[0046] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0047] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0048] It should be understood that the orientation or position relationship indicated by terms such as "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0049] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0050] The intelligent driving system of a car can assist or completely replace the driver's driving. Therefore, a car with an intelligent driving system generally has sensors such as radar and cameras, and the parameters of sensors, wheels and other components need to be calibrated and calibrated. Each component requires different calibration equipment. Therefore, more equipment is required for calibration and the equipment cost is also high.

[0051] In order to solve the above technical problems, the present invention proposes an intelligent vehicle measuring device, wherein a shooting camera 50 and a hanging assembly 460 for hanging a calibration part are arranged on the crossbeam assembly, the length of the column assembly 20 is variable, and the adjustment range of the crossbeam assembly 40 is large, which can be suitable for four-wheel alignment detection and ADAS calibration at the same time.

[0052] The vehicle measurement device provided by the embodiment of the present invention is now described.

[0053] Please also read Figures 1 to 3 The vehicle measuring device includes a base assembly 10, a column assembly 20 arranged on the base assembly 10, a beam assembly 40 arranged on the column assembly 20, a shooting camera 50 fixed on the beam assembly 40, and a hanging assembly 460 arranged on the beam assembly 40 and used to hang the calibration part. 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 beam assembly 40 is driven to rise and fall by the second column 22.

[0054] The base assembly 10 is generally used to be placed on the ground to support the column assembly 20, so as to facilitate the movement of the vehicle measurement equipment and make the vehicle measurement equipment more stable when placed. The base assembly 10 includes a rotating mechanism 13 capable of outputting a rotational motion, and the rotating mechanism 13 has a motion output end of the 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.

[0055] The column assembly 20 is disposed on the base assembly 10. The column assembly 20 is generally a vertically disposed long strip structure, and is used to support the cross beam assembly 40 so that the cross beam assembly 40 is 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 when the second column 22 is lifted and lowered, the cross beam assembly 40 is also lifted and lowered. In this way, the vertical stroke of the cross beam assembly 40 can be increased without increasing the length of the column assembly 20 (the minimum length when retracted), so that it can perform four-wheel alignment and ADAS detection at the same time.

[0056] The height of the crossbeam assembly 40 is variable and can be raised and lowered relative to the column assembly 20. When the vehicle is calibrated for ADAS or four-wheel alignment, the height of the crossbeam assembly 40 can be adjusted by raising and lowering the crossbeam assembly 40, thereby adjusting the height of the calibration part on the crossbeam assembly 40. The crossbeam assembly 40 has a hanging assembly 460, which is used to hang the calibration part. The calibration part on the crossbeam assembly 40 is used for detection by sensors (cameras, radars, etc.) on the vehicle to assist in detecting the parameters of the sensors. Among them, the calibration part can be a calibration target, a radar calibration plate, a night vision calibrator, a reflector, etc.

[0057] The shooting camera 50 has a shooting function. When the vehicle measuring device is working, it can take a picture of the distance measuring target to detect the distance between the vehicle measuring device and the distance measuring target. It can also take a picture of the target at the wheel during four-wheel alignment. The shooting camera 50 is set on the crossbeam assembly 40. When the crossbeam assembly 40 is raised or lowered, the shooting camera 50 moves synchronously.

[0058] The vehicle measuring device in the above embodiment includes a base assembly 10, a column assembly 20, a beam assembly 40, a camera 50 and a hook assembly 460. The camera 50 can be used to take pictures of the target on the wheel hub during four-wheel alignment to obtain the parameters of the wheel, that is, four-wheel alignment can be performed. The camera 50 can also detect the distance between the distance measuring target and the vehicle measuring device. The hook assembly 460 is used to hang the calibration parts for the sensors (camera, radar, etc.) on the vehicle to detect and assist in detecting the parameters of the sensors, that is, ADAS calibration can be performed on the vehicle. Moreover, the column assembly 20 includes a first column 21 and a second column 22 slidably connected to the first column 21, so that the beam assembly 40 has a large height movement stroke, which can be used for four-wheel alignment and ADAS calibration at the same time. The column assembly 20 can rotate relative to the base assembly 10, and then the yaw angle of the beam assembly 40 can be adjusted, reducing the structural complexity of other angle adjustment components.

[0059] In some embodiments of the present invention, see Figure 2 and Figure 3The base assembly 10 also 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 the first direction. The second horizontal moving mechanism 12 is used to drive the rotating mechanism 13 and the column assembly 20 to move in the second direction. The first direction and the second direction are perpendicular to each other and are both horizontal directions. An angle adjustment mechanism 30 is arranged between the column assembly 20 and the beam assembly 40. The angle adjustment mechanism 30 is at least used to adjust the pitch angle and roll angle of the beam assembly 40.

[0060] The first horizontal moving mechanism 11, the second horizontal moving mechanism 12 and the rotating mechanism 13 are connected in transmission, which can be understood as that the motion output end of the first horizontal moving mechanism 11 is connected to the second horizontal moving mechanism 12, and the motion output end of the second horizontal moving mechanism 12 is connected to the rotating mechanism 13. In this way, 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 beam assembly 40 all move in the first direction, and the motion output end of the first horizontal moving mechanism 11 outputs linear motion, and the first direction is the X direction. When the second horizontal moving mechanism 12 is working, the rotating mechanism 13, the column assembly 20 and the beam assembly 40 all move in the second direction, and the motion output end of the second horizontal moving mechanism 12 outputs linear motion, and the second direction is the Y direction. When the rotating mechanism 13 is working, the motion output end of the rotating mechanism 13 outputs a motion rotating around the vertical direction, so that the column assembly 20 and the beam assembly 40 both rotate around the vertical direction. In this way, the position of the beam assembly 40 in the X direction and the Y direction can be adjusted through the base assembly 10, and the yaw angle of the beam assembly 40 can be adjusted. The position of the beam assembly 40 in the Z direction can be adjusted by the column assembly 20, and the angle adjustment mechanism 30 is used to at least adjust the pitch angle and roll angle of the beam assembly 40. In this way, the six-degree-of-freedom adjustment of the beam assembly 40 is achieved.

