Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of detection and instrument calibration, in particular to an intelligent calibrator and calibration method for headlamp detector calibration. BACKGROUND

[0002] Currently, with the rapid development and growth of the global new energy vehicle field, traffic safety has become a global focus. In order to ensure night driving safety and effectively avoid traffic accidents caused by insufficient vision, countries have implemented a series of strict technical requirements and laws and regulations for the light beams of motor vehicle headlamps. The headlamp not only plays a key role in illuminating the road ahead for the driver, but also the brightness, color temperature and directivity of its light beam are directly related to the visual comfort and driving safety of the driver.

[0003] Therefore, motor vehicle headlamp detection has become an indispensable part of motor vehicle annual inspection, quality supervision and vehicle maintenance. The motor vehicle headlamp detector, as the core equipment in this detection process, is crucial for its accuracy and reliability. It can quickly and accurately evaluate the performance of the vehicle headlamp to ensure that the vehicle can provide sufficient, uniform and appropriate lighting in the night or low visibility conditions, thereby reducing driver eye fatigue and enhancing night driving safety.

[0004] The prior art Chinese patent document CN118424100A discloses a contour automatic recognition and center alignment device and method for headlamp detector calibration, which mainly includes a lamp stand, a lamp holder, a standard light source, a linear motion mechanism, an angle adjusting mechanism, a pitch motor, a pitch adjusting shaft, a laser displacement sensor and a visual recognition sensor. The device mainly uses the visual recognition sensor to identify the size of the light receiving surface of the headlamp detector, calculates the center coordinates through the control unit, and then moves the standard light source to the center coordinates to realize the coincidence of the standard light source and the optical axis center of the headlamp detector. However, the following problems may occur during actual calibration: 1. The performance of the visual recognition sensor is affected, such as weak reflection of glass, and the visual recognition sensor cannot 100% identify the size of the light receiving surface of the headlamp detector; 2. After the frame of the headlamp detector is deformed, the center coordinates calculated by the visual recognition sensor are inaccurate; 3. The structure is complex and difficult to maintain.

[0087] Embodiment 2

[0088] A calibration method suitable for the intelligent calibrator for headlamp detector calibration shown in embodiment 1, comprising the following steps:

[0089] Firstly, the optical axis center of the headlamp 150 is coincided with the center of the first lamp holder mechanism 1;

[0090] The optical axis center of the headlamp 150 is coincided with the center point P of the first lamp holder mechanism 1 through the headlamp moving mechanism 160.

[0091] Secondly, the device is preheated and the device is set to return to the initial position;

[0092] Start the device, the intelligent control system 5 sets the four displacement sensor mechanisms (the first displacement sensor mechanism 110, the second displacement sensor mechanism 120, the third displacement sensor mechanism 130, and the fourth displacement sensor mechanism 140) to the initial state, that is, the optical axis centers of the four displacement sensors (the first displacement sensor 113, the second displacement sensor 123, the third displacement sensor 133, and the fourth displacement sensor 143) are respectively parallel to the optical axis center of the headlamp 150, and the distances from the optical axis center of the headlamp 150 are equal.

[0093] The third step is that the center line of the plane where the headlamp 150 is located is parallel to the plane where the headlamp detector 170 is located.

[0094] The intelligent control system 5 sets the second displacement sensor 123 and the fourth displacement sensor 143 located on the left and right sides of the headlamp 150 to 1 meter, and the intelligent control system 5 controls the first electric wheel 421, the second electric wheel 422, the third electric wheel 423, and the fourth electric wheel 424 to move forward and backward and left and right until the second displacement sensor 123 and the fourth displacement sensor 143 are both 1 meter away from the plane where the headlamp detector 170 is located. At this time, the horizontal center line of the plane where the headlamp 150 is located is parallel to the plane where the headlamp detector 170 is located.

[0095] The fourth step is that the bottom surface of the calibrator is parallel to the ground.

