The invention discloses a new energy automobile battery pack anti-collision protection device in the technical field of lithium battery protection, and the device comprises a lithium battery assembly which is used for supplying power to a new energy automobile; a heat dissipation protection assembly is mounted at the bottom of the lithium battery assembly and is used for supporting the lithium battery assembly and dissipating heat in the lithium battery assembly; the lithium battery assembly comprises a shell and a lithium battery pack installed in the shell, and ventilation holes are formed in the four side faces and the top face of the shell respectively. The automobile state is detected through the driving state sensing assembly, when the automobile state reaches a preset value, the ventilation anti-collision assembly starts to be started, anti-collision protection can be conducted on the lithium battery assembly before collision, the lithium battery assembly can be protected in advance when the lithium battery is subjected to external collision, and meanwhile when the automobile runs normally, the lithium battery assembly can be prevented from being damaged. The ventilation anti-collision assembly can conduct ventilation and heat dissipation on the lithium battery pack, heat accumulation and short circuit in the lithium battery pack are avoided, and the use safety of the lithium battery pack is improved.

    本发明公开了锂电池保护技术领域的新能源汽车电池组防撞保护装置,包括锂电池组件,用于新能源汽车供电;锂电池组件的底部安装有散热保护组件,用于支撑锂电池组件并对锂电池组件的内部散热;锂电池组件包括外壳以及安装在外壳内部的锂电池组,外壳的四个侧面以及顶面分别开设有通风孔。本发明通过行驶状态传感组件检测汽车状态,当汽车状态达到预设值时,通风防撞组件则开始启动,可在撞击到来前对锂电池组件进行防撞保护,可在锂电池受到外部撞击时,提前对锂电池组件进行保护,同时,当汽车正常行驶时,通风防撞组件可对锂电池组件进行通风散热,避免锂电池组内部热量积累短路,提升锂电池组使用的安全性。
