Motor vehicle lock having a drive

Abstract

The aim of the invention is to provide a motor vehicle lock which exhibits a high push-open force and which is at the same time space-saving and cost-effective to produce. This is achieved by a motor vehicle lock (10) for a movable closure component, said motor vehicle lock having a locking mechanism (12), which has a rotary latch (14) and a pawl (16), and having a drive lever (18). The drive lever is held so as to be movable between an initial position and a deployed position. In order to open the movable closure component, the drive lever is designed such that, during the movement in the direction of the deployed position, a first end (22) of said drive lever acts on the closing element in an opening direction of the movable closure component. At a second end (24) opposite the first end, the drive lever is guided along a guide path (26) between a first and a second position and can be subjected to a primary drive force in the direction of the second position. In the region between the first end and the second end, the drive lever has a longitudinal slot (28) in which a stationary bearing bolt (30) engages in order to guidingly hold the drive lever. The bearing bolt and the longitudinal slot form a displaceable pivot bearing for the drive lever. The distance (32) between the guide path and the bearing bolt decreases from the first position to the second position, such that the force transmission ratio changes.

Description

[0001] Motor vehicle lock with drive

[0002] AREA OF INVENTION

[0003] The present invention relates to a motor vehicle lock for a movable closing component, to a motor vehicle lock module, to a motor vehicle door module and to a method for actuating a motor vehicle lock for a movable closing component.

[0004] BACKGROUND OF THE INVENTION

[0005] The operation of movable end components of a vehicle, such as vehicle doors, can be manual. However, more and more drives are being used, for example, to open or close vehicle doors. For instance, door openers, also known as push-out units, are used in vehicle doors or body areas to open the vehicle door far enough for the user to reach behind it. These additional functions can be performed by separately installed components. Another option is to combine them with a vehicle lock. For example, EP 3640419 Al describes a vehicle lock with a rotary latch and locking pawl and a push-open mechanism with a separately designed push-open lever, which can be used to push open the vehicle door, thereby creating a gap between the vehicle door and the vehicle body.However, it has become apparent that there is a need for door openers that are as compact and powerful as possible, capable of pushing open icy doors, for example, while being as economical as possible.

[0006] SUMMARY OF THE INVENTION

[0007] One object of the present invention is therefore to provide a motor vehicle lock that is capable of providing a large pressing force, and which is at the same time space-saving and inexpensive to manufacture.

[0008] This problem is solved by the subject matter of the independent claims. Further examples are given in the dependent claims. The aspects described below also apply to the motor vehicle lock for a movable closing component, the motor vehicle lock module, the motor vehicle door module, and the method for actuating a motor vehicle lock for a movable closing component, and vice versa. Furthermore, features not explicitly mentioned here can also be freely combined.

[0009] According to the invention, a motor vehicle lock is provided for a movable locking component. The motor vehicle lock has a locking mechanism with a pawl and a rotary latch for holding a locking element, and an actuating lever. The actuating lever is movably held between a neutral position and an extended position. To raise the movable locking component, the actuating lever is designed so that, when moved towards the extended position, its first end acts on the locking element in a raising direction of the movable locking component. The actuating lever is guided at a second end opposite the first end along a guide track between a first and a second position and can be subjected to an actuating force in the direction of the second position.The drive lever has a longitudinal slot in the area between its first and second ends, into which a fixed bearing pin engages to guide the drive lever. The bearing pin and the longitudinal slot form a sliding pivot bearing for the drive lever. The guide track has a decreasing distance to the bearing pin from the first position to the second position, thus changing the force transmission ratio.

[0010] The advantage is a compact design while simultaneously allowing high forces to be applied at the beginning of the setup process.

[0011] The opening mechanism can be compactly integrated into a lock. Pushing or opening the door, also known as a push-out mechanism, can be performed from the lock's lead-in opening without requiring any changes to the door's geometry. Initially, a significant amount of force is available, for example, for ice-breaking. Subsequently, due to the changing leverage ratio, a relatively rapid push-out movement can be achieved.

[0012] According to one example, the guide track is designed as an elongated guide slot. The drive lever has a guide pin at its other end that engages in the guide slot.

[0013] This allows for simple yet robust and durable guidance.

[0014] In one example, the guide track has a curvature. As an option, the curvature is designed to align with the bearing pin.

[0015] The curvature allows for the formation of a changing lever ratio, i.e., translation ratio.

[0016] According to one example, the rotary latch is pivotably held on a rotary latch bearing and the bearing bolt is designed concentrically with the rotary latch bearing.

[0017] The advantages include a compact design and more cost-effective manufacturing.

[0018] According to one example, the rotary latch has a drive boss, and the drive lever rests against the drive boss when the drive lever is moved towards the extended position, in order to move the rotary latch towards an open position by means of the drive lever, so that in a first setting phase the rotary latch acts on the locking element in the setting direction. As an option, it is provided that in a second setting phase the projecting stop acts on the locking element.

[0019] Due to the two-phase design, the system areas can be optimized accordingly. For example, the drive lever can be made slightly narrower in the extending section, since the high pressure forces are applied to the closing element by the rotary latch.

[0020] According to one example, a rotatably mounted drive element is provided, upon which a drive force acts. In an opening direction, the rotatably mounted drive element acts on the guide pin to move the drive lever towards the extended position.

[0021] According to one example, the driving force acts in a first direction on the rotatably mounted drive element in order to move the drive element in the opening direction.

[0022] According to one example, the rotatably mounted drive element also acts on the guide pin in a closing direction of the drive element in order to move the drive element in the direction of the starting position.

[0023] According to one example, the driving force acts in a second direction on the rotatably mounted drive element in order to move the drive element in the closing direction.

[0024] According to one example, the rotatably mounted drive element, in the opening direction, acts on a release lever to release the pawl of the locking mechanism before acting on the guide pin.

[0025] According to one example, the rotatably mounted drive element has a drive contour with at least one projection on a side facing the drive lever. In an opening direction of the drive element, the drive contour rests against the guide pin to move the drive lever.

[0026] For example, the drive contour has a first projection that rests against the guide pin in the opening direction of the drive element to move the drive lever towards the extended position. Optionally, the drive contour also has a second projection that rests against the guide pin in the closing direction of the drive element to move the drive lever towards the initial position.

