[0039] In order to better understand the purpose, structure and function of the present invention, the shoe support member of the present invention is described in detail below with reference to the accompanying drawings.

[0040] like Figure 1 As shown, the shoe support has a spoon-shaped structure as a whole, including a forefoot area 100, a midfoot area 200 and a heel area 300 which are connected in sequence. The side of the support body close to the inner side of the human foot is defined as the inner side of the support body, the side of the support body close to the outer side of the human foot is defined as the outer side of the support body, the side of the support body close to the toes is defined as the front side of the support body, and the side of the support body close to the heel is defined as the back side of the support body. The forefoot area 100 is in the shape of a spoon head, corresponding to the forefoot of the human foot, the midfoot area 200 is in the shape of a spoon handle, close to the outer side of the support, corresponding to the outer side of the human arch, and the heel area 300 is in the shape of a spoon tail, close to the outer side of the support, corresponding to the outer side of the sole of the human foot.

[0041] This utility model is based on the concept of digital twins and recruits subjects to learn standing long jump movement skills. The contour and structure of the forefoot area 100 of the support part are designed according to the footprint characteristics of the take-off phase in the capstan posture of the metatarsophalangeal joint. The structure of the heel area 300 of the support part is optimized according to the pressure distribution between the heel and the ground at the moment of landing. While following the technical characteristics of take-off, the mechanical structure is improved to improve the athletic performance, achieve the optimization of the center of mass height, take-off speed and take-off angle in the take-off phase, and take into account the cushioning performance of landing to reduce the risk of injury.

[0042] In order to better understand the purpose, structure and function of the present invention, the following describes the shoe support member, sole and shoe of the present invention in further detail with reference to the accompanying drawings, taking the specific structure of the shoe support member as an example.

[0043] like Figures 1 to 3 As shown, the shoe support includes a forefoot area 100, a midfoot area 200 and a heel area 300. A pressure zone 110 is set on the forefoot area 100. The pressure zone 110 protrudes from the forefoot area 100 and is set downward. The downward setting of the pressure zone 110 makes the top surface of the forefoot area 100 completely contact the sole of the foot, providing better wearing comfort. Of course, it can also be set to protrude upward, as long as the pressure zone 110 can form a convex structure. The pressure zone 110 corresponds to the area where stress of the human body is concentrated during the take-off stage. When a vertical downward force is applied to the pressure zone 110, the winch mechanism of the human foot can be fully utilized, thereby improving the effectiveness of the take-off action.

[0044] Specifically, the capstan mechanism, also known as the hinge mechanism, is an important concept in human foot biomechanics. This mechanism primarily involves the interaction between the plantar fascia and the first and second metatarsophalangeal joints, and is crucial for maintaining foot stability and function. The plantar fascia is a strong ligament connecting the heel and forefoot. It originates from the calcaneal tuberosity and extends forward to the base of the proximal phalanx of each toe. When the first and second metatarsophalangeal joints are dorsiflexed (i.e., lifted upward), the plantar fascia is tightened and generates tension. This tension will further depress the first and second metatarsal bones, increasing the weight under the first and second metatarsal heads. As the first and second metatarsal bones are depressed, the medial longitudinal arch of the foot will be raised, thereby enhancing the stability and support of the foot. This arch-raising effect helps to better distribute the weight during gait and reduce the burden on other parts of the foot. In the winch mechanism, the elastic energy storage and release process of the plantar fascia also involves energy conversion. When the foot contacts the ground and bears the weight, the plantar fascia absorbs and stores energy, and when the foot pushes off the ground, When the foot is pushed off the ground, the stored energy will be released, helping the foot to generate effective propulsion when pushing off the ground. Therefore, the pressure zone 110 is a convex structure, which concentrates the stress of the metatarsophalangeal joint in the forefoot area 100 downward, thereby providing effective support, improving the proprioception of the foot and the ground during take-off, and enhancing the dorsiflexion effect. At the same time, the plantar fascia will be fully tightened and generate tension to store more elastic energy. When the foot is pushed off the ground, the pressure zone can reduce the diffusion of force in the take-off stage, and the elastic energy will be fully released, thereby improving the effectiveness of the take-off action.

