Description

Technical Field

[0001] The invention relates to a motor vehicle lock, in particular a motor vehicle door lock, having a locking mechanism and an electric drive, the locking mechanism essentially comprising a bolt / ratchet and a pawl / pawl, the electric drive not only acting on a release lever to electrically open the locking mechanism but also, in most cases, simultaneously loading a safety unit and interacting with an adjusting element for this purpose. Background Art

[0002] 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, but in principle other applications in or on a motor vehicle are also conceivable, such as application on and use in connection with a motor vehicle hatch, etc. With regard to such motor vehicle locks, in particular motor vehicle door locks, it is generally desirable to equip the frequently used electric drive with as many functions as possible, since such electric drives are typically designed to be cost-intensive. For this reason, attempts are made to implement as many functions as possible in such motor vehicle door locks while using a (single) electric drive.

[0003] In practice, the prior art, for example according to WO 2019 / 076399 A1, provides that the electric drive is equipped with a drive element which acts indirectly or directly on the locking mechanism. Furthermore, the drive element interacts position-dependently with at least one further element, wherein the further element is a coupling element of an additionally implemented mechanical actuation lever system. This already provides a compact, cost-effective and functionally suitable structure.

[0004] In the prior art of this type according to WO 2021 / 115537 A1, the following measures are taken, that is, the locking mechanism can be locked, unlocked or opened simultaneously by means of a drive unit or an electric drive. Manual opening of the locking mechanism is usually prohibited by means of a locking unit.

[0005] In this way, a motor vehicle lock, in particular a motor vehicle door lock, is provided as a whole, which is constructed in a simplified manner and has a smaller number of components than previous motor vehicle locks. In addition, a cost-effective and structurally simple solution should be provided.

[0006] In principle, this prior art has proven that it involves using multiple functions with the aid of an electric drive and that in this respect the electric opening of the locking mechanism is ensured, in most cases the safety unit is simultaneously transferred to its "safe" position, or that the locking of the operating lever can be simultaneously achieved according to this type of teaching. However, other improvements can also be achieved and are considered with respect to this type of prior art. For the design implementation, the known teaching interacts with the adjusting element and the control lever. Here, the adjusting element is provided as a component of the electric drive. The operating lever can be engaged with the release lever by means of the control lever. Summary of the invention

[0007] The object of the present invention is to develop such a motor vehicle lock, in particular a motor vehicle door lock, in such a way that the design complexity is further reduced and a more compact design is achieved compared to previous embodiments.

[0008] In order to solve this technical problem, this type of motor vehicle lock, in particular a motor vehicle door lock, is characterized within the scope of the present invention in that when the locking mechanism is electrically opened along the opening direction of the electric drive, the adjusting element at least temporarily transfers the safety unit to its adjustment position opposite / opposite to the initial position, and preferably transfers the safety unit to its initial position again during the reversal / reverse movement.

[0009] In this way, when the locking mechanism is opened electrically in the opening direction of the electric drive, the safety unit is at least temporarily transferred to the adjustment position. Here, the adjustment position deviates from the initial position. If the initial position is, for example, the "safety" position of the safety unit, the adjustment position corresponds to the opposite "released" position. The opposite can also be handled. In this case, the initial position can belong to the "released" position, while the opposite adjustment position represents the "safety" position in this case.

[0010] The general advantage of this procedure is that, for example, in the case of a safety unit designed as an immobilizer or locking unit and in the typically assumed "immobilizer locked" or "locked" initial position, the electric opening of the locking mechanism is associated with the fact that the safety unit at least temporarily assumes the "immobilizer unlocked" or "unlocked" position, so that the door can be easily opened. As soon as the electric drive is reversed from this point on, the relevant safety unit is preferably transferred back into its initial position or transferred into the initial position by means of the electric drive, specifically and in the example described, into the "immobilizer locked" or "locked" position.

[0011] Similar advantages are achieved in the case where the safety unit has first already assumed its "armed" or "immobilizer unlocked" or "unlocked" position as the initial position and the electric drive is acted upon in its opening direction. In this case, the adjusting element acted upon by the electric drive ensures that the safety unit is at least temporarily transferred to its "armed" functional position or, in the specific example, to its "immobilizer locked" or "locked" functional position. This results in the safety unit being in the "armed" state during the electric opening process, so that no functional interference or collision with the electric drive occurs in the motor vehicle lock when, for example, the manual handle is acted upon by the user at the same time.

