Definitions
- Motor vehicle lock in particular motor vehicle door lock
- 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, furthermore with an electric motor drive for a security unit, and with a clutch lever as part of the security unit, the drive being at least linear in the thrust direction movable thrust element on the clutch lever to take the “locked/unlocked” positions of the safety unit works.
- the “locked” position of the safety unit generally corresponds to the “disengaged” position of the clutch lever.
- an actuating lever chain for acting on the clutch lever is mechanically interrupted, so that, starting from a main closed position, for example, the pawl cannot be lifted from its latching engagement with the rotary latch. If, on the other hand, the safety unit assumes its “unlocked” position, this includes the “engaged” state of the clutch lever.
- the actuating lever chain is mechanically closed and the pawl can be lifted from its engagement with the rotary latch by acting on, for example, an inside door handle or outside door handle via the engaged clutch lever and a release lever.
- the security unit can be designed, for example, as a locking unit.
- the operating lever chain is usually an external operating lever chain, which can be transferred to its “unlocked/locked” positions accordingly.
- an associated outside door handle is able or not able to open the lock.
- the security unit can also be one Act as a child safety device or an anti-theft device.
- the motor vehicle lock in question is typically provided on rear motor vehicle side doors and, in the case of an interior operating lever chain, ensures the “child-proof/child-unlocked” functional positions.
- the security unit is implemented on both an internal operating lever chain and an external operating lever chain and in this way the functional positions “theft-proof/theft-unlocked” can be implemented.
- the generic state of the art according to DE 10 2013 019 938 A1 involves the clutch lever acting on the locking unit or security unit and being able to be operated against the force of a spring using the electric motor drive.
- the locking unit has a control contour, whereby the clutch lever interacts with the control contour. This is intended to ensure a robust and reliable function and safe engagement of the individual security positions of the motor vehicle lock.
- the state of the art has generally proven itself, but still offers room for improvement.
- the known embodiment not only requires a reliably operating electric motor drive and consequently an appropriately designed electric motor.
- the electric motor in question must also have enough power to be able to realize and implement the individual functional positions. This is associated with the general disadvantage that such powerful electric motors are not only expensive, but also lead to an increased weight of a motor vehicle lock equipped with them.
- the present invention is based on the technical problem of creating such a motor vehicle lock and in particular a motor vehicle lock.
- a generic motor vehicle lock and in particular a motor vehicle door lock within the scope of the invention is characterized in that the thrust element for acting on the clutch lever moves against an arcuate edge of the clutch lever that is increasingly immersed in the thrust direction.
- the design is usually such that the edge of the curve has a growing radius in the direction of thrust.
- the design is usually such that the clutch lever is rotatably connected to an actuating lever. What is particularly important in this context is that the clutch lever acted upon by the actuating lever is advantageously increasingly immersed in the thrust direction with the help of a contour along its actuation path.
- the procedure is initially such that the thrust element is moved in the thrust direction (linearly) in order to be able to act on the clutch lever.
- the security unit typically moves from its “unlocked” position to the “secured” functional position. This corresponds to the fact that the clutch lever, which is initially engaged in the “unlocked” functional position of the safety unit, is disengaged using the thrust element. As a result of this, the security unit also changes to its “secured” functional position.
- the electric motor drive moves in the thrust direction.
- the thrust direction corresponds to a linear movement of the thrust element.
- the linear movement of the thrust element therefore determines the direction of thrust.
- the thrust element moves against the curved edge of the clutch lever, which increasingly dips in the thrust direction.
- the electric motor drive can be operated according to the invention and at the beginning of its travel along the thrust direction at high speed and then the thrust element increasingly hits the arc edge of the clutch lever that dips into the thrust direction, so that the Clutch lever as a whole is transferred from its previously assumed “engaged” position to the “disengaged” position.
- the reverse can also be done.
- the clutch lever acted upon by the actuating lever increasingly dips into the thrust direction along its actuation path using the (stationary) contour.
