FIG. 2 is an assembled view of the battery of FIG. 1.
FIG. 3 is a similar to FIG. 2, but showing a using state of the battery.



DETAILED DESCRIPTION
Referring to FIG. 1, an exemplary embodiment of a portable electronic device battery 1, such as a mobile phone battery, includes a battery body 3 and a protecting structure 2.
The battery body 3 is a substantially rectangle-shaped, and includes a first side wall 30, a second side wall 36 perpendicularly connected to a first end of the first side wall 30, and a third side wall 38 perpendicularly connected to a first side of the first side wall 30 and perpendicularly connected to the second side wall 36. A first electric pole 31, a second electric pole 32, and a third electric pole 33 are formed on the first side wall 30, adjacent to a second end opposite to the first end of the first side wall 30. The first electric pole 31, the second electric pole 32, and the third electric pole 33 charge or discharge for the battery body 3. The third electric pole 33 is located between the first electric pole 31 and the second electric pole 33. The first electric pole 31 is a positive electric pole. The second electric pole 32 is a negative electric pole. The third electric pole 33 is a preset electric pole, and function of the third electric pole 33 can be defined according to need. A T-shaped sliding groove 34 is defined in the third side wall 38 of the battery body 3, through the first side wall 30. A great end of the sliding groove 34 is opposite to the first side wall 30. A supporting tab 35 extends from a second side opposite to the first side of the first side wall 30, perpendicular to the second side wall 36. A resisting tab 37 extends from the second side wall 36, adjacent to and perpendicular to the first side wall 30. A protrusion 371 protrudes from the resisting tab 37 towards the supporting tab 35.
The protecting structure 2 includes an elastic member (e.g., a spring 24), a protecting piece 21, a connecting portion 23, and a movement block 22. The protecting piece 21 is substantially L-shaped, and includes a horizontal long pole 211 and a vertical short pole 212 perpendicularly extending from a first end of the long pole 211. The short pole 212 is used to cover the second electric pole 32. A first terminal of the spring 24 is fixed to a second end opposite to the first end of the long pole 211. The movement block 22 is substantially T-shaped, to be elastically slidably engaged in the sliding groove 34. A first end of the connecting portion 23 is rotatably connected to a bottom of the movement block 22, and a second end of the connecting portion 23 is rotatably connected to a center of the long pole 211 of the protecting piece 21. The connecting portion 23 can be connected to the movement block 22 and the protecting piece 21 via hinges. The technology of rotatably connecting the connecting portion 23 to the movement block 22, and rotatably connecting the connecting portion 23 to the protecting piece 21 is known.
Referring to FIG. 2, in assembly, the movement block 22 is inserted into the sliding groove 34. The long pole 211 of the protecting piece 21 is supported on the supporting tab 35. A second terminal of the spring 24 is fitted about the protrusion 371. The short pole 212 of the protecting piece 21 covers the second electric pole 32. The portable electronic device battery 1 is at an unused state. The first electric pole 31 and the second electric pole 32 of the battery body 3 will not be short-circuited.
Referring to FIG. 3, in use, a battery accommodating body of the portable electronic device receives the battery 1. Three metal pieces are set on the battery accommodating body of the portable electronic device, respectively to the first electric pole 31, the second electric pole 32, and the third electric pole 33 of the battery 1. A drive portion is set on the battery accommodating body. When the battery 1 is inserted into the battery accommodating body of the portable electronic device, the drive portion is inserted into the gliding groove 34, to drive the movement block 22 to move towards the bottom of the sliding groove 34. Therefore, the connecting portion 23 gradually moves to overlap the long pole 211 of the protecting piece 21, to drive the long pole 211 to move towards the tab 37 on the supporting tab 35, at the same time, the spring 24 is compressed. When the movement block 22 moves to the bottom of the sliding groove 34, the short pole 212 of the protecting piece 21 moves away from the second electric pole 32 to expose the second electric pole 32. The metal pieces of the battery accommodating body are electrically connected to the first electric pole 31, the second electric pole 32, and the third electric pole 33, respectively.
The movement block 22 of the battery 1 can slide relative to the battery body 3, to drive the protecting piece 21 covers or exposes the second electric pole 32. The battery 1 can avoid short-circuit in an unused state.
The foregoing description of the exemplary embodiments of the disclosure has been presented only for the purposes of illustration and description and is not intended to be exhaustive or to limit the disclosure to the precise forms disclosed. Many modifications and variations are possible in light of the above teaching.
