    Adjustment device for a motor vehicle headlight
    The invention relates to an adjusting device for adjusting, for example, for wasting of at least one optically relevant structural unit of a
    Motor vehicle headlight, which optically relevant unit is for example a light unit or at least comprises a light unit, and wherein the adjusting device comprises: -) a drive, in particular a linear drive, for adjusting, for example pivoting the unit, which drive is formed for example as an electric motor; -) At least one, preferably exactly one actuator, which is driven by the drive and moves substantially linear, wherein the at least one actuator is coupled to the assembly such that the assembly mechanically adjusted during a lifting movement of the actuating element, for example about its pivot axis is pivoted.
    Furthermore, the invention relates to a motor vehicle headlight with at least one adjustable, for example, pivotably mounted, opüsch relevant assembly, which adjustable by means of such adjustment, for. is pivotable.
    Analog motors are unsuitable for adjusting, for example, pivoting of an optically relevant structural unit, in particular for adjusting or pivoting one or more light units due to the incorrect position of such analog motors 2/29 -2- PI2646. This position inaccuracy has the consequence that the usually extremely small adjustment paths can not be precisely controlled.
    The drive for adjustment can often not be installed in the stroke direction of the actuating element due to lack of space. Furthermore, the drive must not have any or only small radial forces, i. Forces, which are not directed exactly in the stroke direction of the actuating element record.
    So far, the LWR drive (motor) is always connected via a bearing shell or directly to a support frame, which typically serves to Befesügen individual components of the headlamp. However, if the LWR motor is connected directly to the support frame or via a bearing shell, it must absorb all forces coming from the support frame.
    It is an object of the invention to provide an adjusting device with which one, several or preferably all of the above-mentioned problems can be eliminated.
    This object is achieved with an adjusting device mentioned above in that, according to the invention, the at least one actuating element is pivotably coupled to a rotary sliding element, which rotary sliding element is rotatable about an axis of rotation and slidably mounted along the axis of rotation, and wherein the at least one adjusting element on the Rotation sliding member engages outside the axis of rotation, so that a lifting movement of the at least one adjusting element is converted into a rotational movement of the rotary slide member, and wherein displacement means are provided, which convert a rotational movement of the rotary slide member in a linear movement of the rotary slide member along the axis of rotation. 3/29 -3- P12646
    By the invention, the movement of the drive, in particular the movement of the actuating element by the rotary sliding element in an adjusting movement, e.g. a pivoting movement of the adjustable, e.g. be pivoted pivotable component. This makes it possible to position the drive easier. In addition, the amount of adjustment, e.g. Pivoting is no longer realized by the extent of the lifting movement of the actuating element but by the displacement elements, so that inaccuracies in the lifting movement of the actuating element no longer fall into the weight. The sliding elements can easily be formed with sufficient accuracy to ensure proper adjustment, e.g. To realize pivoting of the unit.
    It is particularly advantageous if the direction of movement of the actuating element is substantially normal to the axis of rotation of the rotary sliding element. In this way, the drive can be positioned laterally next to the rotary slide element and not behind it, so that the available space can be optimally utilized.
    In a specific embodiment of the invention, it is provided that the axis of rotation is normal to the pivot axis of the at least one structural unit.
    In order to enable a height adjustment of the generated light image, it is further provided that the United pivot axis is a horizontal axis.
    In a concrete, mechanically robust and reliably realizable embodiment of the invention, it is provided that the displacement means comprise at least one guideway and at least one engagement element, which is guided in the at least one guideway. 4/29 - 4 - P12646
    By appropriate shaping of the guide track, it is possible to set how far the rotational sliding element moves linearly, thus the extent of the adjusting movement, e.g. the United wenkbewegung the adjustable, for example, pivotable unit can be adjusted.
    In particular, it is advantageous if the guideway at least two "parallel", i. lying in parallel planes guideway portions which are normal to the axis of rotation, and wherein adjoining guideway sections jeweüs are each connected by a sloping portion, so that the two interconnected Guiding Scheilabschitte are offset relative to each other and with respect to the axis of rotation. The notion of "parallel planes" is discussed in more detail below with reference to the description of the figures below.
