[0002] A computer power supply is a device that provides stable and reliable power to components such as the motherboard, graphics card, and hard drive of a computer host. The computer power supply is assembled by forming an enclosed space through the computer power supply casing to house the main circuitry and cooling fan.

[0003] Existing computer power supply cases are generally modular structures. During assembly, multiple screws and other fasteners are needed to connect and fix the various surfaces of the case components, and multiple fasteners are also needed to fix the cooling fan to the case components. Disassembling and assembling this type of computer power supply case takes a lot of time. After a period of use, the airflow driven by the cooling fan will bring in dust from the air. The accumulation of dust on the cooling fan will affect the normal cooling efficiency and thus affect the operation of the computer power supply. Therefore, it is necessary to disassemble the computer power supply case for cleaning every once in a while. The excessive number of fasteners makes the computer power supply case difficult to disassemble and assemble, and each cleaning process takes a lot of time, affecting the user experience. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a computer power supply housing that is easy to disassemble and assemble, so as to solve the above problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] This utility model provides a computer power supply housing that is easy to disassemble and assemble, which includes an upper housing, a lower housing, and a fan mounting frame.

[0007] The upper housing includes an upper cover plate and two upper side plates connected to the front and rear sides of the upper cover plate, respectively. The upper cover plate has an upper housing connection hole. The lower housing includes a lower bottom plate and two lower side plates connected to the left and right sides of the lower bottom plate, respectively. The top ends of the two lower side plates extend towards each other to form inwardly folded connecting strips. The inwardly folded connecting strips have positioning grooves, and the positioning grooves have lower housing connection holes. The fan mounting frame includes a support plate, a positioning baffle connected to the rear side of the support plate, and two connecting vertical plates connected to the left and right sides of the support plate, respectively. The support plate has a fan mounting hole for locking a cooling fan placed on the support plate with screws. The top ends of the connecting vertical plates extend outward to form connecting pieces, and the connecting pieces have frame connection holes. The connecting pieces are placed in the positioning grooves, and screws are sequentially passed through the upper housing connection hole, frame connection hole, and lower housing connection hole. The upper housing and lower housing are mated and locked together. The upper and lower side plates surround the fan mounting frame, and the fan mounting frame is locked to the inwardly folded connecting strips.

[0008] Preferably, the top of the upper shell cover is provided with a fan air inlet, and the support plate is provided with an airflow channel corresponding to the fan air inlet. The upper shell cover has four upper shell connecting holes, which are arranged around the fan air inlet. Each connecting vertical plate has two connecting pieces, which are located at the front and rear ends of the connecting vertical plate respectively.

[0009] Preferably, fan frame fixing strips are connected to the opposite surfaces of the two connecting vertical plates. The fan frame fixing strips extend toward the positioning baffle. When the cooling fan is placed on the support plate, the fan frame fixing strips can be inserted into the slots opened on both sides of the cooling fan, and the two fan frame fixing strips clamp and fix the two sides of the cooling fan.

[0010] Preferably, the fan frame fixing strip is an elastic material strip, which is suspended above the support plate and forms a gap with the support plate.

[0011] Preferably, the thickness of the fan frame fixing strip gradually decreases at the front end away from the positioning baffle, forming an inclined surface that guides the two sides of the cooling fan to connect.

[0012] Preferably, the bottom plate of the lower shell extends upward to form bottom edge seals on the front and rear sides, the side plates of the lower shell extend upward to form side edge seals on the front and rear sides, and the side plates of the upper shell overlap the side edge seals and are sandwiched between the side edge seals and the bottom edge seals.

[0013] Preferably, the top surface of the connecting piece is flush with the top surface of the inward-turning connecting strip, and the upper shell cover is attached to the connecting piece to press the connecting piece against the positioning groove.

[0014] The technical effects achieved by this utility model include:

[0015] In the aforementioned computer power supply housing, a positioning groove is formed on the inward-folding connecting strip of the lower housing, and the lower housing connection hole is opened in the positioning groove. A fan mounting frame is set to install the cooling fan. The connecting piece of the fan mounting frame has a frame connection hole corresponding to the lower housing connection hole. By placing the connecting piece into the positioning groove, the fan mounting frame rests on the inward-folding connecting strip. By simply passing screws through the upper housing connection hole, frame connection hole, and lower housing connection hole in sequence, the upper housing and lower housing are docked and locked together, and the fan mounting frame is locked on the inward-folding connecting strip. The upper housing, lower housing, and fan mounting frame can be quickly assembled or separated. The fan mounting frame can be removed to clean the cooling fan by unscrewing the screws. It takes less time and provides a good user experience.

