[0023] As Figures 1 - 9As shown in the figure, this embodiment provides an ankle care device for preventing muscle stiffness, including a foot pad 1 and a strap 6. Inside the foot pad 1, a plurality of ventilation holes 2 are evenly distributed to ensure good air permeability of the user's foot during use, avoiding discomfort caused by stuffiness. On both outer sides of the foot pad 1, side blocks 3 are fixedly connected. The material of the side blocks 3 has a certain flexibility. A dorsal foot strap 4 is connected between the inner sides of the two side blocks 3. The inner side of the dorsal foot strap 4 is made of a soft and skin-friendly material to reduce friction on the dorsal skin of the foot. A female buckle 5 is fixedly connected to the top of the dorsal foot strap 4, which matches the male buckle 8. When the two are buckled, they can provide a stable connection to ensure that the strap 6 is fixed in place. A connecting strap 7 is fixedly connected to the outer front side of the strap 6, and a male buckle 8 is fixedly connected to the front end of the connecting strap 7. A card slot that fits with the top of the female buckle 5 is provided at the bottom of the male buckle 8, and a stable connection is achieved through buckling. The bottom of the male buckle 8 is buckled with the top of the female buckle 5. A lifting mechanism is arranged on the outer side of the strap 6. The lifting mechanism is used to exercise the foot muscles. The lifting mechanism includes a storage box 11 and a front block 9. The outer side of the storage box 11 is fixedly connected to the outer front side of the strap 6. The internal space of the storage box 11 is reasonably designed to just accommodate the micro motor 12 and its winding rod. The micro motor 12 is installed on the outer side of the storage box 11, and its output end is coaxially fixedly connected to the winding rod to ensure that the winding rod can be stably driven to rotate when starting. One end of the front block 9 is fixedly connected to the outer front side of the foot pad 1. A through groove is provided on the front block 9. A convex part made of rubber is fixedly provided at the front end of the winding belt 10. A "T"-shaped structure is formed between the convex part and the winding belt 10. The convex part is embedded through the through groove and clamped on the outer bottom of the front block 9, facilitating the detachable connection of the winding belt 10. A winding belt 10 is detachably connected to the inner side of the front block 9. The rear end of the winding belt 10 enters the inside of the storage box 11 along the opening provided on the storage box 11 and is fixedly connected to the winding rod at the output end of the micro motor 12. Two assembly blocks 13 are fixedly connected to both the left and right outer sides of the strap 6. The assembly blocks 13 are on the outer side of the strap 6 to ensure that after the connecting block 14 is connected, the position of the installation box 15 can cooperate with the foot movement. A connecting block 14 is detachably connected to the outer side of each assembly block 13. One end of the connecting block 14 is connected to the assembly block 13 in a detachable manner such as by a buckle or thread, and the other end is fixedly connected to an installation box 15. The internal space layout of the installation box 15 is reasonable, providing sufficient space for the micro motor 16 and other components. A connecting block 14 is fixedly connected to one end of each of the connecting blocks 14, and a passive exercise mechanism is arranged inside each of the installation boxes 15. The passive exercise mechanisms all include a micro motor 16 and a combination component. The micro motor 16 is installed at the central position inside each installation box 15, and its output end is fixedly connected to a cylindrical gear 17. The meshing accuracy with the cylindrical gear 18 is high, ensuring stable power transmission. A cylindrical gear 18 is rotatably connected inside each installation box 15. A rotating column 19 is fixedly connected to the outer end side of the cylindrical gear 18, which rotates flexibly on the rotating shaft inside the installation box 15. The cylindrical gear 18 meshes with the cylindrical gear 17,The outer part of the rotating column 19 is fixedly connected with a rotating rod 20. The sliding grooves inside the rotating rod 20 are all matched with the sliding rod 22. The sliding rod 22 is slidably connected inside the rotating rod 20. The rear end of the sliding rod 22 is fixedly connected with a spring 21, which has a certain pre-tightening force in the initial state and can ensure the stability of the sliding rod 22 during the movement. The rear end of the sliding rod 22 is fixedly connected with a spring 21, and the rear end of the spring 21 is fixedly connected with the inner rear end of the rotating rod 20. The combined component includes a fitting sleeve 23, which is arranged outside the side block 3. The combined sleeve 24 fixedly connected to the inner side thereof has an inner diameter adapted to the outer diameter of the sliding rod 22 to ensure that the sliding rod 22 can slide smoothly on the inner wall of the combined sleeve 24. The combined sleeve 24 is fixedly connected to the inner side of the fitting sleeve 23, and the outer side of the front section of the sliding rod 22 is slidably connected to the inner wall of the combined sleeve 24.,

[0024] An electrostimulation mechanism is arranged outside the two mounting boxes 15. The electrostimulation mechanism includes a plurality of electrode plates 25 and wires 26. The plurality of electrode plates 25 are evenly distributed outside the mounting boxes 15 and are connected in series or in parallel through the wires 26. The wires 26 have good flexibility and insulation. The electrode plates 25 are made of a soft material with good electrical conductivity and can closely fit the skin of the user's foot to ensure the electrostimulation effect. The plurality of electrode plates 25 are connected through the wires 26, and the electrode plates 25 are attached to the user's foot. A power source and a variety of sensors are arranged inside the mounting box 15. The power source can provide stable power support for the first micro-motor 12, the second micro-motor 16, and the electrostimulation mechanism, etc. The variety of sensors can monitor data such as the movement state and muscle reaction of the user's foot in real time so as to adjust the working mode of the nursing device according to the actual situation.

