Provided is a reinforcing structure characterized in that it has a third plate portion that is

前記第２板部は、前記第１板部の振動を抑制する方向に延伸していてもよい。また、前記第２板部は、前記第１板部と直交していてもよい。また、前記補強部材の前記車両の前後方向における幅は、前記外板の前記車両の前後方向における幅及び前記内板の前記車両の前後方向における幅よりも小さくてもよい。また、前記外板と前記内板とは、前記第１板部の上端の位置において接続されていてもよい。また、前記内板の下端は、前記外板の下端よりも、前記車両の高さ方向において高い位置にあってもよい。 The second plate portion may extend in a direction that suppresses vibration of the first plate portion. Further, the second plate portion may be orthogonal to the first plate portion. Further, the width of the reinforcing member in the longitudinal direction of the vehicle may be smaller than the width of the outer plate in the longitudinal direction of the vehicle and the width of the inner plate in the longitudinal direction of the vehicle. Further, the outer plate and the inner plate may be connected at an upper end position of the first plate portion. Moreover, the lower end of the inner plate may be located at a higher position in the height direction of the vehicle than the lower end of the outer plate.

本開示によれば、補強構造において、内板に振動が発生した際に、内板の振動を抑制することができるという効果を奏する。 According to the present disclosure, in the reinforcing structure, when vibration occurs in the inner plate, the vibration of the inner plate can be suppressed.

車両は、例えばＳＵＶ（Ｓｐｏｒｔ Ｕｔｉｌｉｔｙ Ｖｅｈｉｃｌｅ）である。図１に示すように、車両は、車両の側部後方に位置する領域Ａ付近に補強構造１を有する。 The vehicle is, for example, an SUV (Sport Utility Vehicle). As shown in FIG. 1, the vehicle has a reinforcing structure 1 near a region A located at the rear side of the vehicle.

［補強構造１の詳細構成］
図２及び図３に示すように、補強構造１は、外板（ボディサイドアウタ）１１、内板（クウォーターアッパーインナ）１２、及び補強部材（スティフナ）１３を有する。補強部材１３は、外板１１の変形やべこつきの発生を防ぐための部材である。また、補強部材１３は、内板１２に振動が発生した際に、内板１２の振動を抑制する機能も有する。 [Detailed configuration of reinforcement structure 1]
As shown in FIGS. 2 and 3, the reinforcing structure 1 includes an outer plate (body side outer) 11, an inner plate (quarter upper inner) 12, and a reinforcing member (stiffener) 13. The reinforcing member 13 is a member for preventing the outer panel 11 from deforming or becoming sticky. Further, the reinforcing member 13 also has a function of suppressing vibration of the inner plate 12 when vibration occurs in the inner plate 12.

外板１１は、車両の車幅方向における側面を形成する板である。外板１１は、開口部１１１と切り欠き部１１２とを有する。開口部１１１は、車両の窓に対応する位置に形成されている。切り欠き部１１２は、外板１１の下縁に形成されている略半円状の凹部である。切り欠き部１１２には、車両の後輪が位置する。 The outer plate 11 is a plate that forms a side surface of the vehicle in the vehicle width direction. The outer plate 11 has an opening 111 and a notch 112. The opening 111 is formed at a position corresponding to a vehicle window. The cutout portion 112 is a substantially semicircular recess formed at the lower edge of the outer panel 11. A rear wheel of the vehicle is located in the notch 112.

内板１２は、外板１１よりも車両の車幅方向における内側に設けられている板である。内板１２は、開口部１２１を有する。開口部１２１は、車両の窓に対応する位置に形成されている。開口部１１１と開口部１２１とは同じ形状であり、外板１１の開口部１１１と内板１２の開口部１２１とは、車両の前後方向及び車両の高さ方向において同じ位置にある。開口部１１１及び開口部１２１の形状は任意である。 The inner plate 12 is a plate provided inside the outer plate 11 in the vehicle width direction. The inner plate 12 has an opening 121. The opening 121 is formed at a position corresponding to a vehicle window. The opening 111 and the opening 121 have the same shape, and the opening 111 of the outer panel 11 and the opening 121 of the inner panel 12 are located at the same position in the longitudinal direction of the vehicle and the height direction of the vehicle. The shapes of the opening 111 and the opening 121 are arbitrary.

