The sliding rod 21 is hinged with the bed frame 20, and the sliding rod 21 adopts a curved structure, that is, the middle part has an obtuse angle, and the obtuse angle is 120° to 170°. When the driving part 23 pushes the bed board to turn over, the flip rod 22 drives the sliding rod 21 to rotate with the hinge point of the sliding rod 21 and the bed frame 20 as the rotation axis, the second roller 212 rolls on the bottom surface of the corresponding bed board, and pushes the corresponding bed board relative to the bed frame 20 Turn up, when the pushed bed board is turned to 20° to 30° relative to the bed frame 20, the first roller 211 contacts the bottom surface of the bed board and rolls on the bottom surface.

In addition, each turning device and the bed board are not in a connection relationship. Once an object prevents the bed board from falling, the turning device and the bed board change from a contact state to a non-contact state to prevent pinching.

Preferably, a reinforcing plate 221 is provided at the included angle between the sliding rod 21 and the turning rod 22 . The connection strength between the sliding rod 21 and the turning rod 22 is enhanced, and the strength of the turning device is improved.

Preferably, FIG. 4 is a schematic diagram of the force arm of the flipping mechanism in the first embodiment of the present invention. As shown in FIG. 4 , the horizontal direction of the flipping device in the flat state is adjusted according to the following formulas (1) and (2). The lengths and positions of the gravity arm, the first resistance arm and the second resistance arm, so as to reduce the length of the power arm in the vertical direction of each flipping device in the flat state:

F1=(G×L3)÷L1 (1);

L2>(F1×L4)÷F (2);

Wherein, the first resistance arm is above the second resistance arm.

The resistance F1 is the force perpendicular to the bed frame 20 from the contact point between the second roller 212 and the slide rail, the load G is the gravity perpendicular to the midpoint of the bed board that the second roller 212 contacts, and the gravitational arm L3 is the contact point of the bed with the second roller 212. The straight line distance from the midpoint to the rotation axis of the bed board, the resistance arm L1 is the straight line distance from the contact point between the second roller 212 and the bed board to the rotation axis of the bed board, and the power arm L2 is from the hinge point of the sliding rod 21 and the bed frame 20 to The straight-line distance of the extension line of the thrust F.

The length of the power arm L2 is proportional to the thickness of the turning device, that is, the shorter the length of the power arm L2, the thinner the turning device is, which in turn affects the thickness of the smart bed. For example, increase the length of the first resistance arm, decrease the length of the gravity arm to reduce the resistance, and in the case of reducing the resistance, reduce the length of the second resistance arm to further reduce the length of the power arm, etc. When F<3000N, G>1285N, that is, when the intelligent bed bears the weight of the human body, through the force analysis, simulate changing the position of the force arm, calculate the change of the force, find the best force arm, and optimize the structure of the force arm of the intelligent bed , reduce the thickness of the smart bed, make it thinner, effectively control the volume of the smart bed, and reduce transportation costs.

When the driving part 23 does not work, each flipping device loses its support, and the flipping device will exceed the bottom surface of the bed frame 20 in the vertical space. The limit rod 201 provides effective support for each flipping device and restricts the flipping device to the bottom surface of the bed frame 20 . Between it and the bottom surface of the corresponding bed board, instead of the driving part 23, it bears the gravity, so that the service life of the driving part 23 is prolonged. When the bed board is in a flat state without being turned over, the second roller 212 contacts the bottom surface of the corresponding bed board and cooperates with the limit rod 201 to provide effective support for the bed board, reducing unnecessary travel. Faster feedback on user commands. Most importantly, the limiting rod 201 also limits the lowest position of each flipping device by limiting the flipping rod 22 , further reducing the thickness of the smart bed, reducing the size of the smart bed, and making it easier to transport and thinner.

Further, the bed frame 20 includes: a front frame 202 and a rear frame 203, and the front frame 202 and the rear frame 203 are hinged.
