[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model provides: a lithium battery module isolation structure, including a lithium battery isolation box 1, a reinforcing bracket 3 connected to the top of the lithium battery isolation box 1 via an outer frame eave 2, limit holes 4 distributed on the outer surface of the lithium battery isolation box 1, a positioning guide rod 5 detachably installed inside the limit holes 4, an outer protective plate 7 for protecting the lithium battery isolation box 1 slidably installed on the surface of the positioning guide rod 5, and a buffer protection component for protecting the lithium battery isolation box 1 provided on the inner surface of the outer protective plate 7; a mounting cover plate 16 movably installed on the top of the outer frame eave 2, and a protective top plate 19 for protecting the top of the lithium battery isolation box 1 connected to the top of the mounting cover plate 16.

[0022] It is worth noting that the coordinated arrangement of the lithium battery separator box 1, positioning guide rod 5, outer protective plate 7, mounting cover plate 16, and buffer protection component structure can improve the isolation and protection function of the lithium battery separator box for the lithium battery, effectively reduce the impact force on the lithium battery separator box from different directions, and further reduce the possibility of damage to the lithium battery.

[0023] Specifically, the buffer protection assembly includes: a protective baffle 10 connected to the inner surface of the outer protective plate 7, and a buffer soft pillar 11 connected to the surface of the protective baffle 10; wherein, an isolation protective plate 12 is connected to the end of the buffer soft pillar 11, and a protective soft pad 13 is adhered to the surface of the isolation protective plate 12. The isolation protective plate 12 is located on one side of the protective baffle 10, and both the isolation protective plate 12 and the protective soft pad 13 have through grooves on their surfaces.

[0024] Furthermore, the outer protective plate 7 protects the outer surface of the lithium battery separator 1, while the protective baffle 10 prevents the separator 12 from having through slots that directly connect to the outside, ensuring physical protection while improving heat dissipation. The buffer soft pillar 11 works in conjunction with the separator 12 to protect the lithium battery separator 1 and the internal lithium battery. The separator 12 and the protective soft pad 13 form a multi-level energy absorption structure, effectively mitigating external impacts or vibrations to the outer protective plate 7 and improving the structural protection. The through holes 9 and through slots also address heat dissipation needs, preventing heat accumulation due to sealing and improving battery safety.

[0025] The outer protective plate 7 has mounting guide holes 8 on its surface. The inner wall of the mounting guide holes 8 is slidably connected to the surface of the positioning guide rod 5. The outer protective plate 7 and the protective baffle 10 each have through holes 9 on their surfaces. A buffer spring 14 is fitted onto the surface of the positioning guide rod 5. One end of the buffer spring 14 is connected to the inner surface of the outer protective plate 7. An anti-detachment baffle 6 is connected to the outer end of the positioning guide rod 5.

[0026] Furthermore, the positioning guide rod 5 allows for the detachable installation of the limiting hole 4, enabling quick assembly and disassembly of the lithium battery isolation box 1 and the outer protective plate 7. The mounting guide hole 8 works in conjunction with the positioning guide rod 5 to facilitate the outer protective plate 7 in the event of an external impact, acting as a guide and limiter. The buffer spring 14 provides a buffering and impact-resistant effect. The outer protective plate 7 and the isolation plate 12 have through holes 9 on their surfaces, which provide physical protection while ensuring airflow, assisting in heat dissipation, and extending the service life of the lithium battery module inside the lithium battery isolation box 1 in high-temperature environments. The anti-detachment baffle 6 ensures assembly stability and prevents parts from falling off.

[0027] The outer frame eaves 2 has mounting holes 15 on its surface, and the mounting cover plate 16 has locking holes 17 that mate with the mounting holes 15 on its surface. Locking rods 18 are installed on the inner walls of the mounting holes 15 and the locking holes 17, and lifting handles 20 are installed on both sides of the protective top plate 19 on the surface of the mounting cover plate 16.

[0028] The outer frame 2 is the result of installing the mounting cover 16. The locking rod 18, in conjunction with the mounting holes 15 and 17, further enhances the stability of the mounting cover 16. The lifting handle 20 is a structure used for transporting the lithium battery separator box 1. The protective top plate 19 on the top of the mounting cover 16 and the lifting handle 20 protect the battery module from physical damage and facilitate transport. The distribution of the limiting holes 4 and positioning guide rods 5, in conjunction with the outer protective plate, allows for adjustment of the installation position or quantity according to actual needs, adapting to application scenarios of lithium battery modules of different sizes.

[0029] The positioning guide rod 5 and the surface buffer spring 14 can effectively ensure the protection effect of the outer protective plate 7 when it is subjected to external impact. In addition, together with the buffer soft pillar 11 on the inner wall of the outer protective plate 7 and the protective soft pad 13 on the isolation plate 12, a multi-buffered structure is formed to further reduce the damage of external impact force to the lithium battery isolation box 1, effectively reduce the possibility of lithium battery damage, and improve the protection of lithium battery.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
