Abstract
The application discloses a hinge mechanism and an electronic device, and belongs to the field of electronic devices. In the hinge mechanism, the first end of a swing arm is rotationally connected with a base, and the second end of the swing arm is slidingly connected with a shell connecting piece in a first direction. The second end of the swing arm is provided with a first cam piece, the first cam piece is slidingly connected with the swing arm along the rotation axis of the swing arm, and the shell connecting piece is provided with a second cam piece. A limiting assembly is arranged on the swing arm. When the hinge mechanism is in a folded state, the limiting assembly is located at a first position, and the limiting assembly is in limiting cooperation with the first cam piece in the rotation axis direction, so as to limit the relative movement of the first cam piece and the second cam piece in the first direction. When the hinge mechanism is in a non-folded state, the limiting assembly is located at a second position, and in the rotation axis direction, the limiting assembly avoids the first cam piece, so that the first cam piece and the second cam piece can relatively move in the first direction.
