Bottom battery guard plate
By incorporating a continuous fiber-reinforced thermoplastic resin layer and a honeycomb core layer into the battery bottom protector, and combining them with adhesive or film bonding, the problems of heavy weight, easy deformation, and easy rusting of existing battery bottom protectors are solved, achieving a lightweight battery bottom protector structure with high impact resistance.

AI Technical Summary
Existing battery bottom protection plate materials are heavy, easily deformed, and prone to rust, making it difficult to achieve lightweight and high impact resistance while ensuring safety.
The battery bottom protection plate structure is composed of a first continuous fiber reinforced thermoplastic resin layer, a metal layer, a second continuous fiber reinforced thermoplastic resin layer, a honeycomb core layer, and a third continuous fiber reinforced thermoplastic resin layer. It is connected by adhesive or film to increase the number of interfaces and improve energy absorption and impact resistance.
It achieves lightweighting, improved impact resistance and deformation resistance of battery bottom protection plates, while preventing rust, and is suitable for battery bottom protection plate materials.
