Manufacturing of battery trays for new energy vehicles
Rivet nuts in the battery tray mainly serve the functions of connecting structural components and securing the battery module, while also providing sealing and protective functions.
Connecting structural components
Battery trays typically use aluminum profiles or steel as the main frame, forming a stable structure through precise welding. Rivet nuts (such as hexagonal pull rivet nuts) are installed on the tray bottom plate or side beams to connect components like the battery pack cover plate and fire extinguisher bracket, creating a sealed space to ensure the normal operation of the battery module.
Securing the battery module
Rivet nuts fix the battery module through press riveting or pull riveting processes, ensuring its stable position on the tray. For example, M8×25D wire thread inserts are installed on the bottom of the tray or module mounting beams to connect and secure three battery modules arranged side by side.
Sealing and protection
Some rivet nuts (such as pull rivet nuts) form an elastic adhesive film during connection, which can absorb impact and resist high temperature and high humidity environments, enhancing the tray's airtightness and corrosion resistance. For example, LM607 pull rivet sealing adhesive covers the flange area through a self-leveling process to prevent leakage risks.
Process adaptation
Aluminum tray processing needs to balance precision and strength, and the installation of rivet nuts must match the characteristics of the tray's aluminum profile or steel substrate. For example, the pull riveting process requires controlling deformation release hole design to avoid hole position shifts caused by welding shrinkage.
