Description

Elektromotorischer Antrieb für kraftfahrzeugtechnische Anwendungen  Electromotive drive for automotive applications
Beschreibung: Die Erfindung betrifft einen elektromotorischen Antrieb für kraftfahrzeugtechnische Anwendungen, insbesondere als Bestandteil einer Verriegelungseinrichtung einer elektrischen Anschlussvorrichtung für Elektro- oder Hybridkraftfahrzeuge, mit einem Elektromotor, ferner mit einem nachgeschalteten mehrstufigen Getriebe als Antriebselemente zur Beaufschlagung eines Stellelementes, beispielsweise eines Riegelelementes der Verriegelungseinrichtung, und mit einem die Antriebselemente einhausenden Antriebsgehäuse. The invention relates to an electromotive drive for automotive applications, in particular as part of a locking device of an electrical connection device for electric or hybrid motor vehicles, with an electric motor, further with a downstream multi-stage transmission as drive elements for acting on an actuating element, such as a locking element of the locking device, and with a drive housing housing the drive elements.
Elektromotorische Antriebe für kraftfahrzeugtechnische Anwendungen sind in großer Vielzahl aus der Praxis bekannt und werden beispielsweise in Verbindung mit Fensterhebern, Sitzverstellungen, Türspiegeln etc. eingesetzt. Darüber hinaus kennt man solche elektromotorischen Antriebe in Verbindung mit Kraftfahrzeugtürschlössern beispielsweise als Zuziehantriebe oder Verriegelungsantriebe. Den sämtlichen elektromotorischen Antrieben ist gemein, dass oftmals lineare Stellbewegungen abgebildet werden und die Versorgung eines an dieser Stelle eingesetzten Elektromotors mit Niedergleichspannung erfolgt. Electromotive drives for automotive applications are widely known in practice and are used for example in conjunction with window regulators, seat adjustments, door mirrors, etc. In addition, such electromotive drives are known in connection with motor vehicle door locks, for example as Zuziehantriebe or locking drives. Common to all electromotive drives is that often linear positioning movements are depicted and the supply of an electric motor used at this point takes place with low-voltage.
Solche elektromotorischen Antriebe kommen zunehmend auch als Bestandteile und in Verbindung mit Verriegelungseinrichtungen einer elektrischen Anschlussvorrichtung für Elektro- oder Hybridkraftfahrzeuge zum Einsatz. Beispiele für solche elektromotorischen Antriebe werden in der DE 10 2007 002 025 A1 vorgestellt. Hier dient der elektromotorische Antrieb als Bestandteil einer Verriegelungsvorrichtung oder Verriegelungseinrichtung dazu, einen Ladestecker gegenüber einer Ladesteckdose gegen Entnahme zu Verriegeln. Dazu arbeitet der bekannte Antrieb auf einen bewegbaren Riegel. Such electric motor drives are increasingly being used as components and in conjunction with locking devices of an electrical connection device for electric or hybrid motor vehicles. Examples of such electromotive drives are presented in DE 10 2007 002 025 A1. Here, the electric motor drive serves as part of a locking device or locking device to lock a charging plug against a charging socket against removal. For this purpose, the known drive works on a movable bolt.
Die lösbare Verankerung eines Ladesteckers in der Ladesteckdose mit Hilfe eines verfahrbaren Riegelelementes ist im Zusammenhang mit elektrischen Anschlussvorrichtungen für Elektro- oder Hybridkraftfahrzeuge von besonderer Bedeutung. Denn der Ladestecker stellt im Allgemeinen eine elektrische Verbindung zu einer Ladesäule als Bestandteil einer Ladeinfrastruktur dar. Hierdurch besteht die Möglichkeit, im Elektro- oder Hybridkraftfahrzeug vorhandene Akkumulatoren beispielsweise an einer Ladesäule als Bestandteil der Ladeinfrastruktur mit elektrischer Energie (wieder) aufzuladen. The releasable anchoring of a charging plug in the charging socket by means of a movable locking element is associated with electrical Connection devices for electric or hybrid motor vehicles of particular importance. Because the charging plug is generally an electrical connection to a charging station as part of a charging infrastructure. This makes it possible to (re) recharge existing batteries in the electric or hybrid motor vehicle, for example on a charging station as part of the charging infrastructure.
Da an dieser Stelle üblicherweise mit Hochspannung gearbeitet wird, ist es erforderlich, den Ladestecker in der Ladesteckdose mit Hilfe des verfahrbaren Riegelelementes lösbar zu verankern, um etwaige Gesundheitsgefahren von Benutzern fernzuhalten. Since work is usually carried out at this point with high voltage, it is necessary to releasably anchor the charging plug in the charging socket by means of the movable locking element to keep any health hazards of users.
Die lösbare Verriegelung des Ladesteckers gegenüber der Ladesteckdose ist zusätzlich noch von Bedeutung, als hierdurch im Allgemeinen eine eindeutige Zuordnung zwischen Benutzer und Ladesäule erfolgen kann, um die entnommene elektrische Energie benutzerabhängig abrechnen zu können. Eine solche Vorgehensweise wird beispielhaft in der WO 2010/149426 A1 beschrieben. Dadurch lässt sich insbesondere ein sogenannter „Stromklau" vermeiden. The releasable locking of the charging plug relative to the charging socket is additionally important, as this can generally be a clear assignment between the user and the charging station to account for the extracted electrical energy user dependent. Such a procedure is described by way of example in WO 2010/149426 A1. As a result, in particular a so-called "electricity jolt" can be avoided.
Beim gattungsbildenden Stand der Technik nach der CN 202695855 U ist insgesamt ein aus Kunststoff hergestelltes mehrteiliges Antriebsgehäuse vorgesehen, welches die einzelnen im Innern befindlichen Antriebselemente einhaust und vor Umwelteinflüssen schützt. Das bekannte Antriebsgehäuse weist auch teilweise Ausformungen auf, die als beispielsweise Aufnahmezapfen für hierauf angebrachte Lager bzw. Kugellager fungieren. Mit Hilfe der Lager bzw. Kugellager ist beispielsweise ein Zahnrad eines einem Elektromotor nachgeschalteten mehrstufigen Getriebes gelagert. Derartige Ausführungsformen verfügen einerseits über ein nicht unerhebliches Gewicht durch die zusätzlich vorgesehenen Lager insbesondere für das mehrstufige Getriebe. Andererseits ist die Herstellung und Montage aufwendig, weil die betreffenden Lager erst im Antriebsgehäuse angebracht werden müssen, bevor die einzelnen Antriebselemente hierin platziert werden können. Hier will die Erfindung insgesamt Abhilfe schaffen. In the generic state of the art according to CN 202695855 U, a multi-part drive housing made of plastic is provided in total, which houses the individual drive elements located in the interior and protects them from environmental influences. The known drive housing also has partial formations, which act as, for example, spigot for mounted thereon camp or ball bearings. With the help of bearings or ball bearings, for example, a gear of an electric motor downstream multi-stage transmission is mounted. On the one hand, such embodiments have a not inconsiderable weight due to the additionally provided bearings, in particular for the multi-stage transmission. On the other hand, the production and assembly is complicated because the bearing in question must first be mounted in the drive housing, before the individual drive elements can be placed therein. Here, the invention aims to provide a total remedy.
