Description

[0001] The present invention relates to a motor vehicle lock assembly for a closing element of a motor vehicle according to claim 1, a functional component for a motor vehicle according to claim 16, and a motor vehicle having a motor vehicle lock assembly or a functional component according to claim 17.

[0002] The term "closing element" should be interpreted broadly in this document. It includes, for example, tailgates, tailgates, hoods, side doors, cargo covers, windows, and liftgates of motor vehicles. The application of side doors in motor vehicles will be highlighted below. Closing elements may be equipped with a motor vehicle lock assembly, which is used to hold the closing element in the closed position and secure it against opening. Motor vehicle locks are designed to achieve increasingly convenient functions, particularly push-in and / or pull-out, with the lowest possible cost and minimal structural space requirements. Typically, motor vehicle locks have a latch with a bolt and at least one pawl.

[0003] When pushed in, the closing element moves to the gap position. The gap position is a position outside the open position of the vehicle lock. The open position is the position reached when the vehicle lock is open, i.e., when the pawl is disengaged. Due to the door sealing pressure and the spring bias of the latch (if needed), the closing element is slightly pushed in by the disengagement of the pawl, and the vehicle lock reaches the open position. However, especially in the case of modern handle-less side doors, the user should be able to open the side door by engaging the gap between the vehicle body and the side door. The gap in the open position is insufficient for comfortable engagement. Therefore, a push-in assembly is provided that further pushes in the side door, or more generally, pushes in the closing element. To push the closing element into the gap position, the push-in assembly has a push-in element and a motor with a motor shaft for adjusting the push-in element.

[0004] During the pull-out process, the latch is typically pulled from the pre-closed position to the main closed position by the motor, i.e., moved in its closing direction. Therefore, the user does not need to fully close the sealing element, but can bring it to the pre-closed position with minimal effort. Pull-out can also be advantageous when combined with an electric sealing element, because the sealing element's actuator does not need to exert force against the door seal pressure to bring the sealing element to the main closed position. Sealing element actuators are typically not designed for this combination of short distance and high torque.

[0005] The prior art upon which this invention is based (EP 1 536 090 A2) relates to a vehicle lock assembly as described in the preamble of claim 1. This vehicle lock assembly has a vehicle lock with a latch having a bolt and a pawl. Furthermore, the vehicle lock assembly has a drive assembly with a motor, wherein the drive assembly has a first flexible traction device. The motor can act on the first flexible traction device to trigger a first function of the vehicle lock assembly. The vehicle lock assembly is configured to trigger the first function using a first maximum traction force from the first flexible traction device. If in doubt, this is the maximum power of the motor, if it is not limited in some way. A drive with a flexible traction device has proven effective in implementing a single function in a vehicle lock. The more functions a vehicle lock has, the higher its cost and the larger the space required for the vehicle lock assembly.

[0006] In this context, implementing multiple functions of a vehicle lock in a cost-effective manner while taking into account structural space requirements is a challenge.

[0007] The present invention is based on the problem of designing and improving known motor vehicle lock components in such a way that further optimizations are made to address the aforementioned challenges.

[0008] This objective is achieved by the features of the feature portion of claim 1.

[0009] The basic consideration is to provide a second flexible traction device, driven by the same motor, to achieve a second function. However, it is generally expected that one of the two functions, here the second, will require less power than the other. This can be achieved by reducing the motor's power, for example, through PWM. Therefore, the two functions produce different maximum traction forces that can be applied to the flexible traction device. For example, 1000 N could be used for pushing in in the event of a collision, while a maximum of 400 N could be used for pulling out, also to prevent jamming.

[0010] The advantage of flexible traction devices is their ability to adapt flexibly to existing structural spaces through deflection and guidance, resulting in high flexibility. However, this deflection and guidance leads to frictional losses. According to the knowledge presented in the invention, flexible traction devices are now classified in such a way that those that must transmit less force have higher frictional losses, or at least deflect more frequently. Another advantage of making flexible traction devices that bear greater loads deflect less is that the deflection element must be designed to withstand maximum force, thus allowing for more advantageous design of the deflection element for a second flexible traction device. Therefore, the proposed teachings are advantageous even if friction is negligible.

[0011] Specifically, a drive assembly is proposed to have a second flexible traction device, and a motor can act on the second flexible traction device to trigger a second function of a vehicle lock assembly. The vehicle lock assembly is configured to trigger the second function using a second maximum traction force of the second flexible traction device, the second maximum traction force being less than a first maximum traction force, the second flexible traction device deflecting at least once, and the second flexible traction device deflecting more frequently and / or deflecting over a larger angle range than the first flexible traction device, and / or, given the same traction force, the friction loss of the second flexible traction device being higher than that of the first flexible traction device.

