Description

Die Erfindung betrifft ein Kraftfahrzeugschloss, insbesondere Kraftfahrzeugtürschloss mit Drehfalle, Sperrklinke und einer auf die Drehfalle einwirkenden Zuziehhilfe in Form eines Antriebes mit Stellglied, Antriebswelle, Bowdenzug und einem dem Antriebsgehäuse zugeordneten und damit verbundenen Sensor, wobei die Drehfalle über den Antrieb aus der Vorrast motorisch bis zum Ansprechen des Sensors in die Hauptrast bewegbar ist.The invention relates to a motor vehicle lock, in particular motor vehicle door lock with a rotary latch, pawl and a force acting on the catch closing in the form of a drive with actuator, drive shaft, Bowden cable and the drive housing associated and associated sensor, wherein the catch on the drive from the pre-rest up to motor is movable to respond the sensor in the main branch.

Kraftfahrzeugtürschlösser mit einer solchen Zuziehhilfe werden auch als Servoschlösser bezeichnet. Bei derartigen Kraftfahrzeugtürschlössern, die wie üblich mit einem Gesperre aus Drehfalle und Sperrklinke zum Verrasten der Drehfalle ausgestattet sind, erfolgt beim Schließen der entsprechenden Kraftfahrzeugtür oder Kraftfahrzeugklappe eine Weiterführung der Drehfalle in die Position Hauptrast nach Einfall der Sperrklinke in die Position Vorrast mittels motorischer Kraft. Meist handelt es sich dabei um Elektromotoren. Ein solches Kraftfahrzeugtürschloss ist aus der DE 199 42 360 A1 bekannt. In der Regel werden entsprechende Kraftfahrzeugtürschlösser von einem neben dem eigentlichen Kraftfahrzeugtürschloss platzierten elektromotorischen Antrieb über eine mit der Drehfalle zusammenwirkende Zuziehhilfe beaufschlagt. Ein solcher elektromotorischer Antrieb ist Gegenstand der DE 10 2009 036 834 A1 . Dieser Antrieb weist ein Stellglied sowie eine Antriebswelle und einen Sensor auf. Ein solcher Sensor sorgt beim Rücklauf der Antriebswelle, also nach dem die Drehfalle in die Hauptrast bewegt ist, dafür, dass das System nicht auf Block fahren kann. Ein zweiter Sensor sorgt übrigens vorher dafür, dass der Antriebsmotor nach dem Einfall der Sperrklinke in die Position Vorrast den Befehl zum Anlaufen bekommt. Aus der DE 10 2011 075 611 A1 ist es bekannt, den für das wegen der Bewegung der Drehfalle in die Hauptrast benötigte Sensor neben dem Antriebsgehäuse anzuordnen und über eine verklebte Klappe nach außen hin zu schützen. Beim Rücklauf des Antriebs können auf den Sensor hohe Kräfte wirken, so dass die Klappe sich öffnen kann und die Sicherung und genaue Anordnung des Sensors am Antrieb nicht immer gegeben ist.Motor vehicle door locks with such a closing aid are also referred to as servo locks. In such motor vehicle door locks, which are equipped as usual with a locking mechanism of the catch and pawl for locking the catch occurs when closing the corresponding motor vehicle door or vehicle door a continuation of the catch in the main rest position after incidence of the pawl in the position Vorrast means of motor power. Most of these are electric motors. Such a motor vehicle door lock is from the DE 199 42 360 A1 known. In general, corresponding motor vehicle door locks are acted upon by an electromotive drive placed in addition to the actual motor vehicle door lock via a closing aid cooperating with the rotary latch. Such an electric motor drive is the subject of DE 10 2009 036 834 A1 , This drive has an actuator and a drive shaft and a sensor. Such a sensor ensures when the return shaft of the drive shaft, so after the catch is moved into the main catch, that the system can not drive to block. Incidentally, a second sensor previously ensures that the drive motor gets the command to start after the pawl has entered the pre-rest position. From the DE 10 2011 075 611 A1 It is known that the sensor required for the movement of the catch in the main branch next to to arrange the drive housing and protect it via a glued flap to the outside. During the return of the drive, high forces can act on the sensor, so that the flap can open and the securing and exact arrangement of the sensor on the drive is not always given.

