Abstract

The device has a locking mechanism, at least one locking lever (9), preferably a central locking lever, at least one motorized drive (11-14) and a rapid unlocking lever (17) associated with the locking lever. The locking mechanism is connected to the locking lever via the rapid unlocking lever, which releases the locking mechanism with the aid of the drive irrespective of the position of the locking lever.

Description

The invention relates to a motor vehicle door lock, with a locking mechanism, at least one locking lever, preferably central locking lever, at least one motor drive, and with a central locking lever associated quick release lever.

The motor drive usually ensures that the Central locking lever "locked" into its positions or "unlocked" is convertible. Basically you can with the central locking lever (or independent hereof) another position in the sense of "theft-proof" represent. The quick release lever supports the process of so-called quick release. Such a quick release is usually then instead, when so-called "keyless entry" systems are used come.

In such devices leads a vehicle user an identification device (eg code card) with itself, whereby approaching the vehicle user to the Vehicle or when operating the outside door control (door handle) a dialogue between the vehicle and the aforementioned Identification device is initiated. In the course of This dialogue becomes the access authorization of the Vehicle user checked. If appropriate Authorization has been proven, send in the Dialogue initiating and monitoring electrical control unit associated signals to at least one of the door locks of the motor vehicle, then motor, as it were automatically, opened with the help of control elements or is unlocked. Such a motor vehicle door lock is described in the context of DE 38 20 248 C2.

In the event that a door lock with such a Keyless entry system is equipped, the requirement arises especially with additional use of a Theft protection device, the time duration of the Initiation of the opening process until the opening ability the equipped with the door locks motor vehicle doors set as low as possible. Otherwise you have to Comfort restrictions are feared.

It is therefore necessary, as it were immediately after introduction the opening procedure and positive examination of the Authorization of the vehicle user the locking in the Condition "unlocked" to convict, so that the operator a associated motor vehicle door can open without delay.

To realize this quick release, beats the known doctrine, from which the invention proceeds, with a the locking lever or central locking lever in Engaged locking lever as a quick release lever in front. This locking lever is using the motor Drive in the course of the quick release of the locking lever separated, so that the locking lever in its unlocking position can be converted (see WO 01/33017 Al).

These measures have basically proven to require however, that the locking lever in the course of quick release the unlocked position actively or passively occupies. That may then lead to delays when the locking lever or central locking lever connected move complex lever mechanism during this process got to. - Here the invention wants to remedy the situation.

The invention is based on the technical problem, a generic motor vehicle door lock so on develop that a quick release succeeds, and indeed without the locking lever or central locking lever is necessarily involved.

To solve this problem, the invention proposes a generic motor vehicle door lock before that the lock on the quick release lever to the locking lever connected, with the quick release lever - essentially independent of the position of the locking lever - the locking mechanism in the course of the quick release releases with the help of the drive. In other words, So the locking mechanism is not (anymore) for the most part locking lever designed as a central locking lever connected. Rather, the intermediary ensures Quick release lever as it were for decoupling between locking mechanism and locking lever. This decoupling can now be used with the help of the drive so that the Quick release lever with the locking lever at least in its "locking position" non-positively (and / or form-fitting) is coupled, but otherwise the Lock (in the quick release) releases, namely immediate and practically instantaneous.

Form in the locking position of the locking lever Quick release lever and locking lever, as it were a unit, so that to the quick release lever connected lock reliably the position "locked" occupies. In contrast, the drive gives the quick release lever free once the compulsory control device a command for quick release to the motor Drive sends.

This is done in detail so that the quick release lever as a pivotal to the locking lever connected Einarmhebel is executed. Of the Quick release lever preferably lifts with the help of a Gesperreauslegers a clutch lever to lock the Locks on. This happens when the locking lever the position "locked" occupies and in this "Locking position" non-positively (and / or positively locking) coupled with the quick release lever.

In the course of quick release or unlocking in general However, the respective clutch lever is lowered and the locking mechanism unlocks. This raising and lowering of the Clutch lever has the consequence that a release lever at lifted clutch lever against the pawl of Gesperres performs a no-lift. Is, however, the clutch lever lowered, the release lever can be directly on the Pawl act to open the catch.

