description The utility model provides an automatic power-off device for the collision of an electric automobile. The automatic power-off device comprises a control power source and a collision switch assembly, wherein the collision switch assembly comprises a plurality of collision switches which are connected in series and are arranged on a front bumper and/or a rear bumper of the electric automobile; one terminal of the collision switch assembly is connected with the other end of the control power source, and the other terminal of the collision switch assembly is connected with the control terminal of a controllable switch in a high voltage loop of the electric automobile. Through the adoption of the device, when the automobile is collided, a low-voltage control power source line is cut off to cut off the high voltage loop without sending a collision signal, so that catastrophic dangers of short circuits, shock, explosion and the like due to information transmission links and power off time delay are avoided, and the
