Description

緩衝装置支持部材、緩衝装置支持構造体および車両Shock absorber support member, shock absorber support structure, and vehicle
　本発明は、緩衝装置支持部材、緩衝装置支持構造体および車両、詳しくは、緩衝装置の支持に用いられる緩衝装置支持部材、それを備える緩衝装置支持構造体、および、車両に関する。 The present invention relates to a shock absorber support member, a shock absorber support structure, and a vehicle, and more particularly, to a shock absorber support member used for supporting the shock absorber, a shock absorber support structure including the shock absorber support member, and a vehicle.
　自動車などの車両には、車体の前側および／または後側に、緩衝装置が設けられており、自動車が、歩行者や周囲の他の自動車などの対象物と衝突した際には、緩衝装置によって急激な衝撃を緩和するようにしている。そのような緩衝装置は、バンパリインフォースメントなどの車体に取り付けられる。 A vehicle such as an automobile is provided with a shock absorber on the front side and / or the rear side of the vehicle body. When the car collides with an object such as a pedestrian or other surrounding cars, the shock absorber is used. I try to relieve sudden impacts. Such a shock absorber is attached to a vehicle body such as a bumper reinforcement.
　また、拘束層と、それに積層される粘弾性層とを備え、拘束層が、第１壁と、それと間隔を隔てて対向配置される第２壁と、それらの間に架設される筋壁とを一体的に備える補強シートが提案されている（例えば、特許文献１参照。）。 And a constraining layer and a viscoelastic layer laminated thereon, the constraining layer including a first wall, a second wall disposed opposite to the first wall, and a muscle wall constructed therebetween. Has been proposed (see, for example, Patent Document 1).
特開２０１０－９９８６７号公報JP 2010-99867 A
　しかるに、特許文献１で提案される補強シートを、バンパリインフォースメントと緩衝装置との間に配置して、バンパリインフォースメントを支持することが検討されている。そのような補強シートからなる支持部材は、剛性に優れていることから、緩衝装置を確実に支持することができる。 However, it has been studied to support the bumper reinforcement by arranging the reinforcing sheet proposed in Patent Document 1 between the bumper reinforcement and the shock absorber. Since the support member made of such a reinforcing sheet is excellent in rigidity, the shock absorber can be reliably supported.
　しかるに、支持部材には、対象物との衝突方向から大きな衝撃が加えられたときに、緩衝装置で緩衝し切れない衝撃を吸収する必要があり、つまり、所定方向からの衝撃に緩衝作用を奏することも要求されている。しかし、上記した補強シートからなる支持部材は、変形しにくく、上記した衝撃を吸収することができないという不具合がある。 However, when a large impact is applied to the support member from the direction of collision with the object, it is necessary to absorb an impact that cannot be fully buffered by the shock absorber, that is, it has a buffering effect against the impact from a predetermined direction. That is also required. However, the support member made of the above-described reinforcing sheet is difficult to be deformed and has a problem that it cannot absorb the above-described impact.
　本発明の目的は、特定方向に外力が加えられた場合に、確実に屈曲することのできる、緩衝装置支持部材、緩衝装置支持構造体および車両を提供することにある。 An object of the present invention is to provide a shock absorber support member, a shock absorber support structure, and a vehicle that can be reliably bent when an external force is applied in a specific direction.
　本発明の緩衝装置支持部材は、車体と、前記車体に取り付けられる緩衝装置との間に介在され、前記緩衝装置を支持するための緩衝装置支持部材であって、平板状部材と、前記平板状部材に一方向に沿って形成され、外力が加わることによって屈曲する応力集中部とを備えることを特徴としている。 The shock absorber supporting member of the present invention is a shock absorber supporting member that is interposed between a vehicle body and a shock absorber attached to the vehicle body and supports the shock absorber, and includes a flat plate member and the flat plate member. It is characterized by comprising a stress concentration portion that is formed along one direction on the member and bends when an external force is applied.
　この緩衝装置支持部材には、外力が加わることによって屈曲する応力集中部が、平板状部材に形成されている。そのため、外力が緩衝装置から応力集中部に加えられると、平板状部材を屈曲させることができる。 In this shock absorber support member, a stress concentration portion that is bent when an external force is applied is formed on the flat plate member. Therefore, when an external force is applied from the shock absorber to the stress concentration portion, the flat plate member can be bent.
　しかも、応力集中部が平板状部材に、一方向に沿って形成されているので、外力がかかる部位において、平板状部材を、一方向に沿って確実に屈曲させることができる。 In addition, since the stress concentration portion is formed in the flat plate member along one direction, the flat plate member can be reliably bent along the one direction in a portion where an external force is applied.
　換言すれば、外力がかかる部位において、平板状部材は、一方向に対する交差方向に沿って屈曲しにくいので、交差方向に沿う屈曲などの変形を有効に防止することができる。 In other words, in a portion to which an external force is applied, the flat plate member is difficult to bend along the intersecting direction with respect to one direction, so that deformation such as bending along the intersecting direction can be effectively prevented.