[0012] As soon as the safety unit assumes its at least temporarily assumed "safety" functional position, the actuating lever system which may be additionally provided for manually opening the locking mechanism is disconnected. As a result, the actual electric opening process can be carried out without interruption in both cases, and no functional interference or collision with the rod of the mechanical actuating lever system occurs during additional manual application. The additional and preferably implemented process, namely that the safety unit is transferred back to its initial position when the electric drive is reversed, also ensures that a "memory effect" is achieved.

[0013] Here, the motor vehicle lock returns to the state that had been occupied before starting and starting electric opening. As long as the safety unit performs the temporary state change from the initial position to the adjustment position when the locking mechanism is opened electrically, this state change is usually insignificant because the associated motor vehicle door is already opened.

[0014] In addition, there is advantageously the possibility that the electric drive selectively transfers the safety unit into an initial position or an adjustment position in its anti-opening direction. That is, the safety unit can be transferred to its desired position independently of the electric drive in the anti-opening direction relative to the opening direction assumed by the electric drive in connection with the electric opening locking mechanism. This position can be both an "armed" position and a "safe" position. This depends on which initial position was previously respectively assumed and which adjustment position the safety unit is then transferred to.

[0015] In this way, the safety unit can be easily operated as an electric child lock unit. That is to say, for example, after an electric opening process of the associated motor vehicle door, there is the possibility of selectively transferring the relevant safety unit or child lock unit to the desired "armed" position or "child lock unlocked" position and "safe" position or "child lock locked" position by the electric drive. Here, after such an electric opening process, after the electric drive is reversed and accordingly when the motor vehicle door is closed, the electric drive can be operated in the opposite opening direction.

[0016] In this anti-opening direction, the safety unit can be advantageously and selectively transferred into an initial position or into an adjusted position. In this case, a transfer into an initial position is usually not necessary, since the safety unit is preferably already and again adjusted into its initial position during the reversal. However, if this advantageous variant is not used, the following possibility is usually achieved in the anti-opening direction by means of an electric drive, i.e., the safety unit approaches two basic functional positions by means of the electric drive. In other words, the electric drive can load the safety unit in the anti-opening direction in a "safe" manner, independently of the electric opening process, and can also load the safety unit in a "released" manner.

[0017] This reduces the overall design costs, because the electric drive is used as the only drive for electrically opening the locking mechanism on the one hand and for controlling and loading the safety unit on the other hand. As described, any functional interference can be avoided here. This is a major advantage of the present invention.

[0018] According to another advantageous embodiment, the adjusting element is usually equipped with a first control shaped part and a second control shaped part. In this case, the following embodiment is further adopted, that is, the first control shaped part at least temporarily loads the safety unit in the opening direction of the electric drive. The second control shaped part ensures that the safety unit is loaded in the opposite opening direction, preferably permanently. In other words, the safety unit is usually loaded permanently by means of the second control shaped part, that is, in the opposite opening direction of the electric drive.

[0019] In most cases, the following measures are further taken, namely, the two control profiles are connected to a common shaft of the adjusting element. In this case, the two control profiles can be connected together to the adjusting rod. In this regard, it has also been proven that a first control profile of the adjusting element is loaded by means of a first counterpart profile of the drive device, and a second control profile of the adjusting element is loaded by means of another second counterpart profile of the drive device. In this case, the two counterpart profiles of the drive device are usually arranged on the outer circumference of the output wheel as a component of the drive device. In contrast, an operating cam for loading the release lever is usually provided on the opposite side of the output wheel.

[0020] Furthermore, a design is further provided in which a coupling element is provided as a component of the adjusting element. It is advantageous if the coupling element is guided in a coupling recess of the securing unit. The coupling element can be a coupling bolt which, in its "engaged" state, ensures that two actuating levers as components of the actuating lever system are operatively connected to one another, so that the release lever is acted upon by the two actuating levers and the locking mechanism can be opened by means of the release lever. For this purpose, the release lever usually acts on the pawl and releases the pawl from its locking engagement with the locking tongue.

[0021] On the contrary, if the coupling element or the coupling bolt is located in its "disengagement" functional position, the two operating levers are not operatively connected to each other and the corresponding loading of the operating lever system is invalid. Logically, the locking mechanism cannot be opened by the release lever in this case.

