従来、乗員が乗車するキャブ後方に箱型の車両荷箱を備える車両がある。この種の車両においては、車両荷箱の補強を図る技術が開示されている。例えば、特許文献1には、荷台の側壁の前縁に沿って該荷台の床よりも下方にまで延びて該側壁が結合されるデッキフロントピラーと、デッキフロントピラーのうち荷台の床よりも上側でキャビンと結合する上側結合部と、デッキフロントピラーのうち荷台の床よりも下側でキャビンと結合する下側結合部と、を備える車両用荷台結合構造が開示されている。
Conventionally, there are vehicles that are equipped with a box-shaped vehicle cargo box behind the cab where passengers ride. In this type of vehicle, techniques for reinforcing the vehicle cargo box have been disclosed. For example, Patent Document 1 describes a deck front pillar that extends below the floor of the loading platform along the front edge of the side wall of the loading platform and is connected to the side wall, and a deck front pillar that extends below the floor of the loading platform along the front edge of the loading platform, and A vehicle cargo bed coupling structure is disclosed that includes an upper coupling portion that couples to the cabin at a portion of the deck front pillar and a lower coupling portion that couples to the cabin at a portion of the deck front pillar below the floor of the cargo platform.
特許文献1に開示された技術においては、荷台の床に交差して上下に延びるデッキフロントピラーを利用して、荷台の側壁のキャビンへの結合剛性を向上させる、というものである。このように剛性向上のための結合部が上側及び下側の両方に設けられた構成では、重量が増大してしまう問題があった。
The technology disclosed in Patent Document 1 uses a deck front pillar that extends vertically across the floor of the cargo platform to improve the rigidity of the side wall of the cargo platform to the cabin. In such a configuration in which the joint portions for improving rigidity are provided on both the upper and lower sides, there is a problem in that the weight increases.
本発明はこのような課題に鑑みてなされたものであり、その目的とするところは、重量の増大が回避でき且つ効果的な補強が可能な車両荷箱構造を提供することにある。
The present invention has been made in view of these problems, and its purpose is to provide a vehicle cargo box structure that can avoid an increase in weight and can be effectively reinforced.

図1及び図2は、本発明の車両荷箱の補強構造が適用され得る、車両荷箱1の斜視図である。図1及び図2の車両荷箱1は、細部が異なるが、概要は同様の構成であるので同一の符号を付す。
1 and 2 are perspective views of a vehicle cargo box 1 to which the vehicle cargo box reinforcing structure of the present invention can be applied. Although the vehicle cargo boxes 1 in FIGS. 1 and 2 differ in detail, they have the same general configuration and are therefore given the same reference numerals.
車両荷箱1は、車両のキャビン後方に配置される。車両荷箱1は、前方のヘッダーボード2と、左右の一対のサイドゲート3,3と、後方のテールゲート4と、下方のフロアパネル5と、を有する。
The vehicle cargo box 1 is placed behind the cabin of the vehicle. The vehicle cargo box 1 includes a front header board 2, a pair of left and right side gates 3, 3, a rear tailgate 4, and a lower floor panel 5.
ヘッダーボード2は、車両荷箱1における前方側の壁面を構成し、左右方向(車幅方向)に延びる。
一対のサイドゲート3,3は、ヘッダーボード2に交差して配置される。具体的には、一対のサイドゲート3,3は、ヘッダーボード2の左右両端部に接続され、主に車両後方に延びて、車両荷箱1の左右両側の壁面を構成する。それぞれのサイドゲート3の下端部には、ホイールアーチ3aが形成される。
テールゲート4は、一対のサイドゲート3,3の後方端部に接続され、左右方向に延びる。
フロアパネル5は、ヘッダーボード2と、一対のサイドゲート3,3と、テールゲート4と、で囲まれた空間の下方側を閉じる。 Theheader board 2 constitutes the front wall surface of the vehicle cargo box 1 and extends in the left-right direction (vehicle width direction).
A pair of side gates 3, 3 are arranged across the header board 2. Specifically, the pair of side gates 3, 3 are connected to both left and right ends of the header board 2, extend mainly toward the rear of the vehicle, and constitute the left and right wall surfaces of the vehicle cargo box 1. A wheel arch 3a is formed at the lower end of each side gate 3.
