TECHNICAL FIELD
[0001] The utility model relates to the technical field of shoe sole structure, specifically relates to a shoe sole structure and footwear product with embedded component of adjustable position. BACKGROUND
[0002] Footwear products include an upper and a sole structure. The upper can be formed of suitable materials to accommodate, secure and support a foot on the sole structure. The upper can cooperate with laces, Velcro or other fasteners to adjust the fit of the upper around the foot. A bottom portion of the upper proximate to a bottom surface of the foot is attached to the sole structure.
[0003] The sole structure includes different components arranged in layers and interfacing between the ground and the upper. At the bottom layer of the sole structure is an outsole of the sole structure, which provides wear resistance and adhesion to the ground, which can be formed of rubber or other suitable materials. Above the outsole is a midsole of the sole structure, which provides cushioning, resilience to the foot, and is at least partially formed of a polymer foamed material that deforms upon the foot exerting pressure thereon to achieve cushioning to the foot by attenuating the reaction force of the ground to the foot. An upper side surface of the midsole can define a footbed, which can be profiled to conform to the profile of the bottom surface of the foot. The sole structure can also include an insole or sockliner for improved comfort, which is fixedly or detachably attached to the upper side surface of the midsole and located in a shoe cavity defined by the midsole and the upper.
[0004] In current sole structures, in order to improve the bending stiffness of the sole structure in the longitudinal direction, a flat and rigid plate-like component with longitudinal stiffness is embedded in the sole structure, which can be made of carbon fiber, nylon, TPU or other suitable materials. Generally, the sole structure with embedded plates, in which the embedded plates are embedded and fixed in the midsole of the sole structure during the molding process of the sole structure, for example, the plate-like component is embedded during the molding process of the midsole. However, for different user groups, due to the difference in foot shape or the requirement for the bending stiffness of the sole structure in the longitudinal direction in different use scenarios, such footwear products with fixed embedded plates often cannot meet the user's needs.

[0023] Technical solution 17, based on technical solution 16: The mask is made of thermoplastic polyurethane elastomer and is semi-transparent.
[0024] As can be seen from the above description of this utility model, compared with the prior art, this utility model has the following beneficial effects:
[0025] Technical solution one provides a sole structure with an adjustable embedded component. The sole structure includes a sole body, an embedded component, and an embedded drive component. The embedded component includes a reinforcing member, which can be placed in a receiving cavity of the sole body. The reinforcing member itself can enhance the longitudinal bending rigidity of the sole body through the reinforcing part, so that when the user wears footwear products with this sole structure, the bending and rebound of the reinforcing member can provide better sole rolling performance. Furthermore, the embedded drive component can also drive the reinforcing member to adjust its position along the length direction in the receiving cavity, thereby flexibly changing the bending rigidity of different parts of the sole according to different user foot shapes or usage scenarios to meet different user needs.
[0026] The reinforcing component in the embedded assembly includes a reinforcing part and a connecting part. The reinforcing part is placed in the accommodating cavity to enhance the longitudinal bending rigidity of the sole body, while the connecting part extends from the opening on the side wall of the sole body and is connected to the embedded drive motor through a transmission mechanism. This arrangement allows both the embedded drive motor and the transmission mechanism to be located on the outside of the sole body, rather than being embedded inside. Embedding inside the sole body can easily lead to a loss of sole performance at the location of the embedded motor. By placing them on the outside of the sole body, not only is the sole performance preserved, but the assembly, maintenance, and replacement of the embedded drive assembly are also facilitated. However, placing the embedded drive motor outside the sole body would make it difficult for the embedded drive motor to drive the reinforcing component to adjust its position in the accommodating cavity. Therefore, this technical solution sets the reinforcing component as a structure where the connecting part can extend from the opening of the sole body. After the connecting part extends, it can form a transmission connection with the embedded drive motor outside the sole body through the transmission mechanism. At the same time, placing the transmission mechanism outside the sole body can also avoid the problem of failure or damage caused by friction between the transmission mechanism and the internal wall of the sole body during operation.
[0027] In technical solution two, the addition of two reinforcing members further improves the uniformity and stability of the overall longitudinal bending rigidity of the sole, enabling it to better adapt to the stress conditions in different areas of the sole. Furthermore, since both reinforcing members are independently controlled by a set of embedded drive motors and transmission mechanisms, the positions of the two reinforcing members relative to the sole body in the length direction can be adjusted according to actual needs, allowing for more precise adjustment of the rigidity at different positions of the sole, thereby meeting more complex usage requirements.
[0028] In technical solution three, the reinforcing part of the reinforcing member is designed as a structure of multiple extended arms arranged at intervals. Compared with the full-length reinforcing member, the structure of the reinforcing member in this technical solution can make its enhancement of the longitudinal bending rigidity of the sole structure within a suitable range, reducing the discomfort caused by the sole being difficult to bend when the user wears the shoe. It can also reduce the contact area with the cavity wall of the receiving cavity, reduce the friction with the cavity wall of the receiving cavity, and ensure that the positional change can be smoothly completed in the receiving cavity.
