Description

この発明は、自動車等の車両の車体構造、とりわけ車体前部の車体構造に関するものである。   The present invention relates to a vehicle body structure of a vehicle such as an automobile, and more particularly to a vehicle body structure at the front of a vehicle body.

従来から車室の前壁を形成するダッシュロアパネルの下部側は、車両前面衝突時に後方に変位しないように板厚を増加したり、パッチを貼り付けて変形し難いようになっている。また、ダッシュロアパネルの下部側にクロスメンバを配置したものがある（例えば、特許文献１参照）。
特開平１１−２０８５０５号公報 Conventionally, the lower side of the dash lower panel forming the front wall of the passenger compartment has been difficult to be deformed by increasing the plate thickness or attaching a patch so as not to be displaced rearward in the event of a vehicle front collision. In addition, there is one in which a cross member is arranged on the lower side of the dash lower panel (see, for example, Patent Document 1).
JP-A-11-208505

しかしながら、前者にあっては車体重量が増加して燃費向上に逆行するという問題がある。また、後者においてはクロスメンバにより剛性を確保しているため、ダッシュロアパネル自体の強度剛性をアップする必要はないが、車両衝突時にダッシュロアパネルが変形をすると、乗員の足元のスペースが狭くなるため、このスペースを確保するためには車体前部を長くする必要があり、車体のショートオーバーハング化を図れず、造形上の自由度が低下するという問題がある。   However, in the former, there is a problem that the weight of the vehicle body increases and the fuel efficiency is improved. Moreover, in the latter, since the rigidity is secured by the cross member, there is no need to increase the strength and rigidity of the dash lower panel itself, but if the dash lower panel is deformed at the time of a vehicle collision, the space at the foot of the occupant becomes narrower. In order to secure this space, it is necessary to lengthen the front part of the vehicle body, and there is a problem that the vehicle body cannot be short-overhanged and the degree of freedom in modeling is reduced.

そこで、この発明は、ダッシュボード部の下部の剛性を向上すると共に、衝撃荷重に対する変形を最小限に抑えることができる車体構造を提供するものである。   Therefore, the present invention provides a vehicle body structure capable of improving the rigidity of the lower portion of the dashboard portion and minimizing deformation with respect to an impact load.

上記目的を達成するために、請求項１に記載した発明は、ダッシュボード部（例えば、実施形態におけるダッシュロアパネル３の前壁部４）とフロア部（例えば、実施形態におけるダッシュロアパネル３の延出部５、クロスメンバ６の張り出し部７及びフロアパネル８）とで形成するコーナ部（例えば、実施形態におけるコーナ部１０）近傍に、左右のサイドフレーム（例えば、実施形態におけるサイドフレーム２１）間に渡りクロスメンバ（例えば、実施形態におけるクロスメンバ６）を設け、クロスメンバ内に隔壁（例えば、実施形態におけるバルクヘッド２２）を配置すると共にクロスメンバ後部とフロア部とを連結するサポート部材（例えば、実施形態におけるサポート部材３３）を配置し、このサポート部材の一端をクロスメンバの前記隔壁配置部位に連結することを特徴とする。
このように構成することで、隔壁により強度剛性を高めたクロスメンバを更にサポート部材により支持して車両前側からの荷重に対して対抗できるようにした。 In order to achieve the above object, the invention described in claim 1 includes a dashboard portion (for example, the front wall portion 4 of the dash lower panel 3 in the embodiment) and a floor portion (for example, extension of the dash lower panel 3 in the embodiment). Between the left and right side frames (for example, the side frame 21 in the embodiment) in the vicinity of the corner portion (for example, the corner portion 10 in the embodiment) formed by the portion 5, the projecting portion 7 of the cross member 6 and the floor panel 8). A cross member (for example, the cross member 6 in the embodiment) is provided, a partition member (for example, the bulkhead 22 in the embodiment) is disposed in the cross member, and a support member (for example, a cross member is connected to the floor portion) The support member 33) in the embodiment is disposed, and one end of the support member is connected to the cross member. Characterized in that connected to the partition wall placement site.
With this configuration, the cross member whose strength and rigidity are enhanced by the partition wall is further supported by the support member so that it can counter the load from the front side of the vehicle.

