Description

Technical Field

[0001] This utility model belongs to the field of energy storage device technology, specifically relating to an energy storage module frame and an energy storage device. Background Technology

[0002] Currently, drawer-type devices are widely used in the assembly of energy storage cabinets and power cabinets. The conventional operating method for these devices is to pull them out directly from the front of the cabinet along the direction of the built-in handle to complete operations such as installation, maintenance, or replacement.

[0003] In some practical application scenarios, due to design limitations of energy storage cabinets or space constraints of the installation environment, the usable space inside the cabinet is often significantly insufficient, especially in the depth direction. Its dimensions are difficult to meet the normal pull-out requirements of drawer-type equipment. Even when the equipment is fully pulled out, it may not be able to operate smoothly due to the limited depth space, or even directly cause such equipment to be unsuitable for installation.

It should be understood that such data can be interchanged where appropriate so that embodiments of this utility model 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, the 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.

[0020] The embodiments of this utility model will be described in detail below with reference to the accompanying drawings, through specific examples and application scenarios.

[0021] This application provides an energy storage module rack, as shown in the following embodiment. Figure 1 , Figure 1 This is a schematic diagram of an energy storage module rack in an open state according to an embodiment of this application. The energy storage module rack includes a first rack 10 and a second rack 20. The first rack 10 includes two connecting beam units 101, a first support column 102, and a second support column 103. Each connecting beam unit 101 includes a first crossbeam 1011, a second crossbeam 1012, and a third crossbeam 1013. The first crossbeam 1011 and the second crossbeam 1012 are parallel to a first direction X, and are spaced apart along a second direction Y. The third crossbeam 1013 is parallel to the second direction Y, and both the first crossbeam 1011 and the second crossbeam 1012 are fixedly connected to the third crossbeam 1013. The length of the third crossbeam 1013 is greater than the distance between the first crossbeam 1011 and the second crossbeam 1012. Figure 2 , Figure 2This is another schematic diagram of an energy storage module rack in an open state provided in an embodiment of this application. The end of the third crossbeam 1013 connected to the first crossbeam 1011 is the first end 10131, and the end of the third crossbeam 1013 away from the first crossbeam 1011 is the second end 10132. Two connecting beam units 101 are spaced apart along the third direction Z. The first support column 102 and the second support column 103 are parallel to the third direction Z and located between the two connecting beam units 101. The first direction X, the second direction Y, and the third direction Z are mutually perpendicular. One end of the first support column 102 is fixedly connected to one connecting beam unit 101, and the other end of the first support column 102 is fixedly connected to another connecting beam unit 101. One end of the second support column 103 is fixedly connected to the second end 10132 of one third crossbeam 1013, and the other end of the second support column 103 is fixedly connected to the second end 10132 of another third crossbeam 1013. The second frame 20 is rotatably connected to the second support column 103.

[0022] The connecting beam unit 101 serves as the basic frame unit of the first frame 10. Each connecting beam unit 101 contains three crossbeams, which together form a local support structure. In the closed state, the first crossbeam 1011 extends along the first direction X, parallel to the second crossbeam 1012 and spaced apart in the second direction Y. It is one of the main lateral support components of the connecting beam unit 101, used to support and connect other structures. The second crossbeam 1012 also extends along the first direction X, cooperating with the first crossbeam 1011 to form a certain spacing in the second direction Y, providing a basic space for the installation and support of the energy storage module and enhancing the stability of the connecting beam unit 101. The third crossbeam 1013 extends along the second direction Y. The first crossbeam 1011 and the second crossbeam 1012 are respectively fixedly connected to the third crossbeam 1013, which serves to connect and reinforce the first two. Its length is greater than the distance between the first crossbeam 1011 and the second crossbeam 1012. The end connected to the first crossbeam 1011 is the first end 10131, and the end away from the first crossbeam 1011 is the second end 10132. The second end 10132 extends away from the first crossbeam 101, and the extended portion of the second end 10132 provides space for the connection of the second frame 20.

