[0024] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Reference Figure 1 , Figure 2 and Figure 3 An embodiment of this utility model provides an integrated thermal management device for new energy vehicles, comprising a device box 1, a protective cover 2 on the upper surface of the device box 1, a dustproof plate 3 inside the protective cover 2, a sliding column 4 slidably connected inside the dustproof plate 3, a sliding piece 5 fixedly connected to the outer wall of the sliding column 4, the outer wall of the sliding piece 5 slidably connected to the inside of the dustproof plate 3, a retaining bead 6 fixedly connected to the outer wall of the sliding piece 5, the outer wall of the retaining bead 6 slidably connected to the inside of the protective cover 2, a first spring 7 on the outer wall of the sliding column 4, one end of the first spring 7 fixedly connected to the inside of the dustproof plate 3, the other end of the first spring 7 fixedly connected to the outer wall of the sliding piece 5, an exhaust fan 8 inside the protective cover 2, and a circulation component inside the protective cover 2.

[0026] Specifically, the upper surface of the device box 1 is provided with a protective cover 2, which can protect the internal components. Inside the protective cover 2, there is a dustproof plate 3, which can prevent dust. By moving the dustproof plate 3 inside the protective cover 2, the locking ball 6 can be moved inside the protective cover 2. The protective cover 2 can squeeze the locking ball 6, which can drive the sliding plate 5 to slide. The sliding plate 5 can drive the sliding column 4 to slide. The sliding plate 5 can drive the first spring 7 to compress. The first spring 7 can rebound and squeeze the locking ball 6 inside the protective cover 2, thereby achieving the effect of quick disassembly of the dustproof plate 3.

[0027] Reference Figure 4 The circulation component includes a circulating water tank 9, the lower surface of which is fixedly connected to the inside of the device box 1. A water pump 10 is provided on the outer wall of the circulating water tank 9. One end of a water pipe 11 is fixedly connected to the output end of the water pump 10. The other end of the water pipe 11 is fixedly connected to a battery box 12. The lower surface of the battery box 12 is fixedly connected to the inside of the device box 1.

[0028] Specifically, the device box 1 serves to fix the circulating water tank 9, which in turn circulates water. A water pump 10 is installed on the outer wall of the circulating water tank 9. By starting the water pump 10, the heated water inside the circulating water tank 9 can be driven into the water pipe 11. An electric heating wire is installed inside the circulating water tank 9 to heat the water. The heated water enters the battery box 12 through the water pipe 11. A sealed space is provided at the inner edge of the battery box 12, allowing hot water to flow in to preheat the battery box 12 and prevent uneven heating of the battery box 12, which could lead to a short service life of the battery box 12.

[0029] Reference Figure 5 The protective cover 2 has a sliding connection to a connecting frame 13, a handle 14 is fixedly connected to the upper surface of the connecting frame 13, and a fan 15 is provided on the lower surface of the connecting frame 13.

[0030] Specifically, the protective cover 2 has a connecting frame 13 inside, which provides fixed support for the fan 15. The upper surface of the connecting frame 13 has a handle 14, which facilitates the disassembly of the fan 15.

[0031] Reference Figure 5 and Figure 6The connecting frame 13 is internally fixedly connected to a mounting block 16, and internally slidably connected to a slide rod 17. A slide block 18 is fixedly connected to the outer wall of the slide rod 17, and internally fixedly connected to a rotating shaft 19. A rotating plate 20 is rotatably connected to the outer wall of the rotating shaft 19, and internally rotatably connected to a rotating shaft 21. A sliding plate 22 is fixedly connected to the outer wall of the rotating shaft 21, and its outer wall is slidably connected to the interior of the mounting block 16. A second spring 23 is provided on the outer wall of the sliding plate 22, and its outer wall is fixedly connected to the interior of the mounting block 16. A locking block 24 is fixedly connected to the outer wall of the sliding plate 22, and its outer wall is slidably connected to the interior of the protective cover 2.

[0032] Specifically, the connecting bracket 13 fixes the mounting block 16, which in turn mounts the fan 15. Pressing the slide bar 17 causes the sliding block 18 to slide inside the mounting block 16. The sliding block 18 moves the rotating shaft 19, which in turn rotates the rotating plate 20. The rotating plate 20 rotates on the outer wall of the rotating shaft 21, causing the sliding plate 22 to slide inside the mounting block 16. The sliding plate 22 compresses the second spring 23, which then rebounds, causing the locking block 24 to slide inside the protective cover 2. The locking block 24 engages with the protective cover 2, enabling the fan 15 to be installed quickly and effectively dissipating heat from the device.

[0033] Working principle: When the device is needed, the thermal management device is first installed in the body of the new energy vehicle, and the dustproof plate 3 is installed on the protective cover 2. By directly pressing the dustproof plate 3, the locking ball 6 can slide on the outer wall of the protective cover 2, and at the same time, the sliding piece 5 can be moved inside the dustproof plate 3, thereby driving the first spring 7 to compress, and at the same time driving the sliding column 4 to slide inside the dustproof plate 3, so that the locking ball 6 squeezes the protective cover 2, thereby achieving the effect of installing the dustproof plate 3 on the protective cover 2. The dustproof plate 3 plays a dustproof role. By quickly removing the dustproof plate 3, the dustproof plate 3 can be thoroughly cleaned to avoid clogging and affecting the dustproof effect.

[0034] A circulation component is installed inside the device box 1 to preheat the battery box 12, avoiding uneven heating that could shorten the service life of the battery box 12. By starting the water pump 10, the heated water inside the circulating water tank 9 can be driven into the water pipe 11, and then into the space reserved at the inner edge of the battery box 12 through the water pipe 11 to preheat the battery pack inside the battery box 12. After the heated water flows through the battery box 12, it returns to the circulating water tank 9 through the pipe to complete the circulating heating.

[0035] When the fan 15 needs to be installed, pressing the slide bar 17 can cause the sliding block 18 to slide inside the mounting block 16, thereby causing the rotating plate 20 to rotate on the outer wall of the rotating shaft 19 and the rotating shaft 21. At the same time, it can also cause the sliding plate 22 to slide inside the mounting block 16, thereby causing the locking block 24 to slide into the mounting block 16. Simultaneously, it causes the second spring 23 to be compressed. At this time, by holding the handle 14, the connecting bracket 13 can be slid into the protective cover 2. Through the rebound of the second spring 23, the locking block 24 can be slid into the protective cover 2, thereby achieving the effect of quick installation of the fan 15 and effective heat dissipation of the internal components. This device can not only achieve the effect of quick disassembly of the dustproof plate 3 and achieve effective dust prevention, but also achieve the effect of quick disassembly of the fan 15 and achieve effective heat dissipation.

[0036] 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.
