    Adjustment device for a vehicle headlight
    The invention relates to an adjusting device for adjusting an optically relevant component of a vehicle headlamp, having an actuator element displaceable by means of a servomotor along a displacement axis, a transmission element connected to the actuator element for displacement along the displacement axis and rotatably mounted about the displacement axis, one with the Transmission element by means of a compound in mechanically engaging actuator, wherein the adjusting element is adapted to engage the optically relevant component, and arranged for rotation of the transmission element, about the Verschubachse rotatably mounted rotary member.
    Adjusting devices for adjusting optically relevant components of headlights, such as light sources, reflectors and / or lenses allow adaptation of the light image generated by the headlight to vorgebebene requirements. This makes it possible to compensate deviations from target specifications, which are determined, for example, after an installation procedure of the headlight in a motor vehicle, subsequently by using an adjusting device. A typical task of adjusters is to adjust the headlamp range of a headlamp, and this technical field is particularly defined by the term "headlamp leveling". has become known.
    Adjusting devices, which are used for example in conventional headlamp leveling systems, usually have a displaceably mounted servo motor with an actuator element, wherein the actuator element is adapted to attack an optically relevant component of the headlamp. The servomotor allows an automatic adjustment of the optically relevant component. For basic adjustment of such an adjustment device often an adjustment mechanism is provided, which is adapted to move the servomotor together with the actuator element along slideways. In this case, the servomotor, for example, with a driven via a bevel gear spindle dergestalt in such a mechanical engagement, so that rotation of a held in an outer region of a headlight bevel gear spindle is set in rotation, thereby displacing the actuator together with the actuator element. In this way, a basic adjustment of a vehicle headlight can be made in a very simple manner.
    A disadvantage of known adjusting devices is that the adjusting mechanism for the basic adjustment of the servomotor together with the actuator element requires a complex production, since this consists of several components in which forces acting therein are often deflected several times. The servomotor is held in slideways, which allow a displacement of the servomotor. Occurring shear forces can lead to tilting of the servo motor and / or the actuator element under certain circumstances, which is why the slideways may need to be additionally lubricated.
    It is therefore an object of the invention to provide an adjusting device for adjusting an optically relevant component of a vehicle headlight, which allows a robust, efficient and cost-effective adjustment of the optically relevant component.
    This object is achieved with an adjusting device according to the aforementioned type, in which according to the invention, the connection connecting the transmission element with the adjusting element is adapted to convert a rotational movement of the transmission element in a sliding movement of the actuating element along the Verschubachse.
    In this case, the adjusting element, the transmission element and rotary element are designed as separate components. The rotary member is not displaceable along the thrust axis in contrast to the transmission element, but only rotatable about the thrust axis. A sliding movement of the actuating element along the Ver thrust axis can therefore take place relative to the rotary member. In addition, the connection element connecting the transmission element with the actuating element is adapted to convert a rotational movement of the transmission element into a sliding movement of the actuating element along the displacement axis relative to the transmission element. The actuating element thus acts on an optically relevant component, so that a movement of the actuating element can be converted into a changed orientation of the optically relevant component. The optically relevant component may be, for example, diaphragms, light sources, reflectors, lenses, entire light modules or assemblies, etc. It is also possible that an optically relevant component is accommodated in an adjustment mechanism, for example in a pivotally mounted frame. Under the expression that "the actuator is adapted to attack the optically relevant device". Therefore, an arrangement is understood in which the actuating element acts indirectly (for example via an adjustment mechanism) on the optically relevant component.
    Thanks to the invention, it is possible to obtain a particularly robust and finely adjustable adjusting device, which is inexpensive to implement and largely minimizes transverse forces occurring within the adjustment. The servomotor can be installed stationary in a housing. A basic adjustment of the actuator can be done without a displacement of the servo motor, which can be dispensed with additional arranged in a housing slideways and the reliability of the adjustment device according to the invention is particularly high. Adverse effects due to manufacturing inaccuracies and / or thermal expansion of participating components are also minimized.
    In an advantageous embodiment, it may be provided that the adjusting element, the transmission element and the rotary element are arranged coaxially to the Verschubachse. This allows a particularly efficient power transmission and increases the rigidity of the adjustment.
    In a particularly simple and efficient further development of the invention, the connection connecting the transmission element to the control element is designed in the form of a threaded connection, wherein the transmission element has a threaded section and the control element has a counter-threaded section corresponding thereto.
