[0025] The following is an explanation of the relevant contents, concepts, meanings, technical issues, technical solutions, beneficial effects, etc. involved in the embodiments of the present application.

[0026] IPX5: IPX5 is a waterproof rating standard that indicates that the product can prevent water intrusion from large waves or water intrusion from rapid jets of water jets from the nozzles. That is, the water jet from the nozzle should have no negative effects when it hits the device casing from any angle.

[0027] In recent years, the scale of the electric vehicle market has continued to expand, the pace of social production and life has continued to accelerate, and the market has placed higher requirements on charging piles. At present, many charging piles are used in outdoor scenes. In order to achieve faster charging speeds, the charging devices in the cabinet are mainly cooled by air flow. If the heat dissipation efficiency is not good, it will lead to a low charging rate and affect the service life of the device. For outdoor charging piles, while dissipating heat, it is also necessary to take into account the use environment of rain and waterproofing to prevent rain from falling into the cabinet and causing circuit damage. At present, the existing charging piles that can meet the IPX5 waterproof requirements have a load on the air outlet duct structure and a large wind resistance, which leads to a slow air circulation speed, thereby affecting the heat dissipation efficiency; while charging piles with good heat dissipation performance cannot meet the outdoor waterproof protection requirements.

[0028] To solve the above problems, the embodiments of the present application provide a control method for a charging pile shutter, a shutter and related devices, so that by adjusting the opening and closing angles of the inner and outer shutters, the inner shutters can ensure the internal air circulation of the charging pile while the outer shutters can achieve reliable waterproof protection.

[0029] First, the method in the embodiment of the present application is applied to the controller of the charging pile, combined with Figure 1 A method for controlling the blinds of a charging pile in an embodiment of the present application is described. Figure 1It is a functional unit composition block diagram of a charging pile provided in an embodiment of the present application, wherein the charging pile 100 includes a controller 110, a shutter 120, a temperature sensor 130 and a rain sensor 140, and the charging pile 100 also includes an air inlet 150, the shutter 120 coincides with the air outlet position of the charging pile, and the shutter 120 is arranged at the air outlet. Among them, the controller 110 first detects that the charging pile 100 is in a working state, determines the temperature inside the charging pile through the temperature sensor 130, and determines the current rainfall through the rain sensor 140; secondly, determines the heat dissipation strategy according to the temperature inside the pile and the first temperature, and the first temperature refers to the lowest temperature required for the charging pile 100 to dissipate heat; then, determines the waterproof strategy according to the temperature inside the pile and the first temperature, as well as the current rainfall; finally, adjusts the first opening and closing angle of the inner shutter of the shutter 120 according to the heat dissipation strategy, and adjusts the second opening and closing angle of the outer shutter of the shutter 120 according to the waterproof strategy, the inner shutter is a shutter component installed inside the shutter 120, and the outer shutter is a shutter component installed outside the shutter 120.

[0030] Among them, the controller 110 is connected to the shutter 120. Specifically, the controller 110 is respectively connected to the sliding rod component in the shutter 120 and the fan. By controlling the sliding rod component, the second opening and closing angle of the outer shutter is controlled, and by controlling the operation of the fan, the first opening and closing angle of the inner shutter is controlled.

[0031] Among them, after the controller 110 opens the shutter 120, the air inlet 150 is connected to the air outlet, and the air circulation speed inside the charging pile 100 is adjusted by opening and closing the inner shutters in the shutters 120. The larger the opening angle of the inner shutters, the faster the air flow speed, and thus the better the heat dissipation effect; while ensuring heat dissipation, the controller 110 also determines the opening and closing of the outer shutters in the shutters 120 based on the rainfall. It should be understood that after the inner shutters are opened, the outer shutters will also open and will not remain closed. The controller 110 adjusts the opening and closing angles of the outer shutters based on the rainfall to ensure the waterproof effect; specifically, the greater the rainfall, the smaller the opening and closing angles of the outer shutters, until the minimum angle.

