Detailed description of the invention
Below with reference to the accompanying drawings the preferred embodiments of the present invention are described.
Please refer to shown in Fig. 1, the embodiment of the present invention one provides a kind of front side member rear portion to strengthen structure, comprise first crossbeam 1 and a pair second cross beam 2, wherein first crossbeam 1 is connected between the root 40 of left and right front side member 4, and be positioned at front panel 6(see Fig. 4) outside, between the root 40 that second cross beam 2 is connected to the front side member 4 of homonymy and A post 5.First crossbeam 1 is installed by the root 40 of welding with front side member 4, and second cross beam 2 is also installed with the root 40 of front side member 4 and A post 5 respectively by welding, and second cross beam 2 is also installed by bolt and A post 5.Second cross beam 2 is positioned at inside front panel 6.
Structure is strengthened by above-mentioned front side member rear portion, because first crossbeam 1 is arranged between the root 40 of left and right front side member 4, thus make first crossbeam 1 be positioned at impact force delivery areas, be equivalent to the transmission channels constructing an impact force between the front side member of left and right, as shown by the arrows in Figure 2, when head-on crash occurs, impact force is transmitted backward from front side member 4, first crossbeam 1 and second cross beam 2 effectively can resist impact force, and make impact force be diffused into whole body shell along first crossbeam 1 and second cross beam 2 respectively, reduce front panel 6 intrusion volume.In addition, first crossbeam 1 is positioned at outside front panel 6, namely first crossbeam 1 is in outside crew module, front side member-first crossbeam-front panel from outside to inside, therefore the first crossbeam 1 that the present embodiment is arranged does not take crew module space, can not impact the layout of the air-conditioning in crew module, pedal, steering column.
Please more simultaneously with reference to shown in Fig. 3, Fig. 4, in order to strengthen the effect of resisting and disperseing impact force further, the present embodiment is also provided with a pair the 3rd crossbeams 3, between the root 40 being connected to the front side member 4 of homonymy and A post 5, and stacked formation closed cross-section mutual to second cross beam 2.Particularly, the 3rd crossbeam 3 is installed with the root 40 of front side member 4 and A post 5 respectively by welding, and the 3rd crossbeam 3 is also installed by bolt and A post 5.3rd crossbeam 3 is welded to connect at root 40 place of front side member 4 and first crossbeam 1.3rd crossbeam 3 is positioned at outside front panel 6.
The setting of the 3rd crossbeam 3, further enhancing the effect of resisting and disperseing impact force, and is positioned at outside front panel due to it, will effectively reduce front panel 6 intrusion volume, and also play booster action to second cross beam 2.
Please refer to shown in Fig. 5, structure is strengthened at the front side member rear portion corresponding to the embodiment of the present invention one, and the embodiment of the present invention two provides a kind of front side member rear portion to strengthen the manufacture method of structure, comprising:
Step S1, provides first crossbeam 1 and a pair second cross beam 2 respectively;
Step S2, welds first crossbeam 1 and second cross beam 2 with front panel 6 respectively;
Step S3, between the root 40 first crossbeam 1 being connected to left and right front side member 4;
Step S4, between the root 40 second cross beam 2 being connected to the front side member 4 of homonymy and A post 5.
Wherein, in step S2, first crossbeam 1 is positioned at outside front panel 6, and second cross beam 2 is positioned within front panel 6.Dividing of sequencing is there is no between step S3, S4.Particularly, first crossbeam 1 is installed by welding and front side member 4, and second cross beam 2 is also installed with front side member 4 and A post 5 respectively by welding, and second cross beam 2 is also installed by bolt and A post 5.
Because first crossbeam 1 is arranged between the root 40 of left and right front side member 4, thus make first crossbeam 1 be positioned at impact force delivery areas, be equivalent to the transmission channels constructing an impact force between the front side member of left and right, as shown by the arrows in Figure 2, when head-on crash occurs, impact force is transmitted backward from front side member 4, first crossbeam 1 and second cross beam 2 effectively can resist impact force, and make impact force be diffused into whole body shell along first crossbeam 1 and second cross beam 2 respectively, reduce front panel 6 intrusion volume.In addition, first crossbeam 1 is positioned at outside front panel 6, namely first crossbeam 1 is in outside crew module, front side member-first crossbeam-front panel from outside to inside, therefore the first crossbeam 1 that the present embodiment is arranged does not take crew module space, can not impact the layout of the air-conditioning in crew module, pedal, steering column.
In order to strengthen the effect of resisting and disperseing impact force further, the present embodiment also comprises in step sl:
A pair the 3rd crossbeams 3 are provided;
Thus, before step S2, also comprise:
3rd crossbeam 3 is welded on first crossbeam 1 two ends respectively.
Step S2 also comprises:
3rd crossbeam 3 is mutually stacked with second cross beam 2 respectively and weld, form closed cross-section.
Step S4 is specially: between the root 40 that mutually stacked second cross beam 2 and the 3rd crossbeam 3 are connected to the front side member 4 of homonymy and A post 5.
Particularly, the 3rd crossbeam 3 is installed with front side member 4 and A post 5 respectively by welding, and the 3rd crossbeam 3 is also installed by bolt and A post 5.3rd crossbeam 3 is welded to connect at root 40 place of front side member 4 and first crossbeam 1.3rd crossbeam 3 is positioned at outside front panel 6.
The setting of the 3rd crossbeam 3, further enhancing the effect of resisting and disperseing impact force, and is positioned at outside front panel 6 due to it, will effectively reduce front panel 6 intrusion volume, and also play booster action to second cross beam 2.
Above disclosedly be only present pre-ferred embodiments, certainly can not limit the interest field of the present invention with this, therefore according to the equivalent variations that the claims in the present invention are done, still belong to the scope that the present invention is contained.
