[0029] See also Figure 1-4 The main body of the automobile battery module fixing bolt of this embodiment includes: a bolt body 100, an upper metal gasket 200, a latch 300, an upper sealing structure 400, a lower metal gasket 500 and a lower sealing structure 600.

[0030] Specifically, a through hole 101 is provided on the bolt body 100 . The bolt body 100 is a hollow structure. When in use, the provision of the through hole 101 can reduce the weight of the bolt body 100 and reduce the cost.

[0031] Specifically, the upper metal gasket 200 is disposed on the bolt body 100, and is provided with two insertion holes 201 for inserting the plug 300. The two insertion holes 201 are symmetrically arranged. When in use, the upper metal gasket 200 increases the contact area, thereby helping to disperse the pressure of the bolt on the object, making the force more uniform, reducing local stress concentration, and preventing damage to the surface of the object.

[0032] Specifically, the latch 300 is inserted into the upper metal gasket 200. The latch 300 is a T-shaped column. When in use, the latch 300 can be inserted into the socket 201 of the upper metal gasket 200 and the car battery box. After insertion, it has a limiting effect to prevent the fixing bolts from loosening.

[0033] Specifically, the upper sealing structure 400 includes an upper sealing cover 401 threadedly connected to the outside of the upper metal gasket 200, and the upper sealing structure 400 also includes a first rubber pad 402 bonded to the bottom of the upper sealing cover 401. The first rubber pad 402 is ring-shaped. When in use, the upper sealing cover 401 can be aligned with the upper metal gasket 200. After alignment, the upper sealing cover 401 is rotated to fix it to the upper metal gasket 200. After fixation, the top of the fixing bolt can be sealed by the upper sealing cover 401 to prevent dust and water from contacting the top of the fixing bolt, greatly slowing down the rate of corrosion and prolonging the service life. At the same time, the first rubber pad 402 can improve the sealing effect.

[0034] Specifically, the lower metal gasket 500 is inserted into the outside of the bolt body 100, and the outside of the lower metal gasket 500 and the upper metal gasket 200 are both provided with external threads. When in use, by increasing the contact area, it helps to disperse the pressure of the bolt on the object, make the force more uniform, reduce local stress concentration, and prevent damage to the surface of the object.

[0035] Specifically, the lower sealing structure 600 includes a lower sealing cover 601 threadedly connected to the outside of the lower metal gasket 500, and the lower sealing structure 600 also includes a second rubber pad 602 bonded to the bottom of the lower sealing cover 601. The second rubber pad 602 is ring-shaped. When in use, the lower sealing cover 601 can be aligned with the lower metal gasket 500 and threadedly connected. After connection, the bottom and nut of the fixing bolt can be sealed through the lower sealing cover 601 to prevent dust and water from contacting the bottom of the fixing bolt, greatly slowing down the rate of corrosion and prolonging the service life. At the same time, the second rubber pad 602 can improve the sealing effect.

[0036] During specific use, the user can align the upper sealing cover 401 of the upper sealing structure 400 with the upper metal gasket 200, and after alignment, rotate the upper sealing cover 401 to fix it with the upper metal gasket 200. After fixation, the top of the fixing bolt can be sealed through the upper sealing cover 401 to prevent dust and water from contacting the top of the fixing bolt. Then the lower sealing cover 601 of the lower sealing structure 600 can be aligned with the lower metal gasket 500 and threadedly connected. After connection, the bottom and nut of the fixing bolt can be sealed through the lower sealing cover 601 to prevent dust and water from contacting the bottom of the fixing bolt, which greatly slows down the rate of corrosion and prolongs the service life. At the same time, the pin 300 can be inserted into the upper metal gasket 200 and the car battery box, which has a limiting effect after insertion to prevent the fixing bolt from loosening.