[0032] Specifically, the rain sensor 140 is installed at a higher position on the top or side of the charging pile 100, so that it can better contact the rain and avoid being blocked by the structure of the charging pile itself or surrounding objects; its working principle takes the optical rain sensor as an example, it emits light through a light-emitting diode. When raindrops pass through the light propagation path, the light will be refracted, scattered, etc., and the light intensity received by the receiver will change. According to the degree and frequency of the light intensity change, the amount of rainfall can be judged. The capacitive rain sensor detects rainfall by using raindrops falling on the sensor surface to change the capacitance value, which is not limited in this embodiment.

[0033] Combine the following Figure 2 A control method for a charging pile blind in an embodiment of the present application is described. Figure 2 : is a flow chart of a method for controlling a charging pile blind provided in an embodiment of the present application, which specifically includes the following steps: Step S210, detecting that the charging pile is in working state, determining the temperature inside the charging pile through a temperature sensor, and determining the current rainfall through a rainfall sensor.

[0034] Step S220, determining a heat dissipation strategy according to the temperature inside the pile and the first temperature.

[0035] Among them, the first temperature refers to the lowest temperature at which the charging pile needs to dissipate heat. Specifically, the normal working temperature range of a general charging pile is about -20℃-55℃, and the first temperature is 55℃; for example, when the temperature inside the charging pile is greater than 55℃, the electronic components and charging modules inside the charging pile will have an increased risk of failure due to overheating, which will cause the performance of power semiconductor devices (such as IGBT-insulated gate bipolar transistors) to decline, and their on-resistance will increase with the increase in temperature, thereby generating more heat, forming a vicious cycle. If the temperature is too high, key components such as capacitors may also be damaged.

[0036] In one possible example, a heat dissipation strategy is determined based on the temperature inside the pile and a first temperature, including: when the temperature inside the pile is less than or equal to the first temperature, the heat dissipation strategy is determined to be the first heat dissipation strategy, and the first heat dissipation strategy refers to a strategy for controlling the closing of inner shutters; when the temperature inside the pile is greater than the first temperature, the heat dissipation strategy is determined to be the second heat dissipation strategy, and the second heat dissipation strategy refers to adjusting the first opening and closing angle of the inner shutters to the maximum opening and closing angle.

[0037] Among them, when the temperature inside the pile is less than or equal to the first temperature, the charging efficiency of the charging pile will not be affected by the temperature, so it is invalid to actively implement the heat dissipation strategy, and keep the inner shutters closed; when the temperature inside the pile is greater than the first temperature, active heat dissipation is required to control the inner shutters to open to the maximum opening and closing angle; it should be understood that the maximum opening and closing angle is less than or equal to 90°.

[0038] Specifically, in a possible example, the Venetian blinds also include a fan, and the air outlet of the fan is arranged parallel to the inner blinds; adjusting the first opening and closing angle of the inner blinds of the Venetian blinds according to the heat dissipation strategy includes: determining the first opening and closing angle indicated by the heat dissipation strategy; according to the first opening and closing angle, controlling the wind force of the fan to blow the inner blinds to rotate and maintain the first opening and closing angle.

[0039] Among them, the air outlet of the fan is set directly opposite the inner louver. The fan blows air to the inner louver. Under the action of wind pressure, all the blades of the inner louver are opened at a certain angle, so that air enters from the air inlet of the charging pile, passes through the inner louver, and is discharged from the air outlet of the charging pile to achieve air circulation.

[0040] Specifically, the blades of the inner louver are low-wind resistance blades. The low-wind resistance design allows air to pass through the inner louver more smoothly. Under the same wind pressure, a larger ventilation volume can be achieved, thereby more effectively realizing the circulation and exchange of air inside and outside the charging pile.

[0041] The first opening and closing angle can be a fixed maximum opening and closing angle, or it can be determined according to the current temperature in the pile. When the temperature in the pile is greater than the first temperature, the higher the temperature, the larger the first opening and closing angle is to meet the heat dissipation requirement. Furthermore, the wind force of the fan is controlled to be greater to maintain the first opening and closing angle until the above-mentioned maximum opening and closing angle is reached.

