Description

Technical Field

[0001] The invention relates to a motor vehicle lock, in particular a motor vehicle door lock, comprising: a locking mechanism mainly comprising a bolt / ratchet and a pawl / pawl; an operating lever system including an associated door handle; an electric drive; and a safety unit, wherein the electric drive acts not only on the locking mechanism for electric opening, but also on the safety unit and loads the safety unit at least briefly during the electric opening. Background Art

[0002] The motor vehicle lock is preferably a motor vehicle door lock, although the motor vehicle lock mentioned above does not necessarily have to be associated with a motor vehicle door or used on a motor vehicle door. In principle, other applications in or on a motor vehicle are also conceivable, for example in connection with a motor vehicle hatch or the like. With regard to such motor vehicle locks, in particular motor vehicle door locks, it is basically intended that the frequently used electric drive devices are equipped with as many functions as possible. This may be due to the fact that electric drives are typically designed to be cost-intensive.

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

[0004] In another prior art according to WO 2021 / 115537 A1, the following measures are taken, namely, the locking mechanism can be locked and 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. This provides a motor vehicle lock that is constructed in a simplified manner and has a small number of components. In addition, a cost-effective and structurally simple solution is achieved.

[0005] In the prior art of this type, the following measures are taken according to the unpublished patent application DE 10 2021 128 868, namely, the unlocked safety unit is locked at least temporarily by means of an adjusting element that interacts with the electric drive. This occurs in the opening direction of the electric drive. In the opposite opening direction of the drive, the safety unit is selectively transferred to the locked position or the unlocked position.

[0006] All the prior art previously considered has been proven in principle. Then, "at least briefly, during the electric or motor-driven opening, the 'locked' position, in particular of the safety unit, is assumed to ensure that the load on the door handle has no effect on the locking mechanism. As a result, no collisions or malfunctions can occur between the electric drive and the actuating lever system, and no irrelevant functional positions of the actuating lever mechanism or the actuating lever system can be observed.

[0007] However, problems may occur in the known methods when the electric drive is damaged or fails. In this case, the associated motor vehicle door or motor vehicle hatch cannot be opened or can only be opened with an additional device. The present invention will remedy this in general. Summary of the invention

[0008] 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 an emergency operation, in particular manual opening of an associated door or hatch, is also possible.

[0009] 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 the locking mechanism can be opened by a two-stroke operation of the door handle in addition to an electric drive, wherein the two-stroke operation is released or invalidated during the electric or motor-driven opening.

[0010] That is to say, according to the invention, the motor vehicle lock, in particular the motor vehicle door lock, can typically and usually be opened electrically or motor-driven. For this purpose, an electric drive is used, which acts indirectly or directly on a pawl as a component of the locking mechanism for this purpose. As a result, the pawl is disengaged from its locking engagement with the bolt. The bolt is usually opened in a spring-assisted manner and releases the previously caught locking pin. The associated motor vehicle door can be opened.

[0011] If the electric drive fails, this is because the electric drive is damaged, the associated battery voltage is too low or after an accident, the motor vehicle lock according to the present invention can now also be opened manually. When the electric drive fails, the above situation is realized by the double-stroke operation of the door handle. Here, this double-stroke operation is typically realized by so-called "bridging". That is to say, additional unlocking of the associated motor vehicle lock is usually not required. More precisely, the double-stroke operation is realized in such a way that the coupling part or the coupling element is locked in the first stroke of the door handle, so that in another second stroke of the door handle, the operating lever system that is also locked can be loaded in the following way by the locked coupling element, that is, the locking claw is disengaged from its locking engagement with the lock tongue again. The locking mechanism can thus be opened manually, that is, it is independent of the electric drive.

[0012] The two-stroke actuation ensures in this case that "for example, accidental and possibly unintentional loading of the door handle" does not directly lead to the door opening. Rather, the prerequisite for "manually opening the door" is that two deliberate actuations are carried out by the two-stroke actuation.

