Description

Technical Field

[0001] The invention relates to the technical field of sole structures, in particular to a sole structure with an embedded component whose position can be adjusted and a footwear product. Background Art

[0002] A footwear product includes an upper and a sole structure. The upper may be formed of suitable materials to accommodate, secure and support the foot on the sole structure. The upper may cooperate with laces, Velcro or other fasteners to adjust the fit of the upper around the foot. A bottom portion of the upper, which is adjacent to the bottom surface of the foot, is attached to the sole structure.

[0003] The sole structure includes different components that are arranged in layers and connected between the ground and the upper. The bottom layer of the sole structure is the outsole of the sole structure, which provides wear resistance and adhesion to the ground, and can be formed of rubber or other suitable materials. The part above the outsole is the midsole of the sole structure, which provides cushioning and rebound for the foot, and is at least partially formed of a polymer foam material, which deforms after the foot applies pressure to it, so as to achieve cushioning for the foot by weakening the reaction force of the ground on the foot. A foot bed can be defined on the upper surface of the midsole, and the contour of the foot bed can be set to be consistent with the contour of the bottom surface of the foot. The sole structure may also include an insole or insole for improving comfort, which is fixedly or detachably attached to the upper surface of the midsole and is located in the shoe cavity defined by the midsole and the upper.

[0004] In the current sole structure, in order to improve the bending rigidity of the sole structure in the longitudinal direction, a flat and rigid plate-like component with longitudinal stiffness is embedded in the sole structure, and the plate-like component can be made of carbon fiber, nylon, TPU or other suitable materials. Usually, in the sole structure with an embedded plate, the embedded plate is embedded and fixed in the midsole of the sole during the molding process of the sole structure, for example, the plate-like component is embedded in the midsole molding process. However, for different user groups, due to differences in foot shapes, or different requirements for the bending rigidity of the sole structure in the longitudinal direction in different usage scenarios, this footwear product with a fixed embedded plate often cannot meet user needs. Summary of the invention

[0023] Technical solution seventeen based on technical solution sixteen: the mask is made of thermoplastic polyurethane elastomer material and is translucent.

[0024] It can be seen from the above description of the present invention that, compared with the prior art, the present invention has the following beneficial effects:

[0025] Technical solution one provides a sole structure with an embedded component with an adjustable position, the sole structure including a sole body, an embedded component and an embedded drive component, the embedded component including a reinforcement, the reinforcement can be placed in the accommodating cavity of the sole body, the reinforcement itself can enhance the longitudinal bending rigidity of the sole body through the reinforcement part, so that when the user wears the footwear product adopting the sole structure, the bending and rebound of the reinforcement can provide better sole rolling performance; and the embedded drive component can also drive the reinforcement to adjust its position along the length direction in the accommodating cavity, so as to flexibly change the bending rigidity of different parts of the sole according to the foot shape or usage scenario requirements of different users to meet the different needs of users.

[0026] Among them, the reinforcement member in the embedded component includes a reinforcement part and a connecting part. The reinforcement part is placed in the accommodating cavity to enhance the longitudinal bending rigidity of the sole body, and the connecting part extends from the opening of the sole body set on the side wall, and is connected to the embedded drive motor through a transmission mechanism. In this way, the embedded drive motor and the transmission mechanism can be set on the outside of the sole body without being embedded in the inside of the sole body. Embedding in the inside of the sole body is likely to cause the sole body to lose the sole performance at the position of the embedded motor. Setting it on the outside of the sole body can not only ensure that the sole performance is not lost, but also facilitate the assembly, maintenance and replacement of the embedded drive assembly; however, setting the embedded drive motor outside the sole body will make it difficult for the embedded drive motor to drive the reinforcement member to adjust its position in the accommodating cavity. Therefore, the technical solution sets the reinforcement member as a structure in which the connecting part can extend from the opening of the sole body. After the connecting part is extended, it can form a transmission connection with the embedded drive motor through the transmission mechanism outside the sole body; at the same time, setting the transmission mechanism outside the sole body can also avoid the problem of failure and damage caused by friction between the transmission mechanism and the inner wall of the sole body when the transmission mechanism is working.

[0027] In technical solution two, the provision of two reinforcements further improves the uniformity and stability of the overall longitudinal bending rigidity of the sole, and can better adapt to the stress conditions in different areas of the sole; and, since the two reinforcements are independently controlled by a set of embedded drive motors and transmission mechanisms, the positions of the two reinforcements relative to the sole body in the length direction can be adjusted separately according to actual needs, and the rigidity of different positions of the sole can be adjusted more accurately, thereby meeting more complex usage requirements.

[0028] In technical solution three, the reinforcement part of the reinforcement is designed to be a structure of multiple extension arms arranged at intervals. Compared with the reinforcement of the full-palm structure, the structure of the reinforcement in this technical solution can make the enhancement of the longitudinal bending rigidity of the sole structure within an appropriate range, reducing the discomfort caused by the difficulty of bending the sole when the user wears it, and can reduce the contact area with the wall of the accommodating cavity, reduce the friction with the wall of the accommodating cavity, and ensure that the position change can be completed smoothly in the accommodating cavity.

