This enables the elastic column to maintain good elastic performance during long-term use, prevents the elastic column from losing elasticity, ensures the long-term elasticity of the shoe sole, and the high wear resistance and tear resistance of the TPU material prevent the elastic column from being damaged during frequent pressing and deformation, thereby improving the stability and reliability of the elastic structure, and improving the overall quality and service life of the shoe, thereby providing a better product experience for consumers.

[0009] The technical scheme has the beneficial effects that when a wearer walks or moves to exert pressure on the shoe sole, the elastic cavities in the forefoot region and the heel region of the shoe sole are extruded, at this time, slight deformation of the shoe sole causes the elastic cavities to slightly deform and drive the second auxiliary blocks to move towards the elastic columns, that is, the first auxiliary block and the second auxiliary block are both relatively moved towards the corresponding elastic column, the first inclined surface of the first auxiliary block and the second inclined surface of the second auxiliary block are in contact with and interact with the outer wall of the elastic column, guiding the elastic column to produce greater deformation in a specific direction, so that the elastic column stores more elastic potential energy, with the continuous increase of the pressure, the degree of deformation of the elastic column continuously increases, and the first auxiliary block and the second auxiliary block will also bear certain pressure, and the interaction force between them and the elastic column is further enhanced, promoting the elastic column to store more energy, when the pressure disappears, the elastic column storing a large amount of elastic potential energy begins to restore to the original state, and in the restoring process, the elastic column will push the first auxiliary block and the second auxiliary block in the opposite direction. Since the first auxiliary block and the second auxiliary block are connected with the bottom wall and the top wall of the elastic cavity respectively, they will play a certain supporting and assisting role in the restoration of the elastic column, so that the elastic column can rebound more quickly and more powerfully. At the same time, the force generated by the rebound of the elastic column is transmitted to the foot through the shoe sole, providing an upward reaction force for the wearer, helping the foot to complete the lifting action, realizing the efficient rebound process of the shoe sole, and providing a good walking experience for the wearer; in the above technology, when the shoe sole is pressed, the first inclined surface of the first auxiliary block and the second inclined surface of the second auxiliary block are in abutting engagement with the outer wall of the elastic column, which can guide and limit the deformation direction of the elastic column, so that the elastic column produces greater deformation in a specific direction, thereby effectively improving the deformation strength of the elastic structure and further enhancing the rebounding property of the shoe sole; through the setting of the first auxiliary block and the second auxiliary block, the pressure received by the shoe sole can be more evenly transmitted to the elastic column. The abutting engagement of the first inclined surface and the second inclined surface with the elastic column can disperse the pressure to different parts of the elastic column, avoiding local stress concentration and improving the stress rationality and stability of the elastic column. In this way, not only the overall performance of the elastic structure is improved, but also the service life of the elastic column is prolonged, ensuring the long-term rebound effect of the shoe sole; the connection of the first auxiliary block and the second auxiliary block with the wall of the elastic cavity and the cooperation with the elastic column can effectively inhibit the possible excessive deformation or distortion of the shoe sole when it is pressed, provide more stable support for the wearer, reduce the risk of foot fatigue and injury caused by unstable shoe sole, and improve the safety and comfort of wearing; and the first auxiliary block on the front side and the second auxiliary block on the rear side of each elastic column are oppositely arranged, forming a whole structure that works cooperatively, in the process of pressure receiving and rebounding of the shoe sole, the first auxiliary block, the second auxiliary block and the elastic column can be interconnected, and store and release elastic potential energy together, and the cooperative working mechanism makes the performance of the elastic structure fully exerted, further improving the rebound performance and buffering effect of the shoe sole, and providing a more comfortable walking experience for the wearer.

[0010] The utility model further sets up: first auxiliary block and second auxiliary block all are made of TPU material.

[0011] The above technical scheme has the advantages that: TPU material has excellent elastic performance, the first auxiliary block and the second auxiliary block are made of the material, which can realize good matching and cooperation with the elastic column made of TPU material in elasticity, and they can synchronously elastically deform when the sole is pressed, more effectively assisting the elastic column to store elastic potential energy, and after the pressure is released, they can quickly rebound together with the elastic column, further enhancing the overall resilience and buffering performance of the sole, providing a more comfortable foot feeling experience for the wearer; TPU material has excellent wear resistance, which makes the first auxiliary block and the second auxiliary block not prone to wear and damage even if they frequently abut and rub against the elastic column during long-term use, compared with other materials, they can better maintain their structural integrity and performance stability, thereby prolonging the service life of the entire elastic structure and the sole, reducing problems such as decreased sole resilience caused by component wear, and improving the durability and practicality of the shoe.

[0012] The utility model further sets up: the elastic column is penetrated by deformation hole along its width direction, the deformation hole diameter cross section is oval-shaped setting, the loading piece includes a plurality of metal elastic sheets, the metal elastic sheet diameter cross section is arc-shaped setting and metal elastic sheet includes two end portions and protuberance portion, the protuberance portion is towards the sole end face setting, a plurality of metal elastic sheets and a plurality of deformation holes are one-to-one corresponding and the protuberance portion of each metal elastic sheet all is in respective corresponding deformation hole, the protuberance portion end wall of metal elastic sheet and deformation hole inner wall abutment cooperation setting.

[0013] The technical scheme has the beneficial effects that when a wearer exerts pressure on the shoe sole, the elastic cavities of the forefoot region and the heel region of the shoe sole are extruded, and the elastic column starts to deform. Since the elastic column is provided with the deformation hole and contains the metal spring inside, when the elastic column deforms, the protruding part of the metal spring is also extruded. The arc-shaped structure of the metal spring causes the protruding part to bend and deform to the two sides of the deformation hole when the metal spring is extruded, which further increases the deformation degree of the elastic column, thereby storing more elastic potential energy. Compared with the simple elastic column structure, the combination of the elastic column and the metal spring greatly increases the degree and range of elastic deformation, and more elastic potential energy can be stored, thereby significantly improving the resilience of the shoe sole, providing stronger support and rebound force for the wearer, and improving the comfort and efficiency during walking or exercising. The protruding part of the metal spring is in abutting engagement with the inner wall of the deformation hole. When the shoe sole is extruded, the pressure is evenly dispersed to each part of the elastic column through the metal spring, avoiding local stress concentration. This pressure dispersion mechanism not only helps to protect the elastic column and the metal spring, prolonging their service life, but also makes the shoe sole produce more uniform cushioning effect when extruded, effectively reducing the impact force of the ground on the feet, providing more comfortable and stable cushioning protection for the feet. Meanwhile, since the metal spring has good elasticity and rapid recovery performance, the metal spring can quickly deform and recover to its original state during the extrusion and pressure release of the shoe sole.

[0014] The utility model further sets up: metal spring both ends part all are connected with the shoe sole setting.

[0015] The technical scheme has the beneficial effects that the metal spring is connected with the shoe sole at both ends, which can stably fix the metal spring in the elastic structure of the shoe sole. Meanwhile, the metal spring is connected with the shoe sole at both ends, so that the force received by the shoe sole can be directly and efficiently transmitted to the metal spring. When the shoe sole is extruded, the pressure can be quickly transmitted to both ends of the metal spring through the shoe sole, and the protruding part of the metal spring deforms correspondingly in the deformation hole. The metal spring fully plays the role of increasing elastic deformation and storing elastic potential energy. During the rebound process, the elastic potential energy stored in the metal spring can be more smoothly transmitted back to the shoe sole through both ends, providing stronger rebound power for the shoe sole, and improving the response speed and effect of the resilience of the shoe sole.
