Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of protective equipment, and particularly relates to an ankle protection device. Background Art
[0002] The ankle joint is composed of the articular surfaces at the lower ends of the tibia and fibula and the trochlea of the talus, so it is also called the talocrural joint. The lower articular surface of the tibia and the medial and lateral ankle articular surfaces together form a "冂"-shaped joint fossa that accommodates the trochlea of the talus (articular head). Since the trochlear articular surface is wider in the front and narrower in the back, when the foot is dorsiflexed, the wider front part enters the fossa and the joint is stable; but when the foot is plantarflexed, such as when walking downhill, the narrower rear part of the trochlea enters the fossa, the ankle joint is loose and can make lateral movements, and at this time the ankle joint is prone to sprain, among which adduction injuries are the most common, because the lateral malleolus is longer and lower than the medial malleolus, which can prevent the talus from excessive valgus.
[0003] Ankle joint injuries often occur in some sports. For example, in extreme sports such as skydiving, adduction and valgus injuries are more likely to occur, and even fracture and dislocation may occur. Therefore, ankle protection devices are often worn for protection. However, the current ankle protection devices usually only have a cloth wearing structure, and due to the poor limiting effect of the cloth wearing structure, the protection effect is poor.

[0048] The following will clearly and completely describe the technical solutions in the embodiments of the utility model in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model. In the description of the utility model, unless otherwise specified, "multiple" means 2 or more, and "several" means 1 or more. In addition, unless otherwise specified, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated.
[0049] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.
[0050] In the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0051] In the description of the present invention, the description with reference to the terms "one embodiment", "some optional implementations" or "some optional embodiments" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.
[0052] At present, ankle injuries often occur in some sports. For example, in extreme sports such as skydiving, adduction and eversion injuries are more likely to occur, and even fractures and dislocations may occur. Therefore, ankle braces are often worn for protection. However, current ankle braces usually only have flexible cloth wearing structures. Due to the poor restriction effect and insufficient support force of the cloth wearing structure, the protective effect is poor. The utility model combines the cooperation of flexible wearable parts and rigid wearable parts, and can provide support through the rigid wearable parts after the flexible wearable parts are used for buffering, which can provide users with a comfortable wearing experience and excellent protective effect.
[0053] See also Figure 1 An embodiment of the utility model provides an ankle protection device, including: a rigid wearing piece 10 and a flexible wearing piece 20.
[0054] Please also read Figure 1 and Figure 2, the rigid wearable article 10 forms a first wearable space 11; the flexible wearable article 20 forms a second wearable space 21; when the ankle support device is in the wearing state, the flexible wearable article 20 is worn on the foot of the human body, and the flexible wearable article 20 and at least part of the foot of the human body are located in the first wearable space 11. In this embodiment, the rigid wearable article 10 and the flexible wearable article 20 can be independent components without being connected to each other. Of course, the rigid wearable article 10 and the flexible wearable article 20 can also be connected through a connecting structure, so as to facilitate storage and not be easily lost.
[0055] The user can wear the flexible wearable article 20 on the foot so that the ankle joint is located in the second wearing space 21, and the rigid wearable article 10 is arranged on the outside of the flexible wearable article 20 so that at least part of the flexible wearable article 20 is located in the first wearing space 11. Since the rigid wearable article 10 is relatively large in size and rigid, the rigid wearable article 10 can be worn on the outside of the user's boots, while at least part of the flexible wearable article 20 is located on the inside of the user's boots. A layer of boot wall is separated between the rigid wearable article 10 and the flexible wearable article 20, so as to facilitate wearing and improve comfort. Of course, according to the actual structure and usage scenarios of the rigid wearable article 10 and the flexible wearable article 20, the rigid wearable article 10 and the flexible wearable article 20 can also adopt other suitable wearing methods, such as wearing the rigid wearable article 10 directly on the outside of the flexible wearable article 20.
[0056] Please also read Figures 3 to 6 The rigid wearable article 10 has a first binding structure 12 and a second binding structure 13, the first binding structure 12 and the second binding structure 13 are movably connected, and a first limiting structure 30 is arranged between the first binding structure 12 and the second binding structure 13. When the ankle protection device is worn on the foot of a human body, the first binding structure 12 is bound to the leg of the human body, and the second binding structure 13 is bound to the foot of the human body. The first limiting structure 30 can limit the inward turning angle and / or outward turning angle of the second binding structure 13 compared with the first binding structure 12, so as to limit the adduction angle and / or eversion angle of the ankle joint of the human foot, thereby achieving the limitation of the adduction angle and / or eversion angle of the ankle joint of the human foot.
