    Externally locking adjusting shaft for adjusting a vehicle headlight
    The invention relates to an adjustment shaft, via which in an automotive headlamp an adjustable component of the headlamp, in particular a reflector or other light module, is adjustable via an inner control shaft, with a head part and a shaft adjoining the head part, the one about a longitudinal axis substantially has rotational symmetrical basic shape, as well as with a pinion, which cooperates in the assembled state with a gear rim of the inner actuating shaft.
    Moreover, the invention relates to an adjustment mechanism in a vehicle headlight for adjusting an adjustable component of the headlamp, with an adjusting shaft of the type mentioned
    An adjusting shaft of this type is disclosed, for example, in DE 4141150 A1, wherein it is called an input shaft. This input shaft is rotatably supported in a tubular body so that an outer part is accessible, while inside a pinion of the input shaft engages in a pinion of an output shaft and so on Rotary movement for adjusting the headlight transmits. The input shaft is held by means of located on the inside of the tubular body rib or groove in the manner of a snap fit. In addition, a pushed onto the tube body collar for holding the input shaft is provided. For sealing an O-ring is provided, which is housed in a circumferential groove of the input shaft. An element similar to this input shaft is described in DE 196 05 758 A1, which, however, has no collar. The structure of these conventional adjusting elements is complicated because it comprises several complicated-shaped components whose manufacture also requires a variety of moldings.
    Another adjusting shaft is described in EP 0 615 880 Al as an adjusting knob, which is inserted into a pivot pin, wherein the pivot pin terminates in a gear which rotates a second actuating shaft. This device is complex because a large number of components must be joined together. In addition, the knob is mounted on an O-ring with sealing effect in the axial direction, which is why forces that are inevitably exerted on the knob during a setting operation, must be absorbed by the O-ring. This brings a high load of the O-ring with it. An adjusting wheel similar to this adjusting knob is shown in DE 4013 893 A1.

    It is therefore an object of the invention to provide an externally accessible adjustment shaft with a
    Shaping to create a reliable, yet easy to produce locking in the hollow of the setting allows also the production of the
    Adjusting shaft with the smallest possible number of tools (especially form- »
    Tools for injection molding) may be possible.
    This object is achieved on the basis of an adjusting shaft of the type mentioned above in that the head part of the adjusting shaft has at least one detent hook projecting outwardly from the longitudinal axis with at least one latching means located thereon and oriented towards the shaft.
    This solution according to the invention results in a simplified production of the component of the setting shaft. The outwardly latched locking allows a simpler design of both the setting shaft itself and the corresponding with this housing part in which the adjusting shaft is mounted.
    In an advantageous development of the invention, the latching hook has an offset opening, through which the latching means, seen in the viewing direction parallel to the longitudinal axis on the head part, is exposed. This measure allows in the preparation of the adjusting shaft by injection molding a demoulding of the setting of the mold without additional moldings or a slider would be required.
    Moreover, it is favorable if the head part has a number of locking hooks with locking means, e.g. two, four, five, six, seven or more. These can be arranged uniformly around the circumference of the head part.
    The head part of the adjusting shaft according to the invention can be formed in one piece with the shaft and the pinion in a favorable manner; In addition, the shaft may have a portion away in the direction of the head portion and / or gradually decreasing diameter. This development results in a simplified production of the component of the setting shaft. In particular, due to the diameter decreasing towards the end of the stem, it is now possible to form the stem in a single forming part of the casting mold. This avoids the occurrence of separation markings on the shank caused by gaps in the casting mold, which are noticeable as a ridge. F12474 ft ftft. Ft ftft. t • ft ·· * ·· ft * ·· * · «-3-. In addition, the seal is improved by the O-ring, and the O-ring is much less useful; In addition, damage to the O-ring during installation of the adjusting shaft is avoided.
    In order to ensure reliable positioning of a sealing ring serving as O-ring, it is advantageous if the shaft has a circumferential shoulder, which is followed by a preferably cylindrical portion for receiving a sealing ring.
    In a particularly favorable design, the pinion is arranged at one end of the shaft, namely that opposite the head part. Here, the pinion can connect to a conical portion of the shaft, wherein the outer radius of the pinion extends within the extension of the conical portion.
    The head part as outside of the housing lying part of the adjustment shaft may be provided with an approach for an external tool. Preferably, the approach is designed as a depth stop for an external tool, wherein it can protrude centrally along the longitudinal axis in the head part.
    As already mentioned, the shank can have a circumferential shoulder, and additionally on both sides of the shoulder a conical section which serves for the centering guidance of the setting shaft. This improves the stability of the alignment of the component in his leadership. In this case, between the shoulder and at least one of the conical sections, an intermediate region may be formed with a diameter offset from the conical section in order to achieve an exemption.
