Description

Technical Field

[0001] The present application relates to the technical field of charging equipment protection, and in particular to a sheet metal box with a waterproof structure. Background Art

[0002] With the continued promotion and popularization of electric vehicles, the construction of charging infrastructure has become increasingly important. As a key component of the charging network, the performance of outdoor charging stations is directly related to the user experience of electric vehicle users and the long-term stable operation of the equipment. Reliable and durable outdoor charging stations can provide users with convenient and efficient charging services, enhance user confidence in electric vehicles, and promote the further development of the electric vehicle industry. Furthermore, good charging facilities can help improve the environmental benefits of the entire transportation system and promote the optimization of the energy structure.

[0003] In practical applications, a common approach to dissipating heat within charging piles is to create cooling holes in the sidewalls. This approach leverages natural convection to draw cool air into the charging pile, removing heat before discharging it, thereby lowering the internal temperature.

[0004] However, these existing heat dissipation methods have certain drawbacks. When the water level around the charging pile rises due to poor drainage, rainwater may enter the charging pile through the heat dissipation holes, seriously affecting the charging pile's waterproofing. This may cause electrical failures and threaten the safe and stable operation of the equipment. Summary of the Invention

[0005] In order to reduce the amount of rainwater that enters the charging pile through the heat dissipation holes, the present application provides a sheet metal box with a waterproof structure.

[0006] The sheet metal box with a waterproof structure provided in this application adopts the following technical solutions:

[0007] A sheet metal box with a waterproof structure, comprising a box body and a waterproof structure, wherein the charging pile is provided with a ventilation cavity, the bottom of which is in communication with the outside world; a first heat dissipation portion and a second heat dissipation portion are respectively provided on opposite sides of the ventilation cavity, the first heat dissipation portion being used to communicate with the outside world, and the second heat dissipation portion being used to communicate with the interior of the charging pile;

[0008] The waterproof structure includes a cover plate and a floating component. The cover plate is slidably installed in the air-permeable cavity and is used to cover the surface of the second heat dissipation part. The floating component includes a float ball, and the float ball is used to drive the cover plate to move upward.

[0009] By adopting the above technical solution, the first heat dissipation part and the second heat dissipation part are arranged opposite to each other with a distance between them, which can reduce the situation where rainwater directly enters the interior of the charging pile through the first heat dissipation part.

[0010] When the water level rises due to poor external drainage performance, the air permeable cavity connected to the bottom allows water to enter. The float installed on the bottom wall of the cover plate drives the cover plate to move as the water level rises, and then drives the cover plate to cover the surface of the second heat dissipation part, which can effectively reduce the flow of rainwater into the box through the second heat dissipation part, thereby improving the waterproof performance of the charging column. At the same time, there is no need to manually observe the charging pile environment to manually control the opening and closing of the second heat dissipation part.

[0011] Optionally, two opposite sides of the air-permeable cavity are provided with sliding grooves, and the two ends of the cover plate are respectively slidably mounted on the two sliding grooves; the end of the sliding groove away from the first heat dissipation part is arranged to be tilted upward.

[0012] By adopting the above-mentioned technical solution, the sliding grooves connected on both sides of the air-permeable cavity can enable the cover plate to slide stably in the movable cavity, ensuring its movement trajectory; the sliding groove is tilted upward at one end away from the first heat dissipation part, which can allow the cover plate to better fit the box body when the accumulated water drives the cover plate to move up, thereby more effectively covering the second heat dissipation part, enhancing the waterproof effect, and reducing rainwater from flowing into the box body through the second heat dissipation part.

[0013] Optionally, a rubber layer is provided on a side of the cover plate close to the second heat dissipation portion.

[0014] By adopting the above technical solution, the rubber layer provided on the side of the cover plate close to the box body can enhance the sealing between the cover plate and the box body, and further reduce the flow of rainwater into the charging pile from the connection between the cover plate and the box body.

[0015] Optionally, a movable rod is provided on one side of the float, and a rotating groove is provided on the side of the cover plate away from the second heat dissipation part, and the movable rod is connected to the inner wall of the rotating groove through a rotating shaft; an extrusion groove is provided on the inner wall of the rotating groove, and an extrusion component is provided in the extrusion groove, and a sealing ring groove for the extrusion component to be inserted is provided on the inner wall of the air-permeable cavity; when the rotating shaft rotates to squeeze the extrusion component, the extrusion component is inserted into the sealing ring groove.

[0016] By adopting the above-mentioned technical solution, during the process of rising accumulated water, the float drives the cover plate to move upward and cover the surface of the second heat dissipation part; at this time, the accumulated water continues to rise, thereby enabling the float to rotate and squeeze the extrusion component, so that the extrusion component is inserted into the sealing ring groove, thereby increasing the waterproof sealing performance of the second heat dissipation part.