[0057] When the user's foot lands on the ground, the ankle joint tends to adduct and evert, and the flexible wearable article 20 can first provide a certain impact relief for the ankle joint to achieve preliminary protection, and then the rigid wearable article 10 can provide strong support for the ankle joint, thereby making up for the insufficient support of the flexible wearable article 20. Through the coordinated protection of the flexible wearable article 20 and the rigid wearable article 10, the protection effect is better; at the same time, because the flexible wearable article 20 can prevent the user's ankle joint from being directly subjected to the support force or squeezing force of the rigid wearable article 10, the instantaneous load on the ankle joint is avoided, which effectively relieves the pressure on the stress concentration point of the ankle, reduces the possibility of ankle joint damage, and improves the user's touch experience.
[0058] It should be noted that the flexible wearable component 20 is partially or entirely made of a flexible material. The flexible material usually has good ductility and toughness, and can deform to a certain extent when subjected to force without losing its original structure and function. Therefore, when the ankle joint tends to adduct or evert, the flexible wearable component 20 can first provide a certain degree of protection and a relatively gentle buffering effect to the ankle joint. The rigid wearable component 10 is partially or entirely made of a rigid material. The rigid material has a high hardness and high compressive and flexural strength. Therefore, when the second binding structure 13 is flipped relative to the first binding structure 12 and is restricted by the first limiting structure 30, the first binding structure 12 and the second binding structure 13 are not easily deformed due to their high hardness, and can provide stable support for the legs and feet, thereby better limiting the position of the foot relative to the leg, thereby limiting the ankle joint and not prone to adduction and eversion.
[0059] Please also read Figures 3 to 6The specific structure of the first limiting structure 30 can be designed according to actual needs. In some optional embodiments, the first limiting structure 30 includes an inward limiting portion 31 and an outward limiting portion 32; the inward limiting portion 31 and the outward limiting portion 32 are arranged on the first binding structure 12 or the second binding structure 13, and the inward limiting portion 31 and the outward limiting portion 32 are used to limit the inward turning angle and the outward turning angle of the second binding structure 13 compared with the first binding structure 12. In this embodiment, the inward limiting portion 31 and the outward limiting portion 32 are arranged on the second binding structure 13 as an example for description. When the ankle joint of the human body shows a tendency to adduct, the foot of the human body will turn inside the legs relative to the legs, and the foot will drive the second binding structure 13 to turn inward relative to the first binding structure 12. When the adduction limiting portion 31 abuts against the first binding structure 12, the second binding structure 13 cannot continue to turn inward, and the adduction limiting portion 31 limits the inward turning angle of the second binding structure 13, thereby limiting the inward turning of the foot relative to the leg, thereby avoiding adduction of the ankle joint to protect the ankle joint. Similarly, when the ankle joint of the human body shows a tendency to evert, the foot of the human body will turn outside the legs relative to the legs, and the foot will drive the second binding structure 13 to turn outward relative to the first binding structure 12. When the evert limiting portion 32 abuts against the first binding structure 12, the second binding structure 13 cannot continue to turn outward, and the evert limiting portion 32 limits the outward turning angle of the second binding structure 13, thereby limiting the outward turning of the foot relative to the leg, thereby avoiding evert of the ankle joint to protect the ankle joint.
[0060] In some embodiments, the inward limiting portion 31 and the outward limiting portion 32 are arranged on the first binding structure 12. Taking the human body in a normal standing posture as a reference state, the inward limiting portion 31 and the second binding structure 13 have a first angle (not shown in the figure), and the first angle provides a limiting stroke for the second binding structure 13 to flip inward compared to the first binding structure 12. The outward limiting portion 32 and the second binding structure 13 have a second angle (not shown in the figure), and the second angle provides a limiting stroke for the second binding structure 13 to flip outward compared to the first binding structure 12. The angle of the first angle is set to be smaller than the angle of the second angle.
