1. A portable computer comprising:
a base comprising, between a front end and a rear end, a base surface including a first area disposed at a front side of the base and a second area disposed at a rear side of the base, wherein the base surface has a slit; a display module comprising a connecting end, a display face, and a support plane opposite to the display face; at least one supporting element, with each supporting element comprising a first fixed end and a second fixed end, with the first fixed end pivotally connected to a portion of the display module other than the display face, with the display module rotatable relative to the at least one supporting element; with the second fixed end pivotally connected to the rear end of the base or a proximity of the rear end of the base with the at least one supporting element rotatable relative to the base; and at least one sliding assembly, with each sliding assembly comprising a sliding block and a slide rail, with the slide rail disposed below the base surface and at least in the second area of the base, with the slide rail including upper and lower surfaces parallel to and spaced from the base surface, with the upper surface intermediate the base surface and the lower surface, with the upper surface divided into first and second portions on opposite sides of the slit; with the sliding block connected with the connecting end of the display module and sliding along the slide rail, wherein the sliding block comprises a sliding portion and at least one auxiliary sliding structure, wherein the sliding portion is disposed within the slide rail and includes an outer surface abutting with the upper and lower surfaces of the slide rail, wherein the at least one auxiliary sliding structure is at least a sheet-like structure with a flat surface disposed at the outer surface and abutting at least one of the upper and lower surfaces of the slide rail to reduce friction between the sliding block and the slide rail; wherein when the display module is opened and rotated to an angle relative to the base via the second fixed end of the at least one supporting element, the display module further rotates around the first fixed end with the first fixed end serving as a pivot point and simultaneously drives the connecting end to move from the second area towards the first area to a suitable position along with the sliding block; and then the display module is supported by the at least one supporting element to keep a suitable tilted angle. |
