Description

Technical Field

[0001] This application relates to the field of battery technology, specifically to a battery rack and battery container. Background Technology

[0002] In the field of battery energy storage, battery containers are widely used in industrial and mining enterprises, business centers, ship docks, and research parks and confidential departments where power supply is insufficient or the grid is unstable, due to their advantages of high integration, high space utilization, and strong environmental adaptability. As a key component in battery containers that carries, positions, and fixes battery packs, the rationality of the structure and the reliability of the limiting mechanism directly determine the installation efficiency, operational safety, and service life of the battery system.

[0003] In the existing technology, the battery rack's method of fixing the battery pack has the following shortcomings:

[0004] ① Poor Fixing Consistency: Most systems use a single-point fixing method, which uses scattered bolts, clips, and other connectors to locally limit the position of a single battery pack. This method makes it difficult to ensure that multiple battery packs are in a uniform reference position after installation, and it is easy for some battery packs to be fixed too loosely and others too tightly, resulting in insufficient structural stability at the battery cluster level.

[0005] ② Lack of Multi-directional Restraint: During transportation or outdoor use, battery containers often face tilting, swaying, and high-frequency vibration conditions. Existing restraint structures are mostly designed for only one direction and cannot simultaneously constrain the movement of the battery pack in the X, Y, and Z coordinate axes. For example, some solutions only restrict the Y-axis offset through side baffles, but do not effectively restrain the vertical movement of the Z-axis or the forward and backward movement of the X-axis. This can easily lead to positional displacement of the battery pack under complex operating conditions, thereby damaging the electrical connection interfaces between battery packs, and even causing safety hazards such as battery pack collisions and shell damage.

[0006] Therefore, there is an urgent need for a battery rack with high limiting reliability that can achieve omnidirectional constraint of the battery pack along the X / Y / Z axes, in order to solve the problems of poor fixing consistency and insufficient multi-directional limiting in the existing technology, and to ensure the safe and stable operation of the battery container. Utility Model Content

[0007] In view of this, in order to solve the above problems, this application provides a battery rack and a battery container.

[0008] To achieve the above objectives, this application provides a battery rack, including a frame body and a support assembly disposed within the frame body. The support assembly includes multiple support plates, which divide the interior of the frame body into multiple accommodating spaces for placing a battery pack. The support plates are used to support the battery pack. A front limiting assembly and a rear limiting assembly are respectively disposed at both ends of the support plates. The front limiting assembly includes a fixed limiting strip, and the rear limiting assembly includes inverted L-shaped plates disposed on the left and right sides of the rear end of the support plate and stops fixed on the inverted L-shaped plates. The two stops on the left and right sides are respectively inserted into the bottom plate at the rear end of the battery pack to restrict the movement of the rear end of the battery pack.

[0009] Furthermore, the inverted L-shaped plate includes a vertical plate and an upper horizontal plate. The stop block is welded to the vertical plate, and the upper horizontal plate is pressed against the bottom plate at the tail of the battery pack to restrict the movement of the tail of the battery pack in the Z-axis direction.

[0010] Furthermore, the support assembly also includes baffles fixedly disposed on both sides of the support plate, the baffles being welded to the vertical bracket of the frame body.

[0011] Furthermore, the fixing limiting strip is detachably connected to the vertical support of the frame body.

[0012] Furthermore, the fixing limiting strip is rectangular plate-shaped, and a through hole is provided on the fixing limiting strip. A threaded hole that matches the through hole is provided on the vertical bracket.

[0013] Furthermore, a limiting block is provided on the surface of the fixed limiting strip facing the accommodating space. The limiting block is inserted into a limiting hole opened on the front bottom plate of the battery pack to limit the movement of the front of the battery pack in the x-axis, y-axis, and z-axis directions.

[0014] Furthermore, the frame body includes a top frame and a bottom frame disposed opposite to each other, as well as multiple vertical supports connecting the top frame and the bottom frame.

[0015] Furthermore, the inverted L-shaped plate is a sheet metal part, and the vertical plate is welded to the support plate.

[0016] This application also provides a battery container, including the battery rack as described in any of the above embodiments.

