A rotating motor 203 is fixedly installed on the right side of the training chair 1. The output end of the rotating motor 203 power passes through the training chair 1 and is fixedly connected to the right end of the rotating shaft 201. Two electric push rods 215 are fixedly installed on the inner top wall of each moving plate 202. A support plate 216 is fixedly installed on the telescopic end of each group of electric push rods 215. The power provided by the electric push rods 215 is used to drive the support plate 216 to move up and down, so that the device can adjust the height of the support plate 216 according to the height of the patient, thereby facilitating the placement of the feet of patients of different heights.

Please refer to Figures 1-3. A rotating frame 204 is fixedly installed on the left end of the rotating shaft 201. The rotating frame 204 is composed of a circular disk and a rectangular block, so that the circular disk drives the rectangular block to rotate. Two elastic bands 217 are fixedly installed on the front of each movable plate 202. A first Velcro 218 is fixedly installed on the inner wall of each elastic band 217. Two second Velcro 219 are fixedly installed on the right side of each movable plate 202. The elastic band 217 is passed around the patient's legs, and the first Velcro 218 is adhered to the second Velcro 219, thereby fixing the patient's legs and avoiding the patient's leg movement as much as possible.

Please refer to Figures 1, 2 and 3. A connecting bearing 205 is fixedly installed on the left side of the training chair 1, a connecting gear 206 is fixedly installed on the left side of the outer ring of the connecting bearing 205, a connecting plate 207 is fixedly installed on the left side of the connecting gear 206, a pressure sensor 208 is fixed on the back of the connecting plate 207, the center of the connecting gear 206 is hollow, so that the connecting gear 206 does not contact the rotating shaft 201, the model of the pressure sensor 208 is MS54XX, a pointer 220 is fixedly installed on the bottom surface of the connecting plate 207, and a dial 221 is fixedly installed on the left side of the training chair 1. The installation of the pointer 220 and the dial 221 makes it convenient for the user to observe the indication of the knee joint bending angle, thereby facilitating the user to adjust.

Please refer to Figures 1 and 2. A rotating motor 209 is fixedly installed on the left side of the training chair 1. A rotating gear 210 is fixedly installed on the output end of the power of the rotating motor 209. The outer surface of the rotating gear 210 is meshed with the outer surface of the connecting gear 206. A fixed bearing 222 is fixedly installed on the right side of the rotating gear 210. The right side of the inner ring of the fixed bearing 222 is fixedly connected to the left side of the training chair 1. The installation of the fixed bearing 222 stabilizes the rotating gear 210, thereby minimizing the shaking of the rotating gear 210 during rotation, thereby ensuring the stability of the rotation of the rotating gear 210.

Please refer to Figures 1-4. A controller 211 is fixedly installed on the inner wall of the training chair 1. The controller 211 is electrically connected to the rotating motor 203, the pressure sensor 208, the rotating motor 209, the cylinder 214 and the electric push rod 215 through wires. A battery 223 is fixedly installed on the inner top wall of the training chair 1. The battery 223 is electrically connected to the rotating motor 203, the pressure sensor 208, the rotating motor 209, the controller 211, the cylinder 214 and the electric push rod 215 through wires. The installation of the battery 223 can provide electrical energy to the electrical equipment of the device, so that the device does not need to be limited by the length of the wires, thereby increasing the practicality of the device.

Working principle: When in use, the user first turns on the cylinder 214 and the electric push rod 215, and uses the power provided by the cylinder 214 to drive the training chair 1 to move up and down, and uses the power provided by the electric push rod 215 to drive the support plate 216 to move up and down, so that the user can adjust the height of the training chair 1 and the support plate 216 according to the patient's height. Then the patient sits on the training chair 1, and leans his legs on the moving plate 202, and places his feet on the support plate 216. Then the user wraps the elastic band 217 around the patient's legs and sticks the first Velcro 218 on the second Velcro 219, thereby fixing the patient's legs. Then the user turns on the rotating motor 209 according to the patient's training intensity, and uses the power provided by the rotating motor 209 to drive the rotating gear 210 to rotate, so that the rotating gear 210 drives the connecting gear 206 meshing with it to rotate. The connecting gear 206 drives the connecting plate 207 and the pointer 220 to rotate, so that the pointer 220 points to the corresponding scale on the dial 221. Then the user turns on the rotating motor 203 and uses the power provided by the rotating motor 203 to drive the rotating shaft 201 to rotate, so that the rotating shaft 201 drives the movable plate 202 to rotate, thereby achieving the purpose of performing knee joint rehabilitation training for the patient. At the same time, the rotating shaft 201 drives the rotating frame 204 to rotate, so that when the rotating frame 204 is rotating, when the rotating frame 204 contacts the pressure sensor 208, the pressure sensor 208 transmits a signal to the controller 211, so that the controller 211 controls the rotating motor 203 to run in reverse until the movable plate 202 returns to its original position, thereby completing the first cycle of rehabilitation training, and then repeating the training process of the first cycle, thereby achieving the purpose of performing knee joint rehabilitation training for the patient.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