[0029] In technical solution four, the reinforcement part of the reinforcement member includes a first extension arm and a second extension arm. The straight line design of the first extension arm close to the outside mainly enhances the longitudinal rigidity of the outside of the sole, and can effectively resist the bending and deformation of the outside of the sole when walking or exercising. The inclined section of the second extension arm and the second reinforcement section are combined. The special design of the inclined section forms a specific structure in the width direction to optimize the overall performance, and the longitudinal rigidity of the sole close to the midline is enhanced through the second reinforcement section, so that when the sole is under stress, especially near the arch, it can better maintain structural stability and improve comfort and sports performance.

[0030] In Technical Solution 5, the second extension arms of the two reinforcements are staggered in the width direction. By utilizing the synergistic effect of the two reinforcements, the two reinforcements can provide greater longitudinal bending rigidity for the sole at the midline position in the width direction, thereby reducing the impact of the decrease in longitudinal bending rigidity caused by the reinforcement portion of the reinforcement being designed as an extension arm structure on the overall wear and use of the sole; at the same time, when the sole structure is subjected to forces in different directions, the two staggered second extension arms can also restrain and support each other, further improving the stability and torsion resistance of the overall structure of the sole, effectively preventing the sole from excessive deformation under lateral or torsional forces, and improving the reliability of the sole in complex sports scenarios.

[0031] In technical solution six, the inclined section of the second extension arm of the reinforcement extends obliquely from top to bottom in the thickness direction, and the inclination angles of the two inclined sections relative to the horizontal plane are inconsistent, so that the second extension arm of one reinforcement passes over the second extension arm of the other reinforcement and overlaps, so that the two second extension arms form a three-dimensional staggered structure, ensuring that the two will not interfere with each other when the positions are adjusted separately; at the same time, the structure of the inclined extension of the inclined section in the reinforcement part in the thickness direction also makes the reinforcement have further bending changes in the thickness direction. When the forefoot part of the sole structure is bent, it can better fit the bending curve of the metatarsal position of the foot, thereby improving the wearing comfort and providing all-round stable support for the user's foot.

[0032] In Technical Solution 7, the design of uniform thickness and partially flush structure ensures the installation stability and consistency of the reinforcement in the sole accommodating cavity. When subjected to force, the force can be evenly distributed on the entire reinforcement, avoiding local uneven force and stress concentration problems caused by uneven thickness or uneven structure, thereby extending the service life of the reinforcement and the sole structure, and also helps to improve the stability and predictability of the overall performance of the sole.

[0033] In Technical Solution Eight, the setting of the first limiting portion and the second limiting portion accurately limits the position of the reinforcement in the accommodating cavity, ensuring that the different extension arms of the reinforcement will not loosen when adjusting their positions in the accommodating cavity, and preventing unnecessary displacement during use; at the same time, the adaptive cavity wall distance design enables the reinforcement to remain stable in the accommodating cavity and to make slight adjustments within the allowable range when subjected to a certain external force, thereby ensuring a close fit between the reinforcement and the sole body and improving the overall reliability and performance stability of the sole structure.

[0034] In the ninth technical solution, the presence of the reinforcement effectively enhances the structural strength of the opening and reduces the problem of weak sole structure caused by the opening. During the process of extending and adjusting the position of the reinforcement connection, the reinforcement can bear part of the stress and prevent the opening from being excessively deformed or damaged due to the force, thereby protecting the integrity of the overall structure of the sole, ensuring the normal operation of the embedded drive assembly, and also helping to extend the service life of the sole.

[0035] In Technical Solution 10, through the cooperation of the limit tube and the sliding part, the linear reciprocating motion of the motor can be stably transmitted to the connecting part of the reinforcement, thereby realizing the precise position adjustment of the reinforcement in the accommodating cavity; the limit tube plays a guiding and limiting role on the sliding part, ensuring the accuracy of the moving direction of the reinforcement, reducing deviations and jams during movement, improving the reliability and stability of the drive system, and thus realizing precise control of the rigidity of the sole.

[0036] In Technical Solution XI, the screw connection transmission of the lead screw and the threaded part is utilized to convert the rotational motion of the motor into the linear motion of the threaded part, which has the advantages of high transmission accuracy and large transmission ratio; it can more finely control the position adjustment of the reinforcement and achieve fine-tuning of the longitudinal bending rigidity of the sole, meeting the usage scenarios with high requirements on the performance of the sole; at the same time, the lead screw transmission structure is compact and occupies relatively small space, which is conducive to the arrangement of the drive components in the limited space of the sole, and has high transmission efficiency, which can reduce the energy consumption of the motor.

[0037] In Technical Solution XII, the reinforcement is made of carbon fiber, nylon or thermoplastic polyurethane elastomer; carbon fiber has the characteristics of high strength, high rigidity and low density, which can greatly improve the longitudinal bending rigidity of the sole without increasing too much weight of the sole, and provide excellent support performance; nylon has good wear resistance, toughness and certain rigidity, which can make the reinforcement have certain impact resistance while enhancing the rigidity of the sole, thereby extending the service life of the sole; thermoplastic polyurethane elastomer has both elasticity and rigidity, which can not only effectively enhance the rigidity of the sole, but also maintain the flexibility and comfort of the sole to a certain extent, and adapt to different movement states and foot movements.

