    Gleitbahnlager
    The invention relates to an adjusting device for adjusting - for example, for pivoting - of at least one optically relevant structural unit of a motor vehicle headlamp within the housing of the headlamp, wherein the adjusting device comprises an actuating element, a bearing component and a sliding element, wherein the adjusting element is rotatably mounted in the bearing component , cooperates with a mating thread of the sliding member, and wherein the sliding member is pivotally connected to the optical unit at a connecting portion.
    Adjustment devices of this type are well known and serve to adjust the position and / or orientation of optical components of headlamps; For example, the optically relevant structural unit is a lighting unit or a light module or at least comprise a light unit or a light module. They are characterized by simplicity of adjustment, but they are difficult to install because in particular the attachment points are difficult to access the housing, which increases the susceptibility to errors during the assembly process.
    It is therefore an object of the invention to provide an adjusting device which allows easier and faster installation in a housing of a motor vehicle headlight.
    This object is achieved on the basis of an adjusting device of the type mentioned above in that according to the invention the bearing component is formed as a separate component from the housing and fixedly mounted on the housing, i; iwobei the actuator is rotatably mounted in a holding region of the bearing component about its longitudinal axis and the actuator having a drive portion geared to a drive means and a threaded shaft portion cooperating with a mating thread of the slider, the slider having a connection area to which it is hingedly connected to the optical unit, and also (from Housing separate) bearing component comprises a guide portion in which the sliding element is mounted parallel to the longitudinal axis of the actuating element displaceable.
    This solution provides a slide bearing in the form of the bearing component described above, on the one hand provides a guide for the sliding member and on the other hand supports and positions the actuator in the housing. This allows for simplification in the assembly of the adjustment and improved adjustment options, with a small number of individual components, and consequently lower costs of manufacturing, assembly and reworking such as adjustment and tuning loops, and faster and easier validation. In addition, the adjusting device according to the invention is suitable for use for several types of headlights or housings.
    In a particularly advantageous embodiment of the invention, the adjusting element is arranged outside the Fübrungsbereiches; In this case, the sliding element may be designed so that only at least one guide part of the sliding element is held displaceably in the guide region.
    In addition, it is favorable and reduces the number of components when the holding portion and the guide portion of the bearing component are formed integrally with each other.
    Advantageously, the drive section may be formed at one end of the adjusting element, which is preferably designed as an adjusting screw, for example.
    According to another aspect of the invention, the drive portion may comprise a bevel gear, wherein the drive means is formed as an adjusting shaft with a bevel pinion, which cooperates with the bevel gear, and a led out of the housing headboard. Here, the head part of the adjusting shaft has a shoulder for an external tool, wherein the approach is preferably designed as a depth stop for an external tool and projects centrally along the longitudinal axis of the setting shaft in the head part.
    It is also a particular advantage of the invention that the adjusting device and in particular the adjusting element lies wholly within the housing. This reduces the risk of contamination and damage. For corresponding reasons, it is advantageous if the drive device is mounted in the housing, for example rotatable in an opening in the housing, wherein the holding portion preferably has a (located inside the housing) latching device, on which the drive means in its operating position with respect to the actuating element latched has.
    According to a further aspect of the invention, the fastening of the adjusting device takes place exclusively via the bearing component, which is fastened by means provided in the holding area openings by means of fastening bolts or screws to the housing.
    The invention together with further details and advantages will be explained in more detail below with reference to a non-limiting embodiment shown in the accompanying drawings. The drawings show:
    1 shows an adjusting device for a motor vehicle headlight according to the embodiment form in a perspective view.
    Fig. 2 is another perspective view of the adjusting device;
    Fig. 3 is a sectional view of the holding portion and the drive means of the adjustment device;
    4a and 4b, the bearing shell of the adjusting device in a view on the outside and from the inside; and
    Fig. 5 shows the adjusting device in the housing mounted position.
    In the description given here, terms such as "right", "left", "top" and "bottom" refer to a position of the adjusting device according to the invention, when viewed in the direction along the longitudinal axis of the adjusting element (in particular the adjusting screw), said End, which cooperates with the adjusting shaft (in particular the drive pinion), facing the viewer and the adjusting shaft is oriented upwards; However, these terms are only conventional and independent of the actual installation position, which may possibly be completely different. In this sense, Fig. 1 shows a view of the right side of the adjusting obliquely from above and Fig. 2 is a view of the left side.