Aus der den Oberbegriff des Anspruchs 1 offenbarenden DE 20 2012 004 789 U1 ist weiterhin ein Kraftfahrzeugschloss mit einer Drehfalle, einer Sperrklinke und einer auf die Drehfalle einwirkenden Zuziehhilfe in Form eines Antriebes mit einem Stellglied, einer Antriebswelle und einem Bowdenzug bekannt, wobei die Drehfalle über den Antrieb motorisch aus einer Vorrast in eine Hauptrast bewegbar ist.From the disclosing the preamble of claim 1 DE 20 2012 004 789 U1 Furthermore, a motor vehicle lock with a rotary latch, a pawl and a force acting on the catch closing aid in the form of a drive with an actuator, a drive shaft and a Bowden cable is known, wherein the rotary latch via the drive motor is movable from a preliminary catch in a main catch.

Der Erfindung liegt daher die Aufgabe zugrunde, ein Kraftfahrzeugschloss mit einem Sensor für den motorisch bewegten Bowdenzug zu schaffen, das die beim Rücklauf der Drehfalle auftretenden Kräfte sicher aufnimmt und für den sicheren Sitz des Sensors Sorge trägt.The invention is therefore based on the object to provide a motor vehicle lock with a sensor for the motor-driven Bowden cable, which safely absorbs the forces occurring during the return of the rotary latch and contributes to the secure fit of the sensor concern.

Die Aufgabe wird gemäß der Erfindung im Wesentlichen dadurch gelöst, dass der Sensor in das Antriebsgehäuse, mit dem auch das Bowdenzugwiderlager verbunden ist, integriert und ein den Sensor sichernder Deckel in dem Antriebsgehäuse verclipst ist.The object is achieved according to the invention essentially in that the sensor is integrated into the drive housing, with which the Bowdenzugwiderlager is connected, and a sensor securing lid is clipped in the drive housing.

Bei einem derart ausgerüsteten Kraftfahrzeugschloss insbesondere Kraftfahrzeugtürschloss wird vorteilhafterweise das Bowdenzugwiderlager mit dem Gehäuse ausgeführt, wodurch eine sehr stabile und kompakte Lagerung erreicht wird, d. h. das Bowdenzugwiderlager und der entsprechende Teil des Antriebsgehäuses bzw. das gesamte Antriebsgehäuse übernehmen als ein Bauteil die beim Bewegen des Bowdenzuges auftretenden Kräfte sicher. Insbesondere aber wird dieses kompakte und damit sichere Antriebsgehäuse für die Aufnahme des zu schützenden Sensors benutzt, wobei der den Sensor aufnehmende Teil des Antriebsgehäuses dann über einen den Sensor zugleich sichernden Deckel verschlossen wird, in dem der Deckel im Antriebsgehäuse verclipst ist. Nach dem Aufbringen des Deckels ist der Innenraum, in dem der Sensor untergebracht ist, nach außen hin abgeschlossen und dieser Verschluss kann auch bei auftretenden Kräften irgendwelcher Art sich nicht aus seinem Sitz selbsttätig lösen und damit den zu schützenden Sensor freigeben. Der Vorgang des Verclipsens ist darüber hinaus von Vorteil, weil dieses Festlegen des Deckels ohne weitere Zusatzmittel möglich ist, wobei sich der Deckel quasi in seine Endlage durch den Clips selbst hineinzieht.In such a motor vehicle lock, in particular motor vehicle door lock, the Bowdenzugwiderlager is advantageously carried out with the housing, whereby a very stable and compact storage is achieved, ie the Bowdenzugwiderlager and the corresponding part of the drive housing or the entire drive housing take over as a component occurring when moving the Bowden cable Forces sure. In particular, however, this compact and thus safe drive housing is used for receiving the sensor to be protected, wherein the sensor receiving part of the drive housing is then closed by a sensor at the same time securing lid in which the lid is clipped in the drive housing. After applying the cover, the interior space in which the sensor is housed, completed to the outside and this closure can not be solved automatically even when occurring forces of any kind from his seat and thus release the sensor to be protected. The process of Verclipsens is also advantageous because this setting of the lid without further additives is possible, with the cover almost pulls into its final position by the clip itself.

