Definitions
- the invention relates to an electromotive actuator for a central Matverriege solution of a motor vehicle, which actuator has the features from the preamble of claim 1.
- An electromotive actuator which has all the features from the preamble of claim I including the feature mentioned as being particularly advantageous is known from DL-OS 36 27 893.
- This actuator has a z. B. from DL-OS 32 10 923 known electromotive actuator the advantage that the slide from the end positions also
- the door lock system of a motor vehicle not only permits central locking or unlocking of a motor vehicle door, but also a so-called anti-theft device.
- a door lock can be locked and unlocked from the outside. This is also basically possible with a handle inside the motor vehicle.
- the anti-theft device is also set from the outside, there is one
- Unlocking the door lock with the handle inside is no longer possible. In this way, thieves access to the interior of the motor vehicle is to be made more difficult. If the window of a motor vehicle has been broken in, it is not possible to unlock the door with the handle inside and then open it. Entry is only possible through the henster.
- the invention has for its object an electromotive
- an anti-theft device is provided without excessive loads on the actuator in the event of an attempted break-in, and in which actuator manual unlocking from the outside is also possible if the anti-theft device is not reset by a motor can be.
- the second slide can be coupled to the first slide via a pawl, which is transverse to one of the two slides
- Direction of movement of the slider is adjustable and engages under the Wi tion of a spring element in the other slider.
- the two slides can be regarded as a single slider for the movement sequence, so that unlocking is readily possible from inside the motor vehicle.
- For theft protection is the
- Pawl retractable from a second electric motor via a control element from engagement in the other slide against the action of the spring element.
- Slider be it the latch on it or on the first slider, movable, but the door lock cannot be unlocked.
- the forces introduced into the handle inside the motor vehicle do not have to be absorbed by parts of the actuator, since the second slide can be moved.
- the first slider regardless of whether the pawl is guided on it or not, can still lock in from the outside or from the first electric motor the unlocking position are brought.
- this also means that when unlocking the door lock from the anti-theft position of the pawl, a special sequence in the operation of the pawl and the displacement of the first slide need not be observed.
- the electromotive actuator according to claim 2 also provides a solution to the problem.
- This actuator also has a first slide which can be connected in a direction-independent manner to a door lock of the motor vehicle and a second slide which can be coupled for unlocking with a handle inside a motor vehicle is. Both sliders grip across with a projection and a recess
- a driver of one of the two sliders can be moved relative to the slider in the direction of movement of the two sliders.
- the second slide can be opened again move freely from the handle inside the motor vehicle without taking the first slide with it and thus unlocking the door lock.
- Adjustment of the first slide possible without having to move the first electric motor and a transmission arranged after it.
- the second slide from the first slide in the direction of unlocking regardless of the pawl.
- the second slide can be taken with the first slide immediately from the outside without the anti-theft device having been reset by the second electric motor beforehand.
- the control member is a control cam with a ramp. From the basic mode of operation, it is unimportant whether the direction of movement of the ramp on the latch when it is retracted, aiso when the anti-theft device is set, corresponds to the direction of the slide when locking or unlocking. However, it appears to be more advantageous if the ramp moves according to claim 7 when the pawl runs in such a direction that corresponds to the direction of movement of the slide when locking. A force is then not exerted on the pawl from the ramp in the direction of unlocking of the slides, so that there is no danger that the slides move somewhat out of the locking position and the setting of the anti-theft device is made difficult or not possible at all.
- Lürverriegelungsan were usually working reliably on electric motors used in motor vehicles over a long period of time, so it can not be excluded that such an electric motor should fail, the transmission members downstream of the electric motor can then be located in any undetermined position. Locking a door by hand must then still be guaranteed. How this problem can be solved with regard to the first electric motor is described in detail in DE-OS 36 27 893. For the second electric motor, this problem is solved in an advantageous manner according to claim 8 dadurcti that the pawl can be pushed under the control cam when the slide is adjusted from the unlocking position into the locking position.
- Control curve is designed such that the pawl at a
- the ramp can be pushed or can be pushed under the ramp.
- the ramp at its foot should be separated from its carrier.
- the distance must not be large to ensure that the pawl runs onto the ramp.
- the foot of the ramp When shaping the control curve, which is usually injection molded from plastic with its Iräger, the foot of the ramp must therefore be separated from the Iräger by a tool section that is as thin as possible. So that this thin tool section does not have to be so long, the ramp is thinner at its foot than at a distance from its foot.
