Abstract

The headlight has a housing (2), and a light source and a lens (1) that is provided with an assembly edge (1b) that is made of plastic material. The assembly edge comprises an end section, which is formed of a cylinder shell-like part (7) and projected into a circulating frontal groove (8) of a housing section, or comprises a front-sided groove into which a sealing unit is projected. The sealing unit is rested opposite to the housing section, and the assembly edge is connected with the lens by an injection molding process or a foaming process using screws.

Description

Die Erfindung betrifft einen Scheinwerfer für Fahrzeuge und insbesondere die Befestigung der Lichtscheibe am Gehäuse, entsprechend dem Oberbegriff des Anspruches 1 und der EP 1 637 801 .The invention relates to a headlight for vehicles and in particular the attachment of the lens to the housing, according to the preamble of claim 1 and the EP 1 637 801 ,

Die EP 1 637 801 beschäftigt sich mit dem Problem der Erfindung, dass sich insbesondere dann stellt, wenn großflächige Lichtscheiben, wie sie derzeit im Fahrzeugbau verlangt werden, am Gehäuse des Scheinwerfers montiert werden müssen. Bei älteren Scheinwerfern gab es dabei keine Probleme, die Lichtscheiben aus Glasmaterial hatten umgebogene Ränder, die im Wesentlichen zylindrisch, wenn auch nicht kreiszylindrisch, zur Scheinwerferachse und damit zur Hauptstrahlrichtung verlaufen, und es war möglich, diese Ränder in nutenförmige Aufnahmen im Stirnbereich des Gehäuses einzustecken und darin entweder zu verkleben oder durch Schrauben, Klammern oder ähnliches zu fixieren. Entsprechender Stand der Technik ist in der DE 28 46 990 und der EP 589 189 zu finden. Bei den großflächigen Lichtscheiben ist eine derartige Umstülpung des Randes nicht möglich, und die eingangs genannte Druckschrift sieht daher vor, entlang des ebenen, im Wesentlichen lotrecht auf die Scheinwerferachse stehenden, flanschartigen Randes der Lichtscheibe einen Blendrahmen aufzukleben. Der Blendrahmen weist im Querschnitt im Wesentlichen L-Form auf und das Ende seines zylindrischen Abschnittes seinerseits wird dann, so wie die früheren Lichtscheiben für sich, in etwa in Richtung des Lichtstrahls in eine umlaufende Nut eines Basisteils eingesetzt und dort verklebt.The EP 1 637 801 deals with the problem of the invention, which arises in particular when large-area lenses, as they are currently required in vehicle construction, must be mounted on the housing of the headlight. In the case of older headlamps, there were no problems, the glass-fiber lenses had bent edges that were substantially cylindrical, though not circular, to the headlight axis and thus to the main beam direction, and it was possible to insert these edges into groove-shaped receptacles in the face of the housing and either glued or fixed by screws, clamps or the like. Corresponding prior art is in the DE 28 46 990 and the EP 589,189 to find. In the case of the large-area light disks, such an eversion of the edge is not possible, and the publication mentioned above therefore provides for gluing a window frame along the flat flange edge of the light disk, which is essentially perpendicular to the headlight axis. The frame has in cross-section substantially L-shape and the end of its cylindrical portion in turn is then, as the earlier light disks for themselves, used approximately in the direction of the light beam in a circumferential groove of a base part and glued there.

Diese Lösung weist verschiedene Nachteile auf: Vor allem die umlaufende Verklebung des Blendrahmens entlang des Randes der Lichtscheibe ist problematisch, da sie einerseits geometrisch äußerst genau erfolgen muss, andererseits unter all den rauen Einsatzbedingungen dicht bleiben muss. Wegen der sehr komplexen Umrissform der heute verwendeten Lichtscheiben, es wird dazu auf Fig. 1 der eingangs genannten Druckschrift verwiesen, ist die Einbringung der richtigen Menge an Klebstoff und auch das richtige Positionieren der Lichtscheibe bezüglich des Blendrahmens nicht einfach, sondern zeitraubend und trotzdem mit einem unangenehm hohen Anteil an Ausschuss verbunden. Dazu kommt, dass der Blendrahmen wegen der benötigten Klebefläche und Abdeckung verschiedenster Toleranzen eine gewisse Höhe (in der Strahlrichtung) benötigt, was vielfach unangenehm für die Gesamtkonstruktion und den Platzbedarf des Scheinwerfers als Ganzes ist.This solution has several disadvantages: Above all, the circumferential bonding of the frame along the edge of the lens is problematic because it must be geometrically extremely accurate on the one hand, on the other hand must remain tight under all harsh operating conditions. Because of the very complex outline of the lens used today, it is going on Fig. 1 referenced the above-mentioned document, the introduction of the correct amount of adhesive and also the correct positioning of the lens with respect to the frame is not easy, but time-consuming and still associated with an unpleasant amount of waste. On top of that, the frame is necessary because of the required adhesive surface and Covering a variety of tolerances requires a certain amount (in the beam direction), which is often uncomfortable for the overall design and space requirements of the headlamp as a whole.

