[0042] To make the purpose, technical solutions and advantages of the present utility model clearer, the technical solutions in the present utility model will be clearly described below in conjunction with the accompanying drawings in the present utility model. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0043] In the description of the embodiments of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings.

Therefore, it should not be construed as a limitation to the embodiments of the present utility model. In addition, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present utility model can be understood according to specific situations.

[0045] In the embodiments of the present utility model, unless otherwise clearly specified and defined, the first feature being "on" or "under" the second feature can be that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on" the second feature can be that the first feature is directly above or obliquely above the second feature, or simply means that the first feature has a higher horizontal height than the second feature. The first feature being "under", "beneath" and "under" the second feature can be that the first feature is directly below or obliquely below the second feature, or simply means that the first feature has a lower horizontal height than the second feature.

In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. In addition, without contradiction, those skilled in the art can combine and combine the different embodiments or examples described in this specification and the features of different embodiments or examples.

[0047] In the present utility model, the elastic modulus refers to the proportionality coefficient of stress and strain in direct proportion during the elastic deformation stage of the material.

[0048] As Figures 1 to 4 shown, in the embodiments of the present utility model, a carbon plate structure for a power-assisted shoe is introduced.

[0049] The carbon plate structure is sequentially provided with a forefoot support portion, a connecting portion, and a rearfoot support portion along its front-back direction.

[0050] Among them, the forefoot support portion gradually bulges upward from its two side edges to its middle, forming an elastic structure that can be deformed under pressure, and is used to assist the forefoot in exerting force. When transitioning from the edge of the forefoot support portion to the middle of the forefoot support portion, the angle between the surface of the bulge and the horizontal plane gradually decreases, forming a three-dimensional curved surface with the middle bulging upward, so that the forefoot support portion has a greater elastic modulus than a curved flat plate.

[0051] In addition, the carbon plate structure in the present utility model can be made of composite materials. For example, carbon fiber, aramid fiber, glass fiber, basalt fiber, and so on.

[0052] Furthermore, according to different pressures borne, the thicknesses of the forefoot support portion, the connecting portion, and the rearfoot support portion are correspondingly set to vary between 1 mm and 3 mm.

[0053] In this embodiment, the carbon plate structure is set as three main regions arranged in sequence along the front-back direction, namely the forefoot support portion, the rearfoot support portion, and the connecting portion, and the middle of the forefoot support portion is set to protrude upward from its edge portion, so that the forefoot support portion forms a three-dimensional curved surface, which can provide multi-directional elastic support force to the foot, and thus can meet the complex movement postures of the foot of the wearer in various movements, greatly meeting the needs of the wearer's foot comfort and stable power assistance in various movements.

[0054] On the basis of the above embodiment, in another embodiment of the present utility model, a carbon plate structure for a power-assisted shoe is introduced.

[0055] The height difference between the edge and the middle of the forefoot support portion is between 0 mm and 6 mm, so that the carbon plate structure can be applicable to more types of shoes, leaving enough space for the wearer's feet and improving the comfort of the shoes.

[0056] On the basis of the above embodiment, in another embodiment of the present utility model, a carbon plate structure for a power-assisted shoe is introduced.

[0057] The cross-section of the forefoot support part along the left-right direction is arc-shaped, and the radian of the cross-section corresponds to the position of the cross-section and gradually decreases from front to back. Thus, during the use of the carbon plate structure, the forefoot support part can provide better rebound assistance for the foot. After the forefoot support part undergoes elastic deformation and needs to return to its original state, it will generate a force opposite to the pressure, thereby providing stable rebound assistance for the foot, reducing the stress on the knee and ankle, and playing a certain protective role for the knee and ankle.

[0058] On the basis of the above embodiment, in another embodiment of the present utility model, a carbon plate structure for a power-assisted shoe is introduced.

[0059] In the front-rear direction, the length of the forefoot support part is at least greater than one-fourth of the total length of the carbon plate structure. And, the height of the middle convex part of the forefoot support part protruding in the front-rear direction is the same.

[0060] On the basis of the above embodiment, in another embodiment of the present utility model, a carbon plate structure for a power-assisted shoe is introduced.

[0061] The forefoot support part is provided with a hem, and the hem bends upwards from the front edge of the forefoot support part, for increasing the elastic modulus.

[0062] On the basis of the above embodiment, in another embodiment of the present utility model, a carbon plate structure for a power-assisted shoe is introduced.

[0063] The rearfoot support part gradually bulges upwards from its two side edges to its middle, forming an elastic structure that can be deformed under pressure, for reducing the vibration force received by the rearfoot.

[0064] Further, the two side edges of the connecting part are flush with the two side edges of the forefoot support part and / or the two side edges of the rearfoot support part, and the middle of the connecting part is recessed downwards, so that the carbon plate structure protrudes at both ends and sinks in the middle in the front-rear direction.

