Definitions

  • the invention relates to a lock for a motor vehicle having a locking mechanism consisting of a rotary latch and at least one pawl, a closing device, an electric drive and a torque converter, a variable torque being adjustable in the closing device by means of the torque converter, and the closing at least in some areas by means of a frictional connection (K) is achievable.
  • the DE 101 40 365 A1 a servo lock holder for a motor vehicle door lock, the term "servo lock holder” being used for a lock holder in which an automatic closing takes place.
  • a locking bolt of the motor vehicle door lock is attached to an adjustable actuating oscillator.
  • a drive for the actuating oscillator is provided. The drive transfers the actuating oscillator with the locking bolt as well as a rotary latch comprising the locking bolt and consequently an associated door from a pre-latching position into a Main notch position motorized.
  • An additional locking lever ensures that the actuating rocker is held in this position when the door is manually transferred from the pre-locked position to the main locked position.
  • Such lock holders provided with a closing device are basically used for all conceivable doors on a motor vehicle. For example, it is conceivable not only to act on side doors, but also on trunk flaps, tailgates or engine hoods and is also included within the scope of the invention. With the aid of the closing device implemented in this way, the door or vehicle door in question can now be shifted from the previously mentioned pre-locking position into a main locking position against the resistance of, for example, a seal.
  • a closing device is the subject of DE 198 28 040 B4 .
  • This is a power-assisted locking device for doors, flaps, tops or roofs of motor vehicles and in particular passenger cars, in which a pivotable stop element is arranged on a rotary latch.
  • the pawl interacting with the rotary latch also has a pivotable stop element.
  • the two stop elements interact with a control disk during the opening or closing process.
  • the control disk is part of an actuator, with the help of which both an opening and a closing process can be effected.
  • a rotary latch is moved from a pre-locking position to a main locking position by means of a closing or drive pawl and with the aid of a Bowden cable with a separate external drive.
  • the closing device has a Bowden cable which is connected to a torque converter via a cam disk.
  • an electric drive engages a gearwheel by means of a worm wheel, for example, the gearwheel additionally having a cam disk.
  • the Bowden cable is connected to the cam in such a way that a torque dependent on the drive path can be generated.
  • a progressively increasing torque is preferably achieved, so that a tightening torque that is different depending on the position of the cam disk can be provided on the rotary latch.
  • the torque converter thus generates a force dependent on the drive path, the closing force necessary for closing, that is to say transferring the catch from a pre-catch position into a main catch position. This is advantageous, for example, because when transferring the rotary latch from the pre-latching position into the main latching position, the rotary latch must be moved against a sealing pressure from a door seal, for example.
  • the object of the invention is to provide an improved lock for a motor vehicle.
  • the object of the invention is achieved in that a lock is provided for a motor vehicle, having a locking mechanism consisting of a rotary latch and at least one pawl, a closing device, an electric drive and a torque converter, with a variable torque in the closing device is adjustable and wherein the closing can be achieved at least in some areas by means of a frictional connection, characterized according to the invention in that in a first closing movement of the rotary latch the closing device introduces a closing torque by means of a frictional connection into the rotary latch, and that in a second closing movement of the rotary latch the closing device applies a closing torque introduced into the rotary latch by means of a form fit.
  • the force in the form of a frictional connection which is transmitted at least in some areas during the closing, now creates the possibility of larger closing paths for a motor vehicle or a movable one arranged on the motor vehicle Component can be carried out automatically without any safety risk for the operator.
  • a safety risk arises when a component that is movably arranged on the motor vehicle is moved by means of an electric drive, as a result of which an operator can become trapped.
  • Various locks and actuating elements can be used as a lock for a motor vehicle.
  • the lock can be used as a compact unit, for example in a side door, sliding door or in the area of flaps or lids or covers.
  • hood locks, auxiliary locks such as in vans, are used.
  • a locking mechanism in a motor vehicle lock has a rotary latch and at least one locking pawl, the rotary latch being able to be held in a locked position by means of the locking pawl.
  • Two-stage locking mechanisms consisting of a preliminary detent and a main detent as well as systems with one or two locking pawls are used.
  • a release lever acts on the locking mechanism, whereby the release lever disengages the one or more pawls, for example by a pivoting movement with the locking trap.
  • the release lever is preferably pivotably mounted in the motor vehicle lock and preferably in a housing and / or a lock case of the motor vehicle lock.
