Abstract

A rotating shaft mechanism, a support apparatus, and a foldable screen device, and relates to the field of foldable screen device technologies. The rotating shaft mechanism includes a rotating shaft base, a shaft cover, a first swing arm, and a first drive mechanism. The shaft cover is located on a back side of the rotating shaft base, the first swing arm is rotatably connected to the rotating shaft base, and the first swing arm can rotate between an unfolded position and a folded position relative to the rotating shaft base. The first drive mechanism is connected between the first swing arm and the shaft cover, and when rotating from the unfolded position to the folded position, the first swing arm drives, by using the first drive mechanism, the shaft cover to move toward the rotating shaft base.

Dependent claims

A rotating shaft mechanism, applied to a foldable screen device, comprising:

a rotating shaft base, wherein the rotating shaft base is configured to support a part of a foldable screen;
a shaft cover, wherein the shaft cover is located on a side that is of the rotating shaft base and that is away from the foldable screen;
and
a first drive mechanism, comprising:
a second swing arm, capable of rotating relative to the rotating shaft base and having an unfolded location and a folded location;
an actuating member, wherein the actuating member is fastened relative to the second swing arm and comprises an eccentric protrusion part;
and
a lift slider, provided with a second sliding groove, wherein the eccentric protrusion part is disposed through the second sliding groove, and is capable of sliding along the second sliding groove, wherein:
when the second swing arm rotates from the unfolded location to the folded location, the actuating member rotates with the second swing arm, and actuates the second sliding groove by using the eccentric protrusion part to drive the lift slider to move, so that a distance between the shaft cover and the rotating shaft base becomes smaller;
and
when the second swing arm rotates from the folded location to the unfolded location, the actuating member rotates with the second swing arm, and actuates the second sliding groove by using the eccentric protrusion part to drive the lift slider to move, so that the distance between the shaft cover and the rotating shaft base becomes larger.
