Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise specifically limited.

[0047] Please refer to Figure 1 and Figure 2 , the mounting bracket 1 provided by the embodiments of the present application will be described. The mounting bracket 1 is applied to a calibration device, and the beam assembly 100 is used to fix a calibration element for calibrating or calibrating a vehicle sensor, for example, to fix a radar calibration device, or to fix a target for calibration or calibration.

[0048] The mounting bracket 1 comprises a beam assembly 100, two cameras 700, a plurality of mounting devices 600 and a support assembly 800; the two cameras 700 are respectively mounted at opposite ends of the beam assembly 100; the plurality of mounting devices 600 at least comprises two first mounting devices 600a and a second mounting device 600b; the two first mounting devices 600a are respectively slidably arranged on the beam assembly 100, and the two first mounting devices 600a are used to jointly clamp a first calibration element; the support assembly 800 is arranged below the beam assembly 100 and is used to support the first calibration element; the second mounting device 600b is slidably arranged between the two first mounting devices 600a, and the second mounting device 600b is used to mount a second calibration element.

[0049] The two cameras 700 are used to acquire wheel images on both sides of the vehicle or acquire target images arranged on the wheels, so as to realize calibration and calibration of the wheels on both sides of the vehicle.

[0050] The two first mounting devices 600a are arranged on the beam assembly 100 in a spaced manner, and the two first mounting devices 600a are both capable of sliding on the beam assembly 100. When the first calibration element is mounted, the two first mounting devices 600a can be adjusted according to the transverse size of the first calibration element, and then the opposite sides of the first calibration element are respectively inserted into the two insertion slots 612 of the two first mounting devices 600a to clamp the first calibration element by the two first mounting devices 600a. In addition, when the size or weight of the first calibration element is large, the bottom of the first calibration element can be supported on the support assembly 800 to assist the mounting of the first calibration element.

[0051] It should be noted that the two first mounting devices 600a are used in cooperation to mount the first calibration element with a large size, and the second mounting device 600b can independently realize the second calibration element with a relatively small size. In the actual calibration process, the mounting scheme can be selected according to the actual size of the calibration element.

[0052] The mounting bracket 1 in the embodiment of the application is provided with the two cameras 700, the two first mounting devices 600a, the second mounting device 600b and the support assembly 800 on the beam assembly 100, so that the mounting bracket 1 can realize calibration and calibration of the wheels on both sides of the vehicle by the two cameras 700, and the two first mounting devices 600a can be used in cooperation to clamp the first calibration element with a relatively large size, the calibration position is adjustable, and the support assembly 800 can be used for auxiliary support when the weight of the first calibration element is large. In addition, the second calibration element with a relatively small size can be mounted by the second mounting device 600b, and the calibration position is adjustable. In summary, the mounting bracket 1 of the application can realize mounting of calibration elements with different sizes, and can also adjust the horizontal position of the calibration element, so as to meet the calibration requirements of different sensors of the vehicle, reduce the number of calibration equipment, and reduce the calibration operation of the vehicle.

[0053] In some embodiments, please refer to Figure 3The support assembly 800 comprises two swing arms 810 and two support wheels 820. The two swing arms 810 are respectively arranged at the bottom side of the cross beam assembly 100 and can rotate in a vertical plane. The two support wheels 820 are respectively arranged at the hanging ends of the two swing arms 810 and extend from the bottom side of the cross beam assembly 100 to the front side. The outer circumferential surface of the support wheel 820 is concavely provided with an annular groove 821. The rotation of the two swing arms 810 can drive the two support wheels 820 to stay at different height positions to support the first calibration element at different height positions. In addition, the support wheel 820 is arranged such that the annular groove 821 on the support wheel 820 can achieve clamping support of the first calibration element regardless of the rotation angle of the swing arm 810.

[0054] In some embodiments, referring to Figure 3 , the two swing arms 810 are staggered along the front-rear direction of the cross beam assembly 100. When the two swing arms 810 are folded at the bottom side of the cross beam assembly 100, the two swing arms 810 cross along the length extension direction of the cross beam assembly 100.

