Patent ID: 8464961

Claim:
An electronic apparatus comprising: a housing defining an accommodating space therein, and an air inlet that places said accommodating space in fluid communication with the external environment; and an airflow regulating device including a cover panel for covering and uncovering said air inlet, and an actuating mechanism coupled to said cover panel and driving movement of said cover panel to adjust the degree of opening of said air inlet in response to a change in temperature in said accommodating space; wherein said airflow regulating device further includes a motor controller for controlling operation of said actuating mechanism to drive movement of said cover panel; wherein said cover panel is movably mounted to said housing, and said actuating mechanism includes a motor coupled electrically to said motor controller, a pinion connected to and driven by said motor, and a rack engaging said pinion so as to move said cover panel when said motor is actuated; and wherein said housing has a side wall that is formed with id air inlet, and a supporting bracket mounted at an inner side of said side wall, said supporting bracket being formed with an elongate guiding groove, said actuating mechanism further including a pair of linkages that cross and that are pivoted to each other, each of said linkages having a pivot end pivoted to said cover panel, and an insert end opposite to said pivot end and received slidably in said guiding groove, said rack being pivoted to said insert end of one of said linkages so as to drive sliding movement of said insert ends in said guiding groove.
