Frontal and off-set collision energy absorption device and automobile with the same

Abstract

The invention discloses a frontal and off-set collision energy absorption device and an automobile with the same. The energy absorption device is arranged at front end of an automobile frame, and comprises two longitudinal beams of energy absorption, one crossbeam of energy absorption, two supporting crossbeams, and two longitudinal beams of auxiliary energy absorption, wherein, a plurality of energy absorption bars and pilot holes are respectively arranged on the two longitudinal beams of energy absorption. The frontal and off-set collision energy absorption device can effectively induce sequential metal plastic deformation of a bearing carrier, which efficiently absorbs more than 80% of collision energy in a high-efficiency frontal collision energy absorption device; and during offset collision, longitudinal beams of unilateral collision energy absorption and longitudinal beams of auxiliary energy absorption efficiently absorb more than 70% of the collision energy, and transfer 20% of the collision energy to a non-collision by crossbeams, thus effectively reducing acceleration of an car body and passengers within a certain living space for the passengers, and reducing personal injury of the passengers caused by the frontal and off-set collision of the automobile.

Description

technical field [0001] The invention relates to a passive safety device used in automobiles, in particular to a collision energy high-density and high-efficiency absorption device for automobile frontal collision and offset collision body structure. Background technique [0002] For the cars currently produced in China, because domestic regulations only require a frontal crash test of 50km / h, the design target of car crash safety performance is the national frontal crash regulations (GB11551-2003). However, the offset collision resistance of its structure and the occupant protection performance are poor, and it is difficult to pass the 56km / h speed 40% offset collision requirement of the European ECE-R94 regulation. The reason is that the deformation and energy absorption space of the front part of the car body is small, and the bending rigidity of the front part of the main beam of the frame is weak. And the acceleration of the vehicle body and the occupant is high, which ...