[0096] The intelligent control system 5 controls the first hydraulic lifting foot 411, the second hydraulic lifting foot 412, the third hydraulic lifting foot 413, and the fourth hydraulic lifting foot 414 to move upward to support the device, and controls the first hydraulic lifting foot 411, the second hydraulic lifting foot 412, the third hydraulic lifting foot 413, and the fourth hydraulic lifting foot 414 to move up and down according to the feedback information of the gyroscope 430 until the bottom surface of the device is parallel to the ground. The intelligent control system 5 records the up and down movement data of the four hydraulic lifting feet respectively, and names them as the initial position of the lifting feet.

[0097] The fifth step is that the plane where the headlamp 150 is located is parallel to the plane where the headlamp detector 170 is located.

[0098] The intelligent control system 5 checks whether the first displacement sensor 113 and the third displacement sensor 133 are set to 1 meter. If both are 1 meter, the plane where the headlight 150 is located is parallel to the plane where the headlight detector 170 is located. If not, it means that the headlight detector 170 is not parallel to the bottom surface. The intelligent control system 5 controls the first hydraulic lifting foot 411, the second hydraulic lifting foot 412, the third hydraulic lifting foot 413, and the fourth hydraulic lifting foot 414 to move up and down until the distance between the first displacement sensor 113 and the third displacement sensor 133 and the plane where the headlight detector 170 is located is 1 meter. The system records the data of the four lifting feet (first hydraulic lifting foot 411, second hydraulic lifting foot 412, third hydraulic lifting foot 413, and fourth hydraulic lifting foot 414) at this time and names it the initial parallel position. At this time, the plane where the headlight 150 is located is parallel to the plane where the headlight detector 170 is located.

[0099] Step 6: The displacement sensor rotates and scans to align the optical axis center of the headlight 150 with the optical axis center of the headlight detector 170 in the vertical direction.

[0100] The intelligent control system 5 first controls the second displacement sensor 123 and the fourth displacement sensor 143 to rotate to a certain angle. Then, the intelligent control system 5 controls the lamp holder moving mechanism 3 to move repeatedly in the left and right directions. The intelligent control system 5 records and calculates whether the distances fed back by the second displacement sensor 123 and the fourth displacement sensor 143 are equal. If they are not equal, the intelligent control system 5 controls the second displacement sensor 123 and the fourth displacement sensor 143 to rotate inward by 1 degree. Then, the intelligent control system 5 controls the lamp holder moving mechanism 3 to move repeatedly in the left and right directions. The intelligent control system 5 records and calculates whether the distances fed back by the second displacement sensor 123 and the fourth displacement sensor 143 are equal. If they are not equal, the second displacement sensor 123 and the fourth displacement sensor 143 continue to rotate inward until the distances fed back by the second displacement sensor 123 and the fourth displacement sensor 143 are equal.

[0101] like Figure 7 As shown, the angle between the second displacement sensor 123 and the optical axis center of the headlight 150 is θ, and the distance between the second displacement sensor 123 and the left side A of the headlight detector frame 171 is L2; ​​the angle between the fourth displacement sensor 143 and the optical axis center of the headlight 150 is α, and the distance between the fourth displacement sensor 143 and the right side B of the headlight detector frame 171 is L1. When θ=α and L1=L2, in the vertical direction, the optical axis center point P of the headlight 150 is aligned with the optical axis center O of the headlight detector 170, and the center coordinate x of the first lamp holder mechanism 1 in the horizontal direction is recorded.

[0102] Since the second displacement sensor 123 and the fourth displacement sensor 143 are located on the horizontal center line S of the plane where the first lamp holder mechanism 1 is located, and are equidistant from the center point P of the first lamp holder mechanism 1, and rotate at the same frequency and angle on the horizontal center line S, and since the optical axis center of the headlamp 150 coincides with the center point P of the first lamp holder mechanism 1, that is, when the second displacement sensor 123 and the fourth displacement sensor 143 rotate and scan, the optical axis center of the headlamp 150 is always located at the center of the two sensors, under the premise that the plane where the headlamp 150 is located is parallel to the plane where the headlamp detector 170 is located, when the angle of the second displacement sensor 123 and the fourth displacement sensor 143 and the distance from the two sides of the plane where the headlamp detector 170 is located are equal, the optical axis center point P of the headlamp 150 coincides with the optical axis center O of the headlamp detector 170 in the vertical direction.