  • the closing device has an electric motor drive and works together with a torque converter.
  • the electric drive with the torque converter can be arranged directly in the lock or can interact directly or indirectly with the rotary latch as a separate module, for example by means of a Bowden cable.
  • the Bowden cable core can then, for example, be connected to a closing pawl, wherein the closing pawl can act directly on the rotary latch.
  • the closing pawl is then arranged pivotably in the lock, specifically in such a way that the closing pawl can be brought into engagement with the rotary latch via the closing path.
  • the closing device is integrated directly on the lock or even in the lock.
  • the electric drive and the torque converter for example in the form of a gear, are directly connected to the rotary latch.
  • an electric motor can interact with a spindle drive, the spindle drive moving the closing pawl.
  • the closing pawl can be arranged pivotably in the lock such that the closing pawl can be brought into engagement with the rotary latch via the closing path.
  • a transmission or a mechanism, with which at least different forces or torques can be introduced into the rotary latch, can serve as the torque converter.
  • the torque converter makes it possible to generate a torque that can be changed at least in some areas, that is to say via the closing path is, so that the rotary latch can be acted upon with different forces or moments.
  • the closing takes place at least in areas by means of a force fit.
  • the closing mechanism is designed such that a releasable connection can be established between, for example, a closing pawl and the rotary latch.
  • a connection can be established between the closing pawl and the rotary latch, which connection can be prevented.
  • the frictional connection when pulling the rotary latch can be overcome by an operator of the motor vehicle manually grasping a door or flap and thus overcoming the frictional connection, whereby a closing can be interrupted.
  • a coat or a hand can be in the area of the door or flap and this means for preventing then prevents further closing by overcoming the frictional connection and the closing process can be interrupted. Only when a form fit has occurred between the rotary latch and the closing device in a second area of the closing movement can the closing movement no longer be interrupted. An easily interruptible closing is thus made possible in the first area, whereas in the second area the form fit allows for closing is made possible or is possible against the force of a door or flap seal, for example.
  • the closing pawl can also be brought into engagement with the rotary latch when the rotary latch has not yet reached a locking position.
  • the door or flap or sliding door would only be ajar, but not yet engaged with the lock of the lock. This makes it possible to move the rotary latch over a large area and thus also to close the door or flap over a large area of closing by means of the closing device.
  • the closing device can have a closing pawl, wherein the closing pawl can be brought into engagement with the rotary latch.
  • the closing device can have a Bowden cable and / or a transmission.
  • the closing pawl offering a structurally simple possibility to produce a frictional connection on the one hand and a positive connection between the closing pawl and rotary latch on the other hand.
  • the frictional connection can be established by a connection between the electric motor drive and the gearbox and a Bowden cable.
  • the connection between the Bowden cable or Bowden cable core and gearbox can be designed in such a way that there is a force fit over a first closing area, i.e. a first closing movement, whereas a form fit between the gearbox and Bowden cable core is present over a second closing area or the second part of the closing movement can be produced.
  • the frictional connection in the closing device can be generated by means of the Bowden cable and / or by means of the transmission and / or by means of the closing pawl be. Achieving the frictional connection in the closing device is therefore not tied to the combination of means, but can also be achieved from a combination of the components present in the closing device or in the lock.
  • the transmission for example, there can be a slip clutch
  • the Bowden cable can be driven via a semi-locking connection
  • the closing pawl can be designed, for example, in such a way that there is only a frictional connection between the closing pawl and the rotary latch via a first closing path.
  • the combination of frictional engagement and positive engagement then makes it possible in the closing device that on the one hand a force fit and on the other hand a positive fit can be produced.
  • the tightening torque in the first tightening movement is less than the tightening torque in the second tightening movement.
  • the division of the closing movement and an adaptation of the transferable forces or moments in the different movements of the closing device makes it possible here that a closing can be prevented even with low forces.
  • the door can then be pulled shut by means of a very small torque, which means that an operator of the motor vehicle, including a child, is able to do so with very little force to prevent or stop the closing movement in the first part of the closing process. If the closing movement is interrupted in the first part of the closing movement, the closing device disengages, the frictional connection is overcome and the door and / or flap can be opened.
  • a closing force of approx. 100 Newtons can be generated by means of the closing device in the first closing movement and a closing force of approx. 500 Newtons can be generated in a second closing movement or can be provided by means of the closing device.
