Abstract
Ein Schließzylinder (1) für einen elektronischen Schlüssel (6) hat einen Kern (3) mit einer einen Codegeber (16) des Schlüssels (6) umschließenden Empfangsantenne (13) und eine nahe am Gehäuse (2) angeordnete Übertragungsantenne (11). Die Empfangsantenne (13) und die Übertragungsantenne (11) sind über elektrische Leiter (12) miteinander verbunden. Hierdurch werden drahtlose Übertragungswege von Signalen und Aktivierungsenergie besonders kurz gehalten.A locking cylinder (1) for an electronic key (6) has a core (3) with a receiving antenna (13) surrounding a code transmitter (16) of the key (6) and a transmission antenna (11) arranged close to the housing (2). The receiving antenna (13) and the transmission antenna (11) are connected to one another via electrical conductors (12). As a result, wireless transmission paths of signals and activation energy are kept particularly short.
Description
Die Erfindung betrifft einen Schließzylinder für einen elektronischen Schlüssel, mit einem in einem Gehäuse beweglichen Kern, mit einem im Kern angeordneten Schließkanal zur Einführung des Schlüssels und einer im Gehäuse angeordneten Antenne zur Erfassung von elektronischen Signalen des Schlüssels und mit einer elektronischen Sperreinrichtung zur wahlweisen Blockierung oder Freigabe der Bewegung des Kerns in Abhängigkeit von den Signalen des Schlüssels.The invention relates to a lock cylinder for an electronic key, with a core movable in a housing, with a core arranged in the lock channel for insertion of the key and an antenna disposed in the housing for detecting electronic signals of the key and with an electronic locking device for optional blocking or Releasing the movement of the core as a function of the signals of the key.
Ein solcher Schließzylinder ist beispielsweise aus der
Nachteilig bei dem bekannten Schließzylinder ist jedoch, dass zwischen der Antenne und dem Codegeber ein Abschnitt des Kerns und die Ummantelung des Codegebers des Schlüssels angeordnet sind. Dies führt zu einem großen Abstand der Antenne von dem Codegeber. Ein großer Abstand zwischen Antenne und Codegeber führt jedoch auch zu einem hohen Energieverbrauch. Da die Funktion des Schließzylinders jedoch mit einer eigenen Energieversorgung möglichst unabhängig sichergestellt sein soll, führt der hohe Energieverbrauch zu kurzen Wartungsintervallen.A disadvantage of the known lock cylinder, however, that between the antenna and the code transmitter, a portion of the core and the sheath of the code transmitter of the key are arranged. This leads to a large distance of the antenna from the encoder. However, a large distance between antenna and encoder also leads to high energy consumption. However, since the function of the lock cylinder should be ensured as independent as possible with its own power supply, the high energy consumption leads to short maintenance intervals.
Man könnte daran denken, die Antenne im Kern unmittelbar an dem Schließkanal anzuordnen. Da die elektronische Sperreinrichtung aus Platzgründen im Gehäuse angeordnet ist, müssten die Signale von der mit dem Kern mitbewegenden Antenne beispielsweise mittels Schleifkontakte zu der feststehenden Sperreinrichtung übertragen werden. Solche Schleifkontakte sind jedoch sehr störanfällig. Weiterhin müssen solche Schleifkontakte über den gesamten Umfang des Kerns geführt werden, was zu einem hohen baulichen Aufwand führt.One might think of arranging the antenna in the core directly on the closing channel. Since the electronic locking device is arranged in the housing for reasons of space, the signals would have to be transmitted from the antenna moving along with the core, for example by means of sliding contacts, to the stationary locking device. Such sliding contacts are very susceptible to interference. Furthermore, such sliding contacts must be performed over the entire circumference of the core, resulting in a high construction cost.
Der Erfindung liegt das Problem zugrunde, einen Schließzylinder der eingangs genannten Art so weiter zu bilden, dass er einen besonders geringen Energieverbrauch aufweist.The invention is based on the problem to further develop a lock cylinder of the type mentioned so that it has a very low energy consumption.
Dieses Problem wird erfindungsgemäß dadurch gelöst, dass der Antenne im Gehäuse eine Übertragungsantenne im Kern zur berührungslosen Übertragung der Signale des Schlüssels unmittelbar gegenübersteht.This problem is inventively solved in that the antenna in the housing directly opposite a transmission antenna in the core for non-contact transmission of the signals of the key.
