[0002] With the promotion of national fitness, more and more people enjoy walking, running, and other sports. Consequently, their demands for athletic shoes are becoming increasingly specific, leading to a surge in the popularity of air-cushioned shoes due to the cushioning and shock absorption provided by air bladders. Currently, the structure of air-cushioned shoe soles on the market varies widely, ranging from pure air bladder cushioning to those with built-in support air bladders. However, it's difficult to achieve a perfectly flat air bladder surface or the necessary support surface for the foot when inflating the air bladder chamber, which can negatively impact foot comfort and the sole's cushioning performance.

[0023] The present invention will be further described in detail below with reference to specific embodiments.

[0024] like Figure 1-6 As shown, a shoe sole structure includes an upper shell 1 and a lower shell 2. The upper shell 1 and lower shell 2 are joined and sealed to form a gas-fillable chamber 3. A lattice 4 is provided within the chamber 3. The lattice 4 includes several upper end faces 411 that abut against the upper shell 1. An adhesive layer 5 connects the lattice 4 to the upper shell 1 between each upper end face 411 and the inner surface of the upper shell 1. The inner surface of the upper shell 1 is bonded to several upper end faces 411 of the lattice 4. When the chamber 3 is inflated to form an air cushion, the upper shell 1 will not bulge, thus reducing the pressure on the lattice 4, minimizing deformation and collapse, and improving the user's comfort while wearing the shoe.

[0025] Furthermore, the lattice 4 includes several lower end faces 421 that abut against the lower shell 2. By contacting multiple surfaces of the upper shell 1 and the lower shell 2, the lattice 4 achieves rapid and uniform dispersion of force when subjected to stress, reducing the deformation of the lattice-cushioned shoe sole and improving cushioning performance and durability.

[0026] In one embodiment of this utility model, the upper end face 411 and the lower end face 421 are staggered.

[0027] In another embodiment of this utility model, the upper end face 411 and the lower end face 421 are arranged opposite to each other.

[0028] The upper end face 411 and the lower end face 421 can be circular, elliptical, rectangular or polygonal, or enclosed by straight lines and arcs, respectively.

[0029] In a further specific embodiment, the lattice 4 includes multiple outer buffer units 41 and multiple inner buffer units 42. The upper end face 411 is disposed on the outer buffer unit 41, and the lower end face 421 is disposed on the inner buffer unit 42. Each outer buffer unit 41 is connected to at least three inner buffer units 42, and each inner buffer unit 42 is connected to at least three outer buffer units 41. The outer buffer units 41 and the inner buffer units 42 form a buffer space, and the whole is connected to form a mesh lattice structure.

[0030] In order to improve the compressive strength between the outer buffer unit 41 and the inner buffer unit 42, a connecting part 43 is provided between the outer buffer unit 41 and the inner buffer unit 42. Each connecting part 43 is circumferentially connected to the adjacent outer buffer unit 41 and the adjacent inner buffer unit 42. Multiple connecting parts 43 form an intermediate layer in the same direction as the upper shell 1 and the lower shell 2, which facilitates the uniform distribution of force and reduces the deformation of the lattice 4 under force.

[0031] In a preferred embodiment of this utility model, a first connecting arm 44 is provided between adjacent outer buffer units 41 to increase the force linkage between the outer buffer units 41. The force on each upper end surface 411 can be evenly distributed to the adjacent upper end surface 411. Multiple upper end surfaces 411 restrict each other and improve the force strength of the lattice 4.

[0032] Furthermore, the outer buffer unit 41 is provided with outer support legs 412 connecting adjacent connection portions 43, and the inner buffer unit 42 is provided with inner support legs 422 connecting adjacent connection portions 43, further improving the compressive strength of the outer buffer unit 41 and the inner buffer unit 42. The outer support legs 412 and the inner support legs 422 are preferably outwardly flared arcs, which can better distribute the force from the lateral and longitudinal directions. Each connection portion 43 collects the force from adjacent outer buffer units 41 and inner buffer units 42 and distributes it in multiple directions, further improving the overall buffering strength of the lattice 4.