Der Erfindung liegt das technische Problem zugrunde, einen derartigen elektromotorischen Antrieb für kraftfahrzeugtechnische Anwendungen so weiter zu entwickeln, dass insgesamt das Gewicht verringert und die Kosten zur Herstellung und Montage gegenüber dem Stand der Technik reduziert sind. The invention is based on the technical problem of further developing such an electromotive drive for motor vehicle applications such that overall the weight is reduced and the costs for production and assembly compared to the prior art are reduced.
Zur Lösung dieser technischen Problemstellung ist ein elektromotorischer Antrieb für kraftfahrzeugtechnische Anwendungen im Rahmen der Erfindung dadurch gekennzeichnet, dass das Antriebsgehäuse mit innenseitigen und/oder randseitigen Ausformungen ausgerüstet ist, welche als unmittelbare Lagerstellen für einzelne oder sämtliche Antriebselemente fungieren bzw. solche Lagerstellen ausbilden. Das heißt, die Ausformungen weisen allgemein unmittelbare Lagerstellen für einzelne oder sämtliche Antriebselemente auf. To solve this technical problem, an electric motor drive for motor vehicle applications in the invention is characterized in that the drive housing is equipped with inside and / or marginal formations, which act as direct bearings for single or all drive elements or form such bearings. That is, the formations generally have immediate storage locations for individual or all drive elements.
Im Rahmen der Erfindung verfügt also das Antriebsgehäuse zunächst einmal über die innenseitigen und/oder randseitigen Ausformungen. Solche Ausformungen kennt grundsätzlich auch der den Ausgangspunkt bildende Stand der Technik nach der CN 202695855 U. Im Gegensatz hierzu dienen die fraglichen Ausformungen erfindungsgemäß jedoch dazu, unmittelbare Lagerstellen zu definieren oder solche unmittelbaren Lagerstellen aufzuweisen. In the context of the invention, therefore, the drive housing initially has on the inside and / or edge-side formations. In principle, such formations also know the state of the art according to CN 202695855 U. The contrary embodiments according to the invention, however, serve to define direct bearing points or to have such immediate bearing points.
Der Begriff„unmittelbare Lagerstelle" drückt in diesem Zusammenhang aus, dass das hierin gelagerte zugehörige Antriebselement direkt in der betreffenden Lagerstelle aufgenommen wird und zusätzliche zwischengeschaltete Lager weder vorgesehen noch vorhanden und erst recht nicht nötig sind. Hierbei geht die Erfindung von der Erkenntnis aus, dass die mit Hilfe der unmittelbaren Lagerstellen gelagerten Antriebselemente und die Ausformungen mit den betreffenden Lagerstellen im Regelfall aus gleichem oder ähnlichem Material hergestellt sind, typischerweise aus Kunststoff. Dadurch kommt es zwischen der unmittelbaren Lagerstelle aus Kunststoff in der zugehörigen Ausformung aus Kunststoff und dem darin beispielsweise beweglich gelagerten Antriebselement ebenfalls aus Kunststoff insgesamt und automatisch zu einer Gleitlagerung mit geringen Reibwerten (Kunststoff- Kunststoff). Als Folge hiervon wird der Einsatz zusätzlicher zwischengeschalteter Lager wie beim Stand der Technik entbehrlich. Dadurch kann der elektromotorische Antrieb nach der Erfindung besonders leicht aufgebaut werden, weil zusätzliche massive Lager entbehrlich sind. Außerdem sind die Herstellung und Montage deutlich kostenreduziert, weil die zusätzlichen Lager und ihre Montage entfallen. Hierin sind die wesentlichen Vorteile zu sehen. The term "immediate bearing point" in this context expresses that the associated drive element mounted therein is accommodated directly in the respective bearing point and additional interposed bearings are neither provided nor present, let alone being necessary the drive elements mounted with the aid of the direct bearing points and the formations with the relevant bearing points are generally made of the same or similar material, typically of plastic. This results in a total of between the immediate bearing of plastic in the associated molding made of plastic and the example movably mounted drive element also made of plastic and automatically to a sliding bearing with low coefficients of friction (plastic plastic). As a result, the use of additional intermediate bearings as in the prior art is dispensable. As a result, the electric motor drive according to the invention can be constructed particularly easily, because additional massive bearings are unnecessary. In addition, the production and installation are significantly reduced in cost, because the additional bearings and their assembly omitted. Here are the main benefits.
Nach vorteilhafter Ausgestaltung können die Ausformungen mit Lagerstellen für ortsfeste Antriebselemente ausgerüstet sein. Bei solchen ortsfesten Antriebselementen handelt es sich beispielhaft und meistens um den Elektro- motor des elektromotorischen Antriebes. Darüber hinaus lassen sich die Ausformungen auch mit Lagerstellen für bewegliche Antriebselemente ausrüsten. Bei den beweglichen Antriebselementen handelt es sich im Regelfall um Wellen, welche jeweils einzelne Stufen des mehrstufigen Getriebes definieren. Die Ausformungen sind vorteilhaft an das Antriebsgehäuse angeformt, und zwar darüber hinaus und bevorzugt einstückig. Als Folge hiervon sind die Ausformungen und das Antriebsgehäuse besonders vorteilhaft als einteiliges Kunststoffformteil ausgebildet. Dadurch erfolgt die Fertigung des Antriebsgehäuses zusammen mit den Ausformungen und folglich auch den Lagerstellen in oder an den Antriebselementen besonders einfach, schnell und kostengünstig. Zusätzliche Fertigungs- und Montageschritte sind also nicht erforderlich. According to an advantageous embodiment, the formations may be equipped with bearings for fixed drive elements. Such fixed drive elements are exemplary and usually the electric motor of the electromotive drive. In addition, the formations can also be equipped with bearings for movable drive elements. As a rule, the movable drive elements are shafts which in each case define individual stages of the multistage transmission. The formations are advantageously formed on the drive housing, moreover, and preferably in one piece. As a result, the formations and the drive housing are particularly advantageously formed as a one-piece plastic molded part. As a result, the production of the drive housing takes place in a particularly simple, fast and cost-effective manner together with the formations and consequently also the bearing points in or on the drive elements. Additional manufacturing and assembly steps are therefore not required.
