[0032] The first motor 6 is fixedly connected to the inner wall of the bottom end of the support box 4, and a threaded rod 7 is fixedly connected to the output end of the first motor 6. A threaded seat 8 slidably connected to the support box 4 is threadedly connected to the outer surface of the threaded rod 7. Two extension plates 9 are fixedly connected to the front end surface of the threaded seat 8. A long pin 10 is fixedly connected to the inner wall of the front end of the two extension plates 9. A long rotating shaft 13 is rotatably connected to the inner wall of the support box 4. A driving rod 11 is fixedly connected to the outer surface of the long rotating shaft 13. The driving rod 11 is provided with a first long key groove 12 that matches the long pin 10.

[0033] like Figure 3-Figure 4As shown, the function of the first motor 6 is to provide rotational force for the threaded rod 7. The motor is a prior art and will not be described in detail. A bearing seat is rotatably connected to the outer surface of the threaded rod 7. The bottom end of the bearing seat is fixed to the upper end surface of the support box 4. The bearing seat can limit the threaded rod 7 to only rotate, which is equivalent to the threaded rod 7 being rotatably connected to the support box 4. The threaded seat 8 can be slidably connected to the inner wall of the support box 4 back and forth, and the extension plate 9 supports and limits the long pin 10. The installation and shape of the drive rod 11, the first long key groove 12, and the long pin 10 are as shown in FIG. Figure 4 As shown, when the long pin 10 moves forward or backward, the driving rod 11 can be flipped forward under the engagement of the first long key groove 12 and the long pin 10. When the driving rod 11 flips forward, it will drive the corresponding long rotating shaft 13 to rotate, that is, drive the long rotating shaft 13 to rotate forward and reversely; when the first motor 6 is started, it can drive the corresponding threaded rod 7 to rotate. When the threaded rod 7 rotates, it can drive the threaded seat 8, the extension plate 9, and the long pin 10 to move forward or backward synchronously through the threaded connection with the threaded seat 8. When the long pin 10 moves forward, it will drive the corresponding driving rod 11 to swing forward and the long rotating shaft 13 to rotate. In addition, the threaded connection between the threaded rod 7 and the threaded seat 8 has a self-locking function, that is, when the long rotating shaft 13 rotates to the specified position and stops, the corresponding long rotating shaft 13 will not rotate if the threaded rod 7 does not rotate.

[0034] A multi-stage telescopic rod 17 is fixedly connected to the front side of the inner wall at the bottom end of the support box 4, and a tray 18 is fixedly connected to the upper end surface of the multi-stage telescopic rod 17. Two driven rods 14 are also fixedly connected to the outer surface of the long rotating shaft 13. Second sliding pins 16 are respectively fixedly connected to the left and right sides of the upper end of the outer surface of the multi-stage telescopic rod 17, and the driven rods 14 are respectively provided with second long key grooves 15 that match the second sliding pins 16; a through hole 34 that matches the tray 18 is provided on the upper end surface of the middle bed board 19, and a pick-up and placement groove 5 is respectively provided on the left and right end surfaces of the support box 4.

[0035] like Figure 4 or Figure 7 As shown, the multi-stage telescopic rod 17 can limit the tray 18 to move up and down, and the through hole 34 can be sealed when the tray 18 moves upward to the top, and when it moves downward, the through hole 34 is opened to facilitate the defecation of the elderly; when the tray 18 moves downward to the bottom, the placement groove 5 is provided to facilitate the placement or removal of the toilet bucket; the driven rod 14, the second long key groove 15, the second sliding pin 16, and the multi-stage telescopic rod 17 are installed and shaped as shown in FIG. Figure 4 As shown, when the driven rod 14 flips downward, the second sliding pin 16 engages with the second long key groove 15, which drives the corresponding multi-stage telescopic rod 17 and the tray 18 to move downward. When the driven rod 14 flips upward, the corresponding tray 18 is driven to move upward. Therefore, when the long rotating shaft 13 rotates, it can drive the corresponding tray 18 to move upward or upward.

[0036] A short lever 25 and a long lever 26 are also fixedly connected to the outer surface of the long rotating shaft 13, and a first lever pin 29 is fixedly connected to the inner wall of the upper end of the short lever 25. The rear bed board 20 is hinged to the rear end surface of the middle bed board 19, and a first limiting plate 27 is fixedly connected to the lower end surface of the rear bed board 20.

