Definitions

  • the invention relates to a lock for a vehicle door according to the preamble of patent claim 1.
  • Locks for vehicle doors are known in numerous variations. These locks comprise at least one opening mechanism which can be coupled to a first drive, a clutch which can be mechanically converted into a force-transmitting state by at least one manual actuating element and which couples the at least one opening mechanism to the first drive in the force-transmitting state, a second drive coupled to a securing element, wherein the securing element blocks an inner actuating element in a first stationary position, and an evaluation and control unit which outputs corresponding control signals to the first drive and the second drive.
  • a locking device for a lock of a vehicle door which comprises a means of an external locking element also remotely activated lockable position.
  • an influence of external actuation elements and / or internal actuation elements and inner securing elements is prevented on the locking position by force flow interruption on disengageable couplings.
  • a lock for a vehicle door which has a closing device for fixing the vehicle door in the closed position and a Verrieglungs adopted for locking the vehicle door in the closed position.
  • the closing device comprises a movable actuating element for introducing a force into the closing device for removing the fixation of the vehicle door.
  • the locking device comprises a movable locking element which prevents actuation of the closing device in a predetermined position and thus locks the attachment in the closed position.
  • the lock has a power transmission device, by means of which the force from the actuating element to the locking element for the purpose of movement of the locking element is transferable, wherein the power transmission device is configured such that a force from the actuating element to the locking element for the purpose of movement of the locking element for realizing a locking of the vehicle door is transferable.
  • the object of the invention is to provide a simple lock for a vehicle door, which allows an electrical opening of the vehicle door via a manual operation of a remote control and / or an actuating element on the vehicle, the safety of the occupants is not endangered, especially in an accident situation.
  • the coupling couples in a force-transmitting state at least one opening mechanism with a first drive.
  • the first drive generates at least a first driving force, which is transmitted from the clutch in the force-transmitting state to the opening mechanism.
  • the opening mechanism opens the vehicle door due to the driving force.
  • Such a coupling is known in an advantageous manner from the prior art and can be mechanically inserted by at least one manually actuating element.
  • the second drive is already known from the prior art and drives the securing element.
  • the securing element acts as theft protection and locks an internal operating element in a first stationary position.
  • the second drive can be activated via a manual actuation of an actuating element, whereby the coupling can be converted into the force-transmitting state via a force transmission element, which is driven by the second drive via the securing element.
  • the vehicle door can not be opened in case of a false signal because the clutch must be inserted first. Since different drives are responsible for opening the vehicle door and engaging the clutch, the risk of accidental opening can be advantageously reduced.
  • components, in particular a further drive can advantageously be saved, since with the exception of the force transmission element already known from the prior art components are used and no additional components are required for the additional function.
  • Embodiments of the invention provide a lock for a vehicle door which has at least one opening mechanism which can be coupled to a first drive, a clutch which can be mechanically transferred from at least one manual actuating element into a force-transmitting state and, in the force-transmitting state, the at least one opening mechanism with the first drive (20) couples, a second drive coupled to a securing element, wherein the securing element in a first stationary position blocks a manual actuation via an inner actuating element, and an evaluation and control unit which outputs corresponding control signals to the first drive and the second drive.
  • the second drive transfers the coupling from a separating state into the force-transmitting state via a force transmission element.
  • vehicle locks comprise at least one locking device designed as a catch.
  • the rotary latch encloses a bolt, whereby a locked state can be realized.
  • the locked state is understood below to be the state in which an actuation of an external actuating element is ineffective. That is, the vehicle door can not be unlocked or opened by operation of the outside operating member.
  • the locked state can also be distinguished by a secure and an unlocked state.
  • the inner actuating element In the secured locked state, the inner actuating element is ineffective in addition to the external actuating element. This state is achieved by the securing element being in the first stationary position, in which a transmission of the manual actuation of the inner actuating element to the closing device is prevented. Thereby, the vehicle door can not be unlocked or opened by operation of the inner operating member.
  • the unsecured locked state a transmission of the manual operation of the inner actuator to the locking device can be carried out and the vehicle door can be opened via the inner actuator.
  • the lock By the operation of the inner actuating element, the lock is at least unlocked, so that the vehicle door can be opened.
  • the catch can be rotated.
  • the operative connection between the inner actuating element and the rotary latch can be made directly mechanically, for example via lever connections, etc., or indirectly by electrical or electronic signals and a corresponding drive.
  • the electrical or electronic signals can be generated for example by evaluating sensors and limit switches, which detect the position of the manual actuating element.
  • the locked state can be canceled, for example, via a remote control, wherein the first drive is activated via a corresponding wirelessly transmitted signal and drives the catch.
  • the remote control generates the wireless transmitted signal, for example, in response to a manual operation of an operating element of the remote control.
  • a closed state of the vehicle door hereinafter the state understood in which the vehicle door is closed but not locked. This means that the vehicle door does not spring open while driving but can be opened when the actuators are actuated.
  • the vehicle may also have a child safety device, which makes a manual operation of the corresponding inner actuating element ineffective in the locked state.
  • the vehicle door In the open state of the lock, the vehicle door can be swung open. To undercut the opening process, the catch may push the vehicle door away from the vehicle frame, thereby opening the vehicle door a gap. So far, the opening process can only be facilitated if the clutch is mechanically engaged via the manual actuation elements. This allows the first drive to continue to rotate the catch such that the catch releases the vehicle door and the vehicle door is opened or pushed open. When a remote control is operated, the clutch is not engaged and the vehicle door is only unlocked but not opened.
  • the clutch can be advantageously inserted based on an electrical opening signal via the second drive, whereby an automated opening of the vehicle door is made possible via the first drive.
