Abstract
The invention discloses a nano-porous energy absorption device and belongs to the field of nano-technologies. The device can be used for effectively absorbing energy generated by collision of an object, so that the harm to a human body caused by the collision is reduced. The nano-porous energy absorption device structurally comprises a nano-porous material and a fluid, wherein the nano-porous material and the fluid are arranged in an inclusion. The nano-porous energy absorption device is applicable to various fields; according to different system work conditions, the system performance can be flexibly adjusted, and the energy absorption effect is obvious.
Description
Technical field
The invention belongs to nanosecond science and technology field, relate to a kind of energy absorbing device, especially a kind of nanoporous energy absorbing device.
Background technique
In recent years, due to the sharp increase of various vehicles numbers, road traffic accident takes place frequently.When accident occurs, the mutual impact moment of car body can produce very large energy.At present, the energy part that collision produces is converted into the flow of metal of car body memory-type, and another part energy causes directly or indirect infringement human body, and the infringement that the energy that traffic accident produces causes human body is difficult to estimate.
Existing body of motor vehicle or some energy absorption device, major part is all to take traditional material as main, and such as composite material, porous metals, foamed material, marmem, the energy-absorbing effect of these materials is limited, and this is to be determined by their structures own.
Nanosecond science and technology are the very fast new technology of development in recent years, be widely used, and it have produced extremely important impact to a lot of fields in a plurality of fields such as traditional material, medical equipment, electronic equipment, coating.Wherein, nano-porous materials is an important subject in nanosecond science and technology, because it has very large specific surface area, thereby is widely used.
Summary of the invention
Technical assignment of the present invention is to provide a kind of nanoporous energy absorbing device for above-mentioned deficiency of the prior art, and the energy that this device produces in the time of can effectively absorbing object collision has reduced the infringement that collision causes human body.
The technical solution adopted for the present invention to solve the technical problems is: this kind of nanoporous energy absorbing device, it is characterized in that, and its structure comprises nano-porous materials and fluid, described nano-porous materials and fluid are placed in an inclusion.
Optionally, described nano-porous materials is one or more in zeolite, nano-stephanoporate silicon dioxide, aluminium oxide, zine oxide, titanium dioxide, Au, Cu, PMMA, carbon nano-tube.
Optionally, described fluid is deionized water, alcohol water mixed solvent or alkaline solution.
Optionally, the geometric figure that described inclusion is airtight.
The present invention has following outstanding beneficial effect:
1, because its structure comprises nano-porous materials and fluid, described nano-porous materials and fluid are placed in an inclusion, so this device is when being subject to External Force Acting, the Conversion of Energy that nano-porous materials and fluid can produce collision is interface energy and heat energy, effectively absorbed most of energy, the less significantly infringement to human body.
2, the cost of raw material of the present invention is cheap, has reduced
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present invention.
Accompanying drawing 2 is power absorption schematic diagram of the present invention.
Description of reference numerals: 1 inclusion, 2 nano-porous materials, 3 fluids.
Embodiment
As shown in Figure 1, this kind of nanoporous energy absorbing device, its structure comprises nano-porous materials 2 and fluid 3, described nano-porous materials 2 and fluid 3 are placed in an inclusion 1.
Optionally, described nano-porous materials 2 is one or more in zeolite, nano-stephanoporate silicon dioxide, aluminium oxide, zine oxide, titanium dioxide, Au, Cu, PMMA, carbon nano-tube, can be according to different applications, select different nano-porous materials, to reach best energy-absorbing effect.
Optionally, described fluid 3 is deionized water, alcohol water mixed solvent or alkaline solution, can configure corresponding fluid according to selected nano-porous materials, to reach best energy-absorbing effect.
Optionally, the described airtight geometric figure of inclusion 1, can be made into different shapes according to different applied environments, do not affect using effect, inclusion can be removed if desired, is directly filled in desired structure.
When bumping, first external force start effect to inclusion, and then being applied to fluid, fluid can enter into the hole of nano-porous materials under external force, first needs to overcome capillary force, to change part external work into solid liquid interface energy, secondly, in fluid transport process, need to overcome stickiness power, namely frictional force, changes heat energy into part external work.
Fig. 2 is power absorption schematic diagram of the present invention, as shown in the figure, and the part that two curves and X-axis the are surrounded energy that this device absorbs.The energy absorption efficiency of this device in very large range can change, and this is relevant with the idiosyncratic behavior of fluid molecule under nanometer constraint environment.Because nano-porous materials itself has huge specific surface area, so it provides a desirable transformation of energy platform, makes the novel energy conversion device that has great potential of being combined into of nano-porous materials and fluid.
Nanoporous energy absorbing device of the present invention, from existing shear thickening liquid is different on the market, nanoporous liquid is directly worked under pressure, installs simplicity of design and can absorb much more energy, can be filled directly in a lot of existing structures.The flexibility of liquid makes its application space unrestricted.Can under multiple operating conditions, apply, comprise low speed and high speed impact, such as shoe-pad and joint protecting, lancination, motorcycle and sports helmet, car crash, bullet impact, blast etc.According to different system operating mode, systematic function can free adjusting.
The above, be only preferred embodiment of the present invention, not the present invention done to any pro forma restriction.Any those of ordinary skill in the art, are not departing from technical solution of the present invention scope situation, all can utilize technology contents described above to make many possible changes and modification to technical solution of the present invention, or be revised as the equivalent embodiment of equivalent variations.Therefore, every content that does not depart from technical solution of the present invention, to any change modification made for any of the above embodiments, equivalent variations and modification, all belongs to the protection domain of the technical program according to technology of the present invention.
