Description

Technical Field

[0001] This utility model relates to the field of charging pile technology, and more specifically, to a column-free double-door waterproof structure and a cabinet using the column-free double-door waterproof structure. Background Technology

[0002] Outdoor charging stations are devices installed in outdoor environments to provide power to users. Currently, charging stations on the market are rapidly developing towards larger capacity and higher power. To minimize the footprint of charging stations, manufacturers are trying to reduce the size of the charger's frame while increasing its power output. The charger includes internal components and a cabinet. Since the cabinet contains numerous components, miniaturizing it leads to a complex internal component layout. Furthermore, because most outdoor charging stations are installed outdoors, the cabinet is typically required to have good waterproof capabilities to prevent safety hazards such as electrical leaks caused by water ingress.

[0003] Currently, outdoor charging station cabinets on the market typically use a central support column in the middle of the front panel to position the left and right cabinet doors, and waterproof components are installed on the central support column or the left and right cabinet doors to provide waterproof protection when the doors are closed. In this case, waterproofing is required not only at the joint between the left and right cabinet doors and the central support column, but also at the joint between the left and right cabinet doors themselves, resulting in a large waterproofing area and significant challenges. Secondly, when water leaks from the joint between the cabinet doors and the central support column, the water will flow along the surface of the central support column into the cabinet's interior, thus compromising the cabinet's waterproofing effectiveness. Furthermore, with the central support column, due to the small size of the cabinet, the width of the cabinet opening is reduced when it is necessary to inspect or disassemble internal components, affecting the installation and removal of larger components and hindering the operation of personnel, thus increasing the difficulty of repairing and disassembling internal components. Utility Model Content

[0004] Therefore, it is necessary to address the above-mentioned shortcomings by providing a column-free double-door waterproof structure and cabinet that eliminates the central column to reduce the difficulty of component maintenance and disassembly, has a small area to be waterproofed, is easy to waterproof, and has a good waterproof effect.

[0005] A column-free double-door waterproof structure includes a first door panel and a second door panel that are arranged opposite to each other and can be used to close or open a cabinet. A water guide extending along the height of the first door panel is provided on the side of the first door panel near the second door panel. A water guide groove is formed within the water guide, and a limiting plane is formed on the side of the water guide facing away from the inner space of the cabinet. An opening is provided at the top of the water guide groove, and at least one drainage hole communicating with the water guide groove is provided on the limiting plane near the bottom of the water guide groove. A waterproof strip and a limiting plate are provided on the side of the second door panel near the first door panel. The waterproof strip elastically abuts against the side of the water guide when the first and second door panels are closed, and the limiting plate is located beside the waterproof strip and covers the limiting plane.

[0006] In one embodiment, the water guide includes a first horizontal plate fixed to the first door panel near the side of the second door panel, two vertical plates disposed opposite to each other on the side of the first horizontal plate adjacent to the inner space of the cabinet and fixedly connected to the first horizontal plate, a second horizontal plate parallel to and opposite to the first horizontal plate and fixedly connected to the two vertical plates, and a bottom plate located at the bottom end of the vertical plates and fixedly connected to the first horizontal plate, the second horizontal plate, and the two vertical plates. The first horizontal plate, the second horizontal plate, and the two vertical plates together form the water guide channel. The side of the first horizontal plate facing away from the inner space of the cabinet forms the limiting plane. The drain hole is located at the bottom end of the first horizontal plate, and the bottom plate blocks the bottom end of the water guide channel.

[0007] In one embodiment, the first horizontal plate is fixed to the first door panel at a location adjacent to the inner space of the cabinet, and a step is formed between the side end face of the first door panel and the first horizontal plate. A support plate is provided on the limiting plane, extending along the height direction of the first door panel and opposite to the side end face of the first door panel. The side of the support plate facing away from the inner space of the cabinet forms a support surface. When the first door panel and the second door panel are closed, the limiting plate abuts against the support surface, and the limiting plate, the support plate, the first horizontal plate, and the side end face of the first door panel together form a guide groove.

