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 1-5 The present specific embodiment provides an intelligent ankle aid, including 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 linear actuator 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 linear actuator 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 linear actuator 5 can support the second support member 2.

[0028] In addition, a first sensor is arranged on the base plate 3, and the first sensor is communicatively connected to the first linear actuator 5. When the first sensor senses the pressure on the sole of the foot, it can transmit the pressure signal to the first linear actuator 5, and the push rod of the first linear actuator 5 extends to squeeze the first elastic member 4, so that the first elastic member 4 is compressed and deformed, thereby giving the first linear actuator 5 an upward elastic force, so that the push rod cannot continue to extend, so that the first linear actuator 5 can support the second support member 2, and the second support member 2 supports the ankle, thereby relieving 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 sensor can be set on the side of the base plate 3 that contacts the sole of the foot, and of course can also be set on the side away from the sole of the foot. It only needs to be able to sense the pressure of the sole of the foot, and can be set specifically according to actual conditions.

[0031] Here, the first sensor may be a pressure sensor, and the first linear actuator 5 may be an electric push rod or an electric screw push rod.

[0032] The electric push rod is a new type of electric actuator. The electric push rod is a new type of linear actuator mainly composed of a motor, a push rod and a control device, which can achieve remote control and centralized control.

[0033] The electric screw push rod can be composed of a motor and two inner and outer sleeves, the inner and outer sleeves are respectively provided with external threads and internal threads, and the inner sleeve and the outer sleeve can rotate relative to each other. The motor is fixedly mounted on the second support member, and the outer sleeve is mounted on the driving shaft of the motor so that it can rotate with the motor. The inner sleeve is arranged in the outer sleeve, which is equivalent to a push rod and can rotate and retract with the rotation of the outer sleeve. The bottom end of the inner sleeve is connected to the first elastic member 4 to achieve compression of the first elastic member 4, thereby relieving the pressure on the ankle.

[0034] The above motors can all be configured as micro digital motors to reduce the volume of the first linear actuator 5 .

[0035] Among them, 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 that the first elastic member 4 can expand and contract in the first accommodating groove.

[0036] During use, when a person walks normally, the first sensor senses the pressure on the sole of the foot and transmits the pressure signal to the first linear actuator 5. The push rod of the first linear actuator 5 extends out to squeeze the first elastic member 4. The first elastic member 4 prevents the push rod of the first linear actuator 5 from continuing to extend, so that the second support member 2 can support the ankle, thereby alleviating the pressure on the ankle; when the foot is lifted, when the pressure sensed by the first sensor disappears, the push rod of the first linear actuator 5 retracts to the initial position, so that the push rod can be extended to support the ankle next time.

[0037] 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.

[0038] Preferably, in order to improve the sensitivity of the intelligent ankle aid and avoid the first sensor failing to sense pressure when the foot lands on the ground, thereby causing the intelligent ankle aid to lose its function, a second sensor is arranged on the side of the first support member 1 that contacts the foot, and the second sensor is communicatively connected to the first linear actuator 5. The second sensor is located on the front side of the ankle bone and is arranged close to the ankle bone to facilitate sensing the movement of the ankle, thereby being able to quickly transmit the signal to the first linear actuator 5, so that the first linear actuator 5 can be operated. The first sensor and the second sensor act simultaneously, thereby improving the sensitivity of the intelligent ankle aid.

[0039] In this embodiment, the first linear actuator 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 linear actuator 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 linear actuator 5 can be prevented from escaping from the first accommodating groove.

[0040] 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 linear actuator 5. The first S buckle 10 and the second S buckle 11 are in contact and buckled.

[0041] 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.

[0042] 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.

[0043] In particular, the first S buckle 10 and the second S buckle 11 can rotate relative to each other so that the first linear actuator 5 is force-displaced, thereby avoiding limiting the flexibility of the ankle joint and making it easier for the user to turn his leg during walking.

[0044] In order to facilitate the displacement of the first linear actuator 5 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 linear actuator 5 to be displaced forward and backward under force.

[0045] 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 linear actuator 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 linear actuator 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 linear actuator 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.

[0046] It should be noted that the maximum range of the displacement of the first linear actuator 5 is from the time when the first linear actuator 5 abuts against the notch 9 close to the toe to the time when the first linear actuator 5 abuts against the notch 9 close to the heel.

[0047] In the preferred embodiment of this embodiment, Figure 1 As shown, the first support member 1 is also provided with a second elastic member 7 and a second receiving groove, and the second support member 2 is also provided with a second linear actuator 8. The bottom end of the second elastic member 7 is fixedly connected to the bottom of the second receiving groove, the top end of the second elastic member 7 is located in the second receiving groove, and the bottom end of the second linear actuator 8 passes through the notch of the second receiving groove and extends into the second receiving groove, and is connected to the top end of the second elastic member 7, so that the second linear actuator 8 can support the second support member 2.

[0048] During use, when a person is walking normally, the second linear actuator 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 linear actuator 8, thereby preventing the second linear actuator 7 from descending, so that the second linear actuator 8 supports the second support member 2, so that the second support member 2 can support the ankle, thereby alleviating the pressure on the ankle.

