Example

[0030] The new energy battery assembly with safety protection function is provided with a protection structure, which can protect the single battery 4 through the limiting ring 1 5 and the limiting ring 2 6, so that the safety performance of the battery pack is improved, specifically:

[0032] When the new energy battery assembly with safety protection function is used, first, the top cover 2 installed on the upper surface of the shell 1 is opened. Figure 1 As shown, the single cell 4 is vertically inserted and installed between the limiting ring 1 5 and the limiting ring 2 6, so that the lower end of the single cell 4 presses the pressure block 10, and the pressure block 10 slides downward in the partition arranged above the airbag 11, so that the spherical structure at the lower end of the pressure block 10 will press the airbag 11. Since the bag ring 9 inside the limiting ring 1 5 and the limiting ring 2 6 is connected to the airbag 11 through the air pipe 8, the air flow inside the airbag 11 enters the air pipe 8, and then enters the bag ring 9 installed on the inner wall of the limiting ring 1 5 and the limiting ring 2 6 through the air pipe 8 in turn, so that the bag ring 9 expands and tightly wraps the single cell 4 to prevent looseness, and then the insulating ring 7 is installed in a sleeve-type manner on the upper end of the single cell 4 to prevent the single cell 4 from leaking electricity, so that each single cell 4 is protected and safer to use.

[0033] The new energy battery assembly with safety protection function is also provided with a heat dissipation structure, which can ventilate the inside of the battery pack by rotating the rotating plate 13 to prevent the temperature of the single battery 4 from being too high, specifically:

Since the lower end of the shaft 14 is connected to the upper surface of the rotating plate 13, the rotating plate 13 will rotate. At the same time, since the toothed chain 15 is connected to the shafts 14 installed on the upper surfaces of all the rotating plates 13, Figure 3 As shown, all the rotating plates 13 rotate so that the front surface of the housing 1 is opened to allow the battery pack to be ventilated.
