Chapter 221 Done

When the optimization of the two motors was completed, he also started to miniaturize them 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 also be seen from this that the powered exoskeleton is not a single type of machinery, but a whole system.

Due to the external shape of the powered exoskeleton, there is not much design space, and the position where large-volume parts can be placed is only the front chest and the back.

So there were not many choices for him, after careful consideration, he decided to place it on his back.

The back position is so big, so the volume of the motor must be as small as possible, and the output power must be as large as possible while maintaining a small volume.

This kind of contradiction is vividly displayed on the current motor, which also makes the research and development of this motor more difficult.

In the end, the size and position of the active power source motor were determined. First, the position was determined at the position of the back close to the buttocks.

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

And this is not just a single motor, but a machine that integrates the main oil cylinder used by 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 has reached 26kw, 35 high horsepower.

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

And now the electric motor he developed is equivalent to two motorcycle engines with a displacement of 125cc, and the power is not small!
After the main power unit is designed, there 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 in terms of size, it is limited to the size that the back can put down.

Moreover, 18650 power batteries are not used to form the battery this time, but the same technology as mobile phone batteries is used, 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 has reached 60kwh.

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

The most important driving force and energy source have been determined, and the next step is to carry out the main design.

First of all, the material of the main body must not only have sufficient strength, but also have sufficient toughness, so that the frame that constitutes the main body can withstand huge forces.

In terms of the frame structure, because of the consideration of the use of the powered exoskeleton, the tubular structure on the market is not used, but a whole piece of alloy is used for forging.

From the appearance alone, you can see the strength of this exoskeleton.

The hose material in the hydraulic system has also undergone innovative research and development. The material of the hose is a light and extremely flexible alloy.

It has excellent performance in compression resistance, and can also be welded at the connection, which strengthens the weakest part of the hydraulic system.

And all the mechanical parts are finished, and the simple parts of the powered exoskeleton are all made.

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

These sensors are the most important link, and there are many kinds of research and development on the types of sensors.

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

A variety of sensors are used together to make the powered exoskeleton reach the desired level.

The most used of them should be the muscle pressure sensor, which is the main force for collecting the wearer's movements.

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

The outside sky gradually brightened, and Li Yun beside him moved, feeling that the people around him were moving, and he also retreated from the laboratory.

Glancing at the clock on the wall, it was nine o'clock in the morning.

The two lay on the bed for a while, and then got up to find something to eat. The two of them were playing around and started cooking in the kitchen. By the time the two had dinner, it was almost one o'clock.

After dinner, Li Yun didn't continue to get tired of being with him, but went to work in the company. He also seemed to have nothing to do at home. He was indeed a bit decadent, and he also thought of going to the company.

And he had just arrived at the company, and he hadn't even taken a sip of the cup of tea he had just brewed in the workshop lounge, when Wang Yuesheng's phone call came in unexpectedly.

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

And this weird expression gradually turned into anger as he thought about it. He, who hadn't followed the news for a while, immediately took out his phone and searched for related news.

From the news of the change of the manager of the Pakistan Railway, to the appointment of the new manager of the Pakistan Railway, to the self-exploding bomb that appeared on the 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 in it. After reading the information and analyzing it, he also has a decision in his heart.

"Comrade Li Zhenhua, I solemnly ask you to design a commuter vehicle with sufficient protection to provide strong protection for our compatriots working overseas."

Thinking back to what Wang Yuesheng said to him on the phone before, it was actually a request, so he immediately acted.

Isn’t it a car with strong enough protection? It’s not like he hasn’t designed it before, and considering the energy situation on the Pakistan Railway side, this time he didn’t choose to use electric power in the design of the vehicle, but used traditional fuel power. .

An engine with a displacement of 15L and a total horsepower of more than 600 horsepower came into his eyes. This engine is used in trucks.

And this time he didn't plan to start the design again, but planned to carry out bulletproof modification on the basis of liberating the truck.Moreover, their company and Changzi Automobile jointly established a company that produces bulletproof vehicles. This model can be directly put into the new company after it is designed.

And this time it is a modification, so the speed of research and development is extremely fast.

Soon a huge car with an extremely incongruous appearance was born from his hands. It was actually refitted on the front of a truck.

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

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

"Sir, I have designed the car, and I plan to produce it in the new joint venture between us and Changzi Motors.

