Definitions

  • a motor vehicle lock according to the preamble of independent claim 1 has a lock cover and a locking mechanism consisting essentially of a rotary latch and at least one pawl and also at least one coupling element and at least one electric drive, wherein the coupling element can assume different positions and the coupling element with a drive element of the drive and a central locking mechanism, the coupling element being connected to the drive element to assume its positions.
  • a motor vehicle lock of the type described above is usually attached to a motor vehicle door on the one hand and interacts with a locking bolt on the body side.
  • the arrangement can also be reversed, so that the locking bolt is arranged on the motor vehicle door and the lock is arranged on the motor vehicle side.
  • Such motor vehicle locks are equipped with a central locking mechanism and usually have different positions and associated functions. It is conceivable that the positions of the coupling element can be adjusted via the drive.
  • Such motor vehicle locks are, for example, from DE 199 43483B4 known.
  • an anti-theft module and, on the other hand, a locking module are implemented.
  • a motor vehicle lock in particular a motor vehicle lock for a vehicle rear door, known, with a lock cover and a locking mechanism consisting essentially of a rotary latch and at least one pawl, further with at least one coupling element, with at least one electric drive, wherein the coupling element can assume different positions and the coupling element interacts with a drive element of the drive and a central locking mechanism, the coupling element being connected to the drive element to assume its positions, the drive element and/or the lock cover having a locking contour with at least two position indentations and being provided with a spring mechanism, the spring mechanism being connected to the Position indentations of the locking contour cooperate, whereby the coupling element can be positioned in the positions.
  • the present invention is therefore based on the technical task of at least partially eliminating the disadvantages known from the prior art.
  • the object of the present invention is to provide a motor vehicle lock in a cost-effective and structurally advantageous manner, in which positioning of the coupling element can be ensured.
  • the motor vehicle lock in particular a motor vehicle lock for a vehicle rear door, has a lock cover and a locking mechanism, the locking mechanism essentially comprising a rotary latch and at least one pawl. Furthermore, the motor vehicle lock has at least one coupling element and at least one electric drive, wherein the coupling element can assume different positions and the coupling element interacts with a drive element of the drive and a central locking mechanism, wherein the coupling element is connected to the drive element to assume the positions.
  • the drive element and/or the lock cover have a latching contour with at least two position indentations, a spring mechanism being provided and the spring mechanism interacting with the position indentations of the latching contour in such a way that the coupling element can be positioned in the different positions.
  • the coupling element is rotatably mounted on a bearing holder on the drive element.
  • the bearing holder is arranged on the back of the locking contour.
  • the bearing holder can be designed as a hole on the drive element or on the coupling element, with the drive element and the coupling element being connected to one another via a bearing pin or bolt.
  • An advantage of the invention is that the drive element and/or the lock cover have a latching contour and interact with the spring mechanism in such a way that the coupling element can be reliably positioned or fixed in the various positions.
  • the spring mechanism accordingly acts via a spring force on the locking contour, in particular in the position indentations of the locking contour, such that the drive element is held in the various positions by the spring force of the spring mechanism. Accordingly, a position determination or positioning can be established there.
  • the positions can also be referred to as functional positions. It is conceivable that a first position is defined by the functional position “child safety lock inserted/can be released”. In this functional position, the child safety lock is engaged, but can be released/disengaged by repeatedly pressing an interior door operating element. A second position can be defined with the functional position “childproof designed”. A possible third position can be defined by the functional position “child safety designed”. Alternatively or additionally, the functional position “central locking inserted”, “central locking disengaged” and/or “anti-theft device inserted” and “anti-theft deterrent designed” can also be present. If child locks are referred to below, this can also be used as an alternative or in addition to an anti-theft device and/or central locking, so that child locks are used as a synonym for the functions of child locks, anti-theft locks and central locking.
  • a motor vehicle lock can, in addition to a lock housing, also have a lock case and a lock cover, with the help of which the Lock case can be locked.
  • the locking mechanism is stored in the lock case, which consists of a rotary latch and at least one pawl that interacts with it.
  • the rotary latch and consequently the motor vehicle door lock defined in this way interacts with the locking bolt in a known manner.
  • the lock housing can be arranged on the body side or on the hood or door side.
  • the lock housing is mounted on a vehicle body, for example by screws.
  • the variant mentioned in a second place corresponds to the lock housing and with it the door lock being attached inside or on a door, a hood, a flap or the like.
  • motor vehicle lock When speaking of a motor vehicle lock in the context of the invention, this includes motor vehicle locks that are used, for example, in side doors, sliding doors, flaps, hoods and/or covers, precisely where pivotally or displaceably mounted components are arranged on the motor vehicle. It is also conceivable to arrange a motor vehicle lock in a backrest of a seat.
  • the coupling element according to the invention is preferably rotatably arranged on the drive element of the drive.
  • the drive element can now be designed to be rotatable about an axis, the drive element being able to be rotated about the axis of rotation into the various positions via the drive. Accordingly, the coupling element connected to the drive element is moved into the different positions.
  • the drive element can be controlled mechanically and/or electrically into the different positions, with the respective position change taking place either purely mechanically or purely electrically.
  • motor vehicle side doors and consequently the associated motor vehicle door locks can be moved into different positions or
  • the unlocked position of the motor vehicle lock and consequently also the functional position of the associated motor vehicle door correspond to the fact that the motor vehicle door can be opened independently of one another by acting on both an outer door operating element and the inner door operating element.
  • the position or functional position on the rear motor vehicle side doors can also be child-proofed.
  • an associated interior door operating element becomes inoperable, so that the motor vehicle side door in question cannot be opened when an occupant operates the interior operating element.
  • the outside door handle is still in engagement with the locking mechanism, so that the motor vehicle side door in question can be opened from the outside.
  • Another functional position or position can be described as anti-theft, with both the outer door handle and the inner door handle remaining in the non-functional position in the anti-theft position. In this way it is ensured that a motor vehicle door does not provide access to the interior of the motor vehicle even when the motor vehicle window is broken.
  • a spring mechanism which interacts with the position indentations of the locking contour of the drive element or the lock cover.
  • One or more spring elements can be provided.
  • Another advantage of the design according to the invention is that less installation space is required and the spring can be designed more simply. This results from the fact that the spring mechanism interacts directly with the position indentations of the locking contour and the spring force acts on the position indentations of the locking contour via clear and definable or calculable force vectors. Because the spring mechanism interacts with the position indentations, installation space can be saved and the spring can be designed better because there is no angular play. The angular play is essentially saved or prevented by the design of the spring mechanism and the position indentations.
  • the first clutch element according to the invention can be designed, for example, as a clutch lever.
  • a second coupling element can be designed as an external locking lever.
  • the spring mechanism according to the invention is designed as a torsion spring, in particular a double torsion spring.
  • a leg spring enables a cost-effective design of a motor vehicle lock, while at the same time sufficient spring force can be provided for the positioning of the drive element and thus the coupling element.
  • the leg spring in particular the double leg spring, makes it possible to exert a direct force transmission on the position indentations of the locking contour.
  • the spring mechanism is preferably arranged on the lock housing or the lock case or lock cover and interacts with the position indentations of the locking contour of the drive element or the lock cover.