[0029] In technical solution four, the reinforcing part of the reinforcing component includes a first extension arm and a second extension arm. The straight design of the first extension arm near the outer side mainly enhances the longitudinal rigidity of the outer side of the sole, effectively resisting bending deformation of the outer side of the sole during walking or exercise. The combination of the inclined section and the second reinforcing section of the second extension arm not only optimizes the overall performance by forming a specific structure in the width direction through the special design of the inclined section, but also enhances the longitudinal rigidity of the sole near the midline through the second reinforcing section, so that the sole can better maintain structural stability when under stress, especially near the arch of the foot, thereby improving comfort and athletic performance.
[0030] In technical solution five, the second extension arms of the two reinforcing members are arranged in an alternating pattern in the width direction. By utilizing their synergistic effect, the two reinforcing members can provide greater longitudinal bending rigidity to the sole at the midline position in the width direction, reducing the impact of the decrease in longitudinal bending rigidity caused by the design of the reinforcing part of the reinforcing member 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 alternating second extension arms can also restrain and support each other, further improving the stability and torsional performance of the overall sole structure, effectively preventing excessive deformation of the sole under lateral or torsional forces, and improving the reliability of the sole in complex sports scenarios.
[0031] In technical solution six, the inclined segment of the second extension arm of the reinforcing member extends inclinedly from top to bottom in the thickness direction, and the two inclined segments have different inclination angles relative to the horizontal plane, so that the second extension arm of one reinforcing member crosses over and overlaps the second extension arm of the other reinforcing member, thereby forming a three-dimensional staggered structure between the two second extension arms, ensuring that they will not interfere with each other when their positions are adjusted individually; at the same time, the inclined extension structure of the inclined segment in the thickness direction of the reinforcing part also allows the reinforcing member to have further bending changes in the thickness direction. When bending at the forefoot part of the sole structure, it can better conform to the bending curve of the metatarsal position of the foot, thereby improving wearing comfort and providing all-round stable support for the user's foot.
[0032] In technical solution seven, the design of uniform thickness and partially flush structure ensures the installation stability and consistency of the reinforcement in the shoe sole cavity. When under stress, it can make the force evenly distributed on the entire reinforcement, avoiding local uneven force and stress concentration caused by uneven thickness or uneven structure, thereby extending the service life of the reinforcement and shoe sole structure, and also helping to improve the stability and predictability of the overall performance of the shoe sole.
[0033] In technical solution eight, the first and second limiting parts precisely restrict the position of the reinforcing member in the accommodating cavity, ensuring that the different extension arms of the reinforcing member will not loosen when adjusting their positions in the accommodating cavity, and also preventing unnecessary displacement during use; at the same time, the appropriate cavity wall distance design allows the reinforcing member to remain stable in the accommodating cavity, and to make minor adjustments within the allowable range when subjected to a certain external force, ensuring a tight fit between the reinforcing member and the sole body, and improving the overall reliability and performance stability of the sole structure.
[0034] In technical solution nine, the presence of the reinforcing component effectively enhances the structural strength of the opening area, reducing the problem of weak sole structure caused by the opening. During the extension and adjustment of the reinforcing component's connecting part, the reinforcing component can withstand some stress, preventing the opening from being excessively deformed or damaged due to force, thereby protecting the integrity of the overall sole structure, ensuring the normal operation of the embedded drive components, and also helping to extend the service life of the sole.
[0035] In technical solution ten, the linear reciprocating motion of the motor can be stably transmitted to the reinforcing member connection part through the cooperation of the limiting tube and the sliding member, thereby realizing the precise position adjustment of the reinforcing member in the accommodating cavity; the limiting tube plays a guiding and limiting role for the sliding member, ensuring the accuracy of the moving direction of the reinforcing member, reducing deviation and jamming during the movement process, improving the reliability and stability of the drive system, and thus realizing precise control of the rigidity of the shoe sole.
[0036] In technical solution eleven, the rotational motion of the motor is converted into the linear motion of the threaded component by the screw drive of the lead screw and threaded component. This has the advantages of high transmission accuracy and large transmission ratio. It can more precisely control the position adjustment of the reinforcing component and achieve fine adjustment of the longitudinal bending rigidity of the sole, meeting the needs of application scenarios with high requirements for sole performance. At the same time, the lead screw drive structure is compact and occupies relatively little space, which is conducive to arranging drive components in the limited space of the sole. In addition, the transmission efficiency is high, which can reduce the energy consumption of the motor.