  • a low force for closing during the force-fit transmission of the force in the closing device enables the closing process to be easily interrupted, for example a child's hand. Trapping during the closing and in particular during the first part of the closing movement can thus be guaranteed.
  • the very low forces of 80 to around 120 Newtons make it possible that a door or flap can be moved, but the closing movement can easily be interrupted. Only in the second part of the closing movement is a high force of around 500 Newtons pulled or a torque introduced into the rotary latch, so that the force of a door or flap seal, for example, enables the door to be safely closed and transferred to a main locking position.
  • a closing movement of the rotary latch can be initiated when the rotary latch engages in a lock holder, which represents a further embodiment of the invention.
  • the closing movement is generated by means of the closing device and the rotary latch, independently of the respective latching position. If the rotary latch thus comes into operative connection with the lock holder, the lock holder bolt or a striker, a closing movement of the door or flap can be initiated or initialized by means of the rotary latch. If the rotary latch is already driven by an electric motor or driven indirectly by means of the closing device at this point in time, a closing movement can be driven by an electric motor, that is to say automatically, over a very wide closing area of the door. In this case, the closing movement is not linked to reaching a latching position, that is to say a preliminary latching position or a main latching position of the locking mechanism, but can be initialized by means of the rotary latch when the lock holder is reached.
  • first closing movement can be carried out from reaching an engagement of the rotary latch in a lock holder up to a closed position of 4 mm. Pulling shut from the engagement of the rotary latch in the lock holder to a position in which the door or flap is already closed to within 4 mm offers maximum security.
  • first closing movement there is only a frictional connection, so that up to a closing area of 4 mm the Closing movement is interruptible. Only when the closed position is 4 mm does the form fit take effect in the second closing movement. 4 mm form a gap on the door or flap, which prevents intervention, for example with a hand or a finger.
  • the gap size with regard to reaching the rotary latch in the engagement area with the lock holder can be variable and is different depending on the design of the motor vehicle.
  • the engagement of the rotary latch engages with a gap dimension of 25 mm, preferably 20 mm and even more preferably 15 mm and very particularly preferably with a gap dimension of 10 mm.
  • the first closing movement can therefore close gaps of more or less than 20 mm by means of a force-fit movement without a safety risk for the operator occurring.
  • the inventive design of the closing device also enables a structurally favorable and cost-effective solution to the closing, since largely identical components can be used, with only structural changes to existing components having to be changed in part and depending on the embodiment.
  • the lock has a sensor for detecting a position of the locking mechanism and a control for the closing device, at least one means for detecting a position of a component that can be moved by means of the closing device being provided and the means for detecting the control interacts. Due to the interaction between the means for detecting a position of the component to be moved in combination with the closing device, the control is able to detect the position of the component with a precise position. In particular, this makes it possible to interrupt the movement that has been initiated into the component by means of the closing device at any time. The control is thus able to interrupt the closing process independently of the position of the component during the engagement with the closing device.
  • the closing process can be interrupted in that a current of the closing device is interrupted, for example by ejecting an engaged closing pawl and / or interrupted by reversing the closing process. This can prevent an operator from being trapped, for example.
  • Various locks and actuating elements can be used as a lock for a motor vehicle.
  • the lock can be used as a compact unit, for example in a side door, sliding door or in the area of flaps or lids or covers.
  • hood locks, auxiliary locks such as, for example, in vans are used.
  • the closing takes place with constant detection of the movement of the component, the means for detecting the control transmitting a signal so that the position of the component or the position of the part of the motor vehicle that is drawn by means of the component can be determined at any point in time of the closing.
  • the closing device is a locking device of a motor vehicle with which a side door of a motor vehicle is drawn, then the position of the door and thus the gap size during the closing can be determined by means of the means for detecting.
  • the gap between the moving door and the body is determined here.
  • the gap determines in particular the area which is open for a hand of an operator, for example, between the movable component, preferably the door, and the body when the door is closed.
  • the means for detection is a sensor or a switching means, in particular a microswitch.
  • a rotary sensor for example, which records the rotary movement of the moving component, in particular the rotary latch, can be used as the means for detection.
  • one, two or more microswitches can also be used, which individually and / or in combination detect the movement and thus make it possible to determine the movement of the component and thus the door or flap, for example, moved by means of the component. The movement of the door or flap itself can also be recorded, so that the positions can be determined in combination with the control unit.
