Description
Die vorliegende Erfindung betrifft ein Griffteil für eine Kraftfahrzeugtür umfassend einen Basiskörper mit wenigstens einem Hohlraum, in den mindestens ein elektrischer Leiter mündet, und zumindest eine Elektronikeinheit, die in dem wenigstens einen Hohlraum anordenbar und mit dem mindestens einen elektrischen Leiter verbindbar ist.The present invention relates to a handle part for a motor vehicle door comprising a base body having at least one cavity into which opens at least one electrical conductor, and at least one electronic unit which can be arranged in the at least one cavity and connectable to the at least one electrical conductor.
Solche Griffteile sind insbesondere geeignet, Prozessoren, Sensoren, Antriebe, Antennen und ähnliche elektrische Bauteile in sich aufzunehmen und damit beispielsweise auch die Möglichkeit zu schaffen, Tastsensoren außerhalb des Kraftfahrzeugs zu positionieren. Darüber hinaus können auch berührungslose Sensoren zur Verwirklichung des so genannten "keyless entry" zum Einsatz gelangen.Such gripping parts are particularly suitable for accommodating processors, sensors, drives, antennas and similar electrical components and thus for example also providing the possibility to position touch sensors outside the motor vehicle. In addition, non-contact sensors for realizing the so-called "keyless entry" can be used.
Aus der
Bei solchen Türgriffen kann sich die Montage jedoch teilweise schwierig gestalten. Dies ist insbesondere damit zu begründen, dass die elektrische Kontaktierung der Leiterplatte mit dem Flachbandkabel auf kleinem, nicht einsehbarem Raum stattfinden muss. Darüber hinaus ist auch festzustellen, dass bei einem einmaligen Vergießen einer solchen Türgriffeinheit die Reparatur bzw. die Erweiterung der Funktionen des Türgriffs nur schwer möglich ist. Dies führt jedoch zu einer relativ großen Variantenvielfalt der Türgriffe für Kraftfahrzeuge und erhöht gegebenenfalls auch die Wartungskosten.In such door handles, however, the assembly can sometimes be difficult. This is due in particular to the fact that the electrical contacting of the printed circuit board with the ribbon cable must take place in a small, non-visible space. In addition, it should also be noted that in a single casting of such a door handle unit, the repair or extension of the functions of the door handle is difficult. However, this leads to a relatively large variety of variants of the door handles for motor vehicles and possibly also increases the maintenance costs.
Hiervon ausgehend ist es Aufgabe der vorliegenden Erfindung, die mit Bezug auf den Stand der Technik geschilderten technischen Probleme zumindest teilweise zu lösen. Insbesondere soll ein Türgriff angegeben werden, der auch unter Gesichtspunkten einer automatisierten Fertigung in der Großserie flexibel hergestellt und eingesetzt werden kann. Dabei soll insbesondere die Wartungsfreundlichkeit und/oder der Montagekomfort verbessert werden. Schließlich ist auch eine sichere und dauerhafte Konektierung der innenliegenden Elektronikeinheit gerade bei extremen Fahrbedingungen des Kraftfahrzeuges zu gewährleisten.On this basis, it is an object of the present invention to at least partially solve the technical problems described with reference to the prior art. In particular, a door handle is to be specified, which can also be flexibly manufactured and used in terms of automated production in mass production. In particular, the ease of maintenance and / or the ease of assembly should be improved. Finally, a secure and permanent Konektierung the internal electronics unit is to ensure just under extreme driving conditions of the motor vehicle.
Diese Aufgaben werden gelöst mit einem Griffteil gemäß den Merkmalen des Patentanspruchs 1. Weitere vorteilhafte Ausgestaltungen der Erfindung sind in den abhängig formulierten Patentansprüchen angegeben. Es ist darauf hinzuweisen, dass die in den Patentansprüchen einzeln aufgeführten Merkmale in beliebiger, technologisch sinnvoller, Weise miteinander kombiniert werden können und weitere Ausgestaltungen der Erfindung aufzeigen. Zudem veranschaulicht die Beschreibung jedes Merkmal im Detail, so dass weitere besonders bevorzugte und vorteilhafte Ausgestaltungen dort erläutert werden.These objects are achieved with a handle according to the features of claim 1. Further advantageous embodiments of the invention are specified in the dependent formulated claims. It should be noted that the features listed individually in the claims in any technologically meaningful way, can be combined with each other and show other embodiments of the invention. In addition, the description illustrates each feature in detail, so that further particularly preferred and advantageous embodiments are explained there.
