Definitions

  • the invention relates to a motor vehicle door lock, with a locking mechanism, at least one actuating lever for the locking mechanism and a motor drive for opening the locking mechanism.
  • the locking mechanism mainly consists of a rotary latch and a pawl.
  • Such motor vehicle door locks are well known and are used when such a lock is to be opened electrically. Because the motor drive regularly includes an electric motor. The electrical opening described is initiated by a so-called “keyless entry” or “keyless go” operation by way of example, but not by way of limitation. In this case, an upstream wireless authorization query is carried out by an operator willing to access, which, after a positive check, acts on the motor drive to open the lock so that an associated motor vehicle door can then be opened and / or opened immediately thereafter. This may be done by motor or manually.
  • the motor drive in question merely opens the associated locking mechanism. This means that this is previously transferred to the unlocked state if it is not present.
  • the motor drive can also be used to first unlock the motor vehicle door lock and then to open the locking mechanism.
  • the invention is based on the technical problem of providing a functional, simple and inexpensive solution for a motor vehicle door lock of the generic type for motorized opening.
  • a generic motor vehicle door lock is characterized according to the invention in that the motor drive acts directly on the locking mechanism and in particular the pawl via the actuating lever.
  • the motor drive can be designed to be reversing and preferably has an output disk with a cam on the front and a rotation angle limiting element on the rear.
  • the rotation angle limiting element interacts with a fixed stop.
  • This fixed stop may be fixed on the lock case, lock housing, etc.
  • the stop ensures that rotary movements of the motor drive and consequently of the driven disk are limited in the direction of actuation and reversing.
  • the stop actually provides two stop surfaces, on the one hand for the rotation angle limiting element moving in the actuation direction and on the other hand for the case that the rotation angle limiting element is moved in the reversing direction.
  • the operating lever is largely two-armed with an operating arm and a trigger arm.
  • the actuator arm is largely acted upon by the drive, while the trigger arm on the locking mechanism and here in particular the
  • the actuating lever may additionally have a third arm, the opening arm, on which a mechanical opening device can engage.
  • This third arm of the actuating lever thus ensures that, for example, the locking mechanism can still be opened mechanically if the motor drive fails. It is conceivable here that a locking cylinder works with a cam on this third arm.
  • the procedure is usually such that the motor drive drives the driven pulley in of the actuating direction for opening the locking mechanism until the angle of rotation limiting element bears against the stop in an open position.
  • the stop has two stop surfaces, namely an actuating surface and a reversing surface. In the open position, the rotation angle limiting element rests on the actuating surface of the stop.
  • the opening position is maintained until the locking mechanism is securely opened. It is conceivable here to query this locking opening via a sensor, for example on the rotary latch, a rotary latch switch or the like. If the fully opened rotary latch triggers the relevant rotary latch switch, a control unit recognizes that the locking mechanism is open and the open position can be released (again). While the motor drive acts on the driven pulley or the actuating lever in its actuating direction to open the locking mechanism and also in the open position, the actuating lever as a whole ensures that the pawl is lifted off the rotary latch so that the rotary latch can open with spring support. The control unit only sends a command to the motor drive for reversing when the locking mechanism has been opened securely.
  • the motor drive acts on the actuating lever in its reservation direction until the pawl previously held by the actuating lever is released. Since the rotary latch is open in this situation, the free pawl comes on the catch and can easily fall into the catch in a subsequent (manual) closing operation of the motor vehicle door if this is brought into the closed position by a locking bolt during this operation.
  • the previously mentioned opening position of the actuating lever and consequently also of the driven disk can be set and maintained without great effort on the part of the motor drive.
  • the actuating lever has a spring against which the motor drive must work when the locking mechanism is opened.
  • the counterforce built up by this spring now runs radially in the direction of an axis of rotation of the driven pulley, preferably through the cam.
  • the motor drive can even be switched off in the open position in strictness or its self-locking forces are sufficient because the cam is only acted on radially in the direction of the axis of rotation of the driven disk by the counterforce of the spring and does not experience any lateral forces. Because these side forces are missing, the spring on the operating lever does not turn the cam in either direction in the open position. In any case, rotations in the actuation direction are blocked because the rotation angle limiting element rests on the actuation surface of the stop.
  • Fig. 5 is a schematic functional flow diagram over time.
  • a motor vehicle door lock which, as usual, has a locking mechanism 1, 2 consisting of a rotary latch 1 and pawl 2.
  • a motor drive 4, 5, 6, 7 for opening the locking mechanism 1, 2 can be seen.
  • the motor drive 4, 5, 6, 7 consists of an electric motor 6, an output disk 5, a cam or actuating cam 4 arranged on the output disk 5 and a rotation angle limiting element 7 together.
