Definitions
- the invention relates to an electromotive actuator for a motor vehicle lock - Side door lock, rear door lock, hood lock - with the features the preamble of claim 1.
- a motor vehicle lock of the type in question regularly has one Lock mechanics that are switched to different functional states should, for example, in the functional states “unlocked”, “locked”, “locked-theft-proof”, “childproof” and possibly also “open by wire “(opening aid) or” servo closing ".
- the electric drive motor with a Worm gear coupled, the worm wheel of which forms the control element.
- a driver on the worm wheel which is the switching element is capable of knocking over the pivoting lever between two positions.
- the electric drive motor is controlled by block operation, namely in that the driver on the control element in each of the two possible positions of the pivoting lever forming the switching element a stop surface lying transverse to the direction of movement of the driver starts. This blocks the further movement of the control element, the current that the electric drive motor draws suddenly increases, this is evaluated in terms of circuitry and the drive motor is switched off.
- the shutdown in block mode can also be controlled by a timer, a torque detection or the like.
- the locking stop on the locking element has a non-locking starting position and a blocking blocking position, in which it is in the movement path of the Power transmission element is on the actuator.
- switch-off position without using a switch.
- This switch-off position is thus in block mode and therefore practically tolerance-free realized.
- the switch-off position can be added to the corresponding one Realize switch-off positions in the end positions of the switching element, but you can also completely dispense with end positions of the switching element and only realize free switch-off positions.
- only one direction of rotation can be provided for the control element or provide a drive in both directions of rotation.
- the power transmission element in each the directions of rotation act so that a corresponding in each direction Switch-off position is realized.
- Fig. 1 shows based on the prior art, from which the teaching of the present Invention starts (DE - A - 44 39 479), the basic structure of such an electromotive actuator for a motor vehicle lock.
- Such an electromotive actuator is in most cases a central locking drive that moves the lock mechanism into the various Functional states, ie the functional states "unlocked”, “locked”, “Theft-proof”, “Child-proof” and possibly also the functional states “open by wire” and / or "locking aid” (special case).
- the basic principle of such an electromotive actuator is for Motor vehicle lock always about positioning the control element as precisely as possible, thus desired switch-off positions with the smallest possible tolerance to reach.
- the lock mechanism is an actuator for a motor vehicle lock of the motor vehicle lock not shown.
- A is shown electric drive motor 1 and one of the drive motor 1 via a non self - locking gear, here a worm gear with worm 2 and Worm gear 3, driven actuator 4, which in the illustrated embodiment is coupled to the worm wheel 3.
- a switching element 5 is driven, which in the illustrated embodiment is designed as a swivel lever and for switching the lock mechanism 6 serves in the different functional states.
- FIG. 1 shows on actuator 4, a driver 7, which on a circulation sheet in .both directions of rotation is movable.
- the driver 7 forms together with the control element 4 a kind of crank mechanism.
- the illustrated embodiment shows that both end positions of the Switching element 5 forming pivot lever by a mechanical block Define switch-off positions of the electric drive motor 1 because namely the driver 7 here at right angles to the direction of movement of the driver 7 stops 8 and the drive motor 1 outgoing drive train blocked with it.
- the teaching of the invention is now concerned with how to turn off positions of the control element 4 in a simple, robust manner and precisely set and start can, as is the case for mechanical positions Block can realize.
- Fig. 2 shows a starting position of an electromotive according to the invention Actuator. This can be the position that corresponds to an end position of the Switching element 5 corresponds. When realizing the invention it will rather a normal switch-off position approached according to the invention.
- the actuator 4 is a movable locking element 10 associated with a locking stop 11 for has the power transmission element 9.
- the power transmission element 9 of the moving control element 4 meets the locking stop according to the invention 11 of the locking element 10, in such a way that thereby the movement of the actuator 4 blocked and the drive motor 1 by this mechanical Block is switched off.
- the switch-off takes place as already in general Part of the description explained by overcurrent detection, if necessary also by a time switch, that is simply by the expiry of a predetermined Follow-up time, through torque detection etc., all procedures that in the State of the art for this are known.
- FIGS. 2 to 5 makes it clear that it is provided here that the moving actuator 4 during movement in the direction of the locking stop 11 itself the locking stop 11 in the movement path of the force transmission element 9 on the actuating element 4 relocated.
- the locking element 10 has a drive stop 12, on which the power transmission element 9 first to System comes to shift the locking element 10 so that the locking stop 11 reaches the path of movement of the force transmission element 9.
- the Return spring 13 is designed as a leg spring with a spring stop 14 on the locking element 10 and a fixed spring stop 15, the So practically arranged on the housing of the electromotive actuator is cooperating.
- the return spring 13 as a leg spring wraps around a sleeve on the pivot axis 16 of the here as a pivot lever executed locking element 10.
- other types of reset elements instead of a return spring 13, for example magnets or the like can optionally be used.
- Fig. 2 shows a power transmission element 9 on the actuator 4.
- Fig. 3 is however indicated that there is another force transmission element on the actuating element 4 9 is located. Since this is only optional, this is Power transmission element on the control element 4 on the right only in thin dashed lines Lines drawn.
- the two power transmission elements 9 would be in this variant offset by approximately 180 ° on the control element 4 arranged. That would mean that not a switch-off position, but approached two switch-off positions per revolution of the control element 4 become.
- the actuator 4 also in two opposite to each other Directions of movement could run, then in both directions of movement a shutdown would take place at the stop 11.
- the Locking stop 11 shows this by its central position and in both directions acting return spring 13, which is both a deflection after allowed on the left as well as on the right in the same way.
- the drive stop too 12 is designed symmetrically and makes it clear that it acts in both directions of rotation of the control element 4.
- the worm gear from worm 2 and worm wheel 3 in the shown Embodiment is not self-locking, leaves immediately after switching off of the electric drive motor 1, the pressure of the power transmission element 1 to the stop 11 after.
- the spring force is sufficient the return spring 13, the locking element 10 in its initial position swing back, which it then reaches again in Fig. 5 of the drawing Has.
- the control element 4 is exactly in the switch-off position defined by the stop 11 stopped. From the position shown in Fig. 5, the actuator 4 can triggering the electric drive motor 1 again into the next switch-off position, for example an end position of the switching element 5, or, preferably, a further switch-off position can be moved.
- FIGS. 2 to 5 shows an embodiment of the electromotive actuator according to the invention, in which the locking element 10 is pivoted from the actuator 4 into the blocking position, just before the power transmission element 9 hits the locking stop 11.
- the locking element 10 is pivoted from the actuator 4 into the blocking position, just before the power transmission element 9 hits the locking stop 11.
- the embodiment shown in Fig. 6 shows another special feature.
- the driver 7 could Omit control element 4 and another control element shown in FIG. 6 18 assign that with the actuator 4 including a certain Reduction is coupled.
- the actuator 4 including a certain Reduction is coupled.
- the control element 4 would make three turns, while the second actuator 18 makes one revolution. That in turn would mean that through the locking element 10 and the locking stop 11 defined switch-off position is reached three times, while the second Control element 18 has completely rotated once.
- the actuating element 4 is linear Actuator slide executed. You can see that here instead of one Worm gear provided gear that rotates transmits the electric drive motor 1 to a threaded spindle 20 which runs the actuator slide forming the actuator 4. Not shown is the switching element 5, which is moved by the control element 4. It can be in on another level.
