Description

本発明は、ラジエータおよびコンデンサが取り付けられる車両前部のメンバ結合構造に関する。   The present invention relates to a member coupling structure at the front of a vehicle to which a radiator and a capacitor are attached.

車両においては、エンジンルームの前側に、エンジンの冷却水を冷却する冷却装置のラジエータや、車室内を快適な温度状態に維持する空調装置のコンデンサ等を配設している。   In a vehicle, a radiator of a cooling device that cools cooling water of the engine, a condenser of an air conditioner that maintains a comfortable temperature inside the vehicle compartment, and the like are disposed on the front side of the engine room.

車両のエンジンルームの前側には、左右のフロントサイドメンバの前端に支持されてフロントエンドとして枠体が設けられており、この枠体にラジエータおよびコンデンサ等が取り付けられている。この枠体は、上下の車幅方向に配設されたアッパメンバおよびロアメンバの両端部相互間を上下方向に配設されたサポート部材によって連結して構成されている。   On the front side of the engine room of the vehicle, a frame body is provided as a front end supported by the front ends of the left and right front side members, and a radiator, a condenser, and the like are attached to the frame body. The frame body is configured by connecting both end portions of an upper member and a lower member arranged in the vertical vehicle width direction by support members arranged in the vertical direction.

この枠体の下部に配設されるロアメンバは、ロアメンバとサポート部材との結合にＵ字形又はハット形を基本にした断面形状同士の結合をボルトによって上下方向に締結している。しかしながら、ラジエータ等の保持力を高めるために、接続剛性を向上するためには、板厚を厚くする必要があり、結果として重量の増大を招き、かつコストアップとなる。   The lower member disposed in the lower part of the frame body is fastened in the vertical direction by a bolt by connecting a cross-sectional shape based on a U shape or a hat shape to the lower member and the support member. However, in order to increase the holding rigidity of the radiator or the like in order to improve the connection rigidity, it is necessary to increase the plate thickness, resulting in an increase in weight and an increase in cost.

そこで、従来では、ロアメンバの前後に接合するための縦壁部をサポート部材の下端部前後に延出し、一方ロアメンバの両側端部の前後に車幅方向に延出する延出部を設け、この延出部間に段差状の補強部材を接合し、サポート部材の縦壁部で前記ロアメンバの延出部を挟んで接合している。また、ロアメンバの延出部基端部相互間に上方に立設した壁部を設け、この壁部と前記補強部材の縦壁部とで、サポートメンバの側面壁部を挟んで３枚で接合して補強する構造が知られている（特許文献１参照）。   Therefore, conventionally, a vertical wall portion for joining to the front and rear of the lower member is extended to the front and back of the lower end portion of the support member, and an extension portion is provided to extend in the vehicle width direction on the front and rear sides of the lower member. A step-shaped reinforcing member is joined between the extending portions, and the extending portion of the lower member is joined by the vertical wall portion of the support member. In addition, a wall portion standing upward is provided between the base end portions of the extended portions of the lower member, and this wall portion and the vertical wall portion of the reinforcing member are joined by three pieces with the side wall portion of the support member interposed therebetween. A structure for reinforcement is known (see Patent Document 1).

特開２０１０−１４９６０１号公報JP 2010-149601 A

しかしながら、特許文献１に記載の先行技術では、補強部材を必要とし、ロアメンバにも切り欠きや折り曲げが必要で、構成や形状が複雑となり、かつ、ロアメンバの端部が延出部によって、コ字形状が維持されないので、剛性が低下することになる。また、同様にサポート部材も縦壁部によってコ字形状が維持されなくなり、剛性の確保が難しくなる。さらに、精密な補強部材を必要とするので、部品点数の増加となり、コストアップ及び重量増大を招く課題がある。
このように、ラジエータおよびコンデンサ等が取り付けられる枠体の剛性を確保することは、ラジエータおよびコンデンサの懸架を確実なものとするために重要である。また、サイドメンバの先端の振動により発生する車体振動が車室内でこもり音になるため、こもり音対策も必要である。 However, in the prior art described in Patent Document 1, a reinforcing member is required, the lower member also needs to be cut out and bent, the configuration and shape are complicated, and the end of the lower member is extended by the extended portion. Since the shape is not maintained, the rigidity is lowered. Similarly, the U-shape of the support member is not maintained by the vertical wall portion, and it is difficult to ensure rigidity. Further, since a precise reinforcing member is required, the number of parts increases, and there is a problem in that the cost increases and the weight increases.
As described above, it is important to secure the rigidity of the frame body to which the radiator, the capacitor, and the like are attached in order to secure the suspension of the radiator and the capacitor. In addition, since the vehicle body vibration generated by the vibration of the tip of the side member becomes a booming noise in the passenger compartment, it is necessary to take a countermeasure against the booming noise.

