DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the implementation modes and the accompanying drawings. Here, the illustrative implementation modes and descriptions of the present application are used to explain the present application, but are not intended to limit the present application.

[0027] refer to Figures 1 to 7 ,like Figure 1 As shown, this embodiment provides a shock-absorbing shoe, comprising: a sole 1 and an upper 2 connected to the sole 1, the heel portion of the sole 1 is provided with a first elastic component 3 and a second elastic component 4, wherein the first elastic component 3 is installed in the center of the heel portion, and the second elastic component 4 includes a plurality of elastic members 41 distributed around the first elastic component 3.

[0028] Specifically, through local design, a first elastic component 3 and a second elastic component 4 are arranged at the heel portion of the sole 1, and a third elastic component is arranged at the toe portion of the sole 1, so that different parts of the sole 1 have different shock-absorbing effects, so that the heel and the toe are effectively cushioned respectively, thereby improving the comfort of use, and through the coordinated use of the first elastic component 3 and the second elastic component 4, the heel portion has better supporting performance, thereby improving the stability of use.

[0029] In one embodiment, please refer to Figure 2The sole 1 includes a lower sole 12 and an upper sole 11 tightly connected to the lower sole 12, the upper 2 is connected to the upper sole 11, an upper groove 16 is provided on the lower surface of the upper sole 11, and a lower groove 17 corresponding to the upper groove 16 is provided on the upper surface of the lower sole 12. The first elastic component 3 and the second elastic component 4 are both located in the installation cavity 13 formed by the upper groove 16 and the lower groove 17, making the sole 1 more compact and easier to use.

[0030] In one embodiment, please refer to Figure 3 and Figure 4 A plurality of sleeves 112 are provided near the inner wall of the upper groove 16, and a guide rod 122 is provided in the lower groove 17 and can slide relative to the sleeve 112. The elastic member 41 is sleeved on the guide rod 122, and one end of the elastic member 41 is in contact with the sleeve 112, and the other end is in contact with the bottom wall of the lower groove 17. The sleeve 112 and the guide rod 122 both play a guiding role, so that the elastic member 41 can be elastically deformed in a specific direction, avoiding the elastic member 41 from deflecting, thereby improving the stability during use.

[0031] Optionally, the elastic member 41 is a cylindrical helical compression spring or a pagoda-shaped spring.

[0032] Preferably, the elastic member 41 is a pagoda-shaped spring. In the same installation space, a pagoda-shaped spring of the same volume can withstand greater pressure than an ordinary compression spring, and correspondingly can store more energy, and can withstand greater pressure under the same deformation amount. The structure of the pagoda-shaped spring enables it to withstand more stress changes without fatigue damage, and thus can have a longer life and higher reliability.

[0033] In one embodiment, please refer to Figure 6 The first elastic component 3 includes a first supporting layer 31, a polyurethane layer 32 and a second supporting layer 33 arranged in sequence from top to bottom. The first supporting layer 31 is a latex layer to improve the comfort of use. Polyurethane has good wear resistance, chemical resistance, high strength, good waterproof performance, elasticity and shock absorption.

[0034] For details, please refer to Figure 4 The upper bottom 11 and the lower bottom 12 are provided with positioning grooves 14 on the surfaces where they are in contact, and the elastic member 41 and the first elastic component 3 are both located in the positioning grooves 14. Please refer to Figure 6 The overall structure of the first elastic component 3 is a prism, a cylinder or a truncated cone structure. The first elastic component 3 is connected to the positioning groove 14 located on the lower bottom 12. The top surface of the first elastic component 3 is in contact with the upper bottom 11, which plays a role in buffering and shock absorption.

[0035] In one embodiment, please refer to Figure 5 and Figure 7 The second supporting layer 33 includes a supporting plate 331 and a plurality of “G”-shaped spring sheets 332 spaced apart on the supporting plate 331. The side of the supporting plate 331 away from the spring sheets 332 is connected to the polyurethane layer 32, and the lower end of the spring sheets 332 abuts against the bottom wall of the lower groove 17.

[0036] In one embodiment, please refer to Figure 7 The outwardly extending end 3321 of the spring sheet 332 is provided with a pressing block 333 which can contact with the inwardly extending end 3322 of the spring sheet 332. The inwardly extending end 3322 is elastically deformed by the pressing block 333, thereby playing a role of buffering and shock absorption.

[0037] Specifically, the spring piece 332 is elastic. When people are walking and are squeezed, the two ends of the spring piece 332 are squeezed against each other, which plays a role of buffering and shock absorption. As the squeezing force increases, the pressing block 333 moves downward and presses the inner extending end 3322. The inner extending end 3322 is squeezed and elastically deforms, which plays a role of buffering and shock absorption. Therefore, the first elastic component 3 has a good buffering effect, and the spring piece 332 can be connected to the support plate 331 by the screw 334.

[0038] It should be noted that the spring piece 332 and the pressing block 333 can be formed by integral processing, such as by bending processing, which reduces the processing difficulty and improves the processing efficiency.

[0039] In one embodiment, please refer to Figure 4 The third elastic component includes a funnel-shaped elastic protrusion arranged on the lower surface of the upper bottom 11, and a concave cavity corresponding to the elastic protrusion is opened on the upper surface of the lower bottom 12. The elastic protrusion is in conflict with the concave cavity. The elastic protrusion is elastic. Through the cooperation between the elastic protrusion and the concave cavity, the toe of the shoe is cushioned to protect the user's toes.

[0040] In one embodiment, please refer to Figure 4 and Figure 5 The sizes of the multiple elastic members 41 gradually decrease from the heel of the sole 1 to the toe, and the heel bears the greatest force. By setting elastic members 41 of different sizes, different positions of the heel have different elastic forces, which better adapts to the user's walking state and improves the comfort of use.

[0041] In one embodiment, please refer to Figure 1Upper bottom positioning blocks 111 are provided on both sides of the upper bottom 11, lower bottom positioning blocks 121 are provided on both sides of the lower bottom 12 to fit with the upper bottom positioning blocks 111 to achieve positioning in the front-to-back direction, the lower end of the upper bottom positioning block 111 has a lower extension edge 1111 that fits with the outer side surface of the lower bottom 12, and the upper end of the lower bottom positioning block 121 has an upper extension edge 1211 that fits with the outer side surface of the upper bottom 11.

[0042] Specifically, the upper bottom positioning block 111 and the lower bottom positioning block 121 are both rectangular blocks or trapezoidal blocks. The upper bottom 11 and the lower bottom 12 are positioned in the front-to-back direction through the cooperation of the upper bottom positioning block 111 and the lower bottom positioning block 121. The upper bottom 11 and the lower bottom 12 are positioned in the left-to-right direction through the lower extension edge 1111 and the upper extension edge 1211, thereby improving the installation accuracy of the upper bottom 11 and the lower bottom 12.

[0043] The shock absorption device has excellent shock absorption performance and good stability, ensuring that the walking process is more stable and reliable, more comfortable to use, and meets the needs of more people.
