Description

Technical Field

[0001] This application relates to the field of charging pile technology, and in particular to a ventilation component and a charging pile. Background Technology

[0002] Ventilation components, as structures connecting the interior and exterior of equipment to facilitate airflow exchange, typically feature ventilation channels that directly communicate with the equipment's interior to meet its ventilation needs. However, in related technologies, ventilation components suffer from insufficient waterproofing: when exposed to external water sources, water can penetrate the equipment's interior through the ventilation channel inlet. The low waterproofing rating of this ventilation structure makes it difficult to effectively prevent water from damaging the equipment's interior. Utility Model Content

[0003] This application provides a ventilation component and a charging pile, which improves the waterproof rating of the ventilation structure, thereby at least partially solving the above-mentioned technical problems.

[0004] To achieve the above objectives, according to a first aspect of this application, a ventilation assembly is provided, the ventilation assembly comprising: A protective cover is used to install on a door panel. The protective cover covers the outer periphery of the ventilation structure of the door panel and forms a protective cavity with the door panel. The protective cover is provided with a first ventilation opening that communicates with the protective cavity. The first filter assembly is connected to the protective cover and covers the first vent. The first vent's projected area on the door panel is located outside the area where the ventilation structure is situated.

[0005] In some embodiments of this application, the door panel has a top edge and a bottom edge that are opposite each other in the height direction, and a first vent is disposed near the top edge relative to the ventilation structure.

[0006] In some embodiments of this application, the first vent and the ventilation structure are offset by a distance H in the height direction, wherein 60mm≤H≤80mm.

[0007] In some embodiments of this application, the first filtering component includes: The first filter element is installed inside the protective cavity and covers the first ventilation opening; A fixed bracket connects the first filter element and the protective cover.

[0008] In some embodiments of this application, there are two fixing brackets, which are respectively disposed on opposite sides of the first vent; at least a portion of the fixing bracket is spaced apart from the inner wall of the protective cover to form a receiving groove; the first filter element is installed in the receiving groove.

[0009] In some embodiments of this application, the door panel has a top edge and a bottom edge that are opposite each other in the height direction, and the bottom end of the first filter facing the bottom edge is closer to the bottom edge relative to the lower boundary of the first vent.

[0010] In some embodiments of this application, the protective cover is further provided with a second vent communicating with the protective cavity. The second vent and the first vent are located on different walls of the protective cover, and the ventilation assembly further includes: The second filter assembly includes a second filter element and a connecting structure. The second filter element is disposed at the top of the fixed bracket and covers the second vent. The connecting structure is connected to the protective cover to fix the second filter element.

[0011] In some embodiments of this application, the door panel has a top edge and a bottom edge that are opposite each other in the height direction; the protective cover has an end plate and a surrounding plate that are opposite each other in the thickness direction, and the surrounding plate is connected between the end plate and the door panel to jointly form a protective cavity; a second vent is provided on the wall surface of the surrounding plate near the top edge; The height direction is perpendicular to the thickness direction.

[0012] In some embodiments of this application, the enclosure includes two side panels disposed opposite each other along the width direction; the connecting structure includes two connecting plates spaced apart along the width direction, and a pressure plate connected between the two connecting plates; When the connecting plate is connected to the corresponding side plate, the pressure plate overlaps the side of the second filter element facing away from the protective cavity; The thickness direction, height direction, and width direction are all perpendicular to each other.

[0013] In some embodiments of this application, one of the connecting plate and the side plate is provided with a snap-fit ​​groove, and the other is provided with a snap-fit ​​protrusion, the snap-fit ​​protrusion being snap-fitted into the snap-fit ​​groove.

[0014] According to a second aspect of this application, a charging station is provided, the charging station comprising: Cabinet; The door panel, connected to the cabinet body and located on the air intake side of the cabinet body, has a ventilation structure connecting the exterior and interior of the cabinet body; and, The ventilation component described in any of the above technical solutions is installed on the wall surface of the door panel facing the interior of the cabinet.

