Description

Technical Field

[0001] The utility model relates to the field of energy storage containers, in particular to a battery rack and an energy storage container. Background Art

[0002] An energy storage container is an integrated energy storage system that integrates multiple energy storage and energy management devices. Its core components usually include energy storage batteries, battery management systems (BMS), energy conversion systems (such as power electronic converters), container dynamic environment monitoring systems, etc. These devices are encapsulated in a standardized container to form a complete and independent energy storage unit.

[0003] Inside the energy storage container, the battery rack is designed to tightly arrange and secure multiple battery modules. It provides stable support and fixation for the battery pack, promotes heat dissipation, facilitates the arrangement and connection of battery modules, ensures the safety of the battery pack, and simplifies the maintenance and management of the battery pack. At the same time, the battery rack is usually customized according to the size and shape of the battery and is made of metal materials such as iron and aluminum to ensure its strength and stability.

[0004] Regarding the above-mentioned related technologies, the inventors found that as the batteries age and are damaged, they need to be maintained and replaced regularly. However, battery modules are often firmly mounted on battery racks with fasteners such as bolts. This design is particularly inconvenient during maintenance, which not only increases the difficulty of disassembly and assembly for staff, but also directly leads to an increase in maintenance costs. At the same time, a large amount of heat energy will be generated during the battery charge and discharge cycle, and the battery rack layout in traditional energy storage containers often makes the distance between battery modules too close, which seriously hinders the effective dissipation of heat, thereby posing a threat to the performance and life of the battery, and may even cause safety hazards. Utility Model Content

[0005] The main technical problem solved by the utility model is to provide a battery rack and an energy storage container, which are convenient for disassembly and assembly of battery modules and improve the convenience of maintenance and replacement of battery modules.

[0006] In order to solve the above technical problems, a technical solution adopted by the present invention is:

[0007] In a first aspect, a battery rack is provided, comprising: two symmetrically arranged support frame assemblies, wherein a plurality of support assemblies are spaced apart and connected therebetween, cross bars are symmetrically connected to the top and bottom of the support frame assemblies, and battery pack assemblies are detachably connected to the support assemblies;

[0008] The supporting assembly includes a concave-convex plate and a symmetrically arranged limit guide shell, and the opposite sides of two adjacent concave-convex plates are respectively connected to the limit guide shell, and the top and bottom of the inner cavity of the limit guide shell are respectively provided with a limit slot;

[0009] The battery pack assembly includes a battery pack body and limit bars connected to both sides of the top and bottom of the battery pack body, respectively. The limit bars are slidably connected to corresponding limit slots. An end cover plate is connected to one side of the battery pack body, and through holes are respectively formed at both ends of the end cover plate.

[0010] One side of the support frame assembly is respectively provided with a limiting notch that matches the battery pack assembly, and the limiting notch is respectively connected to a limiting screw, and the limiting screw is respectively passed through the through hole and threadedly connected with a butterfly bolt, and the butterfly bolt is respectively connected to the end cover plate.

[0011] By adopting the above technical solution, the supporting assembly provides a stable support platform for the battery pack assembly, while allowing appropriate spacing between battery packs to facilitate heat dissipation and maintenance. The concave and convex plates and the limiting slots form a stable support and guide structure, ensuring that the battery pack assembly can be accurately aligned during installation, preventing installation difficulties or damage due to misalignment. At the same time, the limiting strips and limiting slots enable rapid installation and disassembly of the battery pack assembly on the supporting assembly, thereby improving the convenience and efficiency of maintenance. The limiting screw achieves the final fixation of the battery pack assembly on the support frame assembly. At the same time, the design of the butterfly bolt facilitates quick tightening and loosening, thereby improving the flexibility of maintenance.

[0012] In a preferred example, the present invention can be further configured as follows: the concave-convex plate member includes a concave-convex plate, the top of the concave-convex plate is formed with no less than two upper plane protrusions, the bottom of the concave-convex plate is formed with no less than two lower plane protrusions, the concave-convex plate is provided with a plurality of hollow grooves spaced apart from each other, the upper plane protrusions are provided with mounting openings, a roller is rotatably connected in the mounting opening, and the roller is in rolling contact with the bottom of the battery pack body.

