Description

Technical Field

[0001] This utility model relates to the field of footwear manufacturing technology, specifically a shoe sole with low noise from friction on water. Background Technology

[0002] Shoes are necessities for daily life, sports and professional work, especially in rainy days. The performance of the soles directly affects the user's experience. However, among the performance indicators of soles, "slip resistance" and "quietness" are two crucial but inherently contradictory core attributes.

[0003] Traditional design concepts treat anti-slip and noise reduction as a linear trade-off, failing to fundamentally solve the problem of their synergy. Anti-slip requires "interlocking" and "drainage," while noise reduction requires "buffering" and "adsorption." A single material and a simple macroscopic structure cannot simultaneously meet these physical requirements.

[0004] In view of this, we propose a shoe sole with low friction noise on water. Summary of the Invention

[0005] The purpose of this invention is to provide a shoe sole with low noise from friction on water, in order to solve the problems mentioned in the background art.

[0006] A shoe sole with low water friction noise is characterized by comprising a sole made of soft foam sound-absorbing material, the sole being divided into a forefoot portion and a heel portion, a recessed portion being provided between the forefoot portion and the heel portion, a plurality of drainage grooves being provided on the ground contact surface of the forefoot portion and the heel portion, an air bladder being embedded inside the heel portion, and the outer edge of the sole contact surface with the ground being rounded.

[0007] Preferably, the forefoot portion has a first airflow channel with vertical stripes at the front end, a first sound-dampening block in the middle of the forefoot portion, and the surface of the first sound-dampening block is covered with a first anti-slip layer made of high-damping material. Second sound-dampening blocks are provided on both sides of the forefoot portion, and the surface of the forefoot portion has a second airflow channel with a W-shaped pattern.

[0008] Preferably, a third sound-dampening block is provided on both sides of the heel portion, a third flow channel with a horizontal wave pattern is provided at the rear end of the heel portion, and a fourth flow channel with a V-shaped pattern is provided on the surface of the heel portion.

[0009] Preferably, a fourth silencing block is provided in the middle of the recessed portion, and the surface of the fourth silencing block is covered with a second anti-slip layer made of a high-damping material.

[0010] Beneficial effects

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: the sole surface of this shoe is designed in sections, and an airbag is embedded in the heel part where the human foot bears the most weight, which can better cushion the force when the foot lands, thereby reducing noise.

[0012] The sole is made of soft, sound-absorbing material using a foaming process. A high-damping soft contact layer is applied to the core support area. The combination of these two materials effectively absorbs and dissipates vibration energy generated when the foot hits the ground and during friction, eliminating noise at its source. The rounded corners of the outer edge of the sole's contact surface with the ground prevent scratching noises.

[0013] Multiple drainage channels on the sole surface and a high-damping soft contact layer material effectively dissipate residual water film and enhance adsorption to the ground through intermolecular forces (van der Waals forces); the multi-directional drainage pattern can quickly dissipate a large amount of accumulated water. The two work together to provide a friction coefficient far exceeding that of conventional soles. Attached Figure Description

[0020] Please see Figure 1-2 This utility model provides a technical solution:

[0021] A shoe sole with low water friction noise includes a sole 1 made of soft foam sound-absorbing material. The sole 1 is divided into a forefoot portion 11 and a heel portion 12. A recessed portion 13 is provided between the forefoot portion 11 and the heel portion 12. Several guide grooves are provided on the ground contact surfaces of the forefoot portion 11 and the heel portion 12. An airbag 204 is embedded inside the heel portion 12. The outer edge of the contact surface of the sole 1 with the ground is rounded. A first guide groove 101 with vertical stripes is provided at the front end of the forefoot portion 11. A first sound-absorbing block 102 is provided in the middle of the forefoot portion 11. 02 The surface is covered with a first anti-slip layer 103 made of high damping material. The forefoot portion 11 is provided with second sound-dampening blocks 104 on both sides. The surface of the forefoot portion 11 is provided with a second guide groove 105 with a W-shaped pattern. The rearfoot portion 12 is provided with third sound-dampening blocks 201 on both sides. The rear end of the rearfoot portion 12 is provided with a third guide groove 202 with a horizontal wave pattern. The surface of the rearfoot portion 12 is provided with a fourth guide groove 203 with a V-shaped pattern. The recessed portion 13 is provided with a fourth sound-dampening block 301 in the middle. The surface of the fourth sound-dampening block 301 is covered with a second anti-slip layer 302 made of high damping material.

[0022] It should be explained that the sound-silencing block is made of a soft sound-silencing material produced by a foaming process; the anti-slip layer is a high-damping soft material layer covering the surface of the sound-silencing block.

[0023] Understandably, when a person walks, the heel strikes the ground first and experiences the most concentrated stress. The soft, sound-absorbing material and the cushioning support of the airbag 204 eliminate noise. Simultaneously, the design of the third and fourth drainage channels 202 on the surface allows different textures to quickly break through the water film and drain accumulated water, creating a dry contact surface for the sound-absorbing material to maximize its adhesion to the ground through intermolecular forces (van der Waals forces). A second anti-slip layer 302 is provided in the recessed area 13 of the sole 1, providing support and protection for the foot. Slip function; when a person walks, the forefoot exerts force and is the main part that generates friction noise. Therefore, a first anti-slip layer 103 is provided in the middle of the forefoot part 11. Since the first anti-slip layer 103 is provided on the surface of the first silencing block 102, the friction and impact generated by the first anti-slip layer 103 in contact with the ground can be absorbed by the first silencing block 102. The sides of the forefoot part 11 are composed of second silencing blocks 104, and the edges are rounded to avoid abnormal noise caused by scratching.

[0024] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
