    vehicle headlights
    The invention relates to a vehicle headlight with a housing and with at least two optically relevant units, for example at least two light modules and / or light module units, wherein each of the at least two optically relevant units are pivotable about a horizontal axis and about a vertical axis.
    In a vehicle headlight, it is necessary or required by law that the light beam generated by the headlight in the vertical and / or horizontal direction can be adjusted (default). If the vehicle headlamp comprises one or more light modules or light module units, it is usually provided that these light modules or relevant components of these light modules, which influence the orientation of the emitted light beam, e.g. a lens, a reflector, etc. are set accordingly. Typically, the setting of the light modules, the light module units (a light module unit is made of one or more light modules that form a unit in that they are adjusted together, for example, sit rigidly on a common carrier or otherwise fixed to each other ) or their components (in the following only the setting of the light modules is mentioned, but it is clear that they can also mean only components of the light modules) by pivoting about axes, typically around horizontal and / or vertical axes.
    If the vehicle headlight comprises two or more light modules, then it is generally favorable if these light modules are seated on a common support frame, which common support frame can be pivoted with corresponding adjustment devices about a horizontal and / or about a vertical axis. In this way, two or more light modules can be set in one direction with a single adjustment, or with two adjusters all light modules can be adjusted in the vertical and horizontal directions.
    However, modern vehicle design often requires a large "sweep". the light modules in a vehicle headlight. "Sweep " means that - usually the one or more outer light modules of a headlamp are opposite to the inner Lichtmo- 2/35 -2- PI2893 dulen offset from the direction of travel to the rear. The angle between a vertical plane passing through two light modules of a headlamp and a vertical plane normal to the direction of travel is called a sweep angle. In current vehicles, the sweep angle is already partially 45 °.
    With increasing sweep angle, it becomes more difficult or sometimes impossible to arrange two or more light modules (eg, a low beam and a high beam light module) on a common support frame because of the large deflections of the light modules due to the sweep and the large distance to the pivot point would come.
    Accordingly, it is necessary in the prior art to make each light module (or each Lichtmo-dul unit) separately adjustable, for example by each light module is disposed on a separate support frame, which is pivotable about a horizontal and / or vertical axis is. Accordingly, a separate adjustment is required for each light module and for each pivot axis.
    It is an object of the invention to provide a vehicle headlight in which it is possible to set two or more optically relevant building units, such as light modules or light module units, together with only one adjustment device per adjustment direction.
    This object is achieved with a vehicle headlamp mentioned above in that according to the invention at least two of the optically relevant assembly are each arranged in a support element, which support elements are mounted in the housing about a respective horizontal axis and about a vertical axis pivotally, and wherein for pivoting the support elements a horizontal axis pivoting device is provided about the horizontal axes, which horizontal axis pivoting device pivots a support element about its horizontal axis, and wherein the at least two support elements are coupled to a horizontal axis coupling device such that upon pivoting of the support element with the horizontal axis pivoting device and the at least one further support element is pivoted about its horizontal axis, and wherein for pivoting the two support elements vorges about their at least one vertical axis a vertical axis pivoting device is marriage, which vertical axis Verschwenk pivots a support member about its vertical axis, and wherein the at least two support members are coupled to a vertical axis coupling device such that upon pivoting of the support member with the vertical axis Ver pivoting device also the at least one further support element is pivoted about its horizontal axis.
    According to the invention, only one pivoting device is thus provided per pivot axis, with which a support element, on which an optically relevant structural unit is arranged, is pivoted. By appropriate coupling with another support element for a further optically relevant structural unit, this further support element is mitverschwenkt accordingly and thus also set the other unit with the appropriate pivoting device. By separating into two separate support elements and corresponding coupling, the arrangement can be made such that even with a large sweep of optically relevant units whose deflection takes place at a desired setting and not too large deflection as in the prior art when using a common Support frame takes place.

    Fig. 6 is a perspective view of the pivoting mechanism of the vehicle headlight of Figure 4 in a view obliquely from behind.
