[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0034] like Figure 1-Figure 5As shown, in the first aspect, an embodiment of the present invention provides an energy storage device, which includes: a base plate 10; a plurality of first side plates 20, which are arranged around the periphery of the base plate 10, and the plurality of first side plates 20 and the base plate 10 together form a accommodating cavity 11, and the accommodating cavity 11 is used to accommodate electrical components 50; a socket 30, which is arranged in the accommodating cavity 11, and one side of the socket 30 is used to be fixedly connected to the base plate 10, and the other side of the socket 30 is used to install the electrical components 50; a plurality of connecting members 40, which are arranged on the base plate 10, and the socket 30 and the base plate 10 are connected via the connecting members 40.

[0035] In the first aspect, an embodiment of the present invention provides an energy storage device, which includes: a base plate 10; a plurality of first side plates 20, which are arranged around the periphery of the base plate 10, and the plurality of first side plates 20 and the base plate 10 together form a accommodating cavity 11, and the accommodating cavity 11 is used to accommodate electrical components 50; a socket 30, which is arranged in the accommodating cavity 11, and one side of the socket 30 is used to be fixedly connected to the base plate 10, and the other side of the socket 30 is used to install the electrical components 50; a plurality of connecting members 40, which are distributed on the side of the base plate 10 facing the accommodating cavity 11, and the socket 30 and the base plate 10 are connected via the connecting member 40.

[0036] By applying the technical solution of the present invention, a receiving member 30 is provided in the energy storage, and one side of the receiving member 30 is used for fixed connection with the bottom plate 10 of the energy storage, and the other side of the receiving member 30 is used for installing the electrical component 50. This can avoid direct contact between the overweight electrical component 50 and the bottom plate 10 of the energy storage, which may cause deformation of the bottom plate 10 of the energy storage. At the same time, a plurality of connecting members 40 are provided on the bottom plate 10, and the receiving member 30 and the bottom plate 10 are connected by the connecting member 40. In this way, the force exerted by the receiving member 30 on the bottom plate 10 can be dispersed through the plurality of connecting members 40, so that the force on the bottom plate 10 is more uniform, thereby protecting the structure of the bottom plate 10 of the energy storage and extending the service life of the bottom plate 10.

[0037] In one embodiment, a plurality of connectors 40 are arranged in an array on the base plate 10. This arrangement makes the distribution of the connectors 40 more uniform, thereby further dispersing the bearing force of the base plate 10 and further 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.

[0038] In one embodiment, the spacing between two adjacent connectors 40 along the length direction of the bottom plate 10 is L1, 600mm≤L1≤656mm. When L1>656mm, the spacing between two adjacent connectors 40 along the length direction of the bottom plate 10 is too large. Since the length of the bottom plate 10 is limited, this not only reduces the number of connectors 40 provided, but is also not conducive to connecting the receiving member 30. When L1<600mm, the spacing between two adjacent connectors 40 along the length direction of the bottom plate 10 is too small, which increases the number of connectors 40 provided, which is not conducive to the production cost of energy storage. Therefore, setting 600mm≤L1≤656mm can not only ensure the number of connectors 40 provided, which is conducive to connecting the receiving member 30, but also prevent the number of connectors 40 provided from being excessive, which is conducive to controlling the production cost of energy storage and realizing mass production of energy storage. Optionally, L1 can be set to values ​​such as 600 mm, 630 mm or 656 mm, without any specific limitation herein. The specific setting should be selected according to the use environment of the device.

[0039] In one embodiment, the spacing between two adjacent connectors 40 along the width direction of the bottom plate 10 is L2, 400mm≤L2≤457mm. When L2>457mm, the spacing between two adjacent connectors 40 along the width direction of the bottom plate 10 is too large. Since the width of the bottom plate 10 is limited, this not only reduces the number of connectors 40 provided, but is also not conducive to connecting the receiving member 30. When L2<400mm, the spacing between two adjacent connectors 40 along the width direction of the bottom plate 10 is too small, which increases the number of connectors 40 provided, which is not conducive to the production cost of energy storage. Therefore, setting 400mm≤L2≤457mm can not only ensure the number of connectors 40 provided, which is conducive to connecting the receiving member 30, but also prevent the number of connectors 40 provided from being excessive, which is conducive to controlling the production cost of energy storage and realizing mass production of energy storage. Optionally, L2 can be set to values ​​such as 400 mm, 500 mm or 457 mm, without any specific limitation herein. The specific setting should be selected according to the use environment of the device.

