Description

Die Erfindung bezieht sich auf eine zentrale Türverriegelungsanlage, insbesondere für Kraftfahrzeuge, mit mehreren an einen Parallelschaltkreis angeschlossenen elektromotorischen Stelleinheiten, mit wenigstens einem Betriebsschalter mit einer ersten und einer zweiten Schaltstellung, über den die Stelleinheiten ansteuerbar sind und mit einem Zeitglied, durch das die Ansteuerung der Stelleinheiten unterbrechbar und eine weitere Ansteuerung vorbereitbar ist.The invention relates to a central door locking system, in particular for motor vehicles, with a plurality of electromotive actuating units connected to a parallel circuit, with at least one operating switch with a first and a second switching position, via which the actuating units can be controlled and with a timing element by which the control of the Actuators can be interrupted and a further control can be prepared.

Eine derartige Türverriegelungsanlage ist aus der DE-A-2 923 505 bekannt. Dabei ist das Zeitglied, durch das die Ansteuerung der Stelleinheiten unterbrechbar und eine weitere Ansteuerung vorbereitbar ist, eine Komponente einer Zentralelektronik.Such a door locking system is known from DE-A-2 923 505. The timing element, by means of which the actuation of the actuating units can be interrupted and a further actuation can be prepared, is a component of central electronics.

Es ist daher Aufgabe der Erfindung, eine Türverriegelungsanlage nach dem Oberbegriff zu schaffen, die bei einfachem Aufbau funktionssicher arbeitet.It is therefore an object of the invention to provide a door locking system according to the preamble which functions reliably with a simple structure.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das Zeitglied aus einem Umschalter, einem sich bei unterschiedlichen Betriebsbedingungen ähnlich den elektromotorischen Stelleinheiten verhaftenden elektromotorischen Servomotor und einem Stellelement des Servomotors besteht und dem Parallelschaltkreis der Umschalter vorgeschaltet ist, der von dem Stellelement des Servomotors jeweils nach einem Halbzyklus des Servomotors von einer mit der einen Schaltstellung des Betriebsschalters verbundenen Stellung in eine mit der zweiten Schaltstellung des Betriebsschalters verbindbaren Stellung bzw. von einer mit einem Pluspol verbundenen/nicht verbundenen Schaltstellung in eine mit dem Pluspol nicht verbundene/verbundene Schaltstellung umschaltbar ist, wobei der Servomotor dem Betriebsschalter nachgeschaltet ist und wobei jeder Betriebsschalter von einem Stellglied der ihm zugeordneten Stelleinheit so umschaltbar ist, daß alle Betriebsschalter immer die gleiche Schaltstellung einnehmen.This object is achieved in that the timing element consists of a changeover switch, an electromotive servo motor which adheres to the operating conditions similarly to the electromotive actuating units and an actuating element of the servo motor, and the parallel circuit of the changeover switch is connected upstream of the actuating element of the servo motor after every half cycle the servo motor can be switched from a position connected to the one switching position of the operating switch into a position connectable to the second switching position of the operating switch or from a switching position connected / not connected to a positive pole to a switching position not connected / connected to the positive pole, the servo motor is connected downstream of the operating switch and each operating switch can be switched over by an actuator of the actuating unit assigned to it so that all operating switches always assume the same switching position.

Es ist somit für die gesamte Türverriegelungsanlage nur ein einziger Parallelstromkreis und nur ein Zeitglied zur Ansteuerung des Stromkreises erforderlich. Ist nur ein Betriebsschalter - z. B. an der Fahrertür - vorhanden, wird an allen anderen Verriegelungsstellen jeweils nur eine Stelleinheit benötigt, die vorzugsweise ein Elektromotor ist. Es ist aber genauso möglich als Stelleinheiten Elektromagnete zu verwenden.It is therefore necessary for the entire door locking system only a single parallel circuit and only one timing element to control the circuit. Is only one operating switch - e.g. B. on the driver's door - available, only one actuator is required at all other locking points, which is preferably an electric motor. However, it is also possible to use electromagnets as control units.

