[0102] In some embodiments of the present application, the recess 41 is provided with a heat conducting material.

[0103] In this way, the heat conducting material arranged in the recess 41 can improve the heat conduction efficiency of the heat conducting member 40 and the cooling assembly 30, and further improve the cooling efficiency of the cooling assembly 30, so as to reduce the temperature of the charging terminal 20.

[0104] In some embodiments of the present application, the heat conducting material is heat conducting silica gel or heat conducting silicone grease.

[0105] Thus, the heat-conductive silica gel or heat-conductive silicone grease can be injected into the avoiding groove 41, so that the heat-conductive silica gel or heat-conductive silicone grease fills the avoiding groove 41, which not only improves the heat-conducting efficiency of the heat-conducting member 40 and the cooling assembly 30, but also makes the processing more convenient.

[0106] In some embodiments of the present application, as shown in Figure 1 , Figure 2 and Figure 3 , the at least one charging terminal 20 includes a first charging terminal 21 and a second charging terminal 22; the at least one cooling assembly 30 includes a first cooling assembly 37 and a second cooling assembly 38; and the at least one heat-conducting member 40 includes a first heat-conducting member 42 and a second heat-conducting member 43; the first heat-conducting member 42 is in thermal conduction with the first cooling assembly 37 and the first charging terminal 21, and the second heat-conducting member 43 is in thermal conduction with the second cooling assembly 38 and the second charging terminal 22.

[0107] Thus, the first cooling assembly 37 and the second cooling assembly 38 are in thermal conduction with the first charging terminal 21 and the second charging terminal 22, respectively, so that the first charging terminal 21 and the second charging terminal 22 in the charging gun 100 can be cooled, and the damage of the charging gun 100 caused by the excessively high temperature of one of the charging terminals 20 can be avoided.

[0108] In some embodiments of the present application, as shown in Figure 1 , Figure 2 and Figure 3 , the first cooling assembly 37 is arranged on one side of the first heat-conducting member 42 facing the second heat-conducting member 43; and the second cooling assembly 38 is arranged on one side of the second heat-conducting member 43 facing the first heat-conducting member 42.

[0109] Thus, the first cooling assembly 37 and the second cooling assembly 38 are both arranged between the first cooling assembly 37 and the second charging terminal 22, so that the distance between the first charging terminal 21 and the second charging terminal 22 can be increased, and the short circuit between the first charging terminal 21 and the second charging terminal 22 and the damage of the charging gun 100 can be avoided.

[0110] In some embodiments of the present application, the first cooling assembly 37 can be arranged on one side of the first heat-conducting member 42 away from the second heat-conducting member 43; and the second cooling assembly 38 can be arranged on one side of the second heat-conducting member 43 away from the first heat-conducting member 42.

[0111] Thus, the first cooling assembly 37 is arranged on the outside of the first heat-conducting member 42, and the second cooling assembly 38 is arranged on the outside of the second heat-conducting member 43, which facilitates the installation of the first cooling assembly 37 and the second cooling assembly 38.

[0112] In some embodiments of the present application, as shown in Figure 1 , Figure 2and Figure 7 As shown in the figure, the charging gun 100 further comprises at least one temperature detection assembly 60 adapted to detect the temperature of the charging terminal 20, the temperature detection assembly 60 comprising a detection piece 61 at least partially arranged in the charging terminal 20.

[0113] In this way, the temperature of the charging terminal 20 can be detected by the temperature detection assembly 60, and the cooling assembly 30 can be adjusted according to the detection result, so as to avoid the overcooling or overheating of the charging terminal 20, and ensure the normal work of the charging terminal 20.

[0114] The above is only a specific implementation manner of the present application, but the protection scope of the present application is not limited to this, any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
