[0015] Beneficial effects:

[0016] (1) The battery tray frame beam of the new energy vehicle with a buffering function is designed to manually pull the L-shaped plate upward when the battery module needs to be disassembled and repaired, so as to break away from the contact with the limit frame and release the limit on the limit frame. The L-shaped plate design can effectively prevent the battery module from being accidentally touched during maintenance, thereby reducing the risk of accidental loosening of the battery module during operation or maintenance. At the same time, the placement rod moves upward to drive the placement plate upward, and the placement plate moves upward to drive the battery module upward to pop out the battery module. A good buffering design can ensure the stability of the battery module during vehicle operation. At the same time, the quick disassembly and installation design reduces maintenance time, making the replacement of the battery module more efficient and ensuring that the vehicle can be restored to use faster, thereby improving operational efficiency.

[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. The detection plate is squeezed by the liquid entering the detection frame and moves in the direction away from the load-bearing plate. The movement of the detection plate in the direction away from the load-bearing plate drives the detection rod to move. The movement of the detection rod drives the protection plate to move. The protection plate moves out of contact with the protection hole and releases the seal of the docking hole, ensuring that the battery module is installed stably before docking, reducing the risk of damage or short circuit to the cable during installation, and preventing poor connection due to the movement of the battery module, thereby reducing the risk of loose cable interface or poor contact.
