With reference to fig. 25, the working principle of the multifunctional bedside cabinet is as follows: after the folding accompanying and attending bed 10 is folded, the cushion moving frame 8 is positioned in the avoiding region 71 of the main moving frame 7, the tail plate 5 covers the outside of the avoiding region 71 and covers the lower part of the main moving frame 7, the backrest folding frame 9 is flatly placed on the cushion moving frame 8, and the front cushion 91 and the rear cushion 92 of the backrest folding frame 9 are stacked one on another; the folded folding bed 10 is accommodated in the accommodating cavity 16, and the bedside cabinet is in a state shown in the upper right corner of fig. 25; the tail board 5 is turned up along the direction of F1 alone, the bearing support piece 52 is enabled to support the tail board 5, the tail board 5 forms a flat stool, as shown in the direction of a1, in this state, the tail board 5 is lifted along the arrow F2, the lower end of the bearing support piece 52 is enabled to be away from the ground for a certain height, meanwhile, the bearing support piece 52 is pushed to turn along the arrow F3, and finally, the tail board 5 is lowered along the arrow F4, and the tail board 5 can be restored to the vertical closing state.

The folded bed 10 is pulled out from the storage chamber 16 in the arrow direction of T1 in the state shown in the upper right corner of fig. 25, and then the state a2 is formed; then, as in the state b, the backrest folding leg 9 is turned up in the direction of the arrow R and is tilted outward to form a chair, and if the tail board 5 is turned flat in the chair state, the chair is formed, which is not shown in the figure; in the state of the reclining chair, the cushion moving frame 8 is pulled outwards, so that the cushion moving frame 8 moves out of the main moving frame 7, the backrest folding frame 9 starts to be opened in the process that the cushion moving frame 8 moves outwards, and the folding accompanying bed 10 is completely unfolded to form a lying bed until the front cushion 91 and the rear cushion 92 are unfolded to be flat, which is shown as a state c in fig. 25.

When the folding accompanying bed 10 is unfolded, the connecting part of the front cushion 91 and the rear cushion 92 is lifted upwards along the arrow direction T5, and the cushion moving frame 8 is pushed towards the main moving frame 7 along the arrow direction T4 until the cushion moving frame 8 enters the avoiding area 71, and the backrest folding frame 9 is inclined outwards, so that a chair is formed; when the tail board 5 is in a flat state, the tail board 5 is lifted upwards along an arrow F, the bearing support piece 52 leaves the ground, then the bearing support piece 52 is pushed towards the cushion moving frame 8 along an arrow F3, the included angle between the bearing support piece 52 and the tail board 5 is smaller than 90 degrees, finally the tail board 5 and the bearing support piece 52 are put down, and the tail board 5 can be turned to be in a vertical state along an arrow F4 direction; the backrest folding frame 9 in the chair state is overturned on the cushion moving frame 8, at this time, the folding bed 10 is in the folding state, and can be pushed into the accommodating cavity 16 of the cabinet body 1 by referring to the state of fig. 22.

When the multifunctional bedside cabinet is taken out of the folding bed for accompanying and attending to 10, the following operations are required: when the folding accompanying bed 10 needs to be used in a storage state of the folding accompanying bed 10, the wake-up switch 21 is firstly touched, so that a remote communication function in the remote control circuit module 2 is wakened up, and the remote control circuit module 2 is communicated with a cloud end through a wireless network; the user adopts the smart mobile phone to scan remote procedure and gets into the two-dimensional code, and high in the clouds discerns behind the user identity instruction remote control circuit module 2 control electric control lock 22 and unblanks, and folding bed 10 of accompanying and attending to can shift out outside accomodating chamber 16 this moment, and then open the use.
