Description

本発明は車両のレーダー装置の取り付け構造に関する。 The present invention relates to a mounting structure for a radar device of a vehicle.

従来から、自車両と先行車両との間の車間距離の検出、あるいは、自車両の前方の歩行者や障害物の検出を行なうためのレーダー装置（ミリ波レーダー装置）を車体前部に搭載した車両が提供されている。
特許文献１には、以下の構成が開示されている。
すなわち、車両前部のフロントバンパーの上部に上下一対のメンバーを車幅方向に沿って配置し、上方のメンバーを下方のメンバーよりも車両後方に配置する。
上下一対のメンバーの中間部に補強部材を架設し、補強部材の上下中間部にレーダ装置を固定し、レーダー装置の前面を下方のメンバーの前面よりも後方に位置させる。
この場合、車両の軽衝突時、他車両のフロントバンパーなどの侵入物が下方のメンバーおよび補強部材の下部に接触するため、衝撃荷重がレーダー装置に入力されることが抑制される。 Conventionally, a radar device (millimeter wave radar device) for detecting an inter-vehicle distance between the own vehicle and a preceding vehicle or detecting a pedestrian or an obstacle in front of the own vehicle is mounted on the front part of the vehicle body. Vehicles are provided.
Patent Document 1 discloses the following configuration.
That is, a pair of upper and lower members are arranged along the vehicle width direction at the upper part of the front bumper at the front of the vehicle, and the upper member is arranged at the rear of the vehicle with respect to the lower member.
A reinforcing member is installed in the middle of the pair of upper and lower members, the radar device is fixed to the upper and lower intermediate parts of the reinforcing member, and the front surface of the radar device is positioned behind the front surface of the lower member.
In this case, at the time of a light collision of the vehicle, an intruding object such as a front bumper of another vehicle comes into contact with the lower member and the lower portion of the reinforcing member, so that the impact load is suppressed from being input to the radar device.

一方、歩行者保護試験のインパクタが車両前部に衝突したときの衝撃吸収性能の向上を図る観点からは、レーダー装置はなるべく車両後方にオフセットした箇所に配置することが好ましい。
上記従来技術では、このような衝撃吸収性能の向上については特に考慮されておらず、改善の余地がある。
しかしながら、レーダー装置を車両後方にオフセットした箇所に配置すると、送信波（レーダー波）の照射範囲内にバンパビームやアッパバーなどの金属部材や金属パネルが位置しないように車体前面部の構造をレイアウトする必要があり、車体前面部のデザインの自由度が制約される不利がある。
また、車体前面部のデザインを優先してレーダー装置を車両前方寄りに配置すると、衝撃吸収性能の向上を図る上で不利となる。
本発明は上記事情に鑑みなされたものであり、その目的は、衝撃吸収性能の向上を図ると共に車体前面部のデザインの自由度を確保する上で有利な車両のレーダー装置の取り付け構造を提供することにある。 On the other hand, from the viewpoint of improving the impact absorption performance when the impactor of the pedestrian protection test collides with the front part of the vehicle, it is preferable to arrange the radar device at a position offset to the rear of the vehicle as much as possible.
In the above-mentioned related art, such an improvement in impact absorption performance is not particularly considered, and there is room for improvement.
However, if the radar device is placed at a position offset to the rear of the vehicle, it is necessary to lay out the structure of the front surface of the vehicle body so that the metal member or metal panel such as bumper beam or upper bar is not located within the irradiation range of the transmitted wave (radar wave). However, there is a disadvantage that the degree of freedom in designing the front surface of the vehicle body is restricted.
Further, if the radar device is arranged closer to the front of the vehicle by giving priority to the design of the front surface of the vehicle body, it is disadvantageous in improving the impact absorbing performance.

The deformation inducing portion 34 is formed to have a lower rigidity than other portions of the bracket 30, and is an area for inducing the deformation of the bracket 30 by the impact received at the front collision of the vehicle 10.
For example, when the impactor of the pedestrian protection test collides with the bracket 30, the deformation inducing portion 34 takes the initiative to deform or breaks first, and the bracket 30 follows the impactor and is displaced rearward, resulting in an impact. Absorb efficiently.

