Description

Technical Field

[0001] This utility model relates to the field of energy storage battery production technology, and in particular to an energy storage battery module container assembly. Background Technology

[0002] As a crucial carrier for storing and transporting electrical energy, the installation status of the battery modules inside energy storage containers directly impacts the safety and reliability of the entire energy storage system. Typically, multiple battery modules are mounted on the battery racks of an energy storage container. These modules are connected in series to form battery clusters, and multiple battery clusters further constitute a complete energy storage system.

[0003] To effectively control costs and improve space utilization, most shipping containers or energy storage cabinets adopt a single-side door design. While this design offers advantages in space utilization and cost control, it also introduces limitations to the battery module fixing method. Due to the single-side door limitation, the battery module can only be fixed at the front end of the door, making it difficult to achieve effective constraint behind it. Currently, the commonly used fixing method involves placing fixing blocks on the side beams of the battery module, creating a vertical constraint with the top of the battery guide rail. However, this fixing method only provides limited vertical constraint on the battery module and lacks sufficient constraint on displacement in other directions.

[0004] More importantly, due to limitations in existing assembly processes, a large gap must be reserved to ensure the battery modules can be smoothly installed in their designated locations, providing necessary space for movement. However, during the transportation of energy storage containers, the battery modules are highly susceptible to collisions with the battery brackets and surrounding components within this gap due to bumps and jolting, inevitably leading to serious safety hazards. Furthermore, as the transportation distance and number of trips increase, the damage caused by these bumps and collisions due to excessive gaps will accumulate, potentially leading to battery module failure, energy storage system malfunctions, and even the risk of serious safety accidents such as fires and explosions. Therefore, it is urgent for technical personnel to solve these problems. Utility Model Content

[0005] Therefore, in view of the above-mentioned existing problems and defects, the designers of this utility model collected relevant information, conducted multiple evaluations and considerations, and carried out continuous experiments and modifications by technical personnel with many years of R&D experience in this industry, which ultimately led to the emergence of this energy storage battery module container installation assembly.

[0006] This utility model relates to an energy storage battery module container mounting assembly, including individual battery cells, a sliding base frame, and a support assembly. The individual battery cells are situated on the sliding base frame, and their translational freedom is fully constrained due to the restraining force from the sliding base frame. The support assembly has a symmetrical split structure, using the left and right inner sidewalls of the container as its mounting base. The sliding base frame uses the support assembly as its side-pushing sliding assembly base, and its motion freedom is fully constrained.

[0007] As a further improvement to the technical solution disclosed in this utility model, the support assembly includes a left-side load-bearing beam, a right-side load-bearing beam, a left-side locking assembly, a right-side locking assembly, a left-side positioning pin assembly, and a right-side positioning pin assembly. The left-side load-bearing beam and the right-side load-bearing beam work together to serve as the lateral sliding foundation for the sliding base frame. The left-side positioning pin assembly and the right-side positioning pin assembly are respectively installed and fixed on the left-side load-bearing beam and the right-side load-bearing beam, respectively. A left-side guide horizontal notch adapted to the left-side positioning pin assembly is formed on the left-side beam of the sliding base frame. A right-side guide horizontal notch adapted to the right-side positioning pin assembly is formed on the right-side beam of the sliding base frame. At the end of the lateral sliding motion of the sliding bottom frame, the left positioning pin assembly and the right positioning pin assembly are inserted into the left guide horizontal notch and the right guide horizontal notch respectively. After the sliding bottom frame is pushed into place, the left locking component at its front end connects the sliding bottom frame and the left load-bearing beam, while the right locking component at its front end connects the sliding bottom frame and the right load-bearing beam.

[0008] As a further improvement to the technical solution disclosed in this utility model, the left-side load-bearing beam is formed with a left-side oblong hole for assembling the left-side locating pin assembly. The right-side load-bearing beam is formed with a right-side oblong hole for assembling the right-side locating pin assembly. The horizontal inclination angle of the left-side oblong hole is α, and the horizontal inclination angle of the right-side oblong hole is β, then 15°≤α=β≤45°.

