Abstract:
1. A hinge mechanism for a foldable electronic device having a first body and a second body, comprising: a hinge suitable to be fixed on the first body; a pivot part pivoted to the hinge and suitable to be connected to the second body; a friction part connected to the pivot part and selectively contacting the hinge, wherein when the pivot part rotates relative to the hinge to drive the first body to rotate from a close position to an open position relative to the second body, the friction part does not contact the hinge; and when the pivot part rotates relative to the hinge to drive the first body to rotate from the open position to the close position relative to the second body, the friction part contacts the hinge to limit a rotation of the pivot part on the hinge; and a rotation part telescoped on the hinge and contacting the friction part, wherein when the pivot part rotates relative to the hinge to drive the first body to rotate from the close position to the open position relative to the second body, the rotation part rotates with the hinge to drive the friction part to move far away from the hinge, so that the friction part does not contact the hinge; and when the pivot part rotates relative to the hinge to drive the first body to rotate from the open position to the close position relative to the second body, the rotation part drives the friction part to move towards the hinge, so that the friction part contacts the hinge and clamps the hinge tightly.