Tatsächlich sind die Ausformungen meistens als Gehäuserippen des Antriebsgehäuses ausgelegt. Dadurch übernehmen die Ausformungen bzw. Gehäuse- rippen eine mehrfache Funktion. Zunächst einmal dienen sie zur Ausbildung der unmittelbaren Lagerstellen für einzelne oder sämtliche Antriebselemente. Darüber hinaus sorgen die Ausformungen bzw. Gehäuserippen zusätzlich für eine Versteifung des Antriebsgehäuses, was insofern von Bedeutung ist, als der beschriebene elektromotorische Antrieb als bevorzugter Bestandteil der Verriegelungseinrichtung für die elektrische Anschlussvorrichtung bei Elektro- oder Hybridkraftfahrzeugen oftmals erhöhten mechanischen Kräften ausgesetzt ist. In fact, the formations are usually designed as housing ribs of the drive housing. As a result, the formations or housing ribs assume a multiple function. First of all, they serve to form the immediate storage locations for individual or all drive elements. In addition, the formations or housing ribs additionally provide a stiffening of the drive housing, which is important in that as the described electric motor drive is exposed as a preferred component of the locking device for the electrical connection device in electric or hybrid vehicles often increased mechanical forces.
Das lässt sich darauf zurückführen, dass das Stellelement bzw. Riegelelement der Verriegelungseinrichtung oftmals in dem Antriebsgehäuse gelagert ist. Sobald das Riegelelement in eine Ausnehmung des Ladesteckers in verriegeltem Zustand eingetaucht ist und an dem Ladestecker bzw. einem hiermit verbundenen Kabel Zugkräfte angreifen, werden diese über das Riegelelement zugleich auch auf das Antriebsgehäuse übertragen. Dadurch kommt einer Versteifung des Antriebsgehäuses eine besondere Bedeutung zu. Dem trägt die Erfindung durch die als Gehäuserippen ausgebildeten Ausformungen Rechnung. Um die mehrfache Funktionalität besonders vorteilhaft zu realisieren und umzusetzen, verfügen die fraglichen Gehäuserippen im Allgemeinen über eine Ausdehnung in Quer- und/oder Längsrichtung, und zwar im Vergleich zur Axialrichtung des zugehörigen Antriebselementes. Das heißt, die Axialrichtung des Antriebselementes gibt die Längsrichtung vor. Da darüber hinaus und vorteilhaft die einzelnen Wellen des mehrstufigen Getriebes parallel zueinander angeordnet sind, verfügen die Ausformungen bzw. Gehäuserippen durchgängig über eine Ausdehnung in Querrichtung hierzu. Dadurch kommt es zugleich zur gewünschten Versteifung des Antriebsgehäuses mit Hilfe der Gehäuserippen, weil diese im Beispielfall in gleicher Richtung und beabstandet zueinander angeordnet sind. This can be attributed to the fact that the adjusting element or locking element of the locking device is often mounted in the drive housing. As soon as the locking element is immersed in a recess of the charging plug in the locked state and attack tensile forces on the charging plug or a cable connected thereto, these are transmitted via the locking element at the same time also on the drive housing. As a result, a stiffening of the drive housing is of particular importance. The invention contributes by the formed as a housing ribs formations bill. In order to realize and implement the multiple functionality particularly advantageous, the housing ribs in question generally have an extension in the transverse and / or longitudinal direction, in comparison to the axial direction of the associated drive element. That is, the axial direction of the drive element provides the longitudinal direction. Moreover, since the individual shafts of the multi-stage transmission are arranged in parallel and advantageously parallel to one another, the formations or housing ribs have an extension in the transverse direction throughout. This also leads to the desired stiffening of the drive housing with the help of the housing ribs, because they are arranged in the example in the same direction and spaced from each other.
Die Lagerstellen dienen typischerweise nicht nur zur Lagerung des betreffenden Antriebselementes. Sondern meistens übernehmen die Lagerstellen noch Zusatzfunktionen dergestalt, dass mit ihrer Hilfe das betreffende Antriebselement axial und/oder radial gesichert wird. The bearings are typically not only for storage of the relevant drive element. But usually the bearings take over additional functions such that with their help the relevant drive element is axially and / or radially secured.
Schlussendlich sind die Lagerstellen typischerweise in Montagerichtung der Antriebselemente jeweils geöffnet. Dadurch können die mit Hilfe der Lagerstellen gelagerten Antriebselement unschwer in der betreffenden Montagerichtung in die fragliche Lagerstellen eingesteckt oder auf diese aufgesteckt werden, so dass als Folge hiervon die Antriebselemente ihre bestimmungsgemäße Position einnehmen und sofort betriebsbereit sind. Weitere Montagemaßnahmen oder zusätzliche Lager sind ausdrücklich nicht erforderlich. Finally, the bearings are typically open in the mounting direction of the drive elements respectively. This can be done with the help of bearings stored drive element without difficulty in the relevant mounting direction inserted into the bearing points in question or are attached to this, so that as a result, the drive elements assume their intended position and are ready for use immediately. Further installation measures or additional bearings are expressly not required.
Die Lagerstellen dienen zur Versteifung und/oder Stabilisierung des Antriebsgehäuses. Hierdurch kann ein besonders stabiles Antriebsgehäuse bereitgestellt werden, was insbesondere angesichts der hohen Kräfte, welche die Verriegelungseinrichtung aushalten können muss, besonders vorteilhaft ist. The bearings serve to stiffen and / or stabilize the drive housing. In this way, a particularly stable drive housing can be provided, which is particularly advantageous in view of the high forces which the locking device must be able to withstand.
In Richtung auf eine einfache Montage zielen schließlich auch die Erfindungsmaßnahmen, wonach das Antriebsgehäuse im Allgemeinen zweiteilig mit einer die Ausformungen aufweisenden Unterschale und einer die Unterschale verschließenden Oberschale als Verschluss der Unterschale ausgebildet ist. Da die Unterschale mit den Ausformungen unmittelbar nach Einsetzen der betreffenden Antriebselemente betriebsfertig ist, kann der erfindungsgemäße elektromotorische Antrieb nach anschließender Montage der die Unterschale verschließenden Oberschale in oder an einer Karosserie des Elektro- oder Hybridkraftfahrzeuges montiert werden. Das alles gelingt einfach und mit gegenüber dem Stand der Technik deutlichen Kostenvorteilen. Finally, in the direction of a simple assembly, the inventive measures, according to which the drive housing is generally formed in two parts with a lower shell having the formations and an upper shell closing the lower shell, is designed as a closure of the lower shell. Since the lower shell with the formations is ready for operation immediately after insertion of the respective drive elements, the electromotive drive according to the invention can be mounted in or on a body of the electric or hybrid motor vehicle after subsequent assembly of the upper shell closing the lower shell. All of this succeeds simply and with significant cost advantages over the prior art.
