Definitions

  • the present invention relates to an auxiliary locking drive for the motorized adjustment of a latch of a motor vehicle lock according to the preamble of claim 1, a motor vehicle lock arrangement with a motor vehicle lock and such an auxiliary closing drive according to claim 15 and a method for assembling such a motor vehicle lock arrangement according to claim 16.
  • the auxiliary locking drive in question is used in the context of increasing the comfort of motor vehicles.
  • the function of the auxiliary locking drive is the motorized adjustment of a lock latch of a motor vehicle from a pre-locking position to a main locking position as part of an auxiliary locking process.
  • the user When closing a motor vehicle door assigned to the motor vehicle lock, the user only has to ensure that the motor vehicle lock reaches the pre-locking position.
  • the force-intensive closing of the motor vehicle door against the high door seal counterpressures is then taken over by the auxiliary locking drive, which, as mentioned above, moves the latch of the motor vehicle lock from the pre-locking division into the main locking position.
  • the well-known auxiliary closing drive ( DE 10 2013 108 718 A1 ), from which the invention is based, shows a drive housing with a housing interior and in the housing interior a drive motor and an actuating element connected downstream of the drive motor, which can be driven via a motor arrangement.
  • the known auxiliary locking drive is an external auxiliary locking drive which is drive-coupled to the motor vehicle lock, in particular the latch of the motor vehicle lock, via a Bowden cable.
  • the actuating element can be coupled with the Bowden cable in terms of drive technology.
  • the adjusting element is equipped with a corresponding core receptacle into which the spherical core end piece of the Bowden cable core is suspended.
  • the core end piece is hung into the core receptacle when the drive housing is open.
  • the drive housing is then closed so that the drive engagement between the actuating element and the core end piece is fixed.
  • auxiliary closing drive is the fact that the manufacturing process is not very flexible, particularly with regard to the final assembly of the auxiliary closing drive in the motor vehicle.
  • the fixed assignment between the auxiliary closing drive and Bowden cable does not, for example, allow the auxiliary closing drive to be used flexibly on site in production for variants with different Bowden cable lengths.
  • the auxiliary closing drive must always be transported together with the Bowden cable that is already connected, which is comparatively expensive.
  • the invention is based on the problem of designing and developing the known auxiliary closing drive in such a way that the flexibility in the final assembly of the auxiliary closing drive in the motor vehicle is increased.
  • the closed drive housing have a Bowden cable opening for threading the Bowden cable core in one threading movement.
  • the auxiliary closing drive has a guide device for the Bowden cable core, including the core end piece, which guides the core end piece into positive drive engagement with the core receptacle of the actuating element located in the interior of the housing during the threading movement.
  • the guide device enables, so to speak, the "blind" connection of the Bowden cable to the auxiliary closing drive without the user having to steer the end piece of the soul in any way.
  • the auxiliary closing drive has a guide device for the Bowden cable core, which guides the core end piece in the course of the threading movement into positive, drive-related engagement with the core receptacle of the adjusting element located in the housing interior.
  • connection of the Bowden cable to the auxiliary closing drive is possible at every stage of production.
  • the auxiliary closing drive can be transported to its installation position on the motor vehicle without a connected Bowden cable.
  • the connection of the Bowden cable can accordingly be made at any later time.
  • the provision of the Bowden cables in production is also particularly simple, since the Bowden cables can now be transported in the disconnected state. In this way, a plurality of Bowden cables can easily be handled and provided in bundles.
  • the proposed solution allows a simple creation of variants for an auxiliary closing module comprising auxiliary closing drive and Bowden cable connected to it.
  • This creation of variants for the assembly module can in turn take place at any point in time in production.
  • Such a closing aid module should also be claimable as such.
  • the threading-in movement can be a particularly straight-line insertion movement of the Bowden cable core in an insertion direction.
  • the threading movement is the movement that the operator introduces manually and from outside the drive housing into the Bowden cable core and on the basis of which the core end piece is guided by the guide device.
