When the folding mechanism is folded, it can drive the first side edge group 11 and the second side edge group 12 to fold and collapse close to each other, so that the baby bed is in a collapsed state, see Figure 8 , which is convenient for storage and reduces the storage space; on the contrary, when the folding mechanism is unfolded, it can drive the first side group 11 and the second side group 12 to move away from each other, so that the baby bed is in an unfolded state, see Figure 6 , to meet the sleeping or gaming needs of users.

[0040] refer to Figure 1-5In the present embodiment, the first side group 11 and the second side group 12 both include an outer frame assembly 13, a side panel assembly 14 and a locking assembly 15, wherein the outer frame assembly 13 includes two side beams 131 and an upper cross beam 132, the upper ends of the two side beams 131 are connected and fixed by the upper cross beam 132, and it is particularly noted that the upper cross beam 132 and the upper ends of the two side beams 131 can be integrally formed or detachably connected, the upper cross beam 132 and the two side beams 131 together enclose an inverted "U"-shaped door hole 130, which respectively connects the inside and the outside of the crib for the baby to crawl and play through, so as to increase the baby's range of activities and make the playability higher, thereby meeting the baby's crawling and playing needs, and the upper cross beam 132 on the outer frame assembly 13 can be used for children to hang and play. The side panel assembly 14 is disposed at the door opening 130 and its lower end is rotatably connected to the lower ends of the two side beams 131, and is used to open or close the door opening 130, so that the side panel assembly 14 can be switched between a closed state (i.e., a vertical state or a crib state) and an open state (i.e., a horizontal state or a play bed state). The side panel assembly 14 is locked or unlocked with the upper cross beam 132 and / or the two side beams 131 through the locking assembly 15. Thus, when the side panel assembly 14 is unlocked from the upper crossbeam 132 and / or the two side beams 131 by the locking assembly 15, the side panel assembly 14 can be flipped downward to open the door hole so that the side panel assembly 14 can be placed flat on the ground. At this time, children can enter and exit freely, the baby has a larger range of activities, and the playability is higher, and the child can use the upper crossbeam 132 for hanging and playing; conversely, when the side panel assembly 14 is unlocked from the upper crossbeam 132 and / or the two side beams 131 by the locking assembly 15, when the side panel assembly 14 can be flipped upward to close the door hole, the baby can only move or sleep within the range of the crib.

[0041] In particular, in other embodiments, the outer frame assembly 13 and the side panel assembly 14 in the first side group 11 or the second side group 12 can be integrally formed, so that the connection structure between the frame assembly 13 and the side panel assembly 14 in one of the side groups can be omitted. At this time, only one of the side groups can be opened, while the other side group cannot be opened, which not only meets the needs of infants crawling and playing, but also helps to improve assembly efficiency and reduce manufacturing costs.
