Definitions

  • the invention relates to a motor vehicle door lock, with a locking mechanism consisting essentially of a catch and a pawl, further comprising at least one opening lever for the Pawl, and with a preferably rotational working drive for the opening lever.
  • Such a motor vehicle door lock becomes exemplary described in the context of DE 196 50 826 A1. It works the rotary drive on a lever arm of the opening lever or release lever, while the other lever arm of the Opening lever or release lever of a quick release spring is charged. The interpretation is such that the release lever under the influence of the quick release spring in the Aushebewolf for the pawl is movable and the pawl entrains accordingly when the output cam performs a rotational movement.
  • Comparable motor vehicle door locks are in the Used in practice, mostly in connection with a tailgate or rear door lock. It is important after an electrically initiated opening request the relevant Unlock vehicle door lock or electrically open to the flap, door or the like then be able to open manually (completely). The described electric opening process thus ensures for the ratchet to be fully opened, so that an additional opening stroke - for example, by an internal operating lever - can be omitted. - Yet Of course, such embodiments of the this application.
  • the invention is based on the technical problem, a such motor vehicle door closure so on, that eliminates disturbing noise with a simple structure.
  • the invention proposes in a generic motor vehicle door lock before that the catch during closing the drive from Opening lever uncoupled, so that the pawl unhindered can come up.
  • the opening lever with a receptacle for an actuating pin of the drive equipped.
  • This actuating pin is usually of a driven pulley, which is a motor, in particular a reversing electric motor, in both directions of rotation rotatively drives.
  • the engine has mostly via an output shaft and a worm wheel, which meshes with the respective driven pulley.
  • the drive thus consists of the aforementioned components Engine, output shaft with worm wheel, driven pulley and Actuating pin together.
  • the opening lever usually with a Locking pin and the rotary latch with an actuating contour equipped
  • the opening lever can be indirectly or uncouple directly from the drive, namely by a corresponding interaction of this lock pin on the opening lever and the operating contour on the rotary latch.
  • the Uncoupling from the drive has the consequence that any Rotations of the drive the opening lever (and thus the Do not touch the pawl). So it does not matter if the drive continues to rotate after this separation, one certain position etc ..
  • the opening lever has mostly a stop surface, which the opening lever and thus the pawl positioned in the closed position of the locking mechanism.
  • the stop surface usually attacks an axis of the drive.
  • the opening lever has mostly via a positioning surface or Guide contour, which the opening lever against the drive aligned so that the upright on the driven pulley Actuating pin to open the locking mechanism in the course a rotation of the drive reaches the recording safely.
  • the positioning surface provides the opening lever for that the actuating pin of the drive properly engages in the receptacle on the opening lever and in this occurs when the drive is correspondingly rotary is moved. Only then can it be guaranteed that the further rotating actuating pin properly the recording is and as a result entrains the opening lever.
  • the opening lever is still with a slot guide equipped, in which a guide pin the pawl engages.
  • This slot guide provides that the pawl on the one hand in the course of electric Opening procedure is issued, because insofar the Guide pin rests against one end of the slot guide.
  • the opening lever has a boundary surface, which drive with the pawl open Stops on a counter surface blocked.
  • This counter surface like as a fold of an already existing lock housing be educated.
  • the invention at least suggests an ejector lever in front, which in the core for it Ensures that the drive runs smoothly through a pre-block ride is stopped. This makes the drive easy and cost-effective, because additional switches to Position inquiry, special measures to control the Motors etc. can be omitted.
  • the ejector lever between the catch and Opening lever interposed and separates the opening lever during the closing process of the catch from the drive.
  • the ejector lever is generally used as a lever arm formed, with its fulcrum opposite an actuating surface for the locking pin on Opening lever is provided.
  • the Ejector lever via an ejector pin, which of the Actuation contour on the rotary latch in the course of its closing movement is engaged behind. This ensures that that the catch entrains the ejector lever and this in turn the opening lever through the interaction of actuating surface and locking pin from the drive separates.
  • a motor vehicle door lock which in strikingly simple construction a reliable Ensures function in the sense of electrical opening, in particular so-called "sham closing" and disturbing noises are avoided.
  • a motor vehicle door lock is shown, who as usual has a locking mechanism 1, 2, the essentially composed of rotary latch 1 and pawl 2 is.
  • a locking mechanism 1, 2 the essentially composed of rotary latch 1 and pawl 2 is.