[0027] According to one example, a rotatably mounted rotary lever is provided for the rotatably mounted drive element, upon which a drive force acts. The rotary lever has a first lever segment which rests against the guide pin to move the drive lever in one direction of the extension position, i.e., the opening direction of the rotary lever.

[0028] According to one example, the driving force acts on a rotatably mounted drive element, which transmits the driving force to the rotary lever. Optionally, the drive element is rotatably mounted concentrically with the rotary lever and has a drive projection that engages axially in a receptacle of the rotary lever.

[0029] According to one example, an electric motor is provided to generate the driving force, acting on the rotary lever via a gearbox. Optionally, the gearbox includes a planetary gear stage with a sun gear, at least three planet gears, and a planet carrier. The planet carrier serves as the drive element.

[0030] According to one example, the rotary lever has a second lever segment that can be engaged with a pull-tab in a closing direction opposite to the opening direction of the rotary lever. The rotary latch has a stop against which the pull-tab rests, thus pulling the rotary latch from a pre-detent position towards the closed position.

[0031] According to one example, a rotatably mounted gear is provided for the rotatably mounted drive element, which serves as the output side of a gearbox and on which the drive contour is formed.

[0032] According to one example, a drive contour with at least one axially projecting tab is provided on the rotatably mounted gear on the side facing the drive lever.

[0033] According to one example, a rotatably held cam contour is provided which acts on the pawl via an opening lever in order to move the pawl from a blocking position to a release position.

[0034] As an option, the cam contour can be formed concentrically with the rotatably mounted drive element, for example, the rotary lever or the gear. In one example, the cam contour is formed on the drive element.

[0035] This results in a compact design, which is advantageous.

[0036] According to the invention, a vehicle lock module is also provided. The vehicle lock module comprises a vehicle lock according to one of the preceding examples and at least one user interface for operating the vehicle lock. The user interface is coupled to the vehicle lock.

[0037] According to the invention, a motor vehicle door module is also provided. The motor vehicle door module comprises a supporting structure of a motor vehicle door and a motor vehicle lock according to one of the preceding examples or a motor vehicle lock module according to the preceding example. The motor vehicle lock is held on the supporting structure.

[0038] According to the invention, a method for actuating a motor vehicle lock for a movable locking component is also provided. The method comprises the following steps:

[0039] Providing a drive lever that is movably held between a starting position and an extended position and that is used to raise the movable end component; wherein the drive lever is guided at a second end opposite a first end along a guide track between a first and a second position; wherein the drive lever has a longitudinal slot in the area between the first end and the second end, into which a fixed bearing pin engages to guide the drive lever; wherein the bearing pin and the longitudinal slot form a sliding pivot bearing for the drive lever; and wherein the guide track has a decreasing distance to the bearing pin from the first position to the second position, so that the force transmission ratio changes;

[0040] Applying a primary driving force to the second end; moving the second end towards the second position; and, as the first end moves towards the extended position, acting on the locking element in an opening direction of the movable closing component. In one example, the lock is initially closed in the main detent. Upon rotation in a first direction, the locking mechanism opens. A cam, for example, ensures that the locking pawl remains open during further rotation in the first direction. The opening lever pushes the closing pawl to the side, allowing the rotary latch to rotate freely past the pawl. The rotary lever makes contact with the guided dome of the drive lever, also called the push-out lever, and, upon further rotation in the first direction, moves it within its guide.The push-out lever (PO lever) now makes contact with the drive dome in the rotary latch and can move the rotary latch into the open position via this dome using force amplification. The push-out lever is guided in such a way that it first rotates around the rotary latch dome. In an intermediate position during the push-out process, it is designed so that, as long as the push-out lever is rotating around the rotary latch pin due to its guide, it drives the rotary latch along and rotates it into the open position. The push-out lever can generate a very large force, sufficient for opening an iced-over door (icebreaking) or for opening a door jammed after a crash. In this intermediate position during the push-out process, the push-out lever, guided in the reinforcing plate, also receives a translational movement within its guide on the rotary latch dome. The rotary latch is now almost fully open.The system is geometrically designed so that, as the movement progresses, the push-out lever makes contact with the locking bolt. The push-out lever now requires less force but travels a greater distance at a higher speed. The push-out process is then complete. The push-out lever is at its end stop. The reversing process then begins. The rotary lever is turned in the opposite direction and makes contact again with the guided pin in the push-out lever. In an intermediate position during the reversing process, the opening lever is returned to its starting position by a spring as it continues to rotate. The pawl is released and can rest on the back of the rotary latch. The closing pawl also returns to its starting position via a spring. The reversing process is complete. The locking mechanism is open and can be closed from this position using the pre-latch or directly in the main latch.Provided the lock is first closed in the pre-latch position, the closing action can be activated. The locking mechanism is, for example, closed in the pre-latch position. The lever is turned in the second direction, engaging the closing pawl. The closing pawl makes contact with the rotary latch. The closing action is complete, and the rotary latch is, for example, in its overtravel position. After closing, the lever reverses, for example, and the lock is closed in the main latch position.

[0041] According to one aspect, an opening actuator is provided that acts directly on the locking element to slightly open the movable closing component, i.e., to open it a crack. The actuator is operated via a geared lever in which the transmission ratio changes during opening: initially, a large amount of force is applied for a small distance; this changes to less force and a greater distance. The actuator is located directly within the lock.

[0042] According to one aspect, the standard functions of the locking mechanism, i.e., the rotary latch and pawl, are not affected by the drive lever.

[0070] Fig. 1a schematically shows an example of a motor vehicle lock 10 for a movable locking component. The motor vehicle lock 10 has a locking mechanism 12 with a pawl 14 and a rotary latch 16 for holding a locking element 18. The motor vehicle lock 10 also has an actuating lever 20. The actuating lever 20 is movably held between a neutral position (see, for example, Fig. 1a) and an extended position (see, for example, Fig. 11). To raise the movable locking component, the actuating lever 20 is designed so that, when moved towards the extended position, its first end 22 acts on the locking element 18 in a raising direction of the movable locking component.The drive lever 20 is guided at a second end 24 opposite the first end 22 along a guide track 26 between a first and a second position and can be subjected to a drive force in the direction of the second position. The drive lever 20 has a longitudinal slot 28 in the area between the first end 22 and the second end 24, into which a fixed bearing pin 30 engages to guide the drive lever 20. The bearing pin 30 and the longitudinal slot 28 form a sliding pivot bearing for the drive lever 20. The guide track 26 has a decreasing distance 32 from the bearing pin 30 from the first position to the second position, so that the force transmission ratio changes.

