Description

本発明は、車体の前部構造に関する。   The present invention relates to a front structure of a vehicle body.

従来より、自動車の車体前部構造は、車体の前端部で車幅方向に延設されてボンネットフードを支持するアッパーバーと、アッパーバーの下方で車幅方向に延設されるフロントエンドクロスメンバロアと、上下方向に延設されてアッパーバーとフロントエンドクロスメンバロアとを連結する一対のランプサポートとで構成されている。そして、アッパーバーは、ランプサポートとの接合箇所を除いて矩形等の閉断面で形成され、ランプサポートとの接合箇所が平板状の開断面で形成されている。   2. Description of the Related Art Conventionally, an automobile body front structure includes an upper bar that extends in the vehicle width direction at the front end of the vehicle body and supports the hood hood, and a front end cross member that extends in the vehicle width direction below the upper bar. And a pair of lamp supports that extend in the vertical direction and connect the upper bar and the front end cross member lower. The upper bar is formed with a closed cross section such as a rectangle except for the joint portion with the lamp support, and the joint portion with the lamp support is formed with a flat plate-shaped open cross section.

そして、アッパーバーには、ボンネットフードを閉じた際に上方から荷重が加わる。特に荷重は、アッパーバーの車幅方向中央部に設けられるラッチ機構に作用する。そして、アッパーバーは、車幅方向両端部をランプサポートで支持されているため、ボンネットフードからの荷重を受けると車幅方向中央部が下方に撓むとともにアッパーバーに捩りモーメントが発生する。上記の構成のようにランプサポートとの接合箇所が平板状の閉断面で形成されていると、アッパーバーの接合箇所での剛性が他部位より不足するために、アッパーバーの車幅方向中央部と両端部の接合箇所とで捻りモーメントに対する耐力が不均一となりアッパーバーのランプサポートとの接合箇所に応力が集中することとなる。このため、荷重が繰り返し作用するとアッパーバーが接合箇所で変形する虞がある。よって、接合箇所でのアッパーバーの変形を抑制するために、アッパーバーの板厚を増加したり、補強部材を設けたりして接合箇所での剛性及び強度を確保している。   A load is applied to the upper bar from above when the hood is closed. In particular, the load acts on a latch mechanism provided at the center of the upper bar in the vehicle width direction. Since the upper bar is supported by lamp supports at both ends in the vehicle width direction, when receiving a load from the bonnet hood, the center portion in the vehicle width direction is bent downward and a torsional moment is generated in the upper bar. If the joint part with the lamp support is formed in a flat plate-like closed section as in the above configuration, the rigidity at the joint part of the upper bar is insufficient compared to other parts. Therefore, the yield strength against torsional moment is uneven at the joints at both ends, and stress is concentrated at the joints with the lamp support of the upper bar. For this reason, when a load acts repeatedly, there exists a possibility that an upper bar may change in a joined part. Therefore, in order to suppress the deformation of the upper bar at the joint location, the plate thickness of the upper bar is increased or a reinforcing member is provided to ensure the rigidity and strength at the joint location.

しかしながら、アッパーバーのような板金部材は、部分的に板厚を厚くすることができないため、アッパーバー全体の板厚を増加しなければならない、また、補強部材を設けると部品点数が増加してしまうという問題があり、どちらも車体重量及びコストの増加に繋がっていた。また、特許文献１のように車体の前端部上部のアッパーバーに相当する部材を長方形の閉断面に形成されたパイプ状として、接合箇所における剛性を確保しているものがある。   However, since the sheet metal member such as the upper bar cannot be partially thickened, it is necessary to increase the plate thickness of the entire upper bar. Also, if the reinforcing member is provided, the number of parts increases. Both have led to an increase in the weight and cost of the vehicle. In addition, as disclosed in Patent Document 1, there is a member that secures rigidity at a joint portion by forming a member corresponding to the upper bar at the upper portion of the front end of the vehicle body into a pipe shape formed in a rectangular closed cross section.

このように、アッパーバーの全てを閉断面で形成し、断面強度を確保すれば、接合箇所における剛性が向上され、アッパーバーの変形を抑制することができる。   Thus, if all of the upper bar is formed with a closed cross section and the cross sectional strength is ensured, the rigidity at the joint location is improved and the deformation of the upper bar can be suppressed.

