Definitions

  • the invention relates to an electronic locking device, in particular an electronic locking cylinder.
  • the coupling means comprise a coupling element that rotates with the rotor upon actuation and thereby moves away from the coupling and/or locking means.
  • locking devices are also known that comprise a locking element movable via a spring, with which the rotor can be locked against the stator.
  • these have the additional disadvantage that they cannot be used to couple the rotor to the output device.
  • the object of the present invention is to create a locking device that overcomes the disadvantages of the prior art.
  • the locking device should be simple in design, not place high demands on the control system, and be tamper-proof.
  • the rotor can be freely rotatable in the stator in the uncoupled state without affecting the locking state, or it can be additionally locked against the stator.
  • the rotor can also be rigidly coupled to the output element or form the output element.
  • the coupling element is guided by a bearing sleeve.
  • this can be designed to deform in the event of an overload, thereby allowing the coupling element to deflect, for example, by eliminating the self-locking effect after deformation of the bearing sleeve.
  • This targeted weak point allows for relatively simple and cost-effective repair of the locking device after excessive force has been applied, without compromising the locking device's security.
  • the endless spindle can have a globoid shape to compensate for the angle of rotation of the spring leg engaging it without requiring an excessively large thread depth. This provides an advantage in terms of compactness, which is in turn advantageous because the drive is located in the rotor according to the inventive concept.
  • an advantage of the inventive approach in combination with the use of an endless spindle is that the coupling mechanism functions flawlessly even when the state of the locking device is unknown and/or not precisely defined. Nevertheless, during a (rotary) movement of the drive in the opening or closing direction, the drive is never subjected to excessive load, and the problem of excessive energy consumption never arises. For example, it can be provided that the drive performs a predetermined number of revolutions with each opening or closing command from the control electronics. After completing this predetermined number of revolutions, the locking device is always in a defined and known state, even if the initial state was previously unknown – e.g., due to an interruption in the power supply.
  • the clutch element can have a permanent magnet or a magnetic field sensor that interacts with a magnetic field sensor or permanent magnet of an element stationary with respect to the rotor housing, e.g., a Hall sensor arranged on the electronics carrier (printed circuit board) of the rotor.
  • a Hall sensor arranged on the electronics carrier (printed circuit board) of the rotor.
  • Another possible sensor for detecting the state is a suitably arranged mechanically actuated switch in the rotor.
  • the coupling element 15 in addition to the recess for the leg 14.2 of the leg spring, also has a recess for a permanent magnet 31. This can interact with a Hall sensor (not shown) on the electronics carrier, allowing the locking state to be determined. As explained at the beginning, however, this is an optional feature due to the procedure described here: the functional principle of the locking device does not require knowledge of the locking state.
  • the endless spindle 13 is globoid, with an outer and an inner contour that deviates from the cylindrical shape and is curved outwardly. This allows the first leg 14.1 of the torsion spring to engage the coils and follow the contour line during a rotational movement around the axis of the bearing pin 18. This in turn means that the thread depth does not have to significantly exceed the thickness of the spring leg, while still ensuring reliable guidance along the entire path along the spindle.
  • the globoid spindle thus saves space; a very compact design is possible.
  • Figure 6 illustrates the state in which the drive has received a coupling signal and has moved the first leg accordingly by means of the endless spindle 13.
  • the coupling element is blocked and cannot move into the coupling state because the rotor is not aligned with the coupling recesses of the output element in the illustrated state.
  • the spring 14 is consequently tensioned by moving the leg 14.1 into the state according to Figure 6 is moved.
  • the locking device can also be moved directly from the uncoupled state to the state according to Figure 7 skip.
  • Figure 10 shows the output sleeve. It has a plurality of coupling recesses 8.1 on the inside, into which the coupling projection of the coupling element can engage.
  • the output element can also be manufactured in one piece, ie output sleeve 8 and driver 9 are formed by a single component.