[0023] The first support column 102 extends along the third direction Z and is fixedly connected at both ends to two connecting beam units 101 that are spaced apart along the third direction Z, so that the two connecting beam units form a frame structure, which enhances the overall stability and structural strength of the first frame 10 in the third direction Z.

[0024] The second support column 103 extends along the third direction Z, and its two ends are fixedly connected to the second end 10132 of the third crossbeam 1013 in the two connecting beam units 101, which not only further strengthens the connection between the two connecting beam units 101, but also provides a support point for the installation of the second frame 20.

[0025] In the first rack 10, the side away from the third crossbeam 1013 is the first opening, through which energy storage modules and other equipment are installed into or removed from the energy storage module rack.

[0026] The length of the first crossbeam 1013 in the second direction Y is greater than the sum of the lengths of the first frame 10 and the second frame 20 in the second direction Y. When the second frame 20 rotates toward the first frame 10, that is, when the energy storage module frame is in the closed state, it is a cube.

[0027] The second frame 20 is a movable frame for installing energy storage components and can rotate around the second support column 103. The second frame 20 has a similar structure to the first frame 10, also being a frame structure composed of beams and columns. In the second frame 20, the side away from the third crossbeam 1013 is the second opening, through which energy storage modules and other equipment are installed into or removed from the energy storage module rack. The second frame 20 rotates around the second support column 103. When energy storage modules need to be installed into the second frame 20, it can be rotated away from the first frame 10; when installing or removing energy storage modules, it can be rotated towards the first frame 10. The first frame 10 and the second frame 20 are combined into a cuboid, which better meets the space-saving requirements of energy storage cabinets and other energy storage devices during daily use.

[0028] Furthermore, the second frame 20 is rotatably connected to the second support column 103, allowing the second frame 20 to be rotated to change the installation direction of the energy storage modules when there is insufficient internal space for equipment such as energy storage cabinets. The movable connection between the first frame 10 and the second frame 20 eliminates the operational obstruction caused by the dense stacking of equipment in traditional single-layer structures. Instead, operators can work on the equipment on the first frame 10 or the second frame 20 separately. In a limited space, when installing or maintaining energy storage modules, interference between different energy storage modules is reduced, significantly improving maintenance efficiency.

[0029] Traditional drawer-type devices are typically pulled out along the handle direction. If the depth along the second direction (Y) inside the cabinet is insufficient, the device often cannot be fully pulled out, making it difficult to access internal components during maintenance. This application addresses this by changing the installation direction of the inner device, creating a staggered pull-out path from the handle direction. This staggered design breaks the dependence on depth space, ensuring sufficient operating space after the inner device is pulled out, even within limited depth dimensions. This achieves both stable installation and convenient maintenance.

[0030] In addition, the lengths of the first crossbeam 1011, the second crossbeam 1012, and the third crossbeam 1013 can be adjusted according to the needs of different energy storage modules, so that the overall energy storage module rack can adapt to the installation of energy storage components of different specifications and sizes.

[0031] Optionally, the second support column 103 may also include a connecting column; the second frame 20 is rotatably connected to the connecting column.

[0032] The connecting column serves as a transition component between the second support column 103 and the second frame 20, and the position and height of the rotating connection point can be flexibly adjusted.

[0033] Secondly, this structure can reduce the processing complexity of the second support column 103. If the rotating connection structure is directly processed on the second support column 103, the processing difficulty or precision may be high due to the material and size limitations of the support column itself; while the connecting column can be manufactured separately using a material more suitable for the rotation requirements, and then fixed to the second support column 103, which not only ensures the rotation accuracy, but also simplifies the processing flow of the support column and reduces production costs.

[0034] The connecting column enhances the stability and durability of the rotating structure. When the second frame 20 rotates, the connecting part needs to withstand repeated friction and impact forces. The connecting column can be designed separately as a vulnerable part, for example, by using surface hardening treatment or built-in bearings to reduce the direct wear of the second support column 103. If rotation jamming or component damage occurs later, only the connecting column needs to be replaced, without the need to repair or replace the entire support column, thus reducing maintenance costs.