[0015] In some embodiments of this application, the door panel has a vertical height direction and a thickness direction, and a plurality of ventilation components are arranged at intervals along the height direction on the wall surface of the door panel facing the interior of the cabinet. The dimensions of two adjacent protective covers are not equal in the thickness direction.

[0016] In some embodiments of this application, the door panel has a top edge and a bottom edge that are opposite each other in the height direction, and the protective cover has an end plate that is opposite to the door panel in the thickness direction; In two adjacent protective covers, the distance between the end plate of the protective cover closer to the bottom edge and the door panel is D1, and the distance between the end plate of the protective cover farther from the bottom edge and the door panel is D2, where 7mm≤D1-D2≤20 mm.

[0017] In some embodiments of this application, the door panel has a top edge and a bottom edge that are opposite each other in the height direction, and a water-retaining eave is provided on the wall surface of the door panel facing the interior of the cabinet. The water-retaining eave is located on the side of the ventilation structure near the top edge.

[0018] In the ventilation assembly of this application embodiment, the above-described technical solution completely offsets the projected area of ​​the first vent on the door panel from the area where the ventilation structure is located. Therefore, when rainwater or waterproofing test spray water from the side of the door panel facing away from the protective cover enters the protective cavity through the ventilation structure, since the projected area of ​​the first vent does not overlap with the ventilation structure area, the water flow will not directly hit the first vent. This effectively prevents rainwater from entering the equipment (such as a charging pile) through the first vent, reducing the risk of rainwater intrusion. In other words, the ventilation structure ensures that the equipment can effectively prevent water from entering its interior even when subjected to high-intensity, multi-directional water jet impacts, thus improving the waterproof rating of the ventilation assembly and ensuring its reliable operation in harsh environments (such as heavy rain and humid conditions).

Detailed Implementation

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] In the description of this application, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0025] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0026] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; or they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0027] This application provides a ventilation component and a charging pile, which will be described in detail below. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments of this application. Furthermore, the descriptions of each embodiment have their own emphasis; parts not described in detail in a certain embodiment can be referred to in the relevant descriptions of other embodiments.

[0028] Ventilation components, as structures connecting the interior and exterior of equipment to facilitate airflow exchange, typically feature ventilation channels that directly communicate with the equipment's interior to meet its ventilation needs. However, in related technologies, ventilation components suffer from insufficient waterproofing: when exposed to external water sources, water can penetrate the equipment's interior through the ventilation channel inlet. The low waterproofing rating of this ventilation structure makes it difficult to effectively prevent water from damaging the equipment's interior.

[0029] Therefore, please refer to Figure 1 , Figure 2 and Figure 3 This application provides a ventilation assembly 10, which includes a protective cover 1 and a first filter assembly 2. The protective cover 1 is installed on a door panel 20, covering the outer periphery of the ventilation structure 201 of the door panel 20 and forming a protective cavity 11 with the door panel 20. The protective cover 1 is provided with a first vent 12 communicating with the protective cavity 11. The first filter assembly 2 is connected to the protective cover 1 and covers the first vent 12. The orthographic projection area of ​​the first vent 12 on the door panel 20 is located outside the area where the ventilation structure 201 is located.

[0030] By adopting the above design, the projected area of ​​the first vent 12 on the door panel 20 is completely offset from the area where the ventilation structure 201 is located. Therefore, when rainwater or water sprayed during waterproof testing from the side of the door panel 20 facing away from the protective cover 1 enters the protective cavity 11 through the ventilation structure 201, the water flow will not directly hit the first vent 12 because the projected area of ​​the first vent 12 does not overlap with the area of ​​the ventilation structure 201. This effectively prevents rainwater from entering the equipment (such as a charging pile) through the first vent 12, reducing the risk of rainwater intrusion. In other words, the ventilation structure 201 can effectively prevent water from entering the equipment even when subjected to high-intensity, multi-directional water spray impacts, helping to improve the waterproof rating of the ventilation component 10 and ensuring its reliable operation in harsh environments (such as heavy rain and humid conditions).

