Description

Technical Field

[0001] This utility model relates to the field of lithium battery technology, specifically to a lithium iron phosphate battery pack with a heat dissipation structure. Background Technology

[0002] As is well known, lithium batteries have many advantages such as high operating voltage, high specific energy, small size, light weight, long cycle life, low self-discharge rate, no memory effect, and no pollution. Among lithium-ion batteries, lithium iron phosphate batteries are favored because of their high safety, more than 2,000 cycle life, stable discharge, fast charging, and non-toxic and environmentally friendly nature without heavy metals. Therefore, lithium iron phosphate batteries are currently the lithium-ion batteries with a very broad application prospect.

[0003] Most existing lithium battery packs use air cooling for heat dissipation. However, external impurities and dust in the air can easily enter the battery casing through the heat dissipation holes, which can cause damage to the battery. Therefore, a dustproof structure is needed to block impurities and dust. However, the dustproof structure is usually fixed with bolts. Therefore, when the dustproof structure needs to be cleaned, the operator needs to carry the corresponding disassembly and assembly tools to disassemble and assemble the dustproof structure. Without the tools, the operator cannot disassemble and assemble the dustproof structure. Utility Model Content

[0027] 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.

[0028] See Figures 1-3A lithium iron phosphate battery pack with a heat dissipation structure includes a housing 1, heat dissipation holes 10 on both sides of the housing 1, two sets of grooves 9 inside the housing 1, a battery pack body 8 inside the housing 1, heat dissipation components 2 on both sides of the housing 1, dustproof components 3 slidably disposed in the grooves 9, two sets of drive components 4 on the outside of the housing 1, and four sets of mounting components 5 on the outside of the housing 1.

[0029] Two sets of protective plates 6 are provided on the outer side of the housing 1. The protective plates 6 are located on the outside of the drive assembly 4 and the mounting assembly 5, and are used to protect the drive assembly 4 and the mounting assembly 5.

[0030] First, refer to Figure 1 and Figure 4 In this embodiment, the heat dissipation component 2 includes a mounting block 201 screwed onto the outside of the housing 1, and the mounting block 201 communicates with the heat dissipation hole 10. A mounting bracket 205 is welded inside the mounting block 201, and a fan motor 204 is provided on one side of the mounting bracket 205. The output end of the fan motor 204 is keyed to a fan blade 203, and two sets of ventilation meshes 202 are provided inside the mounting block 201.

[0031] When the fan motor 204 is turned on, its output will drive the fan blade 203 to rotate. The rotation of the fan blade 203 will generate heat dissipation airflow, which will then blow into the housing 1 through the heat dissipation hole 10.

[0032] Then, refer to Figure 1 and Figure 5 In this embodiment, the dustproof component 3 includes a movable plate 301 slidably disposed in the groove 9. The movable plate 301 is provided with a dustproof net 305 arranged parallel to the heat dissipation hole 10. Two sets of slots 302 are respectively opened on both sides of the movable plate 301, and the slots 302 and the locking blocks 502 are arranged parallel to each other. At the same time, the locking blocks 502 are engaged in the slots 302. When the locking blocks 502 are engaged in the slots 302, the movable plate 301 will be stably installed in the current position, and the fixing of the movable plate 301 will fix the dustproof net 305 in the current position.

[0033] Meanwhile, in order to facilitate the handling of the movable plate 301, handles 303 are provided on both sides of the movable plate 301, so that the operator can easily handle the movable plate 301 through the handles 303.

[0034] In order to align the card block 502 with the card slot 302, a blocking plate 304 is provided on the outside of the movable plate 301. The blocking plate 304 contacts the outside of the housing 1. Thus, when the blocking plate 304 contacts the housing 1, the movable plate 301 will be unable to continue moving, and the card slot 302 will align with the card block 502.

[0035] By setting the dustproof mesh 305 parallel to the heat dissipation hole 10, dust and other impurities entering the housing 1 through the heat dissipation hole 10 will be blocked by the dustproof mesh 305.

[0036] Secondly, see Figure 1 , Figure 2 , Figure 6 and Figure 7 In this embodiment, the drive assembly 4 includes a bearing 403 welded to the outside of the housing 1. A threaded tube 401 is provided in the middle of the bearing 403. Two sets of protective covers 7 are provided on the outside of the housing 1. The protective covers 7 are located outside the threaded tube 401. A sleeve 402 is screwed onto the outside of the threaded tube 401. A threaded hole adapted to the thread on the outside of the sleeve 401 is opened inside the sleeve 402. The sleeve 402 can be replaced with a rectangular plate. A connecting rod 409 is welded to the outside of the sleeve 402. A moving plate 404 is welded to the end of the connecting rod 409 away from the sleeve 402. Two sets of support plates 405 are welded to one side of the moving plate 404. A central shaft 406 is welded to the side of the support plate 405 near the sleeve 402. A pulley 407 is rotatably provided on the outside of the central shaft 406. The pulley 407 can be replaced with a circular top block.

[0037] To facilitate turning the threaded tube 401, a handle 408 is provided at the end of the threaded tube 401 away from the bearing 403, and the handle 408 penetrates the protective plate 6.

[0038] When the handle 408 is turned to rotate the threaded tube 401, the rotation of the threaded tube 401 will cause the outer threaded sleeve 402 to move linearly. When the sleeve 402 moves, it will drive the moving plate 404 and the support plate 405 to move through the connecting rod 409. The movement of the support plate 405 will drive the pulley 407 to move through the central shaft 406. When the pulley 407 moves upward, it will push the outer side of the swing plate 510.

