    Adjustment system for a vehicle headlight
    The invention relates to an adjustment system for a vehicle headlight for adjusting at least two optically relevant components of the vehicle headlamp, wherein the optically relevant components each at a fixed bearing point about a first and a second axis, preferably about a vertical and a horizontal axis, are pivotable the first and the second axis are oriented normal to each other, the adjustment system comprises a first adjusting device, which is adapted to move an adjusting exclusively along a third axis, the adjusting arm engages on a the optically relevant component respectively associated first adjustment bearing point, wherein the fix Bearing point and the respective first adjustment bearing point form the respective first axis. Furthermore, the invention relates to a vehicle headlight with an adjustment system for adjusting at least two optically relevant components.
    Adjustment systems for vehicle headlights are used for setting or for aligning a light image generated by the vehicle headlight. The adjustment system acts on an optically relevant component. Adjusting systems known from the prior art usually have a servo motor which has a linearly displaceable adjusting element which acts on an adjusting bearing point of an optically relevant component. The optically relevant component is at least pivotally mounted about an axis, wherein in modern vehicle headlights typically two axes are provided. The two axes can be oriented normal to each other, with a fixed bearing point and two adjustment La-gerpunkte are provided, which together form a so-called Verstelldreieck. This makes it possible to pivot an optically relevant component, for example, in horizontal as well as in the vertical direction, so that a horizontal and vertical adjustment of the light image is made possible. In this case, an adjustment device is usually assigned to each optically relevant component, whereby restrictions exist with regard to the design and the space requirement of the vehicle headlight or the spatial arrangement of the optically relevant components. A front see several optically relevant components is therefore difficult to achieve and also involves the problem in that the setting of the individual optically relevant components to each other can be tuned only with difficulty. It is therefore an object of the invention to provide an adjustment system for vehicle headlights for adjusting at least two optically relevant components, which can be installed to save space and withstand high mechanical loads, can be easily installed, allows the most accurate positioning of the optically relevant components and cost and efficient works.
    This object is achieved with an adjustment system for a vehicle headlamp of the type mentioned, in which according to the invention the adjusting arm at least two at least in the direction of the first axis and / or the second axis y spaced-apart guide openings, in which parallel to the third axis x oriented guide elements are received, wherein the guide elements are secured in the vehicle headlight against displacement in the direction of the first and second axis.
    Thanks to the invention, it is possible to provide an adjustment system for vehicle headlights, which is inexpensive and easy to implement, has a robust mechanical structure, withstands high mechanical loads, and can be installed particularly quickly in a vehicle headlight. The guide apertures spaced apart from one another in the direction of the second axis permit a particularly rigid guidance of the adjustment arm along the guide elements, whereby shock and vibration processes, such as those occurring in a vehicle headlight, especially in a motor vehicle, do not lead to any lasting change in a spruce image a vehicle headlamp with an adjustment system according to the invention lead.
    The axes relate to the vehicle headlight or on a built-in a motor vehicle headlight. An optically relevant component is, for example, a spruce module, a spruce module unit, which consists of one or more spruce modules, or one or more components of such a spruce module or spruce module unit, this component or these components Have an influence on the spruce distribution generated by the spruce module or by the spruce module unit.
    With a spruce module, a certain spruce distribution, such as a high beam distribution, a dimmed light distribution, such as a low beam, a fog light distribution, etc., can be generated, or a light module is used in the context of a light module unit to produce a part of such a light distribution.
    An (optically relevant) component of a light module or a light module unit, which has an influence on the light distribution produced by the light module or by the light module unit, is generally a component, such as a light module. a reflector, a lens, a diaphragm, a light source or a light source arrangement or other light-shaping means, such as light guides, light guide etc.
    For adjusting the light image and / or for generating dynamic light distributions, for example for generating a dynamic cornering light and / or a dynamic headlamp leveling, it is often provided that an optically relevant component is arranged around one, preferably around two axes, e.g. a horizontal axis and a vertical axis is ver pivoted.
    Under the term "optically relevant component " In the context of this description, therefore, in particular one, two or more diaphragms (arrangements), light sources, in particular LED light sources, reflectors, lenses and / or entire light modules or assemblies, etc. are understood.
    In this case, it may be favorable if the fixed bearing point and a second adjusting bearing point arranged on the respective optically relevant component form the respective second axis.
    In order to allow a particularly simple guidance of the guide elements, it can be provided that the at least two guide openings are oriented parallel to the third axis.