[0035] Optionally, refer to Figure 2 , Figure 2 This is another schematic diagram of an energy storage module rack in an open state, as provided in an embodiment of this application. Figure 2 The connecting beam unit 101 also includes a reinforcing beam 1014; the reinforcing beam 1014 is parallel to the second direction Y, and the two ends of the reinforcing beam 1014 are fixedly connected to a first crossbeam 1011 and a second crossbeam 1012, respectively.

[0036] Both the reinforcing beam 1014 and the third crossbeam 1013 are arranged along the second direction Y, that is, the reinforcing beam 1014 and the third crossbeam 1013 are parallel to each other, forming a double crossbeam connection structure. This is equivalent to adding a supporting rib between the first crossbeam 1011 and the second crossbeam 1012, which can effectively constrain the relative movement between the first crossbeam 1011 and the second crossbeam 1012, enhance the overall rigidity of the connecting beam unit 101 in the second direction Y, and avoid structural deformation caused by long-term load.

[0037] The reinforcing beam 1014 distributes the connecting force between the first crossbeam 1011 and the second crossbeam 1012 to the third crossbeam 1013 and the reinforcing beam 1014, reducing the load pressure on each crossbeam, extending the service life of the components, and reducing the maintenance frequency. Located between the first crossbeam 1011 and the second crossbeam 1012, the reinforcing beam 1014 directly supports the central area at the bottom of the module, preventing deformation caused by localized suspension, and reducing the pressure at the contact points between the module and the crossbeams, thus protecting the module casing and the frame crossbeams.

[0038] Optionally, refer to Figure 2 , Figure 2 This is another schematic diagram of an energy storage module rack in an open state, as provided in an embodiment of this application. Figure 2 The connecting beam unit 101 also includes a limiting plate 1015; along the second direction Y, the limiting plate 1015 can be detachably connected at different positions on the reinforcing beam 1014.

[0039] When energy storage modules are installed on the connecting beam unit 101, they may experience displacement along the first direction X or the second direction Y due to vibration, transportation, or impact during operation, leading to loose connections or component collisions. The limiting plate 1015 can be adjusted to contact the module from the side or end, forming a physical barrier and restricting the module's horizontal movement. Along the second direction Y, the limiting plate 1015 can be detachably connected at different positions on the reinforcing beam 1014, allowing the rack to accommodate energy storage modules of different sizes. For example, for small modules, the limiting plate 1015 can be installed close to the module; for large modules, the limiting plate 1015 can be pulled open to provide sufficient space, solving the problem that fixed limiting structures cannot accommodate multiple modules. When multiple energy storage modules are to be installed in a rack, the limiting plate 1015 can also serve to separate and position the multiple energy storage modules.

[0040] The detachable connection between the limiting plate 1015 and the reinforcing beam 1014 allows for quick release of constraints on the module. During installation, the limiting plate 1015 is removed or adjusted to a clearance position, allowing the energy storage module to be directly placed into the installation area. After installation, the limiting plate 1015 is reset to its designated position, securing the energy storage module. During disassembly, the limiting plate 1015 is readjusted to a clearance position, allowing the energy storage module to be directly removed. The entire process requires no tools for disassembly, significantly reducing loading and unloading time.

[0041] Optionally, refer to Figure 2 , Figure 2 This is another schematic diagram of an energy storage module rack in an open state, as provided in an embodiment of this application. Figure 2 The first frame 10 also includes a plurality of first connectors 104; the first connectors 104 are parallel to the third direction Z, one end of the first connector 104 is detachably connected to a second crossbeam 1012, and the other end is detachably connected to another second crossbeam 1012.

[0042] The first connector 104 fixes the two second crossbeams 1012 through a detachable connection. Its length can be selected or replaced according to actual needs. When the energy storage cabinet is deep, a longer first connector is selected to increase the distance between the two connecting beam units 101 and reserve sufficient space for large-capacity modules. When the height of the installation environment along the third direction Z is low, a shorter first connector 104 can be replaced to reduce the distance to adapt to the limited space.

[0043] Since the weight of the energy storage module not only exerts vertical pressure on the crossbeam, but may also generate thrust or tension in the second direction Y, it is equivalent to forming multiple longitudinal supports between the two connecting beam units 101. The first connector 104 can further fix and limit the energy storage module.

