    Back in the shelter, while Chen Xin was busy miniaturizing the isotope thermoelectric battery, he was also seriously thinking about how to make the exoskeleton protective suit.

    Making an exoskeleton is a very simple matter for Chen Xin. In fact, even for Yan Guo now, making an exoskeleton is not difficult.

    Before the disaster, various exoskeletons that had entered the practical stage were already in use. Not only were they used by the military, but even the delivery boys had experimental exoskeletons.

    ¡° However, this kind of exoskeleton is a passive exoskeleton. Simply put, it is a load-bearing bracket without a power source. Through scientific ergonomic design, it can effectively support heavy objects and reduce the user¡¯s physical exertion. It is a kind of power-assisted device.

    " However, this kind of exoskeleton obviously cannot meet Chen Xin's requirements, and there is no need for him to work hard to develop this kind of thing. The country already has ready-made things that can be used.

    The exoskeleton Chen Xin wants to develop should be called a mechanical exoskeleton or a powered exoskeleton. It is a mechanical device made of a steel frame that can be worn by people. This equipment can provide extra energy for the movement of the limbs.

    This kind of equipment is commonly seen in various science fiction works, such as the fifty-dollar armor in "StarCraft", the Mark series steel suit in "Iron Man", and the armor on Tom Cruise in "Edge of Tomorrow".  A set of equipment, the cute T-series in the "Fallout" series, the Mjolnir of the Spartan warriors in the "Halo" series, etc

    These are the exoskeleton devices that people think of, or more simply, powered armor.

    In fact, strictly speaking, there is not much difference between the two in essence. In other words, the exoskeleton is just a power armor that lacks more solid protection, while the power armor is an exoskeleton with more comprehensive protection.

    The concept of this kind of equipment was proposed in the Federation in 1960. After many years of research, various related technologies and research and development ideas for exoskeletons have long been proven. What is really left is the hard problem that modern technology cannot solve.  .

    There are two most critical issues in this. The first is how to control the exoskeleton in human-computer interaction mode, and the second is the source of power for the exoskeleton.

    The choice of human-computer interaction method in the development of exoskeletons is not a troublesome problem, but it is not an easy problem to solve.

    And the power source is a stumbling block for exoskeletons to enter the practical and promotion stage. It can be said that one of the biggest difficulties in the development of exoskeletons is the problem of power sources.

    In order to solve the power problem, some people have even proposed to make a wired version of the power exoskeleton like EVA that drags a cable.

    However, these problems are actually not difficult for Chen Xin. He can weld a few steel pipes to a movable frame, arrange a mechanical transmission, and connect a battery. He doesn't even need hydraulic assistance. He can just make a set of the most primitive powered exoskeleton.  After it comes out, the rest of the work can be completely handed over to the system. Chen Xin only needs to click on upgrade and it is done.

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

    Because this exoskeleton protective suit is designed for civilian use, it is mainly provided to construction workers and those who need to leave shelters to work outside, providing them with warmth and protection in cold and harsh environments, as well as a certain degree of assistance and enhancement.

    Therefore, this set of exoskeleton protective clothing mainly focuses on protection and warmth. It does not 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 must be put aside.  Considered first.

    It is very simple for Chen Xin to make one by himself. He can just pile up survival points without considering the cost. Even if he finally piles up a nano-armor like mark85, it is not a problem, but this is limited to his own use or small batch supply.  For people in shelters.

    The mass production of exoskeleton protective clothing is not a matter of a few or dozens of sets, or even hundreds of thousands or millions. There are hundreds of millions of people in the country, and even just one in 10 people need to use exoskeleton protective clothing.  There are tens of millions of sets. If the cost and maintenance issues are not considered, even a country like Yanguo cannot afford such a huge expense.

    This is also the reason why Chen Xin gave up the idea of ????developing full-body protective power armor. It is not that it cannot be produced, nor that this thing is too dangerous and not suitable for civilian use, but that there is no basis for widespread popularization.

    In fact, in Chen Xin¡¯s vision, such an exoskeleton protective suit cannot even use the miniaturized isotope thermoelectric battery. Installing one can make it run for dozens of times.An hour's rechargeable battery is enough, after all, its main function is warmth and protection.

    Keeping warm is easy to achieve. There is ready-made technology in the pilot's anti-gravity suit. Just add a resistance wire like an electric blanket to give the protective suit an electric heating function. The only problem is whether the battery can withstand it.

    And according to Chen Xin's judgment, in the future this electric heating method will become the main warm clothing for humans together with synthetic fiber clothing, because traditional natural fabrics, cotton, linen and wool have lost most of their raw material sources. Even if  There is still some production capacity that can be saved, which is not accessible to ordinary shelter residents.

    So for such a set of exoskeleton protective clothing, Chen Xin plans to use one-piece synthetic fiber clothing with electric heating wire for heating to ensure the protective clothing's ability to withstand cold.

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

    In the past, it has become difficult to obtain raw materials for duck down and cotton fillings to keep warm. Therefore, instead of using fillings to keep warm, it is better to directly install electric blankets on the body.

    As long as the thermal insulation performance of the outer structure is good enough and the electric heating method is effective enough, even at low temperatures of tens of degrees below zero, such a set of exoskeleton protective clothing is enough to ensure that the wearer will not suffer frostbite.

    Coupled with a full-coverage helmet connected to oxygen supply equipment, it is enough to resist the harm to the wearer from various harmful environments.

    As for the exoskeleton part, it can be relatively simple. The existing edgeless exoskeleton with relatively mature technology can be used as the basis. You can even directly use the edgeless exoskeleton as an ordinary civilian version, and add a power assist system as an upgraded version for construction.  Workers and other people who require heavy physical labor.

    As for the battery, Chen Xin plans to research a large-capacity high-performance battery that can be recharged repeatedly as the power source for this exoskeleton protective suit after completing the miniaturized isotope thermoelectric battery.

    On the one hand, exoskeleton protective clothing is ordinary civilian equipment and does not require long-term power supply. In addition, isotope thermoelectric batteries are radioactive elements anyway, and there will still be certain safety issues when used for civilian use.

    On the other hand, it is also due to cost considerations. Although the production cost of high-performance batteries is not low, it is still much cheaper than the production of isotope thermoelectric batteries.

    Therefore, after considering all factors, Chen Xin had an idea of ??how to design this exoskeleton protective suit.

    I found a set of old work clothes that I got from my father when I was still working, dug out an electric blanket that was no longer useful after installing a geothermal heat pump, and then went to the warehouse to get the necessary materials for making an exoskeleton.  Using metal materials, Chen Xin sat down at the workbench, preparing to make a prototype first.

    Using old work clothes as the main body and adding electric blankets as materials, a set of protective clothing with electric heating function was newly released after Chen Xin decided to upgrade.

    After that all that needs to be installed is the battery, exoskeleton and helmet.

    Among the three, Chen Xin still uses storage batteries, but this time he upgraded the storage battery to one that can be quickly and repeatedly charged, instead of making it a highly durable nuclear battery.

    As for the helmet, Chen Xin only plans to make a simple version of the cover for the time being. As for whether to add other functions in the future, it is a matter of subsequent research and development. As a prototype, it is enough to be able to seal, provide oxygen and block the cold outside.  (Remember the website address: www.hlnovel.com
