Definitions

  • the invention relates to a motor vehicle door lock, with a locking mechanism, and with a drive for the locking mechanism, in particular for the electrical opening / closing of the locking mechanism, wherein the drive is equipped with at least one drive element which works directly or indirectly on the locking mechanism.
  • the drive for the locking mechanism generally ensures that it is opened electrically.
  • the drive via the drive element works directly or indirectly on a pawl as part of the locking mechanism of pawl and rotary latch. Since the drive in general and beyond has an electric motor, one speaks in this context also of the electrical opening of the locking mechanism.
  • Electric opening drives are usually realized in connection with a so-called "keyless entry" access.
  • the pawl is lifted off its engagement with the rotary latch with the aid of the electric opening drive with the locking mechanism closed (compare, for example, only DE 10 2007 01 1 498 A1).
  • the pawl In the closed state of the locking mechanism, the pawl generally falls first in a pre-rest and then a main catch of the catch. In order to open the ratchet, therefore, the pawl must be lifted from its engagement with the catch. This is ensured by the drive or opening drive during electrical opening.
  • the impingement of Gesperres using the drive can be done directly or indirectly.
  • Indirect loading provides that the drive acts on the pawl via an interposed release lever and this is then lifted off its engagement with the rotary latch.
  • the procedure is such that the drive directly lifts the locking pawl from its engagement with the rotary latch.
  • the offset for example, in rotations drive element may be equipped with an actuating cam, which operates directly on the pawl and lifts them from their engagement with the catch.
  • the drive is not an opening drive, but rather a closing 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 so that an actuation of the locking mechanism is still possible and can be carried out, for example, if the drive fails.
  • a generic motor vehicle door lock in the invention is characterized in that a mechanical actuator for emergency operation of the drive element is provided.
  • This is generally done by manual loading of the actuator in question.
  • the emergency operation corresponds to the emergency closing of the locking mechanism.
  • the actuating element for emergency closing of the locking mechanism is established.
  • the mechanical actuating element can also be provided for emergency opening of the locking mechanism.
  • the mechanical actuator after a manual application again ensures that the blocked during the closing process or otherwise halted drive element is again moved back to its normal position mechanically. 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. That is, a blocked in the "open" position electric drive to open the locking mechanism is mechanically reversed by means of the mechanical actuator to its normal position. Since the basic position corresponds to the fact that the drive usually does not act on the locking mechanism, the locking mechanism can then be mechanically closed without difficulty. The same applies to the associated motor vehicle door.
  • the actuator is formed Schlosseigen.
  • a castle-own actuator designates such, which is designed as part of the motor vehicle door lock according to the invention, and indeed already in the production.
  • the actuator in question may be stored in or on the associated lock housing.
  • the procedure is the same.
  • the actuating element acts radially on the drive element to its rotation.
  • the invention is based on the recognition that the drive element is set as part of the drive by means of an electric motor as a further component of the drive in rotation. In normal operation, rotations of the drive element cause the ratchet to be opened electrically.
  • the drive element is typically equipped with an actuating cam which operates directly or indirectly on the pawl of the locking mechanism.
  • the drive element and the actuating element are advantageously equipped with a respective toothing.
  • the drive element has a peripheral toothing and is consequently designed as a worm wheel.
  • the electric motor in turn has on its output shaft via an output worm, which meshes with the peripheral toothing of the drive element or worm wheel.
  • the drive element or worm wheel for electrical opening can be set in rotation and lift the pawl as described from their engagement with the rotary latch. This is how it works in normal operation.
  • the two gears do not engage in one another on the one hand the drive element and on the other hand the mechanical actuator for emergency operation. That is, in normal operation, the mechanical actuator for emergency operation and advantageous for emergency closing can not interact with the drive element. Only when an emergency operation or emergency closure is required, the two gears mesh with each other.
  • the teeth of the actuator is equipped with a recess.
  • the design in this case is such that the recess in the toothing of the actuating element of the toothing of the actuating element is opposite in normal operation. Since the recess of the actuating element and the associated toothing of the drive element consequently do not mesh with one another, the drive element can perform pivoting movements in normal operation, independently of the actuating element. Only then, when an emergency operation or an emergency operation is required, a manual action on the mechanical actuator ensures that the teeth on the actuator in question is brought into engagement with the toothing of the drive element. This is done by an operator by the already described manual loading of the mechanical actuator.
  • the design is generally made such that the recess in the toothing of the actuating element is designed as a largely circle segment. Consequently, the toothing of the actuating element also passes over a circular segment.
  • the overall design is made so that the circle segment of the toothing of the actuating element is designed to be larger overall, typically twice as large as the circle segment belonging to the recess of the toothing. That is, a generally realized in this context actuating screw is divided in the ratio of one third to two thirds, with one third of the circumference belongs to the recess and two thirds to the teeth.
  • the normal operation of the drive element is provided, which in normal operation with the actuator or the mentioned actuating screw can not interact.
  • Only in emergency operation and emergency operation or emergency closing of the drive element engages the corresponding worm turns equipped circle segment of the actuating screw in the drive element.
  • a two-thirds circular revolution is sufficient to apply the drive element at least as far as manually with the aid of the actuating element or the actuating screw, so that the pawl is not (more) held in its lifted position compared to the rotary latch.
  • the pawl can easily occur in a subsequent mechanical closing operation in the locking mechanism or the catch, first in the Vorrast and then in the main catch.
  • the catch is thereby - as usual - transferred by a retracting into the inlet opening of the catch bolt in its closed position.
  • the actuating element generally has the actuating screw arranged tangentially on the drive element.
  • the actuating worm interact with the peripheral toothing of the drive element comparable, as does the output worm on the output shaft of the electric motor.
  • the actuating element is in two parts equipped with the actuating screw in question and in addition a manually acted upon manipulation element.
  • the manipulation element and the actuating screw are arranged at an angle to each other. This is explained essentially by the fact that the actuating screw is arranged as part of the actuating element tangentially compared to the drive element.
  • the manipulation element advantageously has an actuating nut.
  • the actuating nut can be mounted for example in the lock housing and / or lock case. As a result, the Betuschistsnuss is easily accessible from the outside.
  • the invention is based on the recognition that the inlet mouth is directly accessible in case of emergency closure. Because the emergency closure requires that the locking mechanism is permanently open and can not be closed. Consequently, the motor vehicle door and in particular the inlet mouth is accessible. An operator can act on the accessible inlet mouth now the operating nut so that the drive element and with him the entire drive undergoes the described emergency closure. As a result, the pawl is not (more) lifted from the catch.
  • the locking pin which enters the inlet mouth and subsequently interacts with the rotary catch ensures that the rotary latch is transferred to its closed position. Since the pawl has left its lifted position, it can first come into the pre-rest and then the main catch of the catch as desired and the associated motor vehicle door is locked as desired. As a result, any theft of the motor vehicle is effectively prevented. Nevertheless, the motor vehicle door can generally subsequently be opened again, for example via an intended lock cylinder, if the electric opening drive is still defective. Other measures for emergency opening are conceivable.
  • a motor vehicle door lock which is equipped with a particularly simple design actuator in particular for emergency closing. Because the mechanical actuating element used for emergency actuation of the drive element used at this point does not require any modifications to the otherwise maintained electric drive. Rather, it is sufficient if the actuating screw is arranged as part of the two-part actuator tangentially compared to the drive element. An additional manipulation element ensures the appropriate loading of the actuating screw.
  • the mechanical actuating element used for emergency actuation of the drive element used at this point does not require any modifications to the otherwise maintained electric drive. Rather, it is sufficient if the actuating screw is arranged as part of the two-part actuator tangentially compared to the drive element. An additional manipulation element ensures the appropriate loading of the actuating screw.