[0055] It should be noted that the front-rear direction of the cross beam assembly 100 refers to the direction perpendicular to the vertical direction of the cross beam assembly 100 and the length extension direction of the cross beam assembly 100, for example, the distribution direction of the cross beam assembly 100 and the target. Specifically, the front-rear direction of the cross beam assembly 100 is as indicated by the arrow in Figure 3 .

[0056] In this embodiment, the two swing arms 810 are staggered along the front direction of the cross beam assembly 100, so that when the two swing arms 810 are rotated to be folded at the bottom side of the cross beam assembly 100, the two swing arms 810 can at least partially cross and repeat along the length extension direction of the cross beam assembly 100, so that the length of the two swing arms 810 can be set longer to meet the support of first calibration elements of different sizes. It can be understood that in other embodiments of the present application, when the length of the swing arm 810 does not need to be very long, the two swing arms 810 can not be arranged staggered along the front direction, and the two swing arms 810 can not be arranged cross along the length extension direction.

[0057] In some embodiments, referring to Figure 4 and Figure 5The bottom side of the crossbeam assembly 100 is provided with a first mounting member 830 and two wave screws 840 mounted on the first mounting member 830 and arranged oppositely. The swing arm 810 is provided with a limiting protrusion 852 which can be clamped between the two wave screws 840. The wave screws 840 are elastic, and the limiting protrusion 852 is clamped between the two wave screws 840 by the elasticity of the wave screws 840, so as to limit the swing arm 810 in the folded state. In operation, the swing arm 810 only needs to be manually rotated until it is folded on the bottom side of the crossbeam assembly 100, and the limiting protrusion 852 on the swing arm 810 can be clamped between the two wave screws 840 by pressing the swing arm 810.

[0058] In one embodiment, referring to Figure 5 The first mounting member 830 is locked on the crossbeam assembly 100 by screws. The first mounting member 830 includes a first bottom plate 831 and mounting barrels 832 formed on the first bottom plate 831 and arranged at intervals. The two wave screws 840 are mounted on the two mounting barrels 832 and at least partially extend into the gap between the two mounting barrels 832.

[0059] In some embodiments, referring to Figure 5 The swing arm 810 is provided with a second mounting member 850. The second mounting member 850 includes a second bottom plate 851 and a limiting protrusion 852 formed on the second bottom plate 851. The connecting part of the limiting protrusion 852 and the second bottom plate 851 is concave and forms an arc-shaped slot 853. When the limiting protrusion 852 is inserted between the two wave screws 840, the two wave screws 840 are clamped in the arc-shaped slot 853 to increase the clamping force.

[0060] In some embodiments, referring to Figure 3 and Figure 4 The crossbeam assembly 100 is provided with a third hinge seat 860, and the hinge end of the swing arm 810 is hinged to the third hinge seat 860 through a rotating shaft. A friction sheet 870 is arranged between the swing arm 810 and the third hinge seat 860. The rotating damping of the swing arm 810 is increased by the friction sheet 870, so that the swing arm 810 can stay at any position to support the first calibration element. It can be understood that in other embodiments of the present application, a locking structure can also be arranged to lock the swing arm 810 at any position, which is not limited herein.

[0061] In some embodiments, the crossbeam assembly 100 is provided with a first detector for detecting whether the two ends of the crossbeam assembly 100 are flush. Through the arrangement of the first detector, the two cameras 700 at the two ends can be ensured to be flush, so as to ensure the calibration accuracy of the cameras 700 at the two sides.

[0062] In one specific embodiment, referring to Figure 2 and Figure 4The first detector includes two gyroscopes 900, which are symmetrically arranged relative to the length center of the beam assembly 100. The two symmetrically arranged gyroscopes 900 detect the azimuth, level and position of the left and right parts of the beam assembly 100 respectively, so as to feedback whether the two sides of the camera 700 are aligned, so that the user can adjust the levelness of the beam assembly 100. It can be understood that in other embodiments of the present application, the above-mentioned first detector can also be other detection devices, such as a level, a total station or a laser level.

