Description

Technical Field

[0001] This invention relates to air cushion structures; in particular, it relates to a three-dimensional curved air cushion module and a finished curved air cushion product. Background Technology

[0002] Existing air cushion structures are mostly manufactured using blow molding, but this process still faces many technical bottlenecks when creating hollow objects with high sidewalls or curved surfaces. For example, when manufacturing hollow structures with high sidewalls, it is difficult to control the sidewall thickness during material stretching, often resulting in uneven sidewall thickness in the finished product. This reduces the shock absorption effect and durability of the air cushion structure.

[0003] Furthermore, the curved air cushion design also suffers from stress concentration at the connection between the curved surface and the sidewall, affecting the overall structural stability. Even with special mold design, traditional blow molding technology still struggles to overcome the technical challenges of uneven thickness distribution and poor material flowability faced by high sidewall extension or complex curved surface forming. This results in limitations in the structural design and performance of existing air cushion products, failing to meet the market's demand for high-performance, high-stability air cushion products. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a three-dimensional curved air cushion module and a finished curved air cushion product. The design of the three-dimensional curved air cushion module can effectively reduce the maximum height of the side wall placed in the mold and improve the yield of the finished curved air cushion product filled by the three-dimensional curved air cushion module.

[0005] To achieve the above objectives, the present invention provides a three-dimensional curved surface air cushion module, comprising a first air cushion portion and a second air cushion portion, wherein the second air cushion portion is pivotally connected to the first air cushion portion. The first air cushion portion has a first outer surface, a first arc surface, and a first connecting surface. The first outer surface has a first upper edge and a first lower edge at both ends. The first arc surface is connected to the first upper edge of the first outer surface, and the first connecting surface is connected to the first lower edge of the first outer surface. The second air cushion portion has a second outer surface, a second arc surface, and a second connecting surface. The second outer surface has a second upper edge and a second lower edge at both ends. The second arc surface corresponds to the outline and position of the first arc surface and is connected to the first upper edge of the first outer side surface. The second connecting surface is connected to the second lower edge of the second outer side surface. The second connecting surface is adjacent to the first connecting surface. The three-dimensional curved air cushion module defines a pivot line corresponding to the junction of the first connecting surface and the second connecting surface. The first air cushion part and the second air cushion part are pivotally opened by the pivot line, so that the first outer side surface and the second outer side surface are relatively inclined. There is a first height between the first upper edge and the first lower edge that is less than the wall height of the first outer side surface. There is a second height between the second upper edge and the second lower edge that is less than the wall height of the second outer side surface.

[0006] Another embodiment of the present invention provides a curved air cushion product, comprising a three-dimensional curved air cushion module. The three-dimensional curved air cushion module has a first air cushion portion and a second air cushion portion, the first air cushion portion and the second air cushion portion being pivotally connected, and the first air cushion portion and the second air cushion portion being respectively filled with fluid. The first air cushion portion has a first outer surface, a first arc surface and a first connecting surface, the first arc surface and the first connecting surface being connected at both ends of the first outer surface. The second air cushion portion has a second outer surface, a second arc surface and a second connecting surface, the second arc surface and the second connecting surface being connected at both ends of the first outer surface. The surface is connected to both ends of the second outer surface. The second arc surface corresponds to the outline and position of the first arc surface. The second connecting surface is adjacent to the first connecting surface. The three-dimensional curved air cushion module defines a pivot line corresponding to the connection between the first connecting surface and the second connecting surface. The first air cushion part and the second air cushion part are arranged side by side with the pivot line and fixed by a fixing means, so that the first arc surface of the first air cushion part and the second arc surface of the second air cushion part face each other, and the first arc surface and the second arc surface are adjacent to each other to form a continuous curved surface.

[0007] Another embodiment of the present invention provides a finished curved air cushion product, comprising a three-dimensional curved air cushion module. The three-dimensional curved air cushion module has a first air cushion portion and a second air cushion portion, the first air cushion portion and the second air cushion portion being filled with fluid respectively. The first air cushion portion has a first arc surface; the second air cushion portion has a second arc surface, the second arc surface corresponding to the contour of the first arc surface. The three-dimensional curved air cushion module is connected side by side to the first air cushion portion and the second air cushion portion by a fixing means, such that the first arc surface of the first air cushion portion and the second arc surface of the second air cushion portion face each other, and the first arc surface and the second arc surface are adjacent to each other to form a continuous curved surface.

[0008] The advantage of this invention is that the plurality of first air cushion portions and the plurality of second air cushion portions designed in the three-dimensional curved air cushion module can pivot along the pivot line, making the three-dimensional curved air cushion module more flexible in the filling process. When the three-dimensional curved air cushion module is placed in an air cushion molding mold for filling and molding, the three-dimensional curved air cushion module is pivoted along the pivot line to open the first air cushion portions and the second air cushion portions relative to each other, so that the first outer surface of each first air cushion portion and the second outer surface of each second air cushion portion are relatively inclined, effectively reducing the maximum height of each first air cushion portion and each second air cushion portion on the side wall of the air cushion molding mold. In this way, during the filling and molding process, the plurality of first air cushion portions and the plurality of second air cushion portions can stably control the thickness distribution at the junction of the first outer surface and the first arc surface and the junction of the second outer surface and the second arc surface, thereby improving the molding yield of the three-dimensional curved air cushion module.