[0042] It can be seen that in this example, by judging the temperature inside the pile and the first temperature, a heat dissipation strategy for the inner shutters is formulated. If the temperature inside the pile is greater than the first temperature, the opening and closing angles of the inner shutters are controlled to dissipate heat. If the temperature inside the pile is less than or equal to the first temperature, the inner shutters are kept closed. While saving overall energy consumption, the heat dissipation efficiency of the charging pile is guaranteed, the flexibility and adaptability of the shutter control are improved, the safety of the charging pile is ensured, and the service life is extended.

[0043] Step S230, determining a waterproofing strategy according to the temperature inside the pile, the first temperature, and the current rainfall.

[0044] In one possible example, a waterproof strategy is determined based on the temperature inside the pile, the first temperature, and the current rainfall, including: when the temperature inside the pile is less than or equal to the first temperature, the waterproof strategy is determined to be the first waterproof strategy, and the first waterproof strategy refers to a strategy for controlling the closing of external shutters; when the temperature inside the pile is greater than the first temperature, the waterproof strategy is determined based on the current rainfall, and the current rainfall is inversely proportional to the second opening and closing angle.

[0045] Among them, when the temperature inside the pile is less than or equal to the first temperature, according to the above content, the inner shutters are kept in a closed state, so the shutters as a whole do not need to dissipate heat, and the outer shutters only need to consider waterproof protection. Therefore, the waterproof strategy is determined as the first strategy, and the outer shutters are kept closed. Without considering the heat dissipation of the charging pile, the outer shutters are completely closed to ensure the highest level of waterproof protection. Specifically, the waterproof level of IPX5 can be achieved.

[0046] Among them, when the temperature inside the pile is higher than the first temperature, if it is completely closed, the air cannot be discharged from the outlet of the charging pile, air circulation cannot be achieved, and the heat dissipation effect is not achieved. Therefore, at this time, the waterproof strategy needs to comprehensively consider the heat dissipation needs and determine the second opening and closing angle according to the current rainfall. The greater the current rainfall, the smaller the second opening and closing angle, but the minimum second opening and closing angle must not be less than 0°, otherwise the outer shutter will be closed.

[0047] It can be seen that in this example, the waterproof strategy is determined by judging the relationship between the temperature inside the pile and the first temperature. When the temperature inside the pile is less than or equal to the first temperature, the outer shutters are kept closed to achieve a waterproof effect. When the temperature inside the pile is greater than the first temperature, the heat dissipation demand and the current rainfall are comprehensively considered to control the outer shutters to open to the second angle. While ensuring basic heat dissipation, it prevents rainwater from entering the charging pile from the outside. By controlling the opening and closing of the outer shutters, both heat dissipation and waterproofing functions are achieved, thereby improving the adaptability and protection of the shutters to outdoor working conditions, and ensuring the safety and work efficiency of the charging pile.

[0048] In one possible example, a waterproof strategy is determined based on the current rainfall, including: determining the relationship between the current rainfall and a first rainfall, the first rainfall being the minimum rainfall that indicates that the charging pile needs to be waterproof; when the current rainfall is less than or equal to the first rainfall, determining the waterproof strategy to be the second waterproof strategy, the second waterproof strategy refers to a strategy of controlling the second opening and closing angle of the external blinds to the maximum opening and closing angle; when the current rainfall is greater than the first rainfall and less than the second rainfall, determining the waterproof strategy to be the third waterproof strategy, the third waterproof strategy refers to a strategy of adjusting the second opening and closing angle according to the current rainfall, the greater the current rainfall, the smaller the second opening and closing angle, and the first rainfall is less than the second rainfall; when the current rainfall is greater than the second rainfall, determining the waterproof strategy to be the fourth waterproof strategy, the fourth waterproof strategy refers to a strategy of controlling the second opening and closing angle to the minimum opening and closing angle.

[0049] Specifically, when the current rainfall is less than or equal to the first rainfall, the first rainfall can be, for example, 25 mm / d, indicating that the rainfall in the environment where the charging pile is located does not require targeted waterproofing operations. Therefore, the outer louvers fully serve the heat dissipation function and control the maximum opening angle of the outer louvers. It should be understood that the maximum opening angle of the outer louvers is smaller than the maximum opening angle of the inner louvers, that is, the maximum opening angle of the outer louvers is less than 90°.