　その結果、緩衝装置支持部材は、特定方向にかかる外力を、平板状部材の一方向に沿う屈曲によって、確実に吸収することができるとともに、特定方向以外の方向にかかる外力に起因する変形を有効に防止することができる。 As a result, the shock absorber support member can reliably absorb the external force applied in a specific direction by bending the flat plate member along one direction, and effectively deforms due to the external force applied in a direction other than the specific direction. Can be prevented.
　また、本発明の緩衝装置支持部材では、前記応力集中部は、前記平板状部材の全面にわたって形成されていることが好適である。 In the shock absorber supporting member of the present invention, it is preferable that the stress concentration portion is formed over the entire surface of the flat plate member.
　この緩衝装置支持部材では、応力集中部は、平板状部材の全面にわたって形成されているので、平板状部材をどのような形状に形成しても、外力を応力集中部に作用させることができる。 In this shock absorber support member, since the stress concentration portion is formed over the entire surface of the flat plate member, an external force can be applied to the stress concentration portion regardless of the shape of the flat plate member.
　また、本発明の緩衝装置支持部材では、前記平板状部材には、前記緩衝装置に隣接する隣接部分に弾性部材が設けられていることが好適である。 In the shock absorber supporting member of the present invention, it is preferable that the flat plate member is provided with an elastic member in an adjacent portion adjacent to the shock absorber.
　この緩衝装置支持部材によれば、緩衝装置を、緩衝装置支持部材によって、弾性的に支持することができる。 According to the shock absorber support member, the shock absorber can be elastically supported by the shock absorber support member.
　また、本発明の緩衝装置支持部材では、前記平板状部材には、前記緩衝装置に隣接する隣接部分に、前記緩衝装置に対して滑る滑り部材が設けられていることが好適である。 In the shock absorber supporting member of the present invention, it is preferable that the flat plate member is provided with a sliding member that slides with respect to the shock absorber in an adjacent portion adjacent to the shock absorber.
　この緩衝装置支持部材では、緩衝装置が変形する際には、緩衝装置が、滑り部材によって、緩衝装置支持部材に対して滑ることができる。そのため、緩衝装置の円滑な変形を確保して、緩衝装置にかかる外力を効率的に吸収することができる。 In this shock absorber support member, when the shock absorber is deformed, the shock absorber can slide relative to the shock absorber support member by the sliding member. Therefore, it is possible to ensure smooth deformation of the shock absorber and efficiently absorb the external force applied to the shock absorber.
　また、滑り部材を設けることにより、緩衝装置の摩擦による劣化を防止することができる。 Moreover, by providing the sliding member, it is possible to prevent the shock absorber from being deteriorated due to friction.
　また、本発明の緩衝装置支持部材では、前記平板状部材が、複数設けられていることが好適である。 In the shock absorber supporting member of the present invention, it is preferable that a plurality of the flat plate-like members are provided.
　この緩衝装置支持部材では、前記平板状部材が、複数設けられている。そのため、緩衝装置支持部材は、特定方向にかかる外力を、複数の平板状部材の一方向に沿う屈曲によって、より一層確実に吸収することができるとともに、特定方向以外の方向にかかる外力に起因する変形を複数の平板状部材の交差方向に沿う変形防止によって、より一層有効に防止することができる。 In this shock absorber support member, a plurality of the plate-like members are provided. Therefore, the shock absorber supporting member can absorb the external force applied in the specific direction more reliably by bending along one direction of the plurality of flat plate-like members, and is caused by the external force applied in a direction other than the specific direction. The deformation can be more effectively prevented by preventing the deformation along the intersecting direction of the plurality of flat members.
　また、本発明の緩衝装置支持部材では、前記平板状部材は、第１平板、第１平板と間隔を隔てて対向配置される第２平板、および、第１平板と第２平板との間に架設され、前記一方向に対する交差方向に互いに間隔を隔てて併設される複数の柱部を備え、前記応力集中部は、各前記柱部の間に形成される脆弱部であることが好適である。 Moreover, in the shock absorber supporting member of the present invention, the flat plate member includes a first flat plate, a second flat plate arranged opposite to the first flat plate with a space therebetween, and between the first flat plate and the second flat plate. It is preferable that the apparatus includes a plurality of pillar portions that are installed in a crossing direction with respect to the one direction and spaced apart from each other, and the stress concentration portion is a fragile portion formed between the pillar portions. .
　この緩衝装置支持部材では、平板状部材が、第１平板、第２平板および柱部を備え、柱部の間に脆弱部が形成されている。 In this shock absorber supporting member, the flat plate member includes the first flat plate, the second flat plate, and the column portion, and a fragile portion is formed between the column portions.
　そのため、柱部によって、平板状部材の強度を維持することができる。 Therefore, the strength of the flat plate member can be maintained by the pillar portion.
　一方、柱部が、交差方向に互いに間隔を隔てて併設されている。すなわち、脆弱部が、交差方向に沿って形成される。そのため、交差方向において、平板状部材を屈曲させることができる。 On the other hand, the pillars are provided side by side in the crossing direction at intervals. That is, the weak part is formed along the intersecting direction. Therefore, the flat plate member can be bent in the intersecting direction.
