[0041] The ADAS calibration device can assist in obtaining the parameters of sensors (such as cameras, radars, etc. on the vehicle), and then adjust the sensors to the best state, so that they can more accurately perceive the environment around the vehicle.

[0042] The current ADAS calibration device needs to measure the distance between itself and the vehicle when in use, and usually uses a range finder to measure the distance, but the range finder can only cover a limited range, and cannot measure when the ranging target deviates from the center line of the range finder far away.

[0043] In order to alleviate and solve the above technical problems, the present application provides a vehicle calibration device, which is provided with a ranging mechanism 35 in the middle of the cross beam assembly 40, which can cover the area directly opposite the middle of the cross beam assembly 40, and is provided with a shooting camera 50 at both ends of the cross beam assembly 40, which can cover the area directly opposite both ends of the cross beam assembly 40, greatly reducing the ranging blind area of the vehicle calibration device.

[0046] The base assembly 10 is generally used for being placed on the ground, and is used for supporting the column assembly 20, facilitating movement of a vehicle four-wheel alignment device, and making the vehicle calibration device more stable when being placed.

[0047] The column assembly 20 is arranged on the base assembly 10, and the column assembly 20 is generally a vertically arranged strip-shaped structure, and is used for supporting the crossbeam assembly 40, so that the crossbeam assembly 40 is at a set height.

[0048] The crossbeam assembly 40 is slidingly arranged on the column assembly 20, that is, the height of the crossbeam assembly 40 is variable, and the crossbeam assembly 40 moves up and down relative to the column assembly 20. When the ADAS calibration device calibrates a vehicle, the height of the crossbeam assembly 40 can be adjusted through the lifting of the crossbeam assembly 40, and then the height of the calibration target on the crossbeam assembly 40 is adjusted. The crossbeam assembly 40 is provided with the hanging assembly 460, the hanging assembly 460 is used for hanging the calibration target, and the calibration target on the crossbeam assembly 40 is detected by a sensor (a camera, a radar and the like) on the vehicle, so as to assist in detecting parameters of the sensor.

When the vehicle calibration device works, the shooting camera 50 can take a photo of a distance measuring target, and detect the distance between the calibration device and the distance measuring target. The shooting camera 50 is arranged on the crossbeam assembly 40, and moves synchronously when the crossbeam assembly 40 moves. The number of the shooting cameras 50 is two, and the two shooting cameras 50 are arranged at two ends of the crossbeam assembly 40 respectively.

In this way, through the combination of the shooting camera 50 and the distance measuring mechanism 35, most of the test area can be covered, and the blind area of distance measurement is reduced.

[0052] In some embodiments of the utility model, please refer toFigure 3 The hanging assembly 460 comprises a first hanging structure 46 which is clamped to the cross beam assembly 40 and can slide relative to the cross beam assembly 40, the first hanging structure 46 comprises a hanging plate 461 and a sliding clamping structure 463 fixed to the hanging plate 461, and a hanging hole 4611 for hanging the calibration piece is formed in the hanging plate 461.

[0053] The first hanging structure 46 is clamped to the cross beam assembly 40 and can slide relative to the cross beam assembly 40 in use, and the sliding direction of the first hanging structure 46 is the length direction of the cross beam assembly 40, so that the horizontal position of the first hanging structure 46 can be changed, and the horizontal position of the calibration piece hung on the first hanging structure 46 can also be changed.

Specifically, the back of the calibration piece is generally provided with a hanging protrusion which is inserted into the hanging hole 4611, so that the calibration piece can be stably hung on the hanging plate 461.

[0054] By arranging the sliding clamping structure 463 on the first hanging structure 46, the first hanging structure 46 can slide relative to the cross beam assembly 40, so that the horizontal position of the first hanging structure 46 can be adjusted, and the first hanging structure 46 can be stably clamped to the cross beam assembly 40, and the first hanging structure 46 can also be removed from the cross beam assembly 40 according to requirements.

[0055] In some embodiments, referring to Figure 3 The hanging hole 4611 is arranged on the top side of the hanging plate 461 and is recessed downward from the top side of the hanging plate 461. The hanging protrusion has a neck portion with a smaller diameter than other positions, and the neck portion of the hanging protrusion is inserted into the hanging hole 4611.

[0056] In some embodiments, referring to Figure 3 The number of the hanging holes 4611 is multiple, and the multiple hanging holes 4611 are arranged in sequence along the length direction of the cross beam assembly 40, so that the calibration piece can be more stably hung on the hanging plate 461.

[0057] In some embodiments of the utility model, referring to Figure 2 and Figure 5 The hanging assembly 460 further comprises a supporting structure 48, one end of the supporting structure 48 is rotationally connected to the cross beam assembly 40, the other end of the supporting structure 48 has a supporting protrusion portion 481 for supporting the calibration piece, the first clamping structure 411 is fixed on the cross beam assembly 40, the second clamping structure 482 is arranged on the supporting structure 48, and the first clamping structure 411 and the second clamping structure 482 are clamped to each other, so that the supporting structure 48 is arranged close to the cross beam assembly 40.

When the first clamping structure 411 and the second clamping structure 482 are clamped with each other, the support structure 48 is rotated relative to the beam assembly 40 to be close to the beam assembly 40, and the support structure 48 is in the storage state. When the support structure 48 is perpendicular to the beam assembly 40, the support protrusion 481 of the support structure 48 is in abutment with the bottom side of the calibration object, and the support structure 48 is in the use state.