[0016] By connecting fan frame fixing strips to two connecting vertical plates, the fan frame fixing strips can be inserted into the slots opened on both sides of the cooling fan. The two fan frame fixing strips clamp and fix the two sides of the cooling fan, which can reduce the number of fan mounting holes and further simplify disassembly and assembly.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Examples of these preferred embodiments are illustrated in the drawings. The embodiments of this utility model shown in and described with reference to the drawings are merely exemplary, and this utility model is not limited to these embodiments.

[0028] It should also be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the solution according to the present invention are shown in the accompanying drawings, while other details that are not closely related are omitted.

[0029] like Figure 1 and Figure 2 As shown, this utility model embodiment provides a computer power supply housing that is easy to disassemble and assemble, which includes an upper housing 1, a lower housing 2, and a fan mounting frame 3.

[0030] The upper shell 1 includes an upper shell cover plate 11 and two upper shell side plates 12 respectively connected to the front and rear sides of the upper shell cover plate 11. The upper shell cover plate 11 is provided with an upper shell connection hole 110a.

[0031] The lower shell 2 includes a lower shell bottom plate 21 and two lower shell side plates 22 respectively connected to the left and right sides of the lower shell bottom plate 21. The top ends of the two lower shell side plates 22 extend towards each other and form inwardly turned connecting strips 221, which are combined with Figure 2 and Figure 3 As shown, the inward-turning connecting strip 221 is provided with a positioning groove 220a, and a lower shell connecting hole 220b is opened in the positioning groove 220a;

[0032] Combination Figure 4 and Figure 5 As shown, the fan mounting frame 3 includes a support plate 31, a positioning baffle 32 connected to the rear side of the support plate 31, and two connecting vertical plates 33 respectively connected to the left and right sides of the support plate 31. The support plate 31 has a fan mounting hole 310a for locking the cooling fan 4 placed on the support plate 31 with screws. The positioning baffle 32 is used to abut against the cooling fan 4 to quickly position the cooling fan 4 in the front and rear positions on the support plate 31. Pushing the cooling fan 4 into the positioning baffle 32 will allow the hole of the cooling fan 4 to be quickly aligned with the fan mounting hole 310a. The top of the connecting vertical plate 33 extends outward to form a connecting piece 331, and the connecting piece 331 has a frame connecting hole 330.

[0033] The connecting piece 331 is placed into the positioning groove 220a so that the fan mounting frame 3 rests on the inward connecting strip 221. The upper shell connecting hole 110a, the frame connecting hole 330 and the lower shell connecting hole 220b are sequentially passed through the screws. The upper shell 1 and the lower shell 2 are docked and locked. The upper shell side plate 12 and the lower shell side plate 22 surround the fan mounting frame 3, and the fan mounting frame 3 is locked on the inward connecting strip 221.

[0034] Therefore, by using screws passing through the upper shell connection hole 110a, the frame connection hole 330, and the lower shell connection hole 220b, the upper shell 1, the lower shell 2, and the fan mounting frame 3 are simultaneously locked together. When disassembling the computer power supply casing to clean the internally installed cooling fan 4, simply unscrew the aforementioned screws. Figure 5 As shown, after removing the upper housing 1, the fan mounting frame 3, which rests on the inward-folding connecting strip 221 of the lower housing 2, is exposed. The fan mounting frame 3 can then be removed from the inward-folding connecting strip 221, and the connecting piece 331 will detach from the positioning groove 220a. Apart from its support plate 31, positioning baffle 32, and connecting vertical plate 33, the fan mounting frame 3 has no other structure that obstructs the cooling fan 4. Users can directly use the other empty spaces on the fan mounting frame 3 to clean the cooling fan 4 without having to release the lock between the cooling fan 4 and the fan mounting hole 310a of the support plate 31. After cleaning, the connecting piece 331 of the fan mounting frame 3 is repositioned into the positioning groove 220a. The shape of the positioning groove 220a restricts the connecting piece 331, allowing for quick alignment of the frame connecting hole 330 with the lower shell connecting hole 220b. Then, the upper shell 1 is replaced on top of the lower shell 2. The upper shell cover 11 abuts against the inward-folding connecting strip 221, causing the two upper shell side plates 12 and the two lower shell side plates 22 to form a cubical receiving space, completing the docking and locking of the upper shell 1 and lower shell 2. Simultaneously, the fan mounting frame 3 is locked onto the inward-folding connecting strip 221. Based on the above computer power supply housing, disassembly and assembly can be completed by tightening only a few fasteners, allowing for quick separation of the upper shell 1, lower shell 2, and fan mounting frame 3, facilitating cleaning of the cooling fan 4 and saving time and effort.

