Patent ID: 8827323

Claim:
A chassis assembly, comprising: a main housing ( 2 ) having a side plate ( 22 ), the side plate having a track portion ( 222 ) defined on an inner surface of the side plate ( 22 ), and a hole ( 221 B) disposed on the side plate ( 22 ) in a sliding path defined by the track portion ( 222 ); a cover unit ( 3 ) detachably coupleable to the main housing, including: a pair of stator portions ( 31 ) spacedly arranged at an edge that faces the slide plate ( 22 ), and a block portion ( 32 ) consisting essentially of a wedge-shaped planar body protruding from a side edge thereof and arranged between the stator portions ( 31 ), and provided with an inclined surface ( 321 ) and a stopper surface ( 322 ); and a latching module ( 1 ) slidable on the side plate between a locked position and an released position, including: a first locking member ( 10 ) consisting essentially of a plate body ( 101 ) being bent to form a pair of substantially coplanar locking hooks ( 103 ) arranged along the sliding direction of the latching module, both hooks pointing toward the locked position, configured to respectively engage with the stator portions of the cover unit, wherein the first locking member has a through hole ( 105 ) arranged thereon in corresponding alignment with the hole ( 221 B) on the side plate, so as to allow penetration of the block portion through the hole ( 221 B) and the through hole ( 105 ) in the locked position, and a second locking member ( 12 ) coupleable to the first locking member from an outer surface of the side plate and sandwiching the side plate with the first locking member, including: an exposed operable push portion ( 122 ) configured to receive an external force substantially coplanar with the plate body of the locking hooks ( 103 ), and a tongue portion ( 123 ) having a free end ( 1231 ), arranged between the locking hooks along the sliding direction and positioned in correspondence to the block portion of the cover unit for creating interference with the block portion ( 32 ), and the tongue portion ( 123 ) configured to: ride on the inclined-surface ( 321 ) of the block portion and be raised thereby as the latching module slides from the locked position toward the released position; enable the free end ( 1231 ) thereof to abut against the stopper surface ( 322 ) upon traveling the inclined-surface ( 321 ); and retain the latching module at the released position.
