[0040] The following is a brief introduction to the relevant terminology used in this application.

[0041] IPX5: A waterproof rating that means the equipment can withstand low-pressure water jets from any direction without causing any harmful effects.

[0042] In recent years, the continuous expansion of the electric vehicle market and the accelerating pace of social production and life have placed higher demands on charging stations. Currently, charging stations primarily cool the charging components inside the station through airflow during the charging process. If the airflow is low, the charging components will overheat, limiting the charging rate and affecting their lifespan. Furthermore, many charging stations are now used outdoors, and the original waterproofing levels are no longer sufficient for some users, requiring higher protection levels to cope with harsh operating environments.

[0043] To address the aforementioned issues, this application provides a charging pile; please refer to... Figure 1 , Figure 2 , Figure 1 This is a three-dimensional schematic diagram of a charging pile provided in an embodiment of the present utility model. Figure 2 This is another three-dimensional schematic diagram of a charging pile provided by an embodiment of this utility model, as shown below. Figure 1 , Figure 2 As shown, the charging pile includes a pile body 101, an air inlet 102, and an air outlet 103; wherein the air inlet 102 and the air outlet 103 are respectively located on both sides of the pile body 101. Figure 1 The air inlet 102 shown is on the right and the air outlet 103 is on the left. This is only for illustration purposes. There are no restrictions on the specific locations of the air inlet 102 and the air outlet 103.

[0044] Please see Figure 3 , Figure 3 This is a top view of the internal structure of a charging pile provided in an embodiment of the present invention, as shown below. Figure 3 As shown, the air inlet chamber 104 and the air outlet chamber 118 are located inside the pile body 101, and the air inlet chamber 104 is connected to the air inlet door 102, while the air outlet chamber 118 is connected to the air outlet door 103; please refer to Figure 4 , Figure 5 , Figure 4 This is a schematic diagram of an air inlet door provided in an embodiment of the present invention. Figure 5 This is an exploded view of an air inlet door provided in an embodiment of the present invention, as shown in the diagram. Figure 4 , Figure 5 As shown, the air inlet door 102 includes an inner air inlet cover 202, an outer air inlet cover 204, and a first louver assembly 2031. The inner air inlet cover 202 forms an inner air inlet cavity 107, which is provided with at least two first air inlets 105 and second air inlets 106. The first louver assembly 2031 is disposed in the connection area between the first air inlets 105, the second air inlets 106, and the inner air inlet cavity 107, forming an air inlet channel; Figure 6 , Figure 7 As shown, Figure 6 This is a schematic diagram of an overall air outlet door provided in an embodiment of this utility model. Figure 7 This is an exploded view of an air outlet door provided in an embodiment of the present invention. The air outlet door 103 includes an inner air outlet cover 302, an outer air outlet cover 303, and a second louver assembly 2032. The inner air outlet cover 302 forms an inner air outlet cavity 115. The inner air outlet cavity 115 is provided with at least two air outlets: a first air outlet 116 and a second air outlet 117. The second louver assembly 2032 is disposed in the connection area between the air outlet and the inner air outlet cavity 115 to form an air outlet channel. The air inlet channel and the air outlet channel are multi-bend structures.

[0045] Specifically, the charging pile also includes a charging module 111. The function of the charging module 111 is to convert the AC power input from the grid into DC power that meets the charging requirements of electric vehicles and directly provide charging power to electric vehicles. The charging module 111 is placed between the air inlet cavity 104 and the air outlet cavity 118. The air inlet cavity 104 and the air outlet cavity 118 ensure airflow through multiple bends and sufficient ventilation mesh, ensuring that cold air continuously flows through the first air inlet 105, the second air inlet 106 and the air outlet 602 of the charging module 111, and promptly removes the heat generated during operation, avoiding charging rate limitation caused by overheating.

[0046] As can be seen, in this embodiment of the utility model, the charging pile includes a pile body 101, an air inlet 102, an air inlet cavity 104, an air outlet cavity 118, and an air outlet 103; the air inlet 102 and the air outlet 103 are respectively disposed on both sides of the pile body 101, the air inlet cavity 104 is connected to the air inlet 102, and the air outlet cavity 118 is connected to the air outlet 103; the air inlet 102 includes an inner air inlet cover 202, an outer air inlet cover 204, and a first louver assembly 2031, the inner air inlet cover 202 forms an inner air inlet cavity 107, and the inner air inlet cavity 107 is provided with at least two first air inlets 105 and second air inlets 106. 06. The first louver assembly 2031 is disposed in the connection area between the first air inlet 105, the second air inlet 106 and the air inlet cavity 107, forming an air inlet channel; the air outlet 103 includes an air outlet inner cover 302, an air outlet outer cover 303 and a second louver assembly 2032. The air outlet inner cover 302 forms an air outlet cavity 115, which is provided with at least two air outlets. The second louver assembly 2032 is disposed in the connection area between the first air outlet 116, the second air outlet 117 and the air outlet cavity 115, forming an air outlet channel; the air inlet channel and the air outlet channel have a multi-fold bending structure. Thus, by setting a multi-fold bending structure air duct at the charging pile air inlet 102 and air outlet 103, better waterproof protection is achieved while satisfying the ventilation and heat dissipation of the charging pile.

