Definitions

  • the invention relates to a motor vehicle lock, in particular a motor vehicle door lock, with a locking mechanism consisting essentially of rotary latch and locking pawl, further with an actuating lever chain for the locking mechanism, further with a locking element and at least one securing element, and with exactly one with both the locking element and the locking element also the safety element interacting spring element, the actuating lever chain via the locking element at least in the functional states “unlocked” and “locked” and additionally via the safety element in the functional states “unlocked” and “secured” controllable.
  • motor vehicle lock includes not only motor vehicle door locks and, in particular, motor vehicle side door locks. But this generally also includes motor vehicle locksmiths for front hoods, patch flaps, sliding doors, tank lids, loading flaps etc.
  • the locking element can in principle be a central locking element. With its help, the operating lever chain can be transferred to the functional states “unlocked” and "locked”.
  • the functional state "unlocked” usually corresponds to the fact that the lock can be opened via the operating lever chain.
  • the functional state “locked” belongs to the situation that in general it is not possible to open the locking mechanism from the outside using the operating lever chain, but it is still permitted from the inside.
  • the securing element additionally provided can generally be a child safety element or an anti-theft element or both.
  • the functional state “unlocked” belongs to the situation that the (rear) motor vehicle side door in question can be opened from the inside, even if for example, the locking element is in the “locked” state.
  • the “secured” state corresponds to the fact that the motor vehicle door in question cannot be opened from the inside.
  • the functional state “unlocked” corresponds to the fact that, as a rule, the associated motor vehicle door can be opened both from the inside and from the outside.
  • the functional state “secured” is part of the fact that the motor vehicle door cannot be opened from the inside or the outside, so that the associated motor vehicle lock cannot be opened even if, for example, the window of the motor vehicle door is smashed.
  • Both the locking element and the securing element can be inserted by motor or drive technology as well as manually or by hand.
  • a child safety nut is known, with the help of which the various functional states can be set manually.
  • the change in the functional state of the locking element or central locking element usually takes place by means of a motor or drive technology.
  • a spring can take on a wide variety of functions.
  • DE 10 2017 124 530 A1 of the applicant describes a motor vehicle door lock which is equipped with a first and second pawl.
  • the first pawl is acted upon by a spring with the interposition of an actuating lever.
  • the spring has two spring legs extending from a leg base, one spring leg resting against the actuating lever in question, while the other spring leg resting against the further second pawl. Due to the specific design, the teaching described above has not significantly influenced the present problems of safely taking and maintaining the functional states of both the locking element and the securing element.
  • the further prior art according to DE 101 57 473 A1 concerns a drive unit for a door lock, in which an engagement part in the form of a spring is provided on a toothed wheel or a cam.
  • the engagement part or the leaf spring implemented at this point can be brought into engagement with an unlocking mechanism when a locking mechanism is in the initial state.
  • the leaf spring in question thus takes on a force-transmitting function and is not used to change or secure position.
  • the invention is based on the technical problem of developing such a motor vehicle lock and in particular motor vehicle door lock so that the various functional states of the operating lever chain are safely and over the entire temperature range that can be covered, taking into account a structurally simple design.
  • a generic motor vehicle lock and in particular motor vehicle door lock is characterized within the scope of the invention in that the (exactly one) spring element interacts not only with the locking element and the securing element but also with the actuating lever chain.
  • the spring element thus has a triple function. So the spring element interacts not only with the locking element and the securing element. Instead, according to the invention, a further third interaction occurs with the actuating lever chain.
  • the spring element in connection with the locking element and the securing element generally ensures that at this point a position securing of the relevant element (securing element and spring element) is achieved and can be made available.
  • the additional interaction of the (single) spring element with the actuating lever chain is designed in such a way that with the aid of the spring element, for example, an actuating lever as part of the actuating lever chain is reset after its deflection.
  • a (single) spring element provides, within the scope of the invention, on the one hand for securing the position of both the securing element and the locking element.
  • the spring element additionally ensures that the actuating lever in question or the actuating lever chain as a whole is moved back into its initial position after its deflection, for example to act on the locking mechanism.
  • the spring element assumes a restoring function, whereas the interaction with the respective element (securing element or locking element) takes place in the sense of securing the position. This is where the main advantages can be seen.
  • the spring element is connected to an actuating lever of the actuating lever chain.
  • the spring element is usually designed as a leg spring.
  • the leg spring has a leg base to which two spring legs are connected. If the spring element is coupled to the actuating lever of the actuating lever chain, the leg base ensures that the spring element is connected to the actuating lever with its help.
  • the leg base usually surrounds a bearing section of the actuating lever.
  • the invention is based on the knowledge that the actuating lever is usually rotatably mounted around a bearing pin in a lock case or a lock housing.
  • the bearing bolt in question is surrounded by the leg base of the spring element, so that in this way the bearing bolt also ensures that the spring element is fixed.
  • the leg spring not only has the leg base connected to the actuating lever, but also the two spring legs extending from the leg base.
  • the design is advantageously made such that the spring element rests with its one lever spring leg against a stop of the actuating lever. Acting upon the actuating lever in the sense of a pivoting movement about its bearing pin consequently leads to the lever-spring leg in question being deflected. After the application of the actuating lever has ended consequently the deflected lever spring leg ensure that the actuating lever is pivoted back into its starting position. That is, the lever spring leg takes over the previously mentioned restoring function of the spring element.
