Description

本発明は、車両用の電装部品を車両に取り付けるための取付構造に関する。   The present invention relates to a mounting structure for mounting a vehicle electrical component to a vehicle.

エンジンコントロールユニット（Engine Control Unit；以下、ＥＣＵと云う）などの車両用電装部品は、性能を維持するために使用環境の温度に制約がある。エンジンルームは発熱部品が多いため雰囲気温度が高く、電装部品の配置に制限がある。電装部品は、雰囲気温度が制限温度以下の場所に取り付ける必要がある。電装部品の配置場所として、カウル部が選定される場合がある。カウル部とは、エンジンルームよりも車両前後方向後側で、車室よりも車両前後方向前側で、かつフロントガラスの車両前後方向前側の下端部に位置する。このように、カウル部はフロントガラスの下端部に位置するため、フロントガラスを伝わってきた水などがカウル部内に浸入する場合がある。カウル部内に電装部品を配置した場合、電装部品が水によって故障する虞がある。従来、カウル部内にＥＣＵを配置した技術として、車室とエンジンルームとの間の位置に画成したカウルボックスに防水区画部を設けるものが知られている（例えば、特許文献１参照）。この従来技術では、ＥＣＵが防水区画部内に配置されるため、被水によるＥＣＵの故障の虞を軽減できる。   Vehicle electrical components such as an engine control unit (hereinafter referred to as an ECU) have restrictions on the temperature of the usage environment in order to maintain performance. The engine room has many heat generating parts, so the ambient temperature is high, and there are restrictions on the arrangement of electrical parts. The electrical parts must be installed in a place where the ambient temperature is below the limit temperature. A cowl portion may be selected as an arrangement location of electrical components. The cowl portion is located on the rear side in the vehicle front-rear direction with respect to the engine room, on the front side in the vehicle front-rear direction with respect to the vehicle compartment, and on the lower end portion on the front side in the vehicle front-rear direction with respect to the windshield. Thus, since the cowl part is located in the lower end part of a windshield, the water etc. which transmitted the windshield may permeate in a cowl part. When an electrical component is disposed in the cowl, the electrical component may be damaged by water. 2. Description of the Related Art Conventionally, as a technique for arranging an ECU in a cowl part, a technique in which a waterproof partition part is provided in a cowl box defined at a position between a vehicle compartment and an engine room is known (for example, see Patent Document 1). In this prior art, since the ECU is disposed in the waterproof compartment, the possibility of failure of the ECU due to water exposure can be reduced.

図９および図１０は、カウル部１の上部を車両前後方向後側へ向けて延長させて設けた状態と、カウル部１の下部を車両上下方向下側へ向けて延長させた状態を示す比較例を模式的に示している。カウル部１の上部を車両前後方向後側へ向けて延長させて設けた場合でも、カウル部１の下部を車両上下方向下側へ向けて延長させた場合においても、カウル部１の開口面１Ｂを矢印Ｃから工具を挿入する際にＥＣＵ１０の固定点に工具が届き難いことがわかる。そして、図１０に示すように、ワイパモータ１４などの部品をカウル部１に配置すると、カウル部１の上部の車両前後方向後側へ向けた張り出しや、カウル部１の下部の車両上下方向下側への張り出しが大きくなってしまう。   9 and 10 show a comparison between a state in which the upper portion of the cowl portion 1 is extended toward the rear side in the vehicle longitudinal direction and a state in which the lower portion of the cowl portion 1 is extended downward in the vehicle vertical direction. An example is schematically shown. Even when the upper part of the cowl part 1 is extended toward the rear side in the vehicle front-rear direction, or when the lower part of the cowl part 1 is extended downward in the vehicle vertical direction, the opening surface 1B of the cowl part 1 is provided. It can be seen that when the tool is inserted from the arrow C, it is difficult for the tool to reach the fixed point of the ECU 10. As shown in FIG. 10, when components such as the wiper motor 14 are arranged on the cowl portion 1, the upper portion of the cowl portion 1 projects toward the rear side in the vehicle front-rear direction, and the lower side of the cowl portion 1 in the vehicle vertical direction. The overhang to the will become large.

このような図９に示すような取付構造に対して、本実施の形態の取付構造では、図６に示すように、カウルガーニッシュ８を取り外した状態で、ＥＣＵ１０を取り付けるブラケット９に対して工具が届き易く、目視もし易いという利点がある。図６に示すように、カウルパネル６の前端部６Ａからアンダカウルパネル７の立ち上がり板部７２の上縁までの距離Ｌ２は、第２傾斜部５３の傾斜方向（矢印Ｂ）の長さＬ１よりも長くなるように設定されている。これにより、第２傾斜部５３のブラケット９にＥＣＵ１０を取り付ける際、工具をさらに挿入し易くできる。本実施の形態のようにＥＣＵ１０を取り付けることにより、カウル部１の構造を大きく変更することを防止できる。そして、本実施の形態に係る取付構造では、カウル部１の周囲の他部品のレイアウトに及ぼす影響を低減できる。   In contrast to the mounting structure as shown in FIG. 9, in the mounting structure of the present embodiment, as shown in FIG. 6, the tool is attached to the bracket 9 to which the ECU 10 is mounted with the cowl garnish 8 removed. There is an advantage that it is easy to reach and easy to see. As shown in FIG. 6, the distance L2 from the front end 6A of the cowl panel 6 to the upper edge of the rising plate 72 of the under cowl panel 7 is longer than the length L1 of the second inclined portion 53 in the inclination direction (arrow B). Is also set to be long. Thereby, when attaching ECU10 to the bracket 9 of the 2nd inclination part 53, it can make it easier to insert a tool. By attaching ECU10 like this Embodiment, it can prevent changing the structure of the cowl part 1 largely. In the mounting structure according to the present embodiment, the influence on the layout of other components around the cowl portion 1 can be reduced.