[0047] Specifically, please refer to Figure 4The air inlet door 102 is provided with dustproof cotton 201, which is located between the air inlet inner cavity 107 and the air inlet cavity 104, and the dustproof cotton 201 covers the first air inlet 105 and the second air inlet 106 of the air inlet cavity 104.

[0048] Dustproof cotton 201 is used to filter dust, particulate matter and other impurities in the airflow entering the charging pile, protecting core components, maintaining ventilation efficiency, and enhancing the environmental adaptability of the charging pile.

[0049] Specifically, please refer to Figure 6 , Figure 7 The air outlet 103 is equipped with a fan 301, which is located between the air outlet cavity 118 and the air outlet inner cavity 115. The air inlet side of the fan 301 is connected to the air outlet cavity 118, and the air outlet side of the fan 301 is connected to the air outlet inner cavity 115.

[0050] The fan 301 provides power for the airflow inside the charging pile, accelerating the airflow speed in the path of "first air inlet 105, second air inlet 106 → air inlet cavity 107 → air inlet cavity 104 → charging module 111 → air outlet cavity 118 → fan 301 → air outlet cavity 115 → first air outlet 116, second air outlet 117". Compared with natural ventilation, the active airflow of the fan 301 can increase the air volume under the same air duct structure. In addition, with the sound-absorbing cotton such as the fifth sound-absorbing cotton 112 and the sixth sound-absorbing cotton 113 in the air outlet cavity 118 and the air outlet cavity 115, the additional noise caused by airflow turbulence can be reduced, and the two can be optimized synergistically.

[0051] Specifically, the air inlet cavity 107 is sealed to the air inlet chamber 104 through the air inlet cover 202, and the side of the air inlet chamber 104 away from the air inlet cavity 107 is connected to the inside of the pile body 101; the side of the air outlet cavity 118 away from the air outlet cavity 115 is connected to the inside of the pile body 101, and the air outlet cavity 115 is sealed to the air outlet cavity 118 through the air outlet cover 302, so as to form a continuous ventilation path from the first air inlet 105 and the second air inlet 106 of the air inlet cavity 104 through the air inlet cavity 107, the air inlet cavity 104, the inside of the pile body 101, the air outlet cavity 118, the air outlet cavity 115 to the first air outlet 116 of the air outlet cavity 118.

[0052] Please refer to Figure 3 When the charging station is working, air enters from the first air inlet 105, the second air inlet 106, the first air inlet 105, the second air inlet 106, passes through the air inlet cavity 107, the dustproof cotton 201, the air inlet cavity 104, the charging module 111, the air outlet cavity 118, the fan 301, the air outlet cavity 115, and finally is discharged through the first air outlet 116 and the second air outlet 117.

[0053] Specifically, the edge of the first louver assembly 2031 is tightly fitted with the inner wall of the air inlet cover 202 and the air inlet cover 204, and the blades of the first louver assembly 2031 form an air inlet channel with a multi-fold bending structure; the edge of the second louver assembly 2032 is tightly fitted with the inner wall of the air outlet cover 302 and the air outlet cover 303, and the blades of the second louver assembly 2032 form an air outlet channel with a multi-fold bending structure.

[0054] Specifically, the first louver assembly 2031 is sandwiched between the inner air inlet cover 202 and the outer air inlet cover 204. Its outer periphery is tightly fitted to the inner wall of the inner air inlet cover 202 and the inner wall of the outer air inlet cover 204 by sealing strips, and is fixed to both by evenly distributed buckles along the edges to ensure no gaps at the joint. The three blades of this louver assembly (first blade 403, second blade 404, and third blade 405) are arranged in a stepped manner: the blades extend vertically upward along the inner wall of the outer air inlet cover 204 to form the first fold of the air inlet channel; the blades extend horizontally into the charging pile body and connect vertically with the blades to form the second fold; the blades bend vertically downward to connect to the air inlet end of the inner air inlet cover 202 to form the third fold. The gaps between the three blades form a continuous multi-fold curved air inlet channel. The inlet of this channel is aligned with the ventilation mesh of the outer air inlet cover 204, and the outlet communicates with the air inlet cavity 107 formed by the inner air inlet cover 202. It should be understood that the second louver assembly 2032 has the same structure as the first louver assembly 2031, and will not be described again here.