　また、本発明の緩衝装置支持部材では、前記平板状部材における前記交差方向の垂直圧縮強さが、前記平板状部材における前記一方向の垂直圧縮強さの０．１倍以上１倍未満であることが好適である。 In the shock absorber supporting member of the present invention, the vertical compressive strength in the intersecting direction of the flat plate member is 0.1 times or more and less than 1 time of the vertical compressive strength in the one direction of the flat plate member. Is preferred.
　この緩衝装置支持部材では、平板状部材の交差方向における垂直圧縮強さが、平板状部材の一方向における垂直圧縮強さの０．１倍以上１倍未満である。すなわち、平板状部材において、脆弱部が並設される方向における垂直圧縮強さが、一方向における垂直圧縮強さよりも低く設定されている。そのため、脆弱部が併設される方向に沿って外力が加わることによって、容易に、平板状部材を屈曲させることができる。 In this shock absorber support member, the vertical compressive strength in the crossing direction of the flat plate member is 0.1 times or more and less than 1 times the vertical compressive strength in one direction of the flat plate member. That is, in the flat plate member, the vertical compressive strength in the direction in which the fragile portions are juxtaposed is set lower than the vertical compressive strength in one direction. Therefore, the flat member can be easily bent by applying an external force along the direction in which the fragile portion is provided.
　また、本発明の緩衝装置支持構造体は、車体と、前記車体に取り付けられる緩衝装置と、前記車体と前記緩衝装置との間に介在され、前記緩衝装置を支持するための、上記した緩衝装置支持部材とを備えることを特徴としている。 In addition, the shock absorber support structure of the present invention is a shock absorber described above, which is interposed between the vehicle body, the shock absorber attached to the vehicle body, the vehicle body and the shock absorber, and supports the shock absorber. And a support member.
　この緩衝装置支持構造体では、緩衝装置支持部材は、特定方向にかかる外力を、平板状部材の一方向に沿う屈曲によって、確実に吸収することができるとともに、特定方向以外の方向にかかる外力に起因する変形を有効に防止することができる。 In this shock absorber support structure, the shock absorber support member can reliably absorb the external force applied in a specific direction by bending the flat plate member along one direction, and can apply the external force applied in a direction other than the specific direction. The resulting deformation can be effectively prevented.
　そのため、特定方向にかかる外力を、平板状部材の一方向に沿う屈曲によって、確実に吸収することができるとともに、特定方向以外の方向にかかる外力に起因する変形を有効に防止することができる。 Therefore, an external force applied in a specific direction can be reliably absorbed by bending along one direction of the flat plate member, and deformation due to an external force applied in a direction other than the specific direction can be effectively prevented.
　また、本発明の車両は、車体と、前記車体に取り付けられる緩衝装置と、前記車体と前記緩衝装置との間に介在され、前記緩衝装置を支持するための、上記した緩衝装置支持部材とを備えることを特徴としている。 Further, the vehicle of the present invention includes a vehicle body, a shock absorber attached to the vehicle body, and the shock absorber support member interposed between the vehicle body and the shock absorber and supporting the shock absorber.

Preferably, an olefin resin is used, and more preferably, polypropylene is used.
　第１平板１３および第２平板１４は、例えば、上記した熱可塑性樹脂を押出成形などによって、平板状に形成することにより得られる。 The first flat plate 13 and the second flat plate 14 are obtained, for example, by forming the above-described thermoplastic resin into a flat plate shape by extrusion molding or the like.

Moreover, when the vertical compressive strength S1 in the front-back direction of the support sheet 10 is higher than the above range, it may be difficult to bend the support sheet 10 (flat plate member 8) along the intended direction.
　なお、垂直圧縮強さ（エンドクラッシュ）は、上記した方向において、ＪＩＳ　Ｚ　０４０３－２に準じて求められる。 The vertical compressive strength (end crush) is obtained according to JIS Z 0403-2 in the above-mentioned direction.

　次に、図１に示されるバンパ支持部材１を備える車両としての自動車（緩衝装置支持構造体）３０について、図７～図９を参照して説明する。 Next, an automobile (buffer support structure) 30 as a vehicle including the bumper support member 1 shown in FIG. 1 will be described with reference to FIGS.
　図７は、自動車の一部拡大斜視図、図８は、図７の自動車のバンパがバンパ支持部材によって支持された緩衝装置支持構造体の側断面図、図９は、図８に示す緩衝装置支持構造体の平面図を示す。 7 is a partially enlarged perspective view of the automobile, FIG. 8 is a side sectional view of a shock absorber support structure in which the bumper of the automobile of FIG. 7 is supported by a bumper support member, and FIG. 9 is a shock absorber shown in FIG. The top view of a support structure is shown.
