[0031] Reference Signs List Figures 1-9The embodiment provides a kind of air pressure power shock-absorbing rebound component, including the power cabin 4 being arranged corresponding to the position of rear sole of foot, the power cabin 4 is connected with transducer cabin 3, transducer cabin 3 is located in front side of heel;Air guide channel 2 is connected in the transducer cabin 3 being provided with air guide piece 6 in the transducer cabin 3, one end of the air guide piece 6 extends and is penetrated into the power cabin 4, the other end extends and is penetrated into air guide channel 2, and air guide piece 6 is tightly filled in the hole of the power cabin 4 and the transducer cabin 3 connected with the hole of the transducer cabin 3 and air guide channel 2 connected, and is the only air communication path between the two, so that the power cabin 4 is only air communicated with transducer cabin 3 by air guide piece 6, the transducer cabin 3 is only air communicated with air guide channel 2 by air guide piece 6.The end of the air guide channel 2 is connected with the air cabin 1 corresponding to the position of front sole of foot, the power cabin 4, transducer cabin 3, air cabin 1 are flexible chamber.The air guide channel 2 is flexible airway, and the two ends are respectively connected with one end of the air cabin 1 and one end of the transducer cabin 3.The air cabin 1, air guide channel 2 are made of relatively soft TPU film, and the power cabin 4, transducer cabin 3 are made of high-hardness TPU film.
[0032] The air guide piece 6 includes mutually connected rapid flow section 60 and slow flow section 61, the width b of the rapid flow section 60 is narrower than the width a of the slow flow section 61, the rapid flow section 60 and the slow flow section 61 are integrated structure, and the junction of the rapid flow section 60 and the slow flow section 61 is provided with smooth inclined transition section 62. Wherein, the width ratio b:a of the rapid flow section 60 and the slow flow section 61 is 1:1.5 to 1:3. In the embodiment, the length ratio of the rapid flow section 60 and the slow flow section 61 is 1:1, and the width ratio b:a is 1:2, which is suitable for fast walking and slow running. In other embodiments, the width ratio b:a is 1:2.5 or 1:3, which is suitable for high-intensity sports such as basketball and long-distance running, and the width ratio b:a is 1:1.5, which is suitable for daily leisure and walking. One end of the rapid flow section 60 extends into the power cabin 4;One end of the slow flow section 61 extends into the air guide channel 2. The air guide piece 6 utilizes the width difference between the rapid flow section 60 and the slow flow section 61 to make the air show speed difference in different flow directions: in the inflation stage, the air in the power cabin 4 flows rapidly into the transducer cabin 3 through the rapid flow section 60, and then flows into the air guide channel 2 through the slow flow section 61;In the air return stage, the air in the air guide channel 2 flows slowly back to the transducer cabin 3 through the slow flow section 61, and then flows back to the power cabin 4 through the rapid flow section 60. The width difference structure design of the air guide piece 6 avoids the rapid back and forth of air between the power cabin 4 and the air guide channel 2, effectively prevents the attenuation of the buffering performance, and finally realizes the asymmetric flow between the two. The transition section 62 can guide the smooth flow of air from the rapid flow section 60 into the slow flow section 61, avoid air flow impact jam, and ensure smooth air flow.
[0033] In the technical scheme, the air guiding member 6 is made of a porous material in a strip shape, and the pores are uniform. In the embodiment, the air guiding member 6 is made of resin fiber. The air flow passes through the tiny gaps between the internal fibers of the resin fiber material to complete the air flow circulation. The air passes through the microscopic gaps between the resin fiber and the fiber. The microscopic gaps are interconnected to form air flow channels. The width of the rapid flow section is narrow, and the width of the slow flow section is wide, so as to form air channels with small cross-sectional area and air channels with large cross-sectional area, respectively.
