Description
Technical field
The present invention relates to a vehicle body structure.
Background technology
Be used to provide a leading flank element (side member of the leading portion of a vehicle body) and have a kind of impact absorption ability and be used to provide develop the safety performance when colliding to improve around various technology that have the body portion of rigidity in the cabin that a passenger takes.More particularly, the collision of leading flank element is similar to an accordion in the collision, applies thereon impact with absorption, and it ought to transfer to vehicle cabin, and the safety in cabin is improved.
Herein, provide a body structure, have two conflicting like this functions, an impact absorption function and a shock-resistant function are important tasks to be solved.
Consider this point, patent publications Japanese Patent PublicationNo.2000-153779 shown in Figure 8 discloses a leading flank element 121, and it comprises: a leading portion 121a, and on even keel extends to the front and back of vehicle on lateral plan; A sweep 121b forwardly divides the back of 121a, and sweep 121b is downwards crooked; A trailing portion 121c is in the back of sweep 121b, the bending of trailing portion 121c on even keel.The rear end of the leading portion 121a of leading flank element 121 engages with an instrument carrier panel reinforcement 123, and it extends on the Width of the vehicle body between right and the left front column 122, by a buffering crossbeam 128 and a column stay 140.Distinguishingly, a joint between buffering crossbeam 128 and leading flank element 121, the leading portion 121a and the sweep 121b of leading flank element 121 have the shape of cross section that differs from one another, thereby the rear end of forwardly dividing 121a forms a step in vertical direction, and buffering crossbeam 128 is engaged to the vertical side of step.
Use this kind arrangement, during collision, an impulsive force F who is applied to leading flank element 121 from fwd is not only absorbed by the leading portion 121a of leading flank element 121, but also be dispensed to sweep 121b, A-pillar 122 and the instrument carrier panel reinforcement 123 of leading flank element 121, and will prevent like this in the body portion distortion of these element back or around the vehicle cabin distortion.
According to Japanese Patent publication No.2000-153779, thereby the leading portion 121a of leading flank element 121 has different shape of cross section (or rather, the cross-sectional plane of leading portion 121a is greater than the cross-sectional plane of sweep 121b) with sweep 121b makes and cushion the rear end that vertical surface that crossbeam 128 engages is formed on leading portion 121a.
Yet this structure has following problem.If the trailing portion 121c of leading flank element 121 has a bigger cross-sectional plane, it can stand a stronger impact, the vertical surface that engages with the buffering crossbeam also needs bigger, with the rigidity of balance around vehicle cabin, and leading portion 121a finally must have a very large cross-sectional plane.Make the leading portion 121a opposing of leading flank element 121 less like this, thereby influence absorb impulsive force F by the flattening property of the impulsive force that applies previously.
Moreover, in order to reduce the size with the vertical surface that engages of buffering crossbeam 128, it is contemplated that the leading portion 121a that makes column stay 140 and leading flank element 121 arranges with the angle θ 1 that forms an increase between them, to be reduced to the load input of column stay 140.Yet, will influence distribution like this at the leading portion 121a place of leading flank element 121 impulsive force.And, if leading portion 121a is given small cross section, impulsive force F is absorbed effectively by leading flank element 121, the size of the vertical surface that engages with buffering crossbeam 128 also must be less.As a result, leading flank element 121 reduces as a whole rigidity and intensity, thereby bending of Z-shape and fold may be produced, and no longer can guarantee around the rigidity and the intensity of vehicle cabin.
As previously discussed, patent application 1 is to be accompanied by problem, and its very difficult shape of cross section with definite structural constituent makes their impact absorption ability improve like this, and avoids effectively around the distortion in cabin.
Moreover, in patent application 1, as shown in Figure 8, to leading flank element 121 transfer to A-pillar 122 from fwd impact load F by column stay 140, column stay 140 is to use a column bolt or similar bolted to cushioning the rear end of crossbeam 128 at the leading portion 121a of leading flank element 121.
Herein, buffering crossbeam 128 can have the rectangle that a shape of cross section is different from Fig. 8: for example, and circle, hexagon and octagon.In these cases, use a column bolt or similar bolt to be difficult to directly fastening buffering crossbeam 128 to leading flank element 121 and column stay 140.

