Definitions

  • the present invention relates to an actuator in a motor vehicle according to the preamble of claim 1.
  • An actuator in a motor vehicle is for example for seat adjustment, in a window or in a motor vehicle lock, z. B. for controlling various functions such as anti-theft device, child safety device, nor-male fuse and arming provided.
  • an actuator of a motor vehicle lock is known (EP 1 178 172 A2), with the reproducible two end positions of an actuating element can be approached, in addition, the manual adjustment between these two end positions is provided.
  • the end positions are approached in block mode.
  • an adjustable locking element is provided, which is adjustable in the movement path of the adjusting element.
  • a complex control mechanism is provided with a cam control. This is expensive and prone to failure.
  • an actuator which has a rotatable adjusting element and a pivotable locking element.
  • the blocking element is prestressed into its starting position and has a driver which engages during a setting cycle with a force transmission element arranged on the adjusting element.
  • the blocking element is adjusted in the direction of a blocking position.
  • the force transmission element releases the driver, so that the blocking element, unhindered by the force transmission element, could basically pivot back in the direction of its starting position.
  • the above actuator is not optimal insofar as the secure locking of the actuator requires a high drive speed. If the actuator is rotated too slowly, the blocking element from the blocking position returns prematurely back to the starting position, so that a blocking of the actuating element fails.
  • the present invention is based on the problem to provide an actuator which is optimized with respect to reaching its blocking position.
  • the basic advantage of the invention is that the actuator comes into blocking engagement with the locking element regardless of its speed of movement during a setting cycle. This is realized in that the locking element falls after the release of the driver, driven by its bias, with its counter-stop on the stop of the actuating element in a catch position. Such a collection of the locking element initially causes the engagement between the stop of the actuating element and the counter-stop of the locking element.
  • the catch position is at the same time the above-mentioned blocking position, so that it comes immediately after the capture of the locking element to block the control element.
  • a further preferred embodiment provides that only a further adjustment of the actuating element out of this state caused by the engagement between the stop and counter-stop the pivoting of the locking element in the blocking position.
  • the blocking element located in the blocking position is reset when the drive motor is switched off due to its bias in the direction of its initial position.
  • the adjusting element is then slightly returned against the previous direction of movement, so that the locking element can pivot freely in its initial position.
  • the actuator is thus reset at least so far that the locking element is no longer held by the stop of the actuating element.
  • the adjusting element is then rotatable in the same direction of movement as before.
  • the stop of the adjusting element and / or the counter-stop of the blocking element for the above provision of the actuating element on a corresponding run-on slope.
  • the force transmission element arranged on the actuating element is simultaneously the stop of the actuating element. This allows a particularly simple and inexpensive production of the actuating element.
  • Fig. 1 shows an actuator 1, as it is commonly used in a motor vehicle.
  • the actuator 1 has a drive motor 2, a rotatable about its axis of rotation 3 actuator 4 and a pivotable about its pivot axis 5 locking element 6.
  • the actuator 4 is driven by the drive motor 2 in actuating cycles that end with the blocking of the actuating element 4 by the blocking element 6.
  • the blocking element 6 has the initial position shown in Fig. 1, in which it is biased.
  • the bias voltage is effected in the embodiment shown here by a spring 7. However, it can also be done by an elastic design of the locking element 6 or in other ways. If the blocking element 6 is designed to be elastic, the pivoting of the blocking element 6 also means bending out of the initial position.
  • the blocking element 6 has a driver 8 and the adjusting element 4 has a force transmission element 9.
  • the driver 8 of the blocking element 6 comes into engagement with the force transmission element 9 of the actuating element 4.
  • Characterized the locking element 6 is adjusted in the direction of a blocking position, as shown in Fig. 2.
  • a stop 10 of the adjusting element 4 which is provided here by the power transmission element 9, with a counter-stop 11 of the locking element 6 in blocking engagement, whereby the further adjustment of the adjusting element 4 is blocked.
  • the force transmission element 9 releases the driver 8.
  • the blocking element 6, driven by its bias falls in the direction of the starting position with its counter stop 11 on the stop 10 of the adjusting element 4 in a catching position (not shown). By catch position ensures that the actuator 4 can come regardless of its movement speed with the blocking element 6 in blocking engagement.
  • the stop 10 of the adjusting element 4 for realizing the catching position lies in the path of movement of the counter-stop 11 of the blocking element 6.
  • FIG. 3 corresponds to the time of the setting cycle in which the driver 8 is just released.
  • the there drawn circle section 5a about the pivot axis 5 of the locking element 6 shows the path of movement of an edge of the counter-stop 11 on the locking element 6, which intersects the stop 10 on the adjusting element 4, which forms the prerequisite for the above fishing position.
