Definitions

  • the present invention relates to an electric lock mechanism for locking and unlocking controlled by the boot door or the tailgate of a motor vehicle, by means of a motorized bolt locking a keeper when the door is closed.
  • Known devices use either a motorized strike or a motorized bolt for locking the lock.
  • the latter Being a motorized strike, the latter is arranged for example on the vehicle body and is connected to the engine while the bolt is on the door leaf or on the tailgate.
  • a locking lever actuated separately by an electromagnet must be added to the bolt, which requires the use of a second motor member and poses additional wiring problems to power the hinged door on the bodywork. of the vehicle.
  • the electric locking of the keeper takes place only after the latching of the bolt beforehand, which is obtained by manual closing of the door, before the compression of the seal.
  • the present invention aims to overcome the above drawbacks and to realize a locking and unlocking mechanism with fully electric control using a single drive member arranged rationally and economically on the vehicle body and coupled with a conventional mechanical control allowing to be able to continue using the lock in the conventional way in the event of a breakdown of the electrical installation.
  • the invention therefore relates to an electric lock mechanism of the above type, characterized in that the leaf of the door supports the fixed strike and the body supports the motor member comprising an electric motor controlled remotely by impulses and capable of rotating the rotary bolt and the locking lever associated therewith by means of two disengageable links actuated by the output shaft of the engine, in the manner of a crankshaft, in order to ensure automatically and successively for a half-turn of the motor output shaft, locking the strike plate and locking the bolt when the door is closed, then unlocking and unlocking the opening during the next half-turn, carried out in the same direction of rotation of the motor output shaft.
  • the motor uses conductive tracks to make a half-turn at each electrical control pulse according to two stable stop positions corresponding respectively to the locking and unlocking of the lock.
  • the electrical impulses can be given either from inside the vehicle or from the outside, on the one hand at closing by a contactor detecting the correct presentation of the keeper after the folding of the door and on the other hand at opening by a contactor actuated by the operation of the door's external control button.
  • a bar connecting the external door opening button to the locking lever allows manual unlocking of the lock in the event of a fault in the electrical circuit.
  • FIGS. 1 and 2 recognize the rear part of a motor vehicle comprising a trunk door or a tailgate 1 capable of being locked on the fixed body 2 delimiting the trunk, after crushing a seal 3.
  • the keeper 4 of the lock, of the caliper type and provided with a centering cone 5 is mounted under the hollow beam 6 of the box forming the rear part of the door, while a compact motorized member 7 of the electric lock is fixed inside the boot, on a second hollow beam 8 bordering the rear skirt of the vehicle, by means of a plate 9 supporting the complementary part 10 of the centering cone and the various components of the motorized assembly, namely ; an electric motor 11 equipped with a speed reducer and supplied by means of several conductive tracks, not visible in the figures but forming an integral part of the engine block shown and a rotary bolt 12 of the fork type 13 for the hooking of the stirrup 14 of the keeper in order to lock it, the bolt being able in turn to be locked by a pivoting lever 15, said to be locking, acting in the manner of a ratchet 16 on the outside contour of the bolt forming a ratchet.
  • the bolt 12 and its locking lever 15 are subjected to the actions of two respective return springs, not shown, so that the bolt tends to return automatically to its position of opening or of release of the keeper represented in FIG. 2, while the lever is constantly constrained against the cam 17 of the external profile of the bolt.
  • the bolt and its locking lever are connected to the output shaft 18 of the engine by means of two links 19, 20 perforated by slides 21, 22 to allow the sliding of the respective drive pins 23, 24 of the bolt and the lever during the dead races of the rods.
  • the drive pins 23, 24 are connected to the bolt and to the locking lever by means of two spacers 25, 26 shifting the movement of the rods towards a more open outside area.
  • the other ends of the links are articulated on two superimposed cranks 27, 28, shown diagrammatically in FIG. 2 in a single bar, connecting the articulations 29, 30 of the locking link 19 and of the locking link 20.
  • cranks eccentric the output shaft 18 of the engine so as to transmit to the links the movements of a crankshaft transforming the continuous circular movement into rectilinear alternative movements.
  • the locking lever 20 is connected to the output lever 31 of the button 32 for controlling the exterior opening of the boot by means of a bar 33 shown diagrammatically by a dashed line in order to manually actuate the locking lever 20 for the release of the strike, in the event of a fault in the electrical circuit.
  • a first contactor 34 secured to the body and disposed in the vicinity of the bolt detects the position of the striker 4 when it arrives on the circular path of the fork 13 of the bolt, by means of a trigger cam secured to the door at 35 in Figure 2.
  • a second contactor 36 is fixed on the path of the lever 3T of the external opening button to send a specific impulse to command the motor to unlock the bolt and unlock the strike for the opening of the door.
  • FIG. 1 shows the door open.
  • the electric lock according to the invention operates as follows, with reference to FIGS. 3 to 6.
  • the first quarter-turn of the motor has the effect of rotating the bolt 12 in the direction indicated using the rod 19, which causes the strike plate 4 to lock at the same time as the compression of the seal.
  • the locking lever 20, constrained by its spring, then slides on the cam 17 of the bolt until it is locked by the pawl 16.
  • the movement of the lever 15 is made free thanks to the slide 22 of the locking rod 20 which is then inoperative.
  • the position in FIG. 4 therefore corresponds to the locking of the keeper 4 and to the locking of the bolt 12.
  • the locking rod 20 pivots the corresponding lever 15 which releases the bolt 12 under the effect of its return spring.
  • the movement of the bolt is made free by the existence of the slide 21 of the locking rod 19 and by the displacement of this last to the right of Figure 6.
  • the keeper 4 is then unlocked and released from the grip of the fork 13, the relaxation of the gasket helping the release.
  • FIG. 3 With the passage to FIG. 3, stable position, brings the locking lever 15 in contact with the bolt 12 while the drive pin 23 of the bolt comes to the bottom of its slide 21, by the play of the links 20, 19.
  • FIG. 3 therefore corresponds to the unlocking of the lock, but moreover this ring is ready for reclosing by a new pulse according to the cycle previously described.
  • the electrical operation is coupled with a mechanical emergency control from the button 32 for external opening.
  • the lock can operate mechanically in a conventional manner, both when opening and closing by slamming the door. To this end, it is possible to disengage the motorization by uncoupling the locking rods 19 and locking 20 by the release of the drive pins 23, 24 through the respective buttonholes 37, 38 of the slides 21, 22.
