Abstract
An ignition switch structure for preventing a key from being pulled by mistake comprises a lock core, a lock casing assembly for fixing the lock core, an ignition key and a lock blade arranged in the lock casing assembly to be matched with the ignition key. The lock blade returns through a returning spring with one end pressed on the lock core. The ignition switch structure is further provided with a safety sliding block for controlling the lock blade to move and a returning block. A first boss is arranged on the safety sliding block, a step surface and a groove is arranged on the returning block matched with the first boss, and a sliding block returning pressure spring is arranged between the safety sliding block and the lock casing assembly. When the first boss is contacted with the step surface, the safety sliding block is separated from the lock blade, and the ignition key can be pulled out; and when the first boss is contacted with the groove, the safety sliding block and the lock blade are in press fit, and the ignition key and the lock blade are locked out. The ignition switch structure can effectively prevent the key from being pulled out by misoperation and is reasonable in structural design, high in strength and long in service life, relaxation time of a manual button is long, and the ignition switch structure is safe to use and can be widely applied to the field of ignition key anti-mis-pull.
Description
Technical field
The utility model relates to a kind of automobile ignition switch, relates in particular to a kind of band key mistaken-pulling preventing ignition switch structure.
Background technology
Ignition lock is requisite in the car load of automobile, general ignition lock is divided into 4 gears, be LOCK, ACC, ON, ST, key just can be extracted when ignition lock is in the LOCK shelves, and vehicle in the process of moving, key is in the ON shelves, if vehicle in the process of moving or in the situation that do not come to a complete stop, forwards the LOCK shelves to and extracts key, can cause the steering hub column locking, steering wheel does not rotate, and causes easily the generation of traffic accident.
Number be 201120424445.4 to disclose a kind of steering lock with key mistaken-pulling preventing structure such as Chinese patent application, aim to provide and a kind ofly can some prevent the steering lock internal mechanism that key is extracted by mistake, its technical scheme main points are, a kind of steering lock with key mistaken-pulling preventing structure, comprise the steering lock body, described steering lock body is built-in with lock core, lock core is provided with lockhole, described lock core and steering lock body slide and arrange, lock core is provided with the return spare for its return, be provided with block between lock core and the steering lock body, when being provided with lock core shaft to inside slip on the lock core and block breaks away from and lock core shaft during to outside slip and the spacing lock core positive stop lug boss of block.But this is simple in structure, after the boss wearing and tearing, just can not play the function of false pull prevention, and key must rotate to the LOCK shelves and just can extract.
The utility model content
The purpose of this utility model provides a kind of band key mistaken-pulling preventing ignition switch structure, and it is easy to wear to solve the firing key mistaken-pulling preventing structure, the problem that the life-span is short.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of band key mistaken-pulling preventing ignition switch structure, comprise lock core, the lock housing assembly of fixed lock core, firing key, be arranged on the lock blade that cooperates with firing key in the lock housing assembly, also be provided with safe sliding block, the return piece of control lock blade activity; Be provided with the first boss on the safe sliding block, and be provided with step surface and groove on the return piece that the first boss matches; Described safe sliding block and lock housing inter-module are provided with the slide block recoil press spring;
When the first boss contacted with step surface, safe sliding block separated with the lock blade, and firing key can be extracted; When the first boss contacts with groove, safe sliding block and the pressing of lock blade, firing key is locked with the lock blade.
Extract dead time before the key for prolongation, be provided with the hand push button that the control safe sliding block moves at described safe sliding block.
For safe sliding block is separated and pressure with the lock blade on the different gears of ignition switch, described return piece one side pressure is on the end face of lock core, and the other end links to each other with the lock housing assembly by recoil press spring; Be provided with the second boss that control return piece moves at the lock core end face.
The beneficial effects of the utility model: by step surface and the groove fit of the boss on the safe sliding block and return piece, realize the lock blade is unclamped with locked, the control firing key separates with locked with the lock blade, and structural reliability is high, and is not fragile; Described hand push button can prolong the time that key is extracted, and guarantees key to be extracted after automobile comes to a complete stop again, and simultaneously, hand push button makes things convenient for the use of firing key so that firing key all can be extracted on various gears; Described return piece cooperates with the second boss, so that can determine firing key and the matching relationship of locking blade according to different gears, and simple and reasonable.
Below in conjunction with drawings and Examples, the utility model is described in further detail.
