[0002] Most of the batteries in the power system of new energy vehicles are arranged under the floor of the vehicle body, which has a relatively harsh installation environment. As the carrier of the power battery, the battery box shell plays a key role in ensuring the safe and reliable operation of the power battery. The spontaneous combustion of the battery system of new energy vehicles is mainly caused by the following factors: one is the defect of the single battery cell; the second is the ignition of the poor contact of the connector; the third is the fire caused by the short circuit; the fourth is the fire caused by the impact deformation, etc. Data shows that about 25% of the fires occur in the parking state, about 35% of the fires occur in the charging state, and about 40% of the fires occur in the driving state. And once the battery system catches fire, it will explode quickly, leaving the user with a short time to leave the vehicle, posing a greater threat to life safety.
[0003] Therefore, it is necessary to provide a clean energy vehicle battery to solve the above problems.
[0004] It should be noted that the above information disclosed in this background technology section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute the prior art. Summary of the invention

[0043] Embodiment 1: Figure 1-Figure 12 As shown, the present application provides a clean energy vehicle battery, referring to Figure 1-Figure 2 , Figure 11-Figure 12 , including an outer upper shell 11, an outer lower shell 12, an inner upper shell 21, and an inner lower shell 22; the inner upper shell 21 is suspended on the inner side of the outer upper shell 11 by bolts, the inner lower shell 22 is suspended on the inner side of the outer lower shell 12 by bolts, the inner upper shell 21 and the inner lower shell 22 are arranged oppositely and engaged, and the outer upper shell 11 and the outer lower shell 12 are arranged oppositely and engaged; the inner cavity composed of the inner upper shell 21 and the inner lower shell 22 is installed with a constant temperature module, a battery module, a battery control module, and a smoke module from bottom to top. The inner upper shell 21 and the inner lower shell 22 are installed in a static seal, and the inner cavity formed by the inner upper shell 21 and the inner lower shell 22 is filled with nitrogen; the outer top of the outer upper shell 11 is fixedly installed with a separation assembly 5, and the separation assembly 5 is composed of a mother square column 51 and a sub-square column 52; one end of the mother square column 51 away from the outer upper shell 11 is fixedly connected to the chassis, one end of the sub-square column 52 is fixedly connected to the outer upper shell 11, and the other end of the sub-square column 52 is slidably installed inside the mother square column 51;
[0044] Reference Figure 1 , Figure 3 A plurality of grooves 111 are provided on the outer top of the outer upper shell 11, and a fire-fighting component is installed in the grooves 111. A nitrogen tank 112 is installed on the inner top of the outer upper shell 11. One side of the nitrogen tank 112 is connected to the fire-fighting component through a pipeline, and a pressure relief valve is installed in parallel on the pipeline; a deflation valve is provided at the bottom end of the nitrogen tank 112. The outer upper shell 11 and the outer lower shell 12 are statically sealed, and the inner cavity formed is filled with nitrogen; thus, nitrogen is filled between the inner upper shell 21, the inner lower shell 22 and between the outer upper shell 11 and the outer lower shell 12, which can further reduce the impact of the battery module in high temperature weather. The nitrogen tank 112 is used to constantly fill the space between the outer upper shell 11 and the outer lower shell 12 with nitrogen.

When the nitrogen pressure between the outer upper shell 11 and the outer lower shell 12 is still too high, the pressure relief valve is opened, and the nitrogen in the outer upper shell 11 and the outer lower shell 12 is guided to the outside through the pipeline. Then, a slight positive pressure of the gas between the space between the inner upper shell 21 and the inner lower shell 22 and the space between the outer upper shell 11 and the outer lower shell 12 is achieved, so that the gas inside the battery can be isolated from the external gas, thereby reducing the degree of environmental pollution.

One side of the folding assembly 6 is fixedly installed at the bottom of the groove 111, and the pop-up mechanism 7 is fixed at the side of the folding assembly 6 away from the bottom of the groove 111. A plurality of nozzles are installed on the top of the pop-up mechanism 7, and one end of the nozzle is connected to the nitrogen tank 112 through a pipeline; thus, when the battery spontaneously ignites, the internal nitrogen can slow down the spread of the fire. At the same time, the folding assembly 6 stretches to make the pop-up mechanism 7 placed horizontally in the groove 111 stand upright, and then the pop-up mechanism 7 stretches to push the outer upper shell 11 downward, and the separation assembly 5 is disjointed, so that the battery is separated from the vehicle body as a whole. At the same time, the top of the pop-up mechanism 7 stretches to the surroundings, and a plurality of nozzles are arranged at intervals. Then the nitrogen tank 112 supplies gas to the nozzle, so that the battery shell is filled with nitrogen to isolate the fire source, buying time for the user to leave the vehicle.

While achieving nitrogen isolation and fire extinguishing, the flame is guided downward by the gas rushing downward, further reducing the damage to the car.
