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 an actuating lever chain and with at least one electric motor drive for the actuating lever chain, the actuating lever chain having at least one child safety lever, one anti-theft lever and one central locking lever.
- the motor vehicle lock in question is generally and additionally equipped with a locking mechanism consisting essentially of a rotary latch and a pawl.
- a locking mechanism consisting essentially of a rotary latch and a pawl.
- Different functional positions of the motor vehicle lock can be realized and implemented via the actuating lever chain and the at least one electric motor drive working on it.
- the functional position "Child lock on” corresponds to the fact that an associated motor vehicle door (usually one or both of the rear motor vehicle side doors) is locked from the inside. That is, the motor vehicle door in question can be opened from Do not open from the inside, but opening from the outside is possible because there is no corresponding external locking mechanism.
- the actuating lever chain In the "locked” or “centrally locked” functional position, the actuating lever chain is set up in such a way that, in contrast, an external locking is implemented, but the motor vehicle door in question can still be opened from the inside and unchanged, because in this case an internal locking is not reflected.
- the functional position “anti-theft” corresponds to the relevant motor vehicle door being locked both on the inside and on the outside. As a result, the motor vehicle door cannot be opened, neither from the inside nor from the outside, even if the window is broken and in the event of an attempted theft.
- the “locked” or “secured” state of the associated component of the actuating lever chain is usually implemented and implemented in practice in such a way that an associated clutch lever ensures a mechanical interruption. Consequently, the locking mechanism cannot be opened with the (open) actuating lever chain. If, on the other hand, the actuating lever chain or the corresponding part of the actuating lever chain is in the “unlocked” or “unlocked” state, this includes an engaged position of the clutch lever in question. In this case, the actuating lever chain is closed, so that in the unlocked state and, for example, when the actuating lever chain is acted upon manually or by a motor, the locking mechanism can be opened by a release lever lifting the pawl away from its engagement with the rotary latch.
- 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 the structural and monetary outlay is reduced and an embodiment with the lowest possible weight compared to previous designs is observed.
- the invention proposes in a generic motor vehicle lock and in particular motor vehicle door latch that the electric motor drive as the only drive for Realization of a central locking, a child safety device and an anti-theft device is set up and trained.
- the child safety lever, the anti-theft locking lever and the central locking lever are mounted on the same axis as each other.
- a locking clutch lever is additionally provided.
- the locking clutch lever is also and advantageously mounted on the same axis as the child safety lever, anti-theft lever and central locking lever.
- the lockup clutch lever and central locking lever are typically coupled to each other via a spring. In this way, the central locking lever and the locking clutch lever can perform a mutual relative movement to one another, but are nevertheless each moved back into a specific relative position after a deflection by the spring.
- the locking clutch lever has an actuating pin for acting on the anti-theft lever.
- the lockup clutch lever is usually equipped with two control arms. The two control arms engage alternately or together in a recess in the drive. In addition to the two control arms, another control arm of the central locking lever also engages in the relevant recess of the drive.
- the recess in question is generally found on or in a gear wheel of the drive.
- the gear wheel is usually the gear wheel on the output side.
- the electric motor drive mostly has a driven worm, which interacts with a driven gear wheel or first gear wheel.
- This drive gear wheel or first gear wheel is also and advantageously equipped with an embedded spring, which as a whole returns the electromotive drive to its starting position after it has been acted upon or has been adjusted. This typically applies to both rotational movements that can be implemented using the output gear, i. H. both clockwise and counterclockwise.
- the output gear wheel or first gear wheel can now interact with the output-side gear wheel or second gear wheel in question, in which the recess in question is located.
- the second gear wheel in question usually also has an actuating contour for at least the child safety lever.
- the two control arms of the locking clutch lever or optionally only one of the two control arms and also the other control arm of the central locking lever engage in the recess on the output-side gear wheel or second gear wheel.
- the central locking lever as well as the locking clutch lever can be acted upon with the aid of the relevant output-side gear wheel of the electric motor drive.
- the actuating contour on the gear wheel is able to act on the child safety lever. In most cases, the actuating contour in question is also used in order to act on the anti-theft locking lever, in particular to return it to its initial position.
- a motor vehicle lock and in particular a motor vehicle door lock, is made available which is designed to be particularly compact, inexpensive and lightweight compared to the prior art and yet works reliably.
- the electric motor drive for the realization of the central locking, the child safety device and the anti-theft device acts as the only drive and expressly no further second or even more drives are provided. Rather, the sophisticated further kinematics ensure that the individual functional positions can be separated from one another without any problems.
- the paraxial is predominantly responsible for storing the child safety lever, the anti-theft lever and the central insurance lever in conjunction with the locking clutch lever.
- the concept of the central locking lever also includes and covers embodiments that do not necessarily have a central locking system for all motor vehicle locks in a motor vehicle or are linked thereto. Rather, the central locking lever can, quite fundamentally, also be a locking lever that is implemented singularly. Since there are usually several motor vehicle locks in a motor vehicle and these are moved centrally to their “unlocked/locked” position, the locking lever in question is typically designed as a central locking lever.
