Description

Die Erfindung betrifft ein Schloß für eine bewegbare Anordnung wie Tür, Heckklappe oder dergleichen eines Fahrzeuges, gemäß dem Oberbegriff des Patentanspruches 1.The invention relates to a lock for a movable arrangement such as a door, Tailgate or the like of a vehicle, according to the preamble of claim 1.

Aus der DE 42 28 233 A1 ist ein Schloß mit Schloßbauteilen wie Drehfalle und Sperrklinke bekannt, bei dem die Sperrklinke die Drehfalle arretiert oder freigibt. Die Freigabe erfolgt in Abhängigkeit von Vorgaben einer Bedienperson, gegebenenfalls über eine Fernsteuerung, dadurch, daß ein Stellantrieb betätigt wird, der die Sperrklinke bewegt, wodurch dann die Drehfalle freigegeben wird, so daß sich die bewegbare Anordnung (wie beispielsweise Tür, Heckklappe oder dergleichen) öffnet beziehungsweise geöffnet werden kann.From DE 42 28 233 A1 is a lock with lock components such as a rotary latch and pawl known, in which the pawl locks the catch or releases. The release takes place depending on the specifications of an operator, if necessary via a remote control, in that a Actuator is operated, which moves the pawl, which then the Catch is released so that the movable assembly (such for example door, tailgate or the like) opens or can be opened.

Dieses Schloß funktioniert an und für sich zufriedenstellend, hat jedoch den Nachteil, daß aus Sicherheitsgründen noch zusätzliche Einrichtungen erforderlich sind, mittels derer eine mechanische Verbindung zwischen einer Handhabe und dem Bauteil des Schlosses gegeben oder im Notfall herstellbar ist. Bei diesem bekannten Schloß handelt es sich hierbei um eine Vielzahl von Bowdenzügen, die über eine Hebemechanik im Notfall eine Betätigung der Handhabe auf den Stellantrieb beziehungsweise die Sperrklinke übertragen. Dadurch ist eine Vielzahl von zusätzlichen Bauteilen erforderlich, die einen unverhältnismäßig hohen Montageaufwand erfordern, da in der Regel die Handhabe entfernt von dem Schloß angeordnet ist. Daher müssen die Bowdenzüge insbesondere in dem Korpus der Tür verlegt werden, was nicht nur zu einem hohen Montageaufwand, sondern auch zu hohen Materialkosten führt.This lock works in and of itself satisfactorily, but has the disadvantage that for safety reasons, additional facilities are required by means of which a mechanical connection between given a handle and the component of the lock or in an emergency can be produced. This well-known castle is a variety of Bowden cables that have a lifting mechanism in an emergency an actuation of the handle on the actuator or Transfer pawl. This makes a variety of additional components required a disproportionately high assembly effort require, since the handle is usually located away from the lock is. Therefore, the Bowden cables must be in the body in particular the door can be moved, which not only leads to a high installation effort, but also leads to high material costs.

Der Erfindung liegt daher die Aufgabe zugrunde, ein Schloß bereitzustellen, das unter Komfortaspekten die erforderlichen Sicherheitsvorkehrungen derart erfüllt, daß bei Ausfall eines Stellantriebes immer noch eine Öffnung der bewegbaren Anordnung gegeben ist.The object of the invention is therefore to provide a lock, the necessary safety precautions from a comfort point of view fulfilled in such a way that if one actuator fails, there is still one Opening of the movable arrangement is given.

Diese Aufgabe ist durch die Merkmale des Patentanspruches 1 gelöst.This object is solved by the features of claim 1.

Erfindungsgemäß ist vorgesehen, daß die Vielzahl der Bauteile aus dem genannten Stand der Technik, die die Redundanz betreffen (wie Bowdenzüge, Hebelmechanik usw.), ersetzt sind durch einen weiteren Stellantrieb, der direkt oder indirekt auf das Bauteil, insbesondere die Sperrklinke, des Schlosses wirkt. Unter dem direkten Antrieb ist zu verstehen, daß immer dann, wenn der erste Stellantrieb eingeschaltet wird, auch gleichzeitig der weitere Stellantrieb eingeschaltet wird, so daß bei Ausfall eines Stellantriebes immer noch eine weiterer Stellantrieb für das Öffnen der bewegbaren Anordnung zur Verfügung steht. Weiterhin ist unter direktem Antrieb zu verstehen, daß die Bewegung des Stellantriebes ohne Unter - oder Übersetzung beziehungsweise ohne Änderung der Übertragungsbewegung auf das Bauteil übertragen wird. Dies ist beispielsweise bei einem als Elektromagneten mit einem Stellelement ausgebildeten Stellantrieb der Fall, bei dem die Linearbewegung des Stellelementes direkt auf die Sperrklinke übertragen wird.According to the invention it is provided that the plurality of components from the state of the art mentioned, which relate to redundancy (such as Bowden cables, Lever mechanism etc.), are replaced by another actuator, that directly or indirectly on the component, especially the pawl, of the castle works. The direct drive means that whenever the first actuator is switched on, also simultaneously the further actuator is switched on, so that if one Actuator still another actuator for opening the movable arrangement is available. Furthermore is under direct Drive to understand that the movement of the actuator without lower or translation or without changing the transfer movement is transferred to the component. This is for example with one designed as an electromagnet with an actuator the case in which the linear movement of the actuating element directly on the Pawl is transmitted.

