Description

本発明は、骨格構成部材として車両前後方向に延びるサイドメンバを備えた車体を構成する車体前部構造に関する。   The present invention relates to a vehicle body front structure that constitutes a vehicle body including a side member that extends in the vehicle longitudinal direction as a skeleton component member.

従来、下記特許文献１に開示されているような車体前部構造が、キャブオーバー型と称されるタイプの車両等において採用されている。この車体前部構造は、前後方向水平に延びるフロントサイドメンバにアッパメンバを設けることにより構成されている。この車体前部構造においては、ダッシュパネル上部が客室側に侵入することを防止すべく、アッパメンバに形成された傾斜部の前端と、その直下のフロントサイドメンバとを上下方向に架けわたす連結部材を設けている。これにより、衝突等により車体前部に衝撃が作用した場合に、アッパメンバの位置がサイドメンバの変形後の位置よりも車両後方側にならないような変形モードによって変形するように変形態様をコントロールしようとしている。   2. Description of the Related Art Conventionally, a vehicle body front part structure as disclosed in Patent Document 1 below has been adopted in a vehicle or the like called a cab over type. This vehicle body front structure is configured by providing an upper member on a front side member extending horizontally in the front-rear direction. In this vehicle body front structure, in order to prevent the upper part of the dash panel from entering the passenger compartment, a connecting member that hangs the front end of the inclined part formed on the upper member and the front side member directly below the upper part is provided. Provided. As a result, when an impact is applied to the front part of the vehicle body due to a collision or the like, the deformation mode is controlled so that the upper member is deformed in a deformation mode in which the position of the upper member is not on the vehicle rear side with respect to the position after the deformation of the side member. Yes.

特許第４０６９８３３号公報Japanese Patent No. 4069833

しかしながら、上述した従来技術の車体前部構造は、アッパメンバを備えた車両において採用できるに過ぎず、アッパメンバを備えていない車両においては適用できないという問題がある。また、従来技術の車体前部構造は、衝突等による衝撃が車体前方から後方に向けて作用した際に、アッパメンバとフロントサイドメンバとが共に変形し、ダッシュパネル全体が客室側に後退してくるため、乗員の下肢へのダメージを回避できないという問題がある。   However, there is a problem that the above-described prior art vehicle body front structure can only be employed in a vehicle having an upper member and cannot be applied to a vehicle not having an upper member. In addition, when the impact due to a collision or the like acts from the front to the rear of the vehicle body, the upper member and the front side member are deformed together, and the entire dash panel moves backward toward the passenger compartment. Therefore, there is a problem that damage to the occupant's lower limbs cannot be avoided.

そこで、本発明は、車両前部が変形するような衝撃を受けたとしても、乗員の下肢に与えるダメージを最小限に抑制可能でありつつ、構成がシンプルな車両前部構造の提供を目的とした。   Therefore, the present invention has an object to provide a vehicle front structure having a simple configuration while being capable of minimizing damage to an occupant's lower limb even when subjected to an impact that deforms the vehicle front. did.

上述した課題を解決すべく提供される本発明の車両前部構造は、客室を構成するフロア面よりも下方側において車体前後方向へ延びるように配置されたサイドメンバと、前記フロア面よりも上方側で客室内に乗車した乗員のつま先側の高さに配置され、客室前壁の外面から前方に突出するハット型の断面形状を有する車幅方向に延びたアッパリインフォースとを有し、前記サイドメンバの前端は、前記アッパリインフォースの前端と車両前後方向に略同じ位置又は車両後方側に位置し、前記サイドメンバにおいて車両前端側に到来する部位に、車両前方から後方への衝撃の作用に伴い他の部位よりも車両後方側に向けて圧縮変形しやすい圧縮変形領域が設けられており、車両前方から後方への衝撃の作用に伴う前記サイドメンバの変位量が、前記アッパリインフォースの変位量よりも相対的に大きくなることを特徴とするものである。 The vehicle front structure of the present invention provided to solve the above-described problems includes a side member disposed so as to extend in the vehicle front-rear direction on the lower side of the floor surface constituting the cabin, and above the floor surface. And an appli reinforcement extending in the vehicle width direction having a hat-shaped cross-sectional shape, which is disposed at a height on the toe side of an occupant riding in the passenger compartment on the side and protrudes forward from the outer surface of the passenger compartment front wall, The front end of the member is located at substantially the same position in the vehicle front-rear direction as the front end of the appli-inforce or at the rear side of the vehicle, and the side member comes to the front end side of the vehicle due to an impact from the front to the rear of the vehicle. A compression deformation region that is easily compressed and deformed toward the vehicle rear side than the other part is provided, and the displacement amount of the side member accompanying the action of the impact from the vehicle front to the rear is Serial than the displacement amount of the upper reinforcement is characterized in that relatively large.

