Further, through the settings of the solution tank, the push rod, the second piston plate, the connection port, and the guide plate, the downward movement of the second frame body drives the two push rods to move downward. Since the mutually remote ends of the two push rods are respectively in contact with the inclined surfaces on the mutually close sides of the two guide plates, the two push rods move downward and approach each other; so as to adjust the moving distance of the two push rods and the two second piston plates approaching each other according to the distance of the downward movement of the second frame body; the two push rods approaching each other drive the two second piston plates to approach each other, and the two second piston plates approaching each other squeeze the solution in the two solution tanks through the two pairs of connection ports and enter the two pairs of hollow elastic members, so that the resistance generated by the two pairs of hollow elastic members to the back-and-forth movement of the sliding plate continuously increases, making the force required for the patient to raise the leg become larger, so as to achieve the purpose of adjusting the force during the training process; and the resistance size of the patient's active rehabilitation exercise is intelligently regulated through the control system.

[0035] Preferably, referring to the attached Figure 1 , a plurality of massage bumps 17 are fixedly provided on one side of each rotating plate 12 deviating from the housing 11.

[0036] Preferably, referring to the attached Figure 1 , a pedal 13 is fixedly provided on one side of the lower end of each rotating plate 12 deviating from the housing 11.

[0037] In the initial state, the interiors of the hydraulic chamber 21, the hot water chamber 23, and the cold water chamber 24 are all filled with solution.

[0038] Specific usage method of the present invention: The patient sits on the wheelchair 10, places the legs at the rotating plate 12, fixes the patient's legs on the rotating plate 12 through the elastic band 14 and the water sac 15, and places the patient's feet on the pedal 13.

[0039] When the patient performs active rehabilitation exercises, the patient raises the leg to drive the rotating plate 12 to move, and the movement of the rotating plate 12 drives the arc plate 29 and the first piston plate 30 to move. At this time, the first solenoid valve 25 is opened to connect the solution in the hydraulic chamber 21 with the solution in the hot water chamber 23. Then, the heater 27 is started to heat the solution, so that the solution in the hydraulic chamber 21 is heated into hot water. Then, the first piston plate 30 moves to squeeze the hot water in the hydraulic chamber 21, so that the solution in the hydraulic chamber 21 enters several water chambers 18 in the rotating plate 12 through the first connection channel 31 and the second connection channel 32. Then, through the communication between the water chamber 18 and the water bag 15, the hot water enters the water bag 15, and the water bag 15 expands to press the patient's leg, so that a pressing hot therapy can be performed on the patient's leg, which helps to relieve the patient's leg muscle spasm, reduce pain and promote blood circulation.

[0040] At the same time, the second solenoid valve 26 is opened to connect the solution in the hydraulic chamber 21 with the solution in the cold water chamber 24. Then, the cooler 28 is started to cool the solution, so that the solution in the hydraulic chamber 21 is cooled into cold water. Then, the first piston plate 30 moves to squeeze the cold water in the hydraulic chamber 21, so that the solution in the hydraulic chamber 21 enters several water chambers 18 in the rotating plate 12 through the first connection channel 31 and the second connection channel 32. Then, through the communication between the water chamber 18 and the water bag 15, the cold water enters the water bag 15, and the water bag 15 expands to press the patient's leg, so that a cold therapy pressing can be performed on the patient's leg, which can reduce the pain, swelling and inflammation of the patient's leg. And the patient's leg swings back and forth, driving the first piston plate 30 to slide back and forth in the hydraulic chamber 21, so that the solution in the hydraulic chamber 21 is squeezed into the water bag 15, and the solution in the water bag 15 is pumped back into the hydraulic chamber 21, so that the solution moves back and forth between the water bag 15 and the hydraulic chamber 21, which is conducive to the expansion and contraction of the water bag 15 to alternate, and is beneficial to massage the patient's leg, relieve the muscle tension of the patient's leg, reduce pain and promote blood circulation.

[0041] Next, when the patient raises their leg, they encounter resistance from the solution in the hydraulic chamber 21, thus achieving the purpose of assisting in training the patient's leg. The control system manipulates the electric telescopic rod 36 to extend. As the electric telescopic rod 36 extends, it drives the second frame 35 to move downward, causing the skateboard 33 to enter the second frame 35 and positioning the skateboard 33 between two opposite hollow elastic members 34. The patient's leg swings back and forth, driving the rotating plate 12 to move back and forth. The back-and-forth movement of the rotating plate 12 drives the arc plate 29 and the skateboard 33 to move back and forth. Since the skateboard 33 is located between two opposite hollow elastic members 34, the back-and-forth movement of the skateboard 33 compresses the hollow elastic members 34 to generate elastic force. The elastic force generated by the hollow elastic members 34 acts on the skateboard 33, thereby generating resistance to the back-and-forth swing of the skateboard 33 and the arc plate 29. When the patient raises their leg, they are subjected to the elastic force generated by the compression of the hollow elastic members 34, which is beneficial for improving the effect of assisting in training the patient's leg.

