In the description of this application, "plurality" means two or more, unless otherwise specifically defined. The following is a more detailed description of the specific implementation of this application in conjunction with specific embodiments:

[0048] As shown in Figures 1 and 2, an embodiment of the present application provides a calibration component. The four-wheel alignment measurement device in the four-wheel aligner is used to obtain an image of the calibration component to calibrate the position of the four-wheel alignment measurement device. That is, the four-wheel alignment measurement device calibrates its own position by obtaining the image of the calibration component. The calibration component of this embodiment can make the calibration result of the four-wheel alignment measurement device highly accurate, and thus make the tire positioning information detected by the four-wheel aligner highly accurate. The following is an explanation through specific embodiments:

[0049] The calibration components of this embodiment include:

[0050] A calibration base 1 and multiple calibration components 2, the calibration base 1 defines at least two calibration directions parallel to the calibration base 1, the multiple calibration components 2 are arranged in the calibration base 1, the projections of the multiple calibration components 2 along the calibration directions do not overlap with each other, and the multiple calibration components 2 are at different heights on the calibration base 1.

[0051] Here, it can be understood that the calibration base 1 is used to support the calibration component 2; the calibration component 2 is used for the four-wheel alignment measurement device to obtain a calibration image, and the four-wheel alignment measurement device analyzes the calibration image to obtain coordinate information, and then calibrates its own position;

[0052] Specifically, a plurality of calibration components 2 are provided on the calibration base 1, and a preset distance is spaced between the calibration base 1 and the four-wheel alignment measurement device, so that it is convenient for the four-wheel alignment measurement device to obtain images of the plurality of calibration components 2 on the calibration base 1, and it is also convenient for the four-wheel alignment measurement device to calculate the coordinate value according to the distance between the calibration base 1 and the calibration base 1; the calibration base 1 defines at least two calibration directions, and the calibration direction is parallel to the calibration base 1, which specifically refers to the calibration direction being parallel to the surface of the calibration base 1 used to support the calibration components 2; the four-wheel alignment measurement device and the calibration component are both located in the calibration direction, that is, the four-wheel alignment measurement device can obtain an image of the calibration component in the calibration direction, and the image For calibration image, that is, the four-wheel alignment measurement device can obtain the image of the calibration component 2 along the calibration direction; the calibration base 1 defines at least two calibration directions, that is, at least two four-wheel alignment measurement devices can simultaneously obtain the image of the calibration component 2, and at the same time, the projections of multiple calibration components 2 along the calibration direction do not overlap with each other, and the heights of multiple calibration components 2 are different. In this way, the four-wheel alignment measurement device can simultaneously obtain the images of multiple calibration components 2 with different heights. The images of multiple 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 measurement device.

[0053] It needs to be further explained that the number of calibration components 2 is positively correlated with the accuracy of the four-wheel alignment measurement device in determining its own position, that is, the more calibration components 2 there are, the more images of the calibration components 2 the four-wheel alignment measurement device obtains, and the more accurate the position it can analyze; specifically, the height of each calibration component 2 is different, and the position of each calibration ball is different, so that the four-wheel alignment measurement device can obtain the position coordinates of different calibration components 2, so that the four-wheel alignment measurement device can obtain different data of multiple calibration components 2 at the same time, thereby increasing the accuracy of position analysis.

[0054] By adopting the above technical solution, multiple four-wheel alignment measurement devices of the four-wheel alignment instrument can obtain calibration images of the calibration component 2 from different calibration directions, so that multiple four-wheel alignment measurement devices can perform calibration operations by sharing one calibration component, reducing the demand for calibration components and improving calibration efficiency. At the same time, the calibration base 1 is formed with at least two calibration directions, which can also improve the accuracy of the calibration result; at the same time, the calibration base 1 is provided with multiple calibration components 2 whose projections in the calibration direction do not overlap with each other, so that the four-wheel alignment measurement device can obtain images of multiple calibration components 2 in the calibration direction. The images of the multiple calibration components 2 can provide more coordinate values ​​and calibrate with 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 measurement device.

[0055] Please refer to Figure 3 as well. In one embodiment, the calibration component 2 includes a calibration rod 21 and a calibration ball 22 provided on the calibration rod 21. The calibration rod 21 is upright on the calibration base 1, and the calibration ball 22 is provided on the end of the calibration rod 21 away from the calibration base 1.

[0056] 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 measurement device to obtain an image;

[0057] Specifically, the calibration rod 21 is erected in the calibration base body 1, that is, the calibration rod 21 is vertically arranged on the calibration base body 1; the calibration ball 22 is used for the four-wheel alignment measurement device to obtain an image, and the four-wheel alignment measurement device takes an image of the calibration ball 22 and determines the coordinate value according to the center of the calibration ball 22, thereby calibrating the position of the four-wheel alignment measurement device; the calibration rod 21 is used to fix the calibration ball 22 at a preset height, so that the four-wheel alignment measurement device can obtain the calibration ball 22 at the preset height, which is beneficial for the four-wheel alignment measurement device to determine the coordinate value.

