The invention discloses a vehicle lithium battery protection device, and belongs to the technical field of new energy automobile parts, the vehicle lithium battery protection device comprises a vehicle-mounted lithium battery mounting seat, the vehicle-mounted lithium battery mounting seat is connected with a ventilation plate, and the ventilation plate is connected with a vehicle-mounted lithium battery pack. According to the vehicle-mounted lithium battery pack, the bottom of the lithium battery protection plate can be well protected when the bottom of the lithium battery protection plate is collided by road obstacles, meanwhile, collision energy transmitted into the vehicle-mounted lithium battery mounting base can be reduced, and therefore the vehicle-mounted lithium battery pack can be well protected; the pressure intensity of a place with high air flow speed is small, and the pressure intensity of a place with low air flow speed is large, so that the pressure intensity above the weight reduction compensation plate is smaller than the pressure intensity below the lithium battery protection plate, lifting force is provided, and the lithium battery panel and the weight reduction compensation plate float upwards under the action of the lifting force; therefore, the load brought by the lithium battery protection plate to the new energy automobile can be reduced by using the pressure difference in the rapid running process of the new energy automobile.

    本发明公开了一种车用锂电池保护装置,属于新能源汽车零部件技术领域,包括车载锂电池安装座,所述车载锂电池安装座上连接有通风板,所述通风板上连接有车载锂电池组。本发明中,锂电池护板的底部在受到路面障碍物的碰撞时能够对锂电池护板的底部起到良好的保护作用,同时还能够减少碰撞能量传入车载锂电池安装座,从而能够对车载锂电池组起到良好的保护,根据伯努利原理,空气流流速高的地方压强小,空气流流速低的地方压强大,导致减重补偿板上方的压强小于锂电池护板下方的压强,提供上升力,在上升力的作用下锂电池板和减重补偿板上浮,从而能够在新能源汽车快速行驶的过程中利用压差将来自于锂电池护板对新能源汽车带来的负重。
