Description

[Detailed description of the invention] This invention is a starting safety circuit for vehicles that is equipped with a starting safety circuit that operates when the engine is started to control the ignition system, and can switch the engine operating state between starting mode and running mode. Regarding equipment.

Conventionally, in the case of vehicles such as motorcycles equipped with an automatic clutch, the operating state of the engine can be switched between a starting mode and a running mode, and the engine can be started only in the starting mode, and the engine can be ignited at the time of starting. Some starting safety devices that control the timing and prevent the vehicle from jumping out suddenly have already been implemented. However, with such conventional starting safety devices, when restarting the engine after it has stopped (so-called engine stalling), (1) switches from drive mode to starting mode, (2) performs the starting operation, and ( 3) A complicated three-step operation is required to switch to driving mode, and if the engine stalls at an intersection, especially if the rider is a beginner, he or she may be in a hurry and not be able to start the engine. .

The present invention was made to eliminate such conventional drawbacks, and is a vehicle starting system that automatically returns from driving mode to starting mode when the engine stops, making it easier to operate. The purpose is to provide safety equipment.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings. First, in FIG. 1, this starting safety device for a motorcycle includes a starting mode holding circuit 1 and a running mode holding circuit 2.
is selectively switched depending on the operating state of the motorcycle's engine. That is, when the engine of the motorcycle stops, or when the starting mode switch 3 is pressed even with the engine running, the starting mode circuit 1 is activated.
When the driving mode switch 4 is pressed after starting the engine, the driving mode holding circuit 2 is activated.

The starting mode circuit 1 includes a battery 5, a main switch 6, a first relay switch 7 as a first switch, a starting mode display lamp 8, and a starting safety circuit 9 connected in this order to form a closed circuit. A series circuit consisting of a starter button 10 and a starter motor 11 is connected in parallel to a series circuit consisting of a starting mode indicator lamp 8 and a starting safety circuit 9. When activated, the starting safety circuit 9 outputs a control signal that delays or widens the ignition timing to control the engine's ignition to a low output state, thereby preventing the motorcycle from suddenly jumping out. Ru.

The driving mode holding circuit 2 includes a power supply circuit 12, a driving mode display lamp 13, a relay coil 14 as a drive circuit, a second relay switch 15 as a second switch, and a third relay switch 16 in this order. They are connected to form a closed circuit. A running mode switch 4 is connected in parallel to a series circuit consisting of a power supply circuit 12, a running mode display lamp 13, and a relay coil 14. Further, a series circuit consisting of a relay coil 17 and a starting mode switch 3 is connected between both ends of the power supply circuit 12, and the relay coil 17, third relay switch 16, and starting mode switch 3 constitute a starting mode switch circuit 18. do. The power supply circuit 12 consists of a generator, a rectifier, a smoothing circuit, etc. driven by the engine, and supplies power only when the engine is started.

The first relay switch 7 is urged toward the closing side by a spring (not shown), and the second relay switch 15 is urged toward the opening side by a spring (not shown). The relay coil 14 is connected to the first and second relay coils 7,
When the relay coil 14 is energized, the first relay switch 7 is opened and the second relay switch 15 is closed. Further, the third relay switch 16 is biased toward the closing side by a spring (not shown), and the relay coil 17 is energized when the third relay switch 16 is biased toward the closing side.
Open 6.

The running mode switch 4 and the starting mode switch 3 are normally open contacts that become conductive only when pressed, and are configured as shown in FIG. 2, for example. That is, an operating piece 20 made of a non-conductive material and rotatably supported by a support shaft 19 is biased by a pair of springs 21 and 22 to maintain its neutral position, and one side of the operating piece 20 is A contact 23 provided and a contact 24 fixed opposite to the contact 23
The driving mode switch 4 is constituted by the driving mode switch 4, and the starting mode switch 3 is constituted by a contact 25 provided on the other side of the operating piece 20 and a contact 26 fixed opposite to the contact 25. Therefore, operation piece 2
Only when one side of the 0 is pressed, either the running mode switch 4 or the starting mode switch 3 becomes conductive, and when the operating piece 20 is released, the operating piece 20 releases the springs 21, 22. The air is restored to the neutral position by the spring force, and both switches 3 and 4 are shut off.

Such an operation piece 20 is displayed, for example, as shown in FIG. 3. That is, "driving" is displayed on the upper surface of the operation piece 20 on the driving mode switch 4 side. Furthermore, since the pressing operation of the starting mode switch 3 is only necessary when the motorcycle is placed on its stand with the engine running and the rider leaves the motorcycle, there is a "temporary" button on the top surface of the operating piece 20 on the side of the starting mode switch 3. "Stopped" is displayed. Moreover, in the portion of the operation piece 20 corresponding to each switch 4, 3, there is a driving mode display lamp 13 for displaying which mode the switch is currently in.
and a starting mode indicator lamp 8 are built-in.

Next, the operation of this embodiment will be explained. First, when driving the motorcycle, the main switch 6 is turned on, and then the starter button 10 is pressed. At this time, when the engine is not started, the relay coil 14 is not excited,
Therefore, the first relay switch 7 is conductive, and when the main switch 6 is conductive, the starting mode display lamp 8 lights up and the starting safety circuit 9 is activated. Therefore, starting the engine by pressing the starter button 10 is performed under the control of the ignition system by the starting safety circuit 9, thereby preventing the motorcycle from suddenly jumping out.

