[0029] Specifically, the inner walls of the cabinet 1 and the soundproof box 2 are provided with ventilation holes, each blade surface of the electric blinds 75 is fixedly connected with a sound-absorbing sheet 76, the lower surface of the cabinet 1 is fixedly connected with two groups of symmetrical support columns 12, and the ends of the two groups of support columns 12 away from the cabinet 1 are commonly fixedly connected with a moisture-proof bottom plate 13, the bottom end of the cabinet 1 is fixedly connected with two symmetrical guide rods 14, and the ends of the two guide rods 14 away from the cabinet 1 are fixedly connected with the soundproof box 2, the outer wall of the cabinet 1 is rotatably connected with a cabinet door through a hinge, and the outer wall of the cabinet door is provided with a control panel 9, the outer wall of the cabinet 1 is fixedly connected with a mounting plate 10, and the lower surface of the mounting plate 10 is provided with two symmetrical lighting lamps 11, which can facilitate users to operate the charging pile at night through the lighting lamps 11;

[0030] Furthermore, first, part of the noise is absorbed by the sound insulation felt 71 and the sound absorbing strip 72, and the other part of the noise will be absorbed by the silencer 76 on the blade. At the same time, the vibration will be transmitted to the multiple elastic rubber blocks 74 by the support plate 5, which can further absorb the noise and buffer the vibration.

[0031] Example 2

[0032] Reference Figure 1 , 2 3 is the second embodiment of the utility model. This embodiment is based on the previous embodiment, and a heat dissipation component 8 for heat dissipation is provided on the lower surface of the ventilation plate 3;

[0033] The heat dissipation assembly 8 includes a cooling box 81 connected to the inner wall of the ventilation plate 3, the inner wall of the cooling box 81 is provided with a plurality of evenly distributed heat sinks 82, the inner wall of the bottom end of the cooling box 81 is connected with a plurality of conical ventilation pipes 83, and the inner walls on both sides of the sound insulation box 2 are fixedly connected with a plurality of heat conducting plates 84;

[0034] Specifically, a connecting plate 15 is fixedly connected to the upper surface of the cabinet 1, and a rain shield 16 is arranged on the outer wall of the connecting plate 15. The width of the rain shield 16 is greater than the width of the cabinet 1, and a solar panel is embedded in the inner wall of the rain shield 16. The fan 4, the electric shutter 75, the charging pile body 6, the lighting lamp 11 and the solar panel are all electrically connected to the control panel 9, which can prevent rainwater from entering the interior of the charging pile and prevent the electrical components inside the charging pile from being damaged.

[0035] Furthermore, the air intake ends of the two fans 4 draw the air inside the cabinet 1 into the ventilation plate 3, and the ventilation plate 3 guides the air into the cooling box 81, firstly discharges part of the heat in the air through the heat sink 82, and then cooperates with multiple conical ventilation pipes 83 to blow air into the charging pile to dissipate heat.

[0036] Working principle: When the DC charging pile is used to charge the car, the internal components of the charging pile will generate noise. First, part of the noise is absorbed by the sound insulation felt 71 and the sound absorbing strip 72. During this process, the electric shutter 75 is opened through the control panel 9, and the other part of the noise will be absorbed by the silencer 76 on the blade. At the same time, the internal components of the charging pile will vibrate when working. The vibration generated at this time will be transmitted to multiple elastic rubber blocks 74 by the support plate 5. Since the elastic rubber block 74 itself is composed of rubber, it can further absorb the noise. At the same time, it can also buffer the vibration to prevent unnecessary noise caused by large vibration amplitude. It can soundproof and reduce the noise generated by the charging pile, so that the charging pile will not cause noise pollution when charging. At the same time, it can effectively reduce noise in quiet nights or residential areas to prevent noise from affecting the quality of life of surrounding residents, thereby improving the use effect of the DC charging pile.

[0037] The charging pile will generate a lot of heat inside during the charging process. At this time, the two fans 4 are started through the control panel 9. The air intake ends of the two fans 4 draw the air inside the cabinet 1 into the ventilation plate 3, and the ventilation plate 3 guides the air to the cooling box 81. First, part of the heat in the air is discharged through the heat sink 82, and then a plurality of conical ventilation pipes 83 are used to blow air into the charging pile. The shape of the conical ventilation pipe 83 helps to dissipate heat. Since the conical ventilation pipe 83 has no sharp angles, the air can flow more smoothly and reduce wind resistance. In combination with a plurality of heat conducting plates 84, the interior of the charging pile can be effectively cooled and dissipated to prevent heat from accumulating inside the charging pile. At the same time, it can prevent heat from damaging the electronic components inside the charging pile, thereby increasing the service life of the DC charging pile.