[0038] In the technical solution 13, the reinforcement is made of nylon or thermoplastic polyurethane elastomer. The reinforcement made of nylon can provide high strength and wear resistance, effectively resist the wear and deformation caused by the force on the opening, and protect the sole structure; the reinforcement made of thermoplastic polyurethane elastomer has good elasticity and flexibility while providing a certain strength. It can match the elastic characteristics of the sole body while enhancing the strength of the opening structure, avoiding the influence of the comfort and flexibility of the sole as a whole due to the reinforcement being too hard.

[0039] Technical solution fourteen provides a footwear product, which, based on the above-mentioned sole structure, also includes an upper structure and a shoelace drive assembly. The upper structure is combined with the sole structure to form a complete footwear product. The addition of the shoelace drive assembly realizes the automatic tightening or loosening function of the shoelaces; the user does not need to tie the shoelaces manually, which is convenient and quick, and improves the convenience of putting on and taking off shoes; at the same time, the tightness of the shoelaces can be adjusted at any time according to different wearing needs, providing a more comfortable fit, thereby improving the overall comfort and functionality of the footwear product.

[0040] Technical Solution 15 also includes a control component, the battery of which provides power to the embedded drive motor and the shoelace drive motor, so that the position adjustment of the sole reinforcement and the automatic tightening of the shoelaces can be realized. The setting of the switch is convenient for the user to control the operation of the motor, and the operation is simple and easy to use. The battery is located at the rear end of the upper, which makes reasonable use of the upper space and does not affect the overall appearance and wearing comfort of the shoe.

[0041] In the technical solution 16, the shield protects the internal components, preventing the embedded drive components, shoelace drive components and control components from being affected by external collisions, water splashes or dust, thereby extending the service life of these components and ensuring their normal operation. The semi-enclosed design not only achieves effective protection, but also does not have too much impact on the overall appearance and wearing comfort of the shoes. At the same time, it can also enhance the overall aesthetics and sense of technology of the footwear products to a certain extent.

[0042] In the technical solution 17, the thermoplastic polyurethane elastomer material makes the mask have good flexibility and wear resistance, can adapt to various deformations and frictions of shoes during wearing, and is not easy to be damaged. The translucent property allows users to observe the working status of internal components to a certain extent, which increases the visibility and interest of the product. At the same time, it is also convenient for users to promptly discover potential problems during use, such as whether there is abnormal displacement of components, etc., which is convenient for timely maintenance and processing.

[0055] In the claims, description and drawings of the present invention, if the terms "include", "have" and their variations are used, they are intended to mean "including but not limited to".

[0056] The embodiment of the present invention relates to a footwear product, referring to Figure 1 and Figure 2 The footwear product includes an upper structure, a shoelace 21 driving component, a control component 23, a mask 24 and a sole structure with an embedded component with an adjustable position.

[0057] First, the sole structure with the embedded component whose position can be adjusted is described.

[0058] The sole structure comprises: a sole body 1, which is provided with a flat accommodating cavity 2 extending in the length direction and the width direction at the middle position in the thickness direction; the accommodating cavity 2 is located at the forefoot part and the arch part of the sole body 1, and an opening 3 extending in the length direction and communicating with the outside of the sole body 1 is provided on the side wall of the arch part; an embedded component 4, which comprises a reinforcing member 5 placed in the accommodating cavity 2, the reinforcing member 5 is limited by the upper side cavity wall and the lower side cavity wall in the thickness direction of the accommodating cavity 2, and is provided with a reinforcing portion 6 and a connecting portion 7; the reinforcing portion 6 is provided in the length direction Extending and placed in the accommodating cavity 2 to enhance the longitudinal bending rigidity of the sole body 1, the connecting portion 7 extends out of the opening 3; and an embedded driving assembly 8, which includes an embedded driving motor 9 and a transmission mechanism 10; the embedded driving motor 9 is installed on the side wall of the heel portion of the sole body 1; the transmission mechanism 10 is transmission-connected to the output end of the embedded driving motor 9, and its output end is connected to the connecting portion 7 of the reinforcement 5, so as to drive the reinforcement 5 to adjust its position in the accommodating cavity 2 along the length direction when the embedded driving motor 9 is running.

[0059] Among them, the embedded component 4 includes two reinforcements 5 arranged along the width direction; the sole body 1 is provided with the opening 3 on both sides of its width direction, and the connecting part 7 of the reinforcement 5 located on the same side as the opening 3 extends out of the opening 3; the embedded drive component 8 is provided with a group of embedded drive motors 9 and transmission mechanisms 10 with transmission connections on both sides of the width direction of the sole body 1, and the connecting part 7 of the reinforcement 5 located on the same side of the group of embedded drive motors 9 and transmission mechanisms 10 is connected to the output end of the transmission mechanism 10.

[0060] Specifically, refer to Figure 1 and Figure 2 The sole body 1 in the sole structure includes an outsole and a midsole. The outsole is attached to the midsole by hot melting, hot pressing, gluing, etc. The midsole has a certain thickness and is used to provide rebound and shock absorption performance for users. The materials of the outsole and the midsole can be selected according to actual needs, and will not be described in detail here.

[0061] Reference Figure 4 , a accommodating cavity 2 is provided in the sole body 1, and the accommodating cavity 2 is a flat cavity structure extending in the length direction and the width direction, and its distribution range is located at the forefoot part and the arch part of the sole body 1. For a conventional sole structure, it can be divided into the forefoot part, the arch part and the heel part according to the corresponding relationship with the foot. There is no strict dividing line between these parts, but it is enough for a person skilled in the art to clearly distinguish the differences between the various parts on the surface. In addition, since the outer contour of the sole body 1 is adapted to the outer contour of the bottom surface of the foot, the width of the sole body 1 presents a trend of increasing, decreasing and then increasing from front to back, with the front end width of the forefoot part being smaller, the width of the middle part of the forefoot part being the largest, the width of the arch part being reduced again, and then slightly increasing at the heel part.