- the invention is based on the knowledge that in order to act on the clutch lever, the clutch lever is first of all rotatably connected to the actuating lever.
- the operating lever can generally be an internal operating lever or an external operating lever.
- the clutch lever is spaced from the thrust element at the beginning of its actuation path.
- the thrust element usually has a (front) rectangular contour, which interacts with the curved edge of the clutch lever. That is, at the beginning of the actuation path of the clutch lever, the curved edge is spaced from the rectangular contour of the thrust element in question.
- the clutch lever moves along its actuation path with the help of the contour and the contour as a whole ensures that the curved edge of the clutch lever increasingly dips into the thrust direction, i.e. H. is moved towards the rectangular contour of the thrust element - at least in projection.
- the clutch lever has a distance from the rectangular contour of the thrust element at the beginning of its actuation path, which is predetermined by the contour. Due to this distance, the electric motor drive for acting on the thrust element can work at high speed along the direction of thrust at the beginning of the travel path of the thrust element and, as it were, gain "momentum” because the rectangular contour on the thrust element does not initially move against the curved edge of the coupling element. Only when a certain amount of the travel path of the thrust element is completed in the thrust direction, the rectangular contour usually provided on the front of the thrust element reaches the edge of the arch.
- the front rectangular contour of the thrust element moves tangentially against the edge of the arch and in this way ensures ensures that the clutch lever is pivoted relative to the actuation lever.
- the clutch lever transitions from its generally assumed “engaged” state to its “disengaged” state.
- the actuating lever is actuated with the clutch lever rotatably connected to it, the disengaged clutch lever moves past the stop edge of the release lever and consequently the locking mechanism cannot be acted upon because the clutch lever has an idle path relative to the release lever and consequently also the locking mechanism.
- the electric motor drive can be designed to be significantly less powerful compared to the prior art or the invention opens up the possibility that the electric motor drive is still able to reliably and unchanged even in the event of any malfunctions or declining performance due to aging effects To be able to move to the “secured/unsecured” positions of the security unit.
- the design is usually such that the curved edge of the clutch lever extends perpendicular to its main plane.
- the procedure is typically such that the actuation lever and the clutch lever span a common actuation plane with their respective main planes.
- the operating lever is rotatably mounted in the operating plane in question. This means that the clutch lever and the actuation lever have a largely identical main plane, which defines the common actuation plane. This allows both the actuation lever and the clutch lever to be pivoted in the actuation plane in question.
- the thrust element is generally equipped with a toothed segment for engagement with a gear of the drive.
- the gear of the drive may be arranged on an output shaft of the drive.
- one or more gear wheels can also be implemented at this point.
- the electric motor drive is only equipped with an electric motor and the gear in question on its output shaft, with the gear engaging with the toothed segment of the thrust element.
- the toothed segment in question on the thrust element usually extends in a straight line, because the thrust element is moved linearly along its thrust direction using the electric motor drive.
- FIG. 1 shows the motor vehicle lock according to the invention in the form of a motor vehicle door lock in a perspective view
- Fig. 2 shows the motor vehicle lock according to Fig. 1 in the “unlocked” functional position of the security unit and with the clutch lever engaged
- Fig. 3 shows the object according to Fig. 2 with the safety unit “secured” in its functional state and with the clutch lever disengaged.
- the figures show a motor vehicle lock, which is a motor vehicle door lock.
- the motor vehicle lock has a locking device 1, 2, which is only indicated in FIG Security unit 5 realized.
- the clutch lever 5 and the safety unit 5 coincide, which of course only applies as an example and is in no way restrictive.
- the electric motor drive 3, 4 works on the clutch lever 5 using a thrust element 6 that can be moved at least linearly in a thrust direction S. In this way, the “secured/unlocked” positions of the security unit 5 can be assumed.
- the design is such that in order to change the functional position of the safety unit 5, the thrust element 6 for acting on the clutch lever 5 moves against a curved edge 5a of the clutch lever 5 which increasingly dips in the thrust direction S.
