The specific embodiment
Below, embodiments of the present invention will be described in detail with reference to the accompanying drawings.Fig. 1 is the block diagram of the front body structure of vehicle according to an embodiment of the invention, and Fig. 2 is the block diagram of seeing from the car body rear of the A portion of Fig. 1, Fig. 3 be the B-B of Fig. 2 to looking section drawing, Fig. 4 is that the C-C of Fig. 2 is to looking section drawing.Upper and lower, the front, rear, left and right of car body are represented in upper and lower, front, rear, left and right in the accompanying drawing.
Fig. 1 is the front portion of expression car body 1, and vehicle body 2 is set on top, and the vehicle frame 3 of this vehicle body 2 of supporting is set in the bottom.
The cross section of front end cross beam 4 forms roughly コ font (grooved), forms flange part 4a (with reference to Fig. 3) at edge part.And the open side that makes this cross section that is roughly the コ font is towards the setting of car body rear extension.Head lamp stay bearing plate 5 extends setting along the overall width direction, and is connected with the two side ends back of front end cross beam 4, and the top of left and right sides head lamp stay bearing plate is connected by the upper front end bar 6 as strengthening part.Mudwing 7 extends along the car body fore-and-aft direction at the rear of front end cross beam 4 and is provided with, and its front end face 7a (with reference to Fig. 3) and front end cross beam 4 and head lamp stay bearing plate 5 are overlapped and be connected.
On the other hand, vehicle frame 3 extend to be provided with along the car body fore-and-aft direction, and its left and right sides is provided with mounting bracket 8 (about in Fig. 1 each).This mounting bracket 8 is provided with the body support 9 as the elastomeric element of supporting vehicle body 2.And vehicle body 2 is arranged at body support 9.That is, vehicle frame 3 is by body support 9 supporting vehicle bodies 2.
To shown in Figure 4, head lamp stay bearing plate 5 and mudwing 7 are connected on the top of the front end face 7a of the top, back of the car body fore-and-aft direction of head lamp stay bearing plate 5 and mudwing 7 as Fig. 2.And, in the overall width direction outside of this connecting portion, for being connected with pillar 10 across head lamp stay bearing plate 5 and mudwing 7 formation closed sections.
That is, flange part 10c is connected in mudwing 7, simultaneously, flange part 10e is connected in head lamp stay bearing plate 5, thereby make car body fore-and-aft direction or overall width direction form closed section.In addition, flange part 10b is connected in upper front end bar 6, simultaneously, flange part 10d is connected in the bight of head lamp stay bearing plate 5 and mudwing 7 and it is coincide, thereby form closed section at the car body above-below direction.Therefore, can strengthen the Joint strenght of the connecting portion between head lamp stay bearing plate 5 and the mudwing 7, and can improve rigidity.
When vehicle ' during, apply the load of car body above-below direction or left and right directions to vehicle frame 3 from wheel (omitting diagram) here, in the abominable road of detour or road conditions etc.And the load that applies to this vehicle frame 3 is delivered to parts such as front end cross beam 4, head lamp stay bearing plate 5 and mudwing 7 by body support 9.
In the structure of present embodiment,, improve the intensity of connecting portion by overall width direction arranged outside pillar 10 at the connecting portion of head lamp stay bearing plate 5 and mudwing 7, and enhancing rigidity, therefore, even to head lamp stay bearing plate 5 applied loads, also bearing load effectively.Wherein, above-mentioned pillar 10 forms closed section across head lamp stay bearing plate 5 and mudwing 7, and, comprise longitudinal wall part 10a and flange part 10b～flange part 10e, and be connected in head lamp stay bearing plate 5, upper front end bar 6 and mudwing 7 with this flange part 10b～flange part 10e.
As mentioned above,, can improve the rigidity of car body 1 because pillar 10 is set, and, because pillar 10 is small and light strengthening parts, can not increase the weight of car body 1.And, owing to improved rigidity, when needs Joint strenght identical and rigidity, compared with prior art, can make the thickness of slab of head lamp stay bearing plate 5 thinner with prior art, therefore can realize car body 1 lightweight.
Therefore, the front body structure according to vehicle involved in the present invention comprises: head lamp stay bearing plate 5 is arranged on the both sides of the overall width direction of car body 1 front end; Mudwing 7, its front end face 7a is connected in above-mentioned head lamp stay bearing plate 5, and extends setting along the car body fore-and-aft direction; Upper front end bar 6 is arranged on the upper limb of above-mentioned head lamp stay bearing plate 5, and extends along the overall width direction and to be provided with; And pillar 10, on the connecting portion in the overall width direction outside of the connecting portion on the front end face 7a top of the top, back of the car body fore-and-aft direction of above-mentioned head lamp stay bearing plate 5 and above-mentioned mudwing 7, for forming closed section, also be connected with above-mentioned mudwing 7 across above-mentioned head lamp stay bearing plate 5.Thus, the Joint strenght of connecting portion can be improved, thereby the rigidity of car body 1 can be improved.And, can make the thickness of slab attenuation of head lamp stay bearing plate 5 according to the degree of the rigidity that improves car body 1, so, can realize the lightweight of car body 1.
And pillar 10 extends setting along the car body above-below direction, and flange part 10b is connected in upper front end bar 6, across head lamp stay bearing plate 5 and mudwing 7 10d of flange connector portion, thereby makes the car body above-below direction also form closed section, therefore, can further improve rigidity.And, can make the thickness of slab attenuation of head lamp stay bearing plate 5 according to the degree of the rigidity that improves car body 1, so, can realize the lightweight of car body 1.
