Description

本発明は、車両正面の衝撃吸収を行うサイドフレームの前周壁に部品取付ブラケットを設けた車体前部構造に関するものである。   The present invention relates to a vehicle body front portion structure in which a component mounting bracket is provided on a front peripheral wall of a side frame that absorbs a shock in front of a vehicle.

車体前部構造には、前輪の上方のフロントフェンダを支持するフェンダ支持部材が、車両正面から車室まで延びるサイドフレーム（サイドメンバー）に取付けられ、正面からの衝撃を主にフェンダ支持部材で吸収できるようにしたものがある（例えば、特許文献１参照。）。
特許第３７９１０７１号公報（第４頁、図１） A fender support member that supports the front fender above the front wheels is attached to the side frame (side member) that extends from the front of the vehicle to the passenger compartment, and the impact from the front is mainly absorbed by the fender support member. There is one that can be made (for example, see Patent Document 1).
Japanese Patent No. 3791071 (page 4, FIG. 1)

しかし、特許文献１のようなサイドフレーム（サイドメンバー）の前部にさらに部材を取付けてフェンダ支持部材を支持する必要がある構造では、衝撃吸収するサイドフレームの前周壁が拘束されて、サイドフレームの衝撃吸収の変形を妨げるという問題がある。   However, in a structure in which a member is further attached to the front portion of the side frame (side member) as in Patent Document 1 and the fender support member needs to be supported, the front peripheral wall of the side frame that absorbs the shock is restrained, and the side frame There is a problem of preventing deformation of shock absorption.

本発明は、サイドフレームの前周壁に部品取付ブラケットを取付けても、サイドフレームの衝撃吸収を妨げず、サイドフレームの衝撃吸収を高めた車体前部構造を提供することを課題とする。   An object of the present invention is to provide a vehicle body front structure that does not hinder the shock absorption of the side frame even when the component mounting bracket is attached to the front peripheral wall of the side frame, and that increases the shock absorption of the side frame.

請求項１に係る発明は、車両前部から車室まで延びて正面衝突のときに車両後方へ向かって座屈することで衝撃を吸収するサイドフレームと、サイドフレームの前周壁に取付けられている部品取付ブラケットと、を備えた車体前部構造において、部品取付ブラケットは、サイドフレームの長手方向に直交する断面に平行に溶接軸を設けた接合部を備えていることを特徴とする。   The invention according to claim 1 includes a side frame that extends from the front of the vehicle to the passenger compartment and buckles toward the rear of the vehicle in the event of a frontal collision to absorb shocks, and a component that is attached to the front peripheral wall of the side frame. In the vehicle body front part structure including the mounting bracket, the component mounting bracket includes a joint portion provided with a welding shaft in parallel to a cross section perpendicular to the longitudinal direction of the side frame.

請求項２に係る発明は、接合部は、サイドフレームに平行に延ばして面接触していることを特徴とする。   The invention according to claim 2 is characterized in that the joint extends in parallel with the side frame and is in surface contact.

請求項１に係る発明では、正面衝突のときに座屈することで衝撃を吸収するサイドフレームと、サイドフレームの前周壁に取付けられている部品取付ブラケットと、を備え、部品取付ブラケットは、サイドフレームの長手方向に直交する断面に平行に溶接軸を設けた接合部を備えているので、部品取付ブラケットは、サイドフレームの座屈（潰れ）を妨げないという利点がある。その結果、サイドフレームは部品取付ブラケットに拘束されずに部品取付ブラケットとともに車両後方へ向かって潰れ続けることができ、部品取付ブラケットはサイドフレームの衝撃吸収を高めることができる。   The invention according to claim 1 includes a side frame that absorbs an impact by buckling at the time of a frontal collision, and a component mounting bracket that is mounted on the front peripheral wall of the side frame. Since the joint part provided with the welding shaft in parallel with the cross section orthogonal to the longitudinal direction of the part is provided, the component mounting bracket has an advantage of not preventing the side frame from buckling (collapse). As a result, the side frame can continue to be crushed toward the rear of the vehicle together with the component mounting bracket without being constrained by the component mounting bracket, and the component mounting bracket can enhance shock absorption of the side frame.

