Definitions
- the invention relates to an actuating device for a motor vehicle lock, in particular a motor vehicle door lock closing device, with an electric motor drive and a lever arrangement following the drive, the lever arrangement being equipped with two actuating levers which are pretensioned against one another by a spring and are pivotably connected to one another, and wherein the actuating lever on the output side works directly or indirectly on an actuating element.
- Actuating devices for a motor vehicle lock are known in many ways. In principle and by way of example, this can be an opening aid, with the aid of which the associated motor vehicle lock is opened by an electric motor. In general, however, the actuating device is designed as a closing device.
- This closing device is used by way of example and not by way of limitation in motor vehicle tailgate locks or motor vehicle side door locks as motor vehicle door locks. In principle, of course, other locks belonging to motor vehicle locksmiths can also be equipped with such a closing device, for example motor vehicle locks on tank flaps, loading flaps or also those on and in connection with motor vehicle seats.
- the force required at this point is transmitted via a Bowden cable to a closing pawl, which in turn interacts with an associated contour on the catch.
- the means for detecting the position of the movable component of the closing device are arranged on the rotary latch for this purpose.
- the invention is based on the technical problem of further developing such an actuating device for a motor vehicle lock and in particular a motor vehicle door lock closing device in such a way that force peaks can be determined properly and independently of the position in relation to the closing device.
- a generic actuating device for a motor vehicle lock is characterized within the scope of the invention in that a sensor is provided which detects a relative movement of the two levers as essential components of the lever arrangement with respect to one another.
- any force peaks occurring on or in the Zuziehein direction or generally the actuating device are therefore in directly recorded and recorded by the institution in question.
- the relative movement of the two levers to one another is used for this purpose.
- the invention is based on the knowledge that the two levers are pretensioned against one another by the spring and consequently assume and maintain a certain angle to one another in normal operation. This means that in normal operation the spring ensures a quasi-rigid rotational coupling of the two levers with one another.
- this peak force corresponds to the fact that the actuating lever on the input side, which is acted upon with the aid of the electric motor drive, will continue to move as before, but the actuating lever on the output side will drive the movement cannot (no longer) follow the action due to, for example, a blockage.
- the two actuating levers move relative to one another, their relative movement to one another at the same time leading to the fact that the spring coupling the two actuating levers to one another is compressed or lengthened depending on the preload.
- the relative movement of the two levers to one another generated by the observed force peak is detected with the aid of the sensor and generally corresponds to the fact that an angle enclosed by the two levers experiences a change.
- control lever acting on the sensor is advantageously provided within the scope of the invention.
- the control lever can be rotatably mounted on one of the two actuating levers.
- the design is usually made such that the control lever can be acted upon with the aid of the other operating lever that is complementary and not used for mounting it.
- control lever is rotatably mounted on one of the two actuating levers, at this point both the input-side Actuate transmission lever and the output-side actuating lever for the corresponding Storage can take care of. If there is now a force peak due to an impending trapping situation, a relative movement of the two levers to one another corresponds to this, which means that the control lever is acted upon with the aid of the respectively complementary actuating lever. Since the control lever in turn acts on the sensor, relative movements between the two levers associated with force peaks can be easily determined in this way.
- the design is also advantageously made such that the control lever works on a pushbutton element.
- the sensor for its part now detects movements of this probe element.
- the procedure is usually such that the control lever has a control curve that acts on the feeler element for the position-independent application of the feeler element. That is, the control cam is designed so that - regardless of the position of the actuating levers to each other or their common position compared to the actuating element - their relative movement can be detected with the aid of the control lever and sensed by the sensor.
- a position-independent detection of force peaks is achieved with the aid of the sensor. This is necessary for particularly sensitive operation and also against the background that ultimately every trapping case should be evaluated in the same way.
- this force peak should be recorded regardless of the position in which the two levers are located. Transferred to the motor vehicle door to be closed, this means that the sensor responds from a certain force peak within the door gap, regardless of whether the door gap is large or small. This is of particular advantage for a particularly safe and customer-accepted operation.
- the senor works in such a way that it queries movements of the probe element in a contactless or tactile manner. If the sensor works without contact, there is an inductively functioning sensor and / or at this point one on an optical or resistive basis has proven to be particularly favorable. In the case of an inductively operating sensor, it is usually a Hall sensor which detects movements of an associated permanent magnet connected to the probe element. In principle, the pushbutton element itself can also be designed as a permanent magnet.
- the sensor works optically, for example a marking scanned with the aid of a light beam or a sequence of markings on the probe element can be detected.
- the sensor tactile queries movements of the probe element This is usually the procedure for a resistive sensor, that is to say in the broadest sense of a sliding resistor, in which case a corresponding change in resistance is made with the aid of the probe element.
- the actuating element ultimately acted upon with the aid of the actuating device with the interposition of the lever arrangement is, in the case of a closing device, basically a rotary latch or a lock holder.
- the closing device ensures that, for example, following a manually brought about pre-latching position of the rotary latch, the electromotive drive works on the lever arrangement in such a way that the rotary latch is drawn into its main latching position starting from the pre-latching position.
- a so-called servo lock holder can also be used.
