An end portion (hereinafter, simply referred to as “end portion”) 11 </ b> A of the front floor cross member 11 is coupled to a vertical wall portion of the side sill 10 by welding or the like.

車両１の側面部には、サイドシル１０によってその下端縁部が画成された開口部２０が形成されている。開口部２０には、フロントドア２１が、２個のヒンジ２２によって開閉自在に取り付けられる。   An opening 20 having a lower end edge defined by a side sill 10 is formed on a side surface of the vehicle 1. A front door 21 is attached to the opening 20 by two hinges 22 so as to be freely opened and closed.

フロントドア２１の本体は、アウタパネル２３とインナパネル２４との周縁部が接合されて形成されている。インナパネル２４の車室内側には、内張り部品であるドアトリム２５が取り付けられている。   The main body of the front door 21 is formed by joining the peripheral portions of the outer panel 23 and the inner panel 24. A door trim 25, which is a lining part, is attached to the inner side of the inner panel 24.

アウタパネル２３とインナパネル２４との間には、ボックス状の第１荷重伝達部材２６が溶接やボルトなどによって取り付けられている。第１荷重伝達部材２６の内部には、車両前後方向に所定の間隔で複数の縦壁（バルク）が車幅方向に沿って設けられており、荷重入力時に圧縮変形し難い構造になっている。なお、バルクに代えて、第１荷重伝達部材２６の内部に樹脂材を充填した構成としてもよい。   A box-shaped first load transmitting member 26 is attached between the outer panel 23 and the inner panel 24 by welding, bolts, or the like. Inside the first load transmission member 26, a plurality of vertical walls (bulk) are provided along the vehicle width direction at predetermined intervals in the vehicle front-rear direction, and the structure is difficult to compress and deform when a load is input. . Instead of the bulk, the first load transmission member 26 may be filled with a resin material.

フロントフロアクロスメンバ１１との結合部が形成されている部位のサイドシル１０上面部には、サブラッチ２７を構成する受け部２７Ａがボルトなどで取り付けられている。一方、フロントドア２１の下面部には、受け部２７Ａに対応した位置にサブラッチ２７を構成する突片２７Ｂがボルトなどで取り付けられている。サブラッチ２７は、フロントドア２１が閉じられたときに、車幅方向から見た断面形状がＬ字状をしている突片２７Ｂが受け部２７Ａと係合することによって、フロントドア２１とサイドシル１０とを係合するものである。すなわち、サブラッチ２７は係合部材として機能する。   A receiving portion 27A constituting the sub-latch 27 is attached to the upper surface portion of the side sill 10 at a portion where the coupling portion with the front floor cross member 11 is formed by a bolt or the like. On the other hand, a projecting piece 27B constituting the sub-latch 27 is attached to the lower surface of the front door 21 with a bolt or the like at a position corresponding to the receiving portion 27A. When the front door 21 is closed, the sub-latch 27 is engaged with the receiving portion 27A by the projecting piece 27B having a L-shaped cross section when viewed from the vehicle width direction. Is engaged. That is, the sub latch 27 functions as an engaging member.

サイドシル１０とフロントフロアクロスメンバ１１との結合部に対向するサイドシル１０内部には、第２荷重伝達部材１２が設けられている。第２荷重伝達部材１２としては、例えば、車両前後方向に所定の間隔をもって車幅方向に沿って設けられた複数のバルクが用いられる。また、仕切られたサイドシル１０の内部を樹脂材などで充填する構成としてもよい。   A second load transmission member 12 is provided inside the side sill 10 that faces the joint between the side sill 10 and the front floor cross member 11. As the second load transmission member 12, for example, a plurality of bulks provided along the vehicle width direction with a predetermined interval in the vehicle longitudinal direction are used. Further, the inside of the partitioned side sill 10 may be filled with a resin material or the like.

図２に示されるように、サブラッチ２７は、車幅方向から見て、第１荷重伝達部材２６、第２荷重伝達部材１２及びフロントフロアクロスメンバ１１の端部１１Ａそれぞれに車両前後方向にオーバーラップする位置に配設されている。なお、必ずしもサブラッチ２７の全体がオーバーラップする必要はなく、サブラッチ２７の少なくとも一部が、車幅方向から見て、第１荷重伝達部材２６、第２荷重伝達部材１２及びフロントフロアクロスメンバ１１の端部１１Ａそれぞれに車両前後方向にオーバーラップするように配設されていればよい。   As shown in FIG. 2, the sub-latch 27 overlaps the first load transmission member 26, the second load transmission member 12, and the end portion 11 </ b> A of the front floor cross member 11 in the vehicle longitudinal direction when viewed from the vehicle width direction. It is arranged at the position to do. Note that the entire sub-latch 27 is not necessarily overlapped, and at least a part of the sub-latch 27 is seen from the vehicle width direction, and the first load transmission member 26, the second load transmission member 12, and the front floor cross member 11 What is necessary is just to be arrange | positioned so that it may overlap in the vehicle front-back direction at each edge part 11A.

