  • Patent number: 9201466
    Abstract: A portable computer includes a base, a display module, a support element and a cam structure. The base comprises a first area and a second area. The display module includes a connecting end and a display face. The support element includes a first end connected pivotally to a portion of the display module other than the display face and a second end connected pivotally to the rear end of the base. Two ends of the cam structure are connected pivotally to the base and the support element. Accordingly, the support element is connected indirectly and pivotally to the base. When the display module is slid and rotated relative to the base to change a notebook state or a tablet state, the support element does not interfere the movement of the display module and keep the flatness of the whole appearance of the portable computer.

  • Patent number: 9158341
    Abstract: A portable computer includes a base, a keyboard module, a pushing assembly, a display module, and a sliding assembly. The base includes a front end and a rear end. The keyboard module includes two keyboard portions; each keyboard portion is moveably combined with the base by at least one moving structure. The pushing assembly includes two pushing elements combined moveably with the base. The display module includes a connecting end and a support portion. The sliding assembly includes a slide corresponding element disposed in the base and a sliding element pivoted on the connecting end and moved along the slide corresponding element. When the connecting end moves towards the front end with the slide element, the pushing assembly pushes and moves the moving structures by the slide element, and the two keyboard portions are separated; then the connecting end is moved through the keyboard module with the slide element.

  • Patent number: 8976519
    Abstract: A portable computer includes a base, a display module, a support element and a sliding assembly. The base defines a first area and a second area between a front end and a rear end thereof, The display module includes a connecting end having a connecting element. Two ends of the support element are pivoted respectively to the rear end of the base and the display module. The sliding assembly includes a slide guiding structure disposed in the second area and a sliding element moving along the slide guiding structure. The sliding element includes an engaging portion for detachably engaging with the connecting element. When the connecting end of the display module moves from the second area to the first area with the sliding element, the connecting end is moved to stride across the first area by detaching the connecting element from the engaging portion.

  • Patent number: 8922984
    Abstract: A portable computer includes a base, a display module, and a support element. The base includes a first area, a second area, and a sliding assembly disposed at a substantially central position of the second area. The sliding assembly includes a sliding element and a guiding structure, and the sliding element can move along the guiding structure to slide at least in the second area. The display module includes a connecting end combined with the sliding element and a support plane. The support element includes a first area pivotally connected to the support plane and a second end pivotally connected to a rear end of the base. When the display module is opened, the display module further rotates around the first fixed end and moves the connecting end simultaneously. Then, the display module is supported by the support element to keep a suitable tilted angle.
