Definitions

  • the invention relates to an actuator for an electric lock and to a method of actuating an electric lock.
  • the invention relates in particular to actuators and methods that may be used to couple a manually operable actuation element, such as a rotary knob, to a locking element, such as a latch or locking bolt.
  • Electric actuators may be provided in lock cylinders, door fittings, or electric locks for increased user convenience, safety, and control. Electric lock actuators may be used to displace a locking element, such as a latch or locking bolt, in response to a successful authentication of a user. Electric lock actuators may be used to selectively couple a manually operable actuation element, such as a door handle or rotary door knob, to a locking element.
  • An electric actuator for a lock should have a compact construction and should afford safety against manipulation attempts.
  • Electric actuators that comprise a spindle drive or other rotary-to-linear motion conversion mechanism have a compact construction.
  • Exemplary electric actuators for locks that convert a rotary motion of a motor output shaft to a linear displacement are described in, e.g., DE 10 2004 046778 B4 and EP 2 963 212 A1 .
  • Conventional electric actuators that comprise a spindle drive or other rotary-to-linear motion conversion mechanism may be prone to manipulation attempts in which torque or an angular momentum is applied to the electric actuator or a component to which the electric actuator is mounted.
  • exertion of a force onto the electric actuator or a component housing the electric actuator such as by hitting with a hammer or other mechanical tool, can create a torque pulse.
  • Inertia of components of the electric actuator that are rotatably mounted in a housing of the actuator such as a spindle of a spindle drive, can result in a relative rotary movement between the spindle and the housing of the actuator.
  • Repeated application of torque pulses bears the risk that the spindle drive can be manipulated, due to the relative rotary movement between the spindle and the housing of the actuator.
  • an electric actuator which comprises a rotatably mounted drive sub-unit and a rotatably mounted driven sub-unit.
  • the driven sub-unit may comprise or may be coupled to a spindle of a spindle drive.
  • the drive sub-unit and the driven sub-unit may have rotation axes which extend parallel to each other, but which are offset from each other.
  • the drive sub-unit and the driven sub-unit may have a geometrical shape and mass which are respectively selected such that the driven sub-unit partially or fully compensates a rotation of the drive sub-unit that is caused by a pulse of angular momentum or torque.
  • an electric actuator which comprises a rotatably mounted drive sub-unit and a rotatably mounted driven sub-unit.
  • the driven sub-unit may comprise or may be coupled to a spindle of a spindle drive.
  • the drive sub-unit and the driven sub-unit may have rotation axes which extend parallel to each other, but which are offset from each other.
  • a first moment of inertia of the drive sub-unit and a second moment of inertia of the driven sub-unit may be matched to each other.
  • Matching the first and second moments of inertia may be done in such a way that the driven sub-unit substantially compensates a rotation of (or a torque on) the drive sub-unit that is generated by an angular momentum or torque pulse on the housing.
  • An actuator for an electric lock comprises a stator of an electric motor.
  • the actuator comprises a drive sub-unit which is rotatably mounted.
  • the drive sub-unit comprises a rotor of the electric motor, a drive shaft fixed to the rotor in a torque-proof manner or integral with the rotor, and a drive wheel fixed to the drive shaft in a torque-proof manner.
  • the actuator comprises a driven sub-unit which is rotatably mounted.
  • the driven sub-unit comprises a driven shaft extending parallel to the drive shaft and a driven wheel fixed to the driven shaft in a torque-proof manner. The driven wheel is engaged with the drive wheel.
  • the drive sub-unit has a first moment of inertia, I 1
  • the driven sub-unit has a second moment of inertia, I 2 , wherein
  • the first and second moments of inertia may be matched such that
  • the first and second moments of inertia may be substantially equal to each other.
  • matching the first moment of inertia and the second moment of inertia to each other has the effect that manipulatory torque or angular momentum pulses applied onto a housing or bracket to which the actuator is mounted do not result in a significant undesired rotation of the driven shaft, because the first and second moments of inertia cause torques of identical magnitude but opposite directions to act on the drive sub-unit and the drive sub-unit.
  • the meshing engagement of the drive wheel and the driven wheel causes the net torque to be small or even substantially zero, preventing or substantially reducing an undesired rotation of the driven shaft in response to manipulatory actions that involve the application of a series of torque pulses.
  • the drive sub-unit may have a first rotation axis
  • the driven sub-unit may have a second rotation axis which is parallel to the first rotation axis, but offset from the first rotation axis in a direction transverse to the first rotation axis.

  • Such a configuration of the coil spring further increases safety against mechanical manipulation, such as against the application of force pulses in a direction parallel to the first rotation axis of the drive sub-unit.
  • the spindle drive may comprise a projection projecting from the control member and engaged with the coil spring.
  • the projection may be a finger projecting from the control member in a direction transverse, in particular perpendicular, to a center axis of the coil spring.
  • the finger may have a longitudinal axis in the direction transverse to the center axis of the coil spring.
  • a length of the finger along its longitudinal axis may be greater than a width and height of the finger in the directions transverse to its longitudinal axis.
  • the actuator may further comprise a guide arrangement for guiding linear displacement of the control member.
  • the guide arrangement may secure the control member against pivoting.
  • the guide arrangement may comprise at least one guide rail.
  • the actuator may further comprise a coupling mechanism adapted to selectively couple a manually operable actuation element with a locking element when the coupling mechanism is in an engaged state.

  • the actuator may further comprise a bias mechanism coupled to the control member to bias the control member to the second position.
  • the bias mechanism may provide enhanced safety against mechanical manipulation attempts. For illustration, when there is a small mismatch between the first and second moments of inertia due to manufacturing tolerances, the bias mechanism ensures that the control element will be moved towards a position in which the lock is safe when torque pulses are applied in an attempt of fraudulent tampering.
  • the bias mechanism may comprise a bias spring.
