Description

車両用フードのストライカブラケット取付構造Strike bracket mounting structure for vehicle hood
 本発明は、ストライカブラケットをフードインナパネルに取り付ける車両用フードのストライカブラケット取付構造に関する。 The present invention relates to a striker bracket mounting structure for a vehicle hood in which a striker bracket is attached to a hood inner panel.
 フロントフードパネル等の車両用のフードは、エンジンルームを車両上方から覆い、開閉可能に構成されるものである。当該フードは、外板を構成するフードアウタパネルと、内板を構成するフードインナパネルを有する(例えば、特許文献1)。 A vehicle hood such as a front hood panel covers the engine room from above the vehicle and is configured to be openable and closable. The hood has a hood outer panel constituting an outer plate and a hood inner panel constituting an inner plate (for example, Patent Document 1).
フードアウタパネルやフードインナパネルは、通常は、鉄製材料により形成されている。車両の軽量化のために、鉄製材料よりも軽い素材を用いることが求められている。 The hood outer panel and the hood inner panel are usually formed of an iron material. In order to reduce the weight of a vehicle, it is required to use a material that is lighter than an iron material.
特開2008-030574号公報JP 2008-030574 A
 フードインナパネルを、例えば、アルミニウムを含む素材(例えば、アルミニウム合金)で形成する場合には、鉄製の場合の形状をそのまま置き換えるだけでは、当該パネルの機能を確保することができない可能性がある。パネルの各部分への荷重に対する耐久性や変形形態を改善する必要がある。 When the hood inner panel is formed of, for example, a material containing aluminum (for example, an aluminum alloy), the function of the panel may not be ensured by simply replacing the shape in the case of iron. It is necessary to improve the durability against the load on each part of the panel and the deformation mode.
 鉄製パネルよりは剛性が低くまた脆さのあるアルミ製のパネルでフードインナパネルを構成するにためには、基本剛性を得ると共に局所的な応力をより緩和する必要がある。本案の基本構成では、外周閉断面を構成し、フードの車両上方からの荷重吸収のために中央部にビード形状を形成し、さらに、接合をなるべく少なくするために、これらを一体構造にしている。このような複雑な構造を取り入れてパネル剛性を確保しつつ局所応力を緩和したインナパネルについて、フードストライカのような後付け部品からの荷重をもこの構造で吸収分散することが望まれる。 In order to construct a hood inner panel with an aluminum panel that is less rigid than a steel panel and is brittle, it is necessary to obtain basic rigidity and further relax local stress. In the basic configuration of the present plan, an outer peripheral closed cross section is formed, a bead shape is formed in the center portion for absorbing the load from above the vehicle of the hood, and these are integrated in order to minimize joining as much as possible. . With respect to the inner panel in which such a complicated structure is adopted and the local stress is relaxed while ensuring the panel rigidity, it is desired that the load from the retrofitted parts such as the hood striker be absorbed and dispersed by this structure.
 また、フードストライカ近傍では、ストライカがラッチと嵌勘合していて、エネルギ吸収のためのストロークの確保が難しい。歩行者保護頭部の性能を確保するためには、フードアウタパネルとフードインナパネルの間にスペースを設け、その間でストロークを確保するのが一般的である。しかしながら、軽量化の為、フードアウタパネルの板厚を薄くすると、押圧された際の弾性的な凹みにくさが低下してしまうため、フードインナパネルで支持することで、この凹みにくさを確保することとなる。この場合、ストロークを確保することが難しくなり、頭部保護の性能の確保が困難になる。 Also, in the vicinity of the hood striker, the striker is engaged with the latch, so it is difficult to secure a stroke for absorbing energy. In order to ensure the performance of the pedestrian protection head, a space is generally provided between the hood outer panel and the hood inner panel, and a stroke is generally secured between the spaces. However, to reduce the weight, reducing the thickness of the hood outer panel reduces the difficulty of the elastic dent when pressed, so supporting the hood inner panel secures the dent. It will be. In this case, it becomes difficult to secure the stroke, and it becomes difficult to ensure the performance of protecting the head.
