Description

Technical Field

[0001] The invention relates to the technical field of soles, and in particular to a shock-absorbing and buffering sole for releasing sole pressure. Background Art

[0002] Air shock-absorbing sole technology is widely used in various sports shoes, such as running shoes, basketball shoes, football shoes, tennis shoes, etc., to meet the needs of different sports scenes. For example, in basketball shoes, air cushion technologies such as Zoom Air and Max Air provide athletes with excellent cushioning and support performance; in running shoes, technologies such as Air Sole and LunarLite focus more on lightweight and comfort. The core principle of air shock-absorbing sole technology is to use the compression and rebound characteristics of gas to absorb and disperse the impact force during exercise, thereby reducing the burden on the feet and joints. Specifically, by building a sealed air chamber or air bag into the sole, when the foot touches the ground, the gas is compressed and stores energy; then, as the pressure is released, the gas rebounds, providing upward support and achieving a shock-absorbing effect.

[0003] However, most existing air shock-absorbing insoles use compressed air to reduce shock. When air is compressed, its resistance gradually increases, which greatly reduces the shock-absorbing effect. At the same time, the air bag setting will reduce the strength of the shoes. At the same time, repeated compression of the air bag will reduce the durability of the sole, which will greatly reduce the life of the shoes. Summary of the invention

[0004] In view of the above problems, the present invention aims to solve the above problems. One object of the present invention is to provide a shock-absorbing and cushioning sole for releasing the pressure on the sole of the foot, which can ensure strong support for the shoes and at the same time, the air slow release has a good shock-absorbing effect.

[0005] The solution adopted in this embodiment is: a shock-absorbing and buffering sole for releasing sole pressure, comprising a foamed elastic sole body, wherein the elastic sole body is provided with an elastic groove at least at the heel, and the elastic groove transversely penetrates the elastic sole body; at least one air suspension component is provided in the elastic groove, and the air suspension component is provided with an air bag and a switching rod, and an exhaust cavity and an air intake cavity are provided in the elastic sole body from bottom to top along the thickness direction; when the foot squeezes the sole, the switching rod closes the air intake cavity, and the exhaust cavity is connected to the air bag; when the foot is lifted, the exhaust cavity and the air intake cavity are both connected to the air bag.

[0006] In order to ensure stable ventilation, a sealing ring is provided on the top of the switching rod, and a slide groove is provided on the elastic sole body perpendicular to the thickness direction. The slide groove connects the exhaust chamber, the air intake chamber and the air bag. The switching rod is slidably connected in the slide groove. There is a gap between the switching rod and the slide groove, and the diameter of the sealing ring is larger than the diameter of the slide groove.

[0007] In order to effectively increase the elasticity and durability of the sole itself, the air suspension assembly includes an outer elastic frame, which is arranged in a wavy line, and corrugated elastic support plates are arranged on both sides of the outer elastic frame. At least one switching rod is arranged between the corrugated elastic support plates, and one end of the switching rod is fixedly connected to the bottom of the outer elastic frame; the top and top of the outer elastic frame are respectively fixedly connected to the inner wall of the elastic groove.

[0008] The air bag is integrated with the peripheral elastic frame. The peripheral elastic frame is provided with a diaphragm along the length direction of the sole. The diaphragm separates each switching rod separately. The air bag is formed between the diaphragm and the peripheral elastic frame. An opening is provided at the top of the peripheral elastic frame. The switching rod is inserted into the exhaust cavity and the air intake cavity through the opening.

[0009] A preferred technical solution is that the thickness of the peripheral elastic frame is greater than the thickness of the diaphragm, and the thickness of the diaphragm is 0.5-2 mm.

[0010] In order to ensure strong support and ventilation function, the peripheral elastic frame, elastic sole body and switch rod are all made of elastic materials. The hardness of the peripheral elastic frame is greater than that of the elastic sole body, and the hardness of the switch rod is greater than that of the peripheral elastic frame.

[0011] Preferably, the exhaust cavity and the air intake cavity extend along the width direction of the elastic sole body, and both the exhaust cavity and the air intake cavity extend to the side wall of the elastic sole body. The elastic sole body is provided with exhaust pores connected to the exhaust cavity, and the elastic sole body is provided with air intake holes connected to the air intake cavity.

[0012] Furthermore, the diameter of the exhaust pore is smaller than that of the air inlet pore, the diameter of the exhaust pore is 1-5 mm, and the diameter of the air inlet pore is 5-20 mm.