レーダー装置２８は、ケース２８０４を支持する支持部材３２がブラケット３０に取り付けられることで配置されている。
支持部材３２は金属製であり、取り付け板部３２０２と、取り付け板部３２０２の上下から車両１０前方に突出する上下の突出壁３２０４を有している。
支持部材３２は、取り付け板部３２０２の車両１０の後方を向いた後面がブラケット３０の上下方向延在部３０Ｂの上端に溶接により接合され、レーダー装置２８のケース２８０４は、取り付け板部３２０２の車両１０の前方を向いた前面に着脱可能に設けられている。
取り付け板部３２０２の上下高さは、レーダー装置２８のケース２８０４の上下高さよりも大きく、また、取り付け板部３２０２の幅は、レーダー装置２８のケース２８０４の幅よりも大きく、また、上下の突出壁３２０４の突出長さは、レーダー装置２８のケース２８０４の厚さよりも大きな寸法で形成されている。
したがって、本実施の形態では、上下の突出壁３２０４がレーダー装置２８のケース２８０４よりも車両前方に位置している。 The radar device 28 is arranged by attaching a support member 32 that supports the case 2804 to the bracket 30.
The support member 32 is made of metal, and has a mounting plate portion 3202 and upper and lower projecting walls 3204 that project from above and below the mounting plate portion 3202 toward the front of the vehicle 10.
The support member 32 has a rear surface of the mounting plate portion 3202 facing rearward of the vehicle 10 joined by welding to an upper end of the vertically extending portion 30B of the bracket 30, and the case 2804 of the radar device 28 is mounted on the mounting plate portion 3202 of the vehicle. It is removably provided on the front surface of the front face 10.
The vertical height of the mounting plate portion 3202 is larger than the vertical height of the case 2804 of the radar device 28, the width of the mounting plate portion 3202 is larger than the width of the case 2804 of the radar device 28, and the vertical projection. The protruding length of the wall 3204 is formed to be larger than the thickness of the case 2804 of the radar device 28.
Therefore, in the present embodiment, the upper and lower protruding walls 3204 are located in front of the case 2804 of the radar device 28 in the vehicle.

本実施の形態によれば、歩行者保護試験時、インパクタがフロントグリル２６を介してブラケット３０に衝突する。
インパクタがフロントグリル２６を介してブラケット３０に衝突すると、変形誘発部３４が率先して変形し、あるいは、破断され、インパクタに追従してブラケット３０が後方に変位するため、衝撃を効率よく吸収でき、衝撃吸収性能の向上を図る上で有利となる。
また、レーダー装置２８を支持するブラケット３０を利用して衝撃吸収性能の向上を図るので、衝撃を吸収するための特別な部材を設けることなく衝撃吸収性能の向上を図れ、衝撃吸収性能の向上を図るための部品点数の削減化、軽量化を図る上で有利となる。
また、変形誘発部３４は、ブラケット３０の延在方向に間隔をおきレーダー装置２８が支持された箇所を挟んだブラケット３０の２箇所に設けられているので、インパクタがフロントグリル２６を介してブラケット３０に衝突した際に、レーダー装置２８が支持された箇所がより後方に変位し易く、レーダー装置２８の破損を抑制する上でも有利となる。
また、変形誘発部３４を有するブラケット３０を介してレーダー装置２８を配置するので、レーダー装置２８を前部空間Ｓのより前方の箇所に配置でき、車体前面部のデザインの自由度を確保する上で有利となる。 According to the present embodiment, the impactor collides with the bracket 30 via the front grill 26 during the pedestrian protection test.
When the impactor collides with the bracket 30 via the front grill 26, the deformation inducing portion 34 takes the initiative to deform or break, and the bracket 30 is displaced rearward following the impactor, so that the impact can be efficiently absorbed. This is advantageous in improving the shock absorption performance.
In addition, since the bracket 30 that supports the radar device 28 is used to improve the shock absorbing performance, it is possible to improve the shock absorbing performance without providing a special member for absorbing the shock and improve the shock absorbing performance. This is advantageous for reducing the number of parts and weight for the purpose.
Further, since the deformation inducing portions 34 are provided at two positions of the bracket 30 which are spaced from each other in the extending direction of the bracket 30 and sandwich the position where the radar device 28 is supported, the impactor is mounted on the bracket 30 via the front grill 26. When the vehicle collides with 30, the portion where the radar device 28 is supported is more likely to be displaced rearward, which is advantageous in suppressing damage to the radar device 28.
In addition, since the radar device 28 is arranged via the bracket 30 having the deformation inducing portion 34, the radar device 28 can be arranged at a position in front of the front space S, and the degree of freedom in designing the front surface of the vehicle body can be secured. Will be advantageous.

また、本実施の形態では、他車両による前部軽衝突時、レーダー装置２８の車両１０前方に位置する例えばフロントグリル２６が車両１０後方に変位した場合、突出壁３２０４がレーダー装置２８よりも車両１０前方に位置するため、フロントグリル２６が突出壁３２０４に衝突し、突出壁３２０４によりレーダー装置２８が保護される。そのため、レーダー装置２８の破損を抑制する上で有利となる。
また、インパクタがフロントグリル２６を介してブラケット３０に衝突した際も、フロントグリル２６が突出壁３２０４に衝突し、フロントグリル２６がレーダー装置２８に直接衝突することがない。すなわち、突出壁３２０４によりレーダー装置２８が保護され、レーダー装置２８の破損を抑制する上で有利となる。 In addition, in the present embodiment, when a front light collision with another vehicle occurs, for example, when the front grill 26 located in front of the vehicle 10 of the radar device 28 is displaced to the rear of the vehicle 10, the protruding wall 3204 is more vehicle than the radar device 28. The front grille 26 collides with the projecting wall 3204, and the radar device 28 is protected by the projecting wall 3204. Therefore, it is advantageous in suppressing damage to the radar device 28.
Further, even when the impactor collides with the bracket 30 via the front grill 26, the front grill 26 does not collide with the projecting wall 3204 and the front grill 26 does not collide directly with the radar device 28. That is, the protruding wall 3204 protects the radar device 28, which is advantageous in suppressing damage to the radar device 28.

