Definitions
- the invention relates to a lock for a door of a motor vehicle with an actuating device.
- Such a lock has a locking mechanism, which basically comprises a rotary latch and a pawl for locking the rotary latch in a locking position and optionally a blocking lever for blocking the pawl in its locking position.
- a locking mechanism which basically comprises a rotary latch and a pawl for locking the rotary latch in a locking position and optionally a blocking lever for blocking the pawl in its locking position.
- the operating device is used to open the door or flap and therefore enables the locking mechanism to be released.
- the pawl is moved out of its locking position and, if necessary, the blocking lever is moved out of its blocking position and the locking mechanism is finally opened.
- the door or flap can then be opened.
- the operating device usually has a release lever that is operated to open or unlock the locking mechanism.
- a release lever is typically connected to a handle on the door or flap. This can be an external handle or an internal handle on the corresponding door or flap. If such a handle is operated, the release lever is operated or pivoted to unlock the locking mechanism and thus open the lock.
- a door lock for a motor vehicle comprises a locking mechanism and an actuating device for opening the locking mechanism.
- the actuating device comprises a rotatable actuator that can be rotated by an electric drive. Turning the actuator causes the locking mechanism to unlock, i.e. open.
- the locking mechanism can be opened regardless of the direction of rotation of the actuator. A specific direction of rotation is therefore not important in order to open the locking mechanism. Any possible direction of rotation therefore causes the locking mechanism to open.
- the force with which the locking mechanism is opened depends on the direction of rotation of the actuator. It can therefore be opened with different levels of force depending on the direction of rotation. This makes it possible to open the locking mechanism with less force in normal operation compared to the case where a higher force is required for opening.
- the respective position of the actuating device can be monitored or determined by one or more sensors, with the one or more sensors also being used to control and/or monitor the opening.
- the locking mechanism is opened in one direction of rotation via a traction device, in particular by a cable winch.
- the cable winch is arranged in particular close to the axis of the rotatable actuator in order to be able to provide a lever ratio with a large gear ratio and thus great force.
- the actuator is then driven in particular on its outer circumference by a drive, in particular by an electric motor and gearbox.
- the outer circumference can be designed as a gear wheel which is driven by a gear wheel of the gearbox or by a worm of the drive. A reliably functioning drive can thus be ensured.
- a cable winch just a rope or a rod can be connected to the actuator. This rope or rod transmits a pulling movement for opening the locking mechanism.
- the rope or rod are also advantageously arranged close to the axis in order to enable a lever ratio which enables the locking mechanism to be opened with great force.
- the traction device is particularly attached to the free end of the transmission lever in order to improve the leverage ratio by which the locking mechanism can be opened with great force.
- the transmission lever comprises a driver which is arranged between the free end of the transmission lever, to which the traction means is attached, and the rotation axis of the transmission lever.
- This driver can transmit a pivoting movement of the transmission lever to a pawl and thus move the pawl out of its locking position.
- the arrangement of the driver also makes it possible for the pawl to be moved out of its locking position with great force due to corresponding lever ratios.
- the driver is arranged in particular in the first half of the transmission lever, viewed from the axis on which the transmission lever is rotatably mounted. This further improves the lever ratio, which enables opening with great force.
- the actuator in one direction of rotation pivots a release lever, which can open the locking mechanism with little force when pivoted.
- This design contributes to the fact that it can be opened with very different forces.
- the actuator can comprise a bolt for this purpose, which is preferably arranged on the edge so that it can be opened particularly quickly.
- the above-mentioned designs make it possible to open with different forces and different speeds without having to provide an excessively large installation space or incurring excessive technical expenditure.
- the low force it is possible for the low force to differ from the higher force by a multiple without having to incur excessive technical expenditure.
- the low force can be provided very quickly.
- the higher force is at least four times, preferably at least six times, as great as the lower force.
- the lower force is up to 16 Newtons.