[0013] A preferred technical solution is that the air inlet hole is located on the side wall of the elastic sole body and communicates with the outside, or the air inlet hole is located on the top of the elastic sole body and communicates with the inside of the shoe.

[0014] Furthermore, the cross-sections of the exhaust cavity and the intake cavity become smaller as they are closer to the switching rod.

[0015] Compared with the prior art, the shock-absorbing and cushioning sole for releasing the sole pressure of the present invention has the following technical effects: 1.

[0019] In order to make the purpose, technical scheme and advantages of the embodiments of the present invention clearer, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. It should be noted that the embodiments in this application and the features in the embodiments can be combined with each other arbitrarily without conflict.

[0020] The shock-absorbing and cushioning sole for releasing the pressure on the sole of the foot is described in detail below in conjunction with the accompanying drawings and embodiments.

[0021] like Figure 1 , Figure 2 As shown, the present invention provides a shock-absorbing and buffering sole for releasing sole pressure, comprising a foam-molded elastic sole body 1. The foam-molded elastic sole body 1 has excellent resilience and durability, and can effectively absorb the impact force generated when walking or running. The elastic sole body 1 is provided with an elastic groove 11 at least at the heel, and the elastic groove 11 runs through the elastic sole body 1 horizontally. The design of the elastic groove 11 allows the sole to deform when under pressure, thereby absorbing energy and achieving a shock-absorbing effect. At least one air suspension component 2 is provided in the elastic groove 11, and the air suspension component 2 is provided with an air bag 6 and a switching rod 22. When the foot squeezes the sole, the air bag 6 is compressed to absorb the impact force; and when the foot is lifted, the air bag 6 returns to its original state, releases energy, and prepares for the next step. This design not only improves the shock-absorbing effect, but also extends the service life of the sole. The air bag 6 effectively absorbs the force of the sole stepping on, and effectively absorbs and disperses the impact force during movement. The elastic sole body 1 is provided with an exhaust chamber 4 and an air intake chamber 3 from bottom to top along the thickness direction. The design of these two chambers enables the air bag 6 to be inflated and deflated according to the movement of the foot, thereby achieving a dynamic shock-absorbing effect. When the foot squeezes the sole, the switching rod 22 closes the air intake chamber 3. At the same time, the exhaust chamber 4 is connected to the air bag 6, allowing the gas in the air bag 6 to be discharged. The exhaust speed of the exhaust chamber 4 is relatively slow, so that the internal pressure of the air bag 6 will not increase sharply when it is compressed. By slowly releasing the internal air, the pressure release is more relaxed, achieving the purpose of shock absorption. When the foot is lifted, the exhaust chamber 4 and the air intake chamber 3 are both connected to the air bag 6, and the air bag 6 is re-inflated to prepare for the next step.

[0022] In order to ensure stable ventilation, a sealing ring 221 is provided on the top of the switching rod 22, which effectively prevents gas leakage and ensures the stability of the shock absorption effect. At the same time, the elastic sole body 1 is provided with a slide groove 5 perpendicular to the thickness direction. The design of the slide groove 5 enables the switching rod 22 to slide smoothly therein, thereby realizing effective connection and disconnection between the air intake chamber 3 and the exhaust chamber 4 and the air bag 6. There is a gap between the switching rod 22 and the slide groove 5, which ensures that the switching rod 22 can slide freely without hindrance, and the gas can be effectively discharged. The design that the diameter of the sealing ring 221 is larger than the diameter of the slide groove 5 further enhances the sealing effect and prevents gas leakage. When the foot steps on the elastic sole body 1, the insole itself and the air suspension component 2 will deform first, and the switching rod 22 has a large hardness and the end is not fixed. The top of the switching rod 22 moves toward the air intake chamber 3, and the sealing ring 221 blocks the air intake chamber 3, so that the gas of the air bag 6 can only be slowly discharged through the exhaust pores 41 of the exhaust chamber 4 when compressed, so that the air bag 6 can provide a stable buffering force.

[0023] In order to effectively increase the elasticity and durability of the sole itself, the air suspension assembly 2 includes a peripheral elastic frame 21. The peripheral elastic frame 21 is arranged in a wavy line, which not only improves the elasticity of the sole, but also increases its fatigue resistance. Both sides of the peripheral elastic frame 21 are provided with corrugated elastic support plates 211, which together with the peripheral elastic frame 21 constitute a stable support structure, effectively preventing the sole from being deformed or damaged when subjected to force. The peripheral elastic frame 21 adopts an elastic material with better toughness, so that it is still not easy to be damaged when repeatedly deformed, such as TPU material. At the same time, at least one switching rod 22 is arranged between the corrugated elastic support plates 211, one end of the switching rod 22 is fixedly connected to the bottom of the peripheral elastic frame 21, and the other end is inserted into the exhaust cavity 4 and the air intake cavity 3, realizing the inflation and deflation functions of the air bag 6. The top and bottom of the peripheral elastic frame 21 are bonded to the top and bottom of the elastic groove 11, so that the force applied to the elastic sole body 1 can be effectively transmitted to the peripheral elastic frame 21.

