Background technique
Ignition switch is absolutely necessary in the car load of automobile.It is 4 gears that ignition switch is divided into, i.e. LOCK, ACC, ON, ST shelves.The tradition ignition switch does not have latch functions, therefore, in the automobile traveling process, ignition key can forward any gear to, the driver is often because in the unwitting situation, the rotation ignition key of mistake causes the interruption of ignition switch function, affects the working life of motor and the use safety of car load.Be that CN1873871A discloses a kind of operation equipment for vehicle ignition switch such as China Patent Publication No., this device comprises for the ignition switch that changes translative mode according to the rotation of rotary member, the operating grip that is connected and can arrives the rotating operation on a plurality of pivotal positions that comprise on positi with rotary member, the plunger that can be between the position that the position that allows operating grip to rotate and quiescing handle rotate mobile barrier structure and having is connected with barrier structure also drives barrier structure to the locational solenoid valve that allows the operating grip rotation by ID identification with according to the electric current supply, wherein this device comprises retaining member, this retaining member is used for after ID identification moving in order to forbid it at the plunger of operating grip to the operation maintenance solenoid valve of on positi.This device solves because ignition noise and the friction damage problem that vehicle vibrations cause, but can not prevent that the driver is owing to not noting running into key or rotation key, ignition switch is on the incorrect gear, thereby causes the damage of motor or affect traffic safety.
The model utility content
The purpose of this utility model provides a kind of ignition switch anti-misoperation structure, solves ignition switch gear arbitrarily change, easy human operational error's in automobilism problem.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of ignition switch anti-misoperation structure comprises the drive link that links with automobile ignition switch igniting lock core, shell; A solenoid valve also is installed on shell, and solenoid valve links to each other with the car load control unit by circuit, is provided with telescopic push rod in the solenoid valve, and push rod is deep in the shell inner cavity by the hole on the shell;
Be provided with the groove that cooperates with push rod at drive link, when the automobile variable speed gear box is in neutral position state lower time, car load control unit input signal is to solenoid valve, and solenoid valve conduction is retracted at the effect lower push-rod of magnetic force, and push rod separates with groove; When the automobile variable speed gear box is in the gear state lower time of advancing, car load control unit input signal is to solenoid valve, and solenoid valve disconnects, and push rod stretches out under the effect of solenoid valve inner spring power, and push rod is pressed in the groove.
Preferably, described drive link is comprised of large-diameter portion position and minor diameter part position, and described groove is arranged on large-diameter portion position and the step surface that the path position is connected.
Wrong flame-out in traveling process for preventing automobile, described groove is corresponding with the ACC gear of ignition switch, and groove is smoothly transitted on the step surface from deep to shallow along ON shelves direction, and groove is step transition along LOCK shelves direction.
For prevent that ignition switch is rotated in the traveling process between each gear, respectively the advance gear corresponding at described drive link is provided with the groove that cooperates with push rod.
The beneficial effects of the utility model: realize the switching of solenoid valve by the signal of car load control unit input, thereby realize the flexible of push rod, simple in structure, and can control the flexible of push rod according to the residing gear signal of gearbox, push rod groove flexible and on the drive link separates or cooperates, realize the locked of each gear of ignition switch, avoid the driver under Vehicular behavior, operate miss and ignition switch is on the incorrect gear, thus cause the damage of motor and affect traffic safety.Described groove is arranged on the step surface, and grooving processes is simple, and does not affect the intensity of drive link, and described groove can be opened on the ACC gear, prevents that ignition switch from rotating on the LOCK shelves, causes automobile flameout; Also can be on each ignition switch gear equal grooves, strictly control the operation error between the ignition switch gear, improve car load safety.

Embodiment
Embodiment 1:
Shown in Fig. 1-4, a kind of ignition switch anti-misoperation structure comprises the drive link 1 that links with automobile ignition switch igniting lock core, shell 2; A solenoid valve 3 also is installed on shell 2, solenoid valve 3 links to each other with the car load control unit by circuit, be provided with telescopic push rod 31 in the solenoid valve, push rod 31 is deep in shell 2 inner chambers by the hole on the shell 2, is provided with the groove 11 that cooperates with push rod 31 at drive link 1; Described drive link 1 is comprised of large-diameter portion position 12 and path position 13, and described groove 11 is arranged on large-diameter portion position 12 and the step surface 14 that path position 13 is connected.Described groove 11 is corresponding with the ACC gear of ignition switch, and groove 11 is smoothly transitted on the step surface 14 from deep to shallow along ON shelves direction, and groove 11 is step transition along LOCK shelves direction.
When the automobile variable speed gear box is in neutral position state lower time, car load control unit input signal is to solenoid valve 3, and solenoid valve 3 conductings are retracted at the effect lower push-rod 31 of magnetic force, and push rod 31 separates with groove 11; Ignition switch can go back to the LOCK shelves from the ACC shelves.If the automobile variable speed gear box is in the gear state lower time of advancing, car load control unit input signal is to solenoid valve 3, solenoid valve 3 disconnects, push rod 31 stretches out under the effect of solenoid valve 3 inner spring power, when ignition switch forwards the ACC shelves to, push rod 31 is pressed in the groove 11, because the effect of groove step, ignition switch can not be got back to the LOCK shelves from the ACC shelves.Therefore, must be in neutral position state lower time at gearbox, from can the time ignition switch get back to the LOCK shelves from the ACC shelves, prevent that operation error from making motor undesired flame-out in running, affects engine performance and car load safety.
