Definitions
- the invention is directed to a rotary latch lock in the preamble of Claim 1 specified type.
- the rotary latch takes in its one rotary end position, namely its closed position, a closing member, said closed position of a spring-loaded pivoting latch is locked. Then there is the latch in their locked position. If the latch is unlocked, the catch is released and by a restoring force in their other rotational end position, namely an open position transferred. Then that closing member is free. In this open position of the rotary latch is located the pawl in a standby position, where it is supported on the rotary latch.
- the pawl In the case of a reverse rotation of the catch by the closing member the pawl passes back into its closed position or in a Vorrastlage what the blocking position or Pre-locking position corresponds to the catch.
- To unlock the latch is a motor used to charge an energy storage. The engine becomes effective if - in the case of a user's access authorization - for example, a Rotary latch lock belonging handle is pressed.
- the disadvantage of the known rotary latch lock is in the relatively high energy consumption for the operation of the engine.
- the engine does not just have to Energy to unlock the latch and adjust the associated He must also load the energy storage, so that this has sufficient energy after switching off the engine to the Control the pawl serving driver back into the aforementioned Due to the starting position.
- it comes in a crash to deformations of Lock components used to unlock the pawl in its locked position require a higher energy compared to the normal case. Otherwise that would be Rotary latch lock motor no longer operable and the occupants in the vehicle captured.
- the well-known rotary latch requires therefore strong engines, the not only expensive, but also space-wasting. That's because of the limited space in the area of a rotary latch lock disturbing.
- rotary latch lock specified in the preamble type (DE 195 05 779 A1) is the pawl except with an actuating surface with a Stop surface provided for a rotationally driven by the engine control cam. through a spring, the cam is biased in the direction of rotation of the motor.
- the Rotary latch releasing standby position is the cam on the stop surface of Latch on, wherein the spring loading it is tensioned. Because of this stop will be the engine is switched off.
- this is Stop surface outside the trajectory of the cam, which is why this, then Effect of the spring is transferred back to a starting position opposite the stop position is offset by an angular amount.
- the invention is based on the object, a reliable working Rotary latch lock to develop the mentioned in the preamble of claim 1 way that works with a low energy engine and also in the Crash case remains functional. This is inventively by the im Characteristics of claim 1 listed measures achieved, the following particular importance.
- the energy consumption of the engine for charging the energy storage on the one hand and for unlocking the latch on the other hand, in the invention is not additive, in applied the same phase of operation, but takes place successively in two different operating phases.
- To unlock the latch is first in the used charged energy store stored energy storage. Normally that is enough Unloading the energy accumulator for adjusting the pawl.
- the invention thus two various sources of energy available, namely on the one hand by the charged energy storage released energy and on the other hand by the Engine applied in the current operating phase engine energy. Because of these Selective operation of the engine can now one on low Use energy level working engine. Such engines are cheap and space-saving.
- the rotary latch comprises a bolt-shaped closure member 10, the stationary fixed to a stationary door handle of a motor vehicle body and in the figures for clarity in hatching is highlighted.
- the others Components of the rotary latch lock are in a housing 11 of a movable Motor vehicle door arranged, to which in particular a rotary latch 20 belongs.
- the Rotary latch 20 is rotatable between two Drehendlagen, of which one in FIG. 1 and the other in Fig. 6 is shown. In between there is a row another important intermediate layers, which are shown in Figs. 2 to 4.
- the Rotary latch sits on an axle 21 and is under the action of a burden Restoring force, which can come about in various ways and in the Figures by a force arrow 22 is illustrated.
- the restoring force 22 is endeavoring to transfer the rotary latch 20 into its rotary end position shown in FIG. 6, where it is held by a stop 12 in a defined position.
- the rotary latch 20 has a profiled radial outbreak 23, in which, at Closing the motor vehicle door in the sense of the indicated in Fig. 6 Scht manterrorisms arrow 13, the closing member 10 retracts and the case 20 in the in Fig. 1 shown a Drehendlage moves. Then the motor vehicle door closed, which is why the position shown in Fig. 1 of the rotary latch 20 is to be called "closed position". Is the catch 20 in the other Drehendlage, the dash-dotted lines in Fig. 4 already illustrated is, then the closure member 10 is released, and it is a relative movement of the closing member 10 relative to the door in the sense of that shown in FIG. 4 Movement arrow 13 'possible. Then the closing member is free and can be off the position 10 in the radial outbreak 23 of the rotary latch 20 in its release position 10 'are transferred. This proves that in Fig. 5 or 6 shown Drehend ein the rotary latch 20 as "open position".
