The invention relates to the technical field of electric automobile emergency rescue, and discloses an automatic battery ejection device for an electric automobile. The automatic battery ejection device comprises a battery box, when the battery box spontaneously combusts, a motor can be controlled to operate through a mobile terminal, the motor operates to drive a screw rod to rotate, the screw rod rotates to drive an L-shaped plate to descend, the L-shaped plate descends to drive a mounting plate to descend, so that the battery box on a mounting plate is separated from an automobile body andis positioned below automobile body; when the battery box is located below the automobile body, a thermal bimetal sheet is heated to be bent sufficiently and pushes a trigger rod to move leftwards, the trigger rod moves leftwards to trigger a collision switch, and then an electromagnetic valve is opened; and after the electromagnetic valve is opened, compressed air in a pressure storage tank enters an air cavity through an air outlet pipe to push a piston to move, the piston moves to push the battery box to move through a push rod and a vertical rod, the battery box is pushed out of the mounting plate through instantaneous thrust of the compressed air to be away from the automobile body, and therefore the battery box is prevented from completely burning the automobile body.

    本发明涉及电动汽车紧急救援技术领域,且公开了一种用于电动汽车的电池自动弹射装置,包括电池箱,电池箱自燃时,通过移动终端可控制电机运行,电机运行带动丝杆旋转,丝杆旋转带动L型板下降,L型板下降带动安装板下降,使安装板上的电池箱脱离车体,位于车体的下方,当电池箱位于车体下方时,热双金属片也受热发生足量的弯曲并推动触发杆向左移动,触发杆向左移动触发碰撞开关,从而使电磁阀开启,电磁阀开启后,储压罐内的压缩气体通过出气管进入气腔,进而推动活塞移动,活塞移动通过推杆和竖杆推着电池箱移动,利用压缩气体瞬时的推力把电池箱从安装板上推出,使其远离车体,防止电池箱把车体完全烧毁。
