[0012] In some embodiments, the connecting plate includes a first vertical portion, a horizontal portion, and a second vertical portion. The horizontal portion is located between the first vertical portion and the second vertical portion. One end of the horizontal portion is connected to the first vertical portion, and the other end of the horizontal portion is connected to the second vertical portion. The first vertical portion, the horizontal portion, and the second vertical portion enclose a limiting groove. The opening of the limiting groove faces the support cover. At least a portion of the fixing member is located in the limiting groove, and the end of the fixing member facing away from the lifting ring abuts against the horizontal portion.

[0013] According to another aspect of this application, an energy storage cabinet is provided, including a cabinet body and an insulating cover as described above, the insulating cover being disposed on the cabinet body and detachably connected to the cabinet body.

The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of this application.

[0028] Unless otherwise stated, the term "multiple" as used herein refers to two or more.

[0029] The following description, in conjunction with the accompanying drawings, will illustrate some embodiments of this application. The technical features described in the different embodiments of this application below can be combined with each other as long as they do not conflict with each other.

[0030] Please see Figure 1 and Figure 2 This application provides an energy storage cabinet 1, which includes a cabinet body 2000 and a heat insulation cover 1000. The heat insulation cover 1000 is placed on the cabinet body 2000 and is detachably connected to the cabinet body 2000.

[0031] The cabinet 2000 can house heat sources such as energy storage devices or electronic equipment.

[0032] It is understandable that the detachable connection between the heat insulation cover 1000 and the cabinet 2000 can be a snap-fit, screw-fit, etc.

[0033] In some embodiments, please refer to Figure 2The energy storage cabinet also includes a connecting column 3000, which is located inside the cabinet body 2000 and is detachably connected to the heat insulation cover 1000. The heat insulation cover 1000 provides heat insulation, reducing the amount of external heat entering the cabinet body 2000 and reducing the amount of heat lost from the cabinet body 2000 to the outside, thus helping to maintain the internal temperature of the cabinet body 2000 within a stable and suitable range.

[0034] In some embodiments, the energy storage cabinet 1 further includes a base plate 4000, and the end of the connecting column 3000 facing away from the heat insulation cover plate 1000 is detachably connected to the base plate 4000. The base plate 4000 and the heat insulation cover plate 1000 are arranged opposite to each other.

[0035] In some embodiments, please refer to Figure 3 and Figure 4 The heat insulation cover 1000 includes a support cover 10, a reinforcing rib 20, a first heat insulation cotton 30, and a second heat insulation cotton 40. The reinforcing rib 20 is connected to the support cover 10. The first heat insulation cotton 30 is disposed on the side of the support cover 10 away from the reinforcing rib 20, and the second heat insulation cotton 40 is disposed on the side of the reinforcing rib 20 away from the support cover 10. The second heat insulation cotton 40 is detachably connected to the reinforcing rib 20.

[0036] In some embodiments, such as Figures 4-6 As shown, along the thickness direction of the support cover 10, the support cover 10 has a first wall 10b and a second wall 10c arranged opposite to each other. The first wall 10b is located closer to the cabinet 2000 of the energy storage cabinet 1 than the second wall 10c, and the second wall 10c is located away from the cabinet 2000 of the energy storage cabinet 1 than the first wall 10b.

[0037] In some embodiments, the support cover 10 includes a support plate 102 and a plurality of extension plates 103 extending from the periphery of the support plate 102. The support plate 102 and the plurality of extension plates 103 enclose a mounting cavity 10a, and a reinforcing rib 20 is located within the mounting cavity 10a. In some embodiments, the first wall 10b and the second wall 10c are both located on the support plate 102.

[0038] In some embodiments, the first wall 10b is the inner wall of the bottom of the mounting cavity 10a, and the second wall 10c is the outer wall of the bottom of the mounting cavity 10a. It should be noted that the bottom of the mounting cavity 10a is usually positioned opposite to the opening of the mounting cavity 10a, and the reinforcing ribs 20 and other components usually enter from the opening of the mounting cavity 10a and are installed inside the mounting cavity 10a.

