Description

Technical Field

[0001] The embodiments of the present invention relate to the field of vehicle calibration, and particularly to a vehicle measurement device. Background Art

[0002] As an indispensable means of transportation in people's lives, automobiles are used in many fields, and the requirements for their safety performance are also constantly increasing. Generally, after a vehicle has been used for a period of time, it needs to be sent to a repair shop for maintenance. For example, the wheels are calibrated through four-wheel alignment; or the ADAS is calibrated to ensure that sensors such as cameras or radars inside the vehicle accurately obtain road conditions.

[0003] Currently, for vehicle measurement devices on the market, such as ADAS (Advanced Driver Assistant Systems) calibration devices, when calibrating the ADAS of an automobile, it is necessary to ensure that the measurement device is straight and symmetrical with the vehicle body. Usually, the position of the base of the vehicle measurement device relative to the ground is adjusted, and during the adjustment process, workers need to bend down frequently, which brings inconvenience.

[0096] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0097] Embodiment 1

[0098] Such as Figures 1 - 3As shown, a vehicle measurement device 900 provided by one embodiment of the present invention includes a base module 100, a column module 200, a crossbeam module 300, and a camera assembly 400. The column module 200 is installed on the base module 100, the crossbeam module 300 is installed on the column module 200, and the camera assembly 400 is installed on the crossbeam module 300. The column module 200 is used to support the crossbeam module 300 and can be used to adjust the height of the crossbeam module 300 from the ground. The crossbeam module 300 can be used to support calibration elements. The camera assembly 400 is used to capture wheel information of the vehicle. In this way, the user can capture the wheel information of the vehicle through the camera assembly 400 to calibrate the wheels of the vehicle to achieve four-wheel alignment. At the same time, the crossbeam module 300 can also be used to support calibration elements to calibrate sensors on the vehicle.

[0099] Please refer to Figure 4 , in some embodiments, the base module 100 includes a base 111, a plurality of universal wheels 112, and a plurality of foot cups 113. The plurality of universal wheels 112 and the plurality of foot cups 113 are both installed on the base 111. The universal wheels 112 can make the vehicle measurement device 900 easy to move. The foot cups 113 can be used to stabilize the base module 100 at a specific location, and the foot cups 113 can also be used to adjust the height of the base module 100. The base 111 is used to install the column module 200. In this embodiment, the base 111 has four outwardly extending mounting portions (not labeled). The number of universal wheels 112 is four, and each mounting portion corresponds to and mounts one universal wheel. The number of foot cups 113 is three. The three foot cups are distributed in a triangular shape at three positions of the base 111. By adjusting the foot cups, the angle of the column module relative to the ground can be adjusted, and thus the pitch angle of the measuring module can be adjusted. Among them, the foot cup 113 includes a support block 1131, a connecting rod 1132, and a cap portion 1133. The outer surface of the connecting rod 1132 has threads. One end of the connecting rod 1132 is threadedly connected to the cap portion 1133, and the other end of the connecting rod is threadedly connected to the support block 1131, and the support block 1131 is used to abut against the ground. In this way, turning the nut portion 1133 can achieve the distance between the base 111 and the ground to adjust the overall position and overall attitude of the vehicle measurement device 900.

[0100] Such as Figures 5 - 7As shown, in some embodiments, the column module 200 includes a fixed column 210, a movable column assembly 220, and a driving assembly 230. The fixed column 210 is connected to the base 111. The movable column assembly 220 is movably mounted on the fixed column 210, and the movable column assembly 220 is connected to the driving assembly 230. The driving assembly can be disposed within the fixed column. In some implementation manners, the driving assembly 230 is configured to only drive the movable column assembly 220 to rise or fall relative to the fixed column 210, and the crossbeam module 300 rises or falls synchronously with the movable column 220. In this way, the rising or falling of the crossbeam module 300 can be controlled by the driving assembly 230, so that the crossbeam module 300 can be adjusted to different ground clearances, enabling the vehicle measuring device 900 to be applicable to more scenarios. For example, the same vehicle measuring device 900 can be used to calibrate vehicles of different models. In this application, "rise" or "fall" refers to the vertical movement relative to a reference object, and this vertical direction is substantially the same as the length direction of the column module. For example, the vertical movement of the movable column assembly 220 relative to the fixed column 210, the vertical movement of the crossbeam module 300 relative to the movable column assembly 220, etc. In other implementation manners, while the driving assembly is configured to drive the movable column assembly 220 to rise or fall relative to the fixed column 210, the driving assembly 230 is further configured to drive the crossbeam module 300 to rise or fall relative to the movable column assembly 220. That is, the movements of the movable column assembly 220 and the crossbeam module 300 are not synchronous. The movable column assembly 220 and the crossbeam module 300 can move in the same direction or in opposite directions. The moving speed of the movable column assembly 220 and the moving speed of the crossbeam module 300 can be the same or different. The driving mechanism for driving the movable column assembly 220 to move relative to the fixed column 210 in the driving assembly can be associated with the driving mechanism for driving the crossbeam module 300 to move relative to the movable column assembly 220, or the two driving mechanisms are independent of each other. This document mainly introduces some implementation manners in which the driving assembly drives the movable column assembly 210 and the crossbeam module 300 to move in the same direction, and the moving speed of the crossbeam module 300 is faster than that of the movable column assembly 210. Other driving manners of the driving assembly should also be included within the scope of this application. By the movement of the movable column assembly 220 relative to the fixed column 210 and the movement of the crossbeam module 300 relative to the movable column assembly 210, while reducing the volume of the column module, the movement range of the crossbeam module is ensured, the usage range is expanded, and it can meet the requirements for measuring the wheel alignment function at different heights, as well as the requirements for calibrating the auxiliary system at different heights.

[0101] Please refer to Figure 5 and Figure 6, the fixed column 210 includes a column shell 211, a fixed support 212, a limit seat 213 and a sliding assembly 214. The fixed support 212, the limit seat 213 and the sliding assembly 214 are all installed in the column shell 211, and the fixed support 212 and the limit seat 213 are respectively located at both ends of the column shell 211. The fixed support 212 is used to connect with the drive assembly 230, the limit seat 213 is used to limit the moving column assembly 220, and the sliding assembly 214 is used to connect with the moving column assembly 220.

[0102] Wherein, the column shell 211 includes a base 2111, a first column shell 2112 and a second column shell 2113. The base 2111 is used for fixedly installing on the base 111 in the base module 100. The fixed support 212 is arranged on the base 2111. The first column shell 2112 is installed on the base 2111 and forms a receiving cavity (not marked). The second column shell 2113 is detachably connected to the first column shell 2112 to enclose the receiving cavity. When the second column shell 2113 is installed on the base 2111, there is a gap between the second column shell 2113 and the first column shell 2111. Specifically, each of the first column shell 2111 and the second column shell 2113 includes a main board and two side boards. The two side boards are arranged on both sides of the main board and are oppositely arranged, so that the cross-sections of the first column shell 2111 and the second column shell 2113 are generally concave. The main boards of the first column shell 2111 and the second column shell 2113 are opposite to each other. There is no connection and coupling between the side boards of the first column shell 2111 and the second column shell 2113 on the same side, but there is a gap. Similarly, there is also a gap between the side boards on the other side of the first column shell 2111 and the second column shell 2113. The gaps between the side boards on both sides are generally in the vertical direction and are the same as the moving direction of the cross beam module 300. Through the gap formed by enclosing the first column shell 2112 and the second column shell 2113, the cross beam module can slide freely on the fixed column, that is, it ensures that the lifting plate for installing the cross beam module below can move relative to the fixed column. The fixed support 212 is detachably installed on the base 2111 and is received in the receiving cavity. The limit seat 213 is installed at one end of the first column shell 2112 away from the base 2111. The sliding assembly 214 is slidably installed in the first column shell 2112. In this embodiment, two symmetrically arranged fixing members 2114 are provided on the first column shell 2112 near the base 2111.

[0103] The sliding component 214 includes a guide rail bar 2141 and a sliding block 2142. The guide rail bar 2141 is installed on the inner wall of the first column shell 2112 and is arranged along the axial direction (length direction) of the first column shell 2112. The sliding block 2142 is cooperatively installed with the guide rail bar 2141, and the sliding block 2142 is connected to the moving column assembly 220.

[0104] Please combine Figure 7 with Figure 8 , in some embodiments, the fixed column 210 is further provided with a plurality of rollers 215. The plurality of rollers 215 are movably installed at the side end of the limit seat 213. A part of the plurality of rollers 215 extends out of the edge of the limit seat 213 and abuts against the moving column assembly 220. The rollers 215 are used to reduce the frictional resistance between the moving column assembly 220 and the fixed column 210.

[0105] As Figure 9 shown, the moving column assembly 220 includes a column body 221, a traction member 222 and a lifting plate 223. The traction member 222 is installed on the column body 221, and one end of the traction member 222 is connected to the first column shell 2112, and the other end of the traction member 222 is connected to the lifting plate 223. The lifting plate 223 is connected to the cross beam module 300. In this embodiment, the traction member 222 is a chain. One end of the chain is fixedly connected to the fixing member 2114 on the first column shell 2112, and the other end of the chain passes through the top of the column body 221 and is connected to the lifting plate 223. It should be understood that the traction member 222 can be other structures in addition to a chain, such as a rope or a steel wire rope, etc., as long as it can realize the lifting or lowering of the lifting plate 223.

[0106] Thus, when the driving component 230 drives the moving column component 220 to rise or fall relative to the fixed column 210, under the action of the traction member, the lifting plate 223 will move relative to the column body 221 to drive the crossbeam module 300 to rise or fall. Here, the crossbeam module 300 is pulled by the traction member 222 and can move twice the stroke relative to the column body 221, that is, the moving speed of the crossbeam module 300 pulled by the traction member 222 is twice the moving speed of the column body 221. It can be known that within the same time, the moving distance of the crossbeam module 300 is twice the moving distance of the column body 221. Furthermore, the moving range of the crossbeam is expanded, and the crossbeam module can be adjusted to almost any height of the column module. For example, when the moving vertical column rises to the highest height, the height of the entire column module can be 2.5 meters. In this case, the height adjustment range of the crossbeam module can be [0.3 meters, 2.1 meters]. Thus, it can be ensured that the height of the crossbeam module is suitable for both the wheel positioning measurement function and the calibration function of the assisted driving system. Here, the traction member can pull the crossbeam module 300 to move in the same direction as the moving column component 220.

