The invention relates to the field of automobile manufacturing, and discloses a new energy automobile anti-collision threshold beam which comprises a front collision plate, the front collision plate is in a U shape, a supporting connecting plate is arranged on the inner side face of the front collision plate, and a longitudinal beam connecting plate is fixedly connected to one end of the side face of the front collision plate. A buffer layer connecting plate is welded to the side, away from the front collision plate, of the supporting connecting plate, a stress dispersion connecting plate is fixedly connected to the side, away from the supporting connecting plate, of the buffer layer connecting plate, and a battery protection soft plate is integrally and fixedly connected to the side, away from the buffer layer connecting plate, of the stress dispersion connecting plate. According to the anti-collision threshold beam of the new energy automobile, the impact resistance of the middle portion is enhanced, middle folding is avoided, and the battery module and passengers are protected; an efficient collision energy transfer path is constructed, and local stress is reduced; due to the design of a multi-layer anti-collision structure, the maintenance cost and the secondary accident risk are reduced.
