[0047] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0048] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0049] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0050] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0051] Intelligent driving systems can assist or completely replace drivers. Therefore, cars with intelligent driving systems generally have sensors such as radar and cameras, and the parameters of components such as sensors and wheels need to be calibrated and adjusted. Each component requires different calibration equipment, which results in a large number of devices required for calibration and high equipment costs.

[0052] To address the aforementioned technical issues, this application proposes an intelligent vehicle measurement device. The device includes a camera 50 and a mounting assembly 460 for attaching calibration components on a crossbeam assembly. The length of the column assembly 20 is variable, and the crossbeam assembly 40 has a large adjustment range, making it suitable for both four-wheel alignment testing and ADAS calibration.

[0053] The vehicle measuring equipment provided in the embodiments of this application will now be described.

[0054] Please refer to Figures 1 to 3. The vehicle measuring equipment includes a base assembly 10, a column assembly 20 mounted on the base assembly 10, a crossbeam assembly 40 mounted on the column assembly 20, a camera 50 fixed on the crossbeam assembly 40, and a mounting assembly 460 mounted on the crossbeam assembly 40 for mounting calibration components. The base assembly 10 includes a rotating mechanism 13 capable of outputting rotational motion. The column assembly 20 includes a first column 21 and a second column 22 slidably connected to the first column 21. The first column 21 is fixedly connected to the motion output end of the rotating mechanism 13, and the crossbeam assembly 40 is driven to rise and fall by the second column 22.

[0055] The base assembly 10 is generally placed on the ground to support the column assembly 20, facilitating the movement of the vehicle measuring equipment and making the vehicle measuring equipment more stable when placed. The base assembly 10 includes a rotating mechanism 13 capable of outputting rotational motion. The rotating mechanism 13 has a motion output end for rotational motion, and the motion output end of the rotating mechanism 13 is fixedly connected to the first column 21 of the column assembly 20.

[0056] The column assembly 20 is mounted on the base assembly 10. The column assembly 20 is generally a vertically arranged elongated structure used to support the crossbeam assembly 40, positioning it at a set height. The column assembly 20 includes a first column 21 and a second column 22. The second column 22 is slidably connected to the first column 21, and the crossbeam assembly 40 also moves up and down when the second column 22 is in motion. In this way, the vertical travel of the crossbeam assembly 40 can be increased without increasing the length of the column assembly 20 (its minimum length when retracted), enabling simultaneous four-wheel alignment and ADAS detection.

[0057] The height of the crossbeam assembly 40 is variable, allowing it to move up and down relative to the pillar assembly 20. During ADAS calibration or four-wheel alignment, the height of the crossbeam assembly 40 can be adjusted by raising and lowering it, thereby adjusting the height of the calibration components on the crossbeam assembly 40. The crossbeam assembly 40 has a mounting assembly 460 for mounting the calibration components. These calibration components on the crossbeam assembly 40 are used by the vehicle's sensors (cameras, radar, etc.) to assist in detecting sensor parameters. These calibration components can be calibration targets, radar calibration plates, night vision calibrators, and reflectors, etc.

[0058] The camera 50 has a shooting function. When the vehicle measuring equipment is working, it can take pictures of the ranging target to detect the distance between the vehicle measuring equipment and the ranging target. It can also take pictures of the targets at the wheels during four-wheel alignment. The camera 50 is mounted on the crossbeam assembly 40, and moves synchronously with the lifting and lowering of the crossbeam assembly 40.

[0059] The vehicle measuring device in the above embodiment includes a base assembly 10, a column assembly 20, a crossbeam assembly 40, a camera 50, and a mounting assembly 460. The camera 50 can be used to photograph the target on the wheel hub during four-wheel alignment to obtain wheel parameters, thus enabling four-wheel alignment. The camera 50 can also detect the distance between the ranging target and the vehicle measuring device. The mounting assembly 460 is used to mount calibration components for detection by sensors (cameras, radar, etc.) on the vehicle to assist in detecting sensor parameters, thus enabling ADAS calibration of the vehicle. Furthermore, the column assembly 20 includes a first column 21 and a second column 22 slidably connected to the first column 21, giving the crossbeam assembly 40 a large height travel range, making it suitable for both four-wheel alignment and ADAS calibration. The column assembly 20 can rotate relative to the base assembly 10, thereby adjusting the yaw angle of the crossbeam assembly 40 and reducing the structural complexity of other angle adjustment components.

[0060] In some embodiments of this application, please refer to Figures 2 and 3. The base assembly 10 further includes a first horizontal moving mechanism 11 and a second horizontal moving mechanism 12. The motion output end of the rotating mechanism 13 is fixedly connected to the first column 21, and the rotation axis of the motion output end of the rotating mechanism 13 is in the vertical direction. The first horizontal moving mechanism 11 is used to drive the second horizontal moving mechanism 12, the rotating mechanism 13 and the column assembly 20 to move in a first direction. The second horizontal moving mechanism 12 is used to drive the rotating mechanism 13 and the column assembly 20 to move in a second direction. The first direction and the second direction are perpendicular to each other and are both horizontal. An angle adjustment mechanism 30 is provided between the column assembly 20 and the crossbeam assembly 40. The angle adjustment mechanism 30 is at least used to adjust the pitch angle and tilt angle of the crossbeam assembly 40.

[0061] The first horizontal moving mechanism 11, the second horizontal moving mechanism 12, and the rotating mechanism 13 are connected by a transmission mechanism. This can be understood as the motion output end of the first horizontal moving mechanism 11 being connected to the second horizontal moving mechanism 12, and the motion output end of the second horizontal moving mechanism 12 being connected to the rotating mechanism 13. Thus, when the first horizontal moving mechanism 11 is working, the second horizontal moving mechanism 12, the rotating mechanism 13, the column assembly 20, and the crossbeam assembly 40 all move in a first direction, with the motion output end of the first horizontal moving mechanism 11 outputting linear motion in the X direction. When the second horizontal moving mechanism 12 is working, the rotating mechanism 13, the column assembly 20, and the crossbeam assembly 40 all move in a second direction, with the motion output end of the second horizontal moving mechanism 12 outputting linear motion in the Y direction. When the rotating mechanism 13 is working, its motion output end outputs rotational motion around the vertical direction, causing the column assembly 20 and the crossbeam assembly 40 to rotate around the vertical direction. Therefore, the position of the crossbeam assembly 40 in the X and Y directions, as well as its yaw angle, can be adjusted via the base assembly 10. The position of the crossbeam assembly 40 in the Z direction can be adjusted via the column assembly 20, and the angle adjustment mechanism 30 is used to adjust at least the pitch and roll angles of the crossbeam assembly 40. This achieves six degrees of freedom adjustment of the crossbeam assembly 40.