  • the insertion movement can also comprise an at least slight return movement of the Bowden cable core following the insertion movement. It depends on the design of the guide device which threading movement is required for connecting the Bowden cable.
  • the preferred refinements according to claims 3 and 4 relate to the guidance of the core end piece through the guide device.
  • the guide device is provided at least in part by the drive housing, which allows simple production in plastic injection molding processes.
  • the further preferred refinements according to claims 8 to 11 relate to preferred variants for locking the core end piece into the core receptacle.
  • the spring elasticity required for engaging is preferably due to the spring elasticity of the Bowden cable core itself (claim 9). This is a particularly simple design that can be implemented without additional components and thus inexpensively.
  • the further preferred embodiment according to claim 12 relates to the connection of the cover end piece to the edge of the Bowden cable opening of the drive housing.
  • the implementation of a bayonet connection is a mechanically robust and at the same time easy to assemble variant.
  • a particularly reliable variant consists in that the core end piece can only be connected to the adjusting element when the adjusting element is in the assembly position. Because the assembly position is outside the operating adjustment range associated with the auxiliary closing operation, inadvertent loosening of the positive engagement between the core end piece and the core receptacle during the auxiliary closing operation can be prevented in a simple manner.
  • the further preferred embodiment according to claim 14 relates to the operator's release of the positive engagement between the core end piece and the core receptacle. This is necessary, for example, when the auxiliary closing drive is replaced due to wear.
  • the release device provided for release provides an opening in the drive housing through which a tool or the like can be performed. This is a particularly easy-to-implement variant for releasing the form-fitting engagement between the soul end piece and the soul receptacle.
  • a motor vehicle lock arrangement with a motor vehicle lock and a proposed locking auxiliary drive is claimed. It is assumed that the motor vehicle lock has the locking elements lock latch and pawl, the Bowden cable providing a drive connection between the actuating element of the auxiliary locking drive and the lock latch of the motor vehicle lock. Reference may be made to all statements relating to the suggested auxiliary locking drive.
  • a method for assembling a proposed motor vehicle lock arrangement is claimed.
  • the core end piece is brought into positive drive engagement with the core receptacle of the adjusting element in the course of the threading movement.
  • the proposed auxiliary locking drive 1 is used for the motorized adjustment of a lock latch 2, which is usually assigned a pawl 3, of a motor vehicle lock 4 as part of an auxiliary locking process.
  • a lock latch 2 is preferably in a Fig. 2 pre-locking position shown in solid line and in an in Fig. 2 Main closed position shown in dashed line can be brought.
  • the latch 2 cooperates with a locking part 5, which can be a locking bolt, a striker or the like.
  • the motor vehicle lock 4 can be assigned to any locking element of a motor vehicle.
  • the motor vehicle lock 4 is assigned to a motor vehicle door.
  • the motor vehicle lock 4 can, however, also be assigned to a trunk lid, a trunk lid, a front hood or the like. This applies not only to pivotable locking elements, but also to locking elements that are designed in the manner of a sliding door. All the statements relating to a motor vehicle door 6 apply accordingly to all other types of closure elements.
  • the motor vehicle lock 4 is arranged on the motor vehicle door 6, while the locking part 5 is arranged on the motor vehicle body. This can also be provided the other way around.
  • the auxiliary closing process relates to the adjustment of the lock latch 2 from the pre-closed position to the main closed position, which is accompanied by a corresponding closing of the motor vehicle door 6 against the high door seal counterpressures.
  • the auxiliary closing drive 1 has a drive housing 7 with a housing interior 8 and, in the housing interior 8, a drive motor 9 and a drive motor 9 connected downstream about an actuating element axis 10a pivotable adjusting element 10.
  • This basic structure is an overview of the Fig. 1 and 2 refer to.
  • the proposed auxiliary closing drive 1 is a so-called external auxiliary closing drive
  • a Bowden cable 11 provided to divert drive movements can be connected to the auxiliary closing drive 1.
