Definitions

  • the invention relates to a door lock according to the preamble of claim 1.
  • the transmitter also called a radio key
  • the transmitter generally delivers a signal that is transmitted wirelessly to the control electronics via the signal receiver and works, for example, on the basis of electromagnetic waves.
  • the actuator can then, when the control electronics receive a corresponding signal from an associated radio key, open the door lock or move it into a pre-locking position, from which the door lock can then be opened, for example, with the help of the usual door handle.
  • Such door locks are very user-friendly. However, they usually have a particular disadvantage. Their mode of operation depends on the functionality of the vehicle electrical system, from which the actuator or the control electronics are supplied with energy. In the event of an accident or a fault in the vehicle electrical system, however, a condition can arise in which the proper functioning of the control electronics or the actuator is no longer possible is guaranteed.
  • the invention has for its object to provide a door lock of the type mentioned, which maintains the advantages mentioned with little additional effort and which is also functional in case of need or emergency.
  • the features of claim 3 show a simple way to activate the energy storage when necessary.
  • the particular advantage is that the failure of the vehicle electrical system is not particularly unpleasant for the user and the activation of the energy storage for the vehicle user takes place in a natural and practical "natural" manner.
  • the vehicle electrical system is not able to operate the actuator, the vehicle user can usually recognize the faulty process. He will then try to open the door in the usual way using the door handle. This activates the energy storage.
  • the door lock can then be opened by the vehicle user. For example, he can trigger an opening signal again using the radio key and thus use the signal receiver to move the actuator in the opening direction.
  • it is also possible to mechanically open the door lock if a mechanical connection between the door handle and the door lock is provided via the actuator activated by the signal receiver and the energy store.
  • a supplement or alternative to a self-sufficient energy storage is the subject of claims 4 and 5.
  • an energy generator is provided which can be moved with the help of the door handle, for example in the manner of a dynamo.
  • the energy generator can only be activated if necessary.
  • a door lock is shown schematically, which can be opened electrically even if the vehicle electrical system fails.
  • a door lock of a motor vehicle is shown schematically as a rotary latch 2 and locking lever 3.
  • a nose 4 of the locking lever 3 engages behind a projection 5 of the rotary latch 2.
  • an actuator 6 that can be moved by an electric motor is provided, which acts on a cantilever 7 of the locking lever. This is possibly moved in a direction indicated by an arrow 8 in the figure.
  • the nose 4 comes out of engagement with the projection 5.
  • the door not shown in detail, can be opened.
  • the actuator 6 is normally controlled by control electronics 9, which is also arranged in the door, for example, and which cooperates with a signal receiver 10.
  • the signal receiver 10 receives wirelessly transmitted code signals which are transmitted by a radio key 11 shown schematically. If the signal receiver receives a code signal of the associated radio key, the control electronics 9 are activated and the actuator 6 is moved in the direction of arrow 8. Instead of a code signal transmitted by the radio key, the control electronics 9 can also be activated automatically in the event of a serious accident with the aid of a crash switch 12 and the actuator 6 can be actuated.
  • the sequence described is effective as long as the electrical system of the motor vehicle is intact, that is to say it provides an adequate energy supply for the control electronics 9 and the actuator 6.
  • the electrical system is supplied with energy by a schematically illustrated electrical system battery 13. If their connection to the control electronics 9 is interrupted or the connection between the signal receiver 10 and the control electronics 9 is interrupted or the on-board electrical system battery 13 is discharged, the actuator 6 can no longer be supplied with energy from the on-board electrical system battery.
  • a separate energy store 14 is provided, which is integrated, for example, with the signal receiver 10.
  • the energy store 14 can be connected to the signal receiver 10 by a switch 15.
  • This case occurs automatically, for example, when a threshold switch provided in the signal receiver 10 detects an interruption in the energy supply by the on-board electrical system battery 13 or a drop below a predetermined on-board electrical system voltage value.
  • switch 15 it is possible to switch 15 in this case with a not shown in detail to couple the door handle and only manually connect the energy store 14 to the signal receiver 10 when they are actuated.
  • the energy store 14 is connected to the signal receiver 10.
  • the signal receiver 10 then works independently and, if necessary, enables the actuator to be controlled independently of the control electronics 9 and the door lock 1 to be opened.

Claims (6)

  1. Serrure de portière (1) pour véhicule automobile, comprenant un organe de réglage (6) entraîné par un moteur électrique et commandé par une électronique de commande,et en fonction d'un signal de commande émis par un émetteur, cet organe se mettant dans une position préparant l'ouverture de la portière,

    caractérisée en ce que
    l'accumulateur d'énergie se charge par un générateur d'énergie couplé à la poignée de portière.
  5. Serrure de portière selon la revendication 4,
    caractérisée en ce que
    la poignée ne se règle dans un mode de génération d'énergie qu'en cas de nécessité seulement.
  6. Serrure de portière selon l'une quelconque des revendications 1 à 5,
    caractérisée en ce que
    l'accumulateur d'énergie alimente le cas échéant également l'organe de réglage d'une autre serrure de portière.
