Description

Die Erfindung betrifft eine Kraftfahrzeugtür, insbesondere grifflose Kraftfahrzeug-Seitentür, gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a motor vehicle door, in particular a handleless motor vehicle side door, according to the preamble of claim 1.

Die wenigstens spaltweise Öffnung von Türflügeln bei Kraftfahrzeugtüren erfolgt regelmäßig, um die vollständige Öffnung der betreffenden Kraftfahrzeugtür zu erleichtern. Insbesondere bei grifflosen Kraftfahrzeugtüren kann auf diese Weise ein Bediener den durch die spaltweise Öffnung des Türflügels gebildeten Spalt zwischen der Kraftfahrzeugkarosserie und dem Türflügel nutzen, um den Türflügel zu hintergreifen und vollständig manuell aufzuschwenken. Zu diesem Zweck beschreibt DE 10 2011 015 669 A1 sogenannte Aussteller für Kraftfahrzeugtüren und Kraftfahrzeugklappen.The door leaves of motor vehicle doors are opened at least in gaps on a regular basis in order to facilitate the complete opening of the motor vehicle door in question. In particular with handleless motor vehicle doors, an operator can use the gap between the motor vehicle body and the door leaf formed by the gap-wise opening of the door leaf in order to reach behind the door leaf and swing it open completely manually. For this purpose describes DE 10 2011 015 669 A1 so-called exhibitors for motor vehicle doors and motor vehicle flaps.

Die Lehre nach der DE 10 2011 015 669 A1 sieht zu diesen Zweck ein Hubelement vor, welches durch die Entriegelung eines zugehörigen Schlosses aktiviert wird. Das Hubelement ist zweiteilig ausgebildet und verfügt über einen Außenhebel und einen Innenhebel, die relativ zueinander schwenk- oder schiebbar ausgebildet sind und im Übrigen mit einem Antriebselement lösbar verbunden werden.The teaching according to the DE 10 2011 015 669 A1 For this purpose, a lifting element is provided, which is activated by unlocking an associated lock. The lifting element is designed in two parts and has an outer lever and an inner lever, which are designed to be pivotable or slidable relative to one another and are also releasably connected to a drive element.

Der Innenhebel ist entgegen dem Uhrzeigersinn und der Außenhebel im Uhrzeigersinn aktiv rückschwenkend ausgebildet. Auf diese Weise wird ein Aussteller zur Verfügung gestellt, der auch ein sofortiges Wiederzuschlagen der zugehörigen Kraftfahrzeugtür unbeschadet übersteht. Das hat sich bewährt, ist jedoch im Hinblick auf den hierfür notwendigen konstruktiven Aufwand verbesserungsbedürftig.The inner lever is designed to actively swing back in the counterclockwise direction and the outer lever in the clockwise direction. In this way, an exhibitor is provided that can withstand an immediate slamming of the associated motor vehicle door without damage. This has proven itself, but needs to be improved in view of the design effort required for this.

In DE 10 2009 006 948 A1 wird eine Vorrichtung zur elektromotorischen Betätigung einer Kraftfahrzeugtür beschrieben. Diese verfügt über einen Elektromotor und eine Antriebsvorrichtung mit angeschlossenem Verbindungselement zur Beaufschlagung der Tür. Die Antriebsvorrichtung weist ihrerseits eine Reibvorrichtung zur Übertragung eines maximalen Antriebsmomentes auf. Das Verbindungselement ist dabei beabstandet von einem oder mehreren Drehscharnieren für den Türflügel an die Kraftfahrzeugkarosserie angeschlossen.In DE 10 2009 006 948 A1 a device for the electric motor actuation of a motor vehicle door is described. This has an electric motor and a drive device with a connected connecting element for acting on the door. The drive device in turn has a friction device for transmitting a maximum drive torque. The connecting element is connected to the motor vehicle body at a distance from one or more rotating hinges for the door leaf.

US 2014 0 137 474 A1 , US 3 202 414 A , FR 1 494 135 A , US 2014 0 150 581 A1 und US 2009 0 0051 192 A1 beschreiben jeweils eine Kraftfahrzeugtür mit Ausstellglied. Bei jeder dieser bekannten Kraftfahrzeugtüren ist das Ausstellglied schwenkbar an der Kraftfahrzeugkarosserie befestigt. US 2014 0 137 474 A1 , US 3,202,414 A , FR 1 494 135 A , US 2014 0 150 581 A1 and US 2009 0 0051 192 A1 each describe a motor vehicle door with an opening link. In each of these known motor vehicle doors, the opening member is pivotally attached to the motor vehicle body.

Der Stand der Technik hat sich grundsätzlich bewährt. Allerdings sind die bisher verfolgten Lösungen überwiegend konstruktiv aufwendig gestaltet. Das stand bisher einer flächendeckenden Verwendung im Wege. Eine solche ist jedoch vor dem Hintergrund des zunehmenden Einsatzes sogenannter Türschlösser mit EÖ-Öffnungsfunktion (elektrisch öffnen) wünschenswert.The state of the art has basically proven itself. However, the solutions pursued so far are predominantly structurally complex. This has previously stood in the way of widespread use. However, this is desirable given the increasing use of so-called door locks with an EÖ opening function (electrically opening).

