Description

本発明は車体前部構造に関し、特に、自動車等の車体において衝突体に衝突した際に、衝突体を保護する車体前部構造に関する。   The present invention relates to a vehicle body front structure, and more particularly to a vehicle body front structure that protects a collision body when the vehicle collides with a collision body in a vehicle body such as an automobile.

従来から、自動車等の車体において衝突体に衝突した際に、衝突体を保護する車体前部構造においては、車体のエンジンルームの前端上部のラジエータサポートアッパに、フードを閉状態にロックするフードロックを固定し、フードロックとエンジンルームの前端下部のフロントクロスメンバとの間に、上下方向にセンタブレース（フードロックサポートブレースともいう）を架設してフードロックを支持すると共に、センタブレースの下部に、フロントクロスメンバ側へ屈曲する屈曲部を設け、この屈曲部から延出する下端部の下端末をフロントクロスメンバと結合した構成が知られている（例えば、特許文献１参照）。
特開２００３−３０６１６８号公報 Conventionally, in a vehicle body front structure that protects a collision body when it collides with a collision body in a vehicle body such as an automobile, a hood lock that locks the hood in a closed state on the radiator support upper of the front end of the engine room of the vehicle body A centab race (also called a hood lock support brace) is installed vertically between the hood lock and the front cross member at the lower front end of the engine room to support the hood lock and at the bottom of the centab race. A configuration is known in which a bent portion that bends toward the front cross member is provided, and a lower terminal at the lower end that extends from the bent portion is coupled to the front cross member (see, for example, Patent Document 1).
Japanese Patent Laid-Open No. 2003-306168

しかしながら、特許文献１では、フードの前部に衝突体が衝突してフードの前部を介してセンタブレースに車体上方斜め前方から荷重が作用すると、センタブレースは屈曲部が折れ曲がると共に下端部が変形してフードロック及びラジエータサポートアッパが落ち込み変位することで、フードの前部が大きく撓み変形して衝突体への衝撃を緩和するようになっている。この結果、衝突時でない通常状態での車体上方からのフードへの入力荷重に対してもフードロック及びラジエータサポートアッパが落ち込み変位し易くなる。このため、衝突体の衝撃緩和とフード入力荷重に対する剛性確保の両立ができない。   However, in Patent Document 1, when a collision body collides with the front part of the hood and a load acts on the senta race from the front side of the vehicle body through the front part of the hood, the bent part of the centab race is bent and the lower end part is deformed. When the hood lock and the radiator support upper are lowered and displaced, the front portion of the hood is greatly bent and deformed to reduce the impact on the collision object. As a result, the hood lock and the radiator support upper are likely to fall down and displace even with respect to the input load to the hood from above the vehicle body in a normal state not during a collision. For this reason, it is impossible to achieve both relaxation of the impact of the collision body and securing of rigidity against the hood input load.

本発明は上記事実を考慮し、衝突体の衝撃緩和とフード入力荷重に対する剛性確保の両立ができる車体前部構造を提供することが目的である。   In view of the above facts, an object of the present invention is to provide a vehicle body front part structure capable of both reducing the impact of an impactor and ensuring rigidity against a hood input load.

請求項１記載の本発明の車体前部構造は、車体前部上方に車幅方向に沿って配設されたラジエータサポートアッパメンバと、
前記ラジエータサポートアッパメンバに対向してエンジンルームの前端下部に車幅方向に沿って配設されたフロントクロスメンバと、
前記ラジエータサポートアッパメンバの車幅方向両端部と前記フロントクロスメンバの車幅方向両端部とを連結する左右のラジエータサポートサイドと、
前記ラジエータサポートアッパメンバの後壁部に固定されたフードロックと、
前記ラジエータサポートアッパメンバに形成され、前記ラジエータサポートアッパメンバの側断面形状を車体前方斜め上方側が開く開断面とする開口部と、
を有し、前記ラジエータサポートアッパメンバの後壁部が車体垂直方向に立設されていると共に、前記左右のラジエータサポートサイドで前記ラジエータサポートアッパメンバの車幅方向両端部と前記フロントクロスメンバの車幅方向両端部とを連結することで、前記ラジエータサポートアッパメンバの車幅方向中央部と前記フロントクロスメンバの車幅方向中央部とを連結しないことを特徴とする。 The vehicle body front structure according to the first aspect of the present invention includes a radiator support upper member disposed along the vehicle width direction above the vehicle body front,
A front cross member disposed along the vehicle width direction at the lower front end of the engine room facing the radiator support upper member;
Left and right radiator support sides connecting both ends of the radiator support upper member in the vehicle width direction and both ends of the front cross member in the vehicle width direction;
A hood lock fixed to a rear wall portion of the radiator support upper member;
An opening formed in the radiator support upper member, and having an open cross-section in which the side cross-sectional shape of the radiator support upper member opens obliquely upward on the front side of the vehicle body;
A rear wall portion of the radiator support upper member is erected in the vertical direction of the vehicle body, and both ends of the radiator support upper member in the vehicle width direction on the left and right radiator support sides and the vehicle of the front cross member By connecting both ends in the width direction, the center portion in the vehicle width direction of the radiator support upper member and the center portion in the vehicle width direction of the front cross member are not connected .