[0071] In Fig. 1a, an inlet opening 32 for the locking element 18 is indicated with two inlet chamfers 34. The locking element 18 is received in a receptacle 36 of the rotary latch 16. The rotary latch is shown in a rotational position engaging behind the locking element 18.

[0072] In one example, the rotary latch 16 is pivotally mounted between an open and a closed position: The rotary latch 16 is designed to hold the locking element 18 in the closed position and to release the locking element 18 in the open position. The locking pawl 14 is movably mounted at least between a release position and a first locking position. In the first locking position, the locking pawl 14 prevents the rotary latch 16 from moving towards the open position, and in the release position, the rotary latch 16 is movable in the direction of the open position. The direction of movement of the movable locking component can also be described as the direction away from the rotary latch 16.

[0073] The closed position of the rotary latch 16 can also be referred to as the main detent.

[0074] In one example, a second closing position is provided, which can be described as a pre-latch. The rotary latch 16 is also blocked by the locking pawl 14 in the second closing position. The position of the locking pawl 14 can then be described as the second blocking position.

[0075] The blocking position of the pawl 14 can also be referred to as the locking position or locking position.

[0076] The pawl 14, for example, has a locking lug 38 for bearing against a counterpart of the rotary latch 16. The rotary latch 16, for example, has a first stop 40 for bearing the locking lug 38 for the preliminary latch, and a second stop 42 for bearing the locking lug 38 for the main latch.

[0077] The pawl 14 is rotatably mounted about a second pivot bearing 46. The pawl 14 can be moved (referring to the illustration) clockwise into the release position and counterclockwise into the locking position.

[0078] The rotary latch 16 is rotatably mounted about a first pivot bearing 44. The rotary latch 16 can be moved (with reference to the illustration) clockwise into the open position and counterclockwise into the closed position.

[0079] In Fig. 1a, the locking pawl 14 is shown in its released position. The rotary latch 16 can rotate in the direction of the open position (clockwise in the illustration).

[0080] Fig. 1a shows a first movement state of the motor vehicle lock 10. The locking element 18 is held. The drive lever 20 is in its starting position.

[0081] The drive lever 20 drives the movable closing component, for example, a vehicle door. The drive lever 20 forms, for example, a door drive. The opening action can also be described as a push-out movement. Another term is door presenting. The opening action can also fulfill the so-called icebreaker function.

[0082] The term "drive lever" refers to a power transmission element in the form of a lever that can be rotated and pivoted to cause the door to open.

[0083] The term "open position" refers to the position of the rotary latch 16 in which the locking element is no longer held and the door can be opened.

[0084] The term "closed position" refers to the position of the rotary latch 16 in which the locking element is held and the door cannot be opened.

[0085] The term "release position" refers to the position of the pawl 14 in which the rotary latch 16 is not blocked by the pawl 14, but is released.

[0086] The term "blocking position" refers to the position of the pawl 14 in which the rotary latch 16 is blocked by the pawl 14 and is not released.

[0087] The term "starting position" refers to the position of the drive lever at the beginning or before the start of the activation.

[0088] The term "exit position" refers to the position of the drive lever when the vehicle door is opened as far as it can go.

[0089] The term "first end" refers to the distal end, i.e., the extending and force-emitting end.

[0090] The term "guide track" refers to linear guidance along a track-shaped path. The guide track defines the distance to be traveled and the respective position of the drive lever 20. The guide track can be straight or curved.

[0091] Fig. 1a (see also Fig. 4) shows, as an option, that the guide track is designed as an elongated guide slot 48. The drive lever 20 has a guide pin 50 at its second end 24, which engages in the guide slot 48.

[0092] The guide slot forms a lever guide track.

[0093] The term "elongated" refers to an elongated shape. The term "guide pin" refers to a protruding area that can be guided in or along the guide track.

[0094] Figure 1a shows, as a further option, that the guide track has a curvature 52. As an option, the curvature 52 is designed to be aligned with the bearing pin 30.

[0095] The term "curvature" refers to a deviation from a straight line. For example, curvature can be increasing, meaning a decreasing radius of curvature, or decreasing, meaning an increasing radius of curvature. In one example, the guide rail has different radii of curvature.

[0096] Figure 1a shows a further option in which the rotary latch 16 is pivotally held on a rotary latch bearing 54. The bearing pin 30 is concentric with the rotary latch bearing 54.

[0097] The lifting drive is mounted on the bearing bolt 30. The bearing bolt 30 can also be referred to as the rotary latch bolt or rotary latch dome.

[0098] The term "concentric" refers to an aligned, identical arrangement of the respective rotation or pivot axes.

[0099] In Fig. 1a, a further option is shown in that the drive lever 20 has a projecting stop 56 at the first end 22 for bearing against the closing element 18. The projecting stop 56 is arranged on the drive lever 20 on one side of the movable pivot bearing that is opposite a force application point at the second end 24.

[0100] The term "protruding" refers to an area that projects beyond a base. The term "stop" refers to a contact surface for the locking element 18.

[0101] Figure 1a shows, as an option, that the rotary latch 16 has a drive pin 58 and that the drive lever 20 bears against the drive pin 58 when the drive lever 20 is moved towards the extended position, in order to move the rotary latch 16 towards the open position by means of the drive lever 20, so that in a first opening phase the rotary latch 16 acts on the closing element 18 in the opening direction. As an option, it is provided that in a second opening phase the projecting stop 56 acts on the closing element 18.

[0102] The term "carrying dome" refers to a projection or bolt designed so that the drive lever 20 rests against it in order to transmit the movement, i.e., to carry the rotary latch 16 along during the rotary movement.

[0103] For example, the transition from the first setup phase to the second setup phase is seamless.

[0104] In a first variant, the drive lever is designed without a drive dome; here, the setup is carried out entirely via the drive lever, for example via the protruding stop on the drive lever, which rests against the locking element for setup.

[0105] In a second variant, the drive lever is designed with a drive dome; here, the initial setup is achieved via the rotary latch, which acts on the locking element, i.e., which rests against the locking element during the first setup phase. Since the rotary latch can only provide a limited range of motion for setup, the second setup phase is achieved via the drive lever, for example, via the projecting stop on the drive lever, which rests against the locking element during setup.