    Referring to FIGS. 1 and 2, the adjusting device 1 according to the first exemplary embodiment comprises an adjusting element in the form of an adjusting screw 2, which is set up to adjust the position of a sliding element 4 of the adjusting device 1 displaceably mounted in a bearing shell 3. The bearing shell 3 represents the bearing component of the invention; it is inserted into the housing 5 of the headlamp (Figure 3) and fixedly mounted therein.
    The adjusting screw 2 has at one end a head 20 with a bevel gear 21, and a shaft 22 with an external thread 24. It is rotatably mounted about its longitudinal axis c in a holding portion 32 of the bearing shell 3, for example in a head 20 with the shaft 22 connecting neck portion 23. The head 20 and the neck portion 23 together form a drive portion 25 of the adjusting screw 2; the drive section 25 is geared together with an adjustment shaft in the form of a drive pinion 6 through which the adjusting screw 2 can be actuated. In Fig. 3, the drive pinion 6 can be seen in its installed position in the housing 5; Fig. 3 is a sectional view taken along a sectional plane passing through the longitudinal axes b, c of the drive pinion 6 and the adjusting screw 2. The drive pinion 6 has at its inwardly directed end a bevel pinion (bevel gear) 61, which cooperates with the bevel gear 21 of the adjusting screw and thus actuates the adjusting screw. The drive pinion 6 is inserted in an opening 50 of the housing and has a led out of the housing 5 head portion 60. It is rotatably mounted in this opening 50 and can also be sealed by an Ö-ring 51 to the interior of the housing 5, in a shaft portion of the drive pinion 6, for example, just above the bevel 61, a groove 62 may be provided, as below described for holding the bevel pinion 6 in its position with respect to the bearing shell 3 is used. The bevel pinion 61 is thus located within the housing, as well as the actuator 2 is preferably located entirely within the housing 5.
    For example, the head portion 60 may be configured to incorporate therein an external tool, such as an external tool. a hex tool can be used; For this purpose, the head part may for example have a projection 63 in the form of a depth stop for the external tool, which projects centrally along the longitudinal axis b of the setting shaft 6 in the head part 60. In a variant, the head part can be designed to be connectable with a motor drive, directly or geared , eg connected to a drive axle of an electric motor.
    Referring again to Figs. 1 and 2, the bearing shell 3 comprises a holding portion 32 which is designed as described for the bearing of the adjusting screw 2, and (at least) a guide portion 34 in which the sliding member 4 in a direction parallel to the longitudinal axis c of the actuating element is slidably mounted. Preferably, the holding portion 32 is integrally formed with the (or each) guide portion 34; in general, it is advantageous if the entire bearing shell 3 is formed in one piece.
    The sliding element 4 has a threaded portion 42 which cooperates as a mating thread with the thread 22 of the adjusting screw, so that a rotation of the adjusting screw is converted into a longitudinal movement of the sliding element along the longitudinal axis c. In the illustrated embodiment, the threaded portion 42 includes an open internal thread, wherein the adjusting screw 2 is held by a retaining clip 40 in the engaged position of the (external) thread 22 with the threaded portion 42. The sliding element 4 also has an articulated connection 41 with an optical unit 10, whereby the longitudinal movement of the sliding element 4 is converted via the articulated connection 41 into an adjusting movement of the assembly 10.
    The sliding element 4 has at least one guide part 43, which is arranged projecting from the threaded region, for example below and / or above. In the embodiment shown, two guide parts 43, 43 a are provided, respectively at the bottom and at the top of the sliding element. Each of these guide parts is held in a corresponding part of the guide region 34 of the bearing shell 3. In this case, it is advantageous that the guide region of the bearing shell 3 does not surround the actuating element 2, this is thus arranged outside the guide region 34, so that only the guide parts 43, 43a are held displaceably in the guide region 34 (or in a respective corresponding guide region). It may also be provided only a guide part, or possibly more than two guide parts of the sliding element.
    FIGS. 4a and 4b show the bearing shell 3 (which represents a separate component from the housing 5) in a view along or counter to the axis c. Fig. 4a shows the outwardly directed side of the bearing shell, more precisely of the holding portion 32; This page serves as an interface for attachment to the housing 5. For this purpose, recesses 31 and mounting holes 38 are provided in the holding portion 32. In the holding portion 32 also the opening 30 can be seen, through which the adjusting screw 2 is inserted and rotatably supported.
