Description
Stand der Technik State of the art
Die Erfindung betrifft eine Einrichtung zur Erfassung der Winkellage einer Welle eines Scheibenwischermotors nach dem Oberbegriff des Anspruchs 1. Ferner betrifft die Erfindung einen Scheibenwischermotor unter Verwendung einer erfindungsgemäßen Einrichtung. The invention relates to a device for detecting the angular position of a shaft of a windscreen wiper motor according to the preamble of claim 1. Furthermore, the invention relates to a windscreen wiper motor using a device according to the invention.
Eine Einrichtung nach dem Oberbegriff des Anspruchs 1 ist aus der Praxis bekannt und dient dazu, die genaue Position einer Antriebswelle eines Scheibenwischermotors zu erfassen, damit dieser durch eine Steuereinrichtung des Scheibenwischermotors derart angesteuert werden kann, dass die in Wirkverbindung mit dem Scheibenwischermotor angeordneten Wischblätter einer Scheibenwischeinrichtung beispielsweise zu einem bestimmten Zeitpunkt gestoppt werden können. Die aus dem Stand der Technik bekannten Einrichtungen verwenden hierzu Hall-Sensoren, die das Magnetfeld eines an der Welle des Elektromotors angeordneten Magnetelements erfassen. Die Hall-Sensoren sind dabei in unterschiedlichen radialen Positionen an die Welle des Elektromotors angeordnet, sodass aus der Kombination der von Hall-Sensoren erfassten Signale auf eine bestimmte Winkelstellung der Welle geschlossen werden kann. Die Hall-Sensoren sind jeweils als separate Bauteile ausgebildet und über entsprechende elektrische Verbindungsleitungen mit einer Steuereinrichtung bzw. einer Auswerteschaltung verbunden, die auf einer Leiterplatte angeordnet ist, die innerhalb des Scheibenwischermotors angeordnet ist und der Steuerung des Scheibenwischermotors dient. A device according to the preamble of claim 1 is known from practice and serves to detect the exact position of a drive shaft of a windshield wiper motor, so that it can be controlled by a control device of the windshield wiper motor such that arranged in operative connection with the windshield wiper motor wiper blades of a windshield wiper device for example, can be stopped at a certain time. For this purpose, the devices known from the prior art use Hall sensors which detect the magnetic field of a magnetic element arranged on the shaft of the electric motor. The Hall sensors are arranged in different radial positions on the shaft of the electric motor, so that from the combination of the signals detected by Hall sensors can be concluded that a certain angular position of the shaft. The Hall sensors are each formed as separate components and connected via corresponding electrical connection lines with a control device or an evaluation circuit which is arranged on a printed circuit board, which is arranged within the windscreen wiper motor and serves to control the windscreen wiper motor.

Offenbarung der Erfindung Disclosure of the invention
Ausgehend von dem dargestellten Stand der Technik liegt der Erfindung die Aufgabe zugrunde, eine Einrichtung zur Erfassung der Winkellage einer Welle eines Scheibenwischermotors nach dem Oberbegriff des Anspruchs 1 derart weiterzubilden, dass hinsichtlich der verwendeten Magnetfeldsensoren ein vereinfachter Aufbau bzw. ein geringerer Raumbedarf ermöglicht wird. Diese Aufgabe wird erfindungsgemäß bei einer Einrichtung mit den Merkmalen des Anspruchs 1 dadurch gelöst, dass die Magnetfeldsensoranordnung einen einzigen Magnetfeldsensor in Form eines Magnetowiderstandssensors umfasst. Es werden damit die aus dem Stand der Technik bei Scheibenwischermotoren bekannten mehreren Hall-Sensoren bzw. SMD-Bauteile durch einen einzigen Magnetfeldsensor ersetzt, der als absolut messender Winkelsensor die Winkellage der Welle des Scheibenwischermotors erfasst. Derartige Magnetowiderstandssensoren sind beispielsweise in sogenannter AMR-Technologie oder in GMR-Technologie aus dem Stand der Technik bekannt. Unter der AMR-Technologie versteht man dabei eine Technologie, die sich den anisotropen Magnetowiderstandseffekt zunutze macht, um Veränderungen des Magnetfelds zu erfassen und auszuwerten. Bei dem GMR-Effekt handelt es sich dabei um den sogenannten Riesen-Magnetowiderstandseffekt. Derartige Magnetowiderstandssensoren haben den Vorteil, dass sie eine relativ hohe Genauigkeit bzw. hohe Auflösung ermöglichen, sehr