Description

Motor vehicle door lock

description

The invention relates to a locking device for a door or flap of a motor vehicle with a locking mechanism comprising a rotary latch and a pawl for holding the rotary latch in a closed position. A closure device for a door or flap of a motor vehicle serves to secure the door or flap against unintended opening in the closed state of the door or flap, e.g. during a drive. The available space for such a closure device, which is usually integrated into the door or flap, is usually extremely limited. Especially in motor vehicles with electric opening function, which require integrating corresponding, additional components in the door or flap, there is a need for particularly compact closing devices.

The document DE 103 20 459 A1 discloses a closing device for a door or flap, namely a motor vehicle door lock, with a rotary latch and a pawl, wherein a damping stop is mounted on the rotary latch.

DE 100 21 768 A1 discloses a locking device for a rear seat back, so no closing device for a door or flap with the above-described specific space limitations.

The abovementioned features known from the prior art can be combined individually or in any desired combination with one of the objects according to the invention described below.

It is an object of the invention to provide a further developed closure device for a door or flap of a motor vehicle. To solve the problem, a closing device for a door or flap of a motor vehicle according to claim 1 is used. Advantageous embodiments will be apparent from the dependent claims. The object is achieved by a locking device for a door or flap of a motor vehicle with a locking mechanism comprising a rotary latch and a pawl for holding the rotary latch in a closed position, wherein the pawl is rotatably mounted on the rotary latch. The closing device for a door or flap of a motor vehicle generally serves to secure the door or flap against unscheduled opening in the closed state of the door or flap, for example, during a drive.

A rotary latch is basically rotatably mounted and can normally be pivoted between an open position and a closed position. In particular, the rotary latch in the open position can receive a locking bolt which, when the door or flap is closed, preferably reaches an inlet mouth of the rotary latch from an open state into the closed state and is thus received by the rotary latch. In particular, the catch can pivot with a recorded locking pin from the open position to the closed position.

A pawl is used to hold the catch in the closed position, in particular so that the locking pin is securely held by the catch in the closed position. Generally, by holding the rotary latch in the closed position by means of the pawl, it can be effected that the rotary latch can not be pivoted unscheduled back into the open position, for example by a locking bolt pulling in the opening direction. An unplanned opening of the door or flap can thus be avoided by the pawl. Basically, the holding of the rotary latch in the closed position can be realized by a latching, namely in particular by a locking of the pawl, preferably with a stop. That the pawl is rotatably mounted on the catch, means that the catch provides the pawl rotation axis and / or a pivot bearing for the pawl, such as a pin. Since the pawl is rotatably mounted on the rotary latch, the pawl rotation axis and thus correspondingly the pawl of a pivoting movement of the rotary latch follows. In principle, a relative movement between the pawl and the rotary latch is possible only in the form of a rotation of the pawl relative to the rotary latch.

By a closing device for a door or flap of a motor vehicle, wherein the pawl is rotatably mounted on the rotary latch, the closing device for a door or flap of a motor vehicle can be provided particularly compact. Space can be saved. This in turn can make room for e.g. an electric opening device. In one embodiment, the locking device is such that by moving a stop for the pawl, in particular from a blocking position of the stop and / or in a release position of the stop, the locking mechanism can be opened. By stop is meant an independent of the pawl movable component. In particular, such a stop can limit a rotation of the pawl, preferably in such a way that this limit contributes to holding the catch in the closed position by the pawl. For example, DE 100 21 768 A1 discloses no movable stop for a tensioning pawl.

Stop for the pawl means that the rotatably mounted on the catch locking pawl can come into operation against the stop, in particular at least in one position of the movable stop, preferably the Blockadestellung. In general, the stop is located at least in one position on the path of movement of the pawl, which is composed of the rotational path of the pawl and the pivot path of the catch, and in principle by superposition. By means of a stop, by moving the locking mechanism can be opened, a flexible and / or modular use of the locking device is made possible. The locking device can be configured with a structurally identical rotary latch pawl unit optionally for a manual or electrical or manual and electrical triggering of the rotary latch. Triggering the rotary latch means that the rotary latch is no longer kept in the closed position according to plan and consequently preferably pivoted in the direction of the open position or in the open position.

