Description
本発明は、アウタパネルとこのアウタパネルと協働して上下方向に延びる閉断面を構成するインナパネルとを有するヒンジピラーと、このヒンジピラーの下端部から車体後方に延びるサイドシルとを備えた車両の側部車体構造に関する。 The present invention relates to a side body of a vehicle including a hinge pillar having an outer panel and an inner panel having a closed section extending in the vertical direction in cooperation with the outer panel, and a side sill extending from the lower end of the hinge pillar to the rear of the vehicle body. Concerning structure.
従来より、車両の車体側部には、前後方向に延びるルーフサイドレールの前端部（フロントヘッダの側端部）と前後方向に延びるサイドシルの前端部とを上下方向に連結するヒンジピラー及びこのヒンジピラーの上端に連なるフロントピラーが設けられている。
ヒンジピラーは乗員乗降口の周縁部の前側部分を構成しているため、フロントドアを乗員乗降口に対して開閉自在に枢支するための上下１対のドアヒンジがヒンジピラーに取り付けられている。
Conventionally, on a vehicle body side portion of a vehicle, a hinge pillar that vertically connects a front end portion (a side end portion of a front header) of a roof side rail extending in the front-rear direction and a front end portion of a side sill extending in the front-rear direction, and the hinge pillar A front pillar connected to the upper end is provided.
Since the hinge pillar constitutes the front portion of the peripheral part of the passenger entrance / exit, a pair of upper and lower door hinges for pivotally supporting the front door so as to be openable / closable with respect to the passenger entrance / exit is attached to the hinge pillar.
ヒンジピラーは、前輪に対して前後方向後側に対向するように配設されている。
前面衝突が発生した際、衝突荷重によって前輪が後退するため、後退した前輪を介して衝撃緩和されていない衝突荷重が車体側に作用することがある。
スモールオーバーラップ衝突（以下、ＳＯＬ衝突と略す）では、自車両に衝突する衝突物とフロントサイドフレームとがオーバーラップしていないため、後退した前輪がヒンジピラーに干渉する。それ故、前輪から入力した後方に向かう衝突荷重によりヒンジピラー周りの車室空間が変形する虞があった。
The hinge pillar is disposed so as to face the rear side in the front-rear direction with respect to the front wheel.
When a frontal collision occurs, the front wheel moves backward due to the collision load. Therefore, a collision load that is not relieved in impact may act on the vehicle body side through the moved front wheel.
In a small overlap collision (hereinafter abbreviated as SOL collision), the colliding object that collides with the host vehicle and the front side frame do not overlap with each other, and the front wheel that has moved back interferes with the hinge pillar. Therefore, there is a possibility that the passenger compartment space around the hinge pillar is deformed by a rearward collision load input from the front wheel.
近年、燃費改善及び車体重量の軽量化を狙いとして、車体の骨格部材をアルミ合金材料を用いて形成することが行われている。
特許文献１のフロントピラー構造は、フロアサイドメン（サイドシル）の前端部とサイドレールの前端部とを連結するフロントピラー（ヒンジピラー）をアルミ合金ダイキャストにて構成し、車体前方から作用する荷重が、フロントピラーの上方後端部を介してサイドレールとフロントドアのベルトラインに設けた補強材とに伝達可能に構成され、フロントピラーの上方後端部を高剛性構造とし、フロントピラーの上方後端部と上方前端部間に補強材及び上方後端部よりも強度が弱く且つエネルギー吸収可能な変形可能部を設けている。
In recent years, for the purpose of improving fuel consumption and reducing the weight of a vehicle body, a skeleton member of the vehicle body is formed using an aluminum alloy material.
In the front pillar structure of Patent Document 1, the front pillar (hinge pillar) that connects the front end portion of the floor side men (side sill) and the front end portion of the side rail is configured by aluminum alloy die casting, and the load acting from the front of the vehicle body is It is configured to be able to transmit to the side rail and the reinforcing material provided on the belt line of the front door via the upper rear end of the front pillar, the upper rear end of the front pillar has a high rigidity structure, and the upper rear end of the front pillar A deformable portion having a lower strength than the reinforcing material and the upper rear end and capable of absorbing energy is provided between the upper portion and the upper front end.
特許文献１のフロントピラー構造は、車両の前突時における衝突荷重を変形可能部の座屈変形及び折れ曲がり変形によって吸収し、車室空間の変形を抑制している。
しかし、特許文献１のフロントピラー構造では、フロントサイドフレームを介して作用する衝突荷重を効率的に吸収することができるものの、ＳＯＬ衝突については一切考慮されていない。それ故、衝突物とフロントサイドフレームとがオーバーラップしていないＳＯＬ衝突が発生したとき、乗員乗降口の前側下方周縁部を形成するヒンジピラーの下端側部分が座屈変形し、車室空間が変形する虞がある。
特に、ヒンジピラーを強度（耐力）が低いアルミ合金材料等を用いて形成する場合、車室空間の変形量の増加が懸念される。
The front pillar structure of Patent Document 1 absorbs a collision load at the time of a frontal collision of a vehicle by buckling deformation and bending deformation of the deformable portion, and suppresses deformation of the vehicle interior space.
However, although the front pillar structure of Patent Document 1 can efficiently absorb the collision load acting via the front side frame, no consideration is given to the SOL collision. Therefore, when a SOL collision occurs where the collision object and the front side frame do not overlap, the lower end portion of the hinge pillar that forms the front lower peripheral edge of the passenger entrance / exit is buckled and deformed. There is a risk of doing.
In particular, when the hinge pillar is formed using an aluminum alloy material or the like having low strength (yield strength), there is a concern about an increase in the deformation amount of the passenger compartment space.
本発明の目的は、スモールオーバーラップ衝突による車室空間の変形を防止可能な車両の側部車体構造等を提供することである。 An object of the present invention is to provide a vehicle side body structure or the like that can prevent deformation of a passenger compartment space due to a small overlap collision.