The motor drive usually has a Quick release pin, which the quick release lever in the locking position of the locking lever at this applies and for quick release of the locking lever releases. In this quick-release pin it is one on an axle of a driven pulley Front double cams arranged. - In usually already enough pivoting movements of about 5 ° to 90 ° of the double cam to in the course of Quick release release the quick release lever.

The driven pulley is usually with an electric motor Output shaft and worm gear driven and serves primarily - as is well known - for the adjustment of the Locking lever or central locking lever at least in the positions "unlocked" and "locked". Of course, a position can also be "anti-theft" realize this way. To this Purpose has the driven pulley on the back of a or two control pins that fit into a fork recess of the locking lever or central locking lever to its Immerse panning.

Next to the locking lever or central locking lever is still an internal locking lever provided. Both Levers can form a unit. Usually, however provided two different components, which is a common Turn axis and force fit and / or positive fit mesh. This will ensure that the inside lock lever directly on the Central locking lever can act, if, for example the position "unlocked" is desired. That can if necessary in the course of a "double stroke" with the help of a Be implemented inside actuating lever. The first stroke of the Inside operating lever transfers the inside locking lever and thus the cooperating central locking lever in the position "unlocked". The second Hub ensures that the unlocked in this way locking is opened with the help of the release lever.

7 with the rotary catch closed (FIG. 8) or in the "locked" position and open rotary latch (FIG. 9) or in the "unlocked" position, as well as in individual representation (FIG. 10).

In the figures, a motor vehicle door lock is shown, which with a conventional catch from catch 1 and pawl 2 is equipped. In Figs. 1, 2 and 7 and 8, the ratchet 1, 2 is merely indicated while Figs. 4a, 4b show details.

The locking mechanism 1, 2 is composed of a catch 1 and a pawl 2 together. In addition, there is still a release lever 3 is provided, which lifts the pawl 2. However, this only happens when there is a clutch lever 4 in its lowered position according to FIG. 4b or in the solid representation of FIG. 7 is located (unlocked position). Because in this case, one is on a backdrop guided coupling pin 5 also lowered and engages in a recess 6 in the release lever 3 so that the coupling pin 5 during a pivoting movement of the release lever 3 in the direction of the arrow against a stop 7 of Pawl 2 beats, which logically a rotary motion in a clockwise direction, so that the catch 1 spring assisted opens.

However, the clutch lever 4 takes its raised position as shown in FIG. 4a or in accordance with the dot-dash line Representation in Fig. 7 a (locking position), so the coupling pin 5 from the stop 7 the pawl 2 free, so that corresponding opening movements of the release lever 3 in a clockwise direction, that the coupling pin 5 in a recess 8 of the pawl 2 evades. The locking mechanism 1, 2 can in this case so not be opened.

The raised position of the clutch lever 4 (Fig. 4a; dash-dot line in Fig. 7) corresponds to the "locking position" the motor vehicle door lock while the lowered position of the clutch lever 4 (Fig. 4b; pulled through in Fig. 7) the position "unlocked" symbolizes.

To now the clutch lever 4 in the described positions to be able to transfer, a locking lever 9 is provided, which is a central locking lever 9 is. According to the embodiment in FIGS. 7 to 10 However, serves to act on the clutch lever 4 a Interior locking lever 10. Central locking lever 9 and Interior locking levers 10 are both positively locked together and / or positively connected and rotate around a common axis 23.

The central locking lever 9 is using a motor Drive 11, 12, 13, 14 and 14a, 14b pivoted. This motor drive 11, 12, 13, 14 is in Individual from an electric motor 11 and a connected Output shaft with output worm 12, which is in a driven pulley 13 meshing intervenes. The driven pulley 13 is the back in the context of the embodiment with two Control pins 14 a, 14 b equipped in an associated Fork recess 15 of the central locking lever 9 to immerse himself in his panning (see Fig. 5).

Thus, the front control left control pin 14b in the Locking position of FIG. 1 at a rotation of the driven pulley 13 counterclockwise for a Extension 16 of the fork recess 15, in which he dives, also pivoted counterclockwise. This then also applies to the central locking lever 9 in Whole as in the transition from Fig. 1 to Fig. 2 below Consideration of the movement arrows shown clearly becomes.

