Zhongshan pupils invented helmets to solve heat dissipation

In hot summers, people who wear helmets and motorcycles and wear hard hats will find it difficult to wear and wear them for a while. Some motorcyclists don’t wear helmets, which is very dangerous. The fifth grade student Lai Yujin of Shiqi Primary School in Zhongshan City thought of a good idea. Installing an exhaust fan on the helmet would solve this problem. At the same time, he considered using solar batteries to provide power, and also installed lights on the front for lighting.

See my mother sweating ideas

Usually go to school, Lai Yu Jin's mother is riding a motorcycle to pick him up. When he was wearing it in the summer, his sweat and mother's sweat dribbled. He also saw a lot of workers wearing hard hats and it was also very hot. Lai Yujin thinks how to heat the helmet? He thinks of a fan and thinks that the fan that fits on the helmet is the one on the computer case. Lai Ruanjin said this idea to teachers and parents, and they all feel very good. In the following, Lai Yujin faced the problem of how to turn the fan up.

Of course, solar energy is the best. Before Lai Sui-Jin, he dismantled the solar panels of toy cars. However, through the universal metering current, the current is too low to drive the fan. Then think of a battery, you can save the energy generated by solar energy, and then turn on the switch when necessary, you can provide enough fan power to rotate. In the beginning, Lai Rujin considered heat dissipation only. Later he discovered that there was an indicator light on the solar battery, and he thought that he could install the light on the front and could also illuminate when needed.

Love to disassemble things from childhood, do manual work

Although the entire work takes a long time to consider, the actual production time is very short, only two hours. The hole in the fan behind the helmet was Lai Jinjin, who first drew a circle with a compass, and then used a soldering iron to iron the helmet along the well-marked mark. The front vent also operated like this. The solar battery on the top of the helmet is relatively simple. Just use double-sided adhesive.

The production process is so fast, thanks to Lai Kun's frequent demolition and hand-crafting. “I used to repair mobile phones. I have been in the room for more than ten years. There is a room dedicated to putting tools in my family. I used to play regularly when I was a kid, and he often disassembled some of his mobile phones,” said Lai’s father. The most expensive thing that Lai Jin dismantled was the tablet computer. That was when he was in the third grade. The parents are not at home. He was curious to take the tablet apart. The screen and the host were connected by cables. He didn't know how to open the cable and the line was torn. When the parents returned, they found that the tablet could not be repaired. Afterwards, Dad thought he was out of curiosity and forgave him for telling him what the various parts were and what the principle was.
