Optionally, the left cross-beam portion 32 and the right cross-beam portion 34 can be rotated relative to the connecting portion 36, for example, they can be folded together downward, or can be folded upward, forward, and backward together. Optionally, when the left cross beam portion 32 and the right cross beam portion 34 are folded down, the length of the connecting portion 36 can be relatively short, and the left cross beam portion 32 and the right cross beam portion 34 are in a drooping state, so that the cross beam assembly 30 can be removed from When the stand assembly 20 is removed, the space occupied by the calibration bracket 100 will also be significantly reduced, which can be conveniently carried by means of transportation.

The base 10' includes a base body 12', a roller 14', a height adjusting member 16' and a pull ring 18'.

The base body 12' has a triangular claw shape and includes three claws, each of which extends in three different directions. The base body 12' can be made of metal materials.

The roller 14' is mounted on the bottom surface of the base body 12', the number of the roller 14' may be three, and each roller 14' is mounted on the end of a corresponding claw for It is convenient to move the base body 12'. In this embodiment, the roller 14' is a universally movable roller, so that the base body 12' can move arbitrarily back and forth, left and right.

Compared with the prior art, the embodiment of the present invention provides a calibration bracket 100' in which the adjacent beams 310' are folded and connected in a horizontal plane. After the beams 31' are folded, the length L of the beams 31' becomes shorter , So that the calibration bracket 100' is easy to carry.

In some embodiments, referring to FIG. 12, the base body 12 is further provided with a recess 122, and the two claw portions are respectively located on opposite sides of the recess 122 and are symmetrical with respect to the recess 122. Referring to FIG. 13, when the calibration bracket 100 is aligned with the car, the multi-line laser 200 is installed on the beam assembly 30, and the multi-line laser 200 emits two sectors of light 210 perpendicular to the ground and perpendicular to each other and intersecting. The light rays 210 from the two sectors pass through the recess 122 to align with the cross mark 220 on the ground. The recess 122 is provided on the base body 12, which has a simple structure and can also facilitate the alignment of the calibration bracket 100 to the car. It can be understood that the recess 122 is used in a situation where the intersection formed by two intersecting and perpendicular laser lines is used to position the calibration bracket 100. When the base body 12 has other shapes, depressions or holes can be similarly provided in the corresponding positions of the base body 12, so that the intersection of laser lines used for positioning the calibration bracket 100 can be hit on the ground.

14 and 22 together, the stand assembly 20 may include a fixed stand bar 22, a movable stand bar 24 and a driving mechanism 26, the moving stand bar 24 is sleeved in the fixed stand bar 22, so The movable vertical rod 24 can move relative to the fixed vertical rod 22 along the length direction of the fixed vertical rod 22, and the driving mechanism 26 is installed on the fixed vertical rod 22 for driving the movable vertical rod 24 along The length direction of the fixed upright rod 22 moves relative to the fixed upright rod 22.

The cross beam assembly 30 is installed on the top surface of the movable vertical rod 24, which makes the center of gravity of the cross beam assembly 30 closer to the center of gravity of the vertical frame assembly 20 compared with the traditional calibration frame, which can increase the stability of the calibration frame, and The base body 12 with a smaller area can be used.

Using the way that the movable vertical rod 24 and the fixed vertical rod 22 are sleeved and connected, the height of the vertical frame assembly 20 can be reduced to nearly half of the original height. With the folding of the cross-bar assembly 30, the vertical frame assembly 20 can be very suitable for placement in automobiles, etc. Carry it in the trunk of the vehicle.

It can be understood that, if necessary, the fixed vertical rod can be used as the inner rod, and the movable vertical rod can be used as the outer rod. The driving mechanism 26 is installed on the fixed vertical rod 22 to drive the movable vertical rod 24 along the fixed vertical rod 22. The length direction of φ moves relative to the fixed pole 22.

Optionally, the fixed upright pole 22 and the movable upright pole 24 are respectively square-shaped, and the movable upright pole 24 is tightly sleeved in the fixed upright pole 22, so that the movable upright pole 24 is only It can move relative to the fixed stand 22 along the length direction of the fixed stand 22, and can prevent the movable stand 24 from moving in other directions relative to the fixed stand 22. This configuration is very important for the calibration bracket 100 to be foldable, because in the calibration process, it is usually necessary to use the fixed relative position relationship between the components of the calibration bracket 100. For example, it is possible to fix a laser on the outer surface of the fixed pole 22 The laser is used to locate the center axis of the vehicle, so as to determine the relative position between the target carried on the beam assembly 30 and the vehicle. Therefore, if the relative position of each component changes slightly, the calibration accuracy will be affected, or an additional fine-tuning mechanism needs to be added to compensate. If the relative position of each component changes greatly, it may cause the additional fine-tuning mechanism to fail. Therefore, in the telescopic mode, the relative movement between the movable vertical rod 24 and the fixed vertical rod 22 except along the length direction, such as relative rotation, needs to be eliminated. A simple method is to move the vertical rod 24 and the fixed vertical rod 22 as a square pass, which can ensure that only relative movement along the length occurs between the two.

It is understandable that, in some other embodiments, the fixed upright rod 22 and the movable upright rod 24 may also be pipes of other shapes, for example, pipes with mutually matched polygonal cross-sections, which can make the movable vertical The rod 24 can only move relative to the fixed vertical rod 22 along the length direction of the fixed vertical rod 22, and can prevent the movable vertical rod 24 from moving in other directions relative to the fixed vertical rod 22. Here, “cooperating with each other” does not necessarily require that the cross-sections of the fixed upright 22 and the movable upright 24 must be the same. For example, the cross-section of the fixed upright 22 arranged outside may be hexagonal, and the cross-section of the movable upright 24 arranged inside may be Being a quadrilateral connected with the hexagon, the effect that the movable vertical rod 24 can only move relative to the fixed vertical rod 22 along the length direction of the fixed vertical rod 22 can also be achieved. The cross section of the fixed upright 22 and the movable upright 24 can also be elliptical cylindrical pipes that cooperate with each other, and the elliptical cross section can also restrict relative rotation between the two to a certain extent.

When the cross sections of the fixed vertical rod and the movable vertical rod are non-circular, it is equivalent to using the entire tube wall of the fixed vertical rod as a guide rail to guide the moving direction of the movable vertical rod.

