Definitions

  • the invention relates to an actuating device for a lock of a motor vehicle together with methods.
  • a door or flap of a motor vehicle basically comprises a lock of the aforementioned type.
  • the lock has a locking mechanism in order to be able to open and close a door or flap.
  • the locking mechanism basically comprises a rotary latch and a pawl for locking the catch in a latching position and optionally a blocking lever for blocking the pawl in its latching position.
  • the actuator is used to open the door or flap and therefore allows unlatching of the locking mechanism.
  • the actuator By pressing the actuator, the pawl from its detent position and, if necessary, the blocking lever of the blocking lever is moved out of its blocking position and the locking mechanism finally opened. Following this, the door or flap can be opened.
  • the actuating device usually has a release lever which is actuated in order to open or unlatch the locking mechanism.
  • a trigger lever is typically connected to a handle of the door or flap. It may be an external handle or an internal handle of the corresponding door or flap. If such a handle is actuated, the release lever is actuated or pivoted to unlatch the locking mechanism and thus to open the lock.
  • worm gear consisting of motor, worm and gear, used, since this a large gear ratio can be realized, so that on the one hand a very accurate control of the opening mechanism can be done while high release forces are available.
  • a power source for an electric lock may fail, for example, as a result of an accident.
  • a device should be available with which, however, an electric lock can be opened.
  • an actuating device for an electrical opening of a locking mechanism in which a first and a second current source are present.
  • the actuating device has an electronic control unit and a switch, which is controlled by the electronic control unit, in order to use it for electrical opening with sufficient power of the first power source and to use the second power source as an emergency power supply with insufficient power of the first power source.
  • the object is achieved by an actuating device having the features of the first claim.
  • Advantageous embodiments emerge from the subclaims.
  • the additional claim relates to a method for opening a Gesperres.
  • an actuating device for opening the locking mechanism comprises an electrical release mechanism with which a locking mechanism can be opened by actuating the actuating device.
  • the actuator can be actuated to open the locking mechanism.
  • the switch which is opened by applying a voltage and closes when the voltage drops or falls below a minimum voltage, comprises an electromagnet, which is able to hold the switch in the open position.
  • This switch is installed or installed in such a way that it is open in the presence of a power source intended for opening the lock, hereinafter also referred to as main power source or vehicle power supply.
  • the switch is installed and / or constructed so that it connects the actuator with an emergency power source, also called emergency power supply when the main power source.
  • an emergency power source also called emergency power supply when the main power source.
  • Disposal of this main power source also means that the voltage of the power source drops below a threshold at which an electrical opening using this power source is no longer possible.
  • Electrical release mechanism means that the actuator is operated by means of an electric drive in order to be able to open a corresponding locking mechanism.
  • Connecting the actuator to an emergency power source means that the emergency power source for a power consumer of the actuator is available such that when needed the consumer receives its required power from the emergency power source.
  • a switch comprises any form of switching means, and in particular also semiconductor switches and relays.
  • a main power source differs from an emergency power source in particular by a higher electrical power that can be provided by the main power source. Therefore, the main power source not only supplies power to the actuator, but also supplies a large variety of other components in a motor vehicle. In contrast, the emergency power source can be provided only for the power supply of the actuator.
  • the switch which is opened by applying a voltage and closes when the voltage drops or falls below a minimum voltage, comprises in one embodiment a spring, hereinafter also called contact spring, which is magnetically held in the open and biased position by means of the electromagnet. If the voltage drops or falls below a predetermined minimum value, the electromagnet is no longer able to hold the contact spring in the open position. The contact spring then jumps due to its bias in its closed position, whereby the switch is closed. This closing has the consequence that the emergency power source is available as an energy supplier for a power consumer of the actuator.
  • the aforementioned switch which is opened by applying a voltage and which closes when the voltage drops or falls below a minimum voltage, can alternatively or additionally open and close electrically or electronically controlled.
  • an electronic controller which monitors the voltage of the main power source and which uses a still available electric power when the voltage drops to close the switch so as to connect the actuator to the emergency power source.
  • the actuating device is preferably supplied directly with power by an emergency power supply or emergency power source if the switch which closes when an applied voltage drops or falls below a minimum voltage of a main power source is closed.
