They are used only for the convenience of description and simplification of operation, and are not intended to 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.

[0034] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more. Furthermore, the terms "first" and "second" are used merely for descriptive distinction and have no specific meaning.

[0035] In one embodiment of this utility model, such as Figure 1-6As shown, a stable bracket for a battery module is provided, including: an upper reinforcing unit base 1, a lower reinforcing unit base 2, a connecting rod 7, and a middle connecting member 9. The upper reinforcing unit base 1 and the lower reinforcing unit base 2 are provided. The upper reinforcing unit base 1 is located on top of the lower reinforcing unit base 2. The opposite surfaces of the upper reinforcing unit base 1 and the lower reinforcing unit base 2 are provided with mounting grooves 4 for clamping batteries. The opposite back surfaces of the upper reinforcing unit base 1 and the lower reinforcing unit base 2 are provided with clamping holes 3. The connecting rod 7 is connected to the upper reinforcing unit base 1 and the lower reinforcing unit base 2. Both ends of the connecting rod 7 are provided with clamping blocks 8 for detachable connection with the clamping holes 3. The connecting rod 7 is provided with pressing blocks 19. The middle connecting member 9 is provided with a through hole 10 for the battery module to pass through in the middle. The edge of the middle connecting member 9 is provided with a support leg 11. The support leg 11 is supported on the opposite surface of the upper reinforcing unit base 1 or the lower reinforcing unit base 2. The pressing block 19 is pressed against the middle connecting member 9 on the upper reinforcing unit base 1 or the lower reinforcing unit base 2.

[0036] This utility model provides a stable bracket for battery modules. The central connecting piece 9 is fixed between the upper and lower reinforcing unit seats 2 via support legs 11. Combined with the clamping action of the clamping blocks 19, the overall structure is more stable, effectively coping with external forces such as vibration and impact, ensuring the safe and reliable operation of the battery module. The detachable connection between the clamping blocks 8 at both ends of the connecting rod 7 and the clamping ports 3 makes assembly and disassembly simple and quick, facilitating the maintenance, repair, or component replacement of the battery module, improving operational convenience and reducing maintenance costs.

[0037] Preferably, the mounting grooves 4 on the opposite surfaces of the upper and lower reinforcing unit seats 2 and the through holes 10 of the intermediate connector cooperate with each other to accurately clamp the battery, provide good positioning and protection, prevent the battery from being damaged by shaking or displacement during use, reduce the risk of the battery module being impacted by external forces, and thus extend its service life.

[0038] For preferred options, please refer to [the provided text]. Figure 1 Each upper reinforcing unit base 1 and lower reinforcing unit base 2 has a limiting block 12 on its adjacent sides. The opposing limiting blocks 12 on the sides of the upper and lower reinforcing unit base 1 and lower reinforcing unit base 2 have limiting openings 13 for engaging with the limiting blocks 12. The limiting blocks 12 and limiting openings 13 allow for easy splicing and combination of multiple upper reinforcing unit bases 1 and lower reinforcing unit bases 2. In large-scale battery module layouts, battery module arrays of different shapes and sizes can be flexibly constructed according to actual space and electrical connection requirements, improving the layout flexibility and space utilization of battery modules in various application scenarios.

[0039] For preferred options, please refer to [the provided text]. Figure 4The upper reinforcing unit base 1 or the lower reinforcing unit base 2 has grooves on their opposite surfaces for engaging the support legs 11. These grooves provide a precise positioning area for the support legs 11, allowing them to be quickly and accurately inserted during installation, greatly improving the assembly efficiency of the stable bracket. Simultaneously, the tight fit between the grooves and the support legs 11 effectively limits their horizontal displacement, enhancing the connection stability between the central connector 9 and the upper and lower reinforcing unit bases 2. This ensures the entire stable bracket maintains structural stability when subjected to external forces such as vibration and impact during operation, guaranteeing the safe and reliable operation of the battery module.