Im Folgenden wird die Erfindung anhand von Zeichnungen, die lediglich ein bevorzugtes Ausführungsbeispiel darstellen, näher erläutert. Es zeigen: In the following the invention will be explained in more detail with reference to drawings, which represent only a preferred embodiment. Show it:

In der Übersichtsdarstellung nach der Fig. 3 ist ein elektromotorischer Antrieb für kraftfahrzeugtechnische Anwendungen dargestellt. Im Rahmen des Ausführungsbeispiels und nicht einschränkend stellt der elektromotorische Antrieb einen Bestandteil einer Verriegelungseinrichtung einer elektrischen Anschlussvorrichtung für Elektro- oder Hybridkraftfahrzeuge dar. Dazu ist in den Darstellungen nach den Fig. 2A bis 2C von dem fraglichen Elektro- oder Hybridkraftfahrzeug lediglich ansatzweise eine Karosserie 1 dargestellt. Die Karosserie 1 ist mit einer Ausnehmung 2 ausgerüstet. In the overview representation of FIG. 3, an electric motor drive for automotive applications is shown. Within the scope of the exemplary embodiment and not limitation, the electromotive drive is a component of a locking device of an electrical connection device for electric or hybrid motor vehicles. For this purpose, in the illustrations according to FIGS. 2A to 2C of the electric or hybrid motor vehicle in question only a partial body 1 is shown , The body 1 is equipped with a recess 2.
In der Ausnehmung 2 findet sich eine Ladesteckdose 3. Die Ladesteckdose 3 kann elektrisch und lösbar verriegelnd mit einem Ladestecker 4 gekoppelt werden, welcher dazu in die Ausnehmung 2 in der Karosserie 1 eingeführt und elektrisch verbindend mit der Ladesteckdose 3 gekoppelt wird. In the recess 2 there is a charging socket 3. The charging socket 3 can be coupled electrically and releasably locking with a charging connector 4, which is introduced into the recess 2 in the body 1 and electrically connected to the charging socket 3 is coupled.
Zu diesem Zweck verfügt der Ladestecker 4 über in der Fig. 1 lediglich angedeutete Steckkontakte 5, die in zugehörige Steckbuchsen 5' im Innern der Ladesteckdose 3 eingreifen. Selbstverständlich kann auch umgekehrt vorgegangen werden. In diesem Fall ist die Ladesteckdose 3 mit den SteckkontaktenFor this purpose, the charging connector 4 has in Fig. 1 only indicated plug contacts 5, which engage in associated sockets 5 'in the interior of the charging socket 3. Of course, the reverse can also be done. In this case, the charging socket 3 with the plug contacts
5 ausgerüstet, die in zugehörige Steckbuchsen 5' des Ladesteckers 4 lösbar eingreifen, was jedoch nicht dargestellt ist. Um den Ladestecker 4 mit der Ladesteckdose 3 lösbar zu verriegeln, ist ein verfahrbares Riegelelement 6 vorgesehen. Bei dem verfahrbaren Riegelelement5 equipped, which engage releasably in associated sockets 5 'of the charging plug 4, which is not shown. In order to releasably lock the charging plug 4 with the charging socket 3, a movable locking element 6 is provided. In the movable locking element
6 handelt es sich im Ausführungsbeispiel um einen Verriegelungsstift oder Verriegelungsstößel, welcher aus Kunststoff gefertigt ist. In alternativen Ausführungen kann das Riegelelement 6 auch aus einem Metall gefertigt sein. Nach dem Ausführungsbeispiel ist das Riegelelement 6 als Kunststoffspritzgussteil ausgelegt bzw. kann ein solches bilden. Das Riegelelement 6 greift zur lösbaren Verriegelung des Ladesteckers 4 gegenüber der Ladesteckdose 3 in eine zugehörige Ausnehmung 7 im Ladestecker 4 ein. Außerdem greift das Riegelelement 6 bei der Verriegelung des Ladesteckers 4 gegenüber der Ladesteckdose 3 zusätzlich in eine Ausnehmung 7' in der Ladesteckdose 3 ein. In der Fig. 2A ist der entriegelte Zustand des Ladesteckers 4 gegenüber der Ladesteckdose 3 dargestellt. Die Fig. 2C zeigt den verriegelten Zustand. In der Fig. 2B ist ein Übergang von der entriegelten zur verriegelten Stellung des Riegelelementes 6 wiedergegeben. 6 is in the embodiment to a locking pin or locking ram, which is made of plastic. In alternative embodiments, the locking element 6 may also be made of a metal. According to the embodiment, the locking element 6 is designed as a plastic injection molded part or can form such. The locking element 6 engages the releasable locking of the charging plug 4 relative to the charging socket 3 in an associated recess 7 in the charging plug 4 a. In addition, when the charging plug 4 is locked relative to the charging socket 3, the locking element 6 additionally engages in a recess 7 'in the charging socket 3. In Fig. 2A, the unlocked state of the charging plug 4 relative to the charging socket 3 is shown. Fig. 2C shows the locked state. In Fig. 2B, a transition from the unlocked to the locked position of the locking element 6 is shown.
Das Riegelelement 6 lässt sich gegenüber den beiden Ausnehmungen 7, 7' verfahren, um die Verriegelung zwischen dem Ladestecker 4 und der Lade- Steckdose 3 herzustellen respektive aufzuheben. Hierzu korrespondieren Bewegungen des Riegelelementes 6 in seiner Längsrichtung, wie dies durch einen Doppelpfeil in der Fig. 1 angedeutet ist. Für die Stellbewegungen des Riegelelementes 6 sorgt nach dem Ausführungsbeispiel der erfindungsgemäße elektromotorische Antrieb. Die Längsrichtung des Riegelelements 6 verläuft senkrecht zu einer Ebene, in der Wellen 9, 10, 1 1 des Antriebs angeordnet sind. Eine Dichtung 12 an einem Antriebsgehäuse 13 sorgt dafür, dass das Riegelelement 6 bei seinen Stellbewegungen gegenüber dem Antriebsgehäuse 13 abgedichtet ist. Der elektromotorische Antrieb wird in dem eigenen Antriebsgehäuse 13 aufgenommen und von dem Antriebsgehäuse 13 insgesamt eingehaust. Das gilt für sämtliche Antriebselemente, also einen Elektromotor 8 und ein dem Elektromotor 8 nachgeschaltetes mehrstufiges Getriebe. Da darüber hinaus das Riegelelement 6 im Antriebsgehäuse 13 gelagert ist, steht insgesamt eine einbaufertige Baugruppe bzw. ein Einbaumodul zur Verfügung. Selbstverständlich fallen unter die Erfindung auch Lösungen, bei welchen der Antrieb und die Ladesteckdose 3 in einem gemeinsamen Gehäuse aufgenommen werden. Dies ist in den Figuren jedoch nicht dargestellt. Der Antrieb umfasst einen Elektromotor 8, eine erste Welle 9, eine zweite Welle 10, eine dritte Welle 1 1 und einen Verriegelungshebel 1 19 an dem das Riegelelement 6 anliegt. Der Verriegelungshebel 1 19 wird über den Elektromotor 8 und die Wellen 9-1 1 in Bewegung versetzt, wodurch das Riegelelement 6 verfahren wird. Der Verriegelungshebel 19 wird dabei senkrecht zu einer Ebene, in der die Wellen 9-1 1 angeordnet sind, verfahren. Im Ausführungsbeispiel sind der Verriegelungshebel 1 19 und das Riegelelement 6 einstückig miteinander ausgeführt. The locking element 6 can be compared to the two recesses 7, 7 'procedure to establish the interlock between the charging connector 4 and the charging socket 3 respectively repeal. For this purpose, movements of the locking element 6 correspond in its longitudinal direction, as indicated by a double arrow in Fig. 1. For the adjusting movements of the locking element 6 provides according to the embodiment of the invention, the electric motor drive. The longitudinal direction of the locking element 6 extends perpendicular to a plane in which shafts 9, 10, 1 1 of the drive are arranged. A seal 12 on a drive housing 13 ensures that the locking element 6 is sealed in its positioning movements relative to the drive housing 13. The electromotive drive is received in the own drive housing 13 and housed by the drive housing 13 in total. This applies to all drive elements, that is to say an electric motor 8 and a multistage transmission connected downstream of the electric motor 8. In addition, since the locking element 6 is mounted in the drive housing 13, there is a total of one ready-to-install module or a built-in module available. Of course, fall under the invention also solutions in which the drive and the charging socket 3 are accommodated in a common housing. This is not shown in the figures. The drive comprises an electric motor 8, a first shaft 9, a second shaft 10, a third shaft 1 1 and a locking lever 1 19 on which the locking element 6 rests. The locking lever 1 19 is set via the electric motor 8 and the shafts 9-1 1 in motion, whereby the locking element. 6 is moved. The locking lever 19 is thereby moved perpendicular to a plane in which the shafts 9-1 1 are arranged. In the exemplary embodiment, the locking lever 1 19 and the locking element 6 are integrally formed with each other.