[0045] Preferably, the pressure zone 110 corresponds to the first metatarsophalangeal joint and the second metatarsophalangeal joint of the human foot. According to the characteristics of the plantar pressure mark in the capstan posture, such as Figure 8 As shown, the pressure concentration area is drawn based on the horizontal projection of the plantar pressure distribution. It can be seen that the first and second metatarsophalangeal joints are independent of the other metatarsophalangeal joints, and the corresponding pressure area 110 is set to separate the first and second metatarsophalangeal joints from the other metatarsophalangeal joints. By setting the pressure area 110 in the forefoot area 100, stress concentration is achieved, the proprioception of the human body in the heel-lift posture is improved, the sense of pushing off the ground during the take-off phase is improved, and at the same time, the diffusion of force during the take-off phase is reduced, the effectiveness of the take-off action is improved, and the winch ergonomic effect of the first and second metatarsophalangeal joints is achieved.

[0046] Further, according to Figure 8 The horizontal projection of the plantar pressure distribution sets the pressure area 110. The inner and outer widths of the pressure area 110 are greater than the front and rear lengths. The overall structure is a sheet-like convex structure to conform to the shape of the plantar pressure mark. It is composed of four arc segments connected and enclosed by the bottom wall, as shown in FIG. Figure 3As shown, the four arcs are respectively the front side wall 111, the inner side wall 112, the rear side wall 113, and the outer side wall 114, wherein the arc radius of the front side wall 111 is 37mm-47mm, the arc radius of the rear side wall 113 is 24mm-34mm, the arc radius of the inner side wall 112 is 2.2mm-12.2mm, and the arc radius of the outer side wall 114 is 2.2mm-12.2mm. Preferably, the arc radius of the front side wall 111 is 42mm, the arc radius of the rear side wall 113 is 29mm, the arc radius of the inner wall 112 is 7.2mm, and the arc radius of the outer side wall 114 is 7.2mm. According to the above structural parameter setting, the adaptability of the first and second metatarsophalangeal joints to the pressure zone 110 can be improved, so that the first and second metatarsophalangeal joints completely correspond to the pressure zone 110, thereby improving the proprioception of the foot and the ground during take-off and improving the winch efficiency of the first and second metatarsophalangeal joints. At the same time, each connection between the front side wall 111, the inner side wall 112, the rear side wall 113, the outer side wall 114 of the raised structure and the bottom wall is provided with a circular chamfer with a radius of 0.05mm-0.15mm, preferably with a radius of 0.1mm, to ensure wearing comfort.

[0047] Preferably, the wall depth of the raised structure in the pressure zone 110 is set to 0.5mm-1.5mm, which can increase the thickness of the support member in the key stress concentration area, significantly enhance its structural strength and rigidity, and improve the bending resistance of the support member, reducing the risk of deformation. The wall depth is preferably 1mm. If it is greater than 1mm, the thickness will be significantly increased. If it is less than 1mm, the stress distribution optimization effect cannot be fully exerted, the structural strength and power output cannot be significantly improved, and the effectiveness of setting the raised structure is reduced.

[0048] Further, such as Figures 1 to 3 、 Figure 12 As shown, the support member is a spoon-shaped structure, the forefoot area 100 is in the shape of a spoon head, corresponding to the metatarsal bones and phalanges of the human foot, the midfoot area 200 is in the shape of a spoon handle, close to the outside of the support member, corresponding to the outside of the human arch, and the heel area 300 is in the shape of a spoon tail, close to the outside of the support member, corresponding to the outside of the human sole. The above structure is set according to the horizontal projection of the sole pressure at take-off to support the pressure concentration area of ​​the sole, wherein the forefoot area 100 includes an arc-shaped first side 102, a second side 103, a third side 104 and a fourth side 105, which are respectively located on the outside, front, inside and back of the forefoot area.

