[0002] The function of a charging pile is similar to that of a gas pump in a gas station. It can be fixed on the ground or on a wall and installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential parking lots or charging stations. It can charge various types of electric vehicles according to different voltage levels. The input end of the charging pile is directly connected to the AC power grid, and the output end is equipped with a charging plug for charging electric vehicles.

[0003] Since the wall-mounted charging pile has two heating areas, the high-voltage board and the control board, the existing heat dissipation means are to dissipate heat for the two heating areas simultaneously.

A heat dissipation mechanism 6 is arranged on the outside of the charging shell 1. The heat dissipation mechanism 6 circulates and cools the internal air of the charging shell 1 by inhaling external air, and at the same time filters the inhaled air to avoid dust clogging or even affecting the heat dissipation of the circuit board. A positioning mechanism 8 is arranged inside the charging shell 1. The positioning mechanism 8 positions the outside of the circuit board and guides the flow direction of the air to accelerate the speed of taking away the heat from the surface of the electrical component.

[0023] In this embodiment, the heat dissipation mechanism 6 includes an arc-shaped mesh plate 2, a charging cover plate 3, a side bracket 4, an air filter plate 5, and a blower 14. The back of the charging shell 1 is penetrated by the arc-shaped mesh plate 2, and the side bracket 4 is arranged directly above the charging shell 1. The air filter plate 5 is symmetrically arranged on the outside of the side bracket 4. The top of the charging shell 1 is penetrated by the blower 14, and the charging cover plate 3 is bolted to one side of the charging shell 1. The air is injected into the interior of the charging shell 1 through the blower 14 to accelerate the air flow rate.

[0024] In this embodiment, the charging shell 1 is connected to two groups of air filter plates 5 through a "U"-shaped charging cover 3 arranged at the top. One side of the charging shell 1 is sealed by the charging cover 3 to prevent external dust from being injected into the interior of the charging shell 1 along with the air.

[0025] In this embodiment, the positioning mechanism 8 includes a drainage baffle 9, a circuit backplane 10, a heat sink fin 11, a temperature sensing module 12 and a buzzer 13. The drainage baffle 9 is symmetrically arranged on both sides of the circuit backplane 10. The back of the circuit backplane 10 is provided with a heat sink fin 11. The outer side of the heat sink fin 11 is connected to the temperature sensing module 12, and the output end of the temperature sensing module 12 is connected to the buzzer 13.

[0026] In this embodiment, the circuit back plate 10 is connected to the interior of the charging housing 1 via the heat dissipation fins 11 arranged on the back, and one side of the circuit back plate 10 is suspended by the heat dissipation fins 11, which effectively accelerates the heat dissipation of the circuit back plate 10.

[0027] In this embodiment, fastening holes 15 are symmetrically formed through the outer side of the circuit back plate 10 , and the circuit board and other devices are positioned through the fastening holes 15 arranged at equal intervals.

[0028] In this embodiment, the back axis of the charging casing 1 is connected to two ends of a back bracket 16, and the back of the charging casing 1 is supported by the back bracket 16 to prevent the heat of the back of the charging casing 1 from being unable to dissipate.

[0029] This small wall-mounted charging pile includes the following work in actual application:

[0030] Step 1: The operator installs the air filter plate 5 on both sides of the side bracket 4, and turns on the blower 14, and uses the blower 14 to directly draw the outside air into the space formed by the air filter plate 5 and the side bracket 4, and directly introduces the filtered air from the outside into the charging shell 1 through the blower 14 arranged inside, and positions the charging circuit board through the charging shell 1 and connects the charging line externally, and uses the charging line to connect the power supply to provide power for the new energy vehicle. The operator can position the two sides of the charging shell 1 through the side suspension frame 7 to position the charging shell 1;

[0031] Step 2: The symmetrically arranged drainage baffles 9 are used to drain the circuit back plate 10 arranged below. The circuit back plate 10 is used to position the instrument through the fastening holes 15 arranged on the outside, and the instrument is connected to the charging cable. The heat dissipation fins 11 arranged on one side are used to position one side of the circuit back plate 10, and the heat dissipation fins 11 are used to lock the inside of the charging housing 1, and the discharged air is filtered through the arc mesh plate 2 arranged below;

[0032] Step 3: When positioning the back of the charging housing 1, the operator can pull the back bracket 16 to rotate the back bracket 16 on one side of the charging housing 1, and use the back bracket 16 to support one side of the charging housing 1. At the same time, the outer side of the back bracket 16 can be tightened by a rope, so that the charging housing 1 can be hung on a wall at a certain height;

[0033] Step 4: During the operation of the internal circuit board of the charging shell 1, the operating temperature of the device is sensed by the temperature sensing module 12. When the temperature exceeds or falls below a critical value set by the user, the buzzer 13 emits a noise to remind the user, thereby facilitating the user to disconnect the circuit of the charging pile, so that the device stops running to avoid short circuit or even damage to the device due to overtemperature.

[0034] Therefore, the embodiments disclosed above are only illustrative in all aspects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
