Definitions

  • the invention relates to a locking device for a movable element, in particular for a door, a flap or the like, of a vehicle according to the features of the preamble of claim 1.
  • Such a locking device is known from DE 42 28 233 A1.
  • Lock elements such as pawl, rotary latch and one interacting with the rotary latch Locking bolt described.
  • the catch is from the pawl locks and encloses the locking bolt in the way that the door is locked.
  • a locking pin is provided to open the door, which opens an arm of the pawl acts.
  • the actuator is controlled by a Switch, which is dependent on the actuation of a handle, such as a Door handle is operated.
  • the actuator is an electromagnet with a extendable plunger shown, the plunger on one arm of the Pawl works. After energizing the actuator, the ram extends and moves the pawl so that it releases the catch to the Unlock the door. After this process or after When the actuator is de-energized, the tappet moves to its starting position back. It can happen that when moving from his Working position (actuation of the pawl) in its rest position dynamic rebounds at a stop in this rest position and thus the Pawl partially or entirely in the sense of a further release of the Rotary latch is actuated.
  • the invention is therefore based on the object of a locking device for a movable element, in particular for a door, a flap or the like, to provide a vehicle, the described false closings effectively prevented.
  • means are provided which control the actuator in such a way that that the actuator after activation from a rest position in a Working position for releasing the rotary latch controlled by the working position is returned to the rest position. Controlled by this Return from the working position to the rest position is guaranteed that the actuator, especially one acting within the actuator Actuator such as the plunger, or one of the actuator separate control element not in at rest position Can bounce back towards the working position, but in this rest position remains.
  • the control must be designed so that it bounces back is completely prevented or just bouncing back in one is permitted to such an extent that the actuation of the Pawl can lead to the release of the catch.
  • Such control can be done, for example, such that the movement of the actuator or its actuator from the Working position is recorded in the rest position and after driving one polarity reversal of the control variable to a braking effect to reach.
  • Another possibility is that the actuator for Actuation of the pawl controlled with a certain control variable is controlled and driven back with the reversed control variable becomes.
  • the actuator can be controlled with pulse width modulation.
  • a pulse width modulated control signal for the actuator there is advantageously a control signal that is the most diverse Circumstances can be adjusted.
  • the pulse width modulation is adaptable to different actuators so that it doesn't matter which what type of actuator (such as electromagnet, electric motor or the like) is used.
  • the control signal optimal be adapted to the existing conditions.
  • the pulse width when the actuator is activated from its rest position to the working position smaller than the pulse width when actuating the actuator to reach the rest position.
  • the pulse width when the actuator is activated changeable to reach the rest position. If you choose the pulse width such that first when moving out of the working position a position a quick movement is reached and shortly before reaching the rest position of the pulse width is reduced in an advantageous manner so that the effect is achieved that the actuator or its actuator is first quickly moved out of the area in which the pawl is arranged, by reducing the pulse width of the control signal is achieved that the actuator or its actuator is braked.
  • This changeability of the pulse width can be continuous or discontinuously over the area between the working position and the rest position.
  • the actuator is a control module, in particular a power amplifier, assigned to the actuator, that together with the actuator and possibly other parts of the locking device is arranged in a housing.
  • a control module in particular a power amplifier, assigned to the actuator, that together with the actuator and possibly other parts of the locking device is arranged in a housing.
  • the mentioned Locking device designed as a complete module and pre-assembled can be that later in the door, the flap or the like of the Vehicle is used. It is then, especially when using funds for detecting the actuation of a handle (e.g. door handle), depending whose actuator is controlled, only an electric one Wiring required.
  • the housing can Have plug or a socket or the like, through which the Locking device can be connected to the mentioned other elements got to.
  • a control module is assigned to the actuator, that is part of a central control device.
  • Figure 1 shows an example of a locking device for a door, in particular for a motor vehicle door, the invention not being based on this mechanism alone, but also applicable to similar or differently designed mechanisms is.
  • a rotatably mounted rotary latch 1 encloses with its two legs a striker 2, wherein the rotary latch 1 is biased by a rotary latch spring 3 is.
  • a pawl 4 cooperates is also spring-loaded, this in the embodiment according to FIG Spring is designed as a compression spring 5 and a lever arm of the pawl 4 presses in the direction of one leg of the rotary latch 1.
  • the reference number 6 is a direction of rotation of the rotary latch 1
  • the reference numeral 7 a direction of rotation the pawl 4 and with the reference numeral 8 a direction of movement of the closing wedge 2 attached to the unspecified door, wherein the direction of movement 8 represents an opening of the door.
  • the spring load of the Pawl 4 can also be realized by means of a tension spring.
  • the pawl is 4th via connecting elements (coupling rod 9 or Bowden cables) with a handle 10 connected, this handle 10 a sensor 11 for Actuation detection of the handle 10 is assigned and starting from a signal from the sensor, the means can be operated.
  • FIG. 1 there is also an opening direction 16 or one Closing direction 17 indicated so that after actuation of the actuator 10 this moves the pawl 4 in the opening direction 16, so that the pawl 4 releases the catch 1.
  • Figure 2 shows a control device 23 on which the sensors 11 for detection are connected to actuate the handle 10.
  • This corresponds to each a sensor 11 of a handle such as inside door handle or outside door handle.
  • a sensor 11 of a handle such as inside door handle or outside door handle.
  • Two sensors 11 each is assigned a control module 24 that the respective Actuator 10 controls, the actuator 10 in its two End positions can be locked or are self-locking and de-energized.
  • control device 23 is assigned an input device 25, via which the actuation requirements for the control device 23 are communicable. This can be done, for example, by means of manual input alternatively or as a supplement to this, take place remotely. So can for example, switching from the anti-theft position to the central locking position by means of a hand transmitter, whereas for An entry key is provided for setting the child lock position can be.
  • Reference number 26 denotes an output device, by means of, for example, a status display (for example child lock on / off) is possible.
  • the control device 23 operates as follows:
  • the control device 23 checks which actuation request via the Input device 25 was set. Depending on that, it will Control module 24, which is also in the control device 23 or in the actuator 10 can be integrated, controlled or not.
  • Figure 3 shows a signal sequence for controlling the actuator 10, wherein in the upper half of Figure 3 it is shown that the actuator 10 with a Square wave signal is driven with the amplitude U, the control takes place in such a way around the actuator 10 or its actuator from a rest position R, which is shown in Figure 1, in a working position Bring A.
  • the square wave signal shown is only an example of Clarification of how it works, with an actual execution Much more square pulses are required to control the actuator are.
  • the actuator 10 Shortly before reaching rest position R can also be provided, the actuator 10 with a short Pulse or with short pulses with the amplitude U or one to control smaller amplitude, the movement of the actuator 10 of would cause the rest position R in the working position A, so that the Energy of these short impulses reduces or destroys the kinetic energy.