    In addition, it is advantageous if the actuating element has guide means which secure the adjusting element against rotation about the Ver thrust axis. A rotational movement of the transmission element can thus be converted particularly reliably and accurately into a sliding movement of the actuating element.
    In order to limit the maximum stroke of the actuating element with respect to the transmission element and to avoid an undesired release of the connection of the actuating element with the transmission element, it may be advantageous if the rotational movement of the transmission element is limited by means of mechanical stops.
    A particularly robust and simple construction of an adjusting device can be obtained by the servomotor, the actuator element, the transmission element, the rotary member and the actuator are at least partially taken within a housing.
    It is particularly advantageous if the housing is formed substantially half-shell-shaped. This allows a particularly simple assembly of the adjusting device according to the invention. In particular, it may be provided that the rotary element is mounted in a half-shell bearing arranged within the housing.
    In a particularly advantageous embodiment of the invention, the actuating element on guide means which secure the actuator against rotation about the Verschubachse, wherein the guide means engage in the guide means corresponding, disposed within the housing recesses and / or projections.
    In order to allow a particularly favorable installation of the adjusting device, it may be provided that the servomotor and the housing each have at least one, preferably two fastening tabs, wherein the mounting tabs of the housing and the servomotor overlap each other in an installed state of the adjustment.
    In a particularly simple embodiment, the transmission element and / or the actuator element has a latching device for connecting the transmission element to the actuator element.
    In a particularly advantageous embodiment of the invention, the transmission element may be at least partially received in a substantially circular concentric to the Ver thrust axis arranged opening of the rotary member. As a result, a particularly compact construction of the adjusting device according to the invention is possible. In an advantageous development, the transmission element in this case has elastic means, which are arranged on the circumference of a fictitious concentric to the Ver thrust axis arranged circle and extend along the Verschubachse, wherein the elastic means have projections which are adapted to be arranged within the opening corresponding To intervene recesses. In this way, a torque limit can be realized. If, for example, the maximum stroke of the actuating element with respect to the transmission element is reached, a mechanical overloading of its connection can be prevented by deforming the elastic means starting from a defined torque in such a way that they slide out of the corresponding depressions and produce a "spin" effect. enable the rotary member with respect to the transmission element. In a particularly simple and effective development, the elastic means can be formed tongue-like, wherein the projections are designed in the form of axially parallel pin and the corresponding recesses are designed as axially parallel grooves.
    In a particularly simple embodiment of the invention, the actuating element has a coupling region for engagement with the optically relevant component of a headlight. It is particularly advantageous if the coupling region is formed by a ball head arranged concentrically to the displacement axis. This allows a particularly efficient and robust power transmission to the optically relevant component.
    In a particularly favorable embodiment of the invention, the rotary element has a toothing, in particular a ring gear, in a region located outside the opening. A mechanical intervention in the rotary element is thus particularly easy. In particular, it may be provided that a bevel pinion is provided for engagement in the toothing. It is particularly advantageous if the axis of rotation of the bevel pinion is oriented substantially normal (at right angles) to the Verschubachse. Thus, e.g. an aligned on a horizontally oriented Verschubachse rotary member are driven by a vertically oriented bevel pinion. This is of particular importance in headlamps because e.g. a simple access or a simple adjustment of the adjusting device is particularly desirable, in this configuration, for example, a particularly simple adjustment of adjusting devices with horizontal Verschubachse over an upper surface of a spotlight housing can be made possible.
    In a particularly advantageous embodiment of the invention can be provided that the servo motor, the actuator element, the transmission element, the rotary member and the actuator are at least partially accommodated within a housing, wherein the bevel pinion is mounted in the housing.
    In order to shield the adjusting device as efficiently as possible from the environment and, for example, to prevent unwanted ingress of water into the adjusting device and in particular into a headlight housing accommodating the adjusting device, it can be provided that the bevel pinion is enclosed by means of a sealing ring located above the housing.
    In a particularly favorable embodiment of the invention, the adjusting element is made of PA 6.6 (polyamide 6.6). The actuator has thereby particularly good sliding properties, which can be dispensed with lubrication between the transmission element and the actuator.
    Furthermore, it can be provided that the rotating element is made of PBT (polybutylene terephthalate) with a weight fraction of about 20 to 40% glass fiber. The rotary element is therefore particularly robust.
    In addition, it can be provided that the transmission element from POM (Polyoxymethy-len) is made. The transmission element thus withstands high mechanical stress under high elasticity.
    Furthermore, it can be provided that the housing is made of PBT (polybutylene terephthalate) with a weight fraction of about 20 to 40% glass fiber. The housing is therefore particularly strong and withstands high mechanical stresses.
