Abstract

The utility model discloses a carbon fiber plate, including the carbon plate body, front end profile modeling people's foot sets up the metatarsal district, the metatarsal district is including the first metatarsal district, second metatarsal district, third metatarsal district, fourth metatarsal district and the fifth metatarsal district of alternate segregation. The carbon plate body is designed in five different longitudinal partitions in the metatarsal region, so that the carbon plate body can rebound energy according to different stresses applied by a human body during activities, and accordingly, the steps can obtain larger elastic potential energy and stability when pedaling the ground, and energy loss is reduced.

Description

Carbon fiber plate

Technical Field

The utility model belongs to the technical field of shoemaking, especially, relate to a carbon fiber plate for among military boots.

Background

As a carbon fiber composite material, the carbon fiber plate can ensure the flexibility of the sole, enhance the support and stability of the sole, and particularly prevent the sole from being excessively distorted when a wearer turns to, jumps, runs and the like to a greater degree, thereby improving the protection of the foot. The carbon fiber plate is widely applied to the sports shoe industry and used for improving sports performance in sports shoes, and the application value of the carbon fiber plate in the sports shoe field is designed to strengthen the bottom of the insole of the sports shoes and improve the structural rigidity. The arch of the foot is guaranteed to be stable, anti-torsion protection is provided, and the structure of the carbon plate is mostly in an X shape or a Y shape. The carbon fiber plate is rarely used in the military boots, and the development and research of the carbon plate structure which provides support protection for the antitorque rotation of soldiers so as to prevent sports injury and increase the rebound driving capability of the military boots so as to improve sports performance becomes a hot point of research. It is essential to improve military performance and athletic performance of military personnel during training, prevent athletic injuries during basic training, and improve comfort of wearing military boots.

Chinese patent 2022105773195 discloses a running carbon plate and a preparation method thereof, wherein a metatarsal region of a carbon fiber plate is integrated, a toe region for affecting toes is arranged in front of the metatarsal region, the metatarsal region and the toe region are all integrated, the whole carbon fiber plate is a whole flat plate, and the whole carbon fiber plate is the same as an insole, so that different stress conditions of different parts of a foot during movement and different rebound protection conditions required by the different parts cannot be reflected.

Disclosure of Invention

To the problem that exists among the prior art, the utility model provides a have that well foot area of contact is big, metatarsal region of contact separates subregion, metatarsal resilience is better, stability is stronger, and the carbon fiber plate that energy loss is less and its application in military boots.

The object of the invention is achieved in the following way:

a carbon fiber plate comprises a carbon plate body, wherein the front end of the carbon plate body is provided with a metatarsal region for copying a human foot, and the metatarsal region comprises a first metatarsal region, a second metatarsal region, a third metatarsal region, a fourth metatarsal region and a fifth metatarsal region which are separated from each other.

The back of the carbon plate body is provided with a hollow area.

The middle part of the middle foot on the back of the carbon plate body is provided with a first carbon column.

U-shaped second carbon columns are arranged at the edges of the middle foot and the heel area on the back surface of the carbon plate body.

Compared with the prior art, the utility model has the characteristics of the well foot area of contact is big, the regional separation subregion of metatarsal, metatarsal kick-back is better, stability is stronger, and energy loss is littleer. The design of five different longitudinal partitions of the carbon fiber plate in the metatarsal region can realize the resilience of energy according to different stresses applied by a human body during activity, so that the human body can obtain larger elastic potential energy and stability when kicking off the ground, and the energy loss is reduced.

In the figure, the plate comprises a main body of the 1-carbon plate, a 2-metatarsal region, a 21-first metatarsal region, a 22-second metatarsal region, a 23-third metatarsal region, a 24-fourth metatarsal region, a 25-fifth metatarsal region, a 3-hollowed-out region, 4-carbon columns, 41-first carbon columns and 42-second carbon columns.

Detailed Description

As shown in fig. 1 to 5, a carbon fiber plate comprises a carbon plate body 1, wherein the front end of the carbon plate body 1 is shaped to be a metatarsal region 2 arranged on a human foot, and the metatarsal region 2 comprises a first metatarsal region 21, a second metatarsal region 22, a third metatarsal region 23, a fourth metatarsal region 24 and a fifth metatarsal region 25 which are separated from each other. The design of five different longitudinal partitions of the carbon fiber plate in the metatarsal region can realize the resilience of energy according to different stresses applied by a human body during activity, so that the human body can obtain larger elastic potential energy and stability when kicking off the ground, and the energy loss is reduced.

The hollow-out area 3 is arranged at the back of the carbon plate body 1. The hollow design of the heel area of the carbon fiber plate can increase the comfort of wearing, so that the insole material can better absorb huge ground reaction force borne by the body during human body activities, and better prevent lower limb damage caused by the overlarge ground reaction force.

The middle part of the middle foot on the back of the carbon plate body 1 is provided with a first carbon column 41. The first carbon columns 41 are arranged on the back of the carbon plate body 1 and in the middle of the midfoot, so that the arch position of the shoe is more stable during movement.

The edges of the middle foot and heel area on the back of the carbon plate body 1 are provided with U-shaped second carbon columns 42. The second carbon columns 4 are arranged in the middle foot area and the heel area of the carbon fiber plate, so that the arch position of the shoe is more stable during movement, the mobility of the ankle joint is reduced, and sprain of the ankle joint is reduced. And the carbon fiber has extremely strong toughness, and can ensure that the violent movement cannot be broken or deformed, thereby protecting the feet from being damaged, and the weight of the material is light, so that the burden of movement cannot be increased.

The carbon fiber plate is applied to military boots, and the carbon plate body 1 is arranged in a middle sole of the military boots. The carbon plate body 1 is used for middle sole support and torsion resistance of military boots, and has important significance for improving military performance and sports performance of military personnel during training, preventing sports damage in basic training and improving wearing comfort of the military boots.
