Definitions
- the invention relates to a motor vehicle lock having a locking mechanism with a rotary latch and at least one pawl, a release lever for unlocking the locking mechanism, an electrically operable locking and unlocking device and an electrically operable child safety device.
- Today's motor vehicles are equipped with a number of security functions that secure a vehicle against unauthorized access, protect children from accidents and/or have an anti-theft device. All of these security systems are implemented in the motor vehicle lock and presented to the operator of the motor vehicle as functions. When leaving a motor vehicle, the doors and/or flaps are usually locked, so that actuation of the outside door handle, for example, is ineffective and opening of a side door, for example, can be prevented.
- the motor vehicle lock can contain a child safety device, which is preferably set up on the rear doors.
- a one-stroke or two-stroke actuation can also be implemented in the motor vehicle lock, for example to release a lock.
- a lock override
- a lock can be overridden with a single actuation of the inside actuation lever, a The closed position of a bolted and childproof door can thus be changed so that it can be opened using an outside door handle.
- an override function there is the possibility that a locked and childproof motor vehicle lock is unlocked by pulling the inside operating lever. If, for example, the motor vehicle lock is locked and the childproof lock is engaged, then the locking of the outside actuating lever can be released by pulling on the inside actuating lever. There is thus the possibility that the motor vehicle lock can be opened from the outside.
- a motor vehicle lock has become known from DE 20 2012 003 171 U1, in which an unlocking of a motor vehicle lock can be transferred into an unlocked position by actuating the inside actuating lever. With two consecutive actuating movements of the inside actuating lever, there is thus the possibility of first releasing the locking and then unlocking the locked locking mechanism. With this two-stroke movement, it is therefore possible to lift a lock manually.
- the publication describes a child safety device with which unlocking of an interior control can be prevented.
- a motor vehicle lock according to the invention is preferably a door lock, more preferably a side door lock, but can be used wherever components that are movably arranged on the motor vehicle have to be secured. Mention should be made here, for example, of hood locks, sliding door locks, locks for covers or flaps, tailgates or doors, precisely all of these components which must be held securely in position when the motor vehicle is used or which include safety-related functions.
- the locking mechanism has a rotary latch which can be held in at least one latching position, the main latching position, by means of a pawl.
- locking mechanisms are also used that are equipped with a main locking position and a pre-locking position, as prescribed, for example, in side doors.
- the locking mechanism can also be equipped with a pawl or, for example, with a pawl and a blocking lever.
- a blocking lever is used when in at least one latching position, preferably the main latching position, an opening moment occurs in the locking mechanism, with the opening moment initiating an independent opening of the locking mechanism and with the independent opening NEN can be prevented by means of the blocking lever.
- the invention is therefore not limited to a special locking mechanism.
- Locking devices are used to interrupt the operating chain from, for example, an outside door handle via a Bowden cable, for example, to an outside operating lever and finally to the release lever.
- the locking devices interrupt the actuating chain from the outside door handle to the locking mechanism, so that unlocking of the locking mechanism is prevented when the motor vehicle lock is in the locked state.
- the locking device acts electromechanically, with an electric motor being provided which actuates the locking device and interrupts the actuating chain.
- the locking and unlocking device can be actuated by means of a worm gear
- an advantageous embodiment of the motor vehicle lock can be provided.
- the use of a worm gear makes it possible to realize quick actuations in the shortest possible time and thus to be able to insert the most diverse switching and functional positions in the motor vehicle lock.
- the worm gear consists of an electric motor with a worm arranged on the output shaft of the electric motor, the worm interacting with a worm wheel which in turn actuates the locking and unlocking lever.
- a switching means can be arranged on the worm wheel so that a locking and unlocking position can be reliably detected.
- the worm gear thus has a dual function, on the one hand the locking and unlocking lever can be actuated by means of the worm gear and on the other hand a control contour on the worm gear can interact with a switching means.
- the worm wheel has another function that comes into play in relation to an override function of the motor vehicle lock.
- the worm wheel also has a stop surface, it being possible for the stop surface to engage with the inside actuating lever.
- a locking lever is provided and a torsion spring is attached to the locking lever, at least one spring leg of the torsion spring having a clutch lever for the external actuation interacts, this results in a further embodiment variant of the invention.
- the locking lever itself interacts with the worm wheel and is actuated by means of the worm wheel of the worm gear.
- the locking lever is pivotally accommodated in the motor vehicle housing.
- a torsion spring is attached to the locking lever itself in such a way that one leg of the torsion spring is firmly connected to the locking lever and another leg of the torsion spring projects beyond the dimensions of the locking lever and is operatively connected to a clutch lever.
- the clutch lever By actuating the locking lever, the clutch lever is deflected in such a way that actuating the external actuating lever runs idle. In other words, the connection between the external operating lever and the release lever is broken.
