Description

本発明は車両用バンパ構造に関し、特に、自動車等の車両において衝突体を検知する車両用バンパ構造に関する。   The present invention relates to a vehicular bumper structure, and more particularly to a vehicular bumper structure that detects a collision object in a vehicle such as an automobile.

従来から、自動車等の車両において衝突体を検知する車両用バンパ構造においては、バンパリインフォースメントの前面に長手方向に延びる溝を形成し、この溝内に衝突検知センサを収納すると共に、衝撃吸収材の後面に上下一対の溝を形成し、衝突検知センサに対する押込み部を形成した構成が知られている（例えば、特許文献１参照）。
特開２０００−２２５９０７号公報 Conventionally, in a vehicle bumper structure for detecting a collision object in a vehicle such as an automobile, a groove extending in the longitudinal direction is formed on the front surface of the bumper reinforcement, and a collision detection sensor is accommodated in the groove, and an impact absorbing material. A configuration is known in which a pair of upper and lower grooves are formed on the rear surface, and a pushing portion for a collision detection sensor is formed (see, for example, Patent Document 1).
JP 2000-225907 A

しかしながら、特許文献１では、衝突検知センサを配設したバンパリインフォースメントの前壁部とバンパリインフォースメント後壁部との間に空間が形成されている。この結果、衝突検知センサの取付け位置の剛性が低い。このため、荷重作用時に衝突検知センサが車体後方側へ移動し易く安定した検出ができなくなり、衝突検知性能が低下する。   However, in Patent Document 1, a space is formed between the front wall portion of the bumper reinforcement where the collision detection sensor is disposed and the rear wall portion of the bumper reinforcement. As a result, the rigidity of the mounting position of the collision detection sensor is low. For this reason, the collision detection sensor easily moves to the rear side of the vehicle body when a load is applied, so that stable detection cannot be performed, and the collision detection performance is deteriorated.

本発明は上記事実を考慮し、衝突検知性能を向上できる車両用バンパ構造を提供することが目的である。   An object of the present invention is to provide a vehicle bumper structure that can improve the collision detection performance in consideration of the above facts.

請求項１記載の本発明の車両用バンパ構造は、車幅方向に沿って延設され、閉断面部を有する側断面形状とされたバンパリインフォースメントと、
前記閉断面部内に車体前後方向に沿って配設された補強部と、
前記補強部の車体外側となる前記バンパリインフォースメントの車体外側面に配設された衝突検知センサと、
を有することを特徴とする。 A bumper reinforcement for a vehicle according to a first aspect of the present invention includes a bumper reinforcement that extends along the vehicle width direction and has a side cross-sectional shape having a closed cross-sectional portion;
A reinforcing portion disposed along the longitudinal direction of the vehicle body in the closed cross-sectional portion;
A collision detection sensor disposed on a vehicle body outer surface of the bumper reinforcement that is on the vehicle body outside of the reinforcing portion;
It is characterized by having.

従って、衝突体がバンパに衝突した場合には、外部からの荷重が衝突検知センサに伝達される。この際、衝突検知センサが配設されたバンパリインフォースメントの車体外側面の車体内側には、バンパリインフォースメントの閉断面部内の車体前後方向に沿った補強部が配設されている。この結果、衝突検知センサの取付け位置の剛性が高くなっている。このため、荷重作用時に衝突検知センサが車体内側へ移動し難く安定した荷重検出ができるので、衝突検知性能を向上できる。   Therefore, when the collision body collides with the bumper, a load from the outside is transmitted to the collision detection sensor. At this time, a reinforcing portion along the longitudinal direction of the vehicle body in the closed cross section of the bumper reinforcement is disposed inside the vehicle body outer surface of the bumper reinforcement where the collision detection sensor is disposed. As a result, the rigidity of the attachment position of the collision detection sensor is high. For this reason, since the collision detection sensor is difficult to move to the inside of the vehicle body when the load is applied and stable load detection can be performed, the collision detection performance can be improved.