The rotational movement of the driven pulley 13 is now characterized stopped, that the previously right control pin 14a to Stop surfaces 15a of the fork recess 15 applies. at This transition of the central locking lever 9 of the Position "locked" (Fig. 1) to the position "unlocked" (Fig. 2), the clutch lever 4 lowers from his Position according to FIG. 4a (locked) corresponding to the position of Fig. 4b (unlocked). - In unlocked position According to Fig. 4b is a tailed to the trigger 3 Door outside handle thus able to dig out the pawl 2 and thus the catch 1 and the associated motor vehicle door to open.

For quick release according to FIG. 3, the illustrated Motor vehicle door lock additionally still over a the locking lever or central locking lever 9 associated quick release lever 17, which in Detail is shown in Fig. 6. The locking mechanism is 1, 2 on this quick release lever 17 to the locking lever 9 connected. In this way, the Quick release lever 17, the locking mechanism 1, 2 in the course of Quick release by means of the drive 11, 12, 13, 14 release, essentially independent of the Position of the locking lever or central locking lever 9. Starting from the locking position according to Fig. 1 is the quick release lever 17 with the locking lever 9 at least in the one shown there Functional position "locked" non-positively or positively associated with this. That is, the clutch lever 4 is in the raised position of FIG. 4a.

However, if a quick release is provided, so the clutch lever 4 is lowered immediately, because insofar a Gesperreusleger 18 of the quick release lever 17 performs a corresponding movement. Because the quick release lever 17 and the clutch lever 4 are over the Gesperreausleger 18 connected to each other. Indeed the quick release lever 17 is designed as a Einarmhebel which pivotally in a hinge 19 to the Locking lever 9 is connected.

With the help of the Gesperreauslegers 18 of the clutch lever 4 for locking the locking mechanism 1, 2 raised when the motor vehicle door lock in the whole in the position is "locked". Because in this case takes the central locking lever 9 the position of FIG. 1 and Incidentally, the quick-release lever 17 with the help a Schnellentriegelungszapfens 20 to the central locking lever 9 (non-positive or positive) applied (see. Fig. 1) or even pressed on this.

The quick release pin 20 belongs to the motor Actuator 11, 12, 13, 14 and is more detailed than one Axle 21 of the driven pulley 13 rotatable and front For this purpose arranged double cam 20 is formed. In the course of the quick release performs this double cam 20 a pivoting movement, to an angle α of about 5 ° to 90 °, according to the embodiment about 40 °, corresponds (See the transition from Fig. 1 to Fig. 3).

This pivoting movement is sufficient, so that the quick release lever 17 from its attachment to the central locking lever 9 is released, which in turn in this process (yet) has not been moved (see the movement arrows in Fig. 3). It turns here so a gap S between the quick-release lever 17 and the lock lever 9 on.

The central locking lever 9 is only moved when the control pin 14b in the extension 16 of the fork recess 15 dips and in this way the central locking lever 9 takes along. At the end of the quick release and after sweeping the angle α by the double cam 20 this is not (yet) the case, because the control pin 14b only to bear against a boundary 22nd in the extension 16 has come (see Fig. 3).

In the modified embodiment of FIGS. 7 to 10 are identical components with matching reference numerals Mistake. To transfer the clutch lever 4 of the in Fig. 7 shown by the position "unlocked" in the dot-dashed position "locked" is a Gesperreusleger 24 on the inside lock lever 10 (see Fig. 8). Next to the inside locking lever 10 and the central locking lever 9 is still a lock cylinder lock lever 25, which is to a not shown Lock cylinder is connected (see Fig. 8 to 10).

With the help of an internal operating lever 26 can be Lock 1, 2 open, namely by this inside lever 26 corresponding to the double arrow in Fig. 7 is moved and in the same direction of rotation on the release lever 3 operates as shown in FIGS. 4a, 4b. That succeeds however only when the clutch lever 4 in the pulled through position shown "unlocked" is located. takes the clutch lever 4, however, the upper (dash-dotted lines indicated) position "locked" in Fig. 7, so the internal operating lever 13 is no longer able to to open the locking mechanism 1, 2. - If the application of the Clutch lever 4 with the inner locking lever 10 (or the central lock lever 9 or the lock cylinder lock lever 25 is removed, so takes the clutch lever 4 spring assisted in Fig. 7 shown pulled through Position "unlocked", so that the actuating lever 13 now able to open the ratchet 1, 2.

