Abstract
Description
Die vorliegende Erfindung betrifft eine Vorrichtung zum Betätigen eines elektrischen Schließsystems und / oder eines in der Tür, einer Klappe oder dergl. eingebauten Schlosses für Fahrzeuge, mit einer beweglichen Handhabe zum Öffnen eines zugehörigen Tür- oder Klappenschlosses und einem angeordneten Sensor, womit ein Steuerbefehl aktiviert werden kann.The present invention relates to a device for actuating an electrical locking system and / or a lock installed in the door, a flap or the like can be.
Aus der DE 199 43 986 A1 ist eine Handhabe bekannt, die zur Betätigung eines elektrischen Schließsystems Sensoren, wie Druckschalter, enthält, um damit Schließ- oder Öffnungsbefehle an zugehörige Türschlösser durch Betätigung auszulösen. Dazu sind in der Handhabe in entsprechenden Ausnehmungen Druckschalter integriert. Bei Betätigung wird ein Stromkreis geschlossen und ein elektrisches Signal über aus der Handhabe herausgeführte elektrische Kabel zur Steuereinheit oder dem Schloß geleitet. Das elektrische Kabel wird über einen Stecker mit einer korrespondierenden Kupplung hinter der Öffnung des Türbleches verbunden, von wo aus die Leitung zum Schloß oder einer Steuerleitung geführt ist. Im Rahmen der Fahrzeugmontage sind die elektrischen Kabelstränge in der Karosserie bereits verlegt, wenn Türaußengriffe oder Griffklappen montiert werden. Insofern muß das Montagepersonal vor Befestigung des Türaussengriffs am Griffträger oder dem Türaußenblech, das elektrische Anschlußkabel durch die Blechöffnung führen und mit der Steckerkupplung verbinden.From DE 199 43 986 A1, a handle is known which contains sensors, such as pressure switches, for actuating an electrical locking system in order to thereby trigger closing or opening commands to associated door locks by actuation. For this purpose, pressure switches are integrated in the handle in corresponding recesses. When actuated, a circuit is closed and an electrical signal is routed to the control unit or the lock via electrical cables which are led out of the handle. The electrical cable is connected via a plug to a corresponding coupling behind the opening of the door panel, from where the line leads to the lock or a control line. As part of vehicle assembly, the electrical wiring harnesses are already installed in the body when external door handles or handle flaps are installed. In this respect, the assembly staff must lead the electrical connection cable through the sheet metal opening and connect it to the plug coupling before attaching the outer door handle to the handle bracket or the outer door panel.
Nachteilig ist bei dieser Anordnung, daß die Kabel aufwändig von Hand verlegt werden müssen, zum einen bei der Herstellung der Handhaben an sich und zum anderen bei der Montage der beweglichen Handhabe am Kraftfahrzeug.The disadvantage of this arrangement is that the cables have to be laboriously laid by hand, firstly in the manufacture of the handles themselves and secondly in the assembly of the movable handle on the motor vehicle.
Auch in der DE 100 62 042 A1 ist eine Vorrichtung zur Betätigung eines elektrischen Schließsystems mit einer Handhabe, die an einem Trägerteil zum Verschwenken gelagert ist, beschrieben. Die Handhabe weist elektronische Bauteile, wie Tastschalter, auf, zu deren Energieversorgung und zur Signalübertragung elektrische Kabel in der Nähe der Lagerstelle heraus geführt werden.
Am Ende weist das Kabel einen Stecker auf, der bei der Montage der Handhabe am Fahrzeug mit einer Gegenkupplung, die im Trägerteil gelagert ist, gekuppelt wird. Dabei ist das Kupplungselement schwenkbar am Trägerelement gelagert, um die Montage zu vereinfachen.DE 100 62 042 A1 also describes a device for actuating an electrical locking system with a handle, which is mounted on a carrier part for pivoting. The handle has electronic components, such as pushbuttons, for whose energy supply and for signal transmission, electrical cables are led out in the vicinity of the bearing point.
