Electronic device with cover ejection mechanism

An electronic device comprising:

• a main body comprising a guiding portion;
• a back cover rotatably connected to the main body, and configured for receiving a battery;
• and
• a cover ejection mechanism comprising:
• an ejection member slidably connected to the guiding portion, and comprising a sliding block defining an inclined surface;
• and
• a locking member slidably connected to the main body, and comprising:
• a locking element defining a first inclined surface and a second inclined surface connected to the first inclined surface;
• and
• an elastic element, wherein one end of the elastic element is fixed to the locking element, and an opposite end is fixed to a side plate of the main body;
• wherein when the back cover is rotated relative to the main body, the sliding block is pushed by the back cover to slide along the guiding portion, when the inclined surface of the sliding block touches the first inclined surface, the locking element is pushed by the sliding block to move along a direction substantially perpendicular to the guiding portion, causing the elastic element to be compressed, after the sliding block slides over the locking element, the back cover covers the main body, the elastic element rebounds to push the locking element to return to an initial position where the sliding block is blocked by the second inclined surface of the locking element, thereby preventing the back cover from disengaging from the main body.