The fixed upright rod 22 and the movable upright rod 24 may also be cylindrical pipes with a circular cross-section. At this time, a guide mechanism can be used to prevent the fixed upright rod 22 from rotating relative to the movable upright rod 24. To guide the movable pole 24 to move stably relative to the fixed pole 22, or to add a mechanism for detecting and adjusting the movement of the fixed pole 22 relative to the movable pole 24 in the longitudinal direction at other parts of the calibration bracket 100 . A simple guide mechanism is a guide rail and a sliding block device matched with it. A guide rail can be set on one of the fixed vertical rod 22 and the movable vertical rod 24 at the contact surface, and the other Slider devices such as bumps, plastic rubber strips, rollers, balls, gears, etc. are set on the upper side. At this time, the slider device will be restricted to move on the guide rail, and it can also ensure that only the relative length between the two poles occurs. movement. The guide rail can be a groove, a linear protrusion, a rack, etc. additionally arranged on the wall of the vertical rod, or a groove, a linear protrusion, or between two linear protrusions formed on the wall of the vertical rod. The formed grooves, that is, the vertical rod uses a special-shaped tube wall, and the shape of the tube wall itself has grooves, linear protrusions and other parts that can be used as guide rails. Similarly, the slider device may be an additional component that is additionally provided on the wall of the vertical rod, or it may be a protruding structure formed by the wall of the vertical rod itself, without the need to provide additional components on the wall of the vertical rod. In addition, racks and other mechanisms that achieve transmission through meshing also have a guiding effect, and this specification also includes them in the category of guide rails. The gear and rack transmission mechanism described in the following embodiments can also achieve the guiding effect. Optionally, the rack can be arranged in the groove guide rail.

It is understandable that the setting positions of the guide rail and the sliding block device can be interchanged, the guide rail can be arranged on the movable vertical pole, the sliding block device can be arranged on the fixed vertical pole, or can be exchanged.

It is understandable that the guiding mechanism is not limited to the fixed vertical rod 22 and the movable vertical rod 24 with a circular cross-section, and the fixed vertical rod 22 and the movable vertical rod 24 with other cross-sectional shapes may also use guiding mechanisms to enhance the guiding effect, and Obtain more stable or less frictional relative movement. For non-circular cross-sectional shapes, it is also possible not to use guide rails, and only use linear motion devices to obtain a more stable or less frictional relative movement. At this time, the non-circular external pole itself plays a guiding role.

It can be understood that, in addition to the guide rail and the sliding block device, the connection between the fixed vertical rod 22 and the movable vertical rod 24 can also be implemented in other ways.

In the following, a connection structure between the fixed vertical rod and the movable vertical rod will be described in detail with reference to the accompanying drawings. In the following description, the fixed vertical rod 22 may be referred to as an "outer tube", and the movable vertical rod 24 may be It is called "inner casing".

Abuts against the inner surface of the outer sleeve 18M. The fixed ball assembly 12M and the floating ball assembly 14M are respectively located on opposite sides of the inner sleeve 16M; during installation, the protruding part of the fixed ball assembly 12M abuts one side of the outer sleeve 18M, so The protruding part of the floating ball assembly 14M abuts against the opposite side of the outer sleeve 18. Since the protruding part of the fixed ball assembly 12M cannot be contracted or stretched, it can play a role in positioning during installation. Because the protruding part of the floating ball assembly 14M can shrink Or stretch, so it is convenient to sleeve the outer sleeve 18M in the inner sleeve 16M, and play a role in facilitating installation. At the same time, because the protruding parts of the fixed ball assembly 12M and the floating ball assembly 16M always abut on the outer sleeve The inner surface of the tube 18M can eliminate the gap between the inner sleeve 16M and the outer sleeve 18M, and can avoid large-scale shaking. Each floating ball assembly 14M partially protrudes from the outer surface of the inner sleeve 16M, and the partially protruding floating ball assembly 14M can be elastically contracted or stretched, and it always abuts against the outer surface of the outer sleeve 18 The inner surface, so that the inner sleeve 16M always fits closely with the outer sleeve 18M, will not be stuck or loosened, can greatly reduce the processing accuracy of the inner sleeve and the outer sleeve, and realize mass production.

The drive gear 264b can only rotate about the second rotation axis A2 relative to the gear bearing 260b The driving gear 264b cannot move relative to the gear bearing 260b along the second rotation axis A2. The helical gear 268b, the gear bearing 260b, the driving gear 264b and the screw rod 262b are all located in the fixed upright 22b.

Rotating the handle 266b causes the helical gear 268b to rotate about the first rotation axis A1 to drive the driving gear 268b to rotate about the second rotation axis A2 relative to the gear bearing 260b. The driving gear 264b is threadedly engaged with the screw rod 262b. When the driving gear 264b rotates around the second rotation axis A2, the screw rod 262b can be driven to move along the second rotation axis A2, thereby driving the moving vertical rod 24b moves relative to the fixed upright 22b along the length direction of the fixed upright 22b.

It is understandable that the driving mechanism may also be provided with a gear stop mechanism, for example, a pawl stop device, etc., so that the movable pole can be stopped at a required position.

Similarly, the right cross beam portion 34 is provided with a second block 340 and a second guide rail 342. The second clamping block 340 and the second supporting rod 33 are both connected to the same side of the right cross beam portion 34. When the second supporting rod 33 rotates to be parallel to the right cross beam portion 34, the second clamping block The 340 is clamped into the second slot 3300 to clamp the second supporting rod 33 to the right cross beam portion 34.

It can be understood that, in some other embodiments, the first guide rail 322 and the second guide rail 342 may be provided on other surfaces of the beam, such as the top surface. In some other embodiments, the first guide rail 322 and the second guide rail 342 do not need to be provided, and the calibration element can be directly hung on the crossbeam using a hook or the like. The first guide rail 322 and the second guide rail 342 can also have other forms, which are not limited to those shown in the figure. For example, they can be one or more groove lines arranged on the top surface of the beam, and can be formed by the outer wall of the beam itself. The groove line does not need to install additional rails.

It can be understood that the number of the support rods is not limited by the foregoing embodiment. For example, there can be only one supporting rod and it is arranged at the approximate center of the connecting portion 36. At this time, the target located at the approximate center of the beam assembly 30 can also be lifted well. When the target used for calibration is located in other positions, the supporting rod can also be set in the corresponding position for lifting. The number of supporting rods can also be greater than two. In addition, the supporting rod can also be arranged on a supporting rod guide (not shown in the figure), which is arranged on the side or bottom surface of the beam assembly 30, so that the supporting rod can move along the assembled beam assembly 30 to Lift targets that may be in different positions in the right position.

It is understandable that when the guide rail is used to make the support rod movable, the support rod can also be clamped to the beam assembly 30 by means of a clamping block and a slot.

The limiting structure 3303 (see Figure 16) used for limiting can also be retained on the guide rail.

The connecting portion 36 of the beam is sleeved in the mounting seat 35, and the first surface 360 of the connecting portion 36 is recessed with positioning holes 3604. The number of positioning holes 3604 is preferably two, and two positioning holes 3604 is arranged along the length direction of the connecting portion 36.