また、溶接軸線は接合部を所望の溶接長で溶接したビードのものであり、つまり、接合部の溶接長を長くすることができ、接合部の溶接強度を高めることができる。同時に、溶接のビードはサイドフレームの座屈（潰れ）を妨げない。従って、サイドフレームの衝撃吸収を高めることができる。   Further, the weld axis is a bead in which the joint is welded with a desired weld length, that is, the weld length of the joint can be increased, and the weld strength of the joint can be increased. At the same time, the weld bead does not prevent the side frame from buckling. Therefore, the shock absorption of the side frame can be enhanced.

請求項２に係る発明では、接合部は、サイドフレームに面接触しているので、放熱面積が大きくなり、溶接軸線を有している溶接ビードを施す際の熱を逃がすことができ、接合部に生じる熱影響を抑制することができる。   In the invention according to claim 2, since the joint portion is in surface contact with the side frame, the heat radiation area is increased, and the heat at the time of applying the weld bead having the welding axis can be released. It is possible to suppress the thermal effect generated in the process.

図６は、図５の６矢視図である。図３、図５を併用して説明する。
第１部品取付ブラケット２１は、具体的には、サイドフレーム１４の外辺部４９から外辺部４９に平行に距離Ｂ１だけ離して配置している第１乖離平板部９１が形成され、第１乖離平板部９１から直交してサイドフレーム１４の外辺部４９まで延びて、外辺部４９に面接触し且つ、第１乖離平板部９１の外方（矢印ａ６の方向）に延びている第１接合部８２が形成され、第１接合部８２の縁が第１縁開先部９２をなし、第１縁開先部９２に溶接のビード９３を施すことでサイドフレーム１４の外辺部４９に接合されている。さらに、第１乖離平板部９１の他方に支持部材（フェンダフレーム）８４の第１フレーム８５を嵌合している嵌合接合部９４が形成され、嵌合接合部９４の縁が第２縁開先９５をなし溶接で接合している。ビード９３が溶接軸８１を有している。 FIG. 6 is a view taken in the direction of arrow 6 in FIG.

Specifically, the first component mounting bracket 21 is formed with a first detaching flat plate portion 91 that is arranged in parallel with the outer side portion 49 from the outer side portion 49 of the side frame 14 by a distance B1. It extends perpendicularly from the divergence flat plate portion 91 to the outer side portion 49 of the side frame 14, is in surface contact with the outer side portion 49, and extends outward (in the direction of arrow a6) from the first divergence flat plate portion 91. 1 joint portion 82 is formed, the edge of the first joint portion 82 forms a first edge groove portion 92, and a weld bead 93 is applied to the first edge groove portion 92, whereby an outer edge portion 49 of the side frame 14. It is joined to. Further, a fitting joint portion 94 is formed on the other side of the first separation flat plate portion 91 to fit the first frame 85 of the support member (fender frame) 84, and the edge of the fitting joint portion 94 is opened to the second edge. The tip 95 is joined and welded. The bead 93 has a welding shaft 81.

「第１接合部８２は、サイドフレーム１４に平行に延ばして面接触している」とは、第１乖離平板部９１からサイドフレーム１４まで延びる脚部９７が形成され、脚部９７に直交させ且つ、外辺部４９に平行に脚当接部９８が第１接合部８２の板厚ｔ１の約１．６倍の長さＬで形成されて、脚当接部９８が面接触している。   “The first joint portion 82 extends in parallel with the side frame 14 and is in surface contact” means that the leg portion 97 extending from the first separation flat plate portion 91 to the side frame 14 is formed and orthogonal to the leg portion 97. In addition, the leg contact portion 98 is formed in parallel with the outer side portion 49 with a length L that is approximately 1.6 times the plate thickness t1 of the first joint portion 82, and the leg contact portion 98 is in surface contact. .

