Lithium iron phosphate battery pack packaging device Technical Field

[0001] This utility model relates to the field of lithium iron phosphate battery pack technology, and more specifically to a lithium iron phosphate battery pack packaging device. Background Technology

[0002] Lithium iron phosphate (LiFePO4) batteries are a type of lithium-ion battery. Compared to other types of lithium batteries, such as lithium cobalt oxide or ternary lithium batteries, they offer higher safety and a longer cycle life. Common applications include electric vehicles, energy storage systems, power tools, and drones. For example, some Tesla models, especially those sold in China, may use LiFePO4 batteries. In energy storage systems, LiFePO4 batteries are likely to be favored due to their long lifespan and high safety.

[0003] During sales and transportation, lithium iron phosphate batteries are typically placed inside packaging boxes, sometimes with wooden frames inside, to provide protection during transport. However, because lithium iron phosphate batteries are prone to collisions during transport, the lack of specific protective devices makes them susceptible to damage. Therefore, there is an urgent need to design a packaging device for lithium iron phosphate battery packs to address these issues. Summary of the Invention

[0004] The purpose of this invention is to provide a lithium iron phosphate battery pack packaging device to address the aforementioned shortcomings in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A lithium iron phosphate battery pack packaging device includes a packaging box. A bottom buffer is provided at the bottom inside the packaging box. An embedded lithium iron phosphate battery pack is provided inside the bottom buffer. A top buffer is fitted on top of the lithium iron phosphate battery pack. The bottom buffer, the top buffer, and the lithium iron phosphate battery pack are all located inside the packaging box. The upper surface of the top buffer is flush with the top opening of the packaging box.

[0007] Preferably, the packaging box is a cardboard box, which is used to cover at least the top cushioning component, the lithium iron phosphate battery pack, and the bottom cushioning component.

[0008] Preferably, the top buffer includes an inverted frame, with a slot on the inner wall at the bottom of the frame, and several reinforcing ribs fixedly installed on both sides of the top of the frame, and crossbeams fixedly connected to the reinforcing ribs on both sides of the top of the frame.

[0009] Preferably, the lithium iron phosphate battery pack includes a battery core, and an outer edge plate is provided on the outside of the battery core. Handle rings are provided on both sides of the battery core, and two symmetrically distributed terminals are provided on one side of the battery core.

[0010] Preferably, the bottom buffer includes a base, with notches on the outer walls of the top two sides of the base, support arms fixedly connected to the outer walls of the bottom two sides of the base, and bases perpendicular to the support arms on the outer walls of the bottom two sides of the base.

[0011] Preferably, the lithium iron phosphate battery pack is fitted inside the top and bottom buffer components to form an integral structure, and the integral structure is installed inside the packaging box.

[0012] In the above technical solution, the lithium iron phosphate battery pack packaging device provided by this utility model has the following beneficial effects:

[0013] The top and bottom buffers of this invention are made of EPE pearl cotton. The top and bottom buffers wrap the lithium iron phosphate battery pack and place the entire structure inside the packaging box. This provides good protection for the lithium iron phosphate battery pack, absorbs vibration and collision during transportation, and prevents wear on the surface of the lithium iron phosphate battery pack.
