Description

Technical Field

[0001] This utility model relates to the field of footwear and apparel, specifically to a breathing massage cushioning insole and sole based on airbag interaction. Background Technology

[0002] As a vital weight-bearing and movement organ of the human body, the health and comfort of the feet are of paramount importance. Insoles, as the direct contact component between the foot and footwear, directly impact the user experience. Currently, insoles on the market face numerous technical limitations in terms of support, massage, cushioning, and breathability.

[0003] Firstly, traditional functional insoles are mostly made of a single material such as ethylene-vinyl acetate copolymer (EVA), memory foam, or silicone. These insoles provide overall support through pre-set static deformation, and their support strength and shape cannot be changed once manufactured. However, different areas of the foot (such as the ball of the foot, arch, and heel) experience significantly different pressure distributions and physiological needs when walking or standing. Traditional single-material insoles cannot achieve this differentiated, adaptive massage and support for different areas. Long-term use can easily lead to uneven pressure distribution on the sole of the foot, exacerbating local fatigue and even causing foot diseases.

[0004] Secondly, to improve comfort, insoles with air-cushion structures have emerged. However, most existing air-cushion insoles are single-cavity, integral inflation structures, or simply partitioned structures. This structure results in uniform internal air pressure, making it impossible to independently and precisely adjust pressure according to the biomechanical characteristics of different areas of the foot. Furthermore, the gas circulation in these insoles relies heavily on the micropores of the insole material itself or passive ventilation holes, leading to low air release efficiency and a lack of an active "breathing" mechanism. During prolonged wear, moisture generated by the feet is difficult to expel quickly, resulting in a stuffy and humid environment inside the shoe. This not only reduces comfort but also provides a breeding ground for bacteria, negatively impacting foot hygiene and health.

[0005] In summary, existing insoles suffer from the following core deficiencies: functionally, they cannot achieve zoned, differentiated dynamic massage and adaptive cushioning of the sole; and in terms of breathability, they lack an efficient active moisture-wicking mechanism. Therefore, there is an urgent need in this field for a novel insole and sole solution that requires no external energy, has a simple and lightweight structure, and can simultaneously achieve precise zoned massage, active cushioning adjustment, and efficient breathability and moisture wicking. Summary of the Invention

[0006] The purpose of this invention is to provide a breathing massage cushioning insole and sole based on airbag interaction, which aims to overcome the aforementioned problems existing in the prior art.

[0007] To achieve this objective, the present invention provides the following technical solution: A breathing massage cushioning insole based on airbag interaction includes an upper layer and a lower layer made of elastic material; the lower layer is fixed and sealed to the upper layer, forming a first cavity and a second cavity that are separated from each other; the upper layer has a foot-feeting surface in the first cavity and a heel-feeting surface in the second cavity; the upper layer has a plurality of first air holes connecting the first cavity to the outside and a plurality of second air holes connecting the second cavity to the outside; it also includes elastic protrusions, and the lower layer has a plurality of such elastic protrusions spaced apart inside the first cavity and / or inside the second cavity.

[0008] Furthermore, the sealing connection between the lower and upper layers is achieved through thermo-press sealing, and the upper layer forms a thermo-pressed surface around the first and second cavities.

[0009] Furthermore, the upper layer has a first transition surface formed at the edge of the foot-stepping surface, and the first transition surface is provided with a plurality of the first air holes; the upper layer has a second transition surface formed at the edge of the heel-stepping surface, and the second transition surface is provided with a plurality of the second air holes.

[0010] Furthermore, the upper end of the first air hole is angled towards the outer side of the foot tread surface.

[0011] Furthermore, the upper end of the aforementioned second air hole is angled towards the outer side of the heel-stepping surface.

[0012] Furthermore, the aforementioned first transition surface surrounds the entire foot tread surface, and multiple first air holes are arranged at intervals around the entire first cavity; the aforementioned second transition surface surrounds the entire heel tread surface, and multiple second air holes are arranged at intervals around the entire second cavity.

[0013] Furthermore, when the upper layer is not compressed or dented by external force, the upper end of the aforementioned elastic protrusion separates from the upper layer.

[0014] Furthermore, the lower layer is provided with multiple elastic protrusions spaced apart inside both the first cavity and the second cavity.

[0015] Furthermore, the aforementioned elastic protrusion is an elastic capsule or an elastic solid.

[0016] A breathable massage cushioning sole based on airbag interaction includes a sole body; and also includes a breathable massage cushioning insole based on airbag interaction with the structure described in any one of the above, with the lower layer fixedly connected to the upper surface of the sole body.

[0017] Compared with the prior art, this utility model has the following advantages: The airbag interactive breathing massage cushioning insole provided by this utility model achieves multiple beneficial effects, integrating dynamic adaptive massage, active breathing and exhaust, and efficient cushioning and shock absorption, compared with the prior art. Moreover, it requires no external energy and has a lightweight structure.