In one embodiment, the closing device comprises two stop surfaces for the pawl, wherein the first stop surface is arranged at an angle to the second stop surface, wherein the angle is in particular greater than 30 °, preferably greater than 60 °, particularly preferably greater than 90 °. Two stop surfaces for the pawl means that the pawl abuts in operation against both the first stop surface and against the second stop surface. In particular, the stop has the two stop surfaces, ie the first stop surface and the second stop surface. Preferably, the stopper is a component. The angle can be measured between the normals of the two abutment surfaces. If the stop is, for example, cuboid, with the upper side being the first stop surface and a side surface being the second stop surface, then the angle is 90 °. If the upper side is the first stop surface and the lower side is the second stop surface, then the angle is 180 °. By providing two stop faces for the pawl, a particularly compact closing device can be provided.

In one embodiment, the pawl abuts against the stop or the first abutment surface during pivoting of the rotary latch from an opening position for receiving a locking bolt in the closed position. By this bumping can be achieved that the stop or the first stop surface rotates the pawl about the pawl rotation axis. Continued pivotal movement of the catch until it reaches the closed position is made possible. In one embodiment, the pawl for holding the rotary latch in the closed position is in particular directly against the stop or on the second stop surface or presses against it. Concern means also at least selectively in contact. By this concern or support can be achieved that a torque acting on the rotary latch for rotating the rotary latch is received in the open position of the voltage applied to the stop or the second stop surface pawl. Holding the catch and avoiding unscheduled opening of the locking mechanism can thus be made possible.

In one embodiment, the locking device includes a locking member for limiting rotation of the locking pawl relative to the rotary latch. In particular, the blocking element is immovably connected to the rotary latch or is a projection of the rotary latch. A particularly simple, reliable and compact mechanism for holding the rotary latch in the closed position can thus be realized.

In one embodiment, the pawl for holding the rotary latch in the closed position, in particular directly to the blocking element or presses against it. Concern also means here at least selectively in contact. In particular, between the pawl and the locking element for holding the rotary latch in the closed position, a flat abutment is provided, preferably flat over most of the surface of that side of the locking element, which faces the pawl in the closed position of the rotary latch. By a concern or support can be achieved that a torque acting on the rotary latch for rotating the rotary latch is received in the open position of the voltage applied to the locking element pawl. Holding the catch and avoiding unscheduled opening of the locking mechanism can thus be made possible.

In one embodiment, the pawl in the form of an elongated flat profile and / or overlapped surface with the rotary latch. In particular, the overlapping portion of the pawl is at least 40%, preferably more than 50%. One such surface overlap with the rotary latch allows a particularly compact and also robust construction. An elongated flat profile is typically a component whose length is at least twice the width and the width at least twice the thickness. Typically, the length and width that is perpendicular to the length are measured orthogonal to the pawl rotation axis and the thickness is parallel to the pawl rotation axis. Preferably, the ends of the elongated flat profile are square for the purposes of material saving or rounded, arcuate or semicircular in order to reduce wear of the material during operation.

In one embodiment, the pawl projects radially beyond the catch when the pawl engages the pawl. Specifically, in this case, the pawl abuts on a side of the locking member against which the pawl abuts when the pawl has been rotated in a rotational direction which is rectified to the pivoting direction of the catch from an open position to the closed position. Radial overhang refers to the pawl rotation axis or rotary latch pivot axis, which in one embodiment are parallel to one another. By a radial projection of the pawl, when the pawl is applied to the locking element, a snap closure can be realized in a very small space.

In one embodiment, the locking device comprises a pawl spring for biasing the pawl in a rotational direction which is rectified to the pivoting direction of the rotary latch from an open position to the closed position. By a prestressed in this manner pawl spring can be realized in a particularly simple and compact way a snap mechanism.

In one embodiment, in order to obtain a particularly reliable snap mechanism, the rotary latch is biased by a rotary latch spring, in particular torsion spring, about its rotary latch pivot axis in the pivoting direction of the rotary latch from its closed position to its open position. In one embodiment, the locking device is such that by a snap mechanism, the pawl allows pivoting of the catch from an open position to the closed position, but blocks an unintended pivoting of the catch from the closed position to the open position. Unplanned means that a user has not initiated any action to open or close the door or flap, but nevertheless appropriate forces are exerted on the locking mechanism, eg as a result of an accident. By design, however, means that a user has initiated a measure to open or close the door or flap, for example, by operating an inside door handle or outside door handle or by pressing a button for the electrical or mechanical opening of a door, tailgate or hood. A snap mechanism allows a particularly compact but functionally effective construction of the closure device for a door or flap. In one embodiment, the snap mechanism causes when pivoting the catch from an open position to the closed position, the pawl, which is pressed in particular by the pawl spring against the locking element, rotates from its initial position by the stop or the first stop surface against the pivoting relative to the rotary latch is, in particular against the force of the pawl spring. As a result, the pawl passes the stop and the catch continues its pivoting movement unhindered to the closed position. After this passing or grinding the pawl past the stop, the pawl is rotated back to the starting position, in the pivoting direction of the catch to the closing position, in particular by the force of the pawl spring. Preferably, the pawl is in the starting position on the locking element.

