Embodiment 1

[0016] Such as Figure 1-4 As shown, an ignition switch anti-misoperation structure includes a transmission rod 1 linked with the ignition lock cylinder of the automobile ignition switch, and a casing 2; an electromagnetic valve 3 is also installed on the casing 2, and the electromagnetic valve 3 is connected to the vehicle through a circuit. The control unit is connected, and the solenoid valve is provided with a retractable push rod 31. The push rod 31 penetrates into the inner cavity of the casing 2 through the hole on the casing 2, and the transmission rod 1 is provided with a groove 11 that cooperates with the push rod 31; The transmission rod 1 is composed of a large-diameter part 12 and a small-diameter part 13 , and the groove 11 is arranged on a stepped surface 14 connecting the large-diameter part 12 and the small-diameter part 13 . The groove 11 corresponds to the ACC gear of the ignition switch. The groove 11 smoothly transitions from deep to shallow along the dire...

Embodiment 2

[0019] Such as Figure 5 As shown, grooves 11 cooperating with the push rod 31 are provided on each driving gear position of the ignition switch corresponding to the transmission rod 1 to strictly control the misoperation between the ignition switch gears, only when the transmission is in neutral. , the push rod 31 in the electromagnetic valve 3 is retracted under the action of the magnetic field force, and the ignition switch can be rotated to improve the safety of the vehicle. Others are the same as embodiment 1.

Abstract

An anti-misoperation structure for an ignition switch comprises a transmission rod which is linked with an ignition lock core of the automobile ignition switch and a shell; an electromagnetic valve is also installed on the shell, the electromagnetic valve is connected with main control unit through a circuit, a retractable push rod is arranged inside the electromagnetic valve, and the push rod extends into an inner cavity of the shell through a hole on the shell; and the transmission rod is provided with a groove which is matched with the push rod, when an automobile transmission case gear stays at a neutral gear state, the main control unit inputs a signal to the electromagnetic valve, the electromagnetic valve is conducted, the push rod is retracted under the effect of a magnetic field force, and the push rod is separated from the groove. Due to adopting the anti-misoperation structure for the ignition switch, the problems that the service life of an engine is influenced by easiness of the ignition switch on a non-corresponding gear caused by misoperation in the advancing process of a car can be solved, simultaneously the safety of the car can be improved, simpleness in structure is realized, and the anti-misoperation structure can be widely applied to the field of the ignition switch.

Description

technical field [0001] The invention relates to an ignition switch structure, in particular to an ignition switch anti-misoperation structure. Background technique [0002] The ignition switch is essential in the whole vehicle of the car. The ignition switch is divided into 4 gears, namely LOCK, ACC, ON, ST gear. The traditional ignition switch has no locking function. Therefore, the ignition key can be turned to any gear when the car is moving. The driver often turns the ignition key by mistake without knowing it, causing the interruption of the ignition switch function and affecting the engine. The service life and the safety of the whole vehicle. For example, Chinese Patent Publication No. CN1873871A discloses an operating device for a vehicle ignition switch, which includes an ignition switch for changing the conversion mode according to the rotation of the rotating member, connected with the rotating member and capable of reaching the position including the on positio...