[0025] Specifically, put the foot pad 1 on the user's foot so that its top closely fits the sole of the foot. The multiple ventilation holes 2 evenly distributed inside the foot pad 1 can continuously provide good breathability for the foot, effectively avoiding discomfort such as sultriness and dampness caused by long-term wrapping, creating a dry and comfortable environment for the foot. At the same time, put the instep strap 4 on the instep. The soft and skin-friendly material on its inner side can gently contact the instep skin, greatly reducing friction and the irritation to the skin, ensuring the comfort of the user when wearing. Wrap the strap 6 around the ankle and fix it with Velcro. The design of the strap 6 can be flexibly adjusted according to the thickness of different users' ankles to ensure a stable and appropriate binding force on the ankle, which can not only ensure the device is firmly worn but also not cause excessive pressure on the ankle. Stretch the connecting strap 7 and precisely fasten the sub-button 8 to the mother button 5. In this way, the stability of the entire device is further strengthened, making the foot pad 1, the instep strap 4, and the strap 6 closely combined as a whole and firmly fixed on the user's foot to avoid displacement or falling off during use. After wearing, stretch the front end of the winding strap 10 and connect it to the front block 9. Start the first micro-motor 12. The winding rod at the output end of the first micro-motor 12 starts to rotate, and then the winding strap 10 is wound. As the winding strap 10 is gradually wound, it will generate an upward pulling force on the foot, driving the foot to slowly lift. Then, let the sole of the foot naturally drop, and repeat this process. During this process, the muscles of the foot will continuously contract and relax, thus realizing mild training of the foot muscles, effectively enhancing the strength and flexibility of the foot muscles, promoting blood circulation in the foot, and laying a foundation for subsequent more in-depth rehabilitation training. When more targeted exercises are needed, the connecting block 14 can be assembled with the assembly block 13. The connecting block 14 and the assembly block 13 are connected by detachable methods such as snap or thread. This design not only facilitates the installation and disassembly of the device but also ensures the stability of the connection. After assembly, insert one end of the sliding rod 22 into the combination sleeve 24 to ensure a tight fit between the two. Then, start the second micro-motor 16. The cylindrical gear one 17 at the output end of the second micro-motor 16 starts to rotate. Due to the high-precision meshing of the cylindrical gear one 17 and the cylindrical gear two 18, the cylindrical gear two 18 rotates accordingly, and then drives the rotating column 19 to rotate. The rotating rod 20 fixedly connected to the outside of the rotating column 19 will rotate with the rotating column 19. During the rotation of the rotating rod 20, the sliding rod 22 inside the rotating rod 20 transfers the force to the foot pad 1 through the cooperation with the combination sleeve 24. Under the action of this force, the foot pad 1 drives the sole of the foot to perform dorsiflexion movement. Through this repeated dorsiflexion movement, the foot joints can be effectively moved, the range of joint movement can be increased, muscle atrophy and joint stiffness can be prevented, and it has a significant effect on improving the motor function of the foot. Among the various sensors set inside the installation box 15, the electromyography sensor plays a key role. It can real-time monitor the activity of the user's foot muscles. Through the precise acquisition and analysis of muscle electrical signals,Obtain real-time status information of the muscles. Based on these monitoring data, the nursing device can automatically adjust the electric stimulation intensity and movement amplitude. When the electromyogram sensor detects low muscle activity, it automatically increases the electric stimulation intensity to stimulate muscle activity; when the muscle activity is too high, it appropriately reduces the electric stimulation intensity to avoid muscle over-fatigue. At the same time, according to the muscle response, the movement amplitude is reasonably adjusted to ensure the maximization of the exercise effect. Considering the daily life needs of patients, the nursing device adopts a time-sharing nursing mode. During the day, when human activities are relatively frequent, electric stimulation is mainly used. Multiple electrode plates 25 in the electric stimulation mechanism are connected by wires 26, evenly distributed outside the installation box 15 and closely attached to the user's foot. These electrode plates 25 are made of soft and good-conducting materials, which can electrically stimulate the foot muscles without affecting the normal activities of patients, promote muscle contraction and relaxation, and improve muscle vitality. At night, when the patient is in a resting state, mechanical movement is mainly used. Through the coordinated work of the lifting mechanism and the passive exercise mechanism, without disturbing the patient's sleep, the foot is continuously exercised moderately to maintain muscle strength and joint flexibility. This ankle nursing device also has a high degree of flexibility and adaptability. It can be disassembled into an independent electric stimulation belt or a foot support according to the specific needs of the patient. For some patients who only need electric stimulation treatment, the device can be disassembled into an independent electric stimulation belt for easy carrying and use; for some patients who need mechanical movement exercise at the same time, the complete foot support can be used for comprehensive treatment. This design can meet the diverse needs of different patients and improve the applicability and practicality of the nursing device.,

[0026] Working principle: First, the foot pad 1 and the instep strap 4 can be put on the user's foot. The top of the foot pad 1 is attached to the sole of the foot, and the instep strap 4 is put on the instep. Then the strap 6 is put on the ankle and connected with a magic tape after being wound. Then the connecting strap 7 is stretched and combined with the male buckle 8 and the female buckle 5. In this way, the foot support is worn. The front end of the winding strap 10 can be stretched and connected to the front block 9. Starting the first micro-motor 12 can wind the winding strap 10, thereby driving the foot to lift, and then let the sole of the foot drop naturally. In this way, the foot muscles can be mildly trained. In addition, the connecting block 14 and the assembly block 13 can be combined for assembly. Then one end of the sliding rod 22 is inserted into the combined sleeve 24. Starting the second micro-motor 16 drives the first cylindrical gear 17, and then the second cylindrical gear 18 drives the rotating column 19 to rotate. Then the force is transmitted through the rotating rod 20, the sliding rod 22 and the combined sleeve 24, so that the foot pad 1 drives the sole of the foot to perform dorsiflexion movement, thus avoiding muscle stiffness.
