Description

Technical Field

[0001] This utility model belongs to the field of shoe sole technology, and in particular relates to a high-resilience ultralight shoe sole. Background Technology

[0002] The sole is the bottom part of a shoe that contacts the ground; it's the component in the shoe's structure that directly interacts with the ground. The sole protects our feet from sharp objects and temperature changes (such as icy or scalding surfaces). The material and tread pattern of the sole provide traction to prevent slipping while walking or exercising, and it also absorbs the impact of the ground on the feet when walking or running, reducing fatigue and the risk of injury.

[0003] For example, CN220403250U discloses an ultralight high-rebound midsole and shoe, including an upper and a sole. The sole is located at the bottom of the upper and includes an outsole and a midsole. The midsole includes an upper cushioning layer and a lower cushioning layer arranged vertically. The lower cushioning layer has a perforated groove on its front side, which extends horizontally through the lower cushioning layer. A supporting carbon plate is provided between the perforated grooves. A rear cushioning component is provided on the rear side of the lower cushioning layer. The rear cushioning component includes a support layer, an outer layer, and cushioning pillars. The support layer is located on the upper and lower sides of the outer layer, and the cushioning pillars are located inside the outer layer. This utility model belongs to the field of sports shoes, specifically featuring a double-layer cushioning structure. Through mechanical and structural cushioning mechanisms, it can provide a high cushioning and rebound effect during strenuous exercise. With the air cushion setting, it can also improve comfort during non-strenuous exercise, thus making it suitable for various sports scenarios and possessing high rebound and comfort.

[0004] The above-mentioned patent has the following defects in use:

[0005] The sole achieves high rebound performance through mechanical structures such as slide bars, sleeves, and springs. However, with the increase of mechanical structures such as slide bars, sleeves, and springs, the weight of the sole also increases, making it difficult to achieve the ultra-light effect and lightweight design. Therefore, this utility model proposes a high-rebound ultra-light sole. Utility Model Content

[0006] This invention provides a high-resilience, ultralight shoe sole. By incorporating small-pore aerogel in the forefoot area, its elastic structure allows for rapid shape recovery, providing greater rebound force when the foot exerts force. Meanwhile, large-pore aerogel in the heel area absorbs and disperses external impact energy through its porous structure, achieving excellent shock absorption and improving comfort. The large-pore aerogel also exhibits higher rigidity, providing better heel support. Furthermore, the TPU sealing bladder, combined with cushioning fluid, not only absorbs impact but also converts some energy into rebound force, enhancing the sole's rebound performance. Compared to mechanical structure designs, this design is significantly lighter, achieving an ultralight effect and thus solving the problems in the prior art.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model discloses a high-resilience ultralight shoe sole, comprising a TPU base, the interior of which is filled with a composite aerogel, and a TPU sealing bladder is embedded inside the composite aerogel. The interior of the TPU sealing bladder is filled with a buffer fluid, and the buffer fluid is initially in a soft state. Multiple first anti-slip blocks are fixedly connected to the bottom end of the TPU base, and multiple pairs of second anti-slip blocks are fixedly connected to the bottom end of the TPU base, with each pair of second anti-slip blocks located on both sides of the first anti-slip blocks.

[0009] Furthermore, the composite aerogel is composed of small-pore aerogel and large-pore aerogel. The small-pore aerogel is located in the forefoot area of ​​the TPU base, and the large-pore aerogel is located in the rearfoot area of ​​the TPU base. The surface of the composite aerogel is provided with a hydrophobic layer.

[0010] Furthermore, the TPU sealing capsule is composed of multiple Y-shaped splices, and the buffer fluid is a D3O non-Newtonian fluid.

[0011] Furthermore, multiple reinforcing ribs are fixedly connected between the inner wall of the TPU base and the top of the composite aerogel.

[0012] Furthermore, wear-resistant rubber strips are fixedly connected to the outer wall of the TPU base near the forefoot area and the heel area, respectively.

[0013] Furthermore, the first anti-slip block is V-shaped, and the second anti-slip block is rectangular. Both the bottom ends of the first and second anti-slip blocks are provided with hexagonal anti-slip patterns.

[0014] The present invention has the following advantages over the prior art:

[0015] 1. This technical solution uses a composite aerogel. Small-pore aerogel is placed in the forefoot area, which can quickly recover its shape due to its elastic structure, providing higher rebound force when the foot exerts force. Large-pore aerogel is placed in the heel area. Its pore structure can absorb and disperse external impact energy, achieving good shock absorption and improving comfort. At the same time, the pore structure of the large-pore aerogel has higher rigidity, which can provide better support for the heel.

[0016] 2. This technical solution, through the design of a TPU sealing bladder and buffer fluid, can not only absorb impact but also convert some of the energy into rebound force, enhancing the rebound performance of the sole. Compared with mechanical structure design, it is lighter, thus achieving an ultra-light effect.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] In the description of this utility model, it should be understood that the terms "relative", "one end", "inner", "lateral", "end", "both ends", "both sides", "front", "one end face", "the other end face", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Specific implementation examples:

[0028] Please see Figures 1-4 As shown, the present invention discloses a high-resilience ultralight shoe sole, comprising a TPU base 1, wherein the interior of the TPU base 1 is filled with a composite aerogel 2, and a TPU sealing bladder 3 is embedded inside the composite aerogel 2. The interior of the TPU sealing bladder 3 is filled with a buffer fluid 4, and the buffer fluid 4 is initially in a soft state. A plurality of first anti-slip blocks 7 are fixedly connected to the bottom end of the TPU base 1, and a plurality of pairs of second anti-slip blocks 8 are fixedly connected to the bottom end of the TPU base 1, wherein a pair of second anti-slip blocks 8 are respectively located on both sides of the first anti-slip blocks 7.