After starting the motorcycle, when the driving mode switch 4 is pressed as shown in Fig. 4, the power supply circuit 1
The current from 2 flows through the running mode display lamp 13 to the relay coil 14, the running mode display lamp 13 lights up, and the relay coil 14 is excited. Therefore, the first relay switch 7 is cut off and the second relay switch 15 is made conductive. Furthermore, at this time, the relay coil 17 is demagnetized and the third relay switch 16 remains conductive, so even if the driving mode switch 4 is cut off, the relay coil 14 remains energized and the driving mode is maintained. Ru.

Next, let's assume that the engine stops at an intersection or the like, a so-called engine stall. In this case,
When the engine is stopped, power supply from the power supply circuit 12 is stopped. Therefore, the relay coil 14
is demagnetized, the first relay switch 7 becomes conductive, and the second relay switch 15 is cut off, as shown in FIG. Because of this, the starting safety circuit 9 has a battery.
After the engine stalls, the starter button 10 can be pressed immediately to start the motorcycle, allowing the motorcycle to be restarted safely.

Furthermore, it is assumed that the motorcycle is temporarily stopped with the engine running, the stand is erected, and the rider leaves the motorcycle. In this case, as shown in FIG. 6, it is sufficient to press the starting mode switch 3 to make it conductive. As a result, the relay coil 17 is energized and the third relay switch 16 is cut off. Therefore, the relay coil 14 is demagnetized, the first relay switch 7 is made conductive, the starting safety circuit 9 is activated, and the motorcycle is prevented from jumping out.

FIG. 7 shows another embodiment of the present invention, in which a slide piece 27 made of a non-conductive material is urged to maintain its central position by a pair of springs 28, 29, and one of the slide pieces 27 is biased to maintain its central position. A contact 23 provided on the side of the slide piece 27 and a contact 24 fixed opposite to the contact 23 constitute the travel mode switch 4, and a contact 25 provided on the other side of the slide piece 27 and the contact 24 fixed opposite to the contact 23 constitute the travel mode switch 4. A starting mode switch 3 is constituted by a contact 26 fixed opposite to the contact 25. Therefore, only when the slide piece 27 is slid to either side, either the running mode switch 4 or the starting mode switch 3 becomes conductive, and when the slide piece 27 is released, either switch 3 is turned on. , 4 are also blocked.

In the above embodiment, the starting mode switch 3 is a normally open contact, which becomes conductive only when pressed, but it may also be a normally closed contact. In that case, the starting mode switch circuit 18 is omitted and the normally closed contact is turned on. The starting mode switch 3 may be inserted between the second relay switch 15 and the power supply circuit 12.

FIGS. 8 and 9 show still another embodiment of the present invention, in which a starting mode switch 3 is arranged to be interlocked with a stand 30 of a motorcycle. That is, since the starting mode switch 3 needs to be operated only when the motorcycle is temporarily stopped with the engine running and the stand 30 is erected, it is necessary to operate the starting mode switch 3 rather than manually operating the starting mode switch 3. The operation will be easier if the start switch 3 is automatically operated in conjunction with the action of raising the stand 30.

That is, the stand 30 is attached to the support plate 32 provided on the frame 31 of the motorcycle via the shaft 33.
is rotatably supported, and this stand 30
A starting mode switch 3 is supported by the frame 31 so as to be activated when the switch is upright. stand 3
0 is provided with a raised pressing portion 34 that comes into contact with and activates the actuator 3a of the starting mode switch 3 when the motorcycle is rotated to a state where it can support the motorcycle. Part 3
4 is formed so as to come into contact with the actuator 3a only when the stand 30 is erected.

According to this embodiment, the starting mode switch 3
is automatically activated when the stand 30 of the motorcycle is erected, and the effort of operating the starting mode switch 3 can be omitted, making the switching operation easier.

As shown in each of the above embodiments, the starting mode circuit 1 is activated when the engine is started, so the headlights of the motorcycle can always be set to low beam when starting, and the warning system can only be used when starting. It is also easily possible to perform necessary display.

As described above, according to the present invention, the battery, the first switch, and the starting safety circuit for controlling the ignition of the engine to a low output state form a closed circuit to constitute the starting mode circuit, and the starting mode circuit is configured to drive the engine. a power supply circuit that can supply power only at certain times; a drive circuit that opens the first switch when energized by the power supply circuit; and a second switch that closes the first switch when the drive circuit is energized.
A drive mode holding circuit is formed by forming a closed circuit with the switch, and a drive mode switch that closes only when pressed is connected in parallel to the drive circuit and the power supply circuit, and a second switch of the drive mode holding circuit is connected in parallel with the drive circuit and the power supply circuit. A starting mode switch circuit that can temporarily cut off the running mode holding circuit is inserted between the power supply circuit and the power supply circuit, so that when the engine stops,
The starting mode circuit is always ready to operate, eliminating the need for complicated switching operations and facilitating the starting operation. Furthermore, by operating the starting mode switch circuit even when the engine is temporarily stopped and left with the engine running, the starting safety circuit can be activated and the vehicle can be prevented from flying out.