[0044] Furthermore, the first connector 104 is detachably connected to the second crossbeam 1012. When there is insufficient space in the first direction X for installing or disassembling the energy storage module, the first connector 104 can be removed, the energy storage module can be installed, and then the first connector 104 can be reinstalled to complete the installation of the energy storage module. When the energy storage module group needs maintenance, the first connector 104 can be removed, and the energy storage module can be taken out along the second direction Y, further improving the convenience and practicality of using the energy storage module rack.

[0045] Optionally, refer to Figure 2 , Figure 2 This is another schematic diagram of an energy storage module rack in an open state, as provided in an embodiment of this application. Figure 2 The energy storage module rack also includes at least one rubber pad 30; the rubber pad 30 is fixedly connected to the side of the first connector 104 facing the second rack 20.

[0046] When the second frame 20 rotates around the second support column 103, if it is opened during maintenance and closed during reset, its edges or sides may come into contact with the first connector 104. When the first connector 104, energy storage module, and second frame 20 are made of metal, direct collision may cause surface wear, coating peeling, or even structural deformation due to excessive impact. The rubber pad 30 is positioned facing the second frame 20. During rotation, the second frame 20 preferentially contacts the rubber pad 30. The elastic deformation of the rubber pad 30 absorbs the collision energy, converting hard impact into flexible buffering, avoiding direct friction or impact between metal parts, protecting the structural integrity of the first connector 104 and the second frame 20, and extending their service life.

[0047] Furthermore, if the rotation angle of the second frame 20 is too large, it may interfere with other components of the first frame 10, such as the second crossbeam 1012, or even pull on the connecting cables, causing cable breakage or loosening of the interface. The thickness and elasticity of the rubber pad 30 can form a physical limit. When the second frame 20 rotates to a preset angle, the rubber pad 30 will contact the second frame 20 before the metal part of the first connector 104, using the resistance generated by its own deformation to limit the rotation amplitude, indirectly controlling the maximum rotation angle of the second frame 20, and avoiding mechanical interference or cable damage caused by excessive rotation.

[0048] The rubber pad 30 not only protects the components of the energy storage module rack from collision damage, but also ensures structural stability through angle limitation and gap filling. At the same time, it optimizes the maintenance operation experience, making the rotation function of the energy storage module rack more reliable and durable.

[0049] Optionally, refer to Figure 3 , Figure 3 yes Figure 1 A schematic diagram of the energy storage module rack in the closed state. Figure 3 The first frame 10 also includes two second connectors 105; the second connectors 105 are parallel to the second direction Y, and the two ends of the second connectors 105 are fixedly connected to a first crossbeam 1011 and a second crossbeam 1012, respectively.

[0050] The second connector 105 extends along the second direction Y, and both ends of the second connector 105 are fixedly connected to a first crossbeam 1011 and a second crossbeam 1012, respectively. This makes the second connector 105, the first crossbeam 1011, the second crossbeam 1012 and the third crossbeam 1013 together form a more closed and stable three-dimensional frame. When the energy storage module is subjected to thrust in the first direction X, it can limit the displacement of the energy storage module, so that the energy storage module can be stably installed in the energy storage module rack.

[0051] Optionally, the second connector 105 is provided with a plurality of fixed nuts and / or movable nuts.

[0052] The energy storage module is fixed to the connecting beam unit 101 with fasteners such as bolts, making the installation of the energy storage module more stable.

[0053] When the second connector 105 is provided with multiple fixing nuts, the fixing nuts serve as preset standard connection points, which are suitable for modules with fixed mounting hole positions. No on-site drilling or tapping is required; the bolts are directly passed through the module and fastened to the nuts, simplifying the installation process.

[0054] When the second connector 105 is provided with multiple movable nuts, the movable nuts can slide along the second direction Y to adjust their position, adapting to modules with non-fixed mounting hole positions and solving the problem of misalignment of fixing points caused by differences in module size.