Thetailgate 4 is connected to the rear end portions of the pair of side gates 3, 3, and extends in the left-right direction.
Thefloor panel 5 closes the lower side of the space surrounded by the header board 2, the pair of side gates 3, and the tail gate 4.
一対のサイドゲート3,3は、ヘッダーボード2に交差して配置される。具体的には、一対のサイドゲート3,3は、ヘッダーボード2の左右両端部に接続され、主に車両後方に延びて、車両荷箱1の左右両側の壁面を構成する。それぞれのサイドゲート3の下端部には、ホイールアーチ3aが形成される。
テールゲート4は、一対のサイドゲート3,3の後方端部に接続され、左右方向に延びる。
フロアパネル5は、ヘッダーボード2と、一対のサイドゲート3,3と、テールゲート4と、で囲まれた空間の下方側を閉じる。 The

このように、車両荷箱1は、ヘッダーボード2と、一対のサイドゲート3,3と、テールゲート4と、フロアパネル5と、によって構成された上面視矩形状の収容空間である。
As described above, the vehicle cargo box 1 is a rectangular storage space when viewed from above, which is configured by the header board 2, the pair of side gates 3, 3, the tail gate 4, and the floor panel 5.
ヘッダーボード2の上部には、車幅方向に沿ってアッパーレール30が溶接等によって固定される。図1の例では、アッパーレール30の上部に、ガードフレーム60が固定される。
An upper rail 30 is fixed to the top of the header board 2 along the vehicle width direction by welding or the like. In the example of FIG. 1, a guard frame 60 is fixed to the upper part of the upper rail 30.
ヘッダーボード2、一対のサイドゲート3、及びテールゲート4は、フロアパネル5に立脚するように取り付けられている。なお、テールゲート4の下端部は、フロアパネル5に対して図1のように回動可能に設けられており、荷物を車両荷箱1に出し入れし易いように構成されている。
The header board 2, the pair of side gates 3, and the tailgate 4 are attached to stand on the floor panel 5. The lower end of the tailgate 4 is rotatably provided with respect to the floor panel 5 as shown in FIG. 1, and is configured to facilitate loading and unloading of luggage into the vehicle cargo box 1.
図2に示すように、テールゲート4が閉じられた状態で、車両荷箱1内に多くの荷物を積んだ場合、ヘッダーボード2、サイドゲート3、及びテールゲート4には、荷箱内側から荷箱外側に向うような外向きの力F1(車両荷箱1の中央から4辺に対して略直角に外側に向く力を想定)が加わる。この外向きの力F1によって、ヘッダーボード2の車幅方向両端部と、一対のサイドゲート3,3の車幅方向内側面と、の連結部分には、当該連結部分を開くように荷重が負荷される。
As shown in FIG. 2, when the tailgate 4 is closed and a large amount of cargo is loaded into the vehicle cargo box 1, the header board 2, side gate 3, and tailgate 4 are loaded from inside the cargo box. An outward force F1 directed toward the outside of the cargo box (assuming a force directed outward from the center of the vehicle cargo box 1 at a substantially right angle to the four sides) is applied. Due to this outward force F1, a load is applied to the connecting portion between both ends of the header board 2 in the vehicle width direction and the inner surfaces in the vehicle width direction of the pair of side gates 3, 3 to open the connecting portion. be done.
また、例えば、一対のサイドゲート3,3間にロープを掛けて車幅方向に結束したり、またはヘッダーボード2とテールゲート4間にロープを掛けて前後方向に結束した場合には、荷箱外側から荷箱内側に向うような内向きの力F2が加わる。この内向きの力F2によって、ヘッダーボード2の車幅方向両端部と、一対のサイドゲート3,3の車幅方向内側面と、の連結部分には、当該連結部分を閉じるように荷重が負荷される。
In addition, for example, if a rope is hung between a pair of side gates 3 and 3 to bind them in the vehicle width direction, or a rope is hung between the header board 2 and tailgate 4 to bind them in the longitudinal direction, the cargo box An inward force F2 is applied from the outside toward the inside of the cargo box. Due to this inward force F2, a load is applied to the connecting portion between both ends of the header board 2 in the vehicle width direction and the inner surfaces in the vehicle width direction of the pair of side gates 3, 3 so as to close the connecting portion. be done.