[0013] In order that loading of the door handle during electric or motor-driven opening, for example, does not lead to a collision between the operating lever system with the door handle at the end on the one hand and the electric drive or the locking mechanism loaded by it on the other hand, it is additionally provided according to the invention that the two-stroke operation is released during the electric opening. That is to say, the door handle can be loaded in principle during the electric opening process, i.e., the locking mechanism does not and cannot be opened here. Therefore, the two-stroke operation cannot be realized during the electric opening process. In addition, it helps that the safety unit is typically in its "locked" state during the electric or motor-driven opening. As a result, the operating lever system is additionally interrupted and the coupling element already mentioned above cannot be transferred to its state of locking the operating lever system.

[0014] In this way, any mechanical collision between the actuating lever system on the one hand and the electric drive and the locking mechanism acted upon by it on the other hand is avoided in principle from the outset. At the same time, perfect functionality is ensured, since the typically "locked" and only briefly "unlocked" safety unit ensures interruption of the actuating lever system during the electric opening process and in addition the two-stroke actuation is disabled, so that although the door handle can be acted upon, the two-stroke actuation cannot be used to lock the actuating lever system to open the locking mechanism. All this is achieved while taking into account a functionally reliable, simple and cost-effective design. This is a major advantage of the invention.

[0015] According to an advantageous design, the at least two-part coupling element is arranged between the electric drive and the door handle. In most cases, the following measures are taken, namely, the at least two-part coupling element consists of a first coupling rod of the coupling element and a second coupling rod of the coupling element. The first coupling rod of the coupling element is in most cases indirectly or directly connected to the door handle. In the case of indirect connection to the door handle, the first coupling rod and the relevant door handle can be connected to each other in an articulated manner, for example. However, in most cases, a rigid or flexible connecting member is provided between the first coupling rod and the door handle. The flexible connecting member is usually a Bowden cable. As a result, the relevant first coupling rod is indirectly connected to the door handle. In contrast, the other second coupling rod of the coupling element is connected to a transmission rod that interacts with the electric drive.

[0016] In order to connect two connecting rods, the present invention proposes two principle methods. In the scope of the first variant, the two connecting rods are connected to each other or interact with each other by a control profile moving along the guide rail. Here, the control profile can be arranged on the second connecting rod, which is connected to the transmission rod.

[0017] The present invention proposes within the scope of another second variant that the two coupling rods interact with each other through an additional third coupling rod. Here, the third coupling rod itself is usually connected to the second coupling rod in an articulated manner.

[0018] Since the second coupling rod of the coupling element is acted upon by means of a transmission rod, which itself interacts with the electric drive, the following design is also adopted, namely, the transmission rod is equipped with at least a first transfer contour and a second transfer contour. The first transfer contour is designed in this case so that the first transfer contour acts on the second coupling rod. In contrast, the second transfer contour of the transmission rod is acted upon by the adjusting element. The adjusting element itself interacts with the electric drive, as will be described in detail below with reference to the accompanying drawings.

[0019] Within the scope of the invention, the (two-part) coupling element arranged between the electric drive and the door handle is not only used as a safety unit or a component thereof, but also can simultaneously enable and disable the two-stroke operation of the door handle or activate and deactivate the two-stroke operation by means of the coupling element.

[0020] In this case, the electric drive is advantageously usually equipped with a return spring that acts on one side. This return spring ensures that the electric drive is moved back to its starting position by means of this return spring, especially when it is reversed after the motor-driven opening process. Finally, it has been proven to be particularly advantageous that the operating lever system is designed as an internal operating lever system and the door handle is designed as an internal door handle. In this way, the motor vehicle lock according to the present invention can usually be opened in an electric or motor-driven manner, that is to say not only from the inside but also from the outside. Here, mechanical redundancy is typically and advantageously achieved only by internal manipulation. It goes without saying that within the scope of the present invention, mechanical redundancy is alternatively also achieved by external manipulation. Mechanical redundancy can also be achieved by internal manipulation as well as external manipulation. However, in all cases, the prerequisite is the double-stroke manipulation of the relevant door handle as described above.

[0021] In this way, the following measures are generally taken, namely, "charging the door handle or the additionally provided outer door handle for electric opening" first and as usual corresponds to charging a switch or usually a sensor assigned to the door handle or the outer door handle. Sensor actuation corresponds to the electric drive being started and the pawl being disengaged from its locking engagement with the locking tongue during the electric opening process. In this process, the safety unit is charged at least briefly during the electric opening and usually returns to its starting position after the electric opening.