Das erfindungsgemäße Griffteil für eine Kraftfahrzeugtür umfasst einen Basiskörper mit wenigstens einem Hohlraum, in den mindestens ein elektrischer Leiter mündet, und zumindest eine Elektronikeinheit, die in dem wenigstens einen Hohlraum anordenbar und mit dem mindestens einen elektrischen Leiter verbindbar ist, wobei zusammenwirkende Mittel zum Positionieren der Elektronikeinheit bezüglich des mindestens einen Leiters im Hohlraum und an der Elektronikeinheit vorgesehen sind.The motor vehicle door handle according to the invention comprises a base body having at least one cavity into which at least one electrical conductor terminates, and at least one electronics unit connectable in the at least one cavity and connectable to the at least one electrical conductor, wherein cooperating means for positioning the Electronic unit are provided with respect to the at least one conductor in the cavity and on the electronic unit.
Grundsätzlich ist anzumerken, dass ein solches Griffteil aus einer Vielzahl unterschiedlicher Teile hergestellt sein kann, wobei der wenigstens eine Hohlraum zumindest von einem so genannten Basiskörper umgeben bzw. teilweise von diesem begrenzt ist. Regelmäßig wird ein solcher Basiskörper nur einen Hohlraum auf weisen, dies ist jedoch nicht zwingend erforderlich. Auch die Anzahl der elektrischen Leiter, die in diesen Hohlraum münden, muss nicht auf einen elektrischen Leiter begrenzt sein, vielmehr können zur Steuerung bzw. zum Betrieb der wenigstens einen Elektronikeinheit auch mehrere elektrische Leiter vorgesehen sein. Im Normalfall wird ein solches Griffteil nur mit einer einzelnen Elektronikeinheit ausgeführt sein, gleichwohl kann es beispielsweise aufgrund der Form des Basiskörpers bzw. des Griffteils u. U. erforderlich sein, die Elektronikeinheit in zwei Module zu unterteilen und getrennt voneinander in einem gemeinsamen oder jeweils in einem Hohlraum anzuordnen.In principle, it should be noted that such a grip part can be produced from a multiplicity of different parts, wherein the at least one cavity is surrounded or at least delimited by a so-called base body. Regularly, such a base body only have a cavity, but this is not absolutely necessary. Also, the number of electrical conductors that open into this cavity need not be limited to an electrical conductor, but may be provided for controlling or operating the at least one electronic unit and a plurality of electrical conductors. Normally, such a grip part will be executed only with a single electronic unit, however, it may, for example due to the shape of the base body or the handle part u. U. be required to divide the electronics unit into two modules and to arrange separately from each other in a common or each in a cavity.
Hier wird nun erfindungsgemäß vorgeschlagen, dass Mittel zum Positionieren der Elektronikeinheit bezüglich des mindestens einen Leiters vorgesehen sind, wobei diese Mittel sowohl mit dem Hohlraum als auch mit der Elektronikeinheit gebildet sind und diese Mittel demnach zum Positionieren zusammenwirken. Insbesondere korrespondieren die Mittel im Hohlraum und an der Elektronikeinheit miteinander. Dabei sind insbesondere auf den Oberflächen im Bereich des Hohlraums bzw. im Bereich der Elektronikeinheit äußere Geometrien geschaffen, die miteinander zur Anlage gebracht werden können, so dass sich beispielsweise eine Art formschlüssige Verbindung zwischen dem Hohlraum und der Elektronikeinheit ausbildet.Here, according to the invention, it is proposed that means be provided for positioning the electronic unit with respect to the at least one conductor, wherein these means are formed both with the cavity and with the electronic unit and these means therefore cooperate for positioning. In particular, the means in the cavity and on the electronic unit correspond to each other. In particular, on the surfaces in the region of the cavity or created in the electronic unit outer geometries that can be brought to bear against each other, so that, for example, forms a kind of positive connection between the cavity and the electronic unit.
In diesem Zusammenhang wird als bevorzugte Variante angegeben, dass die zusammenwirkenden Mittel zum Positionieren eine im Hohlraum ausgebildete Steckverbindung umfassen. Folglich wird mit dem Hohlraum insbesondere eine Negativform eines Steckers ausgeformt, während ein Teil der Elektronikeinheit eine positive Form eines Steckers ausbildet. Diese beiden korrespondierenden Teile können nun in Umfangsrichtung aneinander zur Anlage gebracht werden, so dass die Steckerverbindung ausgebildet ist. Insoweit ist eine vorteilhafte Funktionsvereinigung von Positionierung und Bereitstellung eines elektrischen Kontaktes angegeben.In this connection, as a preferred variant, it is stated that the cooperating positioning means comprise a plug-in connection formed in the cavity. Consequently, in particular a negative form of a plug is formed with the cavity, while a part of the electronic unit forms a positive shape of a plug. These two corresponding parts can now be brought into abutment in the circumferential direction, so that the plug connection is formed. In that regard, an advantageous combination of functions of positioning and providing an electrical contact is specified.