- a here two-armed 31, 32 trained Pawl 30, which is provided on an axis 11 provided in the housing 34 is arranged pivotally.
- the one arm 31 of the pawl 30 cooperates with the catch 20 together and is therefore to be called a "working arm”, while the other arm 32 for controlling various adjustment movements the pawl 30 is used and therefore hereinafter referred to as "actuator arm” shall be.
- the pawl 30 is, as shown by the force arrow 33 of FIG. 1, spring loaded and therefore endeavors, with her working arm 31 compliant to be moved against the rotary latch 20.
- the pawl-working arm 31 engages in a first flank 24 of the rotary latch 20 and holds them so against their restoring force 22 firmly.
- the latch 30 So is in Fig. 1 in its locking effective position, which is why this should be referred to below as "blocking position”.
- This flank 24 is characterized by a suitable profiling of the aforementioned Radial outbreak 23 formed for the closing member 10.
- a similar retention effect results in the illustrated embodiment, then, if in a z. B. from Fig. 3 apparent intermediate position of the catch the pawl 30, contrary to the local representation, would be free and therefore with her working arm 31 in a further recessed edge 25 of the Trap 20 would retract, which illustrates dotted in Fig. 3 is. Even then, the closing member 10 would still be in the radial outbreak 23rd caught the catch 20. Then the catch 20 would be in one "Vorrastlage" are located. This proves the previously described Flank 24, which in the full closed position of the rotary latch 20 of FIG. 1 is effective is, as a "main-back flank". It is understood that other liners the catch by corresponding additional flanks in the catch 20 could be determined, in which the pawl working arm 31 respectively locks effective to the respective rotational position of the case 20 to to back up.
- a DC motor 50 is arranged, the via a gear 52, 53 for the rotary drive of a control cam 51st serves.
- a screw 52 which engages in a worm wheel 53.
- the engine 50 is over its two in the schematic diagram of Fig. 10 with 54, 55 marked lines via a central plug 14 with a not shown in detail Control logic in conjunction, their mode of action based on the control program 11 will be explained in more detail.
- These components are sensors 15, 16, in the present Case consist of microswitches. Because of a sensor 15 with the trap 20 cooperates, it should be called hereinafter briefly "case sensor”, while the other sensor 16, because he has to be described in more detail Lever 40 cooperates, analogously referred to as a "lever sensor” shall be.
- the lever 40 is disposed on the same axis 34 as the pawl 30 and is under the action of an energy storage 60.
- the energy storage 60 performs a storage force illustrated in the direction of the arrow 61 of FIG on the lever 40, which is why this briefly below "memory lever" should be designated.
- the energy storage 60 is in the illustrated embodiment designed as a compression spring whose one end of the spring is fixed 62 is supported in the housing 11 and the other end of the spring on the storage lever 40 works. In the closed position of the rotary latch of Fig. 1 is based the storage lever 40 on the control cam 51 from, which is why the him acting force 61 of the charged force accumulator 60 does not discharge can.
- the storage lever 40 is in its pivoting end position maximum charged energy storage 60.
- the handle can mechanically, or, as said to be electronically effective. Then there is an operation the handle successful and sets, as explained in more detail with reference to FIG. 11 to be, the first resting motor 50 in his by the movement arrow 56 illustrated forward drive.
- Fig. 10 shows in the electrical Control with five pins made by the aforementioned lines 54, 55 and 17 to 19 are represented.
- Fig. 11 shows in time dependence the electrical controls of four of these pins 54, 55, 17, 19 along the timeline t marked there.
- the fifth pin is 18 in the control program of FIG. 11, because it, like FIG. 10 shows, constantly under a negative voltage.
- the topmost curve 45 is the control cam of the handle. The operation of the handle acts on the control logic.
- the handle should be operated, including it comes to an apparent from the curve 45 pulse 46 whose Length depends on the duration of operation.
- the control logic speaks t0 on the triggered by the handle pulse start and sets the Pin 54, which until then on, as indicated in Fig. 11, to negative Potential was at the time t1 to a positive potential.
