In this embodiment, the modeling layer 140 includes a plurality of connecting portions 141 and a plurality of protruding portions 142. The protruding portions 142 and the connecting portions 141 are staggered, and the edges 143 of each protruding portion 142 are spaced apart from the base layer 110. The base layers 110 collectively define the opening O. Specifically, in this embodiment, the accommodation space S is located between the protruding portion 142 of the modeling layer 140 and the base layer 110 , so that the protruding portion 142 has a three-dimensional structure protruding from the base layer 110 . More specifically, in this embodiment, the modeling layer 140 includes a plurality of three-dimensional units R1. In Figure 2, the range of a three-dimensional unit R1 is illustratively marked with a dotted line. Each three-dimensional unit R1 includes a protruding part 142 and a first connecting sub-part 147, a second connecting sub-part 148 and a third connecting sub-part. Department 149. The first connecting sub-portion 147 is disposed on the first side of the raised portion 142 , the second connecting sub-portion 148 is disposed on the second side of the raised portion 142 , and the third connecting sub-portion 149 is disposed on the third side of the raised portion 142 , where the first side is opposite to the second side, and the third side is connected between the first side and the second side. The modeling layer 140 is connected to the base layer 110 through the first connecting sub-part 147, the second connecting sub-part 148 and the third connecting sub-part 149 of the three-dimensional unit R1.

In this embodiment, the left half and the right half of the modeling layer 140 respectively include a plurality of three-dimensional units R1.

The connecting sub-parts 148 together constitute the connecting part 141, and the sizes of the plurality of three-dimensional units R1 decrease from the center of the modeling layer 140 to the left and right sides. However, the present invention is not limited to this, and the configuration of the three-dimensional unit R1 can be flexibly adjusted according to actual needs (such as the desired shape design or visual aesthetics). For example, a plurality of three-dimensional units R1 may be independent of each other and not connected. That is, there may be a separation distance between two adjacent three-dimensional units R1 (not shown in the figure), and any two adjacent three-dimensional units R1 The distance between them can be the same or different. For another example, among the plurality of three-dimensional units R1, only some of the three-dimensional units R1 are connected to each other, but the other part of the three-dimensional units R1 are independent of each other and not connected to each other. For another example, the modeling layer 140 may also include only one three-dimensional unit R1.

In this embodiment, the material of the modeling layer 140 can be thermoplastic resin, such as thermoplastic polyurethane (TPU). In this way, the modeling layer 140 can be directly connected to the base layer 110 through heating and pressure. However, in other embodiments, the modeling layer 140 can also be connected to the base layer 110 through other methods such as adhesive, microwave welding or ultrasonic welding. For example, the modeling layer 140 can also be connected to the base layer 110 by applying hot melt glue and using a hot pressing method.

Upper layer structure 100 optionally includes a reinforcement layer 130 . The reinforcement layer 130 is attached to the modeling layer 140 and is disposed between the base layer 110 and the modeling layer 140, as shown in Figure 2 . The reinforcing layer 130 can provide a function of strengthening the structural strength of the modeling layer 140 . As shown in FIGS. 3 and 4 , at least part of the reinforcing layer 130 and the modeling layer 140 overlap. As shown in FIG. 4 , at least a portion of the edge 134 of the reinforcement layer 130 is spaced apart from the base layer 110 , and at least the portion of the edge 134 of the reinforcement layer 130 can be connected to at least a portion of the edge 144 of the styling layer 140 (ie, corresponding to the opening O portions) aligned, whereby the reinforcing layer 130 can provide a supporting effect for at least the portion of the edge 144 of the styling layer 140 . The modeling layer 140 can completely cover the reinforcement layer 130 , as illustrated in this embodiment, to prevent the reinforcement layer 130 from affecting the visual and modeling effects provided by the modeling layer 140 . The hardness of the strengthening layer 130 may be greater than the hardness of the modeling layer 140 . The reinforcing layer 130 can be made of thermoplastic resin, such as thermoplastic polyurethane, whereby the reinforcing layer 130 can be directly connected to the modeling layer 140 through heating and pressure. However, in other embodiments, the reinforcement layer 130 can also be connected to the modeling layer 140 through other methods such as adhesive, microwave welding or ultrasonic welding. For example, the reinforcing layer 130 can also be connected to the modeling layer 140 by applying hot melt glue and using a hot pressing method. According to an embodiment of the present invention, both the reinforcing layer 130 and the modeling layer 140 can be made of thermoplastic resin, thereby helping to improve the adhesion strength between the reinforcing layer 130 and the modeling layer 140 with appropriate heating and pressurizing time. .

