Description

Technical Field

[0001] This utility model relates to the field of charging pile technology, specifically to a filter component and a charging pile. Background Technology

[0002] Charging piles and other power equipment are generally equipped with fans for heat dissipation. In order to prevent the fans from sucking in dust, moisture and other impurities from the air into the equipment, filter components are usually installed to block and filter these impurities to ensure the stable operation of the internal components of the equipment.

[0003] In the prior art, a utility model patent with publication number "CN219191950U" and titled "Charging pile chassis door structure and charging pile for easy filter replacement" discloses a filter component, such as... Figure 1 As shown, it includes a ventilation slot 2', a grille 3', a filter element 4', and a filter element fixing cover 5'. The ventilation slot 2' is located on the main body 1' of the chassis door, and the grille 3' is installed inside the ventilation slot 2'. The filter element fixing cover 5' is installed on the main body 1' of the chassis door by multiple screws, thereby allowing the filter element 4' to be installed inside the ventilation slot 2'. The existing filter assembly still has certain problems: 1. The middle part of the filter element fixing cover 5' is mesh, which can prevent the filter element 4' from being sucked inward when the fan is working, but its cost is high, especially when applied to large-sized charging piles; moreover, its adaptability is poor; 2. The filter element fixing cover 5' is installed by screws, which is troublesome to assemble and inconvenient to disassemble and replace. Utility Model Content

[0004] This utility model addresses the technical problems of high cost and poor adaptability in the filter element installation structure of existing filter components. It proposes a filter component and charging pile, in which the edge of the filter element is pressed by the cooperation of a first clamping member on the first frame and a second clamping member on the second frame. Moreover, the first and second clamping members can be formed as universal parts, which can be flexibly installed to accommodate charging piles and other equipment of various sizes, with good adaptability and low overall cost.

[0005] The technical solution of this utility model:

[0006] A filtering component, comprising:

[0007] A first frame, on which a plurality of first clamping components are fixedly installed;

[0008] The second frame has multiple second clamping components fixedly installed on it, and the second clamping components are arranged in a one-to-one correspondence with the first clamping components;

[0009] A filter element is disposed between the first frame and the second frame, and the edges of the filter element are correspondingly pressed by a plurality of first clamping members and second clamping members.

[0010] Furthermore, when the filter element is compressed, there is a drainage gap between the bottom of the first frame and the bottom of the second frame.

[0011] Furthermore, the first clamping member includes a first clamping surface for cooperating in clamping the filter element, the first clamping surface protruding from the first frame; the second clamping member includes a second clamping surface for cooperating in clamping the filter element, the second clamping surface protruding from the second frame.

[0012] Furthermore, the first clamping member is provided with a positioning protrusion, and the second clamping member is provided with a corresponding positioning groove;

[0013] Alternatively, the first clamping member may have a positioning groove, and the second clamping member may have a corresponding positioning protrusion.

[0014] Furthermore, the filter assembly is used to install on the target housing, and during installation, the second frame is closer to the target housing than the first frame; the target housing is provided with a plurality of fastening buckles, and the first frame is provided with a plurality of corresponding hooks.

[0015] Furthermore, a seal is also pressed between the second frame and the target housing.

[0016] Furthermore, the second frame is provided with rivet screws corresponding to each of the second clamping members, and the heads of the rivet screws do not protrude from the side of the second frame facing the sealing member.

[0017] Furthermore, the first frame and the second frame are sheet metal parts, and the first clamping part and the second clamping part are plastic parts.

[0018] Furthermore, the filter element is filter cotton.

[0019] In another aspect, this utility model provides a charging pile, which includes the filtering component described in any one of the above.

[0020] After adopting the above technical solution, the filter component and charging pile provided by this utility model have the following beneficial effects compared with the prior art: In this embodiment, multiple first clamping parts installed on the first frame and multiple second clamping parts installed on the second frame are used to press the edge of the filter component, which can prevent the filter component from being sucked inward when the fan is working; in addition, the first and second clamping parts can be formed as universal parts with good adaptability. For example, corresponding to different target shell sizes and air outlet areas, the appropriate number of first and second clamping parts can be selected as needed, without having to make a complex fixed cover each time as in the prior art, thus reducing the overall cost.

