Definitions

  • the present invention relates to a device for locking a vehicle trunk door automobile.
  • Modern motor vehicles including high-end vehicles, generally have a system centralized locking of the opening which ensures, in particular by means of a remote control device infrared, locking in the closed position or unlocking of the various locks fitted to the opening of the vehicle and in particular the access doors to the passenger compartment and the boot lid or the tailgate.
  • Each of the locks fitted to the doors can also be operated manually, in particular by means of a key acting on a lock to manually trigger the locking and unlocking of the lock.
  • the trunk door or the tailgate can therefore be unlocked either by means of the lock or by means of the remote control system for simultaneous unlocking openings.
  • the trunk door When the driver has caused the opening of windows of the vehicle by means of the remote control device, the trunk door is in the unlocked position regardless either the means previously used by the driver for the lock in the closed position, i.e. either by means a key acting on a lock, either by means of the device remote control.
  • the object of the present invention is to provide a locking device which makes it possible to remedy the disadvantages which have just been mentioned.
  • the device 10 illustrated in particular in Figure 1 comprises a stator 12 which is produced in the form of a cylindrical housing comprising a rear part 14 and a front part 16 of larger diameter.
  • the cylindrical peripheral wall of the rear part 14 of the housing 12 includes means 18 for fixing and immobilizer rotating on a trunk door (not shown).
  • the rear part 14 is a hollow cylinder which receives internally rotating a manual actuating rotor 20 of which the rear part 22 is in the form of a socket cylindrical with surface portions 24 for its rotation guide inside the rear part 14 of the case 12.
  • the hollow rear part 22 is designed to receive a lock (not shown) whose barrel is linked in rotation to rotor 20 and whose rotation can be controlled manually by means of a key.
  • the rear part 22 of the manual actuation rotor 20 is extended by a smaller intermediate portion 26 diameter and by a front actuation part 28.
  • the intermediate part 26 is a cylindrical part which is rotatably received in a corresponding bore 30 formed in the partition 32 which separates the rear 14 and front parts 16 of the housing 12 forming a stator.
  • the front actuation part 28 has two fingers diametrically opposed actuation 36 and ends with a small diameter end shaft 38 having a groove 40 designed to receive a closing circlip 42.
  • the manual actuation rotor 20 also includes a control finger 44 which extends axially from the intermediate partition 46 delimiting the rear parts 22 and intermediate 26 of rotor 20 and which is radially eccentric relative to the axis X-X common to the rotor 20 and the stator 12.
  • control finger 44 extends to through an annular arcuate passage 48 formed at through the intermediate partition 32 and which extends in the front part 16 of stator 12 with an upper arcuate profile circle 50 used to guide the control finger in rotation 44.
  • the control finger 44 which is produced from material with the rotor 20, can thus move angularly in the annular housing 48 between two angular positions opposites delimited by the ends 52 and 54 of the housing.
  • the front part 16 of the stator 12 has a pivot 56 arranged above the housing 48 which extends axially parallel to the X-X axis from the intermediate partition 32 towards the front of the stator.
  • the pivot 56 is designed to receive a latch 58 in form of rocker with a hole 60 for mounting on pivot 56.
  • the latch 58 has a first control arm 62 which extends circularly above the housing 48 and whose curved underside 63 is capable of cooperating with the upper peripheral surface 45 of the control finger 44.
  • the latch 58 has a second control arm 64 which extends circularly opposite the first arm of control 62 and the lower face 66 of which has a ramp inclined 68 which is likely to cooperate with the party lateral 43 of the external surface of the control finger 44 (see Figures 2 to 5).
  • the free end 70 of the second control arm 64 of the latch 58 has a notch 72 which is designed to receive one end 74 of a bistable leaf spring 76 of which the other end 78 is supported in a housing 80 of the stator (see in particular figure 3).
  • the free end 70 of the second control arm 64 is extends radially inwards by a locking spout 82 whose function will be explained later.
  • the lower part, considering the figures, of the front part 16 of the stator 12 comprises an annular housing open 84 which extends angularly and which is delimited by two radial angular abutment surfaces 86 and 88.
  • the lower housing 84 which extends axially towards the rear from the annular front end face 90 of the annular skirt 34 of the front part 16 of the stator 12, is designed to receive in rotation a guide block 92 formed on the rear face 94 of a rotary actuating member 96.
  • the guide block 92 has two radial surfaces 98 and 100 which are each likely to cooperate respectively with a radial abutment surface 86, 88 of the stator 12.
  • the guide block 92 also includes a portion concave cylindrical surface 102 which cooperates in sliding with the convex cylindrical surface portion opposite 85 which delimits the housing 84 radially inward.
