1. A foldable electronic device, comprising:
a plurality of foldable units, each of the foldable units comprising:
a central base including a body portion, a lifting plate, a first arc-shaped groove and a second arc-shaped groove, the first arc-shaped groove and the second arc-shaped groove being formed on the body portion and opposite to each other, and the lifting plate being movably disposed on the body portion and movable between a highest position and a lowest position;
a hinge module including a first shaft and a second shaft, wherein the first shaft and the second shaft respectively penetrate through the body portion and capable of rotating synchronously and reversely;
a first wing including a first arc-shaped part slidably disposed in the first arc-shaped groove so that the first wing is able to pivot relative to the body portion;
a first driving element being sleeved on the first shaft and synchronously rotating with the first shaft;
a first panel body including a first bearing element, the first bearing element being pivoted to the first wing and linearly slidable relative to the first driving element;
a second wing including a second arc-shaped part slidably disposed in the second arc-shaped groove so that the second wing is able to pivot relative to the body portion;
a second driving element being sleeved on the second shaft and synchronously rotating with the second shaft;
a second panel body including a second bearing element, the second bearing element being pivoted to the second wing and linearly slidable relative to the second driving element; and
an elastic module including a push element, a first elastic element, and a second elastic element, the push element being sleeved on the first shaft and the second shaft and movably engaged with the first driving element and the second driving element, the first elastic element being sleeved on the first shaft and abutting against the push element, and the second elastic element being sleeved on the second shaft and abutting against the push element; and
a flexible screen being disposed on the first panel body, the first wing, the second panel body and the second wing of each of the foldable units, and comprising a bendable area;
wherein the first panel body and the second panel body are convertible between an unfolded status and a folded status, wherein when the first panel body and the second panel body are in the unfolded status, the flexible screen is flattened, the lifting plate is at the highest position so that the first wing, the second wing and the lifting plate collectively support the bendable area; and wherein when the first panel body and the second panel body are in the folded status, the flexible screen is bent at the bendable area, the lifting plate is at the lowest position, and the first wing, the second wing and the lifting plate collectively define an accommodating space for accommodating the bendable area.