[0063] In some embodiments, referring to Figure 2 、 Figures 6 to 8 The beam assembly 100 includes a first beam unit 110 and two second beam units 120, and the two second beam units 120 are respectively connected to opposite ends of the first beam unit 110. The mounting bracket 1 further includes a hinged assembly 200, a first locking assembly 300 and a second locking assembly 400. The hinged assembly 200 is connected between the first beam unit 110 and the second beam unit 120, so that the second beam unit 120 has an unfolded state of being parallel to the first beam unit 110 and a folded state of being perpendicular to the first beam unit 110. The first locking assembly 300 is used to lock the second beam unit 120 in the folded state, and the second locking assembly 400 is used to lock the second beam unit 120 in the unfolded state.

[0064] When mounting, the first beam unit 110 is mounted on the column 2 of the calibration device. When using, the two second beam units 120 are unfolded relative to the first beam unit 110 to the unfolded state, and the two second beam units 120 are locked in the unfolded state by the second locking assembly 400. At this time, the calibration element can be mounted on the first beam unit 110 and / or the second beam unit 120, so as to realize the calibration and calibration of the sensor on the automobile. When storing or carrying, the two second beam units 120 are vertically folded relative to the first beam unit 110 to the folded state, specifically folded to opposite sides of the column 2 and arranged in parallel with the column 2, and the two second beam units 120 are locked in the folded state by the first locking assembly 300, so as to facilitate storage and carrying.

[0065] In the embodiment, the two second beam units 120 can be parallelly unfolded or vertically folded relative to the first beam unit 110 through the arrangement of the hinged assembly 200. The parallel unfolding can make the size of the mounting bracket 1 larger, so as to mount different calibration elements. The vertical folding can make the second beam units 120 on both sides of the first beam unit 110 fold relative to the first beam unit 110, so as to reduce the occupied space of the mounting bracket 1 and facilitate storage and transportation. In addition, the first locking assembly 300 and the second locking assembly 400 can lock the second beam units 120 in the folded state and the unfolded state, so as to ensure the unfolding stability and the folding stability of the mounting bracket 1.

[0066] In some embodiments, referring to Figures 7 to 8 , the hinged assembly 200 includes a first hinged unit 210 and a second hinged unit 220 hinged to each other. The first hinged unit 210 and the second hinged unit 220 are respectively installed on the first beam unit 110 and the second beam unit 120. The first hinged unit 210 has a first abutting surface 213, and the second hinged unit 220 has a second abutting surface 2211. When the second beam unit 120 is in the unfolded state, the second abutting surface 2211 is perpendicular to the first abutting surface 213. When the second beam unit 120 is in the folded state, the second abutting surface 2211 abuts against the first abutting surface 213.

[0067] The first hinged unit 210 and the second hinged unit 220 are hinged to each other to rotate the second beam unit 120 relative to the first beam unit 110 to the unfolded state and to rotate the second beam unit 120 relative to the first beam unit 110 to the folded state. Meanwhile, the first abutting surface 213 and the second abutting surface 2211 can limit the rotation angle of the second beam unit 120 to avoid the second beam unit 120 continuing to rotate to 180 degrees. In addition, when the second beam unit 120 is rotated relative to the first beam assembly 100 to the horizontal unfolded state, the first end surface of the second beam unit 120 facing the first beam unit 110 abuts against the second end surface of the first beam unit 110 facing the second beam unit 120, so as to limit the second hinged unit 220 from continuing to rotate.

[0068] In some embodiments, referring to Figure 2 , Figure 6 and Figure 7, the first hinge unit 210 and the second hinge unit 220 are respectively arranged on the top side of the first cross beam unit 110 and the top side of the second cross beam unit 120, the first abutting surface 213 is a plane perpendicular to the top side of the first cross beam unit 110, and the second abutting surface 2211 is a plane parallel to the top side of the second cross beam unit 120. It can be understood that, in other embodiments of the present application, the first hinge unit 210 also abuts against and limits the position of the second cross beam unit 120 in the plane, or the second hinge unit 220 also abuts against and limits the position of the first cross beam unit 110 in the plane, which is not limited herein.

