Enclosure for electronic device

A latch apparatus to latch a cover to a chassis, the latch apparatus comprising:

• a first latch mechanism comprising a latching member movably mounted to the cover between a lock position and an unlock position, thereby operable to releasably engage with a first edge of the chassis;
• a second latch mechanism comprising a plurality of locking members each moveably mounted to the cover between a lock position and an unlock position, thereby operable to releasably engage with a second edge of the chassis adjoining the first edge;
• a driving mechanism connected to the first latch mechanism and the second mechanism;
• a bracket fixed to the cover;
• and
• a drive link pivotably mounted to the bracket, and connected to the driving mechanism and the second latch mechanism;
• wherein the driving mechanism is manipulated to cause movements of the first latch mechanism and the second latch mechanism;
• wherein the driving mechanism comprises a driving member slidably mounted to the bracket, and a manipulating member pivotably connected to the bracket and the driving member, the driving member defines two oblong holes in opposite sides, the manipulating comprises two pivoting posts pivotably engaged with the bracket, and two positioning posts adjacent to the corresponding pivoting posts to be movably received in the corresponding oblong holes;
• and
• wherein the second latch mechanism further comprises a plurality of first resilient members disposed between the cover and the plurality of the locking members, to urge the plurality of locking members towards the unlock position, and the driving mechanism operates the plurality of looking members by the drive link to rotate towards the lock position overcoming the rebounding force of the plurality of first resilient members.

An enclosure for an electronic device, comprising:

• a chassis defining an opening in a side;
• a cover attached to the chassis to shield the opening of the chassis;
• and
• a latch apparatus mounted to the cover, and comprising:
• two first latch mechanisms;
• two second latch mechanisms;
• and
• a driving mechanism connected to the first latch mechanisms and the second mechanisms;
• wherein the latch apparatus further comprises a bracket fixed to the cover, the driving mechanism comprises a driving member slidably mounted to the bracket, and a manipulating member connected to the bracket and the driving member, and pivotable between a close position, where the first latch mechanisms and the second latch mechanisms are driven to correspondingly securely engage with a first edge and two opposite second edges of the chassis adjoining the first edge at the opening, and an open position, where the first latch mechanisms and the second latch mechanisms are disengaged from the chassis, the pivoting movement of the manipulating member causes a sliding movement of the driving member;
• wherein each of the first latch mechanisms comprises a latching member slidably mounted to the cover, and a first resilient member resisted between the latching member and the cover, wherein the first resilient members of the two first latch mechanisms urge the corresponding latching members to lock positions in response to the manipulating member being pivoted to the closed position, wherein the driving member urges the latching members to unlocking positions overcoming rebounding force of the corresponding first resilient members in response to the manipulating member being pivoted to the open position;
• wherein each of the latching members comprises a sliding bar slidably mounted to the bracket, and an abutting portion extending from the sliding bar along a slanting direction relative to a sliding direction of the sliding bar, the driving member comprises two ear portions abutting against the corresponding abutting portions of the latching members.