[0009] Furthermore, the finished curved air cushion is formed by filling the three-dimensional curved air cushion modules, and the finished curved air cushion has a continuous curved surface, which enhances the elastic support of the foot blade and the inner side of the foot. The three-dimensional curved air cushion modules can be fixed side by side by adhesives or frames to improve the structural stability of the finished curved air cushion. In addition, the finished curved air cushion can also adjust the filling pressure of the first air cushion and the second air cushion according to the wearer's gait differences. For example, the finished curved air cushion can adjust the filling pressure of the first air cushion to be greater than the filling pressure of the second air cushion according to the foot pressure of the wearer with pronation, which helps to support the pressure of the wearer's pronation. Alternatively, the finished curved air cushion can also adjust the filling pressure of the second air cushion to be greater than the filling pressure of the first air cushion according to the wearer with inversion, which improves the wearer's walking comfort and safety.

[0130] To more clearly illustrate the present invention, preferred embodiments are described in detail below with reference to the accompanying drawings. Please refer to... Figure 1 , Figure 2 The three-dimensional curved air cushion module 100 provided in the first preferred embodiment of the present invention includes a plurality of first air cushion portions 10 and a plurality of second air cushion portions 20. The plurality of first air cushion portions 10 and the plurality of second air cushion portions 20 are pivotally connected. In this first embodiment, the plurality of first air cushion portions 10 and the plurality of second air cushion portions 20 are all three-dimensional hollow structures. The three-dimensional curved air cushion module 100 defines a pivot line L1 located at the pivot position between each of the first air cushion portions 10 and each of the second air cushion portions 20. The three-dimensional curved air cushion module 100 is a semi-finished product that has not yet been filled with fluid. The fluid can be gas or liquid.

[0131] The plurality of first air cushion portions 10 are connected side by side corresponding to the direction of the pivot line L1, such as Figures 2-4 As shown, each of the first air cushion portions 10 has a first inner side surface 11, a first outer side surface 12, a first arc surface 13, a first connecting surface 14, a first front side surface 15, and a first rear side surface 16. The first inner side surface 11 and the first outer side surface 12 are located opposite each other on both sides of the first air cushion portion 10. The first outer side surface 12 has a first upper edge 121 and a first lower edge 122 at both ends. The first arc surface 13 extends upward in an arc shape from the first inner side surface 11 toward the first outer side surface 12 and connects to the first upper edge 121. The first connecting surface 14 is flatly connected to the first lower edge 122 and the first inner side surface 11 of the first outer side surface 12 relative to the first arc surface 13. The first front side surface 15 and the first rear side surface 16 are connected to the first inner side surface 11, the first outer side surface 12, the first arc surface 13, and the first connecting surface 14 in the direction of the pivot line L1. The plurality of first air cushion portions 10 are connected coplanarly with the plurality of first connecting surfaces 14 and the plurality of first outer side surfaces 12.

[0132] The plurality of second air cushion portions 20 are connected side by side corresponding to the direction of the pivot line L1, and the structure of the plurality of second air cushion portions 20 is substantially similar to that of the plurality of first air cushion portions 10, such as... Figure 2 , Figure 3As shown, each of the second air cushion portions 20 has a second inner surface 21, a second outer surface 22, a second arc surface 23, a second connecting surface 24, a second front surface 25, and a second rear surface 26. The second inner surface 21 and the second outer surface 22 are located opposite each other on both sides of the second air cushion portion 20, and the first inner surface 11 and the second inner surface 21 face each other. The two ends of the second outer surface 22 have a second upper edge 221 and a second lower edge 222. The second arc surface 23, corresponding to the outline and position of the first arc surface 13, extends upward in an arc shape from the second inner surface 21 toward the second outer surface 22 and connects to the second upper edge 221. The second connecting surface 24 is directly connected to the second lower side edge 222 and the second inner side surface 21 of the second outer side surface 22 relative to the second arc surface 23, and the second connecting surface 24 is adjacent to the first connecting surface 14. The second front side surface 25 and the second rear side surface 26 are connected to the second inner side surface 21, the second outer side surface 22, the second arc surface 23 and the second connecting surface 24 in the direction of the pivot line L1, wherein the pivot line L1 corresponds to the junction of the first connecting surface 14 and the second connecting surface 24, and the plurality of second air cushion portions 20 are coplanarly connected to the plurality of second connecting surfaces 24 and the plurality of second outer side surfaces 23.

[0133] like Figure 2 As shown, in this first embodiment, the three-dimensional curved air cushion module 100 further includes a plurality of first axial connecting portions 30, a plurality of second axial connecting portions 40, and a transverse connecting portion 50.

[0134] The plurality of first axial connecting portions 30 are respectively disposed between every two adjacent first air cushion portions 10, such as Figure 2 As shown, there is a first gap 17 between each two adjacent first air cushion portions 10. Each first axial connecting portion 30 is disposed in each first gap 17 and is coupled to the first connecting surface 14, so that the two ends of each first axial connecting portion 30 connect the first front side 15 of one first air cushion portion 10 and the first rear side 16 of the adjacent first air cushion portion 10. There is a first clamping groove 18 between each two adjacent first air cushion portions 10. Each first clamping groove 18 passes through the first gap 17 from the first arc surface 13 toward the first connecting surface 14, and each first clamping groove 18 is disposed between the first front side 15 of one first air cushion portion 10 and the first rear side 16 of the adjacent first air cushion portion 10.