[0037] like Figure 5-Figure 7 As shown, there are two long levers 26, which are respectively arranged at the left and right ends of the long rotating shaft 13. Through the engagement of the first lever pin 29 with the first limiting groove, when the short lever 25 flips upward, it can drive the first limiting plate 27 and the rear bed board 20 to flip upward. Through the engagement of the second lever pin 30 with the second limiting groove, when the long lever 26 flips downward, it can drive the corresponding second limiting plate 28 and the front bed board 22 to flip downward. Therefore, when the long rotating shaft 13 rotates, it can drive the short lever 25 to flip upward and the long lever 26 to flip downward. When the short lever 25 flips upward, it can drive the rear bed board 20 to flip upward. When the long lever 26 flips downward, it can drive the front bed board 22 to flip downward, thereby assisting the elderly to get up and sit.

[0038] The front and rear sides of the lower end surface of the rear bed board 20 are respectively fixed with baffles 35 that cooperate with the flap 21. The flap 21 is hinged on one end surface of the rear bed board 20. The upper end surface of the support box 4 is fixed with two first telescopic rods 36, and the top rod 37 is fixed to the upper ends of the two first telescopic rods 36.

[0039] like Figure 8 As shown, the baffle plate 35 is set to limit the flap 21, that is, the limited flap 21 is flipped downward to the maximum position flush with the rear bed board 20. When the rear bed board 20 is flipped upward, the flap 21 is driven to flip upward synchronously through the support of the baffle plate 35, and the flap 21 can be flipped to the upper end side under the hinge of the rear bed board 20; the first telescopic rod 36 can drive the push rod 37 to move up and down, and the telescopic rod can be an electric telescopic rod or a pneumatic rod. The telescopic rod is a prior art and will not be described in detail; when the rear bed board 20 and the flap 21 are in a horizontal state and act as a bed board, when the first telescopic rod 36 is working, it can drive the push rod 37 to move upward or downward. When the push rod 37 moves upward, it will lift the flap 21 to flip upward, thereby assisting the elderly to turn over and prevent pressure sores on the back caused by lying down for a long time. When the push rod 37 moves downward, the flap 21 will flip downward and reset under the action of gravity.

[0040] Extension rods 31 are fixedly connected to the left and right sides of the lower end surface of the middle bed board 19, and long connecting rods 32 parallel to the front bed board 22 are hinged to the lower ends of the extension rods 31. Foot pedals 23 are hinged to the front ends of the front bed board 22, and first connecting rods 33 hinged to the long connecting rods 32 are coaxially fixedly connected to the foot pedals 23.

[0041] like Figure 7 As shown, the first connecting rod 33 and the inner wall of the foot pedal 23 are fixedly connected with a rotating shaft, and the rotating shaft is rotatably connected to the inner wall of the front bed board 22, which is equivalent to the foot pedal 23 being hinged on the front bed board 22; the first connecting rod 33, the long connecting rod 32, the extension rod 31, and the front bed board 22 indirectly form a parallelogram mechanism, which can keep the foot pedal 23 always horizontal, that is, when the front bed board 22 flips downward, it can drive the corresponding foot pedal 23 to flip downward, and when the foot pedal 23 flips downward, under the limitation of the first connecting rod 33, the long connecting rod 32, and the extension rod 31, the foot pedal 23 can always keep the horizontal downward flipping, and after the foot pedal seat flips to the bottom, it can be stepped on by the elderly to support the feet of the elderly.

[0042] The outer surface of the long rotating shaft 13 is also fixedly connected with two active spur gears 38 , and the lower ends of the active spur gears 38 are respectively meshed with active spur racks 39 slidably connected to the bed body 1 , and the table 24 is installed on the two active spur racks 39 .

[0043] like Fig. 9 As shown, the active spur rack 39 can be slidably connected to the inner wall of the bed body 1 forward and backward. When the long rotating shaft 13 rotates, it can drive the two active spur gears 38 to rotate. When the active spur gears 38 rotate, they will engage with the active spur rack 39, thereby driving the active spur rack 39 and the table 24 to move forward or backward.

[0044] A connecting rod 40 is fixedly connected to the rear end surface of the two active spur racks 39, and an inner shaft 41 is rotatably connected to the inner wall of the connecting rod 40. A driven spur gear 42 is fixedly connected to the lower end of the outer surface of the inner shaft 41. A driven spur gear 43 fixed to the bed body 1 is meshed on the outer surface of the driven spur gear 42, and the table 24 is installed on the upper end of the inner shaft 41.

