【発明の詳細な説明】
この発明は自動車等の車体閉断面の閉塞方法の
改良に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a method for closing a closed section of a vehicle body such as an automobile.
自動車等においては、その車体のピラー部等
に、多くの中空の閉断面部分があり、一般的に自
動車等の空調性能を確保するためにこれら閉断面
を構成するパネルの一部に空気排出口を設け、空
気の流通が促進されるようにしている。 In automobiles, there are many hollow closed cross-section parts in the pillars of the car body, and in order to ensure the air conditioning performance of automobiles, air exhaust ports are generally installed in some of the panels that make up these closed cross-sections. are installed to promote air circulation.
また、車体の塗装工程において、特に電着塗装
時における電着液を閉断面内に流す必要性から、
閉断面に開口が形成されている。 In addition, in the car body painting process, especially during electrodeposition painting, it is necessary to flow the electrodeposition liquid within a closed cross section.
An opening is formed in the closed cross section.
従つて、従来は、前記排出口に至る室内の通常
の空気排出ルートの他に、前記開口から閉断面内
を流れる空気の流通ルートが形成され、これが、
車室内騒音を増大させるという問題点があつた。 Therefore, conventionally, in addition to the normal indoor air exhaust route leading to the exhaust port, a circulation route for air flowing from the opening in a closed cross section is formed, and this is
There was a problem in that it increased the noise inside the vehicle.
この対策として、予め閉断面を所要固所で閉塞
させることも考えられるが、これは、電着塗装の
際における電着液の閉断面内への流れを妨げ、従
つて、車体の防錆性能および塗装品質の低下を来
たすことになるという新たな問題点を生じる。 As a countermeasure to this problem, it is possible to block the closed cross section at a required fixed point in advance, but this will impede the flow of the electrodeposition liquid into the closed cross section during electrodeposition painting, and will therefore reduce the rust prevention performance of the car body. A new problem arises in that the coating quality also deteriorates.
従つて、従来は、前記騒音を抑制するために、
車体塗装後、車室内の内装工程時に、シート状部
材によつて前記開口等を覆つていたが、騒音抑制
が不充分であるとともにコストがかかるという問
題点があつた。 Therefore, conventionally, in order to suppress the noise,
After the vehicle body is painted, the openings and the like are covered with a sheet-like member during the process of interior decoration of the vehicle interior, but there are problems in that noise suppression is insufficient and costs are high.
この発明は上記従来の問題点に鑑みてなされた
ものであつて、簡単かつ安価な手段により、電着
塗装液の閉断面内の流れを妨げることなく車体閉
断面を閉塞することができる方法を提供すること
を目的とする。 The present invention has been made in view of the above-mentioned conventional problems, and provides a method for closing a closed cross section of a vehicle body by a simple and inexpensive means without interfering with the flow of electrocoating liquid within the closed cross section. The purpose is to provide.

ある。 This invention reduces the cross-sectional area of a closed cross-section member of a vehicle body in part to form a reduced section, and in a step before a painting process, the closed cross-section member of the vehicle body is placed above the reduced section of the closed section member of the vehicle body. arranging an unfoamed foam material that is smaller than the cross section and capable of locking in the reduced portion, and heating and foaming the foam material using a heat source in the paint drying process to close the closed cross section member of the vehicle body; This achieves the above objective.
以下本発明に係る車体閉断面の閉塞方法の実施
例を図面を参照して説明する。 Embodiments of the method for closing a closed section of a vehicle body according to the present invention will be described below with reference to the drawings.

ものである。 In this embodiment, as shown in FIGS. 1 to 3, in the pre-painting process, unfoamed foam smaller than the closed cross section 2 is formed at required fixed points within the closed cross section 2 of the vehicle body 1. The foamed material 3 is placed and heated and foamed by a heat source in the paint drying process to close the closed cross section 2 of the vehicle body 1.
前記車体１の閉断面２の断面積は、一部におい
て、前記未発泡状態の発泡材３よりも小さく縮小
され、第３図に示されるように、該縮小部４の上

る。 Of the inner panel 2A and outer panel 2B, which are cross-sectional members constituting the closed cross section 2, the reduced portion 4 is attached to the inner panel 2A on the inner panel 2A side.
It is formed at the same time as press molding.

れる。 Further, the unfoamed foam material 3 is attached to the inside of the inner panel 2A at a position above the reduced portion 4, before the inner panel 2A and the outer panel 2B are welded at both ends to form the closed cross section 2. To place something. In this case, if the foaming agent 3 is a molded sealer, the adhesive force of the sealer itself will adhere.

インナパネル２Ａの内側面からはがれても、縮小
部４部分における閉断面２の断面積が未発泡状態
の発泡材３よりも小さいので、該発泡材３が閉断
面２内から流出するようなことはない。 When painting a car body 1 having a closed cross section 2 with an unfoamed foam material 3 disposed inside, for example, when performing electrodeposition coating, the electrodeposition liquid is flowed inside the closed cross section 2, but the unfoamed foam material 3 is Since the foamed material 3 in the state is smaller than the cross-sectional area of the closed cross section 2, it does not obstruct the flow of the electrodeposition liquid. Furthermore, even if the foaming agent 3 is peeled off from the inner surface of the inner panel 2A while the electrodeposition liquid is flowing down, the cross-sectional area of the closed section 2 at the reduced portion 4 is smaller than that of the foamed material 3 in an unfoamed state. The foamed material 3 will not flow out from inside the closed section 2.

手方向の全範囲に亘つて閉塞するものでない。 In the final stage of the painting process, the car body 1 is heated and dried in a paint drying oven. At this time, the unfoamed foam material 3 expands due to the heat used to dry the paint, completely blocking the closed section 2. do. Here, the closing only needs to be to close the closed cross section 2 at at least one fixed point in the longitudinal direction of the closed cross section member consisting of the inner panel 2A and the outer panel 2B, and not to close the entire range in the longitudinal direction.
従つて、塗装工程の完了後に新たな作業を伴う
ことなく閉断面２を完全に閉塞できる。 Therefore, the closed section 2 can be completely closed off without any new work after the painting process is completed.

されるものでない。 In the above embodiment, the reduced portion 4 is formed in the closed cross section 2 as a means to prevent the unfoamed foam material 3 from being washed away by the electrodeposition liquid.
This may be any structure as long as the unfoamed foam material 3 is locked in the reduced portion 4 and the foam material 3 is substantially prevented from flowing out due to the electrodeposited liquid, and is not limited to the configuration of the embodiment. Not.