- the higher force is at least 80 Newtons, preferably at least 100 Newtons. This means that a very high level of force is available to open a lock even in exceptional situations. For normal operation, which requires only a small amount of force, the lock can be opened very quickly.
- the locking mechanism of the door lock comprises a rotary latch and a pawl for locking the rotary latch and optionally additionally a blocking lever which can block the pawl in its locking position.
- the door lock is an electrically operated door lock.
- the Figure 1 outlines an actuating device with which a pawl can be opened.
- An actuator 1 is shown, which can essentially be a wheel or disk mounted so as to rotate on an axis 2.
- a pawl 3 can be moved out of its locking position by turning it counterclockwise around its axis 4.
- the force with which the pawl 3 is moved out of its locking position depends on the direction of rotation of the actuator 1. If the actuator 1 is turned clockwise around its axis 2, an actuator bolt 5 attached to the edge of the wheel grasps a lever end of a release lever 6 and thus pivots the release lever 6 counterclockwise around its axis 7.
- the actuator bolt therefore acts as a driver.
- This pivoting movement of the release lever 6 is transmitted to the pawl 3, for example by means of a rod 8 which is fastened on the one hand to the release lever 6 and on the other hand to the free end of the pawl 3.
- a rod 8 which is fastened on the one hand to the release lever 6 and on the other hand to the free end of the pawl 3.
- a cable or the like can also be provided which connects or couples the release lever 6 and the pawl 3 in such a way that a pivoting movement of the release lever 6 is transmitted to the pawl 3.
- the actuator 1 has a cable winch 9, which is arranged on the axis 2. If the actuator 1 is rotated anti-clockwise, the cable 10 of the cable winch 9 is wound up. One end of the cable 10 is connected to the end of a transmission lever 11. The transmission lever 11 is rotatably mounted by the axis 4. The pawl 3 and the transmission lever 11 are therefore rotatably mounted by a common axis 4. If the cable 10 is wound up, the transmission lever 11 is pivoted anti-clockwise about the axis 4. This pivoting movement of the transmission lever 11 is transmitted to the pawl 3 via a driver 12 of the transmission lever 11. Viewed from the axis 4 in the direction of the attachment for the traction device 10, the driver 12 is arranged within the first half of the transmission lever 11. The pawl 3 is moved out of its locking position by the driver 12 with a significantly higher force compared to the force acting on the pawl 3 when the actuator 1 is rotated clockwise.
- Pivoting movements of the levers can be suitably limited by stops.
- a stop 13 is shown which limits a pivoting movement of the release lever 6 in an anti-clockwise direction.
- the respective position of the actuating device is monitored or determined by one or more sensors.
- Figure 1 by way of example, a microswitch 14 is shown with which the position of the actuator 1 can be detected.
- One or more elevations can be provided on the edge of the actuator for this purpose, which actuate the microswitch or alternatively several microswitches and can thus indicate the position of the actuator.
- the one or more sensors are used according to the invention to control and/or monitor the opening. For example, the device is initially opened with a lower force. If the one or more sensors determine that the pawl 3 could not be moved out of its locking position with the low force, the device is then opened with a greater force by turning the actuator 1 in the opposite direction.
- There is generally a control device (not shown) which controls the opening in the manner described above.
- the actuator 1 can be rotated about its axis 2 in both directions by an electric drive 15.
- the electric drive 15 comprises an electric motor that can drive the actuator 1 via a gear.
- the actuator 1 is a gear that is driven by another gear or a worm of the electric drive 15.
- One or more levers can be pre-tensioned by springs not shown, for example the pawl 3 by a spring in the direction of its locking position and/or the transmission lever 11 is moved by a spring towards its initial position, from which can be pivoted from the transmission lever 11 to open the locking mechanism.
- the Figure 2 outlines an alternative embodiment with only one transmission lever 11.
- This transmission lever 11 is connected to the wheel of the actuator 1 via another cable at the edge.
