Description

Technical Field

[0001] This utility model relates to the field of charging pile technology, and in particular to a louvered structure and a charging pile. Background Technology

[0002] In related technologies, air-cooled DC charging piles typically employ a louvered structure to achieve ventilation and heat dissipation while meeting waterproofing requirements. The louvers on the charging pile cabinet prevent rainwater and other external factors from entering the cabinet, while allowing air circulation to cool the internal equipment. However, current mainstream louver manufacturing methods have significant limitations.

[0003] Most louvered windows are typically assembled from multiple individually manufactured louver blades. Specifically, each louver blade is first made into an independent component, then assembled to form a complete louvered window assembly, which is then installed onto the charging station cabinet. These louver blades are usually made of aluminum profiles or formed by bending sheet metal. However, regardless of the material or processing method used, assembling the louver blades requires a significant amount of manpower and multiple processes.

[0004] The aforementioned venetian blinds have several drawbacks. First, because the venetian blind assembly involves numerous independent slat components, its overall structure is quite complex, with a large number of parts, leading to a cumbersome production process. Each slat must be assembled individually, which not only increases labor costs but also complicates the processing steps, affecting production efficiency. Furthermore, the manual assembly process is time-consuming, further contributing to the high overall manufacturing cost.

[0005] Secondly, the louvers produced using related technologies typically have low protection ratings, mostly only reaching IPX4 (Ingress Protection). This means limited waterproofing performance, making them ineffective against harsh outdoor environments. In practical applications, this deficiency may lead to damage to internal components of the charging station from external moisture, reducing equipment reliability and lifespan. Therefore, improving production efficiency, reducing costs, and enhancing the protection rating of louvers are urgent issues that need to be addressed. Utility Model Content

[0006] The main purpose of this utility model is to provide a louver structure and a charging pile, so as to at least solve the technical problems of poor waterproof effect, complex overall structure, large number of louver components, cumbersome production process, long time-consuming manual assembly process, and high overall manufacturing cost in the related technology.

[0007] To achieve the above objectives, the present invention provides the following technical solutions:

[0008] In a first aspect, this utility model provides a louvered structure for installation on a charging pile with a cabinet shell. The louvered structure includes a first plate, a second plate, and a third plate near a heat dissipation vent on the cabinet shell, arranged sequentially.

The second plate has a third end face and a fourth end face facing away from each other. The third end face faces the second end face and is provided with a second channel assembly for gas flow. The fourth end face is provided with a second blade assembly. The fifth end face of the first plate faces the fourth end face and is provided with a third blade assembly and a third channel assembly for gas flow. A first cavity is formed between the fifth end face and the fourth end face. The second blade assembly and the third blade assembly are staggered and spaced within the first cavity.

[0009] Based on the first aspect, the first blade assembly includes a plurality of first blade structures, and the first channel assembly includes a plurality of first gas channels; the plurality of first blade structures and the plurality of first channel openings are arranged linearly and alternately in the length direction of the third plate.

[0010] Based on the first aspect, the second blade assembly includes a plurality of second blade structures, and the second channel assembly includes a plurality of second gas channels; the plurality of second blade structures and the plurality of second gas channels are arranged in a linear staggered pattern along the length of the second plate.

[0012] Based on the first aspect, the louver structure further includes a louver mounting housing having a second cavity for fixing to the cabinet housing, wherein the first plate, the second plate, and the third plate are disposed within the second cavity.

[0013] Based on the first aspect, the plurality of third gas channels, the plurality of second gas channels, and the plurality of first gas channels are distributed in an alternating manner within the cabinet housing, forming at least one gas heat dissipation channel for gas to flow in a curved manner.

[0014] Based on the first aspect, a plurality of second blade structures and a plurality of third blade structures are staggered and spaced within the first cavity, forming at least one liquid guide channel for the liquid to flow in a curved manner toward the bottom of the louvered shell.

[0015] Based on the first aspect, the louver mounting housing has a heat dissipation vent on the surface near the first plate.

[0016] Based on the first aspect, the louver structure further includes a first reinforcing component and a second reinforcing component. One end of the first reinforcing component is fixed to the third plate and the other end is fixed to the second plate. One end of the second reinforcing component is fixed to the third plate and the other end is fixed to the second plate.

[0017] A second aspect of this utility model provides a charging pile, including a cabinet shell with heat dissipation vents and a louvered structure as described in any of the first aspects; the louvered structure is installed inside the cabinet shell and close to the heat dissipation vents.

[0018] The louvered structure and charging pile of this invention, on the one hand, form a multi-layered, staggered blade assembly and channel assembly by sequentially arranging a first plate, a second plate, and a third plate, effectively reducing the risk of external moisture entering the cabinet and enhancing overall waterproof performance (at least IPX5 waterproof rating) while achieving effective ventilation and heat dissipation.

