The rotating shaft 34 is connected to a calf support plate 35 located outside the cylinder 33, and the calf support plate 35 is located in the installation groove 21. The shape of the calf support plate 35 is L-shaped, and the tops of the thigh support plate 32 and the calf support plate 35 are connected to arc-shaped airbags 36. An arc-shaped slider 37 is slidably provided in the arc shell 31, and the arc-shaped slider 37 is fixedly connected to the thigh support plate 32. The rotating shaft 34 is connected to the cylinder 33. The rotating plate 38 contacts the inner wall of the cylinder 33, a baffle 39 in contact with the rotating shaft 34 is connected to the cylinder 33, an air hole 310 is opened on the cylinder 33 and is located on the lower side of the baffle 39, a delivery and suction assembly is provided at the bottom of the bed board 2, and the delivery and suction assembly includes an air delivery pump 311 and an air extraction pump 319 installed at the rear side of the bottom of the bed board 2, the air delivery pump 311 is located on the left side of the air extraction pump 319, a through port 12 for accommodating the air delivery pump 311 and the air extraction pump 319 is opened at the rear side of the top of the bed frame 1, and a hose 312 is connected to the arc shell 31, and the hose 312 is connected to the bottom of the bed board 2. A solenoid valve 1 313 is installed, a hose 2 314 is connected to the cylinder 33, a solenoid valve 2 315 is installed on the hose 2 314, a hose 316 is connected between the two arc-shaped air bags 36 on the left and between the two arc-shaped air bags 36 on the right, a solenoid valve 317 is installed on the hose 316, the air delivery pump 311 is connected to the hose 1 312, the hose 2 314 and the hose 3 316 through the air delivery branch pipe 318, and the air extraction pump 319 is connected to the hose 1 312, the hose 2 314 and the hose 3 316 through the air extraction branch pipe 320.

[0033] When the child wants to do leg lifting training, he / she lies on the bed board 2, places the thigh and calf on the thigh support board 32 and the calf support board 35 respectively, and places the leg in the arc-shaped airbag 36. First, the electromagnetic valve 317 on the two hoses 316 is controlled to open, and then the air delivery pump 311 is controlled to work, and the gas is injected into the arc-shaped airbag 36 through the hose 316 through the gas delivery branch pipe 318, so that the arc-shaped airbag 36 expands, the arc-shaped airbag 36 on the thigh support board 32 expands to fix the thigh on the thigh support board 32, and the arc-shaped airbag 36 on the calf support board 35 expands to fix the calf on the thigh support board 32 (see Figure 1). Then, the solenoid valve 1 313 on the left hose 1 312 is controlled to open, and the solenoid valves 3 317 on the two hoses 3 316 are controlled to close, so that gas is injected into the left arc shell 31 through the left hose 1 312, and the left arc slider 37 is pushed out of the left arc shell 31 by the gas, so that the left thigh support plate 32 rotates upward with the left arc shell 31 as the rotation center, and the left calf support plate 35 rotates upward with the left thigh support plate 32, thereby pushing the left leg to be lifted upward (see Figure 6 ). By controlling the air delivery pump 311 to be closed and controlling the air extraction pump 319 to work, the gas in the left arc shell 31 can be extracted outward through the left hose 1 312 and the air extraction branch pipe 320, so that the left arc slider 37 moves back into the left arc shell 31, so that the left thigh support plate 32 drives the left calf support plate 35 to rotate downward and reset with the left arc shell 31 as the rotation center, and then the left leg is put down. Similarly, by controlling the vacuum pump 319 and the solenoid valve 313 on the left hose 312 to close, and controlling the solenoid valve 313 on the right hose 312 to open, and controlling the air pump 311 to operate, the right thigh support plate 32 can drive the right calf support plate 35 to rotate upward, thereby lifting the right leg upward; then, the air pump 311 is controlled to close, and the vacuum pump 319 is controlled to operate, so that the right thigh support plate 32 can drive the right calf support plate 35 to rotate downward to lower the right leg; repeating the above operations can make the two legs alternately lift and lower, thereby realizing leg lifting training for children.