このように、ヘッダーボード2と一対のサイドゲート3,3との連結部分には、荷重が負荷されやすく、特に当該連結部分のうち上端部が弱部となりやすい。そこで、本実施形態の車両荷箱1においては、ヘッダーボード2と一対のサイドゲート3,3とが、これらとは別体の板状のブラケット10(固定部材)によって連結されて補強される。より具体的には、ヘッダーボード2の車幅方向両端部の上端部と一対のサイドゲート3,3とは、後述するブラケット10(図3~図8参照)を含む連結固定部分A,Aを介して連結されて補強されている。なお、図1及び図2にはブラケット10は不図示である。
As described above, a load is easily applied to the connecting portion between the header board 2 and the pair of side gates 3, and the upper end of the connecting portion is particularly likely to become a weak portion. Therefore, in the vehicle cargo box 1 of this embodiment, the header board 2 and the pair of side gates 3, 3 are connected and reinforced by a separate plate-shaped bracket 10 (fixing member). More specifically, the upper end portions of both ends in the vehicle width direction of the header board 2 and the pair of side gates 3 have connecting fixed portions A, A including a bracket 10 (see FIGS. 3 to 8), which will be described later. They are connected and reinforced through. Note that the bracket 10 is not shown in FIGS. 1 and 2.
図3は、ヘッダーボード2とサイドゲート3との連結固定部分Aの周辺を示す斜視図である。図4は、図3の要部拡大図である。図5は、ヘッダーボード2とサイドゲート3との連結固定部分Aの周辺を、ヘッダーボード2を省略して示す斜視図である。図6は、ヘッダーボード2とサイドゲート3との連結固定部分Aの周辺を示す上面図である。図7は、図6の要部拡大図である。図8は、ヘッダーボード2とサイドゲート3との連結固定部分Aの周辺を後方から見た図である。
FIG. 3 is a perspective view showing the vicinity of the connecting and fixing portion A between the header board 2 and the side gate 3. FIG. 4 is an enlarged view of the main part of FIG. 3. FIG. 5 is a perspective view showing the periphery of a connecting and fixed portion A between the header board 2 and the side gate 3, with the header board 2 omitted. FIG. 6 is a top view showing the vicinity of the connecting and fixing portion A between the header board 2 and the side gate 3. As shown in FIG. FIG. 7 is an enlarged view of the main part of FIG. FIG. 8 is a view of the periphery of the connecting and fixing portion A between the header board 2 and the side gate 3, seen from the rear.
ヘッダーボード2と一対のサイドゲート3,3との左右の連結固定部分A,Aは、車幅方向において対称である。したがって、以下の説明では、右側の連結固定部分Aのみを図示して説明する。
The left and right connecting and fixing parts A, A between the header board 2 and the pair of side gates 3, 3 are symmetrical in the vehicle width direction. Therefore, in the following description, only the right side connecting and fixing portion A will be illustrated and explained.
図3~図8に示すように、連結固定部分Aにおいては、ヘッダーボード2とサイドゲート3とを連結する板状の固定部材としてのブラケット10が設けられている。ブラケット10の詳細については、後述する。
As shown in FIGS. 3 to 8, in the connecting and fixing portion A, a bracket 10 is provided as a plate-shaped fixing member that connects the header board 2 and the side gate 3. Details of the bracket 10 will be described later.
