There may be multiple supporting members 2, and the plurality of supporting members 2 are arranged at intervals along the length direction of the short bed rail 12.

In some embodiments, there may be multiple convex parts 21, multiple concave parts 22, and only one supporting member 2.

In other embodiments, the long bed rail may have a curved plate-like structure, as shown in FIG. 12A. In some embodiments, the long bed rail comprises a first side plate 401, a second side plate 402, and a bottom connecting plate 403. The bottom connecting plate 403 may be located between the first side plate 401 and the second side plate 402. In some embodiments, the first side plate 401 is shorter than the second side plate 402. The opening 10 may be formed between the first side plate 401 and the second side plate 402. In some embodiments, the edge 404 of the second side plate corresponding to the plug-in part 220 may be inserted into the plug-in part 220, referring to FIG. 12B. In some embodiments, the first side plate 401, the second side plate 402, and the bottom connecting plate 403 are integrally formed, and the first side plate 401 and the second side plate 402 can be perpendicular to the bottom connecting plate 403. The distance between the edge of the first side plate 401 and the bottom connecting plate 403 may be greater than the distance between the edge 404 of the second side plate 402 and the bottom connecting plate 403. This way can ensure that the supporting member 2 will not protrude from the edge of the first side plate 401. This makes the overall bed frame more beautiful. In some embodiments, when the support member 2 may be connected to the short bed rail, the structure of the short bed rail can also adopt the same bent plate structure as the above-mentioned long bed rail.

In some embodiments, the shape of the frame 1 may be not limited to a rectangular shape, and can also be selected based on the actual shape of the bed.

In some embodiments, the lower surface of the overlapping part 32 may be in contact with the upper surface of the long bed rail 11, and the lower surface of the convex part 21 overlaps the upper surface of the overlapping part 32.

In some embodiments, the connector 3 can be fixed in the opening of the frame before leaving the factory. When the consumer assembles, the support member 2 can be clamped into the insertion space 311. When the bed frame needs to be disassembled, it can be pulled out with a little force, and the connecting piece 3 can be used repeatedly.

In some embodiments, as shown in FIG. 20, the insertion part 31 may be provided with a limiting protrusion 312, and the limiting protrusion 312 can abut against the inner wall of the frame 1. When disassembling the support member 2, it may be necessary to pull it out with force. By providing the limiting protrusion 312, the connection member 3 can be effectively prevented from being separated from the frame 1. In some embodiments, as shown in FIG. 20, the connector 3 further comprises convex border 33, which are provided on the upper surfaces of the insertion part 31 and the overlapping part 32. This can not only increase the strength of the connector 3, but also cover the end edge of the supporting member 2, ensuring the overall aesthetics of the bed frame.

In some embodiments, the connector 3 may be made of plastic. This can avoid noise caused by rocking friction between the support member 2 and the frame 1.

In some embodiments, as shown in FIG. 21, the support member 2 comprises two convex parts 21 and a concave portion 22 located between two adjacent convex parts 21.

In some embodiments, the bed frame support structure may not have a connector 3. In this case, the support member 2 may not have a avoidance notches 212, so that the support member directly abut on the long bed rail 11 or the short bed rail 12. This may be suitable for the long bed rail with an L-shaped pipe, so that can avoid support member higher than the upper surface of the long bed rail. In some embodiments, this combination may be also used for a long bed rail as a rectangular pipe.