Correspondingly, at the corresponding position of the mounting seat 35, a positioning mechanism adapted to the positioning hole 3604, such as a positioning post 3524, is provided (see FIG. 22). In addition, the connecting portion 36 and the mounting seat 35 can also be provided with other types of positioning mechanisms, for example, a positioning slot 3564 is provided on the mounting seat 35, and a corresponding positioning mechanism (not shown in the figure) is provided at the corresponding position of the connecting portion 36出), in order to more conveniently and accurately place the connecting portion 36 of the beam to the predetermined position of the mounting seat 35.

Referring to FIG. 17, the connecting portion 36 is provided with a fixing groove 3620, a fixing surface 3624 is provided in the fixing groove 3620, and the fixing groove 3620 is used in conjunction with the fixing rod 354 in FIG. 18 to fix the beam assembly in the installation Seat 35. Optionally, the fixing groove 3620 is provided so that the fixing surface 3624 and the bottom surface of the mounting seat 35 are at a certain angle. The advantages of this arrangement are explained in conjunction with the fixing rod 354 in FIG. 17. For example, the fixing groove 3620 may be arranged between the second surface 362 and the top surface of the beam, wherein the second surface 362 is arranged parallel to the first surface 360, and the fixing surface 3624 is connected to the first surface 360 and the second surface 362. An included angle, for example, the fixing surface 3624 and the first surface 360 and the second surface 362 are set at 45 degrees, or set at 30 degrees or 60 degrees.

In this embodiment, the left beam portion 32, the right beam portion 34, and the connecting portion 36 are all square-shaped, which can reduce the weight of the calibration bracket 100 and make the connecting portion 36 easy to be firmly sheathed In the adjustment mechanism 38. It can be understood that, in some other embodiments, the left beam portion 32, the right beam portion 34, and the connecting portion 36 may also be pipes of other shapes, special-shaped materials or rods, etc., for example, they may be polygonal or circular. Pipe or rod. When the beam is a pipe with other shapes, the fixing groove 3620 can be arranged at a position where the fixing surface 3624 and the bottom surface of the mounting seat 35 can be at a certain angle.

Please refer to FIG. 18 and FIG. 19, the mounting seat 35 is used to sleeve the connecting portion 36. The mounting base 35 includes a fixing member 352, a fixing rod 354 and a mounting shell 356.

Optionally, the mounting seat 35 may be provided on the adjusting mechanism 37, so that the mounting seat 35 can be rotated relative to the stand assembly 20 around the adjusting rotation axis L under the adjustment of the adjusting mechanism 37 to adjust The horizontal angle of the mounting base 35 and the beam assembly 30. Preferably, the adjustment mechanism 37 and the mounting seat are arranged in an up-and-down relationship, so as to facilitate the removal and installation of the beam from above while realizing horizontal angle adjustment. The adjustment rotation axis L is arranged parallel to the fixed upright rod 22 and the movable upright rod 24, that is, when the calibration bracket 100 is placed on a horizontal plane, the adjustment rotation axis L is arranged vertically. The mounting base 35 is provided with a notch 350 for facilitating putting the connecting part 36 into the mounting base 35 or removing the connecting part 36 from the mounting base 35.

The holding member 352 is generally hook-shaped to facilitate holding the connecting portion 36. One end of the holding member 352 is fixedly connected to the mounting shell 356, for example, mounted on the upper surface or side of the mounting shell 356, and the other end surrounds and grasps the connecting portion 36 of the beam assembly 20, leaving a gap 350. For example, the holder 352 may have the shape shown in FIG. 18, of course, it may also have other shapes, such as circular hook shape, other polygonal hook shape, circular ring and polygonal hook shape, as long as it can realize the connection part 36 The stable control is sufficient. The “substantially hook-shaped” mentioned here means that the holding member 352 can extend from a certain angle and a certain length, so as to support and hold the connecting portion 36.

The holding member 352 and the mounting shell 356 surround a mounting channel for receiving the connecting portion 36. The installation channel communicates with the gap 350. The inner surface of the holding member 352 is provided with positioning posts 3524, and the two positioning posts 3524 are located in the installation channel and are used to insert the two positioning holes 3604 (see FIG. 16) to facilitate the The connecting portion 36 is positioned in the installation channel. The function of the positioning hole 3604 is to further reduce any displacement of the beam assembly 20 relative to the mounting seat 35 in the horizontal direction during calibration. The positioning post 3524 may also be arranged on the upper surface of the mounting shell 356 or on both the upper surface of the mounting shell 356 and the inner surface of the holder 352. The "positioning post" herein includes round, square, and long positioning posts, and the "positioning hole" includes round, square, and long positioning holes. When the positioning posts and the positioning holes are roughly point-shaped, there are preferably at least two positioning posts 3524 along the length direction of the connecting portion 36 to ensure that the connecting portion 36 does not shift along the length direction. When the positioning post and the positioning hole are roughly elongated, only one pair of the positioning post and the positioning hole can be used. It is understandable that in some other embodiments, the positions of the positioning hole 3604 and the positioning post 3524 can be interchanged, that is, the positioning hole 3604 is opened in the holding member 352 and is connected to the mounting The channels are connected, and the positioning column 3524 is disposed on the first surface 360 (see FIG. 16).

Optionally, the fixing rod 354 is disposed on the holding member 352, which includes a knob and at least a section of screw, and cooperates with the thread of the holding member 352, when the connecting portion 36 is sleeved on the mounting seat At 35 o'clock, the central axis of the fixed rod 354 is perpendicular to the fixed surface 3624 at the beam connecting portion 36. Rotating the fixed rod 354 can make the fixed rod 354 abut the fixed surface 3624, so that the beam The connecting portion 36 of the assembly 30 is fixed to the mounting seat 35, or by rotating the fixing rod 354, the fixing rod 354 can be separated from the fixing surface 3624, and the connecting portion 36 can be removed from the fixing surface 3624 through the notch 350 The mounting base 35 is removed.

Optionally, the fixing surface 3624 and the bottom surface (ie, the horizontal plane) of the mounting base 35 are at a certain angle, and the fixing rod 354 and the bottom surface of the mounting base 35 are at a certain angle, the angle being greater than 0 degrees and less than 90 degrees. Optionally, the angle is approximately 45 degrees, and may also be approximately 30 degrees, 60 degrees, or any other angle between 0-90 degrees. In this arrangement, only one fixing rod 354 can be used to apply a pressing force to the connecting portion 36 toward the bottom surface and a side surface of the mounting seat, which is the side opposite to the extension direction of the fixing rod 354, thereby achieving The fixing seat is highly stable to fix the connecting portion 36, and the beam assembly can be easily disassembled and assembled.