Denn bei Kraftfahrzeugtüren mit den angesprochenen EÖ-Türschlössern besteht oftmals das Problem, dass nach dem elektrischen Öffnen des fraglichen Kraftfahrzeugtürschlosses der sich zwangsläufig einstellende Spalt zwischen dem Türflügel und der Kraftfahrzeugkarosserie nicht ausreicht, damit ein Bediener einwandfrei den Türflügel hintergreifen und öffnen kann. Dieses Phänomen beobachtet man insbesondere dann, wenn die üblicherweise für die spaltweise Öffnung des Türflügels in diesem Zusammenhang verantwortlich zeichnenden Gummidichtungen in ihrem aufgebauten Dichtungsdruck nachlassen. Außerdem können etwaige Fertigungstoleranzen beim Anbau des Türflügels an die Kraftfahrzeugkarosserie dazu führen, dass prinzipbedingt der sich auf diese Weise einstellende Öffnungspalt von seiner Größe her grundsätzlich nicht ausreicht. Hier will die Erfindung insgesamt Abhilfe schaffen.In the case of motor vehicle doors with the EÖ door locks mentioned, there is often the problem that after the motor vehicle door lock in question has been electrically opened, the gap that inevitably arises between the door leaf and the motor vehicle body is not sufficient for an operator to be able to reach behind the door leaf and open it properly. This phenomenon is observed in particular when the rubber seals, which are usually responsible for the gap-wise opening of the door leaf in this context, decrease in their built-up sealing pressure. In addition, any manufacturing tolerances when attaching the door leaf to the motor vehicle body can result in the opening gap that is created in this way being fundamentally insufficient in size. The invention aims to provide a remedy here overall.

Der Erfindung liegt das technische Problem zugrunde, eine derartige Kraftfahrzeugtür so weiter zu entwickeln, dass ein sichere Öffnung des Türflügels gegenüber der Kraftfahrzeugkarosserie unter Berücksichtigung eines für die weitere Handhabung ausreichenden Spaltes mit konstruktiv einfachen Mitteln zur Verfügung gestellt wird.The invention is based on the technical problem of further developing such a motor vehicle door in such a way that a safe opening of the door leaf relative to the motor vehicle body is provided using structurally simple means, taking into account a gap sufficient for further handling.

Die Erfindung schlägt den Gegenstand des Anspruchs 1 vor. Vorteilhafte Ausführungsformen der Erfindung sind in den abhängigen Ansprüchen beschrieben.The invention proposes the subject matter of claim 1. Advantageous embodiments of the invention are described in the dependent claims.

Die Erfindung schlägt eine Kraftfahrzeugtür, insbesondere eine grifflose Kraftfahrzeug-Seitentür, vor mit einem Türflügel, zumindest einem Antrieb, und einem an den Antrieb angeschlossenen Ausstellglied zur zumindest spaltweisen Öffnung des Türflügels gegenüber einer Kraftfahrzeugkarosserie, wobei das an den Antrieb angeschlossene Ausstellglied als achsnah im Vergleich zu einer Drehachse des Türflügels angeordnetes Linearstellglied ausgebildet ist; wobei das Ausstellglied in ausgefahrener Position gegen die Kraftfahrzeugkarosserie fährt und dadurch den Türflügel wenigstens spaltweise öffnet; und wobei das Ausstellglied in eingefahrener Position nicht an der Kraftfahrzeugkarosserie anliegt.The invention proposes a motor vehicle door, in particular a handleless motor vehicle side door, with a door leaf, at least one drive, and an opening member connected to the drive for opening the door leaf at least in a gap in relation to a motor vehicle body, the opening member connected to the drive being close to the axis in comparison a linear actuator arranged relative to an axis of rotation of the door leaf is formed; wherein the opening member moves against the motor vehicle body in the extended position and thereby opens the door leaf at least in a gap; and wherein the extension member does not rest on the motor vehicle body in the retracted position.

Dabei hat es sich bewährt, wenn das Ausstellglied mit Hilfe des Antriebes überwiegend parallel zur Längserstreckung des Türflügels verstellt wird. Außerdem ist das Ausstellglied im Innern des Türflügels angeordnet, also in Richtung auf einen Innenraum der Kraftfahrzeugkarosserie hinweisend. Unabhängig davon fährt das Ausstellglied vorteilhaft in ausgefahrener Position gegen die Kraftfahrzeugkarosserie. Auf diese Weise wird der Türflügel wenigstens spaltweise geöffnet.It has proven useful if the opening element is adjusted primarily parallel to the longitudinal extent of the door leaf using the drive. In addition, the opening member is arranged inside the door leaf, i.e. pointing towards an interior of the motor vehicle body. Regardless of this, the extension member advantageously moves against the motor vehicle body in the extended position. In this way, the door leaf is opened at least in a gap.