[0103] The intelligent control system 5 controls the lamp holder moving mechanism 3 to move upward by a certain distance, repeats the above steps, and finds the center coordinate x1 of the first lamp holder mechanism 1 in the horizontal direction again. When x=x1, it is determined that the center coordinate of the first lamp holder mechanism 1 in the horizontal direction is x. When x≠x1, repeat all the above steps until x=x2 or x2=x1, and determine that the center coordinate in the horizontal direction is x or x1.

[0104] The center coordinate x of the first lamp holder mechanism 1 in the horizontal direction is determined by multiple times of finding, in order to avoid errors caused by deformation of the sides of the headlamp detector 170.

[0105] In the seventh step, the displacement sensor rotates and scans, so that the optical axis center of the headlamp 150 is aligned with the optical axis center of the headlamp detector 170 in the horizontal direction.

[0106] Similarly, the intelligent control system 5 controls the lamp holder moving mechanism 3 to repeatedly move in the up-down direction, and the first displacement sensor 113 and the third displacement sensor 133 rotate and scan at the same angle from a certain angle to the minimum angle. When the rotation angles of the first displacement sensor 113 and the third displacement sensor 133 are the same, and the distances from the upper and lower frames of the headlamp detector 170 are equal, at this time, in the horizontal direction, the optical axis center point P of the headlamp 150 is aligned with the optical axis center O of the headlamp detector 170, and the center coordinate y of the first lamp holder mechanism 1 in the vertical direction is recorded. Multiple times of finding the center coordinate y in the vertical direction are also adopted to avoid errors caused by deformation of the sides of the headlamp detector 170.

[0107] At this time, in the vertical direction, the optical axis center point P of the headlamp 150 is aligned with the optical axis center O of the headlamp detector 170, and in the horizontal direction, the optical axis center point P of the headlamp 150 is aligned with the optical axis center O of the headlamp detector 170, that is, the optical axis center of the calibrator coincides with the optical axis center of the headlamp detector 170.

[0108] Eighth step, calibrate the front lamp detector 170 surface;

[0109] The operator adjusts the brightness and color temperature parameters of the headlamp 150 through the intelligent control system 5, and carries out the calibration of the high beam intensity and low beam intensity parameters; the intelligent control system 5 makes the headlamp 150 complete the deflection movement of 2° rotation left and right through the lamp holder rotating mechanism 2, and carries out the calibration of the light beam intensity at different angles left and right of the front lamp detector 170; the intelligent control system 5 controls the first hydraulic lifting foot 411 and the fourth hydraulic lifting foot 414 to move up at the same time through the comprehensive adjustment mechanism 4, and the headlamp 150 completes the pitch movement of 2° rotation up and down, and the calibration of the light beam intensity at different angles up and down of the front lamp detector 170 is carried out. As shown in the figure, β is the included angle between the bottom surface of the calibrator and the horizontal plane. Figure 8

[0110] Example 3

[0111] Since the optical axis center of the front lamp detector 170 is not located at the center of the front lamp detector frame 171, part of the optical axis center of the front lamp detector 170 is located at the center of the front lamp detector glass outer screen 181 inside the front lamp detector frame 171. Therefore, the embodiment 3 provides a calibration method for the optical axis center of the front lamp detector 170 located at the front lamp detector glass outer screen 181, which comprises the following steps:

[0112] First step, the optical axis center of the headlamp 150 coincides with the center of the first lamp holder mechanism 1, which is the same as embodiment 2;

[0113] Second step, preheat the equipment, and set the equipment to return to the initial position, which is the same as embodiment 2;

[0114] Third step, the center line of the plane where the headlamp 150 is located is parallel to the plane where the front lamp detector 170 surface is located, which is the same as embodiment 2;

[0115] Fourth step, the bottom surface of the calibrator is parallel to the ground, which is the same as embodiment 2;

[0116] Fifth step, the plane where the headlamp 150 is located is parallel to the plane where the front lamp detector 170 surface is located, which is the same as embodiment 2;

[0117] Sixth step, the displacement sensor rotates and scans, so that the optical axis center of the headlamp 150 is vertically aligned with the optical axis center of the front lamp detector 170;