It is understandable that the mounting base 35 may have other structures, for example, a notch may not necessarily be maintained. After the connecting portion 36 is placed in the mounting base 35, a baffle or the like can be used to block the notch. The connecting portion 36 can also be installed in other ways. For example, the mounting base 35 can be a complete ring structure with no gaps for inserting the beam. At this time, the beam can be assembled first, and then the mounting base 35 can be inserted. The fixing rod 354 is used to tighten and fix the beam.

It is understandable that the bottom surface or side surface of the mounting seat 35 pressed by the connecting portion 36 may be arc-shaped or other irregular shapes. At this time, the fixing rod 354 can also be used to press the connecting portion 36 on these surfaces. At this time, the fixed rod may be in line contact with these surfaces instead of surface contact, but it will not affect the pressing effect.

Optionally, when the mounting base 35 includes a notch 350, the surface of the mounting base 35 facing away from the notch 350 can also be used to mount a calibration element, for example, a multi-line laser 200 (see FIG. 1 and FIG. 5).

The multi-line laser 200 and the recess 122 on the base 12 are located on the same side of the surface of the mounting seat 35 facing away from the notch 350.

The mounting shell 356 is generally a cube with an opening on one side. The adjusting mechanism 37 is disposed in the opening of the mounting shell 356. The mounting shell 356 defines a threaded hole 3562, and a mounting post 3560 is provided in the mounting shell 356. The adjusting mechanism 37 includes a supporting shaft 371, a first elastic member 372, a rotating member 373, a bearing seat 374, a base 375 and an adjusting rod 376. The adjustment mechanism 37 is used to adjust the angle of the beam assembly 20 in the horizontal direction (ie, the yaw angle).

The supporting shaft 371 is received in the mounting shell 356 and fixedly installed on the inner wall of the mounting shell 356. The central axis of the support shaft 371 coincides with the adjustment rotation axis L.

One end of the first elastic member 372 is fixed to the mounting post 3560, and the other end of the first elastic member 372 is fixed to the rotating member 373. In this embodiment, the first elastic member 372 is a tension spring.

The rotating member 373 is substantially a cube, one end of which is provided with a protrusion 3732, and the protrusion 3732 and the first elastic member 372 are located on opposite sides of the rotating member 373, respectively. The rotating member 373 is sleeved on the bearing seat 374.

The bearing seat 374 is fixedly installed on a surface of the base 375, and the central axis of the bearing seat 374 coincides with the adjustment rotation axis L. The rotating member 373 is fixedly installed on the base 375 and sleeved on the bearing seat 374. One end of the supporting shaft 371 is inserted into the bearing housing 374, so that the supporting shaft 371 and the mounting shell 356 can be relative to the rotating member 373, the bearing housing 374 and the base 375 together about the adjustment rotation axis L Rotate.

The base 375 is used to be installed on the movable pole 24, and the movable pole 24 can drive the base 375 to rise or fall. In this embodiment, the base 375 is a cube, and the base 375 covers the opening of the mounting shell 356. The supporting shaft 371, the first elastic member 372 and the rotating member 373 are all contained in a cavity formed by the mounting shell 356 and the base 375.

The "cube" in this specification includes a thin plate shape.

The adjusting rod 376 is installed in the threaded hole 3562, and the adjusting rod 376 is rotated so that the adjusting rod 376 abuts the protrusion 3732, pushing the mounting seat 35 relative to the adjusting rotation axis L The rotating member 373 and the base 375 rotate to adjust the horizontal angle of the mounting seat 35 and the connecting portion 36, and the first elastic member 372 is stretched. Rotate the adjusting rod 376 in the opposite rotation direction, the mounting seat 35 is pulled by the first elastic member 372 around the adjusting rotation axis L to rotate and reset relative to the rotating member 373 and the base 375.

It can be understood that, in some other embodiments, the base 375 may be omitted, and the rotating member 373 and the bearing seat 374 may be directly fixedly mounted on the top surface of the movable pole 24.

It can be understood that the aforementioned adjustment mechanism 37 can be selectively used. When the adjustment mechanism 37 is cancelled, the mounting shell 356 of the mounting seat 35 can be eliminated, and the holding member 352 is mounted on the top surface of the movable pole 24 or other additional mounting surfaces. It should be understood that the holding member 352 may also extend to form a bottom surface and surround the lower surface of the connecting portion 36 of the beam assembly 30, that is, the holding member 352 may have a bottom surface which is mounted on the mounting shell 356.

It is understandable that other fixing mechanisms can also be used to simultaneously press the connecting portion 36 on the bottom surface and one side surface of the mounting seat 35. For example, in some embodiments, a cam handle 354a as shown in FIG. 20 can be used. The cam handle 354a is mounted on the holder 352, and the cam handle 354a can be rotated relative to the holder 352 to make the cam handle 354a abut The fixing surface 3624 allows the cam handle 354a to press the connecting portion 36 on the bottom surface and one side surface of the mounting seat 35, or to disengage the cam handle 354a from the fixing surface 3624, so that the connecting portion 36 can be removed from the mounting seat 35.

Please refer to FIG. 21. The cam handle 354a includes a cam portion 3542a and a handle 3544a. The handle 3544a is connected to one end of the cam portion 3542a. The cam portion 3542a is provided with a shaft hole 3540a, a rotating shaft is used to pass through the shaft hole 3540a, and both ends of the rotating shaft are fixed to the holding member 352, so that the cam handle 354 can rotate around the rotating shaft. The cam portion 3542a is a disc cam, which is a disc-shaped member that rotates around a rotation axis and has a variable diameter. It can rotate around the rotation axis in the first rotation direction to abut against the fixed surface 3624, or it can rotate along the second rotation direction. The rotation shaft rotates to deviate from the fixed surface 3624, and the first rotation direction is opposite to the second rotation direction.

In one embodiment, the cam handle 354 presses the beam on the mounting seat from a direction at a predetermined angle to the horizontal. The angle can be predetermined. According to the distance between the rotation axis of the cam portion 3542a and the connecting portion 36 and the shape design of the cam portion 3542a, the predetermined pressing angle can be calculated. Preferably, the contact surface of the cam portion 3542a and the connecting portion 36 is also arranged at a certain angle to the horizontal direction, and the angle of the contact surface is adapted to the aforementioned pressing angle, which can improve the pressing effect. Since the compaction does not require a very precise angle, "fitting" only requires that both of them are at an obvious angle to the horizontal. For example, the pressing angle may be 30 degrees, 45 degrees or 60 degrees, and the angle of the contact surface may also be a similar angle.