[0013] By adopting the above technical solution, the upper plane protrusions and the lower plane protrusions increase the surface area of ​​the concave-convex plate, and the inner cavity also forms an air flow cavity, which helps to improve the heat dissipation effect. At the same time, it also provides additional support points, enhances the carrying capacity and stability of the concave-convex plate, and the hollow groove further promotes the circulation and dissipation of heat, reducing the accumulation of heat on the concave-convex plate. The roller realizes rolling contact between the battery pack body and the concave-convex plate, rather than traditional sliding or fixed contact. This rolling contact method reduces the friction resistance of the battery pack during installation, disassembly or maintenance, making the operation smoother and more labor-saving.

[0014] In a preferred example, the present invention can be further configured as follows: the top of the battery pack body is spaced apart with limiting grooves adapted to the lower plane protrusions, and the bottom end of the lower plane protrusion is located in the limiting groove and is slidably connected thereto.

[0015] By adopting the above technical solution, the design of the limiting groove and the lower plane protrusion realizes the precise positioning of the battery pack body on the supporting assembly. When the battery pack assembly is placed on the supporting assembly, the lower plane protrusion will naturally slide into the corresponding limiting groove, ensuring that the battery pack body is in the correct installation position. This sliding connection method not only improves the accuracy and efficiency of installation, but also enhances the stability of the battery pack assembly on the supporting assembly, preventing displacement or loosening due to vibration or external force.

[0016] In a preferred example, the present invention can be further configured as follows: the two ends of the top of the inner cavity of the limiting guide shell are respectively connected with elastic arc-shaped snap buckles, and waist-shaped openings are opened at both ends of the elastic arc-shaped snap buckles. Screws connected to the limiting guide shell are provided in the waist-shaped openings, and the screws are respectively set far apart, and arc-shaped snap-in openings adapted to the elastic arc-shaped snap buckles are spaced apart on the upper surface of the limiting strip at the top.

[0017] By adopting the above technical solution, the cooperation between the elastic arc-shaped snap buckle and the arc-shaped snap mouth further limits the installation of the battery pack assembly, and during the disassembly and assembly process, the elastic arc-shaped snap buckle undergoes elastic deformation. Since waist-shaped openings are provided at both ends of the elastic arc-shaped snap buckle, a space is provided for the deformation of the elastic arc-shaped snap buckle, thereby allowing the battery pack assembly and the supporting assembly to be disassembled and separated.

[0018] In a preferred example, the present invention can be further configured as follows: a side of the position-limiting guide shell close to the end cover plate is an inclined surface, and the length of the bottom of the position-limiting guide shell is greater than the length of the top thereof.

[0019] By adopting the above technical solution, the inclined surface design plays a guiding and positioning role during the installation of the battery pack assembly. When the battery pack assembly is placed on the supporting assembly, the inclined surface can naturally guide the battery pack assembly to slide to the correct position, reducing the difficulty of alignment during installation. At the same time, the inclined surface also helps the battery pack assembly maintain a stable posture when subjected to external force, preventing it from deviating from the installation position.

[0020] In a preferred example, the present invention can be further configured as follows: the support frame assembly includes symmetrically arranged columns, a plurality of connecting rods are connected between the columns, and the connecting rods are connected to the concave and convex plate members.

[0021] By adopting the above technical solution, the support frame assembly provides a solid load-bearing and support platform for the battery pack or other equipment through a combination of columns and connecting rods, enabling it to withstand greater weight and impact force, ensuring the stability of the equipment during transportation, installation and use.

[0022] On the other hand, the energy storage container includes a box body and a plurality of battery racks arranged in the box body, and the surface of the box body is provided with ventilation holes.

[0023] By adopting the above technical solution, the vents introduce external airflow into the box, forming an effective air circulation path.

[0024] In summary, the present invention includes at least the following beneficial technical effects of the battery rack and energy storage container:

[0025] 1. The concave and convex plates and the limiting card slots form a stable support and guide structure, so that the battery pack assembly can be accurately aligned during installation, preventing installation difficulties or damage caused by misalignment. At the same time, the limiting strips and limiting card slots enable the battery pack assembly to be quickly installed and disassembled on the supporting assembly, improving the convenience and efficiency of maintenance. The battery pack assembly is fixed with the cooperation of the limiting screw and butterfly bolt.

[0026] 2. The concave-convex plate and the limit slot form a stable support and guide structure, and the roller is used to achieve rolling contact between the battery pack body and the concave-convex plate, which reduces the friction resistance of the battery pack during installation, removal or maintenance, making the operation smoother and more labor-saving. The upper and lower plane convexities increase the surface area of ​​the concave-convex plate, and the inner cavity also forms an air flow cavity, which helps to improve the heat dissipation effect. At the same time, it also provides additional support points, enhancing the bearing capacity and stability of the concave-convex plate.

