[0001] Description

[0002] Motor vehicle lock

[0003] The invention relates to a motor vehicle lock, in particular a motor vehicle door lock, with a locking mechanism consisting essentially of a rotary latch and a locking pawl, further with a closing device for the locking mechanism, further with an opening device for a door leaf, and with at least one electromechanical drive which has two directions of rotation, wherein the drive, via an intermediate gearbox, selectively a) acts on a flexible connecting element for the closing action of a locking mechanism part or b) on an opening lever which pushes the door leaf from a closed position into a gap position relative to a motor vehicle body.

[0004] Due to increasing demands for comfort and aerodynamics, motor vehicles are increasingly being equipped with a soft-close mechanism and a door stay. The soft-close mechanism allows a vehicle door lock to be moved from a partially closed position (e.g., manually closed) to a fully closed position. The partially closed position is detected by a sensor. A control unit then receives a signal and sends a command to the electric motor, which then pulls the lock into the fully closed position.

[0005] This can happen in a variety of ways, for example, by applying thrust to a latch that engages a rotary bolt of the locking mechanism, thereby pivoting the latch from its pre-locked position to the main locking position, and possibly into an overtravel position beforehand. This results in improved comfort because the closing action may have to overcome high counterforces from a surrounding seal attached to the door leaf.

[0006] In addition to comfort improvements such as a soft-close mechanism for the lock, aerodynamic optimizations are playing an increasingly important role. These include, for example, eliminating the need for an exterior door handle. To still allow the door to be opened, a door-opening mechanism ensures that the door leaf is pushed from its closed position into a gap relative to the vehicle body. This gap allows the door leaf to occupy a space between the vehicle body and the vehicle body, through which an operator can, for example, reach in and manually swing the door open. Of course, it is also conceivable that, starting from the gap position, the door leaf could be opened electrically by an additional opening mechanism.

[0007] Since, for the reasons described, the opening device essentially replaces an external door handle and therefore interacts with, or must interact with, the vehicle lock because opening the door leaf requires a previously opened lock, the opening device can conceptually be considered part of the vehicle lock. The term "vehicle lock" is therefore to be interpreted broadly within the scope of this application and covers not only the lock and thus directly interacting levers, but also all indirectly interacting auxiliary components such as the closing mechanism and the opening device in or on the door leaf that houses the vehicle lock.

[0008] According to the applicant's state of the art in WO 2022 / 127985 A1, a

[0009] A method for closing and opening a motor vehicle door and a motor vehicle lock are described. This includes a drive unit with which the locking pawl can be disengaged. A closing mechanism is also provided, which moves the locking mechanism from the pre-latch position to the main latch position. Furthermore, a clutch element can be controlled by the drive unit associated with the locking pawl in such a way that, by engaging the closing mechanism, the motor vehicle door can be opened.

[0010] WO 2023 / 104236 A1, also originating from the applicant, concerns a motor vehicle lock that has a closing mechanism and a lifting mechanism. With the aid of an associated drive unit, a coupling element can again be controlled in such a way that the closing mechanism enables the lifting and closing of the associated door element or door leaf.

[0011] The closest prior art, which defines the category of the technology, according to EP 3 640 419 B1, relates to a motor vehicle lock with a push-to-open mechanism and a closing aid. The push-to-open mechanism is equipped with a push-to-open lever by which a corresponding motor vehicle door can be pushed open from a closed position to a push-to-open position in a single action. This creates an engagement gap between the motor vehicle door and the vehicle body.

[0012] The locking aid is equipped with a locking aid lever, which, in the installed state, moves the lock latch or rotary latch from a pre-locked position to a fully locked position in a single locking aid operation. In addition, a separate drive mechanism is provided, with the vehicle lock being coupled to the drive mechanism via a Bowden cable.

[0013] The vehicle lock features a switchable clutch assembly which, when installed, transmits an actuation stroke transmitted via the Bowden cable, depending on the clutch's state, either to the pushing mechanism or the pushing lever, or to the closing mechanism or the closing lever leading to the lock latch. In other words, the additional switchable clutch assembly ultimately distinguishes between a pulling and a pushing action.

