  • Patent number: 8218313
    Abstract: An electronic device housing includes a housing body, a movable foot pad mechanism disposed in housing body, a ventilation grille, a fan, and a fan switch connected electrically to the fan. The movable foot pad mechanism includes a foot pad pivoted to a bottom wall of the housing body. The foot pad is turnable pivotally to prop up the housing body so as to increase a space below a bottom of housing body. When the foot pad is being turned pivotally to prop up the housing body, the ventilation grille is moved simultaneously so as to make the space inside the housing body open to the ambient environment, and the fan is activated for heat dissipation, thereby increasing the heat dissipation efficiency of the electronic device housing.

  • Patent number: 8208247
    Abstract: An unloading mechanism includes a base and a pushing component installed on the base for pushing an electronic component out of a computer device. The unloading mechanism further includes a latch for latching the pushing component. When the electronic component pushes a first end of the pushing component in a first direction, a second end of the pushing component drives the latch to move in a second direction. The unloading mechanism further includes a first resilient component connected between the latch and the base for driving the latch to move in a direction opposite to the second direction, and a second resilient component connected between the pushing component and the base for driving the pushing component to move in a direction opposite to the first direction.

  • Publication number: 20110255245
    Abstract: A power supply device includes a transformer and a heat-dissipating mechanism. The heat-dissipating mechanism includes a heat-dissipating fan unit and an activating unit. The heat-dissipating fan unit is connected pivotally to the transformer, and is pivotable relative to the transformer to lie on a top surface of the transformer. An inclination angle of the heat-dissipating fan unit relative to the top surface of the transformer is adjustable. The activating unit includes a control switch for controlling activation of the heat-dissipating fan unit.

  • Publication number: 20110222720
    Abstract: A speaker module includes a casing whereon an opening is formed. The casing includes a blocking structure disposed on a side of the opening. The speaker module further includes a first speaker device, which includes a first housing, a first speaker unit disposed inside the first housing, and an engaging component connected to an end of the first housing for engaging with the blocking structure when the first housing is pulled out of the casing through the opening and for rotating relative to the blocking structure so as to adjust an angle of the first speaker unit. The speaker module further includes a second speaker device connected to the first speaker device and capable of passing through the opening, which includes a second housing connected to the first housing in a slidable manner relative to the first housing, and a second speaker unit disposed inside the second housing.

  • Publication number: 20110141335
    Abstract: A lens module of an imaging device includes a lens-barrel plate, a shutter plate and at least one elastic device. The lens-barrel plate includes at least one guide post, which is vertically arranged on the surface of the lens-barrel plate. The shutter plate includes at least one groove, which facilitates movement of the guide post in the groove. Each elastic device corresponds to an associated guide post and groove. Accordingly, the elastic device is compressed when external force is exerted on the lens-barrel plate and the shutter plate, and the elastic device recovers to separate the shutter plate from the lens-barrel plate when the external force is removed.

  • Publication number: 20110094766
    Abstract: An electronic device including a housing, a cover plate, and a button is provided. The cover plate is separably disposed on the housing and corresponds to an opening on the housing. A groove is formed on an edge of the cover plate. The button pivotally connects to an edge of the housing which encompasses the opening. The button can rotate on a housing plate of the housing and corresponds to the position of the groove. The button is behind the edge of the housing while the button is in a release position; a portion of the button extends out and into the groove of the cover plate while the button rotates to a lock position.