It can be understood that the cam handle 354a is not limited to directly pressing the beam on the mounting seat 35, and the cam handle 354a can also cooperate with other movable members to press the beam on the mounting seat 35.

Please refer to FIGS. 22-25 together. In one embodiment, the fixing mechanism further includes a limit rod 356a and a compression spring 358a. The limiting rod 355 is installed on the holding member 352, and the limiting rod 356a is movable relative to the holding member 352, the moving direction of the limiting rod 356a is substantially perpendicular to the horizontal direction, and the limiting rod 356a One end of the rod 356a abuts on the cam portion 3542a. When the cam handle 354a rotates relative to the holding member 352, the limiting rod 356a is driven to move relative to the holding member 352, as shown in FIG. 24, so that the other end of the limiting rod 356a moves from The direction of the first angle presses the cross beam on the bottom surface and one side surface of the mounting seat 35, as shown in FIG. 25 or so that the other end of the limit rod 356a is separated from the cross beam, so that the The beam can be removed from the mounting seat 35.

The holding member 352 is provided with a sliding groove 353a, the length of the sliding groove 353a is substantially perpendicular to the horizontal direction, and the limiting rod 356a penetrates the sliding groove 353a. The sliding groove 353a includes a communicating square groove 3530a and a circular groove 3532a. The end of the limit rod 356a abutting the cam portion 3542a is closer to the circular groove 3532a, and the limit rod 356a is used for The other end of the beam is pressed closer to the square groove 3530a. The inner wall of the sliding groove 353a is provided with an annular stop 3534a, and the annular stop 3534a is located between the square groove 3530a and the circular groove 3532a. At the junction, the limiting rod 356a is sleeved on the annular stop 3532a.

One end of the limiting rod 356a is provided with a limiting portion 3560a, and the other end of the limiting rod 356a is provided with a pressing portion 3562a. One end of the limiting rod 356a abuts against the cam portion 3542a through the limiting portion 356a. The cross-sectional size of the limiting portion 356a is larger than the cross-sectional size of the circular groove 3532a. When the rod 356a moves, the limiting portion 356a can abut against the opening of the sliding groove 353a of the holding portion 352, so that the limiting rod 356a cannot continue to move.

The cross section of the pressing portion 3562a is rectangular, and the pressing portion 3562a fits the square groove 3530a, which limits the rotational freedom of the limit rod 356a, so that the limit rod 356 is only It can move relative to the holding portion 352. The pressing portion 3562a has a pressing inclined surface 3563a and a pressing flat surface 3564a. The pressing inclined surface is perpendicular to the direction of the first angle, that is, the pressing inclined surface 3563a is inclined with respect to the bottom surface of the mounting seat 35, and the other end of the limit rod 356a passes through the pressing inclined surface 3563a. The beam is pressed tightly on the mounting seat 35.

The pressing plane 3564a is along the horizontal direction, that is, the pressing plane 3564a is parallel to the bottom surface of the mounting seat 35, and the other end of the limit rod 356a passes through the pressing inclined surface 3563a and the pressing The flat surface 3564a is pressed together on the mounting seat 35, which improves the abutment between the other end of the limit rod 356a and the cross beam more stably.

The compression spring 358a is used to keep one end of the limiting rod 356a in contact with the cam portion 3542a. The compression spring 358a is sleeved on the limit rod 356a, the compression spring 358a is received in the circular groove 3532a, and the compression spring 358a abuts against the annular stop 3534a and the limit rod. Between 3560a.

It is understandable that the compression spring 358a can be replaced with other elastic structures. For example, a pneumatic cylinder is provided in the limit rod 356a, so that the limit rod 356a itself can be elastically stretched, as long as one end of the limit rod 356a can be It is sufficient to keep in contact with the cam portion 3542a.

It can be understood that, in addition to the above-mentioned implementation, the fixing mechanism can also press the beam on the mounting seat from a direction at a preset angle to the horizontal in other ways. For example, the fixing mechanism itself can be used to apply a vertical downward force, but is arranged at The stress surface on the beam or fixedly connected to the beam (corresponding to the "contact surface" in the above embodiment) is at a certain angle to the horizontal, and the fixing mechanism can also press the beam from a direction at a preset angle to the horizontal Tightly on the mounting seat.

Please refer to FIG. 22 and FIG. 23 together. In some embodiments, the adjusting mechanism 37a includes an adjusting worm 370a and an adjusting worm gear 372a.

The joint mechanism 39 includes a first fixing member 391, a second fixing member 396, a first rotating shaft 397, a locking member 392, a second rotating shaft 393, a second elastic member 394 and a locking mechanism 395.

The first fixing member 391 and the second fixing member 396 are hingedly connected together by a first rotating shaft 397. The first fixing member 391 is approximately a cube, one end of which is hinged to one end of the second fixing member 396. The first fixing member 391 defines a first through hole 3910.

The locking member 392 is received in the first through hole 3910, the second rotating shaft 393 passes through the middle of the locking member 392, and both ends of the second rotating shaft 393 are respectively mounted on the first fixing Pieces 391 of the side wall. The buckle 392 can rotate around the second shaft 393, one end of the buckle 392 has a hook 3922, and one end of the second elastic member 394 abuts the other end of the buckle 392 , The other end of the second elastic member 394 abuts the inner wall of the first fixing member 391. The second elastic member 394 is a compression spring for restoring elastic deformation to push the locking member 392 to rotate around the second rotating shaft 393.

The locking mechanism 395 is a screw, which includes a knob and at least a section of screw. One end of the locking mechanism 395 passes through the first fixing member 391 from the outside of the first fixing member 391 to resist the buckle 392. The locking mechanism 395 and the second elastic member 394 are located on the same side of the central axis of the second rotating shaft 393, and the hook portion 3922 is located on the other side of the central axis of the second rotating shaft 393.

The second fixing member 396 is also roughly a cube, and a second through hole 3960 is opened. The inner wall of the second through hole 3960 is provided with a protrusion 3962. The first fixing member 391 is fixed inside the connecting portion 36, and the second fixing member 396 is fixed inside the left cross beam portion 32 or the right cross beam portion 34, so that the left cross beam portion 32 or the right cross beam portion 34 can be engaged with the connecting portion 36.

When the first fixing member 391 and the second fixing member 396 are closed, the first fixing member 391 is in contact with the second fixing member 396, and the first through hole 3910 communicates with the second through hole 3960. Pushed by the second elastic member 394, the hook portion 3922 is buckled on the locking protrusion 3962, and the locking mechanism 395 is rotated so that the locking mechanism 395 presses the locking member 392, so that the The hook portion 3922 is further locked to the locking protrusion 3962, so that the left cross beam portion 32 or the right cross beam portion 34 is stably deployed relative to the connecting portion 36.

