Description

本発明は、車両用外装部品に関する。 The present invention relates to exterior parts for vehicles.

従来、車載レーダー装置の電波発射方向の前方に設けられる車両用外装部品が知られている。特許文献1では、降雪時でもミリ波を利用して車間距離や障害物との距離を計測可能なように、車両用装飾部品に融雪機能を付加している。具体的には、車両用装飾部品に雪が付着しても、その雪は加熱シートにおける線状のヒーターから伝わる熱によって溶かされるようになっている。 Conventionally, vehicle exterior parts provided in front of an in-vehicle radar device in a radio wave emitting direction are known. In Patent Document 1, a snow melting function is added to decorative parts for vehicles so that the distance between vehicles and the distance to obstacles can be measured by using millimeter waves even when it snows. Specifically, even if snow adheres to the decorative parts for vehicles, the snow is melted by the heat transmitted from the linear heater in the heating sheet.

特許第6665691号公報Japanese Patent No. 6665691

特許文献1の車両用装飾部品では、加熱シートは、装飾本体部に一体に設けられた主要部と、主要部から装飾本体部の面方向の外側に向けて当該装飾本体部の外部へ延びる接続部とから構成されている。ヒーターの両端部の受電用の接続端子は、加熱シートの接続部に形成されている。 In the vehicle decorative parts of Patent Document 1, the heating sheet is connected to the main portion integrally provided in the decorative main body portion and to the outside of the decorative main body portion from the main portion toward the outside in the surface direction of the decorative main body portion. It is composed of parts. The connection terminals for receiving power at both ends of the heater are formed at the connection portions of the heating sheet.

これに対し、本発明者は、受電用の接続端子をヒーターとは別部材から構成しつつ、ヒーターの背後(すなわち、ヒーターに対して車両内側)に設けることを考えている。この場合、特許文献1の装飾本体部に対応する樹脂部材に受電用の接続端子をインサートすることが考えられる。しかし、樹脂部材を形成した後では、ヒーターと受電用の接続端子との接触不良が起こった場合に調整が不可能になるという問題がある。 On the other hand, the present inventor considers that the connection terminal for receiving power is provided behind the heater (that is, inside the vehicle with respect to the heater) while being composed of a member separate from the heater. In this case, it is conceivable to insert a power receiving connection terminal into the resin member corresponding to the decorative main body portion of Patent Document 1. However, after forming the resin member, there is a problem that adjustment becomes impossible when a poor contact between the heater and the connection terminal for receiving power occurs.

本発明は、このような点に鑑みて創作されたものであり、その目的は、ヒーターの接触不良が抑制された車両用外装品を提供することにある。 The present invention has been created in view of these respects, and an object of the present invention is to provide an exterior product for a vehicle in which poor contact of a heater is suppressed.

本発明は、車載レーダー装置の電波発射方向の前方に設置される車両用外装部品であって、車両外側に配置されるアウター部と、アウター部に対して車両内側に設けられたヒーター部と、少なくとも一部がヒーター部に対して車両内側に設けられ、アウター部およびヒーター部に接している樹脂製のベース部と、ヒーター部に対して車両内側に設けられ、一部がベース部にインサートされた金属製の接続部材と、接続部材に電気的に接続された金属端子を有するケーブルと、ベース部に固定され、ケーブルを保持しているケーブル保持部材と、を備える。ケーブル保持部材は、接続部材をヒーター部に向けて押圧している。 The present invention is an exterior component for a vehicle installed in front of an in-vehicle radar device in a radio wave emitting direction, and has an outer portion arranged on the outside of the vehicle, a heater portion provided on the inside of the vehicle with respect to the outer portion, and a heater portion. At least a part is provided inside the vehicle with respect to the heater part, a resin base part in contact with the outer part and the heater part, and a part is provided inside the vehicle with respect to the heater part, and a part is inserted into the base part. It includes a metal connecting member, a cable having a metal terminal electrically connected to the connecting member, and a cable holding member fixed to a base portion and holding the cable. The cable holding member presses the connecting member toward the heater portion.

このように接続部材がケーブル保持部材によりヒーター部に向けて押圧されることで、ヒーター部と接続部材との接触不良が起きにくい。また、ケーブル保持部材と接続部材との押圧方向のサイズを調整することで比較的容易に押圧力を調整できる。 By pressing the connecting member toward the heater portion by the cable holding member in this way, poor contact between the heater portion and the connecting member is unlikely to occur. Further, the pressing force can be adjusted relatively easily by adjusting the size of the cable holding member and the connecting member in the pressing direction.

