Definitions

  • the invention relates to a motor vehicle door lock, with a locking mechanism and with a mechanical lever mechanism and a motorized opening unit, which are each individually set up to open the locking mechanism.
  • motor vehicle door locks have become known, for example, from the relevant state of the art according to DE 20 2008 003 845 U1 of the Applicant or from DE 196 42 698 A1.
  • the procedure is such that, under normal conditions or normal operation, a handle part of a door handle is fixed in its basic position. After unlocking the door lock, an associated vehicle door without pivoting of the handle part can be opened by simply pulling the handle.
  • the invention is based on the technical problem of further developing a motor vehicle door lock of the structure described at the outset so that, with perfect functionality, there is the additional possibility of mechanically supporting the per se motor opening process. In addition, this should succeed in a structurally simple and inexpensive construction.
  • a generic motor vehicle door lock in the invention is characterized in that the motorized opening unit in normal operation specifies a freewheeling of the lever mechanism relative to the locking mechanism and provides in opening operation for its engagement with the locking mechanism.
  • the normal operation corresponds to the fact that the motor vehicle door lock or its locking mechanism is not opened and also take appropriate measures.
  • the opening operation means that the ratchet undergoes an opening by lifting a pawl from an associated ratchet. Because this process has the consequence that a previously captured by the catch locking bolt is released. Since the locking bolt is usually connected to a motor vehicle door, this process corresponds to the fact that an associated motor vehicle door, motor vehicle door, etc. can be opened. That is desired.
  • unintentional openings should be omitted. Such unintentional openings can be caused, for example, in an accident or in the event of a crash by the acceleration forces occurring there. According to the invention, such unintentional openings are not allowed because the motorized opening unit ensures that the mechanical lever mechanism in the associated normal operation (this also belongs
  • any operations of the mechanical lever mechanism result in normal operation (even in a crash) in associated pivoting movements, but free running or idling relative to the locking mechanism, so do not cause the pawl to lift off the catch or take off. An unwanted opening of the associated motor vehicle door is therefore excluded.
  • the locking mechanism Only when and only if the motor opening unit is actuated by a corresponding opening command is given to an electric motor of the motor opening unit, the locking mechanism is opened. Because in this case, the opening operation is present and the motor opening unit ensures that the mechanical lever mechanism is brought into engagement with the locking mechanism. Then, an action on the mechanical lever mechanism causes the pawl is lifted from the catch and can also be lifted.
  • the motorized opening unit provides for the opening of the locking mechanism during opening operation. Rather, the locking opening is supported by the lever mechanism then engaged with the locking mechanism. In most cases, in this context, even a minimal Verfahrwerg of the electric motor of the motor opening unit is sufficient, so that the mechanical lever mechanism comes into engagement with the locking mechanism. As a result, even situations can be mastered without problems, in which, for example, the force of the electric motor is not sufficient to lift the pawl as such from the catch. Because this process is mechanically supported according to the invention.
  • a spring which is usually provided in addition in this context on the drive, ensures that the motorized opening unit is acted upon in the opposite direction to the (unidirectional) drive direction. This allows the motorized opening unit with the help of the spring after the loss of the drive easily in their original position (again) convict. This corresponds to the normal operation and consequently the freewheel of the lever mechanism relative to the locking mechanism. Either way, the locking mechanism can be easily and reliably opened in any case as a result of the realized mechanical redundancy. Because it is sufficient that the electric motor of the motor opening unit completed only a small travel, which as such is not or not enough for lifting the pawl of the catch sufficient or sufficient.
  • the mechanical lever mechanism has an interacting with the locking mechanism release lever. That is, the release lever located immediately near the ratchet provides the core
  • the release lever usually has a contour for a pin engaging therein, this pin is usually formed as a mechanical connecting pin between the pawl and the release lever.
  • this pin may be mounted on a slide or in a slot, which is arranged between the release lever and the pawl. The pin is perpendicular to this gate and mechanically connects the pawl to the release lever.