[0061] A first horizontal moving mechanism 11, a second horizontal moving mechanism 12 and a rotating mechanism 13 are arranged inside the base assembly 10, so as to realize horizontal position adjustment of the column assembly 20 and the beam assembly 40 and yaw angle adjustment of the beam assembly 40. The angle adjustment mechanism 30 between the column assembly 20 and the beam assembly 40 only needs to adjust the pitch angle and roll angle of the beam assembly 40, so that the structure of the angle adjustment mechanism 30 is simple, which is conducive to the miniaturization of the angle adjustment mechanism 30, does not occupy too much space between the column assembly 20 and the beam assembly 40, and makes full use of the internal space of the base assembly 10.

[0062] In some embodiments, see Figure 3The first horizontal moving mechanism 11 is a second screw assembly, which includes a second motor, a second screw, a second nut block and a second slide rail. The second motor outputs a rotational motion to drive the second screw to rotate. The second nut block is threadedly connected to the second screw, and the second nut block is slidably arranged on the second slide rail. Under the rotation of the second screw, the second nut block slides in the first direction along the second slide rail. The second nut block is the motion output end of the second screw assembly, and the second nut block is fixedly connected to the fixed part (such as a mounting plate or other structure) of the second horizontal moving mechanism 12.

[0063] In some embodiments, the first horizontal moving mechanism 11 is a gear 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 of the second horizontal moving mechanism 12 (such as a mounting plate or other structure).

[0064] In some embodiments, see Figure 3 The second horizontal moving mechanism 12 is a third screw assembly, which includes a third motor, a third screw, a third nut block and a third slide rail. The third motor outputs a rotational motion to drive the third screw to rotate. The third nut block is threadedly connected to the third screw, and the third nut block is slidably arranged on the third slide rail. Under the rotation of the third screw, the third nut block slides in the first direction along the third slide rail. The third nut block is the motion output end of the third screw assembly, and the third nut block is fixedly connected to the fixed part (such as a mounting plate or other structure) of the rotating mechanism 13.

[0065] In some embodiments, the second horizontal moving mechanism 12 is a gear rack assembly, the rack is the motion output end of the second horizontal moving mechanism 12, and the rack is fixedly connected to the fixed part of the rotating mechanism 13 (such as a mounting plate or other structure).

[0066] In some embodiments, see Fig.12 The rotating mechanism 13 includes a rotating motor, a worm and a worm wheel. The worm is fixedly connected to the motion output end of the rotating motor. The worm wheel and the worm are meshed with each other. The rotating motor outputs a rotating motion to rotate the worm. The worm wheel rotates through the cooperation of the worm 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 beam assembly 40 to rotate around the vertical direction. The cooperation of the worm wheel and the worm has a large transmission ratio and self-locking characteristics, which can drive the column assembly 20 and the beam assembly 40 to rotate more stably, and can also change the direction of the motion output shaft of the rotating mechanism 13, which is convenient for the internal structural layout of the base assembly 10.

[0067] In some embodiments, the rotating mechanism 13 includes a rotating motor, and a motion output end of the rotating motor is directly connected to the column assembly 20 to drive the column assembly 20 and the beam assembly 40 to rotate around the vertical direction.

[0068] In some embodiments, see Figure 2 and Figure 3 The base assembly 10 further includes a base shell 142 and a column base 141. The column base 141 is fixedly connected to the bottom of the first column 21, and the column base 141 is fixedly connected to the motion output end of the rotating mechanism 13. A movable window is provided at the top of the base shell 142, and the column base 141 shields the movable window. In this way, during the movement of the column assembly 20 relative to the base shell 142, the movable window is always kept in a shielded state to prevent the internal mechanism of the base assembly 10 from being exposed.

[0069] In some embodiments of the present invention, see Figure 4 and Figure 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 component 33 and a roll adjustment component 34, both of which are arranged on the angle adjustment seat 32, and the rotating seat is fixedly connected to the crossbeam component 40; the pitch adjustment component 33 includes a first rotating hand wheel 331, a first bevel gear component 332 and a first worm gear component 333, which are sequentially connected in transmission, and the first worm wheel 3332 of the first worm gear component 333 is fixedly connected to the rotating seat; the roll adjustment component 34 includes a second rotating hand wheel 341, a second bevel gear component 342, a first screw assembly 343 and a rotating connecting rod 344, which are sequentially connected in transmission, one end of the rotating connecting rod 344 is rotatably connected to the linear output end of the first screw assembly 343, and the other end of the rotating connecting rod 344 is rotatably connected to the angle fixing seat 31.

