Definitions
- the invention relates to a motor vehicle door lock, with a rotary latch, a pawl, and with one Drive, with the interposition of an eccentric directly or indirectly on the pawl to open the catch works.
- a trigger lever interposed be what corresponds to that the eccentric indirectly on the pawl to open the catch is working.
- the pawl grips an arm by way of example the pawl to open the catch.
- eccentric means a component which over an eccentric contour, for example one Cam, features to lock the pawl within one certain adjustment range so that the Catch (spring-assisted) can open.
- the drive usually takes place, but not in a restrictive manner, using an electric motor.
- a motor vehicle door lock of the type described above Design is exemplified in the two published documents DE 101 40 957 A1 and DE 196 50 826 A1 are described.
- the drive in the present application will be like this used for the so-called electrical opening or Unlocking the associated motor vehicle door lock display. This may be initiated, for example, that an operator willing to access has an outside door handle actuated.
- a switch provided here then starts with With the help of a control device the drive. in principle can this start process also in connection with a "Keyless entry" access is triggered by a remote query between a means of identification of the Operator and the associated motor vehicle. Either way is the electric motor from the control device in the Senses that the eccentric on the pawl - if necessary with the interposition of further levers - for Opening the catch works.
- the invention is based on the technical problem Motor vehicle door lock of the configuration described in the introduction to develop so that safe digging the pawl succeeds, especially without the pre-hooking previously described.
- the blocking means provided according to the invention thus ensures for the eccentric in the raised position of the Pawl is held. This will raise the Position of the pawl frozen as it were. This Condition lasts until the opening catch separates the blocking agent from the eccentric. This can be done by an electric motor happen by a querying the rotary latch opening and anyway existing sensor a motor or a otherwise such a device so that the Blocking agent is lifted from the eccentric.
- the eccentric is therefore free, so that the pawl (spring-assisted) return to their starting position can.
- the eccentric which also spring-assisted or motorized in the starting position is moved back.
- the rotating catch makes mechanical contact with the blocking agent to remove the blocking agent from Separate eccentric.
- the rotary latch has via a lifting tooth, which the blocking agent from Eccentric separates.
- the eccentric is constructed in two parts is and has a cam wheel and a drive wheel.
- the cam wheel and drive wheel may each coaxial Compared to a common axis.
- the Drive wheel is connected to the drive while the Cam gear works on the pawl.
- the eccentric may have a spring that follows it Removal of his blockage by the blocking agent in his Starting position transferred.
- this feather arranged between the drive wheel and cam wheel and is excited as soon as a cam of the cam wheel on the pawl or an intermediate lever at the beginning the lifting movement of the pawl comes to rest.
- the Spring is now increasing due to the ongoing drive excited because the cam on the pawl or the intermediate Lever is set. This process will continued until a mechanical entrainment of the Cam wheel is reached by the drive wheel and consequently the pawl is lifted.
- the Tension of the spring is released during the entire blockade of the Maintain eccentric. Only when the blocking agent on the part of the opening catch from the eccentric has been separated, the spring can relax and ensures that the cam wheel and consequently the eccentric as a whole returns to its starting position. It will explained in more detail with reference to the figure description become.
- the blocking agent is a two-armed one Lever with blocking lever arm and operating lever arm.
- the Blocking lever arm or the blocking agent as a whole is able to fall into a recess of the eccentric. This recess of the eccentric is found regularly on the cam wheel.
- the operating lever arm acted upon by the opening catch to the Disconnect the blocking agent or the blocking lever from the eccentric.
- the lifting tooth ensures this - as described the catch.
- the Lever or blocking lever coaxial to the pawl.
- the invention proposes that the drive so long in the raised position of the pawl until a sensor detects the opening movement of the catch finds. That is, at the time when that Blocking means or the blocking lever on the part of the catch the drive is located from the eccentric in peace.
- This process can be an undesirable Exclude reverse rotation of the drive wheel because the spring force is low and the self-locking forces of the Drive cannot overcome.
- the cam gear is consequently when it reaches its starting position by the the spring in question is braked, without that on one hard mechanical stop must be used. This is of course accompanied by noise reduction instead of.
- Blocking agent ensures that the pawl is held in the raised position, and so long until the opening catch catches the blocking agent separates from the eccentric. This can cause the previously problematic Snapping hooks can be avoided properly because the catch only then separates the blocking agent from the eccentric, if they swept a certain predetermined opening angle has or has clearly passed through the pre-locking position Has. At the same time, the pawl engages securely guaranteed when closing the catch, d. H. so-called false closings do not take place.
- the blocking position of the drive can be simple and be determined at short notice, so that with a electromotive design only a short current until the drive is switched off.
- the main features can be seen here.
- FIG. 1 shows the motor vehicle door lock a catch 1 with a main catch 2 and a Vorrast 3 is equipped. With this catch 1 acts a pawl 4 together in the usual way. In addition, a drive 5 is realized, which for the Lifting the pawl 4 and consequently opening the Catch 1 ensures.