[0107] As Figure 10 shown, the column body 221 includes a first column shell 2211, a second column shell 2212, a top plate 2213, and a bottom plate 2214. The top plate 2213 is connected to one end of the first column shell 2211 and the second shell 2212, and the bottom plate 2214 is connected to the other end of the first column shell 2211 and the second shell 2212. The traction member 222 and the lifting plate 223 are both installed between the first column shell 2211 and the second shell 2212. A plurality of through holes (not labeled) are provided on the top plate 2213, and the traction member 222 is connected to the fixed column 210 and the lifting plate 223 through the through holes. Among them, the first column shell 2211 is provided with an avoidance groove 22111. The avoidance groove and the lifting plate 223 are respectively located on opposite side ends of the first column shell 2211. The column body 221 is movably received in the fixed column 210, that is, the moving stand component can be sleeved in the fixed column 210. The avoidance groove is used to avoid the driving component 230 during the rising or falling process of the column body 221.

[0108] The lifting plate 223 includes a main body plate 2231 and connecting plates 2232 connected to both ends of the main body plate 2231. The main body plate 2231 is connected to the traction member 222, and the connecting plates 2232 are connected to the crossbeam module 300.

[0109] Further, the movable column assembly 220 further includes a rotating member 224. The rotating member 224 is installed on the top plate 2213 of the column body 221. The traction member 222 is partially wound around the rotating member 224. The rotating member 224 is used to reduce the friction between the traction member 222 and the column body 221. In this embodiment, the rotating member 224 is a sprocket, and the sprocket cooperates with the chain, which can make the movable column assembly 220 rise or fall more stably relative to the fixed column 210. Of course, the rotating member 224 can also be other structures, not limited to the sprocket, as long as it can reduce the friction between the traction member 222 and the main body 221, for example, it can be a movable pulley.

[0110] In some embodiments, in order to prevent the rotating member 224 from being directly affected by external dust, etc., the column body 221 further includes a top cover 2215. The top cover 2215 covers the top plate 2213 so that the rotating member 224 is not exposed to the outside. At the same time, the top cover cooperates with the first housing 2211 and the second housing 2212 to protect the traction member 222 from direct external action.

[0111] In some embodiments, the column body 221 is provided with a guiding structure (not labeled). The main body plate 2231 can move directionally through the guiding structure. The guiding structure can be a slider. At this time, a sliding groove is provided on the column body 221, and the slider can slide directionally in the sliding groove. The slider is connected to the main body plate 2231. The guiding structure can also be other structures, for example, it can be a combination of a guiding strip and a guiding block. The guiding strip is fixedly installed on the inner wall of the column body 221, and the guiding block is connected to the main body plate 2231.

[0112] Please combine Figure 9 with Figure 11 , in some embodiments, the movable column assembly 220 further includes a connecting support 225. The connecting support 225 is installed on the top plate 2213, and the connecting support 225 is distributed along the axial direction of the column body 221 and is away from the fixed column 210. The connecting support 225 is used to connect with the driving assembly 230. In this embodiment, the connecting support 225 has a base block 2251 and two symmetrically arranged connecting arm blocks 2252. The base block is connected to the column body 221. The two connecting arm blocks 2252 are respectively connected to both ends of the base block 2251, and through holes (not labeled) are provided on each connecting arm block 2252.

[0113] In some embodiments, the movable column assembly 220 further includes a drag reduction member 226. The drag reduction member 226 is installed on the second housing 2212, and the drag reduction member 226 abuts against the inner wall of the fixed column 210. In this embodiment, the drag reduction member 226 includes a plurality of wheels 2261 and a mounting block 2262 for mounting the plurality of wheels 2261. The mounting block 2262 is fixedly installed on the second housing 2212. When the movable column assembly 220 moves up or down relative to the fixed column 210, the plurality of wheels 2261 will roll-friction with the column housing 211, preventing the movable column assembly 220 and the fixed column 210 from interfering with the up or down movement of the lifting plate 223 due to excessive frictional resistance.

[0114] In some embodiments, the movable column assembly 220 further includes a guiding connecting member 227, as Figure 9 shown. The guiding connecting member 227 is installed on the column body 221, and the guiding connecting member 227 is connected to the sliding block 2142 of the fixed column 210. In this way, driven by the driving assembly 230, the column body 221 will only move axially along the fixed column 210 under the combined action of the guiding connecting member 227 and the sliding block 2142.

[0115] As Figure 12 shown, the driving assembly 230 includes a pusher 231. The pusher 231 includes a push rod 2311 and a main body 2312. The push rod 2311 is movably installed inside the main body 2312, that is, the push rod 2311 can extend and retract relative to the main body 2312. One end of the push rod 2311 away from the main body 2312 passes through the limit seat 213 and is connected to the movable column assembly 220. When the push rod 2311 gradually extends out of the main body 2312, the push rod 2311 will gradually push the movable column assembly 220 out of the fixed column 210, and when the push rod 2311 retracts reversely into the main body 2312, the push rod 2311 will drive the movable column assembly 220 to retract into the fixed column 210. It should be understood that the pusher 231 can be a pneumatic cylinder or a hydraulic cylinder, and of course it can also be other structures. At this time, the push rod 2311 is the push rod of the pneumatic cylinder or the hydraulic cylinder, and the main body 2312 is the cylinder body of the pneumatic cylinder or the hydraulic cylinder.

[0116] Further, the driving assembly 230 further includes a driving motor 232 and a conversion box 233. The output shaft of the driving motor 232 is connected to the conversion box 233. The main body 2312 is connected to the conversion box 233, and the conversion box 233 is connected to the fixed column 210. When the output shaft of the driving motor 232 rotates, the conversion box 233 will drive the push rod 2311 to push the moving column assembly 220 to extend or retract from the fixed column 210. It can be understood that the conversion box 233 is used to convert the rotation of the output shaft of the driving motor 232 into the linear motion of the push rod 2311. In this embodiment, the conversion box 233 is a gear box. A plurality of gears for transmission are provided inside the gear box. The push rod 2311 is a lead screw. The output shaft of the driving motor 232 is connected to a gear of the gear box, and another gear of the gear box is engaged with the lead screw.

[0117] The driving assembly 230 further includes a hinge plate 234. The hinge plate 234 is installed at one end of the conversion box 233 facing the fixed support 212, and the hinge plate 234 is hinged to the fixed support 212. It should be understood that the hinge plate 234 is hinged to the fixed support 212, which can make the hinge plate 234 drive the conversion box 233 to slightly rotate relative to the fixed support 212, so that the pusher 231 can be flexibly adjusted adaptively during use. At the same time, under the limitation of the limit seat 213, the central axis of the pusher 231 will remain parallel to the central axis of the fixed column 210 to prevent the pusher 231 from jamming when pushing the moving column assembly 220.

[0118] In some embodiments, the vehicle measurement device 900 further includes a control system installed on the fixed column 210. The control system is configured to control the drive assembly 230 to drive the movable column assembly 220 to rise or fall relative to the fixed column 210. In this embodiment, the control system includes a power supply, a motor driver, and a switch button. The power supply is connected to the motor driver and the switch button respectively. The motor driver is used to drive and control the operation of the drive motor 232. The switch button is used to control the movable column assembly 220 to rise or fall relative to the fixed column 210. In some embodiments, the control system further includes an emergency control button, which is used to instruct the control system to cut off the power supply or stop outputting control instructions in case of emergency to avoid danger. In some embodiments, the control system further includes a lift button, which is used to receive user operations and transmit the user's lift instructions to the motor driver to control the lift operation of the push rod driven by the driver. The lift button and the emergency control button can be set on the column shell of the fixed column, and their heights can be set to facilitate user operation and improve the user experience.

[0119] With the above structure, under the action of the pusher 231, the movable column assembly 220 can extend or retract into the fixed column 210. If the overall height of the column body 221 is close to the overall height of the fixed column, the overall minimum height of the column module 200 is the height of the fixed column, and the maximum height is close to the sum of the axial lengths of the fixed column 210 and the column body 221, that is, approximately twice the height of the fixed column. Of course, the maximum ground clearance height that the lift plate 223 can rise to is approximately close to the maximum height of the column module 200, and the minimum ground clearance height that the lift plate 223 can descend to is the ground clearance height of the column shell 221 near the base 2111 when the column shell 221 is completely retracted into the fixed column 210. Therefore, the user can adjust the height of the column module 200 as needed to make the crossbeam module 300 have different ground clearance heights, so that the column module 200 can simultaneously meet the height requirements of four-wheel alignment and the Advanced Driving Assistance System (ADAS).

[0120] Such as Figures 13 - 15As shown, the crossbeam module 300 includes a crossbeam 310, the crossbeam 310 includes a left crossbeam portion 312, a connecting portion 314, and a right crossbeam portion 316. One end of the connecting portion 314 is pivotally connected to the left crossbeam portion 312, and the other end of the connecting portion 314 is pivotally connected to the right crossbeam portion 312. The connecting portion 314 is supported by the lifting plate 223. Thus, the crossbeam 310 will have a deployed state and a folded state. When the crossbeam 310 is in the deployed state, both the left crossbeam portion 312 and the right crossbeam portion 316 will rotate to be in a horizontal line with the connecting portion 314. Conversely, when the crossbeam 310 is in the folded state, both the left crossbeam portion 312 and the right crossbeam portion 316 will form an angle with the connecting portion 314, and this angle is greater than 0° and less than or equal to 90°. It can be understood that the calibration element can be directly installed on the crossbeam 310, for example, directly hung on the crossbeam 310 by means of a hook or a magnet. The crossbeam 310 can be used to install the calibration element whether in the deployed state or the folded state. When the crossbeam 310 is in the deployed state, the calibration element can be mounted at different positions on the crossbeam 310 to meet the calibration requirements. When the crossbeam 310 is in the folded state, the left crossbeam portion 312 and the right crossbeam portion 316 can be used together to mount the calibration element.

[0121] Thus, when the vehicle measuring device 900 is not needed, by rotating both the left crossbeam portion 312 and the right crossbeam portion 316 relative to the connecting portion 314, the crossbeam 310 can be in the folded state to reduce the space occupied by the vehicle measuring device 900. Under the action of gravity, both the left crossbeam portion 312 and the right crossbeam portion 316 will naturally droop, and the angle with the connecting portion 314 is close to 90°, which can minimize the space occupied by the vehicle measuring device 900.

[0122] It should be understood that an articulated structure is provided between the left crossbeam portion 312 and the connecting portion 314, and between the right crossbeam portion 316 and the connecting portion 314. The articulated structure can be a combination of a pin shaft and a pin hole. Specifically, the left crossbeam portion 312 is provided with a first pin hole, the connecting portion 314 is provided with a second pin hole, and the pin shaft passes through the first pin hole and the pin hole so that the left crossbeam portion 312 and the connecting portion 314 can be pivoted. Similarly, the right crossbeam portion 316 and the connecting portion 314 can also be articulated in the way of a pin hole and a pin shaft. Of course, the articulated structure can also be other structures as long as it can achieve the pivoting between the left crossbeam portion 312 and the connecting portion 314, and the pivoting between the right crossbeam portion 316 and the connecting portion 314.

