Description

Technical Field

[0001] This application relates to the technical field of energy storage, and in particular to a waterproof structure for an energy storage device and an energy storage device. Background Art

[0002] At present, with the booming development of the energy storage industry, the demand is increasing, and the requirements for energy storage cabinets or container boxes are also getting higher and higher. Especially for waterproofing, the protection level of the box can often represent the lifespan of the internal electrical components. And for safety protection on the circuit, usually a spray test is carried out on the box at the time of factory to check the waterproof performance of the box.

[0003] However, for the above related technologies, the inventor believes that there are defects as follows: When the manufacturer produces the box body, in order to ensure that the door body is flush with the surface of the box body, the door frame is usually welded to the box body in an embedded design. This welding process usually uses manual welding, and sometimes there will be problems of false welding, and it is difficult to be detected. The liquid outside the box body is easy to penetrate into the box body from the false welding point, resulting in short - circuit damage of the electrical components inside the box body. Summary of the Invention

[0004] One or more embodiments of this application provide a waterproof structure for an energy storage device and an energy storage device to solve or at least partially alleviate the problem of weak waterproof performance in related technologies.

[0005] One or more embodiments of this application provide a waterproof structure for an energy storage device and an energy storage device, and the technical solution is as follows:

[0009] In some embodiments, a first channel is provided in the first seal section, and first drain openings communicating with the first channel are provided at both ends of the first seal section. The first drain openings are located below the door opening; a second channel is provided in the second seal section, and second drain openings communicating with the second channel are provided at both ends of the second seal section. The second drain openings are located below the door opening.

[0010] In some embodiments, the height of the first drain opening is lower than the height of the second seal section.

[0011] In some embodiments, a water retaining edge is provided on the side of the receiving part away from the box body, and the water retaining edge is adapted to make the liquid received by the receiving part flow away from the box body.

[0012] In some embodiments, a raised part is provided on the receiving part. The raised part protrudes from the door opening, and the water guide groove is located below the raised part; the water retaining edge is provided on the raised part.

In addition, the optimized door frame can be fixed and synchronously welded by the cooperation of the top cover and the support body, so the overall welding workload can be reduced and the production efficiency can be improved.

[0018] (2) By optimizing the structure of the seal, the waterproof structure of this application splits the seal into a first seal section and a second seal section, which can reduce the assembly difficulty between the seal and the door frame, improve the assembly efficiency, facilitate the overall adjustment of the seal, and solve the problem of the tightness of the seal installation. At the same time, the drainage methods of the first seal section and the second seal section are also optimized, making it difficult for liquid to flow into the box body from the door opening.

[0033] One or more embodiments of the present application disclose a waterproof structure for an energy storage device, referring to Figures 1 to 6, including a support body 1, a top cover 2 and a water guiding assembly. The support body 1 is located on the side of the box body, the top cover 2 is located on the top of the box body, the support body 1 and the top cover 2 are spliced and matched. The water guiding assembly includes a water guiding member and a receiving portion 4. A water guiding groove 3 is formed on the water guiding member, and part of the water guiding groove 3 is arranged at the support body 1. One end of the receiving portion 4 is connected to the water guiding member, and the other end of the receiving portion extends towards the top cover 2 outside the support body 1. The receiving portion 4 is adapted to be connected with the top cover 2, and the receiving portion 4 is adapted to receive and guide the liquid to flow into the water guiding groove 3. The receiving portion 4 can receive the liquid left from the upper part of the box body above the water guiding groove 3. The opening of the water guiding groove 3 at the support body 1 faces upward. Since the receiving portion 4 and the water guiding groove 3 can be integrally connected, the liquid can flow smoothly into the water guiding groove 3, reducing the probability of the liquid seeping into the box body from the joint.

[0034] In this application, the liquid includes liquids such as rainwater in the external environment outside the box body.

[0035] Such as Figure 1 and 2 In the embodiment shown, when the box body is set as an openable structure, the waterproof structure of the embodiment of this application may further include a door frame 5 and a door body 6. A door opening 51 is formed on the door frame 5 for operators to enter or operate. The water guiding groove 3 is formed around the door opening 51 to guide the liquid flowing towards the door opening 51, reducing the probability of the liquid entering the door opening 51. The receiving portion 4 is formed on the top of the door frame 5. The receiving portion 4 cooperates with the top cover 2 and the support body 1 of the box body to guide the liquid to flow to the water guiding groove 3.

[0036] In the traditional box body assembly method, the side of the box body requires the support body 1 as a basic framework to help fix structures such as the door frame 5. The door frame 5 is usually installed in an embedded form under the support body 1, and the door frame 5 is welded under the support body 1. Also, because the water guiding groove 3 is arranged around the door frame 5, due to the interference between the embedded installation and the structure of the water guiding groove 3, the welding space is limited, so it is easy to cause false welding. However, the existence of the receiving portion 4 can change the welding position of the water guiding groove 3 to the vicinity of the top cover 2 above the support body 1, so as to increase the post-welding space, reduce the welding difficulty, and thus reduce the occurrence of false welding, so as to improve the overall waterproof performance of the box body.