本発明の車両前部構造においては、サイドメンバの車両前端側の位置に圧縮変形領域が設けられている。また、圧縮変形領域は、サイドメンバをなす他の部位よりも圧縮変形しやすい領域とされている。このような構成とすることにより、衝突等による衝撃が作用した際に、サイドメンバをアッパリインフォース（構造部材）よりも相対的に大きく変位させることが可能となる。従って、車両前部構造が変形するような衝撃を受けたとしても、乗員の足に対してつま先側がかかと側よりも車両後方側に押し曲げられるような過大な荷重（モーメント）が作用することを抑制し、乗員の下肢に与えるダメージを低減することが可能となる。 In the vehicle front structure according to the present invention, a compression deformation region is provided at a position of the side member on the vehicle front end side. In addition, the compression deformation region is a region that is more easily compressed and deformed than other portions constituting the side member. With such a configuration, when an impact due to a collision or the like is applied, the side member can be displaced relatively larger than the upper reinforcement (structural member) . Therefore, even if the vehicle front structure is subjected to an impact that deforms, an excessive load (moment) is exerted on the occupant's foot so that the toe side is pushed and bent toward the vehicle rear side rather than the heel side. It is possible to suppress and reduce damage to the occupant's lower limbs.

また、本発明の車体前部構造を構成する構造部材は、上述した従来技術の車体前部構造におけるアッパメンバあるいはこれに相当する部材に限定されるものではなく、他の部材であっても良い。そのため、本発明の車体前部構造においては、必ずしもアッパメンバあるいはこれに相当する部材を設ける必要がない。また、本発明の車体前部構造においては、上述した従来技術のものに用いられている連結部材に相当する部材を必要としない。そのため、本発明の車体前部構造を採用することにより、車両構成を簡素化し、車両重量の軽量化、及び燃費特性の向上に資することが可能となる。   Further, the structural member constituting the vehicle body front part structure of the present invention is not limited to the upper member or the member corresponding thereto in the vehicle body front part structure of the prior art described above, and may be another member. Therefore, in the vehicle body front part structure of the present invention, it is not always necessary to provide an upper member or a member corresponding thereto. Moreover, in the vehicle body front part structure of the present invention, a member corresponding to the connecting member used in the above-described prior art is not required. Therefore, by adopting the vehicle body front structure of the present invention, the vehicle configuration can be simplified, the vehicle weight can be reduced, and the fuel consumption characteristics can be improved.

本発明によれば、車両前部が変形するような衝撃を受けたとしても、乗員の下肢に与えるダメージを最小限に抑制可能でありつつ、構成がシンプルな車両前部構造を提供することができる。   ADVANTAGE OF THE INVENTION According to this invention, even if it receives the impact which a vehicle front part deform | transforms, it can suppress the damage given to a passenger | crew's leg, and can provide a vehicle front structure with a simple structure. it can.

以下、本発明の一実施形態に係る車両前部構造１０について、図面を参照しつつ詳細に説明する。図１に示すように、本実施形態の車体前部構造１０は、フルキャブ型、あるいはキャブオーバー型等と称されるタイプの自動車の前方部分をなす構造である。車体前部構造１０は、客室１２の底部側に乗員の下肢が配置される客室足下空間２０を有する。   Hereinafter, a vehicle front structure 10 according to an embodiment of the present invention will be described in detail with reference to the drawings. As shown in FIG. 1, the vehicle body front structure 10 of the present embodiment is a structure that forms the front portion of a type of vehicle called a full cab type or a cab over type. The vehicle body front part structure 10 has a cabin foot space 20 in which the occupant's lower limbs are arranged on the bottom side of the cabin 12.

図２（ａ）に示すように、客室足下空間２０の車両前方側には客室前壁３０が設けられている。客室前壁３０は、客室１２の前方側において立設された壁面である。具体的には、ダッシュパネル、あるいはこれに相当する壁面が客室前壁３０に該当する。図２（ａ）に示すように、客室前壁３０は、客室１２の床面をなすフロアパネル４０側の部分をなす下壁部３２と、これよりも上方側の部分をなす上壁部３４とに大別される。   As shown in FIG. 2A, a guest room front wall 30 is provided on the vehicle front side of the guest room foot space 20. The guest room front wall 30 is a wall surface standing on the front side of the guest room 12. Specifically, a dash panel or a wall surface corresponding thereto corresponds to the front wall 30 of the passenger room. As shown in FIG. 2A, the guest room front wall 30 includes a lower wall part 32 that forms a floor panel 40 side part that forms the floor surface of the guest room 12, and an upper wall part 34 that forms a part on the upper side. It is roughly divided into