[0070] The angle fixing seat 31 is slidably connected to the column assembly 20, and the angle fixing seat 31 can be fixed on the mounting frame 26. The angle adjustment seat 32 is rotatably connected to the angle fixing seat 31 through the rotating connecting rod 344. Specifically, one end of the rotating connecting rod 344 is rotatably connected to the linear output end of the first screw assembly 343, and the first screw assembly 343 is fixed on the angle adjustment seat 32, and the other end of the rotating connecting rod 344 is rotatably connected to the angle fixing seat 31. When the second rotating hand wheel 341 is rotated, the second bevel gear assembly 342 and the first screw assembly 343 are operated, and the first screw assembly 343 outputs linear motion to the rotating connecting rod 344, so that the rotating connecting rod 344 rotates, thereby pushing the angle adjustment seat 32 to rotate relative to the angle fixing seat 31, and realizing the pitching motion of the beam assembly 40. Among them, the second rotating handwheel 341, the second bevel gear assembly 342, the first screw assembly 343 and the rotating connecting rod 344 are sequentially connected in transmission, which 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 screw assembly 343, and the motion output end of the first screw assembly 343 is rotationally connected to the rotating connecting rod 344.

[0071] When the first rotating hand wheel 331 is rotated under force, the first bevel gear assembly 332 and the first worm gear assembly 333 work, and the motion output end of the first worm gear assembly 333 is fixedly connected to the rotating seat, so that the rotating seat rotates, thereby driving the beam assembly 40 to rotate, thereby realizing the tilting of the beam assembly 40.

[0072] By rotating the first rotating hand wheel 331, the rotating seat rotates around the Y direction to achieve the roll of the beam assembly 40, and by rotating the second rotating hand wheel 341, the rotating seat rotates around the X direction to achieve the pitch of the beam assembly 40. Moreover, the pitch adjustment assembly 33 and the roll adjustment assembly 34 are both arranged on the angle adjustment seat 32, and the movement direction in the transmission chain 25 is changed by the first bevel gear assembly 332, the second bevel gear assembly 342, and the first worm gear assembly 333, so that the pitch adjustment assembly 33 and the roll adjustment assembly 34 are both flat structures, so that the overall thickness of the angle adjustment assembly is small, the structure is more compact, and the space occupied is smaller.

[0073] In some embodiments, the rotating seat and the angle adjustment seat 32 are connected via a rotating bearing, so that the rotating seat rotates more smoothly and with less resistance relative to the angle adjustment seat 32 .

[0074] In some embodiments, see Figure 5 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 wheel 3332 and a first worm 3331 meshing with each other, the first rotating hand wheel 331 is coaxially fixedly connected to the first bevel gear 3321, the second bevel gear 3322 is coaxially fixedly connected to the first worm 3331, and the first worm wheel 3332 is fixedly connected to the rotating seat. The rotation axis of the first rotating hand wheel 331 is parallel to the X direction, the rotation axes of the first worm 3331 and the second bevel gear 3322 are parallel to the Z direction, and the rotation axis of the first worm wheel 3332 is parallel to the Y direction, so that the pitch adjustment assembly 33 is flattened.

[0075] In some embodiments, see Figure 5The 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 the first nut block 3432 is slidably connected to the first slide rail 3433, the second rotating hand wheel 341 is coaxially fixedly connected to the third bevel gear 3421, the fourth bevel gear 3422 is coaxially fixedly connected to the first lead screw 3431, and one end of the rotating connecting rod 344 is rotatably connected to the first nut block 3432. The rotation axis of the second rotating hand wheel 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 moving direction of the first nut block 3432 is the Z direction, so that the roll adjustment assembly 34 is flattened.

[0076] In other embodiments, the first rotating hand wheel 331 in the pitch adjustment assembly 33 may also be replaced by a power component such as an electrically driven motor. The second rotating hand wheel 341 in the roll adjustment assembly 34 may also be replaced by a power component such as an electrically driven motor.

[0077] In some embodiments of the present invention, see Figure 4 The vehicle four-wheel alignment device also includes a height rangefinder 352 and a horizontal rangefinder 351. The height rangefinder 352 is used to detect the height position of the beam assembly 40, and the horizontal rangefinder 351 is used to detect the horizontal distance between the beam assembly 40 and the distance measurement target. The horizontal rangefinder 351 can be fixed to the bottom of the angle adjustment seat 32, and the height rangefinder 352 can be fixed to the outside of the angle fixing seat 31. The horizontal rangefinder 351 and the height rangefinder 352 can both be laser rangefinders, which emit laser light and reflect after reaching the target object, receive the reflected laser light, and calculate the distance between the laser rangefinder and the target object through the time difference between the laser emission and reception.

[0078] In some embodiments of the present invention, see Figure 6 The column assembly 20 also includes a lifting drive member 23 fixed to the first column 21, a transmission wheel 24 rotatably installed on the second column 22, and a transmission chain 25 wound around the transmission wheel 24. The lifting drive member 23 is used to drive the second column 22 to move up and down. One end of the transmission chain 25 is fixedly arranged, and the other end of the transmission chain 25 is connected to the beam assembly 40.

[0079] The lifting drive member 23 is a power component that can output linear motion. The transmission wheel 24 can rotate and is installed on the second column 22. The motion output end of the lifting drive member 23 is connected to the second column 22 and moves up and down. One end of the transmission chain 25 is fixed, and the other end of the transmission chain 25 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 at the same time. Since one end of the transmission chain 25 remains stationary, the other end of the transmission chain 25 (the crossbeam assembly 40) moves with the up and down movement of the transmission wheel 24. In addition, the displacement of the crossbeam assembly 40 in the vertical direction is twice the displacement of the transmission wheel 24 in the vertical direction. Specifically, when the lifting drive member 23 is working, the second column 22 moves a distance L relative to the first column 21, and accordingly, 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, when the length of the first column 21 is shorter, a larger vertical stroke of the beam assembly 40 can still be achieved without setting the first column 21 longer.