    As a result of this configuration, the rotary sliding element can be moved in discrete steps from the parallel guide track section to the next, thus realizing an adjustment or swiveling about discrete steps. Depending on the number of parallel guideway sections, a corresponding number of adjustment or Ver can be achieved wenkschritten.
    Due to the special orientation of the parallel guideway sections, it is also ensured that even with an action of high external forces or in the event of a failure of the drive, the rotary sliding element remains in its last occupied position and thus an intentional, undesired adjustment occurs. 5/29 -5- PI2646
    In a specific embodiment of the invention, it is provided that the at least one guideway is arranged on the rotary sliding element or on a bearing element, which is arranged stationary with respect to the rotary sliding element.
    At this bearing element, the rotary slide member is rotatably and slidably mounted.
    Alternatively, it can be provided that the at least one engagement element is arranged on the rotary slide element or on a bearing element which is stationary with respect to the rotary slide element.
    But it can also be a "mix" be provided in these variants, in which e.g. one (or more) engaging member (s) and one (or more) guideway (s) are disposed on the bearing member, and the respective associated guideways and engaging members are disposed on the rotary slider.
    It has proven to be particularly advantageous in terms of construction if the at least one engagement element and / or the at least one guideway is arranged on a circumferential region of the rotary sliding element.
    Furthermore, it is then advantageously provided that to the at least one engaging element corresponding guideways and / or to the at least one guideway corresponding engaging elements are arranged on a circumferential region of the opposite region of the bearing element.
    It is also advantageous if the bearing element has a two-part construction of a first and a second bearing component. This will assemble the 6/29 -6 PI2646
    Adjusting device, in particular the storage of the rotary rotary element in the bearing element simplified.
    In particular, it is advantageous in this context if the division of the bearing element in the region of the at least one guideway runs. In this way, the engagement elements, which are arranged in this case on the rotary slide member, particularly easy to be arranged in the assembly in the guideways.
    The guideways are arranged, for example, as recesses, preferably in the bearing element, in which recesses each preferably an engagement element is guided.
    It is particularly advantageous in the adjusting device according to the invention, when the coupling between the at least one adjusting element and the rotary sliding element by means of a ball-head-like coupling element which engages in a corresponding receptacle, and wherein either the coupling element or the receptacle on the actuating element and either the recording or the coupling element are arranged on the rotary sliding element, takes place, wherein the receptacle is designed such that the coupling element is displaceable in a direction transverse to the adjustment direction of the adjusting element in the receptacle, in particular parallel to the direction of the axis of rotation of the rotary sliding element.
    In a specific embodiment, it is provided that the drive is an analog motor. The invention is particularly well suited to the use of analog motors, since their disadvantages are eliminated by the construction according to the invention and analog motors are generally much cheaper than digital motors. 7/29 -7- PI2646
    Of course, in the context of the invention but also digital motors can be used.
    In the context of this invention is here as "digital". Motor or drive to understand a drive, which is provided with its own control electronics, which preferably also receives feedback on the selected position of the drive. Under "analogue" Motor or drive is understood to mean a drive which does not have such a control electronics, but is controlled, for example, with a potentiometer by means of applied voltage.
    Accordingly, such an analog drive is much cheaper, but also much less accurate than a digital drive.

    The figures show various perspective views and an exploded perspective view of an adjusting device 1 (as well as details of this
    Adjustment device) for a motor vehicle headlight, which has a pivotable, visually relevant structural unit. In the present example, this is a lighting unit 100. Such a lighting unit typically consists of an assembly consisting of one or more light sources, one or more light-shaping elements, such as a reflector, lens, aperture etc. Figure 1a shows a part such a lighting unit 100, pivotally mounted about a horizontal pivot axis H.
    In principle, however, the optically relevant structural unit may also be an individual part of a vehicle headlight or a lighting unit, such as a reflector, a lens, a light source, diaphragm arrangement, etc., or the optically relevant structural unit comprises one or more such components or one or more a plurality of light units on a common carrier, which carrier is pivotable. 9/29 -9- PI2646
    Furthermore, it is noted at this point that in the example shown here, the adjustments of the optically relevant component in the form of a pivoting of this component is shown about an axis. However, the construction according to the invention is also suitable for a general adjustment movement of the optically relevant component, for example in displacement of the optically relevant component.
