The invention belongs to the field of design and manufacturing of car body parts, and particularly relates to an installation structure of a rear bumper. The installation structure of the rear bumper comprises a rear bumper body, a body side outer plate and a rear bumper side installation supporting frame, wherein an n-shaped flanging part is arranged at the joint of the rear bumper body and the body side outer plate and inserted into a seam between the rear bumper body and the body side outer plate; a limiting rib is arranged on the side, opposite to the body side outer plate, of a suspension extending section of the flanging part; the gap between the limiting rib and the body side outer plate is L4, the gap between the edge of the rear bumper and the body side outer plate is L5, and L4 is smaller than L5. By means of a matching structure of the rear bumper and a body side, the shrinkage problem of the matching area of the rear bumper and the body side is effectively solved, and meanwhile the problem of interference paint falling of the rear bumper and the body side is solved.
Description
Technical field
The invention belongs to automobile body part and manufacture and design field, be specifically related to a kind of rear bumper mounting structure.
Background technology
In the design of passenger car rear bumper system, in the position that rear bumper coordinates with gusset, rear bumper needed to provide turnup structure with coordinating of gusset, with gusset mating area, this structure can be protected after causing occurs that large area shrink (is protected outer surface and be there will be an obvious indenture with flange corresponding position after namely, this is owing to the shrinkage characteristics of Shooting Technique causes, the moulding that thickness is more big shrinks more obvious, therefore the shrinkage degree at flange place is more than other positions, thus causing the generation of shrink phenomenon), thus affecting the appearance property of car load, and then affect the satisfaction of client；Rear bumper is less with gusset fit clearance simultaneously, due to gusset or the rear deformation protected, gusset can be caused to coordinate with rear guarantor zero clearance (interference) occurs, there is paint problem thus protecting in assembling process after causing, and then cause that exemplar is scrapped, also result in protect after in car load driving process and occur rubbing off paint problem with gusset, thus causing customer claims.
Summary of the invention
It is an object of the invention to provide the turnup structure that a kind of rear bumper preventing shrink generation coordinates with gusset and prevents gusset from interfering, solve the shrink problem of rear bumper and gusset mating area and the problem painted is fallen in guarantor and gusset interference afterwards.
For achieving the above object, the invention provides techniques below scheme: a kind of rear bumper side mounting structure, including after break even body, side-wall outer-plate and rear protect side mounting bracket, break even after described body and side-wall outer-plate joint is provided with the turn-up portion of a few font, in the crack that described turn-up portion breaks even between body and side-wall outer-plate after being inserted in, side relative with side-wall outer-plate in described turn-up portion is provided with limit rib, gap between described limit rib and side-wall outer-plate is L4, gap between rear guarantor's body edges and side-wall outer-plate is L5, described L4 < L5；
Preferably, the inner side cell body width of described turn-up portion is L1, turn-up portion and after the fillet between outside that breaks even be R, the distance between extended line and the R angle end of described L1 is L2, described L2≤1.3mm；
Preferably, the inner side cell body width of described turn-up portion is L1 >=1mm；
Preferably, described turn-up portion contiguous after break even the thickness of body edge less than the thickness at other each position；
Preferably, described limit rib is multiple, and arranges along the outside uniform intervals of turn-up portion；
Preferably, the inner of described turn-up portion is protected between side mounting bracket and side-wall outer-plate after being clipped in；
Preferably, the minimum thickness L3 >=1.5mm of described turn-up portion.
The method have technical effect that: the rear guarantor of the present invention and the fit structure of gusset can protect the shrink problem with gusset mating area after effectively solving, paint problem is fallen in the interference can protected after solving with gusset simultaneously.

Detailed description of the invention
Such as Fig. 1, shown in 2, a kind of rear bumper side mounting structure, including after break even body 10, side-wall outer-plate 20 and rear guarantor side mounting bracket 30, break even after described body 10 and side-wall outer-plate 20 joint is provided with the turn-up portion 11 of a few font, described turn-up portion 11 breaks even in the crack between body 10 and side-wall outer-plate 20 after being inserted in, in described turn-up portion 11, the side relative with side-wall outer-plate 20 is provided with limit rib 12, gap between described limit rib 12 and side-wall outer-plate 20 is L4, after the gap between body 10 edge and side-wall outer-plate 20 that breaks even be L5, described L4 < L5.
Further, as shown in Figure 3,4, the inner side cell body width of described turn-up portion 11 is L1, turn-up portion 11 and after the fillet between body 10 lateral surface that breaks even be R, the distance between extended line and the R angle end of described L1 is L2, described L2≤1.3mm.
Preferably, the inner side cell body width of described turn-up portion 11 is L1 >=1mm.
Preferably, described turn-up portion 11 contiguous after break even the thickness of body 10 edge less than the thickness at other each position.
Preferably, described limit rib 12 is multiple, and arranges along the outside uniform intervals of turn-up portion 11.
Preferably, the inner of described turn-up portion 11 is protected between side mounting bracket 30 and side-wall outer-plate 20 after being clipped in.
Preferably, the minimum thickness L3 >=1.5mm of described turn-up portion 11.
Cross section as shown in Figure 4 is the primary mounting structure of rear bumper anti-shrinkage, wherein internal flange width L1 is the thickness of die side slide block, in order to ensure the life-span of slide block, generally require L1 >=1mm, the preferred L1=1mm of this present invention, the wherein distance L2 of R angle, rear bumper flange place end and L1 extended line, this distance is the major influence factors shunk, the present invention moves at broken even as far as possible backward by the shrink line edge of body 10, generally require L2≤1.3mm, the preferred L2=1.3mm of the present invention, rear bumper flange 11 minimum thickness is designated as L3, in order to ensure the reliability of flange intensity and fit structure, generally require L3 >=1.5mm, the preferred L3=1.5mm of the present invention.
Cross section as shown in Figure 2 break even after being body 10 coordinate with side-wall outer-plate 20 prevent interfere fit structure, wherein L4 is rear bumper flange upper limit muscle 5 and side-wall outer-plate distance, L5 breaks even after being the edge of body 10 and the minimum range of side-wall outer-plate 20 flange, generally require that L3 is less than L4, protect flange limit rib 12 after ensureing first to contact with side-wall outer-plate 20, thus breaking even after avoiding, interfering occur in body 10 and side-wall outer-plate 20, it is possible to broken even after being controlled by the height of limit rib 12 body 10 minimum range with side-wall outer-plate 20.
