[0033] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0034] like Figure 1 The image shows an embodiment of a charging pile according to the present invention. Figure 1The embodiment of a charging pile of the present invention shown includes: a cabinet 100, a first cavity 110, a second cavity 120, and a third cavity 130 disposed within the cabinet 100; wherein the second cavity 120 is used to house the power module 410 of the charging pile, and the third cavity 130 is used to house the control module 420 of the charging pile; and a first air duct opening (not shown in the figure) and a second air duct opening 220 disposed between the first cavity 110 and the second cavity 120, and a third air duct opening (not shown in the figure) and a fourth air duct opening 240 disposed between the second cavity 120 and the third cavity 130; When the charging pile is in heating mode, the first air duct, the second air duct 220, the third air duct, and the fourth air duct 240 are set to the open state. The first cavity 110, the second cavity 120, and the third cavity 130 form an open heating air duct through the open first air duct, the second air duct 220, the third air duct, and the fourth air duct 240. When the charging pile is in cooling mode, the first air duct, the second air duct 220, the third air duct, and the fourth air duct 240 are set to the closed state. The heating air duct is closed when the first air duct, the second air duct 220, the third air duct, and the fourth air duct 240 are closed.

[0035] Specifically, based on the layout of the various working modules in the cabinet 100, the cabinet 100 is divided into cavities to obtain a first cavity 110, a second cavity 120, and a third cavity 130. The cavities are isolated by partitions. Each cavity is designed to house its corresponding working module. A first air duct opening (not shown in the figure) and a second air duct opening 220 are provided between the first cavity 110 and the second cavity 120. A third air duct opening (not shown in the figure) and a fourth air duct opening 240 are provided between the second cavity 120 and the third cavity 130. When the charging station is in a low-temperature environment and needs to enter heating mode, the air in the first cavity 110, the second cavity 120, and the third cavity 130 can flow through the heating air ducts formed by the first air duct opening, the second air duct opening 220, the third air duct opening, and the fourth air duct opening 240 to heat the interior of the cabinet. In this embodiment, the airflow directions of the first and second air duct openings 220 are opposite. For example, if air in the second cavity 120 can enter the first cavity 110 through the first air duct opening, then air in the first cavity 110 needs to enter the second cavity 120 through the second air duct opening 220. Similarly, air in the second cavity 120 can enter the third cavity 130 through the third air duct opening, while air in the third cavity 130 needs to enter the second cavity 120 through the fourth air duct opening 240. In another embodiment, the airflow directions can also be reversed. The state of the heating air duct can be controlled by setting the first, second, third, and fourth air duct openings 240 to be open or closed. For example, when the first, second, third, and fourth air duct openings 220, and 240 are closed, the corresponding airflow channels are cut off, and the heating air duct is in a closed state. When the first air duct, the second air duct 220, the third air duct, and the fourth air duct 240 are all open, the corresponding air circulation channels are opened, and the heating channel can then be used for air circulation; the heating channel is in the open state. Heating the cabinet 100 through the heating channel ensures the normal start-up and use of the charging cabinet even in low-temperature environments.

[0036] The operating mode of the charging station can be adjusted as needed. For example, adjustment rules or trigger conditions can be set to set the charging station's heating or cooling mode according to the set rules or trigger conditions.

[0037] Optionally, the first and third air duct openings are arranged along one diagonal of the second cavity 120; the second air duct opening 220 and the fourth air duct opening 240 are arranged along the other diagonal of the second cavity 120. Specifically, to maximize the circulation of the heating air duct within the cabinet 100, the first and third air duct openings, as well as the second and fourth air duct openings 220 and 240, can be arranged diagonally. It can be understood that the airflow directions corresponding to the first and third air duct openings are the same, and the airflow directions corresponding to the second and fourth air duct openings 220 and 240 are the same. To ensure sufficient airflow within the larger space of the cabinet 100, the distance between the first and third air duct openings, and the distance between the second and fourth air duct openings 220 and 240, should be as large as possible. Meanwhile, the airflow directions corresponding to the first air duct opening and the second air duct opening 220 are opposite, and the airflow directions corresponding to the third air duct opening and the fourth air duct opening 240 are also opposite. In order to reduce the mutual influence between the first air duct opening and the second air duct opening 220, and between the third air duct opening and the fourth air duct opening 240, the distance between the first air duct opening and the second air duct opening 220 and the distance between the third air duct opening and the fourth air duct opening 240 are set as large as possible.