[0123] As Figures 13 - 14As shown, in some embodiments, the left crossbeam portion 312 and the connecting portion 314, and the right crossbeam portion 316 and the connecting portion 314 are hinged by means of a hinge assembly. That is, the crossbeam module 300 includes a hinge assembly 320. A set of the hinge assemblies 320 is installed between the left crossbeam portion 312 and the connecting portion 314, and another set of the hinge assemblies 320 is installed between the right crossbeam portion 316 and the connecting portion 314.

[0124] As Figure 16 shown, the hinge assembly 320 includes a first fixed seat 321, a second fixed seat 322, and a rotating shaft 323. The first fixed seat 321 is hinged to the second fixed seat 322 through the rotating shaft 323, so that the first fixed seat 321 and the second fixed seat 322 can rotate relative to each other through the rotating shaft 323. In this embodiment, the first fixed seat 321 is installed on the left crossbeam portion 312, the second fixed seat 322 is installed on the connecting portion 314, and the rotating shaft 323 is located at one end of the crossbeam 310 facing the base module 100. Wherein, the shapes of the first fixed seat 321 and the second fixed seat 322 are approximately semi-frame-shaped. The semi-frame-shaped first fixed seat 321 and second fixed seat 322 can quickly cover the crossbeam 310 to achieve quick installation. In order to accurately position the installation positions of the first fixed seat 321 and the second fixed seat 322, the first fixed seat 321 is provided with a plurality of first positioning convex columns (not labeled), the second fixed seat 322 is provided with a plurality of second positioning convex columns (not labeled), the left crossbeam portion 312 is provided with a plurality of first positioning holes, and the right crossbeam portion 316 is provided with a plurality of second positioning holes. Each of the first positioning convex columns is correspondingly inserted into a first positioning hole, and each of the second positioning convex columns is correspondingly inserted into a second positioning hole, so as to quickly install the hinge assembly to the crossbeam 310.

[0125] As Figures 18 - 19 , in some embodiments, the first fixed seat 321 is provided with a first connecting sleeve 3211, the second fixed seat 322 is provided with a second connecting sleeve 3221, and the first connecting sleeve 3211 and the second connecting sleeve 3221 are connected by the damping rotating shaft 323, so that the first fixed seat 321 and the second fixed seat 322 can rotate relative to each other.

[0126] In some embodiments, the damping rotating shaft 323 includes a first rotating shaft 3232 provided with a fixed end 3231 and a locking nut 3233. Both the first connecting sleeve 3211 and the second connecting sleeve 3221 are sleeved on the first rotating shaft 3221, and the locking nut 3233 is threadedly connected to the end of the first rotating shaft 3232. In this embodiment, the second connecting sleeve 3221 is disposed between the first connecting sleeve 3211 and the fixed end 3231 of the first rotating shaft.

[0127] A first gasket 3234 is provided between the fixed end 3231 of the first rotating shaft and the second connecting sleeve 3221, between the first connecting sleeve 3211 and the second connecting sleeve 3221, and between the locking nut 3233 and the first connecting sleeve 3211. The first gasket 3234 is used for spacing and protecting the mounting surfaces of the first connecting sleeve 3211 and the second connecting sleeve 3221.

[0128] In some embodiments, a second gasket 3235 is provided between the locking nut 3233 and the first gasket 3234, and between the fixed end 3231 of the first rotating shaft and the first gasket 3234. The second gasket 3235 is fixed to the first connecting sleeve 3211, and the second gasket 3535 is used for positioning part of the first gasket 3234 to prevent the first gasket 3234 from axially moving.

[0129] A third gasket 3236 is provided between the first connecting sleeve 3211 and the locking nut 3233. Specifically, the third gasket 3236 is disposed between the locking nut 3233 and the second gasket 3235. The third gasket 3236 is used to provide a preloading elastic force to ensure that the locking nut 3233 does not cause damping failure of the damping rotating shaft due to loosening during the long-term rotational operation of the damping rotating shaft.

[0130] In some embodiments, the first gasket 3234 is also provided between the locking nut 3233 and the third gasket 3236, and between the third gasket 3236 and the second gasket 3235.

[0131] In some embodiments, a strip-shaped hole is provided in the middle of the first gasket 3234, the second gasket 3235, and the third gasket 3236. The first gasket 3234, the second gasket 3235, and the third gasket 3236 are all positioned on the first rotating shaft 3232 through their respective strip-shaped holes.

[0132] In some embodiments, the damping rotating shaft 323 is a metal damping rotating shaft structure, wherein the first rotating shaft 3232, the locking nut 3233, the first gasket 3234, the second gasket 3235, and the third gasket 3236 are all metal structures.

[0133] In some embodiments, the first gasket 3234 is a friction damping washer, the second gasket 3235 is a positioning washer, and the third gasket 3236 is a bowl-shaped elastic washer.

[0134] In some embodiments, to further enhance the damping of the damping rotating shaft 323, the hinge assembly 320 further includes an adjusting plate 324. One end of the adjusting plate 324 is fixed to the first fixed seat 321. The other end of the adjusting plate 324 includes a third connecting sleeve 3241. The third connecting sleeve 3241 is sleeved on the first rotating shaft 3232, and the third connecting sleeve 3241 is disposed between the fixed end 3231 of the first rotating shaft and the second connecting sleeve 3221.

[0135] It should be noted that the first gasket 3234 and the second gasket 3235 located between the fixed end 3231 of the first rotating shaft and the second connecting sleeve 3221 are both disposed between the third connecting sleeve 3241 and the fixed end 3231 of the first rotating shaft, and the second gasket 3235 is fixed to the third connecting sleeve 3241.

[0136] It can be understood that a first gasket 3234 is provided between the third connecting sleeve 3241 and the second connecting sleeve 3221 to protect the installation surface of the third connecting sleeve 3241.

[0137] With the arrangement of the damping rotating shaft 323, the first fixed seat 321 can rotate relative to the second fixed seat 322 only under an external force.

[0138] Such as Figure 17As shown, in some embodiments, the crossbeam module 300 further includes a locking assembly 330. The locking assembly 330 is installed on the hinge assembly 320. The locking assembly 330 is used to lock the first fixing seat 321 and the second fixing seat 322 so that the crossbeam 310 is in an unfolded state. Specifically, the locking assembly 330 includes a first fixing block 331, a second fixing block 332, a rotating rod 333, and a clamping member 334. The first fixing block 331 is installed on the first fixing seat 321. The second fixing block 332 is installed on the second fixing seat 322. One end of the rotating rod 333 is rotatably installed on the second fixing block 332, and the other end of the rotating rod 333 is installed with the clamping member 334. Among them, the first fixing block 331 is provided with a notch 3311 for the rotating rod 333 to be inserted into. When the rotating rod 333 rotates to be embedded in the notch 3311, the clamping member 334 abuts against the edge of the notch 3311, so that the first fixing block 331 and the second fixing block 332 are on the same horizontal plane, so as to lock the first fixing seat 321 and the second fixing seat 322.

[0139] Further, in order to enable the first fixing block 331 and the second fixing block 332 to be accurately docked, and at the same time ensure that the left crossbeam portion 312 and the connecting portion 314 are accurately spliced, the first fixing block 331 is provided with a protruding portion 3312, and the second fixing block 332 is provided with a recessed portion 3322. The protruding portion 3312 and the recessed portion 3322 cooperate with each other. In this embodiment, the shape of the protruding portion 3312 is V-shaped, and the recessed portion 3322 is a V-shaped groove.

[0140] When the protruding portion 3312 and the recessed portion 3322 are inserted in the positive direction, the first fixing seat 321 has moved to a position where it cooperates with the second fixing seat 322, and the first fixing seat 321 has rotated to the limit position. At this time, the rotating rod 333 is rotated to be embedded in the notch 3311 so that the clamping block 334 abuts against the first fixing block 321, thereby realizing the locking of the left crossbeam portion 312 and the connecting portion 314. Similarly, the right crossbeam portion 316 and the connecting portion 314 are also locked by the locking assembly.

[0141] In some other embodiments, the above-mentioned locking assembly 330 may be the following structure:

[0142] Such as Figures 18 - 20As shown in the figure, the locking component 330 includes a first fixing block 331', a second fixing block 332', a locking block 333', a rotating body 335' and an elastic member 337'. The first fixing block 331' is installed on the first fixing seat 321, the second fixing block 332' is installed on the second fixing seat 322', the locking block 333' is fixed to the first fixing block 331', and the rotating body 335' is rotatably installed on the second fixing block 332'. The locking block 333' is installed on the first fixing seat 321', the rotating body 335' is rotatably installed on the second fixing seat 322', one end of the rotating body 335' is used to cooperate with the locking block 333' (engage or disengage), the other end of the rotating body 335' is connected with the elastic member 337', the elastic member 337' is arranged between the second fixing seat 322' and the other end of the rotating body 335', and the elastic member 337' is used to provide a restoring force to make the rotating body 335' engage with the locking block 333'. In this way, the second fixing seat 322' can be locked and unlocked.

[0143] In the embodiment of the present application, the required position refers to the position where the second fixing seat 322' is located when the second fixing seat 322' and the first fixing seat 321' are flush.

[0144] It can be understood that locking the second fixing seat 322' means restricting the second fixing seat 322' from rotating relative to the first fixing seat 321', and unlocking the second fixing seat 322' means that the second fixing seat 322' can rotate relative to the first fixing seat 321.

[0145] Specifically, a rotating seat 334' is provided on the second fixing block 332', an installation space 3341' is formed on the rotating seat 334', a first installation hole 3342' and a second installation hole 3343' are respectively formed at both ends of the installation space 3341', the lower part 3351' of the rotating body 335' is placed in the installation space 3341', a third installation hole 33511' is formed in the lower part 3351' of the rotating body 335', and a second rotating shaft 336' sequentially passes through the first installation hole 3342', the third installation hole 33511' and the second installation hole 3343', so that the rotating body 335' can rotate relative to the second fixing seat 322.

[0146] It can be understood that since the lower part 3351' of the rotating body 335' can rotate relative to the rotating seat 334' in the installation space 3341', the lower part 3351' of the rotating body is an arc surface.

[0147] In some embodiments, the locking block 333' includes a first inclined surface 3331' and a second inclined surface 3332'. A first end of the rotating body 335' has a hook 3352'. A second end 3353' of the rotating body 335' is used to connect the elastic member 337'. The first inclined surface 3331' acts on the hook 3352' to push the hook 3352' when the first fixing seat 321' approaches the second fixing seat 322', so that the elastic member 337' is deformed. The second inclined surface 3332' is used to engage with the second inclined surface 3332' under the restoring force of the elastic member 337'.

[0148] It can be understood that to ensure the feasibility of the solution, when the rotating body 335' is not under external force and the second fixing seat 322' is flush with the first fixing seat 321', the hook 3352' is disengaged from the first inclined surface 3331'.

[0149] It should be noted that the lower part 3351' of the rotating body 335' is located between the first end and the second end of the rotating body 335'.

[0150] For convenience of description, in the embodiments of the present application, the horizontal plane where the first fixing block 331' is located is the x direction, and the direction perpendicular to the x direction is the y direction.

