[0030] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.
[0031] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.
[0032] The following is combined Figures 1 to 8The energy storage box and device provided in this application will be described in detail through specific embodiments and application scenarios.
[0033] It should be noted that in this application, the first direction is the first horizontal direction or the front-back direction of the energy storage device, the second direction is the vertical direction or the up-down direction of the energy storage device, and the third direction is the second horizontal direction or the left-right direction of the energy storage device. The second horizontal direction is perpendicular to the first horizontal direction.
[0034] Reference Figure 1 and Figure 2 Some embodiments of the application disclose an energy storage box 100, the structure of which includes: a first shell 110, a second shell 120, a first seal 130 and a second seal 140.
[0035] Reference Figures 1 to 5 Specifically, the first housing 110 has an opening 111 and a first mating surface 112, the first mating surface 112 being arranged circumferentially around the opening. The second housing 120 has a second mating surface 121 that mates with the first mating surface 112, and the second mating surface 121 and the first mating surface 112 are mated together in a first direction to close the opening 111. A first sealing member 130 is disposed between the mating contours of the first mating surface 112 and the second mating surface 121, and is continuously arranged circumferentially around the opening 111 to form a first waterproof layer. A second sealing member 140 is disposed between the first mating surface 112 and the second mating surface 121, and is located outside the first sealing member 130 in a second direction to form a second waterproof layer.
[0036] In the above embodiment, by continuously surrounding the opening 111 with a first sealing element 130, a first waterproof layer is formed, directly sealing the opening 111 and serving as the main waterproof structure to block most possible water intrusion sources. Simultaneously, a second sealing element 140 is disposed outside the first sealing element 130 in the second direction, forming a second waterproof layer outside the protective boundary of the first sealing element 130, serving as a secondary waterproof structure. In this way, the first sealing element 130 reduces the probability of moisture entering the storage tank, while the second sealing element 140 ensures the airtightness of the energy storage tank 100. This dual-sealing structure greatly enhances the sealing performance of the energy storage tank 100. Even if the joint between the first shell 110 and the second shell 120 is exposed at the top, it can effectively prevent external moisture and humidity from entering the tank, protecting the internal battery components and other electrical components from environmental factors and reducing the risk of short circuits, corrosion, and other failures caused by moisture and water ingress. This contributes to improving the reliability and service life of the energy storage device.
[0037] Reference Figures 2 to 4In some embodiments, a first groove 122 is provided on the second mating surface 121. The first groove 122 is continuously arranged around the opening in the circumferential direction, and the first seal 130 is embedded in the first groove 122. The first groove 122 provides a precise installation position for the first seal 130, ensuring that the first seal 130 will not shift or fall off during the mating process, thereby maintaining the continuity of the sealing path. At the same time, the sidewalls of the first groove 122 can limit the lateral displacement of the first seal 130 under pressure or vibration, avoiding local sealing failure caused by the displacement of the first seal 130.
[0038] It is understandable that, in actual processing, a first groove 122 can also be provided on the first mating surface 112, or grooves can be provided on both the first mating surface 112 and the second mating surface 121, and the first groove 122 is formed after the two are mated.
[0039] Similarly, in some embodiments, a second groove 123 is provided on the second mating surface 121. The second groove 123 is located outside the first groove 122 in the second direction; wherein, the second sealing member 140 is embedded in the second groove 123.
[0040] It is understandable that, in actual processing, a second groove 123 can also be provided on the first mating surface 112, or grooves can be provided on both the first mating surface 112 and the second mating surface 121, and the two are mated together to form the second groove 123.
[0041] In some embodiments, the first seal 130 and the second seal 140 are made of the same material, and the compression amount of the second seal 140 is less than that of the first seal 130.
