A battery cover latching mechanism (300) for latching a battery cover (20) on a housing (10) of a portable electronic device. The battery cover has a fixing portion (204) defining a hollow (206) therein. The latching mechanism includes a button (30), a locking member (40) and an elastic member (60). The button (30) has an inclined surface (308). The locking member has a claw (408) engaged with the hollow and a slanted surface (414) that resists the inclined surface. The button is mounted in the housing and is movable along a first direction. When the button moves along the first direction, the locking member is driven to slide along a second direction perpendicular to the first direction, so as to move the claw from a first position where the claw engages in the hollow to a second position where the claw releases from the hollow.

What is claimed is: 1. A battery cover latching mechanism for use in a portable electronic device, the portable electronic device having a housing and a battery cover, the housing defining a receiving hole and a groove, the battery cover comprising a fixing portion received in the groove of the housing, the receiving hole of the housing being in communication with the groove, the fixing portion of the battery cover having a hollow defined therein, the battery cover latching mechanism comprising: a button having an inclined surface, the button being received in the receiving hole of the housing; the housing defining a cavity for receiving a battery at a first side thereof and two slots at one end of the cavity, the groove being defined adjacent to an opposite end of the cavity, the groove being formed between the cavity and the receiving hole, the groove forming a hollow block on an opposite second side of the housing, the hollow block defining a cutout therein to communicate the groove and the receiving hole, two symmetrical strips respectively extending from two sides of the cutout are formed on the second side of the housing, two resisting blocks, which are spaced to each other, being formed opposite to the cutout, two guiding slots being defined in the strips; a locking member slidably mounted in the housing, the locking member comprising a base board, the base board having two guiding hooks formed at two respective ends thereof, each guiding hook being configured for slidably engaging with the housing, the base board having a slanted surface and having a claw corresponding to the hollow of the fixing portion; and an elastic member being configured for providing an elastic force for returning the locking member to an original position thereof; wherein the inclined surface of the button engages with the slanted surface of the locking member. 2. The battery cover latching mechanism as claimed in claim 1, wherein the housing has two guiding slots respectively engaging with a corresponding guiding hook of the locking member. 3. The battery cover latching mechanism as claimed in claim 1, wherein the button comprises a pressing portion, a flange portion, and two extending walls with said inclined surface, the receiving hole of the housing is larger than the pressing portion and smaller than the flange portion. 4. The battery cover latching mechanism as claimed in claim 3, wherein the button has a first pole mounted between the two extending walls, the latching mechanism further comprises another elastic member resisting the blocks and surrounding the first pole for returning the button to an original position. 5. The battery cover latching mechanism as claimed in claim 1, wherein the claw and a second pole are formed at two other ends of the base board, the elastic member surrounds the second pole. 6. The battery cover latching mechanism as claimed in claim 4, wherein the base board defines a protruding hole and two inserting slots parallel to the axis of the pole, the first pole and the extending walls are respectively inserted into the protruding hole and the inserting slots, and protrude out from the protruding hole and the inserting slots.