Sowohl die geringe Anzahl von Bauteilen als auch die Verwendbarkeit von unempfindlichen Stelleinheiten machen die Türverriegelungsanlage störunanfällig. Gleichzeitig ermöglicht das geringe Bauvolumen eine Integration in die Stellmechanik und damit einen problemlosen Einbau in die Türen.Both the small number of components and the usability of insensitive actuators make the door locking system insensitive to faults. At the same time, the small construction volume enables integration into the actuating mechanism and thus easy installation in the doors.

Die Verwendung von Elektromotoren sowohl als Zeitglied als auch als Stelleinheiten hat den Vorteil, daß sich beide Aggregate z. B. bei Temperaturänderungen gleich verhalten. Bei Minustemperaturen reduziert sich die Drehzahl und erhöht sich die Kraft sowohl beim Zeitglied als auch bei den Stelleinheiten. Dies hat den Vorteil, daß dann, wenn durch die tiefen Temperaturen an den Türschlössern erhöhte Widerstände vorhanden sind, diese durch die Krafterhöhung an den Elektromotoren problemlos überwunden werden. Gleichzeitig paßt sich durch eine längere Laufzeit der das Zeitglied bildende Servomotor ebenfalls diesen Verhältnissen positiv an.The use of electric motors both as a timer and as actuators has the advantage that both units z. B. behave the same with temperature changes. At sub-zero temperatures, the speed is reduced and the force increases for both the timing element and the actuators. This has the advantage that if there are increased resistances due to the low temperatures on the door locks, these are easily overcome by increasing the force on the electric motors. At the same time, the servo motor forming the timing element also adapts positively to these conditions due to a longer running time.

Damit die Stellung aller Betriebsschalter der tatsächlichen Stellung der Stelleinheit angepaßt ist, ist der bzw. die Betriebsschalter von einem Stellglied der ihm zugeordneten Stelleinheit während eines Halbzyklus des Servomotors von der vor dem Halbzyklus eingenommenen Schaltstellung in seine andere Schaltstellung umschaltbar. Ein Halbzyklus ist dabei entweder durch einen Öffnungsvorgang oder durch einen Schließvorgang gegeben. Beide Vorgänge zusammen ergeben somit einen ganzen Zyklus, in dem wieder die Ausgangsstellung erreicht wird.So that the position of all operating switches is adapted to the actual position of the actuating unit, the operating switch or switches can be switched by an actuator of the actuating unit assigned to it during a half cycle of the servo motor from the switching position assumed before the half cycle to its other switching position. A half cycle is given either by an opening process or by a closing process. Both processes together result in an entire cycle in which the starting position is reached again.

Über den Betriebsschalter können die Stelleinheiten und der Servomotor mit dem Pluspol einer Stromquelle verbindbar sein.The control units and the servo motor can be connected to the positive pole of a power source via the operating switch.

Ist der Servomotor dem Umschalter nachgeschaltet im Parallelstromkreis angeordnet, so werden über nur ein Stellelement des Servomotors sowohl der Servomotor als auch die Stelleinheiten nach einem Halbzyklus ausgeschaltet.If the servo motor is arranged downstream of the changeover switch in the parallel circuit, both the servo motor and the actuating units are switched off after a half cycle via only one control element of the servo motor.

Sind durch einen Überbrückungsschalter die beiden Ausgänge des Betriebsschalters kurzschließbar, wobei der Überbrückungsschalter unmittelbar nach Beginn des Halbzyklusses des Servomotors schließbar und unmittelbar vor Ende des Halbzyklusses öffenbar, so kann es durch ein Zurückschalten des betätigten Betriebsschalters vor Ablauf eines eingeleiteten Halbzyklusses nicht zu einer Unterbrechung des Halbzyklusses kommen, der Überbrückungsschalter hält nämlich die Stromversorgung der Stelleinheiten bis zum Abschluß des Halbzyklusses aufrecht. Vorzugsweise ist der Überbrückungsschalter durch ein Stellelement des Servomotors betätigbar.If the two outputs of the operating switch can be short-circuited by a bypass switch, the bypass switch being closable immediately after the start of the half-cycle of the servo motor and opening immediately before the end of the half-cycle, then switching the actuated operating switch back before an initiated half-cycle cannot interrupt the half-cycle come, namely the bypass switch maintains the power supply to the actuators until the end of the half cycle. The bypass switch can preferably be actuated by an actuating element of the servo motor.