- the lock holder is again acted upon and moved with the aid of the drive of the actuating device following the pre-locking position reached by the rotary latch, for example, so that the lock holder that has fallen into the rotary latch transfers the rotary latch from its pre-locking position to the main locking position.
- a rotary latch sensor assigned to the rotary latch can be implemented to detect the pre-latching position.
- a control unit evaluating signals from the rotary latch sensor ensures that the electromotive drive as part of the actuation device is energized and, for example, ensures that the rotary latch is transferred from its latching position to the main latching position.
- this is determined with the aid of the additional sensor and transmitted to the control unit in question.
- the control unit can switch off the electromotive drive immediately or also reverse it in order to be able to open the associated motor vehicle door. All of this succeeds regardless of how large the door gap observed between the associated motor vehicle door and the motor vehicle body in the event of a jamming is dimensioned, ie independent of the position.
- the entire actuation device can be integrated into the motor vehicle lock. This also applies regardless of the drive and a Bowden cable that is usually provided at this point. As a result, the construction is simplified overall and in addition, and the assembly can also be represented more easily. This is where the main advantages can be seen.
- Fig. 1 the actuating device according to the invention in a first Ausry approximately variant
- Fig. 2 the actuating device according to the invention in a second Ausry approximately variant.
- the figures show an actuating device for a motor vehicle lock shown. According to the exemplary embodiment and not by way of limitation, it is particularly a matter of a motor vehicle door lock device.
- This ver generally has an electric motor drive 1 and a lever arrangement 2, 3 following the drive 1. With the aid of the lever arrangement 2, 3, actuating movements of the drive 1 are transmitted to an actuating element 4.
- the actuating element 4 is a rotary latch 4, while a lock holder 4 'is used as the actuating element 4' in the further second embodiment variant according to FIG. 2 at this point.
- the drive 1 may work on an input-side actuating lever 2 of the Hebelan arrangement 2, 3 via a Bowden cable (not shown) or a drive worm.
- the output-side lever 3 of the lever arrangement 2, 3 may also provide the Stellbe movement on the rotary latch 4 or on the lock holder 4 nie via a Bowden cable.
- the electromotive drive 1, with the interposition of the lever arrangement 2, 3, ensures that the rotary latch 4 is generally pulled shut from its pre-locked position to its main locked position.
- the pre-locking position of the rotary latch 4 is first detected with the aid of an indicated rotary latch sensor 5, the signals of which are recorded and evaluated by an associated and connected control unit 6.
- the sensor 7 is a contactless sensor 7 which, according to the exemplary embodiment, functions inductively and is preferably designed as a Hall sensor 7.
- movements of a feeler element 8 queried which is equipped with one or more permanent magnets due to the inductive mode of operation of the sensor 7 or can be designed as a permanent magnet itself.
- arrow movements of the movable probe element 8 with respect to the stationary sensor 7 indicated in FIGS. 1 and 2 cause the sensor 7 to respond and transmit the movements of the probe element 8 to the control unit 6 for evaluation there.
- movements of the feeler element 8 correspond to the fact that the two levers 2, 3, as part of the lever arrangement, perform a relative movement to one another.
- the two levers 2, 3 are pivotably connected to one another and assume an extended course indicated in FIG. 1 or an overlapping arrangement (FIG. 2) with respect to one another. This is ensured by a spring 9 which prestresses the two levers 2, 3 against one another.
- the two levers 2, 3 are pivotably articulated and overlap one another.
- the spring 9, which is also prestressed in this case, ensures in normal operation that both levers 2, 3 have the maximum overlap with one another in normal operation, indicated there by being drawn.
- the input-side lever 2 follows unchanged the drive movement of the electric motor drive 1, which corresponds to a pivot movement indicated in FIG. 1 about a common axis 10 clockwise.
- the output-side lever 3 follows the pivoting movements of the input-side lever 2 about the common axis 10 in phase, for which the spring 9 pretensioning the two levers 2, 3 ensures.
- FIG. 2 in which both levers 2, 3 are moved in phase during normal operation and as a result, the lock holder 4 ′ arranged on the lever 3 on the output side is moved.
- control lever 11 is mounted on one of the two actuating levers 2, 3 with a reduction in the included angle, specifically the actuating lever 3 on the output side. 3, the control lever 11 is acted upon with the aid of the other operating lever 2, which is complementary and does not serve to support it.
- This action on the control lever 11 in the event of a relative movement between the two actuation levers 2, 3 corresponds to the previously mentioned counterclockwise movement of the control lever 11 about its axis 12.
- a control cam 11 a works on the control lever 11 on the feeler element 8 and ensures that the feeler element 8 is displaced relative to the sensor 7, which directly indicates a force peak and the relative movement associated with it between the two levers 2, 3 .
- Corresponding signals from the sensor 7 are recorded by the control unit 6 and evaluated.
- the spring 9 ensures that the two levers 2, 3 resume their original position shown in solid lines in FIGS. 1 and 2 after the force peak has ceased to exist.
- the case of jamming described corresponds to the fact that the electric motor drive 1 can be switched off or reversed with the aid of the control unit 6. As a result, the associated motor vehicle door is immediately exposed and any adverse effects on the operator are avoided.
