Multiple groups of mounting bolts 8 are provided inside the multiple groups of first screw holes 5 and second screw holes 7. An air injection pipe 9 is provided on one side wall of the first cover body 2, and an exhaust pipe 10 is provided on one side of the air injection pipe 9. The exhaust pipe 10 is provided on the side wall of the first cover body 2. The diameters of the first screw hole 5 and the second screw hole 7 are the same, and the first screw hole 5 and the second screw hole 7 are used in conjunction with the mounting bolts 8. A deoxidizer layer is provided on the inner surfaces of the first cover body 2 and the second cover body 3.

[0020] Specifically, the second screw hole 7 is arranged directly above the first screw hole 5, and the mounting bolt 8 is installed inside the first screw hole 5 and the second screw hole 7, so that the battery assembly 1 can be installed inside the first cover body 2 and the second cover body 3; gas other than oxygen is injected into the first cover body 2 and the second cover body 3 through the gas injection pipe 9, and the air existing in the first cover body 2 and the second cover body 3 is discharged, so that the battery assembly 1 can be arranged inside the first cover body 2 and the second cover body 3, and the battery assembly 1 can be placed in an oxygen-free state. At the same time, the deoxidizer layer 17 can further deoxidize the interior of the first cover body 2 and the second cover body 3, thereby increasing the possibility of avoiding fire of the battery assembly 1.

[0021] like Figure 1-Figure 2 As shown, two groups of support blocks 11 are arranged on the front and rear end walls of the second cover body 3, a group of limit blocks 12 are arranged on the upper end surfaces of the multiple groups of support blocks 11, and a group of limit frames 13 are arranged on the upper ends of the multiple groups of limit blocks 12; the multiple groups of limit frames 13 are respectively arranged on the front and rear end walls of the first cover body 2; by setting the limit blocks 12 and the limit frames 13, the first cover body 2 can be limited to the upper end of the second cover body 3, so as to facilitate the fixing of the first cover body 2 and the second cover body 3.

[0022] like Figure 1-Figure 4As shown, the inner surfaces of the first cover body and the second cover body are provided with a deoxidizer layer, both of which include a base plate 14, and multiple groups of inner walls of the base plate 14 are provided with frame plates 15; multiple groups of frame plates 15 are provided with multiple groups of grooves 16, and multiple groups of grooves 16 are provided with a group of deoxidizer layers 17 inside, and multiple groups of deoxidizer layers 17 are arranged on the side walls of the base plate 14; the deoxidizer layer 17 is made of deoxidizer, which is also made of deoxidizer thermal insulation material, which belongs to existing materials and is currently mostly used for deoxidation and preservation of food. When there is still a surplus or leakage in the internal oxygen content of the first cover body 2 and the second cover body 3, multiple groups of deoxidizer layers 17 are used to remove the oxygen in the first cover body 2 and the second cover body 3, which is relatively practical.

[0023] The above embodiment discloses a deoxygenated battery cover. When in use, the battery assembly 1 is placed inside the first cover body 2 and the second cover body 3. Then, the first cover body 2 can be limited to the upper end of the second cover body 3 by the limit block 12 and the limit frame 13, so that the second screw hole 7 is set just above the first screw hole 5. Then, the mounting bolt 8 is installed inside the first screw hole 5 and the second screw hole 7, so that the battery assembly 1 can be installed inside the first cover body 2 and the second cover body 3; the first cover body 2 and the second cover body 3 are filled with gas other than oxygen through the gas injection pipe 9 connected to the external gas pipe, and the air existing in the first cover body 2 and the second cover body 3 is discharged. When actually exhausting, a nitrogen gas injection device can be used, and the first cover body 2 and the second cover body 3 are filled with only nitrogen gas, thereby making them oxygen-free; when the internal oxygen content of the first cover body 2 and the second cover body 3 still has a surplus or leaks, multiple groups of deoxygenating agent layers 17 are continuously used to remove the oxygen in the first cover body 2 and the second cover body 3, which is relatively practical. The externally connected gas injection device is not described in detail. The existing gas injection device can be used to inject gas and exhaust oxygen. After the gas is injected and exhausted, the gas injection pipe 9 and the exhaust pipe 10 can be blocked.

[0024] The present invention effectively realizes a deoxygenating battery cover. By arranging a cover-type deoxygenating assembly, arranging an air injection pipe, an exhaust pipe, and a positioning block, the battery assembly is effectively arranged inside a first cover and a second cover. The battery assembly is placed in an oxygen-free state by performing an air injection and oxygen exhaust operation. Meanwhile, the deoxygenating agent layer can further continuously perform an oxygen-free operation on the inside of the first cover and the second cover, thereby ensuring that the automobile battery remains in an oxygen-free state during installation and use, thereby increasing the possibility of avoiding fire of the internal battery assembly after installation and use.

[0025] The oxygen-free battery with the oxygen-free battery cover is also a deoxygenated battery structure for automobiles.
