Patent ID: 6947279

Claim:
A portable electronic apparatus comprising: a host module; a display module connected electrically to said host module, and having a rear side that is formed with a groove confined by a groove-defining wall; a folding pivot module interconnecting said host and display modules and including a first module member having a first pivot end portion that is connected pivotally to said host module, a second pivot end portion opposite to said first pivot end portion, and lateral end portions that interconnect said first and second pivot end portions, said first module member being formed with a receiving cavity that extends from said second pivot end portion toward said first pivot end portion and that is disposed between said lateral end portions, and a second module member having a third pivot end portion that is connected pivotally to said second pivot end portion of said first module member, and a fourth pivot end portion that is opposite to said third pivot end portion and that is connected pivotally to said display module, said second module member being pivotable relative to said first module member from an unfolded position to a folded position, where said second module member is received in said receiving cavity; and a locking unit for locking releasably said pivot module to said rear side of said display module when said second module member is in the folded position, said locking unit including a locking hole formed in one of said second pivot end portion of said first module member and said third pivot end portion of said second module member and confined by a hole-defining wall that has a periphery, and a spring-loaded latch unit for engaging releasably said locking hole, said spring-loaded latch unit including a latch member having an inner portion that extends into said groove and that is connected movably to said groove-defining wall, and an outer portion that is disposed externally of said groove, wherein, when said second module member is in the folded position, and said first module member is rotated to dispose said pivot module on said rear side of said display module, said periphery of said hole-defining wall abuts against said outer portion of said latch member until said locking hole is aligned with said latch member, during which time said outer portion of said latch member extends into said locking hole to retain releasably said pivot module on said rear side of said display module.
