The invention provides an automobile anti-collision cross beam with the good energy absorption effect. The cross beam comprises a front beam structure, a first-stage energy absorption structure, a transverse column, a second-stage energy absorption structure, a third-stage energy absorption structure and a cross beam set, the first-stage energy absorption structure capable of buffering impact force in different directions is fixedly installed on the lower surface of the front beam structure, the transverse column is arranged below the first-stage energy absorption structure, the second-stage energy absorption structure capable of buffering impact force from the first-stage energy absorption structure to a certain degree is arranged in the transverse column, the second-stage energy absorption structure is elastically connected with the first-stage energy absorption structure, the third-stage energy absorption structure capable of buffering impact force from the second-stage energy absorption structure is fixedly installed on the lower surface of the transverse column, and the cross beam set is fixedly mounted on the lower surface of the third-stage energy absorption structure. The front beam structure, the first-stage energy absorption structure, the second-stage energy absorption structure and the third-stage energy absorption structure match one another, accordingly, high-benefit graded buffering effects can be realized, excellent energy absorption effects can be realized, and the integral cross beam set can be assuredly prevented from being deformed and damaged due to excessively high impact force.