[0034] The air chamber 1 is provided with a palm air energy rebound damping body 5. The inside space of the power chamber 4 is provided with a base sheet 7. One end of the rapid flow section 60 extends into the power chamber 4. The middle part of the base sheet 7 is provided with a through hole 70. The bottom edge of the base sheet 7 is surrounded and spaced apart by a plurality of support columns 71. The base sheet 7 and the support columns 71 are integrally made of TPU material. The overall height of the support columns 71 and the base sheet 7 is adapted to the internal height of the power chamber 4. The transverse section of the support column 71 is a circular rectangular shape, and the four sides are trapezoidal. The overall shape is large on the upper surface and small on the lower surface, that is, the upper part is thick and the lower part is thin. The upper thick structure can enhance the connection stability of the support column 71 and the base sheet 7. The lower thin structure can reduce the extrusion on the bottom of the power chamber 4. The trapezoidal side can disperse the pressure. A plurality of support columns 71 are uniformly and spaced apart along the bottom edge of the base sheet 7. The air gap 72 is formed between the adjacent support columns 71.
[0035] The top of the power cabin 4 is provided with an air inlet hole 40 at the position of the through hole 70 of the base sheet 7, which is used to supplement the external air for the power cabin 4, and ensures that there is enough air in the air pressure power shock absorbing and rebounding component during movement to maintain the shock absorption, and avoids the attenuation of the buffer due to air loss. The inner wall of the top of the power cabin is fixed with the fixed end 90 of the one-way valve sheet 9, the other end of the one-way valve sheet 9 is the free end 91, the fixed end of the one-way valve sheet is fixed with the inner wall of the top of the power cabin by hot melt welding or bonding, the free end is clamped between the top wall of the power cabin and the top of the base sheet, and the one-way valve sheet is located below the air inlet hole. The one-way valve sheet 9 does not completely cover the through hole and does not affect the airflow circulation of the through hole 70 of the base sheet 7; the one-way valve sheet 9 is configured to allow air to quickly enter the power cabin 4 from the outside through the air inlet hole 40, and prevent air from quickly discharging from the power cabin 4 through the air inlet hole 40. The one-way valve sheet 9 is made of an elastic material, such as a TPE film. When the power cabin 4 inhales, the one-way valve sheet 9 is pushed open by the airflow, and the air inlet channel is unobstructed. When the air is discharged, the one-way valve sheet 9 is pressed on the air inlet hole 40 by the air pressure, blocking the air outlet channel. The one-way valve sheet 9 opens or closes the air inlet hole 40 under the action of the air pressure difference, thereby ensuring that air can quickly enter the power cabin 4, and air flow is hindered when air flows out, achieving the effect of fast air intake and slow air outlet. Preferably, in order to further improve the buffer and reset effect, the bottom of the base sheet 7 is provided with a rear palm elastic body 8, which is located in the space surrounded by the plurality of support columns 71, and can disperse the pressure borne by the support columns 71, and assist the power cabin 4 to quickly reset after being stepped on, to ensure that the power cabin 4 can timely inflate the air cabin 1 when landing next time. The front palm gas energy rebound shock absorbing body 5 and the rear palm elastic body 8 are both open-cell polyurethane foam, and the density of the front palm gas energy rebound shock absorbing body 5 is greater than that of the rear palm elastic body 8. The high density of the front palm gas energy rebound shock absorbing body 5 realizes strong support for the front palm, and the low density of the rear palm elastic body 8 realizes soft shock absorption for the rear palm.
[0036] The application also provides a shoe pad, which comprises a shoe pad body 300, and the shoe pad body 300 is internally provided with the air pressure power shock absorbing and rebounding component as described above. Specifically, the shoe pad body 300 comprises a surface layer 302 and a bottom layer 301, the edges of the surface layer 302 and the bottom layer 301 are fixed together by means of adhesive or sewing, and the inside forms a space for accommodating the air pressure power shock absorbing and rebounding component, and the space is adapted to the shape of the air pressure power shock absorbing and rebounding component, and the space is provided with an expansion allowance of the air pressure power shock absorbing and rebounding component. The surface layer 302 is made of soft fabric with sweat absorption and air permeability, such as bamboo fiber / mode blended fabric, ultra-thin air permeable mesh cloth or imitation suede fabric. The bottom layer 301 is made of TPU film, high-density EVA sheet or non-woven fabric composite fabric. The surface layer 302 is provided with a through hole 303 at the position corresponding to the air inlet hole 40, so that the air inlet hole 40 is completely exposed.