Die stabile und kompakte Lagerung des Sensors im Antriebsgehäuse ist vor allem auch dadurch möglich, dass das Antriebsgehäuse und das Bowdenzugwiderlager bzw. dessen Abdeckkappe einteilig ausgebildet sind. Da es sich um Kunststoffbauteile handelt, werden diese in einem Arbeitsgang hergestellt und bilden dann eine Einheit, die optimal geeignet ist, den zu schützenden Sensor aufzunehmen.The stable and compact mounting of the sensor in the drive housing is above all also possible because the drive housing and the Bowdenzugwiderlager or its cap are integrally formed. Since these are plastic components, they are manufactured in one operation and then form a unit that is optimally suited to receive the sensor to be protected.

Eine gute und sichere Lagerung des Sensors wird gemäß der Erfindung insbesondere dadurch möglich, dass der Sensor in einem parallel zum Antrieb verlaufenden Schacht im kompakten Antriebsgehäuse angeordnet ist. Dadurch ist sichergestellt, dass dieser Sensor durch die sich bewegenden Teile des Antriebes sicher angesprochen werden kann und sich dabei immer in der gleichen Position befindet, so dass Fehlschaltungen nicht auftreten können.A good and secure mounting of the sensor is in particular possible according to the invention in that the sensor is arranged in a parallel to the drive shaft in a compact drive housing. This ensures that this sensor can be safely addressed by the moving parts of the drive and is always in the same position, so that faulty circuits can not occur.

Die sichere Positionierung innerhalb des Schachtes und eine Erleichterung bei der Montage insgesamt wird erreicht, wenn der Sensor auf dem Deckel vormontiert in das Antriebsgehäuse bzw. dessen Schacht einschiebbar ausgebildet ist. Mit dem Einschieben des Sensors wird also der Deckel gleich mit in die Montageposition gebracht und dann durch das Verclipsen so festgelegt, dass damit auch gleichzeitig der Sensor in der richtigen Position festgelegt wird.The secure positioning within the shaft and a total ease of assembly is achieved when the sensor is pre-mounted on the cover in the drive housing or its shaft is designed to be inserted. With the insertion of the sensor so the lid is the same brought into the mounting position and then set by clipping so that it is also the same time the sensor is set in the correct position.

Grundsätzlich bekannt ist es, als Sensoren Mikroschalter einzusetzen. Im vorliegenden Fall ist dies aber besonders vorteilhaft, weil ein solcher Mikroschalter sich hier besonders gut dazu eignet, vormontiert auf dem Deckel in den Schacht in die jeweils richtige Position gebracht zu werden. Dort kann er seine Funktion optimal erfüllen, ohne dass es einer Nachjustierung bedarf. Außerdem wird er durch Bewegungen anderer Teile des Kraftfahrzeugschlosses bzw. des Antriebes nicht negativ beeinflusst, weil er eben sehr genau und sicher auf dem Deckel vormontiert in seine Betriebsposition gebracht wird.It is generally known to use microswitches as sensors. In the present case, however, this is particularly advantageous because such a micro switch is particularly well suited to be pre-mounted on the cover in the shaft in the correct position. There he can do his job optimally meet, without the need for readjustment. In addition, it is not adversely affected by movements of other parts of the motor vehicle lock or the drive, because it is precisely very precisely and safely placed on the cover premounted in its operating position.