[0012] It should be noted that the maximum traction force during normal vehicle operation, including in the event of a collision, has been considered. Whether, theoretically, the motor can also exert its maximum force on the second flexible traction device through testing functions is irrelevant.

[0013] Claim 2 relates to a preferred design for the deflection and its variation in a flexible traction device.

[0014] Preferably, claim 3 provides a deflection element on which the flexible traction device deflects.

[0015] Claim 4 relates to preferred designs with different traction forces.

[0016] Claims 5 and 6 relate to preferred functions where the maximum force can be different, and therefore the teachings presented can be well applied to these functions.

[0017] Similar to deflection, torsion can also be provided, which can correspondingly occur more frequently in the second flexible traction device (claim 7).

[0018] Claim 8 relates to a preferred difference in friction loss.

[0019] According to claim 9, the first and second functions can be assigned different motor directions, thereby allowing them to be separated in a simple manner.

[0020] In the design according to claim 10, pushing in is associated with the first flexible traction device. In the design according to claim 11, pulling out of the pawl is associated with the first flexible traction device. Therefore, preferably, pushing in and pulling out are performed synchronously with each other via a common flexible traction device. In the design according to claim 12, pulling out is associated with the second flexible traction device. Pulling out is independent of pushing in and pulling out in time / function, and is therefore preferably associated with another motor direction.

[0021] Flexible traction devices, particularly two, can be wound onto a winding shaft, particularly onto the same winding shaft coaxial with the motor shaft, and unwound from the winding shaft. This further results in a compact arrangement (claim 13).

[0022] Claim 14 relates to a preferred design of the flexible traction device, wherein, in each case, the flexible traction device can be a belt. Furthermore, the sheathless design, particularly separate from the Bolton cable, increases flexibility and deflectability. Moreover, the sheath already provides partial protection against frictional losses, especially those caused by deflection, making the advantages according to the invention particularly apparent in the case of the sheathless flexible traction device. A belt can be more stable than a rope, while also being less expensive. Therefore, during deflection, more surface area typically rests on the deflecting element, resulting in potentially greater friction.

[0023] Since the motor is preferably designed to push into the enclosed element and perform the second function even after a collision, the latter can preferably be reduced (claim 15).

[0024] According to another teaching of independently related claim 16, a functional component for a motor vehicle is provided, wherein the functional component includes a drive component having a motor, wherein the drive component has a first flexible traction device, wherein the motor can act on the first flexible traction device to trigger a first function of the motor vehicle, particularly a first function of the functional component, wherein the functional component is configured to trigger the first function using a first maximum traction force of the first flexible traction device. Importantly, the drive component has a second flexible traction device, and the motor can act on the second flexible traction device to trigger a second function of the motor vehicle, particularly a second function of the functional component, wherein the functional component is configured to trigger the second function using a second maximum traction force of the second flexible traction device, wherein the second flexible traction device deflects at least once, and the second flexible traction device deflects more frequently and / or over a larger angle range than the first flexible traction device; preferably, the second maximum traction force is less than the first maximum traction force. The functional component may be a motor vehicle lock assembly. In all embodiments relating to a motor vehicle lock assembly, the term "motor vehicle lock assembly" may be replaced by "functional component," and a motor vehicle lock or an unwanted component of a motor vehicle lock may be considered optional. Preferably, the functional component is a functional unit whose parts form an assembly, and preferably cooperates with a motor vehicle lock, particularly an external drive unit, which includes one or more parts of a drive assembly and may include a control unit and / or one or more parts of a push-in assembly, thereby forming an assembly. Therefore, in particular, an external push-in unit can be provided as a functional component, wherein a first function is implemented in the push-in unit, and a second function is triggered, for example, via a Bolton cable connected to a second flexible traction device in the lock. It is recognized here that the fact that the flexible traction device deflects at different frequencies has led to increased flexibility in the arrangement of the flexible traction device.

[0025] All implementation schemes for the proposed motor vehicle lock components can be referenced.

[0026] According to another teaching of claim 17, which is also of independent significance, protection is claimed for motor vehicles having a motor vehicle locking assembly or a functional component according to the invention.

[0027] All implementation schemes of the proposed motor vehicle lock components and the proposed functional components can be referenced.

