Definitions
- the invention is directed to a rotary latch lock of the type specified in the preamble of claim 1.
- the rotary latch takes up a locking member in its one rotary end position, namely its closed position, this closed position being held by a spring-loaded, pivotable latch. Then the pawl is in its locked position. If the pawl is transferred to a release position releasing the catch, the catch can be transferred into its other rotational end position, namely an open position, by a restoring force, where it releases the locking member.
- the spring-loaded pawl In this open position, the spring-loaded pawl is transferred to a standby position, where it is supported on the rotary latch located in its open position and is ready, in the event of a return rotation of the rotary latch to its closed position or a preceding pre-latched position to its locked position or pre-latched position to the rotary latch reach.
- a motor and an energy accumulator are used to adjust the pawl. The motor becomes effective if - in the case of user access authorization - a handle belonging to the rotary latch lock is actuated.
- the motor only serves to transfer the pawl from its locking position holding the rotary latch into a release position releasing the rotary latch, during the transition of the pawl into a standby position prepared for the future locking position from an energy store is effected, which serves as a return spring for the return of a driver serving to adjust the pawl.
- the energy accumulator is discharged in the known lock and leads the driver back into a starting position which characterizes the locked position of the rotary latch back, while the latch initially remains in its standby position with respect to the rotary latch which is still in the open position.
- the disadvantage of the known rotary latch lock is the relatively high energy expenditure for operating the motor.
- the motor must not only use energy to adjust the pawl and the associated working elements in order to transfer them from the locked position into a release position, but it must also charge the energy accumulator so that it has sufficient energy after the engine has been switched off to be able to Control of the pawl serving driver back to the starting position.
- the known rotary latch lock is used in a motor vehicle, the lock components are deformed in the event of a crash, which requires higher energy to move the pawl from the locked position into its release position, otherwise the rotary latch lock would no longer be operable by a motor and the occupants would be caught in the motor vehicle.
- the well-known rotary latch lock requires powerful motors that are not only expensive but also wasteful of space. This is annoying because of the limited space in the area of a rotary latch lock.
- the invention has for its object to develop a reliably working rotary latch lock of the type mentioned in the preamble of claim 1, which works with a motor operating at a low energy level and remains functional even in the event of a crash. This is achieved according to the invention by the measures specified in the characterizing part of claim 1, which have the following special significance.
- the invention first relocates the charging of the energy accumulator by the motor to a different time phase than the adjustment movement for reversing the pawl from its locked position into a release position with respect to the rotary latch.
- the pawl is reversed while the motor is driving forward, while the energy accumulator is charged by a motor reverse drive.
- the energy expenditure for these two measures therefore does not run additively, but separately, which allows the use of engines operating at a lower energy level.
- Such motors are inexpensive and save space.
- the energy accumulator acts on a special pivotable lever, which when Loading the energy accumulator is transferred by a control cam when the motor is driven backwards into an initial position which corresponds to the ready position of the pawl.
- this lever will hereinafter be referred to as "accumulator lever" for short.
- the control cam only acts as a brake when the motor moves forward in the initial phase of the pivoting movement of the storage lever before the storage lever hits an actuating arm belonging to the pawl and thereby uses the energy released when the energy accumulator is unloaded to adjust the pawl.
- the z. B. can result in a crash, the control cam moves against an actuator provided on the pawl and supports the actuating movement of the pawl from its locked position to its release position.
- FIG. 1 is a top view of the latch lock according to the invention when the pawl is in a locked position and holds the catch in its closed position
- FIGS. 8 and 9 show two further working positions of the components in the special case of FIG. 7, FIG. 9 showing the positions and positions of the pawl and the case of normal operation shown in FIGS. 4 and 5 for this special case,
- FIGS. 1 to 9 schematically shows a circuit diagram of some of the electrical components of the lock shown in FIGS. 1 to 9, and
- FIG. 11 shows a control diagram of the electrical circuit shown in FIG. 10, from which the course of the voltages over time and their relationships are illustrated by means of a switching logic.