[0017] Compared with the prior art, the advantages of this application are as follows:

[0018] This application provides a battery rack, including a frame body and a support assembly disposed within the frame body. The support assembly includes multiple support plates, which divide the interior of the frame body into multiple accommodating spaces for placing battery packs. The support plates support the battery packs. A front limiting assembly and a rear limiting assembly are respectively disposed at both ends of the support plates. The rear limiting assembly is located at the rear end of the support plate and includes inverted L-shaped plates disposed on the left and right sides of the rear end of the support plate and stops fixed to the inverted L-shaped plates. The two stops on the left and right sides are respectively inserted into the bottom plate at the rear end of the battery pack to restrict the movement of the rear end of the battery pack. Furthermore, the front limiting assembly includes an integrated fixing limiting strip, which increases the consistency and reliability of battery cluster-level fixing, unlike the single-point fixing in the prior art. The aforementioned battery rack uses front and rear limiting components respectively set at both ends of the support plate to limit and fix the battery pack. Under tilting, swaying and vibration, combined with the specific limiting of the inverted L-shaped plate, the stop block and the limiting block, it effectively prevents the battery pack from moving or deviating in the X, Y and Z axis directions. It has the advantages of simple installation structure and high limiting reliability. Attached Figure Description

When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0033] The following is in conjunction with the instruction manual appendix. Figure 1-5 This application provides a detailed description of the battery rack 100 and battery container according to the embodiments of this application, so as to clearly and completely disclose the technical solution of this application, enabling those skilled in the art to accurately understand and implement the technical solution.

[0034] This application provides a battery rack 100, including a frame body 1 and a support component 2 disposed within the frame body 1. The support component 2 includes multiple support plates 20 and side baffles 21. The multiple support plates 20 divide the interior of the frame body 1 into multiple accommodating spaces 10 for placing battery packs. The support plates 20 are used to support the battery packs. A front limiting component 40 and a rear limiting component 30 are respectively disposed at both ends of the support plates 20. The front limiting component 40 includes a fixed limiting strip 400. The rear limiting component 30 includes inverted L-shaped plates 300 disposed on the left and right sides of the rear end of the support plates 20 and baffles 301 fixed on the inverted L-shaped plates 300. The two baffles 301 on the left and right sides are respectively inserted into the bottom plate of the rear end of the battery pack to restrict the movement of the rear end of the battery pack.

[0035] Specifically, the frame body 1 is made of high-strength metal material (such as Q235 carbon steel) and includes a top frame 11 and a bottom frame 12 arranged opposite each other, as well as multiple evenly distributed vertical supports 13. The top frame 11 and the bottom frame 12 are both rectangular frame structures welded from horizontal and vertical beams. The two ends of the vertical supports 13 are welded and fixed to the lower surface of the top frame 11 and the upper surface of the bottom frame 12, respectively, forming a three-dimensional frame that is sealed at the top and bottom and supported on all four sides. It can withstand the total weight of multiple battery packs and the additional force generated by external vibration and tilting, and provide a unified installation benchmark for the support component 2 and the battery pack, avoiding battery pack positioning deviation caused by installation benchmark offset.

[0036] The support component 2 is located inside the frame body 1 and is the core component that directly supports the battery pack and achieves initial positioning. Figure 1 , Figure 3 As shown, it includes multiple support plates 20 and side retaining strips 21. The support plates 20 are spaced apart along the height direction (Z-axis) of the frame body 1, with the spacing adapted to the height of the battery pack, dividing the interior of the frame body 1 into multiple independent accommodating spaces 10, each of which can accommodate one standard-sized battery pack. The support plates 20 are fully fitted to the bottom plate of the battery pack, which can evenly distribute the weight of the battery pack and avoid deformation of the bottom plate of the battery pack caused by local stress concentration. At the same time, the length of the support plates 20 is adapted to the length of the battery pack, ensuring that the front and rear ends of the battery pack are supported after it is placed in the frame.

[0037] The baffle 21 is fixed to the left and right sides of the support plate 20 along its length (y-axis). The height of the baffle 21 is higher than the upper surface of the support plate 20, and the outer side of the baffle 21 is welded to the vertical bracket 13 of the frame body 1. The baffle 21 provides initial lateral (x-axis) positioning for the left and right sides of the battery pack, preventing the battery pack from shifting to either side after being placed in the accommodating space 10 or under vibration conditions, thus laying the foundation for the precise positioning of the front and rear positioning components.

[0038] The front limiting component 40 provides omnidirectional limiting for the front of the battery pack. To achieve multi-directional limiting of the front of the battery pack along the X / Y / Z axes, a front limiting component 40 is provided at the front end of the support plate 20. The front end refers to the entrance end where the battery pack is placed into the accommodating space 10. Figure 1 , Figure 4 As shown, it includes a fixing limit strip 400 and a limit block 401. The fixing limit strip 400 is a rectangular plate structure, made of the same material as the frame body 1 to ensure strength matching. It is fixed to the vertical bracket 13 of the frame body 1 by a "detachable connection" method, which increases the consistency and reliability of battery cluster-level fixing, unlike the single-pack single-point fixing mode in the prior art. The fixing limit strip 400 has multiple through holes 402, and the vertical bracket 13 has corresponding threaded holes (not shown) that match the diameter of the through holes 402. The fixing limit strip 400 can be installed by passing bolts, screws, or other fasteners through the through holes 402 and screwing them into the threaded holes.