[0135] The plurality of second axial connecting portions 40 are respectively disposed between every two adjacent second air cushion portions 20, such as Figure 2As shown, similarly, there is a second gap 27 between each two adjacent second air cushion portions 20, and each second axial connecting portion 40 is disposed in each second gap 27 and coupled to the second connecting surface 24, so that the two ends of each second axial connecting portion 40 connect the second front side 25 of one second air cushion portion 20 and the second rear side 26 of the adjacent second air cushion portion 20. There is a second clamping groove 28 between each two adjacent second air cushion portions 20, and each second clamping groove 28 passes through the second gap 27 from the second arc surface 23 toward the second connecting surface 24, and each second clamping groove 28 is disposed between the second front side 25 of one second air cushion portion 20 and the second rear side 26 of the adjacent second air cushion portion 20.

[0136] like Figure 2 As shown, the transverse connecting part 50 is an elastic telescopic tube. The transverse connecting part 50 is disposed between the first inner side 11 of one of the first air cushion parts 10 and the second inner side 21 of one of the second air cushion parts 20, so that the plurality of first air cushion parts 10 and the plurality of second air cushion parts 20 are connected through the transverse connecting part 50.

[0137] However, in other embodiments, the structure and arrangement of the three-dimensional curved air cushion module 100 can be adjusted as needed. For example, each pair of adjacent first air cushion portions 10 can be directly fitted together to omit the first gap 17, and the first clamping groove 18 can also be omitted; each pair of adjacent second air cushion portions 20 can be directly fitted together to omit the second gap 27, and the second clamping groove 28 can also be omitted; the three-dimensional curved air cushion module 100 can omit the setting of the plurality of first axial connecting portions 30, the plurality of second axial connecting portions 40 and the transverse connecting portions 50, as long as each first air cushion portion 10 and each second air cushion portion 20 can be independently filled with fluid, and it is not limited that two adjacent first air cushion portions 10 and two adjacent second air cushion portions 20 are interconnected; the number of first air cushion portions 10 and the number of second air cushion portions 20 can each be at least one; the number of transverse connecting portions 50 can also be multiple to connect each first air cushion portion 10 and each second air cushion portion 20.

[0138] like Figures 2-5As shown, the three-dimensional curved air cushion module 100 defines a central axis L2 located between the first inner side surface 11 of each first air cushion part 10 and the second inner side surface 21 of each second air cushion part 20 and passing through the pivot line L1. Each first air cushion part 10 and each second air cushion part 20 pivots open along the pivot line L1, so that each first outer side surface 12 and each second outer side surface 22 are relatively inclined. At this time, there is a first included angle θ1 between the first inner side surface 11 and the central axis L2, and there is a second included angle θ2 between the second inner side surface 21 and the central axis L2. The first included angle θ1 and the second included angle θ2 are respectively between 10° and 45°, and the first clamping groove 18 on each first air cushion part 10 and the second clamping groove 28 on each second air cushion part 20 are respectively parallel to the central axis L2.

[0139] In addition, in this first embodiment, when the three-dimensional curved air cushion module 100 is pivotally opened by the pivot line L1, there is a first height H1 between the first upper side edge 121 and the first lower side edge 122. The first height H1 is less than the wall height D1 of the first outer side surface 12. There is a second height H2 between the second upper side edge 221 and the second lower side edge 222. The second height H2 is less than the wall height D2 of the second outer side surface 22. The first height H1 is the height between the first upper side edge 121 and the first lower side edge 122 when the first outer side surface 12 is tilted. The wall height D1 of the first outer side surface 12 is the height of the first upper side edge 121 and the first lower side edge 122 on the first outer side surface 12. The second height H2 is the height between the second upper side edge 221 and the second lower side edge 222 when the second outer side surface 22 is tilted. The wall height D2 of the second outer side surface 22 is the height of the second upper side edge 221 and the second lower side edge 222 on the second outer side surface 22.

[0140] To further explain, such as Figure 4As shown, this first embodiment uses a single first air cushion portion 10 and a single second air cushion portion 20 for illustration. The first arc surface 13 of the first air cushion portion 10 has a first valley bottom reference point 131, which is the center of the valley of the first arc surface 13. The first air cushion portion 10 defines a first reference line L3 tangent to the first valley bottom reference point 131 of the first arc surface 13. The first reference line L3 passes through the first outer surface 12 and is perpendicular to the central axis L2. The first upper edge 121 and the first lower edge 122 of the first outer surface 12 are located on both sides of the first reference line L3. The first air cushion portion 10 has a first upper edge spacing G11 between the first reference line L3 and the first upper edge 121, and a first lower edge spacing G12 between the first reference line L3 and the first lower edge 122. The first upper edge spacing G11 is smaller than the first lower edge spacing G12, and the first upper edge spacing G11 and the first lower edge spacing G12 are... The spacing G12 forms the first height H1; similarly, the second arc surface 23 of the second air cushion portion 20 has a second valley bottom reference point 231, which is the center position of the concave valley of the second arc surface 23. The second air cushion portion 20 defines a second reference line L4 tangent to the second valley bottom reference point 231 of the second arc surface 23. The second reference line L4 passes through the second outer side surface 22 and is perpendicular to the central axis L2. The second upper side edge 221 and the second lower side edge 222 of the second outer side surface 22 are located on both sides of the second reference line L4. The second air cushion portion 20 has a second upper edge spacing G21 between the second reference line L4 and the second upper side edge 221, and a second lower edge spacing G22 between the second air cushion portion 20 and the second lower side edge 222. The second upper edge spacing G21 is smaller than the second lower edge spacing G22, and the second upper edge spacing G21 and the second lower edge spacing G22 form the second height H2.

