Description

Die Erfindung betrifft einen Türaußengriff, insbesondere für Fahrzeuge. Solche Türgriffe enthalten heutzutage häufig elektronische Bauteile, welche z.B. der Identifizierung einer Zugangsberechtigung eines Benutzers zum Fahrzeug dienen. Schwierig bei diesen Türaußengriffen ist es, dass einerseits der elektrische Kontakt dieser elektronischen Bauteile zur Fahrzeugelektronik hergestellt werden muss. Andererseits ist es jedoch auch wichtig, die im Türaußengriff befindlichen elektronischen Bauteile vor Feuchtigkeit zu schützen.The invention relates to an outside door handle, in particular for vehicles. Such door handles today often include electronic components which are e.g. to identify a user's access authorization to the vehicle. Difficult with these exterior door handles is that on the one hand the electrical contact of these electronic components to the vehicle electronics must be made. On the other hand, it is also important to protect the outside of the door located electronic components from moisture.

US2007/216174A1 offenbart einen Türaußengriff für Fahrzeuge mit einem bügelförmigen wenigstens bereichsweise hohlen Handgriff, der zwei Griffhaken aufweist. Die Griffhaken dienen zur Befestigung des Handgriffs an der Fahrzeugtür. Innerhalb eines Hohlraums des Türaußengriffs sind elektronische Bauteile angeordnet, welche Leitungen aufweisen, die mit der Elektronik des Fahrzeugs verbindbar sind. Der Handgriff weist zumindest eine etwa U-förmige Griffschale auf, deren Raum zur Aufnahme der elektronischen Komponenten dienen kann, sowie eine Blende, welche zum Verschließen der Öffnung der Griffschale dient. Die elektronischen Bauteile sind in der Griffschale wasserdicht vergossen. US2007 / 216174A1 discloses an outside door handle for vehicles with a bow-shaped at least partially hollow handle, which has two handle hooks. The handle hooks are used to attach the handle to the vehicle door. Within a cavity of the outside door handle electronic components are arranged, which have lines that are connectable to the electronics of the vehicle. The handle has at least one approximately U-shaped handle shell, whose space can be used to hold the electronic components, as well as a screen, which serves to close the opening of the handle. The electronic components are sealed watertight in the handle shell.

Aus der EP1035276A2 und der EP1052349A1 ist allgemein bekannt, Leitungen im Griffhaken unlösbar zu verbinden.From the EP1035276A2 and the EP1052349A1 It is generally known to permanently connect cables in the grip hook.

Die DE 102 56 842 A1 schlägt hierzu vor, die elektronischen Bauteile vorzuvergießen und dann mit einem der Griffhaken die vorvergossene Elektronik in den Handgriff des Türaußengriffs einzuführen und den Handgriff mit dem Griffhaken zu verschließen. Nachteilig hierbei ist es jedoch, dass Feuchtigkeit so in den Innenraum des Handgriffes gelangen kann. Wenn die elektronischen Bauteile beispielsweise mehrere kapazitive Sensoren vorsehen, kann es sein, dass diese durch einen Feuchtigkeitsfilm miteinander verbunden werden und dadurch nicht mehr funktionieren oder zumindest nicht die gewünschten Funktionen ausführen.The DE 102 56 842 A1 proposes to vorzuvergießen the electronic components and then introduce the pre-molded electronics in the handle of the outside door handle with one of the handle hooks and to close the handle with the handle hook. The disadvantage here, however, is that moisture can get into the interior of the handle so. For example, if the electronic components provide multiple capacitive sensors, they may be connected together by a moisture film and thereby cease to function, or at least not perform the desired functions.

