以下、本発明の実施例を図面に基づいて説明する。
図１～図３に車高が高い自動車のルーフ構造を示してある。このルーフ構造は、左右一対のルーフサイドレール１の前端部に架け渡されたルーフフロントメンバ２と、ルーフフロントメンバ２の車両後方側Ｒｒに位置するように左右一対のルーフサイドレール１に架け渡されたルーフメンバ３と、ルーフパネル４を備えている。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1 to 3 show the roof structure of an automobile having a high vehicle height. This roof structure spans the roof front member 2 spanning the front ends of the pair of left and right roof side rails 1 and the pair of left and right roof side rails 1 so as to be located on the vehicle rear side Rr of the roof front member 2. The roof member 3 and the roof panel 4 are provided.

［ルーフフロントメンバ２の構造］
図３，図５，図６に示すように、ルーフフロントメンバ２は、上側が開口した断面ハット形状に形成され、平面視で車両前方側Ｆｒに突曲する緩やかな円弧状に形成されている。そして、ルーフフロントメンバ２の前後一対の取付けフランジ２１がルーフパネル４の下面に接合されている。 [Structure of roof front member 2]
As shown in FIGS. 3, 5, and 6, the roof front member 2 is formed in a cross-sectional hat shape in which the upper side is open, and is formed in a gentle arc shape that bends toward the front side Fr of the vehicle in a plan view. .. A pair of front and rear mounting flanges 21 of the roof front member 2 are joined to the lower surface of the roof panel 4.

［ルーフメンバ３の構造］
図３，図７，図９に示すように、ルーフメンバ３は、略左右対称（車体の車幅方向の中心に対して対称）であり、上側が開口した断面ハット形状に形成されている。このルーフメンバ３は、車幅方向に長い底壁３１と、底壁３１の前端部から前上方に立ち上がる前壁３２と、底壁３１の後端部から後上方に立ち上がる後壁３３と、底壁３１の車幅方向の両端部から各別に立ち上がる左右のメンバ側壁３４，４４とを備えている。 [Structure of roof member 3]
As shown in FIGS. 3, 7, and 9, the roof member 3 is substantially symmetrical (symmetric with respect to the center in the vehicle width direction of the vehicle body), and is formed in a cross-sectional hat shape with an open upper side. The roof member 3 includes a bottom wall 31 that is long in the vehicle width direction, a front wall 32 that rises forward and upward from the front end of the bottom wall 31, a rear wall 33 that rises rearward and upward from the rear end of the bottom wall 31, and a bottom. It is provided with left and right member side walls 34 and 44 that separately rise from both ends of the wall 31 in the vehicle width direction.

そして、前壁３２の上端部から車両前方側Ｆｒに前側フランジ３２Ｆが張り出し、後壁３３の上端部から車両後方側Ｒｒに後側フランジ３３Ｆが張り出し、左右のメンバ側壁３４，４４から車幅方向外側に左側フランジ３４Ｆと右側フランジ４４Ｆが張り出している。図５に示すように、前側フランジ３２Ｆと後側フランジ３３Ｆと左側フランジ３４Ｆと右側フランジ４４Ｆはルーフパネル４の下面に接合されている。 Then, the front flange 32F projects from the upper end of the front wall 32 to the vehicle front side Fr, the rear flange 33F projects from the upper end of the rear wall 33 to the vehicle rear side Rr, and the vehicle width direction from the left and right member side walls 34 and 44. The left flange 34F and the right flange 44F project to the outside. As shown in FIG. 5, the front flange 32F, the rear flange 33F, the left flange 34F, and the right flange 44F are joined to the lower surface of the roof panel 4.

前記前壁３２には、ルーフメンバ３が外力を受けた場合に前記前壁３２を変形しやすくする複数の貫通孔３２Ｈが形成されている。これにより、外部からルーフパネル４に物体（例えば歩行者）が落下してきた場合にルーフメンバ３が容易に変形して、傷害値が軽減する。 The front wall 32 is formed with a plurality of through holes 32H that facilitate the deformation of the front wall 32 when the roof member 3 receives an external force. As a result, when an object (for example, a pedestrian) falls on the roof panel 4 from the outside, the roof member 3 is easily deformed and the injury value is reduced.