[0141] Therefore, the plurality of first air cushion portions 10 and the plurality of second air cushion portions 20 designed in the three-dimensional curved air cushion module 100 can pivot about the pivot line L1, making the three-dimensional curved air cushion module 100 more flexible in the filling process. When the three-dimensional curved air cushion module 100 is placed into an air cushion molding mold (not shown in the figure) for filling and molding, the three-dimensional curved air cushion module 100 is pivoted about the pivot line L1 to open the first air cushion portions 10 and the second air cushion portions 20 relative to each other, so that the first outer surface 12 of each first air cushion portion 10 and the second air cushion portion 20 are respectively connected. The second outer surface 22 of the 20 is relatively inclined, reducing the maximum height of each of the first air cushion portion 10 and each of the second air cushion portion 20 on the side wall of the air cushion forming mold. In this way, when the plurality of first air cushion portions 10 and the plurality of second air cushion portions 20 are filled and formed, the thickness distribution at the junction of the first outer surface 12 and the first arc surface 13 and the junction of the second outer surface 22 and the second arc surface 23 is stably controlled, reducing the defects generated at the transition points of each of the first air cushion portions 10 and each of the second air cushion portions 20, thereby improving the molding yield of the three-dimensional curved air cushion module 100.

[0142] Please refer to Figure 6 , Figure 7 The curved air cushion product 200 of the second preferred embodiment includes the three-dimensional curved air cushion module 100 of the first embodiment. The curved air cushion product 200 is basically formed by filling the three-dimensional curved air cushion module 100. The curved air cushion product 200 is described in the form of a shoe sole heel air cushion, but it is not limited thereto. The curved air cushion product 200 can also correspond to the overall form of the shoe sole. The three-dimensional curved air cushion module 100 has the plurality of first air cushion parts 10, the plurality of second air cushion parts 20, the plurality of first axial connecting parts 30, the plurality of second axial connecting parts 40 and the lateral connecting part (not shown in the figure). In this second embodiment, each first air cushion part 10 and each second air cushion part 20 are respectively filled with the fluid.

[0143] like Figures 7-10As shown, in the second embodiment, each of the first air cushion portions 10 and each of the second air cushion portions 20 are pivotally arranged side by side along the pivot line L1, and each of the first air cushion portions 10 and each of the second air cushion portions 20 are fixed by a fixing means to obtain the curved air cushion finished product 200. At this time, the second inner side surface 21 and the first inner side surface 11 face each other, and there is a gap P between the first inner side surface 11 and the second inner side surface 21. The central axis L2 is located between the first inner side surface 11 and the second inner side surface 21 and passes through the gap P, so that each of the first air cushion portions 10 The first arc surface 13 and the second arc surface 23 of each of the second air cushion portions 20 face each other, and each of the first arc surface 13 and the second arc surface 23 are adjacent to each other to form a continuous curved surface 110. When the curved air cushion product is used in conjunction with the shoe body, the continuous curved surface of the curved air cushion product can improve the elastic support of the foot blade and the inner side of the foot, providing the wearer with walking comfort. The continuous curved surface 110 can be used to place an insole or a rigid curved panel (not shown in the figure). The rigid curved panel corresponds to the surface contour of the continuous curved surface 110, which provides the wearer with a lighter and more effortless walking experience.

[0144] For detailed instructions, please refer to [link / reference]. Figure 9 When each of the first air cushion portions 10 and each of the second air cushion portions 20 are arranged side by side, the first reference line L3 of each of the first air cushion portions 10 passes through the first valley bottom reference point 131 of the first arc surface 13 and is perpendicular to the central axis L2. The first upper side edge 121 and the first lower side edge 122 of the first outer side surface 12 are located on both sides of the first reference line L3. The second reference line L4 of each of the second air cushion portions 20 passes through the second valley bottom reference point 231 of the second arc surface 23 and is perpendicular to the central axis L2. The second upper side edge 221 and the second lower side edge of the second outer side surface 22 are located on both sides of the first reference line L3. 222 is located on both sides of the second reference line L4, indicating that the connection point between the first arc surface 13 of each first air cushion portion 10 and the first upper edge 121 of the first outer side surface 12 is higher than the first reference line L3, and the connection point between the second arc surface 23 of each second air cushion portion 20 and the second upper edge 221 of the second outer side surface 22 is higher than the second reference line L4. In the continuous curved surface 110, the first arc surface 13 and the second arc surface 23 extend upward in an arc shape from the first inner side surface 11 and the second inner side surface 21 toward the first outer side surface 12 and the second outer side surface 22, respectively.

