It should be understood that the numbers used in this way can be interchanged where appropriate, so as to describe the embodiments of the present application described herein.

[0037] In the present application, the terms "upper", "lower", "left", "right", "front", "back", "top", "bottom", "inside", "outside", "middle", "vertical", "horizontal", "lateral", "longitudinal" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. These terms are mainly intended to better describe the present application and its embodiments, and are not intended to limit the indicated devices, elements or components to have a specific orientation, or to be constructed and operated in a specific orientation. Moreover, in addition to being used to indicate orientation or positional relationships, some of the above terms may also be used to express other meanings. For example, the term "upper" may also be used to indicate a certain dependency or connection relationship in some cases. For those of ordinary skill in the art, the specific meanings of these terms in the present application can be understood according to the specific circumstances.

[0038] like Figure 1 As shown, this embodiment provides a transport box for batteries, including a box cover 100 and a box body 200, the box body 200 and the box cover 100 are detachably connected, a sealing member is provided between the box body 200 and the box cover 100, and the top of the box body 200 is sealed by the box cover 100 through the sealing member. Optionally, the sealing member is a sealing strip made of rubber, rubber plastic and other materials, so that the explosion-proof box has good sealing performance during transportation.

[0039] like Figure 2As shown, a first cavity 100a is formed inside the box cover 100, and the first cavity 100a is filled with granular fire extinguishing materials. A second cavity 200a is formed inside the box body 200, and the second cavity 200a is filled with granular fire extinguishing materials. Optionally, the fire extinguishing material is made of granular gravel, perlite, vitrified microspheres and other materials. The space formed between the first cavity 100a and the second cavity 200a is used to place batteries. In this way, after the battery is placed in the explosion-proof box, it can be fully surrounded by the fire extinguishing material. When the battery burns and catches fire, the granular fire extinguishing material can absorb heat and smoke, thereby playing a role in cooling and achieving the purpose of explosion and fire prevention. Even when the battery burns, the granular fire extinguishing material in the first cavity 100a can fall into the box body 200 to cover the battery, so as to better achieve the purpose of fire extinguishing.

[0040] Specifically, combined Figure 2 and Figure 3 The box cover 100 includes a detachably connected upper cover 110 and a lower cover 120, a first cavity 100a is formed between the upper cover 110 and the lower cover 120, and at least a part of the lower cover 120 is provided with air holes 600, for example, the bottom surface and the side surface of the lower cover 120 can be both provided with air holes 600, and the air holes 600 can be circular, rectangular or other shapes. Therefore, since the granular fire extinguishing material has irregular gaps, in the early stage of battery combustion, the fire extinguishing material can absorb the heat and smoke generated by the battery through the air holes 600, play a cooling role, and further prevent the battery from exploding.

[0041] More specifically, combined Figure 2 and Figure 4 The box body 200 includes an outer box body 210 and an inner box body 220, and a second cavity 200a is formed between the inner box body 220 and the outer box body 210; at least a part of the inner box body 220 is provided with air holes 600 to further reduce the risk of battery explosion.

[0042] The box cover 100 and the box body 200 each include a plurality of split structure designs, which are detachably connected to each other, making the explosion-proof box easy to assemble, and the fire extinguishing particles can be quickly filled into the first cavity 100a and the second cavity 200a, and it is also convenient for users to perform subsequent inspection and maintenance. The "detachably connected" means that the split structures can be connected by threads, snaps, or hooks, etc., which will not be described in detail in this embodiment.

[0043] Furthermore, the diameter of the air hole 600 is smaller than the diameter of the fire extinguishing material, so as to prevent the fire extinguishing material from leaking out of the air hole 600 .

[0044] As another optional solution, the diameter of the air hole 600 can also be larger than the fire extinguishing material. However, in this case, a layer of fine-mesh steel mesh is required on the lower cover 120 and then the granular fire extinguishing material is loaded. The steel mesh is used to further prevent the fire extinguishing material from leaking out.

[0045] Preferably, the fire extinguishing material is wrapped by a fabric, such as a mesh bag or a cloth bag, so that when the battery burns, the medium that blocks the fire extinguishing material can be burned in time, so that the granular fire extinguishing material in the first cavity 100a falls into the second box body 200 more quickly from the air vent 600, thereby covering the battery and achieving the fire extinguishing function more efficiently.

[0046] Specifically, Figure 2 , Figure 4 , Figure 5 As shown, the inner box 220 is provided with an outwardly extending edge 221 around its opening, and the outer box 210 is connected or abutted against the legs 222 and the edge 221, and the inner box 220 closes the opening of the outer box 210 to a certain extent. More specifically, as an optional solution, the side wall of the inner box 220 can be flush with the side wall of the outer box 210; as another optional solution, the side wall of the inner box 220 can be lower than the side wall of the outer box 210, and when the box cover 100 closes the box 200, the lower cover 120 extends into the outer box 120 and is located above the inner box 220.

[0047] Specifically, the bottom surface of the inner box body 220 is provided with supporting legs 222 . The supporting legs 222 are plate-shaped or column-shaped, and there may be a plurality of supporting legs 222 , so as to effectively support the inner box body 220 .

[0048] Further, see Figure 4 , 5 As shown, the edge 221 is provided with a hole or a notch, which can facilitate the user to take the inner box 220 out of or put it into the outer box 210, and the user can also fill the granular fire extinguishing material through the hole or the notch.

[0049] Among them, refer to Figure 1 , Figure 6 A first limiting member 130 is provided on the top surface of the box cover 100, and a second limiting member 230 is provided on the bottom surface of the box body 200. The first limiting member 130 and the second limiting member 230 are adapted in shape and can be engaged with each other, so that the explosion-proof boxes will not shift or fall when stacked together.

[0050] Specifically, the cross section of the first limiting member 130 is in a ┌ shape, the second limiting member 230 is in a rectangular shape, and the first limiting member 130 can fit two adjacent side surfaces of the second limiting member 230 .

[0051] Specifically, refer to Figure 1 , Figure 6One side of the box body 200 is rotatably connected to the box cover 100 through the hinge 300, and the box cover 100 is connected to the box body 200 through the buckling structure 400 on the side opposite to the hinge 300. Specifically, the movable component of the buckling structure 400 is rod-shaped. Furthermore, the hinge 300 is equipped with a torsion spring, making it easier to open the box cover 100.

[0052] Specifically, refer to Figure 1 , Figure 6 A handle 700 is provided on the top of the box cover 100 to further facilitate the user to operate the box cover 100.

[0053] Preferably, Figure 7 , 8 As shown, a support device 500 is arranged between the box body 200 and the box cover 100, and the support device 500 includes a buckle 510 and a support rod 520, and the buckle 510 is installed on the outer wall of the box body 200. One end of the support rod 520 is hinged to the box cover 100, and the other end of the support rod 520 is provided with a limiting groove 521. When the box cover 100 is separated from the box cover 100, the buckle 510 can be inserted into the limiting groove 521, so that the support device 500 limits the relative movement of the box body 200 and the box cover 100. Specifically, the limiting groove 521 is T-shaped. This design can ensure the lightweight of the explosion-proof box as much as possible, and is easy to transport, while making it convenient for users to take the battery.

[0054] More specifically, when the box cover 100 closes the box body 200, the support rod 520 is inserted into the buckle 510 to limit the swing of the support rod 520 and prevent noise during transportation. The buckle 510 can guide the movement direction of the support rod 520 when the explosion-proof box is subsequently opened, so that the limit groove 521 is accurately engaged with the buckle 510.
