Description

server

The invention relates to a server.

The server is the core computer that serves each computer in the network system. It can provide the functions of the disk and printing services required by the network users, and also allows each client to share resources in the network environment with each other. The basic structure of the server is roughly the same as that of a general personal computer. It consists of a central processing unit (CPU), a memory, and an input/output (I/O) device, and is connected by a bus. It is connected internally, connected to the central processing unit and memory through the north bridge chip, and connected to the input/output device through the south bridge chip.

The server has undergone three evolutions in terms of the chassis structure: from the early Pedestal Server to the Rack Server, which emphasizes centralized performance, to the high-density computing blade. (Blade Server). In addition, the servo has a width of 19 inches and a height in U (1U = 1.75 inches = 44.45 mm). There are usually 1U, 2U, 3U, 4U, 5U, 7U standard servers.

In the case of a rack server, the chassis of the server is assembled by assembling the upper cover and the bottom case, and then combining with the hard disk module to form a complete server. However, the edges of the existing upper cover have members that are riveted to each other, and the existing upper cover has a large area. Therefore, when the processing of the upper cover is performed, the stress distribution of the upper cover is likely to be uneven, resulting in The upper cover is deformed or bent. In this way, when an external force is applied to the upper cover, uneven surface or wavy bending phenomenon occurs, which is called so-called oil canning, and the larger the area of the upper cover, the more likely such a drumming phenomenon occurs. . This will make it difficult to assemble the upper cover and the hard disk module, and the corresponding components will not be loaded.

The present invention provides a server that solves the problem of the drumming phenomenon of the upper cover.

The invention provides a server comprising a casing and a motherboard module. The casing has a bottom case and an upper cover. The bottom case has a bottom plate and two side plates on opposite sides of the bottom plate. The upper cover is mounted on the bottom case. The opposite sides of the upper cover are provided with two folded edges which abut against the corresponding side plates. The upper cover also has a long strip type convex hull. The convex hull extends from the side where one of the hem is located to the side where the other hem is located. The motherboard module is disposed in the bottom case. The motherboard module has a CPU.

In an embodiment of the server of the present invention, the convex hull extends in a direction perpendicular to the two side plates.

In an embodiment of the server of the present invention, the server further includes a hard disk module. The hard disk module includes a hard disk frame and a back plate. A plurality of hard disk insertion openings are formed on the front side of the hard disk module. The back plate is disposed on the rear side of the hard disk frame and perpendicular to the bottom plate. When the upper cover covers the bottom case, the convex hull is located on the back plate.

In an embodiment of the server of the present invention, the server further includes a hard disk module. The hard disk module includes a hard disk frame and a back plate. Hard disk mode The front side of the group is formed with a plurality of hard disk insertion openings. The back plate is disposed on the rear side of the hard disk frame and perpendicular to the bottom plate. When the upper cover covers the bottom case, the back plate is located between the convex hull and the hard disk frame.

In an embodiment of the server of the present invention, the server further includes a hard disk module. The hard disk module includes a hard disk frame and a back plate. A plurality of hard disk insertion openings are formed on the front side of the hard disk module. The back plate is disposed on the rear side of the hard disk frame and perpendicular to the bottom plate. The projections of the backsheet and the convex hull at least partially coincide with the projection perpendicular to the direction of the bottom plate.

In an embodiment of the server of the present invention, the convex hull extends in a direction parallel to the backing plate.

In an embodiment of the server of the present invention, the server further includes a hard disk module. The hard disk module includes a hard disk frame and a cover plate. A plurality of hard disk insertion openings are formed on the front side of the hard disk module. The cover is located on the front side of the upper cover and combined with the upper cover. The convex hull is located in the rear side region of the upper cover.

In an embodiment of the server of the present invention, the front side of the upper cover extends with a plurality of first alignment portions that cooperate with the cover to combine the cover and the upper cover. The rear side of the cover extends a plurality of second alignment portions that cooperate with the upper cover to combine the cover and the upper cover. The first alignment portions and the second alignment portions are offset from each other.

In an embodiment of the server of the present invention, the front and rear sides of the upper cover have a parallel front edge and a rear edge. The convex hull extends in a direction parallel to the front edge. The vertical distance from the convex hull to the front edge of the upper cover does not exceed one quarter of the vertical distance between the front edge and the rear edge of the upper cover.