[0062] The base assembly 10 is equipped with a first horizontal moving mechanism 11, a second horizontal moving mechanism 12, and a rotating mechanism 13. This allows for the adjustment of the horizontal position of the column assembly 20 and the crossbeam assembly 40, as well as the adjustment of the lateral tilt angle of the crossbeam assembly 40. The angle adjustment mechanism 30 between the column assembly 20 and the crossbeam assembly 40 only needs to adjust the pitch angle and tilt angle of the crossbeam assembly 40. This simplifies the structure of the angle adjustment mechanism 30, facilitates its miniaturization, and avoids excessive use of the space between the column assembly 20 and the crossbeam assembly 40, thus making full use of the internal space of the base assembly 10.

[0063] In some embodiments, referring to FIG3, the first horizontal moving mechanism 11 is a second lead screw assembly. The second lead screw assembly includes a second motor, a second lead screw, a second nut block, and a second slide rail. The second motor outputs rotational motion to drive the second lead screw to rotate. The second nut block is threadedly connected to the second lead screw and slidably disposed on the second slide rail. Under the rotation of the second lead screw, the second nut block slides along the second slide rail in a first direction. The second nut block is the motion output end of the second lead screw assembly and is fixedly connected to the fixed part (such as a mounting plate or other structure) of the second horizontal moving mechanism 12.

[0064] In some embodiments, the first horizontal moving mechanism 11 is a gear and rack assembly, the rack is the motion output end of the first horizontal moving mechanism 11, and the rack is fixedly connected to the fixed part (such as a mounting plate or other structure) of the second horizontal moving mechanism 12.

[0065] In some embodiments, referring to Figure 3, the second horizontal moving mechanism 12 is a third lead screw assembly. The third lead screw assembly includes a third motor, a third lead screw, a third nut block, and a third slide rail. The third motor outputs rotational motion to drive the third lead screw to rotate. The third nut block is threadedly connected to the third lead screw and slidably disposed on the third slide rail. Under the rotation of the third lead screw, the third nut block slides along the third slide rail in a first direction. The third nut block is the motion output end of the third lead screw assembly and is fixedly connected to the fixed part (such as a mounting plate or other structure) of the rotating mechanism 13.

[0066] In some embodiments, the second horizontal moving mechanism 12 is a gear and rack assembly, the rack being the motion output end of the second horizontal moving mechanism 12, and the rack being fixedly connected to the fixed part (such as a mounting plate or other structure) of the rotating mechanism 13.

[0067] In some embodiments, referring to Figure 12, the rotating mechanism 13 includes a rotary motor, a worm gear, and a worm wheel. The worm gear is fixedly connected to the motion output end of the rotary motor, and the worm wheel meshes with the worm gear. The rotary motor outputs rotational motion, causing the worm gear to rotate. The worm gear rotates through the cooperation of the worm gear and the worm wheel. The worm wheel is the motion output end of the rotating mechanism 13. The worm wheel is connected to the column assembly 20, driving the column assembly 20 and the crossbeam assembly 40 to rotate in the vertical direction. The worm gear and worm wheel have a large transmission ratio and self-locking characteristics, which can drive the column assembly 20 and the crossbeam assembly 40 to rotate more stably. Moreover, it can change the direction of the motion output shaft of the rotating mechanism 13, which facilitates the internal structural layout of the base assembly 10.

[0068] In some embodiments, the rotating mechanism 13 includes a rotary motor, the motion output end of which is directly connected to the column assembly 20, driving the column assembly 20 and the beam assembly 40 to rotate in the vertical direction.

[0069] In some embodiments, referring to Figures 2 and 3, the base assembly 10 further includes a base housing 142 and a column base 141. The column base 141 is fixedly connected to the bottom of the first column 21 and is also fixedly connected to the motion output end of the rotating mechanism 13. The base housing 142 has an openable window at its top, which is covered by the column base 141. Thus, during the movement of the column assembly 20 relative to the base housing 142, the openable window remains covered, preventing the internal mechanisms of the base assembly 10 from being exposed.

[0070] In some embodiments of this application, please refer to Figures 4 and 5. The angle adjustment mechanism 30 includes an angle fixing seat 31, an angle adjustment seat 32, a rotating seat rotatably connected to the angle adjustment seat 32, a pitch adjustment assembly 33 and a tilt adjustment assembly 34, both disposed on the angle adjustment seat 32. The rotating seat is fixedly connected to the crossbeam assembly 40. The pitch adjustment assembly 33 includes a first rotating handwheel 331, a first bevel gear assembly 332 and a first worm gear assembly 333 connected in sequence. The first worm gear 3332 of the first worm gear assembly 333 is fixedly connected to the rotating seat. The tilt adjustment assembly 34 includes a second rotating handwheel 341, a second bevel gear assembly 342, a first lead screw assembly 343 and a rotating connecting rod 344 connected in sequence. One end of the rotating connecting rod 344 is rotatably connected to the linear output end of the first lead screw assembly 343, and the other end of the rotating connecting rod 344 is rotatably connected to the angle fixing seat 31.