  • An actuating cycle of the actuating element 4 is connected to the blocking of the actuating element 4 with the adjustment of the actuating element 4 in a rotational direction. Switching the drive motor 2 to another direction of rotation is not necessary in this respect.
  • a torque monitor preferably in the form of a current monitoring of the electric drive motor 2 and / or by a timer, the time, however, must be sufficiently long, so that the blocking position actually achieved.
  • a further adjustment of the adjusting element 4 during the setting cycle preferably causes the blocking element 6 to pivot into the blocking position.
  • the stop 10 may have a run-on slope 12 and the counter-stop 11 a corresponding, further run-on slope 13.
  • the stop 10 or only the counter-stop 11 such a stop bevel 12, 13 has (Fig. 1, 2, 3), or that the pivoting of the locking element 6 is otherwise realized in the blocking position.
  • the catching position itself is the blocking position and, accordingly, further pivoting of the blocking element 6 out of the catching position is not necessary at all.
  • the locking member 6 When the locking member 6 is in the blocking position and the drive motor 2 is turned off, a provision of the locking element 6 is connected in the direction of its initial position with a slight return of the actuating element 4 against the original direction of movement, so that the locking element 6 finally unhindered in its initial position can swing.
  • the stop 10 and the counter-stop 11 or one of these two elements preferably in turn have corresponding run-on slopes 12, 13.
  • the actuator 4 is then not designed to be self-locking, so as not to hinder the provision.
  • the provision of the locking element 6 and the associated slight return of the adjusting element 4 is here and preferably effected by the bias of the locking element 6 in its initial position.
  • the power transmission element 9 of the actuating element 4 as already mentioned at the same time the stop 10 of the actuating element 4. This allows a particularly simple and inexpensive production of the actuating element 4.
  • the power transmission element 9 is preferably designed as a pin. However, it can also be configured as a contour or the like.
  • the axis of rotation 3 of the adjusting element 4 and the pivot axis 5 of the locking element 6 are arranged parallel to each other and spaced from each other. This allows a simple and flat construction, which is advantageous in terms of the necessary space.
  • the blocking element 6 is pivotable here and preferably out of its initial position in two pivoting directions. It has a blocking position in both pivoting directions.
  • the adjusting element 4 is accordingly bidirectionally adjustable, so that the adjusting element 4 can be blocked in both directions of movement by the blocking element 6.
  • the blocking element 6 is pivotable out of its initial position in only one pivoting direction.
  • this embodiment is preferred because it is correspondingly more compact.
  • the blocking element 6 is designed here as a lever with a longitudinal axis.
  • the driver 8 is arranged on the longitudinal axis between the counter-stop 11 and the pivot axis 5 (Fig. 1, 2, 3).
  • the locking element 6 is designed symmetrically with respect to its longitudinal axis. This allows in particular a simple embodiment of the two blocking positions for the different pivot directions.
  • the adjusting element 4 is preferably designed symmetrically with respect to a symmetry line intersecting its axis of rotation 3. This is particularly advantageous in connection with the above symmetrical blocking element 6 and the bidirectional activation of the adjusting element 4.
  • the counter-stop 11 of the locking element 6 is preferably designed as a substantially V-shaped catching pocket, which is formed from the run-on slopes 13 ( Figure 1).
  • the opening of the catching pocket is aligned towards the driver 8, so that the power transmission element 9 runs from the catching position starting with further adjustment of the adjusting element 4 in the catching bag.
  • the control element 4 has two power transmission elements 9 in the preferred exemplary embodiment shown in FIGS. 1, 2, 3.
  • the power transmission elements 9 are arranged offset by approximately 180 ° with respect to the axis of rotation 3 of the actuating element 4 against each other. Accordingly, shorter movements of the actuating element 4 are required for the actuation or the activation of functions, as would be the case with only one force transmission element 9. Depending on the application, more than two power transmission elements 9 may be provided.
  • the blocking element 6 is preferably arranged so that the longitudinal axis of the blocking element 6 intersects the axis of rotation 3 of the adjusting element 4 in its initial position. This too is advantageous in terms of symmetry and in particular in the case of two blocking positions. Furthermore, the blocking element 6 is configured and arranged such that its counter-stop 11 is not in the movement path of the actuating element 4 when the locking element 6 is in the starting position. The movement of the actuating element 4 can thus be carried out unhindered by the blocking element 6 until the driver 8 engages with the force transmission element 9.
  • Fig. 4 shows a second embodiment for which apply substantially the above explanations to the first embodiment. Shown is the actuator 1 in befindlichem in blocking position blocking element 6 and in blokkiertm actuator. 4
  • Fig. 4 can be removed that the counter-stop 11 of the locking element 6 is not in registration with the adjusting element 4, as long as the locking element 6 is in its initial position. This is particularly advantageous because it reduces the risk of obstruction of other functions.
