Definitions

• the invention relates to a motor vehicle door lock, with a locking mechanism consisting of a regular rotary latch and pawl acting thereon, furthermore with at least one locking lever, preferably a central locking lever, and with at least one (electro) motor drive.
• at least one actuating lever for inside and / or outside actuation can be implemented.
• a motor vehicle door lock of the design described at the outset has become known, for example, from the German Disclosure Corporation 196 27 246 A1.
• a. describes a device for quick unlocking of the door lock, which has been referred to there as a quick release.
• it is a lifting magnet which is moved to switch over from a functional position "additionally secured” (secured against theft) to a functional position "unlocked”.
• the pawl and the release lever work together so that when the (external) actuation lever is actuated, the pawl is lifted off the rotary latch and an associated motor vehicle door can be opened.
• the electronic control unit sends associated signals to at least one of the door locks of the motor vehicle, which is then opened automatically, as it were, by means of actuating elements.
• a motor vehicle door lock is known for example from DE 38 20 248 C2.
• the invention is based on the technical problem of developing a motor vehicle door lock of the design described at the outset in such a way that a practically instantaneous opening of an associated motor vehicle door succeeds with a particularly low outlay in terms of design.
• the invention proposes, in the case of a generic motor vehicle door lock, that a locking lever which is in engagement with the locking lever - preferably in its locking and / or anti-theft position - is provided for quick unlocking, which is operated with the aid of the (electro) motorized Drive in the course of the quick release is separated from this (the locking lever), so that the locking lever m can be transferred to its unlocked position.
• This can be done actively or passively.
• the locking lever is free after quick unlocking and can be transferred to the unlocking position in question, for example, with its own actuator m.
• the procedure is regularly such that the locking lever moves automatically, preferably spring-loaded, in the course of the quick release, m the unlocking position.
• quick unlocking means that the motor vehicle door lock in general immediately from the position “additionally secured” or “theft-proof” or “ver ⁇ e- The unlocking position can then be transferred. Following this, an associated motor vehicle door can then be opened by triggering the actuating lever (or otherwise). It is conceivable that the described actuating lever is acted upon by an outside door handle, so that the pawl is removed from the door The catch can be lifted off and the door can consequently be opened. In principle, the quick release can then be followed by a conventional release of the actual locking mechanism.
• motor vehicle door lock means any locks, that is to say not only those for side doors, but also, for example, for trunk lids, tailgates or bonnets, even fuel fillers or the like.
• electrical opening means that the pawl is lifted or lifted out of its engagement or latching with the rotary latch by means of (electro) motor force.
• the locking lever has two locking receptacles for realizing the functional positions “locked” and “theft-proof” or for defining the positions “locking position” and “theft-proof position”. These locking receptacles can each interact with a locking lug on the locking lever, the mode of operation being similar to that described in German patent application 199 34 128.1. This will be discussed in more detail with reference to the description of the figures.
• the two aforementioned snap-in receptacles can be designed as circular arc receptacles with a different radius compared to the axis of rotation of the locking lever. This results in different positions of the locking lever, on the one hand in the "locked position” and on the other hand in the "anti-theft position". This is regularly necessary to ensure that the actuating lever can lift the locking lever out of the locking receptacle, for example in the "locking position”. In contrast, such a procedure in the "anti-theft position" of the motor vehicle door lock is (no longer) possible and also not desirable. Because in this functional position, the operating lever performs a freewheel.
• the locking lever has a pin which interacts with the locking lever.
• This pin can engage a pin receptacle on the locking lever.
• an (anti-theft) anti-theft lever is also provided.
• This anti-theft lever can be used in the course of the quick release by means of the locking lever from the "anti-theft" function position. position "theft-proof” are transferred.
• the pin receptacle on the locking lever is lifted off the pin on the locking lever, so that this pin and thus the locking lever is released. This is achieved by means of the motor drive already described, which acts on the locking lever accordingly.
• the locking lever can also be assigned a spring-loaded or spring-loaded transmission lever which, when acted upon by the (electro) motor drive, takes the locking lever with it for quick unlocking.
• this is done simply by the fact that the transmission lever and the locking lever are mounted on a common axis and are usually at least partially overlapping each other and the transmission lever ensures the above-described "take-along" with an edge resting on the locking lever in the course of the quick release.
• the transmission lever dodges the drive. This is necessary so that the drive can perform an additional function within the scope of the invention, namely not only the quick adjustment but also the central locking function.
• the locking lever has a longitudinal recess and that it is displaceably mounted with spring support.
• the (electro) motorized drive engages an actuating contour of the locking lever.
• the locking lever In the opposite direction of actuation (of the (electro) motor drive) the locking lever (m more similar) Way as described above), with the help of the longitudinally displaceable storage.
• the (electro) motor drive is used both to implement the central locking function (and possibly also the anti-theft function) and to display the quick-release function and an electric motor with a driven wheel or Has driven pulley and eccentric control cam.
• This control cam engages in at least one fork receptacle on the locking lever for the representation of the (central) locking position.
• Two fork receptacles are preferably provided, namely in order to be able to implement the “locking position” and one in order to be able to “position the anti-theft device” (provided that no additional anti-theft device lever is implemented).
• control cam not only interacts with the transmission lever and / or the actuating contour on the locking lever, but also - as described - with one or both fork mounts on the locking lever.
• the (electro) motor drive continues to perform the function of being able to transfer the locking lever, in particular the central locking lever, to its "locking position" and / or "anti-theft position".
• no further drive is required, which is associated with cost advantages.
• considerations of the invention aim to adjust the optional anti-theft lever by means of the one (electro) motor drive.
• an additional second drive is mostly used here.

If the output disk 11 and thus the control cam 12 - driven by the electric motor 9 - rotates clockwise (direction "unlocking position" E), this control cam 12 strikes the transmission lever 21 after about a quarter of a turn. Since the transmission lever 21 and the locking lever 13 are arranged in mutually parallel planes with partial overlap and are rotatably mounted on a common axis 22, this striking of the control cam 12 leads to the transmission lever 21 taking the locking lever 13 with an edge 23. The locking lever 13 rotates counterclockwise here - represented by the arrow in the direction of "unlocking position" E.