[0071] Angle fixing seat 31 is slidably connected to column assembly 20 and can be fixed on mounting bracket 26. Angle adjusting seat 32 is rotatably connected to angle fixing seat 31 via rotating connecting rod 344. Specifically, one end of rotating connecting rod 344 is rotatably connected to the linear output end of first lead screw assembly 343, which is fixed on angle adjusting seat 32, and the other end of rotating connecting rod 344 is rotatably connected to angle fixing seat 31. When the second rotating handwheel 341 is rotated, the second bevel gear assembly 342 and the first lead screw assembly 343 are activated. The first lead screw assembly 343 outputs linear motion to rotating connecting rod 344, causing rotating connecting rod 344 to rotate, thereby pushing angle adjusting seat 32 to rotate relative to angle fixing seat 31, realizing the pitch movement of crossbeam assembly 40. The second rotating handwheel 341, the second bevel gear assembly 342, the first lead screw assembly 343, and the rotating connecting rod 344 are sequentially connected in a transmission manner. This means that the motion output end of the second rotating handwheel 341 is fixedly connected to the motion input end of the second bevel gear assembly 342, the motion output end of the second bevel gear assembly 342 is fixedly connected to the motion input end of the first lead screw assembly 343, and the motion output end of the first lead screw assembly 343 is rotatably connected to the rotating connecting rod 344.

[0072] When the first rotating handwheel 331 is rotated under force, it causes the first bevel gear assembly 332 and the first worm gear assembly 333 to work. The motion output end of the first worm gear assembly 333 is fixedly connected to the rotating seat, causing the rotating seat to rotate, which in turn drives the crossbeam assembly 40 to rotate, thereby achieving the tilting of the crossbeam assembly 40.

[0073] Rotating the first rotary handwheel 331 causes the rotating seat to rotate around the Y direction, achieving the tilting of the crossbeam assembly 40. Rotating the second rotary handwheel 341 causes the rotating seat to rotate around the X direction, achieving the pitching of the crossbeam assembly 40. Furthermore, both the pitch adjustment assembly 33 and the tilt adjustment assembly 34 are mounted on the angle adjustment seat 32. By changing the direction of motion in the transmission chain 25 through the first bevel gear assembly 332, the second bevel gear assembly 342, and the first worm gear assembly 333, both the pitch adjustment assembly 33 and the tilt adjustment assembly 34 have a flattened structure, resulting in a smaller overall thickness of the angle adjustment assembly, a more compact structure, and a smaller footprint.

[0074] In some embodiments, the rotating seat and the angle adjustment seat 32 are connected by a rotary bearing, which makes the rotating seat rotate more smoothly and with less resistance when rotating relative to the angle adjustment seat 32.

[0075] In some embodiments, referring to FIG5, the first bevel gear assembly 332 includes a first bevel gear 3321 and a second bevel gear 3322 meshing with each other; the first worm gear assembly 333 includes a first worm gear 3332 and a first worm 3331 meshing with each other; the first rotary handwheel 331 is coaxially and fixedly connected to the first bevel gear 3321; the second bevel gear 3322 is coaxially and fixedly connected to the first worm 3331; and the first worm gear 3332 is fixedly connected to the rotary seat. The rotation axis of the first rotary handwheel 331 is parallel to the X direction; the rotation axes of the first worm gear 3331 and the second bevel gear 3322 are parallel to the Z direction; and the rotation axis of the first worm gear 3332 is parallel to the Y direction, thus achieving the flattening of the pitch adjustment assembly 33.

[0076] In some embodiments, referring to FIG5, the second bevel gear assembly 342 includes a third bevel gear 3421 and a fourth bevel gear 3422 meshing with each other. The first lead screw assembly 343 includes a first lead screw 3431, a first nut block 3432, and a first slide rail 3433. The first nut block 3432 is threadedly connected to the first lead screw 3431 and slidably connected to the first slide rail 3433. The second rotating handwheel 341 is coaxially and fixedly connected to the third bevel gear 3421, and the fourth bevel gear 3422 is coaxially and fixedly connected to the first lead screw 3431. One end of the rotating connecting rod 344 is rotatably connected to the first nut block 3432. The rotation axis of the second rotating handwheel 341 is parallel to the X direction, the rotation axes of the first lead screw 3431 and the fourth bevel gear 3422 are parallel to the Z direction, and the movement direction of the first nut block 3432 is the Z direction, thus achieving the flattening of the tilt adjustment assembly 34.

[0077] In other embodiments, the first rotary handwheel 331 in the pitch adjustment assembly 33 can also be replaced by a power component such as an electrically driven motor. Similarly, the second rotary handwheel 341 in the tilt adjustment assembly 34 can also be replaced by a power component such as an electrically driven motor.

[0078] In some embodiments of this application, referring to Figure 4, the vehicle four-wheel alignment device further includes an altitude rangefinder 352 and a horizontal rangefinder 351. The altitude rangefinder 352 is used to detect the height position of the crossbeam assembly 40, and the horizontal rangefinder 351 is used to detect the horizontal distance between the crossbeam assembly 40 and the ranging target. The horizontal rangefinder 351 can be fixed to the bottom of the angle adjustment seat 32, and the altitude rangefinder 352 can be fixed to the outside of the angle fixing seat 31. Both the horizontal rangefinder 351 and the altitude rangefinder 352 can be laser rangefinders, emitting laser light that reflects off the target object, receiving the reflected laser light, and calculating the distance between the laser rangefinder and the target object based on the time difference between laser emission and reception.

[0079] In some embodiments of this application, please refer to FIG6. The column assembly 20 further includes a lifting drive 23 fixed to the first column 21, a transmission wheel 24 rotatably mounted on the second column 22, and a transmission chain 25 wound around the transmission wheel 24. The lifting drive 23 is used to drive the second column 22 to move up and down. One end of the transmission chain 25 is fixedly set, and the other end of the transmission chain 25 is connected to the crossbeam assembly 40.

[0080] The lifting drive component 23 is a power component capable of outputting linear motion. The transmission wheel 24 is self-rotating and mounted on the second column 22. The lifting drive component 23 moves up and down under the action of its motion output end connected to the second column 22. One end of the transmission chain 25 is fixed, and the other end is connected to the crossbeam assembly 40. The transmission chain 25 is wound around the transmission wheel 24. When the transmission wheel 24 moves up and down, it rotates simultaneously. Since one end of the transmission chain 25 remains stationary, the other end (the crossbeam assembly 40) moves with the up and down movement of the transmission wheel 24. Furthermore, the vertical displacement of the crossbeam assembly 40 is twice the vertical displacement of the transmission wheel 24. Specifically, when the lifting drive component 23 is working, the second column 22 moves a distance L relative to the first column 21. Correspondingly, the transmission wheel 24 moves a distance L relative to the first column 21, the crossbeam assembly 40 moves a distance 2L relative to the first column 21, and the crossbeam assembly 40 moves a distance L relative to the second column 22. Therefore, even when the length of the first column 21 is relatively short, it is still possible to achieve a large vertical stroke of the beam assembly 40, without having to make the first column 21 longer.

