本実施形態のセンサ配置構造１０は、図１に示すように、車両１の前部に設けられている。センサ配置構造１０は、図２に示すように、レーダ装置１１と、伸縮カバー１２と、フロントグリル１３に一体に形成されたエンブレム１４と、エンブレム１４の裏面１４Ａから車両１の後方に突出する突出部１５と、を備えている。   The sensor arrangement structure 10 of this embodiment is provided in the front part of the vehicle 1 as shown in FIG. As shown in FIG. 2, the sensor arrangement structure 10 includes a radar device 11, an extendable cover 12, an emblem 14 formed integrally with the front grill 13, and a protrusion that protrudes rearward from the rear surface 14 </ b> A of the emblem 14. Part 15.

レーダ装置１１は、車両１の前方の外界に検出範囲が設定されたミリ波レーダなどである。レーダ装置１１は、検出範囲に電磁波のレーダ電波を送信し、各送信波が車両１の外部の物体によって反射されることで生じた反射波を受信する。レーダ装置１１は、送信波および反射波に基づき、例えばレーダ装置１１から外部の物体までの距離、ドップラー効果による外部の物体の相対的な速度、およびレーダ装置１１に対する外部の物体の相対的な位置または方位などに係る検知信号を出力する。レーダ装置１１は、フロントグリル１３と一体に形成されたエンブレム１４の裏面１４Ａに検出範囲上で対面するように配置されている。   The radar device 11 is a millimeter wave radar or the like in which a detection range is set in the external environment in front of the vehicle 1. The radar device 11 transmits a radar wave of an electromagnetic wave to the detection range, and receives a reflected wave generated by each transmission wave being reflected by an object outside the vehicle 1. The radar apparatus 11 is based on the transmitted wave and the reflected wave, for example, the distance from the radar apparatus 11 to an external object, the relative speed of the external object due to the Doppler effect, and the relative position of the external object with respect to the radar apparatus 11. Alternatively, a detection signal related to the direction or the like is output. The radar device 11 is arranged so as to face the back surface 14A of the emblem 14 formed integrally with the front grill 13 on the detection range.

伸縮カバー１２は、図２〜図４に示すように、ゴムなどの材料によって蛇腹構造を有する断面視長方形の筒状に形成されている。伸縮カバー１２の基端１２ａは、ボルトなどの適宜の固定部材（図示略）によって、レーダ装置１１の装置本体１１ａを覆うレドーム１６の周縁部１６ａに密封状態に固定されている。伸縮カバー１２は、レーダ装置１１の検出範囲Ａ内に干渉しないようにして、先端１２ｂをレーダ装置１１の前方に向かい突出させるように配置されている。
伸縮カバー１２は、車両１の前後方向で弾性的に伸縮する蛇腹構造部１２ｃを備えている。蛇腹構造部１２ｃは、レーダ装置１１から前方に向かうことに伴って、伸縮カバー１２の内部空間を拡張傾向に変化させる拡張形状を有している。伸縮カバー１２の先端１２ｂは、レーダ装置１１と対面するように配置されたエンブレム１４の裏面１４Ａに密封状態に接触可能である。これにより伸縮カバー１２は、蛇腹構造部１２ｃの弾性的な伸縮によって先端１２ｂを、エンブレム１４の裏面１４Ａに押し付けるようにして弾性的かつ密封状態に接触させる。 As shown in FIGS. 2 to 4, the extendable cover 12 is formed in a cylindrical shape having a rectangular shape in cross section having a bellows structure made of a material such as rubber. The base end 12a of the telescopic cover 12 is fixed in a sealed state to the peripheral edge portion 16a of the radome 16 that covers the apparatus main body 11a of the radar apparatus 11 by an appropriate fixing member (not shown) such as a bolt. The extendable cover 12 is arranged so that the tip 12 b protrudes forward of the radar device 11 so as not to interfere with the detection range A of the radar device 11.
The extendable cover 12 includes a bellows structure portion 12 c that elastically expands and contracts in the front-rear direction of the vehicle 1. The bellows structure part 12c has an expanded shape that changes the internal space of the extendable cover 12 in an expanding tendency as it moves forward from the radar device 11. The distal end 12b of the extendable cover 12 can contact the back surface 14A of the emblem 14 disposed so as to face the radar device 11 in a sealed state. As a result, the elastic cover 12 is brought into elastic and sealed contact with the tip 12b against the back surface 14A of the emblem 14 by elastic expansion and contraction of the bellows structure portion 12c.