- the axis 2 of the actuator 1 is arranged between the two cables 8 and 10 so that the transmission lever 11 is pivoted either by the cable 8 or by the cable 10 depending on the direction of rotation of the actuator 1.
- the cable 8 can be attached by a second cable winch that reaches up to the circumference of the wheel of the actuator 1.
- the attachment or cable winch for the cable 8 is attached to the back of the actuator 1 if this is advantageous for reasons of space.
- a flexible band or a rod or linkage can also be provided, for example.
- the embodiment according to Figure 2 comprises fewer components compared to the embodiment of the Figure 1 and is therefore technically simpler in construction.
- the design of the Figure 1 However, it allows for greater differences in force and therefore has a significant advantage over the embodiment according to Figure 2 on.

Description
Die Erfindung betrifft ein Schloss für eine Tür eines Kraftfahrzeugs mit einer Betätigungseinrichtung.The invention relates to a lock for a door of a motor vehicle with an actuating device.
Ein solches Schloss weist ein Gesperre grundsätzlich umfassend eine Drehfalle und eine Sperrklinke für ein Verrasten der Drehfalle in einer Rastposition auf sowie optional einen Blockadehebel für ein Blockieren der Sperrklinke in ihrer Rastposition. Ein solches Schloss ist aus der
Die Betätigungseinrichtung dient dem Öffnen der Tür oder Klappe und ermöglicht daher ein Entrasten des Gesperres. Durch Betätigen der Betätigungseinrichtung wird die Sperrklinke aus ihrer Rastposition sowie gegebenenfalls der Blockadehebel der Blockadehebel aus seiner blockierenden Position heraus bewegt und das Gesperre schließlich geöffnet. Im Anschluss daran kann die Tür oder Klappe geöffnet werden.The operating device is used to open the door or flap and therefore enables the locking mechanism to be released. By operating the operating device, the pawl is moved out of its locking position and, if necessary, the blocking lever is moved out of its blocking position and the locking mechanism is finally opened. The door or flap can then be opened.
Die Betätigungseinrichtung verfügt üblicherweise über einen Auslösehebel, der betätigt wird, um das Gesperre zu öffnen beziehungsweise zu entrasten. Ein solcher Auslösehebel ist typischerweise mit einem Griff der Tür oder Klappe verbunden. Dabei kann es sich um einen Außengriff oder einen Innengriff der entsprechenden Tür oder Klappe handeln. Wird ein solcher Griff betätigt, so wird der Auslösehebel betätigt beziehungsweise verschwenkt, um das Gesperre zu entrasten und damit das Schloss zu öffnen.The operating device usually has a release lever that is operated to open or unlock the locking mechanism. Such a release lever is typically connected to a handle on the door or flap. This can be an external handle or an internal handle on the corresponding door or flap. If such a handle is operated, the release lever is operated or pivoted to unlock the locking mechanism and thus open the lock.
Bei elektrisch betätigten Schlössern liegt keine mechanische Verbindung zwischen dem Türgriff, zum Beispiel Türaußengriff, und dem Gesperre vor. Das Gesperre wird mittels eines elektrischen Antriebs geöffnet. Ein zugehöriger Türgriff kann beispielsweise einen elektrischen Schalter aufweisen, der das Signal für den Antrieb des Elektromotors bereitstellt. Bevorzugt werden Schneckenradgetriebe, bestehend aus Motor, Schnecke und Zahnrad, eingesetzt, da hierdurch ein großes Übersetzungsverhältnis realisiert werden kann, so dass einerseits eine sehr genaue Ansteuerung des Öffnungsmechanismus erfolgen kann und gleichzeitig hohe Auslösekräfte zur Verfügung stehen.In electrically operated locks, there is no mechanical connection between the door handle, for example the outside door handle, and the locking mechanism. The locking mechanism is opened by means of an electric drive. An associated door handle can, for example, have an electric switch that provides the signal for driving the electric motor. Worm gears, consisting of a motor, worm and gear, are preferably used, as this allows a large transmission ratio to be achieved, so that on the one hand a very precise control of the opening mechanism can take place and at the same time high release forces are available.
