【発明の属する技術分野】
本発明は、イモビライザユニットの電子制御部を車両に備えるよう電子制御部の取付構造に関するものである。
【０００２】
【従来の技術】
一般に車両には、盗難防止機能として、エンジンを始動させる際にイグニッションスイッチからの信号が正しい信号かどうか参照するイモビライザユニットを設けており、イモビライザユニットにはエンジンの動作全体を制御する電子制御部（ＥＣＵ）を備えている。
【０００３】
又、車両は、電子制御部の交換によりエンジンを始動させることを防止するため、電子制御部の取り外しを困難にするよう構成されており、具体的には、図７に示す如く、ワイヤーハーネス１を接続した電子制御部２をインストルメントパネル３の内部のセンターメンバ４に配置すると共に、センターメンバ４にボルト５を介して電子制御部２の取外防止用カバー６を固定している。ここで、取外防止用カバー６を固定するボルト５は、頭部を円形に形成して工具が係合しないように形成されており、又、取外防止用カバー６の外す方向にはオーディオユニット及び灰皿等の部材７を配置することにより、取外防止用カバー６の取り外しを更に困難にしている。なお、図７中、８は床面、９はシフトレバーを示す。
【０００４】

【００１２】
【発明の実施の形態】
以下、本発明の実施の形態を図示例と共に説明する。
【００１３】
図１〜図６は本発明を実施する形態の一例である。
【００１４】
電子制御部（ＥＣＵ）１０の取付構造は、インストルメントパネル１１のグラブボックス１２の奥側に配置されるよう、インストルメントパネル１１のリンフォース部材１３に取付ブラケット１４及び取外防止用ブラケット１５を介してイモビライザユニットの電子制御部１０を備えている。
【００１５】
電子制御部１０は、所定の立方形状に構成されると共に、ワイヤーハーネス１６のコネクタ部１７を接続し得るコネクタ受部１８を一側面に備え、コネクタ受部１８の他側面２０には、締結孔２１を穿設した固定ブラケット２２を備え、固定ブラケット２２の縁部には下方に突出する係止部２３を設けている。
【００１６】
ここで、リンフォース部材１３は所定の間隔を介して二本の腕状ブラケット２４を備え、腕状ブラケット２４の先端側には上方へ突出するボルト部材２５を夫々立設している。
【００１７】
一方、リンフォース部材１３に取り付ける取付ブラケット１４は、腕状ブラケット２４の間に配置されるよう、底面部２６の両側に所定高さの段差部２７を介して取付部２８を備えており、取付部２８の両側端には取付孔２９を穿設し、底面部２６から段差部２７を介する取付部２８までの一側端には上方へ立設する縁部３０を備え、縁部３０の両端部には、取付孔２９に隣接するよう上方へ延在する取外防止リブ３１を備えると共に、縁部３０の中央部には、所定の高さまで上方へ延在する溶接用リブ３２を備えている。
【００１８】
取付ブラケット１４には取外防止用ブラケット１５を配置しており、取外防止用ブラケット１５は、取付ブラケット１４の底面部２６より大きい面を備えて反縁部側に突出する配置底面部３３と、配置底面部３３の両側に形成されて段差部２７よりも高く形成されるガード側壁３４と、溶接用リブ３２に面する背側ガード側壁３５とを備え、且つ取付ブラケット１４の底面部２６に配置底面部３３をスポット溶接する（図２ではＸ印の位置）と共に、取付ブラケット１４の溶接用リブ３２に背側ガード側壁３５をスポット溶接する（図２ではＸ印の位置）ことにより、取付ブラケット１４に一体に固定されている。又、配置底面部３３の突出側の先端には、上方へ突出するボルト部材３６を備えると共に、ボルト部材３６の隣接位置に係止孔３７を穿設しており、更にガード側壁３４には、ワイヤーハーネス１６のコネクタ部１７よりも狭く形成される開口３８を備えると共に、開口３８の周囲部３９に外側へ折り返して形成される補強部４０を備えている。ここで、図２中、４１は電子制御部１０が取外防止用ブラケット１５の配置底面部３３に直接当たることを防止するクッションである。なお、ガード側壁３４に構成される開口３８は一方のガード側壁３４に備えてもよいし、両側のガード側壁３４に備えて左右両側で共用できるようにしてもよい。
【００１９】
以下、本発明を実施する形態例の作用を説明する。
【００２０】
インストルメントパネル１１のリンフォース部材１３に、取付ブラケット１４及び取外防止用ブラケット１５を介して電子制御部１０を取り付ける際には、図３に示す如く、初めに、電子制御部１０のコネクタ受部１８にワイヤーハーネス１６のコネクタ部１７を差し込み、次に、電子制御部１０の固定ブラケット２２の締結孔２１を取外防止用ブラケット１５のボルト部材３６に挿通させると共に、固定ブラケット２２の係止部２３を取外防止用ブラケット１５の係止孔３７に係止させ、ボルト部材３６にナット（図示せず）を締結することにより電子制御部１０を取外防止用ブラケット１５に固定する。ここで、電子制御部１０のワイヤーハーネス１６はガード側壁３４の開口３８に通して配置される。