At the end, the cable has a plug which is coupled to a mating coupling which is mounted in the carrier part when the handle is mounted on the vehicle. The coupling element is pivotally mounted on the carrier element in order to simplify assembly.
Nachteilig ist dabei, daß das Trägerteil aufwändig konstruiert sein muß, um ein Wegklappen der Kupplung zu ermöglichen. Des Weiteren sind hohe Anforderungen an den Stecker und an die Kupplung in Bezug auf Schmutz- und Feuchtigkeitseinflüsse zu stellen, denn die Verbindung ist in der Tür, im sogenannten Feuchtraum, angeordnet. In diesem Bereich dringt Feuchtigkeit und Schmutz durch die Öffnungen im Türaußenblech, den Halteelementen und durch die darüberliegenden Dichtgummis der öffnungsfähigen Seitenscheiben. Der Konstruktionsaufwand bei Kupplungselementen und Steckern erhöhen zudem die Herstellkosten.
Da die Handhaben wie Zieh- oder Klappgriffe häufig bewegt werden, besteht zudem die Gefahr von Kabelbrüchen. In der Fahrzeugelektronik sind Kabelstecker immer kritische Elemente, in Bezug auf ihre Betriebssicherheit.The disadvantage here is that the carrier part must be constructed in a complex manner in order to enable the coupling to be folded away. Furthermore, there are high demands on the connector and the coupling with regard to dirt and moisture, because the connection is located in the door, in the so-called damp room. In this area, moisture and dirt penetrate through the openings in the outer door panel, the holding elements and through the overlying sealing rubbers of the opening side windows. The design effort for coupling elements and plugs also increases the manufacturing costs.
Since the handles such as pull handles or folding handles are moved frequently, there is also a risk of cable breaks. Cable connectors are always critical elements in vehicle electronics with regard to their operational safety.
Der vorliegenden Erfindung liegt somit die Aufgabe zugrunde Vorrichtungen zum Betätigen von elektrischen Schließsysteme zu realisieren, die eine einfache Konstruktion und Montage zur Kostenreduzierung ermöglichen. Zusätzlich sollen Ausfälle durch Kabelbrüche an Handhaben aufgrund bewegter Kabelelemente vermieden und die Betriebssicherheit entgegen den negativen Einflüssen von Feuchtigkeit und Schmutz erhöht werden.The present invention is therefore based on the object of realizing devices for actuating electrical locking systems which enable simple construction and assembly in order to reduce costs. In addition, failures due to cable breaks in handles due to moving cable elements are to be avoided and operational safety is to be increased against the negative effects of moisture and dirt.
Diese Aufgabe wird durch die im Patentanspruch 1 aufgeführten Merkmale gelöst.This object is achieved by the features listed in claim 1.
Die Vorrichtung zeichnet sich dadurch aus, daß in der Handhabe mindestens eine Sendeeinheit und die dazugehörige Empfangseinheit im Fahrzeug integriert ist und die Sendeeinheit die Sendeenergie aus einem piezoelektrischen Element, das in der Handhabe angeordnet ist, bezieht.The device is characterized in that at least one transmitter unit and the associated receiver unit are integrated in the vehicle in the handle and the transmitter unit obtains the transmit energy from a piezoelectric element which is arranged in the handle.
Durch die Betätigung des Piezo-Elementes an der Handhabe durch einen berechtigten Nutzer, wird elektrische Energie freigesetzt und dem Sendebaustein zugeführt, wodurch dieser Sender aktiviert wird und ein Signal an die Empfangseinheit sendet. Dabei wird der im Piezoelement erzeugte Strom als Sendeenergie und als Signal an sich verwendet. Die Energie zur Sendung des Signals bezieht der Sender einzig aus dem elektrischen Strom, der bei der Betätigung des Piezo-Elementes erzeugt wird. Die dabei erzeugte relativ geringe elektrische Ladung reicht dazu aus.
