Systems and methods for cover assembly retention of a portable electronic device

A cover assembly for an electronic device comprising:

• a main plate comprising:
• an inner surface;
• an outer surface;
• a first side edge;
• and
• a second side edge;
• at least one fastener plate, wherein the at least one fastener plate is coupled to the inner surface and adjacent the first side edge of the main plate;
• and
• at least one retention feature coupled to the inner surface and adjacent the second side edge of the main plate, wherein the at least one retention feature comprises:
• a first side wall that protrudes away from the main plate;
• a second side wall that protrudes away from the main plate, the second side wall adjacent to the first side wall;
• and
• a flange portion coupled to the first side wall and the second side wall, wherein the flange portion is substantially parallel to and offset from the main plate.

A cover assembly for an electronic device, the cover assembly comprising:

• a housing comprising at least one detent;
• and
• a back cover assembly comprising at least one detent feature, wherein the at least one detent feature is operable to pass the at least one detent during a coupling of the back cover assembly to the housing, such that after the coupling, the at least one detent feature does not travel backwards to pass the at least one detent a second time, thereby providing a coupling action between the back cover assembly and the housing, wherein:
• the at least one detent comprises a detent spring;
• and
• the at least one detent feature comprises a pin.

A cover assembly for an electronic device, the cover assembly comprising:

• a housing comprising at least one detent;
• and
• a back cover assembly comprising at least one detent feature, wherein the at least one detent feature is operable to pass the at least one detent during a coupling of the back cover assembly to the housing, such that after the coupling, the at least one detent feature does not travel backwards to pass the at least one detent a second time, thereby providing a coupling action between the back cover assembly and the housing, wherein the at least one detent comprises a pawl, wherein the at least one detent feature comprises a latch, and wherein the housing further comprises:
• a hinge coupling the pawl to the housing, wherein:
• the hinge rotates the pawl to allow the latch to pass the pawl during the coupling of the back cover assembly to the housing;
• and
• the hinge does not rotate the pawl after the latch has initially passed the pawl, thereby providing a coupling action between the back cover assembly and the housing.
