DETAILED DESCRIPTION

[0026] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices consistent with some aspects of the present application as detailed in the appended claims.

[0027] See attached Figure 1-5The present specific embodiment provides an autonomous ankle aid, comprising a base plate 3, a first support member 1 and a second support member 2, wherein the base plate 3 is located on the sole of the foot, the first support member 1 is located below the ankle bone, the second support member 1 is located above the ankle bone, and the first support member 1 and the second support member 2 are in contact with the side of the foot, the first support member 1 is provided with a first elastic member 4 and a first receiving groove, the first receiving groove is used to receive the first elastic member 4, the second support member 2 is provided with a first support rod 5, wherein the bottom end of the first elastic member 4 is fixedly connected to the bottom of the first receiving groove, the bottom end of the first support rod 5 passes through the notch of the first receiving groove and extends into the first receiving groove, and is connected to the top end of the first elastic member 4, so that the first support rod 5 can support the second support member 2.

[0028] During use, when a person walks normally, the first support rod 5 is subjected to force to squeeze the first elastic member 4, and the first elastic member 4 is deformed, which feeds back the upward elastic force to the first support rod 5, thereby preventing the first support rod 5 from descending, so that the first support rod 5 supports the second support member 2, so that the second support member 2 can support the ankle, thereby alleviating the pressure on the ankle.

[0029] Furthermore, the first support member 1 and the second support member 2 can protect the ankle and prevent the ankle from being sprained.

[0030] It should be noted that the first accommodating groove extends in the vertical direction. Here, the first accommodating groove can be a cylindrical groove. The axis of the first elastic member 4 is located on the same straight line as the axis of the first accommodating groove, and the diameter of the first elastic member 4 is smaller than the diameter of the first accommodating groove, so as to facilitate the expansion and contraction of the first elastic member 4 in the first accommodating groove.

[0031] This arrangement solves the problem that the ankle bone needs to support the entire weight of the part above the ankle and is easily sprained, making it impossible for people to walk normally.

[0032] In this embodiment, the first support rod 5 and the first elastic member 4 are connected by an axial connecting member, and the width of the axial connecting member is greater than the width of the notch of the first accommodating groove and smaller than the width of the first accommodating groove. In this way, the connection between the first support rod 5 and the first elastic member 4 is strengthened, and a certain pulling effect is exerted on the first support member 1, and the top end of the first elastic member 4 can be prevented from escaping from the notch of the first accommodating groove, and the bottom end of the first support rod 5 can be prevented from escaping from the first accommodating groove.

[0033] Furthermore, if Figure 2 As shown, the axial connecting member 6 includes a first S buckle 10 and a second S buckle 11. The first S buckle 10 is connected to the top end of the first elastic member 4, and the second S buckle 11 is connected to the bottom end of the first support rod 5. The first S buckle 10 and the second S buckle 11 are in contact and buckled.

[0034] Among them, the first S buckle 10 and the second S buckle 11 have the same structure, and the first S buckle 10 and the second S buckle 11 are both hemispherical structures, and both include a spherical surface and a plane, and a protrusion and a groove are arranged on the plane, and the protrusion and the groove are connected to form an S-shaped surface, and the planes of the first S buckle 10 and the second S buckle 11 are in contact, and the protrusion of the first S buckle 10 is embedded in the groove of the second S buckle 11, and the protrusion of the second S buckle 11 is embedded in the groove of the first S buckle 10. In this way, it is convenient to achieve the docking of the first S buckle 10 and the second S buckle 11.

[0035] It should be noted that if Figure 2 As shown, an elastic pad 12 is provided between the first S buckle 10 and the second S buckle 11 to avoid noise when the first S buckle 10 and the second S buckle 11 rotate relative to each other, and has a buffering effect on the first S buckle 10 and the second S buckle 11 to prevent hard contact between them and increase their service life. The material of the elastic pad 12 can be silicone or rubber, which can be determined according to actual conditions.

[0036] In particular, the first S buckle 10 and the second S buckle 11 can rotate relative to each other so that the first support rod 5 is force-displaced, thereby avoiding limiting the flexibility of the ankle joint and making it easier for the user to turn his legs while walking.

[0037] In order to facilitate the first support rod 5 to deflect and avoid limiting the flexibility of the ankle joint, Figure 3 As shown, two notches 9 are provided on the groove wall at the top of the first accommodating groove, and the two notches 9 are respectively located on the groove walls opposite to each other in the first accommodating groove, and the two notches 9 are distributed along the direction of the foot length, that is, the line connecting the two notches 9 is parallel to the direction of the foot length, so as to facilitate the first support rod 5 to be shifted forward and backward under force.

