[0036] The present application provides a server chassis, which is scalable and can reduce the waste of original chassis resources when upgrading and renovating equipment.

[0037] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0038] See also Figure 1 to Figure 6 The embodiment of the present application provides a server chassis, including a bottom shell 2, an upper cover 1 and a side panel 3, wherein the bottom shell 2 has a rectangular bottom surface 21 and side walls 22 arranged on both sides along the length direction of the bottom surface 21, and the side walls 22 have a first connection portion. The upper cover 1 has a rectangular top surface 11 and side edges 12 arranged on both sides along the length direction of the top surface 11, and the side edges 12 have a second connection portion. The side panel 3 is rectangular as a whole, and its length corresponds to the side wall 22 of the bottom shell 2 and the side edge 12 of the upper cover 1. The side panel 3 has a first edge 31 at the lower side and a second edge 32 at the upper side of the side panel 3. The first edge 31 is provided with a third connection portion that can be detachably connected to the first connection portion, and the second edge 32 is provided with a fourth connection portion that can be detachably connected to the second connection portion. The bottom shell 2, the side panels 3 and the upper cover 1 are sequentially arranged along the height direction (or thickness direction) of the server chassis, the bottom surface 21 of the bottom shell 2 constitutes the bottom of the server chassis, the top surface 11 of the upper cover 1 constitutes the top of the server chassis, and the side panels 3 are arranged in pairs on both sides of the server chassis to constitute part of the side surface of the server chassis. The detachable connection between the bottom shell 2 and the side panels 3, and the detachable connection between the upper cover 1 and the side panels 3, allow the bottom shell 2, the side panels 3 and the upper cover 1 to be reused when the equipment is upgraded and renovated, thereby reducing the waste of the original chassis resources.

[0039] In a preferred embodiment, the first connection part has the same structure as the fourth connection part, and the second connection part has the same structure as the third connection part, that is, the side wall 22 of the bottom shell 2 and the second side 32 (i.e., the upper side) of the side panel 3 have a connection part with the same structural form, and the side edge 12 of the upper cover 1 and the first side 31 (i.e., the lower side) of the side panel 3 have a connection part with the same structural form. With such an arrangement, after the side panel 3 is removed from the server chassis, the upper cover 1 and the bottom shell 2 can be directly detachably connected, thereby forming a server chassis of a new specification, that is, the upper cover 1 and the bottom shell 2 can be detachably connected through the connection between the first connection part and the second connection part. Figure 1As shown, in this embodiment, the upper cover 1 and the bottom shell 2 are directly detachably connected to form a 1U server 100, and by adding the side panel 3, it is expanded to a 2U server 200. It is easy to understand that on the basis of the 2U server 200, by adding the side panel 3, it can be expanded to a server with a higher height, such as a 4U server or an 8U server. In other embodiments, in order to realize that the upper cover 1 and the bottom shell 2 can be directly detachably connected, a special connection part can also be set up separately, instead of being realized by the connection between the first connection part and the second connection part. For example, the side wall 22 has a fifth connection part, and the side 12 has a sixth connection part that can be detachably connected to the fifth connection part. In this structure, the first connection part and the fourth connection part can be set to have different structures, and the second connection part and the third connection part can be set to have different structures. However, when the upper cover 1 and the bottom shell 2 are connected through the side panel 3, the fifth connection part and the sixth connection part are not used, that is, they are in an idle state. It is easy to understand that by setting the first connection part and the fourth connection part to have the same structure, and the second connection part and the third connection part to have the same structure, it is unnecessary to set up a special connection part on the upper cover 1 and the bottom shell 2 for directly connecting the upper cover 1 and the bottom shell 2, so that the structure of the server chassis is simpler, which is conducive to reducing the production cost.

[0040] like Figure 1 As shown, in this embodiment, adding a pair of side panels 3 can expand the 1U server 100 into a 2U server 200, that is, the width of the side panel 3 corresponds to the 1U height. In other embodiments, the width of the side panel 3 can also be set to correspond to other heights. For example, adding a pair of side panels 3 can expand the 2U server 200 into a 4U server. In this structure, the width of the side panel 3 corresponds to the 2U height.

[0041] In a preferred embodiment, the server chassis includes an expansion board formed by connecting at least two side panels 3, and two adjacent side panels 3 in the expansion board are connected by a third connection portion of one of them and a fourth connection portion of the other to be detachably connected. By setting an expansion board formed by connecting at least two side panels 3, a variety of servers of different specifications can be expanded more flexibly, thereby meeting the more diverse needs of users. Specifically, the expansion board can be formed by connecting side panels 3 of a single specification, that is, the specifications of each side panel 3 in the expansion board are the same, and the expansion board can also be formed by connecting side panels 3 of different specifications, that is, the expansion board includes a first side panel 3 and a second side panel 3 of different specifications. It should be noted that the different specifications of the first side panel 3 and the second side panel 3 refer to that the height increased by installing the first side panel 3 to the server chassis is different from the height increased by installing the second side panel 3. For example, installing the first side panel 3 increases the height of the server chassis by 1U, while installing the second side panel 3 increases the height of the server chassis by 2U.

