The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Furthermore, the technical features mentioned in the different embodiments of the invention described below can be combined with each other as long as they do not conflict with each other.

Referring to fig. 1 and fig. 2, an embodiment of the present invention provides a calibration support 100, which includes a base 10, an upright assembly 20 and a beam assembly 30, wherein the upright assembly 20 is fixedly connected to the base 10, the beam assembly 30 includes a first beam portion 32, a second beam portion 34 and a connecting portion 36, the connecting portion 36 is mounted on the upright assembly 20, one end of the connecting portion 36 is hinged to the first beam portion 32, and the other end of the connecting portion 36 is hinged to the second beam portion 34.

The beam assembly 30 includes at least one articulation mechanism 38, the articulation mechanism 38 being connected between the first beam portion 32 and the connecting portion 36 or between the second beam portion 34 and the connecting portion 36.

The joint mechanism 38 includes a first fixing member 381, a second fixing member 382, and a rotation connection block 383 connected between the first fixing member 381 and the second fixing member 382. One end of the rotation connecting block 383 is rotatably fixed to the first fixing member 381, and one end of the second fixing member 382 is rotatably fixed to the other end of the rotation connecting block 383, so that the first beam portion 32 or the second beam portion 34 can rotate and fold with respect to the connecting portion 36; the first beam portion 32 and the second beam portion 34 rotate in the same direction. The first beam portion 32 and the second beam portion 34 can each be rotated toward each other relative to the connecting portion 36 to fold the beam assembly 30, and the first beam portion 32 and the second beam portion 34 can also each be rotated away from each other relative to the connecting portion 36 to unfold the beam assembly 30.

The installation comprises fixed installation such as welding installation and the like, and also comprises detachable installation.

The beam assembly 30 may be used to mount calibration elements, such as a multi-line laser 200, calibration targets, radar reflecting or absorbing devices, etc., to calibrate the vehicle-mounted assisted steering system.

The first beam portion 32, the second beam portion 34, and the connecting portion 36 constitute a cross beam.

In this embodiment, the first beam portion 32 and the second beam portion 34 can rotate oppositely relative to the opposite sides of the connecting portion 36, that is, the first beam portion 32 and the second beam portion 34 rotate in the same direction, either clockwise or counterclockwise. In this case, the first beam portion 32 and the second beam portion 34 are located on opposite sides of the connecting portion 36 in the folded state. For example, they may be folded up and down, or folded forward and back, with the folded first and second beam portions 32 and 34 lying against the connecting portion 36 and secured to the connecting portion 36 by releasable securing means, thereby reducing the bulk of the calibration stand 100 for ease of shipping. The length of the connecting portion 36 may be relatively short when the first and second beam portions 32, 34 are folded one up and one down, or one folded forward and one folded back. Similarly, to further reduce the space occupied by the calibration support 100, the cross member assembly 30 may be removed from the stand assembly 20, carried to a desired location, and then mounted on the stand assembly 20.

Alternatively, the first beam portion 32 and the second beam portion 34 may also rotate opposite to each other with respect to the same side of the connecting portion 36, that is, the first beam portion 32 and the second beam portion 34 rotate in opposite directions, and if one of the two pivots clockwise, the other pivots counterclockwise. In this case, the first and second beam portions 32, 34 are located on the same side of the connecting portion 36 in the folded state. For example, they may be folded together downward, or they may be folded together upward, forward, and rearward. Alternatively, when the first beam portion 32 and the second beam portion 34 are folded downward, the length of the connecting portion 36 may be relatively short, and the first beam portion 32 and the second beam portion 34 are in a sagging state, so that the beam assembly 30 may not need to be taken off from the stand assembly 20, the occupied space of the calibration support 100 may be significantly reduced, and the calibration support may be conveniently carried by a vehicle. When the first and second beam portions 32, 34 are folded upwardly, forwardly and rearwardly, means may be provided to rotate the beams so that the final folding direction of the first and second beam portions 32, 34 is downwardly, or both may be in a sagging condition; or the connecting portion 36 may be relatively long, and the folded first and second beam portions 32 and 34 may be placed against the connecting portion 36 and secured to the connecting portion 36 by releasable securing means. In the latter case, to further reduce the space occupied by the calibration support 100, the cross member assembly 30 may be removed from the stand assembly 20, carried to a desired location, and then mounted on the stand assembly 20.

