1. A foldable electronic device, comprising:
a central body comprising a stationary shell, an accommodating space, a first shaft and a second shaft, wherein the stationary shell defines the accommodating space, the first shaft and the second shaft are disposed in the accommodating space, the first shaft extends along a first central axis, and the second shaft extends along a second central axis;
a linkage unit comprising a first driving shaft and a second driving shaft, wherein the first driving shaft is pivotally connected to the stationary shell on a first rotating axis and has a first sliding groove and a first arc groove, and the second driving shaft is pivotally connected to the fixed shell on a second rotating axis and has a second sliding groove and a second arc groove;
a first operating mechanism comprising:
a first wing rod pivotally connecting to the stationary shell on a first pivoting axis and pivotally connecting to the first driving shaft, and having a first supporting surface and a first protruding end being slidably disposed in the first arc groove;
a first lifting plate being fixed to the first wing rod and having a first lifting surface substantially contacting with the first supporting surface in parallel; and
a first connecting rod being fixed to the first shaft and pivotally connecting to the first driving shaft, and having a first rod end being slidably disposed in the first sliding groove;
a second operating mechanism comprising:
a second wing rod pivotally connecting to the stationary shell on a second pivoting axis and pivotally connecting to the second driving shaft, and having a second supporting surface and a second protruding end being slidably disposed in the second arc groove;
a second lifting plate being fixed to the second wing rod and having a second lifting surface substantially contacting with the second supporting surface in parallel; and
a second connecting rod being fixed to the second shaft and pivotally connecting to the second driving shaft, and having a second rod end being slidably disposed in the second sliding groove;
a first panel body being disposed on one side of the stationary shell and linking up with the first driving shaft;
a second panel body being disposed on another side of the stationary shell and linking up with the second driving shaft; and
a flexible screen being disposed on the first panel body and second panel body and having a flexible section;
wherein the first panel body and the second panel body are transformed between an unfolded status and a folded status; and
wherein when the first panel body and the second panel body are in the unfolded status, the flexible screen is flattened, and the first wing rod, the first lifting plate, the second wing rod, the second lifting plate and the stationary shell collectively support the flexible section; and when the first panel body and the second panel body are in the folded status, the flexible screen is bent, and the first wing rod, the first lifting plate, the second wing rod, the second lifting plate and the stationary shell collectively define a yielding space for accommodating the flexible section.
