Description

Technical Field

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

[0002] Energy storage battery modules are the core units of large-scale energy storage systems, and their installation structure must simultaneously meet multiple requirements, including cell fixing, electrical connection, structural strength, and heat dissipation management. Currently, improving the assembly efficiency and maintainability of modules has become crucial for reducing system manufacturing and operation and maintenance costs.

[0003] In existing technologies, the installation structures of energy storage modules mainly fall into two categories. One type uses an integral frame secured with numerous screws for series connection. This method offers structural stability but involves cumbersome assembly processes and inconvenient replacement in case of a single cell failure. The other type employs a modular approach, such as using multiple independent plastic brackets to clamp the cells, supplemented by external binding or end plate clamping. This method simplifies assembly, but its structural rigidity and long-term connection reliability still need improvement when facing long-term vibration and cyclic expansion of the cells.

[0004] Therefore, the industry hopes to optimize existing modular technologies to find an installation solution that can ensure efficient assembly and convenient maintenance while providing higher structural integrity and connection reliability. Such improvements are of great significance for promoting the large-scale application of energy storage technologies. Utility Model Content

[0005] In view of this, the purpose of this utility model is to propose an energy storage module installation structure to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, this utility model provides an energy storage module installation structure, comprising: Multiple battery cells and busbars for electrical connections; Multiple upper and lower core holders with core slots are provided. The core slots are used to accommodate and fix the ends of the battery cells. Each upper core holder, lower core holder and battery cell constitute a battery unit. Adjacent upper core holders and adjacent lower core holders are detachably connected by locking blocks and slots provided on their sides to form an upper core holder array and a lower core holder array. The upper and lower sealing frames are respectively fitted outside the upper core seat array and the lower core seat array, and are connected to the inserts on the upper and lower core seats through slots provided on the upper and lower sealing frames. A locking mechanism, which is connected between the upper and lower sealing frames, is used to tighten the two to fix the entire module as a whole.

[0007] As a preferred embodiment of this utility model, the locking mechanism includes at least two locking parts disposed on both sides of the upper and lower sealing frames, each locking part comprising: Two buckles, one end of which has a positioning hole and the other end has a threaded rod; Positioning pins are fixed to the sides of the upper and lower sealing frames, and the positioning pins are engaged with positioning holes. The handle has internal threaded grooves at both ends that are adapted to the threaded rod. By rotating the handle, the two buckles can be moved closer together or further apart.

[0008] As a preferred embodiment of this utility model, the inner side of the positioning pin forms a recessed surface, and at least one positioning protrusion is provided on the recessed surface. The positioning protrusion engages with the positioning groove formed on the inner wall of the positioning hole.

[0009] As a preferred embodiment of this utility model, the upper and lower sealing frames have recessed cavities on one side of the corresponding positioning pins, and the depth of the recessed cavities is greater than or equal to the length of the positioning pins, so as to hide the positioning pins and buckles.

[0010] As a preferred technical solution of this utility model, the layout of the card block and / or card slot is asymmetrical to form a structure that prevents incorrect assembly.

[0011] As a preferred technical solution of this utility model, the upper sealing frame and / or the lower sealing frame are provided with weight-reducing grooves on their sides for reducing the weight of the module.

[0012] As a preferred embodiment of this invention, the upper core seat and the lower core seat are made of engineering plastics or composite materials.

[0013] As a preferred embodiment of this utility model, the lower core seat is provided with at least two insertion rods, which are engaged with positioning holes opened on the surface of the upper sealing frame.

[0014] The beneficial effects of this utility model are: 1. Achieved efficient and convenient modular assembly and maintenance: Through the "Lego-style" plug-in design of the upper and lower core seats and their card blocks and slots, the cells can be quickly spliced ​​laterally and initially positioned, greatly simplifying the assembly process. Combined with the installation of the upper and lower sealing frames and the quick operation of the locking mechanism, the assembly and disassembly of the entire module does not require special tools or a large number of screws, significantly improving production efficiency. When a single cell fails, the locking can be easily released and the sealing frame can be opened to replace the specific unit, effectively reducing maintenance costs and time.

[0015] 2. Excellent structural rigidity and connection reliability: This invention constructs a stable and reliable overall structure through triple mechanical protection of "core seat interconnection - frame reinforcement - mechanical locking". The upper and lower frames, fitted outside the core seat array, integrate the loose core seat connections into a high-rigidity overall frame through the cooperation of inserts and slots, effectively resisting deformation. The locking mechanism further provides strong clamping force, ensuring that the module maintains structural integrity and connection stability under long-term vibration, impact, and cell expansion conditions, fundamentally improving product safety and service life.