Das Riegelelement 6 weist eine gestufte Gestaltung mit einem Vorsprung 127 auf, so dass das Riegelelement 6 eine erste, höher gelegene Auflagefläche 129 auf dem Vorsprung 127 und eine zweite, niedriger gelegene, Auflagefläche 128 aufweist. Die relativen Angaben „höher gelegen" und „niedriger gelegen" beziehen sich hierbei auf einen Abstand zu einem gehäuseseitigen Ende des Riegelelements 6. Mit Hilfe der zwei Auflageflächen 128, 129 kann erfasst werden, ob der Ladestecker 4 ausreichend tief in die Ladesteckdose 3 eingeführt worden ist. Hierbei wird ausgenutzt, dass das Riegelelement 6 im Normalbetrieb, d.h. bei ausreichend tiefer Einführung des Ladesteckers 4 in die Ladesteckdose 3, sowohl die Ausnehmung 7 des Ladesteckers 4 durchgreift als auch in die Ausnehmung 7' der Ladesteckdose eingreift, um zu verriegeln. Die Ausnehmungen 7, 7' sind dabei in Bezug auf ihre Größe und Ausrichtung zueinander so gewählt, das im Normalbetrieb das Riegelelement 6 durch die Ausnehmung 7 in dem Ladestecker 4 durchgeführt wird und mit dem Vorsprung 127 in die Ausnehmung 7' der Ladesteckdose 3 eingeführt wird, wogegen die zweite Auflagefläche 128 an einer Oberfläche des Ladesteckers 3 zu liegen kommt und die Bewegung des Riegelelements 6 dadurch abgestoppt wird. Zusätzlich wird überwacht, wie lange der Elektromotor 8 des Antriebs vor der Abstoppung des Riegelelements 6 betrieben wurde, beispielsweise über eine Überwachung einer Anzahl von Drehungen einer der Wellen 9-10 oder über einen Stromverbrauch des Elektromotors 8. Dadurch kann festgestellt werden, ob der Normalbetrieb vorliegt. Ist der Ladestecker 3 nicht ausreichend tief eingeführt, kommt bereits die erste Auflagefläche 129 an dem Vorsprung 127 auf dem Ladestecker 3 zu liegen und das Riegelelement 6 wird bereits vorher abgestoppt. Zusätzlich kann eine dritte Situation erkannt werden, nämlich wenn der Ladestecker 3 gebrochen ist und somit eine sichere Verriegelung auch bei ausreichend tiefer Einführung nicht gewährleistet ist. In diesem Fall lässt sich das Riegelelement 6 tiefer als im Normalbetrieb einführen. Der Antrieb bzw. elektromotorische Antrieb setzt sich aus einem Elektromotor 8 und einem Getriebe aus einer ersten Welle 9, einer zweiten Welle 10 und einer dritten Welle 1 1 zusammen. Die erste Welle 9 bildet eine Abtriebswelle des Elektromotors 8 und kämmt über eine Verzahnung 122, welche bevorzugt als Evoloid-Verzahnung ausgeführt ist, mit der zweiten Welle 10. Die zweite Welle 10 weist ebenfalls eine Verzahnung 123 auf, über die die zweite Welle 10 mit der dritten Welle 1 1 kämmt. Auch die Verzahnung 123 der zweiten Welle 10 kann als Evoloid-Verzahnung ausgeführt sein. Die Evoloid-Verzahnung stellt eine hohe bis sehr hohe Übersetzung von beispielsweise 1 :30, 1 :80, 1 :140 oder 1 :320 bei relativ kompaktem Raumbedarf zur Verfügung. Die dritte Welle 1 1 arbeitet nach dem Ausführungsbeispiel und nicht einschränkend über den Exzenter bzw. einen Zapfen 17 unter Berücksichtigung der Führung 14, 15 auf das Riegelelement 6 und die durch den Antrieb hervorgerufenen Stellbewegungen auf das Riegelele- ment 6 überträgt. The locking element 6 has a stepped design with a projection 127, so that the locking element 6 has a first, higher support surface 129 on the projection 127 and a second, lower, support surface 128. The relative indications "higher located" and "lower located" refer here to a distance to a housing-side end of the locking element 6. With the help of the two bearing surfaces 128, 129 can be detected whether the charging plug 4 has been sufficiently deep introduced into the charging socket 3 is. This exploits that the locking element 6 in normal operation, that is, when sufficiently low insertion of the charging plug 4 in the charging socket 3, both the recess 7 of the charging plug 4 passes through and engages in the recess 7 'of the charging socket to lock. The recesses 7, 7 'are selected with respect to their size and orientation to each other so that in normal operation, the locking element 6 is performed by the recess 7 in the charging plug 4 and is introduced with the projection 127 in the recess 7' of the charging socket 3 whereas the second bearing surface 128 comes to lie on a surface of the charging plug 3 and the movement of the locking element 6 is thereby stopped. In addition, it is monitored how long the electric motor 8 of the drive has been operated before stopping the locking element 6, for example by monitoring a number of rotations of one of the shafts 9-10 or by a power consumption of the electric motor 8. Thus it can be determined whether the normal operation is present. If the charging plug 3 is not inserted sufficiently deep, the first bearing surface 129 already comes to lie on the projection 127 on the charging plug 3 and the locking element 6 is already stopped beforehand. In addition, a third situation can be detected, namely when the charging plug 3 is broken and thus a secure locking is not guaranteed even with sufficiently deep introduction. In this case, the locking element 6 can be inserted deeper than in normal operation. The drive or electromotive drive is composed of an electric motor 8 and a transmission of a first shaft 9, a second shaft 10 and a third shaft 1 1 together. The first shaft 9 forms an output shaft of the electric motor 8 and meshes via a toothing 122, which is preferably designed as Evoloid toothing, with the second shaft 10. The second shaft 10 also has a toothing 123 through which the second shaft 10 with the third wave 1 1 meshes. Also, the teeth 123 of the second shaft 10 may be designed as Evoloid toothing. The Evoloid gearing provides a high to very high ratio of, for example, 1: 30, 1: 80, 1: 140 or 1: 320 in a relatively compact space requirement. The third wave 1 1 operates according to the embodiment and not limiting on the eccentric or a pin 17, taking into account the guide 14, 15 on the locking element 6 and the actuating movements caused by the drive on the locking element 6 transmits.