[0055] As can be seen, the tight fit between the edges of the first louver assembly 2031 and the second louver assembly 2032 and the inner and outer walls of the inner and outer covers prevents water from seeping in through the gaps between the components and the cover. At the same time, the multi-fold curved channel formed by the blades extends the water entry path, so that the sprayed water is blocked on the outside of the channel after multiple bends and cannot directly rush into the charging pile, meeting the IPX5 waterproof requirements and adapting to harsh environments such as outdoor rain and water spray. In addition, the multi-fold curved channel causes the noise generated by the charging module 111 and the fan 301 to be reflected multiple times in the channel, while the sound-absorbing cotton on the surface of the blades directly absorbs the reflected noise, reducing the generated noise decibels.

[0056] Specifically, both the first louver assembly 2031 and the second louver assembly 2032 include two fixing plates, three or more blades, and rivets. The two ends of the blades are respectively attached to the two fixing plates and are fixedly connected by rivets.

[0057] Please see Figure 8 , Figure 8 This is an exploded view of a louver assembly provided in an embodiment of this utility model, as shown below. Figure 8As shown, the louver assembly includes a first rivet 401, a first fixing plate 402, a first blade 403, a second blade 404, a third blade 405, a second fixing plate 406, and a second rivet 407. The first blade 403, the second blade 404, and the third blade 405 are attached to the first fixing plate 402 and the second fixing plate 406 at both ends, and are riveted and fixed by the first rivet 401 and the second rivet 407.

[0058] Specifically, the first louver assembly 2031 and the second louver assembly 2032 have completely identical structures; wherein, the two fixing plates, the first fixing plate 402 and the second fixing plate 406, extend vertically, and their lengths are adapted to the height of the right air inlet door / left air outlet door, and the inner sidewalls are provided with positioning grooves that match the blade ends; the three blades are arranged at intervals in the horizontal direction, and the two ends of each blade are respectively inserted into the positioning grooves of the two fixing plates, the first fixing plate 402 and the second fixing plate 406, and are tightly fitted with the inner sidewalls of the first fixing plate 402 and the second fixing plate 406; the first rivet 401 and the second rivet 407 are evenly distributed at intervals along the length direction of the first fixing plate 402 and the second fixing plate 406, and penetrate through the blade ends and the corresponding holes of the first fixing plate 402 and the second fixing plate 406, and the blades are fixed to the first fixing plate 402 and the second fixing plate 406 as one unit by the riveting process, forming a frame structure with a fixed angle.

[0059] Furthermore, the three blades are arranged at a preset angle: the first blade is at a 30° angle to the vertical direction, forming the first section of the airflow guide surface of the three-fold bend structure of the air inlet / outlet duct; the second blade is at a 15° angle to the horizontal direction, forming the second section of the airflow guide surface; and the third blade is at a 45° angle to the vertical direction, forming the third section of the airflow guide surface. The three blades work together to form an airflow guide channel that is perfectly adapted to the three-fold bend path of the duct.

[0060] As can be seen, in this embodiment, the rigid connection between the first fixing plate 402, the second fixing plate 406, the blade and the first rivet 401 and the second rivet 407 achieves precise adaptation with the three-fold curved air duct, which is the basic connection structure for the charging pile to achieve high protection and low noise effect.

[0061] Specifically, the air inlet cavity 104 is equipped with at least four cavity-shaped sound-absorbing cotton materials, each fixed to the inner wall of the air inlet cavity 104; the air outlet cavity 118 is equipped with at least four cavity-shaped sound-absorbing cotton materials, each fixed to the inner wall of the air outlet cavity 118. Please refer to [link / reference]. Figure 3The air inlet cavity 104 is equipped with a first sound-absorbing cotton 109, a second sound-absorbing cotton 110, a third sound-absorbing cotton 121, and a fourth sound-absorbing cotton 122; and the air outlet cavity 118 is equipped with a fifth sound-absorbing cotton 112, a sixth sound-absorbing cotton 113, a seventh sound-absorbing cotton 119, and an eighth sound-absorbing cotton 120. It also includes a filter cotton 108 for filtering suspended dust in the airflow without affecting the airflow speed.