- FIG. 1 shows the motor vehicle lock according to the invention in a front view
- FIG. 2 shows the object according to FIG. 1 in a rear view
- FIG. 3 shows the motor vehicle lock according to FIGS. 1 and 2 during a central locking process in a front and rear view
- FIGS. 1 and 2 shows the motor vehicle lock according to FIGS. 1 and 2 in the course of the child safety device in a front and rear view
- Fig. 6 and 7 schematically an unlocking process or the interpretation of the anti-theft device as well as the child safety device.
- the motor vehicle lock according to the invention is shown schematically and in an overview in the form of a motor vehicle door lock.
- this has a locking mechanism 1, 2 consisting essentially of a rotary latch 1 and pawl 2 in a mostly horizontal locking mechanism plane.
- an actuating lever chain 3, 4, 5, 6, 7, 8, 9 is realized, which is shown reduced to its essential components according to the exemplary embodiment and, in contrast, extends in a vertical plane.
- an electric motor drive 10, 11, 12 for the actuating lever chain 3 to 9 is provided.
- the actuating lever chain 3 to 9 has at least one child safety lever 3, an anti-theft lever 4 and a central locking lever 5.
- the actuating lever chain 3 to 9 also has an inner clutch lever 6, an outer clutch lever 7 and a transmission lever 9 and finally a locking clutch lever 8.
- the electric motor drive 10, 11, 12 is in turn composed of an electric motor 10 and a driven worm wheel or drive wheel 11 as the first gear wheel.
- the output worm wheel 11 is rotated using a worm located on the output shaft of the electric motor 9 .
- the output worm wheel 11 is equipped with an embedded spring 13, with the help of which the electric motor drive 10, 11, 12 is returned to its basic position after being acted upon.
- the driven wheel 11 or first gear wheel 11 meshes with a second gear wheel 12, which represents the output-side gear wheel 12 of the electric motor drive 10 to 12.
- FIGS. 1 and 2 A comparison of FIGS. 1 and 2 shows that the second gear wheel 12 of the electric motor drive 10 to 12 has a radial recess 14 .
- the central locking lever 5 engages in the recess 14 with a control arm 5a.
- two further control arms 8a, 8b as components of the locking clutch lever 8 can engage in the recess 14, either alternatively or together, as will be explained in more detail below.
- the central locking lever 5 in question also engages with an extension arm 5b in a recess of the transmission lever 9, so that it is caused to rotate in a predominantly horizontal plane parallel to the locking plane.
- Child lock lever 3, the anti-theft lever 4 and the Central locking lever 5 are each mounted on the same axis as one another, namely in relation to a common axis 15.
- the locking clutch lever 8 is also mounted on the same axis.
- the locking clutch lever 8 is elastically coupled to the central locking lever 5 via a spring 16 .
- a lug 8c provided on the locking clutch lever 8 can interact with a switch or generally with a sensor 17 in order to transmit the “locked” or “centrally locked” position to a control unit, which is not shown in detail.
- the second gear wheel or gear wheel 12 is equipped not only on its rear side, which can be seen in FIG . Instead, the second gear wheel or gear wheel 12 in question is also equipped with an actuating pin 12a on the front side, with the help of which the anti-theft lever 4 and, according to the exemplary embodiment, the child safety lever 3 can be acted upon, as will be explained in more detail below.
- the central locking lever 5 has also actuated the inner clutch lever 6, but this does not change the fact that the outer clutch lever 7 has been "disengaged", so that external actuation of the motor vehicle lock shown is not (or no longer) possible.
- the locking clutch lever 8 and the central locking lever 5 are also aligned against each other again with the help of the spring 16 coupling the two levers 5, 8, so that this the sensor or switch 17 is actuated and the assumption of the locking state is reported to the control unit, not shown.
- clutch lever 8 and also the control arm 5a of the central locking lever 5 can enter the recess 14.
- the actuating contour 12a on the second gear wheel 12 acts on the child safety lever 3 in such a way that the child safety lever 3 is pivoted clockwise about the common axis 15 in the front view and thereby actuates the inner clutch lever 6, which in turn acts on the locking clutch lever 8 and transfers it to its "disengaged" position.
- Fig. 5 the insertion of the anti-theft device is shown.
- the second gear wheel 12 is again acted upon in the anti-clockwise direction and as a result of this the locking clutch lever 8 is pivoted about the common axis 15 in the clockwise direction in the front view of FIG this entrains in its clockwise movement about the common axis 15.
- the inner clutch lever 6 is first applied and in addition, a second anti-theft device lever 18 mounted coaxially with the transmission lever 9 is pivoted.
- FIG. 6 shows unlocking starting from the centrally locked or anti-theft position.
- each of the lockup clutch lever 8 and the anti-theft lever 4 is returned to its original position.
- Fig. 7 the resetting of the child safety lever 3 is shown graphically.