  • the spring element or its other element spring leg is now designed according to the invention and advantageously such that said element spring leg interacts and can interact with both the locking element and the securing element. That is, the element spring leg is used in this context to secure the respective position of the associated and respective element, that is, both the locking element and the securing element.
  • the element spring leg is usually equipped with two lugs as part of the spring element.
  • the design is also made in such a way that the respective nose interacts with an associated cam on the respective element to secure its position. According to an advantageous embodiment, this takes place in such a way that the respective functional state of the element belongs to a position of the associated cam on this side and on the other side of the corresponding nose. That is to say, the “locked” functional state of the locking element may correspond, for example, to a position of the cam on the locking element on this side of the associated nose of the element spring leg. Logically, the complementary functional state “unlocked” of the locking element belongs to the position of the cam on the other side of the associated nose.
  • a change between the two functional states is possible without any problems in that the cam on the element in question pushes the nose back against the force of the element spring leg and is transferred from its position on this side of the nose to the position on the other side of the nose and vice versa. This means that two bistable functional states of the respective element are secured with the aid of the element spring leg.
  • This securing can take place in addition to securing, for example, a drive for the element in question, which for this purpose may be equipped with a self-locking mechanism.
  • a drive for the element in question which for this purpose may be equipped with a self-locking mechanism.
  • the associated functional state is in any case made available and guaranteed with the aid of the element spring leg or the combined effect of the associated nose on the element spring leg with the corresponding cam on the element.
  • the respective element can be equipped with a tooth segment.
  • the element in question can come into engagement with an associated drive via the toothed segment.
  • an associated drive via the toothed segment.
  • the securing element can be equipped with a toothed segment for driving the securing element via an associated motor.
  • the respective element can also be equipped with an actuating arm.
  • the respective element can be actuated manually via this actuating arm.
  • the actuating arm is acted upon with the aid of a drive in order to ultimately implement a respective Drehbe impact on the associated element when changing between its two functional states.
  • a motor vehicle lock and in particular a motor vehicle door lock, is made available which first of all ensures that the two functional states of both the locking element and the securing element are correctly assumed, permanently and even at different and, in particular, low temperatures.
  • the motor vehicle lock according to the invention works with a (single) spring element, which serves both to secure the position of the locking element and of the securing element.
  • the spring element in question then functions as a return spring for the actuating lever chain or an actuating lever as part of the actuating lever chain. This doesn't just make one constructively simple solution provided. Instead, the use of a (single) spring element at this point also ensures a particularly inexpensive implementation. This is where the main advantages can be seen.
  • a motor vehicle lock and in particular a motor vehicle door lock is shown.
  • this has a locking mechanism (not shown in detail) consisting of a rotary latch and pawl and an operating lever chain 1, 4.
  • the operating lever chain 1, 4, according to the exemplary embodiment and for the sake of clarity, is based on an external operating lever 1 and a release lever to be described in more detail below 4 reduced.
  • the external actuation lever 1 is mounted in a lock housing 3 such that it can rotate about an axis 2.
  • the release lever 4 is also rotatably mounted in the lock housing 3 in question about the same axis 2.
  • the external actuation lever 1 and the release lever 4 can be quasi-rigidly connected to one another in its “coupled” state via a coupling lever 5 which is only partially recognizable.
  • a coupling lever 5 which is only partially recognizable.
  • the locking element 6 is used to move the coupling lever 5 into its “engaged” and “disengaged” positions.
  • the first-mentioned state corresponds to the functional position “unlocked” (FIG. 1A) of the locking element 6, whereas the second-mentioned state “off coupled” of the coupling lever 5 corresponds to the functional position “locked” (FIG. 2) of the locking element 6.
  • the clutch lever 5 is only shown in the front view of FIG. 1A.
  • the rear view of FIG. 1B and the other FIGS. 2 to 4 corresponds to this.
  • the “unlocked” state is now shown in solid lines and belongs to the “engaged” position of the clutch lever 5.
  • the “locked” state which belongs to the “disengaged” state of the clutch lever 5, is shown in dash-dotted lines.
  • the external actuation lever 1 and the release lever 4 are quasi-rigidly coupled to one another via the coupling lever 5, so that an actuation of the external actuation lever 1 in the indicated counterclockwise direction corresponds to the release lever 4 being external actuating lever 1 follows in the counterclockwise direction about the common axis 2 during its movement.
  • a stop 4a on the release lever 4 can move against the pawl, not shown in detail, which is thereby lifted from its engagement with the rotary latch, so that a locking bolt previously caught by the locking mechanism is released.
  • the associated motor vehicle door can be opened (see FIG. 1A).
  • the figures also show a securing element 8, which, within the scope of the exemplary embodiment and not by way of limitation, is a anti-theft element 8 or a child safety element.
  • the safety element 8 is mounted about an axis 9 comparable to the locking element 6 pivotable with respect to the lock housing 3.
  • the locking element 6 has an actuating arm 6a on which a drive 10, which is only indicated, can act and ensures that the locking element 6 is pivoted about the axis 7 when its respective functional state changes.
