Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an emergency starter device for a magnetic generator that temporarily starts and operates the engine when the engine cannot be started due to a dead battery.

Conventional generators use a full-wave rectifier to rectify the AC output of a magnetic generator directly connected to the engine's crankshaft, converting it into DC output to charge the battery, and at the same time supplying DC output to the ignition coil, lamp load, etc. ing.

However, with the conventional system described above, if the battery is discharged too much and the battery is dead, even if you try to start the engine with a kick, the rotation speed of the magnetic generator due to the kick is low, so the output of the generator is small and its output is low. The battery takes up most of the engine's power, making it impossible to start the engine.In particular, if the battery is poorly maintained, this can quickly lead to problems starting the engine, making the engine unusable, which is a serious drawback.

In order to eliminate the above-mentioned drawbacks, the present invention removes the battery connected in parallel with the ignition coil from the circuit by switching a switch, operates the ignition coil with the DC output of a pulsating full-wave rectifier, and uses a magnetic generator. Is it possible to charge a discharged battery by half-wave rectifying the AC output with another rectifier? When Hibiki is removed from the ignition coil, the engine can be started, and at the same time, the battery can be charged in a separate circuit, so even if the battery is dead, the engine can be started with an emergency start, and the battery can be easily returned to normal condition. The purpose of this dispute is to provide an emergency starter for magnetic generators that can be used as an emergency starter for magnetic generators.

The present invention will be described below with reference to embodiments shown in the drawings.

First, the first embodiment shown in FIG. 1 will be explained.
A is a magnetic generator 1 that is used only when the circuit is turned on at night.
1b is used for both daytime and nighttime circuits. 2a and 2b are day and nighttime coils used for both daytime and nighttime circuits. 2a and 2b are daytime and nighttime circuit changeover switches that work in conjunction with each other, and switch 2a is ON. When switch 2b is also ON, switch 2a is
When is OFF, switch 2b is also OFF.

3a is a single-phase full-wave rectifier consisting of a diode 3a 1.3a2.3a3.3a4, 4 is a high-voltage secondary voltage generated by the ignition coil, which is supplied to an ignition plug, and 7 generates a spark to ignite the mixture in the engine. .

5 is a cam and a breaker that interrupts the primary current of the ignition coil 4; 6 is a capacitor that extinguishes the point arc of the breaker; 8 is a battery; 9a, 9b, and 9c are lamp loads such as headlamps, tail lamps, and meter lamps; 3b
is a half-wave rectifier made of diodes, 2c is the two contacts 2
This is an emergency start changeover switch having c1.2c2.

Next, the operation of the device of the present invention having the above structure will be explained.

Under normal conditions, the emergency start selector switch 2c is closed to the contact 2c2 side.

Also, during the daytime, the day/night selector switches 2a and 2b are OFF.
The AC output of the day/night coil 1b is transferred to the full-wave rectifier 3a.
It becomes a DC output and is supplied to the ignition coil 4 at the same time as charging the battery 8.

At night, the day/night selector switches 2a and 2bij are turned on, and both coils 1a and 1b are connected in parallel, resulting in both AC outputs or fully rectified 'f53a', which then becomes DC output, which powers the battery 8, ignition 4, and lamp load. 9a, 9
b, supplied to 9c.

Further, in the case of emergency starting, the emergency starting switch 2c is turned on to the contact 2c1 side.

As a result, the battery 8 is opened from the side of the rectifier 53a and connected to the side of the half-wave rectifier WBb, and at this time, the breaker 5 is connected to the coils 1a and 1b when the output on the 1X side of the coil 1a11b is positive. The primary current of the ignition coil 4 is cut off when a charging current is not flowing, and the entire output of the generator 1 is supplied to the ignition coil 4 side, increasing the secondary voltage of the ignition coil 4, and the engine to ensure that it can start.

When this emergency start is performed during the daytime +5, the output of the day/night coil -b is supplied to the ignition coil 4 via the full-wave rectifiers 3 and 1; the output of the night-time coil 1a is supplied to the battery via the half-wave rectifier 3b. Charge 8.

Also, at night, when the output on the □ 1X side of both coils la and 1b is positive, the output is supplied to the ignition coil 4 and lamp load via the full-wave rectifier 53a to operate the ignition coil 4, and both coils 1? , lb whose 1Y side outputs are positive, the output is supplied to the ignition coil 4 and lamp load via the full-wave rectifier 3a from the sigure coils Ia and 1b, and at the same time, the battery 8 is also charged via the half-wave rectifier @3b.

FIG. 2 shows a second embodiment of the present invention. In order to further increase the output supplied to the ignition coil 4 compared to the first embodiment, a switch 2d that interlocks with the emergency start changeover switch 2c is provided. 2c to the contact 2c1 side, the switch 2d is turned OFF and the lamp load is removed from the load of the magnetic generator 1, so that both coils Ia,
The entire output of 1b is supplied to the ignition coil 4,
Emergency starting can be made easier.

Furthermore, even when a three-phase magnetic generator is used, the same effects as in each of the above embodiments can be obtained by connecting a half-wave rectifier to one of the three output terminals.

As described above, according to the present invention, even if the battery is discharged, the battery is removed from the circuit on the full-wave rectifier side and charged with another half-wave rectifier, so the ignition coil is connected to the DC output of the pulsating full-wave rectifier. When activated, it is possible to reliably start the engine in an emergency without being affected by the discharged battery, and at the same time, it has the excellent effect of being able to charge the battery via a half-wave rectifier and return it to normal condition. .

Furthermore, since the connection of the ignition coil does not change even during an emergency start, even if the circuit is switched to a steady state after the engine has been started during an emergency start, this switching operation will generate an ignition spark at an unnecessary time. This has an excellent effect in that problems such as ignition sparks not being generated during the switching period do not occur at all.

And ζ When a half-wave output with the opposite polarity to the half-wave rectifier 1 is generated in the night-only coil and the day-and-night coil, the ignition intermittent means (breaker) is cut off. While charging an over-discharged battery, it is possible to improve spark performance by sufficiently supplying the generated output from both the night-only coil and the day-and-night coil for ignition without being affected by this battery charging. This has an excellent effect.
