Description

Technical Field

[0001] This utility model belongs to the field of switching power supply technology, and specifically relates to a housing structure for a switching power supply. Background Technology

[0002] The housing structure of a switching power supply is the physical framework that protects internal circuit components and enables functional integration. Its design incorporates principles of mechanical support, electromagnetic shielding, and heat dissipation management. The housing is typically made of high-strength insulating materials and constructed as a closed space through integrated molding or modular assembly. Internally, structures such as fixing brackets, limiting cylinders, and rollers ensure the orderly arrangement and mechanical fixation of wires, preventing component loosening caused by vibration. The housing structure of the switching power supply provides a dustproof, moisture-proof, and shock-resistant environment for precision components such as EMC filter circuits, rectifier modules, and high-frequency transformers. Simultaneously, a metal shielding layer or conductive coating blocks electromagnetic interference leakage, ensuring the power supply complies with electromagnetic compatibility standards.

[0003] Chinese Patent Publication No. CN222424224U relates to the field of switching power supply technology and discloses a housing structure for a switching power supply. The housing includes a cover plate on the outside and two symmetrically arranged snap-fit ​​components inside the cover plate. This housing structure, through the snap-fit ​​components, allows for easy disassembly of the power supply housing when internal components need to be replaced or repaired. Pressing the two left and right pressing plates, in conjunction with compression springs, causes the two snap-fit ​​shafts to move relative to each other until they disengage from snap-fit ​​grooves on the left and right sides of the inner wall of the housing. Then, the cover plate is pulled forward through the grooves to remove it from the housing. This facilitates the replacement and repair of internal components, eliminating the need for time-consuming screw removal, improving the device's practicality and ease of use.

[0004] In practical use, the heat dissipation holes of this utility model are usually cleaned. However, the cleaning structure of the existing switching power supply housing is usually relatively simple, generally relying on a single cleaning brush. This not only makes it difficult to completely remove stubborn dirt attached to the heat dissipation holes, but also, due to the lack of an effective dustproof isolation mechanism, the particles that fall off during the cleaning process can easily enter the switching power supply through the heat dissipation channel. Dust accumulation may cause local overheating or a decrease in insulation performance, and secondary pollution during the cleaning process can shorten the service life of components. Thus, the practicality of the switching power supply housing structure is somewhat lacking. Utility Model Content

[0005] This utility model proposes a housing structure for a switching power supply to solve the problem of the difficulty in effectively cleaning dust and impurities on switching power supplies in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a housing structure for a switching power supply, comprising:

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Example 1:

[0028] Please see Figure 1-4 This utility model provides a housing structure for a switching power supply, comprising:

[0029] The main body 1 and the outer casing 2 of the switching power supply;

[0030] A heat dissipation mesh 3 is provided on one side of the outer shell 2. A mounting frame 4 is provided on one side of the outer shell 2. A rectangular groove is provided in the mounting frame 4. A threaded rod 5 is rotatably connected in the rectangular groove.

[0031] Positioning plate 6 is set on one side of the inner wall of mounting frame 4. Positioning groove is opened in positioning plate 6. Positioning shaft 7 is rotatably connected in positioning groove. Multiple mounting shafts 8 are provided through one side of positioning groove.

[0032] Multiple cleaning brushes 9 are respectively set at one end of multiple mounting shafts 8. The multiple cleaning brushes 9 are all against one side of the heat dissipation mesh 3. The positioning plates 6 located on both sides of the positioning groove are provided with dust suction grooves. Multiple dust suction holes 10 are provided through one side of each of the two dust suction grooves.

[0033] Specifically, such as Figure 2 As shown, a mounting plate 11 is provided on one side of the positioning plate 6. One end of the mounting plate 11 extends into the rectangular groove and is provided with a threaded hole that is compatible with the threaded rod 5. The threaded rod 5 passes through the threaded hole and is threadedly connected to the side wall of the threaded hole. When the threaded rod 5 rotates, it can drive the mounting plate 11 and the positioning plate 6 to move in the horizontal direction, thereby driving multiple cleaning brushes 9 to move and clean dust and impurities on the surface of the heat dissipation mesh 3.

[0034] Specifically, such as Figure 2 As shown, a servo motor 12 is provided at one end of the mounting frame 4. The servo motor 12 is existing technology and will not be described in detail here. One end of the threaded rod 5 extends to the outside and is set on the output end of the servo motor 12.

[0035] Specifically, such as Figure 3 As shown, a plurality of first bevel gears 13 are provided on the outer side of the positioning shaft 7, and a plurality of mounting shafts 8 are provided at one end with a second bevel gear 14 that is adapted to the first bevel gear 13. The plurality of first bevel gears 13 are respectively meshed with the plurality of second bevel gears 14.

[0036] With its design, when the positioning shaft 7 rotates, it will drive multiple second bevel gears 14 and multiple mounting shafts 8 to rotate through multiple first bevel gears 13 respectively. The multiple mounting shafts 8 will drive multiple cleaning brushes 9 to rotate, which can improve the cleaning effect of stubborn dust and impurities on the surface of the heat dissipation mesh 3.

