Description

[Detailed description of the invention] <Industrial field of application> The invention provides a fender pole with a light-emitting function to prevent accidental contact with the side part of the fender of an automobile, etc., on the main body of a solar cell module in which a solar cell for battery charging is installed. This invention relates to improvements to solar cell modules installed in vehicles.

<Prior Art> The fender side of a car has extremely poor visibility from the driver's seat, and is one of the areas where collisions due to driving errors are likely to occur. Therefore, in order to prevent this fender side contact accident,
For example, an elastic support called a side pole is established near the left front edge of a car, and if necessary, a light emitting function is added to this side pole as a guideline for measuring the distance between the fender side and the opposing object when driving. It was. In addition, the side poles emit light by connecting them to small vehicle lamps.

On the other hand, the power source for small lamps and the like is provided by a battery built into the vehicle, and this battery is charged by a generator that operates in conjunction with the engine. In the case of a side pole having a light emitting function, the power for light emission of this side pole is also obtained from the battery. When the side pole emits light, the distance to the opposing object can be easily recognized by the change in the light irradiation shadow reflected on the opposing object.

The battery is charged by the generator mentioned above,
Since there is no power generation capacity during the engine stop period, the capacity of the battery decreases due to self-discharge of the battery and the like. Therefore, in order to prevent this capacity reduction, a solar cell module for a vehicle having a solar cell installed therein is mounted on the vehicle body, and a battery is charged by the electromotive force of the solar cell.

<Problems to be solved by the invention> When installing side poles to prevent collisions on the side of the fender, in order to more completely prevent collisions, it is necessary to provide the side poles with a light-emitting function so that they can be used at night, etc. However, it is desirable that the configuration be such that the distance from the opposing object can be easily determined. However, in order to make the side pole emit light, wiring with an electrical system is required, but finding this wiring and wiring terminals is extremely difficult for the user and requires complicated work.

<Means for Solving the Problems> In view of the above-mentioned circumstances, the present invention utilizes a solar cell module for battery charging, attaches a side pole with a light emitting function to this main body, and further includes a light emitting body for the battery and side pole. An illuminance detection circuit that detects daytime and nighttime, a power generation signal detection circuit that detects the waveform of the generator's power generation, and a control circuit that causes the light emitter to emit light only at night and while the engine is running are interposed between the vehicle solar system and the vehicle solar system. By integrating it as a battery module, it forms a solar battery module that prevents contact accidents on the fender side and has a battery charging function.

<Operation> According to the configuration of the present invention, the solar cell module can be mounted near the fender side of the vehicle using magnets, screws, or other means, and the lead wire drawn out from the module body can be electrically connected to the battery terminal. Wiring is complete and installation is extremely easy. The side poles illuminate only at night when the engine is running, illuminating the area around the fender. Therefore, collision accidents near the fender side can be easily prevented. Also, during the daytime, the batteries are charged by solar cells.

<Embodiment> FIG. 1 is a block diagram of a solar cell module for a vehicle to explain one embodiment of the present invention. FIG. 2 is a plan view of the main body of the solar cell module for a vehicle.
FIG. 3 is a block diagram showing the circuit functions of a solar cell module for a vehicle.

Solar cells 1 arranged in parallel within the main body are embedded in transparent acrylic resin 2. Further, a translucent side pole 3 is established near the top of the main body, and a light emitting diode 4 is arranged at the bottom of the side pole 3. The light from the light emitting diode 4 is guided into the side pole 3 and
is derived from the surrounding surface of A frame 5 is formed around the peripheral edge of the main body from non-transparent acrylic, plastic, Bakelite, or other resin, and the inner surface of the frame 5 presents a light-reflective interface. A metal fitting 6 and screws 7 are provided on the lower surface of the main body for attachment to the vehicle body. Instead of the screws 7, a magnet, adhesive, or the like may be used for attachment. The electrodes of the solar cell 1 are connected to a vehicle battery 15 via lead wires 8. Further, the light emitting diode 4 and the battery 15 are also electrically connected via the lead wire 8. A fuse 9 is interposed in the middle of the lead wire 8, and a crimp terminal 10 for connection to a battery terminal is attached to the end.

The electromotive force of the solar cell 1 is generated by the backflow prevention diode 1.
The battery 15 is charged by the lead wire 8 through the lead wire 8. Further, this electromotive force is input as an electromotive force signal to an illuminance detection circuit 14 that detects the presence or absence and distinguishes between day and night. Note that the illuminance detection circuit 14 may be configured to determine day and night by providing an optical sensor near the solar cell 1 and directly detecting brightness. The accumulated power from the battery 15 is supplied to the control circuit 12 via the fuse 9 and the lead wire 8, and when charging is performed from the generator linked to the engine drive, the power generation waveform superimposed on the supplied power is the power generation waveform. The signal is input to the detection circuit 13. Control circuit 12
The electric power of the battery 15, which is controlled on and off by the above, is supplied to the light emitting diode 4, causing the light emitting diode 4 to emit light.

The illuminance detection circuit 14 detects the presence or absence of an electromotive force from the solar cell 1, and only when there is no electromotive force and the power generation waveform detection circuit 13 is charging the battery 15, the output signals from both circuits are used to control the control circuit 12. For example, by turning on a transistor and operating a relay connected to the transistor, a circuit that supplies power from the battery 15 is made conductive, and the light emitting diode 4 is turned on.
to emit light. That is, an automatic switch circuit is constructed by combining each circuit. According to the above configuration, since the engine drive is detected from the same lead wire as the lead wire 8 that serves as the power supply path to the light emitting diode 4 etc. at night, the lead wire can be shared. There is no need to provide a separate one. Moreover, since the lead wire 8 is also a supply path for supplying the electromotive force of the solar cell 1 to the battery 15 during the daytime, the solar cell 1 charges the battery 15, the battery 15 supplies power to the light emitting diode 4, etc., and the engine. Only one pair of lead wires 8 is required for drive detection, and the wiring structure can be greatly simplified. Therefore, when installing the solar cell module of the present invention in a vehicle, it is only necessary to connect the pair of lead wires 8 to the battery 15 of the vehicle, which greatly simplifies the work. Light from the light emitting diode 4 is led out from the side pole 3. Therefore, this light illuminates the vicinity of the fender side of the vehicle and measures the distance between the fender side and the opposing object. The light output from the side pole 3 is preferably colored light such as yellow, red, or blue.

<Effects of the Invention> As explained in detail above, in the present invention, a side pole with an automatic switch circuit having a light emitting function is attached to a solar cell module for battery charging, thereby constructing a fender side contact accident prevention mechanism.
Wiring is completed by simply connecting the solar cell module to the battery terminal mounted on the vehicle via lead wires. Therefore, the installation work is extremely simple, and a decrease in capacity caused by self-discharge of the battery can be compensated for at the same time.
