EP2643537B1 - Lock module for a motor vehicle - Google Patents

Description

The invention relates to a door of a motor vehicle with a built-lock module with the features of the preamble of claim 1, for example, known from the document DE 195 24 568 A1 as well as an assembly process. The lock module is usually installed in a motor vehicle door, in particular a motor vehicle side door.

From the DE 195 24 568 A1 is a motor vehicle door lock called lock module, which includes closing elements, a locking lever system, acting on the closing elements operating lever system and an outside handle. The closing elements comprise a catch of catch and pawl. The locking mechanism is part of the lock for a motor vehicle.

A rotary latch of a motor vehicle lock has a fork-shaped inlet slot, into which a locking bolt of a vehicle door or a vehicle door, when the vehicle door or vehicle door is closed. The locking pin then rotates the catch from an open position to a closed position. If the catch has reached a closed position, then the locking pin can not leave the inlet slot of the catch. In the closed position, a pawl locks the catch, so that it can not be rotated back into the open position.

A motor vehicle lock includes not only moving parts such as a rotary latch and pawl but also parts that are not moved when installed. These include a usually metallic lock plate, rotatably attached to the catch and pawl are. A lock may further comprise an existing plastic housing, which may be closed with a lid.

There are locks for a motor vehicle with two closed positions, which can be taken in succession during the closing of the rotary latch, namely the so-called Vorrast and the so-called main catch. In order to increase the comfort, a drive and in particular an electric drive can be provided with which a rotary latch is moved into the main latching position after reaching the pre-latching position. Such a drive comes from the unpublished German patent application 10 2009 026 921 out. A lock with such a drive is called a servo lock.

It is also on the pamphlets DE10354854A1 . DE10304203A1 . WO02 / 28672A1 . GB2253435A and DE102005044109A1 referenced, which also reveal door locks for doors of motor vehicles.

The aforementioned features may be part of the present invention individually or in combination.

In the not previously published German patent application DE 2010 003 409 It is described that the assembly cost has increased over time, which is associated with the installation of modules in a motor vehicle door, especially in the case of the installation of modules in motor vehicle side doors. Built-in modules can be window regulators, motor vehicle door locks, loudspeakers, actuators for closing / opening devices. One of the reasons for the increasing installation effort is that the number of modules and other components such as side impact protection has increased, so that space problems have increased. In addition, the variety of vehicle doors has increased, which has also increased the requirements for installation.

Against this background, it is an object of the invention to provide a door with a lock module, which is able to contribute to reduce assembly costs.

To achieve the object, a door of a motor vehicle with a lock module installed therein comprises the features of claim 1. Advantageous embodiments emerge from the subclaims.

• Betätigungshebelsystem,
• Verriegelungshebelsystem,
• Griffmodul mit einem Öffnungsgriff, insbesondere Außenöffnungsgriff.

The lock module with a catch of pawl and rotary latch, in particular servo lock, and an electric drive for the lock, particularly preferably for the servo lock, may comprise components which are selected from:

• Actuating lever system
• Locking lever system
• Handle module with an opening handle, in particular outer opening handle.

The lock module comprises at least the drive, which is movably mounted. The drive can therefore be moved relative to the other one or more components of the lock module.

It is already known to provide the aforementioned components with movable elements. Thus, a lock comprises a plurality of movable elements such as a rotary latch, one or more pawls for latching the catch in the pre-latching position or in the main latching position, one or more blocking levers for blocking a pawl latching the latch. An opening handle is movably mounted on at least one other part of the handle module. This movable attachment of individual elements of a component serve to operate a lock module. Thus, the locking mechanism requires moving parts to close a door. The mobility of a handle is used to open a door.

In contrast, the movable mounting of the drive relates to a movable connection, which is not moved during operation in the installed state. According to the invention, the movable connection in the installed state of the lock module can not be moved, because the drive has been fixed by the installation and therefore can not be moved. The mobility then refers only to the case that the lock module is not installed in a door.

The movable attachment can overcome Einbauschwierigkeiten. The mobility can be used to facilitate the actual installation. At the beginning of an assembly, the drive then assumes a different spatial position or arrangement relative to one or more further components of the lock module in comparison to the spatial position or arrangement which the drive assumes in the installed state relative to other components of the lock module. The movable attachment can be used to adapt the lock module to different installation situations. In a first type of door, the drive then occupies a different position relative to one or more other components of the lock module as compared to installation in another type of door.

