しかし、特許文献１の車両用開閉体では、主面部と側面部の間に、長尺状のインナーパネルリンフォースを上下方向に沿って設けている。すなわち、長尺状のインナーパネルリンフォースは、主面部から上下方向に延び側面部に固定され、ラッチリンフォースの両側に配置される。これによって、ラッチ取付部の剛性を確保するために、インナーパネルリンフォースが大型化する。この結果、車両用開閉体の重量が増加する。
However, in the vehicle opening / closing body of Patent Document 1, a long inner panel reinforcement is provided along the vertical direction between the main surface portion and the side surface portion. That is, the elongated inner panel reinforcement extends in the vertical direction from the main surface portion, is fixed to the side surface portion, and is arranged on both sides of the latch reinforcement. As a result, the inner panel reinforcement is increased in size in order to secure the rigidity of the latch mounting portion. As a result, the weight of the vehicle opening / closing body increases.
本開示の課題は、補強部材の軽量化を図りながらラッチ取付部の剛性を確保できる車両用開閉体を提供することにある。

第２補強部材１４は、図１に示すように、ラッチ取付部８ａを車幅方向Ｐに挟んで一対で設けられる。一対の第２補強部材１４は、それぞれラッチ８の車幅方向Ｐ左右両側でビード部１２とラッチリンフォース８ｂとを連結する。より具体的には、第２補強部材１４は、ビード部１２からラッチ取付部８ａまでビード部１２の延設方向に沿って延びるとともに、ビード部１２およびラッチ取付部８ａに固定される。これによって、第２補強部材１４は、ビード部１２とラッチ取付部８ａとの間に筋交い状に配置される。
As shown in FIG. 1, the second reinforcing member 14 is provided as a pair with the latch mounting portion 8a sandwiched in the vehicle width direction P. The pair of second reinforcing members 14 connect the bead portion 12 and the latch reinforcement 8b on both the left and right sides of the latch 8 in the vehicle width direction P. More specifically, the second reinforcing member 14 extends from the bead portion 12 to the latch mounting portion 8a along the extending direction of the bead portion 12, and is fixed to the bead portion 12 and the latch mounting portion 8a. As a result, the second reinforcing member 14 is arranged in a brace shape between the bead portion 12 and the latch mounting portion 8a.
第２補強部材１４は、長尺状であり、中央部６ｃを挟んで車幅方向Ｐに間隔を隔てて配置された左第２補強部材１４ａおよび右第２補強部材１４ｂを有する。本実施形態では、図３に示すように、第２補強部材１４は、ビード部１２の延びる方向に沿って直線状に延びる。左第２補強部材１４ａおよび右第２補強部材１４ｂのラッチリンフォース８ｂ側の端部（本実施形態では下端、一端の一例）は、ラッチ取付部８ａに接合されたラッチリンフォース８ｂの固定面８ｃに、接合または締結によって固定される。より具体的には、左第２補強部材１４ａおよび右第２補強部材１４ｂは、ビード部１２からラッチ取付部８ａに向けて、それぞれ下方に向って延びる。また、左第２補強部材１４ａおよび右第２補強部材１４ｂは、車幅方向Ｐの中央部６ｃに向けて、ビード部１２の傾斜に沿って傾斜して延びる。左第２補強部材１４ａおよび右第２補強部材１４ｂのビード部１２側の端部（本実施形態では上端、他端の一例）は、直線状に形成された左ビード部１２ａおよび右ビード部１２ｂに、接合または締結によって固定される。
The second reinforcing member 14 has a long shape and has a left second reinforcing member 14a and a right second reinforcing member 14b arranged at intervals in the vehicle width direction P with the central portion 6c interposed therebetween. In the present embodiment, as shown in FIG. 3, the second reinforcing member 14 extends linearly along the extending direction of the bead portion 12. The ends of the left second reinforcing member 14a and the right second reinforcing member 14b on the latch reinforcement 8b side (in this embodiment, the lower end and one end are examples) are the fixing surfaces of the latch reinforcement 8b joined to the latch mounting portion 8a. It is fixed to 8c by joining or fastening. More specifically, the left second reinforcing member 14a and the right second reinforcing member 14b extend downward from the bead portion 12 toward the latch mounting portion 8a, respectively. Further, the left second reinforcing member 14a and the right second reinforcing member 14b are inclined and extended along the inclination of the bead portion 12 toward the central portion 6c in the vehicle width direction P. The ends of the left second reinforcing member 14a and the right second reinforcing member 14b on the bead portion 12 side (an example of the upper end and the other end in this embodiment) are linearly formed left bead portions 12a and right bead portions 12b. Is fixed by joining or fastening.