[0008] In one embodiment, the top of the water guide is fixed with a first sealing member for sealing the top of the water guide channel. The first sealing member includes an installation part with an n-shaped cross-section and an O-shaped sealing part fixed to the top of the installation part. The inner side of the installation part is fixedly connected to the two opposite sides of the supporting upright plate, the two opposite sides of the two vertical plates, and the two opposite sides of the second horizontal plate.

[0009] In one embodiment, the pillarless double-door waterproof structure further includes a second seal located above the first seal and elastically abutting the top of the side end face of the limiting plate, wherein the lower side of the second seal elastically abuts the upper side of the first seal.

[0010] In one embodiment, a crash barrier strip is fixed on the side end face of the first door panel, located in the guide groove and extending along the height direction of the first door panel, and the side end face of the limiting plate abuts against the crash barrier strip when the first door panel and the second door panel are closed.

[0011] In one embodiment, the column-free double-door waterproof structure further includes a baffle, the upper edge of which is flush with the upper edge of the first door panel and the upper edge of the second door panel. The baffle includes a first part fixed to the side of the second door panel facing away from the inner space of the cabinet, and a second part protruding from the side end face of the second door panel and fixedly connected to the first part. When the first door panel and the second door panel are closed, the second part abuts against the side of the first door panel facing away from the inner space of the cabinet.

[0012] In one embodiment, the drain hole is a circular hole or an elliptical hole.

[0013] In one embodiment, the first door panel is provided with a first door lock, and the second door panel is provided with a second door lock that cooperates with the first door lock to lock the first door panel and the second door panel.

[0014] This utility model also discloses a cabinet, which includes the above-mentioned column-free double-door waterproof structure, as well as a main unit chassis and a power module housed in the main unit chassis. The main surface of the main unit chassis has an installation opening that communicates with the inner cavity of the main unit chassis. The first door panel and the second door panel are arranged opposite to each other at the installation opening and are pivotally connected to the main unit chassis. The main surface of the main unit chassis has a door frame seal extending along a ring path at the edge of the installation opening and elastically abutting against the first door panel and the second door panel.

[0015] The present invention relates to a column-free double-door waterproof structure and cabinet. A water-guiding component with a water-guiding groove is fixed to the edge of the first door panel, with a drainage hole at the bottom of the groove. A waterproof strip and a limiting plate are installed on the second door panel, elastically abutting against the side of the water-guiding component. The mating part of the first and second door panels is waterproofed by the waterproof strip. When water seeps into the top of the connection between the first and second door panels, the seeping water flows down the inner wall of the water-guiding groove and is discharged through the drainage hole, preventing water from entering the cabinet and improving the waterproof effect after the first and second door panels are closed. Removing the central column reduces the area requiring waterproofing while maintaining the sealing effect after the first and second door panels are closed, thus reducing the waterproofing difficulty. Furthermore, the elimination of the central column facilitates the maintenance and disassembly of components inside the cabinet, reducing the difficulty of component maintenance and disassembly.

[0027] 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.

[0028] This utility model provides a double-door waterproof structure without a central column. By eliminating the central column, it eliminates the impact on the disassembly and assembly of large components and the interference caused by the central column when the central column is present. At the same time, it reduces the area that needs to be waterproofed when the cabinet doors are closed, thereby reducing the difficulty of waterproofing. By waterproofing and water-guiding treatment at the connection point and above the connection point of the two closed doors, water entering the cabinet cavity can be significantly reduced or even eliminated, thus improving the waterproof effect of the cabinet.