[0081] The crossbeam assembly 40 has a large travel range thanks to the cooperation of the drive wheel 24 and the drive chain 25. At the same time, the first column 21 is relatively short, which facilitates production and transportation.

[0082] In some embodiments, there are two drive wheels 24, which are respectively arranged on opposite sides of the second column 22. Correspondingly, there are also two drive chains 25, which pull the crossbeam assembly 40 up and down.

[0083] In some embodiments, referring to Figure 3, the second column 22 is frame-shaped and sleeved on the outside of the first column 21. The lifting drive 23 is fixed to the first column 21, and correspondingly, the lifting drive 23 is also located inside the second column 22. In this way, the internal space of the second column 22 can be fully utilized, making the spatial layout more compact.

[0084] In some embodiments of this application, please refer to Figures 6 to 8. The second column 22 includes two spaced-apart uprights 221 and a connecting plate 222 connecting the two uprights 221. The two uprights 221 are respectively disposed on opposite sides of the first column 21. The crossbeam assembly 40 is fixed to the transmission chain 25 by a mounting bracket 26. A guide wheel 263 is disposed between the mounting bracket 26 and the uprights 221.

[0085] The second column 22 includes two vertical plates 221 and a connecting plate 222. The vertical plates 221 are vertically arranged, and the two vertical plates 221 can be connected into a whole by the connecting plate 222. The crossbeam assembly 40 is fixed to the transmission chain 25 by the mounting bracket 26. It can be understood that the crossbeam assembly 40 is fixed to the mounting bracket 26, and the mounting bracket 26 is fixed to one end of the transmission chain 25. A guide wheel 263 is provided between the mounting bracket 26 and the vertical plates 221. The guide wheel 263 can be set on the mounting bracket 26 or the vertical plates 221, so that the mounting bracket 26 can move stably relative to the vertical plates 221.

[0086] By configuring the second column 22 as two upright plates 221 and a connecting plate 222, and allowing the opposite sides of the first column 21 to slide in contact with the two upright plates 221 respectively, the stability of the second column 22 during vertical movement can be improved. By providing guide wheels 263 between the mounting bracket 26 and the upright plates 221, the stability of the crossbeam assembly 40 during vertical movement can be improved.

[0087] In some embodiments, the connecting plate 222 is vertically arranged. When there are two connecting plates 222, the two connecting plates 222 and the two vertical plates 221 can be connected to form a frame-shaped structure.

[0088] In some embodiments, the connecting plate 222 is horizontally arranged, and the connecting plate 222 may be disposed on the top of the second column 22, and the transmission wheel 24 may be installed on the connecting plate 222.

[0089] In some embodiments, the second column 22 further includes a cover structure, which covers the top of the two uprights 221. The cover structure can shield the transmission wheel 24 and transmission chain 25, prevent foreign objects from falling into the transmission wheel 24 and transmission chain 25, and also has a certain dustproof function.

[0090] In some embodiments of this application, please refer to Figures 7 and 8. The upright plate 221 includes a first side wall portion 2211 and a second side wall portion 2212 that is bent and connected to the first side wall portion 2211. The connection between the first side wall portion 2211 and the second side wall portion 2212 forms an L-shaped limiting angle. The first column 21 extends toward the upright plate 221 to form a limiting portion 211 that cooperates with the limiting angle. One end of the transmission chain 25 is fixed to the limiting portion 211.

[0091] In some embodiments of this application, the mounting bracket 26 includes a first mounting plate 261 and two second mounting plates 262 respectively connected to opposite sides of the first mounting plate 261. The crossbeam assembly 40 is fixed to the first mounting plate 261. Guide wheels 263 are provided between the first mounting plate 261 and the first side wall portion 2211, and between the second mounting plate 262 and the second side wall portion 2212. The first side wall portion 2211 has a sliding groove 2213 extending in the vertical direction. The radial sides of the guide wheels 263 between the first mounting plate 261 and the first side wall portion 2211 are engaged in the sliding groove 2213.

[0092] The bending connection between the first sidewall portion 2211 and the second sidewall portion 2212 refers to the formation of an included angle between them, which can be a right angle, an acute angle, or an obtuse angle. The angle corresponding to the L-shaped limiting angle can be a right angle, an acute angle, or an obtuse angle. The limiting portion 211 extends into the interior of the limiting angle and abuts against the inner wall of the limiting angle (the wall surfaces of the first sidewall portion 2211 and the second sidewall portion 2212), forming a guide for the movement of the second column 22. A ring-shaped groove 2631 can be formed circumferentially on the guide wheel 263 between the first mounting plate 261 and the first sidewall portion 2211. When the guide wheel 263 is located in the slide groove 2213, the opposite sides of the slide groove 2213 abut against two opposite positions (radial sides) of the outer peripheral wall of the groove 2631.

[0093] The limiting angle formed by the upright plate 221, in conjunction with the limiting part 211 on the first upright column 21, makes the second upright column 22 more stable when moving up and down. By providing guide wheels 263 between the first mounting plate 261 and the first side wall part 2211, and between the second mounting plate 262 and the second side wall part 2212, firstly, the up and down movement of the mounting frame 26 relative to the second upright column 22 is more stable, and secondly, the sliding friction between the mounting frame 26 and the second upright column 22 is converted into rolling friction, making the movement of the mounting frame 26 and the crossbeam assembly 40 smoother.