[0106] In a third variant, the drive lever is also designed with a drive dome; in this case, the initial setup is achieved via the rotary latch and the drive lever. The rotary latch acts on the locking element, meaning that during the first setup phase, the rotary latch rests against the locking element, parallel to the drive lever, which, for example, rests against the drive lever via the projecting stop.

[0107] The application of the drive lever 20 to the locking element 18 via the rotary latch 16 during the initial setup phase, i.e., at the beginning of the setup process, offers the advantage that the setup force can be introduced via existing components that are already adequately dimensioned for this task. The rotary latch 16 is designed to securely hold the locking element 18; the force initially required for setup can therefore be transmitted just as reliably. The subsequent setup, i.e., the second phase, can then be carried out via the drive lever 20. Since the forces are lower in the second phase, the drive lever 20 does not need to be particularly robust. Because the drive lever 20 is arranged, so to speak, parallel to the rotary latch 16, the force applied to the locking element 18 is only slightly offset from the force applied by the rotary latch 16.However, since the force transmitted by the drive lever 20 is less, the force can also be transmitted to the locking element 18 in an edge area.

[0108] The engagement of the locking element 18 by the rotary latch 16 at the beginning of the setup process also has the advantage of reducing the relative movement between the locking element 18 and the drive lever 20; a portion of this movement is, so to speak, converted into the relative movement between the locking element 18 and the rotary latch 16. This reduces scratches and wear on the locking element 18.

[0109] Compared to opening solely via the rotary latch 16, the opening range is extended due to the drive lever 20 and is not limited to the dimensions of the rotary latch 16. This allows the door to be presented with a movement of, for example, >30 mm.

[0110] Furthermore, the action of the drive lever 20 on the rotary latch 16 also means a more favorable lever geometry.

[0111] According to one aspect, the push-out movement initially occurs via the rotary latch 16 with its corresponding advantages and is then completed with the actual push-out lever formed by the drive lever 20. The kinematics can be adjusted to enable a smooth transfer and movement.

[0112] According to one aspect, a powerful push-out movement from the main latch is provided via the wide, encased rotary latch 16, which can also be referred to as a rotary bolt, with good force engagement on the locking element 18, for example, a locking bar, without damaging it. Once the open position of the rotary latch 16 is almost reached, the lever takes over and pushes the locking element 18 further out of the lock than would be possible with the rotary latch 16 alone.

[0113] The locking element 18 is, for example, a locking wedge, a locking bar or a locking bolt.

[0114] The push-out movement is achieved via the rotary latch 16 and can also be used for

[0115] It can be used to open jammed doors. The push-out lever, i.e., the drive lever 20, transmits its force to the rotary latch 16. The lever, for example, has no contact with the locking element 20, such as the locking bar.

[0116] The rotary latch 16 can no longer extend the locking bolt further out of the lock at a certain point. The lever then takes over. At this point, for example, any ice buildup will have already broken, and the door only needs to be "presented" with comparatively little force. In its final position, the door will be open approximately 50 mm.

[0117] According to one aspect, the drive lever 20 and the rotary latch 16 provide a vehicle lock with push-out and OBW functions (see below). Push-out function refers to opening the vehicle door; OBW (open-by-wire) refers to the electrical opening of a vehicle lock.

[0118] Fig. 1b shows the vehicle lock 10 from Fig. 1a in a state of motion in which the drive lever 20 has already slightly rotated the rotary latch 16 via the drive dome 58. The locking element 18 is already pressed slightly to the left, i.e., in the opening direction, by the rotary latch 16. The locking element 18 is still held in the rotary latch 16. Due to the lever ratio, a large force can be transmitted with a small distance.

[0119] Fig. 1c shows the vehicle lock 10 in a state of motion in which the drive lever 20 has already rotated the rotary latch 16 a little further via the drive pin 58. The locking element 18 is pressed even further to the left by the rotary latch 16, i.e., in the opening direction. The locking element 18 is no longer held by the rotary latch 16.

[0120] Fig. 1d shows the vehicle lock 10 in a state of movement in which the drive lever 20 has rotated the rotary latch 16 a little further via the drive pin 58. However, the further pressing of the locking element 18 now occurs in a so-called second phase by the drive lever 20, or rather by the projecting stop 56 of the drive lever 20. The locking element 18 is no longer held by the rotary latch 16. Due to the changing lever ratio, an increasingly smaller force can be transmitted over an increasingly larger distance. Fig. 1e shows the vehicle lock 10 in a state of movement in which the drive lever 20 has not rotated the rotary latch 16 any further, or only very slightly further, via the drive pin 58. The locking element 18 is still no longer held by the rotary latch 16.The locking element 18 is pushed further to the left by the drive lever 20; the movable closing element, not shown, is now in an upright position.

[0121] Fig. 2 shows another example of a motor vehicle lock in a perspective view. An electric motor 60, oriented transversely to the plane of the locking mechanism, is shown as the drive. A worm gear segment 62 mounted on a motor shaft drives a worm wheel 64. This either acts directly on the drive lever 20, or a gear arrangement is provided.

[0122] Fig. 3 shows a section of the example from Fig. 2. The drive lever 20 protrudes here through an opening 66 in a housing 68 and has pressed the closing element 18 into the extended position in which the movable closing component is open and can be moved manually by the user.

[0123] Fig. 4 shows another example of the motor vehicle lock 10 in a perspective view with a drive 70 comprising an electric motor 72 and a gearbox 74. The electric motor 72 is aligned with its motor shaft, for example, in a plane parallel to the locking mechanism 12. In Fig. 4, the locking element 18 is held by the rotary latch 16, which is blocked by the pawl 14.

[0124] Fig. 5 shows a top view of the example from Fig. 4.

[0125] According to an example not shown in detail, a rotatably mounted drive element is provided, upon which a drive force acts. In an opening direction, the rotatably mounted drive element acts on the guide pin to move the drive lever towards the extended position.

[0126] According to one example (not shown in detail), the driving force acts in a first direction on the rotatably mounted drive element to move the drive element in the opening direction. According to another example (not shown in detail), the rotatably mounted drive element acts in a closing direction on the guide pin to move the drive lever towards the starting position.

[0127] According to an example (not shown in detail), the driving force acts in a second direction on the rotatably mounted drive element in order to move the drive element in the closing direction.

