[0056] The height of the cross beam assembly 40 is variable and can be lifted and lowered relative to the column assembly 20. When the vehicle is subjected to the ADAS calibration or the four-wheel alignment, the height of the cross beam assembly 40 can be adjusted by lifting and lowering the cross beam assembly 40, and then the height of the calibration piece on the cross beam assembly 40 is adjusted. The cross beam assembly 40 is provided with a hanging assembly 460, the hanging assembly 460 is used for hanging the calibration piece, and the calibration piece on the cross beam assembly 40 is used for being detected by the sensor (a camera, a radar, etc.) on the vehicle to assist in detecting the parameters of the sensor.

When the vehicle measuring device works, the shooting camera 50 can be used for shooting the ranging target to detect the distance between the vehicle measuring device and the ranging target, and the shooting camera 50 can also be used for shooting the target at the wheel during the four-wheel alignment.

[0058] The vehicle measuring device in the above embodiment comprises the base assembly 10, the column assembly 20, the cross beam assembly 40, the shooting camera 50 and the hanging assembly 460. The shooting camera 50 can be used for shooting the target on the wheel hub during the four-wheel alignment to obtain the parameters of the wheel, that is, the four-wheel alignment can be performed. The shooting camera 50 can also be used for detecting the distance between the ranging target and the vehicle measuring device. The hanging assembly 460 is used for hanging the calibration piece, and the calibration piece is used for being detected by the sensor (a camera, a radar, etc.) on the vehicle to assist in detecting the parameters of the sensor, that is, the vehicle can be subjected to the ADAS calibration. Moreover, the column assembly 20 comprises the first column 21 and the second column 22 which is slidably connected to the first column 21, so that the cross beam assembly 40 has a large height moving stroke and can be simultaneously applied to the four-wheel alignment and the ADAS calibration. The column assembly 20 can be rotated relative to the base assembly 10, and then the yaw angle of the cross beam assembly 40 can be adjusted, and the structural complexity of other angle adjusting components is reduced.

[0059] In some embodiments of the utility model, please refer to Figure 2 and Figure 3The base assembly 10 further comprises a first horizontal moving mechanism 11 and a second horizontal moving mechanism 12, the movement output end of the rotating mechanism 13 is fixedly connected with the first vertical column 21, and the rotation axis of the movement output end of the rotating mechanism 13 is vertical, the first horizontal moving mechanism 11 is used for driving the second horizontal moving mechanism 12, the rotating mechanism 13 and the vertical column assembly 20 to move in a first direction, the second horizontal moving mechanism 12 is used for driving the rotating mechanism 13 and the vertical column assembly 20 to move in a second direction, the first direction and the second direction are perpendicular to each other and are both horizontal directions; and the angle adjusting mechanism 30 is arranged between the vertical column assembly 20 and the cross beam assembly 40, and the angle adjusting mechanism 30 is used for at least adjusting the pitch angle and the roll angle of the cross beam assembly 40.

[0060] The first horizontal moving mechanism 11, the second horizontal moving mechanism 12 and the rotating mechanism 13 are in transmission connection, which can be understood as that the movement output end of the first horizontal moving mechanism 11 is connected with the second horizontal moving mechanism 12, and the movement output end of the second horizontal moving mechanism 12 is connected with the rotating mechanism 13.

[0072] The rotating seat is rotated around the Y direction by rotating the first rotating hand wheel 331, thereby realizing the roll of the cross beam assembly 40. The rotating seat is rotated around the X direction by rotating the second rotating hand wheel 341, thereby realizing the pitch of the cross beam assembly 40.

[0078] In some embodiments of the utility model, please refer to Figure 6 The column assembly 20 further comprises a lifting driving element 23 fixed to the first column 21, a transmission wheel 24 which is rotatably installed on the second column 22, and a transmission chain 25 which is wound on the transmission wheel 24. The lifting driving element 23 is used for driving the lifting movement of the second column 22. One end of the transmission chain 25 is fixedly arranged, and the other end of the transmission chain 25 is connected with the cross beam assembly 40.

[0079] The lifting driving member 23 is a power component and can output linear motion, the transmission wheel 24 can rotate and is installed on the second column 22, and the lifting driving member 23 is connected with the second column 22, and the lifting driving member 23 moves under the action of the second column 22. One end of the transmission chain 25 is fixedly arranged, the other end of the transmission chain 25 is connected with the cross beam assembly 40, and the transmission chain 25 is arranged on the transmission wheel 24, and the transmission wheel 24 rotates when moving up and down. Since one end of the transmission chain 25 remains stationary, the other end (the cross beam assembly 40) of the transmission chain 25 moves with the up and down movement of the transmission wheel 24. And the displacement of the cross beam assembly 40 in the vertical direction is twice the displacement of the transmission wheel 24 in the vertical direction. Specifically, when the lifting driving member 23 works, the second column 22 moves a distance L relative to the first column 21, correspondingly, the transmission wheel 24 moves a distance L relative to the first column 21, the cross beam assembly 40 moves a distance 2L relative to the first column 21, and the cross beam assembly 40 moves a distance L relative to the second column 22. Therefore, when the length of the first column 21 is short, the cross beam assembly 40 can still realize a larger vertical stroke, and the first column 21 does not need to be arranged to be longer.

[0080] Through the cooperation of the transmission wheel 24 and the transmission chain 25, the cross beam assembly 40 has a larger moving stroke, and the length of the first column 21 is shorter, which facilitates production and transportation.

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

[0085] By arranging the second column 22 as two vertical plates 221 and a connecting plate 222, the opposite sides of the first column 21 are respectively slidably connected with the two vertical plates 221, so that the stability of the second column 22 during upward and downward movement can be improved. By arranging the guide wheel 263 between the mounting frame 26 and the vertical plate 221, the stability of the cross beam assembly 40 during upward and downward movement can be improved.

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

[0091] The bending connection between the first side wall part 2211 and the second side wall part 2212 means that an included angle is formed between the first side wall part 2211 and the second side wall part 2212, and the included angle can be a right angle, an acute angle or an obtuse angle. The angle corresponding to the L-shaped limiting corner can be a right angle, an acute angle or an obtuse angle. The limiting part 211 extends into the interior of the limiting corner and abuts against the inner wall (the wall surface of the first side wall part 2211 and the second side wall part 2212) of the limiting corner, thereby guiding the movement of the second stand 22. The circumferential direction of the guide wheel 263 between the first mounting plate 261 and the first side wall part 2211 can be provided with an annular clamping groove 2631, and when the guide wheel 263 is located in the sliding groove 2213, the opposite sides of the sliding groove 2213 abut against two opposite positions (the radial direction) of the outer circumferential wall of the clamping groove 2631.

[0092] The cooperation between the limiting corner formed by the vertical plate 221 and the limiting part 211 on the first stand 21 makes the second stand 22 more stable when moving up and down. By arranging the guide wheels 263 between the first mounting plate 261 and the first side wall part 2211 and between the second mounting plate 262 and the second side wall part 2212, firstly, the up and down movement of the mounting frame 26 relative to the second stand 22 is more stable, and secondly, the sliding friction between the mounting frame 26 and the second stand 22 is changed into rolling friction, thereby making the movement of the mounting frame 26 and the crossbeam assembly 40 more smooth.

The number of limiting parts 211 is the same as the number of limiting corners, and the number of limiting parts 211 is also four. The four corner positions of the second stand 22 are guided by the limiting parts 211 of the first stand 21, thereby making the up and down movement of the second stand 22 more stable.

[0094] Optionally, the four corners of the top plate of the first stand 21 extend to form four limiting parts 211, which are one-to-one matched with the four limiting corners.
