Definitions

  • the present invention relates to a motor vehicle door lock with a combined Monel- and ⁇ Stammsantrieb with the features of the preamble of claim 1.
  • motor vehicle door lock is to be understood comprehensively, not only side door locks and rear door locks, but, for example, also tailgate locks are covered.
  • the known motor vehicle door lock from which the invention proceeds (EP 0 710 755 B1) initially has the usual closing elements in the form of a latch and a lock latch in the closed position locking pawl and a lock mechanism with a plurality of cooperating and the closing elements, if necessary, actuated elements ,
  • To the elements of the lock mechanism includes a by hand from an outside door handle o. The like.
  • To be actuated external actuating element in the form of a toggle lever which can actuate the pawl via a coupling element in the form of a pivotable and longitudinally displaceable lever in the engaged position. In disengaged, namely swung out of a driving lug in a free chnitted position of the coupling element, the external actuating element performs an idle stroke.
  • the coupling element is moved by an adjusting element from the engaged in the disengaged position, by motor actuation of the adjusting element by means of a central locking drive.
  • the central locking drive is operated again in the same operating direction the return of the adjustment takes place under spring force to its original position in the manner of a ballpoint pen mechanism and thus the return of the coupling element from the disengaged position in the engaged position.
  • the central venous valve drive has the function of an opening drive, namely actuates the pawl. Between the pawl and the central locking drive can be provided for this purpose, an additional triggering element.
  • the central locking drive has a drivable in two directions drive element in the form of a drive pinion, which meshes with a toothed segment on the adjusting element. In one direction, the drive element actuates the adjusting element, both engaging and disengaging, in the other direction, the trigger element and the closing element.
  • the spring-loaded ballpoint pen mechanism of the known motor vehicle door lock can also be configured with proper coordination of paths and spring forces, that the clutch located in the disengaged position coupling element is actuated by a motor actuation of the adjusting element in one of the engaged position storage position is adjustable with actuated external actuator, from the Clutch element is automatically displaced in the engaged position upon the termination of the operation of the external actuating element, and indeed, as explained, under the action of the spring force of a spring element. This ensures that you can unlock this motor vehicle door lock motor even if at the same time already an opening operation is done from the outside, the external actuating element has been pressed.
  • the engaged position ie the unlocked position, is stored here under spring force and automatically taken by release of the external actuating element under spring force. This is called a "comfort function".
  • the well-known, previously explained motor vehicle door lock is basically designed as an electric lock, namely, it is in normal operation only motor openable. Only in emergency mode it is mechanically openable by manual operation of the external actuating element.
  • the motor vehicle door lock When fitting an electric lock with a "passive entry” function, also called “electronic key", the motor vehicle door lock can be automatically unlocked when approaching the motor vehicle, without a keystroke on a remote control module o. The like.
  • a motor vehicle door locking system with passive entry function requires a certain reaction phase for the control electronics.
  • the duration of the reaction phase is perceived as long compared to conventional motor vehicle door locking systems.
  • the pulling of the outside door handle may in fact already take place if the reaction of the control electronics has not yet been completed.
  • the operator then becomes angry that she has to pull the door handle a second time because she interprets this as a "malfunction".
  • There are therefore various attempts to somehow conceal or shorten the resulting total time of the reaction (DE 195 21 024 A1, DE 197 52 974 A1).
  • a similar problem occurs even if a passive-entry function is not set up, for example, when a passenger tries to open the passenger door from the outside, although there the central locking drive has not yet shifted the coupling element in the engaged position (unlocked position).
  • the teaching is therefore based on the problem, the known, initially explained motor vehicle door lock in such a way that it works mechanically in principle, but nevertheless takes place in each case a fast opening.
  • an opening operation is normally performed mechanically only from the outside door handle. So it is so far a purely mechanical motor vehicle door lock.
  • the central locking drive has received its second function of the opening drive anyway, namely, when the outside door handle has been pulled or pressed faster than the control electronics for controlling the central locking drive and the central locking drive could react itself, which occur especially in the realization of the passive entry function can, regardless of the opening operation of the outside door handle to realize an electric opening.