[0145] In this second embodiment, the fixing means for the first air cushion portion 10 and the second air cushion portion 20 to be arranged side by side is to fill the gap P with an adhesive (not shown in the figure). The adhesive is fixed to the first inner surface 11 of the first air cushion portion 10 and the second inner surface 21 of the second air cushion portion 20, so that the first air cushion portion 10 and the second air cushion portion 20 are joined side by side; in addition, as Figure 7 , Figure 10 As shown, the curved air cushion finished product 200 can, according to the foot pressure distribution of the wearer, select to insert a first support column 120 in the first groove 18 of any two adjacent first air cushion parts 10, and insert a second support column 130 in the second groove 28 of any two adjacent second air cushion parts 20. The arrangement of the first support column 120 and the second support column 130 is used to improve the gait comfort of the wearer when wearing the curved air cushion finished product 200, and the first support column 120 and the second support column 130 are respectively inclined towards the central axis L2.

[0146] In this other embodiment, such as Figure 11 As shown, the fixing means for the first air cushion portion 10 and the second air cushion portion 20 arranged side by side is to surround the three-dimensional curved air cushion module 100 with a frame 210. The frame 210 is a foam material corresponding to the shape of the three-dimensional curved air cushion module 100. The three-dimensional curved air cushion module 100 is placed in a foaming mold, and a foaming material is filled into the foaming mold. The foaming material is integrally foamed in the foaming mold corresponding to the contour of the three-dimensional curved air cushion module 100 to form the frame 210. In this way, the frame 210 can cover and fix the three-dimensional curved air cushion module 100. Please refer to [reference needed]. Figure 12 , Figure 13 The frame 210 has a plurality of first frames 220 and a plurality of second frames 230 corresponding to the number of the plurality of first air cushion parts 10 and the number of the plurality of second air cushion parts 20, respectively. The plurality of first frames 220 are fixed around the plurality of first air cushion parts 10, and the first arc surface 13 and the first connecting surface 14 of each first air cushion part 10 are exposed in each first frame 220. The plurality of second frames 230 are fixed around the plurality of second air cushion parts 20, and the second arc surface 23 and the second connecting surface 24 of each second air cushion part 20 are exposed in each second frame 230. A rib 240 is provided between each first frame 220 and each second frame 230, and each rib 240 is inserted into the gap P between each first air cushion part 10 and each second air cushion part 20.

[0147] Additionally, a first insert 250 is provided between every two adjacent first frames 220, and a second insert 260 is provided between every two adjacent second frames 230. The first insert 250 and the second insert 260 are connected to the rib 240. The first insert 250 is inserted into the first gap 17 between every two adjacent first air cushion portions 10, and a first support post 270 is provided on the first insert 250. The first support post 270 is disposed in the first groove 18 of the first gap 17. The second insert 260 is inserted into the second gap 27 between every two adjacent second air cushion portions 20. The upper part has a second support column 280, which is disposed in the second groove 28 of the second gap 27, thereby eliminating the use of the adhesive. The plurality of first air cushion parts 10 and the plurality of second air cushion parts 20 of the three-dimensional curved air cushion module 100 are fixed to each other and arranged side by side by the frame 210. The frame 210 installed on the three-dimensional curved air cushion module 100 can also fill the gaps and grooves between each pair of adjacent first air cushion parts 10 and each pair of adjacent second air cushion parts 20 to strengthen the support strength of the three-dimensional curved air cushion module 100 and further improve the structural stability of the curved air cushion finished product 200.

[0148] In other embodiments, the curved air cushion finished product 200 can have its structure adjusted as needed. For example, the curved air cushion finished product 200 can correspond to the structure of the three-dimensional curved air cushion module 100 by including at least one first air cushion part 10 and at least one second air cushion part 20. When the curved air cushion finished product 200 includes one first air cushion part 10 and one second air cushion part 20, the three-dimensional curved air cushion module 100 is fixed by the adhesive being disposed in the gap P between the first inner surface 11 of the first air cushion part 10 and the second inner surface 21 of the second air cushion part 20, or... The three-dimensional curved air cushion module 100 is fixed by at least one first frame 220 and at least one second frame 230 of the frame 210 correspondingly fixed around the first air cushion portion 10 and the second air cushion portion 20, with the ribs 240 inserted into the gap P between the first frame 220 and the second frame 230. Alternatively, the three-dimensional curved air cushion module 100 can be fixed by attaching the rigid curved panel to the continuous curved surface 110, so that the plurality of first air cushion portions 10 and the plurality of second air cushion portions 20 of the three-dimensional curved air cushion module 100 are fixed side by side.

