Definitions

  • the present invention relates to a door lock for motor vehicle, in particular an unlocking lock automatic upon opening, and more particularly a lock electric opening assistance and / or opening assistance conviction.
  • the mechanism for opening the lock is driven by a gear motor, an electromagnetic system or any other device equivalent which is incorporated in a waterproof part of the housing lock, to isolate the electrical components and gears from the dust, water and any foreign body that may enter in the lock when using the vehicle.
  • the mechanism electric opening assistance is generally controlled by door handles or door opening paddles which are equipped with a contactor, sensor, microswitch or any other detector which is connected by an electric cable to the assistance device when opening the lock, to transmit the opening order. Being given that the outer pallets or handles are subject to bad weather, it is necessary to make the opening detectors as well than their fully waterproof electrical cables and connectors, which strike the cost of the lock.
  • a first object of the invention is to propose a lock electric assisted opening which minimizes connections as well as sealing constraints, to reduce the cost of the lock.
  • the second object of the present invention is to provide a electric lock with assisted opening, the arrangement of mechanisms is perfected.
  • the door locks on the front and sometimes rear are usually equipped with a mechanism automatic unlocking on opening, when the user operates the interior door handle. Indeed, if a user drives in a condemned position, for example, so as not to risk being attacked when stopping at traffic lights, it is important that accident, he can easily get out of his vehicle without having to unlock the door first, before you can open it.
  • Another advantage is that the user, by operating the handle door interior, provokes in a single operation, both the unlocking and opening, when it would be quite unpleasant, for a user, to be obliged to unlock the door before be able to open it.
  • this automatic unlocking function at the opening also known as “override” is energy consuming because the energy required for unlocking is added to the energy required to open the the lock.
  • This energy can be supplied by a manual effort of the user for a fully mechanical lock, or by electrical assistance mechanisms for opening and unlocking, for an electric lock.
  • the third object of the invention is to provide a lock with automatic unlocking on opening which reduces energy to provide to perform such a function.
  • levers both electric and mechanical, have a plurality of levers: an opening lever exterior, interior opening lever, locking lever interior, an exterior locking lever, and one or more intermediate levers.

  • the lock is in its closed state and mechanically locked, because the arm 47 of the locking lever 41 has pushed the end piece 36 of the cable C in a direction substantially perpendicular to the actuating stroke of the cable C, so as to cause the end piece 36 to escape from the fork 35 of the emergency lever 32
  • the end piece 36 will slide along the arm 47 and the guide ramp 35 a of the fork 35, without driving the lever emergency 32, the lock can not be mechanically unlocked from the outside.
  • the cursor 37 linked to the cable C will move along the guide rails 38 and 39 and will come by its inclined face 37 to push the switch button 60 a of the external opening switch 60, but since the general power supply of the vehicle has not been activated, the electric motor 16 for assistance in opening will remain inactive, thus also prohibiting electric opening.
  • the contactor 60 can send an opening control signal to the electric motor 16 which causes the rotation of the wheel 22 clockwise.
  • the crank pin 24 abuts against the arm 11b of the control lever 11 and pushes it back, so as to rotate the control lever 11 counterclockwise in FIG. 5
  • the crank pin 24 pushes the arm 11 b of the control lever 11 until the finger 23 a comes to bear against the elastic end-of-travel stop 27.
  • the pivoting of the control lever 11 causes the pivoting of the external opening lever 9 in the retention compartment 3, clockwise in FIG. 4.
  • the external opening lever 9 is pushed back by its arm 9 has the finger 5 has the pawl 5 to rotate counterclockwise the pawl 5 which thus releases the bolt 4 which can pivot, in turn, counterclockwise to release the keeper.
  • the drive torque exerted by motor 16 will be maintained for a period of time determined by a time delay, to ensure that the crank pin 24 causes the pivoting of the control lever 11.
  • the worm 19 will be returned in opposite direction by a spiral spring (not shown), to bring back the wheel 22 and therefore, the crankpins 24 and 25 in their initial positions, to allow later opening.
  • the spiral spring is linked to the worm 19 and is wound up during driven by the motor 16.
  • the return spring in spiral for the worm 19 is arranged in the bearing 20. In this configuration, the control lever 11 returns to its position rest under the action of a not shown return spring.
  • the electric opening assistance device operates in the same way from the position of FIG. 7, in which the lock is in its closed state and mechanically locked.
  • the authorized user wearing a badge provided with a transmitter for transmitting a determined coded signal approaches the vehicle which is provided with a recognition system comprising a receiver capable of decoding the signal and turning on the power the vehicle's power supply, when the authorized user has been duly identified.
  • the electric motor 16 causes the lock to open, and the bolt 4 by its cam 4a causes pivoting in the anti-clockwise direction of the arm 54 to push the abutment piece 49 of the locking lever 41, rotating it clockwise, to bring it into an unlocked position.
  • Contactor 60 sends a control signal simultaneously to the motor 16 and to the motor 52, to cause simultaneously assistance in opening the door and unlocking others doors.
  • the user can mechanically open the lock after having unlocked it mechanically, for example, by the lock barrel, by pulling on the cable C on an overtravel, to drive through the end piece 36 the fork 35 of the emergency lever 32 which pivots clockwise in Figure 9 and is pushed back by the curved tab 31 of its arm opposite the pin 30 of the control lever 11, to rotate it counterclockwise, which causes the pivoting of the external opening lever 9, and therefore, the release of the bolt.
  • the arm 54 comes into contact with the stop 49 of the locking lever 41, due to cooperation between the cam 4a of the bolt 4 and the cam follower pin 13a of the lever 13.
  • crank pin 25 shown in Figure 5 does not present no particular utility here.
  • the electric motor 52 is reversible, in order to rotate the locking lever 41 in both directions, to bring it respectively in its condemned or unlocked position.
  • the motor shaft 51 of the electric motor 52 has its axis of rotation parallel to the pivot axis of the locking lever 41, while the motor shaft of the electric motor 16 has its axis of rotation perpendicular to the axis of the opening lever 9.
