Description

本発明は、板金のウェルドナット取り付け部等に用いて好適の、板材接合部の補強構造に関するものである。   The present invention relates to a reinforcing structure for a plate material joint, which is suitable for use in a weld nut mounting portion of a sheet metal.

従来より、自動車の艤装品等の部品取り付け部（板材接合部）では、板材にナット（ウェルドナット）を溶着し、このウェルドナットにボルトを締結して部品を取り付けるような手法が広く用いられている。
しかし、このような取り付け手法では、ボルトに軸力や曲げモーメントが作用すると、ウェルドナットの溶着部に応力集中が生じるため耐久性が低下してしまう。そこで、耐久寿命を延ばす目的で、被締結部の板厚を増大させたり、又は応力を低減する目的でナットプレートが使用されたりしているが、このような板厚増大やナットプレートの使用はコストの増大を招くほか重量増を招くことになる。 2. Description of the Related Art Conventionally, in parts attachment parts (plate material joints) such as automobile fittings, a method has been widely used in which a nut (weld nut) is welded to a plate material, and bolts are fastened to the weld nut to attach parts. Yes.
However, in such a mounting method, when an axial force or a bending moment acts on the bolt, stress concentration occurs in the welded portion of the weld nut, resulting in a decrease in durability. Therefore, for the purpose of extending the durability life, the nut plate is used for the purpose of increasing the plate thickness of the fastened part or reducing the stress, but such plate thickness increase or use of the nut plate is not used. In addition to an increase in cost, this also increases the weight.

なお、下記の特許文献１には、六角ボルトと六角ナットとにより固定される金物において、六角ボルトを挿入するボルト穴の中心から対称に２個の凸部を形成した技術が開示されている。
実用新案登録第３０４４７０５号公報 The following Patent Document 1 discloses a technique in which two protrusions are formed symmetrically from the center of a bolt hole into which a hexagon bolt is inserted in a hardware fixed by a hexagon bolt and a hexagon nut.
Utility Model Registration No. 30447705

しかしながら、上記特許文献の技術は、板材の接合部においてボルト又はナットを締結する際の共回りを防止するための技術であって、板材接合部の応力集中を低減できるようなものではなかった。
本発明は、このような課題に鑑み創案されたもので、コスト増や重量増を招くことなく板材接合部の応力集中の低減を図るようにした、板材接合部の補強構造を提供することを目的とする。 However, the technique of the above-mentioned patent document is a technique for preventing co-rotation at the time of fastening a bolt or a nut at a joint portion of the plate material, and cannot reduce stress concentration at the plate material joint portion.
The present invention was devised in view of such a problem, and provides a reinforcing structure for a plate material joint that reduces the stress concentration of the plate material joint without causing an increase in cost or weight. Objective.

本発明の板材接合部の補強構造は、板材を他の部材に接合する接合部の周囲に***部が形成され、該***部が該接合部を中心とする略環状または略円弧状に形成されていることを特徴としている。
また、該***部が該接合部を中心とする円弧状に形成されていてもよい。この場合には、該円弧状の***部が複数形成されるとともに、該複数の***部が該接合部を中心として対称な位置に形成されているのが好ましい。 In the reinforcing structure of the plate material joint portion according to the present invention, a raised portion is formed around the joint portion for joining the plate material to another member, and the raised portion is formed in a substantially annular shape or a substantially arc shape centering on the joint portion. It is characterized by having.
Further, the raised portion may be formed in an arc shape centering on the joint portion. In this case, it is preferable that a plurality of the arcuate ridges are formed, and the plurality of bulges are formed at symmetrical positions around the joint.

