[0002] With the continuous improvement of living standards, people's entertainment activities are increasingly colorful, such as parachuting, skiing, skating and other projects are increasingly favored. However, these activities pose considerable pressure on the ankles of participants, which can easily lead to injuries such as adduction and eversion, and in severe cases, even accidents such as fractures and dislocations. In view of this, wearing an ankle protection device has become an important means for many athletes to protect themselves. Unfortunately, most of the ankle protection devices on the market only use cloth wearing structures, which are not ideal in providing support and limiting ankle movement, and there is a significant problem of inadequate protection. CONTENT OF THE UTILITY MODEL

[0003] The purpose of the embodiment of the present utility model is to provide an ankle protection device that limits the angle of ankle rotation in all directions through a powerful rigid support structure, effectively solving the problem of accidental injury caused by excessive rotation of the ankle under impact.

[0004] To achieve the above purpose, the present application adopts the following technical solutions:

[0005] An ankle protection device is provided, comprising:

[0006] A palm fixing member adapted to be fixed on the palm of the foot;

[0007] A leg fixing member adapted to be fixed on the leg;

[0008] An adapter having two ends each provided with a hinge part, and the rotation axes of the two hinge parts are perpendicular to each other, one of the hinge parts is hinged to the palm fixing member, and the other hinge part is hinged to the leg fixing member; based on the two hinge parts, the leg fixing member can rotate inwards and outwards within a first angle range relative to the palm fixing member, and the leg fixing member can rotate upwards and downwards within a second angle range relative to the palm fixing member.

[0009] Based on the ankle protection device provided by the embodiment, the following beneficial effects can be achieved:

[0010] 1) Significantly improve the protection performance: through the synergistic effect of the palm fixing member, the leg fixing member and the adapter, the excessive rotation of the ankle under impact is effectively limited, thereby significantly reducing the risk of ankle injury. Specifically, the hinge design of the adapter allows movement within a certain range, but beyond this range, it will automatically limit rotation, ensuring that the ankle moves within a safe range.

[0011] 2) The influence on walking is small: the foot can still safely turn over within a certain angle range, avoiding the influence on the normal walking and movement of the user; and the comfort of wearing is ensured.

[0012] 3) The structure is reliable: two hinge parts are arranged at the two ends of the adapter, which are respectively used for hinge connecting the palm part fixing member and the leg part fixing member, that is, two independent hinge points are arranged, each hinge point can only rotate around a fixed shaft within one degree of freedom, and the structure is more reliable.

[0013] Optionally, a first limiting structure is arranged between the adapter and the palm part fixing member or the leg part fixing member, which can limit the inward and outward turning of the leg part fixing member relative to the palm part fixing member within the first angle range; a second limiting structure is arranged between the adapter and the palm part fixing member or the leg part fixing member, which can limit the upward and downward turning of the leg part fixing member relative to the palm part fixing member within the second angle range.

When the elastic member is arranged, the elastic member can make the leg part fixing member self-position to the initial position, at this time, the user can easily put the foot into the leg part fixing member and the palm part fixing member, thereby achieving the effect of convenient wearing. During the use process of wearing, when the palm part fixing member turns relative to the leg part fixing member, the elastic member will deform and store energy, and the process of storing energy will provide a certain resistance, which is equivalent to providing the effect of buffering and shock absorption, which realizes the shock absorption protection of the ankle joint. When the external force disappears, the elastic member releases the stored energy, and drives the palm part fixing member to reset to the initial position or a state close to the initial position, which is equivalent to providing the effect of assistance. Therefore, the arrangement of the elastic member of the present scheme also provides the effects of shock absorption and assistance.