Dadurch sind keine Kabelverbindungen zur Signalübertragung und auch Energieversorgung der Sendeeinheit zwischen der beweglichen Handhabe und den anzusteuernden Schlössern oder der zentralen Fahrzeugsteuereinheit bzw. dem Fahrzeug notwendig. So fallen auch jedwede Kabelverbindungsteile, wie Steckerelemente, in die Feuchtigkeit und Schmutz eindringen kann, weg, wodurch die Materialkosten und Einbaukosten gemindert werden. Der Einbauaufwand in das Fahrzeug verringert sich enorm, da kein Kabel mehr von Hand durch Türöffnungen gezogen werden muß. Des weiteren wird ein Ausfall der Handhabe wegen beschädigtem Kabel oder defekten Steckerkupplungen vermieden.
Durch die Verwendung eines piezoelektrischen Elementes als Energieträger, werden keine anderweitigen Energiespeicher benötigt.By actuating the piezo element on the handle by an authorized user, electrical energy is released and fed to the transmitter module, whereby this transmitter is activated and sends a signal to the receiver unit. The current generated in the piezo element is used as transmission energy and as a signal per se. The transmitter obtains the energy for transmitting the signal solely from the electrical current that is generated when the piezo element is actuated. The relatively low electrical charge generated is sufficient for this.
As a result, no cable connections for signal transmission and also power supply of the transmission unit between the movable handle and the locks to be controlled or the central vehicle control unit or the vehicle are necessary. This also eliminates any cable connection parts, such as plug elements, into which moisture and dirt can penetrate, which reduces the material costs and installation costs. The installation effort in the vehicle is reduced enormously since no cable has to be pulled through door openings by hand. Furthermore, a failure of the handle due to damaged cables or defective plug couplings is avoided.
By using a piezoelectric element as an energy source, no other energy storage is required.
Vorzugsweise ist vorgesehen, daß die Empfangseinheit im Träger der zugehörigen Handhabe angeordnet ist.
Dadurch ist der Kommunikationsweg sehr kurz gehalten und es kann mit geringsten Sendeleistungen oder einfachen Sendemitteln gearbeitet werden. Der Energiebedarf des Senders wird dadurch minimal.
Durch diese Anordnung bildet der Träger zudem mit dem Empfänger eine ideale Baueinheit zum Einbau in ein Fahrzeug. Da die üblicherweise verwendeten Griffträger Kunststoffkonstruktionen sind, kann der Empfänger einfach integriert werden.It is preferably provided that the receiving unit is arranged in the carrier of the associated handle.
As a result, the communication path is kept very short and it is possible to work with the lowest transmission powers or simple transmission means. The transmitter's energy requirement is thereby minimal.
This arrangement also makes the carrier ideal with the receiver Unit for installation in a vehicle. Since the handle carriers commonly used are plastic constructions, the receiver can be easily integrated.
Vorzugsweise ist vorgesehen, daß die Kommunikation der Sende- und Empfangseinheit auf Funkbasis, vorzugsweise im GHz-Bereich in Bluetooth-Technik erfolgt.
Dadurch ist eine einfache Sender-Empfängerkommuniktion mit hoher Geschwindigkeit für den Nahbereich gegeben, so daß eine Betätigungsauftrag an ein Schloß in Millisek. erfolgen kann. Eine derartige Anordnung ermöglicht zudem die Ansteuerung mehrerer Empfänger im Fahrzeug, bei niedrigstem Energieverbrauch.It is preferably provided that the transmission and reception unit communicate on a radio basis, preferably in the GHz range using Bluetooth technology.
This gives a simple transmitter-receiver communication at high speed for the close range, so that an actuation order to a lock in milliseconds. can be done. Such an arrangement also enables the control of several receivers in the vehicle, with the lowest energy consumption.
Eine weitere vorteilhafte Ausbildung zeichnet sich dadurch aus, daß die Kommunikation der Sende- und Empfangseinheiten über Infrarot-Sende- und Empfangseinheiten realisiert wird.A further advantageous embodiment is characterized in that the communication between the transmitting and receiving units is realized via infrared transmitting and receiving units.
