Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention is a turn signal indicator for a driver of a light vehicle such as a bicycle to indicate the intention of turning at an intersection or the like to another vehicle or the like.

[0002]

[Prior art]

 Conventionally, a light vehicle such as a bicycle does not have a direction indicator for indicating the direction of turning at an intersection or the like to other vehicles. Publicly, they are instructed to show their intentions by keeping their right arm away from the steering wheel and extending it horizontally or bending their elbows upward at a right angle. It is driving and very dangerous. Also, the reality is that few people are doing this. When a bicycle is viewed by a driver of a motor vehicle such as an automobile, the course of the bicycle is unknown, which may cause an unexpected accident.

It has been common practice to use a light bulb for a direction indicator of an automobile or the like, but power consumption is reduced in a light vehicle such as a bicycle which cannot be equipped with a large capacity battery or a dynamo. It is not suitable to use a large light bulb. Another problem is that the dynamo that is generally used for bicycle headlights requires a large driving force to generate power, and as a result, the pedal becomes heavy and the user cannot use it easily.

[0004]

[Problems to be solved by the present invention]

 The present invention realizes a turn signal indicator for mounting on a light vehicle without a prime mover such as a bicycle, which can be driven with low power consumption without annoying a user because a dynamo is not used. Will contribute to traffic safety.

[0005]

[Means for Solving the Problems]

 The bicycle turn indicator of the present invention uses a high-intensity light emitting diode instead of a light bulb to drive the bicycle with low power consumption. It should be noted that the system is equipped with a power supply unit that uses both a solar battery and a storage battery so that the troublesome battery replacement work can be eliminated.

One of the weak points of the light emitting diode is low brightness. Further, in order to increase the brightness by using the high brightness light emitting diode, it is necessary to increase the current value, but if the current value is increased, the power consumption increases and the consumption of the battery is promoted. Whether or not the light emitting source looks bright depends on the illuminance around the light emitting source. In the case of a direction indicator, light may be bright during the day and dark at night. In order to solve this problem, the present invention utilizes a solar cell, and in the daytime, the solar cell applies a high voltage to the light emitting diode to emit light with high brightness, and at night, the power is supplied from a storage battery to suppress the brightness and emit light. It is a thing. The solar cell is also used for charging the storage battery during the daytime.

The configuration will be described below with reference to the drawings.

FIG. 1 is a block diagram of the present invention. The 1st switch works in conjunction with the 2nd switch, and the 2nd switch will be closed when the 1st switch is tilted to the right or left. Only when the 1st switch is in the center. Switch 2 is open. When the switch of 1 is tilted to the right, the control unit of 5 controls so that the light emitting diodes of 3 and 4 mounted on the right side of the vehicle will blink. Similarly, the switch of 1 is tilted to the left. Then, the control unit 5 controls so that the light emitting diodes 6 and 7 mounted on the left side of the vehicle blink. Here, 3 and 6 are light emitting diodes that emit light toward the front of the vehicle, and 4 and 7 are light emitting diodes that emit light toward the rear of the vehicle. In addition, in order to prevent forgetting to turn off this device, some sound is emitted from the 8 speakers during operation.

Reference numeral 9 denotes a storage battery of this device, which is a main power source. Reference numeral 10 denotes a solar cell of this device, which is used for charging the storage battery 9 and a driving power source of this device in the daytime. The solar cell of 10 does not exhibit the ability to charge the storage battery of 9 unless the voltage of the storage battery of 9 is higher. The diode 11 is for preventing current from flowing backward from the storage battery 9 to the solar cell 10 at night. The dropper 12 is a circuit for ensuring that the voltage applied to the point A is constant at any value, and the control unit should always drive at a constant voltage regardless of day or night. You can

On the other hand, the light emitting diodes 3, 4, 6 and 7 are subjected to a high voltage by the solar cell 10 at the daytime and a low voltage by the storage battery 9 at the nighttime. Assuming now that the voltage of the solar cell of 10 is twice the voltage of the storage battery of 9, the daytime voltage at point A is twice the voltage at night and the resistance of 13 is constant, so According to the law, the current flowing through each light emitting diode is twice as much in the daytime as it is at night. As a result, the brightness of each light emitting diode becomes higher in the daytime than in the nighttime, which realizes a power-saving and easy-to-see direction indicator regardless of the surrounding illuminance.

[Action]

 By mounting the bicycle-mounted turn signal indicator of the present invention on a light vehicle such as a bicycle that does not have a prime mover, it is possible to indicate the course direction to other vehicles and pedestrians. Accidents related to light vehicles are reduced and safe traffic is secured.

[0012]

【Example】

 An embodiment will be described below with reference to the drawings. FIG. 2 is a top view of an example in which the bicycle-mounted turn indicator of the present invention is mounted on 14 bicycles. Reference numeral 15 is a case in which the main body of the control unit of the apparatus is housed, excluding the switches 1 and 2, and the light emitting diodes 3, 4, 6 and 7.

FIG. 3 is a diagram showing 14 bicycles equipped with the bicycle-mounted turn indicator of the present invention, which is stopping from trying to turn right from a narrow road to a wide road.

Conventionally, the driver of a car traveling straight on 16 wide roads did not know whether 14 bicycles were about to make a right turn or a left turn. If 14 bicycles make a left turn, you don't need to pay much attention, but if you make a right turn, you may come out in front of your car and you have to be very careful. Now, 14 bicycles have activated the bicycle-mounted turn signal indicator of the present invention to indicate that they are willing to make a right turn, so 16 motorists can definitely pay the utmost attention. This can prevent such a case collision.

[0015]

[Effect of device]

 If the bicycle-mounted turn indicator of the present invention is mounted on all light vehicles that do not have a prime mover such as a bicycle, the intention of indicating the course direction of the bicycle or other vehicle to other vehicles or pedestrians can be indicated. This will reduce accidents and secure extremely safe traffic.
