Abstract
An ignition switch is switched to the ON position for conducting a joint A and a joint B, the electric potential of a point b becomes equal to 12V of terminal voltage of a battery 1; the electric potential of a point c becomes the value subtracting 12V-Vz of the stipulated electric potential of breakdown voltage Vz of a voltage stabilizing diode 7 from 12V, upon which at the point c, two transistors 16,17 connected with a base are positioned at the ON position simultaneously, the electric potential of a permit signal terminal for ignition 10 changes from zero change to the permit potential for ignition, therefore, a coil driving loop 8 drives an ignition coil so as to start the engine. Even though the point b and the point c encounter short circuit or the point b or the point c is directly connected with the battery 1, the point c will not produce 12V-Vz of stipulated electric potential, and the engine can not be started. Therefore the engine ignition device is provided for vehicles that are hard to start the engines by non regular means.

Fig. 1～3 show the present invention the 1st embodiment, and Fig. 1 is the whole pie graph of engine ignitor; Fig. 2 is an ignition switch contact explanatory drawing; Fig. 3 is the engine ignitor circuit diagram.
Fig. 1 is the engine for two-wheel motor vehicle ignition mechanism, and this engine ignitor is by the battery 1 with 12V terminal voltage; Be connected with battery 1 and implement the ignition switch 3 of switch by ignition key by safety fuse cutout 2; Ignition mechanism 4 with electric current and voltage determination circuit; Spark coil 5; Engine ignition spark plug 6 constitutes.
As shown in Figure 2, ignition switch 3 has 4 fixed contact A～D; Rotation travelling contact E with the ignition key operations linkage; Fixed contact A and fixed contact D are on state when flat.2 immovable point A, the B mutual conduction when ignition switch 3 is in the ON position of relative configuration; And 2 immovable point C, the D mutual conduction when ignition switch 3 is in LOCK or OFF position that disposes relatively.Thereby when ignition switch 3 was in aforementioned each position, the on state of each fixed contact A～D was shown in Fig. 2 table.
As can be seen from Figure 3, the negative terminal of battery 1 is grounded on car body; And its positive terminal is connecting the fixed contact B of ignition switch 3.In addition, be connected reference diode 7 between the fixed contact A of ignition switch 3 and fixed contact C.
The coil driver 8 of ignition mechanism 4 comprises: the power supply terminal 9 that connects battery 1 when ignition switch 3 being placed the position of ON; The fire signal terminal 10 of input aftermentioned fire signal; The pulser coil tenminal block 11 that connects pulser coil; The spark coil tenminal block 12 of tie point fire coil 5; And the ground terminal 13 that is grounded on car body.
The igniting permission loop 14 that is provided with in the ignition mechanism 4 include with the idiostatic b of fixed contact A, D of ignition switch 3 and d point as grounding parts between the diode 15 of connecting and clamping; Pnp type the 1st transistor 16; Npn type the 2nd transistor 17; And resistance 18.
The emitter of the 1st transistor 16 is connected in the b point by diode 15; Its base stage is connected in the c time of ordering by resistance 19 and diode 22, is connected in grounding parts e point by resistance 20 again; Its collector electrode is connected in the collector electrode of the 2nd transistor 17.The collector electrode of the 2nd transistor 17 is connected in the collector electrode of the 1st transistor 16; Its base stage is connected in the c point by resistance 21, and its emitter is connected in d point as grounding parts by resistance 18 when being connected in igniting enabling signal terminal 10.
Bottom illustrates the effect of the embodiment of the invention with aforementioned formation.
When ignition switch 3 was in LOCK position or OFF position, fixed contact A, C, D point interconnected, and separated with the fixed contact B with 12V current potential, and therefore, the current potential that b point C is ordered all is that earthing potential is zero.Its result, the current potential of igniting enabling signal terminal 10 becomes zero, and coil drive loop 8 is drive ignition coil 5 not, and motor is inoperative.
Use ignition key to make ignition switch 3 be in the position of ON, fixed contact A, B interconnect, and b point current potential becomes the 12V that equates with a point.On the other hand, because the current potential that C is ordered becomes earthing potential zero, reference diode 7 is punctured by the voltage of the 12V more taller than breakdown voltage, and the current potential that c is ordered has become the regulation current potential 12V-V that breakdown voltage VZ determined of electric reference diode 7
Z
As a result, emitter of the 1st transistor 16 (current potential 12V) and base stage (current potential 12V-V
Z) between produce the potential difference of regulation, the 1st transistor 16 is in the ON position; Simultaneously, the base stage of the 2nd transistor 17 (current potential 12V-V
Z) and emitter (current potential be zero) between produce the potential difference of regulation, the 2nd transistor 17 is in the ON position.And, former be the potential change of zero igniting enabling signal terminal 10 near 12V, detect the coil driver 8 drive ignition coils 5 of this value, engine start.
So above-mentioned, use regular ignition key to make a switch be in the ON position, motor can start; But ought not use regular ignition key to make b point and the short circuit of c point, perhaps even with b point or c point be directly connected in battery 1, make the 1st transistor 16 and the 2nd transistor 17 ON position that can not exist together, thereby motor fail to start.
Like this, use reference diode 7, produce the current potential 12V-V of regulation as nonlinear element
Z, motor can start, and because aforementioned current potential 12V-V
ZMust be to use regular ignition key, make ignition switch be in the ON position and measure, therefore be difficult to make engine start with the method beyond regular.In addition,, do not need the latch cicuit of high price, can cheaply realize owing in the judgement of igniting permission, do not detect curtage variation in time.

