[0001] Motor vehicle lock, especially motor vehicle door lock
[0002] Description:
[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 pawl, and with an electric motor drive which acts both on a release lever for electrically opening the locking mechanism and, for the most part, simultaneously acts on a security unit and interacts with an actuating element for this purpose.
[0004] The motor vehicle lock is preferably a motor vehicle door lock, although the motor vehicle lock does not necessarily have to be used in connection with or on a motor vehicle door; rather, other applications in or on the motor vehicle are also conceivable, for example on and in connection with a motor vehicle flap or the like. With such motor vehicle locks, and in particular motor vehicle door locks, the general aim is to equip the frequently used electric motor drive with as many functions as possible, since such electric motor drives are typically expensive to construct. For this reason, the intention is to implement as many functions as possible within such a motor vehicle door lock using a (single) electric motor drive.
[0005] In fact, the state of the art, according to WO 2019 / 076399 A1, for example, is such that the electric motor drive is equipped with a drive element that acts directly or indirectly on the locking mechanism. Furthermore, the drive element interacts with at least one other element depending on the position, whereby the other element is a coupling element of an additionally implemented mechanical actuating lever chain. This already provides a compact, cost-effective, and functionally efficient design.
[0006] The generic prior art according to WO 2021 / 115537 A1 uses the drive unit or electric motor drive to enable simultaneous locking and unlocking or opening of the locking mechanism. The locking unit generally prevents manual opening of the locking mechanism.
[0007] This provides a motor vehicle lock, and in particular a motor vehicle door lock, with a simplified design and fewer components than previous motor vehicle locks. Furthermore, a cost-effective and structurally simple solution is to be provided.
[0008] The state of the art has generally proven itself when it comes to implementing multiple functions with the help of the electric motor drive. In this context, it ensures the electrical opening of the locking mechanism and, for the most part, simultaneously transfers the safety unit to its "secured" position or, according to the generic teaching, enables simultaneous locking of the operating lever. However, further improvements compared to this generic state of the art are still possible and conceivable. For the structural implementation, the known teaching works together with both an actuating element and a control lever. The actuating element is equipped as a component of the electric motor drive. The operating lever can be engaged with the release lever using the control lever.
[0009] 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 the design effort is further reduced and a more compact structure is observed compared to the previous embodiment.
[0010] To solve this technical problem, a generic motor vehicle lock and in particular a motor vehicle door lock is characterized in that the actuating element, when the locking mechanism is electrically opened in the opening direction of the electric motor drive, transfers the security unit at least temporarily into its actuating position contrary to the initial position and, when reversing, preferably back into its initial position.
[0011] In this way, when the locking mechanism is electrically opened in the opening direction of the electric motor drive, the safety unit is at least temporarily moved to the set position. This set position differs from the initial position. For example, if the initial position is the "locked" position of the safety unit, the set position corresponds to the opposite "unlocked" position. The reverse procedure can also be used. In this case, the initial position may correspond to the "unlocked" position, whereas the opposite set position represents the "locked" position.
[0012] Such a procedure has the general advantage that, for example, in the case of a security unit designed as an anti-theft device or locking unit and typically in the initial position "theft-proof" or "locked," the electrical opening of the locking mechanism is associated with the security unit at least temporarily assuming the "theft-unlocked" or "unlocked" position, thus allowing trouble-free door opening. As soon as the electric motor drive is reversed from this position, the security unit in question preferably returns to its initial position or is moved to the initial position with the aid of the electric motor drive—specifically, and in the example described, to the "theft-proof" or "locked" position.
[0013] Comparable advantages are achieved if the security unit initially “unlocks” or “unlocks” its position as the starting position. or "unlocked" position and the electric motor drive is actuated in its opening direction. In this case, the actuating element actuated by the electric motor drive ensures that the security unit is at least temporarily transferred to its "secured" functional position or, in this specific example, to the "theft-proof" or "locked" functional position. This has the consequence that the security unit is "secured" during the electric motor opening process, so that if, for example, a manual handle is actuated by a user at the same time, any malfunctions or collisions within the vehicle lock with the electric motor drive are not observed.
