Abstract:
1. A portable computer, including: a base, with a front side and a rear side a front end and a read end thereof, having a first area defined at the front side and a second area defined at the rear side; a display module, including a connecting end, a free end relative to the connecting end, a display face, and a support plane relative to the display face; a support element, including a first fixed end and a second fixed end, the first fixed end being connected pivotally to a portion of the display module other than the display face so that the display module is able to rotate relative to the support element; a cam structure, including a first connecting portion and a second connecting portion, the first connecting portion being connected pivotally to the second fixed end so that the support element is able to rotate relative to the cam structure; the second connecting portion being connected pivotally to the rear end of the base or close to the rear end so that the cam structure is able to rotate relative to the base; accordingly, the support element is connected indirectly and pivotally to the base; and a torsion spring, disposed between the second connecting portion of the cam structure and the base, for providing elastic torque to assist the potential energy that the first connecting portion of the cam structure rotates normally towards the base; whereby, when the portable computer is in a closed state, the connecting end of the display module leans against the support element to resist the elastic torque of the torsion spring; when the portable computer the display module rotates relative to the base in an open state, the support element loses the support of the connecting end and the first connecting portion of the cam structure rotates towards a bottom the base by the elastic torque provided by the torsion spring.