[0042] See also Figure 6In a preferred embodiment, the server chassis includes a tray 4 for installing a power backplane, and a side panel 3 facing the inside of the chassis is provided with a rib or groove for engaging with the edge of the tray 4. When upgrading the equipment, for example, when expanding from a 1U server 100 to a 2U server 200, a larger storage space is formed inside the server chassis. By providing the tray 4, the storage space in the server chassis can be reasonably allocated, and a position can be provided for the installation of the power backplane. Specifically, the edge of the tray 4 is connected to the inner surface of the side panel 3, and the tray 4 is parallel to the top surface 11 of the upper cover 1 and the bottom surface 21 of the bottom shell 2. Part of the storage space of the server chassis can be divided into two upper and lower spaces by the tray 4. Providing ribs or grooves on the inner surface of the side panel 3 helps to improve the work efficiency of installing the tray 4. For example, Figure 6 In the steps of installing the tray 4 shown, the tray 4 is moved from top to bottom and placed between two opposite side panels 3. The edge of the tray 4 is snapped into the ribs or grooves on the inner surface of the side panels 3 to achieve quick positioning. On this basis, the connection between the tray 4 and the side panels 3 can be strengthened by fasteners such as bolts. Of course, if the ribs or grooves of the side panels 3 can provide sufficient supporting force, the tray 4 and the side panels 3 can also be connected only by snapping.

[0043] In a preferred embodiment, the server chassis includes a rear wall panel 5 which is rectangular as a whole, the upper edge of the rear wall panel 5 is connected to the upper cover 1, the lower edge of the rear wall panel 5 is connected to the bottom shell 2, and a fan module 6 for heat dissipation is installed on the side of the rear wall panel 5 facing the inside of the chassis. The rear wall panel 5 is located at the rear end of the server chassis, that is, the other end opposite to the entrance of the server chassis. The specifications of the rear wall panel 5 are selected according to the height of the server to be expanded, that is, there are a variety of rear wall panels 5 of different specifications for selection, and the size of the rear wall panel 5 in the height direction of the server chassis corresponds to an integral multiple of 1U. When it is necessary to expand to an nU server (n is a positive integer), the rear wall panel 5 corresponding to the height of nU is selected. The fan module 6 is installed on the rear wall panel 5, and the two can form a rear wall module, that is, when the rear wall panel 5 is replaced, the fan module 6 is replaced together. Of course, rear wall panels 5 of different specifications can also be provided with the same connection portion for installing the fan module 6, so that when the rear wall panel 5 is replaced, the fan module 6 does not need to be replaced, but the fan module 6 can be installed on the new rear wall panel 5. The number of fans in the fan module 6 can be one or more, for example, one fan module 6 includes four fans.

[0044] like Figure 4As shown, the first side 31 of the side panel 3 is provided with a third connection portion for connecting to the other side panel 3 below or the bottom shell 2, and the second side 32 of the side panel 3 is provided with a fourth connection portion for connecting to the other side panel 3 above or the upper cover 1. In specific practical applications, there are multiple options for the structural form of the connection portion. In a preferred embodiment, the fourth connection portion includes an L-shaped notch 33 opened on the edge of the side panel 3, and the third connection portion includes a limiting column 13 for clamping, and the axial direction of the limiting column 13 meets the vertical condition with the plate surface of the side panel 3. When two different side panels 3 are connected, the limiting column 13 of one side panel 3 slides into the notch 33 of the other side panel 3. See. Figure 7 , in order to illustrate the connection structure between the limiting column 13 and the L-shaped notch 33, Figure 7 The second connection part of the upper cover 1 and the third connection part of the side panel 3 have the same structure as each other. The second connection part of the upper cover 1 has a limit column 13 for clamping. When the upper cover 1 and the side panel 3 are assembled, the limit column 13 enters the notch 33 of the side panel 3 and slides to the end of the notch 33 along the L-shaped trajectory. The limit column 13 and the inner wall of the notch 33 form a clamping connection to limit the upper cover 1 from moving upward relative to the side panel 3.

[0045] In a preferred embodiment, the fourth connection portion includes a first mounting hole, and the third connection portion includes a second mounting hole corresponding to the position of the first mounting hole. When two different side panels 3 are connected, the first mounting hole of one side panel 3 is aligned with the second mounting hole of the other side panel 3 to form a bolt mounting hole. The detachable connection between the two side panels 3 can be conveniently and quickly achieved by bolts. Further preferably, as Figure 8 As shown, the nut 34 can be pre-fixedly connected to the body of the side panel 3, so that the trouble of finding the nut 34 can be saved during assembly, which is conducive to improving assembly efficiency. For example, the nut 34 is welded to the body of the side panel 3. Specifically, the nut 34 can be set at the first mounting hole as a part of the fourth connecting part, and can also be set at the second mounting hole as a part of the third connecting part.

