Energy storage box and energy storage container

[0001] This application claims priority to Chinese Patent Application No. 202422116201.X, filed with the Chinese Patent Office on August 29, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of energy storage box technology, specifically to an energy storage box body and an energy storage box. Background Technology

[0003] With the improvement of energy storage systems and the needs of economic development, the lithium battery chemistry-based power energy storage system industry is developing rapidly. The demand for charging and discharging of energy storage systems with large cells, high rate of operation, and high density integration is increasing. As the charging and discharging current increases, the size and weight of each electrical component are also increasing accordingly. Invention Overview

[0004] In related technologies, electrical components are installed at the bottom of the energy storage box. Due to the large weight of each electrical component, the base plate is subjected to a large force, which may lead to large deformation of the base plate, thereby affecting the stability and applicability of the electrical components and reducing the reliability of the energy storage system.

[0005] Therefore, there is an urgent need to design an energy storage box and energy storage container to solve the technical risks.

[0006] In a first aspect, this application provides an energy storage box, which includes: a base plate; a plurality of first side plates surrounding the periphery of the base plate, the plurality of first side plates and the base plate together forming a receiving cavity for accommodating electrical components; a receiving member disposed within the receiving cavity, one side of the receiving member being fixedly connected to the base plate, and the other side of the receiving member being used to install electrical components; and a plurality of connecting members disposed on the base plate, the receiving member being connected to the base plate via the connecting members.

[0007] Secondly, this application provides an energy storage box, which includes the aforementioned energy storage box body, the energy storage box body having a receiving cavity; electrical components are disposed within the receiving cavity. Beneficial effects

[0008] The energy storage tank provided in this application has a supporting member installed inside the energy storage tank. One side of the supporting member is used for fixed connection with the bottom plate of the energy storage tank, and the other side of the supporting member is used for installing electrical components. This can avoid direct contact between the heavy electrical components and the bottom plate of the energy storage tank, which would cause deformation of the bottom plate. At the same time, multiple connectors are installed on the bottom plate, and the supporting member is connected to the bottom plate through the connectors. This can distribute the force of the supporting member on the bottom plate through multiple connectors, making the stress on the bottom plate more even, thereby protecting the bottom plate structure of the energy storage tank and extending the service life of the bottom plate.

[0009] The energy storage box provided in this application uses the aforementioned energy storage box body, which improves the service life of the energy storage box. Attached Figure Description

[0023] As shown in Figures 1-5, in a first aspect, embodiments of this application provide an energy storage box, which includes: a base plate 10; a plurality of first side plates 20 surrounding the periphery of the base plate 10, the plurality of first side plates 20 and the base plate 10 together forming a receiving cavity 11 for accommodating electrical components 50; a receiving member 30 disposed within the receiving cavity 11, one side of the receiving member 30 being fixedly connected to the base plate 10, and the other side of the receiving member 30 being used to install the electrical components 50; and a plurality of connecting members 40 disposed on the base plate 10, the receiving member 30 being connected to the base plate 10 via the connecting members 40.

[0024] In a first aspect, embodiments of this application provide an energy storage box, which includes: a base plate 10; a plurality of first side plates 20 surrounding the periphery of the base plate 10, the plurality of first side plates 20 and the base plate 10 together forming a receiving cavity 11, the receiving cavity 11 being used to receive electrical components 50; a receiving member 30 disposed within the receiving cavity 11, one side of the receiving member 30 being used for fixed connection with the base plate 10, and the other side of the receiving member 30 being used for mounting electrical components 50; and a plurality of connecting members 40 distributed on the side of the base plate 10 facing the receiving cavity 11, the receiving member 30 being connected to the base plate 10 via the connecting members 40.

