Ultra-thin four-fold bed

Abstract

This invention belongs to the field of folding bed technology and discloses an ultra-thin four-folding bed, including a folding bed body, a first bed frame, and a second bed frame. The folding bed body consists of a first hip bed board, a second hip bed board, a back bed board, a head bed board, a leg bed board, and a footboard. A first drive mechanism is installed on the first bed frame, and a second drive mechanism is installed on the second bed frame. After the folding bed body is folded, the first bed frame, the second bed frame, the first drive mechanism, and the second drive mechanism are all folded between the first hip bed board and the second hip bed board. This invention adopts a four-folding design, which significantly reduces the volume after folding compared to the existing two-layer folding structure, occupies less storage space, is suitable for small apartment living environments and temporary storage scenarios, and is also more convenient to move. The first bed frame and the second bed frame are folded in an interlocking manner, and the drive mechanism and the bed frame are stored between the two hip bed boards after folding, making reasonable use of the internal space and further compressing the folding volume.
