Description
Technical field
The invention belongs to automobile body parts to manufacture and design field, and in particular to a kind of rear bumper mounting structure.
Background technique
In the design of passenger car rear bumper system, in the position of rear bumper and side wall cooperation, rear bumper and side wall
Cooperation need to provide turnup structure, this structure, which is protected after will lead to side wall mating area, to there is large area and shrinks (to protect after i.e. outer
Surface and flange corresponding position will appear an obvious dent, this is because caused by the shrinkage character of Shooting Technique, thickness
Bigger moulding contraction is more obvious, therefore the shrinkage degree at flange is greater than other positions, so as to cause the production of shrink phenomenon
It is raw), to influence the appearance property of vehicle, and then influence the satisfaction of customer；Simultaneously rear bumper and side wall fit clearance compared with
Deformation that is small, protecting due to side wall or afterwards, will lead to side wall and it is rear protect cooperation and zero clearance (interference) occur, filled so as to cause rear guarantor
With occurring paint problem in the process, and then exemplar is caused to be scrapped, protects after also resulting in vehicle driving process and rub with side wall
Paint problem is wiped, so as to cause customer claims.
Summary of the invention
The object of the present invention is to provide a kind of rear bumper for preventing shrink from generating and side wall cooperation and prevent side wall dry
The turnup structure related to, to solve the problems, such as that shrink and rear protect of rear bumper and side wall mating area fall asking for paint with side wall interference
Topic.
To achieve the above object, the present invention provides following technical schemes: a kind of rear bumper side mounting structure, including
After break even body, side-wall outer-plate and it is rear protect side mounting bracket, the body that breaks even after described is with the side-wall outer-plate place of docking equipped with zigzag shape
Turn-up portion, in the crack that the turn-up portion is broken even after being inserted between body and side-wall outer-plate, in the turn-up portion with side-wall outer-plate phase
Pair side be equipped with limit rib, gap between the limit rib and side-wall outer-plate is L4, rear to protect body edges and side-wall outer-plate
Between gap be L5, the L4 < L5；
Preferably, the inside groove body width of the turn-up portion is L1, turn-up portion and after the fillet that breaks even between outside
For R, the distance between the extended line of the L1 and the angle R end are L2, the L2≤1.3mm；
Preferably, the inside groove body width of the turn-up portion is L1 >=1mm；
Preferably, the thickness of body edge of breaking even after the turn-up portion is neighbouring is less than the thickness at other each positions；
Preferably, the limit rib is multiple, and is arranged along the outside uniform intervals of turn-up portion；
Preferably, it is protected between side mounting bracket and side-wall outer-plate after the inner end of the turn-up portion is clipped in；
Preferably, minimum thickness L3 >=1.5mm of the turn-up portion.
The technical effects of the invention are that: the fit structure of rear guarantor and side wall of the invention are protected after can effectively solving and side
The shrink problem of mating area is enclosed, while paint problem is fallen in the interference protected after can solve with side wall.
Detailed description of the invention
Fig. 1 is rear guarantor and side-wall outer-plate assembling structure schematic diagram of the invention；
Fig. 2 is the A-A sectional view of Fig. 1；
Fig. 3 be it is of the invention after break even body partial structural diagram；

Specific embodiment
As shown in Figure 1, 2, a kind of rear bumper side mounting structure, including after break even body 10, side-wall outer-plate 20 and after
Side mounting bracket 30 is protected, the body 10 that breaks even after described is equipped with the turn-up portion 11 of zigzag shape, the flange with 20 place of docking of side-wall outer-plate
In the crack that portion 11 is broken even after being inserted between body 10 and side-wall outer-plate 20, opposite with side-wall outer-plate 20 one in the turn-up portion 11
Side is equipped with limit rib 12, and gap between the limit rib 12 and side-wall outer-plate 20 is L4, after break even outside 10 edge of body and side wall
Gap between plate 20 is L5, the L4 < L5.
Further, as shown in Figure 3,4, the inside groove body width of the turn-up portion 11 is L1, and turn-up portion 11 breaks even with after
Fillet between 10 lateral surface of body is R, and the distance between the extended line of the L1 and the angle R end are L2, the L2≤1.3mm.
Preferably, the inside groove body width of the turn-up portion 11 is L1 >=1mm.
Preferably, the thickness of 10 edge of body of breaking even after the turn-up portion 11 is neighbouring is less than the thickness at other each positions.
Preferably, the limit rib 12 is multiple, and is arranged along the outside uniform intervals of turn-up portion 11.
Preferably, it is protected between side mounting bracket 30 and side-wall outer-plate 20 after the inner end of the turn-up portion 11 is clipped in.
Preferably, minimum thickness L3 >=1.5mm of the turn-up portion 11.
Section as shown in Figure 4 is the primary mounting structure of rear bumper anti-shrinkage, wherein internal flange width L1 is mould
The thickness of tool side slide generally requires L1 >=1mm, the preferred L1=1mm of this present invention to guarantee the service life of sliding block, wherein after
The angle R end and L1 extended line distance L2 at bumper flange, this distance are the major influence factors shunk, and the present invention will shrink
Line break even backward as far as possible body 10 edge it is mobile, generally require L2≤1.3mm, the preferred L2=1.3mm of the present invention, rear bumper
11 minimum thickness of flange is denoted as L3, in order to guarantee the reliability of flange intensity and fit structure, generally requires L3 >=1.5mm, this
Invent preferred L3=1.5mm.
Break even after being body 10 and side-wall outer-plate 20 of section as shown in Figure 2 cooperates the fit structure for preventing interference, wherein L4
It is rear bumper flange upper limit muscle 5 and side-wall outer-plate distance, L5 breaks even the edge and 20 flange of side-wall outer-plate of body 10 after being
Minimum range generally requires L3 to be less than L4, first contacts to protect flange limit rib 12 after guaranteeing with side-wall outer-plate 20, to avoid
After the body 10 that breaks even interfere with side-wall outer-plate 20, broken even outside body 10 and side wall after being controlled by the height of limit rib 12
The minimum range of plate 20.