[0017] Optionally, the extrusion component includes a first airbag and a second airbag, and the first airbag is installed in the extrusion groove; a mounting groove is provided on the side of the cover plate close to the second heat dissipation part, and the second airbag is installed in the mounting groove; the second airbag is connected to the first airbag, and the second airbag is used to be plugged into and matched with the sealing ring groove.

[0018] By adopting the above-mentioned technical solution, the rotating shaft on one side of the float is rotatably connected to the bottom of the cover plate. When water accumulates, the rotating shaft of the float rotates to squeeze the first airbag in the active cavity. The gas in the first airbag enters the second airbag through the connecting channel. The second airbag expands and is inserted into the sealing ring groove on the inner wall of the air permeable cavity, thereby enhancing the waterproof sealing performance of the second heat dissipation part.

[0019] Optionally, the first airbag is provided with a spring, and the elastic force of the spring is used to drive the first airbag to restore to an expanded state.

[0020] By adopting the above technical solution, the first airbag is provided with a spring, and after the accumulated water is drained, the spring force can be used to drive the first airbag to restore the expanded state, so that the second airbag can be reset so that the waterproof structure can be used again.

[0021] Optionally, an extrusion plate is attached to the first airbag, and the movable rod is used to abut against the extrusion plate.

[0022] By adopting the above-mentioned technical solution, the movable rod can contact the extrusion plate when rotating to push the extrusion plate, thereby squeezing the first airbag; and the extrusion plate and the hinged movable rod can increase the force-bearing area of ​​the first airbag and increase the compression volume of the first airbag during deformation, thereby increasing the volume of gas entering the second airbag from the first airbag, thereby improving the expansion capacity of the second airbag.

[0023] Optionally, a connecting rod assembly is provided between the cover plate and the inner wall of the air permeable cavity, and the connecting rod assembly includes a first rod and a second rod hinged to the first rod, and the end of the first rod away from the second rod is rotatably connected to the inner wall of the air permeable cavity; the end of the second rod away from the first rod is rotatably connected to the cover plate, and the float is installed at the hinge between the first rod and the second rod.

[0024] By adopting the above-mentioned technical solution, when the water level rises, the float moves upward, driving the hinge of the first rod and the second rod to move upward, so that the first rod and the second rod are away from each other at one end of their own hinge; because the first rod is rotatably connected to the inner wall of the air permeable cavity, and the second rod is rotatably connected to the cover plate, the cover plate can be driven to slide upward and cover the surface of the second heat dissipation part; after the cover plate covers the second heat dissipation part, when the water level continues to rise, the float will make the cover plate press against the outer wall of the box, thereby enhancing the sealing effect and reducing the situation where rainwater flows into the interior of the box through the gap between the cover plate and the inner wall of the air permeable cavity.

[0025] Optionally, the box body includes a cabinet body and a mounting plate, and the air permeable cavity is opened in the cabinet body; the mounting plate is detachably connected to the inner wall of the air permeable cavity by a first bolt, and the sliding groove is opened in the mounting plate.

[0026] By adopting the above technical solution, the assembly plate can realize detachable connection between the first rod and the mounting plate through the first bolt, so as to facilitate assembly and maintenance.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. When the water level rises due to poor external drainage, the movable chamber connected to the bottom allows water to enter. The float installed on the bottom wall of the cover plate moves with the rising water level, driving the cover plate to cover the surface of the second heat dissipation part. This can effectively reduce the flow of rainwater into the box through the second heat dissipation part, improving the waterproof performance of the charging column. At the same time, there is no need to manually observe the charging pile environment to manually control the opening and closing of the second heat dissipation part.

[0029] 2. By setting up an extrusion component, when the accumulated water rises and the float rotates, the rotating shaft rotates and squeezes the first airbag in the active cavity. The gas in the first airbag enters the second airbag through the connecting channel. The second airbag expands and inserts into the sealing ring groove on the inner wall of the air permeable cavity, thereby enhancing the waterproof sealing performance of the second heat dissipation part.

[0040] The following is combined with Figures 1-9 This application is described in further detail. Embodiment 1:

[0041] The embodiment of the present application discloses a sheet metal box with a waterproof structure.