    For example, in this context, the optically relevant component may be a dipped-beam / high-beam shader, which may be e.g. at high beam on and extends at dipped beam. It can be realized with the device according to the invention, for example, a variable spacing between the light source (LED) and reflector and / or lens.
    The adjusting device 1 for pivoting the optically relevant structural unit has a drive 2, in particular a linear drive approximately in the form of an electric motor. In particular, an analog drive can be used in the present invention.
    Furthermore, the adjusting device 1 comprises an actuating element 3, which is driven by the drive 2 and moves in a substantially linear manner. The actuator 3 is either part of the drive 2 or connected to this.
    The actuator 3 is coupled to the assembly 100 such that the assembly 100 is pivoted at a stroke of the actuator 3 about its pivot axis H.
    For this purpose, the adjusting element 3 is pivotally coupled to a rotary slide member 4, which rotary slide member 4 is rotatable about a rotation axis X and slidably mounted along the rotation axis X. 10/29 -10- PI2646
    The bearing of the rotary sliding element 4 takes place in a bearing element or bearing component 7, which preferably, as explained later, a two-part construction of two components 7a, 7b. In order to allow a rotatable about the axis X and along this axis X displaceable mounting of the rotary slide member 4, for example, provided that the bearing element 7 has a cylindrical opening 7a ', in which the rotary slide member 4 with a correspondingly shaped, corresponding Cylinder 4c engages, so that a rotation and displacement movement is possible (see also Figure 4).
    The adjusting element 3 acts on the rotary sliding element 4 outside of the axis of rotation X, so that a lifting movement of the adjusting element 3 is converted into a rotational movement of the rotary sliding element 4.
    In the specific embodiment shown, it is provided that the coupling between the actuator 2 and the rotary slide member 4 by means of a ball-head coupling element 3a, which engages in a corresponding receptacle 4b, wherein the coupling element 3a on the actuator 2 and the receptacle 4b the rotary sliding element 4 are arranged. The receptacle 4b is designed such that the coupling element 3a in a direction transverse to the adjustment of the adjusting element 2, in particular parallel to the direction of the axis X in the receptacle 4b is displaceable.
    The receptacle 4b thus forms a parallel to the axis X extending guide for the actuator, so that the rotary slide can move freely along the axis X and at the same time the actuator can cause the rotary slide to a twisting motion. 11/29 -11- P12646
    A lifting movement of the adjusting element 3 is thus converted into a rotational movement of the rotary sliding element 4, which is displaced along the axis X by the rotational movement, as discussed below. The rotary sliding element 4 has a connection point 10, for example in the form of a ball seat, to which the optically relevant component is directly or indirectly (via one or more intermediate elements) connected to a corresponding counterpart, so that a displacement of the rotary sliding element 4 along the axis X leads to a pivoting of the optically relevant component about the axis H.
    Thus, the rotational movement of the rotary slide member 4 is converted into a sliding movement of the rotary slide member 4 along the axis X, corresponding displacement means 5, 6 are provided which rotational movement of the rotary slide member 4 in a linear movement of the rotary slide member 4 along the axis of rotation Implement X.
    As can be seen in particular from FIGS. 4-8, in the embodiment shown, the displacement means comprise guide tracks 5 which are arranged on the bearing element 7.
    Furthermore, the displacement means comprise a number of engagement elements 6 corresponding to the number of guideways 5, which are arranged on the rotary sliding element 4, specifically on a circumferential area 4 a of the rotary sliding element 4. Depending on an engaging element 6 engages in an associated guide track 5 and by the special shaping of the guideways, preferably in addition also the engaging elements, the rotational movement of the rotary slide member 4 is converted into a linear movement, i. the rotational movement is superimposed by a linear movement. 12/29 -12- PI2646
    By appropriate shaping of the guideway can be adjusted, as far as the rotational slide member moves linearly, thus, the extent of the pivoting movement of the pivotable assembly can be adjusted.
    In particular, it is advantageous, as can be clearly seen in FIGS. 6-8, when a guideway 5 has at least two guideway sections 5a, 5b, 5c lying in parallel planes, these planes running normal to the axis of rotation X, and the planes are offset in the direction of the axis of rotation X to each other.
