Abstract

In an automobile roof structure, a reinforcement member is joined as a separate part to enhance surface rigidity of a roof panel. Conventionally, a reinforcement member has been used as a separate part resulting in an additional part and higher cost. The present invention aims at reducing the production cost of the roof structure. A roof panel (11) is divided into a front panel (12) and a rear panel (13). The front panel (12) has an upward projection (12a) with a downward recess along the rear end thereof while the rear panel (13) has a downward projection (13a) with an upward recess along the front end thereof. The upward projection (12a) and the downward projection are superposed on each other creating a hollow closed profile therebetween extending in the direction of breadth which serves as a reinforcement member (R/F).

Description

自動車のルーフ構造Automobile roof structure
　本発明は、自動車のルーフ構造に関する。 The present invention relates to an automobile roof structure.
　自動車のルーフは、ルーフパネルの車室内側を複数のリインホースメント（補強部材）で補強してその面剛性を高めた構成を備えている。各リインホースメントは、ルーフパネルの車室内側に沿って左右のルーフサイドレール間に跨った状態に結合されている。
　通常、リインホースメントは、ルーフパネルの車幅方向ほぼ全長にわたる長さの帯鋼板を断面コ字形にプレス成形したもので、図４に示すように車室内側（下向き）に凸となる向きでルーフパネルＲの内面にスポット溶接あるいはマスチックシーラＭ等の接着手段を用いて結合される。このリインホースメントＲ／ＦとルーフパネルＲとで閉じ断面形状部が構成されることによって当該ルーフパネルＲの面剛性が高められる。
　係るルーフパネルＲのリインホースメントＲ／Ｆに関する技術が、従来例えば下記の特許文献等に記載されている。これら特許文献等に記載されているように従来リインホースメントＲ／Ｆは、ルーフパネルＲとは別部品としてプレス成形により製作したものを上記の手段によりルーフパネルＲに結合する構成となっていた。 The roof of an automobile has a configuration in which the interior side of the roof panel is reinforced with a plurality of reinforcements (reinforcing members) to increase the surface rigidity. Each reinforcement is coupled in a state straddling between the left and right roof side rails along the vehicle interior side of the roof panel.
In general, reinforcement is formed by pressing a strip steel plate having a length that covers almost the entire length of the roof panel in the vehicle width direction into a U-shaped cross section. As shown in FIG. Bonded to the inner surface of the roof panel R using spot welding or mastic sealer M or the like. The reinforcement R / F and the roof panel R constitute a closed cross-section so that the surface rigidity of the roof panel R is enhanced.
Techniques relating to the reinforcement R / F of the roof panel R have been conventionally described in, for example, the following patent documents. As described in these patent documents and the like, the conventional reinforcement R / F has a structure in which what is manufactured by press molding as a separate part from the roof panel R is coupled to the roof panel R by the above-described means. .

　このように従来ルーフパネルＲのリインホースメントＲ／Ｆは、ルーフパネルＲとは別に製作するプレス部品であったので、その分だけ部品点数が多くなって、ルーフ構造のコスト低減を図ることが困難であった。
　本発明は、係る従来の問題に鑑みなされたもので、ルーフ構造にコスト低減を図ることを目的とする。 Thus, since the reinforcement R / F of the conventional roof panel R is a press part manufactured separately from the roof panel R, the number of parts is increased by that amount, and the cost of the roof structure can be reduced. It was difficult.
The present invention has been made in view of the conventional problems, and an object thereof is to reduce the cost of the roof structure.
　このため、本発明は特許請求の範囲に記載した構成のルーフ構造とした。
　請求項１記載のルーフ構造によれば、ルーフパネルのリインホースメントが、凸断面形状部と横断面形状部が相互に突き合わされて形成される。凸断面形状部と横断面形状部は、自動車の前後方向に少なくとも二分された前側の分割ルーフと後ろ側の分割ルーフにそれぞれのプレス成形時に同時かつ一体にプレス成形されて設けられる。このため、従来のようにリインホースメントを別工程で製作する必要はないので、部品点数及び組み立て工数の低減を図ることでき、ひいては当該ルーフ構造のコスト低減を図ることができる。
　請求項２記載のルーフ構造によれば、自動車の前後方向に沿ったリインホースメントを構成する凸断面形状部と凹断面形状部がそれぞれ分割ルーフパネルに一体成形されていることから、従来のような別部品としてのリインホースメントを省略して当該ルーフ構造の低コスト化を図ることができる。 For this reason, the present invention has a roof structure configured as described in the claims.
