Description

Technical Field

[0001] The present invention relates to the technical field of energy storage power supplies, and in particular to a waterproof structure and an energy storage power supply based on the waterproof structure. Background Art

[0002] The energy storage power supply integrates high-performance inverter technology to realize the conversion of DC power of lithium iron phosphate battery pack into pure sine wave AC power. The output voltage is compatible with 120V and 240V (supports simultaneous split-phase output), ensuring power supply quality and flexibility. Built-in 240V AC EV fast charging function meets the emergency power replenishment needs of electric vehicles. When the battery is exhausted or reaches the end of its use, it can be efficiently charged by connecting to the mains power grid or photovoltaic panels. In an environment without mains power access, the energy storage system can stably supply household appliances that meet power requirements such as refrigerators, electric hammers, induction cookers, rice cookers, electric fans, washing machines, televisions and air conditioners to ensure emergency or outdoor life electricity.

[0003] In terms of design, existing energy storage power supplies integrate major accessories such as metal casing, photovoltaic inverter, touch screen, lithium iron phosphate battery, etc. In order to improve the convenience of maintenance, the side of the metal casing is usually designed with an openable opening, equipped with a removable baffle with good sealing. Given that mobile energy storage equipment is often used in complex and changeable outdoor environments, the removable baffle is usually designed as a waterproof material to improve the waterproof performance of the energy storage power supply. However, the current design does not fully consider the water seepage problem that may occur at the connection between the opening and the baffle.

[0004] In view of the above situation, the present invention focuses on improving the waterproof performance, improves the metal shell and the detachable baffle connection part, and designs a waterproof structure and an energy storage power supply based on the waterproof structure. Summary of the invention

[0005] In view of the problems existing in the above-mentioned prior art, the present invention provides a waterproof structure and an energy storage power supply based on the waterproof structure. By improving the opening part of the metal shell and combining it with the waterproof shell, an effective water storage and water conduction space is formed to ensure that moisture is not easy to penetrate into the interior of the metal shell, thereby avoiding water seepage at the connection between the opening and the baffle.

[0006] In order to achieve the above object, the waterproof structure adopted by the present invention includes:

[0007] A metal shell, wherein one side of the metal shell has an opening, an outer edge extends outward from the opening, the outer edge has a straight portion, an inclined portion connected to both sides of the straight portion and inclined downward, and a vertical portion extending vertically downward along the inclined end of the inclined portion, the extended end of the outer edge is folded to form a supporting portion, and the straight portion and the supporting portion form a water storage space;

[0008] A waterproof shell is installed on the outer edge and covers and closes the upper surface of the water storage channel. The waterproof shell and the outer edge are fixed by at least two bolts along the straight line direction of the support part.

[0009] The above structure forms an effective water storage space by improving the opening part of the metal shell and combining it with a waterproof shell. The water storage space can collect and temporarily store moisture flowing through the shell, ensuring that moisture is not easy to penetrate into the metal shell from the connection between the opening and the baffle.

[0010] As a further optimization of the above scheme, the cross-section of the straight portion is inclined from both sides of the middle of the straight portion, the inclined portions are arranged at the inclined ends on both sides of the straight portion, and a water outlet for water outflow is provided below the vertical portion. The straight portion, the inclined portion, the vertical portion, the supporting portion and the waterproof shell form a water guide space. The inclined design of the cross-section of the straight portion is beneficial to the flow and discharge of water, and the water outlet ensures that the water can be discharged smoothly to avoid water accumulation.

[0011] As a further optimization of the above solution, the inner surface of the waterproof shell is connected to at least one crossbeam, and the crossbeam bridges the frames of the metal shells on the left and right sides of the opening in the straight direction of the straight part. By adding the crossbeam structure, the connection strength between the waterproof shell and the metal shell is improved, thereby preventing structural deformation or damage caused by external force.

