The second bed side board 42 is rotatably arranged with the foot bed assembly 2. The foot bed assembly 2 can be close to or away from the bed screen 1 and be in a folded state or an unfolded state. When the foot bed assembly 2 is in the unfolded state, the two bed side assemblies 4, the bed screen 1 and the foot bed assembly 2 can be surrounded to form a frame structure, and the connecting plate 32 is locked relative to the fixed seat 31. When the foot bed assembly 2 is in the folded state, the foot bed assembly 2, the second bed side board 42 and the first bed side board 41 are stacked in sequence, and the connecting plate 32 is unlocked relative to the fixed seat 31.

[0045] Specifically, the bed screen 1 stands upright against the background wall of the bedroom, the bed screen 1 and the foot assembly 2 are respectively arranged at the two ends of the two bed side assemblies 4, the first bed side board 41 and the second bed side board 42 are rotatably arranged, the first bed side board 41 and the bed screen 1 are rotatably matched through the self-locking assembly 3, the second bed side board 42 and the foot assembly 2 are rotatably arranged, the self-locking assembly 3 includes a fixing seat 31 and a connecting plate 32, the fixing seat 31 is installed on the bed screen 1, the connecting plate 32 is arranged on the fixing seat 31 and can rotate relative to the fixing seat 31 and has an unlocking position and a locking position, when it is in the unlocking position, the connecting plate 32 and the fixing seat 31 can rotate relatively freely, so that the bed frame can be freely unfolded or folded without being constrained, and when it is in the locking position, the connecting plate 32 is fixed relative to the fixing seat 31 by a fixing method such as a snap connection or a plug connection, so as to prevent the bed frame in the unfolded state from folding. When the bed frame needs to be folded, the fixing seat 31 and the connecting plate 32 are unlocked, that is, the connecting plate 32 can rotate freely relative to the fixing seat 31, and the foot assembly 2 is pushed, and the foot assembly 2 gradually approaches the bed screen 1, and the foot assembly 2, the second bed side board 42, the first bed side board 41 and the bed screen 1 are stacked in sequence. At this time, the bed frame is in a folded state, which saves the placement space of the bed frame, is convenient for handling and transportation, and can clean the bottom of the bed. When the bed frame needs to be unfolded, the foot assembly 2 is pulled, and the foot assembly 2 gradually moves away from the bed screen 1, and the first bed side board 41 and the second bed side board 42 are unfolded, and are surrounded by the foot assembly 2 and the bed screen 1 to form a frame structure, and then, the relative position of the fixing seat 31 and the connecting plate 32 is locked, that is, the connecting plate 32 is locked relative to the fixing seat 31, so that the bed side assembly 4 is always arranged vertically with the bed screen 1 and the foot assembly 2.