Es besteht daher der Bedarf an einer Verbindung zwischen Lichtscheibe und Gehäuse, die die erwähnten Nachteile nicht aufweist, und, wenn es gewünscht wird, auch eine Ausführung mit lösbarer Verbindung zulässt und dabei gegenüber der derzeitigen Lösung keine gravierenden Mehrkosten verursacht.There is therefore a need for a connection between lens and housing, which does not have the mentioned disadvantages, and, if desired, also allows a version with detachable connection, thereby causing no major additional costs compared to the current solution.

Erfindungsgemäß werden diese Ziele durch die im kennzeichnenden Teil des Anspruches 1 angegebenen Merkmale erreicht, mit anderen Worten, es wird die Lichtscheibe in einem Spritzgussverfahren oder einem Schäumverfahren mit einem Montagerand aus Kunststoff versehen, der entweder einen zylindermantelartigen Endabschnitt aufweist, der bevorzugt im Wesentlichen parallel zur Scheinwerferachse verläuft und so die Montage in Richtung der Scheinwerferachse in eine umlaufende Stirnnut eines Gehäuseteils erlaubt, oder einen Endabschnitt aufweist, der eine stirnseitige Nut aufweist, in die eine Dichtung gegenüber einem Gehäuseteil eingelegt ist. So wie in den beiden oben angeführten älteren Druckschriften kann diese Verbindung eine nicht-lösbare Klebeverbindung sein, es kann sich aber auch um eine lösbare Verbindung, die mit Hilfe von Schrauben, Klammern oder sonstigen Verbindungselementen zusammen gehalten wird, handeln.According to the invention, these objects are achieved by the features stated in the characterizing part of claim 1, in other words, the lens is provided in an injection molding or a foaming with a mounting edge made of plastic, which either has a cylinder jacket-like end portion, which preferably substantially parallel to Headlight axis extends and allows the mounting in the direction of the headlight axis in a circumferential end groove of a housing part, or has an end portion having an end-side groove into which a seal against a housing part is inserted. As in the two earlier references cited above, this connection may be a non-releasable adhesive bond, but it may also be a releasable connection held together by means of screws, clips or other fasteners.

Die Erfindung wird im Folgenden anhand der Zeichnung näher erläutert. Dabei zeigt bzw. zeigen

  • die Fig. 1 eine erfindungsgemäße Verbindung zwischen einer Lichtscheibe mit einem Gehäuseteil und
  • die Fig. 2 eine Variante.
The invention will be explained in more detail below with reference to the drawing. It shows or show
  • the Fig. 1 a connection according to the invention between a lens with a housing part and
  • the Fig. 2 a variant.

Die Fig. 1 zeigt eine Lichtscheibe 1a, die mittels Spritzgussverfahren oder Schäumverfahren entlang ihrer Peripherie mit einem Montagerand 1b aus Kunststoff, beispielsweise aus Polyurethan, zu einer Abdeckscheibe 1 fest verbunden ist. Der Montagerand 1b weist einen Endabschnitt 7 auf, der im Wesentlichen zylindrische Form, wenn auch nicht kreiszylindrische Form aufweist und in jedem Axialschnitt, wie ihn auch die Fig. 1 zeigt, parallel zur Lichtrichtung L, zumeist zusammenfallend mit der Scheinwerferachse, verläuft. Es ist der Verlauf in Richtung L nicht zwingend notwendig sondern hängt von der Richtung beim Entformen bei der Herstellung und von der Richtung des Zusammenbaus des Scheinwerfers ab, für den Fachmann ist dies leicht an die Form des gesamten Scheinwerfers anzupassen. Dieser Endabschnitt 7 kann nun, so wie bei den früheren aufgebogenen Scheinwerfern deren Rand, in eine umlaufende Nut 8 an der Stirnseite eines Gehäuseteils 2 gesteckt und dort, beispielsweise durch einen Klebstoff 3, beispielsweise Silikon, Schmelzkleber oder einem Kleber auf der Basis von Polyurethan dauerhaft und dicht mit dem Gehäuseteil 2 verbunden werden.The Fig. 1 shows a lens 1a, which is fixedly connected by means of injection molding or foaming along its periphery with a mounting edge 1b made of plastic, such as polyurethane, to a cover 1. The mounting edge 1b has an end portion 7, which has a substantially cylindrical shape, although not circular cylindrical shape and in each axial section, such as him too Fig. 1 shows, parallel to the light direction L, usually coincident with the headlight axis, runs. It is the course in the direction of L is not mandatory but depends on the direction during demolding during manufacture and on the direction of assembly of the headlamp, for the skilled person this is easy to adapt to the shape of the entire headlamp. This end portion 7 can now, as in the previous headlamps bent edge thereof, inserted into a circumferential groove 8 on the front side of a housing part 2 and there permanently, for example by an adhesive 3, for example silicone, hot melt adhesive or an adhesive based on polyurethane and be tightly connected to the housing part 2.

