Description

MOTOR VEHICLE DOOR CLOSURE AND METHOD FOR ASSEMBLING A MOTOR VEHICLE DOOR CLOSURE

The invention relates to a motor vehicle door lock, comprising a housing, further comprising a locking mechanism, and a functional lever mechanism for (internally) actuating and / or locking the locking mechanism, wherein the functional lever mechanism has at least one first and one interacting second functional lever, which together form a mounting assembly form. The housing is usually composed of a lock case and a lock cover or plastic lid. In the lock case, the locking mechanism is essentially composed of a catch and a pawl. In contrast, the functional lever mechanism is mainly stored in the plastic lid. The plastic lid is connected to the lock case in order to realize a close to an inlet mouth for a locking pin tight housing, which protects the elements therein from environmental influences.

As usual, the locking mechanism interacts with the previously mentioned locking bolt, which moves into the inlet mouth and interacts with the rotary latch. For this purpose, an associated motor vehicle door lock is mounted in or on a corresponding motor vehicle door, whereas the locking bolt undergoes an arrangement mostly on the body side. As a rule, a B or C pillar is available for this purpose. As is conventional, the motor vehicle door lock and the locking bolt taken together define the motor vehicle door lock.

In principle, the procedure can also be reversed. In this case, the motor vehicle door lock is provided on the body side, whereas the locking pin is connected to the associated motor vehicle door. For example, the procedure is with tailgates. In the prior art according to DE 39 02 776 A1, a functional lever mechanism is realized, which, for example, has an external operating lever, which operates on a release lever, which in turn acts on the pawl. Between the outside actuating lever and the release lever, a clutch lever is arranged. In addition, an internal locking lever and an anti-theft lever and an internal operating lever are provided, all of which belong to the functional lever mechanism.

In the generic state of the art according to DE 103 20 448 A1, the actuating lever is equipped with a first part lever and a second part lever in a motor vehicle door lock. In addition, there is a coupling element which is controlled by a locking lever and thereby selectively connects the two partial lever with each other. One partial lever is designed as an internal operating handle lever and the other partial lever as an internal actuating trigger lever.

The state of the art has proven itself in principle, but reaches its limits when it comes to the assembly of the assembly assembly from the first and second functional lever. This can basically be attributed to two circumstances. First of all, the one or the two function levers must be connected to the other and possibly even outside the motor vehicle door lock located further lever and control elements. Depending on the type of vehicle and installation location, different positions of the relevant functional lever result. In addition, the installation conditions for the mounting assembly inside the housing are often less easy to assemble and the mounting assembly is, for example, in a hard to reach area of the housing concerned. To overcome these difficulties, the prior art has no convincing solutions to offer.

Consequently, the present invention is based on the technical problem of further developing such a motor vehicle door lock so that a simple adaptation of the mounting assembly to the respective installation situation is made possible and even complicated housing shapes and, in particular, areas that are difficult to access can be controlled. To solve this technical problem, the invention proposes in a generic motor vehicle door lock that both levers are mounted on a fixable in or on the housing and its axis of rotation defining hollow axle body.

Due to the fact that the axle body is hollow, it is advantageously possible to connect the axle body to the housing by means of a mandrel passing through the axle body. As a result, the mandrel in question typically acts as a bearing pin for the axle body, which consequently can pivot relative to the mandrel in question. In this case, both function levers may be rotatably connected to the axle body. Since the axle body is rotatably mounted on the mandrel, in this way both function levers are synchronously pivoted together with the axle body. In principle, however, it is also possible that the two levers relative to the hollow axle body - can be pivoted - in addition or alternatively.

In the former case, the pivotable operating lever on the axle body of the hollow axle body acts as a further bearing pin, in addition to the axle body sweeping mandrel. The latter variant corresponds to the fact that the axle body with the mandrel, for example, is rotatably connected and the two function levers - only - can be pivoted on and opposite the hollow axle body. All three variants are possible in principle.