robust bzw. unempfindlich gegen hohe oder niedrige Temperaturen, Verschmutzung, Strahlung, mechanische Belastung durch Stöße oder Vibrationen sind und eine hohe Empfindlichkeit aufweisen. Based on the illustrated prior art, the invention has the object, a device for detecting the angular position of a shaft of a windscreen wiper motor according to the preamble of claim 1 such that with respect to the magnetic field sensors used a simplified structure and a smaller space requirement is possible. This object is achieved in a device with the features of claim 1, characterized in that the magnetic field sensor arrangement comprises a single magnetic field sensor in the form of a magnetoresistive sensor. Thus, the multiple Hall sensors or SMD components known from the prior art in windscreen wiper motors are replaced by a single magnetic field sensor, which detects the angular position of the shaft of the windscreen wiper motor as the absolute measuring angle sensor. Such magnetoresistive sensors are known, for example, in so-called AMR technology or in GMR technology from the prior art. AMR technology is a technology that makes use of the anisotropic magnetoresistance effect to detect and evaluate changes in the magnetic field. The GMR effect is the so-called giant magnetoresistance effect. Such magnetoresistive sensors have the advantage that they allow a relatively high accuracy or high resolution, are very robust or insensitive to high or low temperatures, pollution, radiation, mechanical stress due to shocks or vibrations and have a high sensitivity.
Vorteilhafte Weiterbildungen der erfindungsgemäßen Einrichtung zur Erfassung der Winkellage einer Welle eines Scheibenwischermotors sind in den Unteransprüchen aufgeführt. In den Rahmen der Erfindung fallen sämtliche Kombinationen aus zumindest zwei von in den Ansprüchen, der Beschreibung und/oder den Figuren offenbarten Merkmalen. Advantageous developments of the device according to the invention for detecting the angular position of a shaft of a windscreen wiper motor are listed in the subclaims. All combinations of at least two of the features disclosed in the claims, the description and / or the figures fall within the scope of the invention.
Besonders bevorzugt ist eine Anordnung des Magnetfeldsensors auf einer Leiterplatte, die gleichzeitig der Aufnahme der elektrischen bzw. elektronischen Bauteile zur Steuerung des Scheibenwischermotors dient. Dadurch wird keine separate Leiterplatte bzw. kein separates Trägerelement für den Magnetfeldsensor benötigt, der dann über geeignete Verbindungsleitungen mit der Leiterplatte verbunden werden muss, die der Steuerung des Scheibenwischermotors dient. Neben den dadurch reduzierten Herstellkosten wird darüber hinaus durch den Verzicht auf das zusätzliche Trägerelement auch ein besonders kompakter Aufbau des Scheibenwischermotors in dem relevanten Bereich ermöglicht. Particularly preferred is an arrangement of the magnetic field sensor on a printed circuit board, which also serves to receive the electrical or electronic components for controlling the windscreen wiper motor. As a result, no separate circuit board or a separate support member for the magnetic field sensor is needed, which must then be connected via suitable connecting lines to the circuit board, which serves to control the windshield wiper motor. In addition to the resulting reduced manufacturing costs is also made possible by dispensing with the additional support member and a particularly compact design of the windshield wiper motor in the relevant area.
Da die (Anker-)Welle des Scheibenwischermotors üblicherweise im Bereich ihrer beiden Stirnseiten in Lagerelementen gelagert ist, würde eine Anordnung des Magnetelements an einer Stirnseite der (Anker-)Welle des Scheibenwischermotors dessen Baugröße in axialer Erstreckung vergrößern. Daher ist es bevorzugt vorgesehen, dass das Magnetelement die (Anker-)Welle an ihrem Umfang umfasst. Since the (armature) shaft of the windshield wiper motor is usually mounted in the region of its two end faces in bearing elements, an arrangement of the magnetic element at an end face of the (armature) shaft of the windshield wiper motor would increase its size in the axial extent. Therefore, it is preferably provided that the magnetic element comprises the (armature) shaft at its periphery.