[0014] As soon as the locking unit assumes its at least temporarily "secured" functional position, any additional operating lever chain for manually opening the locking mechanism is interrupted. This allows the actual electromotive opening process to proceed uninterrupted in both cases, preventing any malfunctions or collisions with levers of a mechanical operating lever chain from occurring during additional manual actuation. The additional and preferably implemented procedure, whereby the locking unit is returned to its original position when the electromotive drive is reversed, also ensures that a type of "memory effect" is observed.
[0015] This is because the vehicle lock is returned to the state it was in before the electrical opening was initiated. If the security unit performs the described temporary change of state from the initial position to the set position during the electrical opening of the locking mechanism, this change of state is generally uncritical, since the associated vehicle door will be opened anyway.
[0016] Additionally, it is advantageous for the electric motor drive to move the locking unit either to the starting position or the set position in its opposite opening direction. This means that in the opposite opening direction to the opening direction of the electric motor drive assumed in conjunction with the electrical opening of the locking mechanism, the locking unit can be moved to its desired position independently of the electric motor drive. This can be either the "unlocked" or "locked" position. This depends on which starting position was assumed in each case and the set position to which the locking unit is then moved.
[0017] This makes it easy to operate the safety unit as an electric child safety lock. This means that, for example, after an electric opening of the corresponding vehicle door, the electric motor drive can be used to move the safety unit or child safety lock to the desired position: "unlocked" or "child-unlocked," or "locked" or "child-resistant." This is because, after reversing the electric motor drive following such an electric opening, and thus with the vehicle door closed, the electric motor drive can be operated in the opposite direction.
[0018] In this counter-opening direction, the safety unit can be advantageously moved either to the starting position or the set position. In this case, moving to the starting position is generally not necessary, because the safety unit has already been moved back to its starting position during reversing. However, if this advantageous variant is not used, it is generally possible to move the safety unit to both basic functional positions in the counter-opening direction using the electric motor drive. This means that the electric motor drive
[0019] The drive can actuate the security unit in the sense of “secured” as well as in the sense of “unsecured” in the opposite opening direction in question and independently of an electrical opening process.
[0020] This reduces overall design effort because the electric motor drive is used as the sole drive, both for electrically opening the locking mechanism and for controlling and applying force to the safety unit. As described, this prevents any malfunctions. This represents the key advantage.
[0021] According to a further advantageous embodiment, the actuating element is generally equipped with a first control contour and a second control contour. The design is furthermore such that the first control contour at least temporarily applies pressure to the safety unit in the opening direction of the electric motor drive. In contrast, the second control contour, usually in the opposite opening direction, ensures that the safety unit is preferably permanently applied. This means that the second control contour generally provides permanent pressure to the safety unit, specifically in the opposite opening direction of the electric motor drive.
[0022] In most cases, both of the aforementioned control contours are connected to a common axis of the actuating element. In this case, both control contours can be connected together to one actuating lever. In this context, it has also proven effective if the first control contour of the actuating element is actuated by means of a first counter-contour of the drive and the second control contour of the actuating element is actuated by means of a further second counter-contour of the drive. The two counter-contours of the drive are generally arranged on the circumference of an output pulley as part of the drive. On the opposite side of the output pulley, in contrast, there is generally an actuating cam for actuating the release lever.
[0023] Furthermore, the design further includes a coupling element as a component of the actuating element. The coupling element is advantageously guided in a coupling recess of the security unit. The coupling element can be a coupling pin, which, when "engaged," ensures that two actuating levers are operatively connected to one another as components of an actuating lever chain. This ensures that a release lever is actuated via the two actuating levers, allowing the locking mechanism to be opened. To do this, the release lever typically acts on the pawl, lifting it from its locking engagement with the rotary latch.
[0024] If, however, the coupling element or coupling pin is in its "disengaged" functional position, the two operating levers are not operatively connected to each other, and applying pressure to the operating lever chain is ineffective. Consequently, the locking mechanism cannot be opened using the release lever in this case.
[0025] The result is a motor vehicle lock, and in particular a motor vehicle door lock, that is characterized by a particularly compact and functional design. This is primarily due to the fact that the electric motor drive is a single drive. With the help of this single electric motor drive, the locking mechanism can be electrically opened and the security unit can be activated. The security unit itself can be designed as an anti-theft device, a locking unit, or even a child safety device. Combinations are also conceivable.