請求項２に記載した発明は、前記ダッシュボード部の下部であってクロスメンバの前方に、車室内側に膨出する隆起部（例えば、実施形態における隆起部５１）を設けたことを特徴とする。
このように構成することで、車両前側からの荷重により車体部材が後方に移動しても、隆起部により後方に位置するダッシュボード部には至らず、ダッシュボード部の変形を回避できる。 The invention described in claim 2 is characterized in that a raised portion (for example, the raised portion 51 in the embodiment) that bulges toward the vehicle interior side is provided in the lower portion of the dashboard portion and in front of the cross member. To do.
With this configuration, even if the vehicle body member moves rearward due to a load from the front side of the vehicle, the dashboard portion does not reach the rear portion due to the raised portion, and deformation of the dashboard portion can be avoided.

請求項１に記載した発明によれば、隔壁により強度剛性を高めたクロスメンバを更にサポート部材により支持して車両前側からの荷重に対して対抗できるようにしたため、軽量化を図ることができる効果がある。   According to the first aspect of the present invention, the cross member whose strength and rigidity are enhanced by the partition wall is further supported by the support member so as to be able to counter the load from the front side of the vehicle, and thus the weight can be reduced. There is.

請求項２に記載した発明によれば、車両前側からの荷重により車体部材が後方に移動しても、隆起部により後方に位置するダッシュボード部には至らず、ダッシュボード部の変形を回避できる。よって、車体前部に移動ストロークを確保するための長いスペースが必要なくなり、ショートオーバーハング化が可能となって車体造形上の自由度を高めることができる効果がある。   According to the second aspect of the present invention, even if the vehicle body member moves rearward due to a load from the front side of the vehicle, the raised portion does not reach the dashboard portion positioned rearward, and deformation of the dashboard portion can be avoided. . Therefore, there is no need for a long space for securing a moving stroke in the front part of the vehicle body, and there is an effect that a short overhang can be realized and the degree of freedom in vehicle body modeling can be increased.

以下、この発明の実施形態を図面と共に説明する。

Therefore, the side frames 21 and 21 forming the vehicle body skeleton members on both sides of the vehicle body are closed cross sections formed by the cross members 6 and the extensions arranged in the vehicle width direction on the lower surfaces of the floor panel 8 and the dash lower panel 3. It will be connected with a structure part.

前記クロスメンバ６の内部、具体的には前壁１１、後壁１２及び両側壁１３，１３で囲まれた部分には隔壁であるバルクヘッド２２が一対取り付けられている。このバルクヘッド２２は主壁２３面を左右に向けて配置されるものである。この主壁２３にはクロスメンバ６の前壁１１に溶接接合される前フランジ部２４、クロスメンバ６の底壁９に溶接接合される下フランジ部２５、クロスメンバ６の後壁１２に溶接接合される後フランジ部２６が形成され、上記一対のバルクヘッド２２が各々長手方向を前後に向け左右方向に所定間隔を隔てて取り付けられている。ここで、各バルクヘッド２２は同一形状に形成され、主壁２３には軽量化のために孔２７が形成されている。   A pair of bulkheads 22 which are partition walls are attached to the inside of the cross member 6, specifically, a portion surrounded by the front wall 11, the rear wall 12 and both side walls 13 and 13. The bulkhead 22 is arranged with the main wall 23 facing left and right. The main wall 23 is welded to the front flange portion 24 welded to the front wall 11 of the cross member 6, the lower flange portion 25 welded to the bottom wall 9 of the cross member 6, and the rear wall 12 of the cross member 6 welded to the main wall 23. A rear flange portion 26 is formed, and the pair of bulkheads 22 are attached to each other with a predetermined interval in the left-right direction with the longitudinal direction facing forward and backward. Here, each bulkhead 22 is formed in the same shape, and a hole 27 is formed in the main wall 23 for weight reduction.

そして、バルクヘッド２２の主壁２３の上縁にはフランジ部２８が形成されている。ここで、前記フランジ部２８の前端部にはクロスメンバ６の前壁１１上縁に溶接接合される縦フランジ３０が設けられ、フランジ部２８の後縁部には前記クロスメンバ６の延出部５のフランジ部１６に設けた接合部３１に溶接接合される後フランジ部３２が形成されている。このように構成されたバルクヘッド２２が取り付けられた状態で、クロスメンバ６がダッシュロアパネル３の延出部５の裏面に接合されている。   A flange portion 28 is formed on the upper edge of the main wall 23 of the bulkhead 22. Here, a vertical flange 30 welded to the upper edge of the front wall 11 of the cross member 6 is provided at the front end portion of the flange portion 28, and the extending portion of the cross member 6 is provided at the rear edge portion of the flange portion 28. A rear flange portion 32 that is welded to a joint portion 31 provided on the flange portion 16 is formed. The cross member 6 is joined to the back surface of the extending portion 5 of the dash lower panel 3 with the bulkhead 22 configured as described above being attached.