As a rule, however, the procedure is such that the two function levers on the hollow axle body are initially fixed (rotationally fixed). This pre-assembly takes into account the subsequent installation situation of the assembly assembly and their subsequent connection to existing or yet to be mounted other elements. The determination of the two function lever on the hollow axle body can be carried out so that both functional levers are rotatably connected to the axle body. Of course, it is also possible that only one of the two function levers is rotatably coupled to the axle body, whereas the other further function lever can perform pivotal movements relative to the axle body and the first function lever rigidly connected thereto. In any case, the assembly assembly of the two function levers and the hollow axle body according to the invention is connected to the housing. For this purpose, the already mentioned mandrel passes through the hollow axle body. For this purpose, the mandrel may be equipped with a thickening at one end. With the help of the thickening, the mandrel is supported on a housing wall. The opposite end of the dome is in contrast connected to the opposite housing wall. Consequently, the mandrel passes through the entire housing in the region of its attachment. In this case, the thickening opposite end of the dome may be connected to the housing wall by plastic deformation of the dome, for example be caulked to the housing. As a rule, however, the procedure here is that the thickening opposite end of the dome is connected by means of a securing element, such as a retaining ring with the associated housing wall. The mandrel and the securing element together form a securing means for the axle body.

Consequently, the installation of the assembly assembly according to the invention also succeeds and in particular in hard to reach areas of the housing. For this purpose, it is according to the invention only necessary to place the previously discussed assembly assembly between the two opposite housing walls and then pass the mandrel through the hollow axle body and set at the opposite side of the thickening of the dome housing wall. The mounting assembly is thus fixed as a unit in or on the housing. According to a further advantageous embodiment, the axle body is a rotationally symmetrical hollow body. Mostly at this point a metallic axle body is used, because the two function levers are typically also formed as a metal stampings. In principle, however, it is also possible to work with plastic levers and of course also a hollow axle body made of plastic.

It has proven itself overall, when the hollow body is designed as Hohizylinderachskorper. The Hohizylinderachskorper in question has different areas that serve the different purposes and advantageously correspond to different outer diameters of Hohizylinderachskorpers. Thus, the hollow axle body or the Hohizylinderachskorper advantageously realized at this point may be equipped on the one hand with a storage area for the function lever and on the other hand a receiving area for further functional elements. By way of example, these further functional elements can be a spring biasing the functional levers or the entire assembly assembly, which may be designed as a helical coil spring and, in the simplest case, fitted onto the receiving region.

So that the two function levers are axially secured on the hollow axle body, a securing body is provided in addition to the axle body. This ensures the axial securing of the two levers on the axle body. In this case, the fuse body in question may interact with one or more stops on the hollow axle body.

According to an advantageous embodiment, the securing body is a socket that can be detachably connected to the axle body. Moreover, it has proven useful if the securing body and the axle body are locked to one another in a defined axial position relative to one another. As a result, the detent can also be canceled, so that the position and mutual alignment of the two function levers changed as needed can be. In addition, the detent allows that from the outset the two function levers according to the invention in virtually any angular position can be fixed to each other on the axle body, so that can be realized and implemented with the described assembly assembly virtually all conceivable installation and Anbin- situations. This enormously increases the flexibility of the mounting assembly. - The invention is also a method for mounting a motor vehicle door lock, as described in more detail in the current claim 10. As a result, a motor vehicle door lock is provided, which is equipped with a mounting assembly of (at least) two functional levers which are mounted together on a hollow axle body defining its axis of rotation. As a rule, both function levers have a common axis of rotation. Since the axle body is advantageously designed as a rotationally symmetrical hollow body, the common axis of rotation of the two functional levers typically coincides with the axis of rotational symmetry of the hollow body in question and fixes the rotational axis of symmetry of the relevant axis of rotation. The two function levers can be mounted in virtually any angular orientation to each other on the axle body in question. This is ensured by the fuse body. For this is a releasably connected to the axle body bush, which is locked to each other with the axle body in a defined axial position. As a result, a special flexibility of the two function levers is provided, which can be adapted to virtually any conceivable installation and connection situation. D. h., The two function lever can be aligned on the hollow axle body in the context of the invention, for example, in overlap with each other, in 90 ° -Winkelstellung, 180 ° -Winkel- position, etc. and fixed on the hollow axle body. Of course, any other angular positions are possible and are encompassed by the invention. In addition to the particular flexibility of the assembly assembly according to the invention this convinces by a simple and intuitive installation. This is especially true for hard to reach areas of the housing. In fact, it is sufficient to mount the assembly assembly between two housing walls and fix it with the help of a mandrel engaging the axle body and the two housing walls. The mandrel has at its one end over a thickening as it were stop, while its other opposite end is connected to the associated housing wall. This can be fixed or solvable. In the former case, it is conceivable to plastically deform the mandrel at the respective end. The housing wall can also be plastically deformed to fix the dome. A releasable fixation of the dome is conceivable if the thickening opposite end of the dome by means of a securing element, for example a retaining ring on the associated housing wall (releasably) is set.