In an embodiment of the server of the present invention, the two sides of the board are vertical The ground is set on the bottom plate.

Based on the above, the servo of the present invention redesigns the structure of the upper cover as compared with the conventional structure, so that the upper cover has a convex hull which is easy to mold and has a low manufacturing cost. As far as the upper cover of the server is concerned, the area between the two folded edges is usually large and the shape is relatively simple (usually a plane), which is insufficient in strength and prone to drumming, from the side where one of the folded edges is located The design of the convex hull on which the other side of the hem is extended (i.e., the convex hull extends substantially laterally rather than longitudinally) has been empirically proven to effectively increase the strength of the area between the two hem portions to overcome the drumming phenomenon. Accordingly, the upper cover does not have members that are riveted to each other, so that the upper cover is produced without deformation or bending of the stress caused by uneven stress distribution, and has good flatness. In this way, the convex hull can reduce the problem that the upper cover is not easily assembled due to deformation or bending of the upper cover. In addition, the server of the present invention and the upper cover of the casing are designed to add a convex hull to release a local force when the upper cover is made, thereby avoiding excessive stress concentration.

The above described features and advantages of the present invention will be more apparent from the following description.

1 is a schematic diagram of a server in accordance with an embodiment of the present invention. 2 is an exploded view of the server of FIG. 1. Figure 3 is a schematic view of the upper cover of Figure 1 separated from the bottom case. It should be noted that FIG. 2 and FIG. 3 omits part of the electronic components of the server for convenience of explanation.

Referring to FIG. 1 to FIG. 3, the server 100 of the embodiment includes a machine. The casing 110, a hard disk module 120, a motherboard module 130, and a fan module 140, wherein the casing 110 and the hard disk module 120 are assembled. The hard disk module 120 is located at the front end of the server 100.

The casing 110 includes a bottom casing 112 and an upper cover 114. The motherboard module 130 is disposed in the bottom case 112 as shown in FIG. 3 and is provided with a CPU, and the fan module 140 is disposed on a rear side of the bottom case 112. The motherboard module 130 is connected to the fan module 140. The fan module 140 of the present embodiment is adjacent to the hard disk module 120, so that the airflow provided by the fan module 140 can enter the hard disk module 120 to dissipate heat from the hard disk module 120.

In this embodiment, the bottom case 112 has a bottom plate 112a, two side plates 112b on opposite sides of the bottom plate 112a, a rear end 112c and a front end 112d. The two side plates 112b are vertically erected on the bottom plate 112a. Accordingly, the hard disk module 120 is adapted to be slid into the front end 112d of the bottom case 112 to be assembled to the bottom case 112. When the hard disk module 120 is slid in from the front end 112d of the bottom case 112 to be assembled to the bottom case 112, the hard disk frame 122 partially overlaps the two side plates 112b of the bottom case 112, wherein the back plate 124 is perpendicular to the bottom plate 112a. The upper cover 114 is parallel to the bottom plate 112a. Next, the upper cover 114 is slid into the bottom case 112 from the rear end 112c of the bottom case 112, and the assembly of the server 100 is completed.

4 is an enlarged schematic view of the lock of FIG. 2. For the convenience of description, FIG. 4 only shows a part of the upper cover. Referring to FIG. 3 to FIG. 4, the upper cover 114 of the embodiment further has a locking piece 114a. When the upper cover 114 is slid into and covered by the rear end 112c of the bottom case 112, the lock 114a is adapted to drive the upper cover 114 to move toward the hard disk frame 122 to fix the upper cover 114 to the bottom case 112. A guide pin 116 can be further disposed in the bottom case 112 to engage the lock The firmware 114a cooperates to achieve the positioning function.

For example, when the upper cover 114 is slid into and covered by the rear end 112c of the bottom case 112, the guide pin 116 is passed through the lock 114a. Then, the lock member 114a is pivoted from the position P1 shown in FIG. 4 to the position P2 shown in FIG. 1 with the guide pin 116 as a fulcrum. At the same time, the lock 114a moves the upper cover 114 toward the hard disk frame 122 to reach The function of closing the upper cover 114. The position of the guide pin 116 is not limited herein. For example, the guide pin 116 can be mounted on a fixing member (not shown) in the bottom case. However, the present invention can be applied to the present embodiment as long as the lock can push or pull the upper cover when the lock is rotated relative to the guide pin.