In Extremfällen oder unter ungünstigen Witterungsverhältnissen kann es dazu kommen, dass sehr viel größere Kräfte auf das Gesperre wirken, so dass ein üblicher Auslösemechanismus keine ausreichend hohe Kraft zum Öffnen des Gesperres bereitstellen kann. Ein solcher Fall kann beispielsweise dann eintreten, wenn die Kraftfahrzeugtür durch einen Unfall deformiert wurde, oder beispielsweise dann, wenn aufgrund von extremen Witterungseinflüssen, wie beispielsweise Kälte, erhöhte Kräfte zum Öffnen des Gesperres benötigt werden.In extreme cases or under unfavourable weather conditions, much greater forces can act on the locking mechanism, so that a conventional release mechanism cannot provide sufficient force to open the locking mechanism. Such a case can occur, for example, if the vehicle door has been deformed in an accident, or if, due to extreme weather conditions such as cold, increased forces are required to open the locking mechanism.
Die
Es ist Aufgabe der Erfindung, ein Gesperre eines elektrisch betätigten Türschlosses eines Kraftfahrzeugs zuverlässig mit hinreichend großer Kraft öffnen zu können, ohne für den Regelbetrieb einen übermäßig groß dimensionierten Elektromotor bereitstellen zu müssen und/oder ein übermäßig groß dimensioniertes Getriebeübersetzungsverhältnis.It is an object of the invention to be able to open a locking mechanism of an electrically operated door lock of a motor vehicle reliably with sufficiently high force without having to provide an excessively large electric motor and/or an excessively large gear ratio for normal operation.
Die Aufgabe wird durch ein Türschloss mit den Merkmalen des ersten Anspruchs gelöst.The problem is solved by a door lock having the features of the first claim.
Vorteilhafte Ausgestaltungen ergeben sich aus den Unteransprüchen.Advantageous embodiments emerge from the subclaims.
Zur Lösung der Aufgabe umfasst ein Türschloss für ein Kraftfahrzeug ein Gesperre und eine Betätigungseinrichtung für ein Öffnen des Gesperres. Die Betätigungseinrichtung umfasst einen drehbaren Aktuator, der durch einen elektrischen Antrieb, gedreht werden kann. Ein Drehen des Aktuators bewirkt ein Entrasten, also ein Öffnen, des Gesperres. Das Gesperre kann unabhängig von der Drehrichtung des Aktuators geöffnet werden. Es kommt also nicht auf eine bestimmte Drehrichtung an, um das Gesperre zu öffnen. Jede mögliche Drehrichtung bewirkt also ein Öffnen des Gesperres. Die Kraft, mit der das Gesperre geöffnet wird, hängt von der Drehrichtung des Aktuators ab. Es kann also abhängig von der Drehrichtung mit unterschiedlich großer Kraft geöffnet werden. Dies ermöglicht es, im Regelbetrieb mit einer geringeren Kraft zu öffnen im Vergleich zu dem Fall, der eine höhere Kraft für ein Öffnen erfordert. Im Regelbetrieb, bei dem eine übliche Kraft für ein Öffnen des Gesperres genügt, kann so schnell und mit geringem Energieaufwand geöffnet werden. Dennoch steht die Möglichkeit zur Verfügung, bei Bedarf zwar verzögert, aber dafür mit größerer Kraft öffnen zu können. Erfindungsgemäß kann die jeweilige Stellung bzw. Position der Betätigungseinrichtung durch ein oder mehrere Sensoren überwacht bzw. ermittelt werden, wobei zusätzlich die ein oder mehreren Sensoren dazu verwendet werden, um das Öffnen zu steuern und/oder zu überwachen.To solve the problem, a door lock for a motor vehicle comprises a locking mechanism and an actuating device for opening the locking mechanism. The actuating device comprises a rotatable actuator that can be rotated by an electric drive. Turning the actuator causes the locking mechanism to unlock, i.e. open. The locking mechanism can be opened regardless of the direction of rotation of the actuator. A specific direction of rotation is therefore not important in order to open the locking mechanism. Any possible direction of rotation therefore causes the locking mechanism to open. The force with which the locking mechanism is opened depends on the direction of rotation of the actuator. It can therefore be opened with different levels of force depending on the direction of rotation. This makes it possible to open the locking mechanism with less force in normal operation compared to the case where a higher force is required for opening. In normal operation, where a normal force is sufficient to open the locking mechanism, this can be done quickly and with little energy expenditure. opened. Nevertheless, it is possible to open with a delay but with greater force if necessary. According to the invention, the respective position of the actuating device can be monitored or determined by one or more sensors, with the one or more sensors also being used to control and/or monitor the opening.