[0045] like Figure 9-11 As shown, the function of the connecting rod 40 is to limit the inner shaft 41, that is, when the connecting rod 40 moves forward and backward, it can drive the inner shaft 41 to move forward and backward, and the inner shaft 41 can also rotate; the installation and shape of the driven spur gear 42 and the driven spur rack 43 are as shown in FIG. Fig.11As shown, when the driven spur gear 42 moves forward or backward, it meshes with the driven spur rack 43, which causes the driven spur gear 42 and the inner shaft 41 to rotate; that is, when the active spur rack 39 and the connecting rod 40 move forward and backward, they can drive the corresponding inner shaft 41, the driven spur gear 42, the table 24, etc. to move forward or backward synchronously. When the table 24 moves forward or backward, the driven spur gear 42 meshes with the driven spur rack 43, which can drive the driven spur gear 42, the inner shaft 41, the table 24, etc. to rotate.

[0046] The outer surface of the inner shaft 41 is slidably connected to an outer shaft 44 , and a connecting ring 45 that can move up and down is rotatably connected to the outer surface of the outer shaft 44 . The table 24 is fixedly connected to the upper end surface of the outer shaft 44 .

[0047] like Fig.11 As shown, the inner shaft 41 and the outer shaft 44 are spline-connected, and the outer shaft 44 can slide up and down on the outer surface of the inner shaft 41, and when the inner shaft 41 rotates, it can drive the outer shaft 44 and the table 24 to rotate; the inner shaft 41 is rotationally connected to the outer shaft 44 through the connecting ring 45, and the connecting ring 45 does not affect the rotation of the outer shaft 44, and when the connecting ring 45 moves up and down, it can drive the outer shaft 44 and the table 24 to move up and down.

[0048] Two guide plates 47 are fixedly connected to the inner wall of the bed body 1 , and third sliding pins 46 are fixedly connected to the left and right ends of the outer surface of the connecting ring 45 . The guide plates 47 are respectively provided with inclined sliding grooves 48 matched with the third sliding pins 46 .

[0049] like Fig.11 As shown, through the engagement of the third sliding pin 46 and the inclined sliding groove 48, when the inner shaft 41, the outer shaft 44, the table 24, the connecting ring 45, and the third sliding pin 46 move backward, the engagement of the third sliding pin 46 and the inclined sliding groove 48 will drive the corresponding connecting ring 45 and the outer shaft 44 to move upward. Similarly, when the inner shaft 41, the third sliding pin 46, and the table 24 move forward, the table 24 will move downward under the engagement of the third sliding pin 46 and the inclined sliding groove 48; no further details will be given; therefore, when the long rotating shaft 13 rotates, the table 24 can move backward, upward, and rotate at the same time. The table 24 can rotate 90 degrees, and move backward and upward to be close to the elderly. At this time, food can be placed on the table 24 for the elderly to eat.

[0050] When the present invention is in use, when the rear bed board 20, the flap 21, the front bed board 22, the table 24 and the middle bed board 19 are in a horizontal state, they can serve as a monitoring bed for the user, that is, the elderly, to lie down and rest; when the elderly's upper body lies on the rear bed board 20 and the flap 21, the buttocks are placed on the middle bed board 19, and the lower limbs are placed on the corresponding front bed board 22, by providing a top rod 37 that can move up and down, the corresponding flap 21 can be driven to flip to one side, thereby assisting the elderly to turn over and prevent pressure sores on the back caused by lying down for a long time; when the user needs to defecate or eat, the rotatable long rotating shaft 13 can be used to drive the rear bed board 20 and the flap 21 to flip upward synchronously, assisting the elderly's upper body to flip and rise, and the front bed The plate 22 flips downward synchronously to assist the elderly to bend their legs downward, so that the elderly can assume a sitting position, thereby facilitating the elderly to eat or defecate; when the tray 18 moves downward, it can be out of contact with the middle bed plate 19, and by placing the toilet bucket on the tray 18, the excrement can be released into the toilet bucket when the elderly defecates; when the long rotating shaft 13 rotates, the table 24 will move backward, upward and rotate at the same time. The table 24 can rotate 90 degrees, and move backward and upward to be closer to the elderly.
