1. A foldable electronic device, comprising:
a first body, having a display surface and a back surface;
a second body;
a first hinge module, having a first shaft and a second shaft, wherein the first shaft is pivotally connected to the first body, the second shaft is pivotally connected to the second body, and the second shaft has a virtual axis;
a second hinge module, disposed on the second body and having a rotating shaft, wherein the rotating shaft is disposed corresponding to the virtual axis;
a driving sheet, located between the first shaft and the second shaft, wherein the driving sheet is located between the first hinge module and the second hinge module; and
a one-way bearing, rotatably disposed around the rotating shaft and having a bearing stop portion corresponding to the driving sheet;
wherein when the first body is flipped relative to the second body, the driving sheet rotates to a first position along a first rotation direction and contacts the bearing stop portion, and the one-way bearing and the rotating shaft are driven to rotate simultaneously relative to the second body, so that the back surface faces the second body,
wherein the second hinge module further comprises:
a fixing member, connected to the second body and disposed around the rotating shaft;
a plurality of torque members, disposed around the rotating shaft; and
a locking attachment, locked to the rotating shaft to sandwich the torque members between the fixing member and the locking attachment.