[0031] For example, the IPX5 waterproof rating test method uses a nozzle with an inner diameter of 6.3 mm to spray water at a flow rate of 12.5 L / min from a distance of 2.5 m to 3 m onto the surface of the test sample (such as ventilation component 10) in any direction for at least 3 minutes. After the IPX5 waterproof rating test, the ventilation component 10 described in this application showed no significant attenuation or failure in its ventilation, airflow guidance, and filtration functions. Its overall functional state remained essentially the same as before the test, and it meets the IPX5 waterproof rating protection requirements.

[0032] To provide a clearer description of the ventilation assembly 10 below, it is assumed that the door panel 20 has two perpendicular width directions X, thickness directions Y, and height directions Z.

[0033] The door panel 20 has a top edge 202 and a bottom edge 203 positioned opposite each other in the height direction Z. The first vent 12 is located near the top edge 202 relative to the ventilation structure 201. In outdoor environments or environments where rain is possible, rainwater entering the protective cavity 11 through the ventilation structure 201 will naturally settle downwards due to gravity. Since the first vent 12 is positioned relatively high, the risk of rainwater directly entering the equipment through it is further reduced. Even if a small amount of rainwater enters the protective cavity 11, it will flow downwards due to gravity, making it difficult for it to penetrate the equipment through the high-positioned first vent 12, thus effectively improving the equipment's waterproof protection capability under harsh weather conditions.

[0034] Specifically, such as Figure 2 and Figure 3 As shown, the first vent 12 and the ventilation structure 201 are offset by a distance H in the height direction Z, where 60mm≤H≤80mm. This offset distance ensures that rainwater entering the protective cavity 11 from the ventilation structure 201 settles sufficiently downwards under gravity, while preventing rainwater from being carried by airflow and directly crossing the height difference to intrude into the first vent 12 due to insufficient distance, thus effectively protecting the interior of the equipment from rainwater erosion.

[0035] If the offset distance is too small (<60mm), the contact area between the airflow and rainwater will increase significantly, making raindrops more susceptible to being drawn in and carried to higher positions by the airflow, increasing the risk of rainwater intrusion into the first vent 12. Conversely, if the distance is too large (>80mm), it will cause the airflow path to become excessively circuitous, which will not only increase the flow resistance of the ventilation system but may also reduce the overall ventilation efficiency and affect the heat dissipation performance of the equipment. Within the range of 60mm≤H≤80mm, it is possible to maintain the smoothness of airflow organization while ensuring waterproof reliability, achieving a simultaneous improvement in protection and functionality.

[0036] As an example, the value of H can be 60.0 mm, 62.5 mm, 65.0 mm, 67.5 mm, 70.0 mm, 72.5 mm, 75.0 mm, 77.5 mm, or 80.0 mm. It should be noted that the scope of protection of this application is not limited to the listed values, but covers all technical solutions within the range of "60.0 mm to 80.0 mm". Those skilled in the art will understand that selecting any other numerical point within the range, such as 63 mm, 67 mm, 72 mm, 74 mm, 78 mm, etc., can achieve the purpose of this application.

[0037] Please combine Figures 2 to 4 The first filter assembly 2 includes a first filter element 21 and a fixing bracket 22. The first filter element 21 is disposed inside the protective cavity 11 and covers the first vent 12. The fixing bracket 22 connects the first filter element 21 and the protective cover 1. The first filter element 21 can directly cover the first vent 12, which can filter the airflow entering the equipment through the first vent 12, preventing impurities from entering the equipment with the airflow and ensuring the cleanliness of the airflow entering the equipment. In addition, the fixing bracket 22 connects the first filter element 21 and the protective cover 1, providing mechanical support and fixing function for the first filter element 21, ensuring that the first filter element 21 can always cover the first vent 12 when subjected to airflow impact, vibration or external collision, and preventing the first filter assembly 2 from failing due to displacement.

