Definitions

  • the invention relates to a motorized actuating element for a central locking system, which has a lock rod provided for actuating a door lock, coupled with a button rod and movable between two end positions by means of a motor, and a locking device for theft protection.
  • a motorized actuating element for a central locking system which has a lock rod provided for actuating a door lock, coupled with a button rod and movable between two end positions by means of a motor, and a locking device for theft protection.
  • Such actuators are installed in central locking systems of today's motor vehicles and are generally known.
  • the button bar is firmly connected to the lock bar.
  • the lock bar and thus also the button bar is blocked so that a burglar cannot pull up the security buttons at the ends of the button bars in the interior after a violent opening of a window and then open the doors.
  • the anti-theft device can only be removed with the key by actuating an electrical contact in the lock and thereby releasing the lock by an electric motor.
  • a disadvantage of the known central locking systems is that the anti-theft device can no longer be unlocked if the vehicle electrical system fails. For this reason, the driver's door is not equipped with such an anti-theft device and instead there is a mechanical anti-theft device that can be operated using the key. As a result, at least the driver's door can still be opened in the event of a failure of the vehicle electrical system.
  • a disadvantage of such a central locking system is, of course, that the anti-theft protection of all doors can only be carried out by means of the key on the driver's door.
  • the invention has for its object to design a motorized actuator of the type mentioned in such a way that even without energy supply via the vehicle electrical system, all door locks can be opened if they are in their anti-theft position beforehand and which have a lock cylinder in the presence of vehicle voltage Doors can be operated.
  • the anti-theft device is formed by a lock blocking the button bar and the button bar is releasably coupled to the lock bar by means of a locking device by force.
  • the button bar remains in its securing position, however, the lock bar can move relative to the button bar, since the latching device disengages. In this way, it can be prevented with simple means that a vehicle can no longer be opened, for example if the vehicle is accidentally left on Lamps the battery has been drained.
  • the actuating element according to the invention is of course not only suitable for door locks, but in particular also for a trunk lock.
  • the actuating element is of particularly simple construction if, according to an advantageous embodiment of the invention, the lock is formed by a pawl on a lever end of a pivotably mounted two-armed locking lever, the other lever arm of which in unlocked state in the movement path of the spindle nut moving into the position of the anti-theft device.
  • the locking lever When the spindle nut is retracted, the locking lever easily returns to the unlocking position when it is biased by a spring in the unlocked position.
  • the releasable locking connection between the lock rod and the button rod is particularly simple if a coupling piece with a locking recess is provided on the lock rod, whereas the knob rod has a counterpart with a blind hole in which a ball engages against a coupling state in the locking recess adjacent compression spring is provided.
  • the lock bar When the button bar is pulled up, the lock bar is reliably carried along, even if greater forces have to be overcome as a result of friction if, according to another embodiment of the invention, the counterpart engages with a projection under the lock bar.
  • a further, very particularly advantageous embodiment of the invention consists in that, in order to limit the downward stroke of the spindle nut when the closed position is reached, a limit switch which can be actuated by the spindle nut and is switched in such a way that it can be energized for a short time to reach the anti-theft position is provided.
  • This limit switch makes it possible to reach the anti-theft position with the same electric motor as the two other positions. No separate drive is required to operate the anti-theft device.
  • buttons 1 and 2 By pulling up a single button bar, the other button bars can also be moved into their unlocked position if a switch which can be actuated by the lock bar immediately before reaching the open position is provided in the housing.
  • the actuating element according to the invention can also be pneumatically driven instead of an electric motor drive.
  • Such an embodiment is structurally particularly simple if the lock is formed by a bolt that can be moved by means of an additional pneumatic servomotor.
  • the additional servomotor only needs to be briefly pressurized or depressurized in order to move the bolt into the desired end position if the pneumatic servomotor is a bistable servomotor. In such an actuator, the bolt remains in its end position by itself.