[0025] By applying the technical solution of this application, a support member 30 is provided inside the energy storage box. One side of the support member 30 is used to fix and connect to the bottom plate 10 of the energy storage box, and the other side of the support member 30 is used to install electrical components 50. This can avoid the heavy electrical components 50 from directly contacting the bottom plate 10 of the energy storage box, which would cause the bottom plate 10 of the energy storage box to deform. At the same time, multiple connectors 40 are provided on the bottom plate 10. The support member 30 is connected to the bottom plate 10 through the connectors 40. This can disperse the force of the support member 30 on the bottom plate 10 through the multiple connectors 40, making the stress on the bottom plate 10 more uniform, thereby protecting the structure of the bottom plate 10 of the energy storage box and extending the service life of the bottom plate 10.

[0026] In one embodiment, multiple connectors 40 are arranged in an array on the base plate 10. This arrangement makes the distribution of connectors 40 more uniform, thereby further dispersing the load on the base plate 10 and protecting the structure of the base plate 10. This not only helps to extend the service life of the base plate 10, but also ensures the stability of the electrical components during operation.

[0027] In one embodiment, the distance between two adjacent connectors 40 along the length of the base plate 10 is L1, where 600mm ≤ L1 ≤ 656mm. When L1 > 656mm, the distance between two adjacent connectors 40 along the length of the base plate 10 is too large. Since the length of the base plate 10 is limited, this not only reduces the number of connectors 40 but also hinders the connection of the receiving component 30. When L1 < 600mm, the distance between two adjacent connectors 40 along the length of the base plate 10 is too small, which increases the number of connectors 40 and is detrimental to the production cost of the energy storage box. Therefore, setting 600mm ≤ L1 ≤ 656mm not only ensures the number of connectors 40 is sufficient for connecting the receiving component 30 but also prevents an excessive number of connectors 40, thus controlling the production cost of the energy storage box and enabling mass production of the energy storage box. Optionally, L1 can be set to values ​​such as 600mm, 630mm, or 656mm. There are no specific restrictions here, and the specific setting should be selected according to the usage environment of the device.

[0028] In one embodiment, the interval between two adjacent connectors 40 along the width direction of the base plate 10 is L2, where 400mm ≤ L2 ≤ 457mm. When L2 > 457mm, the interval between two adjacent connectors 40 along the width direction of the base plate 10 is too large. Since the width of the base plate 10 is limited, this not only reduces the number of connectors 40 but also makes it difficult to connect the receiving parts 30. When L2 < 400mm, the interval between two adjacent connectors 40 along the width direction of the base plate 10 is too small, which increases the number of connectors 40 and is detrimental to the production cost of the energy storage box. Therefore, setting 400mm ≤ L2 ≤ 457mm not only ensures the number of connectors 40 is sufficient for connecting the receiving parts 30 but also prevents an excessive number of connectors 40, thus controlling the production cost of the energy storage box and enabling mass production of the energy storage box. Optionally, L2 can be set to values ​​such as 400mm, 500mm, or 457mm. There are no specific restrictions here, and the specific setting should be selected according to the usage environment of the device.

[0029] In one embodiment, the extending directions of the plurality of connectors 40 form an angle with the length direction or width direction of the base plate 10. This arrangement allows the energy storage enclosure to meet the usage requirements of different environments, thereby improving the applicability and scope of use of the energy storage enclosure. Optionally, the angle between the extending directions of the plurality of connectors 40 and the length direction or width direction of the base plate 10 can be 45°, 60°, or 90°, etc., and the specific arrangement should be selected according to the usage environment of the device.

[0030] In one embodiment, the multiple connectors 40 located in the middle of the base plate 10 extend in different directions than the multiple connectors 40 located along the edges of the base plate 10. This arrangement enables the energy storage enclosure to meet the usage requirements in different environments, thereby further improving the applicability and scope of use of the energy storage enclosure.

[0031] In one embodiment, a plurality of connectors 40 located in the middle of the base plate 10 extend along the length direction of the base plate 10, and a plurality of connectors 40 located in the middle of the base plate 10 extend along the width direction of the base plate 10. This arrangement facilitates the installation of the connectors 40, and also makes the stress on the base plate 10 more even, reducing the possibility of mechanical damage to the base plate 10, and improving the reliability of the installation of electrical components 50.