Moreover, the production speed of this car should be very fast, because it is completely modified from the head of a truck, and it can be produced in large quantities and 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 that there would be such a plan. When he called before, he always thought that it would be a new design like Qingniu.

But after listening to his explanation, he also 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 of any problem.

"Okay, the consideration is very comprehensive, then proceed according to your plan, I will hang up first, and I have to make a call with the foreign affairs department."

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

And Wang Yuesheng was on the phone with the Foreign Affairs Department, and he finally knew what was going on with that weird feeling, because he had received the renderings that Li Zhenhua had sent him.

Isn't this just the appearance of an off-road touring car, and with the bulletproof technology developed by Li Zhenhua, the effect of such a car will surely shock a group of people.

After Li Zhenhua sent the plan to the new company, he didn't continue to pay attention to the follow-up of the matter, but he still had a big toy to finish!
As for the new company he cooperated with Changzi Auto, after receiving the complete transformation plan, they immediately transferred ten chassis from Qingqi.

When all the necessary things are in place, the bulletproof armored bus begins to be modified.

Originally, it could be used as a tractor with a strong power of 600 horsepower, but it was only changed to the size of a minibus, which made the thickness of the protective armor of this car reach [-] centimeters.

Of course, the cost is not cheap either. The modification price of such a car alone is as high as 200 million, and the front chassis and other things also cost 40 million. The total price is almost between 260 million and 300 million.

It has been more than a month since he sent the plan to the new company, and the first batch of ten cars have already rolled off the production line.

The Ministry of Foreign Affairs can be said to be waiting for this car. The car has not been deployed overseas for a moment, and they are always in fear, worried that there will be another attack.

When he knew it was off the assembly line, he immediately rushed from Beiping to Dongshan Island City to see the car that had just rolled off the assembly line.

Get off the plane from Daocheng Airport and go straight to Tsingtao. A factory area here was transferred to the new company by the eldest son Automobile as a share capital. The new company is called Daocheng Shenshou Jiefang Automobile Company.

The leader of the foreign affairs department was led by the staff to the parking lot, and saw ten all-white cars neatly placed in the parking lot at a glance.

Let’s say it’s a truck. Its carriage is so long. Let’s say it’s a bus. It doesn’t look like it in appearance. There’s no name that can describe it. If it’s the closest thing, it’s an off-road RV.

Although the appearance is a little weird, but after learning about the performance, the foreign affairs department is very satisfied. Even if the price is as high as 280 million, they think it is worth it.

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

What's more, those who are targeted by Kongbu elements are generally important figures who have been assisted by Kyushu in the past.

Without any hesitation, the ten vehicles were immediately arranged by the Ministry of Foreign Affairs and transported to Pakistan immediately.

Five days later, the means of transportation for the compatriots in Pakistan to commute to and from get off work was replaced by this car. The model of the car was named the cunning among the five sons of the tiger.

Li Zhenhua had no idea that the car had already been manufactured, and he had been perfecting the design of the powered exoskeleton in the virtual laboratory all this time.

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

The feet are completely covered, forming an iron boot, and the boot is connected with an extremely thick leg support.

The half-wrapped structure is only used on the knees, and there are micro motors with a power of 1kw on the outer thighs and lower legs.

As for the position of the upper body, the spine is the strongest, and the upper limbs extend outward from the spine, and the battery pack and active 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 debugging, the powered exoskeleton was born from his hands.

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

The hydraulic pressure used for transmission ensures its high precision and sufficient response speed, and the maximum optimization of power output is also carried out.

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

The curb weight of this whole set of exoskeleton has reached 80 kilograms, but it exerts the effect of 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 according to his habit.

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

Come to the front and open all the locks of the powered exoskeleton.

Then he turned around and backed up to the powered exoskeleton until he was inside it.

He felt the powered exoskeleton in his back, knew it was in place, and bent down to don the suit from his feet.

First, I took off my shoes and put them into the boots of the powered exoskeleton with only socks on. Why can’t I wear shoes?

That's because there are also sensors in the boots, and these sensors can only work when they can touch the human body.

Fasten all the buckles on the boots. The boots were still big, but when he fastened the buckles, they immediately fit.

After the boots are worn, the next step is to start wearing them upwards along the legs.

The calves, knees, and thighs go all the way up.When his upper chest connection also locked, he turned on the power to the powered exoskeleton.

At this point, most of the parts have been dressed, and only two arms are left in 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.