- the time difference between t0 and t1 is only a few microseconds. This reaction between the handle according to control cam 45 via the control logic the pin 54 is illustrated in FIG. 11 by an action arrow 47.
- This output rotational position of the worm wheel 53 may also determined by a stationary rotation stop 58 in the lock housing 11 against which a provided on the worm wheel 53 radial finger 59 can trigger.
- This stop action at 58, 59 is not mandatory required; It could normally be a gap here, the Noise in the control movements of the components avoids.
- Fig. 11 shows, namely, in the period before t0, the two pins 54, 55 of Motors at the same negative level; the electrical wires of the Motors are shorted, which is why the engine stops.
- the pivoting movement 43 of the storage lever 40 comes by unloading of the energy storage 60, while the control cam 51 this Pivoting movement 43 only "braking" at its forward drive 56 controls. As illustrated in FIG. 2, in this pivotal movement 43, finally the actuator of the lever sensor 16 is released, which in Fig. 11 for Time t2 should happen.
- the hitherto on positive potential Pin 17 of the circuit in FIG. 10 reaches the negative level of the pin 18, which initially has no further effects.
- the rotary latch 20 has under the effect of its restoring force 22 so far twisted that the actuator of the case sensor 15 of the associated Control profile 26 is released.
- the closed in Fig. 10 contact of the case sensor 16 sets the pin 19 to the negative potential of Pins 18, which corresponds to the time t3 in the control program of FIG. 11.
- the latch 30 is in Fig. 4 by the storage power 61 already in their Schwenkend ein passes, which is why the pawl 30 and the storage lever 40 from there on rest first.
- the control cam 51 is up to the time t3 has been further rotated in the direction of arrow 56 and thereby has the memory lever 40 left.
- the belonging to the rotary latch lock control logic speaks to the reversal of the case sensor 15 at time t3 of Fig. 11 and sets the two to the motor 50 belonging pins 54, 55 after a short reaction time, namely at time t4 of Fig. 11, on mirror image potential. This is through the double action arrows 48 in Fig. 11 illustrated.
- the pin 54 becomes switched to negative and pin 55 to positive potential. This causes, that the hitherto rotationally driven motor 50 due to the reverse voltage slows down first. This is intended in the rotational position shown in Fig. 4 of the control cam 51 can be reached. But then it turns Rotation of the motor, so that it by the rotation arrow 56 'in Figs. 4 and 5 apparent reverse drive of the motor and thus the control cam 51 is coming.
- the catch 20 is due the restoring force acting on them 22 in their full, dash-dotted lines in Fig. 4 clarified revealed that allows the motor vehicle door to open.
- the closing member 10 can its radial outbreak 23 in the Leave catch 20; it comes to that by the arrow 13 'in Fig. 4th illustrated opening movement, which the closing member in its release position 10 'can get.
- Fig. 6 shows such a final state with the door open.
- the energy storage 60 is fully charged again.
- the storage lever 40 While the storage lever 40 is in its starting position is located, which is also present with the door closed, is the latch 30 in their described ready position, as long as the closing member in its release position 10 'outside of the rotary latch 20 is located. If accidentally with the door open the handle can be pressed again should, the control logic provides for idling the motor 50. That will namely recognized by the control logic that the case sensor 15 to the case 20 remains unconfirmed.
- the force acting on the pawl 30 spring force 33 are achieved by a spring member 27, which between the pawl 30 and the storage lever 40 is effective.
- the pawl 32 could be described by its own spring Spring force 33 obtained.
- the acting on the storage lever 40 Force accumulator 60 is indicated only schematically in the drawings; concrete it could consist of a two-legged spring, one end of the spring is supported on the housing and the other end of the storage power 61st exercises.
- Fig. 7 shows a rotational position of the rotary latch, the corresponds to the conditions described in Fig. 2 in the normal case.
- the pivoting movement 36 from Pawl 32 is sluggish, which z. B. by a preceding Crash of the motor vehicle may have resulted.
- Fig. 8 is just reached a limit situation where the control cam 51 due to its further movement 56 on the inner edge of the pawl actuating arm 32 provided control profile 39 has reached and along it moved, as can be seen from Fig. 9.
- the control cam 51 exerts an additional, apparent from Fig. 8 opening force 63 in addition to the over the point of contact 35 from Memory lever 40 applied storage power 61 added.