[0062] The opening 3 on the sole body 1 is mainly arranged at the arch of the foot. Figure 1 The opening 3 is also partially located at the forefoot and heel, which is related to the range of movement of the reinforcement 5 in the embedded component 4 in the accommodating cavity 2. The opening 3 on the sole body 1 is flat to expose the accommodating cavity 2 in the sole body 1 less.

[0063] The accommodating cavity 2 can be formed in the sole body 1 by dividing the midsole of the sole body 1 into two upper and lower parts, respectively forming a part of the accommodating cavity 2, and then merging the two parts into an integral midsole. Alternatively, a placeholder mold can be arranged at the position of the accommodating cavity 2, and the midsole can be directly formed by foaming, and the placeholder mold can be pulled out from the opening 3 provided on the sole body 1 after the midsole is formed.

[0064] Reference Figure 3The embedded component 4 includes two reinforcement members 5, which are arranged in the accommodating cavity 2 along the width direction. At the same time, both sides of the width direction of the sole body 1 are also provided with openings 3, and the connecting portion 7 of the reinforcement member 5 can extend from the corresponding openings 3 to the outside of the sole body 1. The reinforcement portion 6 of the reinforcement member 5 is always in the accommodating cavity 2, which plays a role in enhancing the longitudinal bending rigidity of the sole body 1. Through the limiting effect of the accommodating cavity 2 on the reinforcement member 5, the reinforcement member 5 can adjust the position in the accommodating cavity 2 along the length direction, so as to accurately control the longitudinal bending strength of the sole structure at different parts. The setting of the two reinforcement members 5 further improves the uniformity and stability of the overall longitudinal bending rigidity of the sole, and can better adapt to the stress conditions in different areas of the sole.

[0065] The embedded drive assembly 8 includes two groups of embedded drive motors 9 and transmission mechanisms 10, one embedded drive motor 9 and one correspondingly connected transmission mechanism 10 are a group. Among them, the embedded drive motor 9 is bonded and fixed on the side wall of the heel part of the sole body 1. At its installation position, the side wall of the sole body 1 can be slightly concave to form a groove structure for accommodating the embedded drive motor 9, reducing the protrusion of the embedded drive motor 9. In addition, the output end of the embedded drive motor 9 has two different output modes, one is that its output end can extend and retract along the length direction, for example, the embedded drive motor 9 adopts an electric cylinder; the other is that its output end can rotate around the axis along the length direction, for example, the embedded drive motor 9 adopts a DC motor. It is easy to understand that, since in the present invention, the embedded drive motor 9 is arranged on the side wall of the heel part of the sole body 1, there is obviously not enough space in the width direction for the embedded drive motor 9 to install. Therefore, the installation direction of the embedded drive motor 9 is to make its length direction consistent with the length direction of the sole body 1, and its output end is all towards the front end of the sole body 1.

[0066] The transmission mechanism 10 is arranged before the embedded drive motor 9 and is connected to the output end of the embedded drive motor 9. The transmission mechanism 10 can transmit the movement of the output end of the embedded drive motor 9 to the reinforcement part 6 through the connection between the output end and the connection part 7 of the reinforcement part 5, so that the reinforcement part 6 is driven to adjust the position in the accommodating cavity 2. In addition, since two sets of embedded drive motors 9 and transmission mechanisms 10 are provided, and one of the reinforcement parts 5 is controlled respectively, the positions of the two reinforcement parts 5 relative to the sole body 1 in the length direction can be adjusted respectively according to actual needs, and the rigidity of different positions of the sole can be adjusted more accurately, so as to meet more complex use requirements.

[0067] In the sole structure with an embedded component with adjustable position, the reinforcement 5 itself can enhance the longitudinal bending rigidity of the sole body 1 through the reinforcement part 6, so that when the user wears the footwear product with this sole structure, the bending and rebound of the reinforcement 5 can provide better sole rolling performance; and the embedded driving component 8 can also drive the reinforcement 5 to adjust its position along the length direction in the accommodating cavity 2, so as to flexibly change the bending rigidity of different parts of the sole according to the foot shape or usage scenario requirements of different users to meet the different needs of users. Among them, the reinforcement member 5 in the embedded component 4 includes a reinforcement part 6 and a connecting part 7. The reinforcement part 6 is placed in the accommodating cavity 2 to enhance the longitudinal bending rigidity of the sole body 1, and the connecting part 7 extends from the opening 3 set on the side wall of the sole body 1, and is connected to the embedded driving motor 9 through the transmission mechanism 10. In this way, the embedded driving motor 9 and the transmission mechanism 10 can be set on the outside of the sole body 1 without being embedded in the inside of the sole body 1. Embedding in the inside of the sole body 1 is likely to cause the sole body 1 to lose the sole performance at the position where the motor is embedded. Setting it on the outside of the sole body 1 can not only ensure that the sole performance is not lost, but also It can facilitate the assembly, maintenance and replacement of the embedded drive component 8; however, setting the embedded drive motor 9 outside the sole body 1 will make it difficult for the embedded drive motor 9 to drive the reinforcement 5 to adjust its position in the accommodating cavity 2. Therefore, the technical solution arranges the reinforcement 5 as a structure in which the connecting part 7 can extend from the opening 3 of the sole body 1. After the connecting part 7 is extended, a transmission connection can be formed with the embedded drive motor 9 through the transmission mechanism 10 on the outside of the sole body 1; at the same time, setting the transmission mechanism 10 on the outside of the sole body 1 can also avoid the problem of failure or damage caused by friction between the transmission mechanism 10 and the internal wall of the sole body 1 when the transmission mechanism 10 is working.