以上の構成において、図１に白抜き矢印で示されるように、他車のバンパ等によって車両の外部側方からフロントドア２１に荷重が入力された場合、入力荷重は第１荷重伝達部材２６、サブラッチ２７及び第２荷重伝達部材１２を介してフロントフロアクロスメンバ１１に伝達されて吸収される。   In the above configuration, as shown by the white arrow in FIG. 1, when a load is input to the front door 21 from the outside of the vehicle by a bumper or the like of another vehicle, the input load is the first load transmission member 26, It is transmitted to the front floor cross member 11 through the sub-latch 27 and the second load transmitting member 12 and absorbed.

以上の構成において、図４に白抜き矢印で示されるように、他車のバンパ等によって車両の外部側方からリアドア３１に荷重が入力された場合、入力荷重は第３荷重伝達部材３６、第４荷重伝達部材３７及び荷重受け部材１４を介してセンタフロアクロスメンバ１３に伝達されて吸収される。   In the above configuration, as indicated by the white arrow in FIG. 4, when a load is input to the rear door 31 from the outside of the vehicle by a bumper or the like of another vehicle, the input load is the third load transmission member 36, It is transmitted to the center floor cross member 13 via the four load transmitting member 37 and the load receiving member 14 and absorbed.

このとき、第４荷重伝達部材３７が、車幅方向から見て、第３荷重伝達部材３６、荷重受け部材１４それぞれに重なる位置に配設されているので、入力荷重を短い距離でセンタフロアクロスメンバ１３に伝達することができる。また、第３荷重伝達部材３６、第４荷重伝達部材３７及び荷重受け部材１４は、圧縮変形され難く荷重の吸収が少ないので、荷重の伝達効率を向上することができる。   At this time, since the fourth load transmission member 37 is disposed at a position overlapping each of the third load transmission member 36 and the load receiving member 14 when viewed from the vehicle width direction, the input load can be reduced at a short distance from the center floor cross. It can be transmitted to the member 13. Further, since the third load transmission member 36, the fourth load transmission member 37, and the load receiving member 14 are hardly compressed and deformed and absorb little load, the load transmission efficiency can be improved.

そのため、本実施形態によれば、図６に実線で示されるように、従来構造（図６の破線参照）と比較して、センタフロアクロスメンバ１３への入力荷重の立ち上がり特性を急にすることができる。その結果、従来構造と比較して、同一のボディ変形量における入力荷重を増大することが可能となる。また、本実施形態によれば、車室内に荷重伝達部材を設ける必要がないので、車室内の居住性が悪化しない。   Therefore, according to the present embodiment, as shown by a solid line in FIG. 6, the rising characteristic of the input load to the center floor cross member 13 is made steep as compared with the conventional structure (see the broken line in FIG. 6). Can do. As a result, the input load at the same body deformation amount can be increased as compared with the conventional structure. Moreover, according to this embodiment, since it is not necessary to provide a load transmission member in a vehicle interior, the comfortability in a vehicle interior is not deteriorated.

以上、本発明の実施の形態について詳細に説明したが、本発明は、上記実施形態に限定されるものではなく種々の変形が可能である。例えば、第１荷重伝達部材２６、第２荷重伝達部材１２、第３荷重伝達部材３６、第４荷重伝達部材３７及び荷重受け部材１４それぞれの形状、構造、材質などは上記実施形態に限られるものではなく、適用される車両や想定される入力荷重の大きさ等に応じて異なる形状や構造などを採用してもよい。   As mentioned above, although embodiment of this invention was described in detail, this invention is not limited to the said embodiment, A various deformation | transformation is possible. For example, the shape, structure, material, etc. of each of the first load transmission member 26, the second load transmission member 12, the third load transmission member 36, the fourth load transmission member 37, and the load receiving member 14 are limited to those in the above embodiment. Instead, different shapes and structures may be employed depending on the vehicle to be applied and the assumed input load.
