Description

Die Erfindung betrifft ein Projektionsmodul für einen Fahrzeugscheinwerfer mit einem Reflektor, mit einer dem Reflektor zugeordneten Lichtquelle, mit einer dem Reflektor in Abstrahlrichtung vorgelagerten Linse, mit einer zwischen der Lichtquelle und der Linse angeordneten feststehenden Fernlichtblende und einer der Fernlichtblende zur Linse hin vorgelagerten quer zur Längsachse in den Strahlengang einschwenkbaren Schaltblende für Abblendlicht, die über eine Lagerung mit der Fernlichtblende verbunden ist.The invention relates to a projection module for a vehicle headlight a reflector, with a light source assigned to the reflector, with a Lens in front of the beam, with one between the light source and the lens arranged fixed high beam and one of the High beam diaphragm in front of the lens transversely to the longitudinal axis in the beam path retractable control panel for low beam, which has a bearing with the main beam is connected.

Aus der DE 198 58 225 A1 und aus der DE 199 08 642 sind Projektionsmodule für Fahrzeugscheinwerfer bekannt, die einen Reflektor mit einer ihm zugeordneten Lichtquelle aufweisen, in dessen Strahlengang eine Linse angeordnet ist. Zwischen Reflektor und Linse ist quer zur Längsachse in einer vertikalen ersten Ebene eine feststehende Fernlichtblende angeordnet. Der Fernlichtblende ist zur Linse hin eine quer zur Längsachse in den Strahlengang einschwenkbare Schaltblende zur Erzeugung eines Abblendlichtes vorgelagert. Die Schaltblende ist dabei über eine Lagerung, die im Wesentlichen aus einer an der Fernlichtblende befestigten Lagerachse besteht, über ein spezielles Befestigungsteil zur axialen Lagesicherung drehbar mit der Fernlichtblende verbunden.DE 198 58 225 A1 and DE 199 08 642 are projection modules for Vehicle headlights known that have a reflector associated with it Have light source, in the beam path of which a lens is arranged. Between The reflector and lens is transverse to the longitudinal axis in a vertical first plane a fixed high beam aperture arranged. The high beam aperture is towards the lens a switching panel that can be swiveled into the beam path transversely to the longitudinal axis upstream to generate a low beam. The control panel is included via a bearing, which essentially consists of one attached to the high beam hood Bearing axis exists, via a special fastening part for axial position securing rotatably connected to the main beam.

Nachteilig bei dieser Anordnung, die sich grundsätzlich bewährt hat, ist, dass die Lagerung aus mehreren Teilen besteht, so dass ein automatisierter Montageablauf nur schwer zu gewährleisten ist und die Montage relativ kostenintensiv ist. Durch die verwendeten Metallteile ist eine exakte und reibungsarme Lagerung nur sehr schwer kostengünstig zu erzielen.A disadvantage of this arrangement, which has proven itself in principle, is that the Storage consists of several parts, so that an automated assembly process is difficult to guarantee and the assembly is relatively expensive. Due to the metal parts used, an exact and low-friction storage is only possible very difficult to achieve inexpensively.

Weiterhin ist aus der DE 44 07 108 A1 ein Projektionsmodul für einen Fahrzeugscheinwerfer bekannt, das eine Blendenanordnung aufweist, die aus einer feststehenden Fernlichtblende und einer zwischen zwei Endstellungen schwenkbaren Schaltblende ausgebildet ist. Die Schaltblende ist mittels einer Schneidenlagerung an der Fernlichtblende schwenkbar gelagert, wobei die Fernlichtblende einen Lagerbock mit einem seitlichen Schlitz aufweist und die Schaltblende eine Nase, die in den Schlitz eingreift. Aus der Fernlichtblende sind mehrere bügelartige Halter ausgestellt. Zwischen den Haltern und der Fernlichtblende wird die Schaltblende in einer Ebene senkrecht zur optischen Achse geführt. Zwischen der Fernlichtblende und der Schaltblende ist eine c-förmige Feder eingespannt, die die Schaltblende in ihren beiden Endstellungen gegen einen Anschlag hält.Furthermore, DE 44 07 108 A1 describes a projection module for a vehicle headlight known that has an aperture assembly consisting of a fixed High beam and a swivel between two end positions Switch panel is formed. The control panel is by means of a cutting edge bearing pivotally mounted on the high beam cover, the high beam cover a bearing block has a side slot and the control panel has a nose that engages in the slot. From the high beam cover are several bracket-like holders issued. The switch panel is located between the brackets and the main beam cover guided in a plane perpendicular to the optical axis. Between the high beam and the control panel is clamped in a c-shaped spring that holds the control panel holds against a stop in its two end positions.

Nachteilig ist hierbei ebenfalls, dass die Montage relativ kostenintensiv und nur schwer zu automatisieren ist. Eine exakte und reibungsarme Lagerung ist auch hier nur sehr schwer zu verwirklichen.Another disadvantage is that the assembly is relatively expensive and only is difficult to automate. An exact and low-friction storage is also very difficult to achieve here.

