Definitions

  • the present invention relates to an electrical locking device, in particular a hood or a trunk door of a motor vehicle, by means of an electric lock of the armament type comprising a movable bolt assembly actuated from a gearmotor capable of picking up a keeper mounted on a fixed part of the body.
  • hood opening and closing operations generally require more or less restrictive manipulations; it is therefore desirable to avoid manual intervention as much as possible in order to replace it with controlled mechanisms, without however resorting to solutions that are too costly or complicated.
  • the object of the invention is to create an automatic locking and unlocking of the hood allowing an easy approach and a softened presentation of the latter up to the first engagement notch of the lock, without having to apply the forces mentioned above.
  • the subject of the invention is an electrical locking device of the above type, essentially characterized in that the bolt assembly comprises, armed by a common spring, a lever for locking the strike plate and a lever for locking lever locking in the engaged position and in that it further comprises a rotary member controlling the preceding levers, driven in rotation successively in the direction of opening and in the opposite direction of closing by the output of the gearmotor, in response to electric current pulses.
  • the rotary control member can tilt around an axis perpendicular to its axis of rotation, with return by torsion spring either under the action of the locking lever coming into contact with an inclined ramp of the control, either by the action of an external opening lever, to allow manual control of the lock by releasing the locking and locking levers, in the event of a power failure.
  • the motorized assembly 1 is mounted on a movable panel, hood or trunk door, while the keeper 2, in the shape of a stirrup, is mounted on a fixed part of the bodywork.
  • Figure 1 shows schematically some points 3, 4 of fixing by conventional assembly means.
  • the electric lock comprises a geared motor 5 whose output shaft drives in sequence, by means of a rotary control member 6, a lever 7 for locking the strike plate and a lever 8 for locking the locking lever, these two levers being returned to the open position of Figure 1 by a common torsion spring 9 hung between said levers.
  • the locking lever 7 and the locking lever 8 pivot perpendicularly with respect to each other inside a box 10 made of folded sheet, around their respective axes 11, 12, the common return spring 9 being wound around the axis 11 of the locking lever.
  • the locking lever 7 has a hook-shaped nose 13 provided for the introduction of the keeper 2, a diametrically opposite notching zone, provided with two successive locking notches 14, 15 and a curved branch 16, terminated by a pin 17 likely to interfere with certain surfaces of the rotary control member 6 in order to pivot the locking lever 7 selectively in the direction of locking or unlocking of the strike.
  • the locking lever 8 has, for its part, a nose 18 engaging under the action of the spring 9 in one of the notches of the locking lever, according to the position of the latter, a curved branch 19 capable of interfering in turn with certain cams of the rotary control member and a branch subjected to the action of an external push-button 21 with manual control in order to rotate the locking lever 8 in the unlocking direction, that is to say that is to say of its disengagement with the locking lever 7 to release the latter upon opening.
  • the rotary control member 6 driven successively in both directions of rotation by the output of the gearmotor 5 is a part preferably made of molded synthetic material, affecting a compact shape but with very tormented contours, that is to say having a variety of bearing faces and cams of various shapes and controlling the respective movements of the aforementioned levers which constitute the moving assembly of the bolt assembly.
  • the different characteristic forms of the control member 6 will be described below with the operation of the device.
  • control member In addition to its rotation around the motor axis, the control member can tilt around an XY axis, in particular in the event of an electrical failure under the manual action of the external pusher 21 (FIGS. 9 and 10), the force of which application is transferred to the control member 6 by means of a manual opening lever 22 mounted pivoting about the hinge pin 12 of the locking lever 8 and pivoting in parallel with the latter.
  • This phase is accomplished by the reverse rotation (clockwise) of the control member, on an electrical opening impulse given remotely either from a contactor (not shown) inside the passenger compartment of the vehicle, or from an external contactor actuated for example by a boot key or by a push button.
  • the cam 24 of the control member 6 causes the disengagement of the locking lever 8 by rotating it in the counterclockwise direction ( Figure 6) by contact with the curved branch 19 of the locking lever .
  • the device In the event of an electrical failure, the device is designed to operate manually whatever the position of the control member 6 at the time of the failure.
  • control member 6 occupies an intermediate position other than the locked position of FIG. 7, it constitutes a hindrance to the pivoting of the preceding levers. This discomfort is avoided by tilting the control member at an angle "f j It (clockwise, FIG. 10) around its axis XY, by compressing a torsion spring 27 wound around its articulation.
  • the tilting of the control member is caused differently depending on whether it is the closing or opening of the lock.
  • the external pusher 21 acts simultaneously on the opening 22 and locking 8 levers to, on the one hand, tilt the control member 6 and, on the other hand, release the locking and locking levers 8.
