Description

INDUSTRIAL APPLICABILITY The present invention relates to an automobile lock, particularly an electrically actuable automobile lock, wherein the automobile lock has a rotation catch and a lock mechanism having at least one claw portion and a release lever, and the rotation catch is at least. It can be latched by a claw in one latch position, and the latched locking mechanism can be unlocked by a release lever.

Automotive locks are used in automobiles where components that must be placed swivelly, displaceable, or otherwise movable on the vehicle must be secured. In particular, high standards have been set for the side doors and tail doors in consideration of operability. Therefore, the developers of automotive locks are constantly striving to improve the operational comfort of automotive locks.

Automotive locks, especially locking mechanisms located within the automotive lock, typically interact with a lock holder fixed to the body of the vehicle during closure. The locking mechanism consisting of the rotary catch and the claw portion is moved to the latch position by the lock holder. This latch position allows for a pre-latch position and a main latch position, allowing the movable component to be reliably positioned and held during use of the vehicle. The latch position is achieved, for example, by engaging the claws on the latch surface of the rotary catch so that the locking mechanism can be moved to the main latch position. The interaction between the locking mechanism, i.e., the rotary catch and the claw, causes noise during opening and closing, which greatly affects the comfort of the automotive lock.

In automotive locks, which became known from DE10 2016 215 336A1, for example, a ball-shaped locking element is used between the rotary catch and the claws to achieve good haptic and acoustic effects of the automotive lock. It is located in the joint area. To ensure that the ball is guided to the engagement area between the rotary catch and the claw, this document discloses a guide cage, which is located on the claw or catch. ..

From DE10 2007 003 948A1, a lock unit with a locking mechanism is known, which has a first claw that engages with a rotary catch by a blocking lever. It is held in the state. The locking mechanism is equipped with a pre-latch and a main latch. A release lever is used to achieve pre-latch, but the release lever can engage the bolt on the rotary catch so that the pre-latch position is achievable. At the main latch position, the first claw engages the rotary catch so that the interaction between the rotary catch and the claw results in an opening moment, and the first claw becomes the opening moment of the first claw. A blocking lever that reacts is provided. To release the locking mechanism, the blocking lever can first be disengaged from the claw and then the disengagement lever can disengage the claw from the rotary catch.

An object of the present invention is to provide an improved automobile lock. The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an automobile lock capable of minimizing the opening noise of the locking mechanism and facilitating the opening of the locking mechanism. .. Further, an object of the present invention is to provide a locking mechanism particularly suitable for electrical unlocking. Finally, it is an object of the present invention to provide a structurally advantageous solution for quiet and easy opening.

This object is achieved by the characteristics of Independent Claim 1. An advantageous embodiment of the invention is specified in the dependent claim. It should be noted that the exemplary embodiments described below are not limiting, but rather allow any possible variation of the features described in the description and dependent claims.

The object of the present invention according to claim 1 is an automobile lock, particularly an electrically actuable automobile lock, which has a lock mechanism having a rotation catch and at least one claw and a release lever, and rotates. The catch can be latched to at least one latch position by the claw, the latched locking mechanism can be unlocked by the unlock lever, and the rotary catch unlocks the locking mechanism at least indirectly by the unlocking lever. Achieved by the provision of automotive locks, which are particularly movable to raised positions. According to the configuration of the automobile lock device according to the present invention, it is possible to provide an automobile lock that is quiet and can be easily opened. In particular, the interaction between the release lever and the rotary catch during the opening process allows the claw to be moved from the engagement area by the rotary catch, thus preventing separation noise, that is, the noise of the claw slipping off the rotary catch. , Or at least to a minimum. If the release lever engages the rotary catch during the opening process and the claw moves at least the rotary catch from the rotary catch to the releaseable closing position, the release lever should be displaced simultaneously with the claw or at least temporarily. The claws can be easily and quietly moved from the area of engagement with the rotary catch.

The locking mechanism is held in the latch position by the claws. Unlatch or disengagement of the claws and rotary catch is also called unlocking. There is a locking mechanism with one or two latching positions to distinguish between a pre-latching position where the locking mechanism is not yet fully closed and a main latching position where the locking mechanism is in the locked closed position. For example, starting from the closed position, the release lever interacts with the rotary catch so that the rotary catch moves to a raised position beyond the main detent position, thus unloading the claws. The unloaded claws can be easily moved from the area of engagement with the rotary catch. The load from the rotary catch, eg, the door seal pressure, is applied by the release lever to unlock the locking mechanism. In an advantageous embodiment, the release lever can raise the rotary catch, i.e., release the claw portion from the load of the rotary catch.

