Definitions

  • the invention relates to a motor vehicle door lock or the like. With the features the preamble of claim 1.
  • Motor vehicle door locks or the like of the type in question are door locks for side doors, for rear doors, for tailgates etc. on motor vehicles. Therefore, in the following, the more general term motor vehicle lock is always used used. These motor vehicle locks are usually available with a lock latch and pawl, but in some versions also with a single, direct interact with the striker on the counterpart of the body Latch. Therefore for the present description the general Term jack used to cover both variants.
  • the electronic control of the motor vehicle lock must of course recognize when the direction of rotation of the electric drive motor is reversed must become. This can be the case, for example, if after a specified time after the opening command has been triggered, the jack is not lifted has been detected when a too high actuating force is detected (the electrical Drive motor draws higher current than allowed, the speed of the electric Drive motor falls off) if via a known crash sensor an accident situation has been detected when due to voltage drop performance on the vehicle electrical system or due to special environmental conditions of the electric drive motor is too low when on an emergency power supply has been switched.
  • the known motor vehicle lock already realizes the advantage of short positioning times, which in particular in connection with systems for "passive entry" are important.
  • Another significant advantage is that the electric drive motor can be designed for normal operation, the reduction gear modified accordingly for emergency operation becomes. So it can be an electric drive motor of relatively low power be used. This allows a small and inexpensive electric motor be used. That has another positive effect for one possibly existing emergency energy supply, which then also only the underperforming must drive electric drive motor, which over the larger reduction ratio of the reduction gear in emergency operation works at the expense of the operating times.
  • the reduction gear is a combination of Worm gears and cam gears realized, being in cam gears
  • Different lever arms of the operating lever for normal operation and emergency operation will be realized.
  • This conception leads to a comparative space-consuming construction. That is why it is already in the state of the art proposed to implement a gear transmission with two gear stages, the second gear stage then being activated in emergency operation is switched off in normal operation, for example via a freewheel is.
  • switching between is also possible for the two gear stages two gear stages when the gear stage that is not used is running. intended.
  • This construction with two gear stages too and gear transmission is comparatively space-consuming.
  • a planetary gear significantly with a given reduction ratio more compact than any other form of gear. For example, one can achieve a reduction ratio of 6: 1 with a size in which a Gear transmission would only reach approx. 2: 1 as a reduction ratio.
  • a planetary gear is just for a symmetrical structure of the motor vehicle lock of great importance because it is level with the Arrangement of ring gear, planet carrier with planet gears and sun gear is built in a way "disk-like" and by both Flat sides as can be coupled from the circumference.
  • a lock latch 1 designed as a rotary latch is shown schematically shown, which is mounted on an axis 2 on the housing, not shown is. Furthermore, the lock latch 1 is in the closed position with the main catch and Locking pawl 3 is provided which latches on a pawl axis 4 is stored.
  • This is supposed to give a basic understanding of the structure of the motor vehicle lock serve as explained as a side door lock, rear door lock, Tailgate lock etc. can be used.
  • lock latch 1 and pawl 3
  • pawl 3 The combination of lock latch 1 and pawl 3 is shown. Thanks it has been explained above that one can also work with an integrated latch could that directly with the striker on the opposite body part comes into engagement. Such constructions are also occasional still in use.
  • the electric drive motor 5 is a reduction gear downstream, with which the high speed of the electric Drive motor 5 reduced to a much lower drive speed becomes.
  • One is driven by the reduction gear with the pawl 3 coupled actuating lever 7. In the exemplary embodiment shown this coupling by means of the recognizable square pin.
  • the position of the actuating lever shown in solid lines in FIG. 1 7 denotes the position with the latch 3, which is shown in broken lines Location, with the jack raised 3. Without further ado, the operating lever 7 remain in the position with the jack 3 raised, provided that Pawl 3 in the open position of the latch latch 1 Position would be held. That is in itself with the construction shown also unproblematic. However, an additional measure is provided here namely in the form of a rocker arm 9 assigned to the pawl 3. With this, the actuating lever 7 can already return to its rest position, even if the pawl 3 still remains in the raised position. The is achieved in that the actuating lever 7 on the square pin 8th firmly coupled with the rocker arm, with pawl 3 only via the rocker arm 9 coupled entraining in one direction, otherwise against spring force deflectably connected.
  • the normal actuator 10 is in the illustrated embodiment designed as a stepped cam that starts on the actuating lever 7.