[0151] In some embodiments, the included angle between the first inclined surface 3331' and the x direction is 30°.

[0152] In some embodiments, the included angle range between the second inclined surface 3332' and the y direction is 0 to 5°.

[0153] In some embodiments, to make the first inclined surface 3331' more likely to push the hook 3352', the hook 3352' includes a third inclined surface 33521', and the third inclined surface 33521' is used to contact the first inclined surface 3331'.

[0154] The setting of the third inclined surface 33521' makes the contact between the hook 3352' and the first inclined surface 3331' a line contact, reducing the friction between the hook 3352' and the first inclined surface 3331', so that the first inclined surface 3331' is more likely to push the hook 3352'.

[0155] In some embodiments, when the hook 3352' is engaged with the second inclined surface 3332', the third inclined surface 3351' is parallel to the first inclined surface 3331'.

[0156] In some embodiments, the elastic member 337' is a spring.

[0157] In some embodiments, to prevent the elastic member 337' from popping out during the rotation of the rotating body 335', a first mounting groove 33531' and a second mounting groove 3322' are respectively provided on the second end 3353' of the rotating body 335' and the second fixing block 332', and the elastic member 337' is placed between the first mounting groove 33531' and the second mounting groove 3322'.

[0158] It can be understood that when the hook 3352' is engaged with the locking block 333', the elastic member 337' is in its original length or a compressed state.

[0159] It should be noted that to ensure the feasibility of the solution, when the rotating body 335' is not in contact with the locking block 333', that is, when the elastic member 337' does not undergo elastic deformation, the hook 3352' should be located above the second fixing block 332', and the included angle between the upper end surface or the third inclined surface of the rotating body and the plane where the second fixing block 332' is located is a preset angle. The preset angle can be set according to the actual situation to ensure that when the second fixing seat 322 rotates close to the first fixing seat 321, the hook 3352' can contact the first inclined surface 3331'.

[0160] In some embodiments, to prevent the rotating body 335' from rotating under an external force after the hook 3352' is engaged with the locking block 333', the locking assembly 320' further includes a locking knob 338'. A fourth mounting hole 33532' is provided at the second end of the rotating body, and the locking knob 338' is threadedly connected to the fourth mounting hole 33532'. After the hook is engaged with the locking block 333', the locking knob 338' is tightened until the end of the locking knob 338' abuts against the second fixing block 332'.

[0161] In some embodiments, the end of the locking knob 338' is an arc surface.

[0162] It should be noted that the first mounting groove 33531' is provided close to the middle part 3351' of the rotating body, and the fourth mounting hole 33532' is provided away from the middle part 3351' of the rotating body.

[0163] For the convenience of description, here, the hinge assembly 320 and the locking assembly 330 at the connection between the connecting portion 314 and the right crossbeam portion 316 are taken as examples for narration, and the direction of rotation close to the second fixing seat 322' is defined as the counterclockwise direction, and the direction of rotation away from the second fixing seat 322 is defined as the clockwise direction.

[0164] During specific implementation, the first fixing seat 321' is pushed to rotate the first fixing seat 321' in the direction close to the second fixing seat 322' until the hook 3352' abuts against the first inclined surface 3331', as Figure 21 shown; the first fixing seat 321' is continuously pushed towards the second fixing seat 322', and the first inclined surface 3331' pushes against the hook 3352' under the push of the first fixing seat 321'. The hook 3352' rotates clockwise under the action of the first inclined surface 3331' and compresses the elastic member 337', as Figure 22 shown, until the first fixing seat 321' is flush with the second fixing seat 322'. The rotating body 335' rotates counterclockwise under the restoring force of the elastic member 337' to make the hook 3352' snap onto the second inclined surface 3332'; the locking knob 338' is tightened until the end of the locking knob 338' abuts against the second fixing block 332' to complete the locking; when unlocking is required, that is, when the first fixing seat 322' needs to rotate away from the second fixing seat 322', the locking knob 338' is loosened to make the end of the locking knob 338' have a preset distance from the second fixing block 332'; the locking knob 338' is pressed, and the rotating body 335' rotates clockwise until the hook 3352' disengages from the second inclined surface 3332'. At this time, the first fixing seat 321' can be rotated clockwise. It can be understood that the preset distance is greater than the distance from the end of the hook 3352' to the top of the locking block 3332' when the hook 3352' is snapped onto the second inclined surface 3332'.

[0165] Please refer to again Figure 16, in some embodiments, in order to accurately know whether the left crossbeam portion 312 and the right crossbeam portion 316 have rotated to the limit position where they are connected to the connecting portion 314, the crossbeam module 300 further includes a detection sensor 301. The detection sensor 301 is installed on the crossbeam 310 and is used to detect whether the left crossbeam portion 312 and the right crossbeam portion 316 are closed to the connecting portion 314. In this embodiment, the detection sensor 301 is a proximity sensor. An end of the left crossbeam portion 312 is provided with a first mounting groove 3121, and an end of the connecting portion 314 is provided with a second mounting groove 3141. A stopper 3122 is mounted on the left crossbeam portion 312 near the connecting portion 314 in the first mounting groove 3121. A support member 3142 is installed in the second mounting groove 3141 of the connecting portion 314, and the proximity switch is supported by the support member 3142. When the left crossbeam portion 312 rotates to be in a horizontal line with the connecting portion 314, the proximity switch will detect that the stopper 3122 is in place, thereby confirming that the left crossbeam portion 312 has rotated to the limit position where it is locked to the connecting portion 314. In this embodiment, the first mounting groove 3121 is shielded by the first fixing seat 321 and is not exposed to the outside, and the second mounting groove 314 is shielded by the second fixing seat 322 and is not exposed to the outside. This is more conducive to creating a detection environment for the detection sensor and avoiding abnormal detection caused by excessive external light. Similarly, similar structures such as the first mounting groove 3121, the second mounting groove 3141, the stopper 3122, and the proximity switch are provided between the right crossbeam portion 316 and the connecting portion 314 to determine whether the right crossbeam portion 316 has rotated to the limit position where it is connected to the connecting portion 314.

[0166] Please refer to again Figure 14, in some embodiments, the crossbeam module 300 further includes a buffer member 340. The buffer member 340 is installed on the crossbeam 310 and is used to slow down the rotation speed of the left crossbeam portion 312 and the right crossbeam portion 316 relative to the connecting portion 314. In this embodiment, the buffer member 340 is a gas spring. One end of the gas spring is connected to the left crossbeam portion 312, and the other end of the gas spring is connected to the connecting portion 314. In this way, when the crossbeam 310 is folded, the left crossbeam portion 312 rotates relative to the connecting portion 314. At this time, the left crossbeam portion 312 will slowly move downward towards the ground until it reaches the limit position, avoiding the sudden drop of the left crossbeam portion 312 towards the ground and exacerbating the wear of the hinge assembly 320. It should be understood that the buffer member 340 is not limited to the above-mentioned gas spring, and can also be other structures, such as a tension spring or a leather ring, as long as it can slow down the folding speed of the left crossbeam portion 312 towards the base module 100.

[0167] In some embodiments, the connecting portion 314 is provided with a first sliding groove 3144, and the left crossbeam portion 312 and the right crossbeam portion 316 are provided with second sliding grooves 3124. The two second sliding grooves 3124 are respectively located at both ends of the first sliding groove 3144, and the first sliding groove 3144 communicates with the two second sliding grooves 3144.

[0168] In order to more accurately control the position of the calibration element on the crossbeam module 300 and improve the accuracy during ADAS calibration, the crossbeam module 300 further includes a hanging mechanism. The hanging mechanism is installed on the crossbeam 310 and is used to hang the calibration element.

[0169] Such as Figure 23As shown, the hanging mechanism includes a main slide plate assembly 350, and the main slide plate assembly 350 is installed on the cross beam 310. Among them, it can reciprocate axially along the cross beam 310. Specifically, the main slide plate assembly 350 includes a main slide plate 351 and at least two rolling rod members 352. One ends of at least two of the rolling rod members 352 are all installed on the main slide plate 351, and the other ends of at least two of the rolling rod members 352 are installed in the first chute 3144. In this way, the main slide plate 351 can slide in the first chute 3144 through the rolling rod members 352 to provide different hanging positions for the calibration element. In this embodiment, two gourd-shaped mounting holes 3511 are provided on the main slide plate 351, and the two mounting holes 3511 are symmetrically distributed. The mounting holes 3511 are used for the user to hang the calibration element, and at this time, tools such as hooks can be used to achieve the hanging. Further, the main slide plate 351 is also provided with arc holes 3512. The number of the arc holes 3512 is two, and the two arc holes 3512 are symmetrically distributed. The arc holes 3512 can also be used for hanging the calibration element.

[0170] The rolling rod member 352 includes a connecting rod 3521, a bearing 3522 and a wheel sleeve 3523. One end of the connecting rod 3521 is fixedly connected to the main slide plate 351, the other end of the connecting rod 3521 is connected to the bearing 3522, and the wheel sleeve 3523 is sleeved on the bearing 3522. In this way, when the main slide plate 351 is pushed, the bearing 3522 and the wheel sleeve 3523 will roll relative to the connecting rod 3521, so as to realize the movement of the main slide plate 351.

[0171] It should be understood that although the shape of the mounting holes 3511 is gourd-shaped and the number is two in the above-mentioned embodiment, the shape and number of the mounting holes 3511 are not limited thereto, as long as they can be used for hanging the calibration element. Similarly, the number of the arc holes 3512 is not limited to the two mentioned above.

[0172] Further, the main slide plate assembly 350 includes a screw member 353 and a stopper 354. The main slide plate 351 is provided with a threaded hole 3513. The screw member 353 is screwed into the threaded hole 3513, and the screw member 353 is connected to the stopper 354. In this embodiment, the main slide plate 351 is provided with a mounting portion, and the threaded hole 3513 is provided on the mounting portion. One end of the screw member 353 is a nut, the other end of the screw member 353 is a screw with threads, and the outer surface of the screw has threads. The screw passes through the threaded hole 3513 and is fixedly connected to the stopper 354.

[0173] Thus, when the screw member 353 is screwed in the first direction, the stopper 354 gradually moves towards and abuts against the groove wall of the first chute 3144, so that the main slide plate 351 is in a locked state. At this time, the main slide plate 351 cannot move freely, which can effectively ensure that the position of the calibration element does not change during ADAS calibration; when the screw member 353 is screwed in the second direction, the stopper 354 gradually moves away from the groove wall of the first chute 3144, so that the main slide plate 351 is in an unlocked state. At this time, the main slide plate 351 can slide along the first chute 3144. It should be understood that the first direction and the second direction are two opposite directions. For example, if the first direction is the clockwise direction, the second direction is the counterclockwise direction.