[0037] In technical solution twelve, the reinforcing component 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 adding too much weight to the sole, providing excellent support performance. Nylon has good wear resistance, toughness, and a certain degree of rigidity, which allows the reinforcing component to enhance the rigidity of the sole while also having a certain impact resistance, extending the service life of the sole. Thermoplastic polyurethane elastomer combines elasticity and rigidity, which can effectively enhance the rigidity of the sole while maintaining the flexibility and comfort of the sole to a certain extent, adapting to different sports conditions and foot movements.
[0038] In technical solution thirteen, the reinforcing component is made of nylon or thermoplastic polyurethane elastomer. Nylon reinforcing components offer high strength and abrasion resistance, effectively resisting wear and deformation caused by stress at the opening, thus protecting the sole structure. Reinforcing components made of thermoplastic polyurethane elastomer provide a certain level of strength while also possessing good elasticity and flexibility. This allows them to enhance the strength of the opening structure while matching the elastic characteristics of the sole itself, preventing the reinforcing component from being too stiff and affecting the overall comfort and flexibility of the sole.
[0039] Technical solution fourteen provides a footwear product that, in addition to the aforementioned sole structure, also includes an upper structure and a lace drive assembly. The upper structure and sole structure are combined to form a complete footwear product. The addition of the lace drive assembly enables automatic tightening or loosening of the laces; users do not need to manually tie the laces, making it convenient and quick, and improving the ease of putting on and taking off shoes; at the same time, the tightness of the laces 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.
[0040] Technical solution fifteen also includes a control component. The battery in the control component provides power to the embedded drive motor and the shoelace drive motor, enabling the adjustment of the reinforcement position on the sole and the automatic tightening of the shoelaces. The switch is conveniently located for users to control the motor's operation; it is simple and easy to use. The battery is located at the rear of the upper, making efficient use of the upper space without affecting the overall appearance and wearing comfort of the shoe.
[0041] In technical solution sixteen, the shield protects the internal components, preventing the embedded drive components, shoelace drive components, and control components from external impacts, water splashes, or dust, thus extending their lifespan and ensuring their normal operation. The semi-enclosed design provides effective protection without significantly affecting the overall appearance and wearing comfort of the shoe. Furthermore, it can enhance the overall aesthetics and technological feel of the footwear to some extent.
[0042] In technical solution seventeen, the thermoplastic polyurethane elastomer material gives the cover excellent flexibility and abrasion resistance, enabling it to adapt to various deformations and frictions during shoe wear and preventing damage. Its semi-transparent nature allows users to observe the working status of internal components to some extent, increasing the product's visibility and appeal. It also facilitates timely detection of potential problems during use, such as abnormal component displacement, enabling prompt maintenance and handling. Attached Figure Description

[0055] In the claims, description and accompanying drawings of this utility model, the terms "comprising", "having", and variations thereof are used to mean "including but not limited to".
[0056] This utility model relates to a footwear product, as described in the following embodiment. Figure 1 and Figure 2 The footwear product includes an upper structure, a lace drive assembly 21, a control assembly 23, a cover 24, and a sole structure with an adjustable embedded component.
[0057] First, the sole structure with the adjustable embedded component will be described.
[0058] The sole structure includes: a sole body 1, which has a flattened accommodating cavity 2 extending along the length and width directions at the middle position in the thickness direction; the accommodating cavity 2 is located at the forefoot and arch portions of the sole body 1, and has an opening 3 extending along the length direction and communicating with the outside of the sole body 1 on the side wall of the arch portion; an insert assembly 4, which includes a reinforcing member 5 placed in the accommodating cavity 2, the reinforcing member 5 being limited by the upper and lower cavity walls in the thickness direction of the accommodating cavity 2, and having a reinforcing part 6 and a connecting part 7; the reinforcing part 6 extends along the length direction... The connecting portion 7 extends and is placed in the accommodating cavity 2 to enhance the longitudinal bending rigidity of the sole body 1, and extends out of the opening 3; and the embedded drive assembly 8 includes an embedded drive motor 9 and a transmission mechanism 10; the embedded drive motor 9 is mounted on the side wall of the heel portion of the sole body 1; the transmission mechanism 10 is drivenly connected to the output end of the embedded drive motor 9, and its output end is connected to the connecting portion 7 of the reinforcing member 5, so that when the embedded drive motor 9 is running, it drives the reinforcing member 5 to adjust its position in the accommodating cavity 2 along the length direction.
[0059] The embedded component 4 includes two reinforcing members 5 arranged along the width direction; the sole body 1 has openings 3 on both sides of its width direction, and the connecting part 7 of the reinforcing member 5 located on the same side as the opening 3 extends out of the opening 3; the embedded drive component 8 has a set of embedded drive motors 9 and transmission mechanisms 10 connected in transmission on both sides of the sole body 1 in the width direction, and the connecting part 7 of the reinforcing member 5 located on the same side as the set 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 structure, specifically the sole body 1, comprises the outsole and the midsole. The outsole is attached to the midsole via methods such as hot melting, hot pressing, or gluing. The midsole has a certain thickness to provide users with rebound and cushioning performance. The materials of the outsole and midsole can be selected according to actual needs, which will not be elaborated here.
