The invention provides a power battery protection device, and relates to the technical field of vehicles. The device comprises a plurality of bottom protection plates and a plurality of buffer pads, wherein the multiple bottom protection plates are sequentially arranged in the direction from the vehicle head to the vehicle tail, the multiple buffering pads are arranged between the multiple bottom protection plates and the power battery, a cavity structure is arranged at the joint of every two adjacent bottom protection plates, and each cavity structure comprises the corresponding buffering pad, the corresponding bottom protection plate close to the vehicle head, a cavity and the corresponding bottom protection plate close to the vehicle tail, and the bottom protection plate close to the direction of the vehicle head is adjacent to the bottom protection plate close to the direction of the vehicle tail. Therefore, the crumple potential energy is absorbed through the cavity structure, and high-strength protection can be carried out on the power battery.

    本申请提供了一种动力电池防护装置,涉及车辆技术领域。在所述装置中,包括多块底护板以及多个缓冲垫;其中,多块底护板由车头到车尾方向依次设置,多个缓冲垫设置于多个底护板与动力电池之间,并且相邻的底护板之间的连接处设置有空腔结构,该空腔结构包括缓冲垫、靠近车头方向的底护板、空腔以及靠近车尾方向的底护板,其中,靠近车头方向的底护板与靠近车尾方向的底护板为相邻的底护板。这样,通过空腔结构吸收溃缩势能,可以对动力电池进行高强度保护。
