DESCRIPTION OF EMBODIMENTS

FIG. 2 is a schematic diagram illustrating a case structure for a server according to an embodiment of the present invention. FIG. 3 is a schematic diagram illustrating a bottom of the second plate of FIG. 2. FIG. 4 is a cross-sectional view of a case structure for a server according to an embodiment of the present invention. In the present embodiment, a rack mountable server is taken as an example, which may include a control circuit board, a plurality of slots for accommodating plug & play hard drives and a casing. Though the rack mountable server is not illustrated in detail in the present embodiment, those skilled in the art may refer to the illustration of FIG. 1 for a reference.

Referring to FIG. 2, the case structure 200 of a server includes a first plate 210 and a second plate 220. The first plate 210 may be a top plate of a server casing 202, and the second plate 220 may be a front top cover disposed on the first plate 210. Next, referring to FIG. 2 and FIG. 4, the first plate 210 has a fixing pillar 212. The fixing pillar 212 is fixed on a top surface of the first plate 210 and protrudes from the top surface, and the fixing pillar 212 has an engaging portion 214 which may be an annular slot with an incision depth, or the fixing pillar 212 may have a gap on its edge located adjacent to a fixing rack 230, used for locking the fixing rack 230 of the second plate 220.

Next, referring to FIG. 3 and FIG. 4, the second plate 220 has the fixing rack 230 and an assembly spring 240 on its bottom. The fixing rack 230 may be integrally formed with the second plate 220, and has a locking portion 232 (for example, a V-shape slot) used for locking the engaging portion 214 of the fixing pillar 212, so as to fix the second plate 220 to an assembly position A. An opening width at a tip end of the V-shape slot is less than that at an opening end of the V-shape slot, and therefore when the second plate 220 moves along a horizontal moving direction relative to the fixing pillar 212, the fixing pillar 212 may move from the opening end of the V-shape slot to the tip end of the V-shape slot, so as to fix the engaging portion 214 of the fixing pillar 212 to the tip end of the V-shape slot. Moreover, in absence of external force, the assembly spring 240 may normally rely on the fixing rack 230. The assembly spring 240 has a lock cooperating hole 242 located above the locking portion 232, which is used for being penetrated the fixing pillar 212 to confine a horizontal movement of the second plate 220 relative to the first plate 210.

As described above, the assembly spring 240 may be a metal elastic element having an elasticity restoring ability. The assembly spring 240 has an elastic bending part C. The fixing rack 230 may has a slot P, such that the elastic bending part C may extend outside the slot P to form an activating end 244. Referring to FIG. 5 and FIG. 6, FIG. 5 and FIG. 6 are cross-sectional views of the assembly spring and the second plate of FIG. 4 when being activated by forces. When assembly spring 240 is activated by forces and departs from the fixing pillar 212, the activating end 244 is pushed upwards for a distance, and when the lock cooperating hole 242 of the assembly spring 240 is not interfered with the fixing pillar 212, the fixing rack 230 may be released from the fixing pillar 212 by moving the second plate 220 along the horizontal moving direction to depart from the fixing pillar 212, and accordingly, the second plate 220 may move from the original assembly position A to a disassembly position B, and departs from the first plate 210.

According to the above description, when the second plate 220 is assembled to the first plate 210 or disassembled from the first plate 210, fixing/releasing of the second plate 220 may be performed simply via operation of the fixing rack 230 and the assembly spring 240. Therefore, the case structure provided by the present invention is convenient in utilization and may substitute the conventional complicated fixing/releasing structure for assembly/disassembly of the front cover.

Moreover, compared to the conventional techniques, the fixing pillar 212 (for example, bolt or rivet) fixed between the first plate 210 and the second plate 220 may further enhance a structural strength of the second plate 220. Referring to FIG. 3, the second plate 220 may have two sidewalls 222 and a middle flat part 224 located between the two sidewalls 222. The structural strength of the middle flat part 224 is relatively poor compared with that of the two sidewalls 222. Allocation of the fixing rack 230 and the assemble spring 240 on the middle flat part 224 of the second plate 220 is not only convenient for operation and observation, but may also improve a support to the second plate 220 via the fixing pillar 212 of the first plate 210, such that the structural strength of the whole case structure 200 may be enhanced accordingly.

In addition, in the above embodiment, the first plate 210 of FIG. 4 may also be a bottom plate or a plate of other parts of the server casing 202 besides just being the top plate. The first plate 210 may lock the second plate 220 by engaging the fixing pillar 212 with the locking portion 232 (for example, a V-shape slot).

As to the structure and shape of the locking portion, the present invention provides another embodiment which may achieve a same function as that of the above embodiment. FIG. 7 is a schematic diagram illustrating a bottom of a second plate. Referring to FIG. 7, the second plate 220 has a fixing rack 230 and an assembly spring 240 on its bottom. The fixing rack 230 has a locking portion 234 (for example, a gourdshaped hole) disposed along a horizontal moving direction, which is used for locking the engaging portion 214 of the fixing pillar 212 of FIG. 4 to fix the second plate 220. In the present embodiment, an opening width of the locking portion 234 at a first position D1 is different from that at a second position D2. Namely, the opening width of the second position D2 allows the fixing pillar 212 vertically penetrating through, and the opening width of the first position D1 may only allow the engaging portion 214 of the fixing pillar 212 horizontally passing through for engaging the fixing pillar 212, such that a vertical movement of the second plate 220 relative to the first plate 210 is confined. Moreover, the assembly spring 240 has a lock cooperating hole 242 located corresponding to the first position D1 of the locking portion 234, which is used for being penetrated by the fixing pillar 212 to confine a horizontal movement of the second plate 220 relative to the first plate 210. In summary, the case structure of the server of the present invention has a simplified fixing/releasing structure, which may effectively improve a convenience of assembly. Therefore, a user may swiftly assemble or disassemble the second plate without the aid of tools, which is very convenient for application.

It will be apparent to those skilled in the art that various modifications and variations can be made to the structure of the present invention without departing from the scope or spirit of the invention. In view of the foregoing, it is intended that the present invention cover modifications and variations of this invention provided they fall within the scope of the following claims and their equivalents.
