Description
Technical field
The utility model relates to a kind of motor cycle ignitor, and especially a kind of motor cycle ignitor with anti-theft feature belongs to technical field of motorcycles.
Background technique
The igniter of common motorcycle comprises: ignition control circuit and ignition switch, at present, ignition control circuit is CDI (Condenser Drode Ignite most often, the di-cap igniting) ignition control circuit, its circuit diagram as shown in Figure 1, this control circuit comprises controllable silicon SCR, charging capacitor C1, commutation diode D1, D2, special ignition chip CS4213GP, two switching circuits of being made up of triode BG1, BG2 respectively.At the silicon controlled positive pole, i.e. normally-closed contact K21 in the ignition switch 2 in the connection diagram 3 between extinguish end SW and the grounding end GND; Because ignition control circuit separates with ignition switch, they connect by lead physically, Fig. 2 is the lead-in wire connection diagram of general point firearm and spark coil, magnetogenerator winding, the terminal 60,61 of the ignition switch 2 among the figure constitutes normally opened contact K22, terminal 64,65 constitutes normally-closed contact K21, Fig. 3 is the control block diagram of general point ignition system, and the working principle of common motor cycle ignitor is described in conjunction with Fig. 2, Fig. 3:
The charging winding 11 of magnetogenerator 1 is connected with the charging end EXT of ignition control circuit 13, the triggering winding 12 of magnetogenerator is connected with the trigger signal end PC of ignition control circuit 13, the discharge output terminal IGN of ignition control circuit 13 is connected with the elementary winding of spark coil 14, the extinguish end SW of ignition control circuit 13 is connected with the end of a normally-closed contact K21 in the ignition switch 2, the other end ground connection of this normally-closed contact K21, the positive pole of the termination storage battery of one normally opened contact K22 of ignition switch 2, the other end is connected with the power end of other circuit.Because ignition switch is what to separate with ignition control circuit physically, so ignition control circuit, magnetogenerator connected by lighting outlet with being connected all of ignition switch.
When ignition switch 2 is opened, normally-closed contact K21 is an off state, normally opened contact K22 is a closed state, when the flywheel of magnetogenerator 1 rotates, the charging voltage of its charging winding 11 output alternations, commutation diode D1 is a direct current with this AC rectification, be charging capacitor C1 charging, when triggering winding 12 output trigger signals to ignition control circuit 13, igniting intergrated circuit CS4213GP outputs signal to controllable silicon SCR, make the controllable silicon SCR conducting, charging capacitor C1 discharges to the elementary winding of spark coil 14, by coupling, induces high voltage at secondary windings, ignition function is finished in discharge on spark plug 3; The contact that is connected with storage battery is in closed state, and other circuit obtain power supply by this contact.
When ignition switch is not opened, the state of its contact does not change, normally-closed contact K21 will draw flame-out line from the joint of diode D1 and charging capacitor C1 and ground wire is connected, corresponding diagram 1, diode D1 can not rectification, can not be charging capacitor C1 charging, and the both positive and negative polarity of controllable silicon SCR is connected together, can not work, ignition control circuit 13 does not have discharge voltage output, fail to start; The contact K22 that is connected with storage battery is in off state, can not provide power path for other circuit, and other circuit are not worked.
In sum, the ignition switch in the general point firearm only plays two effects, and one is the power switch effect, and another is igniting/flame-out effect, but does not have antitheft effect.When ignition switch is not opened, if the cracksman disconnects flame-out line, simultaneously power contact is connected, promptly can start motorcycle, car is driven away.In order to prevent that the robber from stealing motorcycle, general motorcycle will additionally add alarm in addition, and this not only makes its complex structure, also needs the motorcycle user to spend an extra expense; The more important thing is that as product independently, general thief can learn very easily that alarm is used for the antitheft principle of motorcycle, can destroy alarm easily, steals vehicle.