【００２１】
電子制御部１０を取外防止用ブラケット１５に固定した後には、腕状ブラケット２４のボルト部材２５に取付ブラケット１４の取付孔２９を挿通してナット４２を締結することにより取付ブラケット１４をリンフォース部材１３に固定する。ここでナット４２を締結する際には、取外防止リブ３１に接触しないようナット４２（締結部材）を固定し得るボックスレンチ（図示せず）を用いる。
【００２２】
更に、取付ブラケット１４を腕状ブラケット２４に固定することによって電子制御部１０をリンフォース部材１３に取り付けた後には、電子制御部１０の上部に他の機器（図示せず）を配置させる。
【００２３】
一方、電子制御部１０をリンフォース部材１３に取り付けた後、盗難等で電子制御部１０を上方（図３ではＵＰ）に取り外そうとする際には、電子制御部１０の上方に配置する他の機器（図示せず）が障害物になり、電子制御部１０を前方（図３ではＦｒ）に取り外そうとする際には、取外防止用ブラケット１５の背側ガード側壁３５が障害物になり、電子制御部１０を側方（図３ではＲｈ）に取り外そうとする際には、取外防止用ブラケット１５のガード側壁３４が障害物になり、電子制御部１０を後方（図３ではＲｒ）に取り外そうとする際にはリンフォース部材１３が障害物になる。
【００２４】
ここで、腕状ブラケット２４と取付ブラケット１４を固定するナット４２を取り外そうとする際には、図６に示す如く、取外防止リブ３１が障害となるため、スパナ等の工具Ｓを使用することはできず、電子制御部１０の固定ブラケット２２と取付ブラケット１４を固定するボルト（図示せず）を取り外そうとする際には、リンフォース部材１３が障害となるため、同様にスパナ等の工具Ｓを使用することはできない。
【００２５】
又、電子制御部１０のコネクタ受部１８よりワイヤーハーネス１６のコネクタ部１７を無理に引き抜こうとする際には、図４に示す如く、取外防止用ブラケット１５のガード側壁３４における開口３８の周囲部３９が障害物となる。又、ワイヤーハーネス１６のコネクタ部１７を更に無理に引き抜こうとする際には、図５に示す如く、取付ブラケット１４の段差部２７が障害物になる。
【００２６】
このように、電子制御部１０を取り外そうとする際には、取外防止用ブラケット１５に備えられた背側ガード側壁３５及びガード側壁３４、リンフォース部材１３、電子制御部１０の上方に位置する他の部材が障害物になるので、取外防止用ブラケット１５を簡単な構造にして取外用カバーを不要にし得ると共に電子制御部１０の取り外しを困難にすることができる。又、取外防止用ブラケット１５を取付ブラケット１４に一体に設けるので、取外防止用カバーと略同様な作用をする取外防止用ブラケット１５の取り付けを容易にし、結果的に、取付作業において手間を低減し、製造コストを抑制することができる。
【００２７】
取外防止用ブラケット１５は、電子制御部１０に接続したワイヤーハーネス１６の配置側にガード側壁３４を備え、前記ガード側壁３４には、ワイヤーハーネス１６を通し且つコネクタ部１７よりも狭く形成される開口３８を備えると共に、開口３８の周囲部３９に折り返しの補強部４０を備えており、取付ブラケット１４は、前記開口３８に面してコネクタ部１７の引き抜きを防止する段差部２７を備えると、ワイヤーハーネス１６のコネクタ部１７を電子制御部１０より無理に引き抜こうとする際には、取外防止用ブラケット１５のガード側壁３４における開口３８の周囲部３９が障害物となると共に、補強部４０が開口３８の周囲部３９を補強して開口３８の変形を防止するので、コネクタ部１７の引き抜きを防止することができる。又、ワイヤーハーネス１６のコネクタ部１７を更に無理に引き抜こうとする際には、取付ブラケット１４の段差部２７が開口３８の周囲部３９及び補強部４０と共に障害物になるので、コネクタ部１７の引き抜きを確実に防止することができる。
【００２８】
取付ブラケット１４は、リンフォース部材１３にナット４２（締結部材）を介して取り付ける取付部２８を備え、前記取付部２８には、締結部材の取り外しを困難にするよう締結部材に隣接する取外防止リブ３１を備えると、工具により締結部材を取り外す際には、取外防止リブ３１が工具操作の障害物になるので、締結部材の取り外しを防止することができる。
【００２９】
なお、本発明の電子制御部の取付構造は上述の形態例のみに限定されるものではなく、本発明の要旨を逸脱しない範囲内において種々変更を加え得ることは勿論である。
【００３０】