[0034] If the leg-lifting and knee-bending training is to be performed, the above-mentioned operation is repeated. First, the thigh support plate 32 drives the calf support plate 35 to rotate upward to lift the leg. Then, the solenoid valve 1 313 on the control hose 1 312 is closed. Then, the solenoid valve 2 315 on the control hose 2 314 is opened, so that the air pump 311 injects gas into the cylinder 33 through the hose 2 314. The baffle 39 can block the gas to prevent the gas injected into the cylinder 33 from being discharged from the air hole 310, so that the gas pushes the rotating plate 38 to rotate downward with the rotating shaft 34 as the rotation center, so that the rotating shaft 34 drives the calf support plate 35 to rotate downward. The calf support plate 35 rotates downward to pull the calf downward through the arc-shaped airbag 36 to perform the leg-lifting and knee-bending training (see Figure 7 ), the rotating plate 38 rotates downward to push the original gas in the cylinder 33 out from the air hole 310, ensuring that the rotating plate 38 rotates smoothly. Then the air delivery pump 311 is controlled to be closed, and the air extraction pump 319 is controlled to work, and the gas in the cylinder 33 is extracted outward through the hose 2 314, so that the rotating plate 38 rotates upward and resets with the rotating shaft 34 as the rotation center, so that the rotating shaft 34 drives the calf support plate 35 to rotate upward and reset to support the calf, and finally put the whole leg down. Similarly, the two legs are alternately lifted and bent, so as to achieve the leg lifting and knee bending training for children.

[0035] If walking training is to be performed, the medical staff first moves the bed board 2 backward and raises it to a vertical state, and then allows the child to stand on the L-shaped calf support board 35 (see FIG. Figure 2 ), then repeat the same operation of the above-mentioned leg-lifting and knee-bending training. The child stands and performs the leg-lifting and knee-bending exercises alternately (see Figure 8 ), it can simulate walking movements and realize walking training for children. In this way, the rehabilitation bed can not only assist children in leg-lifting training, but also assist children in leg-lifting and knee-bending training, and can also assist children in walking training, thereby effectively liberating medical staff, not only significantly reducing the workload of medical staff, but also providing children with more personalized and efficient rehabilitation exercises, and promoting children's rehabilitation. After the training is completed, the solenoid valve 317 on the control hose 316 is opened, and then the gas in the arc-shaped airbag 36 can be extracted through the air pump 319, so that the arc-shaped airbag 36 contracts and loosens the child's legs.

[0036] See 9- Fig.12 The bed board 2 is provided with a fixing mechanism for fixing the child's arm, the fixing mechanism includes a U-shaped positioning rod 41, a conical top block 42, a contact rod 43, a block 44 and a spring 45, and the bed board 2 is provided with two left and right groups of jacks 23, each group of jacks 23 has two, and the two jacks 23 in each group are arranged front and back, and each group of jacks 23 is inserted with a U-shaped positioning rod 41 for fixing the child's arm, and the bed board 2 is provided with two left and right cross-shaped slide grooves 24, the cross-shaped slide grooves A conical top block 42 is slidably connected in the groove 24, and two contact rods 43 are slidably connected in the cross-shaped slide groove 24 with the conical top block 42 as the symmetry center. A clamping block 44 is connected to the side of the contact rod 43 away from the conical top block 42, and a clamping groove 46 matching the clamping block 44 is formed on the front and rear sides of the U-shaped positioning rod 41. A spring 45 located in the cross-shaped slide groove 24 is sleeved on the contact rod 43, and the two ends of the spring 45 are respectively connected to the contact rod 43 and the bed board 2.

[0037] After the child lies on the bed board 2, the child's arm is extended into the U-shaped positioning rod 41. When the bed board 2 is in a horizontal state and fits on the bed frame 1, the conical top block 42 is lifted up by the bed frame 1, and the conical top block 42 squeezes the front and rear contact rods 43 away from each other, the spring 1 45 is compressed, and the block 44 is located on the outside of the U-shaped positioning rod 41. When the bed board 2 drives the conical top block 42 to rise backward and upward and separate from the bed frame 1, under the reset action of the spring 1 45, the contact rod 43 is pushed to move in the direction close to the conical top block 42 to squeeze the conical top block 42 to move backward, and the contact rod 43 moves in the direction close to the conical top block 42 with the block 44 to move into the card slot 46 on the U-shaped positioning rod 41 to lock the U-shaped positioning rod 41, and the child's arm and shoulder can be fixed through the U-shaped positioning. In this way, when the bed board 2 is raised to allow the child to stand up for walking training, the child's arm and shoulder can be fixed to prevent the child from falling, thereby improving the safety of the child's walking training. When the bed board 2 drives the conical top block 42 to move forward and downward and contact the bed frame 1, the conical top block 42 continues to be pushed upward by the bed frame 1, and the conical top block 42 moves upward to squeeze the two contact rods 43 away from each other, compressing the spring 1 45 to push the block 44 out of the slot 46 on the U-shaped positioning rod 41, thereby releasing the lock on the U-shaped positioning rod 41 to facilitate the subsequent child to get up.

