Description

本発明は、自動車のトランクルーム内にスペアタイヤを固定するためのスペアタイヤ固定ベースに関するものである。   The present invention relates to a spare tire fixing base for fixing a spare tire in a trunk room of an automobile.

自動車のトランクルーム内にスペアタイヤを固定する手段として、カップを伏せた形状に鋼板をプレス成形してなるブラケットをスペアタイヤ格納部の底面に溶接付けし、ブラケットの上部に固着したナット部材に上方からボルト部材を螺着してスペアタイヤを止め付けるようにした構造が知られている（特許文献１を参照されたい）。このブラケットは、その基端に形成されたフランジを、スペアタイヤ格納部の底壁上面にスポット溶接などで結合することが一般的である。
実開平７−２１４８６号公報 As a means to fix the spare tire in the trunk room of an automobile, a bracket formed by pressing a steel plate in a cup-down shape is welded to the bottom surface of the spare tire storage part, and the nut member fixed to the upper part of the bracket is viewed from above. A structure in which a spare tire is fastened by screwing a bolt member is known (see Patent Document 1). In general, the bracket has a flange formed at the base end thereof coupled to the upper surface of the bottom wall of the spare tire storage portion by spot welding or the like.
Japanese Utility Model Publication No. 7-21486

特許文献１に記載の技術によると、スポット溶接による接着強度が不十分であると、例えば正面衝突時にブラケットに過剰な力が加わった際に、スペアタイヤ格納部の底壁からブラケットが剥離してスペアタイヤが前方へ移動することが考えられる。   According to the technique described in Patent Document 1, if the adhesive strength by spot welding is insufficient, for example, when an excessive force is applied to the bracket during a frontal collision, the bracket peels off from the bottom wall of the spare tire storage unit. It is conceivable that the spare tire moves forward.

本発明は、このような従来技術の不都合を解消すべく案出されたものであり、その主な目的は、大きな力が加わった際の剥離強度をより一層高めることのできるスペアタイヤ固定ベースを提供することにある。   The present invention has been devised to eliminate such disadvantages of the prior art, and its main purpose is to provide a spare tire fixing base that can further increase the peel strength when a large force is applied. It is to provide.

このような課題を解決するために本発明は、上向きに凸形状をなすアンカブラケット４の基端に設けられたフランジ３を、フロアパネルに形成されたスペアタイヤ格納部の底壁２に固定してなるスペアタイヤ固定ベース１において、中央部に凹み５を形成したアンカプレート６を備え、アンカプレートの凹み内にフランジを溶接し、スペアタイヤ格納部の底壁に設けられた孔７にアンカブラケットの凸形状をなす部分を下方から挿入し、アンカプレートと孔の周囲との間にフランジを挟み込んだ態様でアンカプレートの外周側部分をスペアタイヤ格納部の底壁に溶接するものとした。   In order to solve such a problem, the present invention fixes a flange 3 provided at a base end of an upwardly protruding anchor bracket 4 to a bottom wall 2 of a spare tire storage portion formed on a floor panel. The spare tire fixing base 1 is provided with an anchor plate 6 having a recess 5 formed in the center, a flange is welded in the recess of the anchor plate, and an anchor bracket is inserted into a hole 7 provided in the bottom wall of the spare tire storage portion. The portion having the convex shape is inserted from below, and the outer peripheral side portion of the anchor plate is welded to the bottom wall of the spare tire storage portion in such a manner that the flange is sandwiched between the anchor plate and the periphery of the hole.

このような本発明によれば、アンカブラケットのフランジがスペアタイヤ格納部の底壁とアンカプレートとで挟み込まれるので、アンカブラケットに大きな荷重が加わっても、アンカブラケットのフランジがスペアタイヤ格納部の底壁から剥離し難くなる。即ち、車両衝突時にスペアタイヤが前方へ移動する虞を払拭する上に効果的である。また本発明の構造によると、フランジの厚さや材質の設定で高い抜け強度を容易に確保することができるので、スポット溶接強度に依存する従来の構造に比して、製品強度を確保する上での工程管理を簡略化することができる。   According to the present invention as described above, the flange of the anchor bracket is sandwiched between the bottom wall of the spare tire storage portion and the anchor plate. Therefore, even if a large load is applied to the anchor bracket, the flange of the anchor bracket is not attached to the spare tire storage portion. It becomes difficult to peel off from the bottom wall. That is, it is effective in wiping out the possibility that the spare tire moves forward in the event of a vehicle collision. In addition, according to the structure of the present invention, it is possible to easily ensure a high pull-out strength by setting the thickness and material of the flange, so that it is possible to secure the product strength as compared with the conventional structure depending on the spot welding strength. The process management can be simplified.