- the control cam is preferably located on one of the second
- the control cam is arranged in such a way that the pawl can be moved by it in the direction of the axis of the gearwheel.
- the control curve advantageously has a plateau section without a change in height.
- the second electric motor continues to follow an indefinite path which, owing to the plateau section of the control curve, cannot affect the position of the pawl. If the pawl is guided on the second slide, it is inserted into the
- the plateau section according to claim 17 has on its radially outer edge a sloping slope in the radial direction.
- the second electric motor can be used both to retract the pawl and to advance the pawl through the spring element
- the second electric motor can only be switched on for pulling back the pawl, the gearwheel preferably being rotatable through 360 ° after each switching on of the electric motor.
- the number of switching operations and, if the gearwheel is rotated less than 360 ° in each case, the total operating time of the second electric motor can be reduced.
- only one break contact is required as a limit switch, so that the number of
- the second electric motor can only be switched on when the slide has reached the locking position and this by a signal, for. B. an electrical switch in the door lock has been reported.
- a time delay could, however, also be created in that the motors are switched on at the same time, but the gearwheel with the control cam runs considerably slower than the gearwheel. with the crank adjusting the slider or, in the event that the gearwheel with the control cam is rotated 360 °, the ramp only after one
- Adjustment of the slide by the first electric motor is necessary, can be very different.
- Actuator with regard to the arrangement and guidance of the pawl can be found in the subclaims 24 to 29. So is in the preferred
- the spring element of a coil spring which is located in a blind bore of the pawl and is supported on an attachment of the pawl guiding the slide, which attachment by a
- the jack is then very long and can be made correspondingly long.
- the path of the pawl out of its guidance is advantageously limited by a stop of the slide not guiding the pawl. A stop on the slide guiding the pawl is thereby avoided, so that the pawl is easily inserted into the guide can be.
- the helical spring is well supported laterally in each position of the pawl.
- the space available can make it appear favorable that the pawl is guided on the second slide according to claim 28. If, on the other hand, the pawl is guided on the first slide, it is not carried along when theft protection is set and the handle is actuated inside the vehicle, which leads to a movement of the second slide, but remains on the control curve. There is no need to take precautions to ensure that the jack z. B. remains by a support surface on the first slide or on the housing in the anti-theft position or is pushed back into this position when the second slide returns.
- the whole construction of the lock, electromotive actuator and handle inside the vehicle and the mechanical connections between these parts can be chosen such that the second slide can only be actuated via the handle inside the vehicle in the sense of unlocking the door lock. So that a locking via the handle inside is possible, it is provided according to claim 31 that the slide can be coupled via a driver with the handle inside the motor vehicle and that the driver is in the direction of movement of the slide between them. If, on the other hand, the second slide can be actuated via the handle inside the motor vehicle both in terms of locking and in terms of unlocking, the second slide can advantageously be directly positively coupled to the driver in both directions of movement.
- Subclaims 33 to 3b included. It is particularly favorable that only one slide is guided on the housing and the other slide on the first slide. Correct assembly of the two sliders to one another is ensured by training according to claim 35. In an electromotive actuator according to claim 2 is after
- Claim 36 in an advantageous manner the driver against the action of a spring element which is supported on the associated slide. It also appears favorable if the driver can be coupled in a position to the associated slide by a limit force lock. Basically, this can be done in both operating positions of the driver in relation to the associated slide.
- An electromotive actuator according to claim 2 is particularly suitable for using only a single reversible electric motor for locking and theft protection, with which the driver is adjustably coupled.
- the coupling of the driver with the electric motor can, for. B. take place via a gear driven by the electric motor and a rack of the driver. The right one
- Theft protection advantageously coincides with the direction of rotation during unlocking.

- a first electric motor 23 is fixed in a two-part housing 20 with a housing pot 21 and a cover 22 made of plastic, which has a worm 25 seated on its shaft 24, a worm wheel 26 and an integral part thereof Worm gear designed, but not shown pinion
- crank wheel 27 From this crank wheel 27 projects a conical tapering crank pin 28, which consequently moves on a circular path.
- the axis of the worm wheel 26 is designated 29.
- a slide 30 is guided in a longitudinally movable manner, which can be connected via a U-shaped recesses 31, which are located on a projection 32 protruding from the housing 20, to a push rod, not shown, which can be connected to a Door locking mechanism in a motor vehicle acts.
