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, and with a rotary electric motor drive for the locking mechanism, the electric motor drive being a rotatable and actuable in at least one direction of movement and an opposite direction of movement Has drive element, and with the aid of the drive element at least a first securing position and a second securing position can be controlled.
  • the motor vehicle lock is in particular a motor vehicle door lock.
  • the term motor vehicle lock also includes motor vehicle bonnet locks, motor vehicle tailgate locks, motor vehicle tank flap locks, motor vehicle seat locks, etc.
  • motor vehicle door locks and in particular motor vehicle side door locks the control of different functional states and in particular different locking positions is of particular importance. These locking positions usually correspond to different security positions, for example “locked/unlocked”, “anti-theft/anti-theft” and “child-proof/child-unlocked”.
  • an actuating device for a motor vehicle lock has already been described, which has a multifunction clutch lever.
  • An opening movement of the multifunction clutch lever corresponds to the opening of the locking mechanism. This opening movement can be prevented altogether by an associated anti-theft device, a central locking device and a child safety device.
  • an electric drive for the central locking lever as well as one independent of it and additional intended electric drive provided for the anti-theft lever.
  • 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, taking into account a compact and cost-effective design, the design effort is reduced again compared to previous procedures.
  • the rotary electric motor drive with its rotatable drive element that can be acted upon in the direction of movement and in the opposite direction of movement ensures that the first safety position, the second safety position and then at least one further third safety position can be controlled.
  • the first securing position is a locked position or central locking position.
  • the second security position belongs to the anti-theft position, whereas the third security position corresponds to the child-proof functional position.
  • the (single) drive element in connection with the (single) rotary electric motor drive is also set up within the scope of the invention in that all three safety positions can not only be assumed or controlled, but also - independently of one another - can be used again .
  • the mentioned and at least three securing positions can be controlled in the direction of movement, in the opposite direction of movement or in both directions of movement of the drive element and, if necessary, can be laid out.
  • all essential securing positions can be engaged and disengaged again with the aid of the (single) rotary electric motor drive.
  • the electromotive drive is therefore able to represent and approach the functional positions "locked/unlocked” or "centrally locked/centrally unlocked” as well as “theft-proof/anti-theft” and finally "child-proof/ child unlocked”. All of this is achieved by taking into account a compact and cost-optimized structure, which has so far remained unparalleled in the state of the art.
  • the locking lever has a total of two control arms, one control arm interacting with the unlocking arm as part of the first blocking lever, whereas the second control arm interacts with the locking arm as a further part of the first blocking lever.
  • the drive element is also advantageously set up to control the second security position with an anti-theft lever and at least one second blocking lever.
  • the drive element interacts with the anti-theft locking lever in question and the at least one second locking position to control the second locking position blocking lever.
  • the second blocking lever in question is typically elastically coupled to the anti-theft lever.
  • an actuation of the anti-theft lever means that the blocking lever can be taken along via the elastic coupling, as will be explained in more detail below with reference to the description of the figures.
  • the selective engagement and disengagement of the anti-theft lever and consequently the anti-theft function means that the functional position in question can be approached independently of other functional positions. For example, it is not necessary to assume the locking position beforehand.
  • the design is then such that the anti-theft lever is usually articulated to at least one anti-theft lever.
  • the anti-theft locking lever can be selectively actuated via the anti-theft locking lever. At this point, it is usually possible to selectively disengage or also selectively engage the anti-theft locking lever.
  • the anti-theft locking lever is in turn designed in two parts, which is also explained in more detail below with reference to the description of the figures.
  • the individual security positions usually correspond to different operating levels. As a result, the securing positions can be approached and laid out again independently of one another. Together with the two directions of movement, there are sufficient degrees of freedom to ensure functionally reliable operation.
  • the drive element is advantageously designed as a drive pulley.
  • the drive pulley generally has at least one control contour for interacting with the locking lever, the anti-theft lever and the child safety lever. This means that with the help of this one (single) control contour on the drive pulley, the locking lever, the anti-theft lever and the child safety lever can be inserted, for example. Sometimes it is also possible to lay out the lever in question with the help of the control contour or another additional control contour. All of this is achieved by taking into account a compact, cost-effective and functionally reliable structure. This is where the main advantages can be seen.
  • a motor vehicle lock which has a not expressly shown locking mechanism consisting essentially of a rotary latch and a pawl.
  • a rotating (single) electric motor drive 1 is implemented for the locking mechanism, which, according to the exemplary embodiment, is reduced to a rotatable drive element 1 that can be acted upon in at least one direction of movement and an opposite direction of movement.
  • the rotatable drive element 1 is a drive disk which can be acted upon about an axis 2 in one direction of movement (counterclockwise) and in an opposite direction of movement (clockwise).
  • first safety position or locking position With the help of the drive element or the drive pulley 1, a first safety position or locking position, a second safety position or anti-theft position and finally a further third safety position or child safety position can now be approached.
  • the first securing position or locked position is in the 4 shown.
  • the second security position or anti-theft position is the subject of 8 .
  • the child safety position on the other hand, is in the 13 played back.
  • the positions in question can of course also be interpreted again, as will be explained in detail below.
  • the securing positions in question can be controlled both in the direction of movement, in the opposite direction of movement or in both directions of movement of the drive element or the drive pulley 1 .
