 2051 by bolts, and the width of the positioning groove 134 is consistent with the width of the positioning block 206, and the positioning block 206 can be set to gradually reduce the width from bottom to top, so that the positioning block 206 can be embedded in the positioning groove 134 faster and more accurately, making the installation and fixation of the slide rail 13 more convenient.

[0113] Specifically, a positioning column 207 extending vertically upward is provided in the installation groove 2051, and the positioning column 207 is arranged between at least two positioning blocks 206. A positioning hole 1313 adapted to the positioning column 207 is provided in the slide rail 13. When the slide rail 13 is installed on the supporting portion 205, the positioning column 207 is inserted into the positioning hole 1313.

[0114] In this embodiment, the height of the positioning column 207 is higher than the height of the positioning block 206. Therefore, in order to make the installation of the slide rail 13 more accurate and stable, the positioning column 207 is combined with the two positioning blocks 206. When installing the slide rail 13, the positioning column 207 can be accurately inserted into the positioning hole 1313. When the slide rail 13 continues to be lowered, the two positioning blocks 206 can be accurately embedded in the positioning groove 134, thereby completing the installation of the slide rail 13, and the installation is simple and convenient. It can be understood that when the slide rail 13 is installed on the supporting portion 205, the slide rail 13 will be restricted in the horizontal direction by the two positioning blocks 206, so that the slide rail 13 cannot rotate, thereby ensuring that the position of the slide rail 13 is more accurate and not easy to offset.

[0115] In some other embodiments, the positioning block 206 and the positioning column 207 can also be installed at the bottom of the slide rail 13, and a positioning groove 134 and a positioning sleeve 131 are set on the supporting portion 205, thereby, the slide rail 13 can also be quickly installed. That is to say, the positions of the positioning column 207 and the positioning block 206 can be set according to actual needs to make the installation of the slide rail 13 simpler and more stable.

[0116] Reference Figures 2 to 4 As shown, a positioning sleeve 131 is embedded in the slide rail 13, and the positioning sleeve 131 has a fixed end 1311 and a sleeve end 1312 connected to each other. The fixed end 1311 is connected and fixed to the slide rail 13 by a locking bolt, and the sleeve end 1312 is located below the fixed end 1311. A positioning hole 1313 is formed in the sleeve end 1312 and is plugged into the positioning column 207.

[0117] In this embodiment, when the positioning sleeve 131 is fixed on the slide rail 13, it can be locked and fixed by using a locking bolt and a fixed end 1311 of the positioning sleeve 131, so that the positioning sleeve 131 can be fixed in the slide rail 13, and the whole is tighter and more reliable. Therefore, when installing the slide rail 13, the slide rail 13 can be directly sleeved on the positioning column 207 through the sleeve end 1312 of the positioning sleeve 131, so that the positioning column 207 is in the positioning hole 1313, thereby positioning and installing the slide rail 13, and the installation is simple and convenient.

[0118] Specifically, a clamping assembly 21 is provided on the top of the connecting portion 204, and the clamping assembly 21 can pivot between a clamping position and a releasing position. When the clamping assembly 21 pivots to the clamping position, the slide rail 13 is fixed to the supporting portion 205 by the clamping assembly 21; when the clamping assembly 21 pivots to the releasing position, the clamping assembly 21 releases the fixing of the slide rail 13 so that the slide rail 13 can be removed from the supporting portion 205.

[0119] Among them, when the clamping component 21 pivots to the clamping position, the clamping component 21 can be pressed against the top of the slide rail 13, so that the slide rail 13 is pressed against the supporting portion 205, and the slide rail 13 is restricted from moving in the vertical direction. Through the combination of the clamping component 21 and the positioning block 206, the slide rail 13 is restricted from moving in both the horizontal and vertical directions, so that the slide rail 13 is fixed more stably and the installation is quick and convenient.

[0120] Specifically, the fastening assembly 21 includes a fastener 212 and a fastening member 211. The fastener 212 passes through the fastening member 211 and is threadedly connected to the connecting portion 204. The fastening member 211 is rotatable around the axis of the fastener 212. When the fastener 212 is tightened, the fastening member 211 is pressed and fixed by the fastener 212.