ヘッダーボード2の上端部2a(上部)には、横断面形状が屈曲形状をなす第1補強部材としてのアッパーレール30が、車幅方向に沿って設けられる。アッパーレール30は、ヘッダーボード2に溶接等によって固定される。アッパーレール30は、ヘッダーボード2の前面に沿うように上下方向に延びる基部30aと、基部30aの上端部から前方に延びる延在部30bと、を備える。延在部30bの前端部は下方及び後方に屈曲したフック形状とされており、車両荷箱1に載置した荷物を固定するためのロープ等を固定可能である。このように、アッパーレール30は、概ね断面逆L字形状とされている。第1補強部材としてのアッパーレール30が設けられることで、アッパーレールがヘッダーボード2の上端部2aが補強される。
An upper rail 30 serving as a first reinforcing member having a bent cross-sectional shape is provided at the upper end 2a (upper part) of the header board 2 along the vehicle width direction. The upper rail 30 is fixed to the header board 2 by welding or the like. The upper rail 30 includes a base portion 30a that extends in the vertical direction along the front surface of the header board 2, and an extension portion 30b that extends forward from the upper end of the base portion 30a. The front end portion of the extension portion 30b has a hook shape bent downward and backward, and a rope or the like for securing cargo placed in the vehicle cargo box 1 can be fixed thereto. In this way, the upper rail 30 has a generally inverted L-shaped cross section. By providing the upper rail 30 as the first reinforcing member, the upper end portion 2a of the header board 2 is reinforced by the upper rail.
また、サイドゲート3は、全体として車幅方向外側に膨出するように湾曲しており、ヘッダーボード2よりも車両前方に位置する前側部分3bと、ヘッダーボード2よりも車両後方に位置する後側部分3cと、を有する。サイドゲート3の所定箇所としての前側部分3bの車幅方向内側面には、第2補強部材としての前側リンフォース40が固定される。また、サイドゲート3には、ヘッダーボード2よりも車両後方に、第3補強部材としての後側リンフォース50が固定される。
The side gate 3 as a whole is curved so as to bulge outward in the vehicle width direction, and has a front portion 3b located in front of the vehicle than the header board 2, and a rear portion 3b located in the rear of the vehicle than the header board 2. and a side portion 3c.

A through hole 11a extending in the vertical direction is formed approximately at the center of the first fixed portion 11. The upper surface of the first fixed portion 11 abuts on the upper surface of the header board 2, more specifically, on the lower surface of the extending portion 30b of the upper rail 30. The first fixed portion 11 is fixed to the lower surface of the extending portion 30b of the upper rail 30 through the through hole 11a by welding or the like.

In the installed state, the second fixed portion 12 is located at the lower end side of the bracket 10 and extends substantially perpendicular to the vehicle width direction (substantially parallel to the vertical direction and the front-rear direction). Strictly speaking, the illustrated second fixed portion 12 is slightly inclined outward in the vehicle width direction toward the bottom, thereby enhancing the stress dispersion effect. A through hole 12a extending in the vehicle width direction is formed approximately at the center of the second fixed portion 12.

したがって、接続部13の下端と接続する第2固定部分12は、全体として、第1固定部分11よりも前方に膨出する。これにより、第2固定部分12の略中央に設けられた貫通孔12a及び貫通孔12aが構成する第2固定点P2は、第1固定部分11の略中央に設けられた貫通孔11a及び貫通孔11aが構成する第1固定点P1よりも下方且つ前方に位置する。すなわち、図11に示すように、第1固定点P1と、第2固定点P2とは、前後方向に距離L1だけオフセットし、上下方向に距離L2だけオフセットする。
Therefore, the second fixed portion 12 that connects to the lower end of the connecting portion 13 bulges out further forward than the first fixed portion 11 as a whole. As a result, the second fixing point P2 formed by the through hole 12a provided approximately at the center of the second fixed portion 12 and the second fixing point P2 formed by the through hole 12a provided approximately at the center of the first fixed portion 11 is 11a is located below and in front of the first fixed point P1. That is, as shown in FIG. 11, the first fixed point P1 and the second fixed point P2 are offset by a distance L1 in the front-back direction and by a distance L2 in the vertical direction.