Darüber hinaus wird auch vorgeschlagen, dass die zusammenwirkenden Mittel zum Positionieren eine freitragende Halterung für die Elektronikeinheit umfassen. Damit ist insbesondere gemeint, dass zumindest während der Montage bzw. während eines nachfolgenden Bearbeitungsschrittes eine Fixierung bzw. Ausrichtung der Elektronikeinheit in dem Hohlraum allein über diese zusammenwirkenden Mittel nach Art einer freitragenden Halterung bewerkstelligt wird. Folglich stellen diese Haltemittel, insbesondere die entsprechenden Steckverbindungen, sicher, dass andere Bestandteile der Elektronikeinheit sich frei in den Hohlraum ohne weiteren Kontakt mit dem Basiskörper erstrecken.In addition, it is also proposed that the cooperating means for positioning comprise a cantilevered mounting for the electronics unit. This means in particular that at least during assembly or during a subsequent processing step, a fixation or alignment of the electronics unit in the cavity is accomplished alone on these cooperating means in the manner of a cantilevered bracket. Consequently, these holding means, in particular the corresponding plug connections, ensure that other components of the electronic unit extend freely into the cavity without further contact with the base body.
Darüber hinaus wird auch ein Griffteil als vorteilhaft erachtet, bei dem die zusammenwirkenden Mittel zum Positionieren einen wiederholbar lösbaren Kontakt zwischen dem mindestens einen elektrischen Leiter und der Elektronikeinheit bilden. Damit kann insbesondere die Nachrüstbarkeit des Griffteils mit erweiterten Sensoren, erneuerten elektronischen Bauteilen und dergleichen realisiert werden, ohne die Gefahr einer Beschädigung des elektrischen Leiters im Inneren des Basiskörpers.In addition, a gripping member is also considered advantageous, in which the cooperating means for positioning form a repeatable detachable contact between the at least one electrical conductor and the electronics unit. This can in particular the retrofittability of the handle with extended Sensors, renewed electronic components and the like can be realized without the risk of damage to the electrical conductor inside the base body.
Ganz besonders bevorzugt sind die zusammenwirkenden Mittel zum Positionieren so gestaltet, dass diese eine Steckverbindung als freitragende Halterung umfassen, die einen elektrischen Kontakt hin zum Leiter wiederholbar lösbar gestalten.Most preferably, the cooperating means for positioning are designed to include a plug-in connection as a cantilevered bracket that removably removes electrical contact to the conductor.
Gemäß einer Weiterbildung des Griffteils wird auch vorgeschlagen, dass die zusammenwirkenden Mittel zum Positionieren auch Mittel zum Abdichten des elektrischen Leiters gegenüber dem Hohlraum umfassen. Damit ist insbesondere gemeint, dass beispielsweise im Bereich der Steckverbindung bzw. im Bereich der Halterung Dichtmittel vorgesehen sind, die gegebenenfalls den Hohlraum sogar unterteilen, nämlich in einen Kontaktbereich und einen Aufnahmebereich für die Elektronikeinheit. Der Kontaktbereich betrifft den Teil des Hohlraums, aus dem die elektrischen Leiter hervorstehen bzw. mit einer entsprechenden Steckerverbindung verbunden sind. Die Dichtung hat insbesondere die Aufgabe, diesen Kontaktbereich vor Feuchtigkeit oder aber auch vor der Kunststoffmasse zu schützen, die gegebenenfalls nachträglich beim Umspritzen der Elektronikeinheit zugeführt wird.According to a development of the grip part, it is also proposed that the cooperating means for positioning also comprise means for sealing the electrical conductor with respect to the cavity. This means in particular that, for example, in the region of the plug-in connection or in the region of the holder, sealing means are provided which optionally even subdivide the cavity, namely into a contact region and a receiving region for the electronic unit. The contact area refers to the part of the cavity from which the electrical conductors protrude or are connected to a corresponding plug connection. The seal has the particular task of protecting this contact area from moisture or even from the plastic compound, which is optionally supplied later in the encapsulation of the electronics unit.
