Abstract: A portable electronic device comprises a cover member, a body member, and a power generating assembly. The cover member is slidably mounted to the body member. The power generating assembly includes a power generating device and a rack assembly. The power generating device includes a toothed gear and a stator. The toothed gear is rotatably clockwise or counter clockwise mounted to the stator. The stator is fixed to the body member. The rack assembly includes a fastening portion and a rack portion opposite to the fastening portion. The fastening portion is fixed to the cover member. The rack portion meshes with the toothed gear, thus the power generating device driving the rack assembly and the cover member to slide relative to the body member.

Abstract: A power supply device is provided as an accessory to a portable electronic device to supply electric power to the portable electronic device. The power supply device includes a shell and a battery. The shell defines a concave assembling portion for assembling the portable electronic device therein and is configured to provide a better viewing angle of the portable electronic device. The battery is assembled within the shell to supply electric power.

Abstract: A surface contact card latching assembly (100) is located in a portable electronic device (200). The latching assembly includes a receiving portion (11) and a latch portion (12). The receiving portion is configured for receiving a surface contact card (20). The receiving portion includes an aperture (113) formed at a first end thereof via which the surface contact card enters or exits, and a latching containing portion (114) formed at an opposite second end thereof. The latch portion is received in the latching containing portion. The latch portion is operable to move in the latching containing portion so as to drive the surface contact card to move out of the receiving portion through the aperture.

Abstract: A battery cover assembly for coupling to a housing of an electronic device, the battery cover assembly comprising: a cover (10) comprising an inner surface (106) and a button slot (101) defined therein; a movable member (20) comprising a main body (21), a button (211) formed on the main body and extending through the button slot, and a catch assembly extending from the main body; and a fixing plate (30) coupled to the cover, with the movable member being sandwiched between the fixing plate and the cover, the fixing plate defining at least one opening, the catch assembly of the movable member extending through the opening and being adapted for engageably securing the cover assembly to the housing (40). The battery cover assembly has a steady structure. The battery cover assembly is convenient to open and close.

Abstract: A portable electronic device comprises a housing and a chip card ejecting mechanism. The housing has a mounting portion defined therein. The ejecting mechanism includes a holder and a controlling module. The holder is slidably accommodated in the mounting portion of the housing. The controlling module includes a button and an ejecting element. The button releasably secures with the holder in the mounting portion. The ejecting element resistes against the holder to provide an elastic force for driving the holder slid. When the button is pressed, the holder is released and the ejecting element ejects the holder outwardly from the mounted portion of the housing.

Abstract: The invention discloses a card holding mechanism, which includes a housing, a retaining member mounting in one side of the housing and a sliding button slidably attached on another side of the housing. The housing defines a chamber therein, and the chamber is used for accommodating a chip card. The bottom of the chamber defines a through hole. The retaining member is used for receiving the chip card. The sliding button is fixed with the retaining button through the through hole. The chip card is accommodated in the chamber and is secured by the retaining member, when the sliding button is pushed, then the chip card with the retaining member are brought out from the chamber.

Abstract: A portable electronic device comprises a cover, a base and a sliding mechanism. The sliding mechanism includes a connecting rod mechanism and a controlling mechanism. The connecting rod mechanism is rotatably mounted between the base and the cover and is configured to rotate the cover relative to the base. The controlling mechanism is configured to control the rotation of the connecting rod mechanism.

Abstract: An exemplary chip card holder (100) used in a portable electronic device for holding a chip card (50) is provided. The chip card holder includes a housing member (10), a holding member (20), and a driving member (30). The holding member is fixed to the housing member for receiving and holding the chip card. The driving member is movable relative to the housing member and the holding member for moving the chip card from either of a released position and a holding position to the other of the holding position and released position.

Abstract: A electronic device (100) includes a removable chip card (40) for carrying information, comprise a housing (10) and a ejecting mechanism (30). The housing (10) defines a chamber (12) and a base (14) formed adjacent to the chamber. The chamber (12) is used for accommodating a battery (20) therein. The base (14) is used for receiving the chip card (40) therewith. The ejecting mechanism (30) is mounted in the housing (10) and includes a sliding member (32) and an elastic member (36). When the battery (20) is accommodated in the chamber (12), the chip card (40) is secured between the sliding member (32) and the battery (20). When the battery (20) is removed from the chamber (12), the elastic member (36) biases the sliding member (32) to eject the chip card (40) outwardly from the base (14).
