　本開示は、高電圧部品の支持構造に関する。 The present disclosure relates to a support structure for high voltage components.
　エンジンとモータとが組み合わされた駆動源（パワーユニット）が搭載されるハイブリッド車両（ＨＶ）やプラグインハイブリッド車両（ＰＨＥＶ）では、収容スペースや高電圧線のレイアウトの関係上、モータを制御するパワー制御ユニット等（インバータ等）の高電圧部品がパワーユニットの上方に配置されるレイアウトが採られているものがある。
このような車両では、車体部材に強電部品（例えば、インバータ）がブラケットを介して車体部材に支持されている。特許文献１には、強電部品と車両前方側の車体部材との間に延設されて強電部品を支持するブラケットが開示されている。かかるブラケットは、板状で、車体側の支持部及び強電部品の双方に対して少なくとも一部が重なり合うよう凸に屈曲形成された突出部を備えており、車両の衝突時に強電部品への衝撃を緩衝する構造となっている。 In hybrid vehicles (HV) and plug-in hybrid vehicles (PHEV) equipped with a drive source (power unit) that combines an engine and a motor, power control that controls the motor is required due to the layout of the accommodation space and high voltage lines. Some layouts are such that high-voltage components such as units (inverters, etc.) are arranged above the power unit.
In such a vehicle, a heavy electric component (for example, an inverter) is supported by a vehicle body member via a bracket. Patent Literature 1 discloses a bracket that extends between a high-voltage component and a vehicle body member on the front side of the vehicle to support the high-voltage component. Such a bracket is plate-shaped and has a projecting portion that is convexly bent so that at least a portion of the bracket overlaps both the support portion on the vehicle body side and the high-voltage component, and absorbs the impact on the high-voltage component in the event of a vehicle collision. It has a buffer structure.

　図５－１～図５－３は、車両の衝突による高電圧部品１の支持構造２の挙動を示す側面図であり、図６－１～図６－３は、フロントブラケット５の折れ曲がり挙動を示す平面図である。 5-1 to 5-3 are side views showing the behavior of the support structure 2 for the high-voltage component 1 due to a vehicle collision, and FIGS. 6-1 to 6-3 show the bending behavior of the front bracket 5. It is a plan view showing.
　図５－１に示すように、高電圧部品１はパワーユニット４の上方域に設置され、高電圧部品１は前部収容空間３の前部車体部材３３と高電圧部品１との間で両者を連結するフロントブラケット５に支持される。図５－２に示すように、車両が衝突すると前部収容空間３の前部車体部材３３が車両前後方向後方に後退する。このとき、フロントブラケット５は、車体固定部５１１と部品固定部５１３との間の上面部５１の変形誘発部５１５ａを起点に折れ曲がり始めるとともに（図６－２参照）、フロントブラケット５の前部車体部材３３側が上方に押し上げられる（図５－２参照）。図５－３に示すように、車両の衝突が進むと前部収容空間３の前部車体部材３３が車両前後方向後方にさらに後退する。このとき、フロントブラケット５の折れ曲がりは進み、車体固定部５１１の境界又は部品固定部５１３の境界のいずれかでも折れ曲がり始め（図６－３参照）、フロントブラケット５はＺ字状に折れ曲がる（図５－３参照）。 As shown in FIG. 5-1, the high voltage component 1 is installed in the upper region of the power unit 4, and the high voltage component 1 is sandwiched between the front body member 33 of the front housing space 3 and the high voltage component 1. It is supported by the connected front bracket 5 . As shown in FIG. 5-2, when the vehicle collides, the front body member 33 of the front accommodation space 3 retreats rearward in the vehicle longitudinal direction. At this time, the front bracket 5 starts to bend starting from the deformation inducing portion 515a of the upper surface portion 51 between the vehicle body fixing portion 511 and the part fixing portion 513 (see FIG. 6-2), and the front portion of the front vehicle body of the front bracket 5 The member 33 side is pushed upward (see FIG. 5-2). As shown in FIG. 5-3, as the collision of the vehicle progresses, the front vehicle body member 33 of the front accommodation space 3 further retreats rearward in the vehicle front-rear direction. At this time, the bending of the front bracket 5 progresses, and it begins to bend at either the boundary of the vehicle body fixing portion 511 or the boundary of the component fixing portion 513 (see FIG. 6-3), and the front bracket 5 bends in a Z shape (FIG. 5). -3).