In the context of the embodiment of FIGS. 7 to 10 is still a locking lever 27 realized, which with the Rotary latch 1, a structural unit 1, 27 forms. To do this, grab one Nose 28 on the locking lever 27 and a groove 29 in the rotary latch. 1 into each other (see Fig. 8).

The locking lever 27 is designed as a two-armed lever and has via a blocking arm 27a and a sensing arm 27b. In the exemplary embodiment, the interrogation arm 27b carries a Magnets M, the position of a housing-mounted Hall sensor as a detection device D is queried (see. Fig. 8).

The blocking arm 27a or the locking lever 27 as a whole provides that the central locking lever 9 when open Rotary latch 1 is blocked. This position is in FIG. 9 and in solid line in Fig. 7 before. Care here the blocking arm 27a of the locking lever 27 for a Nose 30 on the central locking lever 9 mentioned Blockade experiences. In this way, the central locking lever 9 in the position "unlocked" after the Fig. 9 held. This happens - as I said - only when the catch is open 1. The same position is like said in Fig. 7 shown in solid.

In this case, they perform in detail in FIG. 10 shown remaining locking lever 10, 25, namely the Interior lock lever 10 and the lock cylinder lock lever 25 one empty stroke each. All locking levers 9, 10 and 25 are co-ordinated on the common axis 23 stored. To connect between the Central locking lever 9 and the other locking levers 10, 25 is a spring or coil spring 31st realized. The coil spring 31 is also on the axis 23 stored and ensures the desired idle stroke.

With reference to FIG. 10 it can be seen that the spiral spring 31 has two spring ends 31a and 31b, each at abut a web 32 of the central locking lever 9 or include this bridge 32 between them. In the thus created space dive another Bridge 33 of the lock cylinder lock lever and a bridge 34 of the inner locking lever 10 a.

Now if the central locking lever 9 in the position blocked according to FIG. 9, because its nose 30 am Blockade arm 27a of the locking lever 27 is present, so lead Pivoting movements of both the internal locking lever 10th as well as the lock cylinder lock lever 25 - individually or jointly - in each case that their respective Webs 33, 34 deflect the left spring arm 31a of the spring 31 (see Fig. 10).

The central locking lever 9 thereby changes its position However not. After the deflection, the up this way compressed coil spring 31 for both the inside lock lever 10 as well as the lock cylinder lock lever 25 again her original To take position. So there is an idle stroke.

The entire locking lever system 9, 10, 25 remains while in the unlocked position, with open Rotary latch 1, because the central locking lever 9 his Retains position of FIG. 9. The clutch lever 4 can in this case his dot-dashed line position "locked" only temporarily occupy, so returns for example after completion of his admission by the Interior lock lever 10 or the lock cylinder lock lever 25 back to the "unlocked" position back. This is consequently his permanent function in this context. Only the central locking lever 9 So is able to constantly clutch lever 4 in the Functional position "locked" to convict, like this has already been explained in the beginning. But that only works when the catch 1 is closed and consequently the Lock lever 27 releases the central locking lever 9.

However, as long as the central locking lever 9 and thus the remaining locking levers 10, 25 their permanent functional position "unlocked" by the blockade with the help of Take locking lever 27 and while open catch, For example, the operating lever or inner operating lever 13 have no effect, so also goes empty.

However, if the catch 1 is closed, then the locking lever takes 27 the position shown in Fig. 8, as they also shown in dashed lines in Fig. 7. This turns a space 35 at the point, which is open when the catch according to FIG. 7 previously from the blocking arm 27a has been taken.

The space 35 now allows unhindered movements of the Central locking lever 9, because his nose 30 at the Blockade arm 27a can pass. This results in that with closed catch 1, the entire locking lever system 9, 10, 25 both the positions "locked" as well as "unlocked" is able to take. As well the clutch lever 4 is capable of both positions according to FIG. 7 to take permanently.

Consequently, (only) with closed catch 1 a Locking take place to the top dot-dashed Position of the clutch lever 4 and thus an idle stroke of the Inside operating lever 13 corresponds. At the same time the clutch lever 4 but also pulled in Fig. 7 Cover shown position ("unlocked"), so that the operating lever 13 is able to open the locking mechanism 1, 2.
