Description

Technical Field

[0001] This utility model relates to the field of footwear technology, and more specifically to a heat-dissipating and breathable sports shoe sole and sports shoes. Background Technology

[0002] Athletic shoes are a type of functional footwear designed specifically for sports, fitness activities, or everyday exercise needs. They are characterized by providing support, cushioning, slip resistance, and protection during exercise, while also taking into account a certain degree of heat dissipation, comfort, and flexibility. However, existing athletic shoes have relatively weak heat dissipation, usually relying on the upper side of the sole for heat dissipation, which leads to sweaty feet, bacterial growth, and affects the wearer's health.

[0003] In view of this, this application has conducted in-depth research on this basis, resulting in this case. Utility Model Content

[0004] The purpose of this invention is to provide a heat-dissipating and breathable sports shoe sole and sports shoes.

[0005] To achieve the above objectives, the solution of this utility model is: A breathable and heat-dissipating athletic shoe sole includes a midsole and an insole connected sequentially from bottom to top, and also includes elastic support members. The midsole has a groove filled with an air bladder. A one-way air inlet valve is provided on the sidewall of the midsole. An airflow channel is provided between the one-way air inlet valve and the air bladder, and the airflow channel connects the air inlet end of the air bladder and the one-way air inlet valve. The insole has ventilation holes that are connected to the air outlet end of the air bladder. Several elastic support members are provided, one end of which is connected to the midsole and the other end of which is connected to the insole. The elastic support members are placed in the groove and can compress the air bladder.

[0006] This invention employs a breathable structure formed by an elastic support component, ventilation holes, and airflow channels. When the foot presses down, the insole compresses the air bladder under pressure, causing the gas in the air bladder to flow out from the outlet end and be ejected through the ventilation holes into the shoe cavity above the insole; that is, the gas in the air bladder is compressed into the insole. When the downward pressure on the insole is released, i.e., when the foot is off the ground, external air enters the airflow channel through the one-way air inlet valve and then enters the air bladder, filling it with gas. This gas is then delivered back into the shoe cavity upon the next contact with the ground. The elastic support component is located within a groove. Due to its high elasticity, the elastic support component accelerates the compression deformation of the sole and quickly recovers, thus ensuring the stability and durability of the sole. When the elastic support component undergoes elastic deformation, it compresses the air bladder, thereby improving the circulation efficiency of the gas within the air bladder.

[0007] The height of the air bladder is greater than the depth of the groove. This design allows the air bladder to deform significantly when the insole is compressed, resulting in most of the gas in the air bladder being ejected into the shoe cavity above the insole.

[0008] The air bladder forms a recess, and the elastic support is embedded in the recess of the air bladder. This arrangement allows the elastic support to deform more elastically, compressing the air bladder and causing most of the gas in the air bladder to be ejected into the shoe cavity above the insole.

[0009] The groove is provided at the forefoot position of the midsole; several elastic support members are provided at the forefoot position of the midsole. The groove and elastic support members are located at the forefoot position of the midsole so that the elastic deformation of the groove and elastic support members is large, thereby compressing the air bladder to a large deformation, so that most of the gas in the air bladder is injected into the shoe cavity above the insole.

[0010] All of the aforementioned elastic support components are made of rubber material, and each elastic support component has a Shore hardness of 30-40A. The elastic support components utilize a hard-on-soft rubber material with a Shore hardness of 30-40A, exhibiting good elasticity and resilience.

[0011] All of the aforementioned elastic support components are made of supercritical foam material. The elastic support components use supercritical foam material, which has low density and good resilience.

[0012] Each of the aforementioned elastic support components is frustum-shaped, with its radius gradually increasing from the end connected to the insole to the end connected to the midsole. Designing the elastic support components as frustum-shaped (thinner at the top, thicker at the bottom) better distributes pressure and improves support stability.

[0013] Each of the aforementioned vents has a trapezoidal structure, and the diameter of each vent gradually decreases from the side furthest from the midsole to the side closest to the midsole. The trapezoidal structure of the vents helps guide airflow and improves breathability.

[0014] Each of the ventilation holes has a dustproof mesh fabric installed on its inner wall. The dustproof mesh fabric can prevent dust and impurities from entering the midsole, keeping the midsole clean.

