Definitions

  • the invention relates to a motor vehicle door lock, with a locking mechanism, also with an opening drive operating on the locking mechanism and an actuating lever mechanism, further with at least one sensor for requesting an operator opening request, and with a securing device which prevents at least in its "secured” position an opening of the locking mechanism ,
  • the opening drive in such motor vehicle door locks generally provides for the so-called electrical opening of the locking mechanism.
  • a handle for example an external operating lever and / or an internal actuating lever
  • the acted upon by an operator sensor after a corresponding operator opening request ensures that the opening drive or electric drive is energized to the opening of the locking mechanism.
  • the locking mechanism is opened according to the motor - not manually. This usually happens in such a way that the opening drive pivots a release lever, which in turn lifts a pawl of a catch as respective components of the locking mechanism.
  • a typical example of a motor vehicle door lock or a motor vehicle door lock with the described functionality for electrically opening is in the EP 1 320 652 B1 presented and described.
  • the electric drive acts in normal operation, the locking mechanism for electrical opening and ensures at least in emergency operation for a mechanical opening of the locking mechanism.
  • the emergency operation typically corresponds to an emergency opening, which is or may be required if, for example due to a voltage drop in the motor vehicle, the electric drive is no longer reliable or no longer works. Then, in the context of the known teaching and in the course of emergency operation, nevertheless, a mechanical opening of the locking mechanism is possible, the emergency opening.
  • a generic motor vehicle door lock is in the context of DE 197 06 393 B4 described.
  • various control electronics and associated signal generator realized.
  • the position of a child safety device is also queried as a safety device with the help of a child safety switch. If the child safety device is inserted, the operation of the center-zero switch or sensor on the inside door handle does not lead to an opening signal and consequently not to the fact that the applied sensor correspondingly controls the opening drive. This has proven itself in principle.
  • the document DE 20 2011 002154 U1 discloses another motor vehicle lock assembly according to the term of claim 1 for a motorized lifting a pawl, wherein a sensor is provided, through which in normal operation upon actuation of an actuating element, the motorized lifting of the pawl is triggered.
  • an opening drive is provided consisting of a drive motor with downstream screw, wherein the screw is coupled via a toothed segment with an opening lever. If the actuating element is now actuated, the opening lever engages with the sensor. The actuation of the sensor in turn leads to a control of the drive motor, so that the toothed segment rotates the pawl lift.
  • the document DE 10 2004 036 670 A1 discloses a motor vehicle door lock with a ratchet, an opening drive for the ratchet, an inner handle, an outer handle and two sensors, each of which is associated with one of the inner handle and one of the outer handle.
  • the opening drive is actuated by acting on the sensor assigned to the external handle.
  • a fuse unit is provided which prevents an opening of the locking mechanism in the "secured" position.
  • an intermediate lever is provided which, in accordance with the position of the securing unit, couples the inner handle with the sensor assigned to the outer handle.
  • the generic teaching after the DE 197 06 393 B4 is characterized by a complex functionality and therefore has the various Sensors on the one hand to query the safety device and on the other hand the handle (inner handle and outer handle). This results in a large number of necessary components for the realization of the known motor vehicle door lock.
  • the various sensors must be connected to one or more control units to evaluate their signals and control the opening drive. This is typically done today with the help of so-called component carriers including associated interconnect structure.
  • This strip structure is often designed as a stamped grid and expensive to manufacture and assemble for the described reasons in the known teaching.
  • the complex functionality in the teaching of the starting point according to the DE 197 06 393 B4 not only leads to a large number of sensors, but also to the fact that complex strip conductors are required in order to couple the sensors with an associated control unit or with each other and actually be able to mechanically map all the desired functional states.
  • relatively high production costs are observed. These can be at least partially justified by the described comfort gain, for example in conjunction with the "passive entry” function.
  • the cost pressure in the automotive industry is enormous, so cheaper solutions are required. This is where the invention starts.
  • the invention is based on the technical problem of further developing a motor vehicle door lock of the construction described at the outset such that the technological and design effort is reduced and, in particular, reduced manufacturing costs are observed compared to the prior art.
  • a generic motor vehicle door lock in the invention is characterized in that the operator opening request mechanically converting intermediate lever of the operating lever mechanism in accordance with the position of the securing device with an actuating lug the sensor driving the opening drive selectively applied or not acted upon.
