Definitions

  • the invention relates to a locking system for a motor vehicle with a locking mechanism, which can be opened electrically.
  • a locking mechanism comprises a rotatably mounted rotary latch for receiving a locking bolt.
  • the locking mechanism further has a pawl with which the catch can be locked.
  • the consisting of metal and / or plastic parts of the locking mechanism are usually mounted rotatably on a metal plate consisting basically of metal.
  • Such a lock is known from document WO 2015/172761 A1.
  • the catch of a motor vehicle locking system usually has a bifurcated inlet slot formed by load arm and catching arm into which the locking bolt of a vehicle door or flap, for example bonnet or trunk lid, comes when the door or flap is closed. The locking pin then rotates the catch from an open position to a closed position.
  • the catch If the catch has reached the closed position, it is locked in this position via the pawl.
  • the locking pin can then no longer leave the inlet slot of the rotary latch.
  • In the locking position is a locking surface, also called blocking surface, the rotary latch pressed against a locking surface of the pawl.
  • the pawl is therefore exposed in its rest position to a contact pressure. This contact pressure must be overcome in order to move the pawl out of its detent position.
  • the actuator may be an external actuator or an internal actuator that is pivoted for actuation, for example.
  • An external actuating element may be an outside door handle of a motor vehicle, which thus makes it possible to open a vehicle door from the outside, for example by pivoting. The same applies to an outside handle of a flap.
  • An external actuator may be a button.
  • An internal operating element can be reached from the interior of a motor vehicle. It can be a pivotable handle or act on a button.
  • An actuator may be a mobile remote control, which is not connected to the motor vehicle and which is capable of transmitting an opening signal wirelessly by operation.
  • An actuation of an actuating element is mechanically transmitted, for example mechanically via a linkage or a Bowden cable to a release lever.
  • an electrical signal can be transmitted to a drive, so that opening takes place with the aid of the drive.
  • a wireless signal transmission to a drive is possible. If the release lever is pivoted in this way, the pawl is indirectly or directly moved out of its rest position and the locking mechanism opens.
  • a lock of the type mentioned above can be locked beyond.
  • the chain of action is interrupted by an actuating element so that actuation of the actuating element does not result in opening of the locking mechanism.
  • the claimed locking system includes a locking mechanism with a catch and pawl for locking the catch in a latching position. In order to open the locking mechanism with little effort, there is an electric drive, with which the pawl can be moved out of its rest position, so as to open the locking mechanism. There is a locking device for locking the locking system.

  • the unlocked state it is possible to open the locking mechanism and that electrically or mechanically. By pressing the external actuating element, such a locking system and thus the locking mechanism can not be opened in the locked state. If the locking system is not locked, it can be opened by pressing the external actuating element, the locking system and thus the locking mechanism.
  • An external actuating element in the context of the invention is intended and suitable for being permanently attached to a motor vehicle from outside.
  • the external actuating element can therefore be actuated from the outside.
  • An external actuator is designed to withstand external climatic conditions.
  • the external actuating element can be moved along a short path, thereby opening the locking mechanism with the aid of the electric drive. If the locking system is unlocked so that it can be mechanically opened by operating an external actuating element, the external actuating element can be moved along a long path, thereby opening the locking mechanism by manual force, without having to use electrical energy.
  • the long way is longer than the short way.
  • a way in the sense of the invention can be covered by a lifting movement and / or pivoting movement.
  • the locking system includes a locking device that allows movement of the external actuating element along the long path only when the locking system is unlocked so that it can be mechanically opened. If the locking system is unlocked so that, although it can be electrically opened, but not mechanically, so the outer actuator can be moved only along the short path. If the end of the short path is reached, the blocking device then blocks further movement of the external actuating element. But has been unlocked so that can be opened mechanically, so the outer actuator can be moved beyond the end of the short path out until the end of the long path.
  • the short way is basically one Part of the long way. Both ways basically have the same starting point.
  • the blocking device is not part of the external actuating element. Instead, the blocking device is arranged in the vicinity of the release lever and removed from the outer actuator. The distance between the blocking device and the trigger lever is therefore small compared to the distance between the blocking device and the external actuating element. This arrangement makes it possible to provide the blocking device with little technical effort. In particular, the distance between the blocking device and the release lever is less than 10 cm in order to avoid an unnecessarily large installation space.
  • the external actuating element is basically connected via a Bowden cable or a linkage with the blocking device. Movement of the outer actuating element along the short or long path is transmitted to the blocking device by the Bowden cable or the linkage. If the locking device is not unlocked so that it can be opened mechanically, the blocking device blocks further movement of the outer actuating element when the end of the first short path has been reached. If the locking device is unlocked so that it can be opened mechanically, the blocking device does not block further movement of the external actuating element when the end of the short path has been reached. The external actuator may then be moved to the end of the second long path.

Abstract

Un but de l'invention est de proposer un système de fermeture d'une porte ou d'un hayon d'un véhicule automobile. La porte ou le hayon peut être ouvert rapidement et aisément. Le système de fermeture de l'invention comporte un mécanisme d'encliquetage à pêne tournant et à cliquet d'arrêt pour bloquer le pêne tournant dans une position d'encliquetage. Pour pouvoir ouvrir le mécanisme d'encliquetage avec peu d'effort, il est prévu un entraînement électrique au moyen duquel le cliquet d'arrêt peut être déplacé hors de sa position d'encliquetage de manière à ouvrir le mécanisme d'encliquetage. Un dispositif de verrouillage est prévu pour verrouiller le système de fermeture. Si le système de fermeture est déverrouillé de sorte que le mécanisme d'encliquetage peut être ouvert électriquement par actionnement d'un élément d'actionnement extérieur, l'élément d'actionnement extérieur peut alors être déplacé sur un court trajet pour ouvrir ainsi le mécanisme d'encliquetage à l'aide de l'entraînement électrique. Si le système de fermeture est déverrouillé de sorte que le mécanisme d'encliquetage peut être ouvert mécaniquement par actionnement d'un élément d'actionnement extérieur, l'élément d'actionnement extérieur peut être déplacé sur un long trajet pour ouvrir ainsi le mécanisme d'encliquetage par une force manuelle sans avoir à utiliser d'énergie électrique. Le long chemin est plus long que le court chemin. Le système de fermeture comprend un moyen de blocage qui permet de déplacer l'élément d'actionnement extérieur sur le long trajet uniquement lorsque le système de fermeture est déverrouillé de manière à pouvoir être ouvert mécaniquement.