本発明は、部品点数の増大を招くことなく、剛性の確保を図ることができる車両前部のメンバ結合構造を提供することを目的とする。   An object of the present invention is to provide a member coupling structure for a vehicle front portion that can ensure rigidity without increasing the number of parts.

本発明は、上記課題を解決するため、車体の前端部上下に車幅方向に配設されたアッパメンバとロアメンバの両端部相互間を、上下方向に配設されたサポート部材によって結合して車両搭載機器を組付ける枠部材を構成した車両前部のメンバ結合構造であって、上記ロアメンバを断面コ字形状の部材を下部側に開口部を配置して用いると共に、前記サポート部材の下端部に、該ロアメンバの上面部と前面部に対向して配置される平面部と縦面部を設け、かつ前記平面部の後端位置から縦面部の下端位置にかけて下方向に延出した側面部を設けると共に該サポート部材の平面部を上記ロアメンバの上面部に締結し、該サポート部材の縦面部を上記ロアメンバの前面部に締結するとともに、前記サポート部材を、車幅方向内側を開口した断面コ字形状の部材で構成し、該サポート部材の下端部内側に前記ロアメンバ上面部に重なる前記平面部を有する補強部材を設け、該サポート部材の前端部に前記補強部材よりも下方向に延設させて前記縦面部を設け、該縦面部の下端部と前記補強部材の後端位置の前記サポート部材の下端部とを結ぶ傾斜ラインに沿って前記サポート部材の側面部の下端部を形成したことにある。
さらに、本発明は、前記サポート部材の少なくとも側面部から縦面部にかけての下端部にフランジ部を設けたことにある。 In order to solve the above problems, the present invention mounts a vehicle by connecting both ends of an upper member and a lower member disposed in the vehicle width direction above and below the front end of the vehicle body by support members disposed in the vertical direction. It is a member coupling structure of the front part of the vehicle that constitutes a frame member for assembling the device, and the lower member is used with a U-shaped member having a U-shaped cross section disposed on the lower side, and at the lower end of the support member, A flat surface portion and a vertical surface portion that are disposed to face the upper surface portion and the front surface portion of the lower member are provided, and a side surface portion that extends downward from a rear end position of the flat surface portion to a lower end position of the vertical surface portion is provided. the flat portion of the support member is fastened to the upper surface of the lower member, the vertical surface portion of the support member as well as fastening the front portion of the lower member, said support member, a U having an open inboard A reinforcing member having the planar portion that overlaps the upper surface of the lower member is provided inside the lower end portion of the support member, and extends downward from the reinforcing member at the front end portion of the support member. The vertical surface portion is provided, and the lower end portion of the side surface portion of the support member is formed along an inclined line connecting the lower end portion of the vertical surface portion and the lower end portion of the support member at the rear end position of the reinforcing member. .
Furthermore, the present invention resides in that a flange portion is provided at a lower end portion from at least a side surface portion to a vertical surface portion of the support member.

A hood lock member 8 for connecting the upper member 5 and the lower member 6 is provided at an intermediate position between the upper member 5 and the lower member 6.

図３および図４は、前記ロアメンバ６と左側のサポート部材７の連結部を拡大して示したものである。前記ロアメンバ６は、前面部６ａと背面部６ｂ相互間を連結する上面部６ｃとで、ハット形に形成されている。
前記サポート部材７は、断面コ字形状の長尺部材の下端部の前面に、前記ロアメンバ６の前面部６ａに対向して配置される縦面部７ａが延出して設けられており、この縦面部７ａと、縦面部７ａよりも下端が短い後部側の縦面部７ｂを連結する側面部７ｃが下辺を前傾斜にして形成されている。後部側の縦面部７ｂはロアメンバ６の上面部６ｃの高さよりも高くなるように縦寸法が設定されている。この後部側の縦面部７ｂから前部側の縦面部７ａを繋ぐ側面部７ｃが設けられている。 3 and 4 are enlarged views of the connecting portion between the lower member 6 and the left support member 7. The lower member 6 is formed in a hat shape with an upper surface portion 6c that connects the front surface portion 6a and the back surface portion 6b.
The support member 7 is provided with a vertical surface portion 7a that is disposed opposite to the front surface portion 6a of the lower member 6 on the front surface of the lower end portion of the long member having a U-shaped cross section. 7a and a side surface portion 7c that connects the vertical surface portion 7b on the rear side whose lower end is shorter than the vertical surface portion 7a are formed with the lower side inclined forward. The vertical dimension of the vertical surface portion 7 b on the rear side is set so as to be higher than the height of the upper surface portion 6 c of the lower member 6. A side surface portion 7c is provided to connect the vertical surface portion 7b on the front side to the vertical surface portion 7b on the rear side.