[0027] 3. The raised upper and lower surfaces allow the heat generated by the battery during charging and discharging to be quickly and effectively discharged out of the box through air circulation, avoiding the negative impact of heat accumulation on battery performance and life. At the same time, the optimized heat dissipation performance also helps maintain a suitable temperature environment inside the box, further improving the battery's operating efficiency and safety, and providing a strong guarantee for the stable operation of the energy storage system.

[0040] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0041] It should be noted that these drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0042] Example 1, with reference to Figure 1-5The utility model provides a battery rack, comprising: two symmetrically arranged support frame assemblies 10, a plurality of support assemblies 20 are connected between the support frame assemblies 10, the top and bottom of the support frame assembly 10 are symmetrically connected with cross bars 3, the support assemblies 20 are detachably connected with battery pack assemblies 40, the support assemblies 20 include concave and convex plates 21 and symmetrically arranged limit guide shells 22, the opposite sides of two adjacent concave and convex plates 21 are respectively connected to the limit guide shells 22, and the top and bottom of the inner cavity of the limit guide shell 22 are respectively provided with limit slots 23, the support frame assembly 10 includes symmetrically arranged columns 11, a plurality of connecting rods 12 are connected between the columns 11, and the connecting rods 12 are connected to the concave and convex plates 21 The battery pack assembly 40 includes a battery pack body 41 and limiting bars 42 respectively connected to the top and bottom sides thereof, the limiting bars 42 are respectively slidably connected to the corresponding limiting slots 23, and an end cover plate 43 is connected to one side of the battery pack body 41. Through holes 44 are respectively opened at both ends of the end cover plate 43. Limiting notches 5 matching the battery pack assembly 40 are respectively opened on one side of the support frame assembly 10, and limiting screws 6 are respectively connected in the limiting notches 5. The limiting screws 6 are respectively inserted into the through holes 44 and threadedly connected with butterfly bolts 7. The butterfly bolts 7 are respectively connected to the end cover plates 43. The side of the limiting guide shell 22 close to the end cover plate 43 is an inclined surface, and the length of the bottom of the limiting guide shell 22 is greater than the length of its top.

[0043] Furthermore, the surface of the end cover plate 43 is symmetrically connected with a handle so that the staff can disassemble and assemble the battery pack body 41. The support frame assembly 10 provides a solid load-bearing and support platform for the battery pack assembly 40 or other equipment through the combination of the column 11 and the connecting rod 12. It can withstand large weight and impact force, ensure the stability of the equipment during transportation, installation and use, and enhance the connection strength between the columns 11 under the action of the cross bar 3, making the entire support frame assembly 10 more stable, ensuring that it is not easy to deform or overturn when bearing the weight of the battery pack assembly 40 and external forces. The concave and convex plate 21 and the limit guide shell 22 form a stable support and guiding structure, and at the same time, a flow space is formed between the concave and convex plates 21, which reduces the heat accumulation of the two adjacent battery pack assemblies 40 and keeps the battery pack assembly 40 at a suitable working temperature. In addition, since the side of the limiting guide shell 22 close to the end cover plate 43 is a slope, the battery pack assembly 40 can be naturally guided to slide to the correct position when it is placed on the supporting assembly 20, reducing the difficulty of alignment during installation, and the final fixation of the battery pack assembly 40 on the support frame assembly 10 is achieved through the limiting screw 6 and the butterfly bolt 7. At the same time, the butterfly bolt 7 facilitates quick tightening and loosening, thereby improving the flexibility of maintenance.

[0044] The concave-convex plate member 21 includes a concave-convex plate 211. The top of the concave-convex plate 211 is formed with at least two upper planar protrusions 212, and the bottom of the concave-convex plate 211 is formed with at least two lower planar protrusions 213. The concave-convex plate 211 is provided with a plurality of hollow grooves 214 at intervals. The upper planar protrusions 212 are provided with mounting openings 215. Rollers 216 are rotatably connected in the mounting openings 215. The rollers 216 are in rolling contact with the bottom of the battery pack body 41. The top of the battery pack body 41 is provided with spaced-apart limiting grooves 45 that match the lower planar protrusions 213. The bottom ends of the lower planar protrusions 213 are located in the limiting grooves 45 and are slidably connected thereto.