[0026] In this context, the safety unit is particularly preferred as a child safety device or an electric child safety device. Because the electric motor drive allows The security unit or child safety lock in question can be selectively moved in the opposite opening direction to its two basic positions: "unlocked" or "child-unlocked" as well as "locked" or "child-resistant." In principle, the security unit can, of course, also be a locking unit or an anti-theft device.
[0027] All of this is achieved with a compact yet functional design, because the temporary change in state of the locking unit during electrical opening of the locking mechanism—first from the starting position to the opposite set position and then back to the starting position during reversing—is uncritical, as in this case the corresponding vehicle door is opened anyway. In fact, this approach corresponds to a kind of "ballpoint pen principle" in that the initial actuation using the electric motor drive moves the locking unit from the starting position to the set position, and then the next actuation using the electric motor drive (during reversing) returns the locking unit to the starting position. These are the key advantages.
[0028] The invention is explained in more detail below with reference to a drawing which merely represents an exemplary embodiment; in the drawings:
[0029] Fig.1 and 2 the motor vehicle lock according to the invention and in particular motor vehicle door lock in a front view (Fig. 1) and a rear view (Fig. 2), each reduced to the elements essential for the invention.
[0030] The figures show a motor vehicle lock, which according to the exemplary embodiment is a motor vehicle door lock. This has a locking mechanism 1, 2, only indicated in Fig. 1, made of
[0031] Essentially, the rotary latch 1 and the pawl 2. The locking mechanism 1, 2 is shown in the closed position in Fig. 1. Here, one can also see a release lever 3, which can be actuated by means of an electric motor drive 4, 5, 6, 7, 8.
[0032] For this purpose, the electric motor drive 4, 5, 6, 7, 8 has an output pulley 4 and an actuating cam 5 arranged on the output pulley 4, which can be seen in the front view according to Fig. 1. The output pulley 4 is rotated by means of an electric motor 8, which is only indicated. On the rear side of the output pulley 4, which can be seen in Fig. 2, a first counter contour 6 and a second counter contour 7 are then realized as components of the electric motor drive 4, 5, 6, 7, 8, which will be explained in more detail below.
[0033] As already explained, the electric motor drive 4, 5, 6, 7, 8 can initially act on the release lever 3 to electrically open the locking mechanism 1, 2. For this purpose, the electric motor drive 4, 5, 6, 7, 8 is actuated in an opening direction EÖ indicated in Fig. 1 in a clockwise direction represented here by an arrow. This has the result that the actuating cam 5, which is connected to the output disk 4 in the front view, is moved far enough that, with the help of the actuating cam 5, the release lever 3 is pivoted about its axis in the counterclockwise direction also indicated in Fig. 1. In this way, the release lever 3 can act on the pawl 2 with a release arm 3a, which is then lifted around its axis in a clockwise direction from the locking engagement with the rotary latch 1. As a result, the rotary latch 1 opens spring-assisted in the position shown in Fig.1 also rotates counterclockwise, releasing a locking bolt (not shown here). The corresponding vehicle door can then be opened.
[0034] In addition to the described electrical opening of the locking mechanism 1, 2, the electric motor drive 4, 5, 6, 7, 8 is also designed and able to simultaneously open a safety unit 14, 15, 16 For this purpose, the electric motor drive 4, 5, 6, 7, 8 can interact with an actuating element 9, 10, 11, 12, 13.
[0035] During the previously described electrical opening of the locking mechanism 1, 2 in the opening direction EÖ of the electric motor drive 4, 5, 6, 7, 8, the actuating element 9, 10, 11, 12, 13 transfers the safety unit 14, 15, 16 at least temporarily into its actuating position contrary to the starting position and, when the electric motor drive 4, 5, 6, 7, 8 is reversed, preferably back to its starting position.
[0036] To this end, the design is first of all such that the actuating element 9, 10, 11, 12, 13 has a coupling element 9 as a component. The coupling element 9 is a coupling pin 9, which is guided in a recess or coupling recess of an actuating lever 14 as a component of the securing unit 14, 15, 16, as can be seen in particular in Fig. 2. In addition to the actuating lever 14, a further actuating lever 15 is provided, both of which are mounted coaxially around a common axis 16 and together define the securing unit 14, 15, 16.
