Abstract

The invention relates to an external handle on doors or hatches of vehicles, using a two piece (10, 20) housing, wherein a cavity (21) is generated between said pieces. A sensor (31, 32) is arranged in said cavity in a container (30). On operation, the sensor carries out certain functions in the lock. According to the invention, failures caused by the ingress of fluids into the cavity (21) can be avoided, wherein the container (30) is formed from an elastic molded mass (35), in which the sensor (31, 32) and optionally some further electric and/or electronic components for the sensor operation are embedded. An elastic surface (36) is achieved on at least one end piece of the container (30) by means of the molded mass (35). When assembled, the container (30) is pressed (41) with said elastic surface (36) against an inner surface (29) of the housing piece (10, 20). On pressing (41), the end piece of the container (30) deforms and functions as sealing means (40'), preventing an ingress of fluid between the container surface (36) and the housing inner surface (29).

Description

Außengriff an Türen oder Klappen von Fahrzeugen External handle on doors or flaps of vehicles
Die Erfindung richtet sich auf einen Türaußengriff der im Oberbegriff des Anspruches 1 angegebenen Art, wo der Türaußengriff ein zweiteiliges Gehäuse aufweist. Dieses Gehäuse besteht aus einem Griffkörper, der im Montagefall sowohl zur Anbringung des Türaußengriffs an der Tür als auch zum Öffnen eines an der Tür vorgesehenen Schlosses dient. Der andere Teil des Gehäuses ist ein Griffdeckel. Zwischen dem Griffdeckel und dem Griffkörper entsteht ein Hohlraum, der zur Aufnahme eines Containers dient.The invention is directed to an outside door handle specified in the preamble of claim 1, where the outside door handle has a two-part housing. This housing consists of a handle body, which serves in the case of installation both for attaching the outside door handle to the door and for opening a lock provided on the door. The other part of the housing is a handle cover. Between the handle cover and the handle body creates a cavity which serves to receive a container.
Die DE 199 35 290 Al zeigt einen solchen Türaußengriff. Wenn der Elektronikcontainer als elektrischer Sensor ausgebildet ist, entstehen Probleme durch ins Innere des Hohlraums eintretende Flüssigkeiten. Die Spalte zwischen den Oberflächen des Containers und Innenflächen des Gehäuses ziehen durch Kapillarwirkung die Flüssigkeiten an. Dann ist der Sensor unbrauchbar.DE 199 35 290 A1 shows such an outside door handle. If the electronics container is designed as an electrical sensor, problems arise due to liquids entering the interior of the cavity. The gaps between the surfaces of the container and inner surfaces of the housing attract the liquids by capillary action. Then the sensor is unusable.
Der Erfindung liegt die Aufgabe zugrunde, einen Türaußengriff der im Oberbegriff des Anspruches 1 genannten Art zu entwickeln, der dieses Problem beseitigt. Dies wird durch die in Anspruch 1 angegebenen Maßnahmen erreicht, denen folgende besondere Bedeutung zukommt.The invention has for its object to develop a door outside handle mentioned in the preamble of claim 1, which eliminates this problem. This is achieved by the measures specified in claim 1, which have the following special significance.
Für die Ausbildung des Containers wird eine elastische Vergussmasse verwendet, in welcher der Sensor und/oder wenigstens einige der zum Sensor-Betrieb dienenden elektrischen und/oder elektronischen Bauteile eingebettet sind. Diese Vergussmasse erzeugt eine elastische Oberfläche an wenigstens einem Endstück des Containers, die im Montagefall gegen die Innenfläche des Gehäusedeckels oder des Gehäusekörpers gepresst wird. Bei dieser Anpressung wird das Endstück des Containers verformt und ist ein Dichtungsmittel, welches ein Eindringen von Flüssigkeit zwischen die Container-Oberfläche und die Gehäuse-Innenfläche verhindert. Daher ist die Funktionsfähigkeit der Sensoren durch in diesen eintretende Flüssigkeiten nicht mehr beeinträchtigt.For the formation of the container, an elastic potting compound is used, in which the sensor and / or at least some of the sensor operation serving electrical and / or electronic components are embedded. This potting compound creates an elastic surface on at least one end of the container, the is pressed in the case of installation against the inner surface of the housing cover or the housing body. In this contact pressure, the end piece of the container is deformed and is a sealing means, which prevents ingress of liquid between the container surface and the housing inner surface. Therefore, the functionality of the sensors is no longer impaired by the fluids entering them.