Since the blades do not need to be assembled individually, the overall assembly efficiency is also significantly improved. Attached Figure Description

[0028] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 This embodiment provides a louvered structure 20, which is installed on a charging pile with a cabinet shell 10. The louvered structure 20 includes a first plate 203, a second plate 202 and a third plate 201 arranged sequentially along its thickness direction. The third plate 201 is the plate closest to the heat dissipation vent 101 on the cabinet shell 10 among the three plates, and the three plates are parallel and there is a gap between adjacent plates.

[0029] Specifically, the third plate 201 has a first end face 2013 and a second end face 2014 facing away from each other. The first end face 2013 faces the heat dissipation vent 101 and is provided with a first blade assembly and a first channel assembly for gas flow. The third plate 201, being the plate closest to the heat dissipation vent 101, guides and diverts internal and external air through the first blade assembly and the first channel assembly, providing heat dissipation. Additionally, the first blade assembly also acts as a barrier against liquid entering through the heat dissipation vent 101, providing a certain degree of waterproofing.

[0030] Specifically, the second plate 202 has a third end face 2023 and a fourth end face 2024 facing away from each other. The third end face 2023 faces the second end face 2014 and has a second channel assembly for gas flow. The fourth end face 2024 is provided with a second blade assembly.

[0031] Specifically, the first plate 203 has a fifth end face 2033 and a sixth end face 2034 facing away from each other. The fifth end face 2033 faces the fourth end face 2024 and is provided with a third blade assembly and a third channel assembly for gas flow. A first cavity 500 is formed between the fifth end face 2033 and the fourth end face 2024, and the second blade assembly and the third blade assembly are staggered and distributed in the first cavity 500.

[0032] It should be noted that the second and third blade assemblies are not simply arranged neatly in the first cavity 500, but are arranged in an alternating manner to form an interlaced arrangement. Specifically, the second blade assembly is arranged linearly on one side of the first cavity 500, and the third blade assembly is arranged linearly on the other side of the first cavity 500, ultimately resulting in an alternating distribution of the two blade assemblies on the left and right sides of the first cavity 500.

[0033] Optionally, the first plate 203, the second plate 202, and the third plate 201 are all metal plates, and all are stamped out by a mold (CNC punching machine). Since each plate is equipped with a blade assembly composed of multiple blade structures, when assembling the louver structure, fixing a metal plate with its own louver blades is equivalent to fixing several louver blades at once, which greatly reduces the number of constituent parts and improves assembly efficiency.

[0034] The louver structure 20 of this embodiment, on the one hand, forms a multi-layered, staggered blade assembly and channel assembly by sequentially arranging a first plate 203, a second plate 202, and a third plate 201, effectively reducing the risk of external moisture entering the cabinet and enhancing overall waterproof performance (at least IPX5 waterproof rating) while achieving effective ventilation and heat dissipation. On the other hand, compared to the method in related technologies that requires individual blade molding and assembly, the blade assembly of this utility model is integrally stamped from a single metal plate, allowing multiple blades to be stamped at once, thereby reducing production steps. Since the blades do not need to be assembled individually, the overall assembly efficiency is also significantly improved.

[0035] In one embodiment of this invention, the first blade assembly includes a plurality of first blade structures 2011, and the first channel assembly includes a plurality of first gas channels 2012. The plurality of first blade structures 2011 are linearly arranged on the third plate 201 with approximately the same spacing between adjacent first blade structures 2011, and the plurality of first gas channels 2012 are linearly arranged on the third plate 201. Simultaneously, the first blade structures 2011 and the first gas channels 2012 are arranged in a regularly staggered pattern. Thus, the plurality of first blade structures 2011 and the plurality of first channel openings are linearly staggered along the length of the third plate 201. That is, by providing multiple heat dissipation channels for gas flow, and based on the inclined blade structure, the multiple heat dissipation channels can respectively block dust particles and water droplets, improving the waterproof performance of the charging pile cabinet. This achieves first-stage ventilation, heat dissipation, and waterproof performance at the location near the heat dissipation vent 101 on the charging pile cabinet shell 10.

[0036] In one embodiment of this invention, the second blade assembly includes multiple second blade structures 2021, and the second channel assembly includes multiple second gas channels 2022. The multiple second blade structures 2021 and the multiple second gas channels 2022 are arranged linearly and alternately along the length of the second plate 202. That is, by providing multiple heat dissipation channels for gas flow, and based on the inclined blade structure, the multiple heat dissipation channels can respectively block dust particles and water droplets, thereby improving the waterproof performance of the charging pile cabinet, thus achieving a second stage of ventilation, heat dissipation, and waterproof performance in the middle position of the charging pile cabinet.

