Definitions

  • the invention relates to a motorized device improved for opening a vehicle lock automobile.
  • the invention relates more particularly to a motorized device for opening a vehicle lock automobile, of the type comprising a control member which can be brought by a user from a rest position to a open position in which it controls the supply of an electric motor which drives a linkage according to a lock opening cycle.
  • the electronic control circuit must therefore use limit switches sensibly arranged in the device and include timing means and reversing the direction of the motor supply current electric.
  • the object of the invention is therefore to propose a device motorized opening which allows in particular to simplify the maximum electronic control circuit of the vehicle.
  • the invention provides a motorized device opening a motor vehicle lock, of the type comprising a control member which can be brought by a user from a rest position to an open position in which it controls the supply of an electric motor which leads to a linkage according to an opening cycle of the lock, the opening device comprising an actuator which is movable between a feeding position, in which the motor is electrically powered, and a cut-off position in which the motor supply is cut off, the actuator being brought from its cut-off position to its position supply by the control unit when the latter is brought by the user from its rest position to its position opening and, at the end of the lock opening cycle, the linkage brings the actuator back to its cut-off position, characterized in that the actuator is carried by the control on which it is movable between a relative position advanced, which it occupies when the actuator and the control are simultaneously in their respective positions of cut off and rest or simultaneously in their position supply and opening, and a relative position moved away that it occupies when the control member is in position the actuator is returned to the position break.
  • the device 10 which is illustrated in the figures is intended to ensure the opening of a lock (not shown) which keeps a vehicle leaf in the closed position automobile.
  • the device 10 is motorized in that it comprises a electric motor 12 which, when powered, causes the passage of a control linkage 14 of the lock of a state closing in an opening state in which the lock releases the opening which can then be opened.
  • the electric motor 12 also controls the return of the linkage 14 to an initial closing state in which the lock is brought into a state in which it is susceptible again to keep the sash in the closed position.
  • the user causes the opening of the lock by bringing a control member, here produced in the form of a pusher 16, from a position longitudinal retracted from rest, illustrated for example in Figures 2 and 3, in an advanced longitudinal opening position illustrated for example in Figures 5 and 6.
  • the pusher 16 is therefore slidably mounted along a longitudinal axis A1 in a box 18 which is illustrated more particularly in Figure 2 and which is intended to be fixed to a body element of the vehicle in such a way that the pusher 16 is accessible from outside the vehicle.
  • the linkage 14 which is arranged longitudinally in front of a front transverse wall 20 of the housing 18, comprises essentially a control wheel 22, a return lever 24 and a connecting rod 26.
  • the wheel 22 is rotatably mounted about its axis longitudinal A2, parallel to the sliding axis A1 of the pusher 16, and it is likely to be driven in rotation by the electric motor 12 including the motor shaft, of axis A3 parallel to axis A2, carries a pinion 28 which meshes with a external cylindrical toothed surface 30 of the wheel 22.
  • the return lever 24 is pivotally mounted around a axis A4, parallel to axes A2 and A3 of wheel 22 and of the motor 12, in a plane arranged longitudinally behind the wheel 22 but in front of the front transverse wall 20 of the housing 18.
  • the lever 24 includes a feeler finger 32 which is intended to cooperate with a cam 34 which is arranged in relief on a rear transverse surface 36 of the wheel 22.
  • the cam 34 has a lateral surface 38 which is offset by relative to the axis A2 of rotation of the wheel and the lever 24 is rotated around its axis A4 by means elastic (not shown) so that his finger probing 32 is in abutment, radially with respect to the axis A2, against the lateral surface 38 of the cam 34.
  • the probing finger 32 follows the profile of the cam surface 38 which rotates with the wheel 22 and, according to this profile, causes the return lever 24 to rotate about its axis A4.
  • Rod 26 is connected by one of its ends 40 rotating around an axis A5, parallel to axes A4 and A2, at lever 24 so that when it pivots about its axis A4, the rod 26 is driven substantially by a movement of translation according to its direction of elongation.
  • the other extremity (not shown) of the rod 26 being connected to the lock of opening it, the device 10 is thus capable of controlling the opening of the lock thanks to the linkage 14.
  • the motor electric 12 and the wheel 22 are intended to be received in a front housing 42 fixed in front of the housing 18.