It will be appreciated by those skilled in the art that the manner in which the beam assembly 30 is folded is not limited to that described above. For example, the beam may be folded to two ends, where there are no connections 36; the cross beam can also be folded into four or more sections. But preferably three sections, since this leaves the beam mid-section unbroken, it is possible to use only one fastening member at the mid-section and to fix the beam stably and evenly to the uprights.

Referring to fig. 3, the number of the joint mechanisms 38 provided in this embodiment is two, one of the joint mechanisms 38 is slidably connected between the first beam portion 32 and the connecting portion 36, and the other joint mechanism 38 is slidably connected between the second beam portion 34 and the connecting portion 36.

In this embodiment, the rotating connection block 383 is Z-shaped, the height of the rotating connection block 383 is less than or equal to the height of the first fixing block 381, and the height of the rotating connection block 383 is less than or equal to the height of the second fixing block 382.

The rotary connecting block 383 is arranged in a Z shape, so that the rotation angle of the first beam portion 32 or the second beam portion 34 is increased, the rotation angle range of the first beam portion 32 or the second beam portion 34 around the connecting portion 36 is 0-360 degrees, and the first beam portion 32 or the second beam portion 34 rotates smoothly around the connecting portion 36.

The length of the first pin 384 is less than or equal to the height of the first fixed block 381, and the length of the second pin 385 is less than or equal to the height of the second fixed block 382.

Preferably, after the first pin 384 is installed, the top end and the bottom end of the first pin 384 do not exceed the top surface and the bottom surface of the first fixing block 381; after the second pin 385 is mounted, the top end and the bottom end of the second pin 385 do not exceed the top surface and the bottom surface of the second fixing block 382.

The top and bottom surfaces of the first fixing block 381 are surfaces corresponding to the first fixing block 381 with respect to the mounting direction of the first pin shaft 384.

It is understood that the rotary connection block 383 may also be "i" shaped, and the first protrusion 3811 and the second protrusion 3821 are respectively located in two openings of the rotary connection block 383.

When the first beam portion 32 and the connecting portion 36 are respectively provided with a receiving cavity for receiving the joint mechanism 38, two receiving cavities are respectively provided with a limiting device for limiting the stroke of the joint mechanism 38, the joint mechanism 38 is slidably connected between the first beam portion 32 and the connecting portion 36, and the sum of the length of the receiving cavity of the connecting portion 36 and the length of the receiving cavity of the first beam portion 32 needs to be greater than or equal to the length of the joint mechanism 38 which is completely unfolded, so that the joint mechanism 38 can be completely received in the receiving cavity of the first beam portion 32 and the receiving cavity of the connecting portion 36.

Similarly, when the second beam portion 34 and the connecting portion 36 are respectively provided with a receiving cavity for receiving the joint mechanism 38, two receiving cavities are respectively provided with a limiting device for limiting the stroke of the joint mechanism 38, the joint mechanism 38 is slidably connected between the second beam portion 34 and the connecting portion 36, and the sum of the length of the receiving cavity of the connecting portion 36 and the length of the receiving cavity of the second beam portion 34 is greater than or equal to the length of the joint mechanism 38 which is completely unfolded, so that the joint mechanism 38 can be completely received in the receiving cavity of the second beam portion 34 and the receiving cavity of the connecting portion 36.

The fully deployed length of the joint mechanism 38 refers to the entire length of the joint mechanism 38 in the displayed state when the first mount 381 and the second mount 382 are located on the same plane.

When only the connecting portion 36 is provided with a receiving cavity for receiving the joint mechanism 38, the second fixing member 382 is completely fixed to the inner wall of the first beam portion 32 or the second beam portion 34, or the second fixing member 382 is integrally formed with the inner wall of the first beam portion 32 or the second beam portion 34, the joint mechanism 38 is slidably received in the receiving cavity of the connecting portion 36, and the joint mechanism 38 can be completely received in the receiving cavity of the connecting portion 36.

Similarly, when only the first beam portion 32 or the second beam portion 34 is provided with a receiving cavity for receiving the joint mechanism 38, the first fixing member 381 is completely fixed on the inner wall of the connecting portion 36, or the first fixing member 381 and the inner wall of the connecting portion 36 are integrally formed, the joint mechanism 38 is slidably received in the receiving cavity of the first beam portion 32 or the receiving cavity of the second beam portion 34, and the joint mechanism 38 is fully received in the receiving cavity of the first beam portion 32 or the receiving cavity of the second beam portion 34.