  • the actuating element 10 can be coupled in terms of drive technology to the Bowden cable 11 in order to divert the drive movements.
  • the Bowden cable 11 has in the usual way a Bowden cable sleeve 12 and a Bowden cable core 13, the actuating element 10 having a core receptacle 14 for drive engagement with a core end piece 15 of the Bowden cable core 13, here and preferably spherical.
  • the core end piece 15 is quite generally a body which is attached to the wire-shaped section 16 of the Bowden cable core 13.
  • the core end piece 15 is used to produce the positive engagement with the core receptacle 14 of the adjusting element 10.
  • any other configurations can be used which enable the positive engagement.
  • the drive housing 7 has a Bowden cable opening 17 for threading the Bowden cable core 13 in a threading movement 18, 19.
  • the threading movement 18, 19 is impressed into the Bowden cable core 13 from outside the drive housing 7.
  • the impression of the threading movement 18 19 into the Bowden cable core 13 is provided here and preferably manually, that is, based on a user movement. In the simplest case, when the motor vehicle lock 4 is not yet connected to the Bowden cable 11, this takes place from the core end piece 21 assigned to the motor vehicle lock 4.
  • the threading is carried out in an automated manner, for example by a motorized assembly device.
  • FIG. 3a-d A preferred threading movement results from the sequence of Figures 3a-d .
  • This illustration shows that the auxiliary closing drive 1 has a guide device 20 for the Bowden cable core 13.
  • the guide device 20 guides the core end piece 15 in the course of the threading movement 18, 19 in a form-fitting drive-related engagement with the core receptacle 14 of the actuating element 10 located in the housing interior 8.
  • a look at the representation according to Fig. 3 reveals that the threading movement 18, 19 is an insertion movement of the Bowden cable core 13 for inserting the inner end piece 15 into the Bowden cable opening 17 in an insertion direction 22, which is followed by an at least slight return movement of the Bowden cable core 13 against the insertion direction 22. It is noticeable here that the deflection of the core end piece 15 for threading into the core receptacle 14 is taken over exclusively by the guide device 20, which is yet to be explained. This makes threading particularly easy for the user or the motorized handling device that may be provided.
  • the drive housing 7 is a two-part drive housing with a first housing half 7a and a second housing half 7b, which are connected to one another while the core end piece 15 is being threaded in. Disassembling one of the housing halves 7a, 7b is advantageously not necessary for the proposed threading in of the core end piece 15.
  • the guide device 20 has at least one guide surface 20a, which is provided by the drive housing 7.
  • the guide device 20 has several, in particular web-like guide surfaces 20a, 20b, which are provided partly by the drive housing 7 and partly by the actuating element 10.
  • the guide surfaces 20a are provided by the drive housing 7 and the guide surfaces 20b are provided by the actuating element 10.
  • the movement-guiding function of the guide device 22 is based on the threading-in movement 18, 19 of the Bowden cable core 13. Accordingly, it is provided that the guide device 20 deflects the Bowden cable core 13, here and preferably the core end piece 15, to guide it into positive engagement with the core receptacle 14 of the actuating element 10 laterally, i.e. transversely to the Bowden cable extension 23.
  • the Bowden cable extension 23 is defined here and preferably by the center line of the Bowden cable core 13.
  • a particularly simple structural design results from the fact that the core receptacle 14 has an undercut surface 24 which is designed in such a way that with an existing form fit between the core end piece 15 and the core receptacle 14 ( Fig. 3d )) a return movement of the Bowden cable core 13 pushes the core end piece 15, here and preferably with the actuating element 10 in an assembly position to be explained, further into the form fit with the core receptacle 14. This results in a self-holding effect which leads to a particularly reliable connection of the Bowden cable 11 to the adjusting element 10.
  • the drive housing 7 is designed to be liquid-tight. It is like in Fig. 1 shown, preferably provided that the auxiliary closing drive 1 is arranged in the wet area of the motor vehicle door 6.