Please refer to Figure 2 again. In this embodiment, the reinforcement layer 130 includes a plurality of bridge portions 131 and a plurality of support portions 132. The support portions 132 and the bridge portions 131 are staggered. The edges 133 of each support portion 132 are in contact with the base layer 110. The accommodation space S is spaced apart from each other, and is located between the support portion 132 of the reinforcement layer 130 and the base layer 110 , as shown in FIGS. 3 and 4 . Specifically, in this embodiment, the bridge portion 131 of the reinforcing layer 130 corresponds to the connecting portion 141 of the modeling layer 140, the supporting portion 132 of the reinforcing layer 130 corresponds to the protruding portion 142 of the modeling layer 140, and the edge 133 of the supporting portion 132 and The edges 143 of the raised portions 142 are aligned.

In this embodiment, the shape of the reinforcing layer 130 can correspond to the shape of the modeling layer 140, thereby providing a more complete structural strengthening effect to the modeling layer 140. Taking this embodiment as an example, the reinforcement layer 130 includes two pieces (such as the left half piece and the right half piece shown in Figure 2, not otherwise labeled). The shape of the two-piece arrangement roughly corresponds to the shape of the modeling layer 140 and is also U-shaped, but the invention is not limited thereto. For example, the reinforcement layer 130 may only include one piece (not shown), and this single piece The shape of the body generally corresponds to the shape of the modeling layer 140 and is U-shaped.

The shoe layer structure 100 optionally includes a cover layer 120, which is attached to the base layer 110 and disposed between the base layer 110 and the styling layer 140, as shown in FIG. 2 . The covering layer 120 can provide functions of decorating and reinforcing the base layer 110 . As shown in Figure 4, the covering layer 120 extends into the opening O/accommodating space S, and within the scope of the accommodating space S, the projection of the covering layer 120 on the base layer 110 is the same as the projection of the strengthening layer 130/modeling layer 140 on the base. The projections of the layer 110 partially overlap, however, the present invention is not limited thereto. In other embodiments, the covering layer 120 can extend into the opening O/accommodating space S, and within the scope of the accommodating space S, the projection of the covering layer 120 on the base layer 110 is the same as the projection of the reinforcing layer 130/modeling layer 140 on the base layer. The projection of the layer 110 may be completely overlapping; alternatively, the edge of the covering layer 120 may be aligned with the opening O but not extend into the accommodating space S, and within the scope of the accommodating space S, the projection of the covering layer 120 on the base layer 110 The projection of the reinforcement layer 130/modeling layer 140 on the base layer 110 does not overlap. By extending the covering layer 120 into the opening O/accommodating space S, it is helpful for the viewer to see the covering layer 120 instead of the base layer 110 when looking in the direction of the accommodating space S at the opening O. , which can provide a sense of visual continuity. The shape of the covering layer 120 may correspond to the shape of the modeling layer 140. Taking this embodiment as an example, the shape of the covering layer 120 generally corresponds to the shape of the modeling layer 140 and is U-shaped. In this embodiment, the covering layer 120 and the modeling layer 140 form a modeling pattern P1 including a three-dimensional structure. The material of the covering layer 120 can be thermoplastic resin, such as thermoplastic polyurethane, whereby the covering layer 120 can be directly connected to the base layer 110 through heating and pressure. However, in other embodiments, the cover layer 120 can also be connected to the base layer 110 through other methods such as adhesive, microwave welding or ultrasonic welding. For example, the cover layer 120 can also be connected to the base layer 110 by applying hot melt glue and using a hot pressing method.