[0080] Through the cooperation of the transmission wheel 24 and the transmission chain 25, the crossbeam assembly 40 has a large moving stroke. At the same time, the length of the first column 21 is short, which is convenient for production and transportation.

[0081] In some embodiments, there are two transmission wheels 24 , which are respectively disposed on opposite sides of the second column 22 . Correspondingly, there are also two transmission chains 25 , and the crossbeam assembly 40 is pulled up and down by the two transmission chains 25 .

[0082] In some embodiments, see Figure 3 The second column 22 is frame-shaped and is sleeved on the outside of the first column 21. The lifting drive member 23 is fixed to the first column 21, and correspondingly, the lifting drive member 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.

[0083] In some embodiments of the present invention, see Figures 6 to 8 The second column 22 includes two spaced-apart vertical plates 221 and a connecting plate 222 connecting the two vertical plates 221. The two vertical plates 221 are respectively arranged on opposite sides of the first column 21. The crossbeam assembly 40 is fixed to the transmission chain 25 through a mounting frame 26. A guide wheel 263 is arranged between the mounting frame 26 and the vertical plates 221.

[0084] The second column 22 includes two vertical plates 221 and a connecting plate 222. The vertical plates 221 are arranged vertically, and the two vertical plates 221 can be connected into a whole through the connecting plate 222. The crossbeam assembly 40 is fixed to the transmission chain 25 through the mounting frame 26, which can be understood as the crossbeam assembly 40 is fixed to the mounting frame 26, and the mounting frame 26 is fixed to one end of the transmission chain 25. A guide wheel 263 is arranged between the mounting frame 26 and the vertical plate 221, and the guide wheel 263 can be arranged on the mounting frame 26 or the vertical plate 221, so that the mounting frame 26 can move stably relative to the vertical plate 221.

[0085] By configuring the second column 22 to include two vertical plates 221 and a connecting plate 222, the two opposite sides of the first column 21 are respectively slidably matched with the two vertical plates 221, thereby improving the stability of the second column 22 when it moves up and down. By configuring a guide wheel 263 between the mounting frame 26 and the vertical plates 221, the stability of the crossbeam assembly 40 when it moves up and down can be improved.

[0086] In some embodiments, the connecting plates 222 are vertically arranged. When the number of the connecting plates 222 is two, the two connecting plates 222 and the two vertical plates 221 can be connected to form a structure with a frame-shaped cross-section.

[0087] In some embodiments, the connecting plate 222 is horizontally disposed, 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 .

[0088] In some embodiments, the second column 22 also includes a cover structure, which is covered on the top of the two vertical plates 221. The cover structure can shield the transmission wheel 24 and the transmission chain 25 structure to prevent foreign objects from falling into the transmission wheel 24 and the transmission chain 25, and also has a certain dust-proof effect.

[0089] In some embodiments of the present invention, see Figure 7 and Figure 8 The vertical 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 vertical 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.

[0090] In some embodiments of the present invention, the mounting frame 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 arranged 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 is provided with a slide groove 2213 extending in a vertical direction, and the radial sides of the guide wheel 263 between the first mounting plate 261 and the first side wall portion 2211 are clamped in the slide groove 2213.

[0091] The bending connection between the first side wall portion 2211 and the second side wall portion 2212 refers to the formation of an angle between the first side wall portion 2211 and the second side wall portion 2212, 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 surface of the first side wall portion 2211 and the second side wall portion 2212), thereby forming a guide for the movement of the second column 22. An annular groove 2631 can be provided in the circumference of the guide wheel 263 between the first mounting plate 261 and the first side wall 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.

[0092] The cooperation between the limiting angle formed by the vertical plate 221 and the limiting portion 211 on the first column 21 makes the second 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 portion 2211 and between the second mounting plate 262 and the second side wall portion 2212, the vertical movement of the mounting frame 26 relative to the second column 22 is made more stable, and the sliding friction between the mounting frame 26 and the second column 22 is converted into rolling friction, so that the movement of the mounting frame 26 and the crossbeam assembly 40 is smoother.

[0093] In some embodiments, the second side wall portions 2212 are connected to opposite sides of the vertical plate 221, so that the second column 22 has four second side wall portions 2212, and accordingly, the four aforementioned limiting angles are formed. The number of limiting portions 211 is the same as the number of limiting angles, and the number of limiting portions 211 is also four. The four corner positions of the second column 22 are all guided by the limiting portions 211 of the first column 21, so that the up and down movement of the second column 22 can be more stable.

[0094] Optionally, four corners of the top plate of the first column 21 extend to form four limiting portions 211 respectively, corresponding to the four limiting corners one by one.

[0095] 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-shaped frame. In this way, the mounting frame 26 is more stably matched with the second column 22, and there are guiding matching structures between the three sides of the second column 22.

[0096] In some embodiments, the guide wheel 263 is mounted on the mounting frame 26, and the guide wheel 263 can rotate relative to the mounting frame 26. Alternatively, the guide wheel 263 is mounted on the second column 22, and the guide wheel 263 can rotate relative to the second column 22.

[0097] In some embodiments, a plurality of guide wheels 263 are disposed between a first mounting plate 261 and the first side wall portion 2211, and a plurality of guide wheels 263 are disposed between the second mounting plate 262 and the second side wall 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 is.

