Abstract: A sliding mechanism for a cellular phone includes a low-profile base provided on one surface with a central recess and a pair of parallel elongated sliding slots located at two lateral sides of the recess; a supporting bracket slidably connected to the surface of the base with the recess; and a plurality of flat elastic members each having a first and a second telescopic element respectively pivotally connected to the base and the supporting bracket. The base is enclosed in a plastic material through insert molding to have a slim body that enables a reduced overall thickness of the cellular phone. And, the flat elastic members allow the supporting bracket to smoothly slide relative to the base in a balanced manner.

Abstract: The present invention relates to a foldable keyboard comprising a left base plate, a right base plate, and a link shaft. Each of the base plates has a side pivotally connecting to the link shaft, enabling the base plates to expand and fold. The invention is characterized in that a first keypad secured on the left base plate; a second keypad glidingly mounted on the right base plate, and at least a linkage mechanism with a first pivot joint, a second pivot joint, and a third pivot joint; whereby the first, second, and third pivot joints are pivotally connected to the left base plate, the link shaft, and the second keypad respectively, allowing the linkage mechanism to pull the second keypad close to the first keypad when the left and right base plates are expanded horizontally; and when the left and right base plates are folded, the linkage mechanism pushes the second keypad away from the first keypad.

Abstract: A camera positioning seat includes a connecting device, an hook, and a position device. The connecting device has a connecting piece. One surface of the connecting piece has an embedding piece, a rear surface of the camera is installed with a buckling groove with respect to a position of the embedding piece. An elastic hook is installed at one lateral side of another surface of the connecting piece. The position device has a fixing box, and a sticky object is installed at one surface of the fixing box. Thereby, when the camera is to be fixed to the display device, the embedding piece of the connecting piece is embedded into the buckling groove at the rear side of the camera, and then the hook at another surface of the connecting device is hooked to the fixing box. Afterwards, by the sticky object of the fixing box is fixed to the display device and thus, the camera is fixed to the display device. The structure of the positioning seat has a simple structure and can be assembled and detached convenient.