[0069] In some embodiments, referring to Figure 7 and Figure 8 , the first locking assembly 300 includes a first clamping part 311 arranged on the first hinge unit 210 and a second clamping part 331 arranged on the second hinge unit 220; in the folded state, the first clamping part 311 and the second clamping part 331 are elastically clamped.

[0070] Among them, the first clamping part 311 and the second clamping part 331 are elastically clamped, which can be that at least one of the first clamping part 311 and the second clamping part 331 itself has elasticity, so that the first clamping part 311 and the second clamping part 331 are elastically clamped. Or, at least one of the first clamping part 311 and the second clamping part 331 can be connected with an elastic member, so that the first clamping part 311 and the second clamping part 331 are elastically clamped under the elastic force of the elastic member.

[0071] When the second cross beam unit 120 rotates relative to the first cross beam unit 110 to the folded state, the second clamping part 331 moves with the second cross beam unit 120 to elastically clamp with the first clamping part 311, thereby locking the second cross beam unit 120 in the folded state. At the same time, since the first clamping part 311 and the second clamping part 331 are elastically clamped, an external force can be used to overcome the elastic clamping force of the first clamping part 311 and the second clamping part 331 to separate the first clamping part 311 and the second clamping part 331, so that the rotation and unfolding of the second cross beam unit 120 can be realized.

[0072] In some embodiments, referring to Figure 7 and Figure 8 , the first locking assembly 300 includes a first clamping part 311 arranged on the first hinge unit 210 and a second clamping part 331 arranged on the second hinge unit 220; in the folded state, the first clamping part 311 and the second clamping part 331 are elastically clamped.

[0073] When the second beam unit 120 is rotated to the folded state, the second clamping part 331 is clamped with the first clamping part 311, and the first elastic member 320 keeps the first clamping part 311 clamped with the second clamping part 331. When unfolding is needed, the first clamping part 311 can be separated from the second clamping part 331 by pressing the first clamping member 310 to overcome the elastic force of the first elastic member 320 on the first clamping part 311.

[0088] In some embodiments, referring to Figure 9 and Figure 10The first locking unit 410 comprises two movable members 412 movably arranged in the first lock seat 411, and a second elastic member 413 connected between the two movable members 412. The first lock seat 411 is provided with two buttons 414 connected with the two movable members 412 respectively. The two movable members 412 can clamp the lock tongue 422 under the elastic force of the second elastic member 413. Pressing the two buttons 414 can drive the two movable members 412 to move to release the lock tongue 422. Through the arrangement of the two movable members 412, the two movable members 412 can clamp the lock tongue 422 together to ensure stable locking. The arrangement of the two buttons 414 makes it easy to unlock the first locking assembly 300 by pressing the two buttons 414, which is simple and labor-saving.

[0089] Preferably, the two buttons 414 are arranged on opposite sides of the first lock seat 411, so that the user can press the two buttons 414 with two fingers of one hand, that is, one-handed operation is possible, which is convenient and easy to apply force. Of course, in other embodiments, the button 414 can be integrally connected with the movable member 412, that is, a part of the movable member 412 extends out of the surface of the first lock seat 411 as the button 414. In addition, in other embodiments, the number of movable members 412 and buttons 414 can be one, which is not limited here.

[0090] In some embodiments, the first lock seat 411 is provided with a second rotating shaft 415, and the two movable members 412 are rotatably arranged on the second rotating shaft 415. The second elastic member 413 is a torsion spring, and the second elastic member 413 is sleeved on the second rotating shaft 415. The opposite ends of the second elastic member 413 are connected with the two movable members 412 respectively. The first ends of the two movable members 412 are connected with the two buttons 414 respectively, and the second ends of the two movable members 412 are close to each other under the action of the torsion spring to clamp the lock tongue 422. Pressing the two buttons 414 can push the second ends of the two movable members 412 to move close to each other, so that the first ends of the two movable members 412 move away from each other to release the lock tongue 422. It can be understood that in other embodiments of the present application, the two movable members 412 can be slidably arranged in the first lock seat 411, and the second elastic member 413 can be a cylindrical spring, which is not limited here.