In der EP 1 212 502 wird ein Türaußengriff gezeigt, bei welchem die Elektronik im Handgriff komplett mit einer Vergussmasse vergossen wird. Hierdurch ergeben sich keine Probleme mehr mit Undichtigkeiten. Allerdings muss in dem Handgriff eine Bohrung für die elektrischen Anschlussleitungen vorgesehen werden, um die elektronischen Bauteile an die Fahrzeugelektronik anzuschließen und mit dieser zu verbinden. Die Leitungen werden zumeist an einem der Griffhaken entlang geführt. Jedoch sind sie dadurch quasi freiliegend und können beschädigt werden.In the EP 1 212 502 an outside door handle is shown in which the electronics in the handle is completely encapsulated with a potting compound. As a result, there are no more problems with leaks. However, a hole for the electrical connection lines must be provided in the handle to the connect electronic components to the vehicle electronics and connect to this. The cables are usually guided along one of the handle hooks. However, they are thus virtually exposed and can be damaged.

Aufgabe der Erfindung ist es daher, einen Türaußengriff vorzusehen, bei welchem die elektronischen Bauteile vor Feuchtigkeiten vollständig geschützt werden, andererseits die elektrischen Anschlussleitungen für die elektronischen Bauteile nicht frei zugänglich sind. Dies wird erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst, denen folgende besondere Bedeutung zukommt.The object of the invention is therefore to provide an outside door handle, in which the electronic components are completely protected from moisture, on the other hand, the electrical leads for the electronic components are not freely accessible. This is inventively achieved by the characterizing features of claim 1, which have the following special significance.

Die elektrischen Leitungen sind mit einem der Griffhaken unlösbar verbunden. Dies kann bevorzugterweise durch Vergießen geschehen oder aber auch dadurch, dass die Leitungen von dem Griffhakenmaterial bei der Herstellung des Griffhakens bereits umspritzt werden. Mittels dieses Griffhakens können die Leitungen dann durch das Türaußenblech ins Innere geführt werden, um dort eine Kontaktierung mit der Fahrzeugelektronik herzustellen.The electrical lines are permanently connected to one of the handle hooks. This can preferably be done by casting or else in that the lines are already encapsulated by the handle hook material in the manufacture of the handle hook. By means of this handle hook, the lines can then be passed through the door outer panel into the interior, there to make a contact with the vehicle electronics.

Um die Kontaktierung mit der Fahrzeugelektronik zu vereinfachen, kann der Griffhaken an seinem anderen Ende einen Stecker aufweisen, wobei die Fahrzeugelektronik günstigerweise einen Gegenstecker besitzt, so dass die Kontaktierung durch Zusammenstecken des Steckers mit dem Gegenstecker stattfinden kann.In order to simplify the contact with the vehicle electronics, the handle hook may have at its other end a plug, the vehicle electronics conveniently has a mating connector, so that the contact can take place by mating the plug with the mating connector.

An seinem einen Ende kann der Griffhaken Anschlussstellen aufweisen, welche mit Gegenanschlussstellen der elektronischen Bauteile verbindbar sind. Je nach Anwendungsfall kann es sinnvoll sein, die Anschlussstellen und die Gegenanschlussstellen miteinander zu verlöten, um einen besonders sicheren Kontakt herzustellen.At one end of the handle hooks may have connection points, which are connectable to counter-connection points of the electronic components. Depending on the application, it may be useful to solder the connection points and the mating connection points together in order to establish a particularly secure contact.

Der Griffhaken und die Griffschale können zweiteilig ausgebildet werden. In diesem Fall ist es besonders vorteilhaft, die Anschlussstellen des Griffhakens und die Gegenanschlussstellen der elektronischen Bauteile zunächst miteinander zu kontaktieren und dann den Griffhaken und die elektronischen Bauteile als Baugruppe in die Griffschale einzubringen. Besonders vorteilhaft ist es, diese Baugruppe dann von oben in die Öffnung der Griffschale einzubringen und dort zu positionieren. Zwischen dem Griffhaken und der Griffschale kann dann bevorzugterweise eine Labyrinthdichtung vorgesehen sein, welche dafür sorgt, dass keine Feuchtigkeit in den Hohlraum des Türaußengriffes gelangen kann.The handle hook and the handle shell can be formed in two parts. In this case, it is particularly advantageous, the connection points of the handle hook and the First to contact each other with counter-connection points of the electronic components and then to introduce the handle hook and the electronic components as an assembly in the handle shell. It is then particularly advantageous to introduce this assembly from above into the opening of the handle shell and to position it there. Between the handle hook and the handle shell then preferably a labyrinth seal can be provided, which ensures that no moisture can get into the cavity of the outside door handle.

