FIG.

実施の形態１．
以下、実施の形態１に係る車載機器として、図１に示す車載情報機器１を例に用いて、その詳細を説明する。図１に示すように、車載情報機器１は、底面２および両側面３，４からなるメインシャーシ５と、フロントシャーシ６と、組み付け可能なリアシャーシ（カバー）７と、基板８とを備える。図示例ではメインシャーシ５およびフロントシャーシ６がシャーシに相当し、リアシャーシ７が組み付く面をシャーシの開口部９とする。 Embodiment 1 FIG.
Hereinafter, as an in-vehicle device according to Embodiment 1, the in-vehicle information device 1 shown in FIG. As shown in FIG. 1, the in-vehicle information device 1 includes a main chassis 5 having a bottom surface 2 and both side surfaces 3, 4, a front chassis 6, a rear chassis (cover) 7 that can be assembled, and a substrate 8. In the illustrated example, the main chassis 5 and the front chassis 6 correspond to chassis, and the surface to which the rear chassis 7 is assembled is referred to as an opening 9 of the chassis.

図１に示すように、メインシャーシ５の側面３，４には、基板８の側縁部を挟み込んで厚み方向を保持する一対の弾性挟持部１０，１１を、複数対、メインシャーシ５を切り起こして形成する。図２は、車載情報機器１を図１に示すＡＡ線に沿って切断した断面図である。この図２に示すように、一対の弾性挟持部１０，１１は、互いに向かい合う方向に屈曲させて、基板８の表面に接する頂点１０ａと、裏面に接する頂点１１ａとを形成する。図２に示す２つの矢印方向のどちら側からでも基板８を挿入およびスライド移動可能である。   As shown in FIG. 1, the side surfaces 3 and 4 of the main chassis 5 are cut into a plurality of pairs of elastic holding portions 10 and 11 that hold the side edges of the substrate 8 and hold the thickness direction. Wake up and form. 2 is a cross-sectional view of the in-vehicle information device 1 cut along the line AA shown in FIG. As shown in FIG. 2, the pair of elastic clamping portions 10 and 11 are bent in directions facing each other to form a vertex 10 a that contacts the surface of the substrate 8 and a vertex 11 a that contacts the back surface. The substrate 8 can be inserted and slid from either side of the two arrows shown in FIG.

図３（ａ）に弾性挟持部１０，１１の頂点１０ａ，１１ａをずらした構成例を示し、図３（ｂ）に頂点１０ａ，１１ａを同位置にした構成例を示す。弾性挟持部１０，１１の互いに向かい合う頂点１０ａ，１１ａの位置をずらすことにより、同じ位置にした場合に比べて、頂点１０ａ，１１ａそれぞれの高さＨ１，Ｈ２を高くできる。高さＨ１，Ｈ２を高くすれば、弾性挟持部１０，１１が基板８に乗り上がってたわむ量が大きくなるので、基板８を挟持する弾性力を高めることになる。このように、頂点１０ａ，１１ａの高さＨ１，Ｈ２を変更することにより、一対の弾性挟持部１０，１１が基板８を挟持する弾性力を調整できるようになり、弾性力の調整幅を持たせることができる。   FIG. 3A shows a configuration example in which the vertices 10a and 11a of the elastic clamping portions 10 and 11 are shifted, and FIG. 3B shows a configuration example in which the vertices 10a and 11a are in the same position. By shifting the positions of the vertices 10a and 11a facing each other of the elastic clamping portions 10 and 11, the heights H1 and H2 of the vertices 10a and 11a can be increased as compared with the case where they are the same position. If the heights H1 and H2 are increased, the amount of deflection of the elastic clamping portions 10 and 11 riding on the substrate 8 increases, so that the elastic force for clamping the substrate 8 is increased. As described above, by changing the heights H1 and H2 of the vertices 10a and 11a, the elastic force by which the pair of elastic holding portions 10 and 11 hold the substrate 8 can be adjusted, and there is an adjustment range of the elastic force. Can be made.

図４は、メインシャーシ５に基板８を固定した車載情報機器１の、リアシャーシ７取り付け前の状態を示し、図５は、リアシャーシ７を取り付ける途中の状態を示す。また、図６は、図５に示す丸枠内の拡大図である。リアシャーシ７の一方の側縁部に２つの係合部１２を、他方の側縁部にも２つの係合部１２を形成する。他方、メインシャーシ５の側面３，４の開口部９側の縁部に、リアシャーシ７の各係合部１２に係合する係合部１３をそれぞれ形成する。なお、図示例では、互いに係合し合う一対の係合部１２，１３を４組設けたが、これに限定されるものではなく、任意の位置に任意の組数設ければよい。   FIG. 4 shows a state before the rear chassis 7 is attached to the in-vehicle information device 1 in which the substrate 8 is fixed to the main chassis 5, and FIG. 5 shows a state in the middle of attaching the rear chassis 7. FIG. 6 is an enlarged view inside the round frame shown in FIG. Two engaging portions 12 are formed on one side edge portion of the rear chassis 7, and two engaging portions 12 are also formed on the other side edge portion. On the other hand, engaging portions 13 that engage with the engaging portions 12 of the rear chassis 7 are formed at the edges of the side surfaces 3 and 4 of the main chassis 5 on the opening 9 side. In the illustrated example, four pairs of engaging portions 12 and 13 that engage with each other are provided. However, the present invention is not limited to this, and an arbitrary number of sets may be provided at arbitrary positions.

