For the problems referred to above, the invention provides a kind of secondary auto against energy-absorption box, it can absorb collision energy, makes collision pass to the evenly mild absorption of energy energy quilt of front anti-collision beam, thereby reaches protection vehicle and occupant's dual-use function.
Two shearing panels of the present invention are the both sides that symmetric form is distributed in force-guided stem, shear the other end of panel and the side shield on rear adapter plate and are fastenedly connected.
A kind of secondary auto against energy-absorption box, its technical scheme is such: one-level Energy Absorbing Structure is set between carbody shell and front anti-collision beam, secondary Energy Absorbing Structure is set between front anti-collision beam and front side member, it is characterized in that: one-level Energy Absorbing Structure is by being fastenedly connected described collision prevention girders, and the force-guided stem of one-level Energy Absorbing Structure is close to the inwall of the corresponding front end carbody shell of described front anti-collision beam; Secondary Energy Absorbing Structure is by being fastenedly connected described front side member, and the force-guided stem of secondary Energy Absorbing Structure is close to the inwall of described front anti-collision beam.
It is further characterized in that: described firsts and seconds collision energy-absorbing structure all drives one end of symmetrical shearing panel to produce plastic deformation by force-guided stem to carry out energy-absorbing.
Described panel energy absorber is specially shearing-type panel energy absorber.
One side of described shearing panel is fixed, with force-guided stem be connected and carry out shear deformation on one side.
Two described shearing panels form one group of one-level endergonic structure, and the middle junction of two described shearing panels is fastenedly connected with described force-guided stem, and the inwall of the corresponding front end carbody shell of described front anti-collision beam is close in the force side of described force-guided stem.
Two described shearing panels form one group of secondary endergonic structure, and the middle junction of two described shearing panels is fastenedly connected with described force-guided stem, and the inwall of described front anti-collision beam is close in the force side of described force-guided stem.

The specific embodiment
As shown in Figures 1 and 2, apparatus of the present invention energy-absorption box is mainly comprised of rubber buffer 1, one-level collision energy-absorbing structure 2, front anticollision beam of automobile 3, secondary collision energy-absorbing structure 4 and automobile front longitudinal beam 5, and wherein the installation of one-level collision energy-absorbing structure 2 and secondary collision energy-absorbing structure 4 can be on the straight line consistent with automobile front longitudinal beam 5.When rubber buffer 1 is received impact, first the distortion by himself absorbs a part of impact energy, yet the energy equivalence that rubber buffer 1 absorbs is limited, impulsive force is transferred to one-level collision energy-absorbing structure 2 subsequently, by the further apparatus with shock absorbing of one-level collision energy-absorbing structure 2, then impulsive force conducts to collision prevention girders 3, because collision prevention girders 3 is fixedly connected with secondary collision energy-absorbing structure 4, when collision prevention girders 3 is subject to impacting, impulsive force is reached to secondary collision energy-absorbing structure 4, now secondary collision energy-absorbing structure 4 absorbs collision energy again.
As shown in Figure 3: in apparatus of the present invention, one-level collision energy-absorbing structure 2 and secondary collision energy-absorbing structure 4 also can be arranged on the straight line consistent with automobile front longitudinal beam 5.The different part of installation method shown in this installation method and Fig. 1 is, after one-level collision energy-absorbing structure 2 deforms, can directly by its force-guided stem 9, power be passed to the front mounting plate 12 of secondary collision energy-absorbing structure 4, and not need, by front anti-collision beam 3, power is passed to secondary collision energy-absorbing structure 4.
As shown in Figure 4: one-level collision energy-absorbing structure 2 is fixedly connected with (welding or other mounting meanss) by its side shield 7 and rear adapter plate 8 with front anti-collision beam 3; Secondary collision energy-absorbing structure 4 is fixedly connected with respectively (welding or other mounting meanss) by its front mounting plate 12 and rear adapter plate 15 with front anti-collision beam 3 and automobile front longitudinal beam 5.If the force-guided stem 13 of the force-guided stem 9 of one-level collision energy-absorbing structure 2 and secondary collision energy-absorbing structure is not installed on same straight line, the i.e. two collision energy-absorbing structures installation of staggering, impulsive force reaches collision prevention girders 3 by collision energy-absorbing structure 2 so, then by collision prevention girders 3, impulsive force is reached to collision energy-absorbing structure 4.If the force-guided stem 13 of the force-guided stem 9 of one-level collision energy-absorbing structure 2 and secondary collision energy-absorbing structure is arranged on same straight line, impulsive force consumes energy and power is reached to secondary collision energy-absorbing structure 4 again to end position at one-level collision energy-absorbing structure 2 so, and last impulsive force is just applied on front anti-collision beam 3.
As shown in Figures 5 and 6: one-level collision energy-absorbing structure 2 forms by shearing panel 6, force-guided stem 9, side shield 7 and rear adapter plate 8, and wherein rear adapter plate has and the equiform square opening 10 of force-guided stem 9, and force-guided stem is play the guiding role.
As shown in Fig. 7, Fig. 8 and Fig. 9: secondary collision energy-absorbing structure is comprised of front mounting plate 12, force-guided stem 13, shearing panel 11, side shield 14 and rear adapter plate 15.Wherein, on adapter plate 15, have the square opening 17 identical with force-guided stem 13 shapes, force-guided stem 13 is play the guiding role; In addition, on rear adapter plate 15, also have bolt hole 16 to facilitate the connection with automobile front longitudinal beam 5.