[0038] When pedaling, the angle between the foot and the leg is less than 90 degrees, that is, the body tends to lean forward, and the first support rod 5 is subjected to force with the axial connector 6 as the axis. When it deviates forward, the second S buckle 11 rotates relative to the first S buckle 10, and rotates forward with the connection point of the first S buckle 10 and the second S buckle 11 near the toe as the axis; when turning back, the angle between the foot and the leg is greater than 90 degrees, that is, the body tends to lean backward, and the first support rod 5 is subjected to force to deviate backward and forward, and rotates backward with the connection point of the first S buckle 10 and the second S buckle 11 near the heel as the axis. In this way, the first support rod 5 can achieve slight deviation according to the movement of the ankle joint, thereby ensuring the flexibility of the ankle joint and not causing damage to the ankle, in accordance with the bionic design.

[0039] It should be noted that the maximum range of the displacement of the first support rod 5 is from the first support rod 5 resting on the notch 9 close to the toes to the first support rod 5 resting on the notch 9 close to the heel.

[0040] In the preferred embodiment of this embodiment, Figure 1As shown, the first support member 1 is also provided with a second elastic member 7 and a second accommodating groove, and the second support member 2 is also provided with a second support rod 8. The bottom end of the second elastic member 7 is fixedly connected to the bottom of the second accommodating groove, the top end of the second elastic member 7 is located in the second accommodating groove, and the bottom end of the second support rod 8 passes through the notch of the second accommodating groove and extends into the second accommodating groove, and is connected to the top end of the second elastic member 7, so that the second support rod 8 can support the second support member 2.

[0041] During use, when a person walks normally, the second support rod 8 is subjected to force to squeeze the second elastic member 7, and the second elastic member 7 is deformed, which feeds back the upward elastic force to the second support rod 8, thereby preventing the second support rod 7 from descending, so that the second support rod 8 supports the second support member 2, so that the second support member 2 can support the ankle, thereby relieving the pressure on the ankle.

[0042] It should be noted that the second accommodating groove extends in the vertical direction. Here, the second accommodating groove can be a cylindrical groove. The axis of the second elastic member 7 is located on the same straight line as the axis of the second accommodating groove, and the diameter of the second elastic member 7 is smaller than the diameter of the second accommodating groove, so that the second elastic member 7 can extend and retract in the second accommodating groove.

[0043] Among them, the second support rod 8 and the second elastic member 7 are connected by an axial connecting member, and the width of the axial connecting member is greater than the width of the notch of the second accommodating groove and smaller than the width of the second accommodating groove. In this way, the connection between the second support rod 8 and the second elastic member 7 is strengthened, and a certain pulling effect is exerted on the second support member 8, and the top end of the second elastic member 7 can be prevented from escaping from the notch of the second accommodating groove, and the bottom end of the second support rod 8 can be prevented from escaping from the second accommodating groove.

[0044] In order to support and protect the ankle joint and relieve the pain of the heel when turning the foot back, the first receiving groove is set at the front side below the ankle bone and close to the toes, and the second receiving groove is set at the back side below the ankle bone and close to the heel. Both the first receiving groove and the second receiving groove are set close to the ankle bone to clamp the ankle bone between the first receiving groove and the second receiving groove.

[0045] Furthermore, the positions of the first elastic member 4 and the first support rod 5 , the second elastic member 7 and the second support rod 8 can be known from the positions of the first receiving groove and the second receiving groove.

[0046] The first support rod 5, the first elastic member 4, the second support rod 8 and the second elastic member 7 are used in combination to further improve the support for the ankle and further relieve the pressure on the ankle. The second support rod 8 and the second elastic member 7 can cooperate to relieve heel pain.

[0047] Depend on Figure 1As shown, the first accommodating groove and the second accommodating groove are higher than the first supporting member 1 , so that the first supporting rod 5 and the second supporting rod 8 are offset and the first supporting member 1 is prevented from causing obstruction to the first supporting rod 5 and the second supporting rod 8 .