また、該***部の断面形状が略半円形状に形成されるのが好ましい。この場合は、該板材の平面部と該***部との境目の断面形状は、連続した曲面で形成されているのが好ましい。
また、該板材は金属であるのが好ましい。
また、該接合部がウェルドナット又はウェルドボルトの取り付け部であってもよいし、該接合部がボルト又はナットの取り付け部であってもよい。さらには、該接合部が溶接による接合箇所であってもよい。この場合、溶接としてはスポット溶接やプラグ溶接等に適用可能である。 Moreover, it is preferable that the cross-sectional shape of the raised portion is formed in a substantially semicircular shape. In this case, it is preferable that the cross-sectional shape of the boundary between the flat portion of the plate material and the raised portion is a continuous curved surface.
The plate material is preferably a metal.
Further, the joint portion may be a weld nut or weld bolt attachment portion, or the joint portion may be a bolt or nut attachment portion. Furthermore, the joint portion may be a joint portion by welding. In this case, the welding can be applied to spot welding or plug welding.

本発明の板材接合部の補強構造によれば、簡素な構造でコスト増や重量増を招くことなく接合部の応力集中を低減することができ、部品取り付け剛性の向上、耐久性の大幅な向上を図ることができるという利点がある。   According to the reinforcing structure of the plate joint part of the present invention, the stress concentration at the joint part can be reduced with a simple structure without causing an increase in cost and weight, and the rigidity of component attachment is improved and the durability is greatly improved. There is an advantage that can be achieved.

以下、図面により、本発明の一実施形態に係る板材接合部の補強構造について説明すると、図１はその要部を示す模式的な斜視図、図２はその変形例について示す模式的な平面図、図３は図１におけるＡ−Ａ断面図である。また、図４〜図１０はいずれも本発明をウェルドナットの取り付け部に適用した場合における有限要素解析（ＦＥＡ）について説明するための図である。また、図１１と図１２はいずれも本発明をウェルドナットの取り付け部に適用した場合における応力について説明するための図である。   Hereinafter, a reinforcing structure for a plate material joint according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a schematic perspective view showing the main part, and FIG. 2 is a schematic plan view showing a modification thereof. 3 is a cross-sectional view taken along the line AA in FIG. 4 to 10 are diagrams for explaining finite element analysis (FEA) in the case where the present invention is applied to a weld nut mounting portion. Moreover, both FIG. 11 and FIG. 12 is a figure for demonstrating the stress at the time of applying this invention to the attachment part of a weld nut.

図１において、符号１は金属性の板材（板金）であって、この板金１を他の部材に接合する箇所（接合部）２には、ウェルドナット３が設けられている。ここで、ウェルドナット３は本実施形態においては４点で板金１に溶着されており、板金１と一体化されている。
また、図３に示すように、板金１のウェルドナット３のネジ穴３ａに対応した位置には穴１ａが形成されている。また、ウェルドナット３の周囲には、ウェルドナット３のネジ穴３ａを中心に（つまり、板金１に形成された穴１ａを中心に）、図１及び図３に示すようなビード（***部）４が形成されている。ここで、このビード４は、上面視においては、図１に示すような環状又は円形に形成されるとともに、断面形状は図３に示すように略半円形に形成されており、例えばプレス成形により形成される。なお、ビード４の断面形状はこのような半円形に限定されるものではなく、種々の形状が適用可能である。また、本実施形態においては、板金１の平面部とビード４との境目の断面形状は連続した曲面で形成されている。 In FIG. 1, reference numeral 1 denotes a metallic plate material (sheet metal), and a weld nut 3 is provided at a location (joined portion) 2 where the sheet metal 1 is joined to another member. Here, the weld nut 3 is welded to the sheet metal 1 at four points in the present embodiment, and is integrated with the sheet metal 1.
As shown in FIG. 3, a hole 1 a is formed at a position corresponding to the screw hole 3 a of the weld nut 3 of the sheet metal 1. Further, around the weld nut 3, a bead (bump) as shown in FIGS. 1 and 3 is centered on the screw hole 3 a of the weld nut 3 (that is, centered on the hole 1 a formed in the sheet metal 1). 4 is formed. Here, the bead 4 is formed in an annular shape or a circular shape as shown in FIG. 1 in a top view, and a cross-sectional shape is formed in a substantially semicircular shape as shown in FIG. It is formed. In addition, the cross-sectional shape of the bead 4 is not limited to such a semicircular shape, and various shapes are applicable. Moreover, in this embodiment, the cross-sectional shape of the boundary between the flat portion of the sheet metal 1 and the bead 4 is formed as a continuous curved surface.