[0128] According to another example (not shown in detail), the rotatably mounted drive element acts on a release lever in the opening direction before acting on the guide pin to release the pawl of the locking mechanism.

[0129] For example, the rotatably mounted drive element first releases the locking mechanism, i.e., the locking pawl, and then, with the drive lever, acts on the locking element, i.e., pushes the locking element out of the lock and thus opens the door at least a crack. With regard to the actual opening, the drive, via the rotatably mounted drive element, therefore initially has a free stroke.

[0130] To ensure the free stroke, for example, a distance is provided between a first stop or projection and a second stop or projection in which the drive element does not act on the guide pin.

[0131] In one variant, the idle stroke is also depicted in the reverse direction: When the closing element is in its maximum extended position, i.e., in its fully extended position, the direction of rotation of the rotatably mounted drive element is reversed. The drive element then travels, for example, the specified distance until it engages with the other stop or projection. Upon contact with this, the drive lever is then retracted.

[0132] In one variant, the drive element also rotates the rotary latch towards the closed position. Once the closing element enters the engagement range of the rotary latch, it can be pulled shut.

[0133] In one variant, pushing or setting up is provided together with pulling, in combination with the electric opening of the lock.

[0134] In one version, pushing or tilting the lock is done in conjunction with pulling it closed, but without combining it with the electric opening of the lock. The lock is then opened in another way, for example manually or by a separate drive mechanism.

[0135] In another variant, pushing or setting up is provided without pulling, but in combination with the electric opening of the lock.

[0136] In yet another variation, the lock is opened or raised without being pulled shut, and without being combined with the electric opening mechanism. In this variation, the lock is also opened differently, for example manually or by a separate drive.

[0137] According to one example, a rotatably mounted drive element is provided, upon which a drive force acts. In an opening direction, the rotatably mounted drive element acts on the guide pin to move the drive lever towards the extended position.

[0138] According to one example, the driving force acts in a first direction on the rotatably mounted drive element in order to move the drive element in the opening direction.

[0139] According to one example, the rotatably mounted drive element acts in a closing direction of the drive element on the guide pin to move the drive lever in the direction of the starting position.

[0140] According to one example, the driving force acts in a second direction on the rotatably mounted drive element in order to move the drive element in the closing direction.

[0141] According to one example, the rotatably mounted drive element, in the opening direction, acts on a release lever to release the pawl of the locking mechanism before acting on the guide pin.

[0142] According to one example, the rotatably mounted drive element has a drive contour with at least one projection on a side facing the drive lever. In an opening direction of the drive element, the drive contour rests against the guide pin to move the drive lever.

[0143] For example, the drive contour has a first projection that rests against the guide pin in the opening direction of the drive element to move the drive lever towards the extended position. Optionally, the drive contour also has a second projection that rests against the guide pin in the closing direction of the drive element to move the drive lever towards the initial position.

[0144] The projections are designed, for example, as protruding tabs or stops.

[0145] For power transmission, a rotatably mounted rotary lever 80 is provided as an option for the rotatably mounted drive element, which is also explained in more detail in connection with the following figures. The rotary lever 80 has a first lever segment 82 (see Fig. 12d) which, in an opening direction (clockwise in the figure) of the rotary lever 80, bears against the guide pin 50 to move the drive lever 20 in the direction of the extension position.

[0146] The term "lever segment" refers to an area of ​​the rotary lever 80 that acts as a lever.

[0147] The term “opening direction” refers to a direction of movement of the rotary lever 80, in which the lock is opened, for example, and the door is opened at least partially.

[0148] In one option, the rotary lever has an additional lever segment that rests against the guide pin in a closing direction of the rotary lever to move the drive lever towards the starting position.

[0149] As a further option, Fig. 4 shows that the driving force acts on a rotatably held drive element 90, which transmits the driving force to the rotary lever 80.

[0150] As an option, it is provided that the drive element 90 is rotatably held concentrically with the rotary lever 80 and has a drive projection 92 which engages axially in a receptacle 84 of the rotary lever 80 (see Fig. 6 and Fig. 8).

[0151] The term "carrying element" refers to a movable component that can be subjected to a driving force in order to then carry another component along during the movement, i.e., to transmit the movement.

[0152] The term "drive projection" refers to a projection designed to interact with the rotary lever 80 to transmit the motion. For example, the receptacle 84 is a concentrically arranged curved slot, and the drive projection 92 is a correspondingly curved, concentrically extending projection that completely fills the receptacle 84.

[0153] One option provides that the drive projection 92, or the receptacle 84, is located relatively far inwards at the pivot point of the lever. This has the advantage that a dry / wet area separation located at this point can be more easily designed due to the smaller diameter of the penetration of the separation.

[0154] An optional drive unit is available that is integrated into the housing of the vehicle lock. This drive unit could be, for example, a door lock drive.

[0155] Another option is a drive unit that is attached to a supporting structure of the vehicle lock, for example a housing.

[0156] As a further option, a drive is provided which is arranged separately and is connected to the vehicle lock via a power transmission element, for example via a linkage or a Bowden cable connection.

[0157] In one example, the drive is a motor, for example an electric motor. In another example, the drive is a hydraulically or pneumatically driven electric motor.

[0158] In one option, the drive element 90 is positively connected to the rotary lever 80.

[0159] In another option, the rotary lever 80 is formed in one piece with the drive element 90.

[0160] The concentric arrangement of the drive, or rather the power output from the gearbox to the drive element 90 and the rotary lever 80, facilitates the transmission of the drive force.

[0161] As an option, Fig. 4 shows that the electric motor 72 is provided to generate the driving force, which acts on the rotary lever 80 via the gearbox 74.

[0162] As a further option, the transmission 74 is provided to have a planetary gear stage 76 with a sun gear 78, at least three planet gears and a planet carrier 79. The planet carrier 79 is designed as the drive element 90.

[0163] In another example, not shown in detail, two planetary stages are formed.

[0164] The gearbox 74, for example, has a worm shaft 77 which meshes with a worm gear 75. The worm gear 75 is, for example, configured as the sun gear 78 of the planetary gear set, or the planetary gear stage 76.

[0165] As an option, it is provided that the worm wheel 75 is designed concentrically to the drive element 90 and is in engagement with the drive element 90, i.e. the worm wheel 75 is mechanically connected to the drive element 90.

