[0002] The charger casing is a protective shell that encloses the charger's internal circuit components, transformers, capacitors, and other core components. Its main function is to isolate external dust, moisture, and physical impacts, while providing stable mounting support for internal components to ensure the safety and structural integrity of the charger during use. The heat dissipation and dustproof structure is a functional component integrated into the charger casing. This structure has heat dissipation holes in the casing corresponding to the internal heat-generating components to allow air circulation, dissipate internal heat, and prevent dust accumulation from reducing the heat dissipation efficiency of the components or causing short circuits.

The charger input terminal 2 is used to introduce external electrical energy into the charger, providing initial electrical energy input for the charger's energy conversion. The charger output terminal 3 is used to output the stable electrical energy converted internally to the device to be charged, realizing the transfer of electrical energy. The first baffle 5 and the second baffle 6 are used to quickly repair damaged components when they are damaged. The charger heat dissipation hole 7 is used to dissipate the heat generated by the internal components to the outside of the housing when the charger is working, preventing the internal temperature from being too high, which could lead to a decrease in component performance, a shortened lifespan, or even burnout, and ensuring stable operation of the charger.

[0020] Reference Figure 3 and Figure 4 The moving component includes a bidirectional threaded rod 9, the outer wall of which is rotatably connected to the inside of the charger housing 1, the outer wall of which is threadedly connected to the inside of the first baffle 5, the outer wall of which is threadedly connected to the inside of the second baffle 6, and the outer wall of which is fixedly connected to the first handle 10. Specifically, the first handle 10 is convenient for maintenance personnel to hold and open the first baffle 5 and the second baffle 6, and the bidirectional threaded rod 9 is used to convert the rotational movement of the first handle 10 into the vertical movement of the first baffle 5 and the second baffle 6. Example 2

[0021] Reference Figure 5 , Figure 6 and Figure 7A dust cover 11 is slidably connected to the outer wall of the first fixing block 8. The outer wall of the dust cover 11 is slidably connected to the outer wall of the second fixing block 17. The outer wall of the dust cover 11 is slidably connected to the inner wall of the charger housing 1. A limit box 12 is fixedly connected to the outer wall of the second fixing block 17. A second handle 14 is slidably connected to the inner wall of the limit box 12. A slide plate 13 is fixedly connected to the lower surface of the second handle 14. The outer wall of the slide plate 13 is slidably connected to the inner wall of the limit box 12. A short column 16 is fixedly connected to the outer wall of the slide plate 13. The outer wall of the short column 16 is slidably connected to the inner wall of the first fixing block 8. The outer wall of the short column 16 is slidably connected to the inner wall of the dust cover 11. The outer wall of the short column 16 is slidably connected to the inner wall of the second fixing block 17. The outer wall of the short column 16 is slidably connected to the inner wall of the limit box 12. One end of a spring 15 is fixedly connected to the outer wall of the slide plate 13. The other end of the spring 15 is fixedly connected to the inner wall of the limit box 12. Specifically, the dust cover 11 is used to cover the heat dissipation holes 7 of the charger to prevent finer dust particles from entering the shell. It can also be used by maintenance personnel to remove the dust cover 11 for cleaning periodically, so as to avoid the dust accumulation on the dust cover 11 affecting the ventilation efficiency of the heat dissipation holes and ensure the stability of the dust prevention and heat dissipation functions. One end of the spring 15 is fixedly connected to the outer wall of the slide plate 13, and the other end of the spring 15 is fixedly connected to the inner wall of the limiting box 12 to limit the elastic range of the spring 15. When the dust cover 11 needs to be fixed after cleaning, the first fixing block 8, the second fixing block 17 and the dust cover 11 can be quickly fixed by the reset of the spring 15. Example 3

[0022] Reference Figure 8 The second fixing block 17 has an internal threaded connection to a bolt 18, the outer wall of the bolt 18 is threaded to the inner wall of the dust cover 11, and the outer wall of the bolt 18 is connected to the inner wall of the first fixing block 8. Specifically, the first fixing block 8, the second fixing block 17 and the dust cover 11 can be fixed by rotating the bolt 18. When the dust cover 11 needs to be cleaned, rotating the bolt 18 can quickly disassemble and clean the dust cover 11.

[0023] Working principle: When the charger needs internal maintenance, rotating the first handle 10 causes the bidirectional threaded rod 9 to rotate, which in turn rotates the bidirectional threaded rod 9 inside the charger housing 1. This rotation causes the first baffle 5 to move, sliding against the inner wall of the charger housing 1 and the outer wall of the light bar 4. Simultaneously, the rotation of the bidirectional threaded rod 9 moves the second baffle 6, causing it to slide against both the inner and outer walls of the charger housing 1 and the light bar 4. This process allows for internal maintenance of the charger, facilitating repairs and preventing damage to internal components due to unstable movement. It also enables more accurate troubleshooting and maintenance.

[0024] When the dust cover 11 needs to be disassembled, pull the second handle 14, causing it to slide against the inner wall of the limit box 12 during movement. This causes the slide plate 13 to move, sliding against the inner wall of the limit box 12. During this process, the slide plate 13 moves, causing the spring 15 to move, which in turn moves the short column 16. The short column 16 slides against the inner walls of the first fixing block 8 and the second fixing block 17, and simultaneously slides against the inner wall of the dust cover 11. When the short column 16 slides out of the dust cover 11, the dust cover 11 can be disassembled. After disassembly, release the second handle 14. The return of the spring 15 will quickly fix the dust cover 11, thus achieving the effect of disassembling and assembling the dust cover 11. This facilitates the quick removal and cleaning of the dust cover 11 when dust accumulates on its surface.

[0025] In actual use, the heat dissipation holes and dustproof structure of the charger shell not only enable the internal components of the charger to be inspected, which is beneficial for maintenance personnel, but also prevents damage to the internal components of the charger caused by unstable movement during maintenance. This allows maintenance personnel to more accurately diagnose and maintain the fault. In addition, it also enables the dust cover 11 to be disassembled and installed, which is beneficial for maintenance personnel to quickly remove and clean the dust cover 11 when dust accumulates on its surface.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