  • the profile of the cam surface 38 of the cam 34 is such that a opening cycle of the control linkage 14 of the lock, which involves the transition from a closed state to a state opening and - a return to the initial closing state, corresponds to one complete revolution of wheel 22.
  • the electric motor 12 is always controlled in the same direction of rotation since, after a full revolution of the wheel 22, the feeler finger 32 finds itself in abutment against a portion of the control surface 38 which corresponds to the state of closing the lock; after going through the entire profile of the surface 38 which causes it to pass through a open position illustrated in Figure 16.
  • the power supply to the motor electric 12 is controlled by a switch 44 which, when in an open state, interrupts power to the motor 12 which then remains stopped, and which, in a closed state, allows current to flow through the supply circuit of the motor 12, which then causes the pinion to rotate control 28 and therefore of the wheel 22.
  • the power circuit of the motor 12 preferably include a second switch which will controlled for example by an electronic anti-theft control unit in function of locking or unlocking information supplied to the control panel by the user, for example a remote control.
  • the electric motor 12 will only supplied with current only if the two switches for example arranged in series in the supply circuit, are simultaneously in their closed state corresponding to an order prior to unlocking and then to an order to open the lock.
  • the pusher 16 does not act directly on switch 44, but by via an actuator 46.
  • the actuator 46 comprises essentially a main body elongated in the direction longitudinal A1 for sliding the pusher 16 and it is movable sliding in this direction between a position longitudinal cut-off and a longitudinal position feed forward in which it cooperates by a front longitudinal end 48 with switch 44 for bring it to its closed state in which it is susceptible to supply the electric motor 12 with current.
  • the actuator 46 is slidably mounted according to the longitudinal direction A1 in pusher 16.
  • the actuator 46 can therefore occupy an advanced relative position, when the actuator 46 and the control member 16 are simultaneously and respectively in their cut-off or rest position or, simultaneously in their feeding and opening position.
  • the actuator 46 can also occupy, with respect to the control member 16, a relative relative position in which it is located when the control member 16 is in the open position and that the actuator 46 is returned to the cut-off position.
  • Bistable elastic means are interposed between the actuator 46 and the pusher 16 to urge the actuator 46 towards one or the other of these two relative positions relative to pusher 16.
  • the device 10 comprises a pin 52 with two branches 54, 56 folded in a U.
  • the two branches 54, 56 extend substantially parallel in one direction transverse perpendicular to the direction of sliding A1 pusher 16 and actuator 46.
  • a first of the branches 54 is engaged in a corresponding orifice 58 arranged in the pusher 16 so that the pin 52 has no other possibilities that to pivot around this first branch 54 relative to the control member 16.
  • the second branch 56 is received at the same time in a corresponding orifice 60 arranged in the actuator 46 and in a longitudinal window 62 fitted in pusher 16.
  • the actuator 46 moves by compared to pusher 16, it therefore causes a rotation of the pin 52 around its first branch 54, but it causes also an elastic deformation of this pin 52 by bringing together its two branches 54, 56.
  • the orifice 58 in which is engaged the first branch 54 is arranged longitudinally substantially at the same level as the middle of the window 62 in which the second branch 56 moves. so, when the second branch 56 is longitudinally at middle of window 62, pin 52 is in its state of maximum deformation so that the system consisting of pusher 16 of pin 52 and actuator 46 is then in an unstable equilibrium position, the pin 52 then having tendency, by relaxing, to cause the displacement of actuator 46 to either of its relative positions forward or backward relative to pusher 16.
  • the actuator 16 has two front transverse arms 68 and rear 70 which are intended to cooperate with the wheel 22.
  • the arm transverse before 68 extends in a transverse plane which is arranged longitudinally in front of a front transverse face 72 of wheel 22.
  • the wheel 22 has, on this transverse face before 72, a flange 74 of axis A2 which is arranged in relief on the face 72 and which is provided with a notch 76.
  • the front transverse arm 68 is arranged longitudinally opposite either from the collar 74, or from the notch 76.
  • the collar 74 has a longitudinal thickness such that, when the arm 68 is facing the flange, the actuator 46 cannot be brought back towards its cut position. He can not be brought back to this position only when it is next to the notch 76 fitted in the collar 74.
  • the actuator 46 when the actuator 46 is in position cut back, the front transverse arm 68 is engaged in the notch 76 of the collar 74 and the arm 68 thus prevents the wheel 74 to be able to pivot around its axis A2 coming in press against the edges of the notch.