Tatsächlich hat es sich bewährt, wenn das Ausstellglied in diesem Zusammenhang gegen eine Wand der Kraftfahrzeugkarosserie fährt, und zwar jenseits der Drehachse des Türflügels, d. h. in Verlängerung des Türflügels über die Drehachse hinaus. Die genannte Wand der Kraftfahrzeugkarosserie ist dabei überwiegend senkrecht zur Längserstreckung des Türflügels angeordnet bzw. verläuft überwiegend senkrecht zur Längserstreckung des betreffenden Türflügels. Eine derartige Wand ist typischerweise im Bereich einer Öffnung der Kraftfahrzeugkarosserie vorgesehen, welche mit Hilfe der erfindungsgemäßen Kraftfahrzeugtür verschlossen wird. Denn die fragliche Öffnung in der Kraftfahrzeugkarosserie ist regelmäßig mit der betreffenden und nach innen eingezogenen sowie umlaufenden Wand ausgerüstet, die typischerweise zur Anbringung einer Türgummidichtung, Festlegung eines Schließbolzens bzw. Schlosshalters und zur Befestigung von die Drehachse des Türflügels definierenden Scharnieren dient.In fact, it has proven useful if the opening member in this context moves against a wall of the motor vehicle body, namely beyond the axis of rotation of the door leaf, ie in an extension of the door leaf beyond the axis of rotation. The wall of the motor vehicle body mentioned is arranged predominantly perpendicular to the longitudinal extent of the door leaf or runs predominantly perpendicular to the longitudinal extent of the door leaf in question. Such a wall is typically provided in the area of an opening in the motor vehicle body, which is closed with the aid of the motor vehicle door according to the invention. The opening in question in the motor vehicle body is regularly equipped with the relevant inwardly drawn and circumferential wall, which is typically used to attach a door rubber seal, to fix a locking bolt or lock holder and to fasten hinges defining the axis of rotation of the door leaf.

Der Schließbolzen bzw. Schlosshalter wechselwirkt seinerseits mit einem Gesperre eines Kraftfahrzeugtürschlosses. Das Kraftfahrzeugtürschloss ist dabei regelmäßig innenseitig am Türflügel angebracht, so dass beim Schließen des Türflügels der Schließbolzen in das Gesperre einfährt und den Türflügel und damit die Kraftfahrzeugtür festhält.The locking bolt or lock holder in turn interacts with a locking mechanism of a motor vehicle door lock. The motor vehicle door lock is regularly attached to the inside of the door leaf, so that when the door leaf is closed, the locking bolt moves into the locking mechanism and holds the door leaf and thus the motor vehicle door in place.

Sobald nun das Gesperre geöffnet wird, sorgt der erfindungsgemäß vorgesehene Antrieb in Verbindung mit dem an den Antrieb angeschlossenen Ausstellglied dafür, dass der Türflügel zumindest spaltweise gegenüber der Kraftfahrzeugkarosserie geöffnet wird. Hierrunter ist im Rahmen der Erfindung ein Spalt zwischen dem betreffenden Türflügel und der Kraftfahrzeugkarosserie gemeint, welcher eine Größenordnung von in etwa 50 mm bis 100 mm aufweist, so dass ein Bediener problemlos mit seiner Hand den Türflügel hintergreifen und vollständig öffnen kann.As soon as the locking mechanism is opened, the drive provided according to the invention, in conjunction with the opening member connected to the drive, ensures that the door leaf is opened at least in a gap with respect to the motor vehicle body. In the context of the invention, this refers to a gap between the relevant door leaf and the motor vehicle body, which has an order of magnitude of approximately 50 mm to 100 mm, so that an operator can easily reach behind the door leaf with his hand and open it completely.

Dabei reichen in der Regel geringfügige Stellbewegungen des Ausstellgliedes aus, um die zuvor beschriebene spaltweise Öffnung unter Berücksichtigung eines Spaltes von in etwa 50 mm bis 100 mm zu realisieren. Tatsächlich haben sich an dieser Stelle Stellwege des Ausstellgliedes von beispielsweise 10 mm bis 20 mm als ausreichend erwiesen. Das lässt sich im Kern darauf zurückführen, dass das Ausstellglied zunächst einmal achsnah im Vergleich zu der Drehachse des Türflügels angeordnet ist. Da der Spalt demgegenüber am achsfernen Ende des Türflügels gemessen wird, dort wo üblicherweise auch das Kraftfahrzeugtürschloss an den Türflügel angeschlossen ist, führen selbst geringe achsnahe Stellwege jenseits der Drehfalle dazu, dass der Türflügel am achsfernen Ende eine signifikante Stellbewegung aufgrund der Hebelwirkung vollführt.As a rule, small adjustment movements of the opening member are sufficient to achieve the previously described gap-wise opening, taking into account a gap of approximately 50 mm to 100 mm. In fact, at this point, adjustment paths of the opening member of, for example, 10 mm to 20 mm have proven to be sufficient. That essentially boils down to it lead back to the fact that the opening member is initially arranged close to the axis compared to the axis of rotation of the door leaf. Since the gap, on the other hand, is measured at the end of the door leaf remote from the axis, where the motor vehicle door lock is usually connected to the door leaf, even small adjustment paths close to the axis beyond the rotary latch result in the door leaf at the end remote from the axis performing a significant actuating movement due to the lever effect.

Aus diesem Grund kann das Ausstellglied vorteilhaft als Ausstellstößel ausgebildet sein, der den zuvor beschriebenen Stellweg von beispielsweise 10 mm bis 20 mm unschwer absolviert. Zu diesem Zweck ist das Ausstellglied vorteilhaft mit einer Stellstange ausgerüstet. Die Stellstange kann von einer Stellmutter des Antriebes zur Linearverstellung beaufschlagt werden.For this reason, the opening member can advantageously be designed as an opening plunger, which easily completes the previously described adjustment path of, for example, 10 mm to 20 mm. For this purpose, the display member is advantageously equipped with an adjusting rod. The adjusting rod can be acted upon by an adjusting nut of the drive for linear adjustment.

