Two solar panels are installed on the visor part, and six solar panels are installed on the cap body. The total area of 8 solar panels is 432cm ² . Due to the irregular shape, there is an area that cannot be typeset, and the area that can be effectively typed is about 90%, that is, the effective area is 390cm ² . In addition, when it is made into a hat, the posture of each solar panel is different, so it is impossible to receive direct sunlight at the same time, and illuminate the hat from different angles. The projected areas are different, and the actual light receiving area can be converted to 60% of the original effective area. %~75%, that is, the light receiving area is 234~293cm ² , and the power is 0.96~1.2W under the environment of light intensity 1000W/m2, spectrum AM1.5, and temperature 25°C. In this state, charge the lithium battery of the Bluetooth headset (capacity 120mA*h), and it can be fully charged in 28 to 23 minutes.

This solar hat-type Bluetooth headset, put on the hat and wear the Bluetooth headset, and the outer surface of the hat is covered with flexible amorphous silicon thin-film solar panels. As long as you move in the bright sunshine for half an hour, the lithium battery of the headset It can be fully charged, and charging and use can be carried out simultaneously. In addition, in order to keep the hat cooler in hot weather, there is a fan driven by a small motor at the back of the hat (the fan of the small motor can be taken off), which is fixed on the stretchable belt of the hat. An LED light head is installed at the front end of the visor of the hat for emergency lighting in a dark environment. There is a prominent switch button on the top of the hat, press the first button to start the fan, press the second button to turn off the fan and turn on the LED light, and press the third button to turn off the LED light. Cycle like this.

This solar hat-type Bluetooth headset avoids the inconvenience of nowhere to charge during outdoor sports; overcomes the disadvantages of being unable to use conventional Bluetooth headsets when charging; it has high power and fast charging, and the solar panels are divided into special-shaped blocks according to the shape of the hat, and finally combined It is relative to the rectangle, generally the solar panel is easy to process), which realizes the maximum utilization of all parts of the hat that can receive sunlight, so the total power is increased, and it only takes about half an hour to fully charge; it is more reliable to wear, and listens The continuity experience of songs is better. The wires and other parts of conventional Bluetooth headsets (due to gravity) pull the in-ear speakers down, while the wires and other parts of this Bluetooth headset are in the cap above the ears, which will not There is such a pull-down situation, so the same style of in-ear speakers, this solution is more reliable to wear; it is more convenient to find, when the conventional Bluetooth headset is forgotten at home, it is very difficult to find due to its small size; the Bluetooth headset of this solution is a hat, It is very easy to find, not easy to lose, and safer; conventional Bluetooth headsets, especially single-ear ones, can easily slip off due to sports or not being worn tightly. On the hat, there is no risk of loss.

The above descriptions are only preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present utility model shall be included in the Within the protection scope of the present utility model.