[0061] Reference Figure 4 The sole body 1 has a receiving cavity 2, which is a flat chamber structure extending along both the length and width directions. Its distribution is located in the forefoot and arch areas of the sole body 1. For conventional sole structures, based on their correspondence with the foot, they can be divided into the forefoot, arch, and heel areas. There are no strict dividing lines between these areas, but those skilled in the art can clearly distinguish between them. Furthermore, because the outer contour of the sole body 1 matches the outer contour of the foot's bottom surface, the width of the sole body 1 exhibits a trend of increasing, decreasing, and then increasing again from front to back. The width is smaller at the front of the forefoot, largest in the middle of the forefoot, decreases again in the arch area, and then slightly increases in the heel area.
[0062] The opening 3 on the sole body 1 is mainly located at the arch area. Of course, referring to... Figure 1 The opening 3 is also partially located in the forefoot and heel areas, which is related to the range of motion of the reinforcement 5 in the embedded component 4 within the receiving cavity 2. The opening 3 on the sole body 1 is flat to expose less of the receiving cavity 2 within the sole body 1.
[0063] The forming of the accommodating cavity 2 within the sole body 1 can be achieved by dividing the midsole of the sole body 1 into upper and lower parts, forming a portion of the accommodating cavity 2 separately, and then merging these two parts into a single midsole. Alternatively, a spacer mold can be placed at the location of the accommodating cavity 2, and the midsole can be formed directly through foaming. After the midsole is formed, the spacer mold can be removed from the opening 3 on the sole body 1.
[0064] Reference Figure 3The embedded component 4 includes two reinforcing members 5, which are arranged in the receiving cavity 2 along the width direction. Openings 3 are also provided on both sides of the sole body 1 along the width direction, allowing the connecting portions 7 of the reinforcing members 5 to extend from the corresponding openings 3 to the outside of the sole body 1. The reinforcing portions 6 of the reinforcing members 5 are always located within the receiving cavity 2, enhancing the longitudinal bending rigidity of the sole body 1. Through the limiting effect of the receiving cavity 2 on the reinforcing members 5, their position can be adjusted along the length direction within the receiving cavity 2, thereby precisely controlling the longitudinal bending strength of the sole structure in different parts. The two reinforcing members 5 further improve the uniformity and stability of the overall longitudinal bending rigidity of the sole, better adapting to the stress conditions in different areas of the sole.
[0065] The embedded drive assembly 8 includes two sets of embedded drive motors 9 and a transmission mechanism 10, with one embedded drive motor 9 and a correspondingly connected transmission mechanism 10 forming a set. The embedded drive motor 9 is bonded and fixed to the side wall of the heel portion of the sole body 1. At its installation position, the side wall of the sole body 1 can be slightly recessed to form a groove structure to accommodate the embedded drive motor 9, reducing the degree of protrusion of the embedded drive motor 9. Furthermore, the output end of the embedded drive motor 9 has two different output methods: one is that its output end can extend and retract along the length direction, for example, the embedded drive motor 9 uses an electric cylinder; the other is that its output end can rotate around an axis along the length direction, for example, the embedded drive motor 9 uses a DC motor. It is easy to understand that, since the embedded drive motor 9 is set on the side wall of the heel portion of the sole body 1 in this invention, there is obviously not enough space in the width direction for the embedded drive motor 9 to be installed. Therefore, the installation direction of the embedded drive motor 9 is such that its length direction is consistent with the length direction of the sole body 1, and its output end faces the front end of the sole body 1.
[0066] The transmission mechanism 10 is positioned before the embedded drive motor 9 and connected to the output end of the embedded drive motor 9. It transmits the movement of the output end of the embedded drive motor 9 to the reinforcing part 6 through the connection between its output end and the connecting part 7 of the reinforcing member 5, thereby driving the reinforcing part 6 to adjust its position within the accommodating cavity 2. Furthermore, since there are two sets of embedded drive motors 9 and transmission mechanisms 10, each corresponding to one of the reinforcing members 5, the positions of the two reinforcing members 5 relative to the sole body 1 in the length direction can be adjusted according to actual needs. This allows for more precise adjustment of the rigidity of different positions on the sole, thus meeting more complex usage requirements.
