Definitions
- the invention relates to a motor vehicle lock, in particular a motor vehicle door lock, with a locking mechanism consisting essentially of a rotary latch and a pawl, and with an electric motor drive with an electric motor, the electric motor drive being selectively “coupled” and “engaged” in the positions by means of an actuating element, a coupling element of an actuating lever chain “disengaged”.
- Motor vehicle locks and in particular motor vehicle door locks of the design described above are used in different variants and in a variety of positions in and on a motor vehicle. In fact, this includes, among other things, tailgate locks, front hood locks, fuel filler flap locks and also seat locks. In general, however, the relevant motor vehicle locks and in particular motor vehicle door locks are implemented on motor vehicle side doors.
- TCR temporary crash redundancy
- the operating lever chain in question is generally open and therefore “locked” during normal operation, so that the locking mechanism cannot be acted upon using the operating lever chain during normal operation. Rather, in such a case, the electric motor drive ensures the electric motor opening.
- the coupling element generally ensures this. In such a case, this is transferred to its “engaged” position, which corresponds to the closed design of the operating lever chain. As a result, arriving rescue personnel can, for example, open the locking mechanism mechanically via the operating lever chain that is closed in this way. If, on the other hand, in normal operation the coupling element is “disengaged” and the actuating lever chain is therefore “locked”, the actuating lever chain cannot be caused to open the locking mechanism when it is acted upon.
- the invention is based on the technical problem of achieving a structural simplification compared to the prior art and, in particular, of creating the possibility of equipping the electric motor drive for additional functions in addition to acting on the coupling element.
- a generic motor vehicle lock and in particular a motor vehicle door lock within the scope of the invention is characterized in that the actuating element is assigned a blocking element, which is used for a temporary blocking of the actuating element to switch off the electric motor after an actuator has moved and then reversing the actuating element and thus the electromotive opening drive.
- the implemented blocking element makes it possible to easily distinguish and separate individual functional states and corresponding actuator movements that can be achieved with the help of the electric motor drive.
- the motor vehicle lock in question generally and during normal operation assumes a locked state in which the associated operating lever chain is opened.
- the actuating element ensures that the coupling element of the actuating lever chain assumes its “disengaged” position.
- the operating lever chain is open.
- unlocking is generally required first.
- the actuating element may be acted upon by the electric motor drive starting from a basic position or ensures this Spring, with the help of which the actuating element is pretensioned in the “unlocked” direction of the operating lever chain.
- an actuator movement can now be carried out to open the locking mechanism using an electric motor.
- This can be achieved, for example, by the signal from a sensor, which informs a control unit acting on the electric motor drive that the actuating element and thus the actuating lever chain have assumed their “unlocked” position.
- the sensor in question can also be assigned to the coupling element, which was transferred from its functional position “disengaged” to the “engaged” position during normal operation.
- the locking mechanism is now opened by an electric motor.
- the electric drive with electric motor usually acts on the actuating element in the opposite direction compared to the operating direction that was used to assume the “unlocked” position.
- This control element movement of the electric motor drive with electric motor and consequently also of the control element is continued until the additionally provided blocking element ensures the temporary blockage of the control element.
- the blocking of the adjusting element by the blocking element which generally interacts directly with the adjusting element, ensures that the adjusting element is held and blocked.
- the electric motor acting on the actuating element which consequently experiences a blockage or "blocks".
- the electric motor or the control unit is typically assigned a sensor system which, for example, detects an increased current consumption of the electric motor during such a block run, this process leads to the Blocking the control element by the incoming blocking element results in the electric motor being switched off.
- a spring assigned to the electric motor drive can ensure that the actuating element is reversed and at the same time the blocking element swings out in comparison to its blocking position or leaves the blocking position.
- the electric motor drive returns to its basic position.
- the blocking of the control element is temporary, i.e. H. temporary, namely only as long as the blocking element is in its blocking position compared to the actuating element.
- the coupling element When the actuating element moves to open the locking mechanism using an electric motor in the example case, the coupling element is generally and at the same time acted upon with the help of the actuating element and goes from its “engaged” position to the “disengaged” position again. As a result, at the end of the actuator travel, the actuating lever chain returns to the “locked” position it already occupied at the beginning.
