Description

Die Erfindung bezieht sich auf eine zentrale Türverriegelungsanlage insbesondere für Kraftfahrzeuge, mit an einen Parallelschaltkreis angeschlossenen elektrischen Stelleinheiten, wobei der Parallelschaltkreis durch eine Schalteinheit umpolbar mit einer Stromquelle verbindbar ist, und mit einem elektromotorischen Zeitglied zur Steuerung der Schalteinheit, das Ober einen manuell betätigbaren Betriebsschalter und einen mit diesem in Reihe geschalteten Wechselschalter mit einer Stromquelle verbindbar ist, wobei der Wechselschalter nach einem halben Stellzyklus durch das Zeitglied in eine den Stromfluß unterbrechende, eine Ansteuerung eines zweiten halben Stellzyklusses vorbereitende Stellung umschaltbar ist.The invention relates to a central door locking system, in particular for motor vehicles, with electrical actuating units connected to a parallel circuit, the parallel circuit being connectable to a power source by means of a switching unit, and with an electromotive timing element for controlling the switching unit, the upper part having a manually operated operating switch and a toggle switch connected in series with this can be connected to a current source, the toggle switch being switchable after half a setting cycle by the timing element into a position which interrupts the current flow and prepares for actuation of a second half setting cycle.

Bei einer derartigen Türverriegelungsanlage besteht das Problem, daß die Schaltzeitpunkte der Schalteinheit und des Wechselschalters äußerst genau aufeinander abgestimmt sein müssen, um die Anlage in betriebsfähigem Zustand zu halten. Dies ist besonders schwierig, da das elektromotorische Zeitglied zu einem Nachlaufen nach einem Abschalten der Stromversorgung neigt.In such a door locking system, there is the problem that the switching times of the switching unit and the changeover switch must be matched to one another extremely precisely in order to keep the system in an operational state. This is particularly difficult because the electromotive timer tends to run after the power supply is switched off.

Darüber hinaus sind aufwendige zusätzliche Schaltungen erforderlich um zu vermeiden, daß die Stelleinheiten in einer Zwischenstellung zwischen den beiden Endstellungen stehen bleiben, wenn der Betriebsschalter sofort nach dem Einleiten eines Verriegelungsvorganges wieder zurückgeschaltet wird.In addition, complex additional circuits are required in order to avoid that the actuating units remain in an intermediate position between the two end positions if the operating switch is switched back immediately after the initiation of a locking process.

Es ist daher Aufgabe der Erfindung, eine Türverriegelungsvorrichtung nach dem Oberbegriff zu schaffen, die bei einfachem Aufbau eine zuverlässige Funktion gewährleistet.It is therefore an object of the invention to provide a door locking device according to the preamble, which ensures reliable operation with a simple structure.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß dem Beginn einer Bestromung des Zeitglieds nacheilend der Parallelschaltkreis mit der Stromquelle verbindbar ist und der Wechselschalter einer änschließenden Trennung des Parallelschaltkreises von der Stromquelle voreilend umschaltbar ist, wobei das Zeitglied mit dem Parallelschaltkreis verbunden ist. Durch diese erfindungsgemäße Ausbildung kommt es in einanderüberlappender Weise zuerst zu einer Stromversorgung des Zeitglieds über den Betriebsschalter und anschließend über den Parallelschaltkreis. Der Wechselschalter kann dadurch ohne Schaltpunktprobleme durch das ihm nachgeordnete Zeitglied umgeschaltet und damit die Stromversorgung über den Betriebsschalter unterbrochen werden. Trotzdem setzt das Zeitglied bis zum Abschluß seines halben Stellzyklusses seine Funktion bis zur Umsteuerung der Schalteinheit fort.This object is achieved in that the parallel circuit can be connected to the current source after the start of energization of the timing element and the changeover switch of a subsequent separation of the parallel circuit from the current source can be switched over prematurely, the timing element being connected to the parallel circuit. This configuration according to the invention results in an overlapping manner first of all that the timer is supplied with power via the operating switch and then via the parallel circuit. The changeover switch can thus be switched over by the timer arranged downstream of it without switching point problems and the power supply can thus be interrupted via the operating switch. Nevertheless, the timer continues its function until the switching unit is reversed until the end of its half actuating cycle.

