[0017] (2) The frame beam of the battery tray of the new energy vehicle with a buffering function moves toward the placement frame through the L-shaped rod to contact and squeeze the polygonal block. The polygonal block is squeezed by the L-shaped rod and moves away from the fixed plate. The polygonal block moves away from the fixed plate and contacts the stabilizing frame to provide auxiliary fixed support for the battery module. The auxiliary support of the stabilizing frame and the polygonal block can prevent the battery module from loosening during the operation of the vehicle, thereby reducing potential safety hazards, and reducing the risk of failure caused by vibration or impact, thereby improving the safety of the overall vehicle system.

[0018] (3) The battery tray frame beam of the new energy vehicle with a buffering function squeezes the detection plate through the liquid entering the detection frame.
