Communication device and ejection mechanism

An ejection mechanism for ejecting a card, the ejecting mechanism comprising:

• a bottom cover comprising a first sidewall and a second sidewall opposite to the first sidewall, the second sidewall defining an opening for inserting the card;
• a sliding assembly comprising a sliding block, an elastic member and an elastic rod, the sliding block defining a containing groove which is divided into an insertion rail and an ejection rail, the sliding block configured to move back and forth between the first and second sidewalls, a first distal end of the elastic rod fixed in a fixing hole of the first sidewall, a second distal end of the elastic rod received in the containing groove and configured for sliding in the containing groove;
• and
• a top cover configured for engaging with the bottom cover to receive the sliding assembly;
• wherein when the card is inserted into the ejection mechanism via the opening by an external force, the sliding block moves towards the first sidewall in unison with the card, the elastic member is compressed, and the second distal end of the elastic rod slides along the insertion rail until the second distal end of the elastic rod is locked in a joint of the insertion and ejection rails, and then the external force is released, and a distal end of the card is exposed outside the ejection mechanism;
• when another external force is applied to the distal end of the card exposed outside the opening to drive the card to move towards the first sidewall, and the second distal end of the elastic rod disengages from the locking position, then the compressed elastic member drives the sliding block to move towards the opening, the second distal end of the elastic rod slides in the ejection rail, and the card moves towards the opening and is ejected from the ejection mechanism.
