[0025] The scoliosis correction mechanism of the present invention is described in more detail below with reference to the accompanying drawings and through specific implementation methods.

[0026] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0027] See also Figure 1-Figure 6 The scoliosis correction mechanism of this embodiment can adjust the front-back curvature of the patient's spine in a sitting position and keep the spine at a certain curvature, thereby correcting the front-back curvature of the spine. The patient can swing left and right on the seat in a circular motion, and the amplitude of the swing can be changed at will, so as to exercise the patient's waist muscles and maintain the normal curvature of the spine. In this embodiment, it mainly includes a swingable support plate 1 on the seat. The support plate 1 is provided with a seat cushion 2 that can slide forward and backward. A servo motor 7 is fixedly provided at the middle of the rear end of the support plate 1. The output end of the servo motor 7 is fixedly provided with a first screw 8 that is rotatably arranged with the support plate 1, and the first screw 8 is threadedly connected with the middle of the seat cushion 2. The seat cushion 2 is slidably arranged with the support plate 1 through guide rails 9 fixedly provided on both sides of the top of the support plate 1. A fixing belt 6 is fixedly provided on the support plate 1 and the back plate. The fixing belt 6 is composed of a strap 10 with Velcro provided on the left and right sides of the seat, and a blocking cloth 11 that covers the internal structure is fixedly provided on the side of the support plate 1. This prevents the patient from directly seeing the internal structure, which may cause fear of spinal curvature correction, leading to tension and muscle tightness during correction, which may affect the correction effect. A control module is also provided, which is a mature single-chip microcomputer technology and will not be described in detail here. The servo motor 7 is centrally controlled by the control module.

[0028] A curvature adjustment unit 4 is provided inside the lower side of the back panel of the seat. A soothing pad 5 abutting against the curvature adjustment unit 4 is provided on the front side of the back panel. The curvature adjustment unit 4 includes a plurality of extrusion plates 401 arranged in groups inside the back panel, which abut against each other up and down and are arranged to imitate the curvature of the spine, and the front side of the extrusion plate 401 abuts against the soothing pad 5. An electric push rod 402 is fixedly provided horizontally in the middle of the rear side of the extrusion plate 401, and the electric push rod 402 is centrally controlled by a control module. The fixed end of the electric push rod 402 is fixedly provided to the inner wall of the back panel. Guide telescopic rods 403 are fixedly provided horizontally at both ends of the rear side of the extrusion plate 401, and the sleeve end of the guide telescopic rod 403 is fixedly provided to the inner wall of the back panel.

[0029] After the patient sits on the cushion 2, the patient is fixed by the strap 10 with Velcro for subsequent correction and treatment. When the patient is corrected, the servo motor 7 is controlled by the control module to work, and the first screw 8 is driven to rotate on the support plate 1. At this time, the first screw 8 drives the cushion 2 to move forward and backward along the guide rail 9, thereby realizing the movement of the patient's body. Then the corresponding electric push rod 402 is controlled by the control module to work, and at this time, the electric push rod 402 pushes the extrusion plate 401 to squeeze the patient's back through the soothing pad 5, and keeps the patient's spine at a suitable curvature for a certain time, thereby realizing the correction of the spine. At the same time, the spinal curvature of the patient can be cyclically squeezed by controlling the corresponding electric push rod 402 to work, thereby realizing the activity of the patient's spine and the exercise of the muscles in the middle part of the spine. In this process, the guide telescopic rod 403 guides the extrusion plate 401 to avoid the situation of dislocation. At this time, the curvature of the patient's spine is corrected by the forward and backward movement of the cushion 2 and the relative forward and backward movement of the extrusion plate 401.

