In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise specifically limited.

[0033] Please refer to Figures 1 to 5The beam mounting structure 600 provided by the embodiment of the present application will be described. The beam mounting structure 600 is applied to an automobile measuring device, and is slidably arranged on the beam assembly 100 to fix a calibration element for calibrating or calibrating an automobile sensor, for example, to fix a radar calibration device, or to fix a target for calibration or calibration.

[0034] The beam mounting structure 600 comprises a mounting plate 610 slidably arranged on the beam assembly 100, an elastic pressing group 630 arranged on the mounting plate 610, and a toggle lever 640 rotatably arranged on the mounting plate 610; the elastic pressing group 630 elastically abuts against the beam assembly 100, and the toggle lever 640 can drive the elastic pressing group 630 to release the beam assembly 100.

[0035] The mounting plate 610 is used to mount the calibration element, for example, the calibration element is directly mounted on one mounting plate 610, or two mounting plates 610 are used to mount a large-size calibration element. The mounting plate 610 is also used to mount and support the elastic pressing group 630 and the toggle lever 640.

[0036] When the position of the beam mounting structure 600 on the beam assembly 100 is adjusted, the elastic pressing group 630 elastically abuts against the beam assembly 100, so as to lock the beam mounting structure 600 at the current position; when it is necessary to adjust the position of the beam mounting structure 600, the toggle lever 640 is toggled to drive the elastic pressing group 630 to release the beam assembly 100, so that the beam mounting structure 600 can slide on the beam assembly 100 to adjust the position.

[0037] The beam mounting structure 600 in the embodiment of the present application can lock the mounting plate 610 at the current position by arranging the elastic pressing group 630 on the mounting plate 610, so that the elastic pressing group 630 elastically abuts against the beam assembly 100, thereby ensuring the mounting stability of the beam mounting structure 600 to the calibration element. By arranging the toggle lever 640, the elastic pressing group 630 can be released from the beam assembly 100 by simply toggling the toggle lever 640, so that the beam mounting structure 600 can slide on the beam assembly 100 to adjust the position, which is simple and labor-saving.

[0038] In some embodiments, please refer to Figure 4 and Figure 6The toggle lever 640 has an abutting end 644 and a force applying end 645 arranged oppositely, 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 toggle lever 640 has a first distance to the rotation center O1 of the toggle lever 640, and the abutting end 644 of the toggle lever 640 has a second distance to the rotation center O1 of the toggle lever 640, and the first distance is greater than or equal to the second distance. The above arrangement makes the power arm of the toggle lever 640 greater than or equal to the resistance arm, so that the driving of the toggle lever 640 is labor-saving.

[0039] 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 driving of the toggle lever 640 is more labor-saving.

[0040] In some embodiments, referring to Figures 4 to 6 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 arrangement of 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 comfortably.

[0041] 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.

[0042] In some embodiments, referring to Figures 4 to 6 The abutting end 644 has two abutting portions 6423 arranged oppositely and spaced apart; in the locking state, the two abutting portions 6423 abut against the elastic pressing group 630 respectively; when the toggle lever 640 rotates forward, one of the abutting portions 6423 abuts against and drives the elastic pressing group 630; when the toggle lever 640 rotates reversely, the other abutting portion 6423 abuts against and drives the elastic pressing group 630.

[0043] It should be noted that the above locking state refers to the state that the elastic pressing group 630 abuts against the cross 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.

[0044] In addition, it should be noted that the forward and reverse directions herein have no specific direction, and only refer to two opposite rotation directions. For example Figure 5 In the embodiment, when the toggle lever 640 rotates clockwise, the right abutting portion 6423 always abuts against and drives the elastic pressing group 630 to release the cross beam assembly 100, and at this time, the left abutting portion 6423 is upturned; when the toggle lever 640 rotates reversely, the left abutting portion 6423 always abuts against and drives the elastic pressing group 630 to release the cross beam assembly 100, and at this time, the right abutting portion 6423 is upturned.

[0045] In summary, the present application sets two spaced apart abutting portions 6423 at the abutting end 644, so that the dial lever 640 can be driven to drive the elastic pressing group 630 to release the cross beam assembly 100 by positive dialing and reverse dialing, facilitating the user to operate at different positions, convenient and labor-saving operation. 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 here.

[0046] Optionally, the abutting portion 6423 is arc-shaped, which can reduce the scratch of the elastic pressing group 630 when rotating.

[0047] In some embodiments, referring to Figure 6 , the dial lever 640 includes a rod 641 and an abutting piece 642, the abutting piece 642 includes a first connecting segment 6421 and a second connecting segment 6422 connected perpendicularly, 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 second connecting segment 6422 away from the first connecting segment 6421. Among them, the dial lever 640 is divided into the rod 641 and the abutting piece 642, so that the length of the rod 641 can be long enough, and at the same time the abutting piece 642 can be designed to be connected with the rod 641, the mounting plate 610 and the elastic pressing group 630 respectively.

[0048] 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.