And when ignition switch 3 was in LOCK position or OFF position, because the current potential that b point and c are ordered coexistence earthing potential zero volt, transistor 33 was not located the ON position, does not have electric current to flow through to electric current decision circuit 32 from ignition switch 3.When using ignition key to make ON position, ignition switch 3 place, the 12V that the current potential that the current potential that b is ordered becomes with a is ordered equates, the c current potential of ordering becomes earthing potential zero volt on the other hand, therefore, has produced the breakdown voltage V with reference diode 35 between the emitter of transistor 33 and base stage
ZCorresponding potential difference.Its result, because transistor 33 is in the ON position, stream has the electric current I of deciding in the electric current decision circuit 32, the electric current decision circuit 32 output igniting enabling signals that detect this electric current are given the igniting enabling signal terminal 10 in coil drive loop 8, make engine start.
Electric current decision circuit 32 can adopt various forms, and Fig. 5 and Fig. 6 are its examples.
Circuit shown in Fig. 5 has comprised 37,38 and 1 AND gates 39 of two comparators, distinguishes affix by resistance 40 and two assigned voltage V that reference diode forms at the positive terminal of comparator 37 and the negative terminal of comparator 38

3During scope, from the igniting enabling signal terminal 10 output igniting enabling signals of CPU44 to coil drive loop 8.
Even the 2nd embodiment according to this, by using the transistor 33 of nonlinear element, make and decide the electric current I generation, permit engine start with this, and aforementionedly decide electric current I and in fact must use regular ignition key that ignition switch is under the ON state could to measure, and be difficult to make engine start by the method beyond regular.In addition, judge, do not detect curtage over time in igniting permission, identical with the 1st embodiment in this, do not need the latch cicuit of high price, can cheap realization.
Bottom borrows Fig. 7 that the present invention the 3rd embodiment is described.
Among the 3rd embodiment, use nonlinear element to form the potential difference of regulation, when this potential difference is in predetermined scope, allow engine start.Ignition switch 3 includes two travelling contact F, G of mutual interlock start, and conducting between fixed contact J, K when the ON position simultaneously, cuts off between fixed contact H, I; And in the OFF position when (LOCK position), conducting between fixed contact H, I, simultaneously, fixed contact J, K are separated.And between fixed contact H, I, connecting the 1st reference diode 46 as nonlinear element.
When ignition switch 3 was in OFF position (LOCK position), the current potential that f is ordered equated to be 12V with cell voltage, and it is 0 that the current potential that g is ordered equals earthing potential, and therefore, the potential difference between f point and the g point becomes 12V.The output of window formula comparator 50 is set at low potential under aforementioned electric potential difference 12V, thus the motor fail to start.
Be in the ON position as ignition switch 3, the current potential that f is ordered is for deducting the breakdown voltage V of the 1st reference diode 46 from the 12V that equals cell voltage