  • the electric motor 6 is able to move the driven disk 5 clockwise and counter to this, so it works - like the entire motor drive 4, 5, 6, 7 - in a reversing manner. This is expressed by a double arrow in Fig. 1.
  • the motor drive 4, 5, 6, 7 only acts directly on the locking mechanism 1, 2 via the actuating lever 3.
  • the actuating lever 3 has a total of three arms and has an actuating arm 3a, a trigger arm 3b and finally an opening arm 3c.
  • the opening arm 3c makes it possible
  • the actuating arm 3a which is actuated by the drive 4, 5, 6, 7, is more important for the motor opening that is essential to the invention, more precisely by the cam 4.
  • the trigger arm 3b which acts on the locking mechanism 1, 2, more precisely the pawl 2, is working.
  • the driven disk 5 is equipped with the rotation angle limiting element 7 on its rear side.
  • This rotation angle limiting element 7 works together with a fixed stop 8, which may be fastened in the lock housing 13.
  • the stationary stop 8 has two stop surfaces 8a, 8b, namely an actuating surface 8b and a reversing surface 8a.
  • control unit 12 forwards corresponding commands to the electric motor 6 for its actuation.
  • a sensor surface 11 reaches the sensor or switch 10, so that the latter transmits a first signal to the control unit 12, as is shown by the rising edge in the lower part of FIG. 5. This is followed by a contact of the cam 4 with the actuating arm 3a of the actuating lever 3.
  • the motor drive 4, 5, 6, 7 acts on the actuating lever 3 in its actuating direction to open the locking mechanism 1, 2 (clockwise movement of the driven disk 5 in the front view in FIG. 1) until the angle of rotation limiting element 7 rests on the stop 8 , more precisely on its actuating surface 8b.
  • This state becomes clear during the transition from FIG. 1 to FIG. 2 and further to FIG. 3.
  • the sensor Care surface 11 ensured that the sensor or switch 10 has received a switch-off pulse corresponding to a second signal. Along with this, the falling edge of the first rectangular pulse was reached in the lower illustration in FIG. 5.
  • the control unit 12 Due to the safe opening of the locking mechanism 1, 2, the control unit 12 now ensures that the motor drive 4, 5, 6, 7 is acted upon in the reversing direction.
  • the reversing direction corresponds to the fact that the cam 4 and thus the driven pulley 5 carrying it perform a counterclockwise movement in the front view.
  • the cam 4 moves away from the actuating arm 3a of the actuating lever 3.
  • the motor drive 4, 5, 6, 7 is acted upon in the reversing direction until the pawl 2 previously held by the actuating lever 3 is released.
  • the sensor or switch 10 registers a switch-on process again. call through the sensor surface 11 sliding past it. This process corresponds to the rising flank of the second rectangular pulse in the lower illustration according to FIG. 5.
  • the rotation angle limiting element 7 reaches the reversing surface 8a of the stop 8 shown.
  • the sensor surface 11 previously generated a switch-off pulse at the switch 10, which corresponds to the falling edge of the second square-wave pulse.
  • the actuating lever 3 performs the movement shown in the upper illustration of FIG. 5 in the process described, individual selected points and positions being indicated.
  • the counterforce built up by the spring F on the actuating lever 3 runs radially in the direction of the axis 5 ′ of the driven pulley 5. This is indicated by an arrow in the relevant FIG. 3.
  • the opposing force also runs through the cam 4. In this way, the opening position according to FIG. 3 can be represented with particularly little force because lateral forces are eliminated which could turn the driven pulley 5 in one direction or the other.
  • the sensor 10 first sensed the falling edge through the sensor surface 11 running past and, moreover, the microswitch or rotary latch switch 9 registered that the rotary latch 1 is open.
  • the electric motor 6 now continues to run until the driven pulley 5 comes to rest with its angle of rotation limiting element 7 against the actuating surface 8b of the stop 8. This happens at time 5.
  • the blocking position of the electric motor 6 can be evaluated and serves as a signal to operate the electric motor 6 reversing. This happens from time 5 to time 6, the electric motor 6 running up in this direction in the reversing direction. After the end of the sensor surface 11 has passed the sensor or switch 10 and the second rising edge has been registered by the sensor 10, the release of the pawl 2 begins at time 6. This release of the pawl 2 continues until time 7 , After registration of the falling edge by the sensor 10, the electric motor 6 continues to run unchanged, and that is until the angle of rotation limiting element 7 reaches the reversing surface 8a of the stop 8 in the position 8. In this case too, the blocking process can be evaluated in order to (again) reverse the direction of movement of the electric motor 6.