[0098] In some embodiments of the present invention, see Fig. 9 and Fig.12 The beam assembly 40 includes a first beam 41, a second beam 42 rotatably connected to the first beam 41, a first elastic member 451 connected at both ends to the first beam 41 and the second beam 42 respectively, a first locking assembly 43 and a second locking assembly 44. The beam assembly 40 has a use state and a folded state. The first locking assembly 43 is used to lock the beam assembly 40 in the use state, and the second locking assembly 44 is used to lock the beam assembly 40 in the folded state.

[0099] The second cross beam 42 is rotatably connected to the first cross beam 41. The first cross beam 41 and the second cross beam 42 are arranged in a straight line so that when the cross beam assembly 40 is fully unfolded ( Fig. 9 The state is called the use state, and when the first crossbeam 41 and the second crossbeam 42 are folded to form an angle or folded to overlap, the state is called the folded state. During the rotation of the second crossbeam 42 relative to the first crossbeam 41, the first elastic member 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.

[0100] The second crossbeam 42 can rotate relative to the first crossbeam 41, so that the crossbeam assembly 40 can be folded and stored, which is convenient for the production, transportation and storage of the crossbeam assembly 40. Through the arrangement of the first locking assembly 43 and the second locking assembly 44, the crossbeam assembly 40 can be stably maintained in the use state or the folded state.

[0101] In some embodiments, the first elastic member 451 is a gas spring or a hydraulic spring, which provides sufficient auxiliary force for the folding, storage and unfolding of the second cross beam 42 .

[0102] In some embodiments, see Figures 9 to 14 The first locking assembly 43 and the second locking assembly 44 are respectively disposed on opposite sides of the beam assembly 40 to prevent interference between the first locking assembly 43 and the second locking assembly 44. For example, the first locking assembly 43 is disposed on the upper side of the beam assembly 40, and the second locking assembly 44 is disposed on the lower side of the beam assembly 40.

[0103] In some embodiments of the present invention, see Fig. 9 A gyroscope 452 is disposed on the first beam 41 , and the gyroscope 452 can detect the placement angle of the beam assembly 40 .

[0104] Optionally, there are two gyroscopes 452 , which are respectively disposed on opposite sides of the column assembly 20 . The two gyroscopes 452 are symmetrically disposed, thereby making the detection of the beam assembly 40 more accurate.

[0105] Optionally, there are two second beams 42 , which are rotatably connected to two ends of the first beam 41 , respectively, and a shooting camera 50 is fixed to one end of the second beam 42 away from the first beam 41 .

[0106] In some embodiments, see Figures 9 to 11 The first locking assembly 43 includes a first locking seat 431 fixed to the first cross beam 41, a second locking seat 432 fixed to the second cross beam 42, a hinge shaft 433, two pressing rods 434 hinged to each other through the hinge shaft 433, and a second elastic member connected to the two pressing rods 434 at both ends, one end of the pressing rod 434 has a first clamping portion 4341, the second locking seat 432 has a second clamping portion 4321 respectively clamped with the two first clamping portions 4341, and the other end of the pressing rod 434 has a first button portion 4342 for pressing.

[0107] The first lock seat 431 and the second lock seat 432 are fixed to the first cross beam 41 and the second cross beam 42 respectively, the hinge shaft 433 is arranged on the first lock seat 431, and the two pressing rods 434 are hinged to each other through the hinge shaft 433. One end of the pressing rod 434 has a first clamping portion 4341, and the first clamping portion 4341 is used to clamp with the second clamping portion 4321 of the second lock seat 432, and the other end of the pressing rod 434 has a first button portion 4342, and the first button portion 4342 is used for pressing. Specifically, when the cross beam assembly 40 is in use, the first clamping portion 4341 and the second clamping portion 4321 are clamped to each other, so that the second cross beam 42 is located in the length extension direction of the first cross beam 41. When the beam assembly 40 needs to be stored, two fingers press the two first button portions 4342 at the same time to separate the two first clamping portions 4341 from the second clamping portions 4321 , and then rotate the second beam 42 to the folded state of the beam assembly 40 .

[0108] By providing two mutually hinged pressing rods 434, the first clamping portion 4341 on the pressing rod 434 can be clamped to the second clamping portion 4321 of the second lock seat 432, or separated from the second clamping portion 4321, thereby realizing the locking and unlocking of the beam assembly 40 when in use.

[0109] In some embodiments, see Fig.10 and Fig.11 The first lock seat 431 is provided with first button holes 4311 on opposite sides thereof, and the first button parts 4342 are located in the corresponding first button holes 4311, so that the first button parts 4342 are exposed to facilitate pressing by the user. Pressing the two first button parts 4342 at the same time can unlock the beam assembly 40 in use.

[0110] In some embodiments, see Fig.11 The same end of the two pressing rods 434 extends toward each other to form a first hook-shaped clamping portion 4341, and the second lock seat 432 extends toward the first lock seat 431 to form a second clamping portion 4321. The opposite sides of the second clamping portion 4321 are concave to form a slot, and the second clamping portion 4321 is arrow-shaped, so that the two first clamping portions 4341 can be more smoothly inserted into the inside of the slot along the two sides of the clamp head-shaped structure.

[0111] In some embodiments, see Fig.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 correspondingly in the vertical direction, which will not affect the folding and unfolding of the second crossbeam 42.

[0112] In some embodiments, the second elastic member is a torsion spring, and the second elastic member is sleeved on the hinge shaft 433 , which can provide a pressing force for the clamping of the first clamping portion 4341 and the second clamping portion 4321 .