[0022] If the safety unit was in its "unlocked" functional state before the electric opening, the safety unit is transferred at least briefly to its "locked" position during the electric opening, which corresponds to the interrupted actuation lever system. As a result, any load on the door handle is unloaded during the electric opening. After the electric opening process is completed, the safety unit returns to the original "unlocked" functional position after briefly occupying the "locked" position.

[0023] After the electric opening, the electric drive is usually reversed. During the reversal, the possible locked state of the coupling or coupling element that was introduced in connection with the actuation of the door handle is cancelled. As a result, the double-stroke actuation of the door handle is released and the locking mechanism cannot be opened manually.

[0024] After the electric opening process is completed, the electric drive is reversed. The safety unit is moved back to the "unlocked" starting position described in the example. The coupling element is locked, so that in principle, after the electric opening process is completed, the locking mechanism can be opened by a two-stroke actuation of the door handle.

[0025] The return spring assigned to the electric drive ensures that the electric drive is reversed out of the starting position and back in the direction of the starting position. The electric drive is now in its starting position again. As long as the electric drive fails in this starting position, the locking mechanism can now be manually opened by the described two-stroke actuation of the door handle. This is achieved independently of the position of the safety unit, whether the position is "unlocked" or "locked". Because the safety unit jumps over in the two-stroke actuation as if by "bridging". This is a major advantage of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The invention is described in detail below with reference to the accompanying drawings which show only one embodiment; in the drawings:

[0027] Figures 1 to 8 A first variant of a motor vehicle lock is shown in different functional positions, and

[0028] Figures 9 to 12 A further second variant is shown, also in a different functional position. DETAILED DESCRIPTION

[0029] The figures show a motor vehicle lock having a locking mechanism 1, 2 comprising a locking tongue 1 and a locking pawl 2. The locking mechanism 1, 2 is only Figure 1 In addition, an actuating lever system 3, 4, 5, 6, 7 is provided, which is designed as an inner actuating lever system 3, 4, 5, 6, 7 according to this embodiment. In addition, a release lever 8 can be seen, which is used to release the pawl 2 in an electric or motor-driven manner.

[0030] The lever system 3, 4, 5, 6, 7 is composed according to this embodiment of the invention of a lever or inner lever 3 and a door handle 7 acting on the lever or inner lever 3, which is an inner door handle 7 according to this embodiment of the invention. In addition, the lever system 3, 4, 5, 6, 7 includes a first coupling rod 4 and a second coupling rod 5. Figures 1 to 8 In the scope of the variant, an additional third coupling rod 6 is also realized and arranged, which is arranged according to Figures 8 to 12 is not reflected in the implementation method.

[0031] Common to both variants is an electric drive 9, 10, 11, which according to the exemplary embodiment is equipped with an electric motor 9, by means of which a worm gear 10 can be rotated. In addition, an actuating contour 11 on the worm gear 10 can be seen, which serves within the scope of this exemplary embodiment to actuate the release lever 8 and overall ensures an electric or motor-driven opening of the locking mechanism 1, 2, as will be explained in more detail below.

[0032] In this case, other basic structures also include the insurance unit 5, 6, which is based on Figures 1 to 8 The embodiment in the embodiment is composed of a second connecting rod 5 and a third connecting rod 6. Figures 9 to 12 In the embodiment variant, the control contour 12 finally assumes the function of the third coupling rod 6, which can be moved along the fixed guide rail 13. In this case, the control contour 12 on the second coupling rod 5 and the fixed guide rail 13 therefore assume the function of an alternative to the safety unit 5, 6 or 12, 13.

[0033] The following design is generally adopted here, namely that the electric drive device 9, 10, 11 not only acts on the locking mechanism 1, 2 for electric opening, but also acts on the safety unit 5, 6; 12, 13 and loads the relevant safety unit 5, 6; 12, 13 at least briefly during the electric or motor-driven opening.