[0009] As a further improvement to the technical solution disclosed in this utility model, the left-side locking assembly and the right-side locking assembly have the same design structure. The left-side locking assembly includes a left-side locking sheet metal part, a left-side upper bolt, a left-side middle screw, and a left-side lower bolt. Linearly arranged along its height direction, the left-side locking sheet metal part sequentially forms a left-side external upper mounting through hole, a left-side external middle mounting through hole, and a left-side external lower mounting through hole. Correspondingly, the left-side load-bearing beam forms a left-side internal upper mounting through hole and a left-side internal lower mounting through hole. A left-side internal middle threaded hole is located on the front side wall of the sliding base frame.

[0010] As a further improvement to the technical solution disclosed in this utility model, the sliding base frame includes a base frame and a stop and limit assembly. The base frame is assembled and welded from profiles and flat plates. The stop and limit assembly consists of a left-position stop sheet metal part, a front stop sheet metal part, a right-position stop sheet metal part, and a rear stop sheet metal part, which are detachably fixed to the top wall of the base frame and work together to constrain the translational freedom of the individual battery cells.

[0011] As a further improvement to the technical solution disclosed in this utility model, the support assembly also includes a left-side sheet metal adjusting component and a right-side sheet metal adjusting component. Multiple left-side sheet metal adjusting components are arranged linearly along the length of the left-side load-bearing beam and fixed by riveting. Multiple right-side sheet metal adjusting components are arranged linearly along the length of the right-side load-bearing beam and fixed by riveting. The left-side and right-side sheet metal adjusting components work together to change the width w of the lateral sliding space formed between the left-side and right-side load-bearing beams.

[0012] In practical applications, the energy storage battery module container assembly disclosed in this utility model can achieve at least the following beneficial technical effects, specifically:

[0013] 1) By effectively limiting the freedom of movement of the front and rear ends of the sliding base frame, and combining it with the side-pushing sliding assembly base and bracket assembly, the shaking space of the individual battery during transportation can be greatly reduced. Even in complex transportation environments such as bumps and vibrations, the relative displacement of the individual battery is strictly controlled within a reasonable range, significantly reducing the risk of damage caused by collisions and friction, and helping to reduce later maintenance costs.

[0014] 2) The individual battery is located on the sliding base frame, and its translational freedom is fully constrained. In addition, the front and rear movement freedom of the sliding base frame itself is also fully constrained, thus achieving stable fixation of the individual battery from multiple dimensions. This can effectively prevent the battery from shifting during transportation or during the operation of energy storage equipment due to factors such as bumps and vibrations.

Detailed Implementation

[0036] In the description of this utility model, it should be understood that the terms "left", "right", "front", "back", "up", "down", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0037] The present invention will be further described in detail below with reference to specific embodiments. Figure 1A perspective view of the energy storage battery module container assembly disclosed in this utility model is shown, indicating that it mainly consists of several parts, including a single battery cell 1, a sliding base frame 2, and a support assembly 3. Among them, as shown... Figure 2 As shown, the single-cell battery 1 is a regular cuboid, serving as the smallest unit for the interconversion of chemical energy and electrical energy, and is the cornerstone for constructing various energy storage systems. The single-cell battery 1 sits on a sliding base frame 2, and its translational freedom is fully constrained due to the restraining force from the sliding base frame 2. Figure 11 As shown, the support assembly 3 has a symmetrical split structure, and it uses the left and right inner walls of the container as its installation base. The sliding bottom frame 2 uses the support assembly 3 as its side-push sliding assembly base, and its degrees of freedom of movement are fully constrained.

[0038] As a preferred design solution, such as Figure 11 , Figure 13 , Figure 14 As shown, the support assembly 3 mainly consists of several parts, including a left-side load-bearing beam 31, a right-side load-bearing beam 32, a left-side locking assembly 33, a right-side locking assembly 34, a left-side positioning pin assembly 35, and a right-side positioning pin assembly 36. The left-side load-bearing beam 31 and the right-side load-bearing beam 32 work together to serve as the lateral sliding foundation for the sliding base frame 2. The left-side positioning pin assembly 35 and the right-side positioning pin assembly 36 are respectively installed and fixed on the left-side load-bearing beam 31 and the right-side load-bearing beam 32.