  • a special intermediate lever is used as part of the actuating lever mechanism.
  • This intermediate lever mechanically implements the operator opening request.
  • said intermediate lever for example, by means of a handle (inner handle and / or external handle) is pivoted at the opening.
  • this operator opening request is mechanically implemented by a mechanical coupling of the intermediate lever to the handle.
  • the intermediate lever typically performs a pivotal movement about an axis, with the aid of which it is mounted in a housing, a lock case, etc.
  • the pivoting movement of the intermediate lever corresponds to the sensor actuating the opening drive being acted upon by the actuating nose.
  • the sensor action in turn causes the working on the locking opening drive is driven.
  • a release lever is pivoted, for example, by means of the opening drive, which in turn lifts a pawl from a catch.
  • the ratchet is typically composed of the catch and the pawl, wherein the pawl has fallen into the catch in the closed state of the locking mechanism.
  • the safety device with its respectively assumed position (“unsecured” or “secured”) ensures that the operator opening request opens into a pivoting of the intermediate lever (namely “unlocked” in the position of the safety device). ) or not (when the safety device assumes its position “secured”). In this way, the invention comes out with regularly a single sensor.
  • the position of the safety device is not within the scope of the invention - as in the prior art according to the DE 197 06 393 B4 - interrogated by an additional sensor.
  • the sensor which ultimately detects the operator opening request and is acted on by the intermediate lever is the only sensor in the scope of the invention. Because the position of the safety device has a direct influence on whether the intermediate lever acts on the sensor or not.
  • a further advantage is that the intermediate opening lever which mechanically converts the opening of the operator's opening can be mechanically connected both to the inner handle and to the outer handle or both. That is, within the scope of the invention also separate sensors for one hand, the inner handle and on the other hand omitted External handle, as in the aforementioned and generic state of the art according to the DE 197 06 393 B4 be used. Furthermore, the construction is simplified insofar as the intermediate lever may alternatively or in addition to the respective handle also experience a motorized action to open the locking mechanism. This is conceivable, for example, in connection with a remote control of the motor vehicle door lock or the already mentioned "passive entry" access.
  • the motor vehicle door lock according to the invention is structurally particularly simple. Because ultimately sufficient for the realization of the function "electrical opening" taking into account an additional query a safety device from a single sensor. This not only leads to the saving of the previously mandatory in the prior art sensor on the securing device, but also simplifies a vehicle door lock necessarily provided in the interconnect structure. This mostly designed as a punched grid Consequently, printed circuit board construction can be implemented more simply and less costly in comparison to previous approaches. Here are the main benefits.
  • the safety device is regularly equipped with an actuating pin.
  • the actuating pin acts on the intermediate lever depending on the position of the safety device ("secured” or “unlocked”) at a user opening request. In the “secured” position of the securing device, the actuating pin performs a freewheeling action in relation to the intermediate lever. If, on the other hand, the safety device is "released” in its position, then the actuation pin acts on the intermediate lever. As a result, the intermediate lever is pivoted as described and operates the sensor. Following this, the opening drive starts and ensures the described electrical opening of the locking mechanism.
  • the safety device operates within the framework of the teaching of the invention manually or by manual application.
  • the safety device can of course also motor or electric motor in the various positions ("unsecured” and “secured") are transferred.
  • a manual actuator is recommended.
  • the securing device according to the invention also has an actuating element carrying the actuating pin.
  • the actuator is pivotally connected to the actuator.
  • the actuator is typically an actuator nut.
  • the actuator is usually designed as a control slide, which - as explained - hingedly connected to the actuating element or the operating nut.
  • the intermediate lever is usually a blocking lever.
  • the intermediate lever or blocking lever interacts with the opening drive.
  • the blocking lever ensures that any faulty energizing of the opening drive does not result in an undesired and possibly dangerous locking opening.
  • the blocking lever is usually with a blocking lug in engagement with the opening drive as long as no operator opening request is registered. If, however, it comes to such an operator opening request, the intermediate lever or blocking lever is acted upon and pivoted. As a result, then also the sensor undergoes a loading and controls the opening drive.
  • the safety device of the locking lever is mechanically coupled to a handle and / or an electric motor drive.
  • the handle or the electromotive drive each reflect the operator opening request.
  • the handle is pivoted or deflected or applied to the electric motor drive to pivot the blocking lever or intermediate lever.