DETAILED DESCRIPTION

[0062] In order to make the technical problems solved by the present application, the technical solutions adopted and the technical effects reached more clear, the technical solutions of the embodiments of the present application are described in further detail below. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0063] In the description of the present application, unless explicitly defined and limited, the terms "connected", "connected", "fixed" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrated; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the internal communication of two elements or the interaction relationship between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0064] In the present application, unless explicitly defined and limited, the first feature "on" or "under" the second feature can include that the first and second features are in direct contact, or that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, the first feature "on", "above" and "above" the second feature includes that the first feature is directly above and obliquely above the second feature, or only indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature "below", "below" and "below" the second feature includes that the first feature is directly below and obliquely below the second feature, or only indicates that the horizontal height of the first feature is less than that of the second feature.

[0065] With the continuous improvement of living standards, people's entertainment activities are increasingly colorful, such as skydiving, skiing, skating and other projects are increasingly favored. However, these activities on the participants ankle constitutes considerable pressure, prone to injury such as adduction valgus, severe even fracture dislocation and other accidents. In view of this, wearing ankle protection device has become an important means of self-protection for many athletes. But unfortunately, when the ankle protection device on the market mostly only use cloth wearing structure, the effect of this structure in providing support and limiting ankle activity is not ideal, there is a significant lack of protection problem.

[0066] Specifically, the existing cloth ankle wearing structure is a flexible structure, which is worn on the foot, can buffer the impact force received at the ankle, thereby reducing ankle injury. However, when the impact received by the foot is too large, the foot will still appear a large angle of rollover, when the rollover exceeds the limit angle, it will directly cause ankle injury.

[0067] In order to overcome the above technical problems, as shown in Figures 1-3 The embodiment provides an ankle protection device, which comprises a palm fixing part 1, a leg fixing part 2 and an adapter 3.

[0068] In the specific structure, referring to Figures 4-5 The palm fixing part 1 is suitable for being fixed on the foot. That is, in use, the palm fixing part 1 can be fixed on the foot, and it should be noted that the palm fixing part 1 of the embodiment is used to be fixed on the foot, and can be directly worn on the foot, or can be worn on the outside of the socks first, and then the palm fixing part 1 is sleeved on the outside of the socks. Or wear shoes on the foot, and then the palm fixing part 1 is sleeved on the outside of the shoes, in other words, the foot fixing part of the embodiment is not limited to be directly sleeved on the foot. Generally, the palm fixing part 1 has a wearing function, so that a wearable accommodating cavity is usually arranged thereon, so as to accommodate the foot or shoes; in order to facilitate wearing, a detachable structure such as elastic band, magic tape, lock buckle and the like is usually arranged.

[0069] Referring to Figure 6 The leg fixing part 2 is suitable for being fixed on the leg. That is, in use, the leg fixing part 2 can be fixed on the leg, generally on the lower leg. Similarly, when wearing, it can be directly worn on the leg, or it can be sleeved on the outside of the trousers on the leg. Generally, the leg fixing part 2 has a wearing function, and an accommodating cavity which can be worn on the leg is usually arranged, and a detachable structure such as elastic band, magic tape, lock buckle and the like is usually arranged for facilitating wearing.

[0070] Referring to Figure 3The adapter 3 is provided with a hinge part 31 at each end, and the rotation axes of the two hinge parts 31 are perpendicular to each other, one of the hinge parts 31 is hinged with the palm part fixing part 1, and the other hinge part 31 is hinged with the leg part fixing part 2; based on the two hinge parts 31, the leg part fixing part 2 can be turned in and out relative to the palm part fixing part 1 within a first angle range, and the leg part fixing part 2 can be turned up and down relative to the palm part fixing part 1 within a second angle range.

[0071] The key of the ankle protection device of the embodiment is to limit the turning angle of the foot when the foot is impacted, so as to avoid the problem of ankle injury caused by too large turning angle of the foot. Therefore, the upper and lower ends of the adapter 3 need to be connected to the leg part fixing part 2 and the palm part fixing part 1 respectively, when the palm part fixing part 1 contacts the ground and is impacted, the impact force can be transmitted to the leg part fixing part 2 through the adapter 3, and the impact force is directly borne by the leg part, thereby avoiding the problem of damage caused by too large impact on the foot.