[0058] Optionally, the calibration ball 22 is shaped like 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 front of the calibration ball 22. When calibrating the four-wheel alignment measuring device, images of the calibration ball 22 must be obtained from different calibration directions, that is, the images of the calibration ball 22 obtained from different angles are all circular patterns.

[0059] The working principle of the calibration component 2 of this embodiment is as follows:

[0060] The calibration component 2 is fixed near the vehicle. For example, it can be set between two four-wheel alignment measurement devices corresponding to the tires one by one; the calibration rod 21 has a preset height, and the calibration rod 21 supports the calibration ball 22 so that the calibration ball 22 is located at the preset height. The four-wheel alignment measurement device is used to obtain the image of the calibration ball 22. The image of the calibration ball 22 is circular. The four-wheel alignment measurement device analyzes the center of the image of the calibration ball 22, and uses this to analyze the coordinate value, and then calibrates the position of the four-wheel alignment measurement device itself.

[0061] It needs to be further explained that the four-wheel alignment measurement device can capture images of the calibration ball 22 from multiple calibration directions. Because no matter from which calibration direction the image of the calibration ball 22 is captured, the image of the calibration ball 22 is circular and the position of the center of the circle remains unchanged. Therefore, the calibration ball 22 of this embodiment can be used to calibrate the four-wheel alignment measurement device in multiple directions.

[0062] By adopting the above technical solution, only one calibration component 2 is required to complete the calibration of the four-wheel alignment measurement device in multiple directions, thereby improving the consistency of the calibration results and reducing the errors of the calibration results.

[0063] In one embodiment, the calibration component 2 further includes a connecting portion 23 , which connects the calibration ball 22 and the calibration rod 21 . The diameter of the connecting portion 23 is smaller than the diameter of the calibration rod 21 .

[0064] Here, it can be understood that the connecting portion 23 is used to connect the calibration ball 22 and the calibration rod 21;

[0065] Specifically, the connecting portion 23 is located between the calibration ball 22 and the calibration rod 21, one end of the connecting portion 23 is connected to the calibration ball 22, and the other end of the connecting portion 23 is connected to the calibration rod 21. The diameter of the connecting portion 23 is smaller than the diameter of the calibration rod 21, that is, the diameter of the connecting portion 23 is the smallest among the connecting portion 23, the calibration ball 22 and the calibration rod 21, which ensures the connection between the calibration ball 22 and the calibration rod 21, and also reduces the influence of the thicker calibration rod 21 on the image of the calibration ball 22 taken by the four-wheel alignment measurement device; in addition, the diameter of the calibration rod 21 is larger than the diameter of the connecting portion 23, which ensures that the calibration rod 21 has a larger diameter, so that the calibration rod 21 has a stronger mechanical strength, so that the calibration rod 21 can provide sufficient support force for the calibration ball 22.

[0066] By adopting the above technical solution, the connecting portion 23 connects the calibration ball 22 and the calibration rod 21 , taking into account both the accuracy of the calibration operation of the calibration ball 22 and the supporting function of the calibration rod 21 .

[0067] In one embodiment, the calibration component 2 further includes a first transition portion 24 , which smoothly transitions and connects the calibration ball 22 and the connecting portion 23 ; the calibration component 2 further includes a second transition portion 25 , which smoothly transitions and connects the calibration rod 21 and the connecting portion 23 .

[0068] Here, it can be understood that the first transition portion 24 is used to connect the calibration ball 22 and the connecting portion 23, one end of the first transition portion 24 is connected to the calibration ball 22, and the other end of the first transition portion 24 is connected to the connecting portion 23; the second transition portion 25 is used to connect the calibration rod 21 and the connecting portion 23, one end of the second transition portion 25 is connected to the calibration rod 21, and the other end of the second transition portion 25 is connected to the connecting portion 23;

[0069] Specifically, the first transition portion 24 smoothly connects the calibration sphere 22 and the connecting portion 23 to avoid sharp corners between the calibration sphere 22 and the connecting portion 23 that affect the image of the calibration sphere 22; the second transition portion 25 smoothly connects the calibration rod 21 and the connecting portion 23 to avoid sharp corners between the calibration rod 21 and the connecting portion 23 that affect the image of the calibration sphere 22.

[0070] It needs to be further explained that the first transition portion 24 can also make the connection between the calibration ball 22 and the connecting portion 23 more stable; similarly, the second transition portion 25 can also make the connection between the calibration rod 21 and the connecting portion 23 more stable.

[0071] By adopting the above-mentioned technical solution, the first transition portion 24 and the second transition portion 25 can reduce the possibility of sharp corners formed by connecting the calibration ball 22, the connecting portion 23 and the calibration rod 21 of different diameters in sequence, thereby reducing the influence of the image of the calibration ball 22; at the same time, the first transition portion 24 and the second transition portion 25 can ensure the stability of the calibration ball 22, the connecting portion 23 and the calibration rod 21 connected in sequence.