According to an embodiment of the present invention, the material of the covering layer 120 can be the same as the material of the modeling layer 140 (for example, the modeling layer 140 and the covering layer 120 have similar softening points and melting points), and the material of the base layer 110 can be the same as that of the modeling layer 140 . The materials are different (for example, the softening point and melting point of the base layer 110 may be higher than the modeling layer 140 and the covering layer 120 ). Thereby, when the covering layer 120 and the modeling layer 140 are connected to the base layer 110 through heating and pressing, it is helpful to set better process parameters such as heating temperature, pressing pressure and duration.

Please refer to Figure 5, which is a schematic cross-sectional view of a shoe surface layer structure 100a according to another embodiment of the present invention. The perspective is the same as Figure 4. The main difference between the shoe surface layer structure 100a and the shoe surface layer structure 100 is that the base layer 110a further includes a through hole 111a. The through hole 111a is located in the overlapping area of the modeling layer 140 and the base layer 110a, and the through hole 111a and the accommodation space S are mutually exclusive. Connected. Specifically, in this embodiment, the through hole 111a is located within the projection range of the protruding portion 142 on the base layer 110a. This configuration is beneficial to improving the ventilation of the shoes made of the upper layer structure 100a. For example, when the material of the base layer 110a is a relatively air-impermeable material such as leather or artificial leather, the gas located on the side 112a of the base layer 110a where the modeling layer 140 is not provided can be released through the through hole 111a (for example: The gas in the foot space in the shoe circulates to the outside through the exhaust path of the through hole 111a, the accommodation space S, and the opening O, thereby improving ventilation. In addition, because the through hole 111a is located within the projection range of the protruding portion 142 of the modeling layer 140 on the base layer 110a, the modeling layer 140 can block the liquid (not shown) falling from above and prevent the liquid from passing through the through hole 111a. It flows to the side 112a of the base layer 110a where the modeling layer 140 is not provided (for example, the foot space inside the shoe), thereby providing a simple waterproof function without affecting the aforementioned ventilation function.

Please refer to Figures 6 and 7. Figure 6 is a schematic top view of the shoe surface layer structure 100b according to yet another embodiment of the present invention. Figure 7 is a schematic diagram of the shoe surface layer structure 100b along the cut plane line C-C in Figure 6. schematic cross-section diagram. The upper layer structure 100b includes a base layer 110 and a styling layer 140b. The modeling layer 140b is provided on the base layer 110. At least a part of the modeling layer 140b is connected to the base layer 110 and jointly defines an accommodation space S with the base layer 110. At least a part of the edge of the modeling layer 140b is spaced apart from the base layer 110. The base layers 110 jointly define an opening O, and the opening O and the accommodation space S are connected with each other.

Here, the ranges of the first region A1 and the second region A2 are separated by dotted lines. The first region A1 and the second region A2 respectively include a plurality of connecting portions 141b and a plurality of protruding portions 142b. The protruding portions 142b and the connecting portions 141b intersect. It is provided that the edge 143b of each protrusion 142b is spaced apart from the base layer 110 and defines the opening O together with the base layer 110 . The modeling layer 140b forms a modeling pattern P2 including a three-dimensional structure. In this embodiment, the body of the modeling layer 140b includes a plurality of edges (different from the outer edges of the modeling layer 140b), that is, the edges 143b of the protruding portion 142b. The edge 143b can be cut by a cutting tool (such as a laser, a knife, etc.) to cut the inner area on the sheet body of the modeling layer 140b (such as the modeling layer 140b' shown in Figure 10), so that A plurality of edges that are different from the outer contour are manufactured within the scope of the sheet body (for example: edge 143b' shown in Figure 10).

Other details of the shoe surface layer structure 100b can be the same as the aforementioned shoe surface layer structures 100 and 100a unless there is any contradiction, and will not be described again here.

This helps to align the various components in the stacked assembly 300, and helps to accurately form the three-dimensional units of the stacked structure at predetermined positions.