[0091] In some embodiments, please refer to Figure 9 and Figure 10The second locking unit 420 comprises a second locking seat 421, the locking tongue 422 comprises a connecting portion 4221 and a plug-in portion 4222, the connecting portion 4221 extends from the second locking seat 421 to the first locking seat 411, the plug-in portion 4222 is formed on the side of the connecting portion 4221 away from the second locking seat 421, the plug-in portion 4222 is triangular, the width of the plug-in portion 4222 gradually decreases from the connecting portion 4221 to the direction away from the connecting portion 4221, the maximum width of the plug-in portion 4222 is greater than the width of the connecting portion 4221, and a step surface is formed at the joint of the plug-in portion 4222 and the connecting portion 4221. The second end of the movable piece 412 has a hook portion 4121. When the second cross beam unit 120 is parallelly unfolded relative to the first cross beam unit 110, the plug-in portion 4222 of the locking tongue 422 is inserted into the second locking seat 421 and between the second ends of the two movable pieces 412, and under the action of the second elastic piece 413, the hook portions 4121 of the two movable pieces 412 hook the step surfaces on the two sides of the plug-in portion 4222, thereby preventing falling.

[0092] Specifically, the second locking seat 421 is fixed on the bottom side of the second cross beam unit 120 by screw locking.

[0093] Specifically, the first locking seat 411 comprises a seat body 4111 and an upper cover 4112, the second rotating shaft 415, the two movable pieces 412 and the second elastic piece 413 are all installed on the seat body 4111, the upper cover 4112 is buckled on the seat body 4111 and covers the second rotating shaft 415, the two movable pieces 412 and the second elastic piece 413, and the two buttons 414 are respectively installed on the upper cover 4112. The first locking seat 411 is divided into the seat body 4111 and the upper cover 4112, which facilitates the disassembly and assembly of the second rotating shaft 415, the two movable pieces 412 and the second elastic piece 413.

[0094] In some embodiments, referring to Figure 2 and Figure 7 The mounting bracket 1 further comprises a damping assembly 500 connected between the first cross beam unit 110 and the second cross beam unit 120 and used for slowing down the rotating speed of the second cross beam unit 120 relative to the first cross beam unit 110, thereby reducing the damage to the hinged assembly 200 caused by the sudden upward rotation of the second cross beam unit 120.

[0095] Specifically, referring to Figure 7The damping assembly 500 comprises a first connecting rod 510, a damping structure 520 and a second connecting rod 530. The first connecting rod 510 is connected with opposite ends of the damping structure 520 respectively. The damping structure 520 is capable of being stretched and contracted. An end of the first connecting rod 510 away from the damping structure 520 is connected with the first beam unit 110. An end of the second connecting rod 530 away from the damping structure 520 is connected with the second beam unit 120. The damping structure 520 comprises but is not limited to a damping elastic member and always has a tendency of being stretched. During the process that the second beam unit 120 rotates upward relative to the first beam unit 110 to the folding state, the damping assembly 500 always has a damping to the second beam unit 120 to prevent the second beam unit 120 from rotating upward, thereby simplifying the rotation speed of the second beam unit 120 and reducing the damage to the hinged assembly 200 caused by the sudden upward rotation of the second beam unit 120.

[0096] In some embodiments, the damping assembly 500 is arranged obliquely. The position where the damping assembly 500 is connected with the first beam unit 110 is lower than the position where the damping assembly 500 is connected with the second beam unit 120, so that the damping assembly 500 has an upward pushing force to the second beam unit 120.

[0097] In some embodiments, referring to Figure 2 , Figure 11 and Figure 12 , the mounting device 600 comprises a mounting plate 610 slidingly arranged on the beam assembly 100, an elastic pressing group 630 arranged on the mounting plate 610 and a pushing lever 640 rotatably arranged on the mounting plate 610. The elastic pressing group 630 is elastically abutted against the beam assembly 100. The pushing lever 640 is capable of driving the elastic pressing group 630 to release the beam assembly 100.