    The adjusting shaft according to the invention is suitable for an adjustment mechanism in a vehicle headlight for adjusting an adjustable component of the headlight (in particular a light module) relative to an outer housing of the headlight. Here, the adjusting mechanism comprises an inner adjusting shaft, which is designed for adjusting the adjustable component, and the adjusting shaft according to the invention, the pinion engages in a ring gear of the inner actuating shaft. Thus, in the assembled condition, the pinion cooperates with the corresponding gear rim of the inner actuator shaft, which in turn acts on a reflector or other adjustable component of the headlight to adjust its positioning or alignment. PI2474
    Advantageous developments of the setting mechanism correspond to those of the adjusting shaft according to the invention. In particular, the housing may have a shoulder which is designed to correspond with a shoulder rotating on the shaft of the adjusting shaft, wherein a space for receiving and holding a sealing ring is formed between these two shoulders.
    The invention together with further advantages and features will be explained in more detail below with reference to a non-limiting embodiment, namely a bevel pinion shaft with a bevel gear for emplacing a light module of a headlamp, which is shown in the accompanying drawings. These show:

    In Fig. 1, a bevel pinion shaft 1 is shown, which realizes the adjustment shaft according to the invention in the embodiment It should be noted at this point that the invention is not limited to the embodiment described herein; Rather, the invention includes all embodiments of a setting shaft, which fall within the scope of the appended claims.
    The bevel pinion shaft 1 is designed as a component of an adjustment mechanism 3 (FIG. 3) of a vehicle headlamp and designed with its specific features specifically for this purpose. It is divided into a head part 11 and a body part or shaft 12 which extends along a longitudinal axis c and at the end of a pinion gear 13 in shape

    ft ft ft ft ft ft ft ft ft ft ft ft ft. * ft ft. * ft ft. of the bevel gearwheel is provided. The pinion gear 13 is called here also short pinion. The bevel pinion shaft 1 has a length of about 35 mm, measured along the axis c as a distance between the end face of the head part 11 and the opposite end of the shaft 12, and a diameter of the head part 11 of about 30 mm.
    If, in the context of this description, the terms " top " and "below" with respect to the adjusting shaft according to the invention and more specifically to the bevel pinion shaft, these refer to the component itself, notwithstanding the orientation thereof in the assembled state, with the longitudinal axis c being vertical and the head part 11 "top". is located and the opposite end of the shaft 12 after "down". has.
    Referring to FIG. 2, the bevel pinion shaft 1 according to the invention is inserted into an opening 20 of the housing 2 of the headlamp (of which only a part is shown in FIG. 2 as well as in FIGS. 3 and 6). In the position thus mounted, the head part 11 is the externally accessible part of the bevel pinion shaft 1 and thus the entire adjustment mechanism. Preferably, the bevel pinion shaft 1 is equipped with an O-ring 14, which ensures a sealing of the housing at the location of the bevel pinion shaft 1 and the opening 20 provided therefor. The O-ring 14 is shown cut in Fig. 1. During assembly, the O-ring 14 is first preassembled by being placed on the shaft 12 of the bevel pinion shaft 1, and then the latter together with the O-ring inserted into the opening 20 and latched, as explained in more detail below, the head part 11th locked at the outer edge of the opening 20.
    In Fig. 3 and 4, the adjusting mechanism 3 is shown, in addition to the bevel pinion shaft 1 a cooperating with this adjustment screw 31 belongs. The adjusting mechanism 3 is housed in the housing (outer housing) 2 of a headlamp. In the assembled state, the bevel pinion shaft 1 about its longitudinal axis c, which is vertical here, rotatable and, as already mentioned from the outside accessible (namely on the basis of the head part 11, which lies in the mounted state outside the housing 2) to a setting of an inside the Housing accommodated to be set component of the headlamp, in particular a light module or reflector of the headlamp to allow. For this purpose, the pinion 13 engages in a counter gear 33, namely a corresponding gear rim of the adjusting screw 31, which extends along an axis h, for example, horizontal. The bevel pinion shaft 1 thus acts in terms of gear on the adjusting screw 31, which serves as an inner actuating shaft according to the invention. Turning the adjusting screw 31 will cause a change in the position of the PI2474 PI2474 ♦♦ ·· 4 · 4 · 4 4 4 4 4 4 4 4 4 4 4 * 44 4 · -6- 4 · 4 44 4 4 4 4 4 4 4 4 4 4 4 4 4 4 ** 4 444 4 4 4 4 444 44 444 * 4
    Adjusting screw geared offset (here, for example, via a worm gear) adjusting block 32 which is in the housing 2, for. is mounted linearly displaceable and with the light module to be adjusted, such. In general, the control block is a component that can be fixed, articulated or geared to an adjustable component of the headlight.