  • the spring mechanism in particular the double leg spring, can be arranged on the lock cover, on the coupling element or on the drive element, with a winding section of the spring mechanism being able to be brought into contact at least with the position indentations of the locking contour for position fixing.
  • the winding section of the spring mechanism has at least one contact point with the position indentations of the locking contour. Due to the torsional spring force of the spring, the winding section is always pressed onto the locking contour or the position indentations of the locking contour on the drive element.
  • the spring is always pretensioned by its bearing points, so that there is no angular play between the drive element and the spring mechanism.
  • the torsion spring preferably has about one to about 15 turns, preferably between about 5 turns and about 10 turns.
  • the spring mechanism has a compression spring or is designed as a compression spring and is arranged on the drive element, the compression spring being able to be brought into contact at least in sections with the position indentations on the lock cover, whereby the different positions are held.
  • the spring mechanism has steel and/or plastic. The compression spring thus makes it possible to transmit the force directly to the position indentations of the locking contour of the drive element or the lock cover.

  • the positioning element can preferably be pin-shaped and/or spherical.
  • the positioning element is arranged and guided at least in sections in the spring receptacle. Accordingly, the positioning element is arranged at one end of the compression spring.

  • the drive element can advantageously be designed as a worm wheel and have an external toothing section which can be brought into engagement with the electric drive.
  • the external toothing section can be brought into engagement with a worm of the electric drive.
  • the drive element is designed with external teeth and is rotatably arranged on the lock cover or lock housing via a bearing.
  • the drive element designed as a worm wheel preferably has a plastic.
  • the external toothing section and the locking contour, in particular the position indentations, are preferably arranged on the drive element diametrically opposite the external toothing section.
  • the external toothing section is formed on the circumference of the drive element on a first level and the locking contour is formed on at least a second level. This has the advantage that the angle of rotation can be increased and more positions can be implemented. On different levels this means that several levels or stages can be formed along the axis of rotation of the drive element.
  • the locking contour can be essentially wave-shaped or essentially V-shaped and each position indentation can have at least one, preferably two contact surfaces with which the winding section of the spring mechanism, in particular the double leg spring, can be brought into contact, in particular, the contact surface being designed to be essentially rectilinear .
  • the locking contour and thus the position indentation are concave on the drive element or the lock cover.
  • the concavely shaped curves as position indentations of the locking contour are semicircular, essentially creating a wave geometry.
  • the position indentations and the winding section of the spring mechanism thus have at least two contact points with one another, in which force is transmitted from the spring mechanism to the locking contour.
  • each position indentation has at least one, preferably two, rectilinear contact surfaces against which the winding section of the spring mechanism rests.
  • the outer sections of the essentially semicircular position indentations are therefore straight and no longer arcuate. Accordingly, there is a combination of wave-shaped and V-shaped design of the position indentations. Considering the position indentation as in Essentially U-shaped, the legs no longer have any rounding towards the outside. Rather, the legs are designed as a straight line towards the end.
  • the spring mechanism in particular the double leg spring, has at least two fastening ends, with each fastening end being arranged in a respective fastening receptacle, in particular in a respective elongated hole.
  • the fastening receptacle is preferably formed in the lock cover or the drive element.
  • the elongated hole thus enables the fastening ends of the double leg spring to move in the elongated hole when a double leg spring is deformed.
  • fastening the fastening ends in the fastening receptacles, in particular in the elongated hole enables a defined force transmission from the spring mechanism to the locking contour and thus the position indentations.
  • a play compensation can also be adjusted via the attachment, in particular in at least one elongated hole of one attachment end of the spring mechanism.
