Definitions
- the invention relates to a motor vehicle door lock, with a locking mechanism, furthermore with at least one release lever, and with a drive acting on the release lever.
- the drive is usually an output disk that is equipped with a rotating output control cam or a control cam.
- This driven pulley is rotated for the most part with the help of an electric motor, which is initiated and monitored by an electronic control device.
- the driven disk works with an associated driven control curve on a lever arm of the release lever for the pawl.
- the other lever arm of the release lever is loaded by a quick release spring.
- the design is such that the release lever in question can be moved into the lifting position for the pawl under the influence of the quick release spring and takes the pawl accordingly when the output control curve makes a rotary movement.
- a generic motor vehicle door lock is characterized in that the drive acts indirectly on the release lever via an intermediate energy storage device.
- this energy storage device is a spring. This spring or energy storage device couples two mutually movable components of the drive to one another.
- the movable components of the drive are two disks that are regularly arranged coplanar to one another, namely an output disk and an adjusting disk, which rotate about a common axis.
- the drive usually has a motor with an output shaft and worm wheel, which acts on the output disk.
- the release lever actuated by the drive is only moved when this tensioning is finished and the driven disk and the adjusting disk have passed the predetermined dimension or an associated adjustment path to one another. As a result, the pawl, which is actuated by the release lever, is lifted.
- the release lever After this release process has been completed, the release lever returns to its original position. At the same time, the adjusting disk is released from the release lever and, under the influence of the spring that now relaxes, turns back to its starting position in comparison to the driven disk.
- the driven pulley itself can be moved into the starting position with the aid of the drive, so that in the end both movable components or pulleys return to their original position.
- the spring may be a spiral spring, one leg end of which is connected to one movable component and the other leg end of which is connected to the other movable component.
- the adjusting disc has a control cam on the front, which rather works on the release lever. This control cam ensures that the release lever is only acted on during a certain adjustment path of the adjusting disk and can return to its starting position (spring-assisted) after passing the control cam.
- the adjusting disk is largely equipped with a recess in which a pin on the driven disk dips. This pin sweeps over the recess when the spring or energy storage device is tensioned.
- the recess in the adjusting disk preferably has stops at each end, which limit the movement of the pin on the drive disk.
- the adjusting disc is also equipped with a pin.
- the spring or spiral spring is tensioned between the two pins that thereby converge.
- the previously tensioned spring pushes the two pins apart again, so that the driven pulley and adjusting pulley assume their original position (again).
- a motor vehicle door lock is made available which, when opened electrically, always ensures that the opening or unlocking process initiated once by the drive is in any case carried through to the end. This means that the motor vehicle door lock is always moved into a position in which the locking mechanism is already open or - more often - is unlocked and can be opened by an additional independent opening stroke.
- the invention essentially achieves this by the fact that the drive acts indirectly on the release lever via the interposed energy storage device.
- the drive ensures that when the release lever is at the same time fixed, the energy storage device or spring is tensioned first, and only then does the release lever move or act upon it with the aid of the drive, taking into account the tensioned energy storage device experiences.
- the release lever After the release lever has actuated the pawl and moved the locking mechanism to the desired position, it (the release lever) is moved back to its starting position with spring support.
- the control cam of the adjusting disk is released from the release lever so that the energy storage device or spring can relax and the two components or the adjusting disk and the driven disk assume their starting position (possibly after additional rotation by means of the drive).
- the energy storage device stores part of the drive energy, which is used, if necessary, to move the drive or the adjusting disk in order to be able to act on the release lever, even if the motor has failed or is blocked. This is where the main advantages can be seen.
- FIG. 1 shows the motor vehicle door lock according to the invention, reduced to the essential components in the rest position or main rest position of the rotary latch;
- FIG. 3 shows the object according to FIG. 2 in a functional position with the trigger lever and Fig. 4 shows the release lever moved back to the starting position with the energy storage device relaxing.
- a motor vehicle door lock which is equipped with a locking mechanism 1, 2 consisting of a rotary latch 1 and a pawl 2.
- a release lever 3 to which an internal actuation lever at 4 may be connected.
- the trigger lever 3 is acted upon by a drive 5, 6, 7, 8, 9.
- the drive 5, 6, 7, 8, 9 includes an electric motor 5, to which an output shaft with a worm wheel ⁇ is connected. With this worm wheel 6 meshes an output disk 7, which together with an adjusting disk 8 forms two mutually movable components 7, 8 of the drive 5, 6, 7, 8, 9. Both disks 7, 8 are arranged coplanar to one another and rotate about a common axis 10.
- the adjusting disk 8 is located above the driven disk 7.
- a control cam 9 is attached to the adjusting disk 8 and acts on the release lever 3 with a control cam 11.
- the two disks 7, 8 are connected to one another via an interposed energy storage device 12.
- This energy storage device 12 is a spring or spiral spring 12, so that the drive 5, 6, 7, 8, 9 acts indirectly on the release lever 3 via this spring 12 and not directly on the release lever 3 Release lever 3 adjusted, as is followed in the prior art.
- One leg end 12a of the spiral spring 12 abuts a raised pin 13 of the adjusting disk 8.
- the other leg end 12b is supported on a further pin 14 which stands on the driven pulley 7. Consequently, the spring 12 is connected with its one spring end 12a to the adjusting disk 8, while the other spring end 12b is connected to the driven disk 7, as it were.
- a switch 15 can also be seen, which is arranged below the driven disk 7. With the help of this switch 15, the position of the driven pulley 7 can be queried and transferred to a control device, not shown, which in turn controls the electric motor 5 accordingly.
- a spring 16 finally ensures that the trigger lever 3 pivots in a clockwise direction as soon as it is deflected as soon as it is no longer deflected with the help of the control cam 9. The release lever 3 thus returns spring-assisted to the starting position according to FIG. 1 when the cam is removed. The way it works is as follows. Starting from FIG.
- an electrical opening or unlocking of the motor vehicle door lock shown is initiated, for example, by an operator willing to access actuating an outer door handle.
- a switch provided here then starts the electric motor 5 with the aid of the control device (not shown).
- this starting process can also take place in connection with a "keyless entry” access, and is triggered by a remote query between an identification means of the operator and the associated one motor vehicle.
- the electric motor 5 is acted upon by the control device in the sense that the driven pulley 7 moves counterclockwise (cf. the transition from FIG. 1 to FIG. 2).
- This predetermined dimension M or the associated adjustment path is established in that the pin 14 of the output Disk 7 can only be moved within an associated recess 17 in the adjusting disk 8 with end stops 18 ', 18''. That is to say, when the control cam 9 is in contact with the cam arm 3a, a further counterclockwise rotation of the driven pulley 7 leads to the fact that its pin 14 is moved away from the first stop 18 'and is moved towards the second stop 18''.
- the pin 13 can move away from the pin 14 by the force of the spring 12.
- the spring 12 relaxes, so that the stop 18 'moves against the pin 14 and the driven disk 7 together with the adjusting disk 8 can be moved back by the electric motor 5 into the starting position according to FIG. 1, which is in principle also possible by spring force ,
- the driven pulley 7, the adjusting pulley 8 and the control cam 9 perform a total of approximately half a turn in the counterclockwise direction, specifically free of the release lever 3.