    Referring again to FIG. 1, the stem has a substantially rotationally symmetric basic shape, here "substantially rotationally symmetric". means that the shaft may have slight deviations (not shown here) from a rotationally symmetrical shape (such as point-like notches or axially extending slot pitches) which do not affect the rotatability of the bevel pinion shaft 1 about the longitudinal axis c. In the embodiment shown in the drawings, the shaft 12 is rotationally symmetrical except, of course, the pinion 13. The shaft 12 has successively a first guide surface 15, a shoulder 16, a cylindrical portion 17 and a second guide surface 18. The cylindrical portion 17 serves as a seat of the O-ring 14, the position of which is limited to the head part 11 from the shoulder 16. The guide surfaces 15, 18 each have a conical shape with a slight angle of inclination with respect to the axis c. The guide surface 18 forms in its end region at the same time the outer boundary of the pinion 13. The pinion 13 preferably has an odd number of serrations, in the embodiment e.g. 11 Zahnungen, wherein generally the number of teeth of the pinion depends on the dimensioning of the own diameter of the pinion and the adjusting screw 31.
    In the sectional view of Fig. 5 is shown how the bevel pinion shaft 1 is mounted in the housing 2. The cutting plane here is the median plane of the adjustment mechanism, namely that plane which extends through the longitudinal axis c of the bevel pinion shaft 1 and parallel to the axis h of the adjusting screw 31; if, as in the embodiment shown, the axes c and h intersect, both longitudinal axes lie in the median plane.
    The opening 20 has a substantially tubular shape and is open at the lower end to allow engagement of the pinion 13 in the counter pinion 33 of the adjusting screw 31. The two guide surfaces 15,18 of the bevel pinion shaft 1 abut respectively associated hollow cone sections 25, 28, which are formed on the inside of the opening 20. Due to the conical design of the guide surfaces 15,18 give the sections 25, 28 of the housing independently of each other in each case a self-centering guide, which excludes tilting of the bevel pinion shaft 1 relative to the desired position of the axis c and ensures a stable and secure fit of the bevel pinion shaft 1. This advantageously also leads to improved reliability of the adjustment mechanism.
    Between the hollow cone sections 25, 28 a shoulder 26 is formed. The shoulder 26 is opposite the shoulder 16 of the bevel pinion shaft 1; In this case, the two shoulders 16,26 are preferably arranged so that they are offset in height from each other. Thus, the two shoulders 16, 26 define a space in which the O-ring 14 can be accommodated. In this way, a seat of the O-ring is advantageously defined without a groove for the O-ring must be provided. The distance between the shoulders 16, 26 is preferably greater than the radial width of the shoulder, which here by radial width means the change of the half-diameter at the shoulder, and sets the strand diameter of the O-ring 14. By this measure, the O-ring 14 seals in the radial direction between the cylindrical portion 17 and the surrounding part of the housing, but can be moved in the axial direction. Thus, the O-ring does not have to absorb forces acting on the bevel pinion shaft 1, e.g. be set when adjusting by an inserted tool in the axial direction.
    In addition, the shank 12 of the bevel pinion shaft 1 between the shoulder 16 and the guide surface 15 has an intermediate region 19 which has a diameter offset from the conical section, in this case a slightly smaller diameter (eg 0.2 to 0.3 mm ) as the guide surface 15. This intermediate region serves as an exemption in the assembled state of the bevel pinion shaft 1, for an increased tolerance to possible deviations occurring in the manufacture of the component.
    The adjusting shaft according to the invention may advantageously be made of injection-moldable material, e.g. thermoplastic. In particular, the shown bevel pinion shaft 1 is produced from polybutylene terephthalate (PBT) or a polyamide (PA). For injection molding, casting tools and casting methods are used in a manner known per se. The housing 2 consists e.g. made of thermoplastic or thermoset material, but can also be made of metallic material, in particular aluminum.
    It should be noted that the bevel pinion shaft 1 is a producible in a single casting process component, thus the head part 11 with the shaft 12 and the pinion 13 one-piece P12474 ·····. In addition, the shape of the substantially rotationally symmetrical shaft 12 is selected so that its specific shape can be generated by a single casting tool. The shaft 12 has, according to the requirement of avoiding a tool division, continuously decreasing diameter as one proceeds from the neck of the shaft at the transition to the head towards the lower end: the diameter always decreases - possibly also leaps and bounds, as in the place of the shoulder 16 - or may also in one or more defined areas - like the cylindrical portion 17 - remain the same, but does not increase toward the end facing away from the head part 11 anywhere. For example, in the cylindrical portion 17, the diameter D (Fig. 4) of the shank may be 15 mm, and then decreases in the area of the guide face 18 according to the inclination of the conical shape, in this case e.g. with an inclination of 2 ° from 15 mm to 14.6 mm. (Of course, the diameter is measured transversely to the axis c of the shaft.)
