Definitions

  • the invention relates to a motor vehicle lock, in particular a motor vehicle door lock, with a locking mechanism consisting essentially of a rotary latch and pawl, furthermore with an electromotive drive and with a safety element acted upon by the drive.
  • Motor vehicle locks are used in many different forms and in different variations in and on the motor vehicle.
  • Motor vehicle door locks in or on motor vehicle doors are observed and implemented by way of example.
  • these include tailgate locks, front hood locks, tank flap locks, etc.
  • seat locks are also equipped with motor vehicle locks.
  • Motor vehicle door locks can assume different security positions, which are implemented and implemented with the help of the security element.
  • the securing element may not be a locking element in a restrictive manner.
  • the locking element can assume functional positions such as “locked”, “unlocked” but also “theft-protected” and “theft-unlocked”.
  • additional functional positions such as “child-safe” and “child-unlocked” are implemented and implemented, in particular on rear side doors with the help of such safety elements or locking elements.
  • this is often done with recourse to the electric motor drive, which, by acting on the safety element, ensures that the previously specified functional positions, ie generally "unlocked” or "secured", are assumed.
  • the generic DE 10 2017 106 707 A1 proceeded so that a coupling element there interacts with a drive element of the drive.
  • the coupling element can be moved into different positions such as “locked”, “unlocked” and “theft-proof and child-proof”.
  • the coupling element is closed to the drive element in order to assume its position.
  • the drive element can in turn be controlled mechanically and / or electrically into the different positions.
  • the respective change of position takes place either purely mechanically or purely electrically. In this way, the number of drives required is reduced overall and cost and weight advantages can be observed at the same time.
  • the invention is based on the technical problem of further developing such a motor vehicle lock and in particular a motor vehicle door lock so that that the design and financial outlay are reduced while at the same time functioning properly.
  • the invention proposes in a generic motor vehicle lock that the securing element is designed in two parts with a securing lever and a securing transmission lever, both levers being mechanically coupled in the securing direction to take a securing position with the aid of the drive and mechanically decoupled in the opposite direction.
  • the invention thus initially relies on a two-part securing element.
  • This is made up of the safety lever and the safety transmission lever.
  • the safety transmission lever interacts with the drive.
  • the drive regularly works on the security transmission lever and in this way ensures that the security position is assumed.
  • Both levers are mechanically coupled with the aid of the drive in order to assume this locking position in the locking direction.
  • the mechanical coupling of the two levers in this safety direction ensures that during this process the safety transfer lever "secures the safety lever in the desired position"", in this case in the" childproof "position, blocked.
  • the "child-proof” function coincides with the "theft-proof” function through the mechanical coupling of the two levers, so that in this case the mechanical actuation chains are disabled for mechanical opening from the inside as well as from the outside electrical opening, ie opening by a separate control of a motor, remains possible.
  • the two levers are mechanically decoupled in the opposite direction.
  • This opposite direction to the securing direction consequently corresponds to the unlocking direction.
  • the electromotive drive - as described - usually acts on the safety transmission lever to take up the safety position and rests against it, the mechanical decoupling of the two levers in the opposite direction and consequently the unlocking direction ensures that the safety lever is the one previously assumed with the aid of the drive Can leave the "secured" position.
  • the reversing electromotive opening drive ensures that the safety lever, as part of the two-part safety element, is moved into the "unlocked” position.
  • the safety transfer lever and the electromotive drive for the safety element are not affected by this.
  • Assuming the "unlocked" position of the safety lever now has the consequence that the actuating lever chain previously opened in normal operation is closed and the desired emergency opening of the locking mechanism can take place via the actuating lever chain that is then closed. This is where the main advantages can be seen.
  • both levers are mechanically coupled via a driving contour that acts on one side in each case in order to assume the locking position. That is, the entrainment contour is designed such that the two levers, that is to say the securing lever and the securing transmission lever, are mechanically connected to one another in the securing direction.
  • the two levers are mechanical in the opposite direction or unlocking direction separated from each other and in particular the safety lever can be transferred from its previously assumed “secured” position to the "unlocked” position independently of the safety transfer lever. This applies even if the safety transmission lever is blocked with the aid of the electric motor drive.
  • a particularly compact and inexpensive embodiment variant is characterized in that both levers, that is to say the safety lever and the safety transmission lever, are mounted coaxially to one another.
  • the electromotive drive advantageously has a reversible drive worm.
  • this reversible drive worm With the help of this reversible drive worm, the two positions “secured” and “unlocked” of the two-part safety element can be implemented.
  • the drive worm is generally equipped in a semicircular shape with two end-side cams.
  • One of the two cams is typically designed as a transmission lever cam and the other cam as a clutch lever cam.
  • the transmission lever cam generally interacts with a blocking contour on the safety transmission lever.
  • the clutch lever cam generally engages in a recess of a clutch lever or a connecting lever.
  • the transfer lever cam moves into the pivoting path of the safety transfer lever and blocks any pivoting of the safety transfer lever there.
  • the clutch lever cam holds the clutch lever or connecting lever in place to assume the safety position.
  • the clutch lever or connecting lever regularly belongs to an internal actuation lever chain, so that an internal actuation lever is also empty as a result.
  • the safety position for emergency operation or emergency actuation allows a pivoting movement of the safety lever from its "secured” position into the "unlocked” position.
  • the electromotive opening drive - as described - may take care of this.
  • an external actuation lever chain is typically closed, so that the associated motor vehicle door can still be opened via an external actuation lever for emergency opening and following such a crash or failure of the battery.
  • the essential functional positions of the motor vehicle lock and in particular positions such as "theft-protected”, “theft-unlocked” or “child-safe” and “child-unlocked” on a rear motor vehicle side door can be implemented with particularly little effort.