[0028] The invention will be explained in more detail below with reference to the accompanying drawings, which illustrate embodiments only. In the drawings:

[0029] Figure 1 The vehicle shown is a) having a vehicle lock in both b) the open position and c) the main closed position;

[0030] Figure 2 The vehicle lock is shown in the zero position;

[0031] Figure 3 The image shows a motor vehicle lock after the pawl has been disengaged;

[0032] Figure 4 The image shows a motor vehicle lock after the closure element has been inserted;

[0033] Figure 5 The image shows a vehicle lock after the latch has been pulled out; and

[0034] Figure 6 A variation of a motor vehicle lock is shown, in which two flexible traction devices act on the push-in element.

[0035] The vehicle locking assembly 1 according to the invention is provided with a closing element 3 adjustablely coupled to the vehicle body 2 of a motor vehicle. In this case, the closing element 3 is preferably a side door of the motor vehicle 4. However, the vehicle locking assembly 1 according to the invention can also be applied to all other conceivable closing elements 3 of the motor vehicle 4. These particularly include rear doors, tailgates, rear covers, or engine hoods. In this case, preferably, the closing element 3 designed as a side door can pivot about a substantially vertically oriented pivot axis. However, the closing element 3 can also be designed as a sliding door.

[0036] The embodiment shown in the figure, and preferred in this respect, relates to a motor vehicle lock assembly 1 for a closing element 3 of a motor vehicle 4.

[0037] The vehicle lock assembly 1 includes a vehicle lock 5, which is arranged on the enclosure element 3 in the assembled state. Optionally, the vehicle lock 5 may also be arranged on the vehicle body 2 of a motor vehicle. The vehicle lock 5 is equipped with a latch 6 having a bolt 7 and a pawl 8.

[0038] Through Figure 1 Adjusting the locking bolt 7 clockwise from the closing direction allows it to... Figure 1 b) The open position shown in the diagram is moved to at least one closed position. Figure 1 c) In this case, it is the main closed position and the pre-closed position. In the closed position, the latch 7 engages with the closing part 9, etc., to transmit the door holding force. The door holding force acts on the closing element 3 in the closing direction to counteract the opening of the closing element 3.

[0039] Conversely, the locking tongue 7 can be used in Figure 1 The adjustment moves the object from the closed position to the open position by rotating it counterclockwise. Figure 1 (b) In the open position, the latch 7 releases the closing portion 9 in the opening direction of the closing element 3.

[0040] As shown in the diagram, the pawl 8 is equipped with a locking tongue 7, and the pawl 8 can be moved to the locked position, in which the locking tongue 7 is locked in the closed position. Figure 1 c) is in the main closed position to prevent the latch 7 from pivoting in the opening direction. Furthermore, the pawl 8 can preferably be pulled out to the release position by a motor in this case, in which the latch 7 is released in its opening direction, allowing the latch 7 to pivot to its open position. Figure 1 In this context, moving pawl 8 to the release position is associated with a counter-clockwise pivoting of pawl 8. The release position of pawl 8 is as follows: Figure 1 As shown in b).

[0041] When the pawl 8 is spring-biased onto the latch 7, the latch 7, also spring-biased, is pushed into its open position. For clarity, the spring assembly required for this purpose is not shown here. The pawl 8 and / or latch 7 may have a plastic housing.

[0042] Furthermore, the vehicle lock assembly 1, preferably the vehicle lock 5, has a drive assembly 10 with a motor 11. A transmission device 12 can be connected downstream of the motor 11, and it can have at least one gear, and is preferably a planetary transmission device.

[0043] The drive assembly 10 has a first flexible traction device 13. The motor 11 can act on the first flexible traction device 13 to trigger a first function of the vehicle lock assembly 1. For example, the first function here is "pushing in the closure element". The vehicle lock assembly 1 is configured to trigger the first function using a first maximum traction force of the first flexible traction device 13. The maximum traction force is used here, and preferably not every time the first function is triggered, but only in certain situations, such as after a collision.

[0044] Importantly, the drive assembly 10 has a second flexible traction device 14. The motor 11 can act on the second flexible traction device 14 to trigger a second function of the vehicle lock assembly 1. This second function is, for example, "pulling out the latch." The vehicle lock assembly 1 is configured to trigger the second function using a second maximum traction force from the second flexible traction device 14. It is noteworthy that the second maximum traction force is less than the first maximum traction force. Therefore, in normal operation, pulling out will never be triggered by the traction force requiring the maximum power of the motor 11. The motor 11 is preferably adjusted down to keep the second maximum traction force below the first maximum traction force.