[0065] On the basis of the above embodiment, in another embodiment of the present utility model, a carbon plate structure for a power-assisted shoe is introduced.

[0066] In the front-rear direction, the forefoot support part and the rearfoot support part extend obliquely downwards towards both ends relative to the connecting part respectively to form an arch.

[0067] On the other hand, the present utility model also provides a power-assisted shoe, which is used to provide efficient rebound assistance for the feet of the wearer during various sports.

[0068] Specifically, the assisting shoes include a sole and an upper. The carbon plate structure in any of the above embodiments is embedded in the sole. For example, the carbon plate structure is embedded in the sandwich layer of the sole or on the upper surface of the sole. The forefoot support part, the connecting part, and the rearfoot support part undulate in height along the front-back direction of the wearer's foot, providing rebound assistance to the forefoot and the heel respectively.

[0069] In another embodiment, it is set that the forefoot support part, the connecting part, and the rearfoot support part in the carbon plate structure have the same thickness and the thickness is between 1 mm and 3 mm. In this way, not only can it ensure that the carbon plate structure as a whole has the same elastic modulus, but also it can eliminate the complex process of setting different thicknesses in different areas of the carbon plate structure, reduce the manufacturing difficulty of the carbon plate structure, and improve the production efficiency.

[0070] In addition, the present utility model also provides a kinematic report of the subjects wearing the above shoes during sprinting, hurdling, and long jumping. Specifically as follows:

[0071] I. Sprint report

[0072] 1. Analysis process

[0073] 1.1 Kinematic analysis of the start

[0074] Collect the kinematic data of each subject in the first three steps before the start under different shoe-wearing conditions, requiring that the speed difference with or without the carbon plate does not exceed 0.03 s (for the 10-meter middle-distance running), and analyze the changes in each kinematic index to explore the influence of the carbon plate on running technique.

[0075] The kinematic analysis of the start mainly includes two aspects: gait spatio-temporal parameters and joint angles. Among them, the gait spatio-temporal parameters include step length, step width, step frequency, center-of-gravity speed at landing, front-drive distance (the horizontal distance between the center of the body's gravity and the touchdown point), rear-foot push-off time, front-foot push-off time, and flight time (see the appendix Figure 5 ). Among them, a is the front-foot push-off time, b is the rear-foot push-off time, c is the flight time, and d is the front-drive distance.

[0076] For the joint angles, it mainly includes the knee angle when the swinging leg folds, the knee angle when the rear foot pushes off, the knee angle when the front foot pushes off, and the trunk angle when the front foot pushes off (see the appendix Figure 6 ). Among them, a is the knee angle when the swinging leg folds, b is the knee angle when the rear foot pushes off, c is the knee angle when the front foot pushes off, and d is the trunk angle when the front foot pushes off.

[0077] 1.2 Kinematic analysis of the middle-distance running

[0078] For the middle-distance running, the average kinematic parameters of three steps during the 10m middle-distance running of each subject were collected. The collected indicators included step length, step frequency, step speed, acceleration, flight time, ground contact time, trunk angle at takeoff, maximum center of gravity height, and front kick distance. The average value ± standard deviation with and without the carbon plate was calculated, and the relative change percentage of each indicator after adding the carbon plate was calculated.

[0079] 2. Results and Analysis

[0080] 2.1 Kinematic Parameters in the Starting Phase

[0081] 2.2.1 Step1

[0082] The spatio-temporal gait parameters of the first step in the starting phase before and after adding the carbon plate. It can be seen that after adding the carbon plate, the flight time and step length of the first step in the starting phase increased significantly, the front kick distance shortened, the takeoff time of the front and rear feet increased, and the center of gravity speed at landing and step width decreased. (See Appendix Figure 7 )

[0083] After adding the carbon plate, there were only small changes in the trunk angle and knee angle. Considering the standard deviation, the main effect after adding the carbon plate was to reduce the knee angle when the swinging leg folded, saving the time for retracting and swinging the leg. (See Appendix Figure 8 )

[0084] 2.2.2 Step2

[0085] For the second step in the starting phase, after adding the carbon plate, the flight time increased significantly, the ground contact time decreased, the step length increased, and other indicators changed insignificantly. (See Appendix Figure 9 )

[0086] After adding the carbon plate, the knee angle when the swinging leg folded in the second step of the starting phase decreased, the angle of the swinging leg during the backward swing was larger, the position was higher, and the swinging process was more complete; for the trunk angle at takeoff from the ground, the trunk angle increased significantly after adding the carbon plate. (See Appendix Figure 10 )

[0087] 2.2.3 Step3

[0088] After adding the carbon plate, the flight time of the third step in the starting phase increased significantly, the ground contact time decreased, the step length increased, and the step width decreased (See Appendix Figure 11 )

[0089] After adding the carbon plate, the trunk angle of the third step in the starting phase increased significantly, the knee angle when the swinging leg folded decreased, the angle of the swinging leg during the backward swing was larger, the position was higher, and the swinging process was more complete (See Appendix Figure 12 )

[0090] 2.2 Kinematic Parameters in the Middle-distance Running Phase

[0091] After adding the carbon plate, the running speed in the middle distance increased, the forward pushing distance and acceleration increased significantly, and the ground contact time decreased significantly (see Appendix Figure 13 ).

