Die Betätigungsvorrichtung wird bei Kraftfahrzeugen eingesetzt und
dient dazu, beispielsweise ein Heckfenster 37 (Fig. 3 und 4) eines
Kraftfahrzeuges zu entriegeln. Die Betätigungsvorrichtung kann aber
auch zum Öffnen eines Kofferraumdeckels, einer Motorhaube oder
eines Handschuhfaches eines Kraftfahrzeuges eingesetzt werden. Im
dargestellten Ausführungsbeispiel dient die Betätigungsvorrichtung
zum Entriegeln einer Heckscheibe 37 eines Kraftfahrzeuges, die in
einer schwenkbaren Heckklappe 38 vorgesehen ist. Nach dem Entriegeln
kann die Heckscheibe 37 gegenüber der Heckklappe 38 gesondert
hochgeschwenkt werden.The actuator is used in motor vehicles and
serves, for example, a rear window 37 (FIGS. 3 and 4)
Unlock motor vehicle. The actuator can
also for opening a trunk lid, a bonnet or
a glove compartment of a motor vehicle are used. in the
illustrated embodiment serves the actuator
for unlocking a
An der Heckscheibe 37 des Kraftfahrzeuges ist ein Empfänger 39 mit
einem Taster 1 vorgesehen, der an eine Planarantenne 2 angeschlossen
ist. Sie wird über ein Abgleichelement 3 auf eine vorgegebene
Resonanzfrequenz abgestimmt. Im einfachsten und bevorzugten
Fall wird das Abgleichelement 3 durch zwei parallel liegende
Kondensatoren 4, 5 gebildet. Sie können einstellbar sein.A
Um die Heckscheibe 37 hochzuklappen, wird der Taster 1 gedrückt
und damit der Resonanzkreis 6 geschlossen. Im Beispielsfall beträgt
die Resonanzfrequenz 13.560 MHz. Je nach Einsatzfall kann die Resonanzfrequenz
auch anders gewählt sein. In order to fold up the
Der Resonanzkreis 6 mit der Planarantenne 2 und dem Taster 1 bildet
eine passive Antenne. Sie muß nicht mit Strom versorgt werden.The
Sobald der Resonanzkreis 6 durch Drücken des Tasters 1 geschlossen
wird, wird einer in einem Sender 7 der Betätigungsvorrichtung
befindlichen Sendeantenne 8 Energie entzogen. Dadurch wird die
Amplitude eines nachgeschalteten Oszillators 9 an einem hochohmigen
Auskoppelungspunkt 10 eines Quarzes 11 herabgesetzt. Die
Hochfrequenzspannung wird an einem Hochfrequenzgleichrichter 12
gleichgerichtet und dem Minuseingang eines Komparators 13 zugeführt.
Aufgrund des Amplitudenabfalles am Auskoppelungspunkt 3
sinkt der Pegel am Plusausgang 14 des dem Gleichrichter 12 nachgeschalteten
Komparators 13, so daß am Ausgang 14 des Komparators
13 das entsprechende Steuersignal zur Entriegelung des Heckscheibenfensters
ansteht.As soon as the
Die Batteriespannung, die im Beispielsfall 12 Volt beträgt, wird mittels
eines Spannungsreglers 15 stabilisiert, im Ausführungsbeispiel
auf 7 Volt. Dem Eingang und dem Ausgang des Reglers 15 ist jeweils
ein Widerstand 35 und 36 zugeordnet. Das am Ausgang des Reglers
15 anliegende Signal wird dem Pluseingang des Komparators 13 zugeführt,
der das Reglersignal mit dem gleichgerichteten Ausgangssignal
des Oszillators 9 vergleicht und das Steuersignal liefert.The battery voltage, which in the example is 12 volts, is determined by
a
Der Oszillator 9 hat einen Transistor 16, der über den Quarz 11 in
Resonanzfrequenz vorzugsweise 13,560 MHz (ISM-Band) zur Sendeantenne
8 gebracht wird. Sie ist vorteilhaft eine Planarantenne. Ihr
nachgeschaltet sind zwei in Reihe geschaltete Widerstände 17, 18,
die einen Spannungsteiler zur Basis bzw. zum Arbeitspunkt des
Transistors 16 bilden. Parallel zum Widerstand 17 bzw. in Reihe zum
Widerstand 18 liegen zwei Kondensatoren 19, 20, die für die Rückkoppelung
verantwortlich sind, um die Schwingungsamplitude zu erzeugen.