以下に添付の図面を参照して本発明について詳細に説明する。   Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

図１・２は、本発明に基づき構成されたスペアタイヤの固定ベースを示している。この固定ベース１は、図３に示すように、鋼板でプレス成形されたリアフロアパネルＦＰに一体形成されたスペアタイヤ格納部の底壁２に固着されており、径方向外向きの大略扇形をなす一対のフランジ３が基端に設けられ、且つカップを伏せた様な上向きの凸形状をなすアンカブラケット４と、アンカブラケット４のフランジ３の厚さに相当する凹み５がその中央部に形成された概ね長円形の皿状をなすアンカプレート６とからなっている。   1 and 2 show a fixed base for a spare tire constructed according to the present invention. As shown in FIG. 3, the fixed base 1 is fixed to a bottom wall 2 of a spare tire storage unit integrally formed with a rear floor panel FP press-formed with a steel plate, and forms a generally fan shape radially outward. A pair of flanges 3 are provided at the base end, and an anchor bracket 4 having an upward convex shape such that the cup is depressed, and a recess 5 corresponding to the thickness of the flange 3 of the anchor bracket 4 are formed at the center thereof. It consists of an anchor plate 6 having a generally oval dish shape.

この固定ベース１は、アンカブラケット４のフランジ３をアンカプレート６の凹み５に載せた状態で、フランジ３とアンカプレート６とがスポット溶接にて一体結合されており、スペアタイヤ格納部の底壁２に設けられた孔７にアンカブラケット４の凸形状をなす部分を下方から挿入し、且つスペアタイヤ格納部の底壁２の下面にアンカプレート６の外周側部分を溶接付けすることにより、スペアタイヤ格納部の底壁２の下面とアンカプレート６の凹み５との間にフランジ３を挟み込んだ態様にて、スペアタイヤ格納部の底壁２に一体的に結合されている。   The fixed base 1 has the flange 3 and the anchor plate 6 integrally joined by spot welding in a state in which the flange 3 of the anchor bracket 4 is placed on the recess 5 of the anchor plate 6. By inserting the convex portion of the anchor bracket 4 into the hole 7 provided in the bottom 2 and welding the outer peripheral portion of the anchor plate 6 to the lower surface of the bottom wall 2 of the spare tire storage portion, The flange 3 is sandwiched between the lower surface of the bottom wall 2 of the tire storage portion and the recess 5 of the anchor plate 6 and is integrally coupled to the bottom wall 2 of the spare tire storage portion.

アンカプレート６に形成された凹み５の中央部には、フランジ３の載置面から更に深くされた窪み８が形成されており、その底面には、ゴム材のキャップ９で閉じられるドレン孔１０が開けられている。   At the center of the recess 5 formed in the anchor plate 6 is formed a recess 8 that is further deepened from the mounting surface of the flange 3, and a drain hole 10 that is closed by a rubber cap 9 on its bottom surface. Is opened.

なお、スペアタイヤ格納部の底壁２の下面とアンカプレート６の外周側部分との間にはシーラント材（図示せず）が予め塗布されており、孔７からの浸水を防止している。   A sealant material (not shown) is applied in advance between the lower surface of the bottom wall 2 of the spare tire storage portion and the outer peripheral side portion of the anchor plate 6 to prevent water from entering through the holes 7.

アンカブラケット４のトランクルーム内に突出した凸形状をなす部分の頂部下面には、ナット部材１１が溶接されており、スペアタイヤ（図示せず）を載置した上でホイールのセンタ孔あるいはクリップボルト孔を介して固定ボルトをナット部材１１に螺着することにより、スペアタイヤが固定ベース１に固定されるようになっている。なお、固定ベース１にスペアタイヤをボルト止めすることは、特許文献１に記載されている通り周知のことなので、ここではこれ以上の説明は省略する。   A nut member 11 is welded to the bottom surface of the convex portion protruding into the trunk room of the anchor bracket 4, and a spare tire (not shown) is placed on the center hole or clip bolt hole of the wheel. The spare tire is fixed to the fixed base 1 by screwing the fixing bolt to the nut member 11 via the screw. In addition, since it is known that the spare tire is bolted to the fixed base 1 as described in Patent Document 1, further explanation is omitted here.

このように構成されたスペアタイヤの固定ベース１によれば、例えば前面衝突などでスペアタイヤの慣性による大きな荷重がアンカブラケット４に加わった際にも、スペアタイヤ格納部の底壁２及び底壁２の下面に接合されたアンカプレート６がアンカブラケット４に加わる荷重を受け止めることとなる。このため、スペアタイヤ格納部の底壁２からアンカブラケット４が脱落することが防止され、スペアタイヤの拘束力が失われずに済むことから、スペアタイヤが前方へ移動して荷室と車室間に設けられた機器に損傷を与えたり、後部座席のシートバックにスペアタイヤが突き当たったりする心配がなくなる。   According to the fixed base 1 of the spare tire configured in this way, even when a large load due to inertia of the spare tire is applied to the anchor bracket 4 due to, for example, a frontal collision, the bottom wall 2 and the bottom wall of the spare tire storage portion The anchor plate 6 joined to the lower surface of 2 receives the load applied to the anchor bracket 4. For this reason, the anchor bracket 4 is prevented from dropping off from the bottom wall 2 of the spare tire storage section, and the binding force of the spare tire is not lost, so that the spare tire moves forward and the space between the luggage compartment and the compartment. There is no need to worry about damaging the equipment installed on the seat or having the spare tire hit the seat back of the rear seat.