[0072] During normal walking, the human foot will have the actions of plantar flexion (i.e. the action of pressing the foot downwardly so that the toes are stretched toward the ground), dorsal flexion (i.e. the action of lifting the foot upwardly so that the toes are away from the ground), turning in (i.e. the action of rotating the foot inwardly), and turning out (i.e. the action of rotating the foot outwardly).

[0073] In order to reduce the influence of wearing the protection device on the normal walking of the user as much as possible while maintaining good ankle protection function, the two ends (which can be the upper and lower ends or the upper and lower ends) of the adapter 3 of the scheme are respectively provided with a hinge part 31, and the palm part fixing part 1 and the leg part fixing part 2 are respectively hinged with a hinge part 31, so that the palm part fixing part 1 and the leg part fixing part 2 can be turned in and out and turned up and down relative to each other.

[0074] Specifically, when the foot turns in, the palm part fixing part 1 is turned inwardly relative to the leg part fixing part 2; when the foot turns out, the palm part fixing part 1 is turned outwardly relative to the leg part fixing part 2; when the foot plantar flexes, the palm part fixing part 1 is turned downwardly relative to the leg part fixing part 2; and when the foot dorsal flexes, the palm part fixing part 1 is turned upwardly relative to the leg part fixing part 2. Therefore, the arrangement of the adapter 3 of the scheme realizes the adaptation to the normal activities of the foot during walking of the user, and avoids the problem of influence of the protection device on the normal walking. This also improves the wearing comfort, especially when the palm part fixing part 1 is sleeved outside the shoe device, the effect of non-sensing wearing can be basically obtained.

[0075] In order to provide effective protection, the leg fixing part 2 and the palm fixing part 1 in the scheme can have limited relative turning angles, specifically, the turning inwards and outwards occurs within a first angle range, and the turning upwards and downwards occurs within a second angle range, so that the ankle joint can be prevented from being damaged. When the palm fixing part 1 is turned to the limit value of the first angle range or the second angle range relative to the leg fixing part 2, the palm fixing part 1 will not be able to continue to rotate, thereby avoiding the problem of excessive turning of the foot.

[0076] In the specific structural arrangement, the two hinge parts at the two ends of the adapter 3 have one axis extending in the upwards and downwards direction and the other axis extending in the left and right direction; correspondingly, the hinge part with the axis extending in the upwards and downwards direction can be rotated in the inwards and outwards direction, and the hinge part with the axis extending in the left and right direction can be rotated in the upwards and downwards direction. When the hinge part 31 connected by the palm fixing part 1 is rotated in the inwards and outwards direction, i.e., the palm fixing part 1 can be turned inwards and outwards relative to the adapter 3, the hinge part 31 connected by the leg fixing part 2 is rotated in the upwards and downwards direction, i.e., the leg fixing part 2 can be turned upwards and downwards relative to the adapter 3; when the hinge part 31 connected by the palm fixing part 1 is rotated in the upwards and downwards direction, i.e., the palm fixing part 1 can be turned upwards and downwards relative to the adapter 3, the hinge part 31 connected by the leg fixing part 2 is rotated in the inwards and outwards direction, i.e., the leg fixing part 2 can be turned inwards and outwards relative to the adapter 3.

[0077] In the scheme, two hinge parts 31 are arranged at the two ends of the adapter 3 for hingedly connecting the palm fixing part 1 and the leg fixing part 2, i.e., two independent hinge points are arranged, each hinge point can only rotate around one rotation axis in one rotation degree of freedom, and the structure in the scheme has better reliability compared with the structure with one hinge point (such as the universal ball hinge structure, which can rotate in multiple rotation degrees of freedom).