Rotate the locking mechanism 395 to disengage the locking member 392, so that the first fixing member 391 rotates relative to the second fixing member 396, and the hook 3922 is separated from the locking protrusion 3962. The first fixing member 391 is separated from the second fixing member 396 so that the left cross beam portion 32 or the right cross beam portion 34 can be rotated relative to the connecting portion 36 to fold the cross beam assembly 30.

In this embodiment, with the push of the second elastic member 394, the hook portion 3922 can be conveniently buckled on the hook 3962, so that the hook portion 3922 and the hook 3962 are pre-buckled, and then The locking mechanism 395 presses the locking member 392 so that the hook portion 3922 is further locked to the locking protrusion 3962.

It is understandable that the locking mechanism 395 can press against other parts of the buckle 392, so that the hook portion 3922 is further locked to the protrusion 3962, as long as the lever with the second shaft 393 as the fulcrum loses rotation The possibility can be. For example, referring to FIG. 26, the locking mechanism 395 can press the hook 3922 from the lower part of the hook 3922. At this time, the hook 3922 can be appropriately lengthened so that the lower part of the second fixing member 396 can be provided with The locking mechanism 395 of the hook part 3922.

It can be understood that, in some other embodiments, the positions of the first fixing member 391 and the second fixing member 396 can be interchanged, that is, the first fixing member 391 is fixed to the left beam portion 32 or the right Inside the beam part 34, the second fixing member 396 is fixed inside the connecting part 36.

It can be understood that the first fixing member 391 and the second fixing member 396 may also be integrally formed with the inner wall of the left cross beam portion 32, the right cross beam portion 34 or the connecting portion 36, that is, the first fixing member 391 and the The second fixing member 396 may be a part of the inner wall of the left cross beam portion 32, the right cross beam portion 34 or the connecting portion 36. The first fixing member 391 and the second fixing member 396, the first fixing member 391 and the second fixing member 396 may not be connected together by a first shaft, and the two are not connected, but left The outer wall of the cross beam portion 32 or the right cross beam portion 34 and the connecting portion 36 are connected together by an additional rotating shaft, which can also realize a pivotable connection between the left cross beam portion 32 or the right cross beam portion 34 and the connecting portion 36.

It can be understood that the relative position between the second elastic member 394 and the locking mechanism 395 and the second rotating shaft 393 can be changed, that is, the second elastic member 394 can be closer to the second rotating shaft 393 than the locking mechanism 395, as long as the The locking member 392 can lock the locking protrusion 3962.

Please refer to FIGS. 27 and 28 together, which shows a second embodiment of the structure of the joint mechanism 39a. The joint mechanism 39a provided by this second embodiment is basically the same as the joint mechanism 39 in the above embodiment, except that one end of the buckle 392a is provided with a hook 3922a and a protrusion 3924a, and the two hooks 3922a are located at the same place. On opposite sides of the protrusion 3924a, the inner wall of the second through hole 3960 is provided with a latch 3962a, the number of the latch 3962a is two, and the position of each latch 3962a corresponds to a corresponding one of the hook The position of the part 3922a corresponds. The knob 395 is replaced with a button 395a, and the button 395a is mounted on the second fixing member 396. The second elastic member 394 is a compression spring compressed between the first fixing member 391 and the locking member 392a.

When the first fixing member 391 and the second fixing member 396 are closed, the first fixing member 391 is in contact with the second fixing member 396, the first through hole 3910 is in communication with the second through hole 3960, and the The second elastic member 394 is pressed against the locking member 392a, so that the two hook portions 3922a are respectively fastened to the two locking protrusions 3962a, and the first fixing member 391 and the second fixing member 396 are fastened to each other , So that the left cross-beam portion 32 or the right cross-beam portion 34 is expanded relative to the connecting portion 36.

When the button 395a is pressed, the button 395a pushes the protrusion 3924a to push the buckle 392a to rotate around the second shaft 393, the hook portion 3922a separates from the protrusion 3962a, so The second elastic member 394 is further compressed. At this time, the first fixing member 391 can rotate relative to the second fixing member 396, so that the first fixing member 391 is separated from the second fixing member 396, so that the The left cross beam portion 32 or the right cross beam portion 34 can rotate relative to the connecting portion 36 to fold the cross beam assembly 30. Lift the button 395a to move the button 395a away from the buckle 392a, and the second elastic member 394 resumes elastic deformation and pushes the buckle 392a to rotate around the second shaft 393, so that the The hook portion 3922a is fastened to the hook 3962a.

It can be understood that when the fasteners, protrusions and other parts in Figures 24-28 are made of hard materials with a little elasticity, no springs are needed to provide elastic restoring force, and the structural design can be adjusted in a similar manner as shown in Figure 24 The joint structure shown in -28: use the slight deformation of the fastener and the protrusion to realize the engagement between the first fixing part and the second fixing part, and then use the rigidity of the material of the fastener and the protrusion to realize the card The lock will not loosen, and the buckle and the buckle will be deformed under the action of a large external force to realize the loosening between the first fixing part and the second fixing part. In addition, structures such as screwing mechanisms and buttons can be similarly designed.

Please refer to FIG. 29, in order to increase the engagement strength of the left cross beam portion 32 and the right cross beam portion 34 with the connecting portion 36 respectively, so that the left cross beam portion 32 and the right cross beam portion 34 can be mounted with a larger weight calibration element A locking mechanism 50 may be provided on the beam of the calibration bracket 100, for example, a buckle structure 50. One buckle structure 50 is connected between the left beam portion 32 and the connecting portion 36, and the other buckle The structure 50 is connected between the right cross beam portion 34 and the connecting portion 36.

Each of the buckle structures 50 includes a first buckle 52 and a second buckle 54. The connecting portion 36 is provided with a first fastener 52, one end of the first fastener 52 is hinged to the connecting portion 36, and the first fastener 52 is hinged to one end of the connecting portion 36 A flip part 522 is provided, the other end of the first fastener 52 is provided with a hook rod 524, a second fastener 54 is provided on the left beam part 32 or the right beam part 34, and the second fastener The fastener 54 is provided with a buckle portion 544. The hinge joint of the left cross beam portion 32 or the right cross beam portion 34 and the connecting portion 36 is located on one side of the connecting portion 36, and the first fastener 52 and the second fastener 54 are located on the connecting portion 36 on the other side. When the left cross beam portion 32 and the right cross beam portion 34 are expanded relative to the connecting portion 36, the left cross beam portion 32 and the right cross beam portion 34 respectively contact the connecting portion 36, and the hook rod 524 is fastened to The buckle portion 544. Pulling the pulling portion 522, the hook rod 524 is separated from the buckle portion 544, the first buckle member 52 and the second buckle member 54 can be separated, so that the left beam portion 32 or the right The beam portion 34 can be folded relative to the connecting portion 36.