内板１２の車両の高さ方向における長さは、外板１１の車両の高さ方向における長さよりも小さい。内板１２の下端は、外板１１の下端よりも、車両の高さ方向において高い位置にある。また、内板１２の車両の前後方向における後端は、外板１１の車両の前後方向における後端よりも前方に位置する。 The length of the inner plate 12 in the height direction of the vehicle is smaller than the length of the outer plate 11 in the height direction of the vehicle. The lower end of the inner plate 12 is located at a higher position than the lower end of the outer plate 11 in the height direction of the vehicle. Further, the rear end of the inner plate 12 in the longitudinal direction of the vehicle is located further forward than the rear end of the outer plate 11 in the longitudinal direction of the vehicle.

補強部材１３は、外板１１と内板１２とを接続する部材である。図３に示すように、補強部材１３は、第１板部１３１、第２板部１３２、及び第３板部１３３を有する。第１板部１３１は、内板１２に沿って、少なくとも内板１２の下端まで延伸している。具体的には、第１板部１３１は、内板１２の車両の車幅方向における外側の面又は内側の面に溶接されている。第１板部１３１の上端は、車両の高さ方向において、例えば開口部１１１及び開口部１２１の下縁の位置と同じ高さに位置する。 The reinforcing member 13 is a member that connects the outer plate 11 and the inner plate 12. As shown in FIG. 3, the reinforcing member 13 has a first plate part 131, a second plate part 132, and a third plate part 133. The first plate portion 131 extends along the inner plate 12 to at least the lower end of the inner plate 12 . Specifically, the first plate portion 131 is welded to an outer surface or an inner surface of the inner plate 12 in the vehicle width direction of the vehicle. The upper end of the first plate portion 131 is located at the same height as the lower edges of the openings 111 and 121, for example, in the height direction of the vehicle.

第２板部１３２は、第１板部１３１の下端から、第１板部１３１から車両の外側に向けて延伸している。第３板部１３３は、第２板部１３２の車両の車幅方向における外側の端部から下方に向かって外板１１に沿って延伸している。具体的には、第３板部１３３は、外板１１の車両の車幅方向における内側の面に接着されている。第３板部１３３の下端は、車両の高さ方向において、外板１１の下端と同じ位置であるか、または外板１１の下端よりも高い位置にある。また、第３板部１３３は、複数の開口部１３３１が形成されていることで、軽量化することができる。開口部１３３１の数、及び形状は任意である。 The second plate portion 132 extends from the lower end of the first plate portion 131 toward the outside of the vehicle. The third plate portion 133 extends downward along the outer panel 11 from the outer end of the second plate portion 132 in the vehicle width direction of the vehicle. Specifically, the third plate portion 133 is bonded to the inner surface of the outer panel 11 in the vehicle width direction. The lower end of the third plate portion 133 is at the same position as the lower end of the outer panel 11 or at a higher position than the lower end of the outer panel 11 in the height direction of the vehicle. Further, the third plate portion 133 can be made lighter by forming the plurality of openings 1331. The number and shape of the openings 1331 are arbitrary.

図３に示すように、外板１１と内板１２とは、第１板部１３１の上端の位置において接続されている。具体的には、補強部材１３の第１板部１３１の上端は、外板１１の上端と内板１２の上端とに挟まれて溶接されている。内板１２は、車両の高さ方向において延伸している。また、外板１１は、第１板部１３１の上端の位置から下方に向かうにつれて徐々に内板１２からの距離が大きくなるように車両の車幅方向における外側向きに傾斜して湾曲している。 As shown in FIG. 3, the outer plate 11 and the inner plate 12 are connected at the upper end of the first plate portion 131. As shown in FIG. Specifically, the upper end of the first plate portion 131 of the reinforcing member 13 is sandwiched between and welded to the upper end of the outer plate 11 and the upper end of the inner plate 12. The inner plate 12 extends in the height direction of the vehicle. Further, the outer plate 11 is inclined and curved outward in the vehicle width direction so that the distance from the inner plate 12 gradually increases as it goes downward from the upper end position of the first plate part 131. .

外板１１、内板１２、及び補強部材１３を有する補強構造１は、車両に生ずる振動（例えば車両のエンジンの振動、または路面を走行することにより生ずる振動）によって、振動する。特に、内板１２は、上述したように内板１２の高さ方向における第１板部１３１の上端の位置において、外板１１と接続されている。そして、内板１２の高さ方向における下端が、車両の水平方向において、内板１２の高さ方向における下端の位置における外板１１の位置から所定の距離離れている。よって、内板１２の下端部は、内板１２の車両の高さ方向における第１板部１３１の上端の位置を支点として車両に生ずる振動によって大きく振動し易い。 The reinforcing structure 1, which includes the outer plate 11, the inner plate 12, and the reinforcing member 13, vibrates due to vibrations generated in the vehicle (for example, vibrations from the vehicle's engine or vibrations generated by driving on a road surface). In particular, the inner plate 12 is connected to the outer plate 11 at the upper end position of the first plate portion 131 in the height direction of the inner plate 12, as described above. The lower end of the inner plate 12 in the height direction is spaced a predetermined distance from the position of the outer plate 11 at the lower end of the inner plate 12 in the height direction in the horizontal direction of the vehicle. Therefore, the lower end of the inner plate 12 is likely to vibrate greatly due to vibrations generated in the vehicle with the upper end of the first plate portion 131 of the inner plate 12 in the height direction of the vehicle as a fulcrum.