Die erfindungsgemäße Gestaltung ist insbesondere bei kapazitiv wirksamen Sensoren bedeutsam, die ein elektrisches Feld erzeugen. Die Vergussmasse des Containers dient nämlich als Dielektrikum für das elektrische Feld. Wenn eindringende Flüssigkeiten erfindungsgemäß daran gehindert werden, in diesen Bereich einzutreten, so können diese auch nicht die physikalischen Eigenschaften des Dielektrikums verfälschen.The design according to the invention is particularly significant in the case of capacitive sensors which generate an electric field. The potting compound of the container serves as a dielectric for the electric field. If penetrating liquids are prevented from entering this area according to the invention, they can not falsify the physical properties of the dielectric.

Wie Fig. 1 zeigt, ist der Türaußengriff als ein zweiteiliges Gehäuse ausgebildet, nämlich mit einem als Basis dienenden Griffkörper 10 und einem diesen überdeckenden Griffdeckel 20. Der Griffkörper 10 besitzt zwei Enden 11 , 12 mit unterschiedlicher Funktion. Das eine Körperende 11 ist endseitig mit einer Drehlagerstelle 13 versehen, die bei eingebautem Türaußengriff an einer Gegenlagerstelle eines nicht näher gezeigten Trägers angreift und dadurch den ganzen Türaußengriff schwenkbeweglich macht. Der Träger ist an der Tür oder Klappe eines Fahrzeugs befestigt. Dieses Körperende 11 ist folglich ein Lagerende und dient zur Lagerung des Türaußengriffs an der Tür des Fahrzeugs.As shown in FIG. 1, the outside door handle is designed as a two-part housing, namely with a serving as a base handle body 10 and this covering the handle cover 20. The handle body 10 has two ends 11, 12 with different function. The one end of the body 11 is provided at the end with a pivot bearing 13, which with built-in outside door handle on a Counter bearing of a carrier not shown in detail attacks and thereby makes the whole outer door handle pivotal. The carrier is attached to the door or flap of a vehicle. This body end 11 is thus a bearing end and serves for the storage of the outside door handle on the door of the vehicle.
Das andere Körperende 12 ist als Ausleger ausgebildet und mit einem endseitigen Haken 14 versehen, der ein Anfangsglied eines nicht näher gezeigten Schlosses in der Tür oder Klappe des Fahrzeugs hintergreift. Bei Betätigung des Türaußengriffs wird über den Haken 14 das Anfangsglied erfasst und das Schloss betätigt. Dieses zweite Körperende 12 ist also das Betätigungsende des Türaußengriffs. Ein Mittelabschnitt 17 des Griffkörpers 10 ist als eine Schale 15 ausgebildet, die nach außen, nämlich im Sinne des Pfeiles 16, offen ist.The other body end 12 is formed as a boom and provided with an end hook 14 which engages behind an initial member of a lock not shown in the door or flap of the vehicle. When the outside door handle is actuated, the starting element is detected via the hook 14 and the lock is actuated. This second body end 12 is thus the operating end of the outside door handle. A central portion 17 of the handle body 10 is formed as a shell 15 which is open to the outside, namely in the direction of arrow 16, open.
