ところで、特許文献1に開示された車両用フード構造では、補強パネルに開口を設けることで補強パネルを変形しやすくして、フードアウタパネルに外部から衝撃が作用した場合の衝撃吸収性能を確保しているが、更なる衝撃吸収性能の向上が望まれている。そのため、フードインナパネルに開口を形成することが検討されている。
しかし、フードインナパネルに開口を形成する場合、車体側のフードロックからフードストライカを外す操作を行う際に操作者が触れる範囲の開口に対してバリ取り等の処理が必要となり、フード製造工程が煩雑になる。
By the way, in the vehicle hood structure disclosed in Patent Document 1, by providing an opening in the reinforcing panel, the reinforcing panel can be easily deformed, and the shock absorbing performance when an external impact is applied to the hood outer panel is secured. However, further improvement in shock absorbing performance is desired. Therefore, it has been studied to form an opening in the hood inner panel.
However, when forming an opening in the hood inner panel, it is necessary to perform a process such as deburring on the opening that is touched by the operator when removing the hood striker from the hood lock on the vehicle body side. It becomes complicated.

本発明は上記事実を考慮し、衝撃吸収性能を向上させつつ、フード製造工程の煩雑化を抑制できる車両用フード構造を提供することを目的とする。   In view of the above facts, an object of the present invention is to provide a vehicular hood structure capable of suppressing the complication of the hood manufacturing process while improving the impact absorbing performance.

請求項1に記載の車両用フード構造は、車体のフードを構成し、車体の外面を成すアウタパネルと、前記フードを前記車体にロックするためのストライカが車両前方側に取り付けられ、前記フードを構成し、前記アウタパネルよりも車両内側に位置するインナパネルと、前記インナパネルの車両前方側に車両幅方向に間隔をあけて形成された複数の開口と、前記インナパネルに取り付けられ、複数の前記開口のうち前記ストライカの近傍に位置する前記開口を覆うカバー部材と、を備えている。   The hood structure for a vehicle according to claim 1 constitutes a hood of a vehicle body, an outer panel forming an outer surface of the vehicle body, and a striker for locking the hood to the vehicle body is attached to a vehicle front side to constitute the hood.

なお、本実施形態のカバー部材50は、樹脂の一体成型品である   Note that the cover member 50 of the present embodiment is an integrally molded product of resin.

次に、本実施形態のフード構造20の作用効果を説明する。
本実施形態のフード構造20では、インナパネル26の車両前方側に車両幅方向に間隔をあけて複数の開口36を設けていることから、例えば、インナパネルの車両前方側に開口を設けないものと比べて、フード22の車両前方側の剛性が低下し、変形しやすくなる。これにより、フード22を構成するアウタパネル24に外部から衝撃が作用した場合の衝撃吸収性能が向上する。
Next, the effect of the hood structure 20 of this embodiment is demonstrated.
In the hood structure 20 of the present embodiment, since the plurality of openings 36 are provided at intervals in the vehicle width direction on the vehicle front side of the inner panel 26, for example, the openings on the vehicle front side of the inner panel are not provided. As compared with the above, the rigidity of the hood 22 on the front side of the vehicle is reduced and the hood 22 is easily deformed. Thereby, the impact absorption performance when an external impact is applied to the outer panel 24 constituting the hood 22 is improved.

また、インナパネル26に形成された複数の開口36のうち、ストライカ34の近傍に位置する開口36をカバー部材50で覆っている。すなわち、車体側のロック部からストライカ34を外す操作(係合解除操作)を行う際に操作者が触れる範囲の開口36がカバー部材50で覆われている。このため、カバー部材50で覆われる開口36に対してはバリ取り等の処理を省略できるため、フード製造工程の煩雑化を抑制できる。   Of the plurality of openings 36 formed in the inner panel 26, the opening 36 located in the vicinity of the striker 34 is covered with the cover member 50. That is, the cover member 50 covers the opening 36 that is touched by the operator when performing an operation (disengagement operation) for removing the striker 34 from the lock portion on the vehicle body side. For this reason, since the process of deburring etc. can be abbreviate | omitted with respect to the opening 36 covered with the cover member 50, complication of a hood manufacturing process can be suppressed.

また、フード構造20では、カバー部材50のカバー本体52によってパネル部30の開口部38とパネル部32の開口部40が覆われる。このカバー本体52は、開口部38の縁部裏面38Bに係合する係合部56(弾性係合片62)と開口部40の縁部裏面40Bに係合する係合部58(挟持片66)とによって開口36に取り付けられる。すなわち、開口36がインナパネル26を構成する複数のパネル部に亘って形成されていても、カバー本体52(カバー部材50)をインナパネル26の開口36に安定して取り付けることができる。   In the hood structure 20, the cover body 52 of the cover member 50 covers the opening 38 of the panel unit 30 and the opening 40 of the panel unit 32. The cover main body 52 includes an engagement portion 56 (elastic engagement piece 62) that engages with the edge back surface 38B of the opening 38 and an engagement portion 58 (holding piece 66) that engages with the edge back surface 40B of the opening 40. ). That is, even if the opening 36 is formed across a plurality of panel portions constituting the inner panel 26, the cover main body 52 (cover member 50) can be stably attached to the opening 36 of the inner panel 26.