Referring to fig. 5, when the first fixing member 381 and the second fixing member 382 are located on the same plane, the first beam portion 32 or the second beam portion 34 is pushed toward the connecting portion 36 by force, so that the joint mechanism 38 is completely accommodated between the connecting portion 36 and the first beam portion 32 or the second beam portion 34, and the connecting portion 36 abuts against the first beam portion 32 or the second beam portion 34, so that the first beam portion 32 or the second beam portion 34 is stably in the unfolded state relative to the connecting portion 36.

The first beam portion 32 or the second beam portion 34 is pulled in a direction away from the connecting portion 36, such that the first fixing member 381 is exposed at the connecting portion 36, the second fixing member 382 is exposed at the first beam portion 32 or the second beam portion 34, and the second fixing member 382 rotates relative to the first fixing member 381, such that the first beam portion 32 or the second beam portion 34 can rotate relative to the connecting portion 36, such that the beam assembly 30 is folded.

When the connecting portion 36 is short, please refer to fig. 6, the first beam portion 32 and the second beam portion 34 can be rotated oppositely relative to the opposite sides of the connecting portion 36, so that the first beam portion 32 and the second beam portion 34 are located at the opposite sides of the connecting portion 36, so that the beam assembly 30 is folded, and the folded beam assembly 30 is S-shaped.

When the connecting portion 36 is long, the first and second beam portions 32, 34 can be rotated toward each other relative to the same side of the connecting portion 36, such that the first and second beam portions 32, 34 are on the same side of the connecting portion 36, thereby folding the beam assembly 30; alternatively, the first and second beam portions 32, 34 can be rotated toward each other relative to opposite sides of the connecting portion 36 such that the first and second beam portions 32, 34 are on opposite sides of the connecting portion 36 to allow the beam assembly 30 to fold.

It is understood that the first fixing member 381 may not be housed inside the connecting portion 36, and the second fixing member 382 may not be housed inside the first beam portion 32 or the second beam portion 34, for example, the first fixing member 381 may be slidably sleeved on the outer wall of the connecting portion 36, the second fixing member 382 may be slidably sleeved on the outer wall of the first beam portion 32 or the outer wall of the second beam portion 34, and when the beam assembly 30 is unfolded or folded, the beam assembly 30 is further fixed by a locking member, so that the first beam portion 32 or the second beam portion 34 is stably unfolded or folded with respect to the connecting portion 36.

It will be appreciated that the first mount 381 and the second mount 382 may not be connected together by the rotary connecting block 383, but the first beam portion 32 or the second beam portion 34 and the outer wall of the connecting portion 36 are connected together by an additional rotating shaft, which also enables the pivotable connection between the first beam portion 32 or the second beam portion 34 and the connecting portion 36.

Referring to fig. 7, in order to increase the engaging force of the first beam portion 32 and the second beam portion 34 with the connecting portion 36, respectively, so that the first beam portion 32 and the second beam portion 34 can carry calibration elements with larger weight, the calibration support 100 may further include snap structures 40, one of the snap structures 40 is connected between the first beam portion 32 and the connecting portion 36, and the other of the snap structures 40 is connected between the second beam portion 34 and the connecting portion 36.

Each of the fastener structures 40 includes a first fastener member 42 and a second fastener member 44. The connecting portion 36 is provided with a first fastener 42, one end of the first fastener 42 is hinged to the connecting portion 36, the first fastener 42 is hinged to one end of the connecting portion 36 and is provided with a pulling portion 422, the other end of the first fastener 42 is provided with a hook pull rod 424, the first beam portion 32 or the second beam portion 34 is provided with a second fastener 44, and the second fastener 44 is provided with a fastener portion 444. The hinge of the first or second beam portion 32, 34 to the connecting portion 36 is located on one side of the connecting portion 36, and the first and second fastening members 42, 44 are located on the other side of the connecting portion 36. When the first and second beam portions 32 and 34 are unfolded with respect to the connecting portion 36, the first and second beam portions 32 and 34 are respectively in contact with the connecting portion 36, and the hook bar 424 is fastened to the buckle portion 444. By pulling the pulling portion 422, the hook lever 424 disengages from the snap portion 444, and the first and second snap members 42 and 44 can be separated, so that the first or second beam portion 32 or 34 can be folded with respect to the connecting portion 36.

