Definitions

  • the invention relates to a locking device according to the preamble of claim 1.
  • the invention further relates to a method for closing the locking device.
  • a lock of a locking device of the type mentioned is used for temporary closure of openings in motor vehicles or buildings by means of doors or flaps. In the closed state of such a lock, the rotary latch engages with two arms (called load arm and tentacle) around a particular bow-shaped locking bolt around.
  • the locking bolt may be attached in the case of a motor vehicle to a door or flap of the motor vehicle and then the lock on the body or vice versa.
  • the present invention is particularly advantageous for front hoods or front flaps, which are seen in the usual direction of travel of a motor vehicle front.
  • the lock regularly includes a lock case or a lock plate and a lock cover, with the aid of the lock case is closed. Lock case and lock cover are called lock case.
  • the locking mechanism, so catch and pawl are basically rotatably mounted on the lock case. For reasons of stability lock case, catch and / or Pawl advantageous metal.
  • the lock lid is, inter alia, for reasons of weight advantageously made of plastic.
  • a lock plate or lock case basically comprise an inlet region for the locking pin. It is an example, U-shaped bulge, which allows the locking pin to fall into the catch.
  • the lock housing can be arranged on the body side or hood or door side.
  • the lock housing is fixed to a motor vehicle body, for example, by screws.
  • the variant mentioned in the second corresponds to the fact that the lock housing and with it the door lock is mounted inside or on a door, a hood, a flap or the like.
  • a locking device particularly preferably comprises such a motor vehicle lock.
  • the lock housing is regularly mounted on the body side, so it is found on an associated vehicle body.
  • the locking bolt is connected to a hood, so that usually a hood lock or bonnet lock is considered. In principle, however, the procedure can also be reversed. Then the locking bolt is connected to the body or vehicle body, whereas the lock housing and with it the motor vehicle lock learns an attachment to the hood or the door generally.
  • the catch of such a lock starting from an open position by pivoting a closed position, the catch is finally locked by means of the pawl.
  • Such pivoting is achieved by the locking bolt (also called “lock retainer”) when it engages by closing an associated door or flap in the catch.
  • a locking surface of the pawl is in the locked state of a locking surface of the rotary latch, thereby preventing that the catch can be turned back in the open position.
  • the locking pin can not leave the locking mechanism in the closed position.
  • Such a lock may include an electric drive to move a rusted in the pre-locking position locking in the main detent position, to finally the Lock catch in the main ratchet position.
  • Such a lock is also called lock with closing aid.
  • a lock with closing aid is from the DE 10 2009 026 921 A1 known.
  • the DE 10 2008 005 181 A1 describes a closing aid for pulling a flap or a door of a vehicle to the vehicle body.
  • the drive known from this also serves to open the door or flap.
  • a combined closing and an electric opening of a tailgate lock goes out of the pamphlets DE 100 33 092 A1 , DE 10 2004 011 798 B3 such as DE 10 2004 013 671 A1 out.
  • a handle of a door or flap may be part of the actuator. This handle is usually connected via a linkage or a Bowden cable with an actuating lever of the castle. If the handle is actuated, the actuating lever of the lock is pivoted by means of the linkage or Bowden cable so that the lock opens.
  • a motor vehicle can have a generally pivotable outer handle, which can be reached from the outside, and / or a generally pivotable inner handle, which can be reached from the inside.
  • a gap generally remains between the door or flap and the adjacent body.
  • Such a gap should be as low as possible, especially in hoods, which are seen in the usual direction forward to avoid adverse air turbulence in the front area and concomitant air resistance during a ride.
  • a possible gap-free, closed surface is also desirable for optical reasons.
  • EP 1 489 252 B1 is advantageously used with closing and opening assistance devices that generally ensure that after reaching a certain prelocking the distance between the body and the hood or door to be closed is reduced (closed position). This is generally done by motor or by means of a motor drive, although in principle a mechanical closing or closing is possible and is included.
