The invention discloses a detachable rear collision cross beam assembly, which comprises an anti-collision rear beam and energy absorption boxes, wherein inserting plates are connected to two ends ofthe back side of the anti-collision rear beam, and positioning holes and first connecting through holes are formed in the surfaces of the inserting plates in a penetrating mode; the number of the energy absorption boxes is two, one end of each energy absorption box is connected with a mounting plate, and through holes are formed in the four corners of each mounting plate; second connecting throughholes are formed in the outer side of each energy absorption box in a penetrating manner; limiting holes are formed in the opposite surfaces of the two energy absorption boxes; the limiting holes correspond to the positioning holes; elastic pressing assemblies are arranged on the opposite surfaces of the two energy absorption boxes; positioning columns are connected to the telescopic ends of theelastic pressing assemblies and used for pushing the positioning columns to penetrate through the limiting holes to extend into the energy absorption boxes; and the inner ends of the positioning columns are of a conical structure. The detachable rear collision cross beam assembly has the beneficial effects that the detachable rear collision cross beam assembly is detachably mounted at the automobile tail, the dismounting and mounting operation is easy and convenient, the using effect is good, other tools are not needed for assistance, and the cost is facilitated to be saved.
