The movable mechanism B comprises a movable frame 6, at least one pair of sliding parts 4 arranged symmetrically on both sides of the movable frame 6, and the second cross bar 5 in the middle of the movable frame 6; the number of the movable rail 2 is corresponding to the sliding part 4 and they are engaged, the sliding part 4 can slide on the movable rail 2, and in the embodiment of the present invention, the movable rail 2 and the sliding members 4 are two pairs respectively, the movable rail 2 is a straight rail; the movable panel 601 is provided on the surface of the movable frame 6, and the back panel C and the movable panel 601 are hinged by the hinge 9. For the structural stability and the cost reduction, the number of the hinge 9 is generally 2-3, the bottom of the back panel C is connected to the first cross bar 3 through at least one connecting rod 8. The at least one connecting rod (8) is arranged in distance to each other and pivotally connected to the cross bar (3) so that at least one connecting rod (8) is arranged near an end range of the cross bar (3), thus bending stress applied thereon could be optimized. The driver 7 is provided between the first cross bar 3 and the second cross bar 5, preferably the driver is a motor; under the action of the driver 7, the slider 4 moves against the movable rail 2 to drive the movable mechanism B to move against the fixed mechanism A, and under the action of the hinge 9 and the connecting rod 8, the back panel C moves against the movable mechanism B and the fixed mechanism A, so that the function of the back panel C as a backrest or a bed board is realized.
