Lid controlling apparatus and rod driving device thereof

A lid controlling apparatus comprising:

• a casing having a target region formed thereon;
• a lid for covering the target region;
• and
• a rod driving mechanism connected between the casing and the lid, the rod driving mechanism comprising:
• a first rod pivotally connected to the casing;
• a non-rotatable gear fixed to the casing;
• a driven gear pivoted to a side of the first rod and connected to the lid to make the lid rotatable with rotation of the driven gear;
• and
• a planetary gear device comprising:
• a planetary gear pivoted to the side of the first rod and engaged with the non-rotatable gear for rotating between a lifting position and a closed position along the non-rotatable gear;
• and
• at least one transmission gear engaged with the planetary gear and the driven gear, a diameter of the at least one transmission gear and a diameter of the planetary gear being equal to a width of the first rod, and the first rod pivoting together with rotation of the planetary gear and the planetary gear rotating the driven gear via the at least one transmission gear when the planetary gear rotates to the lifting position or the closed position along the non-rotatable gear;
• wherein when the planetary gear device rotates to the lifting position along the non-rotatable gear, the first rod pivots together with rotation of the planetary gear device to have a first included angle relative to the casing and the planetary gear device rotates the driven gear to make the lid have a second included angle relative to the first rod;
• when the planetary gear device rotates to the closed position along the non-rotatable gear, the first rod pivots together with rotation of the planetary gear device to be contained in the casing and the planetary gear device rotates the driven gear to make the lid cover the target region.
