[0047] As shown in Figure 1 and Figure 2 The present application provides a calibration assembly, and a four-wheel alignment measuring device in a four-wheel alignment instrument is used to obtain an image of the calibration assembly to calibrate the position of the four-wheel alignment measuring device, that is, the four-wheel alignment measuring device calibrates its own position by obtaining the image of the calibration assembly. The calibration assembly of the present application can improve the accuracy of the calibration result of the four-wheel alignment measuring device, and further improve the accuracy of the tire positioning information detected by the four-wheel alignment instrument. The following will be described in detail through specific embodiments.

[0048] The calibration assembly of the present application comprises:

[0049] The calibration seat body 1 defines at least two calibration directions parallel to the calibration seat body 1, and the plurality of calibration components 2 are arranged in the calibration seat body 1, the projections of the plurality of calibration components 2 along the calibration directions do not coincide with each other, and the plurality of calibration components 2 are not at the same height of the calibration seat body 1.

[0050] Here, it can be understood that the calibration seat body 1 is used to support the calibration component 2; the calibration component 2 is used for the four-wheel alignment measuring device to obtain a calibration image, and the four-wheel alignment measuring device analyzes the calibration image to obtain coordinate information, and then calibrates its own position;

[0051] Specifically, the plurality of calibration components 2 are arranged on the calibration seat body 1, and the calibration seat body 1 is spaced apart from the four-wheel alignment measuring device by a predetermined distance, so that the four-wheel alignment measuring device can obtain the image of the plurality of calibration components 2 on the calibration seat body 1, and also facilitate the four-wheel alignment measuring device to calculate the coordinate value according to the distance between the four-wheel alignment measuring device 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 and the calibration assembly are located on the calibration direction, that is, the four-wheel alignment measuring device can obtain the image of the calibration assembly in the calibration direction, and the image is a calibration image, that is, the four-wheel alignment measuring device can obtain the image of the calibration component 2 along the calibration direction; the calibration seat body 1 defines at least two calibration directions, that is, at least two four-wheel alignment measuring devices can simultaneously obtain the image of the calibration component 2, and the projections of the plurality of calibration components 2 along the calibration directions do not coincide with each other, and the plurality of calibration components 2 are not at the same height, so that the four-wheel alignment measuring device can simultaneously obtain the images of the plurality of calibration components 2 with different heights, and the images of the plurality of calibration components 2 can provide more coordinate values and calibrate each other, thereby improving the accuracy of the calibration result, and further improving the accuracy of the tire positioning information detected by the four-wheel alignment measuring device.

[0052] It needs to be further explained that the number of calibration components 2 is positively correlated with the accuracy of the four-wheel alignment measuring device in determining its own position, that is, the more calibration components 2, the more images of the calibration components 2 obtained by the four-wheel alignment measuring device, and the more accurate the position it can analyze; Specifically, each calibration component 2 is not at the same height, and each calibration ball is not at the same position, so that the four-wheel alignment measuring device can obtain the position coordinates of different calibration components 2, so that the four-wheel alignment measuring device simultaneously obtains different data of a plurality of calibration components 2, thereby increasing the accuracy of position analysis.

[0053] By adopting the above technical scheme, the plurality of four-wheel alignment measuring devices of the four-wheel alignment tester can acquire the calibration images of the calibration components 2 from different calibration directions, so that the plurality of four-wheel alignment measuring devices can perform calibration work by sharing one calibration assembly, thereby reducing the demand for calibration assemblies and improving calibration efficiency, and meanwhile, the calibration seat body 1 is formed with at least two calibration directions, which can also improve the accuracy of the calibration result. Meanwhile, the calibration seat body 1 is provided with a plurality of calibration components 2 which are not overlapped with each other in projection in the calibration direction, so that the four-wheel alignment measuring device can acquire images of a plurality of calibration components 2 in the calibration direction, and the images of the plurality of calibration components 2 can provide more coordinate values and calibrate each other, thereby improving the accuracy of the calibration result and further improving the accuracy of the tire positioning information detected by the four-wheel alignment measuring device.

[0054] For reference Figure 3 In one embodiment, the calibration component 2 comprises a calibration rod 21 and a calibration ball 22 arranged on the calibration rod 21, the calibration rod 21 is arranged vertically on the calibration seat body 1, and the calibration ball 22 is arranged on the end of the calibration rod 21 away from the calibration seat body 1.

[0055] Here, it can be understood that the calibration rod 21 is used to support the calibration ball 22, and the calibration ball 22 is used for the four-wheel alignment measuring device to acquire images;

[0056] Specifically, the calibration rod 21 is arranged vertically in the calibration seat body 1, that is, the calibration rod 21 is arranged vertically on the calibration seat body 1; the calibration ball 22 is used for the four-wheel alignment measuring device to acquire images, the four-wheel alignment measuring device shoots the image of the calibration ball 22, and determines the coordinate value according to the center of the calibration ball 22, so as to calibrate the position of the four-wheel alignment measuring device; the calibration rod 21 is used to fix the calibration ball 22 at a predetermined height, so that the four-wheel alignment measuring device can acquire the calibration ball 22 at the predetermined height, which is beneficial to the four-wheel alignment measuring device to determine the coordinate value.