また、下壁部３２は、上方に向かうに連れて車両前方側に向かうように傾斜した前傾部３８を有する。これにより、客室前壁３０は、下壁部３２において、車両前方側に向けて膨出した形状とされている。従って、図２（ａ）に示すように、乗員は、自身の足を下壁部３２の前傾部３８に沿って配置することができる。   Moreover, the lower wall part 32 has the front inclination part 38 which inclined so that it might go to a vehicle front side as it went upwards. Thereby, the passenger compartment front wall 30 has a shape that bulges toward the vehicle front side in the lower wall portion 32. Accordingly, as shown in FIG. 2A, the occupant can place his / her foot along the forward inclined portion 38 of the lower wall portion 32.

上壁部３４は、下壁部３２に対して上方に繋がる壁面である。上壁部３４は、下壁部３２の上端から、客室１２の前方に設けられたフロントウィンドー１４の下端側において車幅方向に延びるように設けられたカウル、あるいはこれに相当する部材に至る部分を構成している。   The upper wall portion 34 is a wall surface connected upward with respect to the lower wall portion 32. The upper wall portion 34 extends from the upper end of the lower wall portion 32 to a cowl provided to extend in the vehicle width direction on the lower end side of the front window 14 provided in front of the cabin 12 or a member corresponding thereto. Make up part.

また、図２（ａ）に示すように、客室足下空間２０の下方側にはフロアパネル４０が設けられている。また、図１及び図２に示すように、フロアパネル４０の下方には、車両前後方向に延びる一対のサイドメンバ５０，５０が、車幅方向に間隔を開けて配置されている。すなわち、サイドメンバ５０，５０は、客室１２内に乗車した乗員のかかと側の高さに配置されている。   Further, as shown in FIG. 2A, a floor panel 40 is provided on the lower side of the cabin foot space 20. As shown in FIGS. 1 and 2, a pair of side members 50, 50 extending in the vehicle front-rear direction are disposed below the floor panel 40 with an interval in the vehicle width direction. That is, the side members 50 and 50 are disposed at a height on the heel side of the occupant who gets in the passenger compartment 12.

サイドメンバ５０，５０の先端側（車両前端側）には、車両前方から後方への衝撃の作用に伴い他の部位よりも車両後方側に向けて圧縮変形しやすい圧縮変形領域５２，５２が設けられている。圧縮変形領域５２，５２の大きさは、適宜設定することが可能であるが、本実施形態においては、図２（ａ）に示すように客室前壁３０をなす下壁部３２とフロアパネル４０との接合端４２，４２あるいはこの近傍を基準として、これよりも車両前方側に突出した部分を圧縮変形領域５２，５２としている。言い換えれば、客室前壁３０において、乗員の足が配置されるであろう下壁部３２の前傾部３８の下方側に圧縮変形領域５２，５２が形成されている。   On the front end side (vehicle front end side) of the side members 50, 50 are provided compression deformation regions 52, 52 that are more easily compressed and deformed toward the vehicle rear side than the other parts due to the impact from the vehicle front to the rear. It has been. The size of the compression deformation regions 52, 52 can be set as appropriate. In the present embodiment, as shown in FIG. 2A, the lower wall portion 32 and the floor panel 40 forming the front wall 30 of the passenger cabin. With reference to the joint ends 42, 42 or the vicinity thereof, the portions projecting further forward than the vehicle are defined as compression deformation regions 52, 52. In other words, on the front wall 30 of the passenger compartment, the compression deformation regions 52 and 52 are formed below the forward inclined portion 38 of the lower wall portion 32 where the occupant's feet are to be disposed.

圧縮変形領域５２，５２は、種々の方策により形成することが可能であるが、本実施形態においては他の部位よりも板厚を薄くすることにより形成されている。圧縮変形領域５２，５２は、衝突等に伴って車両前方部に作用する過剰に大きな衝撃を、圧縮変形することにより吸収することを目的として設けられている。   Although the compression deformation regions 52 and 52 can be formed by various measures, in the present embodiment, the compression deformation regions 52 and 52 are formed by making the plate thickness thinner than other portions. The compression deformation regions 52 and 52 are provided for the purpose of absorbing an excessively large impact acting on the front portion of the vehicle due to a collision or the like by compressing and deforming.

