Description

Sole with magnetic hydraulic damping system

Technical Field

The invention relates to the technical field of sports shoe cushioning, in particular to a sole with a magnetic hydraulic damping system.

Background

Sports damping has long been a highly appreciated problem in sports. When a person runs, the impact force of the ground at the moment when the foot touches the ground reaches 2-3 times of the weight of the human body, and the impact force born by fast running is 3-4 times of the impact force born by slow running.

Bones, ligaments, tendons and the like of a human foot form a natural buffering and shock absorbing structure, namely the arch of the foot, but the force which can be borne by the arch of the foot is limited. If the sports shoes do not have good shock absorption systems to relieve the force, both feet feel tired, achilles tendon strain, triangular ligament strain, gastrocnemius ligament rupture, acute knee joint swelling and other symptoms can be caused seriously, impact force generated when the feet touch the ground every time is transmitted to all parts of a human body along with bones, and the brain and internal organs of the human body can be injured after long-term accumulation, so that cerebral concussion and other diseases can be caused. In order to better increase the motion buffer, reduce the pressure of ankles and joints of athletes and avoid the motion injury, the good shock absorption function can ensure that the weight of a human body is more evenly distributed on soles of the feet, and the motion injury is reduced.

Based on the background, the invention designs a magnetic hydraulic damping system for sports shoes by applying a magnetic technology and a liquid damping technology.

Detailed description of the preferred embodiments

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1 to 3, the magnetic hydraulic damping system for sports shoes of the present embodiment includes an outsole 1 and a midsole 2, the midsole 2 has a U-shaped cavity 3 corresponding to a heel portion of a rear sole, the U-shaped cavity 3 is wrapped by a damping airbag 4 to form an air-tight chamber, a damping device 5 is disposed in the air-tight chamber, the damping device 5 is formed by connecting 8 hexagonal prism members 6 in a honeycomb manner, and since the hexagonal structure of the honeycomb is the most compact structure, each side is equally stressed, and the honeycomb structure is easily dispersed in stress under a fixed volume, the minimum surface area and the maximum tightness can be provided, and the required material is the least. When the shock-absorbing member is used as a shock-absorbing member, the force applied in all directions is basically equal, the material consumption is small, the weight is light, the cost is low, and the sufficient impact resistance and the buffer property can be ensured. The hexagonal prism component 6 is integrally made of a high-elasticity PU foaming material, and the microporous PU elastomer has the characteristics of light weight, wear resistance, folding resistance, oil resistance, chemical resistance and the like, is soft in foot feel, comfortable to wear, warm-keeping, high in elasticity and skid-proof. The outward turning phenomenon of human foot generally makes the outer sole bear larger force, and the support column 8 protruded from the outer side of the hexagonal prism member 6 can bear the force, so as to provide strong elasticity and comprehensive protection for the wearer. A strong Nd-Fe-B magnet 12 with the weight of about 10g is respectively arranged on the upper part and the lower part of each hexagonal prism component 6, and the magnetic field repulsion force between permanent magnets is used as an elastic medium to provide shock absorption, so that the shock absorption can replace or assist the air cushion type shock absorption of the sports shoes which are commonly used at present. In addition, according to the traditional Chinese medicine magnetic therapy principle, the stable and uniform magnetic field of the neodymium iron boron magnet 12 can also promote blood circulation of a human body, relieve muscle soreness and have certain medical care effects. The hexagonal prism component 6 is filled with HL32 hydraulic oil in the cylindrical cavity 7 (the curved surface has better bending resistance and can prevent the outer wall from being crushed by overlarge pressure of liquid), and the huge impact force generated when a person jumps up and lands on the ground is transferred to the outer wall of the damping device to cause deformation by applying a hydraulic damping principle, so that the stress time is prolonged, the huge impact force generated during falling can be transferred to the outer wall of the hexagonal prism component 6 to cause deformation of the outer wall, and the impact force is converted into upward feedback force. The outer surface of the hexagonal prism component 6 is coated with a layer of PVC material to prevent hydraulic oil from leaking, and the cylindrical cavities 7 in the middle of the 8 hexagonal prism components 6 are communicated with each other through the annular flow guide pipe 12, so that the interiors of the 8 hexagonal prism components 6 are connected into a whole, and the hydraulic oil can flow to a required position according to stress during movement, and further, ground adaptability and a damping function are provided. The bearing plate 14 is composed of an inner part and an outer part, the connecting part of the bearing plate inner part 11 and the hexagonal prism component 6 is made of high-elasticity PU materials and is integrally manufactured with the cylindrical component of the hexagonal prism component 6, and the bearing plate is tightly matched with the hexagonal prism component 6, so that the pressure of the heel can be absorbed and recombined, and the collected energy is stored in a centralized way and released upwards. The joint of the outer part 13 of the supporting plate and the insole 2 is made of a high-strength carbon fiber material plate so as to strengthen the heel of the shoe and reduce the probability of foot injury.
