JP 2004-82885 A (Page 9, FIG. 1)

特許文献１を次図に基づいて説明する。
図６は、従来の技術の基本構成を説明する図であり、従来の自動車車体の上側部構造は、ルーフサイドレール１０１が、レールアウタパネル１０２と、レールインナパネル１０３と、これら両パネル１０２、１０３の間に介設されたレール補強パネル１０４と、を備え、これらのパネル１０２、１０３、１０４の端部をスポット溶接（溶接部１０５、１０６）すると、ピラーにシートベルトによる引っ張り力が加わっても、レール補強パネル１０４によって、ルーフサイドレール１０１のスポット溶接した溶接部は、容易に破断しないというものである。 Patent document 1 is demonstrated based on the following figure.
FIG. 6 is a diagram for explaining the basic configuration of the conventional technique. The upper side structure of a conventional automobile body is composed of a roof side rail 101, a rail outer panel 102, a rail inner panel 103, and both the panels 102, 103. Rail reinforcement panel 104 interposed between them, and spot welding (welding portions 105, 106) of the end portions of these panels 102, 103, 104, even if a pulling force by a seat belt is applied to the pillar The welded portion of the roof side rail 101 spot welded by the rail reinforcing panel 104 is not easily broken.

しかし、特許文献１の自動車車体の上側部構造では、パネル１０２、１０３、１０４の端部をスポット溶接するために、レールアウタパネル１０２とレールインナパネル１０３とでレール補強パネル１０４を挟む際に、レール補強パネル１０４の位置がずれることがある。例えば、図の左を下にした状態、つまりレールアウタパネル１０２を一体に成形したアウタパネルを置き、ほぼ垂直となるレールアウタパネル１０２にレール補強パネル１０４を矢印ａ１のように重ね、重ねたレール補強パネル１０４にレールインナパネル１０３をさらに矢印ａ２のように重ねると、レール補強パネル１０４の端部１０７が矢印ａ３の方向にずれて、レール補強パネル１０４が二点鎖線で示すような状態になることが考えられる。   However, in the upper side structure of the automobile body of Patent Document 1, when the rail reinforcing panel 104 is sandwiched between the rail outer panel 102 and the rail inner panel 103 in order to spot weld the end portions of the panels 102, 103, 104, the rail The position of the reinforcing panel 104 may shift. For example, a state in which the left side of the figure is turned down, that is, an outer panel in which the rail outer panel 102 is integrally formed is placed, and the rail reinforcing panel 104 is overlapped on the rail outer panel 102 that is almost vertical as shown by the arrow a1, and the rail reinforcing panel 104 overlapped. If the rail inner panel 103 is further overlapped as shown by an arrow a2, the end 107 of the rail reinforcing panel 104 is displaced in the direction of the arrow a3, and the rail reinforcing panel 104 is in a state indicated by a two-dot chain line. It is done.

（ｃ）において、重ねたルーフレール補強部材５４Ｂの当接折り曲げ部７３にルーフレールインナ部５１の第１折り曲げ部８１を重ね、ルーフレール補強部材５４Ｂの接触折り曲げ部７４にルーフレールインナ部５１の第２折り曲げ部８２を重ねるとともに、矢印ｂ４，ｂ５のように押して重ねた折り曲げ部７１〜７４，８１，８２同士を密着させる。   In (c), the first bent portion 81 of the roof rail inner portion 51 is overlapped with the contact bent portion 73 of the overlapped roof rail reinforcing member 54B, and the second bent portion of the roof rail inner portion 51 is overlapped with the contact bent portion 74 of the roof rail reinforcing member 54B. 82 are overlapped, and the bent portions 71 to 74, 81, 82 are pressed and adhered as shown by arrows b4 and b5.

