Chapter 221 Done

When the optimization of the two electric motors was completed, he also began to conduct miniaturization research and development on this basis.

The first thing to determine is the position on the powered exoskeleton. Only when the installation position is determined can the subsequent size and appearance be determined.

It can be seen from this that the powered exoskeleton is not a single machine, but an entire system.

Due to the external shape of the powered exoskeleton, there is not much design space to place large-volume parts, which is only the chest and back.

So he didn't have many choices. After thinking about it carefully, he decided to put it on his back.

The back is only so large, so the size of the motor must be as small as possible, and the output power must be as high as possible while maintaining a small size.

This contradiction is vividly displayed in the current motor, and it also makes the development of this motor much more difficult.

Finally, the size and location of the main power source motor were determined. First, the location was determined to be on the back close to the buttocks.

In terms of size and appearance, the motor is in the shape of a rectangular parallelepiped. The dimensions are length: 30 cm, width: 15 cm, and height 15 cm. The length is almost the same as the width of the human body.

And this is not just a single electric motor, but a machine that integrates the main cylinder used in the hydraulic system and the cooling system of the motor itself.

It is not an exaggeration to say that it is a main power unit, and the output power of the electric motor reaches 26kw and 35 high-power horsepower.

It may not be intuitive to say this, but you must know that even a 125cc motorcycle only outputs 8-11 horsepower.

The electric motor he has developed now is equivalent to two 125cc motorcycle engines, and it is very powerful!

After the main power unit is designed, the next step is the battery pack that provides energy for the motor. For the battery pack used on the power exoskeleton, of course, the bigger the better.

But the size is limited to the size that can be put down on the back.

Moreover, the battery is not composed of 18650 power batteries this time, but uses the same technology as mobile phone batteries, that is, the entire battery pack is designed as a whole.

The length, width and height are designed to be 30*10*40, and its capacity reaches 60kwh.

With this battery capacity, the main power unit can run at full power for a full 14 hours. This kind of usage time can fully make the powered exoskeleton he designed practical.

The main power and energy sources have been determined, and the next step is to carry out the main design.

The first is the main material. It must not only have sufficient strength, but also have enough toughness so that the frame that makes up the main body can withstand huge forces.

In terms of the frame structure, considering the use scenarios of the powered exoskeleton, the tubular structure on the market is not used, but is forged from a single piece of alloy.

Just from the appearance, you can see how strong this exoskeleton is.

The hose material in the hydraulic system has also been innovatively developed. The hose material is a lightweight and extremely flexible alloy.

It has excellent performance in terms of pressure resistance, and can be welded at the connection, which strengthens the weakest point in the hydraulic system.

After all the mechanical parts are finished, all the simple parts of the powered exoskeleton are finished.

The next electronic control system is the most difficult. It is not only the writing of the control system, but also the development of various sensors.

These sensors are the most important link, and a lot of research and development needs to be done on the types of sensors.

Among them, many types of sensors such as angle sensors, myoelectric sensors, ground sensors, muscle pressure sensors, etc. need to be developed and manufactured.

Only by using a variety of sensors together can the powered exoskeleton achieve what people want.

The most commonly used one is the muscle pressure sensor, which is the main force in collecting the wearer's movements.

The design of a powered exoskeleton is not accomplished overnight. Even if he has a virtual laboratory, it cannot be completed in a short time.

The sky outside gradually became brighter, and Li Yun moved around him. Feeling the movement of the people around him, he also withdrew from the laboratory.

I glanced at the clock on the wall and saw that the hands had reached nine o'clock in the morning.

The two lay on the bed for a while, then got up to find something to eat. They started cooking in the kitchen while playing around. By the time they finished eating, it was already almost one o'clock.

After dinner, Li Yun did not continue to be with him, but went to work in the company. He seemed to be doing nothing at home, which was indeed a bit decadent. He also had the idea of ​​going to the company.

And he had just arrived at the company, and before he took a sip of the cup of tea he had just brewed in the workshop lounge, Wang Yuesheng's call actually came in.