In einer Ausgestaltung wird das Gesperre in der einen Drehrichtung über ein Zugmittel geöffnet und zwar insbesondere durch eine Seilwinde. Die Seilwinde ist insbesondere nahe der Achse des drehbaren Aktuators angeordnet, umso ein Hebelverhältnis mit großer Übersetzung und damit großer Kraft bereitstellen zu können. Der Aktuator wird dann insbesondere an seinem äußeren Umfang durch einen Antrieb angetrieben und zwar insbesondere durch einen Elektromotor nebst Getriebe. Der äußere Umfang kann als Zahnrad ausgestaltet sein, welches durch ein Zahnrad des Getriebes oder durch eine Schnecke des Antriebs angetrieben wird. Ein zuverlässig funktionierender Antrieb kann so sichergestellt werden. Anstelle einer Seilwinde kann aber auch lediglich ein Seil oder eine Stange mit dem Aktuator verbunden sein. Durch dieses Seil oder diese Stange wird eine Zugbewegung für ein Öffnen des Gesperres übertragen. Das Seil oder die Stange sind ebenfalls nahe der Achse vorteilhaft angeordnet, umso ein Hebelverhältnis zu ermöglichen, welches ein Öffnen des Gesperres mit großer Kraft ermöglicht.In one embodiment, the locking mechanism is opened in one direction of rotation via a traction device, in particular by a cable winch. The cable winch is arranged in particular close to the axis of the rotatable actuator in order to be able to provide a lever ratio with a large gear ratio and thus great force. The actuator is then driven in particular on its outer circumference by a drive, in particular by an electric motor and gearbox. The outer circumference can be designed as a gear wheel which is driven by a gear wheel of the gearbox or by a worm of the drive. A reliably functioning drive can thus be ensured. Instead of a cable winch, however, just a rope or a rod can be connected to the actuator. This rope or rod transmits a pulling movement for opening the locking mechanism. The rope or rod are also advantageously arranged close to the axis in order to enable a lever ratio which enables the locking mechanism to be opened with great force.
Das Zugmittel ist insbesondere am freien Ende des Übertragungshebels befestigt, um so verbessert ein Hebelverhältnis zu ermöglichen, durch das mit großer Kraft das Gesperre geöffnet werden kann.The traction device is particularly attached to the free end of the transmission lever in order to improve the leverage ratio by which the locking mechanism can be opened with great force.
