Description

Automobile lock

Technical Field

The invention relates to a vehicle lock having a locking mechanism comprising a rotary claw and at least one pawl, wherein the rotary claw can be locked in a locking position, in particular a pre-locking position and/or a main locking position, by means of the pawl, and further comprising a reinforcement, wherein the reinforcement can be arranged between two housing parts and forms a rotational axis for a component which is pivotably arranged in the vehicle lock.

Background

More and more functions are added to the present motor vehicle, which on the one hand constitute a safety function and on the other hand increase the comfort of the motor vehicle user. The existing functionality and comfort functions determine that a large number of components are required to shape the vehicle function. In particular with regard to motor vehicle locks, today functionalities such as power locking, child protection, power opening and/or power opening of vehicle doors are known. These functions determine the addition of components, which in turn increases the weight of the vehicle lock.

However, the automotive industry is also pursuing a reduction in the weight of the motor vehicle, on the one hand in order to reduce the consumption of the motor vehicle, and on the other hand without the price of increased space requirements for vehicle components for the existing functionality. There is therefore a strive to obtain a car that is equipped with high functionality, better comfort and at the same time light weight. All these prerequisites must be sufficiently available, while at the same time a sufficiently high level of safety must be provided for the user, in particular in connection with safety-relevant vehicle locks.

DE 2 001 635 discloses a motor vehicle door latch, in which a reinforcement is used in the pocket carrier, the reinforcement of the pocket carrier simultaneously performing a plurality of functions. The reinforcement is formed in the form of a pivot pin and connects the housing to the cover. The reinforcement is formed in the form of a pivot pin and therefore also serves as a bearing shaft for the locking element. Thus, a high degree of security of the vehicle lock can be ensured, wherein the rotation pin simultaneously serves a dual function, so that the number of required components can be reduced.

A similar reinforcement in a car lock is disclosed in DE 20 2011 004 407 U1. The rotary claw transfer pin is then connected to the lock groove box in such a way that the rotary claw transfer pin can simultaneously carry, support and position the locking element. Furthermore, the rotary claw transfer pin is inserted into the lock housing and thus stabilizes the lock housing made of plastic.

The prior art is not convincing in all respects. In particular, the numerous metal components, although responsible for different functions, which make the assembly extremely complex, can make the resulting automotive lock heavy. The invention is addressed herein.

Disclosure of Invention

The object of the invention is to provide an improved vehicle lock. The object of the invention is, in particular, to provide a lock which is highly functional, simple to assemble and lightweight. The object is also to provide a structurally simple and cost-effective solution for a pivotable vehicle lock part mount.

This object is achieved by the features of the independent claim 1. Advantageous embodiments of the invention are specified in the dependent claims. It is to be noted that the embodiments described below are not limitative, but rather any possible variation of the features described in the description and in the dependent claims is possible.

The object of the invention is achieved according to claim 1 by providing a vehicle lock with a locking mechanism comprising a rotary pawl and at least one pawl, wherein the rotary pawl can be locked in a locking position, in particular a pre-locking position and/or a main locking position, by means of the pawl, and further comprising a reinforcement, wherein the reinforcement can be arranged between two housing parts and forms a rotational axis for a component which can be rotatably mounted in the vehicle lock, wherein the reinforcement can be pushed into between the housing parts. With the design of the motor vehicle lock according to the invention and in particular the reinforcement which can be pushed into the housing, the possibility is now provided that the reinforcement of the lock housing can be provided with a high degree of structural freedom and ease of installation.

By pushing the reinforcement between the two parts of the lock housing of the motor vehicle, a "point-like" increase in the stability of the lock housing and thus of the motor vehicle lock can be produced. In particular, one or more reinforcements may be provided in the vehicle lock, which may allow the housing to be reinforced in the form of points and/or in the form of faces. If on the one hand a reinforcement can be produced, said reinforcement can ensure a high degree of structural freedom by means of the reinforcement according to the invention.

In particular, since the reinforcement is only inserted into the plastic housing of the lock after the housing has been machined, sufficient space is available for the installation of further components, so that also relatively complex associated components can be inserted into the housing. The reinforcement or stiffening of the lock housing at the location of the highest load to be applied to the lock can be achieved by an additional or at least sequentially predetermined installation process of the vehicle lock.