When pivoting the catch from the closed position to the open position, however, the pawl now abuts against the stop again, against an opposite or second stop surface of the stop than the above-described passage, ie the previous pivoting of the catch from the open position to the closed position. A rotation of the pawl in a rotational direction, which is rectified to the pivoting direction of the rotary latch from the open position to the closed position, however, is prevented or limited by the blocking element. In particular, as long as the stop is not moved into a release position or in other words as long as the stop is in its blocking position, the pawl consequently can not pass the stop, ie come in a direction of rotation past the stop, the pivoting direction of the catch from the closed position in the opening position is rectified.

In one embodiment, the shortest distance of the stop in its blocking position to the rotary latch pivot axis is smaller than the maximum distance of the pawl to Drehfallenschwenkachse or smaller than the distance of the pawl to Drehfallenschwenkachse when the pawl against the locking element. The pawl can so reliably abut the stop, i. when the stop is in its blockage position.

In a further embodiment, the shortest distance of the stop in its blocking position to the rotary latch pivot axis is greater than the maximum distance of the pawl to the rotary latch pivot axis or greater than the distance of the pawl to the rotary latch pivot axis when the pawl against the blocking element. The pawl can thus reliably pass through the stop when pivoting the catch from the closed position to the open position, i. when the stopper is in its release position.

In one embodiment, the closing device comprises a manual and / or a motorized driven device for moving the stopper, in particular from the blockage position preferably in the release position. In a manual device is sufficient to actuate an actuating lever, such as an internal operating lever or external actuating lever to move the stop in particular in the release position. In a motorized driven device provides a motor, for example, a hydraulic, electric or pneumatic motor, the force for moving the stopper, in particular to to move the stop to the release pitch. A high ease of use can be achieved. With manual and motorized device improved safety in case of failure or failure of the engine is given. In a further embodiment, the reset of the stop is carried out in particular by the release division into the blockage position by a spring. This saves power and energy.

In one embodiment, the stop may be linearly moved or linearly moved or rotated or only rotated. By a linearly movable stop can be manually operated particularly gentle. By a rotatable stop can be operated in a technically particularly simple and compact way motorized. In one embodiment, the stop is formed by a web on a turntable or by a movable part of a housing or lock case of the closing device. A particularly compact closing device can thus be provided. A bridge is a projection on the surface of the turntable. A movable part of a housing or lock case for the purpose of low production costs is a separate and therefore relatively movable part or for the purpose of increased robustness while saving space a separately manufactured part that is adapted to the shape of the housing or the lock case. In one embodiment, the locking device is a motor vehicle door lock. In particular, the locking device is a motor vehicle door lock with an electric opening device for the door.

For the reasons described above, the locking device according to the invention allows a space saving, which guarantees the additional advantage, especially for the specific requirements and the specific installation situation of a motor vehicle door lock that space for additional electrical Opening device is created, in particular without providing additional space.

Embodiments of the invention will be explained in more detail with reference to figures. Features of the embodiments may be combined individually or in a plurality with the claimed subject matter.

FIG. 1: Schematic representation of a closing device for a door or

Flap of a motor vehicle with electrical opening device Figure 2: Schematic representation of a closing device for a door or

Flap of a motor vehicle with a manual device In the figures 1 and 2, the pawl 2 is mounted on the rotary latch 1. A pawl spring 12, in particular a torsion spring preferably about the pawl rotation axis 14, presses the pawl 2 against a fixedly connected to the catch 1 blocking element 7, so that when concern the pawl 2 on the locking element 7, the pawl 2 radially over the circumference, so the outer edge, the catch 1 protrudes. In one embodiment, which is also realized in Figures 1 and 2, the locking element 7 is arranged on the side of the pawl 2, starting from the pawl rotation axis 14 which lies in the pivoting direction of the rotary latch 1 from an open position to the closed position. In particular, the pawl rotation axis 14 is covered in the direction perpendicular to the contact surface of the locking element 7 of the locking element 7, so that a short pawl can be arranged together with the locking element 7 near the outer edge of the rotary latch 1.

