Abstract
Description
Die Erfindung betrifft einen Scheinwerfer für Fahrzeuge mit einem Reflektor, einer Lichtquelle, die im Bereich einer Öffnung des Reflektors in einer Fassung gelagert ist, mit einer Verstelleinheit zur relativen Bewegung der Lichtquelle zu dem Reflektor in eine erste Abblendlichtposition und eine zweite Fernlichtposition und vice versa, dass die Verstelleinheit mindestens zwei im wesentlichen koaxial zu einer optischen Achse des Reflektors angeordnete Ringelemente aufweist.The invention relates to a headlight for vehicles with a reflector, a light source in the area of an opening of the Reflector is mounted in a version with an adjustment unit for the relative movement of the light source to the reflector in a first low beam position and a second high beam position and vice versa that the adjustment unit is at least two essentially Ring elements arranged coaxially to an optical axis of the reflector having.

Aufgabe der vorliegenden Erfindung ist es, einen Scheinwerfer für Fahrzeuge derart weiterzubilden, dass eine gleichmäßige und langzeitstabile Verstellung des Scheinwerfers in eine Abblendlichtposition und in eine Fernlichtposition gewährleistet ist.Object of the present invention is a headlight for Develop vehicles in such a way that a uniform and Long-term stable adjustment of the headlamp to a low beam position and is guaranteed in a high beam position.
Zur Lösung dieser Aufgabe ist die Erfindung in Verbindung mit dem Oberbegriff des Patentanspruchs 1 dadurch gekennzeichnet, dass die Ringelemente derart geformt sind, dass durch relatives Verdrehen mindestens eines Ringelementes um die optische Achse eine entlang des Umfangs der Gesamtanordnung der Ringelemente unterschiedliche axiale Erstreckung einstellbar ist zur Erzeugung einer kontinuierlichen Kippbewegung senkrecht zur optischen Achse.To solve this problem is the Invention in connection with the preamble of the claim 1 characterized in that the ring elements are shaped such that by relative rotation of at least one ring element the optical axis is one along the circumference of the overall arrangement different axial extent of the ring elements adjustable is vertical to produce a continuous tilting movement to the optical axis.
Der besondere Vorteil der Erfindung besteht darin, dass durch relatives Verdrehen eines oder mehrerer Ringelemente die Gesamtanordnung der Ringelemente in unterschiedlichen Umfangsbereichen eine unterschiedliche axiale Erstreckung erhält, so dass eine Kippbewegung senkrecht zur optischen Achse bewirkt wird. Grundgedanke der Erfindung ist es, eine Drehbewegung um eine optische Achse in eine Kippbewegung um eine senkrecht zur optischen Achse angeordnete Drehachse umzuwandeln. Die Erfindung ermöglicht ein sicheres, kontinuierliches und langzeitstabiles Verstellen von mindestens zwei unterschiedlichen Lichtfunktionspositionen.The particular advantage of the invention consists in the fact that by relative turning one or more Ring elements the overall arrangement of the ring elements in different Circumferential areas receives a different axial extent, so that a tilting movement perpendicular to the optical axis is effected. basic idea the invention is a rotational movement about an optical axis in a Tilting movement about an axis of rotation arranged perpendicular to the optical axis convert. The invention enables a safe, continuous and long-term stable adjustment of at least two different light function positions.
Nach einer bevorzugten Ausführungsform der Erfindung weisen zueinander gekehrte axiale Anlageflächen von zwei Ringelementen schraubenförmige Schrägflächen auf, die sich jeweils in einem Umfangsbereich von mindestens 90° erstrecken. Hierdurch wird vermieden, dass die Kippbewegung ruckartig verläuft. Es können somit unerwünscht hohe Stoßkräfte vermieden werden.According to a preferred embodiment of the Invention have mutually facing axial contact surfaces of two helical ring elements Inclined surfaces, which each extend in a circumferential area of at least 90 °. hereby it is avoided that the tilting movement is jerky. It can thus undesirably high Avoid impact forces become.
Nach einer vorteilhaften Ausführungsform der Erfindung sind zwei Ringelemente vorgesehen, wobei durch entgegengesetztes Verdrehen derselben zueinander eine Verstellung in die unterschiedlichen Lichtfunktionspositionen ermöglicht wird. Hierdurch kann besonders schnell eine kontinuierliche Bewegungsumwandlung erzeugt werden.According to an advantageous embodiment of the Invention, two ring elements are provided, whereby by opposite Twisting them to each other an adjustment in the different Light function positions enabled becomes. This enables continuous motion conversion to be carried out particularly quickly be generated.
Weitere Vorteile der Erfindung ergeben sich aus den weiteren Unteransprüchen.Further advantages of the invention result itself from the further subclaims.
Ausführungsbeispiele der Erfindung werden nachfolgend anhand der Zeichnungen näher erläutert.Embodiments of the invention are explained below with reference to the drawings.
