Description

Automotive locks

The invention includes a damping element, a spring lip, a locking mechanism consisting of a rotary latch and at least one pole and a receptacle for a locking bolt, the receptacle comprising an input and an end, the locking bolt being secured in the lock by the locking mechanism. And, at least in the main latching position, an automotive lock that interacts with a rotary latch, a damper element and a spring lip.

In today's cars, the comfort of the car is paramount. While simplicity of operation is sought, the noise characteristics of the vehicle play a decisive role in the driver's perception of the quality of the vehicle. Especially in automobiles, the closing noise and the noise during driving are sought as much as possible or to be completely prevented. For example, there may be relative movement between the car lock and the lock holder interacting with the car lock, especially in an automobile. The relative movement between the lock holder and the car lock is caused by the vehicle body running on an uneven surface, for example during driving.

The lock holder, which can be designed as a bolt or striker, is fixed in the vehicle by a locking mechanism consisting of a rotary latch and a pole. For example, to ensure accurate locking of the car door, the locking mechanism holds the lock holder against the pressure of the door seal at the locking position of the door or at the main latching position. The lock holder is thus tensioned or pretensioned to contact the load arm of the rotary latch of the locking mechanism. Since the lock holder is mainly formed of a metallic material, a "creaking" noise can be heard when the lock holder and the rotary latch move relative to each other.

In order to reduce squeaking noises, EP 2 640 916 B1 discloses, in an automobile lock, supporting the lock holder or securing the lock holder under pretension. To this end, the automotive lock comprises a spring lip which interacts with the locking bolt in the locking position of the lock, in particular in the main latching position of the lock. If the lock holder is in the main latching position, the lock holder abuts against the metal clamp at the spring lip of the lock housing and is secured under pretension by the spring lip and the metal clamp. The pretension is intended to prevent relative movement between the lock holder and the car lock as much as possible.

DE 10 2008 058 419 A1 also discloses an automobile lock in which the spring lip interacts with the lock holder in the insert of the lock holder, in particular in the locked position. In this case, the spring lip is provided with a metal strip, which only interacts with the lock holder in the main latching position. The metal strip is arranged on the spring lip so that the first end and the second end can be formed on the spring lip. The metal strip is guided below the contact surface of the lock insertion lip in the first region and above the contact surface of the lock insertion lip in the second region. In this way, at the first site, the incoming lock holder is in contact only with the contact surface formed in the side of the groove and not in contact with the metal strip. Only at the second portion where the metal strip protrudes beyond the groove, the metal strip forms a contact surface with the lock holder.

Document DE 10 2008 031 206 A1 comprises a receptacle for a locking bolt, the receptacle comprises an input and an end having at least one damper element capable of absorbing contact forces generated from the locking bolt, the damper element being connected to the damper element. Disclosed is a device for an automotive lock having at least one opening provided with at least one insert that is rigid relative to it. After the damper element interacts with the lock holder, the damper element interacts with the spring lip to reduce noise. One variant discloses a spring lip which interacts with the rotary latch, damper element and spring lip in the main latching position so that the lock holder can be secured. When locked, the lock holder interacts with the damper element and the spring lip, while when the locking mechanism is opened, the rotary latch releases the lock holder directly without force from the damper element and / or spring lip limiting the opening process. . This is the starting point of the present invention.

The problem addressed by the present invention is to provide a locking system, in particular an automotive lock, in which the noise characteristics are optimized, ie better constructed. In particular, the problem addressed by the present invention is to reduce the opening noise when the lock holder is released by the locking mechanism. Furthermore, the problem addressed by the present invention is to provide a structurally simple and cost effective solution to reduce noise.

This problem is solved by the features of independent claim 1. Advantageous embodiments of the invention are indicated in the dependent claims. The example embodiments described below are not limiting; Indeed, modifications of the features described in the detailed description and the dependent claims are possible if necessary.