また、請求項２記載の本発明は、請求項１に記載の車両用バンパ構造において、前記衝突検知センサを前記バンパリインフォースメントの上下方向中央より上方側に設けたことを有することを特徴とする。   According to a second aspect of the present invention, in the vehicular bumper structure according to the first aspect, the collision detection sensor is provided above the center in the vertical direction of the bumper reinforcement. .

従って、請求項１に記載の内容に加えて、衝突検知センサをバンパリインフォースメントの上下方向中央より上方側に設けたため、衝突体がバンパにおけるバンパリインフォースメントの上下方向中央より上方側に当接した場合には、衝突体がバンパにおけるバンパリインフォースメントの上下方向中央より下方側に当接した場合に比べて検知性能が向上する。この結果、衝突体がバンパの上方側に当接した場合の衝突検知性能を向上できる。   Therefore, in addition to the content described in claim 1, since the collision detection sensor is provided above the center in the vertical direction of the bumper reinforcement, the collision body abuts above the center in the vertical direction of the bumper reinforcement in the bumper. In this case, the detection performance is improved as compared with the case where the colliding body is in contact with the lower side of the bumper reinforcement in the bumper reinforcement in the vertical direction. As a result, it is possible to improve the collision detection performance when the collision body contacts the upper side of the bumper.

請求項１記載の本発明の車両用バンパ構造は、車幅方向に沿って延設され、閉断面部を有する側断面形状とされたバンパリインフォースメントと、閉断面部内に車体前後方向に沿って配設された補強部と、補強部の車体外側となるバンパリインフォースメントの車体外側面に配設された衝突検知センサと、を有するため、衝突検知性能を向上できるという優れた効果を有する。   The bumper structure for a vehicle according to the first aspect of the present invention includes a bumper reinforcement that extends in the vehicle width direction and has a side cross-sectional shape having a closed cross-sectional portion, and a vehicle body longitudinal direction in the closed cross-sectional portion. Since it has the reinforcement part arrange | positioned and the collision detection sensor arrange | positioned in the vehicle body outer side surface of the bumper reinforcement used as the vehicle body outer side of a reinforcement part, it has the outstanding effect that a collision detection performance can be improved.

また、請求項２記載の本発明は、請求項１に記載の車両用バンパ構造において、衝突検知センサをバンパリインフォースメントの上下方向中央より上方側に設けたため、請求項１に記載の効果に加えて、衝突体がバンパの上方側に当接した場合の衝突検知性能を向上できるという優れた効果を有する。   In addition, the present invention described in claim 2 provides the vehicle bumper structure described in claim 1, wherein the collision detection sensor is provided above the center in the vertical direction of the bumper reinforcement. Thus, it has an excellent effect of improving the collision detection performance when the colliding body comes into contact with the upper side of the bumper.

Further, the side cross-sectional shape of the bumper reinforcement 20 is a closed cross-sectional portion that is divided into three in the vertical direction by ribs 20A and 20B as reinforcing portions formed along the vehicle longitudinal direction with a predetermined interval in the vehicle vertical direction. 24 has a square shape.

バンパリインフォースメント２０の前壁部２０Ｃの前面における、上方側のリブ２０Ａの車体外側（前側）となる部位には、衝突検知センサとしてのバンパタッチセンサ２６が車幅方向に沿って配設されており、バンパタッチセンサ２６は、バンパリインフォースメントの上下方向中央Ｑより上方側に設けられている。   A bumper touch sensor 26 as a collision detection sensor is disposed along the vehicle width direction at a portion of the front wall portion 20C of the bumper reinforcement 20 on the front side of the upper rib 20A. The bumper touch sensor 26 is provided above the center Q in the vertical direction of the bumper reinforcement.

図２に示される如く、バンパタッチセンサ２６は帯状のブラケット２７を介してバンパリインフォースメント２０の前壁部２０Ｃに両面テープ等によって固定されており、バンパタッチセンサ２６は、例えば、Ｈｉ／Ｌｏｗ出力のスイッチタイプのセンサで構成されている。   As shown in FIG. 2, the bumper touch sensor 26 is fixed to the front wall portion 20C of the bumper reinforcement 20 via a strip-shaped bracket 27 with double-sided tape or the like. The bumper touch sensor 26 is, for example, a Hi / Low output. It is composed of switch type sensors.

