Abstract

In a central door-locking system for motor vehicles with actuating units arranged on the doors, the motors of the actuating units are supplied with voltage either via a first line or via a second line. In each actuating unit, the motor can be connected to the first line via a first switch and diode and to the second line via a second switch and diode. One of the switches is opened when a particular end position (locked, unlocked) is reached. The central door-locking system according to the invention is of simple construction and therefore extremely reliable. Moreover, it can be operated from a plurality of points, without faults occurring. <IMAGE>

Description

Die Erfindung bezieht sich auf eine zentrale Türverriegelungsanlage, insbesondere für Kraftfahrzeuge, mit an den Türen angeordneten elektrischen Stelleinheiten, welche eine erste und eine zweite Stellung einnehmen können. Bei bekannten zentralen Türverriegelungsanlagen wird über einen Umpolschalter die Betriebsspannung den in den Türen angeordneten Motoren zum Ver- und Entriegeln in umgekehrter Polarität zugeführt. Zum Abschalten der Motoren jeweils nach einem erfolgten Verstellvorgang ist immer ein Zeitglied, welches einen weiteren Elektromotor umfaßt und eine Umpoleinrichtung erforderlich. Derartige Türverriegelungsanlagen weisen zwar den Vorteil auf, daß zu den einzelnen Türen nur jeweils zwei Leitungen erforderlich sind und daß die Stelleinheiten nur wenig Teile aufweisen. Es ist bei derartigen Türverriegelungsanlagen jedoch schwierig, die Schaltzeitpunkte der Schalteinheit und des Wechselschalters genau auf einander abzustimmen und die Anlage in betriebsfähigen Zustand zu halten.The invention relates to a central door locking system, in particular for motor vehicles, with electrical actuating units arranged on the doors, which can assume a first and a second position. In known central door locking systems, the operating voltage is supplied to the motors arranged in the doors for locking and unlocking in reverse polarity via a pole reversal switch. To switch off the motors after each adjustment process, a timer is always required, which comprises a further electric motor and a polarity reversal device. Such door locking systems have the advantage that only two lines are required for each door and that the actuating units have only a few parts. With such door locking systems, however, it is difficult to precisely match the switching times of the switching unit and the changeover switch to one another and the system in maintain operational condition.

Bei weiteren bekannten Türverriegelungsanlagen werden die Elektromotoren nur in einer Richtung betrieben. Über ein Getriebe und einen Kurbelzapfen wird ein Schieber zwischen zwei Endlagen hin- und herbewegt. Bei diesen bekannten Türverriegelungsanlagen sind jedoch nur recht aufwendige elektrische Schaltungen bekannt geworden.In other known door locking systems, the electric motors are only operated in one direction. A slide is moved back and forth between two end positions via a gear and a crank pin. In these known door locking systems, however, only very complex electrical circuits have become known.

Aufgabe der vorliegenden Erfindung ist es, eine zentrale Türverriegelungsanlage anzugeben, bei welcher sowohl die mechanischen Teile als auch die elektrische Schaltung einfach und störunanfällig ist.The object of the present invention is to provide a central door locking system in which both the mechanical parts and the electrical circuit are simple and not susceptible to faults.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Stelleinheiten wahlweise über eine erste Leitung und über eine zweite Leitung mit dem einen Pol einer Spannungsquelle verbindbar sind; daß in jeder Stelleinheit ein Elektromotor vorgesehen ist, dessen einer Anschluß mit dem anderen Pol der Spannungsquelle und dessen anderer Anschluß über einen ersten Schalter mit der ersten Leitung und über einen zweiten Schalter mit der zweiten Leitung verbindbar ist, und daß die Schalter derart angeordnet sind, daß der erste Schalter in einer ersten Stellung eines vom Motor angetriebenen Elements offen (nichtleitend) und der zweite Schalter in einer zweiten Stellung des vom Motor angetriebenen Elements offen (nichtleitend) ist.This object is achieved according to the invention in that the actuating units can optionally be connected to the one pole of a voltage source via a first line and via a second line; that an electric motor is provided in each actuating unit, one connection of which can be connected to the other pole of the voltage source and the other connection of which can be connected to the first line via a first switch and to the second line via a second switch, and that the switches are arranged in such a way that the first switch is open (non-conductive) in a first position of a motor-driven element and the second switch is open (non-conductive) in a second position of the motor-driven element.

