Description

Technical Field

[0001] The utility model relates to the technical field of lithium batteries, in particular to an anti-disconnection lithium battery cell assembly mechanism. Background Art

[0002] Lithium batteries are a type of battery that uses lithium metal or lithium alloy as positive / negative electrode materials and a non-aqueous electrolyte solution. With the development of science and technology, lithium batteries are widely used in the current output of various low-speed vehicles.

[0003] In the prior art, a Chinese patent with publication number CN218731627U discloses an anti-disconnection lithium battery cell combination structure, which adopts the solution of "including a lower mounting plate, a connecting plate is arranged above the lower mounting plate, a cover plate is arranged above the connecting plate, side plates are arranged on the left and right sides above the lower mounting plate and on the left and right sides above the connecting plate, and multiple middle partitions are arranged above the lower mounting plate and above the connecting plate."

[0004] However, the above scheme still has some shortcomings. For example, the multiple partitions arranged between the battery cell bodies will reduce the air circulation on the outside of the battery cell bodies. When the heat on the outside of the battery cell bodies is high, the battery cell bodies cannot be quickly dissipated, resulting in high heat on the outside of each battery cell body, which is not conducive to the continuous power supply of the battery cell bodies. In view of this, we propose an anti-disconnection lithium battery cell combination mechanism. Utility Model Content