Leading flank element 1 as shown in Figure 1 and Figure 4, has a leading portion 1a, on even keel extends on the length direction of vehicle, one first sweep 1d forwardly divides the location bending of back of 1a downward, a centre portion 1b is tilted to the rear at one and is upwards extended downwards by sweep, one second sweep 1e is crooked once more in a position of the back of centre portion 1b in the horizontal direction, and a trailing portion 1c is extended by the second sweep 1e on even keel on direction backward.
Moreover leading flank element 1 has an osed top cross-sectional plane, as shown in Figure 7.Leading flank element 1 has pair of sidewalls (element sidewall) 1h and 1h, along the length and the short transverse shaping of vehicle body; Flange 1g and 1g, they are that the top of sidewall 1h is bending; A bottom 1i, it is enclosed in the opening between the lower end of sidewall 1h and 1h; And a top surface 1k, it is enclosed in the opening between the upper end of sidewall 1h and 1h.
Flange 1g and 1g, sidewall 1h and 1h and bottom 1i and 1i, they are to use near the steel plate element of the extrusion production of U-shape to make, and are to be configured as one, and top surface 1k is flange 1g and the 1g that is spot welded to two sides, thereby form an osed top cross-sectional plane.The thickness of the steel plate element of the independent part of composition leading flank depends on their positions in cross-sectional plane.
Herein, as shown in Figure 5, this embodiment uses a crushable structure, so, when collision of the front portion of vehicle, if impact load F is a leading portion by leading flank element 1 be applied to leading flank element 1 (Here it is by vehicle forwards to), the leading portion 1a of leading flank element 1 flattens becomes an accordion shape, thereby absorb this load, therefore, the centre portion 1b and the trailing portion 1c of leading flank element 1 are fabricated to thicker than leading portion 1a.
As shown in Figure 1, a buffering wallboard 4 is set on leading flank element 1, it comprises front panel (vertical wall) 4a and a ground wallboard 4b.Front panel 4a on the width of vehicle body and the short transverse by the first sweep 1d of leading flank element 1 near extension; Ground wallboard 4b is tilted to down near the rear portion by first sweep 1d extension.The cabin of buffering wallboard 4 dividing vehicles and its engine room.
As shown in Figure 1, provide a buffering crossbeam 3 here, extend on the Width on leading flank element 1.Buffering crossbeam 3 extends to the leading flank element 1 on the left side by the left end of on-deck crossbeam 7, and between two leading flank elements 1 and 1 of two sides, and the right-hand member that extends to on-deck crossbeam 7 by the leading flank element 1 on the right fully.
Front rack (one of two types of supporting members; The first supporting member part) 2 and 2, and tail-bracket (another of two types of supporting members; The second supporting member part) 6 and 6, be arranged on the front (on the length direction of vehicle body) of A-pillar 8 and 8, and buffering crossbeam 3 is the upper surfaces that are connected to leading flank element 1 and 1; In column 8 and 8 fwd positions.
Use this arrangement, as shown in Figure 1, buffering crossbeam 3 and on-deck crossbeam 7 are combined to form a framed structure that has trapezoidal (rectangle).This framed structure forms in one plane, and it tilts with respect to the length direction of vehicle body, thereby realizes a body structure closely.Therefore,, transferred to on-deck crossbeam 7 and A-pillar 8 reliably, thereby make distortion (Here it is bending of Z-shape and fold) to the load that applies of buffering crossbeam 3 by leading flank element 1, breaking such as leading flank element 1 enters vehicle cabin and can avoid.
Two front racks 2 and the 2 leading flank elements 1 and 1 that are fixed on the two sides are of similar shape and identical structure, and therefore, the following description will be in two any one, unless indication is arranged in addition.Treat equally for a pair of tail- bracket 6 and 6, so the following description will be in two any one, unless indication is arranged in addition.
Tail-bracket 6 as shown in Figure 4, be to be fixed to leading flank element 1 is right after the back at the vertical wall 4a of buffering wallboard 4 a position, and also be fixed to leading flank element 1 near the first sweep 1d, can transfer to buffering crossbeam 3 effectively by the load that applies previously herein, and the ground wallboard 4b of buffering wallboard 4 is interposed between them.
And shown in Fig. 3 and Fig. 6 (a), tail-bracket 6 has a pair of second sidewall 6a and the 6a, one second upstanding portion 6b and a bottom surface portions 6c.Second sidewall (a pair of supporting member sidewall) 6a and 6a are shaped along the length direction of leading flank element 1, and are arranged as a standing state along the length and the short transverse of vehicle body; The second upstanding portion 6b connects the front end of the second sidewall 6a and 6a, and extends on the width of vehicle body and short transverse, to keep flat the width of crossing leading flank element 1; Bottom surface portions 6c connects the bottom end of sidewall 6a and 6a, and the bottom surface that forms tail-bracket 6.
