[0002] - A vertical adjustment device for adjusting the frame with respect to the horizontal axis, wherein the vertical adjustment device is configured to engage with the vertical adjustment bearing point of the frame.

[0003] - A horizontal adjustment device for adjusting the frame about the vertical axis, wherein the horizontal adjustment device is configured to engage with the horizontal adjustment bearing point of the frame.

[0004] The adjustable load-bearing points are arranged on the frame so that the imaginary connecting lines between the adjustable load-bearing points and the fixed load-bearing points form a triangle.

[0005] The imaginary connecting line between the vertical adjustment bearing point and the fixed bearing point forms a vertical axis, and the imaginary connecting line between the horizontal adjustment bearing point and the fixed bearing point forms a horizontal axis.

[0006] - A support for holding the vertical and horizontal adjustment devices and the frame, wherein the frame is mechanically connected to the support via fixed bearing points.

[0007] In addition, the present invention also relates to vehicle headlights, which include at least one adjustment system according to the present invention. Background Technology

[0008] In the prior art, the adjustment system for vehicle headlights, which is used to adjust the optical components of the vehicle headlights, typically includes sliding or gliding elements. The assembly of such elements is complex, and the tolerance chain between these elements must also be taken into account, which in turn requires higher precision in production, resulting in higher costs. Summary of the Invention

[0009] The objective of this invention is to provide an enhanced adjustment system for vehicle headlights.

[0010] To achieve this goal, the vertical adjustment device includes:

[0011] - A first lever element having a lever axis and a first end and a second end opposite to each other along the lever axis, wherein the first lever element is pivotally connected to a support via at least one first fixed bearing point, such that the first end and the second end are movable about a first pivot axis located on the first fixed bearing point.

[0012] - A first actuating element, which can be driven by a drive unit along a first linear stroke axis, wherein the first actuating element has a connecting section.

[0013] In this configuration, the connecting section of the first actuating element engages with the first end of the first lever element, and the second end of the first lever element engages with the vertical adjustment bearing point of the frame. This arrangement causes rotation of the first end, resulting from the linear movement of the first actuating element along the first linear stroke axis, to cause rotation of the second end of the first lever element about the first pivot axis, approximately in the opposite direction to the linear movement of the first actuating element along the first linear stroke axis. The movement of the second end of the first lever element is transmitted to the vertical adjustment bearing point of the frame, causing rotation of the frame about the horizontal axis.

[0014] and / or

[0015] The leveling device includes

[0016] - A second lever element having a lever axis and a first end and a second end opposite to each other along the lever axis, wherein the second lever element is pivotally connected to the support via at least one second fixed bearing point, such that the first end and the second end are movable about a second pivot axis located on the second fixed bearing point.

[0017] - A second actuating element, which can be driven by a drive unit along a second linear stroke axis, wherein the second actuating element has a connecting section.

[0018] The connecting section of the second actuating element engages with the first end of the second lever element, and the second end of the second lever element engages with the horizontal adjustment bearing point of the frame, such that the rotation of the first end caused by the linear movement of the second actuating element along the second linear stroke axis causes the second end of the second lever element to rotate about the second pivot axis in approximately the opposite direction to the linear movement of the second actuating element along the second linear stroke axis, wherein the movement of the second end of the second lever element is transmitted to the horizontal adjustment bearing point of the frame, causing the frame to rotate about the vertical axis.

[0019] As the terms "horizontal axis" and "vertical axis" implied, the horizontal axis is orthogonal to the vertical axis. Furthermore, the terms "horizontal" and "vertical" should be understood and considered to mean that the adjustment system is correctly installed in the vehicle.

[0020] It will be clear to those skilled in the art that after the frame is pivoted about the horizontal axis (meaning the frame changes to a vertical orientation), the vertical axis formed by the imaginary connecting line between the vertical adjustment bearing point and the fixed bearing point is not in the correct vertical position seen in the correct installation state of the adjustment system in the vehicle.

[0021] Alternatively, the drive unit can be an electric drive unit, a pneumatic drive unit, a hydraulic drive unit, or a manual drive unit (e.g., via a screwdriver).

[0022] Advantageously, the first fixed bearing point of the first lever element is constructed as two ball joints, wherein the two ball joints define the first pivot axis.

[0023] Advantageously, the second fixed bearing point of the second lever element is constructed as two ball joints, wherein the two ball joints define the second pivot axis.

[0024] Advantageously, the first pivot axis is parallel to the horizontal axis, or the first pivot axis is not parallel to the horizontal axis.

[0025] Advantageously, the first end of the first lever element has a horizontal offset to the vertical adjustment bearing point of the frame.

[0026] Advantageously, the vertical adjustment device includes an adjustable connecting element, wherein a second end of a first lever element is connected to a vertical adjustment bearing point of the frame via the adjustable connecting element, wherein the adjustable connecting element allows adjustment of the distance between the second end of the first lever element and the vertical adjustment bearing point along an x-axis orthogonal to the vertical and horizontal axes.

[0027] In order to adjust the distance between the second end of the first lever element and the vertical adjustment bearing point along the x-axis, the adjustable connecting element is advantageously composed of at least two parts connected by a threaded mechanism.