It can be understood that, in some other embodiments, the positions of the first fastener 52 and the second fastener 54 can be interchanged, that is, the first fastener 52 is disposed on the left beam portion 32 or the right cross beam portion 34, the second fastener 54 is disposed on the connecting portion 36. In some embodiments, the first buckle 52 and the second buckle 54 can be used in conjunction with the joint mechanism 39, that is, there are joint mechanisms in the inner wall of the left beam portion 32, the right beam portion 34, and the connecting portion 36 at this time. 39. In some embodiments, the first buckle 52 and the second buckle 54 can also be used separately, that is, there is no joint mechanism 39 in the inner wall of the left beam portion 32, the right beam portion 34, and the connecting portion 36 at this time. In addition, hinges are added at the positions where connection between the left cross beam portion 32, the right cross beam portion 34 and the connecting portion 36 needs to be connected.

It can be understood that the advantage of using a locking mechanism such as the buckle 50 and the joint mechanism 39 at the same time is that the buckle 50 can provide temporary fastening between the beam components. Since the beam of the calibration bracket 100 is generally relatively long, the left and

right beam portions

32 and 34 are usually designed to be relatively long, so they are relatively heavy. If it is necessary to lift the left cross-beam portion 32 or the right cross-beam portion 34 while operating the locking mechanism 50 between it and the connecting portion 36, it is very inconvenient for an operator. The presence of the buckle 50 solves this problem, so that the operator does not need to lift the left beam portion 32 or the right beam portion 34, and then lock the components of the beam by operating the locking mechanism, so that both ends of the beam can carry a heavier load. Calibration components.

It can be understood that, in order to achieve temporary engagement, the embodiments provided in this specification are not the only implementation manner. For example, when the buckle or the buckle in the joint mechanism is made of a hard material with a certain elasticity, the spring, rotating shaft and other structures described in the embodiment are not needed, and temporary buckling can also be achieved. At this time, you can also use the knob to push the fastener and the protrusion to prevent it from falling off, or you can use the button to realize the quick separation between the fastener and the protrusion.

It is understood that other locking mechanisms can also be used. For example, as shown in Fig. 30 and Fig. 31, the locking mechanism 395b includes a mounting support 3950b, a locking cam handle 3952b, a top post 3954b and a third elastic member 3956b. The mounting support 3950b is mounted on the first fixing member 391, the locking cam handle 3952b is mounted on the mounting support 3950b, and the locking cam handle 3952b can rotate relative to the mounting support 3950b to drive the top column 3954b The fastening member 392 is pressed tightly, so that the first fixing member 391 and the second fixing member 396 are fastened. The locking cam handle 3952b has the same structure as the cam handle 354a shown in FIG. 20 and FIG. 21, and the structure of the locking cam handle 3952b will not be repeated here. The top post 3954b passes through the first fixing member 391, one end of which is used to abut against the locking cam handle 3952b, and the other end is used to abut against the buckle 392b. The third elastic member 3956b is a compression spring, which is sleeved on the top column 3954b. One end of the third elastic member 3956b is fixed to the top column 3954b, and the other end abuts against the fastener 392.

Rotate the locking cam handle 3952b to push the top post 3954b to abut the buckle 392, so that the first fixing member 391 and the second fixing member 396 are fastened, and the third elastic member 3956b is compressed. When the locking cam handle 3952b is turned in the opposite direction, the third elastic member 3956b pushes the top post 3954b to move upward to disengage the buckle member 392, and the first fixing member 391 and the second fixing member 396 can be separated.

It can be understood that, in some embodiments, the locking mechanism 395 in FIGS. 24, 25, and 26, and the button 395a in FIGS. 27 and 28 can all be replaced with a locking mechanism 395b.

In this embodiment, the cross beam assembly 30 is installed on the top surface of the movable vertical rod 24, which makes the center of gravity of the cross beam assembly 30 closer to the center of gravity of the stand assembly 20 than the traditional calibration frame, which can increase the calibration The shelf is stable, and the base body 12 with a smaller area can be used. It is understandable that, in some other embodiments, the beam assembly 30 can be installed at different positions of the stand assembly 20 according to different requirements, so that the beam assembly 30 is located at a suitable height, which can be used for mounting lighter weight calibrations. Components, for example, radar absorption/reflection plates, mirrors, etc.

Please refer to FIGS. 32 and 33 together. Another embodiment of the present invention also provides a calibration system 600, which includes a calibration element and the calibration bracket 100 provided in the above-mentioned embodiment, and the calibration element can be mounted on the calibration bracket 100 For example, the calibration element is a reflector 300 and a distance measuring device 400 (see FIG. 32). The reflector 300 can be mounted on the first rail 322 or the second rail 342 by a slider or a fixed block. The block or fixed block is installed on the first guide rail 322 or the second guide rail 342, and can slide along the first guide rail 322 or the second guide rail 342 together with the reflector 300, and the distance measuring device 400 is fixedly installed on the述横梁 Assembly 30. The reflector 300 may also be a target 300, and the two targets are mounted on the first guide rail 322 and the second guide rail 342 through a sliding block or a fixed block. The reflector or target 300 can also be directly mounted on the beam assembly 30 by means of hooks or the like. In this case, the first guide rail 322 and the second guide rail 342 can be eliminated.

The above-mentioned distance measuring device 400 is used to measure the height of the beam assembly 30 from the ground, and is preferably displayed on the liquid crystal screen of the distance measuring device 400. In one embodiment, the distance measuring device 400 is a laser rangefinder. The base 10 is provided with a through hole 120 for allowing the laser of the laser rangefinder 400 to hit the ground, so as to measure the height of the beam assembly 30 from the ground.

Since the distance measuring device 400 itself has a certain size, the vertical distance between the emission surface of the measuring beam and the center point of the calibration element can be compensated by adjusting parameters in the measurement software inside the distance measuring device 400.

For another example, the calibration element is a pattern plate 500 (see FIG. 33), and the first supporting member 312 and the second supporting member 332 jointly lift the pattern plate 500 to prevent falling. In addition, a first fixing block 510 may be installed on the first guide rail 322, the first fixing block 510 can slide along the first guide rail 322, and a second fixing block 520 is installed on the second guide rail 342. The second fixing block 520 can slide along the second guide rail 342, the first fixing block 510 and the second fixing block 520 are respectively located on opposite sides of the pattern plate 500, and the first fixing block 510 The pattern plate 500 is clamped in cooperation with the second fixing block 520.