According to the roof structure of the first aspect, the reinforcement of the roof panel is formed by causing the convex cross-sectional shape portion and the cross-sectional shape portion to abut each other. The convex cross-sectional shape portion and the transverse cross-sectional shape portion are provided by being simultaneously press-molded simultaneously and integrally with each of the front split roof and the rear split roof that are at least bisected in the longitudinal direction of the automobile. For this reason, since it is not necessary to manufacture the reinforcement in a separate process as in the prior art, the number of parts and the number of assembly steps can be reduced, and the cost of the roof structure can be reduced.
According to the roof structure of the second aspect, since the convex cross-sectional shape portion and the concave cross-sectional shape portion constituting the reinforcement along the front-rear direction of the automobile are each integrally formed on the split roof panel, Therefore, it is possible to reduce the cost of the roof structure by omitting the reinforcement as a separate part.

　次に、本発明の実施形態を図１及び図２に基づいて説明する。図１は、第１実施形態に係るルーフ構造１０を備えた自動車のルーフＲが示されている。なお、図において左側が自動車の前側であり、右側が自動車の後ろ側となる。以下の説明では自動車の前後方向を基準として部材若しくは構成の方向を特定する。
　ルーフＲは、ルーフパネル１１とその面剛性を高めるためのリインホースメントＲ／Ｆを備えている。ルーフパネル１１は、自動車の前後方向（図１では左右方向）に２分割されている。前側の分割ルーフ１２の後端縁と後ろ側の分割ルーフ１３の前端縁が相互に結合されて一つのルーフパネル１１を構成している。
　前側の分割ルーフ１２の後端縁には、凸断面形状部１２ａが設けられている。この凸断面形状部１２ａは、上向きに凸で下向きに開口する断面形状を有しており、当該分割ルーフ１２の車幅方向のほぼ全幅にわたって設けられている。この凸断面形状部１２ａは、当該分割ルーフ１２のプレス成形によって同時かつ一体に成形される。
　後ろ側の分割ルーフ１３の前端縁には、凹断面形状部１３ａが設けられている。この凹断面形状部１３ａは、下向きに凸で上向きに開口する断面形状を有しており、当該分割ルーフ１３の車幅方向のほぼ全幅にわたって設けられている。この凹断面形状部１３ａも、当該分割ルーフ１３のプレス成形によって同時かつ一体に成形される。
　前側の分割ルーフ１２の凸断面形状部１２ａと後ろ側の分割ルーフ１３の凹断面形状部１３ａが相互の開口側を対向させた状態で接合されて、当該前側の分割ルーフ１２と後ろ側の分割ルーフ１３が結合されている。前後の分割ルーフ１２，１３が結合されて形成されたルーフパネル１１は、凸断面形状部１２ａと凹断面形状部１３ａとで形成される閉じ断面形状部がリインホースメントＲ／Ｆとして機能することによりその面剛性が確保されている。
　前側分割ルーフ１２の凸断面形状部１２ａと後ろ側分割ルーフ１３の凹断面形状部１３ａは、スポット溶接Ｓ又はマスチックシーラＭによって相互に結合されている。図１には、凸断面形状部１２ａと凹断面形状部１３ａの前側がマスチックシーラＭで接合され、後ろ側がスポット溶接Ｓによって結合された実施形態が示されている。また、図２には、凸断面形状部１２ａと凹断面形状部１３ａの前側と後ろ側の双方がスポット溶接Ｓで結合された実施形態が示されている。 Next, an embodiment of the present invention will be described with reference to FIGS. FIG. 1 shows a roof R of an automobile provided with a roof structure 10 according to the first embodiment. In the figure, the left side is the front side of the automobile, and the right side is the rear side of the automobile. In the following description, the direction of a member or a structure is specified on the basis of the front-back direction of a motor vehicle.
The roof R includes a roof panel 11 and a reinforcement R / F for increasing the surface rigidity thereof. The roof panel 11 is divided into two in the front-rear direction of the automobile (left-right direction in FIG. 1). The rear end edge of the front split roof 12 and the front end edge of the rear split roof 13 are joined together to form one roof panel 11.
A convex cross-sectional shape portion 12 a is provided at the rear end edge of the front split roof 12. The convex cross-sectional shape portion 12a has a cross-sectional shape that protrudes upward and opens downward, and is provided over substantially the entire width of the divided roof 12 in the vehicle width direction. The convex cross-sectional shape portion 12a is simultaneously and integrally formed by press molding of the divided roof 12.
A concave cross-section 13 a is provided at the front edge of the rear split roof 13. The concave cross-sectional shape portion 13a has a cross-sectional shape that protrudes downward and opens upward, and is provided over substantially the entire width of the divided roof 13 in the vehicle width direction. The concave cross-sectional shape portion 13a is also simultaneously and integrally formed by press molding of the divided roof 13.