[0068] As one aspect of the sole structure involved in this embodiment, the structure of the reinforcement 5 is further described below.

[0069] Reference Figure 3 and Figure 4 The reinforcing portion 6 of the reinforcing member 5 includes a plurality of extension arms arranged at intervals in the width direction and extending in the length direction, and the lower end of each of the extension arms is connected to the connecting portion 7. The reinforcing portion 6 of the reinforcing member 5 includes a first extension arm 11 and a second extension arm 12; the first extension arm 11 is close to the outer side of the sole body 1 in the width direction, and extends straightly in the length direction to form a first reinforcing section 13; the second extension arm 12 is close to the midline in the width direction of the sole body 1, and its portion close to the connecting portion 7 extends obliquely from the outer side of the sole body 1 toward the midline in the width direction to form an inclined section 14, and its portion relatively far from the connecting portion 7 extends straightly in the length direction to form a second reinforcing section 15.

[0070] The inclined sections 14 of the second extension arms 12 of the two reinforcement members 5 overlap in the thickness direction, so that the two reinforcement members 5 are staggered in the width direction. The inclined sections 14 of the second extension arms 12 of the reinforcement members 5 extend obliquely from top to bottom in the thickness direction, and the inclined angles of the inclined sections 14 of the second extension arms 12 of the two reinforcement members 5 relative to the horizontal plane are inconsistent, so that the second extension arm 12 of one reinforcement member 5 passes over the second extension arm 12 of the other reinforcement member 5 in the thickness direction and overlaps in the thickness direction. The thickness of the reinforcement members 5 is uniformly set, and the first extension arms 11 and the connecting parts 7 of the two reinforcement members 5 are flush in the thickness direction, and the second reinforcement sections 15 of the second extension arms 12 of the two reinforcement members 5 are flush in the thickness direction.

[0071] Specifically, refer to Figure 3 The reinforcement member 5 includes a reinforcement portion 6 and a connection portion 7, wherein the connection portion 7 extends from the opening 3 provided on the sole body 1 to the outside of the sole body 1, and is connected to the transmission mechanism 10 embedded in the driving assembly 8 to drive the reinforcement member 5 to adjust its position in the accommodating cavity 2. The reinforcement portion 6 and the connection portion 7 are integrally formed, and include two extension arms extending along the length direction, namely, a first extension arm 11 close to the outside of the sole body 1, and a second extension arm 12 close to the midline of the width direction of the sole body 1. In short, the position of the first extension arm 11 is closer to the outside of the sole body 1 than the second extension arm 12. A gap is formed between the first extension arm 11 and the second extension arm 12, so that the reinforcement member 5 forms a knife-and-fork-shaped structure. The reinforcement portion 6 of the reinforcement 5 is designed to be a structure of multiple extension arms arranged at intervals. Compared with the reinforcement 5 of the full-palm structure, the structure of the reinforcement 5 in the present technical solution can make the enhancement of the longitudinal bending rigidity of the sole structure within an appropriate range, thereby reducing the discomfort caused by the difficulty in bending the sole when the user wears the shoe, and can reduce the contact area with the cavity wall of the accommodating cavity 2, reduce the friction with the cavity wall of the accommodating cavity 2, and ensure that the position change in the accommodating cavity 2 can be completed smoothly.

[0072] The first extension arm 11 extends straight forward from the connection position with the connection part 7, thereby forming a first reinforcement section 13. Of course, in actual application, the width of the first extension arm 11 is not fixed, but gradually decreases from the back to the front to increase the connection strength between the first extension arm 11 and the connection part 7. The straight line design of the first extension arm 11 near the outside mainly enhances the longitudinal rigidity of the outside of the sole, and can effectively resist the bending and deformation of the outside of the sole when walking or exercising.

[0073] Since the second extension arm 12 needs to extend out of the opening 3 and the connecting portion 7 is located in an inner position, the second extension arm 12 is provided with an inclined section 14 and a second reinforcement section 15. The inclined section 14 extends obliquely from the inside to the outside and from the front to the back, so that the second reinforcement section 15 and the connecting portion 7 are connected as a whole. The second reinforcement section 15 generally extends straightly from the inclined section 14 to the front. Of course, in practical applications, the width of the second extension arm 12 also presents a structure that gradually decreases from the back to the front to increase the connection strength between the second extension arm 12 and the connecting portion 7. The combination of the inclined section 14 and the second reinforcement section 15 of the second extension arm 12 not only forms a specific structure in the width direction through the special design of the inclined section 14 to optimize the overall performance, but also enhances the longitudinal rigidity of the sole near the midline through the second reinforcement section 15, so that the sole can better maintain structural stability when subjected to force, especially near the arch of the foot, and improve comfort and sports performance.

