Description

TECHNICAL FIELD

[0001] The present application relates to the field of shoe soles, in particular to a multifunctional sports shoe sole. BACKGROUND

[0002] Shoes are a necessity in daily life, with multiple functions such as warmth protection and appearance beautification. However, the existing conventional shoe soles generally have the following defects: first, the cushioning and shock absorption performance is insufficient, and the ground impact force cannot be effectively attenuated during walking or movement, which easily causes foot fatigue after long-term use, and even adversely affects joint health; second, the air permeability is poor, and the air in the shoe is difficult to circulate effectively, which easily causes the feet to be damp and hot after long-term wearing, and further breeds bacteria and produces odor, which seriously reduces the wearing comfort; third, most traditional shoe soles do not have an effective waterproof structure, and water easily penetrates into the shoe in the presence of water or in a humid environment, which greatly limits the application scenarios of the shoe and affects the wearing experience. Based on this, developing an improved shoe sole with shock absorption, air permeability and waterproof comprehensive performance has important practical significance for improving the overall quality of shoe products. SUMMARY

[0003] The present application provides a multifunctional sports shoe sole to solve the problems of insufficient shock absorption, poor air permeability and rapid water penetration of existing shoe soles.

[0004] The present application adopts the following technical solutions:

[0005] A multifunctional sports shoe sole, comprising a midsole and an outsole, the midsole is composed of a midsole lower layer and a midsole upper layer, the bottom surface of the midsole lower layer is provided with a plurality of first grooves, the first grooves are in a hemispherical structure, an exhaust groove is provided on the side wall of the first groove and communicates with the outside of the midsole lower layer, the exhaust groove is spirally arranged on the outside of the first groove, the groove width of the exhaust groove gradually decreases from the inside to the outside, the outsole is provided with a second groove corresponding to the first groove, and the groove bottom of the second groove is bulged downward from the bottom surface of the outsole; a support stabilizing sheet is arranged between the midsole lower layer and the midsole upper layer, the midsole upper layer, the support stabilizing sheet and the midsole lower layer are respectively provided with through holes aligned with each other, and the through hole of the midsole lower layer is located at the groove bottom of the first groove.

[0006] Further, the first groove and the second groove cooperate to form a containing cavity, a ball made of elastic silica gel or EVA is arranged in the containing cavity, and the ratio of the depth of the first groove to the diameter of the ball is 1:1.2.

[0007] Further, the material of the support stabilizing sheet is TPU or carbon fiber.

[0008] Further, the exhaust groove is provided with a water blocking device, the water blocking device is arranged near the slot of the outer end of the exhaust groove, and the height of the water blocking device is less than the depth of the exhaust groove.

[0009] Further, the width of the exhaust groove is 2-6mm.

[0010] Further, the bottom surface of the lower midsole is provided with four first grooves, which are distributed in the instep part of the lower midsole.

[0011] Further, the upper surface of the lower midsole is provided with a mounting groove, and the support stabilizing piece is placed in the mounting groove. The left and right sides of the support stabilizing piece are respectively provided with limiting blocks, and the edge of the mounting groove is provided with a limiting groove for inserting the limiting blocks.

[0012] Further, the middle part of the outsole is bonded with a glass fiber anti-skid piece, and the bottom surface of the glass fiber anti-skid piece is in a frosted structure.

[0013] Further, the bottom surface of the outsole is provided with anti-skid patterns.

[0014] From the above description of the structure of the present application, compared with the prior art, the present application has the following advantages:

[0015] 1. The instep part (core stress area) of the present application is provided with four first hemispherical grooves, which form a containing cavity with the second groove of the outsole. The cavity is filled with elastic silica gel or EVA balls. When the balls are stressed, they deform fully and rebound quickly, can efficiently absorb the impact force of the ground, greatly attenuate the reaction force of the foot during walking or movement, solve the foot fatigue problem caused by the insufficient shock absorption of the traditional sole, and reduce the damage to the joints such as ankle and knee during long-term use.

