Detailed Description
As shown in fig. 1-4, a hard labour protection toe cap of impact self-adaptation, including sole 3, set up toe cap main part 2 and the vamp 1 of setting in toe cap main part 2 top in sole 3 front end top, the interval sets up first anti-shear zone 21 and lightweight structure district 22 in the toe cap main part 2, vamp 1 includes the crust face 11 on top layer and sets up the second anti-shear zone 12 in the crust face 11 below, first anti-shear zone 21 and second are resisted and are filled shear-thickening fluid in the shear-thickening zone 12, lightweight structure district 22 is for having hollow structure's rubber material.
The shear thickening fluid is normally liquid but when impacted, the shear thickening fluid becomes a hard solid that is difficult to penetrate. When the external impact is removed, the shear thickening fluid returns to a liquid state again.
The hollow structure in lightweight structural zone has good shock resistance and shock-absorbing characteristic, and its synergism with first anti-shear zone can play good shock resistance, protection toe that can be better.
When the shoe toe guard is used, if a heavy object falls to the toe part, the lightweight honeycomb structure of the shoe toe main body and the shear thickening liquid can achieve good impact resistance and energy absorption effects, so that the toe guard can achieve a protection effect. If the heavy object falls to instep vamp region, the vamp can be tightened and inside shearing dope liquid hardens in the twinkling of an eye, and form holistic one, and transmit impact energy to the toe cap main part, substitute for absorption partial energy by the toe cap main part, remaining energy is equallyd divide shear thickening liquid filling area, because shear thickening liquid receives the sclerosis and can form holistic one after assaulting, consequently, the lifting surface area increase of instep, power is shared equally by monoblock shear thickening liquid, consequently, the instep receives pressure less, can effectually protect it.