[0014] The prior art, as defined in EP 3 640 419 B1, has proven fundamentally sound, but still offers room for improvement. In fact, the switchable clutch arrangement implemented in detail is mechanically quite complex and therefore prone to malfunctions. For example, it incorporates a transmission lever which, when actuated, engages the push-up lever or the closing lever. The closing lever is pivotally mounted on the transmission lever. Furthermore, the push-up mechanism is equipped with an intermediate lever, which is also pivotable about the axis of rotation of the transmission lever. The intermediate lever is coupled to the push-up lever via an additional toothed connection to transmit torque.

[0015] In any case, due to the mechanically complex design of the switchable clutch assembly, reliable long-term functionality cannot be guaranteed, and this design also involves increased manufacturing and assembly costs. The invention aims to remedy this situation.

[0016] The invention is based on the technical problem of further developing such a motor vehicle lock, and in particular a motor vehicle door lock, in such a way that, taking into account a compact and inexpensive design, functional reliability is also guaranteed over long time scales.

[0017] To solve this technical problem, a generic motor vehicle lock within the scope of the invention is characterized in that different gear elements are actuated depending on the direction of rotation of the drive, wherein in one direction of rotation of the drive, closing gear elements actuate the flexible connecting element and in another direction of rotation of the drive, opening gear elements actuate the opening lever.

[0018] The invention is distinguished, firstly, by the fact that it deliberately and expressly dispenses with the switchable clutch arrangement, which is particularly emphasized and highlighted in the closest prior art according to EP 3 640 419 B1. Instead, the switching between a closing and a closing operation is achieved by different gear elements ensuring the power flow of an electric motor, as part of the electric motor drive, via the downstream gearbox. For this reason, a distinction is made between closing gear elements and opening gear elements. While the closing gear elements actuate the flexible connecting element in one direction or direction of rotation of the drive, the other, differing direction of rotation of the drive results in the opening gear elements acting upon the opening lever.

[0019] The closing gear links and the opening gear links each represent components or gear links of the gearbox that follows or is interposed between the electric motor drive and, on the one hand, the flexible connecting element for applying the closing action to the locking mechanism, or on the other hand, the opening lever that pushes the door leaf open. The closing gear links and the opening gear links of the gearbox can at least partially coincide, as long as the power flow is directed to the flexible connecting element on the one hand and to the opening lever on the other, due to the different directions of rotation of the drive. That is, while the closing gear links and the opening gear links can partially coincide, they must differ in at least one gear link to define the differing power flow depending on the direction of rotation.This occurs selectively, following a logical "either-or" relationship. That is, the electric drive, and typically the electric motor, either operates in one direction of rotation on the flexible connecting element via the closing gear links. Or, in the other direction of rotation, the drive or electric motor ensures that the opening lever is actuated via the opening gear links.

[0020] For the electric motor drive itself, and potentially also the transmission, there are various possibilities for implementation and arrangement. For example, the electric motor drive can be housed in its own separate housing, independent of the vehicle lock. The same applies to the transmission. Furthermore, the electric motor drive, and in particular the electric motor implemented here, on the one hand, and the transmission on the other, can be housed and positioned in a common housing, separate from the vehicle lock housing. Finally, it is also possible to implement hybrid designs, such that, for example, the transmission is located within the vehicle lock housing, while the electric motor drive is housed outside the vehicle lock housing in its own separate housing.Finally, it is also within the scope of the invention to house the electric motor drive, including the gearbox and lifting lever, in a separate housing, which is designed and positioned separately from the lock housing or the housing for the vehicle lock. The necessary connection to the vehicle lock can be achieved via the flexible connecting element. This is the most common approach. Of course, a housing that accommodates all the aforementioned components is also conceivable.

[0021] Furthermore, the design is such that the transmission is configured as an epicyclic gear unit, and in particular a planetary gear unit. For this purpose, the planetary gear unit in question is equipped with a sun gear, planet gears, a planet carrier, and a ring gear. In this context, the design is advantageously further modified such that the sun gear, the planet gears, and the planet carrier are configured as the aligning gear elements. In contrast, the sun gear, the planet gears, and the ring gear are the engaging gear elements.

[0022] That is, the opening and closing gear components are at least partially identical, according to the exemplary embodiment in that in both cases the sun gear and the planet gears are included in the power flow, on the one hand to actuate the flexible connecting element for the closing movement and on the other hand to actuate the opening lever for pushing open the door leaf. A deviation exists only with regard to the planet gear carrier as the opening gear component and the ring gear as the closing gear component.