[0055] The rigid connection between the fixed nut and the second connector 105 ensures that it will not loosen under stress, making it suitable for bearing heavier components. The movable nut can slide as needed to accommodate the position of auxiliary components, such as adjusting the spacing of cable trays to fit cable bundles of different thicknesses, or moving the fixing points of the heat dissipation device to align with the heat-generating areas of the module, significantly improving the flexibility of functional expansion. When combined, the second connector 105 can accommodate the installation requirements of various modules, enhancing the versatility of the rack.

[0056] Optionally, refer to Figure 3 , Figure 3 yes Figure 1 A schematic diagram of the energy storage module rack in the closed state. Figure 3 The first frame 10 also includes a third connector 106; the third connector 106 is disposed on the side of the first crossbeam 1011 away from the third crossbeam 1013, the third connector 106 is parallel to the third direction Z, one end of the third connector 106 is fixedly connected to one first crossbeam 1011, and the other end is fixedly connected to another first crossbeam 1011.

[0057] The third connector 106 connects the edges of the two first crossbeams 1011 along the third direction Z, which is equivalent to forming a reinforcing beam on the outside of the frame, rigidly fixing the edges of the two first crossbeams 1011, dispersing the force in the edge area, avoiding deformation of the first crossbeams 1011 due to excessive local force, and enhancing the structural stability of the connecting beam unit 101 at the edge position.

[0058] Optionally, the cross-section of the plane formed by the third connector 106 along the first direction X and the second direction Y is "L" shaped.

[0059] The “L” shape is composed of two mutually perpendicular planes. Compared with a single flat plate, its cross-sectional moment of inertia is larger. When subjected to lateral or vertical forces, the two perpendicular planes can work together to disperse stress, effectively resisting bending and torsion. It is more suitable as a load-bearing structure on the outer edge of the frame, stably supporting external components or coping with external forces such as collisions and installation thrust, and avoiding deformation of the edge due to force concentration.

[0060] The right-angle structure facilitates positioning and alignment during assembly. The facade along the first direction X can be aligned with the side of the first crossbeam 1011 away from the second crossbeam 1012; the inside along the second direction Y can be aligned with the side of the first crossbeam 1011 away from the third crossbeam 1013. The right-angle structure formed by the two facades of the third connector 106 facilitates positioning and alignment during assembly, reduces calibration steps, and improves installation efficiency.

[0061] Optionally, refer to Figure 4 , Figure 4 yes Figure 1 Another schematic diagram of the energy storage module rack in the closed state. Figure 4 In the second frame 20, there are: a body 201 and a cover plate 202; the body 201 has an opening, and the cover plate 202 is detachably connected to the body 201 at the opening.

[0062] The detachable design of the main body 201 and cover plate 202 in the second rack 20 provides a precise and convenient operating path for equipment maintenance. The opening on the main body 201 matches the shape and size of the cover plate 202, allowing the cover plate 202 to precisely cover the opening area. Normally, it forms a complete structure with the main body 201, protecting the internal equipment from dust and foreign objects. When maintenance is required on the energy storage module on the second rack 20, it is not necessary to disassemble the entire second rack 20. Simply remove the cover plate 202 from the opening to directly access the corresponding equipment area for quick wiring checks, component replacement, and other operations. This design avoids the cumbersome process of disassembling the entire rack in traditional maintenance. Especially when the installation space of the second rack 20 is narrow or adjacent to other structures, it can minimize the occupation of operating space, significantly improve maintenance efficiency, and reduce the risk of equipment damage caused by large-scale disassembly.

[0063] Secondly, refer to Figure 5 and Figure 6 , Figure 5 and Figure 6 This is a schematic diagram of an energy storage module rack provided in an embodiment of this application, in which energy storage modules are mounted. This application also provides an energy storage device, which includes multiple energy storage modules 100 and an energy storage module rack as described above, wherein the energy storage modules 100 are mounted in the energy storage module rack.

[0064] Applying the aforementioned energy storage module rack to energy storage equipment allows for changes in the installation and removal orientation of the energy storage modules 100 within the rack, especially when internal space is limited. This improves the convenience and efficiency of installing or maintaining the energy storage modules 100 within a confined space, thereby enhancing the space utilization of the energy storage equipment.

[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