[0035] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0036] Example 1:

[0037] like Figure 2-4 As shown, this embodiment provides a filter assembly, which includes a first frame 1 and a second frame 2. The first frame 1 is hollow in the center and is preferably square. Multiple first clamping members 4 are fixedly installed on its four sides. The first clamping members 4 can be connected by welding, fastener assembly, or other methods. Similarly, the second frame 2 is hollow in the center and is preferably square. Multiple second clamping members 5 are fixedly installed on its four sides. The second clamping members 5 can be connected by welding, fastener assembly, or other methods. The first clamping members 4 are located on the side of the first frame 1 facing the second frame 2, and the second clamping members 5 are located on the side of the second frame 2 facing the first frame 1. The second clamping members 5 and the first clamping members 4 are arranged in a one-to-one correspondence.

[0038] Furthermore, the filter assembly also includes a filter element 3, which is preferably square. The filter element 3 is disposed between the first frame 1 and the second frame 2. When the first frame 1 moves toward the second frame 2, the four edges of the filter element 3 can be correspondingly pressed by multiple first pressing members 4 and second pressing members 5. The center of the filter element 3 can filter impurities in the air when air is introduced. The pressing position of the filter element 3 can be set as needed, for example... Figure 2-3 As shown, in this embodiment, the filter element 3 is pressed at its four corners and the middle of its four sides. The filter element 3 is preferably filter cotton.

[0039] Thus, the filter assembly provided in this embodiment, through the cooperation of multiple first clamping parts 4 installed on the first frame 1 and multiple second clamping parts 5 installed on the second frame 2 to clamp the edge of the filter element 3, can prevent the filter element 3 from being sucked inward when the fan is working. Furthermore, the first clamping parts 4 and second clamping parts 5 can be formed as universal parts, with good adaptability. For example, corresponding to different sizes of air outlet areas, the appropriate number of first clamping parts 4 and second clamping parts 5 can be selected as needed, without the need to manufacture complex fixed covers each time as in the prior art, thus reducing overall costs. Moreover, preferably, the first clamping parts 4 and second clamping parts 5 can be made of plastic parts, manufactured by injection molding, resulting in lower costs; preferably, the first frame 1 and the second frame 2 are made of sheet metal parts, resulting in lower costs. In addition, this embodiment uses a multi-point clamping method, which can prevent the filter element 3, such as filter cotton with a certain degree of elasticity, from shifting during clamping installation, facilitating installation; and multiple localized clamping points can prevent excessive overall deformation of the filter element 3, such as excessive arching in the middle, which could lead to filtration failure or reduced service life.

[0040] To drain the filter element 3 and prevent excessive water accumulation from affecting drying or even entering the target housing 7 and affecting the normal operation of the device, such as... Figure 6-8 As shown, in this embodiment, when the filter element 3 is compressed, there is a drainage gap 6 between the bottom of the first frame 1 and the bottom of the second frame 2, allowing water to drip out through this drainage gap 6. In addition to the mounting edges corresponding to the first clamping element 4 and the second clamping element 5, the first frame 1 and the second frame 2 also include flanges around their perimeter. When compressed, the drainage gap 6 exists between the flanges at the bottom of the first frame 1 and the flanges at the bottom of the second frame 2.

[0041] Preferably, the first clamping member 4 includes a first clamping surface 41 for clamping the filter element 3, the first clamping surface 41 protruding from the first frame 1, that is, necessarily protruding from the flange on the bottom surface of the first frame 1; the second clamping member 5 includes a second clamping surface 51 for clamping the filter element 3, the second clamping surface 51 protruding from the second frame 2, that is, necessarily protruding from the flange on the bottom surface of the second frame 2. Thus, when the filter element 3 is clamped, there will inevitably be a drainage gap 6 slightly larger than a set size between the flange on the bottom surface of the first frame 1 and the flange on the bottom surface of the second frame 2, ensuring reliable drainage. It should be noted that the thickness of the filter element 3 at its four edges is smaller than the thickness at its center, which is used to illustrate the thickness after clamping; and although the thickness of the filter element 3 at its four edges is small in the figure, in reality, only a few localized areas at its four edges are clamped.