[0018] Specifically, its beneficial effects are as follows: First, it achieves dynamic adaptive massage. When the foot steps on the ground, the cavity (first or second cavity) is compressed, and the internal gas, while being expelled from the air vent (first or second air vent), pushes the elastic protrusion towards the sole of the foot, forming a pulse-like pressure. When the foot is lifted, the cavity rebounds under the action of elastic reset and negative pressure, completing one massage cycle. This process continues with walking, achieving dynamic and cyclical massage of the sole of the foot.

[0019] Secondly, it creates an active "breathing" moisture-wicking mechanism. During the compression phase of stepping, the humid air inside the cavity is forcibly expelled into the shoe and even outside; during the pressure-relieving phase of lifting the foot, the cavity forms a negative pressure, drawing in fresh air from the outside. This "breathing in and out" action, driven by walking power, creates a continuous micro-airflow circulation between the insole and the inside and outside of the shoe, effectively removing sweat from the soles of the feet, fundamentally improving the hot and humid environment inside the shoe, and significantly enhancing the dryness and hygiene of the footwear.

[0020] Furthermore, it offers superior layered cushioning performance. Through the synergistic effect of the upper and lower cavities and multiple elastic protrusions within the cavities, a multi-layered cushioning system is constructed. This design effectively disperses impact forces on the foot and absorbs high-frequency vibrations during exercise, providing better protection for the feet and knees.

[0021] Finally, the overall design boasts significant practical advantages. The insole is entirely powered by the mechanical energy of walking, requiring no electricity or manual inflation, and incurring no maintenance costs. Simultaneously, its significantly reduced weight ensures lightweight comfort and a natural gait, while also offering excellent elasticity and durability. Attached Figure Description

[0028] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Many details are described below to provide a comprehensive understanding of this utility model; however, those skilled in the art can implement this utility model without these details.

[0029] Example 1 like Figures 1 to 4 As shown, a breathing massage cushioning insole based on airbag interaction includes an upper layer 2, a lower layer 1, and multiple elastic protrusions 4. The lower layer 1 is fixedly and sealed to the upper layer 2, forming a first cavity 3 and a second cavity 5 that are separated from each other, acting as two large airbags. The upper layer 2 has a foot-feeding surface 23 in the first cavity 3 and multiple first air holes 230 connecting the first cavity 3 to the outside. The upper layer 2 has a heel-feeding surface 25 in the second cavity 5 and multiple second air holes 250 connecting the second cavity 5 to the outside. The lower layer 1 has multiple elastic protrusions 4 spaced apart both inside the first cavity 3 and the second cavity 5. Alternatively, in other embodiments, the lower layer 1 may only have multiple elastic protrusions 4 spaced apart inside the first cavity 3 or only inside the second cavity 5.

[0030] like Figures 1 to 4 As shown, the upper layer 2 is made of elastic material, including but not limited to TPU material, to ensure that the foot tread surface 23 or heel tread surface 25 can automatically elastically recover after the external force is removed when it is squeezed and dented.

[0031] Preferably, the upper surface of the lower layer 1 is covered with a breathable surface layer (not shown in the figure), which includes, but is not limited to, breathable mesh fabric.

[0032] like Figures 1 to 4 As shown, in this embodiment, the sealing connection between the lower layer 1 and the upper layer 2 is achieved by thermocompression sealing, and the upper layer 2 forms a thermocompression surface 21 on the periphery of the first cavity 3 and the second cavity 5. Preferably, both the upper layer 2 and the lower layer 1 are made of TPU material, which is beneficial for achieving high-quality thermocompression sealing.

[0033] Of course, in other embodiments, the lower layer 1 and the upper layer 2 can also be sealed together by other conventional methods, such as adhesive bonding.

[0034] like Figures 1 to 4As shown, in this embodiment, the upper layer 2 has a first transition surface 231 formed at the edge of the foot-feeding surface 23. The first transition surface 231 is provided with a plurality of first air holes 230 to reduce the entry of foreign objects into the air holes while ensuring air circulation. In other embodiments, the first air holes 230 may also be provided on the foot-feeding surface 23.

[0035] Similarly, the upper layer 2 has a second transition surface 251 formed at the edge of the heel-treading surface 25. This second transition surface 251 is provided with a plurality of second air holes 250 to reduce the entry of foreign objects into the air holes while ensuring air circulation. In other embodiments, the second air holes 250 may also be provided on the heel-treading surface 25.

[0036] Preferably, the first transition surface 231 surrounds the entire foot tread surface 23, and a plurality of first air holes 230 are arranged at intervals around the entire first cavity 3; the second transition surface 251 surrounds the entire heel tread surface 25, and a plurality of second air holes 250 are arranged at intervals around the entire second cavity 5.

[0037] Preferably, the diameter of the first pore 230 and the second pore 250 is 0.1mm-1mm.