Unter einem indirekten Antrieb ist zu verstehen, daß im Normalfall im Sinne eines Öffnungsvorganges immer der erste Stellantrieb angesteuert wird und lediglich im Defektfall des ersten Stellantriebes der weitere Stellantrieb - gegebenenfalls zeitversetzt - ansteuerbar ist. Unter indirektem Antrieb ist weiterhin zu verstehen, daß die Bewegung eines Stellantriebes oder beider Stellantriebe umgesetzt (beispielsweise von einer Linearbewegung in eine Drehbewegung oder umgekehrt), untersetzt oder übersetzt wird. Damit erhöhen sich die konstruktiven Freiheiten bei der Auslegung des Schlosses in Abhängigkeit des eingesetzten Stellantriebes.An indirect drive means that in the normal case in the sense the first actuator is always actuated during an opening process and only in the event of a defect in the first actuator, the further actuator - if necessary with a time delay - can be controlled. Under indirect Drive is further understood to mean the movement of an actuator or both actuators implemented (for example by a linear movement in a rotary motion or vice versa), stocky or translated becomes. This increases the design freedom in the design of the lock depending on the actuator used.

Weitere Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben, aus denen sich vorteilhafte Wirkungen ergeben, sowie im folgenden beschrieben und anhand der Zeichnung erläutert.Further refinements of the invention are specified in the subclaims. from which there are advantageous effects, and in the following described and explained with reference to the drawing.

Die einzige Figur 1 zeigt einen Ausschnitt aus einem Schloß, bei dem Komponenten wie Fernbedienung, Handhaben mit Erfassungseinrichtungen für die Erfassung der Betätigung der Handhaben und weitere Elemente des Schlosses nicht gezeigt sind. Ein in Figur 1 mit der Bezugsziffer 1 versehener Sperrklinkenantrieb weist eine Drehfalle 2 auf, die in an sich bekannter Weise einen Schließbolzen 3 umgreift, wodurch die bewegbare Anordnung in ihrem Schließzustand gehalten wird. Die Drehfalle 2 wird in der gezeigten Stellung von einer Sperrklinke 4 arretiert, wobei die Sperrklinke 4 um einen Drehpunkt 5 bewegbar ist. Wird die Sperrklinke 4 bei Betrachtung der Figur 1 im Uhrzeigersinn um den Drehpunkt 5 teilweise gedreht, wird die Drehfalle 2 freigegeben, so daß die bewegbare Anordnung geöffnet werden kann. Die Drehfalle 2 und die Sperrklinke 4 sind jeweils mit einer Drehfallenfeder 6 und einer Sperrklinkenfeder 7 in der in Figur 1 gezeigten Position vorgespannt.The only Figure 1 shows a section of a castle in which Components such as remote control, handling with detection devices for the detection of the operation of the handles and other elements of the castle are not shown. One with the reference number in FIG 1 provided pawl drive has a rotary latch 2, which in known locking grips a locking pin 3, whereby the movable Arrangement is kept in its closed state. The catch 2 is locked in the position shown by a pawl 4, the Pawl 4 is movable about a pivot point 5. If the pawl 4 when looking at Figure 1 clockwise around the pivot point 5 partially rotated, the catch 2 is released, so that the movable assembly can be opened. The catch 2 and the pawl 4 are each with a rotary latch spring 6 and a pawl spring 7 in the in Figure 1 biased position.