[0061] At the same time, the inward limiting portion 31 and the outward limiting portion 32 can also be arranged on the second binding structure 13. Similarly, taking the human body in a normal standing posture as a reference state, the inward limiting portion 31 and the first binding structure 12 have a first angle, and the first angle provides a limiting stroke for the second binding structure 13 to flip inward compared to the first binding structure 12. The outward limiting portion 32 and the first binding structure 12 have a second angle, and the second angle provides a limiting stroke for the second binding structure 13 to flip outward compared to the first binding structure 12. The angle of the first angle is set to be smaller than the angle of the second angle.
[0062] In this embodiment, the adduction limiting portion 31 and the eversion limiting portion 32 are set on the second binding structure 13 as an example for explanation. Since ankle adduction is more common and easy to occur, taking the human body in a normal standing posture as a reference state, the angle of the first angle is set to be smaller than the angle of the second angle. This design is more inclined to quickly prevent the human foot from transitioning inversion. When the human foot is inverted, the first binding structure 12 can be against the adduction limiting portion 31 more quickly, thereby limiting the inversion angle of the second binding structure 13 relative to the first binding structure 12 as soon as possible, which is conducive to limiting the possibility of ankle adduction as much as possible and improving the protection effect.
[0063] Please refer to Figure 3 , which shows that the adduction limiting portion 31 and the eversion limiting portion 32 are arranged on the second binding structure 13, and the human body is in a normal standing posture at this time. At this time, the angle of the first angle is 0° (the adduction limiting portion 31 is completely in contact with the first binding structure 12, so the first angle is 0°), and the angle of the second angle is greater than the angle of the first angle (there is a gap between the eversion limiting portion 32 and the first binding structure 12, and the second angle is not 0°). Of course, in other embodiments, the angle of the first angle can also be designed to be greater than 0°.
[0064] When the human body is in a normal standing posture, the first angle between the inward limiting portion 31 and the first binding structure 12 is set to 0°, that is, in this state, the first binding structure 12 is in contact with the inward limiting portion 31. In this way, the inward turning angle of the second binding structure 13 compared to the first binding structure 12 is basically 0°. When the human body's foot is impacted by external force, the human body's foot basically cannot turn inward, thereby effectively preventing the human body's foot from turning inward and improving the protection effect on the ankle joint.
[0065] See also Figure 7 and Figure 8When the first limiting structure 30 is arranged on the first binding structure 12, the first binding structure 12 forms a limiting end face along the sagittal plane of the human body, and the limiting end face has a connecting transition area 33 and a first limiting surface 311 and a second limiting surface 321 respectively extending to both sides from the connecting transition area 33. The first limiting surface 311 constitutes an adduction limiting portion 31, and the second limiting surface 321 constitutes an eversion limiting portion 32. The second binding structure 13 can be respectively abutted against the first limiting surface 311 and the second limiting surface 321 for limiting. When the second binding structure 13 is abutted against the first limiting surface 311 for limiting, the ankle protector is in an adduction limiting state, thereby limiting the adduction of the ankle joint. When the second binding structure 13 is abutted against the second limiting surface 321 for limiting, the ankle protector is in an eversion limiting state, thereby limiting the eversion of the ankle joint. When the first limiting structure 30 is arranged on the second binding structure 13, the second binding structure 13 forms a limiting end face along the sagittal plane direction of the human body, and the limiting end face has a connecting transition area 33 and a first limiting surface 311 and a second limiting surface 321 respectively extending to both sides from the connecting transition area 33. The first limiting surface 311 constitutes an adduction limiting portion 31, and the second limiting surface 321 constitutes an eversion limiting portion 32. The first binding structure 12 can be abutted against the first limiting surface 311 and the second limiting surface 321 for limiting. When the first binding structure 12 is abutted against the first limiting surface 311 for limiting, the ankle protector is in an adduction limiting state, thereby limiting the adduction of the ankle joint. When the first binding structure 12 is abutted against the second limiting surface 321 for limiting, the ankle protector is in an eversion limiting state, thereby limiting the eversion of the ankle joint.
