Description

本発明は、乗用車や商用車、トラックやバス等の車両において、車両の前部構造に関する。   The present invention relates to a vehicle front structure in a vehicle such as a passenger car, a commercial vehicle, a truck, or a bus.

車両では例えば特許文献１に開示されているように、車体の前部の右及び左側部に車体前後方向に沿って配置されるサイドメンバー（特許文献１の図１及び図２中の１２）、車体の前部の車体左右方向に沿って配置されるクロスメンバー（特許文献１の図１及び図２中の１３）を備えて、サイドメンバーの前部にクロスメンバーの横部を連結したものが多くある。
特許文献１の構造では、Ａピラー（特許文献１の図１及び図２中の１４）の下部から、骨格部材（特許文献１の図１及び図２中の１６）を前方斜め下方に延出して、サイドメンバーと骨格部材とを、連結部材（特許文献１の図１及び図２中の１７，１８，２１）を介して連結している。 In a vehicle, for example, as disclosed in Patent Document 1, side members (12 in FIG. 1 and FIG. 2 in Patent Document 1) disposed along the front-rear direction of the vehicle body on the right and left sides of the front portion of the vehicle body, A cross member (13 in FIG. 1 and FIG. 2 of Patent Document 1) arranged along the left-right direction of the vehicle body at the front part of the vehicle body, and a lateral part of the cross member connected to the front part of the side member. There are many.
In the structure of Patent Document 1, a skeleton member (16 in FIGS. 1 and 2 of Patent Document 1) is extended forward and obliquely downward from the lower portion of the A pillar (14 in FIGS. 1 and 2 of Patent Document 1). Then, the side member and the skeleton member are connected via a connecting member (17, 18, 21 in FIGS. 1 and 2 of Patent Document 1).

特開２００３−４０１４２号公報（図１及び図２）Japanese Patent Laying-Open No. 2003-40142 (FIGS. 1 and 2)

車両では一般に、前面からの衝突の際に、主にサイドメンバーが破壊されることによって衝突のエネルギーが吸収されるのであり、衝突のエネルギーがサイドメンバーに集中的に掛かる傾向がある。この場合、サイドメンバーによる衝突のエネルギーの吸収には限界があるので、できるだけ衝突のエネルギーがサイドメンバーに集中的に掛からないように構成することが必要である。   In general, in the case of a collision from the front, the collision energy is absorbed mainly by the destruction of the side member, and the collision energy tends to be concentrated on the side member. In this case, since the absorption of collision energy by the side member is limited, it is necessary to configure so that the collision energy is not concentrated on the side member as much as possible.

特許文献１の構造によると、サイドメンバー（特許文献１の図１及び図２中の１２）とは別に、骨格部材（特許文献１の図１及び図２中の１６）を備えることにより、衝突のエネルギーがサイドメンバーばかりではなく、骨格部材にも掛かるように構成している。しかしながら、サイドメンバーと骨格部材とが互いに離れた位置にあるので、衝突のエネルギーがサイドメンバーばかりではなく骨格部材にも掛かるようにすると言う面で、改善の余地がある。
本発明は車両の前部構造において、前面からの衝突の際に、衝突のエネルギーがサイドメンバーに集中的に掛かる状態を避けることができるように構成することを目的としており、別の車両との前面からの衝突の際に、衝突のエネルギーが別の車両の部分に集中的に掛かる状態を避けることができるように構成することを目的としている。 According to the structure of Patent Document 1, by providing a skeleton member (16 in FIGS. 1 and 2 of Patent Document 1) separately from the side member (12 in FIGS. 1 and 2 of Patent Document 1), the collision The energy is applied not only to the side members but also to the skeleton members. However, since the side member and the skeleton member are located away from each other, there is room for improvement in terms of causing the collision energy to be applied not only to the side member but also to the skeleton member.
The object of the present invention is to make it possible to avoid a state in which the energy of the collision is concentrated on the side member in the case of a collision from the front surface in the front structure of the vehicle. An object of the present invention is to make it possible to avoid a state in which the energy of the collision is concentrated on another vehicle portion in the event of a collision from the front.