[0038] In one embodiment, the second air duct opening 220 includes a first baffle 221, which controls the opening and closing of the second air duct opening 220. Specifically, a first baffle 221 can be provided corresponding to the second air duct opening 220, and the second air duct opening 220 can be opened or closed by controlling the position of the first baffle 221. In one embodiment, the first baffle 221 can also be other blocking structures and controlled by a solenoid valve to block or remove the blockage of the second air duct opening 220.

[0039] In one embodiment, the fourth air duct opening 240 includes a second baffle 241, which controls the opening or closing of the fourth air duct opening 240. Specifically, a second baffle 241 corresponding to the fourth air duct opening 240 can be provided, and the fourth air duct opening 240 can be opened or closed by controlling the position of the second baffle 241. In one embodiment, the second baffle 241 can also be other blocking structures and controlled by a solenoid valve to block or remove the blockage of the fourth air duct opening 240.

[0040] like Figure 1 As shown, this is the open state of the heating air duct, in which the first baffle 221 and the second baffle 241 are open. Figure 2 As shown, the heating air duct is in the closed state, at which time the first baffle 221 and the second baffle 241 are in the closed state.

[0041] In one embodiment, the first air duct opening includes a first fan 211 disposed within the first cavity 110. The first fan 211 is used to drive air from the second cavity 120 into the first cavity 110. Specifically, to accelerate the airflow speed corresponding to the heating channel, a first fan 211 can be disposed corresponding to the first air duct opening (i.e., the position of the first fan 211 is understood as the position of the first air duct opening). By controlling the operation of the first fan 211, the air in the second cavity 120 is accelerated to flow into the first cavity 110. The first fan 211 can be a single fan or a fan group composed of multiple small fans.

[0042] In one embodiment, the third air duct opening includes a second fan 231 disposed within the second cavity 120. The second fan 231 drives the air within the second cavity 120 to flow into the third cavity 130. Specifically, to accelerate the airflow speed corresponding to the heating channel, a second fan 231 can be disposed corresponding to the third air duct opening (i.e., the position of the second fan 231 is the same as the position of the third air duct opening). By controlling the operation of the second fan 231, the air within the second cavity 120 is accelerated to flow into the third cavity 130. The second fan 231 can be a single fan or a fan group composed of multiple small fans.

[0043] In one embodiment, such as Figures 1 to 3 As shown, the charging pile of this utility model also includes a first temperature detection module 510 disposed outside the cabinet 100; the first temperature detection module 510 is used to obtain the external temperature of the cabinet 100 so as to open the heating air duct when the external temperature is lower than a first preset value. Specifically, the first temperature detection module 510 can be disposed outside the cabinet 100 to detect the external temperature of the cabinet 100. The system then determines whether the heating air duct needs to be opened based on the external temperature. In a specific embodiment, the heating air duct can be set to open when the external temperature is lower than -25℃ (corresponding to the first preset value). It can also be set to close the heating air duct when the external temperature is higher than a preset value. For example, the heating air duct can be closed when the detected external temperature is higher than -10℃. This specific setting process can be adjusted as needed and is not limited in this example. The first temperature detection module 510 may include one or more temperature sensors. Multiple temperature sensors can be disposed at different locations outside the cabinet to achieve accurate detection of the external temperature of the cabinet.

[0044] In one embodiment, the charging cabinet of this utility model further includes cooling ducts corresponding to the second cavity 120 and / or the third cavity 130; the cooling ducts are set to the open state when the charging pile is in cooling mode and to the closed state when the charging pile is in heating mode. Specifically, the charging cabinet is also provided with cooling ducts to cool the charging cabinet and prevent the charging pile from overheating during operation. Considering that the power module 410 in the second cavity 120 is the main source of heat for the charging cabinet's temperature rise, and the control module 420 in the third cavity 130 is sensitive to temperature changes, cooling ducts are set to correspond to one or both of the second cavity 120 and the third cavity 130 to achieve effective cooling of the charging pile. At the same time, to avoid conflicts between heating and cooling, the cooling ducts are closed and the heating ducts are open when the charging cabinet is in heating mode, at which time the charging pile is heated through the heating channel. When the charging station is set to cooling mode, the heating channel is closed and the cooling air duct is opened, and the charging station is cooled through the cooling channel.

