Abstract: A hinge mechanism includes two guide rod mechanisms that are respectively formed between a main shaft assembly in the hinge mechanism, a first support arm, a first guide rod arm, and a first connecting frame, and between the main shaft assembly in the hinge mechanism, a second support arm, a second guide rod arm, and a second connecting frame. A first support plate and a second support plate are respectively fastened to the first support arm and the second support arm. The first support arm and the first connecting frame are rotatably connected through a first arc-shaped sliding groove and a first arc-shaped arm that are in sliding fit. The second support arm and the second connecting frame are rotatably connected through a second arc-shaped sliding groove and a second arc-shaped arm that are in sliding fit.

Abstract: The support mechanism includes a first rotation module, a second rotation module, and a module support. The first rotation module includes a first door plate, a first support arm, a first housing support, and a first swing rod. The first door plate is used to support a flexible display. The first support arm is rotatably connected to the module support. The first door plate is rotatably connected to the first housing support. The first support arm is slidably connected to the first housing support. The first swing rod is slidably connected to the first door plate. A first end of the first swing rod is rotatably connected to the first housing support. A second end of the first swing rod can abut against the first support arm. When the electronic device falls, the housing support does not have a displacement or has a small displacement relative to the module support.