 フロントフードパネルは、パネル側のストライカと、車体側のラッチとで、通常は、固定状態にある。フードインナパネルにおいて、フード開閉時の入力により応力集中しやすいストライカブラケットの取付部の荷重分散及び剛性確保が重要となる。すなわち、ストライカを支持するブラケットの取付部では、フロントフードパネルの開閉時の入力では弾性変形範囲での変形による荷重吸収効果を向上させ、上方からの局所入力では、塑性変形での変形による荷重吸収効果を向上させることが重要となる。 The front hood panel is normally fixed with a striker on the panel side and a latch on the vehicle body side. In the hood inner panel, it is important to distribute the load and secure the rigidity of the striker bracket mounting part, where stress is likely to concentrate due to input when the hood is opened and closed. In other words, at the bracket mounting part that supports the striker, the load absorption effect due to deformation in the elastic deformation range is improved when the front hood panel is opened and closed, and the load absorption due to deformation due to plastic deformation is achieved at the local input from above. It is important to improve the effect.

A striker bracket mounting structure for a vehicle hood, comprising: a panel, a striker for opening and closing the vehicle hood, and a striker bracket attached to the hood inner panel and supporting the striker and extending along the vehicle front-rear direction. The outer surface of the hood inner panel is provided with an outer peripheral rib along the outer peripheral edge of the hood inner panel, and an inner rib extending in the vehicle width direction is provided inside the outer peripheral rib. Is formed with a slit extending in the longitudinal direction of the vehicle. Is provided with two rear end portions that are branched on the rear side in the vehicle front-rear direction so as to have a Y shape that opens rearward of the vehicle when viewed from the lower side of the vehicle, and the two rear end portions of the striker bracket include the internal ribs. The front end portion of the striker bracket in the vehicle front-rear direction is connected to the outer peripheral rib of the vehicle front portion.
 また、本発明に係る車両用フードのストライカブラケット取付構造の一態様では、前記ストライカブラケットのY字形状は、車両前後方向で後方部の分岐部と車両前後方向で前方の直線部とで構成され、該直線部は前記スリットと車両下方視で重なり合うように取り付けられている。 Further, in one aspect of the striker bracket mounting structure for a vehicle hood according to the present invention, the Y shape of the striker bracket is constituted by a rear branch portion in the vehicle front-rear direction and a front straight portion in the vehicle front-rear direction. The straight portion is attached so as to overlap with the slit in the vehicle lower view.
 また、本発明に係る車両用フードのストライカブラケット取付構造の一態様では、前記内部リブには、車両後方に向かうに従って車両上方に傾く斜面部が形成され、前記ストライカブラケットの車両後端の接続部は、前記斜面部に接続されている。 Also, in one aspect of the striker bracket mounting structure for a vehicle hood according to the present invention, the internal rib is formed with a slope portion that is inclined upward in the vehicle as it goes toward the rear of the vehicle, and the connecting portion of the striker bracket at the rear end of the vehicle Is connected to the slope portion.
 また、本発明に係る車両用フードのストライカブラケット取付構造の一態様では、前記インナフードパネルには、前記ストライカブラケットの車両前後方向の後端部の前記内部リブに対する接続部に近接する部分に、車両前後方向に延びる補助ビードが設けられ、前記接続部は、前記スリットと前記補助ビードとの間に配置されるように構成されている。 Further, in one aspect of the striker bracket mounting structure for a vehicle hood according to the present invention, the inner hood panel has a portion close to a connection portion with respect to the internal rib at the rear end portion of the striker bracket in the vehicle front-rear direction. An auxiliary bead extending in the vehicle front-rear direction is provided, and the connecting portion is configured to be disposed between the slit and the auxiliary bead.
 また、本発明に係る車両用フードのストライカブラケット取付構造の一態様では、前記スリットは、車幅方向に互いに間隔を空けて複数形成されており、前記複数のスリットは、前記フードインナパネルの車幅方向中心を基準に、幅方向に対称に形成されている。 In one aspect of the striker bracket mounting structure for a vehicle hood according to the present invention, a plurality of the slits are formed at intervals in the vehicle width direction, and the plurality of slits are provided on the vehicle of the hood inner panel. It is formed symmetrically in the width direction with respect to the center in the width direction.