Figure 5 is a schematic illustration of another perspective of the upper cover of Figure 1. Referring to FIG. 5, in the embodiment, opposite sides of the upper cover 114 are provided with two folded edges 114f, 114g which abut against the corresponding side plates 112b. The upper cover 114 also has an elongated convex hull 114b. The convex hull 114b extends from a side where one of the hem 114f is located to a side where the other hem 114g is located and protrudes from the surface of the upper cover 114. Compared with the conventional structure, the servo 100 of the present invention redesigns the structure of the upper cover 114, so that the upper cover 114 has a convex hull 114b which is easy to mold and has a low manufacturing cost. As for the upper cover 114 of the server 100, the area between the two folded edges 114f and 114g is usually large and the shape is relatively simple (usually a plane), and the strength is insufficient and the drumming phenomenon is easy to occur. The design of the convex hull 114b where one side of the 114f extends to the side where the other hem 114g is located (ie, the convex hull 114b extends substantially laterally rather than longitudinally) has been empirically confirmed to effectively increase the gap between the two hem 114f, 114g The strength of the area to overcome the drumming phenomenon. Accordingly, the upper cover 114 does not have riveted joints. Since the member is formed, the upper cover 114 is formed without deformation or bending of the stress caused by uneven stress distribution, and has good flatness. In this way, the convex hull 114b can reduce the problem that the upper cover 114 is not easily assembled due to deformation or bending.

In addition, the upper cover 114 of the server 100 of the present invention releases the local force when the upper cover 114 is formed by adding the design of the convex cover 114b to avoid excessive stress concentration, thereby effectively enhancing the flatness of the upper cover 114.

Specifically, the convex hull 114b of the present embodiment is, for example, a rib or a rib structure to reinforce the structure of the upper cover 114. The projections of the backing plate 124 and the convex hull 114b in a direction perpendicular to the direction of the bottom plate 112a at least partially coincide, and the convex hull 114b extends in a direction parallel to the backing plate 124. When the upper cover 114 covers the bottom case 112, the convex cover 114b is located on the back plate 124, and the upper and lower ends of the back plate 124 are respectively located between the convex package 114b and the hard disk frame 122 to be protected by the convex package 114b. Further, the convex hull 114b of the embodiment can cooperate with the positioning of the guiding pin 116 and the locking piece 114a to achieve the function of the convex hull 114b on the backing plate 124. In addition, the frictional force of the contact portion between the convex hull 114b and the backing plate 124 can also serve as an auxiliary fixing manner.

In addition, we can determine the number, shape, and arrangement position of the convex hulls 114b by determining the actual configuration inside the backing plate 124. For example, if the convex hull 114b corresponds to the position of the back plate 124 with electronic components, the convex hull 114b can be designed to be suspended from the backing plate 124 to avoid the electronic components. Conversely, if the convex hull 114b has no electronic components corresponding to the position of the backing plate 124, the convex hull 114b may be designed to partially contact the backing plate 124 to provide more frictional force to assist the upper cover 114 to be fixed to the bottom casing 112. . Of course, in its In his embodiment, the convex hull may be disposed at other positions of the upper cover instead of the position corresponding to the backboard.

6 is a schematic diagram of another perspective of the server of FIG. 1. For convenience of explanation, only a part of the upper cover and the bottom case are drawn here. Referring to FIG. 2 and FIG. 6 , in the embodiment, the hard disk module 120 includes a hard disk frame 122 and a back plate 124 . The hard disk frame 122 further has a rear side 122a and a front side 122b parallel to the side plates 112b as shown in FIG. 2, wherein the back plate 124 is disposed on the rear side 122a of the hard disk frame 122 and perpendicular to the bottom plate 112a. The rear side 122a of the hard disk frame 122 is parallel to the side plates 112b, and the front side 122b of the hard disk frame 122 is parallel to the side plates 112b. The front side 122b of the hard disk frame 122 is formed with a plurality of hard disk insertion openings 122c.