[0050] Among them, the second rainfall is the rainfall associated with the opening angle of the outer louver to the minimum angle, and the second rainfall is greater than the first rainfall. Specifically, the second rainfall can be 50 mm / d. When the current rainfall is greater than the first rainfall and less than the second rainfall, the second opening and closing angle of the outer louver is adjusted according to the size of the rainfall. The greater the rainfall, the smaller the second opening and closing angle is, so as to play a waterproof role. Exemplarily, when the current rainfall increases from the first rainfall to the second rainfall, the second opening and closing angle gradually decreases with the increase of rainfall, from 100% of the maximum opening and closing angle to 25% of the maximum opening and closing angle. Taking the maximum opening and closing angle of 80° as an example, the second opening and closing angle decreases from 80° to 20°.

[0051] Among them, when the current rainfall is greater than the second rainfall, it means that the rainfall is very large at this time. In order to ensure the waterproof effect, the second opening and closing angle of the outer shutter needs to be reduced. However, continuing to reduce the second opening and closing angle may affect the heat dissipation effect of the charging pile. Therefore, it is chosen to keep the second opening and closing angle to the minimum opening and closing angle, taking into account both the waterproof effect and the heat dissipation effect. The minimum opening and closing angle can be the above-mentioned 25% of the maximum opening and closing angle, or it can be 10%, or 15%, without restriction.

[0052] It can be seen that in this example, by determining the relationship between the current rainfall and the first rainfall, the waterproof strategy is determined to control the external blinds to ensure the waterproof effect while taking into account the heat dissipation effect. The second opening and closing angle of the external blinds is determined according to the current rainfall, thereby improving the environmental adaptability of the blinds control, avoiding only focusing on the waterproof effect and affecting the heat dissipation, and meeting the outdoor waterproof protection performance of the charging pile.

[0053] Step S240, adjusting a first opening and closing angle of the inner louvers of the louvers according to the heat dissipation strategy, and adjusting a second opening and closing angle of the outer louvers of the louvers according to the waterproof strategy.

[0054] The inner louver is a louver assembly installed inside the louver, and the outer louver is a louver assembly installed outside the louver. Specifically, the opening direction of the inner louver is consistent with the opening direction of the outer louver. Based on the above content, the blades of the inner louver will rotate under the wind pressure generated by the fan to maintain the first opening and closing angle; one side of the outer louver faces the inside of the louver, and the other side faces the outside.

[0055] It can be seen that in this embodiment, first, it is detected that the charging pile is in working state, the temperature inside the charging pile is determined by the temperature sensor, and the current rainfall is determined by the rainfall sensor; secondly, the heat dissipation strategy is determined according to the temperature inside the pile and the first temperature, and the first temperature refers to the lowest temperature that the charging pile needs to dissipate heat; then, the waterproof strategy is determined according to the temperature inside the pile and the first temperature, as well as the current rainfall; finally, the first opening and closing angle of the inner shutter of the shutter is adjusted according to the heat dissipation strategy, and the second opening and closing angle of the outer shutter of the shutter is adjusted according to the waterproof strategy. The inner shutter is a shutter component installed inside the shutter, and the outer shutter is a shutter component installed outside the shutter. In this way, heat dissipation is ensured by the inner shutter and waterproofing is ensured by the outer shutter, which meets the rigorous application conditions of outdoor charging piles and improves the working efficiency and safety of the charging piles.

[0056] In one possible example, the Venetian blinds also include a connecting rod, the outer blinds are arranged on the connecting rod, and the connecting rod is connected to a controller; adjusting the second opening and closing angle of the outer blinds of the Venetian blinds according to the waterproof strategy includes: determining the second opening and closing angle indicated by the waterproof strategy; according to the second opening and closing angle, controlling the connecting rod to slide up and down to control the rotation of the outer blinds to the second opening and closing angle.

[0057] Specifically, the outer shutter has multiple blades, each blade is connected to a connecting rod, and multiple connecting rods are fixed on the sliding rod. The controller controls the sliding rod's motor to control the sliding of the sliding rod up and down, thereby controlling the connecting rod to slide up and down, and finally controlling the blades of the outer shutter to rotate and open and close.