 本発明の一態様によれば、ストライカブラケットの車両前後の端部が内部リブ及び外周リブに接続されるので、結合剛性を確保することができる。また、Y字形状であることで、フード開閉時の入力を、3か所の端部で受けることができ、さらに車両後方では、2箇所の後端部で荷重を受けるので、内部リブにより多くの荷重を分散させることが可能になる。さらに、ストライカブラケットの中央部(中間部)への車両上方からの局所入力に対しては、スリットでフードインナパネルが折れるよう変形させることができる。また、ストライカブラケットはスリットを跨いでいるので、スリットで誘発される折れ変形を阻害しない。 According to one aspect of the present invention, since the front and rear ends of the striker bracket are connected to the internal rib and the outer peripheral rib, the coupling rigidity can be ensured. In addition, because it is Y-shaped, input at the time of opening and closing the hood can be received at three end portions, and further, load is received at the two rear end portions at the rear of the vehicle, so there are more internal ribs. It becomes possible to disperse the load. Furthermore, with respect to local input from above the vehicle to the central portion (intermediate portion) of the striker bracket, the hood inner panel can be deformed so as to be broken by the slit. Moreover, since the striker bracket straddles the slit, it does not hinder the bending deformation induced by the slit.
 また、ストライカブラケットの中央から車幅方向両側(左右)にずれた上方からの局所入力に対しては、ストライカブラケットの分岐部の一方の後方端が入力を受けるので、車両前端の接続部との2点で、倒れるように変形する。ストライカブラケットの倒れに合わせてストライカも倒れることにより、ラッチ固定による上下方向の力(つっぱり)が、車幅方向に逃げるので、変形が大きくなり、荷重吸収のストロークを確保することが可能になる。 For local input from above, shifted from the center of the striker bracket to both sides (left and right) in the vehicle width direction, one rear end of the branching portion of the striker bracket receives input, Deforms to fall down at two points. When the striker is tilted in accordance with the striker bracket, the vertical force (slack) due to the latch fixing escapes in the vehicle width direction, so that the deformation becomes large and a load absorbing stroke can be secured.
 また、本発明の一態様によれば、車両下方視で分岐部がスリット上にあることで、Y字を開く荷重が、分岐部に対して車両前後方向に沿って作用し、スリット及びその周辺が安定した変形をすることが可能となる。 Moreover, according to one aspect of the present invention, when the branch portion is on the slit in the vehicle lower view, the load that opens the Y-shape acts on the branch portion along the vehicle front-rear direction, and the slit and its surroundings. Can be stably deformed.
 また、本発明の一態様によれば、フード開閉時の入力に対しては、内部リブの斜面部に沿って荷重を伝えるので、内部リブの変形が少なく、荷重を接続部の周囲のフードインナパネルに分散させることが可能になる。また、車両上方からの局所入力に対しては、Y字形の分岐部の結合は、内部リブと共に車両後方に移動しながら荷重を吸収するが、内部リブの斜面部にストライカブラケットが沿うように接続されているので、斜面部及びストライカブラケットは、変形途中で分離することや変形方向が別々になることがなく、一緒に移動することが可能となる。 In addition, according to one aspect of the present invention, the load is transmitted along the inclined surface portion of the internal rib when the hood is opened and closed. Therefore, the deformation of the internal rib is small, and the load is transferred to the hood inner around the connection portion. It becomes possible to distribute the panels. In addition, for local input from the top of the vehicle, the connection of the Y-shaped branch part absorbs the load while moving to the rear of the vehicle together with the internal rib, but the striker bracket is connected along the slope of the internal rib. Therefore, the inclined surface portion and the striker bracket can be moved together without being separated in the middle of deformation and in different deformation directions.
 また、本発明の一態様によれば、車両後端の接続部の応力の集中を緩和し、荷重を拡散させることが可能である。フード開閉時および実走行時にストライカブラケットに作用する荷重は、Y字形の分岐部から車両後端に向かい、接続部からフードインナパネルの内部リブに伝わる。近くの形状が変形すると、その変形部分での応力が集中する。本発明のようにビードを設けることで、当該応力の集中を緩和し、荷重を拡散させることが可能である。 Further, according to one aspect of the present invention, it is possible to relax the concentration of stress at the connection portion at the rear end of the vehicle and to spread the load. The load acting on the striker bracket when the hood is opened / closed and during actual traveling is transmitted from the Y-shaped branch portion toward the rear end of the vehicle and is transmitted from the connecting portion to the internal rib of the hood inner panel. When a nearby shape is deformed, stress at the deformed portion is concentrated. By providing a bead as in the present invention, it is possible to reduce the concentration of the stress and diffuse the load.