- the rotary latch lock comprises a locking member 10, which is bolt-shaped here and is fixed in place on a stationary door spar of a motor vehicle body and is highlighted in hatching in the figures for clarification.
- the other components of the rotary latch lock are arranged in a housing 11 of a movable motor vehicle door, which in particular includes a rotary latch 20.
- the rotary latch 20 can be rotated between two rotary end positions, one of which is shown in FIG. 1 and the other in FIG. 6. In between there are a number of other important intermediate layers, which are shown in FIGS. 2 to 4.
- the rotary latch is seated on an axis 21 and is under the action of a restoring force loading it, which can come about in various ways and is illustrated in the figures by a force arrow 22.
- the restoring force 22 endeavors to transfer the rotary latch 20 into its rotational end position shown in FIG. 6, where it is held in a defined position by a stop 12.
- the rotary latch 20 has a profiled radial cutout 23 into which, when the motor vehicle door is closed in the sense of the closing movement arrow 13 indicated in FIG. 6, the closing member 10 retracts and the latch 20 moves into the rotary end position shown in FIG. 1. Then the force Vehicle door closed, which is why the position of the rotary latch 20 shown in FIG. 1 is to be referred to as the "closed position". If the rotary latch 20 is in the other rotational end position, which is also already shown in dash-dot lines in FIG. 4, the closing member 10 is released and a relative movement of the closing member 10 with respect to the door is possible in the sense of the movement arrow 13 'shown in FIG. 4 .
- Another component of the lock is a two-arm 31, 32 designed pawl 30 which is pivotally arranged on an axis 34 provided in the housing 11.
- One arm 31 of the pawl 30 interacts with the rotary latch 20 and is therefore to be referred to as a "working arm”, while the other arm 32 is used to control various adjustment movements of the pawl 30 and is therefore to be referred to below as an "actuating arm”.
- the pawl 30 is, as shown by the force arrow 33 of FIG. 1, spring-loaded and therefore endeavors to be flexibly moved with its working arm 31 against the rotary latch 20. In the closed position of FIG. 1, the pawl working arm 31 engages in a first flank 24 of the rotary latch 20 and thus holds it against its restoring force 22. The pawl 30 is therefore in its locking position in FIG. 1, which is why it will be referred to in the following for short as the "locking position”.
- This flank 24 is formed by a suitable profiling of the aforementioned radial cutout 23 for the closing member 10.
- a similar retention effect results in the illustrated embodiment even if in a z. B. apparent from Fig. 3 intermediate position of the catch, the pawl 30, contrary to the representation there, would be free and would therefore drive with its working arm 31 into a further recessed flank 25 of the catch 20, which is illustrated in FIG. 3 dotted. Even then, the closing member 10 would still be caught in the radial cutout 23 of the rotary latch 20. Then the rotary latch 20 would be in a "pre-latched position".
- a DC motor 50 is also arranged in the lock housing 11 and is used for the rotary drive of a control cam 51 via a gear 52, 53.
- a worm 52 sits on the motor shaft and engages in a worm wheel 53.
- the motor 50 is connected via its two lines marked 54, 55 in the schematic circuit diagram of FIG. 10 via a central plug 14 to a control logic, not shown in more detail, the mode of operation of which will be explained in more detail with reference to the control program of FIG. 11.
- latch sensor Because one sensor 15 interacts with the latch 20, it is to be called “latch sensor” in the following, while the other sensor 16, because it cooperates with a lever 40 to be described in more detail, is to be referred to in an analogous manner as a "lever sensor”.
- the lever 40 is arranged on the same axis 34 as the pawl 30 and is under the action of an energy accumulator 60.
- the energy accumulator 60 exerts a storage force, illustrated in the direction of the arrow 61 in FIG. 1, on the lever 40, which is why it is briefly described below as “ Storage lever "should be referred to.
