Triple-folding electric bed

Abstract

A triple-folding electric bed includes: a first bed body (11), a second bed body (12), and a third bed body (13). The first bed body (11), the second bed body (12), and the third bed body (13) are successively in detachable fixed connection or rotatable connection at junctions; when the electric bed is spread horizontally, the first bed body (11), the second bed body (12), and the third bed body (13) are on the same level; and when the electric bed is folded, the first bed body (11), the second bed body (12), and the third bed body (13) are folded in the thickness direction. The bed body of the triple-folding electric bed is divided into three separate parts and then fully folded to reduce the length of the electric bed, which thereby reduces the packaging size of the electric bed.
