Abstract: A rotating shaft mechanism includes a body, a first door plate, a second door plate, an intermediate door plate, a first connecting rod assembly, and a second connecting rod assembly. The first connecting rod assembly includes a first housing connecting rod, a first gear connecting rod, and a first secondary connecting rod. The rotating shaft mechanism further includes a first meshing transmission structure. The first housing connecting rod, the first gear connecting rod, the first secondary connecting rod, the first door plate, and the body form a crank-slider structure to drive the first door plate to rotate relative to the body. The first gear connecting rod drives the intermediate door plate to move relative to the body using the first meshing transmission structure.