[0067] In this sole structure with an adjustable embedded component, the reinforcing member 5 itself can enhance the longitudinal bending rigidity of the sole body 1 through the reinforcing part 6, so that when the user wears footwear products with this sole structure, the bending and rebound of the reinforcing member 5 can provide better sole rolling performance; and the embedded driving component 8 can also drive the reinforcing member 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 different foot shapes or usage scenarios of different users, so as to meet the different needs of users. The reinforcing member 5 in the embedded component 4 includes a reinforcing part 6 and a connecting part 7. The reinforcing part 6 is placed in the receiving cavity 2 to enhance the longitudinal bending rigidity of the sole body 1, while the connecting part 7 extends from the opening 3 on the side wall of the sole body 1 and is connected to the embedded drive motor 9 through the transmission mechanism 10. This arrangement allows both the embedded drive motor 9 and the transmission mechanism 10 to be located on the outside of the sole body 1, rather than embedded inside. Embedding inside the sole body 1 can easily lead to a loss of sole performance at the location of the embedded motor. By placing them on the outside of the sole body 1, not only is the sole performance not compromised, but also… It facilitates the assembly, maintenance, and replacement of the embedded drive assembly 8; however, placing the embedded drive motor 9 outside the sole body 1 makes it difficult for the embedded drive motor 9 to drive the reinforcing member 5 to adjust its position in the accommodating cavity 2. Therefore, this technical solution sets the reinforcing member 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 extends, it can form a transmission connection with the embedded drive motor 9 outside the sole body 1 through the transmission mechanism 10. At the same time, placing the transmission mechanism 10 outside the sole body 1 can also avoid the problem of failure or damage caused by friction between the transmission mechanism 10 and the inner wall of the sole body 1 during operation.
[0068] As one aspect of the sole structure involved in this embodiment, the structure of the reinforcing member 5 will be 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 spaced apart along the width direction and extending along the length direction, the lower end of each extension arm being 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 linearly along the length direction to form a first reinforcing segment 13; the second extension arm 12 is close to the centerline of the sole body 1 in the width direction, and its portion near the connecting portion 7 extends obliquely from the outer side of the sole body 1 toward the centerline in the width direction to form an inclined segment 14, and its portion relatively far from the connecting portion 7 extends linearly along the length direction to form a second reinforcing segment 15.
[0070] The inclined segments 14 of the second extension arms 12 of the two reinforcing members 5 overlap in the thickness direction, so that the two reinforcing members 5 are staggered in the width direction. The inclined segments 14 of the second extension arms 12 of the reinforcing members 5 extend inclinedly from top to bottom in the thickness direction, and the inclination angles of the inclined segments 14 of the second extension arms 12 of the two reinforcing members 5 relative to the horizontal plane are not the same, so that the second extension arm 12 of one reinforcing member 5 crosses over the second extension arm 12 of the other reinforcing member 5 in the thickness direction and overlaps in the thickness direction. The thickness of the reinforcing members 5 is uniformly distributed, and the first extension arms 11 and connecting portions 7 of the two reinforcing members 5 are flush in the thickness direction, and the second reinforcing segments 15 of the second extension arms 12 of the two reinforcing members 5 are flush in the thickness direction.
[0071] Specifically, refer to Figure 3 The reinforcing member 5 includes a reinforcing portion 6 and a connecting portion 7. The connecting portion 7 extends from the opening 3 on the sole body 1 to the outside of the sole body 1 and is connected to the transmission mechanism 10 of the embedded drive assembly 8 to drive the reinforcing member 5 to adjust its position in the receiving cavity 2. The reinforcing portion 6 is integrally formed with the connecting portion 7 and includes two extension arms extending along the length direction: a first extension arm 11 near the outer side of the sole body 1 and a second extension arm 12 near the center line in the width direction of the sole body 1. In short, the first extension arm 11 is positioned closer to the outer side 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, thereby forming a knife-fork shaped structure for the reinforcing member 5. The reinforcing part 6 of the reinforcing member 5 is designed as a structure of multiple extended arms arranged at intervals. Compared with the full-length reinforcing member 5, the structure of the reinforcing member 5 in this technical solution can make its enhancement of the longitudinal bending rigidity of the sole structure within a suitable range, reducing the discomfort caused by the inability of the sole to bend when the user wears the shoe. It can also reduce the contact area with the cavity wall of the receiving cavity 2, reduce the friction with the cavity wall of the receiving cavity 2, and ensure that the position change can be smoothly completed in the receiving cavity 2.
[0072] The first extension arm 11 extends forward in a straight line from its connection point with the connecting part 7, thus forming the first reinforcing section 13. Of course, in practical applications, the width of the first extension arm 11 is not constant, but gradually decreases from back to front to increase the connection strength between the first extension arm 11 and the connecting part 7. The straight design of the first extension arm 11 near the outer side mainly enhances the longitudinal rigidity of the outer side of the sole, effectively resisting bending deformation of the outer side of the sole during walking or exercise.
