Title:
HIGH ENERGY STORAGE SOLE BASED ON HOLLOW HIGH-ELASTICITY STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2023/044943
Kind Code:
A1
Abstract:
A high energy storage sole based on a hollow high-elasticity structure, relating to the field of shoe soles. The sole comprises a topsole (1), a midsole (2) and an outsole (3), sequentially arranged from top to bottom. The topsole (1) and the midsole (2) are detachably connected, multiple through holes (4) in communication with each other are symmetrically arranged on two sides of the bottom of the outsole (3), and a first elastic energy storage apparatus is disposed between the midsole (2) and the outsole (3) at a position corresponding to the heel. The first elastic energy storage apparatus comprises an airbag ball (5) fixedly penetrating through the heel of the midsole (2), one-way air valves being disposed at both sides of the airbag ball (5), and an air outlet pipe (6) and an air inlet pipe (7) being arranged at two sides of the airbag ball (5), so that air outside the sole can pass through a first air channel (11) and the air inlet pipe (7) under the action of a fan (12) and negative pressure to instantaneously fill the airbag ball (5). In the instantaneous filling process, the airbag ball (5) instantaeously generates high elasticity at the heel. And, by means of the airbag ball (5), the air outlet pipe (6), a mounting groove and two first air channels (11), a cyclic high energy storage system is formed at the heel of the sole.