[0049] 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.

[0050] Among them, the second linear actuator 8 and the second elastic member 7 are connected through 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 linear actuator 8 and the second elastic member 7 is strengthened, and a certain pulling effect is exerted on the second support member 2, 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 linear actuator 8 can be prevented from escaping from the second accommodating groove.

[0051] 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.

[0052] Furthermore, the positions of the first elastic member 4 and the first linear actuator 5 , the second elastic member 7 and the second linear actuator 8 can be known from the positions of the first receiving groove and the second receiving groove.

[0053] The first linear actuator 5, the first elastic member 4, the second linear actuator 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 linear actuator 8 and the second elastic member 7 are used in combination to relieve heel pain.

[0054] The second linear actuator 8 is communicatively connected to both the first sensor and the second sensor.

[0055] It should be noted that the structure of the second linear actuator is the same as that of the first linear actuator, and according to the foot structure, the length of the push rod of the second linear actuator 8 can be made smaller than the length of the push rod of the first linear actuator 5 to facilitate support for the ankle.

[0056] Depend on Figure 1 As shown, the first accommodating groove and the second accommodating groove are higher than the first supporting member 1 , so that the first linear actuator 5 and the second linear actuator 8 are offset and the first supporting member 1 is prevented from causing obstruction to the first linear actuator 5 and the second linear actuator 8 .

[0057] It should be noted that if Figure 1As shown, the second support member 2 is provided with two accommodating cavities for accommodating the first linear actuator 5 and the second linear actuator 8 respectively. The first linear actuator 5 and the second linear actuator 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 pass through the accommodating cavities and extend 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 tops of the first linear actuator 5 and the second linear actuator 8, and magnets can be provided at the tops of the first linear actuator 5 and the second linear actuator 8 to fix the first linear actuator 5 and the second linear actuator 8 in the two accommodating cavities, and the tops of the first linear actuator 5 and the second linear actuator 8 can also be fixed to the bottoms of the two accommodating cavities by screws.

[0058] Furthermore, the groove width of the two accommodating chambers gradually increases from top to bottom so that the first linear actuator 5 and the second linear actuator 8 can be offset in the accommodating chamber. In order to facilitate the first linear actuator 5 or the second linear actuator 8 to rotate in the accommodating chamber, the top end of the first linear actuator 5 or the second linear actuator 8 can be rotatably connected to the bottom of the accommodating chamber, and the top end of the first linear actuator 5 or the second linear actuator 8 can be hinged to the bottom of the accommodating chamber.

[0059] 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.

[0060] Furthermore, the intelligent ankle aid includes a controller and a battery, both of which are installed on the back side of the heel. The controller is electrically connected to the first sensor, the second sensor, the first linear actuator 5 and the second linear actuator 8, so that the battery can power the first sensor, the second sensor, the first linear actuator 5 and the second linear actuator 8 to enable them to work normally. After the first sensor and the second sensor sense pressure, the pressure signal is converted into an electrical signal and transmitted to the controller, and the controller controls the action of the first linear actuator 5 and the second linear actuator 8.

[0061] Here, the controller may be a control circuit, and a plurality of electrical components and a control chip are arranged on the control circuit. The control chip may be a single-chip chip or an integrated chip, which is not specifically limited, and the electrical components and the control chip may be patch components to reduce the volume. The battery may be a button battery to reduce the volume of the intelligent ankle aid.

[0062] The intelligent ankle aid is also provided with a control switch, which is arranged on the back side of the heel and is electrically connected to the controller to start the intelligent ankle aid. Of course, the start of the intelligent ankle aid can also be controlled by a mobile terminal APP. The mobile terminal APP is communicatively connected to the controller and can control the rotation speed of the motor inside the first linear actuator 5 and the second linear actuator 8, thereby controlling the speed of extension and retraction of the push rod.

[0063] 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.

[0064] 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 linear actuator 5 and the second linear actuator 8 .

[0065] 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 linear actuator 5 and a second linear actuator 8, that is, two first linear actuators 5 and second linear actuators 8 are also provided, and the two first linear actuators 5 and second linear actuators 8 are respectively extended into the two first accommodating grooves and the second accommodating grooves and are connected to the two first elastic members 4 and the second elastic members 7 through an axial connecting member 6.

[0066] 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 .

[0067] 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 intelligent 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 intelligent ankle aid.

[0068] 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.

[0069] In order to increase the air permeability of the intelligent 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 .

[0070] The soft bag here can be sponge, or can be soft silicone, or other softer materials.

[0071] 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.

[0072] In this embodiment, an elastic band is further 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 linear actuator 5 and the second linear actuator 8 to prevent the first linear actuator 5 and the second linear actuator 8 from contacting the skin and thereby abrading the skin.

[0073] In this embodiment, the first elastic member 4 and the second elastic member 7 may be springs, and the pressure index value of the springs is low, such as a pressure index value of 0.5-0.8.

[0074] It should be noted that the words “first”, “second”, etc. described in this article do not limit the specific order, but are merely used to distinguish between various components or functions.