また、上述したフロアパネル４０及びサイドメンバ５０，５０よりも上方側には、アッパリインフォース７０（構造部材）が設けられている。アッパリインフォース７０は、いわゆるハット型の断面形状を有する部材である。アッパリインフォース７０は、客室前壁３０の外面（客室１２に対して外側の面）から前方に突出し、下壁部３２及び上壁部３４の境界部分近傍において、車幅方向に延びるように設けられている。アッパリインフォース７０は、客室１２内に乗車した乗員のつま先側の高さに設けられている。
Further, an upper reinforcement 70 (structural member) is provided above the floor panel 40 and the side members 50, 50 described above. The appli reinforcement 70 is a member having a so-called hat-shaped cross-sectional shape. The appli reinforcement 70 protrudes forward from the outer surface of the passenger compartment front wall 30 (the outer surface relative to the passenger compartment 12) , and is provided to extend in the vehicle width direction in the vicinity of the boundary between the lower wall portion 32 and the upper wall portion 34. ing. The appli reinforcement 70 is provided at the height of the toe side of the passenger who gets in the passenger compartment 12.

本実施形態の車両前部構造１０は、衝突等に伴い、車両前方から後方に向かう方向に向けて過剰に大きな衝撃が作用した場合の挙動において特徴を有する。具体的には、車両前部に衝突等に伴う衝撃が作用すると、図２（ｂ）に示すように、サイドメンバ５０，５０の圧縮変形領域５２，５２が軸方向（車両前後方向）に圧縮変形し、変位する。また、衝突等の衝撃により、アッパリインフォース７０が車両後方側（客室１２側）に向けて変位した状態になる。   The vehicle front structure 10 according to the present embodiment is characterized in behavior when an excessively large impact is applied in a direction from the front of the vehicle toward the rear due to a collision or the like. Specifically, when an impact due to a collision or the like acts on the front portion of the vehicle, the compression deformation regions 52 and 52 of the side members 50 and 50 are compressed in the axial direction (vehicle longitudinal direction) as shown in FIG. Deforms and displaces. Further, due to impact such as a collision, the appli reinforcement 70 is displaced toward the vehicle rear side (the cabin 12 side).

ここで、上述したように、サイドメンバ５０，５０の圧縮変形領域５２，５２は、他の部位よりも圧縮変形しやすく成形されていることから、図２（ｂ）に示すように圧縮変形による変位量Ａが大きい。これに対し、アッパリインフォース７０の変位量Ｂは、サイドメンバ５０，５０の変位量Ａに比べて小さい。そのため、衝突等に伴う衝撃が作用することにより車両前部構造１０が圧縮変形したとしても、アッパリインフォース７０が相対的にサイドメンバ５０，５０よりも車両前方側である相対的な位置関係が維持される。これにより、客室足下空間２０に配置された乗員の足に対し、図２（ｂ）において矢印Ｍで示すような無理なモーメントが作用することを抑制できる。従って、車両前部構造１０によれば、乗員の下肢に与えるダメージを低減することが可能となる。   Here, as described above, the compression deformation regions 52 and 52 of the side members 50 and 50 are formed so as to be more easily compressed and deformed than other portions, and therefore, as shown in FIG. The displacement amount A is large. On the other hand, the displacement amount B of the applier reinforcement 70 is smaller than the displacement amount A of the side members 50 and 50. Therefore, even when the vehicle front structure 10 is compressed and deformed due to an impact caused by a collision or the like, the relative positional relationship in which the Appli reinforcement 70 is relatively on the front side of the vehicle with respect to the side members 50 and 50 is maintained. Is done. Thereby, it is possible to suppress an unreasonable moment acting as shown by an arrow M in FIG. 2B on the occupant's feet arranged in the cabin foot space 20. Therefore, according to the vehicle front portion structure 10, it is possible to reduce damage to the occupant's lower limbs.

また、車体前部構造１０においては、従来技術のようにアッパリインフォース７０とサイドメンバ５０，５０とを連結する連結部材等を必要としない。そのため、車体前部構造１０を採用することにより車両構成の簡素化を図り、車両重量の軽量化、及び燃費特性の向上に資することが可能となる。   Further, the vehicle body front structure 10 does not require a connecting member or the like for connecting the appli reinforcement 70 and the side members 50 and 50 as in the prior art. Therefore, by adopting the vehicle body front part structure 10, it is possible to simplify the vehicle configuration, contribute to reducing the vehicle weight and improving the fuel consumption characteristics.

