Abstract: A SIM card holder includes a base (10) and a catching mechanism (20). The base defines a receiving groove (114) and a slot (110). The receiving groove is configured for receiving the SIM card therein. The base comprises a protrusion (108). The protrusion and the slot are arranged at two opposite sides of the receiving groove. The catching mechanism comprises a main board (201) having a bending piece (202) and a bending hem (204) at two opposite ends thereof The bending piece is detachably engaged with the base, and the bending hem is constantly retained in the slot of the base. The main board comprises an elastic slice resisting the protrusion of the base when the bending piece being engaged with the base. The catching mechanism is movable relative to the base and rotatable about the end of the bending hem when the slice disengages from the protrusion.

Abstract: A portable electronic device (101) includes a battery cover (200), a latch (200) and a housing (300). The battery cover has a resisting portion (114). One end of the latch has a limiting portion (207), another end of the latch having an engaging portion (208). The housing has a positioning portion. The latch moveably engages with the housing, and the resisting portion of the cover locks with the engaging portion for releasably locking the battery cover. The limiting portion engages with the positioning portion so as to limit the cover to open relative to the housing. This release provides a user with convenient and easy to use disassembly mechanism for the device.

Abstract: A battery cover latching assembly (50) for a portable electronic device (100) includes a housing (20), a first cover (10) configured for attaching to a first side of the housing, and a second cover (30) configured for attaching to a second side of the housing. The battery cover latching assembly includes a locking portion (131), a latch (342), and a button (40). The locking portion is formed on the first cover. The latch is formed on the second cover, the latch is engageable with the locking portion so as to lock the first cover and second cover with each other. The button is configured so as to be retained by the housing, the button is operable to deform the latch so as to unlock the first cover and the second cover.

Abstract: A SIM card holder (200) includes a receiving groove (11) defined in a body (10) and a latch module (12). The body defines a receiving groove configured for receiving a SIM card (20) therein and has a bottom surface at the receiving groove. The latch module includes a holding piece (101) extending from the body and located above the receiving groove, and an elastic element is located adjacent to one end of the receiving groove. The holding piece is separated from the bottom surface along a first axis perpendicular to the bottom surface at a distance essentially equal to a thickness of the SIM card, the elastic element is configured for latching the SIM card in the receiving groove along a second axis parallel to the bottom surface and is configured for being downwardly deformable to release the SIM card.

Abstract: A chip card retaining mechanism for retaining a chip card (30) mounted in an electronic device is provided. The electronic device includes a housing (10) having a battery compartment (12) defined therein. The chip card retaining mechanism includes a receiving cavity (14) formed on the housing for receiving the chip card therein, and a locking member (20). The receiving cavity has an opening facing the battery compartment of the electronic device. The locking member is movably received in the receiving cavity with a first end thereof extending out of the opening. The locking member includes a resisting portion. The resisting portion is configured for abutting a first end of the chip card. The locking member configured for locking the chip card in the receiving cavity.

Abstract: A hinge assembly (10) for joining a cover section (012) to a body section (014) of a foldable electronic device (01) includes: a button (1); a locking element (2); a main shaft (4); a driving spring (3); a cam (5) including a latching cam surface (54) on one end thereof, and two reverse rotating grooves (56) on another end thereof; a barrel (6) including two latching posts (62) engaging in the grooves; an end shaft (8); and a torsion spring (7) including two end portions attached to the barrel and the end shaft. The button, the locking element and the driving spring are located around one end of the main shaft, and the cam and the barrel are located around another end of the main shaft. When the button is pushed, the hinge assembly fully opens the cover section from body section. This provides a user with convenient one-handed operation.

Abstract: A housing mechanism includes a housing, a defending element, and a magnetic unit. The housing has a cavity, and an opening defined in a sidewall of the housing. The opening communicates with the cavity. The defending element is rotatably attached to an inner side of the sidewall adjacent the opening. The magnetic unit is fixed adjacent to the opening and configured for causing the defending element to return to cover the opening by a magnetic force produced by the magnetic unit.