したがって、第2接続部15には、中央に側面視略矩形の第2傾斜部22が配置され、第2傾斜部22の周囲に側面視略台形の第1,3,4,5傾斜部21,23,24,25が配置される。そして、第1~第5傾斜部21~25のうち中央の第2傾斜部22が、ブラケット10の厚み方向(車幅方向外側)に最も突出した形状となる。このように、接続部13に複数の稜線71~78からなる屈曲構造が設けられているので、ブラケット10の剛性を高めることができる。
Therefore, in the second connecting portion 15, a second inclined portion 22 having a substantially rectangular shape in side view is arranged at the center, and first, third, fourth, and fifth inclined portions 21 having a substantially trapezoidal shape in side view are arranged around the second inclined portion 22. , 23, 24, and 25 are arranged. Of the first to fifth inclined parts 21 to 25, the second inclined part 22 at the center has a shape that projects most in the thickness direction (outside in the vehicle width direction) of the bracket 10. In this way, since the connecting portion 13 is provided with the bending structure consisting of the plurality of ridge lines 71 to 78, the rigidity of the bracket 10 can be increased.
ここで、図2を参照して上述したように、車両荷箱1内に多くの荷物を積んだ場合、ヘッダーボード2、一対のサイドゲート3,3及びテールゲート4には、荷箱内側から荷箱外側に向かう外向きの力F1が加わる。この外向きの力F1によって、ヘッダーボード2は車両前方に向かって押され、サイドゲート3は車幅方向外側に押される。この場合、ヘッダーボード2の車幅方向両端部と、一対のサイドゲート3,3の車幅方向内側面と、の連結部分には、当該連結部分を開くような力が加わる。
Here, as described above with reference to FIG. 2, when a large amount of cargo is loaded in the vehicle cargo box 1, the header board 2, the pair of side gates 3, 3, and the tailgate 4 are loaded from the inside of the cargo box. An outward force F1 directed toward the outside of the cargo box is applied. This outward force F1 pushes the header board 2 toward the front of the vehicle and pushes the side gate 3 outward in the vehicle width direction. In this case, a force is applied to the connecting portion between both ends of the header board 2 in the vehicle width direction and the inner surfaces of the pair of side gates 3 in the vehicle width direction to open the connecting portion.
同様に図2を参照して上述したように、ヘッダーボード2とテールゲート4間にロープを掛けて前後方向に結束した場合には、荷箱外側から荷箱内側に向うような内向きの力F2が加わる。この内向きの力F2によって、ヘッダーボード2の車幅方向両端部と、一対のサイドゲート3,3の車幅方向内側面と、の連結部分には、当該連結部分を閉じるような力が加わる。図13は、連結固定部分Aを車幅方向から見て、一部破断して示す側面図である。上述のような内向きの力F2が加わる際には、図13に矢印で示すように、特にロープのフック等が掛けられるアッパーレール30の延在部30bに、浮き上がるような変形を生じさせる力F3が作用する
Similarly, as described above with reference to FIG. 2, when a rope is hung between the header board 2 and the tailgate 4 and tied together in the front-rear direction, an inward force from the outside of the cargo box to the inside of the cargo box is generated. F2 is added. This inward force F2 applies a force to the connecting portion between both ends of the header board 2 in the vehicle width direction and the inner surfaces of the pair of side gates 3, 3 in the vehicle width direction to close the connecting portion. . FIG. 13 is a partially cutaway side view of the fixed connection portion A when viewed from the vehicle width direction. When the above-mentioned inward force F2 is applied, as shown by the arrow in FIG. 13, there is a force that causes deformation such as lifting, especially on the extension portion 30b of the upper rail 30 on which the rope hook or the like is hung. F3 works
そこで、本実施形態では、ヘッダーボード2とサイドゲート3とを連結するブラケット10を設け、上記連結部分を補強している。
特に、本実施形態のブラケット10は、ブラケット10の一方側に設けられ、ヘッダーボード2の上部(アッパーレール30)に固定される第1固定部分11と、ブラケット10の他方側に設けられ、ヘッダーボード2よりも車両前方に位置するサイドゲート3の所定箇所(前側リンフォース40)に固定される第2固定部分12と、を有する。すなわち、ブラケット10の第1固定部分11と第2固定部分12とが車両前後方向にオフセットしている。したがって、第1固定部分11及び第2固定部分12において、外力の一部を剪断力として受けることができ、ブラケット10への負荷を軽減することができる。
また、第2固定部分12がヘッダーボード2よりも車両前方に位置するので、ブラケット10は車両荷箱1の収容領域外に位置され、車両荷箱1の収容容積を大きくできる。
また、ブラケット10が板状であることで、軽量化ができる。 Therefore, in this embodiment, abracket 10 is provided to connect the header board 2 and the side gate 3 to reinforce the connection portion.