[0023] The invention takes advantage of the fact that in such epicyclic gear drives, and especially planetary gear drives, the power flow can be easily varied by subjecting the gear drive, and in particular the input sun gear, to a different direction of rotation from the electric motor drive. This will be explained in more detail with reference to the exemplary embodiment. Furthermore, in this context, the ring gear and the planet carrier are advantageously each equipped with a stop.

[0024] To actuate the flexible connecting element and thus achieve a tightening movement, the planetary gear carrier moves against its stop. Conversely, the lifting movement II corresponds to the ring gear moving against its stop to actuate the lifting lever.

[0025] The flexible connecting element for applying the actuating force to the locking mechanism is typically attached to the ring gear. The actuating lever is usually a rack and pinion lever. A gear connected to the planet carrier generally engages with the rack and pinion lever to adjust its position. Of course, other methods of actuating the actuating lever via the planet carrier are also conceivable, for example, if the rotational movement of the planet carrier is transmitted to the actuating lever via a cable.

[0026] In this context, it is also conceivable that a spring is associated with the planetary gear carrier. This spring allows the lifting lever to be reset after a lifting operation has been completed. For this purpose, the spring in question is tensioned during a lifting operation and when the lifting lever is extended. The invention also relates to a method for closing and lifting a door leaf equipped with a motor vehicle lock, as explained in more detail in claim 10.

[0027] The result is a description of a motor vehicle lock and an associated method, characterized by a compact and cost-effective design, simple assembly, and particularly reliable operation. This can be attributed to the fact that it operates solely with an electric motor drive and an intermediate gearbox, enabling the various functions of closing, pushing, and opening.

[0028] The key element of these different functions is the gearbox, which, depending on its direction of rotation, provides and implements a different power flow for the closing movement on the one hand and for the opening movement on the other. This is where the main advantages lie.

[0029] The invention will now be explained in more detail with reference to a drawing that illustrates only one embodiment; the drawing shows:

[0030] Fig. 1 shows the vehicle lock according to the invention and the associated vehicle door during an installation process and

[0031] Fig. 2 shows the object according to Fig. 1 in connection with a

[0032] Closing process. The figures initially depict a motor vehicle lock, designed as a motor vehicle door lock 1, which is arranged in or on an indicated door leaf 2. For this purpose, the motor vehicle door lock 1 has a locking mechanism 3, 4 consisting of the two locking parts rotary latch 3 and locking pawl 4. Additionally, inside a housing 5 that accommodates the locking mechanism 3, 4, a transmission lever 6 and an actuating pawl 7 can be seen. With the aid of the actuating pawl 7, the rotary latch 3 can be actuated from a pre-latch position to a main latch position in the closing direction.

[0033] For this purpose, the drive pawl 7 is pivotally connected to the transmission lever 6, which itself is a two-armed lever, pivotally connected to the drive pawl 7 on one side and actuated via a flexible connecting element 8 on the other. The flexible connecting element 8 exerts tension on the transmission lever 6, causing it to pivot counterclockwise about its indicated axis to close the locking mechanism 3, 4. The counterclockwise movement of the transmission lever 6 results in the drive pawl 7, which is pivotally connected to it, being subjected to thrust and thus moving against an indicated lug of the rotary latch 3. As a consequence, the rotary latch 3 pivots clockwise about its axis. This can be seen during the closing process as shown in Fig. 2.

[0034] The clockwise rotation of the rotary latch 3 results in a locking bolt 9, which is caught by the rotary latch 3, being moved "to the left" during the closing movement, as shown in Fig. 2. Since the locking bolt 9 is connected to a vehicle body 10, this closing process causes the door leaf 2, which houses the vehicle door lock 1, to move in the closing direction towards its closed position relative to the vehicle body 10.

[0035] In this way, a closing device 6, 7, 8 is provided for the locking mechanism 3, 4, which essentially consists of the transmission lever 6 and the drive pawl 7 as well as the flexible connecting element 8, which acts on the transmission lever 6 to apply a closing action to a locking mechanism part 3, 4, in the exemplary embodiment the rotary latch 3. For this purpose, and without limitation, the flexible connecting element 8 is a Bowden cable.