前記サポート部材７の内側には、後部側の縦面部７ｂの下端よりも下部側に突出するように下端位置が設定されたブラケット９が設けられており、このブラケット９は、下面側の平面部９０を前記ロアメンバ６の上面部６ｃに重なるように対向して配置されている。前記ブラケット９は、前記サポート部材７の縦面部７ａ，７ｂおよび側面部７ｃの内面にそれぞれ接合される折り曲げ部９ａ，９ｂおよび９ｃが設けられている。前記ブラケット９の平面部９０にはボルト孔９１が設けられており、前記ロアメンバ６の上面部６ｃに形成されたボルト孔６１にボルト孔９１を合わせてボルト１０およびナット１１を介して鉛直方向に締結されている。また、前記サポート部材７の前部側の縦面部７ａには、ボルト孔７１が形成されており、前記ロアメンバ６の前面部６ａに形成されたボルト孔６２に合わせて、ボルト１２およびナット１３を介して前後方向に締結されている。   Inside the support member 7 is provided a bracket 9 whose lower end position is set so as to protrude below the lower end of the vertical surface portion 7b on the rear side. The bracket 9 is a flat portion on the lower surface side. 90 is arranged so as to oppose the upper surface portion 6c of the lower member 6. The bracket 9 is provided with bent portions 9a, 9b and 9c to be joined to the inner surfaces of the vertical surface portions 7a and 7b and the side surface portion 7c of the support member 7, respectively. A bolt hole 91 is provided in the flat portion 90 of the bracket 9, and the bolt hole 91 is aligned with the bolt hole 61 formed in the upper surface portion 6 c of the lower member 6 in the vertical direction via the bolt 10 and the nut 11. It is concluded. A bolt hole 71 is formed in the vertical surface portion 7 a on the front side of the support member 7, and the bolt 12 and the nut 13 are attached to the bolt hole 62 formed in the front surface portion 6 a of the lower member 6. It is fastened in the front-rear direction.

前記サポート部材７は前後の縦面部７ａ，７ｂ相互を繋ぐ側面部７ｃの下片を後ろ側の縦面部７ｂから前側の縦面部７ａにかけて前下がりの傾斜面７２に形成されており、これら縦面部７ａ，７ｂおよび側面部７ｃの下端部に外側に向けてフランジ部７３が連続するように形成されている。前記サポート部材７の側面部７ｃ下端の傾斜面７２の角度θは、ボルト１０，１２の中心を結ぶラインＬの角度αよりも大きく設定し、傾斜面７２がラインＬを横切るように配置されている。ラインＬはロアメンバ６とブラケット９の接合面を貫くように構成されていることから回転するような変形を生じない。   The support member 7 is formed as an inclined surface 72 having a front lowering from the lower piece of the side surface portion 7c connecting the front and rear vertical surface portions 7a and 7b to the front vertical surface portion 7a from the rear vertical surface portion 7b. A flange portion 73 is formed so as to continue outward at the lower ends of 7a and 7b and the side surface portion 7c. The angle θ of the inclined surface 72 at the lower end of the side surface portion 7c of the support member 7 is set larger than the angle α of the line L connecting the centers of the bolts 10 and 12, and the inclined surface 72 is arranged so as to cross the line L. Yes. Since the line L is configured to penetrate through the joint surface between the lower member 6 and the bracket 9, the line L is not deformed to rotate.

上記構成によると、前記サポート部材７とロアメンバ６の結合において、前記サポート部材７のコ字形状部の内側に前記ブラケット９をスポット溶接により接合し、このブラケット９の平面部９０を前記ロアメンバ６の上面部６ｃに対向するように配置して組付ける。そして、前記ブラケット９の平面部９０のボルト孔９１を前記ロアメンバ６の上面部６ｃのボルト孔６１に合わせてボルト孔６１とボルト孔９１にボルト１０を通して前記ブラケット９の平面部９０の内側に溶接等で組付けられたナット１１にボルト１０を螺合して締結される。   According to the above configuration, when the support member 7 and the lower member 6 are coupled, the bracket 9 is joined to the inside of the U-shaped portion of the support member 7 by spot welding, and the flat portion 90 of the bracket 9 is connected to the lower member 6. Arrange it so as to face the upper surface part 6c. Then, the bolt hole 91 of the flat surface portion 90 of the bracket 9 is aligned with the bolt hole 61 of the upper surface portion 6 c of the lower member 6, and the bolt 10 is passed through the bolt hole 61 and the bolt hole 91 and welded to the inside of the flat surface portion 90 of the bracket 9. The bolts 10 are screwed onto the nuts 11 that are assembled by, for example, fastening.