[0058] In one possible example, the charging pile also includes a heater; the method also includes: determining the relationship between the temperature inside the pile and a second temperature, the second temperature being the maximum temperature that the charging pile needs to be kept warm; when the temperature inside the pile is less than or equal to the second temperature, controlling the heater to start to increase the internal ambient temperature of the charging pile; and controlling the inner and outer shutters to close.

[0059] Among them, when the charging pile is in a low temperature environment, the performance of the electronic components inside the charging pile, such as capacitors, resistors, integrated circuits, etc., will be affected by the low temperature. For example, the capacity of the capacitor will decrease as the temperature decreases, which may affect the filtering effect of the charging pile and cause the quality of the output DC power to decrease. At the same time, low temperature may cause the pins, solder joints and other parts of the electronic components to shrink, produce microcracks, increase contact resistance, and affect signal transmission and current flow. Specifically, the second temperature is lower than the first temperature, and the second temperature can be, for example, -40°C. When the temperature inside the pile is less than or equal to the second temperature, in order to maintain the charging efficiency of the charging pile, it is necessary to heat the pile and keep the inner and outer shutters of the shutters closed to ensure that the space is closed and improve the heating effect.

[0060] It can be seen that in this example, considering that when the temperature inside the pile is too low, it will also lead to problems such as poor charging efficiency. By controlling the heater to increase the ambient temperature inside the charging pile, and at the same time controlling the blinds to ensure that the internal space of the charging pile is closed, the heating effect is optimized, which is beneficial to ensure the charging efficiency of the charging pile.

[0061] The present application also provides a blind. For details, see Figure 3 and Figure 4 , Figure 3 is a schematic diagram of a three-dimensional structure of a shutter provided in an embodiment of the present application, Figure 4 1 is a schematic diagram of the three-dimensional structure of another shutter provided in an embodiment of the present application. The shutter is arranged at the air outlet position of the charging pile. The charging pile includes a controller connected to the shutter. The controller is used to execute any one of the methods as described above. The shutter 120 includes: a window 402, the window 402 includes: a shutter fixing frame 501, a lower fixing frame 502, an upper fixing frame 503 and a fan fixing frame 504. The upper fixing frame 503 is installed on the top of the window 402, and the lower fixing frame 502 is installed on the bottom of the window 402. The shutter fixing frame 501 is installed on both sides of the window 402. Pins are provided on the shutter fixing frame 501. Multiple shutter components are fixed to the shutter fixing frame 501 by pins, so that the multiple shutter components can open and close with the pins as the center. The shutter components include: an inner shutter component 40 4 and an outer louver assembly; a fan 403, the fan 403 is installed on the fan fixing frame of the window 402, the plane where the air outlet of the fan 403 is located is parallel to the fan fixing frame 504, and the fan fixing frame 504 is located at the rear end of the window 402; an inner louver assembly 404, the inner louver assembly 404 is installed inside the window 402, and the inner side of the inner louver assembly 404 faces the air outlet of the fan 403; an outer louver assembly, the outer louver assembly is installed inside the window 402, and is parallel to the inner louver assembly 404, and the opening and closing direction of the outer louver assembly is consistent with the opening and closing direction of the inner louver assembly 404; a protective mesh plate 401, the protective mesh plate 401 is installed at the front end of the window 402, and a plurality of vents are provided on the protective mesh plate 401, and the plurality of vents connect the internal space of the shutter 120 with the outside.

[0062] Specifically, in one possible example, see Figure 5 and Figure 6 , Figure 5 is a schematic diagram of the internal structure of a shutter provided in an embodiment of the present application, Figure 6 This is a schematic diagram of the internal structure of another type of shutter provided in an embodiment of the present application. The outer shutter assembly 406 also includes: outer shutter blades 508, connecting rods 509, and sliding rods 510; multiple outer shutter blades 508 are connected to multiple connecting rods 509 through pins 507; and multiple connecting rods 509 are fixed to the sliding rod 510 through pins 507.

[0063] Specifically, the window 402 also includes a fan partition 505, which is used to place and separate multiple fans 403; the rear end of the fan 403 also includes a fan screw 405 for fixing the fan 403; the inner louver assembly 404 also includes inner louver blades 506.

