1. Technical Field
The present disclosure relates to a battery of a portable electronic device.
2. Description of Related Art
When mobile phone batteries are not in use, users usually place the batteries at some places without much attention. In certain circumstances, such as a humid environment, can short-circuit the positive and negative electric poles of a mobile phone battery.
Referring to
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
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.