[0049] Specifically, the first connecting segment 6421 is connected perpendicularly at the center position of the second connecting segment 6422.

[0050] In some embodiments, referring to Figure 4 , the cross beam mounting structure 600 further includes a rotating shaft 650, one end of the rotating shaft 650 is fixed to the mounting plate 610, and the dial lever 640 is rotatably arranged at the other end of the rotating shaft 650, specifically the first connecting segment 6421 of the abutting piece 642 is rotatably arranged at the other end of the rotating shaft 650.

[0051] In some embodiments, referring to Figure 4 and Figure 7 , the elastic pressing group 630 includes a mounting seat 631, an elastic piece 632 mounted on the mounting seat 631, and a pressing plate 633 abutting against the elastic piece 632, the pressing plate 633 abuts against the cross beam assembly 100 under the elastic force of the elastic piece 632; the dial lever 640 is used to push the pressing plate 633 to release the cross beam assembly 100 against the elastic force of the elastic piece 632.

[0052] The elastic member 632 is arranged such that the pressing plate 633 can elastically abut against the cross beam assembly 100, so that the pressing plate 633 can elastically abut against the cross beam assembly 100 to lock the cross beam mounting structure 600 at the current position of the cross beam assembly 100. When it is needed to adjust the position of the cross beam mounting structure 600, it is only needed to overcome the elastic force of the elastic member 632 by pulling the lever 640, so that the pressing plate 633 is released from the cross beam assembly 100.

[0053] In some embodiments, the mounting base 631 comprises two mounting plates 6311 and a guide rod 6312 connected between the two mounting plates 6311, the elastic member 632 and the pressing plate 633 are sleeved on the guide rod 6312 respectively, and the elastic member 632 abuts between the pressing plate 633 and one of the mounting plates 6311. The two mounting plates 6311 and the guide rod 6312 are arranged to support and guide the elastic member 632 and the pressing plate 633, so that the elastic member 632 can stretch and contract in a straight line, and the pressing plate 633 can also slide straightly, so that the pressing force of the pressing plate 633 against the cross beam assembly 100 is a vertical pressing force, and the pressing plate 633 can also slide when the lever 640 is rotated to push the pressing plate 633.

[0054] In some embodiments, referring to Figure 7 , the mounting base 631 comprises two spaced guide rods 6312, and the two mounting plates 6311 are spaced relative to each other, and the two guide rods 6312 are connected between the two mounting plates 6311 respectively, and each guide rod 6312 is sleeved with an elastic member 632, and the pressing plate 633 is sleeved on the two guide rods 6312. The two guide rods 6312 and the two elastic members 632 are arranged to enable the large-area pressing plate 633 to slide smoothly, and to uniformly distribute the pressing force of the pressing plate 633 against the cross beam assembly 100. It can be understood that in other embodiments of the present application, the number of guide rods 6312 and elastic members 632 can also be one, three or more than three, which is not limited herein.

[0055] Optionally, the elastic member 632 is a cylindrical spring or a spring sheet.

[0056] In some embodiments, referring to Figure 4 , the mounting plate 610 has at least one limiting slot 611, and the at least one mounting plate 6311 is limited in the limiting slot 611 and is fixed in the limiting slot 611 by a fastener. The limiting slot 611 is arranged to limit the mounting plate 6311, so as to facilitate subsequent locking of the mounting plate 6311 to the mounting plate 610 by the fastener.

[0057] 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.

[0058] Optionally, referring to Figure 7 , 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 locked to the mounting plate 610 by fasteners. The top mounting plate 6311b is arranged in opposite spaced relation to the bottom mounting plate 6311a and connected by the guide rod 6312, that is, the top mounting plate 6311b is not connected to the mounting plate 610. In this way, the structure of the mounting plate 610 can be simplified, and the installation difficulty of the top mounting plate 6311b is also simplified, so that the top mounting plate 6311b only needs to meet the assembly requirements of the guide rod 6312, thereby reducing the machining precision requirement of the top mounting plate 6311b. It can be understood that in other embodiments of the present application, the above two mounting plates 6311 are both mounted to the mounting plate 610, which is not limited herein.

[0059] In some embodiments, referring to Figure 7 , the pressing plate 633 is provided with a buffer pad 634 abutting against one side of the beam assembly 100. The provision of the buffer pad 634 can reduce the sliding scratches of the pressing plate 633 on the beam assembly 100.

[0065] In some embodiments, referring to Figure 8 , the mounting plate 610 is provided with a laser emitter 680 for emitting laser to a target and a battery 690 for supplying power to the laser emitter 680. When adjusting the lateral position of the crossbeam mounting structure 600, laser can be emitted to the target by the laser emitter 680, which facilitates the operator to determine the position of the crossbeam mounting structure 600 according to the laser.

[0066] Specifically, the mounting plate 610 is further provided with a control switch 700, and the control switch 700 is used to control the battery 690 to supply power to the laser emitter to realize laser emission.

[0067] Optionally, the laser emitter 680 is a point laser.