[0078] Preferably, the two hinge parts 31 at the two ends of the adapter 3 are arranged upwards and downwards, the upper hinge part 31 is connected with the leg fixing part 2, and the leg fixing part 2 can be turned inwards and outwards relative to the adapter 3; the lower hinge part 31 is connected with the palm fixing part 1, and the palm fixing part 1 can be turned upwards and downwards relative to the adapter 3. Arranging the turning-inwards-and-outwards fulcrum above the turning-upwards-and-downwards fulcrum can avoid the problem of pinching the foot of a tall user, and achieve the effect of adapting to more foot types.

[0079] In summary, the ankle protection device provided by the embodiment has at least the following beneficial effects:

[0080] 1) Significantly improve protection performance: through the synergy of palm fixing part 1, leg fixing part 2 and adapter 3, the excessive turning of ankle when impacted is effectively limited, thereby significantly reducing the risk of ankle injury. Specifically, the hinged design of adapter 3 allows movement within a certain range, but beyond this range it will automatically limit turning, ensuring that the ankle moves within a safe range.

[0081] 2) Little impact on walking: the foot wearing the device can still turn within a safe angle range, avoiding the impact on the user's normal walking and movement; at the same time, the comfort of wearing is ensured.

[0082] 3) Good structural reliability: two hinged parts 31 are provided at both ends of the adapter for hinging the palm fixing part 1 and the leg fixing part 2, i.e. a structure with two independent hinge points, each hinge point can only rotate around a fixed axis within one degree of freedom, with better structural reliability.

[0083] In an embodiment, a first limiting structure is provided between the adapter 3 and the palm fixing part 1 or the leg fixing part 2, which can limit the inward and outward turning of the leg fixing part 2 relative to the palm fixing part 1 within the first angle range; a second limiting structure is provided between the adapter 3 and the palm fixing part 1 or the leg fixing part 2, which can limit the upward and downward turning of the leg fixing part 2 relative to the palm fixing part 1 within the second angle range.

[0084] Specifically, when the palm fixing part 1 and the adapter 3 can turn inward and outward relative to each other, the leg fixing part 2 and the adapter 3 can turn upward and downward relative to each other, the first limiting structure is provided between the palm fixing part 1 and the adapter 3, and the second limiting structure is provided between the leg fixing part 2 and the adapter 3. Conversely, when the palm fixing part 1 and the adapter 3 can turn upward and downward relative to each other, the palm fixing part 1 and the adapter 3 can turn inward and outward relative to each other, the first limiting structure is provided between the leg fixing part 2 and the adapter 3, and the second limiting structure is provided between the palm fixing part 1 and the adapter 3.

[0085] As mentioned above, the first limiting structure is used to limit the angle of inward and outward turning, when the palm fixing part 1 tries to turn inward and outward beyond the set first angle range, the first limiting structure will play a role to prevent further turning. The second limiting structure is used to limit the angle of upward and downward turning, when the palm fixing part 1 tries to turn upward and downward beyond the set second angle range, the second limiting structure will play a role to prevent further turning. In specific implementation, the two limiting structures can be achieved through mechanical structures (such as limiting pins, limiting grooves, etc.), and their design purpose is to allow normal movement of the ankle while preventing injury caused by excessive turning.

[0086] By setting the first limiting structure and the second limiting structure, the ankle protection device can more effectively limit the excessive inversion of the ankle, thereby reducing the risk of injury. The two limiting structures work together to provide all-round protection for the ankle.

[0087] In an embodiment, referring to Figure 8 , an elastic member 32 is arranged between the palm fixing member 1 and the adapter 3;

[0088] and / or, an elastic member 32 is arranged between the leg fixing member 2 and the adapter 3;

[0089] The elastic member 32 can provide cushioning and assistance for the inversion of the palm fixing member (1) relative to the leg fixing member (2).