さらに、フード構造20では、カバー部材50をインナパネル26の開口36に取り付ける場合、まず、挟持片66とカバー本体52との間に開口部40の縁部40Aを挟み込み、次に、弾性変形させた状態で弾性係合片62を開口部38に挿入する。そして、挿入された弾性係合片62が復元すると、弾性係合片62の段差部62Aが開口部38の縁部裏面38Bに係合してカバー部材50が開口36に取り付けられる。このように、フード構造20では、カバー部材50を簡単にインナパネル26の開口36に取り付けることができる。   Further, in the hood structure 20, when the cover member 50 is attached to the opening 36 of the inner panel 26, first, the edge 40 </ b> A of the opening 40 is sandwiched between the clamping piece 66 and the cover body 52, and then elastically deformed. In this state, the elastic engagement piece 62 is inserted into the opening 38. When the inserted elastic engagement piece 62 is restored, the stepped portion 62A of the elastic engagement piece 62 is engaged with the edge back surface 38B of the opening 38, and the cover member 50 is attached to the opening 36. Thus, in the hood structure 20, the cover member 50 can be easily attached to the opening 36 of the inner panel 26.

また、フード構造20では、弾性部68及び弾性部70が開口36の縁部表面に当接する場合、弾性部68の弾性力によって弾性係合片62の段差部62Aが開口部38の縁部裏面38Bに押し付けられ(押圧され)、弾性部70の弾性力によって挟持片66が開口部40の縁部裏面40Bに押し付けられる(押圧される)。このため、インナパネル26の開口36の形状に製造上のばらつきがあっても、カバー本体52(カバー部材50)をインナパネル26の開口36に確実に取り付けることができる。   Further, in the hood structure 20, when the elastic portion 68 and the elastic portion 70 come into contact with the edge surface of the opening 36, the stepped portion 62 </ b> A of the elastic engagement piece 62 is caused to be behind the edge portion of the opening 38 by the elastic force of the elastic portion 68. The sandwiching piece 66 is pressed (pressed) against the edge back surface 40B of the opening 40 by the elastic force of the elastic portion 70. For this reason, even if there is a manufacturing variation in the shape of the opening 36 of the inner panel 26, the cover body 52 (cover member 50) can be securely attached to the opening 36 of the inner panel 26.

またさらに、フード構造20では、インナパネル26に形成された開口36が車両前後方向に長尺であっても、係合部56の弾性係合片62が開口部38の延在方向の中央部に位置する縁部裏面38Bに係合し、係合部58が開口部40の延在方向の終端部に位置する縁部裏面40Bに係合することから、カバー本体52(カバー部材50)をインナパネル26の開口36により安定して取り付けることができる。   Furthermore, in the hood structure 20, even if the opening 36 formed in the inner panel 26 is long in the vehicle front-rear direction, the elastic engagement piece 62 of the engagement portion 56 is the central portion in the extending direction of the opening 38. Since the engaging portion 58 engages with the edge back surface 40B located at the terminal end in the extending direction of the opening 40, the cover main body 52 (cover member 50) is engaged. It can be stably attached by the opening 36 of the inner panel 26.

そして、フード構造20では、カバー本体52に操作開口部72を形成していることから、この操作開口部72から係合部56の弾性係合片62の先端部にアクセスして、弾性係合片62の係合状態を解除する操作を例えば、ニッパなどの汎用工具で行うことができる。これにより、インナパネル26の開口36に取り付けたカバー本体52(カバー部材50)を簡単に取り外すことができる。   In the hood structure 20, since the operation opening 72 is formed in the cover body 52, the distal end portion of the elastic engagement piece 62 of the engagement portion 56 is accessed from the operation opening 72 and elastic engagement is performed. The operation of releasing the engagement state of the piece 62 can be performed with a general-purpose tool such as a nipper, for example. Thereby, the cover main body 52 (cover member 50) attached to the opening 36 of the inner panel 26 can be easily removed.

前述の実施形態では、複数の開口36のうちストライカ34の近傍に位置する開口36をカバー部材50で覆う構成としているが、本発明はこの構成に限定されない。ストライカ34の近傍に位置する開口36に加えてその他の開口36もカバー部材50で覆う構成としてもよい。この場合には、さらにバリ取り等の処理を行う開口36の数が減るためフード製造工程の煩雑化がより抑制される。また、すべての開口36をカバー部材50で覆うことでインナパネル26の見栄えの低下を抑制できる。   In the above-described embodiment, the opening 36 positioned in the vicinity of the striker 34 among the plurality of openings 36 is configured to be covered with the cover member 50, but the present invention is not limited to this configuration. In addition to the opening 36 located in the vicinity of the striker 34, the other opening 36 may be covered with the cover member 50. In this case, since the number of openings 36 for further processing such as deburring is reduced, complication of the hood manufacturing process is further suppressed. Further, by covering all the openings 36 with the cover member 50, it is possible to suppress a decrease in the appearance of the inner panel 26.

以上、実施形態を挙げて本発明の実施の形態を説明したが、これらの実施形態は一例であり、要旨を逸脱しない範囲内で種々変更して実施できる。また、本発明の権利範囲がこれらの実施形態に限定されないことは言うまでもない。   The embodiments of the present invention have been described above with reference to the embodiments. However, these embodiments are merely examples, and various modifications can be made without departing from the scope of the invention. It goes without saying that the scope of rights of the present invention is not limited to these embodiments.