- a bracket 35 of the slide 30 which extends parallel to the cover 22, namely — in the plan view according to FIG. 1 — on the underside of the bracket 35, two stops 33 and 34 are provided, which interact with the crank pin 28. It can be seen from Figure 1 that the distance B between the two stops 33 and 34 in the adjustment direction of the slide 30 is very much smaller than the radius of the crank, i. H. thus much smaller than the distance between the crank pin 28 and the axis 29 of the crank wheel 27. This enables a large stroke of the slide 30 for a given one
- Adjustment direction of the slide 30 is only slightly larger than that
- crank pin 28 seen transversely to the adjusting direction of the slider 30, between the two stops 33 and 34.
- the slider 30 is thus completely decoupled from the crank pin 28 or the crank wheel 27 and can be smoothly moved manually by the push rod shown end position in the other end position and be changed back.
- the crank wheel 27, the crank pin 28 and the slide 30 are in the other end position in which the crank wheel is rotated by 180 ° with respect to the position shown in FIG. 1.
- crank pin 28 strikes the stop 34 of the slide 30 and returns the slide to the end position shown in FIG. 1, which corresponds to a locked door.
- crank pin 28 is driven by an angle of 180 ° in the same direction of rotation in each setting process.
- the crank pin 28 is only coupled to the stops 33 and 34 during its movement, in the end positions after one each
- the slider 30 is substantially parallel to a side wall of the
- Housing 20 arranged and engages with the thin arm 35 parallel to the cover 22 and just below this in the housing pot 21.
- a second slide 40 is guided therein, the direction of a possible movement of the second slide 40 relative to the first slide 30 coinciding with the direction of the double arrow A.
- the second slide 40 has two strips 41 on the side, which engage in grooves 42 of the first slide 30 which are open at one end for introducing the second slide 40 into the first slide 30.
- one side wall 43 of the grooves 42 is higher than the other side wall.
- the strips 41 on the side facing the side wall 43 are higher than on the other side, so that the slide 40 can only be inserted into the slide 30 in a single relative position thereof.
- the open end of the grooves 42 is located on the end face 44 of the slide 30.
- the two strips 45 of the slide 30, in which the grooves 42 are located, are only in the area of the extension 32 and at the other end of the grooves 42 connected.
- the second slide 40 can therefore reach out between the end face 44 and the extension 32 of the first slide 30 with an extension 46 through the same opening 47 in the side wall 48 of the housing 20, through which the slide 30 with the extension 32 also does so.
- a groove 49 in the extension 46 of the second slide 40 a not shown
- Driving plate are used, the z. B. can be operated via a Bowden cable from a handle inside a motor vehicle. Driving plate and second slide 40 are thus positively coupled to one another in the direction of the double arrow A. In normal operation, the two approaches 32 and 4b lie directly against one another, as shown in FIG. 1.
- a pawl 50 is guided thereon perpendicularly to the adjustment direction of the slide, which is indicated by the double arrow A in FIG. 1, and perpendicular to the cover 22 of the housing 20.
- the pawl 50 engages with two lateral strips 51 in two grooves 52 of the slide 40, which are formed by two inverted L-shaped strips 53 placed in one piece on the slide.
- the pawl has a blind bore 54 in the guide direction, which opens into a longitudinal slot 55 toward the slide 40. The width of the slot is, however, less than the diameter of the blind bore 54, so that one inserted into the blind bore 64
- Helical compression spring 5b cannot fall out of the blind bore 54 through the slot.
- the helical compression spring is supported on the bottom of the
- a first end position is indicated by solid lines and a second end position of the pawl 50 by dashed lines. It can be seen that the abutment 57 is covered in every position of the pawl 50 by the wall 58 opposite the longitudinal slot 55, so that the helical compression spring 5b is securely supported on the abutment 57 in the predetermined position.
- the grooves 62 of the slide 40 are open on both sides and the strips 51 of the pawl 60 are the same throughout, so that the pawl can be easily pushed in the direction of the support surface of the helical compression spring 56 on the abutment 57 into the second slide 40.
- the helical compression spring extends the head 59 of the pawl 50 so far can push in until the pawl strikes with a step on the side of the boom 35 facing away from the cover 22.
- the dimensions of the opening 48 and the head 59 of the pawl 50 are coordinated with one another in such a way that there is only a slight play between them.