第１乖離平板部９１の板厚はｔ２であり、板厚ｔ２は、第１接合部８２の板厚ｔ１より薄く、例えば、ｔ２＝０．５×ｔ１である。   The plate thickness of the first separation flat plate portion 91 is t2, and the plate thickness t2 is thinner than the plate thickness t1 of the first joint portion 82, for example, t2 = 0.5 × t1.

次に、本発明の車体前部構造の作用を説明する。
図７は、本発明の車体前部構造（第１部品取付ブラケット）の衝撃吸収の機構を説明する図である。
車体前部構造１１では、正面衝突したときに、サイドフレーム１４が変形することで衝撃を吸収するとともに、サイドフレーム１４の衝撃吸収の変形に同期して第１部品取付ブラケット２１は変形する。つまり、第１部品取付ブラケット２１はサイドフレーム１４の座屈変形を妨げない。 Next, the operation of the vehicle body front structure of the present invention will be described.
FIG. 7 is a view for explaining a shock absorbing mechanism of the vehicle body front structure (first component mounting bracket) according to the present invention.
In the vehicle body front structure 11, when a frontal collision occurs, the side frame 14 is deformed to absorb the shock, and the first component mounting bracket 21 is deformed in synchronization with the shock absorption deformation of the side frame 14. That is, the first component mounting bracket 21 does not prevent buckling deformation of the side frame 14.

具体的には、衝突によってサイドフレーム１４に圧縮の荷重が矢印ａ７のように加わると、サイドフレーム１４は座屈して潰れつつ荷重を吸収しながら、変形（潰れ）が第１部品取付ブラケット２１を取付けている外辺部４９の部位４９ａまで達すると、第１部品取付ブラケット２１の第１接合部８２間の外辺部４９の部位４９ａでも引き続きほぼ同様に圧縮による変形（潰れ）を続け、衝撃を吸収し続ける。その際、第１乖離平板部９１はサイドフレーム１４の外辺部４９を変形しないよう拘束するが、第１乖離平板部９１の板厚ｔ２を薄くしているので、拘束力つまり、変形を妨げる力は極めて小さく、サイドフレーム１４の第１部品取付ブラケット２１を取付けている部位４９ａはほぼ自由状態に近い状態で潰れる。
このように、車体前部構造１１ではサイドフレーム１４を無駄なく潰すことができる。 Specifically, when a compressive load is applied to the side frame 14 by the collision as shown by an arrow a7, the side frame 14 buckles and collapses while absorbing the load, and the deformation (collapse) causes the first component mounting bracket 21 to be deformed. When reaching the portion 49a of the attached outer side portion 49, the portion 49a of the outer side portion 49 between the first joint portions 82 of the first component mounting bracket 21 continues to be deformed (collapsed) by compression in a similar manner, and the impact Continue to absorb. At this time, the first divergence flat plate portion 91 restrains the outer side portion 49 of the side frame 14 from being deformed. However, since the plate thickness t2 of the first divergence flat plate portion 91 is thinned, the restraining force, that is, deformation is hindered. The force is extremely small, and the portion 49a of the side frame 14 to which the first component mounting bracket 21 is attached is crushed in a state almost close to the free state.
Thus, the side frame 14 can be crushed without waste in the vehicle body front structure 11.