[0029] For specific details, please refer to... Figure 1-10 The column-free double-door waterproof structure of this embodiment is used for installation on a server rack to close the internal cavity of the rack or open the rack. The column-free double-door waterproof structure includes a first door panel 100 and a second door panel 200 that are arranged opposite each other and can cooperate to close or open the rack. When the first door panel 100 and the second door panel 200 are close to each other and fit together (closed) to form a planar barrier, they close the internal cavity of the rack. When the first door panel 100 and the second door panel 200 are far apart, they allow the internal cavity of the rack to communicate with the external environment to open the rack. In this embodiment, both the first door panel 100 and the second door panel 200 are rectangular plate structures. The side of the first door panel 100 adjacent to the inner space of the cabinet is the inner side of the first door panel 100, and the side of the first door panel 100 facing away from the inner space of the cabinet is the outer side of the first door panel 100. Correspondingly, the side of the second door panel 200 adjacent to the inner space of the cabinet is the inner side of the second door panel 200, and the side of the second door panel 200 facing away from the inner space of the cabinet is the outer side of the second door panel 200. The side of the first door panel 100 adjacent to the second door panel 200 is the side end face of the first door panel 100, and the side of the second door panel 200 adjacent to the first door panel 100 is the side end face of the second door panel 200. A water guide 300 extending along the height of the first door panel 100 is provided on one side near the second door panel 200. A water guide groove 310 is formed inside the water guide 300, and a limiting plane 320 is formed on the side of the water guide 300 facing away from the inner space of the cabinet. The top of the water guide groove 310 has an opening, and at least one drain hole 330 communicating with the water guide groove 310 is formed on the limiting plane 320 near the bottom end of the water guide groove 310. It can also be understood that the drain hole 330 is formed on the outer bottom of the water guide groove 310. In this way, water entering the water guide groove 310 will flow downward along the inner wall of the water guide groove 310 and be discharged through the drain hole 330. Even if rainwater or other water seeps in from the top of the contact area between the first door panel 100 and the second door panel 200, this part of the water will still enter the water guide groove 310 and be discharged through the drain hole 330, so as to prevent water from entering the inner cavity of the cabinet. A waterproof strip 210 and a limiting plate 220 are provided on the side of the second door panel 200 near the first door panel 100. The waterproof strip 210 elastically abuts against the side of the water guide 300 when the first door panel 100 and the second door panel 200 are closed. The limiting plate 220 is located next to the waterproof strip 210 and covers the limiting plane 320. The waterproof strip 210 is used to provide waterproof protection for the contact surface between the first door panel 100 and the second door panel 200, while the limiting plate 220 is used to shield the waterproof strip 210 to prevent it from aging rapidly under direct sunlight, thereby extending its service life and ensuring the reliability of the waterproof structure of the double-door door without a central support column.

[0030] It should be noted that in this embodiment, the height of the waterproof strip 210 is the same as the height of the water guide 300, and the top of the waterproof strip 210 is flush with the top of the water guide 300, and the bottom of the waterproof strip 210 is flush with the bottom of the water guide 300. The height of the water guide 300 must be greater than the height of the installation opening on the cabinet to be closed by the first door panel 100 and the second door panel 200. In this way, when the first door panel 100 and the second door panel 200 are closed, the contact between the waterproof strip 210 and the side of the water guide 300 can provide waterproof protection along the entire height of the double-door waterproof structure without a central support column, achieving full-height waterproofing of the mating parts of the first door panel 100 and the second door panel 200, thus avoiding insufficient sealing caused by partial exposure of the installation opening. In addition, the top of the limiting plate 220 is higher than the top of the waterproof strip 210, and the bottom of the limiting plate 220 is lower than the bottom of the waterproof strip 210, so as to achieve complete coverage of the waterproof strip 210.

[0031] In one embodiment, the first door panel 100 includes a first vertical connecting strip 110 and a second vertical connecting strip 120 arranged parallel to each other, a first horizontal connecting strip 130 fixedly connected to the top ends of the first vertical connecting strip 110 and the second vertical connecting strip 120, and a second horizontal connecting strip 140 fixedly connected to the bottom ends of the first vertical connecting strip 110 and the second vertical connecting strip 120. The first vertical connecting strip 110, the second vertical connecting strip 120, the first horizontal connecting strip 130, and the second horizontal connecting strip 140 together form a U-shaped frame. A first panel 150 is fixed to the outer side of the U-shaped frame (the side facing away from the inner space of the cabinet), and the outer edge of the first panel 150 is flush with the outer edge of the U-shaped frame. The first vertical connecting strip 110 is adjacent to the second door panel 200. The water guide 300 is fixed to the side end face of the first door panel 100. For example, the water guide 300 is fixed to the side end face of the first panel 150, or to the side of the first vertical connecting strip 110, or to the side of the first vertical connecting strip 110 adjacent to the inner space of the cabinet.