  • the central locking drive in the second function is effective and actuates the trigger element or the closing element as a motorized opening drive.
  • the electric opening of the motor vehicle door lock is thus only when the operator operated the outside door handle faster than the motor, especially electromotive unlocking mechanism could react.
  • a second operation of the outside door handle is not required because the door opens by itself.
  • the motor vehicle door lock is in one piece, so realized in a unit closing elements and lock mechanism and possibly lock electronics, or in two parts with one part the closing elements in a clamping unit, on the other hand, the lock mechanism and if necessary the lock electronics in one of them spatially separated control unit.
  • the latter is also known from the prior art (DE 44 44 581 A1) with the advantage that the humidity-sensitive control unit in the dry room of a motor vehicle door and only the less moisture sensitive closing unit is arranged with the mechanical closing elements in the wet room of the vehicle door.
  • Typical connecting elements for power transmission here are Bowden cables.
  • the motor vehicle door lock 1 shown schematically in Fig. 1 in a perspective view is shown using the example of a motor vehicle side door lock. Also rear door locks, sliding door locks, flap locks, etc. are covered by the concept of the door lock.
  • Such a motor vehicle door lock 1 is part of a motor vehicle door locking system in which the various motor vehicle locks for motor vehicle doors and motor vehicle doors are motorized, preferably electric motor, unlockable and lockable.
  • the control electronics of such a motor vehicle door closing system can have the passive entry function explained in the general part of the description.
  • the illustrated motor vehicle door lock 1 is tuned in a special way to the boundary conditions in the realization of a passive entry function. As has already been stated in the general part of the description, however, the teaching is also important in a normal remote-controlled motor vehicle door lock 1 with a motor-operated central locking drive.
  • Fig. 1 shows first the motor vehicle door lock 1 with a lock mechanism with a plurality of interacting elements.
  • a hand operated by an outside door handle, force action direction indicated by the arrow 2 from to be actuated external actuating element 3 in the form of a pivotably mounted on a bearing axis 4 external actuating lever.
  • the external actuating element 3 is loaded against the direction of force 2 by a biasing spring, not shown.
  • the external actuating element 3 thus returns under spring force when releasing the outside door handle in its starting position shown in Fig. 1.
  • the coupling element 5 is designed dumbbell-shaped in the illustrated embodiment with a pivot axis 6 and a coupling pin 7. This will be explained in more detail below.
  • a closing element 8 in the form of a pawl.
  • the associated, held by the pawl - closing element 8 - in the closed position lock latch 9 can be seen in Fig. 1 in the closed position. It is, as usual, designed as a rotary latch with a bearing axis 10, without this being limiting.
  • the external actuating element 3 actuates the closing element 8 via the coupling element 5; in the disengaged position of the coupling element 5, the external actuating element 8 executes an idle stroke when the outside door handle is pulled.
  • the disengaged position is shown in FIG. 1.
  • the coupling element 5 is displaceable in the non-actuated external actuating element 3 by a motor-operated adjusting element 11 from the engaged position to the disengaged position and vice versa.
  • a motor-operated adjusting element 11 For the motor actuation of the adjusting element 11 is a central locking drive 12. This has in the illustrated embodiment, indicated in Fig. 1, an electric drive motor 13 and a worm gear 14 on. Other embodiments are known and usable in the prior art.
  • the central locking drive 12 can actuate the closing element 8. How this happens is explained in more detail below.
  • the central locking drive 12 actuates the closing element 8 in the second function only when the external operating element 3 is already in the idle stroke in this phase, that is, has been mechanically actuated so quickly that the coupling element 5 has not yet reached the engaged position.
  • an operator is laminated, that the immediately following opening of the motor vehicle door lock 1 is not done by the mechanical operation with pulling the outside door handle, but was carried out electrically in the second function by the central locking drive 12.
