[0002] A DC charging gun is an essential component of electric vehicle charging stations. It uses direct current (DC) to rapidly charge an electric vehicle's power battery. Compared to AC charging guns, DC charging guns offer higher charging power, resulting in faster charging speeds. DC charging guns are commonly used in public charging stations or large commercial facilities, such as shopping malls and parking lots, to meet user demands for fast charging.

[0003] According to the Chinese patent announcement number: CN208559061U, a heat sink for a DC charging gun includes a base and a cover. The cover is mounted on one end of the base, and the other end is used to connect to the gun body of the DC charging gun, and the base is provided with a plurality of through holes; a pin is passed through each of the through holes, one end of the pin is connected to the DC charging gun socket as a charging end, and the other end is connected to the power cord as a power supply end; a heat dissipation device is mounted on the outside of the power supply end, and a plurality of heat dissipation holes are provided on the cover relative to the heat dissipation device.

[0004] In the above solution, multiple heat dissipation holes are opened to reduce the temperature of the terminal, but it still has the following disadvantages: the heat dissipation effect on the terminal is poor and the heat dissipation effect is not obvious because the heat dissipation holes are only used to passively wait for the heat to dissipate into the air. Utility Model Content

[0005] The purpose of the utility model is to provide an air-cooled DC gun to solve the problem that only heat dissipation holes are used to passively wait for heat to be dissipated in the air, resulting in poor heat dissipation effect on the terminal and unclear heat dissipation effect.

[0006] In order to achieve the above-mentioned purpose of the utility model, the utility model adopts the following technical solutions: an air-cooled DC gun, comprising a main shell, a stopper fixed inside the main shell, two DC terminals fixedly inserted on the stopper, a blocking plate fixed on one side of the stopper, a plurality of heat sinks fixed on the stopper, a sealing thermal conductive adhesive is filled between the DC terminals and the heat sinks, a plurality of heat sinks are equidistantly distributed on the stopper, a sliding folding plate is detachably provided on the main shell, a cooling fan is provided inside the sliding folding plate, the cooling fan is directly below the plurality of heat sinks, and a plurality of ventilation holes are provided on the surface of the main shell.

[0007] Preferably, a plug is provided on one side of the main shell, and two jacks are opened on one side of the plug, and the jacks are fixedly inserted into the DC terminal. A connecting shell is provided on the end of the main shell away from the plug, and a cable is fixedly inserted into the connecting shell, and one end of the cable is fixed to one end of the DC terminal.

[0008] Preferably, a handle shell is fixed between the main shell and the connecting shell, and a gripping opening is provided on the handle shell.

[0009] Preferably, a fixed folding plate is fixed on the surface of the main shell, and sliding grooves are respectively provided on both sides of the interior of the sliding folding plate. The fixed folding plate and the sliding grooves are slidably matched, and a plurality of ventilation holes are provided on the bottom surface of the sliding folding plate. A rotating hole is provided on the bottom surface of the sliding folding plate, and a limiting bolt is provided for rotation inside the rotating hole.

[0010] Preferably, a mounting groove is provided on the top surface of the main shell, a rotating rod is fixed inside the mounting groove, a rotating plate is rotatably provided on the rotating rod, a limiting strip is fixed on the bottom surface of the rotating plate, a fixing cylinder is fixed on the inner bottom surface of the mounting groove, a spring is fixed on the inner bottom surface of the fixing cylinder, and the other end of the spring is fixed to the bottom surface of the rotating plate.

[0011] Preferably, a fixed plate is fixed on the top surface of the rotating plate, and a plurality of anti-slip points are fixed on the top surface of the fixed plate.

[0012] Compared with the prior art, an air-cooled DC gun adopting the above technical solution has the following beneficial effects:

[0013] 1. The staff can lift the handle shell by holding the inner part of the grip, and then lift the main shell, plug and connection shell, and then insert the plug into the charging port. The thermal adhesive between the heat sink and the DC terminal can play the role of thermal insulation. As charging progresses, the temperature of the DC terminal will increase and transfer the heat to the heat sink through the thermal adhesive. At this time, the staff will start the cooling fan. The airflow generated by the cooling fan will pass through multiple heat sinks and dissipate the heat into the air. The cooling fan circulates back and forth to reduce the temperature of the DC terminal, thereby increasing the cooling effect of the DC terminal.

[0014] Second, when the cooling fan fails and needs to be replaced, the staff will first unscrew the limit bolt from the rotating hole, and then apply a lateral force to the sliding flap to separate the sliding flap and the fixed flap, thus exposing the cooling fan to the external environment, thereby increasing the convenience of the staff in repairing the cooling fan;

[0015] 3. When the staff pulls out the plug from the charging port, they will first press down the fixed plate, and then press down one end of the rotating plate. At this time, one end of the limit strip installed on the bottom of the rotating plate will rise, and then the plug can be pulled out. When the staff inserts the plug into the charging port, the rotating plate will also enter the charging port. At this time, the limit strip on the bottom of the rotating plate will be stuck in the charging port, which can increase the firmness of the plug in the charging port.

[0023] During use, the staff can lift the handle shell 10 by holding the inside of the gripping port 11, and then lift the main shell 1, plug 8 and connecting shell 12, and then insert the plug 8 into the charging port. The thermal conductive glue between the heat sink 5 and the DC terminal 3 can play the role of thermal insulation. As the charging progresses, the temperature of the DC terminal 3 will increase, and the heat will be transferred to the heat sink 5 through the thermal conductive glue. At this time, the staff starts the cooling fan 6. The airflow generated by the cooling fan 6 when it is working will pass through multiple heat sinks 5, and the heat can be dissipated into the air.

[0025] During use, when the cooling fan 6 fails and needs to be replaced, the staff will first unscrew the limit bolt 18 from the rotating hole 17, and then apply a lateral force to the sliding folding plate 7 to separate the sliding folding plate 7 and the fixed folding plate 14, thereby exposing the cooling fan 6 to the external environment, thereby increasing the convenience of the staff in repairing the cooling fan 6.

[0026] like Figure 2 and Figure 3As shown, a mounting groove 19 is provided on the top surface of the main shell 1, and a rotating rod 20 is fixed inside the mounting groove 19.