図１に示される如く、バンパリインフォースメント２０とバンパタッチセンサ２６との車体外側（車体前側）となる部位、即ち、バンパリインフォースメント２０またはバンパタッチセンサ２６と、バンパカバー１４との間には、衝撃吸収材としてのバンパアブソーバフォーム３０が配設されている。   As shown in FIG. 1, a portion of the bumper reinforcement 20 and the bumper touch sensor 26 that is outside the vehicle body (front side of the vehicle body), that is, between the bumper reinforcement 20 or the bumper touch sensor 26 and the bumper cover 14, A bumper absorber foam 30 as an impact absorbing material is disposed.

また、バンパアブソーバフォーム３０の後壁部には、車体上下方向に所定の間隔を開けて凸部３０Ａ、３０Ｂ、３０Ｃ、３０Ｄが車体内側（車体後側）に向って形成されており、上下方向中間部の凸部３０Ｂ、３０Ｃが、バンパタッチセンサ２６の上下近傍においてバンパリインフォースメント２０の前壁部２０Ｃに当接している。   Further, on the rear wall portion of the bumper absorber foam 30, convex portions 30A, 30B, 30C, and 30D are formed toward the vehicle body inner side (vehicle body rear side) at predetermined intervals in the vehicle body vertical direction. The intermediate convex portions 30 </ b> B and 30 </ b> C are in contact with the front wall portion 20 </ b> C of the bumper reinforcement 20 in the vicinity of the bumper touch sensor 26.

なお、バンパアブソーバフォーム３０の後壁部における凸部３０Ｂと凸部３０Ｃとの間の部位３０Ｅとバンパタッチセンサ２６との隙間３２は狭くなっている。   A gap 32 between the bumper touch sensor 26 and the portion 30E between the convex portion 30B and the convex portion 30C in the rear wall portion of the bumper absorber form 30 is narrow.

一方、凸部３０Ａ、３０Ｂ、３０Ｃ、３０Ｄのうち上側の凸部３０Ａと下側の凸部３０Ｄはバンパリインフォースメント２０における前壁部２０Ｃの上縁部２０Ｄとその近傍及び下縁部２０Ｅとその近傍とにそれぞれ当接している。   On the other hand, among the convex portions 30A, 30B, 30C, and 30D, the upper convex portion 30A and the lower convex portion 30D are the upper edge portion 20D of the front wall portion 20C in the bumper reinforcement 20, the vicinity thereof, and the lower edge portion 20E.

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、図４に示すように、衝突体Ｋ１がフロントバンパ１２に衝突した場合には、図３に示される如く、衝突体Ｋ１によって、フロントバンパ１２のバンパカバー１４とともにバンパアブソーバフォーム３０が車体前方側から車体後方側に向かって押圧される。この結果、バンパアブソーバフォーム３０の後壁部における凸部３０Ｂと凸部３０Ｃとの間の部位３０Ｅがバンパタッチセンサ２６に当接し、外部からの荷重Ｆがバンパタッチセンサ２６に伝達される。   In the present embodiment, as shown in FIG. 4, when the collision body K1 collides with the front bumper 12, the bumper absorber foam 30 together with the bumper cover 14 of the front bumper 12 is caused by the collision body K1 as shown in FIG. Is pressed from the front side of the vehicle body toward the rear side of the vehicle body. As a result, a portion 30E between the convex portion 30B and the convex portion 30C in the rear wall portion of the bumper absorber foam 30 comes into contact with the bumper touch sensor 26, and the load F from the outside is transmitted to the bumper touch sensor 26.

この際、本実施形態では、バンパリインフォースメント２０の前壁部２０Ｃにおける、上方側のリブ２０Ａの車体外側（車体前側）となる部位にバンパタッチセンサ２６が車幅方向に沿って配設されている。即ち、バンパタッチセンサ２６が配設されたバンパリインフォースメント２０の前壁部２０Ｃの車体内側（車体後側）には、バンパリインフォースメント２０の閉断面部２４内の車体前後方向に沿ったリブ２０Ａが配設されている。   At this time, in the present embodiment, the bumper touch sensor 26 is disposed along the vehicle width direction at a portion of the front wall portion 20C of the bumper reinforcement 20 that is on the vehicle body outside (vehicle body front side) of the upper rib 20A.