[0012] As a further optimization of the above scheme, considering that the fastening work of the existing mobile storage power supply is only fastened by screws in a single direction, due to movement in the field environment, external forces different from the fastening direction may be generated in the horizontal and longitudinal directions, and there is a situation where the threads loosen after being used for a period of time. The present invention improves the internal structure of the above-mentioned water-conducting space, and a plurality of first support frames are provided on the water-conducting space, and two adjacent first support frames are formed with plug-in grooves. The length direction of the first support frame is parallel to the straight direction of the above-mentioned straight segment, and at least one plug-in board is plugged into the plug-in groove, and the plug-in board is arranged parallel to the above-mentioned support part. At least one screw passes through the support plate and the plug-in board and locks the support plate and the plug-in board. An accommodating channel is formed between two adjacent support parts perpendicular to the length direction of the first support frame, and a second support frame with a length direction perpendicular to the length direction of the first support frame is placed in the accommodating channel. A connecting slide groove is provided between two adjacent second support frames, and the cross-section of the connecting slide groove forms a rectangular shape, and the plug-in board has a sliding part that cooperates with the connecting slide groove structure.

[0013] Based on the design of the first support frame and the second support frame, the above structure strengthens the support structure in the horizontal and vertical dimensions of the water-conducting space. Through the plug-in board, a stable connection is achieved between the first support frame, the second support frame, the waterproof shell and the support part, thereby significantly improving the structural rigidity and stability of the connection between the opening and the waterproof shell. In addition, the above design also cleverly uses the connecting slide and the plug-in slot, so that the water source that penetrates from the junction of the waterproof shell and the opening must flow through the above connecting slide and the plug-in slot, and can only flow to the bottom of the water-conducting space after a series of tortuous paths, effectively extending the water flow path, and also reducing the risk of external water sources penetrating into the metal shell through the junction of the opening and the baffle, achieving a double protection effect. At the same time, the design of the connecting slide facilitates the sliding of the plug-in board, and combined with the plug-in slot, it plays a role in accurately positioning and fixing the plug-in board.

[0014] As a further optimization of the above-mentioned scheme, dovetail grooves are formed on both sides of the sliding part, and a dovetail slider that cooperates with the dovetail groove is installed on the second support frame. The design of the dovetail structure provides a larger contact area and a more stable sliding support, ensuring the smoothness and accuracy of the movement of the plug board.

[0015] As a possible improvement to the above scheme, the top surface of the second support frame and the top surface of the water guiding space have a first accommodating space, the top surface of the connecting chute is provided with a strip groove for supplying water from the first accommodating space into the inside of the connecting chute, and a second accommodating space is formed between two adjacent plug-in plates, a rotating shaft is provided on the top of one of the plug-in plates in the second accommodating space, the rotating shaft rotates by being connected to the two sides of the connecting chute, a sealing gasket is wound or unfolded on the rotating shaft and the sealing gasket seals the above-mentioned strip groove in the unfolded state, a first gear is provided on the opposite side of the rotating shaft, a second gear is meshed on the first gear, a rope is wound around the above-mentioned second gear and one end of the rope is connected to the connecting plate, the connecting plate is hinged on the plug-in plate, a spring is provided between the end of the connecting plate facing away from the connecting plate and the plug-in plate, the other end of the rope is connected to the fixed end of the above-mentioned sealing gasket, a limiting block is fixed on the plug-in plate arranged opposite to the second accommodating space and the rotating shaft, a rectangular through hole is opened on the limiting block, part of the rack passes through the rectangular through hole, and the tooth surface of the rack contacts the first gear.

[0016] The above structure, support frame, waterproof shell and other components together form a complete waterproof structure. The waterproof structure has dual use states: in the drainage state, when the water accumulation is shallow, the water will flow along the designed tortuous path to achieve effective drainage function;

[0017] When the water level rises to a certain level, the waterproof structure will quickly trigger the deployment of the sealing gasket through the linkage of mechanical components such as rotating shafts, gears and ropes, thereby closing the entrance of the tortuous flow path. The above transformation puts the waterproof system into a closed state, preventing large amounts of water from pouring into the tortuous path, ensuring reliable protection in different environments.

[0018] The energy storage power supply based on the waterproof structure applies the waterproof structure as described in any of the technical solutions mentioned above.

[0019] The waterproof structure of the present invention and the energy storage power supply based on the waterproof structure have the following beneficial effects:

[0020] 1. The waterproof structure of the present invention and the energy storage power supply based on the waterproof structure form an effective water storage space by improving the opening part of the metal shell and combining it with the waterproof shell. The water storage space can collect and temporarily store moisture flowing through the shell, ensuring that moisture is not easy to penetrate into the interior of the metal shell from the connection between the opening and the baffle.