Moreover the sidewall 6a and the 6a of tail-bracket 6 have holder part 6d and 6d, are used for keeping buffering crossbeam 3.This holder part 6d and 6d are made for the part in hole, and its periphery is identical with the size and dimension of the cross-sectional perimeter of buffering crossbeam 3.Buffering crossbeam 3 thereby is kept with a kind of stable manner by tail-bracket 6, and the periphery that cushions crossbeam 3 is contacted with 6d with entire bracket part 6d.
As shown in figures 1 and 3, provide front rack (first carriage) 2 and 2 here on the upper surface of leading flank element 1. Front rack 2 and 2 is near the back (Here it is, the first sweep 1d) that are positioned at the previous section 1a of leading flank element 1 but is right after in the front of cushioning wallboard 4.
This front rack 2, shown in Fig. 2 and Fig. 6 (b), mainly comprise a pair of the first side wall (a pair of supporting member sidewall) 2a and 2a, they are to be shaped along the length of leading flank element 1 and short transverse, to extend upwards, and one first upstanding portion 2b, it connects the rear end of the first side wall 2a and 2a, and extends on the width of vehicle body and short transverse.Front rack 2 has the shape of a right-angled triangle in the lateral plan of Fig. 4.Herein, front rack 2 is not often to have so shape of strict right-angled triangle, and some other approaching triangle also can use.
As a result, first upstanding portion 2b of front rack 2 and the second upstanding portion 6b of tail-bracket 6 are fixed to one another, thereby make load transfer to tail-bracket 6 reliably by front rack 2.In addition, front rack 2 and tail-bracket 6 are fixed to one another, and buffering wallboard 4 is interposed between them, thereby it is fastening to make buffering wallboard 4 be stabilized ground.
In the lower end of the first side wall 2a and 2a, form flange 2c and 2c here, they are ends of sidewall 2a, outwardly-bent by press forming by vehicle body, these flanges 2c and 2c, and the flange 1g of leading flank element 1 and 1g be spot welded each other, is to be fixed to leading flank element 1 thereby make front rack 2.
Therefore, in the present embodiment, first carriage 2 and 2, and second carriage 6 and 6 is as supporting member, their fastening buffering crossbeams 3 are to the upper surface of leading flank element 1.
As shown in Figure 2, on the side of leading flank element 1, provide a support housing 5 here, the upper end of vehicle surge arrester (suspension) can cooperate therein.A first side wall 2a of front rack 2 is wall 5a that are spot welded to support housing 5, facing to leading flank element 1.As a result, front rack 2 has strengthened support housing 5, thereby improves the intensity of support housing 5.
Moreover, since front rack 2 and tail-bracket 6 be arranged on leading flank element 1 the first sweep 1d near, the load that is applied previously by vehicle is to transfer to buffering crossbeam 3 reposefully herein, and the impulsive force that is applied to leading flank element 1 transfers to buffering crossbeam 3 and effectively near the rear portion of centre portion 1b.Make the distortion that might avoid vehicle cabin effectively like this, and the impact absorption ability of improving vehicle.
Meanwhile, design preferably like this, make load be applied to the centre portion 1b of leading flank element 1 equably, and to cushioning crossbeam 3.
As shown in Figure 7, front rack 2 designs in such a way, makes its width W
2Equal the width W of leading flank element 1
1, width W wherein
1Be by increasing by two the first side wall 2a and thickness to the two the first side wall 2a of 2a and a value of the distance between the 2a, and width W wherein
2It is a value that obtains by the distance between thickness to two a sidewall 1h who increases by two sidewall 1h and 1h and the 1h.Tail-bracket 6 (not shown), in Fig. 7 it in the back of front rack 2, also be designed to have a width roughly with the width of front rack 2 (Here it is W
2) equate.
When observing from the front, as shown in Figure 7, the central axis A X of front rack 2 and tail-bracket 6
2Central axis A X with leading flank element 1
1Overlap, thereby make the position of the first side wall 2a and 2a, and the position of sidewall 6a and 6a is correctly to regulate on the Width of vehicle body.
