Description

[Detailed Description of the Invention] [Industrial field of application] The present invention has a function for charging a vehicle battery,
An indicator light device having a charging solar cell, which has a function of displaying the on / off state of the vehicle's electric equipment by visible light in order to prevent forgetting to turn off the electric equipment of the vehicle, and constitutes one independent device Is.

[Conventional technology]

Generally, vehicles such as vehicles and ships are equipped with a battery as a power source.

For example, a battery installed in a vehicle is charged by the engine and electric power is stored, but if the engine of the vehicle remains stopped for a long period of time, the electric power consumption by the electric devices installed in the vehicle is reduced. Even if it does not, the self-discharge of the battery will reduce the amount of electric power it has. When the power of the battery is reduced in this way, when starting the engine again, it may not be possible to supply the power enough to rotate the starter motor, and the engine may be unable to start.

For this reason, it is conceivable to use a solar cell that can generate power when exposed to sunlight, regardless of whether the engine is driven, and to charge the battery whose power has decreased due to self-discharge etc. at any time during the daytime. There is.

[Problems to be solved by the invention] In addition to the above case, the battery power decrease occurs due to driving the electric equipment system equipped in the vehicle with the engine stopped. In particular, the battery power will drop rapidly.

As described above, most of the reason why the electrical equipment system is driven even when the engine is stopped is that the electrical equipment is left off. For example, it is a common experience of us that we often forget to turn off the small lamps (side lights) of automobiles. As described above, if the electric equipment mounted on the vehicle is forgotten to be switched off while the engine is stopped, a large amount of electric power that cannot be supplemented by the charging solar cell will be consumed.

Therefore, it has already been proposed to inform the user by a buzzer that the user forgets to turn off the electrical equipment. However, it is structurally difficult to attach a buzzer for not forgetting to turn off the electrical equipment to an existing vehicle, for example, and it is limited to equipping the vehicle interior side, and the buzzer is retrofitted in this way. This is extremely expensive.

[Means for Solving the Problems]

In order to solve the above-mentioned problems, an indicator light device having a solar battery for charging according to the present invention is a charging device for charging a battery mounted in a vehicle in a main body case that is detachable from the vehicle. It is characterized in that it is provided with a solar battery for use and an indicator lamp for indicating an on / off state of electric equipment of the vehicle.

[Action]

According to the above configuration, it is possible to charge a battery whose electric power has decreased due to self-discharge or the like by the power generation of the charging solar cell. In addition, since a warning light is built in the same case as this charging solar cell, the warning light blinks or lights up to notify the driver etc. of the on / off state of electrical equipment equipped on vehicles such as vehicles and ships. It becomes possible. As a result, it is possible to avoid forgetting to turn off electrical equipment that consumes a large amount of electric power that cannot be supplemented by a charging solar cell.

Since the above-mentioned indicator light consumes extremely less power than a warning sound such as a buzzer, the power consumption of the battery can be suppressed as much as possible, and the on / off state of the electric equipment of the vehicle is displayed by visible light. It can be installed outside the passenger compartment. As a result, a solar cell for filling the battery is provided outside the passenger compartment where the sunlight is most easily received and the efficiency of light collection is high. It is possible to perform notification of forgetting to turn off the switch in the electric component device by one device. In addition, since the charging solar cell and the indicator light are built in the same independent case, as a power source of the indicator light, for example, it is possible to follow the same wiring route as the charging solar cell and connect to the battery, It will be possible to easily equip an existing vehicle with some modifications.