[0073] Since the connecting part 7 needs to extend out of the opening 3, and the connecting part 7 is located in an inward position, the second extension arm 12 is provided with an inclined section 14 and a second reinforcing section 15. The inclined section 14 extends inclinedly from the inside out and from front to back, so that the second reinforcing section 15 and the connecting part 7 are integrated. The second reinforcing section 15 extends forward in a straight line from the inclined section 14. Of course, in practical applications, the width of the second extension arm 12 also gradually decreases from back to front to increase the connection strength between the second extension arm 12 and the connecting part 7. The combination of the inclined section 14 and the second reinforcing 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 reinforcing section 15. This allows the sole to maintain structural stability better when under stress, especially near the arch, thus improving comfort and athletic performance.
[0074] Furthermore, referring to Figure 3 and Figure 4 The inclined segments 14 of the two second extension arms 12 extend inclinedly from top to bottom and from back to front in the thickness direction, and the inclination angles of the two inclined segments 14 relative to the horizontal plane are not the same, so that the second extension arms 12 of the two reinforcing members 5 overlap at the position of the inclined segments 14. Specifically, the inclined segment 14 of the upper second extension arm 12 has a smaller inclination angle relative to the horizontal plane, that is, the slope of this inclined segment 14 is gentler, while the inclined segment 14 of the other second extension arm 12 has a steeper slope. This allows the two inclined segments 14 to be staggered without interfering with each other when the two reinforcing members 5 are in the same length direction. At the same time, the two second reinforcing segments 15 before the inclined segment 14 extend straight, and the two second reinforcing segments 15 are flush with each other in the thickness direction.
[0075] The second extension arms 12 of the two reinforcing members 5 are arranged in an alternating manner in the width direction. By utilizing their synergistic effect, the two reinforcing members 5 can provide greater longitudinal bending rigidity to the sole at the midline position in the width direction, reducing the impact of the decrease in longitudinal bending rigidity caused by the design of the reinforcing part 6 of the reinforcing member 5 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 alternating second extension arms 12 can also restrain and support each other, further improving the stability and torsional performance of the overall sole structure, effectively preventing excessive deformation of the sole under lateral or torsional forces, and improving the reliability of the sole in complex sports scenarios. The inclined segment 14 of the second extension arm 12 of the reinforcing member 5 extends inclinedly from top to bottom in the thickness direction, and the two inclined segments 14 have different inclination angles relative to the horizontal plane, so that the second extension arm 12 of one reinforcing member 5 passes over the second extension arm 12 of the other reinforcing member 5 and overlaps, thereby forming a three-dimensional interlaced structure between the two second extension arms 12, ensuring that they will not interfere with each other when their positions are adjusted individually; at the same time, the inclined extension structure of the inclined segment 14 in the reinforcing part 6 in the thickness direction also allows the reinforcing member 5 to have further bending changes in the thickness direction. When bending in the forefoot part of the sole structure, it can better fit the bending curve of the metatarsal position of the foot, thereby improving wearing comfort and providing all-round stable support for the user's foot.
[0076] The uniform thickness and partially flush design ensure the stability and consistency of the reinforcement 5 in the shoe sole cavity 2. When under stress, the force can be evenly distributed on the entire reinforcement 5, avoiding localized uneven force and stress concentration caused by uneven thickness or uneven structure. This extends the service life of the reinforcement 5 and the shoe sole structure, and also helps to improve the stability and predictability of the overall performance of the shoe sole.
[0077] Furthermore, the reinforcing member 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 adding too much weight to the sole, providing excellent support performance. Nylon has good wear resistance, toughness, and a certain degree of rigidity, which allows the reinforcing member 5 to enhance the rigidity of the sole while also having a certain degree of impact resistance, extending the service life of the sole. Thermoplastic polyurethane elastomer combines elasticity and rigidity, which can effectively enhance the rigidity of the sole while maintaining the flexibility and comfort of the sole to a certain extent, adapting to different sports conditions and foot movements. In this embodiment, the reinforcing member 5 is preferably made of carbon fiber.
[0078] Reference Figure 4The accommodating cavity 2 has a first limiting part 16 at the position corresponding to the first extension arm 11 of the two reinforcing members 5, and a second limiting part 17 at the position corresponding to the second extension arm 12 of the two reinforcing members 5. The distance between the upper and lower cavity walls of the first limiting part 16 is adapted to the thickness of the reinforcing member 5, and the distance between the upper and lower cavity walls of the second limiting part 17 is adapted to the thickness dimension of the reinforcing member 5 defined by the second reinforcing section 15 of the second extension arm 12 and the first extension arm 11.
