Description

Technical Field

[0001] This invention relates to a non-walk-in lithium battery storage container battery rack and its usage method, belonging to the field of lithium battery storage container technology. Background Technology

[0002] The battery rack is the core structure used to support and fix the battery modules. Among them, the battery module placement rail is a key component of the battery rack, which directly affects the installation stability and transportation safety of the battery modules.

[0003] In existing technologies, battery module placement rails for energy storage containers are mostly manufactured using bending and welding processes, resulting in a relatively simple structure. With the development of the energy storage industry, the application scenarios for energy storage containers are becoming increasingly diversified, and the requirements for structural stability and shock resistance during transportation are also significantly increasing. The existing simple battery module placement rails are no longer sufficient to meet the current usage and transportation needs of energy storage containers in terms of strength and functionality. Therefore, there is an urgent need to optimize the structure of the battery racks in energy storage containers to improve rail strength and add practical functions such as fixing, limiting, and positioning. Summary of the Invention

[0004] To address the problems existing in the background technology, the present invention provides a non-walk-in lithium battery storage container battery rack and its usage method.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a non-walk-in lithium battery storage container battery rack, comprising multiple sets of external columns and multiple placement guide rails; the multiple sets of external columns are arranged side by side along the length direction of the energy storage container, and multiple placement guide rails are welded and fixed to the opposite surfaces of each pair of adjacent sets of external columns, the multiple placement guide rails are arranged at intervals along the height direction of the external columns, and each pair of corresponding placement guide rails are arranged symmetrically from left to right; each placement guide rail includes a front limiting component, an upper bent sheet metal component, and a lower bent sheet metal component, the horizontal plate of the upper bent sheet metal component is welded and fixed to the horizontal plate of the lower bent sheet metal component, the outer side wall of the front end of the upper bent sheet metal component is fitted and fixed to the main part of the front limiting component, and the limiting part of the front limiting component is fixedly connected to the battery module; the rear end of the upper bent sheet metal component is provided with an anti-derailment bending part formed by bending upward and inward.

[0006] Furthermore, each set of outer columns is provided with a central column in the middle.

[0007] Furthermore, the outer pillar and the central pillar located in the middle are larger than the outer pillars and the central pillar on the left and right sides.

[0008] Furthermore, the anti-derailment bending part is provided with a limiting hole.

[0009] Furthermore, a sheet metal triangular piece is welded between the anti-derailment bending part and the upper bending sheet metal part, and the sheet metal triangular piece and the battery module base form upper and lower limits.

[0010] Furthermore, a nylon block is fixed to the rear end of the bent sheet metal part.

[0011] Furthermore, the vertical plates of the upper bent sheet metal part and the lower bent sheet metal part are provided with several reserved small holes.

[0012] A method for using a non-walk-in lithium battery storage container battery rack according to the present invention includes the following steps: S1: Push the battery module into the guide rail along the extension direction of the guide rail. The anti-derailment bending part blocks the battery module to prevent it from leaving the rail during the pushing process. S2: After the battery module is pushed into place, the metal pin of its base and the limiting hole form a mechanical engagement, while the sheet metal triangular piece abuts against the battery module base to achieve bidirectional limiting of the battery module. S3: The two sides of the battery module are attached to the nylon block; S4: Use the front limiter to lock and fix the battery module to the placement guide rail, thus completing the installation of the battery module.

[0013] Compared with the prior art, the beneficial effects of the present invention are: This invention utilizes upper and lower bent sheet metal parts welded together to form a placement guide rail, complemented by a support frame design with an outer column and a middle column. The large size of the middle column significantly enhances the overall structural strength and rigidity of the battery rack and placement guide rail, distributing the load and preventing deformation caused by stress concentration, thus improving load-bearing capacity and resistance to bumps. Simultaneously, by incorporating anti-derailment bending parts, limiting holes, sheet metal triangular parts, nylon blocks, and a front limiting component, a multi-dimensional limiting and fixing structure is formed, providing anti-derailment for battery module insertion, bidirectional upper and lower limiting, left and right limiting, and locking fixation. This enriches the fixing, limiting, and positioning functionality of the battery rack, effectively preventing displacement fluctuations of battery modules during transportation and use. Furthermore, the placement guide rail adopts a symmetrical left-right arrangement design, and pre-drilled small holes on the bent sheet metal parts improve the structural regularity and assembly adaptability of the battery rack. All components are assembled using conventional processes such as welding, simplifying processing and resulting in excellent overall structural stability. This design is fully adaptable to the use and transportation requirements of non-walk-in lithium battery energy storage containers. Attached Figure Description

