Sliding mechanism and portable electronic device having the same

A portable electronic device, comprising:

• a base;
• a first cover;
• a second cover;
• a sliding mechanism configured for slidably mounting the first cover and the second cover on the base, which comprises a base plate having a first surface, and the base plate comprising a first rotating shaft, a second rotating shaft and a third rotating shaft;
• a first sliding plate slidably mounted to the first surface, and the first sliding plate located adjacent to one side of the base plate, the first sliding plate secured to the first cover, and the first sliding plate having a first connecting shaft located between the first rotating shaft and the second rotating shaft;
• a second sliding plate slidably mounted to the first surface, and the second sliding plate located adjacent to an opposite side of the base plate, the second sliding plate secured to the second cover, and the second sliding plate having a second connecting shaft located between the first rotating shaft and the third rotating shaft;
• and
• an elastic element providing force for driving the first sliding plate and the second sliding plate to slide relative to the base plate in parallel and opposite directions with each other,
• wherein the first connecting shaft and the second connecting shaft are positioned on opposite sides of an axis along which the first rotating shaft, the second rotating shaft, and the third rotating shaft lie, the elastic element is substantially S-shaped and is fixed to the second rotating shaft, the first connecting shaft, the first rotating shaft, the second connecting shaft, and the third rotating shaft in turn.
