Below in conjunction with the drawings and specific embodiments the utility model is further specified.
Figure is a kind of automotive ignition locking device STRUCTURE DECOMPOSITION figure of the present utility model.
Wherein: 1, mechanical key; 2, knob; 3, lock core cover; 4, centre circle pressing plate; 5, centre circle; 6, lock core; 7, connect rotating shaft; 8, locking fork; 9, electromagnet unit; 10, housing cover; 11, base housing; 12, steering wheel dead bolt; 13, dead bolt slide block; 14, dead bolt slide block cover plate; 15, signaling switch assembly; 16, slide block C; 17, slide block B; 18, slide block A.
Embodiment
Shown in figure, a kind of automotive ignition locking device is made of base housing 11 and housing cover 10, mechanical key lock set, electromagnetic lock assembly, signaling switch assembly 15 and handle lock assembly.In base housing 11, be provided with by lock core 6 and centre circle 5 and constitute the double-layer nested lockable mechanism that can rotate around the base housing axis.Be trapped outside lock core, between lock core 6 and base housing 11, and pass through the interlocking of key locking plate between the lock core 6.When inserting mechanical key, when opening between lock core, centre circle the interlocking locking plate, lock core can rotate relative to centre circle, realizes traditional key unlocking function.The electromagnetic lock assembly is made of the locking fork 8 that electromagnet unit 9 and electromagnet armature drive.The locking fork is under action of reset spring, and swing link end part inserts corresponding locked groove on the centre circle during initial position, pins centre circle.When the electromagnet energising, armature sucks, and when the drive fork was deviate from the centre circle locked groove, the centre circle release can be rotated.Need not to insert mechanical key 1 this moment, turns the knob 2 with the lock core interlock, and lock core can rotate with centre circle, realizes that ignition lock does not have (machinery) key unlocking function, and then can realize the keyless activation function.
The relative centre circle of described lock core can endwisely slip, and the tail end of lock core is provided with specific sloping platform; Described base housing has a slotted eye, and embeds a slide block C16 position that should sloping platform.When lock core during along the axial pressing action of centre circle, sloping platform can promote slide block C and outwards move; Signaling switch assembly 15 in the device is fixed on the base housing outside, and the push rod of switch is over against above-mentioned slide block C.When slide block C extrapolates, can back down this signaling switch, thereby can outwards export a request signal.When lock core shaft when resetting to the home position, slide block falls back to original height and position along sloping platform, switch disconnects.
Described lock core near caudal end part perpendicular to key slot direction, has a chute hole, embeds slide block A; To position that should slide block A, also have a chute hole, and embed another slide block B on the centre circle.When inserting key, utilize key thickness, can eject slide block A, and then promote slide block B.The position of corresponding slide block B is provided with slotted eye on the base housing, during the slide block B action, can partly enter this slotted eye.Thereby centre circle can be pinned, can't rotate.Simultaneously, the action of slide block B also can be backed down corresponding switch, can outwards export key and insert signal.
Described centre circle is provided with the lock groove of two sections cooperation electromagnetic lock mechanisms.The corresponding lock core initial position of first lock groove, when fork was in this section lock groove, centre circle can't rotate.Behind first lock groove interval certain angle stroke, be provided with second lock groove, in the time of in fork is in this section lock groove, centre circle can rotate in the certain angle scope.Suppose that the initial angle stroke is 0 degree, second section lock groove initial angle stroke is α, and maximum functional angle stroke is β, and then centre circle can rotate in the angle stroke less than β, but can't rotate back into 0 position greater than α this moment.
Described lock core cover 3 and centre circle pressing plate 4 except that playing lock core and centre circle axial limiting the function in base housing, also are provided with the track guide frame.Be achieved as follows function---lock core when initial position, directly spinning movement, lock core must be pressed down certain distance vertically after, could rotate to the single direction of setting.And after turning an angle, lock core is lifted to original height (axial coordinate) in the meeting axially under the guide frame effect.But on lift after, lock core can be rotated further the maximum angular stroke of setting; When lock core to back rotation when also having the position of certain angle apart from the home position, under the restriction of guide frame, do not press down as lock core, just can't be rotated further.Have only lock core is pressed down certain distance once more, avoid position limiting structure after, lock core could continue to go back to initial position (on the direction of rotation).
Described at the lock core breech face, be provided with the pit of given shape, and on the rotating shaft that drives the rotation of steering wheel dead bolt mechanism action and ignition switch, the convex of correspondingly-shaped arranged, this convex is inserted in the lock core tail end pit, and axially goes up mutual certain space in addition and can slide mutually.Such fit structure is different from traditional ignition lock, on the lock core breech face convex is set, and the structure of pit is set on rotating shaft.Its advantage is that when realizing said function, the required axial arrangement size of mechanism is shorter.
The signaling switch opening and closing sequential that the running track of lock core is triggered, setting in conjunction with the centre circle lock groove, can be achieved as follows logic function---do not have under the mechanical key insertion situation, lock core is pressing down and when the operative orientation of setting rotates, after turning an angle, can be directed to along lifting go back to home position (axial coordinate) on the axle, related signaling switch disconnects.When outside ECU (Electrical Control Unit) can be set at no switching signal disconnection, electromagnet quit work, and fork resets, and enter second lock groove on the centre circle, thereby the centre circle limited in rotation can't be got back to initial angle.When lock core is turned back to certain position, press down the pull switch conducting, after ECU (Electrical Control Unit) is received request signal, embed speed of a motor vehicle decision logic, only when the speed of a motor vehicle was lower than set point, control unit was just understood drive magnet work, the release centre circle, thus lock core and centre circle just can go back to initial position.Otherwise electromagnet is not worked, and centre circle is limited and can't gets back to initial position.So, when driving, be higher than a threshold value as the speed of a motor vehicle, then lock core and centre circle can't be got back to initial position, thereby the handle lock that driven by lock core can not eject locked steering wheel, not reason misoperation and influence traffic safety.
