The top cover includes at least two cover plates that are sequentially connected. When the connecting end 32 is fixedly connected to the other end of the top of the base 100, the top cover has at least two cover plates that are sequentially unfolded to close the top of the chassis in an unfolded state. When the connecting end 32 is detached from the other end of the top of the base 100, the top cover has at least two cover plates that are folded and retracted to open the top of the chassis in a folded state.

[0049] The rotating end 21 of the top cover is rotatably connected to one end of the top of the base 100, and the connecting end 32 of the top cover is detachably connected to the other end of the top of the base 100. When the connecting end 32 of the top cover is fixedly connected to the other end of the top of the base 100, at least two cover plates of the top cover are sequentially unfolded to close the top of the chassis. The top cover is in the unfolded state, which can play a role in dust and water protection, protecting the motherboard, CPU and other electrical components inside the server chassis. When the connecting end 32 of the top cover is detached from the other end of the top of the base 100, at least two cover plates of the top cover can be folded and retracted to open the top of the chassis. The top cover is in the folded state, and the operator can perform production and subsequent maintenance on the server through the open top.

The second sliding end 41 is rotatably connected to the top of the base 100 and can slide along the top of the base 100. The third cover plate 4 is disposed between the first cover plate 2 and the second cover plate 3. The second sliding end 41 is adapted to be detachably connected to the first movable end 22 in the unfolded state and is adapted to drive the first movable end 22 to move upward when sliding towards the rotating end 21. The first sliding end 31 is adapted to be detachably connected to the second movable end 42 in the unfolded state and is adapted to drive the second movable end 42 to move upward when sliding towards the rotating end 21.

[0054] In a specific implementation, when the connecting end 32 is fixedly connected to the other end of the top of the base 100, the first sliding end 31 is fixedly connected to the second movable end 42, and the second sliding end 41 is fixedly connected to the first movable end 22; when the connecting end 32 is disassembled from the other end of the top of the base 100, the first sliding end 31 and the second sliding end 41 are disassembled in sequence, slide rotatably toward the rotating end 21 in sequence, and drive the second movable end 42 and the first movable end 22 to move upward in sequence to fold the second cover plate 3, the third cover plate 4 and the first cover plate 2.

[0063] In a preferred embodiment, the sum of the angles of the fifth included angle 423 and the sixth included angle 313 is 180°. The sixth bend 421 and the seventh bend 311 abut against each other when the third engaging part 312 and the third engaging groove 422 are engaged, allowing for better engagement. The fifth included angle 423 or the sixth included angle 313 is an acute angle. In the unfolded state, the sixth bend 421 can cover the top of the seventh bend 311, achieving better waterproof and dustproof effects. Preferably, the fifth included angle 423 is 60° and the sixth included angle 313 is 120°. The third engaging part 312 is an I-beam.

[0064] The server chassis in this embodiment also includes a first elastic element 5 and a second elastic element 6; one end of the first elastic element 5 is connected to the first sliding end 31, and the other end is connected to the bottom of the first cover plate 2, which is adapted to drive the first sliding end 31 to slide toward the rotating end 21; one end of the second elastic element 6 is connected to the second sliding end 41, and the other end is connected to the bottom of the third cover plate 4, which is adapted to drive the second sliding end 41 to slide toward the rotating end 21.

[0065] In the unfolded state, both the first elastic element 5 and the second elastic element 6 are in a stretched state. When released from the unfolded state, the elastic force of the first elastic element 5 pulls the first sliding end 31 toward the rotating end 21; the elastic force of the second elastic element 6 pulls the second sliding end 41 toward the rotating end 21.

[0066] Specifically, the first sliding end 31 is provided with a first hanging hole, and the bottom of the first cover plate 2 protrudes with a first protruding bridge 23.