Sollen z. B. bei Elektromotoren als Stelleinheiten durch Drehrichtungsumkehr eine Umschaltung von einem Halbzyklus zum anderen Halbzyklus erfolgen, so kann der Umschalter ein aus zwei Einzelschaltern bestehender Doppelschalter sein, durch den der Parallelstromkreis umpolbar ist. Dabei kann je ein Eingang der Einzelschalter des Doppelschalters mit einem Minuspol verbunden sein.Should z. B. with electric motors as control units by reversing the direction of a switch from one half cycle to another half cycle, the switch can be a double switch consisting of two individual switches through which the parallel circuit can be reversed. One input each of the single switches of the double switch can be connected to a negative pole.

Eine vorteilhafte Ausbildung der Erfindung besteht darin, daß der mit einem Minuspol verbundene Servomotor über einen unmittelbar vor Ende eines Halbzyklusses umschaltbaren Wechselschalter mit dem Pluspol verbindbar ist, wobei die beiden Eingänge des mit dem Servomotor verbundenen Wechselschalters mit den beiden Ausgängen des Betriebsschalters verbunden sind. Um dabei zu vermeiden, daß nach einem eingeleiteten aber noch nicht vollendeten Halbzyklus durch Umschalten des Betriebsschalters die Stelleinheiten in einer Zwischenstellung stehen bleiben, kann der Servomotor über einen zweiten mit ihm verbundenen Wechselschalter mit dem Pluspol verbindbar sein, wobei jeweils zwei Eingänge der beiden Wechselschalter sowie die beiden Ausgänge der Wechselschalter miteinander verbunden sind, und daß aus der Ausgangsstellung in der die Wechselschalter an miteinander verbundenen Eingängen anliegen, der zweite Wechselschalter unmittelbar nach Beginn des Halbzyklusses des Servomotors umschaltbar ist. Vorzugsweise sind dabei die Wechselschalter durch ein Stellelelement des Servomotors betätigbar. Auf diese Weise wird ein eingeleiteter Halbzyklus immer auch beendet.An advantageous embodiment of the invention is that the servomotor connected to a negative pole can be connected to the positive pole via a changeover switch that can be switched immediately before the end of a half cycle, the two inputs of the with the Servo motor connected changeover switch are connected to the two outputs of the operating switch. In order to avoid that after an initiated but not yet completed half cycle by switching the operating switch, the control units remain in an intermediate position, the servo motor can be connected to the positive pole via a second changeover switch connected to it, whereby two inputs of the two changeover switches and the two outputs of the two-way switches are connected to one another, and that from the initial position in which the two-way switches are connected to inputs which are connected to one another, the second two-way switch can be switched over immediately after the start of the half-cycle of the servo motor. The changeover switches can preferably be actuated by an adjusting element of the servo motor. In this way, an initiated half cycle is always ended.

Ist im Anschluß zum Minuspol des Servomotors und/oder des Umschalters eine Thermosicherung angeordnet, so werden im Falle eines defekten Servomotors Schäden an der Türverriegelungsanlage vermieden.If a thermal fuse is arranged in connection to the negative pole of the servo motor and / or the changeover switch, damage to the door locking system is avoided in the event of a defective servo motor.

Die in den Figuren dargestellten Türverriegelungsanlagen weisen vier Einheiten auf. Eine Fahrertüreinheit 1, eine Beifahrertüreinheit 2, eine Rücksitztüreinheit 3 und eine Tankdeckeleinheit 4. Dabei sind die Rücksitztüreinheit 3 und die Tankdeckeleinheit 4 gleich.The door locking systems shown in the figures have four units. A driver's door unit 1, a passenger's door unit 2, a rear seat door unit 3 and a fuel cap unit 4. The rear seat door unit 3 and the fuel cap unit 4 are the same.