[0092] 3. Result Analysis

[0093] For the starting stage, after adding the carbon plate, the air time and step length of the first three steps increased significantly. The knee angle decreased when the swinging leg folded, and the angle was larger and the position was higher when the swinging leg swung back. The swinging process was more sufficient, and the trunk angle increased when pushing off the ground in the first three steps. Therefore, it can be inferred that the carbon plate shoes will improve the biomechanical spatio-temporal parameters of sprinting.

[0094] For the middle distance running stage, the carbon plate shoes reduced the athlete's ground contact time and increased the athlete's forward pushing distance and acceleration. It can be seen that the carbon plate shoes help the athlete to accelerate in the middle distance running.

[0095] II. Hurdling Report

[0096] 1. Research Content

[0097] The kinematic analysis of hurdling mainly includes the take-off landing stage, take-off leaving the ground, over-the-hurdle stage and landing after hurdling of the last step of the approach run. It mainly analyzes the center of gravity changes and lower limb joint angles in these stages to explore the influence of the carbon plate on the hurdling movement technique (see Appendix Figure 14 , 15 , 16).

[0098] Appendix Figure 14 In it, G1 is the center of gravity height at take-off landing, G2 is the center of gravity height at take-off leaving the ground, Q1 is the forward pushing distance, Q2 is the backward pushing distance, L1 is the air distance, L2 is the take-off distance, and L3 is the landing after hurdling distance. a is the forward inclination angle of the upper body, b is the hip angle, and c is the knee angle.

[0099] Appendix Figure 15 In it, a is the forward inclination angle of the upper body, b is the hip angle, and c is the knee angle.

[0100] Appendix Figure 16 In it, H1 is the vertical distance between the knee and the hip, and H2 is the vertical distance between the knee and the ankle.

[0101] 2. Results

[0102] 2.1 Overall Spatio-Temporal Kinematic Parameters of Hurdling

[0103] After adding the carbon plate, the take-off distance increased significantly (+8.11%), and the landing after hurdling distance and over-the-hurdle air time decreased (see Appendix Figure 17 ).

[0104] 2.2 Kinematic Parameters at the Take-off Landing Stage

[0105] After adding a carbon plate during the takeoff and landing phase, both the forward push distance and speed increase, while the center of gravity height and the knee angle of the takeoff leg decrease (see Appendix Figure 18 ).

[0106] 2.3 Kinematic parameters during the takeoff and leaving the ground phase

[0107] After adding a carbon plate, all indicators during the takeoff and leaving the ground phase increase. Among them, the forward push distance changes significantly (+21.05%). See Appendix Figure 19 .

[0108] 2.4 Kinematic parameters during the hurdle crossing phase

[0109] After adding a carbon plate, the distance between the knee and the hip decreases significantly (-25.00%), indicating that it has an obvious helping effect on increasing the height of the knee joint. The hurdle crossing speed also increases (see Appendix Figure 20 ).

[0110] 2.5 Kinematic parameters during the landing after hurdling phase

[0111] After adding a carbon plate, the hip angle of the supporting leg increases during the landing after hurdling phase, reducing the descent of the center of gravity. The forward push distance shrinks, which helps to maintain the speed and accelerate the next movement (see Appendix Figure 21 ).

[0112] 3. Result analysis

[0113] As can be seen from the results, for the hurdling action, adding a carbon plate can increase the forward push distance and the airborne distance during the takeoff phase. When attacking the hurdle, adding a carbon plate can reduce the distance between the hip and the knee, indicating that the carbon plate can increase the hip abduction amplitude when attacking the hurdle. During the landing after hurdling phase, the carbon plate shoes significantly reduce the forward push distance. Based on the above results, it can be speculated that the carbon plate shoes may be more helpful for active force - generating actions such as takeoff and attacking the hurdle, as well as the transitional actions after landing. The mechanical changes brought by the carbon plate may affect the athlete's force - generating technique, and the athlete may need to adapt to the elastic changes inside the carbon plate shoes to optimize the movements.

[0114] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.

[0115] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
