The invention relates to the technical field of new energy automobile batteries, and discloses an explosion-proof and flame-proof battery pack for a new energy automobile. The explosion-proof and flame-proof battery pack comprises a shell and a battery panel group, an air inlet pipe is welded to the right end of the shell, and an air outlet pipe is welded to the left end of the shell; a driving motor is mounted on the inner wall of the left side of the shell through screws, and the output end of the driving motor is rotationally connected with a first rotating shaft through a bevel gear. The device is simple in structure and novel in design, the heat dissipation of a new energy battery is facilitated, and the temperature of the battery in use is reduced; a positive electrode and a negative electrode of the battery panel group are conveniently fixed, the positive electrode and the negative electrode of the battery panel group are prevented from loosening in the running process of the automobile, and dust is prevented from being accumulated at the positive electrode and the negative electrode of the battery panel group to influence electric conduction; a power supply is conveniently cut off, and the positive electrode and the negative electrode of the battery panel group are disconnected, so that protection is performed, the oxygen content in the shell is reduced, the combustion condition is blocked, and the explosion-proof and flame-proof battery pack is suitable for wide popularization.

    本发明涉及新能源汽车电池技术领域,且公开了一种用于新能源汽车上的防爆防燃电池组,包括壳体和电池板组,所述壳体的右端焊接有进气管,所述壳体的左端焊接有出气管,所述壳体的左侧内壁通过螺钉安装有驱动电机,所述驱动电机的输出端通过锥齿轮转动连接有第一转轴,该装置结构简单,设计新颖,便于对新能源电池进行散热,降低电池在使用时的温度,便于固定电池板组的正极和负极,避免电池板组的正极和负极在汽车行驶中松动,避免电池板组的正极和负极处堆积灰尘,影响导电,便于切断电源,使电池板组的正极和负极断路,从而进行保护,降低壳体内部的氧含量,阻断燃烧条件,适合广泛推广。