The problem addressed by the present invention is for a locking bolt, comprising: a receptacle comprising an input and an end; Damper elements; Spring lip; And a locking mechanism consisting of a rotary latch and at least one pole, wherein the locking bolt can be secured in the lock by the locking mechanism, interacting with the rotary latch, the damper element and the spring lip, at least in the main latching position, Is solved by providing a lock for an automobile comprising means for securing the lock holder. The design of the automotive lock according to the invention, together with the components of the automotive lock that locks the lock holder, makes it possible to further secure the lock holder in the automobile lock by a spring lip. Here, the securing means interact with the lock holder such that a force acting against the lock holder can be applied to the lock holder, at least when the locking mechanism is unlocked.

This additional force that can be applied to the lock holder by the spring lip makes the lock holder move more slowly away from the engagement area of the locking mechanism. This has a particularly advantageous effect on the noise produced when the locking mechanism is opened.

Various locking systems or locks can be used as automotive locks. Automotive locks can be used, for example, in compact assemblies in side doors, sliding doors or in the area of a hatch, cap or cover.

In a motor vehicle the locking mechanism comprises a rotary latch and at least one pole, which can be fixed in the locked position by the pole. A system with one or two poles and a two-stage locking mechanism consisting of one-stage and pre-latch and / or main latches can be used.

The release lever acts on the locking mechanism, which releases one or more poles from the rotary latch, for example by rotational movement. Preferably the release lever is rotatably mounted to the car lock, preferably to the housing and / or lock case of the car lock. The release lever unlocks the locking mechanism in the locked position, allowing the lock holder held by the locking mechanism to be released to allow the door to open, for example.

The present invention relates to a lock comprising a receptacle for a locking bolt, the receptacle also called an insertion opening. The receptacle includes an input for the locking bolt or the lock holder and an end to which the lock holder can be fixed in the main latching position. For example, when closing the rear hatch, the lock can move relative to the lock holder. If the lock moves toward the lock holder, the lock holder enters the input of the receptacle and contacts the catching arm of the rotary latch. As a result of the further relative movement towards the receptacle, the rotary latch is moved by the lock holder to the locking position so that the rotary latch can be fixed in the latching position by the pawl.

In order to improve the noise characteristics in the interaction between the lock holder and the lock, the lock according to the invention comprises a damper element and a spring lip which engages the damper element and the spring lip at least in the main latching position.

Upon unlocking, ie when the lock is opened, the lock holder is released from the locking mechanism. To closely secure the door or hatch to the vehicle, the door or hatch interacts with a seal that is compressed when the door or hatch is closed. This compressive force acts between the lock holder and the locking mechanism, causing a force that acts opposite the locking direction of the locking mechanism. When the locking mechanism is unlocked, the lock holder is released from the rotary latch.

In particular, the force acting on the locking mechanism causes the opening noise, which may also be called the opening clang. Opening noise is caused by the force that the pawl releases from the rotary latch, acting between the lock holder and the locking mechanism. The fastening means of the spring lip opposes the opening movement. By means of the fixing means of the spring lip, a force opposite to the opening movement is applied to the lock holder. This has a positive effect on the opening noise, and preferably substantially reduces the opening noise.

In a variant of the invention, the spring lip interacts with the damper element such that the damper element supports the locking of the lock holder and in particular provides an additional force for securing the lock holder. The spring lip at least partially covers the damper element. Here, the damper element extends at least partially below the spring lip so that at least the lock holder can be fixed in the main latching position by the interaction between the damper element and the spring lip. Here, the damper element acts as an additional support for the fastening means, so that an additional force for securing the lock holder can be provided in the main latching position. Indeed, the damper element extends below the spring lip and at least partially surrounds the spring lip so that the spring lip can be guided by the damper element. This stabilizes the position of the spring lip and at the same time increases the resistance of the spring lip to long term stress.

In an advantageous variant, the spring lip interacts form-fittingly with the lock holder. The shape locking engagement of the locking means in the lock holder makes it possible to achieve a reliable interaction between the lock holder and the locking means. In particular, the lock holder can have a shape which extends circularly or cylindrically in the area of interaction with the fastening means, and the spring lip can have a circular segment shape in the area of the fastening means. Thus, the fastening means can be in conformity to the lock holder in the circular segment area. Advantageously the spring lip only partially interacts with the lock holder in shape fit. Advantageously the fastening means only partially abuts the spring lip and other areas of the spring lip, usually of the radial extension of the spring lip, abut the lock holder.