[0066] In this embodiment, the adduction limiting portion 31 and the eversion limiting portion 32 are provided on the second binding structure 13 as an example for explanation. The design of the limiting end surface allows the first binding structure 12 to achieve surface contact with the first limiting surface 311 or the second limiting surface 321 when the ankle support device is in the adduction limiting state or the eversion limiting state, thereby improving the stability and strength of the first binding structure 12 when it abuts against the adduction limiting portion 31 and the stability and strength of the first binding structure 12 when it abuts against the eversion limiting portion 32. Of course, when the second binding structure 13 and the first binding structure 12 have other active angles, the first binding structure 12 can also achieve point or surface contact with the adduction limiting portion 31 or the eversion limiting portion 32, thereby achieving limiting.
[0067] See also Fig. 9When the ankle support device is worn on a human foot, the first limiting surface 311 is arranged farther away from the sole of the human foot than the second limiting surface 321, and the first limiting surface 311 and the second limiting surface 321 are arranged at an angle. The angle between the first limiting surface 311 and the second limiting surface 321 constitutes a preset angle a for providing the human foot with the freedom to turn outward and inward. The preset angle a provides a range in which the second binding structure 13 can freely flip relative to the first binding structure 12. The determination of the size of the preset angle a needs to meet the following requirements: it is necessary to provide an activity space or activity angle between the first binding structure 12 and the second binding structure 13, so that when the human body moves, the second binding structure 13 can freely flip relative to the first binding structure 12 within a certain range to adapt to the movement posture of the human body, and avoid the first binding structure 12 and the second binding structure 13 from interfering with and hindering the movement of the human body due to the inability to move with each other; it is also necessary to avoid setting the preset angle a too large. Once the preset angle a is set too large, the activity space or angle between the first binding structure 12 and the second binding structure 13 is too large, and it is difficult to prevent the human ankle joint from transitioning outward or inward. Among them, the preset angle a is designed according to actual restriction requirements, such as 180°, 185°, 190°, 195°, 200°, 205°, 210°, 225°, 240°, etc.
[0068] The inward limiting portion 31 and the outward limiting portion 32 are connected by a connecting transition area 33 and are formed on the same limiting end face, which is beneficial to improving the integration of the first limiting structure 30 and making the structure more compact. Of course, the formation of the inward limiting portion 31 and the outward limiting portion 32 is not limited to this. Those skilled in the art can also choose other suitable structures according to the teachings of the present utility model. The purpose of the inward limiting portion 31 and the outward limiting portion 32 is to limit the flipping angle of the first binding structure 12 or the second binding structure 13. Therefore, the inward limiting portion 31 and the outward limiting portion 32 can also be arranged on the flipping path of the first binding structure 12 or the second binding structure 13. Therefore, the inward limiting portion 31 and the outward limiting portion 32 can also be arranged at a longer distance to adapt to actual needs.
[0069] Please also read Fig.10 and Fig.11When the user walks, the ankle joint will plantar flex and / or dorsiflex, and the second binding structure 13 will flip forward or backward relative to the first binding structure 12, so as to adapt to the human body's movement posture, thereby avoiding affecting the user's normal walking. However, when the ankle joint is excessively plantar flexed and / or dorsiflexed, it will also cause damage to the ankle joint. For this reason, in some optional embodiments, a second limiting structure 40 is further provided between the first binding structure 12 and the second binding structure 13. When the ankle protection device is worn on the human foot, the second limiting structure 40 can limit the forward flipping angle and / or backward flipping angle of the second binding structure 13 compared to the first binding structure 12, so as to limit the plantar flexion angle and / or dorsiflexion angle of the ankle joint of the human foot, thereby protecting the ankle joint.
