Detailed Description

The present invention will be described in further detail with reference to the drawings and specific embodiments.

As shown in figure 1, the light shock-absorbing leather sole is soft, elastic, shock-absorbing, light and comfortable when walking. The inner bottom 1 of the sole is made of chrome-vegetable combined tanned cattle sole leather, the inner bottom 1 comprises a half sole 2, an arch 3 and a heel part 4, the half sole is in hollowed-out splicing with a shock absorption sheet 5, the heel part is provided with a U-shaped punching slit 6, and a tongue-shaped inner bottom formed by the U-shaped punching slit is filled with a foaming material A8. The chrome-vegetable combined tanned cattle hide leather of the inner bottom 1 is compact, wear-resistant and elastic. The shock absorption sheet 5 is spliced at the half sole of the inner sole 1 in a hollow mode, the shock absorption performance of the leather sole can be improved, and the shock absorption sheet 5 is sewn on the inner sole through threads, so that the shock absorption sheet 5 can be fixed and prevented from moving to other positions when a person walks. The heel of the sole is provided with a U-shaped punched seam 6, and an adjacent foaming material A8 is filled below a tongue-shaped insole 7 formed by the U-shaped punched seam 6, and the adjacent foaming material A8 filled by punching when a person walks generates elastic force like a spring to support the stress of the foot, so that the sole has better elasticity.

The supercritical foaming material is mainly formed by utilizing the physical plasticizing reaction of a supercritical fluid in a special plasticizing pressure container under specific pressure and temperature, and has the characteristics of obvious advantages compared with the material prepared by the traditional foaming technology. The supercritical fluid can be inert gas such as nitrogen or carbon dioxide. The pressurizing device and the heating device are utilized to enable the plasticizing reaction container to reach the required process temperature and pressure. In this case, the gas and the molten raw material are sufficiently and uniformly mixed and diffused by utilizing the specific physical properties of the supercritical gas, and then a mixed state is formed. After the process reaction time is finished, the mixture is extruded out of the mold cavity or the extrusion opening mold, and the pressure drop instantaneously generated by the mixture extrusion of the mold cavity or the extrusion opening mold is utilized, so that the gas is separated out to form a large number of bubble nuclei, and the bubbles continuously grow and are molded in the process of temperature drop, and finally the micropore foaming plastic product is obtained. The supercritical foaming material has the obvious advantages of environmental protection, small product cell size, strong stress structure and light weight, also has the advantages of soft elasticity shock absorption, comfort improvement, portability, sweat absorption, good toughness and the like. The U-shaped punched seam 6 is arranged at the heel part 4 of the sole, so that when a person walks, the super-adjacent foaming material A8 filled below a tongue-shaped inner bottom 7 formed by the U-shaped punched seam 6 generates elasticity to support the stress of the foot along with the rising and falling rhythm of the heel, and the shock absorption effect is achieved. The shock absorption strength of the adjacent foaming material A8 is tested to be 9.98J by filling the lower surface of a tongue-shaped inner bottom 7 formed by the U-shaped punched seam 6.

The shock absorption sheet 5 is made of an ACF (extreme shock absorption material), and the material for manufacturing the shock absorption sheet 5 is low in density, light, nontoxic and tasteless and beneficial to human health due to health considerations. The ACF is a high-molecular high-performance material integrating buffering, shock absorption and energy absorption, simulates the cartilage tissue of a human based on the principle of bionics, and is an artificial cartilage bionic metamaterial with a three-dimensional ultrastructure, which is developed on the basis of interdisciplinary subjects of bionics, mechanics, chemistry, mathematics and the like, and can absorb more than 90% of impact force and instantly convert the impact energy into unobvious heat energy, thereby protecting feet from being damaged to the maximum extent.

The thickness of the shock absorption sheet 5 is 2-4 mm, preferably 3mm, the thickness of the shock absorption sheet 5 is slightly larger than that of the inner bottom 1, so that the thickness of the shock absorption sheet 5 when the shock absorption sheet is pressed to the lowest position when a person walks downwards to exert force is not lower than that of the inner bottom 1, the person walks more comfortably, and the sole part is prevented from pressing against feet. The shape and the size of the shock absorption sheet 5 can be determined according to the requirements of functions and processes, and the change of the shape and the size does not change the core functions of buffering, shock absorption and energy absorption. After improvement, the damping strength of the material of the shock absorption sheet 5 spliced in the hollowed way at the fore sole of the insole is tested to be 6.5J.

The thickness of the over-foaming material A8 filled under the tongue-shaped insole 7 formed by the U-shaped punched seam 6 is 8 to 12mm, preferably 10mm. Because the heel position bears the weight of most people, and is big than the bearing at sole position, consequently, do proper bodiness with the heel of a shoe and can reduce the pressure of motion to the foot, the impact force that the foot received that falls to the ground when buffering people's motion, protection ankle and heel let the motion light more and comfortable.

The arch of foot 3 department is fixed to be set up carbon plate colludes heart 9, can play the effect of support, and then improves the stability of sole. The carbon plate hook core 9 is made of a carbon plate material, the carbon plate is a carbon fiber composite material, the carbon plate is a composite material formed by bonding epoxy resin and carbon fiber yarns through heat treatment, and the carbon plate is a new material with excellent mechanical properties. Its advantages are light weight, high toughness and high strength, and it is a new generation of reinforced fibre. The arch 3 is fixed with the carbon plate hook 9, which replaces the iron sheet material in the prior art, so that the sole has reduced weight and stronger supporting force.

After the cushioning piece 5, the adjacent foaming material A8 and the carbon plate hook core 9 are fixed, the lower surface of the inner bottom is coated with the adjacent foaming material B10, and the thickness of the adjacent foaming material B10 is 3-6 mm, preferably 5mm, so that the soft elastic damping effect of the sole can be further improved. The foot is more comfortable when people walk by the local soft-elastic shock absorption effect generated by the super-adjacent foaming material A8 filled below the tongue-shaped insole 7 formed by the U-shaped punched seam 6 and the shock absorption sheet 5 at the half sole part and the whole soft-elastic shock absorption effect generated by the super-adjacent foaming material B10 attached to the whole sole.

The insole is attached to outsole 11 after being formed.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
