Definitions
- the invention relates to the combination of a motor vehicle lock and a motor vehicle lock functional unit, wherein the motor vehicle lock and the motor vehicle lock functional unit are each designed to be modular, preferably with their own housing, and largely spatially and functionally separated from one another, furthermore the motor vehicle -Lock and the motor vehicle lock functional unit are mechanically coupled to one another by a connecting means, and wherein the motor vehicle lock functional unit has an electric motor drive and interacts with a locally remote actuator.
- the motor vehicle lock functional unit is, within the scope of the generic and starting point prior art according to DE 10 2019 110480 A1, a so-called double locking arrangement.
- a blocking state can be implemented as a functional state of the associated motor vehicle lock.
- an anti-theft device is implemented and provided in such a way that an interior door handle experiences a mechanical blockage. This is due to special anti-theft regulations in certain markets.
- the modular and typically spatially and functionally separate design of the motor vehicle lock and the motor vehicle lock functional unit offers in this context the possibility of implementing the motor vehicle lock functional unit in question or not if necessary. This allows specific functions to be implemented optionally. Retrofitting such a lock function is also possible, so that a motor vehicle lock serves as a basis and the corresponding removal or Upgrade variants can be used with which the motor vehicle lock in question is equipped.
- the double locking arrangement ensures a mechanical blockage of the inside door handle, which may lead to damage to the inside door handle and/or the connecting means for the mechanical coupling.
- the functionality is limited.
- the invention as a whole aims to provide a remedy here.
- the invention is based on the technical problem of further developing such a combination of a motor vehicle lock and a motor vehicle lock functional unit in such a way that damage can be reliably avoided and an expanded range of applications can be realized.
- a generic combination of a motor vehicle lock and a motor vehicle lock functional unit is characterized in the context of the invention in that the motor vehicle lock functional unit has a coupling element that can be controlled using the electric motor drive to implement security functions, which in When engaged, a continuous mechanical connection is defined from the actuator to the motor vehicle lock and when disengaged, an interrupted mechanical connection from the actuator to the motor vehicle lock is defined.
- the invention works with a coupling element and not with a blocking element. In this way, a continuous mechanical connection can be made when the coupling element is engaged Will be provided.
- loading of the actuating member means that the motor vehicle lock is also acted upon accordingly, and as a rule a locking mechanism as part of the motor vehicle lock is opened.
- a pawl as part of the locking mechanism is usually lifted from its latching engagement with a rotary latch using the actuating member.
- the clutch is disengaged, such a locking mechanism opening is not possible because the mechanical connection is then interrupted.
- the actuator is usually designed locally and functionally by the motor vehicle lock functional unit and accordingly also the motor vehicle lock.
- the actuator can be an outside door handle, an inside door handle or a lock cylinder individually or in combination.
- the invention of course also includes variants such that both an outside door handle and an inside door handle and, if necessary, additionally a locking cylinder are implemented, which work on the motor vehicle lock via the motor vehicle lock functional unit if there is a continuous mechanical connection. If, on the other hand, the mechanical connection is interrupted, it is not possible to act on the motor vehicle lock and in particular to open the lock using the actuator.
- the actuating member is typically an outside door handle, which is mechanically connected to the locking mechanism of the motor vehicle lock when the coupling element is engaged.
- the “unlocked” state corresponds to this. If, on the other hand, the safety function is to be displayed “locked”, the coupling element is in its disengaged state transferred so that the mechanical connection is interrupted.
- an additionally provided inside door handle may be continuously connected to the motor vehicle lock.
- a “child-proof/child-unlocked” security function can also be implemented.
- the actuator is an inside door handle in the shelf on a rear motor vehicle side door.
- the functional position “child-proof” corresponds to the fact that in this case the coupling element is disengaged as part of the intermediate motor vehicle lock functional unit, so that pressure on the inside door handle is empty. If, on the other hand, the coupling element is engaged, this leads to the functional position “child unlocked”.
- an associated outside door handle may be mechanically connected throughout to the motor vehicle lock.
- both an outside door handle and an inside door handle are implemented as an actuating element.
- the coupling element In the “theft-proof” functional state, the coupling element is disengaged, so that both the external door handle and the internal door handle are deactivated. If, on the other hand, the motor vehicle lock functional unit is in the functional position "unlocked against theft", the coupling element is engaged and both the outside door handle and the inside door handle are able to work mechanically on the locking mechanism of the motor vehicle lock and to act on it in an opening manner .