In other words, the central axis A X of front rack 2 and tail-bracket 6
2Central axis A X with leading flank element 1
1Overlap, thereby the first side wall 2a of front rack 2 and the second sidewall 6a of 2a and tail-bracket 6 and the sidewall 1h and the 1h of 6a and leading flank element 1 are overlapped.Moreover, the first side wall 2a and 2a, and the second sidewall 6a and 6a are thinner than sidewall 1h and 1h.Therefore, the first side wall 2a and 2a on the two sides of front rack 2, and be to be placed on sidewall 1h on the two sides of leading flank element 1 and the thickness W of 1h at the second sidewall 6a on the two sides of tail- bracket 6 and 6a
1hAnd W
1hIn.
As a result, second sidewall 6a of the first side wall 2a of front rack 2 and 2a and tail- bracket 6 and 6a be placed on the sidewall 1h of leading flank element 1 and 1h almost directly over.Therefore, the load (impact/power) that is applied to front rack 2 by leading flank element 1 transfers to front rack 2 and tail-bracket 6 reliably.
The position and the thickness gauge that below are why front rack 2 and tail-bracket 6 are decided to be reason as previously discussed.Suppose in the sidewall 1h of leading flank element 1 and the width W between the 1h
1Greater than the first side wall 2a of front rack 2 and the width W between the 2a
2(Here it is, W
1＞W
2), if width W
1Thickness W with two sidewall 1h
1hBetween difference greater than width W
2(W
1-2W
1h＞W
2), the first side wall 2a and 2a be positioned at leading flank element 1 hollow parts 1j above.
If in this example, impact is to be applied to leading flank element 1, impact load can not transfer to front rack 2 by leading flank element 1 fully, because the first side wall 2a of impact absorption and 2a do not arrange just in time at sidewall 1h with above the 1h, thereby the hollow parts 1j that makes the first side wall 2a and 2a can break and enter leading flank element 1.
On the other hand, suppose in the sidewall 1h of leading flank element 1 and the width W between the 1h
1Less than the first side wall 2a of front rack 2 and the width W between the 2a
2(Here it is, W
1＜W
2), if width W
2Thickness W with two the first side wall 2a and 2a
2aDifference greater than width W
1(W
2-2W
2a＞W
1), the first side wall 2a and 2a are positioned on the flange 1g and 1g of leading flank element 1, perhaps even in the outside of flange 1g and 1g.In addition, the sidewall 1h of leading flank element 1 and 1h be placed on front rack 2 hollow parts 2d below.
Under the situation of previous examples, because impact absorption the first side wall 2a and 2a do not arrange just in time at sidewall 1h with above the 1h, the impact load that is applied to leading flank element 1 can not transfer to front rack 2 by leading flank element 1 fully, thereby makes the sidewall 1h of leading flank element 1 and the hollow parts 2d that 1h can break and enter front rack 2.
Opposite with these examples, in the present embodiment, the width W of front rack 2
2Width W with tail-bracket 6
2Width W with leading flank element 1
1Equate, and the central axis A X of front rack 2 and tail-bracket 6
2Central axis A X with leading flank element 1
1Overlap, input to leading flank element 1 and transmit this impact to cushioning crossbeam 3 thereby make front rack 2 and tail-bracket 6 receive load (impact) reliably.
Following effect and advantage have been realized according to the body structure of preferred embodiment of the present invention.
As shown in Figure 5, for example, if impact (load) F and be when inputing to leading flank element 1 on the direction forward from the collision of the previous section of vehicle, impact be distributed in the first sweep 1d of leading flank element 1 near, to the centre portion 1b that cushions crossbeam 3 and leading flank element 1.
Tail-bracket 6 and front rack 2, both support buffering crossbeam 3, be be fixed to leading flank element 1 the first sweep 1d near, it is positioned at the back of the leading portion 1a of leading flank element 1, thereby make the impact that is applied to leading flank element 1 transfer to buffering crossbeam 3 fully and near the rear portion of centre portion 1b, and can not influence the flattening property of leading portion 1a.Make like this and might avoid centering on distortion and the improvement impact absorption ability that vehicle cabin causes effectively.
Moreover buffering crossbeam 3 is with hollow steel elements manufacturing, and the centre portion 3a and the end portion 3b of buffering crossbeam 3 are configured as one.This arrangement make it reliably transmission payload input to the centre portion 3a of buffering crossbeam 3, not only to the end portion 3b that cushions crossbeam, but also to on-deck crossbeam 7 with to A-pillar 8, thereby avoid the generation of the crooked and fold of Z-shape.