本発明の第１特徴は、車両の前部構造において次のように構成することにある。
車体の前部の右及び左側部に車体前後方向に沿って配置されるサイドメンバーと、車体の前部の車体左右方向に沿って配置されるクロスメンバーとを備える。サイドメンバーの上方で前輪のタイヤハウスを形成するエプロン部と、エプロン部に連結されて下方に延出された連結メンバーとを備える。サイドメンバーの前部の前面とクロスメンバーの横部の前面と連結メンバーの下部の前面とが、車体前後方向の略同じ位置で互いに連なって略同一面となるように、サイドメンバーの前部とクロスメンバーの横部と連結メンバーの下部とを互いに連結する。 [I]
(Constitution)
The first feature of the present invention resides in the following configuration in the vehicle front structure.
A side member arranged along the vehicle body longitudinal direction on the right and left sides of the front part of the vehicle body and a cross member arranged along the vehicle body left-right direction of the vehicle body front part are provided. An apron portion that forms a tire house of a front wheel above the side member, and a connecting member that is connected to the apron portion and extends downward. The front part of the side member and the front part of the side member so that the front part of the front part of the side member, the front part of the side part of the cross member and the front part of the lower part of the connecting member are connected to each other at substantially the same position in the longitudinal direction of the vehicle body. The horizontal part of the cross member and the lower part of the connecting member are connected to each other.

（作用）
本発明の第１特徴によると、サイドメンバーの前部とクロスメンバーの横部と連結メンバーの下部とを互いに連結しており、サイドメンバーの前部の前面とクロスメンバーの横部の前面と連結メンバーの下部の前面が、車体前後方向の略同じ位置で互いに連なって略同一面となるように構成しているのであり、サイドメンバーの前部の前面とクロスメンバーの横部の前面と連結メンバーの下部の前面が、比較的広い面積を備えた受け面となっている。 (Function)
According to the first aspect of the present invention, the front part of the side member, the lateral part of the cross member, and the lower part of the connecting member are connected to each other, and connected to the front surface of the front part of the side member and the front surface of the lateral part of the cross member. The front of the lower part of the member is configured so that they are connected to each other at substantially the same position in the longitudinal direction of the vehicle body so as to be substantially the same surface, the front of the front of the side member, the front of the side of the cross member, and the connecting member. The lower front surface of this is a receiving surface with a relatively large area.

Is in a state where it is dispersed and applied to each part of the connecting member, the collision energy is also applied to the apron part via the connecting member, and the collision energy is absorbed also in the apron part. .

本発明の第１特徴によると、サイドメンバーの前部の前面とクロスメンバーの横部の前面と連結メンバーの下部の前面が、比較的広い面積を備えた受け面となっているので、別の車両との前面からの衝突の際に、衝突のエネルギーが前述の広い面積を備えた受け面を介して別の車両に掛かる状態となるのであり、衝突のエネルギーが前述の広い面積を備えた受け面により別の車両に分散して掛かるような状態を得ることができる（例えば、衝突のエネルギーがサイドメンバーの前部から別の車両の部分に集中的に掛かって、サイドメンバーが別の車両の部分に入り込むような状態を避けることができる）。   According to the first feature of the present invention, the front surface of the front portion of the side member, the front surface of the lateral portion of the cross member, and the front surface of the lower portion of the connecting member are receiving surfaces having a relatively large area. In the case of a collision from the front with the vehicle, the collision energy is applied to another vehicle via the receiving surface having the aforementioned large area, and the collision energy is received by the aforementioned large area. It is possible to obtain a state in which the vehicle is distributed to another vehicle depending on the surface (for example, the collision energy is concentrated on another vehicle part from the front of the side member, and the side member is To avoid getting into the part).