Das heißt, mit Hilfe der Stellmutter des Antriebes wird die Stellstange linear verstellt. Dazu ist es lediglich erforderlich, dass die Stellmutter in Rotationen versetzt wird. Diese Rotationen der Stellmutter führen dazu, dass die mit der Stellmutter kämmende Stellstange entsprechend ein- oder ausgefahren wird. Dadurch lässt sich die Linerarverstellung des Ausstellstößels bzw. des Ausstellgliedes unschwer realisieren.This means that the adjusting rod is adjusted linearly with the help of the drive's adjusting nut. All that is required is that the adjusting nut is rotated. These rotations of the adjusting nut cause the adjusting rod meshing with the adjusting nut to be retracted or extended accordingly. This means that the linear adjustment of the extension plunger or the extension link can be easily achieved.

Wie bereits erläutert, verfügt der Türflügel zusätzlich über ein innenseitig angeordnetes Kraftfahrzeugtürschloss. Bei diesem Kraftfahrzeugtürschloss kann es sich um ein mechanisches Kraftfahrzeugtürschloss handeln, also ein solches, bei dem das obligatorische Gesperre auf mechanischem Wege beispielsweise über einen Türgriff und angeschlossene Verbindungselemente geöffnet wird. Erfindungsgemäß ist das fragliche Kraftfahrzeugtürschloss jedoch mit einem zugehörigen Schlossantrieb ausgerüstet und folglich als elektrisches Kraftfahrzeugtürschloss bzw. Elektroschloss ausgebildet.As already explained, the door leaf also has a motor vehicle door lock arranged on the inside. This motor vehicle door lock can be a mechanical motor vehicle door lock, i.e. one in which the mandatory locking mechanism is opened mechanically, for example via a door handle and connected connecting elements. According to the invention, however, the motor vehicle door lock in question is equipped with an associated lock drive and is therefore designed as an electric motor vehicle door lock or electric lock.

Bei dem Schlossantrieb handelt es sich im Allgemeinen um einen Öffnungsantrieb für das Gesperre. Grundsätzlich kann es sich bei dem Schlossantrieb aber auch um einen Antrieb beispielsweise zur Entriegelung des Kraftfahrzeugtürschlosses handeln. Im Falle des auf das Gesperre arbeitenden Schlossantriebes lässt sich das Kraftfahrzeugtürschloss elektrisch öffnen. Das heißt, der Schlossantrieb arbeitet in diesem Fall regelmäßig auf eine Sperrklinke des Gesperres aus Drehfalle und Sperrklinke.The lock drive is generally an opening drive for the locking mechanism. In principle it can be the case Lock drive but also a drive, for example, for unlocking the motor vehicle door lock. In the case of the lock drive working on the locking mechanism, the motor vehicle door lock can be opened electrically. This means that in this case the lock drive regularly works on a pawl of the locking mechanism consisting of a rotary latch and a pawl.

Sobald der Schlossantrieb die Sperrklinke von der Drehfalle abhebt, kann die Drehfalle federunterstützt öffnen. Zugleich wird der zuvor von der Drehfalle gefangene Schließbolzen freigegeben. Als Folge hiervon ist dann auch der Türflügel und mit ihm die gesamte Kraftfahrzeugtür frei und kann durch den von der Türgummidichtung aufgebauten Dichtungsdruck geringfügig ausgestellt werden. Sobald das Gesperre im Kraftfahrzeugtürschloss geöffnet ist, sorgt erfindungsgemäß der Antrieb für das Ausstellglied dafür, dass im Anschluss hieran der Türflügel mit Hilfe des Ausstellgliedes zumindest spaltweise geöffnet wird.As soon as the lock drive lifts the pawl from the rotary latch, the rotary latch can open with spring support. At the same time, the locking bolt previously caught by the rotary latch is released. As a result of this, the door leaf and with it the entire motor vehicle door are free and can be opened slightly by the sealing pressure built up by the door rubber seal. As soon as the locking device in the motor vehicle door lock is opened, according to the invention the drive for the opening member ensures that the door leaf is then opened at least in a gap with the help of the opening member.

Dazu ist regelmäßig eine Steuereinheit vorgesehen, welche den Antrieb für das Ausstellglied erst dann beaufschlagt, wenn das fragliche Gesperre im Kraftfahrzeugtürschloss geöffnet ist. Dazu mag dem Gesperre ein Sensor zugeordnet sein, welcher von der Steuereinheit abgefragt wird. Meldet der Sensor die Öffnung des Gesperres, so wird der Antrieb für das Ausstellglied beaufschlagt, um den Türflügel zumindest spaltweise zu öffnen.For this purpose, a control unit is regularly provided, which only acts on the drive for the opening member when the locking mechanism in question is opened in the motor vehicle door lock. For this purpose, a sensor may be assigned to the locking mechanism, which is queried by the control unit. If the sensor reports the opening of the locking mechanism, the drive for the opening link is actuated in order to open the door leaf at least in a gap.

