Abstract

The electronic igniter for automobile has electronic pulse ignition circuit and mechanical lock with contact switch function assembled inside one casing, and the mechanical lock is opened and closed to control the electronic ignition module to be turned on and off. The dual functions of electronic continuous ignition and automobile anti-theft are achieved.

Description

The automobile burglar ignition

The utility model relates to the automobile burglar igniter.

Along with the development of China's automobile industry, in recent years, the stolen case of automobile increased gradually, thereby the stolen measure of various strick precaution automobiles appearred, if any on hand with on the vehicle window alarm is installed in automotive door, after automotive door or vehicle window were destroyed by force, alarm sounded the alarm.The shortcoming of this kind alarm is, the car stealer can destroy alarm, forces to connect ignition circuit and starts automobile.Along with the improvement of automotive ignition system, realized the combination of igniting continuously of the incompetent contact of automobile burglar and automobile again.Disclosing the continuous igniting of a kind of automobile as Chinese utility model patent specification CN2252244Y puts with the anti-theft integrated makeup of electronic cipher.It is made up of infrared photoelectric sensor, firing pulse controller and 15 electronic cipher anti-theft keys, and the firing pulse controller only when 15 passwords are entirely true, could be exported continuous ignition pulse signal under the control of infrared photoelectric sensor.This automobile is lighted a fire continuously and the shortcoming of electronic cipher anti-theft device is, cost height, complex structure, and the plug of 15 electronic ciphers and socket are easy to pass out of mind, and cause driver oneself to drive away their vehicles.

The purpose of this utility model provides compared with prior art a kind of, automobile burglar ignition simple in structure.

The purpose of this utility model is achieved in that the contact switch mechanical lock that access has the line switching function in the circuit of contactless automobile electronic impulse ignition apparatus.After mechanical lock was closed, the electronic ignition circuit was disconnected by force, and automobile can not start; Have only use with the key of phase-locked coupling lock is opened after, the electronic ignition circuit just can be switched on.Electronic ignition circuit and mechanical lock are sealed in the metallic case, and only the lockhole with mechanical lock partly exposes.

Because the utility model has added the firm mechanical lock with line switching effect when having adopted the contactless electron pulse igniter, played reliable antitheft effect, can effectively prevent to start automobile, and have excellent pick-proof performance with the trimming method.Adopt the technical solution of the utility model, simple in structure, implement easily.

4. shaping 5. power amplifications 6. high pressure output

Below in conjunction with accompanying drawing the utility model is done detailed description, the utility model indication mechanical lock is selected for use is lock mechanical lock with contact switch function or similar device in zero device of telephone set.Key is inserted lockhole, and screw key makes mechanical lock S ₁Closure, the signal that electromagnetic sensor produces is through R ₄To N ₁Amplify the back to N ₂, N ₃The scmitt trigger circuit of forming.Become square signal through shaping, through P ₁After amplifying output, again by R ₁₀To N ₅, N ₆Carry out power amplification, drive high-voltage ignition coil T ₁Produce needed high tension ignition pulse; When the derotation key makes S ₁During disconnection, pulse signal interrupts, N ₃Conducting, P ₁Conducting is through R ₁₀Current limliting, N ₅Conducting, N ₆End the output of spark coil no pulse.

Can know mechanical lock S by inference by Fig. 1 ₁Can insert on arbitrary branch road, as long as S ₁When closed, T ₁Can export firing pulse, S ₁After the disconnection, T ₁No pulse output gets final product, as shown in Figure 2.

In addition; the utility model is not limited to above mode of execution; as long as in automotive electronic igniter spare, utilize mechanical lock to combine with electronic ignition module with contact switch function, play antitheftly and the electronic ignition effect, all drop within the utility model protection domain.