  • Microswitches are inexpensive, whereas rotary sensors enable a very precise determination of a moving component and its position.
  • the closing process is only monitored in certain areas, namely when only areas of the gap dimension need to be monitored.
  • the closing pawl only falls into the component to be moved in a range of ⁇ 10 mm, preferably ⁇ 8 mm and even more preferably 6 mm.
  • the closing process must therefore first be monitored. From a gap dimension of ⁇ 4 mm, it is no longer possible for an operator to use his fingers, for example, to get into the gap between the door and the body, for example.
  • the area ⁇ 4 mm can then be excluded from monitoring, for example.
  • a monitoring of the gap size of 10-4 mm, preferably 8-4 mm and even more preferably 6-4 mm is viewed as an advantageous embodiment.
  • the means for detecting a position interacts with the controller in such a way that the closing process can be interrupted by detecting an increase in current in the electric drive.
  • an increase in current indicates that the closing process is subject to great stress.
  • the control system evaluates this increase in current, in this way the control can determine whether the deviation of the current increase is such that the current increase lies outside a tolerance window so that the closing process can be interrupted. If the closing drive acts, for example, on a locking mechanism of a lock in a side door of a motor vehicle, then the door reaches, for example, a main notch of the locking mechanism of the side door lock.
  • the closing process now begins, that is to say, for example, a closing pawl comes into engagement with the rotary latch and moves the rotary latch in such a way that the rotary latch can be transferred from a preliminary latching position into a main latching position.
  • the closing device must move the door against the door seal, so that a greater force has to be used to close the door as the closed position increases and the gap size decreases.
  • the force can be determined within a tolerance range, so that deviations outside the tolerance range or a predefinable tolerance window can be detected and the control is able to interrupt the closing process, eject the closing pawl if necessary and / or initiate reversing the closing process.
  • the increase in current can thus be used advantageously as a safety measure when pulling in.
  • the movable component is a door, a flap, a cover or a hood of a motor vehicle.
  • the movable component is moved by means of the closing device, the component also clinging to the motor vehicle or the body in such a way that there is no gap or only very small gaps.
  • the gap dimensions are kept as small as possible or, for example, in the case of a convertible roof cover, a secure closure is effected.
  • the closing device interacts directly with the locking mechanism or a tether, this results in a further advantageous embodiment.
  • the closing takes place depending on the point of application of the closing device in such a way that the components, such as flaps, lids or doors, are transferred from a first closed position to a second closed position. If, for example, a locking mechanism of a motor vehicle lock is pulled, the door or flap can be moved from a pre-locking position of the locking mechanism to a main locking position. If the closing device engages the limiting strap, it is also possible to move or close the door or flap over a wider area. During the closing, it is continuously monitored whether the closing and in particular the power consumption of the drive is within the tolerance range or tolerance window of the power consumption, in order to be able to draw conclusions about a possible hazard for an operator.
  • the rotary latch can be moved by means of the closing device, a further advantageous embodiment variant results.
  • the rotary latch can be moved in such a way that, for example, a closing pawl comes into engagement with the rotary latch in a force-fitting and / or form-fitting manner. If the rotary latch is moved by means of the closing device and, for example, by means of a closing pawl, the rotary latch engaged with the lock holder can move the door or flap or seat from a first engagement position in the lock holder to the main locking position or an overstroke position. If excessive power consumption is detected on the drive during the closing process, the closing process can be interrupted. This training can thus provide a maximum of security. Trapping or injury when tightening can thus be prevented.
  • the means for detecting the position is arranged on the rotary latch.
  • the sensor means can act directly on the rotary latch, so that monitoring is carried out very precisely and over the closing area which is important for an operator of the motor vehicle. In particular, the area of the tightening, which can lead to injury or trapping, is of interest.
  • querying the position of the rotary latch a very precise monitoring of the gap size or a conclusion about the gap size is possible, since the engagement relationships between the rotary latch and lock holder can be related to the gap size of the door very precisely.
  • a further embodiment is obtained when a variable closing torque can be provided by means of the closing device.
  • the controller can control a changing closing torque, with a tolerance window being monitored at any point in time so that the current cannot deviate beyond the tolerance window without the control generating at least a warning signal or the closing process interrupts, disengages the closing or reverses the closing process. The operator can thus be prevented from being trapped in any way and the operator cannot be injured.