[0045] In order to adapt the flexible traction devices 11 and 12 to the structural space requirements and provide the flexible motor vehicle lock assembly 1, a second flexible traction device 14 is provided to deflect at least once, and the second flexible traction device 14 deflects more frequently and / or has a larger deflection angle range than the first flexible traction device 13.

[0046] As an alternative to or supplement to deflection, the friction loss of the second flexible traction device 14 is higher than that of the first flexible traction device 13 for the same traction force. This is preferably due to more frequent deflection.

[0047] Here, the first and second flexible traction devices 14 are preferably connected downstream of the transmission device 12.

[0048] Typically, preferably, the first flexible traction device 13 and / or the second flexible traction device 14 have a longitudinal direction along which the motion transmitted by the corresponding flexible traction devices 11, 12 is transmitted, and the corresponding flexible traction devices 11, 12 are flexible transversely to the longitudinal direction, preferably flexible, and / or the corresponding flexible traction devices 11, 12 are longitudinally stable in the longitudinal direction during motion transmission. Another advantage of the flexible traction devices 11, 12 is that they can be interchanged with pulleys. Therefore, the first flexible traction device 13 and / or the second flexible traction device 14 are preferably part of a pulley.

[0049] Generally, the term "flexible" in relation to traction devices means that they are flexible when orthogonal to the traction direction. In the traction direction, the corresponding flexible traction devices 11, 12 are preferably stable, such that the traction force generated does not cause a change in the length of the flexible traction devices 11, 12.

[0050] Here, and preferably, the first flexible traction device 13 deflects at least once and / or at least 90°, and / or the first flexible traction device 13 deflects at most twice, preferably at most once, and / or at most 270°, preferably at most 180°, and more preferably at most 120°.

[0051] The second flexible traction device 14 deflects here, preferably at least twice, preferably at least three times, and / or at least 120°, preferably at least 180°, and more preferably at least 200°. As can be seen from the figure, in the illustrated embodiment, the first flexible traction device 13 deflects precisely once and relatively precisely by 90°. The second flexible traction device 14 deflects three times: first by 90°, then by another 90°, and then by almost 45°. The second flexible traction device 14 deflects a total of approximately 225°. Therefore, the different directions of deflection are ignored when summing.

[0052] Furthermore, and preferably, the second flexible traction device 14 is provided here to deflect at at least two, preferably at least three deflecting elements 15, which are separated from each other by non-deflecting extensions of the second flexible traction device 14. The deflecting elements 15 can be rollers, pins, studs, etc. In this case, preferably, the deflecting elements 15 are separated from each other. The portions of the deflecting elements 15 that are not deflected are shown here as unguided, but the second flexible traction device 14 can also be guided in these portions. The first flexible traction device 13 here and preferably deflects at at most one deflecting element 15.

[0053] Preferably, the first maximum traction force is at least 500 N, more preferably at least 700 N, more preferably at least 900 N, and even more preferably at least 1000 N, and / or, the second maximum traction force is at most 700 N, preferably at most 500 N, and more preferably at most 400 N. Conversely, the first maximum traction force may be at least 10% greater than the second maximum traction force, preferably at least 20%, and more preferably at least 50%.

[0054] As mentioned earlier, the first function can be "push in the closing element". The second function can be either "pull out the latch" or "release the pawl". The figure shows a combination of pushing in and pulling out.

[0055] The alternative design provides a primary function of "pull out the latch" and / or a secondary function of "release the pawl".

[0056] Similarly, it was found that, in this case, and preferably, the second flexible traction device 14 twists more frequently and / or over a larger range of angles than the first flexible traction device 13. Here, only the second flexible traction device 14 is twisted once.

[0057] Preferably, the friction loss of the second flexible traction device 14 is at least 2%, more preferably at least 5%, more preferably at least 10%, and even more preferably at least 20%, greater than the friction loss of the first flexible traction device 13. The friction loss can be determined by applying a force to the ends of the flexible traction devices 11 and 12 near the actuator and determining which portion of the force reaches the corresponding ends away from the actuator. For comparison, the same force is applied to both flexible traction devices 11 and 12.

[0058] As can also be seen from the figure, here and preferably, the motor 11 can generate motor movement in the first motor direction and the second motor direction. The motor movement in the first motor direction generates the traction movement of the first flexible traction device 13, thereby triggering the first function, and the motor movement in the second motor direction generates the traction movement of the second flexible traction device 14, thereby triggering the second function.

[0059] The push-in function is considered first. In this case, preferably, the vehicle lock assembly 1 has a push-in component for pushing the closing element 3 into the gap position. The push-in component has a push-in element 16, which in this case is preferably linearly adjustable and / or designed as a slider for pushing the closing element 3 into the gap position. Then, the "push-in closing element" function is to adjust the closing element 3 to the gap position.