[0064] Specifically, the sub-components of the outer louver assembly 406 are fixed to each other by pins, and the up and down sliding movement of the slide rod 510 is converted into the opening and closing of the outer louver blades 508 through the connecting rod 509, and the slide rod 510 can be matched with a small servo or a small motor mechanism according to actual conditions to achieve up and down sliding.

[0065] Optionally, when applied to charging piles with different size requirements, the size of the shutter 120 can be appropriately adjusted, and the specifications and quantity of the fan 403, the inner shutter assembly 404, and the window 402 can be adjusted accordingly.

[0066] Specifically, in a possible example, when the lower fixing frame 502 is installed at the bottom of the window 402 , there is an angle between the lower fixing frame 502 and the plane where the bottom of the window 402 is located.

[0067] The lower fixing frame 502 may have a certain bending angle, or may have an angle with the bottom of the window body 402 , so as to facilitate drainage of accumulated water and prevent the accumulated water that falls into the shutter from accumulating in the lower fixing frame 502 .

[0068] Based on the above-mentioned control method of the charging pile blinds, the blinds provided in the embodiment of the present application can be realized: when the charging pile is in the standby state, the fan 403 stops working, and the inner blinds 506 naturally droop under the action of gravity (such as Figure 5 As shown), since the louvers are provided with bending edges, the bending edges will block the gaps between the adjacent inner louver blades 506. At this time, the outer louver blades 508 are also in a closed state under the control of the motor, and the inner and outer louver components form two waterproof walls, which can specifically achieve the IPX5 protection level.

[0069] When the charging pile is working, the fan 403 is turned on and blows air to the inner louver blades 506. Under the action of wind pressure, all the inner louver blades 506 are opened (such as Figure 6 As shown), the charging pile exhausts air and dissipates heat to the outside through the shutter 120. If water rushes toward the shutter 120, the water will be blocked by the protective mesh 401, the inner shutter assembly 404, the outer shutter assembly 406 and the window 402, and the IPX4 protection level can be achieved.

[0070] As in the control method described above, after the charging pile starts charging, when the temperature inside the pile T≤-40°C (the second temperature): the temperature sensor and the rainfall sensor send signals to the controller to control the heater to turn on and the fan 403 to remain off, and the heater heats the ambient temperature inside the charging pile; the controller controls the motor to close the outer louver 508, at which time both the inner and outer louvers are in a closed state, forming a closed space to reduce heat loss.

[0071] When the temperature inside the pile is -40℃<T≤55℃ (T is greater than the second temperature and less than or equal to the first temperature): the temperature sensor and the rainfall sensor send signals to the controller, execute the first heat dissipation strategy, control the heater and the fan 403 to remain in the closed state, at this time, the inner and outer shutters are in the closed state, and the charging pile generates heat through the continuous operation of the charging module and various electrical components.

[0072] When the temperature inside the pile T>55℃ (greater than the first temperature), the temperature sensor and rainfall sensor send signals to the controller, and the waterproof strategy is determined according to the current rainfall: If the current rainfall X≤25mm (less than or equal to the first rainfall), the second waterproof strategy is executed, the heater is controlled to remain closed, the fan 403 is turned on, the inner louver 506 is opened under the action of the wind pressure of the fan 403, and the outer louver 508 is driven to reach the maximum opening angle, and the air enters the cabinet from the air inlet, passes through the charging module and various electrical components in the cabinet in turn to achieve cooling, and finally is discharged from between the multiple inner louver blades 506; if the current rainfall, 25mm≤X<50mm (greater than the first rainfall and less than the second rainfall), the inner louver 506 is controlled to open, and the outer louver 508 is controlled to gradually decrease to 25% of the maximum opening angle according to the rainfall to reduce the water inlet area; if the current rainfall X≥50mm (greater than the second rainfall), the inner louver 506 is controlled to remain unchanged at an opening angle, and the outer louver 508 is kept at 25% of the maximum opening angle. At this time, the rainfall is large and waterproofing needs to be performed first. Optionally, the above temperature threshold can be appropriately adjusted according to actual applications.

[0073] The embodiment of the present application can divide the electronic device into functional units according to the above method example. For example, each functional unit can be divided according to each function, or two or more functions can be integrated into one processing unit.
