A battery cover latching mechanism used in portable electronic device (10) is described including a cover member (11), a housing member (12), a latch base (14), a latch member (13), and a return member (15). The latch base can be securely attached to the housing member. The latch member is mounted on the latch base and movable relative to the latch base to latch the cover member to the housing member. The return member drives the latch member to move in such a manner that the movement of the latch member detaches the cover member away from the housing member.

What is claimed is: 1. A battery cover latching mechanism, comprising: a cover member comprising a first latch portion and retaining portions; a housing member mating with the cover member and comprising retaining blocks, the retaining portions engaging with the retaining blocks when the cover member attached to the housing member; a latch base securely attached to the housing member; a latch member mounted on the latch base and movable relative to the latch base to latch the cover member to the housing member, the latch member comprising a clasp portion and a second latch portion, the clasp portion configured for clasping the latch member to the latch base, the second latch portion configured for latching the first latching portion to latch the cover member to the housing member; and a return member, the latch member moving between a movable position, detaching the engagement of the latch parts, and a non-movable position, and the return member configured to bias the latch member toward the non-movable position, wherein, when either movement of the latch member is applied, the cover member is then slid so as to disengage the retaining portions from the retaining blocks, detaching the cover member from the housing member. 2. The battery cover latching mechanism as claimed in claim 1, wherein the return member is elastic and positioned between the latch base and the latch member. 3. The battery cover latching mechanism as claimed in claim 2, wherein the return member is coil spring, the latch member further comprises a position portion, the coil spring coiling around the position portion and compressed between the latch member and the latch base. 4. The battery cover latching mechanism as claimed in claim 3, wherein: the latch member further comprise a latch member, the clasp portion, the latch portion and the position portion arranged on a side of the latch member; the latch base defining a blind hole; the coil spring received in the blind hole and compressed between the latch member and the latch base. 5. The battery cover latching mechanism as claimed in claim 1, wherein the latch base defines a clasp hole and thus forms a clasp wall, the clasp portion received in the clasp hole, movable relative to the clasp hole and clasping the clasp wall. 6. The battery cover latching mechanism as claimed in claim 5, wherein the latch base further defines a securing hole, and the housing member comprises an attaching column, the attaching column securely mounted in the securing hole. 7. The battery cover latching mechanism as claimed in claim 1, wherein: the first latch portion comprising a first inclined wall; and the second latch portion comprising a second inclined wall facing the latch member, the second inclined wall corresponding to the first inclined wall such that the first inclined wall can slide along the second inclined wall when the cover member is latched to or detached from the housing member. 8. The battery cover latching mechanism as claimed in claim 7, wherein the first latching portion comprises two latch parts and a bridge part, two opposite ends of the bridge parts connect the two latch parts respectively, the two latch parts configured for latching the second latching portion, and the first inclined wall is arranged on the two latch parts. 9. A portable electronic device, comprising: a cover comprising a first latch portion and retaining portions; a housing mating with the cover and comprising retaining blocks, the retaining portions engaging with the retaining blocks when the cover attached to the housing; a battery cover latching mechanism, comprising: a latch base securely attached to the housing; a latch member mounted on the latch base and movable relative to the latch base to latch the cover to the housing, the latch member comprising a clasp portion and a second latch portion, the clasp portion configured for clasping the latch member to the latch base, the second latch portion configured for latching the first latching portion to latch the cover to the housing; and a return member, the latch member moving between a movable position, detaching the engagement of the latch parts, and a non-movable position, and the return member configured to bias the latch member toward the non-movable position; wherein, when either movement of the latch member is applied, the cover is then slid so as to disengage the retaining portions from the retaining blocks, detaching the cover from the housing member. 10. The portable electronic device as claimed in claim 9, wherein the return member is elastic and positioned between the latch base and the latch member. 11. The portable electronic device as claimed in claim 10, wherein the return member is coil spring, the latch member further comprises a position portion, the coil spring coiling around the position portion and compressed between the latch member and the latch base. 12. The portable electronic device as claimed in claim 11, wherein: the latch member further comprise a latch member, the clasp portion, the latch portion and the position portion arranged on a side of the latch member; the latch base defining a blind hole; the coil spring received in the blind hole and compressed between the latch member and the latch base. 13. The portable electronic device as claimed in claim 9, wherein the latch base defines a clasp hole and thus forms a clasp wall, the clasp portion received in the clasp hole, movable relative to the clasp hole and clasping the clasp wall. 14. The portable electronic device as claimed in claim 13, wherein the latch base further defines a securing hole, and the housing comprises an attaching column, the attaching column securely mounted in the securing hole. 15. The portable electronic device as claimed in claim 9, wherein: the first latch portion comprising a first inclined wall; and the second latch portion comprising a second inclined wall facing the latch member, the second inclined wall corresponding to the first inclined wall such that the first inclined wall can slide along the second inclined wall when the cover is latched to or detached from the housing. 16. The portable electronic device as claimed in claim 15, wherein the first latching portion comprises two latch parts and a bridge part, two opposite ends of the bridge parts connect the two latch parts respectively, the two latch parts configured for latching the second latching portion, and the first inclined wall is arranged on the two latch parts.