次に、本発明の車体前部構造の第２部品取付ブラケットを説明する。
図８は、図３の８矢視図である。拡大して示している。

第２部品取付ブラケット２２は、具体的には、サイドフレーム１４から平行に距離Ｂ２だけ離して配置している第２乖離平板部１０１が形成され、第２乖離平板部１０１から直交してサイドフレーム１４の下辺部４７まで延びて、下辺部４７に面接触し且つ、第２乖離平板部１０１の外方（矢印ａ６の方向）及び第２乖離平板部１０１の内方（矢印ａ８の方向）に延びている第２接合部８８、第２接合部８９が形成され、第２接合部８８の縁が第２縁開先部１０２、第２接合部８９の角が第２縁開先部１０３をなしていて、第２縁開先部１０２に溶接のビード１０４を施し、第２縁開先部１０３にビード１０５を施すことでサイドフレーム１４に接合されている。さらに、第２乖離平板部１０１の他方に支持傾斜部１０７が形成され、支持傾斜部１０７に連ね第２乖離平板部１０１に達する補強辺部１０８が形成されている。
ビード１０４、１０５がそれぞれ溶接軸８７を有している。 Specifically, the second component mounting bracket 22 is formed with a second divergence flat plate portion 101 arranged parallel to the side frame 14 by a distance B2 and is orthogonal to the second divergence flat plate portion 101 to form a side frame. 14 extends to the lower side portion 47, is in surface contact with the lower side portion 47, and is located outward (in the direction of the arrow a <b> 6) of the second deviation flat plate portion 101 and inward (in the direction of the arrow a <b> 8). The extended second joint 88 and the second joint 89 are formed, the edge of the second joint 88 is the second edge groove 102, and the corner of the second joint 89 is the second edge groove 103. At the same time, a weld bead 104 is applied to the second edge groove portion 102, and a bead 105 is applied to the second edge groove portion 103 so as to be joined to the side frame 14. Further, a support inclined portion 107 is formed on the other side of the second detaching flat plate portion 101, and a reinforcing side portion 108 that reaches the second detaching flat plate portion 101 is formed so as to be connected to the support inclined portion 107.
Each of the beads 104 and 105 has a welding shaft 87.

第２接合部８８は、第２乖離平板部１０１からサイドフレーム１４まで延びる脚部１１１が形成され、脚部１１１に直交させ且つ、下辺部４７に平行に脚当接部１１２が第２接合部８８の板厚ｔ３の約１．６倍の長さＬ１で形成されて、脚当接部１１２が面接触している。
第２接合部８９には、脚部１１４、脚当接部１１５が形成され、下辺部４７に脚当接部１１５が面接触している。 The second joint portion 88 is formed with a leg portion 111 extending from the second separation flat plate portion 101 to the side frame 14, and the leg contact portion 112 is perpendicular to the leg portion 111 and parallel to the lower side portion 47. The leg contact portion 112 is in surface contact with the length L1 of about 1.6 times the plate thickness t3 of 88.
A leg portion 114 and a leg contact portion 115 are formed in the second joint portion 89, and the leg contact portion 115 is in surface contact with the lower side portion 47.

第２接合部８８、８９の板厚はｔ３である。
第２乖離平板部１０１の板厚はｔ４であり、板厚ｔ４は、第２接合部８８、８９の板厚ｔ３より薄く、例えば、ｔ４＝０．５×ｔ３である。 The plate thickness of the second joint portions 88 and 89 is t3.
The plate thickness of the second deviation flat plate portion 101 is t4, and the plate thickness t4 is thinner than the plate thickness t3 of the second joint portions 88 and 89, for example, t4 = 0.5 × t3.

なお、第２部品取付ブラケット２２では、支持傾斜部１０７に設けためねじ部１１７にボルト１１８を所望の軸力（例えば、トルク管理）でねじ込むことで前部品３７の横取付部材４２を締結している。   In the second component mounting bracket 22, the lateral mounting member 42 of the front component 37 is fastened by screwing the bolt 118 into the screw portion 117 with a desired axial force (for example, torque management) to be provided on the support inclined portion 107. Yes.

車体前部構造１１では、第２部品取付ブラケット２２は、第１部品取付ブラケット２１と同様の作用効果を発揮する。つまり、第２部品取付ブラケット２２はサイドフレーム１４の変形を妨げない。
このように、車体前部構造１１ではサイドフレーム１４を無駄なく潰すことができる。 In the vehicle body front structure 11, the second component mounting bracket 22 exhibits the same effects as the first component mounting bracket 21. That is, the second component mounting bracket 22 does not hinder the deformation of the side frame 14.