  • Fig. 4 shows the emergency actuator 11, which also with the Actuating lever 7 cooperates and in the Ausshmngsbeispiel shown is also designed as a cam.
  • Fig. 4 shows the rest position the emergency operating element 11 in solid lines, the lifting position in dash-dotted lines.
  • Fig. 1 could give the impression that the reduction gear a combination in a manner known per se from the prior art from worm gear and cam gear
  • Fig. 2 and Fig. 3 that the reduction gear further includes a planetary gear with sun gear 12, planet gears 13, summarized in 2 schematically indicated planet gear carrier 14 and ring gear 15.
  • Fig. 3 shows a corresponding section.
  • the use of a planetary gear at this point has considerable space advantages and is drive technology and very inexpensive.
  • the illustrated and preferred embodiment now shows that the reduction gear as a combination of worm gear, Planetary gear and cam gear is executed.
  • the worm gear shows the worm 16 and the worm wheel 17, the planetary gear shows the previously explained components and the cam mechanism is through the Actuators 10, 11 on the one hand and the actuating lever 7 on the other formed, being a normal cam gear or an emergency cam gear takes effect, depending on the direction of rotation of the drive motor 5.
  • the illustrated embodiment is further characterized by that the normal actuator 10 and the emergency actuator 11 arranged on opposite sides of the planetary gear are. This can be seen particularly well in FIG. 3. This is an optimal one Housing on the two flat sides of the planetary gear realized, a particular advantage of the compact planetary gear optimally used.
  • the outer circumference of the planetary gear is used by the worm wheel 17 to attack the electric drive motor 5, the Depending on the operating mode, power is transferred to jack 3 from one or other flat side of the planetary gear.
  • the illustrated and in this respect preferred embodiment also shows that the operating lever 7 in emergency operation from the emergency actuator 11 is immediately moved that a normal operating lever on the operating lever 7 7 'is pivotally mounted that the normal operating lever 7 'abuts against a stop 20 and from there in one direction can be deflected against spring force and that in normal operation the normal operating lever 7 'and rigidly coupled above the actuating lever 7 is moved by the normal actuator 10.
  • the electric drive motor 5 starts up, the worm gear 16 rotates the worm wheel 17, which is steppedly attached to the worm wheel 17 Cam, which forms the normal actuator 10 is counterclockwise, in Fig. 1 in the direction of the arrow, rotated. This rotation takes place at high rotational speed because there is no additional reduction except that the worm gear is effective.
  • the normal actuator 10 hits the normal operating lever 7 'on the operating lever 7 is mounted and abuts the stop 20. Therefore from Normal operating lever 7 'of the operating lever 7 immediately in the in Fig. 1st Lift position shown in dash-dotted lines.
  • the jack 3 is has been moved to the raised position.
  • the emergency operating element is also in normal operation during the entire function 11, in the illustrated embodiment with the planet carrier 14 is rigidly coupled, has been moved. This movement takes place counterclockwise in Fig. 4. However, this movement has no function stayed because the movement of the normal actuator 10 in Fig. 1 around the reduction ratio of the planetary gear faster and so that it was carried out with considerable lead time.
  • the electric drive motor 5 is used in its Reversed direction of rotation. That means that from the solid Lines shown position in Fig. 1, the normal actuator 10 in Rotates clockwise. With the same direction of rotation, but around the reduction ratio of the planetary gear reduced rotational speed the emergency actuator 11 also moves clockwise in FIG. 4. It hits directly in accordance with the curve shape of the cam on the operating lever 7, which is yes in the level of the emergency operating element 11, is not in the plane of the normal actuating element 10.
  • the illustrated The embodiment has a higher reduction ratio not only in the planetary gear for emergency operation, but also here in cam gear between the emergency actuator 11 (cam) and the longer operating lever 7.
  • the emergency actuating element is placed in the exemplary embodiment shown 11 (cam) an angle of rotation of approximately 230 ° back from the rest position to the lifting position shown in broken lines. Due to the reduction ratio realized in the planetary gear meanwhile places the normal actuating element, which is designed as a stepped cam 10 a movement over a much larger one Angle of rotation back.
  • the normal actuating element 10 passes through the Normal operating lever 7 ', that is shown in Fig. 5. Because the normal operating lever 7 'but against the operating lever 7 in this direction Spring force is deflectable, it is easy from the normal actuator 10 deflected to the side without the lifting movement of the operating lever 7 to hinder in emergency operation.
