Description

Kraftfahrzeugtürverschluss Beschreibung:  Motor vehicle door lock Description:
Die Erfindung betrifft einen Kraftfahrzeugtürverschluss, mit einem Gesperre, und mit einem elektrischen Antrieb für ein elektrisches Öffnen des Gesperres. Ein Kraftfahrzeugtürverschluss des eingangs beschriebenen Aufbaus wird beispielhaft in der WO 02/31298 A1 der Anmelderin beschrieben. Hier ist nicht nur ein elektrisches Öffnen des Gesperres möglich, sondern wird zur Notöffnung des Gesperres zugleich eine mechanische Verbindung zwischen einem Betätigungshebel und dem Gesperre eingerichtet. Man spricht in diesem Kontext auch von der sogenannten temporären Crashredundanz (TCR). Das heißt, auch in einem sogenannten Notbetrieb oder bei einer Notöffnung, beispielsweise im Crashfall, ist sichergestellt, dass das Gesperre geöffnet werden kann, nämlich mit Hilfe des Betätigungshebels. Das elektrische Öffnen eines Gesperres mit Hilfe des elektrischen Antriebes wird regelmäßig so bewerkstelligt, dass ein Bediener beispielsweise einen Türaußengriff oder auch einen Türinnengriff beaufschlagt. Daraus resultiert regelmäßig eine Schalterbetätigung, die als Öffnungswunsch interpretiert wird und dazu führt, dass der elektrische Antrieb zum elektrischen Öffnen des Gesperres bestromt wird. Um an dieser Stelle jegliche Fehlbestromungen schon vom Ansatz her auszuschließen, werden in der Praxis zunehmend Blockierelemente eingesetzt. Mit Hilfe eines solchen Blockierelementes erfolgt eine mechanische Sicherung des elektrischen Antriebes. Um nun das elektrische Öffnen des Gesperres zu initiieren, sorgt der Türaußengriff oder Türinnengriff im Beispielfall nicht nur dafür, dass ein Schalter betätigt wird. Sondern zugleich korrespondiert diese Vorgehensweise dazu, dass das Blockierelement den elektrischen Antrieb freigibt, so dass dieser in öffnendem Sinne auf das Gesperre arbeiten kann. Das hat sich grundsätzlich bewährt. Allerdings werden an dieser Stelle oftmals mechanisch aufwendige Lösungen verfolgt. Aus diesem Grund liegt der Erfindung das technische Problem zugrunde, einen derartigen Kraftfahrzeugtürverschluss so weiter zu entwickeln, dass eine besonders kompakte und einfach aufgebaute Betätigung im Zuge des elektrischen Öffnens zur Verfügung gestellt wird. The invention relates to a motor vehicle door lock, with a locking mechanism, and with an electric drive for an electrical opening of the locking mechanism. A motor vehicle door lock of the construction described above is described by way of example in the applicant's WO 02/31298 A1. Here not only an electrical opening of the locking mechanism is possible, but at the same time a mechanical connection between an actuating lever and the locking mechanism is set up for the emergency opening of the locking mechanism. One speaks in this context of the so-called temporary Crashredundanz (TCR). That is, even in a so-called emergency operation or emergency opening, for example in the event of a crash, it is ensured that the locking mechanism can be opened, namely with the aid of the actuating lever. The electrical opening of a locking mechanism with the aid of the electric drive is regularly accomplished so that an operator, for example, an outside door handle or a door inner handle acted upon. This regularly results in a switch operation, which is interpreted as an opening request and leads to the fact that the electric drive for electrical opening of the locking is energized. In order to exclude any Fehlbestromungen already at the beginning of this approach, blocking elements are increasingly used in practice. With the help of such a blocking element is a mechanical backup of the electric drive. In order to initiate the electrical opening of the locking mechanism, the outside door handle or inside door handle in the example case not only ensures that a switch is actuated. But at the same time, this procedure corresponds to the fact that the blocking element releases the electric drive, so that it can work in the opening sense on the locking mechanism. This has proven itself in principle. However, mechanically complex solutions are often pursued at this point. For this reason, the invention is the technical problem of further developing such a motor vehicle door lock so that a particularly compact and simple design operation in the course of electrical opening is provided.
