Definitions
- the invention relates to a motor vehicle lock, in particular a motor vehicle door lock, with a locking mechanism consisting essentially of a rotary latch and a pawl, and with an actuating lever chain with a coupling lever that works on the locking mechanism, wherein the coupling lever closes the actuating lever chain to act on the locking mechanism in the engaged state and opens it in the disengaged state, and wherein the coupling lever interacts with a positioning lever that controls it in order to change between at least two stable end positions in the sense of "engaged” and "disengaged”.
- the clutch lever has a control cam or link into which the clutch lever can engage with a pin.
- the actuating lever supporting the clutch lever can work on a release lever and, through the actuating lever chain closed in this way, lift the pawl from its engagement with the rotary latch in the closed position of the locking mechanism. In this way, the associated motor vehicle lock or its locking mechanism is opened.
- the clutch lever In addition to this engaged state of the clutch lever and the associated stable end position, it is also possible for the clutch lever to be pivoted relative to the actuating lever in such a way that the clutch lever cannot be brought into engagement with the release lever when the actuating lever is acted upon. In this case, the clutch lever assumes its disengaged state as further second stable end positions.
- the previously mentioned control cam or link is provided on a control lever in the prior art. In this way, the teaching described above makes it possible to simultaneously lock the operating lever and unlock the locking mechanism using an additionally provided electric motor drive unit. This has basically proven itself. This means that the electric motor drive or the relevant drive unit has a dual function.
- a comparable prior art which also describes a generic motor vehicle lock, is the subject of DE 10 2019 127 109 A1.
- a clutch lever is again implemented, which is guided using a link.
- the clutch lever has a pin that engages in the link.
- the backdrop is provided in or on an adjusting lever.
- the lever chain can be moved into a closing operating position using an emergency operating lever using an electric motor drive.
- the invention is based on the technical problem of further developing such a motor vehicle lock and in particular a motor vehicle door lock in such a way that functional reliability is increased and malfunctions are avoided.
- the invention proposes in a generic motor vehicle lock and in particular a motor vehicle door lock that the positioning lever engages with a pin in a two-way link of the clutch lever, the two-way link being designed in such a way that by loading of the positioning lever the pin reaches its first end position along a first path and its second end position along a second path separate therefrom.
- the two end positions ie the first end position and the second end position, correspond to the engaged or disengaged state of the clutch lever. Both end positions are assumed to be stable. Due to the different ways of taking the respective end position, any malfunctions are fundamentally avoided, in contrast to the prior art.
- the first end position may correspond to the “engaged” position of the clutch lever.
- the second end position belongs to its functional position “disengaged”.
- the reverse can also be done.
- the renewed action on the positioning lever results in the pin of the positioning lever reaching and assuming the second end position along the second path, which runs separately from the first path.
- the clutch lever For the ballpoint pen, this corresponds to pressing and releasing the previously described catch again.
- first path and the second path are spatially and functionally separated from one another, so that both the first end position and the second end position of the pin of the positioning lever are inside the two-way link of the clutch lever and thus also the clutch lever as a whole can be taken safely and stably.
- any functional disorders or indifferent functional states cannot fundamentally occur and are not observed according to the invention.
- the design is further made in such a way that the two-way link as part of the clutch lever has at least one separating stop that separates the two ways from one another.
- two separating stops are implemented.
- an evasive stop is provided. The interaction between the evasive stop and the separating stop ensures that the first path and the second path are spatially and functionally separated from one another and that the first end position and the second end position are assumed in a stable manner and without mutual influence.
- two separation stops and one escape stop are provided according to the invention inside the link of the clutch lever.
- the clutch lever carrying the link is advantageously equipped with a center-zero spring.
- the center-zero spring ensures that the link or the clutch lever has and assumes a basic position, from which pivoting movements of the clutch lever and thus also pivoting movements of the link carried by the clutch lever take place against spring force and the center-zero spring.
- Spring ensures a reset starting from this basic position.
- the center-zero spring can advantageously be designed as a leg spring arranged on a bearing pin of the clutch lever that defines an axis of rotation and has a winding section and two legs extending from it. The procedure is usually such that the winding section encloses the bearing pin, which in turn defines the axis of rotation for the clutch lever which can be pivoted relative to the axis of rotation.
- the two legs of the center-zero spring are each arranged on the edge of the clutch lever or act on it accordingly.
- the procedure is usually such that a return spring is assigned to the positioning lever.
- the return spring ensures that the Positioning lever is pretensioned or reset towards a basic position. With the positioning lever, the clutch lever then also moves into a corresponding basic position because the positioning lever controls the clutch lever via the pin connected to it. In order to move the clutch lever via the positioning lever, the force of the return spring assigned to the positioning lever must therefore be overcome.
- the design is advantageously such that the positioning lever is equipped with a drive, for example an electric motor drive.
- a drive for example an electric motor drive.
- manual adjustment of the positioning lever is also possible.