特開２００９−１５４５５６号公報JP 2009-154556 A

ところで近年、車体重量を軽減して燃費の向上を図るため部材の板厚が薄肉化される傾向にある。そして、アッパーバーも例外ではなく薄肉化が図られているが、板厚を薄肉化すると、部材の強度や剛性が低下することとなる。
上記特許文献１の車体前部構造では、長方形の閉断面に形成された上部のパイプ材（アッパーバーに相当）の下面にそれぞれ車体上下方向に延伸するパイプ材（ランプサポートに相当）を接合している。 By the way, in recent years, in order to reduce the weight of the vehicle body and improve the fuel consumption, the thickness of the member tends to be reduced. Further, the upper bar is not an exception and is made thinner. However, when the plate thickness is made thinner, the strength and rigidity of the member are lowered.
In the vehicle body front structure disclosed in Patent Document 1, pipe materials (corresponding to lamp supports) extending in the vehicle body vertical direction are respectively joined to the lower surface of an upper pipe material (corresponding to an upper bar) formed in a rectangular closed cross section. ing.

このような構造では、ボンネットフードを閉じた際の荷重は、上部のパイプ材（アッパーバー）の車両前後双方の縦壁（側面）を介して下面に接合されたパイプ材（ランプサポート）に伝達されるため、簿肉化されると強度を十分に確保できずに接合箇所において上部のパイプ材（アッパーバー）の前後の縦壁（側面）が荷重により変形してしまう虞がある。   In such a structure, the load when the hood is closed is transmitted to the pipe material (lamp support) joined to the lower surface via the vertical walls (side surfaces) of the upper pipe material (upper bar) on both front and rear sides of the vehicle. For this reason, when it is made into a book, sufficient strength cannot be ensured, and the vertical walls (side surfaces) of the upper pipe material (upper bar) at the joint location may be deformed by a load.

したがって、特許文献１のような構造では、荷重による縦壁（側面）の変形を防止するために、部分的に補強するなどの対策が必要となる場合があった。
即ち、従来の車体前部構造では、軽量化と強度の確保の両立が困難であった。
本発明は、この様な問題を解決するためになされたもので、その目的とするところは、重量及びコストが増加することなく、強度を確保することのできる車体前部構造を提供することにある。 Therefore, in a structure like patent document 1, in order to prevent the deformation | transformation of the vertical wall (side surface) by a load, measures, such as partial reinforcement, were needed.
That is, in the conventional vehicle body front part structure, it is difficult to achieve both weight reduction and ensuring strength.
The present invention has been made to solve such problems, and an object of the present invention is to provide a vehicle body front structure that can ensure strength without increasing weight and cost. is there.

また、請求項３の車体構造では、請求項１或いは２において、前記アッパー部材は、アッパーバー上部とアッパーバー下部とを有し、少なくとも前記サポート部材との結合部における断面が、前記アッパーバー上部と前記アッパーバー上部に対して前記アッパーバー下部が鋭角を成して傾斜する傾斜面部とを備えた閉断面に形成されることを特徴とする。
また、請求項４の車体前部構造では、請求項１乃至３のいずれか１項において、前記アッパー部材は、前記傾斜面部の上端と下端とからそれぞれフランジ部が延設され、それぞれの前記フランジ部が前記サポート部材の前記接合面の上下で結合されることを特徴とする。 Further, in the vehicle body front part structure according to claim 2, in claim 1, the closed cross section at the coupling portion of the upper member is erected in any one of the upper surface portion, the inclined surface portion, and the vehicle body longitudinal direction. It is characterized by being formed in a triangular shape composed of side portions.
Further, in the vehicle body structure of claim 3, in claim 1 or 2, the upper member has an upper bar upper portion and an upper bar lower portion, and at least a cross section at a joint portion with the support member has an upper bar upper portion. The lower portion of the upper bar is formed in a closed cross section having an inclined surface portion inclined at an acute angle with respect to the upper portion of the upper bar.

Moreover, in the invention of claim 2, the closed cross section at the coupling portion of the upper member is formed in a triangular shape. Therefore, since the triangular shape has a strong cross-sectional strength, it is not necessary to increase the thickness for securing the strength.

また、請求項３の発明では、アッパー部材の傾斜面部の上端と下端とからそれぞれフランジ部が延設され、それぞれのフランジ部がサポート部材の接合面の上下で結合している。
このように、サポート部材との結合箇所をアッパー部材の傾斜面部の上端と下端からそれぞれ延設されるフランジ部として、アッパー部材を非同一平面に結合することで結合箇所の捩り剛性を向上させることができる。 In the invention of claim 3, the flange portions are respectively extended from the upper end and the lower end of the inclined surface portion of the upper member, and the respective flange portions are coupled above and below the joint surface of the support member.
Thus, the torsional rigidity of the coupling portion is improved by coupling the upper member to a non-coplanar surface by using the coupling portion with the support member as a flange portion extending from the upper end and the lower end of the inclined surface portion of the upper member, respectively.