Zur Lösung dieser technischen Problemstellung ist ein gattungsgemäßer Kraftfahrzeugtürverschluss im Rahmen der Erfindung dadurch gekennzeichnet, dass ein zusätzlicher Antrieb vorgesehen ist, welcher zum elektrischen Öffnen des Gesperres mit Hilfe des elektrischen Antriebes eine mechanische Sicherung des elektrischen Antriebes durch das bereits angesprochene Blockierelement aufhebt. To solve this technical problem, a generic motor vehicle door lock in the invention is characterized in that an additional drive is provided which cancels a mechanical fuse of the electric drive by the already mentioned blocking element for electrically opening the locking mechanism by means of the electric drive.
Im Rahmen der Erfindung kommt also zunächst einmal ein zusätzlicher Antrieb zum Einsatz, welcher ergänzend zu dem elektrischen Antrieb für das eigentliche elektrische Öffnen verwendet wird. Dieser zusätzliche Antrieb sorgt dafür, dass zum elektrischen Öffnen des Gesperres eine zuvor in Eingriff befindliche mechanische Sicherung aufgehoben wird. Diese mechanische Sicherung des elektrischen Antriebes für das elektrische Öffnen ist regelmäßig so ausgelegt, dass das Blockierelement für die Sicherung des elektrischen Antriebes sorgt. Zu diesem Zweck handelt es sich bei dem Blockierelement regelmäßig um eine Achse schwenkbaren Blockierhebel. Der Blockierhebel ist regelmäßig mit wenigstens einer Blockiernase ausgerüstet, welche den elektrischen Antrieb im Falle einer Fehlbestromung und ohne Beaufschlagung eines zugehörigen Be- tätigungshebels stoppt. In the context of the invention, therefore, initially an additional drive is used, which is used in addition to the electric drive for the actual electrical opening. This additional drive ensures that a previously engaged mechanical fuse is released for electrically opening the locking mechanism. This mechanical protection of the electric drive for the electric opening is regularly designed so that the blocking element ensures the safety of the electric drive. For this purpose, it is at the blocking element regularly about an axis pivoting locking lever. The blocking lever is regularly equipped with at least one blocking lug, which stops the electric drive in the event of a faulty energization and without the intervention of an associated operating lever.
Da erfindungsgemäß der zusätzliche Antrieb realisiert ist, läst sich das elektrische Öffnen problemlos fernbedienbar initiieren. Das heißt, eine mechanische Beaufschlagung des Türgriffs ist nicht (mehr) erforderlich. Ganz abgesehen davon kann der erfindungsgemäße Kraftfahrzeugtürverschluss über eine Notöffnung bzw. im Crashfall geöffnet werden, und zwar rein mechanisch. Zu diesem Zweck sorgt der Antrieb zum elektrischen Öffnen des Gesperres im Notbetrieb dafür, dass eine Betätigungshebelkette entriegelt wird und folglich eine durchgängige mechanische Verbindung eines Türgriffs bis zum Gesperre vorliegt. Since, according to the invention, the additional drive is realized, the electric opening can easily be initiated by remote control. That is, a mechanical loading of the door handle is not (anymore) required. Quite apart from that, the motor vehicle door lock according to the invention can be opened via an emergency opening or in the event of a crash, namely purely mechanically. To this The purpose of the drive for electrically opening the locking mechanism in emergency operation ensures that an operating lever chain is unlocked and consequently there is a continuous mechanical connection of a door handle to the locking mechanism.
Weitere vorteilhafte Ausgestaltungen sind Gegenstand der Unteransprüche. Im Folgenden wird die Erfindung anhand einer lediglich ein Ausführungsbeispiel darstellenden Zeichnung näher erläutert; es zeigen: Fig. 1 den erfindungsgemäßen Kraftfahrzeugtürverschluss mit in Sicherungsstellung befindlichem Blockierelement sowie zusätzlichem Antrieb in der Stellung "aus", Further advantageous embodiments are the subject of the dependent claims. In the following the invention will be explained in more detail with reference to a drawing showing only one exemplary embodiment; 1 shows the motor vehicle door lock according to the invention with the blocking element in the securing position and additional drive in the "off" position,
Fig. 2 den Gegenstand nach Fig. 1 beim Übergang des zusätzlichen Antriebes in seine Position "ein" und den Gegenstand nach der Fig. 2 mit dem zusätzlichen Antrieb in seiner Stellung "ein" und in Entsicherungsstellung befindlichem Blockierelement. Fig. 2 shows the object of Fig. 1 at the transition of the additional drive in its position "on" and the article of FIG. 2 with the additional drive in its "on" and in Entsicherungsstellung befindlichem blocking element.