[0036] Independently and separately from the vehicle door lock 1 and its associated housing 5, an electric motor drive 11, 12 is also implemented. Furthermore, a lifting device 13, 14, 15 for the door leaf 2 is provided. The electric motor drive 11, 12 and the lifting device 13, 14, 15 can also be placed within the housing 5, but according to the example shown, they may be accommodated in a common housing 22, which will be described in more detail below. The lifting device 13, 14, 15 essentially consists of a lifting lever 13 designed as a rack and pinion lever and a gear 14, 15 engaging with the rack and pinion lever or lifting lever 13. In this embodiment, the gear 14 interacts with another gear 15, which will be described in more detail below. It can be seen that both gears 14, 15 are connected to each other in a rotationally fixed manner about a common axis.Furthermore, each gear 14,15 engages with a corresponding toothing on the setting lever 13.

[0037] The basic assembly also includes a gearbox 16, 17, 18, 19 following the electric motor drive 11, 12. The gearbox 16, 17, 18, 19 is interposed between the electric motor drive 11, 12 and the flexible connecting element 8 or the setting lever 13. The electric motor drive 11, 12 has two directions of rotation. It consists of an electric motor 11 and an output gear 12, which the electric motor 11 rotates via an output worm located on its output shaft. The output gear 12, and thus the electromechanical drive 11, 12, can describe or have two directions of rotation: a clockwise rotation used in Fig. 1 for an erection process and a counterclockwise rotation required for a tightening process in the illustration according to Fig. 2.

[0038] In this way, the electric motor drive 11, 12 can selectively act on the opening lever 13 via the intermediate gearbox 16, 17, 18, 19. This lever pushes the door leaf 2 from a closed position to a slightly ajar position relative to the vehicle body 10. This process is illustrated in Fig. 1 and corresponds to the clockwise rotation of the output gear 12 of the electric motor drive 11, 12 indicated therein. As a result, the opening lever 13 is extended relative to the door leaf 2 in the direction of the arrow shown in Fig. 1, thereby pushing the door leaf 2 open relative to the vehicle body 10. To achieve this, the opening lever 13 moves against the vehicle body 10 or a fixed stop within the body.

[0039] This differs from the closing process shown in Fig. 2. In this case, the electric motor drive 11, 12 acts via the intermediate gearbox 16, 17, 18, 19 on the flexible connecting element 8, specifically to apply a closing force to a locking component 3, 4. In fact, the closing force on the flexible connecting element 8 corresponds to the transmission lever 6 being pulled in the direction of the arrow and thereby pivoting counterclockwise, so that the drive pawl 7 is subjected to a pushing force. As a result, the rotary latch 3 is pivoted clockwise and the door leaf 2 is pulled towards the vehicle body 10, as already described in the introduction.

[0040] Of particular importance for the invention is the fact that different gear elements 16, 17, 18, 19 are actuated depending on the direction of rotation of the electric motor drive 11, 12. In fact, in one direction of rotation of the electric motor drive 11, 12, according to the exemplary embodiment, during a counterclockwise movement of the output gear 12, the tightening gear elements 16, 17, 19 actuate the flexible connecting element 8 (see Fig. 2). In the other direction of rotation of the electric motor drive 11, 12, consequently in a clockwise rotation of the output gear 12, the actuating gear elements 16, 17, 18 of the gearbox 16, 17, 18, 19 are actuated in order to be able to act on the actuating lever 13 to raise the door leaf 2 relative to the motor vehicle body 10 (see Fig. 1).

[0041] This is implemented and realized in detail as follows. In fact, the transmission 16, 17, 18, 19 in the exemplary embodiment, and without limitation, is a planetary gear transmission. This is equipped with a sun gear 16, planet gears 17, a planet carrier 18, and finally a ring gear 19. The sun gear 16, the planet gears 17, and the planet carrier 18 define the aligning gear elements 16, 17, 18. In contrast, the

[0042] The draw-gear links 16, 17, 19 are defined by the sun gear 16, the planet gears 17, and finally the ring gear 19. It can also be seen that the ring gear 19 is equipped with an associated stationary stop 20.

[0043] The same applies to the planetary gear carrier 18, which is also equipped with a stationary stop 21. Both stops 20, 21 can be defined in a housing 22, which is only indicated and accommodates the mounting device 13, 14, 15 together with the electric motor drive 11, 12 and the intermediate gearbox 16, 17, 18, 19. The housing 22 in question may be designed independently and spatially separate from the housing 5 for the vehicle door lock 1. Of course, both housings 5, 22 can also be combined to form a single housing, which is not shown. The operating principle is as follows.