[0098] The mounting plate 610 is used for mounting a calibration element. For example, the calibration element is directly mounted on a mounting plate 610. For another example, two mounting plates 610 are used to mount a large-size calibration element together. The mounting plate 610 is also used for mounting and bearing the elastic pressing group 630 and the pushing lever 640.

[0099] When the mounting device 600 is adjusted to a position on the beam assembly 100, the elastic pressing group 630 is elastically abutted against the beam assembly 100, so as to lock the mounting device 600 at the current position. When it is necessary to adjust the position of the mounting device 600, the pushing lever 640 is pushed to drive the elastic pressing group 630 to release the beam assembly 100, so that the mounting device 600 can slide on the beam assembly 100 to adjust the position.

[0100] In this embodiment, the elastic pressing group 630 is arranged on the mounting plate 610, so that the elastic pressing group 630 elastically abuts against the beam assembly 100 to lock the mounting plate 610 at the current position, thereby ensuring the mounting stability of the mounting device 600 to the calibration element. The elastic pressing group 630 is released from the beam assembly 100 by simply rotating the lever 640, so that the mounting device 600 can slide on the beam assembly 100 to adjust the position, which is simple and labor-saving.

[0101] In some embodiments, referring to Figure 11 and Figure 13 , the lever 640 has oppositely arranged abutting end 644 and force applying end 645, wherein the abutting end 644 is used to abut against the elastic pressing group 630, and the force applying end 645 is used to be driven by the user; the force applying end 645 of the lever 640 has a first distance to the rotation center O1 thereof, and the abutting end 644 of the lever 640 has a second distance to the rotation center O1 thereof, and the first distance is greater than or equal to the second distance. The above arrangement makes the power arm of the lever 640 much greater than or equal to the resistance arm, so that the lever 640 is driven labor-savingly.

[0102] Preferably, the first distance can be 3 times, 4 times, 5 times, 6 times or more than 6 times of the second distance, so that the lever 640 is driven more labor-savingly.

[0103] In some embodiments, referring to Figures 11 to 13 , the force applying end 645 is provided with a holding ball 643, and the outer diameter of the holding ball 643 is greater than the outer diameter of the force applying end 645. The holding ball 643 can increase the contact area of the user, and the greater the contact area, the more labor-saving, and the user can hold it comfortably.

[0104] Optionally, the holding ball 643 can be made of hard material. Meanwhile, in order to improve the holding comfort, a soft rubber layer can be arranged on the surface of the holding ball 643.

[0105] In some embodiments, referring to Figures 11 to 13 , the abutting end 644 has two oppositely and spaced abutting portions 6423; in the locked state, the two abutting portions 6423 abut against the elastic pressing group 630 respectively; when the lever 640 rotates forward, one of the abutting portions 6423 abuts against and drives the elastic pressing group 630; when the lever 640 rotates reversely, the other abutting portion 6423 abuts against and drives the elastic pressing group 630.

[0106] It should be noted that the above locked state refers to the state that the elastic pressing group 630 abuts against the beam assembly 100, and at this time, the two abutting portions 6423 abut against the elastic pressing group 630 respectively, but have no pressing force on the elastic pressing group 630.

[0107] In addition, it should be noted that the forward and reverse directions herein do not have a specific direction, but refer to two opposite rotation directions. For example Figure 5 When the dial lever 640 is rotated clockwise, the right abutting portion 6423 always abuts against the elastic pressing group 630 and drives the elastic pressing group 630 to loosen the cross beam assembly 100, and at this time, the left abutting portion 6423 is raised upward. When the dial lever 640 is rotated counterclockwise, the left abutting portion 6423 always abuts against the elastic pressing group 630 and drives the elastic pressing group 630 to loosen the cross beam assembly 100, and at this time, the right abutting portion 6423 is raised upward.