Bei einer Verclipsung des Deckels im Antriebsgehäuse ist eine Demontage möglich, wenn ein Eingriff ins Antriebsgehäuse bzw. im Schaft vorgesehen ist, um den Clips zu lösen. Nach einer weiteren Ausbildung ist es aber auch möglich, den Deckel an dem Antriebsgehäuse zu verclipsen, sodass diese Befestigung auch von außerhalb des Antriebsgehäuses bzw. dessen Schacht eher wieder gelöst werden kann.In a Verclipsung the cover in the drive housing disassembly is possible when an engagement in the drive housing or in the shaft is provided to release the clips. According to a further embodiment, it is also possible to clasp the cover to the drive housing, so that this attachment can also be solved from outside the drive housing or its shaft rather again.

Der Sensor bzw. der Mikroschalter ist in der Regel im Antriebsgehäuse auch vor Feuchtigkeit geschützt angeordnet, wobei dieses dadurch abgesichert werden kann, dass der Deckel über eine Dichtung mit dem Schacht bzw. dem Außenrand des Schachtes verbunden ist. Mit dem Aufsetzen des Deckels auf den Schacht bzw. den Rand des entsprechenden Antriebsgehäuses wird mit dem Verclipsen gleichzeitig auch die Dichtung wirksam, wobei dies insbesondere dann möglich ist, wenn die Dichtung elastisch ausgebildet ist.The sensor or the microswitch is usually protected in the drive housing also protected from moisture, which can be ensured by the fact that the lid is connected via a seal with the shaft or the outer edge of the shaft. With the placement of the cover on the shaft or the edge of the corresponding drive housing with the clipping at the same time the seal is effective, and this is particularly possible if the seal is elastic.

Eine sichere und leicht zu bewerkstelligende Abschlussprüfung (End-of-Line-Prüfung) ist möglich, wenn wie erfindungsgemäß vorgesehen der Deckel außenseitig eine Öse aufweist. Diese Öse ermöglicht es dem Prüfenden den genauen und dichten Sitz des Deckels zu prüfen bzw. zur Not mit einem Hilfsgerät diese Überprüfung durch Verhaken in der Öse durchzuführen.A secure and easy-to-accomplish final test (end-of-line test) is possible if, as provided according to the invention, the lid has an eyelet on the outside. This eyelet allows the examiner to check the exact and tight fit of the lid or to perform this check by hooking in the eyelet if necessary with an auxiliary device.

Weiter vorn ist der Bowdenzug erwähnt, der sicher und genau durch den Antrieb beaufschlagt werden kann, weil das Antriebsgehäuse gleichzeitig das Bowdenzugwiderlager darstellt. Dieser Bowdenzug wird dabei an das Schloss bzw. das Antriebsgehäuse angeschlossen, in dem endseitig eine mit dem entsprechenden Baubereich oder Bauteil des Antriebsgehäuses korrespondierendes Enstück auf das Seil des Bowdenzuges aufgebracht wird. Da Bowdenzugwiderlager und Antriebsgehäuse eine Baueinheit darstellen, muss dieser Endbereich oder das Anschlussstück des Bowdenzuges von unten her in das Antriebsgehäuse eingebracht werden, was dadurch möglich ist, dass das Seil des Bowdenzuges über eine endseitig aufgepresste Stahlhülse oder ein kappenförmiges Bauteil am Anschlussstück bzw. am Bowdenzugwiderlager festlegbar ist. Solche Aufpressstücke sind zwar grundsätzlich bekannt, im vorliegenden Fall bieten sie aber den großen Vorteil, dass Ende des Bowdenzuges sicher an das Anschlussstück bzw. das Bowdenzugwiderlager anzubinden.Further ahead, the Bowden cable is mentioned, which can be acted upon safely and accurately by the drive, because the drive housing is also the Bowdenzugwiderlager. This Bowden cable is connected to the lock or the drive housing, in the end a corresponding with the corresponding construction area or component of the drive housing Enstück is applied to the cable of the Bowden cable. There Bowdenzugwiderlager and drive housing represent a structural unit, this end portion or the connecting piece of the Bowden cable must be introduced from below into the drive housing, which is thereby possible that the cable of the Bowden cable can be fixed via a steel sleeve pressed on one end or a cap-shaped component on the connection piece or on Bowdenzugwiderlager is. Although such Aufpressstücke are basically known, but in the present case, they offer the great advantage that the end of the Bowden cable securely connect to the connector or the Bowdenzugwiderlager.