[0166] As a further, alternative option, the worm gear 75 is provided for in mesh with another gear. This other gear is, for example, concentric to the drive element 90 and meshes with the drive element 90, i.e., the other gear is mechanically connected to the drive element 90.

[0167] As a further alternative option, the worm gear 75 is provided for in mesh with a gear that is designed as the sun gear of the planetary gear stage. The gear, i.e., the sun gear, is, for example, concentric with the drive element 90. The sun gear meshes via the planet gears with the planet carrier, which in turn is in mesh with the drive element 90; that is, the gear is mechanically connected to the drive element 90.

[0168] As an additional option, the rotary lever 80 is shown to have a second lever segment 86 which can be engaged with a pull-lock pawl 100 in a closing direction opposite to the opening direction (in the figure, counterclockwise). The rotary latch 16 has a stop 102 for the pull-lock pawl 100 to bear against, or a protrusion 104 of the pull-lock pawl 100 to pull the rotary latch 16 from a pre-latched or open position towards the closed position. For example, a pull-lock lever 106 is provided with the pull-lock pawl 100 projecting from it. The term "closing direction" refers to the direction of movement of the rotary lever 80 in which, for example, the door is closed and the door lock is engaged.

[0169] The term "stop" refers to a surface or edge against which the pull latch 100 can rest for force transmission.

[0170] The motor vehicle lock 10 can therefore be equipped with an integrated closing aid.

[0171] The rotary lever 80 can also be referred to as a multi-function lever.

[0172] The rotary lever 80 can also be referred to as a push-out lever. The guide contour of the push-out lever can be assigned various functions. For example, from the initial position, the locking mechanism can first be opened (OBW) in one direction, followed by the push-out movement. In another direction, various functions can be implemented from the initial position, depending on requirements, such as closing (ZZH), central locking (ZV), and anti-theft protection (DS) (see also Fig. 13).

[0173] Regarding functions such as central locking and dual-clutch locking, the function can be designed so that either the push-out lever, i.e., the drive lever 20, or the associated control wheel that moves the push-out lever, activates the function and remains in that position, or returns to its initial position after activation. In the latter case, the mechanical deactivation of the function (central locking, dual-clutch locking) can occur, for example, during the overhead line (OBW) process.

[0174] Figure 4 shows a further option: a rotatably mounted cam contour 110 is provided, which acts on the pawl 14 via an opening lever 112 to move the pawl 14 from the locked position to the released position. Optionally, the cam contour 110 is designed concentrically with the rotatably mounted drive element, for example, the rotary lever 80.

[0175] In the example with the rotary lever, the cam contour is arranged, for example, on a side facing the drive lever.

[0176] The term "cam contour" refers to a contour with at least one cam, for example, a projection rising from a base surface to engage with the opening lever. This at least one cam extends continuously, for example.

[0177] As an option, the cam contour 110 is provided for on the drive element 90.

[0178] The cam profile can also be referred to as an open-by-wire cam. The opening lever can be referred to as a release lever.

[0179] Fig. 6 shows the drive element 90 for transmitting a drive force from a motor. As mentioned, the drive element 90 also serves to activate the opening function. The drive element 90 can also be referred to as a multi-function wheel.

[0180] The vehicle lock 10 is therefore optionally equipped with an integrated opening function for electric opening. Electric opening is also known as open-by-wire (OBW).

[0181] One option provides the integrated opening function without the integrated closing aid.

[0182] Another option provides the integrated closing aid without the integrated opening function.

[0183] In yet another option, the integrated opening function and the integrated closing aid are combined.

[0184] As an option, the opening lever can pivot the closing lever to the side when the locking pawl is pivoted into the release position. The closing lever is, in effect, pivoted to the side. This also allows for the interruption of a closing process. For example, an opening process of the movable closing component can be initiated by an inside handle, and any simultaneous closing process of the movable closing component can be interrupted by operating the inside handle.

[0185] In another example, the cam contour is formed on the rotary lever 80.

[0186] In one variant, neither the option of the opening lever 112 nor the option of closing using the closing latch 100 is provided. In another variant, the option of closing using the closing latch 100 is provided without the option of the opening lever 112.

[0187] In a further variant, the option of the opening lever 112 is provided without the option of closing using the closing latch 100.

[0188] In an additional variant, both the option of the opening lever 112 and the option of closing using the closing latch 100 are provided.

[0189] Fig. 7 shows the vehicle lock from Fig. 5 without the motor, and of the transmission only the drive element, in a top view. The locking element 18 is held by the rotary latch 14; the drive lever 20 is in a starting position.

[0190] Fig. 8 shows a perspective view of the example from Fig. 7. The rotary lever 80 is held on a bearing journal 114, on which other movable components of the transmission are also movably mounted. The bearing journal 114 is attached to a stationary housing structure, for example, a support plate 116. In the illustration, the rotary lever 80 is arranged above the support plate 116, and the drive lever 20 is located below the support plate 116. The guide pin 50 projects from below into, or through, the guide slot 48.

[0191] Fig. 9 shows a side view of the example from Fig. 7, viewed from the right (relative to Fig. 7).

[0192] Fig. 10 shows another perspective view of the example from Fig. 7. The drive lever 20 is shown in an end position in which the locking element 18 is pushed out of the area of ​​the rotary latch 16 by the drive lever 20. The locking element 18 is no longer held by the rotary latch 14.

[0193] Fig. 11a shows, from a different perspective, the example from Fig. 7 in a state of motion where the locking element 18 is held by the rotary latch 16. The drive lever 20 is shown in its starting position.

[0194] Fig. 11b shows the example from Fig. 10 from a different perspective in a further state of movement, in which the locking element is released and the door is pushed open. Fig. 12a shows the example from Fig. 7 in a top view in a state of movement in which the locking element 18 is held by the rotary latch 16. The drive lever 20 is shown in its initial position.

[0195] Fig. 12b shows the example from Fig. 12a in a state of motion in which the cam contour 110 has moved the opening lever 112, which acts directly or indirectly on the pawl 14 and unlocks it. Simultaneously, the opening lever 112 pushes the closing lever to the side so that the rotary latch 16 can move freely past the closing pawl. The rotary lever 80 comes into contact with the guided dome of the setting lever, i.e., the drive lever 20, and will move in its guide with further clockwise rotation.

