As depicted in figs. 1 and 2, in a specific embodiment, the utility model provides a kind of collision energy-absorbing device of automobile
10, which can be the extrudate of aluminum alloy material, and the collision energy-absorbing device 10 include crossbeam and
Core plate 13.Wherein, crossbeam has antetheca 11 and rear wall 12, when the collision energy-absorbing device 10 to be mounted in vehicle body, antetheca 11
Positioned at the front of rear wall 12, the two is oppositely arranged shape forming cavity.And the setting of core plate 13 is intracavitary in type, and connects antetheca 11 and rear wall
12.Specifically, there are two outer layer 131 and the interlayer 132 being distributed between two outer layers 131, the interlayers 132 for the core plate 13 tool
Multiple crumple chambers are separated to form in gap between two outer layers 131.
The collision energy-absorbing device 10 of above structure forms double crumple endergonic structure, first, before being come from by core plate 13
The impact force of wall 11 is transferred to rear wall 12, also, is connected to multiple core plates 13 between antetheca 11 and rear wall 12 for 11 He of antetheca
Cavity spacer between rear wall 12 at multiple crumples energy-absorbing chamber, while the process that impact force is transmitted along core plate 13, energy-absorbing
Chamber occurs crumple deformation and absorbs collision energy.Second, the interlayer 132 of each core plate 13 is in the gap between two outer layers 131
Multiple crumple chambers are formed again, and when impact force is transmitted along core plate 13 from antetheca 11 to rear wall 12, interlayer 132 is further by impact force
It is transmitted between two outer layers 131, while multiple crumple chambers inside the core plate 13 occur crumple deformation and absorb collision energy.Such as
This setting, forms the endergonic structure of two ranks, and after colliding, which absorbs collision energy step by step,
To effectively absorb the collision energy generated in collision process, it is ensured that the safety of vehicle.
Core plate 13 in the collision energy-absorbing device 10 of above structure forms the chamber of crumple chamber by outer layer 131 and interlayer 132
Structure, and antetheca 11 and rear wall 12 form the interconnection constraint between each core plate 13 in 13 orientation of core plate, in this way, by core
The cavity configuration that plate 13 provides can be associated with each other, so as to meet the needs of crumple energy-absorbing to ensure vehicle security, simultaneously
The weight for being sufficiently lowered collision energy-absorbing device 10 using cavity configuration again, is further decreased the weight of vehicle, met light-weighted
It is required that.
In a particular embodiment, since antetheca 11 and rear wall 12 are not to be mainly used to shock proof component, antetheca 11
Thickness t1 and the thickness t2 of rear wall 12 can be respectively less than the thickness t3 of core plate 13, sufficiently to reduce the weight of collision energy-absorbing device 10
Amount.
Even, the thickness t2 of the thickness t1 of antetheca 11 and rear wall 12 can further less than outer layer 131 thickness t4 and
Any one in the thickness t5 of interlayer 132.That is, antetheca 11 thickness t1 and rear wall 12 thickness t2 than outer layer 131 thickness
The thickness t5 of t4 and interlayer 132 is small.To which the collision energy-absorbing device 10 can use two that antetheca 11 and rear wall 12 are formed
Crumple energy-absorbing core plate 13 between the two is connected as an entirety by thin plate, to meet the requirement for absorbing collision energy, and is simplified
Structure makes it meet light-weighted design requirement.
Antetheca 11 and rear wall 12 opposite can be arranged in flat condition, also, antetheca 11 is parallel with rear wall 12, thus the company of being formed
The horizontal type chamber passed through.Alternatively, antetheca 11 and rear wall 12 can also be with identical curvature bendings, i.e. the shape of the two is identical, thus
Form coherent flexure type chamber.
Along the multiple core plates 13 of length extending direction arrangement of the two between antetheca 11 and rear wall 12, core plate 13 is in antetheca
Be obliquely installed between 11 and rear wall 12, so as to will the impact force from antetheca 11 from core plate 13 to rear wall 12 transmit when, can
To resolve into the vertical of the transverse component of the length direction along antetheca 11 and rear wall 12 and the surface of vertical front wall 11 and rear wall 12
To component, to further decrease impact force to the A column at the rear of vehicle body and the transmitting of crew module.
Also, the inclined direction of every two adjacent core plate 13 is on the contrary, in this way, above-mentioned generation transverse component again can be mutual
It offsets, to reduce the damage that the collision energy-absorbing device 10 is generated in the deformation of vehicle-body width direction, so that it is guaranteed that collision energy-absorbing fills
Set 10 length of wagon direction deformation energy-absorbing, sufficiently to reduce the transmitting of the impact force to A column and crew module.
Further, for above-described embodiment, the inclination arrangement in a symmetrical of every two adjacent core plate 13 makes its phase
It is identical to the tilt angle of antetheca 11 or rear wall 12.So as to the cross being completely counterbalanced by 12 length direction of antetheca 11 or rear wall
To component.
The tilt angle of core plate 13 is not more than 45 °, in a particular embodiment, sets 45 ° for the tilt angle of core plate 13.
Also, the inclined direction of every two adjacent interlayer 132 is on the contrary, can be further such that each interlayer 132 divides
Second component of solution is cancelled out each other absorption.Specifically, every two adjacent interlayer 132 is in tilted layout in a symmetrical, is pressed from both sides
The tilt angle of layer 132 is not more than 45 °, in this embodiment, sets 45 ° for the tilt angle of interlayer 132.
For the various embodiments described above, the section shape for the crumple chamber that interlayer 132 is formed in the gap between two outer layers 131
Shape is trapezoidal or sinusoidal waveform or rectangle.