[0029] In the specific implementation process, the TPU base 1 is a high-performance thermoplastic elastomer. The porous structure of the TPU base 1 can disperse and absorb the impact of the force on the sole, and at the same time quickly restore its shape, thereby significantly improving the elasticity of the sole. The composite aerogel body 2 is mainly made of aerogel material, which has an extremely low density and is about 80% air inside, so it is very lightweight and can effectively reduce the weight of the sole. The porous structure of the aerogel can effectively absorb impact energy and has good elastic recovery, making it not easy to deform. The buffer fluid 4 inside the TPU sealing bladder 3 is D3O fluid, which can absorb and disperse impact force. When the foot lands, the sole will be impacted by the ground. The D3O fluid hardens instantly, absorbing some of the impact energy and protecting the foot joints from damage. At the same time, it can also convert some energy into rebound force, enhancing the rebound performance of the sole. Compared with the mechanical structure design, it is lighter, thus achieving an ultra-light effect. The first anti-slip block 7 and the second anti-slip block 8 can enhance the anti-slip performance of the sole and prevent slipping.

[0030] The composite aerogel 2 is composed of a small-pore aerogel 201 and a large-pore aerogel 202. The small-pore aerogel 201 is located in the front palm area of ​​the TPU base 1, and the large-pore aerogel 202 is located in the rear palm area of ​​the TPU base 1. A hydrophobic layer is provided on the surface of the composite aerogel 2.

[0031] A small-pore aerogel body 201 is set in the forefoot area. Its elastic structure can quickly restore its shape and provide higher rebound force when the foot exerts force. A large-pore aerogel body 202 is set in the heel area. Its pore structure can absorb and disperse external impact energy, achieve good shock absorption effect, and improve comfort. At the same time, the pore structure of the large-pore aerogel body 202 has higher rigidity and can provide better support for the heel. The surface of the composite aerogel body 2 is covered with a polydimethylsiloxane hydrophobic layer, which can prevent liquid penetration.

[0032] The TPU sealing bladder 3 is composed of multiple Y-shaped splices, and the buffer fluid 4 is a D3O non-Newtonian fluid.

[0033] The TPU sealing bladder 3 is composed of multiple Y-shaped splices, which can distribute the pressure to multiple support points when under pressure, reduce local stress concentration, and improve the durability of the TPU sealing bladder 3 under high pressure. In addition, D3O fluid is a non-Newtonian fluid, which can not only absorb impact, but also convert some energy into rebound force, enhancing the rebound performance of the sole.

[0034] Among them, multiple reinforcing ribs 5 are fixedly connected between the inner wall of the TPU base 1 and the top of the composite aerogel body 2.

[0035] The reinforcing ribs 5 made of TPU material can enhance the elastic deformation strength at the edges of the TPU base 1 and the composite aerogel 2.

[0036] Among them, wear-resistant rubber strips 6 are fixedly connected to the outer wall of the TPU base 1 near the forefoot area and the heel area respectively.

[0037] By setting abrasion-resistant rubber strips 6 on the outer wall of the TPU base 1 near the forefoot and heel areas, daily friction can be resisted, extending the life of the sole.

[0038] The first anti-slip block 7 is V-shaped, and the second anti-slip block 8 is rectangular. Both the bottom of the first anti-slip block 7 and the second anti-slip block 8 are provided with hexagonal anti-slip textures.

[0039] The first anti-slip block 7, with its V-shaped design, increases friction due to the raised sides, making the sole of the shoe more stable in contact with the ground. Furthermore, the hexagonal anti-slip pattern, due to its polygonal structure, increases the contact area, thereby enhancing friction.

[0040] The circuits, electronic components, and chip modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.

[0041] All standard parts used in the application documents can be purchased from the market. All components in this application document can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The electrical components mentioned in this document are all electrically connected to the external main controller and power supply, and the main controller is a conventional known device that can play a control role.

[0042] The working principle of this utility model is as follows:

[0043] In use, the TPU base 1 can disperse and absorb the impact of the shoe sole, while quickly restoring its shape and improving the elasticity of the sole. A small-pore aerogel body 201 is provided in the forefoot area, whose elastic structure allows it to quickly restore its shape and provide higher rebound force when the foot exerts force. A large-pore aerogel body 202 is provided in the heel area; its porous structure can absorb and disperse external impact energy, achieving good shock absorption and improving comfort. The porous structure of the large-pore aerogel body 202 also has higher rigidity, providing better support for the heel. Furthermore, the buffer fluid 4 inside the TPU sealing bladder 3 can absorb and disperse impact force. When the foot lands, the sole is impacted by the ground; the buffer fluid 4 hardens instantly, absorbing some of the impact energy and protecting the foot joints from damage. It can also convert some energy into rebound force, enhancing the rebound performance of the sole.