[0022] A motor vehicle lock, in particular a motor vehicle door lock, is thus provided, which is characterized by a particularly compact and functionally suitable design. To ensure this, it is first and foremost important that the electric drive is the only drive. With the aid of this single electric drive, not only can the locking mechanism be opened electrically, but also a safety unit can be loaded. In this case, this safety unit can be designed as an anti-theft lock unit, a locking unit or a childproof lock unit. In principle, combinations are also conceivable.

[0023] In this respect, the safety unit is particularly preferably designed as a child lock unit or an electric child lock unit. Here, the safety unit or child lock unit in question can be selectively transferred to its two basic adjustment positions, namely the "released safety" position or "child lock unlocked" position and the "safety" position or "child lock locked" position, in the anti-opening direction by means of an electric drive. In principle, of course, the safety unit can also be a locking unit and an anti-theft lock unit.

[0024] All of this is achieved with a compact and yet functionally suitable design, since the temporary change of state of the safety unit during the electric opening of the locking mechanism, first from the initial position to the opposite adjustment position and then back to the initial position again during the reversal, is insignificant during the electric opening process, since the associated motor vehicle door is already open in this case. In fact, this procedure corresponds to a "ballpoint pen principle", i.e., the first loading by means of the electric drive transfers the safety unit from the initial position to the adjustment position, and then the reloading by means of the electric drive (during the reversal) transfers the safety unit back to the initial position. This is a major advantage of the invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The invention is described in detail below with reference to the accompanying drawings which show only one embodiment; in the drawings:

[0026] Figure 1 and Figure 2 Respectively in front view ( Figure 1 ) and rear view ( Figure 2 ) shows a motor vehicle lock according to the invention, in particular a motor vehicle door lock, each simplified into the elements that are important to the invention. DETAILED DESCRIPTION

[0027] The drawings show a motor vehicle lock which, according to this embodiment, is a motor vehicle door lock. Figure 1 The locking mechanism 1 and 2 are briefly shown in the figure, and the locking mechanism mainly includes a lock tongue 1 and a lock claw 2. The locking mechanism 1 and 2 are arranged according to Figure 1 In the figure of , it is shown in the locked state. Here, a release lever 3 can also be seen, which can be loaded by means of an electric drive 4, 5, 6, 7, 8.

[0028] For this purpose, the electric drive 4, 5, 6, 7, 8 has an output wheel 4 and an actuating cam 5 arranged on the output wheel 4, which can be adjusted according to the Figure 1 Here, the output wheel 4 is rotated by means of the motor 8 which is only schematically shown. Figure 2 A first counter-shaped portion 6 and a second counter-shaped portion 7 as components of the electric drive 4, 5, 6, 7, 8 are also provided on the back side as seen in FIG.

[0029] As already explained, the electric drive 4, 5, 6, 7, 8 can first act on the release lever 3 to electrically open the locking mechanism 1, 2. For this purpose, the electric drive 4, 5, 6, 7, 8 is Figure 1 The opening direction is shown schematically in The upper edge is loaded in the clockwise direction represented by the arrow. This causes the operating cam 5 connected to the output wheel 4 in the front view to move to the extent that the release lever 3 is moved along the clockwise direction by the operating cam 5. Figure 1 In this way, the release lever 3 can load the pawl 2 with the release arm 3a, which then disengages the locking engagement with the bolt 1 in the clockwise direction about its axis. The bolt 1 is thus swung in a spring-assisted manner along the locking axis. Figure 1 The motor vehicle door of the embodiment of the present invention is opened in the counterclockwise direction, which is also shown schematically in the figure, and the locking pin, which is not shown here, is released. The associated motor vehicle door can then be opened.

[0030] In addition to the described electric opening locking mechanism 1, 2, the electric drive device 4, 5, 6, 7, 8 is also configured and can in most cases simultaneously load the safety unit 14, 15, 16. For this purpose, the electric drive device 4, 5, 6, 7, 8 can interact with the adjustment element 9, 10, 11, 12, 13.

[0031] The adjusting elements 9, 10, 11, 12, 13 are arranged in the opening direction of the electric drive 4, 5, 6, 7, 8 as described above. When the locking mechanism 1 , 2 is opened electrically, the securing unit 14 , 15 , 16 is at least temporarily transferred into its adjustment position opposite to the initial position and when the electric drive 4 , 5 , 6 , 7 , 8 is reversed, the securing unit is preferably transferred back into its initial position.