[0033] When the outer buffer unit 41 and the inner buffer unit 42 are staggered, that is, the upper end face 411 and the lower end face 421 are staggered, and the first connecting arm 44 extends downward to connect the inner buffer unit 42 between adjacent outer buffer units 41, the lattice 4 can quickly disperse the force in both the lateral and longitudinal directions when subjected to force, thus achieving rapid buffering during the movement process. In a specific embodiment of this example, each connecting part 43 is staggered to connect adjacent outer buffer units 41 and adjacent inner buffer units 42. The force on each outer buffer unit 41 and inner buffer unit 42 can be evenly distributed to the adjacent force-bearing surface and evenly transmitted to the connecting part 43, forming progressive support and reducing impact. Further, the outer support leg 412 and the inner support leg 422 are staggered to connect the corresponding connecting part 43. Preferably, the connecting part 43 is flat and frustum-shaped, and multiple outer support legs 412 and inner support legs 422 are staggered along the circumference of the connecting part 43, making the force on the connecting part 43 more uniform. In a preferred embodiment of this embodiment, a third connecting arm 46 is provided between adjacent connecting parts 43. The third connecting arm 46 and the first connecting arm 44 form a cross skeleton of the inner buffer unit 42, thereby improving the overall strength of the intermediate layer and the strength of the inner buffer unit 42.

[0034] When the outer buffer unit 41 and the inner buffer unit 42 are arranged opposite each other, that is, the upper end face 411 and the lower end face 421 are arranged opposite each other, a second connecting arm 45 is provided between adjacent inner buffer units 42. The first connecting arm 44 has an end face flush with the adjacent upper end face 411, and the second connecting arm 45 has an end face flush with the adjacent lower end face 421. When the outer buffer unit 41 and the inner buffer unit 42 are subjected to force, the first connecting arm 44 and the second connecting arm 45 reduce the force transmitted from the upper end face 411 to the lower end face 421, thereby reducing damage to the lattice 4. In this embodiment, the outer buffer unit 41 and the inner buffer unit 42 have the same structure, and the upper and lower layers of the lattice 4 are symmetrically arranged.

[0035] In this embodiment, preferably, each outer buffer unit 41 is circumferentially connected to the corresponding inner buffer unit 42 by a connecting portion 43, and each connecting portion 43 evenly connects the surrounding adjacent outer buffer units 41 and inner buffer units 42. The outer support legs 412 of the outer buffer unit 41 and the inner support legs 422 of the corresponding inner buffer unit 42 can be directly connected to each other, or they can be connected to the connecting portions 43 respectively to dock; the outer support legs 412 of the outer buffer unit 41 and the inner support legs 422 of the adjacent inner buffer unit 42 can be staggered to dock, or they can be connected separately through the connecting portions 43. Preferably, the outer support legs 412 and the inner support legs 422 are connected to the connecting portions 43 in an outwardly expanding manner, forming two pairs of parallel connecting legs between the outer buffer unit 41 and the inner buffer unit 42, which are not easily broken under stress. Multiple connecting portions 43 form an intermediate layer in the same direction as the lower shell 2 and the upper shell 1, making the lattice 4 a three-layered elastomer.

[0036] The connecting portion 43 connects the surrounding adjacent outer buffer units 41 and inner buffer units 42, so that the multiple upper end faces 411 and multiple lower end faces 421 respectively form multiple small starburst structures. Preferably, each connecting portion 43 is surrounded by four to six outer buffer units 41 and four to six inner buffer units 42, which can form a four-pointed starburst structure or a hexagonal starburst structure. The number of connecting portions 43 affects the buffering hardness of the lattice 4 to a certain extent.

[0037] In a preferred embodiment of this invention, the lattice 4 is a one-piece molded structure, the upper shell 1 and the lower shell 2 are airtightly connected, the chamber 3 is filled with gas, and the upper end face 411 of the lattice 4 is fixed to...

[0038] Upper shell 1 maintains the flatness and cushioning stability of the entire inflatable insole; lattice 4

[0039] The lower end face 421 can also be fixed to the lower housing 2 by an adhesive layer.
