Abstract
Description
Die vorliegende Erfindung bezieht sich auf einen Aktuator zum Verschwenken einer Scheinwerferkomponente gemäss Oberbegriff des Anspruchs 1.The The present invention relates to an actuator for pivoting a headlight component according to Preamble of claim 1.
Die Scheinwerfer von Kraftfahrzeugen werden immer mehr so ausgebildet, dass das von der Lampe erzeugte Lichtbündel verschwenkbar ist. Dadurch wird u.a. beim Fahren einer Kurve eine bessere Ausleuchtung der Fahrbahn ermöglicht. Zum Verschwenken eines Lichtbündels werden Aktuatoren mit einer Abtriebswelle verwendet, die an eine verschwenkbare Scheinwerferkomponente, z.B. einen Reflektor, ankoppelbar ist.The Headlights of motor vehicles are increasingly being designed that the light beam generated by the lamp is pivotable. Thereby is u.a. when driving a curve a better illumination of the Lane allows. For pivoting a light beam Actuators are used with an output shaft connected to a pivotable headlight component, e.g. a reflector, can be coupled is.
Zum
gesteuerten Verschwenken sind Sensoren vorzusehen, um den aktuellen
Schwenkwinkel der Abtriebswelle und somit der Scheinwerferkomponente
erfassen zu können.
Aus der
Aus der US 2004/0090788 A1 ist ein Aktuator mit einem Elektroantrieb bekannt, welcher über ein Getriebe an die Abtriebswelle gekoppelt ist und welcher drei Hallsensoren aufweist, um die Position des Rotors erfassen zu können. Der Aktuator weist dadurch einen relativ komplizierten und teuren Aufbau auf. Im Weiteren besteht auch hier das Problem, dass aufgrund eines etwaigen Spiels zwischen den Getriebegliedern die Positionen von Rotor und Abtriebswelle nicht genau in Relation zueinander stehen und daher der Schwenkwinkel der Abtriebswelle nicht genau erfassbar ist.Out US 2004/0090788 A1 is an actuator with an electric drive known which one over Gear is coupled to the output shaft and which three Hall sensors has to detect the position of the rotor can. Of the Actuator thereby has a relatively complicated and expensive construction on. Furthermore, there is also the problem that due to a any play between the gear links the positions of Rotor and output shaft are not exactly in relation to each other and therefore the swing angle of the output shaft can not be detected accurately is.

Ausgehend von diesem Stand der Technik liegt eine Aufgabe der vorliegenden Erfindung darin, einen gattungsgemässen Aktuator anzugeben, der eine präzise Messung des Schwenkwinkels der Abtriebswelle ermöglicht.outgoing from this prior art is an object of the present invention Invention is to provide a generic actuator, the one precise Measurement of the swivel angle of the output shaft allows.
Ein Aktuator, der diese Aufgabe löst, ist im Anspruch 1 angegeben. Die weiteren Ansprüche geben bevorzugte Ausführungen sowie einen Scheinwerfer mit einem erfindungsgemässen Aktuator an.One Actuator that solves this task, is specified in claim 1. The other claims give preferred embodiments and to a headlamp with an inventive actuator.
Beim erfindungsgemässen Aktuator ist ein Positionsgeber des Sensors mit einem Getriebeglied verbunden, wobei Spielreduzierungsmittel vorgesehen sind, welche ein Spiel in der Kopplung zwischen dem Getriebeglied und der Abtriebswelle reduzieren. Diese Massnahmen erlauben es, den Schwenkwinkel der Abtriebswelle präzise zu messen.At the invention Actuator is a position sensor of the sensor connected to a gear member, wherein game reduction means are provided, which is a game in the coupling between the gear member and the output shaft to reduce. These measures allow the swivel angle of the Output shaft precise to eat.

Der dargestellte Aktuator bietet u.a. folgende Vorteile:
- – Das
Vorsehen von Spielreduzierungsmitteln
28 ,29 erlaubt das Spiel in der Kopplung zwischen Getriebeglied15 und Abtriebswelle20 zu reduzieren und so mittels des Sensors30 präzise den aktuellen Schwenkwinkel der Abtriebswelle20 zu erfassen. - – Der
Sensor
30 ist beabstandet zur Abtriebswelle20 angeordnet, sodass die Sensorachse31 verschieden von der Abtriebsachse21 ist. Der Aufbau des Aktuators in Längsrichtung der Abtriebswelle20 kann dadurch kompakter gestaltet werden, insbesondere dann, wenn der Sensor30 ein Sensorgehäuse34 umfasst, in welchem der Positionsgeber32 drehbar aufgenommen ist. Im Weiteren ist der Sensor30 aufgrund der versetzten Anordnung direkt auf der Leiterplatte25 befestigbar. Dadurch können die elektrischen Leitungen zwischen Ansteuerungselektronik26 und Sensor30 kurz gehalten werden.
- - The provision of game reduction means
28 .29 allows the game in the coupling between gear member15 and output shaft20 to reduce and so by means of the sensor30 precise the current swivel angle of the output shaft20 capture. - - The sensor
30 is spaced from the output shaft20 arranged so that the sensor axis31 different from the output shaft21 is. The structure of the actuator in the longitudinal direction of the output shaft20 can be made more compact, especially if the sensor30 a sensor housing34 includes, in which the position encoder32 is received rotatably. In the following is the sensor30 due to the staggered arrangement directly on the circuit board25 fixable. This allows the electrical wires between control electronics26 and sensor30 be kept short.
Aus der vorangehenden Beschreibung sind dem Fachmann zahlreiche Abwandlungen zugänglich, ohne den Schutzbereich der Erfindung zu verlassen, der durch die Ansprüche definiert ist.Out In the foregoing description, numerous modifications will occur to those skilled in the art accessible, without departing from the scope of the invention, by the claims is defined.