[0038] Please refer to Figures 4 to 6 In this technical solution, there are two fixing brackets 22, which are respectively arranged on opposite sides of the first ventilation opening 12. At least a portion of the fixing bracket 22 forms a receiving groove 221 with the inner wall of the protective cover 1. The first filter element 21 is slidably engaged with the groove wall of the receiving groove 221 and disposed within the receiving groove 221. The first filter element 21 can be directly slid into the receiving groove 221 through the groove opening 222. The user or maintenance personnel only need to push the filter element from the groove opening 222 into the receiving groove 221 to complete the installation. When disassembling, it can be removed by sliding in the opposite direction, so as to achieve quick installation and removal of the first filter element 21 and simplify the maintenance (e.g., replacement or cleaning) efficiency of the first filter element 21. In this embodiment, one end of the fixing bracket 22 is fixedly connected to the inner wall of the protective cover 1, and the remaining part is spaced apart from the inner wall of the protective cover 1, forming the receiving groove 221 through the space.

[0039] Of course, in other embodiments not shown in the accompanying drawings, the two fixed supports 22 are respectively disposed on opposite sides of the first vent 12. Each fixed support 22 is provided with a receiving groove (not shown in the accompanying drawings). The first filter element 21 is slidably fitted with the groove wall of the receiving groove and is installed in the receiving groove through the groove opening. In this embodiment, the receiving groove is directly formed on the fixed support 22, and its two limiting walls along the through direction of the first vent 12 are both formed by the structure of the fixed support 22 itself.

[0040] It is understood that the protective cover 1 has an end plate 14 and a surrounding plate 15. The end plate 14 and the door plate 20 are arranged opposite each other along the thickness direction Y. The surrounding plate 15 connects the end plate 14 and the door plate 20 to jointly form a protective cavity 11. The surrounding plate 15 includes two side plates 152 arranged opposite each other along the width direction X. When the first ventilation opening 12 is set on the end plate, two fixing brackets 22 are respectively set on opposite sides of the first ventilation opening 12 along the width direction X. When the first ventilation opening is set on the side plate 152, two fixing brackets 22 are respectively set on opposite sides of the first ventilation opening 12 along the thickness direction Y.

[0041] Please refer to Figure 7 and Figure 8 The door panel 20 has a top edge 202 and a bottom edge 203 that are opposite each other in the height direction Z. The end of the first filter element 21 facing the bottom edge 203 is closer to the bottom edge 203 relative to the lower boundary of the first vent 12. When water splashes from the ventilation structure 201 into the protective cavity 11, because the end of the first filter element 21 facing the bottom edge 203 is closer to the bottom edge 203 relative to the lower boundary of the first vent 12, its extended portion can effectively intercept and absorb the splashed water droplets, thereby blocking the path of water droplets into the equipment through the first vent 12, providing reliable waterproof protection for the equipment.

[0042] For example, the protective cover 1 has an end plate 14 disposed opposite to the door panel 20, and a first vent 12 is disposed on the end plate 14. Under severe weather conditions such as heavy rain, even if external rainwater enters the protective cavity 11 through the ventilation structure 201, this rainwater will first splash onto the surface of the opposite end plate 14. Since the bottom end 211 of the first filter element 21 (i.e., the end near the bottom edge 203 of the door panel 20) is closer to the bottom edge 203 than the lower boundary 121 of the first vent 12 (i.e., the wall surface near the bottom edge 203 of the door panel 20), the water droplets splashed onto the end plate 14 will be effectively adsorbed or retained by the porous structure of the portion of the first filter element 21 that extends downward beyond the first vent 12, thereby blocking the path of water droplets to continue entering the equipment through the first vent 12 and reducing the risk of rainwater intrusion into the equipment.

[0043] Please continue to refer to Figures 2 to 5In this embodiment, the protective cover 1 is further provided with a second vent 13 communicating with the protective cavity 11. The second vent 13 and the first vent 12 are located on different wall surfaces of the protective cover 1. The ventilation assembly 10 also includes a second filter assembly 3, which is connected to the protective cover 1 and covers the second vent 13. The first vent 12 and the second vent 13 are located on different wall surfaces of the protective cover 1, which can guide airflow from different directions of the protective cover 1 into the equipment, forming a multi-directional airflow path, effectively increasing the ventilation surface area of ​​the protective cover 1, and improving the overall ventilation efficiency of the ventilation assembly 10. Furthermore, it can also ensure that after the external air enters the protective cavity 11 through the ventilation assembly 10, it flows more smoothly and evenly into the equipment through the coordinated guidance of the first vent 12 and the second vent 13, achieving a highly efficient and stable ventilation effect.