[0039] In some embodiments, such as Figures 4-6As shown, the first heat insulation cotton 30 is disposed on the side of the second wall 10c away from the reinforcing rib 20. The first heat insulation cotton 30 is used to prevent external heat from entering the support cover 10. When the energy storage cabinet 1 is in a high-temperature external environment, the first heat insulation cotton 30 can reduce the amount of external heat entering the mounting cavity 10a of the support cover 10.

[0040] In some embodiments, such as Figures 4-6 As shown, the second heat insulation cotton 40 is disposed on the side of the reinforcing rib 20 away from the support cover 10. The second heat insulation cotton 40 is detachably connected to the reinforcing rib 20, and a heat insulation cavity 20a is provided between the second heat insulation cotton 40 and the support cover 10. When the energy storage cabinet 1 is in a high-temperature external environment, external heat enters the interior of the support cover 10 through the support cover 10. Since air has a low thermal conductivity, the heat insulation cavity 20a can reduce the conduction of external heat towards the cabinet 2000.

[0041] Understandably, when the energy storage cabinet 1 is in a high-temperature external environment, external heat enters the mounting cavity 10a through the support cover 10. Since air has a low thermal conductivity, the insulation cavity 20a reduces the conduction of external heat towards the cabinet body. The external heat entering the mounting cavity 10a is then insulated by the second insulation cotton 40, thereby reducing the conduction of external heat into the cabinet body 2000 and ensuring that, even in a high-temperature external environment, less external heat enters the cabinet body 2000.

[0042] In some embodiments where an installation cavity 10a is provided, the heat insulation cavity 20a communicates with the installation cavity 10a.

[0043] In some embodiments, such as Figures 4-6 As shown, the reinforcing rib 20 is disposed on the side of the first wall 10b opposite to the second wall 10c, and the reinforcing rib 20 is connected to the support cover 10. The inclusion of the reinforcing rib 20 can improve the strength of the entire heat insulation cover 1000.

[0044] In some embodiments, the reinforcing rib 20 includes a fixed plate 201 and a plurality of connecting plates 202 connected in sequence. The plurality of connecting plates 202 enclose a heat insulation cavity 20a. The fixed plate 201 is located inside the heat insulation cavity 20a. One of the two oppositely arranged connecting plates 202 is connected to one end of the fixed plate 201, and the other connecting plate 202 is connected to the other end of the fixed plate 201. This arrangement enables the reinforcing rib 20 to form a stable frame structure. The arrangement of the fixed plate 201 not only enhances the overall rigidity of the reinforcing rib 20, but also effectively disperses stress and avoids structural deformation due to excessive local stress.

[0045] It should be noted that in some other embodiments, the heat insulation cavity 20a may not be located on the reinforcing rib 20, and the heat insulation cavity 20a may be formed directly by a predetermined space between the second heat insulation cotton 40 and the support cover 10.

[0046] In some embodiments, please refer to the following: Figure 7 The connecting plate 202 includes a first vertical part 2021, a horizontal part 2022, and a second vertical part 2023. The horizontal part 2022 is located between the first vertical part 2021 and the second vertical part 2023. One end of the horizontal part 2022 is connected to the first vertical part 2021, and the other end of the horizontal part 2022 is connected to the second vertical part 2023. The first vertical part 2021, the horizontal part 2022, and the second vertical part 2023 enclose each other to form a limiting groove 202a. The opening of the limiting groove 202a faces the support cover 10. At least a portion of the fixing member 80 is located in the limiting groove 202a. One end of the fixing member 80 away from the lifting ring 70 abuts against the horizontal part 2022. The setting of the limiting groove 202a can reduce the movement of the fixing member 80 and thus play a limiting role for the fixing member 80.

[0047] In some embodiments, such as Figures 4-6 As shown, the heat insulation cover 1000 includes a pressure plate 50, which is located on the side of the second heat insulation cotton 40 away from the reinforcing rib 20. The pressure plate 50 is detachably connected to the reinforcing rib 20. The pressure plate 50 can reduce the direct exposure of the second heat insulation cotton 40 to the internal environment of the cabinet 2000. The pressure plate 50 itself has a certain strength, which can provide additional structural support for the second heat insulation cotton 40 and enhance the stability of the overall heat insulation structure. At the same time, the pressure plate 50 can further compress the second heat insulation cotton 40, making it fit more closely to the reinforcing rib 20 and enhancing the heat insulation performance.

