Description
Die Erfindung betrifft eine Scheinwerfereinheit mit einer Schaltvorrichtung nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a headlight unit with a switching device according to the preamble of
Aus der DE 39 39 710 C 1 ist eine Schaltvorrichtung für einen Fahrzeugscheinwerfer bekannt. Der Fahrzeugscheinwerfer weist eine aus Reflektor, Blendenanordnung und Linse bestehende Einheit auf, die in ein von der Rückseite zu öffnendes Gehäuse eingesetzt ist. Zwischen dem Reflektor und der Linse ist die aus einer ortsfesten Blende und einer verstellbaren bzw. verschwenkbaren Blende bestehende Blendenanordnung eingesetzt, die durch eine Verstellvorrichtung in zwei Endstellungen einstellbar ist.From DE 39 39 710
Die verstellbare Blende wird durch einen zweiarmigen Betätigungshebel, welcher schwenkbar an dem Reflektorrand gelagert ist, verschwenkt. Das freie Ende des einen Armes des zweiarmigen Betätigungshebel ist mit einem Schlitz versehen, in den eine starr mit der Blende verbundene Zunge hineinragt, und das freie Ende des anderen Armes ist derart zweifach abgeknickt, dass der freie Endbereich des Armes, der der die Glühlampe, aufnehmenden Fassung benachbart ist und durch eine Öffnung, die an der Rückseite als Zugangsöffnung zum Reflektor ausgebildet ist, bedienbar ist.The adjustable aperture is pivoted by a two-armed actuating lever which is pivotally mounted on the reflector edge. The free end of the one arm of the two-armed actuating lever is provided with a slot into which a tongue rigidly connected to the panel projects, and the free end of the other arm is bent twice in such a way that the free end portion of the arm, that of the incandescent lamp, receiving socket is adjacent and through an opening which is formed on the back as an access opening to the reflector, can be operated.
Nachteilig bei der bekannten und grundsätzlich bewährten Schaltvorrichtung ist, dass sie zum einen relativ aufwendig und teuer ist, und dass sie zum anderen nicht für Reflektoren bzw. Abblendlichtscheinwerfer mit Gasentladungslampen, beispielsweise Xenonlampen, genutzt werden kann, da die Komponenten des Xenon-Abblendlichtes wegen der Zündung des Lichtbogens durch einen Hochspannungsimpuls als Sicherheitsteile eingestuft werden, bei denen ein Zugriff durch den Kunden unerwünscht ist und daher konstruktiv abgesichert werden, so dass ein Verschwenken der verschwenkbaren Blende über die Zugangsöffnung zum Abblendlichtscheinwerfer nicht mehr gegeben ist.A disadvantage of the known and basically proven switching device is that it is relatively complex and expensive, and that it can not be used for reflectors or low-beam headlamps with gas discharge lamps, for example xenon lamps, since the components of the xenon dipped-beam headlight are not Ignition of the arc can be classified by a high voltage pulse as security parts in which access by the customer is undesirable and therefore structurally secured, so that pivoting of the pivotable aperture on the access opening to the low beam headlight is no longer given.
Aus der EP 0 590 454 A2 ist eine Schaltvorrichtung für eine Blendenanordnung eines Scheinwerfers bekannt, die über eine verstellbare Blende und eine ortsfeste Blende verfügt. Die verstellbare Blende ist an der ortsfesten Blende verschwenkbar gelagert und in zwei Endstellungen arretierbar. Zum Betätigen der verstellbaren Blende ist ein Betätigungshebel vorgesehen, der innerhalb eines Gehäuses des Scheinwerfers angeordnet ist.From EP 0 590 454 A2 a switching device for a diaphragm arrangement of a headlamp is known, which has an adjustable aperture and a fixed aperture. The adjustable aperture is pivotally mounted on the stationary panel and can be locked in two end positions. To operate the adjustable aperture is an operating lever provided, which is arranged within a housing of the headlamp.