- the positioning lever can now be controlled in such a way that the pin carried by the positioning lever moves within the two-way link as part of the clutch lever and assumes at least the first end position and the second end position. In this way, the position of the clutch lever is controlled and specified via the positioning lever.
- the positioning lever is advantageously equipped with at least two arms, a pin arm carrying the pin and an actuating arm.
- the electric motor drive may act on the actuating arm and thus ensure the corresponding adjustment movements of the positioning lever and thus of the clutch lever.
- an additional third arm is also implemented, but this is basically dispensable. The procedure can continue in such a way that the arms of the positioning lever and thus the positioning lever as a whole are mounted rotatably about a common axis.
- the actuation of the actuating arm of the positioning lever with the help of the electric motor drive can be realized and implemented in every conceivable way.
- the actuation of the actuating arm via the electric motor drive can also take place directly or indirectly.
- an actuator is usually provided between an electric motor and the actuating arm. With the actuator it can This is, for example, a drive wheel on the output side of an electric motor drive, which is set in rotation with the help of an electric motor. The rotations of the drive wheel are then transmitted to the actuating arm and thus to the positioning lever, which in turn pivots about its axis and controls the clutch lever in a corresponding manner with the pin carried by it.
- the secured position of the safety unit and the consequently disengaged position of the clutch lever relative to the actuating lever chain or the actuating lever mechanism belongs to the scenario that a manual actuation of the previously mentioned inside door handle or the outside door handle relative to the locking mechanism is ineffective.
- the electric motor drive for the positioning lever can in principle also open the locking mechanism in question by electric motor, as is described in detail in the generic prior art according to DE 10 2019 133 654 A1.
- the inventive design of the gate as a two-way gate inside the clutch lever with the first path and the second path separated from it and the two stable end positions achieved in each case ensures a particularly functional structure. This prevents any malfunctions. This is where the main advantages can be seen.
- Figure 1 shows the motor vehicle lock according to the invention in its
- Figures 2 to 6 show the transition of the motor vehicle lock according to the invention from the basic position or second end position according to Figure 1 in the transition to the first end position in the illustration according to Figure 6 along a first path and
- Figures 7 to 10 show the travel path of the positioning lever and thus also of the clutch lever, starting from the first end position corresponding to Figure 6 along the second path up to its second stable end position in the illustration according to Figure 10, which corresponds to the previously mentioned basic position Figure 1 coincides.
- the figures show a motor vehicle lock, which is a motor vehicle door lock. This is reduced to its essential elements for the invention.
- the motor vehicle lock or motor vehicle door lock has a locking mechanism 1, 2 made up of a rotary latch 1 and a pawl 2, which is only indicated in FIG.
- the release lever 4 and the clutch lever 9 define a total of an actuating lever chain 4, 5, 9 which, in addition to the release lever 4 and the clutch lever 9, also includes a positioning lever 5.
- the locking mechanism 1, 2 shown in Figure 1 can be opened.
- an opening movement of the locking mechanism 1, 2 shown in the closed state in FIG. 1 corresponds to the fact that the clutch lever 9 is in its engaged state shown in dash-dotted lines.
- An associated safety unit containing the clutch lever 9 is consequently found in its "unlocked” position when the clutch is engaged and assumes its "secured” position when the clutch lever 9 is disengaged.
- the change of the clutch lever 9 from its "disengaged" position shown in solid lines to its "engaged” position corresponds to the fact that the clutch lever 9 performs a pivoting movement in the counterclockwise direction about its axis 10.
- the overall design is such that the actuating lever chain 4, 5, 9 working on the locking mechanism 1, 2 is equipped with the previously mentioned clutch lever 9.
- the clutch lever 9 ensures that the actuating lever chain 4, 5, 9 is closed to actuate the locking mechanism 1, 2.
- the disengaged state of the clutch lever 9 shown in solid lines in Figure 1 means that the actuating lever chain 4, 5, 9 is open.
- Corresponding acts on an actuating lever and thus on the clutch lever 9 are therefore empty with regard to the locking mechanism 1, 2. In such a case, this cannot be opened.
- the previously mentioned positioning lever 5 is provided, which is rotatably mounted about an associated axis 6.
- the positioning lever 5 has a pin 7.
- the pin 7 engages in a two-way link 8 of the clutch lever 9.
- the two-way link 8 is designed in such a way that by acting on the positioning lever 5, the pin 7 reaches its first end position along a first path 11 as shown in FIG. 6 and reaches its second end position along a second path 12 separate therefrom , as shown in Figure 10 and Figure 1.
- the second end position corresponds to the solid position of the clutch lever 9 in Figure 1
- the dash-dotted position of the clutch lever 9 represents the first end position comparable to Figure 6.
- the positioning lever 5 is designed as an adjusting lever, as is basically also provided in comparable motor vehicle locksmiths and in particular in the generic prior art according to DE 10 2019 133 654 A1.
- the pin 7 on the positioning lever 5 can cover the first path 11 within the link 8 of the clutch lever 9 until the pin 7 reaches the first end position in the functional position according to FIG.
