The invention discloses an anti-collision auxiliary device for a new energy vehicle battery pack, which relates to the field of new energy vehicle batteries. A triangular block is arranged inside the longitudinal chute and the transverse chute, and the bottom end of the triangular block is connected with a spring. The invention realizes that the slider can slide in four directions at the top of the mounting plate, and judges which direction to push the slider according to the inclination information collected by the inclination sensor, so as to increase the counterweight of the automobile chassis, thereby reducing the probability of overturning, and achieving The purpose of protecting the battery, and after sliding, it is firstly locked by the triangular block with a special structure, and the slider cannot return to the original point until the driver judges that there is no danger of overturning, and controls the first motor, the first electric push rod and The second electric push rod is activated, and pushes the slider together with the battery case to the origin, which ensures smooth subsequent formation.