In einer weiteren vorteilhaften Ausbildung wird die Kommunikation der Sende- und Empfangseinheit auf Ultraschallbasis realisiert.In a further advantageous embodiment, the communication of the transmitting and receiving unit is realized on an ultrasound basis.
Vorzugsweise ist vorgesehen, daß mindestens ein Piezo-Element auf der zur Außenfläche der Tür oder Klappe zugewandten Seite der Handhabe angeordnet ist.It is preferably provided that at least one piezo element is arranged on the side of the handle facing the outer surface of the door or flap.
Vorzugsweise ist vorgesehen, daß mindestens ein Piezo-Element auf der zur Außenfläche der Tür oder Klappe abgewandten Seite der Handhabe angeordnet ist.It is preferably provided that at least one piezo element is arranged on the side of the handle facing away from the outer surface of the door or flap.
In einer vorteilhaften Ausgestaltung der Erfindung ist der Sensor ein piezoelektrisches Element, so daß der Sensor zum einen zur Signalerzeugung dient und gleichzeitig als Energieerzeuger für die Sendeeinheit dienen kann.In an advantageous embodiment of the invention, the sensor is a piezoelectric element, so that the sensor serves on the one hand for signal generation and at the same time can serve as an energy generator for the transmission unit.
Vorzugsweise ist vorgesehen, daß der Drucksensor als piezoelektrischer Lack auf der Handhabe aufgebracht ist. Dadurch kann das Piezoelement problemlos an jede Griffgeometrie angepaßt werden. Über die Flächengröße kann die Energiemenge eingestellt werden.It is preferably provided that the pressure sensor is applied to the handle as a piezoelectric lacquer. As a result, the piezo element can be easily adapted to any handle geometry. The amount of energy can be determined by the size of the area can be set.
Vorteilhafterweise ist diese Vorrichtung an einem Schwenkgriff oder einer Druckhandhabe integriert.This device is advantageously integrated on a swivel handle or a pressure handle.
Weitere Maßnahmen und Vorteile der Erfindung ergeben sich aus der nachfolgenden Beschreibung von Ausführungsbeispielen und den Zeichnungen.Further measures and advantages of the invention result from the following description of exemplary embodiments and the drawings.
In den Zeichnungen ist die Erfindung schematisch in zwei Ausführungsbeispielen ausgeführt:In the drawings, the invention is carried out schematically in two exemplary embodiments:

In Fig. 1 wird ein Fahrzeug (1) dargestellt, das mit einem elektrischen Schließsystem ausgerüstet ist. Dieses Schließsystem soll dem berechtigen Benutzer des Fahrzeugs (1) auf komfortable und einfache Weise den Zutritt zum Fahrzeug ( 1) ermöglichen. Bei diesem Ausführungsbeispiel sind an den zwei Türen (2) jeweils ein Türgriff ( 3) und ein elektrisches Schloß (4) angeordnet, wobei die Türgriffe (3) mittels eines Trägers (4) an der Tür (2) gefestigt ist. Der Träger (5) wird auf der Rückseite einer Tür (2) montiert, der in seiner Position mittels einer oder mehrere Schrauben an dem Türblech befestigt ist. Durch Ausnehmungen im Türblech (12) im Bereich des Trägers (5) wird die Handhabe (6) des Türgriffs (3), in diesem Fall ein Schwenkgriff in Form eines Ziehgriffes , mit dem Träger (5) verbunden.
Die Handhabe (6) weist Sensoren (7) auf, die durch Betätigung ein elektrisches Signal auslösen, die zu einer Steuereinheit (8) oder den elektrischen Schlössern (4) geleitet werden. Die Sensoren können Schaltelemente sein. Dort werden entsprechend Funktionen ausgelöst, wie z.B. Start der Identifizierungsabfrage zwischen einer Sende- und Empfangseinheit (9) und einem vom Benutzer mitgeführten ID-Geber, elektrisches Öffnen des Schlosses und damit der Tür (2), das automatische Schließen des gesamten Schließsystems (Zentralverriegelung) beim Verlassen des Fahrzeugs (1) oder Aktivieren der Double-Lock-Funktion, d.h. daß das Fahrzeug im abgeschlossenen Zustand auch nicht von innen geöffnet werden kann.