[0070] Please also read Fig.10 and Fig.11 The specific structure of the second limiting structure 40 can be designed according to actual needs. In some optional embodiments, the second limiting structure 40 includes a plantar flexion limiting portion 41 and a dorsiflexion limiting portion 42; the plantar flexion limiting portion 41 and the dorsiflexion limiting portion 42 are arranged on the first binding structure 12 or the second binding structure 13, and the plantar flexion limiting portion 41 and the dorsiflexion limiting portion 42 are respectively used to limit the forward flipping angle and the backward flipping angle of the second binding structure 13 compared with the first binding structure 12. In this embodiment, the plantar flexion limiting portion 41 and the dorsiflexion limiting portion 42 are provided on the second binding structure 13 as an example for explanation. During the walking process of the human body, the foot will flip forward relative to the leg so that when the ankle joint plantar flexion is realized, the foot will drive the second binding structure 13 to flip backward relative to the first binding structure 12, until the plantar flexion limiting portion 41 abuts against the first binding structure 12, and the second binding structure 13 cannot continue to flip backward, thereby realizing that the plantar flexion limiting portion 41 limits the backward flipping angle of the second binding structure 13, thereby avoiding excessive plantar flexion of the ankle joint. Similarly, during the walking process of the human body, the foot will flip forward relative to the leg so that when the ankle joint dorsiflexion is realized, the foot will drive the second binding structure 13 to flip forward relative to the first binding structure 12, until the dorsiflexion limiting portion 42 abuts against the first binding structure 12, and the second binding structure 13 cannot continue to flip forward, thereby realizing that the dorsiflexion limiting portion 42 limits the forward flipping angle of the second binding structure 13, thereby avoiding excessive dorsiflexion of the ankle joint.
[0071] See also Figure 7In some optional embodiments, the plantar flexion limiting portion 41 and the dorsiflexion limiting portion 42 are arranged to protrude from the limiting end surface along the cross-sectional direction of the human body, so as to facilitate the reasonable design of the position arrangement of the first limiting structure 30 and the second limiting structure 40, improve the integration between the first limiting structure 30 and the second limiting structure 40, and make the overall structure more compact. Of course, in other embodiments, the plantar flexion limiting portion 41 and the dorsiflexion limiting portion 42 can also be arranged at other suitable positions. The plantar flexion limiting portion 41 and the dorsiflexion limiting portion 42 are intended to limit the flipping angle of the first binding structure 12 or the second binding structure 13, so they can also be arranged at other positions on the flipping path of the first binding structure 12 or the second binding structure 13, so that the plantar flexion limiting portion 41 and the dorsiflexion limiting portion 42 are spaced far enough apart to adapt to actual needs.
[0072] Continue reading Figure 7 In some optional embodiments, the plantar flexion limiting portion 41 and the dorsiflexion limiting portion 42 are respectively protruded from the two ends of the connection transition area 33 provided on the limiting end surface, so as to facilitate the formation of the plantar flexion limiting portion 41 and the dorsiflexion limiting portion 42 at appropriate positions on the first binding structure 12 and the second binding structure 13, so that the design of the first limiting structure 30 and the second limiting structure 40 is more compact. Among them, the connection transition area 33 can be a smooth transition plane or a transition curved surface. Of course, the connection transition area 33 can also be a folded angle portion. In this embodiment, the connection transition area 33 is a folded angle portion formed between the first limiting surface 311 and the second limiting surface 321. When the second binding structure 13 is flipped relative to the first binding structure 12 until the first binding structure 12 abuts against the plantar flexion limiting portion 41 or the dorsiflexion limiting portion 42, the folded angle portion can prevent the second binding structure 13 and the first binding structure 12 from shaking against each other and improve the position stability between the second binding structure 13 and the first binding structure 12.
[0073] The specific connection method of the first binding structure 12 and the second binding structure 13 can be designed according to actual needs, for example, see Figure 7 In some optional embodiments, the first binding structure 12 and the second binding structure 13 are rotatably connected via a pivot portion 50, and at least a portion of the pivot portion 50 passes through the limiting end surface.
[0074] Among them, in some optional embodiments, the pivoting part 50 is a ball head structure. The ball head structure can improve the flexibility of the first binding structure 12 and the second binding structure 13 in rotating relative to each other, so that the range of the second binding structure 13 flipping relative to the first binding structure 12 can better adapt to the movement posture of the human body. Of course, the pivoting part 50 can also adopt a rotating shaft structure. For example, the pivoting part 50 includes a first rotating shaft, an adapter and a second rotating shaft. The first binding structure 12 rotates with the adapter through the first rotating shaft, and the second binding structure 13 rotates with the adapter through the second rotating shaft. The second binding structure 13 can flip inward or outward relative to the first binding structure 12 through the first rotating shaft, and can flip forward or backward relative to the second binding structure 13 through the second rotating shaft.
