Definitions

  • the invention relates to a door lock, in particular a motor vehicle door lock, with a drive unit for a door lock element, wherein the drive unit has at least one drive motor and at least two winding elements acted upon by the latter for receiving (respective ends) of a drive means which can be wound on and unwound therefrom.
  • the door lock element is any element of a conventional door lock or motor vehicle door lock, for example an element of the locking mechanism, of the actuating lever chain or of the locking lever chain.
  • the door lock element in question is transferred from a first to a second functional position, for example, a locking element from the position "unlocked” in the position "locked”.
  • the drive unit can also ensure that the door lock element in question resumes its original position.
  • the door lock element automatically (for example, against spring force) returns to its original position when the drive unit is no longer working on the door lock element.
  • Such drive units are used in the generic state of the art according to DE 10 2006 011 083 A1 in order to improve the overall noise development.
  • the drive motor is connected to the door lock element in question via a traction mechanism arrangement.
  • the Switzerlandstoffanaku has two Anlagenstoffabitese, each of which is designed partly on a drive shaft of the drive motor and unwound.
  • the free end of the one Werstoffabitess with an engagement point with the door lock element is engaged and the free end of the other Werstoffabitess is also at another engagement point with the door lock element into engagement.
  • the structure is relatively complicated and malfunction can not be excluded in principle.
  • the invention is based on the technical problem of further developing a door lock of the embodiment described above in such a way that the required installation space for the drive unit is reduced again while the noise behavior is further improved, and at the same time a cost-effective and functionally reliable variant is made available.
  • a generic door lock in the invention is characterized in that between the two winding elements, a door lock element acting on deflection unit is run into the drive means.
  • the flexible drive means is therefore not directly - indirectly or directly - connected to the door lock element to be acted upon. Instead, the connection of the drive means with the door lock element in question takes place via the addressed deflection unit. As a result, a further significant improvement of the noise behavior is already achieved. Because the deflection unit connected to the door lock element is acoustically isolated (by the drive means) from the drive motor. In addition, a particularly compact construction is achieved because the deflection unit usually engages only at one connection point on the door lock element and not - as in the case of DE 10 2006 011 083 A1 - as it were two connection points are realized.
  • the two winding elements can have the same winding diameter. As a rule, however, different winding diameters are used. In this way, the two winding elements acted upon by the drive motor of different winding diameter together with the deflection unit inserted into the drive means form a differential cable. This differential cable is able to transmit greater forces to the door lock element, as the drive motor - without translation - would achieve.
  • the two winding elements can be designed according to the invention so that at the same time an increase in force of the force provided by the drive motor is present or observed at the deflection unit. This makes it possible to use drive motors of low drive power, for example, those in miniature form, which are small in size, require little power, and are designed cost-effectively.
  • the two winding elements may be formed as equiaxed winding drums.
  • the two winding elements or winding drums are usually arranged one behind the other directly on a shaft of the drive motor. This corresponds to a particularly compact and reliable design.
  • the two winding elements can also be designed as spaced-apart winding discs.
  • Winding elements are arranged regularly and not necessarily in a common winding plane. Preferably, they have two each Arranged perpendicular to this winding plane axes, which are advantageously arranged parallel to each other. In order to achieve a small size in this embodiment, it has proved to be advantageous if the two winding elements are placed in each case or together on a worm wheel acted upon by the drive motor. In the event that two worm wheels are realized, connected to the shaft of the drive motor drive worm between the two worm wheels dive and put them together in rotation.
  • the deflecting unit is advantageously a deflection disk wrapped around by the drive means.
  • This deflection pulley or the deflection unit in general can be connected directly to the door lock element.
  • an indirect connection of the deflection unit to the door lock element takes place, namely via an intermediate element.
  • any force transmission element can be used as the intermediate element, for example a rod, a cable or the like.
  • the flexible drive means may also be a rope, a chain, a belt, etc., which is guided over the two winding elements and the deflection and can be performed.
  • a door lock in particular a motor vehicle door lock, provided, which is initially characterized by special acoustic benefits.
  • a lock case such as drive motor and door lock element are connected to each other, and without that structure-borne noise can be transmitted at this point.
  • this is ensured by the flexible drive means and, on the other hand, by the deflection unit acted upon by the drive means.
