Description

Auxiliary closing drive

The invention relates to a Schiießhiifsantrieb with the features of the preamble of claim 1, a Verschlusseiement arrangement with the features of the preamble of claim 13 and a method for assembling a Schiießhilfsantriebs with the features of the preamble of claim 14.

The known auxiliary closing drive (DE 10 2016 103 647 A1), from which the invention proceeds, is associated with a motor vehicle lock. Here it serves for the motoric adjustment of the latch of the motor vehicle lock from a prefastening division into a main closing division. In the present case, all types of door, hood, lid or flap locks are summarized under the term "Kraftfahrzeugschioss". To generate drive movements of the known Schiießhiifsantrieb with a motor drive and with a drive downstream feed gear, here a spindle gear for generating linear drive movements, equipped. Furthermore, the Schiießhiifsantrieb a drive housing, which has a first drive housing part and a second drive housing part connected thereto, wherein the first drive housing part forms a receiving space for a portion of the drive and a portion of the feed gear. After the drive and the feed gear have been inserted into the first drive housing part or in its receiving space, the second drive housing part is placed on the first drive housing part, thus forming the substantially closed drive housing. The unit of drive, feed gear and drive housing preassembled in this way is subsequently mounted in a separate subsequent assembly step on a structural component of the closure element of the closure element arrangement, for example on a structural component of a motor vehicle door. The assembly is relatively complex and therefore correspondingly time and cost intensive.

The invention is based on the problem of simplifying the installation of the known auxiliary closing drive. The above problem is solved in a closing auxiliary drive according to the preamble of claim 1 by the features of the characterizing part of claim 1. By the first drive housing part is part of a module carrier and thus a structural component of a closure element assembly, such as a motor vehicle door assembly, it is no longer necessary to first preassemble a unit of drive, feed gear and these receiving Antriebsge- housing parts and then in a separate step with the corresponding Structural component of the closure element, for example, the motor vehicle door to connect. Rather, eliminates by the proposed solution, the step of mounting the drive housing to the corresponding structural component, since the first drive housing part is already part of the structural component, namely the module carrier is.

The proposed teaching thus makes it possible by the integration of one of the drive housing parts in the module carrier a simplified installation, since the number of items of the auxiliary closing drive and its attachments and accordingly the assembly time and manufacturing costs can be reduced.

In the embodiment according to claim 2, the first drive housing part is designed in one piece with the module carrier, whereby the assembly costs can be further reduced.

The preferred embodiment according to claim 3 defines a module carrier which can carry components of further functional components of the closure element arrangement, for example the motor vehicle door arrangement. The proposed closing auxiliary drive then serves as a carrier for the respective further functional component, which simplifies the assembly of a closure element arrangement as a whole. In the development of the invention according to claim 4, the module carrier and / or the first drive housing part is part of a wet room / dry space separation. Such serves to separate a wet room in the door interior of a drying room. Preference is given to that of the first Drive housing part formed receiving space to the wet space through the first drive housing part or a housing bottom of the first drive housing part separately. Drive and feed gear are thus arranged dry room side. On this page is then the receiving space through the second Antriebsgehäuseteii that then forms a lid, closed.

In claims 5 to 7 preferred embodiments of the drive housing are described. According to claim 7, it is conceivable that the receiving space is covered watertight by the second drive housing part, which makes it possible to arrange the drive and feed gear also on the wet-room side. In principle, however, it is preferred if the drive and feed gear are arranged on the dry-room side, whereby a costly seal between the first drive housing and the second drive housing can be dispensed with.

The claims 8 to 10 define preferred embodiments of the first drive housing part and / or the second drive housing part. In particular, the first Antriebsgehäuseteii serves significantly the storage of the drive and / or feed gear. But also the second drive housing part, which in particular forms a cover, can be provided for mounting the drive and / or feed gear.

According to the preferred embodiment according to claim 11 is in the feed gear to a spindle gear with the spindle gear elements spindle and spindle nut. In this case, the T rennebene between the first Antriebsgehäuseteii and second Antriebsgehäuseteii, ie the plane in which the two drive housing parts in the assembled state, preferably substantially parallel to the spindle axis of the spindle and / or to the drive shaft of the motor drive (axis of the motor shaft) , In particular, the mounting direction in which the first Antriebsgehäuseteii and the second Antriebsgehäuseteii are merged during assembly, orthogonal to the spindle axis and / or drive axle. By such an arrangement, the space within a closure element or a motor vehicle door is particularly well utilized. In the embodiment according to claim 12 runs on the Schließhilfsan- drive backward power flow between the drive and feed gear, so a traction, which occurs during operation of the Schiießhilfsantriebs between the drive and feed gear, on the first drive housing part. The second drive housing part, in particular if this is ausgebiidet must accordingly only a small proportion of the power flow or preferably no power transfer at all and can be designed to be correspondingly thin and material-saving. According to a further teaching according to claim 13, which has independent significance, a closure element arrangement, in particular a motor vehicle door arrangement, is claimed as such with a proposed auxiliary closing drive. Reference may be made to all versions of the proposed auxiliary closing drive.

