ところで、バンパリインホースに荷重を受けた場合、バンパリインホースが撓むことにより、バンパリインホースが結合される結合部材（例えば、バンパーステー、クラッシュボックス或いはサイドメンバなど）の稜線又は角と接するバンパリインホースの位置に荷重が集中する。取り付け側の一部に切欠部を有するバンパリインホースの場合、切欠部では荷重を受けることができないため、縦壁に荷重が集中的に加わる。このため、縦壁が変形し、荷重を支えきれない懸念がある。   By the way, when a load is applied to the bumper inn hose, the ridge line or corner of a coupling member (for example, a bumper stay, a crash box, or a side member) to which the bumper inn hose is coupled by bending of the bumper inn hose. The load concentrates on the position of the bumper inhose in contact with the. In the case of a bumper inhose having a notch part on the attachment side, the load cannot be received at the notch part, so that the load is concentrated on the vertical wall. For this reason, there is a concern that the vertical wall is deformed and cannot fully support the load.

本発明の目的は、バンパリインホースの軽量化を図りながら、バンパリインホースに荷重を受けた場合、バンパリインホースとバンパリインホースが結合される結合部材との間に発生する集中的な荷重を減少する車両用バンパ装置を提供することにある。   An object of the present invention is to reduce the weight of a bumper inn hose and to concentrate between the bumper inn hose and a connecting member to which the bumper inn hose is coupled when a load is applied to the bumper inn hose.

A space is provided, and the bumper inhose can be reduced in weight. In addition, since the reinforcing member is provided so as to bridge between the two inner vertical walls at each end, the reinforcing member receives the load received from the ridgeline or corner of the coupling member even when the bumper in hose is bent. Thus, the load on the bumper inn hose can be dispersed and reduced. Moreover, deformation of both inner vertical walls can be prevented.

請求項２に記載の発明は、請求項１に記載の車両用バンパ装置において、前記補強部材の車両幅方向の幅は、前記結合部材の前記補強部材と接する車両幅方向の幅より大きいことを要旨とする。   According to a second aspect of the present invention, in the vehicle bumper device according to the first aspect, the width of the reinforcing member in the vehicle width direction is larger than the width of the coupling member in the vehicle width direction in contact with the reinforcing member.

以下、本発明を具体化した一実施形態を図面に従って説明する。
図１は、自動車などの車両のフロント部分に適用される本実施形態に係る車両用バンパ装置を示す斜視図であり、図２及び図３は、その断面図及び平面図である。なお、図２は、図１のＡ−Ａ線に沿った断面図となっている。図３に示されるように、この車両用バンパ装置は、車両の幅方向両側に配設されてボデーの一部を構成する一対のサイドメンバ１１に、クラッシュボックス（結合部材）１３を介して取り付けられる。各サイドメンバ１１は、例えば金属板からなり、断面略四角形の中空構造を有して車両の前後方向に延びる。 DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, an embodiment of the invention will be described with reference to the drawings.
FIG. 1 is a perspective view showing a vehicle bumper device according to this embodiment applied to a front portion of a vehicle such as an automobile, and FIGS. 2 and 3 are a sectional view and a plan view thereof. 2 is a cross-sectional view taken along the line AA in FIG. As shown in FIG. 3, the vehicle bumper device is attached to a pair of side members 11 that are disposed on both sides in the width direction of the vehicle and constitute a part of the body via a crash box (coupling member) 13. It is done. Each side member 11 is made of, for example, a metal plate, has a hollow structure with a substantially square cross section, and extends in the front-rear direction of the vehicle.

前記各サイドメンバ１１の前端には、該サイドメンバ１１の開口部を閉塞する態様で、例えば金属板からなる略四角形のブラケット１２が溶接にて固着されている。なお、一対のブラケット１２は、ラジエータの支持に供される。   A substantially square bracket 12 made of, for example, a metal plate is fixed to the front end of each side member 11 by welding in a manner that closes the opening of the side member 11. The pair of brackets 12 are used for supporting the radiator.