[0042] Then, the electric telescopic rod 36 continues to extend, driving the second frame 35 to move downward. The downward movement of the second frame 35 drives the two push rods 39 to move downward. Since the mutually remote ends of the two push rods 39 are respectively in contact with the inclined surfaces on the mutually approaching sides of the two guide plates 40, the two push rods 39 move downward and approach each other. Thus, the downward movement distance of the second frame 35 is used to adjust the moving distance of the two push rods 39 and the two second piston plates 38 approaching each other. The two push rods 39 approaching each other drive the two second piston plates 38 to approach each other. The two second piston plates 38 approaching each other squeeze the solution in the two solution tanks 37 through two pairs of connection ports 41 into the two pairs of hollow elastic members 34, thereby continuously increasing the resistance generated by the two pairs of hollow elastic members 34, making the force required for the patient to raise their leg larger, so as to achieve the purpose of adjusting the force during the training process. And the control system intelligently regulates the resistance magnitude received by the patient during active rehabilitation exercise.

[0043] Finally, ventilation is provided to the patient's leg through a number of ventilation ports 16; furthermore, through a number of massage bumps 17, there is a gap between the patient's leg and the rotating plate 12, which is beneficial for increasing the air circulation speed of the leg during the back-and-forth swing of the patient's leg, thus avoiding the problem that after long-term training, sweat is generated on the leg, affecting the patient's training effect.

[0044] When the patient undergoes passive rehabilitation exercise, the control system manipulates the two stepper motors 43 to start. The start of the stepper motors 43 drives the circular plate 44 to rotate. Through the first bump 45 sliding vertically in the frame 46, the rotation of the circular plate 44 drives the first bump 45 to move, causing the frame 46 to slide horizontally in the housing 11. Then, through the second bump 47 sliding vertically in the frame 46, the horizontal sliding of the housing 11 drives the arc plate 29 to push the rotating plate 12 to swing, so that the rotation of the circular plate 44 can drive the rotating plate 12 to swing back and forth, facilitating the passive rehabilitation exercise of the patient's leg.

[0045] An intelligent regulation type physical therapy device for orthopedic postoperative rehabilitation of the present invention, through the settings of the rotating plate 12, the arc-shaped plate 29, the first piston plate 30, and the hydraulic chamber 21, when the patient raises the leg, it drives the rotating plate 12 to move, and the movement of the rotating plate 12 drives the arc-shaped plate 29 and the first piston plate 30 to move; the movement of the first piston plate 30 squeezes the solution in the hydraulic chamber 21, and when the patient raises the leg, it is resisted by the solution in the hydraulic chamber 21, thereby achieving the purpose of assisting in training the patient's leg; and the patient's leg swings back and forth, driving the first piston plate 30 to slide back and forth in the hydraulic chamber 21, thereby squeezing the solution in the hydraulic chamber 21 into the water bag 15 and pumping the solution in the water bag 15 back into the hydraulic chamber 21, so that the solution moves back and forth between the water bag 15 and the hydraulic chamber 21, facilitating the expansion and contraction of the water bag 15 to alternate, which is beneficial to massaging the patient's leg, relieving muscle tension in the patient's leg, reducing pain and promoting blood circulation. Further through the settings of the second frame 35, the hollow elastic member 34, and the sliding plate 33, when the electric telescopic rod 36 extends, it drives the second frame 35 to move downward, so that the sliding plate 33 enters the second frame 35 and the sliding plate 33 is located between two opposite hollow elastic members 34; the patient's leg swings back and forth, driving the rotating plate 12 to move back and forth, and the back-and-forth movement of the rotating plate 12 drives the arc-shaped plate 29 and the sliding plate 33 to move back and forth; the back-and-forth movement of the sliding plate 33 compresses the hollow elastic member 34 to generate elastic force, and the elastic force generated by the hollow elastic member 34 acts on the sliding plate 33, thereby generating resistance to the back-and-forth swing of the sliding plate 33 and the arc-shaped plate 29, and when the patient raises the leg, it is resisted by the elastic force generated by the compression of the hollow elastic member 34, which is beneficial to improving the effect of assisting in training the patient's leg. Finally, through the settings of the solution tank 37, the push rod 39, the second piston plate 38, the connection port 41, and the guide plate 40, the downward movement of the second frame 35 drives the two push rods 39 to move downward. By the inclined surfaces on the closer sides of the mutually separated ends of the two push rods 39 respectively contacting the closer sides of the two guide plates 40, the two push rods 39 move downward and approach each other; so as to adjust the moving distance of the two push rods 39 and the two second piston plates 38 approaching each other according to the downward movement distance of the second frame 35; the two push rods 39 approaching each other drive the two second piston plates 38 to approach each other, and the two second piston plates 38 approaching each other squeeze the solution in the two solution tanks 37 through the two pairs of connection ports 41 into the two pairs of hollow elastic members 34, so that the resistance generated by the two pairs of hollow elastic members 34 to the back-and-forth movement of the sliding plate 33 continuously increases, making the force required for the patient to raise the leg become larger, so as to achieve the purpose of adjusting the force during the training process.

[0046] An intelligent regulation type physical therapy device for orthopedic postoperative rehabilitation according to the present invention, through the settings of the hot water chamber 23, the heater 27, and the first electromagnetic valve 25, the solution in the hydraulic chamber 21 is interconnected with the solution in the hot water chamber 23. The heater 27 is activated to heat the solution, so that the solution in the hydraulic chamber 21 is heated into hot water. Then, the first piston plate 30 moves to squeeze the hot water in the hydraulic chamber 21, so that the solution in the hydraulic chamber 21 enters a plurality of water chambers 18 and water sacs 15 in the rotating plate 12 through the first connection channel 31 and the second connection channel 32.