Ein Widerstand 21 bestimmt den Emitterstrom zum Transistor
16.The
Der Oszillator 9 ist mit einem Tiefpaß 22 versehen, um von außen
kommende Störstrahlungen auszusieben. Der Tiefpaß 22 besteht aus
einem Widerstand 23, dem ein Kondensator 24 und ein Widerstand
25 nachgeordnet sind. Der Widerstand 25 ist in den Kollektorkreis
des Transistors 16 geschaltet und liegt in Reihe zum Widerstand 18
des Spannungsteilers.The
Der Gleichrichter 12 ist vorteilhaft temperaturkompensiert, so daß
sich bei Temperaturschwankungen die Offset-Spannung des Komparatoreinganges
nicht verändert. Hierzu ist der Gleichrichter 12 mit
zwei zu einer Einheit zusammengefaßten Dioden 26, 27 versehen,
die thermisch auf einem Chip integriert sind. Die Auskopplungsstelle
10 am Oszillator 9 wird durch einen Kondensator gebildet, der so
eingestellt ist, daß die Spannung noch so hoch ist, daß sie die
Schwellspannung des Gleichrichters 12 ausreichend weit übersteigt,
um eine zuverlässige Auswertung im Komparator 13 zu ermöglichen.The
Dem Auskoppelungspunkt 10 des Oszillators 9 ist ein Tiefpaß 28, 29
nachgeschaltet, um HF-Störungen von außen zu unterdrücken, die zu
einer ungewollten Betätigung der Steuerung führen könnten. Der
Tiefpaß hat die Induktivität 28 und den Kondensator 29, die den Dioden
26, 27 vorgeschaltet sind.The
Im dargestellten Ausführungsbeispiel ist sowohl dem Plus- als auch
dem Minuseingang des Komparators 13 jeweils ein Tiefpaß vorgeschaltet.
Der dem Pluseingang zugeordnete Tiefpaß besteht aus einem
Widerstand 30 und einem nachgeschalteten Kondensator 31.
Der dem Minuseingang des Komparators 13 zugeordnete Tiefpaß hat
den Widerstand 32 und den nachgeschalteten Kondensator 33. Die
beiden Widerstände 30, 32 und die beiden Kondensatoren 31, 33 haben
gleiche Kenndaten. An dem Komparatorausgang 14 kann eine
niederohmige Last 34 betrieben werden.In the illustrated embodiment, both the plus and
A low-pass filter is connected upstream of the negative input of the
Durch Drücken des Tasters 1 des Passivelementes wird der Resonanzkreis
3 geschlossen, wodurch dem Sender 7 Energie entzogen
wird. Sie führt zum Auslösen eines Steuersignales, wodurch die Entriegelung
des Heckfensters 37 erreicht wird. Die Übertragung zwischen
dem passiven Element und dem Sender 7 erfolgt unter Ausnutzung
der Resonanzfrequenz leitungs- bzw. drahtlos. Der passive
Sekundärkreis 6, der auf die Sendefrequenz abgestimmt bzw. über
den Taster 1 gegen die Sendefrequenz verstimmt ist, entzieht dem
Oszillator 9 im Resonanzfall ausreichend Energie, so daß der Abfall
der HF-Spannung über den HF-Gleichrichter 12 auf die folgende
Komparatorschaltung erfaßt wird. Sie liefert am Ausgang 14 ein entsprechendes
Logiksignal zur Steuerung eines Leistungs-FET-Schalters
40, mit dem die Entriegelung des Heckfensters 37 erreicht
wird.By pressing the
Aufgrund der drahtlosen Entriegelung des Heckfensters 37 ohne Verwendung
von Leitungen, Kabeln und dergleichen ergibt sich eine sehr
einfache Montage der Betätigungsvorrichtung. Sie ist nicht störanfällig
und ist insbesondere verschleißfrei. De Sender 7 benötigt nur
einen minimalen Strom, der beispielsweise nur etwa 3 mA beträgt.
Dadurch kann der Sender 7 auch über lange Zeit hinweg in Bereitschaftsstellung
sein, ohne daß dadurch der Fahrzeugbatterie, an
welche der Sender angeschlossen ist, zu viel Energie entzogen wird.Due to the wireless unlocking of the
Vorteilhaft ist es, den Sender 7 mit der Zentralverriegelung des Kraftfahrzeuges
zu koppeln. Ist das Fahrzeug zentralverriegelt, ist auch
der Sender 7 ausgeschaltet, so daß er keinen Strom benötigt. Wird
die Zentralverriegelung geöffnet, wird auch der Sender 7 eingeschaltet,
so daß er betriebsbereit ist. Wird der Sender 7 über die Zentralverriegelung
abgeschaltet, besteht für Unbefugte keine Möglichkeit,
von außen den Sender 7 zu manipulieren und das Heckfenster 37
unbefugt zu öffnen.It is advantageous to the
Fig. 5 zeigt einen Sender 7, bei dem der Quarz 11 in Resonanz mit
einem Teil der Antenne 8 und an sie angeschlossenen Kondensatoren
41, 42 ist. Dadurch wird die Belastung des Quarzes 11 gering
gehalten. Durch die Anzapfung der Antenne 8 (Spule) entsteht am
oberen Spulenabgriff eine höhere Nutzamplitude. Dadurch kann die
Empfindlichkeit bei gleichzeitig geringer Quarzbelastung gesteigert
werden.Fig. 5 shows a
Im übrigen ist der Sensor im wesentlichen gleich ausgebildet wie bei der vorigen Ausführungsform. Er arbeitet gleich wie beim vorhergehenden Ausführungsbeispiel.Otherwise, the sensor is essentially the same as in the previous embodiment. It works the same as the previous one Embodiment.