Aufgabe der vorliegenden Erfindung ist es daher, die bekannten Projektionsmodule so zu verbessern, dass die Lagerung der Schaltblende kostengünstig bei exakter und reibungsarmer Lagerung verwirklicht werden kann. Zudem soll ein kostengünstiger automatisierter Montageablauf gewährleistet werden.The object of the present invention is therefore the known projection modules to improve so that the storage of the control panel inexpensively with exact and low-friction storage can be realized. It is also said to be an inexpensive one automated assembly process can be guaranteed.

Diese Aufgabe wird erfindungsgemäß in Verbindung mit dem Oberbegriff des Anspruches 1 dadurch gelöst, dass die Lagerung aus einem hülsenförmigen Lagerelement aus Kunststoff, das an die aus Metall ausgebildete Fernlichtblende angespritzt ist, sowie aus einer Lagerhülse aus Kunststoff besteht, die an die aus Metall ausgebildete Schaltblende angespritzt ist und die auf das hülsenförmige Lagerelement aufsteckbar ist.This object is achieved in connection with the preamble of the claim 1 solved in that the storage from a sleeve-shaped bearing element made of plastic, which is molded onto the high-beam aperture made of metal is, and consists of a bearing sleeve made of plastic, which to the metal trained control panel is injection molded and onto the sleeve-shaped bearing element is attachable.

Dadurch, dass die Lagerung aus zwei Kunststoffteilen besteht, die an die Blenden angespritzt werden, können die Blenden kostengünstig als Metall-Kunststoff-Verbundteile in der sogenannten Outsert-Technik hergestellt werden. Dies ermöglicht eine einfache und automatisierbare Montage, da lediglich die Schaltblende mit ihrer Lagerhülse auf das hülsenförmige Lagerelement der Fernlichtblende aufgesteckt werden muss. Durch die Kunststoffteile wird zugleich eine exakte und reibungsarme Lagerung ermöglicht.Because the storage consists of two plastic parts attached to the panels molded on, the panels can be inexpensively as metal-plastic composite parts are manufactured using the so-called outsert technique. this makes possible a simple and automatable assembly, since only the switch panel with its bearing sleeve attached to the sleeve-shaped bearing element of the high-beam aperture must become. Due to the plastic parts, an exact and enables low-friction storage.

Gemäß einer bevorzugten Ausführungsform der Erfindung sind das Lagerelement und die Lagerhülse in axialer Richtung formschlüssig gegeneinander gesichert.According to a preferred embodiment of the invention, the bearing element and the bearing sleeve is positively secured against one another in the axial direction.

Durch die formschlüssige Verbindung von Lagerelement und Lagerhülse wird zudem eine axiale Sicherung ohne zusätzlich Sicherungsteile ermöglicht.The positive connection between the bearing element and the bearing sleeve also enables axial locking without additional locking parts.

Nach einer weiteren bevorzugten Ausführungsform der Erfindung weist das hülsenförmige Lagerelement einen zapfenförmigen Ansatz auf, dessen Außendurchmesser auf den Innendurchmesser der Lagerhülse abgestimmt ist und dessen umlaufender Bund einen Anschlag für das vordere Ende der Lagerhülse bildet. Der zapfenförmige Ansatz weist an seiner der Fernlichtblende abgewandten Stirnwandung eine Aussparung auf, in die zwei Haken der Lagerhülse einsetzbar sind, die nach Verdrehen die Stirnwandung formschlüssig hintergreifen.According to a further preferred embodiment of the invention, the sleeve-shaped Bearing element on a peg-shaped approach, the outer diameter is matched to the inside diameter of the bearing sleeve and its circumferential collar forms a stop for the front end of the bearing sleeve. The cone-shaped approach points away from the high beam aperture End wall a recess in which two hooks of the bearing sleeve can be inserted are that positively engage behind the end wall after twisting.

Durch den umlaufenden Bund des zapfenförmigen Ansatzes ist die Schaltblende mit ihrer Lagerhülse in axialer Richtung einfach zu positionieren. Dadurch, dass zwei zweckmäßigerweise einander gegenüberliegende Haken der Lagerhülse in die Aussparung der Stirnwandung einsetzbar sind, kann die Lagerhülse in einer bestimmten Position einfach auf den zapfenförmigen Ansatz des hülsenförmigen Lagerelementes aufgesetzt werden. Durch Verdrehen der Lagerhülse bzw. der Schaltblende in ihre Arbeitsposition erfolgt automatisch eine Lagesicherung in axialer Richtung, da die zwei Haken der Lagerhülse die Stirnwandung des zapfenförmigen Ansatzes formschlüssig hintergreifen.Due to the circumferential collar of the peg-shaped extension, the control panel is easy to position with its bearing sleeve in the axial direction. As a result of that two conveniently opposite hooks of the bearing sleeve in the recess of the end wall can be used, the bearing sleeve in one certain position simply on the peg-shaped neck of the sleeve-shaped Bearing element are placed. By turning the bearing sleeve or Switch panel in its working position automatically locks the position in axial direction, since the two hooks of the bearing sleeve cover the end wall of the peg-shaped Take a positive approach.