Ab dem Träger (5) des Türgriffes (3) werden die Signale über Kabel (10) an das Steuergerät (8) oder das Türschloß (4) übertragen. An der Heckklappe (11) ist auch ein Griff (3) mit entsprechendem Träger (5) und elektrischem Schloß (4) und Handhabe (6) vorgesehen.
In Figur 2 ist eine erfindungsgemäße Vorrichtung als Prinzipskizze dargestellt. Die Vorrichtung weist eine Handhabe (6) in Form eines Ziehgriffes auf. Dieser Ziehgriff ist in einem Griffträger (5) gelagert, der an der Innenseite eines Türaußenbleches (12) montiert ist. Der Griffträger (5) hat üblicherweise die Aufgabe die Lagerung der Handhabe und anderer Hebel- und Auslöseelemente, wie z.B. Crashsperre, Bowdenzugaufnahmen und Umlenkhebel aufzunehmen, die zum mechanischen Auslösen von Schlössern mittels Betätigung der Handhabe (6) dienen. Die Handhabe (6) ist an zwei Stellen im Griffträger (5) gelagert. Zum einen an der hinteren Lagerstelle (15), wo der Ziehgriff (3) um eine Achse, die nahezu senkrecht steht, schwenkbar ist, und zum anderen am vorderen Lager (18). Durch Ziehen der Handhabe (6) wird direkt oder indirekt über einen Zugelement (16) ein Schloß (4) in der Tür (2) des Fahrzeugs (1) betätigt. Das Zugelement (16) kann ein Bowdenzug sein.
In der Handhabe (6) sind zwei Drucksensoren (7, 17) auf piezoelektrischer Basis integriert, dabei sind diese Piezo-Elemente in Ausnehmungen (19,20) der Handhabe (6) eingesetzt.
Des weiteren befindet sich in der Handhabe (6) ein Sendemodul (13), das einen Modulator und eine Antenne umfaßt, um ein ausgelöstes Signal in ein sendefähiges Signal zu wandeln und zu senden. In diesem Fall wird das ausgelöste Signal per Funk in Bluetooth-Technik ausgesendet, wobei die Frequenz im Bereich von 1 bis 3 GHz liegt.
Im Griffträger (5) ist das Empfangsmodul (10) integriert.
Im Fall der Betätigung des Türgriffs (3) durch einen Benutzer wird durch die Hand des Benutzers Druck auf das Piezoelement (7,17) ausgeübt und ein Strom fließt, der das Sendemodul (13) aktiviert, so daß ein Funksignal gesendet wird. Das gesendete Signal wird von der Empfangseinheit (14) empfangen, in ein elektrisches Signal rückmoduliert und über eine Signalleitung/Kabel (10) zur zentralen Steuereinheit (8) oder direkt zum Schloß (4) gesendet, wonach eine Betätigung eines zugehörigen Schlosses (4) oder der angesprochenen Schlösser (4) erfolgt.
Das von der Sendeeinheit (13) gesendete Signal kann von mehreren Empfangseinheiten (14), die im Fahrzeug an verschiedenen Stellen integriert sein können, empfangen werden, um gleichzeitig an mehreren Stellen Betätigungen von Schlössern oder anderen Bauteilen zu realisieren. So kann das gesendete Signal von sämtlichen am Fahrzeug angeordneten Empfangseinheiten (14) zur Aktivierung einer Zentralverriegelungsfunktion empfangen werden oder aber auch nur von bestimmten Empfangseinheiten (14) im Fahrzeug (1), z.B. an Türinnengriffen zur Aktivierung deren Entkoppelung in der Double-Lock-Funktion.
Es ist auch denkbar, daß das von der Sendeeinheit ( 13) gesendete Signal von der zentralen Sende- und Empfangseinheit (9), die u.a. die Kommunikation mit dem ID-Geber herstellt, empfangen und von dort umgewandelt an die Steuereinheit (8) geleitet wird.
