Fu Zhi pouted when he heard this, there was no bad guy in Mingzhu's eyes.

"Mingzhu, you can't have the heart to hurt people, you can't have the heart to defend people, who knows if that guy is deliberately showing favor to you, and then bullying you behind your back."

Fu Zhi couldn't help but poke the little girl's soft little face and told her, "Anyway, you remember, if that guy bullies you, you must tell Uncle Song and Aunt Lu, otherwise tell me." ”

It's not that there are no such people in the compound, he has seen a lot of people in front of them and people in the back.

He had to give Mingzhu a vaccination so that she wouldn't be bullied.

"Brother Fu Zhi, Sister Baozhu is really good, I don't want you to say that about her." Song Mingzhu subconsciously bit her lip and stared at him with a serious expression.

"And this matter is originally my fault, Sister Baozhu is the most innocent victim." She was a little angry.

"Sister Baozhu won't bully me behind my back, if you say that again, I will ignore you."

Fu Zhi was a little jealous, and always felt that Gu Baozhu was a little evil.

"You've only known her for a long time, just one day, you know who she is, just speak for her."

It's only been a day, and I'm very angry that my future daughter-in-law is Sister Baozhu when she opens and closes her mouth.

"I just know." Song Mingzhu stared at him and said word by word, "Sister Baozhu is a good person, if you want to say that she is not good, I won't play with you in the future." ”

The little girl was stubborn, and Fu Zhi had no choice at all.

In the end, he could only compromise, but he still told a few words, and he did not continue until the little girl was really angry.

Gu Baozhu didn't know what was happening in the compound, and he didn't know that someone was arranging himself.

She's modifying the electric car's motors and assembling larger solar panels.

After all, to drive an electric unicycle, a lot of electrical energy is required, and it is still necessary to increase the transmission power of the motor.

For several days, Gu Baozhu was busy in the laboratory.

In addition, she also asked Director Guo to help her customize the shell of the tricycle, which can be used without many good materials.

An electric tricycle is a three-wheeled vehicle used to pull goods or people with electric energy as the power and the motor as the drive.

Such tools were common in later generations, but not in this era.

The first is the motor drive problem, and the second is the battery problem, but now these are not problems, all solved.

She'll be able to make an electric tricycle in no time, and that's great!

The electric tricycle she made uses tubular large-capacity, left and right lining, deep discharge, and traction solar panels, which can adapt to the requirements of continuous discharge for long-term work, and the solar panels have been used normally for ten years, and the internal content is attenuated by 80%.

The electric tricycle motor adopts a DC series-excited traction brushless motor, and the motor is equipped with a speed-regulating and power-increasing device, which is not easy to be damaged under normal use and ensures strong output power.

However, the cost of this electric tricycle is about 1000, which is very expensive for the moment.

However, compared with cars, the cost is simply not on a step, and it is very cheap.

As soon as they heard that Gu Baozhu's electric tricycle had been built, Hu Lao and Li Wei came over, and then Hu Lao was shocked again.

"This is the electric tricycle you built?" Hu Lao walked around the electric car several times.

"It's like a car, a tricycle that doesn't require manpower?"

Hu Lao looked at the blue tricycle in front of him in disbelief, can this really run like a car, does it really need manpower?

Gu Baozhu nodded and patted the position behind him, "Of course, do you want to sit on it and try it?" ”

"Comrade Xiao Gu, I'll come." Li Wei didn't dare to let Hu Lao take risks, so let's come.

Gu Baozhu shrugged his shoulders so-called, "It's okay." ”

"Brother Li, come up, I'll take you around the scientific research institute."

Gu Baozhu sat in the driver's seat, couldn't help but patted the back bucket behind him, and motioned for him to sit down.

Levi was not stage frightened, he took a step with long legs and stood up directly.

The space of the tricycle is not small, and it can be done for three or four people if it is neat.

He found a more comfortable position to sit down, and when Gu Baozhu saw him sit firmly, he waved his big hand, "Old Hu, let's take the first step." ”

Gu Baozhu plugged in the key and started the electric car.

In the next moment, Levi felt that the electric car was slowly moving forward, and after a while, the speed of the electric car began to increase.

Then, they quickly left Hu Lao behind, leaving Hu Lao with a shocked face!!

Li Wei couldn't help but ask, "Comrade Xiao Gu, isn't this really a car?" ”

Isn't it a car without manpower?

Gu Baozhu shook his head, "This is an electric car, and it is far from a car." ”

Electric vehicles only need motors, batteries, and control systems to drive, but cars need engines, and the engine is not simply modified to be on the road.

Of course, it can also be made into an electric car.

It's just that the distance will not be too long, it is not very useful, the cost is still high, and it is not as convenient as an electric tricycle.

"I don't think it's any different from a car!" Levi sat on it with a look of amazement.

He looked around curiously, and then glanced at Comrade Xiao Gu, who was driving in front.

"Comrade Xiao Gu, is there anything else you won't have?"

If it weren't for a car, how could it run so fast?

The only difference is that four wheels have become three, and this Comrade Xiao Gu is really a genius.

"Brother Li, this is an electric tricycle, the main energy consumption is electric drive, the speed is not as fast as the car, and the distance traveled is not as good as the car."

"Of course, the speed of electric vehicles is much faster than that of bicycles, and they are not driven by manpower, saving time and effort, and the most important thing is that they can be started by basking in the sun, which not only saves energy but also has no pollution, and it is a very good choice for short distances."

"Long distances are not recommended!"

"Brother Li, sit tight."

Gu Baozhu accelerated violently, and Li Wei almost collapsed under the action of inertia, but fortunately, he used his strength to stabilize his body, otherwise his chin would have hit the car.

Feeling the extraordinary speed, Li Wei once again sighed at the genius of Comrade Xiao Gu.

Gu Baozhu pulled Li Wei back to the same place, Li Wei was still dizzy, so Hu Lao hurriedly ran over and walked around the electric car, his eyes shining.

Gu Baozhu didn't bother him, let him watch slowly.

At this time, Hu Lao was already addicted to it, and he couldn't help but take a closer look at the structure of the electric car, the structure is not very complicated, and the principle is very simple.

The working principle of a three-wheeled electric vehicle is based on electric drive, and its power system consists of a battery, a motor, a control system, and supporting circuits.

In the power system, the battery is the power source of the electric vehicle, the control system controls and manages the entire power system, and the motor is the core equipment for transmitting electric energy.

The motor of this electric car is much more powerful than the motor that drove the small plane before, and Hu Lao's brain is calculating rapidly.

After a rough estimate of the weight of this electric tricycle, the power of this motor is at least more than 1,000 watts.

If you extrapolate according to the formula, this electric car can travel 100 kilometers when fully charged, but there should be some differences between actual and theoretical calculations.

Not just the motor, but also its control system.

It wasn't something that could be done overnight, but this little girl did it.
