    ADJUSTING DEVICE FOR A VEHICLE HEADLAMP
    The invention relates to an adjusting device for adjusting, for example for pivoting at least one optically relevant structural unit of a
    Motor vehicle headlight, which optically relevant unit, for example a
    Light unit or a light module is or at least a light unit or a light module comprises, and wherein the VerstelIeinrichtung comprises an actuating element, wherein the actuating element is pivotally connected to the optical unit with a first end portion, and wherein at its second end portion, the actuator coupled to a drive device is such that the adjusting element by means of the Anlriebsvorrichtung about its longitudinal axis rotatable and longitudinally displaceable along its longitudinal axis is mounted, wherein the adjusting element has a threaded portion by means of which the adjusting element is rotatably mounted in a mating thread about its longitudinal axis, wherein the mating thread with respect to a Housing of the Eahrzeugscheinwerfers is stationary, and wherein the drive device is mounted on the housing of the Eahrzeugscheinwerfers.
    Furthermore, the invention relates to a Eahrzeugscheinwerfet comprising at least one such adjustment.
    For lawful adjustment of the light image generated by a headlight, it is necessary that one or more optically relevant units of the headlight in the height direction and / or are laterally adjustable. Such an optically relevant structural unit is, for example, a light module, for example comprising light sources (n), reflector, lens, etc., but it can also be individual components such as reflectors, lenses, etc., which are adjusted accordingly. Frequently, the at least one optically relevant structural unit is mounted pivotably about one or more axes, for example about a horizontal and / or a vertical axis, in the headlight. For example, one or more oil modules are supported on a support frame, and the support frame is pivotally supported about one or two axes as described above. 2/21 -2- PI2891
    For adjustment, at least one drive device is usually provided, wherein the drive device is usually manually operable, for example, the drive device comprises a rotary knob (an adjusting screw), the rotational movement is converted by a suitable mechanism in a linear movement of a sliding element, which in corresponding slideways in the Headlamp housing is slidably guided. An adjustment point of the optically relevant assembly, e.g. the support frame, on which the assembly is mounted, is mounted in the sliding element, so that upon movement of the sliding element, the structural unit or, the support frame is pivoted.
    Since the sliding element must be suitable for being able to absorb the forces occurring during vibrations during ferry operation, the choice of material for the sliding element is limited. The attachment of the slideways to the headlight housing is technically complex. Furthermore, it is disadvantageous that by incorporating the slideways on the headlight housing and the tolerances of the housing incorporated in the overall tolerance.
    It is an object of the invention to provide an adjusting device which has a simple structure.
    Furthermore, it is an object of the invention to provide an adjustment in which the tolerances of the headlight housing can be neglected or have no influence on the tolerances of the adjustment.
    This object is achieved with an adjusting device mentioned above in that according to the invention a separate from the housing of the vehicle headlamp Führungsolomont is provided, which guide element is fixedly connected to the housing, wherein the Führungsoloment has a guide receptacle, in which guide receptacle, the at least one optically relevant assembly is mounted displaceably with a bearing area in the direction of the longitudinal axis of the actuating element, and wherein the Lagerbefeieh has a hinge portion with which the actuating element is pivotally connected to its first end region, and wherein the mating thread is fixedly connected to the Eührungsolemenl. 3/21 -3: - PI 2891
    By using a guide element, which is separated from the housing of the headlamp and formed with this connectable, the housing falls out of the tolerance chain. The guide element is connected to the housing, for example screwed, and adjusting element and bearing area of the optically relevant assembly can be optimally positioned to each other, friction forces can be kept low accordingly during the adjustment.
    It is also possible that directly in the axis of the adjustment point, i. is pressed directly in the adjustment point. On the one hand, this has the advantage that the device according to the invention can be built to save space, but on the other hand has the particular advantage that no tilting of the I.agerbereiches can occur with respect to the guide element, so that it also no jamming or a "skewer". can come.
    When using a track member, however, engages the linear actuator generated by the drive device on the track element usually not in a plane with the imaginary adjustment axis, but structurally conditioned slightly outside, resulting in the occurrence of a tilting moment on the sliding element, since this yes the force in the plane must transmit the axis. Even if it is possible to constructively position the sliding element in such a way that the force acts on the sliding element in the same plane in which the adjustment axis lies, unfavorable material pairings and, in contrast to the position of the invention, occur due to production oil lances, spring elements which are said to be so present invention relatively large contact surface undesirable forces and thus tilting moments on -es comes to a "skewering". of the sliding element.
