Definitions

  • the invention relates to a door lock, especially for doors, Flaps or hoods of motor vehicles, with a lock latch, the between one releasing a locking pin and one of these locking position is pivotable, a pawl between one closed position locking the lock latch and one the lock latch releasing position is movable, and a motor-driven, circumferential driving pin, which with the drive switched on on its path the pawl in its release the lock latch Takes position and then runs against a stop that the pawl in its position releasing the lock latch holds in a position blocking the driving pin.
  • Such a door lock offers the possibility of the electric drive motor after unlocking the lock latch by monitoring the Shut off the motor's current draw when the drive pin runs against the stop and the power consumption due to the blocked motor increases.
  • Such an electronically monitored shutdown works more reliably than fault-prone microswitches.
  • the object of the invention is a door lock with opening aid to create that allows a more flexible spatial structure.
  • the task is through a door lock at the beginning described type solved, in which the stop on one separately block lever mounted by the pawl is arranged by the Pawl at their publishers in the position releasing the lock latch can be taken into its blocking position.
  • the solution according to the invention has the advantage that due to the separately stored block lever and the simplified pawl one More flexible spatial arrangement of the individual components is possible.
  • the Adaptation of the door lock to special spatial conditions and space restrictions, such as are common in the automotive sector are significantly simplified.
  • there is Possibility to vary between the pawl and the block lever to provide a gear ratio of the point of attack by which is the interaction between the block lever, the accumulating Driving pin and the pawl to reduce the occurring Forces can be influenced.
  • the drive motor drives a drive element which in a particular Angular range against the force of a spring relative to one on the same Rotary axis arranged drive plate is rotatable, on which the driving pin is arranged eccentrically.
  • the relative rotatability between drive element and drive plate avoids the action of the spring under all circumstances in the event of a defect in the electric drive motor, blocking the Pawl, which could result in the lock being affected no longer open or no longer close.
  • the driver pin remains in is determined by the preloaded spring moved into a position in which the pawl is free is movable, or the pawl can, for example, with a manual Emergency opening the driver pin in the way against the force Push the spring aside.
  • a Compression spring in a spring channel open on one side on the drive element or the drive plate is arranged and on a stop supported on each other component.
  • Such an arrangement of Compression spring is easy to assemble, resulting in particularly low manufacturing costs then arise if the drive element and the drive plate are made of plastic and the spring channel and Stop are formed on the respective component.
  • the driving pin may be made of plastic, higher ones
  • loads are a metal driving pin or a bolt of advantage in the area of the contact surface with the pawl and the stop is provided with a metal pad.
  • a bias of the Spring can be useful, also to improve the hold of the Spring in the spring channel.
  • a second stop is also provided, which with the Back wall of the spring channel interacts and the relative rotatability between the drive element and the drive plate limited against the biasing direction of the compression spring.
  • This second Stop ensures that there are not undefined relative positions can come between the drive element and the drive plate, that could be detrimental to the function.
  • the spring channel with simple Structure extends over an angular range of approximately 90 ° and from two lateral, arcuate walls is limited.
  • the angular range 90 ° of the extension of the spring channel allows a preload the compression spring then located by approximately 45 °, an angular range, which is special to avoid malfunctions has proven expedient.
  • the lock latch is opened in the direction of its spring Position and / or the pawl by a spring towards its the Lock latch locking position are preloaded.
  • the lock latch when closing the tailgate of the vehicle, for example through the locking pin against the force of the return spring in their closed position is movable, the pawl against the force their return spring in their position releasing the lock latch.
  • the closed position of the lock latch In the closed position of the lock latch is supported under the load of its Preload spring on a catch on the pawl, while the Pawl on a suitably shaped when the lock latch is open Support the stop on the lock latch.
  • a particularly simple embodiment provides that a single Spring between the lock latch and the pawl both elements preloaded.
  • a door lock 10 is shown schematically, for example Use in the automotive sector for doors, flaps or hoods finds.
  • the door lock 10 has a rotary latch Lock latch 12, which has a locking pin arranged on the body side (not shown) locked in their closed position. In this locking position is the lock latch 12 with a locking lug 14 against a catch 16 locked on a pawl 18 which is pivotable about an axis of rotation 20 is stored.
  • tension spring 22 is provided, which the lock latch 12 in Direction of their open position against the detent 16 and the pawl 18th to support the locking of the lock latch 12 against a pressure flank 24 preloaded on the lock latch 12.
  • the pawl 18 and the Lock latch 12 are one possible omission, for example Locking position between the lock latch 12 and the pawl 18 for Simplified improvement of clarity.
  • the door lock 10 also via an opening aid 26.
  • This has a drive element 28, which is driven by an electric drive motor (not shown) is, for example, via a worm in a worm gear molded external toothing 30 engages on the drive element 28.
  • the drive element is mounted so as to be rotatable about an axis of rotation 32 which is also rotatably mounted a drive plate 34.
  • the Driving plate 34 can be rotated relative to drive element 28, the relative twist between these two elements against the force of a compression spring 36 takes place.
  • the compression spring 36 is arranged in a spring channel 38 which is open on one side, the with respect to the viewing direction in Figure 1 at the bottom of the Driving plate 34 is formed.
  • the spring channel 38 extends over an angular range of approx. 90 ° and is defined by two lateral quarter-circular walls 40 and a rear wall 42 are formed.
  • the drive element 28 acts on the free via a spring stop 46 End of the compression spring 36, which creates the required moments on the Drive plate 34 are transferable.
  • a second stop 47 am Drive element 28 limits the relative rotatability between the Drive element 28 and the drive plate 34 against the drive direction, to undefined relative positions between these two Elements to avoid.
  • the door lock 10 has a pivoted Block lever 48, which has a stop 50 on a first lever arm 52 and has a second lever arm 53 which is connected to the pawl 18th cooperates.
  • the door lock 10 according to FIG. 1 is in the locked rest position, the driver pin 44 outside the Engagement area of the pawl 18 and the block lever 48 is.
  • the Compression spring 36 is maximally relaxed, but it is in one prestressed state.
  • the relative mobility between the drive plate 34 and the Drive element 28 ensures that the driving pin 44 also at a failure of the electric drive motor not the lever arm 54 Block pawl 18 or the first lever arm 52 of the block lever 48 can.
  • the door lock 10 can have further functions, for example an automatic closing aid for the door, which can be implemented in the usual way can.
  • the door lock can also be used outside the motor vehicle sector is easily conceivable.