Reference to automotive locks within the meaning of the present invention includes, for example, automotive locks used in side doors, sliding doors, flaps, hoods and / or covers, where swivel or displaceable. Components are placed in the car. It is also conceivable to place an automobile lock on the backrest of the seat.

Automotive locks have a locking mechanism with a rotary catch and at least one claw. Preferably, in particular, at least one claw is placed in a plane with the rotary catch and can work with the latch element and lock holder to lock the rotary catch in one position. When the locking mechanism is open, the inlet mouse of the rotary catch is pointing towards the lock holder and the rotary catch swivels as a result of the relative movement between the lock holder and the rotary catch. The claws are typically pretensioned in the direction of the rotary catch, and when the latch position is reached, the claws, especially the latch element, engage the rotary catch. Here, the pre-latch position and the main latch position of the lock mechanism can be assumed.

In addition, the lock system or automotive lock can have a lock housing in which the lock mechanism, lock unit, actuation unit, electric drive and / or gear component can be arranged. This list is, of course, not exhaustive, but merely a list of automotive lock components that can be used depending on the intended use and scope of functionality. The lock housing is preferably designed as a plastic injection molded part and can be configured from at least one lock housing cover and lock housing shell. The lock housing primarily serves to protect functional components from, for example, infiltrating moisture and / or dirt. The lock housing components are hermetically sealed and connected to each other.

The locking case can be designed as a stamped bent part and encloses the housing at least in specific areas and / or on both sides. The lock case can enclose the entrance mouse of the lock holder, which helps to further stabilize the lock. The automotive lock is preferably directly connected to and screwed to the automotive body via a locking case or a lock plate as a flat locking case.

The lock plate is preferably provided with a means for mounting, for example, a mounting opening, preferably as a screw.

The release lever can be manually and / or electrically actuated. In particular, in the case of a locking system in which the release lever can be electrically actuated, an electrical locking system is referred to. Here, in various embodiments of the vehicle, for example, mechanical redundancy due to an external actuating lever can be completely eliminated. However, hybrid embodiments are also possible in which the locking mechanism can be electrically and mechanically unlocked. The release lever is arranged in the automobile so that the claw portion is disengaged from the claw portion by the release lever. Further, according to the present invention, the release lever can operate the rotary catch and move it directly to the ascending position by moving the claw portion from the engagement area with the rotary catch.

This ascending position unloads the claws, which facilitates unlocking, resulting in quieter unlocking of the locking mechanism. Of course, there is also the option of using the locking claw with the blocking lever, in which case a two-claw locking mechanism is also used and the release lever can actuate both claws and the rotary catch. In the present invention, it is important that the release lever unloads the claw portion that is directly engaged with the rotary catch. In this way, noise due to relative motion between the rotary catch and the claw can be reduced and / or eliminated. As a result, the lock mechanism can be quietly released.

In a modification of one embodiment of the invention, the release lever can be engaged with the outer shape of the rotary catch, in particular a cylindrical pin or bolt. As a result of direct engagement with the outer shape of the rotary catch, the interaction between the release lever, especially the release lever and the rotary catch, can be interpreted in terms of low noise generation. In particular, the interaction between the release lever and the rotary catch makes it possible to obtain an engagement ratio suitable for the release lever to roll the rotary catch. It is conceivable that an outer shape in the form of a cylindrical pin or bolt is placed on the rotary catch so that the release lever rests with respect to the radius.

For example, if the end of the release lever that engages the bolt is also provided with a radius, rolling may occur. The rolling function allows the release lever and rotation catch to be gently disengaged. Of course, in addition to the arrangement of cylindrical pins and bolts, a shape that can bring engagement to the release lever may be incorporated directly into the rotary catch. The rotary catch is preferably formed from a steel part with a plastic casing. Similarly, preferably, the metal region of the release lever interacts with the metal region of the rotary catch so that on the one hand a permanently stable force can be transmitted and on the other hand a good engagement state for a long period of time. Can be secured.

Another embodiment of the present invention is obtained when the release lever is mounted on a swivel shaft common to the claw portion. By arranging the release lever at the bearing part of the claw portion, the lock for automobiles can be designed compactly. Further, by mounting the release lever swingably, it is possible to achieve a circular path through the end of the release lever engaged with the rotary catch. As a result, the rotation of the release lever on the rotation catch can be positively supported. On the other hand, the bearing portion of the release lever is preferably fixed for mounting the release lever because the claw portion and the rotation catch are mounted in the lock case and / or by the reinforcing plate in the lock for automobiles. Form the means.

