An adjustment component 20 is provided on the inner wall of the shoe sole 1. A breathable component 23 is provided at the output end of the dual-head motor 3. A movable frame 14... Motors 15 are installed on both inner walls. The output end of motor 15 is fixedly connected to a rotating wheel 16. Two massage frames 17 are slidably connected to the top of the moving frame 14. Multiple soft rubber covers 18 are installed on one end of the massage frame 17. Multiple springs 19 are provided on the inner wall of the massage frame 17. The rotating wheel 16 is rotatably connected to the inner wall of the massage frame 17. Multiple limiting blocks are fixedly connected to the inner wall of the moving frame 14. Springs 19 are provided on the outer wall of the limiting blocks. Bevel gear 7 is slidably connected to the inner wall of the multiple limiting blocks. Bevel gear 6 is meshed with the tooth end of bevel gear 7. Worm 8 is meshed with the tooth end of worm wheel 10. Rotating wheel 9 is slidably connected to the bottom end of massage frame 11. Multiple springs 12 are provided on the inner wall of the connecting frame 2.

[0026] Specifically, the spring 12 is positioned between the connecting frame 2 and the massage frame 11, ensuring that the bottom of the massage frame 11 is always in contact with the outer wall of the rotating wheel 9. The four springs 19 move the massage frame 17 outward, ensuring that the inner wall of the massage frame 17 is always in contact with the outer wall of the rotating wheel 16. The dual-head motor 3, through the transmission structure of bevel gear 6, bevel gear 7, and rotating rod 5, moves the soft rubber cover 13 up and down via the rotating wheel 9 and the massage frame 11, bringing it into contact with the sole of the foot. The motor 15, through the rotating wheel 16 and the massage frame 17, moves multiple soft rubber covers 18, which massage the ankle, thus relieving foot soreness.

[0027] Please see the appendix Figure 2 , see attached Figure 4 Appendix Figure 6 and attached Figure 8 The adjustment assembly 20 includes a threaded rod 2001, two threaded rods 2001 are rotatably connected to the inner wall of the sole 1, both ends of the threaded rod 2001 are fixedly connected to a synchronous pulley 2002, the teeth of the synchronous pulley 2002 are meshed with a synchronous belt 2003, both sides of the outer wall of the threaded rod 2001 are threadedly connected to a movable frame 2004, both ends of one of the threaded rods 2001 are fixedly connected to a rotating block 2005, the inner wall of the sole 1 is rotatably connected to a threaded rod 2006, the outer wall of the threaded rod 2006 is threadedly connected to a movable frame 14, one end of the threaded rod 2006 is fixedly connected to a rotating block 2007, the movable frame 14 is slidably connected to the inner wall of the sole 1, the movable frame 2004 is slidably connected to the outer wall of the sole 1, and the movable frame 14 and the movable frame 2004 are slidably connected to the outer wall of the soft plastic pad 22.

[0028] Specifically, by rotating the rotating block 2005, it drives the threaded rod 2001 connected to it, and through the synchronous pulley 2002 and the synchronous belt 2003, it drives another threaded rod 2001 to rotate, so that the two threaded rods 2001 together drive the two movable frames 2004 to move inward. Rotating the rotating block 2007, it drives the movable frame 14 to move through the threaded rod 2006, so that the movable frame 14 and the two movable frames 2004 can change the size of the sole 1 to adapt to different feet.

[0029] Please see the appendix Figure 3 Appendix Figure 4 and attached Figure 8 The breathable component 23 includes fan blades 2301. Both fan blades 2301 are fixedly connected to the output ends on both sides of the dual-head motor 3. Ventilation holes 2302 are provided on both sides of the sole 1. Multiple ventilation grooves 2303 are provided on the top of the sole 1 and the connecting frame 2. The ventilation holes 2302 are connected to the inner wall of the connecting frame 2. The ventilation grooves 2303 are in contact with the bottom of the soft plastic pad 22.

[0030] Specifically, the dual-head motor 3 drives the two fan blades 2301 to rotate, causing the fan blades 2301 to draw in air from outside the sole 1 through the ventilation holes 2302. The air is then blown from the ventilation holes of the sole 1 to the sole through the ventilation grooves 2303 on the connecting frame 2 and the sole 1, thereby reducing the stuffiness of the sole.

[0031] Please see the appendix Figure 1 and attached Figure 2The top of the movable frame 14 is rotatably connected to the fixed frame 21. The top of the sole 1 and the connecting frame 2 are equipped with soft plastic pads 22. The fixed frame 21, the soft plastic pads 22 and the movable frame 2004 are respectively provided with fixed holes 1, 2 and 3. Fixed straps 1, 2 and 3 are respectively installed on the outer walls of fixed holes 1, 2 and 3. All three fixed straps are equipped with Velcro and Velcro, and the Velcro is installed on the outer wall of the Velcro.

[0032] Specifically, the fastener on the first fixing strap contacts the fastener to fix the fixing frame 21 to the foot, while the second and third fixing straps fix the soft plastic pad 22 and the movable frame 2004 to the sole of the foot, thus making it convenient for the patient to wear.

[0033] Working principle: Place the patient's foot on the soft plastic pad 22, with the sole of the foot resting on the soft plastic cover 13. Then rotate rotating block 1 2005 and rotating block 2007 respectively. Rotating block 1 2005 drives two moving frames 2004 towards the sole of the foot via threaded rod 2001, synchronous pulley 2002 and synchronous belt 2003. This causes the soft plastic pad 22 to come into contact with the sole of the foot on both sides. Then, fixing belt 2 and fixing belt 3 are used to fix the sole of the foot. Rotating block 2 2007 drives moving frame 14 and fixing frame 21 via threaded rod 2006. Moving frame 14 comes into contact with the heel, and fixing frame 21 fixes the lower leg through fixing one, achieving the effect of adapting to different foot sizes.

[0034] After wearing the orthopedic device, patients can quickly connect to the Bluetooth smart module inside the device by clicking "Bluetooth pairing" on their mobile app and smartwatch. After their children bind the patient's account to the mobile app, they can remotely view the patient's rehabilitation data and recovery curve, and keep track of the rehabilitation progress without having to be present in person.

[0035] During the correction process, the built-in angle and pressure sensors collect data on the correction angle and foot force distribution in real time, which are then transmitted to the mobile APP via Bluetooth smart module. The APP automatically generates a recovery curve and displays it in large text.

[0036] When the patient feels soreness and swelling, they can click the "Massage" button on the APP to activate the dual-head motors 3 and 15. The dual-head motors 3 and 15 indirectly drive the soft rubber covers 13 and 18 to move through the massage frame 11 and massage frame 2 17. The massage frame 11, located below the acupoints on the sole of the foot, has soft rubber covers 13 installed at its top. This allows the soft rubber covers 13 to accurately correspond to and cover the key acupoints on the sole of the foot, enabling multiple soft rubber covers 13 and 18 to massage the patient's sole and ankle respectively. The heating component heats up to 38-42℃, while the low-frequency vibration unit drives the gentle pressure massage points to vibrate at a low frequency of 20-50Hz, achieving a combination of heating and vibration massage to relieve soreness and swelling in the feet.

[0037] When the connecting frame 2 moves the soft rubber cover 13, it also drives the two fan blades 2301 to rotate, allowing outside air to ventilate the bottom of the soft plastic pad 22 through the fan blades 2301, the vent 2302 and the vent groove 2303, thereby reducing the stuffiness of the soles of the feet.

[0038] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