[0121] In this embodiment, when the fastening member 211 secures the slide rail 13, the fastening member 211 can be tightened and fixed by the fastener 212, so that the fastening member 211 cannot rotate, thereby preventing the fastening member 211 from rotating during use, thereby fixing the slide rail 13 and improving stability; it can be understood that in some other embodiments, an elastic buckle can also be provided on the fastening member 211, and when the fastening member 211 is rotated to the top of the slide rail 13, it can be buckled with the slide rail 13 by the elastic buckle, thereby preventing the fastening member 211 from rotating and the slide rail 13 is fixed more stably, and the installation is simpler and more convenient.

[0122] Furthermore, the clamping member 211 has a pivot portion 2111 and a clamping portion 2112, the pivot portion 2111 is pivotally connected to the connecting portion 204 around its own axis, and the axis of the pivot portion 2111 extends vertically; the clamping portion 2112 is connected to the pivot portion 2111 and extends horizontally, and can pivot with the pivot portion 2111 between a clamping position and a release position.

[0123] Among them, when the slide rail 13 is installed on the calibration seat 20, the top of the slide rail 13 and the bottom surface of the clamping portion 2112 are at the same horizontal position. By rotating the clamping portion 2112, the clamping portion 2112 is rotated to the top of the slide rail 13 relative to the pivot portion 2111, so that the clamping portion 2112 is abutted against the top of the slide rail 13, and then the slide rail 13 is clamped and fixed, so that the slide rail 13 is restricted from moving in the vertical direction, and the installation of the slide rail 13 on the calibration seat 20 is more stable; that is, when installing the slide rail 13, you only need to place the slide rail 13 horizontally on the calibration seat 20, and then fix it with the clamping assembly 21 to complete the installation of the slide rail 13. The installation steps are simple and the efficiency of calibration can be improved.

[0124] It is understandable that in some other embodiments, the slide rail 13 and the calibration seat 20 may be fixed by means of threaded connection or snap connection, so that the slide rail 13 can be fixed on the calibration seat 20 more stably.

[0125] Furthermore, the pivotal portion 2111 is provided with a through hole 2113 extending vertically, and the connecting portion 204 is provided with a threaded hole 2041. The fastener 212 passes through the through hole 2113 and is threadedly connected to the threaded hole 2041 to fix the pivotal portion 2111 on the connecting portion 204; wherein, the fastener 212 can be a bolt, and the fastener 212 passes through the through hole 2113 and is threadedly connected to the threaded hole 2041, thereby allowing the fastener 212 to bolt the fastening member 211, and then allowing the fastening member 211 to tighten the slide rail 13, thereby providing better stability and more convenient installation.

[0126] Specifically, the calibration seat 20 further includes a limit piece 208 disposed on both sides of the connection portion 204, and the limit piece 208 extends to both sides of the lifting assembly 12 to limit the horizontal movement of the calibration seat 20. The limit piece 208 extends from the calibration seat 20 to the lifting bracket, so that the calibration seat 20 can be clamped by the limit piece 208. Through the combination of the limit piece 208 and the positioning block 206, the calibration seat 20 can be limited in the horizontal direction to be more stable, and the calibration seat 20 and the slide rail 13 can be prevented from positionally offset during the calibration process.

[0127] Reference Figures 8 to 10As shown, the locking mechanism 14 includes a sleeve 141, a locking member 142 and an elastic member 143, the sleeve 141 is fixed on the lifting assembly 12; the locking member 142 is inserted into the sleeve 141; the elastic member 143 is sleeved on the locking member 142 and is located in the sleeve 141, the first end of the elastic member 143 abuts against the locking member 142, and the second end of the elastic member 143 abuts against the lifting assembly 12; wherein the locking member 142 is configured to be pressed downward along its axial direction for a predetermined distance and then rotated by a predetermined angle, so that the lifting assembly 12 and the adjustment seat 11 can be locked and fixed.

[0128] In this embodiment, when the locking member 142 is pressed by the user, the elastic member 143 can be compressed to move axially toward the adjustment seat 11, so that the locking member 142 is in an unlocked position, and the locking member 142 can be rotated in the unlocked position; when the locking member 142 is released, the elastic force of the elastic member 143 can push the locking member 142 to move axially in the direction away from the adjustment seat 11, so that the locking member 142 is elastically fixed by the elastic member 143, and the locking member 142 cannot rotate.