[0037] In one embodiment of this invention, the third blade assembly includes multiple third blade structures 2031, and the third channel assembly includes multiple third gas channels 2032. The multiple third blade structures and multiple third gas channels are arranged linearly and alternately along the length of the first plate 203. That is, by providing multiple heat dissipation channels for gas flow, and based on the inclined blade structure, dust particles and water droplets can be blocked by the multiple heat dissipation channels respectively, improving the waterproof performance of the charging pile cabinet, thereby achieving a third stage of ventilation, heat dissipation, and waterproof performance at the innermost part of the charging pile cabinet.

[0038] In one embodiment of this invention, the louver structure further includes a louver mounting housing 30 with a second cavity for fixing to the cabinet shell 10. The first plate 203, the second plate 202, and the third plate 201 are disposed within the second cavity. The main function of the louver mounting housing 30 is to support and protect the three plates inside the louver structure, while securely mounting the louver structure to the cabinet shell 10 of the charging pile. The second cavity provides a closed space, allowing the first plate 203, the second plate 202, and the third plate 201 to be accurately positioned, and preventing component displacement or damage due to vibration or other external forces during operation.

[0039] In one embodiment of this invention, multiple third gas channels 2032, multiple second gas channels 2022, and multiple first gas channels 2012 are staggered and spaced within the cabinet housing 10, forming at least one gas cooling channel 50 for curved gas flow. Specifically, this structural design aims to establish a curved gas cooling channel 50 with the flow direction: from the third gas channel 2032 to the second gas channel 2022, from the second gas channel 2022 to the first gas channel 2012, and from the first gas channel 2012 to the heat dissipation vent 101. This maximizes airflow efficiency and heat dissipation performance, allowing heat accumulated inside the charging pile to flow from the third gas channel 2032 to the second gas channel 2022, the first gas channel 2012, and the gas cooling channel 50 to be discharged from the charging pile. The staggered arrangement of the multiple gas channels guides the air in a curved flow path as it flows through the entire louver structure, increasing the distance and time of airflow and thus more effectively dissipating heat inside the cabinet.

[0040] In one embodiment of this invention, multiple second blade structures 2021 and multiple third blade structures 2031 are staggered and spaced within the first cavity 500, forming at least one liquid guiding channel 60 for the liquid to flow in a curved manner towards the bottom 302 of the louvered housing. Specifically, this liquid guiding channel 60 can effectively guide the liquid entering the louvered structure to drain out towards the bottom 302 of the louvered housing along a specific path, further enhancing the drainage function and thus preventing liquid from entering the cabinet and damaging the equipment.

[0041] In one embodiment of this invention, the louver mounting housing 30 has a housing heat dissipation vent 301 on its surface near the first plate 203. The housing heat dissipation vent 301 further promotes airflow between the inside and outside of the louver structure, enabling more efficient exhaust of internal hot air.

[0042] In one embodiment of this invention, the louver structure further includes a first reinforcing component 204 and a second reinforcing component 205. One end of the first reinforcing component 204 is fixed to the third plate 201, and the other end is fixed to the second plate 202. One end of the second reinforcing component 205 is fixed to the third plate 201, and the other end is fixed to the second plate 202. The arrangement of these two reinforcing components improves the stability between the third plate 201 and the second plate 202, thereby enhancing the mechanical strength and durability of the entire louver structure.

[0043] This embodiment also provides a charging pile, which includes a cabinet shell with heat dissipation vents and a louvered structure. The louvered structure is installed inside the cabinet shell and close to the heat dissipation vents. In this embodiment, the charging pile forms a multi-layered, staggered blade assembly and channel assembly through a first plate 203, a second plate 202, and a third plate 201 arranged sequentially. This effectively reduces the risk of external moisture entering the cabinet, enhancing overall waterproof performance (at least IPX5 waterproof rating) while achieving effective ventilation and heat dissipation. Furthermore, compared to related technologies that require individual blade forming and assembly, the charging pile's blade assembly is integrally stamped from a single metal plate. Multiple blades can be stamped at once, reducing production steps. Since the blades do not need to be assembled individually, the overall assembly efficiency of the charging pile is improved.

[0044] The specific embodiments of the utility model have been described in detail above, but they are only examples, and the utility model is not limited to the specific embodiments described above. For those skilled in the art, any equivalent modifications or substitutions to the utility model are also within the scope of the utility model. Therefore, all equivalent transformations, modifications, and improvements made without departing from the spirit and principles of the utility model should be covered within the scope of the utility model.