[0074] Further, refer to Figure 3 and Figure 4 , the inclined sections 14 of the two second extension arms 12 also extend obliquely from top to bottom and from back to front in the thickness direction, and the inclination angles of the two inclined sections 14 relative to the horizontal plane are inconsistent, so that the second extension arms 12 of the two reinforcement members 5 overlap at the position of the inclined sections 14. Specifically, the inclined section 14 of the second extension arm 12 located at the top has a smaller inclination angle relative to the horizontal plane, that is, the slope of the inclined section 14 is gentler, while the slope of the inclined section 14 of the other second extension arm 12 is steeper, which makes it possible for the two inclined sections 14 to stagger with each other without interference when the two reinforcement members 5 are at the same position in the length direction. At the same time, the two second reinforcement sections 15 before the inclined section 14 extend straight, and the two second reinforcement sections 15 can be flush in the thickness direction.

[0075] The second extension arms 12 of the two reinforcements 5 are staggered in the width direction. By utilizing the synergistic effect of the two reinforcements 5, the two reinforcements 5 can provide greater longitudinal bending rigidity for the sole at the midline position in the width direction, thereby reducing the impact of the decrease in longitudinal bending rigidity caused by the reinforcement portion 6 of the reinforcement 5 being designed as an extension arm structure on the overall wear and use of the sole; at the same time, when the sole structure is subjected to forces in different directions, the two staggered second extension arms 12 can also restrain and support each other, further improving the stability and torsion resistance of the overall structure of the sole, effectively preventing the sole from excessive deformation under lateral or torsional forces, and improving the reliability of the sole in complex sports scenarios. The inclined section 14 of the second extension arm 12 of the reinforcement 5 extends obliquely from top to bottom in the thickness direction, and the inclination angles of the two inclined sections 14 relative to the horizontal plane are inconsistent, so that the second extension arm 12 of one reinforcement 5 passes over the second extension arm 12 of the other reinforcement 5 and overlaps, so that the two second extension arms 12 form a three-dimensional staggered structure, ensuring that the two will not interfere with each other when the positions are adjusted separately; at the same time, the structure of the inclined extension of the inclined section 14 in the reinforcement part 6 in the thickness direction also makes the reinforcement 5 have further bending changes in the thickness direction. When bending at the forefoot part of the sole structure, it can better fit the bending curve of the metatarsal position of the foot, thereby improving the wearing comfort and providing all-round stable support for the user's foot.

[0076] The design of uniform thickness and partially flush structure ensures the installation stability and consistency of the reinforcement 5 in the sole accommodating cavity 2. When subjected to force, the force can be evenly distributed on the entire reinforcement 5, avoiding local uneven force and stress concentration problems caused by uneven thickness or uneven structure, thereby extending the service life of the reinforcement 5 and the sole structure, and also helps to improve the stability and predictability of the overall performance of the sole.

[0077] In addition, the reinforcement 5 can be made of carbon fiber, nylon or thermoplastic polyurethane elastomer; carbon fiber has the characteristics of high strength, high rigidity and low density, which can greatly improve the longitudinal bending rigidity of the sole without increasing the weight of the sole, and provide excellent support performance; nylon has good wear resistance, toughness and certain rigidity, which can make the reinforcement 5 have certain impact resistance while enhancing the rigidity of the sole, and extend the service life of the sole; thermoplastic polyurethane elastomer has both elasticity and rigidity, which can effectively enhance the rigidity of the sole, and maintain the flexibility and comfort of the sole to a certain extent, and adapt to different sports states and foot movements. In this embodiment, the reinforcement 5 is preferably made of carbon fiber.

[0078] Reference Figure 4The accommodating cavity 2 is provided with a first limiting portion 16 at a position corresponding to the first extension arms 11 of the two reinforcement members 5, and a second limiting portion 17 at a position corresponding to the second extension arms 12 of the two reinforcement members 5, and the distance between the upper cavity wall and the lower cavity wall of the first limiting portion 16 is adapted to the thickness of the reinforcement member 5, and the distance between the upper cavity wall and the lower cavity wall of the second limiting portion 17 is adapted to the dimension of the reinforcement member 5 in the thickness direction defined by the second reinforcement section 15 of the second extension arm 12 and the first extension arm 11.

[0079] Specifically, the accommodating chamber 2 has different thicknesses in the first limiting portion 16 and the second limiting portion 17, and the thicknesses are defined by the upper and lower cavity walls of the accommodating chamber 2. The first limiting portion 16 is located on both sides of the accommodating chamber 2 in the width direction, corresponding to the first extension arms 11 of the two reinforcement members 5, and the second limiting portion 17 is located in the middle of the accommodating chamber 2 in the width direction, corresponding to the second extension arms 12 of the two reinforcement members 5. Since the inclined section 14 of the second extension arm 12 extends obliquely in the thickness direction, the portion where the second extension arm 12 is connected to the connecting portion 7 and the portion where the second reinforcement section 15 of the second extension arm 12 is connected has a height difference in the thickness direction, thereby defining the size of the second extension arm 12 in the thickness direction, and the thickness of the second limiting portion 17 is roughly consistent with the size of the second extension arm 12 in the thickness direction. The setting of the first limiting portion 16 and the second limiting portion 17 accurately limits the position of the reinforcement 5 in the accommodating cavity 2, ensuring that the different extension arms of the reinforcement 5 will not loosen when adjusting their positions in the accommodating cavity 2, and preventing unnecessary displacement during use; at the same time, the adaptive cavity wall distance design enables the reinforcement 5 to remain stable in the accommodating cavity 2 and to make slight adjustments within the allowable range when subjected to a certain external force, thereby ensuring a close fit between the reinforcement 5 and the sole body 1 and improving the overall reliability and performance stability of the sole structure.