次に、装飾部品10の製造方法について図6~図9、および図4を参照して説明する。先ず図6に示すように、透明樹脂フィルム35上に不透明部22、ヒーター部30および加飾部23が形成される。続いて図7に示すように透明樹脂フィルム35が金型80にセットされ、透明部21がインサート成形される。このとき、金型80の形状に沿って透明部21に凹部24が形成される。他の実施形態では、金型80の開き方向は左右方向に限らず、例えば上下方向等の他の方向であってもよい。また、他の実施形態では、透明部21の成形後に加飾部23が形成されてもよい。 Next, a method of manufacturing the decorative part 10 will be described with reference to FIGS. 6 to 9 and FIG. First, as shown in FIG. 6, an opaque portion 22, a heater portion 30, and a decorative portion 23 are formed on the transparent resin film 35. Subsequently, as shown in FIG. 7, the transparent resin film 35 is set in the mold 80, and the transparent portion 21 is insert-molded. At this time, the recess 24 is formed in the transparent portion 21 along the shape of the mold 80. In another embodiment, the opening direction of the mold 80 is not limited to the left-right direction, and may be another direction such as a vertical direction. Further, in another embodiment, the decorative portion 23 may be formed after the transparent portion 21 is molded.

続いて図8に示すように透明部21の外周から飛び出している透明樹脂フィルム35が不透明部22、加飾部23およびヒーター部30共にカットされ、透明部21にハードコート層25が形成される。続いて図9に示すように、ヒーター部30等込みの透明部21が金型85にセットされ、接続部材50が所定位置に配置された状態で、ベース部40がインサート成形される。他の実施形態では、金型85の開き方向は上下方向に限らず、例えば左右方向等の他の方向であってもよい。また、他の実施形態では、ベース部40は、インサート成形に限らず、例えば接着または溶着等によりアウター部20およびヒーター部30に一体に設けられてもよい。 Subsequently, as shown in FIG. 8, the transparent resin film 35 protruding from the outer periphery of the transparent portion 21 is cut together with the opaque portion 22, the decorative portion 23, and the heater portion 30, and the hard coat layer 25 is formed on the transparent portion 21. .. Subsequently, as shown in FIG. 9, the transparent portion 21 including the heater portion 30 and the like is set in the mold 85, and the base portion 40 is insert-molded with the connecting member 50 arranged at a predetermined position. In another embodiment, the opening direction of the mold 85 is not limited to the vertical direction, and may be another direction such as the left-right direction. Further, in another embodiment, the base portion 40 is not limited to insert molding, and may be integrally provided on the outer portion 20 and the heater portion 30 by, for example, adhesion or welding.

続いて図4に示すように、スクリュー75によりケーブル保持部材70がベース部40に固定される。このとき、ケーブル保持部材70の押圧部73が接続部材50の被押圧部53に当接した状態でスクリュー75が締め付けられることで、接続部材50をヒーター部30に押し付ける力が加えられる。 Subsequently, as shown in FIG. 4, the cable holding member 70 is fixed to the base portion 40 by the screw 75. At this time, the screw 75 is tightened while the pressing portion 73 of the cable holding member 70 is in contact with the pressed portion 53 of the connecting member 50, so that a force for pressing the connecting member 50 against the heater portion 30 is applied.

(効果)
以上説明したように、ミリ波レーダー装置92の電波発射方向の前方に設置される装飾部品10は、車両外側に配置されるアウター部20と、アウター部20に対して車両内側に設けられたヒーター部30と、少なくとも一部がヒーター部30に対して車両内側に設けられ、アウター部20およびヒーター部30に接している樹脂製のベース部40と、ヒーター部30に対して車両内側に設けられ、一部がベース部40にインサートされた金属製の接続部材50と、接続部材50に電気的に接続された金属端子61を有するケーブル60と、ベース部40に固定され、ケーブル60を保持しているケーブル保持部材70と、を備える。ケーブル保持部材70は、接続部材50をヒーター部30に向けて押圧している。
(effect)
As described above, the decorative parts 10 installed in front of the millimeter-wave radar device 92 in the radio wave emitting direction include an outer portion 20 arranged on the outside of the vehicle and a heater provided on the inside of the vehicle with respect to the outer portion 20. The portion 30 and at least a part thereof are provided inside the vehicle with respect to the heater portion 30, and are provided inside the vehicle with respect to the outer portion 20 and the resin base portion 40 in contact with the heater portion 30 and the heater portion 30.

