Patent ID: 8749958

Claim:
A portable electronic device, comprising: a main body defining a plurality of mounting holes at corners thereof; a plurality of mounting modules; a plurality of resilient members compressed and mounted in the mounting holes of the main body by the corresponding mounting modules; and a control module, wherein the control module controls the mounting modules to release the compressed resilient members to eject the resilient members from the main body when a real-time acceleration value is larger than a critical acceleration value; wherein each mounting module comprises a latching unit and an actuating unit; the latching unit comprises a latching member and a container to receive the corresponding resilient member; the container comprises a base, a sidewall extending from a periphery of the base, the base and the sidewall cooperatively defining an opening facing the corresponding mounting hole, and a latching hole defined in the sidewall adjacent to the opening; the latching member defines a latching protrusion at a side thereof engaged in the latching hole; the actuating unit releases the resilient members from the containers by pressing the latching protrusions to be detached from the latching holes.
