Description

Technical Field

[0001] This utility model belongs to the field of shoe sole technology, and relates to a children's shoe sole. Background Technology

[0002] Shoes are common clothing items in people's lives, usually used to wrap the feet and protect them from being punctured by sharp objects on the ground. At present, most of the breathable shoes on the market (such as children's shoes, sports shoes, etc.) rely on the upper for ventilation, while the sole does not have a breathable function. Because the space under the feet is relatively closed, it is difficult to dissipate heat. After a long period of exercise, the heat under the feet cannot be dissipated quickly, which makes the feet often feel stuffy and hot.

[0003] The existing patent document with authorization publication number CN222264539U discloses a breathable sports shoe sole, including a shoe plate, an air inlet, an air outlet, a controller, a power supply, and a fan. The surface of the shoe plate is provided with a replacement device, which includes a screw threadedly connected to the surface of the shoe plate. A handle is slidably connected to the arc surface of the screw, and a sliding plate is connected to the surface of the handle. A groove is formed on the surface of the shoe plate, and a fixing block is connected to the surface of the sliding plate. The fixing block is slidably connected to the inner wall of the groove. A telescopic rod is connected to the surface of the fixing block, and the other end of the telescopic rod is connected to the inner wall of the groove. A groove is formed on the surface of the sliding plate, and the inner wall of the groove is connected to the fan.

[0004] However, the aforementioned existing technologies still have the following shortcomings:

[0005] 1. Poor waterproof sealing, which easily leads to water entering the shoe: The air vents of this technology are directly opened on the outside of the shoe plate, and the air inlets are also directly connected to the outside. When the user walks on rainy, flooded, or low-lying wet and slippery roads, sewage can easily flow back into the cavity of the sole under external pressure through the air vents and air inlets, and further seep into the shoe, causing socks and shoe lining to get wet, seriously affecting the comfort of wearing the shoes, and may cause hygiene problems.

[0006] 2. Inadequate structural design severely compromises shock absorption: To accommodate the fan and complex mechanical replacement mechanism, a large amount of space must be created within the shoe plate, and rigid structural components must be installed. This prevents the sole from effectively deforming and dispersing energy upon impact, significantly reducing its inherent cushioning and shock absorption performance, thus affecting athletic protection and wearing experience. Utility Model Content

[0007] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a children's shoe sole that solves the technical problems mentioned in the background art, such as poor waterproof sealing, easy water ingress into the shoe, and mediocre shock absorption.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A children's shoe sole includes a sole body, an air bladder is provided inside the forefoot area of ​​the sole body, a plurality of spring plates for providing rebound support are fixedly connected inside the air bladder, a cushioning cavity is provided inside the arch area of ​​the sole body, and a plurality of air inlets extending through to the upper surface of the sole are provided on the upper wall of the cushioning cavity.

[0010] An air collection chamber is provided inside the forefoot area of ​​the sole body;

[0011] One end of the air collection chamber extends and is integrated into the upturned structure at the very front of the sole. Several air outlets communicating with the air collection chamber are provided on the inner wall of the upturned structure and the upper surface of the forefoot area of ​​the sole body.

[0012] The air outlet of the airbag is connected to the air collection chamber through a flexible air delivery tube with a built-in one-way air outlet valve.

[0013] The buffer chamber is connected to the air inlet of the airbag via a soft suction tube with a built-in one-way air inlet valve.

[0014] Furthermore, both the buffer chamber and the gas collection chamber are connected to multiple elastic support blocks.

[0015] Furthermore, the elastic support block is made of a highly resilient polymer material, namely thermoplastic polyurethane.

[0016] Furthermore, the arch area of ​​the sole body is provided with an irregularly shaped carbon plate, which is located below the cushioning cavity.

[0017] Furthermore, a cushioning air cushion is embedded in the heel area of ​​the sole body.

[0018] Furthermore, the upper surface of the sole body is provided with a first anti-slip texture to increase the friction between the insole and the sole.

[0019] Furthermore, the bottom of the sole body is provided with a second anti-slip pattern to increase friction with the ground.