Die zentrale Türverriegelungsanlage gemäß der Erfindung weist den Vorteil auf, daß zur Steuerung der gesamten Anlage lediglich ein Umschalter erforderlich ist, wobei zur Steuerung der Anlage von weiteren Stellen - beispielsweise von der Beifahrertür aus - auch weitere Umschalter vorgesehen sein können. Zu den einzelnen Stellgliedern sind jeweils zwei Leitungen erforderlich und eine gemeinsame Rückführung zur Batterie.The central door locking system according to the invention has the advantage that only one switch is required to control the entire system, with the system being controlled from a distance Ren places - for example, from the passenger door - other switches can be provided. Two lines are required to the individual actuators and a common return to the battery.

Ferner weist die zentrale Türverriegelungsanlage gemäß der Erfindung den Vorteil auf, daß sich keinerlei Betriebsstörungen dadurch ergeben, daß die Motoren beispieslweise durch Exemplarstreuung oder durch unterschiedliche Betriebstemperatur verschieden schnell laufen. Es wird immer die richtige Endstellung angefahren.Furthermore, the central door locking system according to the invention has the advantage that there are no operational disruptions due to the fact that the motors run at different speeds, for example, by specimen scatter or by different operating temperatures. The correct end position is always approached.

Ein Ausführungsbeispiel der Erfindung ist in der Figur dargestellt und in der nachfolgenden Beschreibung näher erläutert.An embodiment of the invention is shown in the figure and explained in more detail in the following description.

Der Übersichtlichkeit halber wurden in der Figur lediglich drei Stelleinheiten dargestellt, obwohl eine erfindungsgemäße zentrale Türverriegelungseinrichtung beliebig viele Stelleinheiten umfassen kann. Die Stelleinheiten 1, 2 und 3 sind beispielsweise in der Fahrertür, in der Beifahrertür und in einer Fondtür eines Kraftfahrzeuges angeordnet. Sie weisen jeweils einen Motor 4, 5, 6 auf, dessen einer Anschluß mit dem Pluspol der Kraftfahrzeugbatterie verbunden ist. Die Motoren 4, 5, 6 treiben jeweils über ein nichtdargestelltes Getriebe je eine Scheibe 7, 8, 9 mit je einem Kurbelzapfen 10, 11, 12 und einem Nocken 13, 14, 15.For the sake of clarity, only three actuating units have been shown in the figure, although a central door locking device according to the invention can comprise any number of actuating units. The actuating units 1, 2 and 3 are arranged, for example, in the driver's door, in the front passenger's door and in a rear door of a motor vehicle. They each have a motor 4, 5, 6, one connection of which is connected to the positive pole of the motor vehicle battery. The motors 4, 5, 6 each drive a disk 7, 8, 9, each with a crank pin 10, 11, 12 and a cam 13, 14, 15, via a gear (not shown).

In der gezeichneten Stellung des Kurbelzapfens 10, 11, 12 öffnet der Nocken 13, 14, 15 den jeweils ersten Schalter 16, 17, 18, während der zweite Schalter 19, 20, 21 geschlossen ist.In the drawn position of the crank pin 10, 11, 12, the cam 13, 14, 15 opens the first switch 16, 17, 18, while the second switch 19, 20, 21 is closed.

In der gezeichneten Stellung verbindet der Umschalter 22, der zur zentralen Bedienung der Anlage dient, die erste Leitung 23 mit dem Minuspol 25 der Batterie. Die erste leitung 23 ist über eine erste Diode 27, 28, 29 mit dem Schalter 16, 17, 18 verbunden. Da der erste Schalter 16, 17, 18 offen ist, kann über die erste Leitung kein Strom fließen.In the position shown, the changeover switch 22, which serves for the central operation of the system, connects the first line 23 to the negative pole 25 of the battery. The first line 23 is connected to the switch 16, 17, 18 via a first diode 27, 28, 29. Since the first switch 16, 17, 18 is open, no current can flow through the first line.

Da während dieses Zustands auch über die zweite Leitung 24 kein Strom fließt - da sie nicht mit dem Minuspol verbunden ist -, erhält der Motor 4, 5, 6 keine Betriebsspannung. Die Stelleinheiten 1, 2, 3 bleiben in der dargestellten Verriegelungsstellung.Since no current flows through the second line 24 during this state - since it is not connected to the negative pole - the motor 4, 5, 6 receives no operating voltage. The actuating units 1, 2, 3 remain in the locking position shown.