[0040] In one embodiment, the extension direction of the multiple connectors 40 forms an angle with the length direction or width direction of the base plate 10. This arrangement enables the energy storage to meet the needs of different environments, thereby improving the applicability and scope of application of the energy storage. Optionally, the angle between the extension direction of the multiple connectors 40 and the length direction or width direction of the base plate 10 can be 45°, 60°, or 90°, etc. The specific setting should be selected according to the environment in which the device is used.

[0041] 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 at the edge of the base plate 10. This arrangement enables the energy storage to meet the needs of use in different environments, thereby further improving the applicability and scope of application of the energy storage.

[0042] In one embodiment, the plurality of connectors 40 located in the middle of the base plate 10 extend along the length of the base plate 10, and the plurality of connectors 40 located in the middle of the base plate 10 extend along the width of the base plate 10. This arrangement facilitates the installation of the connectors 40 and also makes the force applied to the base plate 10 more uniform, thereby reducing the possibility of mechanical damage to the base plate 10 and improving the reliability of the installation of the electrical components 50.

[0043] In one embodiment, the plurality of connectors 40 located in the middle of the base plate 10 extend along the width direction of the base plate 10, and the 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 force applied to the base plate 10 more uniform, thereby reducing the possibility of mechanical damage to the base plate 10 and improving the reliability of the installation of the electrical components 50.

[0044] In one embodiment, the multiple connectors 40 located in the middle of the bottom plate 10 extend in the same direction as the multiple connectors 40 located at the edge of the bottom plate 10. This arrangement enables the energy storage to meet the needs of use in different environments, thereby further improving the applicability and scope of application of the energy storage.

[0045] In one embodiment, the connector 40 includes a first connecting structure 41, a second connecting structure 42, and a third connecting structure 43, which are sequentially connected and arranged at an 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, while the second connecting structure 42 is used to connect to the receiving member 30. In this application, the second connecting structure 42 is arranged to protrude from the first connecting structure 41 and the third connecting structure 43 on the side away from the base plate 10. This configuration improves the connection strength between the receiving member 30 and the base plate 10, thereby enhancing the safety of the electrical component 50 during use.

[0046] In one embodiment, the receiving member 30 includes a receiving plate 31 having a first side and a second side disposed opposite each other, the first side being configured to connect to the second connecting structure 42 and the second side being configured to mount the electrical component 50; and a plurality of second side panels 32 disposed around the periphery of the receiving plate 31, the second side panels 32 extending toward the base plate 10. This arrangement enhances the structural strength of the receiving member 30, thereby extending its service life.

[0047] In one embodiment, the extended length of the second side plate 32 is less than or equal to the height by which the second connecting structure 42 protrudes from the first connecting structure 41. With this configuration, when the extended length of the second side plate 32 is equal to the height by which the second connecting structure 42 protrudes from the first connecting structure 41, the bottom plate 10 can bear the weight of the second side plate 32, thereby further improving the uniformity of the force applied to the bottom plate 10 and meeting the load-bearing requirements of the electrical components 50.

[0048] In one embodiment, the connector 40 is connected to the base plate 10 and / or to the receiving member 30 by bolts. Bolted connections are particularly suitable for applications requiring high strength and loads. This connection ensures a stable connection even under extreme operating conditions, thereby safeguarding the safety and stability of the overall structure. Furthermore, the bolts are removable, allowing for easy removal and reassembly for repairs, component replacement, or structural adjustments, significantly saving time and labor costs.

[0049] In one embodiment, the cross-sectional area of ​​the receiving member 30 is less than or equal to the cross-sectional area of ​​the bottom plate 10. This configuration facilitates installation and removal of the receiving member 30, thereby improving the efficiency of maintenance and replacement of the receiving member 30.

[0050] In a second aspect, an embodiment of the present invention provides an energy storage box, which includes the above-mentioned energy storage, and the energy storage has a receiving cavity 11; an electrical component 50 is arranged in the receiving cavity 11.

[0051] By applying the technical solution of the present invention, a receiving member 30 is provided in the energy storage, and one side of the receiving member 30 is used for fixed connection with the bottom plate 10 of the energy storage, and the other side of the receiving member 30 is used for installing the electrical component 50. This can avoid direct contact between the overweight electrical component 50 and the bottom plate 10 of the energy storage, which may cause deformation of the bottom plate 10 of the energy storage. At the same time, a plurality of connecting members 40 are provided on the bottom plate 10, and the receiving member 30 and the bottom plate 10 are connected by the connecting member 40. In this way, the force exerted by the receiving member 30 on the bottom plate 10 can be dispersed through the plurality of connecting members 40, so that the force on the bottom plate 10 is more uniform, thereby protecting the structure of the bottom plate 10 of the energy storage and extending the service life of the bottom plate 10.