[0015] A heat-dissipating and breathable sports shoe includes a sports shoe sole and a breathable shoe upper disposed on the sports shoe sole.

[0016] With the above structure, the beneficial effects of this utility model are as follows: When the foot presses down, the insole compresses the airbag under pressure, causing the gas in the airbag to flow out from the outlet end and be sprayed into the shoe cavity above the insole through the ventilation holes of the insole; when the foot is airborne, external air enters the airflow channel through the one-way air inlet valve and enters the airbag through the airflow channel to fill the airbag with gas, which is then delivered to the shoe cavity again when the foot touches the ground next; due to the setting of the elastic support component, the high elasticity of the component accelerates the compression deformation of the sole and quickly recovers, thereby ensuring the support stability and durability of the sole; when the elastic support component undergoes elastic deformation, it squeezes the airbag, thereby improving the circulation efficiency of the gas in the airbag, thus achieving the effects of breathability and heat dissipation.

[0019] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0020] like Figures 1 to 5As shown in the figure, this utility model discloses a breathable and heat-dissipating sports shoe sole. The sports shoe sole 100 is divided into a forefoot position, an arch position, and a heel position from front to back. The sports shoe sole 100 includes an outsole (not shown in the figure), a midsole 1, and an insole 2 connected sequentially from bottom to top. The outsole and midsole 1 are connected using a conventional sports shoe sole connection method, such as adhesive bonding. The sports shoe sole 100 also includes an elastic support member 3. In this embodiment, the midsole 1 is made of common elastic EVA material, and the midsole 1 is mainly used for shock absorption and support; the insole 2 is made of existing breathable foam material.

[0021] This utility model defines the side of the sports shoe sole 100 that is closer to the ground as the bottom and the side that is further away from the ground and closer to the foot as the top.

[0022] The midsole 1 has a groove 11, which is filled with an airbag 4. The sidewall 12 of the midsole 1 has a one-way air intake valve 41. An airflow channel 42 is provided between the one-way air intake valve 41 and the airbag 4. The airflow channel 42 connects the air intake end of the airbag 4 and the one-way air intake valve 41, and the one-way air intake valve 41 is connected to the outside air. In this embodiment, the airbag 4 is a conventional airbag with elastic reset function, which is used to deflate when the airbag 4 is squeezed and automatically inflate in the natural state.

[0023] The insole 2 is provided with a ventilation hole 21. The ventilation hole 21 is closed in its natural state. Under the action of external force, the ventilation hole 21 is elastic and opens. The ventilation hole 21 is connected to the air outlet of the air bag 4.

[0024] Several elastic support members 3 are provided. One end of each elastic support member 3 is connected to the midsole 1, and the other end is connected to the insole 2. The elastic support member 3 is placed in the groove 11 and can compress the air bag 4. Preferably, each elastic support member 3 and each vent hole 21 are matched one-to-one. That is, each elastic support member 3 can correspond to each vent hole 21, or each elastic support member 3 can be located near the corresponding vent hole 21. This way, when each elastic support member 3 is compressed, the vent hole 21 can be opened simultaneously. Specifically, when each elastic support member 3 is compressed, it compresses the corresponding vent hole 21 to open the gap of the vent hole 21. When each elastic support member 3 returns to its original state, the vent hole 21 closes.

[0025] In some examples, each elastic support 3 is made of rubber material, and the Shore hardness of each elastic support 3 is 30-40A. That is, the elastic support 3 is made of rubber material with a hard base and a relatively soft Shore hardness of 30-40A, which has good elasticity and resilience; or, each of the elastic support 3 is made of supercritical foam material, wherein when the elastic support 3 is made of supercritical foam material, its density is low and its resilience is good.

[0026] Each elastic support member 3 is shaped like a frustum of a cone, with its radius gradually increasing from the end connecting to the insole 2 to the end connecting to the midsole 1. This design makes the elastic support member 3 a frustum of a cone, tapering from bottom to top, thus better distributing pressure and improving support stability. Preferably, the upper surface of each elastic support member 3 is roughened; for example, the upper surface of each elastic support member 3 can be micro-roughened, such as by forming several particles to create a rough surface. This increases the friction on the upper surface of each elastic support member 3, preventing slippage during compression.

