Description

Technical Field

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

[0002] In the field of lithium-ion battery energy storage containers, especially in non-walk-in lithium-ion battery energy storage containers, the reliability of battery module fixation directly affects the safe and stable operation of the energy storage system. Existing technologies typically employ complex fixing devices to achieve secure fixation of battery modules. The core idea behind these devices is to improve the fixing effect by adding multiple auxiliary components and complex connection structures.

[0003] However, the complex structural design leads to cumbersome processing procedures, requiring multiple complex processing technologies and the adaptation of multiple parts, resulting in high processing costs. At the same time, the complex structure makes the assembly process inconvenient, requiring more assembly time and reducing overall assembly efficiency.

[0004] The root cause of the above problems lies in the fact that existing technologies excessively pursue fixed reliability while neglecting structural simplicity, and fail to achieve a balance between fixed reliability and structural simplicity through reasonable structural design. Summary of the Invention

[0005] To address the problems existing in the background technology, the present invention provides a non-walk-in lithium battery energy storage container battery module fixing structure and its assembly method.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a non-walk-in lithium battery energy storage container battery module fixing structure, including a fixing plate one and a fixing plate two disposed on its inner side; both the fixing plate one and the fixing plate two are L-shaped structures; the main board of the fixing plate one has three oblong holes, the three oblong holes being one battery module connection hole and two fixing plate two connection holes respectively, the two fixing plate two connection holes being located at both ends of the battery module connection hole; the main board of the fixing plate two has multiple pre-drilled welding holes, and the support plate of the fixing plate two has two nuts pre-set, the two nuts being configured one-to-one with the two fixing plate two connection holes.

[0007] Furthermore, the middle of the two fixing plates is provided with a notch.

[0008] Furthermore, a reinforcing plate is welded between the support plate of the second fixing plate and the main plate.

[0009] Furthermore, the reinforcing piece is a right-angled triangle, and the right-angled sides of the right-angled triangle are welded and fixed to the support plate and the main plate of the fixing piece two, respectively.

[0010] Furthermore, the reinforcing sheet is made of cold-rolled sheet metal.

[0011] Furthermore, the fixing piece is made of cold-rolled sheet metal.

[0012] Furthermore, the second fixing piece is made of cold-rolled sheet metal.

[0013] The present invention discloses an assembly method for a non-walk-in lithium-ion battery storage container battery module fixing structure, the method comprising the following steps: S1: Attach the main board of the second fixing piece to the preset mounting surface of the battery rack guide rail, and position the second fixing piece through the pre-drilled holes for welding; S2: Weld and fix the fixing piece 2 to the battery rack guide rail; S3: Hoist the battery module to the installation area of ​​the battery rack guide rail, adjust the position of the battery module so that the fixing holes on the battery module are aligned with the battery module connection holes of the fixing plate one; S4: Align the two connecting holes of the two fixing plates with the two nuts on the fixing plate 2, pass the bolt through the connecting holes of the fixing plate 2 and tighten it with the corresponding nuts; S5: Pass the bolt through the battery module connection hole of the fixing plate one, connect it with the fixing hole on the battery module and tighten it to complete the fixed assembly of the battery module.

[0014] Compared with the prior art, the beneficial effects of the present invention are: This invention optimizes the fixing structure design, using only two core components, fixing plate one and fixing plate two, to fix the battery module. This solves the problems of complex structure and cumbersome processing steps in existing fixing devices, achieving the advantages of simple structure and streamlined process. By combining basic processes such as sheet metal bending, welding, and pressing holes, along with precise hole and nut matching design, and reinforced by the reinforcing plate at the bending point of fixing plate two, the invention simplifies assembly operations and improves assembly convenience while ensuring the reliability of the fixing target surface. It effectively balances fixing reliability and structural simplicity, overcoming the defects of low processing and assembly efficiency caused by the excessive pursuit of fixing effect in existing technologies. Overall, it is reliable and highly practical. Attached Figure Description

The main board of fixing plate 7 has three oblong holes penetrating its thickness direction through a pressing process, with a pressing hole diameter of 8-10mm. The three oblong holes are respectively a battery module connection hole 1 and two fixing plate 2 connection holes, which are located at both ends of the battery module connection hole 1. The main board of fixing plate 8 has multiple arrayed welding pre-drilled holes 5 penetrating its thickness direction through a pressing process, which are used to weld and fix fixing plate 8 to the battery rack guide rail. The hole diameter is 6-8mm and the hole center distance is set to 40-60mm to facilitate positioning and weld formation during welding operations. The support plate of the second fixing plate 8 is pre-welded with two nuts 3 of M8-M10 specifications. During the welding process, it is ensured that the axis of the nuts 3 is perpendicular to the mounting surface of the support plate of the second fixing plate 8. The two nuts 3 are set one-to-one with the two connecting holes 2 of the second fixing plate, and are used to form a bolt connection with the first fixing plate 7.

[0018] Furthermore, the middle part of the fixing plate 8 is provided with a notch 6, which is used to reduce weight and to avoid the fixing connection point of the battery module.