図６，図７に示すように、ルーフメンバ３の車幅方向（長手方向）の両端部に、底壁３１から下方に膨出する第１膨出部１１がそれぞれ形成されている。また、ルーフメンバ３の車幅方向の中央部と一端部との間、及び、前記中央部と他端部との間に、底壁３１から下方に膨出する第２膨出部１２がそれぞれ形成されている。さらに、ルーフメンバ３の車幅方向の中央部に、底壁３１から下方に膨出する第３膨出部１３が形成されている。 As shown in FIGS. 6 and 7, first bulging portions 11 bulging downward from the bottom wall 31 are formed at both ends of the roof member 3 in the vehicle width direction (longitudinal direction). Further, a second bulging portion 12 that bulges downward from the bottom wall 31 is provided between the central portion and one end portion of the roof member 3 in the vehicle width direction and between the central portion and the other end portion, respectively. It is formed. Further, a third bulging portion 13 that bulges downward from the bottom wall 31 is formed at the central portion of the roof member 3 in the vehicle width direction.

第１膨出部１１と第２膨出部１２と第３膨出部１３は、下方に向かって窄まる中空の四角錐台状に形成されている。第１膨出部１１と第２膨出部１２の断面形状は、車両前後方向に長い長方形状であり、第３膨出部１３の断面形状は、車幅方向に長い長方形状である。第３膨出部１３の膨出端部の端面１３Ｔには、上方に凹む凹部１５が形成されている。これにより、第３膨出部１３の剛性を向上させることができる。凹部１５は上方に向かって窄まる中空の四角錐台状に形成されている。上記のルーフメンバ３は、一枚の金属板を深絞り加工して成形されている。 The first bulging portion 11, the second bulging portion 12, and the third bulging portion 13 are formed in the shape of a hollow quadrangular pyramid that narrows downward. The cross-sectional shape of the first bulging portion 11 and the second bulging portion 12 is a rectangular shape long in the vehicle front-rear direction, and the cross-sectional shape of the third bulging portion 13 is a rectangular shape long in the vehicle width direction. A recess 15 recessed upward is formed in the end surface 13T of the bulging end portion of the third bulging portion 13. As a result, the rigidity of the third bulging portion 13 can be improved. The recess 15 is formed in the shape of a hollow quadrangular frustum that narrows upward. The roof member 3 is formed by deep drawing a single metal plate.

図４，図５に示すように、第１膨出部１１の膨出端部の端面１１Ｔと第２膨出部１２の膨出端部の端面１２Ｔとにわたって、長方形状のサンバイザ５の上端部が取り付けられている。サンバイザ５の上端部は、支持具４１を介して第１膨出部１１と第２膨出部１２に、車幅方向に沿う横軸心周りに揺動自在に支持されている。このようにして、サンバイザ５が、上下方向に沿う作用姿勢（図４，図５の右側のサンバイザ５）と、車両前後方向に沿う格納姿勢（図４，図５の左側のサンバイザ５）とに切り換え自在に構成されている。本実施例では、作用姿勢のサンバイザ５を車両後方側Ｒｒに揺動させて格納姿勢に設定し、格納姿勢のサンバイザ５を車両前方側Ｆｒに揺動させて作用姿勢に設定する。 As shown in FIGS. 4 and 5, the upper end portion of the rectangular sun visor 5 extends over the end surface 11T of the bulging end portion of the first bulging portion 11 and the end surface 12T of the bulging end portion of the second bulging portion 12. Is attached. The upper end portion of the sun visor 5 is swingably supported by the first bulging portion 11 and the second bulging portion 12 via the support tool 41 around the horizontal axis along the vehicle width direction. In this way, the sun visor 5 has a working posture along the vertical direction (sun visor 5 on the right side in FIGS. 4 and 5) and a retracted posture along the front-rear direction of the vehicle (sun visor 5 on the left side in FIGS. 4 and 5). It is configured to be switchable. In this embodiment, the sun visor 5 in the acting posture is swung to the rear side Rr of the vehicle to set the retracted posture, and the sun visor 5 in the retracted posture is swung to the front side Fr of the vehicle to set the working posture.