In another variant of the invention, the lock holder is designed as a lock striker, having a first extension in the direction of the receptacle and at least one second extension perpendicular to the receptacle. If the lock holder is designed as a lock striker, there may be a plurality of areas of the lock holder for engagement with the fastening means. In this case, the extension of the lock striker perpendicular to the receptacle extends from the base plate of the lock holder, which extension is adjacent by the extension of the lock striker in the direction of the receptacle. In this way, the two regions of the lock holder can be engaged with the spring lip and / or fastening means. In this case, the first extension of the lock holder in the direction of the receptacle preferably has an extension in the direction of the axis of rotation of the locking mechanism. Thus, the first portion of the lock striker in the direction of the end of the receptacle may interact with the spring lip and the second region, ie the vertical region of the lock striker, may interact with the other portion of the spring lip.

In a variant, the region of the lock holder extending in the direction of the receptacle interacts with the spring lip in a shape fit. The region extending perpendicular to the receptacle extends substantially parallel to the axis of rotation of the locking mechanism, parallel to the end of the receptacle and parallel to a portion of the damper element disposed at the end. Advantageously the region of the vertically extending lock striker can interact formally with the fastening means at the spring lip. Indeed, in one embodiment, there may be interaction between the extension of the vertical lock striker and the fastening means of the spring lip. If the region of the vertically extending lock striker has, for example, a cylindrical structure, the cooperating shape of the spring lip can engage the lock holder. Preferably the lock striker is negotiated in engagement with the securing means of the spring lip in the main latching position.

Also the area of the lock holder extending vertically or perpendicular to the base plate of the lock striker preferably interacts with the locking mechanism, in particular the rotary latch, by the area extending vertically. By interacting with the pawl, the load arm of the rotary latch holds the lock striker in the main latching position. If the locking mechanism is unlocked so that the pawl is released from the rotary latch, for example by a release lever, the shape locking engagement of the spring lip, in particular the fastening means, acts against the opening movement of the lock holder. Although the movement of the lock holder has been described, the present invention is not limited thereto since the motor vehicle lock preferably moves relative to the lock holder. Preferably, but not exclusively, the lock holder is fixed to the body of the vehicle.

In an advantageous variant of the invention, the spring lip advantageously comprises a riser, in particular a ramp-like rise. The lamp of the spring lip, which extends above the spring lip in a ramp-like manner, acts against the securing means with a large force when the lock holder enters the receptacle, for example after being able to formally engage with the securing means or lock holder after passing through the rise. It is advantageous in that it exists. Advantageously the raised and / or recessed portion can be formed integrally with the spring lip. Because of the ramped rise, there is a minimum stress on the spring lip because a large load acts on the spring lip, which increases the resistance of the spring lip to long-term stresses. Especially in the case of the interaction between the spring lip and the damper element, a large load can be applied to the spring lip to ensure reliable operation of the spring lip over the operating life of the lock. The engagement of the lock holder and the movement of the riser in the fastening means make it possible to achieve the maximum counter force simultaneously during unlocking.

In fact, the raised portion may be formed such that the spring lip can be latched with a lock striker or lock holder. In particular, the form of the latching means as a means for interacting with the lock holder makes it possible for the spring lip and in particular the fastening means to generate large forces as opposing forces when opening the lock. Preferably the latching means abuts a part of the lock holder in the opening direction, ie countering the movement of the lock on opening. In this case, the spring lip may be integrally formed with the lock housing. The integral structure of the fastening means and the spring lip facilitates the manufacture of the lock and reduces the number of components required. In particular, if the spring lip is formed of a plastic material, in particular the locking housing is formed of an injection molded part of plastic material, it is inexpensive to integrate the fixing means on the spring lip.

It is further advantageous if the spring lip can be formed at least partially as a separate component. This may allow the spring lip and / or fastening means to be placed in the car lock as separate components. In this case, separate components can be mounted, for example, in the lock housing, to allow for elastic deformation of the damper element and the spring lip. Of course, the spring lip and the fastening means are integrally made, for example from metal, in particular spring steel, so that the spring lip and the fastening means interact with the lock holder as a single component. It may be considered to be mounted in the housing of the vehicle. Preferably the spring lip and the fastening means interact with the damper element.