Aus der GB 2 279 452 A ist ebenfalls eine Schaltvorrichtung für eine Blendenanordnung eines Scheinwerfers offenbart, die eine ortsfeste Blende und eine verschwenkbare Blende aufweist. Die verschwenkbare Blende wird mittels eines Betätigungselementes bedient, das innerhalb des Gehäuses des Scheinwerfers angeordnet ist.From
Aus der DE 43 01 936 A1 ist eine Scheinwerfereinheit mit zwei benachbarten Fahrzeugscheinwerfern bekannt, denen jedoch keine Schaltvorrichtung für eine Blendenanordnung mit einer verstellbaren und verschwenkbaren Blende zugeordnet ist.From DE 43 01 936 A1 a headlamp unit with two adjacent vehicle headlights is known, which, however, is associated with no switching device for a diaphragm arrangement with an adjustable and pivotable aperture.
Die EP 0 381.851 A1 offenbart eine Schaltvorrichtung für eine Blendenanordnung, die dem Reflektor eines Fahrzeugscheinwerfers vorgelagert ist und über eine ortsfeste Blende und eine verschwenkbare Blende verfügt. Die verschwenkbare Blende ist über einen Steller verschwenkbar, der durch eine obere Öffnung einer Gehäusewand des Fahrzeugscheinwerfers bedienbar ist, wobei ein freies Ende des als Winkelhebel ausgebildeten Stellers durch diese Öffnung der Gehäusewand durchragt. Nachteilig an der bekannten Schaltvorrichtung ist, dass im Bereich einer Gehäusewand des der Schaltvorrichtung zugeordneten Fahrzeugscheinwerfers eine Öffnung vorgesehen sein muss.EP 0 381 851 A1 discloses a switching device for a diaphragm arrangement, which is disposed in front of the reflector of a vehicle headlight and has a stationary diaphragm and a pivotable diaphragm. The pivotable aperture is pivotable via a positioner which can be operated through an upper opening of a housing wall of the vehicle headlamp, with a free end of the actuator designed as an angle lever protrudes through this opening of the housing wall. A disadvantage of the known switching device is that an opening must be provided in the region of a housing wall of the vehicle headlight associated with the switching device.
Aufgabe der vorliegenden Erfindung ist es daher, eine Schaltvorrichtung für eine Blendenanordnung einer Scheinwerfereinheit enthaltend mindestens zwei Fahrzeugscheinwerfer so zu verbessern, dass sie einfach und kostengünstig herstellbar und von der Gehäuserückwand her, jedoch nicht über den geschützten Bereich des Reflektors, bedienbar ist.Object of the present invention is therefore to improve a switching device for a diaphragm assembly of a headlamp unit containing at least two vehicle headlights so that they can be easily and inexpensively manufactured and from the rear housing, but not over the protected area of the reflector operable.
Die Aufgabe wird mit den Merkmalen des Patentanspruchs 1 gelöst.The object is achieved with the features of
Dadurch, dass der Steller mit einem Ende fest mit der verschwenkbaren Blende verbunden ist, kann auf eine spezielle Schwenkachse für den Steller und eine zusätzliche Zunge, in die der Steller mit seinem freien Ende eingreift, verzichtet werden. Durch die Anordnung einer Öffnung an der Gehäuserückwand des benachbarten Fahrzeugscheinwerfers, die seitlich versetzt zu dem Reflektor bzw. zu dessen Zugangsöffnung angeordnet ist, wird zudem eine Bedienung über die Zugangsöffnung des zu schaltenden Fahrzeugscheinwerfers vermieden, so dass die Schaltvorrichtung auch für Abblendscheinwerfer mit Gasentladungslampen genutzt werden kann, bei denen eine Bedienung der Schaltvorrichtung über die geschützte Zugangsöffnung durch den Kunden nicht möglich bzw. nicht erwünscht ist.The fact that the actuator is connected at one end fixed to the pivotable aperture, can be dispensed with a special pivot axis for the actuator and an additional tongue into which the actuator with its free end. By arranging an opening on the housing rear wall of the adjacent vehicle headlight, which is laterally offset from the reflector or to its access opening, an operation via the access opening of the vehicle headlamp to be switched is also avoided, so that the switching device for low beam headlamps can be used with gas discharge lamps, in which an operation of the switching device on the protected access opening by the customer is not possible or not desirable.
