BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a starting device for a batteryless vehicle.

[0002]

BACKGROUND OF THE INVENTION motorcycles, etc. Conventionally, a battery and IG two Tsu Deployment switch and star motor and the starter button, the starter relay is activated by pressing the starter button, the engine start by the rotational force of the starter motor This is generally done, and there is also one in which an electric circuit system for automatically turning on a light is incorporated in the electric circuit system for starting the engine. That is, there is one in which a capacitor charged directly while the starter button is pressed in order to perform automatic lighting of the light by operating the light relay is directly connected to the light relay. (As a prior art document, there is Japanese Utility Model Laid-Open No. 60-108548).

By the way, in recent years, the number of motorcycles for which the mounting of a battery has been abolished in order to reduce the weight of vehicles has been increasing mainly in small displacement vehicles. Most of the battery-less vehicles use a CDI (capacitive discharge type igniter) as an ignition device. However, in order to improve and stabilize the ignition performance, a conventional ignition high voltage coil is used. The number of models that have been abolished and have adopted DC-CDI that uses the output of the low-voltage coil for lamps as a power source tends to increase.

However, when the DC-CDI is used in a battery-less vehicle, the ignition power source and the lamp power source are shared, so that when a large lamp load is connected, ignition occurs in the low rotation range at the kick start. The device may not be able to supply sufficient power and may be difficult to start. Such a situation may occur especially in a vehicle in which the lights are automatically turned on and it is not possible to turn off the lights.

[0005]

SUMMARY OF THE INVENTION Therefore, the present invention is intended to provide a batteryless vehicle starter capable of supplying sufficient electric power to the ignition device in the low rotation range at the kick start.

[0006]

SUMMARY OF THE INVENTION A batteryless vehicle starting device of the present invention for solving the above problems is an ignition device that operates in a vehicle without a battery and with a DC power source obtained from a lamp load generator. in the starting device for a vehicle having, disconnected at the lamp load from the time of kick starting the DC power supply
Output from the ignition device after the ignition device is activated
A control circuit for connecting a DC power supply and a lamp load by a signal is provided between the DC power supply and the lamp load.

[0007]

In the batteryless vehicle starter of the present invention constructed as described above, since the lamp load is disconnected from the DC power supply by the control circuit during kick start, no electric power is supplied to the lamp load and the ignition device is ignited. Enough power is supplied to
It When the ignition device starts operating, the ignition is synchronized with it.
A signal voltage is output from the device to the control circuit, the control circuit connects the DC power supply and the lamp load, and power is supplied to the lamp load to light the lamp. Ignition device
After operation, that is, after the engine starts, the DC power supply and the lamp

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Various embodiments of a batteryless vehicle starting device of the present invention will be described with reference to the drawings. The embodiment shown in FIG.
DC power supply 2 and lamp obtained from lamp load generator 1
The transistor 9 is installed in the circuit with the load 3
Connect the output signal line 11 of the ignition device 4 to the base of the resistor 9.
It was done.

[0009] In the embodiment shown in FIG. 1, the ignition device 4 is used.
After moving, the output signal line 11 to the base of the transistor 9
A signal voltage is output to the kick start
While the ignition device 4 at the beginning of the time is not operating,
Lamp load 3 from DC power source 2
It is in a disconnected state. Therefore, when kicking
In the initial stage, sufficient power is supplied to the ignition device 4, so
The engine starts smoothly. Ignition device 4 starts operation
After the engine is started, that is, after the engine is started,
The signal voltage is sent to the transistor 9 and the DC power supply 2 and run
The load 3 is connected by the transistor 9 and the lamp load
Power is supplied to 3 and the lamp is turned on.

[0010] The embodiment shown in FIG. 2 performs kick start,
Output after engine starts, that is, ignition device 4 operates
A signal voltage is output from the signal line 11 to the base of the transistor 7.
Is applied, the relay 5 is activated, and the generator 1 for lamp load
The obtained DC power source 2 and lamp load 3 are switched by the switch 6.
Are connected again, power is supplied to the lamp load 3,
Is lit up. Therefore, kick start
Power is not supplied to the lamp load 3 in the
4 is supplied with sufficient power, and thus the embodiment shown in FIG.
The same effect as can be expected.

[0011] The embodiment shown in FIG. 3 is a generator for a lamp load.
In the circuit of DC power supply 2 and lamp load 3 obtained from 1.
A relay 5 is provided, and the output signal of the ignition device 4 is provided to this relay 5.
The line 11 is connected.

[0012] In the embodiment shown in FIG. 3, the ignition device 4 is used.
After moving, the signal voltage is output from the output signal line 11 to the relay 5.
It is designed to be used in the initial ignition
Relay 5 does not work while device 4 is not working
The lamp load is disconnected from the DC power supply 2.
ing. For this reason, the ignition device 4 is set at the beginning of kick start.
Since sufficient power is supplied, the engine can start smoothly.
Will be After the ignition device 4 starts to operate, that is, the engine
After the ignition is started, the signal voltage of the ignition device 4 is applied to the relay 5.