Die Stelleinheiten 5 der vier Einheiten 1 bis 4 sind an einen Parallelschaltkreis 6 angeschlossene Elektromotoren. Dem Parallelschaltkreis 6 ist ein Doppelumschalter 7 bzw. 7' vorgeschaltet, durch den der Parallelschaltkreis 6 umpolbar ist. Betätigt wird der Doppelumschalter 7 bzw. 7' durch einen Servomotor 8 bzw. 8'. Der Doppelumschalter 7 bzw. 7' besteht aus zwei Einzelschaltern, von denen je ein Eingang mit einem Minuspol 9 verbunden und je ein Eingang mit einem Pluspol 10 verbunden bzw. verbindbar ist.The actuating units 5 of the four units 1 to 4 are electric motors connected to a parallel circuit 6. A double changeover switch 7 or 7 ′ is connected upstream of the parallel circuit 6, by means of which the parallel circuit 6 can be reversed. The double changeover switch 7 or 7 'is actuated by a servo motor 8 or 8'. The double changeover switch 7 or 7 'consists of two single switches, of which one input is connected to a negative pole 9 and one input is connected or connectable to a positive pole 10.

Weiterhin besitzen die Fahrertüreinheit 1 und die Beifahrertüreinheit 2 einen mit einem Stellknopf 12 versehenen Betriebsschalter 11, über den der Pluspol 10 mit dem Servomotor 8 bzw. 8' verbindbar ist.Furthermore, the driver's door unit 1 and the passenger's door unit 2 have an operating switch 11 provided with an adjusting button 12, via which the positive pole 10 can be connected to the servo motor 8 or 8 '.

In Figur 1 ist der Servomotor 8 dem Doppelumschalter 7 nachgeschaltet im Parallelstromkreis 6 angeordnet. Je ein Ausgang der Betriebsschalter 11 ist mit einem Eingang jedes Einzelschalters des Doppelumschalters 7 verbunden. Die Schaltbrücken 13, 13' der Einzelschalter sind derart miteinander gekoppelt, daß sie als stabiler Schalter zusammen umschaltbar und immer nur mit an einem entgegengesetzten Pol verbindbaren Eingang anlegbar sind. Dadurch kommt es beim Umschalten des Doppelumschalters 7 zu einem Umpolen des Parallelschaltkreises 6 und einer Drehrichtungsumkehr des Servomotors 8 und der Stelleinheiten 5.In Figure 1, the servo motor 8 is arranged downstream of the double changeover switch 7 in the parallel circuit 6. One output each of the operating switches 11 is connected to an input of each individual switch of the double changeover switch 7. The switching bridges 13, 13 'of the individual switches are coupled to one another in such a way that they can be switched together as a stable switch and can only be applied with an input which can be connected to an opposite pole. This results in a reversal of the polarity of the parallel circuit 6 and a reversal of the direction of rotation of the servo motor 8 and the actuating units 5 when the double changeover switch 7 is switched over.

Ein solches Umschalten des Doppelumschalters 7 erfolgt über ein Stellelement 14 des Servomotors 8, wenn dieser nach einer Ansteuerung einen Halbzyklus durchgeführt hat. Innerhalb eines solchen Halbzyklusses wird entweder ein Verriegelungs-oder ein Entriegelungsvorgang an den Stelleinheiten 5 durchgeführt. Jeder Betriebsschalter 11 ist über ein Stellelement 15 von der ihm zugeordneten Stelleinheit 5 so umschaltbar, daß alle Betriebsschalter 11 immer die gleiche Schaltstellung einnehmen.Such a switchover of the double changeover switch 7 takes place via an actuating element 14 of the servo motor 8 if the latter has carried out a half cycle after activation. Either a locking or an unlocking process is carried out on the actuating units 5 within such a half cycle. Each operating switch 11 can be switched over by an actuating element 15 from the actuating unit 5 assigned to it so that all operating switches 11 always assume the same switching position.

