Description
DESCRIPCIÓNDESCRIPTION
Cilindro de cierre para una llave electrónicaLock cylinder for an electronic key
La invención se refiere a un cilindro de cierre para una llave electrónica, con un núcleo móvil dentro de una carcasa, con un canal de bloqueo dispuesto en el núcleo para introducir la llave y una antena dispuesta en la carcasa para registrar las señales electrónicas de la llave y con un dispositivo electrónico de bloqueo para bloquear o liberar a elección el movimiento del núcleo en relación con las señales de la llave.The invention relates to a locking cylinder for an electronic key, with a movable core inside a housing, with a locking channel arranged in the core to insert the key and an antenna arranged in the housing to record the electronic signals of the key. key and with an electronic locking device to selectively block or release the movement of the core in relation to the key signals.
Este tipo de cilindro de cierre se conoce, por ejemplo, del documento DE 19906578 A1. La antena del cilindro de cierre rodea el núcleo, en cuyo canal de bloqueo se puede insertar un generador de códigos dispuesto en un eje la llave. El transmisor de código forma un circuito resonante con la antena, que puede ser usado para leer señales electrónicas sin contacto. La energía de activación para generar el circuito oscilante es inducida en el código transmisor por la antena. El transmisor del código está encapsulado en el plástico del eje de la llave.This type of locking cylinder is known, for example, from DE 19906578 A1. The antenna of the locking cylinder surrounds the core, in the locking channel of which a code generator arranged on a shaft can be inserted the key. The code transmitter forms a resonant circuit with the antenna, which can be used to read electronic signals without contact. The activation energy to generate the oscillating circuit is induced in the transmitting code by the antenna. The code transmitter is encapsulated in the plastic of the key shaft.
Sin embargo, la desventaja del conocido cilindro de cierre es que entre la antena y el generador de código está dispuesta una sección del núcleo y la carcasa del generador de código la llave. Esto resulta en una gran distancia de la antena respecto del generador de código. Sin embargo, una gran distancia entre la antena y el generador de código también produce un alto consumo de energía. Dado que el funcionamiento del cilindro de cierre debe garantizarse de la forma más independiente posible con su propio suministro de energía, el elevado consumo de energía hace que los intervalos de mantenimiento sean cortos.However, the disadvantage of the known locking cylinder is that a section of the core and the housing of the code generator is arranged between the antenna and the code generator. This results in a great distance from the antenna to the code generator. However, a large distance between the antenna and the code generator also produces high power consumption. Since the operation of the lock cylinder must be ensured as independently as possible with its own power supply, the high power consumption makes maintenance intervals short.
Se podría considerar colocar la antena en el núcleo directamente junto al canal de bloqueo. Dado que el dispositivo electrónico de bloqueo está dispuesto en la carcasa por razones de espacio, las señales de la antena, que se mueve junto con el núcleo, tendrían que ser transmitidas al dispositivo de bloqueo fijo, por ejemplo, por medio de contactos deslizantes. Sin embargo, estos contactos deslizantes son muy susceptibles a las interferencias. Además, estos contactos deslizantes tienen que ser guiados del núcleo a lo largo de toda la circunferencia, lo que conlleva un gran dispendio de construcción. La invención se basa en el problema de continuar desarrollando un cilindro de cierre del tipo mencionado al principio de manera tal que presente un consumo de energía particularmente bajo.One could consider placing the antenna in the core directly next to the blocking channel. Since the electronic locking device is arranged in the housing for reasons of space, the signals from the antenna, which moves together with the core, would have to be transmitted to the fixed locking device, for example by means of sliding contacts. However, these sliding contacts are very susceptible to interference. Furthermore, these sliding contacts have to be guided from the core along the entire circumference, which entails a great construction expense. The invention is based on the problem of continuing to develop a locking cylinder of the type mentioned at the beginning in such a way that it has a particularly low energy consumption.
Este problema se resuelve de acuerdo con la invención con las características de la reivindicación independiente 1. Mediante esta conformación, las señales y la energía de activación son transmitidas de forma inalámbrica entre el núcleo móvil y la carcasa fija. Pero la antena de transmisión en el núcleo y la antena en la carcasa se encuentran enfrentadas muy próximas una de la otra. Esto mantiene especialmente reducido el consumo de energía para la transmisión de las señales y la energía de activación.This problem is solved according to the invention with the features of independent claim 1. By this conformation, the signals and the activation energy are transmitted wirelessly between the moving core and the fixed housing. But the transmitting antenna in the core and the antenna in the housing are facing very close to each other. This keeps the energy consumption for the transmission of the signals and the activation energy especially low.