- the free leg of the leg spring is in contact with the clutch lever and pivots the clutch lever in such a way that the outside actuating lever cannot actuate the release lever.
- the actuation chain can be interrupted in the direction of external actuation, and the motor vehicle lock can thus be locked.
- the locked position is consequently held by the clutch lever, which is deflected under spring tension.
- the child safety device has a driver and the clutch lever can be brought into engagement with the driver. Due to the structure according to the invention and the interaction of the driver, ie the child safety device with the clutch lever, an anti-theft device can be provided with existing structural means.
- the clutch lever acts as a locking element
- the driver of the child safety device can act as a stop surface, resulting in a position or orientation of the clutch lever on the one hand determinable and on the other hand fixable.
- the driver is part of the child safety device and is also driven by an electric motor.
- a worm gear preferably acts on the child safety device, with the worm gear actuating the driver and actuating a further clutch lever on the release lever.
- the driver has a stop surface that can be brought into engagement with a contour on the clutch lever.
- the carrier as part of the child safety device serves as a stop surface or fixing surface for the clutch lever.
- a contour is provided on the clutch lever, which can be brought into engagement with the stop surface.
- the contour is designed in such a way that a form-fitting engagement with the stop surface is made possible.
- the clutch lever can be fixed by means of the driver, with the clutch lever being spring-loaded in an initial position.
- the clutch lever can be fixed by means of the driver, i.e. it can be held in the correct position. If the clutch lever is actuated and transferred to the locked position, the clutch lever comes into engagement with the housing in an end position. If the driver is now then pushed through the child If the safety drive moves, the stop surface on the driver engages with the contour on the clutch lever in such a way that the clutch lever is fixed between the housing and the stop surface. Movement of the clutch lever is prevented until the driver is actuated again and the child safety device is disengaged.
- the clutch lever and the further clutch lever are preferably pivotably mounted on the release lever. This offers the advantage that further bearing points in the motor vehicle lock can be dispensed with and a structurally favorable structure can be achieved.
- the driver can be guided by means of the housing, that the housing has a guide or at least one guide surface or a stop for the driver, so that the child-proof position can be reached safely.
- the object of the invention is achieved in that a method for inserting an anti-theft device in a motor vehicle lock is provided in which a locking device is first inserted in an electrically actuated manner, with a clutch lever being transferred to a locked position and then a driver of a child safety device is actuated electrically, as a result of which the clutch lever is transferred into a fixed position.
- the motor vehicle lock described above can additionally provide anti-theft protection with existing structural means.
- only two electric drives can be provided, on the one hand for the locking and on the other hand for the child safety device, while a controlled and staggered actuation of the electric drives enables the clutch lever to be fixed and thus theft protection to be secured.
- a functional expansion of an existing lock can thus be implemented with minimal design means.
- FIG. 1 shows a plan view of an opened motor vehicle lock, only the components necessary for explaining the invention being reproduced and the motor vehicle lock being in an unlocked and non-actuated position
- FIG. 2 shows the motor vehicle lock constructed according to the invention according to FIG. 1 in a locked state
- FIG. 3 shows the motor vehicle lock according to the invention in a locked position with the anti-theft device inserted
- FIG. 4 shows the motor vehicle lock according to the invention in the locked position with the child safety device engaged and the possibility of an override function.
- FIG. 1 shows a motor vehicle lock 1 in a top view of the release, locking and security mechanism. Shown is an external actuating lever 2, a release lever 3, an internal actuating lever 4, a locking lever 5 and an electric motor 6 for actuating the locking lever 5 and a further electric motor 7 for actuating a driver 8.
- the driver acts on a clutch Development lever 9 for the inside operating lever 4, the clutch lever 9 being mounted on the release lever 3 in an axis 10.
- a further clutch lever 11 for the external actuating lever 2 is accommodated on the release lever 3 , again pivotably mounted on an axis 12 .
- the motor vehicle lock 1 is shown in an unactuated and unlocked position. In this position it is possible, by actuating the outside actuating lever 2 in the direction of the arrow P1, to take the release lever 3 with it via the clutch lever 11, the clutch lever 11 likewise pivoting about the axis 13 in the clockwise direction.
- the release lever 3 comes into engagement with the locking mechanism with a stop surface 14 so that the locking mechanism (not shown) can be unlocked.
- a torsion spring 15 is arranged on the inside activation lever 4, which moves the inside activation lever 4 back into the starting position.
- the external actuating lever 2 is also spring-loaded and can be returned to its starting position shown in FIG. 1 by means of a spring element.
- a torsion spring 16 is fastened to the locking lever 5 , with a spring arm or spring leg 17 being in engagement with the clutch lever 11 of the external actuating lever 2 .
- the vehicle lock 1 is in the position shown in FIG. 1 in the non-actuated state and is unlocked.
- FIG. 2 now shows the motor vehicle lock 1 in a locked position.