  • the latching device is particularly simple if, in accordance with another embodiment of the invention, a coupling piece is provided on the lock bar, which engages around the button bar and which has a pressure spring which acts on a ball in a radial bore relative to the button bar and which engages in a spherical cap-shaped recess of the button bar takes hold.
  • the actuating element shown in FIG. 1 has an electric motor 2 in a housing 1, which can drive a threaded spindle 4 in two different directions of rotation via a gear 3.
  • a spindle nut 5 is arranged, which can raise or lower a lock rod 6.
  • this lock rod 6 can also be moved by means of a key in the lock cylinder.
  • This ball 9 is held by a compression spring 10 in the locking recess 8.
  • This compression spring 10 is supported on the one hand on the ball 9, on the other hand on the bottom of a blind hole 11 of a counterpart 12, which forms a unit with a button rod 13 and is normally located exactly opposite the coupling piece 7. It engages with a protrusion 20 under the coupling piece 7.
  • the button rod 13 serves, as is common in motor vehicles, to lock the respective door after being depressed.
  • a cam 14 is provided, via which a pawl 15 of a locking lever 16 engages in the position shown in FIG.
  • This locking lever 16 is a two-armed lever which is arranged in the housing 1 so as to be pivotable about an axis 17 and is biased in the unlocking position by a spring 18. In the position shown, this locking lever 16 rests with the end of its lever arm which does not have the pawl 15 against the spindle nut 5, so that it cannot move out of the locking position. If the spindle nut 5 is moved upwards, the locking lever can pivot clockwise until its lower end, as seen in the drawing, reaches below the movement path of the spindle nut 5. That has to As a result, the locking lever 16 automatically pivots back into the locking position when the spindle nut 5 moves downward from the open or closed position into the anti-theft position.
  • FIG. 1 furthermore shows in the upper part of the housing 1 an electrical switch 19 which can be actuated by the coupling piece 7 shortly before reaching its upper end position, ie the open position of the door lock.
  • the button rod 13 In the anti-theft position of the components shown in FIG. 1, the button rod 13 cannot be pulled up and thus unlock the lock, since the pawl 15 holds the counterpart 12 in place. In the event of a power failure, however, the key can only be opened mechanically by moving the lock rod by mechanical means. Here, the ball 9 disengages from the locking recess 8, so that the coupling piece 7 is released from the counterpart 12 and a displacement of the lock rod 6 is possible independently of the button rod 13.
  • a limit switch 21 which can also be actuated by the spindle nut 5 and switches off the electric motor 2 when the spindle nut 5 moves downwards when the closed position is reached. This position is shown in Figure 2.
  • the limit switch 21 must be energized briefly.
  • the electric motor 12 then runs again and moves the spindle nut 5 downwards until it reaches a stop 22 and the electric motor 2 thereby switches off.
  • the spindle nut 5 has pivoted the locking lever 16 counterclockwise again, so that it assumes the locking position shown in FIG. 1 and holds the counterpart 12 in place.
  • FIGS. 3-5 shows that the inventive idea can also be applied to a pneumatic actuating element.
  • the button rod 13 has a radial bore 23 into which a bolt 24 can be moved by blocking the button rod 13 by pressurizing a pneumatic, bistable servomotor 25. Unlocking is carried out accordingly by applying a vacuum to the servomotor 25.
  • the lock rod 6 is moved between its end positions by means of a pneumatic membrane 26 of a bidirectional motor, which is not shown in any other way. It engages with a coupling piece 27 over the button rod 13 and is locked with it by means of a ball 28.
  • This locking connection is shown in more detail in FIG. 5.
  • the coupling piece 27 has a radial bore 29 with a compression spring 30 which presses the ball 28 into a recess 31 of the button rod 13.
  • Figure 4 shows the actuator in the closed position. In it it is possible to pull the button rod 13 upwards and thereby unlock the lock and also the other locks of the central locking system by actuating the switch 19. This allows you to open the doors using the inside door handles.