Erfindungsgemäß fungiert der zuvor bereits angesprochene Schlossantrieb des Kraftfahrzeugtürschlosses zugleich auch als Antrieb für das Ausstellglied. In diesem Zusammenhang arbeitet der Schlossantrieb mittels eines Übertragungselementes auf das Ausstellglied. Bei diesem Übertragungselement kann es sich um einen Bowdenzug handeln. Diese Vorgehensweise ist besonders einfach gestaltet, weil lediglich ein einziger Antrieb für einerseits das elektrische Öffnen des Gesperres und damit des Kraftfahrzeugtürschlosses im Ganzen und andererseits das Ausstellen des Türflügels genutzt wird. Diese gleichsam doppelte Funktionalität des Schlossantriebes berücksichtigt, dass das elektrische Öffnen und das Ausstellen sukzessive und nacheinander erfolgen, so dass auf einen Antrieb für beide Vorgehensweisen zurückgegriffen werden kann.According to the invention, the previously mentioned lock drive of the motor vehicle door lock also functions as a drive for the opening member. In this context, the lock drive works by means of a transmission element on the opening link. This transmission element can be a Bowden cable. This procedure is particularly simple because only a single drive is used for, on the one hand, the electrical opening of the locking mechanism and thus the motor vehicle door lock as a whole and, on the other hand, for opening the door leaf. This double functionality, so to speak The lock drive takes into account that the electrical opening and opening take place successively and one after the other, so that one drive can be used for both procedures.

Der Schlossantrieb für das Kraftfahrzeugtürschloss ist als Öffnungsantrieb für das Gesperre ausgebildet. In jedem Fall arbeitet die Erfindung mit nur wenigen Konstruktionselementen, was den technologischen Aufwand und die Kosten verringert. Außerdem wird die Funktionssicherheit gesteigert.The lock drive for the motor vehicle door lock is designed as an opening drive for the locking mechanism. In any case, the invention works with only a few construction elements, which reduces the technological effort and costs. In addition, functional reliability is increased.

Dabei macht im Kern die Erfindung von der Tatsache Gebrauch, dass die spaltweise Öffnung des Türflügels am fernen Ende des Türflügels im Vergleich zu dessen Drehachse zur Verfügung gestellt werden muss. Diese Bewegung am fernen Hebelarm lässt sich durch eine viel geringere Stellbewegung am nahen Hebelarm bzw. achsnah im Vergleich zu der Drehachse initiieren. Dadurch reicht es aus, wenn das Ausstellglied als Ausstellstößel ausgebildet ist und im Rahmen der beschriebenen Linearverstellung einen Stellweg von beispielsweise 10 mm bis 20 mm vollführt.In essence, the invention makes use of the fact that the gap-wise opening of the door leaf must be provided at the far end of the door leaf compared to its axis of rotation. This movement on the far lever arm can be initiated by a much smaller actuating movement on the near lever arm or near the axis compared to the axis of rotation. This means that it is sufficient if the opening member is designed as an opening plunger and performs an adjustment path of, for example, 10 mm to 20 mm as part of the linear adjustment described.

Der Antrieb und auch das Ausstellglied sind erfindungsgemäß im Innern des Türflügels angebracht. Erfindungsgemäß hat sich jedoch die Anbringung des Antriebes und des Ausstellgliedes im Innern im Kraftfahrzeugtür bzw. an dem zugehörigen Türflügel als besonders günstig erwiesen, weil dann die weitergehende Möglichkeit besteht, den Schlossantrieb eines ohnehin obligatorischen Kraftfahrzeugtürschlosses im Innern der Kraftfahrzeugtür bzw. am Türflügel zusätzlich als Antrieb für das Ausstellglied nutzen zu können. Hierin sind die wesentlichen Vorteile zu sehen.According to the invention, the drive and also the opening member are mounted inside the door leaf. According to the invention, however, the attachment of the drive and the opening member inside the motor vehicle door or on the associated door leaf has proven to be particularly favorable, because then there is the further possibility of additionally using the lock drive of an already mandatory motor vehicle door lock inside the motor vehicle door or on the door leaf as a drive to be able to use it for the display element. This is where the main advantages can be seen.

Im Folgenden wird die Erfindung anhand einer lediglich ein Ausführungsbeispiel darstellenden Zeichnung näher erläutert; es zeigen:

  • Fig. 1 den erfindungsgemäßen Türflügel in einem schematischen Längsschnitt und
  • Fig. 2A und 2B Details aus der Fig. 1 und zwar das Kraftfahrzeugtürschloss in einer Übersicht (Fig. 2A) und den Antrieb mit angeschlossenem Ausstellglied (Fig. 2B).
The invention is explained in more detail below using a drawing that only shows an exemplary embodiment; show it:
  • Fig. 1 the door leaf according to the invention in a schematic longitudinal section and
  • Fig. 2A and 2 B Details from the Fig. 1 namely the motor vehicle door lock in an overview ( Fig. 2A ) and the drive with connected opening element ( Fig. 2B ).