If the protruding pawl 2 encounters an obstacle, in particular with the projecting end during the pivoting movement of the rotary latch 1 into the closed position, ie the movable stop 3, the pawl 2 can deflect or elastically spring back against this pivoting movement of the rotary latch. The pawl 2 is thereby effectively pushed away from the obstacle or the stopper 3 until the catch 1 has continued so far the pivoting movement that the SPK passes the obstacle or the stopper 3, vorbeigeglitten or is passed by.

As soon as the pawl 2 has passed the obstacle or the stop 3, the pawl 2 snaps back into the radial orientation or into the position resting on the blocking element 7 by the pawl spring force 12.

The catch 1 is thus now held by the pawl 2 in the closed position against the obstacle or the stopper 3. Because in the pivoting direction of the catch to the open position, the pawl 2 blocks the catch 1, because a deflection or Nachfedern the pawl 2 by pushing and / or pressing against the locking element 7 in this pivoting direction of the catch 1 is not possible.

In the closure device shown in Figure 1 for a door or flap of a motor vehicle with an electric opening device of the stopper 3 is a projection or web 13 on a turntable 8, which can be rotated by an electric drive, not shown, about the turntable axis 20 and thus to move the stopper 3 in the release position and in particular in a blockage position. The rotary latch 1 is biased by a rotary latch spring 15, in particular a torsion spring to the rotary latch pivot axis 16 in the pivoting direction of the rotary latch 1 from its closed position to its open position, ie in the counterclockwise direction in Figures 1 and 2. In the closed state of the closing device, ie with the door or flap closed, the stop 3 of the turntable 8 is in a blocking position as shown in FIG. The rotary latch spring 15 presses on the locking element 7 applied to the locking element 7 pawl 2 against the second stop surface 5 of the stopper 3. The rotatable about the pawl rotation axis 14 pawl 2 is thus effectively clamped between the second stop surface 5 and the abutment surface of the locking element 7 and therefore can not deflect or rotate.

The force between the pawl 2 and the second stop surface 5 is thus absorbed by the blocking element 7 and in principle at least partially by the pawl rotation axis 14.

If the user now operates, for example, a control knob to open the door or flap, the hub 8 is rotated by the electric drive in a rotational direction (see dashed direction of rotation arrow in Figure 1 in a clockwise direction), which is rectified to the biasing direction of the pawl spring 12, ie an equal Has direction of rotation. Once the stopper 3 has reached the release position, the trajectory is free for the pawl 2 for pivoting with the catch 1 in the open position (see dashed direction arrow in Figure 1 in the counterclockwise direction), i. without relative movement between pawl 2 and catch 1. Since the rotary latch 1 is prevented due to the locking element 7 from pivoting into the open position for releasing the locking bolt 6, as long as the pawl 2 is prevented from pivoting, the structure described allows a particularly comfortable electrical opening of the door or flap at the touch of a button , After the opening operation, the hub 8 and thus the stopper 3 is moved back into the blocking position, in particular by a spring.

In one embodiment, the electrical opening device has an electric drive with a center zero position.

This is typically an electric drive, which is held in the deactivated state in a central position, for example by a spring. In particular, this center position corresponds to the blockage position of the stopper 3. A particularly simple electrical opening device can be realized. During a closing operation, ie when the door or flap is closed by the user, the pawl 2 pivots with the catch 1 in the direction of the closed position. By the pawl spring 12, the pawl 2 is pressed against the locking element 7 and is there until the pawl 2 abuts the stopper 3 in the blocking position, so the first stop surface 4.

Since the closing forces are greater than the biasing force of the pawl spring 12, the pawl 2 rotates when pushed against the stopper 3 against the force of the pawl spring 12 and is thus displaced or deflected by the stopper 3. After passing the pawl 2 on the stopper 3, the pawl 2 therefore rotates again by the biasing force of the pawl spring 12 back to the locking element 7 for abutment against the blocking element. 7

In particular, the web 13 is arcuate. Preferably, the web 13 is spirally, preferably starting at a rotational axis of the hub 8 and radially extending in the direction of the circumference of the hub 8. This allows for effective power transmission.

In particular, the width of the web 13 and / or the height of the web 13 increases steadily from the turntable axis 20 in the direction of the circumference of the turntable 8. This allows for effective power transmission.

In particular, the second abutment surface 5 is formed by the end of the web 13, preferably by the wider end. This end is preferably substantially parallel to a radial of the axis 20 of the axis of rotation.