According to another teaching according to claim 14, which also has independent significance, a method for assembling the Schiießhilfsantriebs is claimed. Essential for the proposed method is that in a pre-assembly step provided with the first drive housing part module carrier on a closure element, for example on a motor vehicle door, is pre-assembled and only then the second drive housing part, which forms a particular lid, is mounted on the first drive housing part. Thereby, what is claimed in the embodiment according to claim 15, the components "drive" and "feed gear" already assembled and fully tested for their function before the second drive housing part completely closes the receiving space. In the following the invention will be explained in more detail with reference to a drawing showing only one exemplary embodiment. In the drawing shows

1 shows a proposed closure element arrangement with a proposed closing auxiliary drive, Fig. 2 shows the proposed closure element arrangement of FIG. 1 in a section according to view II of FIG. 1 and

Fig. 3 in a) a side view of the detail lilb of Fig. 2, wherein the 5 Schiießhilfsantrieb is shown with the drive housing open, and in b) a section according to view b in Fig. 3a.

Fig. 1 shows schematically a proposed closure element assembly 1, which is designed here as a motor vehicle door assembly, with a Verklele element opening 2 in the form of a motor vehicle door opening and with a closure element 3 in the form of a motor vehicle door. The motor vehicle door assembly 1 is a motor vehicle lock 4 and a proposed Schiießhilfsantrieb 5 assigned. The Schiießhilfsantrieb 5 can be arranged for example in the wet room 6 or in the drying room 7 of the vehicle door 3. As already indicated, the term "motor vehicle lock" encompasses all types of door, hood, lid or flap locks. Accordingly, it can be in the closure element 3 not only to a motor vehicle door, but also to a hood, a ceiling! or a flap of a motor vehicle act.

20

The proposed Schiießhilfsantrieb 5 is associated with the motor vehicle lock 4 and is preferably the transfer of the motor vehicle lock 4 from a Vorschließzustand in a main closing state.

In Fig 1, the structure of the motor vehicle lock 4 with the usual closing elements lock latch 4a and pawl 4b is shown, wherein the lock latch 4a cooperates in a likewise conventional manner with a closing wedge 4c or the like. Instead of the closing wedge 4c may also be a locking pin, a striker or the like. Be provided.

30

Here and preferably, the auxiliary shooting drive 5 is configured and arranged separately from the motor vehicle lock 4. The Schiießhilfsantrieb 5 acts by means of a, in particular flexible, transmission means 8, preferably a Bowden cable, as part of a Schließhilfsvorgangs on the Kraftfahrzeug¬

35 included 4, in particular the Schiossfaile 4a, a. The auxiliary closing drive 5 has, as shown in Figures 2 and 3, a motor drive 9, a drive 9 downstream feed gear 10 for generating drive movements and a drive housing 11 for receiving the drive 9 and the feed gear 10. The drive movements are transmitted via the transmission means 8 to the motor vehicle Schioss 4. The drive housing 11 in turn comprises a first drive housing part 11a and a second drive housing part 11b, wherein the first drive housing part 11a forms a receiving space 12 for at least a portion of the drive 9 and at least a portion of the feed gear 10.

The feed gear 10 has here and preferably a spindle gear 13 with the spindle gear elements spindle 13a and spindle nut 13b. It converts the rotational movement of the drive 9 into a linear drive movement. Here, the spindle nut 13b has an external toothing, in which more a worm wheel 9a of the drive 9 engages the spindle drive 13 for driving force transmission. As a further component, the feed gear 10 has a coupling element 10a, via which the spindle 13a is coupled to the transmission means 8. The drive housing 11 is preferably made of plastic and has, for example, in this embodiment, in addition to said first drive housing part 11a and second drive housing part 11b no further drive housing parts. In other words, the interior of the drive housing 11 relative to the surroundings of the auxiliary closing drive 5 is substantially closed here solely by the first drive housing part 11a and the second drive housing part 11b. The receiving space 12 corresponds here essentially to the housing interior, since the second Antriebsgehäuseteii 11b is designed here as a flat lid, which provides no additional storage volume. In principle, however, it would also be conceivable for the second drive housing part 11 b to form a further receiving space, similar to the first drive housing part 11 a, in which case the housing interior would then be formed by the two receiving spaces in the mounted state.

It is essential in the case of the proposed auxiliary closing drive 5 that the first drive housing section 11a is provided by a module carrier 14 assigned to the lock or motor vehicle door arrangement 1 is, the first drive housing part 11a so part of the module carrier 14 is. Here and preferably, the first drive housing part 11a is integrally formed with the module carrier 14, that is, formed as a one-piece plastic part. The module carrier 14 is a structural component of the motor vehicle door and forms at least one section, in particular the largest part, of a wet room / drying space separation 15, which separates the wet space 6 from the drying room 7 in the interior of the door. Since in this case the first drive housing part 11a is already part of the module carrier 14, the drive housing 11 does not have to be connected to the module carrier 14 in a separate assembly step. Only the second drive housing part 11b forming the cover still has to be mounted on the first drive housing part 11a. The assembly of a proposed Schiießhiifsantriebs 5 and according to a proposed closure element assembly 1 is thereby significantly simplified compared to the prior art.