Zum Entriegeln der Türen wird nun der Umschalter 22 in die untere Stellung gebracht. Der Motor 4, 5, 6 erhält Spannung über die Leitung 24, die zweite Diode 30, 31, 32 und den geschlossenen zweiten Schalter 19, 20, 21. Der Motor 4, 5, 6 läuft an und bewirkt eine Drehung der Scheibe 7, 8, 9 in Pfeilrichtung. Kurz nach dem Anlauf verläßt der Nocken 13, 14, 15 den ersten Schalter 16, 17, 18, so daß dieser geschlossen wird. Da jetzt beide Schalter geschlossen sind, läuft der Motor 4, 5, 6 unabhängig davon, in welcher Stellung sich der Umschalter 22 befindet. Für die Erläuterung des weiteren Ablaufs sei jedoch angenommen, daß sich der Umschalter 22 zumindestens dann in der unteren Stellung (Entriegelungs-Stellung) befindet, wenn der Nocken 13, 14, 15 auf den zweiten Schalter 19, 20, 21 trifft. Dann wird nämlich die Stromzufuhr zum Motor 4, 5, 6 abgeschaltet und das Stellglied 1, 2, 3 bleibt in der Entriegelungs-Stellung stehen.To unlock the doors, the switch 22 is now brought into the lower position. The motor 4, 5, 6 receives voltage via the line 24, the second diode 30, 31, 32 and the closed second switch 19, 20, 21. The motor 4, 5, 6 starts and causes the disk 7 to rotate, 8, 9 in the direction of the arrow. Shortly after startup, the cam 13, 14, 15 leaves the first switch 16, 17, 18 so that it is closed. Since both switches are now closed, the motor 4, 5, 6 runs regardless of the position in which the changeover switch 22 is. For the explanation of the further process, however, it is assumed that the changeover switch 22 is at least in the lower position (unlocking position) when the cam 13, 14, 15 meets the second switch 19, 20, 21. Then näm Lich the power to the motor 4, 5, 6 is switched off and the actuator 1, 2, 3 remains in the unlocked position.

Durch Umlegen des Umschalters 22 in die obere Stellung wird in ähnlicher Weise eine Drehung der Scheibe 7, 8, 9 um eine weitere halbe Umdrehung erreicht, womit die Türen wieder verriegelt sind.By turning the switch 22 to the upper position, a rotation of the disk 7, 8, 9 is achieved in a similar manner by a further half turn, whereby the doors are locked again.

Rechts von den schematischen Darstellungen der Stelleinheiten sind jeweils skizzenhaft zugehörige Schieber, welche in einer nicht dargestellten Führung derart geführt werden, daß sie sich nur in Pfeilrichtung bewegen können, jeweils einmal in Entriegelungs- und einmal in Verriegelungs-Stellung dargestellt. An den Schiebern 33, 34, 35 sind jeweils Mitnehmer 36, 37, 38, 39, 40, 41 derart angeordnet, daß der Kurbelzapfen 10, 11, 12 beim Durchfahren des unteren Halbkreises nach einer kurzen Leerlaufphase den Mitnehmer 36, 38, 40 und damit den Schieber 33, 34, 35 nach links schiebt. Erreicht der Kurbelzapfen 10, 11, 12 seine linke Stellung, so wird der Schalter 16, 17, 18 geöffnet und der Motor bleibt stehen. In dieser Stellung ist eine manuelle Betätigung des Schiebers 33, 34, 35 durch den jeweiligen Türsicherungsknopf möglich.To the right of the schematic representations of the actuating units are respectively sketch-like associated slides, which are guided in a guide (not shown) in such a way that they can only move in the direction of the arrow, once in the unlocking position and once in the locking position. Carriers 36, 37, 38, 39, 40, 41 are each arranged on the slides 33, 34, 35 in such a way that the crank pin 10, 11, 12, when driving through the lower semicircle, after a brief idling phase, carries 36, 38, 40 and so that the slide 33, 34, 35 pushes to the left. When the crank pin 10, 11, 12 reaches its left position, the switch 16, 17, 18 is opened and the engine stops. In this position, manual actuation of the slide 33, 34, 35 by the respective door locking button is possible.

Zum Entriegeln der Türen wird der Umschalter 22 in die untere Stellung gebracht, so daß die zweite Leitung 24 mit dem Minuspol 25 der Batterie verbunden wird. Über die Diode 30, 31, 32 und den Schalter 19, 20, 21 erhält der Motor 4, 5, 6 Strom und beginnt zu laufen. Der Kurbelzapfen 10, 11, 12 trifft dann auf den Mitnehmer 37, 39, 41 und bewegt damit den Schieber 33, 34, 35 in die Entriegelungsposition. Diese ist erreicht, wenn der Kurbelzapfen sich in der rechten gezeichneten Stellung befindet. In dieser Stellung ist der Schieber wieder manuell bedienbar. Der zweite Schalter 19, 20, 21 in jeder Stelleinheit wird geöffnet, so daß der entsprechende Motor 4, 5, 6 zum Stehen kommt.To unlock the doors, the changeover switch 22 is brought into the lower position, so that the second line 24 is connected to the negative pole 25 of the battery. The motor 4, 5, 6 receives current via the diode 30, 31, 32 and the switches 19, 20, 21 and starts to run. The crank pin 10, 11, 12 then meets the driver 37, 39, 41 and thus moves the slide 33, 34, 35 into the unlocked position. These is reached when the crank pin is in the position shown on the right. In this position the slider can be operated manually. The second switch 19, 20, 21 in each actuating unit is opened so that the corresponding motor 4, 5, 6 comes to a standstill.

