Abstract
Description
Die Erfindung betrifft eine Leuchteinheit für Fahrzeuge mit einem Leuchtengehäuse, in dem lichttechnische Komponenten angeordnet sind, und mit einer eine Lichtaustrittsöffnung des Leuchtengehäuses abschließenden Abdeckscheibe, dass das Leuchtengehäuse als ein energieabsorbierendes Deformationsteil ausgebildet ist.The The invention relates to a lighting unit for vehicles with a light housing, in the lighting components are arranged, and with a one Light opening of the luminaire housing final Cover that the luminaire housing as an energy absorbing Deformation part is formed.
Aus
der
Aufgabe der vorliegenden Erfindung ist es, eine Leuchteinheit für Fahrzeuge derart weiterzubilden, dass den gesteigerten Anforderungen an das Crashverhalten Rechnung getragen wird.task The present invention is a lighting unit for vehicles in such a way that the increased demands on the crash behavior Account is taken.
Zur Lösung dieser Aufgabe ist die Erfindung in Verbindung mit dem Oberbegriff des Patenanspruchs 1 dadurch gekennzeichnet, dass eine Wandung des Leuchtengehäuses mindestens zwei unterschiedliche Wanddicken aufweist, derart, dass die durch das Leuchtengehäuse aufzunehmenden Stoßkraftspitzen unterhalb einer vorgegebenen Grenzkraft liegen.to solution This object is the invention in conjunction with the preamble of claim 1, characterized in that a wall of the lamp housing has at least two different wall thicknesses, such that through the luminaire housing to be absorbed impact peaks lie below a predetermined limit force.
Der besondere Vorteil der Erfindung besteht darin, dass durch eine Variation der Wanddicken einer Wandung des Leuchtengehäuses gezielt das Energieabsorptionsverhalten der Leuchteinheit so beeinflusst wird, dass unerwünschte Stoßkraftspitzen unterhalb einer vorgegebenen Grenzkraft liegen. Vorteilhaft kann hierdurch ein gewünschtes Verformungsverhalten des Leuchtengehäuses geschaffen werden, beispielsweise kann bei einem Aufprall eines Fußgängers ein gewünschter Faltungseffekt entsprechend einem Knick im Hut (Kopfbedeckung) herausgebildet werden.Of the particular advantage of the invention is that by a variation the wall thicknesses of a wall of the luminaire housing targeted the energy absorption behavior the lighting unit is influenced so that unwanted impact peaks below a given limit force lie. This can advantageously a desired one Deformation behavior of the lamp housing are created, for example may be a desired one in a pedestrian impact Folding effect developed according to a kink in the hat (headgear) become.
Nach einer besonderen Ausführungsform der Erfindung ist ein erster Wandungsabschnitt als dünner Wandungsstreifen und ein zweiter Wandungsabschnitt als dicker Wandungsstreifen ausgebildet, wobei eine Mehrzahl von abwechselnd angeordneten dünnen und dicken Wandungsstreifen angeordnet sind. Während des Herstellungsvorgangs des Leuch tengehäuses durch Spritzgießen wird sich das Ausbilden von Bindenähten im Bereich der dünnen Wandungsstreifen zu nutze gemacht. Hierdurch erfahren die dünnen Wandungsstreifen eine weitere Schwächung, so dass sie bereits bei einer geringeren Kraft kollabieren. Der Grad der Materialschwächung kann hierdurch weiter verstärkt werden.To a particular embodiment of the Invention is a first wall portion as a thin wall strip and a second wall section formed as a thick wall strip, wherein a plurality of alternately arranged thin and thick wall stripes are arranged. During the manufacturing process of the Light housing by injection molding the formation of weld lines will be in the area of the thin wall strips made use of. This gives the thin wall strips a further weakening, so they collapse already at a lower force. Of the Degree of material weakening can thereby further reinforced become.
Nach einer Weiterbildung der Erfindung erstrecken sich die Wandungsstreifen in Auszugsrichtung des Spritzgießwerkzeuges, so dass der herstellungstechnische Aufwand unter Weglassen eines Schiebers verringert werden kann.To a development of the invention, the wall strips extend in the extension direction of the injection mold, so that the manufacturing technology Effort can be reduced by omitting a slider.
Nach einer Weiterbildung der Erfindung erstreckt sich der erste Wandungsabschnitt mit einer relativ geringen Wanddicke an einer oberen Wandung des Leuchtengehäuses. Damit werden gezielt Schwachstellen der Wandung dort erzeugt, wo das Energieabsorptionsverhalten der Leuchteinheit am günstigsten beeinflusst werden kann. Durch Wegfall bzw. Verringerung der Kraftspitzen kann eine erhebliche Verbesserung des Fußgängerschutzes ermöglicht werden.To In a further development of the invention, the first wall section extends with a relatively small wall thickness at an upper wall of the Luminaire housing. This weak points of the wall are generated specifically where the energy absorption behavior of the lighting unit most favorable can be influenced. By eliminating or reducing the force peaks a significant improvement in pedestrian protection can be made possible.
Weitere Vorteile der Erfindung ergeben sich aus den weiteren Unteransprüchen.Further Advantages of the invention will become apparent from the other dependent claims.