  • the typically required temporary crash redundancy can be realized and implemented, because despite taking the "secured” position and thus the ineffective internal operating lever in the example case, the safety lever can still be actuated in the unlocking direction and assumes the "unlocked" position.
  • the unlocked safety lever ensures that, in general, an external operating lever chain is closed that was previously and continuously open.
  • the desired emergency opening of the motor vehicle door can now take place from the outside via this external operating lever chain and an external operating lever. This is where the main advantages can be seen.
  • a motor vehicle lock is shown, which in the present case is designed as a motor vehicle door lock.
  • the motor vehicle door lock is provided on a rear side door of a motor vehicle according to the example and not by way of limitation.
  • the motor vehicle door lock is in the position "central locking inserted" and “theft unlocked” or “child unlocked”, which coincide in this case, shown and reproduced. This means that the motor vehicle door lock can be opened from the inside via an internal actuating lever and an (internal) actuating lever chain.
  • opening from the outside is not provided because of the implemented TCR function and by assuming the functional position "locked" of the associated (external) operating lever chain in normal operation. Rather, the opening takes place electrically with the aid of an electromotive opening drive 1, 2, 3. Only in the event of an emergency opening does the TCR mode ensure that the (external) operating lever chain is closed and an external operating lever can work on a locking mechanism, not shown in detail, from essentially rotary latch and pawl.
  • the above-mentioned locking mechanism consisting essentially of a rotary latch and a pawl, is acted upon with the aid of the electromotive opening drive 1, 2, 3.
  • the opening drive 1, 2, 3 in question has an electric motor 1, an output worm 2 arranged on an output shaft and a reversible output pulley 3 which meshes with the output worm 2.
  • a counterclockwise rotation of the output disk 3 of the electromotive opening drive 1, 2, 3 corresponds to the fact that the locking mechanism, which is not expressly shown, is opened in a known manner via a cam provided on the rear of the output disk 3, either indirectly or directly with the interposition of a release lever, which is also not shown becomes.
  • a clockwise movement of the output disk 3 corresponds to the fact that a cam 4 provided on the output disk 3 interacts with a stop contour 5 of a safety lever 6, which as a result of this clockwise rotation of the output disk 3 in the Fig. 1 indicated counterclockwise about its axis 7 is pivoted.
  • the securing lever 6, together with a securing transmission lever 8, defines according to the invention a two-part securing element 6, 8 which, according to the exemplary embodiment, can be pivoted about the axis 7 common to both levers 6, 8. Because in the context of the example shown, both levers 6, 8 are mounted coaxially to one another, namely have the corresponding axis 7.
  • the basic structure then includes a further electromotive drive 9, 10, 11, which, in contrast to the electromotive opening drive 1, 2, 3, functions as a safety drive 9, 10, 11 and, among other things, with the two-part safety element 6, 8 mentioned above interacts.
  • the safety drive 9, 10, 11 in turn consists of an electric motor 9, an output worm 10 on an output shaft of the electric motor 9 and an output pulley 11 meshing with the output worm 10, which can perform reversing movements around its axis.
  • the design is such that the securing element 6, 8 is not only designed in two parts with the securing lever 6 and the securing transmission lever 8. But both levers 6, 8 are also to take one in the Fig. 1 and 3A , 3B
  • the locking position shown is mechanically coupled to one another with the aid of the drive or locking drive 9, 10, 11.
  • an unlocking direction E belongs to a rotational movement of the driven pulley 11 in the counterclockwise direction, like the Figure 2A indicates.
  • the two levers 6, 8 of the two-part securing element 6, 8 are coupled to one another via an entrainment contour 12 that acts on one side in each case. If the fuse element 6, 8 in the Figure 2A and 2 B position shown "central locking engaged" assumes, in the context of the exemplary embodiment, an internal operating lever can be in the Fig. 1 apply to the clutch lever 14 to be recognized, which in turn opens the locking mechanism. At the same time, the internal operating lever actuates a spring 13, which is designed as a leg spring and which engages around the safety transmission lever 8.
  • the safety transfer lever 8 has a driving contour 12, by means of which it takes the safety lever 6 with it and moves it into the "unlocked” position, like an arrow in the counterclockwise direction Figure 2B indicates if the securing element 6, 8 has not already assumed the "unlocked” position from the outset. This enables a so-called “override” function, that is to say actuation of the internal actuation lever at the same time ensures that the securing element 6, 8 assumes its "unlocked” position - if necessary.
  • the transfer lever cam 15 interacts with a blocking contour 8a of the safety transfer lever 8.
  • the transfer lever cam 15 is in the "secured” position according to the Figure 3A and 3B at this blocking contour 8a of the safety transmission lever 8.
  • the clutch lever cam 16 engages in a recess in the connecting lever 17 and in this way and in accordance with the illustration in FIG Figure 3A that the clutch lever 14 already mentioned is blocked. Since the clutch lever 14 is blocked, corresponding movements of the internal actuating lever interacting with the clutch lever 14 also go empty, so that in the Figure 3A and 3B "Secured” position shown, opening of the motor vehicle door lock via the internal operating lever is not possible.
  • An “override” cannot be implemented either because the transmission lever cam 15 blocks the safety transmission lever 8.
  • a nut 18 or child safety nut which is connected to the connecting lever 17.
  • the connecting lever 17 can be acted upon independently of the securing drive 9, 10, 11 in order to set the "secured" position according to the illustration in FIG Figure 3A to reach.
  • the connecting lever 17 is in the Figure 3A arrow direction shown moves "down".
  • opening again via the internal actuation lever is avoided and no override is possible either.
  • the safety lever 6 can be unlocked again via the "TCR run" as described.