Die dritte Welle 1 1 weist neben einer ersten Verzahnung 124, die mit der Verzahnung 123 der zweiten Welle kämmt, eine zweite Verzahnung 125 auf, die an einem der ersten Verzahnung 124 gegenüberliegenden Ende der dritten Welle 1 1 angeordnet ist. Die zweite Verzahnung 125 dient zum Antrieb einer Schalterbetätigung 130, über die ein als Mikroschalter ausgeführter Sensor 16 betätigt wird. Mittels der Betätigung des Mikroschalters wird eine erfolgte Drehung der dritten Welle 1 1 erfasst. Der Mikroschalter erfasst hierüber, wie weit sich die dritte Welle 1 1 gedreht hat bzw. wie lange der Antrieb in Betrieb gewesen ist. The third shaft 1 1, in addition to a first toothing 124, which meshes with the toothing 123 of the second shaft, a second toothing 125 which is disposed on one of the first teeth 124 opposite end of the third shaft 1 1. The second toothing 125 serves to drive a switch actuation 130, via which a sensor 16 designed as a microswitch is actuated. By means of the actuation of the microswitch a completed rotation of the third shaft 1 1 is detected. The micro-switch detects hereby how far the third shaft 1 1 has rotated or how long the drive has been in operation.
Mit Hilfe des Antriebes vollführt das Riegelelement 6 Stellbewegungen gegenüber einer Führung 14, 15. Die Führung 14, 15 ist nach dem Ausführungsbeispiel zweiteilig ausgebildet und setzt sich im Wesentlichen aus einer ortsfesten Gehäusedurchführung 14 im Antriebsgehäuse 13 einerseits und einer bewegbaren AbStützung 15 andererseits als jeweils Führungsbestandteile 14, 15 zusammen. Die Gehäusedurchführung 14 und auch das Riegelelement 6 können mit jeweils korrespondierenden und im Detail nicht ausdrücklich dargestellten Längsführungsmitteln ausgerüstet sein. Bei den Längsführungsmitteln des Riegelelementes 6 kann es sich um in Längsrichtung verlaufende Stege als Führungsbestandteil oder auch eine in Längsrichtung verlaufende Nut handeln. Demgegenüber ist das Längsführungsmittel der Gehäusedurchführung 14 als korrespondierende und zu den in Längsrichtung verlaufenden Stegen des Riegelelementes 6 passende Nut ausgeführt. Sofern das Riegelelement 6 mit der in Längsrichtung verlaufenden Nut als Längsführungsmittel ausgebildet ist, empfiehlt es sich, die Gehäusedurchführung 14 mit einer in die entsprechende Nut eingreifenden Nase auszurüsten. Selbstverständlich sind auch Mischformen denkbar. Auf solche korrespondierenden Längsführungsmittel kann grundsätzlich auch für den Fall verzichtet werden, dass das Riegelelement 6 beispielsweise Ecken aufweist oder insgesamt eine mehreckige Gestaltung anstelle der im Ausführungsbeispiel realisierten Zylinderform besitzt. The guide 14, 15 is formed according to the embodiment of two parts and consists essentially of a stationary housing bushing 14 in the drive housing 13 on the one hand and a movable Abstützung 15 on the other hand as each guide components 14, 15 together. The housing bushing 14 and also the locking element 6 can be equipped with corresponding longitudinal guide means not expressly shown in detail. The longitudinal guide means of the locking element 6 may be longitudinally extending webs as a guiding component or also a groove extending in the longitudinal direction. In contrast, the longitudinal guide means of the housing passage 14 is designed as a corresponding and to the longitudinally extending webs of the locking element 6 matching groove. If the locking element 6 is formed with the groove running in the longitudinal direction as a longitudinal guide means, it is recommended to equip the housing bushing 14 with a nose engaging in the corresponding groove. Of course, hybrids are also conceivable. In principle, such corresponding longitudinal guide means can also be dispensed with in the event that the locking element 6 has, for example, corners or, overall, has a polygonal configuration instead of the cylindrical shape realized in the exemplary embodiment.
Das Längsführungsmittel bzw. die bewegbare Abstützung 15 ist im Ausführungsbeispiel an einer Abkröpfung einer Welle 1 1 des Antriebes 8 bis 1 1 vorgesehen. Tatsächlich verfügt die fragliche Welle 1 1 nach dem Ausführungsbeispiel über einen Zapfen 16, bei dem es sich im Rahmen der Darstellung um die Abkröpfung der Welle 1 1 handelt. The longitudinal guide means or the movable support 15 is provided in the exemplary embodiment at a bend of a shaft 1 1 of the drive 8 to 1 1. In fact, the wave in question has 1 1 according to the embodiment of a pin 16, which is in the context of the illustration to the bend of the shaft 1 1.
Das Riegelelement 6 inklusive der Führungen 14, 15 und der beschriebene elektromotorische Antrieb bilden insgesamt die zuvor bereits angesprochene Verriegelungseinrichtung für die elektrische Anschlussvorrichtung. Anstelle zur Beaufschlagung des Riegelelementes 6 kann der Elektromotor 8 zusammen mit dem nachgeschalteten mehrstufigen Getriebe auch zur Beaufschlagung eines anders ausgebildeten Stellelementes dienen, was in den Figuren jedoch nicht dargestellt ist. The locking element 6 including the guides 14, 15 and the electric motor drive described above form the previously already mentioned locking device for the electrical connection device. Instead of acting upon the locking element 6, the electric motor 8 together with the downstream multi-stage transmission can also be used to act on a differently configured control element, which is not shown in the figures, however.
Erfindungsgemäß ist das Antriebsgehäuse 13 zweiteilig ausgelegt. Tatsächlich setzt sich dieses im Wesentlichen aus einer Unterschale 13a und einer die Unterschale 13a verschließenden Oberschale 13b als Verschluss der Unterschale 13a zusammen (vgl. Fig. 3 und 4). Außerdem verfügt das Antriebsgehäuse 13 über innenseitige und/oder randseitige Ausformungen 21 . Die fraglichen Ausformungen 21 bilden unmittelbare Lagerstellen 17; 18, 19 für einzelne oder sämtliche Antriebselemente aus bzw. fungieren selbst als eine solche Lagerstelle 17; 18, 19. According to the invention, the drive housing 13 is designed in two parts. In fact, this essentially consists of a lower shell 13a and a lower shell 13a closing upper shell 13b as a closure of Lower shell 13a together (see Fig. 3 and 4). In addition, the drive housing 13 has inside and / or edge-side formations 21st The questionable formations 21 form immediate bearings 17; 18, 19 for individual or all drive elements from or act as such a bearing 17 itself; 18, 19.
