Definitions
- the present invention relates to a motor vehicle door lock according to the preamble of claim 1.
- Motor vehicle door lock here is generally to be understood as a side door lock, a rear door lock, a tailgate lock, a hood lock or the like of a motor vehicle.
- the known motor vehicle door lock furthermore has a gear in the form of a worm rotatable by the drive with an associated worm wheel, which carries as a control element a driving pin that can be displaced along a peripheral section against spring force.
- the driver pin can swing out a pawl of the motor vehicle door lock to release an assigned lock latch.
- the driver pin After swiveling out the pawl, the driver pin runs onto a stop on the pawl, which blocks the further movement of the driver pin. When the driver pin reaches a trailing position along the peripheral portion, the drive is blocked and then switched off.
- the displaceable mounting of the driver pin on the worm wheel can be viewed as a coupling between the drive and the actuating element.
- the present invention is based on the object of specifying a motor vehicle door lock which prevents an unwanted blocking of a lock element, in particular a pawl, even in the event of a drive failure and in particular has a higher functionality.
- a basic idea of the present invention 'to provide a coupling which engage only upon actuation of the motor vehicle door lock associated inner handle or the outside handle so to produce an operative connection between a drive and a moving lock member thereof. Otherwise, the clutch preferably remains open. Accordingly, the lock element, in particular a pawl, can assume a desired position, in particular lock an assigned lock latch, even if the drive fails - regardless of the failure position of the drive or an assigned actuating element.
- the coupling according to the proposal also enables the drive to be used for further functions independently of a movement of the actuating element or of the lock element. Accordingly, a greater variety of functions of the motor vehicle door lock is made possible. Further details, features, goals and advantages of the present invention are explained in more detail below with reference to the drawing of a preferred exemplary embodiment. It shows:
- Figure 1 is a schematic side view of a proposed motor vehicle door lock.
- Fig. 2 - a plan view of the motor vehicle door lock.
- FIG. 1 and 2 show a simplified schematic representation of a proposed motor vehicle door lock 1 with a motorized drive 2, in particular formed by an electric motor.
- a drive 3 is connected to the drive 2, via which the drive 2 can drive a control element 4, which is designed here as a pin.
- the actuating element 4 can preferably be moved along a circumferential, here circular movement path by the drive 2.
- the actuating element 4 can in turn - here via an actuating lever 5 - a lock element - here a ratchet latch 6 - actuate or move.
- the motor vehicle door lock 1 has a fork or. Rotary latch trained lock latch 7 to which the ratchet 6 is assigned. 1 and 2 show the proposed motor vehicle door lock 1 in the closed state, ie when the lock latch 7 is locked.
- FIG. 1 shows that the pawl 6 in the latched state in a catch 8 - a main catch or possibly a catch - the Lock latch 7 is latched, thereby locking the lock latch 7 against opening.
- one of the fork area 9 is the lock latch . 7 locking block not shown. 1 and 2, however, show the bearing or pivot axis 10 of the lock latch 7.
- the drive train formed from the drive 2 to the lock element to be moved or actuated - here the pawl 6 - has a clutch 11.
- the clutch 11 serves to interrupt this drive train.
- the clutch 11 is installed between the drive 2 and the actuating element 4, preferably between the gear 3 and the actuating element 4.
- the clutch 11 can optionally also include the actuating element 4 and / or the lock element or the pawl 6, this or they therefore form an element of the clutch 11.
- the clutch 11 is assigned a control means 12 which serves to control the engagement and disengagement of the clutch 11.
- FIG. 1 it is indicated that an inner handle 13 assigned to the motor vehicle door lock 1 and / or an outer door handle 14 assigned to the motor vehicle door lock 1 can be coupled with the coupling 11 via the control means 12, so that the coupling 11 when actuated of the inner handle 13 and / or of the outer handle 14 or of a switch or the like assigned to the handles 13, 14, that is to say here creates an operative connection between the drive 2 and the actuating element 4.
- the coupling of the clutch 11 or of the control means 12 to the inner handle 13 and / or the outer handle 14 can be implemented electrically, for example. However, this coupling is preferably carried out mechanically, as in the preferred embodiment described in more detail below.
- the control means 12 acts mechanically on the clutch 11 and includes a clutch lever 15, which may cause an engagement (closing) of the 'coupling.
- the clutch lever 15 can in turn be actuated by an inner operating lever 16 and / or an outer operating lever 17 of the motor vehicle door lock 1.
- the inner operating lever 16 is shown in dashed lines to improve clarity.
- the inner actuation lever 16 can be coupled to the inner handle 13, as indicated by dashed lines in FIG. 1, for example via a linkage, a Bowden cable or the like.
- the outer actuation lever 17 can be coupled to the outer handle 14.
- the inner actuating lever 16 is designed as a two-armed lever and is pivotably mounted about an axis 18, which also serves a pivot bearing of the pawl 6.
- the inner operating lever 16 has a transversely protruding projection 19 at one end of the lever, which projects under or overlaps the coupling lever 15 for pivoting the coupling lever 15. .
- the outer operating lever 17 is pivotally mounted about an axis 20, which also serves to pivot the clutch lever 15.
- the outer operating lever 17 is also designed as a two-armed lever. It has a transversely projecting projection 21 which engages over or under the clutch lever 15, so that when the outer operating lever 17 is pivoted - clockwise in FIG. 1 - the clutch lever 15 is pivoted accordingly.