[0108] In summary, the present application sets two spaced abutting portions 6423 at the abutting end 644, so that the dial lever 640 can drive the elastic pressing group 630 to loosen the cross beam assembly 100 when it is dialled forward and reverse, which is convenient for users to operate at different positions and saves labor. It can be understood that in other embodiments of the present application, the abutting end 644 can also include one abutting portion 6423, which is not limited herein.

[0109] Optionally, the abutting portion 6423 is arc-shaped, which can reduce the scratching of the elastic pressing group 630 when the abutting portion 6423 rotates.

[0110] In some embodiments, referring to Figure 13 The dial lever 640 includes a rod 641 and an abutting member 642, the abutting member 642 includes a first connecting segment 6421 and a second connecting segment 6422 which are connected vertically, the first connecting segment 6421 is rotatably arranged on the mounting plate 610, the bottom end of the rod 641 is connected with the first connecting segment 6421, and the top end of the rod 641 has a holding ball 643; two abutting portions 6423 are formed at opposite ends of the side of the second connecting segment 6422 away from the first connecting segment 6421. The dial lever 640 is divided into the rod 641 and the abutting member 642, so that the length of the rod 641 can be long enough, and at the same time, the abutting member 642 can be designed to be connected with the rod 641, the mounting plate 610 and the elastic pressing group 630 respectively.

[0111] Specifically, the end of the first connecting segment 6421 away from the second connecting segment 6422 has a socket, and the bottom end of the rod 641 is inserted into the socket.

[0112] Specifically, the first connecting segment 6421 and the second connecting segment 6422 are connected vertically at the central position.

[0113] In some embodiments, referring to Figure 11The mounting device 600 also includes a third rotating shaft 650, one end of the third rotating shaft 650 is fixed to the mounting plate 610, and the toggle lever 640 is rotatably provided at the other end of the third rotating shaft 650, specifically the first connecting section 6421 of the abutment member 642 is rotatably provided at the other end of the third rotating shaft 650.

[0114] In some embodiments, see Figure 11 and Figure 14 The elastic pressing group 630 includes a mounting seat 631, a third elastic member 632 mounted on the mounting seat 631, and a pressure plate 633 abutting against the third elastic member 632. The pressure plate 633 abuts against the beam assembly 100 under the elastic force of the third elastic member 632; the toggle lever 640 is used to overcome the elastic force of the third elastic member 632 and push the pressure plate 633 so that the pressure plate 633 releases the beam assembly 100.

[0115] The third elastic member 632 allows the pressure plate 633 to elastically abut against the cross-beam assembly 100, thereby locking the mounting device 600 in its current position. To adjust the position of the mounting device 600, the lever 640 can be toggled to overcome the elastic force of the third elastic member 632, causing the pressure plate 633 to release from the cross-beam assembly 100.

[0116] In some embodiments, the mounting base 631 includes two mounting plates 6311 and a guide rod 6312 connected between the two mounting plates 6311. The third elastic member 632 and the pressure plate 633 are respectively sleeved on the guide rod 6312, and the third elastic member 632 abuts between the pressure plate 633 and one of the mounting plates 6311. The two mounting plates 6311 and the guide rod 6312 can support and guide the third elastic member 632 and the pressure plate 633, allowing the third elastic member 632 to extend and retract along a straight line and the pressure plate 633 to slide straightly. The pressure applied by the pressure plate 633 to the beam assembly 100 is vertical, and when the lever 640 is rotated to push the pressure plate 633, the pressure plate 633 can also slide.

[0117] In some embodiments, see Figure 14The mounting seat 631 comprises two guide rods 6312 arranged at intervals, two mounting plates 6311 are arranged at intervals in opposition, and the two guide rods 6312 are connected between the two mounting plates 6311 respectively. A third elastic member 632 is sleeved on each guide rod 6312, and a pressing plate 633 is sleeved on each guide rod 6312. The arrangement of the two guide rods 6312 and the two third elastic members 632 can enable the large-area pressing plate 633 to slide smoothly, and can make the pressing force of the pressing plate 633 on the beam assembly 100 be distributed uniformly. Understandably, in other embodiments of the present application, the number of the guide rods 6312 and the third elastic members 632 can also be one, three or more than three, which is not limited herein.

