Detailed description of the invention
According to Fig. 1, Fig. 2, the Vehicular side body structure 1 of present embodiment is described.
The Vehicular side body structure 1 of present embodiment as shown in Figure 1 and Figure 2, is the structure that lower longeron 3 engages with center pillar 5.
The lower longeron 3 of present embodiment possesses: closed section parts 9, a blank plate is configured as tubular and is engaged at both ends thus form closed section, and the flange part 7 be made up of above-mentioned both ends is configured in inside car; Strengthening part 13, in the inside of these closed section parts 9, installs this strengthening part 13 in the mode of the relative longitudinal wall connecting closed section parts 9.
And outside the car of closed section parts 9, center pillar exterior part 5a is to cover the mode welded joint on the surface of closed section parts 9.In addition, inside the car of closed section parts 9, center pillar inner component 5b is to cover the mode welded joint on the surface of closed section parts 9.
In addition, as shown in Figure 2, the flange part 7 inside the car being formed at above-mentioned closed section parts 9 engages with base plate 15.In addition, the diagram of base plate 15 is eliminated in FIG.
The strengthening part 13 of present embodiment, as shown in Figure 2, is at least configured in region that closed section parts 9 engage with center pillar exterior part 5a and center pillar inner component 5b.
By arranging strengthening part 13 like this, when applying external force to lower longeron 3, strengthening part 13 can prevent the section deformation of closed section parts 9, can obtain high rigidity and intensity.
In addition, the region of the axis of the lower longeron 3 of strengthening part 13 is set, as described above, is at least the region that closed section parts 9 engage with center pillar exterior part 5a and center pillar inner component 5b, arranges with also can exceeding this region.
In addition, in the present embodiment, form the lower closed section parts 9 of longeron 3 and the engage position of strengthening part 13 and closed section parts 9 overlapping with the engage position of center pillar exterior part 5a and center pillar inner component 5b.If such engage position relation, then when the side collision that other cars are come from car outside collision, be dispersed to closed section parts 9 and the strengthening part 13 of longeron 3 formation from the power of center pillar 5 transmission, therefore, it is possible to obtain better intensity.
In the Vehicular side body structure 1 of the present embodiment formed as described above, due to the flange part of the total length and the position, top and bottom existed that there are not the top and bottom throughout lower longeron as conventional example, therefore the effect of lightness is high.
In addition, strengthening part 13 is set by the inside of the closed section parts of longeron 3 under forming, the section deformation of closed section parts 9 can be prevented, thus there is high rigidity and intensity.
That is, in the Vehicular side body structure 1 of present embodiment, omit in conventional example exist to rigidity, intensity without the flange part helped, and by contributing to rigidity, the parts of intensity form lower longeron, therefore can realize lightness while the rigidity required by maintaining, intensity.
Further, in the present embodiment, the flange part 7 being formed at closed section parts 9 is different from the flange part of the conventional example without any function, but plays a role as the junction surface with base plate 15.
In addition, the position of the short transverse of flange part 7, non-essential is the lower end of closed section parts 9, also can be the position higher than lower end.
Embodiment
Carry out the performance test of the Vehicular side body structure 1 of above-mentioned present embodiment, be therefore described.
Fig. 3, Fig. 4 are the instruction diagrams of the test body (example test body 21) of the Vehicular side body structure 1 of present embodiment, Fig. 3 is the block diagram observed inside car example test body 21, and Fig. 4 is the block diagram observing the state that the longitudinal wall inside by the car of the center pillar inner component 5b of example test body 21 and lower longeron 3 is pulled down inside car.In Fig. 3, Fig. 4, represent the Reference numeral of each several part of example test body 21 and to be labeled in Fig. 1, Fig. 2 identical.
In addition, as shown in Figure 4, example test body 21 strengthening part 13 lower longeron 3 axially before and after the region that engages with center pillar exterior part 5a and center pillar inner component 5b just over closed section parts 9 be configured.
Fig. 5, Fig. 6 are the instruction diagrams of the test body (conventional example test body 31) of conventional example, and Fig. 5 is the block diagram observed inside car, and Fig. 6 is the block diagram observing the state pulled down by lower rail inner part 33b inside car.According to Fig. 5, Fig. 6, as conventional example test body 31, lower longeron 33 is made up of with the lower rail outer part 33a being similarly open cross-sections parts the lower rail inner part 33b of open cross-sections parts, is docked by the upper and lower flange part 35 of these two open cross-sections parts and engages the lower longeron 33 forming closed section thus.In addition, center pillar 36 is made up of with the post exterior part 36a being similarly open cross-sections parts the post inner component 36b of open cross-sections parts, post exterior part 36a engages with lower rail outer part 33a, and post inner component 36b engages with post exterior part 36a and engages in the mode of being clamped by lower rail inner part 33b and lower rail outer part 33a.
The size of each test body is as shown in Fig. 3, Fig. 5.In addition, the material used is for conventional example and the present invention's example, and all parts are all the steel plates of thickness of slab 1.2mm.
Fig. 7 is the instruction diagram using the implosion test method of example test body 21 pairs of the present embodiment to be described.According to Fig. 7, implosion test method is described.
The face, rear and front end of the lower longeron 3 of example test body 21 is fixed, in the upper end of center pillar 5, respectively apply front to load (Fx), the load (Fy) in interior direction, upper direction load (Fz).As load level, front to time be 10kN, being 1kN during interior direction, is 10kN during upper direction.
The comparative result of conventional example test body 31 based on implosion test and example test body 21 is represented in Fig. 8.
In addition, for the rigidity of each test body, in order to obtain the rigidity of unit weight, with the rigidity of the unit weight of conventional example test body 31 for benchmark, the rigidity ratio of example test body 21 is represented.
When be applied with as shown in Figure 8 (a) front to load time, example test body 21 and conventional example test body 31 are in a ratio of about 1.2 times.In addition, as shown in Figure 8 (b) shows, when the load in direction in applying, example test body 21 and conventional example test body 31 are in a ratio of about 7 times.In addition, as shown in Fig. 8 (c), when being applied with the load in direction, example test body 21 and conventional example test body 31 are in a ratio of about 4 times.
Like this, confirm that example test body 21 all possesses the rigidity exceeding conventional example test body 31 for arbitrary load direction.
Next, carried out the strength test of imaginary side collision, be therefore described.
In strength test, as shown in Figure 9, outside car, inside car, release the drift 37 of front-end radius 100mm with speed 10m second, the junction surface of lower longeron 3 and center pillar 5 is clashed into.Load during shock is measured by the force transducer 39 of the position of the upper end at the both ends and center pillar 5 that are arranged on lower longeron 3.And, the performance of ranking test body is carried out by the summation of the output valve of 3 force transducers 39.
The comparative result of conventional example test body 31 based on strength test and example test body 21 is represented in Figure 10.
As shown in Figure 10, compared with conventional example test body 31, example test body 21 shows the resistant load of about 1.3 times.
According to above test results, confirm that the present invention is the Vehicular side body structure that can realize lightness compared with conventional example maintaining rigidity, intensity while.