　自動車３０は、図７に示すように、ラジエータ３５（図９参照）およびエンジン（図示せず）などを収容するラジエータサポート３１と、ラジエータサポート３１の前端部の下側に設けられるバンパ補強材２と、バンパ補強材２の前方に間隔を隔てて設けられるバンパ３（図８および図９参照）とを備えている。 As shown in FIG. 7, the automobile 30 includes a radiator support 31 that houses a radiator 35 (see FIG. 9), an engine (not shown), and the like, and a bumper reinforcing member 2 that is provided below the front end of the radiator support 31. And a bumper 3 (see FIG. 8 and FIG. 9) provided at a distance in front of the bumper reinforcing member 2.
　ラジエータサポート３１は、自動車３０の前側に設けられ、平面視略矩形枠状に形成されている。 The radiator support 31 is provided on the front side of the automobile 30 and is formed in a substantially rectangular frame shape in plan view.
　バンパ補強材２は、前側バンパ補強材であって、ラジエータサポート３１の前壁３２の下部に設けられている。また、バンパ補強材２は、ラジエータサポート３１の前壁３２の下部の左右方向両端を架設するように、左右方向に延びるように形成されている。 The bumper reinforcing material 2 is a front bumper reinforcing material, and is provided at a lower portion of the front wall 32 of the radiator support 31. Further, the bumper reinforcing member 2 is formed to extend in the left-right direction so as to extend both left and right ends of the lower portion of the front wall 32 of the radiator support 31.
　また、バンパ補強材２は、図８に示すように、側断面略矩形枠状に形成されている。さらに、バンパ補強材２の上壁の左右方向途中（中央）には、厚み方向（上下方向）を貫通する固定孔３３が形成されている。固定孔３３は、図７に示すように、平面視略円形状をなし、左右方向に間隔を隔てて複数（２つ）形成されている。 Further, as shown in FIG. 8, the bumper reinforcing material 2 is formed in a substantially rectangular frame shape in a side section. Furthermore, a fixing hole 33 penetrating in the thickness direction (vertical direction) is formed in the middle (center) of the upper wall of the bumper reinforcing material 2 in the left-right direction. As shown in FIG. 7, the fixing hole 33 has a substantially circular shape in plan view, and a plurality (two) of the fixing holes 33 are formed at intervals in the left-right direction.
　バンパ３は、図８および図９に示すように、バンパ補強材２の前方斜め上側に、間隔を隔てて設けられ、左右方向に延びる板状をなし、左右方向中央部が前側に向かって湾曲する平断面略弓形状に形成されている。なお、バンパ３は、その左右方向両端部において、連結部（図示せず）を介して、バンパ補強材２の左右方向両端部に連結されている。 As shown in FIGS. 8 and 9, the bumper 3 is provided on the diagonally upper front side of the bumper reinforcing member 2 with a space therebetween, has a plate shape extending in the left-right direction, and a central portion in the left-right direction is curved toward the front side. The flat cross section is formed in a substantially bow shape. The bumper 3 is connected to both left and right ends of the bumper reinforcing member 2 via connecting portions (not shown) at both left and right ends.
　そして、バンパ支持部材１は、バンパ補強材２と、バンパ３との間に配置されている。 The bumper support member 1 is disposed between the bumper reinforcement 2 and the bumper 3.
　バンパ支持部材１をバンパ補強材２とバンパ３との間に配置するには、例えば、図７の自動車３０において、まず、図８に示すように、バンパ補強材２の固定孔３３に、クリップ７の固定部２３を挿入する。 In order to arrange the bumper support member 1 between the bumper reinforcement member 2 and the bumper 3, for example, in the automobile 30 of FIG. 7, first, as shown in FIG. 7 fixing portion 23 is inserted.
　これにより、平板状部材８の後部１１の下端縁が、バンパ補強材２の上面に当接する。なお、これと同時に、平板状部材８の前部１２の後端縁が、バンパ補強材２の前面に当接する。 Thereby, the lower end edge of the rear portion 11 of the flat plate member 8 comes into contact with the upper surface of the bumper reinforcing material 2. At the same time, the rear end edge of the front portion 12 of the flat plate member 8 comes into contact with the front surface of the bumper reinforcing member 2.
　次いで、バンパ３を、その裏面（後面）が、平板状部材８の前部１２の前縁部２１と前後方向に隣接するように、バンパ補強材２に連結部（図示せず）を介して連結させる。 Next, the bumper 3 is connected to the bumper reinforcing member 2 via a connecting portion (not shown) so that the back surface (rear surface) of the bumper 3 is adjacent to the front edge portion 21 of the front portion 12 of the flat plate member 8 in the front-rear direction. Connect.
　なお、バンパ３のバンパ補強材２への連結によって、バンパ３の裏面は、弾性部材５の表面に設けられる滑り部材６と摺動自在に接触し、それにより、バンパ３は、バンパ支持部材１によって弾性的に支持される。 By connecting the bumper 3 to the bumper reinforcing member 2, the back surface of the bumper 3 is slidably in contact with the sliding member 6 provided on the surface of the elastic member 5, so that the bumper 3 is supported by the bumper support member 1. Is elastically supported by.