 また、本発明の一態様によれば、スリット配列を車幅方向に対称化することで、スリットが形成される部分の車両上方からの荷重に対して不利な部分を生じさせないようにすることができ、スリットの変形を阻害しないようにすることが可能である。 Moreover, according to one aspect of the present invention, by symmetrizing the slit arrangement in the vehicle width direction, it is possible to prevent a disadvantageous portion from being generated with respect to the load from above the vehicle in the portion where the slit is formed. It is possible to prevent deformation of the slit.

 図4に示すように、ストライカブラケット21の中間部21fの凸形状の車両上下方向の上部では、車幅方向を折り曲げ線として折れ曲がる折曲部21g,21hが形成される。当該折曲部21g,21hは、通常使用状態では変形しないものの、頭部保護のような大入力時には、変形しやすい形状としている。 As shown in FIG. 4, bent portions 21 g and 21 h that are bent with the vehicle width direction as a fold line are formed in the upper portion of the intermediate portion 21 f of the striker bracket 21 in the vehicle vertical direction. Although the bent portions 21g and 21h are not deformed in a normal use state, the bent portions 21g and 21h have a shape that is easily deformed at the time of a large input such as head protection.
 分岐部21aは、車両下方に凸の中間部21fよりも車両前後方向で後方に設けられる。この例の分岐部21aは、車両下方に凸形状のうち、車両前後方向で後方の折曲部21gと車両前後方向の後端との間に形成されている。 The branch part 21a is provided rearward in the vehicle front-rear direction with respect to the intermediate part 21f protruding downward in the vehicle. The branch portion 21a in this example is formed between the rear bent portion 21g in the vehicle front-rear direction and the rear end in the vehicle front-rear direction of the convex shape below the vehicle.
 ストライカ23は、上述したように車幅方向視でU字状である。ストライカ23の車両前後方向で後側でのストライカブラケット21との結合は、分岐部21aの付近となるように構成されている。 The striker 23 is U-shaped as viewed in the vehicle width direction as described above. The striker 23 is connected to the striker bracket 21 on the rear side in the vehicle longitudinal direction so as to be in the vicinity of the branch portion 21a.
 図3に示すように、ストライカブラケット21の分岐した2つの車両後端部21c,21dは、車両前部の内部リブ40に対して、1個のスリット24の車幅方向両側でそれぞれに接続されている。このときのスリット24は、4つのスリット24のうち、フードインナパネル20の車幅方向中心に近いスリット24である。この例では、車両下方視で右側から2番目のスリット24である。Y字の車両後端部21c,21dのうちの一方で車両下方視の左側の後端部21cは、フードインナパネル20の車幅方向中心付近に接続され
ている。
As shown in FIG. 3, the two branched vehicle rear end portions 21 c and 21 d of the striker bracket 21 are connected to the inner rib 40 of the vehicle front portion on both sides in the vehicle width direction of the single slit 24. ing. The slit 24 at this time is the slit 24 close to the center in the vehicle width direction of the hood inner panel 20 among the four slits 24. In this example, it is the second slit 24 from the right side as viewed from the bottom of the vehicle. One of the Y-shaped vehicle rear end portions 21c and 21d is connected to the rear end portion 21c on the left side of the hood inner panel 20 near the center in the vehicle width direction.