従って、車体前部上方に車幅方向に沿って配設され、後壁部にフードロックが固定されたラジエータサポートアッパメンバにおいて、ラジエータサポートアッパメンバの側断面形状を車体前方斜め上方側が開く開断面とする開口部を形成したため、フードの前部に衝突体が車体前方上側から車体後方下側に向かって衝突した場合には、ラジエータサポートアッパメンバが衝突体当接部を起点に容易に折れ曲がると共に車体前方上側から車体後方下側に向かって変形する。この結果、フードの前部が大きく撓み変形して衝突体への衝撃を緩和することができる。また、左右のラジエータサポートサイドでラジエータサポートアッパメンバの車幅方向両端部とフロントクロスメンバの車幅方向両端部とを連結することで、ラジエータサポートアッパメンバの車幅方向中央部とフロントクロスメンバの車幅方向中央部とを連結しないため、この点においても、ラジエータサポートアッパメンバが衝突体当接部を起点に容易に折れ曲がり、衝突体への衝撃を緩和することができる。一方、衝突時でない通常状態での車体上方からのフードへの入力荷重に対しては、フードロックが固定されたラジエータサポートアッパメンバの後壁部が車体垂直方向に立設されていると共に、ラジエータサポートアッパメンバの側断面形状を車体前方斜め上方側が開く開断面とする開口部を形成したことで、ラジエータサポートアッパメンバにおける上方からの荷重を最も確実に支持できる位置である剪断中心が後壁部の後方となり、この剪断中心上にフードロックを配設することができる。この結果、衝突時でない通常状態での車体上方からのフードへの入力荷重に対しては、ラジエータサポートアッパメンバは容易に変形しない。このため、衝突体の衝撃緩和とフード入力荷重に対する剛性確保の両立ができる。 Therefore, in the radiator support upper member which is disposed along the vehicle width direction above the front portion of the vehicle body and the hood lock is fixed to the rear wall portion, the side cross-sectional shape of the radiator support upper member is opened at the diagonally upper front side of the vehicle body. When the collision object collides with the front part of the hood from the upper front side of the vehicle body toward the lower rear side of the vehicle body, the radiator support upper member is easily bent from the collision object contact part as a starting point. Deformation from the upper front side of the vehicle body toward the lower rear side of the vehicle body. As a result, the front portion of the hood can be greatly deformed and the impact on the collision object can be reduced. Further, by connecting the both ends of the radiator support upper member in the vehicle width direction and the both ends of the front cross member in the vehicle width direction on the left and right radiator support sides, the center portion of the radiator support upper member in the vehicle width direction and the front cross member Since the central portion in the vehicle width direction is not connected, the radiator support upper member can be easily bent from the collision body contact portion at this point, and the impact on the collision body can be reduced. On the other hand, with respect to the input load to the hood from above the vehicle body in a normal state not during a collision, the rear wall of the radiator support upper member to which the hood lock is fixed is erected in the vertical direction of the vehicle body, and the radiator By forming an opening with a side cross-sectional shape of the support upper member that opens obliquely upward on the front side of the vehicle body, the rear wall is the shear center that is the position that can most reliably support the load from above on the radiator support upper member. A hood lock can be disposed on the shear center. As a result, the radiator support upper member is not easily deformed with respect to an input load to the hood from above the vehicle body in a normal state that is not during a collision. For this reason, it is possible to achieve both relaxation of the impact of the collision body and securing of rigidity against the hood input load.

また、本実施形態では、従来配設されていたラジエータサポートアッパメンバ１２の車幅方向中央部とフロントクロスメンバ４０の車幅方向中央部とを連結するセンタブレースは配設されていない。   In the present embodiment, the center race that connects the center portion in the vehicle width direction of the radiator support upper member 12 and the center portion in the vehicle width direction of the front cross member 40 that are conventionally provided is not provided.

次に、本実施形態の作用を説明する。   Next, the operation of this embodiment will be described.