The hard disk module 120 further includes a plurality of hard disks 128. The hard disks 128 are pluggably disposed in the hard disk frame 122 and electrically connected to the back plate 124. These hard disks 128 are adapted to be mounted to or detached from the hard disk shelf 122 via the hard disk insertion openings 122c. It should be noted that FIG. 6 illustrates that the three hard disks 128 are mounted on the hard disk frame 122 via the corresponding hard disk insertion opening 122c. However, the number of the hard disks 128 is merely an example, and the present invention does not limit the same. In addition, the hard disk frame 122 may have a guide frame (not shown) adapted to load the hard disk 128 from the hard disk insertion opening 122c to the hard disk frame 128.

It should be noted that this embodiment does not limit the manner in which the hard disk module 120 and the bottom case 112 are assembled. For example, it is possible to achieve a fixed function by snapping each other. Of course, in other embodiments, the hard disk module can also be fixed to the bottom case by means other than a buckle, that is, the manner in which the hard disk module is fixed to the bottom case is not limited to the above.

In this embodiment, the hard disk module 120 further has a cover 126. The front side of the upper cover 114 extends to define a plurality of first alignment portions 114c that cooperate with the cover plate 126 to combine the cover plate 126 with the upper cover 114. These first alignment portions 114c extend from one end of the upper cover 114. These first alignment portions 114c are parallel to the bottom plate 112a. On the other hand, the cover plate 126 is located on the front side of the upper cover 114 and combined with the upper cover 114 to assemble the cover plate 126 to the hard disk frame 122, and the convex cover 114b is located in the front side region of the upper cover 114. The rear side of the cover plate 126 extends to define a plurality of second alignment portions 126a that cooperate with the upper cover 114 to combine the cover plate 126 with the upper cover 114. These second alignment portions 126a extend from one end of the cover plate 126. These second alignment portions 126a are parallel to the bottom plate 112a. When the upper cover 114 is slid into and covered by the rear end 112c of the bottom case 112 as shown in FIG. 2, the first alignment portions 114c and the second alignment portions 126a are displaced from each other without interfering with each other.

In addition, the front and rear sides of the upper cover 114 have a parallel front edge 114e and a rear edge 114d. The convex hull 114b extends in a direction parallel to the front edge 114e. The first alignment portion 114c extends from the front edge 114e, and the vertical distance of the convex package 114b to the front edge 114e of the upper cover 114 does not exceed a quarter of the vertical distance between the front edge 114e and the rear edge 114d of the upper cover 114. Since the front edge 114e extends a plurality of first alignment portions 114c, and the front edge 114e is also an area where the cover plate 126 is assembled and matched, it is affected by more processing and assembly, and is easy to become a drumming stress. At the source, the convex hull 114b is disposed in a region closer to the front edge 114e to facilitate the barrier stress and more effectively suppress the drumming phenomenon.

In addition, we can use the actual configuration inside the server 100 to determine Determine the number, shape and arrangement position of the convex hulls 114b. For example, the convex hull can be configured above the motherboard module or the fan module in the server to increase the strength of the upper cover.

In the above embodiments, the convex hull may have only a single rib. In other embodiments, the convex hull may have other forms, and is not limited to the above, as long as it is extended from the upper cover and is opposite to the back plate. Cooperating convex hulls are within the scope of the invention. Of course, the shape is a straight stripe as an illustration, and the invention is not limited thereto.

In summary, the servo of the present invention redesigns the structure of the upper cover compared to the conventional structure, so that the upper cover has a convex hull which is easy to form and has a low manufacturing cost. In the upper cover of the servo, the area between the two folded edges is usually large and the shape is relatively simple (usually a plane), which is insufficient in strength and prone to drumming, from the side where one of the folded edges is to the other The design of the convex hull on which one side of the hem extends (ie, the convex hull extends substantially laterally rather than longitudinally) is verified to effectively increase the strength of the region between the two hem portions and overcome the drumming phenomenon. Accordingly, the upper cover does not have members that are riveted to each other, so that the upper cover is produced without deformation or bending of the stress caused by uneven stress distribution, and has good flatness. In this way, the convex hull can reduce the problem that the upper cover is not easily assembled due to deformation or bending of the upper cover. In addition, the server and the casing of the present invention release the local force when the upper cover is made by adding a reinforcing member to avoid excessive stress concentration, thereby effectively enhancing the flatness of the upper cover.

Although the present invention has been disclosed in the above embodiments, it is not intended to limit the present invention, and any one of ordinary skill in the art does not deviate. In the spirit and scope of the present invention, the scope of protection of the present invention is defined by the scope of the appended claims.
