1. An electronic device, comprising:
a shaft assembly and housings arranged oppositely;
wherein the shaft assembly comprises:
a first shaft case, the housings being at least partially disposed at two opposite sides of the first shaft case;
first rotating members at least partially disposed at the two opposite sides of the first shaft case, each of the first rotating members having one end rotatably connected with the first shaft case and another end movably connected with the housings; and
rotating units at least partially disposed at the two opposite sides of the first shaft case, each of the rotating units comprising a second rotating member and a movable plate, the second rotating member having one end rotatably connected with the first shaft case and another end connected with the movable plate, and the movable plate having one end rotatably connected to the housings, wherein different portions of a flexible screen of the electronic device are respectively supported by the movable plate and the housings, and a surface of the movable plate supporting the flexible screen and a surface of the housings supporting the flexible screen are coplanar; and
a rotation axis around which the first rotating member is rotatable relative to the first shaft case is parallel to a rotation axis around which the second rotating member is rotatable relative to the first shaft case;
wherein the movable plate has a first rotating portion at one end thereof, the housing has a second rotating portion, the first rotating portion and the second rotating portion cooperate with each other to allow the movable plate to be rotatably connected with the housing at one end of the movable plate;
wherein the first shaft case comprises a baffle plate, two first sidewalls arranged oppositely and two second sidewalls arranged oppositely, the baffle plate, the first sidewall, and the second sidewalls arranged oppositely define a third receiving space, wherein the electronic assembly further comprises a damping mechanism at least partially received in the third receiving space;
wherein the damping mechanism comprises an elastic member, a first limiting portion, a second limiting portion, and a third limiting portion, the third limiting portion has one end connected with the elastic member and the other end abutted against the first limiting portion and the second limiting portion, wherein the first limiting portion has a first protruding portion protruded from part of a first flat surface of the first limiting portion, the first protruding portion has a first inclined surface connected with the first flat surface, the third limiting portion has a second protruding portion protruded from part of a second flat surface of the third limiting portion, the second protruding portion has a second inclined surface connected with the second flat surface, when the electronic assembly is in unfolded state, the first flat surface abuts against the second flat surface, and the first inclined surface abuts against the second inclined surface, when the electronic assembly rotates, the first inclined surface abuts against the second inclined surface.
