Description

[Detailed Description of the Invention] This invention relates to an automatic operation stop device for a direction indicator light for a two-wheeled vehicle.

Turn on the motorcycle's turn signal switch manually.
It is common to cancel the contract.

The reason for this is that due to the structure of the vehicle body, it is impossible to follow the steering wheel operation like in a four-wheeled vehicle, and it is difficult to find a switch that operates reliably under favorable conditions. A switch device has been proposed that detects the distance traveled after the light switch is turned on and automatically releases the switch using electronic means, but this device is likely to be expensive due to its complicated circuit configuration.

This invention provides a relatively inexpensive device that is capable of reliably releasing the direction indicator light switch after the vehicle has traveled a certain distance after turning it on, and that is mainly based on a relay circuit.

Next, one embodiment of this invented device will be described.

In the figure, 1 and 2 are direction indicator lights, 3 is a turn signal relay, and both are electrically connected via relay contacts, which will be explained later.

That is, it has a relay coil 6,7 connected to the switching transistor 5 via a cancel switch 4 whose end is normally closed, and closing switches 8, 9 which are connected to the other end of the relay coil and which are normally open. The switching transistor 5 is connected to a power source F and a relay coil 6.
It forms a current supply circuit to 7.

The closing switch 8 is for turning on the direction indicator light 1, and the closing switch 9 is for turning on the direction indicator light 2.

6a and 6b are contacts that open and close by excitation of the relay coil 6, 6ct6d is a terminal of contact 6a, 6e,
6f is a terminal of contact 6b.

Also, the closing switch 9 is for turning on the direction indicator light 20 in the same way. A, 7b are contacts 7c, 7d are terminals of contact 1a, 7e,
7f is a terminal of contact 7b.

Therefore, when the closing switch 8 is turned on, the switching transistor 5 is turned on, the relay coil 6 is excited, and its contact 6a is switched from the terminal 6c to the terminal 6d. A flashing display appears on light 1.

On the other hand, as a result of switching the contact 6b from the open terminal 6e to the terminal 6f, a closed circuit is formed that leads to the terminal γC1 contact 7a and the direction indicator light 2, so that the relay coil 6 maintains the excited state even after the closing switch 8 is opened. and contact 6a.

The operation of the direction indicator light 1 is connected without the 6b returning to its original state.

In other words, the closing switch 8 is a self-resetting type.

In this case, the direction indicator light 2 is energized, but the current is small enough to maintain the excitation state of the relay coil 6, so it does not turn on.

Note that the above-mentioned effect is the same even when the closing switch 9 is turned on, and the displaying effect of the direction indicator light 2 is obtained, and this effect continues even after the closing switch 9 is released.

The above operation has been described for the case where the turn-on switch is turned on to obtain the operation of the direction indicator lamp.Next, the means for automatically stopping this operation will be explained.

That is, this automatic stop means includes a mileage detecting device 10 that detects the mileage of the vehicle after the closing switch is turned on, and a mechanism that stops driving the mileage detecting device 10 when the closing switch is in an open state. The main components are a discriminating transistor 11 which acts, and an operation circuit 12 which receives a signal from the mileage detecting device 10 and acts to lead the switching transistor 5 to the OFF state.

The mileage detection device 10 includes an on-off switch 10a that opens and closes only when the vehicle is running and generates an intermittent current, a capacitor 10b and resistors 10c, 1 that convert this intermittent current into pulses.
0c, a rectifying diode 10d, and a capacitor 10e charged by a pulse current.

The open/close switch 10a is a switch that opens and closes in response to the rotation of a speedometer cable, for example, and is always open and closed to generate an intermittent current while the vehicle is running.

The intermittent current is converted into a pulse by a resistor 10c and a capacitor 10b, and then acts to charge a capacitor 10e.

The capacitor 10e is charged by a pulse current, and functions to drive the operating circuit 12 when the terminal voltage reaches a predetermined value.

Note that this terminal voltage is proportional to the opening/closing speed of the on-off switch 10a, that is, the speed of the vehicle, and will rise rapidly if the speed is high. Since it is determined by the number of pulses generated by the vehicle, the set voltage will be reached after traveling a certain distance regardless of the traveling speed.

As mentioned above, after traveling a certain distance, the capacitor 10e
When the terminal voltage reaches a certain value, this voltage is detected and the operating circuit 12 is driven, so that the operating circuit 12 is driven after the vehicle has traveled a certain distance after turning on the closing switch. become.