Nach einer bevorzugten Ausführungsform der Erfindung ist die Öffnung an der Gehäuserückwand als Zugangsöffnung für einen Fernlichtscheinwerfer ausgebildet. Der Fernlichtscheinwerfer weist einen Reflektor auf, der dem Reflektor des Abblendlichtscheinwerfers in Fahrzeuglängsrichtung vorgelagert ist.According to a preferred embodiment of the invention, the opening is formed on the rear wall of the housing as an access opening for a high beam headlamp. The high beam headlamp has a reflector, which is upstream of the reflector of the low beam headlamp in the vehicle longitudinal direction.
Dadurch ist es möglich, auf eine zusätzliche Öffnung in der Gehäuserückwand zu verzichten und der Steller kann ohne besondere Abwinklungen in den Bereich der Zugangsöffnung hineinragen, so daß er von der Gehäuserückwand her über die Zugangsöffnung bedient werden kann.This makes it possible to dispense with an additional opening in the housing rear wall and the actuator can protrude without special bends in the region of the access opening, so that it can be operated from the rear wall of the case via the access opening.
Gemäß einer weiteren bevorzugten Ausführungsform der Erfindung ist der Steller mit seiner der Blende abgewandten Vorderseite einer vorderen Führungskante eines Halters und mit seiner der Blende zugewandten Rückseite einer hinteren Führungskante des Halters benachbart. Der Steller wird somit in einem Führungsschlitz, der von zwei Führungskanten gebildet wird, gegen Überdrücken gehalten.According to a further preferred embodiment of the invention, the actuator with its front side facing away from the front panel of a front leading edge of a holder and with its rear facing the rear panel of a rear leading edge of the holder adjacent. The actuator is thus held in a guide slot, which is formed by two leading edges against overpressure.
Nach einer weiteren bevorzugten Ausführungsform der Erfindung ist der Steller mit seiner dem Halter zugewandten Unterseite in einer unteren Stellung gegen eine untere Anschlagkante des Halters anschlagbar. Eine genau definierte Anschlagkante verhindert somit ein Überschalten.According to a further preferred embodiment of the invention, the actuator with its the holder-facing underside in a lower position against a lower stop edge of the holder can be stopped. A precisely defined stop edge thus prevents an overshift.
Gemäß einer weiteren bevorzugten Ausführungsform der Erfindung weist die verschwenkbare Blende an ihrem ihrer Schwenkachse abgewandten Ende einen Anschlag auf, der gegen eine in vertikaler Richtung obere Blendenkante der ortsfesten Blende anschlagbar ist. Dadurch ist eine genau definierte Anschlagkante für die zweite Schwenkstellung gegeben und ein Überschalten wird auch hier zuverlässig verhindert. Weitere Einzelheiten der Erfindung ergeben sich aus der nachfolgenden ausführlichen Beschreibung und den beigefügten Zeichnungen, in denen bevorzugte Ausführungsformen der Erfindung beispielsweise veranschaulicht sind.According to a further preferred embodiment of the invention, the pivotable diaphragm at its end facing away from its pivot axis has a stop which can be abutted against an upper edge of the stationary diaphragm in the vertical direction. As a result, a precisely defined stop edge for the second pivot position is given and an overshift is reliably prevented here. Further details of the invention will become apparent from the following detailed description and the accompanying drawings, in which preferred embodiments of the invention are illustrated, for example.