In Figur 1 ist gezeigt, daß die Sperrklinke 4 angetrieben wird, was im folgenden ausgeführt wird. Alternativ dazu ist es auch denkbar, daß der Antrieb auf die Drehfalle 2 wirkt. Ebenfalls um den Drehpunkt 5 herum (oder alternativ um einen weiteren Drehpunkt) gelagert ist ein Zahnradsegment 8, das einen Freilauf gegenüber der Sperrklinke 4 aufweist und mit dieser in Anlage bringbar ist. Zu diesem Zweck ist ein Anschlag 9 an dem Zahnradsegment 8 angeordnet, wobei dieser Anschlag 9 nach Ansteuerung eines ersten Stellantriebes 10 in Wirkverbindung mit der Sperrklinke 4 bringbar ist, um so die Drehfalle 2 freizugeben. Die Drehbewegung des Stellantriebes 10, bei dem es sich beispielsweise um einen auf seiner Antriebswelle ein Ritzel 11 tragenden Elektromotor handelt, wird auf das Zahnradsegment 8 übertragen, so daß das Ritzel 11 in Verbindung mit dem Zahnradsegment 8 ein Untersetzungsgetriebe bildet. Nach Einschalten des Stellantriebes 10 erfolgt eine Verdrehung des Zahnradsegmentes 8 in Uhrzeigersinn, wodurch die Sperrklinke 4 mitgenommen wird und dadurch die Drehfalle 2 freigegeben wird. Nachdem der Stellantrieb 10 ausgeschaltet wurde, kehrt zumindest das Zahnradsegment 8 beispielsweise durch Federbelastung oder durch Umkehr der Drehrichtung des Stellantriebes 10 in seine Ausgangslage zurück, die durch einen Anschlag 12 definiert ist.In Figure 1 it is shown that the pawl 4 is driven, which in the following is performed. Alternatively, it is also conceivable that the drive acts on the catch 2. Also around pivot 5 (or alternatively, a gear segment is mounted around a further pivot point) 8, which has a freewheel opposite the pawl 4 and with this is plantable. For this purpose there is a stop 9 on the gear segment 8 arranged, this stop 9 after activation a first actuator 10 in operative connection with the pawl 4 can be brought so as to release the catch 2. The rotation of the Actuator 10, which is, for example, one on its drive shaft a pinion 11 carrying electric motor is on the Gear segment 8 transmitted so that the pinion 11 in connection with the gear segment 8 forms a reduction gear. After switching on of the actuator 10 there is a rotation of the gear segment 8 clockwise, which takes the pawl 4 and thereby the catch 2 is released. After the actuator 10 has been switched off, at least the gear segment 8 returns, for example by spring loading or by reversing the direction of rotation of the actuator 10 back to its initial position, which by a stop 12 is defined.

Erfindungsgemäß ist ein weiterer Stellantrieb 13 vorgesehen, der ebenfalls als Elektromotor ausgebildet ist, der auf seiner Antriebswelle ein weiteres Ritzel 14 trägt. In vorteilhafter Weise sind die beiden Stellantriebe 10 und 13 als baugleiche Elektromotoren ausgebildet, die kostengünstig sind und die Teilevielfalt verringern.According to the invention, a further actuator 13 is provided, which also is designed as an electric motor that on its drive shaft carries further pinion 14. The two actuators are advantageous 10 and 13 designed as identical electric motors that are inexpensive and reduce the number of parts.

