The strap 303 is an important element to achieve a tight connection between the front shell 2 and the rear shell 1. The inner wall of the connecting groove 302 is smooth to reduce the friction of the strap 303 when passing through, while having a certain friction to ensure that the strap 303 does not slide easily after passing through and tightening, thereby ensuring the stability of the connection between the front and rear shells. The patient can easily tighten or loosen the strap 303 through the Velcro 304, thereby adjusting the degree of fixation of the front and rear shells to the ankle to adapt to the ankle thickness of different patients and the needs of different rehabilitation stages. The ventilation groove 4 allows the patient's skin to breathe normally when using the device to avoid problems such as excessive sweating, stuffiness and discomfort of the skin due to long-term closure.

[0037] Please see attached Figure 3 -Attached Figure 5 A massage mechanism 5 and a pressing mechanism 9 are provided at the middle and lower part of the rear end of the rear shell 1. The massage mechanism 5 includes an assembly cabin 501. The front side of the assembly cabin 501 is fixedly connected to the middle and lower part of the rear end of the rear shell 1.

The permanent magnet 903 has stable magnetism and cooperates with the electromagnetic coil 904 provided inside the installation cabin 901. The electromagnetic coil 904 is cleverly arranged inside the installation cabin 901 and surrounds the permanent magnet 903. When the electromagnetic coil 904 is energized, a magnetic field is generated. This magnetic field interacts with the magnetic field of the permanent magnet 903, causing the contact 902 to rotate. Through the wire 7, external electrical energy can be transmitted to the electromagnetic coil 904 inside the installation cabin 901, providing the electromagnetic coil 904 with energy to generate a magnetic field.

A pressure sensor 605 is arranged inside the mounting plate 602. The pressure sensor 605 transmits the collected data to the central control system. The mounting plate 602 provides a reliable foundation for the subsequent installation of other components such as the air bag 603. The air bag 603 can be inflated after it is inflated. It can make adaptive adjustments according to the shape and pressure changes of the ankle, provide uniform and gentle support and wrapping for the ankle, thereby effectively reducing the pressure on the ankle and preventing damage caused by excessive local pressure. The air delivery pipe 604 is used as a channel for gas transmission, and the exhaust valve 606 is set to discharge the excess gas in the airbag 603 when necessary. The small air pump 601 is the power source of the entire inflation mechanism 6. Although it is small in size, it has enough power to inflate the airbag 603. When the patient uses the rehabilitation device, whether in a static state or in an activity, the pressure sensor 605 can accurately collect the pressure data in the airbag 603. Then, these collected data will be transmitted to the central control system in a high-speed and stable manner through a dedicated communication line. The central control system can accurately control the small air pump 601 and the exhaust valve 606 according to the received pressure data, so as to realize the dynamic adjustment of the pressure in the airbag 603 to meet the support and pressure requirements of the patient's ankle in different rehabilitation stages and different activity states.

[0041] Please refer to the attached Figure 7 The inflation mechanism 6 is provided with an angle adjustment mechanism 8, which includes a rotating connecting shaft 801, the middle part of which is fixedly connected to the bottom front side of the rear mounting plate 602 in the inflation mechanism 6, the left and right ends of the rotating connecting shaft 801 are rotatably connected with steering blocks 811, the bottom end of the steering block 811 is fixedly connected with an adjustment plate 802, the top rear side of the adjustment plate 802 is symmetrically distributed and fixedly connected with a slide block 803, the interior of the slide block 803 is slidably connected with a slide rod 804, and the outer end of the slide rod 804 is rotatably connected with a connecting rod 80 5, and the other end of the connecting rod 805 is rotatably connected to a connecting block 806, the top of the connecting block 806 is fixedly connected to the bottom end of the rear mounting plate 602 in the inflation mechanism 6, and the adjacent ends of the two sets of sliding rods 804 are provided with a transmission assembly, and the rear mounting plate 602 can rotate around the rotating connecting shaft 801 at a certain angle. When the sliding rod 804 is subjected to an external force, it can move along the direction of the sliding groove of the sliding groove block 803. During the movement, the sliding rod 804 can transmit the force through the connecting rod 805 and can adapt to the change of force at different angles;

[0042] The transmission assembly includes a threaded block 808, the left and right ends of which are fixedly connected to the adjacent ends of the two sets of sliding rods 804 respectively, the middle part of the threaded block 808 is threadedly connected to a screw 807, the rear end of the screw 807 is fixedly connected to one end of a second rotating shaft 809, the other end of the second rotating shaft 809 penetrates the rear shell 1 and is fixedly connected to a knob 810, the movement of the threaded block 808 can be directly transmitted to the sliding rod 804, when the screw 807 rotates, due to the action of the thread, the threaded block 808 will move linearly along the axial direction of the screw 807, and the second rotating shaft 809, the screw 807 and a series of components such as the rotating knob 810 are driven to move.