According to the invention, the drive for the lock is movably connected to the lock, preferably with the housing, particularly preferably with the lid of the lock. The desired movable attachment can be achieved structurally particularly simple. Particularly preferably, the drive is spatially separated by means of a web connection from the castle.

The movable connection may be or include a flange connection. The drive has then been flanged. The desired connection can be realized in a technically particularly simple manner.

Preferably, the movable connection can be locked and / or comprises latching elements for latching the connection. This further contributes to ease of assembly. Thus, a lock module can already be supplied by a supplier for installation in a door so that the drive already at the beginning of an assembly occupies the position that should take the drive at the beginning to facilitate the installation. The locking and / or the locking elements ensure that the initial position is initially maintained. By loosening the lock can then be changed if necessary, the arrangement of the drive in a manner necessary for the completion of the assembly. The locking elements or the associated locking connection is preferably such that an increased force is sufficient to change the arrangement of the drive relative to other components in the desired manner.

In one embodiment, locking and / or locking elements are such that can be locked and / or locked only according to predetermined arrangements. It can be avoided so incorrect intermediate positions or arrangements of the drive relative to other components of the lock module, which would interfere with the installation.

In one embodiment, the drive is connected via a flexible Bowden cable with the lock, so as to move an element of the castle, so to drive. The Bowden cable is a typical element for such a drive and in particular in the case of a spatially separated arrangement. Therefore, the drive is particularly suitable for a movable attachment, so as to facilitate installation significantly.

In particular, the drive serves to move the catch from a pre-latching position to a main latch position, thereby increasing the convenience of closing a door.

According to the invention, the drive is an electric drive and preferably comprises an electric motor or a shape memory alloy, ie an alloy which is able to change its shape abruptly as a result of temperature change.

The lock comprises in one embodiment a first pawl for locking the catch in the pre-engaged position and a second pawl for locking the catch in the main latching position. But it can also satisfy a pawl, which is able to lock the catch both in the pre-locking position and in the main locking position.

In one embodiment, the lock comprises a blocking lever which is able to block the pawl in its detent position.

In one embodiment, it is a self-opening ratchet with a blocking lever. This is to ensure that the locking mechanism is able to open independently when the blockade is lifted by the blocking lever.

The invention will be explained in more detail with reference to a figure showing a lock module.

The FIG. 1 shows a lock module with a servo lock 1, an electric drive 2 for the lock 1 and a handle module 3 with handle plate 3a and handle 3b. The drive 2 is rotatably mounted on the servo lock 1 with a web 4. The servo lock comprises a lock plate 1 a, a lock housing 1 b and a lock cover 1 c. The rotatable connection between the Servo lock 1 and the electric drive 2 is provided with locking means which allow a latching in at least two different positions. In general, two different locking positions are sufficient to facilitate installation significantly. Therefore, it is even preferable that can be locked or engaged only in two different positions, so that only two different latched and / or locked arrangements of the drive 2 relative to the servo lock 1 are possible. Operating errors are thus reduced regularly. It is therefore not possible due to the limited number of locking positions or locking positions, to lock or lock continuously and thus not in an advantageous manner.

With the aid of a Bowden cable 5, the drive 2 arranged spatially away from the lock 1 is able to move the catch of the lock 1 from its pre-locked position into its main locking position. Due to the remote arrangement, the drive can be arranged in areas of a door that are not otherwise required. The web connection 4 makes it possible to deliver the lock module in the finished pre-assembled state despite spatial separation of drive 1 and lock 2 for final assembly in a door.

Although, for example, the handle module 3 with the lock 1 could alternatively or additionally be connected rotatably in order to facilitate installation. However, it has been found that it is particularly important to connect a drive 2 rotatably. In fact, handle 3 and lock 1 must always assume a predetermined position in a door. The spatial arrangement of a drive, however, can be selected or specified comparatively flexible. A significant advantage is therefore achieved by the inventive rotary attachment, which is able to follow the flexible Bowden cable.

For the above reasons, it is therefore to be preferred that the handle 3 is rigidly connected, for example via a web 6, to the lock 1, since in this respect it regularly arrives at an exact position relative to one another.
