Electronic device with a battery fastening mechanism

An electronic device comprising:

• a battery module having a coupling surface;
• a housing having a first panel that is parallel to said coupling surface and that is formed with at least one opening, and a second panel that extends inwardly and perpendicularly from said first panel;
• and
• at least one fastening mechanism having
• a fixing portion that extends from said coupling surface of said battery module and that engages removably said at least one opening,
• a first fastening portion that is disposed on said fixing portion,
• a cantilever that is flexible, that is formed in said second panel, and that has a free end segment proximate to said first panel, a fixed end segment distal from said first panel, a first surface adjacent to said fixing portion, and a second surface opposite to said first surface,
• a second fastening portion disposed on said first surface, adjacent to said free end segment, and engaging removably said first fastening portion, and
• a protrusion formed on said first surface and adjacent to said fixed end segment;
• wherein said free end segment of said cantilever is urged by said fixing portion to bend away from said fixing portion during movement of said fixing portion from a disengaged position toward a engaged position via said at least one opening, and restores to engage said second fastening portion with said first fastening portion when said fixing portion is moved to the engaged position;
• and
• wherein said free end segment of said cantilever is operable to bend away from said fixing portion, such that said second fastening portion is disengaged from said first fastening portion, and that said fixing portion is urged by said protrusion to move from the engaged position to the disengaged position to be disengaged from said at least one opening.