前記各ブラケット１２の前面には、例えば金属板からなり、車両の前後方向に延びるクラッシュボックス（結合部材）１３が取着されている。このクラッシュボックス１３は、前後方向の中心線が前記サイドメンバ１１の前後方向の中心線と一致するように配置されており、その後端に溶接にて固着されたブラケット１４において、前記ブラケット１２にボルト及びナット（図示略）にて締結されている。一対のクラッシュボックス１３は、加えられた荷重を軸方向の塑性変形で吸収して衝撃エネルギーを吸収する。なお、各クラッシュボックス１３は、軸方向に蛇腹状に塑性変形する。   A crash box (a connecting member) 13 made of, for example, a metal plate and extending in the front-rear direction of the vehicle is attached to the front surface of each bracket 12. The crush box 13 is arranged so that the center line in the front-rear direction coincides with the center line in the front-rear direction of the side member 11, and a bolt 14 is attached to the bracket 12 in a bracket 14 fixed to the rear end by welding. And a nut (not shown). The pair of crash boxes 13 absorbs the impact energy by absorbing the applied load by plastic deformation in the axial direction. Each crash box 13 is plastically deformed in an accordion shape in the axial direction.

前記各クラッシュボックス１３の前端には、該クラッシュボックス１３の開口部を閉塞する態様で、例えば金属板からなるプレート１５が溶接にて固着されるとともに、該プレート１５には、車両の幅方向に延びるバンパリインホース１６の各端部が結合されている。   A plate 15 made of, for example, a metal plate is fixed to the front end of each crash box 13 by welding in a manner that closes the opening of the crash box 13, and is attached to the plate 15 in the vehicle width direction. Each end of the extended bumper-in hose 16 is joined.

詳述すると、図１及び図２に示すように、本実施形態のバンパリインホース１６は、車両幅方向に延在する断面一定の、例えばアルミニウムの押出材からなり、車両前後方向内側が開口したコの字型断面形状の本体部２１及び該本体部２１の開口の上下端から連続する一対の内側フランジ（縦壁）２２を一体的に有する。そして、前記バンパリインホース１６の車両幅方向（長手方向）の各端部には、高さ方向に並設された前記両内側フランジ２２間を橋渡しするように、金属板からなる補強部材２３がボルト及びナットからなる締結手段２４にて締結されている。これら補強部材２３の取着されたバンパリインホース１６は、各端部において前記内側フランジ２２と共に補強部材２３がボルト及びナット（図示略）にて前記プレート１５に締結されることで前記クラッシュボックス１３に支持される。図８に示すように、補強部材２３の車両幅方向の幅Ｂは、クラッシュボックス１３の補強部材２３と接する車両幅方向の幅Ａより大きい。   More specifically, as shown in FIGS. 1 and 2, the bumper-in hose 16 of the present embodiment is made of, for example, an aluminum extruded material having a constant cross section extending in the vehicle width direction, and the inner side in the vehicle front-rear direction is open. The main body 21 having a U-shaped cross-sectional shape and a pair of inner flanges (vertical walls) 22 continuous from the upper and lower ends of the opening of the main body 21 are integrally provided. A reinforcing member 23 made of a metal plate is provided at each end in the vehicle width direction (longitudinal direction) of the bumper inhose 16 so as to bridge between the inner flanges 22 arranged in parallel in the height direction. Are fastened by fastening means 24 comprising bolts and nuts. The bumper-in hose 16 to which the reinforcing members 23 are attached is connected to the plate 15 with bolts and nuts (not shown) together with the inner flange 22 at each end so that the crash box 13 is supported. As shown in FIG. 8, the width B in the vehicle width direction of the reinforcing member 23 is larger than the width A in the vehicle width direction in contact with the reinforcing member 23 of the crash box 13.

ここで、車両の衝突等により前方から衝撃が加えられると、この衝撃は、バンパリインホース１６及びクラッシュボックス１３を介してサイドメンバ１１（ボデー）に伝達される。このとき、バンパリインホース１６とともにクラッシュボックス１３が塑性変形することで、ボデーへ伝達される衝撃を緩衝する。これにより、ボデー及び乗員に加えられる衝撃エネルギーが吸収される。   Here, when an impact is applied from the front due to a vehicle collision or the like, the impact is transmitted to the side member 11 (body) via the bumper-in hose 16 and the crash box 13. At this time, the impact box transmitted to the body is buffered by plastic deformation of the crash box 13 together with the bumper-in hose 16. Thereby, the impact energy applied to the body and the passenger is absorbed.

