What is the same thing on the roof of a car as the shark s dorsal fin for?

Some owners may also install a flashing light on the shark's fin. Drivers are usually numb and drowsy when they look at the red tail lights, and it is easy to cheer up when they see this special flashing light, thus reducing the risk of us being rear-ended. In the early days, we didn't have a lot of electronic devices in our cars, that is, a radio.

The radio antenna at that time was like the antenna of the black-and-white television set at home when we were children, with a long one that could shrink. The more advanced ones are still electrically retracted.

<> these signals can be received through the antenna, and can also be amplified and enhanced through the antenna, and then sent out, so that various signals can be exchanged. This is somewhat similar to what that antenna used to do on Big Brother phones. Some of them are the antennas of the original car radio, which look better hidden inside, some cars still have an iron wire, some cars are hidden antennas, and some of them without shark fins are pasted up completely for decoration and look good, and they need to have antennas to receive signals, so early vehicles will be designed with long antennas on the outside.

Moreover, for some advanced vehicles, the antenna can also be electrically retracted. And with the advancement of technology, the antenna of the vehicle is also being updated.

The effective integration of "fashion" and "functionality" with its small size also helps to improve the aerodynamics of the vehicle, and it can be said that it is becoming more and more favored by car enthusiasts. This is the role of the shark's fin in the beginning. The antenna is used to receive FM signals, and at the beginning the antenna is a long stick, which may break or even break if it touches a tree.

That is an antenna, which receives radio waves, designed to be so beautiful, and secondly, it can reduce wind noise and wind resistance when the car is driving at high speed. However, this design at that time had several drawbacks, one was that it was difficult to avoid water when it was windy and rainy; The second problem is the height, when the long antenna on the roof of the car encounters a low basement or even a tree, it will often hang up, bend at light, and pull off directly.

The same thing as the shark's dorsal fin on the roof of the car is an antenna, which can amplify the network signal and also has the effect of eliminating static electricity.

The shark dorsal fin is installed on the top of the car, mainly to reduce the wind resistance, as long as the wind resistance is reduced, then the car's handling and fuel economy will be significantly improved, and some cars will come with a shark dorsal fin from the factory.

It can release static electricity from the human body; Static electricity in automobiles is very common, especially in dry seasons such as winter, and it is easy to generate excessive static electricity. An Australian aircraft maintenance engineer had this while working on an airplane. and successfully patented a spoiler for his car.

The patent for the aircraft maintenance engineer was bought by BMW, which later installed a radio antenna, which was a by-product of shark fin.

<> if static electricity stays in the car for a long time, opening the door first is likely to be hit by static electricity, and refueling at a gas station may also bring certain safety hazards. In the past, people would tie chains and the like to the exhaust pipe to release static electricity, but with shark fin antennas, it's not that much hassle and it looks very elegant. In addition to intercepting these radio waves, the shark fin antenna can also transmit them to various devices in the car that require various radio waves.

(Prevent rear-end collision eight highlights LED lights flashing, so that you can travel happily at night, when the fog is not clear, at this time should continue to step on the brakes to remind the rear vehicle, when the visibility is very low at night, let the vehicle should pay attention to the speed, rainy days, a bang can be, at any time with solar charging, critical moments can save lives.) What's even more impressive is that, in addition to intercepting these radio waves, the shark fin antenna can also transmit these radio waves separately to the various devices needed in the car.

That is the antenna of the car, it can receive some signals, can also release static electricity, and can also reduce fuel consumption, very energy-saving, and can also reduce resistance, reduce noise, the effect is very large.

This small design is actually the antenna of the car, which can better receive the signal and release static electricity well, which can help the car save fuel, can play the role of spoiler, and reduce fuel consumption.

The same thing as the shark's dorsal fin on the top of the car is the antenna of the car, which can help the car receive signals, can release static electricity, and can also help our car save fuel.

First of all, it can be used as an antenna for a car. This little shark fin is actually the antenna of the car. First of all, it can play the role of receiving signals.

After all, everyone knows that the car is a signal for the enclosed space in the car. If you don't add an antenna, the signal will be weaker, so in the past, many cars would install an antenna on the roof to receive the signal. However, with the continuous evolution of automobile design, people also began to think that part of the antenna was not very beautiful on the outside, and at the same time, the demand for height was limited in many places, so the designers chose to make the antenna look like shark fin.

