Fig. 3 is the perspective view for indicating an example of vehicle body structure 100.Inboard curb girder 1 is shown in FIG. 3, omits
The nearby half of the nearby side in the curb girder 1, crossbeam 4 of side, the first strengthening part 2 and being arranged on the curb girder 1 of nearby side
Two strengthening parts 3 and indicate.
As shown in Figures 2 and 3, vehicle body structure 100 has: curb girder 1, the first strengthening part 2, the second strengthening part
3 and crossbeam 4.
As shown in Figures 2 and 3, curb girder 1 extends in vehicle front-rear direction (Y-direction).Curb girder 1 is with upper flange part
11, lower flange portion 12 and wall portion 13, component that section is C font.A pair of of curb girder 1 is configured in the vehicle-width direction (side X
To) on be separated from each other it is opposed.Wall portion 13 in the rear end 1a of curb girder 1 has (will along the inclination of the first fixed part 22
Give aftermentioned) upper edge 14.
Fig. 4 is the line A-A sectional view of Fig. 3.
As shown in Figure 3 and Figure 4, the first strengthening part 2 includes the first fixed part 22, front side flange part 24, convex on the outside of front
Edge 26 and trailing outside flange part 28.
As shown in figure 4, the first fixed part 22 is from vehicle lower side end 23a to vehicle upper side end 23 to vehicle front direction (+Y
Direction) inclination.First fixed part 22 is set to, in the connection operation of tractor and trailer, the height that can be abutted with trailer
Position.
Front side flange part 24 is set to the vehicle front side (+Y direction) of the first fixed part 22, along the rear end of curb girder 1
The mode of upper flange part 11 in 1a is arranged.
Front outboard flanges portion 26 is set on the outside of the vehicle-width direction of front side flange part 24 (+X direction), passes through bolt
Or rivet is fixed on the wall portion 13 in the rear end 1a of curb girder 1 (referring to Fig. 2).
Trailing outside flange part 28 is set on the outside of the vehicle-width direction of the first fixed part 22 (+X direction), passes through bolt
Or rivet is fixed on the wall portion 13 in the rear end 1a of curb girder 1 (referring to Fig. 2).
Second strengthening part 3 has the second fixed part 32 and outboard flanges portion 34.
Second fixed part 32 extends in vehicle front-rear direction (Y-direction).
The wall portion 13 in the rear end 1a of curb girder 1 is fixed in outboard flanges portion 34 by bolt or rivet (referring to Fig. 2).
As shown in Figure 2 and Figure 4, crossbeam 4 extends in vehicle-width direction (X-direction).Crossbeam 4 be with upper wall portions 41,
Lower wall portion 42 and standing wall portion 43, component that section is U-shaped.Standing wall portion 43 is upwardly extended in vehicle upper and lower.Upper wall portions 41
From the upper end in the vehicle up and down direction (Z-direction) of standing wall portion 43 to vehicle up direction direction and vehicle front direction extends.Under
Wall portion 42 extends from the lower end in the vehicle up and down direction of standing wall portion 43 to vehicle front direction.
Both ends 41a on the vehicle-width direction of upper wall portions 41 is fixed along the first fixed part 22 by bolt or rivet
(referring to Fig. 2).Central portion 41b in the vehicle width direction of upper wall portions 41 have from vehicle lower side end 45a to vehicle upper side end 45 to
The inclined rake 46 in vehicle front direction (+Y direction) (referring to Fig. 4).
Both ends 42a on the vehicle-width direction of lower wall portion 42 is fixed on the by bolt or rivet (equal illustration omitted)
Two fixed parts 32.
Then, the effect of vehicle body structure 100 is illustrated.
In the connection operation of tractor and trailer, in the feelings that trailer is abutted with the first fixed part 22 (rear end of tractor)
Under condition, the first fixed part 22 is tilted to vehicle front direction, therefore trailer is moved along the upper surface of the first fixed part 22.It collides
When the kinetic energy of trailer be converted predominantly into: kinetic energy when trailer is moved along the upper surface of the first fixed part 22 passes through trailer
The strain energy of thermal energy and the first fixed part 22 that friction between the first fixed part 22 generates.Therefore, can make trailer with
Impact dispersion when first fixed part 22 abuts.
In addition, the upper wall portions 41 of crossbeam 4 are fixed along the first fixed part 22.Rushing when thereby, it is possible to make to abut with trailer
It hits and is dispersed to 4 side of crossbeam.
Also, the lower wall portion 42 of crossbeam 4 is fixed on curb girder 1 by the second strengthening part 3.Thereby, it is possible to make to support with trailer
Impact when connecing is dispersed to 1 side of curb girder from 4 side of crossbeam by the second strengthening part 3.
<effect of present embodiment>
As described above, vehicle body structure 100 according to the present embodiment, the first fixed part 22 is to vehicle front direction
Inclination.Impact dispersion as a result, in the connection operation of tractor and trailer, when can make to abut with trailer are as follows: after collision
The kinetic energy of the trailer moved along the upper surface of the first fixed part 22 is generated by the friction between trailer and the first fixed part 22
Thermal energy etc..In addition, the upper wall portions 41 of crossbeam 4 are fixed along the first fixed part 22.Thereby, it is possible to so that impact is dispersed to crossbeam 4
Side.
In addition, the central portion 41b in the vehicle width direction of upper wall portions 41 has from vehicle lower side end 45a to vehicle upper side end 45
To the inclined rake 46 in vehicle front direction.As a result, in the case that when trailer links, trailer is abutted with rake 46, punching
The kinetic energy of trailer when hitting is also translated into: kinetic energy when trailer is moved along the upper surface of rake 46, by trailer with incline
The strain energy of thermal energy and rake 46 that friction between inclined portion 46 generates.Therefore, impact when can make to abut with trailer
Dispersion.
It should be noted that the inclination of the first fixed part 22 of above embodiment is the setting from the 23a of vehicle lower side end, but
The invention is not limited thereto, as long as being arranged from the middle part (vehicle lower side) between vehicle lower side end 23a and vehicle upper side end 23
?.But the middle part is set in than the height and position that can abut in tractor and trailer when the connection operation of trailer more
By the position of vehicle lower side.
In addition, in the above-described embodiment, upper wall portions 41 from the upper end of standing wall portion 43 to vehicle up direction to and vehicle before
Fang Fangxiang extends, and lower wall portion 42 extends from the lower end of standing wall portion 43 to vehicle front direction.But the invention is not limited thereto,
Or upper wall portions 41 extend from the upper end of standing wall portion 43 to vehicle lower section direction and rear of vehicle direction, and lower wall portion 42
Extend from the lower end of standing wall portion 43 to rear of vehicle direction.In this case, two on the vehicle-width direction of upper wall portions 41
End is fixed along the first fixed part 22.
The application is existed based on the Japanese patent application (Patent 2017-033803) proposed on 2 24th, 2017, content
This is introduced as reference.