[0039] like Figure 4 As shown, the limiting block 401 is a columnar or boss-shaped structure, preferably made of high-strength metal. It is integrally formed or welded to the surface of the fixed limiting strip 400 facing the accommodating space 10, and the shape and size of the limiting block 401 are perfectly matched with the pre-set limiting holes on the front bottom plate of the battery pack. When the battery pack is fully placed into the accommodating space 10, the limiting block 401 can be precisely inserted into the limiting holes on the front bottom plate of the battery pack, realizing a triple limiting function, that is, restricting the movement of the front of the battery pack in the X-axis (front and back), Y-axis (left and right), and Z-axis (up and down) directions.

[0040] Compared to the existing "single-point fixing" mode, the front limiting component 40 achieves overall all-round limiting of the front of the battery cluster through the design of "integrated fixing limiting strip + limiting block", which greatly improves the consistency and reliability of the installation of multiple battery packs.

[0041] The rear limiting component 30 provides omnidirectional limiting for the rear of the battery pack. The rear limiting component 30 is located at the rear end of the support plate 20, such as... Figure 2 , Figure 3As shown, it includes an inverted L-shaped plate 300 and a stop block 301. The inverted L-shaped plate 300 is integrally stamped from sheet metal to ensure structural strength. It includes a vertical plate 3001 and an upper horizontal plate 3002 that are perpendicular to each other. The bottom of the vertical plate 3001 is welded to the rear edge of the support plate 20. The weld is a continuous full weld to ensure that there is no relative displacement between the inverted L-shaped plate 300 and the support plate 20, providing a stable installation base for the stop block 301. The upper horizontal plate 3002 extends horizontally into the accommodating space 10. Its lower surface is attached to the upper surface of the bottom plate of the battery pack tail to form a press-fit structure. The rigidity and vertical constraint of the upper horizontal plate 3002 restrict the Z-axis movement of the battery pack tail, and together with the limiting block 401 of the front limiting component, it achieves the Z-axis limiting of the entire length of the battery pack.

[0042] The stop block 301 is a rectangular metal block made of the same material as the inverted L-shaped plate 300. It is welded and fixed to the surface of the vertical plate 3001 facing the accommodating space 10. The stop blocks 301 on the left and right sides are symmetrically distributed, and the spacing is adapted to the slot spacing preset on the bottom plate of the battery pack tail. When the battery pack is placed into the accommodating space 10, the two stop blocks 301 on the left and right sides are respectively inserted into the slots on the bottom plate of the battery pack tail, realizing the all-round limiting of the battery pack tail, that is, limiting the battery pack tail in the X-axis. Combined with the limitation of the vertical plate 3001 on the Y-axis and the limitation of the horizontal plate 3002 on the Z-axis, the three-dimensional limiting of the tail is completed.

[0043] The battery rack 100 of this application achieves all-round, highly reliable limiting of the battery pack through the collaborative design of "frame body 1 - support component 2 - front limiting component 40 - rear limiting component 30". Specifically, through the bidirectional constraint of the front limiting block 401 and the rear stop block 301, combined with the pressing of the stop bar 21 and the upper horizontal plate 3002 of the inverted L-shaped plate 300, even under tilting, swaying and strong vibration conditions, the battery pack will not move or deviate in the X / Y / Z axis direction, effectively avoiding electrical connection failure or collision risk; further, the integrated fixed limiting bar 400 and the symmetrical rear limiting component 30 are combined to ensure that multiple battery packs are installed at a uniform reference, improving the consistency of the battery cluster.

[0044] like Figure 5 As shown, another embodiment of this application provides a battery container, in which the battery rack 100 described in any of the above claims is fixedly installed. The battery container can directly inherit the high stability and high reliability of the battery rack 100 without the need for additional complex limiting structures. At the same time, the modular design of the battery rack 100 can be precisely adapted to the internal space of the container, improving the integration efficiency and space utilization of the battery container, and further ensuring the safe and stable operation of large-scale energy storage systems.

[0045] In summary, the battery rack and battery container of this application, through reasonable structural design, solve the problems of insufficient battery pack positioning, complex installation, and poor consistency in the prior art, and have significant practicality and industrial application value.

It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the conception herein through the foregoing teachings or techniques or knowledge in related fields.
