[0007] As a preferred solution, the gear is installed in the mounting cavity inside the two sides of the charging base, one side of the gear extends into the charging socket, and is meshed with the rack slider for transmission connection.

[0008] As a preferred solution, the locking rod is driven to move horizontally and telescopically in the limiting cylinder by the repulsive force generated by the first electromagnet and the second electromagnet when they are energized.

[0009] As a preferred solution, sliding grooves are provided on both sides of the inner wall of the charging socket, and the charging plug slides into the charging socket through the sliding grooves via a rack slider.

After plugging in, connect and power on for charging; during charging, the first electromagnet 36 and the second electromagnet 37 inside the electromagnet device start to be energized and magnetized, and a mutual repulsive force is generated between the first electromagnet 34 and the second electromagnet 35, which drives the locking rod 32 to move toward the gear in the limit cylinder 31 through the repulsive force, compressing the spring 35, so that the locking rod 32 drives the locking block 33 to be locked in the gear 2, preventing the gear 2 from rotating during charging; the charging plug 1 is fixed by the locking mechanism 3, and the charging plug 1 can be directly fixed during charging without performing unnecessary operations, thereby preventing the charging gun from loosening during charging; the charging efficiency and safety are improved.

[0027] In this embodiment, the gear 2 is installed in the mounting cavity inside both sides of the charging seat 4, and one side of the gear 2 extends into the charging socket 5 and is meshed with the rack slider 12 for transmission connection; grooves 51 are provided on both sides of the inner wall of the charging socket 5, and the charging plug 1 slides into the charging socket 5 through the rack slider 12 through the groove 51; pick up the charging plug 1 by grasping the handle 11, align the charging plug 1 with the charging socket 5 of the charging seat 4, and make the rack sliders 12 on both sides of the charging plug 1 slide into the charging socket 5 along the grooves 51 on both sides of the inner wall of the charging socket 5.