Advantageously the spring lip is at least partly formed from a wear resistant material, in particular a metal material. If the spring lip and / or fastening means are at least partly formed of metal (of course, a synthetic material consisting of a metal spring lip with an overmolded plastic area to form the fastening means may be considered), This can be combined with the advantages of durability and high elasticity.

In the following, with reference to the accompanying drawings, the present invention will be described in more detail based on the preferred embodiment. However, the exemplary embodiments do not limit the present invention, but merely illustrate one embodiment. The features shown may be implemented individually or in combination with the description and the individual features or combinations of other features of the claims.

1 is a perspective view of a receptacle or insert in the area of the spring lip, in particular as part of an automobile door closer.
2 is a side view of the spring lip according to the invention of the region of the receptacle, with the lock striker in the main latching position.
3 is a lock striker viewed along arrow III of FIG. 2.
4 is a lock housing, in particular a receptacle viewed from the direction of arrow IV of FIG. 1.

1 shows a part of a motor vehicle lock 1. Only a portion of the spring lip 6 arranged in the region of the lock housing 2, the damper element 3, the locking mechanism component shaft 4, the receptacle 5 and the receptacle 5 is shown. Other components of the motor vehicle lock 1 are not shown for clarity in illustrating the invention.

The receptacle 5 comprises an input 7 and a termination 8.

The damper element 3 is arranged at the end 8 of the receptacle 5, in which the damper element forms a stop means 9 to limit the movement of the lock holder 10, and the spring lip (6) It has an extension part 11 extended below. The damper element 3 may be designed as an opening or may further comprise an opening 12, which may for example be filled with an additional damper element (not shown). The circular rise 13 in the lock housing can be used, for example, to fix the position of a loader latch (not shown).

The fastening means 14 are formed integrally with the spring lip 6. The fastening means comprise ramped rises 15 raised at the end 16, allowing the interaction between the fastening means 14 and the damper element 3.

The spring lip 6 starts at the input 7 and faces towards the end 8 so that the spring lip 6 can engage the lock holder 10 at the main latching position H of the lock holder 10. It is formed to rise.

As clearly shown in FIG. 2, the area 17 of the lock holder 10, in particular of the vertically extending lock holder 10 abuts the spring lip 6 and the fastening means 14. Thus, a force is applied to the lock holder 10 by the spring lip 6 and in particular in cooperation with the damper element 3. If the spring lip 6 acts preferably in the direction of the axis H, ie in the direction perpendicular to FIG. 2, an additional force F can be applied to the lock holder 10 by means of the fastening means 14. have. Since exerting a force through the spring lip is known in the prior art, only the force F generated by the fastening means 14 is shown in FIG. 2. However, as clearly shown in FIG. 2, the force F acts opposite to the opening movement B of the lock holder 10.

If the lock holder 10 is released from the locking mechanism (not shown), the lock holder 10 should move in opposition to the force F. As a result, the load on the locking mechanism is reduced. Therefore, the opening noise can be reduced when unlocking the locking mechanism. In particular the counter force F acts against the force acting on the lock holder 10 by means of a locking mechanism and a seal of the door or hatch, for example.

3 is a lock holder 10 and a receptacle 5 viewed along arrow III of FIG. 2. As clearly shown in FIG. 3, the fixing means 14 abuts the lock holder 10. In this embodiment, the cylindrical region 18 of the lock holder 10 extends from the base plate 19 towards the motor vehicle lock 1, which cylindrical region 19 interacts with the fastening means 14. The vertically extending area 17 at least partially abuts the spring lip 6. The lock holder 10 is thus held in place in the main latching position H by the locking mechanism, the spring lip 6, the fastening means 14 and the damper element 3.

4 is a lock housing 2 viewed from the direction of arrow IV of FIG. 1. The receptacle 5 is shown here without the lock holder 10. The spring lip 6 is shown to be integrally formed with the lock housing 2, and the ramp-shaped lift 15 can be connected in shape to the lock holder 10. The shape of the fastening means 14 in the region of the insertion opening 5 or the receptacle for the lock holder 10 thus exerts an additional force F on the lock holder 10 so as to influence the opening noise, and In particular, it can positively influence the opening noise.