  • the drive housing 7 has two housing halves 7a, 7b, which are connected to one another during the threading of the core end piece 15 as proposed.
  • the two housing halves 7a, 7b are sealingly connected to one another.
  • a variant which is particularly advantageous in terms of sealing technology results from the fact that one of the two housing halves 7a, 7b provides the complete Bowden cable opening 17. This is because it ensures that the Bowden cable opening 17 is made of the same material over its entire circumference.
  • the guide device 20 preferably has an insertion channel 25 for the core end piece 15.
  • the insertion channel 25 extends between the Bowden cable opening 17 and the adjusting element 10.
  • the insertion channel 25 can be more or less spaced from the Bowden cable opening 17 and / or the adjusting element 10.
  • the insertion channel 25 extends from the Bowden cable opening 17 to the core receptacle 14 of the actuating element 10, which is here and preferably in an assembly position to be explained. This means that the insertion channel 25 from the Bowden cable opening 17, starting in the direction of the core receptacle 14 of the adjusting element 10, here and preferably in the assembly position.
  • the insertion channel 25 receives the Bowden cable core 13 with the core end piece 15 both transversely to the adjusting element axis 10a and longitudinally to the adjusting element axis 10a in a form-fitting manner.
  • the insertion channel 25 initially has two side walls 25a, 25b, which are formed here and preferably by the housing half 7a.
  • the bottom wall 25c of the insertion channel 25, which extends essentially perpendicular to the side walls 25a, 25b, is also formed by the housing half 7a.
  • the top wall 25d of the insertion channel 25, on the other hand, is formed by the other housing half 7b, as shown in FIG Fig. 2 is only indicated.
  • the guide device 20 together with the core receptacle 14 and the Bowden cable core 13 forms a latching device such that the core end piece 15 engages in positive engagement with the core receptacle 14 in the course of the threading movement 18, 19.

  • Various advantageous implementation variants are conceivable for realizing such a locking device.
  • the representation according to Fig. 3 shows a structurally particularly simple and at the same time particularly operationally reliable embodiment.
  • Fig. 3 shows that the guide device 20 in the course of the insertion movement ( Fig. 3a ), b)) deflects the inner end piece 15 laterally against the resilient restoring force of the Bowden cable core 13 and thereby laterally biases it.
  • the term “laterally” always means, as indicated above, a direction transverse to the Bowden cable extension 23.
  • the guide device 20 releases the core end piece 15 into the core receptacle 14 of the adjusting element 10, which is here and preferably in the assembly position. This means that based on the in Figure 3b ) situation shown, a slight, further insertion movement would result in the soul end piece 15 engaging in the soul receptacle 14.
  • the lateral pre-tensioning of the Bowden cable core 13 is achieved here and preferably in a particularly simple manner in that the guide arrangement 20 has a contact surface 26 which is arranged on the actuating element 10 and which in the course of the insertion movement of the core end piece 15 leads to the lateral deflection and thus the pre-tensioning of the Bowden cable core 13 leads.

  • the guide device 20 has a catching device 27 which is arranged on the adjusting element 10 and has a catching channel 28 which connects to the core receptacle 14. What is achieved thereby is that the guide device 20 guides the core end piece 15, passing over the core receptacle 14, into the catching channel 28 in the course of the insertion movement.
  • the catching channel 28 is here and preferably bent in the shape of a circular arc around the adjusting element axis 10a.
  • the catching channel 28 receives the core end piece 15 in a form-fitting manner both transversely to the adjusting element axis 10a and longitudinally to the adjusting element axis 10a.
  • Driving over the core receptacle 14 is realized here and preferably in that an overrun contour 29 adjoins the core receptacle 14, which causes the core end piece 15 to be ejected from the core receptacle 14 when the core end piece 15 is locked and the insertion movement continues.
  • the result of the catch channel 28 is that a certain outlet is available for the soul end piece 15, which ensures that insertion movements of different dimensions are possible without the soul end piece 15 becoming blocked.