[0038] See also Fig. 9 The bed frame 1 is provided with a lifting mechanism for lifting the bed board 2, and the lifting mechanism includes a cylinder 51, a push rod 52 and a connecting ring 53. The left rear side and the right rear side of the bed frame 1 are both installed with cylinders 51, and the telescopic rods of the two cylinders 51 are connected with connecting rings 53. A push rod 52 is rotatably penetrated on the rear side of the bed board 2, and the push rod 52 is connected to the two connecting rings 53.

[0039] The telescopic rod of the control cylinder 51 is extended, so that the connecting ring 53 pushes the push rod 52 to move upward, and the upward movement of the push rod 52 drives the rear side of the bed board 2 to rise upward, and the bed board 2 slides backward accordingly. The telescopic rod of the control cylinder 51 is shortened, so that the connecting ring 53 pulls the push rod 52 to move downward, and the downward movement of the push rod 52 drives the bed board 2 to descend, and the bed board 2 slides forward and resets to achieve automatic lifting and lowering of the bed board 2, thereby eliminating the need for medical staff to manually lift the bed board 2, which can save time and effort and further reduce the workload of medical staff.

[0040] See also Figure 3A roller 61 is rotatably connected to the guide rod 22, and a roller 2 62 is rotatably connected to the bottom of the L-shaped calf support plate 35. The roller 61 can reduce the friction between the bed board 2 and the bed frame 1, so that the bed board 2 can slide more smoothly on the bed frame 1, so as to reduce the wear between the bed board 2 and the bed frame 1, and extend the service life of the bed board 2 and the bed frame 1. The roller 2 62 can reduce the friction between the calf support plate 35 and the bed frame 1, so that the calf support plate 35 can slide more smoothly on the bed frame 1, so as to reduce the wear between the calf support plate 35 and the bed frame 1, and extend the service life of the calf support plate 35 and the bed frame 1.

[0041] See also Fig.13 A push block 72 is slidably connected to the rear side of the guide groove 11, and two left and right springs 71 are connected between the rear side of the push block 72 and the bed frame 1.

[0042] When the bed board 2 slides backward and rises upward, the guide rod 22 drives the roller 1 61 to slide backward and contact the push block 72, and then the roller 1 61 continues to move backward to push the push block 72 backward, compressing the spring 2 71. When the telescopic rod of the cylinder 51 contracts to make the bed board 2 move downward and slide forward, the guide rod 22 drives the roller 1 61 to slide forward, and under the reset action of the spring 2 71, the push block 72 is pushed forward, and then the roller 1 61 is pushed forward. The roller 1 61 slides forward and pulls the bed board 2 forward through the guide rod 22, so that the cooperation of the spring 2 71 and the push block 72 can assist the bed board 2 to smoothly complete the action of sliding forward and moving downward, effectively reducing the risk of the bed board 2 getting stuck.

[0043] See also Fig.13 The left and right side surfaces of the bed board 2 are provided with two front and rear plug holes 25 matching the U-shaped positioning rod 41, and the U-shaped positioning rod 41 is connected with a U-shaped rubber rod 8.

[0044] The U-shaped rubber rod 8 can provide buffer protection for children to prevent them from being strangled by the U-shaped positioning rod 41, thereby improving the comfort of fixation. After the U-shaped positioning rod 41 is pulled out from the first socket 23 to release the child, the U-shaped positioning rod 41 can be inserted into the second socket 25 to facilitate subsequent access to the U-shaped positioning rod 41.

[0045] See also Figure 1-Figure 2 A cantilever bracket 91 is connected to the left rear side of the top of the bed board 2, and a player 92 is installed on the cantilever bracket 91.

[0046] The medical staff turns on the player 92, and the player 92 plays music or animation to attract the child's attention, thereby assisting the child in rehabilitation exercises. The cantilever bracket 91 can be adjusted at any angle, so that the player 92 can be adjusted to the best viewing angle according to the needs of the child. The cantilever bracket 91 that can be adjusted at any angle is a prior art and will not be described in detail here.