図７に示すように、第１膨出部１１の膨出端部の端面１１Ｔには長方形状のパッチ４３が貼着されている。これにより、高荷重が加わる第１膨出部１１の膨出端部の板厚を厚くすることができ、ルーフメンバ３の剛性を向上できながら、ルーフメンバ３を軽量化することができる。 As shown in FIG. 7, a rectangular patch 43 is attached to the end surface 11T of the bulging end portion of the first bulging portion 11. As a result, the plate thickness of the bulging end portion of the first bulging portion 11 to which a high load is applied can be increased, the rigidity of the roof member 3 can be improved, and the weight of the roof member 3 can be reduced.

また、図５，図１１に示すように、第３膨出部１３の膨出端部に形成された凹部１５の内底面１５Ｔ（図７参照）に、ルームミラー６（ミラーに相当）のアーム４５のベース部４６が取り付けられている。第３膨出部１３の膨出端部の端面１３Ｔに、上方に凹む凹部１５が形成されていることで、前記ベース部４６の取り付け用の座面（内底面１５Ｔ）を確保することができる。さらに、第４膨出部１４と合わせて、ベース部４６の取り付け用のスクリューを乗員から見えにくくすることができる。 Further, as shown in FIGS. 5 and 11, the arm of the rearview mirror 6 (corresponding to a mirror) is attached to the inner bottom surface 15T (see FIG. 7) of the recess 15 formed in the bulging end portion of the third bulging portion 13. The base portion 46 of 45 is attached. Since the concave portion 15 recessed upward is formed in the end surface 13T of the bulging end portion of the third bulging portion 13, the seat surface (inner bottom surface 15T) for mounting the base portion 46 can be secured. .. Further, together with the fourth bulging portion 14, the screw for attaching the base portion 46 can be obscured from the occupant.

図１２に示すように、第２膨出部１２の膨出端部の端面１２Ｔ（下端面、図７も参照）は、第１膨出部１１の膨出端部の端面１１Ｔよりも下方に位置し、第３膨出部１３の膨出端部の端面１３Ｔは、第２膨出部１２の膨出端部の端面１２Ｔよりも下方に位置している。また、第２膨出部１２の車幅方向の一対の側壁３７，３８のうち、ルーフメンバ３の車幅方向中央部側に位置する側壁３７の上端３７Ｔは、ルーフメンバ３の車幅方向外側に位置する側壁３８の上端３８Ｔよりも下方に位置している。 As shown in FIG. 12, the end surface 12T (lower end surface, also see FIG. 7) of the bulging end portion of the second bulging portion 12 is below the end surface 11T of the bulging end portion of the first bulging portion 11. The end surface 13T of the bulging end portion of the third bulging portion 13 is located below the end surface 12T of the bulging end portion of the second bulging portion 12. Further, of the pair of side walls 37 and 38 in the vehicle width direction of the second bulging portion 12, the upper end 37T of the side wall 37 located on the vehicle width direction center portion side of the roof member 3 is outside the vehicle width direction of the roof member 3. It is located below the upper end 38T of the side wall 38 located at.

図６，図７に示すように、第３膨出部１３を含むルーフメンバ３の車幅方向中央部に、第３膨出部１３の後部及びルーフメンバ３の後壁３３から車両後方側Ｒｒに膨出する第４膨出部１４が形成されている。第４膨出部１４は、車両後方側Ｒｒから見て下窄まりの山形状に形成されている。上側ほど車幅方向外側に位置するように傾斜している第４膨出部１４の車幅方向の側壁３９は、一部分３９Ａが第２膨出部１２の車両後方側Ｒｒに位置している。 As shown in FIGS. 6 and 7, in the vehicle width direction center portion of the roof member 3 including the third bulging portion 13, the rear portion of the third bulging portion 13 and the rear wall 33 of the roof member 3 to the vehicle rear side Rr. A fourth bulging portion 14 is formed. The fourth bulging portion 14 is formed in a mountain shape of a lower constriction when viewed from the rear side Rr of the vehicle. A part 39A of the side wall 39 in the vehicle width direction of the fourth bulging portion 14, which is inclined so as to be located on the outer side in the vehicle width direction toward the upper side, is located on the vehicle rear side Rr of the second bulging portion 12.