  • opening devices with the aid of which the hood or motor vehicle hood or door or motor vehicle door in question is opened or displayed in relation to the motor vehicle body. In principle, such closing / opening devices can also be combined.
  • the German reservation DE 10 2013 109 051 deals with minimizing such gaps in doors or flaps.
  • the lock known therefrom is movable and in particular pivotally mounted. Following a locking of the locking mechanism, the lock is generally moved or pivoted by a drive in such a way that a gap between the door or flap and body is minimized.
  • the drive provided for this purpose comprises an electric motor and a pivotable lever, which is called a rocker. By pivoting the lever or the rocker (hereinafter also called “rocker arm”) by the electric motor, the lock is pivoted as a whole, that the gap is minimized.
  • the lock housing is held by a pawl which is rotatably mounted on the rocker.
  • a locking device according to the preamble of claim 1 is in the document DE 10 2009 018 188 A1 disclosed.
  • the main goal of the development is to position movable body components and in particular the vehicle hood directly above the attachments, such as a headlight, grille or body.
  • the vehicle hood should be positioned on or immediately above the other attachments, so that a 0-joint is achieved.
  • Such joints between attachments and / or the body and the hood on the one hand, as described, affect the aerodynamics of the motor vehicle and on the other hand crucially affect the visual and thus the overall qualitative impression of the vehicle.
  • a technical problem to be solved here is that when the motor vehicle hood is closed, primarily due to the weight, the hood performs an overstroke.
  • An overstroke here is the exceeding of the desired position of the closed hood, wherein the hood moves beyond the desired position, so that a 0-joint with conventional locks can not be realized. It is an object of the invention to provide a locking device and a method with which a gap of a door or flap can be minimized. To achieve the object, a closing device comprises the features of claim 1. Advantageous embodiments result from the dependent claims.
  • a locking device for a door or flap has a lock with a locking mechanism of the catch and pawl for locking the catch.
  • the lock comprises a closing aid so as to reduce an aforementioned gap by partially moving the locking mechanism.
  • a lock with closing aid comprises a rotary latch which can be locked in both a pre-locking position and in a main locking position by at least one pawl. If the catch is locked by a pawl, so is a blocking surface of the pawl directly against a locking surface of the catch. As a result, the catch is locked reliably so that this locking mechanism will not open even with larger external load.
  • the lock with a closing aid has a securing mechanism which prevents the locking mechanism from being manually moved from the pre-locking position to the main locking position.
  • a stop for the striker may be provided, which prevents the striker can be moved so far by closing a door or flap in the inlet mouth of a catch that the catch can be locked in the main latching position. If the locking mechanism is locked by a pawl in the pre-locking position, this position is registered by pressing a microswitch, for example. If a microswitch registers the pre-locking position, then the microswitch is actuated. The actuation of the microswitch then sets a electric drive in progress. The drive moves the stopper out of its stop position.
  • This embodiment is thus generally based on the consideration to provide a lock for minimizing the gap, which can be locked by at least one pawl in a pre-locking position and in a main latching position.
  • a Zuzieh Bü to lock starting from the pre-locking position, the locking mechanism in its main locking position.
  • a locking mechanism that causes the lock to be locked only by the electric drive in the main latching position.
  • a gap between a flap or a door and a body can be minimized, since this can be designed so that only a very small overtravel is possible. It is thus possible in particular to reduce the gap to 4 mm and less. It is even possible to achieve a gap of 3 mm and less.
  • An incidence of a latch bolt, which may be attached to a frame or door, flap or hood, into the catch causes an impact.
  • a stop for the rotary latch is attached to a plate in an advantageous embodiment.
  • this plate is preferably made of metal and is in particular on the body or on a door or flap of a motor vehicle attached. The plate may also be part of the bodywork of a motor vehicle.
  • the load caused by said impact is introduced by the rotary latch via the stop in the plate.
  • the locking bolt rotates the rotary latch in the direction of the closed position.
  • the rotary latch finally hits the stopper by its rotary motion and introduces the load connected to the impact into the stop.