[0079] Specifically, the accommodating cavity 2 has different thicknesses at the first limiting portion 16 and the second limiting portion 17, which are defined by the upper and lower cavity walls of the accommodating cavity 2. The first limiting portion 16 is located on both sides of the accommodating cavity 2 in the width direction, corresponding to the first extension arms 11 of the two reinforcing members 5. The second limiting portion 17 is located in the middle of the accommodating cavity 2 in the width direction, corresponding to the second extension arms 12 of the two reinforcing members 5. Since the inclined section 14 of the second extension arm 12 extends obliquely in the thickness direction, there is a height difference in the thickness direction from the point where the second extension arm 12 connects to the connecting portion 7 up to the second reinforcing section 15 of the second extension arm 12, thus defining the dimension of the second extension arm 12 in the thickness direction. The thickness of the second limiting portion 17 is approximately the same as the dimension of the second extension arm 12 in the thickness direction. The first limiting part 16 and the second limiting part 17 precisely limit the position of the reinforcing member 5 in the accommodating cavity 2, ensuring that the different extension arms of the reinforcing member 5 will not loosen when adjusting their positions in the accommodating cavity 2, and also preventing unnecessary displacement during use; at the same time, the appropriate cavity wall distance design allows the reinforcing member 5 to remain stable in the accommodating cavity 2, and to make minor adjustments within the allowable range when subjected to a certain external force, ensuring a tight fit between the reinforcing member 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 provided on the sole body 1. The reinforcing member 18 is fixed at the opening 3 of the sole body 1 and surrounds the opening 3 to reduce the deformation of the opening 3. (Refer to...) Figure 1 and Figure 2The reinforcing member 18 is an elliptical, flat, ring-shaped component that can be attached to the sidewall of the sole body 1. The portion enclosed by its inner ring perfectly matches the area of the opening 3 on the sole body 1, thus maintaining the fixed shape of the opening 3. The presence of the reinforcing member 18 effectively enhances the structural strength of the opening 3 area, reducing the structural weakness of the sole caused by the opening 3. During the extension and adjustment of the connecting portion 7 of the reinforcing member 5, the reinforcing member 18 can withstand some stress, preventing excessive deformation or damage to the opening 3 due to force, thereby protecting the integrity of the overall sole structure, 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 nylon reinforcement 18 provides high strength and abrasion resistance, effectively resisting wear and deformation caused by stress at the opening 3 and protecting the sole structure. The reinforcement 18, made of thermoplastic polyurethane elastomer, provides a certain strength while also having 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 overall comfort and flexibility of the sole being affected by the reinforcement 18 being too hard.
[0081] In one embodiment of the embedded drive assembly 8, the output end of the embedded drive motor 9 is adapted to reciprocate along the length direction; the transmission mechanism 10 includes a limiting tube fixed to the sole body 1 and extending along the length direction, and a sliding member located within the limiting tube; the sliding member is connected to the output end of the embedded drive motor 9, and serves as the output end of the transmission mechanism 10 connected to the connecting portion 7 of the reinforcing member 5. Specifically, the limiting 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 provided on its side facing the sole body 1. The sliding member is slidably installed within the limiting tube, and a connecting arm extending from the through groove can be provided on the sliding member. The thickness of the connecting arm can be adapted to the groove width of the through groove, so that the sliding member will not wobble in the limiting tube. The connecting arm can be connected to the connecting portion 7 of the reinforcing member 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, whose output end can reciprocate along the length direction, thereby driving the sliding member to reciprocate along the length direction, and in turn driving the reinforcing member 5 to reciprocate along the length direction. Through the cooperation of the limiting tube and the sliding member, the linear reciprocating motion of the motor can be stably transmitted to the connecting part 7 of the reinforcing member 5, thereby realizing the precise position adjustment of the reinforcing member 5 in the accommodating cavity 2. The limiting tube plays a guiding and limiting role for the sliding member, ensuring the accuracy of the movement direction of the reinforcing member 5, reducing deviations and jamming during the movement, improving the reliability and stability of the drive system, and thus realizing precise control of the rigidity of the shoe sole.
[0082] Alternatively, as another embodiment of the embedded drive assembly 8, the output end of the embedded drive motor 9 is adapted to reciprocate about an axis in the length direction; the transmission mechanism 10 includes a lead screw rotatably mounted on the sole body 1 about an axis in the length direction and extending along the length direction, and a threaded component screwed to the lead screw; the lead screw is connected to the output end of the embedded drive motor 9 and adapted to receive rotational torque, and the threaded component serves as the output end of the transmission mechanism 10 and is connected to the connecting portion 7 of the reinforcing member 5. Specifically, both ends of the lead screw are rotatably mounted on the sole body 1, for example, bearings are embedded in the sole body 1, and the two ends of the lead screw are fixed to the inner rings of the bearings. At the same time, the end of the lead screw facing the embedded drive motor 9 is connected to the output end of the embedded drive motor 9. The embedded drive motor 9 used here can be a DC motor, whose output end rotates to output torque, thereby driving the lead screw to rotate. A threaded component is threadedly connected to the lead screw, and this threaded component is connected to the connecting portion 7 of the reinforcing member 5. When the lead screw rotates under the drive of the embedded drive motor 9, the reinforcing member 5, located in the accommodating cavity 2, acts as a limit for the threaded component, preventing it from rotating with the lead screw. Instead, the threaded component moves along its length under the influence of the lead screw's rotation, thereby adjusting the position of the reinforcing member 5 within the accommodating cavity 2. Utilizing the screw-connected transmission between the lead screw and the threaded component, the rotational motion of the motor is converted into the linear motion of the threaded component, offering advantages such as high transmission accuracy and a large transmission ratio. This allows for more precise control of the reinforcing member 5's position adjustment, enabling fine-tuning of the longitudinal bending rigidity of the shoe sole, meeting the performance requirements of high-performance shoe sole applications. Furthermore, the lead screw transmission structure is compact, occupying relatively little space, which is beneficial for arranging drive components within the limited space of the shoe sole, and its high transmission efficiency reduces motor energy consumption.