In den Figuren ist ein Kraftfahrzeugtürverschluss dargestellt, der wie üblich mit einem nicht explizit gezeigten Gesperre aus im Wesentlichen Drehfalle und Sperrklinke ausgerüstet ist. Auf das Gesperre arbeitet ein Auslösehebel 1 , welcher zusammen mit einem Blockierelement bzw. Blockierhebel 2 um eine gemeinsame Achse 3 in einem Gehäuse G gelagert ist. Eine Drehbewegung des Auslösehebels 1 um seine Achse 3 im Uhrzeigersinn führt dazu, dass das Gesperre geöffnet wird. Zu diesem Zweck arbeitet der Auslösehebel 1 auf eine Sperrklinke des Gesperres in der Weise, dass die Sperrklinke von der zugehörigen Drehfalle abgehoben wird und die Drehfalle federunterstützt öffnet. Um die beschriebene und in der Fig. 1 angedeutete Uhrzeigersinnbewegung des Auslösehebels 1 zu initiieren, ist ein elektrischer Antrieb 4, 5 vorgesehen. Der elektrische Antrieb 4, 5 setzt sich im Wesentlichen aus einem Elektromotor 4 und einer Abtriebscheibe 5 zusammen. In the figures, a motor vehicle door lock is shown, which is equipped as usual with a not explicitly shown ratchet of substantially rotary latch and pawl. On the locking mechanism operates a release lever 1, which is mounted together with a blocking element or blocking lever 2 about a common axis 3 in a housing G. A rotational movement of the release lever 1 about its axis 3 in a clockwise direction causes the locking mechanism is opened. For this purpose, the release lever 1 operates on a pawl of the locking mechanism in such a manner that the pawl is lifted from the associated rotary latch and opens the rotary latch spring-assisted. In order to initiate the described and in Fig. 1 indicated clockwise movement of the release lever 1, an electric drive 4, 5 is provided. The electric drive 4, 5 is essentially composed of an electric motor 4 and a driven pulley 5.
Der Elektromotor 4 ist ausgangsseitig mit einer Schnecke ausgerüstet, die umfangsseitig mit der Abtriebscheibe 5 kämmt. Auf diese Weise kann die Abtriebscheibe 5 Bewegungen um ihre zugehörige Achse 6 im Uhrzeigersinn und im Gegenuhrzeigersinn vollführen. Ein elektrischer Öffnungsvorgang des Gesperres korrespondiert zur in der Fig. 1 angedeuteten Gegenuhrzeigersinn- bewegung der Abtriebscheibe 5 um ihre Achse 6. Diese Gegenuhrzeigersinn- bewegung führt dazu, dass eine in Aufsicht auf die Fig. 1 unterhalb der Abtriebscheibe 5 angeordnete Kontur mit dem Auslösehebel 1 wechselwirkt und diesen in der beschriebenen Art und Weise derart beaufschlagt, dass der Auslösehebel 1 um seine Achse 3 die bereits beschriebene Uhrzeigersinndrehung zur Öffnung des Gesperres vollführt. - Mit Hilfe einer Uhrzeigersinnbewegung der Abtriebscheibe 5 wird eine Notöffnung eingeleitet, indem die gesamte Betätigungshebelkette "entriegelt" wird. Zusätzlich zu dem bereits angesprochenen elektrischen Antrieb 4, 5 für ein elektrisches Öffnen des Gesperres ist erfindungsgemäß noch ein zusätzlicher weiterer Antrieb 7, 8 realisiert. Bei diesem weiteren zusätzlichen Antrieb 7, 8 handelt es sich erneut um einen Elektromotor 7, der eine Abtriebscheibe 8 beaufschlagt. Dazu ist eine Schnecke vorgesehen, die auf eine Abtriebswelle des Elektromotors 7 aufgesteckt ist bzw. mit der Abtriebswelle verbunden ist und mit der Abtriebsscheibe 8 kämmt. Bei dem zusätzlichen weiteren Antrieb 7, 8 handelt es sich im Ausführungsbeispiel um einen Kindersicherungsantrieb und/oder einen Diebstahlsicherungsantrieb, wie nachfolgend noch näher erläutert wird. Mit Hilfe des zusätzlichen Antriebes 7, 8 kann eine mechanische Sicherung des elektrischen Antriebes 4, 5 für das elektrische Öffnen des Gesperres aufgehoben werden. Diese mechanische Sicherung des elektrischen Antriebes 4, 5 manifestiert sich in dem bereits angesprochenen Blockierelement 2. Tatsächlich greift das als Blockierhebel 2 ausgebildete Blockierelement 2 mit einer Blockiernase 2a sichernd in die Abtriebscheibe 5 des elektrischen Antriebes 4, 5 zum elektrischen Öffnen des Gesperres ein. The electric motor 4 is equipped on the