[0037] Such as Figure 1 In the embodiment shown, the receiving portion 4 is provided with a water retaining edge 41 on the side away from the box body. The water retaining edge 41 is adapted to make the liquid received by the receiving portion 4 flow away from the box body. The water retaining edge 41 can play a role in guiding and water retaining, reducing the liquid flowing along the receiving portion 4 to the water guiding groove 3, so as to reduce the drainage pressure of the water guiding groove 3, and thus reduce the accumulation of water at the water guiding groove 3.

[0038] Such as Figure 1In the illustrated embodiment, a convex portion 42 is provided on the receiving portion 4. The convex portion 42 protrudes from the door opening 51, and the water guide groove 3 is located below the convex portion 42. The convex portion 42 can, to a certain extent, cause the liquid flowing down along the receiving portion 4 to drip and flow out in advance outside the door opening 51, so as to reduce the drainage pressure of the water guide groove 3, thereby reducing the ponding at the water guide groove 3.

[0039] As Figure 1 In the illustrated embodiment, the convex portion 42 is arranged in cooperation with the shape of the support body 1. The water guide groove 3 is located below the support body 1, and the overall structure of the receiving portion 4 can be structurally strengthened by using the support body 1.

[0040] As Figure 1 In the illustrated embodiment, a water retaining edge 41 is provided on the convex portion 42. The water retaining edge 41 can further enhance the ability of the convex portion 42 to make the liquid flowing down along the receiving portion 4 flow out outside the door opening 51, so as to reduce the drainage pressure of the water guide groove 3, thereby reducing the ponding at the water guide groove 3.

[0041] A sealing member 31 is provided on the water guide groove 3 of the water guiding member. The door body 6 is adapted to cover the door opening 51, and the door body 6 is in contact and sealed with the sealing member 31. Under the combined action of the water guide groove 3 and the sealing member 31, the liquid flowing into the door opening 51 can be restricted.

[0042] In some embodiments, the sealing member 31 preferably uses a flexible sealing strip made of materials such as rubber. One side of the sealing member 31 is adapted to be fixedly clamped in cooperation with the edge of the water guide groove 3.

[0043] It can be understood that the water guide groove 3 with the receiving portion 4 in the present application, in addition to being used in combination with the door frame 5, can also be used as an independent waterproof structure on the box body. By arranging the water guide groove 3 on the side of the box body, the part of the water guide groove 3 with the opening upward can reduce the liquid flowing from above the box body and the side of the box body to below the water guide groove 3.

[0044] As Figure 1 In the illustrated embodiment, the upper end of the receiving portion 4 extends below the edge of the top cover 2. The receiving portion 4 can be welded and cooperated with the top cover 2, and directly receive liquids such as rainwater flowing down from the top cover 2, increasing the drainage effect.

[0045] As Figure 2 and 3In the illustrated embodiment, the seal 31 includes a first seal section 311 and a second seal section 312. The first seal section 311 and the second seal section 312 are arranged on the door frame 5 in a vertically separated form. Here, the vertical separation means that the first seal section 311 is located above the door frame 5 compared to the second seal section 312, and the second seal section 312 is located below the door frame 5 compared to the first seal section 311. The first seal section 311 and the second seal section 312 are adapted to be connected below the door opening 51 to ensure the integrity of the waterproof performance of the seal 31 above the door opening 51. Even if there is a leak at the connection between the first seal section 311 and the second seal section 312, since the amount of liquid that the seal 31 needs to block below the door opening 51 is relatively small, the probability of leakage is relatively low.

[0046] Generally, the seal 31 has a hollow structure and achieves the sealing effect through structural deformation. Usually, through holes are provided on the seal 31 to help the seal 31 exhaust air and deform, further enhancing the sealing effect. By designing the seal 31 as a split structure, compared with the design of arranging a traditional single-piece sealing strip on the door frame 5, the efficiency of assembling the seal 31 can be effectively improved. And due to the increase in the disconnection points, the installation allowance of the seal 31 can also be increased, which can solve the problem that it is difficult to adjust the seal 31 when it is installed too loose or too tight.

[0047] In some embodiments, the gap at the connection between the first seal section 311 and the second seal section 312 is sealed by caulking.

[0048] In some embodiments, a first channel 3111 is provided inside the first seal section 311. The through hole is connected to the first channel 3111. First drain ports 3112 communicating with the first channel 3111 are provided at both ends of the first seal section 311. The first drain ports 3112 are located below the door opening 51, and the first drain ports 3112 are lower than the door opening 51, which can reduce the probability of the liquid flowing out from the first drain ports 3112 entering the door opening 51 and enhance the waterproof performance.

[0049] In some embodiments, the first drain ports 3112 are located at the lowest points of the first seal section 311, which can drain the liquid inside the first seal section 311 as much as possible and reduce the probability of water accumulation inside the first seal section 311.

