Patent ID: 8241778

Claim:
A portable electronic device battery comprising: a battery body comprising: a first side wall; a positive electric pole formed on the first side wall; a negative electric pole formed on the first side wall; and a supporting tab extending from the first side wall; a second side wall perpendicularly connected to a first end of the first side wall; a resisting tab extended from an end of the second side wall, adjacent to and perpendicular to the first side wall; a third side wall perpendicularly connected to the first side wall and the second side wall; a sliding groove defined in the third side wall and extending through the first side wall; and a protecting structure slidably mounted to the battery body, the protecting structure comprising: a protecting piece to cover one of the positive and negative electric poles, wherein the protecting piece is substantially L-shaped and comprises a long pole supported on the supporting tab and a short pole perpendicularly extending from a first end of the long pole; a resilient member, wherein a first terminal of the resilient member is fixed to a second end opposite to the first end of the long pole, and a second terminal of the resilient member is connected to the resisting tab; a connecting portion, wherein a first end of the connecting portion is rotatably connected to the movement block, and a second end opposite to the first end of the connecting portion is rotatably connected to the long pole of the protecting piece; and a movement block, wherein the movement block is movably engaged in the sliding groove, when the movement block moves towards the bottom of the sliding groove, the connecting portion gradually moves to overlap the long pole of the protecting piece, to drive the long pole to move towards the resisting tab on the supporting tab, the resilient member is compressed, when the movement block moves to the bottom of the sliding groove, the short pole of the protecting piece is operable to expose one of the positive and negative electric poles.