[0094] In some embodiments, the upright plate 221 is connected to two opposite sides of each other by a second sidewall portion 2212, thus the second upright 22 has four second sidewall portions 2212, correspondingly forming four limiting angles as described above. The number of limiting portions 211 is the same as the number of limiting angles, and there are also four limiting portions 211. The four corner positions of the second upright 22 are all guided by the limiting portions 211 of the first upright 21, which can make the up-and-down movement of the second upright 22 more stable.

[0095] Optionally, the top plate of the first column 21 extends to form four limiting parts 211 at the four corners, which correspond to and cooperate with the four limiting corners.

[0096] In some embodiments, the first mounting plate 261 and the second mounting plate 262 are vertically connected, so that the mounting frame 26 is arranged in a U-shape. In this way, the mounting frame 26 and the second column 22 are more stably matched, and there are guide matching structures between the mounting frame 26 and the three sides of the second column 22.

[0097] In some embodiments, the guide wheel 263 is mounted on the mounting bracket 26 and can rotate relative to the mounting bracket 26. Alternatively, the guide wheel 263 is mounted on the second column 22 and can rotate relative to the second column 22.

[0098] In some embodiments, a plurality of guide wheels 263 are provided between a first mounting plate 261 and a first sidewall portion 2211, and a plurality of guide wheels 263 are provided between a second mounting plate 262 and a second sidewall portion 2212. The more guide wheels 263 there are, the more stable the movement of the second column 22 relative to the first column 21 will be.

[0099] In some embodiments of this application, please refer to Figures 9 and 12. The crossbeam assembly 40 includes a first crossbeam 41, a second crossbeam 42 rotatably connected to the first crossbeam 41, a first elastic member 451 with its two ends respectively connected to the first crossbeam 41 and the second crossbeam 42, a first locking assembly 43 and a second locking assembly 44. The crossbeam assembly 40 has a used state and a folded state. The first locking assembly 43 is used to lock the crossbeam assembly 40 in the used state, and the second locking assembly 44 is used to lock the crossbeam assembly 40 in the folded state.

[0100] The second crossbeam 42 is rotatably connected to the first crossbeam 41. When the first crossbeam 41 and the second crossbeam 42 are arranged in a straight line so that the crossbeam assembly 40 is fully extended (as shown in Figure 9), this state is called the usage state. When the first crossbeam 41 and the second crossbeam 42 are folded at an angle or folded to overlap, this state is called the folded state. During the rotation of the second crossbeam 42 relative to the first crossbeam 41, the first elastic element 451 can provide thrust for the rotation of the second crossbeam 42, and can also make the rotation of the second crossbeam 42 smoother and more stable.

[0101] The second crossbeam 42 can rotate relative to the first crossbeam 41, allowing the crossbeam assembly 40 to be folded and stored, facilitating its production, transportation, and storage. The first locking assembly 43 and the second locking assembly 44 ensure that the crossbeam assembly 40 can be stably maintained in either its operational or folded state.

[0102] In some embodiments, the first elastic element 451 is a gas spring or a hydraulic spring, which provides sufficient auxiliary force for the folding and unfolding of the second crossbeam 42.

[0103] In some embodiments, referring to Figures 9 to 14, the first locking component 43 and the second locking component 44 are respectively disposed on opposite sides of the crossbeam assembly 40 to prevent interference between the first locking component 43 and the second locking component 44. For example, the first locking component 43 is disposed on the upper side of the crossbeam assembly 40, and the second locking component 44 is disposed on the lower side of the crossbeam assembly 40.

[0104] In some embodiments of this application, please refer to FIG9, a gyroscope 452 is provided on the first crossbeam 41, and the gyroscope 452 can detect the placement angle of the crossbeam assembly 40.

[0105] Optionally, there are two gyroscopes 452, which are respectively set on opposite sides of the column assembly 20. The two gyroscopes 452 are symmetrically arranged, which makes the detection of the beam assembly 40 more accurate.

[0106] Optionally, there are two second crossbeams 42, which are rotatably connected to the two ends of the first crossbeam 41 respectively, and a camera 50 is fixed to the end of the second crossbeam 42 away from the first crossbeam 41.

[0107] In some embodiments, please refer to Figures 9 to 11. The first locking assembly 43 includes a first locking seat 431 fixed to the first crossbeam 41, a second locking seat 432 fixed to the second crossbeam 42, a hinge shaft 433, two pressing rods 434 hinged to each other by the hinge shaft 433, and a second elastic member with both ends connected to the two pressing rods 434 respectively. One end of the pressing rod 434 has a first engaging portion 4341, the second locking seat 432 has a second engaging portion 4321 that engages with the two first engaging portions 4341 respectively, and the other end of the pressing rod 434 has a first button portion 4342 for pressing.

[0108] The first locking seat 431 and the second locking seat 432 are respectively fixed to the first crossbeam 41 and the second crossbeam 42. A hinge shaft 433 is disposed on the first locking seat 431, and two pressing rods 434 are hinged together via the hinge shaft 433. One end of the pressing rod 434 has a first engaging portion 4341, which engages with the second engaging portion 4321 of the second locking seat 432. The other end of the pressing rod 434 has a first button portion 4342, which is used for pressing. Specifically, when the crossbeam assembly 40 is in use, the first engaging portion 4341 and the second engaging portion 4321 engage with each other, causing the second crossbeam 42 to be located along the length extension direction of the first crossbeam 41. When the crossbeam assembly 40 needs to be stored, press the two first button parts 4342 with two fingers at the same time to separate the two first latching parts 4341 from the second latching parts 4321 respectively, and then rotate the second crossbeam 42 to the folded state of the crossbeam assembly 40.

[0109] By setting two hinged push rods 434, the first locking part 4341 on the push rod 434 can be engaged with the second locking part 4321 of the second lock seat 432, or separated from the second locking part 4321, thereby realizing the locking and unlocking of the crossbeam assembly 40 in the use state.

[0110] In some embodiments, please refer to Figures 10 and 11. First button holes 4311 are provided on both sides of the first lock base 431. The first button part 4342 is located in the corresponding first button hole 4311, so that the first button part 4342 is exposed, which is convenient for the user to press. Pressing both first button parts 4342 at the same time can unlock the crossbeam assembly 40 in use.