[0129] Furthermore, the locking member 142 includes a shaft portion 1421, an operating portion 1422, a limiting portion 1423 and a stopper portion 1424. The shaft portion 1421 is inserted into the sleeve 141, and the upper end of the shaft portion 1421 extends from the top of the sleeve 141, and the lower end of the shaft portion 1421 passes through the bottom of the lifting assembly 12 and passes through the adjustment seat 11; the operating portion 1422 is arranged at the upper end of the shaft portion 1421 and extends along the radial direction of the shaft portion 1421, and is used for the user to operate and drive the shaft portion 1421 to move; the limiting portion 1423 is arranged at the shaft portion 1421. The lower end of 421 extends along the radial direction of the shaft portion 1421 to move together with the shaft portion 1421; when the operating portion 1422 is pressed downward along the axial direction of the shaft portion 1421 for a predetermined distance and then rotated by a predetermined angle, the limiting portion 1423 stops below the bottom of the adjustment seat 11 to lock and fix the lifting assembly 12 to the adjustment seat 11; optionally, a stop portion 1424 is protruded in the radial direction on the circumferential surface of the shaft portion 1421 and is located in the sleeve 141, and the first end of the elastic member 143 abuts against the stop portion 1424.

[0130] That is to say, when the locking member 142 is pressed, the stop portion 1424 moves with the shaft portion 1421 and pushes the compression elastic member 143, so that the shaft portion 1421 can rotate. During specific operation, the operation portion 1422 can be used to press and rotate; when the locking member 142 is released, the elastic member 143 can push the stop portion 1424 to elastically move and cause the shaft portion 1421 to be bounced up, and the limiting portion 1423 is bounced up along with the shaft portion 1421, so that the limiting portion 1423 is elastically stopped at the bottom of the adjustment seat 11.

[0131] Reference Fig. 9As shown, the adjustment seat 11 has a through hole 112 corresponding to the limiting portion 1423. When the operating portion 1422 is pressed downward along the axial direction of the shaft 1421 for a predetermined distance and then rotated by a predetermined angle, the limiting portion 1423 passes through the through hole 112 and stops below the bottom of the adjustment seat 11.

[0132] In this embodiment, when installing the lifting assembly 12, the lifting assembly 12 is arranged on the adjusting seat 11, and the limiting portion 1423 is aligned with the through hole 112 on the adjusting seat 11, so that the lifting assembly 12 is placed flat on the adjusting seat 11, and then the operating portion 1422 is pressed down and the elastic member 143 is compressed to make the limiting portion 1423 pass through the through hole 112 and enter under the adjusting seat 11, and then the operating portion 1422 is rotated to make the limiting portion 1423 rotate a predetermined angle, and then be elastically stopped by the elastic member 143 to abut against the bottom of the adjusting seat 11.

[0133] Furthermore, a limiting groove 113 is provided at the bottom of the adjustment seat 11, and the limiting portion 1423 can rotate in the limiting groove 113. The bottom of the limiting groove 113 has a first limiting surface 1131 and a second limiting surface 1132. The through hole 112 is provided in the limiting groove 113 and is located between the first limiting surface 1131 and the second limiting surface 1132; when the operating portion 1422 is pressed downward along the axial direction of the shaft portion 1421 for a predetermined distance and then rotated by a predetermined angle, the limiting portion 1423 passes through the through hole 112 to stop on the first limiting surface 1131 and the second limiting surface 1132.

[0134] Among them, the first limiting surface 1131 and the second limiting surface 1132 form a 90-degree angle with each other. When the limiting portion 1423 is pressed through the through hole 112 and enters the bottom of the adjustment seat 11, the limiting portion 1423 is rotated by a predetermined angle to enter the limiting groove 113, and the operating portion 1422 is released, so that the elastic member 143 pushes the stopper 1424 and drives the shaft 1421 and the limiting portion 1423 to bounce up together, so that the limiting portion 1423 stops on the first limiting surface 1131 and the second limiting surface 1132, thereby completing the fixation of the lifting assembly 12 and the adjustment seat 11; it can be understood that the predetermined angle can be greater than 0 degrees and less than or equal to 90 degrees; therefore, the elastic member 143 can The limiting portion 1423 is always kept in the locked position. When the lifting assembly 12 is disassembled, the operating portion 1422 is rotated to drive the shaft 1421 and the limiting portion 1423 to rotate. When the limiting portion 1423 is rotated to correspond to the through hole 112, the elastic force of the elastic member 143 pushes the limiting portion 1423 to bounce up into the through hole 112, so that the limiting portion 1423 is disengaged from the limiting groove 113, and then the lifting assembly 12 and the adjusting seat 11 are disassembled, thereby completing the removal of the lifting assembly 12 and the adjusting seat 11. Therefore, the lifting assembly 12 and the adjusting seat 11 can be installed and disassembled by simply operating the locking member 142, and the installation and disassembly are faster and more convenient, which is more conducive to simplifying the calibration steps.