    Figures 1, la, 2 and 3 show a section of a vehicle headlight 1, which has a housing 10, and has two optically relevant units 2, 3, which are arranged in the housing 10.
    An optically relevant structural unit is, for example, a light module, a light module unit, which consists of one or more light modules, or one or more components of such a light module or such a light module unit, wherein this component or these components Have an influence on the light distribution generated by the light module or by the light module unit.
    With a light module, a specific light distribution, such as a high beam distribution, a dimmed light distribution, such as a dipped beam, a fog light distribution, etc. can be generated, or a light module is used in the context of a light module unit for generating a part of such a light distribution.
    In the case of 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 the light distribution generated by the light module unit, it can be, for example, a reflector, a lens, a diaphragm, a light source or a light source a light source arrangement or other light-shaping means, such as optical fibers, light guide, etc. act.
    The position of the optically relevant structural units, which are not shown even in the figures, also in Figure 1, is indicated by the reference numerals 2 and 3. The two optically relevant units 2, 3 are each pivotable about a horizontal axis H2, H3 and about a vertical axis V2, V3. About these axes, the units 2, 3 can be pivoted to adjust their default. It may also be possible that the units are pivoted about these axes further for headlamp leveling and / or for the realization of a cornering light function 9/35 -9- PI2893. In principle, however, it is also possible for the curved light axes to lie at a different location than the vertical axes V2, V3.
    For pivoting, each of the optically relevant structural units 2, 3 is arranged on a support element 20, 30, wherein these support elements 20, 30 are mounted in the housing 10 about a respective horizontal axis H2, H3 and about a vertical axis V2, V3 pivotally.
    In the example shown, the support element 20 for the first structural unit 2 is a support frame, while the support element 30 for the second structural unit 3 in this example is a support plate.
    In principle, of course, it can also be provided that the support element is formed integrally with the light module or a light module unit.
    The first support element 20 is mounted with three bearing points 20a, 20b, 20c in the housing 10, wherein a first and a second bearing point 20a, 20b, the horizontal axis H2 and the second and a third bearing point 20b, 20c form the vertical axis V2.

Via the fixed bearing point 20b, through which the horizontal axis H2 and the vertical axis V2 extend and intersect there, the first support element 20 is articulated to the housing 10 or articulated to a fixed component with respect to the housing. The fixed bearing point 20b is thus not displaceable with respect to the housing 10, but pivoting movements of the support element about this fixed bearing point 20b are possible.
    In addition, the second support member 30 is mounted with three bearing points 30a, 30b, 30c in the housing 10, wherein a first and a second bearing point 30a, 30b, the horizontal axis H3 and the second and a third bearing point 30b, 30c form the vertical axis V3.
    The second bearing point 30b of the second support member 30 is a fixed bearing point which is fixed with respect to the housing 10. The fixation bearing point 30b, through which the horizontal axis H3 and the vertical axis V3 extend and intersect, the second support element 30 is articulated to the housing 10 or to a stationary component with respect to the housing articulated. The fixed bearing point 30b is thus not displaceable with respect to the housing 10, but pivoting movements of the second support element 30 about this fixed bearing point 30b are possible.
    In the embodiment shown is further provided that the two fixed bearing points 20b, 30b of the support frame 20, 30 are arranged one behind the other, wherein preferably the first support frame 20 is disposed behind the second support frame 30. The term "behind" means that the first support frame is arranged opposite to the direction of travel / light exit direction with respect to the second support frame.
    For common pivoting of the support elements 20, 30 about their horizontal axes H2, H3, a horizontal axis pivoting device 41 is provided, which is better seen in particular in Figures 2 and 3. With this horizontal axis tilting device 41, the first support element 20 can be pivoted about its horizontal axis H2 when actuated.