[0072] In one embodiment, each calibration rod 21 has a different length.

[0073] 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 measurement device to obtain an image;

[0074] Specifically, the height of each calibration rod 21 is different, so that the height of the calibration ball 22 provided on the calibration rod 21 relative to the calibration base 1 is different.

[0075] By adopting the above technical solution, it is achieved that each calibration component 2 has a different height.

[0076] In one embodiment, the heights of the plurality of calibration rods 21 increase in sequence by 6 mm.

[0077] Here, it can be understood that the heights of the multiple calibration rods 21 are different, and the heights of the multiple calibration rods 21 increase in sequence by 6 mm, so that the multiple calibration balls 22 are evenly distributed in the calibration seat 1 at different heights.

[0078] By adopting the above technical solution, it can be basically ensured that the calibration balls 22 are distributed as dispersedly as possible on the calibration base 1, avoiding mutual obstruction of the calibration balls 22.

[0079] In one embodiment, the calibration assembly also includes a calibration cover 3, which is arranged above the calibration base 1. A calibration space is formed between the calibration cover 3 and the calibration base 1. The calibration space is formed with at least two calibration openings 4. The opening direction of the calibration opening 4 is the same as the calibration direction. The calibration base 1 is located in the calibration space, and the calibration opening 4 is used to expose the calibration component 2.

[0080] Here, it can be understood that the calibration cover 3 is used to protect the calibration component 2;

[0081] Specifically, the calibration cover 3 is arranged above the calibration base 1, and a calibration space is formed between the two. The calibration space is formed with a calibration opening 4, and the opening direction of the calibration opening 4 is consistent with the calibration direction. The calibration space is provided with a calibration base 1, and the calibration opening 4 is used to expose the calibration component 2 in the calibration space.

[0082] By adopting the above technical solution, a calibration space for accommodating the calibration component 2 is formed between the calibration cover 3 and the calibration base 1, thereby improving the protection performance of the calibration component 2. At the same time, a calibration opening 4 for exposing the calibration component 2 is formed in the calibration space.

[0083] In one embodiment, the calibration assembly further includes a calibration side cover 5 , which is used to connect the calibration cover body 3 and the calibration base body 1 , so that three calibration openings 4 are formed in the calibration space.

[0084] Here, it can be understood that the calibration side cover 5, the calibration cover body 3 and the calibration base body 1 enclose a calibration space and form a calibration opening 4 connected to the calibration space, and the calibration opening 4 corresponds to three different calibration directions respectively.

[0085] By adopting the above technical solution, the calibration space is formed with calibration openings 4 corresponding to three different calibration directions.

[0086] In one embodiment, the calibration assembly is further provided with a light-transmitting cover 6 , which is connected to the calibration cover 3 , the calibration seat 1 and the calibration side cover 5 . The light-transmitting cover 6 is used to cover the calibration opening 4 .

[0087] Here, it can be understood that the four-wheel alignment measurement device can obtain the calibration image of the calibration component 2 through the transparent cover 6;

[0088] Specifically, the transparent cover 6 is connected to the calibration cover 3, the calibration seat 1 and the calibration side cover 5. The transparent cover 6 is used to cover the calibration opening 4, so that the transparent cover 6 protects the calibration component 2 in the calibration space.

[0089] By adopting the above technical solution, the transparent cover 6 further improves the protection performance of the calibration component 2.

[0090] Please refer to FIG. 4 . In one embodiment, the calibration assembly is further provided with an illumination member 7 . The illumination member 7 is provided on the calibration cover 3 . The illumination member 7 is used to illuminate the calibration component 2 in the calibration base 1 .

[0091] Here, it can be understood that the lighting element 7 is used to increase the brightness in the calibration space so that the calibration component 2 is illuminated, making it easier for the four-wheel alignment measurement device to obtain a stable calibration image, thereby improving the accuracy of the recognition and analysis results.

[0092] By adopting the above technical solution, the four-wheel alignment measurement device can more easily obtain a stable calibration image, thereby improving the accuracy of the recognition and analysis results.

[0093] In one embodiment, the lighting element 7 is a lighting flat plate, which is laid flat on the surface of the calibration cover close to the calibration component 2 , and the lighting range of the lighting element 7 covers multiple calibration components 2 .

[0095] In one embodiment, the calibration component is further provided with a reflector 8 , which is provided on the calibration base 1 , and is used to reflect the light emitted by the lighting element 7 .

[0096] Here, it can be understood that the reflective element 8 is used to further increase the brightness of the calibration space.

[0097] By adopting the above technical solution, the four-wheel alignment measurement device can more easily obtain a stable calibration image, thereby improving the accuracy of the recognition and analysis results.
