Definitions

  • the invention relates to a motor vehicle door lock, with a locking mechanism, an actuating lever chain and a drive for electrically opening the locking mechanism, wherein an additional drive is provided, which, if necessary, "locked” the actuating lever chain in its position in which the actuating lever chain is mechanically interrupted.
  • a motor vehicle door lock of the structure described above is in the utility model DE 20 2010 013 611 U1 described.
  • the overall aim here is to reduce the structural design with an identical range of functions, that is to say to realize an additional safety function through a coupling in the drive train between a so-called OBW drive (Open By Wire) and a pawl.
  • OBW drive Open By Wire
  • the procedure in the known motor vehicle door lock is that a switchable coupling between an actuating lever and a release lever of a lock mechanism is provided.
  • the clutch can be "unlocked” into a first clutch state and brought into a second clutch state "locked”.
  • the electrical opening of a locking mechanism with the aid of the electric drive is regularly accomplished so that an operator, for example, an outside door handle or a door inner handle acted upon. This regularly results in a switch operation, which is interpreted as an opening request. As a result, an opening signal is generated which causes the electric drive to be energized to electrically open the locking mechanism.
  • blocking elements are used in practice, for example. The blocking element in question ensures a mechanical securing of the electric drive.
  • the electric drive can electrically open the locking mechanism.
  • the release of the blocking element is regularly coupled to a mechanical loading by means of the outside door handle or the inside door handle. That is, the outside door handle or the inside door handle is mechanically connected to the blocking element and ensures that the blocking element releases the electric drive, so that it can work in the opening sense on the locking mechanism. This has proven itself in principle.
  • the invention is based on the technical problem of further developing such a motor vehicle door lock so that a solution is made available which, in principle, also enables a remote control, wherein in addition, a mechanical opening of the locking mechanism should succeed in emergency opening operation.
  • a generic motor vehicle door lock in the invention is characterized in that the operating lever chain consistently "locked” maintains its position and only when the position "locked” the operating lever chain is reached, generates an opening signal for the drive to electrically open the locking mechanism is, with only in the event of an emergency opening or in the event of a crash the operating lever chain is effective and previously "unlocked” transferred to their position in which the locking mechanism can be opened mechanically via the operating lever chain so that, for example, rescue personnel can open an associated vehicle door.
  • the motor vehicle door lock according to the invention has the previously described "temporary crash redundancy” (TCR).
  • TCR temporary crash redundancy
  • the electrical opening of the locking mechanism with the aid of the drive can always and only then take place when a corresponding opening signal is generated. That is, the locking and the electrical opening are linked together in such a way that no mechanical locking is possible without opening.
  • the opening signal is coupled to that before the operating lever chain assumes its position "locked” or is transferred to this position.
  • the additional drive does not mechanically act on the operating lever chain, if this has already taken their position "locked”. That is, the additional drive transfers the actuating lever chain "locked” into its position as needed.
  • the operating lever chain consistently maintains its "locked” position. In this way, an unlocking is realized, which ensures that the operating lever chain is kept in the "locked” position.
  • any mechanical loading of the actuating lever chain can not be implemented in an opening of the locking mechanism.
  • the electric drive for electrically opening the Gesperres not ensure this, because the opening signal is missing. So there is maximum security.
  • the invention opens up the possibility of fernzubedienen the drive for electrically opening the Gesperres. Because this is ultimately applied to the additional drive, which, if necessary, "transferred” locked the actuating lever chain in its position. At the same time, the admission of the additional drive ensures that the necessary opening signal is generated, so that the drive for electrically opening the locking mechanism can even run. The opening signal is of course only generated when the operating lever chain has reached its "locked” position.
  • the additional drive is designed so that its application in the direction "locked” the actuating lever chain at the end of the travel also generates the respective opening signal.
  • a motor vehicle door lock is shown, which is equipped with a not explicitly shown ratchet of substantially rotary latch and pawl.
  • the motor vehicle door lock has a release lever 1.
  • the release lever 1 is rotatably mounted together with a blocking element or blocking lever 2 about a common axis 3 in a lock housing 4.
  • a drive 4, 5 is provided, which serves for the electrical opening of the locking mechanism.
  • the drive 4, 5 is composed of an electric motor 4 and a driven pulley 5, which can perform rotary movements initiated by the electric motor 4 in the clockwise direction and in the counterclockwise direction about its axis 6.