[0060] In this configuration, when the pushing element 16 pushes the closing element 3 into the gap position, the pushing element 16 is preferably supported on the vehicle body 2. Figure 1 b) and c) Figure 1 (a) This shows the function of the pushed-in component 16. In this case... Figure 1 The vehicle locks 5 in a) through c) are shown in the same direction. If the push-in element 16 is adjusted linearly to the left, it presses against the vehicle body, thereby pushing in the side door. The user can engage in the engagement gap created in the gap position and manually further open the closing element 3.

[0061] Typically, when the latch 7 is in the pre-closed position, a gap of less than 10 mm, preferably about 6 mm, is maintained between the closing element 3 and the vehicle body 2 when viewed in the opening direction. Therefore, this gap is precisely sized to prevent the user's hand from gripping it from behind, which would pose a considerable risk of getting stuck.

[0062] Preferably, the pre-closed position of the closure element 3 is located between the main closed position and the gap position of the closure element 3. This means that the engagement gap returning to the gap position of the closure element 3 is greater than the aforementioned gap between the closure element 3 and the vehicle body 2 corresponding to the pre-closed position. The gap width of the engagement gap is preferably greater than 18 mm, more preferably greater than 22 mm. In a particularly preferred design, the gap width of the engagement gap is between approximately 26 mm and approximately 31 mm. These values ​​have proven advantageous, especially for the user's hand engaging from behind the engagement gap.

[0063] To perform the "push-in closing element" function, motor 11 here, and preferably in the first motor direction, generates motor movement, which produces traction movement of the first flexible traction device 13. The first flexible traction device 13 then adjusts the pushing element 16 in the pushing direction, thereby pushing the closing element 3 into the gap position. The pushing of the closing element 3... Figure 2 As shown in, Figure 3 Starting from the middle position, in Figure 4 As shown in the diagram. During the pushing operation, it is pulled here and preferably on the first flexible traction device 13, whereby the first flexible traction device 13 pulls the pushing element 16 and adjusts the pushing element 16 in the direction of the vehicle body 2. Here, the maximum pushing force of the pushing element 16 is preferably at least 800 N, and more preferably at least 1000 N.

[0064] It can be seen that, in this case, preferably, the pushing direction of the pushing element 16 is linear. Additionally or alternatively, and preferably here, the pushing element 16 is constructed separately from the locking tongue 7. The stroke of the pushing element 16 and therefore the first flexible traction device 13 can be at least 30 mm, preferably at least 40 mm, more preferably at least or about 50 mm. The stroke is preferably at most 150 mm, more preferably at most 100 mm.

[0065] Special reference Figure 2 and Figure 3 Preferably, a motor 11 is provided to generate motor motion in a first motor direction to perform a "pawl release" function, which generates a traction motion of a first flexible traction device 13, thereby adjusting the pawl 8 in the opening direction to release the pawl 8. Therefore, it is preferable that the release and insertion are performed mechanically synchronously. This can be achieved... Figure 3 As seen in the image. Preferably, during the "push-in closing element" function, the push-in element 16 transmits motion to the pawl 8 to disengage the pawl 8, wherein, preferably, the push-in element 16 has a follower profile 17 by means of which the push-in element 16 disengages the pawl 8.

[0066] Therefore, preferably, the follower profile 17 acts directly on the pawl 8 or directly on the element fixedly connected to the pawl 8. Particularly preferred is that the pawl 8 has a metal core and a plastic part fixedly connected to the metal core, and the follower profile 17 acts directly on the plastic part.

[0067] In particular, from Figures 2 to 4 It can also be seen that, here and preferably during the insertion, the pushing element 16 passes through the first moving portion (from... Figures 2 to 3 ) and the subsequent second movement section (from Figures 3 to 4 In the first movement section, the pushing element 16 disengages the pawl 8 without pushing in the closing element 3, and in the second movement section, the pushing element 16 pushes in the closing element 3.

[0068] For example, from Figure 4 As can be seen, and preferably, in this case, after the pawl 8 is disengaged, the push-in element 16 holds the pawl 8 in the released position. Therefore, the latch 7 and the closing portion 9 can move freely. Preferably, the push-in element 16 only releases the pawl 8 from the released position when it is reset in reverse operation, particularly by the motor 11. According to the design, this function is referred to as the snow load function.

[0069] During the push-in operation, here and preferably first the follower profile 17 acts on the pawl 8 ( Figures 2 to 3 Then, during the push-in operation, the support profile 18, which is functionally separate from the follower profile 17, acts on the pawl 8. Figure 4 ).

