Embodiment
Below with reference to the accompanying drawings the preferred embodiments of the present invention are described.
It refer to shown in Fig. 1, the embodiment of the present invention one provides a kind of front longitudinal rear portion reinforcement structure, including first crossbeam 1
With a pair of second cross beams 2, wherein first crossbeam 1 is connected between the root 40 of left and right front longitudinal 4, and positioned at front panel 6（Ginseng
See Fig. 4）Outside, second cross beam 2 is connected between the root 40 of the front longitudinal 4 of homonymy and A posts 5.First crossbeam 1 passes through weldering
The root 40 connect with front longitudinal 4 is installed, and second cross beam 2 is installed with the root 40 of front longitudinal 4 and A posts 5 respectively also by welding, and
And second cross beam 2 can also be installed by bolt with A posts 5.Second cross beam 2 is located at the inner side of front panel 6.
By above-mentioned front longitudinal rear portion reinforcement structure, because first crossbeam 1 is arranged on the root 40 of left and right front longitudinal 4
Between, so that first crossbeam 1 is located at impact force delivery areas, equivalent to constructing an impact force between the front longitudinal of left and right
Transmission channels, as shown by the arrows in Figure 2, when head-on crash occurs, impact force is transmitted backward from front longitudinal 4, first crossbeam 1
Impact force can be effectively resisted with second cross beam 2, and it is whole impact force is diffused into respectively along first crossbeam 1 and second cross beam 2
Individual body shell, reduces the intrusion volume of front panel 6.It is in and multiplies in addition, first crossbeam 1 is located at the outside of front panel 6, i.e. first crossbeam 1
It is front longitudinal-first crossbeam-front panel from outside to inside outside member cabin, therefore the first crossbeam 1 that the present embodiment is set is not take up multiplying
Member cabin space, will not be impacted to the arrangement of the air-conditioning in crew module, pedal, steering column.
Please again referring concurrently to shown in Fig. 3, Fig. 4, in order to further enhance the effect of resistance and scattered impact force, the present embodiment
A pair of the 3rd crossbeams 3 are also provided with, are connected between the root 40 of the front longitudinal 4 of homonymy and A posts 5, with the phase of second cross beam 2
It is mutually stacked to form closed cross-section.Specifically, the 3rd crossbeam 3 is installed with the root 40 of front longitudinal 4 and A posts 5 respectively by welding, and
And the 3rd crossbeam 3 can also be installed by bolt with A posts 5.3rd crossbeam 3 is welded at the root 40 of front longitudinal 4 with first crossbeam 1
Connection.3rd crossbeam 3 is located at the outside of front panel 6.
The setting of 3rd crossbeam 3, further enhancing the effect of resistance and scattered impact force, and because it is located at front wall
Outside plate, the intrusion volume of front panel 6 will be effectively reduced, booster action is also functioned to second cross beam 2.
It refer to shown in Fig. 5, corresponding to the front longitudinal rear portion reinforcement structure of the embodiment of the present invention one, the embodiment of the present invention two
A kind of manufacture method of front longitudinal rear portion reinforcement structure is provided, including：
Step S1, provides first crossbeam 1 and a pair of second cross beams 2 respectively；
Step S2, respectively welds first crossbeam 1 and second cross beam 2 with front panel 6；
Between step S3, the root 40 that first crossbeam 1 is connected to left and right front longitudinal 4；
Step S4, second cross beam 2 is connected between the root 40 of the front longitudinal 4 of homonymy and A posts 5.
Wherein, first crossbeam 1 is located at outside front panel 6 in step S2, and second cross beam 2 is located within front panel 6.Step
Point of sequencing is had no between S3, S4.Specifically, first crossbeam 1 is installed by welding with front longitudinal 4, and second cross beam 2 also leads to
Welding is crossed to install with front longitudinal 4 and A posts 5 respectively, and second cross beam 2 can also be installed by bolt with A posts 5.
Between the root 40 that left and right front longitudinal 4 is arranged on due to first crossbeam 1, so that first crossbeam 1 is located at impact force
Delivery areas, equivalent to the transmission channels that an impact force is constructed between the front longitudinal of left and right, as shown by the arrows in Figure 2, when
When head-on crash occurs, impact force is transmitted backward from front longitudinal 4, and first crossbeam 1 and second cross beam 2 can effectively resist collision
Power, and impact force is diffused into whole body shell along first crossbeam 1 and second cross beam 2 respectively, reduce front panel 6 and invade
Amount.Be in addition, first crossbeam 1 is located at the outside of front panel 6, i.e. first crossbeam 1 outside crew module, be from outside to inside front longitudinal-
First crossbeam-front panel, therefore the first crossbeam 1 that the present embodiment is set is not take up crew module space, will not be in crew module
Air-conditioning, pedal, the arrangement of steering column are impacted.
In order to further enhance the effect of resistance and scattered impact force, the present embodiment also includes in step sl：
A pair of the 3rd crossbeams 3 are provided；
Thus, before step S2, in addition to：
3rd crossbeam 3 is respectively welded at the two ends of first crossbeam 1.
Step S2 also includes：
3rd crossbeam 3 is superposed and weld with second cross beam 2 respectively, form closed cross-section.
Step S4 is specially：The superposed crossbeam 3 of second cross beam 2 and the 3rd is connected to the front longitudinal 4 of homonymy
Root 40 and A posts 5 between.
Specifically, the 3rd crossbeam 3 is installed with front longitudinal 4 and A posts 5 respectively by welding, and the 3rd crossbeam 3 can also pass through
Bolt is installed with A posts 5.3rd crossbeam 3 is welded to connect at the root 40 of front longitudinal 4 with first crossbeam 1.3rd crossbeam 3 is located at
The outside of front panel 6.
The setting of 3rd crossbeam 3, further enhancing the effect of resistance and scattered impact force, and because it is located at front wall
Outside plate 6, the intrusion volume of front panel 6 will be effectively reduced, booster action is also functioned to second cross beam 2.
Above disclosure is only preferred embodiment of present invention, can not limit the right model of the present invention with this certainly
Enclose, therefore the equivalent variations made according to the claims in the present invention, still belong to the scope that the present invention is covered.