[0075] See also Figure 7 In some optional embodiments, the pivot portion 50 at least partially penetrates the transition area 33 of the limiting end surface, and the first limiting surface 311, the second limiting surface 321, the plantar flexion limiting portion 41 and the dorsiflexion limiting portion 42 are all distributed around the outer peripheral side of the pivot portion 50. The plantar flexion limiting portion 41 and the dorsiflexion limiting portion 42 are respectively protruded from the two end portions of the transition area 33 of the limiting end surface, thereby improving the structural integration of the first limiting structure 30 and the second limiting structure 40 and making the structure more streamlined.
[0076] See also Figure 7 In some optional embodiments, when the first limiting surface 311, the second limiting surface 321, the plantar flexion limiting portion 41 and the dorsiflexion limiting portion 42 are all arranged on the first binding structure 12, a groove 14 is provided on the first binding structure 12, and the bottom wall of the groove 14 is arranged along the sagittal plane direction of the human body, the groove 14 has an opening facing downwardly of the human body and a side wall of the groove 14 protruding from the bottom of the groove 14 along the cross-sectional direction of the human body, and the two ends of the side wall of the groove 14 respectively constitute the plantar flexion limiting portion 41 and the dorsiflexion limiting portion 42, the bottom wall of the groove 14 constitutes a limiting end face, the pivot portion 50 passes through the bottom wall of the groove 14, and at least part of the pivot portion 50 is located at the bottom of the groove 14. In the groove 14; when the first limiting surface 311, the second limiting surface 321, the plantar flexion limiting portion 41 and the dorsiflexion limiting portion 42 are all arranged on the second binding structure 13, a groove 14 is provided on the second binding structure 13, the groove bottom wall of the groove 14 is arranged along the sagittal plane of the human body, the groove 14 has an opening facing upwards of the human body and a side wall of the groove 14 protruding from the groove bottom of the groove 14 along the cross-sectional direction of the human body, the two ends of the side wall of the groove 14 respectively constitute the plantar flexion limiting portion 41 and the dorsiflexion limiting portion 42, the groove bottom wall of the groove 14 constitutes a limiting end face, the pivoting portion 50 passes through the groove bottom wall of the groove 14, and at least part of the pivoting portion 50 is located in the groove 14. In this embodiment, the first limiting surface 311, the second limiting surface 321, the plantar flexion limiting portion 41 and the dorsiflexion limiting portion 42 are all arranged on the second binding structure 13 as an example for description.
[0077] In the present embodiment, the specific structures of the first limiting structure 30 and the second limiting structure 40 are respectively constituted by the bottom wall of the groove 14 and the side wall of the groove 14. Since the first limiting structure 30 and the second limiting structure 40 are both formed on the groove 14, the first limiting structure 30 and the second limiting structure 40 are highly integrated to form a whole, and the structure is more compact. At the same time, the groove 14 structure also has a high structural strength, which improves the service life. Furthermore, the pivot part 50 is arranged as a groove bottom wall that partially penetrates the groove 14. Through the structure of the groove 14, the first limiting structure 30, the second limiting structure 40 and the pivot connection structure are cleverly integrated into one, and the first limiting surface 311, the second limiting surface 321, the plantar flexion limiting portion 41 and the dorsiflexion limiting portion 42 are creatively distributed around the outer peripheral side of the pivot part 50. When it is necessary to switch from a single limiting state to a state in which the first limiting structure 30 and the second limiting structure 40 are simultaneously limited, since the pivot part 50 is located at the center of all the limiting structures, the switching is fast and continuous.
[0078] Of course, according to actual needs, the first limiting structure 30 and the second limiting structure 40 can also be arranged in appropriate positions according to the flipping path of the first binding structure 12 or the second binding structure 13 and according to the structure of the first binding structure 12 and the second binding structure 13 to limit the flipping of the first binding structure 12 or the second binding structure 13.
