[0061] Some embodiments of the present invention are described in detail. In the absence of conflict, the following embodiments and features of the embodiments can be combined with each other.

[0062] Example

[0063] See also Figures 1 to 6 This embodiment provides a charging pile 100 for charging new energy vehicles.

[0064] Please refer to Figure 1 , Figure 2 , Figure 4 and Figure 5 The charging pile 100 includes a shell 110. The shell 110 includes an input control area 10, a power supply accommodating area 20 and a power output area 30. The input control area 10 and the power supply accommodating area 20 are arranged opposite to each other, and the power output area 30 is arranged at one end of the power supply accommodating area 20. The charging pile 100 also includes an input control module 40, a power supply module 50 and a power output module 60, all of which are accommodated in the shell 110. The input control area 10 is installed with an input control module 40, the power supply accommodating area 20 is installed with a power supply module 50, and the power output area 30 is installed with a power output module 60. The input control module 40 is electrically connected to the power supply module 50, and the power supply module 50 is electrically connected to the power output module 60. The power output area 30 is provided with a first channel 31, one end of which is connected to the external environment, and the first channel 31 is located on one side of the power output module 60. The input control area 10 is provided with a second channel 13, and the heat generated by the power output module 60 and the input control module 40 is conducted to the second channel 13, and the second channel 13 is located on one side of the input control module 40. The power accommodating area 20 is provided with a third channel 21, and the third channel 21 is located on one side of the power module 50. The second channel 13 is connected to the first channel 31 and the third channel 21, and the cold air flowing into the housing 110 flows into the second channel 13 through the first channel 31, takes out part of the heat of the power output area 30 and the input control area 10, and then flows out through the third channel 21. The input control module 40 is electrically connected to the mains, and is responsible for stably transmitting the alternating current obtained from the mains to the power module 50, and controlling the opening and closing of the power. The power module 50 converts the alternating current input by the input control module 40 into direct current, and transmits the direct current to the power output module 60. The power output module 60 converts the voltage of the direct current to the voltage required by the vehicle.

[0065] When the charging pile 100 is working, the multiple modules installed in each area of ​​the shell 110 will generate a lot of heat. In order to ensure that the charging pile 100 can continue to work normally, it is necessary to dissipate heat in the internal area of ​​the charging pile 100. In this embodiment, the shell 110 of the charging pile 100 is divided into three areas: the input control area 10, the power supply accommodating area 20, and the power output area 30. A second channel 13 is opened in the input control area 10, a third channel 21 is opened in the power supply accommodating area 20, and a first channel 31 is opened in the power output area 30. The cold air from the outside enters the first channel 31 and takes out the heat generated by the power output module 60 in the power output area 30. The heat generated by the power output module 60 and the input control module 40 is then conducted to the second channel 13, and the second channel 13 can take out the heat of the input control area 10. The heat conducted to the second channel 13 by the first channel 31 and the heat generated by the input control module 40 are conducted to the third channel 21 together. Finally, the heat is taken out of the power supply accommodating area 20 through the third channel 21. In this way, the charging pile 100 is designed into multiple areas, and multiple channels are designed in the multiple areas to remove heat from the multiple areas.

[0066] For details, please refer to Figure 4 and Figure 5 The housing 110 is provided with an air inlet 22 and an air outlet 23. The air inlet 22 and the air outlet 23 are located on opposite sides of the power supply accommodation area 20, and the air inlet 22 is connected to the first channel 31, the second channel 13, the third channel 21 and the air outlet 23. Cold air can enter the housing 110 from the air inlet 22, and the heat flowing from the first channel 31 and the second channel 13 to the third channel 21 flows to the outside through the air outlet 23. In this embodiment, an exhaust member 71 is also provided on the side of the power supply accommodation area 20 where the air outlet 23 is provided, and the exhaust member 71 is fixedly connected to the side of the housing 110 close to the power module 50. The exhaust member 71 discharges the heat in the power supply accommodation area 20 to the third channel 21. Under the wind force of the exhaust member 71, the heat from the first channel 31, the second channel 13 to the third channel 21 can be quickly discharged to the outside, thereby avoiding the heat accumulation in the third channel 21 and failing to be discharged to the outside in time, thereby affecting the operation of the power module 50.

[0067] In some embodiments, please also refer to Figure 3 and Figure 4The housing 110 includes a first partition 32 and a second partition 33. The first partition 32 is located between the power output area 30 and the input control area 10, and the second partition 33 is located on the side of the input control area 10 away from the power output area 30. The first partition 32 is provided with a first flow opening 321, and the second partition 33 is provided with a second flow opening 331. The first flow opening 321 connects the first channel 31 and the second channel 13, and the second flow opening 331 connects the second channel 13 and the third channel 21. The heat generated by the power output module 60 in the power output area 30 can flow into the input control area 10 through the first flow opening 321. The heat generated by the input control module 40 in the input control area 10 and the heat flowing from the first channel 31 into the second channel 13 flow into the power accommodating area 20 through the second flow opening 331. Finally, it flows to the outside through the third channel 21 in the power accommodating area 20. In this embodiment, an air inlet 72 is provided on the side of the power output area 30 close to the power output module 60. The air inlet member 72 is fixedly connected to the housing 110. The air inlet member 72 may be an air inlet fan. The air inlet member 72 is used to flow the cold air on one side of the power output area 30 into the first channel 31. The provision of the air inlet member 72 can increase the flow speed of the cold air in the power output area 30, thereby promoting the first channel 31 to quickly flow the heat generated by the power output module 60 into the second channel 13.