  • the safety device in each case a freewheeling of the handle and / or the electric motor drive relative to the blocking lever instead.
  • the operating lever mechanism may also have at least one locking lever as its component. In normal operation, this locking lever consistently retains its "locked” position, as already described in the introduction. That is, the operation of opening the locking mechanism initiated by the opening drive "overrides the transition of the locking lever from its" locked “position to the” unlocked “position taken that the locking lever - in the so-called normal operation - its position "locked” consistently maintained. As a result, an unlocking of the opening drive is realized in the end. In other words, loading the opening drive (in normal operation) will cause the lock lever to maintain its "locked” position and not to be “unlocked” per se. So it is realized the mentioned unlocking lock.
  • a motor vehicle door lock is shown, which is equipped with a not explicitly shown locking mechanism.
  • the locking mechanism essentially consists of a catch and a pawl.
  • On the locking mechanism operates a release lever 1, which is pivotable about an axis 2. Pivoting movements of the release lever 1 in the illustrated clockwise direction in the FIG. 1 about its axis 2 cause a pawl is lifted from a catch and opens the catch spring-assisted.
  • an opening drive 3, 4 which is composed essentially of an electric motor 3 and an applied by the electric motor 3 driven pulley 4.
  • the driven pulley 4 is equipped on its back, not shown in the drawings with an actuating cam, which acts on the release lever 1 to open the locking mechanism.
  • the electric motor 3 operates on the driven pulley 4 in such a way that this about its axis 5 in the FIG. 1 indicated by an arrow counterclockwise movement performs.
  • the triggering lever 1 in turn clockwise about its axis 2
  • the locking mechanism is opened by means of the opening drive 3, 4.
  • an operating lever mechanism 6, 7 Of the operating lever mechanism, only one locking lever 6 and an intermediate lever 7 or blocking lever 7 are shown. Of course, belong to the operating lever mechanism 6, 7 even more not expressly mentioned lever on which it does not matter in the following consideration.
  • a sensor 8 which is presently designed as a switch or micro-switch 8.
  • the switch 8 can be acted upon by means of the intermediate lever or blocking lever 7.
  • the intermediate lever or blocking lever 7 is pivoted about its axis 2 in the clockwise direction.
  • the intermediate lever or blocking lever 7 is mounted coaxially to the release lever 1 on the common axis 2.
  • a clockwise movement of the intermediate lever or blocking lever 7 about the relevant axis 2 now leads to the blocking lever 7 acts on the sensor or switch 8 with an actuating nose 7a.
  • the associated switch position or change in the switch position is evaluated by a connected control unit as a switch or sensor operation and leads in the exemplary embodiment to the fact that the opening drive 3, 4 is acted upon.
  • a securing device 9, 10, 11, which is presently designed as a child safety device 9, 10, 11.
  • the securing device 9, 10, 11 can basically occupy two positions.
  • the securing device 9, 10, 11 At least in the position "secured” the securing device 9, 10, 11 (see. FIGS. 3 and 4 ) prevents the safety device or child safety device 9, 10, 11 an opening of the locking mechanism.
  • the sensor or switch 8 With the help of the sensor or switch 8 a total of an operator opening request is queried, as will be explained in more detail below. In fact, this operator opening request is implemented mechanically with the aid of the intermediate lever 7 of the actuating lever mechanism 6, 7. This is done within the scope of the invention in accordance with the position of the securing device 9, 10, 11th
  • the overall design is made such that the intermediate lever or blocking lever 7, which mechanically converts the operator opening request, depending on the position of the securing device 9, 10, 11, either acts on or does not act upon the sensor 8 activating the opening drive 3, 4.
  • the safety device or child safety device 9, 10, 11 is in its position "unlocked” or “child safety off” (see. Figures 1 and 2 ), so the operator opening request mechanically converting intermediate lever or blocking lever 7 can act on the sensor 8.
  • the securing device 9, 10, 11 is equipped with an actuating pin 11.
  • the actuating pin 11 acts on the intermediate lever or blocking lever 7 in the case of an operator request in the direction of the arrow shown in the figures in the sense of an upward movement.
  • the actuating pin 11 moves against the intermediate lever or blocking lever 7 and a blocking lug 7b, so that as a result of this movement of the intermediate lever or blocking lever. 7 is pivoted clockwise about its axis 2 and the sensor or switch 8 is actuated.