[0030] To exercise the patient's waist muscles. Figure 3-Figure 6 In this embodiment, an amplitude adjustment unit 3 for changing the swing amplitude of the pallet 1 is provided at the bottom end of the pallet 1. The amplitude adjustment unit 3 includes a disc 301 fixedly arranged in the middle of the bottom end of the pallet 1. A slide rail groove 302 is provided on the side of the disc 301, and a swing block 303 is rotatably arranged at the bottom end of the pallet 1 on the side of the slide rail groove 302. A first motor 304 is fixedly arranged at one end of the swing block 303, and the first motor 304 is centrally controlled by a control module. A first gear 305 is fixedly arranged at the output end of the first motor 304. A second screw 306 is sleeved inside the swing block 303. A second gear 307 meshing with the first gear 305 is rotatably arranged at the end of the swing block 303, and the middle part of the second gear 307 is threadedly arranged with the second screw 306. A T-shaped rod 308 rotatably connected to the second screw rod 306 is disposed in the slide rail groove 302 , and upper and lower ends of the T-shaped rod 308 are slidably disposed with the slide rail groove 302 via sleeve bearings 309 .

[0031] When the swing amplitude needs to be adjusted, the control module controls the first motor 304 to work and drives the first gear 305 to rotate. The second screw 306 is rotated by the second gear 307 meshing with the first gear 305, and the second screw 306 drives the T-shaped rod to move in the slide rail groove 302, thereby changing the position of the T-shaped rod 308, thereby changing the amplitude of the rotation of the support plate 1. In this process, the bearing 309 reduces the resistance during the movement, and the service life of the T-shaped rod 308 is extended.

[0032] A second motor 310 with a reducer is fixedly provided at the bottom end of the support plate 1, and the second motor 310 is centrally controlled by a control module. A third gear 311 is fixedly provided at the output end of the reducer. A rotating wheel 312 is rotatably provided at the bottom end of the support plate 1, and a fourth gear 313 meshing with the third gear 311 is fixedly provided on the upper part of the rotating wheel 312. A connecting rod 314 is eccentrically rotatably provided at the bottom end of the rotating wheel 312, and the other end of the connecting rod 314 is rotatably provided with one side of the bottom end of the swing block 303.

[0033] When the patient's waist needs to be swung left and right in a circular motion, the control module controls the second motor 310 to work, and the power output by the second motor 310 is decelerated and torque-increased by the reducer to rotate the third gear 311. The third gear 311 and the fourth gear 313 drive the rotating wheel 312 to rotate, and the rotating wheel 312 drives the connecting rod 314 to drive the swing block 303 to swing, and then the disc 301 is rotated through the hinge point between the swing block 303 and the support plate 1, so as to rotate the support plate 1. The patient can swing left and right in a circular motion on the chair, so as to exercise the patient's waist muscles, support the patient's spine, maintain the normal curvature of the spine, and accelerate blood circulation and relax muscles.

[0034] The method of using the scoliosis correction mechanism of the utility model is as follows: first, when the spinal curvature needs to be corrected, the patient sits on the cushion 2 and fixes the legs and body with the fixing belt 6. Then the servo motor 7 is controlled by the control module to work, and the first screw 8 is driven to move the cushion 2 forward and backward along the guide rail 9. Thereby changing the front and rear position of the patient. At the same time, the electric push rod 402 is controlled by the control module to work, so that the extrusion plate 401 moves forward and backward along the guide telescopic rod 403, so that the patient's spine is squeezed to a suitable curvature and lasts for a certain period of time. After a period of time, the corresponding extrusion plate 401 can be moved forward and backward by controlling the corresponding electric push rod 402, so that the patient's spine is divided into multiple parts from top to bottom and moves forward and backward respectively. Then the spine is moved and relieved, and the muscles on the side of the spine can be exercised. When the waist needs to be exercised, the second motor 310 is controlled by the control module to work, so that the rotating wheel 312 is rotated by the third gear 311 and the fourth gear 313. The rotating wheel 312 drives the connecting rod 314 to move so that the swing block 303 swings in a cycle. At this time, the swing block 303 rotates the support plate 1 through the second screw rod 306. As a result, the patient's waist swings left and right in a cycle. In order to exercise the patient's waist muscles, support the patient's spine, maintain the normal curvature of the spine, and accelerate blood circulation and relax muscles. In this process, the T-bar 308 moves in the slide rail groove 302 through the bearing 309. When the amplitude of the swing needs to be adjusted, the first motor 304 is controlled to work through the control module, so that the second screw rod 306 is rotated through the first gear 305, and then the position of the T-bar 308 in the slide rail groove 302 is changed. At this time, the swing amplitude of the patient's waist changes.
