Description

The present invention relates to a motor vehicle door lock having the features the preamble of claim 1.

The term of the motor vehicle door lock is to be understood comprehensively. There are not only side door locks and rear door locks, but also for example Tailgate locks covered by it. For the rest, the term motor vehicle door lock means the entire system, whose components are also distributed could be.

Motor vehicle door locks are known in a variety of embodiments. Motor vehicle door locks with central locking drive are increasingly being found. Opening drive, auxiliary closing drive, all electromotively driven. An example of this can be found in EP 0 894 920 A1. at This motor vehicle door lock are located on the closing elements and in the lock mechanism a variety of micro switches, partially designed as non-contact sensors, in particular Hall sensors whose signals be evaluated and implemented in a lock electronics.

Especially with the lock mechanism and the lock electronics is the question of Moisture entry of importance. The previously explained, known motor vehicle door lock here meets special measures of shielding.

A motor vehicle door or flap has a door outer wall facing Moisture, in the top of the window shaft moisture in frequently not inconsiderable amount occurs, and one of them separate and against usually sealed drying room, directed to the inside of the vehicle door or flap. In the wet room necessarily sit the closing elements, the are usually located on the front side of the vehicle door or flap. In the drying room are electrical components and facilities, such as Speakers etc. A wet room / dry room separation is for example already known for power windows.

In the prior art from which the invention proceeds (DE 44 44 581 Al) is a wet room / dry space separation for a motor vehicle door lock he follows. In this known motor vehicle door lock is provided that the mechanical locking elements, also lock latch and pawl, in one Closing unit are combined in an encapsulated housing, which in Moisture is arranged. In the dry room, however, sits, over Bowden cables connected to the clamping unit, which in turn separated control unit with electric drive motor and lock electronics. Also sitting in the drying room a door interior handle assembly. The use of a distance power transmission means as a Bowden cable, the wet / dry separation of the vehicle door or flap permeated, it allows the moisture-sensitive To accommodate the control unit in the drying room, without the proper functioning of the Total vehicle door lock to affect.

From a non-prepublished patent application (DE 100 57 007.0) is the Proposal, the concept of wet / dry separation continues to complete that an outside door handle assembly with an outside door handle and a lock cylinder by means of a removal force transmission means, in particular a Bowden cable, not with the closing unit, but mechanically connected to the control unit located in the drying room is. This results in an actuation of the closing element of the closing unit, in particular so the pawl, from the outside door handle assembly forth only the control unit. The control unit also contains the elements of the lock mechanism as well as central locking drive, anti-theft drive etc.

In the likewise not previously published patent application (DE 101 51 022.5) it is proposed necessary electrical connection elements between the Control unit and the clamping unit, for example, for supply or for Inquiry of sensors to integrate into the distance transmission means or to summarize this. In a particular embodiment is provided here that an electrical connection line as a kind of jacket wrapped around the Bowden cable, which represents the removal power transmission means is.

In the prior art, no less than five mechanical connections through distance transmission and a not shown number of electrical connection elements, in particular for the query and supply of sensors for scanning the Position of the lock latch o. The like., Required. In the further explained, not Prior published prior art applies in a similar manner. The so associated effort is significant and is a hands-on introduction this motor vehicle door locks against.

The invention is based on the object, the previously described known concept a wet room / dry space separation for a motor vehicle door lock to optimize.

The object indicated above is characterized by the features of the characterizing one Part of claim 1 solved.

It is essential that the information of reaching the closed position or the Main latching position of the lock latch mechanically via the distance transmission means is transmitted to the control unit. It is provided here that the movement of the latch in the closed position or the main latch position causes an actuation force on the removal force transmission means and that the resulting movement of the distance power transmission means in the control unit is evaluated circuit technology. This takes place by means of a pulling function of the distance-transmitting means in a first Direction of the operation of the closing element, in particular the pawl. By means of a train function of the distance-force transmission means in one second direction, opposite to the first direction, is reaching the Closed position or the main latching position of the latch can be mechanically signaled.

