They are relational words determined only for the convenience of describing the structural relationships of the various parts or elements of the present disclosure, and do not specifically refer to any part or element in the present disclosure and should not be understood as limitations on the present disclosure.

[0028] The present invention discloses a sole with a hollow energy storage structure, referring to Figure 1 , Figure 7The sole comprises an upper sole 1, a midsole 2 and an outsole 3 which are arranged in sequence from top to bottom. The upper sole 1 and the midsole 2 are detachably connected, and the height of the entire sole can be adjusted by disassembling and assembling the upper sole 1. The outsole 3 adopts a hollow design. Specifically, a plurality of through holes 4 which are interconnected are symmetrically arranged on both sides of the bottom of the outsole 3. The elastic energy storage of the sole is achieved under the adjustment of each through hole 4. Specifically, during exercise, the through hole 4 is squeezed, and during the squeezing process, the sole stores energy. During exercise, the energy-stored sole provides a reverse force for the athlete, achieving the effect of energy storage and high elasticity. At the same time, the plurality of through holes 4 enable wind to pass through the sole through the plurality of through holes 4 during exercise to reduce the resistance of the sole during exercise.

[0029] A first elastic energy storage device is provided between the midsole 2 and the outsole 3 corresponding to the heel, and the first elastic energy storage device includes an airbag ball 5 fixedly penetrating the heel of the midsole 2, and one-way air valves are provided on both sides of the airbag ball 5. The ventilation directions of the two one-way air valves are opposite, one of which is used for exhausting the airbag ball 5, and the other one-way air valve is used for inletting air into the airbag ball 5. An air outlet pipe 6 and an air inlet pipe 7 are provided on both sides of the airbag ball 5. The diameters of the two ends of the air outlet pipe and the air inlet pipe 7 close to the airbag ball 5 are larger than the diameters of the other ends, so that the airbag ball 5 can be exhausted when the air is exhausted. The gas is discharged quickly and the gas is gradually compressed. When inhaling, the gas can be inhaled quickly, so that the airbag ball 5 can be filled with gas in an instant. The corresponding positions on the surface of the outsole 3 are provided with connecting grooves 8 that are detachably connected to the air inlet pipe 7 and the air outlet pipe 6, and the surface is also provided with a first groove 9 adapted to the airbag ball 5. The ends of the air inlet pipe 7 and the air outlet pipe 6 away from the airbag ball 5 are provided with connectors for connecting with the connecting grooves 8. A first mounting groove 10 is provided in the outsole 3, and first air passages 11 connected thereto are provided on both sides of the first mounting groove 10. The two first air passages 11 The connection between the connecting groove 8 and the connecting head is connected with the air inlet pipe 7 and the air outlet pipe 6. The first installation groove 10 is connected with the through hole 4, so that the air outside the sole can enter the first installation groove 10, and a fan 12 is arranged in the first installation groove 10. During exercise, the heel of the foot generally touches the ground first, so that the heel squeezes the airbag ball 5, so that the air in the airbag ball 5 is instantly discharged into the first installation groove 10 through the air outlet pipe 6 and the first air channel 11. Due to the fast air discharge speed and the gradual increase in the diameter of the air outlet pipe 6 during the air transportation process, the air The change makes the air flow faster when entering the first mounting groove 10. A faster air flow rate can drive the fan 12 to rotate. Due to the rotation of the fan 12 and the negative pressure formed by the air in the airbag ball 5 being emptied, the air outside the sole can pass through the first air duct 11 and the air inlet pipe 7 to instantly fill the airbag ball 5 under the action of the fan 12 and the negative pressure. During the instantaneous filling process, the airbag ball 5 instantly generates a high elasticity on the heel, and a circulating high-energy storage system is formed at the heel of the sole through the airbag ball 5, the air outlet pipe 6, the mounting groove and the two first air ducts 11.

[0030] Reference Figure 2 The specific connector includes a threaded sleeve 13, a connecting plate 14 and a sealing gasket arranged in the threaded sleeve 13, the sealing gasket 15 is located above the connecting plate 14, and the air inlet pipe 7 and the air outlet pipe 6 both pass through the connecting sleeve and the sealing gasket 15 and are connected to the connecting plate 14. The groove wall of the connecting groove 8 is provided with a thread that matches the threaded sleeve 13. The outer surface of the threaded sleeve 13 is also provided with a thread, and the threaded sleeve 13 can be screwed into the connecting groove 8 to realize the connection between the air inlet pipe 7 or the air outlet pipe 6 and the first air passage 1. 1, when the threaded sleeve 13 is inserted into the connecting groove 8, when air flows in the air inlet pipe 7 or the air outlet pipe 6, the air will squeeze the connecting plate 14 and the sealing gasket 15. Under the action of the air pressure, the connecting plate 14 continues to squeeze the sealing gasket 15, so as to achieve the airtightness of the connection between the connecting groove 8 and the threaded sleeve 13, and prevent air leakage between the air inlet pipe 7 or the air outlet pipe 6 and the first air passage 11. Two second mounting grooves 16 are provided on the bottom surface of the midsole 2 at the positions on both sides of the airbag ball 5, referring to Figure 5 A winding drum 17 is rotatably installed in the two second installation grooves 16. If the air inlet pipe 7 or the air outlet pipe 6 is too long, in order to prevent the air inlet pipe 7 or the air outlet pipe 6 from bending, resulting in poor air circulation, the air inlet pipe 7 or the air outlet pipe 6 can be wound on the winding drum 17, which effectively prevents the air inlet pipe 7 and the air outlet pipe 6 from bending.