Los caminos de transmisión de las señales electrónicas de la llave, de acuerdo con la invención, se mantienen particularmente cortos, ya que la antena receptora en el núcleo está dispuesta directamente en el canal de bloqueo y está conectada con la antena de transmisión por medio de conductores eléctricos. Esto permite que la antena receptora se coloque de manera ventajosa en el canal de bloqueo en el que hay un chip transpondedor o una antena transmisora conectada al chip transpondedor de la llave insertada en el canal de bloqueo.The transmission paths of the electronic signals of the key, according to the invention, are kept particularly short, since the receiving antenna in the core is arranged directly in the blocking channel and is connected to the transmitting antenna by means of electric conductors. This allows the receiving antenna to be advantageously positioned in the locking channel in which there is a transponder chip or a transmitting antenna connected to the transponder chip of the key inserted in the locking channel.
La transmisión de la energía de activación a la antena receptora en el núcleo resulta particularmente sencilla de acuerdo con otro desarrollo ulterior ventajoso de la invención, cuando la antena de transmisión en el núcleo y la antena en la carcasa presenta bobinas. Por medio de esta conformación, la energía de activación puede ser transferida inductivamente. Las pérdidas en la transmisión de la energía de activación o de las señales de la llave pueden mantenerse particularmente bajas de acuerdo con otro desarrollo ulterior ventajoso de la invención, cuando las bobinas de la antena de transmisión en el núcleo y de la antena en la carcasa están dispuestas concéntricamente una de otra.The transmission of the activation energy to the receiving antenna in the core is particularly simple according to a further advantageous development of the invention, when the transmitting antenna in the core and the antenna in the housing have coils. By means of this conformation, the activation energy can be transferred inductively. The losses in the transmission of the activation energy or of the signals of the key can be kept particularly low according to another advantageous further development of the invention, when the coils of the transmitting antenna in the core and of the antenna in the housing they are arranged concentrically from each other.
Según otro desarrollo ventajoso de la invención, contribuye a una mayor reducción de las pérdidas en la transmisión de la energía de activación y las señales si la antena receptora tiene una bobina que rodea concéntricamente el canal de bloqueo.According to another advantageous development of the invention, it contributes to a greater reduction of the losses in the transmission of the activation energy and the signals if the receiving antenna has a coil that concentrically surrounds the blocking channel.
De acuerdo con otro desarrollo ulterior de la invención, el cilindro de la cerradura puede ser protegido contra los intentos de destrucción, si la antena está distanciada respecto del lado frontal de la carcasa. Las guarniciones de protección frecuentemente se disponen del lado frontal del cilindro de la cerradura y, por tanto, en el frente de la carcasa, para proteger el cilindro de cierre, por ejemplo, contra la perforación u otra destrucción mecánica. Pero estas guarniciones de protección amortiguan e interfieren con los campos eléctricos y por lo tanto con la transmisión de señales a la antena en la carcasa. Debido a la disposición de la antena, que se encuentra a distancia del lado frontal de la carcasa se evita la interferencia en la transmisión de señales mediante las guarniciones de protección.According to a further development of the invention, the lock cylinder can be protected against destruction attempts, if the antenna is spaced from the front side of the housing. Protective trims are often provided on the front side of the lock cylinder, and thus on the front of the housing, to protect the lock cylinder, for example, against perforation or other mechanical destruction. But these protective gaskets damp and interfere with electric fields and therefore with the transmission of signals to the antenna in the housing. Due to the arrangement of the antenna, which is located at a distance from the front side of the housing, interference in the signal transmission is avoided by the protective covers.

Estas bobinas 19, 20 pueden ser usadas para transmitir energía de activación inductivamente para leer el generador de códigos 16. Figure 2 shows the closing cylinder of Figure 1 in a sectional view along the line II-II. It can be seen that the antenna 8 in the housing 2 and the transmitting antenna 11 in the core 3 each have coils 19, 20. These coils 19, 20 can be used to transmit drive energy inductively to read the code generator 16 .
