[0023] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0024] Reference Figure 1-6 The utility model embodiment provides an electric vehicle charging pile plug-in structure, which includes a charging pile 1, a socket 2 is provided on the charging pile 1, a protective block 3 is fixedly connected to the charging pile 1, two connecting blocks 4 are fixedly connected to the protective block 3, the inner surfaces of the two connecting blocks 4 are rotatably connected with connecting rods 5, the side surfaces of the two connecting rods 5 are fixedly connected with concave blocks 6, and the first protective door 7 and the second protective door 8 are respectively fixedly connected to the upper surfaces of the two concave blocks 6, and the outer surfaces of the two connecting rods 5 are fixedly sleeved with torsion springs 9, one end of the torsion spring 9 is fixedly connected to the connecting rod 5, and the other end of the torsion spring 9 is fixedly connected to the side inner wall of the connecting block 4, the rear surfaces of the first protective door 7 and the second protective door 8 are in contact with the protective block 3, the left surface of the first protective door 7 is in contact with the second protective door 8, the connecting rod 5 passes through the connecting block 4, and the side surface of the connecting block 4 is in contact with the concave block 6.

[0025] The front surface of the first protective door 7 is fixedly connected with an anti-slip block 10, and the inner surface of the anti-slip block 10 is rotatably connected with a limiting block 11. The front surface of the second protective door 8 is fixedly connected with an insertion rod 12, and the outer surface of the limiting block 11 is movably connected with the insertion rod 12. An anti-slip groove 13 is provided on the anti-slip block 10, and the outer surface of the limiting block 11 is rotatably connected with the anti-slip groove 13. A limiting groove 14 is provided on the insertion rod 12, and the outer surface of the limiting block 11 is movably connected with the limiting groove 14, and the anti-slip block 10 passes through the limiting block 11.

[0026] Working principle: under the action of the protective block 3, the first protective door 7 and the second protective door 8, the socket 2 on the charging pile 1 can be protected, so as to prevent rainwater from contacting the socket 2. When the socket 2 needs to be used, the limiting block 11 is rotated to make the limiting block 11 rotate with the anti-slip block 10 as the center axis. At the same time, under the action of the anti-slip groove 13, the limiting block 11 can be prevented from being separated from the anti-slip block 10. When the rotating limiting block 11 is separated from the limiting groove 14, the restriction on the torsion spring 9 is released, so that the torsion spring 9 is no longer restricted to flip and rebound, so that the flipped and rebounded torsion spring 9 drives the connecting rod 5 to rotate, so that the rotating connecting rod 5 can drive the concave block 6, the first protective door 7 and the second protective door 8 to flip with the connecting rod 5 as the center axis, so that the first protective door 7 and the second protective door 8 can be opened, exposing the socket 2 on the charging pile 1, and then the charging head can be inserted into the socket 2 for charging. When charging the electric vehicle, after the electric vehicle is charged, unplug the charging head from the socket 2, and then flip the first protective door 7 and the second protective door 8 in the opposite direction, so that the first protective door 7 and the second protective door 8 drive the recessed block 6 to flip, so that the flipped recessed block 6 drives the connecting rod 5 to rotate, so that the rotating connecting rod 5 can flip and stretch the torsion spring 9 on the inner wall of the connecting block 4, so that the torsion spring 9 is in a flipped and stretched state. When the flipped first protective door 7 and the second protective door 8 are in contact with the protective block 3, the first protective door 7 and the second protective door 8 can be made to contact at the same time, and then the limit block 11 is rotated in the opposite direction, so that the limit block 11 is rotated about the central axis of the plug rod 12. When the rotated limit block 11 is inserted into the limit groove 14 on the plug rod 12, the torsion spring 9 is restricted, so that the torsion spring 9 is always in a flipped and stretched state and will not rebound, thereby completing the fixation between the first protective door 7 and the second protective door 8, and realizing the protection of the socket 2.

Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