- the electric motor 6 is energized, as a result of which a worm 18 can be driven on an output shaft 19 of the electric motor 6.
- the worm 18 interacts with a worm wheel 20, whereby actuation of the electric motor 6 for locking the motor vehicle lock 1 actuates the worm wheel 20 in a clockwise direction, as a result of which the locking lever 5 is moved in a counterclockwise direction.
- the spring leg 17 pivots the coupling lever 11 as a result of the rotary movement of the locking lever 5, the coupling lever 11 being pivoted clockwise about its axis 12.
- the motor vehicle lock 1 can still be unlocked via the inside operating lever 4 and the operating lever chain of the inside operating lever 4, the clutch lever 9 and the release lever 3, so that an operation, for example of an inside door handle and thus an operation of the inside operating lever 4, is possible Unlocking the locking mechanism and thus opening a side door, for example, is made possible.
- FIG. 3 now shows the locked and theft-proof state of the motor vehicle lock 1.
- the motor vehicle lock 1 is still in a locked position, as described in FIG.
- the worm 24 was now actuated via the additional electric motor 7 and the worm wheel 25 was moved clockwise about the axis 26 .
- the rotary movement of the worm wheel 25 moved the driver 8 in the direction of the arrow P4, as a result of which the clutch lever 9 was also moved, namely pivoted about the axis 10.
- the clutch lever 9 By actuating the driver 8, the clutch lever 9 reaches a position in which an actuation of the inside actuating lever 4 in a clockwise direction goes idle.
- the release lever 3 cannot be actuated either by actuating the external actuating lever 2 or by actuating the internal actuating lever 4 .
- FIG. 3a shows a section through the driver 8 on the clutch lever 11 in the area of the arrow III.
- the clutch lever 11 was moved into the locked position by means of the spring arm 17. lung transferred.
- a stop surface 26 on the driver 8 has come into engagement with a contour 27 on the clutch lever 11 .
- the clutch lever 11 is thus fixed in position and cannot be moved.
- Neither actuation of the external actuating lever 2 nor actuation of the internal actuating lever 4 makes it possible here to unlock the motor vehicle lock 1 . Any movement of the outside operation lever 2 and the inside operation lever 4 is idle.
- the fixing by the coupling lever 11 also prevents the lock from being unlocked by the electric motor 6 . Unlocking with the inside operating lever 4 using the override function is also excluded.
- the locked and childproof mode of the motor vehicle lock 1 is now shown in FIG. To achieve this state, starting from FIG. 1, ie the non-actuated and unlocked state, the driver 8 was first moved in the direction of the arrow P4. The driver 8 is moved as described above via the electric motor 7, the worm 24 and the worm wheel 25. By moving the driver 8, the stop surface 26 reaches the position shown in FIG. 3a and FIG. 4a. After the driver 8 has been moved, the electric motor 6 is now energized and the locking lever 5 is actuated via the worm 19 and the worm wheel 20, as a result of which the spring arm 17 has in turn pivoted the clutch lever 11 clockwise.
- the pivoting of the clutch lever 11 has the result that the contour 27 against the stop surface 26 reached, the clutch lever 11 only being able to be pivoted against the stop surface 26 .
- the clutch lever 11 is thus in the locked position, but is not fixed in its position by the stop surface 26 . Rather, the contour 27 rests against the stop surface 26 in a spring-loaded manner.
- override In contrast to the position of the clutch lever 11 in FIG. 3, an override can now take place according to the position of the clutch lever 11 in FIG.
- override means that actuating the inside actuating lever 4 can activate the outside actuating lever 2 . If the inside actuating lever 4 is now pivoted in the starting position according to FIG 1 position shown is pivoted. The pivoting of the worm wheel 20 has the effect that the locking lever 5 is also turned clockwise, and at the same time the torsion spring 16 or the spring arm 17 releases the clutch lever 11 .
- the locking state of the external actuating lever 2 can also be controlled selectively by means of the electric motor 6 . Thus, a locked external control lever 2 can be activated while driving (Speed Lock) independently of the child safety device.
- the clutch lever 11 is spring-loaded and also returns to the starting position shown in FIG. Pulling on the inside actuating lever thus unlocks the motor vehicle lock 1. It is now possible to actuate the release lever 3 by actuating the outside actuating lever 2 and to unlock a locked locking mechanism.
- This override function makes it possible for a person in the vehicle to actuate the inside actuating lever 4 and to unlock the motor vehicle lock 1 . In this state, a person outside the motor vehicle can then unlock and thus open a side door of a motor vehicle, for example, by operating the outside door handle. A child sitting inside the motor vehicle, for example, can unlock the motor vehicle lock, but the child safety device remains engaged.
- an override function can be implemented in the motor vehicle lock 1 in the simplest of constructions and in interaction with the components located in the motor vehicle lock 1 .