In der Fig. 1 ist eine Kraftfahrzeugtür in schematischem Längsschnitt dargestellt. Bei der Kraftfahrzeugtür handelt es sich nicht einschränkend um eine grifflose Kraftfahrzeug-Seitentür. Die Kraftfahrzeugtür bzw. Kraftfahrzeug-Seitentür ist in ihrem grundsätzlichen Aufbau mit einem Türflügel 1 ausgerüstet, welcher über eine Drehachse 2 an eine Kraftfahrzeugkarosserie 3 schwenkbeweglich angeschlossen ist. Tatsächlich wird die Drehachse 2 von einem oder mehreren Scharnieren definiert, mit deren Hilfe der Türflügel 1 gelenkig an die Kraftfahrzeugkarosserie 3 angeschlossen ist, und zwar an eine Wand 16, die nachfolgend noch näher in Bezug genommen wird.In the Fig. 1 A motor vehicle door is shown in a schematic longitudinal section. The motor vehicle door is, without limitation, a handleless motor vehicle side door. The basic structure of the motor vehicle door or motor vehicle side door is equipped with a door leaf 1, which is pivotally connected to a motor vehicle body 3 via a rotation axis 2. In fact, the axis of rotation 2 is defined by one or more hinges, with the help of which the door leaf 1 is articulated to the motor vehicle body 3, namely to a wall 16, which will be referred to in more detail below.

Tatsächlich kann der Türflügel 1 in der Fig. 1 durch einen Doppelpfeil angedeutete Schwenkbewegungen im Vergleich zu der Drehachse 2 vollführen. Im Innern der Kraftfahrzeugtür bzw. dessen Türflügel 1 erkennt man noch ein in der Fig. 1 lediglich schematisch angedeutetes Kraftfahrzeugtürschloss 4, welches im Detail in der Fig. 2A dargestellt ist. Das Kraftfahrzeugtürschloss 4 im Innern des Türflügels 1 wechselwirkt mit einem an eine B-Säule bzw. allgemein die Kraftfahrzeugkarosserie 3 angeschlossenen Schließbolzen 5. Dazu weist das Kraftfahrzeugtürschloss 4 in seinem Innern im Wesentlichen ein Gesperre 6, 7 auf, welches sich aus einer Drehfalle 6 und einer Sperrklinke 7 zusammensetzt. Der Schließbolzen 5 ist ebenfalls an der umlaufenden Wand 16 der Kraftfahrzeugkarosserie 3 festgelegt.In fact, the door leaf 1 can be in the Fig. 1 carry out pivoting movements indicated by a double arrow in comparison to the axis of rotation 2. Inside the motor vehicle door or its door leaf 1 you can still see one in the Fig. 1 only schematically indicated motor vehicle door lock 4, which is shown in detail in the Fig. 2A is shown. The motor vehicle door lock 4 inside the door leaf 1 interacts with a locking bolt 5 connected to a B-pillar or generally to the motor vehicle body 3. For this purpose, the motor vehicle door lock 4 essentially has a locking mechanism 6, 7 in its interior, which consists of a rotary latch 6 and a pawl 7 is composed. The locking bolt 5 is also fixed to the peripheral wall 16 of the motor vehicle body 3.

Im Ausführungsbeispiel nach der Fig. 2A ist das Kraftfahrzeugtürschloss 4 als sogenanntes Elektroschloss ausgebildet, welches ein elektrisches Öffnen des Gesperres 6, 7 ermöglicht. Zu diesem Zweck verfügt das Kraftfahrzeugtürschloss 4 in seinem Innern zusätzlich noch über einen Schlossantrieb 8, 9. Der Schlossantrieb 8, 9 setzt sich aus einerseits einem Elektromotor 8 und andererseits einer von dem Elektromotor 8 angetriebenen Steuerscheibe 9 zusammen.In the exemplary embodiment according to the Fig. 2A the motor vehicle door lock 4 is designed as a so-called electric lock, which enables the locking mechanism 6, 7 to be opened electrically. For this purpose, the motor vehicle door lock 4 also has a lock drive 8, 9 inside. The lock drive 8, 9 consists of, on the one hand, an electric motor 8 and on the other hand, a control disk 9 driven by the electric motor 8.

Je nach einer von dem Elektromotor 8 initiierten Drehbewegung der Steuerscheibe 9 arbeitet die Steuerscheibe 9 auf die Sperrklinke 7, um diese von der Drehfalle 6 abzugeben. Den entsprechenden Befehl hierfür erhält der Elektromotor 8 über eine angedeutete Steuereinheit 10. Die Steuereinheit 10 mag wiederum den Öffnungsbefehl über einen Türschlüssel, die Annäherung eines Bedieners ("keyless entry") oder auch ganz einfach dadurch erhalten, dass der Bediener einen Türflügel betätigt.Depending on a rotational movement of the control disk 9 initiated by the electric motor 8, the control disk 9 works on the pawl 7 in order to release it from the rotary latch 6. The electric motor 8 receives the corresponding command for this via an indicated control unit 10. The control unit 10 may in turn receive the opening command via a door key, the approach of an operator ("keyless entry") or simply by the operator operating a door leaf.