図７は、メインシャーシ５の底面２とリアシャーシ７の掛止部分を拡大した図である。また、図８に、車載情報機器１を図１に示すＢＢ線に沿って切断した断面図を示す。リアシャーシ７の下縁部にくの字形状の引掛け部１４を切り起こして形成する。他方、メインシャーシ５の底面２の開口部９側の縁部に突片１５を設け、この突片１５を開設して、リアシャーシ７の引掛け部１４を引掛ける引掛け穴１６にする。図８に示すように、引掛け部１４を形成した際のリアシャーシ７の切り起こし曲げ部分の屈曲角度θは、掛止状態が外れにくい角度であればよいが、鋭角にはせず、直角より若干の傾斜を付けた鈍角にする。また、突片１５の上端部１５ａを曲げて、引掛け部１４をスライド移動させやすくする。   FIG. 7 is an enlarged view of the bottom surface 2 of the main chassis 5 and the hooking portion of the rear chassis 7. 8 shows a cross-sectional view of the in-vehicle information device 1 cut along the line BB shown in FIG. A dog-shaped hook 14 is cut and raised at the lower edge of the rear chassis 7. On the other hand, a projecting piece 15 is provided at the edge of the bottom surface 2 of the main chassis 5 on the opening 9 side, and this projecting piece 15 is opened to form a hooking hole 16 for hooking the hooking section 14 of the rear chassis 7. As shown in FIG. 8, the bending angle θ of the cut-and-raised bent portion of the rear chassis 7 when the hooking portion 14 is formed may be an angle at which the hooked state is difficult to come off. Use an obtuse angle with a slight inclination. Further, the upper end portion 15a of the projecting piece 15 is bent to facilitate the sliding movement of the hooking portion 14.

なお、図示例では、引掛け部１４をリアシャーシ７に設け、引掛け穴１６をメインシャーシ５の底面２に設ける構成にしたが、反対に、引掛け部１４をメインシャーシ５の底面２に設け、引掛け穴１６をリアシャーシ７に設けてもよい。また、引掛け部１４と引掛け穴１６を１組設けたが、これに限定されるものではなく、任意の位置に任意の組数設ければよい。   In the illustrated example, the hooking portion 14 is provided in the rear chassis 7 and the hooking hole 16 is provided in the bottom surface 2 of the main chassis 5. On the contrary, the hooking portion 14 is provided in the bottom surface 2 of the main chassis 5. The hook 16 may be provided in the rear chassis 7. Further, although one set of the hooking portion 14 and the hooking hole 16 is provided, the present invention is not limited to this, and an arbitrary number of sets may be provided at arbitrary positions.

リアシャーシ７には、リアシャーシ７の内側に突出して基板８をフロントシャーシ６側へ弾性押圧する弾性押圧部１７を２つ、リアシャーシ７を切り起こして形成する。これら弾性押圧部１７が基板８を手前側から押圧することにより、基板８の奥側がフロントシャーシ６に突き当たって保持され、奥行き方向に固定される。   In the rear chassis 7, two elastic pressing portions 17 that protrude inward of the rear chassis 7 and elastically press the substrate 8 toward the front chassis 6 are formed by cutting and raising the rear chassis 7. When these elastic pressing portions 17 press the substrate 8 from the front side, the back side of the substrate 8 abuts against the front chassis 6 and is held and fixed in the depth direction.

図９は、車載情報機器１を図５に示すＣＣ線に沿って切断した断面図であり、弾性押圧部１７を拡大して示す。図９に詳細に示すように、弾性押圧部１７は、リアシャーシ７をメインシャーシ５に取り付ける際のスライド方向（図９に示す矢印方向）の先頭側に切り起こし曲げた固定端１７ａを設ける。そして、この固定端１７ａから屈曲部１７ｂへ向けて徐々にシャーシ内側に突出する形状にし、リアシャーシ７が矢印方向へスライド移動する際に基板８の端部に引っ掛からないようにして、挿入しやすくする。また、リアシャーシ７を矢印方向へスライド移動させればさせるほど、弾性押圧部１７の自由端１７ｃ側が基板８の端部に押し返されてたわむので、この基板８をフロントシャーシ６側に押圧する力が強くなる。   FIG. 9 is a cross-sectional view of the in-vehicle information device 1 taken along the line CC shown in FIG. 5 and shows the elastic pressing portion 17 in an enlarged manner. As shown in detail in FIG. 9, the elastic pressing portion 17 is provided with a fixed end 17 a that is cut and raised on the leading side in the sliding direction (arrow direction shown in FIG. 9) when the rear chassis 7 is attached to the main chassis 5. Then, it is formed so that it gradually protrudes from the fixed end 17a toward the bent portion 17b toward the inside of the chassis so that the rear chassis 7 does not get caught at the end of the substrate 8 when sliding in the direction of the arrow. To do. Further, as the rear chassis 7 is slid in the direction of the arrow, the free end 17c side of the elastic pressing portion 17 is pushed back and bent toward the end of the substrate 8, so that the substrate 8 is pressed toward the front chassis 6 side. Strength becomes stronger.

