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 a first electric motor drive at least for opening the locking mechanism and for acting on a first coupling element, and with a second electromotive drive for acting on a second coupling element.
  • 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.
  • electric motor drives are often used to open the locking mechanism, i.e. electric motor opening drives. These are increasingly being used for comfort and acoustic reasons.
  • the locking mechanism consisting of a rotary latch and a pawl can be opened. To do this, the pawl is lifted from its locking engagement with the rotary latch using the electric motor drive. As a result, the rotary latch opens with spring support and releases a previously caught locking bolt and thus the associated motor vehicle door.
  • the locking mechanism can be opened Emergency measures required. This includes, for example, the emergency opening of an operating lever chain in the event of a crash.
  • the actuating lever chain in question is transferred to its “unlocked” position, which generally includes the “engaged” state of the coupling element.
  • the operating lever chain is closed so that, for example, arriving rescue personnel can open an associated motor vehicle door using an outside door handle. This process is known as “temporary crash redundancy (TCR)”.
  • the operating lever chain in question is generally open during normal operation. This is so that, for example, while driving or even if the motor vehicle is stopped for a short time, the associated motor vehicle door cannot be opened from the outside by unauthorized persons (for example at a red light).
  • the electric motor drive now ensures electric opening.
  • the operating lever chain must be closed mechanically in order to enable a mechanically redundant opening of the locking mechanism. This can be done using the first electric motor drive or the second electric motor drive.
  • the procedure is such that the electric motor drive works on the locking mechanism for opening in one opening direction and in one of these A safety lever is acted upon in a different unlocking direction to assume its unlocking position.
  • a stop is provided for the electric motor drive, which limits the movement of the electric motor drive at least when it is acted upon in the opening direction to cancel the unlocking position. This prevents the lock from opening.
  • 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 operation is easier overall and electric motor opening is possible without any problems and at any time.
  • the invention proposes in a generic motor vehicle lock and in particular a motor vehicle door lock that the first electric motor drive when opening the locking mechanism simultaneously works on a blocking slide acting on the second coupling element in the sense of a freewheel.
  • the first electric motor drive when the locking mechanism is opened using the first electric motor drive, any possible blockages in a second operating lever chain, which usually belongs to the second coupling element, are automatically released and released in the sense of a freewheel.
  • the first electric motor drive which is typically assigned to the first operating lever chain, also ensures that any blockages in the second operating lever chain are removed in the sense of freewheeling when the locking mechanism is opened.
  • the first operating lever chain is generally an external operating lever chain. Consequently, the first electric motor drive ensures, on the one hand, that the locking mechanism is opened and, on the other hand, that the first coupling element can be acted upon as part of this first operating lever chain or external operating lever chain. If the electromotive opening described occurs, the first electromotive drive when opening the locking mechanism usually works not only on a release lever but also on the second coupling element as part of the second operating lever chain or internal operating lever chain. Because in the described opening process of the locking mechanism, the first electric motor drive ensures that a blocking slide as part of the second operating lever chain is acted upon with its help in the sense of freewheeling. The blocking slide for its part generally works on the second coupling element as part of the second operating lever chain or internal operating lever chain.
  • this design ensures that when the locking mechanism is opened electromotively using the first electromotive drive, any blockages in the second operating lever chain and in particular the internal operating lever chain are overcome in the sense of a freewheel.
  • this is according to the invention and is harmless when the locking mechanism is opened using the first electric motor drive, because the first electric motor drive also ensures the desired freewheeling in the second operating lever chain, that is, any blockage of the electric motor drive by the pulled or pressurized internal operating lever is canceled. This is where the main advantages can be seen.
  • the first electric motor drive usually has an actuating element with at least one freewheel arm.
  • the freewheel arm can interact with an attachment on the blockage slide. As soon as the freewheel arm moves against the approach on the blocking slide in connection with the opening of the locking mechanism by acting on the first electromotive drive, this leads to the blocking slide being pivoted out of its position blocking the electromotive opening process or the second actuating lever chain.
  • the blocking slide typically has a blocking nose for an actuating lever equipped with the second coupling element.
  • the blocking nose lies against a blocking contour of the actuating lever. That is, if the actuating lever in question is deflected or acted upon as part of the second actuating lever chain, a blockage occurs between the blocking contour on the relevant actuating lever and the blocking nose on the blocking slide.
  • this blockage is resolved as soon as the first electric motor drive is actuated to open the locking mechanism and releases the blockage by simultaneously acting on the blockage slide. If there is no blockage, it is of course not necessary for the missing blockage to be removed or to be removed using the first electric motor drive when the lock is opened.
  • the first electric motor drive ensures that the blocking slide, as part of the second actuating lever chain and for acting on the second coupling element, is released from its possibly occupied blocking position.