    Referring to Figs. 5 and 6, the head portion 11 has a shape which allows operation of the bevel pinion shaft 1, namely directly by hand and / or by means of an external tool. For this purpose, the head part 11 on the outside, in particular the (upward facing) end face, a projection 29 for an external tool. The projection 29 is preferably designed as a depth stop for an external tool and protrudes into the head part 11 and possibly into a part of the shaft 12 centrally along the longitudinal axis c. The depth projection 29 thus provides an externally accessible approach to an external tool, e.g. an Allen key and / or a screwdriver; for this he has e.g. the shape as an internal hexagon and at the end face of a slot / Phillips / Stem (Torx particular) as entrainment on. In addition, the shape of the head part 11 with its protruding locking hooks is also well suited as a manual adjusting knob for direct handling of the bevel pinion shaft 1 with the fingers of one hand.
    The depth stop 29 also reduces the amount of material necessary for the production of the component of the bevel pinion shaft 1. Also to reduce the material cost is at the end of the shaft 12, inside the helical toothing of the pinion 13, an axially inwardly extending recess 30 is formed, so that the component is largely hollow.
    Still referring to Figs. 5 and 6, the head portion 11 is formed so that a locking of the bevel pinion shaft 1 at the opening 20 is possible. The head part 11 has a face ♦ »··· PI2474 ♦» ·· · PI2474 • *

    Number, here six, Verrasthaken 21 on. Each latching hook has the shape of a protruding from the longitudinal axis c outward projection or cantilever, which is bent back in the manner of a brim and on which a to the shaft 12 oriented latching means 22 is located. The latching means 22 has e.g. the shape of a nose, which is attached to an inner side of the brim-like edge of Verrasthakens 21. The latching means 22 engages under the outer edge 24 of the opening 20, which is designed for this purpose a slightly outwardly projecting, namely around the entire circumference of the outer edge 24 or only on a part of the circumference, for example, corresponding to a sector of about 180 °.
    So that the latching means 22 can be produced in a mold without a so-called slide, an offset opening 23 is formed in the latch hook 21, which is located above the latching means 22. Due to this offset opening 23, the latching means 22 is seen from above, i. seen in the direction parallel to the longitudinal axis c on the head part 11 (more precisely, the front side), exposed. Herein, "exposed" means that the latching means 22 is entirely visible from above (in a projection parallel to the axis c upwards, it lies completely within the area formed by the border of the offset opening). Thus, the locking means 22 can be generated in a mold and be removed from this in a simple manner along the offset opening corresponding escape.
    The number of locking hooks is six in the embodiment shown, but may generally be chosen arbitrarily; e.g. two, three, five or seven.
    The invention enables a simplified design of the casting tool for the production of the component of the setting shaft, which allows a more rapid and cost-effective production. Due to the diameter decreasing towards the end of the shank, it is now possible to form the shank in a single shaping part of the casting mold. This avoids that caused by joints of the mold separation marks on the shaft, which usually adversely affect the sealing properties. Previous designs of the adjustment shaft had shoulders of increasing diameter, in particular in the form of a circumferential groove, which required a division of the casting tool in this area. In particular, when using an O-ring this was unfavorable; in the solution according to the invention, the area of the O-ring is free of a tool split, which improves the quality of the tightness and increases the life of the O-ring.

    The further development features of the invention additionally support the advantageous properties of the invention. In particular, the arrangement of the O-ring between two opposite shoulders of the shaft on the one hand and the inside of the housing opening on the other hand gives special advantages, since this makes a groove for holding an O-ring superfluous and, as already mentioned, the assembly and lifetime of the O-ring improved.
    Due to the mutually offset shoulders also results in a relief of accuracy requirements, since the inventive design allows a large variation in the relative position of the shoulders 16 and 26 to each other.
    Due to the arrangement of the latching elements on the outside, i. At an area of the adjustment shaft remote from the shaft, not only an even more favorable design of the shaft and thus simplified manufacture during injection molding, but also a circumferential latching, which is simpler and at the same time more robust, since in the case of conventional adjustment shafts internal locking devices are relatively filigree. In addition, the use of the adjusting shaft according to the invention with this latching is also possible with rigid housings (thermoset, Ahiminium die-cast).
    Of course, those skilled in the art will be able to design many other equivalent forms of the adjustment shaft and this may make modifications and / or additions to the needs of the case. Thus, for example, the pinion of the single-part shaft according to the invention may also have designs other than a bevel gear, e.g. as spur or crown wheel; In addition, the axes of the adjusting shaft and the inner adjusting shaft (adjusting screw) parallel and / or offset from each other. 0
    Further variations are already explained in connection with the embodiment described above.
