Specific embodiment
The utility model is described in further detail below by specific embodiment combination attached drawing.
Please refer to Fig.1 to Fig. 3, the utility model is a kind of thin-wall bumper, include along vehicle-body width direction setting and
By the major ingredient thickness region 1 of near-car head forepart, positioned at 1 both ends of major ingredient thickness region and it is matched with headstock both sides turning local to become material thick
Region 2 is enclosed arranged on major ingredient thickness region 1 and the local mounting structure flange region 3 for becoming thick 2 surrounding of region of material；The major ingredient thickness area
Domain 1, local become expect that thick region 2 and mounting structure flange region 3 are an integral molding structure；
Wherein, the major ingredient thickness region 1 is mainly made of the large curved surface for waiting wall thickness, and major ingredient thickness region 1 and mounting structure turn over
The wall thickness of border region 3 is 3.0~3.5mm；Fig. 2 shows the local Section A-A figure for becoming the thick region 2 of material, and the part becomes material
Thick region 2 is connected by excessive big disc of the radius between R100~R500 to be formed, and is the even region of wall unevenness, wall thickness is
1.8mm~2.5mm, selection appearance has lines sculpted zone when selecting local change material thickness region 2；The mounting structure flange region
3 be the contour area of entire bumper；
The local thick region 2 of material that becomes includes wall towards headstock turning equipped with glue region 201, the glue region 201 that subtracts is subtracted
It is thick it is most thin subtract glue portion 202 and arranged on the transition region 203 subtracted around glue portion 202, the wall thickness for subtracting glue portion 202 subtracts glue less than this
The wall thickness of 202 surrounding transition region 203 of portion and subtract the wall thickness in glue region 201 and be gradually reduced from transition region 203 to glue portion 202 is subtracted；Subtract
Glue portion 202 is the most thin place of bumper wall thickness, is dissipated to the transition region 203 for respectively subtracting 202 both sides of glue portion, wall thickness gradually tends to just
Often；It is typically all the region for being provided with turning that front and this of bumper, which subtract 201 corresponding position of glue region, because turning moulding rigidity
It is most strong, so glue can be subtracted at its back side；In the utility model embodiment, it is to subtract glue portion 202a, the by first to subtract glue region 201
Two subtract glue portion 202b, the 3rd subtract the triangular structure that glue portion 202c and corresponding transition region 203 are formed.
Preferably, the mounting structure flange region 3 is used to accurately for bumper to be installed to vehicle body other zero
On part, including：Screw mounting base 301 above major ingredient thickness region 1, the positioning bar piece arranged on 1 lower section of major ingredient thickness region
302nd, arranged on the local several ring sets buckle 303 become above the thick region 2 of material, arranged on the local several spiral shells for becoming 2 one end of the thick region of material
Bar screw mounting hole 304, the cantilever snaps 305 arranged on 2 bottom of major ingredient thickness region 1 and the local thick region of change material.
Specifically, the bumper further includes the license plate mounting portion 4 among major ingredient thickness region 1, Fig. 3 shows this
The Y0 sectional views of utility model embodiment, that is, longitudinally asymmetric central plane, in the utility model embodiment, the wall of license plate mounting plate
Thickness is 2.6mm；The license plate mounting portion 4 is equipped with 6 spring nut mounting bases, and shape is square, and square step is with peace
Hole is filled, 4 of outside surrounding are the first spring nut mounting base 401, and horizontally disposed 2 of inside is installed for the second spring nut
Seat 402；Wherein, the first spring nut mounting base 401 meets national standard laws and regulations requirement and meets Chinese Industrial Standards (CIS), the second reed spiral shell
Female mounting base 402 meets European standard.
The advantages of the utility model is：
1）Bumper weight is alleviated, reduces cost
The utility model has carried out subtracting glue at the bumper back side corresponding to automobile corner region, because turning moulding rigidity
It is most strong, it so both ensure that the intensity and stiffness of bumper, product appearance quality zero defect, and the weight of bumper is alleviated,
Efficiently solve the problems, such as that bumper is light-weighted, meanwhile, the bumper of thin-walled reduces the cost of bumper.
2）It is highly practical
The license plate mounting portion 4 of the utility model is mounted with the spring nut mounting base for meeting two kinds of various criterions simultaneously,
Using the technology automobile simultaneously can Europe and Discussion on Chinese Listed, it is highly practical.
The above content is combine specific embodiment further detailed description of the utility model, it is impossible to assert
The specific implementation of the utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field
For, without departing from the concept of the premise utility, several simple deduction or replace can also be made, should all be considered as category
In the scope of protection of the utility model.