It will be appreciated that in some other embodiments, the positions of the first and second fasteners 42, 44 may be interchanged, i.e., the first fastener 42 is disposed on the first or second beam portion 32, 34 and the second fastener 44 is disposed on the connecting portion 36. In some embodiments, the first and second fasteners 42, 44 may be used in conjunction with the articulation mechanism 38, i.e., when the articulation mechanism 38 is within the inner walls of the first and second beam portions 32, 34 and the connecting portion 36. In some embodiments, the first and second fasteners 42, 44 may also be used alone, i.e., without the articulating mechanism 38 within the inner walls of the first and second beam portions 32, 34 and the connecting portion 36.

Referring to fig. 8, in some embodiments, the stand assembly 20 may include a fixed upright 22 and a movable upright 24, the movable upright 24 is sleeved in the fixed upright 22, and the movable upright 24 is movable relative to the fixed upright 22 along the length direction of the fixed upright 22.

By using the manner of sleeving and connecting the movable vertical rod 24 and the fixed vertical rod 22, the height of the stand assembly 20 can be reduced to be approximately half of the original height, and the stand assembly 20 can be very suitable for being placed in a rear trunk of a vehicle such as an automobile and the like to be carried by matching with the folding of the beam assembly 30.

It will be appreciated that the fixed uprights can also be used as the inner uprights and the mobile uprights as the outer uprights, if desired.

Optionally, the fixed vertical rod 22 and the movable vertical rod 24 are square tubes, and the movable vertical rod 24 is tightly sleeved in the fixed vertical rod 22, so 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, and the movable vertical rod 24 can be prevented from moving in other directions relative to the fixed vertical rod 22. This configuration is important to achieving the collapsibility of the calibration stand 100 because it is generally necessary to utilize the fixed relative positional relationship between the various components of the calibration stand 100 during calibration, for example, it is possible to mount a laser on the outer surface of the fixed upright 22 that is used to locate the center axis of the vehicle to determine the relative position of the target carried on the beam assembly 30 with respect to the vehicle. Therefore, if the relative position of each component is changed slightly, the calibration precision is affected, or an additional fine adjustment mechanism is required to compensate. If the relative position of the components varies greatly, it may also lead to failure of the added additional fine adjustment mechanism. Thus, in a telescopic manner, relative movements between the mobile upright 24 and the fixed upright 22 other than along the length, such as relative rotations, are to be excluded. One convenient way is for the moving upright 24 to be square with the fixed upright 22, thus ensuring only longitudinal relative movement between the two.

It will be understood that in some other embodiments, the fixed upright 22 and the mobile upright 24 can also be tubes of other shapes, for example, tubes with a cross section of mutually matching polygons, so that the mobile upright 24 can only move relative to the fixed upright 22 along the length of the fixed upright 22, and so that the mobile upright 24 is prevented from moving in other directions relative to the fixed upright 22. Here, "mutually fit" does not necessarily require that the fixed upright 22 and the mobile upright 24 have the same cross-section, for example, the cross-section of the fixed upright 22 arranged outside may be hexagonal, and the cross-section of the mobile upright 24 arranged inside may be quadrangular bordering on the hexagonal, and the same effect may be achieved that the mobile upright 24 can only move relative to the fixed upright 22 in the length direction of the fixed upright 22. The fixed upright 22 and said mobile upright 24 can also have a cross section in the form of mutually cooperating oval cylindrical tubes, the oval cross section also limiting to a certain extent the relative rotation between them.

In some embodiments, a driving mechanism (not shown) may be mounted on the fixed upright 22 for driving the movable upright 24 to move relative to the fixed upright 22 along the length of the fixed upright 22. The driving mechanism may be a gear box transmission, a lead screw transmission, a synchronous belt transmission, etc., as long as it can drive the moving upright 24 to move relative to the fixed upright 22, such as the driving mechanism described in patent application No. CN 201911067124.0.

In some embodiments, the movable vertical rod 24 is provided with a limiting portion located in the fixed vertical rod 22, the inner wall of the fixed vertical rod 22 is provided with a flange close to the top end of the fixed vertical rod 22, and when the movable vertical rod 24 moves relative to the fixed vertical rod 22 until the limiting portion abuts against the flange, the movable vertical rod 24 stops moving, so that the movable vertical rod 24 is prevented from being separated from the fixed vertical rod 22.