    A particularly stable guidance of the adjusting arm can be achieved by the adjusting arm having at least three guide openings, wherein two guide openings are spaced apart in the direction of the third axis and one of the guide elements is received in two parallel to the third axis oriented guide openings. Alternatively, exactly three, four or more than four openings could be provided.
    In order to compensate for dimensional inaccuracies during installation and during production of the adjustment system, it may be favorable if at least one of the guide openings in the direction of the first axis z and / or the second axis is widened, in particular those guide openings which are arranged to a guide element, in Direction of the first axis and / or the second axis are extended.
    A particularly simple Relati who position between individual with the adjustment engaged optically relevant components can be made possible when the first adjustment bearing point of an optically relevant component is arranged on the adjusting arm widening adjusting screw, wherein the adjusting screw is oriented in the direction of the third axis , A rotation of the adjusting screw thus leads to a shift of the first adjustment La-gerpunktes. It may be particularly advantageous if the adjusting screw has a ball head, wherein the first adjusting bearing point is arranged on the ball head.
    In a particularly simple embodiment of the invention, the guide elements are formed as elements with a cylindrical lateral surface, in particular as a cylindrical bolt.
    In order to prevent blocking of the guide elements within the guide openings, it may be provided that the guide openings are enlarged in the region of the opening entrance. The opening is rounded, for example, so that a continuous transition between the opening input and the inner of the opening is created. A degree left on the guide opening of the adjustment arm caused by a manufacturing process (e.g., a casting process) thereby has no adverse effects on the sliding behavior of the guide member.
    In order to enable a stable connection of the guide elements with a vehicle headlight, it can be provided that the guide elements are held in a firmly connected to the vehicle headlight support member.
    In particular, it may be advantageous if the optically relevant components are each connected to a second adjusting device, wherein the respective second adjusting device acts on a second adjusting bearing point on the optically relevant component. As a result, a pivoting movement about the first axis can be selectively influenced or predetermined.
    In order to enable automatic pivoting of the optically relevant components about the second axis, it may be provided that the first adjusting device has a servomotor for displacing the adjusting arm along the third axis.
    It may also be favorable if the first adjusting device has a manually operable adjusting unit for manual adjustment of the displacement of the adjusting arm along the third axis.
    In the following, the invention will be explained in more detail with reference to an exemplary embodiment shown in the figures and not limiting. It shows

    1 shows a perspective view of an adjustment system 1 of a vehicle headlamp for adjusting at least two optically relevant components 2a and 2b. In the exemplary embodiment shown, two optically relevant components are shown, which are, for example, spruce sources accommodated in a housing. Of course, the number of optically relevant components can also be three, four or more. The optically relevant components each have a fixed-fagering point FP, which is arranged, for example, on a ball joint, and are pivotable about a first axis z and a second axis y, preferably about a vertical and a horizontal axis, wherein the first and the second axis z and y are oriented normal to each other. The adjustment system 1 also has a first adjustment device 3, which is set up to move an adjustment arm 4 along a third axis x. The displacement is secured against movement in the direction of the first and second axes z and y and therefore takes place exclusively in the direction of the third axis x. The first adjusting device 3 can be realized as a conventional, known from the prior art adjusting device, which typically has a servomotor 3a with a linearly displaceable actuator element and a superimposed adjusting unit 3b. In this case, for example, an automatic adjustment by means of the servo motor 3a, wherein a basic adjustment via the adjusting unit 3b can be made, which couples with, for example via a bevel gear on the actuator element and is set up for linear displacement of Verstellarms 4. Corresponding adjusting devices have become known, for example, from DE 19619586 B4, US Pat. No. 6,773,153 B2 or EP 1675751 B1. The displacement of the adjusting arm 4 acting on the first adjusting bearing point PI can thus be effected by a manual basic adjustment by means of the adjusting unit 3b as well as automatically by the servomotor 3a. The adjusting arm 4 engages a first adjusting bearing point PI belonging to the optically relevant component 2b, the fixed bearing point FP and the respective first adjusting bearing point PI forming the respective first axis z. The adjusting 4 know in Figure 2 shown in the direction of the second axis y spaced apart guide openings 5 (alternatively, the guide openings could also be spaced from each other in the direction of the third axis z) in which parallel to the third axis oriented guide elements 6 are added, said the guide elements 6 in the vehicle headlight are secured against displacement in the direction of the first and second axes z and y (and preferably in the direction of the third axis x). The guide elements 6 are held in a holding element 7 shown in Figure 1, wherein the support member 7 fixed to the vehicle headlight on a vehicle headlight associated frame or housing 9 (see FIG. 6) connected, in particular screwed is.