図４に示す第２補強部材１４は、左第２補強部材１４ａである。なお、本実施形態では、右第２補強部材１４ｂは、左第２補強部材１４ａと左右対称形状のため説明を省略する。図４に示すように、左第２補強部材１４ａは、第１延設面１４ｃと、第２延設面１４ｄと、取付面１４ｅと、回り止め１４ｆと、を有する。第１延設面１４ｃは、主面部６に沿って延びる。第２延設面１４ｄは、アウターパネル４に向かって車両用開閉体１の厚み方向に延びる。取付面１４ｅは、ラッチリンフォース８ｂに沿って延びる。取付面１４ｅは、ラッチリンフォース８ｂに凹んで形成された固定面８ｃに接合または締結によって固定される。回り止め１４ｆは、第１延設面１４ｃから車幅方向Ｐに延び、主面部６と接することで、左第２補強部材１４ａが上下方向Ｇに回転することを防止する。
The second reinforcing member 14 shown in FIG. 4 is the left second reinforcing member 14a. In the present embodiment, the right second reinforcing member 14b has a symmetrical shape with the left second reinforcing member 14a, and thus the description thereof will be omitted. As shown in FIG. 4, the left second reinforcing member 14a has a first extending surface 14c, a second extending surface 14d, a mounting surface 14e, and a detent 14f. The first extending surface 14c extends along the main surface portion 6. The second extending surface 14d extends in the thickness direction of the vehicle opening / closing body 1 toward the outer panel 4. The mounting surface 14e extends along the latch reinforcement 8b. The mounting surface 14e is fixed to the fixing surface 8c recessed in the latch reinforcement 8b by joining or fastening. The detent 14f extends from the first extending surface 14c in the vehicle width direction P and comes into contact with the main surface portion 6 to prevent the left second reinforcing member 14a from rotating in the vertical direction G.
第１延設面１４ｃは、ビード部１２の頂面１２ｃに沿って延びる。図５は、左第２補強部材１４ａのビード部１２側の端部における、左ビード部１２ａおよび左第２補強部材１４ａの長手方向を横切る横断面図である。図５は、左ビード部１２ａと左第２補強部材１４ａとの固定状態を示している。図５に示すように、左第２補強部材１４ａの第１延設面１４ｃは、左第２補強部材１４ａのビード部１２側の端部において、ビード部１２の頂面１２ｃと接合または締結によって固定される。
The first extended surface 14c extends along the top surface 12c of the bead portion 12. FIG. 5 is a cross-sectional view crossing the longitudinal direction of the left bead portion 12a and the left second reinforcing member 14a at the end portion of the left second reinforcing member 14a on the bead portion 12 side. FIG. 5 shows a fixed state between the left bead portion 12a and the left second reinforcing member 14a. As shown in FIG. 5, the first extending surface 14c of the left second reinforcing member 14a is joined or fastened to the top surface 12c of the bead portion 12 at the end portion of the left second reinforcing member 14a on the bead portion 12 side. Be fixed.
図４および図５に示すように、第２延設面１４ｄは、ビード部１２の側面１２ｄに沿って延び、第１延設面１４ｃとＬ字型の形状をなす。左第２補強部材１４ａの第２延設面１４ｄは、左第２補強部材１４ａのビード部１２側の端部において、ビード部１２の側面１２ｄに接合される。第２補強部材１４は、車両用開閉体１の厚み方向（本実施形態では前後方向Ｑ）での幅がラッチリンフォース８ｂに向かうにつれて大きくなるように形成される。本実施形態では、第２延設面１４ｄがラッチリンフォース８ｂに向かうにつれて、面積が大きくなる。すなわち、第２延設面１４ｄは、下方に向かうにつれてアウターパネル４に向けて延びる方向の長さが長くなる略三角形の形状である。第２延設面１４ｄは、略三角形の底辺が取付面１４ｅと繋がる。このように、第２延設面１４ｄは、第１延設面１４ｃおよび取付面１４ｅと繋がることで、第１延設面１４ｃと取付面１４ｅとの間の筋交いとして機能する。また、左第２補強部材１４ａは、主面部６およびラッチ取付部８ａに固定されるため、左第２補強部材１４ａが主面部６およびラッチ取付部８ａの筋交いとして機能する。
As shown in FIGS. 4 and 5, the second extending surface 14d extends along the side surface 12d of the bead portion 12 and forms an L-shape with the first extending surface 14c. The second extended surface 14d of the left second reinforcing member 14a is joined to the side surface 12d of the bead portion 12 at the end portion of the left second reinforcing member 14a on the bead portion 12 side. The second reinforcing member 14 is formed so that the width of the vehicle opening / closing body 1 in the thickness direction (the front-rear direction Q in the present embodiment) increases toward the latch reinforcement 8b. In the present embodiment, the area increases as the second extending surface 14d approaches the latch reinforcement 8b. That is, the second extending surface 14d has a substantially triangular shape in which the length in the direction extending toward the outer panel 4 becomes longer as it goes downward. On the second extended surface 14d, the base of a substantially triangular shape is connected to the mounting surface 14e. In this way, the second extending surface 14d functions as a brace between the first extending surface 14c and the mounting surface 14e by connecting to the first extending surface 14c and the mounting surface 14e. Further, since the left second reinforcing member 14a is fixed to the main surface portion 6 and the latch mounting portion 8a, the left second reinforcing member 14a functions as a brace between the main surface portion 6 and the latch mounting portion 8a.