[0149] Please refer to Figure 14 , Figure 15The three-dimensional curved surface air cushion module 100' of the third preferred embodiment includes a plurality of first air cushion portions 10', a plurality of second air cushion portions 20', a plurality of first axial connecting portions 30', a plurality of second axial connecting portions 40', a transverse connecting portion 50', a first fluid filling portion 60', and a second fluid filling portion 70'. In this third embodiment, the detailed structures of each first air cushion portion 10', each second air cushion portion 20', each first axial connecting portion 30', each second axial connecting portion 40', and the transverse connecting portion 50' are basically the same as those described in the three-dimensional curved surface air cushion module 100 of the first embodiment. Similarly, for example, the plurality of first air cushion portions 10' are pivotally connected to the plurality of second air cushion portions 20', and the three-dimensional curved air cushion module 100' defines a pivot line L1' located at the pivot position of each first air cushion portion 10' and each second air cushion portion 20', and the plurality of first air cushion portions 10' and the plurality of second air cushion portions 20' are connected side by side corresponding to the direction of the pivot line L1', each of the first axial connecting portions 30' is connected between two adjacent first air cushion portions 10', each of the second axial connecting portions 40' is connected between two adjacent second air cushion portions 20', and the transverse connecting portion 50' is connected between one of the adjacent first air cushion portions 10' and one of the adjacent second air cushion portions 20', and the three-dimensional curved air cushion module 100' is a semi-finished product that has not yet been filled with fluid.

[0150] Each of the first air cushion portions 10' has a first inner side surface 11', a first outer side surface 12', a first arc surface 13', a first connecting surface 14', a first front side surface 15', and a first rear side surface 16'. The first outer side surface 12' has a first upper edge 121' and a first lower edge 122' at both ends. The first arc surface 13' extends upward in an arc shape from the first inner side surface 11' toward the first outer side surface 12' and connects to the first upper edge 121'. The first connecting surface 14' is directly connected to the first lower edge 122' and the first inner side surface 11' of the first outer side surface 12' relative to the first arc surface 13'. The first front side surface 15' and the first rear side surface 16' are connected to the first inner side surface 11', the first outer side surface 12', the first arc surface 13', and the first connecting surface 14' in the direction of the pivot line L1'. The plurality of first air cushion portions 10' are coplanarly connected to the plurality of first outer side surfaces 12' via the plurality of first connecting surfaces 14'.

[0151] The first fluid filling part 60' is disposed on the first front side 15' of the uppermost first air cushion part 10'. The first fluid filling part 60' is an air nozzle, and the plurality of first air cushion parts 10' are connected through the plurality of first axial connecting parts 30'. The first fluid filling part 60' is used to controllably fill the plurality of first air cushion parts 10' with fluid. However, in other embodiments, the first fluid filling part 60' can be arbitrarily adjusted and disposed on one of the first air cushion parts 10', or the number of the first fluid filling parts 60' can be multiple corresponding to the plurality of first air cushion parts 10', and the plurality of first fluid filling parts 60' are respectively disposed on the plurality of first air cushion parts 10'.

[0152] Each of the second air cushion portions 20' has a second inner side surface 21', a second outer side surface 22', a second arc surface 23', a second connecting surface 24', a second front side surface 25', and a second rear side surface 26'. The first inner side surface 11' and the second inner side surface 21' face each other. The two ends of the second outer side surface 22' have a second upper edge 221' and a second lower edge 222'. The second arc surface 23', corresponding to the outline and position of the first arc surface 13', extends upwardly in an arc shape from the second inner side surface 21' towards the second outer side surface 22' and connects to the second upper edge 221'. The second connecting surface 24' is directly connected to the second lower side edge 222' and the second inner side surface 21' of the second outer side surface 22' relative to the second arc surface 23', and the second connecting surface 24' is adjacent to the first connecting surface 14'. The second front side surface 25' and the second rear side surface 26' are connected to the second inner side surface 21', the second outer side surface 22', the second arc surface 23' and the second connecting surface 24' in the direction of the pivot line L1', and the plurality of second air cushion portions 20' are coplanarly connected with the plurality of second connecting surfaces 24' and the plurality of second outer side surfaces 22'.

[0153] The second fluid filling part 70' is disposed on the second front side 25' of the uppermost second air cushion part 20' relative to the first fluid filling part 60'. The second fluid filling part 70' is also an air nozzle, and the plurality of second air cushion parts 20' are connected through the plurality of second axial connecting parts 40'. The second fluid filling part 70' is used to controllably fill the plurality of second air cushion parts 20' with fluid. However, in other embodiments, the second fluid filling part 70' can be arbitrarily adjusted and disposed on one of the second air cushion parts 20', or the number of the second fluid filling parts 70' can be multiple corresponding to the plurality of second air cushion parts 20', and the plurality of second fluid filling parts 70' are respectively disposed on the plurality of second air cushion parts 20'.

[0154] like Figure 16As shown, the three-dimensional curved air cushion module 100' pivots the first air cushion portion 10' and the second air cushion portion 20' relative to each other along the pivot line L1', causing each of the first outer side surfaces 12' and each of the second outer side surfaces 22' to be relatively inclined. At this time, there is a first height H1' between the first upper side edge 121' and the first lower side edge 122', which is less than the wall height D1' of the first outer side surface 12'. There is a second height H2' between the second upper side edge 221' and the second lower side edge 222', which is less than the wall height D2' of the second outer side surface 22'. Therefore, the three-dimensional curved air cushion module 100' is filled and molded. The fluid can be directly filled into the plurality of first air cushion parts 10' and the plurality of second air cushion parts 20' through the first fluid filling part 60' and the second fluid filling part 70'. Moreover, the three-dimensional curved air cushion module 100' pivots each of the first air cushion parts 10' and each of the second air cushion parts 20' relative to each other by the pivot line L1', so that the first outer side surface 12' of each of the first air cushion parts 10' and the second outer side surface 22' of each of the second air cushion parts 20' are relatively inclined. This can also reduce the maximum height of each of the first air cushion parts 10' and each of the second air cushion parts 20' on the side wall of the air cushion forming mold, thereby improving the forming yield of the three-dimensional curved air cushion module 100'.