[0118] ​The intelligent control system 5 controls the lamp holder moving mechanism 3 to repeatedly move along the left-right direction, while the intelligent control system 5 controls the second displacement sensor 123 and the fourth displacement sensor 143 to scan inward along the horizontal center line S, that is, the lamp holder moving mechanism 3 moves left and right once, the second displacement sensor 123 and the fourth displacement sensor 143 reduce one degree, and the distances fed back by the two sensors are recorded. When the first angle and distance data are obtained, as shown in FIG. 6, θ = α, L1 = L2, at this time, the optical axis center point P of the headlamp 150 is aligned with the center O of the frame 171 of the headlamp detector, and the scanning continues until the second angle and distance data are obtained, as shown in FIG. 7, the angle between the second displacement sensor 123 and the optical axis center of the headlamp 150 is θ', and the distance between the second displacement sensor 123 and the left side A' of the frame 171 of the headlamp detector is L4; the angle between the fourth displacement sensor 143 and the optical axis center of the headlamp 150 is α', and the distance between the fourth displacement sensor 143 and the right side B' of the frame 171 of the headlamp detector is L3. θ' = α', L3 = L4, at this time, the optical axis center point P of the headlamp 150 is aligned with the center O' of the outer glass screen 181 of the headlamp detector, and the center coordinate x of the first lamp holder mechanism 1 in the horizontal direction is recorded. Figure 6 Figure 9

[0119] Step 7: The displacement sensor rotates and scans, so that the optical axis center of the headlamp 150 is aligned with the optical axis center of the headlamp detector 170 in the horizontal direction.

[0120] Similarly, the intelligent control system 5 controls the lamp holder moving mechanism 3 to repeatedly move along the up-down direction, and the first displacement sensor 113 and the third displacement sensor 133 scan from a certain angle to the minimum angle. When the first angle and distance data are obtained, the scanning continues until the second angle and distance data are obtained, the scanning stops, and the center coordinate y of the first lamp holder mechanism 1 in the vertical direction is recorded.

[0121] At this time, the optical axis center of the calibrator is coincided with the optical axis center of the headlamp detector 170.

[0122] Step 8: The face of the headlamp detector 170 is calibrated, which is the same as in Example 2.

[0123] Example 4

[0124] The difference between Example 4 and Example 1 is that the lamp holder mechanisms are different.

[0125] The overall structure of the intelligent calibrator for calibrating the headlamp detector in this embodiment includes a second lamp holder structure 21, a lamp holder rotating mechanism 2, a lamp holder moving mechanism 3, a comprehensive adjustment mechanism 4, and an intelligent control system 5.

[0126] As​​Figure 10 and 11 As shown, the second lamp holder mechanism 21 includes: a fifth displacement sensor mechanism 214, a circular sawtooth track 215, a second headlight 250, a headlight moving mechanism 160, a rotating mechanism 260, and a sawtooth rolling device 270. The structure of the headlight moving mechanism 160 is the same as in Embodiment 1, and will not be described again here.

[0127] The rotating mechanism 260 is connected to the circular sawtooth track 215 via sawtooths and is used to control the rotation of the circular sawtooth track 215; the headlight moving mechanism 160 is mechanically connected to the second headlight 250 and is used to adjust the optical axis center of the second headlight 250; the circular sawtooth track 215 is connected to the sawtooth rolling device 270 and is used to control the rotation and movement path of the fifth displacement sensor mechanism 214; the optical axis center of the second headlight 250 is located at the center of the circular sawtooth track 215; the fifth displacement sensor mechanism 214 is fixed inside the sawtooth rolling device 270.

[0128] like Figure 11 As shown, the fifth displacement sensor mechanism 214 includes a sixth hydraulic device 211 connected to a fifth rotating mechanism 212, and a fifth displacement sensor 213 located on the fifth rotating mechanism 212. The sixth hydraulic device 211 is a drive mechanism.

[0129] The rotating mechanism 260 uses a circular sawtooth track 215 to make the fifth displacement sensor 213 stop at points A, B, C, and D on the center line of the second lamp holder mechanism 21, and the fifth displacement sensor 213 can rotate along the center line.

[0130] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