[0070] The follower profile 17 is preferably shown at least partially in the pushing direction of the pusher element 16, and is particularly arranged transversely to the pushing direction of the pusher element 16. Here, the follower profile 17 is arranged orthogonally to the pushing direction. During the pivoting of the pawl 8, the extension 19 of the pawl 8 moves along the follower profile 17 until the latter finally leaves the follower profile 17 and no longer adjusts along the pushing direction, but is supported only orthogonally to the pushing direction, in this case upward. Therefore, the support profile 18 preferably extends along the pushing direction of the pusher element 16. During the reverse operation, the pawl 8 runs along the support profile 18 and then falls into the follower profile 17, resulting in the release of the retraction of the pawl 8 during further rearward adjustment of the pusher element 16.

[0071] Generally, the contour change occurs here, and preferably, the pawl 8 changes back and forth between the two contours of the push-in element 16.

[0072] Furthermore, it is preferably provided here that the push element 16 is in the zero position before the push-in operation begins, and when the push element 16 is in the zero position, the pawl 8 can be freely disengaged relative to the push element 16, particularly through mechanical redundancy. Compared to the follower profile 17, the push element 16 has a ramp 20, which provides sufficient space for the pawl 8 to be disengaged. Of course, this does not require the ramp 20; any other flywheel, especially simply having enough space, would suffice.

[0073] Furthermore, in this case, preferably, the push element 16 can return to the zero position after the push operation, while the pawl 8 does not retract. If the pawl 8 has not retracted during the reverse operation, because it rests against the latch 7 and is still in the open position, the extension 19 of the pawl 8 remains below the follower profile 17, and the push element 16 can move freely.

[0074] Regarding from Figures 2 to 5 The transition here, and preferably, provides that motor 11 generates motor movement in the second motor direction to perform the "pull out latch" function, which generates the traction movement of the second flexible traction device 14, thereby adjusting the latch 7 in the closing direction, thus pulling out the latch 7, particularly from the pre-closed position and / or the main closed position. The stroke of the second flexible traction device 14 during the pull-out process can be 20 to 40 mm, preferably about 25 mm.

[0075] As can be seen at least from the perspective view, the motor 11 and / or the push-in element 16 can form a separately operating structural unit with the vehicle lock 5. This structural unit can then be assembled as follows. Preferably, the vehicle lock 5 and the motor 11 and / or the vehicle lock 5 and the push-in element 16 are carried by a common carrier, particularly a carrier plate. The common carrier can be, for example, the carrier of the door module.

[0076] In a preferred design, the vehicle lock 5 has a housing 21 on which the motor 11 and / or the push-in element 16 are arranged. Of course, the housing 21 can also be arranged independently. Here, and preferably, the first flexible traction device 13 and / or the second flexible traction device 14 are arranged entirely or at least more than 50% of their length within the housing 21. This arrangement is particularly compact and takes advantage of the flexibility in placing the motor 11. Furthermore, it can be provided that when the push-in element 16 is pushed in, the push-in element 16 is removed from the housing 21 of the vehicle lock 5.

[0077] As can be seen from the figure, and preferably, the first flexible traction device 13 and the second flexible traction device 14 are coupled to the motor 11 in such a way that when motor movement occurs in the first motor direction, the first flexible traction device 13 is rolled up and the second flexible traction device 14 is unfolded. When motor movement occurs in the second motor direction, the situation is reversed accordingly.

[0078] Preferably, the first flexible traction device 13 and / or the second flexible traction device 14 are wound onto a winding shaft 22 during their movement, particularly on the same winding shaft 22 and unwound from the winding shaft 22. The first flexible traction device 13 and / or the second flexible traction device 14 are preferably wound onto the winding shaft 22 in multiple layers. Additionally or alternatively, the winding shaft 22 is coaxial with the motor shaft 23 of the motor 11; in particular, the winding shaft 22 is the motor shaft 23 itself, an extension of the motor shaft 23, or an accessory on the motor shaft 23. It is conceivable that the winding radii of the flexible traction devices 11 and 12 can be the same or different. Different winding shafts 22 are also conceivable.

[0079] It should be noted that the windings of the flexible traction devices 11 and 12 are not included in the calculation of deflection and deflection angle. The so-called torsion is not deflection.

[0080] Furthermore, a first flexible traction device 13 is preferably provided here, which is directly fastened to the push-in element 16 at the fastening point 24. The first flexible traction device 13 preferably extends from the fastening point 24 along the push-in direction of the push-in element 16, and preferably subsequently deflects once. For this purpose, a deflection roller 25 is preferably provided.

