Description

本発明は、樹脂部材の接合方法及びその接合構造に関し、特に第１樹脂部材のスリット孔に第２樹脂部材の接合片を挿入して第２樹脂部材を第１樹脂部材に組付ける際に生じる位置ズレを防止し、第１，第２樹脂部材間の相対位置を適切に保持できるようにしたものに関する。   The present invention relates to a resin member joining method and a joining structure thereof, and particularly occurs when a joining piece of a second resin member is inserted into a slit hole of the first resin member and the second resin member is assembled to the first resin member. The present invention relates to a device that prevents misalignment and can appropriately maintain the relative position between the first and second resin members.

従来、自動車において、樹脂部材に金属部材を締結する場合、タッピングスクリューやボルト等で締結されるが、熱可塑性を有する樹脂部材の比較的低温で溶融し常温で冷却固化する性質を利用して、樹脂部材を熱によってかしめる接合方法が周知である。   Conventionally, when a metal member is fastened to a resin member in an automobile, it is fastened with a tapping screw, a bolt, or the like, but utilizing the property that a resin member having thermoplasticity is melted at a relatively low temperature and cooled and solidified at room temperature, A joining method in which a resin member is caulked by heat is well known.

特許文献１に記載の熱かしめ構造体及び熱かしめ接合方法には、鉄板のスリット穴に熱可塑性樹脂部材のかしめ突起を挿入した後、超音波加熱器でかしめ突起の先端側を加熱しながら加圧することで、鉄板に熱可塑性樹脂部材を溶着する技術が開示されている。
このように、異なる材質からなる部材を溶着すると、リサイクル時に鉄板と樹脂部材とを切断しなければならず、リサイクル性が低下する。リサイクル性を高める為には同じ材質の部材同士を溶着した方が望ましく、樹脂部材同士を溶着する接合方法として、第１樹脂部材のスリット孔に第２樹脂部材の接合片を挿入して接合片を第１樹脂部材に溶着する樹脂部材の接合方法が採用されている。
特開２００４−５８３９１号公報 In the heat caulking structure and the heat caulking joining method described in Patent Document 1, after inserting the caulking protrusion of the thermoplastic resin member into the slit hole of the iron plate, heating is performed while heating the front end side of the caulking protrusion with an ultrasonic heater. A technique for welding a thermoplastic resin member to an iron plate by pressing is disclosed.
Thus, if a member made of a different material is welded, the iron plate and the resin member must be cut at the time of recycling, and the recyclability decreases. In order to improve recyclability, it is desirable to weld members of the same material. As a joining method for welding resin members, a joining piece of a second resin member is inserted into a slit hole of the first resin member. A resin member joining method is employed in which the resin member is welded to the first resin member.

ところで、バンパーフェース（第１樹脂部材）にオーバーフェンダー（第２樹脂部材）を接合する場合、バンパーフェースのスリット孔にオーバーフェンダーの接合片を挿入して接合片を溶着すると、バンパーフェースに対するオーバーフェンダーの組付け時にスリット孔と接合片との間で位置ズレが生じやすく、バンパーフェースとオーバーフェンダーとの相対位置を均一に保持することは困難である。それ故、バンパーフェースとオーバーフェンダーとの接合品質が低下する虞がある。   By the way, when the over fender (second resin member) is joined to the bumper face (first resin member), the over fender with respect to the bumper face is welded by inserting the joint piece of the over fender into the slit hole of the bumper face and welding the joint piece. During the assembly, positional displacement is likely to occur between the slit hole and the joining piece, and it is difficult to keep the relative position of the bumper face and the over fender uniform. Therefore, the bonding quality between the bumper face and the over fender may be deteriorated.

Bolts 25 to 27 are inserted into the bolt holes 32 of the concave portions 22 to 24, respectively. The over fender 20 is fixed to the bumper face 1 and the vehicle body. A bolt hole 28 for bolting to the rear end of the bumper face 1 is formed in the upper end portion of the rear wall portion 20b, and the rear portion of the over fender 20 is bolted to the bumper face 1 and the vehicle body. A mudguard 4 is attached to the front surface of the right end portion of the rear wall portion 20b over the entire length of the rear wall portion 20b.

