  • 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: 8699224
    Abstract: The present disclosure relates to a computer peripheral device. The computer peripheral device includes a housing whereon an opening is formed, and a fixing module installed inside the opening in a reversible manner. The fixing module includes a base installed inside the opening, a locking head passing through the locking plate and fixed on the base at one end. The locking head includes a latching part for inserting into a slot on a casing of a portable computer when the base turns to a first position relative to the housing so that the latching part protrudes outside the housing. When the locking plate is pressed down so as to separate the latching part from the locking plate and the locking head rotates relative to the locking plate, the latching part cannot separate from the slot. The fixing module further includes a resilient component for pushing the locking plate.

  • Patent number: 8531837
    Abstract: A pad mechanism includes a step fixing structure having a plurality of step platforms. A height difference is formed between the two step platforms. A first engaging portion is formed on each step platform. The pad mechanism further includes a pad component having a pad body, a sleeve and a constraining portion. A second engaging portion is formed on the pad body for selectively engaging with the corresponding first engaging portion so as to adjust a height of the pad body protruding from the step fixing structure. The pad mechanism further includes a resilient component sheathing with the sleeve for driving the sleeve, and a constraining component installed on a side of the resilient component and connected to the constraining portion so as to prevent the resilient component from separating from the sleeve.
