1. A hinge structure for connecting of an electronic device and a stand, comprising:
a housing disposed in the electronic device and having an opening atop, two half-housings, two lateral plates, an operation space formed by the half-housings and lateral plates, an arced portion disposed in the operation space, a cover covering a portion of the opening, wherein each of the half-housings comprises a rear protrusion and a lateral protrusion, and a guiding rail formed by the arced portion connected to a rear groove formed on the rear protrusion and two lateral grooves formed in the lateral protrusions; a lifting member disposed on the stand and comprising a planar portion covering the other portion of the opening which is not covered by the cover and an eccentric block comprising a connecting end connected to the planar portion, a U-shaped portion extending from the connecting end, an arced member extending from the U-shaped portion and a groove formed on the arced member, wherein the arced member is movably disposed in the guiding rail with a front end of the arced member movably disposed in the rear groove and a rear end of the arced member movably disposed in the lateral grooves, wherein an operation gap is formed between the cover and the planar portion; a guiding member disposed in the eccentric block and further disposed between the U-shaped portion and the groove and comprising an arced guiding groove and a through hole; a pin extending through the arced guiding groove; a positioning pin positioned in the lateral plates and movably extending through the through hole; and an elastic torsion member disposed on the positioning pin. |
