Electronic device

An electronic device to process default functions of the electronic device, comprising:

• a first body;
• a second body, pivotally connected to the first body, wherein the second body includes an opening on a bottom surface of the second body;
• a motherboard, disposed inside said second body, wherein said motherboard within said second body communicates the outside through said opening;
• a baffle, disposed on said bottom surface with said opening, wherein one side edge of the baffle is pivotally connected to the second body, and the baffle is able to rotate with respect to the second body;
• an elastic element with one end of the elastic element connected to the baffle and the other end of the elastic element connected to the second body;
• a pivotal rotation mechanism including:
• a first connecting piece, fixed to said bottom surface with said opening of the second body;
• and
• a second connecting piece, fixed to the baffle, wherein the first connecting piece and the second connecting piece are pivotally connected with each other via a shaft, such that the first connecting piece and the second connecting piece are able to rotate with respect to each other;
• and
• a drive mechanism, including:
• a pivot, having two ends respectively connected to the first body and the second body;
• a linkage, sleeved over the pivot;
• and
• a cam, sleeved over the linkage, and disposed corresponding to the position of the baffle;
• wherein the electronic device is arranged such that when the first body rotates with respect to the second body, the first body drives the pivot to rotate, the pivot drives the linkage to make the cam rotate, and the cam contacts and pushes the baffle and makes the baffle rotate with respect to the second body and expose part of the opening;
• wherein when the first body rotates with respect to the second body, the cam separates from the baffle, and the elastic element pull the baffle back for covering the opening;
• wherein the baffle further includes a stopper disposed on said baffle and corresponding to said second body;
• and when the baffle rotates with respect to the second body, the stopper withstands the second body, such that the baffle rotates in a limited range of angle, wherein said bottom surface with said opening of the second body further includes a plurality of pads, and the maximum distance between the baffle and the second body is shorter than the height of each of the pads.