    As can be seen in Figures 3 and 4a, the guide portion 32 may advantageously comprise an open-sleeve portion 33 which defines a portion of the drive pinion 6, here e.g. of bevel pinion 61, partially surrounds. The region 33 favorably has a projection 36, e.g. in the form of a nose or ring-like partially circumferential bar; this serves as a latching device, which can engage in the above-mentioned groove 62. By this latching lock the drive pinion in a defined operating position with respect to the
    Bearing shell and in particular the bevel gear 21 of the adjusting screw 2 is held. In a variant, instead of the groove, a ring-shaped or ring-sector-like projection may be provided, which engages in a corresponding recess of the guide region.
    It can also be seen in FIGS. 3 and 4b that the opening 30 forms a stop 37 towards the outside, e.g. in the form of one or more strips, whereby a stop for the neck portion 23 of the adjusting screw 2 is formed. As a result, their movement is limited forward along the longitudinal axis c; in the opposite direction of the head 20 is abut stop webs 52 in the housing 5, so that the movement is also limited backwards. The housing 5 also surrounds the head 20 at least partially along the circumference and thus forms an additional guide of the adjusting screw 2 outside of the actual assembly 11 of the adjusting device according to the invention. If desired, a weakened or perforated portion (not shown) may be provided about the aperture 30 and the stop edge 37, permitting resilient yielding of the stop edge 37 to allow tolerance for balancing against the housing.
    The bearing shell 3 thus forms a Gleitbahnlager, which on the one hand represents the guide for the sliding member 4 and on the other hand, the adjusting screw 2 positioned with respect to the housing 5 and / or the bevel pinion 61 of the drive shaft. With the adjusting screw and the sliding element, the bearing shell forms an assembly 11 (FIG. 2) which can be preassembled - even without the drive pinion 6 - and inserted as a whole into a housing 5 of a headlight.
    To mount the assembly 11, the slider 4 is first inserted into the guide portion 34, then the adjusting screw 2 is guided with the shaft 22 ahead through the opening 30 and inserted into the internal thread 42 of the slider 4 and the retaining clip 40 is applied; In this way, the adjusting screw 2 is locked in its rotatable about its longitudinal axis c working position.
    Then, the assembly 11 is used, wherein the recesses 31 are set in the holding portion 32 on corresponding projections or pins (not shown) in the housing 5 of the headlamp and thus they cause a correct positioning. The positional relationship between the housing 5 and the assembly 11 takes place exclusively via the in
    Fig. 4a shows an outwardly (i.e., to the housing) facing surface of the bearing shell 3, preferably via a positive connection allowing the least possible tolerance.
    After inserting this assembly in the housing, the drive pinion 6 is used. Here, if necessary, the assembly 11 in the direction corresponding to the longitudinal axis c, are slightly moved and / or the adjusting screw 2 are temporarily moved out of the opening 30 to allow the insertion of the drive pinion 6 to its end position. Finally, by the latching device formed by the projection 36 of the guide portion 32 and the groove 62 of the drive pinion 6, a well-defined positional relationship of the assembly to the housing 5 and the drive pinion 6 is achieved, including making the geared connection between the set screw 2 and the drive pinion 6 After inserting the drive pinion 6, finally, the bearing shell 3 as in Eig. 5 can be fixed in the housing 5, for example using the mounting holes 38 by means of fastening screws 35 or other suitable fastening means. Here are, as in Eig. 5 recognizable, the mounting holes 38 at easily accessible locations in the housing. 5
    As can be seen from the above, the invention allows simplifications in the installation of the adjustment and improved adjustment options, with a small number of the individual components. This results in lower manufacturing, assembly, and rework costs such as adjustment and tuning loops, as well as faster and easier validation. In addition, this module can be used in the same design for several types of headlights or housing types.
    If desired, the bearing shell or the bearing component can also assume additional functions in the sense of the invention, such as e.g. as attachment for other components of the headlamp.
    The invention provides as a further advantage that it allows all the gear-like couplings (in particular the toothing bevel pinion adjusting screw and the threaded connection between the adjusting screw and sliding element) are located within the housing. The length of the Einstellritzels can be varied in the housing tool in a simple manner.
    It will be understood that the embodiments disclosed herein are presented for illustration of the invention only and are not to be construed as limiting the invention. The skilled person can make many modifications and designs for this purpose. Thus, the adjusting device according to the invention can also be used for setting other optically relevant components of a headlight.
