Description

Technical Field

[0001] This utility model relates to the field of main shell technology for new energy vehicles, specifically a main shell for new energy vehicles. Background Technology

[0002] As a core component of the power battery system, the main housing of a new energy vehicle primarily undertakes key functions such as protecting the battery pack, heat dissipation, support, and fixation. The PB62 main housing plays a crucial role in new energy vehicles, and its design, material selection, and manufacturing process directly affect the performance and safety of the battery system.

[0003] Despite significant advancements in the design and manufacturing of main casings for new energy vehicles, several shortcomings remain. Existing main casings suffer from air leakage in the threaded holes after machining the upper window cavity, leading to a decrease in overall quality and a low yield rate. Furthermore, due to mold structure limitations, core pre-injection holes cannot be designed in this area, which is also a location with significant wall thickness. This inevitably results in shrinkage cavities during die casting, and the large machining allowance severely damages the casing, causing significant air leakage during pressure testing. An excessive pursuit of lightweight design may reduce the structural strength of the casing, affecting safety and durability. In extreme environments (such as high temperature, high humidity, and dust), the casing may experience sealing problems, leading to battery moisture or contamination. After long-term use, the casing may suffer corrosion, deformation, or cracking, all threatening battery safety. In addition, the complexity of the casing design makes repairing or replacing the battery pack inconvenient, increasing maintenance costs. No solutions have yet been proposed for these technical issues. Utility Model Content
