Description
【考案の詳細な説明】 産業上の利用分野 この考案は、車体前後部のメンバ構造に関するもので
ある。DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention relates to a member structure in the front and rear portions of a vehicle body.
従来の技術 車体後部のリヤサイドメンバには第６図に示すよう
に、後面衝突時にリヤサイドメンバ１の損傷性（後端部
のみを積極的に潰すこと）を向上させて修理費を低減さ
せるためのビード２が形成されたものがある（特開昭58
−116268号公報参照）。2. Description of the Related Art As shown in FIG. 6, the rear side member at the rear of the vehicle body is for improving the damage property of the rear side member 1 (actively crushing only the rear end portion) at the time of a rear surface collision to reduce the repair cost. Some beads 2 are formed (Japanese Unexamined Patent Publication No. 58-58158).
-116268 gazette).
この構造によれば、後面衝突時にこのビード２の部分
で座屈するようにして前方側へ変形が波及するのを防止
している。According to this structure, at the time of a rear-end collision, the portion of the bead 2 is buckled to prevent the deformation from spreading to the front side.
一方、第７図に示すようにリヤサイドメンバ１にはけ
ん引用フック３が取付けられたものがあり、けん引用フ
ック３の取付ブラケット４には、リヤサイドメンバ１の
長手方向に沿って取付けられたレインフォース５の端末
が接合されている。On the other hand, as shown in FIG. 7, there is a rear side member 1 to which a towing hook 3 is attached, and a rain bracket attached to the attachment bracket 4 of the towing hook 3 along the longitudinal direction of the rear side member 1. The terminals of force 5 are joined.
考案が解決しようとする課題 しかしながら、上記従来の構造にあっては、ビード２
を設けることで損傷性を向上させることと、けん引用フ
ック３を取付けるために強度の向上を図ることとが相反
する課題とするため、両者の構造をともに採用すること
ができないという問題がある。However, in the above-mentioned conventional structure, the bead 2 is used.
Since the provision of the above is a contradictory issue of improving the damageability and improving the strength for attaching the towing hook 3, there is a problem that both structures cannot be adopted together.
即ち、ビード２を設けるとけん引用フック３の支持強
度が確保できず、けん引用フック３の支持強度を確保す
ると損傷性が低下してしまうのである。That is, if the bead 2 is provided, the supporting strength of the towing hook 3 cannot be ensured, and if the supporting strength of the towing hook 3 is secured, the damage is reduced.
そこで、この考案はビードとけん引用フックを併設さ
せても損傷性及びけん引用フックの支持強度を確保する
ことができる車体前後部のメンバ構造を提供するもので
ある。Therefore, the present invention provides a member structure in the front and rear portions of the vehicle body that can secure the damage and the supporting strength of the towing hook even if the bead and the towing hook are provided side by side.
課題を解決するための手段 車体前後方向に配設されたメンバの端部付近に脆弱部
が形成され、メンバには脆弱部を前後方向にまたいで補
強部材が取付けられ、補強部材は脆弱部に対応する位置
の幅が狭く形成され、補強部材の端末がメンバに取付け
られたけん引用フックの取付部材に接合されている。Means for Solving the Problems A fragile portion is formed in the vicinity of an end portion of a member arranged in the vehicle front-rear direction, and a reinforcing member is attached to the member across the fragile portion in the front-rear direction. The width of the corresponding position is narrowed, and the end of the reinforcing member is joined to the attachment member of the towing hook attached to the member.
作用 例えば、車両後面衝突時にメンバの端部に荷重が入力
されるとけん引用フックの補強部材は脆弱部に対応する
位置の幅が狭く形成されているためメンバの脆弱部と同
様に座屈してエネルギ吸収を行う。Action For example, if a load is applied to the end of a member during a vehicle rear collision, the reinforcing member of the towing hook will be buckled like the fragile part of the member because the width at the position corresponding to the fragile part is narrow. It absorbs energy.
一方、けん引の際にけん引用フックに引張荷重が作用
すると補強部材がこの引張荷重を受け、脆弱部に引張荷
重が作用するのを防止する。On the other hand, when a tensile load acts on the towing hook during towing, the reinforcing member receives this tensile load, and prevents the tensile load from acting on the fragile portion.
実施例 以下、この考案の一実施例を図面と共に説明する。Embodiment An embodiment of the present invention will be described below with reference to the drawings.
第１〜５図において、６はメンバとしてのハット型断
面形状のリヤサイドメンバを示し、このリヤサイドメン
バ６は車体後部のフロアパネルの両側下面に車体前後方
向に取付けられるものである。1 to 5, reference numeral 6 denotes a rear side member having a hat-shaped cross section as a member. The rear side member 6 is attached to the lower surface of both sides of a floor panel at the rear of the vehicle body in the vehicle front-rear direction.
