[0025] The protective component 4 includes a protective shell 401, a sealing gasket 402 at the port of the protective shell 401, a mounting post 403 fixedly connected to the inner wall of the protective shell 401, a sliding groove 404 provided on the inner wall of the mounting post 403, a sliding rod 405 slidably connected to the inner wall of the sliding groove 404, a return spring 406 installed at one end of the sliding rod 405 inside the sliding groove 404, and a silicone plate 407 fixedly connected to the end of the sliding rod 405 away from the return spring 406. An installation component 5 is disposed inside the protective shell 401. The protective component 4 protects the battery charging port in the charging shell 1, preventing paint from entering the charging interface.

[0026] Mounting assembly 5 includes an adjusting shell 501 fixedly connected to the inner wall of the protective shell 401, and the adjusting shell 501 is located between the protective shell 403 and the silicone plate 407. A bidirectional lead screw 502 is rotatably connected to the inner wall of the adjusting shell 501, and a worm gear 503 is fixedly connected to the outer wall of the bidirectional lead screw 502. Threaded sleeves 504 are sleeved on the outer wall of the bidirectional lead screw 502 on both sides of the worm gear 503. Mounting rods 505 are fixedly connected to the opposite sides of the two threaded sleeves 504. A worm gear 506 is rotatably connected to the inner wall of the adjusting shell 501. Mounting assembly 5 facilitates the installation of the protective shell 401 into the charging shell 1.

[0027] A knob 5061 is fixedly connected to one end of the worm gear 506 that passes through the adjusting housing 501 and the protective housing 401. The operator can directly rotate the knob 5061 to adjust the position of the mounting rod 505.

[0028] One side of the adjusting shell 501 and the protective shell 401 has a through hole 6 adapted to the mounting rod 505. The mounting rod 505 passes through the through hole 6 and is slidably connected to the mounting hole 3. The mounting rod 505 is slidably connected to the mounting hole 3 of the charging shell 1 through the through hole 6, so as to firmly fix the protective component 4 and prevent displacement during the painting process.

[0029] The worm 506 is located on one side of the worm wheel 503, and its outer wall is connected to the outer wall of the worm wheel 503 via a transmission connection. The meshing transmission between the worm 506 and the worm wheel 503 ensures the stability of the adjusted mounting rod 505.