Da nach dem Anschließen des Parallelschaltkreises an die Stromquelle, was kurz nach dem Anlaufen des Zeitglieds erfolgt, das Zeitglied zweifach mit einer Stromquelle verbunden ist, wird bei Zurückschalten des Betriebsschalters vor Abschluß eines Schließvorganges dieser trotzdem durch die Stromversorgung des Zeitglieds über den Parallelschaltkreis bis zu Ende durchgeführt. Dadurch ermöglicht die erfindungsgemäße Ausbildung auch eine einwandfrei funktionsfähige mehrere Stelleinheiten aufweisende Türverriegelungsanlage mit nur einem einzigen Betriebsschalter.Since after connecting the parallel circuit to the power source, which occurs shortly after the timer has started up, the timer is connected twice to a power source, when the operating switch is switched back before a closing operation is completed, the latter is nevertheless powered by the power supply of the timer via the parallel circuit to the end carried out. As a result, the design according to the invention also enables a perfectly functional, multiple actuating unit door locking system with only a single operating switch.

Die Stromversorgung des Zeitglieds über den Parallelschaltkreis erfolgt auf einfache Weise dadurch, daß jeder Strang des Parallelschaltkreises über einen Stromfluß vom Zeitglied zur Parallelschaltung sperrende Dioden mit dem Zeitglied verbunden ist. Dabei verhindern die Dioden zum einen eine Bestromung des Parallelschaltkreises über den Betriebsschalter und zum anderen einen Kurzschluß zwischen den beiden Strängen des Parallelschaltkreises.The power supply of the timer via the parallel circuit is carried out in a simple manner in that each strand of the parallel circuit is connected to the timer by a current flow from the timer to the parallel circuit blocking diodes. The diodes on the one hand prevent the parallel circuit from being energized via the operating switch and on the other hand prevent a short circuit between the two strands of the parallel circuit.

Um eine Beeinflussung des Betriebsschalters von dem Stromfluß des Parallelschaltkreises zu vermeiden, kann zwischen dem Betriebsschalter und den Verbindungen des Parallelschaltkreises mit dem Zeitglied eine einen Stromfluß vom Zeitglied zum Betriebsschalter sperrende Diode angeordnet sein.In order to prevent the operating switch from being influenced by the current flow of the parallel circuit, a diode blocking a flow of current from the timing element to the operating switch can be arranged between the operating switch and the connections of the parallel circuit to the timing element.

Einen einfachen Aufbau der Schalteinheit erreicht man dadurch, daß die Schalteinheit je einem Strang des Parallelschaltkreises zugeordnet einen Einzelschalter aufweist, durch den der jeweilige Strang mit einem Minuspol bzw. einem Pluspol der Stromquelle verbindbar ist. Dabei sind vorzugsweise die Einzelschalter in Ruhestellung der Anlage mit dem Minuspol verbunden.A simple construction of the switching unit is achieved in that the switching unit has a single switch assigned to each branch of the parallel circuit, through which the respective branch can be connected to a negative pole or a positive pole of the current source. The individual switches are preferably connected to the negative pole in the rest position of the system.

Der Wechselschalter und/oder die Schalteinheit können über z.B. als Nocken einer Nockensteuerung ausgebildete Stellglieder des Zeitglieds steuerbar sein.The changeover switch and / or the switching unit can be e.g. Actuators of the timing element designed as cams of a cam control can be controlled.

Zu einer geringen Baugröße und wenigen einfachen Bauteilen führt es, wenn die Nocken drehbar antreibbare Nockenscheiben sind, an denen Schalttaster des Wechselschalters und/oder der Schalteinheit in Anlage sind, wobei die dem Wechselschalter zugeordnete Nockenscheibe und die beiden Einzelschaltern der Schalteinheit gemeinsam zugeordnete Nockenscheibe miteinander drehfest verbunden sein können.A small size and a few simple components result when the cams are rotatably drivable cam disks on which switch buttons of the two-way switch and / or the switching unit are in contact, the cam disk assigned to the two-way switch and the two individual switches of the switching unit jointly assigned to each other in a rotationally fixed manner can be connected.

Die Nockenscheibe ist vorzugsweise während eines Stellzyklusses um 360° verdrehbar.The cam disk can preferably be rotated through 360 ° during an actuating cycle.

