Referring to fig. 1, the rotating mechanism 40 and the elevating mechanism 30 are located at or below the middle position of the upper bed 20, and at this time, the rotating mechanism 40 uses a space that is free inside the elevating mechanism 30.

Referring to fig. 1, the arm rests 22 are provided on the left and right sides of the mattress 60 in the bracket 50, the arm rests 22 themselves have a width (perpendicular to the paper surface), and soft materials such as sponge and the like are provided on the upper sides of the mattress 60 and the arm rests 22 for buffering the impact. The upper side of the armrest 22 is higher than the upper side of the mattress 60, which also acts as a fence.

Referring to fig. 1, the mattress 60 includes three bed boards hinged in sequence, the hinge axis of the bed board is perpendicular to the paper surface, the bed board on the left is used as a backup plate 61, the bed board in the middle is used as a seat 62, the bed board on the right is used as a leg 63, the hinge between the bed board used as the backup plate 61 and the bed board used as the seat 62 is arranged on the upper side of the bracket 50, the hinge between the bed board used as the seat 62 and the bed board used as the leg 63 is arranged in a suspension manner, every two telescopic push rods 70 form a Y shape and then are arranged between the backup plate 61 and the bracket 50, and every two telescopic push rods 70 are connected end to end and then are arranged between the seat 62 and.

Taking the bending state in fig. 1 as an illustration, the user sits at the hinge between the back plate 61 and the seat plate 62 (the design is such that the hinge can bear the large gravity and transmit the gravity to the bracket 50), and the length of the seat plate 62 is suitable to ensure that the knee bending part of the user just can be placed at the hinge between the seat plate 62 and the leg plate 63, so that the use experience is optimal. In the present embodiment, the upper bed body 20 is provided with a horizontal fourth bed plate as a foot plate 64 at a position close to one side of the leg plate 63, and when the three bed plates are horizontal, the bed plate as the leg plate 63 is aligned with the fourth bed plate. The length of the leg plate 63 also needs to be set properly to ensure that the heel of the user can extend out of the lower right of the leg plate 63 in the bent state of fig. 1.

In fig. 1, it can be seen that the left side of the mattress 60 has two telescopic rods 70, one of the telescopic rods 70 having a lower end hinged to the bracket 50 and an upper end hinged to the back plate 61, and the other telescopic rod 70 having an upper end hinged to the back plate 61 and a lower end hinged to the telescopic rod 70. The right side of the mattress 60 is provided with two telescopic push rods 70, the two telescopic push rods 70 are respectively positioned below the seat plate 62 and the leg plate 63, the hinged position of the two telescopic push rods 70 is positioned below the seat plate 62 and the leg plate 63, and the left end and the right end of the two telescopic push rods 70 are respectively hinged with the right ends of the bracket 50 and the leg plate 63. From a balance point of view, the telescopic pushrods 70 are suggested to be evenly positioned on the left and right sides of the mattress 60 or below the midline of the mattress 60.

The operation of the nursing bed is described below.

Initially, the lower bed body 10 and the upper bed body 20 are in the closest position, the mattress 60 is unfolded flat, and the user lies flat on the mattress 60.

When the user wants to get up, the switch (which can be a solid key switch or a switch on a remote controller) is triggered. At this time, the lifting mechanism 30 pushes the upper bed body 20 to rise to a proper height (the height of each person is different, the leg length is different, and the proper height for sitting and standing is also different); meanwhile, the mattress 60 is folded, the backup plate 61 and the seat plate 62 are upwards warped and slowly formed into a V shape, the leg plate 63 is downwards inclined, and the seat plate 62 and the leg plate 63 are slowly formed into an inverted V shape; while the mattress 60 is deformed, the bracket 50 is slowly rotated by 90 ° around the axis line of the rotating mechanism until the length direction of the mattress 60 is along the width direction of the upper bed 20 (the direction perpendicular to the paper surface). The backrest 61 is further inclined to 70-90 deg., the seat plate 62 gradually returns to horizontal and the leg plate 63 gradually returns to vertical, and the above change requires that the joint between the seat plate 62 and the leg plate 63 can be shifted out of the upper bed 20, and the mattress 60 is similar to a chair, and the user is in a sitting posture. The user's hands may then hold the armrests 22 clear of the mattress 60.

When the user needs to get out of the bed from a new position, the mattress 60 needs to be in a sitting position. After the user sits down, the seat plate 62 tilts up and slowly lifts up the user together with the backup plate 61, and the leg plate 63 and the seat plate 62 form an inverted V shape, so that the knees of the user are naturally bent. The mattress 60 rotates 90 degrees around the axial lead of the rotating mechanism until the length direction of the mattress 60 is along the length direction of the upper bed body 20, and meanwhile, the mattress 60 slowly restores to a flat state; in the above process, the upper bed body 20 may be lowered to a suitable height.

The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