[0037] Specifically, such as Figure 3 and Figure 4As shown, a rack plate 15 is provided on one side of the upper end of the outer shell 2. One end of the positioning shaft 7 extends to the outside through one side of the positioning groove and is provided with a positioning wheel 16 that is adapted to the rack plate 15. The positioning wheel 16 is meshed with the rack plate 15. The positioning plate 6 drives the positioning shaft 7 to move. With the rack plate 15 and the positioning wheel 16, the positioning shaft 7 can rotate, thereby driving multiple cleaning brushes 9 to rotate.

[0038] Specifically, such as Figure 3 and Figure 4 As shown, a filter box 17 is provided on one side of the positioning plate 6, and transmission pipes 18 are provided on both sides of the filter box 17. The two transmission pipes 18 are respectively connected to two dust collection slots. The filter box 17 can draw air from the two dust collection slots through the two transmission pipes 18 to create a negative pressure state. Thus, multiple dust collection holes 10 on one side of the two dust collection slots can be used to absorb dust and impurities on the surface of the heat dissipation mesh 3. This not only improves the cleaning effect of the heat dissipation mesh 3, but also avoids secondary pollution of the casing structure of the switching power supply caused by the cleaned dust and impurities.

[0039] Specifically, such as Figure 3 and Figure 4 As shown, a pump body 19 is provided on one side of the filter box 17. The pump body 19 is existing technology and will not be described in detail here. The air extraction end of the pump body 19 is connected to the filter box 17. The pump body 19 can extract the air in the filter box 17 to make it into a negative pressure state, so that the air in the two dust collection slots can be extracted through the two transmission pipes 18 respectively.

[0040] Example 2:

[0041] Please see Figure 1-4 This utility model provides a housing structure for a switching power supply, comprising:

[0042] The main body 1 and the outer casing 2 of the switching power supply;

[0043] A heat dissipation mesh 3 is provided on one side of the outer shell 2. A mounting frame 4 is provided on one side of the outer shell 2. A rectangular groove is provided in the mounting frame 4. A threaded rod 5 is rotatably connected in the rectangular groove.

[0044] Positioning plate 6 is set on one side of the inner wall of mounting frame 4. Positioning groove is opened in positioning plate 6. Positioning shaft 7 is rotatably connected in positioning groove. Multiple mounting shafts 8 are provided through one side of positioning groove.

[0045] Multiple cleaning brushes 9 are respectively set at one end of multiple mounting shafts 8. The multiple cleaning brushes 9 are all against one side of the heat dissipation mesh 3. The positioning plates 6 located on both sides of the positioning groove are provided with dust suction grooves. Multiple dust suction holes 10 are provided through one side of each of the two dust suction grooves.

[0046] Specifically, such as Figure 3As shown, each of the multiple cleaning brushes 9 has a scraper 20 on one side, and the multiple scrapers 20 abut against one side of the positioning plate 6.

[0047] Through its design, multiple cleaning brushes 9 can drive multiple scraper plates 20 to rotate when they rotate. The multiple scraper plates 20 will clean the multiple suction holes 10 on one side of the multiple positioning plates 6 respectively, and the surface dust and impurities will block them, thereby ensuring the cleaning effect of the housing structure of the switching power supply.

[0048] See Figure 1-4 After prolonged use of the switching power supply's housing structure, the heat dissipation mesh 3 on its surface needs to be cleaned. During cleaning, the servo motor 12 is first started. The output of the servo motor 12 drives the threaded rod 5 to rotate, which in turn moves the mounting plate 11 and positioning plate 6 horizontally. The positioning plate 6 then moves multiple cleaning brushes 9 to clean dust and impurities from the surface of the heat dissipation mesh 3. During this movement, the positioning plate 6 drives the positioning shaft 7 to move. This, in conjunction with the rack plate 15 on one side of the housing 2 and the positioning wheel 16 at one end of the positioning shaft 7, allows the positioning shaft 7 to rotate during movement. When the positioning shaft 7 rotates, it drives multiple first bevel gears 13 to rotate, which in turn drive multiple second bevel gears 13 to rotate. The bevel gear 14 and multiple mounting shafts 8 rotate, which in turn drive multiple cleaning brushes 9 to rotate, improving the cleaning effect on the heat dissipation mesh 3. While the multiple cleaning brushes 9 are cleaning dust and impurities on the surface of the heat dissipation mesh 3, the pump body 19 is activated. The air extraction end of the pump body 19 draws air from the filter box 17. In conjunction with the two transmission pipes 18, air can be drawn from the two dust collection slots. Thus, the surface of the heat dissipation mesh 3 and the dust and impurities that have been cleaned can be absorbed and cleaned through multiple dust collection holes 10. When the multiple cleaning brushes 9 rotate, they will drive multiple scraper plates 20 to rotate, which can clean the multiple dust collection holes 10 on one side of the positioning plate 6, preventing them from becoming blocked, thereby ensuring the cleaning effect on the housing structure of the switching power supply.