Besitzt die den um 180° zueinander versetzt angeordneten Einzelschaltern zugeordnete Nockenscheibe zwei Umschaltpunkte, die um einen um einen Winkel a kleineren Winkel als 180° zueinander versetzt zwischen den beiden Einzelschaltern mit in Ruhestellung gleichem geringem Abstand zu den Einzelschaltern angeordnet sind, wobei der Winkel a etwas größer ist als der maximal mögliche Nachlauf, so führt selbst ein Nachlaufen des elektromotorischen Zeitglieds nicht zu einem erneuten Bestromen des Parallelschaltkreises.The cam disk assigned to the individual switches offset from one another by 180 ° has two switching points which are offset by an angle smaller than 180 ° from one another between the two individual switches with the same distance from the individual switches in the rest position, the angle a being somewhat is greater than the maximum possible run-on, even a run-on of the electromotive timing element does not lead to renewed current supply to the parallel circuit.

Besitzt die dem Wechselschalter zugeordnete Nockenscheibe zwei um 180° zueinander versetzte Umschaltpunkte, wobei sich der Wechselschälter in der Ruhelage der Anlage in einer gegenüber einem Schaltpunkt in Bewegungsrichtung der Nockenscheibe um einen Winkel zurückversetzten Lage befindet, so ist nach einem halben Stellzyklus der Wechselschalter gerade umgeschaltet, um die Schaltung für den nächsten halben Stellzyklus vorzubereiten. Ist dabei der Winkel größer als zwei a, so ist sichergestellt, daß bei jedem unterschiedlichen Nachlauf des Zeitglieds innerhalb des maximal zulässigen Nachlaufs ein Umschalten des Wechselschalters erfolgt.The cam disk assigned to the changeover switch has two changeover points offset by 180 ° with respect to one another, the changeover switch in the rest position of the system facing one another a switching point in the direction of movement of the cam disc is set back by an angle, the changeover switch has just been switched after half a setting cycle in order to prepare the switching for the next half setting cycle. If the angle is greater than two a, it is ensured that the changeover switch is switched over for each different run-on of the timing element within the maximum permissible run-on.

Ohne zusätzliche aufwendige Schaltungen können mit dem Wechselschälter mehrere manuell betätigbare Betriebsschalter in Reihe geschaltet sein, so daß z.B. jeder Tür ein Betriebsschalter zugeordnet ist.Without additional complex circuits, several manually operated operating switches can be connected in series with the changeover switch, so that e.g. an operating switch is assigned to each door.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben. Es zeigen

An embodiment of the invention is shown in the drawing and will be described in more detail below. Show it
  • Figure 1 is a circuit diagram of a door locking system
  • Figure 2 shows a cam disc control with individual switches of the switching unit and a changeover switch

Ober einen ersten Betriebsschalter 1 und/oder einen zweiten Betriebsschalter 2 ist der Pluspol 3 einer Stromquelle manuell entweder mit einem ersten Strang 4 oder einem zweiten Strang 5 verbindbar. Der Strang 4 führt zu einem ersten Eingang 6 und der Strang 5 zu einem zweiten Eingang 7 eines Wechselschalters 8.Via a first operating switch 1 and / or a second operating switch 2, the positive pole 3 of a current source can be connected manually to either a first line 4 or a second line 5. The strand 4 leads to a first input 6 and the strand 5 to a second input 7 of a changeover switch 8.

Der Ausgang 9 des Wechselschalters 8 ist über eine Diode 10 mit einem ein Zeitglied bildenden Servomotor 11 verbunden, der wiederum mit einem Minuspol 12 in Verbindung steht.The output 9 of the changeover switch 8 is connected via a diode 10 to a servo motor 11 forming a timing element, which in turn is connected to a negative pole 12.

Eine Schalteinheit 13 besteht aus zwei Einzelschaltern 14 und 15, die in der Ruhestellung der Anlage beide an einem mit dem Minuspol 12 verbundenen Eingang 16 bzw. 17 in Anlage sind. Die beiden anderen Eingänge 16 und 19 der Einzelschalter 14 und 15 stehen mit einem Pluspol 20 der Stromquelle in Verbindung.A switching unit 13 consists of two individual switches 14 and 15, both of which are in contact with an input 16 and 17 connected to the negative pole 12 in the rest position of the system. The two other inputs 16 and 19 of the individual switches 14 and 15 are connected to a positive pole 20 of the current source.

