[0047] A first telescopic assembly 7, whose telescopic direction is parallel to the central axis of the lens 5, and whose telescopic end is connected to a first adjusting ball head rod 8 connected to the second ball joint connector 3;

[0048] The second telescopic assembly 9 has a telescopic direction parallel to the central axis of the lens 5 , and a second adjusting ball head rod 10 connected to the third ball joint connector 4 is connected to the telescopic end thereof.

[0049] The above-mentioned automotive lamps cancel the screw adjustment method, and no holes are required on the lamp housing for screw connection, so there is no risk of sealing failure, and the lamps are less likely to get water ingress and fogging.

[0050] In addition, the automobile lamp also includes a signal receiver, a lamp controller and a drive controller; the drive controller is connected to the first telescopic component 7 and the second telescopic component 9; the signal receiver is connected to the lamp controller; the lamp controller is connected to the drive controller; the lamp controller of the front combination lamp automatic calibration system is used to derive the adjustment direction and angle according to the detection information received by the signal receiver, so as to control the first telescopic component 7 and the second telescopic component 9 to achieve the purpose of adjusting the posture of the lens bracket 1; thereby, automatic calibration and adjustment can be achieved according to the detected structure, speeding up the calibration steps of the high and low beam functions of the automobile lamp, and speeding up the vehicle offline process; and it is also convenient for adjustment during subsequent use without disassembling the vehicle.

[0051] In some preferred embodiments, the first ball joint connector 2, the second ball joint connector 3 and the third ball joint connector 4 all include a fixing tube; a bracket connecting portion 11 is provided on the outer side of the fixing tube, and a spherical connecting groove is provided on the end surface of one end of the fixing tube;

[0052] The lens bracket 1 is provided with three mounting grooves corresponding to the first ball joint connector 2 , the second ball joint connector 3 and the third ball joint connector 4 .

[0053] The fixed ball head rod 6, the first adjusting ball head rod 8 and the second adjusting ball head rod 10 are all provided with a connecting rod, one end of the connecting rod is provided with a ball head 12 connected to the spherical connecting groove;

[0055] The above introduces the specific structure for achieving adjustment, and the components through which the lamp can be connected to the vehicle body. For example, the second telescopic component 9 and the first telescopic component 7 can be connected to the vehicle body through the motor bracket 14; the fixed ball head rod 6 is connected to the vehicle body through the vehicle body connecting plate 13 to achieve the fixed installation of the entire vehicle lamp; the light detector 15 is adjusted, no manual adjustment is required, and it is convenient for subsequent adjustment.

To illustrate the adjustment principle of the above structure, refer to the attached Figure 3 and 4 The adjustment principle is explained below.

[0056] According to experience and theoretical calculations, lighting calibration generally requires an adjustment angle of 2° in each direction to meet the lighting adjustment requirements. The extension and retraction of the linear telescopic motor is based on the following Figure 1 Taking the automobile lamp as an example, the horizontal adjustment stroke is ±7.6mm, and the vertical adjustment stroke is ±5mm.

[0057] Second, reference Figure 5 , provides a front combination lamp automatic calibration system, which includes:

[0058] A light detector 15, which is used to obtain detection information; the detection information includes the optical axis offset of the front combination lamp to be calibrated;

[0059] A detection information transmitter is used to send detection information to the automobile lamp; the automobile lamp also includes a signal receiver, a lamp controller and a drive controller; the drive controller is connected to the first telescopic component 7 and the second telescopic component 9; the signal receiver is connected to the lamp controller; the lamp controller is connected to the drive controller; the lamp controller is used to control the first telescopic component 7 and the second telescopic component 9 according to the detection information received by the signal receiver to adjust the posture of the lens bracket 1.

[0060] The detection information transmitter is a star flash transmitter, the signal receiver is a star flash receiver, the lamp controller is an HCM controller, and the drive controller is an LDM controller.

[0061] The automatic calibration system for the front combination lamp can automatically obtain detection information, and then the lamp controller of the automatic calibration system for the front combination lamp is used to obtain the adjustment direction and angle according to the detection information received by the signal receiver, so as to control the first telescopic component 7 and the second telescopic component 9, so as to achieve the purpose of adjusting the posture of the lens bracket 1; thereby, automatic calibration and adjustment can be achieved according to the detected structure, speeding up the calibration steps of the high and low beam functions of the automobile lamps, and speeding up the vehicle offline process; and it is also convenient for adjustment in the subsequent use process without disassembling the vehicle.