[0079] See also Fig.12 In some optional embodiments, an elastic support lining 22 is provided in the flexible wearable article 20, and the elastic support lining 22 is located on opposite sides of the second wearable space 21, and the elastic support lining 22 is used to limit the inversion angle and / or eversion angle of the ankle joint of the human foot. When the ankle joint is adducted and everted, the elastic support lining 22 can provide a certain auxiliary support force for both sides of the ankle joint, which can avoid the adduction and eversion of the ankle joint, thereby improving the protective effect and buffering effect of the flexible wearable article 20, and is conducive to cooperating with the rigid wearable article to achieve further prevention of ankle sprains. In addition, since the supporting force of the rigid wearable article 10 acts on the ankle joint through the elastic support lining 22, a certain transition is provided, and the elastic support lining 22 disperses the force, which is conducive to reducing the local pressure on the ankle joint and reducing the pressure on the ankle joint. In addition, the elastic support lining 22 has a certain elasticity, can match feet of different sizes, and is not easy to affect the flexibility of the ankle joint. In this embodiment, the flexible wearable article 20 is made of fabric, and the elastic support lining 22 is sewn into the flexible wearable article 20 . Of course, the elastic support lining 22 can also be set at other suitable positions of the flexible wearable article 20 .
[0080] See also Fig.12 The specific structure of the elastic support lining 22 can be designed according to actual needs. For example, in some optional embodiments, the elastic support lining 22 includes an intermediate connecting plate 221 and two elastic plates 222. The intermediate connecting plate 221 is connected between the two elastic plates 222. The intermediate connecting plate 221 and the two elastic plates 222 are both arranged in the flexible wearable component 20. The intermediate connecting plate 221 is arranged at the bottom of the second wearing space 21, and the two elastic plates 222 are respectively arranged on opposite sides of the second wearing space 21. When the ankle joint is adducted and everted, it will be pressed against the elastic plate 222, causing the elastic plate 222 to produce elastic deformation. The elastic force of the elastic plate 222 can provide physical support and buffering for the ankle joint, thereby helping to avoid adduction and eversion of the ankle joint, thereby providing protection for the ankle joint.
[0081] See also Fig.13 In some optional embodiments, a first strap 23 is provided on the outside of the flexible wearable member 20, and the first strap 23 is arranged around the second wearing space 21. At least a portion of the first strap 23 is detachably connected to the flexible wearable member 20, and the first strap 23 binds the flexible wearable member 20 tightly, so that the flexible wearable member 20 is firmly fixed to the user's foot. At least a portion of the first strap 23 is detachably connected to the flexible wearable member 20, so that the flexible wearable member 20 is fixed when the first strap 23 binds the flexible wearable member 20. The manner in which the first strap 23 is detachably connected to the flexible wearable member 20 can be designed according to actual needs. For example, the root of the first strap 23 is fixed to the flexible wearable member 20, and the head end or the portion close to the head end of the first strap 23 is detachably fixed to the flexible wearable member 20 through a Velcro structure, or the head end or the portion close to the head end of the first strap 23 is detachably fixed to the flexible wearable member 20 through a buckle structure.
[0082] See also Fig.13 In some optional embodiments, an elastic cushion 24 is provided at the bottom of the flexible wearable member 20. The elastic cushion 24 provides a cushion for the sole of the user's foot and can absorb the impact energy when the user's foot lands on the ground. High energy absorbing materials can be embedded in the elastic cushion 24, so as to improve the effect of absorbing impact energy. The high energy absorbing materials can be ACF materials, EVA materials, etc.

For example, in some optional embodiments, the first binding structure 12 includes a posture limiting rod 121 and a leg strap 122. The posture limiting rod 121 is made of a rigid material, and the posture limiting rod 121 is rotatably matched with the pivoting portion 50. The leg strap 122 is arranged on the posture limiting rod 121 to bind the posture limiting rod 121 and the legs of the human body together. Of course, the first binding structure 12 can also adopt other suitable structural designs, and is not limited to this example. The second binding structure 13 includes a support plate 131, an inner plate 132 and an outer plate 133, which are all made of rigid materials. The inner plate 132 and the outer plate 133 are respectively arranged on opposite sides of the support plate 131, and the inner plate 132 and the outer plate 133 are connected to each other through a second strap 134. The inner plate 132 and the outer plate 133 cooperate to provide support for the side of the ankle joint. The inner plate 132 is located on the side of the ankle joint facing between the two legs, and the outer plate 133 is located on the side of the ankle joint facing outside the two legs. The support plate 131, the inner plate 132, the outer plate 133 and the second strap 134 surround and form the first wearing space 11, thereby cooperating to limit the ankle joint within the first wearing space 11, and the pivot 50 and the groove 14 are arranged on the outer plate 133. Of course, the second binding structure 13 can also adopt other suitable structural designs, not limited to this example.