[0032] For this purpose, the following design is first adopted in detail, that is, the adjusting elements 9, 10, 11, 12, 13 have a coupling element 9 as a component. The coupling element 9 is a coupling bolt 9, which is particularly movable on the actuating lever 14 as a component of the safety unit 14. Figure 2 In addition to the actuating lever 14 , a further actuating lever 15 is provided, which are coaxially mounted about a common axis 16 and together define the securing unit 14 , 15 , 16 .

[0033] If the coupling element or coupling bolt 9 is located at Figure 2 In the "disengaged" position shown in solid lines in FIG. 1 , the action of the actuating lever 15 in the counterclockwise direction shown schematically here about the common axis 16 results in that the actuating lever 15 cannot drive the actuating lever 14 because the coupling bolt 9 is "disengaged". Corresponding to this is the "safety" functional position of the safety units 14, 15, 16 formed in this way.

[0034] If, on the other hand, the coupling element or coupling bolt 9 occupies the coupling recess of the actuating lever 14, Figure 2 In the position ("engaged") indicated schematically by dash-dot lines in FIG. 1 , the actuating lever 15 is loaded in the counterclockwise direction as already described, resulting in the two actuating levers 14, 15 being mechanically coupled to one another via the coupling bolt 9 and thus pivoting together in the schematically indicated counterclockwise direction about the common axis 16. As a result, the two actuating levers 14, 15 can pivot the release lever 3, which is coaxially mounted about the axis 16, likewise in the counterclockwise direction, so that in this way the pawl 2 is disengaged from its locking engagement with the bolt 1, as already described at the outset. For this purpose, the two actuating levers 14, 15 and the release lever 3 are mounted about the common axis 16.

[0035] The previously described securing units 14, 15, 16 are acted upon as a whole by means of the adjusting elements 9, 10, 11, 12, 13. The coupling element or coupling bolt 9 is a component of the adjusting elements 9, 10, 11, 12, 13. Furthermore, the adjusting elements 9, 10, 11, 12, 13 are also provided with an adjusting rod 10 in this case, which has a first control profile 11 and a second control profile 12 at the end. Furthermore, a spring 13 is provided for acting on the adjusting rod 10, which, according to this embodiment, corresponds to Figure 2 The view in FIG. 1 ensures that the adjusting rod 10 is preloaded toward the “disengaged” position of the coupling element or coupling bolt 9. In practice, the coupling element or coupling bolt 9 is connected to one end of the adjusting rod 10, while the two control profiles 11, 12 are located at the other end and are arranged there.

[0036] The working principle is as follows. Figure 1 Starting from the locked position of the diagram in FIG, the electric drive devices 4, 5, 6, 7, 8 are moved in the opening direction The loading ensures that the release lever 3 disengages the pawl 2 from its locking engagement with the bolt 1 by actuating the cam 5. The adjusting elements 9, 10, 11, 12, 13 in most cases simultaneously ensure that the safety units 14, 15, 16 are loaded. Specifically and corresponding to Figure 2 The following process corresponds to the view in FIG. 1 : The first control profile 11 as a component of the adjusting elements 9 , 10 , 11 , 12 , 13 is approached or acted upon by the first counter-profile 6 on the output wheel 4 . Figure 1 Opening direction in the front view corresponds to a movement in the clockwise direction and accordingly Figure 2 The rear view corresponds to counterclockwise movement.

[0037] This results in the coupling bolt 9 being transferred from its previously occupied "disengaged" position, which was preloaded by means of the spring 13, into the "engaged" position. When the locking mechanism 1 , 2 is opened electrically, it is transferred from the illustrated “released” initial position of the safety units 14 , 15 , 16 or the “disengaged” initial position of the coupling bolt 9 to the opposite adjustment position and thus to the “safety” position and the “engaged” position of the coupling bolt 9 .

[0038] If the electric drive 4, 5, 6, 7, 8 is now reversed, the safety unit 14, 15, 16 returns to its initial position or is transferred to the "safe" initial position. This is because when the electric drive 4, 5, 6, 7, 8 is reversed, the coupling element or coupling bolt 9 - under the load of the spring 13 - once again assumes its "disengaged" position. The change of state described in this way, that the safety unit 14, 15, 16 first temporarily changes from the "safe" position to the "released" position and then returns to the "safe" initial position after the reversal, is overall insignificant, because the locking mechanism 1, 2 has already been opened by means of the electric drive 4, 5, 6, 7, 8, and the associated motor vehicle door is therefore open.