[0039] like Figure 3 , Figure 4 As shown, the sliding base frame 2 includes a base frame 21 and a stop and limit assembly 22. The base frame 21 is assembled and welded from profiles and flat plates. And as... Figure 5 , Figure 8 As shown, a left-side guide horizontal notch 211 is formed on the left beam of the foundation base frame 21 to match the left-side positioning pin assembly 35. A right-side guide horizontal notch 212 is formed on the right beam of the foundation base frame 21 to match the right-side positioning pin assembly 36.

[0040] During the assembly stage of the energy storage battery module container, at the end of the side-pushing sliding movement of the sliding base frame 2, the left positioning pin assembly 35 and the right positioning pin assembly 36 are inserted into the left guide horizontal notch 211 and the right guide horizontal notch 212 respectively. After the sliding base frame 2 is pushed into place, the left locking assembly 33 at its front end simultaneously connects the left beam and the left load-bearing beam 31 of the base base frame 21, while the right locking assembly 34 at its front end simultaneously connects the right beam and the right load-bearing beam 32 of the base base frame 21.

[0041] By adopting the above technical solution, the individual battery 1 is positioned on the sliding base frame 2, and its translational freedom is fully constrained. By effectively limiting the movement freedom of the front and rear ends of the sliding base frame 2, and in conjunction with its combination as a side-push sliding assembly base and support assembly 3, the shaking space of the individual battery during transportation is greatly reduced. Even in complex transportation environments such as bumps and vibrations, the relative displacement of the individual battery 1 is strictly controlled within a reasonable range, significantly reducing the risk of damage caused by collisions and friction, and also helping to reduce subsequent maintenance costs.

[0042] It should also be noted that the left-side load-bearing beam 31 and the right-side load-bearing beam 32 serve as the lateral sliding foundation for the sliding base frame 2, providing it with a stable movement track; and the cooperation between the left-side positioning pin assembly 35, the right-side positioning pin assembly 36, the left-side guide horizontal notch 211, and the right-side guide horizontal notch 212 enables precise positioning between the sliding base frame 2 and the support assembly 3; the connection between the left-side locking assembly 33 and the right-side locking assembly 34 at the front end of the sliding base frame 2 further enhances the assembly stability of the energy storage battery module container installation assembly.

[0043] According to feedback from assembly and debugging personnel, after the support assembly 3 is installed and fixed relative to the container, a flatness tolerance inevitably exists between the left-side load-bearing beam 31 and the right-side load-bearing beam 32. This can easily lead to difficulty in accurately aligning the left-side locating pin assembly 35 and the right-side locating pin assembly 36 with the left-side guide horizontal notch 211 and the right-side guide horizontal notch 212, which will inevitably cause considerable trouble for the installation operation. In view of this, as a further optimization of the above technical solution, such as Figure 15 , Figure 16 As shown, the left-side load-bearing beam 31 has a left-side oblong hole 311 for assembling the left-side locating pin assembly 35. The right-side load-bearing beam 32 has a right-side oblong hole 321 for assembling the right-side locating pin assembly 36. Let the horizontal inclination angle of the left-side oblong hole 311 be α, and the horizontal inclination angle of the right-side oblong hole 321 be β, then 15° ≤ α = β ≤ 45°. In this way, on the one hand, thanks to the certain tilt angle of the left-side waist-shaped hole 311 and the right-side waist-shaped hole 321, not only is it ensured that the left-side positioning pin assembly 35 and the right-side positioning pin assembly 36 have a certain adjustable displacement, but it also compensates to a certain extent for the vertical position deviation caused by the flatness tolerance of the left-side load-bearing beam 31 and the right-side load-bearing beam 32. On the other hand, during the installation process, the construction personnel can make fine adjustments to the relative positions of the left-side positioning pin assembly 35 and the right-side positioning pin assembly 36 according to the actual situation, ensuring that they fit tightly with the left-side waist-shaped hole 311 and the right-side waist-shaped hole 321. The left-side positioning pin assembly 35 and the right-side positioning pin assembly 36 work together to vertically constrain the sliding bottom frame 2, so that the sliding bottom frame 2 can be reliably and stably supported.

[0044] like Figure 11 , Figure 12 As shown, the left locking component 33 and the right locking component 34 have the same design structure and their implementation steps are similar.