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the invention, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0016] A non-walk-in lithium battery storage container battery rack includes multiple sets of external columns 6 and multiple placement guide rails 8. The multiple sets of external columns 6 are arranged side by side along the length of the energy storage container. Multiple placement guide rails 8 are welded and fixed to the opposite faces of each pair of adjacent sets of external columns 6. The multiple placement guide rails 8 are spaced apart along the height of the external columns 6, and each pair of corresponding placement guide rails 8 are arranged symmetrically from left to right. Each placement guide rail 8 includes a front limiting component 1, an upper bent sheet metal component 2, and a lower bent sheet metal component 5. The horizontal plates of the upper bent sheet metal component 2 and the lower bent sheet metal component 5 are welded together using a splicing welding process. The upper bent sheet metal part 2 is fixed to ensure the firmness of the welded joint, forming the main structure for placing the guide rail and improving the overall strength of the guide rail. The outer side wall of the front end of the upper bent sheet metal part 2 is attached and fixed to the main part of the front limit part 1. The four spot welding holes on the upper bent sheet metal part 2 are used as operating positions. The main part of the front limit part 1 is welded and fixed to the upper bent sheet metal part 2 by spot welding. The limiting part of the front limit part 1 is fixedly connected to the battery module. The limiting part of the front limit part 1 is vertically fixedly connected to the main part. The rear end of the upper bent sheet metal part 2 is provided with an anti-derailment bending part 9 formed by bending upward and inward, which is used to prevent the battery module from leaving the track during the process of pushing it into the guide rail.

[0017] Furthermore, each set of outer columns 6 is provided with a central column 7 in the middle, which can enhance the overall structural strength and rigidity of the support frame, distribute the load borne by the outer columns 6, prevent the outer columns 6 from deforming due to excessive local stress, and improve the load-bearing capacity and anti-bump deformation capacity of the battery rack. The outer columns 6 and central columns 7 are positioned and placed according to the internal layout and design height of the energy storage container to form the support frame of the battery rack.

[0018] Furthermore, the outer column 6 and the central column 7 located in the middle are larger than the outer columns 6 and the central column 7 on the left and right sides, which makes the load-bearing force of the support frame more reasonable. The large-sized central column strengthens the support performance of the core load-bearing point, effectively disperses the overall load of the battery rack, avoids structural deformation due to stress concentration in the middle, and further improves the overall stability and anti-bumping ability of the battery rack support frame, adapting to the overall load-bearing and transportation requirements of non-walk-in lithium battery energy storage containers.

[0019] Furthermore, the anti-derailment bending part 9 is provided with a limiting hole 10 through its thickness direction. The limiting hole 10 can form a mechanical engagement with the metal pin reserved on the battery module to prevent the battery module from fluctuating up and down during transportation.

[0020] Furthermore, a sheet metal triangular piece 4 is welded between the anti-derailment bending part 9 and the upper bending sheet metal part 2. The sheet metal triangular piece 4 and the battery module base form upper and lower limits to further prevent the battery module from fluctuating up and down.

[0021] Furthermore, a nylon block 3 is fixed to the rear end of the bent sheet metal part 2 by screws. The nylon block 3 is used to limit the left and right movement of the battery module.

[0022] Furthermore, the vertical plate of the upper bent sheet metal part 2 and the vertical plate of the lower bent sheet metal part 5 are provided with a number of reserved small holes. The reserved small holes are used to assemble other components, and the opening position of the reserved small holes can be flexibly adjusted according to the assembly requirements.

[0023] Both the outer column 6 and the middle column 7 are metal columns adapted to the size of the energy storage container, and are pre-cut and processed according to the design height. The front limit part 1, the upper bent sheet metal part 2, the sheet metal triangle part 4 and the lower bent sheet metal part 5 are all metal sheet metal parts. They are bent in advance according to the design shape, and spot welding holes, limit holes 10 and reserved small holes are opened at the corresponding positions. Nylon block 3 is a nylon component adapted to the limiting size, and the matching fixing plate, screws and bolts are all standard connecting parts.

[0024] Check the strength of all welds and the accuracy of the installation positions of each component to complete the overall welding and assembly of the energy storage container battery rack.

[0025] A method for using a non-walk-in lithium battery storage container battery rack according to the present invention includes the following steps: S1: Push the battery module into the guide rail along the extension direction of the guide rail. The anti-derailment bending part 9 blocks the battery module to prevent it from leaving the rail during the pushing process. S2: After the battery module is pushed into place, the metal pin of its base and the limiting hole 10 form a mechanical engagement, while the sheet metal triangular piece 4 abuts against the battery module base to achieve bidirectional limiting of the battery module and avoid vertical fluctuation during transportation. S3: The two sides of the battery module are attached to the nylon block 3, which limits the left and right movement of the battery module and prevents it from shifting left and right. S4: Using the front limiter 1 in conjunction with the matching fixing plate and screws, the battery module is locked and fixed to the placement guide rail through the battery module fixing hole, thus completing the installation of the battery module.

[0026] If other auxiliary components need to be assembled, they can be fixed and installed through the reserved small holes on the upper bent sheet metal part 2 and the lower bent sheet metal part 5 according to the assembly requirements.

[0027] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.