本実施形態では、車体前部上方に車幅方向に沿って配設され、後壁部１２Ｃにフードロックブラケット３４を介してフードロック３６が固定されたラジエータサポートアッパメンバ１２において、ラジエータサポートアッパメンバ１２の側断面形状を車体前方斜め上方側が開く開断面とする開口部２０、２２を形成したため、図２に示される如く、フード５２の前部５２Ａに衝突体Ｋが車体前方上側から車体後方下側方向（図２の矢印Ａ方向）に向かって衝突した場合には、ラジエータサポートアッパメンバ１２が衝突体当接部を起点に容易に折れ曲がると共に図２に二点鎖線で示すように車体前方上側から車体後方下側方向（図２の矢印Ｂ方向）に向かって変形する。この結果、フード５２の前部５２Ａが、図２に二点鎖線で示すように大きく撓み変形して衝突体Ｋへの衝撃を緩和することができる。   In the present embodiment, in the radiator support upper member 12 which is disposed along the vehicle width direction above the front portion of the vehicle body and the hood lock 36 is fixed to the rear wall portion 12C via the hood lock bracket 34, the radiator support upper member. As shown in FIG. 2, the collision body K is formed on the front portion 52A of the hood 52 from the front upper side of the vehicle body to the rear lower side of the vehicle body. In the case of a collision in the side direction (the direction of arrow A in FIG. 2), the radiator support upper member 12 is easily bent from the collision body abutting portion and at the front upper side of the vehicle body as indicated by a two-dot chain line in FIG. The vehicle body deforms from the vehicle body toward the lower rear direction (the direction of arrow B in FIG. 2). As a result, the front portion 52A of the hood 52 can be greatly bent and deformed as shown by a two-dot chain line in FIG.

また、本実施形態では、従来配設されていたラジエータサポートアッパメンバ１２の車幅方向中央部とフロントクロスメンバ４０の車幅方向中央部とを連結するセンタブレースが配設されていないため、この点においても、ラジエータサポートアッパメンバ１２が衝突体当接部を起点に容易に折れ曲がり、衝突体Ｋへの衝撃を緩和することができる。   Further, in the present embodiment, since the center lace that connects the center portion in the vehicle width direction of the radiator support upper member 12 and the center portion in the vehicle width direction of the front cross member 40 that are conventionally provided is not provided, Also at the point, the radiator support upper member 12 can be easily bent from the collision body abutting portion, and the impact on the collision body K can be reduced.

一方、衝突時でない通常状態での車体上方（図１の矢印Ｃ方向）からのフード５２への入力荷重に対しては、フードロック３６がフードロックブラケット３４を介して固定されたラジエータサポートアッパメンバ１２の後壁部１２Ｃが車体垂直方向に立設されていると共に、ラジエータサポートアッパメンバ１２の側断面形状を車体前方斜め上方側が開く開断面とする開口部２０、２２を形成したことで、ラジエータサポートアッパメンバ１２における上方からの荷重を最も確実に支持できる位置である剪断中心Ｌが後壁部１２Ｃの後方となり、この剪断中心Ｌ上にフードロック３６を配設することができる。この結果、衝突時でない通常状態での車体上方（図１の矢印Ｃ方向）からのフード５２への入力荷重に対しては、ラジエータサポートアッパメンバ１２は容易に変形しない。   On the other hand, a radiator support upper member in which a hood lock 36 is fixed via a hood lock bracket 34 against an input load to the hood 52 from above the vehicle body (in the direction of arrow C in FIG. 1) in a normal state not during a collision. 12 has a rear wall portion 12C that is erected in the vertical direction of the vehicle body, and that the radiator support upper member 12 has openings 20 and 22 that have an open cross section that opens obliquely upward on the front side of the vehicle body. The shear center L, which is the position where the load from above on the support upper member 12 can be most reliably supported, is located behind the rear wall portion 12C, and the hood lock 36 can be disposed on the shear center L. As a result, the radiator support upper member 12 is not easily deformed with respect to an input load applied to the hood 52 from above the vehicle body (in the direction of arrow C in FIG. 1) in a normal state not during a collision.

このため、本実施形態の車体前部構造では、衝突体Ｋの衝撃緩和とフード入力荷重に対する剛性確保の両立ができる。   For this reason, in the vehicle body front part structure of the present embodiment, it is possible to achieve both the relaxation of the impact of the collision body K and the securing of rigidity against the hood input load.

以上に於いては、本発明を特定の実施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、本発明の範囲内にて他の種々の実施形態が可能であることは当業者にとって明らかである。例えば、ラジエータサポートアッパメンバ１２の側面視断面形状は、上記実施形態の断面形状に限定されず、車体前方斜め上方側が開く開断面であれば他の断面形状であっても良い。また、開口部２０、２２の形状及び個数も上記実施形態の形状及び個数に限定されない。   Although the present invention has been described in detail with respect to specific embodiments, the present invention is not limited to the above-described embodiments, and various other embodiments are possible within the scope of the present invention. It will be apparent to those skilled in the art. For example, the cross-sectional shape of the radiator support upper member 12 in a side view is not limited to the cross-sectional shape of the above-described embodiment, and may be another cross-sectional shape as long as it is an open cross section that opens obliquely upward on the front side of the vehicle body. Further, the shape and the number of the openings 20 and 22 are not limited to the shape and the number in the above embodiment.
