[0024] like Figure 3 and Figure 4 As shown, the fixing mechanism includes a limiting groove 8, a mounting groove 9, a limiting block 10, a movable groove 11, a button 12 and a transmission groove 13. The limiting groove 8 is a groove of a rectangular structure, which is arranged on the side wall of the sealing gasket 3. The mounting groove 9 is a groove of a rectangular structure, which is arranged on the inner wall of the charging gun 1 at a position corresponding to the limiting groove 8. The limiting block 10 is a block of a trapezoidal structure, which is movably installed inside the mounting groove 9. One end of the limiting block 10 is located inside the limiting groove 8, and the limiting block 10 passes through the outer side wall of the charging gun 1. The movable groove 11 is a groove of a rectangular structure, which is arranged on the outer side wall of the charging gun 1. The button 12 is an "L"-shaped block, which is arranged on the movable groove 11. The transmission groove 13 is a groove of a rectangular structure, which is arranged on the limiting block 10. The position of the button 12 corresponds to that of the button 12, and the wall surface of one side of the button 12 corresponding to the transmission groove 13 is an inclined surface. When the cover plate 2 and the sealing gasket 3 are installed on the charging gun 1, the limit block 10 will be located inside the limit groove 8. At this time, the sealing gasket 3 will be limited by the limit block 10, and the cover plate 2 and the sealing gasket 3 cannot be removed from the charging gun 1, which is used to protect the inside of the charging gun 1. When charging is desired, only the button 12 needs to be pressed, and the button 12 moves on the charging gun 1. The transmission groove 13 provided on the limit block 10 is squeezed by the inclined surface of the button 12. After being squeezed, the transmission groove 13 moves downward, so that the limit block 10 leaves the inside of the limit groove 8. At this time, the cover plate 2 can be flipped upward by the buckle block 7, and the cover plate 2 and the sealing gasket 3 will leave the inside of the charging gun 1, and the charging operation can be performed;

[0025] The movable groove 11 is movably installed with a mounting block 14, which is a rectangular block. The mounting block 14 is connected to the button 12. The movable groove 11 is installed with a mounting spring 15, which is fixedly connected to the mounting block 14. The button 12 is movably installed on the charging gun 1 through the mounting block 14 and the mounting spring 15. When the button 12 is pressed, the mounting spring 15 is squeezed.

When the cover plate 2 and the sealing gasket 3 are moved to the interior of the charging gun 1, the sealing gasket 3 will squeeze the inclined surface of the limit block 10, so that the limit block 10 moves downward, and the limit block 10 will squeeze the installation spring 15 through the reset block 16, and then under the action of the elastic force of the installation spring 15, the limit block 10 moves to the interior of the limit groove 8, thereby fixing the sealing gasket 3.

[0026] like Figure 2 and Figure 3As shown, in one embodiment, a mounting seat 17 is fixedly mounted on the charging gun 1, and an opening is provided on the mounting seat 17, and a mounting shaft 18 is movably mounted inside the opening, and the mounting shaft 18 is a cylindrical structure, and a mounting arm 19 is movably sleeved on the mounting shaft 18, and the mounting arm 19 is a rectangular structure, and an extension arm 20 is fixedly mounted on the mounting arm 19, and the extension arm 20 is a rectangular structure, and the movable arm 4 is a hollow structure, and the extension arm 20 is movably mounted inside the movable arm 4, so that the extension arm 20 can move inside the movable arm 4, thereby changing the length of the movable arm 4 and the extension arm 20, and when the cover plate 2 is flipped upward, the movable arm 4 will also flip with the mounting shaft 18 as the base point, and at the same time, the movable arm 4 and the extension arm 20 can be retracted, so that the cover plate 2 and the sealing gasket 3 are moved away from the charging gun 1, so as to avoid the situation where the position of the cover plate 2 and the sealing gasket 3 affects the insertion of the charging gun 1 into the charging port of the vehicle.

[0027] The specific working methods are:

[0028] By providing a fixing mechanism, when the cover plate 2 and the sealing gasket 3 are installed on the charging gun 1, the limit block 10 will be located inside the limit groove 8. At this time, the sealing gasket 3 will be limited by the limit block 10, and the cover plate 2 and the sealing gasket 3 cannot be removed from the charging gun 1, which is used to protect the inside of the charging gun 1. When charging is desired, only the button 12 needs to be pressed, and the button 12 moves on the charging gun 1. The inclined surface of the button 12 squeezes the transmission groove 13 provided on the limit block 10. After being squeezed, the transmission groove 13 moves downward, so that the limit block 10 leaves the inside of the limit groove 8. At this time, the cover plate 2 can be flipped upward by the buckle block 7, and the cover plate 2 and the sealing gasket 3 will leave the inside of the charging gun 1 to perform the charging operation, thereby achieving the effect of quickly installing the cover plate 2, protecting the charging gun 1, and preventing external dust or rain from entering the inside of the charging gun 1 and causing damage to the charging gun 1.