- the curved edge 5a on the clutch lever 5 has an increasing radius Ri, R2 in the In fact, the radius of the arc edge 5a grows from an initial value Ri to a final value R2 along the shear direction S.
- the thrust element 6 is equipped on the front with a rectangular contour 6a, which interacts with the curved edge 5a of the clutch lever 5.
- the overall design is such that the rectangular contour 6a with an edge 6ai moves in the thrust direction S against the curved edge 5a of the clutch lever 5 as soon as the thrust element 6 is moved in the thrust direction S using the electric motor drive 3, 4.
- the other further edge 6a2 of the front rectangular contour 6a of the thrust element 6 ensures that with its help the curved edge 5a is guided at the edge.
- the design is such that the curved edge 5a of the clutch lever 5 extends perpendicular to the main plane of the clutch lever 5.
- the main plane of the clutch lever 5 coincides with the plane of the drawing.
- the design is such that the clutch lever 5 is rotatably connected to an actuating lever 7.
- the actuating lever 7 is, and not limited to, an internal actuating lever.
- the actuating lever 7 is also equipped with a main plane which, according to the exemplary embodiment, coincides with the plane of the drawing. In this way, the actuating lever 7 and the clutch lever 5 with their respective main planes form a common actuating plane which coincides with the plane of the drawing.
- This counterclockwise rotation of the release lever 10 means that, in accordance with a comparison with FIG.
- the locking mechanism 1, 2 is opened and a previously caught locking bolt is released.
- the associated motor vehicle door can be opened.
- the design is such that the clutch lever 5, acted upon by the actuating lever 7, increasingly dips into the thrust direction S along its actuation path using the contour 11 in question, ultimately and essentially with the curved edge 5a.
- the result of this is that the curved edge 5a of the clutch lever 5 at the beginning of the actuation path, as shown in solid form in the enlarged view in FIG. 2, is spaced from the rectangular contour 6a at the front of the thrust element 6.
- the clutch lever 5 and consequently also the curved edge 5a dip more and more into the thrust direction S. This is shown in dash-dotted lines in the excerpt in question.
- the design within the scope of the invention is such that the clutch lever 5 is arranged in the starting position as shown in FIG. 2 with the curved edge 5a spaced apart from the rectangular contour 6a of the thrust element 6. In fact, there is a distance A at this point.
- This distance A means that the clutch lever is acted upon
- the electric motor drive 3, 4 With the help of the thrust element 6, the electric motor drive 3, 4 initially completes a kind of “freewheel” and can in this way gain “momentum”.
- the design is such that the electric motor drive or an electric motor 3 implemented at this point is equipped on its output shaft with a pinion 4, which engages in a toothed segment 6b of the thrust element 6.
- the toothed segment 6b runs linearly, so that the thrust element
- the pusher element 6 Due to the previously described distance A of the curved edge 5a in the undeflected state of the clutch lever 5 and at the beginning of the travel path of the thrust element 6, the pusher element 6 initially completes a certain travel path in the thrust direction S until the rectangular contour 6a comes into contact with the curved edge 5a of the clutch lever 5 comes.
- the electric motor drive 3, 4 can start at a relatively high speed at the beginning of its travel movement and only then ensures the adjusting movement on the clutch lever 5.
- the curved edge 5a increasingly dips into the thrust direction S of the thrust element 6 and with the growing radius Ri, R2 is equipped, the front rectangular contour 6a of the thrust element 6 moves tangentially along the curved edge 5a of the coupling element 5.
- the coupling element 5 is pivoted increasingly and “gently” and with relatively little force about its axis 9 in the clockwise direction during the transition from FIG. 2 to FIG. 3.
- the pivoting movement of the coupling element 5 takes place against the force of a spring 11, which biases the coupling lever 5 in the direction of its “coupled” position shown in FIG. 2.
- the functional position in FIG. 3 of the clutch lever 5 is reached “disengaged”.
