The invention discloses a new energy automobile anti-collision device. The anti-collision device comprises an automobile chassis, a first detecting device is mounted at the front side of the automobile chassis, a second detecting device is mounted at the rear side of the automobile chassis, the automobile chassis is rotatably connected with connecting bases through rotating mechanisms, and anti-collision barrels are clamped to the connecting bases through clamping mechanisms. According to the anti-collision device, dynamic and static objects in the traveling direction of an automobile are detected by the first detecting device and the second detecting device, the detected information is transmitted to an open source single-chip computer, the open source single-chip computer analyzes and processes the information, the automobile is controlled to perform deceleration, braking, parking and other actions when it is determined that there is a danger, the intelligent degree is high, the usesafety of the anti-collision device is greatly improved, the anti-collision barrels are rotated through the rotating mechanisms when automobiles collide to decompose the impact force, and anti-collision measures are in place to meet the use requirements.
