Ignition switch structure with key false pulling preventing function
The invention provides an ignition switch structure with a key false pulling preventing function. The ignition switch structure comprises a lock core, a lock casing assembly and a lock sheet, wherein the lock sheet is arranged in the lock casing assembly and is matched with the lock core, the lock sheet is reset by a lock sheet spring of which one end is pressed on the lock core, and the lock core can slide along the axial direction and rotate along the circumferential direction in the lock casing assembly. 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.