[0090] Specifically, under the action of the elastic member 32, the leg fixing member 2 can be driven to return to the center within the first angle range and / or the second angle range. More specifically, the return to the center of the leg fixing member 2 within the first angle range and the second angle range means that in the normal wearing state and when the user is in the normal standing state, the ankle joint has not been inverted or flexed, the relative position of the leg fixing member 2 and the palm fixing member 1 is the initial position, and returning to this initial position is the return to the center. Of course, in the unworn state, returning to the initial position is also the return to the center.

[0091] When not worn, since the leg fixing member 2 can freely invert and fall relative to the palm fixing member 1 without orientation, this affects the convenience of wearing to some extent. When the elastic member 32 is provided, the elastic member 32 can make the leg fixing member 2 self-position to the initial position, at which time the user can easily put the foot into the leg fixing member 2 and the palm fixing member 1, thereby achieving the effect of convenient wearing.

[0092] Based on the provision of the elastic member 32, during the use in the worn state, when the palm fixing member 1 inverts relative to the leg fixing member 2, the elastic member 32 will deform and store energy, and the process of storing energy will provide a certain resistance, which is equivalent to providing a cushioning effect, which achieves the shock absorption protection of the ankle joint. When the external force disappears, the elastic member 32 releases the stored energy, drives the palm fixing member 1 to return to the center to the initial position or a state close to the initial position, which is equivalent to providing an assistance effect. Therefore, the provision of the elastic member 32 of the present scheme also provides the effects of shock absorption and assistance.

[0093] In an embodiment, the elastic member 32 is a torsional spring, which includes a coil spring portion and a first torsional arm and a second torsional arm connected to both ends of the coil spring portion; the first torsional arm is fixedly connected to the adapter 3, and the second torsional arm is fixedly connected to the palm fixing member 1 or the leg fixing member 2.

[0094] Wherein, the coil spring part is the main part of the torsion spring, responsible for storing and releasing torsional energy; the first torsion arm is fixedly connected to the adapter 3, serving as the connecting point between the torsion spring and the adapter 3; the second torsion arm is fixedly connected to the palm fixing part 1 or the leg fixing part 2, serving as the connecting point between the torsion spring and the fixing part.

[0095] The design of the torsion spring enables it to provide stable torsional force, ensuring that sufficient support and centering reset functions can be provided when the ankle is rolled over, which helps to reduce the risk of injury caused by excessive rolling.

[0096] In one embodiment, referring to Figure 10 , at least one of the hinge parts 31 is provided to include a first rotating shaft 312 and two oppositely arranged first mounting arms 311, the elastic member 32 is arranged between the two first mounting arms 311, the rotating shaft is rotatably penetrated through the two first mounting arms 311 and the coil spring part, and the palm fixing part 1 or the leg fixing part 2 is connected to the rotating shaft.

[0097] In this design, the elastic member 32 is ingeniously arranged between the two first mounting arms 311, and the coil spring part of the torsion spring is rotatably penetrated through the two first mounting arms 311 through the first rotating shaft 312, ensuring that the torsion spring can stably deform and store energy when subjected to force, reducing the risk of deformation or damage caused by uneven force. The first rotating shaft 312 not only penetrates through the two mounting arms and the coil spring part, but also is connected to the palm fixing part 1 or the leg fixing part 2 through appropriate connection methods (such as threaded connection, buckle connection, etc.), which ensures that the hinge part 31 can remain stable when subjected to force, while allowing the palm fixing part 1 or the leg fixing part 2 to rotate relative to the adapter 3.

[0098] In one embodiment, referring to Figure 8 , the end of the hinge part 31 connected to the palm fixing part 1 and / or the leg fixing part 2 is provided with a first slot 221, the first mounting arm 311 and the coil spring part are arranged in the first slot 221, and at least one end of the first rotating shaft 312 is fixedly connected to the material of the side wall of the first slot 221.

[0099] The combination of the first slot 221 and the rotating shaft greatly improves the structural stability of the hinge part 31, the slot design simplifies the installation process, reduces the manufacturing and maintenance costs, and the structure of the entire hinge part 31 is more compact, reducing the occupied space and improving the wearing comfort.