[0035] Specifically, the top of the upper shell cover plate 11 is provided with a fan inlet 110b, and the support plate 31 is provided with an airflow channel 310b corresponding to the fan inlet 110b. The upper shell cover plate 11 has four upper shell connecting holes 110a, which are arranged around the fan inlet 110b. The corresponding inward connecting strip 221 is provided with four positioning grooves 220a. Each connecting vertical plate 33 has two connecting pieces 331, which are located at the front and rear ends of the connecting vertical plate 33 respectively. That is, the frame connecting holes 330, which serve as the connection points of the fan mounting frame 3, are provided with four holes located at the four corners of the fan mounting frame 3. This helps to maintain the force balance when the fan mounting frame 3 is placed on the lower shell 2, ensuring the stable connection of the fan mounting frame 3.

[0036] Furthermore, in addition to fixing the cooling fan 4 through the fan mounting hole 310a, as one embodiment of the fan mounting frame 3, a fan frame fixing strip 332 is connected to the opposing surfaces of the two connecting vertical plates 33. The fan frame fixing strip 332 extends toward the positioning baffle 32. When the cooling fan 4 is placed on the support plate 31, the cooling fan 4 includes a fan frame and a fan body installed in the fan frame. A gap is opened on the side of the fan frame. Figure 4 and Figure 5 As shown, when the cooling fan 4 is installed in the fan mounting frame 3, the fan frame fixing strip 332 can be inserted into the slots on both sides of the cooling fan 4. The two fan frame fixing strips 332 clamp and fix the two sides of the cooling fan 4. The left and right sides of the cooling fan 4 are pressed and positioned by the fan frame fixing strips 332, while the rear side of the cooling fan 4 is pressed and positioned by the positioning baffle 32. This can reduce the number of fan mounting holes 310a and further simplify disassembly and assembly.

[0037] To ensure that the fan frame fixing strip 332 clamps the cooling fan 4 while facilitating its removal from the fan frame fixing strip 332, in this embodiment, the fan frame fixing strip 332 is made of an elastic material strip. The fan frame fixing strip 332 is suspended above the support plate 31, forming a gap between it and the support plate 31. When the fan frame fixing strip 332 is inserted into the openings on both sides of the cooling fan 4, it can press the structure below the opening of the cooling fan 4 onto the support plate 31, eliminating the need to fix the cooling fan 4 through the fan mounting hole 310a.

[0038] To facilitate the alignment of the cooling fan 4 with the insertion position of the fan frame fixing strip 332, the thickness of the front end of the fan frame fixing strip 332 gradually decreases away from the positioning baffle 32, forming an inclined surface that guides the two sides of the cooling fan 4 to connect, making it easier for the cooling fan 4 to be inserted into the fan frame fixing strip 332 from the front end relative to the positioning baffle 32.

[0039] Specifically, bottom edge seals 211 extend upward from the front and rear sides of the lower shell bottom plate 21, and side edge seals 222 extend upward from the front and rear sides of the lower shell side plate 22. The upper shell side plate 12 overlaps the side edge seals 222 and is sandwiched between the side edge seals 222 and the bottom edge seals 211. The side edge seals 222 and the bottom edge seals 211 define the mating position of the upper shell side plate 12, which facilitates the alignment of the upper shell 1 with the lower shell 2. Furthermore, the overlap of the bottom edge seals 211, the side edge seals 222, and the inward connecting strips 221 with the upper shell 1 ensures the sealing of the connection between the upper shell 1 and the lower shell 2, preventing gaps.

[0040] like Figure 3 and Figure 5As shown, the positioning groove 220a is formed by the recess of the top surface of the inward-turning connecting strip 221. The thickness of the connecting piece 331 is the same as the depth of the positioning groove 220a. When the connecting piece 331 is placed in the positioning groove 220a, the top surface of the connecting piece 331 above the positioning groove 220a is at the same height as the top surface of the inward-turning connecting strip 221. The upper shell cover plate 11 is attached to the connecting piece 331, pressing the connecting piece 331 against the positioning groove 220a.

[0042] The above description is only a specific embodiment of this application.