[0083] As another aspect of the footwear product involved in this utility model embodiment, the upper structure of the footwear product includes an upper body 19 attached to the sole body 1, and a shoelace 21 connected to the tongue 20 of the upper body 19 and used to tighten the tongue 20; the shoelace 21 extends rearward from the position of the tongue 20 of the upper body 19 to the side of the heel portion of the upper body 19. The shoelace 21 driving assembly of the footwear product includes a shoelace 21 driving motor mounted on the side of the heel portion of the upper body 19, and the output end of the shoelace 21 driving motor is connected to the shoelace 21 and used to tighten or loosen the shoelace 21.
[0084] Specifically, refer to Figure 1 , Figure 2 and Figure 5In this shoe upper structure, a shoe tongue 20 is connected to the shoe upper body 19, and shoelaces 21 are connected to both sides of the shoe tongue 20 in the width direction. The shoelaces 21 extend backward and are close to the heel of the shoe upper body 19. A shoelace 21 drive motor is set at this position, and the output end of the shoelace 21 drive motor is connected to the shoelaces 21. The movement of the output end of the shoelace 21 drive motor can tighten or loosen the shoelaces 21. This footwear product, based on the above-mentioned sole structure, also includes an upper structure and a shoelace 21 drive assembly. The upper structure and sole structure are combined to form a complete footwear product. The addition of the shoelace 21 drive assembly enables the automatic tightening or loosening function of the shoelaces 21; users do not need to manually tie the shoelaces 21, which is convenient and quick, improving the convenience of putting on 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 one feasible implementation method, the drive motor for the shoelace 21 can be an electric cylinder. By extending and retracting the output end of the electric cylinder in the length direction, the shoelace 21 can be tightened or loosened.
[0086] The control component 23 in this footwear product includes a battery and a switch. The battery is located 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 located at the rear end of the upper body 19 and is electrically connected to the battery to control the power supply from 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 fixedly mounted on the surface of the upper body 19. It 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 provided at the rear end of the upper body 19. This switch can be a touch switch, a push switch, or a Bluetooth switch. Depending on the switch type, it can realize different control methods for the embedded drive motor 9 and the shoelace 21 drive motor. The battery of the control component 23 provides power to the embedded drive motor 9 and the shoelace 21 drive motor, enabling the adjustment of the position of the sole reinforcement 5 and the automatic tightening function of the shoelace 21. The switch is convenient for users to control the operation of the motors, and the operation is simple and easy to learn. The battery is located at the rear of the shoe upper, making efficient use of the space without affecting the overall appearance and comfort of the shoe.
[0087] In this footwear product, a cover 24 is attached to the sole body 1 and the upper body 19, and is semi-enclosed around the heel area of the sole body 1 and the upper body 19 to cover the embedded drive component 8, the shoelace 21 drive component, and the control component 23. Specifically, the cover 24 can be bonded and fixed to the sole body 1 and the upper body 19, thereby protecting the internal components and preventing the embedded drive component 8, the shoelace 21 drive component, and the control component 23 from external impacts, water splashes, or dust, extending the service life of these components and ensuring their normal operation. The semi-enclosed design achieves effective protection without significantly affecting the overall appearance and wearing comfort of the shoe. At the same time, it can also enhance the overall aesthetics and technological feel of the footwear product to a certain extent.
[0088] The cover 24 is made of thermoplastic polyurethane elastomer and is semi-transparent. The thermoplastic polyurethane elastomer material gives the cover 24 good flexibility and abrasion resistance, allowing it to adapt to various deformations and frictions during shoe wear and preventing damage. The semi-transparency allows users to observe the working status of the internal components to some extent, increasing the product's visibility and appeal. It also facilitates timely detection of potential problems during use, such as abnormal component displacement, enabling prompt maintenance and handling.
[0089] The foregoing description of the specifications and embodiments is intended to explain the scope of protection of this utility model, but does not constitute a limitation on the scope of protection of this utility model. Modifications, equivalent substitutions, or other improvements to the embodiments of this utility model or a portion thereof that can be obtained by those skilled in the art through logical analysis, reasoning, or limited experimentation, based on the teachings of this utility model or the foregoing embodiments, should all be included within the scope of protection of this utility model.