In Figur 3 ist eine alternative erfindungsgemäße Vorrichtung dargestellt, die sich von der vorher geschilderten Ausführung darin unterscheidet, daß die Handhabe (6) nur mit einem Sensor (7) ausgestattet ist, der z.B. bei Betätigung das Schließen der Zentralverriegelung veranlaßt. Dabei wirkt dieser als mechanischer Taster ausgeführte Sensor (7) auf ein piezoelektrisches Element, so daß darauf ein Druck ausgeübt wird, der das Piezoelement (21) aktiviert und einen Strom zur Sendeeinheit (13) fließen läßt, wodurch der Sender aktiviert und zur Sendung eines Signals veranlaßt wird.
Die Handhaben können in allen Fällen auch als Klappgriffe oder Druckhandhaben, wie sie an Kofferraumdeckeln oder Innenraumklappen und Handschuhkästen Anwendung finden, ausgeführt sein.
Die Ausführung des Piezoelements ist zudem als piezoelektrischer Lack denkbar, der auf die Oberfläche der Handhabe aufgebracht wird. Dadurch können Aussparungen (19,20) in der Handhabe (6) vermieden werden.
Diese Anordnungen haben allesamt den Vorteil, daß keine elektrischen Leitungen von beweglichen Handhaben (6) zum Fahrzeug verlegt sein müssen. Durch die Verwendung von piezoelektrischen Elementen (7,17,21) wird die Handhabe (6) zu einem autarkem System, wobei auch auf Energiespeicher, wie Batterien, verzichtet werden kann.In Fig. 1, a vehicle (1) is shown which is equipped with an electrical locking system. This locking system is intended to enable the authorized user of the vehicle (1) to access the vehicle (1) in a convenient and simple manner. In this embodiment, a door handle (3) and an electric lock (4) are arranged on each of the two doors (2), the door handles (3) being fastened to the door (2) by means of a support (4). The carrier (5) is mounted on the back of a door (2), which is fixed in position to the door panel by means of one or more screws. The handle (6) of the door handle (3), in this case a, is formed by recesses in the door panel (12) in the region of the carrier (5) Swivel handle in the form of a pull handle, connected to the carrier (5).
The handle (6) has sensors (7) which, when actuated, trigger an electrical signal, which are directed to a control unit (8) or the electrical locks (4). The sensors can be switching elements. Functions are triggered there, such as start of the identification query between a transmitter and receiver unit (9) and an ID transmitter carried by the user, electrical opening of the lock and thus the door (2), automatic closing of the entire locking system (central locking) when leaving the vehicle (1) or activating the double lock function, ie that the vehicle cannot be opened from the inside when it is locked.
From the carrier (5) of the door handle (3), the signals are transmitted via cable (10) to the control unit (8) or the door lock (4). A handle (3) with a corresponding carrier (5) and an electric lock (4) and handle (6) is also provided on the tailgate (11).
In Figure 2, a device according to the invention is shown as a schematic diagram. The device has a handle (6) in the form of a pull handle. This pull handle is mounted in a handle support (5) which is mounted on the inside of an outer door panel (12). The handle bracket (5) usually has the task of storing the handle and other lever and release elements, such as crash lock, Bowden cable mounts and bellcranks, which are used to mechanically release locks by actuating the handle (6). The handle (6) is mounted in two places in the handle support (5). On the one hand at the rear bearing (15), where the pull handle (3) can be pivoted about an axis that is almost vertical, and on the other hand at the front bearing (18). By pulling the handle (6), a lock (4) in the door (2) of the vehicle (1) is actuated directly or indirectly via a pulling element (16). The pull element (16) can be a Bowden cable.
Two pressure sensors (7, 17) on a piezoelectric basis are integrated in the handle (6), these piezo elements being inserted into recesses (19, 20) in the handle (6).
Furthermore, in the handle (6) there is a transmitter module (13) which comprises a modulator and an antenna in order to convert a triggered signal into a transmitter To convert and send signal. In this case, the triggered signal is transmitted by radio using Bluetooth technology, the frequency being in the range from 1 to 3 GHz.