After chatting with Wang Yuesheng on the phone for a long time, when he hung up the phone, a strange expression appeared on his face.

The strange expression gradually turned into anger as he thought about it. Having not paid attention to the news recently, he immediately took out his mobile phone and searched for relevant news.

Starting from the news about the change of manager of Pakistan Railway, to the appointment of the new manager of Pakistan Railway, to the self-explosion bombs that appeared in Pakistan Railway a few days ago, everything is full of conspiracy.

A discerning person can tell at a glance that there must be bad elements obstructing it. After reading and analyzing the information, he also made a decision in his heart.

"Comrade Li Zhenhua, I solemnly ask you to design a commuter car with strong enough protective capabilities to provide strong protection for our compatriots working overseas."

Recalling what Wang Yuesheng said to him on the phone before, which was actually a request, he immediately took action.

Isn't it just a car with strong enough protective capabilities? It's not like he hasn't designed it before. Moreover, considering the energy situation on the Pakistan Railway, this time the vehicle was designed not to use electricity, but to use traditional fuel power. .

An engine from Jiefang Power with a displacement of 15 liters and a total horsepower of more than 600 horses came into his eyes. This engine is used in trucks.

And this time he did not plan to start the design from scratch, but planned to carry out bulletproof modifications based on the liberation of the truck. Moreover, their company has jointly established a company with Changzi Automobile to produce bulletproof vehicles. This model can be directly put into the new company after it is designed.

And this time it was a modification, so the development speed was extremely fast.

Soon a huge vehicle with an extremely incongruous appearance was born from his hands. It was actually modified from the head of a truck.

It didn't take him much time, it only took one day to develop it, and it took more than a week to complete all the drawings.

After it was completely figured out, Li Zhenhua immediately called Wang Yuesheng back.

"Chief, I have designed the car, and I plan to produce it in our new joint venture with Changzi Automobile.

Moreover, this vehicle should be produced very quickly, because it is completely modified from a truck head and can be produced in large quantities in a very short time.

It also allows overseas compatriots to use it as soon as possible and get protection as soon as possible in terms of safety. "

When Wang Yuesheng received his call, he never thought there would be such a plan. When he called before, he always thought it would be a redesign like Qingniu.

But after listening to his explanation, he admired Li Zhenhua very much and never thought that there would be such a plan.

After he accepted what Li Zhenhua said, he always had a strange feeling in his heart, but he never thought there was something wrong.

"Okay, I've considered it very comprehensively. Let's proceed according to your plan. I'll hang up first. I still have to make a phone call with the Ministry of Foreign Affairs."

After he hung up the phone, Li Zhenhua also sent the transformation plan to the new company.

After Wang Yuesheng made a phone call with the Ministry of Foreign Affairs, he finally knew what the strange feeling was because he received the renderings sent to him by Li Zhenhua.

Isn't this the appearance of an off-road RV, and coupled with the bulletproof technology developed by Li Zhenhua, the effect such a vehicle can achieve will definitely shock a group of people.

After Li Zhenhua sent the plan to the new company, he stopped paying attention to the follow-up. He still had a big toy that he had not finished yet!

As for the new company he cooperated with Changzi Automobile, after receiving the complete transformation plan, it immediately transferred ten front chassis from Qingqi Automobile.

Once all the required items were in place, the modification of the bulletproof armored bus began.

It could originally be used as a tractor with 600 horsepower, but it was simply changed to the size of a minibus, making the vehicle's protective armor 15 centimeters thick.

Of course, the cost is not cheap. The modification price of such a car alone is as high as 2 million, and the front chassis and other items are also 300,000 to 400,000. The total price is almost between 2.6 and 3 million.

More than a month has passed since he sent the plan to the new company, and the first batch of ten vehicles has rolled off the assembly line.

The Ministry of Foreign Affairs can be said to be eager to see this car. This car has not been deployed overseas for a moment. They are always on tenterhooks, worried that there will be another attack.