output side with a worm which meshes circumferentially with the driven pulley 5. In this way, the driven pulley 5 can perform movements about its associated axis 6 in a clockwise and counterclockwise direction. An electric opening operation of the locking mechanism corresponds to the direction indicated in FIG. 1 Gegenuhrzeigersinn- movement of the driven pulley 5 about its axis 6. This Gegenuhrzeigersinn- movement causes a in plan view of FIG. 1 below the driven pulley 5 arranged contour with the release lever interacts and this acted upon in the manner described so that the release lever 1 performs about its axis 3, the already described clockwise rotation to open the locking mechanism. - With the help of a clockwise movement of the driven pulley 5 an emergency opening is initiated by the entire operating lever chain "unlocked" is. In addition to the already mentioned electric drive 4, 5 for an electrical opening of the locking device according to the invention, an additional additional drive 7, 8 realized. In this further additional drive 7, 8 is again an electric motor 7, which acts on a driven pulley 8. For this purpose, a worm is provided, which is plugged onto an output shaft of the electric motor 7 and is connected to the output shaft and meshes with the driven pulley 8. The additional additional drive 7, 8 in the exemplary embodiment is a child safety drive and / or an anti-theft drive, as will be explained in more detail below. With the help of the additional drive 7, 8, a mechanical fuse of the electric drive 4, 5 can be canceled for the electrical opening of the locking mechanism become. This mechanical securing of the electric drive 4, 5 manifests itself in the blocking element 2 already mentioned. Actually, the blocking element 2 designed as a blocking lever 2 engages with a blocking lug 2a in the driven pulley 5 of the electric drive 4, 5 for the electrical opening of the locking mechanism.
Falls also beispielsweise durch eine Fehlbestromung der elektrische Antrieb 4, 5 in Richtung eines elektrischen Öffnens des Gesperres losläuft (Gegenuhr- zeigersinnbewegung der Abtriebscheibe 5), so sorgt das in seiner in den Fig. 1 und 2 im Wesentlichen dargestellten Sicherungsstellung befindliche Blockierelement bzw. der Blockierhebel 2 dafür, dass der elektrische Antrieb 4, 5 das Gesperre letztlich nicht öffnen kann. Denn die Öffnungsbewegung des fraglichen elektrischen Antriebes 4, 5 korrespondiert dazu, dass eine Anschlagkante 5a an der Abtriebscheibe 5 gegen die Blockiernase 2a des Blockierhebels 2 fährt. Auf diese Weise wird die Bewegung des elektrischen Antriebes 4, 5 in Richtung einer Öffnungsbewegung des Gesperres gestoppt und kann der elektrische Antrieb 4, 5 insgesamt den Auslösehebel 1 nicht so weit beaufschlagen, dass das Gesperre geöffnet wird. Auf diese Weise werden etwaige Fehlbestromungen des elektrischen Antriebes 4, 5 zum elektrischen Öffnen des Gesperres aufgefangen bzw. resultieren nicht darin, dass das Gesperre unbeabsichtigt eine Öffnung erfährt. Thus, if, for example, the electrical drive 4, 5 starts running in the direction of electrical opening of the locking mechanism (counter-clockwise movement of the driven pulley 5), then the blocking element or the locking position shown substantially in FIGS Blocking lever 2 that the electric drive 4, 5 can not open the locking ultimately. Because the opening movement of the electric drive in question 4, 5 corresponds to a stop edge 5a moves on the driven pulley 5 against the blocking lug 2a of the blocking lever 2. In this way, the movement of the electric drive 4, 5 is stopped in the direction of an opening movement of the locking mechanism and the electric drive 4, 5 can not act on the trip lever 1 so far that the locking mechanism is opened. In this way, any Fehlbestromungen the electric drive 4, 5 are collected for electrically opening the locking mechanism or do not result in that the locking mechanism unintentionally undergoes an opening.