なお、図示例では、弾性押圧部１７を２箇所に設ける構成にしたが、これに限定されるものではなく、任意の位置に任意の組数設ければよい。   In the illustrated example, the elastic pressing portions 17 are provided at two locations. However, the configuration is not limited to this, and an arbitrary number of sets may be provided at arbitrary positions.

次に、車載情報機器１の組立方法を説明する。
先ず、メインシャーシ５とフロントシャーシ６からなるシャーシの開口部９より内部へ、基板８を挿入して固定する。このとき、基板８の両側縁部が弾性挟持部１０，１１の間を通るようにスライド移動させて、基板８の奥側をフロントシャーシ６に突き当てる。すると、図４に示すように、基板８の両側縁部が弾性挟持部１０，１１に表裏方向から挟持されるので、基板８の厚み方向を固定できる。また、基板８の幅方向は側面３，４に当接して固定される。 Next, a method for assembling the in-vehicle information device 1 will be described.
First, the board 8 is inserted and fixed to the inside through the opening 9 of the chassis composed of the main chassis 5 and the front chassis 6. At this time, the both side edges of the substrate 8 are slid so as to pass between the elastic clamping portions 10 and 11, and the back side of the substrate 8 is abutted against the front chassis 6. Then, as shown in FIG. 4, both side edges of the substrate 8 are sandwiched by the elastic sandwiching portions 10 and 11 from the front and back directions, so that the thickness direction of the substrate 8 can be fixed. The width direction of the substrate 8 is fixed in contact with the side surfaces 3 and 4.

続いて、リアシャーシ７を開口部９に取り付ける。このとき、係合部１２それぞれを係合部１３それぞれに係合させてリアシャーシ７とメインシャーシ５の位置を決め、その状態からリアシャーシ７を下方へスライド移動させて引掛け部１４を引掛け穴１６に掛止させる。すると、図１に示すように、係合部１２，１３の係合と、引掛け部１４の引掛け穴１６への掛止とにより、リアシャーシ７とメインシャーシ５とを固定できる。また、２つの弾性押圧部１７により、基板８がリアシャーシ７側からフロントシャーシ６側へ押圧されるので、基板８の奥行き方向を固定できる。   Subsequently, the rear chassis 7 is attached to the opening 9. At this time, each of the engaging portions 12 is engaged with each of the engaging portions 13 to determine the positions of the rear chassis 7 and the main chassis 5, and the rear chassis 7 is slid downward from the state to pull the hooking portion 14. Hang in the hanging hole 16. Then, as shown in FIG. 1, the rear chassis 7 and the main chassis 5 can be fixed by the engagement of the engagement portions 12 and 13 and the engagement of the hook portion 14 with the hook hole 16. Moreover, since the board | substrate 8 is pressed from the rear chassis 7 side to the front chassis 6 side by the two elastic press parts 17, the depth direction of the board | substrate 8 can be fixed.

なお、図１０の上面図に示すように基板８の両側縁部それぞれの一部を切り欠いて切欠部１８を形成してもよい。シャーシに基板８を固定する際、切欠部１８に開口部９側の弾性挟持部１０，１１がはまるようにシャーシ上面の開口から基板８を挿入して、その位置からフロントシャーシ６側へスライド移動させる。図１０に示す構成の場合には、図１〜図９に示す構成に比べて基板８のスライド距離を短くできる。   In addition, as shown in the top view of FIG. 10, a part of each edge part of the board | substrate 8 may be notched, and the notch part 18 may be formed. When the board 8 is fixed to the chassis, the board 8 is inserted from the opening on the upper surface of the chassis so that the elastic clamping parts 10 and 11 on the side of the opening 9 are fitted in the notch part 18 and slides from the position to the front chassis 6 side. Let In the case of the configuration shown in FIG. 10, the sliding distance of the substrate 8 can be shortened as compared with the configurations shown in FIGS. 1 to 9.

また、図１１の外観斜視図に示すように基板８の奥側の端部に基板間接続コネクタ１９を取り付け、フロントシャーシ６に固定された基板２０の基板間接続コネクタ２１に接続させてもよい。図１１に示す構成の場合には、基板間接続コネクタ２１が当てとなり、２つの弾性押圧部１７が基板８をリアシャーシ７側からフロントシャーシ６側へ押圧して、基板８の奥行き方向を固定する。   Further, as shown in an external perspective view of FIG. 11, an inter-board connector 19 may be attached to the back end of the board 8 and connected to the inter-board connector 21 of the board 20 fixed to the front chassis 6. . In the case of the configuration shown in FIG. 11, the inter-board connector 21 is applied, and the two elastic pressing portions 17 press the board 8 from the rear chassis 7 side to the front chassis 6 side to fix the depth direction of the board 8.