[0050] In some embodiments, a second channel 3121 is provided inside the second seal section 312. The through hole is connected to the second channel 3121. Second drain ports 3122 communicating with the second channel 3121 are provided at both ends of the second seal section 312. The second drain ports 3122 are located below the door opening 51, and the second drain ports 3122 are lower than the door opening 51, which can reduce the probability of the liquid flowing out from the second drain ports 3122 entering the door opening 51 and enhance the waterproof performance.

[0051] In some embodiments, the second drain opening 3122 is located at the lowest point of the second sealing section 312, which can drain the liquid in the second sealing section 312 as much as possible and reduce the probability of water accumulation in the second sealing section 312.

[0052] As Figure 3 shown in the embodiment, the height of the first drain opening 3112 is lower than the height of the second sealing section 312. Specifically, the height of the first drain opening 3112 is lower than the height of the lowest point of the second sealing section 312. According to the sealing strip installation method in the prior art, the first sealing section 311 and the second sealing section 312 are connected together. Even if the first sealing section 311 and the second sealing section 312 are separately arranged, the lowest point of the first sealing section 311 is flush with the lowest point of the second sealing section 312. When the water volume is large, the water will flow down along the first sealing section 311 outside the box body and then flow and transition to the second sealing section 312. At this time, the water will enter from the gap between the first sealing section 311 and the second sealing section 312. However, in this application, by optimizing the connection between the first sealing section 311 and the second sealing section 312, the liquid flowing out from the second drain opening 3122 can be directly discharged from below the second sealing section 312, thereby reducing the probability of the liquid discharged from the first sealing section 311 entering the door opening 51.

[0053] As Figure 2 shown in the embodiment, the first sealing section 311 is arranged in an n-shaped structure on the water guide grooves 3 above and on both sides of the door opening 51, and the second sealing section 312 is arranged in a straight line structure on the water guide grooves 3 below the door opening 51. The first sealing section 311 and the second sealing section 312 are at the corners on both sides of the bottom of the door opening 51 and are respectively connected as two sides of the corner for cooperation. It can be understood that the split design of the seal 31 can also reduce the number of corners, thereby reducing the probability of water accumulation and retention.

[0054] It should be noted that the split design of the seal 31 can be used separately from the water guide groove 3 and can also achieve the corresponding waterproof effect.

[0055] As Figures 4 to 6 shown in the embodiment, a linkage lock body 7 is provided on the door body 6. The linkage lock body 7 includes an operation part 71, a first locking tongue part 72, a second locking tongue part 73, and a connecting rod part 74. The connecting rod part 74 connects the operation part 71, the first locking tongue part 72, and the second locking tongue part 73. The operation part 71 is adapted to make the first locking tongue part 72 and the second locking tongue part 73 move synchronously. The first locking tongue part 72 is adapted to rotate and lock with the left side and / or the right side of the door frame 5 (refer to Figure 4 the left and right directions in), and the second locking tongue part 73 is adapted to slide and lock with the upper side and / or the lower side of the door frame 5. Through the operation part 71, multi-point locking between the door body 6 and the door frame 5 can be realized, which is convenient to operate and has a stable structure.

[0056] In some embodiments, the operating part 71 is a slider structure, which is connected to the link part 74 through a gear rack. When the operating part 71 slides, it can drive the link parts 74 on both sides to move towards each other.

[0057] In some embodiments, the second locking tongue part 73 is a pulley structure, which can roll along the door frame 5 and engage when contacting the door frame 5.

[0058] As Figure 4 In the shown embodiment, the linkage lock body 7 is adapted to cooperate with three sides adjacent to the door frame 5 to form a five-point locking. By increasing the number of locking points, the door body 6 can be effectively pressed against the sealing member 31, improving the sealing performance.

[0059] Specifically, the way for the linkage lock body 7 to perform five-point locking is that one first locking tongue part 72 is connected to the operating part 71. Two first locking tongue parts 72, two second locking tongue parts 73 and two link parts 74 are symmetrically arranged on the upper and lower sides of the operating part 71. Three first locking tongue parts 72 are adapted to rotate and lock with the left side (long side) or the right side (long side) of the door frame 5, and two second locking tongue parts 73 are adapted to slide and lock with the upper and lower sides (short sides) of the door frame 5, which can effectively improve the locking strength and locking stability.

[0060] When the first locking tongue part 72 is connected to the operating part 71, the first locking tongue part 72 and the operating part 71 are connected through a gear rack, which can convert the linear motion of the operating part 71 into the rotational motion of the first locking tongue part 72.

[0061] One or more embodiments of the present application also disclose an energy storage device, including the waterproof structure of any of the above embodiments. This energy storage device generally refers to a device with electrical components inside and a housing and cabinet for waterproofing, sealing and protection outside, and there are openable parts on the housing and cabinet. In particular, the waterproof structure of the present application can enhance the waterproof performance of the openable parts on the housing and cabinet.

Those skilled in the art should understand that the present application is not limited by the above embodiments.