このように、第２補強部材１４とビード部１２を直線状に設けて、ラッチ取付部８ａと左側部リンフォース１６ａおよび右側部リンフォース１６ｂとを直線状に結ぶことで、ラッチ取付部８ａがビード部１２および第２補強部材１４の両方によって押さえられる。これによって、一対のビード部１２によって主面部６の面剛性を効率よく向上させることができる。さらに、ラッチ８を介して入力された荷重は、主面部６において他の部分よりも剛性が高く、荷重が比較的効率的に伝達する側端部側に逃げる。この結果、特許文献１のテールゲートのように第２補強部材１４がラッチ取付部８ａを挟んで車幅方向Ｐの両側に設けられるよりも、第２補強部材１４を小さくできる。このため、第２補強部材１４を軽量化しながらも、剛性を確保できる。また、車両用開閉体１をこのような構造とすることで、ラッチ取付部８ａにかかる負荷をビード部１２および第２補強部材１４の両方で受け、左側部リンフォース１６ａおよび右側部リンフォース１６ｂに伝達することができる。これによって、ラッチ８を介して入力された荷重をより効率よく確実に側端部に逃がすことができる。さらに、第２補強部材１４は、筋交いとして機能するため、ラッチ取付部８ａの剛性を確保しやすい。この結果、ラッチリンフォース８ｂ、第２補強部材１４、左側部リンフォース１６ａ、および右側部リンフォース１６ｂを含むインナーパネル２を補強する補強部材の全てが軽量化しやすい。
In this way, the second reinforcing member 14 and the bead portion 12 are provided in a straight line, and the latch mounting portion 8a is linearly connected to the left side portion reinforcement 16a and the right side portion reinforcement 16b, whereby the latch mounting portion 8a is formed. It is held down by both the bead portion 12 and the second reinforcing member 14. As a result, the surface rigidity of the main surface portion 6 can be efficiently improved by the pair of bead portions 12. Further, the load input via the latch 8 has higher rigidity in the main surface portion 6 than the other portions, and escapes to the side end portion side where the load is transmitted relatively efficiently. As a result, the second reinforcing member 14 can be made smaller than the second reinforcing member 14 provided on both sides in the vehicle width direction P with the latch mounting portion 8a interposed therebetween as in the tailgate of Patent Document 1. Therefore, the rigidity can be ensured while reducing the weight of the second reinforcing member 14. Further, by having the vehicle opening / closing body 1 having such a structure, the load applied to the latch mounting portion 8a is received by both the bead portion 12 and the second reinforcing member 14, and the left side portion reinforcement 16a and the right side portion reinforcement 16b are received. Can be communicated to. As a result, the load input via the latch 8 can be more efficiently and reliably released to the side end portion. Further, since the second reinforcing member 14 functions as a brace, it is easy to secure the rigidity of the latch mounting portion 8a. As a result, all of the reinforcing members for reinforcing the inner panel 2 including the latch reinforcement 8b, the second reinforcing member 14, the left side reinforcement 16a, and the right side reinforcement 16b can be easily reduced in weight.
以上説明した通り、本開示によれば、軽量化を図りながらラッチ取付部８ａの剛性を確保できる車両用開閉体１を提供できる。
As described above, according to the present disclosure, it is possible to provide a vehicle opening / closing body 1 capable of ensuring the rigidity of the latch mounting portion 8a while reducing the weight.