    The design of the guide element as a separate component from the housing and the choice of materials for this component and for the housing of the headlamp is not limited, i. the material pairing between the guide element and the bearing area displaceable therein is flexibly selectable. Furthermore, the complexity of the (plastic) tools / in particular the tool for manufacturing the housing can be significantly reduced. 4/21 -4- PI2891
    In a specific embodiment of the invention it is provided that the bearing area is slidably mounted in the guide receptacle with an outer region of the joint portion.
    In addition, it is advantageously provided that the mating thread is integrally formed with the guide element.
    Characterized in that the axial movement of the adjusting element generating counter thread mounted on the guide member, preferably formed integrally therewith, the housing falls out of the tolerance chain.
    Appropriately, it is provided that the bearing region is formed as a separate from the optical assembly I agerelement which is fixedly connected to the optical assembly or fixedly connected. Usually, a connection of the bearing element is not directly to the optically relevant assembly, but the assembly is arranged in a support frame, which support frame is pivotally mounted about an axis. The bearing element is connected to this support frame, e.g. screwed. Usually, the actuator is aüS formed as a control rod.
    Furthermore, it is advantageous if the mating thread is elastic, preferably elastic at least in the direction transverse to the longitudinal axis.
    In this way, the linear force can be limited. If the occurring torque is too high, then the elastic counter thread yields.
    In a specific Äusführungsform is also provided that the first end portion is formed as a ball head, and the hinge portion of the bearing portion has a spherical receptacle, adapted to the shape of the ball head of the first end portion 5/21 -5- PI2891 I'orm, and the first Inserted end portion in the spherical receptacle, for example, is articulated in the receptacle articulated.
    In order to enable optimum sliding with low friction, it is further provided that the guide receptacle has one or more sliding surfaces, on which the bearing area, preferably the outer area of the articulated section, is slidably mounted.
    In particular, it is provided that at least two sliding surfaces, a sliding surface at an upper region in the guide receptacle and a sliding surface at a lower region in the guide receptacle are provided.
    With these sliding surfaces, a storage of the storage area and thus the optically relevant unit in z-direction, i. in the vertical direction.
    If the adjustment device is provided for setting a basic setting of the optically relevant structural unit, then it is preferably provided that the drive device can be actuated manually.
    The above-mentioned objects are further achieved with a vehicle headlamp with an adjustment device according to the invention described above / wherein the at least one optically relevant assembly is arranged in a support frame, which support frame is pivotally mounted about a pivot axis, and wherein the storage area with the support frame outside the pivot axis fix connected or formed integrally with this.
    It can be provided that two or more optically relevant structural units are arranged on the support frame, so that two or more structural units can be adjusted in a Einstellvörgang. 6/21 -6- ΙΊ2891
    In a specific embodiment, it is provided that the at least one optically relevant structural unit is designed as a lighting unit or light module. In the following the invention with reference to the drawing of an exemplary embodiment is discussed in more detail. In this shows
    1 shows a perspective section through a vehicle headlight according to the invention in the region of the adjusting device,
    2 shows a vertical section through the headlight in the region of the adjusting device,

    4 shows a support frame for a light module of the vehicle headlight.
    1 shows a detail of a vehicle headlight in the region of an adjusting device 1 for adjusting, in particular for pivoting an optically relevant structural unit of the vehicle headlight.
    In the embodiment shown, the optically relevant structural unit 100 is an illumination device, not shown, or a light module (not shown). Such a luminous unit or such a light module typically consists of an assembly comprising one or more light sources, one or more light-forming elements, such as a reflector, lens, aperture etc. In FIG. 4, this optically relevant structural unit (not shown) is designated by the reference symbol " 100 " ängedeütet.
    In principle, however, the optically relevant structural unit can 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 schwenkbär. 7/21 - 7 - ΙΊ2891
    In the following, for the sake of simplicity, (exactly) a light module is assumed to be the optically relevant structural unit.
    This light module (not illustrated) is held by a support frame 50 (see FIG. 4), which support frame 50 is mounted in the housing 200 of the headlamp, which is shown in FIG. 1, about a horizontal axis 11 and about a vertical axis V.
    The support frame is mounted pivotably about a fixed point 51 on or in relation to the housing 200 about the two axes V, H.
    With the adjustment device 1 according to the invention, a pivoting of the support frame 50 about an axis, e.g. about a horizontal axis or as shown in the present example about the vertical axis V possible (the second bearing point through which the vertical axis V extends and which is not a fixed point in the cone, is not shown in the figures).
    As can be seen in particular Figures 1 - 3, the adjusting device comprises an actuating element 2, which is preferably designed as an actuating rod, wherein the actuating element 2 with a first end region 2b articulated with the optical assembly 100, i. is connected to the support frame 50.
    At its second end region 2 c, the slat element 2 is coupled to a drive device 3 in such a way that the slat element 2 can be rotated about its longitudinal axis 2 a by means of the application device 3.