[0135] Reference Figures 12 to 15 As shown, an anti-slip mechanism 30 is provided on the slide rail 13, and the anti-slip mechanism 30 includes a sliding plate 31 and a hanging plate 32 for hanging a radar calibration component 34. The sliding plate 31 can be slidably installed on the slide rail 13, and the hanging plate 32 is fixed on the sliding plate 31; a limiting component 33 is provided on the sliding plate 31, and an operating member 331 is provided on the limiting component 33, and the operating member 331 can pivot between a locking position and an unlocking position; when the operating member 331 is in the locking position, the sliding plate 31 is locked and fixed on the slide rail 13; when the operating member 331 is in the unlocking position, the sliding plate 31 can slide on the slide rail 13.

[0136] In this embodiment, the radar calibration component 34 is used to align and correct the measurement position on the automobile. Therefore, when calibrating the radar calibration component 34, it can be placed on a calibration bracket for calibration. When installing, the radar calibration component 34 can be hung on the hanging plate 32, and then the position of the radar calibration component 34 can be adjusted by the sliding plate 31, and the movement of the sliding plate 31 can be limited by the limit assembly 33, thereby limiting the position of the radar calibration component 34.

[0137] Among them, the operating member 331 is pivoted to the unlocking position so that the sliding plate 31 is unlocked, and then the sliding plate 31 is pushed to move on the slide rail 13, and the operating member 331 is pivoted to the locking position so that the sliding plate 31 can be locked and fixed on the slide rail 13, and then the radar calibration component 34 is hung on the hanging plate 32, so that the position of the radar calibration component 34 is limited and fixed, the limiting operation is more convenient, the operation is simple and the stability is better during the calibration process.

[0138] Reference Fig.15 and Fig.17 As shown, the limiting assembly 33 also includes a fixing sleeve 332 and a locking shaft 333. The fixing sleeve 332 is fixed on the sliding plate 31. One end of the locking shaft 333 is embedded in the slide groove 132 of the slide rail 13 and can slide. The other end of the locking shaft 333 passes through the slide plate 31 and the fixing sleeve 332 and extends out of the fixing sleeve 332. The operating member 331 is pivotally connected to the other end of the locking shaft 333. The fixing sleeve 332 is fixed to the slide plate 31 by screws and can slide on the slide rail 13 together with the slide plate 31. The locking shaft 333 can also move with the slide plate 31. Then, the position of the slide plate 31 can be limited by the limiting assembly 33 at any position of the slide rail 13, and the adjustment is more convenient and simple.

[0139] Furthermore, a stop wall 133 is provided on one side of the slide slot 132 close to the slide plate 31 , and the locking shaft 333 has a stop portion 3331 protruding along its radial direction. The stop portion 3331 is located in the slide slot 132 and can be stopped on the stop wall 133 .

[0140] In this embodiment, the sliding plate 31 and the stopping wall 133 are clamped by the fixing sleeve 332 and the stopping portion 3331. When the locking shaft 333 moves toward the direction close to the stopping wall 133, the fixing sleeve 332 will move relative to the locking shaft 333 toward the direction away from the stopping wall 133, thereby unlocking the sliding plate 31. When the fixing sleeve 332 moves toward the stopping wall 133 and the locking shaft 333 drives the stopping portion 3331 to move away from the stopping wall 133, the stopping portion 3331 and the fixing sleeve 332 approach each other, thereby squeezing and clamping the sliding plate 31 and the stopping wall 133 to fix the sliding plate 31, and the clamping is more stable and the limiting is more accurate and reliable.

[0141] Specifically, the operating member 331 includes an operating end 3311 and a pivot end 3312 connected to each other. The operating end 3311 is used for user operation. The pivot end 3312 has an eccentric hole 3314. The eccentric hole 3314 is pivotally connected to the other end of the locking shaft 333 through a pivot pin. When the operating end 3311 is operated to force the operating member 331 to rotate a predetermined angle, the operating member 331 is in a locked position.