Bei der fraglichen Lagerstelle 17 handelt es sich um eine solche, mit deren Hilfe im Ausführungsbeispiel ortsfeste Antriebselemente 8 im Innern des Antriebsgehäuses 13 gelagert werden können. Bei dem ortsfesten Antriebselement 8 handelt es sich vorliegend um den zuvor bereits beschriebenen Elektromotor 8. Dieser ist jeweils endseitig seines Gehäuses mit zylindrischen Vorsprüngen ausgerüstet, die in den zugehörigen Lagerstellen 17 für das genannte ortsfeste Antriebselement bzw. den Elektromotor 8 Platz finden und hierin aufgenommen werden. Die betreffende Lagerstelle 17 findet sich dabei in einer zugehörigen Ausformung 21 . Bei der Ausformung 21 handelt es sich wie auch bei anderen Ausformungen 21 insgesamt um Gehäuserippen, die im Ausführungsbeispiel nicht nur zur Lagerung der Antriebselemente dienen, sondern zusätzlich auch das Antriebsgehäuse 13 insgesamt versteifen. Neben den zuvor angesprochenen Lagerstellen 17 für ortsfeste Antriebselemente bzw. den Elektromotor 8 sind dann noch weitere Lagerstellen 18, 19 vorgesehen, die für die Lagerung von beweglichen Antriebselementen eingesetzt werden und hierzu dienen. Bei den beweglichen Antriebselementen 9 bis 1 1 handelt es sich im Ausführungsbeispiel um Wellen des dem Elektromotor 8 nachgeschalteten mehrstufigen Getriebes. In the bearing 17 in question is one such, with the aid of which fixed drive elements 8 can be stored in the interior of the drive housing 13 in the embodiment. In the present case, the stationary drive element 8 is the previously described electric motor 8. This is equipped at the end of its housing with cylindrical projections, which can be accommodated in the associated bearing points 17 for said fixed drive element or the electric motor 8 and accommodated therein , The bearing 17 in question is found in an associated shape 21st The shaping 21 is, as with other formations 21, a total of housing ribs which, in the exemplary embodiment, not only serve to support the drive elements, but additionally stiffen the drive housing 13 as a whole. In addition to the previously mentioned bearings 17 for fixed drive elements or the electric motor 8 then further bearings 18, 19 are provided, which are used for the storage of movable drive elements and serve this purpose. The movable drive elements 9 to 1 1 are in the exemplary embodiment to waves of the electric motor 8 downstream multi-stage transmission.
Tatsächlich ist an dieser Stelle eine Abtriebswelle 9 des Elektromotors 8 vorgesehen, die mit einer zweiten Stufe des mehrstufigen Getriebes mit zugehöriger Welle 10 über ein Zahnrad kämmt. Die Welle 10 ist wiederum mit einer weiteren abtriebsseitigen Welle 1 1 gekoppelt. Die Welle 1 1 verfügt über die Abkröpfung bzw. den Zapfen 16 und folglich einen Exzenter. Der Zapfen 16 greift in die Abstützung 15 als Führungsbestandteil der zuvor bereits angesprochenen Führung 14, 15 für das Riegelelement 6 ein. Die einzelnen Wellen sind jeweils parallel zueinander angeordnet. Außerdem sind die einzelnen Wellen und zugehörige Zahnräder im Ausführungsbeispiel vorteilhaft aus Kunststoff hergestellt. Gleiches gilt für das Antriebsgehäuse 13. Da darüber hinaus die als Gehäuserippen ausgeführten Ausformungen 21 an das Antriebsgehäuse 13 bevorzugt einstückig angeformt sind und darüber hinaus die Ausformungen 21 und das Antriebsgehäuse 13 insgesamt ein einteiliges Kunststoffformteil bilden, lassen sich die beweglichen Antriebselemente unmittelbar mit den zugehörigen Lagerstellten 18, 19 koppeln. Dazu sind die sämtlichen Lagerstellen 17; 18, 19 in Montagerichtung der Antriebselemente 8 bis 1 1 jeweils geöffnet, nach dem Ausführungsbeispiel nach oben hin in der Blickrichtung eines Betrachters bei Aufsicht auf die Unterschale 13a nach der Fig. 3. Dadurch lassen sich die Antriebselemente 8 bis 1 1 von oben her in die fraglichen Lagerstellen 17; 18, 19 einsetzen und sind die Antriebselemente im Anschluss hieran unmittelbar einsatzbereit und zugleich einwandfrei gelagert. In fact, an output shaft 9 of the electric motor 8 is provided at this point, which meshes with a second stage of the multi-stage transmission with associated shaft 10 via a gear. The shaft 10 is in turn coupled to a further output-side shaft 1 1. The shaft 1 1 has the bend or the pin 16 and consequently an eccentric. The pin 16 engages in the support 15 as a guiding component of the previously mentioned guide 14, 15 for the locking element 6 a. The individual shafts are each arranged parallel to one another. In addition, the individual shafts and associated gears are advantageously made in the embodiment of plastic. The same applies to the drive housing 13. Moreover, since the formations 21 designed as housing ribs are preferably integrally formed on the drive housing 13 and, moreover, the formations 21 and the drive housing 13 form a one-piece plastic molded part as a whole, the movable drive elements can be directly connected to the associated bearing points Pair 18, 19. For this purpose, all the bearings 17; 18, 19 in the mounting direction of the drive elements 8 to 1 1 respectively open, according to the embodiment in the direction of an observer in the direction of view of the lower shell 13 a of FIG. 3. This allows the drive elements 8 to 1 1 from above in the bearings in question 17; 18, 19 and the drive elements are then immediately ready for use and at the same time stored properly.
Durch die Auslegung der Wellen und folglich der beweglichen Antriebselemente aus Kunststoff und gleichzeitig die Tatsache, dass die Ausformungen bzw. Gehäuserippen 21 ebenfalls aus Kunststoff ausgebildet sind, werden in diesem Zusammenhang insgesamt Gleitlager im Bereich der zugehörigen Lagerstellen 18, 19 beobachtet, die besonders reibungsarm aufgrund der Reibung„Kunststoff- Kunststoff" arbeiten. Gleichzeitig ist ein dauerhafter Betrieb gewährleistet. Denn die Lagerstellen 18, 19 für die beweglichen Antriebselemente 9 bis 1 1 sind ebenso wie die Lagerstellen 17 für die ortsfesten Antriebselemente 8 jeweils im Querschnitt U-förmig und nach oben hin geöffnet in den Ausformungen bzw. Gehäuserippen 21 vorgesehen. Dadurch wird insgesamt die„Unmittelbarkeit" der Lagerstellen 17; 18, 19 realisiert. Due to the design of the shafts and consequently the movable drive elements made of plastic and at the same time the fact that the formations or housing ribs 21 are also formed of plastic, in this connection, a total of plain bearings in the area of the associated bearings 18, 19 are observed, the very low friction due The bearings "18, 19" for the movable drive elements 9 to 11 are just like the bearings 17 for the fixed drive elements 8 in each case in cross-section U-shaped and upwards opened in the moldings or housing ribs 21. As a result, the "immediacy" of the bearings 17; 18, 19 realized.