Es ist selbstverständlich auch möglich, den einen und/oder den anderen Griffhaken mit der Griffschale einstückig auszubilden. Die an dem einen Griffhaken vorgesehenen Anschlussstellen können dann so ausgebildet und angeordnet werden, dass beim Einbringen der elektronischen Bauteile in die Griffschale eine automatische Kontaktierung der Gegenanschlussstellen mit den Anschlussstellen erfolgt. Hierdurch ist eine besonders einfache Montage des Türaußengriffs möglich. Anschließend kann dann das Vergießen erfolgen.It is of course also possible to form the one and / or the other handle hook with the handle shell in one piece. The connection points provided on the one grip hook can then be designed and arranged in such a way that, when the electronic components are introduced into the grip shell, the contact points are automatically contacted with the connection points. As a result, a particularly simple installation of the outside door handle is possible. Then then the casting can be done.

Die auf der Griffschale aufgebrachte Blende kann mit dieser auf vielerlei Arten verbunden werden, beispielsweise durch Verkleben, Verschweißen, Verclipsen, Verrasten, Verschrauben oder eine andere lösbare Verbindung.The applied on the handle shell panel can be connected to this in many ways, for example by gluing, welding, clipping, latching, screwing or other releasable connection.

Besonders vorteilhaft ist es, wenn die Vergussmasse, welche zum Vergießen der elektronischen Bauteile im Raum der Griffschale dient, den Raum auffüllt bis zu einem Füllstand der knapp unterhalb der Oberkante der Griffschale liegt. Hierdurch wird sichergestellt, dass die elektronischen Bauteile allesamt sicher vergossen sind, andererseits jedoch keine Vergussmasse überläuft. Besonders bewährt hat sich ein Füllstand der ungefähr 1 mm oder weniger unterhalb der Oberkante der Griffschale liegt.It when the potting compound, which serves for potting the electronic components in the space of the handle shell, the space fills up to a level of just below the upper edge of the handle is particularly advantageous. This ensures that the electronic components are all safely shed, on the other hand, however, does not overflow potting compound. Has proven particularly useful is a level of about 1 mm or less below the upper edge of the handle.

Die Vergussmasse selbst kann ein Gießharz, ein Wachs oder auch eine Zweikomponentenvergussmasse sein. Hier bieten sich alle im Stand der Technik bekannten Vergussmassen an.The potting compound itself may be a casting resin, a wax or a two-component potting compound. Here are all known in the prior art casting compounds.

Je nach Anwendungsfall kann ein Taster an der Außenseite des Handgriffes vorgesehen sein. In diesem Fall wird zunächst der Taster an der Griffschale vormontiert, dann die elektronischen Bauteile hineingebracht und zum Schluss vergossen und die Blende montiert. Es ist selbstverständlich auch möglich, statt des Tasters Sensoren mit beispielsweise außenliegenden Sensorflächen vorzusehen.Depending on the application, a button may be provided on the outside of the handle. In this case, the button is first preassembled on the handle shell, then brought in the electronic components and finally cast and mounted the panel. It is of course also possible to provide sensors with, for example, external sensor surfaces instead of the button.

