Definitions

  • the invention relates to a motor vehicle door lock, with a locking mechanism, and to a drive for the locking mechanism, in particular for electrical opening / closing, wherein the drive is equipped with at least one drive element which operates directly or indirectly on the locking mechanism.
  • Motor vehicle door locks with additional drive for opening or closing a locking mechanism are increasingly used in practice and extensively described in the literature.
  • the generic type DE 10 2015 205 951 A1 deals with such a motor vehicle door lock, in which the opening of the locking mechanism is carried out with the aid of a first electric drive.
  • a second electric drive is provided, which works as a closing aid, thus responsible for closing the locking mechanism.
  • An electric opening drive usually ensures after actuation of an outside door handle or inside door handle or in a "keyless entry" dialogue by an associated sensor signal and when it is triggered that the locking pawl is lifted from its engagement with the locking mechanism when the locking mechanism is closed
  • the pawl engages a pre-catch or main catch of the catch.To open the ratchet, therefore, the pawl must be lifted from its engagement with the ratchet.
  • Actuation of the locking mechanism with the aid of the drive can be indirect or immediate, for example, an indirect action provides that the drive acts on the locking pawl via an intermediary release lever and then pushes it away from its lever ngriff is lifted with the catch.
  • the drive is one for closing the locking mechanism, it is generally the case that the drive acts on the rotary latch. As soon as the locking mechanism assumes, for example, its pre-locking position with the pawl engaged in the pre-catch of the rotary latch, the drive ensures that the rotary latch is pivoted in the direction of the main catch. In this way, the drive ensures a closing of the locking mechanism.
  • the invention is based on the technical problem of further developing such a motor vehicle door lock in such a way that an actuation of the locking mechanism is still possible and can be carried out even if the drive has failed, for example.
  • a generic motor vehicle door lock in the context of the invention is characterized in that a mechanical actuating element is provided for the emergency actuation of the drive element.
  • the emergency operation corresponds to the emergency closing of the locking mechanism.
  • the mechanical actuating element can also be set up and provided for the emergency opening of the locking mechanism.
  • the mechanical actuator ensures again that the blocked during the closing process or otherwise stopped as drive element is again moved back mechanically to its normal position. As a result, a permanent closure in the course of an emergency opening can be lifted.
  • the drive for the locking mechanism is, in particular, a drive for electrically opening the locking mechanism, so that the mechanical actuating element is provided and set up for emergency closing of the drive element.
  • the actuator is closed-lock and / or formed lock foreign.
  • a lock-own actuator designates such, which is designed as part of the motor vehicle door lock according to the invention.
  • the actuating element in question may be mounted in or on the associated lock housing.
  • a lock-foreign actuating element is understood to be one which is formed independently of the motor vehicle door lock. In order to interact with the locking mechanism mounted inside the motor vehicle door lock, it is therefore necessary to position the equally external and independent lock-external actuating element in such a way that in the described example case it is able to actuate the drive element for emergency closing.
  • the actuating element is formed in two parts.
  • the mechanical actuator is generally composed of a lock's own operating lever and a non-locking operating tool. While the lock's own operating lever is mounted in or on the lock housing of the motor vehicle door lock, the lock-external operating tool is completely independent and self-sufficient designed in comparison to the motor vehicle door lock according to the invention.
  • the operating lever is a push or push lever. That is, the actuating lever in question can be generally linearly reciprocate compared to the lock housing.
  • the actuating lever is acted upon either thrust or pressure. The corresponding thrust or pressure is advantageously exerted on the actuating lever with the aid of the actuating tool. As a result, the actuating lever normally performs a linear movement.
  • this neutral or basic position corresponds to the fact that the drive does not act on the ratchet and, in particular, the pawl is free of the drive. Consequently, the pawl is not (more) lifted from the catch and can easily occur in an example, manual closing of the associated motor vehicle door in the pre-catch or main catch of the catch.
  • this neutral or basic position corresponds to the fact that the drive does not act on the ratchet and, in particular, the pawl is free of the drive. Consequently, the pawl is not (more) lifted from the catch and can easily occur in an example, manual closing of the associated motor vehicle door in the pre-catch or main catch of the catch.
  • the main benefits are the main benefits.
  • the actuating tool optionally engages through an opening in the lock housing. Since it is in the process of emergency closure to an absolute exceptional case, the opening in the lock housing can be opened basically and once in this process or, for example, a window closing the opening using the operating tool or otherwise destroyed. In principle, it is also possible that the opening is designed to be closed. In this case, the invention is based entirely on the knowledge that the lock housing to hold, inter alia, the lock as close as possible - except for an area near the inlet mouth - must be designed closed to prevent any environmental influences, the ingress of water, etc. As a particularly preferred variant has been found, in which the opening for the passage or engagement of the actuating tool in the region of said inlet mouth is arranged.
  • the invention is based on the recognition that upon realization of a drive for electrically opening a locking mechanism and its failure, the associated motor vehicle door is forcibly opened and can not be closed.
  • the inlet mouth is accessible.
  • a lock holder usually provided on the body side can interact with the locking mechanism arranged in the interior of the lock housing.
  • the arrangement of the opening in question in the inlet mouth not only an exposed and easily accessible position for the insertion of the actuating tool is provided. But an existing at this point or after the intervention of the operating tool inevitably adjusting opening can be fundamentally hurt, because the lock housing is anyway at least partially open in the region of the inlet mouth.
  • the procedure is such that the actuating element engages in total on a journal of the drive element.
  • the drive element is designed as a worm wheel meshing with an electric motor. Because provided the castle's own operating lever previously performs described linear movement, can be easily pivot over the actuating lever acting on the pin designed as a worm gear drive element. A pushing or pushing movement for acting on the actuating lever thus leads directly to a rotational movement of the worm wheel and, overall, to the worm wheel being reversely moved back to its basic position or neutral position mechanically with the aid of the actuating element or the actuating tool acting on the actuating lever.
  • the electric motor meshes with the worm wheel as a further component of the drive, the electric motor is easily taken along in the rotary movement of the worm wheel described, especially since low frictional forces are typically observed at this point. That is, within the scope of the invention, with the aid of the actuating element, the drive for the locking mechanism, in particular for electrical opening, can be easily moved back mechanically into its basic position or initial position, even and in particular in the event that the drive in any way "hangs" during the opening process In this way, emergency closing of the drive element and consequently of the drive as a whole can be achieved with the help of the mechanical confirmation element. As a consequence, the locking mechanism can subsequently be mechanically closed without any problem, and the same applies to a corresponding motor vehicle door, in which the main advantages are to be seen.
  • FIG. 1 shows the motor vehicle door lock according to the invention in a schematic view with the drive stopped
  • FIG. 2 the motor vehicle door lock according to FIG. 1 in the course of an emergency operation or emergency closure.
  • a motor vehicle door lock is shown.
  • the motor vehicle door lock generally has a merely indicated lock housing 1.