Die Gehäuserippen 21 weisen im Allgemeinen eine Ausdehnung in Querrichtung im Vergleich zur Axialrichtung des zugehörigen Antriebselementes 8 bis 1 1 auf, welche mit der in der Fig. 3 angedeuteten Längsrichtung L zusammenfällt. Da im Ausführungsbeispiel die Wellen 9 bis 1 1 parallel zueinander und parallel zum Elektromotor 8 angeordnet sind, fällt die Axialrichtung mit der in der Fig. 1 angedeuteten Längsrichtung L des Antriebsgehäuses 13 zusammen. Demgegenüber sind die Gehäuserippen 21 überwiegend quer zur Längsrichtung L orientiert und angeordnet. Auf diese Weise verfügen die Ausformungen bzw. Gehäuserippen 21 über eine beabstandete Anordnung in gleicher Richtung zueinander, nämlich überwiegend der Querrichtung im Vergleich zur Längsrichtung L, so dass sich hierdurch die zuvor bereits angesprochene Versteifung des Antriebsgehäuses 13 mit ihrer Hilfe erklärt. The housing ribs 21 generally have an extent in the transverse direction compared to the axial direction of the associated drive element 8 to 1 1, which coincides with the direction indicated in FIG. 3, the longitudinal direction L. Since in the exemplary embodiment the shafts 9 to 1 1 are arranged parallel to one another and parallel to the electric motor 8, the axial direction coincides with that in FIG. 1 indicated longitudinal direction L of the drive housing 13 together. In contrast, the housing ribs 21 are predominantly oriented and arranged transversely to the longitudinal direction L. In this way, the formations or housing ribs 21 have a spaced arrangement in the same direction to each other, namely predominantly the transverse direction in comparison to the longitudinal direction L, so that this explains the previously mentioned stiffening of the drive housing 13 with their help.
Die jeweiligen Lagerstellen 17; 18, 19 können sowohl zur Axial- als auch Radialsicherung des betreffenden Antriebselementes 8 bis 1 1 eingerichtet sein. Das gilt insbesondere für die Lagerstelle 18 in der in etwa mittigen Gehäuserippe 21 , mit deren Hilfe eine separate und nicht ausdrücklich gekennzeichnete zusätzliche Welle an einer Kurbel 20 im Innern des Antriebsgehäuses 13 gelagert wird. Die Kurbel 20 stellt einen Bestandteil einer Notentriegelung dar. Mit Hilfe der Notentriegelung respektive der Kurbel 20 kann bei einem Ausfall des Elektromotors 8 das mehrstufige Getriebe dennoch so beaufschlagt werden, dass hierdurch das Riegelelement 6 in seine zurückgezogene Position überführt wird und hierdurch aus der Ausnehmung 7 im Ladestecker 4 und auch gegenüber der Ausnehmung 7' in der Ladesteckdose 3 freikommt. Dadurch kann der Ladestecker 4 gegenüber der Ladesteckdose 3 auch bei ausgefallenem Antrieb notentriegelt werden. Die dritte Welle 1 1 weist eine dritte Verzahnung 126, die in dem Ausführungsbeispiel als einzelner Zahn ausgeführt ist. Bei der Notbetätigung wirkt die Notentriegelungseinrichtung, die mittels der Kurbel 20 angetrieben werden kann, auf die dritte Verzahnung 126 ein, um die dritte Welle 1 1 und somit den gesamten Antrieb zurückzustellen. The respective bearings 17; 18, 19 may be configured for both axial and radial securing of the relevant drive element 8 to 1 1. This is especially true for the bearing 18 in the approximately central housing rib 21, with the help of a separate and not explicitly marked additional shaft is mounted on a crank 20 in the interior of the drive housing 13. The crank 20 is a part of an emergency release. With the help of the emergency release respectively the crank 20, the multi-stage transmission can nevertheless be acted upon in case of failure of the electric motor 8, thereby the latch member 6 is transferred to its retracted position and thereby from the recess. 7 in the charging plug 4 and also with respect to the recess 7 'in the charging socket 3 is released. As a result, the charging plug 4 can be unlocked relative to the charging socket 3 even if the drive has failed. The third shaft 1 1 has a third toothing 126, which is designed in the embodiment as a single tooth. In the emergency operation, the emergency unlocking device, which can be driven by means of the crank 20, acts on the third toothing 126 in order to reset the third shaft 11 and thus the entire drive.
Wie bereits erläutert, ist das Antriebsgehäuse 13 vorteilhaft zweiteilig ausgebildet. Dazu verfügt das Antriebsgehäuse 13 über die in der Fig. 3 primär dargestellte Unterschale 13a, welche die Ausformungen 21 mit den zugehörigen Lagerstellen 17; 18, 19 aufweist und diese definiert. Die Unterschale 13a lässt sich wie beschrieben in der Montagerichtung mit den Antriebselementen 8 bis 1 1 bestücken. Anschließend wird die in der Fig. 4 dargestellte Oberschale 13b auf die bestückte Unterschale 13a aufgesetzt und dadurch das Antriebsgehäuse 13 geschlossen. Da der elektromotorische Antrieb 8 bis 1 1 mit dem Riegelelement 6 kombiniert ist und insgesamt in dem Antriebsgehäuse 13 aufgenommen wird, steht eine einbaufertige Baugruppe bzw. ein Modul für die unmittelbare Anbringung in oder an der Karosserie 1 zur Verfügung. Hierbei muss natürlich sichergestellt werden, dass ein Bediener die Kurbel 20 bei einer etwaigen und erforderlichen Notentriegelung erreichen und beaufschlagen kann. Zumindest die Kurbel 20 muss also von außen her grundsätzlich zugänglich sein. As already explained, the drive housing 13 is advantageously formed in two parts. For this purpose, the drive housing 13 has the subshell 13a, which is shown primarily in FIG. 3, which supports the formations 21 with the associated bearing points 17; 18, 19 and defines this. The lower shell 13a can be equipped as described in the mounting direction with the drive elements 8 to 1 1. Subsequently, the upper shell 13b shown in FIG. 4 is placed on the stocked lower shell 13a and thereby the drive housing 13th closed. Since the electromotive drive 8 to 1 1 is combined with the locking element 6 and is accommodated in total in the drive housing 13, a ready-to-install assembly or a module for direct attachment in or on the body 1 is available. In this case, of course, it must be ensured that an operator can reach and apply the crank 20 in the event of a possible and necessary emergency release. At least the crank 20 must therefore be accessible from the outside in principle.