[0045] like Figure 17 As shown, the left-side locking assembly 33 mainly consists of several parts, including a left-side locking sheet metal part 331, a left-side upper bolt 332, a left-side middle screw 333, and a left-side lower bolt 334. Linearly arranged along its height direction, the left-side locking sheet metal part 331 sequentially forms a left-side external upper mounting through hole, a left-side external middle mounting through hole, and a left-side external lower mounting through hole (not shown in the figure). Correspondingly, the left-side load-bearing beam 31 forms a left-side internal upper mounting through hole 312 and a left-side internal lower mounting through hole 313. The front side wall of the foundation frame 21 has a left-side internal middle threaded hole 213 (e.g., ...). Figure 6 , Figure 15 (As shown in the diagram). The left external upper mounting through hole, the left external middle mounting through hole, and the left external lower mounting through hole precisely engage with the left internal upper mounting through hole 312, the left internal middle threaded hole 213, and the left internal lower mounting through hole 313, respectively. In conjunction with the tightening action of the left upper bolt 332, the left middle screw 333, and the left lower bolt 334, the sliding base frame 2 is connected and fixed from the upper, middle, and lower positions along the height direction.

[0046] like Figure 18 As shown, the right-side locking assembly 34 mainly consists of several parts, including a right-side locking sheet metal part 341, a right-side upper bolt 342, a right-side middle screw 343, and a right-side lower bolt 344. Linearly arranged along its height direction, the right-side locking sheet metal part 341 sequentially forms a right-side external upper mounting through hole, a right-side external middle mounting through hole, and a right-side external lower mounting through hole (not shown in the figure). Correspondingly, the right-side load-bearing beam 32 forms a right-side internal upper mounting through hole 322 and a right-side internal lower mounting through hole 323. The front side wall of the foundation frame 21 has a right-side internal middle threaded hole 214 (e.g., ...). Figure 7 , Figure 15 (as shown in the image).

[0047] By adopting the above technical solution, both the left locking component 33 and the right locking component 34 are connected by a combination of multiple bolts and screws, which effectively enhances the structural stability of the energy storage battery module container installation assembly and effectively prevents the sliding bottom frame 2 from loosening relative to the left support beam 31 and the right support beam 32 due to the action of bumps or vibrations.

[0048] Once the individual battery cell 1 is fixed relative to the sliding base frame 2, to ensure that the translational freedom of the individual battery cell 1 is fully constrained, as a further refinement of the above technical solution, such as... Figure 9 As shown, the stop and limit assembly 22 consists of a left stop sheet metal part 221, a front stop sheet metal part 222, a right stop sheet metal part 223, and a rear stop sheet metal part 224, which are detachably fixed to the top wall of the base frame 21 and cooperate to constrain the translational freedom of the individual battery 1. Figure 10 As shown, the left-side backrest sheet metal part 221 has an upper folded backrest edge 2211 formed on it. In practical applications, after the single battery cell 1 is fixed relative to the base frame 21, the left-side backrest sheet metal part 221 and the right-side backrest sheet metal part 223 work together to limit its displacement in the left and right directions, preventing the battery from swaying horizontally; while the front-side backrest sheet metal part 222 and the rear-side backrest sheet metal part 224 work together to limit its displacement in the front and rear directions, ensuring that the single battery cell 1 has excellent anti-bump or anti-impact performance.

[0049] While ensuring that the individual battery cell 1 is effectively constrained, and considering the need to effectively expand the scenario adaptability of the support assembly 3, as a further optimization of the above technical solution, such as... Figure 11 , Figure 12 , Figure 19 As shown, the bracket assembly 3 is further equipped with a left-side sheet metal adjustment component 37 and a right-side sheet metal adjustment component 38. Multiple left-side sheet metal adjustment components 37 are arranged linearly along the length of the left-side load-bearing beam 31 and are fixed by riveting. Multiple right-side sheet metal adjustment components 38 are arranged linearly along the length of the right-side load-bearing beam 32 and are fixed by riveting. The left-side and right-side sheet metal adjustment components 37 and 38 work together to change the width w of the lateral sliding space between the left-side and right-side load-bearing beams 31 and 32. This allows for flexible selection and replacement of left-side and right-side sheet metal adjustment components 37 and 38 of different specifications according to actual conditions, quickly adapting to different specifications of the sliding base frame 2. This ensures smooth lateral sliding installation of the sliding base frame 2, avoiding installation difficulties or excessive gaps caused by mismatched space dimensions, and improving the smoothness and efficiency of the installation process.