    Specifically, in the present example, this means that the guideway has an upper and a lower contour, between which an engagement element is guided. The term "plane" is here virtually an idealization and refers for example to a center line between the contours, since the guideway itself has an extension along the axis X. The term "plane" Thus, it should serve primarily to describe the orientation / position of the guideway or the individual sections thereof.
    Adjacent guide track sections 5a, 5b, 5c are each connected to one another by an obliquely extending section 5d, 5e, so that the two guide track sections 5a, 5b; 5b, 5c relative to each other and with respect to the axis of rotation X are arranged offset and the engagement element 6 can slide from a position along the guide track in a subsequent, offset position, whereby the rotary slide member 4 is linearly displaced along the axis X. Guideway and corresponding engaging element are so adapted to each other by the shape that the engaging element can move along the guideway in the direction of the X-axis but only when sliding over into an adjacent position as a result of rotation of the rotary sliding element 4 is possible. Without twisting the 13/29 -13- PI2646
    On the other hand, the rotational sliding element 4 can not move the engaging element 6 in the guideway in the X direction.
    As a result of this configuration, the rotary sliding element can be moved in discrete steps from the parallel guide track section to the next, thus realizing pivoting about discrete steps. Depending on the number of parallel guideway sections, a corresponding number of Verschwenkschritten be realized.
    In the present embodiment, an engaging element 6 has two "parallel " Sections 6a, 6b corresponding to the sections 5a - 5c of the associated guide track 5, so that two different positions of the engaging element 6 can be realized. The two rectilinear sections 6, 6b are interconnected by an oblique section 6c.
    If the engaging element were designed only as a pin, 3 positions could be realized in this example. If more than three sections 5a-5c are provided, several positions of the engagement element can also be realized.
    A simple variant of the invention is outlined in FIG. 9, where the engaging element is designed as a pin 6, which is guided in a guide track 5 with two parallel sections 5a, 5b, which are connected to one another by a bevelled section 5d. With this variant, two adjustment positions can be realized.
    The special alignment of the parallel guideway sections ensures that even when exposed to high external forces or in the event of a failure of the 14/29 -14-P12646
    Drive the rotary slide remains in its last occupied position and so an imbought, imerwünschtes adjustment occurs.
    In particular, when using an engaging element as shown in Figures 6-8 represents this stability is further increased.
    As can be seen from the figures, in the illustrated embodiment of the invention, the axis of rotation X runs normally on the pivoting axis H of the lighting unit 100.
    In order to enable a Höhenver position of the generated photo, it is further provided that the United pivot axis H is a horizontal axis.
    The direction of movement of the actuating element 3 is substantially normal to the axis of rotation X of the rotary sliding element 4. In this way, the drive can be positioned laterally next to the rotary slide member and not behind it, so that the available space can be optimally utilized.
    The drive 2, which is connected to the control element 3 (or wherein the control element 3 is part of the drive 2) is connected to a housing, not shown, of the vehicle headlight. In addition, the drive 2 in the bearing element 7, which receives the rotary slide member 4, stored. For this purpose, this has, for example, as shown in the figures, a drive bearing portion 7c with a corresponding receptacle 7d for receiving a portion of the drive 2.
    It is also advantageous if the bearing element 7 as shown in the figures provides a two-part construction of a first and a second bearing member 7a, 7b. 15/29 -15- PI2646
    As a result, the assembly of the adjusting device, in particular the mounting of the rotary rotary element in the bearing element is simplified.
    In particular, it is in this context advantageous if the division of the bearing element 7 in the region of the guideways 5 extends. In this way, the engagement elements, which are arranged in this case on the rotary slide member, particularly easy to be arranged in the assembly in the guideways.
    With the bearing element 7, the rotary slide member 7 is fixed to the housing of the headlamp.
    With the invention it becomes possible to decouple the drive mechanically, i. he does not have to absorb any forces from the light module.
    The drive can be installed at 90 ° to the desired stroke direction of the rotary sliding element. About the displacement elements, the positioning inaccuracy of the drive can be compensated.
    If the drive fails, the system remains mechanically stable, i. there is no undesirable adjustment of the optically relevant component.
    The adjustment takes place in discrete steps. 16/29