  • the locking mechanism 2, 3 is composed as usual of a pawl 2 and a rotary latch 3.
  • the drive 4, 5, 6, 7 is composed in the embodiment of an electric motor 4 and a drive element 5, which in the present case is a meshing with the electric motor 4 worm wheel 5.
  • Tastsambalich engages the electric motor 4 with its output-side shaft or a worm there arranged in a circumferential toothing of the
  • the worm wheel 5 carries on at least one surface an actuating contour 6. With the aid of the actuating contour 6, a trigger lever 7 can be pivoted about its axis B.
  • the electric motor 4 acts on the drive element or worm wheel 5 such that it performs a clockwise movement about its axis A.
  • the actuating contour 6 comes to rest on the trigger lever 7.
  • the trigger lever 7 performs about its axis B, a counterclockwise movement, as indicated in FIG.
  • the counterclockwise movement of the release lever 7 about its axis B ensures that in the closed position of the locking mechanism 2, 3, the pawl 2 is lifted from its engagement with the rotary latch 3.
  • the locking mechanism 2, 3 can be opened electrically in total. In fact, it is only necessary for the electrical opening that the drive 4, 5, 6, 7 receives a corresponding opening command.
  • the drive 4, 5, 6, 7 and the electric motor 4 is connected to a control unit 8, which in turn evaluates a signal of an outside door handle or door inner handle 9 or a local sensor.
  • the sensor can usually be a switch.
  • the switch operation and its registration by means of the control unit 8 ensures that the drive 4, 5, 6, 7 - as described - to open the locking mechanism 2, 3 is applied. If, during the described opening operation, the drive 4, 5, 6, 7 for the locking mechanism 2, 3 is not permanently energized or mechanically blocked, scenarios are conceivable such that the drive 4, 5, 6, 7 in the Position according to FIG. 1 stops.

  • the locking mechanism 2, 3 (not) can be closed. Because the release lever 7 acts on the pawl 2 permanently such that it is lifted from its engagement with the rotary latch 3 and remains. In order nevertheless to be able to close the motor vehicle door lock and the locking mechanism 2, 3 and consequently a motor vehicle door equipped therewith, it is possible according to the invention to carry out an emergency closure with the aid of a mechanical actuating element 10, 11.
