Abstract
The invention provides a front bumper and fender matched flanging sink-mark-prevention structure. It is ensured that a front bumper and a fender are well matched on the clearance plane difference while sink marks of the front bumper are reduced or eliminated, and the appearance attractiveness is improved. The front bumper and fender matched flanging sink-mark-prevention structure comprises the front bumper, the fender and a front bumper support. A U-shaped flanging with the opening direction towards the front bumper is arranged at the abutting end of the front bumper and the fender. A clamping hole is formed in the flanging. The front bumper support is fixed to the fender, and a clamp matched with the clamping hole is arranged on the front bumper support. The U-shaped flanging is arranged at the end of the front bumper, and therefore the end of the front bumper is in smooth transition. The sink marks of the end of the front bumper can be reduced or eliminated, and the phenomenon that due to sharp friction between the end of the front bumper and the fender, the appearance of the fender is damaged can be completely eradicated. In addition, compared with a traditional T-shaped flanging, the U-shaped flanging is easier to control in the stamping process, and therefore the clearance between the front bumper and the fender is easier to control.
Description
Technical field
The present invention relates to a kind of front bumper coordinates flange sink-mark prevention structure with beater or beat-up.
Background technology
With the improvement of people's living standards, automobile gradually comes into huge numbers of families, and beautiful, the unique automobile layer of moulding goes out not
Thoroughly, the fiting effect of wherein front bumper and beater or beat-up occupies a critically important part for automobile side face moulding, outside automobile
See and minute design has very big impact to consumer's purchase car.
At present, the fit clearance of front bumper and wing plate of automobile body is critically important one of quality height of vehicle appearance
Point, requirement of the Ge great main engine plants to outward appearance also increasingly pursues ultimate attainment, for the gap of overall appearance, between some pursuits zero
Gap, makes moulded cleanliness strong；What is had is then that overall gap is larger, highlights car load style.As shown in Figure 1, 2, front bumper 1
This effect is reached with being combined into, "T"-shaped flange 10 is designed in the end of front bumper 1 mostly, its front bumper with beater or beat-up 3
Support 2 is also exposed to bodywork surface, and the impact for negatively bringing is exactly that front bumper 1 can produce in appearance slight shrink mark, and
And the bad control in the gap between front bumper 1 and front bumper bracket 2, beater or beat-up 3, affect car load outward appearance.
The content of the invention
The purpose of the present invention is to propose to a kind of front bumper coordinates flange sink-mark prevention structure with beater or beat-up, insure before guarantee
Thick stick while clearance surface difference has and coordinates very well, reduces or eliminates the shrink mark of front bumper with beater or beat-up, improves appearance looks elegant degree.
The front bumper of the present invention coordinates flange sink-mark prevention structure to include front bumper, beater or beat-up and front insurance with beater or beat-up
Thick stick support, it is critical only that the front bumper is provided with " u "-shaped of the opening direction towards front bumper with the end that beater or beat-up offsets
Flange, the flange is provided with hole clipping, and the front bumper bracket is fixed on beater or beat-up, the front bumper bracket be provided with
The clamp that the hole clipping coordinates.
" u "-shaped flange is set in the end of front bumper, the end rounding off of front bumper is made, it is possible to reduce or disappear
Except the shrink mark at this, it is possible to prevent the beater or beat-up outward appearance caused because of the sharp friction between front bumper end and beater or beat-up
It is impaired.In addition, " u "-shaped flange is compared to traditional "T"-shaped flange, easily control during punching press, therefore be also easier to control
The gap of front bumper and beater or beat-up.
Further, it is to reduce the gap between beater or beat-up and front bumper, improves aesthetics, and is conducive to beater or beat-up
Punch forming, to ensure the quality in the outer A faces of beater or beat-up, the edge of the beater or beat-up is provided with and front bumper " u "-shaped flange outside
The adaptation flange being close to.
Further, the clamp is arranged on the stretch section of front bumper bracket, after the clamp is fastened with hole clipping, card
Son to hole clipping applies elastic force, so that the end of front bumper is drawn close to the direction of beater or beat-up and automobile axis.Using clamp
Elasticity, the end that can automatically make front bumper is drawn close to the direction of beater or beat-up and automobile axis, so as to reduce beater or beat-up with
Gap between front bumper, improves aesthetics, it is possible to effectively prevent clamp from deviating from hole clipping.
Specifically, the edge of the flange is provided with extension, and the hole clipping is arranged on extension, the extension with
Angle α between front bumper end is less than 90 degree and more than 45 degree；The clamp is arranged at extension away from the one of beater or beat-up
Side.So after clamp snaps in hole clipping, due to the elastic force of clamp itself（There is provided by the stretch section of front bumper bracket）, clamp meeting
Apply an active force away from clamp direction to hole clipping, the active force is acted on extension, is inclined by front bumper end
The extension in portion is decomposed into the component towards beater or beat-up direction and the component towards automobile axis direction, so that front bumper
End draw close to the direction of beater or beat-up and automobile axis.
Further, the stretch section of the front bumper bracket is by the first stretch section, the second stretch section, the 3rd stretch section structure
Into first stretch section is connected and perpendicular to the extension with the body of front bumper bracket, and second stretch section connects
Be connected to the end of the first stretch section and parallel with extension, the 3rd stretch section be connected to the middle part of the second stretch section and with prolong
Stretch section vertically, the clamp is located at the end of the 3rd stretch section.By the cooperation of three stretch sections, can provide bigger for clamp
Elastic force, and the direction of the elastic force is towards beater or beat-up direction and the direction of automobile axis such that it is able to better control over front guarantor
The position of dangerous thick stick.
The flange shape that the present invention passes through improvement front bumper end, is ensureing front bumper with beater or beat-up in clearance surface difference
While having cooperation very well, the shrink mark of front bumper is reduce or eliminated, improve appearance looks elegant degree.
