Automobile intelligent shape memory alloy energy absorbing structure and control method thereof

Abstract

The invention discloses an automobile intelligent shape memory alloy energy absorbing structure and a control method thereof. The automobile intelligent shape memory alloy energy absorbing structure comprises an anti-collision beam main body, a front buffering energy absorber, a side collision preventing energy absorber and a microcomputer control system, wherein the anti-collision beam main body is connected with a longitudinal beam through a sleeve type energy absorbing box; the front buffering energy absorber is connected with the anti-collision beam main body through a shape memory alloy wire; the side collision preventing energy absorber is spliced at the two ends of the anti-collision beam main body; the rear end plate of the side collision preventing energy absorber is connected with the end part of the anti-collision beam main body through a shape memory alloy wire; and the microcomputer control system can control the heating temperature of the shape memory alloy wire. The invention further discloses a control method for the automobile intelligent shape memory alloy energy absorbing structure. The invention is advantaged in that the automobile intelligent shape memory alloy energy absorbing structure can perform multi-stage controllable collision energy absorption under a plurality of collision environments to furthest protect passengers and vehicles.

Description

technical field [0001] The invention relates to the technical field of automobile safety, in particular to an intelligent energy-absorbing structure of a shape-memory alloy automobile and a control method thereof. Background technique [0002] With the increase of car ownership and frequent traffic accidents, car safety issues have become the focus of attention. Studies have shown that the probability of frontal collision, side collision and rear collision of automobiles is 39%, 38% and 23% respectively. The automobile industry stipulates that when a frontal collision occurs, the energy absorption rate of the energy-absorbing parts at the front of the automobile must be greater than 50%. Therefore, the thin-walled structure of the front of the car plays an extremely important role. [0003] Traditional energy-absorbing components at the front of automobiles, such as Chinese patents CN104943636A, CN100480102C, and CN204197064U, have a single structure, large mass, and low e...