[0034] It is now particularly important according to the invention that the locking mechanism 1, 2 can be opened by a two-stroke actuation of the door handle 7 in addition to the electric drive 9, 10, 11. This two-stroke actuation is released or ineffective during the electric opening. In fact, in the case of a two-stroke actuation of the door handle 7, the overall situation will be that the corresponding Figure 1 Starting from the initial position shown in FIG. 1 , the actuating lever or the inner actuating lever 3 here is pivoted about its axis in the counterclockwise direction when the door handle 7 is loaded, and thereby the first coupling rod 4 is in Figure 1 Move downward on the right side of the

[0035] For this purpose, the first coupling rod 4 of the coupling elements 4, 5, 6 is indirectly coupled to the door handle 7 according to this embodiment. Here, the indirect connection is implemented according to this embodiment via a Bowden cable, by means of which the door handle 7 acts on the first coupling rod 4. In principle, however, the door handle 7 can also be directly connected to the first coupling rod 4, but this is not shown.

[0036] If the fuse units 5 and 6 are not in Figure 1 In the "locked" or "child lock unlocked" state shown in FIG. 1 , since the safety units 5 and 6 are child lock units according to this embodiment, the locking mechanism 1 and 2 can now be opened in the second stroke of the door handle or the inner door handle 7. However, the prerequisite is that Figure 1 The safety units 5, 6 in the "locked" or "child lock open" position in the embodiment of the present invention occupy their "unlocked" or "child lock closed" position. Figure 8 Functional status.

[0037] Because in the "unlocked" position of the safety units 5, 6, the third coupling rod 6 is Figures 1 to 8 In the transition process of the door handle 7, the first coupling rod 4 is swung in the clockwise direction about its axis, so that in the first stroke of the door handle 7, the first coupling rod 4 can now engage with the locking pawl 2 with its release contour 4a. Figure 1 In the middle view of FIG. 4 , the pawl 2 is now swung in the clockwise direction by the release contour 4 a and thereby releases the locking tongue 1 . This can be done in a similar manner in the example of FIG. 4 . Figure 1 to Figure 2 , however, the manual opening process of the locking mechanism 1 , 2 is not shown here, but rather an electric opening process is shown in contrast.

[0038] The working principle is as follows. As described, the motor vehicle lock according to the present invention Figure 1 The same applies to the electric drive 9, 10, 11 or the worm gear 10. In principle, a two-stroke actuation is added or made possible. The safety units 5, 6 are in their "locked" functional position, because the third coupling rod 6 ensures that, when the door handle 7 is loaded, the release contour 4a passes by the pawl 2 and cannot be loaded.

[0039] Now in from Figure 1 to Figure 2 The opening process driven by an electric or motor can be seen in the transition process. This opening process corresponds to the loading of the door outer handle, which is not explicitly shown in the exemplary embodiment, with a sensor or switch, which in turn is queried by means of a control unit, which is not shown. The sensor actuation causes the control unit to load the motor 9, so that the motor is turned from Figure 1 to Figure 2In the transition process of the worm wheel 10 in the middle view, the worm wheel 10 is loaded in the counterclockwise direction. As a result, the actuating contour 11 moves against the release lever 8 on the front side of the worm wheel 10 and ensures that the pawl 2 is released from the release lever 8 as a whole. Figure 1 to Figure 2 The clockwise movement of the pawl 2 now corresponds to the pawl 2 being in the transition process of the locking mechanism 1, 2. Figure 1 1 . The locking bolt 1 is thus opened in a spring-assisted manner by a swinging movement about its axis in the clockwise direction and releases the previously caught locking pin. The associated door can be opened.

[0040] If the door handle 7 is loaded during the described electric opening process, such as Figure 3 As shown, this situation leads to the first coupling rod 4 moving downward. At the same time, the safety units 5, 6 are moved from the corresponding Figure 1 The "locked" position of the worm gear 10 has already occupied its "unlocked" functional position at least briefly. This can be attributed to the fact that, with the counterclockwise rotation of the worm gear 10 for electric opening, at the same time Figure 1 via Figures 2 to 3 During the transition process, the transmission rod 14 performs a swinging motion in the counterclockwise direction. For this purpose, the transmission rod 14 is equipped with a first transmission profile 14a and a second transmission profile 14b. The first transmission profile 14a loads the second coupling rod 5.