　この自動車３０では、図９の矢印で示すように、第１平板状部材８Ａと第２平板状部材８Ｂとによって、バンパ３の前方から、パンパ３とラジエータ３５との間の空間を通過して、ラジエータ３５に入る空気の流れを整えることができる。つまり、第１平板状部材８Ａと第２平板状部材８Ｂとが、空気の整流板の作用を発現することができる。 In this automobile 30, as shown by the arrows in FIG. 9, the first flat plate member 8A and the second flat plate member 8B pass through the space between the bumper 3 and the radiator 35 from the front of the bumper 3. The flow of air entering the radiator 35 can be adjusted. That is, the first flat plate member 8 </ b> A and the second flat plate member 8 </ b> B can exhibit the action of the air rectifying plate.
　そのため、ラジエータ３５の空気特性（空力特性）を向上させることができる。 Therefore, the air characteristics (aerodynamic characteristics) of the radiator 35 can be improved.
　図１０は、図９の緩衝装置支持構造体における平板状部材の屈曲を説明する平面図を示す。 FIG. 10 is a plan view for explaining the bending of the flat plate member in the shock absorber supporting structure of FIG.
　次に、バンパ３に外力としての衝撃力Ｉが加わった場合におけるバンパ支持部材１の作用について、図１０を参照して説明する。 Next, the operation of the bumper support member 1 when an impact force I as an external force is applied to the bumper 3 will be described with reference to FIG.
　衝撃力Ｉが加わる方向（図１０において矢印で示す方向）は、例えば、自動車３０が対象物と正面衝突することにより、バンパ３の前面に衝撃力Ｉが前側から後側に向かう方向として想定される。 The direction in which the impact force I is applied (the direction indicated by the arrow in FIG. 10) is assumed as the direction in which the impact force I is directed from the front side to the rear side on the front surface of the bumper 3, for example, when the automobile 30 collides with the object. The
　バンパ３は、図１０に示すように、衝撃力Ｉが前側から後側に加わることにより、変形する。このとき、衝撃力Ｉが、バンパ３によって吸収しきれない場合には、バンパ３は、平板状部材８を後側に向かって強く押圧する。 As shown in FIG. 10, the bumper 3 is deformed when an impact force I is applied from the front side to the rear side. At this time, when the impact force I cannot be absorbed by the bumper 3, the bumper 3 strongly presses the flat plate member 8 toward the rear side.
　すると、平板状部材８にかかる応力は、衝撃力Ｉの加わり方（衝撃力の大きさ、方向、加わる部位など）に対応して、平板状部材８のいずれかの部位に集中する。 Then, the stress applied to the flat plate member 8 is concentrated on any portion of the flat plate member 8 in accordance with the way of applying the impact force I (the magnitude, direction, applied portion, etc. of the impact force).
　例えば、各平板状部材８には、脆弱部２９（図４および図８）が形成されているので、特に応力が集中する脆弱部２９において、第１平板１３および第２平板１４（図２）のいずれかが左右方向に屈曲することにより、平板状部材８が屈曲する。 For example, each flat plate member 8 is formed with a fragile portion 29 (FIGS. 4 and 8), so that the first flat plate 13 and the second flat plate 14 (FIG. 2) particularly in the fragile portion 29 where stress is concentrated. Is bent in the left-right direction, whereby the flat plate member 8 is bent.
　例えば、平板状部材８は、後部１１および前部１２との境界３４（図８参照）の近傍における脆弱部２９において、上下方向に沿って屈曲する。 For example, the flat plate member 8 bends in the vertical direction at the fragile portion 29 in the vicinity of the boundary 34 (see FIG. 8) with the rear portion 11 and the front portion 12.
　次に、バンパ３に外力としての荷重Ｇが加わった場合におけるバンパ支持部材１の作用について、図８を参照して説明する。 Next, the operation of the bumper support member 1 when a load G as an external force is applied to the bumper 3 will be described with reference to FIG.
　荷重Ｇが加わる方向（図８において矢印で示す方向）は、例えば、ラジエータサポート３１に収容されるラジエータやエンジンなどの保守および点検する作業者が、足をバンパ３に掛けて、荷重Ｇが上側から下側に向かう方向、あるいは、バンパ３の自重による荷重Ｇが鉛直方向下側に向かう方向が想定される。 The direction in which the load G is applied (the direction indicated by the arrow in FIG. 8) is such that, for example, an operator who maintains and inspects the radiator and engine accommodated in the radiator support 31 hangs his feet on the bumper 3 and the load G is on the upper side. A direction in which the load G due to the weight of the bumper 3 is directed downward is assumed.
　また、荷重Ｇは、上記したように作業者の体重あるいはバンパ３の自重に基づくため、上記した衝撃力Ｉに比べて小さい。 Further, since the load G is based on the weight of the worker or the weight of the bumper 3 as described above, it is smaller than the impact force I described above.
　バンパ３０は、図８に示すように、荷重Ｇが上側から下側に向かって加わることによっても、変形を実質的に生じず（あるいは、わずかに変形し）、次いで、バンパ３が、平板状部材８を下側に向かって比較的弱く押圧する。つまり、平板状部材８に、荷重Ｇに基づく応力が上下方向にかかる。 As shown in FIG. 8, the bumper 30 is not substantially deformed (or slightly deformed) even when a load G is applied from the upper side to the lower side. Next, the bumper 3 has a flat plate shape. The member 8 is pressed relatively weakly downward. That is, a stress based on the load G is applied to the flat plate member 8 in the vertical direction.