This ensures that the desired scanning of the position of the latch by an already existing connection element, namely the removal force transmission means, can be routed to the control unit. To a electrical connection element between closing unit and control unit can be waived in this respect.

Of course, there are a variety of ways to design the teachings of the invention and further education. For this may refer to the dependent claims become.

According to claim 2, the removal force transmission means with the closing element, here the pawl, coupled with the inclusion of a two-way freewheel. This allows the latch in already fallen pawl still a certain overstroke and possibly the pawl a lagging collapse when closing the motor vehicle door lock.

To reach the closed position or the main latching position of the latch by the movement of the distance-transmitting means in the control unit To be able to recognize as surely as possible, it is desirable that the to be recognized Movement of the distance transmission means substantially larger is than any inaccuracies caused by tolerances, etc. As a rule this movement will be much larger than the possible deflection the pawl, so that a correspondingly large freewheel are provided got to.

A large freewheel means, however, that in the closed position or in the main position located latch for lifting the pawl basically the existing freewheel must be "bridged". This is special against the background problematic that the actuating forces on the outside door handle and the door inside handle should be as low as possible, for maximum ease of use to ensure. These low operating forces can be in realize general by a corresponding translation, so that a small Operating force is "bought" by a large actuation stroke. It is obvious that against this background, the above-mentioned freewheel problematic is.

Claim 7 shows a solution, such as a large movement of the distance-force transmission means compared to the lifting movement of the pawl can be realized without having to take a freewheeling purchase. At in the closed position or the main latching position located latch causes an operating force on the distance-transmitting means immediately an actuating force on the pawl. The freewheel is controlled by an adjustable Intermediate element, which is motion-coupled with the latch, largely avoided.

Fig. 1 shows the basic concept of the present invention, namely a motor vehicle door lock with mechanical closing elements 1, 2, in particular one Lock catch 1 and a pawl 2, in a closing unit 3, which is here in a protected against ingress of moisture housing 4. Further 1 shows a lock mechanism 5, also indicated in a housing 6, Fig. 2 reveals that such a lock mechanism 5 regularly several having mutually cooperating elements. This arrangement forms one of the closing unit 3 spatially separated control unit. 7

The motor vehicle door lock shown schematically in Fig. 1 is the example a motor vehicle side door lock shown. Also hatchback locks, Sliding door locks, flap locks o. The like. Are of this concept of the door lock recorded and covered. On the above-mentioned state of Technique may be referred to for further explanation.

In Fig. 2 is already indicated that in the control unit 7 a lock electronics 8 may be located regularly on a circuit board in the housing 6 of the control unit 7 is used. If necessary, you will also find the necessary microswitches here, Sensors etc. their place.

Fig. 1 makes it clear that the closing unit 3 spatially spaced from the Control unit 7 is arranged in a motor vehicle door or flap 9, namely the closing unit 3 with the closing elements 1, 2 in the wet room on the front side the motor vehicle door or flap 9, the control unit 7, however, beyond the damp / dry separation 10 in the dry space of the motor vehicle door or flap 9.

The previously described distributed arrangement of the components of the motor vehicle door lock has the advantages explained above, in particular with regard to Moisture protection of the delicate mechanical elements of the lock mechanism 5 and the lock electronics 8.

Of course, because of the concentration of electrical components in the Control unit 7, the mechanical movement of the pawl 2 over the distance between the closing unit 3 and the control unit 7 are transmitted. This is used in the illustrated embodiment and so in the state of Technique a distance transmission means 11, here and after more preferred Execution in the form of a Bowden cable with a soul 11 '. Fig. 2 makes it clear that a corresponding pawl lever 12, the soul 11 'of the Bowden cable 11 moves to actuate the pawl 2 to the right, whereby the pawl second is dug. Of course, this only happens when the control unit 7 in remaining "unlocked" is so in function "unlocked" is.