[0049] Specifically, the arc radius of the first side 102 is 45mm-55mm, the arc radius of the second side 103 is 30mm-40mm, the arc radius of the third side 104 is 27mm-37mm, and the arc radius of the fourth side 105 is 22mm-32mm. The widths of the forefoot region 100 and the heel region 300 are greater than the width of the midfoot region 200. The width of the connection between the forefoot region 100 and the midfoot region 200 is 23mm-33mm, and the width of the connection between the midfoot region 200 and the heel region 300 is 13mm-23mm. Preferably, the arc radius of the first side 102 is 50mm, the arc radius of the second side 103 is 30mm-40mm, the arc radius of the third side 104 is 27mm-37mm, and the arc radius of the fourth side 105 is 22mm-32mm. The arc radius of 03 is 35mm, the arc radius of the third side 104 is 32mm, and the arc radius of the fourth side 105 is 27mm. The widths of the forefoot area 100 and the heel area 300 are greater than the width of the midfoot area 200. The width of the connection between the forefoot area 100 and the midfoot area 200 is 28mm, and the width of the connection between the midfoot area 200 and the heel area 300 is 18mm. The above structural parameters are set based on the horizontal projection of the plantar pressure, while taking into account the connection and transition. The four arc edges are connected by curves to improve the adaptability of the support component to the sole of the foot, enhance the support effect, and improve the wearing comfort.

[0050] Further, such as Figure 3 、 Figure 6 and Figure 7 As shown, the support member can be made of carbon plate material. Since carbon plate material is a carbon fiber reinforced resin composite material, it is mainly composed of fiber material and resin material. Carbon fiber has high specific strength, strong tensile strength, low bending and low elongation. The thickness of the shoe support member is set to 1mm-2mm, preferably 1.5mm, to fully utilize its high elastic modulus and high tensile strength, maximizing the mechanical effect during the take-off phase.

[0051] Furthermore, the center of the forefoot region 100 is concave toward the ground, so that the center of the forefoot region 100 is lower, thereby forming a concave dome structure. The concave dome structure can enhance the geometric rigidity of the forefoot region 100. Figure 4 、 Figure 5 The concave dome structure shown in the figure requires the body to convert chemical energy into mechanical energy through muscle contraction and elastic energy storage during the take-off phase of the standing long jump, thereby generating a forward and upward propulsion force. Therefore, the traditional take-off action requires a knee-bent squat to complete the pre-lengthening and contraction of the muscles. This structure increases the structural rigidity while reducing the force-bearing area, thereby improving the effectiveness of the standing long jump take-off action by reducing the diffusion of force during the take-off phase.

[0052] like Figure 2 、 Figure 4 and Figure 5The vertical distance between the lowest point of the concave dome structure of the forefoot area 100 and the edge of the forefoot area 100 is 2mm-4mm, that is, the height difference between the highest point on the forefoot area 100 and the lowest point on the concave dome structure is 2mm-4mm. Preferably, the height difference is 3mm. This preferred structural parameter setting can maximize the height of the body's center of mass, ensure the accuracy of the take-off action by bending the knees and raising the heels, improve the stiffness of the lower limbs and ensure the pre-stretching of the muscles, thereby improving body stability.

[0053] As shown in Figure 2, the midfoot area 200 arches upward to form an arc structure, and the connecting part between the heel area 300 and the midfoot area 200 is close to the shape of the arch of the foot, so that the midfoot area 200 and the forefoot area 100 are in a front-down and back-up shape. The purpose of setting up this structure is to match the heel-lifting action in the take-off phase, provide support for the midfoot area 200, enable the jumper to maximize the capstan effect of the metatarsophalangeal joint, and effectively optimize the direction of the ground reaction force at the moment of take-off, effectively improve the stability of the lower limbs in the capstan posture, and provide the overall forward force of the sole of the foot at the moment of leaving the ground.

[0054] Furthermore, the angle formed by the intersection of the tangent of the front end point of the midfoot area 200 and the tangent of the rear end point of the forefoot area 100 is 140 degrees to 160 degrees, that is, the arc of the angle between the sagittal plane of the midfoot area 200 and the forefoot area 100 is set to 140 degrees to 160 degrees, preferably 150 degrees. The preferred structural parameters are set based on the optimal take-off angle (an angle of 30 degrees with the ground) of existing standing long jump biomechanics research, and a smooth transition curve is used to connect the forefoot area 100 and the midfoot area 200, so as to ensure comfort when worn while taking into account the optimal take-off angle of the standing long jump action, so that the mechanical effect in the winch posture can be fully exerted.

