AI Technical Summary
[0003]传统的电源壳体是采用回字形单侧封口的结构，然后开口侧的四边向中部弯折形成与盖板进行配合的装配部，然后将风扇固定在盖板上，这种设计由于装配部向内弯折，导致回字形壳体中供于风扇安装的空间变小，从而使得能够使用的风扇规格较小，这使得需要更大尺寸的风扇则需要增大壳体尺寸，为此特提供一种兼容多规格风扇安装的电源壳体
该兼容多规格风扇安装的电源壳体，通过将两个壳体均设置为C形，安装时相对错位放置，并且第一罩壳的两个侧壁向中部弯折90°形成安装部，安装部与第二罩壳的两个侧壁进行固定，从而在安装过程中使得安装部能够与设置在第二罩壳端面上的风扇安装工位避开，以使得安装部与其相连的两个侧壁之间合围形成装配空间能够成为最大的风扇装配空腔，以此满足不同规格的风扇进行安装，避免因为安装部阻挡影响风扇安装。

Description
Technical Field
[0001] This utility model relates to the field of power supply housing technology, specifically to a power supply housing compatible with the installation of fans of various specifications. Background Technology
[0002] Nowadays, most computer power supplies use an independent assembly structure, with internal modules encapsulated in a casing. These internal modules generate a lot of heat during use, so a fan needs to be installed on the casing to ensure safe operation.
[0003] Traditional power supply housings use a U-shaped, single-sided sealed structure. The four sides of the open side are bent towards the center to form an assembly that fits with a cover plate. The fan is then fixed to the cover plate. This design, due to the inward bending of the assembly, reduces the space available for fan installation within the U-shaped housing, resulting in smaller fan sizes that can be used. This necessitates increasing the housing size for larger fans. Therefore, a power supply housing compatible with multiple fan sizes is provided. Utility Model Content
[0004] To overcome the shortcomings of the prior art, this utility model proposes a power supply housing compatible with the installation of multiple fan specifications, including two housings, both of which are C-shaped, so that each housing has an end face and two side walls perpendicular to the end face, and a clearance portion is formed between the two side walls. The two housings are arranged in a staggered manner, so that the side walls of the two housings are respectively inserted into the clearance portion on their side, and the end faces of the two housings are parallel to each other. A set of side walls of the housing are bent toward the center at ° to form a mounting part, and the mounting part and the two side walls connected to it enclose an assembly space; Another set of the housings has a fan mounting station on its end face. The mounting part avoids the fan mounting station, so that the size of the fan installed at the fan mounting station is not greater than the cross-sectional size of the assembly space.
[0005] Preferably, the housing includes a first cover and a second cover, wherein the first cover and the second cover are respectively formed by stamping from a single piece of metal sheet.
[0006] Preferably, the mounting part is disposed on the first cover, and the fan mounting station is located on the second cover.
[0007] Preferably, the top of the mounting part is punched to form a snap-fit groove, and the two side walls of the second cover are punched to form protrusions, which are movably snapped into the snap-fit groove.
[0008] Preferably, the two ends of the second cover are bent into the clearance portion to form a limiting portion, and the tops of the two side walls of the first cover are recessed into the middle to form a limiting groove for insertion into the limiting portion.
[0009] Preferably, the mounting part is provided with a fixing screw hole, and the two side walls of the second cover are provided with mating holes that are directly opposite the fixing screw hole.
[0010] Preferably, the bottom ends of the two side walls of the second cover are bent inward to form an insertion positioning part, and the two sides of the end face of the first cover are bent into the clearance part to form a blocking part, and the insertion positioning part is movably inserted into the inner side of the blocking part.
[0011] Preferably, the blocking part is attached to the outer wall of the mounting part, and the two are fixedly welded together.
[0012] Preferably, the two sides of the insertion positioning part are punched to form gaps to avoid the mounting part.
[0013] Preferably, the side of a set of mounting parts is punched to form a separation part between the top edge of the mounting part and the side wall of the first cover, and the separation part is formed into a concave grounding connection position by inward punching.
[0014] Preferably, the end face of the first cover is integrally formed with a PCB fixing position, and an air inlet and a component assembly hole are provided on one side wall of the first cover, with the air inlet avoiding the component assembly hole; a PCB terminal avoidance station is provided on the other side wall of the first cover.
[0015] In summary, this power supply housing compatible with multiple fan sizes offers the following advantages: This power supply housing, compatible with multiple fan sizes, features two C-shaped housings that are staggered during installation. The two side walls of the first housing are bent 90° towards the center to form a mounting section, which is then fixed to the two side walls of the second housing. This design allows the mounting section to avoid the fan mounting position on the end face of the second housing during installation, maximizing the assembly space between the mounting section and its two connected side walls. This design accommodates fans of different sizes and prevents the mounting section from obstructing the fan installation process.
[0016] This power supply housing, compatible with multiple fan sizes, features a snap-fit groove on the mounting section and protrusions formed by punching on the two side walls of the second housing. These protrusions engage with the snap-fit groove, while the end face of the second housing inserts into the limiting groove of the first housing via a limiting part. The insertion positioning part of the second housing inserts into the blocking part of the first housing, thus achieving multi-point insertion positioning. This prevents gaps from forming between the two housings due to housing deformation during use, reduces the use of assembly screws, and makes disassembly and assembly more convenient.

[0021] like Figure 1-3 As shown, the preferred embodiment of this utility model provides a power supply housing compatible with multiple fan sizes, comprising two housings, both of which are C-shaped, such that each housing has an end face and two side walls perpendicular to the end face, with clearance portions formed between the two side walls, and the two housings are staggered relative to each other, such that the side walls of the two housings are respectively inserted into the clearance portions on their sides, and the end faces of the two housings are parallel to each other. A set of housing side walls bend 90° towards the middle on both sides to form a mounting part 17, and the mounting part 17 and the two side walls connected to it enclose an assembly space; Another set of housings has a fan mounting station 22 on its end face. The mounting part 17 avoids the fan mounting station 22, so that the size of the fan installed at the fan mounting station 22 is not greater than the cross-sectional size of the assembly space.
[0022] The housing includes a first cover 1 and a second cover 2, which are respectively formed by stamping from a single piece of metal sheet.
[0023] The mounting section 17 is located on the first housing 1, and the fan mounting station 22 is located on the second housing 2.
[0024] The top of the mounting part 17 is punched to form a snap-fit groove 18, and the two side walls of the second cover 2 are punched to form protrusions 27, which are movably snapped into the snap-fit groove 18.
[0025] The end face of the second cover 2 is bent towards the clearance portion to form a limiting portion 23, and the top of the two side walls of the first cover 1 is recessed towards the center to form a limiting groove 111 for insertion into the limiting portion 23.
[0026] The mounting part 17 has a fixing screw hole 19, and the two side walls of the second cover 2 each have a mating hole 26 that is directly opposite the fixing screw hole 19.
[0027] The bottom ends of the two side walls of the second cover 2 are bent inward to form the insertion positioning part 24, and the two sides of the end face of the first cover 1 are bent into the clearance part to form the blocking part 15.