  • the rotary actuator is essentially consisting of a disc-shaped body 104 which is provided to be rotatably mounted in the front part 16 of the stator 12 which includes for this purpose guide shoulders 106 in rotation.
  • the disc 104 is completed at the front by a disc of closure 108 made of material and of larger diameter which has a radial tab 110 comprising a hole 112 provided to receive the end of an actuating rod of a opening lock (not shown).
  • closure 108 constitutes a closure cover for the part before 16 of stator 12.
  • the rear face 94 of the main disc 104 has a drive disc 114 made integrally with the discs 104 and 108 and whose peripheral cylindrical edge 116 has a notch 118 angularly delimited by two surfaces stop radials 120 and 122.
  • the entire rotary actuating member 96 is crossed in its center by a hole 124 which is provided for allow the passage of the end shaft 38 of the rotor 20.
  • the rear drive disc 114 comprises also a double light 126 inside which can angularly debate the pins 36 of the rotor 20 between two extreme angular positions delimited by the surfaces radial ends 128 and 130 of each lumen 126.
  • the locking device 10 comprises a bistable spring 132 for elastic return in rotation of the rotary actuating member 96 relative to the stator 12.
  • Spring 132 is a wire spring, a first of which end 134 is received in a hole 136 formed in the face rear 94 of disc 104 of rotary actuator 96 and the other end 138 of which is received in a hole 140 formed in a portion 142 of the bottom of the front part 16 of the stator 12.
  • the device In the position illustrated in Figure 2, the device is in the unlocked position and at rest, i.e. that there is no action on the organ drive 96, nor through the fingers 36 of the manual drive rotor which is in its stable position of rest towards which it is recalled elastically in the two meaning by elastic means (not shown) belonging to the lock, nor by the motorized drive device in rotation of the rotary actuating member 96.
  • the locking latch 58 is spring-loaded by spring 76 to its high position rest in which the locking spout 82 does not interfere with the notch 118 and in which the lower surface 63 of the control arm 62 bears against the circular edge 116 of the drive disc 114.
  • the rotary actuating member 96 is recalled elastically towards its extreme angular position of release in which the radial abutment surfaces 100 and 88 are in mutual support.
  • the pins 36 are in contact with the surfaces radial 130 of lights 126 and drive in rotation, in anti-clockwise, the rotary actuating member 96 up to a first intermediate position illustrated in figure 3.
  • control finger 44 cooperates with the underside 63 of the control arm 62 of the latch blocking 58 to cause the latter to pivot around the pivot 56 clockwise until the free end of the blocking spout 82 comes into contact with the edge 116 of the drive disc 114.
  • the bistable spring 76 also crosses its position unstable intermediary and now requests the latch locking 58 in pivoting clockwise.
  • the bistable return spring 132 is in a unstable intermediate position and actuator 96 is located in an intermediate position between its two extreme angular positions.
  • the control finger 44 occupies an angular position extreme in the housing 48 near the end face 52 of the latter.
  • the rotary actuating member 96 is in its extreme stop position corresponding to the locking of the lock fitted to the vehicle trunk door and in which the radial abutment surfaces 86 and 96 are in abutment mutual.
  • Manual locking operation ends when the driver releases his action on the drive rotor manual and remove the key, the rotor being recalled resiliently to its rest position illustrated in the figure 5 in which the diametrical drive pins 36 are at again in abutment against the radial end surfaces 128 lights 126 of the actuating disc 114.
  • the driver causes simultaneous unlocking of all the openings of the vehicle by means of its device unlocking remote control, it cannot cause simultaneously unlocking the trunk door by through the motorized drive device in rotation of the rotary actuating member 96 because this rotation is prevented by the presence of the spout 82 of the latch blocking 58 in the notch 118.
  • the unit rotary actuator 96 therefore always occupies its position extreme locking shown in Figure 5 to which it is spring-loaded by the bistable return spring 132.
  • the finger 44 is substantially at the right of the pivot 56 and it does not act on the control arm 62 or on the control arm 64.
  • the driver can then train freely again the rotary actuating member 96 clockwise corresponding to unlocking the lock by through the manual drive rotor whose pins opposite diametrics 36 cooperate with the end faces 128 lights 126.
  • the rotation motorized rotary actuator 96 is performed without interference with the remaining manual drive rotor immobilized in rotation, the relative position of the pins diametric opposite 36 with respect to the radial faces 130 and 128 of the lights 126 being offset from the angular travel of the rotary actuating member 96 as can see it by comparing Figures 2 and 6.