[0032] In this embodiment, the water guide 300 includes a first horizontal plate 340 fixed on the first door panel 100 near the side of the second door panel 200, two vertical plates 350 disposed opposite to each other on the side of the first horizontal plate 340 adjacent to the inner space of the cabinet and fixedly connected to the first horizontal plate 340, a second horizontal plate 360 ​​disposed parallel to and opposite to the first horizontal plate 340 and fixedly connected to the two vertical plates 350, and a bottom plate 370 located at the bottom end of the vertical plates 350 and fixedly connected to the first horizontal plate 340, the second horizontal plate 360 ​​and the two vertical plates 350. The first horizontal plate 340, the second horizontal plate 360 ​​and the two vertical plates 350 together form a water guide channel 310. A limiting plane 320 is formed on the side of the first horizontal plate 340 facing away from the inner space of the cabinet. A drain hole 330 is located at the bottom end of the first horizontal plate 340, and the bottom plate 370 blocks the bottom end of the water guide channel 310. The water guide component 300 can be understood as a hollow columnar structure with a rectangular or square cross-section, an open top, and a closed bottom. By setting the drain hole 330 at the bottom of the water guide trough 310 and on the first horizontal plate 340, and with the drain hole 330 located on the back side of the water guide trough 310, it is ensured that the water entering the water guide trough 310 can flow downwards as much as possible and out through the drain hole 330. In addition, since the first horizontal plate 340 is located on the back side of the water guide trough 310, when the water flows out through the drain hole 330, it will have a certain speed in the horizontal direction under the action of water pressure, so that the water flows out of the water guide trough 310 along a parabolic path, preventing water from seeping into the cabinet cavity along the lower side of the first horizontal plate 340 and through the lower surface of the base plate 370. In addition, even if the water flows out of the water guide 310 at a low speed, and the water drips along the lower edge of the first horizontal plate 340, only a very small amount flows along the lower surface of the base plate 370, and this part of the water will drip off under the action of gravity. Compared with opening the drain hole 330 on the base plate 370, opening the drain hole 330 at the lower part of the first horizontal plate 340 extends the distance from the drain hole 330 to the inner space of the cabinet, reduces the possibility of water entering the inner cavity of the cabinet through the bottom of the water guide 300, and improves the waterproof effect of the double-door waterproof structure without a central support column.

[0033] Furthermore, in this embodiment, the first horizontal plate 340 is fixed to the first door panel 100 at a location adjacent to the inner space of the cabinet, and a step is formed between the side end face of the first door panel 100 and the first horizontal plate 340. Preferably, the first horizontal plate 340 is welded to the side of the first vertical connecting strip 110 adjacent to the inner space of the cabinet, and a portion of the first horizontal plate 340 extends out of the side of the first vertical connecting strip 110, thereby forming a step together with the side end face of the first panel 150 and the side of the first vertical connecting strip 110. A support plate 380 is provided on the limiting plane 320, extending along the height direction of the first door panel 100 and opposite to the side end face of the first door panel 100. The side of the support plate 380 facing away from the inner space of the cabinet forms a support surface. When the first door panel 100 and the second door panel 200 are closed, the limiting plate 220, the support plate 380, the first horizontal plate 340 and the side end face of the first door panel 100 together form a guide groove 390. In this embodiment, by setting a support plate 380, it provides limitation and support for the upper limit plate 220 of the second door panel 200, thereby limiting the relative positional relationship between the first door panel 100 and the second door panel 200 when they are closed. This ensures that the first door panel 100 and the second door panel 200 always cooperate with each other in the same position after closing. In this way, the waterproof strip 210 always elastically abuts against the side of the water guide 300 when the first door panel 100 and the second door panel 200 are closed, thereby completely sealing the gap at the mating part of the first door panel 100 and the second door panel 200 and ensuring the reliability of waterproofing. In addition, the support plate 380, the upper limit plate 220, the first horizontal plate 340, and the side end face of the first door panel 100 together form a guide groove 390. When water seeps into the top of the mating part of the first door panel 100 and the second door panel 200, since the bottom of the guide groove 390 is open and located on the outside of the cabinet, some water can also flow downward through the guide groove 390 to drain the water in time.