[0037] The present application also provides a shoe sole, comprising a shoe sole body 100, wherein a sandwich space 101 for accommodating the air pressure power shock-absorbing and rebounding component is arranged inside the shoe sole body 100, the sandwich space 101 is matched with the shape of the air pressure power shock-absorbing and rebounding component, and one side or the top of the sandwich space 101 is provided with a shoe sole air-permeable hole 103 connected with the outside air, so that the sandwich space 101 is communicated with the outside air through the shoe sole air-permeable hole 103.

The surface of the shoe sole body 100 is covered with a shoe pad 200, the shoe pad 200 is provided with a shoe pad air-permeable hole 201 corresponding to the position of the air inlet hole 40 of the air pressure power shock-absorbing and rebounding component, so that the air inlet hole 40 is completely exposed. The shoe pad 200 and the shoe sole body 100 are fixed by means of adhesion or magic tape.
[0038] The present application also provides a shoe, comprising a shoe sole and a vamp arranged on the top of the shoe sole, wherein the shoe sole is the shoe sole containing the air pressure power shock-absorbing and rebounding component.
[0039] In a specific implementation, the forefoot air chamber 1 is provided with a forefoot air spring 5 to provide cushioning and elastic feedback when the foot lands on the forefoot and exerts force, helping to disperse pressure and reduce the impact force on the forefoot, while also providing some support. The base sheet 7 in the power chamber 4, in combination with the support column 71, forms a support body for the rear foot, providing stable support and dispersing pressure on the rear foot. The rear foot elastic body 8 absorbs the impact when the foot lands on the rear foot, providing a cushioning effect. The invention undergoes an inflation process and a deflation process when implemented. The inflation process is as follows: during intense exercise, air first enters the power chamber 4 through the air inlet hole 40. When the foot lands on the rear foot elastic body 8, the air in the power chamber 4 is compressed and quickly enters the energy conversion chamber 3 through the narrow cross-sectional area of the rapid flow section 60 of the air guide 6, then slowly enters the air guide channel 2 through the slow flow section 61 of the air guide 6, and finally enters the air chamber 1, inflating the air chamber 1 and providing cushioning for the forefoot. Because the airflow enters the wide slow flow section 61 and the energy conversion chamber 3 from the rapid flow section 60, the cross-sectional area of the gas flow suddenly increases, causing the airflow to diffuse and slow down, and the excess gas is temporarily stored in the energy conversion chamber 3. After temporary storage, the gas is slowly released into the air guide channel 2, achieving the softness of the forefoot inflation. The deflation process is as follows: when the foot lands on the air chamber 1, the air in the air chamber 1 enters the air guide channel 2, and the air in the air guide channel 2 slowly flows into the energy conversion chamber 3 through the wide cross-sectional area of the slow flow section 61, and then returns to the power chamber 4 through the rapid flow section 60. The energy conversion chamber 3 temporarily stores a small amount of gas that does not flow back to the power chamber 4 in time, and after temporary storage, it can maintain the basic air pressure in the energy conversion chamber 3, ensuring a smooth return of the air. Because the air flow through the slow flow section 61 of the air guide 6 is slow, and the one-way valve 9 hinders the outflow of air, the speed of the air returning to the power chamber 4 is significantly reduced, achieving the effect of fast inflow and slow outflow, ensuring that the invention can provide stable cushioning support during exercise. During the inflation and deflation stages, the energy conversion chamber 3 is the only way for air to flow between the power chamber 4 and the air guide channel 2, providing a transfer chamber for the gas, allowing the slow flow section 61 and the rapid flow section 60 of the air guide 6 to effectively connect the airflow, and temporarily storing gas to resolve the speed difference between the rapid flow section 60 and the slow flow section 61, avoiding sudden changes in air pressure, and ultimately ensuring the stability of the cushioning effect. EMBODIMENT