[0111] In some embodiments, referring to FIG11, the same end of the two pressing rods 434 extends toward each other to form a hook-shaped first engaging portion 4341, and the second locking seat 432 extends toward the first locking seat 431 to form a second engaging portion 4321. The opposite sides of the second engaging portion 4321 are recessed to form a slot, and the second engaging portion 4321 is arrow-shaped, so that the two first engaging portions 4341 can be more smoothly engaged into the inside of the slot along the sides of the pliers-like structure.

[0112] In some embodiments, as shown in Figure 11, the length direction of the hinge shaft 433 is parallel to the vertical direction, and the rotation axis of the pressing rod 434 is also vertical, so as not to affect the folding and unfolding of the second crossbeam 42.

[0113] In some embodiments, the second elastic element is a torsion spring, and the second elastic element is sleeved on the hinge shaft 433, which can provide clamping force for the engagement of the first snap-fit ​​portion 4341 and the second snap-fit ​​portion 4321.

[0114] In some embodiments of this application, please refer to Figures 12 to 14. The second locking assembly 44 includes a third locking seat 441 fixed to the first crossbeam 41, a fourth locking seat 442 fixed to the second crossbeam 42, a sliding structure 443 slidably disposed on the third locking seat 441, and a third elastic member 444 with its two ends respectively connected to the sliding structure 443 and the third locking seat 441. The third locking seat 441 and the fourth locking seat 442 are hinged to each other. The sliding structure 443 has a third engaging portion 4431 and a second button portion 4432 for pressing. The fourth locking seat 442 has a fourth engaging portion 4421 that engages with the third engaging portion 4431. When the third engaging portion 4431 and the fourth engaging portion 4421 are engaged, the first crossbeam 41 and the second crossbeam 42 are perpendicular to each other.

[0115] The third locking seat 441 and the fourth locking seat 442 are respectively fixed to the first crossbeam 41 and the second crossbeam 42, and the sliding structure 443 can slide relative to the third locking seat 441. When the crossbeam assembly 40 is in use, the third locking part 4431 and the fourth locking part 4421 are separated. When the crossbeam assembly 40 needs to be stored, the first locking component 43 is unlocked, and then the second crossbeam 42 is rotated until it is perpendicular to the first crossbeam 41, at which point the third locking part 4431 and the fourth locking part 4421 are locked together. When the crossbeam assembly 40 needs to be switched to the use state, the second button part 4432 is pressed, the third elastic member 444 is compressed, the third locking part 4431 and the fourth locking part 4421 disengage, and then the second crossbeam 42 is rotated to switch the crossbeam assembly 40 to the use state, at which point the first locking part 4341 and the second locking part 4321 are locked together.

[0116] By setting a sliding structure 443 that can slide relative to the third locking seat 441, the third locking part 4431 and the fourth locking part 4421 can be locked or separated from each other, thereby realizing the locking and unlocking of the crossbeam assembly 40 in the folded state.

[0117] In some embodiments, please refer to FIG14. The third lock seat 441 includes a lock seat body 4411 and a lock seat cover 4412. The third elastic member 444 and the sliding structure 443 are both disposed inside the lock seat body 4411. The lock seat cover 4412 has a second button hole 4413. The second button part 4432 extends into the second button hole 4413, making it convenient for the user to press the second button part 4432.

[0118] In some embodiments, please refer to FIG14, the sliding structure 443 moves in a vertical direction. When the sliding structure 443 moves in a vertical direction, the third locking part 4431 and the fourth locking part 4421 can be locked or disengaged from each other, without affecting the unfolding and folding of the crossbeam assembly 40.

[0119] In some embodiments of this application, please refer to Figures 9 and 12. There are two second crossbeams 42, each rotatably connected to both ends of the first crossbeam 41. A camera 50 is fixed to the end of the second crossbeam 42 furthest from the first crossbeam 41. Understandably, both ends of the crossbeam assembly 40 can be folded, shortening its length and creating a symmetrical structure, resulting in more balanced stress even when folded.

[0120] Optionally, the first crossbeam 41 is symmetrically arranged with respect to the column assembly 20, and the two second crossbeams 42 are also symmetrically arranged with respect to the column assembly 20, so as to facilitate the adjustment of the position and angle of the shooting camera 50.

[0121] In other embodiments, the number of second crossbeams 42 may also be one, disposed at one end of the first crossbeam 41.

[0122] In some embodiments of this application, please refer to Figures 12 and 15. The mounting assembly 460 includes a first mounting structure 46 that is snapped onto the crossbeam assembly 40 and can slide relative to the crossbeam assembly 40. The first mounting structure 46 includes a mounting plate 461 and a sliding snap-fit ​​structure 463 fixed to the mounting plate 461. The mounting plate 461 has a mounting hole 4611 for mounting a calibration component.

[0123] The first mounting structure 46 is snapped onto the crossbeam assembly 40 during use and can slide relative to the crossbeam assembly 40. The sliding direction of the first mounting structure 46 is the length direction of the crossbeam assembly 40. Therefore, the horizontal position of the first mounting structure 46 can be changed, and the horizontal position of the calibration component attached to the first mounting structure 46 can also be changed. The first mounting structure 46 includes a mounting plate 461 and a sliding snap-fit ​​structure 463. The sliding snap-fit ​​structure 463 allows the first mounting structure 46 to slide and snap onto the crossbeam assembly 40, while the mounting plate 461 is used to attach the calibration component. Specifically, the back of the calibration component generally has a protruding mounting protrusion. The mounting protrusion is inserted into the mounting hole 4611, which can stably attach the calibration component to the mounting plate 461.

[0124] By providing a sliding snap-fit ​​structure 463 on the first hook-fit structure 46, the first hook-fit structure 46 can slide relative to the crossbeam assembly 40, thereby adjusting the horizontal position of the first hook-fit structure 46, and also enabling the first hook-fit structure 46 to be stably snapped onto the crossbeam assembly 40, and the first hook-fit structure 46 can also be removed from the crossbeam assembly 40 as needed.