If a vehicle lock is mentioned within the scope of the invention, all locks which are mounted in the vehicle and are movable on the vehicle or can be coupled to the vehicle in places where the vehicle component must be held securely during driving operation are included here. It is conceivable to mount the vehicle lock in a door, sliding door, hood, roof and/or cover, to mention a main field of application by way of example.

Here, the vehicle lock of the present invention includes a locking mechanism composed of a rotary pawl and a pawl. The rotary jaw and the at least one pawl are arranged in a plane, wherein the second pawl can also be arranged in a plane parallel to the rotary jaw and can, for example, cooperate with a bolt and/or a cylindrical pin on the rotary jaw. The rotary pawl now engages with a locking pin, which is fixed, for example, to the vehicle body. If the vehicle lock is installed in a side door, for example, the locking pin moves the rotary claw to a locking position when the door is closed, in which the pawl holds the rotary claw in the locking position. In the case of the side door, the formation of the pre-lock position and the main lock position is defined herein. In the case of a vehicle lock, for example, in a rear seat, it can now be activated with a single main locking position.

The reinforcement is then arranged in the housing of the vehicle lock in such a way that the two spaced apart planes of the vehicle lock are connected to one another. In this case, it may be two separate interconnected components such as a housing shell and a housing cover. The lock housings of modern motor vehicles are preferably made of plastic. A motor, switch, lever, damper, gear and/or slide are disposed within the housing. The housing serves in this case on the one hand for supporting the components and also for protection against the ingress of moisture and/or dust. The formation in the form of a support for another component brings the advantage that the reinforcement can comprise a number of functions. If the reinforcement is used on the one hand for the reinforcement of the housing, the reinforcement can at the same time be used, for example, as a bearing point for an actuating lever in a vehicle lock.

In a variant embodiment of the invention, the reinforcement can be held between the housing parts in a form-fitting manner. The reinforcement being received in a form-fitting manner in at least one of the housing parts simplifies the mounting, wherein it can be designed, for example, to lock the reinforcement in the housing. It is also conceivable here for the reinforcement to be engaged into the lock housing via guide rails. It is also conceivable that: a tongue-and-groove connection can be produced between the reinforcement and the lock housing, so that the lock housing is stabilized solely by the reinforcement being inserted into the lock housing. It is also conceivable according to the invention that a friction-fit connection and/or a material-bonded connection can be established between the reinforcement and the housing part. The reinforcement can thus be inserted into the housing, for example, in a form-fitting manner and held in the mounting position in a friction-fitting manner. For the material-bonded connection, the housing can be heat deformed, for example.

A further advantageous embodiment results when the housing can be designed in one piece and preferably consists of plastic. When the housing is formed in one piece, it is often the case that the distance between the opposite housing walls varies due to machining tolerances. By incorporating the reinforcement, in addition to reinforcement, the housing shape can be supported and maintained, so that the spacing can be set by means of the reinforcement fixing structure. In addition to stiffening or strengthening and utilizing many functions, the reinforcement may thus also serve as a spacer and/or a fixing for the housing.

A further advantageous variant of the invention results if the reinforcement has a through-hole and the reinforcement can be held in the housing by means of a cylindrical pin. The reinforcement provides the possibility of additionally reinforcing the housing by means of a cylindrical pin, preferably by means of a cylindrical pin consisting of a metallic material, for further stabilization. In addition to the reinforcement of the housing, the load-bearing capacity of the reinforcement as a bearing shaft can be increased by the cylindrical pin. The cylindrical pin on the one hand reinforces the reinforcement part made of plastic, while extending through the housing parts spaced apart by the reinforcement part. It is thus possible, on the one hand, to support the reinforcement and, on the other hand, to obtain a further stabilization and reinforcement of the lock housing.

The cylindrical pin can be designed, for example, in such a way that it can be positively connected to a hole in the reinforcement, so that a fixed bearing point can be established by the reinforcement. By the positive fit reception of the cylindrical pin in the reinforcement and/or in the lock housing, the reinforcement can be received in the lock housing in a positionally stable and rotationally fixed manner.

It is also conceivable, for example, for only the cylindrical pin to be held in a form-fitting and fixed manner in the housing part and for the reinforcement to be held on the cylindrical pin in a clearance-fitting manner, so that a seat for the reinforcement can be formed. The reinforcement can then in this embodiment be accommodated in the lock housing, for example, rotatably about the cylindrical pin. It is also conceivable for the cylindrical pin to project out of the lock housing at least on one side and to be accommodated in the lock housing, for example, in a form-fitting manner by means of a spring ring.

