In some embodiments of the invention, when vehicle is collided, collision prevention girders 18 from outside to inside inhale step by step by deformation crumple
Can, crumple energy-absorbing is deformed step by step and is broadly divided into three phases, is respectively: whole level-one crumple energy-absorbing stage, level 2 buffering energy-absorbing
Stage, three-level resistance to deformation energy-absorbing stage.
When the whole level-one crumple energy-absorbing stage, the variation of collision prevention girders 18 is as follows:
Referring to shown in Fig. 2 and Fig. 3, collides outer beam 17 and drive diagonal brace pilot beam 12 to 10 Direction distortion of first-level buffer inner wall beam
Crumple, 16 compressive deformation of cyclic deformation pilot beam, in other words, level-one crumple portion 1 deform crumple, this process to second level crumple portion 2
The structure of middle deformation absorbs local collision energy, balances out local collision impact, until easy crumple section 4 contacts first-level buffer inner wall
The contact point of beam 10, easy crumple section 4 and first-level buffer inner wall beam 10 is 5 phase of reinforcing beam in the middle part of first-level buffer inner wall beam 10 and second level
At friendship, first-level buffer inner wall beam 10 has stronger resistance capacity to deformation, leads to easy 4 continuous deformation of crumple section.
The whole level-one crumple energy-absorbing stage is mainly deformed by level-one crumple portion 1 and absorbs local collision energy, to be conducive to
Vehicle can be guaranteed that components are safer in cabin by lesser collision.
When the level 2 buffering energy-absorbing stage, the variation of collision prevention girders 18 is as follows:
Referring to shown in Fig. 2 and Fig. 4, with the increase of impact force, cyclic deformation pilot beam 16 and diagonal brace pilot beam 12 are held
Continuous to be deformed, due to 12 guiding role of diagonal brace pilot beam, easy crumple section 4 starts by 12 tension force effect of diagonal brace pilot beam of two sides
Under deformation is straightened, until easy crumple section 4 is straightened, to be conducive to be promoted the forced area of collision prevention girders 18, and then be conducive to mention
Collision prevention girders 18 are risen to the protective capacities of cabin and passenger.Wherein first-level buffer inner wall beam 10 is squeezed by the impact of diagonal brace pilot beam 12
Pressure, since inner end and the reinforcing beam 5 in the middle part of second level of diagonal brace pilot beam 12 are staggered, first-level buffer inner wall beam 10 can be buffered with diagonal brace
12 inner end junction of beam is deformed crumple, squeezes second-order deformation and reserves cavity 7, to realize that second-order deformation reserves 7 crumple of cavity
Energy-absorbing.16 continuous deformation of cyclic deformation pilot beam simultaneously, sector deformed cavity 15 are further compressed deformation, absorb collision process
Energy.
Level 2 buffering energy-absorbing stage, the further deformation crumple in level-one crumple portion 1 and the deformation crumple in second level crumple portion 2 make
The energy of collision is further absorbed, and easy crumple section 4 is straightened deformation and the compression of sector deformed cavity 15 and can buffer level-one
Shock loading is mutated caused by crumple portion 1 and 2 rigidity of structure difference of second level crumple portion, specifically, when vehicle is by can generate
When the collision in level 2 buffering energy-absorbing stage, cyclic deformation pilot beam 16 both ensure that the energy-absorbing in whole level-one crumple energy-absorbing stage was made
With, and when playing the level 2 buffering energy-absorbing stage, due to diagonal brace pilot beam 12 and the structure of cyclic deformation pilot beam 16 itself,

The overall structure of beam 18, or since vehicle moment is by biggish impact force, cyclic deformation pilot beam 16 can make whole one
The process in grade crumple energy-absorbing stage to level 2 buffering energy-absorbing stage is excessively relatively slow, to be conducive to improve the safety of occupant.
Three-level resistance to deformation energy-absorbing stage, the variation of collision prevention girders 18 are as follows:
Referring to shown in Fig. 2 and Fig. 4, with the increase that impact force continues, cyclic deformation pilot beam 16, diagonal brace pilot beam 12,
Colliding outer beam 17 can be pressed together, at this time high-intensitive rectangle reinforce cavity 9 with constantly, consumingly resistance to deformation energy
Power to realize that whole collision prevention girders 18 bear impact force, and impact force is transmitted with maintaining the global shape of collision prevention girders 18 not broken
To vehicle body energy-absorption box and longitudinal beam structure.
Three-level resistance to deformation energy-absorbing stage, reinforcement part 3 can keep as far as possible the arcuate shape of collision prevention girders 18 not broken, change
Yan Zhi, collision prevention girders 18 are domes in vehicle overlook direction, that is to say, that while collision prevention girders 18 have crumple characteristic, tool
Play the role of deforming self-locking limit, when reaching the three-level resistance to deformation energy-absorbing stage, whole collision prevention girders 18 are formed by self-deformation
The more rigid new construction section of structure, reinforcement part 3 guarantees that collision prevention girders 18 keep original radian constant as far as possible, to advantageously ensure that
The safety of occupant in driver's cabin.Collision prevention girders 18 do not influence the use of vehicle body other structures, and collision prevention girders 18 can cooperate original vehicle
Body energy-absorption box reaches multi-buffer and crumple function, to be conducive to the impact force being subject in collision prevention girders 18 being transferred to arch knot
On the vehicle body energy-absorption box at structure both ends, when so that collision prevention girders 18 bumping against the objects such as tree or electric pole, it can avoid to the greatest extent
Since the concentration of impact force causes the middle part of collision prevention girders 18 to be broken, and then advantageously reduce the injury generated to occupant.
