[0033] When the footrest 23 starts to reverse, the gap between the footrest 23 and the seat cushion 24 appears under the legs of the user. In order to prevent the leg muscles from being damaged by the gap, the elastic cushion 62 always shields the gap during the movement of the footrest 23.

[0034] A transfer machine 11 is also provided on one side of the nursing bed 1 .

[0035] The transfer machine 11 includes a chassis with wheels installed. Two armrests 111 are symmetrically arranged on the top of the chassis. Slots 112 are opened on the side of the two armrests 111 close to the nursing bed 1, and both ends of the slots 112 pass through the two sides of the corresponding armrests 111.

[0036] Insertion plates 25 are fixedly arranged on both sides of the seat cushion 24. The distance between the two insertion plates 25 is equal to the distance between the two armrests 111. The thickness of the insertion plate 25 is equal to the height of the inner hole of the corresponding slot 112.

[0037] The implementation principle of the above embodiment is: The user lies flat on the nursing bed 1. In order to transport the user to the transfer machine 11, the operator relies on the transfer machine 11 to move.

[0038] First, the operator controls one of the second motors 47 through the remote controller according to the lying position of the user, and the second motor 47 drives the first arc rod 43 to move, and the first arc rod 43 drives the corresponding flip plate 21 to rotate around the corresponding first fixed rod 44.

[0039] The flip plate 21 changes the lying position of the user, that is, moves the lying position of the user to the movable part.

[0040] The user's head is located at the backrest 22 , and the user's legs are located at the footrest 23 .

[0041] Next, the operator still uses the remote control to start the telescopic part 31, and the telescopic part 31 starts to move upward, driving the first fixed plate 32 to move upward. After the telescopic part 31 drives the entire movable part to move upward for a distance, the first rotating plate 34 contacts the bottom of the seat cushion 24. The telescopic part 31 stops working, and the first motor 33 starts working.

[0042] The telescopic portion 31 can fully support the entire movable portion and the user lying on the movable portion, and the seat cushion 24 can always maintain a horizontal position.

[0043] The first motor 33 drives the first rotating plate 34 to rotate. The friction between the first rotating plate 34 and the seat cushion 24 is large enough. After the first rotating plate 34 slowly drives the seat cushion 24 to rotate ninety degrees, the first motor 33 stops working.

[0044] Next, two third motors 56 start to work. First, the third motor 56 between the backrest 22 and the seat cushion 24 starts to work.

[0045] The third motor 56 drives the second gear 57 to rotate, and the second gear 57 drives the corresponding second rotating plate 53 to rotate. The second rotating plate 53 drives the corresponding backrest 22 to rotate 75 degrees and then stops working.

[0046] Next, the third motor 56 between the footrest 23 and the seat cushion 24 starts to work, and the third motor 56 drives the corresponding second rotating plate 53 to rotate, and the second rotating plate 53 drives the footrest 23 to rotate 75 degrees. It should be noted that the footrest 23 is completely located outside the bed frame 2 after rotating 90 degrees.

[0047] The footrest 23 has no contact with the bed frame 2 during the turning process.

[0048] The operator pushes the shifting machine 11 to the correct position, and as the shifting machine 11 part gradually approaches the bed frame 2. An entry hole is provided in the lower half of one side of the bed frame 2, and the chassis of the shifting machine 11 enters the entry hole, and the two plug plates 25 also enter the corresponding slots 112.

[0049] The footrest 23 is also located between the two armrests 111 , and the footrest 23 is located above the chassis.

[0050] Finally, the operator starts the first telescopic machine and the first motor 33 to return the first rotating plate 34 to the initial position and initial direction.

[0051] At this time, the user can already control the traveling direction and the motion state of the chassis through the operating lever on the armrest 111. The control system on the armrest 111 here belongs to the prior art.

[0052] The embodiments of this specific implementation method are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