図３に示すように、クロスメンバ６の張り出し部７とクロスメンバ６の後部としての後壁１２とに渡る部位には、下側からサポート部材３３が溶接接合されている。このサポート部材３３は前記バルクヘッド２２の配置部位に対応して一対取り付けられるものであり、前記バルクヘッド２２の主壁２３の位置に一致する主壁部３４を備えている。つまり、このサポート部材３３の前端（一端）はクロスメンバ６の前記バルクヘッド２２の配置部位に連結されることとなる。そして、サポート部材３３の主壁部３４には前記クロスメンバ６の後壁１２に溶接接合される前部フランジ部３５が形成され、主壁部３４の上縁にはクロスメンバ６の張り出し部７に裏側から溶接接合される２つのフランジ片３６，３６が形成されている。   As shown in FIG. 3, a support member 33 is welded from below to a portion of the cross member 6 that extends between the protruding portion 7 and the rear wall 12 as the rear portion of the cross member 6. A pair of support members 33 are attached corresponding to the arrangement site of the bulkhead 22, and include a main wall portion 34 that coincides with the position of the main wall 23 of the bulkhead 22. That is, the front end (one end) of the support member 33 is connected to the arrangement site of the bulkhead 22 of the cross member 6. A front flange portion 35 is formed on the main wall portion 34 of the support member 33 by welding to the rear wall 12 of the cross member 6, and the protruding portion 7 of the cross member 6 is formed on the upper edge of the main wall portion 34. Two flange pieces 36, 36 which are welded and joined from the back side are formed.

図２、図４に示すように前記ダッシュロアパネル３の延出部５の上面にはエアバック等の衝突安全装置の機能部品を取り付けるための取付ブラケット４０が取り付けられている。この取付ブラケット４０は、車幅方向に延びるベース部４１に後方に向かって延びる２つの舌状部４２，４３を備えたものであり、ベース部４１の前縁には前記ダッシュロアパネル３の延出部５に接合される前縁フランジ４４，４４が設けられている。前記右側の舌状部４３には前記延出部５に接合される後縁フランジ部４５が形成され、左側の舌状部４２の後部側縁には前記延出部５に接合される側縁フランジ部４６，４６が形成されている。   As shown in FIGS. 2 and 4, a mounting bracket 40 for mounting a functional component of a collision safety device such as an air bag is mounted on the upper surface of the extending portion 5 of the dash lower panel 3. The mounting bracket 40 includes a base portion 41 extending in the vehicle width direction and two tongue-like portions 42 and 43 extending rearward. The dash lower panel 3 extends at the front edge of the base portion 41. Leading edge flanges 44, 44 joined to the part 5 are provided. The right tongue portion 43 is formed with a rear edge flange portion 45 joined to the extension portion 5, and the rear edge of the left tongue portion 42 is a side edge joined to the extension portion 5. Flange portions 46, 46 are formed.

ここで、右側の舌状部４３には後部傾斜面４７が形成され、この後部傾斜面４７にはステアリングハンガーセンターフレーム１８の取付孔４８が形成されている。
このように構成された、取付ブラケット４０の取付孔４８と前記クロスメンバ６の張り出し部７の凸部１７の取付孔１９，１９にステアリングハンドルを支持するステアリングハンガーセンターフレーム１８の脚部４９（図３にのみ示す）が図示しないボルトにより締め付け固定されるようになっている。尚、取付ブラケット４０にはベース部４１の左後部にも延出部に接合されるフランジ部５０が形成されている。 Here, a rear inclined surface 47 is formed in the right tongue 43, and a mounting hole 48 of the steering hanger center frame 18 is formed in the rear inclined surface 47.
The leg portion 49 of the steering hanger center frame 18 that supports the steering handle in the mounting hole 48 of the mounting bracket 40 and the mounting holes 19 and 19 of the convex portion 17 of the projecting portion 7 of the cross member 6 constructed as described above. (Only shown in 3) is fastened and fixed by a bolt (not shown). The mounting bracket 40 is also formed with a flange portion 50 which is joined to the extending portion at the left rear portion of the base portion 41.