The cable holding member 70 is provided. The cable holding member 70 presses the connecting member 50 toward the heater portion 30.

このように接続部材50がケーブル保持部材70によりヒーター部30に向けて押圧されることで、ヒーター部30と接続部材50との接触不良が起きにくい。また、ケーブル保持部材70と接続部材50との押圧方向のサイズを調整することで比較的容易に押圧力を調整できる。 By pressing the connecting member 50 toward the heater portion 30 by the cable holding member 70 in this way, poor contact between the heater portion 30 and the connecting member 50 is unlikely to occur. Further, the pressing force can be adjusted relatively easily by adjusting the size of the cable holding member 70 and the connecting member 50 in the pressing direction.

また第1実施形態では、接続部材50は、ヒーター部30と平行な板状に形成され、ベース部40にインサートされたヒーター接続部51と、ヒーター接続部51からベース部40外に突き出すように形成され、金属端子61に接触しているケーブル接続部52と、ヒーター接続部51のうちケーブル接続部52とは異なる箇所からベース部40外に露出するように形成され、ケーブル保持部材70に押圧されている被押圧部53とを有する。このようにケーブル接続部52と被押圧部53とを別に設けることで、ケーブル接続部52および被押圧部53をそれぞれの機能に適した形状とすることができる。被押圧部53の突出長さを比較的短くすることで、押圧力に耐えうる強度を確保できる。 Further, in the first embodiment, the connecting member 50 is formed in a plate shape parallel to the heater portion 30 so as to protrude from the heater connecting portion 51 inserted into the base portion 40 and the heater connecting portion 51 to the outside of the base portion 40. The cable connection portion 52 formed and in contact with the metal terminal 61 is formed so as to be exposed to the outside of the base portion 40 from a portion of the heater connection portion 51 different from the cable connection portion 52, and is pressed against the cable holding member 70. It has a pressed portion 53 which is pressed. By separately providing the cable connecting portion 52 and the pressed portion 53 in this way, the cable connecting portion 52 and the pressed portion 53 can be formed into a shape suitable for each function. By making the protruding length of the pressed portion 53 relatively short, it is possible to secure the strength that can withstand the pressing force.

また第1実施形態では、アウター部20は、透明部21と、透明部21に対して車両内側に設けられた不透明部22および加飾部23とを有する。接続部材50は、車両外側から見たとき不透明部22の背後に完全に隠れるように配置されている。これにより、接続部材が車両外側から見えなくなっている。 Further, in the first embodiment, the outer portion 20 has a transparent portion 21, an opaque portion 22 provided inside the vehicle with respect to the transparent portion 21, and a decorative portion 23. The connecting member 50 is arranged so as to be completely hidden behind the opaque portion 22 when viewed from the outside of the vehicle. As a result, the connecting member cannot be seen from the outside of the vehicle.

(第2実施形態)
第2実施形態では、図10、図11に示すように、接続部材50は、第1実施形態におけるケーブル接続部52および被押圧部53に代えて、ケーブル接続部522を有する。ケーブル接続部522は、ヒーター接続部51からベース部40外に突き出すように形成され、金属端子612に接触するとともにケーブル保持部材70に押圧されている。つまり第2実施形態では、1つの突出部であるケーブル接続部522が、金属端子612に接続する部分と押圧部73に押圧される部分とを兼ねている。
(Second Embodiment)
In the second embodiment, as shown in FIGS. 10 and 11, the connecting member 50 has a cable connecting portion 522 instead of the cable connecting portion 52 and the pressed portion 53 in the first embodiment. The cable connection portion 522 is formed so as to protrude from the heater connection portion 51 to the outside of the base portion 40, and is in contact with the metal terminal 612 and is pressed against the cable holding member 70. That is, in the second embodiment, the cable connecting portion 522, which is one protruding portion, serves both as a portion connected to the metal terminal 612 and a portion pressed by the pressing portion 73.