[0016] The support stabilizing piece (TPU or carbon fiber material) of the midsole interlayer has high strength and certain toughness, which can avoid excessive deformation of the sole affecting the walking stability, and also does not hinder the buffering and rebound of the balls and the midsole, forming a "buffering-supporting" two-way protection, so that the sole has excellent shock absorption performance while maintaining the foot support during walking, avoiding the instability of gait caused by excessive softness.

[0017] 2. The aligned through holes (through holes located in the groove bottom) of the upper midsole, the support stabilizing piece, and the lower midsole form a channel for the air in the shoe to communicate with the outside. The spiral exhaust groove of the side wall of the first groove gradually decreases in width from the inside to the outside. When walking, the elastic balls compress the air in the groove, and the air pressure difference generated by the "gradual change of groove width" accelerates the airflow to be discharged. At the same time, the moisture in the shoe can be introduced into the groove through the through hole, and then discharged with the airflow through the exhaust groove, realizing efficient circulation of the air in the shoe and completely solving the problem of damp and hot caused by poor ventilation of the traditional sole.

[0018] The arc-shaped side wall of the semispherical groove cooperates with the spiral exhaust groove to make the air flow discharge path smoother, avoid air flow retention, and at the same time, the through hole is precisely connected with the groove bottom, so that the moisture can be directed into the buffer cavity, and then discharged through the exhaust groove, thereby greatly reducing the bacterial breeding and odor generation in the shoe, and improving the comfort of long-time wearing.

[0019] 3. The water blocking device is arranged at the outer end slot of the exhaust groove of the present application, which can form a physical barrier to block external moisture, sand and stones (rainwater, ground water, etc.) from flowing into the shoe through the exhaust groove, overcome the defects of traditional shoe soles without effective waterproof structure and easy water penetration, and enable the shoe to be normally used in a humid environment or rainy day, thereby widening the application scenarios.

[0020] The installation and positioning design of the upper and lower layer composite structure of the insole and the support stabilizing sheet reduces the gap of the insole, further reduces the risk of moisture penetration, and the position of the water blocking device can precisely intercept moisture, avoiding the penetration of moisture along the spiral path of the exhaust groove.

[0021] 4. The glass fiber anti-skid sheet bonded in the middle part of the outsole of the present application cooperates with the anti-skid pattern of the bottom surface, the frosted glass fiber sheet improves the basic anti-skid effect by increasing the friction force of the contact surface, and the anti-skid pattern further optimizes the ground gripping performance, especially on wet and slippery ground (ceramic tiles, rainy road surface), which can effectively enhance the adhesion between the outsole and the ground, and reduce the risk of slipping.

[0022] The glass fiber material has high strength and good wear resistance, the frosted structure is not easy to fail due to long-term wear, and the anti-skid performance is long-term stable in cooperation with the overall material properties of the outsole, solving the problem of easy wear of the anti-skid pattern of the traditional outsole and insufficient ground adhesion on wet and slippery ground.

[0023] 5. The mounting groove on the upper surface of the lower layer of the insole of the present application precisely cooperates with the limiting block of the support stabilizing sheet and the limiting groove of the edge of the mounting groove, which can firmly fix the position of the support stabilizing sheet, avoid displacement and falling of the stabilizing sheet due to stress during use, ensure the continuous stability of the support effect, prevent the separation of the upper and lower layers of the insole, and improve the overall structural firmness of the insole.

[0039] The width of the air exhaust groove 122 is 2-6 mm, preferably 2 mm at the outer end and 4 mm at the inner end, so that water outside the sole is less likely to enter the sole.

[0040] The bottom surface of the lower layer 12 of the midsole is provided with four first grooves 121, which are distributed in the sole of the foot. The sole of the foot (the core stress area) is provided with four semispherical first grooves 121, which form a containing cavity with the second groove 20 of the outsole 2, and an elastic silica gel or EVA ball 22 is arranged in the containing cavity.

[0041] Referring to Figure 4 , Figure 5 The upper surface of the lower layer 12 of the midsole is provided with a mounting groove 120, and the support stabilizing piece 13 is placed in the mounting groove 120. The left and right sides of the support stabilizing piece 13 are respectively provided with limiting blocks 131, and the edge of the mounting groove 120 is provided with limiting grooves 130 for inserting the limiting blocks.

