Hinge mechanism and electronic device

An electronic device, comprising a display, screen support components, and a hinge mechanism, wherein the hinge mechanism comprises a base, first rotating components, second rotating components, a first connecting component, a second connecting component, a floating support component, and elastic reset members;

• there are a plurality of first rotating components and a plurality of second rotating components, the plurality of the first rotating components are disposed on the base, and the plurality of the second rotating components are rotatably connected to the plurality of the first rotating components in a one-to-one correspondence;
• both the first connecting component and the second connecting component are fixedly connected to the screen support components of the electronic device, at least one of the plurality of the second rotating components is fixedly connected to the first connecting component, and at least another one of the plurality of the second rotating components is fixedly connected to the second connecting component;
• the floating support component is disposed on a side of the base that faces a screen support side of the base, and the floating support component is movably connected to the base along an arrangement direction of the floating support component and the base;
• there are a plurality of elastic reset members, the elastic reset members are connected between the floating support component and the base, the plurality of the elastic reset members comprise a first reset member and a second reset member, the first reset member is on one side of a midpoint of the base in a direction of a rotation axis of the first rotating components, the second reset member is on another side of the midpoint of the base, and an angle between a connection line between the first reset member and the second reset member and the rotation axis is an acute angle;
• and
• the hinge mechanism has a first state and a second state, and in a case that the hinge mechanism is in the first state, the first connecting component is on one side of the base, the second connecting component is on another side of the base, at least one of the plurality of the second rotating components supports the floating support component, the elastic reset members are in a compressed state to squeeze the floating support component and the second rotating components, and a distance between an outer wall of the base that faces away from the rotation axis of the first rotating components and the floating support component is a first distance;
• and
• in a case that the hinge mechanism is in the second state, both the first connecting component and the second connecting component are on a side of the base that faces the rotation axis of the first rotating components, the second rotating components avoid the floating support component, a distance between the outer wall of the base and the floating support component is a second distance, and the second distance is less than the first distance;
• wherein both the first connecting component and the second connecting component are connected to the screen support components, and the display is supported on the floating support component of the hinge mechanism and the screen support components.