- the actuator can also be a locking cylinder.
- the coupling element is, as it were, bypassed and an action on the locking cylinder in the sense of “opening” or “unlocking” ensures that the continuous mechanical connection to the motor vehicle lock is used in such a way that the locking mechanism experiences opening.
- a “closing” or “locking” process on the locking cylinder ensures that, for example, a previously designed anti-theft device or the “theft-unlocked” functional position is canceled again and the coupling element is disengaged accordingly.
- the coupling element is acted upon by means of a contour or coupling contour on an output pulley as part of the electric motor drive.
- the electric motor drive assigned to the motor vehicle lock functional unit is typically composed of at least one electric motor and the relevant driven pulley.
- the output pulley is now equipped with a contour or coupling contour, with the help of which the coupling element is acted upon, namely its described functional positions “engaged” or “disengaged” either and depending on the control of the electric motor drive.
- the coupling element is usually and advantageously rotatably connected to an actuating lever.
- the actuating lever can in turn be set up to interact with the driven pulley.
- the contour or clutch contour on the output pulley ensures that the clutch element is not acted upon directly with its help, but rather the actuating lever, which in turn adjusts the clutch element.
- the design is such that the coupling element mechanically couples a release lever and the actuation lever to one another when the clutch is engaged.
- the disengaged state of the clutch element therefore corresponds to the release lever and the actuating lever being mechanically separated from one another. This provides the desired mechanical interruption.
- the procedure can be further and advantageously carried out in such a way that the release lever and the actuating lever are mounted on the same axis as one another.
- the electric motor drive is set up not only to implement security functions, but also to open the motor vehicle lock by electric motor.
- the one (single) electric motor drive takes over the implementation of the different safety functions, as already described in the introduction.
- the electric motor drive is also capable of electric motor opening of the motor vehicle lock. This provides a particularly cost-effective and compact structure because a single electric motor drive is used. In principle, two separately designed electric motor drives can also be implemented and implemented at this point, although this is not preferred.
- the output pulley is advantageously equipped with, on the one hand, the coupling contour for acting on the coupling element and, on the other hand, an additional release contour for acting on the release lever.
- the design is advantageously such that the clutch contour and the release contour are shaped on opposite surfaces of the driven pulley.
- the previously mentioned release lever as part of the motor vehicle lock functional unit is in turn coupled via the connecting means to the already mentioned locking mechanism as part of the motor vehicle lock.
- a coupling of the release lever with a pawl of the locking mechanism which essentially consists of a rotary latch and a pawl, is observed.
- This can be the case with this Mechanical connecting means can advantageously be a flexible mechanical connecting means such as a cable or Bowden cable.
- the motor vehicle lock functional unit which is modular and largely designed locally and functionally by the motor vehicle lock, different security functions can now be optionally implemented within the scope of the invention in connection with the motor vehicle lock.
- the motor vehicle lock functional unit usually has its own housing.
- the housing of the motor vehicle lock functional unit it is also possible for the housing of the motor vehicle lock functional unit to be attached or flanged to that of the motor vehicle lock.
- the local and functional separation is also essential in this context in order to realize the modular character and at the same time open up the possibility of combining the motor vehicle lock with a motor vehicle lock functional unit of the desired design. This is where the main advantages can be seen.
- Fig.1 shows a combination of a motor vehicle lock and a motor vehicle lock functional unit according to the invention in a first variant
- the figures show the combination of a motor vehicle lock 1 and a motor vehicle lock functional unit 2.
- the motor vehicle lock 1 and the motor vehicle lock functional unit 2 are mechanically coupled to one another by a connecting means 3.
- the connecting means 3 is a flexible connecting means 3, for example a Bowden cable or a cable pull.
- the motor vehicle lock 1 and the motor vehicle lock functional unit 2 can be selectively and flexibly placed and installed at different locations inside a motor vehicle door, not shown, but this is not shown in detail.
- the basic structure then includes an actuating member 4, 5 that is locally remote from the motor vehicle lock functional unit 2 and which, according to the exemplary embodiment, is an inside door handle 4 on the one hand and a locking cylinder 5 on the other.