[0040] In this embodiment, the opposing surfaces of the upper reinforcing unit seat 1 or the lower reinforcing unit seat 2 are both smooth, allowing the middle connector 9 to be directly fitted onto the battery module. This not only simplifies the operation and eliminates the need for aligning with the groove, but also, in conjunction with the clamping block 19, ensures a stable installation of the battery module. Furthermore, when installing battery modules of different heights, the height of the support leg 11 can be appropriately selected to better stabilize the battery.

[0041] For preferred options, please refer to [the provided text]. Figure 3 The mounting groove 4 has an opening 5 on its bottom inner wall, and a stop 6 along the sealing direction of the opening 5 is provided on the bottom inner wall of the mounting groove 4. The stop 6 can accurately position the battery module and provide it with a stable support base, ensuring that the battery module always maintains the correct installation position within the stable bracket, reducing the risk of electrical connection failures caused by battery module shaking. The heat generated by the battery module during charging and discharging can be dissipated to the outside of the stable bracket more quickly through the opening 5, enhancing heat dissipation efficiency and effectively preventing performance degradation and shortened lifespan of the battery module due to overheating, maintaining the efficient and stable operation of the battery module.

[0042] For preferred options, please refer to [the provided text]. Figures 1-5 The connecting rod 7 has a thread in the middle, and the clamping block 19 is screwed onto the connecting rod 7. By rotating the clamping block 19, the optimal clamping position of the clamping block 19 on the upper and lower reinforcing unit seats 2 and the middle connecting piece 9 can be quickly adapted and determined according to the thickness and size of different battery modules and actual installation requirements, which greatly improves the efficiency of assembling and debugging the stable bracket and reduces the installation difficulty.

[0043] For preferred options, please refer to [the provided text]. Figure 3 The robust bracket also includes a stacking mounting assembly 14, located at the end of the connecting rod 7. The stacking mounting assembly 14 helps the robust bracket make full use of vertical space. Compared to traditional single-layer flat installation, multi-layer stacking installation reduces horizontal space occupation, making the battery module arrangement more compact and efficient.

[0044] For details, please refer to Figure 3The stacked installation assembly 14 includes a connecting hole 1401 and a connecting block 1402 that mates with the connecting hole 1401. The connecting hole 1401 is located at one end of the connecting rod 7, and the connecting block 1402 is located at the other end of the connecting block 1402. When the stable brackets are stacked, installers can quickly and accurately align the various stable bracket layers. The connecting block 1402 can be directly inserted into the connecting hole 1401 for initial positioning, greatly saving installation time and improving overall installation efficiency.

[0045] For preferred options, please refer to [the provided text]. Figure 1 The system comprises several connecting rods 7, each connected by a detachable positioning rod 15. In this embodiment, the length of the positioning rod 15 can be adjusted according to the array size of the battery module. When the battery module generates external forces such as vibration or impact during operation, the positioning rod 15 can evenly distribute these forces to each connecting rod 7, preventing any single connecting rod 7 from bearing excessive load. This significantly enhances the overall deformation resistance of the stable support, ensuring its stability under complex working conditions and effectively guaranteeing the safe and reliable operation of the battery module.

[0046] For preferred options, please refer to [the provided text]. Figure 3 The middle connector 9 has mating blocks 16 on its adjacent sides, and mating openings 17 on the opposite sides of the mating blocks 16 for mating with the mating blocks 16. During installation, installers can quickly align the mating blocks 16 with the mating openings 17 for splicing, without the need for complicated positioning and calibration operations, thus accurately connecting the middle connector 9 and effectively improving the overall assembly efficiency of the stable bracket.

[0047] For preferred options, please refer to [the provided text]. Figure 3 The corners of the central connector 9 are chamfered 18, which is used to cooperate with the connecting rod 7. Moreover, from the perspective of avoiding stress concentration, right-angled corners are prone to stress concentration when subjected to external forces, while the chamfer 18 can distribute the stress over a larger contact surface, effectively improving the structural strength and durability of the central connector 9.

[0048] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and modifications made to the above embodiments based on the present utility model without departing from the scope of the present utility model shall fall within the scope of the present utility model.