具体的には、ケーブル接続部522は円筒状突起であり、比較的肉厚に形成されている。金属端子612は、ケーブル接続部522の内側に挿入されたクリップ形状であり、弾性復帰力により外側に押し広げられることでケーブル接続部522の内壁に接触している。 Specifically, the cable connection portion 522 is a cylindrical protrusion and is formed to be relatively thick. The metal terminal 612 has a clip shape inserted inside the cable connection portion 522, and is in contact with the inner wall of the cable connection portion 522 by being pushed outward by the elastic return force.

押圧部732は、保持部71から接続部材50側に突き出す突出部からなり、その内壁に形成された段差面により被押圧部53を押圧している。 The pressing portion 732 is composed of a protruding portion protruding from the holding portion 71 toward the connecting member 50, and presses the pressed portion 53 by a stepped surface formed on the inner wall thereof.

このようなケーブル接続部522を有する接続部材50を用いてもよい。それでも接続部材50がケーブル保持部材70によりヒーター部30に向けて押圧されることで、第1実施形態と同様の効果を得ることができる。 A connecting member 50 having such a cable connecting portion 522 may be used. Nevertheless, the connection member 50 is pressed toward the heater portion 30 by the cable holding member 70, so that the same effect as that of the first embodiment can be obtained.

(他の実施形態)
他の実施形態では、接続部材のヒーター接続部の板厚方向のシルエットは、矩形に限らず、例えば円形等の他の形状であってもよい。また、被押圧部は、直線状に延出する形状に限らず、曲線状に延出する形状であってもよい。ヒーター接続部の板厚方向のシルエットが円形である場合、被押圧部は、ヒーター接続部の周囲に沿って円弧状に延出する形状であってもよい。また、被押圧部の数は、2つに限らず、1つ、または3つ以上であってもよい。

本発明は、上述した実施形態に限定されるものではなく、発明の趣旨を逸脱しない範囲で種々の形態で実施可能である。 The present invention is not limited to the above-described embodiment, and can be implemented in various forms without departing from the spirit of the invention.

以下、参考形態について説明する。図12に示す装飾部品100は、アウター部205と、ベース部405と、ベース部405に対して車両内側に設けられたヒーター部305と、導線605に接続され、弾性および導電性をもつ接着剤625によりヒーター部305に固定された金属端子615とを備える。 Hereinafter, the reference form will be described. The decorative component 100 shown in FIG. 12 is an adhesive having elasticity and conductivity connected to an outer portion 205, a base portion 405, a heater portion 305 provided inside the vehicle with respect to the base portion 405, and a conducting wire 605. It is provided with a metal terminal 615 fixed to the heater portion 305 by 625.

ベース部405は、当該ベース部405から突出してヒーター部305および金属端子615を貫通するボス455を有する。金属端子615と配線部との位置精度を高めるため、ボス455の先端を溶融させてつぶすことで、接着剤625が固まるまで形状保持させる。 The base portion 405 has a boss 455 that protrudes from the base portion 405 and penetrates the heater portion 305 and the metal terminal 615. In order to improve the positional accuracy between the metal terminal 615 and the wiring portion, the tip of the boss 455 is melted and crushed to maintain the shape until the adhesive 625 hardens.

ベース部405は、当該ベース部405から突出して金属端子615に当接する高さ調整用リブ465を有する。これにより、金属端子615とヒーター部305との間隔が一定になるため、量産時に接着剤625の厚みがばらつくことによる抵抗値の変化が少なくなる。また、金属端子615とヒーター部305とが直接接触することを避けることで、外部から伝わる振動により金属端子615が振動してもヒーター部305に損傷を与えない。 The base portion 405 has a height adjusting rib 465 that protrudes from the base portion 405 and abuts on the metal terminal 615. As a result, the distance between the metal terminal 615 and the heater portion 305 becomes constant, so that the change in resistance value due to the variation in the thickness of the adhesive 625 during mass production is reduced. Further, by avoiding direct contact between the metal terminal 615 and the heater portion 305, even if the metal terminal 615 vibrates due to vibration transmitted from the outside, the heater portion 305 is not damaged.

図12に示す参考形態における接着剤625および金属端子615に代えて、金属端子をコネクタによりベース部に固定するように構成してもよい。この場合、金属端子とヒーター部は、両者間に金属製バネを設けることにより電気的に接続するバヨネット構造を採用し得る。 Instead of the adhesive 625 and the metal terminal 615 in the reference embodiment shown in FIG. 12, the metal terminal may be configured to be fixed to the base portion by a connector. In this case, the metal terminal and the heater portion may adopt a bayonet structure that is electrically connected by providing a metal spring between them.
