[0032] When in use, the patient's legs are spread open, and then the support board 3 is placed on the bed so that the support board 3 is located between the patient's legs. The telescopic rod of the electric push rod Ⅰ2 is controlled to extend to move the machine 1 upward, thereby driving the rotating shaft 4, the gear ring 7, the connecting rod 8, the connecting frame 9, the sliding plate 10, the splint Ⅰ11 and the splint Ⅱ12 to move upward. Then, the electric push rod Ⅱ19 is used to drive the slide plate 20 to move away from each other until the slide plates 20 on the left and right sides contact the patient's legs respectively. Then, the air pump 22 is used to pump air into the airbag Ⅰ21 through the trachea Ⅰ23 to expand the airbag Ⅰ21, so that the airbag Ⅰ21 lifts the patient's legs through expansion, and then the electric push rod Ⅱ19 is used to drive the slide plate 20 to move toward the side close to each other. The two slides 20 on the left and right sides respectively drag the patient's legs closer until the patient's legs are aligned with the two infrared sensors 24. When the infrared sensor 24 senses the soles of the patient's feet (when the infrared sensor senses temperature changes, especially when the human body enters its sensing range, the pyroelectric element inside the infrared sensor will lose charge balance due to temperature changes, thereby generating an electrical signal), the infrared sensor 24 will send a signal. After receiving the signal, the controller 25 will control the electric push rod II 19 to drive the slide 20 to stop moving. Then the controller 25 will control the air pump 22 to extract the air in the air bag I 21 through the air pipe I 23, so that the air bag I 21 shrinks, so that the air bag I 21 shrinks and puts down the patient's legs, thereby The patient's legs are parked at the designated position directly below the connecting frame 9, and then the controller 25 controls the electric push rod II 19 to drive the carriage 20 to continue to move to the side close to each other and reset, so that the carriage 20 is separated from the patient's legs, and then the telescopic rod of the electric push rod I 2 is shortened to move the machine 1 downward and reset, so that the machine 1 drives the rotating shaft 4, the gear ring 7, the connecting rod 8, the connecting frame 9, the sliding plate 10, the splint I 11 and the splint II 12 to move downward, until the patient's calf is between the two splints I 11 on the connecting frame 9 and the sliding plate 10, and the patient's foot is between the two splints II 12 on the connecting frame 9 and the sliding plate 10, and then the reduction motor 17 drives the screw rod 18 to rotate, so that the sliding plate 10 is between the connecting frame 9 and the sliding plate 10. The two splints Ⅰ11 on the connecting frame 9 and the sliding plate 10 are gradually moved closer until the two splints Ⅰ11 clamp the patient's calves. At the same time, the two splints Ⅱ12 on the connecting frame 9 and the sliding plate 10 are also gradually moved closer until the two splints Ⅱ12 clamp the patient's feet. Then the telescopic rod of the electric push rod Ⅰ2 is controlled to extend to move the machine 1 upward, thereby driving the rotating shaft 4, the gear ring 7, the connecting rod 8, the connecting frame 9, the sliding plate 10, the splints Ⅰ11 and the splints Ⅱ12 to move upward, and then driving the patient's legs to be lifted up, and then the electromagnet 14 on the left or right side is energized, so that the electromagnet 14 on the left or right side uses magnetic force to drive the iron plate 13 on the left or right side to move downward, thereby moving the tooth block 5 on the left or right side downward,The spring 6 on the left or right side is compressed, so that the tooth block 5 on the left or right side releases the corresponding tooth ring 7, and then the servo motor 15 on the left or right side drives the gear 16 to rotate 180 degrees, so that the gear 16 on the left or right side drives the corresponding tooth ring 7 to rotate 180 degrees, so that the connecting rods 8 on the left and right sides face opposite directions respectively, and then the electromagnet 14 on the left or right side is powered off, the spring 6 on the left or right side is restored to its original state, and the spring 6 on the left or right side drives the corresponding tooth block 5 and the iron plate 13 to move upward and reset, so that the tooth block 5 on the left or right side re-locks the corresponding tooth ring 7, and then the next step is performed according to the needs. If no auxiliary is required When the patient is training, the patient's feet are made to perform bicycle riding movements, so that the patient can perform rehabilitation training on the bed. At the same time, when the patient is training, the patient's feet will drive the connecting rod 8, the gear ring 7 and the rotating shaft 4 to rotate (because the servo motor 15 does not have a self-locking function, the rotation of the gear ring 7 will not be affected by the gear 16 of the servo motor 15); if the patient needs to be assisted in training, the servo motor 15 drives the gear 16 to rotate slowly, so that the gear 16 drives the gear ring 7, the rotating shaft 4 and the connecting rod 8 to rotate slowly, thereby driving the patient's feet to slowly perform bicycle riding movements, thereby assisting the patient in performing rehabilitation training on the bed;, After the patient's feet have completed the rehabilitation training, the electromagnet 14 on the left or right side is energized, so that the electromagnet 14 on the left or right side uses magnetic force to drive the iron plate 13 on the left or right side to move downward again, so that the tooth block 5 on the left or right side moves downward, and the spring 6 on the left or right side is compressed, so that the tooth block 5 on the left or right side releases the corresponding gear ring 7, and then the servo motor 15 on the left or right side drives the gear 16 to reverse 180 degrees and reset, so that the gear 16 on the left or right side drives the corresponding gear ring 7 to rotate 180 degrees, so that the left and right sides The connecting rods 8 are all facing the same direction (all facing downward), and then the electromagnet 14 on the left or right side is de-energized, and the spring 6 on the left or right side is restored to its original state, and the spring 6 on the left or right side drives the corresponding tooth block 5 and the iron plate 13 to move upward and reset, so that the tooth block 5 on the left or right side re-locks the corresponding gear ring 7, and then controls the telescopic rod of the electric push rod Ⅰ2 to shorten, so that the machine 1 moves downward and resets, thereby driving the rotating shaft 4, the gear ring 7, the connecting rod 8, the connecting frame 9, the sliding plate 10, the splint Ⅰ11 and the splint Ⅱ12 to move downward, and then drives the patient's legs to move upward. The machine 1 moves downward, and then the reduction motor 17 drives the screw rod 18 to reverse and reset, so that the sliding plate 10 slides and resets in the connecting frame 9, so that the two splints Ⅰ11 on the connecting frame 9 and the sliding plate 10 gradually move away from each other, until the two splints Ⅰ11 release the patient's calf, and at the same time, the two splints Ⅱ12 on the connecting frame 9 and the sliding plate 10 will also gradually move away from each other, until the two splints Ⅱ12 release the patient's sole, and then control the telescopic rod of the electric push rod Ⅰ2 to extend, so that the machine 1 moves upward, thereby driving the rotating shaft 4, the gear ring 7, the connecting rod 8, the connecting frame 9, and the sliding plate 10. Splint I11 and splint II12 move upward, so that the patient's calf leaves from between the two splints I11 on the connecting frame 9 and the sliding plate 10, and the patient's foot leaves from between the two splints II12 on the connecting frame 9 and the sliding plate 10. Then, the patient's legs on the bed are spread open, and the telescopic rod of the electric push rod I2 is controlled to shorten, so that the machine 1 moves downward and resets, thereby driving the rotating shaft 4, the gear ring 7, the connecting rod 8, the connecting frame 9, the sliding plate 10, the splint I11 and the splint II12 to move downward and reset, and then the support plate 3 can be taken away from the bed.