- the energy accumulator 60 is designed as a compression spring, one spring end of which is supported in a stationary manner in the housing 11 and the other spring end of which acts on the storage lever 40.
- the storage lever 40 In the closed position of the rotary latch of FIG. 1, the storage lever 40 is supported on the control cam 51, which is why the force 61 of the loaded energy accumulator 60 acting on it cannot be discharged.
- the storage lever 40 is in its swivel end position when the energy accumulator 60 is loaded to the maximum.
- the door shown handle can be actuated, which can be done mechanically or, in the present case, preferably electrically.
- This handle is integrated in terms of circuitry in the control logic already mentioned.
- Such a handle can be adjusted between an effective and ineffective state by electrical or mechanical means. That is e.g. B. in a lock cylinder by key actuation from the outside of the door or by bolt actuation on the inside of the door where the components in the lock cylinder are transferred between a so-called secured or unlocked position or yet another so-called super-secured position. This could also be used in the present rotary latch lock.
- the electrical control requires five pins, which are represented by the aforementioned lines 54, 55 and 17 to 19.
- FIG. 11 shows the electrical actuations of four of these pins 54, 55, 17, 19 along the time axis t drawn there as a function of time.
- the fifth pin 18 is not shown in the control program of FIG. 11 because, as FIG. 10 shows, it is constantly under a negative voltage.
- the top curve 45 is the control curve of the handle. The actuation of the handle affects the control logic.
- the handle is to be actuated, which leads to a pulse 46, which can be seen from curve 45, the length of which depends on the duration of the actuation.
- the control logic responds at tO to the start of the pulse triggered by the handle and sets pin 54, which until then had been at a negative potential, as indicated in FIG. 11, at a time t1 to a positive potential.
- the time difference between tO and tl is only a few microseconds. This reaction between the handle according to control curve 45 via the control logic the pin 54 is illustrated in Fig. 1 1 by an active arrow 47.
- the two pins 54, 55 are at different potential, because the other pin 55 of the motor 50 remains at negative potential.
- the motor 50 is put into operation and the aforementioned forward drive 56 occurs in FIGS. 1 and 2.
- the control cam 51 slides, as can be seen from FIGS. 1 and 2, along with a suitable control profile 41 provided inside edge of the control lever 40.
- This control profile 41 is initially shaped in a circular manner in its initial section to the rotational path of the control cam 51 on the worm wheel 53, which is why, initially, despite the storage force 61 acting on it, there is initially no movement of the storage lever 40.
- control cam 51 reaches more radially extending regions of the control profile 41, which is why the storage lever 40 is increasingly pivoted towards the third working arm 31 in the direction of the arrow 43 by the force 61 acting on it.
- the lever sensor 16 In the closed position of the rotary latch 20 of FIG. 1, the lever sensor 16 is in its position which can be seen in FIG. 10 and which releases the electrical contacts; ie the microswitch 16 is open.
- the outer edge 42 of the storage lever 40 opposite the control profile 41 is used for this in the exemplary embodiment in FIG. 1.
- this could also be done by a control projection 57 provided on the worm wheel 53 and indicated by dash-dotted lines in FIG. 1, which is shown in the output shown in FIG. 1 -Rotating position keeps the actuator pressed on the latch sensor 15.
- Such a switching position of the latch sensor 15 determined by the motor drive via the worm wheel 53 can be carried out particularly precisely.
- This initial rotational position of the worm wheel 53 can also be determined by a fixed rotary stop 58 in the lock housing 11, against which a radial finger 59 provided on the worm wheel 53 can abut.
- This impact action at 58, 59 is not absolutely necessary; a gap could normally be provided here, which avoids noise during the control movements of the components.
- FIG. 1 1 shows, the two pins 54, 55 of the motor are at the same negative level in the period before tO; the electrical lines of the motor are short-circuited, which is why the motor is stopped.