In einer Ausgestaltung umfasst der Übertragungshebel einen Mitnehmer, der zwischen dem freien Ende des Übertragungshebels, an dem das Zugmittel befestigt ist, und der Drehachse des Übertragungshebels angeordnet ist. Durch diesen Mitnehmer kann eine Schwenkbewegung des Übertragungshebels auf eine Sperrklinke übertragen werden und die Sperrklinke so aus ihrer Raststellung heraus bewegt werden. Die Anordnung des Mitnehmers ermöglicht es ebenfalls, dass aufgrund entsprechender Hebelverhältnisse die Sperrklinke mit großer Kraft aus ihrer Raststellung heraus bewegt werden kann. Der Mitnehmer ist insbesondere in der ersten Hälfte des Übertragungshebels angeordnet und zwar von der Achse ausgesehen, durch die der Übertragungshebel drehbar gelagert ist. Hierdurch wird weiter verbessert ein Hebelverhältnis bereitgestellt, welches ein Öffnen mit großer Kraft ermöglicht.In one embodiment, the transmission lever comprises a driver which is arranged between the free end of the transmission lever, to which the traction means is attached, and the rotation axis of the transmission lever. This driver can transmit a pivoting movement of the transmission lever to a pawl and thus move the pawl out of its locking position. The arrangement of the driver also makes it possible for the pawl to be moved out of its locking position with great force due to corresponding lever ratios. The driver is arranged in particular in the first half of the transmission lever, viewed from the axis on which the transmission lever is rotatably mounted. This further improves the lever ratio, which enables opening with great force.
Erfindungsgemäß verschwenkt das Drehen des Aktuators in einer Drehrichtung einen Auslösehebel, der durch Verschwenken das Gesperre mit geringer Kraft zu öffnen vermag. Diese Ausgestaltung trägt dazu bei, dass mit sehr unterschiedlich großen Kräften geöffnet werden kann. Der Aktuator kann dafür einen Bolzen umfassen, der vorzugsweise randseitig angeordnet ist, umso besonders schnell öffnen zu können.According to the invention, turning the actuator in one direction of rotation pivots a release lever, which can open the locking mechanism with little force when pivoted. This design contributes to the fact that it can be opened with very different forces. The actuator can comprise a bolt for this purpose, which is preferably arranged on the edge so that it can be opened particularly quickly.
Die genannten Ausgestaltungen ermöglichen es, mit unterschiedlicher Kraft und unterschiedlicher Geschwindigkeit öffnen zu können, ohne dafür einen übermäßig großen Bauraum bereitstellen oder einen übermäßig großen technischen Aufwand betreiben zu müssen. Insbesondere ist es möglich, dass sich die geringe Kraft um ein Vielfaches von der höheren Kraft unterscheidet, ohne dafür einen übermäßig großen technischen Aufwand betreiben zu müssen. Die geringe Kraft kann sehr schnell bereitgestellt werden.The above-mentioned designs make it possible to open with different forces and different speeds without having to provide an excessively large installation space or incurring excessive technical expenditure. In particular, it is possible for the low force to differ from the higher force by a multiple without having to incur excessive technical expenditure. The low force can be provided very quickly.
Es ist möglich, dass die höhere Kraft wenigstens viermal, vorzugsweise wenigstens sechsmal, so groß ist wie die geringere Kraft. So beträgt in einer Ausführungsform die geringere Kraft bis zu 16 Newton. Die größere Kraft beträgt wenigstens 80 Newton, vorteilhaft wenigstens 100 Newton. Es steht damit eine sehr große Kraft zur Verfügung, um auch in Ausnahmesituationen ein Schloss öffnen zu können. Für den Regelbetrieb, der nur eine geringe Kraft erfordert, kann sehr schnell geöffnet werden.It is possible for the higher force to be at least four times, preferably at least six times, as great as the lower force. In one embodiment, the lower force is up to 16 Newtons. The higher force is at least 80 Newtons, preferably at least 100 Newtons. This means that a very high level of force is available to open a lock even in exceptional situations. For normal operation, which requires only a small amount of force, the lock can be opened very quickly.
Das Gesperre des erfindungsgemäßen Türschlosses umfass eine Drehfalle und eine Sperrklinke für ein Verrasten der Drehfalle und optional zusätzlich einen Blockadehebel, der die Sperrklinke in ihrer Raststellung zu blockieren vermag.The locking mechanism of the door lock according to the invention comprises a rotary latch and a pawl for locking the rotary latch and optionally additionally a blocking lever which can block the pawl in its locking position.
Das Türschloss ist ein elektrisch betätigbares Türschloss.The door lock is an electrically operated door lock.