図１０に示すように、第４膨出部１４の膨出端部の裏側に、ルームランプ５１が取り付けられている。上記のように、ルーフメンバ３の車幅方向中央部部に第４膨出部１４が形成されていることで、ルームランプ５１の取り付けに必要な領域（面積）を確保できる。また、第４膨出部１４が周辺の形状と滑らかにつながり、剛性を確保することができる。 As shown in FIG. 10, a room lamp 51 is attached to the back side of the bulging end portion of the fourth bulging portion 14. As described above, since the fourth bulging portion 14 is formed in the central portion of the roof member 3 in the vehicle width direction, the area (area) required for mounting the room lamp 51 can be secured. Further, the fourth bulging portion 14 is smoothly connected to the surrounding shape, and rigidity can be ensured.

図６に示すように、第４膨出部１４の側壁３９の上端部に形成されたフランジ３９Ｆと、第４膨出部１４の後壁４０（他の壁部に相当）の上端部に形成されたフランジ４０Ｆとは、ルーフパネル４の下面に接合されている。 As shown in FIG. 6, the flange 39F formed at the upper end of the side wall 39 of the fourth bulge 14 and the upper end of the rear wall 40 (corresponding to another wall) of the fourth bulge 14 are formed. The flange 40F is joined to the lower surface of the roof panel 4.

本実施例の自動車のルーフ構造によれば、車高が高い自動車であっても、サンバイザ５やルームミラー６とルーフメンバ３の間に別部品を介在させる必要がなく、サンバイザ５やルームミラー６をルーフメンバ３に直接取り付けることができる。従って、部品点数を少なくできて、軽量化・製作コストの低廉化を図ることができる。 According to the roof structure of the automobile of the present embodiment, it is not necessary to interpose a separate part between the sun visor 5 and the rearview mirror 6 and the roof member 3, even if the automobile has a high vehicle height, and the sun visor 5 and the rearview mirror 6 do not need to be interposed. Can be directly attached to the roof member 3. Therefore, the number of parts can be reduced, and the weight and the manufacturing cost can be reduced.

そして、第１膨出部１１と第２膨出部１２と第３膨出部１３の下方への膨出量が、この順に徐々に大きくなっているから、ルーフメンバ３の車幅方向の側部が側端（ルーフメンバ３の車幅方向の端縁）から急激に深くなることを回避できる。その結果、ルーフメンバ３を成形加工しやすくなり、ルーフメンバ３の成形性を向上できる。また、ルーフメンバ３の車幅方向の側部が側端から急激に深くなる構造では成形加工が困難になって、ルーフメンバ３を複数に分割する必要があるが、本実施例のルーフメンバ３では、ルーフメンバ３を複数に分割しなくても済む。従って、部品点数を低減でき、ルーフメンバ３の加工の工数の増加を回避でき、製造コストを低廉化できる。 Since the downward bulging amount of the first bulging portion 11, the second bulging portion 12, and the third bulging portion 13 gradually increases in this order, the side of the roof member 3 in the vehicle width direction. It is possible to prevent the portion from suddenly deepening from the side edge (the edge of the roof member 3 in the vehicle width direction). As a result, the roof member 3 can be easily molded, and the formability of the roof member 3 can be improved. Further, in a structure in which the side portion of the roof member 3 in the vehicle width direction suddenly becomes deeper from the side end, molding processing becomes difficult, and it is necessary to divide the roof member 3 into a plurality of parts. Then, it is not necessary to divide the roof member 3 into a plurality of parts. Therefore, the number of parts can be reduced, the increase in man-hours for processing the roof member 3 can be avoided, and the manufacturing cost can be reduced.

