Definitions

  • the invention relates to a lock cylinder for an electronic key, with a movable core in a housing, with a locking channel arranged in the core for introducing the key and an antenna arranged in the housing for detecting electronic signals from the key and with an electronic locking device for optional blocking or locking Release of the movement of the core depending on the signals of the key, with electrical contacts for contacting corresponding contacts on the key being arranged in the core, the electrical contacts of the core via electrical conductors with a transmission antenna arranged in the core for transmitting the signals of the key to the antenna are connected in the housing and the transmission antenna in the core and the antenna in the housing have coils.
  • a mechatronic locking device which discloses an at least partially electronic key which has a contact means on its shaft which is designed for signal transmission between the key and a core of a lock cylinder with a second contact means arranged in the core.
  • the signal transmission can only take place when the two contact means come into direct contact.
  • a similar lock cylinder is still from the DE 199 06 578 A1 known.
  • the antenna of the lock cylinder surrounds the core, in whose lock channel an in a shaft of the key arranged code transmitter can be introduced.
  • the code generator and the antenna form an oscillating circuit via which electronic signals can be read out without contact.
  • the activation energy for generating the resonant circuit is induced by the antenna into the encoder.
  • the code transmitter is encased in a plastic of the shaft of the key.
  • the disadvantage of the known lock cylinder is that a section of the core and the sheathing of the code generator of the key are arranged between the antenna and the code transmitter. This leads to a large distance between the antenna and the encoder. However, a large distance between the antenna and the encoder also leads to high energy consumption. However, since the function of the locking cylinder should be ensured as independently as possible with its own energy supply, the high energy consumption leads to short maintenance intervals.
  • the invention is based on the problem of developing a lock cylinder of the type mentioned at the beginning in such a way that it has a particularly low energy consumption.
  • This design makes it possible to keep losses in the transmission of activation energy or signals from the key particularly low.
  • the lock cylinder has a particularly low energy consumption when the transmission antenna in the core and the antenna in the housing for contactless transmission of the signals of the key are directly opposite one another.
  • a particularly reliable connection of the code generator in the key to the electrical conductors in the core can be produced if the contacts of the core are biased against the contacts of the key.
  • the lock cylinder can be secured against attempted destruction with protective fittings if the antenna is spaced from the end face of the housing.
  • Security fittings are often on the face of the lock cylinder and thus on the face of the housing arranged to protect the lock cylinder, for example, from drilling open or other mechanical destruction.
  • such protective fittings dampen and disrupt electrical fields and thus the transmission of the signals to the antenna in the housing.
  • Figure 1 shows a lock cylinder 1 with a core 3 rotatably mounted in a housing 2.
  • the core 3 is connected to a lock bit 4 in a rotationally fixed manner. At its end faces, the core 3 has a locking channel 5 for inserting a key 6.
  • the lock cylinder 1 has an electromagnetic locking device 7 for optionally blocking or releasing the movement of the core 3 with respect to the housing 2.
  • An antenna 8 is arranged in a region of the housing 2 remote from the end face of the lock cylinder 1.
  • the antenna 8 is connected to a control device 9 which controls the electromagnetic blocking device 7.
  • an energy store 10 designed as a button cell is also arranged.
  • the energy store 10 supplies the control device 9 and the locking device 7 with electrical energy.
  • a transmission antenna 11 of the core 3 faces the antenna 8 in the housing 2 at a small distance and is connected to resilient contacts 13 via electrical conductors 12.
  • the key 6 has a shaft 14 designed corresponding to the locking channel 5 and a bow 15 as a handle.
  • a code transmitter 16 for example in a plastic potting compound, is arranged in the shaft 14 of the key 6.
  • the code generator 16 is connected via electrical conductors 17 to fixed contacts 18 arranged on the outer surface of the shaft 14.
  • the resilient contacts 13 of the core 3 are biased against the stationary contacts 18 of the key 6.
  • Figure 2 shows the lock cylinder Figure 1 in a sectional view along the line II-II. It can be seen here that the antenna 8 in the housing 2 and the transmission antenna 11 in the core 3 each have coils 19, 20. Activation energy for reading out the code transmitter 16 can be inductively transmitted via these coils 19, 20.