- the interaction between the actuating element and the blocking element enables perfect functional separation when acting on the actuating element, on the one hand, to unlock the actuating lever chain and, on the other hand, to open it by electric motor. All of this is achieved while taking into account a simple and compact structure, because only the actuating element and the blocking element interact with each other. This is where the main advantages can be seen.
- the blocking element as well as the adjusting element are each mounted rotatably about an associated axis. Both axes are predominantly arranged parallel to one another and spaced apart from one another.
- the topological design is correctly chosen so that the blocking element is adjacent to a blocking contour of the Actuating element is arranged.
- the blocking element is generally designed as a blocking lever with at least a blocking arm and a control arm.
- the blocking arm advantageously has a pin that interacts with a contour of the adjusting element. Due to the interaction between the pin and the contour, the blocking lever or the blocking element can interact directly with the actuating element or its contour in order to be able to ensure the previously described temporary blocking of the actuating element to switch off the electric motor.
- the contour in question is usually designed as a U-shaped web.
- the pin arranged on the blocking arm of the blocking lever can pivot into the U-shaped web in question via an opening in the U-shaped web to temporarily block the actuating element.
- a corner of the U-shaped web usually ensures that the actuating element is temporarily blocked when the pin is in contact with it in order to switch off the electric motor.
- Fig. 1 shows the motor vehicle lock according to the invention in the form of a
- FIG. 1 shows the functional state “TCR off” of the electromotive drive 8, 9, 10.
- the electromotive drive 8, 9, 10 acts on the coupling element 7 against the force of the associated spring.
- the actuating lever chain 3, 4, 5, 6, 7 is in its “locked” position and the coupling element 7 assumes its functional position “disengaged”.
- the transmission lever 6 counteracts the force of the spring acting on the coupling element 7, thus ensuring that that the coupling element 7 assumes its retracted position shown in FIG Empty movement relative to the release lever 3 is completed.
- a priority of unlocking which can be understood in the transition from FIG. 2A to FIG. 2B, now corresponds to the fact that the actuating element 10, starting from the functional position in FIG. 2A, carries out a counterclockwise movement indicated in FIG. 2B.
- the blocking lever 11 pivots in the direction of the actuating element 10.
- the blocking element 11 according to the exemplary embodiment is used as a blocking lever at least one blocking arm 11 a and one control arm 11 b are formed.
- a spring arm 11 c is also implemented, on which a spring 12 and in particular a tilting spring 12 acts.
- the blocking element 11 is designed as a three-armed blocking lever 11.
- the actuating element 10 may in turn and generally be acted upon by the force of a spring in the unlocking direction or - as in the exemplary embodiment - by a corresponding current supply to the electric motor 8 as part of the electric motor drive 8, 9, 10.
- the blocking contour 14 is a U-shaped web into which the pin 13 pivots via an opening 15 to temporarily block the adjusting element 10. It can be seen that the blocking element 11 is arranged overall adjacent to the blocking contour 14 or the U-shaped web 14.
- FIGS. 2D and 3A that after reaching the “unlocked” position in FIG. Because a counterclockwise movement of the actuating element 10 starting in the starting position according to FIG is pivoted in the clockwise direction indicated in FIG. 1 in order to be able to open the locking mechanism 1, 2.
- the actuating element 10 can no longer be pivoted any further counterclockwise about its axis using the electric motor drive 8, 9, 10 and the actuating element 10 is blocked.
- Such a blockage of the actuating element 10 is accompanied by an increased current increase to act on the electric motor 8, which can be detected by the control unit, which is not expressly shown, for example. This increase in current is interpreted as a blockage of the electric motor 8 and causes the electric motor 8 to be switched off.
- the actuating element 10 can now be acted upon using the spring 16 already mentioned, in the sense of a pivoting movement in the clockwise direction about its axis, as indicated in FIG. 4 and an arrow there. Because the electric motor 8 or the electric motor drive 8, 9, 10 is switched off and can no longer act on the actuating element 10, so that it can be pivoted more or less freely and only acted upon by the spring 12, namely in the clockwise direction.
- control element 10 has been temporarily blocked, namely when the pin 13 dips into the corner of the U-shaped web 14 on the control element 10 and at this point for the temporary, i.e. H. time-limited, blockage of the actuating element 10 and consequently the electric motor 8 ensures.