Die Ausgänge der Einzelschalter 14 und 15 führen je zu einem Strang 21 und 22 eines parallelen Schaltkreises an den zwei elektrische Stelleinheiten 23 angeschlossen sind.The outputs of the individual switches 14 and 15 each lead to a line 21 and 22 of a parallel circuit to which two electrical actuating units 23 are connected.

Der Strang 21 ist über eine Diode 24 und der Strang 22 über eine Diode 25 mit dem Eingang des Servomotors 11 verbunden, der mit dem Wechselschalter 8 in Verbindung steht.The strand 21 is connected via a diode 24 and the strand 22 via a diode 25 to the input of the servo motor 11, which is connected to the changeover switch 8.

Sowohl der Wechselschalter 8 als auch die Einzelschalter 14 und 15 der Schalteinheit 13 sind über Stellglieder des Servomotors 11 steuerbar.Both the changeover switch 8 and the individual switches 14 and 15 of the switching unit 13 can be controlled via actuators of the servo motor 11.

In Figur 2 ist eine Ausbildung der Stellglieder in Form einer Nockenscheibensteuerung dargestellt. Sowohl die der Schalteinheit 13 zugeordnete Nockenscheibe 26 als auch die den Wechselschalter 8 zugeordnete Nockenscheibe 27 sind zueinander drehfest auf einer vom Servomotor 11 bei einem Stellzyklus um 360°- drehbar angetriebenen Welle angeordnet.FIG. 2 shows an embodiment of the actuators in the form of a cam disk control. Both the cam disk 26 assigned to the switching unit 13 and the cam disk 27 assigned to the changeover switch 8 are arranged rotatably relative to one another on a shaft which is driven by the servo motor 11 during a positioning cycle and can be rotated through 360 °.

Die Nockenscheibe 26 besitzt einen Nocken 28, der sich am Umfang über einen Winkel von 180° minus 2a erstreckt. Die beiden Schalttaster 29 und 30 der Einzelschalter 14 und 15 liegen um 180° versetzt an der Nockenscheibe 26 an und zwar so, daß sie in der dargestellten Ruhestellung den gleichen Abstand zu den Rampen des Nockens 28 haben, die die Umschaltpunkte festlegen.The cam disk 26 has a cam 28 which extends over the circumference over an angle of 180 ° minus 2a. The two switch buttons 29 and 30 of the individual switches 14 and 15 are offset by 180 ° on the cam disk 26 and in such a way that in the rest position shown they are at the same distance from the ramps of the cam 28 which define the switchover points.

Der Nocken 31 der Nockenscheibe 27 erstreckt sich am Umfang der Nockenscheibe 27 über 180°, wobei die Rampen des Nockens 31 ebenfalls die Umschaltpunkte festlegen. An der Nockenscheibe 27 liegt ein Schalttaster 32 des Wechselschalters 8 an u.z. derart, daß er in der Ruhelage der Anlage um einen Winkel größer als zwei a in Bewegungsrichtung 33 der Nockenscheibe 27 jeweils gegenüber einem Schaltpunkt zurückversetzt ist.The cam 31 of the cam disk 27 extends over the circumference of the cam disk 27 over 180 °, the ramps of the cam 31 likewise defining the switchover points. On the cam disc 27, a switch button 32 of the changeover switch 8 is at the same time. such that in the rest position of the system it is set back in relation to a switching point by an angle greater than two a in the direction of movement 33 of the cam disk 27.

Der Winkel a ist etwas größer als der maximal mögliche Nachlauf des Servomotors 11 nach einem halben Stellzyklus, wobei ein Stellzyklus aus einem Sperrund einem Entsperrvorgang besteht.The angle a is somewhat larger than the maximum possible overrun of the servo motor 11 after half a positioning cycle, a positioning cycle consisting of a locking and an unlocking process.

Die Funktion der Türverriegelungsanlage ist folgende: wenn aus der dargestellten Ruhestellung einer der Betriebsschalter 1 oder 2 manuell umgeschaltet wird, was z.B. durch einen Schlüssel am Türschloß erfolgt, so ist der Servomotor 11 über den Betriebsschalter 1 bzw. 2, den Strang 4, den Wechselschalter 8 und die Diode 10 mit dem Pluspol 3 verbunden und beginnt anzulaufen, wodurch sich die Nockenscheiben 26 und 27 drehen.The function of the door locking system is as follows: if one of the operating switches 1 or 2 is switched manually from the rest position shown, which e.g. done by a key on the door lock, the servo motor 11 is connected to the positive pole 3 via the operating switch 1 or 2, the line 4, the changeover switch 8 and the diode 10 and starts to run, as a result of which the cam disks 26 and 27 rotate.