In Fig. 1 ist ein erfindungsgemäßer Türaußengriff 10 dargestellt. Dieser weist einen Handgriff 11 auf, welcher aus einer Griffschale 12 und einer Blende 14 besteht. Des Weiteren ist an der Außenseite 18 des Handgriffes 11 noch ein Taster 50 vorgesehen.In Fig. 1 an inventive outside door handle 10 is shown. This has a handle 11, which consists of a handle shell 12 and a diaphragm 14. Furthermore, a button 50 is provided on the outer side 18 of the handle 11.

Den inneren Aufbau des Türaußengriffs 10 und des Handgriffes 11 ist aus den Fig. 2 bis 4 näher ersichtlich, welche allesamt Schnittzeichnungen des Türaußengriffs 10 aus Fig. 1 darstellen.The internal structure of the outside door handle 10 and the handle 11 is from the Fig. 2 to 4 can be seen in more detail, which are all sectional drawings of the outside door handle 10 Fig. 1 represent.

Fig. 2 zeigt dabei den Türaußengriff 10 in Draufsicht im Schnitt. Man erkennt die elektronischen Bauteile 30, welche über die Gegenanschlussstellen 32 mit den Anschlussstellen 24 des einen Griffhakens 20 verbunden sind. Der eine Griffhaken 20 und die Griffschale 12 sind hier zweiteilig ausgebildet. Fig. 2 shows the outside door handle 10 in plan view in section. It can be seen the electronic components 30, which are connected via the mating connection points 32 with the connection points 24 of a handle hook 20. The one handle hook 20 and the handle shell 12 are here formed in two parts.

Während an dem einen Ende 22 des einen Griffhakens 20 die Anschlussstellen 24 angeordnet sind, ist am anderen Ende 23 des einen Griffhakens 20 der Stecker 25 befindlich. Dieser dient der Kontaktierung der elektronischen Bauteile 30 mit der Fahrzeugelektronik. Bei der Herstellung des einen Griffhakens 20 kann der Stecker bereits vorgefertigt sein und lediglich eingelegt und vom Material des einen Griffhakens 20 umspritzt werden. Es ist aber auch möglich, nur die Leitungen vorzusehen und bei der Herstellung des einen Griffhakens 20 diese so zu umspritzen, dass der Stecker 25 mit angeformt wird.While at one end 22 of a handle hook 20, the connection points 24 are arranged at the other end 23 of a handle hook 20 of the connector 25 is located. This serves for contacting the electronic components 30 with the vehicle electronics. In the production of a handle hook 20, the plug can be pre-fabricated and only inserted and overmolded by the material of a handle hook 20. But it is also possible to provide only the lines and in the production of a handle hook 20 to encase them so that the plug 25 is molded with.

Im Gegensatz zum einen Griffhaken 20 ist der andere Griffhaken 21 einstückig mit der Griffschale 12 ausgeführt.In contrast to a handle hook 20, the other handle hook 21 is formed integrally with the handle shell 12.

Zwischen dem einen Griffhaken 20 und der Griffschale 12 ist eine Labyrinthdichtung 26 ausgebildet, die einerseits der Abdichtung des Raumes 13 der Griffschale 12 vor dem Eindringen von Verschmutzungen und Feuchtigkeit dient, andererseits aber auch dafür da ist, dass während des Vergießens der elektronischen Bauteile 30 in der Griffschale 12 keinerlei Vergussmasse 40 nach außen austreten kann. Zur weiteren Befestigung des einen Griffhakens 20 an der Griffschale 12 ist noch, wie hier erkennbar, ein Befestigungsmittel, hier eine Schraube, vorgesehen.Between the one handle hook 20 and the handle shell 12, a labyrinth seal 26 is formed, on the one hand serves to seal the space 13 of the handle shell 12 against the ingress of dirt and moisture, but on the other hand is there that during the casting of the electronic components 30 in the grip 12 can escape any potting compound 40 to the outside. For further attachment of a handle hook 20 on the handle shell 12 is still, as can be seen here, a fastening means, here a screw provided.

