Description
Die Erfindung bezieht sich auf eine Vorrichtung zur Erfassung des Betriebszustands einer z.B. an einer Fenster-, Tür-, Heckklappen- oder anderen Fahrzeugöffnung angeordneten Schlauchdichtung, mit einer Sendeeinheit, die an einem Ende der Schlauchdichtung angeordnet und mittels der ein Schallsignal in den Innenraum der Schlauchdichtung abstrahlbar ist, einer Empfangseinheit, mittels der das von der Sendeeinheit in den Innenraum der Schlauchdichtung abgestrahlte Schallsignal empfangbar ist, und einer Auswerteeinheit, die mit der Sendeeinheit und der Empfangseinheit verbunden und mittels der ein Messwert der Empfangseinrichtung auswertbar ist.The invention relates to a device for detecting the operating condition of e.g. arranged on a window, door, tailgate or other vehicle opening hose seal, with a transmitting unit, which is arranged at one end of the hose seal and by means of a sound signal in the interior of the hose seal can be emitted, a receiving unit, by means of which of the transmitting unit in the sound emitted to the interior of the hose seal sound signal, and an evaluation unit, which is connected to the transmitting unit and the receiving unit and by means of which a measured value of the receiving device can be evaluated.
Eine derartige Vorrichtung zur Erfassung des Betriebszustands einer Schlauchdichtung ist beispielsweise aus der
Der Erfindung liegt die Aufgabe zugrunde, die eingangs geschilderte Vorrichtung zur Erfassung des Betriebszustands einer Schlauchdichtung derart weiterzubilden, dass sie mit einem geringeren technisch-konstruktiven Aufwand herstellbar ist, eine höhere Betriebssicherheit bietet und aussagekräftigere Messergebnisse zur Verfügung stellt.The invention has the object of developing the above-described device for detecting the operating state of a hose seal such that it can be produced with a lower technical and design effort, provides greater reliability and provides more meaningful measurement results.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass die Sendeeinheit dieser Vorrichtung zur Abstrahlung eines als Ultraschallsignal ausgebildeten Schallsignals ausgestaltet ist, dass die Vorrichtung ein Reflektorelement aufweist, das an dem der Sendeeinheit entgegengesetzten Ende der Schlauchdichtung angeordnet und mittels dem das von der Sendeeinheit abgestrahlte Ultraschallsignal zur Sendeeinheit reflektierbar ist, und dass die Empfangseinheit an der Sendeeinheit angeordnet ist. Durch die Ausgestaltung der Sendeeinheit zur Abstrahlung eines Ultraschallsignals lässt sich im Vergleich zum Stand der Technik die Betriebssicherheit der Vorrichtung erhöhen. Mittels der gemeinsamen Anordnung von Sende- und Empfangseinheit ist eine Vereinfachung des Aufbaus der Vorrichtung realisierbar. Mittels des Reflektorelements wird eine Funktionsweise der erfindungsgemäßen Vorrichtung gemäß dem Ultraschall-Echolotprinzip verwirklicht, die eine hohe Betriebssicherheit und aussagekräftige Messwerte sicherstellt. Eine besonders zweckmäßige Gestaltung der erfindungsgemäßen Vorrichtung zur Erfassung des Betriebszustands einer Schlauchdichtung ist erreichbar, wenn das Reflektorelement der Vorrichtung durch ein geschlossenes Schlauchende gebildet ist.This object is achieved in that the transmitting unit of this device is designed to emit a sound signal designed as an ultrasonic signal, that the device has a reflector element, which is arranged at the end of the hose seal opposite the transmitting unit and by means of the emitted from the transmitting unit ultrasonic signal to the transmitting unit is reflective, and that the receiving unit is arranged on the transmitting unit. The design of the transmitting unit for emitting an ultrasonic signal can increase the reliability of the device in comparison to the prior art. By means of the common arrangement of transmitting and receiving unit a simplification of the structure of the device can be realized. By means of the reflector element, an operation of the device according to the invention is realized according to the ultrasonic echosounder principle, which ensures a high degree of operational reliability and meaningful measured values. A particularly expedient design of the device according to the invention for detecting the operating state of a hose seal can be achieved if the reflector element of the device is formed by a closed hose end.
Wenn die Auswerteeinheit der Vorrichtung ein Zeitglied aufweist, mittels dem ein Zeitintervall zwischen der Abstrahlung des Ultraschallsignals von der Sendeeinheit und dem Empfang des Ultraschallsignals an der Empfangseinheit erfassbar ist, wobei in der Auswerteeinheit das erfasste Zeitintervall mit einem Zeitintervall-Sollwert vergleichbar ist, lassen sich durch den Vergleich zwischen Zeitintervall und Zeitintervall-Sollwert Rückschlüsse darauf ziehen, an welcher Stelle der Schlauchdichtung eine Quetschung od.dgl. aufgetreten ist.If the evaluation unit of the device has a timing element, by means of which a time interval between the emission of the ultrasound signal from the transmitting unit and the reception of the ultrasound signal at the receiving unit can be detected, wherein the detected time interval in the evaluation unit is comparable to a time interval setpoint value draw the conclusions between time interval and time interval setpoint conclusions on which point of the hose seal a pinch or the like. occured.
Um bei den an der Empfangseinheit der Vorrichtung erfassten Messwerten die die Signalqualität und die Signalstärke beeinflussenden, von der aktuellen Temperatur abhängigen Parameter zu berücksichtigen, ist es vorteilhaft, wenn die Auswerteeinheit eine Temperaturkompensationseinheit aufweist, mittels der bei der Auswertung des Messwerts der Empfangseinheit die aktuelle Temperatur berücksichtigbar ist.In order to take into account the parameters which influence the signal quality and the signal strength, which depend on the current temperature in the measured values received at the receiving unit of the device, it is advantageous if the evaluation unit has a temperature compensation unit by means of which the current temperature is evaluated when the measured value of the receiving unit is evaluated is considered.
Um eine exakte Feststellung zu treffen, in welchem Schließzustand die mit der Schlauchdichtung versehene Fahrzeugöffnung sich befindet, ist es vorteilhaft, wenn in der Auswerteeinheit der Vorrichtung eine Dämpfung des von der Empfangseinheit empfangenen Ultraschallsignals erfassbar ist, wobei in der Auswerteeinheit aus der Dämpfung des Ultraschallsignals der freie Innenquerschnitt der Schlauchdichtung bzw. der Schließzustand der Fenster-, Tür-, Heckklappen- oder anderen Fahrzeugöffnung erfassbar ist.In order to make an exact determination in which closed state the vehicle opening provided with the hose seal is located, it is advantageous if an attenuation of the ultrasonic signal received by the receiving unit can be detected in the evaluation unit of the device, wherein in the evaluation unit from the attenuation of the ultrasonic signal free inner cross-section of the hose seal or the closed state of the window, door, tailgate or other vehicle opening is detected.
