Description

TPU arcuation fretwork motion sole of adopting structure bradyseism

Technical Field

The utility model relates to a motion equipment field specifically is an adopt TPU arcuation fretwork motion sole of structure bradyseism.

Background

The commonly used sports shoe sole cushioning mode in the market is material cushioning, and currently, air cushion insoles are adopted for cushioning, or various thermoplastic elastomers such as EVA, TPR, SBS and the like are used. The insole is made of special rebound force materials, so that part of the reaction force can be effectively absorbed, the burden of the foot is reduced, and the insole is easier and more comfortable to wear; the air bag rubber is used for storing air in the air cushion to provide elasticity and reducing vibration during sports, and the air cushion is designed to relieve the vibration caused by impact between ankles and the ground during daily walking and also can provide additional shock absorption and bearing force; the EVA has low crystallinity, high flexibility, high impact resistance, high filler intermiscibility and high heat sealing performance owing to the introduction of vinyl acetate monomer into the molecular chain, and is widely used in foamed shoe material.

Mechanical cushioning utilizes mechanical structure design to realize the technique of bradyseism, through unique insole structure, utilizes TPU (thermoplastic polyurethane elastomer rubber) to reach the bradyseism effect, also is called structural bradyseism. Compared with the material cushioning which realizes cushioning by means of the elasticity of the soft material, the material cushioning device is not easy to collapse, deform and the like due to the time lapse, thereby avoiding weakening and losing of the cushioning effect. In combination, the cushioning material has a longer useful life and stability than the cushioning material does in compression and rebound. Therefore, in view of the above current situation, there is an urgent need to develop a TPU arc-shaped hollowed-out sports shoe sole with a shock absorption structure to overcome the shortcomings in the current practical application.

Detailed Description

The technical solution of the present patent will be described in further detail with reference to the following embodiments.

Reference will now be made in detail to embodiments of the present patent, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present patent and are not to be construed as limiting the present patent.

Example 1

Referring to fig. 1-2, in an embodiment of the present invention, a TPU arc-shaped hollowed-out sports shoe sole with a shock absorption structure includes a shoe body 1 and a shoe sole 2 disposed at the bottom of the shoe body 1 in a matching manner, where the shoe sole 2 includes an arch support ring 21 and a bottom plate 22, the upper side of the bottom plate 22 is sequentially and alternately arranged with a plurality of arch support rings 21 (the arch structure is a common force-bearing shock-absorbing structure in life, the arch structure is a curved or zigzag member mainly bearing axial pressure and maintaining balance by thrust at both ends, the supports at both ends generate horizontal thrust under vertical load, and under the thrust, the arch cross-section bending moment is reduced, so that the arch mainly bears axial pressure, and particularly when bearing full-span load, the arch structure has high rigidity and bearing capacity, the axial force and bending moment are symmetrically distributed, so that pressure from the top can be uniformly dispersed to both sides of arch legs, the vertical pressure is transferred down through deformation of the supports, and then the arch support rings 21 and the bottom plate 22 are restored to form an integral injection molding, the arch support rings 21 are semi-circular structure, and two lower ends of the arch support rings 21 are fixed to the adjacent bottom plate L, and the distance between the two adjacent arch support rings is a 3624.

Further, the sole 2 is made of TPU materials, so that the sole can be deformed, cushioned and decompressed under stress, and the shape can be restored by utilizing the hardness of the sole.

The utility model discloses elasticity law based on structural mechanics uses arch support ring 21 to realize bradyseism decompression function in the design, uses several arch support ring 21 staggered arrangement in proper order, can strengthen its functionality on the one hand by a wide margin, and on the other hand also saves the preparation raw materials, reduces its cost of manufacture, reaches more economic purpose, and hollow out construction can alleviate the weight of sole 2 simultaneously, reinforcing comfort of wearing.