　すると、板状部材４にかかる応力は、荷重Ｇによっても、脆弱部２９（図２参照）が、上下方向に沿って形成されていることから、平板状部材８において応力集中が発生せず、平板状部材の上下方向全体にかかる。そのため、平板状部材８は、上記した屈曲などの変形を生じない。 Then, the stress applied to the plate-like member 4 is not caused by stress concentration in the plate-like member 8 because the fragile portion 29 (see FIG. 2) is formed along the vertical direction even by the load G. It covers the entire vertical direction of the flat member. Therefore, the flat plate member 8 does not undergo deformation such as the above-described bending.
　そして、このバンパ支持部材１には、外力（衝撃力Ｉ）が加わることによって屈曲する応力集中部（脆弱部）２１が、平板状部材８に形成されている。そのため、衝撃力Ｉがバンパ３から応力集中部に加えられると、平板状部材８を屈曲させることができる。 The bumper support member 1 is formed with a stress concentration portion (fragile portion) 21 that is bent when an external force (impact force I) is applied. Therefore, when the impact force I is applied from the bumper 3 to the stress concentration portion, the flat plate member 8 can be bent.
　しかも、応力集中部が平板状部材８に、上下方向に沿って形成されているので、衝撃力Ｉがかかる部位、例えば、上記した境界３４において、平板状部材８を、上下方向に沿って確実に屈曲させることができる。 In addition, since the stress concentration portion is formed on the flat member 8 along the vertical direction, the flat member 8 is securely moved along the vertical direction at the portion where the impact force I is applied, for example, at the boundary 34 described above. Can be bent.
　換言すれば、平板状部材８は、上下方向（脆弱部形成方向Ｆ）に対して交差する前後方向に沿って屈曲しにくいので、前後方向に沿う屈曲などの変形を有効に防止することができる。 In other words, the flat plate member 8 is difficult to bend along the front-rear direction intersecting with the up-down direction (fragile part forming direction F), and thus deformation such as bending along the front-rear direction can be effectively prevented. .
　その結果、バンパ支持部材１は、前後方向にかかる衝撃力Ｉを、平板状部材８の上下方向に沿う屈曲によって、確実に吸収することができるとともに、上下方向にかかる荷重Ｇに起因する変形を有効に防止することができる。 As a result, the bumper support member 1 can reliably absorb the impact force I applied in the front-rear direction by bending the plate-shaped member 8 along the vertical direction, and can also deform due to the load G applied in the vertical direction. It can be effectively prevented.
　また、このバンパ支持部材１では、脆弱部２９は、平板状部材８の全面にわたって形成されているので、平板状部材８をどのような形状に形成しても、衝撃力Ｉを脆弱部２９に作用させることができる。 In this bumper support member 1, the fragile portion 29 is formed over the entire surface of the flat plate member 8, so that the impact force I is applied to the fragile portion 29 regardless of the shape of the flat plate member 8. Can act.
　また、平板状部材８は、突出部１６によって、強度を維持することができる。 Further, the flat plate member 8 can maintain the strength by the protruding portion 16.
　また、突出部１６の列（突出部列１８）が、前後方向に互いに間隔を隔てて併設されている。すなわち、脆弱部２９が、前後方向に沿って形成される。そのため、前後方向（脆弱部形成方向Ｆ）において、平板状部材８を確実に屈曲させることができる。 Further, the row of the protruding portions 16 (the protruding portion row 18) is provided side by side with a space in the front-rear direction. That is, the fragile portion 29 is formed along the front-rear direction. Therefore, the flat plate member 8 can be reliably bent in the front-rear direction (fragile portion forming direction F).
　また、平板状部材８において、脆弱部２９が並設される方向（前後方向）における垂直圧縮強さＳ１が、上下方向における垂直圧縮強さＳ２よりも低い特定範囲に設定されている。そのため、前後方向（脆弱部形成方向Ｆ）に沿って衝撃力Ｉが加わることによって、容易に、平板状部材８をそれぞれ屈曲させることができる。 In the flat plate member 8, the vertical compressive strength S1 in the direction (front-rear direction) in which the fragile portions 29 are arranged side by side is set to a specific range lower than the vertical compressive strength S2 in the vertical direction. Therefore, when the impact force I is applied along the front-rear direction (fragile portion forming direction F), the flat plate members 8 can be easily bent.
　なお、図８の実施形態では、弾性部材５を、平板状部材８において、バンパ３に隣接する前縁部２１に設けているが、例えば、図示しないが、弾性部材５を設けることなく、平板状部材８の前縁部２１を、バンパ３に隣接させることもできる。 In the embodiment of FIG. 8, the elastic member 5 is provided on the front edge portion 21 adjacent to the bumper 3 in the flat plate member 8. For example, although not shown, the elastic member 5 is not provided with the flat plate. The front edge 21 of the shaped member 8 can also be adjacent to the bumper 3.
