[0030] In order to better understand the purpose, structure and function of the utility model, the support piece of the utility model is described in detail below in combination with the drawings.

[0031] As Figure 1 shown, the side of the shoe sole body close to the inner side of human foot is defined as the inner side of the shoe sole body, the side of the shoe sole body close to the outer side of human foot is defined as the outer side of the shoe sole body, the connecting direction of the inner side and the outer side is defined as the horizontal direction, the end of the shoe sole body close to the human toe is defined as the front side of the shoe sole body, the end of the shoe sole body close to the human heel is defined as the rear side of the shoe sole body, and the connecting direction of the front side and the rear side is defined as the vertical direction.

[0032] The support component is mounted on the sole and includes a forefoot area. A first reinforcing rib is coupled to the forefoot area and is arranged longitudinally to enhance the rigidity of the forefoot area of ​​the support component. At the same time, at least one slit is arranged transversely on the first reinforcing rib. The slit is a through-type slit structure, and the slit position corresponds to the force position of the forefoot area of ​​the human foot during the push-off phase. The slit structure separates the first reinforcing rib in the longitudinal direction and extends the length of the first reinforcing rib in the longitudinal direction, which can further reduce the rigidity of the first reinforcing rib in the unidirectional bending state, thereby reducing the rigidity of the forefoot area of ​​the support component. This makes the forefoot area of ​​the support component highly resilient and easy to bend in one direction.

[0033] It should be noted that the coupling described in this utility model is a connection method, including both direct fixed connections between different structures and indirect connections between different structures. The unidirectional bending described in this utility model refers to the downward bending state formed when the forefoot area of ​​the support member is subjected to a downward force during the push-off phase. This bending occurs as follows: the middle part of the forefoot area moves away from the sole of the foot, while the front and rear sides of the forefoot area move towards the sole of the foot.

[0034] To better understand the purpose, structure, and function of this utility model, the following detailed description of the support component, taking the specific structure of the support component as an example, is provided in conjunction with the accompanying drawings.

[0035] Example 1, as Figures 1 to 4 As shown, the support member includes a forefoot region 110, a midfoot region 120, and a heel region connected in sequence. Three first reinforcing ribs 130 are arranged longitudinally on the forefoot region 110. The number of first reinforcing ribs 130 can be reduced or increased according to the thickness and rigidity of the forefoot region 110. In this embodiment, the arrangement of three ribs is a preferred option that is adapted to the thickness of the forefoot region 110 described below, which can provide suitable support strength for the forefoot region 110 of the support member. If there is one more rib, the rigidity will be too large and it will not be easy to bend. If there is one less rib, the rigidity will be insufficient and the support effect will be poor.

[0036] The forefoot region 110 of the support member includes a top surface facing the sole of the human foot and a bottom surface 111 facing the ground. The first reinforcing rib 130 protrudes in the direction of the bottom surface 111 of the forefoot region 110. The purpose of this structure is that when the forefoot region 110 of the support member is subjected to a downward force during the push-off stage, the middle part of the forefoot region 110 of the support member will move away from the sole of the human foot, and the front side and the rear side will move towards the sole of the human foot, i.e. form a downward protruding one-way bending state. The protrusion of the first reinforcing rib 130 in the direction of the bottom surface 111 of the forefoot region 110 helps the first reinforcing rib 130 to extend in the longitudinal direction, so that the forefoot region 110 of the support member is easy to deform. If the middle part of the first reinforcing rib 130 bends towards the human foot, the first reinforcing rib 130 will be pressed in the longitudinal direction, preventing further bending, i.e. the above structure can achieve the technical effect that the forefoot region 110 of the support member is easy to bend in one direction.

[0037] As shown in Figure 2 The first reinforcing rib 130 is provided with a plurality of cuts 131 in the transverse direction. The cuts 131 are through slits. The slits separate the first reinforcing rib 130 in the longitudinal direction, extend the length of the first reinforcing rib 130 in the longitudinal direction, further reduce the rigidity of the first reinforcing rib 130 in the above-mentioned one-way bending state, and further reduce the rigidity of the forefoot region 110 of the support member, so that the forefoot region 110 of the support member is more easy to bend in one direction. The number of cuts 131 can be set according to actual needs. In the present embodiment, four cuts 131 are provided on each first reinforcing rib 130, which is a preferred solution matched with the thickness of the forefoot region 110 and the thickness of the first reinforcing rib 130 in the present embodiment. It can provide a suitable bending radius for the forefoot region 110 of the support member. More cuts will cause excessive bending, and fewer cuts will make the first reinforcing rib 130 too rigid to bend. Moreover, the four cuts 131 are evenly distributed at the position of the human forefoot where the force is applied during the push-off stage, which can provide better bending efficiency.