[0081] In this case, and preferably, the motor 11 is designed to be self-locking. Preferably, the motor 11 has a transmission device 12 with a self-locking design. Therefore, at the end of the push-in, the motor 11 can switch to passive mode, specifically without current, and due to the self-locking of the motor 11, the pushing element 16 remains in the end position of the push-in operation, so that the closing element 3 remains in the gap position.

[0082] The figure shows a second flexible traction device 14 here, and preferably fastened to the pull rod 26 for the locking tongue 7. Optionally, the second flexible traction device 14 can be fastened to the locking tongue 7. The second flexible traction device 14 preferably deflects at least once, preferably multiple times. The second flexible traction device 14 and / or the first flexible traction device 13 can deflect on elements fixed to the housing, particularly nails. This is particularly easy to achieve. In this case, preferably, the second flexible traction device 14 twists between two deflections. This demonstrates a high degree of flexibility in guiding the flexible traction devices 11, 12 through the vehicle lock 5. Additionally or alternatively, twisting can also be provided in the first flexible traction device 13.

[0083] Here, and preferably further, the drive assembly 10 has a zero position, specifically the zero position of the motor shaft 23. This zero position corresponds to... Figure 2 After performing the "pull out the pawl" and / or "pull out the latch" and / or "push in the closing element" functions, the drive assembly 10 is reset to the zero position. Furthermore, the drive assembly 10 starts performing the "pull out the pawl" and / or "pull out the latch" and / or "push in the closing element" functions from the zero position. Preferably, as... Figure 2 As shown, the first flexible traction device 13 and / or the second flexible traction device 14 are pre-wound on the winding shaft 22 at the zero position.

[0084] It can be provided that the motor vehicle lock assembly 1 has a switch for detecting the zero position of the push-in element 16 and / or a switch for detecting the push-in position of the push-in element 16, and the motor 11 is operated during one of the functions based on signals from one or more switches, in particular to terminate the function.

[0085] from Figure 2 It can also be seen that when one of the flexible traction devices 11 and 12 is rolled up, the other is unrolled. Accordingly, the other flexible traction device 11 or 12 is fully pre-rolled at the zero position so that it can be unrolled far enough. A guide device for unrolling one or both of the flexible traction devices 11 and 12 can be provided, which specifically prevents the corresponding flexible traction device 11 or 12 from occupying an uncontrolled position during unrolling. The guide device can be provided, for example, on the side of the flexible traction device 11 or 12, so that unrolling is preferably guided in a reproducible manner. Additionally or alternatively, a belt tensioner can be provided for one or both of the flexible traction devices 11 and 12. The belt tensioner tensions the flexible traction device 11 or 12 during unrolling and can be provided, for example, by the leg of a spring, which is also preferably used elsewhere. Thus, the corresponding flexible traction device 11 or 12 is also guided in a reproducible manner.

[0086] To avoid the need for the flexible traction devices 11 and 12 to be pre-wound further, the first flexible traction device 13 and / or the second flexible traction device 14 can be provided to flip during at least one of the "pulling out pawl," "pulling out latch," and "pulling in closing element" functions on the winding shaft 22. This variation can be explained by an exemplary stroke of 50 mm during pushing in and 25 mm during pulling out. During pushing in, the first flexible traction device 13 is wound up, and the second flexible traction device 14 unfolds accordingly. For this purpose, the second flexible traction device 14 must also allow a 50 mm stroke during unfolding. It is conceivable to pre-wound the second flexible traction device 14 by 50 mm. However, it is also possible to pre-wound the second flexible traction device 14 by only about 25 mm, with tolerances added if necessary. Then, the second flexible traction device 14 unfolds, for example, by 25 mm, flips, and winds up again by 25 mm, while the first flexible traction device 13 performs the 50 mm stroke. Meanwhile, the second flexible traction device 14 does not act on the pull-out rod 26. This flipping results in fewer flexible traction devices 11, 12 becoming free when unfolded, requiring fewer flexible traction devices 11, 12, and reducing the winding radius of the flexible traction devices 11, 12, thereby improving efficiency.

[0087] Therefore, it is hereby provided, and preferably, that the first flexible traction device 13 and / or the second flexible traction device 14 are pre-wound between 50% and 90% of the maximum stroke of the respective other flexible traction device 11, 12, preferably between 60% and 80%.

