Definitions

  • the present invention relates to a motor vehicle door lock according to the The preamble of claim 1 and the use of a diode in one Motor vehicle door lock.
  • Under motor vehicle door lock there is generally a side door lock, a rear door lock, a tailgate lock, a hood lock or the like of a motor vehicle to understand.
  • a motor vehicle door lock which has an electric motor for driving an actuator.
  • the electric motor is only in one Drive direction of rotation operable.
  • the polarity of the DC drive voltage will not be changed.
  • the motor vehicle door lock also does not have one completely self-locking gearbox in the form of an electric motor rotatable worm on the control element designed as a worm wheel works.
  • the control element is provided with a driver pin, which is on a Pawl of the motor vehicle door lock for pivoting the same can act.
  • the pawl has a stop against which the Driver pin of the actuator in a pivoted position of the pawl runs so that the further rotary movement of the control element and thus also the Electric motor in the direction of rotation - temporarily, as long as the pawl is in this swivel position - be blocked.
  • the present invention has for its object a motor vehicle door lock and use of a diode in a motor vehicle door lock specify so that on simple, inexpensive and less prone to Way an unwanted moving back one of an electric motor driven actuator can be minimized.
  • a basic idea of the present invention is a diode to be connected in parallel to the electric motor when the electric motor is switched off minimizing a turning back in that when turning the electric motor back occurring voltages through the diode quasi short-circuited or be degraded at least very strongly, which results in a very strong braking of the electric motor results. As a result, it becomes an undesirable one Return movement of one with the electric motor directly or in particular minimized indirectly via a gear connected actuator.
  • a particular advantage of the proposed solution is that none Mechanism to block the return movement is required.
  • a diode is available at a very reasonable price. Accordingly, there is a simple, affordable solution.
  • Another advantage is that a diode is not subject to wear. As a result, the result is significantly reduced compared to the prior art Susceptibility or probability of failure. This is particularly true in With regard to the required longevity in automotive components significant advantage.
  • the diode can also be used for interference suppression because of voltage spikes dismantled via the diode when switching off the electric motor can be. Accordingly, through the proposed use the diode is an otherwise usually required electronic Components to suppress the motor are eliminated.
  • the single figure shows a schematic representation of a proposed one Motor vehicle door lock 1 with an electric motor drive 2.
  • the drive 2 has a drive that can only be operated in a drive direction of rotation 3, schematically indicated electric motor 4, the as a DC motor is formed and by a control device 5 with an adapted DC drive voltage U can be applied if necessary.
  • the Control device 5 can thus switch the electric motor 4 on and off, such as schematically indicated by switch 6.
  • the electric motor 4 is connected to a gear 7, which in the example shown is formed by a worm with a worm gear trained actuator 8 meshes, so that a rotation of the electric motor 4 in the drive direction of rotation 3 a turning of the adjusting element 8 according to arrow 9 causes.
  • the transmission 7 is at least not completely self-locking here trained, at least as far as a turning back of the control element 8 against Direction of rotation 9 is affected.
  • the actuating element 8 carries a protruding in the axial direction pin-like functional element 10, which on a closing element of the Motor vehicle door lock 1, here a pawl 11 can act. Accordingly, the functional element 10 as an actuator in the Understand the present invention.
  • the single figure shows the motor vehicle door lock 1 in a functional position, in which a stop 12 of the pawl 11 further movement of the Control element 8 or the functional element 10 in the direction of movement 9 blocked because the stop 12 in the path of movement of the functional element 10 is located.
  • the Pawl 11 a main detent 13 of an associated lock latch 14 free in turn with an indicated, in particular bolt-shaped locking block 15 cooperates.
  • the actuating element 8 or the functional element 10 can pivot cause the pawl 11 in the functional position shown, here the functional element 10 acts on a control edge 16 of the pawl 11 and finally in the functional position shown by striking on Stop 12 is blocked in its movement according to arrow 9.
  • the electric motor 4 is forcibly braked and mostly only then is the electric motor 4 switched off. In others The electric motor 4 is already executed a little before the blocking switched off, so that the wake caused by moments of inertia of the Drive 2 a run-up of the functional element 10 to the stop 12 Consequence.
  • the control device 5 detects, for example the current increase associated with the blocking and then switches the electric motor 4. This has the advantage that no position sensor or the like. is required.
  • the device is switched off beforehand Control device 5 usually depending on the position of the control element 8 or of the functional element 10 signal, see that, for example, a position sensor or the like is required.
  • a diode 17 is parallel to the electric motor 4 switched.
  • This diode 17 or a corresponding, comparable electrical Component having properties has a reverse voltage that Above the DC supply voltage U that can be applied to the electric motor 4 lies.
  • the diode 17 is oriented or switched such that when switched on Electric motor 4 - ie applied drive voltage U or closed Switch 6 - the drive DC voltage U is not via the diode 17 is short-circuited, but is applied to the electric motor 4.
  • the diode 17 causes rotation of the electric motor 4 against the direction of rotation 3 (turning back) is minimized.
  • the turning back of the electric motor 4 can in particular in the blocking position due to the partly inevitable and partly desired elasticities of the drive train starting from the electric motor 4 via the gear 7, the control element 8 and the functional element 10 up to the stop 12 or the pawl 11 when the Actuating element 8 or the functional element 10 caused by the stop 12 become.
  • the diode 17 causes the electric motor to turn back 4 that the turning back is minimized by a kind of short-circuit braking is because when turning back the electric motor 4 one to the polarity of the DC drive voltage U with opposite polarity is generated, the via the diode 17 - the switched for these voltages in the forward direction is - dismantled or quasi short-circuited. This leads to a sufficiently strong minimization of the turning back of the electric motor 4, so that mechanical blocking of the control element 8 or the functional element 10 or another part of the drive train or the drive 2 is not required.
  • Another advantage of the diode 17 is that it also suppresses interference of the electric motor 4 is used because when the electric motor 4 is switched off occurring voltage peaks can be reduced via the diode 17. Accordingly, an otherwise usually required electronic Component for interference suppression of the electric motor 4 are omitted.
  • the diode 17 is part of the control device 5 shown and especially integrated into this. However, this is not mandatory required.
  • the diode 17 can also be directly on Electric motor 4 arranged or - for example, retrospectively with existing ones Constructions - between the control device 5 and the Electric motor 4 may be arranged.
  • the pawl 11 is due to the swiveling Lock latch 14, namely its trailing arm, which carries the latching, further pivotable clockwise so that the stop 12 completely from the movement path of the actuating element 8 or of the functional element 10 can be moved out and the control element 8 or the functional element 10 Turning on the electric motor 4 continues its movement along its rotating Movement path - here in direction of rotation 9 - can continue.
  • control element 8 with its functional element 10 also other rotary positions at a standstill with the electric motor switched off Take 4 if necessary and also with other levers, elements and other parts of the locking mechanism of the motor vehicle door lock 1 interact can.
  • the drive 2 acts on the pawl 11 of the Motor vehicle door lock 1, so that the motor vehicle door lock 1 by an electric motor can be opened. So this is a so-called Electric lock. However, this is not absolutely necessary.
  • drive 2 generally with any part of the locking mechanism of the motor vehicle door lock 1 interact, for example with a locking lever, not shown, and only a central locking function serve.
