Definitions

  • the invention relates to a lock for a movable arrangement such as a door, tailgate or the like of a vehicle, according to the preamble of claim 1.
  • a lock with lock components such as a rotary latch and pawl is known, in which the pawl locks or releases the rotary latch.
  • the release takes place depending on the specifications of an operator, possibly via a remote control, by actuating an actuator which moves the pawl, which then releases the rotary latch, so that the movable arrangement (such as door, tailgate or the like) opens or can be opened.
  • This lock works in and of itself satisfactorily, but has the disadvantage that for safety reasons additional devices are required by means of which a mechanical connection between a handle and the component of the lock is given or can be produced in an emergency.
  • This known lock is a multitude of Bowden cables which, in an emergency, transmit actuation of the handle to the actuator or the pawl via a lifting mechanism.
  • a large number of additional components are required, which require a disproportionate amount of assembly work, since the handle is generally arranged away from the lock. Therefore, the Bowden cables must be in the body in particular the door, which not only leads to a high assembly effort, but also to high material costs.
  • the invention is therefore based on the object of providing a lock which fulfills the necessary safety precautions from a comfort point of view such that an opening of the movable arrangement is still provided if an actuator fails.
  • direct drive means that whenever the first actuator is turned on, the other actuator is also turned on at the same time, so that if one actuator fails, another actuator is still available for opening the movable arrangement.
  • direct drive means that the movement of the actuator is transmitted to the component without under or translation or without changing the transmission movement. This is the case, for example, in the case of an actuator designed as an electromagnet with an actuating element, in which the linear movement of the actuating element is transmitted directly to the pawl.
  • An indirect drive is to be understood that in the normal case in the sense of an opening process, the first actuator is always activated and only in the event of a defect in the first actuator, the further actuator can be activated - possibly with a time delay.
  • Under indirect Drive is also to be understood that the movement of an actuator or both actuators is implemented (for example from a linear movement into a rotary movement or vice versa), reduced or translated. This increases the design freedom when designing the lock depending on the actuator used.
  • FIG. 1 shows a section of a lock, in which components such as remote control, handling with detection devices for detecting the actuation of the handles and other elements of the lock are not shown.
  • a pawl drive provided with the reference number 1 in FIG. 1 has a rotary latch 2 which, in a manner known per se, engages around a locking bolt 3, as a result of which the movable arrangement is held in its closed state.
  • the rotary latch 2 is locked in the position shown by a pawl 4, the pawl 4 being movable about a pivot point 5. If the pawl 4 is partially rotated clockwise around the pivot point 5 when viewing FIG. 1, the catch 2 is released so that the movable arrangement can be opened.
  • the rotary latch 2 and the pawl 4 are each biased with a rotary latch spring 6 and a pawl spring 7 in the position shown in FIG. 1.
  • the gear segment 8 After switching on the actuator 10, the gear segment 8 is rotated clockwise, whereby the pawl 4 is taken along and thereby the catch 2 is released. After the actuator 10 has been switched off, at least the gear segment 8 returns to its initial position, for example by spring loading or by reversing the direction of rotation of the actuator 10, which is defined by a stop 12.
  • a further actuator 13 is provided, which is also designed as an electric motor, which carries a further pinion 14 on its drive shaft.
  • the two actuators 10 and 13 are constructed as identical electric motors, which are inexpensive and reduce the number of parts.
  • the pinion 14 meshes with a further gearwheel segment 15, the gearwheel segment 15 carrying a gearwheel 16 of smaller diameter, this gearwheel 16 meshing with the gearwheel segment 8.
  • a gear is arranged both between the first actuator 10 and the pawl 4 and between the further actuator 13 and the pawl 4, the two gears being freewheeling against each other.
  • the two gears designed as a reduction gear are designed so that the gear between the other Actuator 13 and the pawl 4 has a higher reduction than the gear between the first actuator 10 and the pawl 4.
  • the actuator 10 generates a small torque (for example between 1 to 5 Nm) with which the pawl 4th can be moved from its locked position to the release position in a short time (for example in the time range between 10 and 500 ms).
  • the further reduction gear is designed so that the actuator 13 generates a high moment (for example in the range from 10 to 50 Nm) for a longer period of time (for example between 1 and 5 seconds).
  • the first actuator 10 is activated, the pawl 4 releases the rotary latch 2, which is detected by means of the rotary latch switch 17.
  • the actuator 13 deactivated, that is, that it is not controlled. If the rotary latch switch 17 is not actuated within a predeterminable period of time or after a predeterminable period of time has elapsed, which means that the door cannot be opened by means of the actuator 10, the actuator 13 is actuated instead of the actuator 10, so that the electromechanical one opens by means of the latter the movable assembly is initiated.
  • the further actuator 13 can be switched on immediately or after a delay after detection of an accident (for example when a trigger signal for an airbag is present).
  • an emergency power supply can be provided at least for the actuator 13, ideally for both actuators 10 and 13.