- the slide 30 and 40 are coupled to each other in both directions of movement. From the abutting of the two approaches 32 and 46 also shows that from the end position shown in Figure 1 of the two slides, which corresponds to a locked door lock, the slider 30, the slider 40 with the approach 32 regardless of the pawl 60 in the
- the pawl 50 engages in the opening 58, it is also possible to unlock or lock a motor vehicle door with the inner locking handle. If the door is locked and the inner locking handle is now actuated, the second slider 40 and the first slider 30 are carried along via the drive plate, not shown, which is located in the groove 49 of the shoulder 4b of the second slider 40, and the pawl 50 transfers the movement to the door lock. During a locking process, the slide 40 takes the first slide 30 with it via the shoulder 4b or the pawl 50.
- Breakthrough 58 of the slider 30 can be withdrawn provided the two sliders 30 and 40 are in the locking position and the electric motor 65 is energized.
- the electric motor 65 similarly to the electric motor 23, finally drives a gearwheel 70 via a worm 67 seated on its shaft bb, via a worm wheel b8 and via a pinion 69 formed in one piece with this worm wheel, which gearwheel just below the arm 35 of the slide 30
- Gear ring 71 is provided and, seen from the boom 36, has a control cam 75 beyond the gear ring 71, which is located at a distance from the gear ring 71 on the side of a radial flange 76 of the gear wheel 70 facing away from this gear ring.
- the control curve 75 extends over an angle of approximately 205 ° and consists of a ramp 7 7 rising from the underside of the ring gear 71, which extends over an angle of approximately 60 °, and a plateau section 78 adjoining the ramp, the length of which is about 245 °. At the end of 79
- Plateau section abruptly breaks off the control curve.
- the flange 7b carrying the control cam 75 is cut away from the ring gear 71 against the ring gear 71 by a circumferential groove 80 which is open radially outwards.
- the groove 80 is wider than a cam follower 81, which is formed in one piece with the pawl 50 and protrudes from the pawl 50 perpendicularly to its guide direction toward the control cam 75 and, as can be seen from FIG. 2, when the pawl 50 is snapped into the slide 30 is located just below the ring gear 71 at the level of the groove 80.
- the groove 80 also continues below the ramp 77, but there initially decreases continuously in width in accordance with the inclination of the ramp, then again has a section with a constant width because the ramp 77 becomes thinner and finally decreases in it Spread close to zero. That the ramp 77 is thinner at its base than at a distance from it Tool-technical reasons, namely the ramp is not only separated radially on the outside, but also at its base 82 from the remaining material of the gearwheel 70. However, in order to ensure that the curve follower 81 runs smoothly onto the ramp 77, the distance between the foot 82 of the ramp 77 and the remaining material of the gearwheel 70 may only be small. This small distance must be created with a section of the mold that is only very thin and therefore prone to breakage.
- the ramp 7 7 is also separated from the rest of the material of the gear 70 radially on the inside by a cutout 83 which can be demolded through an opening 84 in the toothed ring 71 of the gear 70.
- the free cut 83 viewed in the circumferential direction, begins at a distance in front of the foot 82 of the ramp 77 and ends shortly after the transition between the ramp 77 and the plateau section 78 within the plateau section 78. Only at this Transition, the ramp 77 is connected to the rest of the material of the gear 70. It can therefore spring away well from the ring gear 71.
- the gearwheel 70 also carries a radial cam 85 with which a limit switch 86 for the electric motor 65 accommodated in the housing 20 can be actuated.
- the switch 86 is a changeover contact, which is controlled by the cam 85 in such a way that the electric motor 65, which always runs in the same direction of rotation, is switched off each time the gear 70 is rotated by approximately 180 °.
- the position of the cam 85 and the position of the control cam 75 are coordinated with one another in such a way that the curve follower 81 of the latch 50 is short in one rest position of the gear 70 shortly before the ramp 77 and in the other rest position of the gear 70 is in front of the end 79 of the plateau section 78, provided that the sliders 30 and 40 are in the locking position.
- the slider 40 takes the slider 30 into the unlocking position via the pawl 50, so that the lock is unlocked. So theft protection was not set. If the lock and the anti-theft device are to be set, a signal is given by a longer actuation of the locking cylinder, by a further actuation of the locking cylinder or by actuation of the locking cylinder beyond a certain distance, on the basis of which the second electric motor 65 is energized, when the slider 30 is in the locking position.
- the electric motor 65 rotates the gear 70, viewed in the view according to FIG. B, clockwise by 180 ° until it is switched off by the switch 8b.
- the control curve 75 moves with the ramp 77 under the curve follower 81 of the pawl 50 and pulls it out of the opening 58 of the slide 30, the path of the pawl 50 being determined by the height of the plateau section 78 of the control curve 75.