フロントグリル１３と一体に形成されたエンブレム１４は、車両１の前方の外界に対して表面１４Ｂを露出させるとともに、裏面１４Ａによって伸縮カバー１２の先端１２ｂを密封状態に支持するように設けられている。これにより伸縮カバー１２は、エンブレム１４の裏面１４Ａとレーダ装置１１のレドーム１６とによって車両１の前後方向の両側から挟み込まれ、レーダ装置１１を密閉する密閉構造１７を形成する。   The emblem 14 formed integrally with the front grill 13 is provided so that the front surface 14B is exposed to the outside in front of the vehicle 1 and the front end 12b of the extendable cover 12 is supported in a sealed state by the back surface 14A. . As a result, the extendable cover 12 is sandwiched from both sides in the front-rear direction of the vehicle 1 by the back surface 14A of the emblem 14 and the radome 16 of the radar device 11 to form a sealed structure 17 that seals the radar device 11.

エンブレム１４は、密閉構造１７の内部空間１７ａで裏面１４Ａから一体的にレーダ装置１１に向かい突出する突出部１５を備えている。突出部１５は、図５に示すように、伸縮カバー１２の先端１２ｂの形状に沿って、エンブレム１４の裏面１４Ａ上から突出する四角形枠型のリブ形状に形成されている。突出部１５は、内部空間１７ａでレーダ装置１１の検出範囲Ａと干渉しない位置、かつ伸縮カバー１２から離間した位置に配置されている。突出部１５は、エンブレム１４の裏面１４Ａからレーダ装置１１に向かう方向において、蛇腹構造部１２ｃに対応する長さ以下かつ蛇腹構造部１２ｃの１つの山部の長さ以上の突出長さを有している。突出部１５は、伸縮カバー１２が内部空間１７ａの内側に倒れ込むように変形することを防止、または倒れ込みの度合いを規制するために必要とされる伸縮カバー１２から所定位置範囲内に設けられている。   The emblem 14 includes a protrusion 15 that protrudes integrally from the back surface 14 </ b> A toward the radar device 11 in the internal space 17 a of the sealed structure 17. As shown in FIG. 5, the protruding portion 15 is formed in a rectangular frame rib shape protruding from the back surface 14 </ b> A of the emblem 14 along the shape of the tip 12 b of the extendable cover 12. The protruding portion 15 is disposed at a position where it does not interfere with the detection range A of the radar device 11 in the internal space 17 a and at a position separated from the extendable cover 12. The projecting portion 15 has a projecting length equal to or shorter than the length corresponding to the bellows structure portion 12c and not less than the length of one peak portion of the bellows structure portion 12c in the direction from the back surface 14A of the emblem 14 to the radar device 11. ing. The protruding portion 15 is provided within a predetermined position range from the expansion / contraction cover 12 that is necessary for preventing the expansion / contraction cover 12 from being deformed so as to fall into the inner space 17a, or for regulating the degree of the collapse. .

なお、レーダ装置１１の検出範囲上において、フロントグリル１３およびエンブレム１４は、レーダ装置１１の送信波および反射波となる電磁波（例えば、ミリ波など）の透過減衰が抑制された材質により構成されている。   Note that, on the detection range of the radar apparatus 11, the front grill 13 and the emblem 14 are made of a material in which transmission attenuation of electromagnetic waves (for example, millimeter waves) that are transmitted waves and reflected waves of the radar apparatus 11 is suppressed. Yes.

上述したように本実施形態のセンサ配置構造１０によれば、レーダ装置１１に固定された伸縮カバー１２をエンブレム１４の裏面１４Ａに押し付けるようにして、密閉構造１７を容易に形成することができる。これにより密閉構造１７の内部空間１７ａに水などが外部から浸入することを防止することができる。さらに、密閉構造１７の内部空間１７ａの突出部１５によって、伸縮カバー１２が内部空間１７ａの内側に倒れ込むように変形することを防止、または倒れ込みの度合いを規制することができる。これにより伸縮カバー１２が内部空間１７ａの内側に倒れ込むように変形することによって伸縮カバー１２がレーダ装置１１の検出範囲Ａに干渉してしまうことを防止して、検出感度の低下を防ぐことができる。   As described above, according to the sensor arrangement structure 10 of the present embodiment, the sealing structure 17 can be easily formed by pressing the extendable cover 12 fixed to the radar device 11 against the back surface 14A of the emblem 14. As a result, water or the like can be prevented from entering the internal space 17a of the sealed structure 17 from the outside. Further, the protruding portion 15 of the internal space 17a of the sealing structure 17 can prevent the extendable cover 12 from being deformed so as to fall into the inner space 17a, or can regulate the degree of the fall. As a result, the expansion cover 12 can be prevented from interfering with the detection range A of the radar apparatus 11 by deforming the expansion cover 12 so as to fall inside the internal space 17a, thereby preventing a decrease in detection sensitivity. .

