Definitions
- the invention relates to a door lock with a motor-driven Opening aid, especially for doors, flaps or hoods of motor vehicles, with a lock latch between one Releasing locking pin and a locking position pivotable is a pawl, which locks the lock latch between Closed position and a position releasing the lock latch is movable, and a motor-driven, rotating around an axis Driver cam, which the pawl in its the lock latch releasing position, and by a movable stop can be blocked, the driver cam when locking the door lock releases, the driver cam from the engagement area of the Pawl and / or the stop is movable.
- 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 present invention is a door lock to create a simpler constructive Adaptation to the required opening forces and the existing one Space allowed.
- the object is achieved by a door lock as described in the introduction Type solved, in which the driver cam with reference to the axis of rotation between an inner radial position in which it is is outside the engagement area of the pawl and the stop, and an outer radial position in which it is movable in the engagement area the pawl and the stop.
- the lower actuation forces allow smaller drives and use of plastic parts, for example for the driving cams, whereby the opening noises can be reduced.
- the lower ones mechanical loads may also allow temporal loads Shortening the opening cycle.
- the control of the movement of the driver cam can either be mechanical positively controlled in both directions, preferably however, the driver cam moves into its radial outer position against the action of a preloaded spring, which the for returning the driver cam to its radial inner position stores necessary energy.
- At least a fixed guide link is provided on which the driver cam with the drive switched on against its tensioning spring slides radially outwards.
- the driver cam is preferably arranged on a driver lever, on a drive element rotating around the circumferential axis is pivotally mounted.
- the swiveling driver lever takes over Guiding the trajectory of the driver cam between its two radial positions.
- the separate opening lever allows driver cams to be freely selected the gear ratio, which makes the driving forces optimal can be tuned to the necessary opening forces, whereby a further noise reduction is possible.
- the separate arrangement allows also greater scope in the spatial arrangement of the individual Lever.
- the release of the driver cam when the door lock is closed can be realized, for example, that the block lever by the pawl or the opening lever when closing the lock latch is pivotable, being an alternative to that from the orbit of the Driving cam pivoting stop also a targeted return of the driver cam in its radial inner position is conceivable. With such a configuration, the stop could be made stationary his.
- the spring arrangement is designed bistable so that the driver cam is blocked in its radial outer position, with the help of unlocking means is traceable to its radial inner position.
- a manually operated opening device the Basically provided for all door locks with a motorized opening aid is and acts on the pawl, also on such unlocking means act and thus ensure that the driver cam from the engagement area of the stop or the pawl or the Opening lever moves.
- the block hoist or the pawl or the opening lever when closing the Lock latch the blockage of the cam in its radial outer position for example by acting on the unlocking means.
- the driver cam at bistable trained spring arrangement in normal operation always in its radial Outside position persists and only in its case of an emergency opening radial inner layer is returned, however, during each Repeatedly brought about the operational safety at spatial increase tight arrangement.
- the geometry of the Contact surfaces of the driver cam on the pawl or the opening lever and the stop should be chosen so that the driver cam in contact with the driving forces in its radial outer position persists.
- the driver cam returns automatically returns to its inner radial position when the drive motor is switched off and / or the block lever or the pawl or the Opening lever from the movement path of the driver cam pivots.
- FIG. 1 is a schematic view of a door lock 10 in the shown closed rest position.
- the door lock 10 has the usual Way via a lock latch 12 which is between a closed Closed position and a releasing a locking pin, not shown open position is pivotable.
- One also swiveling stored pawl 14 locks in a conventional manner Rotary latch 12 with the aid of a catch 16 in its closed position, between the lock latch 12 and the locking blade 14 a tension spring 18 is arranged , which strives to close the rotary latch 12 in its open position swivel.
- the door lock 10 also has a motor-driven Opening aid 20, with the help of which the pawl 14 in a Lock latch 12 unlocking position is movable.
- the opening aid 20 has a driven by an electric motor (not shown) Drive element 22, on which a driver lever 24 with a driver cam 26 is pivotally mounted eccentrically. Between the Drive element 22 and the driver lever 24 is a spring 28, the latter biased towards a rest position in which the Driver cams 26 in a with respect to the axis of rotation 30 of the drive element 22 is located radially inner position. There is also an opening lever 32 provided, as well as a block lever 34 around a common axis 36 is pivotally mounted. The opening lever 32 has a contact surface 38, which will be described later Interacts with the drive cam 26, and a driver surface 40 which cooperates with a lever arm 42 of the pawl. There is also a lever shoulder 44 on the opening lever 32 provided on which an emergency opening device, not shown attacks.
- the block lever 34 has an operating lever 46, which with the Opening lever 32 cooperates, and a stop 48, the one another lever arm is arranged.