[0016] 3. This design integrates multiple optimized features to enhance practicality and safety: the specific snap-lock structure of the locking mechanism enables quick, effortless, and reliable fixing with adjustable locking force; the asymmetrical layout of the locking blocks and slots constitutes an effective anti-misassembly mechanism, ensuring assembly accuracy; the weight-reducing groove achieves lightweighting while maintaining strength; and the use of engineering plastics to manufacture the core base fundamentally guarantees the electrical insulation safety of the module. These designs collectively make this mounting structure more practical and competitive in the market. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0022] like Figure 1 , Figure 2 and Figure 3 As shown, an energy storage module installation structure includes: multiple battery cells 3 and a busbar 4 for electrical connection; multiple upper core seats 1 and lower core seats 2 with core slots 12, the core slots 12 being used to accommodate and fix the ends of the battery cells 3, each upper core seat 1, lower core seat 2 and battery cell 3 constituting a battery unit, adjacent upper core seats 1 and adjacent lower core seats 2 being detachably connected to each other through locking blocks 14 and locking slots 15 provided on their sides to form an upper core seat array and a lower core seat array; an upper sealing frame 5 and a lower sealing frame 6, respectively fitted outside the upper core seat array and the lower core seat array, and connected to the insert blocks 16 provided on the upper core seats 1 and the lower core seats 2 through slots 62 provided on the upper sealing frame 5 and the lower sealing frame 6; a locking mechanism 8, which is connected between the upper sealing frame 5 and the lower sealing frame 6, for pulling the two together to fix the entire module as a whole; The above technical solution solves the problems of low assembly efficiency and difficult maintenance caused by the use of numerous screws or integral frame welding in traditional battery modules. Specifically, its working principle is as follows: During assembly, the upper and lower ends of a single battery cell 3 are first inserted into the slots 12 of an upper core holder 1 and a lower core holder 2, respectively, to form a stable battery unit. Subsequently, by interlocking the locking blocks 14 and slots 15 on the sides of the upper core holder 1 of adjacent battery units, like assembling Lego bricks, multiple units are quickly connected horizontally to form upper and lower core holder arrays. Next, the upper sealing frame 5 and lower sealing frame 6 are respectively fitted onto the outside of the corresponding core holder array from top to bottom and from bottom to top, so that the slots 62 on the sealing frame and the inserts 16 on the core holder accurately match. This operation initially integrates the loose core holder array into an integral frame with high rigidity. Finally, the locking mechanism 8 connected between the upper and lower sealing frames is operated to generate a strong tension force, firmly fixing the upper sealing frame 5 and lower sealing frame 6 and all the components enclosed within them into a robust module as a whole.

[0023] like Figure 3 , Figure 5 and Figure 6 As shown, in this embodiment, the locking mechanism 8 includes at least two locking parts disposed on both sides of the upper sealing frame 5 and the lower sealing frame 6. Each locking part includes: two buckles 81, one end of which forms a positioning hole 82 and the other end forms a threaded rod 84; a positioning pin 54, which is fixed to the side of the upper sealing frame 5 and the lower sealing frame 6, and the positioning pin 54 is inserted and pulled into the positioning hole 82; and a handle 85, both ends of which form internal thread grooves 86 adapted to the threaded rod 84. By rotating the handle 85, the two buckles 81 can be driven to move closer to each other or further apart. The above technical solution solves the problems of cumbersome and inefficient traditional bolt tightening operations. Specifically, its working principle is as follows: During installation, the positioning holes 82 of the two buckles 81 are first inserted into the positioning pins 54 fixed to the sides of the upper and lower sealing frames 5 and 6, respectively. Then, the internal threaded grooves 86 at both ends of the handle 85 are aligned with the threaded rods 84 of the two buckles 81 and screwed in. By rotating the handle 85 clockwise, the two buckles 81 are driven to move closer together using the principle of the threaded pair, thereby pulling the upper and lower sealing frames 5 and 6 together, achieving final locking of the module. Reverse rotation of the handle 85 quickly releases the module, achieving fast, labor-saving, and adjustable locking force for module fixing.