In any case, the determination and installation of the mounting assembly according to the invention succeed easily and quickly, even in inaccessible housing areas. In addition, since the levers can still be pivoted and aligned with each other - even when the assembly module is installed - this explains why special variability is achieved with a simple design at the same time. Here are the main benefits.

In the following the invention will be explained in more detail with reference to a drawing showing only one exemplary embodiment; show it:

Fig. 1 shows the motor vehicle door lock according to the invention in an overview, reduced to the components essential for the invention, Fig. 2 is a perspective detail of Fig. 1 in the region of the mounting assembly and 3 shows a longitudinal section through the mounting assembly according to FIG. 2.

In the figures, a motor vehicle door lock is shown, which is composed as usual of a motor vehicle lock 1 and a closing bolt 2 interacting therewith. The motor vehicle door lock 1 or the motor vehicle door lock as a whole has a housing 3, of which only the so-called plastic cover 3 or lock cover can be seen in the exemplary embodiment according to FIG. For in Fig. 1, the housing 3 is shown with removed lock case.

1, in particular, a locking mechanism 4, 5, which is composed essentially of a rotary latch 4 and a pawl 5 and is stored in the removed lock case. In addition, a functional lever mechanism 6, 7 is still realized. The functional lever mechanism 6, 7 is mounted in the exemplary embodiment on the housing 3 and the plastic cover 3, as will be explained in more detail below. In fact, it can be seen from the longitudinal sectional illustration in FIG. 3 that the functional lever mechanism or the two function levers 6, 7 are arranged and mounted between two housing walls 3a, 3b of the housing 3 lying opposite one another. The two functional levers 6, 7 of the functional lever mechanism 6, 7 are in the exemplary embodiment a first inner actuating lever 6 and a second inner actuating lever 7. This is of course not mandatory.

Because as a function lever 6, 7 are considered in general and within the scope of the invention, any lever which serve to actuate and / or locking the locking mechanism 4, 5 and are suitable. In other words, a release lever, locking lever, external actuating lever, etc., may also be part of the functional lever mechanism 6, 7, which in the exemplary embodiment and for the following considerations is limited to the two inner actuating levers 6, 7. The two function levers 6.7 taken together form a mounting assembly 6, 7, 8, 9, as they are taken together best seen in Fig. 3. In fact, in the context of the invention, the assembly assembly 6 to 9 is initially composed of the two functional levers 6, 7 and an axle body 8. On the basis of a comparative examination of FIGS. 2 and 3, it can be seen that the axle body 8 is hollow and, in the exemplary embodiment, in the form of a spout made of metal and / or plastic. The spout has different areas and different outside diameters. In addition, the mounting assembly 6 to 9 is still a fuse body 9. With the help of the fuse body 9, the two levers 6, 7 are secured axially on the axle 8. For this purpose, the fuse body 9 is formed as a releasably connectable to the axle 8 socket 9. In fact, the fuse body or the bushing 9 and the axle body 8 in mutually defined and shown in FIG. 3 axial position mutually lock each other. For this purpose, a latching connection 12 between the fuse body 9 and the axle 8 is provided, which may consist of a circumferential annular groove in the axle 8 and engaging in the annular circumferential groove in the interior of the hollow cylindrical sleeve 9 formed. In principle, the procedure can also be reversed by the sleeve 9 is equipped with the recess and the axle 8 with the locking lug. Of course, other locking connections 12 are conceivable within the scope of the invention and include thereof.

