Definitions

  • the present invention relates to a locking device for a vehicle according to the preamble of claim 1.
  • the WO 200686277 A2 also describes a locking device for a vehicle, in which a closing element in the form of a striker, into which engages a catch for locking, is arranged displaceably. Again, a locking device for the displacement mechanism of the striker is provided.
  • the EP 1 257 721 B1 discloses a power-operated closing piston with knee lever-like actuating mechanism, wherein the design of a corresponding rotary latch assembly is not discussed.
  • Locks for motor vehicles are practically known since the beginning of motor vehicle construction. Such locks usually have a striker or locking pin which is fixed to the body and immovably arranged and in which a arranged on a vehicle door or a trunk lid movable catch engages to lock the vehicle door or the boot lid.
  • a striker or locking pin which is fixed to the body and immovably arranged and in which a arranged on a vehicle door or a trunk lid movable catch engages to lock the vehicle door or the boot lid.
  • the sealing arrangements used are characterized more voluminous and stiffer against deformation.
  • this has the disadvantage that a considerable force must be expended, for example, to close a corresponding vehicle door or a manual closing in an extreme case is no longer possible reproducible.
  • the locking devices are partially by means of a power-operated, so for example, with an electric motor driven closing element, such as a striker or locking pin, provided, whereby the closing element, after it was brought over a comparatively lower force with the catch in the closing direction of the vehicle door or a trunk lid or a cover is moved away to exert a corresponding force on the seals and complete the closing operation.
  • an electric motor driven closing element such as a striker or locking pin
  • some pawls are provided, which secure the closing element against a backward displacement, which would relieve the sealing device again.
  • a corresponding pawl is comparatively easy to implement in the region of the displaceable closing element, since an electric motor which drives the closing element can also be used to move the pawl back.
  • Corresponding pawls to set the arranged on the movable and locked vehicle part rotary latch although known, but require in previously known locking devices a separate and therefore expensive drive the pawl.
  • a locking device is arranged on a lock of the locking device, by means of which the catch can be locked, but the pawl lever for opening the locking device not by a separate drive, but on the movement of the closing element, which for Opening the locking device is also necessary, is rotated to release the catch.
  • a pawl lever is arranged on a lock of the locking device, by means of which the catch can be locked, but the pawl lever for opening the locking device not by a separate drive, but on the movement of the closing element, which for Opening the locking device is also necessary, is rotated to release the catch.
  • the pawl lever by means of which the catch can be locked, is biased by a spring element in a locking direction of rotation in the closing direction of rotation of the rotary latch to this.
  • Fig. 1 shows a schematic view of a closed in a closing direction
  • a locking device according to the present invention with a lock 10, which has a rotary latch 18 which is mounted on a rotation axis 26a.
  • the rotary latch 18 has a nose 20, by means of which it can engage by rotation in a closed direction of rotation B counterclockwise in the opening of a closure member 12 designed as a closing element.
  • the rotary latch 18 is locked by a pawl lever 22 in its closed position, wherein the pawl lever is also rotatably supported via a rotation axis 26b and is biased by a spring element, not shown, clockwise.
  • the rotary latch 18 in turn is also loaded by means of a spring element, not shown, in the clockwise direction (ie counter to the closing direction B), and is rotated when closing the locking device by the striker 12 against the bias of the spring element counterclockwise (in the closing direction B) so that she comes into engagement with the striker.
  • the striker 12 is displaceably mounted on a second plate 16 relative to a first body-mounted plate 14 and may be displaced by a displacement of the second plate in the closing direction A and back (down or up in the image direction). This is achieved in that the second plate 16 is displaceable on the first plate 14 along an axis in the image direction up and down.
  • the displacement is controlled by a functional disk 32, which has a cam 28 which projects into a recess 30 of the second plate 16.
  • a rotation of the functional disk 32 for example by means of an electric motor, the cam 28 engages with a lower edge of the recess 30 so that the second plate 16 can be displaced relative to the first plate 14.
  • the second plate 16 is guided for displacement on two lateral guides 34, which are mounted on the first plate 14.
  • the function disk 32 was rotated clockwise so that starting from the position of the Fig. 1 the cam 28 has passed through a bottom dead center in a clockwise direction below the axis of rotation 26c relative to the rotational axis 26c of the functional disk and is now still in engagement with the lower edge of the recess 30 on a side opposite the axis of rotation 26c.
  • the angle of rotation of the functional disk 32 was chosen so that the cam 28 according to the Fig. 2 in image direction upwards a little higher to lying, than in the Fig.
  • the Fig. 5 to 7 show a subsequent closing process (in the closing direction A) of the locking device.
  • the rotary latch 18 has already been rotated by the striker 12 counterclockwise so far that the catch 18 is again in engagement with the striker 12. It is a first closed position reached in which also the voltage applied to the catch 18 pawl lever 22 has again rotated counterclockwise by snapping into a stop 23b of the catch so that it locks the catch 18 and an unwanted opening of the lock 10, for example Shaking the vehicle is prevented.
  • the pawl lever 22 slides along a circular arc-shaped edge 23a of the rotary latch with the circle center in the axis of rotation 26a until it engages in the stop 23b.
  • the locking device not only surcharge hammer 38a on which the lock already in the first closed position ( Fig. 5 ), as well as in the second closed position ( Fig. 7 ), but also further supplemental damper 38b, where the lock normally only in the second closed position of Fig. 7 respectively.
  • Fig. 1 comes to the concern. While the contact surfaces between the first supplemental dampers 38a and the lock 10 are arranged substantially perpendicular to the closing direction of the locking device, the aggregate dampers 38b contact surfaces for lock 10, which are oriented obliquely to the closing direction of the locking device.
  • the additional aggregate dampers 38b are also provided to dampen the lock in the event of a violent slamming of the locking device and to center by the oblique orientation of the contact surfaces in the direction of striker 12.
  • FIG. 8 shows the striker 12 with the plates 14 and 16 and the release cam 24 again in a perspective view without lock.
  • FIGS. 9 and 10 is schematically illustrated the attachment of the locking device according to the invention.
  • the lock 10 by means of a mounting plate 44 on a movable and locking vehicle part, such as a vehicle door or a trunk lid or even a cover for a hinged vehicle roof fastened.
  • the first plate 14, which carries the second plate 16 together with the striker 12, fastened to the vehicle body on a vehicle the plate 14 carries a housing 48 which can receive a drive for the functional disk 32.
  • a drive may for example be an electric motor which can be connected by means of a connection 50 with the vehicle electronics.
  • a sensor such as a Hall sensor so relative to the rotary latch 18 may be arranged so that it can emit a signal to the vehicle electronics, which indicates the state of the rotary latch 18 (open or closed) the electronics can pass, the signal for controlling the functional disk 32 driving electric motor can be used.
  • Fig. 11 shows a detailed view of the locking device, in particular, the release lever 42 is shown enlarged.
  • the release lever 42 is rotatably mounted on a rotation axis 26d on the first plate 14, wherein the plate 14 has a recess in the form of a groove or link 54 which limits the Verschwenkungs Scheme of the release cam 24.
  • the release cam 24 can be designed so that it not only protrudes upward in the image direction from the release lever 42, but also continued in the image direction so that it engages in the slot 54 of the plate 14 and is guided through the backdrop, to set the maximum pivoting range of the release lever 42.
  • a spring element 52 causes a bias of the release lever in the direction of the rotary latch 18, so that it is ensured that it rests in the first and second closed position of the locking device on the extension 25 of the pawl lever 22.
  • the axes of rotation, directions of rotation and the biasing directions can also be oriented mirror-inverted relative to the striker 12.
