Described the 1st～the 5th embodiment is the structure with a door beam, but the following automobile door that illustrates about embodiment with two door beams.
Fig. 8 (a) and (b) are the section-drawing of the car door 10 of the 6th embodiment of the present invention shown in arrow A-A, the B-B among Fig. 1.
In the 6th embodiment, dispose a plurality of beams i.e. door beam 16a and 16b (at this, two of upper-lower position configurations, below be 16a with the upper side of automobile, lower side is 16b) in the inboard of car door 10.
And, between up and down the door beam 16a and 16b, be provided with brace panel 20 with concavo-convex steel plate system for the collision energy that absorbs side collision.Brace panel 20 have coincide with the shape of lateral surface with the face of joint 20a of outer side engagement and the face of joint 20b that engages with door beam 16a and 16b, and engage by lining cement 18 and outer panel 13 and a beam 16a and 16b respectively.In addition, side before and after vehicle engages edge portion and interior plate 14 that brace panel 20 is arranged at least.
Shown in Fig. 8 (b), door beam 16a sets along the vehicle fore-and-aft direction, and its end engages with interior plate 14 via brace panel 20. Door beam 16a and 16b are linearity roughly, so beam 16a and 16b and have between the outer panel 13 of the shape that has fillet on the fore-and-aft direction of vehicle and produce the gap.At this, the gap size between outer panel 13 and the door beam 16a sets direction and difference according to door beam 16a's, so the concavo-convex of the brace panel 20 that is set has and the identical difference of height of gap size.In addition, in Fig. 8 (b), only showing and go up side door beam 16a, is same about following side door beam 16b.
Present embodiment to the side collision of car door 10 time, from the collision energy of other vehicles (collision vehicle) from the internal delivery of outer panel 13 to car door 10.At this moment, brace panel 20 in the opposing impact load and be out of shape, thereby absorb collision energy.In addition, two door beam 16a that engage with brace panel 20 and 16b be with planar reception impact load, opposing bending load and suppress entering of car door, and impact load passes to interior plate 14 and car body from door beam 16a via brace panel 20.Thus, car door and car body form one and resist car door the entering to vehicle interior that impact load causes.
Fig. 9 and Fig. 3 are the inlet of the collision vehicle when representing side collision and the skeleton diagram that the relation of load takes place similarly.In addition, in the above-mentioned automobile door structure in the past, a door beam equal with the door beam of present embodiment shown in Figure 8 sets two towards vehicle heading, is filled with lining cement in the gap between outer panel and door beam.
The scope of Fig. 9 (a) represents that the sky that the gap between outer panel 13 and door beam 16a and the 16b causes sails the space.In the automobile door structure in the past, in the scope of (a), the increase that load takes place is smaller with respect to the increase of vehicle inlet.Afterwards, the vehicle inlet surpasses sky sails the space and becomes big, and the then Men Liang load that is collided is so as Fig. 9 (b) shown in, the increase that load takes place becomes greatly with respect to the increase of vehicle inlet.When the vehicle inlet further increases, then shown in Fig. 9 (c), load takes place have no change with respect to the increase of vehicle inlet.
With respect to this, in the automobile door structure of present embodiment, in the scope of Fig. 9 (a), after just entering, also show the ratio big generation load of automobile door structure in the past from vehicle.This means, be out of shape by making the brace panel that is provided between outer panel and the door beam, thereby can efficient absorb collision energy well.
Afterwards, the vehicle inlet increases and becomes sky and sail the space, and then impact load is directly passed to a beam 16a and 16b (Fig. 9 (b)).In automobile door structure in the past, because the door beam is provided with separately in girder construction, so easy torsional deflection can not efficient absorb energy well.According to present embodiment, by linking two door beams, so each beam produces the effect of the torsional deflection that suppresses another beam with brace panel.Therefore, form one and with the planar impact load of bearing by the structure that makes a beam and brace panel, thereby can efficient absorb collision energy well.Its result compares with structure in the past, can make load takes place to increase with respect to the vehicle inlet.