[0021] 2. The waterproof structure of the present invention and the energy storage power supply based on the waterproof structure, based on the design of the first support frame and the second support frame, the above structure strengthens the support structure in the horizontal and vertical dimensions of the water-conducting space. Through the plug-in board, a stable connection between the first support frame, the second support frame, the waterproof shell and the support portion is achieved, thereby significantly improving the structural rigidity and stability of the connection between the opening and the waterproof shell. In addition, the above design also cleverly uses the connecting slide and the plug-in slot, so that the water source that penetrates from the junction of the waterproof shell and the opening must flow through the above connecting slide and the plug-in slot, and can only flow to the bottom of the water-conducting space after a series of tortuous paths, effectively extending the water flow path, and also reducing the risk of external water sources penetrating into the metal shell through the junction of the opening and the baffle, achieving a double protection effect. At the same time, the design of the connecting slide facilitates the sliding of the plug-in board, and combined with the plug-in slot, it plays a role in accurately positioning and fixing the plug-in board.

[0022] 3. The waterproof structure of the present invention and the energy storage power source based on the waterproof structure, together with the support frame, waterproof housing and other components, form a complete waterproof structure. The waterproof structure has dual use states: in the drainage state, when the water accumulation is shallow, the water will flow along the designed tortuous path to achieve effective drainage function; when the water level rises to a certain level, the waterproof structure will quickly trigger the deployment of the sealing gasket through the linkage of mechanical parts such as rotating shafts, gears and ropes, thereby closing the entrance of the tortuous flow path. The above transformation puts the waterproof system into a closed state, preventing a large amount of water from flowing into the tortuous path, ensuring reliable protection in different environments.

The terms used in the specification are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0035] Please refer to the instruction manual Figure 1-5 The present invention provides a first embodiment of a waterproof structure, which mainly includes the following parts:

[0036] A metal shell 1 is characterized in that an opening 11 is provided on one side, and the outer edge of the opening 11 extends outward to form an outer edge 12 of a specific shape. The outer edge 12 is structured to include a straight portion 121, inclined portions 122 inclined downward from both sides of the straight portion 121, and a vertical portion 123 extending vertically downward from the end of the inclined portion 122. The end of the outer edge 12 is folded over to form a support portion 2, and the straight portion 121 and the support portion 2 together enclose a water storage space.

[0037] The waterproof shell 3 is installed on the outer edge 12, effectively covering and sealing the upper surface of the water storage space. To enhance stability, the waterproof shell 3 and the outer edge 12 are fixed along the straight direction of the support part 2 by at least two bolts 31. This structure improves the design of the opening 11 of the metal shell 1 and combines it with the waterproof shell 3 to form a water storage space. The water storage space can collect and store rainwater in the process shell, thereby significantly reducing the risk of moisture penetrating into the interior of the metal shell 1 through the joint between the opening 11 and the baffle.

[0038] In a possible example, the present invention improves the structure of the straight portion 121 so that the cross section of the straight portion 121 is inclined from the middle to both sides. At the same time, the inclined portion 122 is arranged at the inclined ends on both sides of the straight portion 121, and a water outlet is provided below the vertical portion 123 to discharge the accumulated water. Thus, the straight portion 121, the inclined portion 122, the vertical portion 123, the support portion 2 and the waterproof shell 3 together constitute a water guide space. By designing the cross section of the straight portion 121 to be inclined, the smooth discharge of rainwater is promoted, and the water outlet ensures the smooth discharge of water, thereby avoiding the generation of water accumulation.

[0039] In addition, in order to further improve the stability of the structure, the present invention connects at least one crossbeam 32 to the inner surface of the waterproof housing 3. Preferably, in this embodiment, there are two crossbeams 32, and the crossbeams 32 bridge the metal housing 1 frames on the left and right sides of the opening 11 in the direction of the straight portion 121. By introducing the crossbeam 32 structure, the connection strength between the waterproof housing 3 and the metal housing 1 is significantly enhanced, and structural deformation or damage caused by external forces is effectively prevented.

[0040] The working principle of the first embodiment is as follows:

[0041] The first embodiment mainly improves the design of the opening 11 of the metal shell 1 and combines it with the waterproof shell 3 to form a water storage space. The metal shell 1 is provided with an opening 11 on one side, and the outer edge 12 has a specific shape, including a straight portion 121, an inclined portion 122 and a vertical portion 123. The waterproof shell 3 is installed on the outer edge 12 to effectively close the water storage space. When rainwater falls on the waterproof shell 3, it will flow into the water storage space along a preset path instead of directly penetrating into the metal shell 1, thereby reducing the risk of water infiltration.