[0125] In some embodiments, referring to FIG15, a hanging hole 4611 is provided on the top side of the mounting plate 461, and is formed by a downward indentation of the top side of the mounting plate 461. The mounting protrusion has a neck with a smaller diameter than other locations, and the neck of the mounting protrusion is inserted into the hanging hole 4611.

[0126] In some embodiments, please refer to FIG15, there are multiple hanging holes 4611, and the multiple hanging holes 4611 are arranged sequentially along the length direction of the crossbeam assembly 40, which can make the calibration component more stable when it is hung on the mounting plate 461.

[0127] In some embodiments of this application, please refer to Figures 12 and 17. The mounting assembly 460 further includes a support structure 48. One end of the support structure 48 is rotatably connected to the beam assembly 40, and the other end of the support structure 48 has a support protrusion 481 for supporting the calibration member. A first snap-fit ​​structure 411 is fixed on the beam assembly 40, and a second snap-fit ​​structure 482 is provided on the support structure 48. The first snap-fit ​​structure 411 and the second snap-fit ​​structure 482 snap-fit ​​each other, so that the support structure 48 is positioned close to the beam assembly 40.

[0128] The support structure 48 is used to support the bottom of the calibration component. When the calibration component is large or heavy, the support structure 48 can reduce the shaking of the calibration component. The support structure 48 has a working state and a stored state. When the support structure 48 is rotated relative to the crossbeam assembly 40 until the first locking structure 411 and the second locking structure 482 are engaged, the support structure 48 is close to the crossbeam assembly 40 and is in the stored state. When the support structure 48 is rotated relative to the crossbeam assembly 40 until the support structure 48 is perpendicular to the crossbeam assembly 40, the support protrusion 481 of the support structure 48 abuts against the bottom side of the calibration component, and the support structure 48 is in the working state.

[0129] By setting up the support structure 48, the base plate of the calibration component can be supported, making the calibration component more stable and reducing its shaking. Moreover, the support structure 48 can be rotated to a retracted state and engaged with the crossbeam assembly 40, meaning that when the support structure 48 is not needed, it can be rotated and retracted without affecting other testing operations of the calibration equipment.

[0130] In some embodiments, as shown in Figures 12 and 17, the support protrusion 481 can both support the bottom of the calibration member and be held by the user. When it is necessary to rotate the support structure 48, the user can hold the support protrusion 481 to rotate the support structure 48.

[0131] Optionally, the supporting protrusion 481 can be a cylindrical structure, a cuboid structure, or the like.

[0132] In some embodiments, the surface of the support protrusion 481 is provided with an alignment groove. When the support structure 48 is in use, the bottom edge of the calibration member is inserted into the interior of the alignment groove, so that the calibration member can be kept in a vertical state to prevent the calibration member from having an unexpected pitch posture.

[0133] In some embodiments, one of the first snap-fit ​​structure 411 and the second snap-fit ​​structure 482 is a protruding structure and the other is a recessed structure. Referring to Figure 5, the first snap-fit ​​structure 411 is a recessed structure and the second snap-fit ​​structure 482 is a protruding structure.

[0134] Optionally, a ball is provided on the inner wall of the recessed structure, and the top dimension of the protruding structure is larger than its root dimension. As the protruding structure gradually enters the recessed structure, the ball is pressed tightly. After the protruding structure is in place, the dimension of the protruding structure opposite the ball is smaller than its maximum dimension. The ball presses the protruding structure, so that the protruding structure is locked in the recessed structure.

[0135] Alternatively, the protrusion structure can be spherical or disc-shaped.

[0136] In some embodiments of this application, please refer to Figures 12 and 16. The mounting assembly 460 further includes a second mounting structure 47 that is snapped onto the crossbeam assembly 40 and can slide relative to the crossbeam assembly 40. There are two second mounting structures 47, which are respectively disposed on opposite sides of the first mounting structure 46. The second mounting structure 47 includes a limiting plate 471 and a sliding snap-fit ​​structure 463 fixed to the limiting plate 471. The limiting plate 471 has a limiting groove 4711 for snapping onto the side wall of the calibration component on the side facing the calibration component.

[0137] The second mounting structure 47 is used to limit the side of the calibration component. The second mounting structure 47 can be snapped onto the crossbeam assembly 40 or slide relative to the crossbeam assembly 40, that is, the position of the second mounting structure 47 on the crossbeam assembly 40 can be adjusted. The second mounting structure 47 includes a limiting plate 471 and a sliding snap structure 463. The sliding snap structure 463 allows the entire second mounting structure 47 to be slidably snapped onto the crossbeam assembly 40. The limiting plate 471 has a limiting groove 4711. When using the second mounting structure 47, the side edge of the calibration component extends into the limiting groove 4711.

[0138] When the calibration component to be attached is large, it is easy for the calibration component to wobble. Attaching the calibration component with only the first attachment structure 46 is not stable. By using two second attachment structures 47 to limit the left and right sides of the calibration component respectively, the calibration component can be made more stable.

[0139] In some embodiments, the limiting groove 4711 extends along the side wall of the limiting plate 471, so that the limiting groove 4711 extends to the upper and lower sides of the limiting plate 471, and the limiting plate 471 can be engaged at any position on the side wall of the calibration component.

[0140] In some embodiments, the first mounting structure 46 is disposed in the middle of the crossbeam assembly 40, and two second mounting structures 47 are respectively disposed on opposite sides of the first mounting structure 46, so that the calibration components are placed symmetrically.

[0141] In some embodiments of this application, the sliding snap-fit ​​structure 463 includes a fixed base 4633, a clamping member 4632, a clamping elastic member 4634, and a lever 4636. The fixed base 4633 is fixed to the mounting plate 461 or the limiting plate 471. The two ends of the clamping elastic member 4634 are respectively connected to the fixed base 4633 and the clamping member 4632. The clamping member 4632 is clamped to the opposite sides of the crossbeam assembly 40 by the clamping elastic member 4634. The lever 4636 is hinged to the mounting plate 461 or the limiting plate 471, and one end of the lever 4636 has a pushing part 46361. The pushing part 46361 is used to push the clamping member 4632 to separate the clamping member 4632 from the crossbeam assembly 40.

