[0032] As Figs. 1 to 3As shown, the four-wheel positioning calibration device 100 is installed on the lifting machine 200 of the four-wheel positioning instrument for bearing the vehicle, and is used for calibrating the four-wheel positioning measuring device 300 on the lifting machine 200 of the bearing vehicle. Specifically, the four-wheel positioning instrument comprises four four-wheel positioning measuring devices 300 and two four-wheel positioning calibration devices 100. The two four-wheel positioning measuring devices 300 are located on one side of the vehicle, and the four-wheel positioning calibration device 100 is located between the two four-wheel positioning measuring devices 300 on the side. The two four-wheel positioning measuring devices 300 are located on the other side of the vehicle, and the four-wheel positioning calibration device 100 is located between the two four-wheel positioning measuring devices 300 on the side. The two four-wheel positioning measuring devices 300 located on the two sides of the vehicle are oppositely arranged. The two four-wheel positioning measuring devices 300 located on the same side are used for shooting the image of the four-wheel positioning measuring device 300, and finally calibrating the position of itself. Similarly, the two four-wheel positioning calibration devices 100 located on the opposite sides are used for shooting the image of the four-wheel positioning calibration device 100 on the opposite side, and finally calibrating the position of itself. The following is described through the specific implementation manner:

[0033] The four-wheel positioning calibration device 100 comprises:

[0034] The calibration seat body 1, the calibration component 2, the camera device 3 and the camera device connecting piece 4. The calibration seat body 1 is defined with at least two calibration directions parallel to the calibration seat body 1. The calibration component 2 is arranged on the calibration seat body 1 and located on the calibration direction. One end of the camera device connecting piece 4 is connected with the calibration seat body 1, and the other end of the camera device connecting piece 4 is connected with the camera device 3, so that the projection of the camera device 3 and the calibration component 2 along any calibration direction does not coincide with each other.

[0035] Here, it can be understood that the calibration seat body 1 is used for supporting the calibration component 2; the calibration component 2 is used for providing a calibration image to calibrate the position of the four-wheel positioning measuring device 300 and the four-wheel positioning calibration device 100 on the opposite side; the camera device 3 is used for acquiring the image of the four-wheel positioning calibration device 100 on the opposite side; and the camera device connecting piece 4 is used for connecting the camera device 3 and the calibration seat body 1.

[0036] Specifically, the calibration component 2 is arranged on the calibration seat body 1, and the calibration seat body 1 is spaced apart from the four-wheel alignment measuring device 300 by a preset distance, so that the four-wheel alignment measuring device 300 can obtain the image of the calibration component 2 on the calibration seat body 1, and the four-wheel alignment measuring device 300 can also calculate the coordinate value according to the distance between the four-wheel alignment measuring device 300 and the calibration seat body 1; the calibration seat body 1 defines at least two calibration directions, and the calibration direction is parallel to the surface of the calibration seat body 1 for supporting the calibration component 2; the four-wheel alignment measuring device 300 and the four-wheel alignment calibration device are located in one of the calibration directions, that is, the four-wheel alignment measuring device 300 can obtain the image of the four-wheel alignment calibration device in the calibration direction, and the image is a calibration image, that is, the four-wheel alignment measuring device 300 can obtain the image of the calibration component 2 along the calibration direction to analyze the position of the four-wheel alignment measuring device 300 and calibrate the position of the four-wheel alignment measuring device 300; similarly, the opposite four-wheel alignment calibration device 100 and the four-wheel alignment calibration device are located in the other calibration direction, that is, the opposite four-wheel alignment calibration device 100 can obtain the image of the four-wheel alignment calibration device in the calibration direction, and the image is a calibration image, that is, the opposite four-wheel alignment calibration device 100 can obtain the image of the calibration component 2 along the calibration direction to analyze the position of the opposite four-wheel alignment calibration device 100 and calibrate the position of the opposite four-wheel alignment calibration device 100.

[0037] By adopting the above technical scheme:

[0038] The plurality of four-wheel alignment measuring devices 300 of the four-wheel alignment instrument can obtain the calibration images of the calibration component 2 from different calibration directions, so that the plurality of four-wheel alignment measuring devices 300 can perform calibration work by sharing one four-wheel alignment calibration device, thereby reducing the demand for four-wheel alignment calibration devices, improving the calibration efficiency, and at the same time, the calibration seat body 1 forming at least two calibration directions can also improve the accuracy of the calibration result;

[0039] One end of the camera connecting piece 4 is connected to the calibration seat body 1, and the other end of the camera connecting piece 4 is connected to the camera 3, so that the projection of the camera 3 and the calibration component 2 along any calibration direction does not coincide with each other, so that the camera 3 can avoid the calibration component 2 and reduce the possibility of the camera 3 blocking the calibration component 2; the application of the camera connecting piece 4 in the four-wheel alignment instrument can reduce the possibility of errors in the calibration result and improve the accuracy of the detection result of the four-wheel alignment instrument.

[0040] In one embodiment, one end of the camera connecting piece 4 is connected to the side or bottom of the calibration seat body 1, and the other end of the camera connecting piece 4 is connected to the side or bottom of the camera 3.

[0041] Here, it can be understood that the camera connecting piece 4 and the calibration seat body 1 and the camera connecting part include a side and a bottom, of course, the camera 3 can also be movably connected or slidingly connected with the camera connecting piece 4 to realize the function of adjusting the position, for example, adjusting the height of the camera 3 to adapt to different camera heights.

[0042] By adopting the above technical scheme, the camera connecting piece 4 and the calibration seat body 1 and the camera 3 have multiple connection positions, and the fixed connection mode has high flexibility; at the same time, the camera 3 also has the advantage of high adjustment flexibility.

[0045] By adopting the above technical scheme, since the weight of the power supply piece is large, the calibration seat body 1 is stacked on the fixing device 5, so that the center of gravity of the four-wheel alignment calibration device 100 is concentrated and arranged close to the fixing piece 51, thereby reducing the possibility of the four-wheel alignment calibration device 100 overturning.

[0046] In one embodiment, the fixing piece 51 is a magnetic piece capable of being magnetically attached to the lifting machine 200 of the vehicle.

[0047] Here, it can be understood that the lifting machine 200 of the vehicle has a part made of a magnetic material, for example, the rack of the lifting machine 200 is made of a magnetic metal, so that the magnetic piece can be magnetically attached to the lifting machine 200 of the vehicle.

[0048] By adopting the above technical scheme, the four-wheel alignment calibration device 100 is fixed on the lifting machine 200 by the magnetic attachment mode, which is beneficial to the disassembly and assembly of the four-wheel alignment calibration device 100, and is also beneficial to the adjustment of the position of the four-wheel alignment calibration device 100.

[0049] In one embodiment, the power supply piece is located at a part of the fixing device 5 close to the fixing piece 51.

[0050] Here, it can be understood that, since the four-wheel alignment calibration device 100 is fixed on the lifting machine 200 in a magnetic attraction manner, the overall weight of the four-wheel alignment calibration device 100 greatly affects the magnetic attraction fixing effect; the power supply member with relatively large weight is arranged close to the fixing member 51, so that the center of gravity of the four-wheel alignment calibration device 100 is close to the fixing member 51, which is beneficial to improving the magnetic attraction fixing effect of the fixing member 51.

[0051] By adopting the above technical solution, the stability of the four-wheel alignment calibration device 100 fixed on the lifting machine 200 is improved.