  • an opening lever. 3 for the pawl 2 and is finally a rotatory working drive 4, 5, 6, 7 realized for the opening lever 3.
  • the drive 4, 5, 6, 7 consists of a reversing Electric motor 4, a connected output shaft with Worm wheel 5, a driven pulley 6 and finally an actuating pin 7 on the driven pulley 6 together.
  • the electric motor 4 is basically capable of perform reversing movements, so that the driven pulley Turn 6 clockwise and counterclockwise can, as indicated in Fig. 1 by a double arrow is. In the context of the embodiment, however, only one direction of rotation (counterclockwise rotation) used.
  • the Actuating pin 7 on the driven pulley 6 is a Recording 8 assigned to the opening lever 3.
  • the opening lever 3 still has a locking pin. 9 and a slot guide 10, in which a guide pin 11 engages the pawl 2.
  • Boundary surface 12 is provided on the opening lever 3, which with open pawl (see Fig. 4) the drive 4, 5, 6, 7 by striking on an only indicated counter surface 13 blocked. This counter surface 13 is present part an unspecified drawn lock housing.
  • an ejector 14th realized, which between the catch 1 and opening lever 3 is interposed.
  • This ejector lever 14 is in Frame of the embodiment designed as Einarmhebel and pivots about a pivot point 15.
  • the fulcrum 15th opposite is an actuating surface 16, which cooperates with the locking pin 9 on the opening lever 3.
  • the ejector lever 14 is a center-zero spring 17, which ensures that the ejector lever 14, although pivoting movements upwards (see FIG. 3) and below (see Fig. 5) can perform, but always restoring forces of the center zero spring 17 constructed be, which the ejector lever 14 in its original Return position corresponding to FIGS. 1, 2, 4 and 6.
  • the rotary latch 2 is equipped with an actuating contour 18, which interact with an ejector pin 19 enters the ejector 14, as follows will be described in more detail. It can be seen that the catch 1 both a main and a pre-locking position is able, but not mandatory and for the present invention is also immaterial.
  • Fig. 1 is the Basic position of the motor vehicle door lock with locked Lock 1, 2 or in the main catch located catch 1 shown.
  • the driven pulley 6 is in Counterclockwise moves, as indicated in Fig. 2 is.
  • the driven pulley. 6 projecting actuating pin 7 of this counterclockwise movement.
  • the Opening lever 3 initially also a counterclockwise movement around the guide pin acting as an axis of rotation 11 on the pawl 2. This can be attributed to that the actuating pin 7 on a guide contour 20 of the opening lever 3 slides along, which below a forward projecting approach with a Stop surface 21 is arranged.
  • This stop surface 21 on the opening lever 3 ensures that the opening lever 3 during this process opposite an axis A of the drive 4, 5, 6, 7 is positioned, because the stop surface 21 so far on the associated Axis A is present (see the transition from Fig. 1 to Fig. 2).
  • Opening lever 3 ensures that this is a minor Turn clockwise around the axis of rotation or Guide pin 11 has performed, after the described counterclockwise movement.
  • the actuating pin 7 in the position in the recording 8 of the opening lever 3 to be able to intervene (see. Fig. 2). This leads to a further rotation of the driven pulley 6 and thus the actuating pin 7 in the counterclockwise direction cause the opening lever 3 in the direction of the counter surface 13 is moved, which indicates an arrow in Fig. 3.
  • the pawl 2 opening thereby provides for the catch 1 to rotate about its axis 23 in a clockwise direction pivoted and the ejector 14 in this case after moved above, because insofar the actuation contour 18 at the Rotary catch 1 the ejector pin 19 on the ejector 14th acted upon accordingly.
  • the catch is complete opened (see Fig. 4), so that an associated Tailgate, rear door or the like with only hinted Locking pin 24 dug or opened in the direction of the arrow can be.
  • the actuating contour engages behind 18 on the catch 1, the ejector pin 19 on the ejector 14, so that the rotary latch 1 in its counterclockwise movement the ejector lever 14 entrains and this in turn the opening lever 3 from the drive 4, 5, 6, 7 separates. Because the counterclockwise movement of the catch 1 and the interaction of their actuating contour 18 with the ejector pin 19 of the ejector lever 14 has to As a result, the ejector lever 14 is also counterclockwise around its axis 15 performs (see Fig. 5). Due to this counterclockwise movement, the actuating surface decreases 16 of the ejector lever 14, the locking pin.
