Abstract
Description
Die Erfindung betrifft eine Abdeckblende für einen Linsenkörper einer Beleuchtungsvorrichtung für Fahrzeuge, wobei die Abdeckblende einen umlaufenden Rand des Linsenkörpers abdeckt.The invention relates to a cover panel for a lens body of a lighting device for vehicles, wherein the cover panel covers a peripheral edge of the lens body.
Aus der
Aufgabe der vorliegenden Erfindung ist es, eine Abdeckblende für einen Linsenkörper einer Beleuchtungsvorrichtung für Fahrzeuge derart weiterzubilden, dass eine langzeitstabile und homogene Randabdeckung eines Linsenkörpers gewährleistet ist. Object of the present invention is to develop a cover for a lens body of a lighting device for vehicles such that a long-term stable and homogeneous edge coverage of a lens body is guaranteed.
Zur Lösung dieser Aufgabe ist die Erfindung in Verbindung mit dem Oberbegriff des Patentanspruchs 1 dadurch gekennzeichnet, dass der Linsenkörper und/oder die Abdeckblende Rastmittel aufweisen zur Bildung einer unlösbaren Rastverbindung zwischen der Abdeckblende und dem Linsenkörper. To solve this problem, the invention in conjunction with the preamble of
Der besondere Vorteil der Erfindung besteht darin, dass durch die erfindungsgemäße Rastverbindung zwischen einer Abdeckblende und einem Linsenkörper eine direkte Verbindung zwischen der Abdeckblende und dem Linsenkörper gewährleistet ist, die eine dauerhafte und eindeutige Umrahmung des Linsenkörpers ermöglicht. Durch die direkte Verbindung der Abdeckblende an dem Linsenkörper wird eine eindeutige Relativposition derselben zueinander festgelegt, die eine Abdeckung mit einem konstanten Fugenverlauf ermöglicht. Nach der Erfindung sind die Rastmittel der Abdeckblende und/oder des Linsenkörpers derart ausgebildet, dass die Abdeckblende unlösbar mit dem Linsenkörper verbunden ist. Ein Lösen der Verbindung ist nur unter Zerstörung der Rastmittel möglich. Vorteilhaft ist hierdurch eine sichere Verbindung zwischen der Abdeckblende und dem Linsenkörper gewährleistet. The particular advantage of the invention is that a direct connection between the cover and the lens body is ensured by the locking connection according to the invention between a cover and a lens body, which allows a permanent and clear framing of the lens body. The direct connection of the cover to the lens body a unique relative position thereof is set to each other, which allows a cover with a constant joint profile. According to the invention, the locking means of the cover and / or the lens body are formed such that the cover is permanently connected to the lens body. A release of the connection is possible only with destruction of the locking means. This advantageously ensures a secure connection between the cover panel and the lens body.
Nach einer Weiterbildung der Erfindung weist der Linsenkörper einen bauchigen Linsenabschnitt und einen flachen Nichtlinsenabschnitt auf. Rastmittel zur Befestigung der Abdeckblende an dem Linsenkörper sind im Bereich des Nichtlinsenabschnitts angeordnet. Vorteilhaft bildet der Nichtlinsenabschnitt einen erweiterten Bereich des Linsenabschnitts, der zur Abdeckung von in dem Gehäuse des Scheinwerfers angeordneten Bauteilen genutzt werden kann. Der Nichtlinsenabschnitt hat somit mehrere Funktionen. Er dient zum einen der Förderung eines homogeneren Erscheinungsbildes des vorzugsweise eine asphärische Linse enthaltenden Linsenabschnitts, da er einen stetigen Übergang von dem Linsenabschnitt zu einem umlaufend Rand des Linsenkörpers ermöglicht. Darüber hinaus wirkt er der Einsehbarkeit in den Gehäuseinnenraum des Scheinwerfers von außen entgegen. Er hat somit eine Abdeckfunktion, wenn auch diese im Vergleich zur Abdeckblende relativ gering ist. Ferner hat der Nichtlinsenabschnitt eine Befestigungsfunktion für den eigentlichen Linsenabschnitt, da randseitig des Nichtlinsenabschnitts die Verrastung mit der Abdeckblende erfolgt. Vorteilhaft sind hierdurch die Befestigungspunkte relativ weit von dem Linsenabschnitt beabstandet angeordnet. According to a development of the invention, the lens body has a bulbous lens section and a flat non-lens section. Locking means for fixing the cover panel to the lens body are arranged in the region of the non-lens portion. Advantageously, the non-lens portion forms an extended area of the lens portion, which can be used to cover disposed in the housing of the headlight components. The non-lens section thus has several functions. It serves, on the one hand, to promote a more homogeneous appearance of the lens section, which preferably contains an aspherical lens, since it allows a continuous transition from the lens section to a circumferential edge of the lens body. In addition, it counteracts the visibility in the housing interior of the headlamp from the outside. He thus has a covering function, although this is relatively low compared to the cover. Furthermore, the non-lens section has a fastening function for the actual lens section, since the edge of the non-lens section is latched to the cover panel. Advantageously, thereby the attachment points are arranged relatively far from the lens portion.
Nach einer Weiterbildung der Erfindung ist das Rastmittel der Abdeckblende als ein an die Abdeckblende angeformtes Rastelement ausgebildet, das in der Montageposition eine Randkante des Linsenkörpers hintergreift, so dass eine einfache und sichere Befestigung gewährleistet istAccording to a development of the invention, the locking means of the cover is formed as a molded-on the cover panel locking element, which engages in the mounting position, a peripheral edge of the lens body, so that a simple and secure attachment is guaranteed
Nach einer Weiterbildung der Erfindung sind mehrere Rastmittel der Abdeckblende verteilt in einem zu dem Nichtlinsenabschnitt des Linsenkörpers korrespondierenden Bereich der Abdeckblende angeordnet. Durch die verteilte Anordnung ist eine sichere und dauerhafte Befestigung gewährleistet. According to a development of the invention, a plurality of latching means of the cover panel are arranged distributed in a region of the cover panel corresponding to the non-lens portion of the lens body. The distributed arrangement ensures a secure and permanent attachment.
Nach einer Weiterbildung der Erfindung ist die Wandstärke der Abdeckblende derart gewählt, dass die Rastmittel in der Montageposition von einer Vorderseite her nicht erkennbar sind. Der Scheinwerfer weist somit ein homogenes Erscheinungsbild auf. According to a development of the invention, the wall thickness of the cover is chosen such that the locking means in the mounting position from a front side are not visible. The headlight thus has a homogeneous appearance.
Weitere Vorteile der Erfindung ergeben sich aus den weiteren Unteransprüchen. Further advantages of the invention will become apparent from the further subclaims.
Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand der Zeichnungen näher erläutert. An embodiment of the invention will be explained in more detail with reference to the drawings.