[0142] For ease of explanation, the mounting plate 461 and the limiting plate 471 can be collectively referred to as the fixed structure. The sliding snap-fit ​​structure 463 is fixed to the fixed structure. Specifically, the fixing seat 4633 is fixed to the fixed structure. In the first mounting structure 46, the fixing seat 4633 is fixed to the mounting plate 461; in the second mounting structure 47, the fixing seat 4633 is fixed to the limiting plate 471. When the lever 4636 is turned, the pushing part 46361 on the lever 4636 pushes the clamping member 4632, causing the clamping member 4632 to separate from the crossbeam assembly 40. The mounting structure is unlocked from the crossbeam assembly 40, pushing the first mounting structure 46 and the second mounting structure 47 to the predetermined position, and then the lever 4636 is returned to the initial position.

[0143] The clamping elastic element 4634 presses the clamping element 4632 against the crossbeam assembly 40, and simultaneously cooperates with the scale 4631 to achieve the locking of the hanging structure onto the crossbeam assembly 40. Furthermore, the compression amount of the clamping elastic element 4634 can be controlled by the movement of the lever 4636, thereby enabling quick control of locking and unlocking of the hanging structure.

[0144] In some embodiments, please refer to Figures 15 and 16. The clamping member 4632 has a friction surface on one side for clamping the crossbeam assembly 40. The static friction between the friction surface and the crossbeam assembly 40 is large, which can make the first hook structure 46 and the second hook structure 47 more stably hooked onto the crossbeam assembly 40.

[0145] Optionally, the friction surface is the surface of the clamping part 4632, which can be formed by roughening treatment, and its surface roughness is relatively large.

[0146] Optionally, the friction surface is the surface of the friction plate 4637, which is fixed to the clamping member 4632 and used to press against the crossbeam assembly 40. The surface of the friction plate 4637 is rough, resulting in a large static friction force between it and the crossbeam assembly 40.

[0147] In some embodiments, referring to Figures 15 and 16, a pushing part 46361 is disposed at one end of a lever 4636. The pushing part 46361 has two spaced-apart pushing claws 46362, which are spaced apart in a direction parallel to the length of the crossbeam assembly 40. Thus, the pushing part 46361 has a relatively large dimension in the length direction of the crossbeam assembly 40, allowing the lever 4636 to push and clamp the elastic member 4634 by swinging it left or right. Furthermore, when the external force is lost, the lever 4636 automatically returns to its original position and locks itself onto the crossbeam assembly 40 to prevent the hanging structure from falling off the crossbeam assembly 40.

[0148] In some embodiments, referring to Figures 15 and 16, when the lever 4636 is vertically positioned, the first hook structure 46 and the second hook structure 47 are locked and fixed to the crossbeam assembly 40; when the lever 4636 is tilted, the first hook structure 46 and the second hook structure 47 are unlocked and can slide relative to the crossbeam assembly 40. This allows the user to easily identify the current state of the hook structure.

[0149] In some embodiments, referring to Figures 15 and 16, the sliding snap-fit ​​structure 463 further includes a guide rod 4635. One end of the guide rod 4635 is fixed to the clamping member 4632, and the other end of the guide rod 4635 passes through the fixing seat 4633. The clamping elastic member 4634 is sleeved on the guide rod 4635. The guide rod 4635 makes the unlocking and locking process (up and down movement) of the clamping member 4632 more stable and also provides an installation position for the clamping elastic member 4634.

[0150] In some embodiments, referring to Figures 15 and 16, the sliding latching structure 463 further includes a scale 4631 with graduations. The scale 4631 has graduations, and the crossbeam assembly 40 has corresponding graduations. The scale 4631 facilitates the user to read and obtain the current position of the latching structure. In the first latching structure 46, the scale 4631 is fixed to the latching plate 461; in the second latching structure 47, the scale 4631 is fixed to the limiting plate 471.

[0151] In some embodiments of this application, please refer to FIG12, the crossbeam assembly 40 has a slide rail 49, and the first hook structure 46 and the second hook structure 47 are both mounted on the slide rail 49, and the first hook structure 46 and the second hook structure 47 are both slidably disposed on the slide rail 49.

[0152] In some embodiments of this application, referring to Figure 1, the vehicle measuring device further includes a flat plate mounting structure 60 fixed to the first column. The flat plate mounting structure 60 is used to mount and fix the flat plate, which can wirelessly connect to the vehicle system, facilitating real-time adjustment of vehicle parameters during the testing process. The flat plate mounting structure 60 can clamp, place, or support the flat plate, etc., and the specific structure of the flat plate mounting structure 60 is not limited here.

[0153] In some embodiments, the plate mounting structure 60 is an inclined plate, and the bottom of the inclined plate has an edge stop for stopping the bottom of the plate.

[0154] In some embodiments of this application, please refer to Figures 1 and 6. The vehicle measuring device also includes a control module, a display device 70, and a button structure 80. The display device 70 and the button structure 80 are both electrically connected to the control module. The button structure 80 is disposed on the first column 21 and is used to control the base assembly 10 and the column assembly 20.

[0155] The control module serves as the data processing system for the vehicle measuring equipment. It is electrically connected to the button structure 80, display device 70, base assembly 10, and column assembly 20. The button structure 80 can control the movement of the base assembly 10 and column assembly 20. For example, it can control the base assembly 10 to move the column assembly 20 horizontally in a first direction and a second direction, to rotate the column assembly 20, and to move the crossbeam assembly 40 up and down relative to the first column 21. The button structure 80 can also control the start and stop of the vehicle measuring equipment. The display device is used to display the parameters detected and set by the measuring equipment.

[0156] The vehicle measuring equipment can be automatically controlled through the control module, display device 70, and button structure 80, making the vehicle measuring equipment easier to operate.

[0157] In some embodiments, the control module may be located inside the first column 21. The control module may be a motherboard, which has a switch structure that corresponds one-to-one with the buttons of the button structure 80.

[0158] In some embodiments, the display device 70 is a structure such as a monitor or a display panel.

[0159] In some embodiments, the button structure 80 is a physical robotic arm button switch or rotary switch, or it can be a touch-type capacitive switch.

[0160] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
