Self-locking and foldable ejector arm

A system comprising:

• a computing device including a plurality of ports on a front face of the computing device;
• and
• a locking mechanism on the front face of the computing device, the locking mechanism comprising:
• a jaw configured to secure the computing device in an enclosure;
• a transmission lever comprising an arm pivot at a first end and an actuating pivot at a second end;
• an arm configured to rotate about the arm pivot away from the plurality of ports, the arm being selectively decoupled from the transmission lever;
• and
• a wedge configured to bias against the jaw and lock the jaw against the enclosure when the arm rotates towards the plurality of ports,
• wherein when the arm is coupled to the transmission lever, rotating the arm away from the plurality of ports causes the transmission lever to rotate about the actuating pivot and release the jaw from the enclosure, enabling the computing device to be removed from the enclosure,
• wherein the transmission lever includes an unlocking slope configured to contact an unlocking surface on the wedge, wherein rotating the arm away from the plurality of ports when the arm is coupled to the transmission lever releases the jaw from the enclosure by forcing the unlocking slope of the transmission lever against the unlocking surface of the wedge.

A method comprising:

• mounting a computing device in an enclosure, the computing device including a plurality of ports on a front face of the computing device;
• rotating an arm of a locking mechanism toward the plurality of ports to lock the computing device in the enclosure, the locking mechanism comprising a transmission lever, a jaw, and a wedge such that locking the computing device in the enclosure includes preventing the jaw from further rotation with the wedge,
• coupling the arm to the transmission lever;
• wherein rotating the arm toward the plurality of ports actuates the transmission lever to secure the jaw against a portion of the enclosure;
• selectively decoupling the arm from the transmission lever;
• rotating the arm away from the plurality of ports without actuating the transmission lever to force an unlocking slope of the transmission lever against an unlocking surface of the wedge;
• and
• releasing the jaw from the portion of the enclosure to enable the computing device to be removed from the enclosure.