Der Blockierhebel 2 kann im Rahmen der Erfindung beispielsweise mechanisch von seinem Eingriff in den elektrischen Antrieb 4, 5 für das elektrische Öffnung des Gesperres entfernt werden. Dazu ist es lediglich erforderlich, den Blockierhebel 2 um seine Achse 3 im Uhrzeigersinn zu verschwenken, so dass der Blockierhebel 2 seine im Wesentlichen in den Fig. 1 und 2 eingenommene Sicherungsstellung verlässt und in die Entsicherungsstellung gemäß Fig. 3 übergeht. Im Rahmen der Erfindung ist neben dieser gleichsam mechanischen Ent- sicherung des Blockierelementes bzw. des Blockierhebels 2 auch bzw. insbesondere eine fernbedienbare EntSicherung möglich. Diese wird mit Hilfe des zusätzlichen Antriebes 7, 8 bewerkstelligt. Tatsächlich sorgt der zusätzliche Antrieb 7, 8 nicht nur dafür, dass das Blockierelement 2 beaufschlagt wird. Sondern der zusätzliche Antrieb 2, 3 fungiert zugleich als Sicherungsantrieb für eine Kindersicherung bzw. Diebstahlsicherung, wie nachfolgend noch näher erläutert wird. Für die Erfindung ist von besonderer Bedeutung, dass der zusätzliche Antrieb 7,The blocking lever 2 can be removed in the context of the invention, for example mechanically from its engagement in the electric drive 4, 5 for the electrical opening of the locking mechanism. For this purpose, it is only necessary to pivot the blocking lever 2 about its axis 3 in the clockwise direction, so that the blocking lever 2 leaves its securing position assumed essentially in FIGS. 1 and 2 and changes into the unlocking position according to FIG. In the context of the invention, in addition to this, as it were, mechanical release of the blocking element or of the blocking lever 2, or in particular a remote-controlled release device is also possible. This is accomplished by means of the additional drive 7, 8. In fact, the additional drive 7, 8 not only ensures that the blocking element 2 is acted upon. But the additional drive 2, 3 also acts as a backup drive for a child safety device or theft protection, as will be explained in more detail below. For the invention is of particular importance that the additional drive 7,
8 auf das Blockierelement 2 arbeitet und auch arbeiten kann. Zu diesem Zweck beaufschlagt der zusätzliche Antrieb 7, 8 einen Verbindungshebel 9. Im Rahmen des Ausführungsbeispiels ist der Verbindungshebel 9 mechanisch einerseits mit einem nachfolgend noch zu beschreibenden Verriegelungshebel 10 einerseits und andererseits dem Blockierelement bzw. Blockierhebel 2 gekoppelt. Tatsächlich verfügt der Verbindungshebel 9 über einen in eine Ausnehmung des Verriegelungshebels 10 eingreifenden Verriegelungszapfen 11. Darüber hinaus ist der Verbindungshebel 9 noch mit einem Blockierzapfen 12 ausgerüstet, welcher in eine Ausnehmung des Blockierelementes bzw. Blockierhebels 2 eingreift. 8 works on the blocking element 2 and can also work. For this purpose, the additional drive 7, 8 acts on a connecting lever 9. In the exemplary embodiment, the connecting lever 9 is mechanically coupled on the one hand with a locking lever 10 to be described below and on the other hand with the blocking element or blocking lever 2. In fact, the connecting lever 9 has a locking pin 11 engaging in a recess of the locking lever 10. In addition, the connecting lever 9 is still equipped with a blocking pin 12 which engages in a recess of the blocking element or blocking lever 2.