Jedenfalls führt der zulässige Öffnungsbefehl dazu, dass die Steuereinheit 10 den Elektromotor 8 in dem Sinne beaufschlagt, dass dieser über die Steuerscheibe 9 das Gesperre 6, 7 wie beschrieben öffnet. Als Folge hiervon kann die Drehfalle 6 aufschwenken, wie dies in der Fig. 2A durch einen Pfeil angedeutet ist. Dadurch wird der zuvor gefangene Schließbolzen 5 freigegeben. Gleiches gilt für den Türflügel 1 und mit ihm die gesamte Kraftfahrzeugtür. Sobald die Drehfalle 6 vollständig geöffnet ist, betätigt diese einen in der Fig. 2A angedeuteten Sensor 11, welcher das entsprechende Öffnungssignal an die Steuereinheit 10 übermittelt.In any case, the permissible opening command results in the control unit 10 acting on the electric motor 8 in the sense that it opens the locking mechanism 6, 7 via the control disk 9 as described. As a result of this, the rotary latch 6 can swing open, as in the Fig. 2A is indicated by an arrow. This releases the previously caught locking bolt 5. The same applies to the door leaf 1 and with it the entire motor vehicle door. As soon as the rotary latch 6 is fully opened, it activates one in the Fig. 2A indicated sensor 11, which transmits the corresponding opening signal to the control unit 10.

Ein Ausstellglied 14 ist ein Ausstellstößel 14.An opening member 14 is an opening plunger 14.

Das Ausstellglied bzw. der Ausstellstößel 14 ist seinerseits mit einer Stellstange 14', ausgerüstet, die mit einer Stellmutter 13 wechselwirkt. Tatsächlich greift die Stellstange 14', des Ausstellstößels 14 mit ihrem Außengewinde in ein Innengewinde der Stellmutter 13 ein.The opening member or the opening plunger 14 is in turn equipped with an adjusting rod 14 ', which interacts with an adjusting nut 13. In fact, the adjusting rod 14 'of the extension plunger 14 engages with its external thread in an internal thread of the adjusting nut 13.

Anhand der Fig. 1 wird deutlich, dass das Ausstellglied bzw. der Ausstellstößel 14 in ausgefahrener Position gegen die Kraftfahrzeugkarosserie 3 fährt. Tatsächlich ist die Kraftfahrzeugkarosserie 3 im Bereich einer mit Hilfe des Türflügels 1 verschlossenen Öffnung 15 der Kraftfahrzeugkarosserie 3 mit der umlaufenden Wand 16 ausgerüstet, die überwiegend senkrecht zur Längserstreckung des Türflügels 1 verläuft und die bereits angesprochenen Scharniere für den Türflügel 1 trägt sowie den Schließbolzen 5. Außerdem ist die fragliche Wand 16 meistens noch mit einer nicht ausdrücklich dargestellten umlaufenden Gummidichtung ausgerüstet.Based on Fig. 1 It becomes clear that the extension member or the extension plunger 14 moves against the motor vehicle body 3 in the extended position. In fact, the motor vehicle body 3 is in the area of an opening 15 of the motor vehicle body 3 that is closed with the help of the door leaf 1 circumferential wall 16, which runs predominantly perpendicular to the longitudinal extent of the door leaf 1 and carries the already mentioned hinges for the door leaf 1 as well as the locking bolt 5. In addition, the wall 16 in question is usually equipped with a circumferential rubber seal, which is not expressly shown.

Man erkennt anhand der Fig. 1, dass das Ausstellglied 14 überwiegend parallel zur Längserstreckung des Türflügels 1 verstellt wird. Das ist in der Fig. 1 durch einen entsprechenden Doppelpfeil angedeutet, welcher zur Kennzeichnung des Verstellweges x des Ausstellgliedes 14 dient. Der an dieser Stelle realisierte Verstellweg x beträgt im Ausführungsbeispiel ca. 10 bis 20 mm.You can tell from the Fig. 1 that the opening member 14 is adjusted predominantly parallel to the longitudinal extent of the door leaf 1. That's in the Fig. 1 indicated by a corresponding double arrow, which serves to identify the adjustment path x of the opening member 14. The adjustment path x realized at this point is approximately 10 to 20 mm in the exemplary embodiment.

Da das Ausstellglied 14 als achsnah im Vergleich zu der Drehachse 2 des Türflügels 1 angeordnetes Linearstellglied ausgebildet ist, führt der fragliche Verstellweg x des Ausstellgliedes 14 aufgrund der Hebelwirkung am achsfernen Ende des Türflügels 1 im Vergleich zu der Drehachse 2 zu signifikanten und in der Fig. 1 angedeuteten größeren Stellbewegungen. Tatsächlich beobachtet man hier am achsfernen Ende des Türflügels 1 im Vergleich zu der Drehachse 2 einen Stellweg y, welcher ca. 50 mm bis 100 mm beträgt. Dieser Stellweg y korrespondiert zu einer zumindest spaltweisen Öffnung des Türflügels 1 gegenüber der Kraftfahrzeugkarosserie 3, die mit Hilfe des Ausstellgliedes 14 erreicht und umgesetzt wird. Der Stellweg y bzw. die dadurch erreichte spaltweise Öffnung des Türflügels 1 reicht in der Regel aus, damit ein Bediener durch den geschaffenen Spalt hindurch den Türflügel 1 hintergreifen und vollständig öffnen kann.Since the opening member 14 is designed as a linear actuator arranged close to the axis compared to the axis of rotation 2 of the door leaf 1, the adjustment path x in question of the opening member 14 leads to significant and in the Fig. 1 indicated larger adjustment movements. In fact, at the end of the door leaf 1 remote from the axis, compared to the axis of rotation 2, an adjustment path y is observed, which is approximately 50 mm to 100 mm. This adjustment path y corresponds to an at least gap-wise opening of the door leaf 1 relative to the motor vehicle body 3, which is achieved and implemented with the help of the opening member 14. The travel y or the resulting gap-like opening of the door leaf 1 is generally sufficient for an operator to be able to reach behind the door leaf 1 through the gap created and open it completely.

