Description

Technical Field

[0001] This utility model relates to the field of lithium battery technology, and in particular to a lithium battery cell assembly. Background Technology

[0002] With the rapid development of technology and the transformation of energy structure, lithium batteries, as an efficient and environmentally friendly energy storage and supply method, have been widely used in electric vehicles, mobile devices, energy storage systems, and other fields. Cylindrical cells are widely used in many fields due to their high energy density and reliability. However, compared with prismatic cells and pouch cells, their structure is inconvenient for stacking and alignment, and there is a risk of displacement during the assembly and welding process, thus becoming a problem that urgently needs to be solved.

[0003] Existing technology requires removing the top plate by unscrewing screws before installing the battery cell assembly, which is inconvenient. Furthermore, installing the battery cell assembly requires two motors to work together to install the cell and seal the casing, resulting in higher costs; additionally, the strong overall sealing hinders heat dissipation from the battery cell assembly.

[0004] The information disclosed in the background section is only intended to enhance the understanding of the background of this utility model, and therefore may contain information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0005] The purpose of this invention is to provide a lithium battery cell assembly that improves the installation efficiency, structural stability and reliability, and heat dissipation, thereby extending the service life of the cell assembly.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model provides a lithium battery cell assembly comprising:

[0008] The outer shell is an open structure.

[0009] A cover that detachably covers the outer casing, the cover having a slot for the lithium battery cell to pass through.

[0010] A placement plate, which is fixedly connected inside the housing to hold lithium battery cells, has through slots.

[0011] A heat dissipation window is provided on the outer casing and located below the placement plate.

[0012] Multiple mounting bases are fixed to the upper surface of the placement plate, and each mounting base has a first groove adapted to the outline of a lithium battery cell.

[0013] The detachable base is engaged in a slot, and the detachable base has a sliding groove.

[0016] Multiple rectangular plates, which are fixedly connected to the threaded block.

[0017] Multiple connecting rods, one end of which is fixedly connected to the rectangular plate.

[0018] Multiple clamping seats are fixedly connected to the other end of the connecting rod. Each clamping seat has a second groove adapted to the outline of the lithium battery cell. The second groove cooperates with the first groove to clamp the lithium battery cell.

[0019] The lithium battery cell assembly also includes,

[0020] Multiple limiting blocks are fixedly connected to the inside of the outer shell, and limiting holes are formed inside the limiting blocks.

[0021] The limiting rod has one end connected to a rectangular plate located at the edge, and the other end inserted into the limiting hole.

[0022] In the lithium battery cell assembly described above, the limiting rod is telescopically connected to a rectangular plate located at the edge.

[0023] In the lithium battery cell assembly described above, the lithium battery cell has a cylindrical structure, and both the first groove and the second groove are arc-shaped grooves.

[0024] In the lithium battery cell assembly described above, the arc-shaped groove is a semi-circular groove.

[0025] In the lithium battery cell assembly described above, the outer casing is an open rectangular parallelepiped structure.

[0026] In the lithium battery cell assembly described above, multiple connecting rods are evenly arranged on a rectangular plate.

[0030] In the above technical solution, the lithium battery cell assembly provided by this utility model has the following beneficial effects: After placing the battery cell assembly inside the housing, the detachable base is then placed inside the slot. Turning the knob then synchronously fixes the detachable base and the battery cell assembly, effectively improving the installation efficiency and structural stability of the battery cell assembly. Furthermore, it eliminates the need for any electrical equipment, resulting in a very cost-effective overall design. The placement plate, through-slot, and heat dissipation window effectively dissipate heat during the battery cell assembly's use, thereby extending its lifespan. The lithium battery cell assembly can easily accommodate multiple cylindrical cells. Attached Figure Description