    The adjusting device 41 consists in a known manner, for example, a manually operated rotary 41a, the rotation is converted into a linear movement of an actuating element 41b. This adjusting element acts on the first support element 20 and leads to a pivoting movement of this support element about the horizontal axis H2. In the example shown, a drive 90, preferably an electric drive for headlamp leveling is additionally arranged in the travel of the control element 41b, which is shifted in the adjustment of the default setting and then in the operation of the headlamp, the beam range of the generated light distribution (s) by pivoting the horizontal axis, preferably dynamic, regulated.
    Furthermore, the two support elements 20, 30 are coupled to a horizontal axis coupling device 60 such that upon pivoting of the first support member 20 with the horizontal axis pivoting device 41 and the second support member 30 is pivoted about its horizontal axis H3. 11/35 -11- PI2893

    Furthermore, the two support members 20, 30 are coupled to a vertical axis coupling device 70 such that upon pivoting of the first support member 20 with the vertical axis Ver pivoting 51 and the second support member 30 is pivoted about its horizontal axis V3.
    In particular, it is provided in the first variant of the invention, as shown in Figures 1-3, that the horizontal axis pivoting device 41 - preferably directly or, as shown, via interposition of a LWR drive 90 - engages the first support member 20 to which the horizontal axis pivoting device 41 in the first bearing point 20c is pivotally connected to the first support member 20.
    In addition, it is provided that the vertical axis pivoting device 51, preferably directly, also acts on the first support element 20, wherein it is provided that the vertical axis pivoting device 51 is pivotally connected to the first support element 20 in the first bearing point 20a.
    Furthermore, it is provided that the horizontal axis coupling device 60 in the region of the third bearing point 20c is pivotally connected to the first support member 20. In this case, the horizontal axis coupling device 60 in the third bearing point 30c of the second support member 30 is pivotally connected to the second support member 30. 12/35 -12- PI2893
    Furthermore, the vertical axis coupling device 70 connects the two support frames 20, 30 directly to each other, for which purpose the vertical axis coupling device 70 is pivotally connected to the second support element 30 in the first bearing point 30a of the second support element 30. The vertical axis coupling device 70 is connected to the first support member 20 in a hinge point 70a, which lies on the horizontal axis H2 between the first and the second bearing point 20a, 20b of the first support member 20a, articulated. In this way, a pivoting of the two support elements can be realized to the same extent (so that the support elements are adjusted to the same extent, it is preferably provided that the distances 20a to 20b and 30a to 30b and 20b to 20c and 30b to 30c be the same). For example, it is provided that the hinge point 70a lies in the middle between the first and the second bearing point 20a, 20b on the first support frame 20.
    All articulated connections are advantageously designed as ball joints, so that a rotation of the moving parts can be realized by 2 axes.
    In the structurally simple and cost-effective embodiment it can be provided that the horizontal axis and the vertical axis coupling device 60, 70 are each formed as a single coupling element, preferably as a coupling rod 60, 70.

    It may also be provided that the vertical axis coupling device 70 is configured analogously to the alignment about or a vertical axis as described above, in which case the coupling rod element is rotated in the bearing point 70a, so that adjustment from the rear side is possible.

    FIGS. 4-6 describe a second embodiment of a vehicle headlight 1 according to the invention, wherein, in contrast to FIG. 1 in FIG. 4, the housing 10 is not shown, although it is present in the same way.
    The basic relationships are also in this embodiment the same as in the first variant of Figures 1-3, in the following therefore, the differences of the second to the first variant are mainly to be shown.
    The figures, in particular Figure 4 show a section of a vehicle headlight 1, which has a housing 10, and has two optically relevant units 2, 3, which are arranged in the housing.
    An optically relevant structural unit is in turn, for example, a light module, a light module unit which consists of one or more light modules, or one or more components of such a light module or such a light module unit, this component or these components have an influence on the light distribution generated by the light module or by the light module unit.
    With a light module, a specific light distribution, such as a high beam distribution, a dimmed light distribution, such as a dipped beam, a fog light distribution, etc., or a light module is used in the context of a light module unit to produce a part of a such light distribution.
