Disk array enclosure having linkage structure for opening door covers without interference

A disk array enclosure, comprising:

• a plurality of hard disk accommodating structures for accommodating hard disks, the plurality of hard disk accommodating structures being arranged side by side, each of the plurality of hard disk accommodating structures having a front opening, a rear opening, and a connecting side portion, the connecting side portion being located on one side of the front opening and the rear opening;
• a retaining member mounted to one side of the plurality of hard disk accommodating structures and at a position corresponding to the rear openings of the plurality of hard disk accommodating structures;
• a plurality of door covers corresponding to the front openings of the plurality of hard disk accommodating structures, respectively, wherein one end of each of the plurality of door covers is pivotally connected to the connecting side portion so that each of the plurality of door covers is pivotable relative to the connecting side portion, and a top side of each of the plurality of door covers has a slide hole;
• and
• a plurality of connecting rod assemblies disposed in the plurality of hard disk accommodating structures, respectively, and each of the plurality of connecting rod assemblies including a first rod and a second rod, the first rod having a first end that is movably disposed in the slide hole and a second end that extends towards the retaining member and that has a pushing member, the second rod having a first end that is pivotally connected to the first rod and a second end that is pivotally connected to the connecting side portion,
• wherein, when a door cover, among the plurality of door covers, is opened, the first end of the first rod is moved outwardly along the slide hole in response to a movement of the door cover, and the pushing member at the second end of the first rod is simultaneously moved outwardly, and the second rod is pivoted in response to the movement of the first rod,
• the door cover is flush with the connecting side portion when the first end of the first rod is moved to one end of the slide hole,
• the first rod has a first section and a second section that are arranged in sequence,
• the first section has one end movably disposed in the slide hole and another end having a first curved portion that is concave,
• the second section has one end provided with the pushing member and another end having a second curved portion that is convex,
• the second curved portion is connected to the first curved portion, and
• the first end of the second rod is pivotally connected to a junction of the first curved portion and the second curved portion.