さらに、伸縮カバー１２は拡張形状を有しているので、レーダ装置１１の検出範囲Ａが距離の増大に伴って拡張傾向に変化する場合であっても、伸縮カバー１２がレーダ装置１１の検出範囲Ａに干渉してしまうことを防止することができる。さらに、伸縮カバー１２が基端１２ａ側に比べてより大きな形状を有する先端１２ｂ側でエンブレム１４の裏面１４Ａに弾性的に接触するので、伸縮カバー１２とエンブレム１４とを所定の配置関係で容易に接触させることができる。これによりレーダ装置１１および伸縮カバー１２の車体への組み付けを容易にすることができる。
さらに、伸縮カバー１２は、車両１の前後方向で弾性的に伸縮する蛇腹構造部１２ｃを備えるので、伸縮カバー１２の伸縮性および密閉性を向上させることができる。 Further, since the extendable cover 12 has an expanded shape, even if the detection range A of the radar apparatus 11 changes to an expansion tendency as the distance increases, the extendable cover 12 is detected by the radar apparatus 11. Interference with A can be prevented. Further, since the elastic cover 12 is elastically in contact with the back surface 14A of the emblem 14 on the distal end 12b side having a larger shape than the base end 12a side, the elastic cover 12 and the emblem 14 can be easily placed in a predetermined arrangement relationship. Can be contacted. Thereby, the radar apparatus 11 and the expansion / contraction cover 12 can be easily assembled to the vehicle body.
Furthermore, since the extendable cover 12 includes the bellows structure portion 12c that elastically expands and contracts in the front-rear direction of the vehicle 1, the stretchability and the sealing performance of the extendable cover 12 can be improved.

さらに、突出部１５は、内部空間１７ａでレーダ装置１１の検出範囲Ａと干渉しない位置に配置されているので、突出部１５によるレーダ装置１１の検出感度の低下を防ぐことができる。
さらに、突出部１５は、伸縮カバー１２から離間した位置に配置されているので、突出部１５による伸縮カバー１２の変形を防ぐことができる。
さらに、突出部１５は、蛇腹構造部１２ｃに対応する長さ以下かつ蛇腹構造部１２ｃの１つの山部の長さ以上の突出長さを有しているので、伸縮カバー１２が内部空間１７ａの内側に倒れ込むように変形し易い部位で倒れ込みを有効に防止、または規制することができる。しかも、突出部１５の配置に要する費用が嵩むことを防止することができる。 Furthermore, since the protrusion 15 is disposed at a position in the internal space 17a that does not interfere with the detection range A of the radar apparatus 11, it is possible to prevent the detection sensitivity of the radar apparatus 11 from being lowered by the protrusion 15.
Furthermore, since the protrusion part 15 is arrange | positioned in the position spaced apart from the elastic cover 12, the deformation | transformation of the elastic cover 12 by the protrusion part 15 can be prevented.
Further, the projecting portion 15 has a projecting length equal to or shorter than the length corresponding to the bellows structure portion 12c and the length of one peak portion of the bellows structure portion 12c. It is possible to effectively prevent or regulate the fall-down at a portion that is easily deformed so as to fall inside. In addition, it is possible to prevent the cost required for the arrangement of the protrusions 15 from increasing.

なお、上述した実施形態において、突出部１５は伸縮カバー１２の先端１２ｂの形状に沿った枠型の形状を有するとしたが、これに限定されず、伸縮カバー１２の先端１２ｂの形状の少なくとも一部に対応した位置に配置されてもよい。
例えば、図６に示す第１変形例においては、長方形環状の伸縮カバー１２の先端１２ｂに対して、この長方形の各辺の中央部に対応する４つの位置に４つの突出部１５が配置されている。
また、例えば、長方形環状の伸縮カバー１２の先端１２ｂに対して、この長方形の２つの長辺の中央部に対応する２つの位置に２つの突出部１５が配置されてもよい。
また、例えば、長方形環状の伸縮カバー１２の先端１２ｂに対して、この長方形の２つの長辺のうち鉛直方向上方側の長辺の中央部に対応する１つの位置に１つの突出部１５が配置されてもよい。
これらの第１変形例によれば、最低限必要な程度で伸縮カバー１２が内部空間１７ａの内側に倒れ込むことを防止、または規制することができる。 (First modification)
In the above-described embodiment, the projecting portion 15 has a frame shape along the shape of the tip 12b of the stretchable cover 12. However, the present invention is not limited to this, and at least one of the shapes of the tip 12b of the stretchable cover 12 is used. You may arrange | position in the position corresponding to a part.
For example, in the first modification shown in FIG. 6, four protrusions 15 are arranged at four positions corresponding to the center of each side of the rectangle with respect to the tip 12b of the rectangular annular stretchable cover 12. Yes.
For example, two protrusions 15 may be arranged at two positions corresponding to the central portions of the two long sides of the rectangle with respect to the tip 12b of the rectangular annular stretchable cover 12.