[0048] It should be noted that when the heat insulation cover 1000 is normally used and installed on the cabinet 2000, the protective cover 60 on it is exposed to the external environment, while the pressure plate 50 on it is located in the internal environment of the energy storage cabinet 1.

[0049] It is understandable that the detachable connection between the second insulation cotton 40 and the reinforcing rib 20, and the detachable connection between the pressure plate 50 and the reinforcing rib 20, include but are not limited to threaded connection, screw connection, snap-fit, etc.

[0050] In some embodiments, such as Figures 3-5 As shown, the heat insulation cover includes a protective cover 60, which covers the support cover 10. The protective cover 60 serves to cover and protect the first heat insulation cotton 30, the support cover 10, the reinforcing rib 20, and the second heat insulation cotton 40. The first heat insulation cotton 30 is located between the protective cover 60 and the support cover 10. The protective cover 60 can prevent the first heat insulation cotton 30 from being subjected to mechanical damage, vibration, or damage from the external environment during use, thereby extending the service life of the first heat insulation cotton 30.

[0051] In some embodiments, the protective cover 60 includes a cover body 601 and a plurality of side plates 602 extending from the periphery of the cover body 601. The plurality of side plates 602 enclose a protective cavity 60a. The first heat insulation cotton 30, the support cover 10, the reinforcing rib 20 and the second heat insulation cotton 40 are all located in the protective cavity 60a. The side plates 602 on the protective cover 60 are used to connect with the cabinet body 2000 of the energy storage cabinet 1.

[0052] In some embodiments, the heat insulation cover 1000 includes a lifting ring 70 and a fixing member 80. The lifting ring 70 is connected and cooperates with the fixing member 80 to fix the lifting ring 70 to the support cover 10. The lifting ring 70 can cooperate with an external mechanism, which is beneficial for the external mechanism to drive the heat insulation cover 1000.

[0053] In some embodiments, such as Figures 4-6 As shown, the fastener 80 is located on the side of the reinforcing rib 20 near the support cover 10. The lifting ring 70 includes a ring buckle 701 and a connecting post 702 connected to the ring buckle. The ring buckle 701 abuts against the outer surface of the protective cover 60, and the connecting post 702 connects to the fastener 80. The cooperation between the connecting post 702 on the lifting ring 70 and the fastener 80 makes the structure of the heat insulation cover 1000 more compact and enhances the overall mechanical strength. The ring buckle 701 on the lifting ring 70 provides a convenient handling point for the heat insulation cover 1000 or the energy storage cabinet 1, allowing workers or equipment to easily move the heat insulation cover 1000 or the energy storage cabinet 1 without direct contact with the heat insulation cover 1000.

[0054] In some embodiments, please refer to the following: Figure 7 The fastener 80 includes a connecting part 801 and a fixing part 802 connected to the connecting part 801. The fixing part 802 is fixed to the reinforcing rib 20. The connecting part 801 passes through the support cover 10, the first heat insulation cotton 30, and the protective cover 60. The connecting part 801 is connected to the connecting post 702. It can be understood that the fixing part 802 can be fixed to the reinforcing rib 20 by screwing, welding, riveting, or other means.

[0055] In some embodiments, the support cover 10 is provided with a third through hole 101 communicating with the mounting cavity 10a. The first heat insulation cotton 30 is provided with a second through hole 301, which is disposed opposite to the third through hole 101. The protective cover 60 is provided with a first through hole 601, which is disposed opposite to the second through hole 301. The connecting portion 801 of the fixing member 80 passes through the first through hole 601, the second through hole 301, and the third through hole 101. The connecting post 702 on the lifting ring 70 is screwed to the fixing member 80, thereby realizing the connection between the lifting ring 70 and the fixing member 80.

[0056] In some embodiments, the heat insulation cover also includes a heat insulation sheet 90, which is located on the side of the reinforcing rib 20 away from the support cover 10. The heat insulation sheet 90 is used to block external heat from being conducted from the hanging ring 70 into the cabinet 2000.