[0043] Please refer to the attached Figure 2 and attached Figure 6 , a temperature regulating mechanism 10 is arranged inside the rear shell 1, and the temperature regulating mechanism 10 includes a temperature control belt 1001, and the outer wall of the temperature control belt 1001 is fixedly connected to the middle and lower part of the inner wall of the rear shell 1, and the temperature control belt 1001 is provided with a heat preservation layer 1004 and a diaphragm 1003 from the outside to the inside, and a heating wire 1006 and a semiconductor cooling sheet 1005 are arranged equidistantly between the diaphragm 1003 and the heat preservation layer 1004, and a temperature control module 1002 is arranged inside the temperature control belt 1001, and the temperature control module 1002 transmits the received signal to the central control system. The main function of the heat preservation layer 1004 is to reduce the heat loss. It adopts efficient heat preservation materials, such as high-quality polyurethane foam or vacuum insulation board, and the diaphragm 1003 plays the role of isolation and protection. It separates the heating wire 1006 and the semiconductor cooling sheet 1005 from the patient's skin, and at the same time keeps The material of the diaphragm 1003 has good thermal conductivity and biocompatibility, such as medical silica gel, etc. The semiconductor cooling sheet 1005 is the core component to realize the ice compress function. Based on the Peltier effect, when the current passes through, according to Joule's law, the heating wire will generate heat to provide a warm environment for the ankle, promote blood circulation and tissue repair. When the current passes through, it can absorb heat on one side and release heat on the other side. Through reasonable design, it can absorb heat on the side in contact with the ankle, thereby reducing the local temperature of the ankle and reducing inflammation and swelling. The temperature control module 1002 is the intelligent control core of the entire temperature control mechanism 10. The temperature control module 1002 can also receive various signals from the outside, such as the temperature command set by the user through the control panel, the command of the central control system to automatically adjust the temperature according to the patient's recovery stage, etc. Then, the temperature control module 1002 will accurately transmit the received signals to the central control system, and the central control system will further control the working state of the heating wire 1006 and the semiconductor cooling sheet 1005 according to this information, so as to achieve accurate regulation of the ankle temperature.

[0044] Please refer to the attached Fig.10, the central control system includes:

[0045] Acquisition module: used to transmit the data collected by the pressure sensor 605 and the signal received by the temperature control module 1002 to the central control system;

[0046] Analysis module: It analyzes the data and signals collected in the central control system through the data processing unit;

[0047] Driving module: It drives the small air pump 601, the exhaust valve 606, the semiconductor cooling sheet 1005 and the heating wire 1006 through the analyzed information.

[0048] Working principle: After the patient puts the injured foot between the rear shell 1 and the front shell 2, the position of the front shell 2 is adjusted so that the rear shell 1 and the front shell 2 fit the foot, and then the strap 303 is passed through the rear shell 1 and the connecting groove 302 on the connecting plate 301, and the strap 303 is tightened so that the front shell 2 and the rear shell 1 fix the foot, and the Velcro 304 prevents the strap 303 from loosening, and then the temperature control belt 1001 is started through the temperature control module 1002, the semiconductor refrigeration sheet 1005 is powered on, the temperature is reduced, and the cold air passes through the diaphragm 1003 to apply ice to the ankle. The ice compress function can reduce the local blood circulation speed by contracting the blood vessels, reducing blood and tissue The accumulation of tissue fluid in the injured area effectively controls inflammation and swelling. When entering the subacute and chronic stages, the patient needs to start moving to restore foot performance. Before exercising, turn the knob 810. Under the connection of the second rotating shaft 809, the screw 807 rotates with the knob 810. During the rotation of the screw 807, the threaded block 808 moves. During the forward movement of the sliding rod 804 driven by the threaded block 808, the sliding rod 804 moves along the sliding groove block 803. Due to the connection of the connecting rod 805 and the rotation of the steering block 811 and the rotating connecting shaft 801, the rear mounting plate 602 presents a certain tilt angle, so that the ankle is supported. The small air pump 601 is then started, and the gas is transported to the airbag 603 through the air pipe 604. After the airbag 603 is inflated, it fits the contour of the foot to protect the ankle. During walking, the pressure sensor 605 is subjected to the pressure of the footsteps during walking, and the gas in the airbag 603 is regulated in real time. The excess gas is discharged from the exhaust valve 606. After walking, the temperature control belt 1001 is started through the temperature control module 1002, and the heating wire is energized. The heat generated passes through the diaphragm 1003 to apply heat to the ankle, and the massage motor 506 and the wire 7 are started to supply the electromagnetic coil 904. After the electromagnetic coil 904 is energized, the permanent magnet 903 rotates, and the contact 9 02 rotates accordingly, and the massage motor 506 rotates the driving gear 505. Under the meshing connection between the driving gear 505 and the driven gear 504, the first rotating shaft 507 rotates, and the roller 502 and the massage head 503 on the first rotating shaft 507 rotate at the same frequency. The rotating contacts 902, rollers 502 and massage heads 503 massage the ankle. Hot compress and massage can dilate blood vessels, increase blood flow to the injured area, and provide more nutrients (such as oxygen, glucose, amino acids, etc.) for tissue repair. At the same time, hot compress can also relieve muscle tension and promote the recovery of joint flexibility, which is very critical for the functional recovery stage in the ankle rehabilitation process.