The receiver module (10) is integrated in the handle support (5).
In the event of the user actuating the door handle (3), pressure is exerted on the piezo element (7, 17) by the user's hand and a current flows which activates the transmitter module (13) so that a radio signal is transmitted. The transmitted signal is received by the receiving unit (14), back-modulated into an electrical signal and sent via a signal line / cable (10) to the central control unit (8) or directly to the lock (4), after which an associated lock (4) is actuated. or the locks (4) mentioned.
The signal sent by the transmitting unit (13) can be received by several receiving units (14), which can be integrated in the vehicle at different points, in order to simultaneously actuate locks or other components at several points. The transmitted signal can be received by all of the receiving units (14) arranged on the vehicle to activate a central locking function or only by certain receiving units (14) in the vehicle (1), for example on inside door handles to activate their decoupling in the double lock function ,
It is also conceivable that the signal sent by the transmitter unit (13) is received by the central transmitter and receiver unit (9), which, among other things, establishes communication with the ID transmitter, and is passed from there to the control unit (8) ,
FIG. 3 shows an alternative device according to the invention, which differs from the previously described embodiment in that the handle (6) is only equipped with a sensor (7) which, for example, causes the central locking to close when actuated. This sensor (7), designed as a mechanical button, acts on a piezoelectric element so that a pressure is exerted thereon, which activates the piezo element (21) and allows a current to flow to the transmitter unit (13), thereby activating the transmitter and transmitting one Signal is caused.
In all cases, the handles can also be used as folding handles or pressure handles, such as those on trunk lids or interior flaps and glove boxes Find application, be executed.
The design of the piezo element is also conceivable as a piezoelectric lacquer that is applied to the surface of the handle. This makes it possible to avoid cutouts (19, 20) in the handle (6).
All of these arrangements have the advantage that no electrical lines have to be laid from movable handles (6) to the vehicle. The use of piezoelectric elements (7, 17, 21) makes the handle (6) an autonomous system, and energy storage devices such as batteries can also be dispensed with.
Die Anwendung dieser System ist bei allen Arten von Türgriffen (2) mit ihren Handhaben (6) denkbar, insbesondere bei Schwenkgriffen von Türen und Druckhandhaben an Außen- und Innenklappen, wie Heckklappen und Handschuhkastenklappen. Zu den Schwenkhandhaben zählen Zieh- und Klappgriffe, als auch kombinierte Zieh-Klappgriffe.
Je nach Anzahl der geforderten Signale sind an der Handhabe eine Vielzahl von Sensorelemente mit zugehörigen Piezo-Elementen installiert. Diese können an verschiedensten Orten angebracht sein, wie an der Front-, Ober- und/oder Unterseite der Handhabe (6).
In einer alternativen Ausführung ist an der Handhabe zur Signalauslösung mindestens ein Sensor (7) integriert, sowie mindestens ein zusätzliches Piezoelement, das lediglich zur Aktivierung der Sendeeinheit (13) aktiviert werden muß. Dies kann notwendig sein, wenn große Energien zur Signalübertragung benötigt werden. In diesem Fall sind Signalstrom und Energiestrom in Gegensatz zu den vorher beschriebenen Beispielen nicht identisch.The use of this system is conceivable for all types of door handles (2) with their handles (6), in particular for pivoting handles of doors and pressure handles on outer and inner flaps, such as tailgates and glove box flaps. The swivel handles include pulling and folding handles as well as combined pulling and folding handles.
Depending on the number of signals required, a large number of sensor elements with associated piezo elements are installed on the handle. These can be attached to a wide variety of locations, such as on the front, top and / or bottom of the handle (6).
In an alternative embodiment, at least one sensor (7) is integrated in the handle for triggering the signal, and at least one additional piezo element, which only has to be activated to activate the transmitter unit (13). This can be necessary if large energies are required for signal transmission. In this case, signal current and energy flow are not identical in contrast to the examples described above.