[0174] As Figures 24 - 25 shown, in some embodiments, the hanging mechanism further includes two sub-slide plate assemblies 360. The sub-slide plate assemblies 360 are installed in the second chute 3124, and the sub-slide plate assemblies 360 can slide on the second chute 3124. In this embodiment, a set of the sub-slide plate assemblies 360 is provided on each of the left crossbeam portion 312 and the right crossbeam portion 316. The two sets of sub-slide plate assemblies 360 together realize hanging the calibration element.

[0175] Specifically, the sub-slide plate assembly 360 includes a sub-slide plate 361 and at least two pulley rods 362. One end of each pulley rod 362 is detachably installed on the sub-slide plate 361, and the other end of each pulley rod 362 is installed in the second chute 3124. Thus, the sub-slide plate 361 can slide in the second chute 3124 by means of the pulley rods 362 to provide different hanging positions for the calibration element.

[0176] Two embedding ports 3611 are provided at one end of the sub-slide plate 361 away from the second chute 3124. Magnetic members are embedded in the embedding ports 3611. The magnetic members can be used to attract the calibration element. At this time, the calibration element needs to be made of a magnetic material or have a partially magnetically adsorbable area. The magnetic members on the two sub-slide plates 361 together attract the calibration element to play a role in hanging the calibration element. Among them, the magnetic member can be a magnet or other magnetic objects. Further, a notch 3612 is provided at the side end of the sub-slide plate 361. The notch 3612 is used to clamp the calibration element. Specifically, in use, the two ends of the calibration element are respectively accommodated in the notches 3612 on the two sliding plates 361 to jointly clamp the calibration element. Among them, the notches 3612 on the two sliding plates 361 need to face the position of the middle fixed column 210 at the same time.

[0177] The pulley rod 362 has a similar structure to the rolling rod 352 , both of which achieve rolling with the help of bearings. The pulley rod 362 will not be described in detail here.

[0178] It should be understood that in order to know the position of the main slide assembly 350 and the auxiliary slide assembly 360 on the beam 310, the beam 310 is provided with a scale bar 318, and the scale bar 318 has scales. In this embodiment, the scale bar 318 is arranged along the axial direction of the beam 310.

[0179] like Figure 25 As shown, the auxiliary slide assembly 360 also includes a brake structure, which is mounted on the auxiliary slide 361. The brake structure is used to stop the auxiliary slide 361 to prevent the auxiliary slide 361 from moving arbitrarily and causing inaccurate ADAS calibration. In this embodiment, the brake structure includes a mounting base 363, a support shaft 364, a torsion spring 365, a wrench 366, and a brake member 367. The mounting base 363 is mounted on the auxiliary slide 361, the support shaft 364 is mounted on the mounting base 363, the torsion spring 365 and the wrench 366 are both sleeved on the support shaft 364, one end of the torsion spring 365 abuts the auxiliary slide 361, and the other end of the torsion spring 365 abuts the wrench 366. One end of the brake member 367 is connected to the wrench 366, and the other end of the brake member 367 abuts the crossbeam 310. In this way, under the action of the stop member 367, the auxiliary slide 361 will be blocked and cannot move freely, and the auxiliary slide 361 is in a locked state; when the wrench 366 is bent, and the wrench 366 drives the stop member 367 to move in the direction away from the beam 310, the auxiliary slide 361 can slide in the second sliding groove 3124 through the pulley rod 362, releasing the wrench 366. Under the action of the torsion spring 365, the wrench 366 will push the stop member 367 to move in the direction close to the beam 310 and abut, so that the auxiliary slide 361 returns to the locked state.

[0180] In some embodiments, the auxiliary slide assembly 360 further includes a pointer 368. The pointer 369 is detachably mounted on the auxiliary slide 361. The pointer 368 is used to indicate the scale position of the auxiliary slide 361 on the beam 310. That is, the distance moved by the auxiliary slide 361 or the distance from the center of the beam 310 can be determined based on the scale of the scale bar 318 indicated by the pointer 368.

[0181] With the above structure, when the user needs to adjust the position of the secondary slide plate 361, the locking state of the secondary slide plate 361 needs to be released by the wrench 366, and then the secondary slide plate 361 can be moved. In this way, the position of the secondary slide plate 361 can be effectively locked, improving the stability during ADAS calibration.

[0182] As Figure 26 shown, in some embodiments, the hanging mechanism further includes a suspension rod assembly 370. The suspension rod assembly is installed on the cross beam 310, and the suspension rod assembly 370 is used to support the calibration element. Specifically, the suspension rod assembly 370 includes a connection block 371, a receiving rod 372, and a support rod 373. The connection block 371 is installed on the cross beam 310, the receiving rod 372 is connected to the connection block 371, the receiving rod 372 is provided with a receiving space, the support rod 373 is received in the receiving space, and the support rod 373 can extend or retract relative to the receiving rod 372. The support rod 373 is used to support the calibration element.

[0183] The receiving rod 372 has a sliding hole 3721 and a positioning hole 3722. The shape of the sliding hole 3721 is a long hole, and the sliding hole 3721 is arranged along the axial direction of the receiving rod 372. The sliding hole 3721 is provided at both opposite ends of the receiving rod 372. The number of the positioning holes 3722 is two, and the two positioning holes 3722 are arranged at an axial interval along the receiving rod 372.

[0184] The support rod 373 is provided with a spring bead 3731, a guide shaft 3732, and a hanging block 3733. The spring bead 3731 is located at one end of the support rod 373, the hanging block 3733 is located at the other end of the support rod 373, the guide shaft 3732 is located between the spring bead 3731 and the hanging block 3733, the guide shaft 3732 penetrates through the opposite ends of the support rod 373, and the ends of the guide shaft 3732 extend out of the sliding hole 3721. Among them, the spring bead 3731 can protrude out of the receiving space and be embedded into one of the positioning holes 3722 to adjust the length of the support rod 373 extending out of the receiving rod 372. The hanging block 3733 is provided with a clamping groove 37331, and the clamping groove 37331 is used to clamp the calibration element.

[0185] When the user pulls the support rod 373, the spring bead 3731 will retract into the receiving space. Under the action of the guide shaft 3732, the support rod 373 will be drawn out of the receiving rod 372 along the sliding hole 3722 directionally until the spring bead 3731 is embedded into the other positioning hole 3722 again. At this time, the length of the support rod 373 is adjusted to better hang the calibration element according to needs.

[0186] It should be understood that the number of the positioning holes 3722 is not limited to the two mentioned in the above embodiments, and the number can be increased as needed. The adjusting structure of the support rod 373 relative to the receiving rod 372 is not limited to the form of spring beads and positioning holes. Any structure that can adjust the length of the support rod 373 relative to the receiving rod 372 is applicable. For example, a pin shaft and pin holes can be used for mutual insertion. At this time, a plurality of pin holes are axially provided on the receiving rod 372, and a plurality of pin holes are also provided on the support rod 373. By inserting the pin shaft into the pin holes at different positions of the receiving rod 372 and the support rod 373, the relative length of the two can be fixed.

[0187] In some embodiments, the connecting block 371 is hinged to the receiving rod 372. The hanging assembly 370 further includes a magnetic attraction member 374. A magnetic block (not labeled) is installed on the cross beam 310. Both the magnetic attraction member 374 and the magnetic block have magnetism, and the magnetic attraction member 374 and the magnetic block can be magnetically attracted. Thus, when the receiving rod 372 rotates towards the direction close to the cross beam 310, the magnetic attraction member 374 and the magnetic block are magnetically attracted, so that the receiving rod 372 can be folded and stored relative to the cross beam 310. In this embodiment, both the connecting block 371 and the magnetic block are installed on the connecting portion 314, so that when the cross beam 310 is in a folded state, the receiving rod 372 can also be magnetically attracted by the magnetic attraction member 374 and the magnetic block, so that the receiving rod 372 and the connecting portion 314 are approximately on the same horizontal line, thereby minimizing the volume of the vehicle measuring device 900 and stably storing the receiving rod.

[0188] It should be understood that there are various supporting methods for the calibration element. For example: (1) suspension is achieved through the two mounting holes 3511 or the two arc holes 3512 on the main sliding plate 351; (2) the calibration element is jointly attracted by magnetic members installed on the two sub-sliding plates 361; (3) the calibration element is jointly clamped by the notch 3612 on the side of the two sub-sliders 361; (4) the calibration element is jointly supported by the notch 3612 on the side of the two sub-sliders 361 and the two hanging assemblies 370.

[0189] Please refer to Figures 27 - 29 In some embodiments, the cross beam module 300 further includes an adjusting device. The adjusting device includes an adjusting mechanism 380. The adjusting mechanism 380 is connected to the moving column assembly 220. The cross beam 310 is installed on the adjusting mechanism 380. The adjusting mechanism 380 is used to adjust the position of the cross beam relative to the fixed column.

[0190] The adjusting mechanism 380 includes a first connecting plate 381, a second connecting plate 382, a support plate 383 and an adjusting component 384. The first connecting plate 381 is connected to the cross beam 310, the second connecting plate 382 is connected to the lifting plate 223, the support plate 383 is located between the first connecting plate 381 and the second connecting plate 382, and the adjusting component 384 is installed on the first connecting plate 381, the second connecting plate 382 and the support plate 383. The adjusting component 384 is used to adjust the relative position between the cross beam 310 and the fixed column 210. In this embodiment, the support plate 383 is in the shape of a "work" character. Of course, the shape of the support plate 383 can also be other shapes, not limited to the work character shape in this embodiment.

[0191] In some embodiments, in order to enable the cross beam 310 to better fit tightly with the first connecting plate 381 and facilitate installation, a support plate (not labeled) is installed at the bottom of the first connecting plate 381. Both ends of the support plate protrude from the edge of the first connecting plate 381, so that when the first connecting plate 381 is in tight fit with the cross beam 310, the support plate can support the bottom of the cross beam 310, thereby realizing quick positioning and installation.

[0192] The adjusting component 384 includes a rotating shaft 3841, a first driving rod 3842, an elastic member 3843 and an installation rod 3844. The rotating shaft 3841 is rotatably installed in the middle of the support plate 383. The first connecting plate 381 is connected to the rotating shaft 3841. The first driving rod 3842 is screwed to the support plate 383, and one end of the first driving rod 3842 is connected to one end of the first connecting plate 3841. The installation rod 3844 is installed at the other end of the first connecting plate 381, and the installation rod 3844 faces the support plate 383. The elastic member 3843 is sleeved on the installation rod 3844.

[0193] When the user turns the first drive rod 3842 and makes one end of the first connecting plate 381 move away from the support plate 383, under the action of the rotating shaft 3841, the other end of the first connecting plate 381 will move towards the support plate 383 and squeeze the elastic member 3843. Thus, the first connecting plate 381 drives the cross beam 310 to rotate around the fixed column 210. Conversely, when the first drive rod 3842 is turned in the reverse direction, one end of the first connecting plate 381 will move towards the fixed column 210, and the other end of the first connecting plate 381 will move away from the support plate 383 under the action of the elastic member 3843. In this way, the vertical distance between the left cross beam portion 312 and the fixed column 210 can be adjusted as needed. In this embodiment, the elastic member 3843 is a spring. Of course, the elastic member 3843 is not limited to the spring in this embodiment. For example, the elastic member 3843 can also be silicone rubber, etc.

