Definitions

  • the invention relates to a motor vehicle door lock, with a locking mechanism with a catch and pawl, and with a motor drive for a closing and opening aid device, wherein the closing and opening aid device has a rocker can be acted upon by the motor drive with the pawl mounted thereon.
  • a motor vehicle door lock of the design described above is in the context of DE 37 25 075 C1 described. There, the rocker is connected via a lever mechanism to the motor drive.
  • the well-known motor vehicle door lock has proven itself in principle, but is complex in its mechanical structure and encounters limits in particular, if, for example, a mechanical closing operation is to be initiated independently of the described motorized opening or closing, because the motor drive has failed.
  • the pawl is mounted on the rocker and has on its side facing away from a pawl pin on a control rod comprehensive pawl nose. Difficulties can in turn arise if, for example, a mechanical closing and / or opening movement should be carried out in case of failure of the motor drive.
  • the DE 101 14 065 A1 documents a Kraftchristturver gleich according to the preamble.
  • a rotary element as a rocker a driver, with the help of which the catch can take in the absence of, not activated or defective Zuziehzz the rotary member or the rocker in the main position. It is therefore already described a mechanical closing process.
  • the known teaching in addition to a Zuzleh Vietnamese for the rotary member or the rocker before a guide, which is in communication with a bolt on the respective rotary member.
  • the rotary element and the pawl is performed. Because this has a driving pin, which is guided in a guide slot.
  • the invention is based on the technical problem to further develop a generic motor vehicle door lock so that even in case of failure of the motor drive proper mechanical actuation of the locking mechanism can be initiated in a mechanical closing operation.
  • a generic motor vehicle door lock in the invention is characterized in that the motor drive has a toggle element acted upon by him with two toggle levers, which can transfer the rocker from a position "open”, with an entangled arrangement of the two toggle lever in a position "closed”, with an approximately extended course of the two toggle lever, and that the catch During a mechanical closing operation in the course of an overstroke movement, the rocker takes with it, so that the rocker is transferred from its position "open” to the position "closed”.
  • rocker arm It may be designed as a rocker arm and the other toggle lever as a drive lever one knee lever.
  • the rocker arm is connected to the drive arm of the rocker, while the motor drive operates on the drive lever.
  • the motor drive can also work on the rocker arm or on a pivot joint connecting the knee lever.
  • the rocker takes the catch in a mechanical closing operation, the rocker from its position “open” in the “closed” position.
  • a mechanical opening operation ensures that the rocker is transferred from its position "closed” in the “open” position. It is therefore important to ensure that a mechanical connection between the rotary latch and the rocker in a mechanical closing and optionally opening process, in the sense that the catch takes the rocker.
  • the rocker has this over a stroke stop for the catch, so that the catch moves in its overstroke position the rocker from its position "open” to the "closed” position when a mechanical closing operation is to be displayed. Conversely, of course, proceed in an opening process.
  • the described overstroke stop on the rocker ensures that the described mechanical connection between the rocker and the rotary latch is produced in a mechanical closing operation and optionally opening operation. This happens at a closing operation at least when the catch performs an overstroke. This means that in a mechanical closing operation when sweeping over its overtravel - and only then - does the rotary latch take the rocker from its "open" position to the "closed” position.
  • the invention is based on the recognition that the overstroke is usually not achieved when servo-closing, but the catch of the locking mechanism is incident in their main load and is pulled from there by means of the motor drive, so that an associated motor vehicle door flush with the vehicle body completes.
  • the overstroke is usually not achieved when servo-closing, but the catch of the locking mechanism is incident in their main load and is pulled from there by means of the motor drive, so that an associated motor vehicle door flush with the vehicle body completes.
  • it is necessary to mechanically transfer the rocker to the "closed” position and also to hold it here. This is ensured by the overheating stop already described.
  • the rocker Z-shaped with pawl arm and drive arm and central pivot point between the two aforementioned arms may be formed.
  • the overstroke stop may be arranged on a middle arm connecting the pawl arm and the drive arm. At this middle arm is also the fulcrum.
  • a motor vehicle door lock which initially allows a simple and functional servo closure. For this it is only necessary that the motor drive (with located in the main catch rotary latch), the rocker from its position “open” transferred to the "closed” position. This happens simply because the drive works with a drag lever, a cam, etc. on an element of the toggle element, so that both toggle lever take an approximately straight course.
  • a spring provided directly on the rocker may be realized in the form of a compression spring which urges the rocker "open” in the direction of its position, d. H. works contrary to the direction of force of the provided between the two toggle spring.
  • the force of the spring between the two toggle levers is dimensioned so that it exceeds the force of the compression spring on the rocker, so that the rocker regularly assumes the position "closed” when the power of the engine.