  • a compact design is achieved, which manifests itself in the coaxial winding drums or the spaced-apart winding disks between which the common drive worm dips.
  • By the optional recourse to different winding diameter of the two winding elements a force transmission can be realized beyond.
  • relatively low-power and consequently small and inexpensive drive motors can be used, yet the functionality is guaranteed and also stiff door lock elements are securely transferred to their desired functional position.
  • main benefits are the main benefits.
  • FIG. 2 is a modified embodiment of FIG. 1,
  • Fig. 3 shows a further variant
  • a door lock in this case a motor vehicle door lock is shown.
  • This motor vehicle door lock may be located in a side door, tailgate, boot lid or the like of a motor vehicle and cooperates in a known manner with a lock holder on the associated body for the representation of a motor vehicle door lock.
  • the door lock has an indicated only in Fig. 1 lock case 1, in which a locking mechanism 2, 3 may be stored.
  • the locking mechanism 2, 3 is composed of a rotary latch 2 and a locking pawl 3 cooperating therewith.
  • the pawl 3 as a door lock element 3, on which a drive unit 4 to 9 operates.
  • the drive unit 4 to 9 is composed of a drive motor or electric motor 4 and at least two winding elements 6 that can be acted upon by the latter.
  • the winding elements 6, 7 serve for receiving (respective ends) of a drive means 8 which can be wound up and unwound thereon.
  • a drive means 8 which can be wound up and unwound thereon.
  • Fig. 8 is a representation, not limiting, of a rope, a belt or the like.
  • the ends of the flexible drive means 8 are respectively fixed to the associated winding element 6, 7 (see Fig. 1 to 3) or combined into a circle (see Fig. 4). It can be seen that the flexible drive means 8 is guided in a loop from one winding element 6 to the other winding element 7. In this loop or in the drive means 8 according to the invention a deflection unit 9 is running, between the two winding elements 6, 7.
  • the door lock element 3 to be acted upon is connected to the deflection unit 9. This can be done directly or indirectly via an intermediate element 10.
  • the intermediate element 10 may be a connecting rod or else a connecting cable, which is connected on the one hand to an axis of rotation 11 of the deflecting unit 9 designed as a deflecting disk 9 and on the other hand to a connecting point 12 of the lock element 3.
  • the two winding elements 6, 7 can have a same winding diameter Di and D 2 . However, the associated winding diameters Di and D 2 are advantageously designed differently. In this way, the two winding elements 6, 7 form a differential cable in conjunction with the deflection unit 9 that has run into the drive means 8. This differential cable may be arranged directly on a shaft 5 of the drive motor 4 (see Fig. 1).
  • the winding elements 6, 7 are each designed as coaxial winding drums. That is, both winding elements 6, 7 have the same axis of rotation, which coincides with the shaft 5 of the drive motor 4 in the context of the exemplary embodiment according to FIG. As a result, a particularly compact design is achieved.
  • the two winding disks are advantageous - but not necessarily - in one common winding plane, which coincides substantially with the plane of the drawing in Figs. 3 and 4. Perpendicular to this, the respective axes of the winding disks are arranged, which may be parallel to each other.
  • the shaft 5 of the drive motor 4 between the two winding elements 6, 7 dives.
  • the two winding elements 6, 7 are arranged in each case acted upon by the drive motor 4 worm wheels 13. Both worm wheels 13 are acted upon in accordance with the illustrations of FIGS.
  • the deflection unit 9 or the deflection plate 9 is looped around by the flexible drive means 8. If necessary, to tension the drive means 8, a tensioning device 15 shown only in FIG. 4 may be realized. In this case, the ends of the drive means 8 are not attached to the respective winding elements 6, 7, but the drive means 8 is guided as it were in a circle between on the one hand the tensioning device 15 and on the other hand the deflection unit 9. Of the circular drive means 8, the drive motor 4, its shaft 5 and the drive worm 14 are enclosed in this case.
  • the drive means 8 In order to move the drive means 8 back and forth and to generate the required actuating movements on the deflection unit 9, the drive means 8 is wound one or more times around the winding elements 6, 7.
  • the drive motor 4 For the drive of the winding elements 6, 7, the drive motor 4 in turn provides the drive worm 14, which meshes with associated and the winding elements 6, 7 supporting worm wheels 13.