[0024] The integrated design of the air bag 6 and the peripheral elastic frame 21 is another major innovation. This design not only simplifies the structure, but also improves the shock absorption effect. The peripheral elastic frame 21 is provided with diaphragms 23 along the length direction of the sole. These diaphragms 23 separate each switching rod 22 separately, preventing the mutual influence between the air bags 6. At the same time, a space for the air bag 6 is formed between the diaphragm 23 and the peripheral elastic frame 21, so that the air bag 6 can expand and contract freely. The opening set at the top of the peripheral elastic frame 21 allows the switching rod 22 to pass through and be inserted into the exhaust cavity 4 and the air intake cavity 3, realizing the inflation and deflation functions of the air bag 6.

[0025] The preferred technical solution is that the thickness of the peripheral elastic frame 21 is greater than the thickness of the diaphragm 23. This design not only improves the strength and durability of the sole, but also ensures the stability and sealing of the air bag 6. At the same time, the thickness of the diaphragm 23 is selected within the range of 0.5-2mm, which not only ensures sufficient strength but also avoids the decrease in flexibility caused by excessive thickness.

[0026] In order to ensure strong support and ventilation function, the peripheral elastic frame 21, the elastic sole body 1, and the switch rod 22 are all made of elastic materials. The selection of these materials not only improves the elasticity and comfort of the sole, but also ensures the stability and durability of the shock absorption effect. At the same time, the hardness of the peripheral elastic frame 21 is greater than that of the elastic sole body 1. This design enables the peripheral elastic frame 21 to bear more pressure and maintain the stability of the sole; and the hardness of the switch rod 22 is greater than that of the peripheral elastic frame 21, ensuring the stability and durability of the switch rod 22 during the sliding process.

[0027] Preferably, the exhaust cavity 4 and the air inlet cavity 3 extend along the width direction of the elastic sole body 1 and extend to the side wall of the elastic sole body 1. This design not only simplifies the structure but also improves the ventilation efficiency. At the same time, the elastic sole body 1 is provided with exhaust pores 41 connected to the exhaust cavity 4 and air inlet pores 31 connected to the air inlet cavity 3. The design of these holes allows air to smoothly enter and exit the sole to achieve an effective shock absorption effect, and the air is slowly released through the exhaust pores 41, so that the resistance of the air bag 6 will not increase sharply when it is squeezed, so that the buffering effect is better.

[0028] Further, the diameter of the exhaust pores 41 is smaller than the diameter of the air inlet 31. This design not only prevents dust and debris from entering the sole but also ensures the smoothness of exhaust. Specifically, the diameter of the exhaust pores 41 is 1-5mm and the diameter of the air inlet 31 is 5-20mm. Such size selection not only ensures sufficient ventilation but also avoids the structural strength reduction caused by too large holes. The preferred technical solution is that the air inlet 31 can be located on the side wall of the elastic sole body 1 and communicate with the outside world or located on the top of the elastic sole body 1 and communicate with the inside of the shoe. This design not only improves the air permeability and comfort of the sole but also allows users to adjust and select according to their needs. When the air inlet 31 is located on the side wall of the elastic sole body 1, external air can be quickly introduced into the air bag 6 when resetting. At this time, the aperture of the air inlet 31 can be selected to be about 6mm. When it is located on the top of the elastic sole body 1 and communicated with the inside of the shoe, ventilation inside the shoe can be achieved. Since there is also an insole, the diameter of the air inlet needs to be increased to 20mm so that the air circulation speed is sufficient during ventilation.

[0029] Furthermore, the cross-sections of the exhaust chamber 4 and the intake chamber 3 are smaller as they are closer to the switch rod 22. This design not only improves the ventilation efficiency but also ensures the stability and durability of the switch rod 22 during the sliding process. At the same time, this cross-section change design also reduces the resistance of the gas during the flow process, thereby further improving the shock absorption effect. At the same time, it also ensures that the ventilation rod can be quickly turned on and off.