[0043] The bottom surface of the above-mentioned outsole 2 is provided with anti-skid patterns. Embodiment

[0044] Reference Figures 1-3 A multifunctional sports shoe sole includes a midsole 1 and an outsole 2. The above-mentioned midsole 1 is composed of a midsole lower layer 12 and a midsole upper layer 11. Figures 6-9 The bottom surface of the above-mentioned midsole lower layer 12 is provided with a plurality of first grooves 121 in a semispherical structure. An exhaust groove 122 is provided on the sidewall of the first groove 121 and communicates with the outside of the midsole lower layer 12. The exhaust groove 122 is spirally arranged on the outside of the first groove 121, and the groove width of the exhaust groove 122 gradually decreases from inside to outside. The above-mentioned outsole 2 is provided with a second groove 20 corresponding to the first groove 121, and the groove bottom of the second groove 20 is bulged downward from the bottom surface of the outsole 2. The above-mentioned midsole lower layer 12 and the above-mentioned midsole upper layer 11 are clamped with a support stabilizing sheet 13 therebetween. The midsole upper layer 11, the support stabilizing sheet 13 and the midsole lower layer 12 are respectively provided with through holes 100 aligned with each other, and the through hole 100 of the midsole lower layer 12 is located at the groove bottom of the above-mentioned first groove 121.

[0045] Reference Figure 7 The above-mentioned first groove 121 and the above-mentioned second groove 20 cooperate to form a containing cavity, and a ball 22 made of elastic silica gel or EVA is assembled in the containing cavity. The ratio of the depth of the first groove 121 to the diameter of the ball 22 is 1:1.2. When the sole is stepped on, the groove bottom of the second groove 20 is retracted into the sole, and the elastic ball 22 is lifted up and compressed, so that the air pressure difference accelerates the airflow to be discharged, and at the same time, the moisture in the shoe can be introduced into the groove through the through hole 100 and then discharged through the exhaust groove 122, and the elastic ball 22 blocks the through hole 100 to prevent the road water from flowing into the shoe. Alternatively, when the sole is lifted, the elastic force of the restored deformation of the ball 22 causes the groove bottom of the second groove 20 to bulge downward, and the ball 22 is separated from the inner wall of the first groove 121, so that the outside air can enter the sole, realizing air convection and improving the air permeability in the shoe.

[0046] The material of the support stabilizing piece 13 is TPU or carbon fiber, preferably TPU, which has high strength and certain toughness, avoids excessive deformation of the shoe sole affecting walking stability, does not hinder the cushioning and rebound of the ball 22 and the midsole 1, forms a "cushioning-supporting" two-way protection, and makes the shoe sole have excellent shock absorption performance while maintaining the foot support during walking, avoiding gait instability caused by excessive softness.

[0048] The width of the exhaust groove 122 is 2-6mm, preferably 2mm at the outer end and 4mm at the inner end, so that water outside the shoe sole is less likely to enter the shoe sole.

[0049] The bottom surface of the midsole lower layer 12 is provided with four first grooves 121, which are distributed in the sole of the midsole lower layer 12. The sole (core stress area) is provided with four semispherical first grooves 121, which form a containing cavity with the second groove 20 of the outsole 2, and an elastic silica gel or EVA ball 22 is arranged therein. The ball 22 deforms fully and rebounds quickly when stressed, can efficiently absorb ground impact force, greatly attenuate the reaction force on the foot during walking or exercise, solve the problem of foot fatigue caused by insufficient shock absorption of traditional shoe soles, and reduce damage to joints such as ankles and knees during long-term use.

[0050] Referring to Figure 4 , Figure 5 The upper surface of the midsole lower layer 12 is provided with a mounting groove 120, and the support stabilizing piece 13 is placed in the mounting groove 120.

[0051] Referring to Figure 1 The middle part of the outsole 2 is bonded with a glass fiber anti-skid piece 21, the bottom surface of which is in a frosted structure. The glass fiber has high strength and good wear resistance, the frosted structure is not easy to fail due to long-term wear, and the combination of the overall material properties of the outsole 2 makes the anti-skid performance stable for a long time, solving the problem of insufficient grip on wet ground caused by easy wear of traditional shoe soles.