    In particular, it may be provided that the bevel pinion of PA 6 (polyamide 6) is produced with a weight fraction of about 20 to 40% glass fiber. The bevel pinion is therefore particularly robust and at the same time inexpensive to produce.
    Furthermore, the invention relates to a vehicle headlight with an adjusting device according to the invention.

    FIG. 1 shows a perspective view of an adjustment device 11 according to the invention. The adjustment device 11 comprises therein an actuating motor 1 which is accommodated in a housing 2, an adjustment element 3 protruding at least partially out of the housing 2. The adjusting device 11 is for setting an optically relevant component (not shown in the figures) of a vehicle headlamp, wherein the adjusting device 11 by means of a servo motor 1 along a Ver x sliding actuator x 7 movable element 7 (see, for example, Fig. 3), one with the Actuator element 7, arranged for displacement along the Verschubachse x and about the Verschubachse x rotatably mounted transmission element 8 (see, for example, Fig. 3), the actuator 3 and a set up for rotation of the transmission element 8 to the Verschubachse x rotatably mounted rotary member 6 (see eg Fig. 2 and 3). The actuator 3 is in mechanical engagement with the transmission element 8 by means of a connection 8b and 3b (see for example Fig. 3) and is adapted to engage the optically relevant component. For this purpose, the adjusting element 3 has a coupling region, which is preferably designed as a ball head 3a arranged concentrically to the displacement axis x.
    The housing 2 has fastening tabs 9 ', which in an assembled state (see FIG. 12) with corresponding fastening tabs 9 " connected to the servo motor 1 and are held together in a headlight housing (preferably via a Schrauverbin-training). On an upper side of the housing 2, a bevel pinion 4 is provided, which is adapted to drive the rotary member 6 in the manner described below.
    FIG. 2 shows a side view of the setting device 11, wherein it is clearly recognizable that the displacement axis x extends through an axis of symmetry of the servo motor 1 and of the rotary element 6 and the actuating element 3. As discussed in the following figures, in this advantageous embodiment of the adjustment device 11, both the servomotor 1, the actuator element 7, the transmission element 8, the rotary member 6 and the actuator 3 coaxial with the Ver thrust axis x arranged.
    Fig. 3 discloses an exploded view of the adjustment device 11, which illustrates the individual components of the adjustment device 11 and their assembly. The servo motor 1 has therein the actuator element 7, that by means of the servo motor 1 preferably linearly along the United displacement axis x can be moved Weden. The actuator element 7 is for this purpose firmly connected to a drive of the servomotor 1. The transmission element 8 is adapted to lock on a retaining ring 7a of the actuator element 7, wherein the transmission element 8 elastic means 8a in the form of individual tongues, which are arranged on the circumference of a fictitious, concentric with the Verschubachse x arranged circle and along the Verschubachse x extend. Within the elastic means 8a is provided an annular groove 8a 'shown in Fig. 4, which is defined by a fixing bevel 8a " and one of the fixing bevel 8a " opposite support surface 8a '" is limited. The transmission element 8 can be connected to the actuator element 7 by the transmission element 8 is pushed onto the actuator element 7, so that a fixing ring 7a concentrically arranged on the actuator element 7 is inserted into the transmission element 8 and thereby the fixing bevel 8a " overcomes and thus between the Fixierungsschräge 8a " and the support surface 8a '" is held. As a result, the transmission element 8 is substantially rigidly connected to the actuator element 7 with respect to displacement movements along the displacement axis x, whereas a rotational movement of the transmission element 8 with respect to the actuator element 7 about the displacement axis x is still possible. The fixing ring 7a therefore forms with the fixing bevel 8a " and the support surface 8a '" together a locking device 10 (see Fig. 4).
    The elastic means 8a of the transmission element 8 also have projections 8c, which are adapted to engage in a substantially circular to the Verschubachse x concentric opening 6a of the rotary member 6 arranged corresponding recesses 6c, wherein the projections 8c preferably in the form of paraxial pins are and the corresponding recesses 6c are designed as axially parallel grooves. In the assembled state, the transmission element 8 is accommodated in the opening 6a of the rotary element 6, wherein the projections 8c engage in the depressions 6c in such a way that a displacement of the transmission element 8 with respect to the rotary element 6 along the Verschiebachse x is possible. A rotational movement of the rotary member 6 about the Verschubachse x is transmitted via the recesses 6c by means of the projections 8c on the transmission element 8, provided that the torque transmitted thereby does not exceed a maximum limiting torque. If, for example, the maximum stroke of the actuating element 3 with respect to the transmission element 8 is reached, mechanical overloading of its connection can be prevented by deforming the elastic means 8a starting from a defined torque in such a way that the projections 8c slide out of the corresponding depressions 6c "By turning " allow the rotating member 6 with respect to the transmission element 8.
