Abstract
The invention discloses a protection pad. The protection pad comprises at least an absorbing energy layer made of aerogel. The absorbing energy layer assimilates and dissipates impact energy through two mechanisms: 1. the breakage of porous skeleton in the process of pressing material. The aerogel comprises mesoscale and nanoscale micro porous requiring sufficiently strong energy to be destroyed. The breakage of the skeleton is irreversible. 2. The air release of the micro porous. The air in the micro porous of aerogel needs to be released through the process of the pressing, but the release is hindered by the aerogel skeleton, which produces the rapids of the mesoscale. And then the kinetic energy turns into the heat energy. The collision energy is fully absorbed from the two above mentioned mechanisms. The absorbed energy is not released back into the air which ensures no further damage to the human body. Based on above foundation, the invention provides a helmet and a kneecap.
Description
Technical field
The present invention relates to sports goods, more particularly to a kind of protection pad, the helmet and knee-pad.
Background technology
The protection pad of the protector of sports at present uses expanded polystyrene (Expanded Polystyrene) or expansion
Polystyrene (Expanded Propylene), or other types of organic foam is used as impact energy absorption layer.
One of this protection pad has the disadvantage the not good energy-absorbing material of these materials.That is, the energy of their absorptions
Amount much all can be discharged again, is given people body and is caused further injury.
The content of the invention
It is an object of the invention to provide a kind of protection pad, the helmet and knee-pad, to solve existing body present in prior art
Educate the not good technical problem of the protection pad energy absorption capacity of protecting ware for sports.
The protection pad that the present invention is provided, the protection pad includes the absorbing energy layer at least by made by aeroge.
Further, the aeroge is the compound of organic aerogel, inorganic aerogels or both.
Further, running through in the absorbing energy layer has reinforcing fiber.
Reinforcing fiber exists for human body there is provided further protection, and expanded polystyrene or expansion polystyrene
Deng foamed material typically get along well reinforcing fiber be combined.
Further, the reinforcing fiber is glass fibre, carbon fiber, aramid fiber or high molecular weight polyethylene fiber.
Further, the protection pad also includes the cushion connected as one with the absorbing energy layer.
Further, the cushion is foamed buffer layer.
Absorbing energy layer can be used in conjunction with foamed buffer layer.
Foamed buffer layer provides the protection under the impact of O-level, and aeroge absorbing energy layer can be in bigger shock
Under power, energy-absorbing protection is provided when human body can come to harm, this is because aeroge absorbing energy layer elasticity is not good, in O-level
Impact under provide protection be not so good as existing foamed buffer layer.
The protection pad that the present invention is provided, has the advantage that：
Absorbing energy layer absorbs and digests Impact energy by two kinds of mechanism at least by made by aeroge：
1. the destruction of porous skeleton during material is flattened.

Destruction it is irreversible.
2. the release of micro porous hollow gas.
In compression process, the air in aeroge micropore needs to be released, but this release is by aeroge skeleton
Hinder, this generates the turbulent flow of micro-scale, kinetic energy when clashing into is converted into into heat energy.
The energy of collision is fully absorbed by above two mechanism, and the energy for absorbing will not be discharged again,
Further injury will not be caused to human body.
The species of the aeroge used by protection pad, density, thickness can be adjusted according to actual needs, the body in different products
Existing different energy absorption characteristics.
There is the impact born during irreversible breaking in aeroge, it should more than the impact of O-level, and be less than people
Impact when body can come to harm, this is because endergonic process is irreversible, so should not hitting in O-level
Hit under power and be destroyed.
In addition, present invention also offers a kind of helmet, including shell, liner and above-mentioned protection pad, the liner is arranged
In the enclosure, the absorbing energy layer is arranged between the shell and the liner.
The helmet that the present invention is provided, has the advantage that：
Using the helmet of protection pad of the present invention, energy-absorbing protection during collision is provided for human body.
In addition, present invention also offers a kind of knee-pad, including flame retarded rigid plate, flame-retardant foam layer, flame-retardant textile, frenulum with
And above-mentioned protection pad, the flame retarded rigid plate in shield shape and on the flame-retardant textile, the flame retarded rigid plate and institute
State between flame-retardant textile that respectively device has absorbing energy layer and flame-retardant foam layer, the frenulum is separately positioned on the flame-retardant textile two
End.
Further, the flame-retardant foam layer is the eva foam for adding fire retardant.
Further, the flame-retardant textile is the fire-retardant oxford of terylene coating.
The knee-pad that the present invention is provided, has the advantage that：
The knee-pad that the present invention is provided, energy-absorbing protection during collision is provided for human body, when using as fireman's knee-pad, is needed
To use the good inorganic aerogels of high temperature resistant, non-combustible, heat-proof quality, such as aerosil.Some organic airsettings
Glue, such as polyimide aerogels, it is also possible to which more than 300 degrees Celsius of temperature tolerance and thermal insulation at high temperature are provided, so that
Also have the advantages that high temperature resistant, non-combustible, heat-proof quality are good when knee-pad is used as fireman's knee-pad.