Since this stable mounting can be used for the release lever, the release lever can also be provided with a sufficiently stable mounting. In particular, an appropriate lever ratio of the release lever can facilitate lifting from the rotary catch or from the claw portion. With a suitable lever ratio, the release lever can also reliably move the rotary catch to the raised position by an electric drive.

Further, in addition to mounting the joint between the release lever and the claw portion on one axis, it is also conceivable to provide a separate mounting. Pivot shafts, or in the case of separate mounting, the two pivot shafts are preferably mounted in a metal lock case. It can also be attached to a reinforcing plate, for example. Similarly suitable metal reinforcing plates can be accommodated in the lock case to provide bearing cages for the swivel shaft or the two swivel shafts.

Further, it is advantageous that the outer shape portion of the rotation catch itself is arranged so as to be able to rotate or rotate on the rotation catch. Rolling between rotary catches can be achieved by arranging a swivel or rotatable outer shape.

In a modification of a more advantageous embodiment of the invention, it is obtained when the means for achieving rotational motion is located in the engagement zone between the rotary catch and the release lever. The means for achieving rolling motion, i.e., rolling means, on the one hand offers the possibility of achieving further translation between the release lever and the contour on the rotary catch, and on the other hand. , Provides the possibility of designing and / or optimizing the engagement conditions between the release lever and the rotary catch. In particular, the rolling motion of the rolling means can prevent the release lever from slipping off the outer shape of the rotary catch. This makes it possible to achieve a quiet unlock of the locking mechanism.

It should be pointed out that in this exemplary embodiment, if unlocking the locking mechanism is preferred, the movement of the rotary catch according to the invention by the unlocking lever can also be advantageously used to lock the locking mechanism. be. To move the release lever to the closed position of the locking mechanism, move the release lever to the area of engagement with the rotary catch and bring the rotary catch to the raised position. In this raised position, the claw can reliably fall into the area of engagement with the rotary catch. As a result, the lock mechanism can be reliably locked by the interaction between the release lever and the rotary catch.

The rolling means is advantageously a cylindrical body, particularly a rolling element, that results in further modifications of the present invention. The cylindrical body, in particular the rolling element, provides the advantage of a favorable engagement state between the rotary catch outer shape and the release lever. Further, preferably, the rotation catch outer shape portion has a radius so that the cylindrical body can perform a rolling motion with respect to the rotation catch outer shape portion. The outer shape of the rotary catch is preferably a bolt or a cylindrical pin. As an example, the diameter of the rolling means is, for example, 5 to 15 mm, preferably 8 to 12 mm, and more preferably 10 mm. If the cylinder or rolling element is rollable on a rotary catch, the end of the release lever that engages the rolling element can also form a suitable surface for rolling.

Here, it is also conceivable to form a radius or a flat surface. Next, the rolling element can be rolled between the release lever and the outer shape of the rotary catch. Within the automotive lock, the rolling elements may be guided by a release lever and / or a rotary catch and / or a lock housing and / or a reinforcing plate. The guide secures the rolling of the rolling element to the extent that the claw can be separated from the rotating catch, enables the rolling element to roll reliably, and releases the release lever from the engagement area with the rolling element or the rotating catch. Designed to be easily and quietly disengaged.

In a modification of another embodiment of the present invention, the rolling means is a bearing, particularly a deep groove ball bearing. By using standard components such as commercially available deep groove ball bearings, structurally preferred solutions for activating rotary catches can be provided. In addition, series or off-the-shelf parts offer the advantage of guaranteeing reliable operation over time.

Another embodiment of the invention is obtained when the radial end of the release lever is engaged with the rolling means. The target design of the engagement surface of the release lever can favorably affect the transmission of force between the release lever and the rolling means. In particular, it is possible to introduce a large force and moment into the rolling means by the release lever. For small translations in the rolling means, a large lever arm on the release lever can generate a suitable force ratio, so that a large force can also be used to move the rotary catch to the ascending position. At the main latch position, for example, there is a rotation catch at a position where the entire sealing pressure of the door is absorbed by the locking mechanism. Therefore, the movement of the rotary catch from the main latch position to the raised position requires a large force or moment, which is due to the favorable design of the lever ratio and the point of application of the force, eg the radius of the release lever. It can be achieved at the directional end.