Next, the stacking assembly 300 is pressed and heated (corresponding to step 820), so that at least a part of the modeling layer 140' is connected to the base layer 110 to form a laminated structure (for example: the ones shown in Figures 1, 3, and 4). The upper layer structure of the shoe is shown 100). In this embodiment, the pressure and heating stacking assembly 300 further includes adhering the reinforcement layer 130' to the modeling layer 140', and adhering the cover layer 120' to the base layer 110. In this embodiment, after the modeling layer 140' passes through step 820, its protruding portion 142' is shaped by the partition 220 and transforms from a planar structure into a three-dimensional structure protruding relative to the base layer 110 (for example: the protruding portion 142 ), which means that the modeling layer 140' can be transformed from a planar structure into a modeling layer 140 containing a three-dimensional structure. Similarly, after the reinforcement layer 130' passes step 820, its support portion 132' is shaped by the partition 220 and transforms from a planar structure into a three-dimensional structure (for example, the support portion 132) that is raised relative to the base layer 110, which means that the reinforcement layer 130' is strengthened. The layer 130' can be transformed from a planar structure into a reinforced layer 130 including a three-dimensional structure. After the covering layer 120' passes through step 820 and is heated, melted or softened, it can be transformed from a film originally separated from the base layer 110 into a covering layer 120 fixed to the base layer 110. The base layer 110 and the molded part 200 do not change before and after step 820.

Finally, remove the molded part (corresponding to step 830), and then cut off the excess parts of the laminated structure (for example, the first positioning parts 145', 121') to complete the production of the shoe surface laminated structure 100. When the modeling layer 140' does not include the first positioning part 145' and the covering layer 120' does not include the first positioning part 121', the laminated structure formed after step 830 is the shoe surface layered structure 100. For details about the laminated structure, please refer to the relevant description of the shoe surface laminated structure 100 and will not be described again here.

Here, the first area A1' and the second area A2' are separated by a dotted line. The first area A1' and the second area A2' respectively include a plurality of connecting portions 141b' and a plurality of protruding portions 142b'. The protruding portions 142b' and the connecting portion 141b' are arranged alternately. When forming the overlay combination 300b, it includes making the connecting portion 141b' and the connecting portion 210a in the first area A1' correspond to each other, and making the protruding portion 142b' and the partitioning portion 220a in the first area A1' correspond to each other, and making The connecting portion 141b' and the connecting portion 210b in the second area A2' correspond to each other, and the protruding portion 142b' and the separation portion 220b in the second area A2' correspond to each other. More specifically, in this embodiment, at least part of the partitions 220a and 220b is inserted into the space between the lower part of the raised part 142b' and the upper part of the base layer 110, thereby separating the raised part 142b' from the base layer 110. .

In this embodiment, the body of the modeling layer 140b' includes a plurality of edges 143b' (different from the outer edges of the modeling layer 140b'). The edge 143b' can be formed by cutting the inner area of the modeling layer 140b' with a cutting tool (eg, laser, knife, etc.). The modeling layer 140b' is made of a material that can be melted by heat, such as thermoplastic resin. In this way, through step 820, the modeling layer 140b' can be directly connected to the base layer 110 through a hot-melt connection, without the need to connect each other through other components (such as adhesives), and the modeling layer 140b' can also be connected to each other through a hot melt connection. Each protruding portion 142b' is shaped by the partitions 220a and 220b to form a three-dimensional structure that is relatively protruding from the base layer 110 (for example: the protruding portion 142b shown in Figure 6). In other embodiments, the modeling layer 140b' can also be connected to the base layer 110 through other methods such as adhesive, microwave welding or ultrasonic welding.

Next, the stacking assembly 300b is pressed and heated (corresponding to step 820), so that at least a part of the modeling layer 140b' is connected to the base layer 110 to form a laminated structure (for example: the shoe surface laminated structure 100b shown in Figure 6) . In this embodiment, after the modeling layer 140b' passes through step 820, its raised portion 142b' is shaped by the partitions 220a and 220b to form a three-dimensional structure that is raised relative to the base layer 110 (for example, the raised portion 142b). That is to say, the modeling layer 140b' is transformed from a planar structure to a modeling layer 140b containing a three-dimensional structure. After step 820, the connection portion 141b' of the modeling layer 140b' can be transformed into the connection portion 141b fixed to the base layer 110. The base layer 110, the first molded part 200a and the second molded part 200b do not change before and after step 820. Finally, the first molded part 200a and the second molded part 200b are removed (corresponding to step 830) to complete the production of the upper layer structure 100b.