In particular, thebracket 10 of this embodiment has a first fixed part 11 provided on one side of the bracket 10 and fixed to the upper part (upper rail 30) of the header board 2, and a first fixed part 11 provided on the other side of the bracket 10 and fixed to the header board 2. It has a second fixed portion 12 fixed to a predetermined location (front reinforcement 40) of the side gate 3 located further forward of the vehicle than the board 2. That is, the first fixed portion 11 and the second fixed portion 12 of the bracket 10 are offset in the vehicle longitudinal direction. Therefore, the first fixed portion 11 and the second fixed portion 12 can receive part of the external force as a shearing force, and the load on the bracket 10 can be reduced.
Further, since the second fixedportion 12 is located further forward of the vehicle than the header board 2, the bracket 10 is located outside the storage area of the vehicle cargo box 1, and the storage capacity of the vehicle cargo box 1 can be increased.
Furthermore, since thebracket 10 is plate-shaped, it can be made lighter.
特に、本実施形態のブラケット10は、ブラケット10の一方側に設けられ、ヘッダーボード2の上部(アッパーレール30)に固定される第1固定部分11と、ブラケット10の他方側に設けられ、ヘッダーボード2よりも車両前方に位置するサイドゲート3の所定箇所(前側リンフォース40)に固定される第2固定部分12と、を有する。すなわち、ブラケット10の第1固定部分11と第2固定部分12とが車両前後方向にオフセットしている。したがって、第1固定部分11及び第2固定部分12において、外力の一部を剪断力として受けることができ、ブラケット10への負荷を軽減することができる。
また、第2固定部分12がヘッダーボード2よりも車両前方に位置するので、ブラケット10は車両荷箱1の収容領域外に位置され、車両荷箱1の収容容積を大きくできる。

さらに、ブラケット10は、第1固定部分11と第2固定部分12とを接続し、車幅方向に向かうにつれて車両上下方向に傾斜する接続部13を有する。したがって、ブラケット10への負荷を分散させることができる。なお、図8に破線Dで示したように、仮にブラケット10が傾斜する接続部13を備えず、第1固定部分11と第2固定部分12とが垂直に接続する形状とした場合、第1固定部分11と第2固定部分12とを連結する角部に負荷が集中してしまう。この場合、ブラケット10自体の強度を増す必要が生じ、板厚の増加やビード形状を追加する等によって重量アップやコストアップの要因となってしまうので好ましくない。
また、接続部13で接続された第1固定部分11と第2固定部分12は、車両前後方向のオフセットに加え、車両上下方向及び車幅方向にもオフセットするので、第1固定部分11(第1固定点P1)と第2固定部分12(第2固定点P2)との位置関係が三次元となる。したがって、第1固定部分11(第1固定点P1)と第2固定部分12(第2固定点P2)に生じる応力は、前後方向、上下方向、車幅方向に分散し易くなる。この結果、ブラケット10の応力分散の機能がより高まり、変形防止効果を高めることができる。 Furthermore, thebracket 10 has a connecting portion 13 that connects the first fixed portion 11 and the second fixed portion 12 and is inclined in the vehicle vertical direction as it goes in the vehicle width direction. Therefore, the load on the bracket 10 can be distributed. Note that, as shown by the broken line D in FIG. The load will be concentrated on the corner that connects the fixed part 11 and the second fixed part 12. In this case, it becomes necessary to increase the strength of the bracket 10 itself, and increasing the plate thickness or adding a bead shape causes an increase in weight and cost, which is not preferable.
In addition, the first fixedportion 11 and the second fixed portion 12 connected at the connecting portion 13 are offset not only in the vehicle longitudinal direction but also in the vehicle vertical direction and vehicle width direction. The positional relationship between the first fixed point P1) and the second fixed part 12 (second fixed point P2) is three-dimensional. Therefore, the stress generated in the first fixed portion 11 (first fixed point P1) and the second fixed portion 12 (second fixed point P2) is easily dispersed in the longitudinal direction, the vertical direction, and the vehicle width direction. As a result, the stress dispersion function of the bracket 10 is further enhanced, and the deformation prevention effect can be enhanced.