  • the introduced into the stop load is then forwarded via the attachment of the stop on the plate in the plate. It is thus avoided damage to the drive by the impact and the associated mechanical stress. It is not necessary that the load is transmitted directly from the catch to the stop. It suffices an indirect transfer of the load into the stop inside.
  • the locking device is such that the catch is latched by the pawl before the load is introduced into the stop. This ensures particularly reliable that the locking mechanism can be locked as planned.
  • the catch is advantageously locked in the Vorrastpostion reasons mentioned above. The stop then prevents the catch in the main latching position can be locked.
  • the lock housing and thus a locking mechanism located in the housing are pivotally mounted about an axis to a base member.
  • the movement of the lock housing in the course of a closing or opening operation is effected by a pivoting movement of the lock housing about said axis.
  • the rotary latch is pivoted by a drive, ie not manually, into the main latching position and latched here.
  • the lock case or the lock plate of the lock housing is preferably rotatably mounted. With the lock case or the lock plate rotary latch and pawl are rotatably connected by means of axes.
  • the drive By means of the drive, the lock case or the lock plate is pivoted so that a gap in a door or flap can be finally reduced.
  • the presence of a lock cover is in this embodiment, although advantageous, but not mandatory.
  • the lock case or the lock plate is rotatably mounted on the plate to which the stopper is attached. This contributes to a small number of components and to a small space.
  • a rocker arm ie a pivotable lever, connected via a common axis with the rotatably mounted lock case.
  • the term axis also means the case of a wave.
  • the drive can move the free end of the rocker arm, thus also the rotatably mounted lock case for a reduction of a gap in a door or flap.
  • leverage forces can be used suitably to move with suitable large force, the locking mechanism for reducing a gap of a door or flap.
  • This embodiment is an independent invention regardless of the stop, with which the technical problem is solved to be able to minimize a door gap or flap gap by a simply constructed locking device.
  • the lock case extends from the common axis seen in the same direction as the rocker arm. As a result, the space is advantageously kept small.
  • the rocker arm extends from the common axis looking beyond the inlet region of the lock case or the lock plate addition. It are provided so favorable leverage ratios to use an electric motor with low power, which can then be advantageously built particularly small.
  • a manually operable Bowden cable can act on the locking device suitable.
  • a motor drive for the closing and / or opening device is provided.
  • the drive only then moves the locking mechanism overall in order to minimize a door gap or flap gap when the lock is in its main latching position.
  • This embodiment therefore comprises, in particular, a sensor or a microswitch, with which it can be determined when the locking mechanism is in the main latching position. If the sensor or microswitch registers that the ratchet is in the main latching position, then the sensor or microswitch will activate the drive to reduce the remaining gap in a door or flap and minimize it where possible.
  • the catch has been previously moved by a closing aid from the pre-locking position to the main locking position so as to minimize a gap even by this movement alone. The ratchet then has to be moved only very slightly in order to avoid virtually any gap (zero joint). As a result, the required space can be minimized.
  • the rocker arm is preferably rotatably mounted on one or more plates.
  • the one or more plates consist of Stability reasons preferably made of metal.
  • the one or more plates preferably have tabs with which the plates can be attached to the body of a motor vehicle or to a door or hood of a motor vehicle.
  • the one or more plates then serve on the one hand the rotatable mounting of the rocker arm and on the other hand the attachment to the motor vehicle.
  • the stopper is preferably rotatably mounted on the plate. This embodiment makes it possible to move the stop when needed from its stop position and in particular by an electric drive.
  • the drive able to move the ratchet can also move the stop so as to minimize the number of drives required.
  • this drive is also part of the closing aid.
  • the drive can rotate a disk from which an eccentrically arranged bolt protrudes.
  • the bolt is thus arranged away from the center of rotation or axis of rotation of the disc.
  • the bolt extends into a slot of the rocker arm for moving the locking mechanism out. This means that a rotation of the disc causes a pivoting of the rocker arm and thereby also a movement of the locking mechanism.