[0042] In practical applications, using the same material for both the first seal 130 and the second seal 140, with identical thermal expansion coefficients and weather resistance, avoids delamination of the sealing interface due to temperature-induced deformation differences, facilitating management. Furthermore, the first seal 130, as the primary waterproofing structure, serves as the final line of defense for the waterproof performance of the energy storage tank 100. High compression results in higher contact stress between the first seal 130 and the mating surface, leading to stronger sealing performance. The second seal 140, as the secondary waterproofing structure, uses a smaller compression amount to maintain elasticity. Even if the primary seal experiences a decrease in localized stress due to long-term compression or external damage, the secondary seal can still maintain its sealing performance through elastic recovery, thus preventing the dual-seal structure from failing simultaneously due to excessive stress.
[0043] In the above embodiment, the depth of the first groove 122 is less than the depth of the second groove 123, and the thickness of the first seal 130 is the same as the thickness of the second seal 140.
[0044] In this way, the first seal 130, due to the shallow depth of the first groove 122, is subjected to forced high compression during assembly, quickly forming the main waterproof structure; while the second seal 140, due to the greater depth of the second groove 123, experiences less compression during assembly, thus maintaining a low preload elastic state. The first seal 130 and the second seal 140 have the same thickness, and the compression is controlled by the depth of the first groove 122 and the second groove 123. During assembly, no manual identification or equipment calibration is required; installation can be performed directly according to the groove positions. Simultaneously, it avoids sealing failure caused by mixing seals (such as mistakenly installing a high-compression seal in a low-compression groove).
[0045] Reference Figure 3 In some embodiments, the second groove 123 includes a body segment 1231 that extends along a third direction. In practical use, the risk of liquid ingress mainly comes from the top. This application extends the body segment 1231 along a third direction to form a linear groove, restricting the installation position of the second seal 140 above the first seal 130. This ensures that the second seal 140 only forms a barrier above the first seal 130, maintaining the core waterproof function while reducing the total number of seals used, thereby helping to reduce costs.
[0046] In some embodiments, the second groove 123 further includes a water guide section 1232 that extends from the body section 1231 toward the side where the first seal 130 is located.
[0047] In the above embodiment, the water guiding section 1232 extends from the body section 1231 toward the first seal 130 in a slope or arc-shaped structure to form a fluid guiding path, which directs the liquid away from the main sealing area, thereby preventing the liquid from accumulating at the sealing interface and protecting the first seal 130.
[0048] In practical applications, the water guiding section 1232 has two sections, which are respectively set at both ends of the body section 1231. By setting the water guiding section 1232 at both ends of the body section 1231, both sides of the main sealing area are covered, avoiding the problem of incomplete water guiding on one side.
[0049] Reference Figure 6 and Figure 7 In some embodiments, the first sealing member 130 includes a waterproof adhesive strip 131 and a connector 133. Specifically, the waterproof adhesive strip 131 has a through hole 132, and the connector 133 is inserted into the through hole 132.
[0050] In practical use, the two ends of the waterproof strip 131 are joined together by the insertion and mating of the connector 133 and the through hole 132 to form a circumferentially closed first sealing element 130. In this way, the waterproof strip 131 can be cut to the required length according to actual needs, thereby completing the installation of the first sealing element 130 and avoiding the waste or splicing mismatch problems caused by the fixed size of traditional sealing rings.
[0051] It is understood that the first sealing element 130 can also directly adopt the structure of an integrated sealing ring, and this embodiment is not limited thereto.
[0052] Reference Figure 8 In some embodiments, this application also provides an energy storage device 200, the structure of which includes the energy storage box 100, battery 210 and inverter 220 provided in any of the above embodiments.
[0053] Specifically, the battery 210 is installed inside the energy storage box 100 to store electrical energy. The inverter 220 is electrically connected to the battery 210 to convert the electrical energy converted from solar energy from DC to AC to meet the power needs of different devices.
[0054] In the above embodiments, since the energy storage device 200 has the energy storage box 100 provided in any of the above embodiments, it has the beneficial effects of any of the above embodiments, which will not be repeated here.