In a variant embodiment, the cylindrical pin can be formed in the form of a stepped pin. If the cylindrical pin has different diameters in its axial extension, it is possible to axially guide a plurality of components guided for movement on the stepped pin. In particular, the reinforcement itself can be formed in multiple parts, for example. If the reinforcement is for example made of two component parts, the two different parts of the reinforcement can be moved over the step core and held in place. A design in the form of a stepped pin can also be used to fix the stepped pin itself in position in the housing part.

The installation locking mechanism can be produced, for example, in such a way that different diameters are provided in the lock housing for accommodating the cylindrical pin. Therefore, the cylindrical pin can be mounted in only one direction, and mounting errors can be inhibited. By designing different diameters, the stiffness can also be influenced at the stiffener. If the reinforcement is used, for example, for supporting an operating lever which is subjected to high forces, the design of the cylindrical pin with a large diameter advantageously supports the operating mechanism.

A further variant embodiment of the invention results if the cylindrical pin has at least one rivet head, wherein the cylindrical pin can be connected to the housing in an inseparable manner by means of the rivet head. By forming a rivet head on one end of the cylindrical pin, an inseparable connection can be established. In particular, it is ensured that the reinforcement element is held securely in position on the stud pin. Further stabilization of the housing parts is possible by riveting of the cylindrical pins, so that the reinforcement can be held in a press fit between the housing parts. This ensures a play-free mounting of the component fastened to the reinforcement. Thus, a reliable positioning of the operating mechanism on the reinforcement is ensured by riveting and at the same time a high stability of the housing is obtained.

In one embodiment of the invention, the reinforcing elements have different diameters, wherein at least two receptacles, in particular bearing shafts, for the lock components can be formed. The different outer diameters of the reinforcement elements may hold the operating mechanism securely and in place on the reinforcement elements. It is therefore also conceivable for several actuating devices, for example two pivotable levers, to be mounted on the reinforcement, wherein a positionally stable positioning of the levers can be achieved by designing different diameters. In this case, on the one hand, installation reliability can be ensured, since incorrect installation can be prevented by different diameters, while at the same time the spacing of the pivotably mounted components on the reinforcement can be achieved by designing different diameters. Furthermore, a high stability at the bearing shaft can be ensured by different diameters or provided for the operating mechanism.

It is also conceivable that the reinforcement has on the one hand a uniform circular diameter and that the other step of the reinforcement has, for example, a shape with a non-circular diameter, so that a form-fitting retention of the component on the reinforcement is possible. The reinforcement can have an oval, polygonal or star-shaped outer surface at least in sections, onto which the components of the vehicle lock can then be pushed. This can be advantageous, for example, if the reinforcement is accommodated with play in the housing, so that the reinforcement allows the component to bear on the cylindrical pin.

Advantageously, the reinforcement is made of plastic. The construction of the reinforcement from plastic brings the advantage that a high degree of design variability is possible during manufacture, while at the same time a lightweight reinforcement can be formed. Furthermore, the reinforcement composed of plastic can provide good sliding properties for the member swingably held on the reinforcement.

One receptacle of the reinforcement forms a bearing axis for the operating lever, in particular the inner operating lever. The operating lever forms a link in the operating chain between the inner door handle and the outer inner handle for unlocking the locking mechanism. At this time, the bowden cable is operated, for example, by the outer door handle, which in turn engages with the outer operating lever and directly disengages the pawl from the rotary jaw by the release lever. In order to interrupt the operating chain, a locking system can be provided, which interrupts the operating chain, so that the operation of the inner or outer operating lever can be disengaged from the release lever. The reinforcement preferably forms a bearing axis for the inner operating lever.

The other receptacle on the reinforcement advantageously forms a receptacle for a spring element which cooperates with the operating lever. The reinforcement thus also forms a receptacle for the other lock component, which serves for the positional fixing of the component in the vehicle lock. Advantageously, the spring element, preferably a leg spring, engages the operating lever in such a way that the operating lever can be biased in the operating direction. Thus, in cooperation with the lock housing, a spring force can be applied to the operating rod. In addition to the four functions of the reinforcement, such as reinforcement, fixing of the shell spacing and accommodation of a plurality of lock components, the functionality of the vehicle lock can be increased, wherein the small floor space requirement and the low weight caused by the reinforcement are brought to the vehicle lock.