[0031] Reference Figure 8 The airbag ball 5 includes an outer sphere 51 and an inner sphere 52 sleeved in the outer sphere 51. The outer sphere 51 is provided with an air outlet 18 and an air inlet 19 on both sides. The inner sphere 52 is close to the air inlet 19 and fits with the inner wall of the outer sphere 51. The inner sphere 52 is connected to the air inlet 19 on one side and is separated from the air outlet 18 on the other side. The side wall of the inner sphere 52 is a hollow cavity structure, which is connected to the air inlet 19. The inner sphere 52 is concave at one end close to the air outlet 18 to form a cavity toward the air inlet 19. 9 ventilation annular air outlet 18, when air enters the inner sphere 52 from the air inlet 19, it also enters the hollow cavity structure and enters the inner sphere 52 again from the annular air outlet 18. At this time, air is introduced into both sides of the inner sphere 52, and an air inlet structure opposite to each other is generated in the inner sphere 52, so that the air introduced from both sides collides in the inner sphere 52, so that a collision impact force is instantly generated in the inner sphere 52, further increasing the size of the high elastic force generated by the stored force of the airbag ball 5.

[0032] Reference Figure 1A second elastic energy storage device is provided at the sole between the midsole 2 and the outsole 3. The second elastic energy storage device includes a third mounting groove 20 provided in the outsole 3, and an elastic mechanism slidably provided in the third mounting groove 20. The bottom of the elastic mechanism is located in the third mounting groove 20, and the top passes through the third mounting groove 20 and extends upward to be connected with the bottom surface of the midsole 2. A buckle device is provided at the bottom of the third mounting groove 20. The buckle device can clamp and fix the elastic mechanism to fix the elastic mechanism in the third mounting groove 20. The bottom surface of the outsole 3 is also provided with an adjustment mechanism.

Figure 3 The specific elastic mechanism includes a chuck 21 arranged in the third mounting groove 20, a connecting rod 22 that penetrates the third mounting groove 20, and a first return spring 23 that is sleeved on the connecting rod 22. The bottom end of the connecting rod 22 is connected to the chuck 21, and the top end is connected to the bottom surface of the midsole 2. The first return spring 23 is located between the midsole 2 and the outsole 3. Specifically, the buckle device includes two symmetrically arranged slots 24 on the side wall of the third mounting groove 20, two blocks 25 arranged in the two slots 24, and two second return springs 26. The second return spring 26 is located between the slot 24 and the block 25, and one end is connected to the card block 25. The first end of the first return spring 23 is connected to the inner wall of the groove 24, and the other end is connected to the block 25. The end of the block 25 away from the second return spring 26 is a rounded structure and can extend into the third installation groove 20. When the chuck 21 moves downward, the block 25 can be squeezed to overcome the elastic force of the second return spring 26 and move to the inside of the slot 24. When the chuck 21 is separated from the block 25, the block 25 moves into the third installation groove 20 under the action of the second return spring 26 and clamps the chuck 21 to the bottom of the third installation groove 20. At this time, the first return spring 23 is completely compressed, and the midsole 2 and the outsole 3 fit together. Figure 4The adjusting mechanism includes a fourth mounting groove 27 which is arranged at the bottom of the large bottom 3 and has an opening at the bottom, a protrusion 28 which is slidably mounted in the fourth mounting groove 27, and a toothed roller 29 which is rotatably arranged in the fourth mounting groove 27. The surface of the toothed roller 29 is a gear structure. A rack 30 is arranged on the top of the protrusion 28. The rack 30 is meshed and connected with the toothed roller 29. When the protrusion 28 drives the rack 30 to move upward, the toothed roller 29 can be driven to rotate. The adjusting mechanism also includes a pull rope 31 which is arranged in the large bottom 3. One end of the pull rope 31 passes through the second return spring 26 and is connected to the block 25, and the other end is wound on the toothed roller 29. It also includes a plurality of guide rollers 32 which are arranged in the large bottom 3 and contact the pull rope 31. The pull rope 31 and the guide roller 32 in the large bottom 3 have Corresponding to the mounting groove (not shown in the figure), during the movement, when the heel of the sole touches the ground and squeezes the protrusion 28, the protrusion 28 drives the rack 30 to move upward, and then drives the toothed roller 29 to rotate to reel in the drawstring 31, so that the drawstring 31 pulls the block 25 to move inside the slot 24, so that under the action of the first return spring, the midsole 2 and the outsole 3 are separated, and the elastic force of the first return spring 23 is instantly converted into the kinetic energy of the sole, so that a high-elastic energy storage structure is formed at the sole of the sole. When the sole leaves the ground, the block 25 moves into the third mounting groove 20 under the action of the second return spring 26, which drives the drawstring 31 to move in the opposite direction. At this time, the toothed roller 29 rotates in the opposite direction and drives the protrusion 28 to move downward through the rack 30, so that the protrusion 28 is reset.

[0033] Reference Figure 1 A plurality of second elastic energy storage devices are arranged side by side between the outsole 3 and the midsole 2, and the protrusions 28 are also arranged side by side on the bottom surface of the sole. Since the sole touches the ground from the heel during exercise, each protrusion 28 is continuously squeezed, so that the sole generates a greater elastic force under the action of the plurality of first return springs 23. The protrusion 28 is divided into two detachably connected upper protrusions 281 and lower protrusions 282 with the bottom surface of the outsole 3 as a dividing line. Specifically, the upper protrusion 281 and the lower protrusion 282 are detachably connected by threads. By disassembling and assembling the lower protrusion 282, whether to use the second elastic energy storage device can be determined according to actual needs, which is convenient for the wearer to freely choose.