次に、樹脂部材の接合方法について、図８〜図１５に基づいて説明する。
先ず、図８に示すように、バンパーフェース１に当接部１ｃと受止め部１ｄ，１ｅとを予め形成すると共に、オーバーフェンダー２０の接合片２１に係合部２１ｃと受止め部２１ｄ，２１ｅとを予め形成しておく。次に、図９、図１０に示すように、バンパーフェース１のスリット孔１２の第１孔部１２ａにオーバーフェンダー２０の接合片２１を挿入し、図１１に示すように、バンパーフェース１の延出部１ｂの右側において、第１孔部１２ａの上下部分に接合片２１の受止め部２１ｄ，２１ｅを当接させた状態で、接合片２１を第２孔部１２ｂへ移行させ、バンパーフェース１の受止め部１ｄ，１ｅとオーバーフェンダー２０の受止め部２１ｄ，２１ｅとを当接させ、接合片２１の弾性変形復元力で接合片２１の係合部２１ｃをバンパーフェース１の当接部１ｃに位置付ける。 Next, a method for joining resin members will be described with reference to FIGS.
First, as shown in FIG. 8, an abutting portion 1c and receiving portions 1d and 1e are formed in advance on the bumper face 1, and an engaging portion 21c and receiving portions 21d and 21e are formed on the joining piece 21 of the over fender 20. Are formed in advance. Next, as shown in FIGS. 9 and 10, the joining piece 21 of the over fender 20 is inserted into the first hole 12a of the slit hole 12 of the bumper face 1, and the bumper face 1 is extended as shown in FIG. On the right side of the protruding portion 1b, with the receiving portions 21d and 21e of the joining piece 21 in contact with the upper and lower portions of the first hole portion 12a, the joining piece 21 is moved to the second hole portion 12b, and the bumper face 1 The receiving portions 1d, 1e of the overfender 20 and the receiving portions 21d, 21e of the over fender 20 are brought into contact with each other. Position.

次に、図１２、図１３の２点鎖線で示すように、バンパーフェース１の受止め部１ｄ，１ｅと接合片２１の受止め部２１ｄ，２１ｅを当接させ且つ接合片２１の係合部２１ｃをバンパーフェース１の当接部１ｃに係合させた状態で、第２孔部１２ｂから車幅方向内側に突出する接合片２１の折り曲げ部２１ｂを、バンパーフェース１の接合部１３へほぼ直角に折り曲げて、接合片２１の折り曲げ部２１ｂをバンパーフェース１の接合部１３に接触させる。   Next, as indicated by a two-dot chain line in FIGS. 12 and 13, the receiving portions 1 d and 1 e of the bumper face 1 and the receiving portions 21 d and 21 e of the joining piece 21 are brought into contact with each other and the engaging portion of the joining piece 21 is brought into contact. In a state where 21c is engaged with the abutting portion 1c of the bumper face 1, the bent portion 21b of the joining piece 21 protruding inward in the vehicle width direction from the second hole portion 12b is substantially perpendicular to the joining portion 13 of the bumper face 1. The bent portion 21 b of the joining piece 21 is brought into contact with the joining portion 13 of the bumper face 1.

次に、図１４に示すように、超音波溶着器４０の先端部の溶着ホーンで接合片２１の折り曲げ部２１ｂを押圧し、接合片２１の折り曲げ部２１ｂをバンパーフェース１の接合部１３に溶着する。尚、溶着ホーンはローレットタイプのものが装着され、１ヶ所の溶着に要する超音波の発振時間を約０．７５ｓｅｃに設定して行うものとする。すると、図１５に示すように、接合片２１の折り曲げ部２１ｂとバンパーフェース１の接合部１３が軟化し塑性流動することで接合片２１の折り曲げ部２１ｂがバンパーフェース１の接合部１３に溶着され、優れた接合強度を有する接合部３１を形成する。   Next, as shown in FIG. 14, the bent portion 21 b of the joining piece 21 is pressed with a welding horn at the tip of the ultrasonic welder 40, and the bent portion 21 b of the joining piece 21 is welded to the joining portion 13 of the bumper face 1. To do. The welding horn is a knurled type, and the ultrasonic oscillating time required for welding at one place is set to about 0.75 sec. Then, as shown in FIG. 15, the bent portion 21 b of the joint piece 21 and the joint portion 13 of the bumper face 1 are softened and plastically flow, whereby the bent portion 21 b of the joint piece 21 is welded to the joint portion 13 of the bumper face 1. The joining portion 31 having excellent joining strength is formed.