[0196] Fig. 12c shows the example from Fig. 12b, but without the opening lever 112 and without the drive element 90.

[0197] Fig. 12d shows the example from Fig. 12a in a state of motion in which the drive lever 20 comes into contact with the drive pin of the rotary latch 16; the drive lever 20 can move the rotary latch 16 into the open position via this dome with force transmission. The drive lever 20 is guided such that it first rotates around the rotary latch dome.

[0198] Fig. 12e shows the example from Fig. 12a in an intermediate position during the setup process. As long as the drive lever 20 rotates around the rotary latch dome due to its guide, it engages the rotary latch and rotates it into the open position. The drive lever 20 can develop a very large force in this process.

[0199] Fig. 12f shows the example from Fig. 12a in a further intermediate position during the setup process. The guide causes the drive lever 20 to also move with a translational vector component.

[0200] Fig. 12g shows the example from Fig. 12a in a further state of motion, in which the rotary latch 16 is almost completely open. The drive lever 20 is now in contact with the locking element 16. Although the drive lever 20 now exerts less force, the opening action occurs at a higher speed. Fig. 12h shows the example from Fig. 12a in a state of motion in which the opening action is complete. The drive lever 20 is in its fully extended position, i.e., at its stop.

[0201] Fig. 12i shows the example from Fig. 12a at the beginning of a reversing process.

[0202] The rotary lever 80 is turned in the opposite direction, i.e., counterclockwise. The rotary lever 80 now comes back into contact with the guided dome on the drive lever 20.

[0203] Fig. 12j shows the example from Fig. 12a in an intermediate position of the reversing process. The rotary lever 80 is returned by a spring. The pawl 14 is released and can rest on the rotary latch 16. The closing pawl also rotates back to its initial position by spring action (see Fig. 12k).

[0204] Fig. 12k shows the example from Fig. 12a in a position where the reversing process is complete. The locking mechanism 12 is open, and the locking element 18 can be inserted, allowing the locking mechanism 12 to be moved into the pre-latch position or directly into the main latch position. For example, the closing process can be activated in the pre-latch position, as explained below.

[0205] Fig. 121 shows the example from Fig. 12a in a state of motion in which the locking mechanism 12 is in the pre-latch position.

[0206] Fig. 12m shows the example from Fig. 12a in a further state of motion, in which the rotary lever 80 is rotated counterclockwise. It engages the closing lever with the closing pawl. The closing pawl comes into contact with the rotary latch 16.

[0207] Fig. 12n shows the example from Fig. 12a in a state of motion in which the closing process is complete. The rotary latch 16 is in its overstroke.

[0208] Fig. 12o shows the example from Fig. 12a in a state of motion in which a reversal has occurred after tightening. The lock is closed in the main detent.

[0209] Fig. 13 shows an example of a vehicle lock where the drive provides a triple function: opening, unlocking, and closing. A first arrow 120 indicates the first function, opening. This is achieved via a first movement range 122 along the guide track. A second arrow 124 indicates the second function, opening the lock using the drive. This is achieved via a second movement range 126 along the guide track, but in the opposite direction to opening. A third arrow 128 indicates the third function, closing using the drive. This is achieved via a third movement range 130 along the guide track, but also in the opposite direction to opening.

[0210] Fig. 14a shows the vehicle lock from Fig. 13 in a first movement position, in which the locking element 18 is held, but the rotary latch 16 is released. For example, a maximum opening force of approximately 500 to 1000 N is provided, which is indicated by a first arrow 132.

[0211] Fig. 14b shows the vehicle lock from Fig. 14a in a second movement position, in which the locking element 18 is released and the door is pushed open. For example, a total travel of 40 to 50 mm is provided, which is indicated by a second arrow 134.

[0212] Fig. 15 shows another example 200 of the motor vehicle lock 10 in a top view. A rotatably mounted gear 202 is provided for the rotatably mounted drive element, which serves as the output side of a transmission and on which the drive contour is formed in the form of a first tab 204 and a second tab 206. The tabs are arranged on the gear on the side facing away from the figure (as viewed from the figure) and are therefore shown with dashed lines.

[0213] In comparison to the described example of the motor vehicle lock 10 with the rotary lever 80, the gear 202 is provided instead of the rotary lever.

[0214] When the gear 202 is driven clockwise, the first tab 204 rests against the guide pin 50 in order to move the drive lever 20 in the direction of the extension position.

[0215] The second tab 206 then rests against the guide pin 50 when the gear 202 is driven counterclockwise, thus moving the drive lever 20 towards its starting position. In an alternative embodiment, a rotatably mounted lever is provided for the rotatably mounted drive element, which is connected to a gearbox and on which the drive contour is formed.

[0216] In the example with the gear 202 and the projections 204, 206, a cam contour 208 is arranged, for example, on the side facing away from the drive lever, i.e., on the other side of the projections 204, 206. (In Fig. 15, this is the side facing the viewer.) A pivotally mounted release lever 210 rests against the cam contour 208 and acts on the pawl 14 to release it before the drive lever 20 is actuated, i.e., moved. When the pawl 14 is released, the rotary latch 16 can be moved to release the locking element 18, so that the locking element can also be moved by the drive lever to open the vehicle door.

[0217] In one example, the cam contour 208 is formed concentrically with the rotatably mounted gear 202.

[0218] The cam contour 208, for example, is designed similarly to the contour in Fig. 6.

[0219] Fig. 16 shows the example from Fig. 15 in a side view.

[0220] Fig. 17 shows the example from Fig. 15 in a perspective view.

[0221] Figs. 18a, 18b, 18c, 18d, 18e, 18f, 18g, 18h and 18i show the example from Fig. 15 in a top view in different states of motion.

[0222] In the example shown in Fig. 18a-i, the drive element, which is designed, for example, as the gear 202, rotates by approximately 50°-60°, then actuates the opening lever 210 and thus opens the pawl 14. The push-out drive in the drive element then reaches the guided dome of the push-out lever, i.e., the drive lever 20, and can drive the drive lever 20 from this moment on.

[0223] The opening of the lock, i.e. the locking mechanism, and the setting up are done with a lever or drive element.

[0224] After installation, a sensor can, for example, initiate the resetting process. The sensor provides a signal indicating when the door is opened, i.e., when the user manually opens the door. The sensor can also provide a timeout signal. Once the resetting process is complete, meaning the reversing action is fully finished and the drive lever is back in its end position, the vehicle lock can be closed again as usual.

