Abstract
Description
Die Erfindung betrifft einen Scheinwerfer für Fahrzeuge, insbesondere für Kraftfahrzeuge, mit einem ellipsoidförmigen Reflektor, in dessen ersten Brennpunkt eine Lichtquelle und in dessen zweiten Brennpunkt eine Sammellinse angeordnet ist, mit einer um eine senkrecht zur optischen Achse auf einer Blendenwelle verdrehbar angeordneten Welle, die über zwei gegenüberliegende Kannten jeweils eine Hell-Dunkel-Grenze abbildet, mit Mitteln zur Betätigung und Verriegelung der Blende in den zwei gegenüberliegenden Betriebspositionen.The The invention relates to a headlamp for vehicles, in particular for motor vehicles, with an ellipsoidal Reflector, in the first focal point of a light source and in the second focal point is arranged a converging lens, with a order one perpendicular to the optical axis rotatable on a diaphragm shaft arranged wave that over two opposite ones Known each a bright-dark border maps, with means for activity and locking the shutter in the two opposite operating positions.

Aufgabe der vorliegenden Erfindung ist es, einen Scheinwerfer für Fahrzeuge derart weiterzubilden, dass eine drehbare Blende stets in eine definierte Betriebsposition bringbar ist, wobei insbesondere die ursprüngliche Betriebsposition der Blende selbsttätig und eindeutig einnehmbar ist.task The present invention is a headlamp for vehicles in such a way that a rotatable diaphragm always in a defined Operating position can be brought, in particular the original Operating position of the aperture automatically and clearly ingestible is.
Zur Lösung dieser Aufgabe ist die Erfindung in Verbindung mit dem Oberbegriff des Patentanspruchs 1 dadurch gekennzeichnet, dass das Mittel zur Betätigung und Verriegelung ein fest mit der Welle verbundenes scheibenförmiges Betätigungselement mit mindestens zwei den zwei Betriebspositionen der Blende zugeordneten Anschlägen einerseits und mindestens ein nicht mit der Welle verbundenes Rastelement umfasst, wobei dem Betätigungselement ein Federelement mit einer solchen Federspannung zugeordnet ist, derart, dass der Anschlag des Betätigungselementes stets an dem Rastelement zur Anlage kommt.To solve this problem, the invention is in connection with the preamble of the patent characterized in that the means for actuating and locking a fixedly connected to the shaft disk-shaped actuating element with at least two associated with the two operating positions of the stop stops on the one hand and at least one not connected to the shaft locking element, wherein the actuating element is a spring element with such Spring tension is assigned, such that the stop of the actuating element always comes to rest on the locking element.
Der besondere Vorteil der Erfindung besteht darin, dass die Sicherstellung einer definierten Betriebsposition der Blende gewährleistet ist. Ein Federelement bewirkt, dass ein Betätigungselement stets an einem Rastelement anliegt und somit die Blende in der vorgegebenen Betriebsposition gehalten ist. Eine solche Blendenstellung in der ursprünglichen Betriebsposition wird stets selbsttätig dann eingenommen, wenn sich die Blende in einer Drehposition befindet, in der sie nicht in einer zweiten gegenüberliegenden Betriebsposition festgelegt ist. Nach der Erfindung ist die Vorspannung des Federelementes derart gering gewählt, dass sie dazu ausreicht, das Betätigungselement mit dem Anschlag an das Rastelement zu bewegen und an demselben zu halten. Da die bei der Betätigung entgegenwirkende Federkraft relativ gering, ist der Kraftaufwand für die Verstellung der Blende relativ klein. Die Handhabung ist relativ einfach, da lediglich das Rastelement entriegelt werden muss. Nachfolgend ist der Verdrehweg des Betätigungselementes frei, so dass dieses bis zur Einnahme in eine zweite Betriebsposition verdrehbar ist, in der ein zweiter Anschlag des Betätigungselementes gegen das Rastelement drückt. Eine Änderung der Federkraft erfolgt während der Drehbewegung nicht.Of the particular advantage of the invention is that the assurance ensures a defined operating position of the diaphragm is. A spring element causes an actuating element always at one Latching element abuts and thus the aperture in the predetermined operating position is held. Such an aperture in the original Operating position is always taken automatically when the shutter is in a rotational position in which it is not in a second opposite Operating position is set. According to the invention, the bias is the spring element chosen so low that it is sufficient the actuator to move with the stop on the locking element and at the same to keep. Since the operation counteracting spring force is relatively low, is the effort for the adjustment the aperture is relatively small. The handling is relatively simple because only the locking element must be unlocked. The following is the Verdrehweg of the actuating element free, allowing this to take into a second operating position is rotatable, in a second stop of the actuating element presses against the locking element. A change the spring force occurs during not the rotation.
Nach einer Weiterbildung der Erfindung ist das Betätigungselement bzw. das Rastelement in einem Endbereich der Welle angeordnet, so dass die Betätigungs-/Verriegelungsmittel relativ platzsparend angeordnet sind.To a development of the invention is the actuating element or the latching element arranged in an end region of the shaft, so that the actuating / locking means are arranged relatively space-saving.
Nach einer Weiterbildung der Erfindung ist auf einer zu dem Betätigungselement gegenüberliegenden Seite der Welle ein Aktuator angeordnet, mittels dessen die Blende in weitere Betriebspositionen verstellbar ist. Der Aktuator ist als elektromagnetischer Rotationsaktuator ausgebildet und kann das Ver schwenken der Blende in eine Betriebsposition zweiten Typs bewirken, in der der Scheinwerfer eine Fernlichtfunktion ausübt. Bei der Verdrehung der Blendenwelle spannt sich das Federelement weiter, so dass nach Deaktivieren des Rotationsaktuators die Blende in die vorgegebene Betriebsposition ersten Typs selbsttätig zurückverschwenkt wird. Vorteilhaft kann somit das Federelement eine Doppelfunktion ausüben. Zum einen dient es zur Sicherstellung einer definierten Betriebsposition ersten Typs der Blende. Zum anderen dient es als Rückstellmittel zum selbsttätigen Zurückdrehen der Blende aus einer Betriebsposition zweiten Typs in eine ursprüngliche Betriebsposition ersten Typs.To a development of the invention is on a to the actuator opposite Side of the shaft arranged an actuator, by means of which the aperture is adjustable in further operating positions. The actuator is designed as an electromagnetic rotary actuator and can pivot the United cause the diaphragm in an operating position of the second type, in the the headlamp exerts a high beam function. At the rotation of the aperture shaft the spring element continues to stretch, so that after deactivating the Rotationsaktuators the aperture in the predetermined operating position first type automatically swiveled back becomes. Advantageously, thus, the spring element has a dual function exercise. On the one hand, it serves to ensure a defined operating position first type of aperture. On the other hand, it serves as a means of return to automatic turning back the aperture from an operating position of the second type to an original one Operating position of the first type.
Nach einer Weiterbildung der Erfindung ist das Federelement als Spiralfeder ausgebildet, die in dem als eine Betätigungsscheibe ausgebildeten Betätigungselement gelagert ist. Die Betätigungs-/Verriegelungsmittel weisen somit einen relativ einfachen und robusten sowie langzeitstabilen Aufbau auf.To a development of the invention is the spring element as a spiral spring formed in the formed as an actuating disk actuator is stored. The actuating / locking means thus have a relatively simple and robust and long-term stable Build up.
