1. A bed body structure, characterized in that the bed body structure includes a bearing mechanism, a turnover mechanism, a base and a flexible supporting layer;
the turnover mechanism is arranged between the bearing mechanism and the base, and the flexible supporting layer covers a top of the bearing mechanism; the bearing mechanism includes at least two supporting assemblies; in a flat-laid state, all the supporting assemblies are horizontally arrayed on a top of the base in sequence; and in an unfolded state, the turnover mechanism enables at least one of the supporting assemblies to be upwards turned over relative to the base;
wherein flexible coating structures have outside planes gradually inclining towards inner sides from top to bottom and inside planes gradually inclining towards inner sides from bottom to top; and flexible coating structures coat the supporting pieces at the edges of the bearing mechanism;
wherein the bearing mechanism includes a first supporting assembly, a second supporting assembly, a third supporting assembly, a fourth supporting assembly and a fifth supporting assembly; wherein the first supporting assembly and the second supporting assembly are in pivot connection at a junction, and the third supporting assembly, the fourth supporting assembly and the fifth supporting assembly are in pivot connection at junctions;
the first supporting assembly includes a first supporting piece, a second supporting piece, a third supporting piece and a fourth supporting piece, the second supporting assembly includes a fifth supporting piece, a sixth supporting piece, a seventh supporting piece and an eighth supporting piece, the third supporting assembly includes a ninth supporting piece, a tenth supporting piece, an eleventh supporting piece and a twelfth supporting piece, the fourth supporting assembly includes a thirteenth supporting piece, a fourteenth supporting piece, a fifteenth supporting piece and a sixteenth supporting piece, and the fifth supporting assembly includes a seventeenth supporting piece, an eighteenth supporting piece, a nineteenth supporting piece and a twentieth supporting piece;
the first supporting piece and the second supporting piece which are parallel to each other are perpendicular to the third supporting piece and the fourth supporting piece which are parallel to each other, the first supporting piece, the second supporting piece and the third supporting piece are fixedly connected, and the fourth supporting piece is in lap joint with tops of the first supporting piece and the second supporting piece;
the fifth supporting piece and the sixth supporting piece which are parallel to each other are perpendicular to the seventh supporting piece and the eighth supporting piece which are parallel to each other, and the seventh supporting piece and the eighth supporting piece are in lap joint with tops of the fifth supporting piece and the sixth supporting piece;
the ninth supporting piece and the tenth supporting piece which are parallel to each other are perpendicular to the eleventh supporting piece and the twelfth supporting piece which are parallel to each other, and the eleventh supporting piece and the twelfth supporting piece are in lap joint with tops of the ninth supporting piece and the tenth supporting piece;
the thirteenth supporting piece and the fourteenth supporting piece which are parallel to each other are perpendicular to the fifteenth supporting piece and the sixteenth supporting piece which are parallel to each other, and the fifteenth supporting piece and the sixteenth supporting piece are in lap joint with tops of the thirteenth supporting piece and the fourteenth supporting piece; and
the seventeenth supporting piece and the eighteenth supporting piece which are parallel to each other are perpendicular to the nineteenth supporting piece and the twentieth supporting piece which are parallel to each other, the seventeenth supporting piece, the eighteenth supporting piece and the twentieth supporting piece are fixedly connected, and the nineteenth supporting piece is in lap joint with tops of the seventeenth supporting piece and the eighteenth supporting piece.