[0059] The support structure 48 can support the bottom plate of the calibration object, so that the calibration object is more stable and the shaking of the calibration object is reduced. Moreover, the support structure 48 can be rotated to the storage state and clamped with the beam assembly 40, that is, when the support structure 48 is not needed, it can be rotated and stored, and other test work of the calibration device is not affected.

[0060] In some embodiments, referring to Figure 2 and Figure 5 , the support protrusion 481 can support the bottom of the calibration object and can be held by the user.

[0061] Optionally, the support protrusion 481 is a cylindrical structure, a cuboid structure, or the like.

[0062] In some embodiments, a positioning groove is formed in the surface of the support protrusion 481. When the support structure 48 is in the use state, the edge of the bottom of the calibration object is inserted into the inside of the positioning groove, so that the calibration object can be kept in the vertical state to prevent the calibration object from having an unintended pitch attitude.

[0065] Optionally, the protruding structure can be spherical or disc-shaped.

[0067] The second hanging structure 47 is used for limiting the side of the calibration element. The second hanging structure 47 can be clamped on the cross beam assembly 40 or can slide relative to the cross beam assembly 40, that is, the position of the second hanging structure 47 on the cross beam assembly 40 can be adjusted. The second hanging structure 47 comprises the limiting plate 471 and the sliding clamping structure 463, the sliding clamping structure 463 is arranged so that the whole second hanging structure 47 can be slidably clamped on the cross beam assembly 40, and the limiting groove 4711 is formed in the limiting plate 471, in use of the second hanging structure 47, the side edge of the calibration element extends into the limiting groove 4711.

[0068] When the calibration element to be hung is large, the calibration element is easy to shake, and the hanging of the calibration element by the first hanging structure 46 is not stable, the left and right sides of the calibration element are limited by the two second hanging structures 47 respectively, so that the calibration element is more stable.

[0069] In some embodiments, the limiting groove 4711 is arranged along the side wall of the limiting plate 471, so that the limiting groove 4711 extends to the upper and lower sides of the limiting plate 471, and the limiting plate 471 can be clamped at any position of the side wall of the calibration element.

[0072] For the convenience of description, the hanging plate 461 and the limiting plate 471 can be collectively referred to as a fixed structure, and the sliding clamping structure 463 is fixed to the fixed structure. Specifically, the fixed seat 4633 is fixed to the hanging plate 461 in the first hanging structure 46, and the fixed seat 4633 is fixed to the limiting plate 471 in the second hanging structure 47. When the push rod 4636 is pushed, the pushing part 46361 on the push rod 4636 pushes the pressing part 4632, so that the pressing part 4632 is separated from the cross beam assembly 40, the hanging structure is unlocked with the cross beam assembly 40, and the first hanging structure 46 and the second hanging structure 47 are pushed to the predetermined position, and then the push rod 4636 is restored to the initial position.

[0073] The setting of the pressing elastic part 4634 enables the pressing part 4632 to be pressed against the cross beam assembly 40, and the compression amount of the pressing elastic part 4634 can be controlled through the movement of the push rod 4636, so that the locking and unlocking of the hanging structure can be quickly controlled.

[0074] In some embodiments, referring to Figure 3 and Figure 4 The pressing part 4632 has a friction surface for pressing the cross beam assembly 40, and the static friction between the friction surface and the cross beam assembly 40 is large, so that the first hanging structure 46 and the second hanging structure 47 can be more stably clamped on the cross beam assembly 40.

In this way, the pushing part 46361 has a large size in the length direction of the cross beam assembly 40, and the push rod 4636 can be swung left or right to push the pressing elastic part 4634. Moreover, when the external force is lost, the push rod 4636 will automatically return to the normal position and be clamped on the cross beam assembly 40, so as to prevent the hanging structure from falling off the cross beam assembly 40.

[0096] The first horizontal moving mechanism 11, the second horizontal moving mechanism 12 and the rotating mechanism 13 are sequentially drivingly connected, 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.

The angle adjusting mechanism 30 between the column assembly 20 and the beam assembly 40 only needs to adjust the pitch angle and the roll angle of the beam assembly 40, so that the structure of the angle adjusting mechanism 30 is simple, which is beneficial to the miniaturization of the angle adjusting mechanism 30, but occupies more space between the column assembly 20 and the beam assembly 40, and fully utilizes the interior space of the base assembly 10.

[0098] In some embodiments, referring to Figure 12 The first horizontal moving mechanism 11 is a second screw assembly, which includes a second motor, a second screw rod, a second nut block and a second sliding rail.

The top of the base shell 142 is provided with a movable window, and the column base 141 blocks the movable window. In this way, during the movement of the column assembly 20 relative to the base shell 142, the movable window is always kept in a blocked state, preventing the mechanisms inside the base assembly 10 from being exposed.

During the rotation of the second crossbeam 42 relative to the first crossbeam 41, the first elastic member 451 can provide thrust for the rotation of the second crossbeam 42, and can also make the rotation of the second crossbeam 42 smoother and more stable.

[0107] The second crossbeam 42 can rotate relative to the first crossbeam 41, allowing the crossbeam assembly 40 to be folded and stored, facilitating the production, transportation, and storage of the crossbeam assembly 40.

When it is needed to store the cross beam assembly 40, two fingers press the two first button portions 4342 at the same time, so that the two first clamping portions 4341 are separated from the second clamping portion 4321 respectively, and then the second cross beam 42 is rotated to the folding state of the cross beam assembly 40.