    The drive device 3, which is mounted on the housing 200, is manually operable and comprises an adjusting screw 3a, the rotational movement is reacted in a known manner in a rotary movement of the rotary part 3b. The rotary member 3b has an elongated receptacle 3b ', in which the adjusting element 2 is inserted with its portion 2c. Due to the cross-sectional configuration of the receptacle 3b 'and the corresponding adapted thereto section 2c of the actuating element 2, this can be moved in its longitudinal direction 8/21 -8- PI2891, upon a rotational movement of the rotary member 3b, the actuating element 2 is rotated with this.
    The adjusting element 2 has a threaded section 2d, by means of which the adjusting element 2 is mounted in a counter thread 4a about its longitudinal axis 2a, whereby the counter thread 4a is arranged stationary with respect to the housing 200 of the vehicle headlight.
    Furthermore, a separately formed from the housing 200 of the vehicle headlight guide member 4 is provided, which is fixedly connected to the housing 200 and is screwed, for example by means of screws 40 to the housing 200.
    The guide element 4 has a guide receptacle 4b, in which the light module 100 or the support frame 50 with its bearing region 5 is displaceably mounted in the direction of the longitudinal axis 2a of the actuating element 2.
    The storage area 5 is formed as a separate from the light module and from the support frame 50 bearing element 5, which is fixedly connected to the light module 100, specifically connected to the support frame 50 or fixed and can be screwed to the support frame 50, for example.
    The bearing element 5 has a hinge portion 5a, with which the actuator 2 is pivotally connected to its first end portion 2b, also the GegengeWinde 4a is firmly connected to the Führungsseiement 4, preferably configured integrally with the guide element 4.
    The bearing element 5 is slidably mounted with an outer region 5a 'of the joint portion 5a in the guide receptacle 4b, wherein preferably the Ftihrtmgsaufeahme 4b sliding surfaces 4b', on which the outer region 5a 'of the hinge portion 5a of the bearing element 5 is slidably mounted. In this case, at least two sliding surfaces 4b ', a sliding surface at an upper region in the guide receptacle 4b and a sliding surface 4b' at 9/21 -9- PI2891 a lower region in the guide receptacle 4b, are provided. With these sliding surfaces, a storage of the storage area and thus the optically relevant unit in the z-direction, i. in the vertical direction.
    Upon rotation of the actuating element 2 by means of the drive device 3 generate thread 2d and mating thread 4a axial displacement of the actuating element 2 in Ric tion of its axis 2a, whereby the I ragrahmen 50 is moved accordingly and thus pivoted about the vertical axis V.
    Furthermore, it is advantageous if the counter thread 4a is elastically ausgebildel. Preferably, at least or exclusively in the direction transverse to the longitudinal axis 2a is formed elastically. In this way, the linear force can be limited. If the occurring torque is too high, the elastic counter thread 4a yields. For this purpose, e.g. a bracket 8 (see Figure 3) provided by which determines the maximum torque and the adjusting rod 2 is held in the mating thread 4a.
    With the clamp 8, the counter thread 4a is pressed in the direction of the longitudinal axis 2a on the thread 2d of the actuating element 2. When a certain torque is exceeded, the counter thread 4a is pressed apart against the force of the clip 8, so that the adjusting element rotates without moving in the longitudinal direction.
    The first end portion 2b of the control element 2 is formed as a ball head, and the hinge portion 5a of the Lagerbefeiches 5 has a spherical receptacle 5a "on which a form adapted to the shape of the ball head of the first end portion 2b forms. The first Ehdbereich 2b is inserted into the spherical receptacle 5a ", for example, in the receptacle 5a" is hingedly engaged.
    With the invention, there are a number of advantages: • after no sliding element which is displaceable in the housing, it can no longer tilt; 10/21 -10- ΙΊ2891 • the force of the control element can directly engage in the pivot axis through the adjustment point; • The entire weight of the support frame including the at least one optically relevant assembly is received in the guide member and no longer in a sliding element and slideways on the housing; • The track surfaces of the guide element can be tuned easier tool technically, since the tool is small and simple and no longer in the
    Housing tool is integrated; • The housing tool can be made simpler, since no slideways in the housing are more necessary and only two receiving points must be provided for the guide member; • The material for the guide element and for the guideways can be selected independently of the housing material, so that better sliding properties can be achieved; • The fact that not only the support elements but also the rod are mounted on the axial movement generating threaded portion in the Führungselemenl, a more precise alignment of these two components to each other is possible because the housing falls out of the Toleronzkette This is particularly advantageous because housing naturally more susceptible to distortion due to their complexity, more demanding to reconcile with other components, and any changes made more complex and expensive; • There is no bending stress on the actuator, as it is not stored in the housing. 11/21