Die Erfindung zeichnet sich insbesondere dadurch aus, dass ein Kraftfahrzeugschloss insbesondere Kraftfahrzeugtürschloss zur Verfügung gestellt wird, das ein zugleich als Bowdenzugwiderlager mitdienendes kompaktes Antriebsgehäuse zur Verfügung stellt, in dem zusätzlich auch noch der für den Betrieb wichtige Sensor bzw. Mikroschalter so untergebracht ist, dass er in der vorgesehen Position sicher fixiert und vor Beschädigungen gesichert ist. Darüber hinaus ist auch die Montage erleichtert, weil der Sensor bzw. Mikroschalter zusammen mit dem den Schacht für den Sensor verschließenden Deckel in diesen Schacht eingeschoben wird, wobei der Deckel als solcher mit dem Schacht bzw. dem Antriebsgehäuse durch Verclipsen sicher verbunden wird.The invention is characterized in particular by the provision of a motor vehicle lock, in particular a motor vehicle door lock, which provides a compact drive housing which simultaneously serves as a Bowden cable abutment, in which additionally the sensor or microswitch, which is important for operation, is accommodated in such a way that it securely fixed in the intended position and secured against damage. In addition, the assembly is facilitated because the sensor or microswitch is inserted together with the shaft closing the shaft for the sensor in this shaft, the cover being securely connected as such with the shaft or the drive housing by clipping.

Zu einem hier im Einzelnen nicht dargestellten Kraftfahrzeugtürschloss 1 gehört eine Zuziehhilfe 2, die aus einem Bowdenzug 3 mit Seil 4 und einem Antrieb 5 besteht. Der Antrieb 5 ist in einem recht stabilen Antriebsgehäuse 6 untergebracht, das gleichzeitig auch das Bowdenzugwiderlager 8 bildet. Die Abdeckkappe 9 des Bowdenzugwiderlagers 8 weist endseitig Ausgänge für das Seil 4 auf. Unterhalb dieses Bowdenzugwiderlagers 8 ist ein Bauteil mit einem Schacht 14 angeordnet, in dem der weiter hinten näher gezeigter Sensor 7 untergebracht ist. Über den Sensor 7 erfolgt beim Rücklauf der hier nicht gezeigten Antriebswelle, also nach dem erfolgten Bewegen der ebenfalls nicht gezeigten Drehfalle in die Hauptrast, ein Abschaltbefehl an den Motor des Antriebes 5, um so das schon erwähnte "auf Block fahren" des Systems sicher zu verhindern. Ausgangsseitig dieses Schachtes 14 ist ein Deckel 10 angeordnet, der auf eine weiter hinten beschriebene Art und Weise mit dem Antriebsgehäuse 6 bzw. dem Bowdenzugwiderlager 8 bzw. dem Schacht 14 verbunden ist. Um den sicheren Sitz dieses Deckels 10 einfach überprüfen zu können, weist er außenseitig eine Öse 17 auf.To a motor vehicle door lock 1, not shown here in detail includes a Zuziehhilfe 2, which consists of a Bowden cable 3 with cable 4 and a drive 5. The drive 5 is housed in a fairly stable drive housing 6, which also forms the Bowdenzugwiderlager 8 at the same time. The cap 9 of the Bowdenzugwiderlagers 8 has outputs for the rope 4 ends. Below this Bowdenzugwiderlagers 8, a component with a shaft 14 is arranged, in which the sensor 7 shown in detail further down is housed. About the sensor 7 takes place during the return of the drive shaft, not shown here, so after the successful movement of the rotary latch also not shown in the main branch, a shutdown command to the motor of the drive 5, so as to drive the already mentioned "drive to block" of the system safely prevent. On the output side of this shaft 14, a cover 10 is arranged, which is connected to the drive housing 6 and the Bowdenzugwiderlager 8 and the shaft 14 in a manner described further below. In order to easily check the secure fit of this cover 10, he has on the outside an eyelet 17.