[0045] Furthermore, the surface area of ​​the concave-convex plate 21 is increased by the upper plane protrusion 212 and the lower plane protrusion 213, and the inner side surfaces of the upper plane protrusion 212 and the lower plane protrusion 213 respectively form flow cavities, so that the heat generated by the battery pack assembly 40 is dissipated into the surrounding environment, and cooperates with its surface to provide additional support points, thereby enhancing the carrying capacity and stability of the concave-convex plate 21, and at the same time cooperates with the hollow groove 214 to further promote the circulation and dissipation of heat generated by the battery pack assembly 40, thereby reducing the accumulation of heat on the concave-convex plate 21. In addition, during the installation or maintenance of the battery pack assembly 40, its bottom The rolling contact with the roller 216 reduces the friction resistance of the battery pack assembly 40 during installation, disassembly or maintenance, and when the battery pack body 41 is installed on the supporting assembly 20, the lower plane protrusion 213 will slide into the corresponding limit groove 45, ensuring that the battery pack body 41 is in the correct installation position, strengthening the stability of the battery pack assembly 40 on the supporting assembly 20, preventing displacement or loosening due to vibration or external force, and to a certain extent reducing the slight displacement of the battery pack body 41 caused by thermal expansion and contraction or external vibration during charging and discharging, thereby protecting the integrity of the internal structure of the battery pack body 41.

[0046] Elastic arc-shaped snap-fit ​​buckles 24 are connected to both ends of the top of the inner cavity of the limiting guide shell 22. Waist-shaped openings 25 are opened at both ends of the elastic arc-shaped snap-fit ​​buckle 24. Screws 26 connected to the limiting guide shell 22 are installed in the waist-shaped openings 25. The screws 26 are set apart from each other. The upper surface of the top limiting strip 42 is spaced apart with arc-shaped snap-fit ​​buckles 46 adapted to the elastic arc-shaped snap-fit ​​buckles 24.

[0047] Furthermore, the elastic arc-shaped snap-fit ​​buckle 24 is preferably made of spring steel. When the elastic arc-shaped snap-fit ​​buckle 24 is respectively snapped with the corresponding arc-shaped bayonet 46, the two ends of the end cover plate 43 are respectively embedded in the limit notch 5, and the limit screw 6 is located in the corresponding through hole 44, so that the staff can fix the limit. When the two ends of the battery pack assembly 40 are installed in the limit slot 23, the elastic arc-shaped snap-fit ​​buckle 24 is deformed by pressure and moves inward under the pressure applied by the operator, prompting the elastic arc-shaped snap-fit ​​buckle 24 and the arc-shaped bayonet 46 to snap into each other, further limiting the installation of the battery pack assembly 40, and causing the elastic arc-shaped snap-fit ​​buckle 24 to undergo elastic deformation during the maintenance and disassembly process of the battery pack assembly 40. Since the waist-shaped opening 25 is opened at both ends of the elastic arc-shaped snap-fit ​​buckle 24, a space is provided for the deformation of the elastic arc-shaped snap-fit ​​buckle 24, thereby allowing the battery pack assembly 40 and the supporting assembly 20 to be disassembled and separated.

[0048] Example 2, as Figure 6 As shown, based on Example 1, the utility model provides an energy storage container, including a box body 8 and a plurality of battery racks arranged in the box body 8, and a vent 9 is provided on the surface of the box body 8; the vent 9 promotes air circulation inside and outside the box body 8, thereby helping to reduce the heat generated by the battery rack and the battery pack assembly 40 during the charging and discharging process, and improving the heat dissipation efficiency.

[0049] The implementation principle of this embodiment is as follows: during the disassembly and assembly process, the staff guides the battery pack assembly 40 to move toward the inner cavity of the limiting guide shell 22 through the inclined surface at one end of the limiting guide shell 22. At this time, the lower plane protrusion 213 will slide into the corresponding limiting groove 45 to ensure that the battery pack body 41 is in the correct installation position, thereby enhancing the stability of the battery pack assembly 40 on the supporting assembly 20. At the same time, the elastic arc-shaped snap buckles 24 are deformed respectively and snapped into the lost arc-shaped snap-in 46 to limit the battery pack assembly 40. At this time, the two ends of the end cover plate 43 are respectively embedded in the limiting notch 5, and the limiting screw 6 is located in the corresponding through hole 44. The staff installs the butterfly bolt 7 to tighten the limiting screw 6 and the butterfly bolt 7 to realize the assembly and fixation of the battery pack assembly 40 on the support frame assembly 10, thereby reducing the difficulty and labor intensity of disassembly and assembly of the battery pack body 41.

[0050] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