[0044] For example, the first vent 12 is disposed on the end plate 14, and the second vent 13 is disposed on the enclosure plate 15, with the second vent 13 offset from the ventilation structure 201 in the height direction Z. That is, airflow cannot directly flow into the second vent 13 via the ventilation structure 201. Based on this, in severe weather such as heavy rain, due to the height difference between the second vent 13 and the ventilation structure 201, rainwater entering the protective cavity 11 through the ventilation structure 201 will not flow directly to the second vent 13, thus preventing rainwater from entering the equipment through the second vent 13 to a certain extent and enhancing the waterproof performance of the ventilation assembly 10.

[0045] It should be noted that the accompanying drawings of this application only show an embodiment in which the first vent 12 is disposed on the end plate 14. In other embodiments not shown in the accompanying drawings of this application, one of the first vent 12 and the second vent 13 may also be disposed on at least one side plate 152. Alternatively, both side plates 152 may be provided with either the first vent 12 or the second vent 13.

[0046] Please refer to Figure 2 and Figure 4The second filter assembly 3 includes a second filter element 31 and a connecting structure 32. The second filter element 31 is disposed at the top of the fixed bracket 22 and covers the second vent 13. The connecting structure 32 is connected to the protective cover 1 and is located on the side of the second filter element 31 facing away from the fixed bracket 22. The connecting structure 32 and the fixed bracket 22 limit the second filter element 31 in the height direction Z, so that the second filter element 31 is firmly fixed in the height direction Z. That is, the second filter element 31 is supported at the top of the fixed bracket 22. The support of the fixed bracket 22 can ensure that the second filter element 31 will not sag or shift under the action of gravity. The connecting structure 32 limits the top of the second filter element 31, which can prevent the second filter element 31 from falling outward due to airflow impact or vibration. The two work together to make the position of the second filter element 31 stable and reliable inside the protective cover 1, and it is not easy to deform or loosen after long-term use, thus enhancing the reliability of the ventilation assembly 10.

[0047] During equipment operation, the heat generated by internal electronic components (such as charging modules and control units) causes the air to expand and rise, resulting in a natural phenomenon of hot air accumulating at the top of the cabinet. Therefore, by placing the second vent 13 on the wall surface of the protective cover 1 near the top edge 202, outside cold air can directly enter the higher hot air accumulation area inside the equipment through this location, fully contacting the hot air and completing heat exchange. This accelerates the exhaust of hot air and the replenishment of cold air without the need for additional power, thus improving heat dissipation efficiency.

[0048] Exemplarily, the enclosure 15 includes a bottom plate 151 near the bottom edge 203 and an opening near the top edge 202, which forms the second ventilation opening 13; that is, the enclosure 15 does not include a top plate. Of course, the enclosure 15 includes a bottom plate 151 near the bottom edge 203 and a top plate near the top edge 202, and the second ventilation opening 13 can be an opening structure formed on the top plate; this application does not specifically limit this. The second ventilation opening 13 communicates with the first ventilation opening 12, and the second filter element 31 is sandwiched between the two side plates 152. That is, the two side plates 152 limit the second filter element 31 in the width direction X, preventing the relative position of the second filter element 31 and the second ventilation opening 13 from shifting due to installation misalignment or equipment vibration, ensuring that the second filter element 31 can maintain its high-efficiency filtration function. The aforementioned first filter element 21 and second filter element 31 can be filter cotton or a filter screen.

[0049] During installation, the second filter element 31 can be precisely positioned simply by pushing it vertically into the gap between the two side plates 152. This eliminates the need for complex screw fastening, snap-fit ​​splicing, or adhesive fixing, reducing assembly difficulty and time costs.