Das alles lässt sich primär darauf zurückführen, dass das Ausstellglied bzw. der Ausstellstößel 14 achsnah im Vergleich zu der Drehachse 2 angeordnet ist und im Übrigen parallel zur Längserstreckung des Türflügels 1 verstellt wird. Dadurch kann das Ausstellglied 14 gegen die Wand 16 der Kraftfahrzeugkarosserie 3 fahren, und zwar jenseits der Drehachse 2 des Türflügels 1, wobei die fragliche Wand 16 darüber hinaus überwiegend senkrecht zur Längserstreckung des Türflügels 1 verläuft.All of this can be attributed primarily to the fact that the opening member or the opening plunger 14 is arranged close to the axis in comparison to the axis of rotation 2 and is otherwise adjusted parallel to the longitudinal extent of the door leaf 1. As a result, the opening member 14 can move against the wall 16 of the motor vehicle body 3, namely beyond the axis of rotation 2 of the Door leaf 1, the wall 16 in question also running predominantly perpendicular to the longitudinal extent of the door leaf 1.

Erfindungsgemäß zeigt Fig. 1, dass der Schlossantrieb bzw. Öffnungsantrieb 8, 9 zugleich als Antrieb 8, 9 für das Ausstellglied 14 fungiert. Zu diesem Zweck ist der Schlossantrieb 8, 9 mit Hilfe eines in der Fig. 1 gestrichelt angedeuteten Übertragungselementes 17 mit dem Ausstellglied 14 gekoppelt. Bei diesem Übertragungselement 17 kann es sich um ein mechanisches oder elektrisches Übertragungselement 17 handeln.According to the invention shows Fig. 1 that the lock drive or opening drive 8, 9 also functions as a drive 8, 9 for the opening member 14. For this purpose, the lock drive 8, 9 is with the help of one in the Fig. 1 Transmission element 17 indicated by dashed lines is coupled to the opening member 14. This transmission element 17 can be a mechanical or electrical transmission element 17.

Sofern eine mechanische Verbindung zwischen dem Schlossantrieb 8, 9 und dem Ausstellglied 14 realisiert ist, wird man an dieser Stelle bevorzugt mit einem Bowdenzug arbeiten. Der Bowdenzug kann dabei beispielsweise von dem Kraftfahrzeugtürschloss 4 bzw. dessen Antrieb 8, 9 derart beaufschlagt werden, dass mit Hilfe des Bowdenzuges bzw. des mechanischen Verbindungselementes 17 unmittelbar die Stellmutter 13 in Rotationen versetzt wird, damit auf diese Weise das Ausstellglied bzw. der Ausstellstößel 14 die gewünschte Linearverstellung unter Berücksichtigung des Stellweges x vollführt. Das ist grundsätzlich angedeutet.If a mechanical connection between the lock drive 8, 9 and the opening member 14 is implemented, it is preferred to work with a Bowden cable at this point. The Bowden cable can, for example, be acted upon by the motor vehicle door lock 4 or its drive 8, 9 in such a way that with the help of the Bowden cable or the mechanical connecting element 17, the adjusting nut 13 is immediately set in rotation, so that in this way the opening member or the opening plunger 14 carries out the desired linear adjustment taking into account the travel distance x. This is basically implied.

Dabei wird der Schlossantrieb 8, 9, der zugleich auch als Antrieb 8, 9 für das Ausstellglied 14 fungiert, erst dann beaufschlagt, wenn das Gesperre 6, 7 im Kraftfahrzeugtürschloss 4 geöffnet ist. Dazu ist die Steuereinheit 10 in Verbindung mit dem Sensor 11 vorgesehen.The lock drive 8, 9, which also functions as a drive 8, 9 for the opening member 14, is only acted upon when the locking mechanism 6, 7 in the motor vehicle door lock 4 is opened. For this purpose, the control unit 10 is provided in conjunction with the sensor 11.

Das heißt, erst wenn der Sensor 11 ein entsprechendes Öffnungssignal an die Steuereinheit 10 abgibt, sorgt die Steuereinheit 10 dafür, dass der Schlossantrieb 8, 9 den Ausstellstößel 14 wie beschrieben beaufschlagt und ausgefahren wird. Als Folge hiervon wird dann der Türflügel 1 wunschgemäß wenigstens spaltweise gegenüber der Kraftfahrzeugkarosserie 3 geöffnet, so dass der Bediener den Türflügel 1 und damit die gesamte Kraftfahrzeugtür unschwer manuell vollständig öffnen kann.This means that only when the sensor 11 sends a corresponding opening signal to the control unit 10 does the control unit 10 ensure that the lock drive 8, 9 acts on the opening plunger 14 and extends it as described. As a result of this, the door leaf 1 is then opened, as desired, at least in a gap with respect to the motor vehicle body 3, so that the operator can easily open the door leaf 1 and thus the entire motor vehicle door completely manually.