そして、前記ダッシュロアパネル３の下部であって、クロスメンバ６の前方に位置する部位には車室内側に膨出する隆起部５１が形成され、この隆起部５１の前方にアクティブエンジンマウント５２が配置されている。ここで、このアクティブエンジンマウント５２はエンジン振動を油圧等により動的に調整するための比較的重量の大きい機能部品である。したがって、アクティブエンジンマウント５２からダッシュロアパネル３までの間には隆起部５１によってアクティブエンジンマウント５２が後方に移動した場合の移動ストロークＳが確保されることとなる。   A raised portion 51 that bulges toward the vehicle interior side is formed at a lower portion of the dash lower panel 3 and in front of the cross member 6. An active engine mount 52 is disposed in front of the raised portion 51. Has been. Here, the active engine mount 52 is a functional component having a relatively large weight for dynamically adjusting engine vibration by hydraulic pressure or the like. Therefore, a movement stroke S is secured between the active engine mount 52 and the dash lower panel 3 when the active engine mount 52 moves rearward by the raised portion 51.

上記実施形態によれば、前記バルクヘッド２２により強度剛性が高められたクロスメンバ６を更にサポート部材３３により支持したため、車両の前面衝突時に車両前側から作用する荷重に対してバルクヘッド２２の主壁２３、サポート部材３３の主壁部３４により強度的に有利な縦方向でこれを受けて対抗することができる。したがって、効果的に入力荷重に対抗することができるため補強のために板厚を増加したり、多くの補強部材を使用したりする必要がなくなりその分だけ車体軽量化を図ることができる。また、このクロスメンバ６に支持されているステアリングハンガーセンターフレーム１８の支持剛性を高めることができる。   According to the above embodiment, since the cross member 6 whose strength and rigidity are enhanced by the bulkhead 22 is further supported by the support member 33, the main wall of the bulkhead 22 against the load acting from the front side of the vehicle at the time of frontal collision of the vehicle. 23, the main wall 34 of the support member 33 can receive and oppose it in the longitudinal direction which is advantageous in strength. Accordingly, since it is possible to effectively resist the input load, it is not necessary to increase the plate thickness for reinforcement or use many reinforcing members, and the vehicle weight can be reduced correspondingly. Further, the support rigidity of the steering hanger center frame 18 supported by the cross member 6 can be increased.

ところで、前記車両前面衝突時に車体前部が後方に移動することによりアクティブエンジンマウント５２が後方に移動しても、隆起部５１によりアクティブエンジンマウント５２の後方への移動ストロークＳを充分に確保しているため、アクティブエンジンマウント５２によりダッシュロアパネル３が変形するのを確実に防止することができる。
よって、車体前部に前記移動ストロークＳを確保するための長いスペースが必要なくなるので、車体のショートオーバーハング化が可能となって車体造形上の自由度を高めることができる。 By the way, even when the active engine mount 52 moves rearward due to the rearward movement of the vehicle body at the time of the front collision of the vehicle, the bulging portion 51 sufficiently secures the moving stroke S to the rear of the active engine mount 52. Therefore, it is possible to reliably prevent the dash lower panel 3 from being deformed by the active engine mount 52.
This eliminates the need for a long space for securing the moving stroke S at the front portion of the vehicle body, thereby enabling a short overhang of the vehicle body and increasing the degree of freedom in modeling the vehicle body.

このようにして、強度剛性を高めたクロスメンバ６に前側からの入力荷重に対抗する機能とステアリングハンガーセンターフレーム１８を支持する機能とを併せ持たせると共に、ダッシュロアパネル３に隆起部５１を設けて、車両衝突時の乗員の足元回りのスペースを確保することができるのである。つまり、ダッシュボード部の下部の強度剛性を向上すると共に衝撃荷重に対する変形を最小限に食い止めることができる車体構造を実現できるのである。   In this way, the cross member 6 with increased strength and rigidity has both the function of resisting the input load from the front side and the function of supporting the steering hanger center frame 18, and the raised portion 51 is provided on the dash lower panel 3. Thus, it is possible to secure a space around the occupant's feet when the vehicle collides. That is, it is possible to realize a vehicle body structure that can improve the strength and rigidity of the lower portion of the dashboard portion and can minimize deformation against an impact load.

また、前記クロスメンバ６には張り出し部７を設けてあり、この張り出し部７をサポート部材３３で補強し、ここにステアリングハンガーセンターフレーム１８を支持したため、フロアパネル８にトンネル部を設けこのトンネル部にステアリングハンガーセンターフレームを取り付ける構造に比較して、フロアパネル８を軽量化できる点で有利である。   Further, the cross member 6 is provided with an overhanging portion 7, and this overhanging portion 7 is reinforced by a support member 33 and the steering hanger center frame 18 is supported here, so that a tunnel portion is provided in the floor panel 8 and this tunnel portion. This is advantageous in that the floor panel 8 can be reduced in weight compared to a structure in which the steering hanger center frame is attached to the floor panel 8.
