Damping structure with flexible airtight materials wrapping soft foaming materials in sealing mode

Abstract

The invention discloses a damping structure with flexible airtight materials wrapping soft foaming materials in a sealing mode and relates to a damping structure for a shoe, in particular to the damping structure which is made of the soft foaming materials and applicable to a sole. The damping structure with the flexible airtight materials wrapping the soft foam materials in the sealing mode comprises a soft foaming body, wherein a flexible airtight wrapping layer wraps the soft foaming body in a sealing mode, the flexible airtight wrapping layer is made of the airtight materials, and the flexible airtight wrapping layer covers the outer wall of the soft foaming body. According to the structure, the flexible airtight wrapping layer wraps the soft foaming body in the sealing mode, and when external force acts on the soft foaming body, gas which is sealed in cavities formed in the foaming body cannot flow out of the foaming body arranged inside the flexible airtight wrapping layer and can only be compressed. Therefore, the buffering and damping effect is achieved.

Description

technical field [0001] The invention relates to a shock-absorbing structure for shoes, in particular to a shock-absorbing structure for soft foam materials used for shoe soles. Background technique [0002] During people's daily wear and use of shoes, the soles of the shoes should isolate and eliminate the discomfort caused by uneven road surfaces to the soles of the feet, and at the same time protect the soles of the feet from being stabbed by hard objects on the ground during walking. Especially during strenuous exercise such as running and jumping, the arches of the feet, ankles, knees and other joints of the human body will bear huge instantaneous impacts. If the damage to the human body caused by these impacts cannot be effectively alleviated and eliminated, these joints of the human body will be easily damaged. Injured in sports. With the advancement of science and technology and the improvement of human awareness, many new materials and new structures are used in the...

Problems solved by technology

Because this kind of structural shock absorption method pre-sets the gas higher than the atmospheric pressure in the closed cavity, the recovery process of the cavity will be very fast after the external force disappears, but because the built-in air pressure is relatively high, it will In some cases, like an inflated ball, the contact between the sole and the cavity will feel harder, and its comfort is worse than the shock absorption of the aforementioned materials

Moreover, once the cavity wall formed by the resin is damaged and leaks air, the shock absorption ability formed by this structure will be completely lost.