[0034] In this embodiment, a crash barrier 391 is fixed on the side end face of the first door panel 100, located within the guide groove 390 and extending along the height direction of the first door panel 100. The side end face of the limiting plate 220 abuts against the crash barrier 391 when the first door panel 100 and the second door panel 200 are closed. Thus, the first door panel 100 achieves a first layer of waterproofing through the elastic contact between the side of the water guide 300 and the waterproof strip 210, and a second layer of waterproofing through the contact between the crash barrier 391 and the side end face of the limiting plate 220. This double waterproofing enhances the waterproofing effect of the double-door waterproof structure without a central pillar. Preferably, the crash barrier 391 can be made of silicone, rubber, or foam material.

[0035] It should be noted that when the first door panel 100 and the second door panel 200 are closed, the top of the mating part of the first door panel 100 and the second door panel 200 actually abuts against the upper edge of the installation port to be closed on the rack. Under normal circumstances, when the external water level or rainfall is low, water can only be splashed onto the first door panel 100 and the second door panel 200 from the outer side. Therefore, with the first door panel 100 and the second door panel 200 being double waterproofed, water can be prevented from entering the rack cavity through the mating part of the first door panel 100 and the second door panel 200. When there is heavy external water or rainfall, rainwater flowing to the top of the cabinet may not be able to drain away quickly enough and may seep into the inside of the cabinet through the gap between the top of the mating part of the first door panel 100 and the second door panel 200 and the upper edge of the mounting opening. In this case, most of the water will flow downwards through the guide groove 390 and drain away by gravity. A small portion of the water will continue to seep into the inside of the cabinet along the gap and enter the water guide groove 310, and then be discharged from the drain hole 330. In other words, in this solution, the top of the mating part of the first door panel 100 and the second door panel 200 is also equipped with double waterproof protection to improve the reliability of waterproofing.

[0036] In one embodiment, a first sealing member 400 for sealing the top of the water guide 300 is fixed to the top of the water guide channel 310. The first sealing member 400 includes an mounting portion 410 with an n-shaped cross-section and an O-ring sealing portion 420 fixed to the top of the mounting portion 410. The inner side of the mounting portion 410 is fixedly connected to two opposite sides of the supporting upright plate 380, two opposite sides of the two vertical plates 350, and two opposite sides of the second horizontal plate 360. Preferably, the mounting portion 410 and the O-ring sealing portion 420 are integrally formed and both are made of foam material. The inner surface of the mounting portion 410 is bonded and fixed to the two opposite sides of the supporting upright plate 380, the two opposite sides of the two vertical plates 350, and the two opposite sides of the second horizontal plate 360 ​​to prevent it from falling off. When the first door panel 100 is fitted with the edge of the rack mounting opening (i.e., the first door panel 100 is closed), the top of the O-ring seal 420 elastically abuts against the upper edge of the mounting opening to seal the gap between the top of the water guide 300 and the upper edge of the rack mounting opening, preventing rainwater from entering the rack cavity through this gap, and trapping the rainwater in the water guide trough 310 and draining it out. Furthermore, the pillarless double-door waterproof structure also includes a second seal 500 located above the first seal 400 and elastically abutting against the top of the side face of the limiting plate 220. The lower side of the second seal 500 elastically abuts against the upper side of the first seal 400. The second seal 500 is also made of foam material. Specifically, the top of the first horizontal plate 340 extends upward to form a mounting plate 341. The width of the mounting plate 341 is smaller than the width of the first horizontal plate 340, and the mounting plate 341 abuts against the side end face of the first door panel 100. The second sealing member 500 includes an elastic fixing part 510 pasted on the mounting plate 341 on the side facing away from the inner space of the cabinet, and an O-ring sealing cylinder 520 fixedly connected to the elastic fixing part 510 on the side facing away from the inner space of the cabinet. In addition, the end of the first sealing member 400 protrudes from the support surface of the supporting upright plate 380. The position of the second sealing member 500 on the mounting plate 341 needs to meet the following requirement: when the first door panel 100 and the second door panel 200 are closed, the top of the inner side of the limiting plate 220 on the second door panel 200 elastically abuts against the O-ring sealing cylinder 520 and the end of the first sealing member 400 to seal the top of the mating part of the first door panel 100 and the second door panel 200, thereby reducing the amount of water entering the guide groove 390 and the water guide groove 310.