[0038] like Figures 1 to 4 As shown, in this embodiment, the upper end of the first air hole 230 is obliquely arranged towards the outer side of the foot-stepping surface 23 to further reduce the entry of foreign objects into the air hole while ensuring air circulation. Preferably, the first air hole 230 is at a horizontal angle of 30°-40°, preferably 30°.

[0039] Similarly, in this embodiment, the upper end of the second vent 250 is angled towards the outer side of the heel step surface 25 to further reduce the entry of foreign objects into the vent while ensuring airflow. Preferably, the second vent 250 forms an angle of 30°-40° with the horizontal direction, preferably 30°.

[0040] like Figures 1 to 4 As shown, in this embodiment, the elastic protrusion 4 is an elastic capsule, that is, a hollow capsule structure made of elastic material, with its lower end fixedly connected to the lower layer 1, and the elastic protrusion 4 acts as a small air bladder. Preferably, the elastic protrusion 4 is integrally formed with the lower layer 1, but it is not excluded that the elastic protrusion 4 can also be fixedly connected to the lower layer 1 by means of gluing or other methods. In addition, in other embodiments, the elastic protrusion 4 can also be an elastic solid body, that is, a solid structure made of elastic material.

[0041] like Figures 1 to 4 As shown, in this embodiment, when the upper layer 2 is not compressed or dented by external force, the upper end of the elastic protrusion 4 is separated from the upper layer 2. Of course, in other embodiments, when the upper layer 2 is not compressed or dented by external force, the upper end of the elastic protrusion 4 can also be detachably abutted against the upper layer 2.

[0042] like Figures 1 to 5 As shown, the working principle of this utility model is as follows: A. Dynamic massage effect: During walking, the forefoot and heel repeatedly and alternately apply pressure to the forefoot tread surface 23 and the heel tread surface 25, causing the first cavity 3 and the second cavity 5 to be repeatedly and alternately compressed and indented. Taking the forefoot tread surface 23, the first cavity 3, and the elastic protrusion 4 inside as an example, when the forefoot tread surface 23 is compressed and moved downward, the first cavity 3 is compressed and indented. At the same time, the gas inside the cavity is discharged through the first air hole 230, and the gas inside the cavity compresses and pushes the elastic protrusion 4 to protrude towards the forefoot tread surface 23. Combined with the downward movement of the forefoot tread surface 23, the elastic protrusion 4 forms a pulse-like pressure on the forefoot. When the forefoot is lifted, the forefoot tread surface 23 returns to its original position under its own elastic force, forming negative pressure. At the same time, the elastic protrusion 4 rebounds and returns to its original position with the assistance of negative pressure, completing one massage cycle and realizing adaptive pressure adjustment.

[0043] Furthermore, if the elastic protrusion 4 is placed on key acupoints on the sole of the foot (such as the Yongquan acupoint), it can achieve a targeted massage effect, promote blood circulation in the sole of the foot, and relieve problems such as plantar fasciitis and foot fatigue. Unlike traditional fixed-shape massage protrusions, it is more adaptable.

[0044] B. Breathing effect (taking the foot tread surface 23, the first cavity 3 and its internal elastic protrusion 4 as an example): B1. Compression stage: When the forefoot is pressed down and pressure is applied, the gas in the first cavity 3 is discharged through the first air hole 230. The discharged gas diffuses into the space inside the shoe and even into the space outside the shoe. B2. Release phase: When the forefoot is lifted and the pressure disappears, the first cavity 3 forms a negative pressure, and fresh air is drawn in from the gap between the inner and outer spaces of the shoe through the first air hole 230, forming a micro-airflow circulation of "insole-inner shoe-outer shoe", reducing sweat retention. C. Cushioning and shock absorption (taking the foot tread surface 23, the first cavity 3 and its internal elastic protrusion 4 as an example): The independent deformation of multiple elastic protrusions 4 disperses the local impact force on the sole of the foot, and the volume change of the first cavity 3 absorbs high-frequency vibrations during walking / movement, thereby achieving a layered buffering effect and reducing pressure on the foot and knee joints.

[0045] Furthermore, this invention requires no electricity or manual inflation, and achieves automatic response through a purely mechanical structure, resulting in no maintenance costs. It also possesses good elasticity and durability, and is not easily deformed after long-term use. Compared to electric massage insoles, it reduces weight by about 60%, conforming to lightweight design (overall weight of size 42 ≤ 30g), and does not affect normal walking gait.

[0046] Example 2 like Figures 1 to 6 As shown, a breathable massage cushioning sole based on airbag interaction includes a sole body 6 and a breathable massage cushioning insole with the structure described above, wherein the lower layer 1 of the insole is fixedly connected to the upper surface of the sole body 6. Preferably, the lower layer 1 is fixedly bonded to the upper surface of the sole body 6 with adhesive. The sole body 6 is a conventional sole, and its specific structure will not be described in detail here. Those skilled in the art can select conventional soles with different layer structures or materials as needed during implementation.

[0047] The above are merely specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