[0050] Please refer to Figure 5 , Figure 7 and Figure 9As an example, the connecting structure 32 includes two connecting plates 321 spaced apart along the width direction X, and a pressure plate 322 connected between the two connecting plates 321. When the connecting plates 321 are connected to their corresponding side plates 152, the pressure plate 322 overlaps the side of the second filter element 31 facing away from the protective cavity 11. The pressure plate 322 is used to limit the risk of the second filter element 31 moving towards the top edge 202 in the height direction Z, preventing it from deviating from its original position due to accidental displacement. If the second filter element 31 moves towards the top edge 202, it may cause a deviation in its fit with the ventilation structure, affecting the normal passage of airflow and the filtration effect. The pressure plate 322 restricts its movement, ensuring that the second filter element 31 can continuously and effectively filter the air entering the equipment, maintaining the cleanliness of the air inside the equipment.

[0051] Please combine Figure 10 and Figure 12 One of the connecting plate 321 and the side plate 152 is provided with a snap-fit ​​groove 323, and the other is provided with a snap-fit ​​protrusion 324. The snap-fit ​​protrusion 324 is snapped into the snap-fit ​​groove 323. After the snap-fit ​​protrusion 324 is embedded in the snap-fit ​​groove 323, it can prevent the connecting plate 321 and the side plate 152 from horizontally sliding or loosening under dynamic loads such as airflow impact and vibration, ensuring the long-term reliability of the connection structure 32. The connecting plate 321 and the side plate 152 adopt a detachable connection method, and the connection structure 32 can be disassembled and assembled without the need for complicated tools or destructive operations. When it is necessary to clean or replace the second filter element 31, it is only necessary to separate the connection between the connecting plate 321 and the side plate 152 to remove the second filter element 31, which simplifies the maintenance process of the second filter assembly 3 and reduces the difficulty of manual operation and time costs.

[0052] Of course, the connection between the connecting plate 321 and the side plate 152 can also be detachable, such as by using clips, bolts or slots.

[0053] As an example, the connecting plate 321 is provided with a snap-fit ​​groove 323, and the side plate 152 is provided with a snap-fit ​​protrusion 324. The pressure plate 322 is bent towards the bottom edge 203 at both ends in the width direction X to form the connecting plate 321, and the two side plates 152 are confined between the two connecting plates 321. That is, the connecting plate 321 and the pressure plate 322 are integrally bent structures, eliminating the assembly steps of the independent connecting plate 321, so that the first fixing member 32200 can simultaneously have the dual functions of the pressure plate 322 (constrained in the thickness direction Y) and the connecting plate 321 (connected by the side plates 152) through simple bending.

[0054] The slot 323 extends through the connecting plate 321 along the width direction X, and its cross-sectional shape is approximately L-shaped, including mutually perpendicular and connected vertical slot segments (extending along the height direction Z) and horizontal slot segments (extending along the thickness direction Y). The horizontal slot segments extend through the sidewall of the connecting plate 321. Figure 10 and Figure 11 As shown, the connection plate 321 and the side plate 152 are assembled: the snap-fit ​​protrusion 324 snaps into the vertical groove of the snap-fit ​​groove 323, and under the action of gravity, the top of the snap-fit ​​protrusion 324 abuts against the top of the vertical groove, forming a limit in the height direction Z. In this way, the connection structure 32 can be prevented from loosening due to dynamic loads such as vibration and airflow impact during equipment operation, ensuring a reliable connection between the connection structure 32 and the side plate 152.

[0055] like Figure 12 As shown, when the second filter element 31 needs to be disassembled, simply lift the connecting structure 32 upwards, causing the snap-fit ​​protrusion 324 to move down along the vertical groove section to its intersection with the horizontal groove section. Then, as... Figure 13 As shown, moving the connecting structure 32 along the thickness direction Y allows the snap-fit ​​protrusion 324 to disengage from the horizontal groove section, thus quickly completing the disassembly of the second filter element 31. Similarly, when installing the second filter element 31, pushing the connecting structure 32 causes the snap-fit ​​protrusion 324 to move to the intersection of the horizontal and vertical groove sections under the guidance of the horizontal groove section. Then, under the action of gravity, the connecting structure 32 automatically moves downward until the snap-fit ​​protrusion 324 abuts against the top of the vertical groove section.