- the motor vehicle lock 1 is equipped with its own housing or lock housing 6. Inside the lock housing 6 and essentially a locking mechanism 7, 8 consisting of a rotary latch 7 and a pawl 8 with usual functionality is stored. In addition, further lock components may also be implemented and provided inside the motor vehicle lock 1, but these are not important in the context of the present invention, so that they are not reproduced for reasons of clarity.
- the motor vehicle lock functional unit 2 is also equipped with its own housing 9. As a result, the motor vehicle lock 1 on the one hand and the motor vehicle lock functional unit 2 on the other hand can each be designed modularly with their own housing 6, 9 and spatially and functionally separated from one another. Both housings 6, 9 may be made entirely or partially from plastic.
- the motor vehicle lock functional unit 2 is essentially equipped with an electric motor drive 10, 11 inside.
- the electric motor drive 10, 11 has an electric motor 10 and an output slide 11, which can be driven and rotated about its axis 12 using a worm located on an output shaft of the electric motor 10.
- the motor vehicle lock functional unit 2 now has a controllable device using the electric motor drive 10, 11 to implement security functions of the motor vehicle lock 1
- Coupling element 13 The coupling element 13, in its engaged state shown in FIG Connection from the actuator 4, 5 to the motor vehicle lock 1 interrupted.
- the coupling element 13 can be acted upon using a coupling contour 14 on the driven pulley 11 as part of the electric motor drive 10, 11.
- the coupling contour 14 in question can be seen.
- the clutch contour 14 is provided concealed on the back of the output pulley 11 and works on the clutch element 13 via an actuating lever 17.
- a clockwise movement of the driven pulley 11, not shown here, about its axis 12 ensures that the coupling element 13 is pivoted and disengaged.
- a previously implemented mechanical connection between an actuation lever 15 and a release lever 16 is interrupted.
- the coupling element 13 is rotatably connected to the release lever 16.
- the coupling element 13 In order to be able to open the locking mechanism 7, 8, the coupling element 13 must be engaged again.
- the worm wheel 11 is rotated in the counterclockwise direction indicated in FIG. 1 and can engage the coupling element 13 again.
- the locking mechanism 7, 8 can now be opened using an actuating lever 20 in the clockwise direction indicated in FIG. 1.
- the connecting means 3 is connected to the pawl 8 and a tensile action on the connecting means 3, indicated by an arrow in the figures, causes the pawl 8 to be pivoted about its axis in the clockwise direction. As a result of this, the pawl 8 is lifted from its latching engagement with the rotary latch 7. Then you can Rotary latch 7 opens with spring support and releases a previously caught locking bolt. The associated motor vehicle door can be opened.
- the additional actuating lever 17 is provided, which in this case is set up to interact with the driven pulley 11.
- the output pulley 11 has the clutch contour 14 already mentioned on its back side, which cannot be seen in FIGS. 2 and 3.
- the actuating lever 17 can now be pivoted during the transition from FIG. 2 to FIG In this way, the coupling element 13 connected to the actuating lever 17 is pivoted about its axis in the counterclockwise direction during the transition from FIG. 2 to FIG. 3.
- the coupling element 13 changes from its “engaged” state according to FIG. 2 to its “disengaged” state as shown in FIG. 3.
- the electric motor drive 10, 11 is not only set up and designed to implement security functions.
- the motor vehicle lock 1 can also be opened by electric motor.
- the output pulley 11 in this case has, in addition to the previously mentioned and invisible clutch contour 14 arranged on the rear surface, also a release contour 18.
- This release contour 18 is designed and able to be cam-shaped according to the exemplary embodiment in FIGS. 2 and 3 , to act on the release lever 16 directly so that the release lever 16 performs a pivoting movement in the counterclockwise direction about its axis 19.
- the locking cylinder 5 as a further actuating member 4, 5 in the context of the variant according to FIG. 1 works on a separate actuating lever 20, the design of which is such that an action on the actuating lever 20 corresponds to the actuating lever 20 via an arm 21, the release lever 16 can act directly, bypassing the coupling element 13. This corresponds to a pivoting movement of the release lever 16 around the axis 19 common to the actuating lever 15 and actuating lever 20 in a clockwise direction. As a result of this, the release lever 16 is acted upon again in the clockwise direction indicated in FIG.