- the drive 5 operates within the scope of the exemplary embodiment with the interposition of an eccentric 6 immediately on the pawl 4 to open the catch 1. Basically in addition to the eccentric 6 could also leverage, for example a release lever, interposed. Then would the eccentric 6 indirectly on the pawl 4 Act on opening of rotary latch 1. However, that is not shown.
- eccentric 6 as an eccentric disc Cam 10 is executed by a worm wheel 5b is driven, which in turn is powered by an electric motor 5a is rotated.
- Electric motor 5a and Worm wheel 5b form the electromotive drive 5, in the context of the embodiment in only one direction works on the eccentric 6 in question, namely, that the eccentric 6 only those in the figures indicated counterclockwise movements performed.
- a blocking means 7 in the form of a can also be seen two-armed locking lever 7.
- the locking lever 7 and the Pawl 4 are arranged coaxially to each other, rotate So around the common axis 8.
- the two-armed Blocking lever 7 has a blocking lever arm 7a and an operating lever arm 7b, on both sides of the axis 8th.
- the pawl 4 is equipped with a molded extension 9, which acts on the cam 10 of the eccentric 6 becomes. As soon as this cam 10 against the boom 9 strikes, the pawl 4 by a counterclockwise rotation excavated around axis 8, as is the case with Detects transition from FIG. 2 to FIG. 3a, so that the Rotary trap 1 is released and spring-supported for their Axis 11 can turn clockwise. That will be in detail are explained in more detail below.
- the eccentric 6 is constructed in two parts and has a cam gear 6a and a drive gear 6b.
- the drive wheel 6b meshes with the drive screw 5b and is thereby in Counterclockwise rotations offset.
- common axis 12 is arranged between the Cam wheel 6a with the cam 10 thereon and the Drive wheel 6b, both coaxial compared to one are arranged common axis 12 .
- the spring 13 works both clockwise and also counterclockwise, d. H. can be in the two compress and relax the aforementioned directions.
- Fig. 1 shows the starting position of the motor vehicle door lock with in the Main pawl 2 pawl 4. Between the cams 10 of the eccentric 6 and the boom 9 of the pawl 4th there is no interaction. The spring 13 is not under tension.
- Pawl 4 moves the electric motor 5a to block as soon as the blocking lever 7 has fallen into the recess 14. Because a spring is not expressly shown for that the blocking lever 7 in the direction of this required clockwise rotation about its axis 8 biased is.
- the electric motor 5a is in this blocked position continue to be energized until one of the catch 1 assigned and not shown sensor between the The main catch 2 and the catch 3 recognize that the catch 1 makes an opening movement. This condition is roughly reached in the context of FIGS. 3a, 3b.
- the pawl 4 is throughout this Functional processes in their raised position. This The position is frozen, as it were, because the cam 10 works unchanged on the boom 9 and this position because of the definition of the cam wheel 6a with the help of Blocking lever 7 does not leave. As soon as the catch 1 in their spring-assisted opening process, d. H. of their Clockwise rotation around axis 11, the pre-locking position has gone through, she starts using her lifting tooth 15 to work on the blocking lever 7.
- the Blocking lever 7 performs one in this process 3b indicated clockwise movement or will be as shown after the front view in Fig. 3a or according to Fig. 4 counterclockwise moves, as indicated by corresponding arrows. Thereby the blocking lever arm 7a pivots out of the recess 14 out.
- the opening catch 1 thus separates the blocking agent or the blocking lever 7 from the eccentric 6, namely, when the latch 3 of the catch 1 on a retaining lug 18 of the pawl 4 moves past during its opening process Has. That is, the lifting tooth 15 is in one Position on the rotary latch 1, which ensures that the Holding lug 18 on the pawl 4 no (more) with one the locking positions, either pre-locking 3 or main locking 2, can cooperate with spring support. That at the beginning described advance hooks can therefore be based on the reason no longer occur.
- the blocking lever remains as long as the rotary latch 1 is open 7 also completely excavated, because the Lifting tooth 15 the actuating lever arm 7b of the blocking lever 7 applied accordingly. Because the cam 10 the boom 9 the pawl 4 has released completely, can the pawl 4 - supported by a not shown Spring - place on the rotary latch 1. Because that relevant spring acts on the pawl 4 clockwise.
- the pawl is 4 consequently able to close the catch 1 (counterclockwise rotation by a grasped Locking bolt) either in the preliminary catch 3 or the main catch 2 can come up with.
- the closing movement of the rotary latch 1 now has the result that the lifting tooth 15 the blocking lever arm 7b of the blocking lever 7 leaves, so that the Locking lever 7 is spring-loaded on the contour 17.
- the starting position shown in FIG. 1 is thus again reached.