また、接続部13で接続された第1固定部分11と第2固定部分12は、車両前後方向のオフセットに加え、車両上下方向及び車幅方向にもオフセットするので、第1固定部分11(第1固定点P1)と第2固定部分12(第2固定点P2)との位置関係が三次元となる。したがって、第1固定部分11(第1固定点P1)と第2固定部分12(第2固定点P2)に生じる応力は、前後方向、上下方向、車幅方向に分散し易くなる。この結果、ブラケット10の応力分散の機能がより高まり、変形防止効果を高めることができる。 Furthermore, the
In addition, the first fixed
ブラケット10の第1固定部分11とヘッダーボード2の上部(アッパーレール30)とが固定される第1固定点P1と、ブラケット10の第2固定部分12とサイドゲート3の所定箇所(前側リンフォース40)とが固定される第2固定点P2とが、車両前後方向にオフセットしている。したがって、外力を効率よく受けることができる。
特に、図13で示したように、アッパーレール30の延在部30bに浮き上がるような変形を生じさせる力F3が作用する場合に、ブラケット10への負荷を軽減することができる。仮に、第1固定点P1と第2固定点P2とが、車両前後方向に同一位置である場合、第1固定点P1と第2固定点P2とを結んだ線と、車両後方に向かう力F3と、が垂直になってしまい、効率良く負荷を受けることが困難である。 A first fixing point P1 where the firstfixed part 11 of the bracket 10 and the upper part of the header board 2 (upper rail 30) are fixed, and a predetermined point P1 where the second fixed part 12 of the bracket 10 and the side gate 3 (front reinforcement) are fixed. 40) and the second fixed point P2 to which are fixed are offset in the longitudinal direction of the vehicle. Therefore, external force can be efficiently received.
In particular, as shown in FIG. 13, when a force F3 that causes theextension portion 30b of the upper rail 30 to deform in a floating manner acts on it, the load on the bracket 10 can be reduced. If the first fixed point P1 and the second fixed point P2 are at the same position in the longitudinal direction of the vehicle, the line connecting the first fixed point P1 and the second fixed point P2 and the force F3 directed toward the rear of the vehicle and are vertical, making it difficult to receive the load efficiently.
特に、図13で示したように、アッパーレール30の延在部30bに浮き上がるような変形を生じさせる力F3が作用する場合に、ブラケット10への負荷を軽減することができる。仮に、第1固定点P1と第2固定点P2とが、車両前後方向に同一位置である場合、第1固定点P1と第2固定点P2とを結んだ線と、車両後方に向かう力F3と、が垂直になってしまい、効率良く負荷を受けることが困難である。 A first fixing point P1 where the first
In particular, as shown in FIG. 13, when a force F3 that causes the
ヘッダーボード2の上部には、横断面形状が屈曲形状をなすアッパーレール30(第1補強部材)が、車幅方向に沿って設けられ、ブラケット10の第1固定部分11は、アッパーレール30に固定される。したがって、弱部となりやすいヘッダーボード2の上部を、ブラケット10に加えてアッパーレール30によって補強することができる。
At the top of the header board 2, an upper rail 30 (first reinforcing member) having a bent cross-sectional shape is provided along the vehicle width direction, and the first fixed portion 11 of the bracket 10 is attached to the upper rail 30. Fixed. Therefore, the upper part of the header board 2, which tends to be a weak part, can be reinforced by the upper rail 30 in addition to the bracket 10.
サイドゲート3の所定箇所には、前側リンフォース40(第2補強部材)が設けられ、ブラケット10の第2固定部分12は、前側リンフォース40に固定される。したがって、弱部となりやすいヘッダーボード2の所定箇所を、ブラケット10に加えて前側リンフォース40によって補強することができる
A front reinforcement 40 (second reinforcing member) is provided at a predetermined location of the side gate 3, and the second fixed portion 12 of the bracket 10 is fixed to the front reinforcement 40. Therefore, predetermined parts of the header board 2 that tend to be weak parts can be reinforced by the front reinforcement 40 in addition to the bracket 10.