[0113] In some embodiments of the present invention, see Figure 12 to Figure 14 The second locking assembly 44 includes a third lock seat 441 fixed to the first beam 41, a fourth lock seat 442 fixed to the second beam 42, a sliding structure 443 slidably arranged on the third lock seat 441, and a third elastic member 444 whose two ends are respectively connected to the sliding structure 443 and the third lock seat 441. The third lock seat 441 and the fourth lock seat 442 are hinged to each other, the sliding structure 443 has a third clamping portion 4431 and a second button portion 4432 for pressing, and the fourth lock seat 442 has a fourth clamping portion 4421 clamped with the third clamping portion 4431; when the third clamping portion 4431 and the fourth clamping portion 4421 are clamped, the first beam 41 and the second beam 42 are perpendicular to each other.

[0114] The third lock seat 441 and the fourth lock seat 442 are fixed to the first beam 41 and the second beam 42, respectively, and the sliding structure 443 can slide relative to the third lock seat 441. When the beam assembly 40 is in use, the third clamping portion 4431 and the fourth clamping portion 4421 are separated from each other. When the beam assembly 40 needs to be stored, the first locking assembly 43 is unlocked, and then the second beam 42 is rotated to be perpendicular to the first beam 41, and the third clamping portion 4431 and the fourth clamping portion 4421 are clamped together. When the beam assembly 40 needs to be transformed into a use state, the second button portion 4432 is pressed, the third elastic member 444 is compressed, the third clamping portion 4431 and the fourth clamping portion 4421 are separated from each other, and then the second beam 42 is rotated to transform the beam assembly 40 into a use state, and the first clamping portion 4341 and the second clamping portion 4321 are clamped together.

[0115] By providing a sliding structure 443 that can slide relative to the third locking seat 441, the third clamping portion 4431 and the fourth clamping portion 4421 can be mutually clamped or separated, thereby achieving locking and unlocking of the beam assembly 40 in the folded state.

[0116] In some embodiments, see Fig.14 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 arranged inside the lock seat body 4411. The lock seat cover 4412 is provided with a second button hole 4413. The second button part 4432 extends into the second button hole 4413, which is convenient for the user to press the second button part 4432.

[0117] In some embodiments, see Fig.14 The moving direction of the sliding structure 443 is the vertical direction. When the sliding structure 443 is moved in the vertical direction, the third clamping portion 4431 and the fourth clamping portion 4421 can be mutually engaged or disengaged, and at the same time, the unfolding and folding of the beam assembly 40 are not affected.

[0118] In some embodiments of the present invention, see Fig. 9 and Fig.12 There are two second beams 42, which are rotatably connected to the two ends of the first beam 41, and a camera 50 is fixed to one end of the second beam 42 away from the first beam 41. It can be understood that both ends of the beam assembly 40 can be folded, so that the length of the beam assembly 40 is shortened, and the beam assembly 40 is a symmetrical structure, and the force is relatively balanced even in the folded state.

[0119] Optionally, the first cross beam 41 is symmetrically arranged relative to the column assembly 20 , and the two second cross beams 42 are also symmetrically arranged relative to the column assembly 20 , so as to facilitate adjustment of the position and angle of the shooting camera 50 .

[0120] In other embodiments, the number of the second cross beam 42 may also be one, which is disposed at one end of the first cross beam 41 .

[0121] In some embodiments of the present invention, see Fig.12 and Fig.15 The hanging assembly 460 includes a first hanging structure 46 that is clamped to the beam assembly 40 and can slide relative to the beam assembly 40. The first hanging structure 46 includes a hanging plate 461 and a sliding clamping structure 463 fixed to the hanging plate 461. The hanging plate 461 is provided with a hanging hole 4611 for hanging the calibration component.

[0122] The first hanging structure 46 is clamped on the beam assembly 40 when in use, and can slide relative to the beam assembly 40. The sliding direction of the first hanging structure 46 is the length direction of the beam assembly 40. Therefore, the horizontal position of the first hanging structure 46 can be changed, and the horizontal position of the calibration member hung on the first hanging structure 46 can also be changed. The first hanging structure 46 includes a hanging plate 461 and a sliding clamping structure 463. The sliding clamping structure 463 enables the first hanging structure 46 to slide and be clamped on the beam assembly 40, and the hanging plate 461 is used to hang the calibration member. Specifically, the back of the calibration member is generally convexly provided with a hanging protrusion, and the hanging protrusion is inserted into the hanging hole 4611, so that the calibration member can be stably hung on the hanging plate 461.

[0123] By providing a sliding card structure 463 on the first hanging structure 46, the first hanging structure 46 can slide relative to the beam assembly 40, thereby adjusting the horizontal position of the first hanging structure 46. The first hanging structure 46 can also be stably carded on the beam assembly 40, and the first hanging structure 46 can also be removed from the beam assembly 40 as needed.

[0124] In some embodiments, see Fig.15 The hanging hole 4611 is arranged on the top side of the hanging plate 461 and is formed by the top side of the hanging plate 461 being recessed downward. The hanging protrusion has a neck with a smaller diameter than other positions, and the neck of the hanging protrusion is inserted into the hanging hole 4611.

[0125] In some embodiments, see Fig.15 There are multiple hanging holes 4611, and the multiple hanging holes 4611 are arranged in sequence along the length direction of the beam assembly 40, which can make the calibration part more stable when hung on the hanging plate 461.

[0126] In some embodiments of the present invention, see Fig.12 and Fig.17The hanging assembly 460 also includes a supporting structure 48, one end of the supporting structure 48 is rotatably connected to the beam assembly 40, and the other end of the supporting structure 48 has a supporting protrusion 481 for supporting the calibration piece. A first clamping structure 411 is fixed on the beam assembly 40, and a second clamping structure 482 is arranged on the supporting structure 48. The first clamping structure 411 and the second clamping structure 482 are clamped with each other, so that the supporting structure 48 is arranged close to the beam assembly 40.