しかし、補強部材１３が内板１２に沿って、少なくとも内板１２の下端まで延伸している第１板部１３１を有するので、内板１２の下端部は、振動が抑制される。 However, since the reinforcing member 13 has the first plate portion 131 extending along the inner plate 12 to at least the lower end of the inner plate 12, vibrations at the lower end of the inner plate 12 are suppressed.

図３に示すように、第２板部１３２は、第１板部１３１と直交しているが、第２板部１３２は、第１板部１３１の振動を抑制する方向に、第１板部１３１に対して所定の角度で傾斜して延伸していてもよい。第２板部１３２が、第１板部１３１と直交しているとき、補強部材１３は、車両の水平方向における強度が最も大きくなり、振動を抑制する力も大きくなる。 As shown in FIG. 3, the second plate part 132 is orthogonal to the first plate part 131, but the second plate part 132 is arranged so that the first plate part It may be extended at a predetermined angle with respect to 131. When the second plate part 132 is perpendicular to the first plate part 131, the strength of the reinforcing member 13 in the horizontal direction of the vehicle is the greatest, and the force for suppressing vibration is also increased.

また、補強部材１３の車両の前後方向における幅は、外板１１の車両の前後方向における幅及び内板１２の車両の前後方向における幅よりも小さい。 Further, the width of the reinforcing member 13 in the longitudinal direction of the vehicle is smaller than the width of the outer plate 11 in the longitudinal direction of the vehicle and the width of the inner plate 12 in the longitudinal direction of the vehicle.

なお、上記の実施形態においては、第１板部１３１は、内板１２に沿って、少なくとも内板１２の下端まで延伸しているとしたが、第１板部１３１は、内板１２に沿って、内板１２の下端よりも所定の範囲上方の位置まで延伸していてもよい。 In the above embodiment, the first plate part 131 extends along the inner plate 12 to at least the lower end of the inner plate 12; however, the first plate part 131 extends along the inner plate 12. The inner plate 12 may extend to a position above the lower end of the inner plate 12 by a predetermined range.

［本実施形態に係る補強構造１による効果］
本実施形態に係る補強構造１は、車両の車幅方向における側面を形成する外板１１と、外板１１よりも車両の車幅方向における内側に設けられている内板１２と、外板１１と内板１２とを接続する補強部材１３と、を有する。そして、補強部材１３は、内板１２に沿って、少なくとも内板１２の下端まで延伸している第１板部１３１と、第１板部１３１の下端から、第１板部１３１から車両の外側に向けて延伸している第２板部１３２と、第２板部１３２の車両の車幅方向における外側の端部から下方に向かって外板１１に沿って延伸している第３板部１３３と、を有する。 [Effects of reinforcement structure 1 according to this embodiment]
The reinforcing structure 1 according to the present embodiment includes an outer panel 11 forming a side surface of a vehicle in the vehicle width direction, an inner panel 12 provided inside the outer panel 11 in the vehicle width direction, and an outer panel 11. and a reinforcing member 13 connecting the inner plate 12 and the inner plate 12. The reinforcing member 13 includes a first plate part 131 extending along the inner plate 12 to at least the lower end of the inner plate 12, and a first plate part 131 extending from the lower end of the first plate part 131 to the outer side of the vehicle. a second plate portion 132 extending toward the outer panel 11; and a third plate portion 133 extending downward along the outer panel 11 from the outer end of the second plate portion 132 in the vehicle width direction. and has.

本実施形態に係る補強構造１は、このように内板１２に沿って、少なくとも内板１２の下端まで延伸している第１板部１３１を有する。よって、例えば車両のエンジンの振動、または路面を走行することにより生ずる車両の振動によって、内板１２が振動した際にも、内板１２が振動しづらくすることができる。 The reinforcing structure 1 according to the present embodiment has the first plate portion 131 extending along the inner plate 12 to at least the lower end of the inner plate 12 in this way. Therefore, even when the inner plate 12 vibrates due to, for example, vibrations of the vehicle's engine or vibrations of the vehicle caused by driving on a road surface, the inner plate 12 can be made less likely to vibrate.