[0033] See also Figure 7-Figure 9As shown, it also includes a wrapping mechanism, which includes airbag II 26, airbag III 27, air cylinder 28, movable plate 29, connecting rod 30, trachea II 31, trachea III 32 and piezoelectric film sensor 33; airbag II 26 is arranged on splint I 11; airbag III 27 is arranged on splint II 12; air cylinder 28 is installed on connecting frame 9; movable plate 29 is slidably arranged on the inner side of air cylinder 28; two ends of connecting rod 30 are respectively connected to movable plate 29 and sliding plate 10; trachea II 31 is connected between airbag II 26 connected to splint I 11 of sliding plate 10 and air cylinder 28; trachea III 32 is connected between airbag II 26 and airbag III 27; piezoelectric film sensor 33 is installed on airbag II 26 connected to splint I 11 of connecting frame 9, piezoelectric film sensor 33 is electrically connected to controller 25, and piezoelectric film sensor 33 is used to sense the pressure on the patient's legs.

[0034] When the sliding plate 10 slides in the connecting frame 9, the connecting frame 9 will drive the connecting rod 30 and the movable plate 29 to move, so that the movable plate 29 squeezes the air in the air reservoir 28, so that the air in the air reservoir 28 enters the airbags II 26 and III 27 through the trachea II 31 and the trachea III 32, and then the airbags II 26 and III 27 gradually expand. When the two splints I 11 on the connecting frame 9 and the sliding plate 10 gradually approach, the airbag II 26 on the splint I 11 will gradually clamp the patient's calf. At the same time, when the two splints II 12 on the connecting frame 9 and the sliding plate 10 gradually approach, the airbag III 27 on the splint II 12 will gradually clamp the patient's foot. In this way, the patient's calf and foot are clamped by the airbags II 26 and III 27. The airbag II 26 on the splint I 11 can wrap the patient's calf and sole, thereby improving the comfort of the patient's calf and sole; when the airbag II 26 on the splint I 11 clamps the patient's calf, the patient's calf will come into contact with the piezoelectric film sensor 33, and the patient's calf will continue to apply pressure to the piezoelectric film sensor 33. When the piezoelectric film sensor 33 senses that the pressure is greater than the preset value, the piezoelectric film sensor 33 sends a signal. After receiving the signal, the controller 25 controls the reduction motor 17 to stop driving the screw rod 18 to rotate, so that the sliding plate 10 stops sliding in the connecting frame 9, so that the airbag II 26 on the splint I 11 stops continuing to clamp the patient's calf, so as to prevent the airbag II 26 on the splint I 11 from clamping the patient's calf too tightly and avoiding damage to the patient's calf. When the sliding plate 10 slides and resets in the connecting frame 9, the connecting frame 9 will drive the connecting rod 30 and the movable plate 29 to move and reset, so that the movable plate 29 draws the air in the airbags II 26 and the airbags III 27 back into the air storage cylinder 28 through the trachea II 31 and the trachea III 32, thereby gradually shrinking the airbags II 26 and the airbags III 27; when the two splints I 11 on the connecting frame 9 and the sliding plate 10 gradually move away from each other, the airbag II 26 on the splint I 11 will gradually loosen the patient's calf, and at the same time, when the two splints II 12 on the connecting frame 9 and the sliding plate 10 gradually move away from each other, the airbag III 27 on the splint II 12 will gradually loosen the patient's foot.

[0035] The above description is only a specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