[0042] In order to position the first frame 1 and the second frame 2 during installation, such as Figure 4 As shown, in this embodiment, a positioning protrusion 42 is provided on the first pressing surface 41 of the first pressing member 4, and a corresponding positioning groove 52 is provided on the second pressing surface 51 of the second pressing member 5. When the first frame 1 is pressed against the second frame 2 from front to back, the positioning protrusion 42 enters the positioning groove 52, which can realize the positioning of the first frame 1 and the second frame 2. The two will not move apart except in the front-back direction, thus facilitating subsequent installation. In this embodiment, the positioning protrusion 42 and positioning groove 52 are provided on the first pressing member 4 and the second pressing member 5, which is easier and cheaper than providing them on the first frame 1 and the second frame 2; moreover, multi-point positioning makes the positioning effect better. Of course, in other embodiments, the positioning groove 52 can also be provided on the first pressing member 4, and the positioning protrusion 42 can be correspondingly provided on the second pressing member 5. In addition, the filter element 3 needs to be provided with a through hole so that the positioning protrusion 42 can pass through.

[0043] like Figure 2 , 5As shown in Figure 7, the filter assembly of this embodiment can be installed on the target housing 7 of equipment such as charging piles. The target housing 7 has a mounting surface 71 with an opening (air vent) formed on it. During installation, the second frame 2 is closer to the mounting surface 71 of the target housing 7 than the first frame 1. The target housing 7 is provided with a plurality of fastening buckles 72, and the first frame 1 is provided with a plurality of hooks 11. The hooks 11 can be formed by bending. After the first frame 1 is pushed toward the second frame 2, the fastening part of the fastening buckle 72 flips and engages with the hook 11, thereby pressing the filter 3 firmly in place. In this embodiment, the fastening buckles 72 are preferably four, and the hooks 11 on the first frame 1 are also preferably four. The fastening buckles 72 and hooks 11 are preferably located near the sides of the first pressing member 4 and the second pressing member 5 for better pressing. Of course, in other embodiments, the number and position of the fastening buckles 72 and the hooks 11 on the first frame 1 can be set as needed.

[0044] Furthermore, in this embodiment, a sealing element 8 is also pressed between the second frame 2 and the target housing 7. For example... Figure 4 As shown, the second clamping member 5 has two second mounting edges 53, which are used to connect with the second frame 2. The second mounting edges 53 are recessed inward into the second clamping surface 51. Specifically, the second frame 2 has rivet screws 21 corresponding to the second mounting edges 53 of each second clamping member 5. The rivet screws 21 are pre-riveted onto the second frame 2, and the heads of the rivet screws 21 do not protrude from the side of the second frame 2 facing the seal 8 to ensure reliable clamping of the seal 8 by the second frame 2. The second mounting edge 53 has a through hole through which the rivet screw 21 can pass, and then it is fixed with a nut 22. The first clamping member 4 has two first mounting edges 43, which are used to connect with the first frame 1. The first mounting edges 43 are recessed inward into the first clamping surface 41. Since there is no seal 8 on the front side of the first frame 1, the first clamping member 4 and the first frame 1 can also be installed using a simpler method such as rivet screws 12.

[0045] The filter assembly in this embodiment makes it easy to replace the filter element 3. First, unlock each fixing buckle 72 to make the first frame 1 free, and remove the first frame 1 to take out the original filter element 3. Then, the new filter element 3 can be laid flat. The maintenance personnel position the first clamping member 4 on the first frame 1 and the second clamping member 5 on the second frame 2 and press the new filter element 3. Then, lock the fixing buckle 72 back to the hook 11 on the first frame 1 to complete the replacement and installation of the filter element 3.

[0046] As can be seen from the above, the filter assembly provided in this embodiment uses a first clamping member on the first frame and a second clamping member on the second frame to clamp the edge of the filter element. Moreover, the first clamping member and the second clamping member can be formed as universal parts, which can be flexibly installed to fit charging piles and other equipment of various sizes. It has good adaptability and low overall cost. It also has the advantages of natural drainage and convenient disassembly and maintenance.

[0047] Example 2:

[0048] This embodiment provides a charging pile, which includes a target housing 7, on which a filter assembly as described in Embodiment 1 is installed; a fan is provided inside the target housing 7, and the filter assembly filters the air when it is introduced.

[0049] In other embodiments, the filter assembly can also be adapted to be installed in other devices, and the present invention does not limit this.

[0050] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