Aufgrund von Exemplarstreuungen unterschiedlicher Belastung der Schlösser, Reibung, Rost im Stellglied und möglicherweise unterschiedlicher Betriebstemperaturen drehen die Motoren 4, 5 und 6 verschieden schnell. Es kann also vorkommen, daß beispielsweise die Stelleinheit 3 bereits in ihrer Endstellung ist und der Motor 5 der Stelleinheit 2 noch über beide Schalter 17, 20 mit den Leitungen 23 und 24 verbunden ist. Damit sind auch die beiden Leitungen 23 und 24 untereinander verbunden, so daß ohne zwischen geschaltete Dioden der Motor 6 über den Schalter 18 noch Spannung erhalten würde. Er würde bei der Endstellung also nicht anhalten, sondern weiterlaufen. Gegebenenfalls kann ein Diodenpaar entfallen. Dann würden die weiteren Stelleinheiten möglicherweise eine zusätzliche Umdrehung vollführen bis die Stelleinheit ohne Dioden ihre Endstellung erreicht hat.The motors 4, 5 and 6 rotate at different speeds due to the scatter of specimens of different loads on the locks, friction, rust in the actuator and possibly different operating temperatures. It can therefore happen that, for example, the actuating unit 3 is already in its end position and the motor 5 of the actuating unit 2 is still connected to the lines 23 and 24 via both switches 17, 20. So that the two lines 23 and 24 are connected to each other, so that the motor 6 would still receive voltage via the switch 18 without interposed diodes. It would not stop at the end position, but would continue to run. If necessary, a pair of diodes can be omitted. Then the further actuators would possibly make an additional revolution until the actuator without diodes has reached its end position.

Zwischen dem Umschalter 22 und dem Schieber 33, welcher in der Fahrertür angeordnet ist, ist eine gestrichelt angedeutete mechanische Verbindung 42 vorgesehen. Außerdem besteht eine Verbindung mit dem nicht dargestellten Türschloß.A mechanical connection 42, indicated by dashed lines, is provided between the changeover switch 22 and the slide 33, which is arranged in the driver's door. There is also a connection to the door lock, not shown.

Die Verbindung 42 wirkt nun derart, daß sich bei der oberen Stellung des Umschalters 22 der Schieber 33 in der linken Stellung befindet. Die Fahrertür ist somit - wie auch die anderen Türen - verriegelt.The connection 42 now acts such that the slide 33 is in the left position when the switch 22 is in the upper position. The driver's door is - like the other doors - locked.

Durch eine entsprechende Drehung des Schlüssels wird zum Entriegeln der Umschalter 22 in die untere Stellung und der Schieber 33 in die rechte Stellung gebracht. Der Entriegelungsvorgang läuft wie oben beschrieben ab. Der Schieber 33 der Fahrertür befindet sich zu Beginn der motorischen Entriegelung zwar schon in der Entriegelunsstellung, was jedoch keinen Einfluß auf den Ablauf hat.A corresponding rotation of the key brings the changeover switch 22 into the lower position and the slide 33 into the right position for unlocking. The unlocking process proceeds as described above. The slide 33 of the driver's door is already in the unlocking position at the beginning of the motorized unlocking, but this has no influence on the sequence.

Wie bei der Fahrertür kann der Stelleinheit 2 der Beifahrertür ein weiterer Umschalter 43, welcher in mechanischer Verbindung 44 mit dem Schieber 34 steht, zugeordnet sein. Das Prinzip der Erfindung läßt es zu, - falls erforderlich - alle Türen mit einem Umschalter auszurüsten, so daß von jeder Tür aus alle Türen verriegelt bzw. entriegelt werden können. Durch gleichzeitige unterschiedliche Bedienung an verschiedenen Türen treten keine Störungen auf. Die zuletzt vorgenommene Einstellung wird auf die Stelleinheiten aller Türen übertragen.As with the driver's door, a further changeover switch 43, which is mechanically connected to the slide 34, can be assigned to the actuating unit 2 of the passenger door. The principle of the invention allows, if necessary, to equip all doors with a changeover switch, so that all doors can be locked or unlocked from each door. Due to the simultaneous different operation on different doors, no faults occur. The last setting made is transferred to the actuators of all doors.