[0056] Please combine Figure 7 and Figure 9 The second filter element 31 has a first side portion 311 and a second side portion 312 disposed opposite each other along the thickness direction Y. The first side portion 311 is disposed closer to the door panel 20 relative to the second side portion 312. The battery pack also includes a limiting member 33. Both the connecting structure 32 and the limiting member 33 are connected to the protective cover 1 and are disposed on the side of the second filter element 31 facing away from the protective cavity 11. The connecting structure 32 and the limiting member 33 are disposed opposite each other along the thickness direction Y. The limiting member 33 can restrict the movement of the first side portion 311 in the height direction Z away from the protective cavity 11, and the connecting structure 32 can restrict the movement of the second side portion 312 in the height direction Z away from the protective cavity 11.

[0057] By employing the above method, the connecting structure 32 and the limiting member 33 respectively limit the second filter element 31 from both sides of the thickness direction Y, effectively eliminating the problem of uneven force that may be caused by unilateral limiting. On the one hand, the balanced limiting force on both sides can prevent local warping, wrinkling, or loosening of the filter element, ensuring that the second filter element 31 is tightly fitted with the covering surface of the second vent 13, maintaining a stable filtration gap, and preventing filtration failure or airflow short circuit due to displacement of the second filter element 31. On the other hand, the connecting structure 32 and the limiting member 33 can jointly resist dynamic loads such as airflow impact and vibration, maintaining a reliable fixed state during long-term use, thereby improving the structural stability of the second filter assembly 3.

[0058] The side of the enclosure 15 near the door panel 20 has a mounting flange 153 protruding outward toward the protective cover 1. A limiting member 33 is disposed on the portion of the mounting flange 153 near the door panel 20 and includes a plurality of limiting protrusions spaced apart along the width direction X. Alternatively, in some embodiments not shown in the accompanying drawings, the limiting member 33 may be a limiting sub-plate that protrudes from the mounting flange 153 along the thickness direction Y and extends along the width direction X, forming an elongated structure.

[0059] Among them, a support plate 154 is also provided on the part of the flange 153 near the door panel 20. The support plate 154 is located relative to the bottom edge 203 of the door panel 20 near the limiting member 33 (see label). Figure 7 The two sides are set apart, with the first side 311 supported on the support plate 154 and located within the interval. That is, the first side 311 is limited in the height direction Z by the support plate 154 and the limiting member 33, and the second side 312 is limited in the height direction Z by the fixing bracket 22 and the connecting structure 32.

[0060] As another example, the fixed bracket 22 has a support end plate 223 at one end facing the door panel 20. The support end plate 223 bends and extends away from the end plate 14 relative to the fixed bracket 22, thereby increasing its contact area with the second filter element 31 and providing more stable support for the second filter element 31. In some embodiments not shown in the accompanying drawings, the end of the support end plate 223 away from the fixed bracket 22 can extend to a length that contacts the mounting flange 153. By extending the support range, all-round support for the second filter element 31 in the thickness direction Y is achieved. Based on this, there is no need to additionally set the support plate 154 in the aforementioned embodiments, which simplifies the overall structure while still ensuring the stable installation of the second filter element 31.

[0061] In other embodiments of this application, a charging pile is also provided, such as... Figure 1 and Figure 14As shown, the charging pile includes a cabinet 30, a door panel 20, and a ventilation assembly 10. The door panel 20 is connected to the cabinet 30 and is located on the air inlet side 30a of the cabinet 30. A ventilation structure 201 connecting the outside and inside of the cabinet 30 is provided on the door panel 20. The ventilation assembly 10 is located on the wall of the door panel 20 facing the inside of the cabinet 30. Since the ventilation assembly 10 in this charging pile has the same technical features as the aforementioned ventilation assembly 10, both can solve the same technical problems and achieve the same technical effects, and will not be described in detail here.

