[0002] Charging stations contain heat-generating components such as power modules and control systems, requiring forced air cooling for heat dissipation. However, unfiltered air entering the charging station can damage internal circuitry, necessitating the installation of filters at the air intake of the charging station's cooling structure. Current filters are typically secured with screws or pressure plates, requiring a screwdriver for installation and removal, making the process inconvenient. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an air filter structure that is easy to disassemble and assemble, in view of the above-mentioned defects of the prior art.

[0004] The technical solution adopted by this utility model to solve its technical problem is: to construct an air filter structure, which is applied to a charging pile, including a louver assembly and a filter assembly; the louver assembly includes a base plate, a first guide and a second guide mounted on the base plate, the first guide is provided with a first positioning pin, and the second guide is provided with a second positioning pin. The filter assembly is provided with a first positioning hole, which is directly opposite to the first positioning pin; the filter assembly is provided with a second positioning hole, which is directly opposite to the second positioning pin. When the first and second sides of the filter assembly are inserted along the first guide and the second guide respectively, the first positioning pin is inserted into the first positioning hole, and the second positioning pin is inserted into the second positioning hole to fix the filter assembly. In the air filtration structure described in this utility model, the first guide member and the second guide member are arranged horizontally relative to each other; The orthographic projections of the first positioning pin and the second positioning pin on the projection plane parallel to the first guide and the second guide do not completely overlap; The orthographic projections of the first positioning hole and the second positioning hole on the projection plane parallel to the first guide and the second guide do not completely overlap.

The first positioning hole and the second positioning hole do not overlap in their orthographic projections on the projection plane parallel to the first guide and the second guide, and are spaced apart by a set distance.

[0006] In the air filtration structure described in this utility model, the first guide and the second guide are U-shaped guide grooves; the first positioning pin and the second positioning pin are elastically riveted and fixed to the first guide and the second guide, respectively.

Detailed Implementation

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0015] Figure 1 This is an exploded view of the air filter structure of this utility model. Figure 2 This is an assembly diagram of the air filter structure of this utility model. Figure 3 This is a schematic diagram of the anti-reverse design of the air filter structure of this utility model. Figure 4 yes Figure 3 Enlarged view of the structure of part A. Figure 5 This is a side view of the air filter structure of this utility model. The following will be combined with... Figures 1-5 The air filter structure of this utility model is described below.

[0016] like Figures 1-5 As shown, the air filtration structure of this utility model is applied to a charging pile, including a louver assembly 1 and a filter assembly 2. The louver assembly 1 includes a base plate 10, a guide 41 and a guide 42 mounted on the base plate 10. The guide 41 is provided with a positioning pin 51, and the guide 42 is provided with a positioning pin 52. The filter assembly 2 is provided with a positioning hole (not shown) opposite the positioning pin 51, and a positioning hole 82 opposite the positioning pin 52. When the first side and the second side of the filter assembly 2 are inserted along the guide 41 and the guide 42 respectively, the positioning pin 51 is inserted into the positioning hole, and the positioning pin 52 is inserted into the positioning hole 82 to fix the filter assembly 2. The air filtration structure of this utility model includes a louver assembly comprising a base plate, a first guide member and a second guide member mounted on the base plate. The first guide member has a first positioning pin, and the second guide member has a second positioning pin. The filter assembly has a positioning hole facing the first positioning pin and a second positioning hole facing the second positioning pin. Therefore, when installing the filter assembly, the first and second sides of the filter assembly can be inserted along the first and second guide members respectively, and then the first positioning pin is inserted into the positioning hole, and the second positioning pin is inserted into the second positioning hole, thereby fixing the filter assembly. The entire process does not require screws or pressure plates, thus eliminating the need for screwdrivers and other tools, making assembly and disassembly simple.

[0017] In a preferred embodiment of this utility model, such as Figures 1-2 As shown, guide 41 and guide 42 are horizontally arranged relative to each other; the orthographic projections of positioning pin 51 and positioning pin 52 on the projection plane parallel to guide 41 and guide 42 do not completely overlap. Since positioning pin 51 and positioning pin 52 are respectively aligned with positioning hole 82, the orthographic projections of positioning hole 82 on the projection plane parallel to guide 41 and guide 42 do not completely overlap.