Die Türverriegelungsanlage in Figur 2 entspricht der Anlage in Figur 1. Zusätzlich ist noch ein Überbrückungsschalter 16 vorhanden, durch den die beiden Ausgänge des Betriebsschalters miteinander verbindbar sind. Über ein Stellelement 17 des Servomotors 8 wird der Überbrückungsschalter 16 derart betätigt, daß er aus der geöffneten Grundstellung unmittelbar nach Beginn eines Halbzyklusses schließt und unmittelbar vor Ende des Halbzyklusses öffnet. Dadurch ist es nicht möglich, daß der Servomotor 8 und die Stelleinheiten 5 in einer Zwischenstellung stehen bleiben, wenn der Betriebsschalter 11 sofort nach dem Einleiten eines Ver- bzw. Entriegelungsvorganges vor Abschluß des Halbzyklusses wieder zurückgeschaltet wird.The door locking system in FIG. 2 corresponds to the system in FIG. 1. In addition, a bridging switch 16 is also present, by means of which the two outputs of the operating switch can be connected to one another. Via a control element 17 of the servo motor 8, the bypass switch 16 is actuated in such a way that it closes from the open basic position immediately after the beginning of a half cycle and opens immediately before the end of the half cycle. As a result, it is not possible for the servo motor 8 and the actuating units 5 to remain in an intermediate position if the operating switch 11 is switched back again immediately after initiating a locking or unlocking process before the end of the half cycle.

In Figur 3 entspricht der als Tastschalter ausgebildete Doppelumschalter 7 und der Anschluß seiner Eingänge dem aus den Figuren 1 und 2. Ebenfalls die Betriebsschalter 11 sind auf die gleiche Weise über Stellelemente 15 durch die jeweils zugeordneten Stelleinheiten umschaltbar.In FIG. 3, the double changeover switch 7 in the form of a pushbutton switch and the connection of its inputs correspond to that in FIGS. 1 and 2. Likewise, the operating switches 11 can be switched over in the same way via control elements 15 by the respectively assigned control units.

Der mit dem Minuspol 9 direkt verbundene Servomotor 8' ist sowohl über einen ersten als auch einen zweiten Wechselschalter 18 und 19 mit je einem Ausgang des Betriebsschalters 11 verbindbar. Dabei ist jeweils ein Eingang jedes Wechselschalters 18 und 19 mit dem einen Ausgang des Betriebsschalters 11 und jeweils der zweite Eingang jedes Wechselschalters 18 und 19 mit dem zweiten Ausgang des Betriebsschalters 11 verbunden. Die Ausgänge der Wechselschalter 18 und 19 sind gemeinsam zum Servomotor 8' geführt. Die Wechselschalter 18 und 19 sind über Stellelemente 20 und 21 derart vom Servomotor 8' aus einer mit dem gleichen Ausgang des Betriebsschalters 11 verbundenen Ausgangsstellung umschaltbar, daß der Wechselschalter 18 unmittelbar vor dem Ende eines Halbzyklusses und der Wechselschalter 19 unmittelbar nach Beginn des Halbzyklusses des Servomotors 8' umschalten. Auf diese Weise können der Servomotor 8' sowie die Stelleinheiten 5 nicht durch sofortiges Zurückschalten des betätigten Betriebsschalters 11 in einer Zwischenposition stehenbleiben, sondern beenden immer einen angefangenen Halbzyklus.The servo motor 8 ′ which is directly connected to the negative pole 9 can be connected to an output of the operating switch 11 both via a first and a second changeover switch 18 and 19. One input of each changeover switch 18 and 19 is connected to the one output of the operating switch 11 and the second input of each changeover switch 18 and 19 is connected to the second output of the operating switch 11. The outputs of the changeover switches 18 and 19 are routed together to the servo motor 8 '. The changeover switches 18 and 19 are of the same type via servo elements 8 and 21 from the servo motor 8 ' Output of the operating switch 11 connected starting position switchable, that the changeover switch 18 switch immediately before the end of a half cycle and the changeover switch 19 immediately after the start of the half cycle of the servo motor 8 '. In this way, the servo motor 8 'and the actuating units 5 cannot stop in an intermediate position by immediately switching the actuated operating switch 11 back, but always end a half cycle that has started.

Das Ausführungsbeispiel in Figur 4 besitzt die gleiche Anordnung von Wechselschaltern 18 und 19 wie das Beispiel in Figur 3. Diese Wechselschalter 18 und 19 werden auch auf die gleiche Weise durch Stellelemente 20 und 21 vom Servomotor 8' umgeschaltet wie in Figur 3.The exemplary embodiment in FIG. 4 has the same arrangement of change-over switches 18 and 19 as the example in FIG. 3. These change-over switches 18 and 19 are also switched over by the servo motor 8 ′ in the same way by adjusting elements 20 and 21 as in FIG. 3.