Wenn der zusätzliche Antrieb 7, 8 von seiner in der Fig. 1 eingenommenen Position "Kindersicherung aus" über die Fig. 2 in die Stellung "Kindersicherung ein" entsprechend der Fig. 3 verstellt wird, sorgt der an die Abtriebscheibe 8 gelenkig angeschlossene Verbindungshebel 9 dafür, dass der VerbindungshebelIf the additional drive 7, 8 is moved from its assumed in Fig. 1 position "child safety off" on Fig. 2 in the position "child safety on" according to FIG. 3, provides the articulated to the driven pulley 8 connecting lever. 9 for that the connecting lever
9 über den Blockierzapfen 12 das Blockierelement bzw. den Blockierhebel 2 im Uhrzeigersinn um seine Achse 3 verschwenkt. Als Folge hiervon verlässt der Blockierhebel bzw. das Blockierelement 2 seine Sicherungsstellung entsprechend der Fig. 1 und nimmt die Entsicherungsstellung gemäß Fig. 3 ein. Bei diesem Vorgang sorgt der Blockierhebel 2 zugleich dafür, dass ein Schalter 13 betätigt wird und die zugehörige Entsicherungsstellung des Blockierhebels 2 an eine nicht dargestellte Steuereinheit meldet. Das Signal des Schalters 13 fungiert als Öffnungssignal für den Antrieb 4, 5. 9 about the blocking pin 12, the blocking element or the blocking lever 2 is pivoted clockwise about its axis 3. As a result, the blocking lever or the blocking element 2 leaves its securing position corresponding to FIG. 1 and assumes the unlocking position according to FIG. 3. In this process, the blocking lever 2 at the same time ensures that a switch 13 is actuated and the associated Entsicherungsstellung the blocking lever. 2 to a control unit, not shown. The signal of the switch 13 acts as an opening signal for the drive 4, 5.
Wie bereits erläutert, ist der zusätzliche Antrieb 7, 8 zugleich als Sicherungs- antrieb für eine Kindersicherung ausgebildet. In der Position "Kindersicherung aus" gemäß der Fig. 1 befindet sich der Verriegelungshebel 10 in seiner Stellung "verriegelt". Demgegenüber korrespondiert die Funktionsstellung nach Fig. 3 dazu, dass sich der zusätzliche Antrieb 7, 8 in der Position "Kindersicherung ein" befindet. In beiden Fällen nimmt der Verriegelungshebel 10 seine Position "verriegelt" ein, kann aber in der Fig. 3 in die Stellung "entriegelt" verschwenkt werden. As already explained, the additional drive 7, 8 is also designed as a backup drive for a child safety device. In the position "child safety off" according to FIG. 1, the locking lever 10 is in its "locked" position. In contrast, the functional position according to FIG. 3 corresponds to the fact that the additional drive 7, 8 is in the "child safety on" position. In both cases, the locking lever 10 takes its position "locked", but can be pivoted in the Fig. 3 in the "unlocked" position.
Sobald der Blockierhebel 2 den Schalter 13 beaufschlagt hat, wird dieses Signal seitens der Steuereinheit dahingehend interpretiert, dass der elektrische Antrieb 4, 5 zum elektrischen Öffnen des Gesperres beaufschlagt werden kann (Öffnungssignal). Nachdem der zusätzliche Antrieb 7, 8 seine Position entsprechend der Fig. 3 erreicht hat, findet ein federbelasteter Rücklauf statt. Zu diesem Zweck ist die Abtriebsscheibe 8 des zusätzlichen Antriebes 7, 8 mit einer entsprechend ausgelegten Feder ausgerüstet. Dieser federbelastete Rücklauf wird durch einen Pfeil in der Fig. 3 angedeutet, welcher die Bewegung des Verbindungshebels 9 in Richtung seiner Grundstellung entsprechend der Position nach Fig. 1 andeutet. Once the blocking lever 2 has acted on the switch 13, this signal is interpreted by the control unit to the effect that the electric drive 4, 5 can be applied to the electrical opening of the locking (opening signal). After the additional drive 7, 8 has reached its position corresponding to FIG. 3, a spring-loaded return takes place. For this purpose, the driven pulley 8 of the additional drive 7, 8 is equipped with a correspondingly designed spring. This spring-loaded return is indicated by an arrow in Fig. 3, which indicates the movement of the connecting lever 9 in the direction of its basic position corresponding to the position of FIG. 1.