[0057] Optionally, the shape of the calibration ball 22 is a sphere, and the camera of the four-wheel alignment measuring device can calculate the center of the calibration ball 22 from the side or the front of the calibration ball 22. When calibrating the four-wheel alignment measuring device, the image of the calibration ball 22 is acquired from different calibration directions, that is, the image of the calibration ball 22 acquired from each different angle is a circular pattern.

[0058] The working principle of the calibration component 2 of the embodiment is as follows:

[0059] The calibration component 2 is fixed near the vehicle, for example, between two tire alignment measuring devices corresponding to the four wheels; the calibration rod 21 has a preset height, the calibration rod 21 supports the calibration ball 22 so that the calibration ball 22 is at the preset height, the tire alignment measuring device is used to obtain an image of the calibration ball 22, the image of the calibration ball 22 is a circle, the tire alignment measuring device analyzes the center of the image of the calibration ball 22, and analyzes the coordinate value, and then calibrates the position of the tire alignment measuring device itself.

[0060] It needs to be further explained that the tire alignment measuring device can shoot the image of the calibration ball 22 from multiple calibration directions, because no matter from which calibration direction the image of the calibration ball 22 is shot, the image of the calibration ball 22 is a circle, and the center position is unchanged, so the calibration ball 22 of the embodiment can be applied to calibrate the tire alignment measuring device in multiple directions.

[0061] By adopting the above technical scheme, the calibration of the tire alignment measuring device in multiple directions can be completed by setting only one calibration component 2, the consistency of the calibration result is improved, and the error of the calibration result is reduced.

[0062] In one embodiment, the calibration component 2 further comprises a connecting part 23, the connecting part 23 connects the calibration ball 22 and the calibration rod 21, and the diameter of the connecting part 23 is smaller than the diameter of the calibration rod 21.

[0065] By adopting the above technical scheme, the connecting part 23 connects the calibration ball 22 and the calibration rod 21, and the accuracy of the calibration operation of the calibration ball 22 and the supporting effect of the calibration rod 21 are considered.

[0066] In one embodiment, the calibration component 2 further comprises a first transition part 24, which connects the calibration ball 22 and the connecting part 23 in a smooth transition; and a second transition part 25, which connects the calibration rod 21 and the connecting part 23 in a smooth transition.

[0067] Here, it can be understood that the first transition part 24 is used to connect the calibration ball 22 and the connecting part 23, one end of the first transition part 24 is connected with the calibration ball 22, and the other end of the first transition part 24 is connected with the connecting part 23; and the second transition part 25 is used to connect the calibration rod 21 and the connecting part 23, one end of the second transition part 25 is connected with the calibration rod 21, and the other end of the second transition part 25 is connected with the connecting part 23.

[0068] Specifically, the first transition part 24 connects the calibration ball 22 and the connecting part 23 in a smooth transition, avoiding the generation of sharp corners between the calibration ball 22 and the connecting part 23 to affect the image of the calibration ball 22; and the second transition part 25 connects the calibration rod 21 and the connecting part 23 in a smooth transition, avoiding the generation of sharp corners between the calibration rod 21 and the connecting part 23 to affect the image of the calibration ball 22.

[0069] It needs to be further explained that the first transition part 24 can also make the connection between the calibration ball 22 and the connecting part 23 more stable; and similarly, the second transition part 25 can also make the connection between the calibration rod 21 and the connecting part 23 more stable.

[0070] By adopting the above technical solution, the first transition part 24 and the second transition part 25 can reduce the possibility of forming sharp corners due to the connection of the calibration ball 22, the connecting part 23 and the calibration rod 21 in sequence, and reduce the influence on the image of the calibration ball 22; and the first transition part 24 and the second transition part 25 can also stabilize the stability of the connection of the calibration ball 22, the connecting part 23 and the calibration rod 21 in sequence.

[0071] In one embodiment, the length of each calibration rod 21 is different.

[0072] Here, it can be understood that the calibration rod 21 is used to support the calibration ball 22, and the calibration ball 22 is used to provide an image for the four-wheel alignment measuring device.

[0073] Specifically, the height of each calibration rod 21 is different, so that the height of the calibration ball 22 arranged on the calibration rod 21 relative to the calibration seat body 1 is different.

[0075] In one embodiment, the height of the plurality of calibration rods 21 increases by 6mm in sequence.

[0076] Here, it can be understood that the heights of the plurality of calibration rods 21 are not the same, and the heights of the plurality of calibration rods 21 are sequentially increased by 6 mm, so that the plurality of calibration balls 22 are uniformly distributed at different heights in the calibration seat body 1.

[0077] By adopting the above technical scheme, it can be basically ensured that the distribution of the calibration balls 22 on the calibration seat body 1 is as dispersed as possible, and mutual shielding of the calibration balls 22 is avoided.