When the radial end of the release lever moves on a circular path, a modification of another embodiment of the invention is obtained. The circular path of the release lever provides the possibility of rolling on the release lever. The contact surface or contact surface on the release lever is designed to provide a rolling path for the rolling means, so that the rotary catch moves reliably to the raised position and at the same time with the rotary catch. It is possible to secure the disengagement of the claw portion from the engagement area. In an advantageous embodiment, the rolling motion between the rolling element or rolling means and the rotating catch can be achieved by the rolling element. Here, the rolling means or the rolling element can be understood as a synonym, and the rolling element functions as a connecting means between the release lever and the rotation catch outer shape portion. In addition to the embodiment of the cylindrical body as the contact outer shape on the rotary catch, it is also conceivable that the rolling element faces an arcuate, convex or elliptical surface. The rotary catch can be lifted from the claw portion by the interaction between the circular segment-shaped motion of the end of the release lever, the rolling motion of the rolling element, and the engaging outer shape on the rotary catch. This allows the locking mechanism to be easily and quietly unlocked or locked.

In another modification of the embodiment, in the opening operation of the locking mechanism, the rolling element, particularly the release lever, can be provided with an opening force in at least a part of the area. The interaction between the release lever and / or the rolling element and the rotating catch outline is that when the locking mechanism is fully locked, i.e. in the main latch position, the release lever and / or the rolling element is the release lever and / or. Alternatively, the rolling element can be designed to move to a position where it can be held in the closed position. When the locking mechanism is released, the release lever is then moved and moves against the rolling elements or the outer shape of the rotary catch. In this case, a force or moment is applied to the rotary catch, lifting the rotary catch from the claw. The rotary catch can provide an open moment or force that moves the release lever to the open position after the claw has been moved to the outer area of engagement with the rotary catch. Therefore, the rotary catch assists in unlocking the locking mechanism or vehicle lock. Thereby, the rotation catch or the force acting on the rotation catch can assist the unlocking operation of the lock.

Another object of the present invention is to provide a method for easily and quietly unlocking an automobile.

This purpose is achieved by a method of unlocking the locking mechanism of an automotive lock having a rotary catch and at least one claw, in which the rotary catch is locked to the main latch position by the claw and the release lever. The release lever first moves the rotary catch before the opening action is brought to the claw. According to the method according to the present invention, it is possible to unload the claw portion before the opening operation, thereby preventing the noise generated during the relative movement between the claw portion and the rotary catch, and particularly the opening operation. It is possible to prevent the impact of time, that is, the obstruction of the engagement between the claw portion and the rotary catch.

In an advantageous embodiment, a method can also be provided that allows for a secure closure of the locking mechanism. For this purpose, the rotary catch is moved to the raised position by the release lever and / or rolling element before the claws are engaged, whereby the claws can be reliably dropped. The rotary catch is held in a forced position that ensures that the claws are securely engaged. In a more advantageous method step, the rotary catch is moved to a particularly raised position by the release lever and via a rolling element located in the engagement area between the rotary catch and the release lever. By using a rolling element, a transmission step can be provided, and there is an advantage that a rolling element that reliably rolls in the process of opening and closing the lock mechanism can be obtained. In any case, according to the configuration of the automobile lock according to the present invention, the lock mechanism can be reliably closed and easily and quietly opened and unlocked.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings, based on suitable exemplary embodiments and force-time curves. However, exemplary embodiments do not limit the invention, but the principle that they merely represent embodiments apply. The features shown can be implemented individually or in combination with the further features of the specification and claims.

Detailed description of the invention

FIG. 1 shows a top view of a lock mechanism for an automobile, particularly a lock mechanism including a rotary catch 3 and a claw portion 4. The lock mechanism 2 is arranged at the main latch position, and the lock holder 5 is held by the automobile lock 1 at a closed position, for example, in the side door. The lock holder 5 brings a force F that generates a moment M in the clockwise direction around the axis 6 of the rotary catch 3 to the rotary catch. The shaft 6 of the rotary catch is rotatably received by the lock plate 7. Another shaft 8 is also held by the lock plate 7, which simultaneously functions as the bearing shaft 8 of the release lever 9. In the engagement area 10 between the claw portion 4 and the rotary catch 3, the bare metal regions of the claw portion 4 and the rotary catch 3 are preferably in contact with each other. At the main latch position shown in FIG. 1, the claw portion 4 is placed on the rotary catch 3 in the engaging area, and in a part of the area, it is mounted on the plastic casing 11 of the rotary catch 3. Such a plastic casing 11 is advantageously used to quietly support the rotary catch in the shaft and to form the damping means 12 on the rotary catch 3.

