Hinge and foldable electronic apparatus therewith

A foldable electronic apparatus, comprising:

• a first casing;
• a second casing;
• and
• a hinge, the first casing and the second casing being pivotally connected by the hinge, the hinge comprising:
• a first connection member connected to the first casing;
• a second connection member connected to the second casing;
• a pivot, the first connection member and the second connection member being pivotally connected by the pivot so that the first casing and the second casing is capable of rotating relatively to be folded or unfolded;
• a first magnetic part connected onto the first connection member, the first magnetic part producing a radial magnetic field relative to the pivot;
• a second magnetic part moveably disposed relative to the first magnetic part and kinetically connected to the second connection member, a magnetic moment of the second magnetic part being opposite to a magnetic moment of the first magnetic part;
• an adjustment part kinetically connected to the second connection member and capable of driving the second magnetic part;
• and
• a guiding mechanism, kinetically connected to the first connection member and the adjustment part, for guiding the adjustment part to move in an axial direction of the pivot relative to the first magnetic part when the second connection member rotates relative to the first connection member;
• wherein when the second connection member rotates relative to the first connection member, the second connection member drives the second magnetic part by the adjustment part to rotate relative to the first magnetic part, so that a repulsive moment is induced between the first magnetic part and the second magnetic part for resisting the rotating of the second connection member relative to the first connection member, and the second connection member also drives the adjustment part to adjust a distance between the second magnetic part and the first magnetic part so as to vary the repulsive moment;
• wherein when the first casing and the second casing rotate relatively from a folded state to unfold to an unfolded, the repulsive moment increases overall.
