Embodiment
Embodiments of the invention are described below in detail, the example of the embodiment is shown in the drawings, wherein from beginning to end
Same or similar label represents same or similar element or the element with same or like function.Below with reference to attached
The embodiment of figure description is exemplary, is only used for explaining the present invention, and is not construed as limiting the claims.
Fig. 1 is the explosive view of the specific embodiment of the invention；Fig. 2 is the structural representation of the specific embodiment of the invention；
Fig. 3 is Fig. 2 upward view；Fig. 4 is the structural representation of the pull bar of the specific embodiment of the invention.
Fig. 1 to Fig. 4 is refer to, the embodiments of the invention provide a kind of safety belt tight receiving apparatus automatically, wherein, including tank body
1st, pull bar 2, safe carrying spigots 3, non-newtonian fluid and leakproof oil ring 5；
The tank body 1 is arranged on vehicle, and the first end of the tank body 1 seals the second end and is provided with circular open 6, the non newtonian
Fluid is in the tank body 1；The first end of the pull bar 2 is provided with the blade 7 of multi-disc dentation, and the first end of the pull bar 2 can
It is slidably mounted in the tank body 1, the second end of the pull bar 2 passes through the opening 6；The leakproof oil ring 5 is arranged on institute
State at opening 6, the second end of the pull bar 2 is connected with the safe carrying spigots 3.
The operation principle of the device is：The viscosity of non-Newtonian fluid raises with the increase of shear rate（Referred to as shear force
Thickening behavior）, such as fluid is expanded, its viscosity increases with the increase of detrusion speed.Its constitutive equation is, wherein, τ
It is shear stress, K is modulus index, and n is power law index, n>1, it is detrusion speed：Namely ribbon by transmission device,
Band movable vane piece 7 moves, when blade 7 drives flow of fluid, the current gradient in perpendicular flow direction.When it is implemented, sent out in vehicle
When giving birth to huge shock, human body pulls rapidly safety belt, and safety belt pulls pull bar 2 to move rapidly by safe carrying spigots 3, pull bar
The fly-cutting non-newtonian fluid of blade 7 of multi-disc dentation during 2 movements on pull bar 2, make what non-newtonian fluid was subject to cut
Cutting speed degree abruptly increase, the viscosity of the fluid can abruptly increase, what the enhancing of viscosity was brought is the enhancing of the intensity of non-newtonian fluid, its intensity
Even it is enough the elongation for preventing ribbon comparable to the hardness of solid matter, this intensity, personnel is fixed on seat, reaches protection
Purpose, hit and recover the soft characteristic of its fluid after terminating, reach the purpose that protection human body fragility organ will not come to harm.
As a kind of preferred embodiment, spring 8 is still further comprised, the spring 8 is arranged in the tank body 1, the bullet
