Description

Bionic insole with cushioning and supporting functions

Technical Field

The utility model belongs to the technical field of the engineering is bionical, concretely relates to have bionical shoes insole that bradyseism and support function concurrently according to inside buffer material of the sole foot pad of metatarsophalangeal joint motion gesture and third toe when ostrich foot contacts to earth.

Background

When a person moves, due to the cushioning performance of the sole, the impact force of the ground on the human body is effectively buffered, so that the yielding work of the muscle groups of the lower limbs is properly reduced, and the lower limbs are protected. The sole consists of three parts, namely an insole, a midsole and an outsole, and the core of the cushioning technology of the sole is the midsole. Most of the existing cushioning designs focus on cushioning in the heel area, but the front sole part of the sole has great influence on running, jumping and other movements, and the important consideration should be given in the future. The existing shoe cushioning mainly starts from materials and structures, and adopts a midsole material with the cushioning performance or a special physical structure to deform, absorb energy and cushion. The shock absorption of a pure material cannot respond to the impact of high frequency, and the problems of durability and service life of the material exist; the stability and the support of the pure structure cushioning have certain defects. Therefore, the sole becomes an effective means from the perspective of structure and material coupling in a limited midsole thickness space, especially a thinner forefoot, and can effectively cushion shock and simultaneously keep the sole stably supported.

Animals in nature evolve superior structures or functions in long-term evolution, and can be applied to the fields related to human beings. The adult African ostrich can keep the speed of about 55km/h under the weight of more than 150kg, can continuously run for more than 30min, and can run under the high-speed heavy load with huge ground impact force, and the foot is not damaged particularly, and the cushioning performance of the ostrich foot is undoubtedly superior as the foot which is in direct contact with the ground. It has been found and proved by studies that the ostrich can be deformed to offset the large impact force when touching the ground by covering the thick foot pad under the toes of the foot. Moreover, the unique structure of the ostrich foot, particularly the structure characteristics and the motion posture of the metatarsophalangeal joint, also plays a role in buffering and damping.

Disclosure of Invention

The utility model provides a bionical shoes bradyseism insole of structure and material coupling, from the high-speed heavy load condition of ostrich under, and ostrich low limbs especially foot is not damaged and is obtained the inspiration, based on ostrich foot bradyseism mechanism, adopt engineering bionics principle, with ostrich foot metatarsophalangeal joint structural feature and third toe foot pad material and structure equipment characteristic application bionically bradyseism insole design, can effectively promote the bradyseism performance of shoes, and stabilize human foot and reduce the injury probability, realize the unity of sole bradyseism and stable support.

The utility model relates to a train of thought comes from the motion gesture of ostrich foot and the foot pad of third toe, and the sole toe joint structural feature and third toe foot pad material assemble the characteristic with the structure, design bionical bradyseism shoes insole.
