Deployable　structures　are　widely　utilized　in　various　fields　due　to　their　ability　to　switch　between　a　deployed　working　state　and　a　folded　storage　state.　This　paper　presents　a　new　method　for　achieving　plate　forms　in　deployable　structures,　allowing　the　formation　of　closed　surfaces　suitable　for　covering　purposes.　Initially,　a　novel　one-degree-of-freedom　(one-DOF)　deployable　network　is　proposed,　employing　Bennett　linkages　and　Bennett-based　6R　linkages.　Subsequently,　the　shape　of　the　links　in　the　network　is　modified　to　obtain　a　plate　form　consisting　of　equilateral　triangular　panels.　The　paper　also　conducts　kinematic　analysis,　motion　property　examination,　and　bifurcation　condition　discussion　to　demonstrate　the　folding　properties　of　the　proposed　mechanism.　Additionally,　a　modified　scheme　is　proposed　to　enable　the　structure　to　form　a　closed　surface,　and　physical　prototypes　are　used　to　validate　all　the　results.　Overall,　the　proposed　method　presents　new　possibilities　for　developing　practical　and　versatile　deployable　structures　with　broader　applications.
