Nowadays, there are more and more cars in our world and gasoline is about to be exhausted, which has also polluted the natural environment. People increasingly need fast travel, so we need a new source of automobile energy to solve people's problems. Below I will mainly explain the principle and assembly of a solar car.
Modern car engines are driven by the combustion of gasoline, but it is different if we use solar energy as energy if we use solar energy on the outer shell or on the top. car, if you install a solar panel, you can convert the sun's energy into electricity under the irradiation of the sun. We can also store excess solar energy during the day so that the stored electricity can be used on cloudy days or at night. This relieves people of stravel-related concerns, save gasoline and protect the natural environment.
And what is solar energy? Solar energy is energy that can radiate heat from the sun to the earth through light. Solar energy is green energy that converts sunlight into electricity. Since the birth of life on earth, all life has needed sunlight. We usually use the sun to dry our clothes after washing them. Solar energy is inexhaustible.
The steps for assembling a simple solar car. The main parts include solar panels, wires, motors and motor frames, battery boxes, 4 wheels and bearings, and some small boards. etc. ...First take out a relatively large wooden board and two square wooden sticks, and use glue to stick the wooden sticks to the long sides of the board.e wood. Then glue the battery box to the board, insert the wires into the recessed part of the motor, press it onto the motor frame, and glue the motor assembly to the other end of the board. Then stick a square wooden board to the center of the board, stick a small round wooden stick to the square wooden board, and then stick double-sided tape on a round wooden board. Then stick the other end of the wire to the motor between the double-sided tape and stick the solar panel on it. Finally, drill two small holes in each of the two wooden sticks at the bottom, thread the steel wire and insert the bearings, press the wheels on both sides of the steel wire and that's it.
?If all cars in the world are equipped with solar panels, then humans will no longer have to worry about gasoline, nature will also be improved and travel people will be more practical.
To create a modelsolar car, the main thing is to be fast and drive on a track 15 cm wide. Materials: a plastic version of the engine 19 cm long.
Present it. solar car:
Solar cars
The fuel used in cars is gasoline and diesel, which are extracted from petroleum. However, fossil fuels like oil are not renewable. The more you use, the less you use, and they will eventually run out. According to scientists, all proven oil reserves in the world will be exhausted around 2020. As a result, cars are likely to be "starved" and humans will face energy challenges.
On the other hand, oil itself is a valuable chemical feedstock that can be used to make plastics, synthetic rubber, and synthetic fibers. Burning oil as fuel is not only a shame, but also pollutes the environment.nment on which human beings depend for their survival.
The only possible way to solve this problem is to accelerate the development of new energy sources. Solar energy is the leader among these newly developed energy sources.
The surface of the golden-flamed sun is a sea of raging fire, with a temperature of around 6,000°C. Inside the sun, the temperature reaches more than 20 million degrees. Therefore, solar energy continuously emits a large amount of light and heat, bringing light and heat to humanity. It has also become an inexhaustible cornucopia of energy.
Converting sunlight into electrical energy is an important way to use solar energy. The first photovoltaic cells were manufactured as early as the 1950s. Install the photovoltaic cell on the car and use it to continually convert sunlight into energy.electric power to make the car move. This type of car is the new emerging solar car.
You see, a solar car is equipped with densely packed honeycomb-shaped devices, which are solar panels. The iron wings usually seen on artificial satellites are also solar panels that provide electricity to the satellites.
Solar cells are generally divided into silicon cells, cadmium sulfide cells, gallium arsenide cells, etc. depending on the semiconductor materials used. Among them, silicon solar cells are the most commonly used.
Silicon solar cells come in round, semi-circular and rectangular shapes. On the battery are small paper-thin silicon wafers. By uniformly doping boron on one side of the silicon wafer and phosphorus on theOn the other side, and by installing electrodes on both sides of the silicon wafer, it can convert light energy into electrical energy.
On top of the Libitblick II solar car there is an arc-shaped solar panel on which numerous solar cells are neatly arranged. Under sunlight, the electrodes of these solar cells generate an electromotive force between them. the two electrodes, then a current is emitted through the wire connecting the two electrodes.
Usually, silicon solar cells can convert 10% to 15% of solar energy into electrical energy. It is durable, clean and does not pollute the environment. However, the photoelectric conversion rate is lower. In recent years, the United States has developed high-performance solar cell with photoelectric conversion rate. 35%. The photoelectric conversion rate of solar cells manufactured with chis technology is 24.2% and the cost is equivalent to diesel power generation. This has opened up broad prospects for the application of photovoltaic cells in automobiles.
< h3>What you should pay attention to when manufacturing solar cars. ProblemSolar panel + motor - Pay attention to the speed of the motor, the faster it will run. the battery panel will decrease the engine speed. The key is that the boat with only one engine can easily deviate and cannot be corrected. The only way to make it go faster is to use a large gear with a small gear to increase the speed. speed
1. First of all, the car must be relatively strong, have a relatively low center of gravity (the area between the four wheels can be increased appropriately), and have a light weight. You should also pay attention to the degree of lightness. fixation of the wordeur and coordination of cable layout. It's best to be able to secure them so they don't look too scattered and resonate easily or even fall apart;
2. I don't know how big you want to get. As for consumables, I suggest you go to Taobao to search for them, and then go to the nearby toy or equipment store, you can also refer to them. to the car model already formed in terms of structure;
3 If you need to make a perfect solar car, it is recommended to go to a professional forum or group to discuss it... .