[0100] In an embodiment, one end of the first mounting arm 311 inserted into the first slot 221 is provided with a limiting boss 3111, and a limiting recess is correspondingly arranged on the bottom side of the first slot 221, and the limiting boss 3111 and the limiting recess form the first limiting structure or the second limiting structure.

[0101] The first limiting structure or the second limiting structure (according to design requirements) mainly functions to limit the rotation range of the palm fixing member 1 and / or the leg fixing member 2 relative to the hinge part 31. Specifically, during the rotation of the palm fixing member 1 or the leg fixing member 2 relative to the hinge part 31, the limiting boss 3111 will be deflected in the limiting recess, and when the limiting boss 3111 abuts against the side wall of the limiting recess, it is rotated to the limit, thereby limiting the continuous overturning of the palm fixing member 1. Therefore, by adjusting the shape and size of the limiting boss 3111 and the limiting recess, the rotation range can be accurately controlled, thereby meeting different application requirements.

[0102] The cooperation of the limiting boss 3111 and the limiting recess realizes the control of the value of the first angle range and / or the second angle range, and this structure has the advantages of simplicity and good stability.

[0103] In an embodiment, referring to Figures 11-12 , at least one of the hinge parts 31 is arranged to include a second mounting arm 313 and a second pivot 314, the elastic member 32 is arranged on one side of the second mounting arm 313, the pivot can be rotatably penetrated through the second mounting arm 313 and the coil spring part, and the palm fixing member 1 or the leg fixing member 2 is fixedly connected to the pivot.

[0104] In this embodiment, the elastic member 32 is arranged on one side of the second mounting arm 313, which simplifies the structure and facilitates the assembly of the elastic member 32. In this structure, the hinge is arranged with a second mounting arm 313, and the structure is also simpler and has better assembly convenience.

[0105] In an embodiment, referring to Figure 9 , the end of the palm fixing member 1 and / or the leg fixing member 2 connected to the hinge part 31 is provided with a second slot 121, one side wall of the second slot 121 is further provided with a mounting groove 122, the second mounting arm 313 is arranged in the second slot 121, the elastic member 32 is arranged in the mounting groove 122, and at least one end of the second pivot 314 is fixedly connected to the material of the side wall of the second slot 121.

[0106] The second slot 121 is arranged at the end of the connecting hinge part 31 of the palm fixing part 1 and / or the leg fixing part 2, and is used to receive and fix the second mounting arm 313. A mounting groove 122 is additionally arranged on one side wall of the second slot 121. This design ingeniously utilizes the space of the slot, and provides a special mounting position for the elastic member 32.

[0107] The second mounting arm 313 is arranged in the second slot 121, and tightly matches with the side wall of the slot, thereby ensuring the stability of the structure. The elastic member 32 is arranged in the mounting groove 122. This arrangement not only simplifies the mounting process, but also improves the compactness of the structure.

[0108] In one embodiment, referring to Figure 9 , the slot edge of the second slot 121 forms a limiting edge 1211, and the side wall of the adapter 3 corresponding to the limiting edge 1211 forms a limiting surface. The limiting edge 1211 and the limiting surface cooperate to form the first limiting structure or the second limiting structure.

[0109] The main function of the first limiting structure or the second limiting structure (determined according to design requirements) is to limit the rotation range of the palm fixing part 1 and / or the leg fixing part 2 relative to the hinge part 31. Specifically, during the rotation of the palm fixing part 1 or the leg fixing part 2 relative to the adapter 3, the adapter 3 will be deflected in the second slot 121. When the fiber cotton on the side wall of the adapter 3 abuts against the limiting edge 1211 of the second slot 121, the rotation is limited to the limit, thereby limiting the further turning of the palm fixing part 1. Therefore, by adjusting the shape and size of the second slot 121 and the adapter 3, the rotation range can be accurately controlled, thereby meeting different application requirements.

