[0032] like Figure 1-6 As shown, an embodiment of the present invention provides an intelligent wearable joint stability monitoring and feedback device, which is composed of a monitoring mechanism 10, a wearing mechanism 20 and a feedback mechanism 30.

[0033] The monitoring mechanism 10 includes a first movable part 11 and a second movable part 12. The monitoring mechanism 10 is used to monitor the bending state of the knee joint in real time. A mounting groove 17 is provided on one side of the second movable part 12. The internal rotation of the mounting groove 17 is connected to a rotating shaft 18. One end of the rotating shaft 18 is fixedly connected to the first movable part 11. A rotor fixing plate 43 is fixedly connected to one side of the first movable part 11.

A stator electrode 41 is installed on one side of the stator fixing plate 19. The stator electrode 41 contacts the rotor electrode 42 to generate friction when the knee joint moves to monitor the activity state of the knee joint. A slide groove 13 is symmetrically provided on one side of the first movable part 11.

[0034] In one embodiment, a hollow groove 15 is symmetrically opened on one side of the second movable part 12 to reduce the weight of the second movable part 12. A positioner 16 is installed on one side of the first movable part 11 and the second movable part 12. The positioner 16 records the motion trajectory of the first movable part 11 and the second movable part 12, and cooperates with the stator electrode 41 and the rotor electrode 42 to monitor the knee joint movement, thereby improving the monitoring accuracy.

[0035] The wearing mechanism 20 includes a first arc-shaped member 21 and a second arc-shaped member 22. The wearing mechanism 20 is used to wear the monitoring mechanism 10 on both sides of the knee joint. The first arc-shaped member 21 is fixedly connected to one side of the second movable member 12. A sleeve portion 29 is integrally formed on one side of the second arc-shaped member 22. The sleeve portion 29 is slidably connected to the first movable member 11 through a slide groove 13. A strap 24 is fixedly connected to one side of the first arc-shaped member 21 and the second arc-shaped member 22. A groove 25 is provided on one side of the first arc-shaped member 21 and the second arc-shaped member 22. A guide rail 26 is symmetrically installed inside the groove 25. The guide rail 26 is If the electric type is used, a separate control button can be added to the guide rail 26, or the guide rail 26 can be controlled by remote control. The movable end of the guide rail 26 is fixedly connected to the slider 27, and one end of the strap 24 is fixedly connected to the slider 27, so that the guide rail 26 cooperates with the slider 27 to drive the strap 24 to move, so that the strap 24 is contracted and the wearing is completed quickly. A pressure sensor 36 is installed on one side of the strap 24, and an anti-slip pad 37 is fixedly connected to one side of the pressure sensor 36. After the pressure sensor 36 is subjected to a certain degree of pressure, the guide rail 26 is stopped to complete the wearing, thereby preventing excessive contraction from causing marks on the limbs.

[0036] In one embodiment, in order to reduce discomfort to the wearer when wearing the device, a cushion 23 is fixedly connected to one side of the first arc-shaped member 21 and the second arc-shaped member 22, and through holes 28 are evenly distributed on one side of the cushion 23.

[0037] In one embodiment, in order to facilitate the adjustment of the position of the second arc-shaped member 22, screw holes 14 are equidistantly distributed on one side of the first movable member 11, and a fixing bolt 201 is threadedly connected to one side of the sleeve portion 29. One end of the fixing bolt 201 is threadedly connected to the first movable member 11 through the screw hole 14, so that the wearing position of the second arc-shaped member 22 can be adjusted at any time according to needs during the wearing process.

[0038] The feedback mechanism 30 includes a vibrator 31 and a mounting box 32. The feedback mechanism 30 is used to provide abnormal feedback to the wearer. The vibrator 31 is symmetrically fixedly connected to one side of the strap 24, and the mounting box 32 is fixedly connected to one side of the first movable part 11. A wireless connector 33 and a processor 34 are respectively installed on one side of the interior of the mounting box 32, and a power supply 35 is installed on one side of the interior of the mounting box 32.

[0039] When the present invention is working, the first arc-shaped member 21 and the second arc-shaped member 22 are mounted on the limbs, so that the connection between the first movable member 11 and the second movable member 12 is located at the knee joint, the limbs are located between the first arc-shaped member 21 and the second arc-shaped member 22 and the strap 24, the guide rail 26 at the first arc-shaped member 21 is started, the slider 27 is driven to move, so that the strap 24 at the first arc-shaped member 21 is tightened, the second movable member 12 is first worn on the limbs, and then the limbs are bent, the position of the second arc-shaped member 22 is adjusted according to the needs, and then the position of the second arc-shaped member 22 is fixed by the fixing bolt 201, the guide rail 26 at the second arc-shaped member 22 is started, the strap 24 is tightened to complete the wearing of the second arc-shaped member 22, and the first movable member 1 1 is fixed to the limb. During wearing, the pressure sensor 36 is pressed by the limb and the strap 24. When a certain degree of pressure is applied, the guide rail 26 stops to prevent the strap 24 from being over-contracted. After wearing, the first movable member 11 and the second movable member 12 are located on the side of the knee joint, and the vibrator 31 on the strap 24 is located on the front and back sides of the limb. When the knee joint moves, the limb drives the first movable member 11 and the second movable member 12 to move, and the rotor electrode 42 and the stator electrode 41 at the connection between the first movable member 11 and the second movable member 12 generate friction, so as to obtain the activity state of the knee joint. When the processor 34 detects that the knee joint posture is abnormal, the corresponding vibrator 31 is started to vibrate the limb for feedback, so that the wearer can adjust the knee joint posture.

Any person skilled in the art can easily think of various changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