[0038] Further, the forefoot region 110 of the support member further comprises a reinforcing assembly 140. The reinforcing assembly 140 is a layered structure, which is fixedly arranged on the bottom surface 111 of the forefoot region 110 by coating, and is arranged in the longitudinal direction on the inner side and the outer side of the first reinforcing rib 130. The reinforcing assembly 140 can keep its own structure stable, and can form a traction force on the front side and the rear side of the forefoot region 110 of the support member in the one-way bending state, so that the forefoot region 110 of the support member is not easy to break, and can further quickly recover to the initial state after one-way bending.

[0039] The reinforcing component 140 is made of polyimide and / or polyarylate, which take advantage of the fact that both have good heat resistance and remain stable in a high temperature range, as well as good mechanical strength. Therefore, when the forefoot area 110 of the support is repeatedly bent at different temperatures, the reinforcing component 140 can always provide reliable physical support and excellent dimensional stability because the material shape and size change very little.

[0040] Furthermore, the support component is a sheet-like structure. The direction between the top and bottom surfaces 111 of the forefoot area 110 of the support component is defined as vertical, and the length of the vertical direction is defined as thickness. The thickness of the forefoot area 110 of the support component is 0.8mm-1mm, of which the thickness on the front side near the toes is 0.8mm, and the thickness at other locations of the forefoot area 110 is 1mm. The thickness of the first reinforcing rib 130 is 3mm-4mm. The distance between the cut 131 near the front side and near the rear side of the sole body is defined as the width of the cut 131. The width of the cut 131 is set to 0.2mm-0.5mm. These parameter settings, combined with the above-mentioned preferred scheme of the number of reinforcing ribs and the number of cuts 131, achieve the technical effect that the forefoot area 110 of the support component is easy to bend in one direction, not easy to break, and can quickly restore its initial shape.

[0041] Preferably, three second reinforcing ribs 150 are provided on the midfoot region 120 of the support member. The second reinforcing ribs 150 are connected one-to-one with the three first reinforcing ribs 130 on the forefoot region 110. That is, the second reinforcing ribs 150 extend along the end of the first reinforcing ribs 130 near the rear side of the sole body, so that the force of the first reinforcing ribs 130 when the forefoot region 110 of the support member is bent in one direction is linearly transmitted to the midfoot region 120, reducing the risk of the forefoot region 110 breaking, making the force transmission of the sole of the foot smoother during the push-off phase, and improving the comfort and stability during exercise.

[0042] Example 2, as Figures 5 to 9 As shown, the support includes a second support plate 200, which includes a forefoot region 210, a midfoot region 220, and a heel region connected in sequence. A first support plate 230 is disposed on the forefoot region 210 of the second support plate 200. The forefoot region 210 of the second support plate 200 includes a top surface facing the bottom of the human foot and a bottom surface 211 facing the ground. The first support plate 230 includes a first surface facing the bottom of the human foot and a second surface 231 facing the ground. The first surface of the first support plate 230 is disposed opposite to the bottom surface 211 of the forefoot region 210 of the second support plate 200. The two are fixedly connected by adhesive to achieve synchronous unidirectional bending.

[0043] Two hollow grooves 212 are arranged on the forefoot region 210 of the second support plate 200, and two first reinforcing ribs 240 are arranged on the first support plate 230, the first reinforcing ribs 240 protrude in the direction of the second surface 231 of the first support plate 230, i.e. in the direction of the ground, and the first reinforcing ribs 240 and the grooves 212 are longitudinally arranged one by one, which is arranged for the purpose of when the forefoot region 210 of the second support plate 200 is subjected to downward force in the extension stage, the middle part of the forefoot region 210 of the second support plate 200 will move away from the human foot bottom, and the front side and the rear side will move towards the human foot bottom, i.e. form a downward protruding one-way bending state, the protrusion of the first reinforcing ribs 240 in the direction of the second surface 231 of the first support plate 230 helps the first reinforcing ribs 240 to extend in the longitudinal direction, so that the forefoot region 210 of the second support plate 200 is easy to deform, if the middle part of the first reinforcing ribs 240 bends towards the human foot, the first reinforcing ribs 240 are pressed in the longitudinal direction, preventing further bending, i.e. the above structure can realize the technical effect that the forefoot region 210 of the second support plate 200 is easy to bend in one direction.

[0044] It can be understood that the number of grooves 212 corresponds to the number of first reinforcing ribs 240, and the grooves 212 are arranged to prevent the overall thickness of the position of the forefoot region 210 of the second support plate 200 corresponding to the first reinforcing ribs 240 from being too large, so that the rigidity of the forefoot region 210 of the second support plate 200 is excessively increased, making it not easy to bend. In the present embodiment, two first reinforcing ribs 240 are arranged, which is a preferred scheme matched with the thickness of the forefoot region 210 of the second support plate 200 in the present embodiment, which can provide appropriate support strength for the forefoot region 210 of the second support plate 200, and more than one will be too rigid to bend, and less than one will not have enough rigidity to support effectively.