Der Griffdeckel 20 ist vor allem im Mittelabschnitt 17 des Griffkörpers 10 zugeordnet und als eine Gegenschale 25 ausgebildet, die ihre Öffnung in Richtung des nach innen weisenden Pfeils 26 aufweist. Fig. 2b zeigt den Montagefall zwischen dem Griffkörper 10 und dem Griffdeckel 20. Dann greifen die Schale 15 und die Gegenschale 25 mit ihren Seitenwänden 18, 28 ineinander. Zwischen der Schale 15 und der Gegenschale 25 entsteht ein Hohlraum 21. Die ineinandergreifenden Seitenwände 18, 28 sind miteinander verbunden. Die Verbindung kann z.B. durch Rastverschlüsse 22 geschehen, die im vorliegenden Fall aus einem Rastvorsprung 23 an der Außenseite der Schalen-Seitenwand 18 und als Rastvertiefung 24 an der Innenseite der Gegenschalen-Seitenwand 28 bestehen. Zur Sicherung der Eingriffslage könnten alternativ oder ergänzend Schraubmittel eingesetzt werden.The handle cover 20 is associated in particular in the central portion 17 of the handle body 10 and formed as a counter-shell 25 having its opening in the direction of the inward-pointing arrow 26. Fig. 2b shows the mounting case between the handle body 10 and the handle cover 20. Then grab the shell 15 and the counter shell 25 with their side walls 18, 28 into one another. Between the shell 15 and the counter shell 25, a cavity 21 is formed. The intermeshing side walls 18, 28 are interconnected. The compound can e.g. performed by snap fasteners 22, which consist in the present case of a locking projection 23 on the outside of the shell side wall 18 and as a detent recess 24 on the inside of the counter-shell side wall 28. To secure the engagement position, alternatively or additionally, screwing means could be used.
Der Hohlraum 21 nimmt im Montagefall einen besonderen Container 30 auf, der über verschiedene elektrische Signal- und Betriebsleitungen 33 mit entsprechenden Steuergeräten und/oder mit einer Stromquelle elektrisch verbunden ist. Zur elektrischen Verbindung kann ein elektrischer Stecker 34 am Ende der Leitungen 33 dienen. Wenn der Griffdeckel 20 mit dem Griffkörper 10 verbunden ist, ragen die elektrischen Leitungen 31 zusammen mit dem Stecker 34 am Lagerende 11 des Türaußengriffs heraus, wo sie mit entsprechenden nicht näher gezeigten Gegensteckern gekuppelt werden können. Wie aus dem Querschnitt von Fig. 2a zu erkennen ist, beinhaltet der Container 30 zwei Elektroden 31 , 32, die zu zwei wirkunterschiedlichen kapazitiven Sensoren gehören. Der eine Sensor 31 dient zur Verriegelung des Schlosses, während der andere Sensor 32 für die Entriegelung des Schlosses sorgt. Die beiden Sensoren 31 , 32 sprechen an, wenn zwecks Betätigung des Türaußengriffs die Hand einer berechtigten Person sich der ersten bzw. der zweiten Elektrode 31, 32 der beiden Sensoren nähert.The cavity 21 receives in the case of installation on a special container 30 which is electrically connected via various electrical signal and operating lines 33 with corresponding control devices and / or with a power source. For electrical connection, an electrical connector 34 at the end of the lines 33 serve. When the handle cover 20 is connected to the handle body 10, projecting the electrical leads 31 together with the plug 34 at the bearing end 11 of the outside door handle, where they can be coupled with corresponding mating connectors not shown in detail. As can be seen from the cross-section of Fig. 2a, the container 30 includes two electrodes 31, 32 belonging to two different capacitive sensors. The one sensor 31 serves to lock the lock, while the other sensor 32 provides for the unlocking of the lock. The two sensors 31, 32 respond when, for the purpose of actuating the outside door handle, the hand of an authorized person approaches the first or the second electrode 31, 32 of the two sensors.
Die beiden Elektroden 31 , 32 sind in einer durch Punktschraffur hervorgehobenen Vergussmasse 35 eingebettet, die elastisch nachgiebig ausgebildet ist. In dieser Vergussmasse 35 können auch weitere zum Betrieb der beiden Sensoren 31 , 32 dienende elektronische und elektrische Bauteile integriert sein. Durch die Vergussmasse 35 entstehen am Container 30 die im Sinne der beiden auch in Fig. 2a eingezeichneten Pfeile 16, 26 nach außen bzw. innen weisende Oberflächen 36, 37. Von besonderer Bedeutung ist das aus dem elastischen Kunststoff bestehende Endstück 40 des Containers 30, welches die Container-Oberfläche 36 umschließt. Letzteres hat im Montagefall eine besondere, aus Fig. 2b ersichtliche Wirkung.The two electrodes 31, 32 are embedded in a potting compound 35, which is emphasized by dot-hatching and which has an elastically yielding design. In this potting compound 35 can also be integrated to operate the two sensors 31, 32 serving electronic and electrical components. By the potting compound 35 formed on the container 30 in the sense of the two drawn in Fig. 2a arrows 16, 26 outwardly or inwardly facing surfaces 36, 37. Of particular importance is made of the elastic plastic end piece 40 of the container 30, which encloses the container surface 36. The latter has a special, in Fig. Installation case apparent from Fig. 2b effect.