[0039] See again Figure 1 , Figure 2 , Figure 8 and Figure 9 In this embodiment, the mounting assembly 5 includes a fixed shaft 511 screwed onto the outside of the housing 1 and a horizontal plate 501 slidably disposed on the outside of the housing 1. A swing plate 510 is rotatably disposed on the outside of the fixed shaft 511. The swing plate 510 is inclined and the two sets of swing plates 510 are inclined in opposite directions. A sliding groove 509 is provided inside the swing plate 510. Two sets of fixed plates 504 are welded to the side of the horizontal plate 501 near the swing plate 510. The side of the two sets of fixed plates 504 away from the swing plate 510 is welded to the top rod 505. The top rod 505 is slidably disposed in the sliding groove 509. Two sets of locking blocks 502 are bolted to the side of the horizontal plate 501 away from the fixed plate 504. The locking blocks 502 are locked in the dustproof assembly 3.

[0040] When the swing plate 510 is pushed, it will swing around the fixed shaft 511. At this time, the side of the swing plate 510 away from the fixed shaft 511 will swing towards the threaded tube 401. At the same time, when the swing plate 510 swings, it will pull the horizontal plate 501 to move laterally by pushing the top rod 505. The lateral movement of the horizontal plate 501 will drive the locking block 502 to move and disengage from the locking slot 302.

[0041] In addition, see Figure 2 , Figure 6 and Figure 7 In this embodiment, multiple sets of placement plates 508 are bolted to the outer side of the housing 1. A spring 507 is provided on one side of the placement plate 508. The end of the spring 507 away from the placement plate 508 is fixedly set to the horizontal plate 501. Therefore, when the horizontal plate 501 is pulled and displaced, the spring 507 will be squeezed by the horizontal plate 501. When the horizontal plate 501 is no longer pulled, the spring 507 will bounce the locking block 502 back by bouncing the horizontal plate 501 back, so that the locking block 502 can quickly return to the initial position and be locked into the slot 302.

[0042] Finally, see Figure 2 , Figure 6 and Figure 7 In this embodiment, a limiting rod 503 is provided on the side of the placement plate 508 near the spring 507. The horizontal plate 501 is slidably disposed on the outside of the two sets of limiting rods 503. Thus, on the one hand, the limiting rod 503 maintains the balance of the horizontal plate 501 during movement, preventing the horizontal plate 501 from becoming unbalanced and swaying during movement, and ensuring the normal displacement of the horizontal plate 501. On the other hand, the limiting rod 503 restricts the direction of the horizontal plate 501, preventing the device from failing due to misalignment of the horizontal plate 501.

[0043] Meanwhile, in order to prevent the horizontal plate 501 from disengaging from the limiting rod 503, a buffer pad 506 is provided on the outside of the limiting rod 503, and the buffer pad 506 is located on the side of the horizontal plate 501 close to the locking block 502. Thus, the movement of the horizontal plate 501 can be blocked by the buffer pad 506, preventing the horizontal plate 501 from disengaging from the limiting rod 503.

[0044] This lithium iron phosphate battery pack with a heat dissipation structure features a movable locking block 502. When removing the dustproof net 305 from the device, the movable locking block 502 disengages the dustproof net 305 from the slot 302, thus freeing the dustproof net 305 from being fixed. This allows the operator to easily remove the dustproof net 305 for cleaning. Simultaneously, when installing the dustproof net 305, the retraction of the locking block 502 will lock the dustproof net 305 in place by engaging it within the slot 302. This allows the operator to easily install and remove the dustproof net 305, avoiding situations where the dustproof net 305 cannot be removed due to a lack of tools.

[0045] Working principle:

[0046] When using this lithium iron phosphate battery pack with a heat dissipation structure, first place the battery pack in the desired location. Then, remove the dust filter 305 for cleaning. Specifically, turn the handle 408 to rotate the threaded tube 401. The rotation of the threaded tube 401 will cause the outer threaded sleeve 402 to move linearly. As the sleeve 402 moves, it will cause the moving plate 404 and support plate 405 to move via the connecting rod 409. The movement of the support plate 405 will cause the pulley 407 to move via the central shaft 406. When 407 moves upward, it will push the outer side of the swing plate 510. When the swing plate 510 is pushed, it will swing around the fixed shaft 511. At this time, the side of the swing plate 510 away from the fixed shaft 511 will swing towards the threaded tube 401. At the same time, when the swing plate 510 swings, it will pull the horizontal plate 501 to move laterally by pushing the top rod 505. The lateral movement of the horizontal plate 501 will drive the locking block 502 to move and disengage from the locking slot 302. At this time, the locking block 502 no longer locks the movable plate 301, and the operator can easily remove the movable plate 301 for cleaning.

[0047] Finally, install the cleaned movable plate 301. The specific operation is as follows: insert the movable plate 301 into the groove 9. When the blocking plate 304 contacts the housing 1, the movable plate 301 cannot move further. At this time, the locking block 502 aligns with the slot 302. Then, reverse the handle 408 to make the reverse rotation of the threaded tube 401 drive the pulley 407 to move back and no longer push the swing plate 510. At this time, the spring 507 will bounce the locking block 502 back by bouncing the horizontal plate 501 back, so that the locking block 502 can quickly return to the initial position and be locked into the slot 302. In this way, the locking block 502 can lock the movable plate 301, so that the dustproof net 305 can be stably installed in the housing 1.

[0048] 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.