次に、本実施形態の動作について説明する。既述のように、前記バンパリインホース１６は、その各端部に結合された前記補強部材２３とともに前記クラッシュボックス１３に結合される。この場合、前記バンパリインホース１６の各端部は、前記補強部材２３が結合されることで、内側フランジ２２に加わる荷重が減少されると共に、内側フランジ２２を含むバンパリインホース１６の変形が防止される。なお、本実施形態の補強部材２３は、両内側フランジ２２間に配置される中央部が前側に突出して溝部２３ａを形成しているが、周辺部品（プレート１５等）との干渉を回避し得るのであれば該溝部２３ａを割愛した面一な補強部材であってもよい。   Next, the operation of this embodiment will be described. As described above, the bumper-in hose 16 is coupled to the crash box 13 together with the reinforcing member 23 coupled to each end thereof. In this case, each end portion of the bumper rein hose 16 is coupled to the reinforcing member 23 so that the load applied to the inner flange 22 is reduced, and the bumper rein hose 16 including the inner flange 22 is deformed. Is prevented. In the reinforcing member 23 of the present embodiment, the central portion disposed between the inner flanges 22 protrudes forward to form the groove portion 23a, but interference with peripheral components (plate 15 and the like) can be avoided. In this case, a flat reinforcing member that omits the groove 23a may be used.

また、前記補強部材２３の取着されたバンパリインホース１６は、ポール衝突を想定した３点曲げ評価において優れていることが確認されている。図４は、各種断面形状を有するバンパリインホース１６の変形量（ストローク）に対する荷重の推移を示すグラフである。同図において、前記補強部材２３の取着されたバンパリインホース１６の荷重の推移を実線で、補強部材２３を割愛したバンパリインホース１６単独の荷重の推移を破線でそれぞれ示す。   Moreover, it has been confirmed that the bumper-in hose 16 to which the reinforcing member 23 is attached is excellent in a three-point bending evaluation assuming a pole collision. FIG. 4 is a graph showing the transition of the load with respect to the deformation amount (stroke) of the bumper-in hose 16 having various cross-sectional shapes. In the figure, the transition of the load of the bumper inn hose 16 to which the reinforcing member 23 is attached is indicated by a solid line, and the transition of the load of the bumper inn hose 16 without the reinforcing member 23 is indicated by a broken line.

以上詳述したように、本実施形態によれば、以下に示す効果が得られる。
（１）本実施形態では、前記バンパリインホース１６は、内側フランジ２２間に空間が設けられ、バンパリインホース１６の軽量化を図ることができる。また、各端部の両内側フランジ２２間を橋渡しするように補強部材２３を備えたことにより、バンパリインホース１６が撓んでも、クラッシュボックス１３の稜線から受ける荷重を補強部材２３で受け、補強部材２３により、バンパリインホース１６への荷重を分散し減少することができる。また、両内側フランジ２２の変形を防止できる。 As described above in detail, according to the present embodiment, the following effects can be obtained.
(1) In the present embodiment, the bumper-in hose 16 is provided with a space between the inner flanges 22 so that the bumper-in hose 16 can be reduced in weight.

In this case, the reinforcing member 23 is coupled to the bumper-in hose 16 by fitting the pair of bent portions 27 to the fitting protrusions 26. Therefore, for example, the fastening means 24 for connecting the bumper inhose 16 and the reinforcing member 23 can be omitted, and the number of parts and the number of manufacturing steps can be reduced.

・前記実施形態において、前記締結手段２４をブラインドナットで構成してもよい。同様に、その他の各部材の締結に係るボルト及び当該ボルトと組み合わされるナットに代えて、ブラインドナットを採用してもよい。この場合、ボルト及びナットの組み合わせのように組み付け方向を二方向にする必要がなく、組み付け方向が一方向のみでよいため、組付け性を向上することができる。   -In the said embodiment, you may comprise the said fastening means 24 with a blind nut. Similarly, a blind nut may be employed instead of a bolt related to fastening of other members and a nut combined with the bolt. In this case, unlike the combination of the bolt and the nut, it is not necessary to set the mounting direction in two directions, and the mounting direction may be only one direction, so that the mounting performance can be improved.