[0020] The beneficial effects of this utility model are as follows:

[0021] 1. Effectively improves the waterproof and stain-resistant performance of the sole. This invention places both the air vent and the air inlet on the inner wall of the upturned toe structure and the upper surface of the sole body. This ensures that, during actual use, both the air vent and the air inlet are located inside the shoe. Due to the shielding effect of the shoe upper and its height advantage, this location effectively prevents most splashes of water and dust from directly entering the shoe, significantly reducing the risk of water entering the shoe and ensuring children stay dry and hygienic in various road conditions.

[0022] 2. This utility model employs a complete airflow design, from the buffer chamber to the one-way inlet valve to the air bladder to the one-way outlet valve to the air collection chamber, and combines this with the control of the one-way valve to ensure that the airflow flows in a single direction. When the foot is pressed down, the air bladder compresses, and waste gas is discharged from the air collection chamber; when the foot is lifted, the air bladder recovers under the action of the spring plate and draws in air from the arch area, thereby achieving continuous air renewal inside the shoe. Combined with the excellent breathability of the shoe's upper, this continuously expels gas from inside the shoe to the outside, enhancing the airflow throughout the entire shoe and improving the comfort of wearing the shoe.

[0023] 3. The core driving force of this utility model comes from the natural pressing action of the forefoot against the airbag during walking. The airbag and its internal spring plate constitute part of the forefoot cushioning system. While absorbing impact and providing a rebound feel, its compression and recovery process provides power for air circulation. This means that the ventilation function does not require additional cushioning space, but rather utilizes the original cushioning structure, solving the technical problem of the contradiction between ventilation and shock absorption functions.

[0024] 4. Simple and reliable structure, passive operation, and low cost. This application completely eliminates the electronic and precision mechanical components such as controllers, power supplies, fans, and replacement devices found in existing technologies, consisting only of an airbag, cavity, pipes, and a one-way valve. The entire system requires no electricity and is driven naturally by the human gait, greatly simplifying the structure. This not only significantly reduces manufacturing costs and failure rates but also improves the product's durability and reliability, making it ideal for children with high activity levels.

[0033] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0034] like Figure 1-6 As shown, a children's shoe sole includes a sole body 1. An air bladder 2 is disposed inside the forefoot area of ​​the sole body 1. Multiple spring plates 3 for providing rebound support are fixedly connected inside the air bladder 2. A cushioning cavity 4 is formed inside the arch area of ​​the sole body 1. Multiple air inlets 5 extending to the upper surface of the sole are formed on the upper wall of the cushioning cavity 4. An air collecting cavity 6 is formed inside the forefoot area of ​​the sole body 1. One end of the air collecting cavity 6 extends and is integrated into the upturned toe structure at the very front of the sole. The inner wall of the structure and the upper surface of the forefoot area of ​​the sole body 1 are provided with several air outlets 7 that communicate with the air collection chamber 6. The air outlet of the airbag 2 is connected to the air collection chamber 6 through a soft air delivery tube 9 with a built-in one-way air outlet valve 8. The buffer chamber 4 is connected to the air inlet of the airbag 2 through a soft air intake tube 11 with a built-in one-way air intake valve 10. Both the buffer chamber 4 and the air collection chamber 6 are connected to a number of elastic support blocks 12. The elastic support blocks 12 are made of a highly resilient polymer material, which is thermoplastic polyurethane.

[0035] The elastic support blocks 12 (made of high-molecular materials such as thermoplastic polyurethane) inside the buffer chamber 4 and the gas collection chamber 6 ensure that the chambers will not completely collapse and stick together when subjected to force, and always maintain a smooth airflow channel. At the same time, their high resilience also helps the chamber structure to recover quickly, ensuring the stability and durability of the system.

[0036] When a child walks, their foot lands on the ground, and the forefoot area is compressed. The air bladder 2 inside the forefoot area deforms under the vertical pressure of the foot, reducing its internal volume and causing a sudden increase in air pressure. During this process, multiple spring plates 3 inside the air bladder 2 are simultaneously bent, storing elastic potential energy. The high-pressure gas inside the air bladder 2 forces open the one-way vent valve 8 connected to its vent end. The compressed gas is then forcibly transported to the air collection chamber 6 through the soft air delivery tube 9, and finally discharged from the vent holes 7 on the inner wall of the upturned toe structure and the upper surface of the forefoot. Since the overall temperature inside the shoe is relatively uniform, the gas blown towards the toes and forefoot will not cause the feet to sweat. The temperature of the blown gas is not high enough to cause sweating or discomfort. The blown gas will be discharged through the shoe's upper.

