The second contact button 106 is installed on the right rear side of the first bed frame 2 by screws, and the second rotating plate 85 can contact the second contact button 106.

[0044] When it is necessary to protect the patient, the accompanying personnel can press the main power switch to power on the medical bed. Initially, since the protective plates 64 on the left and right sides are located in the middle position of the first bed frame 2, when the accompanying personnel needs to move the protective plates 64 to the front side, they can press the first start button 61, and the first start button 61 sends a signal. After receiving the signal, the control module will simultaneously control the two first drive motors 65 to rotate, and the first drive motor 65 will drive the gear 66 to rotate, and the gear 66 and the rack 67 will mesh with each other to push the protective plate 64 to move forward. When the distance sensor 68 senses that the protective plate 64 moves to the preset position to the front side, the distance sensor 68 will send a signal to the control module, and the control module will control the first drive motor 65 to stop rotating. When the accompanying personnel needs to move the protective plate 64 to the back side, they can press the second start button 62, and the second start button 62 sends a signal, and the control module receives the signal. After receiving the signal, the two output shafts of the first drive motors 65 will be controlled to rotate in the opposite direction at the same time. The first drive motor 65 will drive the gear 66 to rotate in the opposite direction. Under the meshing action of the gear 66 and the rack 67, the protective plate 64 will be pushed to move backward. When the distance sensor 68 senses that the protective plate 64 moves backward to the preset position, the distance sensor 68 will send a signal to the control module, and the control module will control the first drive motor 65 to stop rotating. When the patient needs to move the protective plate 64 to the middle, the reset button 63 can be pressed. The reset button 63 sends a signal. After receiving the signal, the control module will control the first drive motor 65 to rotate again. Under the meshing action of the gear 66 and the rack 67, the protective plates 64 on the left and right sides are moved to the middle and reset. Under the blocking action of the protective plate 64, the patient can be prevented from rolling off the first bed frame 2, which can provide a certain protection for the patient and improve the safety of the use of the medical bed.When the caregiver needs to take a rest, he / she can press the second contact button 106, and the second contact button 106 sends a signal. After receiving the signal, the control module will simultaneously control the output shafts of the two second drive motors 102 to rotate, and the second drive motor 102 will drive the winding wheel 103 to rotate to reel in the first pull rope 105. Under the pulling action of the first pull rope 105, the sliding rod 71 will move along the first support frame 1 to the first contact button 711, and the second support frame 72, the second bed frame 73, the second roller 74, the first rotating plate 75, the rotating block 76, the mounting block 77, the electric push rod 78 and the first connecting block 79 will also move to the first contact button 711. When the sliding rod 71 contacts the first contact button 711, the first contact button 711 sends a signal to the control module, and the control module will simultaneously control the two electric push rods 78 works, and when the telescopic shaft on the front side electric push rod 78 is extended for 3 seconds, it will stop working, so that the first connecting block 79 on the front side moves toward the first rotating plate 75. When the first connecting block 79 on the front side contacts the first rotating plate 75, the first rotating plate 75 will flip upward by about 90 degrees and maintain the same horizontal position with the second bed board frame 73. At the same time, when the telescopic shaft on the rear side electric push rod 78 is extended for 3 seconds, it will also stop working, so that the first connecting block 79 on the rear side moves toward the rotating block 76. When the first connecting block 79 on the rear side contacts the rotating block 76, the rotating block 76 will flip upward by about 90 degrees and maintain the same horizontal position with the second bed board frame 73. In this way, when the first rotating plate 75 and the rotating block 76 are unfolded at the same time, the area of ​​the second bed board frame 73 can be increased, which is convenient for the accompanying personnel to have a better rest and increase the comfort. When the accompanying person has finished resting, the second contact button 106 can be activated again, and the second contact button 106 will send a signal to the control module, which will control the second drive motor 102 to rotate in the opposite direction, and the winding wheel 103 will rotate in the opposite direction to loosen the first pull rope 105. At this time, the accompanying person can push the second bed frame 73 to slide inward and reset. When the sliding rod 71 is disengaged from the first contact button 711, the first contact button 711 will send a signal to the control module, and the control module will simultaneously control the two electric push rods 78 to close, and the telescopic shaft of the electric push rod 78 will drive the first connecting block 79 thereon to shorten and reset, so that the front and rear first connecting blocks 79 can be retracted and reset. Block 79 is disengaged from the rotating block 76 and the first rotating plate 75 respectively, and will flip downward and reset under the action of their own gravity. When the sliding rod 71 slides inward to the extreme position, the second support frame 72, the second bed frame 73, the second roller 74, the first rotating plate 75, the rotating block 76, the mounting block 77, the electric push rod 78 and the first connecting block 79 all slide inward and reset. The second contact button 106 is pressed, and the second contact button 106 sends a signal to the control module. The control module will control the second drive motor 102 to turn off, and the first pull rope 105 will be in a straightened state. The accompanying personnel can turn off the main power switch.

