BACKGROUND OF THE INVENTION1. Field of the Invention
The present invention relates to a server chassis, more particularly, to a server chassis which is fit for hard disks with different sizes.
2. Description of the Related Art
In general, servers could be divided into three types such as the tower server, the rack server and the blade server from the structures. For the rack server, it is assembled on the rails of the two sides of the rack; its chassis is generally a rectangular structure, and its height is generally from 1U to 5U (1U=1.75 inches=44.45 millimeters). For conveniently repairing, the chassis of the rack server could be divided into the chassis body and the top cap. For conveniently assembling the rack server on the rack, the hard disks would be performed hot plugging from the front panel, such that the hard disk cage assembling the hard disks generally would install in the front end of the chassis, and the upper surface of the hard disk cage would cooperate with the top cover for shielding the upper portion of the chassis.
For reducing the development and fabrication cost, the development of one chassis would tend to be timely fit different configurations in recently. For servers, theirs hard disks have many specifications such as 2.5 inches and 3.5 inches. Hard disks with different specifications fit for hard disk cages with different sizes. Since the length of the hard disks is different, namely, the size of the upper surface of the 2.5-inch hard disk should smaller than the size of the upper surface of the 3.5-inch hard disk at the direction of the length, such that a problem would be caused, that is, a gap would be formed on the top portion of the chassis when the top cover cooperated with the upper surface of the 3.5-inch hard disk assembles with the 2.5-inch hard disk cage, such that the components in the chassis would be exposed to outside so as to cause the problems of the interference of electromagnetic wave or the leakage of the electromagnetic wave, the noise and the dust. For resolving the above-mentioned problems, let the 2.5-inch hard disk cage and 3.5-inch hard disk cage can be cooperated with the same top cover. When the server assembles on the 2.5-inch hard disk cage, an another independent top cover would be generally added to assemble between the upper wall of the 2.5-inch hard disk cage and the top cover, so as to shield the gap formed on the top portion of the chassis. However, such solution causes that the top cover would be divided into two parts with different sizes in the structure, and thus failing to form an integral whole. Accordingly, on the one hand the fabrication cost would increase and thus increasing the assembly steps and time, and on the other hand, since the top cover is assembled by many parts, so as to increase the risk of the interference of electromagnetic wave or the leakage of the electromagnetic wave.
In summary, it has become a problem to be solved in the industry as to how to design a server chassis which is fit for hard disks with different sizes; and capable of realizing the integral whole assembly, and resolving the problems the interference of electromagnetic wave or the leakage of the electromagnetic wave at the same time.

In addition, referring to
In details, when the top cover 120 moves along a assembly direction PI and combines with the upper surface 110 of the hard disk cage 140 to form a chassis body, the first embedded portions 110a and the second embedded portions 120a are staggered. The first embedded portions 110a insert into corresponding second slots S2 and the second embedded portions 120a insert into corresponding first slots S1 so as to prevent the interference of an electromagnetic wave that transmits through the boundary of the first side D1 and the second side D2 into the interior of the chassis.
As shown in
In addition, when the top cover 120 and the upper surface 110 of the hard disk cage 140 are combined to form a chassis body, a hole of the upper surface 110 of the hard disk cage 140 overlaps a hole of the top cover 120 to form a fixing hole, through which a fastener (for example, a screw) is mounted on the chassis body. In the present embodiment, the hole of the upper surface 110 of the hard disk cage 140 is disposed, for example, on the first embedded portions 110a. The number of the screws is more than one to enhance the locking force. The screw minimizes a tolerance of a gap between the upper surface 110 of the hard disk cage 140 and the top cover 120. This is to say, the upper surface 110 of the hard disk cage 140 and the top cover 120 tightly combine to avoid the electromagnetic wave transmitting through the gap smoothly.