- the pivoting movement 43 of the storage lever 40 comes about by unloading the energy accumulator 60, while the control cam 51 controls this pivoting movement 43 only “braking” in its forward drive 56. As illustrated in FIG.
- the actuator of the latch sensor 15 is still pressed by a suitable rotary latch control profile 26 and therefore held in the open position of its contacts shown in Fig. 10, i. that is, there is a positive potential at pin 19 of the circuit of FIG. 10, as can be seen from the bottom curve in the control diagram of FIG. 11.
- This effect of the control profile 26 was of course also in the previous rotary positions of FIGS. 1 and 2.
- the rotary latch 20 has rotated under the action of its restoring force 22 to such an extent that the actuator of the latch sensor 15 is released by the associated control profile 26.
- the closed contact of the latch sensor 16 in FIG. 10 sets the pin 19 to the negative potential of the pin 18, which corresponds to the time t3 in the control program of FIG. 11.
- the pawl 30 has already reached its pivoting end position in FIG. 4 by the storage force 61, which is why the pawl 30 and the storage lever 40 from then on rest.
- the control cam 51 has been rotated further up to the point in time t3 in the direction of the arrow 56 and has thereby left the storage lever 40.
- the control logic associated with the rotary latch lock responds to the reversal of the latch sensor 15 at time t3 in FIG. 11 and sets the two pins 54, 55 belonging to motor 50 to mirror image potential after a short reaction time, namely at time t4 in FIG .
- This is illustrated by the double arrows 48 in Fig. 1 1.
- Pin 54 is switched to negative and pin 55 to positive potential. This has the effect that the motor 50, which until then has been driven in rotation, initially brakes due to the countervoltage. This should have just been achieved in the rotational position of the control cam 51 shown in FIG. 4. After that, however, the rotation of the motor reverses, so that the reverse drive of the motor and thus of the control cam 51, which can be seen by the rotation arrow 56 'in FIGS.
- the rotary latch 20 when the motor vehicle door is open, is still in the open position, which is determined by the abovementioned stop 12, but in the meantime the motor has turned the control cam 51 further backwards 56 '.
- the control cam 51 has again moved against the control profile 41 of the storage lever 40 and has pivoted it back in the direction of the pivot arrow 43 'of FIG. 5.
- the motor 50 does a work counter to the storage force 61 and the energy accumulator 60 is increasingly loaded.
- the motor 50 no longer needs to do any other work during this reverse drive 56 ′, which is why all the motor energy can be used to charge the energy accumulator 60.
- the pawl 30 remains at rest, although the spring force 33 already mentioned acts on it, also in FIG. 5.
- the spring-loaded pawl is in Fig. 5 and also in Fig. 6 in a "ready position", where it wants to engage radially with its ratchet tooth 37 in corresponding flanks of the rotary arrows 20, but initially by the latch control profile 26 at this point is hindered.
- This voltage change is evaluated by the control logic and after a short reaction time, namely at time t6 of FIG. 11, there is a potential change at pin 55 of motor 50.
- This effect of the control logic is illustrated in FIG. 11 by an arrow 49.
- Pin 55 comes to a negative potential, as the control program of FIG. 11 shows.
- Both pins 54, 55 belonging to the motor 50 therefore again have the same, namely negative potential, which is why the motor 50 is short-circuited and brakes. There is therefore an exact motor standstill without end stops having to be effective.
- Fig. 6 shows such a final state with the door open.
- the energy store 60 is fully charged again.
- a maximum storage force 61 is available.
- the storage lever 40 is in its starting position, which is also present when the door is closed, the pawl 30 is in the standby position described, as long as the locking member 10 'is outside the rotary latch 20 in its release position 10'. If the handle should be actuated inadvertently when the door is open, the control logic ensures that the motor 50 is idling. This is recognized by the control logic in that the latch sensor 15 is on the case 20 remains inactive.
