Specific embodiment
It is with reference to the accompanying drawings and embodiments, right in order to which the objects, technical solutions and advantages of the application are more clearly understood
The application is further elaborated.It should be appreciated that specific embodiment described herein is only used to explain the application, and
It is not used in restriction the application.
As shown in Figure 1 and Figure 2, embodiments herein discloses a kind of front rail structure of vehicle, and one end of front longitudinal beam is used
It is connect in energy-absorption box, the other end of front longitudinal beam with front side wall for connecting.The front rail structure includes inner panel 1, outside plate 2 and folding
Curved guiding groove 3.Inner panel 1 and outside plate 2 connect, and are formed with the first cavity, bending guiding groove 3 is set on inner panel 1 and outside plate 2, i.e.,
It is set on the side wall of first cavity.When automobile occur high velocity impact when, by bending guiding groove 3 guide the front longitudinal beam according to
Preset deformation pattern carries out bending energy-absorbing, and the acceleration impact of collision is effectively reduced.
As shown in Figure 3, Figure 4, which further includes reinforcer 4, and inner panel 1 is provided with convex close to one end of energy-absorption box
Muscle 12.Bending guiding groove 3 includes the first groove 31, the second groove 32, third groove 33 and the 4th groove 34.First groove 31 is set
It is placed in one end on inner panel 1 close to front side wall, the 4th groove 34 is set to one end on inner panel 1 close to energy-absorption box.Second groove
32 are set on outside plate 2 and are located at outside plate 2 close to the side of front side wall, and third groove 33 is set on outside plate 2 and is located at outside plate 2
Close to one end of energy-absorption box.When assembling, reinforcer 4 is fixedly connected by way of spot welding with outside plate 2, is formed with the second chamber