Fig. 2b zeigt den Montagefall der beiden Gehäuse-Schalen 10, 20, die einen durch Kraftpfeile 41 veranschaulichten Druck auf den im Hohlraum 21 befindlichen Container 30 ausüben. Das elastische Container-Endstück 40 von Fig. 2a wird entsprechend den Druckkräften 41 im Sinne der aus Fig. 2b ersichtlichen Form 40' deformiert. Die Folge ist, dass die Container-Oberfläche 36 gegen die Innenfläche 29 des Gehäusedeckels 20 gepresst wird. Das Container-Endstück 40 ist aufgrund seiner Deformation 40' ein Dichtungsmittel. Dieses Dichtungsmittel 40' verhindert ein Eindringen von etwaiger Flüssigkeit im Hohlraum 21 zwischen die Container- Oberfläche 36 und die Gehäuse-Innenfläche 29. Es entsteht dort eine aus Fig. 2b ersichtliche Anpresszone 47, die eine Kapillarwirkung der Flüssigkeit in diesem Bereich grundsätzlich ausschließt.FIG. 2 b shows the installation case of the two housing shells 10, 20, which exert a pressure, illustrated by force arrows 41, on the container 30 located in the cavity 21. The elastic container end piece 40 of FIG. 2a is deformed in accordance with the pressure forces 41 in the sense of the form 40 'shown in FIG. 2b. The result is that the container surface 36 is pressed against the inner surface 29 of the housing cover 20. The container end piece 40 is due to its deformation 40 'a sealant. This sealing means 40 'prevents penetration of any liquid in the cavity 21 between the container surface 36 and the housing inner surface 29. There arises an apparent from Fig. 2b Anpresszone 47, which excludes a capillary action of the liquid in this area basically.
Eine analoge Dichtungswirkung könnte bedarfsweise auch auf der gegenüberliegenden Container-Oberfläche 37 bezüglich der Griffkörper-Innenfläche 19 erfolgen. Derartige Anpresszonen 47 können also an mehreren Flächenseiten des Containers gleichzeitig erzeugt werden. Im vorliegenden Fall gibt es aber dort besondere Positioniermittel 44, die für eine definierte Lage des Containers 30 im Hohlraum 21 sorgen.An analogous sealing effect could, if necessary, also on the opposite container surface 37 with respect to the handle body inner surface 19 done. Such Anpresszonen 47 can therefore be generated simultaneously on several surface sides of the container. In the present case, however, there are special positioning means 44 which ensure a defined position of the container 30 in the cavity 21.
Die Positioniermittel 44 bestehen im dargestellten Ausführungsbeispiel aus einem Vorsprung 42 an der nach innen 26 weisenden Container-Oberfläche 37 einerseits und aus einer komplementären Vertiefung 43 an der nach außen weisenden Innenfläche 19 des Griffkörpers 10 andererseits. Die Eingriffslage der beiden Positioniermittel-Teile 42, 43 ist in Fig. 2b zu erkennen. Damit ist die seitliche Distanz 45, 46 des Containers 30 gegenüber den Innenflächen 38, 39 der inneren Seitenwand 28 gesichert. Das ist aus der Zusammenschau von Fig. 2a, 2b zu erkennen. Es versteht sich, dass anstelle einer Vertiefung 43 auch andere Positioniermittel, wie z.B. ein Gegenvorsprung am Griffkörper 10 vorgesehen sein könnte. Im Montagefall von Fig. 2b wird der Anpressdruck 41 über die Positioniermittel 44 auf den Container 30 ausgeübt, wodurch sein elastisches Endstück 40 von Fig. 2a ein Dichtungsmittel 40' von Fig. 2b wird.The positioning means 44 are in the illustrated embodiment of a projection 42 on the inwardly 26 facing container surface 37 on the one hand and from a complementary recess 43 on the outwardly facing inner surface 19 of the handle body 10 on the other. The engagement position of the two positioning means 42, 43 can be seen in Fig. 2b. Thus, the lateral distance 45, 46 of the container 30 against the inner surfaces 38, 39 of the inner side wall 28 is secured. This can be seen from the synopsis of Fig. 2a, 2b. It will be understood that instead of a recess 43 other positioning means, such as e.g. a counter-projection on the handle body 10 could be provided. In the case of installation of FIG. 2b, the contact pressure 41 is exerted on the container 30 via the positioning means 44, whereby its elastic end piece 40 of FIG. 2a becomes a sealing means 40 'of FIG. 2b.