[0045] The first reinforcing rib 240 is provided with a plurality of slits 241 in the transverse direction. The slits 241 are provided through the first reinforcing rib 240, and separate the first reinforcing rib 240 in the longitudinal direction. The slits 241 extend the length of the first reinforcing rib 240 in the longitudinal direction, and further reduce the rigidity of the first reinforcing rib 240 in the single bending state. The rigidity of the forefoot region 210 of the second support plate 200 and the first support plate 230 is reduced, and the forefoot region 210 of the second support plate 200 and the first support plate 230 are more easily bent in one direction. The number of slits 241 can be set according to actual needs. In the present embodiment, four slits 241 are provided on each first reinforcing rib 240. This is a preferred solution that is adapted to the thickness of the forefoot region 210 of the second support plate 200 and the thickness of the first reinforcing rib 240. The four slits 241 provide a suitable bending radius for the forefoot region 210 of the second support plate 200 and the first support plate 230. More slits 241 will cause excessive bending, and fewer slits 241 will make the first reinforcing rib 240 too rigid to bend. The four slits 241 are evenly distributed on the position of the human forefoot that is stressed during the extension stage, and provide better bending efficiency.

[0046] The first support plate 230 is made of a ductile material, and the second support plate 200 is made of a hard material. The ductility of the first support plate 230 generates a traction force on the front side and the back side of the forefoot region 210 of the second support plate 200 in the single bending state. The forefoot region 210 of the second support plate 200 is not easily broken, and the forefoot region 210 of the second support plate 200 can quickly recover to the initial shape after single bending. In the present embodiment, the first support plate 230 is made of nylon, and the second support plate 200 is made of carbon fiber. The first support plate 230 can also be made of polyamide, polylactic acid, polybutylene terephthalate, etc.

[0047] Further, the support member is a sheet structure, the direction between the top surface and the bottom surface 211 of the forefoot region 210 of the second support plate 200 is defined as the vertical direction, the length of the vertical direction is defined as the thickness, the thickness of the forefoot region 210 of the second support plate 200 is 0.5mm-1mm, wherein the thickness near the front side of the toes of the human body is 0.8mm, the thickness of the region opposite to the first support plate 230 of the forefoot region 210 of the second support plate 200 is 0.5mm, the thickness of other positions of the forefoot region 210 of the second support plate 200 is 1mm, the thickness of the first reinforcing rib 240 is 3mm-4mm, the distance between the cutout 241 near the front side of the sole body and the cutout 241 near the rear side of the sole body is defined as the width of the cutout 241, and the width of the cutout 241 is 0.8mm-1.5mm. The parameters are combined with the preferred number of reinforcing ribs and the number of cutouts 241 to achieve the technical effect that the forefoot region 210 of the second support plate 200 is easily bent in one direction and is not easily broken, and can quickly recover to the original shape.

[0048] Preferably, two second reinforcing ribs 250 are arranged on the midfoot region 220 of the second support plate 200, and the second reinforcing rib 250 corresponds to the first reinforcing rib 240 on the first support plate 230 one by one, that is, the second reinforcing rib 250 is arranged along the end of the first reinforcing rib 240 near the rear side of the sole body, so that the stress of the first reinforcing rib 240 is linearly transmitted to the midfoot region 220 when the forefoot region 210 of the second support plate 200 is bent in one direction, the risk of breaking of the forefoot region 210 of the second support plate 200 is reduced, the force transmission of the foot bottom in the push-up stage is smoother, and the comfort and stability during exercise are improved.

[0049] The utility model also provides a sole comprising the above support member.

[0050] The utility model also provides a shoe comprising the above sole.

[0051] The support member has the following advantages:

[0052] 1. The first reinforcing rib is arranged on the support member, thereby enhancing the rigidity of the forefoot region of the support member, and at least one cutout is arranged transversely on the first reinforcing rib, the position of the cutout corresponds to the stress position of the forefoot region of the human foot in the push-up stage, thereby reducing the rigidity of the first reinforcing rib in the one-way bending state, and the forefoot region of the support member has high toughness and is easy to bend in one direction.

[0053] 2. Set up a reinforcing component in the forefoot area of ​​the support component or set it as a split structure. Through the traction effect of the reinforcing component or split structure, a traction force is formed on the front and rear sides of the forefoot area of ​​the support component in a unidirectional bending state, so that the forefoot area of ​​the support component is not easy to break. At the same time, it can further enable the forefoot area of ​​the support component to quickly return to its initial shape after unidirectional bending.

[0054] 3. A second reinforcing rib is provided in the midfoot area of ​​the support member. The second reinforcing rib corresponds one-to-one with the first reinforcing rib on the first support plate, so that the force of the first reinforcing rib when it bends unidirectionally in the forefoot area of ​​the support member is linearly transmitted to the midfoot area, making the force transmission of the sole of the foot smoother during the push-off phase and improving the comfort and stability during exercise.
