The host includes a housing having a bottom surface, a raising mechanism disposed in the housing, and a pad connected to the raising mechanism, and adjacent to the bottom surface. The hinge mechanism is connected to the host and includes a first shaft connected to the raising mechanism. The display is affixed to the rotation element. When the display is rotated about the host, the first shaft drives the raising mechanism to change the distance between the top of the pad and the bottom surface. ## Claims ### Claim 1 A laptop computer, comprising: a host comprising: a housing having a bottom surface; a raising mechanism disposed in the housing; and a footpad connected to the raising mechanism, and adjacent to the bottom surface, wherein the footpad has a top end far from the bottom surface; a hinge mechanism connected to the host, and comprising: a first shaft connected to the raising mechanism; and a display connected to the hinge mechanism, and being rotatable relative to the host via the hinge mechanism, wherein when the display is rotated relative to the host, the first shaft drives the raising mechanism to change a distance between the top end and the bottom surface of the footpad. ### Claim 2 (depends on 1) The laptop computer as claimed in claim 1, wherein while the display is moving from a cover position to an open position, a distance between the top end and the bottom surface increases gradually, wherein while the display is moving from the open position to the cover position, the distance between the top end and the bottom surface decreases gradually. ### Claim 3 (depends on 1) The laptop computer as claimed in claim 1, wherein the raising mechanism is a mechanical raising mechanism. ### Claim 4 (depends on 1) The laptop computer as claimed in claim 1, wherein the raising mechanism comprises: a gear connected to the first shaft; and a rack engaged with the gear, and connected to the footpad. ### Claim 5 (depends on 1) The laptop computer as claimed in claim 1, wherein the raising mechanism comprises: a gear assembly connected to the first shaft; and a cam connected to the gear assembly, and in contact with the footpad, wherein when the display is rotated relative to the host, the gear assembly drives the cam to rotate. ### Claim 6 (depends on 5) The laptop computer as claimed in claim 5, wherein when the display is in a cover position, there is a first distance between the top end and the bottom surface, and when the display is in an open position, the cam abuts the footpad, and there is a second distance between the top end and the bottom surface, wherein the second distance is greater than the first distance. ### Claim 7 (depends on 1) The laptop computer as claimed in claim 1, wherein the host further comprises a base disposed in the housing, and having a curved groove, and the hinge mechanism further comprises a rotation element comprising a curved portion located in the curved groove, wherein when the display is rotated relative to the host, the curved portion is rotated relative to the curved groove along a curved path. ### Claim 8 (depends on 7) The laptop computer as claimed in claim 7, wherein the curved path is a circular path, and the curved groove and the curved portion are C-shaped. ### Claim 9 (depends on 7) The laptop computer as claimed in claim 7, wherein the hinge mechanism further comprises: a torque assembly connected to the rotation element, and configured to apply a torque between the host and the display; and a fixed element connected to the torque assembly, and affixed to the housing. ### Claim 10 (depends on 9) The laptop computer as claimed in claim 9, wherein the torque assembly comprises the first shaft pivoting on the fixed element, wherein the torque assembly further comprises: a connection element connected to the first shaft; and a second shaft connected to the connection element and the rotation element, and extending parallel to the first shaft. ### Claim 11 (depends on 10) The laptop computer as claimed in claim 10, wherein the torque assembly further comprises a plurality of torque elements disposed on the first shaft, and the torque elements are configured to apply a torque between the first shaft and the fixed element. ### Claim 12 (depends on 1) The laptop computer as claimed in claim 1, further comprising: a first curved cover connected to the rotation element; a second curved cover connected to the rotation element, wherein a gap is formed between the second curved cover and the first curved cover; and a transmission wire connected to the host and the display, and located in the gap.
