Specific embodiment
Further to illustrate that the utility model is to reach the technological means and effect that predetermined purpose of utility model taken,
Below in conjunction with attached drawing and preferred embodiment, to the utility model, detailed description are as follows.
As depicted in figs. 1 and 2, the energy-absorption box front end ruggedized construction of an embodiment provided by the utility model, including preceding anti-
Hit beam 10, energy-absorption box 20, end plate 30 and securing plate 40.Energy-absorption box 20 be fixedly connected on front anti-collision beam 10 and end plate 30 it
Between, energy-absorption box 20 includes side plate 201, and 40 one end of securing plate is fixedly connected on front anti-collision beam 10, and the other end is fixedly connected on energy-absorbing
The side plate 201 of box.Specifically, seam weld mode is preferentially selected between anticollision front-axle beam 10, energy-absorption box 20, end plate 30 and securing plate 40
It is fixed.
The utility model has greatly reinforced energy-absorbing by adding fixed plate 40 in front anti-collision beam 10 and 20 junction of energy-absorption box
The bonding strength of box 20 and front anti-collision beam 10, avoids 20 front end of energy-absorption box cracking, ensures that power transmits stability, greatly carries
High body construction security performance.
Front anti-collision beam 10 is the crossbeam for having certain radian, and two energy-absorption boxes 20 are respectively positioned at the two of the side of front anti-collision beam 10
End.
Front anti-collision beam 10 includes the first cavity 101 and partition board 102, and 101 number of the first cavity is multiple and is laid in preceding anti-
It hits inside beam 10, the first cavity 101 is by the partition board 102 inside front anti-collision beam 10 every setting.It is preceding when front high velocity impact
Preferentially deformation absorbs part energy to collision prevention girders 10, alleviates the stress of end plate 30 and body of a motor car indirectly.
Energy-absorption box 20 is internal cavity structures.Specifically in the present embodiment, energy-absorption box 20 includes four end to end sides
Plate 201.
Multiple first through hole 203 are offered on the side plate 201 of energy-absorption box 20.When head-on crash, due to energy-absorption box 20
Inside is equipped with multiple first through hole 203 for cavity structure and its surface so that energy-absorption box 20 can deform in time, and quick absorb is touched
Hit energy.
In the present embodiment, the better aluminum alloy materials energy-absorption box of 20 preferred properties of energy-absorption box.In other embodiments, energy-absorbing
Box 20 can also be Metal plate or other materials.
Securing plate 40 is tablet, and securing plate 40 is obliquely installed with respect to the side plate 201 and front anti-collision beam 10 of energy-absorption box 20.
In the present embodiment, securing plate 40 is connected on the side plate 201 for the side that two energy-absorption boxes 20 are located remotely from each other.It can manage
Solution, securing plate 40 are also connected to other side plates 201 of energy-absorption box 20.
The distance of securing plate 40 both ends to the two sides of side plate 201 is identical.Since securing plate 40 is located at energy-absorption box side plate 201
Middle part so that securing plate 40 to collision when be transmitted to the transmission force property of 10 junction of energy-absorption box side plate 201 and front anti-collision beam more
Stablize.
As shown in figure 3, offering the second through-hole 401 in securing plate 40, the second through-hole 401 is distributed in securing plate 40.This
In embodiment, specifically, the second through-hole is two, and two the second through-holes 401 are symmetrically distributed in securing plate 40.In other realities