[0110] This structure directly utilizes the edge of the second slot 121 to limit the rotation of the adapter 3, without the need to set other complex limiting structures, thereby having the advantages of simple structure and low cost.

[0111] In one embodiment, referring to Figure 8 , the mounting groove 122 is a through groove, and a mounting opening corresponding to the through groove is formed on the outer wall of the palm fixing part 1 and / or the leg fixing part 2. The elastic member 32 can be mounted in the mounting groove 122 through the mounting opening. A sealing cover 124 is arranged at the mounting opening.

[0112] The mounting groove 122 is designed as a through groove, which means that it penetrates a part or the whole of the palm fixing part 1 and / or the leg fixing part 2, thereby providing convenience for the mounting of the elastic member 32. A mounting opening corresponding to the through groove is formed on the outer wall of the palm fixing part 1 and / or the leg fixing part 2. This design enables the elastic member 32 to be easily put into the mounting groove 122 through the mounting opening, thereby simplifying the mounting process.

[0113] A sealing cover 124 is additionally arranged at the installation opening. The sealing cover 124 is not only beautiful in design, but more importantly, it can effectively prevent dust, moisture and other external impurities from entering the installation slot 122 and the inside of the elastic member 32, thereby prolonging the service life of the elastic member 32 and maintaining its performance. The sealing cover 124 can be fixed on the installation opening through threaded connection, buckle connection or other appropriate connection methods, to ensure that it is not easy to fall off under stress.

[0114] The above specifically provides two hinge structures and limiting structures. In specific applications, the two hinge parts 31 can simultaneously adopt one of the hinge structures, or can respectively adopt different hinge structures.

[0115] Optionally, the sealing cover 124 and the second rotating shaft 314 are an integral structure, which reduces the number of parts and simplifies the installation process.

[0116] In an embodiment, referring to Figure 6 The leg fixing member 2 includes a leg fixing rod 21 and a first connecting head 22. The first connecting head 22 is connected to the lower end of the leg fixing rod 21. The leg fixing member 2 is hinged to the hinge part 31 through the first connecting head 22.

[0117] The leg fixing rod 21 is the main part of the leg fixing member 2, responsible for fitting and fixing the user's legs. The first connecting head 22 serves as a connecting bridge between the leg fixing rod 21 and the hinge part 31, which not only ensures the stability of the connection, but also provides the necessary flexibility.

[0118] The first connecting head 22 is hinged to the hinge part 31 through appropriate connection methods (such as slot connection, threaded connection, buckle connection, etc.). This hinge design allows the leg fixing member 2 to flip to a certain extent relative to the hinge part 31, thereby adapting to the foot shape and activity needs of different users.

[0119] Optionally, a plurality of weight reduction holes are arranged on the leg fixing rod 21 at intervals. The weight reduction holes can reduce the weight of the leg fixing rod 21 and reduce material consumption.

[0120] Optionally, a first slot 221 is arranged on the bottom side of the first connecting head 22, which is suitable for slot connection with the hinge part 31.

[0121] Optionally, a wearing sleeve is connected to the end of the leg fixing rod 32 away from the first connecting head 22, which can be fixed on the leg.

[0122] In an embodiment, referring to Figures 4-5The palm fixing member 1 includes a palm fixing body 11 and a second connecting head 12, the second connecting head 12 is installed on one side of the palm fixing body 11, and the palm fixing member 1 is hinged with the hinge part 31 through the second connecting head 12.

[0123] The palm fixing body 11 is the main part of the palm fixing member 1, responsible for fixing the user's foot palm. The second connecting head 12 is ingeniously installed on one side of the palm fixing body 11, serving as a connecting bridge between the palm fixing member 1 and the hinge part 31, which not only ensures the stability of the connection, but also provides the necessary flexibility of rotation.