Is arranged.

この結果、本実施形態では、バンパタッチセンサ２６の取付け位置の剛性が高くなっている。このため、本実施形態では、荷重作用時にバンパタッチセンサ２６が車体後方側へ移動し難く安定した荷重検出ができるので、衝突検知性能を向上できる。   As a result, in this embodiment, the rigidity of the mounting position of the bumper touch sensor 26 is high. For this reason, in the present embodiment, the bumper touch sensor 26 is difficult to move to the rear side of the vehicle body when a load is applied, and stable load detection can be performed, so that the collision detection performance can be improved.

また、図４に示される如く、衝突体Ｋ１がフロントバンパ１２の上方側に衝突した場合には、図３に示される如く、バンパアブソーバフォーム３０の上方側が押圧される。この際、本実施形態では、バンパタッチセンサ２６が、バンパリインフォースメント２０の上下方向中央Ｑより上方側に設けられている。この結果、バンパアブソーバフォーム３０の後壁部における凸部３０Ｂと凸部３０Ｃとの間の部位３０Ｅがバンパタッチセンサ２６に当接し、外部からの荷重Ｆがバンパタッチセンサ２６に伝達される。   As shown in FIG. 4, when the collision body K1 collides with the upper side of the front bumper 12, the upper side of the bumper absorber foam 30 is pressed as shown in FIG. At this time, in this embodiment, the bumper touch sensor 26 is provided above the center Q in the vertical direction of the bumper reinforcement 20. As a result, a portion 30E between the convex portion 30B and the convex portion 30C in the rear wall portion of the bumper absorber foam 30 comes into contact with the bumper touch sensor 26, and the load F from the outside is transmitted to the bumper touch sensor 26.

一方、図６に示される如く、衝突体Ｋ２がフロントバンパ１２の下方側に衝突した場合には、図５に示される如く、バンパアブソーバフォーム３０の下方側が押圧される。この際、本実施形態では、バンパタッチセンサ２６が、バンパリインフォースメント２０の上下方向中央Ｑより上方側に設けられている。この結果、バンパアブソーバフォーム３０の後壁部における凸部３０Ｂと凸部３０Ｃとの間の部位３０Ｅは、バンパタッチセンサ２６に当接せず、外部からの荷重Ｆがバンパタッチセンサ２６に伝達されない。   On the other hand, as shown in FIG. 6, when the collision body K2 collides with the lower side of the front bumper 12, the lower side of the bumper absorber foam 30 is pressed as shown in FIG. At this time, in this embodiment, the bumper touch sensor 26 is provided above the center Q in the vertical direction of the bumper reinforcement 20. As a result, the portion 30E between the convex portion 30B and the convex portion 30C in the rear wall portion of the bumper absorber foam 30 does not contact the bumper touch sensor 26, and the load F from the outside is not transmitted to the bumper touch sensor 26. .

従って、本実施形態では衝突体Ｋ１がフロントバンパ１２におけるバンパリインフォースメント２０の上下方向中央Ｑより上方側に当接した場合には、衝突体Ｋ２がフロントバンパ１２におけるバンパリインフォースメント２０の上下方向中央Ｑより下方側に当接した場合に比べて検知性能が向上する。このため、衝突体がフロントバンパ１２の上方側に当接した場合の衝突検知性能を向上できる。   Therefore, in this embodiment, when the collision body K1 is in contact with the upper side in the vertical direction Q of the bumper reinforcement 20 in the front bumper 12, the collision body K2 is in the vertical direction center of the bumper reinforcement 20 in the front bumper 12. The detection performance is improved as compared with the case of contacting the lower side than Q. For this reason, it is possible to improve the collision detection performance when the collision body contacts the upper side of the front bumper 12.