    In the case of 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 the light distribution generated by the light module unit, it can be, for example, a reflector, a lens, a diaphragm, a light source or a light source a light source arrangement or other light-shaping means, such as optical fibers, light guide, etc. act.
    The position of the optically relevant structural units, which are not shown even in the figures, also in Figure 1, is indicated by the reference numerals 2 and 3. The two optically relevant units 2, 3 are each pivotable about a horizontal axis H2, H3 and about a vertical axis V2, V3. About these axes, the units 2, 3 can be pivoted to adjust their default. It may also be possible that the units are further pivoted about these axes for headlamp leveling and / or to realize a cornering light function.
    For pivoting, each of the optically relevant structural units 2, 3 is arranged on a support element 20, 30, wherein these support elements 20, 30 are mounted in the housing about a respective horizontal axis H2, H3 and about a respective vertical axis V2, V3.
    The support elements 20 for the first structural unit 2 and the support element 30 for the second structural unit 3 are each a support frame in the example shown.
    In principle, of course, it can also be provided that the support element is formed integrally with the light module or a light module unit.
    The first support element 20 is mounted with three bearing points 20a, 20b, 20c in the housing, wherein a first and a second bearing point 20a, 20b, the horizontal axis H2 and the second and a third bearing point 20b, 20c form the vertical axis V2.

About the fixed bearing point 20b, through which the horizontal axis H2 and the vertical axis V2 extend and intersect there, the first support member 20 is articulated to the housing or on the plate 80 articulated. The fixed bearing point 20b is thus not displaceable with respect to the housing, but pivoting movements of the support element 20 about this fixed bearing point 20b are possible.
    In addition, the second support member 30 is mounted with three bearing points 30a, 30b, 30c in the housing 10, wherein a first and a second bearing point 30a, 30b, the horizontal axis H3 and the second and a third bearing point 30b, 30c form the vertical axis V3.
    The second bearing point 30b of the second support member 30 is a fixed bearing point which is fixed with respect to the housing 10. The fixed bearing point 30b is also disposed on plate 80. About the fixed bearing point 30b, through which the horizontal axis H3 and the vertical axis V3 extend and intersect there, the second support member 30 is hinged to the housing or on the plate 80 articulated. The fixed bearing point 30b is thus not displaceable with respect to the housing, but pivoting movements of the second support element 30 about this fixed bearing point 30b are possible.
    For common pivoting of the support elements 20, 30 about their horizontal axes H2, H3, a horizontal axis pivoting device 41 is provided. The adjusting device 41 consists in a known manner, for example, a manually operated rotary member 41a, the rotation is converted into a linear movement of an actuating element 41b. This adjusting element acts on the first support element 20 and leads to a pivoting movement of this support element about the horizontal axis H2. In the example shown, a drive 90, preferably an electric drive for headlamp leveling is additionally arranged in the travel of the actuating element 41b, which is also moved in the setting of the default setting and then in the operation of the 16/35 -16- PI2893
    Headlamps, the luminous range of the generated light distribution (s) by pivoting about the horizontal axis, preferably dynamically, regulated.
    Furthermore, the two support elements 20, 30 are coupled to a horizontal axis coupling device 60 such that upon pivoting of the first support member 20 with the horizontal axis pivoting device 41 and the second support member 30 is pivoted about its horizontal axis H3.
    It is provided that the horizontal axis coupling device 60 is pivotally connected to the first support member 20 via the third bearing point 20c and hinged to the second support member 30 via the third bearing point 30c. In addition, the horizontal axis adjustment device 41 is pivotally connected to the horizontal axis coupling device 60 in a hinge point 41c, so that when adjusting the horizontal axis coupling device 60 by means of the horizontal axis adjustment 41, the two support members 20, 30 pivoted about their horizontal axes H2, H3 become.
    For pivoting the two support elements 20, 30 about their vertical axes V2, V3, a vertical axis Ver pivoting device 51 is provided. Usually, this is a United pivoting device 51, which has a similar structure as the Ver-pivoting device 41.
