The mounting seat 40 is provided with the electrical connector assembly 10, and the mounting seat 40 is movably connected with the rotating disc 30 and the connecting seat 20 through a linkage mechanism. The reset assembly is disposed on the connection base 20 and provides a force for the rotation disc 30 to switch from the loading state to the initial state. When the rotating disc 30 does not carry the battery pack, the rotating disc 30 is in the initial state under the action of the reset assembly, and the mounting seat 40 is in the initial position relative to the rotating disc 30 under the driving of the reset assembly. When the rotating disc 30 carries the battery pack, the rotating disc 30 is in a carrying state against the acting force of the reset assembly, and the mounting seat 40 is in a butting position relative to the rotating disc 30 under the driving of the linkage mechanism, so that the electrical connector assembly 10 is electrically connected with the battery end electrical connector of the battery pack.

In this embodiment, the charging connector device 100 presses the rotating disk 30 through the battery pack to enable the rotating disk 30 to rotate around the connecting end 302 thereof as a rotating point, then the overturning motion of the rotating disk 30 is converted into the motion of the mounting seat 40 close to or far away from the bearing end 301 of the rotating disk 30 through the linkage mechanism, and finally the automatic mechanical docking of the charging connector device 100 is realized, so that the electric connector assembly 10 is electrically connected with the battery pack end electric connector, and compared with the prior art, the horizontal motion of the mounting seat 40 is converted into the motion in the vertical direction to further realize the electric connection, the structure of the charging connector device 100 in the embodiment has the rotating point, and is more stable when the state switching is carried out, and the mechanical clamping stagnation is not easy to occur in the using process.

Further, in order to make the electrical connector assembly 10 float and adjust its position on the plane perpendicular to the moving direction M of the mounting base 40, so as to ensure the electrical connector assembly 10 and the battery-end electrical connector to be aligned precisely, the mounting base 40 is further provided with a vertically arranged floating plate 901, the floating plate is connected to the mounting base 40 in a floating manner through a horizontally arranged spring 902 and a vertically arranged spring 902, and the electrical connector assembly 10 is installed on the floating plate 901, that is, connected to the mounting base 40 through the floating plate 901.