[0194] Thus, the adjusting mechanism can adjust the rotation angle of the cross beam relative to the column module, that is, realize the rotation of the cross beam 31 around the central axis of the column module 200.

[0195] As Figure 29 shown, further, the adjusting assembly 384 further includes a receiving member 3845. One end of the receiving member 3845 has an opening 38451. The support plate 383 is provided with a communication hole 3831. The receiving member 3845 is installed on the support plate 383. The opening 38451 is communicated with the communication hole 3831. A part of the elastic member 3843 is received in the receiving member 3845. One end of the elastic member 3843 abuts against the bottom of the receiving member 3845, and the other end of the elastic member 3843 abuts against the first connecting plate 381. Wherein, the aperture of the communication hole 3831 should be larger than the shaft diameter of the mounting rod 3844 so that there is an activity space when the first connecting plate 381 drives the mounting rod 3844 to rotate. In this embodiment, the receiving member 3845 includes a boss 38453 and a cylinder 38454. The cylinder 38454 is connected to the boss 38453. One end of the cylinder 38454 is provided with the opening 38451. The opening 38451 penetrates through the boss 38453. The elastic member 3843 is received in the cylinder 38454. One end of the elastic member 3843 abuts against the bottom of the cylinder 38454, and the other end abuts against the first connecting plate 381. In this way, when the other end of the first connecting plate 381 squeezes the elastic member 3843, the elastic member 3843 will be compressed into the cylinder 38454, so that the first connecting plate 381 has more activity stroke.

[0196] As shown Figure 31 In some embodiments, the adjusting assembly 384 further includes a second screw 3846, a rack 3847, a gear 3848, and a sliding bar 3849. The sliding bar 3849 is mounted on the support plate 383 and is slidable relative to the support plate 383 along a preset direction. The second connecting plate 382 is connected to the sliding bar 3849. The rack 3848 is mounted on the support plate 383. The second connecting plate 382 is provided with an avoidance hole 3822. One end of the second screw 3846 mounts the gear 3848, and the other end of the second screw 3846 passes through the avoidance hole 3822. The gear 3848 meshes with the rack 3847. Thus, when the second screw 3846 is turned, the gear 3848 will drive the rack 3847 to drive the support plate 383 to move along the preset direction. In this embodiment, the preset direction refers to the direction in which the I-shaped support plate 383 is stretched. The sliding bar 3849 is slidably mounted on the support plate 383, which can be achieved by providing guide sliders 3850 with protruding surfaces on the support plate 383 and grooves on the guide sliders 3850. The sliding bar 3849 is cooperatively mounted with the guide sliders 3850 and can slide through the grooves.

[0197] When the preset direction is on the same horizontal line as the direction of the cross beam 310, turning the second screw 3846 can move the cross beam 310 relative to the fixed column 210 to the left or right, thereby adjusting the distances from the centers of the left cross beam portion 312 and the right cross beam portion 316 to the central axis of the fixed column 210.

[0198] Further, in order to prevent the support plate 383 from detaching from the second connecting plate 382 under the drive of the second screw 3846, two limiting blocks 3833 are provided on the support plate 383. The two limiting blocks 3833 are respectively located at both ends of the sliding bar 3849. Thus, restricted by the limiting blocks 3833, the guide sliders 3850 can only move a certain stroke, avoiding the guide sliders 3850 detaching from the guide bar 3849. At the same time, the left and right moving strokes of the rack 3848 are the same as the stroke that the guide sliders 3850 can move.

[0199] As shown Figure 32As shown, in some embodiments, the adjustment assembly 384 further includes a locking structure, which is installed on the second connecting plate 382 and is used to lock the second screw 3846 to prevent the second screw 3846 from rotating due to manual operation errors. In this embodiment, the locking structure includes a clamp member 3851 and a locking member 3852. The clamp member 3851 has an annular hole 38512. The clamp member 38512 is sleeved on the second screw 3846 through the annular hole 38512, and the clamp member 3851 is fixedly installed on the second connecting plate 382. The locking member 3852 is hinged to the clamp member 3851. Among them, the diameter of the annular hole 38512 is larger than the shaft diameter of the second screw 3846. The shape of one end of the locking member 3852 for connecting with the clamp member 3851 is cam-shaped.

[0200] When the locking member 3852 is in the first position, at this time the locking member 3852 does not squeeze the clamp member 3851 to twist the second screw 3846, and the support plate 383 can move relative to the second connecting plate 382. Rotate the locking member 3852 to the second position, the locking member 3852 will squeeze the clamp member 3851, and make the hole wall of the annular hole 38512 closely fit the second screw 3846. At this time, the second screw 3846 will be in a locked state.

[0201] In some embodiments, the adjustment mechanism further includes a level bead 3853, which is installed on the support plate 383 and is used to detect whether the cross beam 310 is in a horizontal state. If the level bead 3853 shows that the cross beam 310 is not in a horizontal state, the foot cup 113 of the base module 100 can be adjusted until the level bead 3853 shows that the cross beam 310 is in a horizontal state. In this way, the error generated during the calibration of the vehicle measuring device 900 can be effectively reduced.

[0202] As Figure 28 or Figure 31 , in some embodiments, the support plate 383 is provided with a receiving cavity (not labeled). The cross beam module 300 further includes a laser 390, which is received in the receiving cavity and fixedly connected to the support plate 383. The laser 390 is used to measure the height of the cross beam 310 from the ground.

[0203] Through the above structure, the adjustment mechanism can realize the left and right movement of the cross beam 31 along its central axis direction, and at the same time can realize the rotation of the cross beam 31 around the central axis direction of the column module 200.

[0204] Please refer to again Figure 13In some embodiments, the camera assembly 400 includes a first camera 410 and a second camera 420. The first camera 410 is mounted on the left crossbeam portion 312, for example, at the end of the left crossbeam portion 312, and the second camera is mounted on the right crossbeam portion 316, for example, at the end of the right crossbeam portion 316. The first camera 410 and the second camera 420 are respectively used to obtain images of the wheels on both sides of the vehicle, or to obtain images of targets close to or attached to the wheels on both sides of the vehicle. Furthermore, the camera assembly 400 also includes a third camera 430. The third camera 430 is mounted on the connecting portion 314, and the third camera is used to obtain images of the front area of the vehicle. The first camera, the second camera, and the third camera are detachably mounted on the crossbeam, or the first camera, the second camera, and the third camera are fixedly mounted on the crossbeam.

[0205] Please combine Figure 33 As shown, in some embodiments, the vehicle measurement device 900 further includes a display assembly 500, which is connected to the fixed column 210 and is used to display images captured by the camera assembly. Specifically, the display assembly 500 includes a display screen 510 and a fixed bracket 520, which is mounted on the fixed column 210. The display screen 520 is mounted on the fixed bracket 520.

[0206] Furthermore, the display assembly 500 further includes a folding bracket 530, such as Figure 34 As shown, the folding bracket 530 includes a first fixing plate 531, a second fixing plate 532, a first support arm 533, and a second support arm 534. The first fixing plate 531 is fixedly connected to the display screen 510. One end of the first support arm 533 is hinged to the first fixing plate 531, the other end of the first support arm 533 is hinged to one end of the second support arm 534, the other end of the second support arm 534 is connected to the second fixing plate 532, and the second fixing plate 532 is connected to the fixed bracket 520. The second support arm 534 is rotatable relative to the first fixing plate 531, and the first support arm 533 is rotatable relative to the second support arm 534. Since both the first support arm 533 and the second support arm 534 are rotatable, the display screen 510 can be positioned at different distances from the fixed column 210 according to user needs. When the folding bracket 530 is not in use, the display assembly 500 is located on the side away from the beam module. When the folding bracket 530 is used, the display assembly 500 can be rotated to the same side as the beam module, that is, the side facing the vehicle, so that the user can observe the measurement results or maintenance results in real time when measuring or repairing the vehicle.

[0207] In some embodiments, the vehicle measurement device 900 further includes a main control unit 600, which is installed on the support plate 383, and the main control unit 600 is respectively connected to the display screen 510, the first camera 410, the second camera 420, and the third camera 430. Among them, the first camera 410, the second camera 420, and the third camera 430 can be connected to the main control unit 600 by wire or wirelessly. When connected by wire, the electrical connection lines of the above cameras to the main control unit 600 are stored inside the cross beam 310. The main control unit 600 and the display screen 510 can be wirelessly connected. The main control unit 600 is configured to process the images acquired by the cameras to obtain processed data such as measurement results, calibration results, and guiding steps, and transmit the processed data to the display screen 510 for display. The user can adjust the vehicle or the vehicle measurement device according to the data displayed on the display screen.

[0208] In some embodiments, the vehicle measurement device 900 further includes a support frame 700, which is installed on the fixed column 210, and the support frame 700 is used to support the portable diagnostic device. Among them, the display interface of the portable diagnostic device can be synchronized with the display interface of the display screen 510. The main control unit 600 can be wirelessly connected to the portable diagnostic device, and the main control unit 600 can be used to send the image data acquired by the cameras to the portable diagnostic device for further processing, such as measuring wheel parameters, determining calibration results, obtaining the position information of the vehicle measurement device relative to the vehicle, and determining user guiding operation steps.

[0209] The main control unit 600 of the present application can be electrically connected to all the electronic components involved in the present application, such as the above control system, detection sensors, emergency control buttons, lifting buttons, etc. The main control unit can be used to receive the signals of the electronic components and can send instructions to the connected electrical components.

[0210] For example, when the main control unit receives the signals transmitted by the emergency control button, the lifting button, etc., it can control the control system according to the specific signals, so that the control system controls the drive assembly to perform emergency stop, rise or fall of the cross beam module.

[0211] For another example, the main control unit can receive the signals of the detection sensors and determine whether the cross beam module is currently in the deployed state or the folded state. After the main control unit detects that the cross beam module is in the deployed state, it can allow the control system to turn on the drive assembly. If the main control unit detects that the cross beam module is in the folded state, it does not send instructions to the control system to turn on the drive assembly. Further, the main control unit can also prompt the user through the display screen to put the cross beam assembly in the deployed state.

[0212] For another example, the master controller can also determine whether the crossbeam module is in the deployed state or the folded state based on the images obtained by the first camera and the second camera. For example, the first camera is provided with a self-calibration target, and the second camera is provided with a self-calibration camera for photographing the self-calibration target. If the image photographed by the self-calibration camera contains the self-calibration target, it indicates that the crossbeam module is in the deployed state. If the image photographed by the self-calibration camera does not contain the self-calibration target, it indicates that the crossbeam module is in the folded state.