Fig. 2 makes it clear how in the preferred embodiment, the inner life the control unit 7 may look like. Such a control unit 7 is in the not previously published prior art, which has already been mentioned above has already been used, in principle. One recognizes a Bowden cable 13, which leads to an outside door handle, one of this Bowden cable 13 from actuating external actuating lever 14 and a coupling element 15. A Central locking drive has an electric drive motor 16 and a Worm gear with a drive element drivable in two directions 17, here a worm wheel, on. The drive element 17 actuates in one direction an adjusting element 18 in the direction of a coupled position and the Bowden cable 11 to the pawl 2. In the opposite direction the adjusting element 18 is actuated in the direction of the disengaged position and the pawl 2 released.

Also provided is a Bowden cable 19 to a door inner handle, an anti-theft drive motor 20 with corresponding drive element 21 and a to belonging Kuppelzapfen 22. For this construction may otherwise on a referenced simultaneously filed patent application of the present applicant become.

Fig. 3 shows that the distance-force transmission means 11, so here the soul 11 'of the Bowden cable, at least in the closed position or, as provided here, the main locking position of the latch 1 is also connected to the latch 1. The achievement of the closed position or main latching position of the latch 1 is by utilizing the traction function of the distance transmission means 11, here, therefore, the soul 11 'of the Bowden cable, in the opposite direction in the Control unit 7 in mechanically signaled. The movement of the soul 11 of the Bowden cable in the opposite direction (in the second direction) to be evaluated in the control unit 7 circuit technology.

Technically, this means that a first position in the control unit 7 means that the pawl 2 is in its Einfallstellung. One on the other hand, slightly spatially spaced position of the end of the soul 11 'in the control unit 7 signals that now also the latch 1 occupied its closed position Has.

As a result, can here on an electrical connection element to the closing unit 3 be waived. The desired scanning of the position of the latch 1 can here mechanically using the already existing distance power transmission means 11, namely the soul 11 'of the Bowden cable reached become.

The illustrated and preferred embodiment shows that the soul 11 'of the Bowden cable with the closing element, namely the pawl 2 below Interposition of a pawl lever 50 or another intermediate element is coupled with the inclusion of a two-way freewheel 51. Of the two-way freewheel 51 allows the latch 1 still a certain lift, Moreover, the pawl 2 a lagging collapse when closing the Motor vehicle door lock.

The illustrated and preferred embodiment further shows that the Ratchet lever 50 o. The like. Pre-tensioned in a middle position by means of a spring 52 and upon reaching the closed position or main latching position of the latch 1 is deflected against the spring force. The predetermined by the spring 52 Middle position of the pawl lever 50 relative to the pawl 2 provides the position "pawl collapsed" dar. hits the latch 1 then on the Soul 11 'of the Bowden cable and moves them further down in Fig. 3, so the spring 52 is tensioned and the state "lock latch in the closed position" signaled.

The desired freewheel 51 can be in various constructive ways realize. For example, you can switch spring elements, which Divide soul 11 'of the Bowden cable, etc. The illustrated embodiment shows that the freewheel 51 simply by a slot-pin arrangement between the pawl lever 50 and the pawl 2 has been formed. Of the in Fig. 3 downwardly remaining path of the pin in the slot allows the Lock catch 1 a certain lift and also allows the trailing Collapse of the pawl 2.

The embodiment shown in Fig. 3 also shows a special Construction such that the soul 11 'of the Bowden cable with the latch 1 is detachably connected outside the closed position or main latching position. Therefore it is provided that the latch 1 a catch element 53 here in the form of the end one mounted on the latch 1 spring element 54 which has the end the soul 11 'of the Bodenzugs before reaching the closed position or Haupttraststellung einfängt and entrains in the position shown in Fig. 3. One recognises the spring element 54 designed as a leg spring on a stop 55, which specifies an end position. The coordinated spring forces of the springs 54 and 52 provide the desired switching and signaling function with respect to the closed position of the latch 1.

