[0002] Ring-shaped battery modules can utilize space more effectively. Compared to traditional modules, ring-shaped modules can accommodate more cells within the same volume, thereby increasing energy density. Furthermore, in ring-shaped battery modules, the cells are evenly distributed along the ring path, which helps to achieve more uniform heat dissipation, effectively reducing the temperature difference between cells in the module and improving the lifespan of the cells and the battery module. In existing ring-shaped battery modules, when one cell of the ring-shaped battery module has a problem, such as water ingress, it is often necessary to disassemble the entire battery module. This disassembly process not only causes manual inconvenience but may also lead to the loss of the entire battery module's functionality. Utility Model Content

[0022] To facilitate understanding of this utility model, a more comprehensive description of this utility model will be given below with reference to the accompanying drawings.

[0023] Please see Figures 1 to 2 A ring-shaped battery module 10 includes: multiple battery components 100 and multiple fixing components 200. The multiple battery components 100 are arranged sequentially to form a ring structure. Each battery component 100 includes a housing 110, multiple individual battery cells 120, a protection plate 130, and an output interface 140. Each individual battery cell 120 is disposed inside the housing 110. The protection plate 130 is disposed on one side of one of the individual battery cells 120. The output interface 140 is disposed on the top of the housing 110. Each individual battery cell 120 is electrically connected to the protection plate 130 and the output interface 140 in sequence. Each fixing component 200 is disposed between adjacent battery components 100, and adjacent battery components 100 are detachably connected through each fixing component 200.

[0024] It should be noted that by dividing the battery module into multiple battery components 100, each battery component 100 can be used individually or in parallel combination, making it suitable for various application scenarios and improving the flexibility of battery module use. Adjacent battery components 100 are sequentially and detachably connected via fixing components 200 to form a ring structure. When a single cell 120 of a battery component 100 fails and requires repair, the detachable connection structure between the fixing component 200 and the battery component 100 allows for quick and easy manual disassembly and replacement of the battery component 100, avoiding damage to the entire component during disassembly. To mitigate the risk of malfunction in individual battery modules, the output interface 140 is positioned on the top of the housing 110. This facilitates the neat connection of the wiring of each battery module 100, making it easier to locate the corresponding wiring when manually replacing the battery module 100. The protection board 130 is positioned on one side of one of the individual cells 120 of the battery module 100. Each individual cell 120 is sequentially electrically connected to the protection board 130 and the output interface 140. This not only prevents over-discharge of the battery module 100 through the protection board 130 but also simplifies the structure of the battery module 100, thereby reducing the production cost of the ring-shaped battery module 10.

[0025] Please refer to it again. Figures 1 to 2 In one embodiment, the battery assembly 100 includes a first limiting rib 150 and a second limiting rib 160. The first limiting rib 150 and the second limiting rib 160 are respectively disposed on both sides of the output interface 140, which can significantly enhance the deformation resistance of the output interface 140 and prevent the output interface 140 from deforming when the battery assembly 100 is subjected to impact.

[0026] Please refer to it again. Figure 2 In one embodiment, the outer casing 110 has a wiring port 111 and the first limiting rib 150 has a wiring port 151. The wiring port 111 and the wiring port 151 are arranged adjacent to each other, so that the wiring on the protection plate 130 can pass through the wiring port 111 and the wiring port 151 in sequence to connect to the output interface 140. This can avoid the first limiting rib 150 from blocking the wiring and make the wiring neater.

[0027] Please refer to it again. Figure 2 In one embodiment, the battery assembly 100 includes a plurality of limiting members 170, which are disposed on the top of the housing 110. The limiting members 170 are used to limit the wiring of the battery assembly 100, so that the wiring of the battery assembly 100 is neatly placed in the limiting members 170. The neat wiring makes it easier for manual disassembly of the faulty battery assembly 100, while avoiding the impact on the normal battery assembly 100 during the disassembly process.

[0028] Please refer to it again. Figure 2In one embodiment, a limiting part 112 is provided on one side of the outer casing 110. The limiting part 112 is recessed inward toward the individual cell 120, so that the individual cell 120 is tightly attached inside the outer casing 110. When the individual cell 120 vibrates, the tightly attached individual cell 120 is not easy to loosen or fall off.

[0029] In one embodiment, the housing 110 is filled with epoxy resin. The sealing properties of epoxy resin help prevent impurities such as moisture and dust from entering the battery assembly 100, thereby protecting the individual battery cells 120 from impurities and ensuring the long life and safety of the battery. At the same time, epoxy resin can further fix the individual battery cells 120 inside the housing 110, improving the stability of the individual battery cells 120.

[0030] Please refer to it again. Figure 1 In one embodiment, the fixing component 200 includes a connecting plate 210, a first fixing block 220, and a second fixing block 230. In a group of adjacent battery components 100, the first fixing block 220 is disposed on one of the battery components 100, and the second fixing block 230 is disposed on the other battery component 100. By using the connecting plate 210 to be detachably connected to the first fixing block 220 and the second fixing block 230 respectively, the adjacent battery components 100 are securely connected. When one of the battery components 100 in the ring battery module 10 needs to be disassembled, the detachable connection structure between the connecting plate 210 and the first fixing block 220 and the second fixing block 230 respectively allows for easy and quick manual disassembly of the battery component 100.

[0031] Please refer to it again. Figure 1 In one embodiment, the first fixing block 220 has a first fixing hole, the second fixing block 230 has a second fixing hole, one end of the connecting plate 210 has a first through hole, and the other end of the connecting plate 210 has a second through hole. The first fixing hole and the first through hole are aligned, and a first fastener 240 passes through the first fixing hole and the first through hole. The second fixing hole and the second through hole are aligned, and a second fastener 250 passes through the second fixing hole and the second through hole. With this arrangement, the connecting plate 210 and the first fixing block 220 are firmly connected by the first fastener 240, and the connecting plate 210 and the second fixing block 230 are firmly connected by the second fastener 250. This makes the adjacent battery components 100 firmly connected and less prone to loosening. The first fastener 240 and the second fastener 250 are screws. Screws have reliable connection, easy installation, and easy maintenance. They not only facilitate manual disassembly of the battery components 100, but also facilitate manual installation of new battery components 100.

[0032] In one embodiment, the connecting plate 210 is a metal connecting plate. The metal connecting plate has high strength, which improves the connection strength of adjacent battery components 100, thereby improving the impact resistance of the ring battery module 10.

[0033] Please see Figure 3 A stacked structure of a ring-shaped battery module 10 includes the aforementioned ring-shaped battery module 10. Multiple ring-shaped battery modules 10 are stacked and electrically connected. The stacked structure of the ring-shaped battery module 10 is suitable for scenarios with high power demand, thereby improving the flexibility of the ring-shaped battery module 10.

[0034] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