It can be seen that the axle body 8 is designed as a rotationally symmetrical hollow body 8 in the exemplary embodiment. For this purpose, the axle body or rotationally symmetrical hollow body 8 has a rotational symmetry axis 13. The rotational symmetry axis 1 3 at the same time defines the common axis of rotation of the two functional levers 6, 7. The rotationally symmetrical hollow body 8 is a hollow cylindrical axis body 8.

To fix the mounting assembly 6 to 9 on the housing 3, a securing means 10, 1 1 is provided. The securing means 10, 1 1 consists of your the axle body 8 by cross-thorn 10 and a fuse element 1 1 together, in which it is a locking ring 1 1 in the embodiment. In fact, the mandrel 10 passes through the axle body 8 and also the two previously discussed housing walls 3a, 3b, which for this purpose have mutually aligned bores or openings which coincide with the hollow bore of the axle 8 and also the corresponding hollow bore in the socket. 9 be brought to cover. A provided at the right end of the mandrel 10 thickening or a stop flange 14 ensures that the mandrel 10 is fixed axially.

At the stop flange or the thickening 14 opposite end of the mandrel 10 6 and 9 of the mounting ring 1 1 is determined after installation of the mounting assembly. In this way, the mounting assembly 6 to 9 between the two housing walls 3a, 3b aligned and fixed. This is true even if, as in the embodiment, the housing 3 in the region of the two housing walls 3a, 3b otherwise designed to be difficult to access. The pre-assembly of the assembly assembly 6 to 9 is carried out such that initially the first inner operating lever 6 is attached to a stop 15 on the axle body or the Hohlzylinderachskörper 8. Subsequently, the second inner operating lever 7 is mounted on the axle body 8 by plugging. This process can be supported by foot mounts in the form of hoppers and / or grooves, not shown. Both internal actuating lever 6, 7 are then fixed axially by means of the bush 9. For this purpose, designed as a hollow bushing with opening socket 9 via the latching connection 12 with the axle body in question 8 releasably locked. Now the assembly module 6 to 9 is available for installation in the housing.

In this position or in the course of pre-assembly, the two function levers 6, 7 can be aligned with each other in the embodiment, as indicated in FIG. 2. In fact, for example, an angle between the two function levers 6, 7 can be changed. For in the exemplary embodiment, both function levers 6, 7, although secured axially on the axle body 8 with the aid of the bush 9, can nevertheless be pivoted against one another on the axle body 8, for example against resistance. As a result, the two function levers 6, 7 can be easily adapted to various installation positions or can be flexibly connected to the other elements to their connection. 2 it can be seen that the two function levers 6, 7 are coupled together in the exemplary embodiment and not restrictive by a merely indicated clutch lever 16. This clutch lever 16 can, for example, in a the two function levers 6, 7 mechanically interconnected position "engaged or unlocked" and also in a the two function lever 6, 7 not mechanically interconnected position "disengaged or locked" are transferred. This may provide an unillustrated locking drive.

In any case, the coupling lever 16 in question is mounted in the embodiment on the second inner actuating lever 7. In addition, a coil spring 17 shown only in FIG. 1 may be mounted on the axle 8. For this purpose, the axle body 8 is roughly divided in the axial direction into a bearing area 8a for the two function levers 6, 7 on the one hand and a receiving area 8b for further elements, for example the helical spring 17 in the example case. With the aid of the helical spring 17, the entire mounting assembly 6 to 9 may be spring loaded with respect to the housing 3 (see Fig. 3). It can be seen that the axle body 8 is formed with different diameters on the one hand in the bearing area 8a and on the other hand in the receiving area 8b. In addition, the axle body 8 has the previously mentioned flange 15 as a stop for the first functional lever 6. In addition, a further flange 18 may be realized for the second functional lever 7, which also acts as a bearing bush for the first functional lever 6.