[0124] The second connecting head 12 is stably hinged with the hinge part 31 through precise manufacturing process and connection method (such as slot, thread, buckle, etc.). This hinge design allows the palm fixing member 1 to flip or rotate within a certain range relative to the hinge part 31, thus adapting to the palm shape and activity needs of different users.

[0125] In an embodiment, referring to Figure 9 , the top side of the second connecting head 12 is provided with a second slot 121, and the hinge part 31 extends into the second slot 121 to connect with the second connecting head 12; the bottom side of the second slot 121 is also provided with a sand leakage hole 123.

[0126] The design of the second slot 121 not only provides a stable connection point, but also allows the hinge part 31 to flip or rotate within a certain range, thus enhancing the flexibility and adaptability of the ankle protection device. On the bottom side of the second slot 121, a sand leakage hole 123 is ingeniously added, which is designed to exclude small particles (such as sand, dust, etc.) that may enter the inside of the slot, preventing them from damaging the connection structure or affecting the flexibility.

[0127] In an embodiment, the palm fixing body 11 is provided with a wearing cavity suitable for accommodating the foot palm, and the palm fixing body 11 is also provided with a strap 13 suitable for tightening the palm fixing body 11 on the foot palm.

[0128] The wearing cavity inside the palm fixing body 11 is carefully designed, and its shape, size and position are accurately calculated to ensure perfect fit and accommodation of the user's foot palm. The design of the wearing cavity not only provides a comfortable wearing experience, but also helps to distribute the stress on the foot and reduce the discomfort that may be caused by long-term wearing.

[0129] A strap 13 is ingeniously added on the palm fixing body 11, which is usually made of soft material to ensure that it can provide sufficient fixing force when tightened and will not cause compression to the user's foot. The design of the strap 13 allows the user to freely adjust the tightness of the palm fixing body 11 according to the individual's foot size and comfort needs, so as to ensure that the ankle device can be firmly fixed on the foot.

[0130] In a specific implementation, a lock buckle 14 capable of cooperating with the strap is further arranged on the palm fixing body 11.

[0131] The palm fixing body 11 can be directly worn on the foot or worn on a shoe.

[0132] In an embodiment, the first angle range includes an inward turning angle and an outward turning angle, the inward turning angle is 20°-35°, and the outward turning angle is 10°-25°.

[0133] In a normal wearing state and when the user is in a normal standing state, the ankle joint does not turn or flex, and the relative position of the leg fixing member 2 and the palm fixing member 1 is the initial position. Taking the initial position as 0° reference, the inward turning angle of the palm fixing member 1 relative to the leg fixing member 2 is the inward turning angle, and the outward turning angle of the palm fixing member 1 relative to the leg fixing member 2 is the outward turning angle.

[0134] In a normal case, the inward turning angle of the ankle joint of an adult is about 35°-45°, the inward turning angle of 20°-35° can provide a larger turning space and basically meet the safe turning range of most people. The outward turning angle of the ankle joint of an adult is about 25°-35°, and the outward turning angle of 10°-25° can provide a larger turning space and basically meet the safe turning range of most people.

[0135] In an embodiment, the second angle range includes an upward turning angle and a downward turning angle, the upward turning angle is 10°-20°, and the downward turning angle is 15°-45°.

[0136] In a normal wearing state and when the user is in a normal standing state, the ankle joint does not turn or flex, and the relative position of the leg fixing member 2 and the palm fixing member 1 is the initial position. Taking the initial position as 0° reference, the upward turning angle of the palm fixing member 1 relative to the leg fixing member 2 is the upward turning angle, and the downward turning angle of the palm fixing member 1 relative to the leg fixing member 2 is the downward turning angle.

[0137] Normally, the range of dorsiflexion of the ankle joint of an adult is about 20°, and the upward turning angle of 10°-20° can provide a larger turning space and can basically meet the safe turning range of most people.