[0213] Of course, the master controller can also implement other methods of data processing and transmission, which are not limited herein.

[0214] In some embodiments, the vehicle measuring device 900 further includes a handle 720, and the handle 720 is installed at the side end of the fixed column 210.

[0215] Embodiment 2

[0216] As Figure 35 shown, the vehicle measuring device 900' provided by another embodiment of the present invention is different from the above embodiment in that: the laser 390 is installed at the side end of the lifting plate 223, the base module 100' is provided with a through hole 101', and the through hole 101' is located directly below the emitting end of the laser. The laser 390 is used to measure the ground clearance of the crossbeam 310. The laser 390 is arranged at the side end of the lifting plate 223, which is convenient for maintaining the laser 390, and also convenient for replacement and adjusting the light emitting angle of the laser 390.

[0217] Please refer to Figure 36 and 37 , in some embodiments, the base module 100' includes a base 110', at least three universal wheels 120' and a foot brake assembly 130'. Each universal wheel 120' is installed on the base 110', and a plurality of the universal wheels 120' are distributed in a polygon at one end of the base 110' away from the column module 200, and the foot brake assembly 130' is installed on the base 110'. In this embodiment, the base 110' is provided with the through hole 101', and the number of the universal wheels 120' is four. The four universal wheels 120' are respectively distributed at the four corners of the base 110', so as to jointly and stably support other components away from the base module 100'.

[0218] The foot brake assembly 130' includes a locking pedal 131', a tensioning pedal 132', a receiving cylinder 133', a braking block 134' and a connecting pin 135'. The receiving cylinder 133' is installed on the base 110'. The receiving cylinder 133' is provided with a guiding groove 1331'. The braking block 134' is partially received in the receiving cylinder 133'. The connecting pin 135' is rotatably connected to the tensioning pedal 132', and the connecting pin 135' penetrates through the receiving cylinder 133' and the braking block 134'. The locking pedal 131' is hinged to the receiving cylinder 133' and the tensioning pedal 132', thereby forming a three-link mechanism. On the one hand, when the locking pedal 131' gradually rotates towards the direction close to the braking block 134', the braking block 134' gradually slides along the guiding groove 1331' and extends out of the receiving cylinder 133'. The tensioning pedal 132' rotates around the central axis of the connecting pin 135' towards the direction away from the braking block 134' until it passes the dead point. The braking block 134' supports the base 110', and the universal wheels 120' are all stationary relative to the ground. The foot brake assembly 130' is in a braking state. In this way, relying on the frictional resistance between the braking block 134' and the ground, the vehicle measuring device 900' can be prevented from moving randomly, playing a role in braking. On the other hand, press the tensioning pedal 132' and make the tensioning pedal 132' gradually approach the receiving cylinder 133', so that the braking member 134' passes the dead point position of the three-link mechanism. The locking pedal 131' rotates around the central axis of the connecting pin 135' towards the direction away from the braking block 134', so that the braking member 134' retracts into the receiving cylinder 133'. The locking pedal 131' and the braking block 134' are both reset, and the foot brake assembly 130' is in a non-braking state. At this time, the vehicle measuring device 900 can be pushed randomly.

[0219] It should be understood that when the foot brake assembly 130' is in a non-braking state, there is a gap between the braking member 134' and the ground, so that the user can push the vehicle measuring device 900' randomly.

[0220] It should be noted here that the shape of the braking block 134' can be a straight rod shape or other shapes, as long as the braking member can abut against the ground when the foot brake assembly 130 is in a braking state. In this embodiment, the shape of the braking block 134' is an inverted "T" shape, that is, the braking block 134' includes a handle part (not marked) and a flat part (not marked) connected to the handle part. The flat part can contact the ground relatively large, reducing the impact of the vehicle measuring device 900 on the ground and avoiding damage to the ground caused by excessive weight.

[0221] In some embodiments, the adjusting device further includes a fine-tuning mechanism 800, and the fine-tuning mechanism 800 is installed between the adjusting mechanism 380 and the column module 200. That is, one end of the fine-tuning mechanism 800 is connected to the column module 200, and the other end of the fine-tuning mechanism 800 is connected to the adjusting mechanism 380. At this time, the adjusting mechanism 380 is used to adjust the position of the cross beam 310 relative to the column module 200, and the fine-tuning mechanism 800 is used to adjust the pitch angle and roll angle formed by the displacement of the cross beam 31 relative to the column module 200. The pitch angle is the angle at which the cross beam 31 rotates around a first axis along the horizontal direction, and the roll angle is the angle at which the cross beam 31 rotates around a second axis. The second axis is perpendicular to the first axis and the vertical direction.

[0222] The adjusting mechanism 380 in this embodiment has the following differences from the above embodiment:

[0223] Please combine Figures 38 - 41 In addition, the adjusting component 384 further includes a third mounting block 3841', and the third mounting block 3841' is rotatably installed on the first connecting plate 381. The first driving rod 3842 is connected to the third mounting block 3841'. Wherein, there is a third gap between the third mounting block 3841' and the end face of the first connecting plate 381 facing the second connecting plate 382. Specifically, two third protrusions 3811 are provided on the end face of the first connecting plate 381 facing the second connecting plate 382, and third limiting holes (not labeled) are provided on both of the two third protrusions 3811. Third extension blocks (not labeled) are provided at opposite ends of the third mounting block 3841'. One third extension block (not labeled) is inserted into the third limiting hole of one third protrusion 3811, and the other extension block 3812 is inserted into the third limiting hole of the other third protrusion 3811. In this way, the third mounting block 3841' can rotate relative to the two third protrusions 3811.

[0224] When driving the first driving rod 3842 to drive one end of the first connecting plate 381 to move away from the support plate 383, under the action of the rotating shaft 3841, the other end of the first connecting plate 381 will move towards the support plate 383 and squeeze the elastic member 3843, so that the first connecting plate 381 drives the cross beam 31 to rotate around the central axis of the column module 200.

[0225] It is understandable that a third gap is provided between the third mounting block 3841' and the first connecting plate 381, which can improve the smoothness of the first driving rod 3842 driving the first connecting plate 381, prevent the first driving rod 3842 from jamming during the process of driving the first connecting plate 381 to rotate around the central axis of the rotating shaft 3841, and enhance the stability of the adjusting mechanism 380.

[0226] In some embodiments, the adjusting assembly 384 further includes a fourth mounting block 3842'. The fourth mounting block 3842' is rotatably mounted on the support plate 383. Wherein, the fourth mounting block 3842' is provided with an internal thread hole (not labeled), the outer surface of the first driving rod 3842 has a thread, and the first driving rod 3842 is threadedly connected to the fourth mounting block 3842'. In this embodiment, the support plate 383 is provided with two fourth convex blocks 3833, and both of the two fourth convex blocks 3833 are provided with fourth limiting holes (not labeled). The opposite ends of the fourth mounting block 3842' are provided with fourth extension blocks (not labeled), and one of the fourth extension blocks is correspondingly inserted into one of the fourth limiting holes, so that the fourth mounting block 3842' can rotate relative to the support plate 383, so that the fourth mounting block 3842' drives the first driving rod 3842 to rotate to adapt to the rotation of the third mounting block 3841'.

[0227] In some embodiments, a bearing 3843' and a bearing fixing seat 3844' for fixing the bearing 3843' are installed at one end of the first driving rod 3842 close to the third mounting block 3841', and the bearing fixing seat 3844' is detachably installed on the third mounting block 3841'.

[0228] When the first driving rod 3842 is screwed, the first driving rod 3842 approaches or moves away from the first connecting plate 381. The thread of the internal thread hole cooperates with the thread on the surface of the first driving rod 3842, and the position of the first connecting plate 381 can be finely adjusted.

[0229] In this embodiment, by providing the adjusting mechanism 380, the vehicle measuring device 900 can adjust the position of the cross beam 31 relative to the column module 200 to meet the position requirements of the cross beam 31 during ADAS calibration or four-wheel alignment.

[0230] Such as Figures 42 - 45As shown, in some embodiments, the fine-tuning mechanism 800 includes a first fine-tuning plate 810, a second fine-tuning plate 820, and a first fine-tuning component 830. One end of the first fine-tuning plate 810 is rotatably mounted on the adjusting mechanism 380. The other end of the first fine-tuning plate 810 is connected to one end of the second fine-tuning plate 820. The other end of the second fine-tuning plate 820 is connected to the lifting plate 223. The first fine-tuning component 830 is mounted on the first fine-tuning plate 810, and the first fine-tuning component 830 is used to rotate the adjusting mechanism 380 relative to the first fine-tuning plate 810.

[0231] The first fine-tuning plate 810 includes a first base plate 811, a first side plate 812, a second side plate 813, a retaining piece 814, and a mounting strip 815. Two ends of the first base plate 811 are respectively connected to the first side plate 812 and the second side plate 813. Both the first side plate 812 and the second side plate 813 are connected to the retaining piece 814. The mounting strip 815 is mounted on the first base plate 811. Among them, both the first side plate 812 and the second side plate 813 protrude from an end face of the first base plate 811 in the same direction, so that the first side plate 812, the second side plate 813, and the first base plate 811 enclose a chamber (not labeled). The retaining piece 814 can block part of the chamber. In this embodiment, the first base plate 811 includes a main base plate portion 8111, a first extension portion 8112 extending from one end of the main base plate portion 8111, and a second extension portion 8113. The area between the first extension portion 8112 and the second extension portion 8113 is hollowed out. On the side of both the first side plate 812 and the second side plate 813 facing the adjusting mechanism 380, shoulder portions (not labeled) are provided. One end of the mounting strip 815 is connected to the main base plate portion 8111, and the other end is arranged in a direction away from the main base plate portion 8111. Among them, the mounting strip 815 includes a mounting strip main body 8151, a first convex portion 8152, and a second convex portion 8153. Both the first convex portion 8152 and the second convex portion 8153 are connected to the mounting strip main body 8151.

[0232] The second fine-tuning plate 820 includes a second substrate 821, a third side plate 822, and a fourth side plate 823. The third side plate 822 and the fourth side plate 823 are respectively connected to opposite ends of the second substrate 821. One end face of the second substrate 821 is connected to the first substrate 811, and the other end face of the second substrate 822 is connected to the lifting plate 223. Wherein, the ends of the third side plate 822 and the fourth side plate 823 both have a first slope 8221, a second slope 8222, and a transition portion 8223. The transition portion 8223 is located between the first slope 8221 and the second slope 8222. Among them, the slope length of the first slope 8221 is greater than the slope length of the second slope 8222.