[0045] Embodiment 2:

[0046] On the basis of Example 1, Figure 1 , Figure 2 , Fig.10 , Fig.11 and Fig.12 As shown, it also includes a sliding mechanism 8, which includes a first fixed rod 81, a second fixed rod 82, a second connecting block 83, a pulley 84, a second rotating plate 85, a first return spring 86 and an electromagnet 87. The first fixed rod 81 is welded between the front and rear sides of the middle part of the right side of the first support frame 1, and the rear side of the first fixed rod 81 is slidably provided with a second connecting block 83. The rear side of the first fixed rod 81 is sleeved with a first return spring 86, and the two ends of the first return spring 86 are respectively connected to the rear end surface of the second connecting block 83 and the first support frame 1, an electromagnet 87 is installed on the front side of the first fixed rod 81 by screws, and the second fixed rod 82 is welded on the right side of the second connecting block 83. The top of the second fixed rod 82 is rotatably provided with a second rotating plate 85, and the bottom of the second fixed rod 82 is rotatably provided with two pulleys 84 through a fixed seat.

[0047] like Figure 1 , Figure 2 and Fig.12 As shown, a clamping mechanism 9 is also included, which includes a fixed block 91, a torsion spring 92, a limit rod 93 and an elastic member 94. The upper part of the second fixed rod 82 is riveted with a fixed block 91, and a torsion spring 92 is connected between the upper end surface of the fixed block 91 and the lower end surface of the second rotating plate 85. A limit rod 93 is slidably provided on the fixed block 91, and at least two grooves are provided at the bottom of the second rotating plate 85. The lower part of the limit rod 93 is sleeved with an elastic member 94, and the two ends of the elastic member 94 are respectively connected to the lower end surface of the fixed block 91 and the limit rod 93.

[0048] When the patient needs to have a meal, the accompanying staff can turn on the main power switch to power on the medical bed. The accompanying staff can push the limit rod 93 to slide downward so that the limit rod 93 is disengaged from the groove on the second rotating plate 85, and the elastic member 94 is stretched accordingly. At the same time, the second rotating plate 85 is rotated to a suitable position, and the torsion spring 92 is deformed accordingly. When the second rotating plate 85 is rotated to a suitable position, the limit rod 93 is released, and the elastic force of the elastic member 94 drives the limit rod 93 to slide upward and reset, so that the limit rod 93 can be separated from the other side. The groove snap-fitting at one place can limit the second rotating plate 85 to prevent the second rotating plate 85 from rotating during the patient's use. The accompanying person can push the second rotating plate 85 to move toward the electromagnet 87, and the second fixing rod 82, the second connecting block 83, the pulley 84, the fixing block 91, the torsion spring 92, the limiting rod 93 and the elastic member 94 all slide toward the electromagnet 87, and the first return spring 86 is stretched accordingly. When the second connecting block 83 contacts the electromagnet 87, the electromagnet 87 has magnetism after being energized, and the first return spring 86 is stretched. The second connecting block 83 is made of iron, so the electromagnet 87 can attract the second connecting block 83, so that the second fixing rod 82 and the second rotating plate 85 can be limited, which is convenient for the patient to eat. When the second rotating plate 85 is not needed, the main power switch can be turned off. When the electromagnet 87 is turned off, the electromagnet 87 will lose its magnetism, and the accompanying personnel can hold the second rotating plate 85 with their hands and slowly relax it. Under the action of the pulling force of the first reset spring 86, the second connecting block 83 will slide backward and reset, and the second fixing rod 82, the pulley 84, and the second rotating plate 85 can be turned off. 5. The fixing block 91, the torsion spring 92, the limiting rod 93 and the elastic member 94 all slide backward. When the patient needs to rest, the accompanying person can press the limiting rod 93 downward again, so that the limiting rod 93 can be disengaged from the groove on the second rotating plate 85. Under the action of the elastic force of the torsion spring 92, the second rotating plate 85 will be driven to flip outward about 180 degrees, so that the second rotating plate 85 can contact the second contact button 106. When the medical bed is powered on, the second contact button 106 will send a signal to the control module, and the control module will control the deployment mechanism 7 to open automatically.