[0045] In one specific embodiment, the cooling air ducts may include a first cooling air duct corresponding to the second cavity 120 and a second cooling air duct corresponding to the third cavity 130. That is, the first cooling air duct can be set to correspond to the second cavity 120, and the second cooling air duct can be set to correspond to the third cavity 130, so that the second cavity 120 and the third cavity 130 are cooled by the first cooling air duct and the second cooling air duct, respectively.

[0046] Optionally, the first cooling duct includes a first louver, a second louver, and a third fan 311 corresponding to the second cavity 120. The third fan 311 is used to draw outside air into the second cavity 120 through the first louver and out of the second cavity 120 through the second louver. Specifically, in the first cooling duct, the first and second louvers can be installed on the outside of the cabinet 100, and the third fan 311 can draw outside air into the second cavity 120 through the first louver and out of the second cavity 120 through the second louver, so that the flowing air can remove the heat inside the second cavity 120 and cool the second cavity 120. The third fan 311 can be a single fan or a fan group composed of multiple small fans.

[0047] Optionally, the second cooling duct includes a third louver, a fourth louver, and a fourth fan 312 corresponding to the third cavity 130. The fourth fan 312 is used to draw outside air into the third cavity 130 through the third louver and out of the third cavity 130 through the fourth louver. Specifically, in the second cooling duct, the third and fourth louvers can be installed on the outside of the cabinet 100, and the third fan 311 can draw outside air into the third cavity 130 through the third louver and out of the third cavity 130 through the fourth louver, so that the flowing air can remove the heat inside the third cavity 130 and cool the third cavity 130. The fourth fan 312 can be a single fan or a fan group composed of multiple small fans.

[0048] In one specific embodiment, the first and third louvers are a single unit, corresponding to a louver 320 disposed on one side of the cabinet 100. That is, the process of controlling the first and third louvers is the same process, which can be understood as the process of controlling louver 320. Similarly, the second and fourth louvers are a single unit, corresponding to a louver 330 disposed on the other side of the cabinet 100. That is, the process of controlling the second and fourth louvers is the same process, which can be understood as the process of controlling louver 330.

[0049] Optionally, when the cooling duct is closed, the first, second, third, and fourth louvers can be set to the closed state. When the cooling duct is set to close, the first, second, third, and fourth louvers can be closed simultaneously with the third fan 311 and the fourth fan 312.

[0050] In one embodiment, the charging pile of this utility model further includes a second temperature detection module 520 disposed inside the cabinet 100; the second temperature detection module 520 is used to acquire the internal temperature of the cabinet 100 so as to open the cooling duct when the internal temperature is higher than a second preset value. Specifically, a second temperature detection module 520 can be installed inside the cabinet 100 to detect the internal temperature of the cabinet 100. The system then determines whether the cooling duct needs to be opened based on the internal temperature. In a specific embodiment, the cooling duct can be set to open when the internal temperature is higher than 25°C (corresponding to the second preset value). It can also be set to close the cooling duct when the internal temperature is lower than a preset value. For example, the cooling duct can be closed when the external temperature is detected to be lower than 10°C. This specific setting process can be adjusted as needed and is not limited in this example. Multiple second temperature detection modules 520 can be installed, and these modules can be placed at different locations within the cabinet 100 to achieve accurate monitoring of the internal temperature of the cabinet 100. In one embodiment, the second temperature detection module 520 may include one or more temperature sensors for acquiring temperature data.

[0051] In one specific embodiment, the control motors for various fans and louvers can be located within the first cavity 110.

[0052] In the charging cabinet of this utility model, when the charging cabinet is in heating mode during operation, the heat generated by the power module 410 and other working modules inside the charging cabinet can be used as a heat source to heat the charging cabinet. No additional heat source circuit is required, and the circuit cost of the entire charging cabinet will not be increased.

It should be noted that for those skilled in the art, the above technical features can be freely combined, and several modifications and improvements can be made without departing from the concept of the present utility model, all of which fall within the protection scope of the present utility model.
