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 is compressed when the cover member is latched to the housing member. The cover can be detached from the housing either by a movement of the latch member driven by the return member or by another movement further compressing the return member.

What is claimed is: 1. A battery cover latching mechanism, comprising: a cover member comprising a first latch portion, retaining portions, and a release portion; a housing member mating with the cover member and comprising retaining blocks; a latch base securely attached to the housing member; a l
What is claimed is: 1. A battery cover latching mechanism, comprising: a cover member comprising a first latch portion, retaining portions, and a release portion; a housing member mating with the cover member and comprising retaining blocks; 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 second latch portion; and a return member decompressed and the retaining portions engaging with the retaining blocks when the cover member is latched to the housing member, the latching member moving between a movable position, detaching the engagement of the first latch portion and the second latch portion, and a non-movable position, the return member configured to bias the latch member toward the non-movable position; wherein the first latch portion is latched to the second latch portion when the cover member is latched to the housing member, during pushing of the latch member into the housing member, the cover member can be detached from the housing member either by a movement of the latch member driven by a releasing of the compressed return member and the resisting of the second latch portion against the first latch portion; or by another movement of the latch member to further compress the return member, during which the latch member moves towards the release portion and the release portion releases the cover member from the housing member; wherein, the 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 latch member further comprises a clasp portion, the clasp portion configured for clasping the latch member to the latch base. 3. The battery cover latching mechanism as claimed in claim 2, wherein the return member is a coil spring positioned between the latch base and the latch member, 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 clasp portion, the second latch portion and the position portion arranged on a side of the latch member; the latch base defining a blind hole; and 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 latching portion comprises a first inclined wall; the release portion comprises a third inclined wall; the second latch portion comprises a second inclined wall facing the latch member and a fourth inclined wall opposite to the second inclined wall, the second inclined wall configured for sliding along the first inclined wall when the cover member is latched to or detached from the housing member, and the fourth inclined wall can slide along the third inclined wall when the cover member is detached from the housing member. 8. The battery cover latching mechanism as claimed in claim 7, wherein the second latch portion is configured for being driven by the return member, the second latch portion is driven to lift the first latching portion and detach the cover member away from the housing member. 9. The battery cover latching mechanism as claimed in claim 8, 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. 10. A portable electronic device, comprising: a cover comprising a first latch portion, retaining portions, and a release portion; a housing mating with the cover and comprising retaining blocks; 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 second latch portion; and a return member decompressed and the retaining portions engaging with the retaining blocks when the cover member is latched to the housing member, the latching member moving between a movable position, detaching the engagement of the first latch portion and the second latch portion, and a non-movable position, the return member configured to bias the latch member toward the non-movable position; wherein the first latch portion is latched to the second latch portion when the cover is latched to the housing, during pushing of the latch member into the housing member, the cover can be detached from the housing either by a movement of the latch member driven by a releasing of the compressed return member and the resisting of the second latch portion against the first latch portion; or by another movement of the latch member to further compress the return member, during which the latch member moves towards the release portion and the release portion releases the cover member from the housing member; wherein, the 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. 11. The portable electronic device as claimed in claim 10, wherein the latch member further comprises a clasp portion, the clasp portion configured for clasping the latch member to the latch base. 12. The portable electronic device as claimed in claim 11, wherein the return member is a coil spring positioned between the latch base and the latch member, 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. 13. The portable electronic device as claimed in claim 12, wherein: the clasp portion, the second latch portion and the position portion are arranged on a side of the latch member; the latch base defining a blind hole; and the coil spring received in the blind hole and compressed between the latch member and the latch base. 14. The portable electronic device as claimed in claim 10, 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. 15. The portable electronic device as claimed in claim 14, 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. 16.
