The bolt hole being fixedly connected with subframe.
The sheet metal thickness of described inner panel is 4.0-5.0mm, and yield strength scope is 150-200Mpa.
The outside plate of described front longitudinal extension is aluminum alloy sheet metal component, sheet metal thickness 3.0-3.5mm, and yield strength is
200-300Mpa。
The utility model has the advantage of：
1st, the utility model front longitudinal body has higher bending rigidity, can effectively avoid in automotive front collides
The too early bending of front longitudinal, irrational front longitudinal deformation pattern is avoided the occurrence of, have conquassation stable, bearing capacity is strong, and energy-absorbing fills
The characteristics of dividing, the vehicle body acceleration peak value in collision later stage can be effectively reduced, so as to reduce the injury that occupant is subject to.
2nd, the utility model front longitudinal extension has higher rigidity, the S-type plate in front longitudinal extension, front longitudinal extension
Section is provided with inner panel and outside plate, and cavity is formed with S templates, contributes to energy during buffering collision, in collision process substantially not
Deformation, effectively reduces crew module's intrusion volume, so as to reduce the injury that occupant is subject to.
3rd, the utility model uses aluminum alloy materials, and car body weight is alleviated while vehicle collision performance is improved, and fits
In being widely popularized.

Embodiment
The utility model is described in detail with specific embodiment below in conjunction with the accompanying drawings.
Embodiment 1
As shown in Figure 1 and Figure 2, this front rail structure includes front longitudinal body 1 and front longitudinal extension 2.As in Figure 3-5,
Front longitudinal body uses " day " font uiform section (100mm × 100mm) extrusion forming, its aluminum alloy materials yield strength scope
200Mpa-250Mpa, thickness range 2.8mm-3.2mm, it can be formed during front shock and stablize effective conquassation, and reduce collision rift
The vehicle body acceleration peak value of phase, so as to reduce the injury that occupant is subject to.Front longitudinal body bottom portion is provided with 12mm bolts hole 11 and 12,
Being available for bolt, this body side surface of front longitudinal is provided with 12mm bolts hole 13, is available for spiral shell by being fixedly connected respectively with front overhang and subframe