[0080] In addition, a reinforcing member 18 is also provided on the sole body 1, and the reinforcing member 18 is fixedly provided at the opening 3 of the sole body 1 and surrounds the opening 3 to reduce deformation of the opening 3. Figure 1 and Figure 2The reinforcing member 18 is an elliptical flat annular member, which can be attached to the side wall of the sole body 1, and the part surrounded by the inner ring can just fit the range of the opening 3 on the sole body 1, so that the opening 3 of the sole body 1 maintains a fixed shape. The existence of the reinforcing member 18 effectively enhances the structural strength of the opening 3 and reduces the problem of weak sole structure caused by the existence of the opening 3. During the process of extending and adjusting the position of the connecting portion 7 of the reinforcing member 5, the reinforcing member 18 can withstand part of the stress to prevent the opening 3 from being excessively deformed or damaged due to the force, thereby protecting the integrity of the overall structure of the sole, ensuring the normal operation of the embedded drive assembly 8, and also helping to extend the service life of the sole. The reinforcing member 18 is made of nylon or thermoplastic polyurethane elastomer. The reinforcement 18 made of nylon material can provide higher strength and wear resistance, effectively resist the wear and deformation caused by the force on the opening 3, and protect the sole structure; the reinforcement 18 made of thermoplastic polyurethane elastomer material not only provides a certain strength, but also has good elasticity and flexibility. It can enhance the structural strength of the opening 3 while matching the elastic characteristics of the sole body 1, avoiding the reinforcement 18 being too hard and affecting the overall comfort and flexibility of the sole.

[0081] As an embodiment of the embedded drive assembly 8, in the embedded drive assembly 8, the output end of the embedded drive motor 9 is suitable for reciprocating along the length direction; the transmission mechanism 10 includes a limit tube fixedly arranged on the sole body 1 and extending along the length direction and a sliding member located in the limit tube; the sliding member is connected to the output end of the embedded drive motor 9, and is connected to the connecting portion 7 of the reinforcement 5 as the output end of the transmission mechanism 10. Specifically, the limit tube is a tubular member extending along the length direction, which can be fixedly installed on the sole body 1, and a through groove can be set on the side facing the sole body 1, the sliding member is slidably installed in the limit tube, and a connecting arm extending from the through groove can be set on the sliding member, and the thickness of the connecting arm can be adapted to the groove width of the through groove, so that the sliding member will not shake in the limit tube. The connecting arm can be connected to the connecting portion 7 of the reinforcement 5, and the connection method can be bonding, hot melting, etc. The end of the sliding member facing the embedded drive motor 9 can be connected to the output end of the embedded drive motor 9. The embedded drive motor 9 used here can be an electric cylinder, and its output end can reciprocate along the length direction, thereby driving the sliding member to reciprocate along the length direction, and then driving the reinforcement member 5 to reciprocate along the length direction. Through the cooperation of the limit tube and the sliding member, the linear reciprocating motion of the motor can be stably transmitted to the connection part 7 of the reinforcement member 5, thereby realizing the precise position adjustment of the reinforcement member 5 in the accommodating cavity 2; the limit tube plays a guiding and limiting role on the sliding member, ensuring the accuracy of the moving direction of the reinforcement member 5, reducing deviations and jams during the movement process, improving the reliability and stability of the drive system, and then realizing precise regulation of the rigidity of the sole.

[0082] Alternatively, as another embodiment of the embedded drive assembly 8, in the embedded drive assembly 8, the output end of the embedded drive motor 9 is suitable for reciprocating around the axis in the length direction; the transmission mechanism 10 includes a screw rod that is rotatably mounted on the sole body 1 and extends along the length direction around the axis in the length direction and a threaded member that is threadedly connected to the screw rod; the screw rod is connected to the output end of the embedded drive motor 9 and is suitable for receiving the torque, and the threaded member is connected to the connecting portion 7 of the reinforcement 5 as the output end of the transmission mechanism 10. Specifically, the two ends of the screw rod can be rotatably mounted on the sole body 1, for example, a bearing is embedded in the sole body 1, and the two ends of the screw rod are fixed to the inner ring of the bearing, and at the same time, one end of the screw rod facing the embedded drive motor 9 is connected to the output end of the embedded drive motor 9, and the embedded drive motor 9 used here can be a DC motor, and its output end rotates to output torque, thereby driving the screw rod to rotate. A threaded member is threadedly connected to the screw rod, and the threaded member is connected to the connecting portion 7 of the reinforcement 5. When the lead screw is driven by the embedded drive motor 9 to rotate, since the reinforcement member 5 is arranged in the accommodating chamber 2, the reinforcement member 5 plays a role in limiting the threaded member, so that the threaded member will not rotate with the lead screw, but will move along the length direction under the rotation of the lead screw, thereby driving the reinforcement member 5 to adjust its position in the accommodating chamber 2. The screw connection transmission of the lead screw and the threaded member is used to convert the rotational motion of the motor into the linear motion of the threaded member, which has the advantages of high transmission accuracy and large transmission ratio; the position adjustment of the reinforcement member 5 can be more finely controlled to achieve fine adjustment of the longitudinal bending rigidity of the sole, meeting the use scenarios with high requirements for the performance of the sole; at the same time, the lead screw transmission structure is compact and occupies relatively small space, which is conducive to arranging the drive components in the limited space of the sole, and the transmission efficiency is high, which can reduce the energy consumption of the motor.