本実施形態では、サイドメンバ５０，５０に対して上方側に位置し、客室足下空間２０に配置された乗員のつま先側に位置する構造部材として、アッパリインフォース７０を配置した例を示したが、本発明はこれに限定されるものではない。すなわち、アッパリインフォース７０に代えて、他の構造部材を用いることも可能である。   In the present embodiment, an example in which the appli reinforcement 70 is arranged as a structural member located on the upper side with respect to the side members 50 and 50 and located on the toe side of the occupant arranged in the cabin foot space 20 has been shown. The present invention is not limited to this. That is, it is possible to use other structural members in place of the Appli reinforcement 70.

本実施形態では、サイドメンバ５０，５０の圧縮変形領域５２，５２を、他の部位よりも板厚を薄くすることにより構成した例を示したが、本発明はこれに限定されるものではない。具体的には、圧縮変形領域５２，５２に、サイドメンバ５０，５０の軸方向への圧縮変形を促進するための開口、サイドメンバ５０，５０の長手方向（車両前後方向）に対して交差する方向に延びるビード、切り欠き、あるいは溝等のように脆弱化させるための構成（脆弱化構成）を設けた構成としても良い。また、開口、ビード、切り欠き、あるいは溝等の脆弱化構成を複数種設けること、あるいは他の部分より板厚を薄くすることに加えて開口等の脆弱化構成を設けることとしても良い。   In this embodiment, although the example which comprised the compression deformation area | regions 52 and 52 of the side members 50 and 50 by making plate | board thickness thinner than another site | part was shown, this invention is not limited to this. . Specifically, the compression deformation regions 52 and 52 intersect with the opening for promoting the compression deformation in the axial direction of the side members 50 and 50 and the longitudinal direction of the side members 50 and 50 (vehicle longitudinal direction). It is good also as a structure which provided the structure (weakening structure) for weakening like a bead, a notch, or a groove | channel extended in a direction. Moreover, it is good also as providing weakening structures, such as opening, in addition to providing multiple types of weakening structures, such as an opening, a bead, a notch, or a groove | channel, or making plate thickness thinner than another part.

本実施形態においては、客室前壁３０の下壁部３２の下端側に、上方に向かうに連れて車両前方側に向かうように傾斜した前傾部３８を設けた例を示したが、本発明はこれに限定される訳ではない。具体的には、下壁部３２は、図３（ａ）に示すようにフロアパネル４０に対して略垂直なものとされても良い。このような構成とした場合についても、上述した通り、フロアパネル４０の下方に配されるサイドメンバ５０，５０の先端部に圧縮変形領域５２，５２を設け、図３（ｂ）に示すように車両前方から後方への衝撃の作用に伴うサイドメンバ５０，５０の変位量Ａが、アッパリインフォース７０の変位量Ｂよりも相対的に大きくなるようにしておくことにより、乗員の足首に無理なモーメントが作用することを抑制し、下肢を保護することが可能となる。   In the present embodiment, an example has been shown in which a forward inclined portion 38 is provided on the lower end side of the lower wall portion 32 of the guest room front wall 30 so as to be inclined toward the vehicle front side as it goes upward. Is not limited to this. Specifically, the lower wall portion 32 may be substantially perpendicular to the floor panel 40 as shown in FIG. Also in the case of such a configuration, as described above, the compression deformation regions 52, 52 are provided at the front ends of the side members 50, 50 arranged below the floor panel 40, as shown in FIG. By making the displacement amount A of the side members 50 and 50 due to the impact from the front to the rear of the vehicle relatively larger than the displacement amount B of the applier reinforcement 70, an excessive moment is applied to the occupant's ankle. It is possible to suppress the action of and protect the lower limbs.

本実施形態においては、車体前部構造１０を、フルキャブ型、あるいはキャブオーバー型等と称されるタイプの自動車に適用した例を示したが、本発明はこれに限定されるものではなく、他のタイプの自動車にも適用することが可能である。   In the present embodiment, an example in which the vehicle body front structure 10 is applied to a vehicle of a type referred to as a full cab type or a cab over type has been described, but the present invention is not limited to this. It can be applied to other types of vehicles.

本発明は、客室内に乗車した乗員のつま先側の高さに設けられた構造部材と、かかと側の高さにおいて車体前後方向へ延びるように配置されたサイドメンバとを備えた車両全般に適用可能であり、特にフルキャブ型、あるいはキャブオーバー型等と称されるタイプの自動車において好適に利用可能である。   The present invention is applied to all vehicles including a structural member provided at a toe side height of an occupant riding in a passenger cabin, and a side member arranged to extend in the longitudinal direction of the vehicle body at a heel side height. In particular, the present invention can be suitably used in an automobile of a type called a full cab type or a cab over type.
