Front bumper structure

[Detailed Description of the Invention]

The present invention relates to the front bumper structure of a car. As a bumper for cars, what gave buffer nature to the bumper itself is used abundantly in recent years. If Drawing 1 explains this, 1 shows a front bumper and constitutes the front bumper 1 from bumper fascia 3 which consists of elastic materials which cover metal bumper armature 2 and this armature 2, such as rubber and resin. Armature 2 constitutes the closed section from base plate 2a and back plate 2b, Pan Perth tee 4 is attached to the side part of this back plate 2b, the pan Perth tee 4 is inserted in mounting hole 6 of radiator core support 5, and he equips frontside member 7, and is trying to support front bumper 1. as this pan Perth tee 4, a shock absorber is usually used, and at the time of the front collision of a car, with the shock absorber 4, it is made to buffer and comes out. this Flandpa / par 1 -- getting twisted -- carrying out a Yo Si buffer also in the time of the light impact of a car, at elastic deformation of bumper 7 Eisia 3, when that collision load is small And the plastic deformation of a bumper can be avoided and the passerby's safety measures can also be planned by elastic deformation of this bumper 7 Eisia 3. And when collision load is big, the bumper 1 whole can retreat with bumper fascia 30 elastic deformation, and it can be made to buffer with shock absorber 4. By the way, even if it is in the car provided with such a front bumper 1, front spoiler 8 is allocated in front bumper 1 (7) lower part like illustration for the object of raising running stability, in many cases. The frontside member who combined this front spoiler 8 with the front of the bottom of radiator core support 5 (he carries out bracket 10 Wo combination -9, and is trying to fix to this bracket lO bolt Nut 11) However, it is although front bumper 1 retreats and a buffer action is carried out with shock absorber 4 with this conventional composition at the time of the front collision of a car, there is no position change of front spoiler 8, therefore core front spoiler 8 interferes with a partner object -- plastic deformation -- or it damaged and carried out, and obtained one and there was a problem. also when this front spoiler 8 interfered in a curbstone etc., since [ which fixes to bracket 10 and is / come out and / in it at two or more of those places ] only, rigidity was insufficient and there was fault that Summer match of breakage was high. making board thickness of front spoiler 8 and bracket 10 into a dog on the other hand, since it is such -- rigid To worship -- although things are also considered, now, the amount of body l will be increased in vain, and the new problem of causing fuel consumption aggravation will be produced. Even if a front bumper carries out retreat movement of the present invention with a shock absorber in view of this conventional problem at the time of the front collision of a car, It is considered as the providing-front bumper structure front spoiler of the lower part interferes with partner object, and kept it from transforming thru/or damaging all object. if it is in the present invention in order to achieve the above-mentioned object -- a bumper armature and bumper 7 -- Asia Tokara -- installing the above-mentioned armature of front bumper 1 main part below if front bumper 1 main part retreats by existence of a shock absorber by [ of this armature extendedly installed part ] providing a front spoiler positively at the time of the front collision of a car, a front spoiler retreats to the bumper and one, and it will be made not to interfere with a partner object and will come out. Hereinafter, with a drawing, the same numerals are given to the same portion as the above-mentioned conventional composition, and the example of the present invention is explained in full detail. That is, if it is in the present invention, as it is shown in Drawing 2, it is with bumper armature 2, Front bumper 1 main part 1 which consists of bumper 7 Eisia 3 which consists of an elastic material which -ed Wandering the armature 2, four shock absorbers pass -- body 7, specifically a frontside member, -- several -- it is in phrase person Configuration and the above-mentioned armature 2 is installed below in the state where that pace Bra 2a and back plate 2b were polymerized, and front spoiler 8 is provided in the front of this extendedly installed part 12, and it comes out to it. obtaining outside a figure, carrying out outside-air-intake Ro 13 Wo formation for JEITA, and coming out to two or more places at the above-mentioned extendedly installed part 12 -- being certain -- on the other hand Are carrying out piece of junction 8ai formation at front spoiler 8 at the part corresponding to the above-mentioned fresh-air intake 13, and it joins to inferior border 7 lunge 13 a of this piece of junction 8ai fresh-air intake 13, and spoiler inferior border 8b'4 A 1 mature extendedly installed part 12 carries out inferior border 12aK junction, and it is several phrase Over. projection amount t2 of spoiler 8 is set up smaller than projection of armature 2, and 1i-4I, and also when it deforms elastically until bumper fascia 3 contacts the armature 2 front at the time of a front collision, a partner object is kept from interfering in spoiler 8, and it comes out of it. the above example structure -- getting twisted -- if front bumper 1 main part 1 carries out retreat movement by existence of shock absorber 4 at the time of the front * collision of a car Front spoiler 8 also carries out retreat movement at the front bumper 1 main part 1 and one, and moreover, it is made smaller than projection amount 1. of bumper armature 2, appears in the projection nt2, and is [ certain ] a sake, Even if it deforms elastically until bumper fascia 3 contacts the armature 2 front, a partner object cannot interfere in the front spoiler 8, therefore the plastic deformation of front spoiler 8 or breakage can be avoided. When front spoiler 8 interferes in a curbstone etc., that collision input can act on shock absorber 4, the bumper 1 main-part 1 whole can carry out retreat movement like the above-mentioned, and it can stop small modification of front spoiler 8 thru/or a breakage degree as much as possible also in this case. The example shown in Drawing 3 forms front spoiler 8A with elastic materials, such as rubber and resin. It protrudes on two or more hooking portions 80, appears in the inferior border terminal of spoiler 8A, and is a certain one side, V Mounting hole 12bk formation is carried out on the armature 2 lower-end edge, elastic engagement is carried out on the one edge of piece of stop 8dfc fresh-air intake 13 which protruded on the superior border of spoiler 8A, and it fits in and engages with inferior border hooking portion 3ci mounting hole 121, and is attachment. the structure of this example -- getting twisted -- when the same effect as the account example of Ail is acquired at the time of the axial collision for ill[of a car and front spoiler 8 interferes in a curbstone etc., there are modification and an advantage of front spoiler 8 which can carry out double former flexibly with the elasticity of the very thing. As mentioned above, a front spoiler is provided in one, and it appears in the bottom extendedly installed part of Front desk 1 armature according to the present invention, and is [ certain ] a sake, It is Frono (even if Iron 1 main part carries out retreat movement) by existence of a shock absorber at the time of the front part axis collision of a car. It carries out south [ of the practically big effect that it can be beforehand prevented from a front spoiler carrying out retreat movement at the bumper 1 main part, therefore a front spoiler interfering with a partner object, and being changed thru/or damaged ].