[0062] Specifically, the first louver assembly 2031 includes louvered sound-absorbing cotton, which is disposed on the side of the louvers, and at least one louver has louvered sound-absorbing cotton on both sides; please refer to Figure 9 , Figure 9 This is a top view of the internal structure of a louver assembly provided in an embodiment of this utility model, as shown below. Figure 9 As shown, the first blade 403 includes the fifth blade 505 and the eleventh sound-absorbing cotton 504; the second blade 404 includes the sixth blade 507, the twelfth sound-absorbing cotton 506, and the thirteenth sound-absorbing cotton 508; and the third blade 405 includes the fourth blade 502, the ninth sound-absorbing cotton 501, and the tenth sound-absorbing cotton 503. It should be understood that the second louver assembly 2032 has the same structure as the first louver assembly 2031, and will not be described in detail here.

[0063] Specifically, please refer to Figure 3 The air inlet cavity 104 is also equipped with a first sound-absorbing cotton 109, a second sound-absorbing cotton 110, a third sound-absorbing cotton 121, and a fourth sound-absorbing cotton 122; the air outlet cavity 118 is also equipped with a fifth sound-absorbing cotton 112, a sixth sound-absorbing cotton 113, a seventh sound-absorbing cotton 119, and an eighth sound-absorbing cotton 120.

[0064] Specifically, please refer to Figure 10 , Figure 11 , Figure 12 . Figure 10 This is an exploded structural diagram of a louver assembly provided in an embodiment of this utility model. Figure 11 This is an exploded structural diagram of another louver component provided in an embodiment of this utility model. Figure 12 This is an exploded structural diagram of another louver component provided in this embodiment of the present invention; as shown... Figure 10 , Figure 11 , Figure 12 As shown, the fourth blade 502 has the tenth sound-absorbing cotton 503 and the ninth sound-absorbing cotton 501 installed on both sides; the sixth blade 507 has the twelfth sound-absorbing cotton 506 and the thirteenth sound-absorbing cotton 508 installed on both sides; and the fifth blade 505 has the eleventh sound-absorbing cotton 504 installed on one side.

[0065] The noise sources mainly come from the charging module 111 and the fan 301. The air inlet and outlet structure has a multi-bend design, and the side door has ventilation mesh holes from top to bottom, providing sufficient ventilation area. In addition, sound-absorbing cotton is installed in the air duct. Through structural design and sound-absorbing cotton, the product noise is reduced while ensuring that the charging efficiency is not affected.

[0066] Specifically, the air inlet and outlet ducts have a three-bend structure. Please refer to [link / reference]. Figure 9 It includes a three-fold curved structure channel formed by the fourth blade 502, the fifth blade 505, and the sixth blade 507.

[0067] Specifically, the ventilation mesh of the air inlet door 102 and the air outlet door 103 is continuously distributed along the height direction of the side door, forming a ventilation area that connects the inside and outside of the charging pile.

[0068] The air inlet door 102 has ventilation mesh holes on both its outer cover 204 and inner cover 202. The outer side of the outer cover 204 (facing the outside of the charging pile) has continuously distributed strip-shaped ventilation mesh holes along its height (from the top edge to the bottom edge), forming an external ventilation area spanning the entire height of the side door. Similarly, the inner side of the inner cover 202 (facing the inside of the charging pile) also has continuously distributed ventilation mesh holes of the same specifications along its height, forming an internal ventilation area. The external and internal ventilation areas are connected by a flow guide gap in the louver assembly. The external ventilation area, the flow guide gap in the first louver assembly 2031, and the internal ventilation area together constitute the ventilation area of ​​the air inlet door 102, enabling air communication between the external environment of the charging pile and the air inlet cavity 107. It should be understood that the air outlet door 103 has the same structure as the air inlet door 102, and will not be described further here.

[0069] When the charging pile is working, the external cold air first enters through the external ventilation area of ​​the air inlet cover 204, then through the guide gap of the first louver assembly 2031 (which is adapted to the first fold of the three-fold curved air inlet duct), and then through the internal ventilation area of ​​the air inlet cover 202 into the air inlet cavity 107, and finally merges into the air inlet duct; the hot air flows out from the air outlet cavity 115, then through the internal ventilation area of ​​the air outlet cover 302 into the guide gap of the louver assembly, and then through the external ventilation area of ​​the air outlet cover 303 to be discharged to the outside of the charging pile.

[0070] As can be seen, the ventilation mesh continuously distributed along the height of the side door forms a through-ventilation area. The ample ventilation area ensures that there is no significant resistance when the airflow passes through the charging module 111, which can promptly remove the heat generated by the charging module 111 during operation and extend the service life of the device. At the same time, it works in conjunction with the sound-absorbing cotton to achieve low noise. The continuous distribution of the ventilation mesh does not compress the installation space of the louver assembly, and the sound-absorbing cotton on the blades can fully contact the airflow passing through the mesh, directly absorbing airflow disturbances and noise generated by the charging module 111 and the fan 301.