[0037] As the foot moves forward and the heel lifts, the pressure on the forefoot is released. Upon release, the compressed spring plate 3 releases its stored elastic potential energy, quickly rebounding to its original shape. This causes the air bladder 2 to inflate, creating negative pressure inside. The negative pressure suction within the air bladder 2 acts on the one-way air intake valve 10 connected to its intake end, opening it. Air from the arch area enters the cushioning chamber 4 through the air intake hole 5 on the upper surface of the arch area cushioning chamber 4. Then, under the action of negative pressure suction, it is drawn into the recovering air bladder 2 through the soft suction tube 11, preparing for the next compression and exhaust. This continuous renewal of air inside the shoe, combined with the shoe's breathable upper, continuously expels air from the shoe to the outside, enhancing airflow throughout the entire shoe and improving comfort when wearing the shoe.

[0038] like Figure 1 , 7As shown, a shaped carbon plate 13 is provided inside the arch area of ​​the sole body 1, and the shaped carbon plate 13 is located below the cushioning cavity 4. By setting the shaped carbon plate 13 inside the arch area and placing it below the cushioning cavity 4, the extremely high torsional stiffness of the shaped carbon plate 13 can greatly enhance the stability of the midfoot in the sole, prevent excessive deformation of the arch during exercise, and provide good protection for the healthy development of children's arches. At the same time, it connects the forefoot and heel more firmly, optimizes the force transmission efficiency, makes the stride more stable, and further improves the overall performance and safety protection level of the sole. A cushioning air cushion 14 is embedded inside the heel area of ​​the sole body 1. The upper surface of the sole body 1 is provided with a first anti-slip texture 15 to increase the friction between the insole and the sole, and the bottom of the sole body 1 is provided with a second anti-slip texture 16 to increase the friction with the ground. By setting a first anti-slip pattern 15 on the upper surface of the sole body 1 and a second anti-slip pattern 16 on the bottom, the anti-slip pattern on the upper surface can effectively prevent the insole from sliding inside the shoe, ensuring stable strides; the anti-slip pattern on the bottom greatly enhances the friction between the shoe and various surfaces, preventing children from slipping and falling while running or turning, and greatly improving sports safety.

[0039] The working principle of this utility model is as follows:

[0040] When a child walks, their feet land on the ground, and the forefoot area is compressed by force:

[0041] The airbag 2 inside the forefoot area deforms under the vertical pressure of the foot, its internal volume decreases and the air pressure increases. During this process, multiple spring plates 3 inside the airbag 2 are simultaneously bent and store elastic potential energy.

[0042] The high-pressure gas inside the airbag 2 breaks open the one-way air valve 8 connected to its air outlet end. The high-pressure gas is forced to be transported into the air collection chamber 6 through the soft air delivery tube 9, and finally discharged from the air outlet 7 on the inner wall of the upturned structure of the shoe toe and the upper surface of the forefoot.

[0043] As you take a step forward, lift your heel, and release pressure on your forefoot:

[0044] After the pressure on the forefoot is released, the compressed spring plate 3 releases its stored elastic potential energy, quickly rebounds to its original shape, and causes the airbag 2 to inflate, creating negative pressure inside it. The negative pressure suction inside the airbag 2 acts on the one-way air intake valve 10 connected to its air intake end, opening it.

[0045] Air from the arch area enters the cushioning chamber 4 through the air inlet 5 on the upper surface of the arch area cushioning chamber 4, and then, under the action of negative pressure suction, is drawn into the recovering airbag 2 through the soft suction tube 11, preparing for the next compression and exhaust.

[0046] This allows for continuous air renewal inside the shoe. Combined with the shoe's breathable upper, it constantly expels air from inside the shoe to the outside, enhancing airflow throughout the shoe and thus improving comfort when wearing it.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