[0083] As another aspect of the footwear product involved in the embodiment of the present invention, the upper structure of the footwear product includes a shoe upper body 19 attached to the sole body 1, and a shoelace 21 connected to the tongue 20 of the shoe upper body 19 and used to tighten the tongue 20; the shoelace 21 extends backward from the tongue 20 of the shoe upper body 19 to the side of the heel portion of the shoe upper body 19. The shoelace 21 driving assembly of the footwear product includes a shoelace 21 driving motor installed on the side of the heel portion of the shoe upper body 19, and the output end of the shoelace 21 driving motor is connected to the shoelace 21 and is used to tighten or loosen the shoelace 21.

[0084] Specifically, refer to Figure 1 , Figure 2 and Figure 5In the upper structure, a tongue 20 is connected to the upper body 19, and shoelaces 21 are connected to both sides of the tongue 20 in the width direction. The shoelaces 21 extend backward and are close to the heel of the upper body 19. A shoelace 21 driving motor is arranged at this position, and the output end of the shoelace 21 driving motor is connected to the shoelace 21, and the shoelace 21 can be tightened or loosened by the movement of the output end of the shoelace 21 output motor. On the basis of the above-mentioned sole structure, the footwear product also includes an upper structure and a shoelace 21 driving assembly. The upper structure is combined with the sole structure to form a complete footwear product. The addition of the shoelace 21 driving assembly realizes the automatic tightening or loosening function of the shoelace 21; the user does not need to tie the shoelaces 21 manually, which is convenient and quick, and improves the convenience of wearing and taking off shoes; at the same time, the tightness of the shoelaces 21 can be adjusted at any time according to different wearing needs, providing a more comfortable fit, and improving the overall comfort and functionality of the footwear product.

[0085] As a feasible implementation, the shoelace 21 driving motor may be an electric cylinder, which drives the shoelace 21 to be tightened or loosened by extending and retracting the output end of the electric cylinder in the length direction.

[0086] The control component 23 in the footwear product includes a battery and a switch; the battery is arranged at the rear end of the upper body 19 and is electrically connected to the embedded drive motor 9 and the shoelace 21 drive motor; the switch is arranged at the rear end of the upper body 19 and is electrically connected to the battery to control the on and off of the power supply of the battery to the embedded drive motor 9 and the shoelace 21 drive motor. Specifically, the battery can be embedded at the rear end of the upper body 19, or fixed on the surface of the upper body 19, which can be a conventional button battery, or a lithium battery with a specific shape customized according to the actual installation space. A switch is also arranged at the rear end of the upper body 19, which can be a touch switch, a press switch or a Bluetooth switch. According to different switch forms, it can realize different control modes for the embedded drive motor 9 and the shoelace 21 drive motor. The battery of the control component 23 provides power for the embedded drive motor 9 and the shoelace 21 drive motor, so that the position adjustment of the reinforcement 5 of the sole and the automatic tightening of the shoelace 21 can be realized. The setting of the switch is convenient for the user to control the work of the motor, and the operation is simple and easy to use. The battery is located at the rear end of the upper, which makes rational use of the upper space without affecting the overall appearance and wearing comfort of the shoe.

[0087] In the footwear product, the mask 24 is attached to the sole body 1 and the upper body 19, and is semi-enclosed around the heel of the sole body 1 and the upper body 19 to cover the embedded drive assembly 8, the shoelace 21 drive assembly and the control assembly 23. Specifically, the mask 24 can be bonded and fixed to the sole body 1 and the upper body 19, so as to protect the internal components, prevent the embedded drive assembly 8, the shoelace 21 drive assembly and the control assembly 23 from being affected by external collisions, water splashes or dust, etc., extend the service life of these components, and ensure their normal operation. The semi-enclosed design not only achieves effective protection, but also does not have too much impact on the overall appearance and wearing comfort of the shoes. At the same time, it can also enhance the overall aesthetics and sense of technology of the footwear product to a certain extent.

[0088] The mask 24 is made of thermoplastic polyurethane elastomer material and is translucent. The thermoplastic polyurethane elastomer material makes the mask 24 have good flexibility and wear resistance, can adapt to various deformations and frictions of the shoes during wearing, and is not easy to be damaged. The translucent property allows the user to observe the working status of the internal components to a certain extent, which increases the visibility and interest of the product. At the same time, it is also convenient for the user to promptly discover potential problems during use, such as whether the components have abnormal displacement, etc., which is convenient for timely maintenance and processing.

[0089] The description of the above specification and embodiments is used to explain the protection scope of the present invention, but does not constitute a limitation on the protection scope of the present invention. Through the enlightenment of the present invention or the above embodiments, ordinary technicians in this field can obtain modifications, equivalent substitutions or other improvements to the embodiments of the present invention or part of the technical features thereof through logical analysis, reasoning or limited experiments, which should be included in the protection scope of the present invention.