  • the bolt is alternatively or additionally used to move the stop suitable.
  • it is possible in an advantageous manner to move the stop out of its stop position after said load has been introduced into it. Moving out of the stop position then allows the ratchet to move to reduce the gap.
  • the rotatable components of the locking device may be biased by springs to move components into desired positions by spring force.
  • a closing of the hood can be done in particular on a zero joint or a 0-gap dimension on the pawl.
  • the rotary latch preferably forms the axis of rotation for the lock.
  • the drive acts on the pawl and thus makes it possible to move the hood after closing the locking in a 0-gap.
  • This embodiment represents an independent invention independent of the stop, but can be combined with the aforementioned features.
  • the pawl then forms a rocker arm which can be driven by a drive so as to minimize a gap.
  • the invention preferably relates to a lock for a hood of a motor vehicle, in particular for a hood.
  • a gap or a gap of about five millimeters is provided. This gap is necessary because the hood when closing passes through an overstroke of about 5 mm. This overstroke requires that between the hood and the attachments, such as the grille or the headlight, a gap of at least 5 mm must be present.
  • a door or flap such as a hood, caught in a preliminary catch and moved by means of a preferably electric motor drive from the pre-rest in the main rast ,
  • a preferably electric motor drive from the pre-rest in the main rast .
  • the rotary latch has a preliminary catch and a main catch, into which the hood lock comes in when closing the front flap. After reaching the main load then the catch would be pulled in an overstroke of, for example, six millimeters by means of a drive.
  • a third detent position is provided, for example, on the rotary latch.
  • the entire lock unit is moved in a 0-joint position.
  • the lock will be accommodated mounted in an eccentric drive, so that the castle would close in an excessive position.
  • the entire lock is then in particular driven by an electric motor pivoted by means of the drive, so that the door or flap in turn can be moved in a 0-joint position.
  • the invention is in one embodiment, the technical problem of further developing such a locking device so that with simple means the smallest possible gap between the body and door or hood can be provided.
  • a generic locking device in the invention is characterized in that the closing and / or opening device on the outside on Lock housing attacks to its adjustment relative to a stationary base element in the course of a closing / opening process.
  • the stationary base element is a component of this motor vehicle body.
  • the motor vehicle door lock or hood lock according to the invention is located in the region of an upper front carrier on the front of the motor vehicle body, which is typically arranged or extends horizontally.
  • the design is advantageously made such that the lock housing is pivotally connected to the base element in question about an axis or axis of rotation. That is, the adjustment of the lock housing in the course of the closing / opening operation corresponds to a pivoting movement of the lock housing about the axis in question or axis of rotation.
  • the axis or axis of rotation is generally defined such that in the example, the upper front support of the vehicle body is equipped with a corresponding pin or pin on which the lock housing is rotatably mounted.
  • the lock case is generally rotatably mounted on the bolt in question.
  • the lock cover is connected to the lock case and is taken along during a pivoting movement of the lock case as it were.
  • the described closing / opening process can basically be carried out mechanically.
  • this may include a Work Bowden cable on the closing and / or opening device that can be operated manually.
  • a motor drive for the closing and / or opening device is provided. It has been proven that the motor drive works eccentrically on the closing / opening device. Moreover, it is advantageous if the motor drive only then acts on the closing and or opening device when the door lock is in its main latching position.
  • the closing and / or opening device essentially consists of a rocker and a pawl acting on the lock housing.
  • the rocker With the help of the rocker relatively large torques can be exerted on the lock housing, even when working with a small-build motor drive, which applies a rather small force.
  • the rocker is usually rotatably connected to the base member. It has proven useful if the rocker and the lock housing are connected coaxially rotatable to the base element. In this case, therefore, the bolt acts on the upper front support of the vehicle body advantageous as a common axis of rotation for one hand, the lock housing and on the other hand, the rocker. In addition, this provides a particularly compact and less bulky construction available.
