Description

Running shoe with composite damping structure

Technical Field

The utility model relates to the field of sports shoes, in particular to a running shoe which is provided with a plurality of different shock absorption areas at the bottom of a shoe to realize composite shock absorption and further better meet the requirement of protecting feet in running sports.

Background

With the continuous development of economy, the living of people has the change of natural and overturning land, and most people can release pressure and enjoy physical and mental health in a jogging mode. However, jogging exercise has strict requirements on protection, the lower limbs of a human body are easily damaged in a overstraining way in the exercise process, and the human body is easily subjected to falling impact force in the jogging process.

Specifically, the sole of the foot of a human body is subjected to a pressure higher than that of walking under the exercise state, and in order to reduce damage caused by impact force during jogging, the foot naturally turns outwards appropriately to absorb a part of impact force after falling to the ground, but if the foot turns over excessively, damage or deformation of the foot can be caused. The metatarsal region of the front sole of the foot is required to bear the self-mass and exert force to push the ground, so that the pressure is the largest, the inner side and the outer side of the heel bear most of impulsive force in the landing stage, and the impact force and the acting force of the metatarsal region are relatively small. The degree of foot rollover from ground to support during jogging is likely to exceed the normal range, and it is therefore necessary to design the footwear cushioning structure specifically for the running activity.

The existing running shoes only focus on the damping design of the heel part, and have the defects of simple damping structure, poor damping performance and larger improvement space and requirement.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the defects in the prior art and provide running shoes with composite shock absorption structures.

In order to achieve the purpose, the technical scheme adopted by the utility model is as follows: a running shoe with a composite damping structure comprises a sole and a vamp, wherein the sole consists of an outsole and a midsole with the composite damping structure, the midsole is respectively provided with an EVA layer, a damping layer and an ETPU layer from top to bottom, and the damping layer is clamped between the EVA layer and the ETPU layer to form a three-layer hamburger type structure; the shock absorption layer consists of a front shock absorption unit and a rear shock absorption unit; the front shock absorption unit is used for shock absorption of a sole and is formed by integrally bonding three horizontal columnar air bags which are designed to extend along the longitudinal axis direction of the sole; the rear shock absorption unit consists of a horizontal wave shock absorption sheet which extends along the transverse direction of the sole and two rubber sheets which are matched with the upper surface and the lower surface of the horizontal wave shock absorption sheet; the two rubber sheets are respectively adhered and fixed with the EVA layer and the ETPU layer.

Furthermore, a plurality of vent holes are formed in the EVA layer.

Furthermore, the transverse length ratio of the front shock absorption unit to the rear shock absorption unit is 1:3, and the front shock absorption unit and the rear shock absorption unit are isolated by an EVA block.

Further, the three horizontal columnar air bags in the front shock absorption unit are respectively filled with 0.8, 0.9 and 1 atmospheric pressure of nitrogen from front to back.

Further, the wave shape of the horizontal wave damper is nonlinear, and the interval between the wave-shaped convexes and concaves becomes smaller from front to back.

When the utility model is implemented, the front and the rear shock absorption areas are formed, and the shock absorption properties of different positions in the front and the rear shock absorption areas are different, thereby better adapting to the actual shock absorption requirements of each part of the foot during running.