  • the electric drive 5 to 9 is used here to open the locking mechanism 3, 4.
  • the drive is 5 to 9 from an electric motor 5 and an output worm 6 on an output shaft of the electric motor 5 together.
  • the output screw 6 meshes with a drive element 7 as a further component of the electric drive 5 to 9.
  • the drive element 7 in the exemplary embodiment is a worm wheel 7, which is equipped with an external peripheral toothing 14.
  • the output worm 6 on the output shaft of the electric motor 5 engages with its individual worm turns in the outer peripheral toothing 14 of the worm wheel 7 and can put in this way the worm wheel 7 in rotation.
  • In the exemplary embodiment corresponds to an opening of the locking mechanism 3, 4, a rotation of the worm wheel 7 in the indicated clockwise direction, and indeed so far until an arranged on the worm wheel 7 actuating cam 8 can operate on a trigger lever 9. As soon as the actuation cam 8 acts on the release lever 9 as shown in FIG.
  • the described electric or electric motor drive 5 to 9 in the open position of the locking mechanism 3, 4 as shown in FIG. 1 are, for example, because the electrical power supply to the electric motor 5 is interrupted, fails or otherwise as the electric drive blocked to 9, so equipped with the corresponding motor vehicle door lock motor vehicle door can not (more) be closed.

This is evident in particular with reference to FIG. 3.
  • the retracting into the inlet mouth 16 locking pin interacts with the rotary latch 4, which is transferred to its closed position. Since the pawl 3 is no longer lifted, they can first come into the Vorrast and then the main catch of the catch 4.
  • the locking mechanism 3, 4 can be closed mechanically as usual. It can be seen on the basis of FIG. 3 that the recess 15, on the one hand, and the teeth or worm threads 13 of the actuating worm 10, on the other hand, cover and occupy different circle segments of a full circle.
