Abstract: A rotating shaft assembly and an electronic device, where the rotating shaft assembly includes a panel and a rotatable support mechanism. The rotatable support mechanism includes a swing arm, a fixed structure, a limit part, and a support structure. The support structure is provided with a mounting plane, and the panel is fastened to the mounting plane; a first limit portion is formed on the swing arm; and the limit part is connected to the support structure, and a second limit portion is formed on the limit part. When the screen is in a folded state, the limit part is separated from the swing arm. When the screen is in an unfolded state, the second limit portion of the limit part can abut against the first limit portion of the swing arm, thereby implementing mutual constraint between the swing arm and the support structure.

Abstract: Disclosed are a rotating shaft mechanism and a foldable mobile terminal. The rotating shaft mechanism provided in the embodiments of this application is mainly applied to a foldable mobile terminal, so as to implement unfolding and folding of two main body parts of the foldable mobile terminal. When the elastic support member is in a compressed state, at least some segments of the first part and the second part overlap in a floating direction, and the second part provides a compressed deformation space for a part or all of the first part. In this way, a height of the elastic support member in overall compression and deformation is reduced, and an ultra-thin design requirement of the foldable mobile terminal is met.

Abstract: A thermal extrusion method to fabricate large-dimension superhydrophobic cylinder pillar arrays with droplet pancake bouncing phenomenon. Preparing thermal extrusion mold: the through-hole arrays with 0.8˜1.25 mm diameter, 0.25 mm interval space and 0.6˜1.0 mm height are first obtained on metals, and are then polished, rinsed and dried. Thermal extrusion: polymer materials are first thermally extruded on the obtained mold and cooled to room temperature. Demold: excess polymer materials flowing from the through hole are cut off and then the polymer cylinder pillar arrays are lifted off from the mold. Superhydrophobic treatment: the whole polymer sample is treated using mixed liquid spray consisting of titanium oxide nanoparticles dispersed in fluoroalkylsilane ethanol solution, and the superhydrophobic cylinder pillar arrays are obtained.