[0032] In one embodiment, a plurality of connectors 40 located in the middle of the base plate 10 extend along the width direction of the base plate 10, and a plurality of connectors 40 located in the middle of the base plate 10 extend along the length direction of the base plate 10. This arrangement facilitates the installation of the connectors 40, and also makes the stress on the base plate 10 more even, reducing the possibility of mechanical damage to the base plate 10, and improving the reliability of the installation of electrical components 50.

[0033] In one embodiment, the plurality of connectors 40 located in the middle of the base plate 10 extend in the same direction as the plurality of connectors 40 located along the edges of the base plate 10. This arrangement enables the energy storage enclosure to meet the usage requirements of different environments, thereby further improving the applicability and scope of use of the energy storage enclosure.

[0034] In one embodiment, the connector 40 includes a first connecting structure 41, a second connecting structure 42, and a third connecting structure 43 connected sequentially and arranged at an included angle. The first connecting structure 41 and the third connecting structure 43 are located on the same side of the second connecting structure 42. The first connecting structure 41 and the third connecting structure 43 are used to connect to the base plate 10, and the second connecting structure 42 is used to connect to the receiving component 30. In this application, the second connecting structure 42 protrudes from the first connecting structure 41 and the third connecting structure 43 on the side away from the base plate 10. By setting the above structure, the connection strength when the receiving component 30 is connected to the base plate 10 can be improved, thereby improving the safety of the electrical component 50 during use.

[0035] In one embodiment, the receiving member 30 includes: a receiving plate 31 having a first side and a second side disposed opposite to each other, the first side being used to connect with the second connecting structure 42, and the second side being used to mount electrical components 50; and a plurality of second side plates 32 surrounding the periphery of the receiving plate 31, the second side plates 32 extending toward the base plate 10. This arrangement can improve the structural strength of the receiving member 30, thereby extending the service life of the receiving member 30.

[0036] In one embodiment, the extension length of the second side plate 32 is less than or equal to the height of the second connecting structure 42 protruding from the first connecting structure 41. With this configuration, when the extension length of the second side plate 32 is equal to the height of the second connecting structure 42 protruding from the first connecting structure 41, the base plate 10 can bear the weight of the second side plate 32, thereby further improving the uniformity of stress distribution on the base plate 10 to meet the load-bearing requirements of the electrical component 50.

[0037] In one embodiment, the connector 40 is bolted to the base plate 10 and / or the connector 40 is bolted to the receiving member 30. Bolted connections are particularly suitable for applications requiring high strength and high loads. This connection method ensures a stable connection even under extreme conditions, thereby guaranteeing the safety and stability of the overall structure. Furthermore, the bolts are detachable, allowing for easy disassembly for maintenance, component replacement, or structural adjustments, significantly saving time and labor costs.

[0038] In one embodiment, the cross-sectional area of ​​the receiving component 30 is less than or equal to the cross-sectional area of ​​the base plate 10. This arrangement facilitates the installation and disassembly of the receiving component 30, thereby improving the efficiency of maintenance and replacement of the receiving component 30.

[0039] Secondly, embodiments of this application provide an energy storage box, which includes the aforementioned energy storage box body, the energy storage box body having a receiving cavity 11; and electrical components 50 disposed within the receiving cavity 11.

[0040] By applying the technical solution of this application, a support member 30 is provided inside the energy storage box. One side of the support member 30 is used to fix and connect to the bottom plate 10 of the energy storage box, and the other side of the support member 30 is used to install electrical components 50. This can avoid the heavy electrical components 50 from directly contacting the bottom plate 10 of the energy storage box, which would cause the bottom plate 10 of the energy storage box to deform. At the same time, multiple connectors 40 are provided on the bottom plate 10. The support member 30 is connected to the bottom plate 10 through the connectors 40. This can disperse the force of the support member 30 on the bottom plate 10 through the multiple connectors 40, making the stress on the bottom plate 10 more uniform, thereby protecting the structure of the bottom plate 10 of the energy storage box and extending the service life of the bottom plate 10.
