Abstract: A foldable keyboard assembly includes a foldable structure and a rotary foldable keyboard. The foldable structure includes a first foldable member, a third foldable member, and a second foldable member foldably disposed therebetween. A portable electronic device is detachably disposed on the third foldable member. The rotary foldable keyboard includes a support board, a first keyboard, and a second keyboard. The support board is disposed on the first foldable member. The first keyboard and the second keyboard are movably disposed on the support board and pivotally connected to each other. When the first keyboard and the second keyboard are folded relatively, they are contained in the foldable structure. When the first keyboard and the second keyboard are expanded relatively, the second foldable member can bend relative to the third foldable member for supporting the portable electronic device to abut against a side of the rotary foldable keyboard.

Abstract: A portable keyboard includes a base, a casing pivotally connected to the base, and a foldable keyboard. The foldable keyboard is disposed on the base and includes a first keyboard module, a second keyboard module and a pivot. The first keyboard module is pivotally connected to the second keyboard module by the pivot, such that the first keyboard module and the second keyboard module can be folded or expanded with respect to each other over the base. When the first and second keyboard modules are folded with respect to each other over the base, the foldable keyboard can be accommodated in the casing. When the casing rotates with respect to the base such that an angle is formed therebetween, the first and second keyboard modules can be expanded with respect to each other over the base.

Abstract: A portable keyboard includes a base, a holder, a support member, a foldable keyboard and a linking member. One end of the support member is pivotally connected to the base and the other end of the support member is pivotally connected to the holder. The foldable keyboard is disposed on the base and includes a first keyboard module, a second keyboard module and a pivot. The first keyboard module is pivotally connected to the second keyboard module by the pivot, such that the first and second keyboard modules can be folded or expanded with respect to each other over the base. One end of the linking member is connected to the pivot and the other end of the linking member is pivotally connected to the holder, such that the holder and the foldable keyboard can move together with each other.