[0024] like Figure 6 As shown, in this embodiment, a recessed surface is formed on the inner side of the positioning pin 54, and at least one positioning protrusion 55 is provided on the recessed surface. The positioning protrusion 55 engages with the positioning groove 83 opened on the inner wall of the positioning hole 82. The above technical solution can solve the problem that buckle 81 is easy to detach from positioning pin 54. Specifically, its working principle is as follows: when the positioning hole 82 of buckle 81 is inserted into positioning pin 54, the positioning groove 83 on the inner wall of positioning hole 82 is aligned with positioning protrusion 55. By pressing buckle 81, the positioning groove 83 and positioning protrusion 55 are engaged with each other, thereby locking buckle 81 and preventing buckle 81 from sliding and rotating along the axial direction of positioning pin 54, thus improving the stability of the module connection structure.

[0025] like Figure 6 As shown, in this embodiment, the upper sealing frame 5 and the lower sealing frame 6 have a recessed cavity 53 on one side of the corresponding positioning pin 54. The depth of the recessed cavity 53 is greater than or equal to the length of the positioning pin 54, so as to hide the positioning pin 54 and the buckle 81. The above technical solution solves the problem of external locking components being easily damaged by accidental bumps or snags on foreign objects during transportation or use. Specifically, its working principle is as follows: Recessed cavities 53 are provided on the sides of the upper sealing frame 5 and the lower sealing frame 6, with a depth sufficient to accommodate the entire positioning pin 54 and buckle 81. When the locking mechanism 8 is not in operation or after installation, the entire component can be completely stored within this recessed cavity 53. This achieves internalization and protection of the locking mechanism, resulting in a smoother external contour of the module, which is both safe and aesthetically pleasing, while also saving space.

[0026] like Figure 2 As shown, in this embodiment, the layout of the card block 14 and / or card slot 15 is asymmetrical to form a structure that prevents incorrect installation. The above technical solution can solve the problem of batch errors and rework caused by incorrect insertion of the core holder during manual or automated assembly. Specifically, its working principle is as follows: by arranging the locking block 14 and the slot 15 asymmetrically on the side of the core holder, it ensures that each upper core holder 1 or lower core holder 2 can only be inserted into the adjacent core holder in the single correct direction. During operation, if the direction is incorrect, the locking block 14 will not be able to be inserted into the slot 15, and assembly cannot proceed. This improves assembly accuracy and production efficiency, and reduces quality risks.

[0027] like Figure 3 and Figure 4 As shown, in this embodiment, the upper sealing frame 5 and / or the lower sealing frame 6 are provided with weight-reducing grooves 63 on their sides for reducing the weight of the module; The above technical solution solves the problems of excessive weight in energy storage modules, which affect system energy density and ease of handling. Specifically, its working principle is as follows: weight-reduction grooves 63 are formed on the sides of the upper frame 5 and / or lower frame 6 through stamping or injection molding. These weight-reduction grooves 63 remove material from some non-load-bearing or low-stress areas while ensuring the overall structural strength and rigidity of the frame. Without sacrificing performance, the overall weight of the module is significantly reduced, and material costs are saved.

[0028] Furthermore, in this embodiment, the upper core seat 1 and the lower core seat 2 are made of engineering plastics or composite materials; The above technical solution can solve the safety risks caused by internal short circuits in battery modules. Specifically, its working principle is as follows: the upper core holder 1 and the lower core holder 2 are manufactured using engineering plastics or composite materials through injection molding. Because these materials themselves have excellent insulation properties, when the battery cell 3 is installed in the core slot 12, it can effectively isolate the electrical connection between the battery cell 3 and the external metal structural components. This fundamentally improves the electrical insulation safety of the module. At the same time, engineering plastics also have advantages such as light weight, corrosion resistance, and ease of molding.

[0029] like Figure 3 and Figure 5 As shown, in this embodiment, at least two insertion rods 7 are provided on the lower core seat 2, and the insertion rods 7 are engaged with the positioning holes 82 opened on the surface of the upper sealing frame 5. The above technical solution solves the problem of misalignment causing the insert 16 to collide with the slot 62 and making it difficult to insert when closing the upper and lower sealing frames. Specifically, its working principle is as follows: when the upper sealing frame 5 is placed downwards, the insert 7 fixed on the lower core seat 2 will first insert into the pre-set positioning hole 82 on the surface of the upper sealing frame 5. This step precedes the engagement of the insert 16 and the slot 62, playing a role in initial positioning, realizing precise guidance and pre-positioning of the upper and lower sealing frames, making the subsequent fitting operation smoother and more accurate, and further improving assembly efficiency.

[0031] This utility model aims to cover all such substitutions, modifications, and variations that fall within its protection scope. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within its protection scope.