In the drawing, Figs. 4 and 5 show a further particularly preferred embodiment of the motor vehicle door lock. Here it is provided that the closing unit 3 has an adjustable transmission element 60 via which the removal force transmission means 11 connected to the closing unit 3 in the rest is. For this purpose, first, the transmission element 60 with the distance-force transmission means 11, in particular with the soul 11 'of the Bowden cable, connected. The lock latch 1 is also with the removal force transmission means 11, in particular with the soul 11 'of the Bowden cable, coupled via the transmission element 60.

At this point it should be noted that coupled with a connection, but in particular also a detachable connection can be meant. present coupled means that the removal force transmission means 11 at least in the closed position or the main latching position of the latch 1 via the Transmission element 60 is connected to the latch 1.

The adjustment of the latch 1 of the pre-locking position, not shown in the closed position or main rest position (FIG. 5) causes an adjustment of the Transmission member 60 in Fig. 5 down (position S1), whereby the removal force transmission means 11, in particular the soul 11 'of the Bowden cable is moved in the second direction. As will be shown below is, this connection between latch 1 and transmission element 60 a resilient connection, so that the transmission element 60 against the Restoring force of this resilient connection by a corresponding operation of the distance-force transmission means 11 in Fig. 5 upwards, ie in the first direction, is adjustable.

The said adjustment of the transmission element 60 in the first direction causes the lifting of the pawl 2 via a transmission element 60th associated intermediate element 61. For this purpose, the intermediate element 61 a Contact surface 62, which by the adjustment of the transmission element 60 in the first direction to a corresponding contact surface 63 of the pawl 2 comes into contact.

If now the contact surface 62 of the intermediate element 61 would be rigid on the transmission element Arranged 60, so should in the closed position or in the main position located latch 1, the transmission element 60 a certain movement in the first direction (freewheel) to the contact surface 62 of the intermediate element 61 in abutment against the contact surface 63 of the pawl 2 would come. Around To avoid this freewheel, in a particularly preferred embodiment that Intermediate element 61 on the transmission element 60 configured so adjustable, that the distance of the contact surface 62 of the intermediate element 61 to the contact surface 63 of the pawl 2 is adjustable. This one becomes constructive adjustability realize so that an adjustment takes place in such a way that always a minimum distance between the contact surfaces 62, 63, up to the distance "Zero", ie the plant itself, is realized.

With the distance between two contact surfaces is meant here the distance, which must be bridged, so that the two contact surfaces together in Appendix come. It is not necessary that it is flat contact surfaces is. Rather, it can be provided that the one contact surface by a pin o. The like. And the other contact surface by a control cam, an edge o. The like. Is formed. In the present case it is the case that the intermediate element 61 a formed in cross section as a cam contact surface 62 and the Pawl 2 a formed by a radius, in particular by a pin Contact surface 63 has.

Furthermore, the latch 1 and the adjustable intermediate element 61 are coupled in a movement-coupled manner in this way, that the adjustment of the latch 1 of the pre-locking position in the closed position or in the main latch position an adjustment of the Zwischenelemerits 61 causes. This motion coupling is now configured in such a way that the contact surface 62 of the intermediate element 61 at least when reaching the Closed position or the main latching position in contact with the contact surface 63 of the Pawl 2 comes. This ensures that when in the closed position or in Main locking position of the latch 1 is an operation of the distance-force transmission means 11 in the first direction immediately and without intermediary Freewheel actuation of the pawl 2 causes.

The above advantages are achieved in particular by the fact that the transmission-effective distance between transmission element 60 and pawl 2 is adjustable by the adjustment of the intermediate element 61. With transmission effective distance is in this case the distance in the adjustment of the transmission element 60 between a fixed point on the transmission element 60 and the respective force application point of the transmission element 60 meant at the pawl 2.

The movement coupling between latch 1 and intermediate element 61 is in particularly preferred embodiment realized that on the one hand the latch 1 has a control edge 64 and that on the other side of the Intermediate element 61 a corresponding engagement element 65, preferably a pin o. The like. Has. When adjusting the latch 1 in the closed position or in the main position comes the control edge 64 of the latch 1 in contact with the engagement member 65 and adjusted accordingly.