Figur 2 zeigt ein geöffnetes Antriebsgehäuse 6 bzw. Bowdenzugwiderlager 8 mit dem anschließenden Schacht 14 und dem verclipsten Deckel 10, auf dem der Sensor 7, hier in Form eines Mikroschalters 15 fixiert ist. Über eine nur angedeutete Dichtung 16 ist eine wirksame Abdichtung des Schachtes 14 sichergestellt, wobei eine Verspannung der elastischen Dichtung 16 erfolgt, wenn der Deckel 10 mit seinem Clips 11 in das Antriebsgehäuse 6 bzw. in den Schacht 14 eingeschoben wird. Der Clips 11 verhakt sich dann hinter einem Teil des Schachtes 14, wobei er aus dieser Position nur durch einen hier nicht gezeigten Öffnungsbereich des Antriebsgehäuses 6 wieder gelöst werden kann. Erkennbar ist hier auch sehr deutlich der für die End-of-Line-Prüfung notwendige Außenbereich des Deckels 10 mit der Öse 17. FIG. 2 shows an open drive housing 6 and Bowdenzugwiderlager 8 with the adjoining shaft 14 and the verclipsten cover 10 on which the sensor 7, here in the form of a microswitch 15 is fixed. An only indicated seal 16 an effective seal of the shaft 14 is ensured, with a tension of the elastic seal 16 takes place when the lid 10 is inserted with its clip 11 in the drive housing 6 and in the shaft 14. The clip 11 then hooks behind a part of the shaft 14, wherein it can be released again from this position only by an opening region of the drive housing 6, not shown here. Visible here is also very clear for the end-of-line examination necessary outside of the lid 10 with the eyelet 17th

Der mit dem Deckel 10 bei der Montage vormontierte Mikroschalter 15 verfügt über Versorgungskabel 12, über die auch die entsprechenden Informationen an den hier nicht gezeigten Antrieb 5 weitergeleitet werden. Figur 3 lässt weiter erkennen, wie der Clips 11 ausgebildet ist und wie er die notwendige Nachgiebigkeit aufweisen kann, um sich hinter dem entsprechenden Bauteil 18 zu verhaken und so zu verspannen, dass damit einmal die sichere Position des Mikroschalters 15 und gleichzeitig die abdichtende Position des Deckels 10 gewährleistet ist.The preassembled with the cover 10 during assembly microswitch 15 has power cable 12 through which the corresponding information to the drive 5, not shown here are forwarded. FIG. 3 Further, it can be seen how the clip 11 is formed and how it can have the necessary flexibility to catch behind the corresponding component 18 and to clamp it so that once the secure position of the microswitch 15 and simultaneously the sealing position of the lid 10 is guaranteed.

Figur 4 schließlich zeigt den Endbereich des Seils 4, das im Antriebsgehäuse 6 bzw. im Anschlussstsück 21 festgelegt werden kann, da es endseitig eine Stahlhülse 19 oder auch ein kappenförmiges Bauteil 20 aufweist, das mit dem Seil 4 so verquetscht ist, dass damit die nötigen Kräfte auf das Seil 4 des Bowdenzuges 3 ausgeübt werden können. FIG. 4 Finally, shows the end of the rope 4, which can be set in the drive housing 6 and 21 in Anschlussstsück because it has a steel sleeve end 19 or a cap-shaped member 20 which is squeezed with the cable 4 so that the necessary forces on it the cable 4 of the Bowden cable 3 can be exercised.