[0046] It should be noted that the first mounting hole and the second mounting hole can be set as an open hole with a notch, or can be set as a closed hole without a notch. On the basis that the nut 34 is fixedly connected to the body of the side panel 3 in advance, a screw 35 inseparable from the nut 34 can be set, that is, the screw 35 is always connected to the nut 34, so that the trouble of finding the screw 35 can be saved during assembly, which is conducive to further improving the assembly efficiency. Taking the nut 34 fixed at the first mounting hole as an example, the second mounting hole is set as an open hole with a notch, the size of the notch is larger than the diameter of the screw 35, that is, the screw 35 can enter the second mounting hole from the notch. When assembling, first loosen the screw 35, and then tighten the screw 35 after the second mounting hole is aligned with the first mounting hole, thereby realizing the assembly of the two side panels 3.

[0047] In order to improve the connection strength between the side panels 3, in a preferred embodiment, the third connection portion includes a lock pin that is movably connected to the body of the side panel 3, and the fourth connection portion includes a lock hole, the axis of the lock hole and the width direction of the side panel 3 meet the parallel condition, and when two different side panels 3 are connected, the lock pin of one side panel 3 is inserted into the lock hole of the other side panel 3. It is easy to understand that after the lock pin is inserted into the lock hole, the relative movement of the two connected side panels 3 in the direction perpendicular to the axis of the lock hole can be restricted, thereby facilitating the improvement of the connection strength between the side panels 3. Specifically, in order to achieve the movable connection between the lock pin and the body of the side panel 3, the lock pin can be set to be slidably connected to the body of the side panel 3, for example, the lock pin is set to slide relative to the body of the side panel 3 along the width direction of the side panel 3. The lock pin can also be set to be rotatably connected to the body of the side panel 3, for example, the lock pin is set to be L-shaped, one end of which is hinged to the body of the side panel 3, and the other end is used to be plugged into the lock hole.

[0048] In order to improve the connection strength between the side panel 3 and the bottom shell 2, in a preferred embodiment, the first connection portion includes a plate-shaped support leg extending in the height direction of the chassis, and the third connection portion includes a slot for accommodating the support leg. When assembling the side panel 3 and the bottom shell 2, align the slot of the third connection portion of the side panel 3 with the support leg of the first connection portion of the bottom shell 2, and then move the side panel 3 from top to bottom onto the bottom shell 2 so that the support leg is inserted into the slot. It is easy to understand that after the support leg is inserted into the slot, the relative movement of the side panel 3 and the side wall 22 of the bottom shell 2 in a direction perpendicular to the height direction of the chassis can be restricted, thereby facilitating the improvement of the connection strength between the side panels 3. In other embodiments, the support leg of the first connection portion can also be set to be columnar, and the position of the support leg can also be changed from the side wall 22 to the bottom surface 21 of the bottom shell 2.

[0049] See also Figure 7 and Fig. 9 In the scenario where the side panel 3 or the upper cover 1 is connected to the lower side panel 3 or the bottom shell 2 by moving along the L-shaped track, if the side panel 3 or the bottom shell 2 is provided with a columnar support extending in the height direction of the chassis, it will be difficult to assemble the side panel 3 or the upper cover 1 with a conventional slot structure. For this reason, the side panel 3 or the upper cover 1 can be provided with a slot structure such as Fig. 9 The spring sheet 36 shown in the figure has a card interface 361 at its movable end. When the side panel 3 or the upper cover 1 moves along the L-shaped track, it first moves along the height direction of the chassis so that the card interface 361 of the spring sheet 36 reaches the same height position as the columnar support foot, and then moves in a direction perpendicular to the height direction of the chassis so that the spring sheet 36 meets the columnar support foot. After the meeting, the spring sheet 36 continues to move and will be deformed under the squeezing action of the support foot, for example Fig. 9The spring piece 36 in the middle moves away from the inner surface of the side plate 3. When the side plate 3 or the upper cover 1 moves along the L-shaped track, the snap-in interface 361 of the spring piece 36 reaches the position where the support leg is located. At this time, the spring piece 36 restores its shape and the snap-in interface 361 is buckled onto the support leg to form a snap connection. Fig. 9 As shown, in order to make the spring sheet 36 easily deformed under the squeezing action of the support foot, an inclined sliding guide surface can be set on the outer side of the card interface 361. When the spring sheet 36 meets the support foot, the sliding guide surface contacts the support foot, which can make the spring sheet 36 more easily squeezed by the support foot to the desired deformation direction.

[0050] In this specification, each part of the structure is described in a progressive manner, and the structure of each part focuses on the differences from the existing structure. The overall and partial structures of the server chassis can be obtained by combining the structures of the above multiple parts.

[0051] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