[0037] If the coupling element or the coupling pin 9 is in the "disengaged" position shown in solid lines in Fig. 2, then applying force to the actuating lever 15 about the common axis 16 in the counterclockwise direction indicated here results in the actuating lever 15 being unable to engage the actuating lever 14 because the coupling pin 9 is "disengaged." The "secured" functional position of the securing unit 14, 15, 16 formed in this way corresponds to this.
[0038] If, on the other hand, the coupling element or the coupling pin 9 takes the position indicated by dash-dotted lines in Fig. 2 within the coupling recess of the actuating lever 14 (“engaged”), the already described loading of the actuating lever 15 in the
[0039] Counterclockwise rotation means that both actuating levers 14, 15 are mechanically coupled to one another via the coupling pin 9 and consequently pivot together around the common axis 16 in the indicated counterclockwise direction. As a result, the two actuating levers 14, 15 are also able to pivot the release lever 3, which is mounted coaxially around the axis 16, counterclockwise, so that the pawl 2 is lifted from its locking engagement with the rotary latch 1, as already described in the introduction. For this purpose, the two actuating levers 14, 15 and the release lever 3 are mounted around the common axis 16.
[0040] The previously described securing unit 14, 15, 16 is acted upon as a whole by an actuating element 9, 10, 11, 12, 13. The coupling element or the coupling pin 9 represents a component of this actuating element 9, 10, 11, 12, 13. In addition, the actuating element 9, 10, 11, 12, 13 is then also equipped with an actuating lever 10 which has a first control contour 11 and a second control contour 12 at its end. In addition, a spring 13 is implemented which acts on the actuating lever 10 and which, according to the exemplary embodiment as shown in Fig. 2, ensures that the actuating lever 10 is pretensioned towards the “disengaged” position of the coupling element or coupling pin 9. In fact, the coupling element or the coupling pin 9 is connected to one end of the adjusting lever 10, whereas the two control contours 11, 12 are located at the other end and are arranged here.
[0041] The mode of operation is as follows. Starting from the closed position of the locking mechanism 1, 2 as shown in Fig. 1, the actuation of the electric motor drive 4, 5, 6, 7, 8 in the opening direction EÖ ensures that the pawl 2 is lifted from its locking engagement with the rotary latch 1 via the actuating cam 5 of the release lever 3. At the same time, the actuating element 9, 10, 11, 12, 13 ensures that the safety unit 14, 15, 16 is actuated. This corresponds specifically and as shown in Fig. 2 to the process that The first counter contour 6 on the output pulley 4 is approached or acted upon by the first control contour 11 as a component of the actuating element 9, 10, 11, 12, 13. This is because the opening direction EÖ in the front view of Fig. 1 corresponds to a clockwise movement and, accordingly, in the rear view of Fig. 2, to a counterclockwise movement.
[0042] This results in the coupling pin 9 being moved from its previously assumed "disengaged" position, pre-tensioned by the spring 13, to the "engaged" position. As a result, during the described electrical opening of the locking mechanism 1, 2 in the opening direction EÖ of the electric motor drive 4, 5, 6, 7, 8, the actuating element 9, 10, 11, 12, 13 is moved from the illustrated initial position "unlocked" of the safety unit 14, 15, 16 or "disengaged" of the coupling pin 9 into a contrary actuating position and consequently "locked" and "engaged" of the coupling pin 9.
[0043] If, based on this, the electric motor drive 4, 5, 6, 7, 8 is reversed, the locking unit 14, 15, 16 returns to its original position or is transferred to this "secured" initial position. This is because when the electric motor drive 4, 5, 6, 7, 8 is reversed, the coupling element or coupling pin 9 - acted upon by the spring 13 - again assumes its "disengaged" position. The change of state of the locking unit 14, 15, 16 described in this way, initially temporarily from the "secured" position to the "unsecured" position and after reversing back to the original "secured" position, is overall uncritical because the locking mechanism 1, 2 was opened with the help of the electric motor drive 4, 5, 6, 7, 8 and consequently the associated motor vehicle door is open.
