Foldable device and an electronic device

Abstract

A foldable device is provided. The foldable device includes a foldable assembly, a connecting hinge disposed on a side of the foldable assembly, a drop limiting mechanism, and a positioning member. The connecting hinge is slidable relative to the foldable assembly. The positioning member is connected to the foldable assembly. The drop limiting mechanism includes a connecting member connected with the foldable assembly and a first connecting rod connecting the connecting hinge and the connecting member. The positioning member includes a first limiting portion. When unfolding the foldable device, the connecting member moves relative to the connecting hinge to drive the first connecting rod to move toward the first limiting portion relative to the connecting hinge, until the first connecting rod abuts against or is adjacent to the first limiting portion to prevent the connecting hinge from further moving toward the foldable assembly.