[0039] If, for example, the motor vehicle door is now in its closed state and the locking mechanisms 1, 2 are also in their Figure 1 , the electric drive 4, 5, 6, 7, 8 can selectively transfer the safety unit 14, 15, 16 to the initial position or the adjustment position in the reverse opening direction, that is, specifically to the "safety" position or the "released safety" position. Since the safety unit 14, 15, 16 has already reached its "safety" position after the electric drive 4, 5, 6, 7, 8 is reversed within the scope of this embodiment, it is not necessary to additionally approach this position in the reverse opening direction in most cases. More precisely, it can be Figure 2 Starting from the position in , the “released” adjustment position of the safety units 14 , 15 , 16 is approached.

[0040] Correspondingly, the second control shaped portion 12 as a component of the adjusting elements 9, 10, 11, 12, 13 is moved in the relevant counter-opening direction, i.e. in the Figure 2 The securing units 14, 15, 16 are preferably permanently acted on in the clockwise direction. This is ensured by the second counter-shaped part 7 of the electric drive 4, 5, 6, 7, 8, by means of which the second control shaped part 12 of the adjusting element 9, 10, 11, 12, 13 is acted on.

[0041] This process specifically corresponds to the output wheel 4 being loaded in the opposite opening direction of the electric drive device 4, 5, 6, 7, 8, so that according to Figure 2. This causes the second mating shaped part 7 of the electric drive 4, 5, 6, 7, 8 to load the second control shaped part 12 of the adjusting element 9, 10, 11, 12, 13. Since the second control shaped part 12 is designed as a double-arm lever that can be pivoted about an axis and is articulatedly connected to the adjusting rod 10, the clockwise movement of the second mating shaped part 7 of the drive 4, 5, 6, 7, 8 causes the adjusting rod 10 to move downwards against the force of the spring 13 via the second control shaped part 12, and thus the coupling bolt 9 is transferred from its previously "disengaged" position in the initial position and thus the "safety" position of the safety units 14, 15, 16 to the "engaged" position. Therefore, the safety units 14, 15, 16 also occupy their corresponding "disengaged" positions in this case. Figure 2 Position of the Armed feature in the dash-dot view.

[0042] Once the electric drive devices 4, 5, 6, 7, 8 are moved in their opening direction When loaded, the second mating molding 7 moves back and releases the second control molding 12, so that the adjusting rod 10 is loaded by the spring 13. Figure 2 , and the coupling bolt 9 or the coupling element 9 is accordingly "released". As a result, the safety units 14, 15, 16 are again transferred into their "safety" position. However, in this case, the first counter-shaped part 6 has not yet reached the first control shaped part 11 of the adjusting element 9, 10, 11, 12, 13. This can only occur if, in connection with the electric opening locking mechanism 1, 2, the output wheel 4 has already traveled such a long distance that the actuating cam 5 reaches the release lever 3. In this case, the first counter-shaped part 6 of the electric drive 4, 5, 6, 7, 8 can act on the first control shaped part 11 of the adjusting element 9, 10, 11, 12, 13.

[0043] Here, the opening direction of the electric drive devices 4, 5, 6, 7, 8 is In accordance with Figure 1 corresponds to counterclockwise motion in the front view and in accordance with Figure 2 In the rear view, after completing the corresponding swing stroke, the first matching molded part 6 of the electric drive device 4, 5, 6, 7, 8 reaches the first control molded part 11 of the adjusting element 9, 10, 11, 12, 13 and in this way causes the adjusting rod 10 rigidly connected to the first control molded part 11 to move downward against the force of the spring 13, so that the connecting element or the connecting bolt 9 is transferred from the "disconnected" position it previously occupied to the "connected" position.

[0044] As a result, the safety units 14, 15, 16 are then at least temporarily transferred to their "released" adjustment position opposite to the "safe" initial position. The subsequent and optional reversal of the electric drive 4, 5, 6, 7, 8 results in the safety units 14, 15, 16 being transferred again to their "safe" initial position within the scope of this embodiment, since the reversing movement of the driven wheel 4 corresponds to the reversing movement according to Figure 2 , so that the first counter-shaped part 6 moves away from the first control shaped part 11 and the spring 13 can transfer the coupling bolt 9 back into its “disengaged” position.