Die Kontaktierung der Anschlussstellen 24 und der Gegenanschlussstellen 32 kann automatisch erfolgen oder auch durch Crimpen oder Löten herbeigeführt werden.The contacting of the connection points 24 and the counter-connection points 32 can be done automatically or be brought about by crimping or soldering.

Den inneren Aufbau nach dem Einfüllen der Vergussmasse 40 in die Griffschale 12 erkennt man aus den Fig. 3 und 4. Hier ist erkennbar, dass der Füllstand 41 der Vergussmasse 40 bis knapp, hier ca. 1 mm, unterhalb der Öffnung 15 der Griffschale 12 reicht. Dieser Füllstand 41 ist besonders günstig, da einerseits die elektronischen Bauteile 30 sicher und vollständig vergossen und somit sowohl sicher in der Griffschale 12 gelagert werden als auch vor Feuchtigkeit und Verschmutzungen geschützt sind. Andererseits kann aber auch keine Vergussmasse 40 beim Vergießen über den Rand der Griffschale 12 überschwappen und somit die Griffschale 12 verschmutzen.The inner structure after filling the potting compound 40 in the handle shell 12 can be seen from the 3 and 4 , Here it can be seen that the level 41 of the potting compound 40 to scarce, here about 1 mm, below the opening 15 of Handle shell 12 is sufficient. This level 41 is particularly favorable, since on the one hand, the electronic components 30 safely and completely potted and thus both safely stored in the handle shell 12 and are protected from moisture and dirt. On the other hand, however, no potting compound 40 spill over the edge of the handle shell 12 during casting and thus contaminate the handle shell 12.

Nachdem der Vergießvorgang abgeschlossen ist, wird die Blende 14 montiert, welche die Öffnung 15 der Griffschale 12 vollständig überdeckt.After the Vergießvorgang is completed, the aperture 14 is mounted, which completely covers the opening 15 of the handle shell 12.

Fig. 5 zeigt eine weitere vorteilhafte Ausgestaltung der Erfindung in einer Darstellung gemäß Fig. 3. Der erfindungsgemäße Türaußengriff 10 umfasst hier den Handgriff 11, welcher ebenfalls aus einer Griffschale 12 und einer Blende 14 besteht. Der eine Griffhaken 20 und die Griffschale 12 sind zweiteilig ausgebildet. Zwischen diesen beiden Bauteilen erkennt man die labyrinthartige Dichtung 26. Diese dient, wie bereits erwähnt, der Dichtigkeit des Handgriffes 11 und zwar sowohl beim Einfüllen der Vergussmasse 40 in die Griffschale 12 als auch im Betrieb des erfindungsgemäßen Türaußengriffes 10 bezüglich des Eindringens von Feuchtigkeit und Verschmutzungen. Fig. 5 shows a further advantageous embodiment of the invention in a representation according to Fig. 3 , The door outer handle 10 according to the invention here comprises the handle 11, which also consists of a handle shell 12 and a diaphragm 14. The one handle hook 20 and the handle shell 12 are formed in two parts. This serves, as already mentioned, the tightness of the handle 11, both during filling of the potting compound 40 in the handle shell 12 and during operation of the outside door handle 10 according to the invention with respect to the penetration of moisture and dirt ,

