Chapter 274

Back in the shelter, while Chen Xin is busy miniaturizing the isotope thermoelectric battery, he is also seriously thinking about how to do the exoskeleton protective clothing.

The manufacture of exoskeletons is a very simple thing for Chen Xin. In fact, it is not difficult to manufacture a set of exoskeletons even for Yan Guo.

Before the disaster, a variety of exoskeletons have been put into use, not only in the military, but also in the delivery delivery brother.

However, this kind of exoskeleton belongs to passive exoskeleton, which is simply a load-bearing bracket without power source. Through scientific ergonomic design, it can effectively support heavy objects and reduce the physical consumption of users. It is a kind of power assisted device.

However, this kind of exoskeleton obviously can't meet Chen Xin's requirements, and he doesn't need to work hard to develop this kind of thing. The country already has something ready-made to use.

The exoskeleton that Chen Xin wants to develop should be called mechanical exoskeleton or power exoskeleton, which is a kind of mechanical device made of steel frame and can be worn by people. This equipment can provide additional energy for limbs movement.

This kind of equipment is common in all kinds of sci-fi works, such as 50 pieces of good brother's armor in StarCraft, Mark's steel suit in iron man, atongo's suit in tomorrow's edge, ugly T Series in radiation, Spartan's hammer in halo, etc

These are the exoskeletons that people recognize, or more simply, power armor.

In fact, strictly speaking, there is not much difference between the two in essence, or the exoskeleton just lacks more solid protective power armor, while power armor is a more comprehensive exoskeleton.

The concept of this kind of equipment was put forward in the federal government in 1960. After years of research, various related technologies and R & D ideas about exoskeleton have already been proved. What's left is the hard bone that modern science and technology can't solve.

There are two key problems: the first is how to control the exoskeleton in the human-computer interaction mode, and the second is the power source of the exoskeleton.

The choice of human-computer interaction is not a problem in the development of exoskeleton, but it is not so easy to solve.

One of the biggest difficulties in the research and development of exoskeleton is the power source.

In order to solve the problem of power, someone even proposed to make EVA cable powered exoskeleton.

However, these problems are not very difficult for Chen Xin. Take a few steel pipes, weld an active shelf, arrange a mechanical transmission, connect a battery, and even don't need hydraulic assistance. Even if a set of original power exoskeleton is made, the subsequent work can be handed over to the system. Chen Xin just needs to upgrade.

But this is not what Chen Xin wants, or this time, Chen Xin needs to consider more problems and factors.

Because this exoskeleton protective suit is designed for civilian use, it is mainly provided for construction workers and those who need to leave the shelter to work, so as to provide them with warmth and protection in severe cold and harsh environment, as well as a certain degree of help enhancement.

Therefore, this exoskeleton protective clothing mainly focuses on protection and warmth, and it doesn't need to be too strong for power enhancement, and because it is to be mass-produced and put into use, the cost of production and maintenance and the convenience of use should be put in the first place.

It's very easy for Chen Xin to make a set of his own. He can only pile survival without considering the cost. Even if he finally piles up a nano armor like mark85, it's not a problem, but it's only limited to his own use or small batch supply for people in the shelter.

Mass production of exoskeleton protective clothing is not a matter of several sets or dozens of sets, or even hundreds of thousands or millions. There are still hundreds of millions of people in China, even one tenth of them need to use exoskeleton protective clothing, which is also tens of millions of sets. If the cost and maintenance are not taken into account, even countries like China can not afford such a huge burden expenses.

This is the reason why Chen Xin gave up the idea of making full body protective power armor. It's not that he can't make it. It's not that it's too dangerous and not suitable for civilian use. It's that there's no basis for widespread popularization.

In fact, in Chen Xin's idea, such a suit of exoskeleton protective clothing can't even use the miniature isotope thermoelectric battery. It's enough to install a rechargeable battery that can run for dozens of hours. After all, its main function is to keep warm and protect.

It's a good way to keep warm. The pilot's anti-G suit has ready-made technology. Just add resistance wire like electric blanket to make the protective suit have electric heating function. The only problem is whether the battery can bear it.

Moreover, according to Chen Xin's judgment, in the future, this kind of electric heating method will become the main thermal clothing of human beings together with synthetic fiber clothing, because the traditional natural fabrics such as cotton, linen and wool have lost most of the source of raw materials, and even if some of the production capacity can be preserved, it is not for ordinary shelter residents.Therefore, in terms of protective clothing, Chen Xin plans to use one-piece synthetic fiber clothing with electric heating wire to ensure the protective clothing's resistance to cold.

After all, this is a relatively low cost, and more convenient way to obtain raw materials, and also more convenient for production.

In the past, it was difficult to obtain raw materials for duck down and cotton filling to keep warm, so instead of using the filling to keep warm in the past, it was better to directly install electric blanket on the body.

As long as the thermal performance of the outer structure is good enough, the effect of electric heating is good enough, even if the temperature is dozens of degrees below zero, such a suit of exoskeleton protective clothing is enough to ensure that the wearer will not be frostbitten.

In addition, a fully covered helmet connected with oxygen supply equipment is enough to resist the harm of various harmful environments to the wearer.

As for the exoskeleton, it can be relatively simple. It can be based on the relatively mature technology of the existing blind exoskeleton. It can even directly use the blind exoskeleton as the ordinary civil version, and the one with power assisted system can be provided as the upgraded version for the construction workers and other people who need heavy physical labor.

As for the battery part, Chen Xin plans to develop a large capacity and high-performance battery that can be recharged repeatedly as the power source of the exoskeleton protective suit after completing the miniaturization of isotope thermoelectric battery.

On the one hand, exoskeleton protective clothing is a common civilian equipment, which does not need long-term power supply. In addition, isotope thermoelectric battery is radioactive element no matter what, so there will be some safety problems when it is used for civilian use.

On the other hand, due to cost considerations, although the production cost of high-performance battery is not low, it is much lower than that of isotope thermoelectric battery.

Therefore, after comprehensive consideration of various factors, Chen Xinli also has a concept of how to design the exoskeleton protective clothing.

Find out a set of old overalls that he got from his father when he was still working, dig out the electric blanket that can't be used after installing the ground source heat pump, and then go to the warehouse to get the metal materials needed to make exoskeletons. Chen Xin sits in front of the workbench and is ready to make a prototype machine.

With the old work clothes as the main body and the electric blanket as the material, a set of protective clothing with electric heating function was freshly produced after Chen Xin decided to upgrade.

Then you need to install the battery, exoskeleton and helmet.

Among the three batteries, Chen Xin still uses batteries, but this time he is upgrading the batteries to the direction where they can be recharged quickly and repeatedly, rather than making them into highly durable nuclear batteries.

As for the helmet, Chen Xin only plans to make a simplified cover for the time being. Whether to add other functions in the future is a matter of follow-up research and development. As a prototype, it is enough to be able to seal, provide oxygen and shelter the cold outside.