  • a motor vehicle door lock which has in its basic structure via a locking mechanism 1, 2 with rotary latch 1 and pawl 2.
  • the rotary latch 1 in its closed position surrounds a locking bolt 3, which is released in the open position of the rotary latch 1.
  • On the one hand corresponds to the closed position of an associated motor vehicle door and on the other hand its open position.
  • a motor drive 4, 5, 6 which has a merely indicated electric motor 4 and a drag lever 5.
  • any transmission element is conceivable instead of the drag lever 5 which is capable of applying a toggle element 6 with the aid of the electric motor 4 in such a way that it "interleaves" the two basic positions (cf. Fig. 1 to 3 ) and “stretched” (cf. Fig. 4 and 5 ) occupies.
  • the toggle lever element 6 has two toggle levers 6a, 6b.
  • the one toggle lever 6a is designed as a rocker arm 6a, while the other toggle lever 6b is a drive lever 6b.
  • the rocker arm 6a is connected via a rotary joint 7 to a rocker 8.
  • the drive lever 6b is coaxially connected via a further rotary joint 9 with the drag lever 5.
  • the drag lever 5 is at the transition from the Fig. 3 to Fig. 4 rotated with the aid of the electric motor 4 in a clockwise direction, so that a stopper 10 abuts on the drag lever 5 against the drive lever 6b and this also takes in a clockwise direction.
  • the two toggle levers 6a, 6b move to the extended position Fig. 4 transferred.
  • Another stop 12 on the drag lever 5 ensures that the rocker 8 from the “closed” position after the Fig. 4 . 5 can be transferred back to the "open” position by the electric motor 4 is applied counterclockwise and the drag lever 5 moves accordingly, so that the stop 12, the toggle lever element 6 from the housing fixed stop 11 and thus the entangled position after the Fig. 1 to 3 (again) is achieved.
  • the two toggle levers 6a, 6b are connected to each other via a pivot 13. Coaxially to this rotary joint 13 and its connecting axis 13 is a spring 14, which the two toggle levers 6a, 6b in the direction of their approximately elongated course and consequently the position "closed” the rocker 8 after the Fig. 4 and 5 applied. In the Fig. 1 to 3 one also recognizes that then the rocker 8 rests against the housing-fixed stop 11. As a result, take the two toggle lever 6a, 6b in their entangled position at a certain angle to each other, which is within the scope of the embodiment at about 60 ° to 70 °.
  • the spring 14 is a coil spring coaxially with the connecting axis 13 arranged turns and respective ends which rest on the one hand against a stop 15 on the drive lever 6b and on the other hand against a stop 16 on the rocker arm 6a.
  • another spring is provided, and although in the form of a compression spring which acts on the rocker 8, in its "open” position.
  • the spring 14 ensures in any case that when the force of the motor drive 4, 5, 6, the knee lever 6a, 6b take their approximately stretched course, so that the rocker 8 in the Position "closed” is transferred in total.
  • the motor drive 4, 5, 6 forms, including the toggle lever element 6 and in conjunction with the rocker 8 a closing and opening aid means 4, 5, 6, 8.
  • the electric motor 4 is capable of the locking mechanism. 1 , 2 in the contracted position Fig. 4 and can also ensure that the locking mechanism 1, 2 is opened again.
  • the drag lever 5 ensures with its stop 10 that the knee lifting element 6 passes from the entangled in the extended course, while the latter case corresponds to that of the further stop 12 on the drag lever 5 for the change of the extended course of the toggle element 6 out provides the entangled position.
  • This overstroke is in the Fig. 5 shown where it can be seen that only in the course of the overstroke (ie a rotational movement of the catch 1 beyond the main rest position) of the overtravel stop 18 comes against a stop surface 19 of the catch 1 to the plant. This has the consequence that in this overstroke movement and a related counterclockwise movement of the catch 1 and the rocker 8 is taken.
  • the rocker 8 and the catch 1 are coaxially mounted in the common pivot point 17.
  • the pawl 2 is mounted in a further pivot point 20.
  • the operation is in a mechanical closing operation as follows. In accordance with solid slamming the door of the locking pin 3 moves the catch 1 first about their pre-locking position after the Fig. 2 further into the main post position Fig. 3 ,
  • the rotary latch 1 moves counterclockwise about its axis of rotation or pivot point 17 and, following the main latching position, reaches the overstroke range as shown in FIG Fig. 5 is shown.
  • the overstroke stop 18 is taken on the rocker 8 of the catch 1, so that the rocker 8 from its position “open” to the Fig. 1 to 3 in the position "closed” according to the Fig. 4 and 5 is transferred.
