[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-3 It is understood that this utility model provides a technical solution: an embedded hardware structure for a new energy vehicle battery, including a battery box 1, a battery management module 2, a battery pack 3, and a wiring hole 4. The battery box 1 houses the battery management module 2 for managing and monitoring the battery pack 3. The battery pack 3 is installed inside the battery box 1, and the battery pack 3 is electrically connected to the battery management module 2. A wiring hole 4 for wiring the battery management module 2 is provided on the side of the battery box 1 closest to the wiring hole 4. An air inlet 5 for air intake is provided on the same side of the battery box 1 closest to the wiring hole 4. An exhaust vent 6 for exhaust is provided on the side of the battery box 1 closest to the air inlet 5. A support plate 7 and a fixing block 8 are welded to the outside of the exhaust vent 6. A positioning block 9 is slidably connected inside the fixing block 8. A first spring 10 for resetting the positioning block 9 is connected between the outside of the positioning block 9 and the inside of the fixing block 8. A connecting plate 11 is connected to the top of the positioning block 9. A semi-circular groove is opened on the surface of the connecting plate 11. A cooling fan body 12 for exhausting hot air around the battery management module 2 from inside the battery box 1 is provided between the support plate 7 and the fixing block 8. The model of the cooling fan body 12 is FW8025HBL2. The cooling fan body 12 is electrically connected to the battery management module 2. A connecting block 13 for the bottom of the positioning block 9 is connected to the top of the cooling fan body 12.

[0021] exist Figure 2 In the middle: a connecting post 14 is connected to the outside of the fixing block 8, and a horizontal plate 15 is rotatably connected to the outside of the connecting post 14.

[0022] exist Figure 2In the middle: The bottom of the horizontal plate 15 is connected to a rubber block 16 for limiting the connection plate 11. The rubber block 16 matches the size of the semi-circular groove on the surface of the connection plate 11.

[0023] In practice, since the battery management module 2 is installed inside the battery box 1, its heat dissipation effect is insufficient, which will affect its normal use over time. To address this, the connecting plate 11 can be pulled away from the fixing block 8. As the connecting plate 11 moves, it compresses the first spring 10 by driving the positioning block 9. Once the bottom of the positioning block 9 is inside the fixing block 8, the cooling fan body 12 can be placed on the support plate 7, positioning it in front of the exhaust vent 6. Simultaneously, the connecting block 13 at the top of the cooling fan body 12 can move directly below the positioning block 9. At this point, the connecting plate 11 is released, allowing the first spring 10 to reset. When the first spring 10 resets, it drives the positioning block 9 to reset as well. When the positioning block 9 resets, its bottom can... The horizontal plate 15 is inserted into the connecting block 13 to limit the connection block 13 and the cooling fan body 12. Then, the horizontal plate 15 is pulled towards the top of the connecting plate 11. When the horizontal plate 15 moves, it can rotate through the connecting post 14. When the horizontal plate 15 moves the rubber clip 16 to the side of the connecting plate 11, the rubber clip 16 will squeeze the side of the connecting plate 11, causing the rubber clip 16 to undergo elastic deformation. When the rubber clip 16 moves to the top of the semi-circular groove, the rubber clip 16 can be reset, so that the rubber clip 16 can be engaged in the semi-circular groove at the top of the connecting plate 11. At this time, the horizontal plate 15 can limit the connection plate 11 and the positioning block 9, so that the first spring 10 cannot undergo elastic deformation, and the positioning block 9 is not easy to slide out from the inside of the connecting block 13.

[0024] See Figures 1-3 It can be seen that the heat dissipation fan body 12 can dissipate the heat around the battery management module 2, thereby playing a role in heat dissipation and improving the heat dissipation effect of the battery management module 2, so that the battery management module 2 is less likely to be affected by high temperature during long-term use.

[0025] exist Figure 1 and Figure 4 In the middle: A connecting seat 17 is connected to the outside of the battery management module 2. A second spring 18 for the telescopic reset of the limiting block 19 is connected inside the connecting seat 17. The limiting block 19 is connected to one end of the second spring 18, and the end of the limiting block 19 is an arc-shaped surface.

[0026] exist Figure 1 and Figure 4In the middle: The top of the battery management module 2 is provided with an insulating plate 20 for insulation. The bottom of the insulating plate 20 near the connector 17 is connected to a plug block 21. Both sides of the plug block 21 are provided with arc-shaped grooves that match the end size of the limit block 19. The plug block 21 and the connector 17 form a plug-in structure. The top of the insulating plate 20 is connected to a vertical plate 22. The vertical plate 22 and the insulating plate 20 are an integral structure.

[0027] In practice, after the battery management module 2 and battery pack 3 are installed, a corresponding power test needs to be performed. Since the battery management module 2 is energized, workers may accidentally touch its top during testing, posing a risk of electric shock. Before powering on the battery management module 2, the vertical plate 22 can be pulled to move the insulating plate 20 directly above the battery management module 2, aligning the insertion block 21 at the bottom of the insulating plate 20 with the connecting seat 17 below. Then, the insulating plate 20 can be slowly lowered, allowing the insertion block 21 to be inserted into the connecting seat 17. When the plug-in block 21 is inside the connector 17, the bottom of the plug-in block 21 can press the arc-shaped surfaces of the two sets of limiting blocks 19, so that the limiting blocks 19 compress the second spring 18. At this time, the limiting blocks 19 contract. When the bottom of the plug-in block 21 is inserted into the connector 17 at the maximum distance, the plug-in block 21 can drive the arc-shaped groove to move to the outside of the end of the limiting block 19, so that the second spring 18 can be reset. When the second spring 18 is reset, it can drive the limiting block 19 to be reset. When the limiting block 19 is reset, its end can be engaged in the arc-shaped groove on the plug-in block 21, thereby fixing the plug-in block 21. At this time, the insulating plate 20 can be installed on the top of the battery management module 2.

[0028] See Figure 1 and Figure 4 It can be seen that the top of the battery management module 2 can be protected by the insulating plate 20, thereby preventing people from accidentally touching the top of the battery management module 2 during the test and causing electric shock, thus improving the safety of the battery management module 2 during the test.