[0042] Please refer to the instruction manual Figure 1-6 The present invention provides a second embodiment of the waterproof structure. Based on the structure of the first embodiment, the present invention also provides a second embodiment. The second embodiment focuses on the strength problem of the connection between the waterproof housing 3 and the metal housing 1 and the problem of possible screw loosening, and further improves this part. The specific improvements are as follows:

[0043] In order to further optimize the fastening and waterproof performance of the mobile storage power supply, the present invention improves the internal structure of the water-conducting space. Considering that in the field environment, the power supply may be affected by external forces different from the fastening direction, thereby causing the threads to loosen, this embodiment introduces multiple support and fixing mechanisms.

[0044] Specifically, the present invention sets a plurality of first support frames 4 on the water-conducting space, and the first support frames 4 form plug-in grooves 41 with each other, and the length direction of each first support frame 4 is parallel to the straight portion 121 to ensure the stability of the structure. At least one plug-in board 5 parallel to the support portion 2 is plugged into the plug-in groove 41, and is fastened by screws 51 to achieve a stable connection. In addition, a second support frame 6 is placed in the accommodating channel 52 formed between adjacent support portions 2. The second support frame 6 is arranged vertically with the first support frame 4, and a connecting groove 61 is provided between adjacent second support frames 6, and its cross section is rectangular. The plug-in board 5 is equipped with a sliding portion 53 that cooperates with the connecting groove 61 to ensure smooth and stable sliding.

[0045] The above design strengthens the supporting structure of the water-conducting space in both horizontal and vertical dimensions, and also realizes a stable connection between the components through the plug-in board 5, thereby greatly improving the structural rigidity and stability of the connection between the opening 11 and the waterproof housing 3. At the same time, through the cleverly designed connecting groove 61 and the plug-in groove 41, the water that penetrates from the junction of the waterproof housing 3 and the opening 11 must pass through a tortuous path to reach the bottom of the water-conducting space, which not only effectively extends the water flow path, but also significantly reduces the risk of water penetrating into the metal housing 1.

[0046] In order to further improve the stability and accuracy of the movement of the plug board 5, the present invention designs dovetail grooves 531 on both sides of the sliding part 53, which are matched with the dovetail grooves 531 installed on the second support frame 6. The dovetail structure design provides a larger contact area to ensure a more stable sliding support.

[0047] The working principle of the second embodiment is as follows:

[0048] In the second embodiment, in order to further enhance the stability and waterproof performance of the structure, the internal structure of the water-conducting space is improved. By introducing the first support frame 4 and the second support frame 6, and the plug plate 5 and the connecting slot 61 matched therewith, the supporting structure is enhanced in both the horizontal and vertical dimensions, effectively improving the structural rigidity and stability of the connection between the opening 11 and the waterproof shell 3, and by the cleverly designed connecting slot 61 and the plug slot 41, the water flow path is extended, further reducing the risk of water penetrating into the metal shell 1.

[0049] Please refer to the instruction manual Figure 1-7 The present invention provides a third embodiment of the waterproof structure. The structure of the third embodiment has been greatly improved. Without considering the cost and materials, the improvement is mainly made to the structure of the second support frame 6. The specific structure is as follows:

[0050] A metal shell 1, wherein one side of the metal shell 1 has an opening 11, an outer edge 12 extends outward from the opening 11, and the outer edge 12 has a straight portion 121, an inclined portion 122 connected to both sides of the straight portion 121 and inclined downward, and a vertical portion 123 extending vertically downward along the inclined end of the inclined portion 122, the extended end of the outer edge 12 is folded to form a support portion 2, and the straight portion 121 and the support portion 2 form a water storage space;

[0051] The waterproof shell 3 is installed on the outer edge 12 and covers and closes the upper surface of the water storage channel. The waterproof shell 3 and the outer edge 12 are fixed by at least two bolts 31 along the straight direction of the support part 2.