[0127] The support structure 48 is used to support the bottom of the calibration piece. When the calibration piece is large or heavy, the support of the calibration piece by the support structure 48 can reduce the shaking of the calibration piece. The support structure 48 has a use state and a storage state. When the support structure 48 rotates relative to the crossbeam assembly 40 until the first clamping structure 411 and the second clamping structure 482 are mutually clamped, the support structure 48 is close to the crossbeam assembly 40, and the support structure 48 is in the storage state. When the support structure 48 rotates 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 piece, and the support structure 48 is in the use state.

[0128] The support structure 48 can support the bottom plate of the calibration part, making the calibration part more stable and reducing the shaking of the calibration part. In addition, the support structure 48 can be rotated to the storage state and connected with the crossbeam assembly 40, that is, when the support structure 48 is not needed, it can be rotated and stored without affecting other testing work of the calibration equipment.

[0129] In some embodiments, see Fig.12 and Fig.17 The support protrusion 481 can support the bottom of the calibration piece and can also be held by the user. When the support structure 48 needs to be rotated, the user can hold the support protrusion 481 to rotate the support structure 48.

[0130] Optionally, the supporting protrusion 481 is a cylindrical structure, a rectangular parallelepiped structure, etc.

[0131] In some embodiments, an alignment groove is provided on the surface of the supporting protrusion 481. When the supporting structure 48 is in use, the bottom edge of the calibration piece is inserted into the alignment groove, so that the calibration piece can be kept in a vertical state to prevent the calibration piece from having an unexpected pitch posture.

[0132] In some embodiments, one of the first clamping structure 411 and the second clamping structure 482 is a protruding structure, and the other is a recessed structure. Figure 5 The first clamping structure 411 is a recessed structure, and the second clamping structure 482 is a raised structure.

[0133] Optionally, a marble is provided on the inner wall of the recessed structure, and the top size of the raised structure is larger than its root size. When the raised structure gradually enters the recessed structure, the marble is pressed. After the raised structure is in place, the size of the raised structure opposite to the marble is smaller than its maximum size. The marble presses the raised structure so that the raised structure is clamped in the recessed structure.

[0134] Optionally, the protruding structure may be spherical or disc-shaped.

[0135] In some embodiments of the present invention, see Fig.12 and Fig.16 The hanging assembly 460 also includes a second hanging structure 47 which is clamped to the beam assembly 40 and can slide relative to the beam assembly 40. The number of the second hanging structures 47 is two and they are respectively arranged on the opposite sides of the first hanging structure 46. The second hanging structure 47 includes a limiting plate 471 and a sliding clamping structure 463 fixed to the limiting plate 471. The limiting plate 471 is provided with a limiting groove 4711 on the side facing the calibration piece for clamping the side wall of the calibration piece.

[0136] The second hanging structure 47 is used to limit the side of the calibration piece. The second hanging structure 47 can be clamped on the beam assembly 40, or it can slide relative to the beam assembly 40, that is, the second hanging structure 47 can adjust its position on the beam assembly 40. The second hanging structure 47 includes a limiting plate 471 and a sliding clamping structure 463. The setting of the sliding clamping structure 463 enables the entire second hanging structure 47 to be slidably clamped on the beam assembly 40. The limiting plate 471 is provided with a limiting groove 4711. When the second hanging structure 47 is used, the side edge of the calibration piece extends into the limiting groove 4711.

[0137] When the calibration object to be hung is large, it is easy to shake. Hanging the calibration object only by the first hanging structure 46 is not stable. The calibration object can be more stable by limiting the left and right sides of the calibration object by two second hanging structures 47 respectively.

[0138] In some embodiments, the limiting groove 4711 is extended 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, so that the limiting plate 471 can be clamped at any position of the side wall of the calibration component.

[0139] In some embodiments, the first hanging structure 46 is disposed in the middle of the beam assembly 40, and the two second hanging structures 47 are respectively disposed on opposite sides of the first hanging structure 46, so that the calibration piece is placed symmetrically.

[0140] In some embodiments of the present invention, the sliding clamping structure 463 includes a fixed seat 4633, a clamping piece 4632, a clamping elastic piece 4634 and a lever 4636. The fixed seat 4633 is fixed to the hanging plate 461 or the limiting plate 471. The two ends of the clamping elastic piece 4634 are respectively connected to the fixed seat 4633 and the clamping piece 4632. The clamping piece 4632 is clamped to the opposite sides of the beam assembly 40 through the clamping elastic piece 4634. The lever 4636 is hinged to the hanging plate 461 or the limiting plate 471, and one end of the lever 4636 has a pushing portion 46361. The pushing portion 46361 is used to push the clamping piece 4632 to separate the clamping piece 4632 from the beam assembly 40.

[0141] For the convenience of explanation, the hanging plate 461 and the limiting plate 471 can be collectively referred to as a fixed structure, and the sliding clamping structure 463 is fixed to the fixed structure, specifically, the fixing seat 4633 is fixed to the fixed structure. In the first hanging structure 46, the fixing seat 4633 is fixed to the hanging plate 461; in the second hanging structure 47, the fixing seat 4633 is fixed to the limiting plate 471. When the lever 4636 is toggled, the pushing portion 46361 on the lever 4636 pushes the pressing member 4632, so that the pressing member 4632 and the beam assembly 40 are separated from each other, the hanging structure is unlocked from the beam assembly 40, and the first hanging structure 46 and the second hanging structure 47 are pushed to a predetermined position, and then the lever 4636 is restored to the initial position.