A simple and robust embodiment of the intermediate element 61 results when the intermediate member 61 as a lever 66 pivotable about an axis is designed. The abutment surface 62 of the intermediate member 61 is so on the lever arranged that by the pivoting of the lever, the distance of the contact surface 62 to the contact surface 63 of the pawl 2 is adjustable. In the simplest Embodiment is on the intermediate element 61 a wedge-shaped or stepped in cross-section Element 67 arranged. In the wedge-shaped embodiment, the Element 67 a base and an inclined surface, wherein the base in is arranged substantially tangentially to the axis 66 and the inclined surface of the Contact surface 62 forms. By pivoting the intermediate element 61 leaves the wedge-shaped element 67 depending on the position of the transmission element 60th "under" the contact surface 63 of the pawl 2 push. In the step-shaped Embodiment, however, forms a step on the element 67, the contact surface 62 of the Intermediate lever 61, in turn, under the contact surface 63 of the pawl second can be pushed. In Fig. 5, the state is shown, in which the Stage of the element 67 is located below the contact surface 63 and to this in Appendix is.

Depending on the configuration of the contact surface 62 of the intermediate element 61 has Intermediate element 61 a suitable adjustment. In a preferred Embodiment is therefore on the transmission element 60 and / or on the intermediate element 61 provided a limiting arrangement, which is just the adjustment of the intermediate element 61 limited. In the illustrated embodiment is on Transmission element 60 a sliding block 68 arranged in a backdrop 69th in the intermediate element 61 runs. For such a limitation are out of the state the technique known numerous other possibilities. Reference may be made to this become.

For the coupling between latch 1 and transmission element 60 is a very particularly advantageous embodiment. This is one by one Axis 70 pivotable driver 71 via a spring 72 to the transmission element 60 coupled. The latch 1 is in engagement with the driver 71 brought that during the adjustment of the latch 1 of the Vorrastin the closed position or in the main position of the catch 71 in Fig. 5th is pivoted to the right and thereby on the spring 72 an actuating force acts on the transmission element 60 in the second direction. In the result For example, the transmission element 60 is adjusted in the second direction. These Adjustment is, as already explained above, via the distance transmission means 11, in particular via the soul 11 'of the Bowden cable, to the control unit 7 forwarded. The coupling between latch 1 and driver 71 is achieved in that the driver 71 has a pin 73, the in the adjustment of the latch 1 in the closed position or in the main latching position detected by a hook-shaped shape 74 of the latch 1 and taken along accordingly. As a result, the spring 72 is tensioned and the transmission element 60 adjusted accordingly.

In a particularly preferred embodiment, the driver 71 has an additional Function, namely the intermediate element 61 in the pre-locking or in the open position located latch 1 (Fig. 4) to fix in a certain basic position. For this purpose, the intermediate element 61 has a formation 75, in which the driver 71 engages with the pin 73 in the above constellation. The limiting device 68, 69 then preferably exerts one of the fixing force of the driver 71 opposing force on the intermediate element 61, so that a stable equilibrium state arises overall. This ensures that that even if the latch 1 is not in direct contact with the intermediate element 61, the intermediate element 61 is still in a defined Position - basic position - is fixed.

For the adjustability of the transmission element 60 are a number of possibilities conceivable. In addition to the pivotability is in particular a longitudinal displacement especially advantageous, considering the direct coupling between the removal force transmission means 11, in particular between the Soul 11 'of the Bowden cable and the transmission element 60 taken into account. Around after each adjustment, a reset of the transmission element 60 in one Defined basic position, it is still in a preferred embodiment provided to provide a spring 76, which is connected to the transmission element 60 is coupled and just takes over this function.

It may be noted that the embodiment shown in FIGS. 4 and 5 can also be provided with a freewheel. Here you are allowed to the above statements are referenced.