  • an emergency power supply or emergency power source if the switch which closes when an applied voltage drops or falls below a minimum voltage of a main power source is closed.
  • no control device or control device is required for such a closing, which controls the opening of a locking mechanism by receiving an electrical signal.
  • a lock can be opened by the emergency power supply even if not only the main power supply has failed, but also a control device of the actuator.
  • the actuating device comprises a control unit which controls an opening of the locking mechanism. If the actuating device is sufficiently supplied with power by a main power source, an actuation of the actuating device results in the control unit receiving a signal. The control unit then controls the opening of the locking mechanism.
  • a controller is associated with the advantage that positions of the lock can be monitored and depending on which opening can be controlled. For example, the case may occur that a locking mechanism can not be opened with the usual force and this is detected by the control unit by means of one or more sensors. The controller then activates an additional opening force to open the locking mechanism with increased force.
  • a preloaded spring may be present, which is released controlled if necessary by the control unit and thereby an additional force for opening a locking mechanism provided. It is therefore advantageous, inter alia, to be able to open a locking mechanism controlled by a control unit.
  • the actuating device comprises a switch, which is able to open electrically by pressing an associated locking mechanism by means of an emergency power supply. "Immediately" means that by closing the switch on an electric drive provided for this purpose, the voltage provided by the emergency power source is applied and thus an associated locking mechanism is opened. In particular, no signal is then forwarded to a control unit, which then controls an opening.
  • the actuating device comprises a switch, which transmits a signal to a control unit by actuation, the control unit, following receipt of the signal, controlling an opening of a locking mechanism by means of a main power source.
  • This switch is in particular at the same time the aforementioned switch, which is able to open electrically by pressing an associated locking mechanism by means of an emergency power supply.
  • the FIG. 1 shows an actuator and a locking mechanism, which can be opened by operating the actuator.
  • the locking mechanism comprises a rotary latch 1, which can be pivoted about its axis 2.
  • the rotary latch 1 is locked by a pawl 3.
  • By locking a lock holder 5 is held by the catch 1.
  • An associated door or flap is then closed.
  • the pawl 3 can be rotated counterclockwise around its axis 4 from the detent position, so as to open the locking mechanism.
  • the locked state is like in the FIG. 1 shown in the main locking position a locking surface 7 of the rotary latch 1 to a blocking surface 6 of the pawl 3 at.
  • the catch 1 has a further blocking surface 15 with which the catch can be locked in the pre-locking position.
  • the arm of the pawl 3 is angular.
  • the angled end 8 of the pawl 3 extends to a rotatably mounted pin 9 which is part of the actuator.
  • the bolt 9 can be rotated about an axis 10 around.
  • the bolt 9 is perpendicular from a gear 11 from.
  • a worm 12 abuts against the teeth of the gear 11.
  • the worm 12 is connected to a shaft 13 of an electric motor 14.
  • FIG. 2 shows a vehicle power supply 16 and an emergency power supply 17. Both power supplies are connected to an actuating switch 18, which is actuated for an electrical opening of the locking mechanism.
  • a control device for the actuator together with locking mechanism comprises two switches 19 and 20. If the operating switch 18 is actuated, a signal is forwarded to the control unit. The controller then closes the switch 20. This has the consequence that the actuator is supplied with power and the electric motor 14 electrically opens the locking mechanism.
  • the switch 19 is held in this time by an electromagnet 21 in the open position.
  • the electromagnet 21 draws its required power from the main power source, so the vehicle power supply 16. If this power supply for the solenoid 21, so that moves in the open state biased contact spring 22 of the switch 19 in the closed position due to their spring force.
  • the electromagnet 21 is no longer supplied with sufficient power or no longer with power. Thereafter, the switch 19 closes. If now the actuation switch 18 is actuated for an electrical opening, then current is forwarded from the emergency power source 17 via the electrical switch 19 directly to the actuating device. The actuator opens and that even if the controller with the switches 19 and 20 also fails.
  • the emergency power source 17 is in particular part of the actuating device.
  • the actuating device is designed as a module which comprises the emergency power source 17 and which is installed as a module in a vehicle door or a vehicle door. In the non-installed state, the actuating device thus already includes the emergency power source 17. This is especially possible because the emergency power source may be a sufficiently small sized battery. This embodiment ensures improved that an electric lock can be opened even if a main power source 16.