 ストライカブラケット21の車両前後方向の前端部21eは、車両前部の外周リブ30の幅方向延設部33に接続されている。前述したように、当該前端部21eは、幅方向延設部33における平坦部30bに対して車両前後方向で前側の斜面部30aに接続される。ストライカブラケット21の分岐部21aより車両前方の直線部21bは、スリット24の一部と車両下方視で重なり合うように取り付けられている。 The front end portion 21e of the striker bracket 21 in the vehicle front-rear direction is connected to the width direction extending portion 33 of the outer peripheral rib 30 of the vehicle front portion. As described above, the front end portion 21e is connected to the inclined surface portion 30a on the front side in the vehicle front-rear direction with respect to the flat portion 30b in the width direction extending portion 33. The straight portion 21b in front of the vehicle from the branching portion 21a of the striker bracket 21 is attached so as to overlap a part of the slit 24 in the vehicle lower view.
 インナフードパネル20には、補助ビード25が設けられている。この補助ビード25は、インナフードパネル20のうち、ストライカブラケット21の車両前後方向の後端部21c,21dが車両前部の内部リブ40に対して接続する接続部に近接して位置している。この補助ビード25は、車両前後方向に延び、車両下方に突出するように構成される。補助ビード25は、外周リブ30や内部リブ40よりも、突出量等は小さい。ストライカブラケット21の車両前後方向の後端部21c,21dの車両前部の内部リブ40に対する接続部は、車幅方向中心に近いスリット24と補助ビード25との間に配置される。 An auxiliary bead 25 is provided on the inner hood panel 20. The auxiliary bead 25 is located in the inner hood panel 20 in the vicinity of the connection portion where the rear end portions 21c and 21d of the striker bracket 21 in the vehicle front-rear direction are connected to the internal rib 40 at the front portion of the vehicle. . The auxiliary bead 25 is configured to extend in the vehicle front-rear direction and protrude downward in the vehicle. The auxiliary bead 25 has a smaller amount of protrusion than the outer peripheral rib 30 and the inner rib 40. The connecting portions of the rear end portions 21c, 21d of the striker bracket 21 with respect to the inner rib 40 at the front portion of the vehicle are arranged between the slit 24 and the auxiliary bead 25 near the center in the vehicle width direction.
 以上の説明からわかるように本実施形態によれば、ストライカブラケット21は、車両前後方向の前側の端部が外周リブ30に接続され、車両前後方向の後側の端部が内部リブ40に接続されるので、結合剛性を確保することができる。また、ストライカブラケット21は、Y字形状であることで、フード開閉時の入力を、3か所の端部で受けることができ、さらに車両前後方向の後方では、2箇所の後端部21c,21dで荷重を受けるので、内部リブ40により多くの荷重を分散させることが可能になる。さらに、ストライカブラケット21の中央部(中間部21f)への車両上方からの局所入力に対しては、車幅方向中心に近いスリット24でフードインナパネル20が折れるよう変形させることができる。また、ストライカブラケット21はスリット24を跨いでいるので、車幅方向中心に近いスリット24で誘発される折れ変形を阻害しない。 As can be seen from the above description, according to the present embodiment, the striker bracket 21 has the front end in the vehicle front-rear direction connected to the outer peripheral rib 30 and the rear end in the vehicle front-rear direction connected to the inner rib 40. Therefore, the coupling rigidity can be ensured. Further, since the striker bracket 21 is Y-shaped, it can receive an input at the time of opening and closing the hood at three end portions, and further, two rear end portions 21c, Since the load is received at 21d, a large amount of load can be distributed to the internal rib 40. Furthermore, with respect to local input from above the vehicle to the central portion (intermediate portion 21f) of the striker bracket 21, the hood inner panel 20 can be deformed so as to be broken by the slit 24 near the center in the vehicle width direction. Further, since the striker bracket 21 straddles the slit 24, it does not hinder the bending deformation induced by the slit 24 near the center in the vehicle width direction.
 また、ストライカブラケット21の中央から車幅方向両側(左右)にずれた上方からの局所入力に対しては、ストライカブラケット21の分岐部21aの一方の後方端が入力を受ける。このため、当該一方の後端部(21c及び21dのうちの一方)の接続部と車両前端部21eの接続部との2点で、倒れるように変形する。ストライカブラケット21の倒れに合わせてストライカ23も倒れるので、ラッチ固定による上下方向の力(つっぱり)が、車幅方向に逃げるので、変形が大きくなり、荷重吸収のストロークを確保することが可能になる。 Also, with respect to local input from above shifted from the center of the striker bracket 21 to both sides (left and right) in the vehicle width direction, one rear end of the branch portion 21a of the striker bracket 21 receives input. For this reason, it deform | transforms so that it may fall down at two points, the connection part of the said one rear end part (one of 21c and 21d) and the connection part of the vehicle front end part 21e. As the striker bracket 21 is tilted, the striker 23 is also tilted, so that the vertical force (slack) due to the latch fixing escapes in the vehicle width direction, so that deformation becomes large and it is possible to secure a load absorption stroke. .