  • the blocking slide rests with its blocking nose on the blocking contour of the actuating lever in question as part of the second actuating lever chain.
  • the operating lever in question as a component of the second operating lever chain is typically an internal operating lever as a component of the second operating lever chain or internal operating lever chain already mentioned.
  • the first coupling element as part of the first actuation lever chain or external actuation lever chain can be optionally transferred to the “engaged” and “disengaged” positions.
  • the “engaged” position of the first coupling element corresponds to the fact that the first operating lever chain or external operating lever chain is mechanically closed.
  • the “disengaged” position of the first coupling element corresponds to the fact that the first operating lever chain or external operating lever chain in question is mechanically opened.
  • the actuating element of the first electric motor drive is usually equipped with a pin to act on the attachment on the blocking slide.
  • the pin generally works in one direction of rotation of the actuating element on a release lever and in the other direction of rotation of the actuating element on a transmission lever that controls the first coupling element.
  • the first electric motor drive ensures in one direction of rotation that the release lever is acted upon via the pin on the actuating element.
  • the locking mechanism can be opened using the activated release lever. This is because the release lever lifts the pawl from its engagement with the rotary latch in the closed position of the locking mechanism.
  • the pin on the actuating element ensures that the transmission lever controlling the first coupling element and the first coupling element are acted upon.
  • the blockage slide is generally equipped with a spring that acts on it to take its basic position. Since the blocking slide is acted upon in the sense of freewheeling during an electromotive opening process and an additional blocking of the actuating lever or internal actuating lever of the second actuating lever chain or internal actuating lever chain, this means that the spring is compressed during the relevant freewheeling of the blocking slide. After freewheeling has ended, the spring ensures that the blocking slide is moved back to its basic position.
  • a motor vehicle lock and in particular a motor vehicle door lock is provided and implemented, which enables perfect electromotive opening even if the second operating lever chain is, for example, manually acted upon and this would normally lead to a blockage of the first electromotive drive.
  • the first electric motor drive simultaneously acts on a blocking slide acting on the second coupling element as part of the second operating lever chain or internal operating lever chain in the sense of freewheeling .
  • a motor vehicle lock is shown in the single FIG. 1, which is designed as a motor vehicle door lock.
  • the motor vehicle lock in question has a locking mechanism 1, 2 consisting essentially of a rotary latch 1 and a pawl 2, which is shown schematically in the closed position.
  • the locking mechanism 1, 2 extends in a plane perpendicular to the plane of the drawing.
  • the action on a release lever 3 about its axis in the clockwise direction indicated in FIG. 1 now results in the pawl 2 being lifted from its latching engagement with the rotary latch 1.
  • the rotary latch 1 then opens with spring support and releases a previously caught locking bolt and thus the associated motor vehicle door.
  • a first step is to do so electric motor drive 4, 5, 6 realized.
  • the first electric motor drive 4, 5, 6 is composed of an electric motor 4, a downstream transmission 5 and an actuating element 6 on the output side.
  • the release lever 3 can now be pivoted about its axis in the direction of the clockwise movement described.
  • the actuating element 6 performs a counterclockwise rotation movement indicated in FIG. 1.
  • the first electric motor drive 4, 5, 6 already described is not only set up and designed at least for opening the locking mechanism 1, 2. Rather, according to the exemplary embodiment, the first electric motor drive 4, 5, 6 in question is also able and designed to act on a first coupling element 7.
  • the first coupling element 7 belongs to a first actuation lever chain 7, 8, which, in addition to the first coupling element 7, also has an actuation lever or external actuation lever 8.
  • the first coupling element 7 is rotatably mounted on the actuating lever 8.
  • the operating lever or external operating lever 8 is in turn rotatably arranged on the same axis as the release lever 3.
  • a transmission lever 9 mounted on a housing is implemented to act on the first coupling element 7. If the actuating element 6 is acted upon in a clockwise direction using the electric motor drive 4, 5, 6, the pin 6a on the actuating element 6 ensures that the transmission lever 9 is pivoted about its axis in the counterclockwise direction and thereby the first coupling element 7 is moved with its pin indicated in FIG. 1 along a recess into the lowest position within this recess. As a result, the coupling element 7 comes with a front edge 7a into engagement with a stop 3b on the release lever 3.
  • the first electric motor drive 4, 5, 6 can be acted upon in a first direction in order to open the locking mechanism 1, 2. This includes a counterclockwise rotation of the adjusting element 6, which results in the release lever 3 being pivoted clockwise via the pin 6a and the actuating arm 3a.
  • the actuating element 6 is acted upon in the other direction of actuation, i.e. H. clockwise, this results in the first coupling element 7 being “coupled” using the first electric motor drive 4, 5, 6.
