Hinge Mechanism and Electronic Device

A hinge mechanism, comprising:

• an inner hinge;
• an outer hinge detachably connected to the inner hinge;
• and
• a rotating assembly disposed between the inner hinge and the outer hinge, wherein the rotating assembly comprises:
• a first swing arm;
• a second swing arm;
• and
• a linkage structure, wherein the linkage structure comprises:
• a first translation member slidably connected to the inner hinge and clamped to the first swing arm;
• a second translation member slidably connected to the inner hinge and clamped to the second swing arm;
• and
• a rotating member connected to the first translation member and the second translation member and rotatably connected to the inner hinge,
• wherein a rotation axis of the rotating member is parallel to a first direction from the inner hinge to the outer hinge,
• wherein when in a process in which the hinge mechanism switches from a flattened state to a folded state, the first swing arm and the second swing arm are configured to rotate relative to each other along a rotation axis of the hinge mechanism to drive the first translation member and the second translation member to slide reversely along directions parallel to a second direction,
• wherein when the first translation member and the second translation member slide, the rotating member is configured to rotate,
• wherein the second direction intersects both a third direction of the rotation axis and the first direction, and
• wherein the first direction is perpendicular to the third direction of the rotation axis.

An electronic device, comprising:

• a first plate;
• a first housing comprising a first surface, wherein the first housing is detachably connected to the first plate;
• a second plate;
• a second housing comprising a second surface, wherein the second housing is detachably connected to the second plate;
• and
• a hinge mechanism comprising:
• an inner hinge;
• an outer hinge detachably connected to the inner hinge;
• a rotating assembly disposed between the inner hinge and the outer hinge, wherein the rotating assembly comprises:
• a first swing arm;
• a second swing arm;
• and
• a linkage structure comprising:
• a first translation member slidably connected to the inner hinge and clamped to the first swing arm;
• a second translation member slidably connected to the inner hinge and clamped to the second swing arm;
• and
• a rotating member connected to the first translation member and the second translation member and rotatably connected to the inner hinge, wherein a rotation axis of the rotating member is parallel to a first direction, and the first direction is a direction from the inner hinge to the outer hinge;
• and
• a third surface on a side that is of the inner hinge and that is disposed away from the rotating assembly,
• wherein when in a process in which the hinge mechanism switches from a flattened state to a folded state, the first swing arm and the second swing arm are configured to rotate relative to each other along a rotation axis of the hinge mechanism to drive the first translation member and the second translation member to slide reversely along directions parallel to a second direction,
• wherein when the first translation member and the second translation member slide, the rotating member is configured to rotate,
• wherein the second direction intersects both a third direction of the rotation axis and the first direction, and
• wherein the first direction is perpendicular to the third direction of the rotation axis;
• and
• a flexible display that continuously covers the first surface, the second surface, and the third surface, and is fastened to the first surface and the second surface.