[0040] The difference between the present embodiment and embodiment one is that the front palm is quickly inflated and supported by adjusting the access position of the two passages of the air guide member. Specifically, one end of the rapid flow section 60 extends through and enters the inside of the air guide passage 2; one end of the slow flow section 61 extends through and enters the power cabin 4. The air guide member 6 uses the width difference between the rapid flow section 60 and the slow flow section 61 to make the air show a speed difference in different flow directions: in the inflation stage, the rear palm is stepped on, the power cabin 4 is pressurized, the air in the power cabin 4 slowly flows into the energy conversion cabin 3 through the slow flow section 61 for temporary storage, and then quickly enters the air guide passage 2 through the rapid flow section 60, and finally inflates the air cabin 1; in the air return stage, the air cabin is pressurized, the air in it quickly flows into the energy conversion cabin 3 through the rapid flow section 60, and then slowly flows back to the power cabin 4 through the slow flow section 61, while the external air quickly supplements the power cabin 4 through the air inlet hole at the top of the power cabin 4, ensuring that the power cabin 4 always maintains a stable air pressure. The width difference structure design of the air guide member 6 avoids the rapid back and forth of air between the power cabin 4 and the air guide passage 2, effectively prevents the attenuation of the buffering performance, and finally realizes the asymmetric flow between the two. The transition section 62 can guide the smooth flow of air from the slow flow section 61 into the rapid flow section 60, avoid air flow impact jamming, and ensure smooth air flow.
[0041] In a specific implementation, the forefoot air chamber 1 is provided with a forefoot air spring 5 to provide cushioning and elastic feedback when the foot lands on the forefoot and exerts force, helping to disperse pressure and reduce the impact on the forefoot, while also providing some support. The base sheet 7 in the power chamber 4 combines with the support column 71 to form a support body for the rear foot, providing stable support and dispersing the pressure on the rear foot, and the rear foot elastic body 8 absorbs the impact when the foot lands on the rear foot to provide cushioning effect. The invention will go through the inflation process and the deflation process when implemented. Among them, the inflation process is as follows: during intense exercise, air first enters the power chamber 4 through the air inlet hole 40. When the foot lands on the rear foot elastic body 8, the air in the power chamber 4 is squeezed, slowly enters the energy conversion chamber 3 through the large cross-sectional area of the slow flow section 61 of the air guide 6, then quickly enters the air guide channel 2 through the rapid flow section 60 of the air guide 6, and finally enters the air chamber 1, inflating the air chamber 1 and providing cushioning for the forefoot. Because the airflow enters the narrow rapid flow section 60 and the energy conversion chamber 3 from the slow flow section 61, the cross-sectional area of the gas flow suddenly becomes smaller, causing the gas flow velocity to naturally increase, and the excess gas is temporarily stored in the energy conversion chamber 3. After temporary storage, the gas is also quickly released to the air guide channel 2, achieving rapid inflation of the air chamber and rapid support for the forefoot. The deflation process is as follows: when the foot lands on the air chamber 1, the air in the air chamber 1 enters the air guide channel 2, the air in the air guide channel 2 quickly flows into the energy conversion chamber 3 through the narrow cross-sectional area of the rapid flow section 60, and then returns to the power chamber 4 through the slow flow section 61. The energy conversion chamber 3 temporarily stores the gas that does not flow back to the power chamber 4 in time, and after temporary storage, it can maintain the basic air pressure in the energy conversion chamber 3 to ensure smooth air return. Because the air flow through the slow flow section 61 of the air guide 6 is slow, and the one-way valve 9 hinders the outflow of air, the air returns to the power chamber 4 at a slower speed, and the external air enters the air inlet hole to supplement the air in the power chamber, ensuring that the invention can continuously provide stable cushioning support during exercise. In the inflation and deflation stages, the energy conversion chamber 3 is the only way for air flow in the inflation and deflation stages, acting as a transfer chamber to connect the slow flow section 61 and the rapid flow section 60 of the air guide 6, and also storing gas to resolve the speed difference between the slow flow section 61 and the rapid flow section 60, avoiding sudden pressure rise and fall, and ultimately achieving stability in the cushioning effect.
