[0025] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0026] like Figure 1 to Figure 2 As shown, in one embodiment of the present application, the charging pile includes a housing 11, a PCB board 12, a heat dissipation fan 13 and a drive assembly 14.

[0027] The interior of the housing 11 is configured to be hollow.

[0028] The PCB board 12 is disposed inside the housing 11 , and the PCB board 12 is fixedly connected to the housing 11 .

[0029] The heat dissipation fan 13 is arranged on one side of the PCB board 12, and the heat dissipation fan 13 is rotatably connected to the shell 11. When in use, the heat dissipation fan 13 drives the airflow outside the shell 11 to blow toward the PCB board 12 inside the shell 11, so that the heat generated by the PCB board 12 is taken away by the airflow.

[0030] The driving assembly 14 is disposed inside the housing 11 . The driving assembly 14 is fixedly connected to the housing 11 . The driving assembly 14 is used to drive the heat dissipation fan 13 to swing back and forth.

[0031] Specifically, the PCB board 12 is suspended inside the housing 11 , and the PCB board 12 is arranged in a square shape. The four corners of the PCB board 12 are fixedly connected to the housing 11 through a positioning bolt respectively.

[0032] In this embodiment, by first starting the heat dissipation fan 13, the heat dissipation fan 13 will accelerate the airflow outside the shell 11 and bring it into the interior of the shell 11. When the airflow enters the interior of the shell 11, it will blow toward the PCB board 12, and take away the heat generated on the PCB board 12, so that the temperature of the PCB board 12 is maintained at a normal operating temperature. Then, the driving component 14 is started, and the driving component 14 will drive the heat dissipation fan 13 to swing back and forth along a certain swing amplitude, so that the airflow will blow in multiple directions when entering the interior of the shell 11, further making the heat dissipation of multiple parts on the PCB board 12 uniform, thereby improving the heat dissipation efficiency.

[0033] like Figure 2 to Figure 3 As shown, in one embodiment of the present application, the housing 11 includes a first shell 111 , a second shell 112 and a hinge 113 .

[0041] In this embodiment, the first vent 111a is disposed on one side of the PCB board 12, and the heat dissipation fan 13 is disposed in the first vent 111a, so that the airflow outside the housing 11 passing through the heat dissipation fan 13 can directly impact the PCB board 12, thereby taking away the heat generated by the PCB board 12.

[0042] like Figure 4 As shown, in one embodiment of the present application, the driving assembly 14 includes a first matching plate 141 , a second matching plate 142 , an adapter frame 143 and a driving member 144 .

[0056] The driving member 144 includes a driving disk 144a, a driving rod 144b and a power motor 144c.

[0061] Specifically, the driving rod 144 b is disposed on a side of the driving disk 144 a close to the second connecting plate 17 , and the driving rod 144 b is slidably connected to the first positioning groove 18 .

[0062] In this embodiment, by starting the power motor 144c, the power motor 144c drives the driving disk 144a to rotate, and then drives the driving rod 144b to rotate around the axis of the driving disk 144a. During the process of the driving rod 144b rotating around the axis of the driving disk 144a, the driving rod 144b will synchronously drive the second connecting plate 17 to move back and forth. At the same time, the reciprocating movement of the second connecting plate 17 drives the reciprocating movement of the first connecting plate 16. The reciprocating movement of the first connecting plate 16 will synchronously drive the first matching plate 141 to rotate through the first adapter shaft 143a, and synchronously drive the second matching plate 142 to rotate through the second adapter shaft 143b, thereby realizing the reciprocating swing of the heat dissipation fan 13.