The discrimination transistor 11 is in an on state before the closing switch is turned on, and functions to cut off charging to the capacitor 10e and maintain an off state after the closing switch is turned on so that the capacitor 10e is charged. do.

This means that the base terminal of the transistor 110 is a diode D,
This is because since it is connected to the power supply side terminals of the closing switches 8 and 9 through D, it is grounded through this while the direction indicator lamp 1 or 2 is in operation, and the base current flowing through the resistor R is cut off.

Note that the base current when the direction indicator light 1 is operating is the terminal 6f-
The path from contact 6b to terminal 7C to contact 7a and one-way indicator light 2 is grounded.

When the direction indicator light 1 is not operating, the contact 6b is open, so the transistor 11 operates normally and the capacitor 1
This will prevent charging of 0e.

In this embodiment, the operating circuit 12 is composed of a voltage comparator, and when the terminal voltage of the capacitor 10e reaches a set value, the logic level of its output switches from L' to H'', turning off the switching transistor 5. It works to make things happen.

Note that the output of the operating circuit 12 is always at the L level, and the switching transistor 5 is set to turn on immediately when the closing switch is turned on.

In the above configuration, if the closing switch 8 is turned on while driving, the switching transistor 5 is turned on, and the relay coil 6 is energized, and the contact 5a is turned on.

6b are switched to the terminals 6d and 6f, respectively.

This allows turn signal relay 3 to be connected to direction indicator light 1.
An intermittent current flows and a blinking display starts.

In this case, even if the closing switch 8 is opened, a closed circuit leading to the direction indicator light 2 is formed through the terminal 6f - the contact 6b, the terminal γC - the contact 7a, and the excitation current of the relay coil 6 flows, so that the contacts 6 a t 6 b There will be no return.

As a result of the prescription determination transistor 11 being turned off, a pulse current generated by the on/off switch 10a flows through the capacitor 10e, and charging is started.

When this terminal voltage reaches a predetermined value, that is, the vehicle travels a certain distance after turning on the closing switch 8, the output of the operating circuit 12 switches to the H level, which turns off the switching transistor 5.

As a result, the power to the relay coil 6 is cut off at the contact 6at6.
b is restored and the operation of the direction indicator light 1 is stopped.

In this case, even if the vehicle stops at a congested road or at an intersection, it will not be released until the vehicle has traveled a certain distance, so the direction indicator lights may stop working before the necessary driving operation is completed. There is no inconvenience.

Further, if an operation such as turning left immediately after turning right is required, the cancel switch 4 can be turned off, and normal operation can be obtained by turning on the necessary closing switch afterwards.

FIG. 2 shows another embodiment of the operating circuit 12, which is composed of transistors 13 and 14.

a and b of the operating circuit 12 in FIG. Terminals a and b of transistors 13 and 14 are respectively connected to the 0 section.

When C is connected, when the capacitor 10e rises to a predetermined terminal voltage, the transistor 13 is turned on, leading the transistor 14 to be turned off, and as a result, the switching transistor 5 is turned off, and the operation of the direction indicator lamp is stopped in the same way as described above. be able to.

Note that before the closing switch is turned on, the transistor 13 is in an off state, so the transistor 14 is in a state where it can be turned on, and as soon as the closing switch is turned on, it is immediately turned on and the normal operation of the direction indicator light is obtained.

As is clear from the above explanation, this device allows the turn signal lights to operate when the switch is turned on, and this operation is automatically canceled after driving a certain distance.
This eliminates the difficulty of driving with the turn signal lights on, which is extremely advantageous for safe driving.

In particular, since the turn signal switch is released based on the distance traveled after turning it on, it will operate regardless of actions such as stopping the vehicle due to road congestion, and will not turn on when changing roads or changing direction. There is no inconvenience such as being canceled at any time.

Furthermore, even if you want to cancel halfway through the set distance, you can do this manually.
For example, it can sufficiently handle cases such as turning right or left over extremely short distances, and can be expected to have effects not found in conventional products.

In addition, the energization of the direction indicator lamps is carried out through the contacts of the relay coil, which is excited when the closing switch is turned on, and even after the closing switch is turned off, the relay coil is connected to the contacts of the relay coil and the lights that are not lit. Since the configuration is such that the excitation state is maintained through the contacts of the relay coil, the closing switch 8 may be of a self-resetting type.

This has the effect of significantly simplifying the configuration compared to a closing switch that requires a self-holding circuit, such as that disclosed in Japanese Patent Publication No. 49-40119, for example.