リヤサイドメンバ６の底壁6aにはこれを横切り脆弱部
としての断面三角形状のビード７が形成されている。On the bottom wall 6a of the rear side member 6, a bead 7 having a triangular cross section is formed as a fragile portion across the bottom wall 6a.
一方、リヤサイドメンバ６の端部には、リヤサイドメ
ンバの底壁6a及び側壁6bに渡る内側面に断面コの字状の
取付部材８が取付けられこの取付部材８上に、上面視Ｕ
字状のけん引用フック９が取付けられている。On the other hand, at the end portion of the rear side member 6, a mounting member 8 having a U-shaped cross section is mounted on the inner side surface extending to the bottom wall 6a and the side wall 6b of the rear side member.
A letter-shaped towing hook 9 is attached.
そして、上記ビード７を前後方向にまたいで、補強部
材10が一端側をリヤサイドメンバ６の底壁6aに他端側は
取付部材８に接合されて取付けられている。The reinforcing member 10 is attached to the bottom wall 6a of the rear side member 6 by joining the bead 7 in the front-rear direction with one end side being joined to the mounting member 8 at the other end side.
補強部材10は第３図に示すようにリヤサイドメンバ６
の突部（図示せず）に整合するロケート孔10aを有する
と共に取付部材８に取付けられる端部には両側に立壁10
bを備えたもので、リヤサイドメンバ６のビード７を横
切る部位には幅狭部10cが形成されている。The reinforcing member 10 is a rear side member 6 as shown in FIG.
Has a locating hole 10a aligned with a protrusion (not shown), and the end portion attached to the attachment member 8 has standing walls 10 on both sides.
The rear side member 6 is formed with a narrow portion 10c at a portion crossing the bead 7.
そして、この補強部材10は、ビード７を逃げるように
やや幅狭部10cで上方に湾曲しているが、略直線状に形
成されている。Then, the reinforcing member 10 is curved upward at the narrow portion 10c so as to escape the bead 7, but is formed in a substantially linear shape.
尚、上記幅狭部10cの寸法は後面衝突時にビード７の
座屈と同時に座屈できる程度に設定されると共にけん引
用フック９により引張荷重が作用した場合にビード７に
負荷をかけないで上記引張荷重に対応するように設定さ
れている。The size of the narrow portion 10c is set so that the bead 7 can buckle at the same time as the buckling of the bead 7 at the time of a rear surface collision, and the bead 7 is not loaded when a tensile load is applied by the towing hook 9. It is set to correspond to the tensile load.
上記実施例構造によれば、リヤサイドメンバ６にビー
ド７が設けられていることにより、車両後面衝突時にお
いてこのビード７の部位での変形（特に座屈）が促進さ
れてエネルギ吸収がなされ、他の部位（前方）に変形が
波及するのが防止される。According to the structure of the above-described embodiment, since the bead 7 is provided on the rear side member 6, the deformation (particularly buckling) of the bead 7 at the time of a rear collision of the vehicle is promoted to absorb the energy. The deformation is prevented from spreading to the part (front) of.
したがって、損傷性に優れ修理コストを低減すること
ができる。Therefore, the damage is excellent and the repair cost can be reduced.
また、このとき補強部材10はその幅狭部10cの部分で
上方に折曲して座屈しビード７の座屈変形に悪影響を及
ぼさない。At this time, the reinforcing member 10 is bent upward at the narrow portion 10c and buckles, so that the buckling deformation of the bead 7 is not adversely affected.
一方、けん引用フック９にけん引のために引張荷重が
作用した場合には、この引張荷重は取付部材８から補強
部材10に作用してこの補強部材10で保持されるため、ビ
ード７には荷重がほとんど作用せず、したがってビード
７は変形してもわずかなものとなる。On the other hand, when a tensile load is applied to the towing hook 9 for towing, this tensile load acts on the reinforcing member 10 from the mounting member 8 and is retained by the reinforcing member 10, so that the bead 7 is loaded with the load. Hardly acts, and therefore the bead 7 is slightly deformed.
尚、この考案は上記実施例に限られるものではなく、
メンバはリヤサイドメンバに限らずフロントサイドメン
バであっても良い。The invention is not limited to the above embodiment,
The member is not limited to the rear side member and may be the front side member.
考案の効果 以上説明してきたようにこの考案によれば、車両衝突

車室中側へ変形が波及するのを防止できるという効果と
ともにけん引時においては、補強部材により十分な引張
強度を確保でき脆弱部に依り、必要な時には損傷を促進
させ、補強部材に依り必要な時に強度を確保するという
相反する課題が解決できるという効果がある。Effect of the Invention As described above, according to the present invention, it is possible to promote the deformation in the vicinity of the fragile portion at the time of a vehicle collision and prevent the deformation from spreading to the inside of the passenger compartment of the member. The effect of being able to secure sufficient tensile strength by the reinforcing member, promoting damage when necessary depending on the fragile portion, and ensuring strength when necessary due to the reinforcing member can be solved.