The rear side of the guide rail 111 is sleeved with a second return spring 113, and the two ends of the second return spring 113 are respectively connected to the rear end surface of the pedal 112 and the guide rail 111. A groove wheel 114 is rotatably provided at the middle position of the left rear side of the first support frame 1 through a mounting rod, and a second pull rope 115 is connected between the upper part of the pedal 112 and the bottom of the left protective plate 64, and the second pull rope 115 is wrapped around the groove wheel 114.

[0051] When the patient needs to get out of bed, when the medical bed is powered on, the accompanying person can press the second start button 62, and the second start button 62 sends a signal. After receiving the signal, the control module will simultaneously control the two first drive motors 65 to rotate in the opposite direction, and the first drive motor 65 will drive the gear 66 to rotate in the opposite direction. Under the meshing action of the gear 66 and the rack 67, the protective plate 64 will be pushed to move backward. In the process of the protective plate 64 sliding backward, the protective plate 64 loosens the second pull rope 115. Initially, because the second return spring 113 is in a compressed state, the pedal 112 is driven to slide along the middle part of the guide rail 111 under the action of the thrust of the second return spring 113. When the distance sensor 68 senses that the protective plate 64 moves backward to the preset position, the distance sensor 68 will send a signal to the control module. The control module will control the first drive motor 65 to stop rotating, so that the patient can step on the pedal 112, which can provide certain assistance to the patient and facilitate the patient to get in and out of bed. When the patient does not need to use the pedal 112, the caregiver can press the reset button 63, and the reset button 63 sends a signal. After receiving the signal, the control module will control the first drive motor 65 to rotate, and under the meshing action of the gear 66 and the rack 67, the protective plates 64 on the left and right sides move toward the middle and reset. In the process of the protective plates 64 sliding toward the middle, the protective plates 64 will pull the second pull rope 115 to move toward the middle. Under the guidance of the groove wheel 114, the second pull rope 115 will pull the pedal 112 to slide to the rear side and reset, and the second reset spring 113 will be compressed accordingly, and the caregiver can turn off the main power switch.

[0052] like Figure 1 , Figure 2 , Fig.17 and Fig.18As shown, a control box 5 is also included. The control box 5 is installed on the right front side of the first bed frame 2. A switching power supply, a control module and a power module are installed in the control box 5. The switching power supply supplies power to the entire medical bed. The output end of the switching power supply is electrically connected to the power module. The power module is connected to a main power switch through a line. The control module and the power module are electrically connected. The control module is connected to a DS1302 clock circuit and a 24C02 circuit. The first start button 61, the second start button 62, the reset button 63, the first contact button 711, the second contact button 106 and the distance sensor 68 are all electrically connected to the control module. The first drive motor 65, the second drive motor 102, the electric push rod 78 and the electromagnet 87 are all connected to the control module through a peripheral circuit.