[0044] Figure 1 illustrates an installation process. For this purpose, the electric motor drive 11, 12 is subjected to a first direction of rotation, which, according to the exemplary embodiment, corresponds to the clockwise rotation of the output gear 12 indicated therein. Since the sun gear 16 is integrally formed with the respective output gear 12, the sun gear 16 of the planetary gear also rotates clockwise. The clockwise rotation of the sun gear 16 causes the planet gears 17 to roll counterclockwise within the ring gear 19, and the ring gear 19 moves against its stop 20 and is thus locked. Since the ring gear 19 is consequently stationary, the flexible connecting element 8 is not subjected to any force during the installation process shown in Figure 1.

[0045] The planet gears 17 perform a counterclockwise rotation within the ring gear 19, as indicated in Fig. 1. The planet carrier 18, which carries the planet gears 17, follows this counterclockwise rotation. Consequently, it moves away from its associated stop 21. A spiral spring 23 is associated with the planet carrier 18. One end of the spiral spring 23 is connected to the planet carrier 18, and the other end acts on the gear 15. This gear 15 therefore also performs a counterclockwise rotation, as indicated in Fig. 1, following the planet carrier 18.

[0046] The counterclockwise rotation of gear 15 is transmitted to gear 14, which is non-rotatably connected to it and consequently also rotates counterclockwise. The counterclockwise rotation of gear 14 (and also of gear 15) is then transmitted to the actuating lever 13, which is designed as a rack and pinion lever. As a result, the actuating lever 13 is moved and raised in the direction of the arrow as shown in Fig. 1. Consequently, the actuating lever 13 causes the door leaf 2 to be pressed open against the vehicle body 10.

[0047] During or towards the end of the opening process, the spring 23 becomes increasingly tensioned. As a result, after the opening process is complete, the spring 23 can return the opening lever 13 to its retracted home position. This is, of course, only an example and is not mandatory. Figure 2 does not depict the opening or opening process described above, but rather a closing process. This corresponds to an application of force to the electric motor drive 11, 12 in the opposite direction, i.e., the other direction of rotation, which, according to the exemplary embodiment, is accompanied by a counterclockwise rotation of the output gear 12, as indicated in the relevant Figure 2. The counterclockwise rotation of the drive gear 12 is transmitted to the sun gear 16 in the same way. As a result, the planet gears 17 no longer roll counterclockwise inside the ring gear 19, but rather clockwise.This means that the planetary gear carrier 18 also completes a clockwise rotation and thus moves against its stop 21 and is consequently held in place. Accordingly, during a tightening process as shown in Fig. 2, the setting lever 13 is not actuated.

[0048] Rather, the clockwise rolling motion of the planet gears 17 within the ring gear 19 causes the ring gear 19 to rotate in the opposite direction, namely counterclockwise, and consequently away from its stop 20. The counterclockwise rotation of the ring gear 19 with the planet carrier 18 stationary results in tension being applied to the flexible connecting element 8 attached to the ring gear 19. This tension on the connecting element 18 causes the transmission lever 6 to pivot counterclockwise, resulting in the closing movement of the locking mechanism 3, 4. The door leaf 2 is thus moved into its closed position relative to the vehicle body 10 in a closing direction.

[0049] Additionally, the figures show an optional coupling 24. Also shown is a spring-assisted friction- or positive-locking detent 25, which is associated with the ring gear 19. This also applies to another spring-assisted friction- or positive-locking detent 26, which may be associated with the planet carrier 18. In this way, the two detent mechanisms 25 and 26 can each be used as return aids to return the ring gear 19 and the planet carrier 18, respectively, to their initial positions at the corresponding stops 20 and 21.

[0050] Alternatively, with the optional clutch 24, it is possible to reset the ring gear 19 or the planet carrier 18, respectively, as needed, using an additional motor (not shown). For this purpose, the clutch 24 is disengaged during the previously described tightening or pushing operation and is only engaged to reset the ring gear 19 or the planet carrier 18, in order to execute the reset movement with the small motor (not shown). The clutch 24 is naturally not required for the basic operation.