また、本実施の形態では、レーダー装置２８は、ケース２８０４を支持する支持部材３２がブラケット３０に取り付けられることで配置され、突出壁３２０４は、支持部材３２に設けられている。
そのため、レーダー装置２８の取り付けを簡単に行なうえで有利となり、また、突出壁３２０４を簡単に形成でき、コストダウンを図る上で有利となる。 Further, in the present embodiment, the radar device 28 is arranged by attaching the support member 32 that supports the case 2804 to the bracket 30, and the protruding wall 3204 is provided on the support member 32.
Therefore, the radar device 28 can be easily attached, which is advantageous, and the protruding wall 3204 can be easily formed, which is advantageous for cost reduction.

また、本実施の形態では、変形誘発部３４を切り欠き３０１０を用いて構成した場合について説明したが、変形誘発部３４は、例えば、幅を狭くした箇所を設けることで、あるいは、肉厚を薄くした箇所を設けることで構成してもよい。要するに、変形誘発部３４は、他のブラケット３０の箇所に比べて剛性が弱く形成され、衝撃荷重が入力したときに率先して変形し、あるいは、率先して破断される構造であればよく、従来公知の様々な構造が採用可能である。
また、本実施の形態では、ブラケット３０が上下方向に延在している場合について説明したが、ブラケット３０は車幅方向に延在していてもよく、あるいは、上下方向および車幅方向と交差する方向に延在していてもよい。要するにブラケット３０は衝撃を吸収する長さを有していればよく、その延在方向は任意である。 In addition, although the case where the bracket 30 is provided across the upper bar 22 and the bumper beam 14 which are vehicle constituent members has been described in the present embodiment, the vehicle constituent member may be a cross member such as the upper bar 22 or a bumper beam. The structure is not limited to the frame member that forms the frame of the vehicle 10 such as the beam 14. That is, the vehicle constituent member may be a bracket 30 supported by the cross member or the skeleton member, or a case of various components or members such as an inverter supported by the bracket 30.
In addition, although the case where the deformation inducing portion 34 is configured by using the notch 3010 has been described in the present embodiment, the deformation inducing portion 34 is provided with, for example, a portion having a narrow width, or the thickness is reduced. You may comprise by providing the thinned part. In short, the deformation inducing section 34 may be formed so as to have a lower rigidity than the other bracket 30 and to be deformed or to be fractured when an impact load is input. Various conventionally known structures can be adopted.
In addition, although the case where the bracket 30 extends in the vertical direction has been described in the present embodiment, the bracket 30 may extend in the vehicle width direction, or the bracket 30 intersects the vertical direction and the vehicle width direction. It may be extended in the direction. In short, the bracket 30 only needs to have a length that absorbs impact, and its extending direction is arbitrary.

また、本実施の形態では、レーダー装置２８を支持部材３２を介してブラケット３０に取り付けた場合について説明したが、レーダー装置２８をブラケット３０に直接取り付けると共に、ブラケット３０に突出壁３２０４を一体的に設けても良い。ただし、本実施の形態のように、レーダー装置２８を支持する支持部材３２を設け、この支持部材３２に突出壁３２０４を設けると、突出壁３２０４を簡単に形成する上で有利となる。
また、突出壁３２０４は、レーダー装置２８の破損を抑制するものであり、少なくとも１箇所に設ければ良いが、本実施の形態のように突出壁３２０４をレーダー装置２８を挟んで互いに対向する２箇所に設けると、レーダー装置２８の破損を抑制する上で有利となる。その場合の２つの突出壁３２０４の位置は、レーダー装置２８の上下方向の２箇所であってもよく、レーダー装置２８の車幅方向の２箇所であってもよく、あるいは、レーダー装置２８の上下方向および車幅方向に対して交差する方向の２箇所であってもよい。
また、本実施の形態では、レーダー装置２８を前部空間Ｓの前部で車幅方向の中央に配置した場合について説明したが、レーダー装置２８は車幅方向の中間部や端部に配置してもよく、レーダー装置２８の車幅方向の位置は限定されない。また、レーダー装置２８を複数設ける場合には、車幅方向の端部や中間部、中央部などレーダー装置２８の配置箇所は適宜決定される。 In addition, although the case where the radar device 28 is attached to the bracket 30 via the support member 32 has been described in the present embodiment, the radar device 28 is directly attached to the bracket 30 and the protruding wall 3204 is integrally formed on the bracket 30.