In particular, the turntable 8 is arranged at an open end of the lock case 10. The preparation of an opening 1 1 as in the embodiment shown in Figure 2 can be saved. FIG. 2 shows a closing device for a door or hatch of a motor vehicle with a manual device for opening the closing device. The stopper 3 here is a movable part 9 of or on the lock case 10. In particular, a spring, not shown, for biasing the stopper 3 in the direction of its blockage position, which is shown in Figure 2. In the closed state of the locking device, the rotary latch 1 is analogously as described in the embodiment of Figure 1 held by the pawl 2 in the closed position. If the user now actuates an actuating lever, for example a door handle, the stop 3 is in particular moved or displaced linearly against the spring force from the blocking position into the release position. Analogously as described in the embodiment of Figure 1 so the pawl 2 can pass the stopper 3 and the catch 1 can be pivoted or pivoted into the open position.

When the operating lever is released by the user, the pawl 2 has already passed the stopper 3 and the stopper 3 is moved in particular by a spring back into the blocking position.

In a closing operation, so when the door or flap is closed by the user, the pawl 2 pivots analogously as described in the embodiment of Figure 1 with the catch 1 with in the direction of the closed position. By the pawl spring 12, the pawl 2 is pressed against the locking element 7 and is there until the pawl 2 abuts the stopper 3 in the blocking position, so the first stop surface 4.

Since the closing forces are greater than the biasing force of the pawl spring 12, the pawl 2 rotates when pushed against the stopper 3 against the force of the pawl spring 12 and is thus displaced or deflected by the stopper 3. After passing the pawl 2 on the stop 3, the pawl 2 therefore rotates again by the biasing force of the pawl spring 12 back to the locking element 7 for abutment against the blocking element. 7 In particular, in the housing or the lock case 10, an opening 1 1 is introduced, in which the pawl 2 is immersed when the pawl 2 holds the catch 1 in the closed position. This allows a compact design. Preferably, the movable part 9 of the lock case, which can form the stopper 3, forms an edge of the opening 11. This allows the implementation of a compact snap mechanism. An additional stop member 17 may be provided in one embodiment to form an edge of the opening 1 1, against which the pawl would hit when pivoting with the catch 1 beyond the closed position, starting from the open position. A protection of the lock case and thus increased safety in the event of a crash can be made possible.

In particular, as shown in Figures 1 and 2, the pawl rotation axis is arranged in the region of the tentacle. Preferably, the rotary latch axis is arranged closer to the tentacle than on the load arm. This allows a compact and effective snap mechanism. In one embodiment, the pawl assumes the function of a locking clutch. A closing device for a door or flap of a motor vehicle, in particular a motor vehicle door lock, usually comprises at least one lock plate or a particular metallic lock case with a lock plate arranged therein and usually made of metal, on which the rotary latch is mounted. The lock plate is usually provided with an inlet slot 18 for receiving the locking pin 6.

The catch 1 usually has a fork-shaped inlet mouth 19 formed by load arm and catch arm for receiving the striker 6 in the open position of the catch 1, into which the striker 6 of a vehicle door or flap, for example bonnet or boot lid, arrives when the door or door closes Flap is closed. The locking bolt then rotated with the help of the tentacle the catch 1 from an open position to a closed position. If the catch 1 has reached the closing position, it is held in this position by the pawl 2. The locking pin 6 can not leave the inlet mouth 19 of the rotary latch 1, as this is prevented by the load arm. This closed position is called the main detent position.

There are locking devices or motor vehicle locks with a second locking position, namely the so-called pre-locking position. The pre-detent position serves to intercept the corresponding door or flap if it does not reach the main detent position when closing.

In the Vorraststeilung the catch 1 is therefore not completely closed, however, an opening movement of the catch 1 is already prevented by the pawl 2 or a Vorrastklinke not shown. Finally, in the main catch position, the catch is completely closed. The pre-restraint thus represents a transition state between the opened state and the main rest and is provided for safety reasons. In one embodiment, the closed position is the main detent position. A particularly comfortable opening can also be realized electrically. In an alternative or additional embodiment, the closed position is the pre-ratchet division. A particularly secure and at the same time comfortable operable locking device can be made possible.

In one embodiment, the rotary latch pivots 1 with the voltage applied to the locking element 7 pawl 2 when closing from the opening position temporarily beyond the closed position to a position in which the pawl 2 is pre-ground on the stopper 3 and back to the contact surface of the locking element 7 is rotated. In this embodiment, the rotary latch 1 pivots in particular only then in the closed position. A reliable snap mechanism can thus be made possible even in confined spaces.