The convex sectional shape portion 12a of the front divided roof 12 and the concave sectional shape portion 13a of the rear divided roof 13 are joined with their opening sides facing each other, so that the front divided roof 12 and the rear divided portion are separated. The roof 13 is joined. The roof panel 11 formed by combining the front and rear divided roofs 12 and 13 has a closed cross-sectional shape portion formed of a convex cross-sectional shape portion 12a and a concave cross-sectional shape portion 13a that functions as a reinforcement R / F. Therefore, the surface rigidity is ensured.
The convex sectional shape portion 12a of the front divided roof 12 and the concave sectional shape portion 13a of the rear divided roof 13 are coupled to each other by spot welding S or mastic sealer M. FIG. 1 shows an embodiment in which the front side of the convex cross-sectional shape part 12a and the concave cross-sectional shape part 13a are joined by a mastic sealer M and the rear side is joined by spot welding S. Moreover, FIG. 2 shows an embodiment in which both the front side and the rear side of the convex cross-sectional shape portion 12a and the concave cross-sectional shape portion 13a are joined by spot welding S.
　以上のように構成したルーフ構造１０によれば、ルーフパネル１１が前後に二分され、前側分割ルーフ１２の凸断面形状部１２ａと後ろ側分割ルーフ１３の凹断面形状部１３ａとが相互に結合されて、リインホースメントＲ／Ｆが形成される。このため、従来のようにルーフパネルとは別部品としてリインホースメントをプレス成形する必要がないため、部品点数の削減を図ることができる。
　また、図２に示すように凸断面形状部１２ａと凹断面形状部１３ａの結合をスポット溶接Ｓによることにより、マスチックシーラＭの塗布量を図１に示す結合形態よりも低減することができることから、マスチックシーラＭについてのコスト低減を図ることができる。 According to the roof structure 10 configured as described above, the roof panel 11 is divided into front and rear, and the convex sectional shape portion 12a of the front divided roof 12 and the concave sectional shape portion 13a of the rear divided roof 13 are coupled to each other. Thus, reinforcement R / F is formed. For this reason, since it is not necessary to press-mold the reinforcement as a separate part from the roof panel as in the prior art, the number of parts can be reduced.
Also, as shown in FIG. 2, by applying spot welding S to connect the convex cross-sectional shape portion 12a and the concave cross-sectional shape portion 13a, the application amount of the mastic sealer M can be reduced as compared with the connection configuration shown in FIG. The cost of the mastic sealer M can be reduced.
　図３には、関連する発明の実施形態が示されている。この第２実施形態に係るルーフ構造２０では、ルーフパネル２１とは別部品としてプレス成形により製作した部材を用いてリインホースメント２２を構成している。
　第２実施形態では、ルーフパネル２１は第１実施形態とは異なって前後に二分されておらず、一枚の素材をプレス成形したものが用いられている。このルーフパネル２１の前後方向ほぼ中央には、上向きに凸で下向きに開口する凸断面形状部２１ａが設けられている。この凸断面形状部２１ａは、車幅方向ほぼ全幅にわたって設けられている。この凸断面形状部２１ａの開口側（下側）に、下向きに凸で上向きに開口する凹断面形状を有する凹断面形状部材２２が相互の開口側を対向させて結合されている。図示するようにこの凹断面形状部材２２は、マスチックシーラＭを用いてルーフパネル２１の下面側に結合されている。
　この第２実施形態では、ルーフパネル２１の凸断面形状部２１ａと凹断面形状部材２２とによって閉じ断面形状部が形成されている。この閉じ断面形状部がルーフパネル２１のリインホースメントＲ／Ｆとして機能する。
　このように構成した第２実施形態によれば、ルーフパネル２１の凸断面形状部２１ａと、凹断面形状部材２２とが相互に結合されて、ルーフパネル２１のリインホースメントＲ／Ｆが構成される。このため、ルーフパネル２１の凸断面形状部２１ａと凹断面形状部材２２の双方によって閉じ断面積（断面の縦寸法ａ）を確保することができる。このことから、凹断面形状部材２２の成形深さを従来のａ寸法（図３参照）に比して大幅（例えば、半分程度）に小さなｂ寸法に設定することができる。この点、従来別部品としてのリインホースメントＲ／Ｆのみによって十分な閉じ断面積を確保するために、当該リインホースメントＲ／Ｆの成形深さを寸法ａの深さでプレス成形する必要があり、その結果、大きな幅寸法の素材を用意する必要があり、この点でコスト高となっていた。
　第２実施形態のルーフ構造２０によれば、ルーフパネル２１の凸断面形状部２１ａ及び凹断面形状部２２について、上記成形深さａ寸法よりも大幅に小さな寸法ｂでプレス成形すれば足りることから、凹断面形状部２２の素材についてより幅の小さなものを用いることによって大きなコストダウンを図ることができる。 FIG. 3 shows a related embodiment of the invention. In the roof structure 20 according to the second embodiment, the reinforcement 22 is configured using a member manufactured by press molding as a separate part from the roof panel 21.
