The ignition switch structure is characterized in that a positioning bolt is further arranged on the lock casing assembly and is used for controlling the vertical movement of the lock core, a first boss is arranged on the lock core and is abutted against the positioning bolt to prevent the axial slide of the lock core, a limiting plate is arranged between the lock casing assembly and the lock core, and is elastically moved along the axial slide direction of the lock core, a second boss is arranged on the lock core and is matched with the limiting plate, a guide press-down inclining surface and a limiting surface are arranged on the second boss, the guide press-down inclined surface is used for pressing down a retaining plate when the lock core rotates, and the limiting surface is matched with the retaining plate to stop the rotation of the lock core when the lock core rotates. The ignition switch structure is used for effectively preventing the false pulling of a key from a steering lock.
Description
Technical field
The present invention relates to a kind of automobile ignition switch, particularly relate to a kind of ignition switch structure with key mistaken-pulling preventing.
Background technology
In the car load of automobile, ignition lock is requisite, general ignition lock is divided into 4 gears, i.e. LOCK, ACC, ON, ST, when ignition lock is in LOCK shelves, key just can be extracted, vehicle in the process of moving, key is in ON shelves, if vehicle is in the process of moving or in the situation that do not come to a complete stop, forward LOCK shelves to and extract key, steering hub column locking can be caused, steering wheel does not rotate, easily cause the generation of traffic accident, namely ignition lock needs one to prevent key by the mechanism of pulling out by mistake, when key is returned back to LOCK shelves by needs, directly during revolution, key can not be rotated.
Summary of the invention
The object of this invention is to provide a kind of band key mistaken-pulling preventing ignition switch structure, can effectively prevent key from pulling out from steering lock by mistake.
For above problem, provide following technical scheme: a kind of ignition switch structure with key mistaken-pulling preventing, comprise lock core, lock housing assembly, be arranged on the locking plate coordinated with lock core in lock housing assembly, the locking plate spring that locking plate is pressed on lock core by one end realizes return, and lock core can slide axially in lock housing assembly and circumference rotates setting; It is characterized in that: described lock housing assembly is also provided with and controls the up and down location embolus of lock core, on lock core arrange be butted on location embolus stop its first boss in axial sliding, the limiting plate arranged to elasticity activity in glide direction in lock core shaft is provided with between lock housing assembly and lock core, lock core arranges the second boss of coordinating with limiting plate, and on the second boss, when lock core rotates, it presses down inclined-plane to the guiding that gear plate presses down and coordinates with gear plate when lock core turns round and stops its pivotal confined planes in setting.
The present invention is also set to further, described lock housing assembly being arranged the limiting plate loose slot for making gear plate movable within it, arranging the spring corresponding with limiting plate in limiting plate loose slot.
The present invention is also set to further, and described lock housing assembly arranges the circumferential loose slot corresponding with the second boss, and described circumferential loose slot is communicated in the upper end of limiting plate loose slot.
Beneficial effect of the present invention, key inserts after in lock core, due to coordinating of location embolus and the first boss, lock core can not slide axially, realize unblanking by rotational lock core, in the process of rotational lock core, the guiding of the second boss presses down inclined-plane and drives limiting plate to regain in limiting plate loose slot, when the second boss is after limiting plate, limiting plate ejects and coordinates with the confined planes of the second boss under the driving of spring, realize the locking of lock core at gyratory directions, namely now lock core can not normally turn round, key can not be pulled out, now because the first boss loses coordinate with location embolus, lock core can by sliding axially in lock housing assembly, namely by pressing down key, confined planes and the limiting plate of the second boss realize being separated, now lock core can be carried out return back to initial LOCK position, now can realize the plug of key.

Detailed description of the invention
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples for illustration of the present invention, but are not used for limiting the scope of the invention.
Shown in composition graphs 1 to Fig. 4, a kind of ignition switch structure with key mistaken-pulling preventing, comprise lock core 3, lock housing assembly 2, be arranged on the locking plate 4 coordinated with lock core 3 in lock housing assembly 2, the locking plate spring that locking plate 4 is pressed on lock core 3 by one end realizes return, and lock core 3 can slide axially in lock housing assembly 2 and circumference rotates setting, lock housing assembly 2 is also provided with and controls the up and down location embolus 6 of lock core 3, on lock core 3 arrange be butted on location embolus 6 stop its first boss 31 in axial sliding, the limiting plate 5 that elasticity activity is arranged on lock core 3 slides axially direction is provided with between lock housing assembly 2 and lock core 3, lock housing assembly 2 is arranged limiting plate 5 loose slot 21 for making gear plate movable within it, in limiting plate 5 loose slot 21, the spring 51 corresponding with limiting plate 5 is set, lock core 3 is arranged the second boss 32 coordinated with limiting plate 5, lock housing assembly 2 is arranged the circumferential loose slot 22 be convenient to the second boss 32 circumference and rotated, circumference loose slot 22 is communicated in the upper end of limiting plate 5 loose slot 21, second boss 32 is arranged when lock core 3 rotates that it presses down inclined-plane 321 to the guiding that gear plate presses down and coordinate with gear plate when lock core 3 turns round and stops its pivotal confined planes 322.
Operating principle of the present invention, key 1 inserts after in lock core 3, due to coordinating of location embolus 6 and the first boss 31, lock core 3 can not slide axially, realize unblanking by rotational lock core 3, in the process of rotational lock core 3, the guiding of the second boss 32 presses down inclined-plane 321 and drives limiting plate 5 to regain in limiting plate 5 loose slot 21, when the second boss 32 is after limiting plate 5, limiting plate 5 ejects and coordinates with the confined planes 322 of the second boss 32 under the driving of spring 51, realize the locking of lock core 3 at gyratory directions, namely now lock core 3 can not normally turn round, key 1 can not be pulled out, now because the first boss 31 loses coordinate with location embolus 6, lock core 3 can slide axially in lock housing assembly 2, namely by pressing down key 1, the confined planes 322 of the second boss 32 realizes being separated with limiting plate 5, now lock core 3 can be carried out returning back to initial LOCK position, now can realize the plug of key 1.
The above is only the preferred embodiment of the present invention; should be understood that; for those skilled in the art; under the prerequisite not departing from the technology of the present invention principle; can also make some improvement and modification, these improvement of above-mentioned hypothesis and modification also should be considered as protection scope of the present invention.
