Ester material, foamed aluminium etc. absorb energy by space large deformation, and energy-absorbing density is smaller, and can not restore after deforming, maintenance dimension
It is larger to repair expense.It is badly in need of a kind of Energy dissipating material or structure that there can be energy-absorbing density greatly and there is sub- recovery capability, to meet
High speed impact acts on the requirement of the lower big energy consumption of small deformation.
Summary of the invention
The purpose of the utility model is to provide a kind of anti-collision energy absorption structures, special based on the unique energy-absorbing of nano-fluid material
Sign plays the effect for slowing down impact, absorbing energy, reducing active force, makes to prevent safely as the accessory structure of security protection product
Shield product preferably plays protective action.
The technology employed by the present utility model is
A kind of anti-collision energy absorption structure, it is characterised in that:
The anti-collision energy absorption structure includes flexible shell fixed above flexible bottom and flexible bottom, inside flexible shell
Filled with energy consumption core material, rigid upper plate is fixed at the top of flexible shell.
Flexible bottom surface is provided with protrusion, and flexible shell bottom surface is correspondingly arranged fluted, the protrusion insertion of flexible bottom
In the groove of flexible shell, contact surface is fixedly connected by adhesive means.
The flexible shell periphery on flexible bottom surface is provided with cricoid flanged plate, and flanged plate and flexible bottom offer pair
Anti-collision energy absorption structure integral installation is fixed to by fender surface by the screw hole answered by bolt.
Flexible bottom is rubber material.
Flexible shell is rubber material.
Energy consumption core material is nano-fluid material.
Rigid upper plate both ends are folded upward to form the C-shaped stereochemical structure in cross section.
Flexible shell top surface is provided with pre-embedded steel slab, and nut is welded on pre-embedded steel slab, is correspondingly arranged on rigid upper plate
There is screw hole, rigid upper plate is fixed on flexible shell top surface by screw and nut.
The utility model has the advantage that
(1) have good energy-absorbing effect:
Use nano-fluid for main energy-absorbing material, when impact force is transferred to structure, extraneous kinetic energy is in huge nanometer
It dissipates in porous material-liquid surface, mechanical energy is converted into solid-fluid interface energy and frictional heat energy, is truly realized energy
Conservation conversion is measured, which, which absorbs density, can achieve 60-200J/g, there is the energy-absorbing effect that traditional material is incomparable.
(2) recoverability after hitting:
When shock, functional liquid is pressurized, and flows into nano pore, and structure both shrinks will hit generation energy and be converted into fluid fortune
Kinetic energy；After impact force is cancelled, functional liquid will flow out nano pore, and therefore, deformation can restore after shock, and product can be repeatedly more
Secondary use.
(3) the simple and practical property of form is strong:
The form that structure is connected by screw bolts, structure is simple, easy for installation, and readily replaceable, strong applicability.
