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 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 the DE 42 28 233 A1 a lock with lock components such as catch and pawl is known in which the pawl locks or releases the catch. The release takes place in response to instructions of an operator, possibly via a remote control, characterized in that an actuator is operated, which moves the pawl, whereby the catch is released, so that the movable assembly (such as 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 satisfactory, but has the disadvantage that, for safety reasons, additional facilities are required by means of which a mechanical connection between a handle and the component of the lock given or can be produced in an emergency. In this known lock, this is a variety of Bowden cables that transmit an operation of the handle on the actuator or the pawl via a lifting mechanism in an emergency. As a result, a large number of additional components is required, which require a disproportionately high installation effort, since as a rule the handle is disposed away from the lock. Therefore, the Bowden cables must be laid in particular in the body of the door, which not only leads to a high assembly cost, but also 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 invention is therefore an object of the invention to provide a lock that meets the necessary safety precautions in terms of comfort so that in case of failure of an actuator is still given an opening of the movable assembly.

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 of the cited prior art, which relate to the redundancy (such as Bowden cables, lever mechanism, etc.) are replaced by a further actuator which directly or indirectly to the component, in particular the pawl of the castle acts. Under the direct drive is to be understood that whenever the first actuator is turned on, at the same time the other actuator is turned on, so that in case of failure of an actuator still another actuator for the opening of the movable assembly is available. Furthermore, by direct drive is to be understood that the movement of the actuator is transmitted without translation or translation or without changing the transmission movement to the component. This is the case, for example, in the case of an actuator designed as an electromagnet with an actuating element, in which the linear movement of the actuating element is transmitted directly to the pawl.

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.Under an indirect drive is to be understood that in the normal case in the sense of an opening process always the first actuator is driven and only in case of failure of the first actuator of the other actuator - optionally time-shifted - can be controlled. Indirect drive is further to be understood that the movement of an actuator or both actuators implemented (for example, from a linear movement in a rotary motion or vice versa), is reduced or translated. 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 embodiments of the invention are specified in the subclaims, from which there are advantageous effects, as well as described below 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 sole Figure 1 shows a detail of a lock, in which components such as remote control, handling detectors for detecting the operation of the handles and other elements of the lock are not shown. A provided in Figure 1 by the reference numeral 1 pawl drive has a rotary latch 2, which engages in a conventional manner a locking pin 3, whereby the movable assembly is held in its closed state. The rotary latch 2 is locked in the position shown by a pawl 4, wherein the pawl 4 is movable about a pivot point 5. If the pawl 4 is partially rotated clockwise around the fulcrum 5 as viewed in FIG. 1, the catch 2 is released so that the movable assembly can be opened. The rotary latch 2 and the pawl 4 are each biased with a rotary latch spring 6 and a pawl spring 7 in the position shown in Figure 1.

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 will be explained below. Alternatively, it is also conceivable that the drive acts on the rotary latch 2. Also mounted around the pivot point 5 (or alternatively about a further pivot point) is a gear segment 8, which has a freewheeling device relative to the pawl 4 and can be brought into contact therewith. For this purpose, a stop 9 is arranged on the gear segment 8, wherein this stop 9 after activation of a first actuator 10 in operative connection with the pawl 4 can be brought, so as to release the catch 2. The rotational movement of the actuator 10, which is, for example, an electric motor supporting a pinion 11 on its drive shaft, is transmitted to the gear segment 8, so that the pinion 11 in conjunction with the gear segment 8 forms a reduction gear. After switching on the actuator 10, a rotation of the gear segment 8 takes place in a clockwise direction, whereby the pawl 4 is taken and thereby the catch 2 is released. After the actuator 10 has been turned off, at least the gear segment 8 returns, for example, by spring load or by reversing the direction of rotation of the actuator 10 in its initial position, which is defined by a stop 12.

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 is also designed as an electric motor which carries a further pinion 14 on its drive shaft. Advantageously, the two actuators 10 and 13 are designed as identical electric motors, which are inexpensive and reduce the variety 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, wherein the gear segment 15 carries a gear 16 of smaller diameter, said gear 16 meshes with the gear segment 8. In this way, a transmission is arranged both between the first actuator 10 and the pawl 4 and between the further actuator 13 and the pawl 4, wherein the two gears are free-running against each other. The two gears designed as a reduction gear are designed so that the transmission between the further 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 Moment (for example, between 1 to 5 Nm) generated with the pawl 4 in a short time (for example in the time range between 10 and 500 ms.) Can be moved from its locked position to the release position. The further reduction gear is designed so that the actuator 13 generates a high torque (for example in the range of 10 to 50 Nm) during a longer period of time (for example between 1 and 5 sec.). This has the advantage that in the normal case by means of the actuator 10, the movable assembly can be opened quickly, that is, that a fast response time is given when operating a handle, while in the event of a fault powerful actuator, apply those forces that are required in order to open in the event of a crash a door of the motor vehicle, which is warped, is available. This different design has the additional advantage that in the event of a defect of the first actuator 10 is indicated by the uncomfortable and unusually slow opening of the movable assembly that a defect is present and possibly a workshop visit is required. In Figure 1 is still shown that a means for detecting the position of the component or other component is provided, wherein at least one actuator in response to the detected position is controlled. In this device is a rotary latch switch 17, wherein other embodiments for detecting the position of the rotary latch 2 and the pawl 4 or the position of the actuators or their transmission 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.On a legitimate opening request of the operator of the driver towards the first actuator 10 is driven, the pawl 4 releases the catch 2, which is detected by the rotary latch switch 17. In a preferred embodiment of the invention, the actuator 13 is normally deactivated, that is, that this is not controlled. If the operation of the rotary latch switch 17 is omitted within a predefinable period of time or after a predetermined period of time, which means that the door can not be opened by means of the actuator 10, the actuator 13 is actuated instead of the actuator 10, so that by means of this the electromechanical opening the movable assembly is initiated. In addition, the further actuator 13 after detection of an accident (for example, in the presence of a trigger signal for an airbag) are switched on directly or delayed. In the event that the power supply of the vehicle fails in an accident, at least for the actuator 13, ideally for both actuators 10 and 13, an emergency power supply can be provided.