そして、ルーフメンバ３の成形性を向上できる構造でありながら、第３膨出部１３の下方への突出量をある程度大きくすることができる。これにより、ルームミラー６やサンバイザ５等の内装部品のレイアウトを成立させることができる。また、ルーフメンバ３に、第１膨出部１１と第２膨出部１２と第３膨出部１３が形成されていることで、ルーフメンバ３の剛性を確保することができる。 The structure can improve the formability of the roof member 3, but the amount of protrusion of the third bulging portion 13 downward can be increased to some extent. As a result, the layout of interior parts such as the rearview mirror 6 and the sun visor 5 can be established. Further, since the roof member 3 is formed with the first bulging portion 11, the second bulging portion 12, and the third bulging portion 13, the rigidity of the roof member 3 can be ensured.

図７，図９，図１３に示すように、第３膨出部１３の下端部に複数の水抜き孔２５が形成されている。また、図１４，図１５に示すように、ルーフメンバ３の下方に位置するルーフライニング７の車幅方向中央部に、前記水抜き孔２５から流下する水を受け入れる幅広の溝部８が車両前後方向に沿って形成されている。溝部８は、車両前方側Ｆｒほど下方に位置するように傾斜している。さらに、平面視で、前記溝部８は左右一対の第２膨出部１２の間に位置し、車両前方側Ｆｒになるにつれて幅狭になるように形成されている。溝部８の前端部は上方に円弧状に曲がっている。 As shown in FIGS. 7, 9, and 13, a plurality of drain holes 25 are formed at the lower end of the third bulging portion 13. Further, as shown in FIGS. 14 and 15, a wide groove portion 8 for receiving water flowing down from the drain hole 25 is provided in the vehicle front-rear direction at the center portion of the roof lining 7 located below the roof member 3 in the vehicle width direction. It is formed along. The groove portion 8 is inclined so as to be located downward toward the front side Fr of the vehicle. Further, in a plan view, the groove portion 8 is located between the pair of left and right second bulging portions 12, and is formed so as to become narrower toward the front side Fr of the vehicle. The front end portion of the groove portion 8 is bent upward in an arc shape.

これにより、ルーフパネル４の車内側に結露した水のうち、ルーフメンバ３領域内で落下した分が、図１４に示すように、第３膨出部１３の下端部の水抜き孔２５からルーフライニング７に落下し、溝部８に導かれて溝部８内を車両前方側Ｆｒに向かって流れる。矢印Ｒは水の流れを示している。そして、前記水が、車幅方向外側のフロントピラー９（図１０参照）のピラートリム内を流下して車外に排出される。これにより、ルーフパネル４の車内側に結露した水を車外に円滑に排出することができる。 As a result, of the water condensed on the inside of the vehicle of the roof panel 4, the amount of water that has fallen in the roof member 3 region is removed from the drain hole 25 at the lower end of the third bulging portion 13, as shown in FIG. It falls on the lining 7, is guided by the groove 8, and flows through the groove 8 toward the front Fr of the vehicle. The arrow R indicates the flow of water. Then, the water flows down inside the pillar trim of the front pillar 9 (see FIG. 10) outside in the vehicle width direction and is discharged to the outside of the vehicle. As a result, the water condensed on the inside of the roof panel 4 can be smoothly discharged to the outside of the vehicle.

また、前述のように、ルーフメンバ３の車幅方向中央部側に位置する第２膨出部１２の側壁３７の上端３７Ｔが、車幅方向外側に位置する第２膨出部１２の側壁３８の上端３８Ｔよりも下方に位置するから、第２膨出部１２内の水を水抜き孔２５側に流しやすくなる。 Further, as described above, the upper end 37T of the side wall 37 of the second bulging portion 12 located on the vehicle width direction center side of the roof member 3 is the side wall 38 of the second bulging portion 12 located outside the vehicle width direction. Since it is located below the upper end 38T of the swelling portion 12, the water in the second bulging portion 12 can easily flow to the drain hole 25 side.
