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 a pawl, furthermore with an actuating lever chain with at least one actuating lever and a release lever, and with an electric motor drive, which selectively moves a coupling element of the actuating lever chain into its positions “engaged” and “disengaged”.
  • Motor vehicle locks and in particular motor vehicle door locks of the design described above are used in different variants and in a variety of positions in and on a motor vehicle. In fact, this includes, among other things, tailgate locks, front hood locks, fuel filler flap locks and also seat locks. In general, however, the relevant motor vehicle locks and in particular motor vehicle door locks are implemented on motor vehicle side doors.
  • the operating lever chain in question in the example case is generally open during normal operation and thus “locks” the motor vehicle lock, so that the lock cannot be opened using the operating lever chain in said normal operation.
  • the electromotive drive generally ensures the electromotive opening.
  • the coupling element which is acted upon by a separate electric motor drive for this purpose.
  • different drives are implemented for acting on the coupling element on the one hand and for opening by electric motor on the other.
  • the stop is arranged on the electric motor drive and interacts with a blocking element.
  • the blocking element can in turn be arranged on the previously mentioned safety lever. This makes it possible to achieve temporary crash redundancy overall.
  • the invention is based on the technical problem of further developing such a motor vehicle lock and in particular a motor vehicle door lock in such a way that the design effort is reduced compared to the previous state of the art.
  • the invention proposes in a generic motor vehicle lock and in particular a motor vehicle door lock that the coupling element is designed as a link element which is guided in at least one link and either connects or separates a first release lever and a second release lever.
  • a two-part release lever is initially implemented, which has two mechanically separate components, namely the first release lever and the second release lever.
  • the two Trigger levers are advantageously mounted on the same axis as one another.
  • an additional external operating lever is mounted on the common axis of the first release lever and second release lever. Due to the separate design, the first release lever and the second release lever can be acted upon independently of one another.
  • the coupling element is now designed as a link element, which selectively connects or separates the first release lever and the second release lever.
  • the backdrop element is guided in at least one backdrop.
  • the link or the link element can now be acted upon in such a way that the first release lever and the second release lever are connected to one another.
  • the operating lever i.e. H. an external operating lever, an internal operating lever or both, to pivot the two release levers, which are mechanically coupled to one another via the link element, together in order to be able to open the locking mechanism.
  • the electric motor drive is acted upon in such a way that the first release lever and the second release lever are separated from one another, loading of the actuation lever (internal actuation lever and/or external actuation lever) results in only one of the two actuation levers pivoting and the locking mechanism, which is typically in the closed state, being unaffected remains.
  • the actuating lever performs an idle stroke compared to the locking mechanism.
  • the temporary crash redundancy described in the introduction can be implemented.
  • the electric motor drive is designed as a TCR drive. If the electric motor drive in question assumes its functional position “TCR off”, each actuation of the operating lever is idle compared to the locking mechanism.
  • the locking mechanism which is generally in its closed position, cannot therefore be opened. If, on the other hand, the electric motor drive is in its functional state “TCR on”, the locking mechanism can be opened from its closed state using the operating lever (internal operating lever or external operating lever). This applies at least as long as the first release lever and the second release lever are mechanically coupled to one another by the electric motor drive or TCR drive in the example case via the link element guided in the at least one link. As soon as the electric motor drive - again - assumes its functional position “TCR off”, the two release levers are separated from each other again.
  • Such a functionality can be implemented particularly easily in terms of construction because only the link element and at least one link have to be implemented.
  • the link element and the link can be implemented and implemented in an overlapping manner with the already existing levers, so that a particularly compact structure is also observed. Flawless function control is also possible via the backdrop. This is where the main advantages can be seen.
  • the link element is designed as a link block guided in the at least one link.
  • the link itself is generally designed in two parts with a first link on the trigger side and a second link on the drive side.
  • first link is arranged in or on the second release lever, which in turn is or can be acted upon by the actuating lever.
  • second link is usually provided and arranged in a transmission lever that interacts with the drive.
  • the procedure is typically such that the first link formed in or on the second release lever is V-shaped.
  • the second link provided in or on the transmission lever has an arc-shaped character.
  • the electromotive drive is now not only set up to act on the link element, but can also be used to open the locking mechanism by electromotive or electrical means. That is, comparable to the prior art already described in the introduction according to EP 3 800 310 A1, the procedure according to the invention is such that the electric motor drive takes on a dual function.
  • the design is also such that the electric motor drive acts on the transmission lever in one direction of rotation and the first release lever in the other direction of rotation. This means that if the electric motor drive acts on the transmission lever in one direction of rotation, it can be used to move to the previously described functional positions “TCR on” and “TCR off”. In principle, a generally known security function can also be implemented in this way. In this case, the electric motor drive in one direction of rotation ensures that the resulting security unit (locking unit, child safety unit, anti-theft device or combinations thereof) moves from its “secured” or “TCR off” position to the “unlocked” or “TCR” position “a” is transferred. This is ultimately a question of interpretation and terminology.
  • the functional position “secured” means that the actuating lever chain is open because the coupling element or link element assumes its “disengaged” position. If, on the other hand, the functional position “unlocked” is observed, this is the case Coupling element or link element is “coupled” in its position and the actuating lever chain is closed.
  • the electric motor drive can take on the dual function already described. Because in the other direction, the electric motor drive is able to act on the first release lever. Actuating the first release lever now means that the locking mechanism can be opened in all cases. This means that the locking mechanism can be opened electrically using the first release lever at any time, i.e. H. regardless of the additional position of the safety unit or the TCR drive. Only if there is no electrical opening and the actuation lever chain is opened via the actuation lever (internal actuation lever and/or external actuation lever) does the position of the coupling element or link element play a role because the actuation of the actuation lever is carried out via the second release lever. Its mechanical coupling with the first release lever now depends on whether the coupling element or link element opens or separates the actuating lever chain.
  • the electric motor drive is equipped with a pin provided on an actuating element.
  • the pin serves to selectively act on the transmission lever on the one hand or the first release lever on the other hand.
  • the pin is advantageously arranged in the basic position of the motor vehicle lock between the transmission lever and the first release lever. In this way, depending on the pivoting direction of the actuating element and thus the direction of rotation of the electric motor drive, it is easy to differentiate mechanically and functionally between the action on the link element and the electrical opening of the locking mechanism.
  • a motor vehicle lock which is constructed to be functionally reliable and requires only a few components to be implemented and at the same time has a compact structure.
  • an overall cost-effective design is observed because at the same time the electric motor drive takes on and fulfills a dual function in such a way that with its help both an electric motor opening and an actuation of the coupling element or link element is possible.
  • the electric motor drive in question ultimately functions not only as an opening drive for the locking mechanism, but also as a TCR drive or security drive for a realized security unit. This is where the main advantages can be seen.

  • the figures show a motor vehicle lock, which in the exemplary embodiment is a motor vehicle door lock. In its basic structure, this has a locking mechanism 1, 2, which is only indicated in FIG.

  • FIG. 2 This is indicated schematically in FIG. 2 by an arrow, which represents a clockwise rotation associated with the associated pivoting movement of the first release lever 3i.

  • the “engaged” position belongs to the Coupling element or link element 7 to the functional position, as shown in FIGS. 5A and 5B. If, on the other hand, the coupling element or link element 7 assumes its “disengaged” position, this includes the functional position as shown in FIGS. 3A and 3B.