[0052] Furthermore, the cross-section of the straight portion 121 is inclined from both sides of the middle of the straight portion 121, and inclined portions 122 are provided on both sides of the straight portion 121. A vertical portion 123 extends downward from the inclined end of the inclined portion 122, and a water outlet for water to flow out is provided below the vertical portion 123. The straight portion 121, the inclined portion 122, the vertical portion 123, the support portion 2 and the waterproof shell 3 form a water guide space.

[0053] Furthermore, the inner surface of the waterproof housing 3 is connected to at least one crossbeam 32 , and the crossbeam 32 bridges the frames of the metal housing 1 on the left and right sides of the opening 11 in the straight direction of the straight portion 121 .

[0054] Furthermore, a plurality of first support frames 4 are provided on the water-conducting space, and two adjacent first support frames 4 are formed with a plug-in groove 41, and the length direction of the first support frame 4 is parallel to the straight direction of the above-mentioned straight segment, and at least one plug-in plate 5 is plugged into the plug-in groove 41, and the plug-in plate 5 is arranged parallel to the above-mentioned support portion 2, and at least one screw 51 passes through the support plate and the plug-in plate 5 and locks the support plate and the plug-in plate 5.

[0055] Furthermore, an accommodating channel 52 is formed between two adjacent supporting portions 2 perpendicular to the length direction of the first supporting frame 4 , and a second supporting frame 6 whose length direction is perpendicular to the length direction of the first supporting frame 4 is placed in the accommodating channel 52 .

[0056] Furthermore, a connecting slot 61 is provided between two adjacent second support frames 6 , the cross section of the connecting slot 61 is quasi-rectangular, and the plug board 5 has a sliding portion 53 that matches the connecting slot 61 structure.

[0057] Furthermore, dovetail grooves 531 are formed on two side surfaces of the sliding portion 53 , and a dovetail slider that matches the dovetail grooves 531 is installed on the second support frame 6 .

[0058] In this solution, a first accommodation space 62 is constructed between the top surface of the second support frame 6 and the top surface of the water guide space. At the same time, a strip groove 611 is designed on the top surface of the connecting chute 61 so that water flows from the first accommodation space 62 into the connecting chute 61. A second accommodation space 54 is formed between adjacent plug boards 5.

[0059] In the second accommodating space 54, a rotating shaft 7 is installed on the top of one of the plug-in boards 5. The rotating shaft 7 is rotatably connected by connecting the two sides of the sliding groove 61. A sealing gasket 8 that can be rolled or unfolded is installed on the rotating shaft 7. When the sealing gasket 8 is unfolded, it can effectively close the strip groove 611. A first gear 71 is arranged opposite the rotating shaft 7, and a second gear 72 is meshed with the first gear 71. A rope 73 surrounds the second gear 72, and one end is connected to a connecting plate 74 hinged on the plug-in board 5, and a spring 75 is installed between the connecting plate 74 and the plug-in board 5, and the other end of the rope 73 is fixed on the sealing gasket 8.

[0060] In addition, a limit block 76 is fixed on the plug-in board 5 opposite to the rotating shaft 7 in the second accommodating space 54 , and a rectangular through hole 761 is provided on the limit block 76 to allow the rack 77 to partially pass through, and the tooth surface of the rack 77 keeps in contact with the first gear 71 .

[0061] The above structure works together with the support frame, waterproof housing 3 and other components to form a complete waterproof system, which has two working modes: in drainage mode, when there is less water accumulation, the water will be discharged smoothly along the preset tortuous path; and when the water level rises to a certain level, the system will accurately trigger the deployment of the sealing pad 8 through the mechanical linkage of the rotating shaft 7, gears and ropes 73, thereby blocking the entrance of the tortuous drainage path. This transformation puts the waterproof system into a closed mode, effectively preventing a large amount of water from flowing into the path, ensuring that the system can provide stable protection in various environments.

[0062] In summary, the waterproof structure of the present invention and the energy storage power supply based on the waterproof structure, by improving the opening 11 part of the metal shell 1 and combining it with the waterproof shell 3, form an effective water storage space, which can collect and temporarily store moisture flowing through the shell, ensuring that moisture is not easy to penetrate into the interior of the metal shell 1 from the connection between the opening 11 and the baffle.

[0063] Based on the above embodiments, the present invention further proposes an energy storage power supply based on the waterproof structure, and the energy storage power supply adopts the waterproof structure of any one of the above embodiments.

[0064] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