- the cam follower 81 of the pawl 50 is close to the end 79 of the plateau section 78, while before the 180 ° rotation of the
- Movement of the slider 40 can easily remove the pawl 50 from that
- Plateau section 78 of the cam 75 are moved tangentially away.
- the curve follower 81 has left the plateau section 78, the pawl is supported on a wall of the slide 30 so that it essentially maintains its height with respect to the control curve 76 and slides along the slide 30 with the slide 40. If the inner locking handle is moved back again, the slide 40 also moves back into the position shown in FIG. 8, the cam follower 81 again on the
- Plateau section 78 of the cam 75 arrives. In order to facilitate this running onto the plateau section 78, this is provided with a bevel 87 radially on the outside, as shown in particular in FIG.
- the inner locking handle and with it the slide 40 remain in the Unlocking position, so when unlocking from the outside, the slide 30 is adjusted, the pawl 50 engaging in the unlocking position of the slide 30 due to the force of the spring 56 engaging in the opening 58 of the slide 30, and thus both slides are coupled again.
- the gear 70 can then be in the rest position according to FIG. 6 or in the rest position according to FIG. 8, but also in any intermediate position.
- the path for the curve follower 81 of the pawl must be free. If the gearwheel is in the position according to FIG. 6, which corresponds to the anti-theft device not set, the pawl 50 can be moved freely, so that locking is possible. This also applies if the circumferential section of the gearwheel 70 which does not carry a cam is in the path of the cam follower 81. On the other hand, if the gearwheel 70 assumes its other rest position, which is shown in FIGS. 8, 10 and 77, the groove 80 between the flange 76 and the ring gear 71 of the gearwheel 70 enables it to be locked. Because during this locking the cam follower 81 can be pushed into this groove, as can be seen in particular from FIG. Is currently the ramp 17 in the way of
- Curve follower 81 this lifts the ramp due to its resilient
- the direction of rotation of the gearwheel 70 when the cam follower 81 runs onto the ramp 77 is selected such that a force component occurring during the run-up acts in the direction of movement of the sliders 30 and 40 in the locking direction. Since the slider abuts a stop in this direction, this force cannot influence the position of the slider.
- This direction of rotation also means that if the power supply fails, the ramp 77 can be passed underneath and the curve follower 81 does not run onto the ramp if it should happen to be in the area of the curve folder. In this way it can be achieved that in the event of the power supply for the electric motor 65 failing, the anti-theft device is in no case set via the internal locking handle.
- a first slide 30 and a second slide 40 are again present.
- the second slide consists of two parts 95 and 96, which are in the direction of movement: the slide, which is again indicated by the double arrow A, is at a distance from one another.
- the part 96 may be referred to as a driver since it can be moved relative to the part 95 in the direction of arrow A by an electric motor 97 when the part 95 of the slide 40 is at rest relative to the slide 30.
- the driver 96 is provided with a rack section 98, into which a pinion (not shown) of the electric motor 97 engages.
- a recess 99 is formed, into which the slide 30 engages with a projection 100.
- the two parts 95 and 96 of the slide 40 are pulled towards one another by a helical spring 101.
- a detent spring 102 is fastened to the part 95 of the slide 40, which engages over the driver 96 and can engage with a grid 103 in a latching receptacle 104 of the driver 96. The locking is released at a certain force in the direction of movement of the slide, so that the detent spring, grid and
- Snap recording can be called limit force lock.
- the slide 30 can also be guided on a housing in the case of the one according to FIGS. 13 and 14, while the parts 95 and 96 of the slide 40
- the electric motor 97 is a reversible motor which is used for
- the slides 30 and 40 may be in their locking position. If the motor is now in the direction of the Arrow G switched on, it pushes the driver 96, in the view according to FIG. 13, to the left, and driver 96 takes the slide 30 with it via the projection 100, so that the lock is unlocked. When locking, the electric motor 97 rotates in the other direction H, with part 96 of the
- Unlocking end position of the leils 95 are moved before the driver 96 takes the slide 30 after releasing the locking between the grid 103 and the locking recess 104.
- Coil spring 101 to be dispensed with, if it is accepted that, in the event of a lock, initially only the driver 96 is moved while increasing the recess 99 until the grid 103 engages in the latching recess 104 and then also adjusts the leil 95 of the slide 40 and the slide 30 become.
- unlocking only the leile 95 and 96 of the slider 40 would be moved before the slider 30 is taken along.
- the anti-theft device would be set before locking and reset only after unlocking.