[0088] Preferably, the first flexible traction device 13 flips during the "pull out the latch" function, and / or the second flexible traction device 14 flips onto the winding shaft 22 during the "pull out the pawl" and / or "push in the closing element" functions.

[0089] The push-in element 16 can be spring-driven reset after being pushed in and / or the pull-out rod 26 after being pulled out and / or the pawl 8 after being pulled out, preferably simultaneously resetting the drive assembly 10 to the zero position. Due to self-locking, the motor 11 preferably rotates in the opposite direction to the motor assigned to the corresponding function.

[0090] Alternatively or additionally, a second flexible traction device 14 may be provided, which also cooperates with the push-in element 16. Figure 6 This variation is illustrated. Preferably, the second flexible traction device 14 resets the pushing element 16, particularly when the motor 11 produces motor movement in the second motor direction. Additionally or alternatively, and also in… Figure 6In this configuration, when the second flexible traction device unfolds during the "push-in closing element" function, the pushing element 16 tensions the second flexible traction device 14. Through proper coordination, on the one hand, excessive free space can be prevented in the second flexible traction device 14 during the stroke of the pushing element 16; on the other hand, the return spring for the pushing element 16 can be omitted. In this case, the second flexible traction device 14 preferably does not flip. However, for the first configuration, flipping can be further provided.

[0091] Typically, and preferably here, the first flexible traction device 13 and / or the second flexible traction device 14 are belts and / or unsheathed. Sheaths, as in Bolton cables, reduce the flexibility of the flexible traction devices 11, 12, but increase their resistance to external influences. A single belt can also be flexibly placed at several corners and has high stability.

[0092] Preferably, the width of the first flexible traction device 13 and / or the second flexible traction device 14 is at least 1.5 times, more preferably at least 4 times, and more preferably at least 8 times, the thickness of the corresponding flexible traction devices 11, 12. Herein and preferably, the thickness of the first flexible traction device 13 and / or the second flexible traction device 14 is between 0.5 mm and 1.5 mm, in this case 1 mm, and / or the width is between 6 mm and 14 mm, preferably between 8 mm and 12 mm, in this case 10 mm. The width and thickness are arranged orthogonally to the longitudinal direction. Additionally or alternatively, the first flexible traction device 13 and / or the second flexible traction device 14 may be provided with an elliptical or rectangular cross-section. The cross-section must also be orthogonal to the longitudinal direction. The first flexible traction device 13 and / or the second flexible traction device 14 may be made of textile material.

[0093] Furthermore, the vehicle lock assembly 1, particularly the vehicle lock 5, is preferably provided here with a control unit that operates the motor 11 according to its function and / or the application of that function to provide different output powers, for example by means of PWM (Pulse Width Modulation). The control unit may be arranged in the housing 21. When pushed in, a force of 100 to 300 N, such as 150 N, is generally preferably provided. In the case of icing of the sealing element 3, a force of 400 to 700 N, such as 500 N, is preferably provided. After a collision, for example by reporting via a collision signal, a force of at least 800 N, such as at least 1000 N, is preferably provided. During the pull-out process, a force of 400 N is preferably provided. In this case, the force is always associated with the flexible traction devices 11, 12 behind the winding shaft 22 and before wear.

[0094] The drive assembly 10 may have a PWM drive stage for driving the motor 11 with PWM. Electrical connections may be provided in the form of a stamped mesh, which may be embedded in the housing 21. The control unit may include a microprocessor. The operating voltage of the motor 11 may be less than or equal to 48 V. The motor 11 may be a DC motor and / or have brushes or be brushless. The motor 11 may have copper windings.

[0095] According to another teaching, a functional component 27 for a motor vehicle 4 is proposed, wherein the functional component 27 includes a drive assembly 10 having a motor 11, wherein the drive assembly 10 includes a first flexible traction device 13, wherein the motor 11 can act on the first flexible traction device 13 to trigger a first function of the motor vehicle 4, specifically a first function of the functional component 27, wherein the functional component 27 is configured to trigger the first function with a first maximum traction force of the first flexible traction device 13. According to this teaching, the drive assembly 10 has a second flexible traction device 14, and the motor 11 can act on the second flexible traction device 14 to trigger a second function of the motor vehicle 4, specifically the functional component 27, which is configured to trigger the second function with a second maximum traction force of the second flexible traction device 14, the second flexible traction device 14 deflecting at least once, and the second flexible traction device 14 deflecting more frequently and / or with a larger deflection angle range than the first flexible traction device 13. The second maximum traction force is preferably less than the first maximum traction force.

[0096] All implementation schemes of the proposed motor vehicle lock assembly 1 can be referenced.