[0225] In Fig. 18a, the locking pawl 14 is engaged with the rotary latch 16 and blocks it. The release lever 210 is not yet activated.

[0226] In Fig. 18b, the release lever 210 is pivoted to the side by the cam contour 208 and has released the pawl 14. The gear 202 rotates clockwise. The first tab 204 acts on the guide pin 50, and the drive lever 20 is moved via this, thus introducing the input force. The drive lever 20 then transmits the force as output force to the locking bar 18.

[0227] In Fig. 18c, the first tab 204 continues to act on the guide pin 50. In this phase, the erection takes place with great force and a small distance.

[0228] Fig. 18d shows an intermediate position; the setup now requires less force, but is faster.

[0229] Fig. 18e shows another intermediate position; the locking bar is extended a little further.

[0230] Fig. 18f shows the final position of the opening process after a total stroke on the locking lever of, for example, approximately 50 mm.

[0231] Figure 18g shows the start of the reset process, for example, after a signal from a sensor. The gear 202 now rotates counterclockwise, i.e., back into its original position. Here, the second tab 206 acts on the guide pin 50. The drive lever 20 is retracted.

[0232] Fig. 18h shows an intermediate position; the locking lever 18 is no longer held.

[0233] In Fig. 18i, the reversing process is complete. The lock can now be closed by immersing the locking bolt 18 into the entry jaw of the lock.

[0234] Fig. 19 schematically shows an example of a motor vehicle lock module 300. The motor vehicle lock module 300 has an example of the motor vehicle lock 10 according to one of the preceding examples and at least one user interface 302 for actuating the motor vehicle lock 10. The user interface 302 is coupled to the motor vehicle lock 10, which is indicated in Fig. 19 by a dashed line 304.

[0235] The least one user interface 302 is, for example, an interior door handle, an exterior door handle, or a button or sensor connected to the vehicle lock. Actuation includes, for example, opening the locking mechanism, raising the movable closing component, or closing the movable closing component.

[0236] Fig. 20 schematically shows an example of a motor vehicle door module 400. The motor vehicle door module 400 has a support structure 402 for a motor vehicle door 404. In a first option, the motor vehicle door module 400 has an example of the motor vehicle lock 10 according to one of the preceding examples. In a second option, the motor vehicle door module 400 has an example of the motor vehicle lock module 300 according to one of the preceding examples. The motor vehicle lock 10 is held on the support structure 402.

[0237] The support structure 402 is designed, for example, as a mounting structure for other components in the vehicle door, such as window regulators, drives, speakers, or other functional components. The support structure 402 is, for example, a multifunctional bracket (MFB). The support structure 402 can also be a frame structure of the vehicle door.

[0238] In Fig. 20 a window area 406 and two hinges 408 are indicated.

[0239] In one option, the vehicle lock is provided on the movable end component and the locking element on the stationary body.

[0240] In a second option, the vehicle lock is located on the stationary body, and the locking element on the movable end component.

[0241] For example, a body module is provided that includes a motor vehicle body structure and a motor vehicle lock according to one of the preceding examples, or a motor vehicle lock module according to the preceding example. The motor vehicle lock is held to the body structure.

[0242] Fig. 21 shows an example of a method 500 for actuating a motor vehicle lock for a movable closing component. The method 500 comprises the following steps:

[0243] In a first step 502, a drive lever is provided which is movably held to position the movable end component between a starting position and an extended position. The drive lever is guided at a second end opposite a first end along a guide track between a first and a second position. The drive lever has a longitudinal slot in the area between the first and second ends, into which a fixed bearing pin engages to guide the drive lever. The bearing pin and the longitudinal slot form a sliding pivot bearing for the drive lever. The guide track has a decreasing distance to the bearing pin from the first position to the second position, so that the force transmission ratio changes.

[0247] The term "movable closing component" refers to a movable part of a motor vehicle that allows an opening or access point to be temporarily closed by closing the movable closing component and that allows the opening or access point to be temporarily made accessible by opening the movable closing component. The term "movable closing component" thus refers to a movable closure of a motor vehicle. Examples of movable closing components include a motor vehicle door, a motor vehicle hatch, a motor vehicle hood, or a loading hatch. A movable closing component comprises at least one of the following: motor vehicle doors, motor vehicle hatches, motor vehicle hoods, or loading hatches. Motor vehicle doors can, for example, be side-hinged doors, sliding doors, or upward-hinged doors or door segments.Vehicle hatches can be, for example, tailgates. Vehicle hoods can be, for example, engine compartment hoods, such as those located at the front of the vehicle. Vehicle hoods can also be front hoods used to close off storage compartments underneath. These front hoods are also called frunks (from the English: front trunk). Loading flaps can be, for example, hinged flaps located at the rear or on the side to provide access to a loading area or cargo bed. Loading flaps can also be called vehicle loading flaps. In connection with so-called pickup trucks, e.g., with an open cargo bed, loading flaps are also called drop gates. When the present invention refers to a vehicle door, this also includes the other forms of the movable closing component mentioned as examples.The term motor vehicle lock or door lock includes, for example, a lock for a motor vehicle door, a lock for a motor vehicle hatch, a lock for a motor vehicle hood, or a lock for a loading hatch.

[0248] The term "vehicle lock" refers to a lock on a vehicle door. The door lock, for example, holds a locking bar or bolt in a releasable position to keep the door closed.

[0249] The term "door lock actuator" refers to a drive mechanism for the locking system of a door lock. A door lock actuator can be, for example, an electric drive for opening the locking mechanism of a door lock. It can also be an electric drive for closing the rotary latch of a vehicle lock, thus enabling the door to be pulled shut. A door lock actuator can also be designed, for example, as a door closing aid.

[0250] The term "door drive" refers to a mechanism for moving a vehicle door, for example, to at least partially open or close it. A door drive can be, for example, a door presenter, also known as a push-out unit, which opens the door a crack. A door drive can also be a mechanism for fully opening a door, such as a tailgate. A door drive can also be a closing aid that pulls the door into the closed position, for example, against the pressure of the door seal. A door drive can be designed, for example, as a door presenter that pushes the door away from the vehicle body to open it a crack. A door drive can also act on a door stop to move the door relative to the vehicle body.