[0037] In one embodiment, the drain hole 330 is a circular hole or an elliptical hole. Further, in this embodiment, two drain holes 330 are vertically spaced at the lower part of the first horizontal plate 340. One drain hole 330 is circular, and the drain hole 330 below it is elliptical, extending horizontally. This increases the horizontal outlet width of the lower drain hole 330, allowing for rapid drainage of water from the water guide trough 310. Of course, in actual production, the number of drain holes 330 on the first horizontal plate 340 can be increased as needed, which will not be elaborated here.

[0038] The column-free double-door waterproof structure also includes a baffle 600. The upper edge of the baffle 600 is flush with the upper edges of the first door panel 100 and the second door panel 200. The baffle 600 includes a first part fixed to the side of the second door panel 200 facing away from the inner space of the cabinet, and a second part protruding from the side end face of the second door panel 200 and fixedly connected to the first part. When the first door panel 100 and the second door panel 200 are closed, the second part abuts against the side of the first door panel 100 facing away from the inner space of the cabinet. In this embodiment, the first part of the baffle 600 is integrally formed with the second door panel 200, or the first part of the baffle 600 is welded or screwed to the outer side of the second door panel 200. By setting up a baffle 600, when the first door panel 100 and the second door panel 200 are closed, the baffle 600 can cover the top of the mating part of the first door panel 100 and the second door panel 200, which can reduce the impact of rainwater on the top of the door panel during strong winds and rainstorms, and help ensure waterproofing.

[0039] In addition, the first door panel 100 is provided with a first door lock 101, and the second door panel 200 is provided with a second door lock 201 that cooperates with the first door lock 101 to lock the first door panel 100 and the second door panel 200 together. The first door lock 101 and the second door lock 201 can be any type of door panel lock available on the market, and their specific structures will not be described here. By setting the first door lock 101 and the second door lock 201, on the one hand, the stability of the structure after the first door panel 100 and the second door panel 200 are closed is achieved, preventing the cabinet from opening on its own. On the other hand, the first door lock 101 and the second door lock 201 limit the first door panel 100 and the second door panel 200, so that after the first door panel 100 and the second door panel 200 are closed, the waterproof strip 210 abuts against the side edge of the water guide 300, and at the same time, the side end face of the limiting plate 220 elastically abuts against the anti-collision strip 391, so as to ensure the sealing effect of the double-door waterproof structure without a central column.

[0040] In this embodiment, the shape of the second door panel 200 is the same as that of the first door panel. Specifically, the second door panel 200 includes a third vertical connecting strip 202 and a fourth vertical connecting strip 203 arranged parallel to each other, a third horizontal connecting strip 204 fixedly connected to the top of the third vertical connecting strip 202 and the fourth vertical connecting strip 203, and a fourth horizontal connecting strip 205 fixedly connected to the bottom of the third vertical connecting strip 202 and the fourth vertical connecting strip 203. The third vertical connecting strip 202, the fourth vertical connecting strip 203, the third horizontal connecting strip 204, and the fourth horizontal connecting strip 205 together form a U-shaped frame. A second panel 206 is fixed on the outer side of the U-shaped frame (the side facing away from the inner space of the cabinet). One edge of the second panel 206 protrudes from the third vertical connecting strip 202 to form a limiting plate. The third vertical connecting strip 202 is adjacent to the first door panel, and a waterproof strip 210 is fixed on the side of the third vertical connecting strip 202 adjacent to the inner cavity of the cabinet.