[0028] Advantageously, the leveling device includes an adjustable connecting element, wherein a second end of the second lever element is connected to a leveling support point of the frame via the adjustable connecting element, wherein the adjustable connecting element allows adjustment of the distance between the second end of the second lever element and the leveling support point along an x-axis orthogonal to the vertical and horizontal axes.

[0029] In order to adjust the distance between the second end of the second lever element and the horizontal adjustment bearing point along the x-axis, the adjustable connecting element is advantageously composed of at least two parts connected via a threaded mechanism.

[0030] Advantageously, the optically related component is at least one lamp module.

[0031] Advantageously, the first linear stroke axis is orthogonal to the vertical and horizontal axes.

[0032] Advantageously, the second linear stroke axis is orthogonal to the vertical and horizontal axes.

[0033] Advantageously, the support is a common support for both the vertical adjustment device and the horizontal adjustment device, or the support includes a first support and a second support that are separate from each other, wherein the first support holds the vertical adjustment device and the second support holds the horizontal adjustment device.

[0034] The objective can also be achieved by vehicle headlights that include at least one adjustment system according to the invention.

[0075] Adjust the load-bearing points VBP and HBP on the frame 50 so that the imaginary connecting lines between the adjustable load-bearing points VBP and HBP and the fixed load-bearing point FP form a triangle.

[0076] An imaginary connecting line between the vertically adjustable bearing point VBP and the fixed bearing point FP forms the vertical axis VA, while an imaginary connecting line between the horizontally adjustable bearing point HBP and the fixed bearing point FP forms the horizontal axis HA.

[0077] The adjustment system 10 also includes a bracket 40 for holding the vertical adjustment device 20 and the horizontal adjustment device 30, as well as the frame 50, wherein the frame 50 is mechanically connected to the bracket 40 via a fixed bearing point FP. The bracket 40 is a common bracket for the vertical adjustment device 20 and the horizontal adjustment device 30. However, the bracket 40 may also include a first bracket and a second bracket that are separate from each other, wherein the first bracket holds the vertical adjustment device 20 and the second bracket holds the horizontal adjustment device 30.

[0078] In the illustrated example, the vertical adjustment device 20 includes a first lever element 100 having a lever axis B1 and a first end 110 and a second end 120 opposite each other along the lever axis B1.

The first pivot axis PA1 is not parallel to the horizontal axis HA.

[0079] In addition, the first end 110 of the first lever element 100 has a horizontal offset HO to the vertical adjustment bearing point VBP of the frame 50.

[0080] Additionally, the vertical adjustment device 20 includes a first actuation element 200 that can be driven by the drive unit along the first linear stroke axis LA1 (for example, in...). Figure 2 and Figure 3As can be seen in the image, the first linear travel axis LA1 is orthogonal to the vertical axis VA and the horizontal axis HA. The first actuating element 200 has a connecting section 210, wherein the connecting section 210 of the first actuating element 200 engages with the first end 110 of the first lever element 100, and wherein the second end 120 of the first lever element 100 engages with the vertical adjustment bearing point VBP of the frame 50, such that the rotation of the first end 110 caused by the linear movement of the first actuating element 200 along the first linear travel axis LA1 results in a rotation of the second end 120 of the first lever element 100 about the first pivot axis PA1 in a direction substantially opposite to the linear movement of the first actuating element 200 along the first linear travel axis LA1, wherein the movement of the second end 120 of the first lever element 100 is transmitted to the vertical adjustment bearing point VBP of the frame 50, resulting in a rotation of the frame 50 about the horizontal axis HA, as shown in the image. Figure 2 The double arrows are used to indicate this.

The second fixed bearing points 330 of the second lever element 300 are constructed as two ball joints, wherein the two ball joints define the second pivot axis PA2.

[0084] Additionally, the leveling device 30 includes a second actuating element 400 that can be driven by the drive unit along the second linear stroke axis LA2 (which in Figure 2 and Figure 3(As can also be seen in the image), wherein the second linear stroke axis LA2 is orthogonal to the vertical axis VA and the horizontal axis HA. The second actuating element 400 has a connecting section 410, wherein the connecting section 410 of the second actuating element 400 engages with the first end 310 of the second lever element 300, and wherein the second end 320 of the second lever element 300 engages with the horizontal adjustment bearing point HBP of the frame 50, such that the rotation of the first end 310 caused by the linear movement of the second actuating element 400 along the second linear stroke axis LA2 causes the second end 320 of the second lever element 300 to rotate about the second pivot axis PA2 in a direction approximately opposite to the linear movement of the second actuating element 400 along the second linear stroke axis LA2, wherein the movement of the second end 320 of the second lever element 300 is transmitted to the horizontal adjustment bearing point HBP of the frame 50, causing the frame 50 to rotate about the vertical axis VA.

[0085] The horizontal adjustment device 30 may also include an adjustable connecting element 500 (not shown in the figure), wherein the second end 320 of the second lever element 300 is connected to the horizontal adjustment bearing point HBP of the frame 50 via the adjustable connecting element 500, wherein the adjustable connecting element 500 allows adjustment of the distance between the second end 320 of the second lever element 300 and the horizontal adjustment bearing point HBP along the x-axis X, which is orthogonal to the vertical axis VA and the horizontal axis HA.
