[0002] A shielding case is a tool used to shield electronic signals. Its function is to shield the influence of external electromagnetic waves on the internal circuit and the external radiation of electromagnetic waves generated inside. Shielding is a device method in electrical engineering. In order to prevent the external electric field, magnetic field or electromagnetic field from interfering with the internal equipment or to avoid the influence of the electromagnetic field of the equipment on the outside world, the equipment is placed in a closed or nearly closed metal shell or metal mesh cover. This metal shell or mesh cover is called a shielding case.

[0003] The existing auxiliary source input filter shielding cover usually has a fixed structure, which makes it difficult to maintain and inspect the internal equipment. In order to maintain or inspect the internal equipment of the shielding cover, the shielding cover needs to be completely removed, which not only increases the labor intensity and time cost of the maintenance process, but also may cause equipment damage or performance degradation during disassembly and reinstallation. For this reason, an auxiliary source input filter shielding cover is proposed. Utility Model Content

[0028] See also Figure 1-5The utility model provides a technical solution: an auxiliary source input filter shielding cover, comprising a shielding cover body 1 that can be installed on one side of the auxiliary source input filter, a shielding cover 4 is arranged on one side of the shielding cover body 1, the shielding cover body 1 and the cover plate 21 are made of tinplate, a side plate 3 is integrally formed on one side of the shielding cover 4, and three teeth 7 are integrally formed on one side of the side plate 3, the three teeth 7 are inserted into the inner side of the installation groove of the filter, the wire passes through the notch 5 and passes through the inside of the shielding cover body 1, one side of the side plate 3 abuts against one side of the filter, and the installation of the shielding cover body 1 is completed at this time, a notch 5 is arranged on one side of the shielding cover 4, and a maintenance component 2 is arranged on one side of the shielding cover 4;

[0029] In order to facilitate the inspection or maintenance of the inside of the shielding cover body 1, a maintenance component 2 is provided. The maintenance component 2 includes two first limit blocks 22 and a fixing frame 23. A slide groove 25 is provided on one side of the fixing frame 23. A rotating shaft is rotatably connected between the two first limit blocks 22. The pull plate 24 is pulled to one side, and the pull plate 24 drives the slide plate 28 to slide on the inner side of the slide groove 25. At the same time, the slide plate 28 compresses the spring sheet 26, so that the slide plate 28 drives the baffle 27 to move to one side. A through groove 6 is provided on one side of the shielding cover 4. A cover plate 21 located on one side of the through groove 6 is fixed on the outer side of the rotating shaft. A slide plate 28 is slidably connected to the inner side of the slide groove 25. A pull plate 24 is fixed on one side of the slide plate 28. The cover plate 21 rotates around the rotating shaft on one side of the first limit block 22, and the through groove 6 on one side of the shielding cover 4 is exposed at this time. The equipment inside the shielding cover body 1 can be inspected or repaired through the through groove 6, and there is no need to completely remove the entire shielding cover body 1, which simplifies the maintenance and inspection process.

[0030] In order to facilitate closing the cover 21, two second limit blocks 29 are provided on the inner wall of the slide groove 25, and the second limit block 29 is located on one side of the slide plate 28. A baffle 27 that is movable and runs through one side of the fixing frame 23 is fixed on one side of the slide plate 28. After inspection or maintenance, it is only necessary to pull the pull plate 24 to one side again to make the baffle 27 move to the side of the spring sheet 26, and then close the cover 21. One side of the baffle 27 is located on one side of the cover 21, and a spring sheet 26 is fixedly inserted into the inner wall of the slide groove 25. One end of the spring sheet 26 is attached to one side of the slide plate 28, and the cover 21 is located on the top side of the through groove 6. The pulling force of pulling the pull plate 24 is released. Under the elastic force of the spring sheet 26, the baffle 27 is located on the top side of the cover 21. At this time, the cover 21 is attached to one side of the shielding cover 4, and one side of the fixing frame 23 and the first limit block 22 are both fixed to one side of the shielding cover 4.

[0031] Working principle: When the shielding cover body 1 needs to be installed on one side of the auxiliary source input filter of the new energy vehicle, it is only necessary to insert the three teeth 7 into the inner side of the filter installation slot, and the wire passes through the notch 5 to pass through the inside of the shielding cover body 1. One side of the side plate 3 contacts one side of the filter, and the installation of the shielding cover body 1 is completed at this time;

[0032] When it is necessary to regularly inspect or repair the filter inside the auxiliary source input filter shielding cover body 1, it is only necessary to pull the pull plate 24 to one side. The pull plate 24 drives the slide plate 28 to slide on the inside of the slide groove 25. At the same time, the slide plate 28 compresses the spring piece 26, so that the slide plate 28 drives the baffle 27 to move to one side, so that the baffle 27 leaves the top side of the cover plate 21. At this time, the staff opens the cover plate 21, so that the cover plate 21 rotates around the rotating shaft on the side of the first limit block 22. At this time, the through groove 6 on one side of the shielding cover 4 is exposed. The equipment inside the shielding cover body 1 can be inspected or repaired through the through groove 6. There is no need to completely remove the entire shielding cover body 1, which simplifies the maintenance and inspection process, reduces the labor intensity and time cost during the maintenance process, and improves the convenience of the shielding cover body 1 when in use.

[0033] After inspection or maintenance, it is only necessary to pull the pull plate 24 to one side again so that the baffle 27 moves toward the side of the spring sheet 26, and then close the cover 21 so that the cover 21 is located on the top side of the through slot 6, and release the pulling force of the pull plate 24. Under the elastic force of the spring sheet 26, the baffle 27 is located on the top side of the cover 21. At this time, the cover 21 is attached to one side of the shielding cover 4.