Das eine Ende 22 des einen Griffhakens 20, welches auch die Anschlussstellen 24 aufweist, ist gebogen ausgeführt. Hierdurch bilden die Anschlussstellen 24 eine in etwa horizontale Ebene. Bei der Montage des Türaußengriffs 10 kann so zunächst der eine Griffhaken 20 mit der Griffschale 12 montiert werden. Danach können dann die elektronischen Bauteile 30, welche hier eine Leiterplatte, die mit weiteren Bauelementen bestückt ist, umfassen, in den Raum 13 der Griffschale 12 eingebracht werden und die Kontaktierung der Anschlussstellen 24 des einen Griffhakens 20 mit den Gegenanschlussstellen 32 der elektronischen Bauteile 30 kann in einfacher Weise erfolgen. Diese Kontaktierung kann auch hier beispielsweise durch Verlöten oder Crimpen herbeigeführt werden. Alternativ können jedoch die Anschlussstellen 24 und die Gegenanschlussstellen 32 auch bei diesem Ausführungsbeispiel so ausgebildet sein, dass die Kontaktierung automatisch beim Positionieren der elektronischen Bauteile 30 im Raum 13 der Griffschale 12 erfolgt. Besonders vorteilhaft bei der hier dargestellten Ausführungsform ist es, dass die elektronischen Bauteile 30 nicht mit dem einen Griffhaken 20 vormontiert werden müssen. So ist das Risiko einer Beschädigung der elektronischen Bauteile 30 während der Montage deutlich minimiert.The one end 22 of the one handle hook 20, which also has the connection points 24, is bent. As a result, the connection points 24 form an approximately horizontal plane. When mounting the outside door handle 10 so the first handle hook 20 can be mounted with the handle shell 12. Thereafter, the electronic components 30, which here comprise a printed circuit board, which is equipped with other components include, are introduced into the space 13 of the handle shell 12 and the contacting of the connection points 24 of a handle hook 20 with the mating connection points 32 of the electronic components 30 done in a simple manner. This contacting can also be brought about here for example by soldering or crimping. Alternatively, however, the terminals 24 and the mating terminals 32 may also be included This embodiment may be designed so that the contacting takes place automatically when positioning the electronic components 30 in the space 13 of the handle shell 12. Particularly advantageous in the embodiment shown here is that the electronic components 30 need not be pre-assembled with the one handle hook 20. Thus, the risk of damage to the electronic components 30 during assembly is significantly minimized.

Den hier dargestellten Ausführungsformen ist gemeinsam, dass der Kontaktbereich, also der Bereich der Anschlussstellen 24 und der Gegenanschlussstellen 32, innerhalb der Vergussmasse 40 liegt. Hierdurch werden nachträgliche Beschädigungen, Verschmutzungen, Korrosionen oder Ähnliches, die die Funktionsweise der elektronischen Bauteile 30 beeinträchtigen können, vermieden. Abschließend sei noch darauf hingewiesen, dass die hier dargestellten Ausführungsformen lediglich beispielhafte Verwirklichungen der Erfindung darstellen. Es sind vielmehr noch allerlei Abwandlungen im Rahmen der durch die Ansprüche definierten Erfindung möglich. Insbesondere kann die Griffschale auch aus mehreren Teilen bestehen, ebenso auch die Blende. Es ist auch möglich, beide Griffhaken als gesonderte Elemente mit der Griffschale zu verbinden. Der Stecker am Griffhaken kann vielerlei Ausgestaltungen haben und es können auch mehr als zwei Leitungen von den elektronischen Bauteilen zur Fahrzeugelektronik führen. Es ist auch möglich, bei einem Türgriff mit Taster zuerst die elektronischen Bauteile und dann den Taster zu montieren oder aus dem Taster und den Bauteilen vorher eine Baueinheit zu bilden.The embodiments shown here have in common that the contact region, that is to say the region of the connection points 24 and the counter-connection points 32, lies within the potting compound 40. As a result, subsequent damage, contamination, corrosion or the like, which may affect the operation of the electronic components 30, avoided. Finally, it should be pointed out that the embodiments illustrated here represent only exemplary implementations of the invention. Rather, all sorts of modifications are possible within the scope of the invention defined by the claims. In particular, the grip can also consist of several parts, as well as the aperture. It is also possible to connect both handle hooks as separate elements with the handle shell. The plug on the handle hook can have many forms and it can also lead more than two lines from the electronic components to the vehicle electronics. It is also possible for a door handle with a button first to mount the electronic components and then the button or previously form a unit from the button and the components.