[0018] It can be understood here that the non-complete overlap of the orthographic projections of the positioning pins 51 and 52 on the projection plane parallel to the guide members 41 and 42 means that they are not completely on the same straight line, for example, they are slightly offset. More preferably, the orthographic projections of the positioning pins 51 and 52 on the projection plane parallel to the guide members 41 and 42 do not overlap and are spaced apart by a set distance, that is, the positioning pins 51 and 52 are offset from each other in the horizontal direction and spaced apart by a certain distance, such as... Figure 2 As shown. Similarly, since the positioning pin 51 and the positioning pin 52 are respectively aligned with the positioning hole and the positioning hole 82, the orthographic projections of the positioning hole and the positioning hole 82 on the projection plane parallel to the guide member 41 and the guide member 42 do not overlap and are spaced apart by a set distance from each other.

[0019] This design prevents the filter assembly 2 from being installed backwards. If installed backwards, positioning pin 51 cannot align with positioning hole 82, and positioning pin 52 also cannot align with positioning hole 82. Therefore, it cleverly achieves anti-reverse installation. This anti-reverse installation structure fundamentally avoids functional failures caused by human error, improving the reliability of operation and maintenance.

[0020] Further as Figures 1-5As shown, the guide 41 and the guide 42 are U-shaped guide grooves; the positioning pins 51 and 52 are elastically riveted to the guide 41 and the guide 42, respectively. By elastically riveting the positioning pins 51 and 52, during assembly and disassembly, only slight force is needed to insert the first and second sides of the filter assembly along the first and second guides, respectively. Then, the first positioning pin is inserted into the positioning hole, and the second positioning pin is inserted into the second positioning hole, thereby fixing the filter assembly. Assembly and disassembly are simple. Further as... Figures 1-5 As shown, a set of blades 11 are obliquely arranged between the guide members 41 and 42, and the opening between adjacent blades 11 forms the air inlet 30 of the louver assembly 1. A water guide groove 20 is provided at one end of the guide members 41 and 42; the water guide groove 20 is a U-shaped groove, and the guide members 41 and 42 are accommodated in the water guide groove 20. This facilitates the discharge of water vapor entering through the air inlet 30.

[0021] In a preferred embodiment of this utility model, the substrate 10, the water guide groove 20, the blade 11, and the U-shaped guide groove 40 can be formed by sheet metal bending and welding; the elastic pressing and positioning pin 50 is horizontally staggered and pressed and fixed on the U-shaped guide groove 40, which can realize the foolproof design of misinstallation and misalignment. The elastic pressing and positioning pin 50 will not loosen when pulled. The positioning hole 80 cooperates with the elastic pressing and positioning pin 50 to achieve precise positioning. The elastic pressing and positioning pin 50 can be pulled out by hand without tools.

[0022] The filter assembly 2 includes an air filter unit 60 and a frame 70 surrounding the air filter unit 60. For example... Figures 1-2 As shown, the frame is a rectangular frame, the positioning hole is located on the first side of the frame 70, and the positioning hole 82 is located on the second side of the frame 70; the first side and the second side are parallel to each other. Two handles 90 are provided on the third side of the frame 70, the third side is perpendicular to the first side and the second side, and is away from the water guide channel 20. Due to the handles 90, the cooperation between the handles 90, the positioning pins 51 and 52 and the positioning holes 82 respectively can realize the dual quick-release design of "elastic positioning pin + pull-out module", which simplifies the maintenance process to the extreme and greatly reduces the workload and time cost of maintenance personnel.

[0023] The air filter unit 60 includes a filter screen, which is detachably installed in the frame 70. The filter screen is replaceable, therefore the design of the air filter unit 60 and frame 70 allows for flexible use of filters of different materials and precision to adapt to various complex environments, from ordinary cities to deserts and coastal areas, thus improving the product's market adaptability. The air filter unit 60 can be removed for cleaning and replacement.

Furthermore, various modifications can be made to this utility model for specific situations or materials without departing from its scope. Therefore, this utility model is not limited to the specific embodiments disclosed, but should include all embodiments falling within the scope of the claims of this utility model.

[0025] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