When I learned that the car was offline, I immediately rushed from Peiping to Dongshan Island City to see the car that had just rolled off the production line.

After getting off the plane at Daocheng Airport, we went straight to Qingqi Automobile Co., Ltd. A factory here was transferred to a new company by Changzi Automobile as a shareholding asset. The new company was called Daocheng Divine Beast Jiefang Automobile Company.

The leader of the Foreign Affairs Department was led to the parking lot by the staff, and immediately saw ten all-white cars neatly placed in the parking lot.

Call it a truck, its cabin is so long, call it a bus, and it doesn't look like it in appearance. There is no name that can describe it. The closest thing to it is an off-road RV.

Although the appearance is a bit weird, the foreign affairs department was extremely satisfied with the performance that they later learned about. Even if the price is as high as 2.8 million, they think it is worth it.

As long as this vehicle is deployed overseas and the safety of our compatriots is greatly protected, it will be worth it no matter how much money is spent.

What's more, the general who was targeted by Kongbu elements was also an important figure that Kyushu had assisted in the past.

Without any hesitation, the Ministry of Foreign Affairs immediately made arrangements for the ten vehicles and transported them to Pakistan immediately.

Five days later, the compatriots in Pakistan were replaced by this car as a means of commuting to and from get off work. The model of the car was named Ciao among the Five Sons of the Tiger. As for the model in Jiefang, it was CA620FD-8*8.

Li Zhenhua had no idea that the car had been built. He had been perfecting the design of the powered exoskeleton in the virtual laboratory during this period.

Compared with the design plan more than a month ago, great progress has been made at this moment, and during this period, the plan has been optimized to the end.

The feet were completely wrapped, forming an iron boot, and connected to the boot were extremely thick leg supports.

A semi-wrapped structure is only used in the knee area, and there are micro motors with a power of 1kw on the outside of the thigh and calf.

As for the upper body, the spine is the thickest. The upper limbs extend outward from the spine, and the battery pack and main power unit are placed on the back.

The overall appearance does not look like an exoskeleton, but more like a semi-finished exoskeleton armor.

When he finished the last control system that needed to be debugged, the powered exoskeleton was born from his hands.

In terms of power, there is a 26kw main power unit, plus eight 1kw micro motors, with a total power of 34kw and 46 horsepower.

The hydraulic pressure used for transmission ensures high accuracy and sufficient response speed, and the power output is also maximized.

The exoskeleton he created can easily carry 600 kilograms of weight, and his maximum lifting weight is 800 kilograms, but this maximum lifting weight cannot be used for a long time.

The curb weight of this entire set of exoskeletons reaches 80 kilograms, but it exerts an effect ten times its own weight.

In the virtual laboratory, Li Zhenhua pushed the keyboard that appeared on the front mask forward. Although he didn't feel tired, he still stretched as usual.

After stretching, he unplugged the data cable between the computer and the powered exoskeleton, and walked towards the powered exoskeleton hanging in the air.

Come closer and open all the locks of the powered exoskeleton.

Then he turned around and walked backwards towards the powered exoskeleton until he retreated into it.

He felt the powered exoskeleton on his back, knew it was in place, and bent down to put on the equipment starting from his feet.

First, I took off my shoes and put my socks into the boots of the powered exoskeleton. Why can't I put on shoes?

That's because there are sensors inside the boots, and these sensors can only work when they come into contact with the person's body.

Fastening all the buckles on the boots, the boots were already quite large, but when he fastened the buckles, they immediately became snug.

After the boots are put on, the next step is to put them on up the legs.

The calves, knees, and thighs extend all the way up. When the connection to his upper body and chest tightened, he powered on the powered exoskeleton.

At this point, most of the parts have been put on, and only two arms are left on the whole body.

Then he first raised his right arm to the predetermined position, and his left hand began to fix all the buckles on the right arm.

Wait until the right hand is fixed before proceeding to the final step.