[0048] It should be noted that if Figure 1 As shown, the second support member 2 is provided with two accommodating cavities for accommodating the first support rod 5 and the second support rod 8 respectively, the first support rod 5 and the second support rod 8 are respectively located in the two accommodating cavities, and the top ends are fixed to the bottoms of the accommodating cavities, and the bottom ends extend through the cavity openings into the first accommodating groove and the second accommodating groove respectively, wherein the bottoms of the two accommodating cavities are provided with iron sheets for fixing the top ends of the first support rod 5 and the second support rod 8, and magnets can be provided at the top ends of the first support rod 5 and the second support rod 8 to fix the first support rod 5 and the second support rod 8 in the two accommodating cavities, and the top ends of the first support rod 5 and the second support rod 8 can also be fixed to the bottoms of the two accommodating cavities by screws.

[0049] Moreover, the groove width of the two accommodating cavities gradually increases from top to bottom so that the first support rod 5 and the second support rod 8 can be offset in the accommodating groove. In order to facilitate the first support rod 5 or the second support rod 8 to rotate in the accommodating cavity, the top end of the first support rod 5 or the second support rod 8 can be rotatably connected to the bottom of the accommodating cavity, and the top end of the first support rod 5 or the second support rod 8 can be hinged to the bottom of the accommodating cavity.

[0050] Among them, Figure 1 As shown, the first support member 1 and the second support member 2 are both provided with U-shaped grooves near the ankle bone, and the U-shaped groove of the first support member 1 and the U-shaped groove of the second support member 2 are connected to form a cavity that can accommodate the ankle bone, so that it is convenient to position the first support member 1 and the second support member 2 and prevent the first support member 1 and the second support member 2 from being misaligned due to force.

[0051] In this embodiment, two first support members 1 and two second support members 2 are provided, and the two first support members 1 and the two second support members 2 are respectively located on the inner side and the outer side of the foot. In this way, the ankle bones on the inner side and the outer side of the foot can be supported respectively, thereby strengthening the support for the ankle bones and further alleviating the pressure on the ankle joint.

[0052] It should be noted that the two first support members 1 are both connected to the base plate 3 , and the two first support members 1 and the base plate 3 are an integrated structure, which is convenient for wearing and convenient for supporting the first support rod 5 and the second support rod 8 .

[0053] The two first support members 1 are each provided with a first accommodating groove and a second accommodating groove; the two second support members 2 are each connected to the two first support members 1 through a first support rod 5 and a second support rod 8, that is, two first support rods 5 and two second support rods 8 are also provided, and the two first support rods 5 and the second support rods 8 are respectively extended into the two first accommodating grooves and the second accommodating grooves and are connected with the two first elastic members 4 and the second elastic members 7 through an axial connecting member 6.

[0054] like Figure 4 and Figure 5 As shown, in order to fix the two first support members 1 and the two second support members 2 on the foot, the front ends of the two first support members 1 and the two second support members 2 are detachably connected via connecting buckles 14 and the rear ends are connected via connecting belts 13 .

[0055] Among them, the front ends of the two first support members 1 and the two second support members 2 are detachably connected, which is convenient for wearing the autonomous ankle aid, and can be connected by a connecting buckle 14. Here, the connecting buckle 14 can be a snap buckle or a buckle. It is also possible to respectively set a cloth belt on one of the first support members 1 and the second support member 2, and set a plurality of buckle gates spaced apart on the cloth belt, and respectively set buttons on the other first support member 1 and the second support member 2, and connect the two first support members 1 and the second support member 2 through the buttons; of course, they can also be connected by Velcro. Here, the specific connection method is not limited and can be set according to actual conditions. The above-mentioned connecting belt 13 can be an elastic band to facilitate the use of users with different foot widths, thereby improving the versatility of the autonomous ankle aid.

[0056] In order to prevent the first support member 1 and the second support member 2 from causing damage to the foot, soft bags are provided at the contact positions of the first support member 1 and the second support member 2, so that the contact parts of the first support member 1 and the second support member 2 with the foot are soft, thereby preventing the foot from being scratched or bruised.

[0057] In order to increase the air permeability of the autonomous ankle aid and prevent the foot from being covered, the first support member 1 is configured as a hollow structure, or a plurality of air holes are provided on the first support member 1 .

[0058] The soft bag here can be a sponge, or can be soft silicone, or other softer materials.

[0059] In order to increase the comfort of the soles of the feet, a nylon pad is provided on the bottom plate 3 to prevent the user's feet from being hurt while walking, thereby increasing the pain in the feet.

[0060] In this embodiment, an elastic band is also provided between the first support member 1 and the second support member 2, and the elastic band is provided on the inner side of the first support rod 5 and the second support rod 8 to prevent the first support rod 5 and the second support rod 8 from contacting the skin and thereby abrading the skin.