  • This function only occurs in exceptional cases. In the normal case, if sufficient time is available for actuating the adjusting element 11 by the central locking drive 12 in the first function, the subsequent opening operation of the motor vehicle door lock 1 takes place in a classical manner purely mechanically.
  • the central locking drive 12 has a drivable in two directions drive element 15, in particular in the form of a drive pinion or a drive eccentric which actuates the adjusting element 11 in one direction and actuates the trigger element or the closing element 8 in the other, opposite direction.
  • the illustrated and so far preferred embodiment is a different way, namely that the central locking drive 12 has a drivable in two directions drive element 15, in particular in the form of a drive pinion or a drive eccentric, in one direction, the adjusting element 11 in the direction of Wegk-uppelten position and the triggering element or the closing element 8 is actuated and actuated in the other, opposite direction, the adjusting element 11 in the direction of the disengaged position and the closing element 8 releases. It thus has a direction equal operation of the adjusting element 11 in the direction of the engaged position and the closing element 8 in the opening direction (lifting the pawl).
  • the illustrated embodiment shows the drive element 15 in principle designed as a drive pinion, but degenerated into a dental arch, because only a pivoting over a relatively small angular range in both directions is required here.
  • the illustrated embodiment shows, as far as can be clearly seen from a comparison of Fig. 2 and Fig. 3 that here still the "comfort function" explained above is realized.
  • This is achieved in that the coupling element 5 located in the disengaged position is adjustable with actuated external actuating element 3 by a motor actuation of the adjusting element 11 in one of the engaged position storage position (shown in Fig. 3), from which the coupling element 5 in the absence of actuation the external actuating element 3 is automatically displaced into the engaged position (shown in FIG. 2).
  • the latter is preferably done under the force of a biasing spring acting in the illustrated embodiment on the coupling element 5 in the clockwise direction, which is not shown separately here.
  • the storage position which is preceded by the engaged position, is defined in the illustrated embodiment by a lock 3 'on the external actuating element 3, which prevents in befindlichem in idle stroke external actuating element 3, that the coupling element 5 is incident in the engaged position.
  • the coupling pin 7 is under the spring force of the biasing spring, not shown, acting clockwise on the lock 3 '. If the external actuating element 3 has returned to its initial position, the path for the coupling pin 7 is free in the engaged position.
  • a particularly expedient, shown in the drawing construction is characterized in that the Drive element 15 is connected to a pivot arm 16 which pivots on actuation of the drive element 15 in one direction about a pivot axis 17 such that its free end meets the trigger element or the closing element 8 and actuates this, if the coupling element 5 is not in the engaged position, and runs freely, provided that the coupling element 5 is in the engaged position.
  • the coupling pin 7 is not on the coupling element 5 between the pivot arm 16 and closing element 8.
  • the pivot arm 16 can pivot relatively far in a clockwise direction without affecting the pawl - closing element 8.
  • the adjusting element 11 as on the pivot arm 16 at a distance from the pivot axis 17 mounted (pivot axis 11 ') lever is executed, the pivoting of the Swivel arm 16 about the pivot axis 17 performs a substantially linear adjustment movement.
  • the drive movement of the drive element 15 is thus implemented on the one hand in a pivoting movement of the pivot arm 16, on the other hand leads to a displacement of the adjusting element 11 for the purpose of adjustment of the coupling element 5.
  • the central locking drive 12th only runs in one direction (and returns to the starting point against this direction).
  • the coupling element 5 is executed in the illustrated embodiment as pivotally mounted on the adjusting element 11, one end running in a slot 18 with the coupling pin 7 lever.
  • the gate 18 is formed in the adjusting element 11 arcuate (bean-like), right next to this gate 18 is the pivot axis 6 of the coupling element fifth
  • the coupling element 5 forming the lever is spring-loaded to the engaged position of the facing end of the link 18 back, by a biasing spring, not shown here.
