The gyro sensor 33 senses that the nursing bed has moved to a sloped position, and then controls the adjustment device 50 to drive the bed board 20 to move, so that the bed board 20 moves to a horizontal position, so that the patient always lies flat and avoids the discomfort caused by the tilt. In the adjustment process, the base 10 will not be affected and can maintain normal movement. Therefore, when moving on the slope, it can ensure that the patient lies normally without affecting the normal movement, which is more convenient to use.

Both ends of the base 10 are fixedly installed with fixed blocks 11; the bed board 20 also includes: a fixed plate 21, one side of which is fixedly connected to the bed board 20; a guide plate 22, which is fixedly connected to the other side of the fixed plate 21; the stabilizing structure 40 includes: a fixed sleeve 41, which is fixedly connected to the side of the fixed seat 31 close to the bed board 20; a movable plate 42, which is movably connected to the fixed sleeve 41 and extends from the inside of the fixed sleeve 41 to the outside of the fixed sleeve 41; a plurality of stabilizing springs 43, which are fixedly installed in the inside of the fixed sleeve 41 and extend to the inside of the movable plate 42, and the total restoring force of the stabilizing springs 43 is much smaller than the gravity of the bed board 20; a rotating shaft 44, which is fixedly connected to the guide plate 22, passes through the movable plate 42, and is movably connected to the movable plate 42; the first angle sensor 60 is fixedly connected to the movable plate 42, and its detection end is connected to the rotating shaft 44.

During the rotation process, the bed board 20 rotates around the rotating shaft 44 , and the rotation of the bed board 20 drives the guide plate 22 to rotate, thereby driving the rotating shaft 44 to rotate. The first angle sensor 60 can obtain the rotation angle of the bed board 20 through the rotation angle of the rotating shaft 44 .

A pair of adjustment devices 50 includes: a pair of bottom plates 51, which are fixedly connected to the base 10 and are located on both sides of the fixed seat 31; a plurality of electric push rods 52, which are respectively located on both sides of the fixed seat 31, and are fixedly connected to the fixed seat 31 and fixedly connected to the bottom plate 51; a pair of sliders 53, which are fixedly connected to the output ends of the electric push rods 52; a plurality of guide rods 54, whose two ends are respectively fixedly connected to the fixed block 11 and the bottom plate 51, and pass through the sliders 53; a plurality of support rods 55, whose two ends are respectively hinged to the sliders 53 and the bed board 20; and a plurality of reinforcing rods 56, which are fixedly connected to the support rods 55.

When the electric push rods 52 on both sides move in the same direction, the support rods 55 on both sides can be driven to shrink on one side and prop up on the other side, thereby causing the angle of the bed board 20 to change. When the electric push rods 52 on both sides move in opposite directions, the support rods 55 on both sides can be driven to shrink or prop up synchronously, thereby making the bed board 20 higher or lower. The operation is simple, and it is convenient for medical staff to adjust the angle and height of the nursing bed. At the same time, the adjustment used is only for the bed board 20, and the base 10 will not be affected, thereby ensuring the stability of the base 10, and then ensuring the stability of movement.

The angle detection device 70 includes: a pair of clamping plates 71, which are fixedly installed on one side of the bed board 20 close to the base 10; a movable rod 72, one end of which is rotatably installed between the pair of clamping plates 71 and the other end is away from the clamping plate 71; a counterweight block 73, which is spherical and fixedly connected to one end of the movable rod 72 away from the clamping plate 71; a pair of soft cushions 74, which are fixedly connected to the bed board 20 and located on both sides of the clamping plate 71; a second angle sensor 75, which is fixedly connected to the clamping plate 71 and is used to detect the rotation angle of the movable rod 72.

When the nursing bed is stationary, under the action of gravity, the counterweight block 73 will pull the movable rod 72 so that the movable rod 72 is in a vertical state. Therefore, when the movable rod 72 and the bed board 20 are in a vertical state, it can be judged that the bed board 20 is horizontal, otherwise it is judged that it is not horizontal.

A method for using a transfer nursing bed comprises the following steps:
