1. A foldable electronic device, comprising:
a central body including a main body portion, a lifting plate, at least one first inner arc-shaped slider, and at least one second inner arc-shaped slider, wherein the first inner arc-shaped slider and the second inner arc-shaped slider are respectively formed in the main body portion by intervals, and the lifting plate is movably arranged in the main body portion and movable between a highest position and a lowest position;
a connecting module arranged in the central body and including a first shaft rod and a second shaft rod respectively inserted into the main body portion, wherein the first shaft rod extends along a first axis and has a first main gear, and the second shaft rod extends along a second axis and has a second main gear;
a first wing including a first support plate, at least one first inner arc-shaped groove, and at least one first outer arc-shaped groove, wherein the first support plate is movably arranged on one side of the lifting plate, and the first inner arc-shaped slider is slidably arranged in the first inner arc-shaped groove, so that the first wing is pivotable relative to the main body portion with a first inner virtual axis as a center;
a first transmission element sleeved on the first shaft rod and synchronously rotating with the first shaft rod;
a first panel body including a first bearing element capable of linear sliding relative to the first transmission element and having at least one first outer arc-shaped slider, wherein the first outer arc-shaped slider is slidably arranged in the first outer arc-shaped groove, thereby allowing the first bearing element to pivot relative to the first wing about a first outer virtual axis;
a second wing including a second support plate, at least one second inner arc-shaped groove, and at least one second outer arc-shaped groove, wherein the second support plate is movably arranged on the opposite side of the lifting plate, and the second inner arc-shaped slider is slidably arranged in the second inner arc-shaped groove, so that the second wing is pivotable relative to the main body portion with a second inner virtual axis as a center;
a second transmission element sleeved on the second shaft rod and synchronously rotating with the second shaft rod;
a second panel body including a second bearing element capable of linear sliding relative to the second transmission element and having at least one second outer arc-shaped slider, wherein the second outer arc-shaped slider is slidably arranged in the second outer arc-shaped groove, thereby allowing the second bearing element to pivot relative to the second wing about a second outer virtual axis;
a synchronous engaging module including a synchronous supporting block, a first auxiliary gear and a second auxiliary gear, wherein two ends of the synchronous supporting block are respectively sleeved on the first shaft rod and the second shaft rod, and the first and second auxiliary gears are reversely rotatably disposed on the synchronous supporting block and mesh with each other, and wherein the first auxiliary gear meshes with the first main gear in a reversely rotatable manner, and the second auxiliary gear meshes with the second main gear in a reversely rotatable manner, thereby enabling the first transmission element and second transmission element to synchronously and reversely rotate;
an elastic module including a pushing element slidably sleeved on the first shaft rod and the second shaft rod and movably engaged with the first transmission element and the second transmission element; and
a flexible screen disposed on the first panel body and the second panel body and including a bendable area;
wherein the first panel body and the second panel body are capable of switching between an unfolded state and a folded state, wherein when the first panel body and the second panel body are in the unfolded state, the flexible screen is flattened, the lifting plate is at the highest position, and the first support plate, the second support plate, and the lifting plate jointly support the bendable area, and wherein when the first panel body and the second panel body are in the folded state, the flexible screen is bent, the lifting plate is at the lowest position, and the first support plate, the second support plate, and the lifting plate jointly define a yielding space for accommodating the bendable area.
