The invention provides a front automotive auxiliary frame which comprises a front cross beam, a rear cross beam, a left longitudinal beam and a right longitudinal beam, wherein the left longitudinal beam orderly comprises a first front crumpling segment, a first transition segment and a first rear crumpling segment from front to back, and a first crumpling energy absorption rib is arranged on the first front crumpling segment; the right longitudinal beam orderly comprises a second front crumpling segment, a second transition segment and a second rear crumpling segment from front to back, and a second crumpling energy absorption rib is arranged on the second front crumpling segment; the first front crumpling segment, the second front crumpling segment and the front cross beam are on the same plane, and the first front crumpling segment and the second front crumpling segment are respectively parallel to the front end of a left front longitudinal beam of an automobile body and the front end of a right front longitudinal beam of the automobile body. According to the front automotive auxiliary frame, the left longitudinal beam and the right longitudinal beam of the automotive auxiliary frame is not easy to generate bending deformation to a passenger compartment, so that the amount of deformation of the passenger compartment can be reduced during collision, and the safety of passengers in the automobile is protected.
