Description

Technical Field

[0001] This utility model relates to the field of conductive copper busbar installation technology, specifically a conductive copper busbar installation and fixing structure for new energy vehicle battery packs. Background Technology

[0002] With increasing global attention to environmental protection and sustainable development, new energy vehicles, as a clean and efficient means of transportation, have experienced rapid development. In the battery pack, a key component of new energy vehicles, the conductive copper busbar plays a crucial role. As the conductive connection component between the various battery modules within the battery pack and between the battery pack and other electrical equipment, the performance of the conductive copper busbar directly affects the energy transmission efficiency and stability of the battery pack.

[0003] A utility model patent with publication number CN214898750U discloses a copper busbar fixing structure and a battery pack. The copper busbar fixing structure includes: a base for connecting to a foundation; a top cover located above the base, detachably connected to the base and forming a through-cavity; multiple limiting groups spaced vertically, each limiting group including a left limiting block on the left wall of the cavity and a right limiting block on the right wall of the cavity; and at least one partition plate detachably connected to the base and located between adjacent limiting groups. Each limiting group, together with the partition plate below it and / or the bottom of the cavity, forms an assembly layer for fixing the copper busbar. The left and / or right limiting blocks are elastically deformable to prevent the copper busbar from being inserted into the assembly layer and reset when the copper busbar is in the assembly layer to prevent it from leaving the assembly layer.

[0004] The conductive copper busbar fixing structure provided by the aforementioned patent can stably fix one or more copper busbars. However, in practice, conductive copper busbars are concentrated in some locations within new energy vehicle batteries. For example, a U-shaped conductive copper busbar may be installed on the left side of the front of the cable assembly, and a Z-shaped conductive copper busbar may be installed on the right side. Between these, there are also two sets of first conductive copper busbar groups arranged at intervals. These conductive copper busbars are used for connection between cells within the module and for current collection. Simultaneously, a second row of conductive copper busbar groups is generally installed on the front and rear sides of the battery module for internal electrical connections. While conductive copper busbars have excellent conductivity, they still possess resistance, which can cause heat generation. Concentrated conductive copper busbars can lead to poor heat dissipation, affecting the heat dissipation of the conductive copper busbars. Existing conductive copper busbar fixing structures lack structures to assist in heat dissipation of the conductive copper busbars, which is detrimental to heat dissipation. Utility Model Content