- the clutch lever 15 is essentially L-shaped and has a run-up surface 22 facing the clutch 11 with a run-up slope 23 which cooperates with a clutch element 24 in such a way that the clutch 11 is closed or opened depending on the pivoting position of the clutch lever 15 is.
- the coupling element 24 is designed here in the form of a pin, the run-up surface 22 or bevel 23 being able to act on an end face of the coupling element 24 in such a way that the coupling element 24 is axially displaced depending on the pivoting position of the coupling lever 25.
- This axial movement or displacement controls the engagement and disengagement of the clutch 11.
- the clutch 11 has two toothed wheels 25 and 26, each having an axial toothing 27 and arranged on a common axis 28 or coaxially, so that the toothed wheels 25 and 26 are in engagement with one another via their toothings 27 in the axially compressed state. The clutch 11 is closed or engaged in this state.
- the serrations 27 of the gears 25 and 26 are preferably matched to one another and designed in such a way that engagement in virtually any relative position of the gears 25 and 26 to one another is possible - the serrations 27 are therefore of very fine design - and that only one engagement in a drive direction or drive direction of rotation, the clutch 11 thus transmits forces at least essentially only in one drive direction - here to the actuating element 4.
- the functional element 24 is arranged centrally on the gearwheel 26, that is to say in extension to the axis 28, and projects toward the clutch lever 15 or its run-up surface 22.
- the gear 26 also carries the actuating element 4, which is arranged eccentrically and fixedly on the gear 26 on the output side.
- the gear 25 forms an element of the transmission 3 in the illustrated embodiment.
- the gear 25 is designed as a worm gear that can be rotated by the drive 2 via a meshing worm 29 of the gear 3.
- the electric motor drive 2 the transmission 3 and / or the clutch 11 are also possible.
- the clutch 11 it is not necessary for the clutch 11 to be designed to transmit rotary movements.
- translatory movements can also be transmitted or coupled.
- the drive 2 can, for example, instead of an electric motor, have a magnetic, pneumatic, hydraulic actuator, a linear motor or the like.
- the gear 3 is adapted or omitted.
- the clutch 11 is closed via the control means 12, here via the pivoting clutch lever 15.
- the drive 2 becomes a sensor, for example by a switch (not shown) assigned to the inner handle 13 and or the outer handle 14 o. The like. Or control electronics, not shown, evaluating corresponding signals switched on.
- the drive 2 then works in a direction of rotation which, due to the closed clutch 11, leads to an actuation or movement of the actuating element 4.
- the actuating element 4 performs a circular movement due to the present constructive solution and pivots the associated actuating lever 5 such that it lifts the pawl 6 or disengages from the catch 8 and thus releases the lock latch 7.
- the motor vehicle door lock 1 is then opened.
- the drive 2 can be switched off. This can be achieved, for example, by means of a sensor, switch or the like, not shown, or by running the actuating element 4 onto a stop, not shown, or the like. However, the drive 2 can also remain switched on, so that the actuating element 4 is moved further along its path of movement in order to pivot the actuating lever 5 back and thus release the pawl 6.
- the actuating lever 5 is preferably designed with two arms and is pivotably mounted about an axis 30. However, other constructive solutions are also possible here.
- the pawl 6 and / or the actuating lever 5 is or are spring-loaded in such a way that when the clutch 11 is open, moving or pushing the actuating element 4 or resetting the 'actuating lever 5 and / or the pawl 6 by spring force is possible. Accordingly, even if the drive 2 fails or the transmission 3 is blocked, the pawl 6 can engage and lock the latch 7 when the motor vehicle door lock 1 is closed.
- the opening of the clutch 11 and thus the release of the pawl 6 or another lock element actuated by the drive 2 takes place in any case when the handles 13 and 14 are no longer actuated and the clutch lever 15 - in particular by means of a corresponding pretension by means of a spring, not shown - its neutral position shown in Figure 1 • -. which the coupling non-closing position - occupies.
- An emergency opening function is provided in order to enable the motor vehicle door lock 1 to be opened even if the drive 2 fails, the transmission 3 or the like is blocked.
- This can be realized, for example, in that the inner handle 13, the outer handle 14, a lock cylinder (not shown) or the like is coupled to the pawl 6, preferably via a sufficient lost motion, such that, for example, actuation of the inner handle beyond the normal open position 13, the outer handle 14 or the lock cylinder, not shown, leads to a lifting of the pawl 6 and thus release of the lock latch 7.
- the drive 2 can also be used for further functions of the motor vehicle door lock 1, in particular actuating functions or the like.
- the clutch 11 is preferably only closed or engaged when the handle 13 or 14 is actuated. Otherwise, the clutch 11 is open or disengaged, so that the drive 2 is switched on without actuation or movement of the actuating element .4 or the associated lock element and, for example, further functions via the gear 3 or another gear can perform.
- the drive 2 is operated in the opposite drive direction, the coupling not acting in this drive direction, even in the engaged or closed state, or no significant forces acting on the actuating element 4 or the associated lock element - here the pawl 6 - exercises.
- a very compact structure of the proposed motor vehicle door lock 1 is achieved in that the axes 10, 18 and 20 run parallel, whereas the axis 28 of the coupling 11 and the axis of rotation of the drive 2 are perpendicular to this and preferably also to one another.