[0041] In fact, the counterclockwise movement of the transmission rod 14 is related to the electric opening process of the locking mechanism 1, 2. Figure 1 via Figures 2 to 3 In the transition process, the second coupling rod 5 moves "upwards", so that the third coupling rod 6, which is connected to the second coupling rod 5 in an articulated manner, swings around its axis in the clockwise direction in this way. As a result, the first coupling rod 4 (which is connected to the door handle 7 on the one hand and to the operating lever 3 or the inner operating lever 3 in an articulated manner according to this embodiment) can swing or move in the direction of the pawl 2 with its release contour 4a. However, since the guidance of the first coupling rod 4 by the third coupling rod 6 is cancelled, the double-stroke operation is generally cancelled. In other words, the first coupling rod 4 cannot interact with the pawl 2 with its release contour 4a and disengage the pawl from its engagement with the lock tongue 1.

[0042] Now if we go further from Figure 3 Transition to Figure 4 , the worm gear 10 reverses during this transition process. Figure 3 In the process, the pawl 2 is electrically disengaged from its engagement with the bolt 1, and the desired electrical opening occurs. After this, the electric drive devices 9, 10, 11 are reversed. Figure 3 to Figure 4In the transition process, the worm wheel 10 is correspondingly pivoted in the clockwise direction. At the same time, the actuating contour 11 is thus moved away from the release lever 8. The safety units 5, 6 are in their short "unlocked" or "child lock closed" position, such as substantially also completely in the Figure 8 As shown in , i.e. briefly. Since the double-stroke actuation is simultaneously released during the electric opening process, "manual opening of the locking mechanism 1, 2 by actuating the door handle 7" cannot act on the locking mechanism 1, 2 during the electric or motor-driven opening process. The locking mechanism therefore remains unaffected.

[0043] In from Figures 4 to 5 And further to Figure 6 It can be seen that the worm gear 10 has reversed to the corresponding Figure 1 As a result, the return spring 15, which is assigned to the worm gear 10 and is only briefly outlined here, is loaded. Figure 6 Afterwards, ensure that the worm wheel 10 is moved back as a whole to its corresponding Figure 1 The starting position of the view in . Figures 5 and 6 During the transition process, the safety units 5, 6 reoccupy the "locked" or "child lock open" position they originally occupied. Correspondingly, the third connecting rod 6 can interact with the first connecting rod 4, such as according to Figure 7 As a result, the first coupling rod 4 cannot move with its release contour 4a in the direction of the pawl 2 and thus cannot interact with the pawl 2 or disengage the pawl from its locking tongue 1. This can only be achieved by "bridging" over the safety unit 5, 6 or the third coupling rod 6.

[0044] As described, the transmission rod 14 is equipped with at least a first transmission contour 14a and a second transmission contour 14b. The first transmission contour 14a acts on the second coupling rod 5, while the second transmission contour 14b is acted on by the adjustment element 16. For this purpose, the adjustment element 16 is designed as a multi-arm type and is acted on by another contour not explicitly shown on the back side of the worm wheel 10 of the electric drive 9, 10, 11.

[0045] exist Figures 9 to 12 1 shows a modified embodiment. Here again, the transmission rod 14 and the adjusting element 16 acting on the transmission rod 14 can be seen. The transmission rod 14 acts on the second coupling rod 5 with the first transmission contour 14a. The second coupling rod 5 is equipped with a control contour 12, which can interact with the fixed guide rail 13 or can move along the guide rail 13.

[0046] exist Fig. 91 shows the safety unit 12, 13 formed in this way in the "locked" state. In addition, a double-stroke actuation is added in this case. Fig.10 The "locked" state of the safety units 12, 13 is shown again, and this time the double stroke operation is released. In both cases, the safety units 12, 13 ensure that the pawl 2 generally cannot be disengaged from its locking engagement with the bolt 1 when the operating lever 3 is loaded by the door handle 7.

[0047] If, on the other hand, the safety units 12, 13 are released or in their corresponding Fig.11 and Fig.12 In the "unlocked" or "child lock closed" state in the figure, the first coupling rod 4 can act on the pawl 2 via the operating rod 3 when the door handle 7 is loaded and the pawl is disengaged from its locking engagement with the bolt 1. In this case, the second coupling rod 5 abuts laterally against the first coupling rod 4. Therefore, in the first stroke of the door handle 7 (after the electric opening process), the first coupling rod 4 can be connected as a whole relative to the pawl 2, so that in the second stroke of the door handle 7, the pawl 2 finally disengages from its engagement with the bolt 1, and the locking mechanism 1, 2 is thus manually opened.