And front rack 2 is the upper surfaces that are fixed to leading flank element 1, a position in its leading portion 1a back, and tail-bracket 6 to keep front racks 2 and buffering crossbeam 3 are the surfaces that are fixed to leading flank element 1, position of part 1b fwd therebetween.In addition, following three kinds of sidewalls are placed on the same position according to the Width of vehicle body: the first side wall 2a and the 2a of front rack 2; Second sidewall 6a and the 6a to bracket component 6; And the sidewall 1h and the 1h of leading flank element 1.This arrangement makes front rack 2 and tail-bracket 6 input to leading flank element 1 with receiving load (impact), and the impact that therefore absorbs transfers to buffering crossbeam 3 reliably.Therefore, not only absorbed to the impact of leading flank element 1 input, and also be dispensed to A-pillar 8 by leading flank element 1.
Here it is, the sidewall 2a of front rack 2, and the sidewall 6a of tail-bracket 6 and the sidewall 1h of leading flank element 1 are the same positions that is placed on according to vehicle-body width direction.This arrangement makes it might avoid the internal rupture of carriage 2,6 at leading flank element 1, and also avoids the internal rupture of leading flank element 1 at carriage 2,6, transfers to buffering crossbeam 3 reliably thereby make to the input of the load of carriage 2,6.
Moreover because the first side wall 2a and 2a, and the second sidewall 6a and 6a be thinner than 1h and 1h, transmitted reliably by sidewall 1h to the first side wall 2a with to the second sidewall 6a by the load of leading flank element 1 transmission.
And when being observed by its side, front rack 2 has a triangle roughly, and so simple structure makes it input to leading flank element 1 with receiving load (impact).In addition, so simple structure not only effectively transmission payload input to leading flank element 1, to cushioning crossbeam 3, but also can strengthen the fixing of buffering wallboard 4.
Moreover tail-bracket 6 is the positions that are right after the back that are fixed to buffering wallboard 4, and front rack 2 and tail-bracket 6 be fixed to one another, and buffering wallboard 4 is interposed between them, and therefore the fixing of buffering wallboard 4 be fastening.In addition, buffering wallboard 4 has been avoided moving backward, thereby a space to vehicle cabin is fixed.
Above explanation is at a preferred embodiment of the present invention and its change, and the present invention is in no way limited to above example, under the condition that does not break away from main points of the present invention, and various replacements and change and can advise using.
For example, use as the material of making buffering crossbeam 3 though a hollow steel pipe (tube element) has a circle cross-section, the steel element of other type also can use.
Moreover though buffering wallboard 4 is to be interposed between front rack 2 and the tail-bracket 6 in described embodiment, an independent carriage that has front rack 2 and tail-bracket 6 functions also can use, and buffering wallboard 4 is not often need be fixed to carriage.
Moreover though two ends of buffering crossbeam 3 are to be connected to on-deck crossbeam 7 in described embodiment, the end of buffering crossbeam 3 can instead be connected to A-pillar 8, thereby impact is directly distributed by buffering crossbeam 3 to A-pillar 8.For example, if on-deck crossbeam 7 is to be interposed between the right-hand member and left end of buffering crossbeam 3, near junction between buffering crossbeam 3 and the A-pillar 8, have one trapezoidal (rectangle), to described embodiment in a similar framed structure cushion crossbeam 3 thus and on-deck crossbeam 7 is formed, therefore body structure is enhanced.
And though front rack 2 has a right-angled triangle on its lateral plan, front rack 2 can have any other shape, as long as it can transmit impact load and input to leading flank element 1, to tail-bracket 6 and buffering crossbeam 3.In addition, a preferred shape is that it can satisfy described condition, and the structure enhancing of additionally bringing into play a corner fittings, and it is formed between the upper surface and buffering wallboard 4 of leading flank element 1.
Moreover though buffering crossbeam 3 is the upper surface that is fixed to the first sweep 1d of leading flank element 1 with tail-bracket 6 in described embodiment, buffering crossbeam 3 can directly be soldered to the junction between the buffering wallboard 4 and the first sweep 1d.Instead, the lower end of buffering wallboard 4 can have breach, thereby makes buffering crossbeam 3 directly be soldered to front rack 2.In both cases, buffering crossbeam 3 is to use front rack 2 to be connected to the upper surface of leading flank element 1.
