Definitions

  • the invention relates to a lock with an auxiliary motor, in particular a door lock for a motor vehicle, with the features specified in the preamble of claim 1.
  • Such a lock with auxiliary motor is known from DE-OS 34 01 842, which is provided for closing a motor vehicle door, a motor vehicle hood or the like.
  • a relocatable lock latch is provided, which engages behind a locking block in a pre-locking and a main locking position. Closing the vehicle door, vehicle hood or the like can be made more difficult, for example, by a sealing element which is elastically deformed shortly before it is completely closed, thereby causing a resistance force in the opening direction. The resistance during closing is overcome by an auxiliary motor which, when the latch is in the main latching position, shifts the locking block from a pre-closing position to a main closing position.
  • the vehicle door, vehicle hood or the like can be easily closed as a result, but for this purpose either an elaborate straight guide for the locking block or a support receiving the locking block or a pivotable support for the locking block is required, which requires a corresponding free space for pivoting.
  • the lock also requires large free spaces for a cable pull with a pulley interacting with the locking block, as a result of which the installation space is significantly increased.
  • the durability of the cable is impaired by several deflection rollers and large deflection angles, which requires a relatively large diameter due to the high force transmission and the impact loads transmitted from the lock latch to the lock block when closing.
  • a precaution must also be taken so that the cable is always taut, otherwise the locking block can make small movements which, when the lock is used on a motor vehicle, cause rattling noises while driving.
  • the invention has for its object to provide a lock with an auxiliary motor according to the preamble of claim 1, which has a simple structure and requires little space.
  • the component to be locked with the lock should be reliably held.
  • the lock shown in Fig. 1 is provided on a vehicle door of a motor vehicle and has a lock latch designed as a fork latch 1.
  • the fork latch 1 can be pivoted on a lock plate 2 connected to the vehicle door from an open position via a pre-latching position into the main latching position shown, in which a locking bolt 3 or the like is engaged by a leg 4 of the fork latch 1 in a known manner.
  • the fork latch 1, which has a preliminary latch 5 and a main latch 6, is secured in the main latching position shown from a pawl 8 which can be pivoted about the axis 7 between a release position on the lock plate 2 between a release position which releases the fork latch 1 and the locked position shown, before being displaced into the open position.
  • the pawl 8 is loaded by a leg spring 9 shown by a dash-dotted line in the locked position and the fork latch 1 by a spring, not shown, in the open position.
  • the locking bolt 3, which is circular in cross section, is rotatably arranged about an axis 11 which is eccentric to its axis 10 on a locking wedge 12 which is fastened to a vertical column of a door frame receiving the vehicle door.
  • FIG. 1 the position corresponding to FIG. 1 of the vehicle door 13 relative to the column 14 of the door frame receiving the vehicle door 13 is illustrated in a basic illustration. How be already executed, are in this position the locking pin in its pre-closed position and the fork latch in its main click position.
  • the locking bolt 3 can be moved from an auxiliary motor, not shown, by an angle of approximately 180 degrees about the eccentric axis 11 parallel to the axis 10 of the locking bolt 3 from the pre-closing position shown in FIG. 1 to the main closing position shown in FIG. 2.
  • the locking wedge 12 is relatively H, which is twice the eccentricity E of the axis 10 of the locking bolt 3 compared to its eccentric Axis 11 corresponds to the fork latch 2.
  • the relative path of the locking wedge 4 relative to the fork latch 2 is shown in FIG. 2.
  • the locking bolt 3 can be rotated in the reverse position from the auxiliary motor (not shown) from its main closing position corresponding to FIG. 2 into the pre-closing position according to FIG. 1. Since, in the exemplary embodiment, the locking bolt 3 is in a dead center position in the pre-closing position and in the main closing position, the motor movement of the vehicle door from the pre-closing position into the main closing position and vice versa into the pre-closing position is particularly harmonious in the course.
  • a door seal arranged in the door frame is elastically deformed, which thereby causes a resistance force loading the vehicle door into the open position.
  • the vehicle door can be closed easily, since a slight door knock is sufficient to move the vehicle door into the pre-closing position and with the support of the auxiliary motor from the pre-closing position against the resistance of the door seal to the main closing position.
  • the exaggerated play shown in Figures 1 and 2 between the locking pin 3 and the legs 4, 4, the fork latch 1 is in reality only slight in the exemplary embodiment, so that no or almost no noise occurs when the locking pin 3 is rotated.
  • the vehicle door is also supported by the striker 12 in a manner known per se.
  • a switch 15 shown symbolically in FIGS. 1 and 2 detects the latching position of the fork latch 1 when the lock is closed and switches the auxiliary motor on in the pre-closing position until the main closing position is reached. Since the fork latch 1 is already in its main latching position and the locking blade 8 is in its locking position, no further displacement of the parts is necessary to ensure that the locking latch 8 secures the fork latch 1 against shifting to an open position.
  • the auxiliary motor not shown, is formed in the exemplary embodiment by an electric motor and a downstream transmission which interacts, for example, with a gearwheel connected to the locking bolt 3.
  • the closing wedge 12 used in the exemplary embodiment is shown in an enlarged plan view in FIG. 3.
  • the closing wedge 12 has three legs 12a, 12b, 12c directed laterally towards the outside A.
  • the locking bolt 3, shown by solid lines in the pre-closing position and by broken lines in the main closing position, is arranged between the two legs 12a, 12b and is pivotably connected to the legs 12a, 12b about an eccentric axis 11 formed on the two legs 12a, 12b.
  • the third leg 12c which forms a protection for the locking bolt 3, lies opposite a vertical end face of the vehicle door, not shown.
  • the leg 12a in FIG. 3 is connected to this column 14.
  • the lock can be implemented in numerous versions that differ from the exemplary embodiment.
  • the lock latch designed as a fork latch in the exemplary embodiment can be designed as a sliding latch. Designs are also conceivable in which the lock latch cannot be secured by a pawl before being moved into an open position. Rotation of the locking bolt from the pre-closing position to the main closing position and, if appropriate, from the main closing position to the pre-closing position can also take place with a different twisting angle in a desired direction of rotation, deviating from the particularly advantageous twisting angle of 180 degrees. It is also not necessary for the locking bolt to be fastened to a locking wedge.
  • the striker does not deviate from the exemplary embodiment on both end regions, but only on one end area is rotatably mounted eccentrically.
  • the cross section of the locking bolt is preferably circular.
  • other cross-sectional shapes of the locking bolt are also possible, the cross-sectional shape being able to control the relative movement of the locking bolt with respect to the lock latch.
  • the lock is also suitable for other applications in which, for example, a component which can be locked by the lock is difficult to close.
