It does not specifically refer to any component or element in the disclosure, and cannot be understood as Limitations on this Disclosure.

The invention discloses an energy storage sports shoe sole with a rebound function. Referring to Fig. 1 and Fig. 7, the sole includes an upper bottom 1, a middle bottom 2 and a large bottom 3 arranged in sequence from top to bottom, and the upper bottom 1 and the middle bottom 2 are detachably connected, and the adjustment of the height of the entire sole can be realized through the disassembly and assembly of the upper bottom 1. The outsole 3 adopts a hollow design. Specifically, a plurality of interconnected channels are arranged symmetrically on both sides of the bottom of the outsole 3. Holes 4 realize the elastic energy storage of the sole under the adjustment of each through hole 4. Specifically, during the exercise process, the through hole 4 is squeezed, and during the extrusion process, the sole carries out force storage. The high-energy sole provides the athlete with a reverse force to achieve the effect of energy storage and high elasticity. At the same time, multiple through holes 4 allow the wind to pass through the sole through multiple through holes 4 during exercise to reduce the impact of the sole during exercise. resistance.

Between the midsole 2 and the outsole 3, a first elastic energy storage device is arranged corresponding to the heel, and the first elastic energy storage device includes an airbag ball 5 fixedly penetrating through the heel of the midsole 2, on both sides of the airbag ball 5 Both are provided with one-way air valves, and the ventilation directions of the two one-way air valves are opposite. One of the one-way air valves is used for the exhaust of the air bag ball 5, and the other one-way air valve is used for the intake of the air bag ball 5. The two sides of airbag ball 5 are provided with air outlet pipe 6 and air intake pipe 7, and the diameters of the two ends of air outlet pipe and air inlet pipe 7 close to air bag ball 5 are all greater than the pipe diameter of the other end, so that air bag ball 5 can quickly air out when air outlet And the gas is gradually compressed, and the air can be inhaled quickly during the air intake, so that the airbag ball 5 can be filled with air in an instant, and the corresponding positions on the surface of the outsole 3 are provided with connecting grooves that are detachably connected with the air intake pipe 7 and the air outlet pipe 6 8, and the surface is also provided with the first groove 9 that is compatible with the airbag ball 5, and the end of the air inlet pipe 7 and the air outlet pipe 6 away from the airbag ball 5 is provided with a connecting head for connecting with the connecting groove 8. The bottom 3 is provided with a first installation groove 10, and a first air passage 11 communicating with it is arranged on both sides of the first installation groove 10. The two first air passages 11 are connected and connected between the connecting groove 8 and the connector The air intake pipe 7 and the air outlet pipe 6 are connected, and 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 the exercise, the heel of the foot generally touches the ground first, so that the airbag ball 5 is squeezed at the heel, 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 passage 11. Because the speed of air discharge is faster, and the air flow rate is faster when the air enters the first installation groove 10 due to the diameter of the air outlet pipe 6 gradually decreasing during the conveying process, the fan 12 can be driven more if the air flow rate is fast. Rotate, due to the negative pressure formed by the rotation of the fan 12 and the air in the air bag ball 5 being evacuated, the air outside the sole can pass through the first air channel 11 and the air intake pipe 7 instantaneously under the action of the fan 12 and the negative pressure. The ball 5 is full, and in the process of instantaneous filling, the airbag ball 5 instantly produces high elasticity on the heel, and through the airbag ball 5, the air outlet pipe 6, the installation groove and the two first air passages 11, the heel of the sole forms a cycle of high energy storage system.

Referring to Fig. 2, the specific connector includes a threaded sleeve 13, a connecting plate 14 and a sealing gasket arranged in the threaded sleeve 13, and the sealing gasket 15 is located above the connecting plate 14, and the air inlet pipe 7 and the air outlet pipe 6 all pass through the connecting sleeve and the sealing gasket 15 and connected with the connection plate 14, the groove wall of the connection groove 8 is provided with threads that are compatible with the threaded sleeve 13, and the outer surface of the threaded sleeve 13 is also provided with threads, so that the threaded sleeve 13 can be screwed into the connection groove 8 Realize the connection between the inlet pipe 7 or the outlet pipe 6 and the first air passage 11. When the threaded sleeve 13 is inserted into the connection groove 8, when there is air circulation in the inlet pipe 7 or the outlet pipe 6, the air will squeeze the connection plate 14 and The sealing gasket 15, under the action of air pressure, makes the connecting plate 14 continuously squeeze the sealing gasket 15, realizes the airtightness of the connection between the connecting groove 8 and the threaded sleeve 13, and prevents the air inlet pipe 7 or the air outlet pipe 6 from being connected to the first ventilation pipe. There is an air leakage between the channels 11, and two second installation grooves 16 are arranged at the bottom surface of the midsole 2 at both sides of the airbag ball 5. Referring to FIG. The trachea 7 or the air outlet pipe 6 are too long, in order to prevent bending between the air inlet pipe 7 or the air outlet pipe 6, resulting in unsmooth air circulation, the air inlet pipe 7 or the air outlet pipe 6 can be wound on the winding drum 17, effectively Prevent the air intake pipe 7 and the air outlet pipe 6 from being bent.

Referring to Fig. 8, the airbag ball 5 includes an outer sphere 51, an inner sphere 52 sleeved in the outer sphere 51, an air outlet 18 and an air inlet 19 are arranged on both sides of the outer sphere 51, and the inner sphere 52 is near the side of the air inlet 19 Fitted with the inner wall of the outer sphere 51 and the inside of the inner sphere 52 is connected with the air inlet 19, and the other side is separated from the air outlet 18. The side wall of the inner sphere 52 is a hollow cavity structure, and the hollow cavity structure is consistent with the The air inlet 19 is connected, and one end close to the air outlet 18 is recessed to form an annular air outlet 18 ventilated to the air inlet 19. When the air enters the inner sphere 52 from the air inlet 19, it enters the hollow cavity structure at the same time. , and pass into the inner sphere 52 again from the annular air outlet 18, at this moment, both sides in the inner sphere 52 all have air to pass into, produce the air intake structure that both sides are opposite in the inner sphere 52, make both sides pass into The air in the inner spheroid 52 collides, so that a collision impact force is generated in the inner spheroid 52, and further improves the size of the high elastic force generated by the airbag ball 5 when the force is stored.