  • the contour in the release lever is typically formed in two parts. In fact, the contour is usually subdivided into a freewheeling area and an engagement area. In this case, it has further proven, if the contour is designed L-shaped. Because in this context, one L-leg acts as a freewheeling area, while the other L-leg is formed as an engagement area.
  • the L-leg designed as a freewheeling area is typically the vertical L-leg, whereas the L-leg defining the engagement area is designed as a horizontal L-leg.
  • the connecting pin between the pawl and the release lever in the freewheel area or the associated L-leg of the L-shaped contour in the release lever the release lever can be pivoted about its axis without these pivotal movements are transmitted to the pawl. Rather, the pin in question moves in this process along the freewheel area or along the vertical L-leg. The pivoting movements of the release lever thus go empty.
  • the mechanical lever mechanism runs free. Normal operation corresponds to this.
  • the release lever and the pawl of the locking mechanism are designed coaxially with each other.
  • the release lever and the pawl are usually received together on the matching axis in a lock case of the door lock.
  • the motorized opening unit operates unidirectionally and has an electric motor. This electric motor works on a driven by him drive pulley.
  • the drive pulley as such usually carries an eccentric.
  • the eccentric is usually designed as a drive cam.
  • the drive cam on the one hand interact with a stop element on the Sperrkiinke and on the other hand with an actuating element. As soon as the drive cam moves against the stop element on the blocking line, the pawl is lifted off the catch by means of the drive cam.
  • Rotary latch can open as a result of this.
  • the drive cam on the other hand ensures that the already mentioned actuating element is acted upon.
  • the actuator ensures the position changes of the pin or the mechanical connecting pin between the pawl and the release lever.
  • the pin can be placed on the one hand in the freewheeling area of the contour of the release lever and on the other hand in its engagement region. This defines both normal operation and the opening operation.
  • the actuator works on the pin. For this purpose, the actuator is acted upon by the motor opening unit in turn.
  • the actuator operates on the pin such that the pin is arranged in normal operation in the freewheeling area and in the opening operation in the engagement region of the contour on the release lever.
  • the adjusting element is advantageously designed as a pivot lever.
  • the actuator or the pivot lever is thus functionally between the motor drive and the pin or connecting pin.
  • the adjusting element may be arranged between the pawl and the release lever and act directly on the pin bearing the backdrop.
  • the adjusting element or the pivot lever is generally mounted approximately centrally on an axle.
  • One end of the pivot lever is equipped with a stop or stop pin on which abuts the eccentric of the motor opening unit to pivot the pivot lever.
  • the pivot lever mechanically couples the eccentric of the drive disc of the motorized opening unit with the pin.
  • Fig. 2 shows the object of Fig. 1 in the opening operation.
  • a motor vehicle door lock is shown, which is constructed in its basic structure with a ratchet 1, 2 of a rotary latch 1 and with the rotary latch 1 in a manner usually interacting pawl 2.
  • the ratchet 1, 2 may also have a pawl lever 2 instead of the pawl 2 shown, which then interacts with a pawl, not shown in the usual manner.
  • the functionality of the pawl lever 2 in question corresponds to that of the pawl 2 in the following considerations.
  • the lever with the reference numeral 2 may basically be a pawl lever 2, which operates on a pawl, not shown, which in turn interacts with the catch 1.
  • this pawl lever 2 is not realized, but rather the figured pawl 2. All functions described below, however, both with respect to the pawl 2 shown and to the alternative pawl lever 2 in the context of the example not shown conceivable and are encompassed by the invention.
  • FIG. 1 now shows the normal operation of the motor vehicle door lock with the pawl 2 sunk in relation to the rotary latch 1.
  • a merely indicated locking bolt 3 is caught and an associated motor vehicle door (not shown) is closed.
  • FIG. 2 represents the opening operation.