Durch diese Gestaltung werden Signale und Aktivierungsenergie zwischen dem beweglichen Kern und dem feststehenden Gehäuse drahtlos übertragen. Die Übertragungsantenne im Kern und die Antenne im Gehäuse stehen jedoch einander dicht gegenüber. Damit wird der Energieverbrauch zur Übertragung der Signale und der Aktivierungsenergie besonders gering gehalten.With this configuration, signals and activation energy are transmitted wirelessly between the movable core and the fixed case. However, the transmitting antenna in the core and the antenna in the case are close to each other. Thus, the energy consumption for transmitting the signals and the activation energy is kept very low.
Übertragungswege der elektronischen Signale des Schlüssels lassen sich gemäß einer vorteilhaften Weiterbildung der Erfindung besonders kurz halten, wenn eine Empfangsantenne in dem Kern unmittelbar am Schließkanal angeordnet ist und mit der Übertragungsantenne über elektrische Leiter verbunden ist. Hierdurch lässt sich die Empfangsantenne in vorteilhafter Weise an der Stelle am Schließkanal positionieren, an der sich ein Transponderchip oder eine mit dem Transponderchip verbundene Sendeantenne des in den Schließkanal eingeführten Schlüssels befindet.Transmission paths of the electronic signals of the key can be kept particularly short according to an advantageous embodiment of the invention, when a receiving antenna is arranged in the core directly on the closing channel and is connected to the transmission antenna via electrical conductors. As a result, the receiving antenna can advantageously be positioned at the location on the closing channel at which a transponder chip or a transmitting antenna connected to the transponder chip of the key inserted into the closing channel is located.
Eine Übertragung von Aktivierungsenergie zu der Empfangsantenne im Kern gestaltet sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung besonders einfach, wenn die Übertragungsantenne im Kern und die Antenne im Gehäuse Spulen aufweisen. Durch diese Gestaltung lässt sich die Aktivierungsenergie induktiv übertragen.A transmission of activation energy to the receiving antenna in the core is particularly simple according to another advantageous embodiment of the invention, when the transmission antenna in the core and the antenna in the housing have coils. This design allows the activation energy to be transmitted inductively.
Verluste bei der Übertragung der Aktivierungsenergie oder von Signalen des Schlüssels lassen sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung besonders gering halten, wenn die Spulen der Übertragungsantenne im Kern und der Antenne im Gehäuse konzentrisch zueinander angeordnet sind.Losses in the transmission of the activation energy or signals of the key can be kept particularly low according to another advantageous embodiment of the invention, when the coils of the transmission antenna in the core and the antenna in the housing are arranged concentrically to each other.
Zur weiteren Verringerung von Verlusten bei der Übertragung von Aktivierungsenergie und Signalen trägt es gemäß einer anderen vorteilhaften Weiterbildung der Erfindung bei, wenn die Empfangsantenne eine den Schließkanal konzentrisch umschließende Spule hat.To further reduce losses in the transmission of activation energy and signals, it contributes according to another advantageous embodiment of the invention, when the receiving antenna has a coil surrounding the closing channel concentric.
Der Schließzylinder lässt sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung mit Schutzbeschlägen gegen einen Zerstörungsversuch sichern, wenn die Antenne von der Stirnseite des Gehäuses beabstandet ist. Schutzbeschläge werden häufig an der Stirnseite des Schließzylinders und damit an der Stirnseite des Gehäuses angeordnet, um den Schließzylinder beispielsweise vor einem Aufbohren oder anderer mechanischer Zerstörung zu schützen. Solche Schutzbeschläge dämpfen und stören jedoch elektrische Felder und damit die Übertragung der Signale zu der Antenne im Gehäuse. Durch die von der Stirnseite entfernte Anordnung der Antenne wird eine Störung der Übertragung der Signale durch die Schutzbeschläge vermieden.The lock cylinder can be secured according to another advantageous embodiment of the invention with protective fittings against a destruction attempt, when the antenna is spaced from the front side of the housing. Protective fittings are often arranged on the front side of the lock cylinder and thus on the front side of the housing to protect the lock cylinder, for example, against drilling or other mechanical destruction. However, such protective fittings damp and disturb electrical fields and thus the transmission of the signals to the antenna in the housing. By the remote from the front of the antenna arrangement, a disturbance of the transmission of the signals through the protective fittings is avoided.

Diese zeigt inThe invention allows numerous embodiments. To further clarify its basic principle, one of them is shown in the drawing and will be described below. This shows in