[0062] In a third aspect, a method for automatic calibration of front combination lamps is provided, which comprises the following steps:

[0063] Step 100: providing a front combination lamp automatic calibration system; the front combination lamp includes a plurality of automobile lamps;

[0064] Step 200: input the qualified range information of the light corresponding to the automobile lamp into the light detector 15, and then use the light detector 15 to detect the light beam emitted by the automobile lamp to obtain the optical axis offset, and then calculate the adjustment angle and adjustment direction according to the optical axis offset; this step specifically includes:

[0065] Using the qualified light range information, a light boundary range box of the light detector 15 is obtained;

[0066] Determine whether the characteristic points of the low beam or high beam of the vehicle lamp model fall within the light boundary range box;

[0067] If so, no adjustment is required;

[0068] If not, then obtain the optical axis offset of the feature point relative to the light boundary range box, and obtain the adjustment angle and adjustment direction according to the offset direction and offset value of the optical axis offset. For example, if the offset value d between the feature point and the light boundary range box in the up-down direction, the angle that needs to be rotated in the up-down direction is α=arctan(d / 10000), where d is in mm.

[0069] Step 300: Use the lamp controller to control the corresponding first telescopic assembly 7 or second telescopic assembly 9 to adjust the lens bracket 1 according to the adjustment angle and adjustment direction. Step 300 specifically includes the following steps:

[0070] When the adjustment direction is left and right, the lamp controller controls the first telescopic assembly 7 to extend and retract, so that the lens bracket 1 rotates the adjustment angle about the rotation axis formed by the center of the fixed ball head rod 6 and the center of the second adjustment ball head rod 10; Figure 3 , at this time the rotation axis is marked B

[0071] When the adjustment direction is up and down, the lamp controller controls the second telescopic assembly 9 to extend and retract, so that the lens bracket 1 rotates the rotation axis formed by the center of the fixed ball head rod 6 and the center of the first adjustment ball head rod 8 to adjust the angle. Figure 4 , at this time the rotation axis is marked A.

[0072] The above automatic calibration method for front combination lamps also has the following steps: First, the light detector 15 detects the luminous intensity and beam irradiation position (i.e., optical axis offset) of the motor vehicle headlamp. Drive the vehicle under inspection into the headlamp detector in the vertical direction along the track of the headlamp detector, so that the headlamp is 10m away from the detector receiver. Use the vehicle aligner to align the detector with the inspected vehicle. Turn on the headlamp and turn on the power of the detector. The light detector automatically moves to the position corresponding to the light according to the built-in calibration program, so that the headlamp beam irradiates the receiver. Press the measurement switch on the controller, and the optical receiver will track the luminous intensity and optical axis of the headlamp. The built-in calibration program defines the qualified range of lights according to the height and width of lights of different models. For example, the qualified height of low beam is 0.6~0.8H, the width should be within 170mm to the left and within 350mm to the right, where H is the height of the center of the light from the ground. As long as it is within the upper and lower limits formed by the height and width, the light meets the design requirements. The qualified range information of the lights of a certain model is input into the light detector. When the lights of this model are offline calibrated, a box (the above light boundary range box) will be formed on the screen of the light detector. Move the characteristic points of low beam and high beam into the box, and the light will be adjusted to be qualified. The characteristic point of low beam is the inflection point of the end line, and the characteristic point of high beam is the center point of the light, that is, the maximum light intensity point. The light detector 15 determines whether the lamp needs to be adjusted and the adjustment angle through the relationship between the characteristic point of the light and the box; when the characteristic point falls within the box area, the light is OK and does not need to be adjusted.

[0073] The vehicle has multiple lamps (right front combination lamp, left front combination lamp), and the distribution positions on the front of the vehicle are different. The following steps should be taken:

[0074] First, block the right front combination lamp to prevent light from leaking out, adjust the second telescopic component 9, so that the height of the cut-off angle or midpoint of the low beam in the far / low beam of the left lamp is 0.6H~0.8H; adjust the first telescopic component 7, so that the low beam in the far / low beam should deviate within 170mm to the left horizontally and within 350mm to the right. After adjusting the low beam on the left, block the left front combination lamp to prevent light from leaking out, adjust the low beam in the far / low beam on the right, so that the cut-off angle or midpoint of the low beam of the right lamp is 0.6H~0.8H, and the low beam should deviate within 170mm to the left horizontally and within 350mm to the right. Adjustment of the high beam irradiation position: The high beam is irradiated on the screen. The requirements are: first, block the right front combination lamp to prevent light from leaking out, adjust the second telescopic component 9, so that the height of the high beam in the high / low beam of the left lamp is 0.8H~0.95H; adjust the first telescopic component 7, so that the high beam horizontally deviates to the left within 170mm, and to the right within 350mm. The adjustment method of the single high beam of the left lamp is the same as that of the high / low beam. After adjusting the high beam on the left, block the left front combination lamp to prevent light from leaking out, adjust the high beam in the high / low beam on the right, so that the height of the high beam in the high / low beam of the right lamp is 0.8H~0.95H, and the high beam horizontally deviates to the left within 350mm, and to the right within 350mm. The adjustment method of the single high beam of the right lamp is the same as above.