[0042] Reference Figure 1 and Figure 2 A sheet metal box with a waterproof structure 2 includes a box 1 and a waterproof structure 2. The main body of the charging pile includes a cabinet 11, a first cabinet door 12, a mounting plate 13 and a second cabinet door 14. The cabinet 11 has an equipment compartment 15. The first cabinet door 12 is rotatably installed on the cabinet 11 for opening and closing the equipment compartment 15. In this embodiment, the side edges of the first cabinet door 12 are provided with foam glue. The foam glue is elastic. When the first cabinet door 12 is in the closed state, the foam glue is squeezed so that it is pressed against the inner wall of the cabinet 11, thereby reducing the situation where rainwater enters the interior of the equipment compartment 15 from the first cabinet door 12.

[0043] Reference Figure 1 and Figure 2 , air-permeable cavities 16 are provided on opposite sides of the cabinet body 11, and the bottom wall of the air-permeable cavity 16 is communicated with the outside world; two groups of second cabinet doors 14 are provided, and the two groups of second cabinet doors 14 are hinged on opposite sides of the air-permeable cavity 16, respectively, for covering the surface of the air-permeable cavity 16; in this embodiment, the second cabinet door 14 is provided with a plurality of first heat dissipation parts 17 at intervals along the height direction, and these first heat dissipation parts can be in the form of heat dissipation holes or heat dissipation grilles. In this embodiment, the first heat dissipation parts 17 are configured as heat dissipation grilles.

[0044] Reference Figure 2, a plurality of second heat dissipation parts 18 are arranged at intervals along the height direction on the inner wall of the ventilation cavity 16, and the second heat dissipation parts 18 are arranged opposite to the first heat dissipation parts 17 of the two second cabinet doors 14; these second heat dissipation parts 18 can be in the form of heat dissipation holes or heat dissipation grilles. In this embodiment, the second heat dissipation parts 18 adopt a plurality of heat dissipation holes opened in the ventilation cavity, and their shapes can be circular, square, etc. The second heat dissipation parts 18 are connected to the equipment compartment 15 and are used to dissipate the heat generated by the equipment in the equipment compartment 15 when it is working.

[0045] Reference Figure 3 The waterproof structure 2 is provided in multiple groups, each of which covers a respective second heat dissipation portion 18. The waterproof structure 2 includes a cover plate 3 and a floating assembly 4. The cover plate 3 is slidably mounted within the vent cavity 16. In this embodiment, the mounting plate 13 is mounted to the inner wall of the vent cavity 16 via a first bolt 131. The mounting plate 13 defines two slide grooves 132, with the ends of the cover plate 3 slidingly connected to the two slide grooves 132, which guide the sliding movement of the cover plate 3. The cover plates 3 are connected to the mounting plate 13, allowing all cover plates 3 and the mounting plate 13 to be removed for easy inspection and maintenance.

[0046] Also refer to Figure 4 In order to better allow the cover plate 3 to cover the second heat dissipation portion 18, the end of the slide groove 132 away from the second cabinet door 14 is tilted upward, so that the cover plate 3 can more accurately cover the second heat dissipation portion 18 when it moves upward.

[0047] Reference Figure 3 The cover plate 3 may be provided with a rubber layer 31 on the side closest to the cabinet 11. The rubber layer 31 is elastic and seals well. When the cover plate 3 covers the second heat sink 18, the rubber layer 31 can better fit around the second heat sink 18, enhancing the waterproof effect. The rubber layer 31 is generally made of a material such as nitrile rubber and is fixed to the cover plate 3 by adhesive bonding or other methods.

[0048] Reference Figure 3 The float assembly 4 is used to propel the cover plate 3 over the surface of the second heat sink 18. It includes multiple floats, all mounted on the bottom wall of the cover plate 3. When water accumulates, it enters the vent cavity 16. The floats, acting as a buoyant force, move upward, driving the cover plate 3 upward along the chute 132, ultimately covering the surface of the second heat sink 18 and preventing rainwater from entering. The floats are typically made of a lightweight, waterproof material such as plastic and are secured to the bottom wall of the cover plate 3 by welding or bolting.

[0049] The implementation principle of Example 1 of the present application is:

[0050] The charging column of this embodiment is provided with a waterproof structure 2. Under normal circumstances, air can circulate through the first heat dissipation part 17 and the second heat dissipation part 18 to meet the heat dissipation requirements of the charging pile.

[0051] When water accumulates, the float installed on the bottom wall of the cover 3 drives the cover 3 to move as the water level rises, thereby driving the cover 3 to cover the surface of the second heat dissipation part 18, which can effectively reduce the flow of rainwater into the interior of the box 1 through the second heat dissipation part 18, thereby improving the waterproof performance of the charging column; at the same time, there is no need to manually observe the charging pile environment to manually control the opening and closing of the second heat dissipation part 18. Example 2:

[0052] The embodiment of the present application discloses a sheet metal box having a waterproof structure 2.