As shown in Fig. 2, is in the Ausführungsbeispie described here! the first drive housing part 11a and the housing bottom are offset relative to the rest of the module carrier 14. The offset is provided here to the wet room 6 back. The second drive housing part 11b is arranged in the dry space 7 in this case. In principle, however, the reverse case is also conceivable, namely that the first drive housing part 11a or its housing bottom is offset from the drying space 7 and the second drive housing 11b is arranged in the wet space 6. Especially in the latter case, it is preferred if the housing interior or receiving space 12 is watertight with respect to the surroundings and / or with respect to the wet space 6, for which purpose a corresponding seal between the first drive housing part 11a and the second drive housing part 11b would be particularly preferred. The housing interior or receiving space 12 would then be covered by the second drive housing part 11b in particular in a watertight manner. In the exemplary embodiment selected here, however, the latter is not necessary since the first drive housing part 11a already separates the wet space 6 from the drying space 7 and thus the receiving space 12 is necessarily located in the area of the drying space 7. Preferably, only the bushing in the first drive housing part 11a for the transmission means 8 has to be sealed watertight. In order to directly connect the second drive housing part 11b to the first drive housing part 11a, the first drive housing part 11a and the second drive housing part 11b here and preferably have interacting, snap-fitting elements 16a, 16b. By way of example, these are hooks 16b on one of the drive housing parts 11a, 11b and corresponding depressions 16a on the respectively other of the drive housing parts 11a, 11b. It is also conceivable to provide a screw connection enabling elements (not shown), for example, holes one of the drive housing parts 11a, 11b and holes, in particular tapped holes in the other of the drive housing parts 11a, 11b, whereby the second drive housing part 11b screwed to the first drive housing part 11a could.

As shown in FIGS. 3 a and b, here and preferably the first drive housing part 11 a and the second drive housing part 11 b are each configured to mount the drive 9 and / or the feed gear 10. In this case, the first drive housing part 11a is designed so that the unit consisting of the drive 9 and feed gear 10 is arranged and stored completely inside the receiving space 12. The second drive housing part 11 b comes in the mounted state at least with the drive 9 in contact, but may in principle also be designed so that it also comes into contact with the feed gear 10. It is further provided that the first drive housing part 11a and / or the second drive housing part 11b may comprise a damping material 17, in particular a rubber-like damping material 17. This allows damping of vibrations in particular between the drive 9 and / or feed gear 10 on the one hand and the drive housing part 11a or 11b on the other hand. The damping material 17 is preferably formed on the remaining part of the drive housing part 11 a and 11 b, in particular molded. The respective drive housing part 11a or 11b thus has a two-component structure, that is, has a particularly harder outer structure and a different, in particular softer and more elastic internal structure.

As can be seen in particular in FIGS. 3 a and b, the parting plane E between the first drive housing part 11 a and the second drive housing part 11 b runs essentially parallel to the spindle axis X 1 and also to the drive axis x _2. Additionally or alternatively, it is provided that the mounting direction R, in which the first drive housing part 11a is merged with the second drive housing part 11b during assembly, orthogonal to the spindle axis Xi and drive axis X ₂ extends. Here and preferably, both axes Xi, X ₂ extend substantially parallel to the module carrier 14, moreover.

As can be seen in particular in FIG. 3b, the first drive housing part 11a is provided with a larger wall thickness than the second drive housing part 11b. The reason for this is that in the exemplary embodiment shown here, a force flow going back on the auxiliary closing drive 5 between the drive 9 and the feed gear 10 predominantly extends over the first drive housing part 11a. The second drive housing part 11b receives here and preferably less to no forces. As described above, the proposed closure element arrangement 1 has a motor vehicle door as the closure element 3 and a motor vehicle lock 4 for the closure element 3 and a Schließhilfsan- drive 5 for the motor vehicle lock 4. The Schiießhilfsantrieb 5 is ausgebiidet as explained above. It is essential that the first drive housing part 11a is provided by a module carrier 14 assigned to the Verschiusselementanordnung 1 and in particular is integrally formed therewith.

As shown in FIG. 2, the module carrier 14 can be fixed to the closure element or the motor vehicle door 3. In a preferred embodiment, the module carrier 14 carries the motor vehicle lock 4 and / or a window guide rail and / or a part of an outside door handle 18. In the illustrated and also preferred embodiments, the module carrier 14 carries part of a door inner handle 19 and / or a window lifter 20th

In the proposed method, the module carrier 14 provided with the first drive housing part 11a is preassembled on the closure element 3 of the closure element arrangement 1 in a pre-assembly step, the second drive housing part 11b being mounted on the first drive housing part 11a only in a subsequent assembly step. When the two drive housing parts 11a, 11b are connected to each other, it is preferable that both Drive 9 and the feed gear 10 already inside the housing and arranged in particular in the receiving space 12. In the proposed method, prior to the assembly step, which connects the first drive housing part 11a to the second drive housing part 11b, a complete mechanical and electrical functional test of the closing auxiliary drive 5, which is otherwise completely assembled, is particularly preferred.