　上述した本発明の実施形態に係る高電圧部品１の支持構造２によれば、車両の前突により前部車体部材３３が後退すると、フロントブラケット５の上面部５１に設けられた変形誘発部５１５ａを起点としてフロントブラケット５が折れ曲がる（変形する）。これにより、衝突による衝撃を吸収しつつ、高電圧部品１の後退をコントロールして高電圧部品１とパワーユニット４の干渉を抑制することができる。 According to the support structure 2 for the high-voltage component 1 according to the embodiment of the present invention described above, when the front vehicle body member 33 retreats due to a frontal collision of the vehicle, the deformation inducing portion 515a provided on the upper surface portion 51 of the front bracket 5 is deformed. , the front bracket 5 is bent (deformed). As a result, it is possible to suppress the interference between the high-voltage component 1 and the power unit 4 by controlling the retraction of the high-voltage component 1 while absorbing the impact caused by the collision.
　また、フランジ部５５には、車両前後方向において上面部５１の変形誘発部５１５ａの位置に対応して切り欠き５５０ａが設けられているので、変形誘発部５１５ａを変形の起点とする折れ曲がり（変形）を容易にする。これにより、高電圧部品１の後退（変位）をコントロールして高電圧部品１とパワーユニット４の干渉を抑制することができる。 Further, the flange portion 55 is provided with a notch 550a corresponding to the position of the deformation inducing portion 515a of the upper surface portion 51 in the vehicle front-rear direction. make it easier. Thereby, it is possible to control the retraction (displacement) of the high-voltage component 1 and suppress the interference between the high-voltage component 1 and the power unit 4 .
　また、側面部５３には、車両前後方向において上面部５１の変形誘発部５１５ａの位置に対応して穴５３０ａが形成されているので、変形誘発部５１５ａを変形の起点とする折れ曲がり（変形）を容易にする。これにより、高電圧部品１の後退（変位）をコントロールして高電圧部品１とパワーユニット４の干渉を抑制することができる。 In addition, since a hole 530a is formed in the side surface portion 53 so as to correspond to the position of the deformation inducing portion 515a of the upper surface portion 51 in the longitudinal direction of the vehicle, bending (deformation) with the deformation inducing portion 515a as a starting point of deformation can be prevented. make it easier. Thereby, it is possible to control the retraction (displacement) of the high-voltage component 1 and suppress the interference between the high-voltage component 1 and the power unit 4 .
　また、側面部５３は、その上下幅がフロントブラケット５の前端から略一定の幅で形成された後、後方に行くに従って次第に下方に向かって拡幅され、上下幅の拡幅が始まる位置５３Ｐが変形誘発部５１５ａの後方に位置されるので、上下幅の拡幅が始まる位置５３Ｐよりも後方における折れ曲がりを抑制する。これにより、変形誘発部５１５ａを起点とする折れ曲がり（変形）を容易にするので、高電圧部品１の後退（変位）をコントロールして高電圧部品１とパワーユニット４の干渉を抑制することができる。 In addition, the side portion 53 has a substantially constant vertical width from the front end of the front bracket 5, and then gradually widens downward as it goes rearward. Since it is positioned behind the portion 515a, it suppresses bending behind the position 53P where the expansion of the vertical width starts. This facilitates bending (deformation) starting from the deformation inducing portion 515a, so that the high-voltage component 1 can be controlled to retreat (displacement) and interference between the high-voltage component 1 and the power unit 4 can be suppressed.
　また、切り欠き凹部５１５の車両前後方向の両端から互いに近付く方向に向けて漸次幅が狭くなるよう形成され、幅の最も狭くなる位置を変形誘発部５１５ａとするので、フロントブラケット５は、上面部５１の切り欠き凹部５１５の幅の最も狭くなる位置を起点として折れ曲がる。これにより、高電圧部品１の後退（変位）をコントロールして高電圧部品とパワーユニットの干渉を抑制することができる。 In addition, the cutout recesses 515 are formed such that the width thereof gradually narrows in the direction toward each other from both ends thereof in the longitudinal direction of the vehicle, and the position where the width becomes narrowest is the deformation inducing portion 515a. It bends starting from the position where the width of the cutout recess 515 of 51 is the narrowest. As a result, the retraction (displacement) of the high-voltage component 1 can be controlled to suppress interference between the high-voltage component and the power unit.
　また、切り欠き凹部５１５は、車幅方向において側部車体部材３１に対向する側と反対側に設けられるので、車両の前突により前部車体部材３３が後退すると、フロントブラケット５は、サポートブラケット６が設けられる側部車体部材３１に向けて折れ曲がる。これにより、高電圧部品１の後退（変位）をコントロールして高電圧部品１とパワーユニット４の干渉を抑制することができる。 In addition, since the cutout recess 515 is provided on the side opposite to the side facing the side vehicle body member 31 in the vehicle width direction, when the front vehicle body member 33 retreats due to a frontal collision of the vehicle, the front bracket 5 becomes a support bracket. It bends toward the side body member 31 on which 6 is provided. Thereby, it is possible to control the retraction (displacement) of the high-voltage component 1 and suppress the interference between the high-voltage component 1 and the power unit 4 .