  • FIG. 1 to 3 also make it clear that in the illustrated and insofar preferred embodiment, an actuating arm 19 of the closing element 8 and an actuating arm 20 of the external actuating element 3 form an open slot 21, in which the coupling pin 7 of the coupling element 5 is immersed in the engaged position and not immersed in disengaged position.
  • the engaged position is shown in FIG. 2, the disengaged position is shown in FIG. 1.
  • the second function for the central locking drive 12 is thereby realized that the actuating arm 19 of the closing element 8 extends beyond the open end of the slot 21 and the pin 7 of the coupling element 5 in disengaged position or possibly in the storage position in front of this actuating arm 19th stands. Even then, the power transmission to the closing element 8 - pawl - done, but only from the pivot arm 16 of the central locking drive 12. In contrast, the coupling pin 7 deviates during normal operation by hand upwards into the slot 21, the pivot arm 16 is now ineffective, but the external actuating element 3 acts via the actuating arm 20.
  • the part immersed in the slot 21 need not be a pin 7.
  • This part 7 of the coupling element 5 may also have many other forms, for example, be integrally formed on the coupling element 5.
  • Fig. 3 shows the central locking drive 12 below the closing element 8 and the rotary latch 9.
  • this arrangement builds relatively high overall.
  • the external actuating element 3 is mounted on the bearing axis 4, on which the closing element 8 is mounted.
  • Fig. 4 shows an embodiment, which initially differs from the previously described embodiment in that the central locking drive 12 has been moved upwards, approximately to the height of the closing element 8. This makes the overall structure of the motor vehicle door lock 1 at least in height (relative to the drawing plane) more compact.
  • the existing in the first embodiment adjustment element 11 is omitted.
  • the coupling element 5 is mounted directly on the drive element 15.
  • the coupling element 5 itself is limited relative to the drive member 15 relative movable, in that it is designed as running on the drive element 15 in a link 18 lever which is spring-loaded to the engaged position of the facing end of the link 18 in the drive element 15 out.
  • Fig. 4 shows the Fig. 1 corresponding position in this embodiment, ie the locking position, the coupling element 5 so in the disengaged position.
  • the lock 3 on the outer actuating element 3 would in this position in the idle stroke on the coupling pin 7 of the coupling element 5 significantlyschwenken, this coupling pin 7 would stop before the actuating arm 19 of the closing element 8.
  • the indicated pivot arm 16, however, would meet in this position even with persistent coupling element 5 (deflected against spring force) on the pin 7 and move over this the actuating arm 19.
  • Fig. 5 shows the lower portion of the external actuating element 3 with the lock 3 'in a fragmentary side view. It can be seen that the external actuating element 3 'to the formation of the lock 3' is "cranked" and protrudes with the lock 3 'in the movement path of the coupling pin 7. In the position shown in Fig. 4, as shown in FIG. 5, the lock 3 'relative to the coupling pin 7 offset downward, the coupling pin 7 is not hit. However, if the coupling pin 7 laid down, so he enters the lock 3 'and this can then cause the transmission of force to the actuating arm 19 of the closing element 8 with the interposition of the coupling pin 7.
  • FIGs 6 and 7 show an embodiment in which the motor vehicle door lock is made in two parts.
  • This concept is already known from the prior art (DE 44 44 581 A1) and allows to accommodate the moisture-sensitive components of the motor vehicle door lock in the drying room of a motor vehicle door and to leave only the less moisture-sensitive closing elements in the wet room.

  • This power transmission means 24 is already preferred in the prior art, a Bowden cable. This is also the case in the illustrated embodiment. Thus, the laying of the mechanical power transmission means 24 from the drying room in the wet room is best carried out. In principle, of course, other power transmission means 24, for example rods with or without lever can be used.

  • Fig. 6 still has a Bowden cable 26 for attacking a lock cylinder on Adjusting element 11 (ZV-safety lever) and a second electric drive motor 27 and a separate worm wheel 28 having theft-securing drive. This shifts an anti-theft pin 29 in an angular slot of an internal operating lever 30, which in turn is connected by means of another Bowden cable 31 to a door inside handle.