Die Positioniermittel 44 sorgen im vorliegenden Fall für einen Abstand 48 zwischen dem Container 30 und der Innenfläche des Griffkörpers 10. Dieser Abstand 48 ist so groß ausgebildet, dass eine Kapillarwirkung von eintretenden Flüssigkeiten im Hohlraum 21 verhindert wird. Trotz der Flüssigkeiten wird für eine Funktionsfähigkeit des Sensors bzw. der Sensoren 31 , 32 gesorgt. Man könnte im vorliegenden Fall den Vorsprung 42 mit seinem aus der gegenüberliegenden Vertiefung 43 herausragenden Vorsprungsrest 49 als einen „Abstandhalter" für den Container 30 im Hohlraum 21 ansehen. Dieser Abstandhalter 49 ist, wie gesagt, mit der Container-Oberfläche 37 einstückig ausgebildet, weil dort die Vorsprünge 42 angeformt sind. So bildet der Container 30 und der Abstandhalter 49 eine vormontierte Baueinheit. Die Vorsprünge 42 bzw. Abstandhalter 49 sind einstückig mit dem Container 30 ausgebildet.The positioning means 44 provide in the present case for a distance 48 between the container 30 and the inner surface of the handle body 10. This distance 48 is formed so large that a capillary action of entering liquids in the cavity 21 is prevented. Despite the fluids, the functionality of the sensor or sensors 31, 32 is ensured. In the present case, it would be possible to view the projection 42 with its protruding remainder 49 projecting from the opposite recess 43 as a "spacer" for the container 30 in the cavity 21. This spacer 49 is, as stated, integrally formed with the container surface 37 because Thus, the container 30 and the spacer 49 form a preassembled structural unit The projections 42 or spacers 49 are integrally formed with the container 30.
Eine solche Einstückigkeit eines Abstandhalters könnte natürlich auch in analoger Weise mit den Innenflächen 19, 29 der beiden Griff-Bestandteile 10, 20 oder mit den Oberflächen des Griffdeckels 25 ausgebildet sein. Schließlich wäre es auch möglich, separate, vorgefertigte Einsätze als Abstandhalter zu verwenden, die in diesen Bereichen eingesetzt werden.Such a piece of a spacer could of course also in an analogous manner with the inner surfaces 19, 29 of the two handle components 10, 20 or with the Surfaces of the handle cover 25 may be formed. Finally, it would also be possible to use separate, prefabricated inserts as spacers which are used in these areas.
Im vorliegenden Fall sind die Sensoren 31, 32 kapazitiv wirksam und erzeugen ein elektrisches Feld, welches sich durch die abgedichtete Anpresszone 47 des Containers erstreckt. Die elastische Vergussmasse 35 des Containers 30 ist das Dielektrikum für das elektrische Feld. Die Kondensatorflächen des bzw. der beiden kapazitiven Sensoren 31 , 32 verlaufen im Montagefall im Wesentlichen parallel zu der abgedichteten Anpresszone 47 des Containers. Anstelle von kapazitiven Sensoren könnten natürlich auch andere Sensoren verwendet werden. In the present case, the sensors 31, 32 are capacitively effective and generate an electric field which extends through the sealed contact zone 47 of the container. The elastic potting compound 35 of the container 30 is the dielectric for the electric field. The capacitor surfaces of the two capacitive sensors 31, 32 extend in the case of installation substantially parallel to the sealed contact pressure zone 47 of the container. Of course, other sensors could be used instead of capacitive sensors.