 また、本実施形態によれば、車両下方視で分岐部21aがスリット24上にあることで、Y字を開く荷重が、分岐部21aに対して車両前後方向に沿って作用し、スリット24及びその周辺が安定した変形をすることが可能となる。 Further, according to the present embodiment, since the branch portion 21a is on the slit 24 when viewed from the lower side of the vehicle, the load that opens the Y-shape acts on the branch portion 21a along the vehicle front-rear direction. The surroundings can be stably deformed.
 さらに、フード開閉時の入力に対しては、内部リブ40の斜面部40aに沿って荷重を伝えるので、内部リブ40の変形が少なく、荷重を接続部の周囲のフードインナパネル20に分散させることが可能になる。また、車両上方からの局所入力に対しては、Y字形の分岐部21aの結合は、内部リブ40と共に車両後方に移動しながら荷重を吸収するが、内部リブ40の斜面部40aにストライカブラケット21が沿うように接続されているので、斜面部40a及びストライカブラケット21は、変形途中で分離することや変形方向が別々になることがなく、一緒に移動することが可能となる。 Further, since the load is transmitted along the inclined surface portion 40a of the internal rib 40 for the input at the time of opening and closing the hood, the deformation of the internal rib 40 is small and the load is distributed to the hood inner panel 20 around the connection portion. Is possible. For local input from above the vehicle, the connection of the Y-shaped branching portion 21a absorbs the load while moving to the rear of the vehicle together with the internal rib 40, but the striker bracket 21 is attached to the inclined surface portion 40a of the internal rib 40. Therefore, the inclined surface portion 40a and the striker bracket 21 can be moved together without being separated in the middle of deformation and in different deformation directions.
 しかも、車両後端部21c,21dの接続部の応力の集中を緩和し、荷重を拡散させることが可能である。フード開閉時および実走行時にストライカブラケット21に作用する荷重は、Y字形の分岐部21aから車両後端部21c,21dに向かい、接続部からフードインナパネル20の内部リブ40に伝わる。近くの形状が変形すると、その変形部分での応力が集中する。本実施形態のように補助ビード25を設けることで、当該応力の集中を緩和し、荷重を拡散させることが可能である。 Moreover, it is possible to alleviate the concentration of stress at the connecting portions of the rear end portions 21c and 21d of the vehicle and to spread the load. The load acting on the striker bracket 21 when the hood is opened / closed and during actual traveling is transmitted from the Y-shaped branch portion 21a toward the vehicle rear end portions 21c and 21d and from the connection portion to the internal rib 40 of the hood inner panel 20. When a nearby shape is deformed, stress at the deformed portion is concentrated. By providing the auxiliary bead 25 as in the present embodiment, it is possible to alleviate the stress concentration and diffuse the load.
 また、各スリット24の縁部に車両下方に突出するリブ形状を設けているので、スリット24の角部に応力が集中することを抑制することができる。また、当該リブ形状を設け
ることで、当該縁部が塑性変形しにくくなる。
Moreover, since the rib shape which protrudes below a vehicle is provided in the edge part of each slit 24, it can suppress that stress concentrates on the corner | angular part of the slit 24. FIG. Further, by providing the rib shape, the edge portion is difficult to be plastically deformed.
 また、スリット24の配列を車幅方向に対称化することで、スリット24が形成される部分の車両上方からの荷重に対して不利な部分を生じさせないようにすることができ、ス
リット24の変形を阻害しないようにすることが可能である。
Further, by making the arrangement of the slits 24 symmetric in the vehicle width direction, it is possible to prevent a disadvantageous portion from being generated with respect to the load from above the vehicle in the portion where the slits 24 are formed. It is possible not to inhibit.