  • the drive element 1 interacts with a locking lever 5 and at least one first blocking lever 6, 7 to control the first securing position or locking position.
  • a locking lever 5 and at least one first blocking lever 6, 7 to control the first securing position or locking position.
  • the two arms 6 , 7 are mounted coaxially on a common axis 8 .
  • a spring is provided which the two arms 6, 7 in their in the 1 exemplified mostly right-angled alignment biases each other.
  • two control arms 9, 10, which are connected to the locking lever 5, are also relevant in this context.
  • the control arm 9 ensures that the unlocking arm 6 is acted upon, whereas the control arm 10 is responsible for the actuation of the locking arm 7 as part of the first blocking lever 6 , 7 .
  • an anti-theft lever 11 is realized.
  • the drive element or the drive disk 1 interacts with the anti-theft lever 11 and at least the second blocking lever 12 to control the second safety position or anti-theft position.
  • the second blocking lever 12 is elastically coupled to the anti-theft lever 11, with a spring 13 being interposed at this point .
  • a comparison of the Figures 5 to 8 that the anti-theft lever 11 is articulated to at least one anti-theft lever 14, 15 is coupled.
  • the anti-theft lever 15 is mounted on the anti-theft lever 14 .
  • the anti-theft locking lever 14 in turn engages in a joint mount 16 on the anti-theft locking lever 11 which ensures the articulated coupling of the anti-theft locking lever 11 to the two anti-theft locking levers 14 , 15 .
  • the drive element or the drive pulley 1 interacts to control the third safety position with a child safety lever 17, which can be used in particular in the figures 13 and 14 can recognize.
  • the child safety lever 17 is rotatably mounted with respect to an axis 18 in a lock housing, not shown, in which the drive pulley 1 and the anti-theft lever 11 and also the other levers 12, 14, 15 are stored.
  • a spring (not shown) ensures that the child safety lever 17 is prestressed in the direction of its deployed position, as will be explained in more detail below.
  • control contour 19 on the drive pulley 1.
  • control contour 20 is provided, which is referred to below in the description of the mode of operation.
  • Two contours 21 which each extend radially on both sides of the control contour 19 are then of further importance.
  • the motor vehicle lock can now be “locked” in the first securing position or the functional state, as it is ultimately in the 4 is reproduced below.
  • the electromotive Drive 1 or the drive pulley 1 in the direction of movement, that is, moved counterclockwise. You can see that in the transition from 1 about the 2 to the 3 .
  • the control contour 19 moves against the locking lever 5. That has the transition from the 1 to the 2 and up to 3 result in the locking lever 5 being pivoted clockwise about its axis 8 .
  • the locking lever 5 with its control arm 9 ensures that the unlocking arm 6 as part of the first blocking lever 6, 7 follows the clockwise movement.
  • the unlocking arm 6 is pivoted to overlap with the drive pulley 1 .
  • the drive pulley 1 When transitioning from 3 to the 4 the drive pulley 1 is reset after its previous blockage in the opposite direction of movement, ie clockwise. This is ensured by a spring acting on the drive pulley 1, which is or can be a center-zero spring. In this process of return of the drive pulley 1 in the basic position comparable to the 1 the left contour 21 moves away from the locking arm 7 as part of the blocking lever 6, 7 compared to the control contour 19. Accordingly, the locking arm 7 pivots during the transition from the 3 to the 4 up, so that subsequently the control contour 19 does not (anymore) drive against the locking arm 7, but rather is free of it.
  • the anti-theft locking lever 11 ensures, via the articulated connection or the joint mount 16 , that the anti-theft locking lever 14 , 15 is activated, namely essentially rotates counterclockwise about its axis 23 .
  • the movement of the locking lever 11 clockwise about its axis 22 as a result of being acted upon by the control contour 19 has the further effect that the second blocking lever 12 or the spring 13 between the anti-theft lever 11 and the second blocking lever 12 is tensioned.
  • the blocking lever 12 rests against the drive pulley 1 as a whole.
  • the anti-theft device is now interpreted selectively, ie only the anti-theft device lever 11 in such a way that the drive pulley 1 is acted upon in the direction of movement, so that the control contour 19 can act on the anti-theft device lever 14, 15.
  • the contour 21 ensures that the second blocking lever 12 is held in the collapsed position. That's in the 9 shown.
  • the anti-theft lever 11 is now completely disengaged via the anti-theft locking lever 14, 15, specifically selectively, that is, considered in isolation. That's in the 10 shown.
  • control contour 19 first moves against the second blocking lever 12 .
  • the electric motor 4 is switched off and the control contour 19 or the worm wheel 11 can move back into its basic position in the opposite direction of movement. Now the basic position is again “locked” and shown with the anti-theft device designed, as already the subject of 4 was.
  • the contour 21 holds the unlocking arm 6 firmly. This allows the transition from the 11 to the 12 follow the locking arm 7 and swing in.
  • the locking lever 5 is completely pivoted out about its axis 8 in this position and is in its functional position “unlocked”.
  • the control contour 19 moves against the unlocking arm 6 so that the end position is reached as a result. Subsequently, the drive pulley 1 reverses counterclockwise and the blocking lever 6, 7 swings out. Now the basic position "unlocked” is reached, as already related to 1 has been illustrated and described.