また、図２に示すように、ビード４を環状にせずに複数に分割するようにしてもよい。この場合には、図示するようにビード４を円弧状に形成するのが好ましく、さらには、接合部２を中心として対称な位置にビード４を配置するのが好ましい。
そして、このように接合部２の周囲にビード４を形成することにより、図示しないボルトに軸力や曲げモーメントが作用しても、ウェルドナット３の溶着部に生じる応力集中を低減することができる。 Further, as shown in FIG. 2, the bead 4 may be divided into a plurality of parts without being annular. In this case, it is preferable to form the bead 4 in an arc shape as shown in the drawing, and it is preferable to arrange the bead 4 at a symmetrical position with the joint 2 as the center.
And by forming the bead 4 around the joint 2 in this way, even if an axial force or a bending moment acts on a bolt (not shown), the stress concentration generated in the welded portion of the weld nut 3 can be reduced. .

これを図４〜図１１を用いて説明すると、図４乃至図６は図１に示すウェルドナット３にボルト５を締結して有限要素解析（ＦＥＡ）を行った際の条件について示す図であって、図示するように、ここでは板金１からの長さＬのボルト５を用い、ボルト５の下端にボルト中心軸と直交する方向から曲げモーメントを加えるとともに、ボルト中心軸と同軸方向に面外軸力（鉛直荷重）を入力した。なお、図示するように、板金１は両端部において単純支持とした。また、図４ではビード４が形成されていないが、環状のビード４を形成した場合とビード４を形成しいない場合との両方を解析した。   This will be described with reference to FIGS. 4 to 11. FIGS. 4 to 6 are diagrams showing conditions when a bolt 5 is fastened to the weld nut 3 shown in FIG. 1 and finite element analysis (FEA) is performed. As shown in the figure, a bolt 5 having a length L from the sheet metal 1 is used here, and a bending moment is applied to the lower end of the bolt 5 from a direction orthogonal to the bolt central axis, and in the direction coaxial with the bolt central axis. Axial force (vertical load) was input. As illustrated, the sheet metal 1 is simply supported at both ends. In FIG. 4, the bead 4 is not formed, but both the case where the annular bead 4 is formed and the case where the bead 4 is not formed are analyzed.

図５はビード無しの場合の要素分割について示す図であって、図６は環状のビード４を設けた場合の要素分割ついて示す図である。これらの図に示すように、本実施形態においては、主に、ウェルドナット３及びボルト４を中心にした同心円と、ボルト中心から放射状に延びる線とにより要素分割を行った。
図７はビード無しの場合における鉛直荷重入力時の応力分布を示す図、図８はビード有りの場合における鉛直荷重入力時の応力分布を示す図である。また、図９はビード無しの場合における曲げモーメント入力時の応力分布を示す図、図１０はビード有りの場合における曲げモーメント入力時の応力分布を示す図である。また、これらの各図の右側には応力の大きさと各要素の模様との関係を示しており、黒で塗りつぶした要素は二次応力が最大となる箇所である。 FIG. 5 is a diagram showing element division when there is no bead, and FIG. 6 is a diagram showing element division when an annular bead 4 is provided. As shown in these drawings, in the present embodiment, the element division is mainly performed by concentric circles centering on the weld nut 3 and the bolt 4 and lines extending radially from the bolt center.
FIG. 7 is a diagram showing a stress distribution when a vertical load is input without a bead, and FIG. 8 is a diagram showing a stress distribution when a vertical load is input with a bead. FIG. 9 is a diagram illustrating a stress distribution when a bending moment is input without a bead, and FIG. 10 is a diagram illustrating a stress distribution when a bending moment is input when a bead is present. Also, the right side of each figure shows the relationship between the magnitude of stress and the pattern of each element, and the elements filled with black are the places where the secondary stress is maximum.