　好ましくは、弾性部材５を、平板状部材８の前縁部２１に設ける。これにより、バンパ３を、バンパ支持部材１によって、弾性的に支持することができる。 Preferably, the elastic member 5 is provided on the front edge 21 of the flat plate member 8. Thereby, the bumper 3 can be elastically supported by the bumper support member 1.
　また、図８の実施形態では、滑り部材６を平板状部材８の前縁部２１に設けているが、例えば、図示しないが、滑り部材６を設けることなく、平板状部材８の前縁部２１を、バンパ３に隣接させることもできる。 In the embodiment of FIG. 8, the sliding member 6 is provided on the front edge portion 21 of the flat plate member 8. For example, although not shown, the front edge portion of the flat plate member 8 is provided without providing the sliding member 6. 21 can be adjacent to the bumper 3.
　好ましくは、滑り部材６を平板状部材８の前縁部２１に設ける。これにより、バンパ３が変形する際には、バンパ３が、滑り部材６によって、バンパ支持部材１に対して、例えば、左右方向にスライドすることができる。そのため、バンパ３の円滑な変形を確保して、バンパ３にかかる衝撃力Ｉを効率的に吸収することができる。 Preferably, the sliding member 6 is provided on the front edge 21 of the flat plate member 8. Thereby, when the bumper 3 is deformed, the bumper 3 can be slid in the left-right direction with respect to the bumper support member 1 by the sliding member 6. Therefore, smooth deformation of the bumper 3 can be ensured and the impact force I applied to the bumper 3 can be efficiently absorbed.
　また、滑り部材６を設けることにより、自動車３０の振動に起因して、平板状部材８の前縁部２１とバンパ３とが摩擦することを低減できるので、上記した摩擦に基づく平板状部材８の前縁部２１の劣化を防止することができる。 Further, since the sliding member 6 is provided, it is possible to reduce the friction between the front edge portion 21 of the flat plate member 8 and the bumper 3 due to the vibration of the automobile 30, so the flat plate member 8 based on the friction described above. Deterioration of the front edge portion 21 can be prevented.
　また、図１の実施形態では、平板状部材８を、２つ（第１平板状部材８Ａおよび第２平板状部材８Ｂ）設けているが、例えば、図示しないが、１つ（第１平板状部材８Ａおよび第２平板状部材８Ｂのいずれか一方のみ）、あるいは、３つ以上設けることができる。 In the embodiment of FIG. 1, two flat members 8 (first flat member 8A and second flat member 8B) are provided. For example, one (first flat member) is not shown. Only one of the member 8A and the second flat plate member 8B), or three or more members can be provided.
　好ましくは、図１の実施形態のように、平板状部材を複数設ける。これにより、例えばバンパ支持部材１は、前後方向にかかる衝撃力Ｉを、２つの平板状部材８の屈曲によって、より一層確実に吸収することができるとともに、前後方向にかかる荷重Ｇに起因する変形をより一層有効に防止することができる。 Preferably, a plurality of flat members are provided as in the embodiment of FIG. Thereby, for example, the bumper support member 1 can absorb the impact force I applied in the front-rear direction more reliably by the bending of the two flat plate-shaped members 8 and can be deformed due to the load G applied in the front-rear direction. Can be more effectively prevented.
　また、図１の実施形態では、２つの平板状部材８を板状部材９によって連結しているが、板状部材９を形成することなく、それらを独立して設けることもできる。 In the embodiment of FIG. 1, the two flat members 8 are connected by the plate members 9, but they can be provided independently without forming the plate members 9.
　好ましくは、２つの平板状部材８を板状部材９によって連結する。これにより、１枚の１枚の支持シート１０を折曲加工することによって、板状部材９によって連結される２つの平板状部材８を容易に形成することができる。 Preferably, two flat members 8 are connected by a plate member 9. Thereby, the two flat members 8 connected by the plate-like member 9 can be easily formed by bending one support sheet 10.
　さらに、板状部材９の左右方向長さによって、２つの平板状部材８間の間隔を確実に設定することができる。 Furthermore, the distance between the two plate-like members 8 can be reliably set by the length of the plate-like member 9 in the left-right direction.
　また、図１の実施形態では、第１平板状部材８Ａと第２平板状部材８Ｂとを、左右方向に投影した時に、外形形状が略同一となるように形成しているが、第１平板状部材８Ａと第２平板状部材８Ｂとの形状は上記に限定されない。例えば、図示しないが、第１平板状部材８Ａと第２平板状部材８Ｂとは、それらが配置されるバンパ支持部材１およびバンパ３の形状に対応して、左右方向に投影した時に、互いに異なる形状に形成することもできる。 In the embodiment of FIG. 1, the first flat plate member 8A and the second flat plate member 8B are formed so that the outer shapes are substantially the same when projected in the left-right direction. The shape of the member 8A and the second flat plate member 8B is not limited to the above. For example, although not shown, the first flat plate member 8A and the second flat plate member 8B are different from each other when projected in the left-right direction corresponding to the shapes of the bumper support member 1 and the bumper 3 on which they are arranged. It can also be formed into a shape.