Das Gehäuse selbst ist in der Fig. 1 nur mit seinem der Lichtscheibe benachbarten Abschnitt 2 angedeutet, desgleichen die Lichtkomponente 4 und die Lichtrichtung L, die, mit den oben genannten Adaptionsmöglichkeiten, zumindest im Wesentlichen parallel zur Strahlrichtung des Scheinwerfers verläuft.The case itself is in the Fig. 1 indicated only with its the lens adjacent section 2, as well as the light component 4 and the light direction L, which, with the above-mentioned adaptation options, at least substantially parallel to the beam direction of the headlamp.

Die Fig. 2 zeigt eine Variante mit lösbarer Verbindung zwischen Abdeckscheibe 1 und dem Gehäuseabschnitt 2, wobei der Montagerand 1b an seiner zum Gehäuse gerichteten Stirnfläche eine umlaufende Nut 8 aufweist, in die eine Dichtung 5 eingelegt oder eingeklebt ist. Diese Dichtung 5 drückt auf eine Stirnfläche 9 des Gehäuseabschnittes 2 und wird durch Schrauben 6, die im passenden Abstand voneinander entlang des Umfanges des Montagerandes 1b vorgesehen sind, gegen diese Stirnfläche gedrückt gehalten. Statt der Schrauben 6 können auch Klammern udgl, wie sie aus dem Stand der Technik, wie er eingangs erwähnt ist, bekannt sind, verwendet werden. Wesentlich ist auch hier, dass eine umlaufende Nut in einer Stirnfläche vorgesehen ist, und dass die Dichtung in der Nut erfolgt.The Fig. 2 shows a variant with detachable connection between the cover plate 1 and the housing portion 2, wherein the mounting edge 1b on its end face directed to the housing has a circumferential groove 8, in which a seal 5 is inserted or glued. This seal 5 presses on an end face 9 of the housing section 2 and is held pressed against this end face by screws 6, which are provided at the appropriate distance from one another along the circumference of the mounting edge 1b. Instead of the screws 6 and brackets udgl, as they are known from the prior art, as mentioned above, can be used. It is also essential here that a circumferential groove is provided in an end face, and that the seal is made in the groove.

Die erfindungsgemäße Lösung macht die Montage der Abdeckscheibe 1, bestehend aus der Glasscheibe 1 a und deren Montagerand 1b so einfach, sicher und zuverlässig, wie es ursprünglich bei den topfförmigen Glasscheiben der Fall war und vermeidet alle Nachteile des späteren Standes der Technik, obwohl großflächige und ebene oder gebogene Flachglasscheiben 1a verwendet werden. Dazu kommt noch, dass durch die die Scheibe umfassende Ausbildung des Montagerandes 1 b die Größe der Glasscheibe 1a bei ansonsten vergleichbaren Abmessungen kleiner gehalten werden kann als bei der eingangs genannten Druckschrift mit dem scheibenförmigen Kleberand, bei dem die Glasscheibe bis zu dessen Rand reichen musste, und dass die durch das Anspritzen bzw. Umspritzen bzw. Schäumen erzielte hohe Verbindungsfestigkeit zwischen Glasscheibe 1a und Montagerand 1b die Erstreckung des gesamten Gebildes in Richtung der Lichtstrahlen L und auch im rechten Winkel dazu deutlich geringer gehalten werden kann als im Stand der Technik.The solution according to the invention makes the assembly of the cover 1, consisting of the glass 1 a and their mounting edge 1b as simple, safe and reliable, as was the case originally with the cup-shaped glass and avoids all the disadvantages of the prior art, although large and flat or curved flat glass sheets 1a are used. In addition, the size of the glass pane 1a can be kept smaller than in the case of the otherwise comparable dimensions by the design of the mounting edge 1b that comprises the pane mentioned above document with the disc-shaped adhesive edge, in which the glass had to reach to the edge, and that achieved by the molding or encapsulation or foaming high bonding strength between glass pane 1a and mounting edge 1b the extension of the entire structure in the direction of the light rays L and at a right angle to this can be kept much lower than in the prior art.

Bei Wahl der Montagerichtung in Richtung der Scheinwerferachse bzw. der Lichtachse L können Abweichungen von bis zu 20° vorgenommen werden, ohne dass das als nicht mehr parallel angesehen wird. Bei größeren Abweichungen, die insbesondere bei den heute modernen, absolut nicht mehr kreissymmetrischen Formen der Gehäuse passend oder gar notwendig sind, erfolgt die Montage bzw bei der Herstellung das Ausformen einfach in anderer Richtung.When selecting the mounting direction in the direction of the headlight axis or the light axis L deviations of up to 20 ° can be made without that is considered no longer parallel. For larger deviations, which are particularly suitable or even necessary, especially in today modern, absolutely no longer circularly symmetrical shapes of the housing, the assembly or in the production of the molding is simply done in a different direction.
