Description

Technical Field

[0001] This utility model relates to the field of power battery technology, specifically to a module reinforcement structure. Background Technology

[0002] As a core component of electric vehicles, battery packs often feature dual-layer modules and water-cooling plates to meet high energy density requirements. However, the upper module's height presents challenges for its fixation, making it susceptible to damage under vibration and other conditions, potentially endangering personnel safety. Therefore, a high-strength structure is needed to prevent damage to the second-layer cells. Traditional battery packs primarily use a flat plate to support the second-layer module, typically 1.5-3mm thick. This plate is prone to deformation and breakage, especially in harsh environments such as mining areas and mountainous regions. Therefore, a high-strength structure is urgently needed to support the second-layer module. Utility Model Content

It is suitable for high-strength module structures installed on the second layer, as well as scenarios with extremely high requirements for the strength and rigidity of the battery pack structure, such as mining areas with bumpy road conditions.

[0008] Preferably, the end plate is provided with a plurality of long fixing holes vertically, and the pressure plate is provided with a first fixing hole corresponding to the long fixing holes.