[0057] In some embodiments, the heat insulation sheet 90 is detachably connected to the end of the fastener 80 away from the lifting ring 70, such that the projection of the heat insulation sheet 90 at least partially overlaps with the fastener 80 along the thickness direction of the support cover 10.

[0058] In some embodiments, such as Figure 4 and Figure 5 As shown, there are multiple heat insulation sheets 90, located on the side of the reinforcing rib 20 away from the support cover 10. The heat insulation sheets 90 are connected to the fixing member 80 via connectors. When the energy storage cabinet 1 is in a high-temperature external environment, external heat can be conducted to the fixing member 80 through the protective cover 60 and the support cover 10, as well as through the hanging ring 70 located on the protective cover 60. In this embodiment, by setting the heat insulation sheets 90 connected to the fixing member 80, the heat insulation sheets 90 can reduce the conduction of external heat from the fixing member 80 to the cabinet body, thereby reducing the overall heat transfer efficiency of the heat insulation cover 1000.

[0059] It is understood that the heat insulation sheet 90 is connected to the fastener 80 via a connector, which includes, but is not limited to, screws, rivets, magnets, or other connecting structures. In some embodiments, the heat insulation sheet 90 is a bakelite sheet.

[0060] In some embodiments, please refer to the following: Figure 8 The second insulation cotton 40 has an avoidance notch 401 located at its edge, and the insulation sheet 90 is located at the avoidance notch 401. The avoidance notch 401 allows the insulation sheet 90 to abut against the connecting column 3000 of the energy storage cabinet 1, facilitating a secure connection between the connecting column 3000 and the insulation sheet 90, reinforcing rib 20, and fastener 80. It also allows the insulation sheet 90 to better conform to the reinforcing rib 20 due to the support of the connecting column 3000, thereby reducing heat conduction through the reinforcing rib 20. Furthermore, the avoidance notch 401 provides installation space for the insulation sheet 90 and allows the second insulation cotton 40 to wrap around the connecting column 3000, further preventing heat transfer.

[0061] In some embodiments, the portion of the reinforcing rib 20 facing away from the first wall 10b has multiple connection positions (not shown), which are used to connect with the connecting column 3000 of the energy storage cabinet 1. Each connection position is provided with a heat insulation sheet 90. The heat insulation sheet 90 can reduce the conduction of external heat from the fastener 80 to the connecting column 3000. The heat insulation sheet 90 isolates the heat between the connecting column 3000 and the reinforcing rib 20, reducing the heat conduction from the reinforcing rib 20 to the connecting column 3000, thereby reducing the impact of external heat on the internal temperature of the cabinet 2000.

[0062] In this embodiment, a support cover 10, a reinforcing rib 20, a first heat insulation cotton 30, and a second heat insulation cotton 40 are provided. Along the thickness direction of the support cover 10, the support cover 10 has a first wall 10b and a second wall 10c arranged opposite to each other. The reinforcing rib 20 is located on the side of the first wall 10b away from the second wall 10c and is connected to the support cover 10. The first heat insulation cotton 30 is located on the side of the second wall 10c away from the reinforcing rib 20, and the second heat insulation cotton 40 is located on the side of the reinforcing rib 20 away from the support cover 10. The second heat insulation cotton 40 is detachably connected to the reinforcing rib 20, and a heat insulation cavity is provided between the second heat insulation cotton 40 and the support cover 10. The heat insulation cover 1000 is used to cover the energy storage cabinet 1. The first heat insulation cotton 30 can be used to prevent external heat from entering the support cover 10, forming a first layer of heat insulation protection. A heat insulation cavity 20a is provided between the second heat insulation cotton 40 and the support cover 10. Since air has a low thermal conductivity, the setting of the heat insulation cavity 20a can reduce the heat conduction towards the energy storage cabinet 1, forming a second layer of heat insulation protection. The second heat insulation cotton 40 is used to prevent external heat from entering the energy storage cabinet 1, forming a third layer of heat insulation protection. In this application, by setting multiple layers of heat insulation protection, the amount of external heat entering the energy storage cabinet 1 is reduced in the case of high external temperature environment.

[0063] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