Secondly, static electricity can be discharged. If static electricity is generated at a gas station, the consequences can be catastrophic. When many people ride in a car, static electricity is generated by the friction between the car seat or interior and clothing, which may be transmitted to the human body when it comes into contact with the body. Attentive friends may find that there is usually a chain towed on the ground at the back of the tanker, which is actually to release static electricity and avoid danger.

Small shark fins can improve fuel economy. In short, it helps the car save fuel. The "shark fin" design can share the air resistance of the roof, especially at high speeds.

The same car, if you add a "shark fin", can help reduce fuel consumption, which is also a favorite of drivers and veteran drivers who often drive at high speeds.

Then you can spoiler the effect. If you put a hundred shark fins in the car, the oil will turn on more and more. Although it is a joke, it is impossible to drive more and more oil, but shark fin does have the effect of reducing fuel consumption.

Physically, a car encounters resistance while driving. The faster the speed, the greater the resistance. Without shark fins, a small vortex-like airflow forms above the car, increasing wind resistance and noise.

With the presence of shark fins, the airflow is diverted, which reduces wind resistance, which can effectively reduce fuel consumption and noise.

The thing on the roof of the car, which is the same as the shark's dorsal fin, is the signal receiver, which is often referred to as the antenna.

Function 1: The shark fin antenna is beautiful, which can increase the design sense of the whole vehicle invisibly.

Function 2: The shark fin antenna has the effect of reducing wind resistance and turbulence, which is helpful for the fuel economy of the vehicle.

Function 3: The shark fin antenna can release the static electricity accumulated in the car shell to further protect the circuit safety of the vehicle.

Role 4: The shark fin antenna is generally equipped with a GPS module, and with the blessing of the GPS module, even in places where the mobile phone signal is not very good, the vehicle can better realize GPS positioning and navigation.

Role 5: The shark fin antenna can also realize intelligent interconnection, and the owner can not only realize remote control, but also turn on the air conditioning in the car in advance in summer.

This thing is very useful because it dissipates static electricity accumulated in the car shell, protects the circuit safety of the vehicle, installs a GPS module, realizes the intelligent interconnection function, and turns on the air conditioning in the car in advance in the summer.

It has a brand effect and helps the car to better improve the brand effect. In addition, the aesthetic effect will be better.

With the continuous development of society, our living standards are getting higher and higher. In the past, transportation was not very developed, and it took a lot of time to travel once; But now, because of the reform and opening up, everyone's income is steadily rising, the happiness index has increased sharply, and the mode of travel has become diversified, such as buses, subways, etc., and even cars have entered thousands of households. I believe that friends who have a certain understanding of cars know that the main market of each model is different, and the target consumer groups are also different.

First of all, we all know that when a car is driving, it will generate some resistance. Especially on highways, because the speed of the vehicle is relatively high, the air resistance generated will be greater. It is for this reason that our sedans usually have a flowing structure.

But this is not enough, after all, the engine and transmission are getting better and better. Therefore, the design of the "shark fin" can well reduce the drag and play a certain role in spoiling, thereby greatly reducing the fuel consumption of the car. <>

Secondly, sometimes when we crack open the car door, it is easy to be electrified, which is actually caused by static electricity. Although these electrostatic energies are small, they can cause a lot of damage to the car. As we all know, there are many circuits inside a car, and the presence of static electricity will cause some interference to electronic devices, so it is important to eliminate static electricity.

The presence of "shark fins" can solve this problem very well, and static electricity accumulates on the "shark fins" through conduction wires, and through it is released, and the static electricity in the car disappears naturally. Blind <>

Finally, old cars will have an antenna to receive signals, but this is more of a hidden danger than the antenna. With the advancement of science and technology, many car companies hide the antenna in the "shark fin" for the sake of beauty, which satisfies the vision of many people. There are also some drivers who use the "shark fin" as a warning light, which can often play a key role in rainy days.

Therefore, the existence of "shark fin" has a great sense of meaning, which is also the reason why some car owners need to install it in the later stage.

Receiving signals, sending signals, antennas, and making the car look more aesthetically pleasing, not all cars will have such things on the roof.

Its function is to receive some radio and mobile phone signals and GPS positioning and navigation, it can mainly be used to receive signals.

Receiving the flag signal, sending the flag signal, the antenna, the car becomes beautiful to look at, not all cars have such equipment on the roof.