Ganz besonders bevorzugt ist es, wenn das Magnetelement im Bereich eines Getriebegehäuses des Scheibenwischermotors angeordnet ist. Dies erfolgt vor dem Hintergrund, dass die Leiterplatte zur Steuerung des Scheibenwischermotors ebenfalls im Getriebegehäuse angeordnet ist, da dort, im Vergleich zum Motorgehäuse, infolge des üblicherweise vorhandenen Getrieberades und der geometrischen Verhältnisse mehr Bauraum zur Unterbringung einer Leiterplatte zur Verfügung steht als im Bereich des Motorgehäuses. It is very particularly preferred if the magnetic element is arranged in the region of a transmission housing of the windscreen wiper motor. This is done against the background that the circuit board for controlling the windshield wiper motor also in Gearbox is arranged because there, compared to the motor housing, due to the usually existing gear and the geometric conditions more space to accommodate a circuit board is available as in the range of the motor housing.
Ganz besonders bevorzugt ist es, wenn das wenigstens eine Magnetelement bei einer Anordnung im Getriebegehäuse zwischen einem Motorgehäusebereich und einem Getrieberad angeordnet ist. In diesem Bereich steht üblicherweise der meiste Bauraum zur Unterbringung von Zusatzelementen bzw. für die Leiterplatte zur Verfügung. It is particularly preferred if the at least one magnetic element is arranged in an arrangement in the gear housing between a motor housing portion and a gear wheel. In this area, most of the space is usually available for accommodating additional elements or for the printed circuit board.
Bevorzugt ist weiterhin der Einsatz der erfindungsgemäßen Einrichtung bei einem bürstenlosen Scheibenwischermotor. Bei einem derartigen bürstenlosen Scheibenwischermotor ist es zur korrekten Ansteuerung der einzelnen Wicklungen erforderlich, diese in Abhängigkeit von der Winkellage der Ankerwelle zu bestromen bzw. anzusteuern. Die Einrichtung dient somit nicht nur dazu, den Scheibenwischermotor bei einer bestimmten Winkelstellung zu stoppen bzw. zu starten, um die mit dem Scheibenwischermotor wirkverbundenen Scheibenwischer hin- und herzubewegen, sondern sie ist dazu erforderlich, den Scheibenwischermotor überhaupt betreiben zu können. Preference is also the use of the device according to the invention in a brushless windscreen wiper motor. In such a brushless windscreen wiper motor, it is necessary for the correct control of the individual windings to energize or drive them as a function of the angular position of the armature shaft. Thus, the device not only serves to stop or start the wiper motor at a certain angular position to reciprocate the windshield wipers operatively connected to the wiper motor, but is required to operate the wiper motor at all.
In konstruktiv bevorzugter Anordnung des Magnetfeldsensors wird vorgeschlagen, dass dieser auf der der Welle zugewandten Seite der Leiterplatte angeordnet ist, wobei die Ebene der Leiterplatte parallel zur Längsachse der Welle verläuft. Dadurch wird ein besonders kompakter Aufbau der Einrichtung erzielt und die Erfassung des an dem Magnetfeldsensor sich vorbeibewegenden Magnetfeldes des Magnetelements wird vereinfacht. In a structurally preferred arrangement of the magnetic field sensor is proposed that this is arranged on the side facing the shaft of the circuit board, wherein the plane of the circuit board is parallel to the longitudinal axis of the shaft. As a result, a particularly compact construction of the device is achieved and the detection of the magnetic field sensor moving past the magnetic field of the magnetic element is simplified.
Die Erfindung umfasst auch einen Scheibenwischermotor mit einer erfindungsgemäßen Einrichtung. Ein derartiger Scheibenwischermotor ermöglicht eine besonders kompakte Einrichtung zur Erfassung der Winkellage der Welle durch die Verwendung lediglich eines einzigen Magnetfeldsensors in Form eines Magnetowiderstandssensors. The invention also includes a windscreen wiper motor with a device according to the invention. Such a windscreen wiper motor enables a particularly compact device for detecting the angular position of the shaft by using only a single magnetic field sensor in the form of a magnetoresistive sensor.