[0142] In this embodiment, the predetermined angle can be 90 degrees, etc. When the operating member 331 is rotated to the predetermined angle, the operating member 331 pushes the fixing sleeve 332 to move toward the stopping wall 133, and at the same time pulls the locking shaft 333 to drive the stopping portion 3331 to move toward the stopping wall 133, thereby making the sliding plate 31 and the slide rail 13 close to each other to lock the sliding plate 31 on the slide rail 13; it can be understood that when the operating member 331 is rotated in the opposite direction by a predetermined angle, the fixing sleeve 332 moves in a direction away from the stopping wall 133, and at the same time the stopping portion 3331 moves in a direction away from the stopping wall 133, so that the sliding plate 31 and the slide rail 13 move away from each other to unlock the sliding plate 31, thereby making the operation more convenient and simple, and having better stability.

[0143] Furthermore, if Fig.16 and Fig.17 As shown, a groove 3321 is provided on the fixing sleeve 332, and the pivot end 3312 abuts against the groove 3321. The pivot end 3312 has a convex portion 3313 away from the eccentric hole 3314. When the operating member 331 rotates a predetermined angle (90 degrees), the convex portion 3313 rotates into the groove 3321, squeezing and pushing the fixing sleeve 332, and the locking shaft 333 moves relative to the fixing sleeve 332, so that the fixing sleeve 332 presses and fixes the sliding plate 31 on the slide rail 13.

[0144] In this embodiment, when the sliding plate 31 is slidable, the operating member 331 can be rotated by a predetermined angle so that the protrusion 3313 is rotated into the groove 3321, and the fixing sleeve 332 is squeezed and pushed so that the fixing sleeve 332 and the stopping portion 3331 are close to each other, thereby causing the fixing sleeve 332 to press the sliding plate 31 onto the slide rail 13, so that the sliding plate 31 remains in a compressed state; when the sliding plate 31 is compressed and locked, the operating member 331 is rotated in the opposite direction by a predetermined angle so that the protrusion 3313 is rotated away from the groove 3321, so that the fixing sleeve 332 is released from the compressed and pushed state and moves in a direction away from the stopping wall 133, thereby releasing the sliding plate 31 from the compressed state, allowing the sliding plate 31 to slide, and then the position of the sliding plate 31 and the hanging plate 32 can be adjusted.

[0145] Furthermore, the plane direction of the mounting plate 32 is parallel to the plane direction of the sliding plate 31 and they define a mounting space 322 together. The mounting plate 32 is provided with a mounting groove 321. The radar calibration component 34 is provided with a mounting component 341. The mounting component 341 is suitable for mounting in the mounting groove 321, so that the mounting plate 32 stops a part of the mounting component 341 in the mounting space 322. When installing the radar calibration component 34, the mounting component 341 of the radar calibration component 34 can be directly mounted on the mounting plate 32, so that the sliding plate 31 and the mounting plate 32 can clamp the mounting component 341, and then the radar calibration component 34 is fixed on the mounting plate 32, and the installation is simpler and more convenient.

[0146] Reference Figure 1 , Figure 5 and Fig.18 As shown, an angle scale mark 101 for receiving a plane laser beam 401 emitted by a laser along the longitudinal direction of the vehicle is attached to the lower end of the main frame 10, the plane where the angle scale mark 101 is located is perpendicular to the centering plane 2021, and the 90-degree scale line on the angle scale mark 101 is on the centering plane 2021. When the plane laser beam 401 is projected onto the light-receiving surface 201, the degree of deviation between the laser line and the centering mark 202 can be easily known by observing the correspondence between the laser line formed by the plane laser beam 401 on the angle scale mark 101 and the angle scale mark 101. That is, when the plane laser beam 401 is irradiated onto the light-receiving surface 201 and coincides with the centering mark 202, the plane laser beam 401 indicates the position of the 90-degree scale line, thereby completing the calibration of the calibration bracket and the longitudinal center line of the vehicle.

[0147] Reference Fig.18 As shown, the present invention also provides a calibration device, including a laser 40 and a calibration bracket as described above, wherein the laser 40 is used to emit a planar laser beam 401 along the longitudinal center line of the vehicle; the planar laser beam 401 emitted by the laser 40 is projected onto at least two light receiving surfaces 201 to form a straight laser line.