  • the power transmission element 9 of the actuating element 4 is designed as a control contour.
  • the locking element 6 has a first and a second counter-stop 11, which a first and a second stop 10 are assigned to the actuator 4.
  • the stop 10 of the adjusting element 4 is arranged as far as possible with respect to the axis of rotation 3 of the adjusting element 4 to realize the lowest possible impact force.
  • the stop 10 is arranged in the outer third of the adjusting element 4.
  • the power transmission element 9 is on the other hand with respect to the axis of rotation 3 of the actuating element 4 as far as possible inside, preferably in the inner third of the actuating element 4, respectively. This allows a high translation between actuator 4 and locking element 6, so that a correspondingly low torque on the adjusting element 4 for the adjustment of the locking element 6 is required. This shows the particular advantage of the spatial separation of power transmission element 9 and stop 10, namely the requirement-based interpretation of these two components.
  • the adjusting element 4 and the locking element 6 are preferably arranged so that the blocking force between the stop 10 and counter-stop 11 causes a compressive load in the locking element 6. This is particularly favorable with regard to the material load in the area of stop 10 and counter stop 11.
  • the actuator 1 also has a damper 14 for the locking element 6 in the respective blocking position (FIG. 4).
  • the damper 14 is configured and arranged so that the adjustment of the locking element 6 is in any case attenuated acoustically in the blocking position.
  • the damper 14 is used here for noise reduction.
  • FIGS. 5, 6, 7 show a further exemplary embodiment which, although following the same principle as described above, in which the blocking element 6 is not symmetrical in contrast to the previous embodiments. The above description applies accordingly for this embodiment. It should be noted that, in particular in Figs. 5, 6, 7 to is a rough schematic representation, which can not be found for the function, if necessary, necessary proportions.
  • the blocking element 6 has a plurality of drivers 8, here exactly two drivers 8a, b, as well as two counterstops 11a, b.
  • Each counter-stop 11a, b is associated with one of the drivers 8a, b, and each of the counter-stops 11a, b is associated with a direction of movement of the adjusting element 4.
  • Fig. 6 shows the locking element 6 in the first blocking position, which is achieved in that the adjusting element 4 is rotated from the starting position (Fig. 5) to the right.
  • the power transmission element 9 initially passes the driver 8b under a short and functionless pivoting of the locking element 6 in the drawing on the right. Subsequently, the power transmission element 9 comes into engagement with the driver 8a, and presses the locking element 6 in the direction of the first blocking position.
  • the force transmission element 9 releases the driver 8a and the blocking element 6 falls with its counter-stop 11a on the stop 10 of the actuating element 4, wherein the stopper 10 is provided by the force transmission element 9 as in the first embodiment.
  • the adjusting element 4 is now blocked directly or, as described above, after a slight further adjustment.
  • the locking element 6 has a recess 15 which is shaped and is arranged, that the locking element 6 is independent of the storage of the adjusting element 3 on the axis of rotation 3 of the adjusting element 4 away until it reaches the corresponding blocking position is pivotally.
  • the actuator 4 via a speed reduction with another actuator (not shown).
  • the further control element then serves to deliver the actuating movements of the actuator 1.
  • a reduction of, for example, 3: 1 three revolutions of the actuating element 4 are necessary to achieve a revolution of the other control element.
  • the embodiments shown in FIGS. 1 to 4 thus require six actuating cycles with always the same direction of rotation for a full revolution of the other control element.
  • the originally two approachable positions of the actuating element 4 have been transferred to six positions of the other control element. It may be pointed out that this multiplication of positions to be approached is possible in that with the actuator 1 according to the invention successive actuating cycles in the same direction of rotation of the actuating element 4 are possible.
  • the actuator 1 basically the actuating movements of the control element 4 are used to control the respective function. Then, the actuator 4 is coupled with transmission elements, not shown here for forwarding the actuating movements. Alternatively or additionally, it may be provided that the adjustment of the locking element 6 is used as an adjusting movement in the above sense. As a result, this can lead to a particularly high functional density.
  • the adjusting element 4 is assigned a further blocking element.
  • the adjusting element 4 then has for engagement with the further blocking element at least one further force transmission element and a further stop.
  • the force transmission element forms the stop.
  • the two blocking elements are preferably arranged on opposite sides of the adjusting element 4.
  • the actuator 1 is suitable here in a special way as part of a motor vehicle lock. Further, it is preferred that the motor vehicle lock a lock mechanism with multiple functional states, such. B. theft-proof, child-resistant, normally secured, has unlocked and that the lock mechanism by means of the control element 4 in one or more functional states can be switched.