[0233] The first fine-tuning assembly 830 includes a rotating bearing 831, a first fine-tuning screw 832, a driving block 833, and a first mounting block 834. The rotating bearing 831 is installed on the first substrate 811. The rotating bearing 831 is connected to the adjusting mechanism 380. The first mounting block 834 is installed on the first fine-tuning plate 810. The first mounting block 834 is provided with a first screw hole (not labeled). The first fine-tuning screw 832 is screwed to the first mounting block 834 through the first screw hole. One end of the driving block 833 is connected to the second connecting plate 382, and the other end of the driving block 833 at least extends to intersect with the central axis of the first fine-tuning screw 832. Thus, when the first fine-tuning screw 832 is gradually screwed and the other end of the first fine-tuning screw 832 gradually pushes the driving block 833 to move, one end of the driving block 833 will drive the adjusting mechanism 380 to rotate around the central axis of the rotating bearing 831 in a first preset direction. When the first fine-tuning screw 832 is screwed in the reverse direction, the first fine-tuning screw 832 moves away from the driving block 833 so that the driving block 833 has a margin of movement when manually resetting the adjusting mechanism 380.

[0234] In some embodiments, the first fine-tuning assembly 830 further includes a second mounting block 835. The second mounting block 835 is installed at the other end of the driving block 833. The first fine-tuning screw 832 passes through the first mounting block 834 and is then connected to the second mounting block 835. Thus, when the first fine-tuning screw 832 is screwed in the reverse direction and the other end of the first fine-tuning screw 832 gradually pushes the driving block 833 to move, the first fine-tuning screw 832 will drive the driving block 833 to rotate so that the driving block 833 drives the adjusting mechanism 380 to rotate around the central axis of the rotating bearing 831 in a second preset direction. The first preset direction is opposite to the second preset direction. For example, if the first preset direction is the clockwise direction, then the second preset direction is the counterclockwise direction.

[0235] Further, there is a first gap between the first mounting block 834 and the first side plate 812, and a second gap between the second mounting block 835 and the driving block 833, so that the first mounting block 834 can rotate relative to the first side plate 812, and the second mounting block 835 can rotate relative to the driving block 833. It can be understood that the first gap and the second gap respectively provide a movement margin for the rotation of the first mounting block 834 and the second mounting block 835, so as to prevent the driving block 833 from jamming when using the first fine-tuning screw 832 to adjust the position of the adjusting mechanism 380 relative to the first fine-tuning plate 810.

[0236] Specifically, the first side plate 812 is provided with two first protrusions 8121, the first protrusions 8121 are provided with first limiting holes (not labeled), both opposite ends of the first mounting block 834 are provided with first extension blocks (not labeled), and one of the first extension blocks is correspondingly inserted into one of the first limiting holes to realize the installation of the first mounting block 834 on the first side plate 812. Similarly, the other end of the driving block 833 is provided with two second protrusions 8331, each of the second protrusions 8331 is provided with a second limiting hole (not labeled), both opposite ends of the second mounting block 835 are provided with second extension blocks (not labeled), and one of the second extension blocks is inserted into one of the second limiting holes, so that the second mounting block 835 can rotate relative to the driving block 833.

[0237] In some embodiments, the first fine-tuning assembly 830 further includes a bearing seat 836 and a bearing member 837. The bearing seat 836 is installed on the second mounting block 835, the bearing member 837 is embedded in the bearing seat 836, and the bearing member 837 is sleeved on the first fine-tuning screw 832.

[0238] During actual use, by turning the first fine-tuning screw 832, and under the action of the rotating bearing 831, the driving block 833 can be driven to move close to one end of the first fine-tuning screw 832, and the other end of the driving block 833 will drive the second connecting plate 382 to rotate around the central axis of the rotating bearing 831, so as to adjust the position of the second connecting plate 382 relative to the first fine-tuning plate 810, which is convenient and fast to adjust.

[0239] In some embodiments, the fine-tuning mechanism 800 further includes a second fine-tuning assembly 840. The fine-tuning assembly 840 is installed on the first fine-tuning plate 810 and the second fine-tuning plate 820, and the second fine-tuning assembly 840 is used to adjust the included angle between the first fine-tuning plate 810 and the second fine-tuning plate 820.

[0240] The second fine-tuning component 840 includes a power rod 841, a first connection block 842, a second connection block 843, a connecting rod 844, and a hinge 845. The power rod 841 is rotatably mounted on the first fine-tuning plate 810. The first connection block 842 is connected to the power rod 841. One end of the connecting rod 844 is connected to the first connection block 842, and the other end of the connecting rod 844 is connected to the second connection block 843. The second connection block 843 is connected to the second fine-tuning plate 820. Among them, the surface of the power rod 841 has threads, and the first connection block 842 is provided with an internal threaded hole (not marked) with internal threads. The power rod 841 is threadedly connected to the first connection block 842. When the power rod 841 rotates in place relative to the first fine-tuning plate 810, under the action of the threads on the surface of the power rod 841, the first connection block 842 can be driven to move along the axial direction of the power rod 841, so as to drive the connecting rod 844 to swing, thereby realizing the unfolding or closing of the first fine-tuning plate 810 relative to the second fine-tuning plate 820. In this embodiment, the hinge 845 is located between the first fine-tuning plate 810 and the second fine-tuning plate 820, and the hinge 845 is set away from the first fine-tuning screw 832 and close to the transition slope 8223. If along the central axis direction of the column module 200, the first slope 8221 gradually flattens in the direction away from the ground, and the second slope 8222 gradually flattens in the direction close to the ground.

[0241] It should be understood that the installation of the power rod 841 can be achieved by setting a threaded block structure on the first fine-tuning plate 810. Of course, other methods can also be used to install the power rod 841. For example, the power rod 841 can be directly screwed to the first convex portion 8152 and the second convex portion 8153. At this time, both the first convex portion 8152 and the second convex portion 8153 are provided with threaded holes (not marked), and a part of the power rod 841 extends out of the first fine-tuning plate 810 for the user to directly turn.

[0242] In some other embodiments, the second fine-tuning component 840 further includes a second fine-tuning screw 845, a first bevel gear 846, a second bevel gear 847, and a limit bearing 848. One end of the second fine-tuning screw 845 is connected to the first bevel gear 846, and the other end of the second fine-tuning screw 845 passes through the first fine-tuning plate 810 and is exposed outside. The second bevel gear 847 is mounted on one end of the power rod 841. The second bevel gear 847 meshes with the first bevel gear 846. The other end of the power rod 841 is sleeved with the limit bearing 848, and the limit bearing 848 is fixedly installed on the second convex portion 8153.

[0243] Thus, when turning the second fine-tuning screw 845 to drive the first bevel gear 846 to rotate, under the action of the limit bearing 848, the second bevel gear 847 drives the power rod 841 to rotate at the original installation position, and the first connecting block 842 rotates along the axial direction of the power rod 841, so as to drive the connecting rod 844 to push the first fine-tuning plate 810 to rotate relative to the second fine-tuning plate 820, thereby adjusting the included angle between the first fine-tuning plate 810 and the second fine-tuning plate 820. It should be noted here that taking the center line of the first fine-tuning plate 810 as O1 and the center line of the second fine-tuning plate 820 as O2, as Figure 46 shown, the included angle between the first fine-tuning plate 810 and the second fine-tuning plate 820 refers to the included angle between O1 and O2. Turning the second fine-tuning screw 845 can adjust the included angle between O1 and O2, thereby adjusting the relative positions of the first fine-tuning plate 810 and the second fine-tuning plate 820. In this embodiment, the range of the included angle between the first fine-tuning plate 810 and the second fine-tuning plate 820 that can be adjusted by the second fine-tuning screw 845 is [0°, 3°].

[0244] In some embodiments, the second fine-tuning assembly 840 further includes a guide slider 849 and a guide bar 8410. The guide bar 8410 is installed on the installation bar main body 8151, the guide slider 849 is slidably installed on the guide bar 8410, and the guide slider 849 is connected to the first connecting block 842. When the first connecting block 842 moves under the action of the power rod 841, under the combined action of the guide bar 8410 and the guide slider 849, the first connecting block 842 will stably slide along the axial direction of the power rod 841.

[0245] Please refer to Figures 47 - 48 , for the convenience of the reader to understand that the adjustment mechanism adjusts the pitch angle and roll angle of the cross beam 31 relative to the column module 200, taking the first axis as Figure 47 or Figure 48The X-axis in it is taken as the Y-axis in the figure with the second axis, and the vertical direction is the Z-axis shown in the figure. When the user turns the first fine-tuning screw 832, the entire adjusting mechanism 380 will rotate along the Y-axis in the first plane. The first plane is the plane formed by the intersection of the X-axis and the Z-axis, so as to adjust the tilt angle of the cross beam 31 relative to the column module 200. When turning the second fine-tuning screw 845, the first fine-tuning plate 810 will rotate around the X-axis in the second plane. The second plane is the plane formed by the intersection of the Y-axis and the Z-axis, so as to realize that the first fine-tuning plate 810 slightly unfolds or closes relative to the second fine-tuning plate 820, thereby realizing the adjustment of the pitch angle of the cross beam 31 relative to the column module 200. By turning the first driving rod 3842, the rotation angle of the cross beam relative to the column module can be adjusted. The rotation angle is the angle at which the cross beam 31 rotates in the plane formed by the intersection of the X-axis and the Y-axis.

[0246] Figure 47 The axis L shown in it is the central axis direction of the cross beam 31 after the tilt angle is adjusted under the action of the fine-tuning mechanism 800. At this time, the included angle between the axis L and the X-axis is the adjusted tilt angle. In this embodiment, the first axis is the central axis of the rotating shaft of the hinge 845, the second axis is the central axis of the rotating bearing 831, and the vertical direction is the axis of the column module perpendicular to the base module 100'.

[0247] By setting the fine-tuning mechanism 800, it is convenient for the user to turn the first fine-tuning screw 832 and / or the second fine-tuning screw 845 according to the actual scenario requirements, so as to realize the adjustment of the position of the adjusting mechanism 380 relative to the column module 200, and further realize the adjustment of the position of the cross beam 31. The operation is fast and convenient.

[0248] The vehicle measuring device 900' provided by the embodiment of the present invention includes a base module 100', a column module 200 and a cross beam module 300. The column module 200 is installed on the base module 100'. The cross beam module 200 includes a cross beam 31, an adjusting mechanism 380 and a fine-tuning mechanism 800. One end of the fine-tuning mechanism 800 is installed on the column module 200, the other end of the fine-tuning mechanism 800 is installed with the adjusting mechanism 380, the cross beam 31 is installed on the adjusting mechanism 380, the adjusting mechanism 380 is used to adjust the position of the cross beam 31 relative to the column module 200, and the fine-tuning mechanism 800 is used to adjust the position of the adjusting mechanism 380 relative to the column module 200. Through the above structure, during the adjustment process, the user only needs to adjust the position of the cross beam 31 through the fine-tuning mechanism 800 and the adjusting mechanism 380, and there is no need to frequently bend down to adjust the base module to adjust the position of the cross beam, and the operation is relatively convenient.

[0249] The above are only the embodiments of the present invention, and do not thus limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall similarly be included within the patent protection scope of the present invention.