[0062] The door panel 20, serving as the air intake side 30a of the cabinet 30, is in direct contact with the external environment. The ventilation structure 201 (such as louvers, perforations, grilles, etc.) can introduce fresh air from the outside immediately. The ventilation component 10 is arranged close to the inner wall of the door panel 20, allowing cold air from the outside to directly enter the ventilation component 10 after passing through the ventilation structure 201, and then enter the interior of the cabinet 30 through the ventilation component 10, thus improving heat dissipation efficiency.

[0063] like Figure 2 and Figure 14 As shown, the door panel 20 has a vertical height direction Z and a thickness direction Y. Multiple ventilation components 10 are arranged at intervals along the height direction Z on the wall surface of the door panel 20 facing the interior of the cabinet 30. The dimensions of adjacent protective covers 1 are unequal in the thickness direction Y. Therefore, the multiple ventilation components 10 arranged at intervals along the height direction Z can provide directional airflow to heating elements at different height levels inside the cabinet 30. Simultaneously, this dimensional difference provides additional operating space for the installation and removal of the first filter element 21. For example, when it is necessary to remove or reinstall the first filter element 21 from the ventilation component 10, there is no need to worry about the first filter element 21 hitting adjacent ventilation components 10, reducing operational obstacles and improving the convenience of installation and removal.

[0064] The protective cover 1 has an end plate 14 positioned opposite the door panel 20 in the thickness direction Y. In two adjacent protective covers 1, the distance between the end plate 14 of the protective cover 1 closer to the bottom edge 203 and the door panel 20 is D1, and the distance between the end plate 14 of the protective cover 1 farther from the bottom edge 203 and the door panel 20 is D2. Where 7mm ≤ D1 - D2 ≤ 20mm, that is, the difference between D1 and D2 ranges from 7mm to 20mm. Since the first filter element 21 is usually connected to the protective cover 1 through a top opening or a detachable structure, it needs to be pulled upwards in the height direction Z when removed. This design ensures that the gap variation between adjacent protective covers 1 is moderate. If the difference in distance between the end plate 14 of adjacent protective covers 1 and the door panel 20 is too small, it is easy for the filter element 21 to collide with the end plate 14 of the adjacent protective cover 1 during operation, causing deformation or damage. At the same time, it avoids the protective cover 1 occupying a large space within the cabinet 30 due to excessive gap differences, which is beneficial for improving the utilization rate of the cabinet space.

[0065] Specifically, since the distance D2 between the end plate 14 of the protective cover 1, which is far from the bottom edge 203, and the door panel 20 is relatively small, when viewed from the height direction Z, the upper protective cover 1 will not completely block the lower protective cover 1. At this time, during the process of pulling out the first filter element 21 in the bottom ventilation assembly 10, the first filter element 21 will not cause spatial interference with the upper protective cover 1 in the vertical movement path, ensuring that the first filter element 21 can be smoothly removed from the top opening or detachable structure of the protective cover 1, avoiding the risk of operation obstruction or scratch damage to the first filter element 21 due to the obstruction of the upper protective cover 1.

[0066] Please continue to refer to Figure 2 , Figure 3 and Figure 14 A water-retaining eave 204 is provided on the wall of the door panel 20 facing the interior of the cabinet 30. The water-retaining eave 204 is located on the side of the ventilation structure 201 near the top edge 202. During the waterproof performance test of the cabinet 30, water is sprayed onto the cabinet 30 from different directions. The water-retaining eave 204 can block the water flow from bottom to top, causing it to deviate from the opening area of ​​the first ventilation opening 12, which helps to improve the waterproof performance of the charging pile.

[0067] For example, from the door panel 20 to the end panel 14, the water-blocking eaves 204 extend toward the bottom edge 203, and its extension trajectory intersects the path of the water flow injected from bottom to top, so as to better block the water flow injected from bottom to top.