Das Ritzel 14 kämmt mit einem weiteren Zahnradsegment 15, wobei das Zahnradsegment 15 ein Zahnrad 16 geringeren Durchmessers trägt, wobei dieses Zahnrad 16 mit dem Zahnradsegment 8 kämmt. Auf diese Art und Weise ist sowohl zwischen dem ersten Stellantrieb 10 und der Sperrklinke 4 als auch zwischen dem weiteren Stellantrieb 13 und der Sperrklinke 4 ein Getriebe angeordnet, wobei die beiden Getriebe gegeneinander freilaufend sind. Die beiden als Untersetzungsgetriebe ausgebildeten Getriebe sind so ausgelegt, daß das Getriebe zwischen dem weiteren Stellantrieb 13 und der Sperrklinke 4 eine höhere Untersetzung aufweist als das Getriebe zwischen dem ersten Stellantrieb 10 und der Sperrklinke 4. Dies hat den Vorteil, daß der Stellantrieb 10 ein geringes Moment (beispielsweise zwischen 1 bis 5 Nm) erzeugt, mit dem die Sperrklinke 4 in kurzer Zeit (beispielsweise im Zeitbereich zwischen 10 und 500 ms.) aus ihrer Arretierstellung in die Freigabestellung bewegt werden kann. Das weitere Untersetzungsgetriebe ist so ausgelegt, daß der Stellantrieb 13 ein hohes Moment (beispielsweise im Bereich von 10 bis 50 Nm) während einer längeren Zeitdauer (beispielsweise zwischen 1 und 5 Sek.) erzeugt. Dies hat den Vorteil, daß im Normalfall mittels des Stellantriebes 10 die bewegbare Anordnung schnell geöffnet werden kann, das heißt, daß eine schnelle Reaktionszeit bei Betätigung einer Handhabe gegeben ist, während im Defektfall ein leistungsstarker Stellantrieb, der solche Kräfte aufbringen, die erforderlich sind, um im Crashfall eine Tür des Kraftfahrzeuges, die verzogen ist, zu öffnen, zur Verfügung steht. Diese unterschiedliche Auslegung hat darüber hinaus den Vorteil, daß im Defektfalle des ersten Stellantriebes 10 durch das unkomfortabel und ungewohnt langsame Öffnen der bewegbaren Anordnung angezeigt wird, daß ein Defektfall vorliegt und gegebenenfalls ein Werkstattbesuch erforderlich ist. In Figur 1 ist noch gezeigt, daß eine Einrichtung zur Erfassung der Stellung des Bauteiles oder eines anderen Bauteiles vorgesehen ist, wobei zumindest ein Stellantrieb in Abhängigkeit von der erfaßten Stellung ansteuerbar ist. Bei dieser Einrichtung handelt es sich um einen Drehfallenschalter 17, wobei auch andere Ausgestaltungen zur Erfassung der Position der Drehfalle 2 beziehungsweise der Sperrklinke 4 oder auch der Position der Stellantriebe oder deren Getriebe möglich ist.The pinion 14 meshes with another gear segment 15, which Gear segment 15 carries a gear 16 of smaller diameter, wherein this gear 16 meshes with the gear segment 8. In this manner way is both between the first actuator 10 and the pawl 4 and between the further actuator 13 and the pawl 4 a gear arranged, the two gears against each other are free running. The two designed as a reduction gear Gearboxes are designed so that the gearbox between the other Actuator 13 and the pawl 4 has a higher reduction than the transmission between the first actuator 10 and the pawl 4. This has the advantage that the actuator 10 has a low torque (for example between 1 to 5 Nm) with which the pawl 4 in short time (for example in the time range between 10 and 500 ms.) their locking position can be moved into the release position. The further reduction gear is designed so that the actuator 13th a high moment (for example in the range of 10 to 50 Nm) during a longer period of time (for example between 1 and 5 seconds). This has the advantage that in the normal case by means of the actuator 10 movable arrangement can be opened quickly, that is, a quick response time when operating a handle is given while in the event of a defect, a powerful actuator that exerts such forces, which are required to open a door of the motor vehicle in the event of a crash, which is warped to open, is available. This different Interpretation also has the advantage that in the event of a defect in the first Actuator 10 by the uncomfortable and unusually slow Opening the movable assembly is displayed that there is a defect and a workshop visit may be required. In Figure 1 is still shown that a device for detecting the position of the component or another component is provided, at least one Actuator can be controlled depending on the detected position. at this device is a rotary latch switch 17, wherein other configurations for detecting the position of the catch 2 or the pawl 4 or the position of the actuators or whose gear is possible.

Auf einen berechtigten Öffnungswunsch der Bedienperson des Fahrers hin wird der erste Stellantrieb 10 angesteuert, die Sperrklinke 4 gibt die Drehfalle 2 frei, was mittels des Drehfallenschalters 17 erfaßt wird. In einer bevorzugten Ausgestaltung der Erfindung bleibt im Normalfall der Stellantrieb 13 deaktiviert, das heißt, daß dieser nicht angesteuert wird. Unterbleibt die Betätigung des Drehfallenschalters 17 innerhalb einer vorgebbaren Zeitspanne oder nach Ablauf einer vorgebbaren Zeitdauer, was bedeutet, daß mittels dem Stellantrieb 10 die Tür nicht geöffnet werden kann, wird an Stelle des Stellantriebes 10 der Stellantrieb 13 angesteuert, so daß mittels diesem das elektromechanische Öffnen der bewegbaren Anordnung eingeleitet wird. Darüber hinaus kann der weitere Stellantrieb 13 nach Erkennen eines Unfalls (beispielsweise bei Vorliegen eines Auslösesignals für einen Airbag) unmittelbar oder zeitverzögert eingeschaltet werden. Für den Fall, daß bei einem Unfall die Stromversorgung des Fahrzeuges ausfällt, kann zumindest für den Stellantrieb 13, idealerweise für beide Stellantriebe 10 und 13, eine Notstromversorgung vorgesehen werden. At the operator's authorized opening request the first actuator 10 is driven, the pawl 4 gives the Rotary latch 2 free, which is detected by means of the rotary latch switch 17. In a preferred embodiment of the invention remains in the normal case Actuator 13 deactivated, which means that it is not activated. The rotary latch switch 17 is not actuated within a predeterminable one Period of time or after a predetermined period of time what means that the door 10 is not opened by means of the actuator can, the actuator 13 is controlled instead of the actuator 10, so that by means of this the electromechanical opening of the movable Order is initiated. In addition, the other actuator 13 after detection of an accident (for example when a trigger signal is present for an airbag) switched on immediately or with a time delay become. In the event that the power supply to the Vehicle fails, at least for the actuator 13, ideally an emergency power supply is provided for both actuators 10 and 13 become.
