Bumper fitting part structure

[Detailed Description of the Invention]

Field of the Invention The present invention relates to the bumper fitting part structure of vehicles. PRIOR ART Generally, the bumper fitting part of vehicles has structure as shown in the 5~7th figure. Closing plate 2 is joined by side member l of Immediately and hat-like Toxic, and the bolt bundle of the van pasty 5 which extended from bumper 4 with this side member 1 to flange junction 3 of the upper part at the front end of closing plate 2 is carried out. Six in a figure shows bumper mature, 7 shows a Unprofessional absorption member, 8 shows a bumper facia, and bumper 4 is constituted by Humber Mature 6, such as this, energy absorption member 7, and van puff Eisha 8. This 1r] It is alike and structure is shown, for example in publication of unexamined utility model application Showa 62-12346 2 jO t information etc. Object of the Invention Since in the case of bumper fitting part style Jit mentioned above a mutual section center offsets slightly and is attached, as van pasty 5 and side member l show all over [ Q ] relation [ of junction ] "2, and a figure, The load added to bumper 4 passes van pasty 5, and is side member l. (and closing plays 1.2) It bends, and human power is Moment l- Closed and carried out. for this reason -- if big load is added to bumper 4 by collision etc., side member 1 will compromise and change in the direction of a body inner side, as shown in Drawing 8 -- Chi 1 -- To -- . setting that side member l compromises and changes only into one way to the human power load from bumper 4 since the energy absorption power at the time of generally a member breaking and changing into one way is not very large to an impact-absorbing side -- A -- better -- there is no To. For this reason, in bumper fitting part Structure mentioned above, great Urasu had to be performed in order to suppress crease modification of a side Meme river. then, the bumper fitting part structure where it was able to be immersed in impact absorption nature as the side member could pray for the present invention to one-way Only to the human power 1:A city from a bumper and it did not change -- Offer 1j (it is going to carry out -- it is a thing.) Means for solving problem In bumper fitting part style No l combined in the position which the van pasty which extended from the bumper offset from the section center to the side member as a means for solving problem which Communicating(ed) present invention" 2, A fragile site is allocated in the position of abbreviated Axis-to-axis to the load jlf input part from the van pasty of the account side member of r'iit. OPERATION He is a side member, if the large load added to the bumper is inputted into a side member via a van pasty since such a means was provided, The same mountain 1 Deformation as the fragile site in the position this portion and for an abbreviated axis is produced at the same time it bends to a load input part and produces modification by the human power moment from a van pasty. As a result, a side member crashes in the direction of an axis. EXAMPLE Hereinafter, it is based on 1st [ The ] figure~4 figure, and one example of the present invention is described. in addition -- using the same numerals for the same portion as what was shown in the drawing below the 5th figure -- il[-- a part of explanation of a portion to give shall be omitted Bumper fitting part Structure which starts the present invention in the 1~4th figure, Closing plays 1.2 are joined by side member I of a hat-like section, Although fundamental composition, such as a point that the bolt bundle of the van pasty 5 is carried out to a part of [ 11;i end 1 ] flange junction 3 of closing plate 2 with this side member 1, is the same as that of what was shown in the drawing below the 5th figure almost, It differs greatly in that the fragile site is allocated in the position for an abbreviated axis to the load input part from van pasty 5 of side member ♪ 1;. Specifically, in the case of this example, beads 9 and 10 are formed in the up-and-down corner part from the vehicles inner side on side member 1 in junction end 8 of van pasty 5, and the position for an abbreviated axis, When large-:I A is added to side member !, this bead 9 and focusing on to, side member l bends in the direction of the vehicles outside easily, and changes into it. As for 11 in a figure, it applies to a part of" 2 aspect inside side member 1, and side, and ITj is although it is wine hose Ment put together, Notch 12 is formed in the portion corresponding to the this Reinho Smend [ 1l. ] above-mentioned bead 9, and side member 1 bends easily by the direction of the vehicles outside, and changes. therefore, the case of this example -- bead 9 -- to takes and Notch l2 of in horsemen 1.11 serves as a fragile site. However, it must take 1.0, Notch l2 of in hose Ment II must not be provided altogether, and this fragile site is [ bead 9 and ] independent, respectively, or it is combined suitably and it may be made to provide it. Reinho Smend 1l. is formed so that it may go for side member's I bases lj and may become a large section gradually, and by the human power of the load from bumper 4, side member's l base breaks into one way greatly, and transforms him into it. In the case of this example, Extension / -I A 13 protrudes on the 1st page of First part import of side member 1 and closing plate 2 which were joined mutually again, When bumper 4 is displaced to the body back side by a big shock etc., human power of the load is directly carried out to side member's l tip part from this extension l3. 14 in a figure is a cross member who combines side member 1 on either side. In the above composition, if a big 6-U pile is added to bumper 4 by collision etc., the load will be bent from junction end A of van pasty 5 to side member 1, and will be inputted as a moment. then -- if side member l produces I111 Deformation (this -- it bends and strange I[2 portion is shown all over [ M ] the said figure.) near [ this ] the nf pile input part (junction end A) as shown in Drawing 3 -- almost -- simultaneous it is the same as that of a portion with this, a portion symmetrical with ■11 axis, i.e., beads 9 and 10, and Notch 12 -- it bends and produces modification (this -- it bends and a deforming part is shown all over [ N ] the said figure.). As a result, without on the other hand breaking and changing into same, side member l crashes in the shape of Accor tee-on in the direction of an axis, as shown in Drawing 4. Since extension 13 has projected to site member's 1 front end part in the case of this example, If it is obtained by bumper 4 power 11 in big load, human power will come to be directly carried out in side member's 1 direction of an axis in Shoong also from this Extension / Yong 13, and it will become easier to crash side Meme l in the direction of an axis. EFFECT OF THE INVENTION When large load is added to a bumper as mentioned above according to the present invention, in order that [ that it is the same as that of the fragile site the load input part from a side member's van pasty, this, and for an abbreviated axis ] it may bend, modification may arise and a side member may crash in the direction of an axis, Loads, such as a shock applied to the bumper as it is also at the high energy absorption power in the case of this crash, can be certainly absorbed now.