[0044] If, for example, the motor vehicle door is in its closed state and the locking mechanism 1, 2 also assumes its closed state as shown in Fig.1, the electric motor drive 4, 5, 6, 7, 8 can selectively move the safety unit 14, 15, 16 in its opposite opening direction into the
[0045] The locking device 14, 15, 16 can be moved to the initial position or the set position, specifically to the "locked" or "unlocked" positions. Since, in the exemplary embodiment, the locking device 14, 15, 16 has already reached its "locked" position after reversing the electric motor drive 4, 5, 6, 7, 8, an additional approach to this position in the opposite opening direction is usually not necessary. Rather, starting from the position shown in Fig. 2, the locking device 14, 15, 16 can be moved to the "unlocked" position.
[0046] Corresponding to this is that the second control contour 12, as a component of the actuating element 9, 10, 11, 12, 13, preferably permanently acts upon the securing unit 14, 15, 16 in the counter-opening direction in question, i.e., clockwise in Fig. 2. This is ensured by the second counter-contour 7 of the electric motor drive 4, 5, 6, 7, 8, with the aid of which the second control contour 12 of the actuating element 9, 10, 11, 12, 13 is acted upon for this purpose.
[0047] This process specifically corresponds to the fact that the output pulley 4 is acted upon in the opposite opening direction of the electric motor drive 4, 5, 6, 7, 8, thus clockwise in the illustration according to Fig. 2. This results in the second counter contour 7 of the electric motor drive 4, 5, 6, 7, 8 acting upon the second control contour 12 of the actuating element 9, 10, 11, 12, 13. Since the 2nd control contour 12 is designed as a two-arm lever that can be pivoted about an axis and is articulated to the adjusting lever 10, the clockwise movement of the 2nd counter-contour 7 of the drive 4, 5, 6, 7, 8 results in the adjusting lever 10 being moved downwards against the force of the spring 13 via the 2nd control contour 12 and consequently the coupling pin 9 is "uncoupled" from its previously assumed position in the initial position and consequently "secured" of the securing unit 14, 15, 16 into the "coupled" position.As a result, the safety unit 14, 15, 16 then assumes its functional position “unlocked” according to the dash-dotted representation in Fig. 2.
[0048] As soon as the electric motor drive 4, 5, 6, 7, 8 is actuated in its opening direction EÖ, the 2nd counter contour 7 moves back and releases the 2nd control contour
[0049] 12 is released, so that the adjusting lever 10, acted upon by the spring 13, again moves upwards in the illustration in Fig. 2 and the coupling pin 9 or the coupling element 9 is accordingly "disengaged". As a result, the securing unit 14, 15, 16 once again goes into its "secured" position. However, the 1st counter contour 6 has not reached the 1st control contour 11 of the adjusting element 9, 10, 11, 12, 13. This is only the case when, in connection with the electrical opening of the locking mechanism 1, 2, the driven disk 4 has covered such a great distance that the actuating cam 5 reaches the release lever 3. In this case, the 1st Counter contour 6 of the electric motor drive 4, 5, 6, 7, 8 is able to control the 1st control contour 11 of the actuating element 9, 10, 11, 12,
[0050] 13 to be applied.
[0051] This is because the opening direction EÖ of the electric motor drive 4, 5, 6, 7, 8 in the front view according to Fig. 1 corresponds to a counterclockwise movement in the rear view according to Fig. 2 and to the fact that after completing a corresponding pivoting path, the 1st counter contour 6 of the electric motor drive 4, 5, 6, 7, 8 reaches the 1st control contour 11 of the actuating element 9, 10, 11, 12, 13 and in this way moves the actuating lever 10, which is rigidly coupled to the 1st control contour 11, downwards against the force of the spring 13, so that the coupling element or the coupling pin 9 is transferred from its previously assumed “disengaged” position to the “engaged” position.
[0052] As a result, the safety unit 14, 15, 16 is at least temporarily transferred to its "unlocked" position, which is the opposite of the initial "locked" position. The subsequent and optional reversing of the electric motor drive 4, 5, 6, 7, 8 results in the safety unit 14, 15, 16 being transferred back to its initial "locked" position in the exemplary embodiment, because the reversing movement of the output pulley 4 results in a clockwise movement in the illustration according to the
[0053] Fig. 2 corresponds, so that the 1st counter contour 6 leaves the 1st control contour 11 and the spring 13 can transfer the coupling pin 9 back into its “disengaged” position.