Schließlich kann die Elektronikeinheit wenigstens einen Sockel zur Kontaktierung des Griffteils und wenigstens einen Komponententräger für zumindest ein elektronisches Bauteil aufweisen. Der Sockel ist insbesondere nach Art eines positiven Steckerteils ausgeformt, weist also insbesondere Aufnahmen für einen elektrischen Leiter auf. Der Komponententräger ist der Einfachheit halber als starres plattenähnliches Bauteil gestaltet, auf dem die elektronischen Bauteile befestigt und gegebenenfalls miteinander elektrisch leitend verbunden sind. Elektronische Bauteile können insbesondere Kondensatoren, Widerstände, Sensoren, Antennen, Taster und dergleichen sein. Ganz besonders bevorzugt ist der Sockel relativ groß ausgeführt, so dass eine möglichst große Kontaktfläche mit dem Basiskörper gewährleistet ist. So hat der Sockel beispielsweise eine Querschnittsfläche, die mindestens ein Drittel der Querschnittsfläche des Komponententrägers ausmacht, insbesondere sogar zumindest halb so groß ist wie der Komponententräger.Finally, the electronic unit may have at least one base for contacting the grip part and at least one component carrier for at least one electronic component. The base is shaped in particular in the manner of a positive plug part, so in particular has receptacles for an electrical conductor. For the sake of simplicity, the component carrier is designed as a rigid plate-like component on which the electronic components are fastened and optionally electrically conductively connected to one another. Electronic components may in particular be capacitors, resistors, sensors, antennas, Be button and the like. Most preferably, the base is made relatively large, so that the largest possible contact surface is ensured with the base body. For example, the base has a cross-sectional area which makes up at least one third of the cross-sectional area of the component carrier, in particular even at least half as large as the component carrier.
Darüber hinaus wird als vorteilhaft erachtet, dass in dem wenigstens einen Hohlraum eine Elektronikeinheit positioniert ist, wobei eine Kunststoffmasse den Hohlraum im Übrigen ausfüllt. Das betrifft insbesondere den Bereich des Hohlraums, der sich von den Dichtmitteln bis hin zur Öffnung des Hohlraums gegenüber der Umgebung erstreckt. Durch das Umspritzen der Elektronikeinheit wird sichergestellt, dass sich diese Position während des Betriebes des Kraftfahrzeuges nicht wesentlich ändert, so dass insbesondere auch die Steckverbindung nicht einer allzu hohen Schwingungsbelastung ausgesetzt ist.In addition, it is considered advantageous that in the at least one cavity an electronic unit is positioned, wherein a plastic mass fills the cavity otherwise. This particularly relates to the region of the cavity, which extends from the sealing means to the opening of the cavity relative to the environment. By encapsulating the electronics unit ensures that this position does not change significantly during operation of the motor vehicle, so that in particular the connector is not exposed to an excessive vibration load.
Schließlich wird auch vorgeschlagen, dass der wenigstens eine Hohlraum mittels einer Klappe verschließbar ist. Die Klappe kann einstückig mit dem Basiskörper verbunden sein, es kann sich hierbei aber auch um ein separat applizierbares Bauteil handeln. Die Klappe dient beispielsweise zum Schutz der Elektronikeinheit und/oder der umspritzten Kunststoffmasse. Diese Klappe kann mit einer Klipsverbindung und/oder aber mit zusätzlichen Verbindungsmitteln sicher an dem Basiskörper befestigt werden.Finally, it is also proposed that the at least one cavity can be closed by means of a flap. The flap may be integrally connected to the base body, but this may also be a separately applicable component. The flap is used, for example, to protect the electronics unit and / or the overmolded plastic compound. This flap can be securely fastened to the base body with a clip connection and / or with additional connecting means.

In einem Endbereich des Basiskörpers 3 ist ein Hohlraum 4 gebildet, wie aus dem Teilschnitt erkennbar ist. In diesen Hohlraum 4 mündet ein elektrischer Leiter 5, der den Hohlraum 4 mit dem Anschluss 15 hin zu einer Kraftfahrzeugtür verbindet. Alternativ ist der Anschluss 15 (bzw.

Um nunmehr eine einfache Montage dieser Elektronikeinheit 6 zu gewährleisten, ist der relativ groß ausgeführte Sockel 9 nach Art eines positiven Steckers ausgebildet, wobei außen in Umfangsrichtung des Sockels 9 eine Dichtungslippe bzw. mehrere Dichtungslippen 14 vorgesehen sind, die in Kontakt mit der Begrenzungsfläche des Hohlraums 4 gebracht werden können. Damit kann eine Unterteilung des Hohlraums 4 in einen Kontaktbereich und einen Lagebereich für die Elektronikeinheit bewirkt werden. Senkrecht zu diesen Dichtungslippen 14 ist darüber hinaus wenigstens eine Führungshilfe 17 (z.B. nach Art einer Nut) gebildet, die beispielsweise mit entsprechend geformten Wandbereichen des Hohlraumes 4 bzw. des Basiskörpers 3 beim Einschieben der Elektronikeinheit 6 in den Hohlraum 4 zusammenwirkt.
