Description

Artificial cartilage bionic energy-absorbing badminton insole

Technical Field

The utility model belongs to the technical field of insoles, and particularly relates to an artificial cartilage bionic energy-absorbing badminton insole.

Background

In sports, sports equipment of athletes has more and more obvious effects on improving the sports level and protecting the bodies of the athletes, particularly in the comprehensive sports of badminton, the athletes need to run quickly and take off frequently, explosive batting actions and high-load sports in the badminton sports process easily cause joint damage, particularly the conditions of sports damage of ankle joints, knee joints and other parts are very common, meanwhile, three shoe states are outwards turned to a certain degree when the badminton is pedaled and stepped to land, and excessive outwards turning of the rear parts of feet easily causes excessive loads of tendons, muscles and ligaments, so that the lower limbs are damaged. Select proper badminton shoe-pad can play the protection foot in shoes, the vibrations of foot and then the effect of alleviating the impact that the foot received when alleviateing the motion simultaneously.

However, the artificial cartilage bionic energy-absorbing badminton insole in the prior art has poor buffer performance, and cannot effectively reduce impact force generated when a knee joint, an ankle joint and a foot of a sportsman contact the ground when the sportsman lands on a ground by a frequent take-off and stepping method, and meanwhile, the artificial cartilage bionic energy-absorbing badminton insole in the prior art is easy to sideslip, turn over and the like. Moreover, the artificial cartilage bionic energy absorption badminton insole in the prior art is poor in air permeability, and when the artificial cartilage bionic energy absorption badminton insole is worn, the feet feel stuffy and hot, and a suitable environment is easily provided for breeding and propagating bacteria.

Therefore, the artificial cartilage bionic energy-absorbing badminton insole which has excellent buffering performance, lateral slip and outward turning prevention and good air permeability is urgently needed to be designed. The utility model patent ZL201610979730.X discloses a plant oil-based cartilage bionic buffering and damping material, a preparation method and application thereof, and badminton insoles can be developed by the material.

Further, the thickness of the first energy absorption buffer gasket is 2-3 mm; the thickness of the second energy-absorbing buffer gasket is 3-5 mm. In the badminton sports process, the stress of the heel is often higher than that of the half sole, so that the energy-absorbing buffer gaskets on the half sole and the heel of the insole are set to be different in thickness, and the energy-absorbing buffer gasket on the heel of the insole is thicker than that of the half sole of the insole, so that the buffer performance can be ensured, and the comfort level in wearing can also be ensured.

Furthermore, the first energy-absorbing buffer gasket and the second energy-absorbing buffer gasket are both made of polyurethane film-coated foam materials. The energy absorption buffer pad made of the polyurethane film-coated foaming material has the energy absorption effect of 90 percent at most, and achieves the effects of absorbing shock and energy and protecting the foot and knee pad.

Furthermore, the upper surface of the insole body is also provided with an insole surface layer, and the insole surface layer is made of polyester knitted fabric. This dacron looped fabric possesses good air permeability for the heat that the shoe-pad produced can see through in this shoe-pad surface course gives out the external environment.

Further, the insole bottom layer is made of polyurethane foam materials. The bottom layer of the insole adopts polyurethane foam material, which has high hardness and good shaping effect, can avoid fatigue generated by sports to the maximum extent, and can reduce the injury caused by eversion of feet during sports.

Further, the ventilation grooves are of a diamond structure. The arrangement of the air-permeable grooves can not only improve the ground-grasping performance of the insole, but also endow the insole with good air permeability.

Further, the antiskid convex rib is formed by staggering a plurality of straight convex ribs at an angle of 60 degrees. The anti-skid convex ribs are arranged in a staggered mode, so that the insole is attractive and firmer, and the insole and the shoe are combined more tightly.

Furthermore, the middle waist of the insole is raised, and is connected with the half sole of the insole and the heel of the insole to form a wave-shaped structure. Set up the waist into bellied streamlined structure in the shoe-pad, the shape of human foot of laminating just satisfies human engineering and biomechanics' design, has given the splendid travelling comfort of badminton shoe-pad.

Compared with the prior art, the artificial cartilage bionic energy absorption buffer gaskets are arranged on the half sole and the heel of the insole, so that the buffer performance of the badminton insole is greatly improved, and the badminton insole can absorb shock and energy and protect the foot and knee pads; meanwhile, the air-permeable grooves and the anti-skidding convex ribs arranged on the half sole and the middle waist of the insole endow the insole with great friction force, so that the insole is tightly attached to the shoe, the insole cannot shift even if the insole is subjected to long-time severe movement, and the purposes of preventing sideslip and outward turning are achieved.

For a better understanding and practice, the utility model is described in detail below with reference to the accompanying drawings.