サイドゲート3には、ヘッダーボード2よりも車両後方に、後側リンフォース50(第3補強部材)が設けられる。したがって、サイドゲート3を更に補強することができる。
A rear reinforcement 50 (third reinforcing member) is provided on the side gate 3 at a position further rearward of the vehicle than the header board 2. Therefore, the side gate 3 can be further reinforced.
前側リンフォース40は、車幅方向内側に延びる突片41を有し、突片41は、アッパーレール30と後側リンフォース50とで挟み込まれている、したがって、前側リンフォース40は、ブラケット10によるアッパーレール30への固定に加え、挟み込まれることによってアッパーレール30及び後側リンフォース50に固定されるので、ブラケット10への負荷を分散することができる。
The front reinforcement 40 has a projecting piece 41 extending inward in the vehicle width direction, and the projecting piece 41 is sandwiched between the upper rail 30 and the rear reinforcement 50. Therefore, the front reinforcement 40 In addition to being fixed to the upper rail 30 by the bracket 10, the bracket 10 is also fixed to the upper rail 30 and the rear reinforcement 50 by being sandwiched, so that the load on the bracket 10 can be distributed.
前側リンフォース40の突片41と後側リンフォース50とが固定される第3固定点P3は、車両上下方向においてブラケット10の第1固定部分11(第1固定点P1)と第2固定部分12(第2固定点P2)との間に位置する。したがって、三点固定となって負荷を分散できるとともに、3つの固定点P1,P2,P3がコンパクトに配置される。そして、この3つの固定点P1,P2,P3は、ブラケット10と三つの補強部材(アッパーレール30、前側リンフォース40、後側リンフォース50)とで直接連結されているので、連結固定部分A全体としての剛性を高めることができる。
The third fixing point P3 to which the protruding piece 41 of the front reinforcement 40 and the rear reinforcement 50 are fixed is the first fixing part 11 (first fixing point P1) and the second fixing part of the bracket 10 in the vehicle vertical direction. 12 (second fixed point P2). Therefore, the load can be distributed by fixing at three points, and the three fixing points P1, P2, and P3 are arranged compactly. These three fixed points P1, P2, and P3 are directly connected to the bracket 10 and the three reinforcing members (upper rail 30, front reinforcement 40, and rear reinforcement 50), so the connecting fixed portion A The overall rigidity can be increased.
上述の本実施形態の補強構造においては、3つの固定点P1,P2,P3は、前後方向、上下方向、及び車幅方向にオフセットした立体的配置となっているので、あらゆる方向の外力に対応して分散機能を高め、変形抑制の効果を向上できる。
In the above-described reinforcement structure of this embodiment, the three fixed points P1, P2, and P3 are three-dimensionally arranged offset in the longitudinal direction, vertical direction, and vehicle width direction, so that they can cope with external forces in all directions. This can enhance the dispersion function and improve the effect of suppressing deformation.
ブラケット10の接続部13には、ブラケット10の厚み方向への屈曲による稜線71~78が形成されている。これにより、ブラケット10の剛性が向上する。
The connecting portion 13 of the bracket 10 has ridgelines 71 to 78 formed by bending the bracket 10 in the thickness direction. This improves the rigidity of the bracket 10.
以上、本発明の実施形態について説明したが、本発明はその技術思想の範囲で適宜変更することができる。例えば、上記実施形態においては、ブラケット10の接続部13に第1~第5傾斜部21~25を設けた構造としたが、傾斜部の数については、これに何ら制限されるものではなく、また、各傾斜部の傾斜角度、形状等についても図示のものに制限されるものではない。
Although the embodiments of the present invention have been described above, the present invention can be modified as appropriate within the scope of its technical concept. For example, in the above embodiment, the connecting portion 13 of the bracket 10 has a structure in which the first to fifth sloped portions 21 to 25 are provided, but the number of sloped portions is not limited to this. Furthermore, the angle of inclination, shape, etc. of each inclined portion are not limited to those shown in the drawings.