このとき、前記ロアメンバ６の前面部６ａには、前記サポート部材７の縦面部７ａが配置されており、縦面部７ａに設けられたボルト孔７１が前記ロアメンバ６の前面部６ａに設けられたボルト孔６２に配置される。こうして、ボルト孔７１とボルト孔６２にボルト１２を通して前記ロアメンバ６の前面部６ａの内側に溶接等で取り付けられたナット１３に螺合して前記サポート部材７の縦面部７ａとロアメンバ６の前面部６ａを締結する。   At this time, the front surface portion 6 a of the lower member 6 is provided with the vertical surface portion 7 a of the support member 7, and a bolt hole 71 provided in the vertical surface portion 7 a is a bolt provided in the front surface portion 6 a of the lower member 6. Arranged in the hole 62. Thus, the bolts 71 and 62 are bolted through the bolts 12 and screwed into the nuts 13 attached to the inner side of the front surface portion 6a of the lower member 6 by welding or the like. 6a is fastened.

こうして、上記実施の形態によると前記ロアメンバ６の両側を左右のサポート部材７によって鉛直方向と前後方向からボルト締めにより結合するので、剛性の向上を図ることができる。通常、パネルの剛性は、面直方向よりも面内方向のほうが高いので、ボルト締結の一つを横方向の締結を採用することで剛性の高い面内方向で力を受けるようになり、接続剛性が向上する。上記実施の形態によるボルト位置を通る直線が、接合面を貫いているため、各々のボルト軸を中心として回転するような変形を生じない。また、前記サポート部材７の側面部７ｃ下端の傾斜面７２の角度θは、ボルト１０，１２の中心を結ぶラインＬの角度αよりも大きく設定し、傾斜面７２がラインＬを横切るように配置されている。ラインＬはロアメンバ６とブラケット９の接合面を貫くように構成されていることから、各々のボルト軸を中心として回転するような変形を生じない。このように、横方向の接続部に隣接して形状稜線が通っているため、シンプルな形状でありながら、車体への結合剛性が高い。   In this way, according to the above embodiment, both sides of the lower member 6 are coupled by bolting from the vertical direction and the front-rear direction by the left and right support members 7, so that the rigidity can be improved. Normally, the rigidity of the panel is higher in the in-plane direction than in the in-plane direction. By adopting one of the bolt fastenings in the lateral direction, it will receive a force in the in-plane direction with high rigidity. Stiffness is improved. Since the straight line passing through the bolt position according to the above embodiment penetrates the joint surface, deformation that rotates around each bolt axis does not occur. Further, the angle θ of the inclined surface 72 at the lower end of the side surface portion 7c of the support member 7 is set to be larger than the angle α of the line L connecting the centers of the bolts 10 and 12, and the inclined surface 72 crosses the line L. Has been. Since the line L is configured to penetrate the joint surface between the lower member 6 and the bracket 9, there is no deformation that rotates around each bolt shaft. Thus, since the shape ridge line passes adjacent to the connecting portion in the horizontal direction, the rigidity of the coupling to the vehicle body is high while having a simple shape.

前記サポート部材７は前後の縦面部７ａ，７ｂ相互を繋ぐ側面部７ｃの下片を後ろ側の縦面部７ｂから前側の縦面部７ａにかけて前下がりの傾斜面７２に形成されているので、この後部側の縦面部７ｂから前部側の縦面部７ａを繋ぐ側面部７ｃによって、前記ロアメンバ６とサポート部材７を組み付ける２つのボルト間を結ぶ剛性を向上することができる。また、これら縦面部７ａ，７ｂおよび側面部７ｃの下端部に外側に向けてフランジ部７３が連続するように形成されているので剛性の向上を図ることができる。   Since the support member 7 is formed on an inclined surface 72 that is inclined downward from the rear vertical surface portion 7b to the front vertical surface portion 7a, the lower piece of the side surface portion 7c that connects the front and rear vertical surface portions 7a and 7b to each other. By the side surface portion 7c that connects the vertical surface portion 7b on the side to the vertical surface portion 7a on the front side, it is possible to improve the rigidity connecting the two bolts that assemble the lower member 6 and the support member 7. Further, since the flange portion 73 is formed so as to continue outward at the lower end portions of the vertical surface portions 7a and 7b and the side surface portion 7c, the rigidity can be improved.