- the pawl working arm 31 has the hitherto initially dot-dashed clarified position of the catch left and under the effect of their restoring force 22 in their undressed drawn open position arrives.
- the closure member is in its release position 10 'convertible.
- FIG. 9 describes relationships analogous to those of FIG. 4 described normal case.
- This angle 64 corresponds to a correspondingly larger Energy consumption, applied by the engine 50 in a special case and the Opening the stiff rotary latch 20 has been used.
- a comparison between Fig. 4 and 9 shows that in the special case of Fig. 9 and the energy storage 60 has discharged much more and therefore also here additional energy to open the catch 20 by the storage power 61 has been applied. All this is possible with economical energy exploitation on the engine 50; The engine can be weak and therefore space-saving be educated.

dass - ausgehend von der Ausgangsposition - beim Vorwärtstrieb (56) des Motors (50) der Steuernocken (51) so bewegt wird, dass durch Entladen des Kraftspeichers (60) der Speicherhebel (40) sich auf die Klinke (30) zu bewegen kann und wenigstens in der Endphase seiner Bewegung die Speicherkraft (61) des Kraftspeichers (60) auf die Klinke (30) überträgt,
dass im Normalfall die Speicherkraft (61) des Kraftspeichers (60) ausreicht, um die Klinke (30) in ihre die Drehfalle (20) freigebende Stellung zu bewegen, aber in einem Sonderfall, wo das nicht genügt, der Steuernocken (51) die speicherhebelseitig veranlasste Bewegung der Klinke (30) unterstützt,
und dass der Motor (50) in einen den Kraftspeicher wieder aufladenden Rückwärtstrieb (56') antreibbar ist, wo der Steuernocken (51) gegen den Speicherhebel (40) fährt und diesen in die Ausgangsposition zurückführt. - Drehfallenschloss nach Anspruch 1, dadurch gekennzeichnet, dass der Steuernocken (51) beim Vorwärts- und Rückwärtstrieb des Motors (50) in einem Abstandsraum (44) zwischen dem Speicherhebel (40) einerseits und einem Stellarm (32) der Klinke andererseits hin- und hergedreht (56, 56') wird.
- Drehfallenschloss nach Anspruch 1 oder 2, dadurch gekennzeichnet, dass der Speicherhebel (40) und die Klinke (30) zwar auf einer gemeinsamen Achse im Schlossgehäuse (11) schwenkgelagert sind, aber im Betriebsfall wenigstens phasenweise getrennt schwenkbeweglich (36; 43; 43') sind.
- Drehfallenschloss nach einem der Ansprüche 1 bis 3, dadurch gekennzeichnet, dass die Federbelastung (33) der Klinke (30) zugleich auf den Speicherhebel (40) wirkt und die Klinke (30) sowie Speicherhebel (40) im Gegeneinanderbewegungssinne zueinander treibt.
- Drehfallenschloss nach einem der Ansprüche 1 bis 4, dadurch gekennzeichnet, dass ein Fallensensor (15) die Drehlage der Drehfalle (20) überwacht und dann (t1) anspricht,
wenn die Drehfalle (20) aus ihrer Schließlage sich soweit weiterbewegt hat, dass sie von der Klinke (30) nicht mehr an einer Weiterdrehung (22) in ihre Offenlage gehindert werden kann,
wobei dieser Fallensensor (15) im Ansprechfall auf die Steuerlogik einwirkt, um den Motor (50) in den Vorwärtstrieb (56) zu schalten. - Drehfallenschloss nach einem der Ansprüche 1 bis 5, dadurch gekennzeichnet, dass ein Hebelsensor (16) die Position des Speicherhebels bzw. des Steuernockens überwacht und dann (t4) anspricht,
wenn der vom Rückwärtstrieb (56') des Motors (50) bewegte Steuernocken (51) in seine die Bereitschaftsposition der Klinke (30) entsprechenden Ausgangsposition gelangt ist,
wobei der Hebelsensor (16) im Ansprechfall auf der Steuerlogik einwirkt, um den Rückwärtstrieb (56') des Motors (50) zu stoppen. - Drehfallenschloss nach einem der Ansprüche 1 bis 6, dadurch gekennzeichnet, dass die beiden Endpositionen des Motors (50) bzw. seines Getriebes (52, 53) zusätzlich durch Drehendanschläge (58, 38) begrenzt sind.