In this exemplary embodiment, the bolt 13 is formed on the rotary catch 3 and projects from the plane of the rotary catch 3, so that the bolt 13 is on a plane parallel to the rotary catch 3 and a plane of the release lever 9. Be placed. The rolling element 14 is arranged between the release lever 9 and the bolt 13 and guided to the main latch position, and is separated from the bolt 13 in the present embodiment. The guide of the rolling element 14 can be formed, for example, by a release lever 9, for example, in the form of a guide cage, by a reinforcing plate between the shafts 6 and 8 of the lock housing and / or the rotary catch 3 and the claw portion 4. .. FIG. 1 shows the basic interaction of a release lever 9, a rolling element 14 and a bolt 13 for explaining the functional principle of the present invention. The guide cage of the rolling element 14 is not shown for easy viewing of the drawings.

Considering FIG. 1 here, the metal regions of the rotary catch 3 and the claw portion 4 face each other in the engagement zone 10 between the rotary catch 3 and the claw portion 4. As is known from the prior art, when the release lever 9 moves the claw portion 4 from the engagement zone of the rotary catch 3 by the drive outer shape portion 15, friction between the lock mechanism parts 3 and 4 of the engagement zone 10 Is generated, noise is generated, and easy opening is hindered. With the configuration of the automotive lock according to the present invention, the release lever can reduce or completely eliminate friction. Therefore, a quiet and easy release of the locking mechanism is guaranteed.

In FIG. 2, the lock mechanism according to the invention according to FIG. 1 is shown at a position where the claw portion 4 is released by the release lever 9, the rolling element 14, and the bolt 13. As can be seen from the comparison between FIGS. 1 and 2, the rectangle 16 is swiveled, and the rectangle 16 is illustrated merely to indicate the swivel or rotational motion of the rolling elements 14. In FIG. 2, the release lever 9 moves clockwise in the direction of the arrow P1, so that the rotary catch moves to a position raised from the main detent position HR. This means that the rotary catch has moved further in the closing direction. At this time, since the release lever 5 is engaged with the drive outer shape portion 15, the claw portion 4 can be easily released from the rotation catch 3 without making a noise. Therefore, the lock mechanism parts 3 and 4 are released without applying torque or by applying a slight torque due to the torque M of the rotary catch, and the claw portion 4 from the rotary catch 3 is released without noise. It is possible.

In FIG. 3, the position of the rotary catch is shown at the raised position again. As is clear from the rectangle 16 in the rolling element 14, the rolling element 14 is rolling on the bolt 13, and the rolling of the rolling element 14 is the movement of the end portion 17 of the release lever 9 on the circular path R. Or it is caused by the initialization of the rotational movement. The claw portion 4 is moved from the engagement area with the rotary catch 3 via the drive outer shape portion 15 by the release lever 9, and the lock mechanism 2 can be opened with almost or no noise. The sliding of the rolling element 14 and the opening of the automobile lock 1 are also performed by rolling the rolling element 14 on the bolt 13 of the rotary catch 3. As a result, the lock mechanism 2 can be easily and quietly released.

In FIG. 4, various force curves on the release lever during the unlocking process of the locking mechanism are shown over time. The curve 18 indicates the force that must be exerted on the locking mechanism by the release lever 9 in order to release the conventional locking mechanism having a coefficient of friction between the claw portion 4 and the rotary catch 3 of about 0.3. At time t1, the release lever 9 moves, and until time t2, the frictional force between the rotary catch 3 and the claw portion 4 must be overcome. Next, since only the claw portion 4 must be moved by the release lever 9, the force drops sharply.

The force profile by line 19 shows the opening process of a conventional locking mechanism with a coefficient of friction of 0.5. Such a high coefficient of friction occurs, for example, in a very old and dirty lock, for example, dust can enter between the rotary catch 3 and the claw portion 4, so that the engagement area 10 is very large. It is dirty and must overcome high friction to open the locking mechanism.

On the other hand, the force profile 20 shows a completely different force profile. At time t0, the rotary catch 3 is moved to the raised position, and a peak load is generated on the release lever 9. A continuous decrease in force corresponding to the rolling motion of the rolling element 14 on the bolt 13 continues. At time t3, the rotation catch 3 brings a force F to the release lever 9 to assist the opening work of the lock mechanism 2. As is clear from FIG. 4, the opening or unlocking process is significantly different from the usual force profiles 18, 19 of known locking mechanisms. According to the structure of the automobile lock 1 according to the present invention, the lock mechanism can be easily and quietly released, and the lock mechanism can assist the opening operation.