- a microswitch 50 acts with an extension 52 on the lever arm 42 Pawl 14 together and is capable of the closed position the lock latch 12 to capture.
- the lock latch 12 is already unlocked at this time, however
- the drive motor of the opening aid 20 initially continues to run.
- the driver cam 26 is under again Biasing the spring 28 in a radially outer position with respect the axis of rotation 30 moves, engaging the stop 48 arrives at the block lever 34 pivoted into its movement path. In this position, the electric motor is blocked, with a shutdown by monitoring the current consumption on the basis of this Moment of greatly increasing current takes place.
- This open state with blocked driver cam 26 is shown in Fig. 5.
- the lock latch 12 is closed by inserting the locking pin Moved position, the pawl 14 snaps into their Lock latch 12 locking position back, the operating lever 46 of the block lever releases, so that the stop 48 under the load of Spring 28 is pushed outward, thereby releasing the driver cam 26 takes place.
- this can return to its radially inner Snap back position so that again the closed shown in Fig. 1 Rest position of the door lock 10 results.
- a failure of the drive motor is not critical under any circumstances, because by actuating the emergency opening aid via the lever shoulder 44, for example also in the position of the driver cams shown in FIG. 4 26 can be released so that it snap back into its radially inner position can. Since he is in this position regardless of the rotational position outside the engagement area of the stop 48 and the contact surface 38 is a hindrance to manual opening or Closing the door lock 10 excluded.
- FIG. 6 to 11 show a further embodiment of a door lock 100, which in turn has a lock latch 102 and a pawl 104, which interact via a catch 106 and between which one Tension spring 108 is provided.
- An opening aid 110 is also provided here, the one from an electric motor (not shown) via a Worm gear (also not shown) driven drive element 112, on which a driver lever 114 with a driver cam 116 is pivotally mounted eccentrically. This gives there is in turn a pivotability of the driving cam 116 between one radial with respect to the axis of rotation 118 of the drive element 112 further inward and a radially further outward position.
- the arrangement is different from the variant described above the spring 119 (see Fig.
- the driver lever 114 is bistable, i.e. that it is also in its radial outer position remains without interacting with the stop surfaces to be instructed.
- the spring arrangement is chosen so that a Dead center of the driving lever 114 in the vicinity of the radial outer position of the driving cam 116 results, so that a pivoting of the Driver lever 114 is sufficient for a very short distance, this in his to snap back radially inner layer.
- the driver lever has a first actuating cam 120 and a second actuation cam located further inside 122.
- a lever arm 124 of the pawl 104 up into the orbit of the driving cam 116 in its radially outer position, so that no additional Opening lever is necessary. Also a lever shoulder 126, on which an emergency release device attacks, is directly on the Pawl 104 is provided.
- the pawl 104 also has an unlocking lever 128, the function of which will be discussed later becomes.
- the lever arm 124 of the pawl also acts directly with an actuating lever 130 of a block lever 132 together, which is pivotally mounted is and has a stop 134 which is in the orbit of the driving cam 116 located in its radial outer position can be pivoted in is.
- the drive of the opening aid 110 starts Drive element 112 in the counterclockwise direction in the sense of the illustration rotate.
- the driver cam 116 remains in its radial outer position, too after he has passed the guide backdrop 136.
- the locking pin in turn reaches the engagement area of the lock latch 102, this is turned back into its closed position, whereupon the Pawl 104 snaps back and the lock latch 102 over the catch 106 locked.
- the driver cam 116 remains in its radial outer position and at a restart of the electric drive the block lever 132 pivoted by pushing the stop 134 aside.
- An emergency opening of the door lock if the opening aid fails 110 is possible with the help of the unlocking lever 128, which is actuated the pawl 104 via the emergency opening aid on the second actuation cam 122 acts and thereby snaps back the driver cam 116 in its radially inner position (see FIG. 11), in which of these is outside the engagement area of the lever arm 124 and of the stop 134 is located so that a hindrance to a manual opening or closing process is excluded.
- the opening aid is immediately ready for operation again
- To be able to move is a fixed in the area of the stop 134 second guide link 138 is provided which the driver cam immediately after an emergency opening in its radial outside position moves so that it can run against the stop 134. Normally however, there is no interaction between the second management backdrop 138 and the driving lever 114.
- Modifications of the previously described exemplary embodiments can consist, for example, in a bistable spring arrangement 6 to 11, an additional opening lever corresponding to that in Fig. 1 to 5 shown door lock is used or a door lock 1 to 5 with a pawl similar to the door lock 100 according to 6 to 11 is designed without an opening lever.
- Driving element created driving element are also other guides of the driver cam to achieve the desired radial movement conceivable, for example linear guides on the drive element.