[0155] Please refer to Figure 17 The curved air cushion product 300 of the fourth preferred embodiment includes the three-dimensional curved air cushion module 100' of the aforementioned third embodiment. The shape of the curved air cushion product 300 is substantially the same as that of the curved air cushion product 200 of the aforementioned second embodiment. In this fourth embodiment, each of the first air cushion portions 10' and each of the second air cushion portions 20' are respectively filled with the fluid.

[0156] like Figure 18 , Figure 19As shown, in the fourth embodiment, the three-dimensional curved air cushion module 100' pivots along the pivot line L1', with each of the first air cushion portions 10' and each of the second air cushion portions 20' facing each other side-by-side. Each of the first air cushion portions 10' and each of the second air cushion portions 20' is fixed by a fixing means to obtain the finished curved air cushion 300. The fixing means of the three-dimensional curved air cushion module 100' can be processed using the adhesive or the frame (not shown) used in the aforementioned second embodiment. At this time, each of the second air cushions... The second inner surface 21' and the second arc surface 23' of part 20' face each other and the first inner surface 11' and the first arc surface 13' of each of the first air cushion parts 10' respectively. The first arc surface 13' and the second arc surface 23' are adjacent to each other to form a continuous curved surface 110'. In the continuous curved surface 110', the first arc surface 13' and the second arc surface 23' extend upward in an arc shape from the first inner surface 11' and the second inner surface 21' toward the first outer surface 12' and the second outer surface 22' respectively.

[0157] in addition, Figure 20 The method for fixing the curved air cushion finished product 300 is to integrally foam and combine it with the three-dimensional curved air cushion module 100' using a foamed shoe body 400. This embodiment uses the combination of the curved air cushion finished product 300 and the foamed shoe body 400 to form a shoe outsole as an example. The curved air cushion finished product 300 is placed in a foaming mold, and then a foaming material is filled into the foaming mold to integrally foam and form the foamed shoe body 400. The foamed shoe body 400 covers and fixes the three-dimensional curved air cushion module 100' according to the contours of the plurality of first air cushion parts 10' and the plurality of second air cushion parts 20'. Please refer to [reference needed]. Figure 21 , Figure 22The heel portion 410 of the foamed shoe body 400 has a plurality of grooves 420 corresponding to the outlines and arrangement of the plurality of first air cushion portions 10' and the plurality of second air cushion portions 20' in the curved air cushion finished product 300. The plurality of first air cushion portions 10' and the plurality of second air cushion portions 20' are respectively fixed in the plurality of grooves 420, and the groove walls of the plurality of grooves 420 are correspondingly embedded in the plurality of first gaps 17' and the plurality of first clamping grooves 18' of the plurality of first air cushion portions 10' and the plurality of first gaps 27' and the plurality of first clamping grooves 28' of the plurality of second air cushion portions 20'. Each of the multiple accommodating slots 420 has an opening 430 on one side. When the curved air cushion finished product 300 is installed on the heel portion 410 of the foamed shoe body 400, the first outer side 12' of each of the first air cushion portions 10' and the second outer side 22' of each of the second air cushion portions 20' are exposed in the side opening 430 of each of the accommodating slots 420. The curved air cushion finished product 300 can provide elastic support for the foamed shoe body 400, and the side opening 430 of the foamed shoe body 400 can laterally expose the appearance and color of the multiple first air cushion portions 10' and the multiple second air cushion portions 20', increasing the visual aesthetics of the foamed shoe body 400.

[0158] Please refer to Figure 23 The fifth preferred embodiment of the three-dimensional curved surface air cushion module 500 includes a plurality of first air cushion portions 510, a plurality of second air cushion portions 520, a plurality of first axial connecting portions 530, a plurality of second axial connecting portions 540, a first fluid filling portion 550, and a second fluid filling portion 560.

In this fifth embodiment, as... Figure 24 As shown, the plurality of first air cushion portions 510 and the plurality of second air cushion portions 520 are independent components and are not connected to each other.

[0159] like Figure 24 , Figure 25As shown, each of the first air cushion portions 510 has a first inner side surface 511, a first outer side surface 512, a first arc surface 513, and a first connecting surface 514. The first inner side surface 511 and the first outer side surface 512 are located opposite each other on both sides of the first air cushion portion 510. The first arc surface 513 extends upwardly in an arc shape from the first inner side surface 511 toward the first outer side surface 512. The first connecting surface 514 is directly connected to the first outer side surface 512 and the first inner side surface 511 relative to the first arc surface 513. The plurality of first air cushion portions 510 are coplanarly connected to the plurality of first outer side surfaces 512 by the plurality of first connecting surfaces 514. In addition, every two adjacent first air cushion portions... A first gap 517 is provided between the parts 510, and a first clamping groove 518 is provided between each two adjacent first air cushion parts 510, passing through the first arc surface 513 toward the first connecting surface 514 in the first gap 517. Each first axial connecting part 530 is provided in the first gap 517 between two adjacent first air cushion parts 510, and each first axial connecting part 530 connects a first front side surface 515 of one first air cushion part 510 and a first rear side surface 516 of the adjacent other first air cushion part 510. The first fluid filling part 550 is provided on the first front side surface 515 of the uppermost first air cushion part 510 for operatively filling the plurality of first air cushion parts 510 with fluid.