　図９－１～図９－３は、車両の衝突による高電圧部品１の支持構造２の挙動を示す図であり、図１０－１～図１０－３は、サイドブラケット７の折れ曲がり挙動を示す平面図である。 9-1 to 9-3 are diagrams showing the behavior of the support structure 2 for the high-voltage component 1 due to a vehicle collision, and FIGS. 10-1 to 10-3 show the bending behavior of the side bracket 7. It is a top view.
　図９－１に示すように、高電圧部品１はパワーユニット４の上方域に設置され、高電圧部品１は前部収容空間３の側部車体部材３１と高電圧部品１との間に設けられたサイドブラケット７に支持される。図９－２に示すように、車体が衝突すると前部収容空間３の前部車体部材３３が車両前後方向後方に後退し、高電圧部品１を後方に押し出すことがある。このとき、サイドブラケット７は、接続部７５及び接続部７５の周りにおいて変形を開始する（図９－２及び図１０－２参照）。たとえば、接続部７５及び第２側壁部７３５において変形が始まり、接続部７５と第２側壁部７３５との境界部分が盛り上がるとともに、第２車体固定部７３３が側部車体部材３１に対して浮き上がり始める（図９－２参照）。図９－３に示すように、車両の衝突が進むと前部収容空間３の前部車体部材３３が車両前後方向後方にさらに後退し、高電圧部品１をさらに後方に押し出すことがある。このとき、サイドブラケット７の変形は進み、第２側壁部７３５が大きく変形するとともに、第２車体固定部７３３が側部車体部材３１に対して浮き上がる（図９－３参照）。 As shown in FIG. 9-1, the high voltage component 1 is installed in the upper region of the power unit 4, and the high voltage component 1 is provided between the side vehicle body member 31 of the front housing space 3 and the high voltage component 1.

As shown in FIG. 9-2, when the vehicle body collides, the front vehicle body member 33 of the front storage space 3 moves rearward in the longitudinal direction of the vehicle, which may push the high-voltage component 1 rearward. At this time, the side bracket 7 starts to deform around the connecting portion 75 and the connecting portion 75 (see FIGS. 9-2 and 10-2). For example, the connecting portion 75 and the second side wall portion 735 start to deform, the boundary portion between the connecting portion 75 and the second side wall portion 735 swells, and the second vehicle body fixing portion 733 starts to rise with respect to the side vehicle body member 31 .

　上述した本発明の実施形態に係る高電圧部品１の支持構造２によれば、第１支持部と第２支持部は、車両前後方向に延びる平板状の接続部で連結されるので、車両の前突により前部車体部材３３が後退し、高電圧部品１が押されても、サイドブラケット７が平板状の接続部７５で変形する。これにより、高電圧部品１の後退（変位）をコントロールして高電圧部品１とパワーユニット４の干渉を抑制することができる。 According to the support structure 2 for the high-voltage component 1 according to the embodiment of the present invention described above, the first support portion and the second support portion are connected by the flat connecting portion extending in the longitudinal direction of the vehicle. Even if the front vehicle body member 33 retreats due to a frontal collision and the high-voltage component 1 is pushed, the side bracket 7 deforms at the flat connecting portion 75 . Thereby, it is possible to control the retraction (displacement) of the high-voltage component 1 and suppress the interference between the high-voltage component 1 and the power unit 4 .
　また、接続部７５は、第１部品固定部７１１から連続して車両後方へ延設されて第２側壁部７３５の第２部品固定部７３１より前方かつ車幅方向外側へ延びた部位の上端縁と接続されるので、車両の前突により前部車体部材３３が後退し、高電圧部品１が押されても、サイドブラケット７が接続部７５で変形する。これにより、高電圧部品１の後退（変位）をコントロールして高電圧部品１とパワーユニット４の干渉を抑制することができる。 The connection portion 75 extends rearward of the vehicle continuously from the first component fixing portion 711 and extends forward and outward in the vehicle width direction from the second component fixing portion 731 of the second side wall portion 735 . , the side bracket 7 is deformed at the connecting portion 75 even if the front vehicle body member 33 retreats due to a frontal collision of the vehicle and the high-voltage component 1 is pushed. Thereby, it is possible to control the retraction (displacement) of the high-voltage component 1 and suppress the interference between the high-voltage component 1 and the power unit 4 .
　また、第２側壁部７３５の上端縁には、接続部７５と第２部品固定部７３１との間の部位に下方に切り込まれたノッチが設けられるので、車両の前突の際に接続部７５と第２部品固定部７３１との間で大きく変形するので、高電圧部品１の後退（変位）をコントロールして高電圧部品１とパワーユニット４の干渉を抑制することができる。 In addition, the upper edge of the second side wall portion 735 is provided with a notch that is cut downward at a portion between the connecting portion 75 and the second part fixing portion 731.