    The transmission element 8 is designed with the adjusting element 3 via a connection consisting of two connecting portions in the form of a threaded connection, wherein the transmission element 8 has a first connecting portion in the form of a threaded portion 8b and the adjusting element 3 has a corresponding second connecting portion in the form of a counter-threaded portion 3b. The counter-threaded portion 3b of the actuating element 3 is screwed onto the threaded portion 8b of the transmission element 8 in the mounted state. The maximum stroke of the actuating element 3 with respect to the transmission element 8 is on the one hand by an end face 3c of the actuating element 3 and a corresponding, arranged on the transmission element 8 and not shown in the figures contact patch on the other hand by a arranged on the transmission element 8 thread projection 8d ( see FIG. 7) as well as a threaded restriction 3d (see FIG. 6) provided in the adjusting element 3. Together, the end surface 3c, the footprint, the threaded projection 8d and the threaded constriction 3d mechanical stops, which are adapted to limit the maximum stroke of the actuating element 3 with respect to the transmission element 8 in a simple manner.
    In a region located outside the opening 6a, the rotary element 6 has a toothing 6d, in particular a ring gear, wherein the bevel pinion 4 is set up to engage in the toothing 6d. The axis of rotation of the bevel pinion 4 is so oriented to Verschubachse x that the bevel pinion 4 of a headlamp, which is installed in a vehicle, is still easily accessible. In general, the axis of rotation of the bevel pinion 4 may have any angle with respect to the Verschubachse x. Experience has shown that it is advantageous if the axis of rotation of the bevel pinion 4 occupies an angle between 80 ° and 100 ° with respect to the Verschubachse x. In a particularly preferred embodiment, the axis of rotation of the bevel pinion is oriented normal to the displacement axis x. The bevel pinion 4 is mounted in the housing 2 and sealed by means of a above the housing 2 and lying sealing ring 12, so that no liquid from an outside area on the bevel pinion 4 or its storage can penetrate into a headlight housing in which the adjustment device 11 is installed.
    4 shows a sectional view of the adjusting device 11, in which the previously discussed locking device 10 is particularly clearly visible.
    5 shows a perspective view of individual components of the adjusting device 11. Therein, a guide means 3e arranged on the adjusting element 3 is clearly recognizable, which is arranged in each case on two tongues defining a concentric opening, the tongues extending in the axial direction and at their opening side facing the counter-threaded portion 3b form. The guide means 3e are bounded by elongated recesses which also extend in the axial direction, wherein the guide elements 3e and or the depressions are adapted to engage in the housing 2 or in any other with respect to the Verschubsachse x non-rotatable region. As a result, a rotational movement of the actuating element 3 is prevented in a simple manner and allows simultaneous displacement along the Verschubachse x.
    6 and 7 show perspective views of the actuating element 3. In addition, the coupled to the control element 3 transmission element 8 is shown in Fig. 8.
    9 shows a sectional view of the adjusting element 3 accommodated in the housing 2, wherein it can clearly be seen that the guide means 3e are held in recesses which are formed in a holding section 2a of the housing 2. The holding portion 2a is formed substantially cylindrical for this purpose and arranged concentrically to the Ver-thrust axis x and has on its inside a corresponding to the guide means 3e contour.
    Fig. 10 shows a perspective partial sectional view of the adjusting device 11, in which the transmission element 8 is already clamped onto the actuator element 7 of the servomotor.
    The housing 2 is preferably formed substantially half-shell-shaped, wherein a bearing portion 6e rotary member 6 is rotatably mounted in a arranged inside the housing half-shell bearing 2e and at the same time against displacement along the Verschubachse x is secured.
    Fig. 12 shows a perspective view of the adjusting device 11, which is installed in an exemplary headlight housing 13, wherein the headlight housing 13 is only partially shown. The housing 2 is therein together with the actuator via the above-described fastening tabs 9 'and 9 ", which overlap each other in the installed state, connected by means of a screw with the headlight housing 13 and thus held stationary within the headlight housing 13. The bevel pinion 4 protrudes from the headlight housing 13 and is sealed by means of the sealing ring 12 in such a way so that water ingress into the headlight housing 13 can be prevented.