[0068] Further, the housing 110 further includes a third partition 34, which is located in the middle of the input control area 10, and is provided with a third flow opening 341 and a fourth flow opening 342. The third flow opening 341 and the fourth flow opening 342 are arranged at intervals. The third partition 34 divides the second channel 13 into a first air duct 131 and a second air duct 132, and the third flow opening 341 connects the first air duct 131 and the second air duct 132. The fourth flow opening 342 connects the first air duct 131, the second air duct 132 and the third channel 21. In this embodiment, the third flow opening 341 is located in the middle of the third partition 34, so that the heat in the first air duct 131 flows into the second air duct 132. The fourth flow opening 342 is located at the edge of the third partition 34, so that the cold air static fourth flow opening 342 at the air inlet 22 and / or the air outlet 23 of the power supply accommodating area 20 flows into the second air duct 132.

[0069] In this embodiment, if Figure 1As shown, the third partition 34 also divides the input control area 10 into the power input area 11 and the power control area 12. The power input area 11 is installed with the power input module 41, and the power control area 12 is installed with the power control module 42. Among them, the power input module 41 is electrically connected to the mains and the power control module 42. The power input module 41 obtains power from the mains and stably transmits the power to the power control module 42. The power control module 42 is electrically connected to the power module 50. The power control module 42 controls when power is transmitted to the power module and is responsible for the safety protection of power.

[0070] like Figure 3 and Figure 6 As shown, the first partition 32, the second partition 33 and the third partition 34 are all provided with a sliding member 80. The power output module 60 is slidably connected to the first partition 32 through the sliding member 80, the power input module 41 is slidably connected to the second partition 33 through the sliding member 80, and the power control module 42 is slidably connected to the third partition 34 through the sliding member 80. In this embodiment, the sliding member 80 includes a fixed plate 81 and a roller 82, the fixed plate 81 is fixedly connected to the first partition 32, the second partition 33 and the third partition 34, the fixed plate 81 is provided with a rolling groove (not shown), and the roller 82 is rotatably connected to the rolling groove. In this embodiment, the fixed plate 81 is also provided with a fixing hole 83, and a fastener is used to pass through the fixing hole 83 to fix the fixed plate 81 to the first partition 32, the second partition 33 and the third partition 34. Among them, the fastener can be a screw or the like. For example, when installing the power input module 41 to the power input area 11, one end of the power input module 41 can be placed on one end of the sliding member 80 of the second partition 33. Then push the power input module 41 to move in the direction close to the power input area 11, and under the push of external force, the roller 82 will rotate in the rolling groove. The rotational force of the roller 82 and the external force will jointly drive the power input module 41 to be installed in the power input area 11. In this way, the assembly steps of the power input module 41 are simplified. It can be understood that the assembly steps of the power output module 60, the power control module 42 and the power supply module 50 are the same as those of the power input module 41, and the present application will not repeat them here.

[0071] Please refer to Figure 5 , an exhaust member 71 is provided on the side of the input control area 10 close to the power supply accommodating area 20. The exhaust member 71 is fixedly connected to the input control module 40. The exhaust member 71 exhausts the wind in the input control area 10 into the third channel 21. In this embodiment, the exhaust member 71 may be an exhaust fan. The exhaust member 71 is located on the side of the power input area 11 close to the power supply accommodating area 20. Driven by the exhaust member 71, the heat in the power input area 11 is quickly transferred to the power supply accommodating area 20, and then flows to the outside through the third channel 21.

[0072] In other embodiments, the air inlet member 72 and the exhaust member 71 may both be blowers, or the air inlet member 72 may be a fan and the exhaust member 71 may be a blower. The present application does not limit the types of the air inlet member 72 and the exhaust member 71, as long as they can quickly drive the heat flow in the charging pile 100.

[0073] In this embodiment, the charging pile 100 further includes two charging guns 90. The two charging guns 90 are retractably connected to the housing 110. The two charging guns 90 are respectively arranged on opposite sides of the input control area 10, and the charging guns 90 are electrically connected to the power output module 60. The power control module 42 can respectively control the two charging guns 90 to turn on or off the charging of the vehicle.

[0074] Figures 1 to 6 The charging pile 100 shown, on the one hand, divides the housing 110 of the charging pile 100 into four areas: a power input area 11 and a power control area 12, a power supply accommodation area 20, and a power output area 30, and installs a power input module 41 in the power input area 11, a power control module 42 in the power control area 12, a power supply module 50 in the power supply accommodation area 20, and a power output module 60 in the power output area 30. In addition, a first air duct 131 is opened in the power input area 11, a second air duct 132 is opened in the power control area 12, a third channel 21 is opened in the power supply accommodation area 20, and a first channel 31 is opened in the power output area 30. The four modules generate heat in the four areas, and after the cold air from the outside enters the power output area 30 through the first channel 31, the heat flows from the second air duct 132 and the first air duct 131 to the power supply accommodation area 20, and finally flows out of the third channel 21, so as to reduce the temperature in the four areas. On the other hand, rollers 82 and rolling grooves are provided on the first partition 32, the second partition 33 and the third partition 34, so that when the power input module 41, the power control module 42, the power supply module 50 and the power output module 60 are installed in the corresponding areas, the charging pile 100 can be easily assembled under the driving force of the outside world and the rotational force of the sliding part 80, thereby reducing the complexity and cost of assembly.

[0075] The above implementation modes are only used to illustrate the technical solution of the utility model rather than to limit it.