- the spring force 33 acting on the pawl 30 can be achieved by a spring member 27 which is effective between the pawl 30 and the storage lever 40.
- a spring member 27 which is effective between the pawl 30 and the storage lever 40.
- a two-leg torsion spring can be used, which is fastened to the common axis 34 of the pawl 30 and the storage lever 40 and with its two legs 28, 29 drives the pawl working arm 31 on the one hand and the storage lever 40 on the other hand in the mutual movement direction.
- These two components 40, 31 are prevented from doing so because the storage lever 40 abuts on the control cam 51 and the pawl 30 on the latch control profile 26.
- the pawl 32 could receive the spring force 33 described from its own spring.
- the energy accumulator 60 acting on the storage lever 40 is only indicated schematically in the drawings; specifically, it could consist of a two-legged spring, one end of which is supported on the housing and the other end exerts the storage force 61.
- FIG. 7 shows a rotational position of the rotary latch which corresponds to the conditions described in FIG. 2 in the normal case.
- the pivoting movement 36 of the jack actuator arm 32 is stiff, which, for. B. may have resulted from a previous crash of the motor vehicle.
- the storage force 61 of the storage lever 40 described in connection with FIG. 2 is not sufficient to move the pawl 30 via the contact point 35 to be able to lift out of the catch 20.
- FIG. 8 A limit situation has just been reached in FIG. 8 where the control cam 51 has, due to its further movement 56, reached the control profile 39 provided on the inner edge of the pawl actuating arm 32 and moves along it, as can be seen from FIG. 9. During this further rotation 56, the control cam 51 exerts an additional opening force 63, which can be seen in FIG. 8, and which is additive to the storage force 61 exerted by the storage lever 40 via the contact point 35. This now practically doubled energy is sufficient to overcome the inhibition of the components and to execute the desired pivoting movement 36 on the pawl 30.
- Fig. 9 The pawl working arm 31 has left the position of the rotary latch, which until then has been shown in dash-dotted lines, and has reached its open position, drawn in full lines, under the action of its restoring force 22.
- the closing member can be moved into its release position 10 '.
- FIG. 9 describes conditions which are analogous to that of the one in FIG. 4 is the normal case described.
- the correspondence consists in the fact that in Fig. 9 and in Fig. 4 the actuator of the latch sensor 15 has been released and therefore from then on reverses the motor with its reverse drive 56 already described in connection with Fig. 5.
- a comparison shows, however, that in the special case of FIG. 9 the motor has moved the worm wheel 53 by a considerably larger angular amount 64 than in the situation of FIG. 4 which corresponds to the normal case applied in a special case and has been used to open the stiff rotary latch 20.
- FIGS. 4 and 9 shows that, in the special case of FIG. 9, the energy accumulator 60 has also discharged considerably more and therefore an additional energy for opening the catch 20 has been applied by the storage force 61. All this is possible with economical energy exploitation on the motor 50; the motor can be designed to be weak and thus space-saving.
- the end position of the forward drive 56 from the control cam 51 shown in FIG. 9 can also be ended in that a further rotary stop 38 has become effective.
- the finger 59 on the worm wheel 53 already mentioned in connection with FIG. 1 comes to rest with the rotary stop 38 and has thereby stopped the further rotation of the motor 50 in any case.
- the control logic can also respond in the alternative to this attack situation and this electrical way, for. B. notice by a correspondingly high energy consumption of the engine in the event of a stroke.
- the reversal of the motor 50 and thus the reverse drive 56 'of the control cam 51 already described in connection with FIGS. 4 and 5 commences, which finally also in this special case corresponds to the standby position of the pawl 30 of FIG 6 leads with the catch 20 open.
- the energy accumulator 60 is loaded again, which in the special case of FIG. 9 takes place over a correspondingly larger angular range compared to the backward movement 56 ′ shown in FIG. 5.
