A telescopic structure for controlling the ignition switch deadbolt, comprising a housing, a turntable arranged in the casing to cooperate with the end of the ignition key lock cylinder, an action rod that rotates together with the turntable, a deadbolt assembly arranged on the action rod, and a deadbolt The assembly includes a lock tongue seat, which is fixedly connected with the lock tongue seat and cooperates with the steering column to lock the steering wheel. A hole is opened on the lock housing to allow the lock column to protrude; For the retractable stop pin, the action rod is provided with a disc to withstand the stop pin, and the disc is provided with a concave part; the cylindrical structure and the retaining ring with the same maximum diameter as the disc, and the rotation of the key drives the action bar and the disc. The disk rotates to control the up and down movement of the dead bolt assembly. The invention not only achieves good locking of the steering wheel, but also has a compact internal structure, and will not cause wear and abnormal noise due to the gap shaking between the parts, thereby improving customer satisfaction and the service life of the parts. The invention can be widely used in the field of automobile ignition switches.
Description
technical field [0001] The invention relates to an ignition switch structure, in particular to a structure for controlling the expansion and contraction of the ignition switch deadbolt. Background technique [0002] The automobile ignition switch includes a lock cylinder part and a transmission part connected with the lock cylinder part. The transmission part is usually provided with a locking mechanism that cooperates with the steering column to control the locking of the steering column. When the car is turned off and the key is pulled out, the ignition switch locks the steering wheel so that the car will not deflect and slip, ensuring safe parking. For example, the Chinese patent application number is 201120323779.2, which discloses an ignition switch assembly, including a housing, a lock cylinder mechanism, a transmission mechanism, an ignition trigger mechanism and a deadbolt mechanism installed on the housing, and the deadbolt mechanism includes a lock The transmissio...