図７に示すように、ビード４を設けていない場合には、鉛直荷重入力時にはウェルドナット３の溶着個所（４箇所）の狭い範囲内に最大応力（図中、黒の塗りつぶし参照）が集中している。したがって、このような荷重が繰り返り作用すると、上記ウェルドナット３の溶着個所で金属疲労が進み、破断が生じたりすることにより耐久寿命が低下してしまうことになる。   As shown in FIG. 7, when the bead 4 is not provided, the maximum stress (refer to the black fill in the figure) is concentrated within a narrow range of weld locations (4 locations) of the weld nut 3 when a vertical load is input. ing. Therefore, when such a load repeatedly acts, the metal fatigue proceeds at the welded portion of the weld nut 3 and breakage occurs, resulting in a decrease in the durability life.

一方、図８に示すように、ビード４を設けた場合には最大応力を受ける面積自体は広がるものの、ウェルドナット３の溶着部での応力集中を回避でき接合部２の耐久寿命が向上する。特にこの場合は、ビード４を環状に形成したので、ビード４の縁部に沿って応力が作用する。このため、応力を板金全体で受けることとになり、ウェルドナット３の溶着部における応力が分散して、この部分での耐久性が向上することとなる。尚、ビード４を円弧状に形成しても、同様の効果を得ることができる。   On the other hand, as shown in FIG. 8, when the bead 4 is provided, the area itself receiving the maximum stress increases, but stress concentration at the welded portion of the weld nut 3 can be avoided, and the durability of the joint portion 2 is improved. Particularly in this case, since the bead 4 is formed in an annular shape, stress acts along the edge of the bead 4. For this reason, stress will be received by the whole sheet metal, the stress in the weld part of the weld nut 3 will disperse | distribute, and the durability in this part will improve. Even if the beads 4 are formed in an arc shape, the same effect can be obtained.

また、板金１の平面部とビード４との境目の断面形状は、応力集中しやすい角部で形成されておらず、連続した曲面で形成されているので、より効果的に応力分散が可能である。
また、図９に示すように、曲げモーメント入力時には、ビード４を設けていない場合には、曲げモーメントの入力方向に応じたウェルドナット３の溶着個所２点（図中上下の２点）に応力が集中していることがわかる。したがって、このような曲げモーメントが繰り返し作用すると、やはりこの溶着点において金属疲労が進み、耐久性が低下してしまう。 Further, the cross-sectional shape of the boundary between the flat portion of the sheet metal 1 and the bead 4 is not formed at the corner portion where stress is likely to concentrate, but is formed as a continuous curved surface, so that stress can be more effectively distributed. is there.
As shown in FIG. 9, when the bead 4 is not provided when a bending moment is input, stress is applied to two weld points (two points at the top and bottom in the figure) of the weld nut 3 in accordance with the input direction of the bending moment. It can be seen that is concentrated. Therefore, when such a bending moment repeatedly acts, the metal fatigue also proceeds at this welding point, and the durability is lowered.

これに対して、図１０に示すように応力の分布の特性は大きく変わらないものの、ウェルドナット３の溶着部に生じる応力の大きさが大幅に低減される。したがって、耐久性の向上に寄与することがわかる。また、ビード４を環状に形成しているので、あらゆる方向の曲げモーメントに対応できる。尚、ビード４を円弧状に形成しても、同様の効果を得ることができる。   On the other hand, as shown in FIG. 10, although the stress distribution characteristics do not change greatly, the magnitude of the stress generated in the welded portion of the weld nut 3 is greatly reduced. Therefore, it turns out that it contributes to the improvement of durability. Moreover, since the bead 4 is formed in an annular shape, it can cope with bending moments in all directions. Even if the beads 4 are formed in an arc shape, the same effect can be obtained.