[0053] Reference Figure 5 and Figure 6 The difference between Example 2 of the present application and Example 1 is that a movable rod 41 is provided on one side of the float, a rotation groove 32 is opened on the side of the cover plate 3 away from the cabinet 11, a rotation shaft 42 is installed in the rotation groove 32, and the movable rods 41 of all floats are rotatably connected to the rotation shaft 42.

[0054] Reference Figure 6 and Figure 7 An extrusion groove 33 is provided on the inner wall of the rotating groove 32, and an extrusion component 5 is installed in the extrusion groove 33. The extrusion component 5 includes a first airbag 51, a second airbag 52 and a spring 53. The first airbag 51 is installed in the extrusion groove 33, and the movable rod 41 is rotated to be extruded with the first airbag 51; the spring 53 is installed in the first airbag 51, and the elastic force of the spring 53 can keep the first airbag 51 in an expanded state.

[0055] Reference Figure 7 In this embodiment, an extrusion plate 54 is attached to the side of the first airbag 51 close to the movable rod 41. When the movable rod 41 rotates, it can contact the extrusion plate 54 to squeeze the first airbag 51; the setting of the extrusion plate 54 can increase the compression volume of the first airbag 51.

[0056] A mounting groove 34 is provided on one side of the cover plate 3 close to the box body 1, and the head and tail ends of the mounting groove 34 are connected, that is, the shape of the mounting groove 34 is the same as that of the cover plate 3; the second airbag 52 is installed in the mounting groove 34, and the second airbag 52 is connected to the first airbag 51; when the second airbag 52 receives the gas in the first airbag 51 and expands, the air permeable cavity 16 is provided with a sealing ring groove 19 for the second airbag 52 to be inserted.

[0057] The implementation principle of Example 2 of this application is:

[0058] As the accumulated water rises, the first airbag 51 abuts against the side wall of the movable rod 41, which can prevent the float from rotating freely, so that the float drives the cover plate 3 to move upward and cover the surface of the second heat dissipation portion 18; then, as the accumulated water continues to rise, the float moves upward with the accumulated water, and the movable rod 41 overcomes the elastic force of the first airbag 51, rotates and squeezes the first airbag 51, and the gas in the first airbag 51 is pressed into the second airbag 52, causing the second airbag 52 to expand and insert into the sealing ring groove 19, further enhancing the waterproof sealing performance.

[0059] When the accumulated water recedes, the float drops, and the rotating shaft 42 no longer squeezes the first airbag 51. Under the action of the spring 53, the first airbag 51 returns to its original state, and the gas in the second airbag 52 flows back to the first airbag 51, and the second airbag 52 shrinks; then when the accumulated water continues to recede, the cover plate and the float move downward, and the cover plate 3 cancels the coverage of the second heat dissipation part 18. Example 3:

[0060] The embodiment of the present application discloses a sheet metal box having a waterproof structure 2.

[0061] Reference Figure 8 and Figure 9 The difference between Example 3 of the present application and Example 1 is that: the first heat dissipation portion 17 is set as a heat dissipation hole, and an inclined plate 181 is provided on the outside of the second cabinet door 14, and the inclined plate 181 can reduce the situation where rainwater directly enters the air permeable cavity 16 through the first heat dissipation portion 17; a plurality of connecting rod assemblies 6 are provided in the air permeable cavity 16, and a plurality of assembly plates 63 are provided at one end of the cover plate 3 away from the second heat dissipation portion 18, and both ends of the assembly plate 63 are connected to the mounting plate 13; the connecting rod assembly 6 is used to connect the assembly plate 63 and the cover plate 3.

[0062] Reference Figure 9 The connecting rod assembly 6 includes a first rod 61 and a second rod 62. One end of the first rod 61 is rotatably connected to the assembly plate 63, and one end of the second rod 62 is rotatably connected to the cover plate 3; the end of the first rod 61 away from the assembly plate 63 is rotatably connected to the end of the second rod 62 away from the cover plate 3; the float is installed at the hinge of the first rod 61 and the second rod 62.

[0063] The implementation principle of Example 3 of this application is:

[0064] When the water level rises, the float moves upward, driving the hinge of the first rod 61 and the second rod 62 to move upward, so that the first rod 61 and the second rod 62 are separated from each other at one end of the hinge. Since the first rod 61 is rotatably connected to the assembly plate 63 and the second rod 62 is rotatably connected to the cover plate 3, the cover plate 3 can be driven to move toward one side of the second heat dissipation portion 18 and cover the surface of the second heat dissipation portion 18. After the cover plate 3 covers the second heat dissipation portion 18, when the water level continues to rise, the float will make the cover plate 3 press against the inner wall of the air permeable cavity, thereby enhancing the sealing effect.

[0065] The above are preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