Nach Überwindung des Winkels a wird der Schalttaster 29 des Einzelschalters 14 betätigt, so daß die Stelleinheiten 23 über den Strang 21 mit dem Pluspol 20 verbunden und in Offnungsrichtung angetrieben sind.After overcoming the angle a, the switch button 29 of the individual switch 14 is actuated so that the actuating units 23 are connected to the positive pole 20 via the line 21 and are driven in the opening direction.

Bevor der Schalttaster 29 wieder umschaltet, kommt es zu einem Umschalten des Schalttasters 32 des Wechselschalters 8, so daß dieser umschaltet und dadurch die Stromversorgung des Servomotors 11 vom Pluspol 3 her unterbrochen wird.Before the switch button 29 switches again, there is a switchover of the switch button 32 of the changeover switch 8, so that it switches over and thereby the power supply to the servo motor 11 is interrupted from the positive pole 3.

Da aber weiterhin der Strang 21 des Parallelschaltkreises mit dem Pluspol 20 verbunden ist, wird der Servomotor 11 trotzdem noch über die Diode 24 mit Strom versorgt und kann weiterlaufen bis der Schalttaster 29 umschaltet. Damit ist gleichzeitig die Stromversorgung sowohl des Servomotors 11 als auch der Stelleinheiten 23 unterbrochen. Da aber der Servomotor 11 nicht sofort stehen bleibt, sondern noch um etwa einen Winkel a nachläuft, ist die endgültige Ruhestellung der Nockenscheibe 26 die dargestellte Position in der die beiden Schalttaster 29 und 30 etwa gleichen Abstand zu den Rampen der Nocken 28 haben. Damit ist ein erster halber Stellzyklus der Türverriegelungsanlage abgeschlossen.However, since the line 21 of the parallel circuit is still connected to the positive pole 20, the servo motor 11 is still supplied with current via the diode 24 and can continue to run until the switch button 29 switches. The power supply to both the servo motor 11 and the actuating units 23 is thus interrupted at the same time. However, since the servo motor 11 does not stop immediately, but still travels by approximately an angle a, the final rest position of the cam disk 26 is the position shown in which the two switch buttons 29 and 30 are at approximately the same distance from the ramps of the cams 28. This completes a first half actuation cycle of the door locking system.

Der zweite halbe Stellzyklus erfolgt nach dem gleichen Ablauf in dem einer der Betriebsschalter 1 und 2 umgeschaltet wird. Nunmehr erfolgt ein Umschalten des Tastschalters 30 durch den Nocken 28, so daß der Strang 22 mit dem Pluspol 20 verbunden wird. Die Stelleinheiten 23 werden nun gegenüber dem ersten halben Stellzyklus umgepolt mit der Stromversorgung verbunden, so daß nach einem vorhergehenden Öffnungsvorgang nunmehr ein Schließvorgang von den Stelleinheiten 23 durchgeführt wird. Der weitere Ablauf entspricht dem Prinzip dem Ablauf dem ersten halben Stellzyklusses, wobei nach Umschalten des Wechselschalters nun der Servomotor 11 noch über die Diode 25 mit der Stromversorgung des Parallelschaltkreises verbunden ist und es zu einem gleichzeitigen Abschalten von Servomotor und Stelleinheit kommt.The second half control cycle follows the same sequence in which one of the operating switches 1 and 2 is switched. Now, the key switch 30 is switched by the cam 28, so that the strand 22 is connected to the positive pole 20. The actuating units 23 are now connected with the polarity reversed with respect to the first half actuating cycle, so that after a previous one Opening process now a closing process is carried out by the actuating units 23. The rest of the sequence corresponds to the principle of the sequence of the first half actuating cycle, whereby after the changeover switch has been switched over, the servo motor 11 is still connected to the power supply of the parallel circuit via the diode 25 and the servo motor and the actuating unit are switched off simultaneously.