In an optional embodiment, the first fixing block 510 and the second fixing block 520 are sliders on which the mirror 300 is installed. A slot is opened on the opposite side of the slider to clamp the pattern plate 500 to form a fixed block. For a specific description of this solution, refer to the embodiments shown in Figure 34, Figure 35 and Figure 36 for details. It can be understood that the first fixing block 510 and the second fixing block 520 may also be magnetic blocks, which attract the pattern plate 500 from behind by magnetic adsorption, so as to enhance the firmness of the pattern plate 500 on the beam assembly 30.

Please refer to Figure 34, Figure 35 and Figure 36 together. Since there is no vertical rod part above the mounting seat 35 in the folding bracket 100, it is impossible to use the upper end of the vertical rod to firmly install large calibration elements, such as a large pattern board for calibrating a front windshield camera, like a normal calibration bracket. Therefore, it is necessary to design a folding support structure that is also strong enough to install large-scale calibration elements.

In one embodiment, the cross beam assembly 30 includes a cross beam and at least one supporting rod, and the cross beam is connected to the at least one supporting rod. The cross beam supports the first fixed block 510 and the second fixed block 520, the first fixed block 510 and the second fixed block 520 can move along the cross beam, each of the fixed

blocks

510, 520 is used for Install a small calibration element, the first fixed block 510 and the second fixed block 520 and the at least one support rod can cooperate to support a large calibration element, and the first fixed block 510 and the second fixed block 520 from The large-scale calibration element is fixed at the left and right ends, and the at least one supporting rod supports the large-scale calibration element from below the large-scale calibration element.

Specifically, the mounting surface of the first fixing block 510 is provided with first positioning protrusions 512, and two of the first positioning protrusions 512 are provided along the length direction of the beam. The two first positioning protrusions 512 are used for accurate positioning of the target when the target is installed. Optionally, the first fixing block 510 is coated with a magnetic material or installed with a magnetic element, or is a magnetic block itself, so as to realize the adsorption installation of the target. Optionally, the first fixing block 510 is provided with a first holding mechanism 514, and the first holding mechanism 514 may be a positioning structure such as a card slot or a protrusion.

Similarly, the mounting surface of the second fixing block 520 is provided with second positioning protrusions 522, and the two second positioning protrusions 522 are provided along the length direction of the beam. The two second positioning protrusions 522 are used for accurate positioning of the target when the target is installed. Optionally, the second fixed block 520 is coated with a magnetic material or installed with a magnetic element, or is a magnetic block itself, so as to realize the adsorption installation of the small target. Optionally, the second fixing block 520 is provided with a second holding mechanism 524, and the second holding mechanism 524 may be a positioning structure such as a card slot or a protrusion. The first holding mechanism 514 and the second holding mechanism 524 are arranged opposite to each other.

In this embodiment, the first positioning mechanism 3120, the second positioning mechanism 3320, the first holding mechanism 514, and the second holding mechanism 524 are card slots and are located on the same plane to cooperatively support a large calibration element. It can be understood that, in some other embodiments, one or more of the first positioning mechanism 3120, the second positioning mechanism 3320, the first holding mechanism 514, and the second holding mechanism 524 may also be bumps and large The calibration element can be provided with grooves that cooperate with the bumps, so that the first positioning mechanism 3120, the second positioning mechanism 3320, the first holding mechanism 514, and the second holding mechanism 524 can cooperatively support the large calibration element.

The mounting base 35 includes a backing plate 357, the bottom end of the backing plate 357 is connected to the mounting surface of the mounting base 35 through hinges, hinges, etc., and the backing plate 357 can rotate up and down relative to the mounting base 35. The backing plate 357 includes a mounting surface and an inner surface that are opposed to each other. The mounting surface of the backing plate 357 is provided with third positioning protrusions 3572, and two third positioning protrusions 3572 are provided along the length direction of the beam.

The mounting surface of the mounting seat 35 is provided with a receiving groove 358, and the shape of the receiving groove 358 matches the shape of the backing plate 357 so that the backing plate 357 can be clamped in the receiving groove 358.

The backing plate 357 can rotate between a first position and a second position.

In the first position, the backing plate 357 is clamped in the receiving groove 358, the mounting surface of the backing plate 357, the mounting surface of the mounting seat 35, the mounting surface of the first fixing block 510, and the second fixing block 520 The mounting surface faces the same direction. The mounting surface of the backing plate 357 protrudes from the mounting surface of the mounting seat 35, and the mounting surface of the backing plate 357, the mounting surface of the first fixing block 510, and the mounting surface of the second fixing block 520 are located at the same Plane (see Figure 35). When calibrating the on-board component, the backing plate 357, the first fixing block 510 and the second fixing block 520 can be used to mount a calibration component. At this time, their respective mounting surfaces are on the same plane, which means that the calibration elements (assuming that they are designed to have the same thickness) mounted on them are on the same plane for calibration. Preferably, a positioning structure is provided on the mounting surface of the backing plate 357, the mounting surface of the first fixing block 510, and the mounting surface of the second fixing block 520 for accurately mounting the calibration element on each mounting surface For example, the first positioning protrusion 3572, the second positioning protrusion 512, and the third positioning protrusion 522 are located at the predetermined positions. At this time, the backing plate 357, the first fixing block 510, and the second fixing block 520 can be used individually to mount small-weight calibration elements, such as reflectors, small pattern plates, etc. (see FIG. 29). Optionally, the back or side surface of the calibration element may be provided with a positioning structure adapted to the positioning structure on the mounting surface, such as a positioning hole (not shown in the figure), a first positioning protrusion 3572, a second positioning The protrusion 512 or the third positioning protrusion 522 can be inserted into the positioning hole to achieve positioning. Optionally, the first positioning protrusion 3572, the second positioning protrusion 512, or the third positioning protrusion 522 may have magnetism to enhance the attraction force to the calibration element.

In the second position, the backing plate 357 rotates to be located below the mounting base 35, and the inner surface of the backing plate 357 and the mounting surface of the mounting base face the same direction and are flush. At this time, the calibration bracket 100 can be used to mount large-scale calibration elements with a relatively large weight, such as a large target board (usually a large pattern board). The bottom side of the large pattern board is supported by the first slot 3120 and the second slot 3320, and the left and right sides of the large pattern board are respectively locked in the third slot 514 and the fourth slot 524 (see FIG. 36). Since the first fixing block 510 and the second fixing block 520 have a certain thickness, if the first slot 514 and the second slot 524 on the side are used to install the target, the target must be installed on the first fixing block 510. , The loading surface of the second fixing block 520 is on a plane slightly behind. The switch of the backing plate 357 between the first position and the second position is to adjust the distance difference between the target installation planes in the two installation methods.