　また、図１および図３の実施形態では、支持シート１０を熱プレスによって、境界３４（１点破線）に沿って折曲加工することによって、板状部材４を得ているが、例えば、図示しないが、境界３４（１点破線）に沿って、薄肉部を形成して、支持シート１０を平板状に形成して、用意することもできる。 In the embodiment of FIGS. 1 and 3, the plate-like member 4 is obtained by bending the support sheet 10 along the boundary 34 (one-dot broken line) by hot pressing. However, it is also possible to prepare by forming a thin portion along the boundary 34 (one-dot broken line) and forming the support sheet 10 in a flat plate shape.
　薄肉部は、その周囲の支持シート１０に比べて、厚みが薄い部分として形成され、具体的には、第１平板１３（図５参照）と第２平板１４（図５参照）とが、上下方向中央に（厚み方向途中）に向かって圧縮されるように形成されている。 The thin-walled portion is formed as a portion that is thinner than the surrounding support sheet 10. Specifically, the first flat plate 13 (see FIG. 5) and the second flat plate 14 (see FIG. 5) are vertically moved. It is formed so as to be compressed toward the center in the direction (in the middle of the thickness direction).
　これにより、薄肉部は、その周囲に比べて強度が低下しているので、可撓性を有し、これによって、薄肉部は、境界３４に沿って、折曲可能に形成されている。 Thereby, since the strength of the thin wall portion is lower than that of the periphery thereof, the thin wall portion has flexibility. Thus, the thin wall portion is formed to be bendable along the boundary 34.
　そのような薄肉部は、平板状の支持シート１０を、上下方向両側からプレスすることによって、形成される。 Such a thin portion is formed by pressing the flat support sheet 10 from both sides in the vertical direction.
　そして、薄肉部が形成されるように用意された支持シート１０を、バンパ補強材２に配置する際、具体的には、クリップ７を係止穴２６に係止させる際に、支持シート１０の薄肉部を境界３４に沿って折り曲げる。この折曲によって、バンパ支持部材１において、平面視略コ字状の板状部材４が形成される。 And when arrange | positioning the support sheet 10 prepared so that a thin part may be formed in the bumper reinforcement 2, specifically, when making the clip 7 latch to the latching hole 26, the support sheet 10 The thin portion is bent along the boundary 34. By this bending, a plate-like member 4 having a substantially U-shape in plan view is formed in the bumper support member 1.
　図１１は、本発明の緩衝装置支持部材の他の実施形態としてのバンパ支持部材の平板状部材を形成するための支持シート（前後方向に隣接する各突出部列１８が重複する態様）の部分拡大平面図を示す。 FIG. 11 shows a portion of a support sheet (a mode in which the protrusion rows 18 adjacent in the front-rear direction overlap) for forming a flat plate member of a bumper support member as another embodiment of the shock absorber support member of the present invention. An enlarged plan view is shown.
　また、図４の実施形態では、前後方向に隣接する各突出部列１８を、前後方向に間隔を隔てて、つまり、左右方向に投影したときに、重複しないように配置しているが、例えば、図１１に示すように、部分的に重複するように配置することもできる。 Further, in the embodiment of FIG. 4, the protrusion rows 18 adjacent in the front-rear direction are arranged so as not to overlap when projected in the front-rear direction at intervals, that is, in the left-right direction. As shown in FIG. 11, it can also arrange | position so that it may overlap partially.
　図１１において、一の突出部列１８ａにおける突出部１６の後端部は、他の突出部列１８ｂにおける突出部１６の前端部と、左右方向に投影したときに、重複している。 In FIG. 11, the rear end of the protrusion 16 in one protrusion row 18a overlaps with the front end of the protrusion 16 in another protrusion row 18b when projected in the left-right direction.
　重複部分の幅Ｗは、例えば、１ｍｍ以下である。 The width W of the overlapping part is, for example, 1 mm or less.
　また、一の突出部列１８ａと、他の突出部列１８ｂとは、前後方向に対して左右方向に傾斜する方向に傾斜する傾斜方向において、間隔を隔てて配置されている。 Further, the one protruding portion row 18a and the other protruding portion row 18b are arranged at an interval in an inclined direction inclined in a direction inclined in the left-right direction with respect to the front-rear direction.
　これによって、脆弱部１１は、各突出部列１８の間に沿う波状に形成されている。 Thus, the fragile portion 11 is formed in a wave shape along each protruding portion row 18.
　また、図７～図９の実施形態では、本発明の車体および緩衝装置を、それぞれ、前側バンパ補強材およびフロントバンパとして、説明しているが、例えば、図示しないが、後側バンパ補強材およびリアバンパなどとして用いることもできる。 7 to 9, the vehicle body and the shock absorber according to the present invention are described as a front bumper reinforcing material and a front bumper, respectively. For example, although not shown, the rear bumper reinforcing material and It can also be used as a rear bumper.