[0118] Optionally, the third elastic member 632 is a cylindrical spring or a spring sheet.

[0119] In some embodiments, referring to Figure 11 The mounting plate 6311 is limited in the limiting groove 611 and is fixed to the limiting groove 611 by a fastener. The arrangement of the limiting groove 611 can limit the mounting plate 6311, so as to facilitate the subsequent locking of the mounting plate 6311 to the mounting plate 610 by the fastener.

[0120] Specifically, the limiting groove 611 is recessed on the side of the mounting plate 610 facing the beam assembly 100, and the limiting groove 611 penetrates one of the peripheral side surfaces of the mounting plate 610. During assembly, the mounting plate 6311 can be slid into the limiting groove 611 from the side opening of the limiting groove 611. The above arrangement facilitates the assembly of the mounting plate 6311 and simplifies the processing difficulty of the limiting groove 611.

[0121] Optionally, referring to Figure 14 The two mounting plates 6311 are a bottom mounting plate 6311a and a top mounting plate 6311b respectively. The horizontal dimension of the bottom mounting plate 6311a is greater than that of the top mounting plate 6311b. The bottom mounting plate 6311a is limited in the limiting groove 611 and is locked to the mounting plate 610 by a fastener. The top mounting plate 6311b is arranged in opposition to the bottom mounting plate 6311a and is connected by the guide rod 6312, that is, the top mounting plate 6311b is not connected to the mounting plate 610. This can simplify the structure of the mounting plate 610 and the installation difficulty of the top mounting plate 6311b, so that the top mounting plate 6311b only needs to meet the assembly requirement of the guide rod 6312, and the machining precision requirement of the top mounting plate 6311b is reduced. Understandably, in other embodiments of the present application, the above two mounting plates 6311 are mounted on the mounting plate 610, which is not limited herein.

[0122] In some embodiments, please refer to Figure 14 The pressing plate 633 is provided with a buffer pad 634 on one side of the crossbeam assembly 100. The buffer pad 634 can reduce the sliding scratch of the pressing plate 633 on the crossbeam assembly 100.

[0123] In some embodiments, please refer to Figure 2 and Figure 15 The side of the crossbeam assembly 100 is provided with a guide rail 130 of a sliding groove 133. The mounting plate 610 is connected with a sliding block 660 which is slidably arranged in the sliding groove 133. The elastic pressing group 630 is elastically abutted to the outside of the guide rail 130. Specifically, the guide rail 130 is arranged on the side of the crossbeam assembly 100 facing the mounting plate 610. The guide rail 130 not only realizes the sliding guidance of the mounting plate 610, but also is used for the elastic abutment of the elastic pressing group 630.

[0124] Specifically, the guide rail 130 includes a clamping plate 131 clamped to the crossbeam assembly 100 and side plates 132 formed on the upper and lower sides of the clamping plate 131. The clamping plate 131 and the two side plates 132 extend along the length extension direction of the crossbeam assembly 100. The clamping plate 131 is clamped to the crossbeam assembly 100. The clamping plate 131 and the two side plates 132 enclose the above-mentioned sliding groove 133. The elastic pressing group 630 is elastically abutted to the outside of one of the side plates 132.

[0125] In some embodiments, please refer to Figure 15 The connecting plate 670 is further connected between the sliding block 660 and the mounting plate 610. The connecting plate 670 is clamped to the mounting plate 610 by screws. The sliding block 660 is clamped to the connecting plate 670 by screws. The connecting plate 670 is arranged so that the sliding block 660 can be made of a material resistant to friction. At the same time, the sliding block 660 is convenient to disassemble and replace.

[0126] Optionally, the elastic pressing group 630 and the connecting plate 670 are spaced apart along the length extension direction of the crossbeam assembly 100 on the mounting plate 610.

[0127] In some embodiments, please refer to Figure 11 The opposite sides of the two mounting plates 610 of the two first mounting devices 600a are provided with vertically penetrating insertion slots 612. The insertion slots 612 are arranged to facilitate the clamping mounting of the first calibration element.
