[0085] In related technologies, the chassis and side beams of the battery tray are made of die-cast high-density metal materials. In order to ensure the safety and durability of the battery tray, thicker materials are selected or the structural strength is increased. In order to ensure that the battery tray can withstand the weight, vibration and impact of the battery module, a more complex structure is designed, making the battery tray heavier and affecting system performance.

[0086] In this embodiment, the relatively arranged side beams 110, the front beam 120 and the rear beam 130 are sequentially combined to form a frame 100, and the spaced guard plates 200 serve as the chassis of the battery tray 1000.
