Description

Technical Field

[0001] This utility model relates to the field of server equipment, specifically to a power supply module for a server. Background Technology

[0002] A server, also known as a servo server, is a device that provides computing services. It is a type of computer that provides computing or application services to other client machines (such as PCs, smartphones, ATMs, etc.) on a network. Because servers need to respond to and process service requests, they must have the capacity to undertake and guarantee services. Compared to general computer architectures, servers have higher requirements in terms of processing power, stability, reliability, security, scalability, and manageability. Currently, the power supply of a server is usually fixed inside the server chassis. When maintenance is required, the server must first be powered off, and other functional modules must be disassembled before the power supply can be repaired. Therefore, operation is inconvenient and maintenance efficiency is low.

[0003] In the prior art, power redundancy is a common practice. For example, the published US patent document US20240397677A1 describes a power supply device that uses at least two power supply units (such as closed power supplies) connected in parallel or other ways and is configured with a current sharing controller to achieve redundant power supply and load balancing; when one of the power supply units fails, hot-swappable replacement is supported.

[0004] However, existing redundant power supply solutions still have mechanical shortcomings. To achieve redundancy, multiple power supply units are typically fixedly installed inside the server chassis. These are usually secured with screws or directly inserted into a backplane interface with locking clips. When maintenance or replacement of a particular power supply unit is required, it is often necessary to first shut down the server and then use tools to disassemble it. This process is cumbersome due to limited space and complicated procedures, resulting in low maintenance efficiency and impacting the server's maintainability. Summary of the Invention

[0005] To address the above issues, this invention provides a redundant server power supply module.

[0006] The technical solution of this utility model is implemented as follows:

[0007] This utility model discloses a redundant server power supply module, installed inside a server chassis, comprising: an outer cover and a power supply unit; the outer cover includes: a top wall, and two side walls extending downward from both sides of the top wall, the top wall and the two side walls forming a U-shaped structure; multiple power supply units are sequentially arranged within the U-shaped structure, each power supply unit including: a power housing and an elastic fixing member, the elastic fixing member being installed inside the power housing; wherein, a spring piece extending outward from an opening on the top plate of the power housing abuts against the top wall of the outer cover, for fixing the power supply unit inside the outer cover.

[0008] As a further limitation of this utility model, a first elastic sheet is provided on the outer side of one side wall of the power supply housing, and a second elastic sheet is provided on the inner side of the other side wall of the power supply housing. Both the first elastic sheet and the second elastic sheet can elastically deform along the horizontal direction of the power supply housing.

[0009] Preferably, one end of the first elastic piece is fixedly connected to the outer surface of the side wall of the power supply housing, and the other end of the first elastic piece extends toward the front panel of the power supply housing to form the first handle of the first elastic piece.

[0010] Preferably, one end of the second elastic piece is fixedly connected to the inner surface of the other side wall of the power supply housing, and the other end of the second elastic piece extends out from the front panel of the power supply housing to form the second handle of the second elastic piece.

[0011] Preferably, the front end of one side wall of the outer cover extends outward and bends backward to form a wing plate, which is used to fasten and connect with the side plate of the server chassis to fix the power supply module inside the server chassis.

[0012] Preferably, the power supply units are detachably connected to each other and to the outer casing.

[0013] The redundant server power supply module of this utility model has the following beneficial technical effects:

[0014] The server power supply module of this utility model uses multiple power supply units, each of which is powered independently and is detachable. Therefore, when repairing the power supply, the damaged power supply unit can be pulled out from the back of the server chassis for maintenance without interrupting the power supply to the server. As a result, the operation is very convenient and efficient. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 A redundant server power supply module is installed inside a server chassis 1 for powering the server. The power supply module includes an outer casing 2 and power supply units 3. The outer casing 2 includes a top wall 11 and two side walls 12 extending downwards from both sides of the top wall 11, forming a U-shaped structure. Four power supply units 3 are arranged sequentially within the U-shaped structure. Each power supply unit 3 includes a power housing 31 and an elastic fixing member 32. The power housing 31 is approximately square in shape. Figure 7 As shown, the main body of the elastic fastener 32 is installed inside the power supply housing 31. The arc-shaped spring piece 321 of the elastic fastener 32 extends outward from the opening on the top plate of the power supply housing 31 and abuts against the top wall 11 of the outer cover 2 to fix the power supply unit 3 inside the outer cover 2.

[0027] like Figure 5 and Figure 6 As shown, a first elastic piece 33 is provided on the outer side of one side wall of the power supply housing 31, and a second elastic piece 34 is provided on the inner side of the other side wall of the power supply housing 32. Both the first elastic piece 33 and the second elastic piece 34 can move elastically along the horizontal direction of the power supply housing 31. During installation, the four power supply units 3 are located between the two side walls 12 of the outer cover 2. The first elastic piece 33 and the second elastic piece 34 on each power supply unit 3 exert an elastic force in the horizontal direction, so that the four power supply units 3 are fixed to the outer cover 2.

[0028] like Figure 5 , Figure 6 and Figure 8 As shown, one end of the first elastic piece 33 is fixedly connected to the outer surface of the side wall of the power supply housing 31, and the other end of the first elastic piece 33 extends toward the front panel of the power supply housing 31 and extends beyond its front panel, forming the first handle 331 of the first elastic piece 33. One end of the second elastic piece 34 is fixedly connected to the inner surface of the other side wall of the power supply housing 31, and the other end of the second elastic piece 34 extends out from the front panel of the power supply housing 31, forming the second handle 341 of the second elastic piece 34. When the power supply unit 3 needs to be removed from the server chassis 1, the first handle 331 of the first elastic piece 33 and the second handle 341 of the second elastic piece 34 are pressed inward, the first elastic piece 33 and the second elastic piece 34 are deformed by force, and a gap is generated on both sides of the power supply unit 3. Then, the power supply unit 3 can be pulled out from the server chassis 1. At the same time as the power supply unit 3 is pulled out, the elastic piece 321 of the elastic fixing member 32 is subjected to the force of the top wall 11 of the outer cover 2 and undergoes elastic deformation.

[0029] like Figure 1 , Figure 2 and Figure 4 As shown, the front end of one side wall of the outer cover 2 extends outward and bends backward to form a wing plate 13. The side wall of the outer cover 2 has a slot, and the wing plate 13 is fastened to the side plate of the server chassis 1 through the slot to fix the power supply module inside the server chassis 1.

[0030] It should be noted that in the power module of this embodiment, the multiple power units 3 are detachable due to the elastic force of the elastic element between the power units 3 and between the power units 3 and the outer cover 2.

[0031] The server power supply module of this utility model uses multiple power supply units, each of which is powered independently and can be detached and installed. Therefore, when repairing a single power supply unit, the damaged power supply unit can be pulled out from the back of the server chassis for maintenance without interrupting the power supply to the server. Thus, the operation is very convenient and efficient.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
