Rebirth 84 Everything depends on hands

Soon after, Chen Feng saw that the electric car was almost unloaded, so he asked Liangzi to go down and pick up a large package. Liangzi held a large package in both hands and carried it to the lounge, then placed it heavily on the ground.

.

After Chen Feng unpacked the package, he took the things inside and started to install them. Others looked on and didn't know what it was for a long time.

When Chen Feng finished assembling all the spare parts, a strange thing appeared in front of everyone. There was a small wheel on each side. There was obviously a pedal in the middle of the wheel. There was an erected support rod in the middle of the pedal, and above the rod was

A car seat, what on earth is this? The brothers glanced at each other, and then looked at Chen Feng.

"This thing is called an electric balance car!" Chen patted the car seat and said to several people with a smile.

Electric balancing car? Several people looked at each other, obviously not understanding how this thing worked. The balancing car was relatively unfamiliar to them, but it was simply too familiar to Chen Feng. In later generations, Chen Feng's favorite

It's this balancing car. I once rode a ***-wheel balancing car in the streets and alleys.

So when Mr. Zhong opened the battery car, Chen Feng thought that since the battery could be produced by himself, it would not be a problem to produce a balancing car, so he informed Mr. Zhong of the principle of the balancing car. After a long period of research and development by Mr. Zhong,

Later, just before Chen Feng came to Beijing, Teacher Zhong informed Chen Feng that the experiment on the balancing car was basically completed, so before Chen Feng left, he asked Teacher Zhong to go to Fenglan Electric Vehicle Factory to build the experimental balancing car.

"Brother, what do you call this thing, a balancing car?" Huzi looked at the thing on the ground and asked Chen Feng, "How does this thing move? Demonstrate it to us."

Chen Feng smiled slightly, adjusted the height of the seat, and then sat on the seat of the balance car to demonstrate to everyone.

Seeing Chen Feng riding the balance bike back and forth in the lounge, several people felt itchy. Especially Liangzi who pulled Chen Feng off the bike.

"I'll go, what's the point?" Liangzi pulled the car into his hands and said to Chen Feng, "Brother Feng, come down and let me try."

Chen Feng smiled and handed the balancing car to Liangzi. As a result, Liangzi fell off as soon as he got on it. He tried several times without success. Huzi pulled Liangzi away and went up to test it himself. The result was the same as Liangzi.

, let alone making the balance car move forward, it is even difficult to keep it steady on the balance car.

On the contrary, after Lu Peng watched from the side, he carefully got on the balance car, and then reluctantly kept himself balanced on it. After maintaining his balance, he carefully leaned forward, and the balance car started to move forward.

It's just that Lu Peng hasn't fully mastered the balance car yet. Seeing that he was about to hit the wall, he didn't know how to turn. After jumping off the car, he swung and grabbed the balance car.

Several people gathered around the balancing car. Chen Feng held the balancing car and explained to them the working principle of the balancing car.

Chen Feng pointed to the balancing car and said to several people, "The working principle of the electric balancing car is to use an attitude sensor, the so-called gyroscope, to monitor the pitch state and state change rate of the body, and drive the motor to generate forward or backward acceleration.

Achieve the effect of front and rear balance of the car body.”

As he spoke, Chen Feng found a piece of paper, drew a rough outline of the gyroscope, and explained it to several people in detail.

"Take the driver standing on the car and the longitudinal axis of the vehicle's overall center of gravity as the reference line. When this axis tilts forward, the built-in electric motor in the body will generate forward force. On the one hand, it balances the movement of the person and the vehicle forward.

The dumping torque, on the one hand, generates acceleration that makes the vehicle move forward. On the contrary, when the gyroscope detects that the driver's center of gravity is tilted backward, it will also generate a backward force to achieve a balancing effect."

After Chen Feng finished speaking, he looked at a few people. Hu Zi and others nodded in understanding. Lu Peng understood the reason and nodded seriously beside him, and then said to Chen Feng, "That is to say, the driver only needs to

By changing the angle of your body and leaning forward or backward, the electric balance vehicle will move forward or backward according to the direction of tilt, and the speed is proportional to the degree of tilt of the driver's body."

Chen Feng smiled and snapped his fingers. Lu Peng was a technician. He almost understood such a complicated thing once it was explained to him. It seemed that he knew everything. No wonder he could control the balance from the beginning.

car, it was obvious that he had understood the principles behind it when he was driving it just now.

Liangzi scratched his head beside him and asked confusedly, "Brother Feng, how does it know whether my body is leaning forward or backward? This thing is really amazing."

Chen Feng raised his hand and hit Liangzi, "Didn't I tell you before? It relies on the gyroscope! The gyroscope detects the changes in the car body and transmits the data to the microcontroller, and the microcontroller transmits it to the motor!"

After hearing this, Liangzi still shook his head. Although he didn't understand, he knew that if he didn't understand the working principle, it would be fine if he didn't delay selling and riding this thing. So he smiled and asked Chen Feng, "Brother Feng, do you plan to put this thing on

Is there any publicity in the capital? If this thing is publicized, it will definitely be more popular than electric cars!"

Chen Feng shook his head slightly. After telling a few people about the cost of this electric balancing car, several people stuck out their tongues and said, "This thing is not something that Chinese people can afford for the time being. This is something I developed for the European market."

product."

Chen Feng patted the electric balance car with some regret and said that if the economic level of the Chinese people improved significantly, he could consider taking the lead in production and sales, but he cannot do so now.

"Brother, why did you send it to the capital?" Huzi asked, shaking his big head, "Don't break such an expensive thing!"

Chen Feng raised the corner of his mouth slightly and said to several people, "Although the Chinese can't afford this thing, it doesn't mean that people from other countries can't afford it, especially countries like the Chariot Country and the Romantic Country.

They accept novel things quickly and are willing to try them.”

Several people nodded. In recent years, Fenglan has produced many products, which are only aimed at the European market, not because the people in their own country cannot use them, but because of the price. It seems that this is another product specifically targeted at the European market.

"You have forgotten, isn't Watson in the capital?" Chen Feng said to a few people with a sly smile, "We can't meet him in vain. Give him a car and let him go back and brag for us Fenglan!"

"Brother Feng, are you planning to let Watson do live advertising for you?" Liangzi said with a smile beside him.

"Nonsense, can I help him in vain?" Chen Feng sniffed, "You have to get some benefits back, right?"