ルーフレールインナ部５１を矢印ｂ４，ｂ５のようにルーフレールアウタ部３５Ｂ側へ押すと、ルーフレールインナ部５１の他方の端部６６はルーフレール補強部材５４Ｂの他方の端部６４を下方（矢印ｂ６の方向）へ押すので、掛止爪７５，７５は直交折り曲げ部７２に矢印ｂ７のように当接して掛かり、ルーフレール補強部材５４Ｂの端部６４の下方への滑りを防ぐことができる。
つまり、ルーフサイドレール２９とクオーターピラー（ピラー）３１とが交差するルーフサイドレール２９内にルーフレール補強部材５４Ｂを組付ける際に、ルーフレール補強部材５４Ｂ（第２成形板材５４）のずれを防止することができる。 When the roof rail inner portion 51 is pushed toward the roof rail outer portion 35B as indicated by arrows b4 and b5, the other end portion 66 of the roof rail inner portion 51 moves down the other end portion 64 of the roof rail reinforcing member 54B (in the direction of arrow b6). Therefore, the latching pawls 75 and 75 are brought into contact with the orthogonal bent portion 72 as shown by an arrow b7, and can prevent the end portion 64 of the roof rail reinforcing member 54B from sliding downward.
That is, when the roof rail reinforcing member 54B is assembled in the roof side rail 29 where the roof side rail 29 and the quarter pillar (pillar) 31 intersect, the roof rail reinforcing member 54B (second molded plate material 54) is prevented from being displaced. Can do.

また、ルーフレールインナ部５１を矢印ｂ４，ｂ５のようにルーフレールアウタ部３５Ｂ側へ押すと、ルーフレールインナ部５１の端部６６はルーフレール補強部材５４Ｂの端部６４を下方（矢印ｂ６の方向）へ押すので、掛止爪７５，７５は直交折り曲げ部７２に当接して掛かり、ルーフレール補強部材５４Ｂの端部６４（接触折り曲げ部７４）の下方への滑りを防ぐことができる。従って、交差部３２の組付けは容易になる。   When the roof rail inner portion 51 is pushed toward the roof rail outer portion 35B as indicated by arrows b4 and b5, the end portion 66 of the roof rail inner portion 51 pushes the end portion 64 of the roof rail reinforcing member 54B downward (in the direction of arrow b6). Therefore, the latching pawls 75 and 75 are brought into contact with the orthogonal bent portion 72 and can be prevented from slipping downward of the end portion 64 (contact bent portion 74) of the roof rail reinforcing member 54B. Therefore, the assembly of the intersection 32 is facilitated.

図５は、本発明のフレーム構造の製造に用いるスポット溶接を実施するときの作用を説明する図である。
ルーフレールインナ部５１を重ねた後、重ねた折り曲げ部７１〜７４，８１，８２同士をスポット溶接装置８５で溶接する。その際、掛止爪７５，７５によってルーフレール補強部材５４Ｂは止めた状態となるから、交差部３２の組付け精度の管理は容易になる。 FIG. 5 is a diagram for explaining the operation when performing spot welding used for manufacturing the frame structure of the present invention.
After the roof rail inner portion 51 is overlapped, the overlapped bent portions 71 to 74, 81, 82 are welded together by the spot welding device 85. At this time, since the roof rail reinforcing member 54B is stopped by the hooking claws 75, 75, the assembly accuracy of the intersecting portion 32 can be easily managed.

尚、本発明の車両のフレーム構造は、実施の形態ではルーフサイドレールとピラーとが交差する交差部に採用したが、交差部の無い閉断面形状のレール構造に採用することは差し支えない。   In the embodiment, the vehicle frame structure of the present invention is employed at the intersection where the roof side rail and the pillar intersect. However, the vehicle frame structure may be employed in a rail structure having a closed cross section without the intersection.

本発明の車両のフレーム構造は、ルーフサイドレールとピラーとが交差する交差部に好適である。   The frame structure of the vehicle of the present invention is suitable for an intersection where the roof side rail and the pillar intersect.