Thereby, at the time of a small overlap collision, buckling deformation of the lower end side portion of the hinge pillar that forms the front lower peripheral edge portion of the passenger entrance and exit can be suppressed, and deformation of the vehicle interior space can be prevented.

次に、上記車両Ｖの側部車体構造の作用・効果について説明する。
この車両Ｖの側部車体構造によれば、サイドシル３の前端部の上側近傍部位にサイドシル３の前端部よりも耐力が小さい衝撃吸収部材２０を設けたため、閉断面Ｃ内に収容された衝撃吸収部材２０（閉断面部２２）によってヒンジピラー２０の下端側部分に作用する後方に向かう衝突荷重を吸収し、衝撃吸収部材２０によって吸収することができない残りの衝突荷重をサイドシル３を用いて車体後方に分散伝達している。これにより、スモールオーバーラップ衝突時、フロントドア用開口部４の前側下方周縁部を形成するヒンジピラー１０の下端側部分の座屈変形を抑制し、車室空間の変形を防止することができる。
Next, functions and effects of the side body structure of the vehicle V will be described.
According to the side body structure of the vehicle V, the shock absorbing member 20 having a lower proof strength than the front end portion of the side sill 3 is provided in the vicinity of the upper side of the front end portion of the side sill 3, so that the shock absorption accommodated in the closed cross section C is provided. The rearward collision load acting on the lower end portion of the hinge pillar 20 is absorbed by the member 20 (closed section 22), and the remaining collision load that cannot be absorbed by the shock absorbing member 20 is rearward using the side sill 3. Distributed transmission. Thereby, the buckling deformation | transformation of the lower end side part of the hinge pillar 10 which forms the front side lower periphery part of the opening part 4 for front doors at the time of a small overlap collision can be suppressed, and a deformation | transformation of a vehicle interior space can be prevented.
衝撃吸収部材２０がサイドシル３の上壁部に当接する後壁部２２ｄを有し、後壁部２２ｄが下側程車体後方に移行するように形成されたため、衝突荷重を吸収しつつ、衝撃吸収部材２０（閉断面部２２）によって吸収することができない残りの衝突荷重を閉塞部２１を介して能率的にサイドシル３へ伝達することができる。 The shock absorbing member 20 has a rear wall portion 22d that contacts the upper wall portion of the side sill 3, and the rear wall portion 22d is formed so as to move toward the rear of the vehicle body toward the lower side. The remaining collision load that cannot be absorbed by the member 20 (closed section 22) can be efficiently transmitted to the side sill 3 via the closing portion 21.
ヒンジピラー１０の前端部から前方に延びるエプロンレインフォースメント（１１ｂ，１２ｂ）と、ヒンジピラー１０とエプロンレインフォースメントとを連結する前方上り傾斜状の連結部材（１１ｅ，１２ｂ）とを有し、連結部材の延長線が衝撃吸収部材２０の後壁部２２ｄの面上に位置するように構成されたため、エプロンレインフォースメントから入力される衝突荷重を衝撃吸収部材２０によって吸収しつつサイドシル３に伝達することができる。 An apron reinforcement (11b, 12b) that extends forward from the front end of the hinge pillar 10 and a forward upward inclined connecting member (11e, 12b) that connects the hinge pillar 10 and the apron reinforcement, are connected members. Since the extension line is positioned on the surface of the rear wall portion 22d of the shock absorbing member 20, the collision load input from the apron reinforcement is transmitted to the side sill 3 while being absorbed by the shock absorbing member 20. be able to.
アウタパネル１１の下端側部分に、衝撃吸収部材２０とサイドシル３の前端側部分を覆う補強部材１３を設けたため、衝突荷重を衝撃吸収部材２０に対して略均一に分散伝達することができ、衝撃荷重吸収機能と荷重伝達機能との協働作用を高くすることができる。 Since the reinforcing member 13 that covers the impact absorbing member 20 and the front end side portion of the side sill 3 is provided at the lower end portion of the outer panel 11, the collision load can be distributed and transmitted to the impact absorbing member 20 substantially uniformly. The cooperative action between the absorption function and the load transmission function can be increased.
次に、前記実施形態を部分的に変更した変形例について説明する。
１〕前記実施形態においては、サイドシルと衝撃吸収部材とを何れもアルミ合金で構成した例を説明したが、少なくとも、サイドシルの前端部よりも耐力、換言すれば圧縮方向の強度が小さい衝撃吸収部材であれば良く、アルミ合金以外の軽合金又は鋼材料等仕様に応じて選択的に採用することができる。また、同様の材料を使用する必要はなく、サイドシルをハイテン鋼、衝撃吸収部材を軽合金としても良い。

また、閉塞部と閉断面部とを共に立体状に形成しても良い。この場合、閉塞部と閉断面部との耐力調節により、サイドシルの材質等に拘らず衝撃荷重吸収機能と荷重伝達機能とを確保することができる。
2) In the above embodiment, the shock absorbing member is composed of a plate-like closed portion and a three-dimensional closed cross-sectional portion, and an example in which these are integrally press-molded has been described. The shock absorbing member may be formed by forming a separate body and mechanically joining the two later.
Moreover, you may form both a closure part and a closed cross-section part in three-dimensional form. In this case, the impact load absorbing function and the load transmitting function can be ensured regardless of the material of the side sill, etc., by adjusting the proof stress between the closed portion and the closed cross section.