    Each optically relevant component 2a, 2b know in the embodiment shown a second adjustment bearing point P2 on which a in the figures is not asked second adjustment acts (which may be analogous to the first adjustment 3), wherein the second adjustment bearing point P2 together with the fixed bearing point FP forms the respective second axis y. The fixed bearing points can preferably be arranged on at a ball joint, wherein the adjusting bearing point PI is arranged in a joint, the movement play in the direction of the first axis z permits and the second adjusting bearing point P2 is arranged in a joint, the Movement in the direction of the second axis y allows (this can be made possible, for example, by correspondingly shaped bearings with bearing shells). The first adjusting device 3 engages in a coupling section 4b of the adjusting arm 4, so that a displacement of the adjusting arm 4 by means of an actuator element of the adjusting device 3 is possible (for more details see FIG. 4).
    Figure 2 shows a perspective view of individual components of the adjustment system 1 in the disassembled state. It can clearly be seen that the at least two guide openings 5 are oriented parallel to the third axis x. In the exemplary embodiment shown, the adjustment arm 4 has three guide openings 5, wherein two guide openings 5 are spaced apart from one another in the direction of the third axis and are adapted to receive one of the guide elements 6. Individual guide openings 5 may be formed within arranged on the adjustment arm 4 cylindrical tubes or eyelets. Thus, the guide openings 5 may be circular or in the form of a widened in the direction of the second axis y elongated hole, with the guide openings 5 extend to the opening entrance to compensate in the manufacturing process of the adjustment 4, for example, incurred residues, especially a ridge and to allow a smooth movement of the guide elements 5 within the guide openings 6 (see Fig. 7).
    In order to enable a particularly simple adjustment of individual optically relevant components 2a, 2b, which are controlled by the common adjustment 4, to one another, it can be provided that at least the adjustment bearing point PI of an optically relevant component 2b on an adjusting screw 4 widening adjustment 8 is arranged. A displacement of the adjusting screw 8 in the direction of the third axis x can be achieved by a rotation of the adjusting screw 8 about the screw axis, whereby a displacement of Ver-stell-bearing point PI of the optically relevant component 2b in relation to the other optically relevant component 2a achieve leaves. The adjusting screw 8 preferably has a ball head on which the adjusting bearing point PI is arranged. The guide elements 6 are designed as elements with a cylindrical lateral surface, preferably as cylindrical bolts.
    In the embodiment shown, the adjusting arm 4 engages two first adjusting bearing point PI, wherein an adjusting bearing point PI is arranged within a cup-shaped receptacle of the adjusting arm 4 and the other first adjusting bearing point PI is formed on the ball head of the adjusting screw 8.
    Figure 3 shows a front view of individual components of the adjustment system 1 according to the invention in the disassembled state. It can be seen that one of the guide openings 5 has an extension in the direction of the second axis y and is thus designed as a slot. The movement of the associated guide element 6 is therefore limited only in the direction of the first axis z by this guide opening 5. This has the advantage that manufacturing inaccuracies of the adjustment 4 or the support member 7 can be compensated.
    FIG. 4 shows a front view of the adjustment system 1 according to the invention according to FIGS. 1 to 3 in an assembled state. It can be seen that the first adjustment device 3 or an actuator element of the first adjustment device engages in the coupling section 4b of the adjustment arm 4 and is connected to it by way of example with a screw connection. The coupling is embodied such that a linear movement along the third axis x of an actuator element assigned to the first adjustment device 3 leads to a linear displacement of the adjustment arm 4 along the third axis x.
    Figure 5 shows a sectional view of the adjustment system 1 according to the section line A-A.
    FIG. 6 shows a representation of a vehicle headlight housing or frame 9, in which guide rails 9a for receiving the retaining element 7 are shown. The support member 7 is thereby inserted into the guide rails 9a and connected to the vehicle headlight housing or frame 9, preferably screwed. By means of the invention, it is possible that the adjustment system 1 can already be completely pre-assembled and subsequently connected to the vehicle headlight housing or frame 9.
    FIG. 7 shows a sectional view of a holding element 7 with a guide element 6 received in the guide opening 5. Therein, two opposite extensions of the opening entrance are clearly discernible, by means of which the guiding element 6 slides as smoothly as possible.
    In view of this teaching, the invention may be modified in any manner known to those skilled in the art and is therefore not limited to the embodiment shown. Also, individual aspects of the invention can be taken up and largely combined with each other. Essential to the invention of the underlying idea, by a person skilled in the knowledge of this description can be performed in a variety of ways and still be maintained as such.