図１１は鉛直荷重を入力した際に作用する応力を測定したプロット点を示す図、図１２は図１１に示す各プロット点における応力を示すものであって、線ａは環状のビード４を設けなかった場合、線ｂは環状のビード４を設けた場合の特性をそれぞれ示している。
図１２に線ａで示すように、ビード４を設けない場合には各プロット点における応力はナット３の溶着点に近くなるほど（横軸の距離が０に近づくほど）大きい。つまり、溶着点に大きな応力が作用していることを示している。これに対して、線ｂに示すよぅに、ビード４を設けた場合には、溶着点に近づくと僅かに応力が増大するような特性が見られるが、線ａに示すビード無しの場合に比べて明らかに全体的に作用している応力が小さく、ビード４の作用により応力が低減していることがわかる。 FIG. 11 is a diagram showing plot points at which stress acting when a vertical load is input, FIG. 12 shows the stress at each plot point shown in FIG. 11, and line a is provided with an annular bead 4. When there is no line, the line b indicates the characteristics when the annular bead 4 is provided.
As shown by the line a in FIG. 12, when the bead 4 is not provided, the stress at each plot point is larger as the weld point of the nut 3 is closer (as the distance on the horizontal axis is closer to 0). That is, it shows that a large stress is acting on the welding point. On the other hand, as shown by line b, when the bead 4 is provided, a characteristic that the stress slightly increases when approaching the welding point is seen, but compared with the case without the bead shown by the line a. It is apparent that the stress acting as a whole is small and the stress is reduced by the action of the bead 4.

以上詳述したように、本発明の一実施形態に係る板材接合部の補強構造によれば、板材１の接合部２の周囲にビード４を形成するという簡素な構成で応力集中を回避又は低減することができる。これにより、従来用いられていた板厚増大やナットプレート使用という手法を用いる必要がなくなるのでコスト増や重量増を招くことなく応力集中を低減できるとともに、板材１の耐久性を向上させることができるという利点がある。   As described above in detail, according to the reinforcing structure of the plate material joint portion according to one embodiment of the present invention, stress concentration is avoided or reduced with a simple configuration in which the beads 4 are formed around the joint portion 2 of the plate material 1. can do. Thereby, since it is not necessary to use the conventionally used method of increasing the plate thickness or using the nut plate, it is possible to reduce the stress concentration without increasing the cost and the weight, and to improve the durability of the plate 1. There is an advantage.

なお、本発明は上述の実施の形態に限定されるものではなく、本発明の趣旨を逸脱しない範囲で種々の変形例が可能である。例えば、上記の実施形態では、板材１の接合部２としてウェルドナット３の取り付け部を挙げて説明したが、ウェルドボルトの取り付け部であってもよいし、又は単にボルト又はナットの取り付け部であってもよい。さらには、接合部２が溶接による接合箇所であってもよい。この場合、溶接としてはスポット溶接やプラグ溶接等が挙げられる。また、上記実施形態では、板材として金属を用いたが、これに代えて樹脂の板材に本発明を適用してもよい。   The present invention is not limited to the above-described embodiment, and various modifications are possible without departing from the spirit of the present invention. For example, in the above-described embodiment, the weld nut 3 attachment portion has been described as the joining portion 2 of the plate member 1; however, a weld bolt attachment portion may be used, or simply a bolt or nut attachment portion. May be. Furthermore, the joining part 2 may be a joining part by welding. In this case, spot welding, plug welding, etc. are mentioned as welding. Moreover, in the said embodiment, although the metal was used as a board | plate material, it may replace with this and you may apply this invention to the board | plate material of resin.

また、ビード４の断面形状は任意であって、特に限定されるものではなく、さらには板金１の平面部とビード４との境目の断面形状は、連続した曲面で形成されているのが好ましい。また、ビードの平面視における形状も環状又は円弧状にのみ限定されず、楕円形状や、任意の曲線形状等、設計上の要求に応じて種々変更可能である。   Moreover, the cross-sectional shape of the bead 4 is arbitrary and is not particularly limited, and the cross-sectional shape of the boundary between the flat portion of the sheet metal 1 and the bead 4 is preferably formed by a continuous curved surface. . Further, the shape of the bead in plan view is not limited to an annular shape or an arc shape, and can be variously changed according to design requirements such as an elliptical shape or an arbitrary curved shape.