  • a movement of the driven pulley 5 in the counterclockwise direction about its axis 6 ensures that a provided in plan view of the back contour with the release lever 1 interacts such that the release lever 1 is pivoted about its axis 3 in a clockwise direction (see. Fig. 1 ).
  • the locking mechanism is opened, in which the release lever 1, the pawl of the locking mechanism pivots away from the associated rotary latch and opens the rotary latch spring-assisted.
  • a lock pin previously caught by the catch comes free.
  • the clockwise movement of the driven pulley 5, however, corresponds to the emergency opening and at the same time that the locking mechanism can be opened mechanically.
  • an additional drive 7, 8 used according to the invention which is comparable to the drive 4, 5 is constructed.
  • the additional drive 7, 8 is also composed of an electric motor 7 and a driven pulley 8.
  • the electric motor 7 is equipped on its output shaft with a worm which meshes with an outer peripheral toothing of the driven pulley 8 to pivot the driven pulley 8 about its axis in a clockwise or counterclockwise direction.
  • the additional drive 7, 8 in the exemplary embodiment is a safety drive.
  • the backup drive may act as a child safety drive and / or anti-theft drive.
  • the additional drive 7, 8 or backup drive is a child safety drive.
  • the locking lever 10 is consistently “locked” in its position, because insofar an unlocking lock is realized, as will be explained in more detail below. Only when the so-called emergency opening operation is carried out, the locking lever 10 is typically transferred to its "unlocked” position, so that in this (rare) case, an actuating lever or operating lever chain 12 is effective and can mechanically open the locking mechanism. As already explained above, the emergency opening corresponds to a clockwise movement of the driven pulley 5.
  • the operating lever mechanism 12 has in addition to a lever 12 in addition to a clutch lever, which interacts depending on its position with the release lever 1 or not for further basic structure.
  • the actuating lever or connecting lever 12 and the clutch lever are then mechanically connected via an intermediate lever with the release lever 1, depending on the position of the clutch lever.
  • the operating lever chain 12 is “locked” in its position, the operating lever chain 12 is mechanically interrupted and is not lying continuous mechanical connection, for example, from an outside door handle or inside door handle up to the release lever 1 before.
  • the position "unlocked” the actuating lever chain 12 corresponds to the fact that the release lever 1 can be acted upon by the actuating lever chain 12 mechanically to open the locking mechanism. This is only the case in the embodiment and only possible if a so-called emergency opening is to take place or should take place.
  • the additional drive 7, 8 or child safety drive is mechanically connected to the adjusting lever 12.
  • the adjusting lever 12 is pivotally connected to the driven pulley 8 of the additional drive 7, 8.
  • the relevant additional drive 7, 8 operates on the coupling lever of the actuating lever mechanism 12.
  • the adjusting lever 12 has in detail a locking pin 11 which engages in an associated recess on the locking lever 10. In this way, the adjusting lever 12 can pivot the locking lever 10, for example, in the positions "locked” or “unlocked” convict and thereby implement the parental control function.
  • the additional drive 7, 8 acts on a sensor when the actuating lever mechanism 12 is in the "locked" position.
  • This sensor may be a child safety sensor or child safety switch. Only when the sensor in question is acted upon, the initially mentioned opening signal is generated, which causes the drive 4, 5 is energized to electrically open the locking mechanism. That is, the electric opening operation of the locking requires that a signal from the sensor from a not registered control unit is registered, to which the sensor is connected.
  • the application of the sensor presupposes that the additional drive 7, 8 from its position “off or child safety off” as shown in the Fig. 1 at the transition to Fig. 2 finally the position after the Fig. 3 reached, which corresponds to the position "on or parental lock on”. Only when the additional drive 7, 8 this position after Fig. 3 has reached, the sensor undergoes a corresponding action and the drive 4, 5 electrically open the locking mechanism.
  • the invention ensures that, on the one hand, the locking lever 10 definitively assumes or retains its "locked” position because the counterclockwise movement of the driven pulley 8 of the additional drive 7 connected to the transition from the "off" position to the “on” position, 8 corresponds to the fact that the locking lever 10 is pivoted about its axis, if necessary, in a clockwise direction, as in the transition from the Fig. 1 to Fig. 2 becomes clear.
  • the additional drive 7, 8 the operating lever chain 12 is transferred to its "locked” position, in which there is no continuous mechanical connection to the triggering lever 1. Any mechanical loading of the actuating lever chain 12 can therefore not lead to an unwanted opening of the locking mechanism.
  • the signal generated by the sensor in this way is now interpreted as an opening signal and ensures that the drive 4, 5 electrically opens the locking mechanism.