[0055] Further, such as Figure 3 and Figure 7 As shown, a hollow decompression area is provided in the heel area 300 to improve the embedded coupling effect between the sole and the support member. By matching the decompression area with the stress distribution area when the heel lands, the weight-bearing and safety protection functions of the foot are better realized, the wrapping and stability between the heel bone and the shoe are increased, and the comfort at the landing moment is improved. Figure 9 The pressure level projection of the heel sole is shown, and the decompression area is preferably elliptical, with the front-to-back direction of the support as the long axis of the ellipse, and the long axis of the ellipse is set to 32mm, and the short axis is 18mm. Preferably, the long axis is 27mm-37mm, and the short axis is 13mm-23mm, so as to improve the adaptability of the heel area 300 of the support and the sole of the foot, enhance the coupling effect, and improve the wearing comfort.

[0056] Further, such as Figure 2 、 Figure 3 and Figure 7 As shown, since the angle of contact between the foot and the ground during the landing phase of the standing long jump is not horizontal, a downwardly inclined bend is provided on the rear side of the heel area 300. While providing stress shielding for the jumper at the moment of landing, it also changes the direction of the upward and backward vertical ground reaction force applied to the heel at the moment of landing, which is beneficial for cushioning. That is, the stress at the moment of landing is concentrated on the bend, and the direction of the impact force is optimized by the bend structure, thereby reducing the risk of heel stress fractures. At the same time, the bend cooperates with the decompression zone of the heel area 300 to further enhance the landing cushioning performance. The length of the bend is 3mm-5mm, preferably, the length of the bend is 4mm, and the angle with the sagittal plane is 145 degrees to 165 degrees, preferably 155 degrees. This parameter setting is to improve the adaptability of the heel area 300 of the support member to the sole of the foot, enhance the cushioning effect, and improve the wearing comfort.

[0057] The utility model provides a shoe sole, comprising the above-mentioned shoe support component, wherein the support component is embedded in the center position of the shoe sole.

[0058] The utility model also provides a shoe comprising the above-mentioned sole.

[0059] Reference Figures 10a to 11c , the above-mentioned soles were experimentally verified using simulation analysis. The subjects were tested on the plantar pressure testing system based on the standing long jump technology of the Chinese invention patent "Method for obtaining the optimal standing long jump technical template" with publication number CN110624220B. The test results of take-off and landing were collected as the load conditions in the boundary conditions during the support simulation analysis, and the constraint conditions were set to be fixed above the upper. The simulation results of the take-off stage show that compared with the support without D, the paradigm equivalent stress of the support with C is mainly concentrated at the first and second metatarsophalangeal joints of the support, which is consistent with the Figure 8 The stress concentration on the support component significantly reduces the stress at the contact surface between the forefoot and the shoe, providing a certain degree of protection. Simulation results during the landing phase show that, compared to support D without support, support C significantly reduces the equivalent stress at the contact surface between the heel and the shoe, and the stress is mainly concentrated at the hollow edge of the support component, effectively reducing stress concentration in the heel at the moment of landing. This verifies that the support component can reduce heel stress concentration through stress shielding, thereby achieving a safe and protective function during landing from a standing jump.

[0060] In summary, the shoe support and sole of the present invention are optimized based on the concept of digital twins, combining the take-off characteristics of the Chinese invention patent "Method for Obtaining the Optimal Standing Long Jump Technical Template" with publication number CN110624220B, starting from the characteristics of the metatarsophalangeal joint capstan mechanism, while also providing landing cushioning. The purpose is to improve the mechanical structure, enhance athletic performance, and provide support, efficiency, and competitive performance during the take-off process. The structure of the forefoot area 100 of the support is designed based on the footprint characteristics of the capstan posture, and the athletic performance is improved by improving the mechanical structure while following the technical characteristics of the jumper.

[0061] The present invention takes into account the mechanical characteristics of the take-off phase and the pressure distribution in the footprint. In view of the metatarsophalangeal joint as the stress concentration area in the take-off phase, the forefoot area 100 of the support member is domed downward and a pressure area 110 raised structure is provided under the support member to increase the structural rigidity and reduce the force-bearing area, thereby improving the effectiveness of the take-off phase. The midfoot area 200 adopts a curved upward connection design to enhance the stability of the lower limbs in the take-off phase. It can effectively optimize the direction of the ground reaction force and provide support for the entire sole of the foot at the moment of leaving the ground, especially the forward force. The heel area 300 adopts a hollow treatment to enhance the coupling effect between the heel and the sole, improve the comfort at the moment of landing, and improve the direction of the impact force at the moment of landing through the end bending treatment to enhance the overall protection performance.
