Abstract: A chip card ejecting mechanism includes a base body, a push member, a rotating member and an elastic member resisting between the base body and the rotating member. The base body includes a guiding member defining a hole and having a number of guiding rails. Each guiding rail includes a resisting surface and a guiding surface. The push member includes a push rod extending through the hole and a number of active gears. Each active gear defines an active cooperative surface. The rotating member includes a number of the passive gears. Each passive gear includes a passive cooperative surface. When the push member is pressed toward the rotating member by a transient external force, the rotating member compresses the elastic member until the active cooperative surface arrives at the guiding surface, the elastic member releases and drives the passive cooperative gears to slide along the first sliding slot.

Abstract: A surface contact card holder includes a main body defining an entrance and a recess communicating with the entrance, a tray for receiving a surface contact card, and a door attached to an end of the tray and releasably received in the entrance. The tray is slidably received in the main body through the entrance. The door includes an operation board comprising elastic material and a fastening board attached to the operation board. The fastening board is movably connected to the tray. The operation board is positioned adjacent to the recess.

Abstract: A latching assembly is used in an electronic device. The electronic device includes a first housing and a second housing. The latching assembly includes at least a pair of latching elements and at least a pair of locking elements corresponding to the latching elements. Each latching element includes a hook located in the first housing, and a catch member defined in the second housing. Each locking element includes a movable member received in the first housing. Each hook clasps one of catch members to engage the first housing and the second housing. Then the movable member moves to the second housing to resist against the hook, thereby limiting the movement of the hook relative to the catch member. An electronic device using the latching assembly is also described.

Abstract: A protective case includes a main body having a recess and a flange in the recess, a strengthening plate received in the recess. The strengthening plate includes a latching block. The latching block is latched with the flange to latch the strengthening plate in the recess. When the case is used to protect an electronic device, the strengthening plate shield the electronic device from damaging.

Abstract: An accessory strap fixing structure is positioned on a portable electronic device to assemble an accessory strap. The accessory strap fixing structure includes an assembling space and a rotary element. The assembling space defined in the portable electronic device. The rotary element is rotatably assembled within the assembling space. The rotary element forms a projection for attaching an end of the accessory strap to allow the accessory strap to pass through the assembling space. The invention also discloses a portable electronic device having the accessory strap fixing structure.

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: A battery cover assembly for a portable electronic device includes a battery cover, a base body, and a latching member. The battery cover defines a groove. The base body defines two cutouts. The latching member is received in the groove. The latching member includes a main section and two elastic arms. The main section includes two clasps received in the cutouts. The arms are fixed to the groove of the battery cover to allow the battery cover to releasably latch to the base body.

Abstract: A battery cover latching assembly comprises a body member, a battery cover, and two elastic members. One end of the battery cover is rotatably mounted to the body member, the other end of the battery cover is releasably latched to the body member. The two elastic members are sandwiched between the battery cover and the body member, used to prop up the battery cover.