[0160] Each of the second air cushion portions 520 has a second inner side surface 521, a second outer side surface 522, a second arc surface 523, and a second connecting surface 524. The second inner side surface 521 and the second outer side surface 522 are located opposite each other on both sides of the second air cushion portion 520. The outline of the second arc surface 523 corresponding to the first arc surface 513 extends upwardly in an arc shape from the second inner side surface 521 toward the second outer side surface 522. The second connecting surface 524 is directly connected to the second outer side surface 522 and the second inner side surface 521 relative to the second arc surface 523. The plurality of second air cushion portions 20 are coplanarly connected to the plurality of second outer side surfaces 23 by the plurality of second connecting surfaces 24. In addition, every two phases A second gap 527 is provided between adjacent second air cushion portions 520. A second clamping groove 528 is provided between each two adjacent second air cushion portions 520, passing through the second arc surface 523 toward the second connecting surface 524 in the second gap 527. Each second axial connecting portion 540 is provided in the second gap 527 between two adjacent second air cushion portions 520, and each second axial connecting portion 540 connects a second front side surface 525 of one second air cushion portion 520 and a second rear side surface 526 of the adjacent second air cushion portion 520. The second fluid filling portion 560 is provided in the second front side surface 525 of the uppermost second air cushion portion 520 for operatively filling the plurality of second air cushion portions 520 with fluid.

[0161] In other embodiments, the structure and arrangement of the three-dimensional curved air cushion module 500 can be adjusted as needed. For example, the three-dimensional curved air cushion module 500 may omit the provision of the plurality of first axial connecting portions 530 and the plurality of second axial connecting portions 540, as long as each first air cushion portion 510 and each second air cushion portion 520 can be independently filled with fluid. It is not limited that two adjacent first air cushion portions 510 and two adjacent second air cushion portions 520 are interconnected. The number of first air cushion portions 510 and the number of second air cushion portions 520 may be at least one. The first fluid filling portion 550 and the second fluid filling portion 560 may also be omitted.

[0162] In this fifth embodiment, when the three-dimensional curved air cushion module 500 is actually filled and molded, the plurality of first air cushion parts 510 and the plurality of second air cushion parts 520 are respectively placed in an air cushion molding mold (not shown in the figure), and the plurality of first air cushion parts 510 and the plurality of second air cushion parts 520 are placed obliquely in a molding cavity of the air cushion molding mold, so that the first outer side surface 512 of each first air cushion part 510 and the second outer side surface 522 of each second air cushion part 520 are respectively obliquely arranged, thereby reducing the maximum height of each first air cushion part 510 and each second air cushion part 520 on the side wall of the air cushion molding mold, and the filling pressure of the plurality of first air cushion parts 510 and the plurality of second air cushion parts 520 can be independently adjusted according to the needs.

[0163] Please refer to Figure 26 The curved air cushion product 600 of the sixth preferred embodiment includes the three-dimensional curved air cushion module 500 of the fifth embodiment. The shape of the curved air cushion product 600 is substantially the same as that of the curved air cushion product 300 of the fourth embodiment. In this sixth embodiment, each of the first air cushion portions 510 and each of the second air cushion portions 520 are respectively filled with the fluid.

[0164] like Figures 26-28 As shown, in the sixth embodiment, the three-dimensional curved air cushion module 500 is connected side-by-side to the first air cushion portion 510 and the second air cushion portion 520 by a fixing means. The fixing means of the three-dimensional curved air cushion module 500 can be processed using the adhesive or the frame (not shown) used in the aforementioned second embodiment, so that the second inner surface 521 and the second arc surface 523 of each second air cushion portion 520 and the first inner surface 511 and the first arc surface 513 of each first air cushion portion 510 face each other, and the first arc surface 513 and the second arc surface 523 are adjacent to each other to form a continuous curved surface 570. The curved surface shape of the continuous curved surface 570 is approximately the same as the continuous curved surface 110' of the aforementioned fourth embodiment; as... Figure 27, Figure 28 As shown, when the first air cushion portion 510 and the second air cushion portion 520 are connected side by side, the second connecting surface 524 is adjacent to the first connecting surface 514. The three-dimensional curved air cushion module 500 defines a dividing line L5 located between the first connecting surface 514 and the second connecting surface 524. The plurality of first air cushion portions 510 and the plurality of second air cushion portions 520 are connected side by side corresponding to the direction of the dividing line L5. The three-dimensional curved air cushion module 500 defines a central axis L6 between the first air cushion portion 510 and the second air cushion portion 520, which passes through the dividing line L5. The central axis L6 is located between the first inner surface 511 and the second inner surface 521.