  • the rear arm 70 of the actuator 46 extends in a transverse plane which is arranged behind the face rear transverse 36 of the wheel 22.
  • the rear arm 70 has a transverse section at the free end of which is arranged a longitudinal section 78 which extends forward.
  • the rear transverse face 36 of the wheel 22 has a groove annular device 80 of axis A2 which is hollowed out.
  • the actuator 46 When the actuator 46 is in the advanced feed position, the longitudinal section 78 of the rear arm 70 is engaged in the groove 80.
  • the wheel 22 has a ramp 82 which is arranged in the groove 80 and which is intended to cooperate with the longitudinal section 78 of the rear arm 70 to cause the retraction of the actuator 46 to its retracted cut-off position when the ramp 82 of the wheel 22 arrives in coincidence with the rear arm 70
  • the pusher 16 and the actuator 46 are both in their remote position, respectively rest and break.
  • the actuator 46 is then in position relative advanced compared to pusher 16 as shown in the Figure 4 in which we can see that the second branch 56 of the pin 52 is in abutment against the front longitudinal end 64 of window 62.
  • the front transverse arm 68 is released from the notch 76 while the longitudinal section 78 of the rear arm 70 is engaged in throat 80.
  • the electric motor being supplied with current and the front transverse arm 68 being released from slot 76, the wheel 22 is therefore rotated about its axis A2.
  • the wheel 22 having started to pivot around its axis A2 under the action of the motor 12, the front transverse arm 68 of the actuator 46 is then opposite the flange 74 and, under the effect of the spring 84, the front transverse arm 68 is stressed in longitudinally backwards against the flange 74 which prevents the actuator 46 from returning to its position of cut, thereby preventing the pusher 16 from returning to its rest position. So even if the user does not submit the push button 16 only at a short pulse, once the cycle opening of the lock is started, it continues until its end. Indeed, the actuator 46 being held by the flange 74 in the feed position, the electric motor 12 continues to rotate the wheel 22 via the pinion of command 28.
  • pusher 16 and actuator 46 will be able to regain their respective rest and cut-off positions as soon as the wheel will have made a full revolution in such a way that the slot 76 again presents itself opposite the transverse arm front 68 of actuator 46.
  • the assembly of pusher 16 and the actuator 46 can then move back under the combined action of the return spring .84 and ramp 82 which, when it arrives in contact with the longitudinal section 78 of the rear arm 72, tends to push the actuator 46 backwards.
  • the electric motor 12 is no longer supplied with current and it stops spinning.
  • the device 10 then regained its state of rest and it is directly ready to perform a new operation to open the lock.
  • the ramp 82 tends to push the actuator 46 backwards. If the pusher 16 is held down, actuator 46 will be able to despite everything back to its cut position by moving relatively relative to the pusher 16 towards its axial position steephead Valley. Indeed, the orifice 58 of the actuator 46 drives then the second branch 56 of the pin 52, longitudinally backwards, in window 62 of pusher 16. In a first, this retraction of the actuator 46 will cause a bringing together the two branches 54, 56 of the pin 52, until the unstable equilibrium position described above, then the pin 52 will tend to participate also in the decline of the actuator 46 until its second branch 56 comes in support against the rear longitudinal end 66 of the window 62. With respect to the pusher 16, the actuator 46 is then in its relative position moved back and, relative to the device 10, it is in its cut-off position in which the power supply the electric motor 12 is interrupted causing the stop of the wheel rotation 22.
  • the actuator 46 finds itself in its relative position advanced relative to pusher 16 and the device is again ready to cause the lock to open again.
  • a complete cycle opening and closing of the lock corresponds to one turn complete of wheel 22.
  • a complete cycle only corresponds to a fraction of the rotation of the wheel 22, for example a U-turn.
  • wheel 22 must have a suitable cam, which will be the symmetric occurrence around the axis A2, as well as two notches and two diametrically opposite ramps 82.
  • the device according to the invention considerably simplifies the control circuit of the electric motor. There is indeed no provision for taking account of information from end-of-life sensors race. There is also no provision for a time delay operation of the motor or current reversing device feed.
  • the device 10 according to the invention proves to be simple and economical to implement, while ensuring the same functions than the devices of the prior art.
