[0018] The present invention will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0019] like Figures 1 to 3 In the embodiment of the new energy battery box of this utility model shown, the new energy battery box includes a box body 1, a sealing connecting ring 2 on the top of the box body 1, a sealing platform 3 fixedly connected to the inner side of the box body 1, a box cover 4 fixed to the sealing platform 3 with screws, a battery compartment 5 under the sealing platform 3, a battery compartment 5 with multiple battery cells 51, hollow partitions 6 around the battery cells 51, a management compartment 7 on one side of the battery compartment 5, a connecting sleeve 8 on the partition 6 between the management compartment 7 and the battery compartment 5, and a functional interface 9 opened at the position of the management compartment 7 on the box cover 4.

[0020] Specifically, the new energy battery is encapsulated in the battery compartment 51 and connected to the management system of the management compartment 7 via the connecting sleeve 8 (existing technology, not within the scope of this application, and will not be described in detail here). The box cover 4 and the sealing platform 3 are fixed with screws. The functional interface 9 on the box cover is used to connect to the electrical equipment. The hollow partition 6 can be used as a refrigerant compartment for cooling the battery. The box body 1 of the new energy battery box is sealed and connected to the electrical equipment via the sealing connecting ring 2.

[0021] In one embodiment of this application, preferably, the height of the partition 6 is the same as the height of the sealing platform 3, and the cover 1 is fixed to the partition 6 with screws at the position of the partition 6, so as to isolate the battery cells 51 from each other and the battery cells 51 from the management compartment 7, and prevent the impact of a single battery cell 51 or management compartment 7 on other equipment.

[0022] In one embodiment of this application, preferably, a sealing gasket 10 adapted to the sealing platform 3 and the battery compartment 51 is provided between the sealing platform 3 and the cover 4 to prevent water leakage in a certain functional area from affecting other equipment.

[0023] In one embodiment of this application, preferably, the bottom of the housing 1 is provided with a finned radiator 11, and the side plate of the housing 1 extends downward to form a surrounding plate (not marked in the figure) to the bottom of the radiator 11 for heat dissipation of the new energy battery box, and the side plate of the housing 1 extends downward to protect the radiator 11 in case of impact.

[0024] In one embodiment of this application, preferably, the radiator 11 includes a base plate 1101 and fins 1102. The fins 1102 are fixedly connected to the base plate 1101. A connecting piece 1103 is fixedly connected to the base plate 1101. A fixing groove 1104 is provided on the surrounding plate for the connecting piece 1103 to be inserted. A screw seat 12 is provided on the housing 1. The connecting piece 1103 and the screw seat 12 are connected by screws to fix the radiator 11 and to make the base plate 1101 fit against the bottom of the housing.

[0025] In one embodiment of this application, preferably, an arched explosion-proof sheet 13 is fixedly installed at the bottom of the battery compartment 51. The bottom plate 1101 of the radiator 11 has a hole (not marked in the figure) for the explosion-proof sheet 13 to extend out. The fins 1102 of the radiator 11 have grooves (not marked in the figure) that are adapted to the explosion-proof sheet 13. This is used to release pressure when the battery compartment 51 catches fire or the pressure of the extinguishing gas is too high, so as to avoid explosion. The explosion-proof sheet 13 breaks under the set pressure and releases gas from the hole in the bottom plate 1101 and the gap between the fins 1102. At the same time, the radiator 11 also protects the explosion-proof sheet 13 from impact damage.

[0026] In one embodiment of this application, preferably, the bottom of the battery compartment 51 is provided with a pressure relief hole (not marked in the figure) for the explosion-proof plate 13 to extend out. A flange 14 is fixedly connected to the periphery of the pressure relief hole. The edge of the explosion-proof plate 13 is sealed and pressed between the flange 14 and the housing 1 to seal the explosion-proof plate 13 to the housing 1 and prevent water leakage from the connection of the explosion-proof plate 13.

[0027] In summary, the new energy battery box in the above embodiments of this utility model specifically includes: encapsulating the battery in the battery compartment 51 and connecting it to the management system of the management compartment 7; sealing the battery compartment 51 by fixing the box cover 4, sealing platform 3, and partition 6 with screws; connecting the functional interface 9 to the electrical equipment; a radiator 11 connected to the bottom of the box body 1; the bottom plate 1101 of the radiator 11 fitting snugly against the box body 1; an explosion-proof sheet 13 installed at the bottom of the box body 1; holes for the explosion-proof sheet 13 to extend from the bottom plate 1101 of the radiator 11; and fins 1102 having connections to the explosion-proof sheet. The 13-adaptive groove allows the explosion-proof plate 13 to break when the battery cell 51 is subjected to a certain pressure, releasing the gas inside the battery cell 51 through the gap between the fins 1102, thus preventing excessive pressure from causing an explosion. The sealing connection ring 2 at the top of the box 1 is connected to the electrical equipment, forming two seals in the new energy battery box: one is the seal at the connection between the box 1 and the electrical equipment, and the other is the seal at the box cover 4 and the sealing platform 3. At the same time, the management compartment 7 and the battery cell 51 are isolated. The functional interface 9 is set inside the box 1 to reduce the probability of water leakage and improve the waterproof performance of the new energy battery box.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
