The invention relates to a sleeve type shape memory alloy car crash energy absorption box, and belongs to the technical field of car safety. An inner sleeve and an outer sleeve of the energy absorption box are in sleeving connection to form an energy absorption box body; the front end of the inner sleeve is fixedly connected with a front end plate of the inner sleeve; the rear end of the outer sleeve is fixedly connected with a rear end plate of the outer sleeve; a guide stud is fixedly connected to the rear end plate of the outer sleeve; the rear end plate of the inner sleeve is connected with the guide stud in a sliding manner; a nut is in threaded connection with the guide stud; one end of a shape memory alloy is fixedly connected with a front end cover of the outer sleeve, and the other end of the shape memory alloy is fixedly connected with the rear end plate of the inner sleeve. The sleeve type shape memory alloy car crash energy absorption box has the advantages that the structure is novel, the energy absorption effect can be improved effectively, the maintaining cost is reduced, and the safety of passengers in a passenger compartment is ensured.
