Abstract:
1. A portable computer with a hidden keyboard, comprising: a main system having a display device disposed on a surface of the main system, and a concave portion disposed on another surface of the main system opposite to the display device, and a pair of troughs each having one through opening located on two ends of the main system respectively; a pair of positioning components respectively disposed at the two troughs; and a support board having an open slot disposed concavely inward at an end for movably storing a keyboard, and a pair of lugs respectively disposed at two sides of the support board and pivotally connected to the main system to form a pivotal connection with the support board, wherein a surface of each lug facing each of the positioning components has a pivot disposed thereon, an end of each pivot facing away from each of the lugs passes through each of the positioning components and the through openings of the troughs, two first tracks are disposed on two corresponding sides of the open slot respectively, each of the first tracks includes a first arc-shaped trough disposed on a location of the first track adjacent to the opening of the open slot and a second arc-shaped trough disposed on a location of the first track distal to the first arc-shaped trough and the opening of the open slot, the keyboard includes two second tracks disposed on both sides thereof for engaging with the first tracks respectively, and each of the second tracks comprises a pair of arc-shaped blocks disposed on each of the second tracks for engaging with the first arc-shaped troughs or the second arc-shaped troughs; and wherein the end of the support board with the open slot is thereby pivotally connected to the main system, the main system can be pivotally turned to press against a surface of the support board so as to allow the main system to be integrated with the support board, or pivotally turned away from the support board so as to support the main system on a flat surface; each positioning component presses against the main system and the support board when the support board is turned away from the main system and placed on the flat surface, the pair of arc-shaped blocks engages with each of the second arc-shaped troughs when the keyboard is completely stored into the open slot and, when the keyboard is completely moved out of the open slot, the pair of arc-shaped blocks engages with each of the first arc-shaped troughs.