[0027] In some examples, the airbag 4 forms a recess, and the elastic support 3 is embedded in the recess of the airbag 4. This arrangement allows the elastic support 3 to deform more when it undergoes elastic deformation, thus causing most of the gas in the airbag 4 to be sprayed into the shoe cavity above the insole 2.

[0028] The height of the airbag 4 is greater than the depth of the groove 11. This design allows the airbag 4 to deform more when the insole 2 compresses it, thus causing most of the gas in the airbag 4 to be sprayed into the shoe cavity above the insole 2.

[0029] In some examples, a groove 11 is provided at the forefoot position of the midsole 1, and several elastic support members 2 are provided at the forefoot position of the midsole 1. The groove 11 and elastic support members 3 are located at the forefoot position of the midsole to allow for greater elastic deformation of the groove 11 and elastic support members 3, thereby compressing the airbag 4 to a greater degree, and thus causing most of the gas in the airbag 4 to be injected into the shoe cavity above the insole 2. Of course, the groove 11 can also be located at the heel position of the midsole 1, and the elastic support members 2 can be correspondingly located at the heel position of the midsole 1.

[0030] In some examples, each vent 21 is trapezoidal in shape, and the diameter of each vent 21 gradually decreases from bottom to top. The trapezoidal shape of the vent 21 helps guide airflow and improves ventilation efficiency; that is, the longitudinal cross-section of each vent 21 is trapezoidal, and the cross-sectional area of ​​the upper part of the same vent 21 is larger than that of the lower part. Preferably, to prevent dust and impurities from entering the insole 1, the walls of each vent 21 are connected to a dustproof mesh fabric. This dustproof mesh fabric does not affect the airflow through each vent 21. The mesh size of the dustproof mesh fabric is selected according to actual conditions and is not specified here. Existing dustproof filter yarn fabric can be selected as the dustproof mesh fabric.

[0031] This invention employs a breathable structure formed by an elastic support member 3, ventilation holes 21, and an airflow channel 42. When the foot presses down, the insole 2 compresses the airbag 4 under pressure, causing the gas in the airbag 4 to flow out from the outlet end and be ejected through the ventilation holes 21 of the insole 2 into the shoe cavity above the insole 2. That is, the gas in the airbag 4 is squeezed into the insole 2. When the downward pressure on the insole 2 is released, that is, when the foot is airborne, external air enters the airflow channel 42 through the one-way air inlet valve 41 and enters the airbag 4 through the airflow channel 42, so that the airbag 4 is filled with gas, which is then delivered to the shoe cavity again upon the next contact with the ground. The elastic support member 3 is set in the groove 11. Due to the setting of the elastic support member 3, its high elasticity accelerates the compression deformation of the sole and allows for rapid recovery, thereby ensuring the support stability and durability of the sole. When the elastic support member 3 undergoes elastic deformation, it compresses the airbag 4, thereby improving the circulation efficiency of the gas in the airbag 4.

[0032] like Figure 5 As shown, this utility model also discloses a heat-dissipating and breathable sports shoe, including the aforementioned sports shoe sole 100 and a breathable upper 200 disposed on the sports shoe sole 100. Furthermore, the aforementioned breathable upper 200 can be made of existing breathable materials, such as a mesh upper. A shoe cavity is formed between the breathable upper 200 and the insole 2.

[0033] When the foot presses down, the insole 2 compresses the airbag 4 under pressure, causing the gas in the airbag 4 to flow out from the outlet end and be ejected into the shoe cavity above the insole 2 through the ventilation hole 21. That is, the gas in the airbag 4 is squeezed into the insole 2. When the downward pressure on the insole 2 is withdrawn, that is, when the foot is off the ground, external air enters the airflow channel 42 through the one-way air inlet valve 41 and enters the airbag 4 through the airflow channel 42 to fill the airbag 4 with gas. When the foot touches the ground again, the gas is delivered to the shoe cavity. The elastic support 3 is set in the groove 11. Due to the setting of the elastic support 3, the compression deformation of the sole is accelerated and the sole recovers quickly through its own high elasticity, thereby ensuring the support stability and durability of the sole. When the elastic support 3 undergoes elastic deformation, it squeezes the airbag 4, thereby improving the circulation efficiency of the gas in the airbag 4.