- the pin 7 is able to complete the second path 12, starting from the first end position as shown in Figure 6 up to the second end position, as shown in Figure 10 and in the same way in the basic position shown in Figure 1.
- the second end position corresponding to FIGS.
- the first end position in the functional position according to FIG. 6 represents the “unlocked” state of the safety unit and, accordingly, the “engaged” functional position of the clutch lever 9.
- the security unit may fundamentally be a locking unit, a child lock unit, an anti-theft device or even combinations.
- the link 8 is not only designed as a two-way link 8, but is also designed in such a way that when the positioning lever 5 is acted upon, the pin 7 reaches the first end position in Figure 6 along its first path 11 and, after the positioning lever 5 is acted upon again (in the same actuation direction), it moves along the second, separate path 12 to the second end position as shown in Figure 10 or in solid lines in Figure 1. Both paths 11, 12 are spatially and functionally separate from one another.
- the positioning lever 5 is actuated via a drive which, in the exemplary embodiment, is designed as an electric motor drive 15 and is only shown in principle in Figure 1.
- the electric motor drive 15 has an electric motor which works on an output-side driven disk which in turn acts on an actuating arm 5a of the positioning lever 5.
- the positioning lever 5 also has a pin arm 5b, which carries the pin 7 that penetrates into the two-way gate 8.
- a further third arm 5c is also implemented, but this is also basically unnecessary. Both arms 5a, 5b or all three arms 5a, 5b and 5c of the positioning lever 5 are mounted so that they can rotate about the common axis 6.
- the link 8 functions according to the ballpoint pen principle already described in the introduction. Because the one-time and first-time loading of the positioning lever 5 starting from the functional position in Figure 1 or corresponding to the second end position according to Figure 10 leads to the pin 7 arranged on the pin arm 5b of the positioning lever 5 moving into the first End position according to Figure 6 passes over and here, as it were, snaps into place or is held.
- the two-way backdrop 8 is equipped with a separating stop 81 that separates the two paths 11, 12 from each other.
- two separating stops 81, 82 are provided. In addition to the two separating stops 81, 82, you can also see an evasive stop 83.
- the two separating stops 81, 82 are found on both sides of the escape stop 83, which is provided opposite a recess formed between the two separating stops 81, 82, into which the pin 7 enters at the end of the first path 11 and in the first end position according to Figure 6 is held in contact with the separating stop 82.
- the clutch lever 9 is equipped with a center-zero spring 13 that is only indicated.
- the center-zero spring 13 is designed as a leg spring and, with its winding section, encloses the bearing pin defining the axis 10 of the clutch lever 9.
- two legs extending from the winding section are provided.
- the positioning lever 5 is in turn equipped with a return spring 14, which ensures that the positioning lever 5 is in its basic position shown in Figures 1 and 10 or the second stable end position ("secured" of the safety unit or "disengaged" of the clutch lever 9). is transferred.
- the pin 7 on the pin arm 5b of the positioning lever 5 now moves along the first path 11 until the pin 7 reaches the end position shown in FIG. 3 within the link 8. Now the positioning lever 5 is maximally deflected about its axis 6 and ultimately reaches the "engaged" position of the clutch lever 9 shown in dash-dotted lines in FIG. 1. As the pin 7 moves further within the link 8 in the transition from FIG. 3 to FIG The center-zero spring 13 acting on the clutch lever 9 ensures that the clutch lever 9 and thus also the link 8 are reset. Because in the transition from FIG. 1 to FIG. After reaching the functional position in Figure 3, the center zero spring 13 now ensures that the clutch lever 9 and with it the link 8 are reset in the counterclockwise direction, as can be seen from a transition from Figure 3 to Figure 4. Now the pin 7 rests against the avoidance stop 83.
- the associated actuating arm 5a of the positioning lever 5 may be acted upon manually or, according to the exemplary embodiment, with the aid of the electric motor drive 15, as explained in the introduction to the description. I.e., comparable to the ballpoint pen principle already explained, a renewed action on the positioning lever 5 ensures that the previously achieved locking or reaching the first end position in the illustration according to FIG. 6 is canceled by the pin 7 after the first path 11 has been completed and can also be canceled.
- the action of the positioning lever 5 on its actuating arm 5a in a counterclockwise direction about its axis 6 during the transition from FIG. 6 to FIG. 7 now results in the pin 7 being able to leave the lower separating stop 82.
- the center-zero spring 13 is able to act on the clutch lever 9 about its axis 10 in a counterclockwise direction, so that the pin 7 changes from the functional position according to FIG. 7 to the position according to FIG. 8.
- the clutch lever 9 can be reset using the center zero spring 13, which corresponds to the clutch lever 9 and with it the link 8 pivoting anti-clockwise about the associated axis 10, as can be seen in the transition from Figure 9 to Figure 10.
- the positioning lever 5 or the clutch lever 9 has now reached its second end position corresponding to the basic position in Figure 1, as is also shown in Figure 10 at the end of the second path 12.
