[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] See also Figures 1 to 4The utility model provides a technical solution: a charging plug anti-dropping device, comprising a fixed cylinder 4 rotatably matched with the charging gun 1 and a clamping block 6 fixed to the charging port 2 of the car, a clamping slot 8 is opened in the fixed cylinder 4, the clamping slot 8 corresponds to the clamping block 6, a friction block 7 is installed in the clamping slot 8, the friction block 7 corresponds to the clamping block 6, a positioning structure is installed on the charging gun 1, the positioning structure corresponds to the charging port 2 of the car, an electromagnet 13 is fixed on the charging gun 1, the electromagnet 13 corresponds to the fixed cylinder 4 and the positioning structure.

[0022] In this embodiment, a rotating plate 3 is fixed on the fixed cylinder 4, and a toggle piece 14 is fixed on one side of the rotating plate 3. The toggle piece 14 corresponds to the electromagnet 13, and the electromagnet 13 is located obliquely above the toggle piece 14. The toggle piece 14 is made of iron material.

[0023] When the electromagnet 13 is energized, it can attract the toggle piece 14, so that the toggle piece 14 rotates, and the toggle piece 14 drives the rotating plate 3 to rotate, thereby driving the fixing cylinder 4 to rotate, so that the card block 6 is inserted into the card slot 8, and the charging gun 1 is locked, thereby preventing the charging gun 1 from being unplugged during charging.

[0024] A friction ring 5 is installed on the car charging port 2, which corresponds to the fixed cylinder 4. The fixed cylinder 4 is provided with an insertion port 9, which is connected to the card slot 8. The card block 6 corresponds to the insertion port 9. The card block 6 is a C-shaped structure, and the friction block 7 is fixed to the end in the card slot 8.

[0025] Specifically, when charging is required, the charging gun 1 is inserted into the car charging port 2 so that the friction ring 5 enters the fixing cylinder 4, thereby increasing friction and preventing the charging gun 1 from falling. The card block 6 can be inserted into the card slot 8 from the insertion port 9, and then the fixing cylinder 4 is rotated so that the friction block 7 is stuck in the card block 6, thereby fixing the charging gun 1.

[0026] The positioning structure includes a positioning block 11. A positioning groove 10 is provided in the vehicle charging port 2. The positioning groove 10 corresponds to the positioning block 11. Electrode sheets 12 are fixed on the positioning block 11 and in the positioning groove 10. The electrode sheets 12 are connected to the electromagnet 13 through wires.

[0027] Insert the charging gun 1 into the car charging port 2 and the positioning block 11 into the positioning groove 10 so that the two electrode sheets 12 are in contact. Then, the electromagnet 13 is energized so that the electromagnet 13 attracts the toggle sheet 14 .

[0028] Specifically, when charging, the charging gun 1 is inserted into the car charging port 2, so that the card block 6 is inserted into the card slot 8 from the insertion port 9, and the positioning block 11 is inserted into the positioning slot 10. At this time, the charging gun 1 and the car charging port 2 are energized, and the two electrode pieces 12 are energized, and the electromagnet 13 can be energized, so that the electromagnet 13 adsorbs the toggle piece 14, and the electromagnet 13 drives the toggle piece 14 to rotate to a certain angle until the electromagnet 13 contacts the toggle piece 14. The rotation of the toggle piece 14 can drive the rotating plate 3 and the fixed cylinder 4 to rotate. At this time, the card block 6 is fixed, and the fixed cylinder 4 rotates, so that the card block 6 rotates relative to the card slot 8, so that the card block 6 contacts the end in the card slot 8. At this time, the friction block 7 is stuck in the C-shaped card block 6, and the electromagnet 13 contacts the toggle piece 14 to lock the fixed cylinder 4, and the charging gun 1 can be fixed.

[0029] When the power is turned on, the charging gun 1 is powered off. At this time, the two electrode pieces 12 are de-energized, so that the electromagnet 13 no longer attracts the toggle piece 14, and the toggle piece 14 can be toggled freely. Then the toggle piece 14 can be manually toggled, so that the toggle piece 14 drives the rotating plate 3 and the fixing cylinder 4 to reset, so that the card slot 8 no longer limits the card block 6, and the charging gun 1 can be easily pulled out.

[0030] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