[0142] The pressing member 4632 is pressed against the cross beam assembly 40 by the setting of the pressing elastic member 4634, and cooperates with the scale 4631 to realize the hook structure being connected to the cross beam assembly 40. In addition, the compression amount of the pressing elastic member 4634 can be controlled by the movement of the lever 4636, so that the locking and unlocking of the hook structure can be quickly controlled.

[0143] In some embodiments, see Fig.15 and Fig.16 The clamping member 4632 has a friction surface on one side for clamping the cross beam assembly 40 . The static friction between the friction surface and the cross beam assembly 40 is relatively large, so that the first hanging structure 46 and the second hanging structure 47 can be more stably clamped on the cross beam assembly 40 .

[0144] Optionally, the friction surface is the surface of the pressing member 4632, which may be roughened and have a relatively large surface roughness.

[0145] Optionally, the friction surface is the surface of a friction plate 4637, the friction plate 4637 is fixed on the pressing member 4632, and the friction plate 4637 is used to press on the cross beam assembly 40. The surface of the friction plate 4637 is rough, and the static friction between the friction plate 4637 and the cross beam assembly 40 is relatively large.

[0146] In some embodiments, see Fig.15and Fig.16 The push part 46361 is disposed at one end of the lever 4636, and the push part 46361 has two push claws 46362 disposed at intervals, and the two push claws 46362 are disposed at intervals in a length direction parallel to the cross beam assembly 40. In this way, the push part 46361 has a larger size in the length direction of the cross beam assembly 40, and the lever 4636 can push and compress the elastic member 4634 when swinging leftward or rightward. Moreover, when the external force is lost, the lever 4636 will automatically return to the normal position and clamp on the cross beam assembly 40 to prevent the hanging structure from falling off the cross beam assembly 40.

[0147] In some embodiments, see Fig.15 and Fig.16 When the lever 4636 is vertically arranged, the first hanging structure 46 and the second hanging structure 47 are in a locked state and are fixed to the cross beam assembly 40; when the lever 4636 is tilted, the first hanging structure 46 and the second hanging structure 47 are in an unlocked state and can slide relative to the cross beam assembly 40. In this way, it is convenient for the user to identify the current state of the hanging structure.

[0148] In some embodiments, see Fig.15 and Fig.16 The sliding clamping structure 463 further includes a guide rod 4635, one end of which is fixed to the pressing member 4632, the other end of which is inserted into the fixing seat 4633, and the pressing elastic member 4634 is sleeved on the guide rod 4635. The setting of the guide rod 4635 can make the unlocking and locking process (up and down movement) of the pressing member 4632 more stable, and also provide an installation position for the pressing elastic member 4634.

[0149] In some embodiments, see Fig.15 and Fig.16 The sliding clamping structure 463 also includes a ruler 4631, which has scale lines, and the beam assembly 40 has corresponding scales. The setting of the ruler 4631 is convenient for the user to read and obtain the current position of the hanging structure. In the first hanging structure 46, the ruler 4631 is fixed on the hanging plate 461; in the second hanging structure 47, the ruler 4631 is fixed on the limit plate 471.

[0150] In some embodiments of the present invention, see Fig.12 The crossbeam assembly 40 has a slide rail 49 , and the first hanging structure 46 and the second hanging structure 47 are both installed on the slide rail 49 , and the first hanging structure 46 and the second hanging structure 47 are both slidably disposed on the slide rail 49 .

[0151] In some embodiments of the present invention, see Figure 1The vehicle measurement device further includes a flat panel mounting structure 60 fixed to the first column. The flat panel mounting structure 60 is used to mount a fixed flat panel, which can be wirelessly connected to the vehicle-mounted system to facilitate real-time adjustment of vehicle parameters during the detection process. The flat panel mounting structure 60 can clamp the flat panel, place the flat panel, support the flat panel, etc. The specific structure of the flat panel mounting structure 60 is not limited here.

[0152] In some embodiments, the tablet mounting structure 60 is an inclined plate placed obliquely, and the bottom of the inclined plate has an edge stopper for stopping the bottom of the tablet.

[0153] In some embodiments of the present invention, see Figure 1 and Figure 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 .

[0154] The control module can be a data processing system of the vehicle measurement equipment, and the control module is connected with the key structure 80 and the display device 7 0 , the base assembly 10 and the column assembly 20 are all electrically connected. The button structure 80 can control the movement of the base assembly 10 and the column assembly 20. For example, the base assembly 10 can be controlled to drive the column assembly 20 to move horizontally in the first direction and the second direction, drive the column assembly 20 to rotate, drive the crossbeam assembly 40 to move up and down relative to the first column 21, etc. The button structure 80 can also control the start and stop of the vehicle measurement equipment. The display device is used to display the parameters detected by the measurement equipment, the set parameters, etc.

[0155] Automatic control of the vehicle measuring device can be achieved through the control module, the display device 70, the key structure 80, etc., making the vehicle measuring device easier to operate.

[0156] In some embodiments, the control module may be disposed inside the first column 21. The control module may be a main board having a switch structure disposed thereon corresponding to the buttons of the key structure 80 one by one.

[0157] In some embodiments, the display device 70 is a display, a display panel, or the like.

[0158] In some embodiments, the key structure 80 is a physical mechanical key switch or a rotary switch, or a touch-type capacitive switch.

[0159] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