In the second embodiment, unlike the first embodiment, the roof panel 21 is not divided into two parts in the front-rear direction, and a single material is press-formed. A convex cross-sectional shape portion 21a that protrudes upward and opens downward is provided at substantially the center of the roof panel 21 in the front-rear direction. The convex cross-sectional shape portion 21a is provided over substantially the entire width in the vehicle width direction. A concave cross-sectional shape member 22 having a concave cross-sectional shape that protrudes downward and opens upward is coupled to the opening side (lower side) of the convex cross-sectional shape portion 21a with the opening sides facing each other. As shown in the figure, the concave cross-sectional shape member 22 is coupled to the lower surface side of the roof panel 21 using a mastic sealer M.
In the second embodiment, a closed cross-sectional shape portion is formed by the convex cross-sectional shape portion 21 a and the concave cross-sectional shape member 22 of the roof panel 21. This closed cross-sectional shape portion functions as a reinforcement R / F for the roof panel 21.
According to the second embodiment configured as described above, the convex cross-sectional shape portion 21a of the roof panel 21 and the concave cross-sectional shape member 22 are coupled to each other to form the reinforcement R / F of the roof panel 21. The For this reason, the closed cross-sectional area (vertical dimension a of the cross section) can be ensured by both the convex cross-sectional shape portion 21 a and the concave cross-sectional shape member 22 of the roof panel 21. From this, the molding depth of the concave cross-sectional shape member 22 can be set to a dimension b which is significantly smaller (for example, about half) than the conventional dimension a (see FIG. 3). In this respect, in order to ensure a sufficient closed cross-sectional area only by the reinforcement R / F as a separate part in the past, it is necessary to press-mold the reinforcement R / F at a depth of the dimension a. As a result, it is necessary to prepare a material having a large width dimension, which is expensive in this respect.
According to the roof structure 20 of the second embodiment, the convex cross-sectional shape portion 21a and the concave cross-sectional shape portion 22 of the roof panel 21 need only be press-molded with a dimension b that is significantly smaller than the molding depth a dimension. A large cost reduction can be achieved by using a material having a smaller width for the material of the concave cross-section portion 22.
　以上説明した実施形態には種々変更を加えることができる。例えば、第１実施形態において、凸断面形状部１２ａと凹断面形状部１３ａとの結合についてスポット溶接ＳとマスチックシーラＭを併用する構成、スポット溶接Ｓのみにより結合する構成を例示したが、マスチックシーラＭのみによって結合する構成としてもよい。
　また、ルーフパネル１１を自動車の前後方向に二分する構成を例示したが３つ以上に分割してそれぞれ相互間に凸断面形状部と凹断面形状部を結合して複数のリインホースメントＲ／Ｆを設ける構成としてもよい。
　さらに、車幅方向（左右方向）に掛け渡してルーフパネルを補強する車幅方向のリインホースメントについて適用した構成を例示したが、ルーフパネルの前後方向に沿って設けることによりその面剛性を高めるリインホースメントに適用することもできる。この場合は、ルーフパネルを車幅方向に少なくとも２分して、左右に隣接する分割ルーフパネルの一方の端縁に凸断面形状部を一体成形し、他方の端縁に凹断面形状部を一体成形して、両断面形状部を相互に結合して形成される閉じ断面形状部を前後方向のリインホースメントＲ／Ｆとして機能させる構成とすることができる。 Various modifications can be made to the embodiment described above. For example, in the first embodiment, the configuration using the spot welding S and the mastic sealer M in combination with the convex cross-sectional shape portion 12a and the concave cross-sectional shape portion 13a, and the configuration using only the spot welding S are illustrated. It is good also as a structure couple | bonded only by M.
Moreover, although the structure which divides the roof panel 11 into the front-back direction of a motor vehicle was illustrated, it divides | segments into 3 or more, and couple | bonds a convex cross-sectional shape part and a concave cross-sectional shape part between each, and several reinforcement R / F It is good also as a structure which provides.
Furthermore, the configuration applied to the reinforcement in the vehicle width direction that reinforces the roof panel by spanning in the vehicle width direction (left and right direction) is exemplified, but the surface rigidity is increased by providing along the front and rear direction of the roof panel. It can also be applied to reinforcement. In this case, the roof panel is divided into at least two parts in the vehicle width direction, and the convex cross-sectional shape portion is integrally formed on one end edge of the split roof panel adjacent to the left and right, and the concave cross-sectional shape portion is integrated on the other end edge The closed cross-sectional shape portion formed by molding and joining both cross-sectional shape portions to each other can be configured to function as a reinforcement R / F in the front-rear direction.