Drawings

The invention will be described in detail below with reference to the accompanying drawings in conjunction with preferred embodiments. It is basically true that the exemplary embodiments of the invention are not restrictive, but merely represent advantageous embodiments. The features shown may be described individually or in combination in the description, or with other features of the description and the claims. Wherein:

FIG. 1 is an isolated view of a cylindrical pin in the form of a stepped pin and a reinforcement made of plastic with through holes, an

FIG. 2 is a perspective view of an automotive lock housing having a reinforcement member incorporated therein.

Detailed Description

Fig. 1 shows a cylindrical pin 1 and a reinforcement 2 as separate components. The cylindrical pin is then made of a metallic material, in particular steel, and the reinforcement 2 is formed in the form of a plastic part.

The cylindrical pin 1 has a set of different diameters, so that the cylindrical pin 1 is in this embodiment constructed in the form of a stepped pin, more preferably in the form of a riveted stepped pin. The first bearing surface 3 serves as a bearing surface against the wall of the lock housing, wherein the cylindrical pin 1 can be inserted into the lock housing and bears with the bearing surface 3 against the outer surface of the lock housing. The other diameter on the cylindrical pin 1 forms a first step 4 on which the reinforcement 2 can be fitted. The first step is thus used for the positional positioning of the reinforcement 2 on the cylindrical pin 1. The second step 5 also forms a bearing surface for the reinforcement 2. The third step 6 of the cylindrical pin 1 is only passed through by the end 7 of the cylindrical pin 1, where the end 7 of the cylindrical pin 1 protrudes out of the lock housing. The end 7 of the cylinder pin 1 forms a rivet head 7 for the non-detachable connection of the cylinder pin to a lock housing 8 shown in fig. 2.

The reinforcing elements 2 also have different diameters, so that the reinforcing elements 2 are also formed in a stepped manner. The first diameter 9 then forms a bearing surface for a not shown actuating rod that can be supported on the second diameter 10. The other third diameter 11 in turn serves as a bearing surface for another lock component that can be received on the fourth diameter 12. Finally, the reinforcement 2 has a fifth diameter 13 which cooperates with guide ribs in the lock housing 8.

The reinforcement 2 is of hollow cylindrical design, wherein a bore 15 or opening 15 is provided in the reinforcement, wherein the bore 15 is formed such that the cylindrical pin 1 can be inserted into the reinforcement 2 and the plurality of steps 4, 5, 6 of the cylindrical pin 1 correspond to the bore 15 in the reinforcement 2. Thus, the holes 15 have different sizes within the reinforcement 2. The first diameter 9 serves on the one hand for axial stabilization of the rod resting on the second diameter 10, so that the first diameter 9 can also serve with the ribs 16 for guiding and/or positioning the reinforcement 2 in the lock housing 8. The first diameter 9 can thus perform a number of functions.

Fig. 2 shows a perspective view of a lock housing 8 made in one piece from plastic. The lock housing has two spaced apart

outer walls

17, 18. The reinforcement is pushed between the

lock housing parts

17, 18. At this point the reinforcement 2 is aligned by means of guide or

positioning ribs

14, 16 in the lock housing 8, so that the cylindrical pin 1 can be guided along the axis a through the reinforcement 2 and the

lock housing walls

17, 18. After the cylindrical pin 1 has been inserted into the lock housing 8 and through the reinforcement 2, the rivet head 7 can be riveted, so that a fixed connection can be established. The reinforcement 2 is then connected inseparably to the lock housing.

On the second diameter 10 of the reinforcement 2, for example, an inner operating rod can be mounted. The inner operating lever may have an arm or extension which passes through the recess 19 so that, for example, a lever mounted on the inner operating lever may be connected to an operating lever supported on the second diameter 10. The inner actuating lever is then pivotably supported on the reinforcement 2 via the second diameter 10.

The fourth diameter 12 serves in this embodiment to accommodate a belleville spring which cooperates with an operating rod supported on the second diameter 10. The operating lever and the leg spring can then be received and supported on the reinforcement 2. In an advantageous manner, a support point which is easy to install, offers a high degree of structural freedom and is not massive is provided by the invention in the vehicle lock 20.