[0041] Please combine Figure 1-10 This utility model also discloses a cabinet, which includes the aforementioned column-free double-door waterproof structure. The column-free double-door waterproof structure is exactly the same as the column-free double-door waterproof structure in Embodiment 1. Its structure can be found in the description of the column-free double-door waterproof structure in Embodiment 1, and will not be repeated here. The cabinet also includes a main unit chassis 700 and a power module housed within the main unit chassis 700. The main surface of the main unit chassis 700 has a mounting opening 710 that communicates with the inner cavity of the main unit chassis 700. The first door panel 100 and the second door panel 200 are arranged opposite to each other at the mounting opening 710 and are pivotally connected to the main unit chassis 700 respectively. The main surface of the main unit chassis 700 has a door frame seal 720 extending along a circular path at the edge of the mounting opening 710 and elastically abutting against the first door panel 100 and the second door panel 200. Thus, by abutting the inner edges of the first door panel 100 and the second door panel 200 against the door frame seal 720, waterproofing can be achieved at the mating parts of the first door panel 100 and the main unit chassis 700, as well as at the mating parts of the second door panel 200 and the main unit chassis 700. Through the abutting of the waterproof strip 210 against the side edge of the water guide 300, and the placement of the water guide 300, waterproofing is achieved at the mating parts of the first door panel 100 and the second door panel 200, while also providing waterproofing protection at the top of the mating parts. This allows water seeping into the top of the mating parts of the first door panel 100 and the second door panel 200 to be promptly drained away, improving the reliability of the cabinet's waterproofing. In this embodiment, the door frame seal 720 is a sheet-shaped rectangular ring structure cut from sealing foam, which is glued to the edge of the mounting opening 710.

[0042] Multiple first anti-collision blocks 102 are fixedly attached to the back of the first door panel 100 from top to bottom at intervals. These first anti-collision blocks 102 are connected together by reinforcing ribs to prevent displacement. The first anti-collision blocks 102 can be made of elastic plastic blocks or rollers, and can have identical or different structures. Similarly, multiple second anti-collision blocks 207 are fixedly attached to the back of the second door panel 200 from top to bottom at intervals. These second anti-collision blocks 207 are connected together by reinforcing ribs to prevent displacement. The second anti-collision blocks 207 can also be made of elastic plastic blocks or rollers, and can have identical or different structures. By providing the first anti-collision blocks 102 and the second anti-collision blocks 207, impacts on the electrical components inside the cabinet can be prevented when the first door panel 100 and the second door panel 200 are closed, thus protecting the electrical components.

[0043] In actual use, the first door panel 100 and / or the second door panel 200 are also equipped with control buttons and corresponding display devices connected to the power module inside the cabinet. For example, a power display device electrically connected to the power module is provided on the first door panel 100 and / or the second door panel 200, or a temperature sensor is provided inside the cabinet, and a temperature display device electrically connected to the temperature sensor is provided on the first door panel 100 and / or the second door panel 200, or a touch screen or control panel electrically connected to the power module is provided on the first door panel 100 and / or the second door panel 200, so that users can understand the working status of the power module inside the cabinet and perform corresponding operations.

[0044] The present invention relates to a column-free double-door waterproof structure and cabinet. A water-guiding component 300 with a water-guiding groove 310 is fixed to the edge of the first door panel 100, and a drainage hole 330 is provided at the bottom end of the water-guiding groove 310. A waterproof strip 210 and a limiting plate 220 are provided on the second door panel 200, elastically abutting against the side of the water-guiding component 300. The mating part of the first door panel 100 and the second door panel 200 is waterproofed by the waterproof strip 210. When water seeps into the top of the connection between the first door panel 100 and the second door panel 200, the water seeps into the cabinet. Water will flow down the inner wall of the water guide channel 310 and be discharged through the drain hole 330, which can prevent water from entering the chassis and improve the waterproof effect after the first door panel 100 and the second door panel 200 are closed. After removing the central column, while ensuring the sealing effect after the first door panel 100 and the second door panel 200 are closed, the number of parts that need to be waterproofed is reduced, the area to be waterproofed is reduced, and the difficulty of waterproofing is reduced. At the same time, the elimination of the central column is conducive to the maintenance and disassembly of the components inside the cabinet, reducing the difficulty of component maintenance and disassembly.