次に、以上説明した樹脂部材の接合方法及びその接合構造についての効果について説明する。
このように、バンパーフェース１の受止め部１ｄ，１ｅと接合片２１の受止め部２１ｄ，２１ｅを当接させ且つ接合片２１の係合部２１ｃをバンパーフェース１の当接部１ｃに係合させた状態で、スリット孔１２の第２孔部１２ｂから突出する接合片２１をバンパーフェース１の接合部１３へほぼ直角に折り曲げて、接合片２１の折り曲げ部２１ｂをバンパーフェース１の接合部１３に溶着し、この接合片２１とスリット孔１２が複数組適当間隔をあけて設けられるので、バンパーフェース１に対するオーバーフェンダー２０の組付け時にスリット孔１２と接合片２１との間で生じる位置ズレを防止することができ、バンパーフェース１とオーバーフェンダー２０との間の相対位置を適切（均一）に保持することができる。それ故、バンパーフェース１とオーバーフェンダー２０との接合品質が向上する。しかも、バンパーフェース１に対するオーバーフェンダー２０の相対位置を保持することができるので組付け性が良い。 Next, effects of the resin member joining method and the joining structure described above will be described.
In this manner, the receiving portions 1d and 1e of the bumper face 1 and the receiving portions 21d and 21e of the joining piece 21 are brought into contact with each other, and the engaging portion 21c of the joining piece 21 is engaged with the contacting portion 1c of the bumper face 1 In this state, the joining piece 21 protruding from the second hole portion 12b of the slit hole 12 is bent at a substantially right angle to the joining portion 13 of the bumper face 1, and the bent portion 21b of the joining piece 21 is bent to the joining portion 13 of the bumper face 1. Since a plurality of sets of the joining pieces 21 and the slit holes 12 are provided at an appropriate interval, the positional deviation generated between the slit holes 12 and the joining pieces 21 when the over fender 20 is assembled to the bumper face 1 is prevented. Therefore, the relative position between the bumper face 1 and the over fender 20 can be maintained appropriately (uniformly). Therefore, the bonding quality between the bumper face 1 and the over fender 20 is improved. Moreover, since the relative position of the over fender 20 with respect to the bumper face 1 can be maintained, the assemblability is good.

また、接合片２１は折り曲げ部２１ｂの左端部分において、折り曲げ方向に弾性変形可能に予め構成され、接合片２１の弾性変形復元力で接合片２１の係合部２１ｃがバンパーフェース１の当接部１ｃに係合可能に位置付けされるので、バンパーフェース１とオーバーフェンダー２０との間の相対位置を安定的に適切（均一）に保持することができる。また、超音波溶着器４０で溶着するので、バンパーフェース１にオーバーフェンダー２０を確実に溶着することができる。   Further, the joining piece 21 is preliminarily configured to be elastically deformable in the bending direction at the left end portion of the bent portion 21b, and the engaging portion 21c of the joining piece 21 is brought into contact with the bumper face 1 by the elastic deformation restoring force of the joining piece 21. Since it is positioned so as to be engageable with 1c, the relative position between the bumper face 1 and the over fender 20 can be stably and appropriately (uniformly) held. Further, since the welding is performed by the ultrasonic welder 40, the over fender 20 can be reliably welded to the bumper face 1.

次に、前記実施例を部分的に変更した変更例について説明する。
１］上記実施例においては、接合片２１の折り曲げ部２１ｂを、バンパーフェース１の接合部１３へ折り曲げた後、超音波溶着器４０の先端部の溶着ホーンで接合片２１の折り曲げ部２１ｂを押圧して溶着したが、予め折り曲げておかずに、溶着ホーンで接合片２１の折り曲げ部２１ｂを押圧して接合片２１の折り曲げ部２１ｂを折り曲げながら溶着してもよい。これによりバンパーフェース１とオーバーフェンダー２０の接合に要する作業時間を短縮することができる。 Next, a modified example in which the above embodiment is partially modified will be described.
1] In the above embodiment, the bent portion 21b of the bonding piece 21 is bent to the bonding portion 13 of the bumper face 1, and then the bent portion 21b of the bonding piece 21 is pressed by the welding horn at the tip of the ultrasonic welder 40. However, instead of bending in advance, the bent portion 21b of the joining piece 21 may be pressed with a welding horn to bend the bent portion 21b of the joining piece 21 while being bent. Thereby, the work time required for joining the bumper face 1 and the over fender 20 can be shortened.
